The purpose of this research was to investigate the effects of skin pressure by wearing all-in-one on the rhythm of body temperature such as skin and rectal temperature which play a crucial role in the nocturnal rhythm. Five healthy female were participated in the study as subjects. The experimental clothing was an all-in-one, one of the foun-dation, which is worn for shaping the body. The total experimental periods were 5 days. On the 1st day, subjects did not wear the all-in-one (None), and they wore it for about 12 hours per day from 2nd to 5th day (Wearing1~4). Skin and rectal temperature were measured during the entire experimental days to figure out the rhythm of body temperature during sleep. When subjects wore the all-in-one, the gradients of the forearm and calf skin temperature at the sleep onset were significantly smaller than None It indicated that the rise of extremities` skin temperature was low on theWearing1~4. The decline of rectal temperature in Wearing 1~4 was smaller than None Therefore, the skin pres-sure by all-in-one may cause the temperature of extremities` skin and rectum to change, resulting the fluctuation of the circadian rhythm, finally it could have effects on the rhythm of sleep.

The present study was to (1) develop an ergonomic evaluation system for the systematic analysis of flame-proof clothing (2) comprehensively examine the effectiveness of clothing improvement by using the relationship analysis between clothing design components (D) and ergonomic evaluation measures (E) and (3) prove the usefulness of cost-effectiveness analysis for clothing design optimization. An ergonomic evaluation system for flame-proof clothing was established which consists of four analysis categories (clothing construction, user demographics, work and environment, and usability metrics). By applying the proposed system, the field survey to workers found a comprehensive set of problems on the flame-proof clothing design. The laboratory experiment identified additional design problems using a questionnaire that was developed based on a relationship analysis between D and E. The cost effectiveness analysis is comprised of the preliminary evaluation based on expertise and the in-depth evaluation where the D-E relationship analysis is applied. As a result of the cost effectiveness analysis applied to flame-proof clothing, an optimal design was identified by analyzing costs and qualitative/quantitative effects. It was concluded that the D-E relationship analysis and the cost-effectiveness analysis are useful for comprehensive evaluation and optimization of flame-proof clothing design.

Ergonomic methods have been effectively applied to design and evaluation of functional clothing. The goals of the present study are to: (1) develop an ergonomic evaluation system for the systematic analysis of functional clothing and (2) examine the usefulness of the proposed evaluation system by applying to flame-proof clothing. Based on the survey of literature and the brainstorming of experts in clothing design and ergonomics, factors considered for clothing evaluation were selected, classified, and complemented, resulting in an ergonomic clothing evaluation system consisting of four factor categories (clothing construction, user, work and environment, and user response). Using the proposed system, a field survey and a laboratory experiment were conducted for flame-proof clothing to identify its design problems. The field survey to workers found a comprehensive set of problems on the flame-proof clothing design in terms of pattern, textile, and color. The laboratory experiment identified additional design problems using a questionnaire that was developed based on an analysis on the relationship between clothing design components and ergonomic evaluation measures. The present study showed the ergonomic evaluation system and the relationship analysis of clothing design components and ergonomic evaluation measures are of use to identify design problems of functional clothing in a comprehensive and analytic manner.
