  • The purpose of this study is to find important personal characteristics that affect search process and outcome, and to formulate causal models about searching behavior, by examining the channels and the magnitude of the factors identified. The study was designed to conduct a quasi-experiment with 67 student subjects. A total of 29 elements concerned with aptitude, personality, formal education, effectiveness of online training, search process, and search outcome are measured and reduced to 9 variables. 12 hypotheses were tested statistically and path analysis was done to investigate causal relationship among variables. Finally 5 models were formulated.

  • It has been known that test collections play an important role for researches in information retrieval. A variety of test collections have been created in foreign countries, and have been heavily used by researchers. Although research interests in Hangul information retrieval have been rapidly grown up in Korea these days, lack of Hangul test collec tions makes it difficult to develop retrieval techniques for Hangul texts. This study describes the development of the KRIST test collection. The KRIST test collection consists of 13.515 bibliographic records. 30 queries and a list of relevant documents to the queries.

  • The operation and management of a plant require proper accounting for the constraints coming from reliability requirements as well as from budget and resource considerations. Most of the mathematical methods to decide the inspection time interval for plant maintenance by reliability theory are too complicated to be solved. Moreover, the mathematical and theoretical models are not usually cases in the practical applications. In order to overcome these problems, we propose a new the decision-making method of optimal inspection interval to minimize the maintenance cost by reliability theory and genetic algorithm (GA). The most merit of the proposed method is to decide the inspection interval for a plant machine of which failure rate $\lambda$(t) conforms to any probability distribution. Therefore, this method is more practical. The efficiency of the proposed method is verified by comparing the results obtained by GA-based method with the inspection model haying regular time interval.

  • To utilize abundant potatoes effectively, it was studied on alcohol fermentation strains which were isolated and identified. Fifteen yeast strains with high alcohol fermentation ability were isolated from rotted potatoes. Among them, two isolated strains, 5-3A and 10-4B showing the highest alcohol fermentation ability were identified as Zygosaccharomyces fermentati based on the morphological and physiological characteristics. Their optimum conditions for the alcohol fermentation in 25% glucose were pH 3.0, 30$^{\circ}C$ and 150 rpm of shaking speed, respectively.

  • This study is intended for international cooperation in the field of LED were analyzed. The results, LED wide coverage areas, and a promising future is expected to grow fast enough to occupancy for a major national technology is a competitive situation. Chip Scale Package, including our country, such as LED manufacturing technology that might be competitive in parts, but new technologies such as renal substrate R&D and technology development still active preemption is not the situation. Renal substrate, particularly, large-diameter sapphire, large size/large LED manufacturers, such as a promising area for future research and development support will be needed. To do this, previous research in this area and the U.S., Japan cooperation in such studies also will need to expand. Bibliometrics way through this study, analytical techniques and analytical tools used in the integrated analysis of the usefulness and necessity of the system development were found.

  • Human capital theory and social capital theory provide a framework for analyzing economic well-being. The purpose of this study was to investigate the effects of human capital and social capital on the economic well-being of the elderly. The data from the 1st wave of KLoSA (Korean Longitudinal Study of Aging) were used (n=3,426). The major findings were as follows: First, human capital and social capital are both resources that can contribute to increasing the economic well-being of the elderly. Second, the effects of human capital on the economic well-being of the elderly were relatively higher than the effects of social capital. Third, the relative contributions of human capital and social capital to increasing economic well-being varied by sex, age, and region. Based on the empirical results, the implications for social investment in human capital and social capital were provided.

  • The purpose of this study was to analyze the education policies for work-family balance in Korea. Data were collected from homepages of elementary schools(n=196). The major analysis was performed through the following 4 subjects, parent-teacher association, after-school programs, holidays on every alternate Saturday, arbitrary no school days. Based on the results, the policy implications on social investment policies were discussed : To promote work-family balance, family-friendly culture in workplaces as well as schools should be established that develop childcare system for working parents. The linkages between educational system and work system will contribute to parents' rights in Korea.

  • The purpose of this study was to investigate the determinants of policy demand for elderly care in aged Korea. The data from the first wave of KLoSA (Korean Longitudinal Study of Ageing) aged over 45 were used (n=10,165). The major findings were as follows: First, human capital, social capital, and socioeconomic variables influenced on the expected demand for elderly care by government, controlling the expectations of future life and society. Second, the effects of determninants on the expected demand for elderly care by government varied by the level of human capital, social capital, and socioeconomic variables, including ADL and IADL, familial support by children, public transfers, and age.

  • The purpose of this study was to examine the effects of human capital and social capital, including employment status, education, income, social supports, and social participations, on the health status of the elderly aged over 50, after controlling for various demographic variables. Data were from the 6th wave of the Korean Labor and Income Panel Study(n=3,459). The major findings of this study were as follows: First, human capital and social capital were both resources that can contribute to improving the health status of the elderly aged over 50. Second, the effects of human capital and social capital on the health status of the elderly differed in the three subsamples defined by employment status. Based on the empirical results, policy implications were provided.

  • Shanghanlun is a medical text published by the Jiaozhengyishuju in 1065 A.D. during the Northern Song dynasty. The first edition featured larger characters but in 1088, a version with smaller characters was published with reduced price. This study compared various versions of Shanghanlun to clarify its system. Especially the alteration in the Chinese version by Jhao Kai Mei was comparatively analysed by the shape of letters and specific marks. Also, information on the various publications in Japan is included in this study, which we believe will be the logical outline for comprehensive understanding on the propagation and progression of Shanghanlun in East Asian region.
