The human body composed of concave and convex curvatures, and the current 3D scanning technology which involves inherent measurement errors make it difficult to extract distinct curvature plot directly. In this study, a method of extracting the clear curvature plot and its application to the cycling pants design were proposed. We have developed the ergonomic pattern from the 3D human body reflecting cycling posture. For the ergonomic design line on the 3D human body, the 3D information on the lower part of four male bodies with flexed posture was analyzed. The 3D scan data of four subjects were obtained using Cyberware. As results, the iteration of the tessellated shell was executed 100 times to obtain optimized curvature plots of the muscles on the body surface, and the boundaries of the curvature plots were applied to the design lines. Maximum(Max-pattern) and mean curvature plots(Mean-pattern) were adopted in the design line of the cycling pants, and performance of those lines was compared with that of conventional princess line(Con-pattern). The average error of total area and length in the 2D pattern developed from the 3D flexed body surface in this study were very minimal($4.58cm^2$(0.19%) and 0.15mm(0.46%)), which was within the range of tolerable limits in clothing production. The pattern obtained from the flexed body reflecting cycling posture already included the contraction and extension of the cycling skin, so that the extra ease for movement and good fit was not need to be considered.

As you know, there are a lot of our own traditional folk village exist in Korea, our country. Most people just know is that Korean traditional village is just happen make it and just continuously keeping this times type. But this village is not just make it but made by serious scientific sources such as, rule of locating streets. There are three very important reasons why I research this topic for my research paper. The first important reason is that Korean traditional villages have the pattern of human moving line system in accordance with hyung-kug. Hangae village that located on inclined ground named baesanimsu has the longer human moving line than Hanbam village that located on level ground. The second important reason is that Korean traditional villages have the smaller human moving line of the length and the amplitude as long as going inside villages. But the unit of the amplitude is the larger. Hanae and Hanbam village is the same pattern. The third important reason is that Korean traditional villages have the smaller human moving line of the length and the amplitude as long as having the larger gradient. Hangae and hanbam village is the same pattern. And Hanbam village hast he bigger human moving line of the length, the amplitude and the unit of the amplitude. In conclusion, by these three important big reasons, Korean traditional village is built by scientific sources. And now we can say that our old generation was very unbelievable genius. By these reasons we have to make sure when we make another city town and farm village planning. The meaning of making sure is that a person who have responsibility for making city have to make plan by scientific sources. It has to be not only theoretical but also think about real human life. It also fit on our traditional.

Membrane structures, a kind of lightweight soft structural system, are used for spatial structures. The design procedure of membrane structures are needed to do shape finding, stress-deformation analysis and cutting pattern generation, because the material property has strong axial stiffness, but little bending stiffness. The problem of cooing pattern is highly varied in their size, curvature and material stiffness. So, the approximation inherent in cutting pattern generation methods is quite different. Therefore the ordinary computer software of structural analysis & design is not suitable for membrane structures. In this study, we develop the program for cooing pattern generation using geodesic line, and investigate the result of example's cooing pattern in detail.

On-line partial discharge(PD) monitoring system has been developed to monitor in operating large motor stator insulations. This system makes use of remote diagnosis techniques for the evaluation of PD activity in the control center of thermal power plant. This system can be remotely accessed via a modem to build database, analyze status and interpret the pattern of PD activity. A personnel computer is generally connected to ten motors to continuous measurement of the PD activity. The test data can be easily interpreted by a maintenance staff. For assessing the condition of stator winding in motors, this system ensures a reliable measurement and accurate estimation. Capacitive couplers used for on-line PD measurement have been 80pF. The maximum PD magnitude(Qmax), PD pattern and normalized quantity number(NQN) were performed by this system.

The purpose of this study was to develop a computer program to draft princess line onepiece dress pattern. To this study, the Turbo Pascal Compiler and the Pascal language were used. The procedures of the study were as follows: 1. A basic onepiece dress pattern was drafted by the hand operation. 2. The co-ordinate points were instituted for indication of relative position of all necessary points in drafting. Total sixty-nine co-ordinte points (front: thirty-five, back: thirt-four) were instituted. 3. The two subprograms for main program were developed to solve geometric problems and to draft straight lines and curved lines of the onepiece dress pattern. 4. The program was accomplished by putting indivisual body measurement 5. Grading fo five size was given.

Printing technology has begun to get into the spotlight in many ways due to the low cost effectiveness to existent semi-conductor process. It also has very useful application areas, not only paper printing but also patterning for LCD color tilter, Photovoltaic patterning, RFID antenna, OLED, and so on. In this study, an apparatus of gravure offset printing was developed for fine line width printing. The pattern was composed of $20{\mu}m$ size of continuous lines of which pitch size was $40{\mu}m$. The printed pattern shows that it is possible to make around $20{\mu}m$ line-width printing pattern. The roll-to-roll printing system for fine line-width printing based on primary experiment is presented. For testing of multi-layer printing, the system was designed to be capable of printing two different materials from each printing unit using gravure-offset printing method and have a function of alignment of two printed materials.

The effectiveness of tri layer resist (TLR) technique is compared with that of single layer resist (SLR) technique in order to make a 0.8um pattern with the linewidth deviation of 10 percents. SLR technique is not appropriate to shape the micro-pattern on oxide and aluminum steps because of the standing wave effect and the light scattering effect in shaping the resist pattern. On the contrary, the uniform line with a width of 0.8um on oxide and aluminum steps can be formed by TLR technique, reducting such effects. The planarization and the light absorption coefficient of the bottom layer resist in TLR are optimized by exposing it to ultra violet light after baking it for 30min at 230\ulcorner. An uniform line with a width of 0.8um on oxide step is defined with the light absorption coefficient of 0.85 whereas that on aluminum step is defined with 0.95.

Food away from home consumption pattern difference among 20 different social strata has been observed in order to make judgement how much food away from home expenditure should be included in the 2 tiered poverty line. It was found that it was reasonable to include food away from home expenditure in the minimum living cost. And as social class rose expenditure amount and percentage of consumption compared to total food expenditure increased and income elasticity and margial propensity decreased. Percentage of consumption compared to total expenditure increased up to middle class however from 14/20 and up strata decreased as social strata rose. For 4 members city wage earner family suggested monthly poverty line is 16, 977 and suggested monthly relative poverty line is 60, 651.

The only three elements such as RQD, N -value and Es were used as a quantitative standard for the design of supporr pattern determidetion on subway line 8th in Seoul. Because the support pattern that was obtained by these elements could not he determined on the basis of the quantitative of geology and the orientations and properties of discontinuity planes, there have been some problems in determining the economic support pattern and tunnel stability. Therefore, in an attempt to determine the stable and economic support pattern with more quantitative elements, more flerrible rock mass classification with geologic conditions was performed by using RMR at 1745 sections and Q-system at 374 sections within Seongnam block on subway line 8th. Then, rusults by these two methods were compared with standard support pattern of the subway line 8th. Moreover, relationships between geology, geologic structures and topography to rock mass grades were studied. According to the rusult of this study, it is judged that the standard support pattern designed with PD-4 or PS - 4 should have been subdivided into 4~6 support patterns. Some sections where geologic structures such as faults and joints are developed tend to have rock mass grades. And they also have low rock mass grades near valley. On thr other hand, they show intermediate grades at piedmont area and the greatest ones at high mountains.
