The purpose of this study is to investigate the somatotype variation & satisfaction with the fit of ready-to-wear for overweight women. For this study, questionnaires were administered to 154 overweight women in Andong & Daegu areas. Employing a sample of 116 data were analyzed by using F-test. And 10 overweight women's brands were analyzed for sizing system of women's ready-to-wear. The results were as follows: In the satisfaction with the somatotype variation of overweight women, length items increased and girth items decreased with aging. At neck, bust, waist, hip and sleeve circumferences, satisfaction with the fit of ready-to-wear decreased with aging. Correlation for somatotype variation & satisfaction with the fit of ready-to-wear was significantly positive. And main sizing system of overweight women' s ready-to-wear brands was size 99 & 105 cm(bust)-90 cm (waist)-110 cm(hip), and its sizing intervals was almost existed in range of 5 cm-7 cm. There were various sizing systems in overweight women's ready-to-wear brands, and it raised a problem of consumer's dissatisfaction.

This study is the design research for the practical use of Casual Hanbok. The conclusion of basic research for Casual Hanbok design reads as follows. Today's college women are fairly positive to the practical use of Casual Hanbok. Especially, they are strongly interested in the new design and have the active intention to wear it on actually. The concrete design of every parts of Casual Hanbok which is wanted by college women is as follows. Firstly, college women like well matched two-piece dress style in colors. And they want to decide the coloration independently than to follow the traditional coloration passively. Secondly, according to the design of jacket, sometimes they like the presence of a collar, a collar strip, a gore etc. and at other times they like absence of them. Thirdly, the side line of jacket they like and the seam line of sleeve they like is smoothly curved one and the adjusting means they like is a fancy button. Fourthly, the length of jacket they like reaches to their waist and the width of an armhole they like must be convenient for moving of arm. Fifthly, one out of two college women likes mixed spinning fabrics as material for jacket, skirt, pants. In the other hand, one out of five college women likes cotton. Sixthly, the skirt style they like is A ­line one having from two to four gathers on the waist and the length of skirt they like reaches to their ankle or calf of the leg.

Concrete wedge anchor is one of structural components to transfer load of an object attached to a primary structure. Recently, as retrofitting concrete structure is becoming a main issue, mechanical capacity of the anchor should be secured enough. In spite of the structural safety of Cast-in-place anchor, Post-installed anchor is more widely used with ease of placement or change of construction method. However, the post-installed anchors domestically produced have excessive coefficient of variation over 15% of ultimate tensile strength, which yields deteriorated quality in tensile strength. In this research, tensile strength test of anchors, which have improved sleeve and header and produced by a domestic company, was conducted for two variables, concrete strength and effective embedment depth. As a result, enough coefficients of variations were secured in all specimens. Also, in comparison to foreign products, the domestic ones have equal or higher performance.

A tele-operated robot should be used to maintain and inspect nuclear power plants to reduce the radiation exposure to the human operators. During an overhaul of the nuclear power plants in Korea, a ROV(Remotely Operated Vehicle) may enter a cold-leg connected to the reactor to examine the state of the thermal sleeve and it's position in the safety injection nozzle. To measure the positions of the thermal sleeve or scratches from the video images captured during the examination, the camera parameters should be identified. However, the focal length of the CCD camera could be increased to a close up of the target and the aspect ratio and the center of the image could also be varied with capturing devices. So, it is desired to self-calibrated the intrinsic parameters of the camera and capturing device with the video images captured during the examination. In the video image of the safety injection nozzle, two or more circular grooves around the nozzle are shown as ellipse contours. In this paper, we propose a camera self-calibration method using a single image containing two circular grooves which are the greatest circles of the cylindrical nozzle whose radius and distance are known.

This study aims to develop a spring/fall motorcycle jacket for quick service transporter. Depending on the results of the previous research, this study produced the tested jacket which was improved in material, pattern, and design. For the tested jacket, 100% polyester fabric excellent in strength, durability and abrasion-resistance was selected as a major material, and Cordura was used as a partial material to improve the strength and abrasion-resistance of the sleeve side lines, elbow and shoulder areas. The retro-reflection material was applied partially in order to improve visibility of the jacket in the night or in a dark place. A total of 7 pockets were composed in the jacket for the sufficient storage spaces. The functional design elements such as the 2-way zipper and the placket at the center front, the action pleats at the upper part of back armholes, the pit-zip at armpit were applied. In addition, the sleeve pattern was bent with the shape of elbow curvature in time of driving and the back length of the jacket was lengthened 4cm. As a result of the appearance assessment, there was a significant difference from the existing jacket in all items but chest size, shoulder width, cuffs circumference, and jacket hemline circumference. In motion adaptability and field activity appropriateness assessments, the assessment grade for all items was found to be commonly higher than that of the existing jacket, and thus, the tested jacket was assessed to be suitable for a motorcycle jacket design for the quick service transporters.

본 논문에서는 압축공기를 작동매체로 한 저압용 vortex tube에 대한 에너지분리 과정을 상세히 연구하였다. 먼저 vortex tube에서 에너지 분리되어 나오는 온공기와 냉공기의 온도변화에 대하여 실험하였고, vortex tube의 안쪽표면의 최대벽면온도 변화와 vortex tube내의 온도분포를 통하여 vortex tube내 유동장에서의 정체점의 위치에 대한 유용한 정보를 얻게되었다. 이를 바탕으로 vortex tube의 최적 길이와 throttle의 형상, sleeve에 따른 에너지분리과정 등을 실험을 통하여 알아보았다. 또한 본 연구에서는 디젤기관의 배기에 적용하기 위한 외통을 사용하였다. 이때 vortex tube에서 나오는 은공기가 180$^{\circ}$돌아 나오면서 vortex tube의 바깥쪽 벽면을 가열하게 된다. 이러한 기하학적 형상을 통하여 에너지분리효과가 증대됨으로 인하여 디젤기관의 배기가스에 적용 시 고온유동의 온도를 높이고자함에 본 연구의 목적을 두고자한다.

This study conducted a questionnaire survey of family restaurant employees in Seoul on their satisfaction and preference in working uniforms, and analysed the result to suggest adequate designs to serve the purposes of uniforms. The result is as follows - First, many pointed out a need to improve generally showing a low satisfaction with varying degrees according to sexes and ages. More women complained about colors, designs, materials and sizes than men did, and young employees in their twenties wanted better designs, colors and sizes in the order while those in their thirties and forties were dissatisfied mostly with materials. The need fur the improvement was focused on function and designs, and as for uniform materials, perspiration absorbency had the highest level of dissatisfaction. Second, about 40% of the respondents said the skirt width, pants length, and sleeve width were trio small or too big, therefore it is vital to improve uniform sizes. Third, the employees on duty felt uncomfortable mostly when they sat, and the neck and armhole parts were the most uncomfortable. The most easily tainted parts were in the order of the collar, front hem, and sleeve seam for upper garments, and the hip, bottom hem, and pleats for lower ones. Therefore it is required to develop functional uniforms considering the body features and momentum. Fourth, the most preferred material was that guaranteed easy movement and good air-permeability, and colors were in the order of white, beige and black for upper garments, and black, beige and blue for lower ones. And plain, natural and stripped patterns were preferred by both men and women. As seen so far, restaurant employees were mostly dissatisfied with the design, movement, and function of their uniforms demanding functional ones made of better and comfortable material. Uniform designs were suggested based on the analysis of the demonstrative rese.
