This study developed an ergonomic Korean female military winter jacket and (inner and outer) pattern in in order to increase dimension and operational suitability for military missions. First we developed the 1st development pattern and sample jackets with improved dimensions and operational suitability based on a previous investigation of fitness and motion suitability of Korean female military winter jackets (inner and outer) and motion suitability by a wearing test. The evaluation result of fitness for the 1st development pattern were over 4.0 (5.0 Likert scale) for both the inner and outer jacket, a positive result and the result of motion suitability were over 3.5 in both the inner and outer jacket except for the neck front part by collar height. However, we did not modify the collar height because decreases in warmth and military regulations. We also evaluated appearance by experts that showed good results in both the inner and outer jacket. Finally, we developed a final pattern based on evaluation results and military regulations. Existing military uniform research was conducted mainly on male soldiers. Beginning with this study, we expect to expand research on the development of military uniform patterns suitable for a female soldier body type.

Recently, design patterns have been known to be highly effective and practical. Design pattern is a collection of collaborating classes that captures the application independent behavior of system in a particular domain. By using design pattern, the development time and software quality can be greatly increased. However, systematic development process and detailed instructions of building design patterns have not been studied enough. In this paper. we propose practical intranet structure modeling technique that are based on design pattern. The proposed process consists of the four typical software development phases; analysis, navigation, interface, behavior domain design, and each phase is defined as a logical sequence of development tasks. Since the proposed process is based on design pattern foundation, and can be efficiently produced by applying this process.

The development of foundation garment pattern on the typical adult women's body was carried out. By means of the flatted body surface shell, the foundation garment pattern was developed. And its fitting test also performed. The results of this study can be summarized as follows; 1. The investigated Foundation basic pattern was made by the allowing the maximum bust size without any surplus since it was based on the tight-fitted model drawing technique. The investigated the completed pattern was designed in three parts of front and back body, including bust. 2. The result showed by overlapping the torso basic pattern foundation and body surface development selected from body almost the same except for the shift of dart position. 3. The result by overlapping basic pattern 3 existing basic patterns. On the basis of top-bust line showed that the setting up the volume of dart of bust and its waist affect the appearance of model. Especially, it was found that the above result was related to the bust and under bust line. 4. The result of the wearing test of 3 existing basic patterns and basic pattern of this study revealed that the mean values of whole items were higher than average in type P and type E. The fitting & position of under-bust line and extent of wrapping bust showed the high points in the current study and type of P. The result of evaluating the whole appearance in three points(front, side, back) showed different according to the every basic foundation garment pattern.

We in this paper propose a prognosis graph, analyzing prognoses of each pattern described in the Korean medicine literatures. This graph is represented as the integrated graphs about knowledge of patterns and their transitions in the prognoses, where a node becomes a pattern name and a edge becomes a transition between patterns, along with a condition with respect to cause or mechanism of the pattern. The knowledge of prognoses which a pattern is transit into another pattern can be identified at a glance by using this model. We also construct a upper-level prognosis graph, excluding five viscera and six entrails from the model. This upper-level prognosis graph contains the conceptual knowledge than clinical one so that it may be helpful to students and researchers in the Korean medicine fields.

Kimono sleeves have continuously appeared in modern fashion as a design motif and this trend has become increasingly prevalent recently. However for research in the area of clothing composition for kimono sleeves in Korea, there has been a lack of development of master patterns based on basic data from the analysis of the standard body type of Korean people and finalized designs based on comparative experiments and analysis of pre-existing research Thus, there is no ideal master kimono sleeve pattern development research based on the examination of the results of the analysis of the standard body type of Korean people. Therefore by recognizing the importance of developing a master kimono sleeve pattern, this research aims to present a practical master kimono sleeve pattern for the standard body type of someone in their 30s. First, the four master patterns were collected and a dressing evaluation was conducted, and by selecting and improving one of these master designs, a final research master pattern was developed after a second dressing evaluation. Through this research, it was possible to design a master kimono sleeve pattern appropriate both externally and functionally for the standard body type of someone in their 30s, which has not been a consideration in previous research.

When we develop the tight-fit 2D pattern from the 3D scan data, segmentation of the 3D scan data into several parts is necessary to make a curved surface into a flat plane. In this study, Garland's method of triangle simplification was adopted to reduce the number of data point without distorting the original shape. The Runge-Kutta method was applied to make triangular patch from the 3D surface in a 2D plane. We also explored the detailed arrangement method of small 2D patches to make a tight-fit pattern for a male body. As results, minimum triangle numbers in the simplification process and efficient arrangement methods of many pieces were suggested for the optimal 2D pattern development. Among four arrangement methods, a block method is faster and easier when dealing with the triangle patches of male's upper body. Anchoring neighboring vertices of blocks to make 2D pattern was observed to be a reasonable arrangement method to get even distribution of stress in a 2D plane.

This study is to develop tourist souvenir which designed image of butterfly, the symbol of Hampyeong Butterfly Festival, using natural dyeing product, the specialty of Namdo region. Results of market survey of tourist souvenirs for Hampyeong Butterfly festival showed that souvenirs of butterfly design sold in market which were not discriminated from that of general products and locality or characteristic of the region could not be exhibited. According to the results of market survey, design of souvenirs of Hampyeong Butterfly Festival is as follows; Butterfly pattern of hinge and Dangcho pattern are developed to graphic motive of modern sense with traditional beauty to make design which can be consumed by modern consumers in their actual life and then proper pattern is planned by combining, repeating and disassembling them. Such a pattern is applied to souvenirs like T-shirts, necktie and scarf to make tourists feel identity and unification of the festival visually. In addition, design of souvenirs was made to be coordinated with casuals. Therefore, visual factor could be extracted from Korean cultural heritages suitable to concept of local festivals and it is considered that ways of commercialization and development of traditional pattern suitable to consumers' demands can be suggested.
