정부는 산업과 무역 전반의 전자상거래 시스템 구축과 공공부문에 전자상거래를 조속히 도입하여 경제전반의 전자상거래를 선도하고 공공부문의 효율성과 투명성을 제고하기 위하여 2000년 2월 전자상거래 활성화 종합대책을 수립하여 추진 중에 있다. 그러나 건설산업의 전반적인 전자상거래는 아직 미흡한 실정에 있다. 정부의 주도로 대형 건설업체들은 IT투자증대와 컨소시엄을 구성하여 E-marketplace를 구축하고 있으나 중소 건설업체들은 전자상거래에 대한 투자가 어려운 실정이다. 따라서 본 연구는 국내 중소건설업의 환경과 전자상거래의 제도적 측면에서 문제점을 검토하여 국내 중소건설업의 경제적 지원측면에서 전자상거래 관련 세금감면법규의 한계성을 분석하고 중소건설업 대상 설문조사를 통하여 정부의 전자상거래의 활성화 정책에 있어서 정부유도정책의 필요성과 전자상거래 활용도에 대한 인센티브 부여의 필요성, 그리고 그에 따른 대책방안을 제시하였다.

A balance between production and degradation of reactive oxygen species (ROS) is critical for maintaining cellular homeostasis. Increased levels of ROS during oxidative stress are associated with disease conditions. Antioxidant enzymes, such as extracellular superoxide dismutase (EC-SOD), in the extracellular matrix (ECM) neutralize the toxicity of superoxide. Recent studies have emphasized the importance of EC-SOD in protecting the brain, lungs, and other tissues from oxidative stress. Therefore, EC-SOD would be an excellent therapeutic drug for treatment of diseases caused by oxidative stress. We cloned both the full length (residues 1-240) and truncated (residues 19-240) forms of human EC-SOD (hEC-SOD) into the donor plasmid pFastBacHTb. After transposition, the bacmid was transfected into the Sf9-baculovirus expression system and the expressed hEC-SOD purified using FLAG-tag. Western blot analysis revealed that hEC-SOD is present both as a monomer (33 kDa) and a dimer (66 kDa), as detected by the FLAG antibody. A water-soluble tetrazolium (WST-1) assay showed that both full length and truncated hEC-SOD proteins were enzymatically active. We showed that a potent superoxide dismutase inhibitor, diethyldithiocarbamate (DDC), inhibits hEC-SOD activity.

This paper proposes a new framework for variability analysis in QFD. The proposed framework considers the uncertainty of the information contained in the house of quality chart and analyzes the variability resulting in the outcome. A new framework provides a dominance index and a difference index for each pairwise ECs. The indices are helpful to evaluate priorities of each pairwise EC.

The current economic environmental changes such as globalization, information and opening of the market is calling for or needing the more rapid change of management and/or marketing strategies of the company than they did before to survive in tile borderless international competition. Under this situation, this study focuses on the correspondence strategies of Electronic Commerce which is one of the key elements to overcome or lead the above demands through seeking the problems of the current EC acception and application specially in Chollabuk Do province. For the above purpose, this study surveys the questionary with business firms of above area and figures out what is the correlation between business form and size and EC acception and application and what is the problems on it. And than provides several counter strategies which are following based on the survey to keep this area companies from out of business and lead the above economic environmental changes. To expand the adoption and application of EC to this area, firstly, top managers of the company must recognize the necessity and importance of EC compared with traditional commerce and change their perception and attitude concerning EC positively, and than try to accept it as soon as possible. Secondly, the company need the retained earning to invest to EC and educate their managers and employees with total participation. Thirdly, local government has to improve its attention to EC as a best way or opportunity to reduce and overcome the economical gap and development its economy because EC can remove the physical time or distance and space, scale and capital limitations. Finally, government has to expand and establish information infrastructure such as technical infrastructure(communication and security technology), Functional infrastructure like standard protocol, Organizational infrastructure(interchange agreement, relative law) and social infrastructure to improve efficient electronic transaction which can Increase the company' international compatitiveness under the current economy trend.

Currently, it is not popular to use the STEP based product information in the construction drawing files, in spite of the importance and possibility of using various product data in drawing files on the CALS/EC environment. This paper aims to demonstrate a construction drawing information management system based on ISO 10303/STEP. To achieve this aim, the authors have analyzed the current construction drawing information classification hierarchy widely used for domestic and international, and examined the material data connection mechanism within CAD drawing data, and finally investigated the management systems for construction documentations and drawings in a public companies. Therefore, the expected benefit of the proposed system is that STEP drawing information management will be done standardization and the information of STEP construction drawing can be managed, shared and supported design business through materials data connection.

Esophageal cancer (EC) incidence rates in Kazakhstan were assessed by component analysis based on primary registered cases in 2001-2010. It was found that despite an apparent general decrease in the number of EC patients in Kazakhstan, a potential increase should be evaluated, due to changes in aging as well as the increase in population. Some problems of EC patients' registration were broached with an emphasis on the importance of the expected absolute number and reasons for undercounting in the country. Based on these, ways of improving the recording and registration of such patients in the country were suggested.

The tremendous growth of the Internet, particularly World Wide Web, has resulted in significant changes in commerce environments. Internet has brought significant changes in the economics of marketing channels and has led to a redefinition of industry value chain. Electronic Commerce(EC) has become so important that countries and firms unprepared for this new trend would lose competitive advantages in the coming century of Digital Economy. Despite its importance, current EC markets in Korea are immature and there still exist several barriers to EC development thus excluding business to consumer EC markets. As interest in quality management and its effect on competitive performance has grown, there has been a corresponding proliferation of research. However, the majority of the research on quality management has not evolved in a comprehensive and rigorous fashion, particularly with regard to reliability and validity issues. The purpose of this paper investigates on Vitalization of the Activities of on-line shopping mall under of TQM system in Korea. That would make it possible to remove elements of insecurity and doubt currently felt by many users of on-line shopping mall(internet detail or cyber mall) business. In addition, we tried to find out what factors discourage consumers from using electronic purchasing methods, as well as how perceived quality factors and customer satisfaction when consumers are exposed to the purchase process on the on-line shopping mall business.

Many e-Learning companies are incorporated for the last five years, but most of them are failed or merged by the other company. The main reasons are the absence of competitive strategies and recognition of critical success factors. There are many researches on the critical success factors of Information System (IS) and Electronic Commerce (EC) . We derived e-Learning success factors from the previous IS and EC researches. We classified the success factors into five dimensions, (1) contents management, (2) learner management, (3) business strategy, (4) organizational support and ability, (5) learning management system (LMS), and each dimension has 9 or more success factors measurement items. We surveyed the perceived importance of the success factors from the manager of South Korea e-Learning firms. The paper categorized the items into two or more factors for each dimension by the exploratory factor analysis. Finally, we conducted one-way ANOVA for each success factors by the business model. As a result, there is different importance level for each success factors by the business model. We concluded that each e-Learning company needs different strategies to their business model.
