It is thought that a composition of trousers is related to fabrics with single breadth. Therefore, trousers are designed with pattern using this fabrics with single breadth. However, in the old pattern of trousers, the breadth of 33cm-35cm was not considered in designing patterns. In this context, deciding which pattern design is better is not easy as there are a variety of estimation methods. So in this study, standardization of drafting is pursued by an objective pattern design. For this, a base angle of the trouser closely relating to a form and function was measured and using the height and the base angle, a trouser pattern design was tried. For a measurement of the base angle, 5 subject were selected. They are 25-29 year-old male graduates with fine physical standard. The base angle was measured with symphysis pubis point as a standard when subjects sat with their legs crossed, when they stood with their legs open (not forced artificially) and when they laid down with their legs open. The distance between a knee inside joint and knees was measured three times and the resultant value was used for the pattern design. For a design of trousers, the height was applied and the base angle was fixed. As a pattern drawing, using the height, a base angle and circumference of the hip, a trouser was designed. The production method for the pattern design is as follow: (1) The length formula, is height + $\frac{height}{2}$ (2) The hip girth formula is $\frac{hipgirth}{2}$ - $\frac{hipgirth}{20}$(3) A crotch angle is fixed at $72^{\circ}$. (4) The ratio of outer leg length to leg width is 5 : 8. (5) The component ratio of the upper outer leg length to the pant length is 5 : 8. (6) The ratio of the division point of front right inner leg length and left inner width to upper outer leg length is 5 : 8.

This work is mainly done by too many manual operations in the aircraft structure design process resulting in heavy workload, low efficiency and quality, non-standardized processes and procedures. A top-down associated design method employing the template parametric technology is proposed here in order to improve the quality of design and efficiency of aircraft wing structure at the preliminary design stage. The appropriate parametric tool is chosen and the rapid design system of knowledge-driven aircraft wing structure is developed. First, a skeleton model of aircraft wing structure is rapidly built up through the template encapsulated design knowledge. Associated design is then introduced to realize the association between the typical structural part and skeleton model. Finally, the related elements are referenced from skeleton model, and a typical structural part reflecting an automatic response for design changes of the upstream skeleton model is quickly constructed within the template. The rapid design system proposed and developed in this paper is able to formalize the design standardization of aircraft wing structure and thus the rapid generation of different aircraft wing structure programs and achieve the structural design knowledge reuse as well.

Postmodern designers freely used historical motifs as symbolic expressions or ornamentations. Historical references often became a key to express their ideal against modern standardization. Among the historical references, Art Deco style was frequently appreciated by postmodern furniture designers from the 1960s throughout postmodern era. This study is Intended to explore the way of incorporating Art Deco in postmodern furniture design. Rational Italian designers in Anti-design Movement began to adapt historical motifs and Pop, and this spread out throughout to other Postmodern designers. The research explored how Art Deco and postmodern design are related and what the examples of Art Deco revival in the postmodern era we. In this sense the research mainly covered from the exhibition catalogs from the 1960s to 1990s. As a result of stylistic, symbolic, methodological analysis, Art Deco revival in postmodern era was an essential method to express anti-modern characteristics of postmodernism. In postmodern design, Art Deco was one of historical styles that surpass the limitation o( modernism, at the same time decorative style that express the postmodern ideal.

According to the design method for constructing the Korean Men's Jo-go-ri(the traditional Korean jacket)collar, there are differences in form after its completion. In the construction design of the midsection of the gusset as in that of the basic pattern Jo-go-ri, not only was the positioning of the two sides of the collar not smooth, but also, when the collar strip(Dongjung) was attached, there would be an imbalance on one side or the other so that it was difficult to achieve symmetry. Therefore in this project, by applying the pattern design of the gusset midsection to that of the collar midsection, not only did attaching the collar(Kit) and the collar strip create a visual effect by equalizing the lengths of the two sides, but the construction was also easy. This method of construction introduces the three-dimensional aspect of the human form in its conic, spherical and cylindrical aspects, so that, through schematizing the scientific character of Korea's clothing, its appropriateness is verified. As a matter of fact, since there is no standardization of pattern whether for educational use or for mass-produced clothing, so that even the patterns used in computer-assisted design are executed according to the designer's personal skill, the reality is that after completion of construction the quality has not been uniform. For this schematization, inverse calculation of measurements pertaining to the calculation formula and of teaching materials has been referenced. In particular, the partial regulation of the calculation formula pertaining to the basic pattern construction, the method of making the collar midsection, and the construction method of the extreme and mean ratio adjustment, can be adjusted for all measurements, thereby providing the establishment of a design criterion and the possibility of the standardization of construction methods. The production method for the basic pattern design is as follows: 1) The conic angle for the Jo-go-ri's girth, length end neck width is fixed at 70(72) degree. 2) The radius of the cone is sleeve length. 3) The bust girth calculation formula is B/4 + 2.5 cm. 4) The armhole formula is B/4 + 2.5cm. 5) The neck width formula is B/10. 6) The ratio of the collar junction{width of collar(Kit) + width of collar strip(Dongjung) to the gusset length is 5:8. 7) The length of the side seam is a length intersecting the armhole line and the conic radius of sleeve length, that is an arc that exceeds the length of the Jo-go-ri's midsection.

Different CAx systems are being utilized throughout the product lifecycle due to the practical reasons in the supply chain and design processes. One of the major problems facing enterprises of today is how to share and exchange data among heterogeneous applications. Since different software applications use different terminologies, it is difficult to share and exchange the product data with internal and external partners. This paper presents a method to enhance the CAD model interoperability based on feature ontology. The feature ontology has been constructed based on the feature definition of modeling commands of CAD systems. A method for integration of semantic data has been proposed, implemented, and tested with two commercial CAD systems.

In this paper, we have proposed a design method for standardization of weapon information exchange between a weapon control computer of guided missile system and a high echelon command and control system. Because the weapon control computer based on diverse combat platforms is operated with several kinds of a high echelon system, it is necessary to provide a standardized design method for weapon information exchange between mutual system. In fact, it is possible to standardize a interface design specification of weapon information message because weapon information message is closely related to standard tactical data link message. It is essential that the interface design specification of weapon information is submitted to that of tactical data link information. It seems that this interface design specification is very useful in development process of the future weapon system.

소형위성은 저비용으로 단기간에 개발이 가능하기 때문에 이를 통해 폭 넓은 우주 연구를 수행할 수 있고 다양한 분야의 활용 가능하다. 소형위성은 빠른 개발이 가능한 이점이 있다. 따라서 신속 대응 우주 구현이 주목됨에 따라 소형위성의 역할이 급속히 증가하고 있다. 하지만 소형위성은 기존의 위성에 비해 크기나 전력의 제약이 많기 때문에 고성능의 안정적인 시스템을 기대하기는 어렵다. 이러한 문제점을 해결하고 빠른 개발을 위해 표준화와 모듈화 설계가 필요하다. 모듈화는 플러그 앤 플레이(Plug-and-Play)를 지원하여 수일 내에 인공위성 제작 및 시험을 가능하게 한다. 이러한 모듈 간의 원활한 데이터 통신을 위해서는 데이터 버스의 표준이 요구된다. CAN 통신 방식은 플러그 앤 플레이에 가장 효과적으로 대처 할 수 있는 통신방식으로 꼽힌다. CAN은 높은 신뢰성을 가지며 분산 시스템을 지원하여 위성의 호환성을 높여준다. 따라서 시험이 용이해지고 짧은 기간에 고성능의 안정적인 위성 개발이 가능하게 된다. 본 논문에서는 모듈화 방식의 소형위성 개발 방안에 대해 제안하고, CAN을 데이터 버스로 적용하여 소형위성 내부 데이터 인터페이스 버스를 설계하고 시험을 통해 적합성을 분석하여 기술하였다.
