Molecular flux distribution from the thermal evaporation source using Monte Carlo method: The importance of interparticle collision

현경호,김성문,임종인,나영혁,정광호,이현복,이연진 한국물리학회 2019 Current Applied Physics Vol.19 No.11

Molecular flux distribution is critical information to obtain uniform thin films using the thermal evaporation technique in vacuum. However, the flux distribution is a quite complex function depending on the geometry of evaporation sources and the individual motion of evaporated molecules. This makes it difficult to establish a model describing the flux distribution that is directly associated with the distribution of film thickness on the substrate. In this study, we found that the conventional analytic model severely deviates from the experimental flux distribution except in the simple case. Thus, we developed a numerical model based on the Monte Carlo method to simulate the angular flux distribution from a thermal evaporation source. In particular, interparticle collisions have been handled rigorously. Evaporated molecules were assumed to be point particles that collide with each other and adsorbed (emitted) on (from) the nozzle wall of the source. The interparticle collision probability was addressed with the rarefied gas dynamics and the cosine law of emission was adopted to simulate the adsorption/emission process at the nozzle wall. Finally, we compared the simulated flux distribution with experiments on the cylindrical nozzle with various aspect ratios and deposition rates. The simulation results show excellent agreement with experimental data, indicating that interparticle collision is a key parameter for accurate simulation.

Objectives of this study is to examine the effects of service quality and relational benefits on employee satisfaction and restaurant satisfaction in large-scale independent restaurants. The data were collected from 200 customer of five restaurants and analyzed with SPSS 12.0. In order to identify factor structure of service quality and relational benefits, the principle component factor analysis with varimax rotation was performed. The dimensions of service quality were responsiveness/reliability, food quality, empathy, tangibility and assurance, while the dimensions of relational benefits were customerization, economic benefit, social benefit and psychological benefit. The results of multiple regression analysis indicated that relational benefits had significant effect on employee satisfaction, and service quality had significant influence on restaurant satisfaction. The theoretical implications of these findings were discussed.

Chesin-1 telephone currently used in Korea is quite similar in design to early Japanese model of Type-4 telephone which is now being replaced by Type-600 having much improved characteristics. Chesin-1 telephone has a relatively high side-tone level, since the line impedance was taken as a purely resistive component for simplicity in the design of its transmission networks. To meet a current trend of using a smaller diameter of wire for telephone line, it is necessary to improve the present type which has a limited receiving efficiency. A new telephone set has been designed to have an amplifier and a R-C coupled side-tone balancing network. The set offers 8dB gain in the overall performance of transmitting and receiving without any unbearable side-tone disturbances. The paper describes both theoretical and experimental characteristics of the new set.

버내큘러 디자인 특성을 반영한 전통시장 간판의 표현 전략

시대적 흐름의 양상으로 `우리 것을 통하여 세계로 나아가자`의 의미를 가진 글로벌리즘(globalism)과 로컬리즘(localism)이 결합한 용어인 글로컬리즘(glocalism)이라는 새로운 개념을 탄생시켰다. 세계화와 지역화라는 양립적인 이분법을 극복하는 글로컬리즘은 세계화와 상응을 이루면서, 지역화로서의 고유한 문화 정체성을 보존하는 것을 의미한다. 연구자는 세계적 흐름에 발맞추어 지역적, 시대적, 문화적 가치가 축적된 대표 상업공간인 전통시장과 버내큘러 디자인을 글로컬리즘에 부합하는 산물로 여기고 새로운 가치를 창출하고자 하였다. 전통시장의 버내큘러 디자인 간판 사례를 파악하여 경쟁력을 분석하고, 버내큘러 디자인 특성을 반영한 전통시장 간판의 표현 전략을 수립하였다. 전통시장 간판의 차별화 방법을 지역 방언의 활용, 구어적 의사소통, 캘리그라피, 소재의 다양화로 바라보았다. 이러한 표현 방법은 정부의 간판개선사업으로 천편일률적으로 동질화 · 획일화되어가고 있는 전통시장의 문화 정체성을 확립하는 데 도움이 될 수 있을 것으로 생각된다. 본 연구를 통해 전통시장의 정체성을 확립하고 특색 있는 거리 분위기를 조성해 전통시장이 지역 주민들의 커뮤니티 공간으로 거듭나기를 기대해본다. New concept, Glocalism which combined Globalism symbolizing `Let`s go out into the world with ours.` with Localism was born. As Glocalism which overcame compatible dichotomy responds to Globalism, it means to preserve unique and original culture identity, as Localism. Following global trend, researchers regarded traditional markets which are representative commercial spaces with accumulated regional, periodical, and cultural values and vernacular designs as products which correspond to Glocalism and tried to create new values. Therefore, identifying the signboard cases with vernacular designs in traditional markets, competitiveness was analyzed. The expression strategies of traditional market`s signboard reflecting the features of vernacular designs were established. The differentiation methods of traditional market signboards were reviewed by local dialect application, colloquial communication, calligraphy, and diversification of materials. These expressions are considered helpful to establish cultural identity of traditional market which is becoming assimilated and standardized groovily. Through this study, it is expected that the identify of traditional market is established and reborn as a community space for the local citizense by creating and building unique and original street atmosphere.

연구배경 본 연구는 재난 정보를 위험사회에서 안전한 생활을 영위하게 하는 데 필수불가결한 수단으로 인식함에 따라 재난 정보의 효과적인 정보 시각화를 위해 재난 정보디자인의 매체별 시각요소를 분석하는 데 목적이 있다. 연구방법 대국민 재난 정보 서비스를 토대로 인쇄 매체의 매뉴얼, 컴퓨터 매체의 웹 사이트, 모바일 매체의 어플리케이션을 연구대상으로 선정하고, 정보 시각화의 필수요건인 자크 베르텡의 그래픽 요소와 타이포그래피의 표현요소가 갖는 주요 시각요소를 색채, 형태, 크기, 위치와 방향으로 도출하였다. 그리고 조형원리에 근거한 정보디자인의 시각적 효과를 분석기준으로 국내·외 재난 정보디자인의 매체별 시각요소를 비교분석하여 국내 재난 정보디자인의 문제점과 개선방향을 제시하였다. 연구결과 국내 재난 정보디자인은 정보의 양은 많으나 정보의 위계나 구분을 나타내는 시각요소 간의 차이가 작고, 여백은 부족하고 불규칙하였다. 그리고 색채의 사용량은 많았으며 텍스트의 가독성은 뛰어나지만, 자간과 행간, 글자의 크기와 무게에 대한 고려가 부족한 것으로 나타났다. 따라서 국내 재난 정보는 정보전달자 중심으로 제작되어 사용자가 정보습득에 대한 실효성이 낮고, 매체별 통일성이 없는 정보디자인으로 사용성에 혼란을 주는 것을 알 수 있었다. 결론 효과적인 재난 정보디자인을 위해서는 신뢰성 있는 정보설계와 시각요소 간의 연계성을 고려하여 조화롭게 구성해야 하며, 정보의 위계 및 구분을 명확히 하여 시각적 효과를 극대화해야 한다. 또한, 구상적 이미지와 최소한의 텍스트를 사용하여 공간의 효율성과 정보전달력을 높여야 하며, 재난 정보디자인의 통합 가이드라인을 구축하여 효과적인 재난 정보전달체계를 형성해야 한다. Background The purpose of this study is to analyze visual factors of disaster information design demonstrated by mass media since disaster information is considered to be essential to live a safe life in current society. Methods manuals, websites of computer media, mobile applications are selected as the research subjects. In addition, graphic factors proposed by Jacques Bertin, the essential factors of information visualization and visual factors of typographic were analyzed by classifying into colors, forms, size, location and design based on the analysis standards of information design by moudling principles. In this way, visual factors of disaster information design in domestic·overseas media were compared and analyzed to propose the problems and improvement directions of disaster information design in Korea. Result disaster information design in Korea has excessive amount of information less difference in visual factors indicating hierarchy and classification of the information and irregular and insufficient margin. Furthermore, the usage of colors was excessive and the consideration of the font size and weight was insufficient while text readability was superior. As such, it has been found that disaster information in Korea was created focusing on the information communicator thus the users cannot receive the information properly and the information causes confusion to the users due to information design lacking unity. Conclusion In order to resolve the issues and create effective disaster information design, the design should consider linkage between information design and visual factors while clarifying information hierarchy and classification to maximize visual effects. Also, concrete image and minimum texts should be used to improve space efficiency and information delivery. In this sense, integrative guidelines regarding disaster information should be established to form a disaster information delivery system.
