  • The number of architects who adopt BIM(Building Information Modeling) as the design method are gradually increasing because of its productivity and efficiency. Climate Change and Global Warming lead to legislation of new energy regulations and strengthen existing ones. The current architectural design methods (2D CAD) take a lot of time and effort to verify energy codes and are hard to adjust according to the design changes. The purpose of this study is to show the effectiveness of the BIM in building envelop energy modeling of the housing project. In the process of design method change, We could contribute to increasing productivity and efficiency in building energy verification through BIM because the updated value could be calculated simultaneously without information omission or recalculation process. The procedure for the study is as follows. Using BIM of the Goldin at Essex Crosing Housing Project by Revit 2011 as a case model, this study analyze the criteria for energy plan to conform to the energy code in NYC. The result value from the setting of the Revit model is compared with the reference value required by the NYC Energy Code. Finally, the data from BIM are entered into COMckeck, the energy verification program provided by U.S. Department of Energy, to check whether the building envelope energy performance conforms to NYC Energy Code.

  • The purpose of this study is to investigate the conditions for improving space use and satisfaction by examing the behavior, focusing on the senior center, one of the leisure welfare facilities for the older adults. An online survey was conducted on 300 older adults aged 65 years old (104 males, 196 females) who had experience using senior centers. The results are as follows. First, the frequency of use per older adults was 1-3 times a month the most, and the preferred frequency of use was 1-3 times a week. The results showed that they wanted to use the Senior center frequently, but they could not use it often. Considering the high preference for health promotion activity programs in senior centers, it is understood that the use of space programs for health promotion can be increased if provided. Second, as the usage time per route ranges from a minimum of 1 hour to a maximum of 5 hours, it is considered that satisfaction and usability can be improved if a space to support various personal activities is provided. Third, it is considered to be helpful to improve the program or space composition that can strengthen friendship or improve accessibility by appearing as difficulties in friendship and accessibility for the reasons not used per senior citizen.

  • Although safety and health education is reported to be very effective in reducing the industrial accident rate, the demand for improvement in safety and health education is also very high. The purpose of this study is to present measures to enhance effectiveness by investigating the effectiveness and demand for safety and health education for supervisors among the safety and health education systems. As a result of the study, it was found that the satisfaction and effectiveness of safety and health education were low. As the most important competency required for supervisors, it was investigated that job competency was the ability to discover harmful risk factors and formulate disaster prevention measures in the work process and work environment, and base competency was communication ability. In addition to designated safety and health education institutions, there was a high demand for recognition as education completion time even when professional education by job was completed by other professional education institutions. Therefore, in safety and health education for supervisors, it is necessary to focus on major items to improve supervisors' job competency and base competency, and to recognize that they have completed education at a wide range of educational institutions. We believe that it can increase the supervisor's capacity for safety management and improve the effectiveness of safety and health education.

Non-conductive Film Effect on Ni-Sn Intermetallic Compounds Growth Kinetics of Cu/Ni/Sn-2.5Ag Microbump during Annealing and Current Stressing (열처리 및 전류인가 조건에서 Cu/Ni/Sn-2.5Ag 미세범프의 Ni-Sn 금속간화합물 성장 거동에 미치는 비전도성 필름의 영향 분석)

  • The in-situ electromigration(EM) and annealing test were performed at 110, 130, and 150℃ with a current density of 1.3×105 A/cm2 conditions to investigate the effect of non-conductive film (NCF) on growth kinetics of intermetallic compound (IMC) in Cu/Ni/Sn-2.5Ag microbump. As a result, the activation energy of the Ni3Sn4 IMC growth in the annealing and EM conditions according to the NCF application was about 0.52 eV, and there was no significant difference. This is because the growth rate of Ni-Sn IMC is much slower than that of Cu-Sn IMC, and the growth behavior of Ni-Sn IMC increases linearly with the square root of time, so it has the same reaction mechanism dominated by diffusion. In addition, there is no difference in the activation energy of the Ni3Sn4 IMC growth because the EM resistance effect of the back stress according to the NCF application is not large.

  • In order to avoid the spread of Covid-19, outdoor activities are decreasing worldwide and the time spent at home is increasing. As physical activity declines, the number of people who feel bored, restless and immune deficient is increasing. As indoor life becomes more permanent, multiple approaches to home workout are becoming active. This paper examines how the Covid blue (boredom and social anxiety) produced in the no-touch era affects quality of life through the use of home training applications. Questionnaires were collected from Chinese people using a website dedicated to Chinese questionnaires, and finally 383 appropriate data were analyzed using SPSS24.0 and AMOS24.0. The research results showed that the actual experience of using home workout had a positive impact on quality of life. The higher the user's sense of social unease about being late in the untact, It was found that the higher the social anxiety perceived by users about the untact era, the higher the interactivity and exercise satisfaction with the home workout app. Home workout application can improve exercise satisfaction and quality of life, which are more positive effects beyond the result of resolving consumers' boredom. Therefore, it can be used as a channel for digital services.

  • With the recent advent of the New Normal era, realistic technologies and non-contact technologies are receiving social attention. However, the hair styling field focuses on the direction of the hair itself, individual movements, and modeling, focusing on hair simulation. In order to create an improved practice environment and demand of the times, this study proposed a non-contact hair styling VR system. In the theoretical review, we studied the existing cases of hair cut research. Existing haircut-related research tend to be mainly focused on force-based feedback. Research on the interactive haircut work in the virtual environment as addressed in this paper has not been done yet. VR controllers capable of finger tracking the movements necessary for beauty enable selection, cutting, and rotation of beauty tools, and built a non-contact collaboration environment. As a result, we conducted two experiments for interactive hair cutting in VR. First, it is a haircut operation for synchronization using finger tracking and holding hook animation. We made position correction for accurate motion. Second, it is a real-time interactive cutting operation in a multi-user virtual collaboration environment. This made it possible for instructors and learners to communicate with each other through VR HMD built-in microphones and Photon Voice in non-contact situations.

  • Fairy tales are rooted in folk tales and contain human unconsciousness and universal emotions. It also plays a role as original content in various narrative transformation works. Andersen's brings numerous signification through symbolic signs of red shoes, dance, and ankle amputation. Victor W.Turner's theory of social drama broadens the perspective of narrative analysis. In addition, this theory makes us realize the conditions of the social community required by society at the time. As a circular content, Andersen's shows the double entry narrative of growth as a woman and incorporation into the social community. In this process, the social conditions accepted and rejected are symbolically revealed. In Koo Byung-mo's novel , achromatic color and red color are contrasted. The red world is full of vitality and represents the meaning of human existence. Yoon Mi-kyung's fairy tale is divided into different characters from the girl's growth narrative and the outsider's entry into the women's society. This work accuses preconceived notions and prejudices against multicultural families and strangers.

  • The purpose of this study is to derive major topics in content R&D and provide directions for academic development by exploring research trends over the past 20 years using topic modeling targeting 9,858 papers published in the Journal of the Korean Contents Association. To secure the reliability and validity of the extracted topics, not only the quantitative evaluation technique but also the qualitative technique were applied step-by-step and repeated until a corpus of the level agreed upon by the researchers was generated, and detailed analysis procedures were presented accordingly. As a result of the analysis, 8 core topics were extracted. This shows that the Korean Contents Association is publishing convergence and complex research papers in various fields without limiting to a specific academic field. Also, before 2012, the proportion of topics in the field of engineering and technology appeared relatively high, while after 2012, the proportion of topics in the field of social sciences appeared relatively high. Specifically, the topic of 'social welfare' showed a fourfold increase in the second half compared to the first half. Through topic-specific trend analysis, we focused on the turning point in time at which the inflection point of the trend line appeared, explored the external variables that affected the research trend of the topic, and identified the relationship between the topic and the external variable. It is hoped that the results of this study can provide implications for active discussions in domestic content-related R&D and industrial fields.
