The purpose of this study is to analyze consumers' purchase behavior for the counterfeits of fashion luxury brands. The research method of the study used a naturalistic approach. The first participant observation was carried out in the internet sites in order to collect the data on the purchase behavior for counterfeits; and the second participant observation was applied in the Dongdaemun shopping mall, Namdaemun shopping mall and Itaewon shopping mall; finally 6 informants were selected and then an interview was held with them. The results of the study are as follows; 1. The reasons for the first purchase of counterfeits are variously shown according to life stages, and the repetitive purchase behavior is influenced by the degree of satisfaction for the first purchase. The information collection for counterfeits is widely made through various media, and especially the information collection is active and positive in the case of planned purchase but it is passive and negative in the case of unplanned purchase. 2. The most important criteria in purchasing counterfeits is the degree of similarity with luxury brands and other criteria include price, design, utility etc. The majority of purchase items is not clothing but miscellaneous goods which are more similar in terms of design and quality. The purchase of counterfeits is made by impulse purchase but the purchase of luxury brands is made by planned purchase. 3. The rationalization mechanism for the purchase of counterfeits is observed in all informants, which is a sort of defence mechanism for avoiding a guilty conscience to buy illegal goods.

This study held a questionnaire for men in their 60s or above to analyze the market research of slacks, understand the characteristics of their lower body types, and provide the basic data for the slacks pattern-making fitting the body types of senior citizens. The findings are as follows. According to the results of a questionnaire, elderly men preferred order-made slacks for better fitness, but they favored ready-made owing to the matter of prices. In particular, the girth of waist was the most considered when purchasing. However, as most customers tended to repair slacks length and the waist part, their unsatisfaction with sizes was rather high. In body measurements, elderly men had higher variable coefficients or more individual differences in the items of thickness and angles than in those of height, length, and girth. Factor analysis revealed 5 front and 6 side factors. According to the results of front-side somatotype analysis, pimento-flat, trapezoid-flat, and bent-flat types require narrower pattern designs in down-upper width than the middle-aged class. In addition, pimento-protruded hip and straight-jar types need to be designed in the same amount as in the middle-aged class. Based on the questionnaire results, down-upper length as 1cm above real dimensions was analyzed to have superior sense of wearing.

Vibration problem of deckhouse structure in a container vessel was investigated through the analysis and measurement. The natural frequency of deckhouse structure was found to be resonant with main engine 4th order excitations in the operating range, major sources of which were main engine inertial moment and axial thrust of the propulsion shafting system. To investigate and solve the problem, exciter test was performed to identify the vibration chracteristics of the ship structure and mechanical balancer was installed to compensate the 4th order inertial moment. Measurement results under the conditions with and without balancer operating were compared and analyzed to confirm the balancer effect. Good coincidence was found between the measurement and analysis results, which made it possible to predict the vibration problem in the earlier design stage.

The aim of the paper is to use optimization and advanced numerical computation of a sail fiber-reinforced composite model to increase the performance of a yacht under wind action. Designing a composite-shell system against the wind is a very complex problem, which only in the last two decades has been approached by advanced modeling, optimization and computer fluid dynamics (CFDs) based methods. A sail is a tensile structure hoisted on the rig of a yacht, inflated by wind pressure. Our objective is the multiple criteria optimization of a sail, the engine of a yacht, in order to obtain the maximum thrust force for a given load distribution. We will compute the best possible yarn thickness orientation and distribution in order to minimize the total fiber volume with some displacement constraints and in order to leave the most uniform stress distribution over the whole structure. In this paper our attention will be focused on computer simulation, modeling and optimization of a sail-shape mathematical model in different regatta and wind conditions, with the purpose of improving maneuverability and speed made good.

In order to get the information needed for the preservation and application of Korean traditional dyeing techniques to modern textiles products, the present study analyzed the color and color differences of dyed goods according to the contents of fabrics and the traditional techniques of dyeing the Buddhist priests' robes. A spectrophotometer was used to measure the differences in achromatic color according to dyeing techniques, dyestuff, kinds of dyed fabrics, and after-treatment methods. Through experiments based on the traditional dyeing techniques used by Korean Buddhist priests, a total of 144 pieces of dyed fabrics were made and all the colors of those 144 pieces were analyzed. Among three dyeing techniques tested; (1) dyeing with a dye-bath made of ink stick that was ground down with water, (2) dyeing with a dye-bath made by shaking a bag containing ink powder in water, and (3) dyeing with a dye-bath made by rubbing a boiled ink stick on a fabric, dyeing with a dye-bath made of ink stick that was ground down with water was shown to be the best technique in terms of coloring. For fabrics, ramie was the best of all three techniques in terms of making achromatic color. Starching and rubbing was the most effective after-treatment method used on both fabrics dyed with a grounded ink stick and on fabrics dyed by rubbing a boiled ink stick on them. As a whole, yangyeonmook, made from minerals' soot, is better than songyeonmook, which is made by burning old pine trees or yooyeonmook, which is made by burning oils from seeds. Therefore, yangyeonmook could help to preserve and utilize the traditional dyeing techniques of Korea in a practical way in modern life.

The tunnel type spillways is under construction to increasing water reservoir capacity in Dae-am dam. The tunnel outlet was planned to be made after installing slope stabilization system on natural slope there. Generally, the tunnel outlet is made perpendicularly to the slope, but in this case, it had to be made obliquely to the slope for not interrupting flow of river. Because of excavation in condition of natural slope caused to deflecting earth pressure, the outlet couldn't be made. So, artificial ground made with concrete that it was constructed in the outside of tunnel for producing the arching effect which enables to make a outlet. We were planned tunnel excavation was carried out after artificial ground made. Artificial ground made by poor mix concrete of which it was planned that the thickness was at least 3.0m height from outside of tunnel lining and 30cm of height per pouring. Spreading and compaction was planned utilized weight of 15 ton roller machine. In order to access of working truck, slope of artificial ground was designed 1:1.0 and applied 2% slope in upper pert of it for easily drainage of water. In addition to, upper pert of artificial ground was covered with soil, because of impaction of rock fall from upper slope was made minimum. The tunnel excavation of the artificial ground was designed application with special blasting method that it was Super Wedge and control blasting utilized with pre-percussion hole.

Many similar class components are stored in object-storage but the object-storage has needed the retrieval function of correct component for reuse. Accordingly this paper designed the class component retrieval viewer of the object-storage by using the improved spreading activation strategy. Object-storage has made up of information of inheritance relation, superclass, subclass, and we defined the queries about each class function. Also we specified connectionist relaxation of the each class and query, finally we gained retrieval result which showed highest activation value order of class component information including the query function.
