In this study, we used the 3D simulation program to create bodice patterns for adolescents boy students and analyze the fitting and air gap through 3D simulation. The purpose of this study was to select the bodice pattern method that best suited the body shapes of the adolescents male students. The subjects of this study were the French E pattern, Japanese N pattern, and Korean industrial L and J patterns. The applied size was the sixth Korean human body size survey data of 2010 Korea. The age range of the subjects was 13-18 years. DC Suite Program Ver. 5.1 was used, and SPSS 23.0 program was used for data analysis. As a result of comparing the shapes of the bodice patterns in the 3D simulation program, the E pattern had two waist darts on the front and one shoulder dart and one waist dart on the back, and the J and L patterns only had one dart on the back. The N pattern had no darts on either the front or back. As a result of examining the appearance evaluation of the pattern, air gap, color distribution, and clothing cross-section, the E pattern was evaluated as the closest to the body, and the N pattern was evaluated as the pattern with the largest allowance. The J pattern was evaluated as the best fit for body shape of the male adolescents. However, it is necessary to develop a pattern system by adding extra ease in setting the center front length.

This study aims to analyze the patterns made with knitted jacquard and intarsia techniques to provide essential data to help plan different knitwear designs using the techniques and patterns. Based on approximately 3,000 jacquard and intarsia knitwear published in the four significant womenswear collections over the past decade, eight main pattern types were classified, and each characteristic was analyzed. Firstly, it is a logo and symbol type pattern that appears mainly as a means of emphasizing a brand. Secondly, it is a traditional pattern with settled patterns from the past to the present. Third, it is a geometric pattern that appears both typically and atypically in various forms. Fourth, an abstract pattern type does not show a precise form or motif. Fifth, it is a colorful and diverse flower and plant pattern. Sixth, it is a landscape pattern that expresses nature and living space. Seventhly, it is an animal pattern type that expresses the appearance of an animal or the shape of the. Finally, it is a caricature pattern type using characters and various cartoonish motifs. Based on the analysis results of this study, creative and diverse design development of Jacquard and Intarsia knitwear and development of the knitwear market will take place.

This study aims to develop a bodice and a jacket in 3D of the late 19th to early 20th based on the pattern drafting book of Gordon S. S., which contains body measurement method and pattern drafting system. The findings of this research are as follows. First, female tops of the late 19th to early 20th century are categorized as outer, jacket, vest, and bodice. Of these, this study highlights the jacket, which can be divided into 4 types: 4 kinds of basic jacket, 2 kinds of riding jacket, bolero jacket, and newmarket jacket. Second, by referring to Gordon's pattern drafting system and book, a bodice was developed in 3D format based on the adherence to the following steps: analysis of the pattern drafting system, pattern drafting, 3D virtual simulation, 3D virtual fitting analysis, and the pattern correction. A bodice pattern corrected by 3D virtual clothing simulation results was proposed. Last, a basic sleeve and collar pattern for a basic jacket was drafted, which was followed by the correction and transformation of the bodice pattern. The jacket developed shows great fit except for the issues at the armhole line and shoulder, which were caused by the unique shape of the sleeves(big sleeve head) of the time. The study attempted to develop the past costumes in 3D, providing the basis for interdisciplinary research in the field of fashion history field and suggesting a new approach for the virtual restoration of costumes. Future studies should target to 3D virtual simulation in accordance to the 3D avatar pose in the developed virtual costume.

The purpose of the present study is to develop a grading deviation, which is appropriate for the body type of women in thirties, by analyzing the three-dimensional body type. The materials for the study were adopted from the body measurement data of women in the age group of 30 to 39 years old, provided from Size Korea. By reflecting the factor analysis results using the three-dimensional shape measurement, deviations were derived. First, six factors influencing the changes in human body shape were derived as waist-hip length factor, bust-waist shape factor, back protrusion back shoulder factor, bust length factor, shoulder length factor, and frontal waist dart factor. The bust size and height, which can be easily utilized for the top original grading, were used for deriving a regression formula, and the deviation was set in accordance with the result. Second, by applying the deviation which reflects the changes in the body shape, the crimps which were generated due to the application of existing deviation were remarkably reduced, indicating that the grading of the present study is more fitting than the existing one. The deviation derived by the analysis of actual increase and decrease of body size was more fitting than the existing one. This was proved by actual wearing experiment, which represents the significance of this study.

Restenosis symptom, which is well known as a problem of stents, is due to the recoil and expansion pressure depending on shapes of stent. In order to reduce the effect of recoil problem, study on pattern and shape for the stent is required and the expansion pressure and recoil should be evaluated. This paper aims at evaluating mechanical characteristics of stent used in surgery for vessel stenosis. The expansion process of coronary artery stent in vessel for two models including the Cypher$^{(R)}$ from Johnson & Johnson$^{TM}$ and a suggested model were simulated using the Finite Element Analysis. Comparison of the directional recoil simulation results was made. The issues in the deformed shape of vessel and recoil of Cypher$^{(R)}$ were partially resolved in the suggested model. Therefore, the shape design suggested in this paper was able to reduce the restenosis symptom.

건축디자인을 평가하는 방법에는 상당히 맡은 요소를 고려 할 수 있다. 기능성, 구조성, 형태, 환경 등 다양한 요소를 고려하여 최종의 디자인을 생산해 낸다. 여기서 computer와 같은 자동화된 기계에 의해서 디자인이 생성된다면, 그 결과는 경우에 따라서 무수히 맡아 우리 인간의 평가 능력 범위를 넘는 수 가 있다. 따라서 디자인을 자동으로 생산할 뿐 만 아니라 자동으로 최선의 결과물을 자동적으로 평가하여 선택하는 것도 상당히 중요하다. 본 논문에서는 상기에서 언급한 요소 중 미학적 특성을 기계가 자동으로 평가하여 최적의 결과물을 선택할 수 있도록 평가 방법을 제시하였다. 평가 방법은 고전적으로 내려오는 미적 평가방법의 하나인 질서와 무질서의 상관 관계를 측정하는 것으로 이는 형태요소와 공간관계를 나타내는 형태 디자인 지식의 스키마적 표현을 적용한다.

The characteristics of arc pressure, current density and heat flux distribution are important factors in understanding physical arc phenomena, which will have a marked effect on the penetration, size and shape of a weld in TIG welding. The purpose of this study is to find out the effect of the heat flux on the melting efficiency and penetration shape in TIG welding using the results of the previous investigators. The conclusions obtained permit to draw a proper method which derived the heat flux distributions by arc pressure distribution measurements, but previous researchers calculated heat flux and current distribution with the heat intensity measurements by the calorimetry. Heat flux of Ar gas arc was concentrated at the central part and distributed low from the arc axis to the radial direction, that of He mixing arc was lower than that of Ar gas, and it was wide distributed to radial direction. That showed a similar characteristic with the Nestor's by calorimetry calculated values. Throughout heat flux drawn in this study was discussed melting efficiency and penetration shape on Ar gas and He mixing gas arc.

Demands and attempts to express Korean traditional beauty are increasing. Some schools choose the uniform in designs expressing the image of Hanbok, but recently there is a few increment of wearing the uniforms. For the improvement of the uniforms, first of all, the shape and the clothing materials of the uniforms should be considered. We have compared and analyzed the shape and the clothing materials of the uniforms reflecting the image of Hanbok, according to seasons and clothing items. The uniforms reflecting the image of Hanbok were worn in eight schools and all of them are Saenghwal Hanbok style. The shape of Saenghwal Hanbok school uniforms showed both Korean style and western style characteristics. Korean style characteristics were expressed through the appearance-related parts while western style characteristics showed through the performance-related parts such as open/closure method, armhole pattern and straight sleeve line. It was shown that girls' uniforms are more diverse and similar to the western style uniforms than boys' uniforms. It was found that most of the clothing material were synthetic fiber or mixture of natural/synthetic fiber, and polyester was shown to be used most.
