The purposes of this study were to identify money altitudes of college students and to examine both socio-economic characteristics and clothing purchase behaviors by different money attitudes. For this study, guestionnaires completed by 2-year and 4-year college students (n=426) were analyzed by factor analysis, cluster analysis, X²- test, and ANOVA. The results of this study were as follows: First, the money attitudes were composed of five factors and they were categorized by three clusters: cluster of considering the money as a tool for future safety, a way of approval and filling up emotions, and inclination toward stinginess and distrust. Second, the factors which were associated with money attitudes were academic level, education level of parents, household income, students' own income, and the economic level of their households. Third, in each type of attitudes, the clothing purchase behavior had four steps of decision making: problem recognition, information search, evaluation of alternatives, and the purchase. There were significant differences in the clothing purchase behavior among the money attitude styles.

Reliability demonstration tests with zero-failure acceptance criterion are most commonly used in the field of reliability application since they require fewer test samples and less test time compared to other test methods that guarantee the same reliability with a given confidence level. For products with lognormal lifetime distribution, an economic zero-failure test plan is developed that minimizes the total cost related to perform a life test to guarantee a specified reliability of a product with a given confidence level. A numerical example is provided to illustrate the use of the proposed test plan.

WTO was established in 1995 and as many as 36 new members joined WTO until December 2017. Thus it would be interesting to see if new members have committed higher or lower levels of market opening compared to the original members. In this regard, a sophisticated scoring scheme is needed to quantify market opening commitments. After proper econometric model is established for the original members, same model can be applied to the new members for comparison. It was found that new members committed a much higher level of commitment than the original members. In addition, it was also found that transition economies committed higher levels than the non-transition economies. More interesting finding is that among the new members, the larger the economies or the larger the trading volume are, the closer was the level of commitment to the predicted level. Then the question is whether this difference was due to benign neglect by the new members or due to malign select by the original members.

Sustainability assessments tend to integrate ecological, social, and economic concerns. Sustainability assessment could be considered the highest rung in the assessment ladder. Broad strategies that seek to integrate individual SEA(Strategic Environmental Assessment) could be subjected to a sustainability assessment. Sustainability assessment could incorporate global and transboundary effects and priorities into SEA and project-level EIA(Environmental Impact Assessment). SEA could provide an environmental context and direction for project-level EIA. Procedural and substantive EIA requirements can be addressed through tiering such as sustainability assessment, SEA, project-level EIA. In Korea, PERS(Prior Environmental Review System) that has been utilized to evaluate administrative plans related with various kinds of development projects should be evolved not only to incorporate environmental impacts into early stage decision-making, but also to implicate sustainability assessments that include social equity and economic efficiency. Integration of SEA and sustainability assessment can be initiated through the application of DPSIR (Driving Force - Pressure - State - Impact - Response ) framework that was developed by European Environmental Agency.

Growth of the Korean economy has been sluggish, and this situation is more pronounced in the service sector. We argue that capital misallocation, especially in the service sector, could contribute to this slowdown. Utilizing firm and sectoral level data, first we assess the rising dispersion of the marginal revenue product of capital (MRPK) driven by the service sector. This could represent a widening misallocation of capital. Furthermore, a panel regression shows that within-sector misallocations at the sectoral level are closely correlated with the lower growth rate of sectoral real value added. Again, this is mainly observed in the service sector, but not in the manufacturing sector. Misallocations of other resources, labor and the intermediate inputs do not stand out.

Economic injury level and control thresholds for the management of beet army worm, Spodoptera exigua (Lepidoptera: Noctuidae) were evaluated on chinese cabbage of two different planting time. Two inoculation times were tested for each planting and the number of inoculated larva was 10, 20, 40, 80, respectively. Damages of leaves by first inoculation were 63.2% after eight days planting on 80 larva inoculation plot. By the second inoculation, those were below 50% after 20 days planting on the end of September. The linear relationships between population density and yield reduction were as following; Y = -10.62x + 867.9 ($R^2\;=\;0.643$) for 5 days and Y=-6.432x + 1074 ($R^2\;=\;0.720$) for 20 days. Based on these results the economic injury level was 5.4 larva for five days and 9.0 larva for 20 days per 20 chinese cabbage. The control thresholds calculated by 80% level of economic injury level were 4.3 and 7.2 larva, respectively.

Health has been seen as a resource necessary for both maintaining oneself and for living in a society pursuing high quality of life. Therefore, the medicare provision takes place of one of the most significant indexes for evaluating the regional welfare level. The purpose of this study is to investigate the locational characteristics of medicare service facilities. For the purpose, the distribution patterns of the medicare resources are analyzed both at the regional and local scales. The medicare resources are concentrated at the Metropolitan Seoul area in the regional scale, and they are also concentrated at the economic core areas in the local scale. Especially, higher level medicare resources, such as the general hospitals and medical specialists, show more concentration at the economic core areas than lower level services. This means that access to opportunities to receive higher level medicare is poorer in a more socially disadvantaged area. Since medicare service facilities are invested and operated by both private and public sectors, whose locational mechanisms are deferent, we analyzed the distribution patterns. Most medicare facilities are invested and managed by private sector in Korea, which is operated by market mechanism. This is related with the fact that the medicare facilities are concentrated at the economic core areas. The proportion of private sector is higher in the Metropolitan Seoul area, and thus this region shows stronger spatial disparity of medicare provision. In general, the medicare service facilities are located in the hierarchical structure, and thus the services levels and facility scales are differentiated by the hierarchy. We examined the hierarchical structure in the medicare service facilities in Korea. The referral medicare system has been applied with the assumption of the three level hierarchical structures in Korea. However, we could not find any distinct hierarchical structure in the scales of the medical service facilities.

This study examined the economic structure of male one-person households, and investigated how it differed by male's age and marital status. Specifically household incomes, expenditure patterns, assets, debts, and other demographic variables were compared by age and marital status. From the 2000 National Survey of Household Income and Expenditure conducted by Korea National Statistical Office(KNSO), 1,389 male one-person households were selected. The findings of this study were as follows: First, the economic status of male one-person households was unstable. They were more likely to depend on labor incomes and transfer incomes, and had less property incomes and total assets. Their average propensity to consumption was higher than that of general households. Second, the economic structure of male one-person households showed large differ+useholders in age 50s allocated $48\%$ of household expenditure to the non- consumption categories, especially child or (ex)spouse support payments. The economic status of householders in age 60s and over was inferior to those of the other groups. Third, there were considerable differences in the economic status of male householders who had different marital status. Divorced and separated males had higher incomes and expenditures, but assigned large portion of their incomes to the non-consumption categories. Widowers' level of economic living, such as incomes, expenditures, and assets, was the worst among male one-person households.
