This paper provides an economic evaluation model for public web services which are mainly operated by government agencies. Though there are various services, this paper focus on services for bottleneck problem solving and management information providing. This paper suggests quantitative and qualitative effects of public web services and evaluates them with I-NET users using e-mail surveys. This Paper mv provide a guideline for the future investment on public web services.

For the evaluation algebra $F[e^{{\pm}x}]_M\;if\;M=\{{\partial}\}$, then $$Der_{non}(F[e^{{\pm}x}]_M)$$ of the evaluation algebra $(F[e^{{\pm}x}]_M)$ is found in the paper [15]. For $M=\{{\partial},\;{\partial}^2\}$, we find $Der_{non}(F[e^{{\pm}x}]_M))$ of the evaluation algebra $F[e^{{\pm}x}]_M$ in this paper. We show that there is a non-associative algebra which is the direct sum of derivation invariant subspaces.

BiNem$^{(R)}$ displays have entered volume manufacturing in 2009. Applications range from e-labels to e-readers. We have developed 6-inch $960{\times}720$ pixels passive matrix BiNem prototypes achieving 40 % brightness and fluid user interface based on partial image / dynamic pointer addressing. Active-matrix addressing is proposed to provide even faster operation.

In order to improve e-Trade service, this paper has deduced impeding factors after review of precedent research on e-Trade and analysis of e-Trade current status. Then an empirical analysis of whether variables deduced are detrimental factors to utilization of e-Trade service has been made on the basis of a research model and relevant hypotheses. The scope of e-Trade service indicated in this paper is limited to use of uTradeHub system. Analytical results for the improvement of e-Trade service clearly indicate that the higher the impeding factor to utilization of the system integration, logistics and customs clearance, marketing and users field, the more necessary the service improvement for invigoration of e-Trade service. However, foreign exchange field does not seem to require attention because SMEs have not active will to do electronic payment through the process of electronic documents.

This paper, which is one of the researches to limit high fault-current, treats the application of an inductive High Tc Superconducting Fault Current Limiter(HTSFCL) to distribution systems. In case that the inductive HTSFCL is applied to distribution systems, this paper presented the usefulness and the commercial possibility of it through computer simulation. If the inductive HTSFCL is established in distribution systems, after fault, it limits fault current effectively within a few millisecond, so it contributes to stability of power distribution system. Especially as the system with the HTSFCL is compared with the system without it, the system is improved in stability.

This paper introduces the public-oriented e-Hub construction for strategic alliances in the B2B virtual community. The public-oriented e-Hub can link with all participating Internet firms on the basis of their business models, and consequently help them share their core competence, management resources, and so on. Based upon this perspective, this paper presents the procedures corresponding with social network analysis for strategic alliances of small and medium internet firms. In addition, this paper tries to analyze the relationships among degree of competition, potential of strategic alliance, and financial performance. The results show that the firms with more easily accepting various strategic alliances make higher financial performance under more competitive environment. This suggests that strategic alliances through the public-oriented e-Hub in the B2B virtual community provide the internet firms with various opportunities.

최근 들어 전자상거래의 개념이 기업뿐만 아니라 모든 유형의 조직체로 확산되어 가면서 전통적인 업무처리방식에서 전자적 업무 처리를 향한 변화를 통해 기업이나 조직체는 새로운 가치를 창출하면서 시장을 확대하는 기회로 이용하고 있다. 본 논문은 이러한 전자상거래의 개념을 디지털 도서관에 적용하여 도서관과 비즈니스 패러다임의 변화에 대한 이해를 바탕으로 도서관 업무와 전자상거래가 연계되는 몇 가지 모델을 제안하였다. 그리고 이중 전자상거래 개념을 자료 구입 과정에 적용시킴으로써 자료 구입 과정에 참여하는 모든 기관을 하나의 마켓플레이스로 통합하고 거래 행위가 이루어지도록 하는 eMarketplace를 구축 논리모델을 상세히 제시하였다.

The objective of this paper is to investigate important factors when one can consider an implementation of global e-trade. This paper in particular intends to derive which factors are significant at information strategic planning stage as well as its evaluation stage. Many works in the global e-trade area have been focusing on narrow research issues related to EDI implementation and trade process automation after trade contracts are legally made. Therefore, more complete and exclusive factors at pre-contract stage should be considered when one can make a strategic plan for global e-trade. Five factors are found to be important for global e-trade planning and those are: (1) corporate strategy, (2)trade process automation, (3)trade information technology & infrastructure, (4)organization & people, and (5)trade information technology utilization. An evaluation framework is developed in this paper and its empirical results are also provided.

This paper's objective is to provide insights about the problems and expansion strategies of electronic trade. Korean small and medium-sized firms have adopted the Internet since the end of 1990s in order to reshape their competitiveness, and it is now being utilized as a major export marketing instrument to develop new customers, save export transaction costs ad facilitate new work processes. However, at present, the use of the internet in the field of trading is limited to the collection of market information, owing to legal, technical and institutional restraints between countries. In addition to that, because firms have the difficulties in making the trade contract through the e-trade system, the negative recognition on its' utility has been spreaded gradually between companies. This is one of the barriers to block the expansion of e-Trade between Korean firms. Therefore, this paper points out the problems of e-trade in the environmental, institutional and strategic view and provides many considerations for establishing the expansion strategy of e-trade by the Korean government and trade supporting institutions.
