In this study, we observed air temperature to make clear that land coverage condition and stand form has a certain relationship to air temperature during the night in various green space. And with revolution analysis, we interpreted relationship of air temperature distribution in the green space, The way of analysis is this land coverage rate and air temperature, of number of tree volume of tree air temperature. With this experimental result, we can propose green plan, which is taking into consideration lower effect of air temperature. In this result, lower zone is formed in forest and water area, higher zone is formed in paved surface and barren ground. but this gap is a little. arbor+subarbor area, in the point of water area surrounded stand is formed relative lower air temperature. As a result to make up efficiency lower air temperature area, it is needed to make water area which has surrounded forest, and it is needed to make stand form lower air temperature 2~3 layer forest. In order of arbor, subarbor, shrub, the lower air temperature is more effect.

This study intends to propose the fundamentals of 'Ecovillage' design by researching into the cycle system of material of 'Crystalwaters' which is having been in charge of a leading role of GEN since 1996 (GEN was formed in 1996) as Ecovillage in Australia. First, to secure the water resources, we can store up rain and the water of valley, and dam. Second, we are able to use the natural filter apparatus, do tree-planting of roof to gain better quality of water. Third, it is to save the energy as supplying water. For it, we make the best of a gravity that is one of the cycle principle of water. Forth, to build a Dam can make a site of scenic beauty, do the role of recreation place and provide against emergencies (a fire, drought) as well as make a mild climate. Fifth, it can reduce the environment load because of sewage and garbage as making it compost. This is possible by treating biologically using composting apparatus of the dry or wet process. Sixth, it is to reduce the environmental pollution as to discharge seperating a recycable waste, an organic matter being able to make it compost. Finally, first of all, environmentally friendly inhabitant consciousness from lifestyle and production style plays an importent part for water cycle and the ecological cycle of waste and sewage.

Variety and individuality are characteristic of consumer in modern society. For the necessity of new designed men's formal suit is on the rise with advance of party culture and change of wedding style. In addition to growing numbers of Korean grooms are getting more interested in make themselves well-groomed on the wedding ceremony. The purpose of this study is to develop the men's formal suit pattern for right fit and better style for Korean grooms. In order to find out how to modify their fit, comparison among the existing patterns was necessary. In this study we proposed new patterns of men's formal suit, a morning coat, a tail coat, tuxedoes, director's suit, three-peaces suit, navy blazer. Considering the results of this study, developed patterns were altered to fit better and to smarter. They were well graded in waistline position, shoulder shape, back princess line shape. Also they were best to move around sleeve and bodice. And the developed patterns were altered to make armhole narrower to make bodice length shorter, to make bodice slimmer. The researcher's pattern's were made up into garments using wool 100%, silk 100%. According to verify the improvements and grade better in both appearance and comport, it will be to take the lead men's formal dress culture and expand the base of popular consume for men's formal wear.

Since the commencement of the fuel cell business in 2007, POSCO POWER has been the major supplier of the MCFC (Molten Carbonate Fuel Cell), which is the most commercialized stationary fuel cell system in the world. With its quite, yet active movement, more than 20MW MCFC systems have been installed and are operating in Korea. While trying to localize the components and set up a firm supply chain in Korea to provide more reliable and cost-competitive products to its customers, POSCO POWER is also devoting itself to developing new MCFC application products. One such product is a back-up power system, in which a back-up algorithm is embedded to the present system so that the product can work as a back-up generator in case of grid failure. The technology to enhance load following capability of a stack module is also being developed with the back-up algorithm. Another example is a building application, the goal being to make the present Sub-MW product suitable for urban area. For this, downsizing and modularization are the main R&D scope. The project for developing ship service fuel cell for APU application will launch soon as well. In the project, a system which can operate in marine environment, and reforming technology for liquid logistic fuel will be developed.

Theoretical IPMSM control technique is complicated, and reliability is low because of the changing parameters. Further, in case of general look-up table designing method which obtains torque characteristics (according to current and speed) or torque characteristics (according to magnetic flux through the entire control region), obtaining a precise result can be difficult and has the disadvantage taking too much time to establish a current look-up table. In this paper, the new auto maximum torque point tracking (MTPT) algorithm that automatically finds the optimum stator d - q axis electric current reference through the entire speed region is devised; consequently, it could establish a 3D look-up table with torque characteristics according to current and speed. In case of using the devised auto MTPT algorithm, the result value detailed was obtained in comparison with the generalized look-up design technique, and checked to reduce the current look-up table establishment time.

The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.

일반적으로 빌드업 다층 인쇄회로기판은 에칭, 도금등의 습식공정에 의해 제작이 이루어지므로 많은 장비와 많은 시간이 필요하게 된다. 이러한 습식공정은 양산에는 적합하지만 개발단계에서는 그리 적합하지 않은 방법이다. 본 연구에서는 스크린 인쇄기술을 도입하여 빌드업 다층 인쇄회로기판을 제작하여 보았다. 절연성 재료로는 광경화성수지 또는 열경화성수지를 사용하였으며 전도성 재료로는 전도성 페이스트를 사용하였다. 층간의 전기적 연결을 담당하는 비아와 회로를 형성하기 위해 스크린 인쇄공정을 통해 전도성 페이스트를 인쇄 하였다. 이러한 방법을 통해 제품의 개발 단계에서 기존의 빌드업 다층 인쇄회로기판 제작 공정과 비교하여 좀더 효율적인 방법을 제시하였다.

창업자의 기업가정신과 심리특성은 창업성공을 위한 매우 중요한 요인이다. 이와 같은 중요성을 인식하고, 본 연구는 창업자의 기업가정신과 심리특성이 창업성공에 미치는 영향관계를 고찰하였다. 이를 위하여 중소기업 진흥공단에서 설립 운영하는 청년창업사관학교에 입교한 청년창업자를 대상으로 조사한 설문지 122부를 실증 분석하였다. 분석 결과, 창업자의 진취성, 위험감수성, 자율성으로 구성된 기업가정신과 심리 특성인 내적 통제소재가 모두 창업성공에 긍정적인 영향을 미치는 것으로 나타났다. 이와 같은 연구결과에 따라, 다음과 같이 이론적 실무적 시사점을 제공하였다. 첫째, 창업성공 관점에서 기업가정신의 중요성을 인식하고, 창업을 구상하는 예비창업자들은 자신의 기업가정신을 가름해 보고 의사결정 하는 것이 바람직할 것이다. 둘째, 청년창업자들의 기업가정신을 고취시키기 위한 보다 효과적인 창업교육이 될 수 있도록 심혈을 기울여야 한다. 따라서 창업 보육기관들은 '기업가정신 훈련 프로그램'과 같은 교육과정을 개발해 나갈 필요가 있다. 셋째, 기업가정신이나 심리적 특성은 유 소아기 부터 형성되기 때문에 가정의 역할 또한 매우 중요함을 인식해야만 한다. 넷째, 창업자 스스로도 기업가정신을 강화시키기 위한 노력이 필요하다. 마지막으로, 창업자의 내적 통제소재를 강화시켜야 한다. 따라서 창업자 자신은 물론 창업 보육기관에서도 이에 대한 깊은 관심을 가져야만 한다.
