  • 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.

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.

  • Entrepreneurship of a founder and psychological characteristics are very important factors for the start-up success. To understand the importance like this, this study investigated effect relationships of the entrepreneurship and psychological characteristics on the start-up success. For this, 122 copies of the questionnaire were empirically analyzed for the youth entrepreneurs who entered the youth founder academy which is founded and managed by the Small and Medium Business Corporation. According to results of analysis, both the entrepreneurship consisting of proactivenss, risk taking and autonomy, and the internal locus of control, the psychological characteristics were found to have positive effects on the start-up success. Therefore, this study suggested theoretical and practical implications, as below, according to the results. Firstly, we must be aware of the importance of the entrepreneurship from the perspective of a successful establishment, and, prospective entrepreneurs, who are planning to the start-up, have to judge their entrepreneurship and, only then, make a decision. Secondly, we have to put our best efforts into developing more effective education on start-up, which deals with improving youth founder's entrepreneurship. Therefore, education institutions for start-up are needed in order to develop educational programs such as "Entrepreneurship Training Programs". Thirdly, we must recognize that the role of family is important because most entrepreneurship and psychological characteristics are formed in a person's childhood. Forth, the entrepreneur, themselves, must realize that they has to make an effort to improve their entrepreneurship. Lastly, youth founder's internal locus of control has to be enhanced. Thus, greater attention is required from both the entrepreneur themselves, and educational institutions for start-up.
