Intermedia refers to the convergence of media. The advance of intermedia has not only facilitated the delivery of brand messages in contemporary fashion shows but also facilitated interactive communication. This study investigated the mediating roles played by various media in fashion and fashion shows, focusing on the phenomenon of intermedia in contemporary fashion shows. To investigate the impact of intermedia on contemporary fashion shows, we conducted a social network analysis-a promising approach for research into fashion trends. Analyzing 159 fashion-related articles published in the 2000s, we extracted intermedia-related words (n=253). The relation-ships between keywords made an analysis of between centrality, and cluster variables applied Clauset-Newman-Moore by using KrKwic and NodeXL programs. The results of the between centrality analysis indicated that the most important factors in contemporary fashion shows are "models" and "stages." We found that the impacts of intermedia on contemporary fashion shows can be divided into four categories: "model performance," "symbolic stage management," "new media utilization," and "convergence in arts." Our analysis thus identified considerable synergy between the characteristics of intermedia and contemporary fashion shows. These results have found intermedia-related commonalities in intermedia and fashion show, and this might increase customer interest in fashion, a positive outcome for the fashion industry.

In the fashion industry, the thing that shows the latest trends and makes issues is the fashion show. The function of fashion shows is changing from a promotional mean to a method of communication with customers. Recently, some fashion shows have used digital images and omitted traditional parts of a fashion show such as models, stages, garments, music and audiences. In this study, 30 fashion shows that used digital images were selected from the 2000-2010 collections of Paris, Milan, London and New York, and its communication characteristics were analyzed and discussed. The three categories of the communication characteristics are as follows: First, the shows used digital images as stage sceneries or effects to create desired stage effects. The digital images were used as extra tools to reinforce the concept of the fashion show. Second, the fashion shows used real-time videos to extend its presentation into the virtual space. The interactive videos were designed to encourage audiences to actively participate in the show. Third, the digital images were the focus of the show for the internet-only digital fashion shows. Since the Internet is not constrained by time or space, multi-faceted, communication between audiences and fashion designers or among audiences is possible. In addition, the number of audience it can reach is higher than traditional fashion shows. Digital images will be used more often in the fashion shows. In the future, fashion shows will try to become more interactive with audiences through the use of new digital image technology.

Along with global environmental issues, the size of the electric vehicle market has recently skyrocketed. Various efforts have been made to extend mileage, one of the biggest problems of the electric vehicles, and development of batteries with high energy densities has led to exponential growth in mileage and performance. However, proper thermal management is essential because these high-performance batteries are affected by continuous heat generation and can cause fires due to thermal runaway phenomena. Therefore, thermal management of the battery is studied through the optimal design of the guide vanes, while utilizing the existing battery casing to ensure the safety of the electric vehicles. A battery from T-company, one of a manufacturer of the electric vehicles, was used for the research, and the commercial CFD software, ANSYS CFX V20.2, was used for analysis. The guide vanes were derived through optimal design based on a genetic algorithm with flow analysis. The optimized guide vanes show improved heat removal performance.

In the COVID-19 era, globally, companies in the fashion industry are pursuing new convergence methods through digital technology. Conventional fashion shows have become difficult to run exclusively, instead, the shows are run through a combination of offline and digital arrangements. This paper examines the trends of seven digital fashion show weeks in London, Paris, Milan, New York, Seoul, Shanghai, and Tokyo, and presents strategies applicable in Korea's Seoul Digital Fashion Week. We focused on the digital technology used in the digital fashion weeks fashion brands, and the characteristics of the host cities. The study conducted a literature review and case study through corporate and research report data, and the Fashion Week website. Based on the study results, changes in fashion industry calendars like 'See now, Buy now', seasonless, and unified collections for men and women, expansion of D2C system, the rise of short-form contents, and the expansion to the virtual world space and physical limitations can be cited as changed trends. The study provides insight into the incorporation of the Korean Wave and K-Pop singers, industrial structure change, and the establishment of B2B system in the Seoul digital fashion week. The shift to the digital runway is not only an alternative method to cope with the COVID-19 era but also a new "new normal". Fashion shows are no longer fixed and planned in free spaces. As a venue displaying the creator's personality, digital fashion week is expected advance in the future.

Obstacle Limitation Surface (OLS) is conceptual surface establishing the airspace around aerodromes to be maintained from obstacles to ensure safe aircraft operations. Despite advances in the technologies for aircraft, navigation systems and the development of new flight procedures, the criteria defining OLS have not been amended since its initial establishment, resulting in the overestimation of areas for height restriction. As there were requests to examine OLS at the 12th Air Navigation Conference and the 38th ICAO Assembly, the research on the OLS revision began in earnest and ICAO has proposed Obstacle Free Surface (OFS) and Obstacle Evaluation Surface (OES) as an alternative of the existing OLS. OFS is surfaces where obstacles shall not be permitted, and OES is ones where obstacles be evaluated with an aeronautical study and could be permitted under some conditions. The purpose of this study is to preemptively assess the efficiency and safety of OFS and OES by applying them to the second runway (15L/33R) of Incheon International Airport. The results show that OFS and OES are capable of serving the instrument flight procedure safely with a smaller obstacle clearance area compared to the existing OLS.

본 논문에서는 FOD (foreign object debris) FMCW (frequency modulated continuous waveform) 레이다에 대한 지상 클러터 모델링 및 검출 성능에 미치는 영향을 분석한다. 레이다 수신신호에는 FOD에 의해 반사된 신호 뿐 만 아니라 활주로 표면 및 잔디영역에 의해 반사된 신호까지 포함된다. FOD의 RCS (radar cross section)가 잔디영역의 RCS와 거의 같기 때문에 클러터 제거 알고리즘을 적용하지 않으면 FOD의 검출이 어렵다. 또한, FOD와 클러터 모두가 움직이지 않기 때문에, 대표적 클러터 제거 알고리즘인 MTI (moving target indicator) 기법의 적용이 어렵다. 따라서 클러터 맵을 이용한 클러터 제거 기법이 필요하고, 이를 위해서는 활주로 표면을 고려한 클러터 맵을 정확하게 생성하는 것이 중요하다. 본 논문에서는 신뢰도 높은 클러터 맵을 생성하기 위해 FOD가 없는 표면의 경우에만 모든 범위의 레인지 빈에 대해 각각의 비트신호를 생성하고, 생성된 비트 신호를 100번 누적하였으며 RCS 값에 웨이블 분포를 적용하였다. 시뮬레이션 결과는 생성된 클러터 맵을 FOD FMCW 레이다에 적용함으로써 FOD가 제대로 검출됨을 보인다.
