The digital government is one of the most significant areas of study to emerge in information science in the past several years. The digital government is, in broad terms, a computerized system that allows a community of users to obtain a coherent means of access to an organized, electronically stored repository of information and knowledge. The information resources and technologies embodied by the World Wide Web are now accepted ad the primary example of the digital government. The need exists for a means to measure user success in the digital government. Because a digital government environment involves two broad functions?1) information search and retrieval and 2) interactivity with and through the medium-this research posits that measures of both of these functions will show positive correlation with user success.

With the increase in amount of data and information available on the web, there have been high demands on personalized information retrieval services to provide context-aware services for the web users. This paper proposes a novel dynamic multi-agent context-awareness user profile construction method based on ontology to incorporate concepts and properties to model the user profile. This method comprehensively considers the frequency and the specific of the concept in one document and its corresponding domain ontology to construct the user profile, based on which, a fuzzy c-means clustering method is adopted to cluster the user's interest domain, and a dynamic update policy is adopted to continuously consider the change of the users' interest. The simulation result shows that along with the gradual perfection of the our user profile, our proposed system is better than traditional semantic based retrieval system in terms of the Recall Ratio and Precision Ratio.

High tech companies' strategies are divided into four parts, Market Pull, Technology Push, Market-Driven, and Driving Markets. Market Pull strategy means to search market-needs, chances or new industries with technological chance. Technology Push means to create new market by new technology. While Market driven companies follow market changes, Driving Market companies make or change their markets. This study analyzes how companies recognize their market situations based on technology and which business inclination paths are selected for success. And we would like to know there are performance distinctions based on market differentiation strategies.

Oligopoly differs from perfect competition and monopoly in that a firm must consider rival firms' behavior to determine its own best policy. This interrelationship among firms is the issue examined in this paper. In the oligopoly market, the complete information market means that each producer has full information about itself, the market, and its rivals. That is, each producer knows the market demand function, its own cost function and the cost functions of rivals. On the other hand, the incomplete information market means that in general each producer lacks full information about the market or its rivals. Here, we assume that each firm doesn't know the cost functions and the strategic biddings of its rivals. The main purpose of this paper is to analyze firm' strategic behaviors and equilibrium in an electricity market with incomplete information. In the case study, the complete information market and the incomplete market are compared at the Nash Equilibrium from the viewpoints of market price, transaction quantities, consumer benefits, and Social Welfare.

Purpose - The purpose of this study is to explore how advertising for multilevel marketing brands affect the salesperson's activity including customer-salesperson interactivity, work attitude, and perceived and actual performance after the campaign. Research Design, data, and methodology - This study collects experimental data, survey data, and actual sales data and applies statistical analyses such as factor analysis, t-tests, and a structural equation model. Results - The results show that advertising campaign can enhance a salesperson's selling activities and provide wide managerial implications to a multilevel marketing firm by filling the gaps for the field of advertising research. Conclusions - Managerial implications include: i) multilevel marketing firms should consider advertising campaigns as a means of changing customer responses because advertising plays a significant role in increasing familiarity with, and knowledge of, attitudes toward the brand, which also helps salespeople interact with customers; ii) multilevel marketing firms should consider brand advertising as a means to support the sales activities of salespeople including sales effectiveness, work attitudes, and perceived performance, and iii) multilevel marketing firms should consider brand advertising as a means to enhance a salesperson's pride and motivation for selling their brand, which will lead to improved sales performances.

본 연구는 오랜 기간 동안 난항을 거듭해왔던 한 사례를 통해 지방정부의 정책추진과정에서 갈등관리능력이 차지하는 중요성을 부각시켜보고자 하는 목적으로 시도되었다. 본 연구가 주목한 사례는 지난 1991년 입지선정에서 시작하여 무려 20년이란 긴 세월 동안 정책추진의 난항을 거듭해오다가 최근에 이르러서야 해결의 문턱을 넘어 비교적 안정적인 정책추진의 기미를 보이고 있는 경기도 남양주시의 쓰레기 소각잔재 매립장 건설사례다. 유사한 입지선정 및 건설과정의 갈등을 겪었음에도 불구하고 상대적으로 짧은 기간 내에 성공적인 정책추진을 경험했던 기타의 많은 지방정부 사례와 달리 남양주시 사례의 경우 장기간 동안 대립적 상황을 거듭해 왔던 점은 갈등관리의 차원에서 주목해 볼만한 특이사례다. 과연 남양주시는 왜 정책추진에 그토록 오랜 세월을 허비하며 난항을 거듭해 온 것일까? 본 연구는 일정한 분석모형에 입각하여 정책 성패요인의 인과관계를 검증하는 연역적 접근과는 달리, 정책단계별 사례의 개요와 쟁점 및 구조를 기술하는데 치중함으로써 정책단계별 갈등관리의 중요 요소를 귀납적으로 추론해 나가는 방식을 취했다. 분석 결과, 지방정부의 정책추진과정에서 갈등관리는 정책수립 및 결정단계와 홍보단계 그리고 집행단계에 이르기까지 지속적인 민주적 절차와 토론 및 주민과의 협력을 도출하기 위한 노력을 요하는 연속적 과정임을 확인할 수 있었으며, 이는 궁극적으로 정책성공의 중요한 요인으로 작용하고 있음을 확인하고 있다.

This paper aims to construct and analyze the domestic collaborative research network in industrial engineering. Using co-authorship information contained in the papers published in the two journals of the Korean Institute of Industrial Engineers, the collaborate research network at the institutional level is constructed. The core institutions in the network are identified by means of the centrality indexes of social network analysis. In addition, the five types of roles of the institutions in industry-university-institute cooperation are examined through brokerage analysis: coordinator, consultant, gatekeeper, representative, and liaisons. The findings are expected to be fruitfully utilized in formulation of R&D strategy of relevant organizations and technology policy making for promoting collaborative research in industrial engineering.

This study extensively investigated Japan's FTA strategy and plan of FTA policy and analyzed the economic effect caused by it. In the analysis of economic effect using world economical model shows not only positive economic effect in home country but also to the foreign country. Recently, Japan's bilateral relation with Korea and China is getting worse, not in a friendly way. Consequently Japan's future FTA negotiation will be expected to be focused on the East-Asia region. In other words, Japan expressed assistance for the purpose of communication, stability and prosperity in the East-Asia and will seek individual economic cooperation with each East-Asia country trying to reinforce the stand of Japan. This means that Japan is trying to improve the relation with Korea and China in the other way because it cannot change the relation with Korea and China on its own. That is to say, It can be interpreted as Japan is trying to reinforce the economic cooperation with other East-Asia countries for the realization of East Asia community rather than directly negotiating with Korea or China.

The complexity of information and communication policy has been increasing due to its rapid changes and its expansions toward various fields. I used the2001, 2002 and 2003 White Papers on MIC(Ministry of Information and Communication Republic of Korea) as a reference and the Vensim PLE program to create a causal map. According to my analysis, no major feedback loop was found among the information and communication policies. Thus, it was impossible to conduct a causal map analysis on these policies. The causal map analysis is usually employed to understand a complex mechanism of entire policies by finding feedback loops among them. A lack of feedback loops makes it impossible to conduct the causal map analysis and means that the mechanism of such policies is even more complex to understand. The most important conclusion is that to consider feedback thought among the policies based on the systems thinking before making the policies.
