This study attempted to investigate the effects of experience of non-contact lectures on learning flow against college students majoring in cosmetology and provide basic data to beauty education industry in the with-COVID-19 era. For this, a self-administered questionnaire survey was performed against 300 college students majoring in cosmetology from June 7 to 21, 2022. A total of 286 copies were collected and used for final analysis. The collected data were analyzed by frequency analysis, factor analysis, exploratory factor analysis, descriptive statistics, correlation analysis and multiple regression analysis, using SPSS 21.0, and the results found the followings: According to analysis of non-contact lecture experience factors, two course satisfaction factors were obtained. In learning flow, learning pleasure and learning flow were found. Specifically, class activities had a positive influence on 'learning pleasure (𝛽=.279, p<.007)' and 'learning flow (𝛽=.221, p<.031)' with statistical significance (p<.05). In addition, course satisfaction revealed a positive effect on 'learning flow (𝛽=.223, p<.041)' with statistical significance (p<.05). The above results confirm that experience of non-contact lectures affects learning flow. Therefore, it is anticipated that there would be more efforts to seek an efficient non-contact learning plan in this new era.

This study developed and evaluated a safe route guidance service for electric personal assistive mobility device used mainly by the mobility impaired people to improve their mobility. Thirteen underlying factors affecting the mobility of electric personal assistive mobility device have been derived through a survey with the mobility impaired people and employees in related organizations in Busan Metropolitan City. After assigning safety scores to individual factors and identifying the relevant factors along routes of interest with an object detection AI model, the safe route for electric personal assistive mobility device was provided through an optimal path-finding algorithm. As a result of comparing the general route of T-map and the recommended route of this study for the identical routes, the latter had relatively fewer obstacles and the gentler slope than the former, implicating that the recommended route is safer than the general one. As future works, it is necessary to enhance the function of a route guidance service based on the real-time location of users and to conduct spot investigations to evaluate and verify its social acceptability.

The present study aims to explore the causes of employment difficulty on the basis of job applicant's interest from P-E (person-environment) fit perspective. Our approach relied on a textual analytic method to reveal insights from their situational interests in a job search during the change of labor market. Thus, to investigate the type of major interests and psychological responses, user-generated texts in a social community were collected for analysis between January 1, 2013 through December 31, 2015 by crawling the online-community in regard to job seeking and sharing information and opinions. The results of topic analysis indicated user's primary interests were divided into four types: perception of vocation expectation, employment pre-preparation behaviors, perception of labor market, and job-seeking stress. Specially, job applicants put mainly concerns of monetary reward and a form of employment, rather than their work values or career exploration, thus youth job applicants expressed their psychological responses using contextualized language (e.g., slang, vulgarisms) for projecting their unstable state under uncertainty in response to environmental changes. Additionally, they have perceived activities in the restricted preparation (e.g., certification, English exam) as determinant factors for success in employment and suffered form job-seeking stress. On the basis of these findings, current unemployment matters are totally attributed to the absence of pursing the value of vocation and job in individuals, organizations, and society. Concretely, job seekers are preoccupied with occupational prestige in social aspect and have undecided vocational value. On the other hand, most companies have no perception of the importance of human resources and have overlooked the needs for proper work environment development in respect of stimulating individual motivation. The attempt in this study to reinterpret the effect of environment as for classifying job applicant's interests in reference to linguistic and psychological theories not only helps conduct a more comprehensive meaning for understanding social matters, but guides new directions for future research on job applicant's psychological factors (e.g., attitudes, motivation) using topic analysis.

시각이 아닌 오감체계에 관계하는 때문에 현대미술은 외관만으로 이루어지지 않는다. 곧 예술 작품들은 하나의 장소를 관객에게 제공하여, 심리적, 물리적, 또는 예술이 존재여부에 관한 갖가지 질문들을 제기한다. 모든 예술 작품은 메시지를 담고 있다. 이러한 관점에서 개념 또는 아이디어에 우선하는 현대미술은 그들의 메시지를 전달하기 위해 우리의 사회적 배경과 보편성을 간과할 수 없다. 우리의 물체 인식은 결국 우리의 경험체계를 통해서 이루어진다고 간주하면, 현대미술의 새로운 형태는 보편적 특질들이 그 특질들 이상의 상태로 보여지도록 유도한다. 이러한 창조 행위의 시작은 현대인간의 문화 읽기이며 문화는 인간과 자연의 긴밀한 관계 속에서 이루어진다. 역사는 지나간 시간을 기록한 것이며, 이 또한 우리의 지식과 정보 체계에 속한다. 회화가 평면에 입체감을 표현하는 것과는 달리 조각은 자연 속, 즉 실재공간 속에 있는 모든 것을 표현하기 때문에 시각(visible) 이외에도 촉각(tangible)이 관여하게 된다. 조각의 특수성은 촉각(tangible)이 우선하는 것이다. 그러나 시각과 촉각은 매우 적극적으로 미학적 경험에 참여하는 감각으로 이들을 서로 분리하여 생각하기가 무척 힘들다. 왜냐하면 어떤 경험에 있어서 기억연합 또는 감각 연합에 의해 하나의 감각이 다른 여러 감각을 촉발하여 연쇄반응 혹은 '형태 Gestalt'를 이루기 때문이다. 대부분의 근대 조각 작품들은 조각대 위에 고정되어 있는 구상 형태를 지녔기 때문에 조각작품 자체가 지닌 외적 형태와 그 자체내의 공간이 더욱 중요한 역할을 하게 된다. 말하자면 미로의 비너스 조각은 대리석과 비너스 형태의 결합이다. 때문에 관객은 그 주변을 돌면서 우리 신체의 내적 공간과 시각에 의존하면서 그 작품의 중량감, 양감, 형태 등의 특질과 만나게 된다. 그러나 현대 추상조각과 개념조각은 이보다 좀 더 확장된 공간을 제시한다. 이것은 현대조각이 건축개념을 수용한 때문이며, 그것이 때로는 안 쪽에서 때로는 바깥 쪽에서 그 형태를 결정하며, 보고 듣고 느끼고 만져지고 왕래하는 등의 인식 영역인 관객의 오감체계에 직접적으로 관계하기 때문이다. 우리는 건축 공간에서, 시각 외에도 청각이나 촉각을 통해 지각한다. 대강 요약하자면 공간은 객관적 상태이기보다는 인식영역의 주관성을 통해 받아들여진 우리가 지나쳐온 것들이나 체험된 공간이다. 여기서 '받아들여지는' 일은 과거 경험들의 주체들, 언어와 문화에 의해서 이루어져야 한다. 건물, 즉 둘러싸고 있는 공간은 중앙이 아니다. 중앙은 바로 나, 둘러싸여진 나이다 나는 나의 동작에 따라 그 공간의 시스템을 변화시킬 수 있는 유동적인 중심이다 (이때의 나는 위치의 축을 변화시키는 것이 아니라, 그들을 탐색하는 것이다). 작품이 대형화되면서 이러한 건축공간개념이 현대 조각가들의 작품개념에 이용되었다고 본다. 현대미술에서 In situ작업과 특정한 장소를 위한 기획되어진 최근의 프로젝트 작업들은 대형화되어있으며, 건축에서처럼 특정한 장소를 만들어낸다. 로잘린드 크라우스(Rosalind Krauss)는 또한 '조각영역의 확장 (La sculpture dans le champ elargi)'에서 현대조각이 건축과 환경의 영역을 침범하고 있음을 지적한다. 그녀에 의하면, 1960년대 이후의 현대조각은 이러한 탈 귀속성과 조각의 자율성을 획득함으로써 조각은 건축물이 아니면서 건축물 주변에 위치하거나 풍경이 아니면서 풍경 안에 자리잡게 되었다. 이와 같이 현대의 대형조각 작품들 - 예를 들어 대형화된 미니별 조각이나 개념미술, 또는 대지예술 등 -은 풍경의 실재가 아니기 때문에 환경으로부터 구분된다고 언급하고 있다. 이들 조각은 더 이상 만져지는 실체이거나 점유하는 공간의 상징언어를 지닌 조각의 범주에 한정되지 않게 된다. 조각과 건축의 공간인식을 인체의 크기와 관련하여 보면, 메를로 퐁티(Merleau-Ponty)의 '지각의 현상학' 은 우리가 논하는 작품의 공간체계를 분석하는데 지침표가 되어준다. 메를로 퐁티가 말하는 지각은 정신에 의해서만 이루어지는 것이 아니며, 몸과 함께 이루어지는 현상이다. 지각은 우리가 부단히 눈을 움직이고 만지고 냄새를 맡고 주변을 돌아 다니면서 세계와의 직접적인 접촉을 통해 이루어 진다. 몸의 움직임을 통하여 나타나는 신체적 표현은 몸 자체가 원천적으로 지향적 활동의 주체로서 파악되는 한 이미 항상(恒常, constant) 의미 현상을 지니다. 우리의 지각이 움직이는 몸의 지향 활동을 통해 이루어진다는 것은 우리의 몸의 지향활동이 의식에 선행함을 의미한다. 몸의 움직임은 의식의 의도를 표현할 때에만 의미를 나타내는 기호가 되는 것이 아니라, 이미 그 자체가 살아있는 표현이다. 우리의 몸짓, 표정은 우리 의식이 의도하기 전에 이미 의미가 담겨있다. 몸은 그 자체가 기호(Signe)적이다. 결국. 메를로 퐁티에게서 세상(le monde entier)은 그 자신이 주체가 되어 인식한다, 그리고 이 인식 구조에는 우리의 몸이 구심점(le point centripete)이 된다. 만약 우리가 이러한 메를로 퐁티의 개념을 염두에 둔다면, 예술작품의 특성에 매우 중요한 역할을 하고 있는 재료와 크기를 이해할 수 있을 것이다.

This study analyzed the frequency and level of scientific practices presented in secondary science textbooks. A total of 1,378 student activities presented in 14 middle school science textbooks and 5 high school integrated science textbooks were analyzed, using the definition and level of scientific practice suggested in the NGSS. Findings show that most student activities focus on three practices. Compared to the textbooks for the previous science curriculum, the practice of 'obtaining, evaluating, and communicating information' was more emphasized, reflecting societal changes due to ICT development. However, the practice of 'asking a question', which can be an important element of student-led science learning, was still rarely found in textbooks, and 'developing and using models', 'using math and computational thinking' and 'arguing based on evidence' were not addressed much. The practices were mostly elementary school level except for the practice of 'constructing explanations'. Such repeated exposures to a few and low level of practices mean that many future citizens would be led to a naïve understanding of science. The findings imply that it is necessary to emphasize various practices tailored to the level of students. In the upcoming revision of the science curriculum, it is necessary to provide the definition of practices that are not currently specified and the expected level of each practice so that the curriculum can provide sufficient guidance for textbook writing. These efforts should be supported by benchmarking of overseas science curriculum and research that explore students' ability and teachers' understanding of scientific practices.

It is important to preempt new technology because the technology competition is getting much tougher. Stakeholders conduct exploration activities continuously for new technology preoccupancy at the right time. Gartner's Hype Cycle has significant implications for stakeholders. The Hype Cycle is a expectation graph for new technologies which is combining the technology life cycle (S-curve) with the Hype Level. Stakeholders such as R&D investor, CTO(Chef of Technology Officer) and technical personnel are very interested in Gartner's Hype Cycle for new technologies. Because high expectation for new technologies can bring opportunities to maintain investment by securing the legitimacy of R&D investment. However, contrary to the high interest of the industry, the preceding researches faced with limitations aspect of empirical method and source data(news, academic papers, search traffic, patent etc.). In this study, we focused on two research questions. The first research question was 'Is there a difference in the characteristics of the network structure at each stage of the hype cycle?'. To confirm the first research question, the structural characteristics of each stage were confirmed through the component cohesion size. The second research question is 'Is there a pattern of diffusion at each stage of the hype cycle?'. This research question was to be solved through centralization index and network density. The centralization index is a concept of variance, and a higher centralization index means that a small number of nodes are centered in the network. Concentration of a small number of nodes means a star network structure. In the network structure, the star network structure is a centralized structure and shows better diffusion performance than a decentralized network (circle structure). Because the nodes which are the center of information transfer can judge useful information and deliver it to other nodes the fastest. So we confirmed the out-degree centralization index and in-degree centralization index for each stage. For this purpose, we confirmed the structural features of the community and the expectation diffusion patterns using Social Network Serice(SNS) data in 'Gartner Hype Cycle for Artificial Intelligence, 2021'. Twitter data for 30 technologies (excluding four technologies) listed in 'Gartner Hype Cycle for Artificial Intelligence, 2021' were analyzed. Analysis was performed using R program (4.1.1 ver) and Cyram Netminer. From October 31, 2021 to November 9, 2021, 6,766 tweets were searched through the Twitter API, and converting the relationship user's tweet(Source) and user's retweets (Target). As a result, 4,124 edgelists were analyzed. As a reult of the study, we confirmed the structural features and diffusion patterns through analyze the component cohesion size and degree centralization and density. Through this study, we confirmed that the groups of each stage increased number of components as time passed and the density decreased. Also 'Innovation Trigger' which is a group interested in new technologies as a early adopter in the innovation diffusion theory had high out-degree centralization index and the others had higher in-degree centralization index than out-degree. It can be inferred that 'Innovation Trigger' group has the biggest influence, and the diffusion will gradually slow down from the subsequent groups. In this study, network analysis was conducted using social network service data unlike methods of the precedent researches. This is significant in that it provided an idea to expand the method of analysis when analyzing Gartner's hype cycle in the future. In addition, the fact that the innovation diffusion theory was applied to the Gartner's hype cycle's stage in artificial intelligence can be evaluated positively because the Gartner hype cycle has been repeatedly discussed as a theoretical weakness. Also it is expected that this study will provide a new perspective on decision-making on technology investment to stakeholdes.

Crime occurs differently based on not only place locations and building uses but also the characteristics of the people who use the place and the spatial structures of the buildings and locations. Therefore, if spatial big data, which contain spatial and regional properties, can be utilized, proper crime prevention measures can be enacted. Recently, with the advent of big data and the revolutionary intelligent information era, predictive policing has emerged as a new paradigm for police activities. Based on 7420 actual crime incidents occurring over three years in a typical provincial city, "J city," this study identified the areas in which crimes occurred and predicted risky areas. Spatial regression analysis was performed using spatial big data about only physical and environmental variables. Based on the results, using the street width, average number of building floors, building coverage ratio, the type of use of the first floor (Type II neighborhood living facility, commercial facility, pleasure use, or residential use), this study established a Crime Incident Prediction Model (CIPM) based on Bayesian probability theory. As a result, it was found that the model was suitable for crime prediction because the overlap analysis with the actual crime areas and the receiver operating characteristic curve (Roc curve), which evaluated the accuracy of the model, showed an area under the curve (AUC) value of 0.8. It was also found that a block where the commercial and entertainment facilities were concentrated, a block where the number of building floors is high, and a block where the commercial, entertainment, residential facilities are mixed are high-risk areas. This study provides a meaningful step forward to the development of a crime prediction model, unlike previous studies that explored the spatial distribution of crime and the factors influencing crime occurrence.

The purpose of this study was to analyze how consumers make links between convenience meat products and self-relevant consequences and value. Surveys on convenience meat product consumption patterns and hard laddering based on means-end chain theory were conducted from April 21 to April 25, 2014 and targeted 200 consumers in the US. The most preferred cooking method of convenience meat product was roast (25.9%) and the most common information medium was suggestions by friends and parents (37.1%). The main as well as desired places of purchasing were both the supermarket (33.6% and 27.3%, respectively). The most preferred promotion method was free sample events (38.5%). From analyzing means-end chains of convenience meat products, the most dominant value chain was 'taste (A)'-'good taste (C)'-'feel good (V)'. These results show that consumption of convenience meat products will increase when consumer expectations of taste and satisfaction are met. Further, results of the value measurement provide information on consumer satisfaction and needs and can be applied to set marketing strategies for Korean style convenience meat products.
