Computational grids are emerging as a new infrastructure for internet-based parallel and distributed computing. Grid systems are enables the sharing, exchanging, discovery and aggregation of resources which distributed multiple administrative domains, organizations and enterprises. Accounting information service is one of the main obstacles to widespread adoption of the grid. But, most of grid portals do not support accounting information service. In this paper, we design an accounting information service and build a web-based grid portal including account management service and accounting information service.

This paper describes a theoretical model for investigating the relationship commitment of trade portal site 6C's. This research is the first to empirical test the causal relationships in Trade portal site. The relationship commitment for e-Trade portal site are tested here using data from 195 samples. Research methodology used in this study was mainly survey and questionnaire. Structural equation model is used in the hypotheses test. the results support all hypotheses involving hypothesis 1 and 6. The major finding of this paper would be summarized as followed: 1) Perceived relationship commitment of e-Trade site 6C's is positively related to contents, community, communication, customization in e-trade activity level and activity range of trade practical 2) Perceived commerce of electronic trade site is negatively related to the relationship commitment of trade companies. 3) Perceived e-trade site in electronic trade connection is positively related to the re-activity intention. In examining the relationships commitment of the factors, e-trade potal 6C's show in significantly by Contents, Community, Communication, Customization, Re-activity intention, but that show in not significantly by Commerce factor.

세이즈메이커의 사람들은 정보 과잉에 대해 한가지 해결책을 가지고 있다. 로이터 통신의 두가지 연구(1996년의 "정보에 대한 굶주림"과 1997년 "스크린 응시")는 정보과잉이 점점 악화되고 있는 심각한 문제임을 확인시켜준다. 이 문제를 해결하기 위해 사내 소스들로부터의 4,000개가 넘는 기업 소스들을 재구분하고 있는 기업정보포탈(Enterprise Information Potal EIP)인 세이즈메이커는 사내 소스들로부터 나오는 정보를 외부적으로 온라인상에서 이용 가능한 것들과 함께 결합시키고 있다. 그의 분류와 구성, 하이퍼텍스트연결, 콘텐츠 능력의 개인화는 오토노미(자치)의 테크놀로지로부터 나온다.

정보통신의 발전, 특히 무선인터넷 기술과 스마트폰의 보급에 따라 디지털 데이터가 증가하면서, 온라인 빅데이터 개인정보 문제 즉, 개인 민감정보의 온라인 노출과 이로 인한 프라이버시 침해에 대한 우려 역시 높아지고 있다. 본 논문은 포털 서비스를 중심으로 국내 인터넷 환경에 공개된 온라인 빅데이터의 개인정보 침해 현황에 대한 분석을 수행하고 프라이버시 침해 가능성을 평가하기 위한 척도를 제시하였다. 이를 위하여 본 연구팀은 포털 사이트에서 제공하는 서비스 컨텐츠 중 약 5천만건의 사용자 게시글을 수집하여 개인정보에 해당하는 정보를 추출하고, 추출된 개인 정보를 기반으로 각 사용자의 ID가 부분 익명화 되었음에도 개인을 특정할 수 있는 신상 정보가 노출될 수 있음을 확인하였다. 또한 부분 익명화된 ID를 사용하여 서비스간 개인 정보의 연결 가능성과 개인 신상 정보 노출 수준을 반영한 위험도 측정 척도를 제안하였다.

Changes in cholinesterase (ChE) activity, electrophoretic pattern of ChE and histopathologic state on the mice serum, brain and liver by administration of organophos-phorous insecticides were studied. The mice ChE activities on serum, brain and liver decreased by increasing of concentration and time both administration of malathion and DDVP, whereas on serum and brain the activities of the 7 days after administration decreased, and then presented the gradually slight recovery in course of time. The ChE on serum and liver showed many isozyme bands by polyacrylamide gel electrophoresis but several on brain. And isozyme bands disappeared and diffused by administration of organophosphorous insecticides and development of time. The mice liver with administration group of malathion on histopathologic test showed midzonal necrosis between central vein and portal area, and with administration group of DDVP mainly presented portal necrosis on location of potal area.

Internet search engines are used by the majority of find information on the Web. However, Web users can be often dissatisfied with the mistakes in the retrieval of ‘Fashion’ information from the Internet. The purpose of this study is to analyze the ‘Fashion’ category structure in the Internet search engines. There are 2 steps for achieving it: the first, to investigate the structures of ‘Fashion’ categories and then, to analyze the gap between ‘Fashion’ categories defined by them and extensive ‘Fashion’categories, which are approached on 2 sides of the fashion-life and fashion-business. We select 5 major search engines for the case study: Yahoo, Lycos, Naver, Hanmir, Empas, which ranked as top 5 of total search engines and potal sites in February, 2001, and retrieve ‘Fashion’ categories from the first level to the last level by using both “topics retrieval”. Eventually, we can find the problems of ‘Fashion’ category structure in search engines. Also, it is concluded with a brief perspective of ‘Fashion’ categories in the Internet search engines and the implications for the future.

This research studied the interactions of online communities, reward, commitment and loyalty to purchase intention in portal sites based on relevant theories. Data were collected from the users who had purchase experiences in potal sites to analyze the effects of interactions and loyalty. An empirical analysis regarding the hypothesized structural equation model was performed using SPSS 10.0 and PLS Graph 3.0. As the result, the interactivity of communities was found significant to commitment and loyalty, the reward of community was shown to significantly influence commitment, but not loyalty. And the commitment and loyalty of community were shown to have much effects on purchase intention. Finally, trust on portal sites were found to have an interaction effect on purchase intention.
