This study aims to compare the ease of shirt patterns in the men's wear market that have been constantly developing, and to analyze the fitness and appearance through the 3D virtual try-on system. The study selected three industrial patterns and two educational materials of classic-fit and slim-fit shirts for a total of ten items. The experiments involved virtual wearing, a stress contact point perspective map, and appearance evaluations. First, the ease differed significantly in the chest, waist, and sleeve cap height according to the patterns. Second, based on the stress, contact point, and transparency, there was ease in the order of Nam, D-brand, J-brand, Park, and S-brand in the classic-fit shirts while the order of D-brand, Nam, J-brand, Park, and S-brand resulted in the slim-fit shirts. Third, in the appearance evaluation, higher points resulted in the order of J-brand, Park, S-brand, D-brand, and Nam in both classic-fit and slim-fit. The results showed that proper ease differs greatly by shirt-fit and target age. Also, the shirts with more ease tended to be evaluated less favorably in the appearance evaluation. Based on the results, the study suggests that the proper ease in chest circumference is 18cm for the classic-fit shirts and 6 cm for the slim-fit shirts.

This study analyzed the lower body type of 30's Korean men to develop a slim-fit pants pattern. As the analysis data, direct measurement data of anthropometric measured value in the 6th Size Korea(KATS, 2010) was used as basic data with 481 men in 30's as analysis objects. The result are as follows. First, the result of analyzing factors for the lower body type classification indicated five factors. Second, the result of executing group analysis (with the independent variable of 5 clusters extracted from the factor analysis)classified the following three types. Type 1(36.8%) displayed a medium height of lower body type, small waist and hip, slim and fit body type with a slim shape between the knee and ankle. The shape between the waist and hip had characteristics of a slight curve and short length. Type 2(35.6%) displayed lowest height of a lower body type that was large and thick between the waist and the hip. The drop value of the waist and the hip was small; therefore, the body type was flat with a minimal curve. The underpart type (below the knee) was the thickest and the length was short. Type 3(27.7%) displayed the highest lower body type, a medium level waist size, flat and narrow waist and belly. This body type had a curve with big drop value of the waist and the hip, lower part from the hip to the ankle (including the knee) and a thick calf with along leg.

The aim of this study was to develop a body type suitable for adult men aged from their 20s to their 40s and to present a method of drafting related patterns. To this end, the somatic surface pattern data from previous studies were used. The research method involved drafting torso patterns for each type by setting and distributing the ease to the somatic surface pattern. Appearance evaluation was performed with virtual clothing. Then, the torso pattern for each body type was completed and presented as a draft method. SPSS was used for data analysis in this study. The research results are as follows. Types 1, 2, and 3 were set to 7%, 6%, 5%; 7%, 6%, 4%; and 6.5%, 7%, and 6% for chest, waist, and hip circumference measurements, respectively. The ratio of front to back was 50%:50%, 50%:50%, and 50%:50% of the spare for each body part for Type 1; 70%:30%, 50%:50%, and 60%:40% for Type 2, and 60%:40%, 70%:30%, and 60%:40% for Type 3. A tight-fit torso pattern for each body type suitable for adult males in their 20s to 40s was drafted, which was modified and supplemented through the evaluation of the first and second virtual wear. Considering the practicality of this approach, for generalization of the patterns, the items of the pattern were converted into a drafting method and presented as a draft method.

This study tried to suggest a drafting method to draft tight fit torso patterns suitable for adult males with a sway back somatotype and a bend forward somatotype by setting and distributing the ease through the completion of the somatic surface pattern using the 3D body surface segment method. It was intended to be presented as a drafting method. As for the research method, the suitability of the somatic surface patterns and the tight fit torso patterns were confirmed by the evaluation of virtual wear, and the patterns were modified and supplemented. The research results are as follows. In the first evaluation of the tight fit torso patterns, the average, for 55 evaluation items, was 3.92 points for the sway back somatotype and 3.89 points for the bend forward somatotype. In the second evaluation, the bend forward somatotype was 4.51 points and the sway back somatotype was 4.62 points. The chest circumference ease amount for the bend forward somatotype and the sway back somatotype are 6.5% (6.8 cm) and 7% (6.8 cm) of the chest circumference, respectively, and the distribution of the front and back ease is the same at 4:6 (2.72 cm:4.08 cm). The waist circumference ease amount is 6.5% (5.8cm) and 6.5% (5.6 cm) of the waist circumference dimensions, and the distribution of the front and backease are 5:5 (1.45 cm: 1.45 cm) and 4:6 (2.24 cm: 3.36 cm), respectively. The completed tight fit torso patterns were converted into institutional formulas and presented as a drafting method.

The configuration of injection molded part can be classified into primary feature and supplementary feature. Even though supplementary features such as ribs, snap fits and bosses make mold more complicated, which cause the increasement of the mold cost, supplementary features should be attached to primary features because of assembly, reinforcement, moldability and other functional purposes. But it is not easy for novice designers to design them appropriately because of the profound knowledge related to Injection molding. In this paper, the intelligent design tool called ISFD(Intelligent Supplementary Feature Designer) which supplies easy, simple, time and cost-effective design method has been studied and developed. A knowledge-based design system is a new tool which enables the concurrent design and CIM with integrated and balanced design decisions at the initial design stage of injection molding.

Carbon solid was prepared from dormant mesophase pitch (DMPP) without using a binder and its properties were characterized. DMPP powder was stabilized with air or nitric acid in pretreatment stage so that it might not soften in later heat ttreatment stage. Optimum sintering properties were obtained from carbon powder with 2.36∼2.38 of C/H atomic ratio and 1.27∼1.40 of C/O atomic ration in air stabilization. In nitric acid stabilization, optimum sintering properties were obtained when 20∼40 vol.% of nitric acid solution was used. Compressive strength increased up to 1200$^{\circ}C$ of heat treatment temperature, and the highest compressive strength and bulk density of carbon solid from DMPP were 3000 kgf/㎤, respectively. The optical properties of carbon solid obtained was fine mosaic structure. Carbon solid after graphitization showed the properties of hard carbon due to stabilization and its shore hardness was 120.

이중층 탄소재료가 콜타르핏치와 메조페이스 핏치, 인조흑연, 천연흑연과 코크스를 사용하여 제조되었다. 콜타르 핏치는 톨루엔이나 경유와 같은 유기용매에 용해되어 코팅재로 사용되었다. 메조페이스 핏치, 인조흑연, 천연흑연 및 코크에 대한 콜타르 핏치의 코팅은 X선 회절분석과 CHN 분석을 통해 확인하였다. 코팅된 탄소재료를 질소분위기의 800-100$0^{\circ}C$에서 열처리한 후 리튬이온 전지의 음극으로 사용하기 위하여 2$600^{\circ}C$에서 열처리하였다. 이중층 탄소재료의 성능평가는 동전형태의 반쪽전지를 통해 수행되었는데, 평가는 음극으로서의 충전과 방전을 통해 수행되었다. 이런 충.방전 능력은 탄소재료의 열처리 온도의 변화나 전구체의 종류에 따라 달리 나타났지만 코팅방법의 차이에 의해서는 큰 차이가 없었다. 열처리를 80$0^{\circ}C$에서 한 경우가 100$0^{\circ}C$에서 한 경우보다 높은 충.방전 능력을 나타내었고, 2$600^{\circ}C$에서 흑연화된 것보다 탄화된 재료들이 높은 충.방전 능력을 나타내었다. 결론적으로, 음극재료의 성능은 결정화도, 조성 및 탄소재료의 미세구조에 따라 달라짐을 알 수 있었다.

Most industrial products nowadays have been manufactured by being made up of many parts what these are made from various kinds of materials. These parts and goods should be disassembled simply and classified easily by material or kinds of parts for the recycling. But it is not so easy to know how to take disassembly ways and those orders must be known and also analyzed the assembled points and directions of the every part. This research presents an design process for recycling that it will be considering whole design process for recycling about easiness of disassembling units as the prior condition to reuse the parts and used material, and to reduce waste parts.
