Using end-user attitude as intervening variable, this paper proposes a causal model of how environmental factors of EUC influence end-user computing (EUC) success, measured by the degree of IS use. This study identifies unique aspects of the EUC environment and generates key dimensions of end-user attitude appropriate for this context : perceived information quality, perceived design quality, and perceived usefulness. The research model includes six environmental factors - top management support, end-user education, task variability, task analyzability, end-user's computing ability, and end-user involvement. A field study was undertaken to test the hypothesized relationships among the research variables. The results generally support the assumption that end-user attitude intervene the impact of environmental factors on IS use. The implications of the findings are discussed.

In the information age, cheap price of information processing and advances in personalization technology have allowed companies to enhance the relationships with their existing customers and to expand their customer base by effectively attracting new customers. However, most customers are reluctant to provide their personal information to companies. This study explores the tension between companies' desire to collect personal information to offer personalized services and their customers' privacy concerns. The psychological reactance theory suggests that when individuals feel that their behavioral choice is threatened or restricted, they are motivated to restore their freedom. Therefore, despite the expected benefits from personalized services, customers may perceive the services to be restrictive of their freedom to choose. This adverse effect may undermine the relationships between companies and their customers. We conducted experiments to explore the dynamic roles of transactional and environmental factors in motivating customers to provide personal information. We revisited online privacy issues from the perspective of psychological reactance. For the experiments, we created an online shop and randomly assigned the participants to one of the two experimental conditions-high and low levels of information requirements. The results of the experiment indicate that threatening the free choice serves as a transactional cost in online profiling. On the other hand, the expected benefits of personalization services have positive correlations with customers' willingness to provide personal information. This study explains privacy based on transactional and environmental factors. Our findings also indicate that the environmental factors such as the Internet privacy risk and trust propensity do not significantly affect the willingness to provide personal information when firms required much personal information. Implications and contributions are discussed.

Electronic Data Interchange (EDI) is an important part of interorganizational electronic commerce due to the strategic impact derived from its use. In order to ensure successful implementation of EDI, EDI controls must first be developed. Because they are implemented in an environmental context, the characteristics of organizational environments have a significant impact on EDI controls. The control strategy for the EDI system - formal, informal, and automated controls - should fit certain organizational environments. A research model has been developed to depict the moderating effects of six environmental variables including industry, organizational, and task characteristics on the relationships between controls and implementation. It is shown empirically that the relationships between EDI controls and implementation are indeed affected by these factors. The results can help management design formal, informal, and automated controls in view of their own environmental contexts.

Life-Cycle Engineering(LCE) is a decision-making methodology that considers environmental and cost needs during the product life-cycle. Environmental conscious design and manufacturing has become more and more important and it has been enforced by governmental regulations and used as trade restriction. LCE involves integrating environmental consideration into new product development including design, material selection, manufacturing processes and distribution of the product to the consumers, plus the end-of-life management such as disassembly, material recovery, remanufacturing of the product after discarding it. In this paper, a state-of-the-art survey of LCE is presented.

환경문제는 단순히 개별적 원인 및 단일과정을 통하여 발생하는 것이 아니라 복합적 원인과 영향으로 발현된다. 기존의 환경정보는 개별 구축 목적에 맞도록 수치 위주(통계)로 생산되었으며 더욱이 개별 시스템(국가상수도정보시스템 등 17개)에 관련 인자들이 산재되어 있어 다양한 원인 및 피해를 고려해야 하는 환경문제 해결에 많은 시간과 노력이 허비되어 즉각적 적시적 대응이 이루어지지 않는다. 이러한 한계점과 문제점을 인식하여, 환경공간정보를 통합적으로 제공하기 위한 국가환경지도시스템 구축 및 정책적 활용 방안에 대한 연구를 수행하였다. 첫째, 국내 산재되어 있는 환경공간정보 현황을 분석하기 위해 환경부 실 국, 산하 및 유관기관의 시스템 및 환경공간정보 담당 부서의 총 2,701개 업무 자료를 분석하여 총 275개(비점오염원 관리 확대를 위한 환경정보 구축 등)의 환경정보와 관련된 업무 및 정보현황 자료를 선별하였다. 둘째, 환경정책 수립 및 이행을 지원하기 위해 환경정보 관련 업무 현황을 분석하여 총 64건(백두대간, 정맥 및 기맥 현황 및 보전지역 등)의 국가환경지도시스템 세부 업무지원 주제도를 도출하고, 도출된 업무지원 주제도의 우선순위를 선정하였다. 셋째, 업무지원 주제도 구축을 위한 정보 연계를 위해서 환경부 및 산하 유관기관의 전체 17개 시스템 및 환경 주제도를 분석하였다. 분석 결과 활용 가능한 공간정보 총 1,314개 및 세부 항목 총 39,331개의 공간정보 기반의 활용 가능한 데이터베이스를 선별하고 표준화 방안을 수립하였다. 넷째, 국가환경지도시스템의 실질적 구축을 위한 단계별 이행방안을 제시하였다. 마지막으로 향후 국가환경지도시스템을 기반으로 하는 정책적 활용방안을 제시하였다. 국가환경지도시스템이 효율적으로 구축되면 산재된 환경정보를 공간 정보 기반의 공동 활용 데이터베이스로 구축할 수 있고 또한 환경정책 수립에서 위치 기반의 정량적 정책 수립을 지원할 수 있을 것으로 사료된다.

This study is to find out empirically the success factors on the development stages of e-business in Korean enterprises, to formulate e-business strategy and to decide e-business policy. For this purpose, the study reviews the conceptual framework on the success factors for the development stages of e-business and the data is collected from 304 companies implementing e-business. The study is conducted in three ophases an follows; First, according to this study, the development stage of e-business in Korean Enterprises is between 'Information Access Stage' and 'Core Business Transaction Stage'. Second, four factors comsisted of 29 items derived from factor analysis are named as 'Environmental Adaptation','Customer Relationship management','Marketing' and 'Environment of Organization'. Third, the success factors of first stage(Information Access Statge) include 'Marketing' and 'Environmental Adapotation', the success factors of second stage(Electronic Collaboration Stage) include 'Environmental Adaptation' and 'Environment of Organization' and the success factor of third stage(Core Business Transaction Stage) include 'Environment of Organization'. The results of this study show that; 1) the Korean enterprise seems to be in the Electronic Collaboration Stage of e-business development, and 2) the success factors are 'Marketing' for first stage, 'Environmental Adaptation' for second stage, and 'Environment of Organization' for third stage.

It is important to improve the efficiencies of motors to overcome problems such as decreasing energy reserves and environmental pollution. Superconductors are promising for developing high-efficiency motors. However, superconducting wires must be kept in critical conditions and the AC loss needs to be minimized. In this paper, a design of a superconducting interior permanent magnet synchronous motor (IPMSM) is proposed that reduces the AC loss. The characteristics of superconducting and normal-conducting IPMSMs are compared. The proposed superconducting IPMSM has a low AC loss and a very high efficiency at low speeds.

The availability of Information Technology in geological and engineering geological fields is rapidly increasing in Korea. Especially GIS-based hazard mapping is the most distinctive part to predict a possibility of landslide occurrence. Integrated expert system for tunnel construction is also practically used to manage investigated or designed data and to predict un-known underground geological condition. Computer-based field data acquisition tools are also one of the typical part using information technology including GIS combined with mobile phone in Geological field.
