Backgrounds: As the COVID-19 pandemic continues, the university students population is one of the high risk and vulnerable groups. This study analyzed the status of student's mental health, including anxiety and depression caused by COVID-19, and its related factors among a university students in Korea. Methods : Our study subjects included university students in Korea. The survey items included general characteristics, teaching methods, physical activity, eating habits (SDBQ-L), weight-related questions, general anxiety disorder-7(GAD-7), and depression symptoms checklist. Frequency analysis, chi-square test, and logistic regression analysis were performed and data was analyzed using R version 4.1.2 program. Results : The prevalence of anxiety complaints was 5.5%, while the prevalence of depression complaints was 30.8%. In the multivariable logistic regression analysis of factors influencing anxiety, anxiety occurred 19.081 times (95% confidence interval (CI): 2.352-154.807) in the group with unhealthy diet (p<0.01). While in the multivariable analysis to identify factors affecting depression, women were 2.607 times significantly higher (95% CI: 1.255-5.415) than men, 0.407 times (95% CI:0.197-0.840) for residents of the metropolitan area, 3.418 times higher (95% CI:1.633-7.198) for unhealthy dietary people, and 2.225 times higher (95% CI: 1.080-4.582) for weight gainers (p<0.05). The type of class had no effect. Conclusions: COVID-19 and its associated interventions had negative effects on the mental health status including anxiety and depression in university students in Korea. Based on our results we recommend developing mental health interventions and prevention strategies for students in all universities in Korea.

This study investigates the effects of online English writing instruction on university students' writing performance and their anxiety. A total of 34 participants completed the pre- and post- writing tests as well as the surveys regarding perceived anxiety toward English writing. Reflection papers and interviews were employed to triangulate the results of the questionnaires. Quantitative analysis of learners' writing outcomes and surveys revealed that online writing instruction helped improve students' writing skills and reduce writing anxiety. The interviews and reflection papers demonstrated that learners found the writing instruction helpful in reducing somatic anxiety, avoidance behavior, and cognitive anxiety. The current study suggests that adopting non-face-to-face online writing instruction aids EFL students in developing their writing and alleviating writing anxiety.

The use of holographic standardized patient (HSP) with mixed reality can provide students with the opportunity to enhance clinical reasoning skills. This is still relatively new, so there is a lack of guidelines for educators. Thus, we aimed to develop the instructional model of HSP-based education, for enhancing clinical reasoning skills in undergraduate healthcare education, which could systematically guide educators in designing and implementing HSP-based teaching and learning activities appropriately. Using a design and development research, a theoretically constructed initial mode in this study was iteratively improved and underwent validation through expert review and model usability test. Features of the model were discussed, along with theoretical and practical implications and suggestions for further research.

This study was a cross-sectional descriptive survey study that confirms the effect on subjects that prefer clinical practice in order to prepare basic data for efficient clinical practice guidance for nursing college students. The study participants were 201 students attending C University, and the data collection period was from October 1 to October 15, 2022. The collected data were analyzed using SPSS 18.0 as descriptive statistics, Pearson correlation, Chi square test, ANOVA test, and Multiple regression test. As a result of the analysis, it was found that clinical decision-making and critical thinking were correlated under the statistical significance level (r=.730, p<0.01). The most favorite clinical practice department was community nursing, and male students preferred community nursing the most (Male=45.6%, χ²=.000), female students were found to prefer similar levels of practical subjects with child nursing , adult nursing, and maternal nursing(χ²=000).Clinical decision-making was found to be higher in students who preferred community nursing at a statistical significance level than those who preferred child nursing (F=4.91, p<0.01). Critical thinking was higher among students who preferred adult nursing than those who preferred other subjects (F=4.65, p<0.01). Through the analysis results, it was found that general characteristics vary, but clinical decision-making ability and critical thinking affect the preference of clinical practice subjects. Therefore, based on the results of this study, the professor of clinical practice suggests the development of a program to foster clinical decision-making and critical thinking to make students interested in clinical practice subjects.

The purpose of this study is to explore the factors affecting the satisfaction level of the disabled and their families. for proposing various future types of residential facilities required by parents of adults with disabilities.

The digital age start in earnest with the widespread use of the Internet. As a digital product, virtual idols bring new value to the design and dissemination of commercial brand images. "Luo Tianyi" is the world's first avatar and VOCALOID voice bank of Chinese. It has a large number of fans in China and is widely used in brand promotion. Therefore, "Luo Tianyi" is taken as the research object. Initially, we investigated the virtual idols through books, literature on the internet and other materials. Then we discussed semiotics and theories related to culture code brand design methodology (CCBD). After that, putting the above theories into practice, combined with brand design cases, we analyzed the strategy of virtual idols in brand promotion and dissemination, at last, we have the conclusion as followed. The results show that the virtual idols, visual symbol of "Luo Tianyi" can express the Index and Symbol corresponding to the brand information according to the characteristics of the brand. As an image of cultural code, "Luo Tianyi" can present three visual images at the same time, which are contemporary, traditional and future. In addition, these three visual images are presented in a strong and weak combination, which has a positive impact on the visual communication of the brand.

For proper socialization of children the psychological and emotional state of parents that affect children is very important. Recently, while interest in various psychological behavioral problems of children has increased, various studies have been conducted on parental psychology that affects children's emotions. In particular, due to COVID-19, stress has increased throughout society, and it has made parental psychology and childrearing more difficult. Therefore, we aim to investigate the effects of psychological factors, among the variables of various parents that affect children's problem behavior in this study. As a result of this study, it can be confirmed that there is a difference in the effect of parental depression on children's internalizing and externalizing behaviors. Parental depression had a significant positive effect on children's internalizing behavior with 𝛽 =.34, p<.001. In other words, the higher the parents' depression, the higher the child's internalization behavior. And parental depression was found to have a significant effect on children's externalizing behavior, with 𝛽 =.81, p<.001. This also means that the higher the parents' depression, the higher the child's externalizing behavior. Therefore, it can be seen that parental depression is an important factor influencing both children's internalizing and externalizing behaviors.

The purpose of this study is to investigate whether there was a difference in the degree of boredom between groups according to whether they participated in the self-control program, and to verify whether the individual's degree of boredom was lowered before and after the self-control program. 148 college students participated in this study. The results showed that the experimental group who participated in the self-control program had significantly lower boredom than the control group. Furthermore, the boredom of individuals who participated in the self-control program was significantly lower after participating in the self-control program than before. This study showed that self-control behaviors significantly affect boredom. Based on the results, theoretical and practical implications to cope with boredom were discussed.

This study examines the association between ownership structure and labor investment efficiency. Specifically, this study investigates whether owner-manager firms, where managers own a large percentage of shares in the firm, involve in more efficient labor investment. Based on the management entrenchment hypothesis, managers are more likely to make labor investment decisions to maximize their private benefits rather than creating value for shareholders, resulting in lower efficiency in labor investment. On the other hand, according to the incentive alignment hypothesis, managers tend to make labor investment decisions that will improve future firm performance as their interests are aligned with those of shareholders. In this situation, owner-manager firms are expected to have higher efficiency in labor investment. Our empirical results show that owner-manager firms engage in more efficient labor investment, which contributes to long-term firm value. This study provides empirical evidence that firms' labor investment behavior can vary depending on the characteristics of the ownership structure.

North Korea's development and deployment of nuclear weapons increases Pyongyang's diplomatic bargaining leverage. It is a strategic response to counteract the great expansion in US leverage with the collapse of the USSR. Post-Cold War American influence and hegemony is justified partly by claiming victory in successfully containing an allegedly imperialist Soviet Union. The US created and led formal and informal international institutions as part of its decades-long containment grand strategy against the USSR. The US now exploits these institutions to expedite US unilateral global preeminence. Third World regimes perceived as remnants of the Cold War era that resist accommodating to American demands are stereotyped as rogue states. Rogue regimes are criminal offenders who should be brought to justice, i.e. regime change is required. The initiation of summit diplomacy between US President Trump and North Korean leader Kim Jong-un occurred following the January 2018 Hawaiian ballistic missile false alarm. This event and its political consequences illustrate the efficacy of nuclear weapons as bargaining leverage for so-called rogue actors. North Korea is highly unlikely to surrender those weapons that were the instigation for the subsequent summit diplomacy that occurred. A broader, critical trend-focused strategic analysis is necessary to adopt a longer-term view of the on-going Korean nuclear crisis. The aim would be to conceptualize long-term policies that increase the probability that nuclear weapons capability becomes a largely irrelevant issue in interaction between Pyongyang, Seoul, Beijing and Washington.

Psychological support is crucial in navigating one's academic and professional lives, especially for students living abroad and pursuing higher education. This study aims to explore the narratives of social support seeking in a group of Korean international graduate students in an urban university setting in the United States. Qualitative research method of narrative approach was used to examine how three Korean graduate students exchanged psychological support. Analysis of interviews, observations, and documents found that four types of social support (informational, instrumental, appraisal, and emotional) were being exchanged and that emotional support was accessible predominantly in individual meetings than in group gatherings. Additionally, the reasons for abstaining from initiating group gatherings are discussed in relation to the Korean culture where participants were mindful of not infringing on each other's time. These findings inform theory on socio psychological support seeking and its relation to cultural values and offer practical insights into psychological support in international students in higher education settings.

The South Korean military has undergone four changes in operating methods since its inception with 31 nursing officers in August 1948. While it initially began as a special unit for nursing and other specialized services, it later expanded to include various fields including technology, administration, and special forces. However, analysis shows that there have been few significant changes in how it operates and remains largely centered around technology, administration, and special forces. With the development of advanced science and technology and a decrease in military resources, there is a need for the South Korean military to proactively expand its use of female personnel, as has been done by the US military, Canadian military, Israeli military with female conscription, and Norwegian military. In order to achieve this, there needs to be a cultural shift towards co-ed military units, improvements in facilities and equipment, adequate pay and benefits, and resolution of childcare issues through institutional reforms.

Experts are concerned about the lack of troops and security vacuum due to the low birth rate in the Republic of Korea. They consider policies to expand the proportion and role of female soldiers to address these issues. In this regard, We would like to introduce the successful use of female personnel in the Ukrainian military and draw implications for the Korean military. This will provide a clue to offset the shortage of troops in the Republic of Korea.

This study is for manned-unmanned teaming battles for future ground combat victories. The composition of the study is as follows. The introduction to Chapter 1 presents the necessity of this study from a macro perspective, Chapter 2, the review of the complex combat system for both manned and unmanned introduced the paradigm shift of the future battlefield and the cyber area that is superconnected to the network in future wars. Chapter 3 analyzed the combined combat system of manned-unmanned teaming in advanced military countries through the cases of the United States and Israel. In Chapter 4, after discussing the direction of the development of combat performance of the Korean Army, was concluded in Chapter 5. In other words, the purpose of this study is that as the concept of fighting artificial intelligence robots and military innovation changes, the method of performing battles must be changed in order for our military to win the battle.

This study focuses on the development of intelligent combat robot systems for future warfare. The research is structured as follows: First, the introduction presents the rationale for researching intelligent combat robots and their potential to become game changers in future warfare. Second, in the context of the intelligent robot paradigm, this study proposes the need for military organizations to innovate their combat concepts and weapon systems through the effective utilization of Artificial Intelligence, Cognitive, Biometric, and Mechanical technologies. This forms the theoretical background of the study. Third, the analysis of intelligent robot systems considers five examples: humanoid robots, jumping robots, wheeled and quadrupedal pack robots, and tank robots. Finally, the discussion and conclusion propose that intelligent combat robots should be selected as game changers in military organizations for future warfare, and suggest further research in this area.

This study is to develop a performance analysis model for SMEs.Based on similar performance indicators through previous studies, performance indicators for SMEs were rewritten.Through the Korean Journal Citation Index (KCI), 75 related data were classified and a comprehensive SME performance analysis model was developed.Performance analysis was divided into two axes and classified into tables.The horizontal axis is the spatial performance range, which is divided into three areas: performance management by department/function, integrated performance management for the entire organization, and governance performance management requiring policy feedback. The vertical axis is subdivided into short-term, mid-term, and long-term by time and growth stage, and is divided into three parts: technical performance according to technological input, economic performance as organizational performance, and social performance for policy utilization. Then, performance indicators were mapped to each column. As a result of the survey, 28% of technical performance was analyzed as a result of frequency analysis, and performance indicators were organized into five categories: IT, R&D, certification, patent, and innovation. Economic performance was divided into 29%, BSC, HRD, logistics, production quality management, financial support, asset management, etc. 6 categories, social performance 43%, ESG, marketing, export, policy support, consulting, cooperation, etc. 7 categories.Limitations of the study include the narrowness of the survey that derived only performance indicators despite being a meta-analysis, and the performance model was mapped and classified according to growth stage and support period.however Insufficiency of validity due to lack of evidence, performance indicators were developed, but there were limitations in utilization for practical use.

This study suggests a revised model of Lévi-Strauss' culinary triangle, which is frequently cited in food-related articles. To scrutinize how the media shares content about food and to remediate food discourse, this study conducted a focus group interview and targeted food program viewers and classified discoursal elements or nodes by Nvivo qualitative tools. In the process of classification, it found what seems to be hard to explain in the current food culture with Lévi-Strauss' culinary triangle, even if it still depicts appropriately, in the post-modern era implied complexity. Then, it arranged obtained discoursal nodes and analyzed the relationship between them. Interestingly, food in media plays as an important role beyond food itself, such as it can trigger memories, create social divides, play a role in economic invigoration, etc. Consequently, this paper suggests the revised culinary triangle model expanded from Lévi-Strauss' in which traces the molding process of food remediation with discoursal nodes in stages.

David Salle, born in Norman, Oklahoma in 1952, is the most important and controversial artist of the new-expressionist painting in the United States. His paintings are featured by unique artistic language, and extremely diverse and very ground-breaking expression, which reflect the American society at that time. Besides, he often uses complex image combination with striking colors and forms to attract and touch viewers. In this paper, based on the American new-expressionism, the painting language of David Salle's works was analysed, in which I found that it can be more intuitively and more profoundly feel the development of new-expressionist painting context and David Salle's particularity, and more clearly realize under what the characteristics of the era David Salle created the unique artistic language. The study on David Salle's unique painting language is of important research value and reference significance for our current artistic creation.

Art grows with the development of human civilization. Many art forms exist to connect the past and the future. Oil painting, a form of western painting, has flourished in China since its entry into China. In the continuous exploration of artistic language, Chinese artists have formed art forms with Chinese characteristics, permeated Chinese painting ideas and techniques, and formed specialized painting language. Through the oil painting works, the Chinese oriental aesthetic, national spirit, local customs and other times of humanistic features. As one of the many practitioners of oil painting in China, the author starts from the ego and continuously explores and studies in the practice of art. This paper mainly discusses the embodiment of Chinese oil painting modernity in the oriental art context and analyzes the spiritual temperament and painting materials, so as to expand the creative thinking of Chinese oil painting modernity in the oriental art context.

Chinese figure painting is the earliest type of painting to be mature in the history of Chinese painting. After its peak in the Jin and Tang dynasties, Chinese figure painting turned into a low tide in the Ming and Qing dynasties. Under the influence of the May Fourth New Culture Movement's concept of "introducing the Western culture into China", realistic ink wash figure painting emerged, which was different from traditional painting. Realistic ink wash figure painting is a new kind of painting that combines traditional Chinese painting methods with concepts of Western scientific painting. With the mutual reconciliation of realistic modeling and traditional Chinese painting, it makes up for the shortcomings of traditional Chinese figure painting in reproducing life, thus forming the diversified development of Chinese figure painting. Through an in-depth interpretation of the fusion of Chinese realistic ink figure painting with Chinese and Western, this paper accurately grasps the characteristics of the painting language, which is an important guide to the creation of Chinese realistic ink painting today.

The meticulous figure painting is one of the wonders of traditional Chinese painting and has blossomed in art history with its unique and interesting style. The period from the Warring States period to the Song and Yuan dynasties was a glorious period in its history, after which it tended to decline due to changes in painting materials and many socio-historical reasons. The extensive cultural exchanges in the world today, the penetration of Western values and the expansion of information technology have brought a huge impact on Chinese meticulous figure painting, which has developed an active way of thinking and expression after absorbing certain elements of Western culture and thought on the basis of inherited tradition. Contemporary Realistic Figure painters continue to explore new developments in meticulous figure painting in the contemporary context, and give contemporary meticulous figure painting a new cultural and ideological connotation, forming a new look that meets the requirements of the times, with richer and more lively content, subject matter and formal language. Traditional meticulous figure painting is characterised by a highly refined use of line and coloring composition. Contemporary meticulous figure painting focuses on the use of purely formal language and the expression of the personality of the creative subject, with a new outlook on the world of painting. In the contemporary multicultural context, new formal language and methods of expression are constantly being explored to create a new look. In the process of development, contemporary meticulous figure painting has merged the best qualities of traditional and contemporary culture, making it an art with a subtle language, rich in meaning and with the charm of the times and oriental characteristics. The author in the form of contemporary fine brushwork figure painting language as the research object, explore new form of fine brushwork figure painting, and in the contemporary society and multicultural context factors. Innovation, enrich and develop new forms of art language of contemporary social form and aesthetic temperament and interest.

The cultivation of preschoolers' mental health determines the future development of a person. Through the long-term practice of art teaching at the Longyuan Branch of the District Third Kindergarten of Guangxi, This paper summarizes some effective teaching methods to cultivate children's connection ability and sense of security through aesthetic education.Firstly, preschoolers' contact ability was studied, and the aspects such as the definition of contact ability and the reasons for the formation of contact ability were explored. Secondly, the development of preschoolers' sense of security, what to avoid in order to develop a good sense of security and the effects of security on children were investigated. Finally, several specific teaching cases were written based on these theories. Through these cases, aesthetic education was utilized to promote preschoolers' contact ability and develop a sense of security. The study mainly draws the following conclusions that if children want to have a successful career, a happy family in the future, it is crucial to have the ability of connect and security in childhood. Aesthetic education can promote the formation of children's ability of connection and security.Finally, I write specific teaching cases based on the above theories and practice, through which these cases use aesthetic education to promote the formation of children's contact ability and sense of security.

The ecological expression of art in modern society takes the harmonious developmental relationship between man and nature as an element and combines it with the various manifestations of painting as an expression of ecological artistic development. The necessary relationship for the harmonious development of nature is accurately articulated, and the ecological changes in people are expressed in integrated materials that inspire human reflection. In the pursuit of material pleasures, mankind is neglectful and indifferent to the environment. The development of composite painting in art and ecology is a process that more reveres the harmony between man and nature as well as satisfying the creative value of the work. After systematic evaluation and research, people have engaged in various structural forms of composite art painting development in the long history of art development, focusing on the integration of environmental and ecological culture. In the process of nature education going through development, the comprehensive practical development of nature education is enhanced and efforts are made to feel new ecological art ideas and new ways of valuing environmental protection. In this paper, an observational study of eco-art will be carried out, starting from the theory of hierarchical division and analyzing the contradictory relationship between man and nature. Recognize nature, understand it and feel it through eco-art painting. The analysis of the contradictory relationship between man and nature is combined with the identification of various types of information that give value to the environmental protection public, and the combination of ecological painting and nature art to achieve an upgrade of the environmental protection idea of the value of painting. In the development of artistic ecological comprehensive painting, it is necessary to put forward technical requirements and standards that meet the development of modern industry according to the characteristics and methods of ecological painting. The author of this paper discusses the necessity and social value of artistic ecological painting creation from the artist's point of view, expounds the practical achievements of ecological painting from the perspective of the history and present situation of the development of ecological aesthetics at home and abroad, and gives the concept and creative method of contemporary art comprehensive material painting in combination with his own actual situation.

Watercolour painting was introduced to China over a hundred years ago, and in the last two decades, it has developed rapidly, presenting a situation of diversified development. While Western-style watercolour painting has been adopted by Chinese painters, they have also expanded on it with their own aesthetic awareness and cognitive styles. As a result, Chinese watercolour painting has developed a set of expressive techniques that highlight the cultural characteristics of the nation in terms of aesthetics, concepts and techniques, resulting in a painting style with a distinctive national personality at present. Although Chinese watercolour painting has taken on a variety of styles with the intervention of modern and contemporary art, realistic watercolour painting is still the mainstream. However, there are obvious differences between the "realism" of Chinese watercolour painting and the "realism" of Western watercolour painting in terms of expression. The most distinctive feature is the "imagery" language of expression, which is closely linked to the cultural heritage of Chinese tradition and is of great value for research. I interpret the aesthetics, composition, colour and brushwork of Chinese realistic watercolour painting from the perspective of traditional Chinese aesthetics in order to deepen the understanding of Chinese realistic watercolour painting and to provide a reference for the further development of the art of Chinese realistic watercolour painting.

Chinese traditional patterns, which are part of our national precious heritage, have a long history. Tiger culture plays a very important role in folk art. In modern society, it is a symbol of human spirit and morality. The tiger pattern is also a unique traditional pattern in Chinese folklore. From the Spring and Autumn period to modern society, the tiger pattern has evolved in form through thousands of years of development. It is also a representative intangible cultural heritage in contemporary times. It plays a special role in the cultural exchange of different regions, resulting in the generation of the creation of folk art with great local characteristics. Therefore, traditional tiger patterns are an important part of traditional Chinese folk culture and art. In this study, by analyzing the development and evolution history of Chinese traditional tiger patterns, the application methods of Chinese traditional tiger patterns were summarized, the rich cultural connotation, artistic characteristics and application of traditional tiger pattern in modern fashion design were discussed. In contemporary design, the new and improved tiger pattern styles were explored, intangible cultural heritage was interpreted and inherited, and the cultural and artistic values contained therein were extracted. The author combined with modern fashion design, according to people's aesthetic taste and design principles, it is recreated,so that the traditional pattern has certain characteristics of The Times.But at the same time it retains its original character,and the traditional tiger pattern was inherited and the cultural connotation of clothing design was enriched.

Zhang Yu was a famous Taoist priest and poet in Yuan Dynasty, compared with the identity of Taoist and poet, his handwriting had greater influence in history. According to the relevant historical data, people at that time were mainly attracted by his Taoist identity and poetic talent. However, if we considered him as a poet,or a calligrapher to inspect,it would be often easier than facing a Taoist priest. Zhang Yu's poems and relationships can be used as some clues for our investigation of his calligraphy activities,not only would it not affect us to judge the value of his calligraphy, but also we will comprehensively and objectively analyze his calligraphy works. His early calligraphy closely followed Zhao Mengfu, in his later years, when he met Yang Weizhen, the style of writing changed greatly.During this period, what kind of changes and fundamental influence had on Zhang Yu's life and book learning thoughts experienced. Our contributions to this paper are as follows.To solve this issue,this passage will try to find clues from several representative figures and representative calligraphy works of Zhang Yu, and draw on the research results of relevant scholars to discuss the identity of Zhang Yu as a Taoist priest and the origin and style characteristics of his handwriting and probed into the status and influence of his calligraphy in history.

The government has defined domestic violence as one of the four major social evils and tried to prepare laws and systems to prevent it. Nevertheless, domestic violence has emerged as a serious social issue, and compare to the number of domestic violence cases that are constantly increasing, the report rate of domestic violence is significantly lower. This suggests the need to improve citizens' perception of domestic violence as the issue to solve it together in society, not as a private matter at home. Most of existing contents for preventing domestic violence and improving awareness are simple viewing forms of video contents, which have little effect on recognition. We aim to confirm the possibility of improving social awareness about domestic violence by producing Virtual Reality (VR) contents that have great features of user's immersion and empathy. In this VR content, the user can interact with various objects in the virtual reality of domestic violence and directly or indirectly experience the victim's position. Users who view the violent environment from the victim's point of view can have a subjective empathy for the problem, which is expected to induce more active awareness about domestic violence.

IoT technology application has been part of modern people's everyday life. This technology makes people to depend on smart devices. 'Smartphone' is the most typical example. Despite the advantages given by this device, the bad side effects are also notable. This paper presents interactive content on the dependence of smartphone device. The research objective is to make individuals to reduce the use of smartphones by realizing their own problems of smartphone dependency. Research was progressed by analyzing aspects obtained from users participating in the self-developed interactive game contents. As a result of the analysis, approximately 68% of people were aware of the problem through this content. This indicates the potential of using convergence research in interactive contents with other fields furthermore.

The global warming by greenhouse gases causes climate change and disasters such as earthquakes and tsunamis frequently, leading to great damage. It is important to build efficient and scalable disaster response services to minimize the damage. Existing disaster warning service by the mobile text is limited by the scalability and the data size to be delivered. In this paper, we propose a framework for disaster response services that is efficient and flexible by allowing to adopt various indexing schemes and scalable by supporting any number of clients in disaster situations anytime and anywhere. Also, the framework by wireless data broadcast can be free from the limitation of the size of data to be delivered. We design and implement the proposed framework and evaluate the framework. For the evaluation, we simulate the implemented framework by adopting various indexing schemes like HCI, DSI and TTSI, and by comparing the access times of the clients. Through the evaluation, we show that the proposed framework can provide efficient and scalable and flexible disaster response services.

The purpose of this study is to measure and compare the balance of motion between the left and right using a wearable sensor during upper limb exercise using an exercise equipment. Eight participants were asked to perform upper limb exercise using exercise equipment, and exercise data were measured through IMU sensors attached to both wrists. As a result of the PCA test, Euler Yaw(Left: 0.65, Right: 0.75), Roll(Left: 0.72, Right: 0.58), and Gyro X(Left: 0.64, Right: 0.63) were identified as the main components in the Butterfly exercise, and Euler Pitch(Left: 0.70, Right 0.70) and Gyro Z(Left: 0.70, Right: 0.71) were identified as the main components in the Lat pull down exercise. As a result of the Paired-T test of the Euler value, Yaw's Peak to Peak at Butterfly exercise and Roll's Mean, Yaw's Mean and Period at Lat pull down exercise were smaller than the significance level of 0.05, proving meaningful difference was found. In the Symmetry Index and Symmetry Ratio analysis, 89% of the subjects showed a tendency of dominant limb maintaining relatively higher angular movement performance then non-dominant limb as the Butterfly exercise proceeds. 62.5% of the subjects showed the same tendency during the Lat pull down exercise. These experimental results indicate that meaningful difference at balance of motion was found according to an increase in number of exercise trials.

As digital advertising continues to dominate the advertising industry and experience substantial growth, associated criminal activities such as advertising fraud and brand safety risks have become increasingly prevalent. Despite the severity and extent of these crimes, the response in Korea has been lackluster, often perceiving them merely as losses in advertising expenses incurred by corporations. However, it is important to note that these issues have direct repercussions on the end-consumer in the form of increased prices for goods and services. Furthermore, illegal and intrusive advertisements not only cause inconvenience to the viewer, but may also indiscriminately target cognitively vulnerable groups, such as children and the elderly, with the intention of manipulating advertising metrics and artificially inflating performance indicators. In this study, we aim to explore the concept and significance of advertising fraud and brand safety, and to evaluate the current measures taken in the Korean market. Additionally, we will delve into the implications of related policies and emphasize the necessity of digital advertising literacy in addressing these issues.

This study aims to enhance the engineering education for non-majors by incorporating the concept of Global Citizenship Education and addressing the need for education that responds to climate and ecological changes. The study uses robot programming as a tool to foster the development of global citizens. Non-majors often struggle with producing more than just motionless forms or solid productions, due to a lack of understanding of mechanisms and coding. The study proposes the use of the Convergence D-SteamRobot (DSR) to address this issue by blending humanities and engineering. This is achieved by presenting problems through books to increase empathy, integrating simple machine mechanisms, and creating prototypes to solve self-defined problems. Through this process, learners determine the SDGs topic they want to solve and learn about the simple mechanical mechanism involved in producing the prototype. The educational model provides a constructivist learning environment that emphasizes empathy and exploration, encourages peer-learning, and improves divergent thinking and problem-solving skills.

As urbanization accelerates and facilities that use energy increase, human life and property damage due to fire is increasing. Therefore, a fire monitoring system capable of quickly detecting a fire is required to reduce economic loss and human damage caused by a fire. In this study, we aim to develop an improved artificial intelligence model that can increase the accuracy of low fire alarms by mixing DeepSORT, which has strengths in object tracking, with the YOLOv5s model. In order to develop a fire detection model that is faster and more accurate than the existing artificial intelligence model, DeepSORT, a technology that complements and extends SORT as one of the most widely used frameworks for object tracking and YOLOv5s model, was selected and a mixed model was used and compared with the YOLOv5s model. As the final research result of this paper, the accuracy of YOLOv5s model was 96.3% and the number of frames per second was 30, and the YOLOv5s_DeepSORT mixed model was 0.9% higher in accuracy than YOLOv5s with an accuracy of 97.2% and number of frames per second: 30.

In this paper, we propose a mixed neural network structure of CNN and LSTM that can be used to detect or predict odor occurrence, which is most required in manufacturing industry or real life, using odor complex sensors. In addition, the proposed learning model uses a complex odor sensor to receive four types of data such as hydrogen sulfide, ammonia, benzene, and toluene in real time, and applies this data to an inference model to detect and predict odor conditions. The proposed model evaluated the prediction accuracy of the learning model through performance indicators according to accuracy, and the evaluation result showed an average performance of 94% or more.

This study surveyed the island located in Sinan-gun and Wando-gun four times, once per season from September 2020 to November 2021 in order to understand the distribution of waterbirds on the island of the southwest coast. As a result of the investigation, a total of waterbirds of 7 orders, 12 families of 50 species, and 3,680 individuals were identified. By taxon, the largest number of species were identified as 11 species of waders, and the number of ducks was the largest with 2,035 individuals. In Bigeum-do Island, where forests are distributed less, the proportion of farmland is large, and tidal flats are widely distributed, the largest number of species and individuals of herons and waders were identified. Ducks and gulls have also been identified in large numbers of individuals in Bigeum-do Island. Most of them are forests and farmland, and the largest number of species and individuals of ducks have been identified in Pyeongil-do Island, where the coast is deep. In addition, Nodae-do Island, Sobyeongpung-do, and Daebyeongpung-do Island with monotonous habitats have been identified with fewer species and individuals. As a result, We learned that various types of waterbirds lived in islands with various habitats, and that the preferred habitat was different depending on the characteristics of the taxon group. By season, the largest number of species was identified as 35 in autumn, and the largest number of individuals was identified as 1,681 in winter. Although most of the seasonally identified waterbirds were winter birds, the largest number of species were identified in autumn, and most of the confirmed waterbird migration were identified in the autumn, indicating that waterbirds used the west-south coast islands as an intermediate stopover while traveling.

Identifying the distribution of species and specific factors related to it is very important because it is habitat conservation that is greatly linked not only to ecological research but also to human health. After all, protecting each one's habitat will protect wildlife and further maintain a healthy ecosystem. Therefore, in this study, data were collected, compared, and analyzed through existing studies and field-oriented surveys. The results of the survey confirmed high species diversity in agricultural areas and forest areas that can reduce moisture supply and moisture loss, and the non-segmental environment, that is, ecological connectivity, was largely influenced by amphibian species diversity. It was confirmed that the non-fragmented environment, that is, ecological connectivity, was greatly affected by amphibian species diversity. In addition, the three factors that affect amphibian survival are: It was identified as the effect of not establishing a buffer space, the effect on the ecological transformation around the habitat during the summer rainy season, and the effect on the disconnected ecological environment.

In this study, to check the function of managing the severity of ultraviolet rays with a smart watch, a popular health care IT device, It was tested whether measuring heart rate using a PPG(Photoplethysmography) sensor representatively used in a smart watch could tell skin changes caused by ultraviolet rays. Through this experiment, we examined the possibility that the skin color tanned by ultraviolet rays can be determined only by the heart rate measurement function of the PPG sensor. In addition, the possibility of expanding the heart rate measurement function of the PPG sensor to the use of skin condition management was considered. we used an Arduino-based reflective PPG sensor to measure changes in heart rate by selecting body sites with high and low UV rays exposure. A significant value was derived through tests considering factors such as gender, UV exposure, and age. As a result, the study identified the possibility of adding ultraviolet rays and skincare items to future smart watch healthcare items and the possibility of expanding skin measurement methods. It is also possible to suggest the direction of future research.

As we enter a super-aged society, studies are being conducted to reduce complications and deaths caused by falls in elderly adults. Research is being conducted on interventions for preventing falls in the elderly, wearable devices for detecting falls, and methods for improving the performance of fall detection algorithms. Wearable devices for detecting falls of the elderly generally use gyro sensors. In addition, to improve the performance of the fall detection algorithm, an artificial intelligence algorithm is applied to the x, y, z coordinate data collected from the gyro sensor. In this paper, we develop a wearable device that uses a gyro sensor, body temperature, and heart rate sensor for health management as well as fall detection for the elderly. In addition, we develop a fall detection and health management system that works with wearable devices and a guardian's mobile app to improve the performance of the fall detection algorithm and provide health information to guardians.

After a longitudinal analysis of the data on the college entrance examination of students enrolled in the Department of Chemistry Education at Gyeongnam from 2014 to 2021, the effect on the academic achievement of general chemistry according to the type of college entrance examination was studied. And the impact on the academic achievement of general chemistry according to the type of admission screening in face-to-face and non-face-to-face teaching-learning was also studied. As a result of analyzing the academic achievement of general chemistry by admission process, students admitted through occasional screening showed relatively high grades of A and B at 88.7%, and the ratio of grades of 1~3 of chemistry I in high school was high. On the other hand, in the case of students admitted through regular admission, the ratio of grades of A and B in general chemistry was very high at 94.3%, and the ratio of grades of 3~4 in chemistry I of the College Scholastic Ability Test was high. As a result of analyzing the academic achievement of general chemistry by class type and admission process, it was found that the grades of chemistry I by face-to-face classes had an effect on the academic achievement of general chemistry in non-face-to-face classes. In both admissions, the academic achievement of general chemistry by face-to-face classes was relatively higher than that of non-face-to-face-to-face classes.
