To be able to work safely and efficiency, the Threshold Limit Values (TLV) for work in the heat are widely used. Since these TLV are only applicable to workers in regular clothing, TLV should be adjusted when applied to the asbestos removal workers who wear extra impermeable protective clothing. Although abbreviated guidelines for heat stress exposure have been proposed, literature advocating their use in the asbestos removal industry is limited. Therefore, we planed a survey to evaluate the workload of asbestos abatement workers in summer, and an experiment with climatic chambers to evaluate the effects of resting in a cool environment between work periods. From these studies, we got following conclusions. There is a high risk of suffering from heat illness by asbestos abatement work in summer in Japan. It is proposed to create a cool room inside the workplace of asbestos abatement work to reduce thermal stress.

In this letter, we propose a dual autostereoscopic display platform employing a natural interaction method, which will be useful for sharing visual data with users. To provide 3D visualization of a model to users who collaborate with each other, a beamsplitter is used with a pair of autostereoscopic displays, providing a visual illusion of a floating 3D image. To interact with the virtual object, we track the user's hands with a depth camera. The gesture recognition technique we use operates without any initialization process, such as specific poses or gestures, and supports several commands to control virtual objects by gesture recognition. Experiment results show that our system performs well in visualizing 3D models in real-time and handling them under unconstrained conditions, such as complicated backgrounds or a user wearing short sleeves.

견과 합성 섬유의 단점을 서로 보완하여 새로운 성능을 가지는 신소재를 개발하기 위하여 견사와 나이론사와의 복합사를 제조(이하 S/N 복합사)하고 이들 복합사 스타킹에 대하여 품질을 평가한 결과는 다음과 같다. 1. SEM으로 S/N 복합사로 제편한 스타킹을 관찰한 결과 나이론사는 매끈하게 보이는 반면 견사는 약간 불규칙하게 나타나서 쉽게 판별할 수 있었으며 견사와 나이론사가 서로 잘 포합된 부분과 견사끼리 합쳐진 부분이 발견되었다. 2. S/N 복합사 스타킹의 흡수속도는 나이론 스타킹에 비하여 4~8배 높았고 무연보다 가연할 경우가 높았다. 흡수율에 있어서도 S/N 복합사 스타킹이 나이론 스타킹에 비하여 3배 이상 높았다. 3. 수축율을 보면 상온수에서는 나이론 스타킹과 S/N 스타킹간에 큰 차이는 없었으나 비등수에서는 나이론보다 S/N 스타킹편이 약간 많이 수축되었다. 한편 스타킹간의 수축율과 수축탄성율은 큰 차이는 없었다. 4. S/N 복합사 스타킹의 착용시험 결과 보온성, 촉감은 나이론 스타킹보다 우수하였으나 수축성은 나이론 스타킹에 미치지 못하였다. 그러나 종합적인 호감도는 나이론 스타킹에 비하여 우수한 것으로 나타났다.

For the purpose of examining the relationship of physiological and subjective responses to different exercise intensities and varied types of sportswear material, under environmental condition $20{\pm}1^{\circ}C$ $50{\pm}3%$RH, five men who wear four different kinds of sportswear which have same clothing cover area. The subjects exercised for 20 min with a 20 min pre-exercise rest period and another 20 min post-exercise recovery period. Throughout the 60 min. duration, we monitored the local skin temperature, rectal temperature, clothing microclimate and subjective sensation. The mean skin temperature was recorded to range from $33.5{\sim}34.1^{\circ}C$ for the entire duration of the experiment with the highest temperature observed at the 7th min after starting the exercise. During the exercise intensity at THR 20, the lowest recorded temperature was at the 5th min of the recovery time and stabilized at the 10th min. However, in the exercise intensity condition at THR 70, the temperature declined steadily until the end of the experiment. With regard to clothing materials, cotton 100% and Polyester/Cotton blended fabrics knit(35/65) was $0.5{\sim}0.7^{\circ}C$ maintained lower than Polyester 100% and polyester/Cotton blended woven fabrics (65/35). In the case of the rectal temperature at THR 70 in case of PET 100%, Polyester/Cotton blended woven fabrics (35/65) was higher $0.2{\sim}0.5^{\circ}C$ than other sportswear throughout the duration of the experiment.
