The purpose of this study is to search the life style and participation motive of participants in water skiing according to the trait of population statistics and identify the influence of life style and participation motive of those on reusing it. For this purpose, the study implemented independent t-test, one-way ANOVA, and multiple regression analysis and thus it draw the following conclusions. First, There are differences among the contents of life style according to the trait of population statistics. When consulting those results about life style in the concrete, there are differences according to their age in family based style. There are differences according to their age in leasure culture-pursuing style. There are differences according to their age in individualistic style. There are differences according to their age in conservative type. Second, there are differences among the contents of participation motive according to the trait of population statistics. When consulting those results about participation motive in the concrete, there are differences according to their gender in self development. There are differences according to their gender and age in social fellowship oriented motive. There are differences according to their age in family oriented motive. There are differences according to their age in good use of leisure time. Third, there is influence of life style and participation motive of participants in water-skiing on their reuse. When consulting the results in the concrete, the participation motive has positive influence on reusing it. And also leisure culture-pursuing style, among the sub-variables, has positive influence on reuse.

This study was performed to present the exercise intensity in actual field using POLAR heart rate measurement equipment by predicting the heart-rate and energy consumption in different part of disabled dance sports, 16 athletes(8 men, 8 women) from Dance Sports Research Center located in Seoul who have spinal cord injury were the object of this study, Active professional dancers were selected to maintain the level of identity of this study and after the experiment, health checkup of the athletes were implemented by qualified medical research centers. Then we earned this conclusion : Heart rate was higher in men than women in part of dance sport, physical exercise was higher in women than men. Tango and jive showed higher exercise intensity in energy consumption, on the other hand, rumba showed low exercise intensity, In this study, because experiment was performed only three part of dance sports, we think expanding part of dance sports and considering variety of age, physical characteristic for versatile study.

The forest fire can cause serious damage to overhead conductor. In consequence, properties of overhead conductor will be changed. No systematic study on the changes of conductor's property was carried out. Therefore, this study was focused on the changes of conductor's temperture, tensile strength when they were exposed to fire.

The forest fire can cause serious damage to overhead conductor. In consequence, properties of overhead conductor will be changed. Tensile strength test was the only method to clarify the abnormality of conductor is measured for life prediction of overhead conductor. But, this method needs very much time and cost because tensile strength is breakdown test. Therefore, the authors reserached into the non-destructive life prediction method by changes of hardness conductor surface. We verfied that the changes of hardness is guide similar with those of tensile strength.

Tensile strengh is used for life prediction of overhead conductor damaged by forest fire. But, this method needs very much time and cost because tensile strength is breakdown test. Therefore, the different way of testing method is needed to investigate the abnormality and predict the residual life time of overhead conductor damaged by forest fire. This study was performed to develop the new test method to predict the lifetime of fire damaged conductor in terms of reserch on strength, hardness and sag.
