This study analyzes the wearing and purchasing conditions of outdoor jackets by senior men who are over 50s, and examines product sizes of outdoor jackets in the market. A total of 134 questionnaires and sizing systems (or product size) of 10 outdoor brands were used as analytical data. The results were: a high number of senior men enjoyed hiking as an outdoor activity, with most of them following this activity1-3 times per month and as a preferred personal activity for over 5 years. Most needed outdoor wear suitable for these daily life activities. Outdoor wear satisfaction tends to decrease as people age. The major reason for the dissatisfaction with outdoor wear was price. Senior men aged 50s and 60s emphasize design and color when purchasing outdoor wear; however, men in their 70s considered price a priority. Senior men preferred outdoor brands based on a comfortable fit. An investigation on 10 outdoor brands indicated that they had not designated a specific target customer. A comparison of the product size of outdoor jackets with a similar silhouette indicated some deviations among sizes; however, the age of customers was not considered. The human body tends to shrink in stature and increase in girth as a person ages; consequently, we need to reflect body shape changes and senior's size in outdoor wear.

This study investigates the suitability of outdoor wear among female trekkers in their twenties or thirties and provides data for developing outdoor wear more suitable for young females. Recently climbing has gained popularity as a leisure activity to enjoy the beauty of nature that increases physical and mental stamina. A survey was conducted on 304 female consumers in their twenties and thirties who enjoyed climbing in order to investigate the suitability of outdoor wear among young female consumers. The questionnaire covered the subjects' demographic information, duration and goal of climbing, purchase and suitability of outdoor wear, and preferred design for outdoor wear. As for the yearly situations, when they utilized outdoor wear, the biggest number of respondents chose "autumn" as the season for climbing. Most of the respondents were non-professional trekkers who enjoyed climbing as a hobby or for health. As for the size, the upper garment was 90 and 85 in the order, and the lower garment was 70 and 67 in the order. The pants were the most common item they owned, followed by round T-shirts, windbreaker jackets, zipup T-shirts, and waterproof jackets. They mentioned moisture absorption and dry fabric breathability as the basic functions required of outdoor wear. The subjects displayed a preference for partial details under the design category. They most preferred the hood-type jacket with a detachable stand collar, the sleeve hem with a partial rubber band and velcro strap, a T-shirt with a stand color and zipper, the waist fit with proper room, pants with a partial rubber band waist, and straight silhouette pants.

This study focused on the production and usability evaluation of smart outdoor jackets that are designed to provide convenience to middle-aged people by embedding devices for lighting and location tracing. The results were as follows. 1. Jacket power supplier was a assembled system composed of battery, charger, controller and switch. A solar cell was attached on the upper arm, and a wire type EL on the center line of a raglan sleeve along with a GPS on the left sleeve with a transparent vinyl pocket. The total weight of the jacket embedded with devices was 385-520g. 2. Operation of function, activity, acceptability, safety, convenience for device use, appearance, practical maintenance were selected based on an analysis of evaluation criteria of previous smart wear research. Criteria were narrowed to three major categories of satisfaction, appearance and maintenance. 3. Use satisfaction criterion consisted of wearable device functionality and physical, psychological use convenience. The evaluation indicated actual functionality. EL functions were especially effective and necessary. Convenience of use showed that a smart jacket was thought to be safe and the size was moderate regardless of age and gender. Outer appearance was satisfactory and respondents praised the color. The practical maintenance evaluation indicated that there was no challenge in doing the laundry since the solar battery and GPS were detachable. The practical use of smart outdoor jackets confirmed by fabric that was washable and dried quickly.

This study investigated the thermal insulation of an air-cell pack embedded jacket and down jackets to understand the potential of air-cell pack as a filler for winter outdoor wear. A thermal manikin measured the thermal insulation of the following jackets: HD (heavy down jacket, total weight (Tw) 750g, goose down weight (Dw) 350g), LD (light down jacket, Tw 560g, Dw 140g), AF (air-cell pack embedded jacket, Tw 490g, trunk goose down in LD was replaced to air cell), F (film jacket, Tw 469g, but removed the air in the air-cell pack from the AF), and Control (control jacket, Tw 438g, removed the air-cell pack film from the F). Thermal insulations of each experimental condition were measured in a static standing posture. Total thermal insulations (IT) were 1.29clo (HD), 1.23clo (LD), 1.16clo (AF), 1.20clo (F), and 1.08clo (Control). Body regional thermal insulation was higher in the chest and back than in the abdomen and hip in all conditions. The results suggest that an economical and versatile outdoor jacket with superior thermal insulation will be feasible if the air volume is properly controlled in air-cell pack embedded jackets in consideration of regional different distribution and used in combination with film and down.

The purpose of this study was to analysis of design preference according to age of consumers in order to obtain basic informations which are necessary for the development of designs that can satisfy the needs and desire of Chinese consumers. The style, color, fabric pattern, fabric, image, and shape of clothing were used for design preference variations. The study was implemented by surveying 280 females living in Beijing, China. The results were as follows: 1) There were significant differences in the preference of style of outdoor clothes according to age. Chinese women in the age of twenties and fifties prefer to wear casual clothes. Preference ratio was more than 60% 2) There were significant differences in the preference of color of spring and summer clothes, but there was no difference in the preference of color of autumn and winter clothes. 3) There was a difference in the preference of fabric pattern of outdoor clothes. Generally Chinese women showed 50% of preference for the no patterned outdoor clothes. 4) There were no differences in the preference of fabric materials. Preferred material for spring and summer was cotton fabrics, and that for autumn and winter was woolen fabrics. 5) In the research of the preferred image of outdoor clothes, generally Chinese women showed the most preference for elegance style. Chines women who are in the age of thirties to forties preferred feminine style. However, Chinese women who are in the age of fifties like to choose simple style. 6) There was a significant difference in the preference of length of jacket and skirt, and generally Chinese women preferred to wear medium length of jacket and skirt. There was no difference in the preference of design of collar and shape of pants. However most Chinese women showed preference for tailored collar and straight shaped pants.

There is rising interest in green energy, energy efficient equipment, and products as countries show increased interest in 'Low Carbon and Green Growth'. The cellphone has become one of the essential influences on modem people beyond the meaning itself by the release and the commercialization of the Smartphone. Thus, it considers that the introduction of fashion for cellphones and digital devices to be always on should be a quite natural design attempt for humans to wear clothes at all times. In addition, outdoor activities increase as the population enjoys more sports and leisure time that requires the development of specialized outwear such as the development of a functional jacket. This specialized field is associated with higher value-added businesses. This study made a prototype of a functional jacket equipped with solar cells that established a system of a fashion design that is harmonious with green growth as a plan to measure of fashion design for green growth. The objects of this study are as follow: First, the study seeks a design method for green growth. Second, it makes a prototype to present the improved design method. Third, it presents the establishment of a design system that considers green growth and the concrete measures practical for the system. It established the design system and made the prototype of functional jacket equipped with solar cells, LED, and digital devices as a measure of design for green growth based on the improvement plan of the design that the problems had been supplemented for. Previous studies were mainly about prototypes that attempted to equip mobile digital devices as a study of smart wear; however, this study leaves the issue of power supply for a follow-up study that is different from preceding studies.

This study reports on the development of intelligent clothing using a shape memory alloy (SMA) that forms a still air layer and provides thermal insulation depending on the environment temperature. SMA springs were prepared with Nitinol and have an original length of 6mm and a latent length of 20mm with a response temperature of $24.5^{\circ}C$. Hysteresis was evaluated at a temperature between $0^{\circ}C$ and $40^{\circ}C$. An experimental outdoor jacket that was attached with 30 springs was compared with a commercial jacket in terms of the microclimate temperature, humidity, and comfort properties by human subject tests in the microclimate chamber set at $5{\pm}0.5^{\circ}C$. The results showed that the microclimate temperature of SMA embedded clothing system from the wear trials was higher than the commercial ones during the rest period after exercise, especially on the skin side. In addition the thermal, humidity, and comfort sensations of SMA embedded clothing were better than the commercial ones.

As the interest in leisure and health increases, the domestic outdoor wear industry becomes bigger. The waterproofness of fabrics does not ensure the waterproofness of garments because of the stitch holes during the sewing process even with the seam sealing tapes. Thus the water leakage often becomes a problem during the end use. Still companies use fabrics waterproofness data for garments marketing because they are simple to run the test, less expensive than the whole garment testing, and easy to achieve the quality control. In this study the rain tower system for evaluating the waterproofness of garments has been developed and the waterproofness of the selected waterproof and breathable garments in the market were tested. The rain tower was consisted of rain tower room, rainfall forming system and measurement system. Two different levels of rainfall can be simulated with this system(100l/m²/hr and 450l/m²/hr). Jackets in the market have been tested at two different rainfall conditions. The temperature and humidity data inside jackets didn't provide much information on the waterproofness at severe rainfall condition(450l/m²/hr, 1 hour). However, water leakage was detected on the cotton undershirt inside jacket. 5 out of 8 jackets passed the normal rainfall condition(100l/m²/hr, 30 minutes). The newly developed rain tower system was able to evaluate the waterproofness of the jacket seams. It is recommended the further study on the detailed test conditions for the end use of the waterproof and breathable garments.
