Viologen decorated polyhedral oligomeric silsesquioxane for electrochromic devices on plastic substrate

최준홍,( Pande Gaurav Kiranrao ),박종승 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-

Electrochromic devices (ECDs) exhibits color change reversibly on applying an external potential. Viologen derivatives were frequently employed as an electrochromic material in ECDs owing to their simple molecular structure and simple synthetic modification. However, viologens have often suffered from significant drawbacks, such as inferior coloration efficiency, low switching speed, and reduced long-term stability. As for electrodes, there have been various attempts for transparent conducting electrodes (TCEs) were investigated. As a measure to effectively address these issues, here we present the use of octa-hexyl viologen substituted polyhedral oligomeric silsesquioxane as an electrochromic material. The TCE compositions were prepared by the mixture of silver nanowire and PEDOT:PSS and then spray-coated on the plastic substrate. The electrochromic performances of the plastic ECDs were investigated in terms of cyclic voltammetry, spectroelectro-chemistry, and kinetic stability.

진(Jeans) 브랜드 <디젤(Diesel)>의 광고와 패션쇼 그리고 퓨전문화

최준홍(Choi, Junhong) 글로벌문화콘텐츠학회 2010 글로벌문화콘텐츠 Vol.0 No.4

본 연구는 현대사회에서 패션브랜드가 가져야 하는 정체성과 퓨전문화시대의 패션유행의 방향성 재고에 대한 논의를 위해 청바지를 그 대상으로 선정했다. 또한 많은 청바지 브랜드 중 문화를 커뮤니케이션의 주된 수단으로 활용하며 반(反)패션적인 마케팅을 실시하고 있는 진(jeans)브랜드 디젤(diesel)을 분석의 대상으로 삼았다. 논문이 설정한 주제의 연구를 위해 디젤의 광고커뮤니케이션과 패션쇼를 중점적으로 분석하였다. 먼저 광고커뮤니케이션은 1990년대부터 2000년대까지의 사례 중 문화를 활용한 형태를 역사적사건의 패러디, 사회 환경 캠페인, 정치적 캠페인 문화혼종화 등의 유형으로 분류하여 분석을 실시했다. 각각의 광고는 청바지 자체의 유혹적인 이미지를 부각하기 보다는 우리가 만들어낸 역사, 사회적 현상, 환경, 정치적 상황을 그들만의 독특한 기법을 통해 우리가 한번쯤은 생각해봐야 할 시사적인 메시지로 가공하여 전달하고 있다. 또한 서로 다른 문화를 혼합하는 방식을 사용하여 제3의 문화 혼종적인 이미지를 만들어내어 문화 다양성에 근거한 시선으로 세계와 소통하고 있으며, 직접적인 상품의 홍보보다는 광고가 만들어 낸 메시지를 통해 상품 가치를 부여하고 있다. 이러한 성향의 주제가 공연의 성격을 가지는 패션쇼에서 어떻게 표현되는가를 알아보기 위해 디젤 패션쇼의 제작에 사용된 주제를 분석하였다. 문화적 요소를 활용하여 만들어진 해당 시즌의 광고주제는 현장성과 동시성을 가지는 패션쇼를 위해 광고의 주제는 시간과 공간을 설정할 수 있는 주제로 변형되었으며, 세부적인 문화요소를 첨가한 이야기의 전개로 심화되었다. 본 연구는 문화를 활용한 실질적인 광고 및 패션쇼의 사례를 통해 패션브랜드의 커뮤니케이션 기법을 분석했으며, 유행의 전파에 있어서 강압적이고 획일적인 방법보다는 문화다양성에 근거한 커뮤니케이션의 방법을 지닐 수 있다는 패션의 긍정적인 면을 발견 했다. 더불어 패션의 분야에서 문화콘텐츠로 활용된 문화를 살펴볼 수 있었다. 결론적으로 본 논문을 통해 이야기하고자 하는 것은 유행의 전파에 있어서 문화다양성에 근거한 커뮤니케이션이 중요하며, 지구상의 모든 문화는 경계와 우열이 없으며 이것을 이해하고 포용하는 퓨전문화적인 사고에 의해 스스로의 이미지를 만드는 것이 21세기의 패션브랜드가 가져야하는 정체성과 패션유행의 방향성이 된다는 것이다. This research chooses jeans as a medium to discuss the significance of fashion brands identities and the direction of fashion trends in cross-cultural societies. Hence, this research focuses on jean brand Diesel to analyze the identity and trend of the fashion brand among many other jean brands. Unlike other jean brands, Diesel makes the best use of culture as its main communication means which transcends a fashion marketing norm of other jean brands. For more comprehensive analysis on the proposed topic, the author stresses on advertisement campaigns and fashion show cases of Diesel. First, advertisement campaigns that utilizes cultural exemplifications from 1990 s to 2000 s are analyzes and categorized into four different types : parodies of historical events, campaigns of socio-environment, and politic and mixtures of culture. Other brands’ advertisement campaigns that flaunt enticing images of their jeans, in contract Diesel chooses historical, social, environmental, and political situations and use its unique techniques to fabricate them into critical messages that people are bound to consider at least once in their life time. Moreover, Diesel mixes different cultures to create new cross-cultural images which promote Diesel’s idea of cultural diversity to the mass. Rather than directly marketing its products, Diesel conversely utilizes the messages of the advertisement campaigns to add the value to its products. Secondly, to investigate how its propensity is expressed in a fashion show as a form of performance, the themes of Diesel s fashion shows are analyzes with the following these elements of fashion, Utilizing cultural elements, the relevant season’s advertisement theme is transformed into a theme that is able to set up time and space in order to create a fashion show with locality and simultaneity. The theme deepens to unfolding of a story that contains detailed cultural elements. Furthermore, such theme becomes the element that provides dramatic effects to the fashion show, and creates various dramas at the scene. Consequently, it maximizes the advertisement campaign’s messages, and conveys them to the audience. The major significances of this research are analyzing communication methods of the fashion brand through cases of actual advertisement campaigns and fashion shows that utilize various cultures, and realizing the positive aspects of fashion through communication methods based upon cultural diversity rather than forceful and uniform methods of propagating trends. This research is also noteworthy in an aspect that it shows different cultures that are selected for the subject of cultural contents in the fashion industry. In conclusion, the author suggests that communication based on cultural diversity is critical to propagate trends. The research also stresses that there are no boundaries and superiority among different cultures, and creating images through understanding such creed and embracing cross-cultural mind set should be the base of identity and direction of fashion brands in 21st century.

The inhibitor effect on the shaped charge jet penetration

주재현,최준홍 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.11

A submunition is one of the small shaped charges and has a severe penetration capability when it is dispensed in large numbers from the sky. Neutralizing it is one of the major interests in military science. An inhibitor which can be formed inside of shaped charge liner when a submunition impacts soft material target plays an important role to the penetration performance. A silicone rubber material that shows suitable inhibitor character of being dug deep by submunition impact in penetration mechanism was selected. The penetration performance of a shaped charge adopted inhibitors was investigated through ballistic experiments and numerical simulations. A remarkable reduction of jet penetration capability was obtained from the experiment. Numerical simulation using LS-DYNA, which is a non-linear finite element analysis code, was also carried out to reconstruct the experimental results. The simulation results showed good agreement with the experimental results, providing insights into the noticeable reduction of jet penetration performance due to a silicone rubber inhibitor.

섬광 X선과 잔류관통깊이 분석을 통한 성형작약탄 제트에 대한 펄스전류 효과

주재현,최준홍,김동규,김시우,김정태,Joo, Jaehyun,Choi, Joonhong,Kim, Dongkyu,Kim, Siwoo,Kim, Jeongtae 한국군사과학기술학회 2015 한국군사과학기술학회지 Vol.18 No.5

In this paper, the effect of high voltage current pulse against shaped charge jet was analyzed through the visualization of jet behavior using flash X-ray and comparison of depth of penetration(DOP) into RHA(Rolled Homogeneous Armor) witness plates. The behavior of jet particles has been acquired using a flash X-ray equipment when current pulse was applied into the metal jet of a shaped charge(SC) warhead. Typical results such as jet breakup and radial jet dispersion, which are due to electromagnetic pressure by current pulse, have been obtained. Dozens of penetration experiments using a shaped charge with 55 mm diameter were performed according to various combinations of major parametric variables such as electrode spacing, standoff distance from SC warhead to electrode, and charge voltage. Subsequently, interrelations between major parametric variables and DOPs into RHA were analyzed.

텅스텐 중합금의 고속변형 연구

장순남,최준홍 대한금속재료학회(대한금속학회) 1999 대한금속·재료학회지 Vol.37 No.10

The dynamic behavior of a tungsten heavy alloy (WHA) have been studied using an exploding bridgewire (EBW) detonator to load stress pulse onto the alloy plate. The particle velocity at the rear free surface of WHA was measured with varying the specimen thickness by a velocity interferometer system for any reflector (VISAR). Simple experimental technique has been introduced herein to obtain the Hugoniot elastic limit and spall strength of metals. The peak pressure generated by the EBW detonator has been exponentially decayed with increasing the sample thickness. The fracture behavior of WHA caused by the tensile stress pulse is similar to that due to the Charpy impact test.
