This study was designed to investigate whether or not the areas of the human body most sensitive to itch stimuli are identical with the body parts least sensitive to tactual discrimination, a hypothesis which arouse from our previous studies of itching. Subjects were 12 college students (six males and six females). The itching was induced by grated Japanese yam. The body areas were the upper arm (with large two-point thresholds), the lower leg (with intermediate two-point thresholds), and the middle finger (with small two-point thresholds). An experimental session consisted of a stimulus-application period (200 s), and a post-application period (600 s) during which the itching increases markedly. (After wiping off the grated yam, itching is increased because of the needle-crystals of calcium oxalate contained in the yam peel which penetrate slightly into the skin in the process of wiping.) Self-ratings on itching and the volume of dermal blood flow were recorded during two periods. The results support our hypothesis and suggest that tactile sensation has some interaction with itching.

This paper aims to grasp and evaluate the present condition of the main streets in central Taipei City that was once under the occupation of japan. At frrst,the way of utilization, the structure and so on of each street are investigated by the field surveys. Then, the streets are evaluated from the viewpoints of safety,smoothness,scenery,location etc. based on japanese and Taiwanese students' consciousness. As the results, it is made clear that japanese students tend to regard "location" as more important factor and Taiwanese students tend to regard "safety" as more important factor in the evaluation of the streets.
