This study presents methodology and tools for remote measurement of the orientation of the rock parting surfaces. Two close circuit video camera capture the pictures of a rock excavation surface while a laser beam scans the surface. Positions of the laser beams in the two digital images are recognized by image processing. Using the stereoscopic concept, three dimensional coordinations of the rock surface and the orientation of the rock parting planes are calculated. Point, cross and line type laser beams are tested for better image processing results and measurement accuracy of the coordinates. According to a simple accuracy test, cross beam show better results than the point beam. However, line beam show more promising results for the measurement of the rock parting surfaces.

Despite the fact that chogakpos are part of our wonderful Kyubang(the women's quarters in the Chosun Dynasty) culture with their own unique beauty and artistic values, there has been no scientific and objective proof of their aesthetic values. Once they are proved for their beauty through scientific analysis, they will be recognized worldwide along with our unique culture. The methodology included a review of related literature and theses along with magazines, periodicals, and Internet books. The analysis of lines parting, the dimensions of chogakpos were carried out over 108 pieces introduced in Old Pojagis by Heo Dong-hwa. As for line parting, the dimensions of chogakpos were measured to see if the golden and Geumgang ratio could be applied and to discover their unique partition ratio. As a result, there was the presence of the golden ratio applied to them with the golden curves from golden triangles and rectangles also found therein. The Yeoijumunbo confirmed that there was the golden ratio between the radius of a circle and a side of a regular decagon inscribed in the circle. The common line ratio among the squares, isosceles triangles, wanes, and overlapping rectangles was around 1:1.31, which means that there was a unique line ratio in the traditional chogakpos. Furthermore, the ratio of 1:1.31 was close to the Geumgang ratio commonly used in the traditional buildings of Korea.

During the design of dies and molds, the cavity of the object is obtained by subtracting it from a surrounding rectangular block. This box is subsequently split into two halves by the parting surface. Similar problems also occur in some RP processes such as LOM, SGC, SLS and 3DP where the machine produces a block inside which the prototype is buried. Determining the orientation of the object inside the box and the corresponding parting surface taking appropriate constraints into account have been addressed by several researchers. However, given the parting surface, the problem of splitting the box development of a software package called OptiLOM (now a module of an RP software Magics 8.0), the authors realized non-triviality of this problem since the loop can spread over as many as 5 faces of the box. In this paper, the authors have tried to bring out the importance of this problem and have presented their algorithm to solve it.

In this paper, an efficient algorithm is proposed to find parting lines(PL) and generate parting surfaces(PS) for an injection mold design. We used a Face-Edge Graph which can be made by B-rep information of solid model. The graph is useful for finding the peripheral-loop edges for PL and the inner-loop edges for hole-patch. The PS can be generated automatically by selecting pre-defined direction lines. We can create a core and cavity molds by trimming the raw stock block with the PS and the upper/lower faces of a product model. We implemented proposed method with Unigraphics API functions and C language, and tesed on Unigraphics V15.

Injection compression molding (ICM) is an advantageous processing method for producing thin and large polymeric parts in a robust manner. In the current study, we employed the ICM process for an energy-related application, i.e., thin and large polymeric battery case. A mold for manufacturing the battery case was fabricated using injection molding. The filling behavior of molten polymer in the mold cavity was investigated experimentally. To provide an in-depth understanding of the ICM process, ICM and normal injection molding processes were compared numerically. It was found that the ICM had a relatively low filling pressure, which resulted in reduced shrinkage and warpage of the final products. Effect of the parting line gap on the ICM characteristics, such as filling pressure, clamping force, filling time, volumetric shrinkage, and warpage, was analyzed via numerical simulation. The smaller gap in the ICM parting line led to the better dimensional stability in the finished product. The ICM sample using a 0.1 mm gap showed a 76% reduction in the dimensional deflection compared with the normal injection molded part.

The adapted scope of the Opening-covering-axis of Three-yin-three-yang can summary two parts. the first, former treatise of Gyeng-Lak emphasized the line structure by point and line but now we can understand expansible structure as not only line but also space of structure by the space structure of six-meeting. So the application of Gyeng-Lak can be various by extensive analysis of the Hand-three-yin-three-yang in Sky(Yang) including the Foot-three-yin-three-yang in Ground (Vin), even if the original text has limited examples. The second, former additional explanations of Hwangjenegyeng Sanghanlon by doctors can be profoundly analysis about the pathology and cure process of Three-yin-three-yang of human body. It has base on the metaphorically symbolized theory of Three-yin-three-yang. This is the Saeng-jang-shu-chang of So-yin, Tae-yang, Yang-myeng, So-yang. Tae-yin, Guel-yin in order. Also the circulation of Opening-covering-axis of Three-yin-three-yang has order in Tae-yang (Opening), Yang-myeng (Covering), So-yang (Axis), Tae-yin (Opening), Guel-yin (Covering), So-yin(Axis).

In this article, the authors studied the characteristics of Costumes used in the Chung Won(中原) District through Shymui(沈衣) and Dopo(道袍) which was widely used as Confucian traditional costume. It was concluded that the costumes in the Chung Won district are very similar to those of Seoul area. The reason for the similarity was due, in addition to nearness to Seoul, to the mixed cultural background during Sam Kuk(三國) dynasty and due to the influence of many returned scholars who are accustomed to the life of ruling class while in Government position in Seoul during Lee Dynasty(李朝). The traditional characteristics of Dopo in Chung Won District also is, unlike other area, very similar to Seoul. Dopo in An Dong(安東) and Kang Nung(江陵) Districts have no parting line in the back while that of Seoul area had parting line. The material used for the Dopo in An Dong area was mainly Sambae and in Seoul Moshi or Myung Ju was the major material for the normal occasion and Sambae was used for the Dopo for funerals.

In this study, a computer program was developed which generates automatically a drawing of the forging design in axisymmetric hot-forging of steel. The program designs a forging envelope from a machined part geometry according to forging design rules: parting line, draft angles, fillet and corner radii, minimum web and rib thicknesses. For the purpose of verification, the program was applied to a machined part from a factory. It was found that the generate forging design agreed well with the actual one used in the factory.

For the most part of machine design, assembly drawing isaffected byits inserted parts. When a part is inserted in assembly, alreadyd stablished parting line is modified for reasonable representation. for example, break or trim fuction between the lines gives more recognizable drqwing. Most of parts is composed of such that point, line, arc, circle and block. If the part is composed of block, it is very difficult to operate because its attribution is unknown before exploding, but, It is very easy to operate except block. In this paper, it is required that basic feature recognition rules are caused by knowledge-based. This system which shows a good modify tool using AutoCAD system and ADS (Autocad Development System).

The purpose of this study is to propose the design of the patient's clothes for a disabled child between 4 and 6. For this, in this study, I would present the following design plan which includes 3 upper garments, 2 trousers and a one-piece dress. In case of the damage on head and neck, a neck line should be deep and wide thereby providing ease to the clothes. To facilitate injection and dressing/undressing, there should be parting from neck to cuff which can be fixed by snap or button. By rolling up sleeves with strings inside the cuffs and fixating plaster cast with snap button outside the cuffs. In case of body cast with plaster cast around body part, front adjusting part should be wider and the width should be adjusted with strings. In case of hip spica cast which covers waist, I separated front part and rear part, fixated them with snap buttons, gave more width to front adjusting part with strings to adjust width, which constitute one-piece dress. In case of shoulder spica cast, the other shoulder which is not covered with plaster cast should be exposed, and to prevent clothes' coming down, strings with snap button or velcro should be attached over a shoulder so that the length of the strings can be adjusted. In case of applying plaster cast or aid to the whole part of a leg, one part of trousers should be shorter so as to expose the injured part and there should be a parting with strings or velcros on the side for easy dressing/undressing. When plaster cast or splint is short, The strings are meant to adjust length of trousers. The partings are located 2 cm from side lines toward the center.
