In the aftermath of nation-wide controversy over "conservation vs. development" of the costal wetland in the Saemangeum, Korea could legislate the laws of wetland conservation and costal management in 1998. Since then, the public interest in the costal mudflats and its conservation has increased greatly, but the controversy on the economic value of mutflat wetland and the futher (un)necessity of reclamation) is not yet settled. In the cases of Korea dealt, economic valuation of wetland was performed mainly in the milieu of reclamation(development) vs conservation conflict, or from interest of recreational use. Korean studies used to estimate economic value of development case and conservation case respectively and then tried to compare these two value, as is sometimes done also in other countries. But the scrutiny of the results of these studies leads us to conclude that the revealed wide discrepancy among estimated values, above all other methodological problems, denies any practical applicability to the actual policy use. Benefit transfer as a convenient alternative method of valuation can not be usable either in our cases, because there is too few reliable estimated economic values of mudflat wetlands.

The purpose of this study is to investigate the effect of College Students' Ego Status on career aspiration and job choice value. In order to investigate this questionnaire, 120 students from the Tourism Management Department of S University in Gyeonggi-do were surveyed. The questionnaire was reconstructed on the basis of previous studies and total of 45 items. Survey items of career choice value were 7 items including leadership desire, professionalism, direct improvement, social contribution, intellectual value calculation, vacation guarantee, salary Level. As a result of the study, it was found that career aspiration and job choice value were highly correlated with each other and that egogram structure showed a high correlation with adult ego status. Also, the higher the career aspiration and the higher the adult ego status, the higher the value of job choice. Based on the above results, the analysis of the ego-status profile based on the transactional analysis theory can be used as a very useful basic data for exploring the students' career decision, career choice and job choice, I think it will help me to understand and find an alternative career path.

This study tested relationship between consumer's motivation for mobile shopping and their value of shopping, satisfaction, and repurchase intention. The result of the analysis deduced four factors in motivation for mobile shopping-: ubiquity, convenience, impulsiveness, and economic feasibility. The results indicated that motivation for mobile shopping and consumers' value of shopping have a significant influence on each other. Specifically, impulsiveness had a considerable influence on hedonic shopping value, whereas convenience had a significant influence on utilitarian shopping value. In addition, motivation for mobile shopping and value of shopping had a significant influence on consumer satisfaction and repurchase intention. To put it concretely, among the motives of mobile shopping, ubiquity is found to be the factor influencing consumer satisfaction and repurchase intention the most. Lastly, consumers' shopping value influences consumer satisfaction and revisiting intention significantly. This result provides useful base data for establishing distinctive marketing strategies in the rapidly growing mobile shopping market.

한국의 대학수학 교육에 대한 여러 종류의 관심이 다양한 현실적 필요성에서 대학의 수학 교수들 사이에서 일고 있다. 대학수학 교육의 어떤 연구 주제를 누가 어디에서 어떻게 연구하여야 연구로서 가치, 타당성 그리고 연구 결과를 유용하게 활용할 수 있는지 등 연구의 방향, 목표, 그리고 결과의 활용에 대한 적절한 합리적 준거틀에 대한 논의가 부족한 실정이다. 일반적으로 수학교육에 대한 연구 결과는 실제 수학 수업을 수행하는 교수, 교사 또는 교육행정가에게 유용한 정보, 지식 그리고 수업 수행 방법(기술) 등을 제공하여 그들의 의사결정 문제를 결정하도록 적절한 도움을 줄 수 있는 유용성을 가져야 한다. 학교수학 교육은 국가적 교육과정을 갖고 있다 이에 비하여 대학수학 교육은 각 대학마다 다른 교육 환경과 목표를 반영한 대학교육과정에 대학수학 관련 교과(강좌) 또는 수학전공 교과들이 포함되어있다. 다양한 대학교육 환경과 시스템에 놓여있는 대학수학 교육의 상황 또는 현상을 개선하기 위한 연구의 수행 원칙과 질적 기준들 무엇인가?를 논하였다.

연구 개발자들은 자신의 정보활동에 있어 전체 활동의 20 ${\sim}$ 40%를 관련 정보의 탐색 및 분석에 사용하고 정보활동 결과는 개인 컴퓨터에 저장한다. 그러나 개인 컴퓨터상의 유용한 정보는 정보관리 및 공유 도구의 부재로 인하여 가치 및 유용성을 상실하고 있다. 본 연구에서는 데스크 탑 서치와 P2P 기반의 정보공유 기능을 갖는 시스템을 제안한다. 데스크 탑 서치를 통하여 연구 개발자는 본인의 컴퓨터에 저장된 정보를 효율적으로 활용할 수 있다. 연구 개발자들이 많은 시간을 들여 축적한 유용한 정보자원을 쉽게 공유할 수 있게 하는 P2P 기반의 정보공유는 연구개발 활동의 전체적인 생산성을 높일 수 있다.

Subacute Ankle Sprain patients, 3 tests have been acknowledge for diagnostic precision and thus most commonly used to test their soft tissues, muscles, and ligaments: ankle stress-valgus test, anterior-draw test, and MRI scan. Although not much different from the rest two in its diagnostic value, MRI costs patients some money and time. Also, we have reached the conclusion through an experiment with a group of patients in a certain hospital that the rest two methods is as efficient and useful as MRI in diagnosing ankle joint patients.

The purpose of this study is to analyze the effects of Logistic Information System on performance by efficiency of internal operation and organizational innovation. The results of this study as follows : The characteristic variable evaluation model that extended from the performance(user's value, perceived usefulness) of Logistic Information System were verified meaningfully. In this study, the efficiency of internal operation and organizational innovation were very important factor, to analyze the effects of Logistic Information System on performance. This study expect that Logistic Information System will achieve their Logistic Information System competitiveness through continuous quality measurement and improvement to increase the performance.

As an emerging e-retail model, private shopping malls are transforming the traditional retail systems. These malls are expanding in Europe and the United States and have recently arrived in Korea. This study investigates the relationships among the usefulness of SNS(Social Networking Sites), shopping values, and purchase intentions for fashion products in private shopping malls. The analysis was based on a survey of consumers, aged between 20 and 39, who recently purchased fashion products from a private shopping mall. Two hundred samples were used in the final analysis. The study employed descriptive statistics, Cronbach's alpha, confirmatory factor analysis, and structural equation modeling. The relationships among usefulness of SNS, shopping values, and purchase intentions was verified through structural equation modeling. More specifically, the usefulness of SNS significantly influenced the utilitarian shopping values as well as purchase intention of fashion products. Utilitarian shopping values, in turn, significantly influenced hedonic shopping values and purchase intention. Further, hedonic shopping values had a significant effect on purchase intention.

The purpose of this study is to investigate what influence the external variables of the RFID system for eco-friendly agricultural products such as reliability, safety, effectiveness and innovation have on ease and usefulness, perceived value and behavioral intention. An empirical analysis were conducted to the general consumers over the age of 20 years who live in Seoul and Gyeonggi areas having experience of buying eco-friendly agricultural products in department stores, supermarkets and eco-friendly agricultural product specialty stores from November 10 to November 23, 2012, A total of 350 copies of questionnaire were distributed for this research and, excluding partial ones that were too concentrated on one side or found missing values, a total of 305 copies(87.1%) were used as the final statistical analysis data. The result shows that such external variables of the RFID system for eco-friendly agricultural products as liability, safety, effectiveness and innovation are useful enough as a theoretical basis for later study on RFID systems for eco-friendly agricultural products. Also, it reveals that, since all the process from production to sale of agricultural products can be seen, the products are provided safely for consumers, are objectively and rapidly investigated when problems occur, induce a positive attitude with their historical information, and are supplied through systematic management such as consumers' rights to know and choose and recall of unfit products.
