    The purpose of this study is to investigate the amount of regional evaporation rates of ten male subjects at rest and after walking under different air temperatures in order to determine water transfer properties of clothing materials used in hot environments. The experimental conditions are the same as the previous study, 28, 31, 34 and 37℃ with the relative humidity of 50%. Evaporation rates at the forehead, chest, back, hip, upper arm, forearm, thigh and leg were measured with an evaporimeter.
    The results were summarized as follows:①As the air temperature increased, both the value and the difference among regional evaporation rates increased at rest. The regional evaporation rates on the forehead and extremities were significantly higher than the trunk at 34℃ and 37℃.②The evaporation rates on the forehead, chest and back increased significantly after walking in 34℃ and 37℃ temperatures. ③ As the air temperature increased, a remarkable variation was observed at the regional evaporation rates on the extremities.④The difference between regional evaporation rates and regional sweating rates on the trunk was larger than on the extremities at 37℃.
    From these results, it is predicted the dripping sweat at the trunk increased than at the extremity. Designing clothing, therefore, used in hot environment, it is important to prevent sweat dripping on the trunk through such as wicking of clothing materials.

    Platform providers who have a new role have appeared in inter-firm relationships in distribution systems. This phenomenon is discussed in some literature on inter-firm relationships in distribution systems. However, focusing on the term “platform'', people have different viewpoints on it and the fact remains that it has not been exactly organized yet. The purpose of this paper is that we focus on the term “platform'' and also consider advancement of modern informatization and the inter-firm relationships in distribution systems. This implies that when we focus on the term “platform'' a platform design/model varies based on the platform type we look at. This time, I present the model relevant to supply chain platforms among platform typologies.
