Through the development of efficient data collecting technologies like RFID, and inter-enterprise collaboration platforms such as web services, companies which participate in supply chains can acquire visibility over the whole supply chain, and can make decisions to optimize the overall supply chain networks and processes, based on the extracted knowledge from historical data collected by the visibility system. Although not currently active, the MeatWatch system has been developed, and is used in part for this purpose, in the imported beef distribution network in Korea. However, the imported beef distribution network is too complicated to analyze its various aspects using ordinary process analysis approaches. In this paper, we suggest a novel approach, called RFID-based supply chain process mining, to automatically discover and analyze the overall supply chain processes from the distributed RFID event data, without any prior knowledge. The proposed approach was implemented and validated, by using a case study of the imported beef distribution network in Korea. Specifically we demonstrated that the proposed approach can be successfully applied to discover supply chain networks from the distributed event data, to simplify the supply chain networks, and to analyze anomaly of the distribution networks. Such novel process mining functionalities can reinforce the capability of traceability services like MeatWatch in the future.

This study aims to investigate the usage patterns of users in Social Network Services (SNS) where is an upsurge. Specifically, the paper considers the reason why young people more and more prefer online (or mobile) SNS activities rather than offline face-to-face social relationship. Furthermore, the drivers which affect SNS usages are considered from users' personal characteristics and social influences. User's personal characteristics include their personalities (extraversion and introversion), narcissism, and life satisfaction. Social influences involve subjective norm, visibility, and image. Affected by personal and social factors in SNS, users intend to show positive self-presentation, which refers to a behavior to selectively expose his/her goodness to others. As one of the most influential drivers affecting SNS usage, the positive self-representation has an effect on the level of SNS usage. Thus, this paper suggests the hypothesized research model focusing on positive self-representation in the relationship among personal characteristics, social influence, and user's behavior in SNS. Empirical data analysis with 100 questionnaires suggests that all hypotheses were adopted except for the effect of visibility among social influence factors on positive self-representation.

연극공연 산업은 대표적인 문화 콘텐츠 산업임에도 불구하고 그동안 국가 차원의 지원이 빈약하고 연극 관련 종사자들도 연극환경과의 능동적인 상호작용보다는 연기력 향상 등 개인 노력에 치우쳐온 경향이 있다. 그래서 연극 산업에 대한 실효성 있는 활성화 대책의 필요성이 커지고 있으며, 이는 연극과 연극환경과의 상호작용의 질을 증진하는 데서 찾아야 할 것이다. 이에 본 연구의 목적은 연극 배우들의 연극의 주요 환경인 정치, 기업 및 테크놀로지와의 상호작용 정도가 연극의 활성화에 미치는 영향을 분석하는 것이다. 이를 위해 소셜네트워크 분석을 수행하였다. 연구 결과 매개 중심성이 소셜네트워크 상의 연극 관련 액터(연극인, 연극기관)들의 가시성에 유의한 영향을 주는 것으로 나타났다. 이는 연극 관련 액터가 연극환경 요소들 간의 정보나 자원흐름의 중심에 있을수록 더욱 가시성이 높아진다는 의미이며, 연극이 적극적으로 테크놀로지를 습득하며 아방가르드를 창출하고, 정치 및 기업과의 능동적인 상호작용을 통해 영향력과 외연을 넓히는 노력을 부단히 해야함을 보이고 있다.

The purpose of this study is to investigate the effect of makeup, clothing tone and clothing style on wearer's with same color coordination of lipstick and clothing. The experimental materials developed for this study were a set of stimulus and response scales (7-point scale semantic). The stimuli were 64 color pictures were manipulated by computer simulation. This experiment design was $2{\times}2{\times}4{\times}4$ factorial design. The stimuli were a set of eyeshadow color(brown), clothing style (formal style of Jacket / skirt and casual style of cardigan / pants), lipstick and clothing color (red and orange), lipstick tone(vivid, light, dull and dark), clothing tone(vivid, light, dull and dark). The subjects of this research were 384 female undergraduates living in Gyeongsangnam-do. The investigation was carried out at a lecture hall at the time between 10 a.m. and 3 p.m. in May 2006. The data were analyzed using SPSS program. Factor analysis, 4-way ANOVA, t-test, and Duncan test were used as analysis methods. Image factors according to variation of clothing style, clothing color, and makeup color are composed of 4 different dimensions (visibility, attractiveness, tenderness, and stability). In dimension of the visibility, the image was perceived to be glowing and luxurious regardless of lipstick tone and lipstick color in the case of the vivid tone clothing. According to the variation of clothing style, clothing color and tone, makeup color composed of eyeshadow color, lipstick color and tone, it was investigated that the images for a clothing wearer were expressed diversely, were shown differently in image dimensions, and could be produced to different images. The analysis data for images according to the combination of makeup and clothing color, tone, and style thus provide basic material for image consulting or color coordination.

QZSS(Quasi-Zenith Satellite System)는 일본의 위성항법시스템으로 도심지역에서 GPS 시스템의 가시성 향상을 위해 계획되었다. 첫 번째 위성(Michibiki)이 2010년 발사되었으며 이후 정상적으로 항법신호를 방송하고 있다. 따라서 본 논문은 GPS와 QZSS를 이용한 통합위성항법시스템의 성능을 분석하는데 목적이 있다. 특히 한반도 주변에서의 통합위성항법 시스템 사용 관점에서 연구가 진행되었으며, QZSS 시스템의 특성 분석, 실험 장비를 이용한 실측 및 통계적 분석 등을 통해 체계적인 연구를 하여 GPS와 QZSS 위성항법 시스템이 가시성측면에서 장애를 받는 경우 뿐 아니라 평상의 위치 측정에도 더욱 신뢰성이 높음을 확인하였다. 또한 한반도 영역에서 다양한 항법파라미터 향상에 GPS와 QZSS 통합위성항법시스템이 매우 유용할 것으로 전망된다.

The Korean first geostationary meteorological satellite, COMS, will be launched during second half of 2009. For the next meteorological geostationary satellite mission, KARI is now preparing the development process and tools. As one of the endeavor, a software tool is being developed for the analysis and design of geostationary transfer orbit. Generally, these kind of tools should be able to do various analysis works like apogee burn planning, dispersion analysis, ground visibility analysis, and launch window analysis etc. In this presentation, a brief introduction about a design process and analysis software tool development. And simulated calculation results are provided for the geostationary transfer orbit. These software can be used for the next geostationary satellite mission design and development.

Korean marks case for subjects and objects, but it is well known that case-markers can be dropped in certain contexts. Kwon and Zribi-Hertz (2008) establishes the phenomenon of Korean case drop on a single factor of f(ocus)-structure visibility and claims that both subject and object case drop can fall under a single linguistic generalization of information structure. However, the supporting data is not empirically substantiated and the tenability of the f-structure analysis is still under question. In this paper, an experiment was conducted to show that the specific claims of Kwon and Zribi-Hertz's analysis that places exclusive importance on information structure cannot be adequately supported by empirical evidence. In addition, the present study examines H. Lee's (2006a, 2006c) multi-factor analysis of object case drop and investigates whether this approach can subsume both subject and object case drop under a unified analysis. The present findings indicate that the multi-factor analysis that involves the interaction of independent factors (Focus, Animacy, and Definiteness) is also compatible with subject case drop, and that judgments on case drop are not categorical but form gradient statistical preferences.

대기환경문제가 전지구촌의 현안과제로서 그 무엇보다 중요성이 크게 부각되고 있다. 이와 더불어 날로 높아져 가는 국민들의 쾌적한 환경에 대한 기대와 요구는 우리나라가 시급하게 해결해야하는 대기환경분야의 실질적 개선 방향으로 대도시 시정장애 현상을 제시하였다. 현재 정부의 청정연료와 저황유공급 확대, 저공해자동차 보급 등 각종 대기오염 저감정책에 힘입어 아황산가스와 먼지 등 개도국형 대기오염상태는 개선되는 추세이나, 자동차의 증가로 인한 이산화질소 및 오존의 오염도는 완만하게 증가하고 있는 상황이다. (중략)

주 구성요소가 산소와 질소 기체인 대기는 백색광을 지닌 광원, 즉 태양광에 대하여 선택적으로 빛을 산란시킴으로써 파란색을 나타낸다. 이것은 Rayleigh scattering 효과가 파장의 4승에 반비례하기 때문에 450nm 부근의 파란색은 700nm 부근의 빨간색에 비하여 약 6배이상 강한 빛을 산란시키기 때문이다. 그러나 실제로 하늘은 고정된 색을 지니고 있지는 않다. 태양과 관측자 및 관측지점의 유기적 관계에 의하여 하늘의 색은 주기적이며 임의적으로 다르게 보인다. (중략)

Optimal allocation of viewers on a terrain in such a wav that the hidden area would be minimized has many practical applications. However, it is impossible in practical sense to evaluate all the possible allocations. In this paper, we propose an optimal allocation of viewers based on genetic algorithm that enables probabilistic search of huge solution space. An experiment for one and three viewers was performed. The algorithm converges to good solutions. Especially, in one viewer case, the algorithm found the best solution.
