The study with the subjects of the female consumers of the fomentation rooms in their 20s, this research made an investigation of the fomentation wear. Also, dye-fastness experiments of the wear's colors against washing and sweating were held. The following are the conclusions; 1. Survey Results of the Present Situations of Fomentation Wear Designs of the fomentation wear, 88% belonged to a T-shirt (upper clothes) and knee pants. The primary colors of the wear were in the order of gray (37.5%), white (31.3%), orange (25%), indigo (18.8%), and yellowish (18.8%). 43% of the wear companies used the same color for two-piece clothes, and 57% employed different colors for upper and lower clothes. 2. Consumers' Attitude about Fomentation Wear The key problem in the attitude to the wear, 25.9% pointed out the worries about physical exposure (like breasts and legs) owing to the improperness in designs and sizes. 32.8% of the subjects were also worried about physical silhouette exposure following sweating. The need for design improvement was felt as the subjects expressed their intention to use better fomentation wear in design and materials if the fare is higher. 3. Experimental Results of the Dye fastness of the Fomentation Wear Dye-fastness experiments by sweating appeared in the order of gray > white > pink. The results by washing were gray & white > pink. As laundry grew in number, the grade of dye fastness fell a little bit. In the fomentation environment with more laundry and more perspiration, dye fastness of the wear's colors against washing and sweating should be fully considered.

The mechanical and electrical properties of ball grid array (BGA) solder joints were measured, consisting of Sn-3.5Ag, with organic solderability preservative (OSP)-finished Cu pads and Electroless Nickel/Immersion Gold (ENIG) surface finishes. The mechanical properties were measured by die shear test. When ENIG PCB was upper joint and OSP PCB was lower joint, the highest shear force showed at the third reflow. When OSP PCB was upper joint and ENIG PCB was lower joint, the highest shear force showed at the forth reflow. For both joints, after the die shear results reached the highest shear force, shear force decreased as a function of increasing reflow number. Electrical property of the solder joint decreased with the function of increasing reflow number. The scanning electron microscope results show that the IMC thickness at the bonding interface gets thicker while the number of reflow increases.

이러닝 학습은 다양한 목적을 지닌 많은 대상들에게 눈부실만한 기여를 하고 있음에도 불구하고 이러닝의 특성을 가장 절실히 필요로 하는 장애인과 노인 등의 소외된 사람들에게 혜택을 주지 못하고 있다는 점은 안타까운 일이다. 이러한 현실에 대하여, 그동안 정보통신기술분야에서도 소외된 대상들을 고려한 접근성 관련 제도적 개선이 이루어져 왔다는 점을 상기한다면, 자성만이 아니라 그 이유를 조사할 필요가 있다. 따라서 본 연구의 목적은 이러닝 기업 CEO의 인식을 조사하여 웹 접근성과 관련한 제도적인 여건 속에서도 학습 환경에서는 여전히 접근성 개선이 이루어지지 않는 이유를 찾아보고 개선 방안을 제시하는 데 있다. 위의 목적을 위하여 현업에 종사하는 운영자와 개발자들을 대상으로 보편적 교수 설계을 위한 이러닝의 접근성 관련 인식을 조사하였다, 그 결과 이러닝 접근성에 대한 CEO의 인식은 매우 저조하며, 중요성에 대해서는 공감하나 비용적인 부담으로 인해 보편적 이러닝 콘텐츠 개발은 불가능하다고 생각하고 있었다. 이러닝 기업 CEO의 낮은 인식은 곧 개발자와 교수설계자들에게 접근성 기술 적용의 필요성을 강조하지 않는 결과를 초래하고 있다. 이에 대한 개선을 위해서는 우선 정부와 관련기관의 적극적인 홍보와 제도적 장치가 필수적이며, 현재 제공되는 이러닝의 접근성 개선을 위한 연구와 지원방안이 필요하며, 구체적으로는 보편적 학습설계와 접근성에 대한 교육과 확산을 위한 대안이 필요하다.

With the subjects of male consumers in their 20s to 40s living in the Ningbo area in Zhejiang Province, this study aims to investigate into the reality of their purchase attitude and size fitness of ready-made suits. The results are as follows; Looking into their demographic characteristics, 70.6% of the subjects were twenties, 60.6% were single, and educational career stood in the order of college, middle school, and high school graduation. They were largely absorbed in free trade, followed by teaching, commerce and service industry. 59.6% of them were Zhejiang Province belongs. One to two thousand yuan was the greatest portion of their monthly income. As for their purchase attitude of ready-made suits, they thought higher of material, quality, activity, and solidity than of design. They preferred to buy clothes at a department store. There was significant difference between purchase frequency and purchase price according to monthly income and jobs. Concerning brand recognition, the Chinese subjects favored "Youngor." Though Korea's brands were very lowly recognized, Korean products received really high recognition. Compared with China's brands, they found foreign brands excellent in design, followed by material/matter, wear, and sewing. As to their physical satisfaction and the size fitness of clothes, most subjects felt happy with their sizes. Trousers and jackets were among the unfitting suit items, while the girth of waist was the least satisfactory size. Therefore, in order to raise the market occupation rate of Korean suit goods in China, more aggressive marketing strategies are required to utilize the current Korean-style entertainment and maximize concerning brand images. In particular, outstanding products in consideration of prices should be made through the proper patternmaking to reflect the body types of the Chinese.

In this study, we developed a species-specific PCR assay for rapid and accurate detection of three Xanthomonas species, X. axonopodis pv. poinsettiicola (XAP), X. hyacinthi (XH) and X. campestris pv. zantedeschiae (XCZ), based on their draft genome sequences. XAP, XH and XCZ genomes consist of single chromosomes that contain 5,221, 4,395 and 7,986 protein coding genes, respectively. Species-specific primers were designed from variable regions of the draft genome sequence data and assessed by a PCR-based detection method. These primers were also tested for specificity against 17 allied Xanthomonas species as well as against the host DNA and the microbial community of the host surface. Three primer sets were found to be very specific and no amplification product was obtained with the host DNA and the microbial community of the host surface. In addition, a detection limit of $1pg/{\mu}l$ per PCR reaction was detected when these primer sets were used to amplify corresponding bacterial DNAs. Therefore, these primer sets and the developed species-specific PCR assay represent a valuable, sensitive, and rapid diagnostic tool that can be used to detect three specific pathogens at early stages of infection and may help control diseases.

This research checked about the necessity for the development of men's dress forms in the first investigation for the educational circle and the men's wear industry. Somatotype characteristics were analyzed in the second investigation of body measurement with the subjects of 200 male adults in their twenties residing in Busan. The following are the results of the present research to develop male dress forms for patternmaking: 1. In the group analysis for the characterization of front body types, three somatotypes were found and named H, Semi X, and Y. In the cluster analysis of side body types, four types were identified: D, I, d, and q. In the combination of front and lateral body types, four kinds were chosen: semi X-I, semi X-q, semi Y-I, and Y-q. 2. Through the comparison of plane figures by the plaster method as well as horizontal and vertical cross sections by the sliding gauge method, semi X-I was finally chosen as the standard somatotype for male dress form development. 3. Compared with the sliding gauge method of the present dress forms, the research dress form reflected better the shapes of the parts of the back and hips and the position of the waist, especially for males in their 20's. In addition, the dress form in the current research had superior points in all the items of clothing evaluation. Based on the above results, the sizes and models of the men's dress forms for patternmaking were developed.

This study were to grasp the present situation of the pet wear market and the problem of pet wear, and to develop the pet wear pattern which agrees well to dog's shape and movements. We carried out survey research to analyze the actual pet wear market condition for a dog-lover, and movement analysis and sensory test to develop a pattern for Maltese which was the favorite dog among Korean. For data analysis, ANOVA with duncan test, T-test were conducted using SPSS statistic program(ver. 10.0). The results are as follows: 1. The results of the survey research, 75% of dog-lover had a pet wear and favorite was T-shirts. The problems of wearing T-shirts were 'too tight seam sleeve and bodice(front legs hole)', 'the clothes easily hang down' and 'easily taken off due to large neck size'. 2. The ease amount of the developed pattern was given according to the results of dog's shape and movement analysis, and the results of sensory test, there is a significant difference in the following items: depth of front neck line, front chest${\to}$abdomen curve, ease amount of sleeve, comfort level of leg parts. 3. The size of each parts of the developed pattern in this study were as follows : neck girth 27.0cm, body girth 40.0cm, back length 26.0cm, front leg girth 23.0cm, sleeve length 20.7cm, sleeve width 14.4cm. But, there exists some limits to generalize these results since dog's body size and shapes are various according to dog species. Therefore, further studies are needed to develop each pet wear pattern for each dog species.
