This design plan aims at the designing of the pharmacy counter as the space in which the two inter-related elements of the pharmacy, for example, the pharmacist and the customers, selling medicines and transmitting health informations, etc. keep in contact with each other. To create an ambience of intercommunication for health care and relaxation, it must be set up the basic concepts like Functionality, Flexibility, Transparence and Material-Change. As the design solutions : - first of all the long counter must be divided into the independent places with character and function. - in accordance with the basic concepts functionality and flexibility each small counter must represent a one's own form language that is determined according to a given function and also open and flexible to the change of the situation. - the various kinds of display module are introduced to bring out the functionality and the aestheticity simultaneously. - to make a contrasting image to each other various materials are arranged on and around the counters.

This paper describes an empirical equation which can be used to predict the engine condition of supersonic aircraft. The equation, which is derived from the trend analysis of JOAP data, represents the concentration of Fe particles in the engine oil. The result of the trend analysis shows that the concentration of Fe particles is a function of running time of engine oil. Meanwhile the slope of Fe concentration is a function of running time of engine. Threfore, the empirical equation was derived as $w=a(t_e).t_o+b$. However, the equation could not enough to diagnose the damaged part of engine quantitatively. To make up for the weak points of the equation, qualitative analysis was carried out. For that purpose wear debris were collected from the abnormal engine and analyzed by EDS to detect the damaged parts of engine.

This study was intended to find body pattern of middle aged women and make new experimental basic pattern for upper-half of the body for them. This experimental pattern on the idea of body pattern analysis was prepared. For experimental pattern, the prototype basic model was chosen with the best qualified D model from the four meaningful existing patterns. After several steps of correction experimental pattern was made. Comparing with basic D model, the new experimental pattern composed of additional bust girth by 1cm, wider back waist by 0.5cm than front waist and additional armhole by 0.5cm keeping the same size for back and front widths. Making a shoulder line up by 3cm the armhole became deeper accordingly and the room for girth has been transferred to length. Front neck girth became deeper downward but back neck girth risen a little bit. Side line of the bodice formed with inward slope taking from the waist line by 2cm. Instead of dart, modified side line slope was more practical by its function and appearance. Abdominal girth which is lower than waist girth by 8.5cm kept in same size with bust girth. Then abdominal girth became more comfortable. New experimental pattern with changes has been examined in function and appearance. In conclusion, the new experimental basic pattern for the middle-aged women has been proved more practical for both in bodice and sleeve than other existing ones in terms of function and appearance.

This paper is concerned with the set-up of the CE(Concurrent Engineering) model for the shortening of new product development. Recently, the situation of the new product development has been drastically changed. Customers require cheaper, better, stronger products in shorter product cycle time. To cope with this requirements from customers, engineers must accept new paradigm based on the CE and some special tools. This paper shows a tool, CE which is a good for shortening of new product development. So, CE was applied broadly in whole process of new product development and we could make it very successfully in quality, function, cost and developing time.

A strategy for the swing-up and stabilization control method for a two-links rotational pendulum according to states of each link of the rotational pendulum is proposed. The proposed controller consists of two modes of control such as divergence mode and stabilization mode. When the controller is in divergence mode, control input is generated using sinusoidal function, which is developed based on resonance period of the pendulum in linear region, to make the second link (pendulum) reach top position. After the controller finishes operation in divergence mode, stabilization control is initiated to keep the pendulum around the top position using pole placement control method. Experimental results are given to show the effectiveness of the proposed method.

This paper presents reconstruction of disparity in images. To achieve this, the algorithm was made up of two different procedures - one is extraction of boundaries for man-made structures and the other is matching of the structures. In the extraction of boundaries for man-made structures, we assume that man-made structures are composed of lines and the lines make up closed polygon. The convertional algorithms of the edges extraction may not perceive man-made structures and have problems that matching algorithms were too complex. This paper proposed sub-pixel boundaries extraction algorithm that fused split-and-merge and image improvement algorithms to overcome complexity. In matching procedure, feature-based algorithm that minimize the proposed cost function are used and the cost fuction considers movement of mid-points for left and right images to match structures. Because we could not obtain disparity of inner parts for the man-made structures, interpolation method was used. The experiment showed good results.

The first function of occlusion is mastication. Therefore the functional restoration of occlusal surface is very important. The restoration of occlusal surface is three method as wax bite technique, F.G.P. technique, cone technique. Many dental technician is using compound method. I am using compound method of wax bite technique and cone technique. I have knew common point on each teeth during I have waxing up wax pattern. So I studied on the design waxup technique for mandible molar occlusion. The results of the study were as follows; 1. The dam wax up method can restore axial contour of teeth very easy and make short working time of wax pattern. 2. The height of dam must be same with cusp of adjacent teeth. 3. Automatically the contour of tooth is appeared if the contour of dam is relationship with cuspid line of adjacent teeth. 4. The height of contour of buccal, lingual surface is formed natural curve to add fluid wax by gravitation. 5. The development groove of mandible first premolar is appeared V form. 6. The development groove of mandible second premolar is appeared Y form. 7, The development groove of mandible first molar is appeared M form. 8. The development groove of mandible second molar is W form. 9. The embrasure is formed to carve around contact point area as round convex. It affects to axial form of tooth. 10. The buccal, lingual groove of molar is formed parallel with direction of teeth arrangement.

Researches on after-sales quality have centered on home electric appliances, figuring out how factors influencing after-sales service quality are causally related to customer's behavioral intentions, via consumer satisfaction as an intermediary parameter In most cases of after-sales service in home electric appliances, upon customer's request, service agents make a visit to where the appliance is installed, and check the product and do repairs. However, in case of a small portable device such as a cell phone, which people carry around at all times, most of the times customers themselves show up at the after-sales center, and demand a check-up and repairs. The main difference here is that the after-sales services are provided when a product can no longer perform its basic function and customer dissatisfaction is already up. In this case, the basic function of a product corresponds to must-be factor according to Kano model. The goal of our research is to identify critical factors for effective and efficient after-sales service, and how to monitor them on a routine basis. In our research, the quality after-sales service consists of three dimensions, interactive quality, result quality, and physical environment quality. We set up variables for each dimension, which would measure from customer's perspective key determining factors in service delivery process. Instead of focusing on customer satisfaction aspect, we focused on how after-sales service factors contribute to addressing customer complaints. Additionally, our future research would aim to verify how customer's behavioral intentions are affected, as the resolution of consumer complaints becomes more successful when adjustment of relevant quality factors improves after-sales service quality.

본 연구는 장애인을 고려한 환경구축의 최종목표를 가지고 있는 일련의 연구흐름 중 가장 초기단계의 연구로써 장애인의 접근.이동성에 관하여 규정하고 있는 현행 국내법규를 분석하고 평가하는 것이다. 이를 위해 현행법에서 접근.이동성과 직접적 연관을 가지고 있는 실내구성요소­개구부, 복도 및 통로, 계단, 장애인용 승강기, 장애인용 에스컬레이터, 경사로-를 선정하여 연구코자하며, 객관적인 평가를 위해 각 실내구성요소별로 과거의 법규 및 2가지 관련 기준안과 비교.분석하였다.그 결과, 현행법은 장애인을 위한 편의시설 설치 의무조항을 추가하고 대상 시설을 확대하는 등 환경개선의 의지를 보임으로써 장애인의 사회참여를 유도하고자 하였다. 그러나 각 구성요소의 세부기준들이 극히 최소의 치수로 규정되어 있고 장애를 보완시켜 줄 기타 디자인 고려사항들이 언급되어 있지 않다. 또한 장애유형별 특성이 충분히 고려되지 않아 장애인들이 실질적으로 실내환경에 접근.이동하는데 무리가 따를 수 있을 것으로 보인다. 따라서 향후에는 장애인의 의견이 폭넓게 수렴된 기준을 설정하여 질적인 향상을 도모해야 할 것이며 선진복지국가들의 장애인관련 법률 및 규범을 분석.연구함으로써 우리실정에 맞게 접목시키는 노력도 잇따라야 할 것이다.
