The characteristics of agricultural water rights in multi-purpose dams in Korea was examined. The river system with multi-purpose dams can be divided into national river system and WRC(Water Resources Corporation) river system according to ownership of dam use rights. While the national river system have permitted water rights, the WRC river system have vest water rights and contract water rights. The two river systems have different characteristics of agricultural water rights, and therefore the water right of two system need to be unified. It is also known that water release from multi-purpose dams against water demand does not satisfy agricultural water rights.

This paper deals with the legibility of Korean characters(Hangeul) on car number licence plates. We focus of the height-width ratio as key factor affecting the legibility in experimental procedures. The results of experiments are; i) For vertica characters, the vest height-width ratio was 1:1 for 3 throuth 5 stroke characters, and 4:5 for 6 and 7 stroke characters. ii) For horizontal characters, the best height-width ratio was 1:1 for 3 through 5 stroke charcters, and 5:4 for 6 and 7 stoke characters.

Airway clearance technique are used to aid in mucus clearance in a variety of disease states. In this review I discuss airway physiology including airway mucus, action of airways, and airway resistance and review the literature and theory regarding forced expiratory technique, active cycle of breathing technique, and autogenic drainage. Also, I look at the appropriate device such as positive expiratory pressure mask(PEP mask), Flutter, and HFCWO(Vest system) which can be applied in the field of respiratory physical therapy. This study is provided as the basic resource regarding the application method of respiratory physical therapy.

It is difficult to secure public lots in the downtown area, school lots can be made the best use of important source to increase the area of green land in the city. The tree-planting campaign for schools has been in force since 1999 by the city of Seoul and at present; it is currently established as the plan of school parks. Thereupon, the purpose of this study is to present some ways to revitalize elementary schools to be used as vest pocket parks through the research of elementary schools, which are subject to the plan of school parks in Seoul. The results of this study are as below : The subjects to revitalize school parks as vest pocket parks are as follows. First, the land has to be utilized for security of space. Second, in addition to the front and back gate, another passage to the park has to be set up for easy access. Third, the fence has to be formed as a hedge used outside the park. Fourth, selecting plants, species of trees suitable for the landscape of school and taking into consideration the aspect of ecology. Finally, it is urgent to enact socially and economically proper standard of law by the new standards of area for school landscape considering not only the building law and regulations of general landscape, but also specific characteristics of school landscape.

본 논문에서는 해양인명구조 시스템에서 송신부인 구명조끼의 무선 송신기로부터 송신된 조난 신호를 효과적으로 수신하기위한 426MHz 대역 패널 형태의 평판형 마이크로스트립 안테나를 설계 및 제작하였다. 제작이 용이하고, 가벼우며, 적은 제작비용이 장점인 마이크로스트립(Microstrip) 안테나 구조를 이용하였으며, 협대역, 저이득, 큰 사이즈 특성을 극복하기 위하여 IDMA(Identical Dual Patch Microstrip Antenna with Air-Gap) 구조를 응용하여 설계하였다. 안테나는 유전율 4.3, 두께 1.6mm를 갖는 FR4를 사용하여 제작하였으며, 측정된 안테나의 대역폭은 $S_{11}=-10dB$ 이하에서 28.7MHz(약 6.6%), 이득은 426MHz에서 3.04dBi로 우수한 특성을 얻었다. 또한, 상용 송수신모듈을 사용한 거리측정 실험을 통하여 5km 이상의 송수신거리의 안정적인 통신성능을 확인하였다. 본 논문에서 제안한 안테나는 향후 UHF 대역 통신시스템의 기지국분야에 다양하게 응용될 수 있을 것이다.

This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

In this thesis which takes fashion advertising that functions a marketing communication as an objective, I try to bear witness to the signifying system of garments though analyzing with semiotic methodology the signifying procedure on the base of the structural concept of Ferdinand de Saussure and the advertisement semiotic theory of Roland Barthes, to make clear their signifying structure and it meaning by understanding the characteristics of contemporary society and its cognitive system. Each sign of fashion advertising transfers the brand image through syntagmatic signification which contains the mythology of goods. Mannish style is encoded as tailored jacket, white shirt, H-silhouette and pants, non-color or being color, and it is presented as a clothing sign of casual wear for career women. Feminine style is encoded as X-silhouette, soutien collar suit style, various colors, and other details with womanly image, and it is presented as a clothing sign for maid or young wife 20\`s or 30\`s. Formal style is encoded as jacket vest, inner wear(blouse), two and three piece dress by pants or skirt and one-piece dress, and it is used in every age and class. Casual style is similar to formal style, but differs only in textile code. Clothing sign for housewives in middle age is encoded as H-silhouette of formal style, long jacket and pants and brown, being and grey colors. Contemporary popular phenomena in the signification of fashion advertising, and its temporal ideology reflected are as follows; According to the context of fashion advertising in the middle of 1990\`s, its fashion is that first, military look applied from the designs of various sort of military uniform and vest look and pant style applied from dandy-style imitated from man\`s wear are popuar. This mean that it reflects the change of point of view on woman\`s role in society today. That is, due to the equality between man and woman, it mirrors the ideology of feminism, and then, describes beautifully professional woman with carrer. Second, because that individualism is underlied for the change of consumer\`s consciousness, standardized popularity is disappeared, and in accordance with the mixture of various trends and personalities proposed every season, layered look that emphasizes individualism, easiness and naturalness is popular.
