This study examines the relative efficiency of 34 local public medical centers in Korea. In order to concretely grasp the causes of inefficiency and suggest improvement solutions, the desirable set point was established based on the actual value which needs to be improved. As a result of analysis, we determined that output must be increased while input is held constant in order to improve effectiveness through the actual value and set point. Efficiency cannot be achieved if input is augmented solely to increase output. Also, to increase output, the medical centers need to improve their quality without increasing any input for customer visits and hospitalizations. Further, in order to strategically promote effectiveness and efficiency of local public medical centers, these medical centers must focus on input resource and patient interchange through the mutual cooperation with local private hospitals and university medical centers.

The purpose of this experimental study is to investigate the shear behavior of high-strength concrete deep beam and to grasp the conservatism of ACI Building Code. Experimental results on 12 deep beams under two equal symmetrically placed point loads are reported. Main variables are vertical and horizontal web reinforcement and shear span-to-overall depth ratio. Test results indicated that web reinforcement dose not affect on formation of inclined cracks but shear span-to-overall depth ratio affect on inclined shear cracks and ultimate shear strength. Addition of vertical web reinforcement improves ultimate shear strength of H.S.C. deep beams that shear span-to-overall depth ratio is 1.0. Considerable increase in ultimate shear strength of H.S.C. deep beams with increasing horizontal web reinforcement that shear span-to-overall depth ratio is 0.5. Especially with increasing concrete strength($f_{ck}$) the ACI code is conservative in estamating the ultimate shear strength of deep beams.

The samples for testing have been collected from Kangdong-myon, Nongso-myon, Beomseo-my on, and Cheongryang-myon in Ulju-Ku, Ulsan-city from July 1994 to March 1995 in order to grasp status of trace metals contained in some rice, soybean and soils, and to provide references in establishing their standard 96 collected samples(48 for cereals and 48 for soils) have been tested to measure levels of Hg, Pb, Cd, Cu, and Zn through methods of trace metal containing analysis and heavy metal analysis. moisture content was also analyzed. And at the same time 0.1N-HCl soluble heavy metal content of soil was measured. The average Hg containing level of samples is 0.006 ppm for cereal and 0.062 ppm for soil, Pb is 0.302 ppm for cereal and 1.137 ppm for soil, Cd is 0.012 ppm for cereal and 0.027 ppm for soil, Cu is 2.01 ppm for cereal and 0.885 ppm for soil, and Zn is 7.853 ppm for cereal and 2.366 ppm for soil.

In this paper, we have implemented mobile based smart greenhouse system that can grasp and control the situation for greenhouse from distance. Using existing web based greenhouse system is controlled in real time, but it has a drawback used in limited place. To solve this problem, we have emphasized usability of smart greenhouse system by using mobile device. By using mobile devices (smartphones - the Android based) software we have to raise the comfort and productivity for grasping and controling the situation for greenhouse from distance.

The purpose of this study is to grasp the meaning of retro-fashion, to research the formative feature characteristic and aesthetic values. Retro-fashion is one of the expression of spatiotemporal-eclecticism, The formative of modern Retro-fashion are as follows: First, Retro-fashion based on spatiotemporal-eclecticism have been come from 40s, 50s, 60s, 70s, 80s style of time, and the asia, africa, middle east, latin America in region. Second, the design inspiration and technique is used more primitive crafts and decoration like handcrafted material, handmade ornaments as dyeing and embroidery of bohemian, jacqwuard pattern, oriental beads, applique, new hippie touch, patchwork, smocking, primitive button, woods, ethnic motives. Third, modern Retro-fashion is reflection of human feelings as nostalgia from the past, it supplies the sense of fashion creativity and new ideas.

This study puroses to grasp the change of dwelling space by the change of family organization according to the change of population in the rural area of suburbs of city that suppose to receive the influence of the city. The method of this study is to collect data about form village houses in monographs and reference books and study change factor of houses. To the selected village we will interview local inhabitants and officials and observe and survey the farm village houses by visiting houses. Through the research results we will know the change of population organization that cause the change of room utilization. We know that village pepole have living articles in dwelling space. We expect that the farm village houses will become city houses only in the dwelling space. So the suburban farm houses must be planned as in relation with the city.

The aim of the study was to grasp the current trends and to predict the future trends of space composition characteristics by analyzing floorplans drawn by housewives as their ideal apartments. The content analysis method was used for this study. This research used data from a competition held in 1993 by a housing construction company. Among 3,102 floorplans collected 12,232 were selected by Proportional Stratified Sampling Method. The major findings are as follows; 1) Some major features were interpreted as current trends; respondents wanted new rooms that could accomodate various functions separated the private spaces from public trends; they wanted to expand the verandah both visually and actually put importance on the number of bathrooms and have the space for outdoor living and leisure activities.

The sublime as one of categories of aesthetics has given a great influence over art. Particularly, painters of Color-field Abstract, which can be considered as the art of the sublime, have tried to sublimate their art to the level of spirituality through expression of sublimity. The purpose of this study is to grasp distinctive peculiarities of sublimity expressed by Rothko, a Color-field painter, in his architectural work, Rothko Chapel, and manifested by Feldman through his musical piece, also titled Rothko Chapel, respectively.In conclusion, it is found that sublimity was expressed in both works through ‘immobile procession’ corresponding to ‘dualism’ of the sublime as Kant defined. More specifically, it is clarified that such immobility was expressed through the attributes of the sublime as suggested by Burke, and they implied dualism.

The purpose of this study is to grasp musical expression in the Monastery of La Tourette, an architectural work produced by an architect, Le Corbusier and a musician, Iannis Xenakis based on a musical piece, Metastasis. The results of the study on musical expression in the Monastery of La Tourette, which was done through analysis of correlation in expression between architecture and music, and spatial characteristics of this monastery, are as follows: First, in modern architecture and music, the expression of the space-time continuum concept is emphasized. Second, the architectural characteristics in this monastery that constitute musical expression are the Modular, confliction and fluidity in composition, plastic (acoustic) shape and symbolic shape. Third, these architectural characteristics are found to be expressed as counterpoint, alteration, temporality, acoustics and canon of music.

Dust explosions are occurring in a variety of industries. A dust explosion caused by a specific energy generates huge amount of energy in the ignition and releases decomposition gas. Damages can be increased since this released decomposition gas can cause second and subsequent explosions. In this study, the goal was to obtain practical information on what could affect the explosion by comparing the characteristics of two kinds of dusts with completely different chemical properties. Three kinds of dusts were measured and evaluated for explosion pressure, dust explosion index, explosion limit and minimum ignition energy. It is possible to grasp the characteristics of each dust and use it as useful accident prevention data in the production of raw material powder.
