The purpose of this thesis is presenting desirable design of uniform which could reflect high school girls' demands with the researches on their consciousness of fashion and actual state of uniforms. Methods to accomplish this research include first, examinationson characteristics of high school girls and their consciousness of fashion with relevant articles, second, interviews with designers from major domestic uniform brands - ELITE, IVY, SMART - and third, analysis on related internet sites. Practical researches are followed by design analysis and proposal of improvement on high school girls' uniform, accompanied by collection of photographs from field studies, major uniform brands' shops and uniform related internet sites. Korean high school girls in the digital era are able to express themselves in each different fashion with own individuality, preference or intention, as they are particularly interested in clothes or their appearances. Their consciousness of fashion became visible in a shape of negative attitude and dissatisfaction with uniforms due to its out-of-date design, lack of features and inconvenience in action. Besides more than half of high school girls already experienced reforming it for better looks. As a result of current analysis on references of uniform designs, various levels of refinement were noticed even in uniform of similar details, design, fabric textile and color due to differences on size & length of jacket collar, dart, cutting line, size of details, decorative line, easiness in fit, length of clothes, and etc. To provide students of more refined and desired designs which reflect their demands, current uniforms are to begin acquiring delicate changes with present vogue and feature such as size of details, silhouette, cutting line, decorative line and etc. In addition newly designed uniforms are to present desirable design with image of refinement and neat as they actively comprehend students' needs within its symbolic, functional, economic and aesthetic characteristics by nature.

It is very difficult to control the expansion of reed at a wetland ecological park due to their aggressive reproduction capability. Therefore, proper topography and wetland hydrology should be provided before the construction of a wetland ecological park. Appropriate measures should be taken at the initial stages to prevent reed expansion. Field experiments were conducted at the newly constructed wetland ecological park for 15 months to develop methods to control the reproduction and expansion of Phragmites communis. A complete shading method had the best effect on the prevention of reed reoccurrence among other methods. Complete removal of the rhizomes controlled the reed growth to a greater extent than cutting the aboveground shoots. Water-level manipulation was also better than a half-shading method for the prevention of reed reproduction. These results indicated that soil properties and edge effects can influence the reed growth. Cutting only the aboveground shoots facilitates the growth of reed. These results suggest that reed control should be implemented repeatedly and an alteration in the wetland topography and hydrology may be more effective in the long term. Combination of treatments such as water-level management with shading should be considered to control the growth of reed. Adoptive management for created or restored ecosystem might be considered for accomplishment of its original purpose.

A Study was made to improve soil and water temperature and mechanized farming for a wetted paddy under the influence of artesian groundwater located at Samcheon-Dong, Chuncheon City, Kangweon Province. Half perforated PVC drainage pipes were installed in the test paddy to observe temperature change of water and soil. The temperature of the water in the paddy and soil itself raised significantly after the installation of the half perforated PVC pipes. A subsequent improvement of growth and yield of rice on the paddy was achieved. Harvesting operation was also improved with firm ground condition so that cutting and threshing could be done simultaneously within the paddy plot. Following results were obtained from the study. 1.Temperature of the water in a paddy under the influence of artesian groundwater was not changed notably although air temperature was fluctuated during the crop period. Soil temperature was mostly affected by the artesian groundwater. However, the half perforated PVC pipe drainage system made it possible to raise temperature of water and soil remarkably up to the level of optimum farming. 2.Total precipitation was 534.Omm during the crop period of the paddy for 118 days from May 26 to September 20 in 1992. Due to heavy rainfalls of 105.6mm and 109.8mm occurred on August 7 and August 27.1992, respectively, the rate of the artesian groundwater increased to 35 litter per minute with two to three days of time lag. 3.Average rate of the artesian groundwater was 28 litter per minute from the one year of observation. The rate varied by 0.7 to 1.3 times of average during the observation period. Peak rate of the artesian groundwater decreased to 14.5 litter per minute when daily precipitation maintained at the amount of 20 to 30mm for a long time period. Contrarily, it showed a tendency to increase to 35 to 40 litter per minute when heavier precipitation of 50 to l00mm occurred in a short period of three to five days. 4.Growth and yield of Yemyung variety of rice planted on the paddy that was facilitated with a drainage system with half perforated PVC pipes were confirmed at a normal level, while paddy without this perporated drainage system showed abnormal growth with low yield.

The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.

Building integrated photovoltaic(BIPV) system operates as a multi-functional building construction material. They not only produce electricity, but also are building integral components such as facade, roof, window and shading device. As PV modules function like building envelope in BIPV, combined thermal and PV performance should be simultaneously evaluated. This study is to establish basic Information for designing effective BIPV by discovering relations between temperature and generation capability through experiment when the PV module is used as roof material for houses. To do so, we established 3kW full scale mock-up model with real size house and attached an PV array by cutting in half. This is to assess temperature influence depending on whether there is a ventilation on the rear side of PV module or not.

A model experiment of purse seine by the circulating water tank was carried out on the changes of net shape and the tension of purseline under operation in two layer current. In the circular tank, the two layer current was made by cutting off the current of upper layer and producing the bottom current by the equipment shown in Fig. 1. The model experiment of purse sein was made on a reduced scale 1 :400, and the experiment was carried out according to the Tauti's model law. When the bottom current of O. 5 knot flows to lower part of three-eighths of net, following results are derived. The depth of sinkerline reached only about 80% of that of no current set. The horizontal shift of sinker line caused by the bottom current is maximized in tight set. The enclosed area by the floatIine immediately after the completion of set net is 61. 5% in tight set, 50. 0 % in loose set and 54. 1 % in lateral set of those in the case of no current. In the first half period of pursing, the tension of the purseline is enhenced by the bottom current and the pattern of increasing is irregular in the tension curves.

The NdFeB magnet can be classified into the sintered magnet and bonded magnet. The former has superior magnet characteristics but the degree of freedom in shape is highly restricted, whereas the latter has a high degree of freedom, but its magnet characteristics are inferior to the former. When a NdFeB magnet is used at the elevated temperature, part of Nd must be replaced with a high priced Dy to increase its coercive force. For these reasons, a Dy free and high performance NdFeB bonded magnet is desired strongly. The author successfully developed a Dy free NdFeB anisotropic bonded magnet based on discovery of new phenomena called as d-HDDR reaction and its mass production process such as a thermally balanced hydrogen reaction furnace, micro capsuled powder, compression molding / injection molding under magnetic field, magnetic die and so on. Applied to DC brush seat motor for automotive use, the motor has become 50% small in size and weight. The commercialization of a half sized motor for automotive use has been realized up to the market share of 30%. At present, its commercialization is extending to various types of motors such as power tool, ABS motor, wiper motor, window motor, electric bike power motor, and compressor motor. It is expected that the applications will be increasingly enlarged to EV motor, wind generator, EPS motor, washing machine, and glass cutting machine. This innovative technology has realized Dy free high performance magnet and mudt make big contribution to not only rare element strategies but also energy conservation.

Employers are realizing that workplaces have an immense impact on productivity. And, because people typically represent about 90% of a company's costs, even a slight improvement in productivity hits the bottom-line in a very big way. The focus is shifting away from saving money by reducing space needs or cutting energy requirements, and moving toward making the workplace friendlier and healthier. What is a healthy workplace, exactly? The answer should be clear by now. Mountains of research have expounded on this very topic, and then news outlets cover the latest discoveres ad infinitum. The problem is, research is rather dense, while the news isn't comprehensive. Office managers trying to improve workplace wellness want neither a 55-page report nor a half dozen articles to convince their landlord that their space can do better. Recognizing this gap, Harvard researchers have released a concise-yet-complete list of healthy building features. Here, we're sharing these nine features with a few insights of our own on the value of being healthy and productive. Find out: ${\bullet}$ What makes a healthy building and why is it so important ${\bullet}$ How to improve the health of your own office ${\bullet}$ What happens for your people and your bottom line when you make health a priority.
