현재 인터넷상의 개인미디어로 각광 받고있는 블로그는 개인의 일상적인 정보라는 기본적 기능에서 사용자에게 빠른 속도로 사용이 전파되기 시작하여 그 영역을 확대해 기업 마케팅 채널의 일환으로 시장에 급격하게 수용되고 있다. 본 연구에서는 문헌연구를 통하여 블로그의 개념을 이론적으로 파악한 후 어떤 기술적인 특징을 가지고 마케팅 분야에 활용되는지를 고찰하였다. 이어서 블로그 본연의 개인적인 공간이라는 영역을 최대한 부각시키면서 블로그 상에서 전자상거래를 구현할 수 있는 논리적인 방안을 제시한 다음, 블로그 기반의 Yard-Sale시스템의 데이터베이스와 구성물(Class)의 설계, 이에 기반한 아키텍쳐의 실제적인 구현과 운영을 수행하였다.

유비쿼터스 컴퓨팅 환경에서 중요한 요소중의 하나는 안정적인 컴퓨팅 환경을 유지하는 것이다. 그러기 위해서는 사용하고 있는 시스템의 정보를 실시간으로 보여주어 사용자로 하여금 모니터링 할 수 있게 해줄 필요가 있다. 그와 동시에 사용하기 쉬우면서 정확한 기능을 수용하여야 한다. 이런 요구사항을 수렴한 리눅스 기반의 시스템 모니터링 프로그램을 개발하였다.

The ERP System is used as a useful tool for corporate management. The ERP system needs to be researched for continued use, taking into account the mandatory acceptance environment. This study was validated through AMOS 18 by setting up a model that adds variables in the mandatory acceptance environment based on prior studies on factors affecting the intended use of ERP system. Analysis shows that the intended use of ERP system users is significantly influenced by user satisfaction and objective usefulness, and that user satisfaction and objective usefulness are significantly affected by the quality of service quality of service. This study suggests that it is important to make users to feel the usefulness and satisfaction of the system through user's prior knowledge and participation. It also says that there is a need to maintain service quality.

u-Park means national parks with environmentally sound information networks and integrated ubiquitous services are available. u-Park is totally managed based on u-IT (Ubiquitous IT Technologies) which provides ubiquitous service through sophisticated resources of national park and establishments. It is necessary in changing the existing park management system into u-IT based u-Park management system that park managers should accept new technology, u-Park management system, and be able to utilize it. The purposes of this research is to analyze managers' acceptance behavior on ubiquitous computing technology. Technology acceptance model (TAM) was introduced to specifies the causal relationships among variables related to managers' technology acceptance behavior. The hypothesized model was tested by surveying 157 managers at 5 national parks in Korea. TAM accounted for 55.2% of the variance in intention to use. The most important finding is that perceived compatibleness was the most influential variable in determining intention to use. This means that u-Park management system should be compatible with manager's task and business style.

In the radical char]go of the business environments that the existing facilities can not guarantee the business-frosts anymore, enterprises have been importing ERP system. In Korea, Sam-sung Electronics did it for the first tin in the latter half of 1994 and other enterprises succeeded. Currently, government and public enterprises as well as most of the large enterprises are employing ERP system to sharpen the competitiveness and to win the business transparency. On the other hand, it is harder for small and medium enterprises shaded by the large enterprises to be well-equipped with information system such as ERP, because they have already suffered from chronic financial difficulties and shortage of many resources. Most of all, they prefer the short-term project that does not need much tine for them to make decisions and to carry out fully. Grounded on the above factors, in this work, I suggest the suitable ERP model for the small and medium enterprises and the successful importing process of ERP, which is derived from the previous researches made by other masters' thesis. If necessary information and human resources are interchanged pertinently between local education institute and small and medium enterprise, the latter could not only deal with the confronted difficulties successfully inside and outside but attain the goal of being proficient in up-to-minute high technology. Besides, giving the students the opportunity of researching into the practice of the business they have not ever known, local universities could help their students accumulate knowledges and acquire ideas which could not be achieved in pure academic studies. When the above-mentioned procedure is over, the students might get the intellectual faculty to ponder on the future more concretely and enter a profession more carefully. In the result, we would raise up the percentage of the employment among the graduates. And active participation of university professors is the last important factor that assists the small and medium enterprises for introducing ERP system successfully. Their scholarly attainments play an important role in strengthening local economy and make the business competitiveness balanced between the capital and the local economy.

Vendor Managed Inventory(VMI) is a distribution channel system where the inventory at the retailer is monitored and managed by the manufacturer or vendor. By pushing the decision making responsibility further up the supply chain and centralizing the replenishment decision, the vendor can help the entire supply chain be more competitive. The purpose of this research is to explore the factors influencing the adoption of VMI by Korean manufacturers. This research proposes the IT readiness, operating cost, and information sharing as antecedents of burden for VMI, and collected the survey responses from the small-to-medium manufacturers. The statistical results indicate that only the operating cost has a significant impact on the adoption of VMI. However it has also been found that the IT readiness and information sharing have a significant effect on the operating cost. Thus indirectly influence the adoption of VMI. As a conclusion, the academic and practical implications of these findings are discussed.

In distributed office, the pairs can program together using a distributed pair programming system. Many CSCW tools featuring remote screen sharing function have insufficient usability, accessibility to introduce many developers to distributed pair programming. In this paper, we suggest a distributed pair programming system based on IDE, which many developers will accept and use easily. We have do#eloped a user scenario and GUI of the system, making distributed pair programming easier and designed with high extensibility by adapting design patterns and implemented in Java language. Our findings will be of significant help to developers dealing with implementation of distributed pair programming function into some commercial IDE.

As the development of wireless technologies continue, mobile stock trading has become a new channel for companies to reach their customers. This study examines the factors affecting customer acceptance of mobile stock trading services. The research model based on the previous studies was established and the research hypotheses were generated. The sample was divided into users and nonuser groups. The test results show that relative advantage and social influence are positively related to intention to accept mobile services as well as in intention to reuse, security risk is negatively related to intention to reuse, frequency of trading is positively related to intention to reuse, cost burden is negatively related to the probability of using mobile stock trading services, and social influence is positively related to the probability of using mobile services. The results also support that information quality and response time are positively related to relative advantage, and interface quality is negatively related to complexity. It is considered that the study results may help managers to increase customer use of mobile stock trading services.

In this paper, we propose a novel behavioral model that explains the use of the military battlefield management system more effectively in the non-voluntary use environment. This study intends to suggest a model based on the Unified Theory of Acceptance and Use of Technology(UTAUT), an extended TAM. Also, it introduces the concept of 'Conative IS use' as a dependent variable that can explain user's behavior more effectively in non-voluntary technology acceptance environment. In addition, we propose the major factors affecting the UTAUT components from the TOE(Technology-Organization-Environment) perspectives, and analyze their effects. In order to validate the proposed model, this study applies PLS(Partial Least Squares) to the survey collected from military personnel. The findings of our study may shed a light on improving the effectiveness of battlefield management information system.

본 논문에서는 MPEG 스트리밍 시스템에서 실시간 미디어 필터링을 통하여 제한된네트웍 대역폭에서 미디어 서비스의 실시간 특성을 만족시킬 수 있는 소스 서버와 필터링 서버를 구현한다. 전형적인 스트리밍 시스템에서는 고정 대역폭에 근거한 사용자 수용 제어 정책을 사용하기 때문에 인터넷의 이형성 특징인 가변 대역폭에 대한 QoS 서비스 정책이 미비하다. 미디어 필터링에 의한 스트리밍 시스템은 동적으로 QoSf를 변경하기 때문에 다양한 서비스 정책을 지원할 수 있다.
