Purposes: This research is conducted to identify main features and trends of mission, vision and core values in Korean tertiary general hospitals by using text-mining. Methodology: For the study, 45 mission, 112 vision and 190 core values are collected from 45 tertiary general hospitals' homepages in 2022 and use word frequency analysis and Leyword co-occurrence analysis. Findings: In the tertiary general hospitals' mission, there are high frequency words such as 'health', 'humanity', 'medical treatment', 'education', 'research', 'happiness', 'love', 'best', 'spirit', and mission mainly includes the content of contributing humanity's health and happiness with these words. In case of vision, high frequency words are 'hospital', 'medical treatment', 'research', 'lead', 'trust', 'centered', 'patient', 'best', 'future'. By using these words in vision, it represents the definition and characteristics of vision such as ideal organizations in the future, goals and targets. As a result of the Leyword co-occurrence analysis, vision includes the content of 'high-tech medical treatment', 'special care for patients', 'leading education and research', 'the highest trust with customer', 'creative talents training'. -astly, the high frequency word-pairs in core values are 'social distribution', 'innovation pursuit', 'cooperation and harmony', and it defines standards of behavior for organizations. Practical Implication: To correct the problems of vision, mission and core values from findings, firstly, it needs for Korean tertiary general hospitals to use the words that can explain organization's identity and differentiate others in their mission. Secondly, considering strengthening the role of hospitals in their community and the importance of members in organizations, it is necessary to establish vision with considering community and members to activate vision effectively. Thirdly, because there are no specific guidelines of establishing mission, vision and core values for healthcare organizations, this research concepts and results could be utilized when other organizations establish mission, vision and core values.

Objectives: Disability weights require regular updates, as they are influenced by both diseases and societal perceptions. Consequently, it is necessary to develop an up-to-date list of the causes of diseases and establish a survey panel for estimating disability weights. Accordingly, this study was conducted to calculate, assess, modify, and validate disability weights suitable for Korea, accounting for its cultural and social characteristics. Methods: The 380 causes of disease used in the survey were derived from the 2019 Global Burden of Disease Collaborative Network and from 2019 and 2020 Korean studies on disability weights for causes of disease. Disability weights were reanalyzed by integrating the findings of an earlier survey on disability weights in Korea with those of the additional survey conducted in this study. The responses were transformed into paired comparisons and analyzed using probit regression analysis. Coefficients for the causes of disease were converted into predicted probabilities, and disability weights in 2 models (model 1 and 2) were rescaled using a normal distribution and the natural logarithm, respectively. Results: The mean values for the 380 causes of disease in models 1 and 2 were 0.488 and 0.369, respectively. Both models exhibited the same order of disability weights. The disability weights for the 300 causes of disease present in both the current and 2019 studies demonstrated a Pearson correlation coefficient of 0.994 (p=0.001 for both models). This study presents a detailed add-on approach for calculating disability weights. Conclusions: This method can be employed in other countries to obtain timely disability weight estimations.

The utilization of department information in bibliometric analysis using scientific and technological literature is highly advantageous. In this paper, the department information dataset was built through the screening, data refinement, and classification processing of authors' department type belonging to university institutions appearing in academic journals in the field of science and technology published in Korea, and the automatic classification model based on deep learning was developed using the department information dataset as learning data and verification data. In addition, we analyzed the co-authorship structure and network in the field of computer science using the department information dataset and affiliation information of authors from domestic academic journals. The research resulted in a 98.6% accuracy rate for the automatic classification model using Korean department information. Moreover, the co-authorship patterns of Korean researchers in the computer science and engineering field, along with the characteristics and centralities of the co-author network based on institution type, region, institution, and department type, were identified in detail and visually presented on a map.

With the development of networks and the increase in the number of network devices, the number of cyber attacks targeting them is also increasing. Since these cyber-attacks aim to steal important information and destroy systems, it is necessary to minimize social and economic damage through early detection and rapid response. Many studies using machine learning (ML) and artificial intelligence (AI) have been conducted, among which payload learning is one of the most intuitive and effective methods to detect malicious behavior. In this study, we propose a preprocessing method to maximize the performance of the model when learning the payload in term units. The proposed method constructs a high-quality learning data set by eliminating unnecessary noise (stopwords) and preserving important features in consideration of the machine language and natural language characteristics of the packet payload. Our method consists of three steps: Preserving significant special characters, Generating a stopword list, and Class label refinement. By processing packets of various and complex structures based on these three processes, it is possible to make high-quality training data that can be helpful to build high-performance ML/AI models for security monitoring. We prove the effectiveness of the proposed method by comparing the performance of the AI model to which the proposed method is applied and not. Forthermore, by evaluating the performance of the AI model applied proposed method in the real-world Security Operating Center (SOC) environment with live network traffic, we demonstrate the applicability of the our method to the real environment.

Recently, constructing the database of road network is a main key in various social operation as like the transportation, management, security, disaster assesment, and the city plan in our life. However it need high expenses for constructing the data, and relies on many people for finishing the tasks. This study proposed the classification method for discriminating between the road and building points using the entropy theory, then detects the classes as a expecting road from the classified point group using the standard reflectance intensity of road and the characteristics restricted by raw. Hence the main object of this study is to develop a method which can detect the road in urban area using only the LiDAR data.

The purpose of this study was to analyze evaluation variables of service quality of Korean restaurant especially focused on cold noodle restaurants(CNR). The data were analyzed about customer’s expectation of food service quality, service quality was improved by employee’s service in restaurant and employee education in the focus on CNR. The survey was carried out 423 customers and 50 employees in Seoul and Kyunggi province. All statistical data analyses were conducted using the Statistical Package for the Social Science(SPSS version 10.0). The consumer’s evaluation score of service quality were significantly different by consumer’s characteristics. The well planned service at CNR must be developed according to consumer variables such as sex and age group. The evaluation score of service quality were not significantly different by seasonal variation and consumer’s menu selection. The evaluation score of service qualities in CNR were significantly different between customer variables with employees variables. All of the evaluation points of service quality in employees were significantly higher than customers. This result was show that well-trained employees were important factors in consumer satisfaction. Through the employee education program, consumer oriented service mind mort be to developed in employees and employees’ recognition about the importance of service increased the satisfaction of customer using CNR.

The intergenerational support exchange depends on elder's objective conditions and social context, and its effects are diverse. I argue that not only capacity such as health condition and economic status but also relational properties among parent(s) and adult children are important to determine their reciprocal support exchange. Seoul area is selected, and 730 elders are interviewed to be analyzed quantitatively. The survey data are collected based on the structured questionnaire. Findings are partly supportive to the arguments presented above. The relational properties, especially coresidence, the number of adult children, and contact frequency independently influence reciprocal support. The better health conditions of parent(s) are, the more support to adult children is given. The economic status is related to financial support exchange only. The types of intergenerational support exchange include dependant, balanced, and generalized reciprocity. The most important determinant of the reciprocity is the elders' health condition.

As for the various pathological phenomena of the society which is getting worse without any improvement, the film paints the phenomenon nakedly with the cold and cynical gaze on the basis of realism. These attempts originated in the Chinese art world, and they cynically sketched a Chinese society that lost hope after 6·4. The cynicism of the art world contains meanings such as instruction, meanness, passion, indifference, and mockery. In particular, the distrust of the social system after 6·4 and the collapse of the Soviet and Eastern European socialist nations gave the Chinese people a skeptical view of socialism. This situation of the times has a cynical viewpoint to face as it is instead of prudent criticism. This cynical view was embraced by filmmakers who were not silent on The pathological phenomenon of society, and they were directed to films. is a film about the love, separation, suicide, frustration and reconciliation of youth in the era of identity confusion after 6·4. The characters in the film did not mention a single word about the state power that made them do it. based on the characteristics of women in northeast China and the murder that occurred around a woman with a beauty that was not like a laundry employee. Centered around the unresolved slice murder case, expressed human moral ambiguity that does not distinguish good fortune from human instinct for struggle for survival, and portrayed the scenery of a very cold northeast small city. But it does not show any criticism of the crime. Based on the true story of the 2000s, the portrays the uncomfortable aspects of China that established Chinese socialism. A film composed of four short episodes conveys the destiny set by God.
