Consumers have been requiring more higher level of food and agricultural products safety. The system of Good Agricultural Practice(GAP) has been spreaded over the world. Korea also introduced the GAP system in agricultural industry. GAP is related to the production side in the whole traceability system. The establishment of GAP system is a prerequisite to secure food safety. This study reviewed the concept of GAP and necessities and backgrounds of introducing the GAP system. Also, this study analyzed the problems which have been appeared in the GAP program and proposed the policy strategies and directions for the Korean GAP system. So issues for the GAP system are as follows; computerizing of traceability system, forming the cooperative works among the related governmental departments, establishing a certification system to relate with crop features, efficient management, ensuring distribution channel and the research for estimating GAP consumer surplus is need to analyze GAP program more efficient. In addition, It is necessary to keep the records of the data to analyze the GAP program more accurately.

In 1990s, interest on Environment has been increased and Environment-oriented consumer's economic power accelerated the trend of preference for 'Environment-friendly material'. Moreover, the concept of 'Sick Building' Syndrome has been spread to the public and solution for the syndrome is required. 'Environment-friendly material'means that the material used is not harmful for the user's health, and on top of that, causes least harm to the environment during production/scrap process of the material itself. Decision of designers and architectures, as a result, is really crucial tot he environment issues. Above all, selecting the most environment-friendly material and design among possible candidates is natural and cost saving way. In the paper, couple of Evaluation Criterium for Material Selection are analyzed and objective linkage has been identified. With the result of analysis, methodology to minimize damage on environment during whole life cycle of the Interior Design has been sought for.

The purpose of this research is to analyze perceptions of consumers and willingness to play for high-priced food. The price dispersions of four food categories - soybean sprouts, tofu, milk, and egg - were analyzed through the market analysis, and the survey with the structured questionnaire was utilized to get information on the reason why consumers buy and don't buy the high-priced food. It tested whether a consumer would change the choice if the new product information on safety issues is offered and if the price of high-priced food is lowed. Results showed that generally consumers don't have the confidence on the level of safety and comparative advantages of quality of high-priced food, but they just purchase the high-priced food as long as they can afford it.

Household work is a productive activity, but it was not included in the System of National Accounts(SNA). Feminists and household economists complained this drawbacks of the SNA frequently. Finally, a Satellite Account for household production was allowed in the 1993 SNA. Korean government aimed to develop a Satellite Account for Korean household production. However, the development process u3s not efficiently peformed because of the lack of interests, relevant research, and appropriate dat3 at the national level in Korea. Therefore, this study aimed at examining to develop the Satellite Account for Korean household production in terms of its concept, method, data collection, and research topics. Several issues were discussed including methodology to value household production economically, appropriate ways for data collection, and future research directions in the topics of a Satellite Account.

The purpose of this study is to review the characteristics of the policy for supporting child care and education in Korea. In order to suggest the theoretical and practical issues for child care and education policy, it is necessary to evaluate the existing policies. Based on the review of the literature, the legal system, and the policy, the child care support system in Korea is evaluated to be fragmentary and inconsistent. And Korean child care policy is a mixture of the conservative and the liberal one. In order to meet the needs of the family and children of Korea, more progress approach to child care policy is needed. The suggestions of this study are to have Korean government give more weight on societal care of children, introduce children's allowance, integrating child care and education system and developing policy monitoring systems in Korea.

Service science has emerged as the key factor in developed economies as it becomes the main driver of productivity and economic growth. MICE industry has also opened up new revenues through improved services and new services which is a more attractive strategy for success. The importance of adoption of service science has recently emerged in MICE industry. However it has not been provided a detail action plan it is needed positive interesting and common endeavor of academy, industry, and government sector. In this context, we analyzed the major issues in adoption of service science in the MICE industry and developed the paradigm model by ground theory approach and proposed a roles of MICE service provider, mediator and consumer for service science adoption which have not been treated as a research topic in the domestic MICE areas sofar.

The growing concerns on environmental protection have been constantly demanding cleaner and more energy efficient vehicles without compromising any conveniences provided by the conventional vehicles. The recent significant advances in proton-exchange-membrane (PEM) fuel cell technology have shown the possibility of developing such vehicles powered by fuel cells. Several prototype fuel cell electric vehicles (FCEV) have been already developed by several major automotive manufactures, and all of the favorable features have been demonstrated in the public roads. FCEV is essentially a zero emission vehicle and allows to overcome the range limitation of the current battery electric vehicles. Being motivated by the laboratory and field demonstrations of the fuel cell technologies, variety of fuel cell alliances between fuel cell developers, automotive manufactures, petroleum companies and government agencies have been formed to expedite the realization of commercially viable FCEV. However, there still remain major issues that need to be overcome before it can be fully accepted by consumers. This paper describes the current fuel cell vehicle development status and the staggering challenges for the successful introduction of consumer acceptable FCEVS.

Competition among electric generation companies is a major goal of restructuring in the electricity industry. In electricity market, a huge volume of commodities will be traded through competitive bidding. The choice between uniform and pay-as-bid pricing for electricity auction has been one of most important issues in deregulated electricity market. This paper proposes a constrained Bertrand model for analyzing the electricity auction market of price competition model. The issue of the two pricing rules of uniform and pay-as-bid is studied from the viewpoint of consumer's benefit. This paper also shows that transmission congestion depends on the pricing mechanism. Pay-as-bid pricing gives less possibility of transmission congestion by price competition, and less burden to consumers in the simulation results.

Less power consumption, lower cost, smaller size and more functionality are the increasing demands for consumer electronic devices. The three dimensional(3-D) TSV packaging technology is the potential solution to meet this requirement because it can supply short vertical interconnects and high input/output(I/O) counts. Cu(Copper) has usually been chosen to fill the TSV because of its high conductivity, low cost and good compatibility with the multilayer interconnects process. However, the CTE mismatch and Cu ion drift under thermal stress can raise reliability issues. This study discribe the thermal stress reliability trend for successful implementation of 3-D packaging.
