This study investigated the casual jacket design preferences of women aged 50s and 60s and suggested a prototype design for functional clothing. All age groups liked the casual jacket with a length between the waist and hip, a convertible collar, and a single-breasted design. Those in their 50s preferred fitted or semi-fitted casual jackets while those in their 60s preferred semi-fitted casual jackets. Although, there were significant differences between the preferred jacket designs and ready-made brand jacket designs, most brand jacket designs were casual, semi-fitted, middle-hip length, single-breasted, and with stand-rolled or convertible collars. The analysis of the sleeve styles in brand jackets showed that consumers needed designs that are more decorative. Fashion designers for senior citizens need to design elderly clothing that is comfortable, fashionable, functional, and considers a universal design for ease of clothing function. It will also make the senior citizen fashion market more appealing to consumers. To provide jacket designs for senior citizens, we suggested casual jacket designs for embedding a functional device as well as a new jacket design library for women in their 50s and 60s.

This study aims to develop a spring/fall motorcycle jacket for quick service transporter. Depending on the results of the previous research, this study produced the tested jacket which was improved in material, pattern, and design. For the tested jacket, 100% polyester fabric excellent in strength, durability and abrasion-resistance was selected as a major material, and Cordura was used as a partial material to improve the strength and abrasion-resistance of the sleeve side lines, elbow and shoulder areas. The retro-reflection material was applied partially in order to improve visibility of the jacket in the night or in a dark place. A total of 7 pockets were composed in the jacket for the sufficient storage spaces. The functional design elements such as the 2-way zipper and the placket at the center front, the action pleats at the upper part of back armholes, the pit-zip at armpit were applied. In addition, the sleeve pattern was bent with the shape of elbow curvature in time of driving and the back length of the jacket was lengthened 4cm. As a result of the appearance assessment, there was a significant difference from the existing jacket in all items but chest size, shoulder width, cuffs circumference, and jacket hemline circumference. In motion adaptability and field activity appropriateness assessments, the assessment grade for all items was found to be commonly higher than that of the existing jacket, and thus, the tested jacket was assessed to be suitable for a motorcycle jacket design for the quick service transporters.

The purpose of this study was to investigate the result of a market research on men's jacket in their age of 25 to 35, who wear fitted jackets most, and to examine the comparative analysis of pattern and the wearing evaluation between classic jacket and fitted jacket. The results are as follows; Firstly, according to the results of a market research, 32.0% of the target owned fitted jackets, and 28.7% expressed their desire to buy only fitted jackets. This means their concern and preference for fitted jacket with which they could show up young, fresh and slim look are as high as those for classic jacket. Secondly, classic jacket showed the higher value than fitted jacket in such items as chest girth, waist girth, hip girth, sleeve's hem girth, jacket length, shoulder length, side seam length, and across shoulder point length. On the other hand, fitted jacket showed the higher value than classic jacket in back armhole length, front length, collar point length and sleeve's vent length. Thirdly, classic jacket was larger than fitted jacket in 1/2 chest girth(1.0cm), 1/2 waist girth(2.0cm), 1/2 hip girth(1.0cm), back width(0.5cm), front width(0.5cm) and side width(1.0cm). However, fitted jacket was higher than classic jacket in the armhole depth(0.5). Fourthly, the results of appearance evaluation revealed that there was a significant difference in 6 items. In other words, classic jacket was evaluated more appropriate than fitted jacket in such items as back width, back length, back neck depth, chest girth, waist girth and hip girth. And the fitted jacket had a higher value than the classic jacket in shoulder angle item. Fifthly, In the functional evaluation, fitted jacket was evaluated more uncomfortable than classic jacket. And this means that fitted jacket doesn't have a proper ease amount in each part and it has a high armhole depth compared to classic jacket. Therefore, for more comfortable patternmaking of fitted jackets, it would be required a pattern design which reflect men's own shoulder lines and women designers' flexibility that will satisfy both appearance and function.

This study aims to develop sleeve pattern of tailored jacket which shows seamlessly beauty of females in their twenties who have relatively smaller change of body compared people of other ages and has outstanding functional operation. So we selected a pattern of manufacturer who received highest score after evaluating wearing condition of three types of jacket in the industry, whose targets are career women in their twenties and then tested its appearance and functional operation of 6 experimental jackets with armhole depth of B/4 and B/4-1(cm) along with sleeve cap height of A.H/3, A.H/3+1, A.H/3+2. As a result, the pattern which has good result of external appearance evaluation were sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3+2 as well as sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3+1. The pattern of good result for movement adaptation were sleeve with armhole depth of B/4-1 and sleeve cap height of A.H/3 as well as sleeve with armhole depth of B/4 and sleeve cap height of A.H/3. So we could find that the larger is the armhole depth and height of sleeve, the better influence on adaptability of jacket it makes and that the smaller is the armhole depth and height of sleeve, the better influence on movement adaptability of jacket it makes. It has been proved that armhole depth of tailored jacket of females in their twenties doesn't affect significantly on its appearance when designing it but it makes good influence on movement adaptability when experimental clothing has armhole depth of B/4-1and that sleeve cap height of A.H/3 that is 1cm shorter than A.H/3+1 which is used in industry makes good influence on appearance and functional operation.

This study aimed at developing a down jacket prototype that utilized sunlight as an alternative energy source with no air pollution. The jacket is filled with flexible solar panels and has a heat-generating function and LED function. In this study, three smart down jacket prototypes were developed, and the jacket's capabilities were demonstrated through the thermal effect on the performance test. The typical output voltage of the flexible solar panels was 6.4V. By connecting the 2 solar cell modules in series, the final output voltage was 12.8V. A battery charge regulator module was used the KA 7809 (TO-220) of 9V. Three heating pads were to be inserted into the belly of the jacket as direct thermal heating elements, and the LED module was configured, separated by a flash and an indicator. The smart down jacket was designed to prevent damage to the down pack without the individual devices' interfering with the human body's motion. Because this study provides insulation from extreme cold with a purpose, the jacket was tested for heat insulation properties of non-heating, heating on the back, heating on the abdomen, and heating on both the back and abdomen in a sitting posture in a static state. Thermal property analysis results from examining the average skin temperature, core temperature, and the temperature and humidity within clothing showed, that placing a heating element in one place was more effective than distributing the heating elements in different locations. Heating on the back was the most effective for maintaining optimal skin temperature, core temperature, and humidity, whereas heating on the abdomen was not effective for maintaining optimal skin temperature, core temperature, or humidity within clothing because of the gap between the jacket and the body.

This research compared 3 types of jacket pattern design methods for men's wear (age range 25-35) in textbooks. We are to develop research pattern with problem solving based on an analysis of three jacket patterns. The comparative analysis revealed that loose-silhouette slopers A and B scored high in functional evaluation and low in appearance evaluation. However, the tight-silhouette slim-line sloper C received high points in appearance evaluation, but low scores in functional evaluation. All three slopers were evaluated low in the back appearance. The design characteristics of the development jacket sloper were: front width, ($1/10chest{\times}2$)+0.8cm; side width, 1/10 chest+5.5cm; back width, ($1/10chest{\times}2$)+1.5cm; armscye depth, 1/8 chest+11cm; waist back length, 1/2 jacket length+5cm; and hip length, 1/2 (jacket length-waist length)+1cm. The proportions against jacket length were applied to waist length, hip length, and the position of chest/waist pockets. In addition, the back part with low appearance estimation was adjusted as comfortable with the back curve line. Appearance evaluation and 3D clothes modeling system (CLO) showed an overall improvement in the developed jacket sloper when compared to the original jacket slopers.

This research suggested a draft proposal for a smart jacket design, which has applied wearable technologies to provide convenience in daily life. The smart jacket combined with a vest was the casual item for autumn and winter. The heating device was composed of the heating element, battery, controller, electric wire, connector, switch, and charger. A stable electronic conductor fiber of good heating effect with a flexible zigzag form has been selected for the heating element. The lighting device has been made in a way that attaches the LED and its power controller in the same mechanical device. As the result of the wearing test, the heating effect turned out to be effective in the order of: back, both the back and abdomen and only the abdomen. When wearing a smart jacket, the back and abdomen have been selected as favorable body parts for heating. Pockets and hems are selected as the adequate place to attach the LED lighting, and the brightness of LED lighting has turned out to be suitable and useful. Based on the test results, the first draft proposal has attached the heating element only in the back and its controller located in the inside pocket of the vest. In addition, the LED has been attached to the front pocket of the jacket. As to the second draft proposal, heating elements have been placed in the back and the abdomen. Each controller for the heating elements has been placed in the front and inside pocket of vest, and the LED lighting has been attached to the hem of the jacket. The smart jacket combined with a wearable device was assessed by functioning categories. The user showed a high satisfaction in the heating and illuminating function of a smart jacket.
