The characteristics of temperature profile around human body with heating life vest at sea were investigated in this paper. Especially, the temperature profile of human body was numerically calculated by finite difference method with Mathcad. The main parameters were seasonal mean sea water temperature, heating amount and heating duration time of heating life vest. In this paper, the boundary layer was composed by the difference matters, and the thermal conductivity was calculated with an adjacent cells using thermal resistance method. It was clarified that the body temperature was kept highly and the risk of death from hypothermia was reduced by wearing heating life vest.

The influence from the increased income and aging society has amplified the interest in the well-being trend and health. People tend to enjoy sports and outdoor life. The development of smart clothing containing heating function to help maintain body temperature has been actively researched after the mid 2000s. However, the domestic study on heating clothing is severely limited. Practical study on designing heating clothing which can be commercialized is needed. The purpose of this study is to develop a commercialized detachable heating vest design through collaboration with a heating vest manufacturer. The results of this study are as follows: 1) Conducted the interview with manufacturer and a demand survey with consumers in order to develop the heating vest design. 2) Developed heating vest design that reflected the wants in the demand survey and sketched the prototype of detachable heating vest. 3) Made a sample of the heating vest and tested the wearability to illustrate the result of this study. Overall, the wearing test result showed high satisfaction for both gender.

By the influence of ageing population, the well-being trend, and the increase of interest in health, people seems to be enjoying sports and outdoor life more. Followed by the change of consumers' life style, the interest in smart clothing grafting scientific technology has increased, and research on this subject is necessary. This study is to develop improved design of band type heating vests by grasping the weak point of currently sold heating vest designed by the manufacturer. Through this process, satisfaction of the consumer and the manufacturer can be increased. The results of this study are as follows: 1) Conducted a demand survey with the manufacturer and wearing evaluation test with the consumer on band type heating vests. 2) Suggested design drafts on band type heating vests for both genders reflecting demand survey results. 3) Conducted consumers' preference survey for design drafts. 4) Made the sample product, and then conducted an evaluation of wearing the actual product. Overall, the wearing test results showed high satisfaction for both genders.

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.
