데이터 편재 하에서 히스토그램 변환 기법에 기초한 효율적인 병렬 결합 알고리즘
박웅규,최황규 江原大學校 産業技術硏究所 1995 産業技術硏究 Vol.15 No.-
본 논문에서는 데이터 분포가 편재된 상황하에서 부하의 불균형과 버켓 오벌플로우 문제를 해결하기 위해 히스토그램 변환 기법을 이용한 데이터 분산 방법과 이를 기초로한 병렬 결합 알고리즘을 제안한다. 제안된 알고리즘의 성능은 시뮬레이션과 하이퍼큐브형 병렬 컴퓨터 상에서 실험적인 방법에 의하여 분석되었다. 그 결과 제안된 알고리즘이 기본의 해쉬 결합 방법보다 우수함을 보인다.

With advances in computer and communication technology, the on-line multimedia service system is becoming more and more common in various aspects of life, including education, training, entertainment, and publishing. To guarantee the quality of service in the system, it is necessary to play the continues media. such as video or audio, without stopping. However, since the traditional system do not consider the constraint, it is inadequate for a system to support the continuous media service. In this paper, we discuss technical issues for implementing a multimedia server to support efficiently the continuous media service. Firstly, we present an organization methodology of the continuous media server and discuss an application area of the server. Secondly, we present an overall software architecture for the server and discuss the implementation methodology of several software modules in the system. Finally, we present an efficient overall operating algorithm of the server to support the continuous media service.
韓國에서 忽布에 關한 硏究 : (Ⅰ) 收量性에 關하여 (Ⅰ) For the Productivity of Hop Cones
林雄圭,임동빈,黃鍾瑞 서울대학교 1973 서울대학교 論文集 Vol.23 No.-
This experiments was undertaken with the purpose of investigating that 3 hop varieties(Hallertau, Saaz, Shinshuwase) is adequate or not in Korean climatic conditions and economic conditions. And 100 random sampling of hop cones are measured fresh weight, dry weight, length and width and three hop growing areas of Kangwondo, North Kyongsangdo, and Su-won for productivity. The results obtained are as follows. (1) In fresh weight and dry weight, Hallertau, Shinshuwase are higher significantly than Saaz. (2) In length and width, Hallertau and Shinshuwase are higher than Saaz. It appeared that those are difference of hop varieties. (3) In the productivity, Hallertau and Shinshuwase are higher significantly than saaz. It appeared that saaz is inadequate in Korea In conclusion, Hallertau, Shinshuwase are adapted to the hop-growing areas of Kangwondo, North Kyongsangdo.

이 硏究는 靈芝의 성분을 알고져 시행하였다. 결과는 다음과 같다. 1. 일반성분은 약용버섯인 수설(Ganoderma applanatum)과 비슷하다. 특히 P, Ca은 수설보다 대단히 높다. 2. 5개 지역의 성분함량은 단백질은 곤지암이 15.6%로 가장높고, 지방은 곤지암이 4.5%로 높고, total suger는 파주가 25.9%로 높고, reduced suger는 곤지암이 1.26%, crude fiber는 곤지암이 58.7%, ash는 곤지암이 1.38%, Ca는 강화가 1652ppm, Mg는 강화가 595ppm, Fe는 여주가 56ppm, Mn은 강화가 45ppm, P은 강화가 2335ppm, Ge은 강화가 67.5ppb로 가장 높다. 이 영지는 앞으로 natural health food, functional food, 21 century food, medicinal drugs development가 기대된다. These studies were conducted on aproximate component of Ganoderma lucidum. The results were as follows: 1. General components are similar medicinal Ganoderma applanatum. But, P, Ca were very higher than Ganoderma applantum 2. The isolates of 5 locations show as follow: The concentration of protein and fat is highest in Konjiam isolate(15.6%, 4.5%) and total sugar is Pa-ju isolate(25.9%). Reduced sugar and crude fiber are most abundant in Konjiam isolate(1.26%, 58.75%). Konjiam isolate turns out the highest ash concentration (1.38%). The concentration of Ca and Mg are highest in Kang-wha isolate(1652ppm, 595ppm), Fe is in Yu-ju isolate (56ppm). High concentration of Mn(45ppm), P(2335ppm), and Ge(67.5ppb) enrich Kang-wha isolate. Ganoderma lucidum is expected to be natural health food functional food, 21 century food, and medicinal drugs.

The IS(information systems) organization is a stressful organization. However, there is little theoretical or empirical research on the effects of job stress on IS organization. A major reason is because IS organization and researchers are unaware of the consequences of job stress and unfamiliar with the job stress literature. The purpose of this paper is to propose a theoretical framework of job stress on IS organization. Based on a review of the IS, psychology, and general management literature,12 job stress models are identified. These stress models are analyzed along the two dimensions of focus and theoretical foundation. The analysis shows that most of the job stress models consider stress to be the consequence of the interaction between an environmental stimulus and the idiosyncratic response of the individual. Further analysis of these models suggests that nine key points are critical in developing a theoretical framework of jon stress on IS organization. A mapping of how the existing stress models incorporate the nine key points is also presented. The findings of this paper can provide a theoretical basis for further research on the job stress of IS organization. Finally, an agenda for further research into this issue is presented.

This study is a fundamental research for gifted education model of verbally gifted students. The purposes of this study are twofold: First purpose is to analyze the present position of gifted education for verbally gifted students in Korean. Second purpose is to provide suggestions related to educatian model developing of verbally gifted students. The results of this study were as follow. First, the concept of verbally gifted students must be included the viewpoint of verbal experience. Second, verbally gifted students are learners who have a relative position in education. Third, the purpose of gifted education and the contents of differentiated curriculum for the verbally gifted were analyzed in order to develop education model for verbally gifted learner. Fourth, education of grammr must be included in gifted education as a verbally principle.
Porter의 산업구조분석모형을 이용한 TFT-LCD 사업매력도 분석
