This study was designed (1) to examine the results of previous qualitative research on clothing-wearing motives by quantitative approach, (2) to explore the concept of clothing utility, utility-reduction and discard, and (3) to investigate the impact of clothing-wearing motives on consumer attitudes and consuming-behaviors. Date were collected by questionnaire from 443 collegiate students between August and September of 2000, and 396 questionnaires were analyzed. 3 groups were identified on the basis of clothing-wearing motives and named by extroversion group, introversion group, and least clothing-congnizing group respectively. This supported the qualitative results in part, especially in the direction of motives. Clothing utility-reduction factors were identified as appearance demage, social-psychological damage, and abandonment-causing damage. The 3 groups were responded on utility-reduction differently, thus clothing-wearing motive variable was determined as useful in fashion marketing.

본 연구에서는 증권사 정보시스템의 아웃소싱 성과에 영향을 미치는 기업특성적 변인에 대해 파악하고자, 아웃소싱 수혜기업인 증권사의 조직 및 부문적 특성이 아웃소싱 정도의 매개효과를 통해 아웃소싱 성과(업무효용성, 업무능률성, 업무생산성, 예산감소율)에 어떠한 영향을 미치는지 실증적으로 검증하였다. 증권사의 조직적 특성(경쟁전략, 재무능력)이 아웃소싱 정도를 매개로 성과에 미치는 영향을 검증한 가설 1과 증권사의 부문적 특성(업무특수성, IT 자원, IT 역량)이 아웃소싱 정도를 매개로 성과에 미치는 영향을 검증한 가설 2를 실증분석한 결과, 경쟁전략, 재무능력, 업무특수성, IT 자원, IT 역량의 요인들이 아웃소싱 정도를 통해 업무효용성과 예산감소율에 영향을 주는 것을 확인할 수 있었다. 특히 재무능력, IT 역량 등이 업무효용성, 예산감소율과 같은 정보시스템 아웃소싱의 성과에 상대적으로 많은 영향력을 미치는 것으로 나타났으며, 정보시스템 아웃소싱 정도의 매개효과를 확인할 수 있었다.

Green roofs are being created in various purposes to use spaces. Most of them have been built with a goal as a resting place. However, the use of the green roofs needs to be raised. Otherwise, maintenance and administration of green roofs can be loosened. In addition, budget or cost involved can be wasteful. Therefore, this study makes a proposition if the satisfaction of green roofs is higher, the use of green roofs could be increased more. We are willing to analyze how beneficial the awareness can affect for the satisfaction with regard to green roofs. The findings can be helpful to provide a foundation data for raising the use of green roofs. We believe that the awareness benefits and satisfaction could be different depending on the facility's status on green roofs. Therefore, we classified green roofs of 11 department stores, in Seoul, into four types. Among them, we paid attention to five department stores that were able to represent each type. We analyzed the awareness benefits and satisfaction depending on the type of green roofs. We analyzed casual relationships between them using Structural Equation Modeling. We expect that the landscape architecture scholars will expand research on the various determinants in using green roof. een Roof; Type of Green Roof; Benefit Awareness; Satisfaction; Structural Equation Modeling;

We examine the methods to increase MBS values given parameters of default risks of individual mortgages and their correlation, and analyze the effects of these parameters on the efficiency of the methods. First, the values of MBS can be improved when they are comprised of low-correlation mortgages regardless of specific forms of investors' utility functions. Second, the values of MBS can also be raised even after their components mortgages are determined. More specifically, when investors' utilities are heterogeneous, CMO's of a less risky tranche and a riskier tranche are highly valued compared with pass-through securities of two identical tranches. When investors' utilities are homogeneous(risk averse), however, the latter meets the needs of investors better than the former does. Third, it can be shown that the efficiency of the methods in this paper is an increasing function of default risks of mortgage loans or of the correlation between them, and a decreasing function of the amount of the price fall of MBS when in default.

Recently, water conflicts are rapidly increasing and more serious. So, it needs to establish the reasonable water allocation rules and criteria. This study aims at performing inter-sectoral water allocation with a focus on economic effciency and social utility. To allocate water among the sectoral water uses, water shortage damage functions were estimated and then converged to the utility functions. Finally, each sectoral water uses are allocated by applying 'law equimarginal utility' to maximize social utility. Also weighting factor which reflects scale and characteristic of water demand in a region was estimated to perform the inter-regional water allocation. The water allocation rule was applied to the future water-deficit situation in Han-river basin. As a result, domestic water use was allocated more sufficient agricultural and industrial water use. Also, the water shortage occurs severely in the rural area like Gangwon-do because of its low urbanization and industrialization. This study suggests a alternative view of the economic water allocation which have difficulty under water supply mechanism in Korea.

네일(또는 락볼트)은 토사터널의 NATM 시공 시 보강재로 사용되어진다. 그러나, 네일의 적절한 설치방법이 아직까지 정립되지 않았다. 본 연구에서는 네일의 길이와 위치를 변화하여, 그 효용성을 연구하였다. 그 결과, 네일이 지반보강을 위하여 토사지반에 사용될 시 경제적인 길이는 터널직경의 0.5배이다. 보강의 효용성은 네일의 위치에 따라 터널라이닝 측벽의 하부, 중부, 상부의 순서이다.
