This study is largely aimed at presenting ways to improve the working clothes and help companies create more positive images by suggesting designs of the clothes, which take into accounts the corporate image, symbolism, function and aesthetic appreciation through introduction of companies' CIP. And, it is significant to propose working clothes development condition and process with introduction of companies' CIP(Corporate Identity Program : work that systematize and simplify visually images which companies or public bodies have) A way of this study was made up with working clothes design development process which a student planned. First of all, this study looked into Company D's Corporate Identity Program(CIP) to develop the design that corresponds with the characteristics of the company's favorite design, working environment and demands of the employees. And, then, the study conducted a survey of 30 employees and intensive interviews with heads of four teams including the Safety Team, the Working Clothes Management Team and the General Affairs Team to find out the requirements of the clothes and the characteristics of the company. Based on them, the concrete image that the company pursues and the direction of design were set up through image positioning. In the end, three different concept designs were presented through image-mapping and the concrete design of each item was developed. A total of seven items including upper and lower garments (a jacket and trousers) for the spring-summer seasons, upper and lower garments (a jumper and trousers) for the winter season, cold-protecting vest and winter clothes (a coat and trousers) were presented in accordance with the three concepts. One of the concept designs, which was selected through evaluation by employees of Company D, was produced as a sample and then the final design was chosen after a discussion attended by the head of each team and representatives of the employees. Based on the aforementioned design planning, one design was selected from each of the three concept designs for production. And each of these was requested to special production enterprise and manufactured. Following the result of study, by looking into a case of a practical joint design project between a university and a company, this study suggested ideas for business to improve working clothes through the academic-industrial cooperation and presented conditions and process of design development. And, this study also aims to examine the feasibility of academic-industrial cooperation based on the cases in which enterprises and universities staged joint projects to develop working clothes.

Purpose: Autologous vessels remain the gold standard for vascular grafts in microanastomoses. However, they are sometimes unavailable and have a limited long - term patency. Synthetic vessels have high success rates in large - diameter reconstructions but failed when used as small - diameter grafts due to graft occlusion. It has been proved that endothelial cell seeding improves prosthesis performance and long - term patency. Among polyurethane, PET and ePTFE, polyurethane has the best affinity to endothelial cells and mechanical properties closest to human vessels. We examined the ability of endothelial cells to attach to a polyurethane graft manufactured by the electrospinning method. Methods: Endothelial cells, which were cultured from porcine internal jugular veins, were attached to polyurethane grafts with an internal diameter of 3 mm. The same cells were attached to allogeneic decellularized porcine internal carotid artery grafts as controls. Both of the 10 mm - long grafts were exposed to endothelial cells in a well for 1 hour. Each well contained $2{\times}10^5$ endothelial cells. The graft materials were rotated through 90 degrees every 15 minutes in order to minimize the effect of gravity. The extent of cell attachment was examined with the MTT assay. Results: The MTT assay showed good incorporation of endothelial cells into both grafts. For the evaluation of affinity, the number of attached cells was counted at 10 fields of microscopic examination with ${\times}40$ magnification. Endothelial cells adhered more to polyurethane grafts (mean, $127.4{\pm}6.2cells$) compared to porcine artery grafts (mean $45.8{\pm}5.1cells$)(p<0.05,Mann - Whitney test). Conclusion: In this study, we attached porcine endothelial cells to polyurethane grafts, manufactured by electrospinning. The grafts exhibited a better affinity to endothelial cells than allogeneic decellularized porcine internal carotid artery grafts. It is suggested that the time required for endothelial cells to attach to decellulized artery grafts may be longer than that which is required for attachment to polyurethane grafts.

Three-dimensional body data has been used in many industry fields including the apparel industry. This research used data from a study of the changes in lower body girth measurements from a 3D scan study of 25 female subjects aged 18 to 24 in four postures; a standing posture, a $120^{\circ}$ knee bend posture, a one pace stepping posture, and a sitting posture with a $90^{\circ}$ knee bend. We used the information on the difference between standing and seated measurements to adjust ease values for pants patterns an evaluation of the appearance, and the comfort of the pants. Waist girth in the sitting posture increased 8% compared to a standing posture and the hip girth measurement increased 7%. A basic pants pattern (pants A) with 2.4cm ease at the waist and 2.6cm ease at the hip was developed and a pants pattern (pants B) was developed using the rates of lower body girth change with a 5.7cm ease (8% change) at the waist and 7cm ease (7% change) at the hip. The appearance assessment items of pants A in a standing posture were higher than pants B. On the other hand, most appearance assessment items of pants B in a sitting posture were higher than pants A, especially the ease of pants back waistline and the appearance of the whole back. Comfort assessment items of pants B in both standing and sitting postures were higher than the comfort assessment items for pants A, especially the location of pants waistline, the ease of pants at the waistline, and the ease at the abdomen. In order to find the best level of ease for better appearance and comfort in both standing and sitting postures, 20 pants were constructed with ease values at the waist and hip in increments of 1.1cm in the range between the ease values of pants A and pants B. A fit test was conducted to compare the average appearance and comfort ratings that identified the pants with the best ease values at the waist and hip. The highest total mean was achieved in the pants with a waist ease of 4.6cm and hip ease of 4.8cm.

The purpose of this study was to suggest valuable maker education programs by implementing and evaluating a Home Economics(HE) maker education program developed based on the content of "Hanbok and Creative Clothing" for high school students. The results of this study are as follows. First, the HE maker education model for high school students was designed and developed. The HE maker education model was developed by integrating and modifying the TMSI model of the maker education model and Laster's HE practical action teaching model. The HE maker education model consisted of 4 steps: tinkering(T: 4-hour class), practical reasoning(P: 3-hour class), making together(M: 4-hour class), and sharing and spreading(S: 1-hour class) with a total of 12-hour lesson plans. The theme of the developed HE maker program is 'Practice and spread of creative traditional culture of life (Hanbok)'. Second, the results of online survey of 240 high school students who participated in this maker class showed that HE maker class had positive effects in the order of experiential(4.26), cognitive(4.22), emotional(4.18), social(4.18), and practical(4.10). It is expected that the findings of this study will contribute to diversifying the curriculum of Home Economics, thereby improving the quality of Home Economics Education.

This study develops a fitted torso type basic pattern for men by utilizing 3D body scan data. Recent fashion trends are reflected in the development of the pattern. The subjects were 15 men in their 20's, who wear size 95 (M size). Body scan data was obtained through a 3D whole body scanner (WB4, Cyberware, USA), and a body surface development figure for developing male fitted torso type basic pattern was attained through the use of Rapid Form 2006 as well as Auto CAD 2006 programs. The results are as follows: A body surface development figure through body surface segment method showed high exactitude in an error range of 100$\pm$1%. In addition, it occurred in an error range of 100:1:3% because of the hard scanning conditions in the incline of the shoulder and armpit areas. However, the body surface development figure as well as the direct measurement results can be used as basic data for the given patternmaking since the error range falls into 100$\pm$3%. Dart amounts obtained from the average cross section were center back 2.2cm (24.3%), back armpit point 3.8cm (41.8%), front armpit point 3.0cm (33.9%). As shown the jacket pattern, the biggest dart amount was portioned out at the back armpit point. The drafting equations for the development pattern acquired are as follows; Full width=C/2+5cm, back length=height/4-1cm, armhole depth=(C/10+12cm)+3cm, back width=2C/10+2cm, front width=2C/10. The development pattern was a fitted torso basic pattern that was composed of 3 pieces, so it would be very useful in developing shirt or jacket patterns. According to the results of the evaluation of the developed pattern appearance, it obtained higher scores of over 3.5 points in almost items, meaning that the developed pattern is appropriate for a male fitted torso type basic pattern. It suggests a possibility of patternmaking from a body surface development figure in 2-D to prototype.

In order to develop a bodice prototype suitable for obese women in their 20s, this study compared and analyzed a total of five pattern system methods, including prototype of France and Japan, one prototype for education in Korea and two prototype for industries in Korea. Through this, this study attempted to investigate the bodice pattern system suitable for the development of plus-size women's clothing. For the pattern drafting, pattern 1 was applied with the most body dimensions such as interscye fold front, interscye fold back, bust circumference, neck circumference, and waist back length, and pattern 2, pattern 4, and pattern 5 were made based on bust circumference and waist back length. As a result of the appearance evaluation, Pattern 3 was evaluated as the best pattern in all items except for the suitability of the center front length and the suitability of the side waist circumference position. However, it was evaluated as inappropriate in items such as the vertical side line, the suitability of the side waist circumference line position, the suitability of interscye fold back position and shape, and the suitability of the back shoulder dart position. Most of the pattern drafting methods are based on the size of the bust circumference, but other institutional methods are considered necessary when setting the neck circumference and shoulder length for 20s obesity women. In addition, it is also required to develop a method for setting the front center length due to abdominal protrusion.

This study was intended to develop a prototype of new Hanbok Cheollik one-piece based on design extracted through a preference survey on new Hanbok Cheollik one-piece. Through this, it was intended to provide information on patterns that are fundamental to the production of new Hanbok Cheollik one piece. The pattern of the experiment was produced by modifying D pattern, which was selected as excellent in the comparison of commercial Cheollik one-piece patterns. The SPSS 26.0 program was used to analyze the appearance evaluation of patterns. As a result of the 1^st evaluation of appearance and garment pressure, the shoulder, sleeve length, skirt length and sleeve width required modification, reducing the sleeve length by 8.0cm and the sleeve width by 1.0cm in total. The length of the skirt was reduced by 5.0cm and the shoulder end point was reduced by 0.5cm on both sides to modify the shoulder width. As a result of the 2^nd evaluation, the waist area, sleeve width, and skirt wrinkles were required to be corrected, reducing 2.0 cm waist width and 1.0 cm sleeve width and removing wrinkles on the front center and side area. The final pattern was highly appreciated. In future studies, it is thought that research should be conducted through study of Cheollik one-piece pattern according to material and age and the actual wearing experiment according to fabric and age.

This study compares fashion leaders and market mavens by examining the demographic characteristics of fashion leaders and market mavens and how they differ in their evaluation of store and shopping related attributes. Data originated from a national consumer mail survey in the United States. The survey included items measuring market mavenism, fashion leadership, store evaluative attributes, and personal information. Responses from 380 consumers were used for data analysis. Female consumers were found to be more active in word-of-mouth activities in general. Young consumers were more inclined to express fashion leadership while age was not related to market mavenism. A lower level of education increased tendencies for both market mavenism and fashion leadership. In terms of store evaluative criteria, the majority of items in the survey were more important as fashion leadership and market mavenism tendencies increased. Interestingly, the need for knowledgeable or helpful salespeople did not increase with fashion leadership tendencies. Also, fashion leaders were interested in easy return of merchandise and were likely to spend more time in the stores. This study sheds important light on how fashion leadership differ compared to market mavenism. By simultaneously examining fashion leadership and market mavenism using a strong sample base, this study provides sound evidence of how consumers interested in fashion may have differing needs for shopping.

Subjective touch sensation for Korean traditional silk fabrics was evaluated, in order to compare tactile sensory aspects of Korean and American subjects and to determine mechanical properties of the fabrics affecting the sensation psychophysically. Eight aspects of touch sensation including hardness, smoothness, coarseness, coolness, pliability, crispness, heaviness, and thickness were rated by semantic deferential scale. The mechanical properties of fabrics were measured by Kawabata Evaluation System (KES). Both of Koreans and Americans showed fairly similarities to each other in subjective smoothness, coarseness, and crispness. On the contrary, as for coolness and pliability, Koreans were found as feeling the silk fabrics more sensitively than Americans were in that they rated some of modified leno fabrics as very cool and stiff in touch. Coolness and pliability by Koreans were affected mainly by surface and bending properties while those by Americans were determined mostly by compressional and tensile characteristics as well as sulfate properties

The purpose of this study is to investigate fashion product image evaluation according to life-style groups of middle-aged women. The subject of investigation was 352 middle-aged women from 35 to 59 living in Daegu by random sampling method in April and May, 2005. The investigation was carried out by questionnaires which were composed of 3 sections: Fashion product image measure, Life style research and demographic variables(age, academic background, occupation, monthly clothing allowance, monthly income). The statistical methods to analyze the data were frequency, percentage, average, factor analysis, cluster analysis, ANOVA, Duncan's multiple range test. The results are summarized as follows: 1. As a result of factor analysis for fashion product image, the four factors including noble image, bold image, practical image, female image were extracted. 2. Middle-aged women were classified into four life-style groups including tradition oriented group, negative oriented group, activity oriented group and appearance oriented group. 3. Significant differences in fashion product image preferences according to life-style groups were found. Tradition oriented group preferred noble image and practical image. Negative oriented group tended to pursue practical image. Activity oriented group pursued a bold image. Appearance oriented group liked a noble image the best and then noble image, bold image in order.
