京都市内の単身者向け住宅の揮発性有機化合物に関する実測調査

An investigation of indoor VOC concentration and a questionnaire survey were carried out in 17 single-room apartments (apartments for single persons) in Kyoto city. The results are: 1) In one apartment, the concentration of TVOC exceeded the provisional objectives set by the Ministry of Health, Labor and Welfare. In 12 apartments, the concentration of HCHO exceeded the guideline of the Ministry. 2) No correlations were found between VOC concentration and apartment age or VOC concentration and years of occupancy. 3) In apartments with high VOC concentration, new furniture made of plywood or two or more chemicals were present. 4) Few residents open windows often but most residents are accustomed to using ventilation fans. 5) Many residents have not taken any measures to cope with the sick-house syndrome, despite such measures being in their own self-interest. 6) It appears that people who are more concerned with the sick-house syndrome have more subjective symptoms of the syndrome

日本人青年の体表面積算出式について(B. 生活科学)

The purpose of this paper is to investigate body surface area of japanese. 45 Japanese young adult subjects were measured. The body surface was divided into the anatomical regions. Measurements were conducted covering the body with small pieces of inelastic tape. It was found the following. 1) Signiticant difference was observed between partial rate of body surface area in relation to sex. There was a significant difference in relation to body forms. 2) Partial rates of body surface area were significant difference from the other measured studies by DuBois. Takahira and Fujimoto・Watanabe. 3) Single component calculation formula of body surface area, Height or Weight, gave higher error by height-weight formula. 4) The surface area calculated by S=100.315W^ H^ was very closer fit to the measured surface area. This formula was widely applicable to sex and body form. Modified DuBois height-weight formula was S=72.18W^ H^

Measurement of heat transfer characteristics by a child manikin with embedded cyclic temperature control

Thermal manikin is an effective tool to study the heat transfer between the human body and the surrounding environment. Combining the heat transfer characteristics with a human-body thermal model enables the detailed analysis of the interaction of the human body and the surrounding thermal environment. Most thermal manikins adopt steady surface temperature control. However, this control method can evaluate the heat transfer coefficient only in a uniform thermal environment while daily thermal environments are non-uniform. In the present study, a theory for cyclic control method is proposed to determine the heat transfer characteristics in a non-uniform environment. A new child-shaped thermal manikin with embedded the cyclic control method is developed. The theory to determine heat transfer characteristics is verified in both uniform and non-uniform thermal environments by using the developed thermal manikin

Assessment of method for measuring clo value using human body – Assessment of method for measuring clo value that assumes human body temperature adjustment

In order to make it possible to measure the clo value in various postures, we are studying the measurement method using the human body. Our previous researches showed that clo value measured with the human body is less than that measured with a “constant temperature control”-type thermal manikin. In our previous experiments, human body changes its skin temperature in response to the amount of clothing or changes in the temperature to maintain heat loss, while a “constant temperature control”-type thermal manikin changes its heat loss in response to the temperature or amount of clothing. Human body reaction is similar to “constant heat dissipation” -type thermal manikin. In order to improve the clo value measurement method using the human body, clo value of same clothing by thermal manikin which changed control method to “constant temperature” and “constant heat dissipation” were measured. Relational expressions of thermal insulation of clothes measured by different control methods were shown
