변환 도해를 바탕으로 한 실시간 소프트 웨어 개발을 위한 자동화 도구
박성주(Sung Joo Park),김형도(Hyoung Do Kim) 한국정보과학회 1987 한국정보과학회 학술발표논문집 Vol.14 No.1
시스템의 자동화 추세에 따라 실시간 소프트웨어의 중요성은 점차 증대되어 왔다. 그러나 이의 중요성에 반하여 실시간 소프트웨어 개발 도구는 극히 제한되어 있으며 많은 제약을 내포하고 있다. 자료흐름도의 확장형태인 변환도해를 바탕으로 하는 방법론은 이러한 문제점에 대한 중요한 접근법을 제시하고 있다. 본 논문에서는 이러한 변환도해의 개발 방법론을 위한 자동화 도구를 디자인하였다. 이 도구는 서울 시경의 명령, 통제, 통신 그리고 지능(C³I) 시스템에 적용되었으며 변환도해의 요구 명세서에서 많은 불일치 점들을 제거하고 동적인 테스트 법칙들을 오류없이 적용하므로서 완전성을 증가시킬 수 있었다.

This ethnographic study investigated aspects of negative social power in 4-year-old children and characteristics of the children who use it. The negative use of social power included taking the possessions of peers without permission, ignoring classroom rules, controlling, rejecting, and threatening others. Most children who abused social power behaved as controllers and were popular children or had a following within the group. They were physically superior to peers, of competitive disposition, and had a well-developed capacity for verbal expression; they were self-centered and had a high level of cognitive ability. Further areas for ethnographic research into the nature of the negative use of social power in young children include training in perspective taking, age differences, and factors that contribute to the development of negative social power in young children.

체육학의 오랜 질문인 ``체육교육이 도덕교육에 공헌할 수 있는가``는 여전히 활발한 논쟁 속에 있다. 지금까지도 많은 학자들에 의해 경험적 검증과 개념적 논의가 지속적으로 진행되고 있지만 긍정적으로 보는 입장과 부정적으로 보는 입장으로 대립되어 어느 한쪽도 명확한 결론에 이르지 못하고 있는 이슈 중에 하나이다. 이 논문의 목적은 체육수업과 도덕교육의 논리적 관련성을 규명함으로써 체육수업이 도덕교육에 공헌할 수 있음을 논증하는데 있다. 선행된 대부분의 연구들은 체육의 내재적 혹은 외재적 가치를 중심으로 도덕교육과의 관련성을 연구한 반면 이 논문은 도덕교육에 대한 해석을 중심으로 체육교육이 얼마나 이 교육에 필연성을 가지고 있는지를 논리적으로 규명하는 데 초점을 두었다. The perennial question about whether physical education can contribute to moral education has been the subject of continuous debate. As yet, however, there seems to be little conclusive evidence one way or another. Thus, this study attempts to find the necessary evidence that there is a logical connection between engagement in sport or physical education and moral education. Most of the existing work regarding sport`s relation to moral education is based largely on the examination of internal or external values of sport to argue that physical education is inherently concerned with moral values and can contribute to the development of moral character. However, this study attempts to approach the issue in a little different way. With a focus on analysis of moral education, this study attempts to show how closely and logically participation in physical education class is related to moral education.
저온 생장성이 우수한 분리 미세조류 Tetraselmis sp. 5개주의 생장 패턴 및 지방산 조성 분석

For successful microalgal biodiesel production, the strain should be selected carefully. Fast growth rate and high fatty acid contents are desired traits for algal biodiesel production. In ocean cultivation of microalgae, seawater temperature slowly changes over seasons, and rotating algal strains in accordance with their optimal temperature could improve overall productivity. Additionally, use of indigenous strain is preferred to alleviate potential impacts on the environment. In this study, five strains of Tetraselmis sp. from nearshore of Youngheung Island, Incheon, Korea, were isolated during winter and characterized for their growth patterns and fatty acid compositions in the low temperatures (5–15°C). The five strains showed various characteristics in optimal growth temperature, fatty acid contents, and compositions. Compared with a strain of Tetraselmis sp., isolated from Ganghwa island in a previous study, a rapid-growing strain with 237% higher biomass productivity and an oleaginous strain with twice higher fatty acid contents at 10°C were isolated. The oleaginous Tetraselmis strain showed the highest fatty acid productivity among the strains, having 438% higher productivity than the previous strain. Using the new isolates in the seasons with low seawater temperature would improve microalgal fatty acid productivity in ocean cultivation.

Streaming Technology can support the real-time playback without downloading and storing multimedia data in local HDD. So, client browser or plug-in can represent multimedia data before the end of file transmission using streaming technology. Recently, the demand for efficient real-time playback and transmission of large amounts of multimedia data is growing rapidly. But most users' connections over network are not fast and stable enough to download large chunks of multimedia data. In this paper, we propose an intelligent IP streaming system based on personalized media service. The proposed IP streaming system enables users to get an intelligent recommendation of multimedia contents based on the user preference information stored on the streaming server or the home media server. The supposed intelligent IP streaming system consists of Server Metadata Agent, Pumping Server, Contents Storage Server, Client Metadata Agent and Streaming Player. And in order to implement the personalized media service, the user information, user preference information and client device information are managed under database concept. Moreover, users are assured of seamless access of streamed content event if they switch to another client device by implementing streaming system based on user identification and device information. We evaluate our approach with manufacturing home server system and simulation results.
