많은 온라인 컨텐츠 회사들이 최근 온란인 광고수입의 한계를 느끼기 시작하면서 자신들의 서비스에 요금을 부과하는 경향이 있어왔다. 이 논문은 왜 온라인 컨텐츠회사들이 왜 자신의 서비스에 요금을 부과를 하게되었는지를 인터넷 시장의 성숙과 관련하여 살펴보고, 기존의 오프라인 컨텐츠회사들이 온라인시장에 진입시에 따른 전략을 고찰한다. 또한 온라인컨텐츠 시장에서의 가격전략과 관련된 시사점을 논의한다.

In this research, we analyzed the influence factors and introducing outcomes empirically. The influencing factors over IT Outsourcing set up organizational factors(maturity of information system, the support of CEO), dealing factors(asset speciality, uncertainty, degree of using of information system), and risk factors(risk of safety/security. cost increase, loss of autonomy). The result of this study are as follows. In the organizational factors, degree of a maturity of the information system and the support of CEO were analyzed as the variables affecting the introducing outcomes positively. In the dealing factors, however, the degree of using information system was only analyzed as the variables affecting the introducing outcomes positively, while the speciality of asset and the uncertainty factors were analyzed as the variables not affecting the introducing outcomes. In the risk factors, the risk of safety/security and the increase of cost were only analyzed as the variables affecting the introducing outcomes positively, therefore loss of autonomy, was not analyzed as the affecting variables.

Estimating levels of user trust is important for maintaining continuous use of e-commerce systems because trust alleviates user concerns about the invisibility of service providers or their reputation. Conventional trust estimation approaches such as policy-and reputationbased reasoning have focused on the experience of e-commerce systems at an early stage. However, only a few trust reasoning methods have considered the mature stage, which is more related to continuance intention. We propose a trust reasoning method dedicated to the mature stage of using e-commerce systems. In particular, a new method of unobtrusively estimating the degree of user intimacy is developed, because intimacy has been highly associated with trust as well as reputation. Our experiments show that the proposed method is valid and can be used in conjunction with reputation-based trust reasoning.

Recently many Hotels have implemented and operated the Hotel Information System(HIS). These HIS-implementation evoke the significant changes in hotel management. So many interest and researches in HIS has received the spotlight from the hotel managements. Many researcher about HIS focused on the Critical Success Factors (CSF) from the viewpoint of HIS implementation. At this moment we need also the research about significance change of CSF with the laps of time. This kind of research are very critical for the successful operation of HIS. To achieve the objectives of this paper, the Innovation-Theory of E. M. Roger was implemented. As the result of this research we can get the various maturity point of each CSF with the laps of time. For the data gathering many major hotel in Korea were interviewed, and 84 valid questionaires were used for data analysis. The Cronbach's ${\alpha}$ was 0.7239, which means all data were significant.

The timing of hydrocarbon generation and expulsion from source rocks can be evaluated by reconstructing the geohistory of the basin using petroleum system modeling. The Tyee basin is generally considered having a high hydrocarbon generation potential For the southern part of the basin, the basin evolution from a structural and stratigraphic points of view, the thermal history, and the burial history were reconstructed and simulated using numerical tools of basin modeling. An evaluation of organic geochemistry for the potential source rocks and the possible petroleum systems were analysed to improve the understanding of the hydrocarbon charge of the basin. Organic geochemical data indicate that the undifferentiated Umpqua Group, mudstones of the Klamath Mountains, and coals and carbonaceous mudstones in the Remote Member and the Coquille River Member are the most potential gas-prone source rocks in the basin. The relatively high maturity of the southern Tyee basin is related to deep burial resulting from loading by the Coos bay strata. And the heating by intrusion from the western Cascade arc also affects to the high maturity of the basin. The maturation of source rocks, the hydrocarbon generation and expulsion were evaluated by means of basin modeling. The modeling results reveal that the hydrocarbon was generated in all potential source rocks and an expulsion only occurred from the Remote Member.

본고에서는 전력계통 운전에서 대단히 중요한 분야인 신뢰도 제어분야에 대한 전문가 시스템의 적용에 대하여 현재까지의 연구상황과 적용사례를 소개하고 당면 연구개발 과제와 장래 전망을 간단히 기술하였다. 전문가 시스템 연구는 일본과 구미각국에서 활발히 연구되고 있으며 매년 수십개씩의 특수전문가 시스템 개발용 쉘(Shell)이 상품화 되어 쏟아져 나오고 있으며 전문가 시스템 개발용 Tool도 컴퓨터 소프트웨어 관련 회사들이 경쟁적으로 개발 보급하고 있는 상황이므로 수년내에 전문가 시스템의 활용도가 기존 프로그램 활용도와 비슷한 수준으로 급속히 성장할 것으로 예상된다. 전문가 시스템의 응용은 모든 산업분야에 걸쳐 광범위하게 적용될 수 있을 뿐만 아니라 기술집약적 두뇌산업분야에 걸쳐 광범위하게 적용될 수 있을 뿐 만아니라 기술집약적 두뇌산업이므로 국가전략산업으로의 육성이 시스템 응용을 위한 한미 워크숍이 개최되어 양국의 활발한 기술교류가 이루어졌으며 국내외적으로 연구분위기가 성숙되어 있는 만큼 국내에서도 전력계통 신뢰도 제어분야에도 전문가 시스템 도입을 위한 연구가 활성화 될 수 있길 바라는 바이다.

전자상거래 시스템에 대한 관심이 고조되고 있다. 언론의 보도에 따르면 전자상거래 시스템을 운영하는 기업의 매출이 지속적으로 늘어나고 있다고 한다. 전자상거래 문화가 성숙해 가고 있는 것이다. 그러나 이러한 전자상거래 시스템들은 시간이 지날수록 고객의 지속적인 요구와 환경의 변화에 따른 유지 및 보수 즉 업데이트의 문제에 직면하게 된다. 현재 이루어지고 있는 비즈니스 로직과 프리젠테이션 계층의 통합에 따르거나 페이지(Page) 개념에 준한 시스템 설계나 구현은 EC시스템의 지속적인 성능 개선을 어렵게 하고 있다. 이에 따라 본 연구에서는 이러한 문제를 해결하기 위한 수단으로서 MVC모델에 기반한 JSP Model 2 구조를 적용하여 EC시스템을 구현하고자 한다.

Recently, the demand against the system risk analysis and security management from the enterprises or the agencies which operate a information system is increasing even from domestic. The international against the standardization trend of information protection management system it investigates from the dissertation which it sees. It analyzed and against information property information protection management system integrated it will be able to manage a danger modeling it did it proposed. Having analyzed as well as compared the matureness of security-measurement models in regard to the global standard of proposal system, the administrative presentation for various IT technology resources. which have been managed singly so far, is now well applied under the united control of the company itself, and enabled the automated management of authentication support and renewal for ISO 27001, ISO 9000, ISO 14000, resulting in much advanced operation for both material and human resources.

The choice of occupation has a great deal of influences on achievement of self-realization and living a good life in an individual's life. Especially, it is very significant for Elementary school students because they become to aware of career and develop. However, in the present, the career guidance is mainly concentrated in the solitary work, such as an aptitude test and printed materials. The perspective from the student, therefore, needs systematic and efficient system to accumulate activities and result of their various career guidance for individual career-related information. The system to improve elementary school student's career awareness based on e-portfolio has been developed. The developed system can effectively accumulate students' activities and result of their various career guidance and easily grasp their strengths and weaknesses of intelligence based on theory of multiple intelligences. Teacher also can easily grasp their student's talent through all sorts of graphs provided by the web site for career education.
