The purpose of this study is to improve the classic jacket pattern for Korean young men whose chest circumference is 91~94cm, status is 170~175 cm, and drop value between chest and waist circumference is 15. The study was carried out by the following procedures. 1. Through the comparative investigation on the conventional classic jacket patterns of Hyung-sook Lee's, 문화's in Japan, and SMA's and the clothing experiment, the characteristics of every three patterns were found. 2. According to correct the unsuitable point in Hyung-sook Lee's pattern which was found more suitable than other two patterns and to refer to the product size of the ready-made classic jackets for men, the new suitable classic jacket pattern was achieved. 3. The sensory evaluation for appearance and comfort and one to one comparison was applied to evaluate the new classic jacket pattern by comparing with the Hyung-sook Lee' s jacket pattern. From the result of the sensory evaluation and one to one comparison, it was found that the new classic jacket pattern was more suitable for appearance and comfort. 4. From the result of this study, the suitable surplus of men's classic jacket at present is about 23~24cm on the chest circumference, 31~32 cm on the waist circumference, 14~15 cm on the hip circumference, 13~14 cm on the upper arm circumference, and 14 cm on the wrist circumference and the ease is about 3.5 cm on the armhole circumference. This size is not the absolute size but it helps to make the surplus in any other clothes for Korean young men.

Body image is important as it is related to self-esteem and can be enhanced by clothing and the degree of enhancement is related to clothing fit. The purpose of the paper is to find the adequate ease distribution of jacket pattern for the obese women who want to slenderize their shape by optical illusion. Subjective evaluation of the visual appearance we collected and, at the same time, 3D clothing air volume was observed for the nine types of experimental jackets with different ease distribution. As results it was found that jacket pattern for the obese women is that the front width of pattern is wider than what of back width in waist and abdomen. It was also noted that there was distance between clothing and skin in the girth around hip of jacket. 3D scanner clearly demonstrated the distribution of ease is useful to find the pattern variables responsible for the slender appearance of the obese women. The ready-to-made clothes for the obese women's clothing should be manufactured systematically in due consideration of the diversity and scarcity of the obese women's body shape.

This paper presents the robot vision control schemes using Extended Kalman Filter (EKF) method for the slender bar placement in the appearance of obstacles during robot movement. The vision system model used for this study involves the six camera parameters($C_1{\sim}C_6$). In order to develop the robot vision control scheme, first, the six parameters are estimated. Then, based on the estimated parameters, the robot's joint angles are estimated for the slender bar placement. Especially, robot trajectory caused by obstacles is divided into three obstacle regions, which are beginning region, middle region and near target region. Finally, the effects of number of obstacles using the proposed robot's vision control schemes are investigated in each obstacle region by performing experiments of the slender bar placement.

This study was to develop an ergonomic Korean male military winter jackets (inner and outer) pattern. First, we developed a prototype pattern and sample jackets based on a previous investigation for fitness and motion suitability of Korean male military winter jackets and evaluated fitness and motion suitability by a wearing test. The evaluation results were positive with an over 3.0 (5.0 Likert scale) for both the inner and outer jacket. However, a relatively low score was shown in the sleeve length and collar front height at the inner jacket and shown in hem circumference, neck circumference, elbow and front neck at the outer jacket. Next, we developed the secondary pattern and sample jacket reflecting the prototype evaluation result and executed expert evaluation. The result showed that the ease amount was appropriate (except for the collar back height) and the appearance was good. Finally, we developed a final pattern that showed good results after evaluation at a Korean military army base.

In injection molding process, the appearance quality issue occurs in most injection molded article. One of thermal designs for the mold was performed by increasing the cavity wall temperature with being as uniform as possible in any position. On the basis of the practical evaluation, the cavity wall temperature and finishing machined cavity surface under the optimum processing conditions are the most significant factors to avoid the appearance issue on the plastic part for a good cosmetic quality. Also, the wrong choice of gate type and location can have a considerable effect on the quality of a molded part and it's so important to keep the correct runner balance from each cavity. We've proposed the education training model of the practical tool technology course for the field oriented education to improve practical tool technology ability and optimized tooling design for injection molding quality which can be performed at the workplace substantially.

Microbiological and sensory evaluations of chicken wings treated with acetic acid and trisodium phosphate(TSP) during retail(1${\pm}$2$^{\circ}C$) and refrigerated storage(4$^{\circ}C$). Chicken wings(average weight of 15${\pm}$2g per leg) were treated with 0.5∼2% aerobic plate counts(APC) on the surface of chicken wings for storage of 16 days at 4$^{\circ}C$. During storage of 12 days at retail store(1${\pm}$2$^{\circ}C$), the treating chicken wings with 7.5∼10% TSP solutions for 10 min showed significantly inhibitory effect in preventing the growth of aerobic microbes. For odor and appearance scores, chicken wings treated with 0.5∼2% acetic solutions resembled untreated wings for storage of 16 days at 4$^{\circ}C$. However, both odor and appearance scores of chicken wings treated with 2.5∼10% TSP solutions were similar to those of untreated wings for storage of 4 days, and a higher in the storage of beyond 8 to 12 days at retail store.

We have investigated the luster of modified cross-sectional fiber fabrics as one of the essential quality estimates for clothing development. We have confirmed an objective evaluation method, and have determined the experimental luster char­acteristics of modified cross-section fibers. The cross-section of the fibers in a fabric affects the appearance of a textile. We used the image analysis method to investigate the luster to determine the critical factors influencing the appearance of modi­fied cross-section fiber fabrics. For similarly structured textiles in a component fabric, clear differences were observed in the fabric weave, density, percentage, and total area of blobs, which is image region. Color played a decisive role in the luster of the textiles, and luster was not significantly influenced by the modified cross-section fabric weave. In addition, the degree of luster did not increase in the order plain to twill to satin for modified cross-sectional fiber fabrics. All the split-type microfi­bers exhibited higher numerical luster values (percentage of pixels, and number and total area of blobs) than sea-island microfibers did. The degree of luster of the modified cross-sectional fiber fabrics was not high at specular reflection angles.

With suffering financial crisis in 1997, Korea's fashion market has grown in the direction that satisfies the reasonable price and diverse consumer's sensitivity and needs. The aim of this study is to examine whether the cutting portion in the waist line is surely necessary for designing the jacket pattern in men's wear, by closely examining the effects of the cutting portion in the waist line on the external appearance and functionality given designing the jacket pattern in men's wear for the standard body type in 20s. The results of the study are as follows. As a result of evaluating the external appearance, when having evaluated by dividing into 14 items such as the whole surface, the side, and the back side, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items and, the significant difference was indicated in 10 items except 4 items. As a result of evaluating performance, the experimental clothing, which wasn't cut the waist line, obtained the highest mark in 13 items among 25 items in the total. Next, the cutting portion in the waist line obtained the highest mark in 10 items for the experimental clothing with opening in 1.0cm. The next was indicated to be in order of the experimental clothing with 1.5cm and the experimental clothing with 0.5cm. Given seeing the above result, the cutting portion in the waist line given designing the jacket pattern for the standard body type in 20s could be known that the experimental clothing with the most excellent mark in the evaluation of performance was all the experimental clothing with 0.0cm whose waist line wasn't cut.
