The purpose of this study is to systematize various clothing production methods that domestic fashion brands are utilizing to produce fashion products, and to propose effective clothing production methods according to the characteristics. The research methods are contents analysis method of the literatures, articles, reports, and interviewing method of the practitioners who are in charge of the production of fashion. First, the clothing production methods of the domestic fashion brands are categorized as follows. It is divided into a fashion brand management method and a promotion company entrustment method based on who carries out the clothing production and management. The fashion brand management method is subdivided into the 'rental-production', 'CMT', and 'self-production' methods. All three methods are performed at domestic and global sourcing, but the CMT method is more utilized at the global sourcing. The promotion company entrustment method is subdivided into the 'full consignment production method', the 'CMT method involving promotion company', and 'direct buying method by promotion company'. All methods are performed at domestic and global sourcing. Second, the results of reviewing effective clothing production methods, according to characteristics are as follows. If fashion brands control the production and management, they use all three fashion brand management methods. The fashion brands use the promotion company entrustment method when they wants to offer special products, or the number of items is large, or the production management is difficult, or the manpower and equipment size is reduced. The domestic sourcing is utilized by fashion brands and promotion companies when production management is required for high quality apparel production, in case of trendy and complex designs, spot production, and in small quantity production. The global sourcing is utilized by fashion brands and promotion companies when it comes to lowering the production cost, fashion brands preferred the mass production of apparel with design that can be pre-planned.

Marine production strings are continuously affected by unstable internal fluid during operation. In this paper, the structural governing equation for marine production string self-induced vibration is constructed. A finite element analysis model is established based on Euler-Bernoulli theory and solved by the Newmark method. Furthermore, based on reliability theory, a self-design procedure is developed to determine the operability envelope for marine production string self-induced vibration. Case studies show: the response frequency of the production strings is consistent with the excitation frequency under harmonic fluctuation and mainly determined by the first-order natural frequency under stochastic fluctuation. The operability envelope for marine production string self-induced vibration is a near symmetrical trapezium. With the increasing of natural gas output, the permissible fluctuation coefficient dramatically decreases. A reasonable centralizer spacing, increasing top tension, and controlling natural gas output are of great significance to the risk control in marine production string operation.

본 연구는 보철치료의 최종 목적인 결손치아 및 그 주위 조직의 정상적 기능의 회복과 유지를 위한 전치부 교의치의 반 자정(ridge lap)형 가공치의 체계적인 제작 방법을 연구하였다. 가공치가 갖추어야 할 설계 기준를 제도화 하였고, 치과의사의 소견으로 염증, 치주질환, 음식물 잔류 및 자정작용의 효과가 기존의 제작 방법보다 더 우수한 결과를 얻었다. 본 논문에서 제시하는 가공치 제작방법은 임상에 적용해도 무방하다고 판단된다.

DPRK have been encountered serious food problems in recent years, because of lack of availabilility of supplies, unfavorable weather conditions and above all lack of production incentives for farmers. Self-management is one of the method of increasing production incentives for farmers. For the well established self-management program, DPRK have to distribute farmland to farmers, not property rights but utilization rights. However farming situations are different, the distribution methods will be different according to the farming situations.

Lightweight concrete is known for its advantage of reducing the self-weight of the structures, reducing the areas of sectional members as well as making the construction convenient. Thus the construction cost can be saved when applied. to . structures such as long-span bridge and high rise buildings. However, the lightweight concrete requires specific design mix method that is quite different from the typical concrete, since using the typical mix method would give rise the material segregation as well as lower the strength by the reduced weight of the aggregate. In order to avoid such problems, it is recommended to apply the design mix method of high performance self-compacting concrete for the lightweight concrete. Therefore, this study introduces a production of self-compacting concrete, PF-modified and improved version of Nan-Su's design mix method of self-compacting concrete. Through a series of test mixes conducted during the study, the quality of the concrete at its fresh condition has been evaluated per the 2nd class rating standards of self-compacting concrete published by JSCE, especially focused in its fluidity, segregation resistance ability, and filling ability.

This study aims to set up Energy self-sufficiency urban planning system responding climate change by reducing fossil energy consumption and carbon emission, and to suggest effective application method. This study has 3 levels. First, it defines energy self-sufficient city responding climate change theoretically. Second, it set up planning system of Energy Self-sufficient city responding climate change. Third, ANP method was applied to introduce priority of application according to relative importance of planning section. As ANP method has to construct network to show interrelation among elements, 1st questionnaire survey was carried out to figure out interrelation. 2nd questionnaire survey introduced to judge relative importance of planning aspects and sections. In conclusion, this study shows interrelation among planning sections. By considering the relative importance, Energy environment and Energy consumption was derived as important planning aspects, and Architecture, Landuse, and Production of renewable energy was estimated as s important planning elements.

Nowadays, various sides such as political, economical, technical and social sides of the companies' environment are changed rapidly. Such changes could provide a risk on one hand and a good chance on the other hand to the companies. Only one that has quick self-adaption can survive such kinds of challenges. Thus, from now on, profitable survival of a company depends on how fast they can adapt for the changes. Therefore it is introduced here the production method of a new concept for solving many problems which exist in the present production and manufacture.

The control algorithm of a new type self-bearing step motor is presented. The motor actuator is used for both motor and bearing functionality without any redundant coil windings or redundant electromagnets. The self$.$bearing step motor layout and its control method are described. A linearized farce-current-displacement relationship is derived. As the result of the unbalance response approach, the constant torque production is possible fur the supply current regulation algorithm. And even if the bearing functionality is added in the motor functionality, no additional current for bearing functionality is possible, and this leads to minimize the net power loss. Also, the unbalance response shows the independent bearing force and motor torque.

According to increase of the factory-automation(FA) in the field of production, the importance of the autonomous guided vehicle's(AGV) role has also increased. This paper is about an active and effective controller which can flexibly prepare for changeable circumstances. For this study, research about an behavior-based system evolving by itself is also being considered. In this Paper, we constructed an active and effective AGV fuzzy controller to be able to carry out self-organization. To construct it, we tuned suboptimally membership function using a genetic algorithm(GA) and improved the control efficiency by self-correction and the generation of control rules.
