The purpose of this study was to find out the effects of a 12-week elastic band exercise on health-related fitness and blood lipids in 4th grade elementary male students. Sixteen subjects were participated in this study from one elementary school in Busan. Participants were randomly allocated to experimental group(n=8) and control group(n=8). Experimental group conducted 50 minutes of elastic band exercise three days a week with 11 to 15 Rating of Perceived Exertion (RPE) for 12 weeks, and the control group continued their normal life. In experimental group, lean body mass, percent body fat, cardiovascular endurance, and muscular endurance were all significantly improved after the program, but muscle strength, flexibility were not changed. While in control group, percent body fat and muscular endurance were significantly improved. There were significant interaction effects (group by time)of cardiovascular endurance, and muscular endurance between groups after the program. Group analyses showed that there were no significant difference in all blood lipids (T-C, TG, HDL-C and LDL-C) within group and between groups after program. These results indicate that elastic band exercise is effective to improving cardiovascular endurance, and muscular endurance in normal elementary male students. However, long-term follow up studies are necessary to clarify moderate exercise intensity of the elastic band exercise for normal elementary male students.

This study aims at suggesting a proper level of tax burden in Korea. To this end, I conducted an extensive literature survey on the theories of tax burden analysis on the determinants of tax burden ratio against GNP for a number of selected countries. The most important factor that affects the tax burden ratio turned out to be the level of national income. Based on the overall result of theoretical analysis findings, I propose the following policy suggestions with regard to the desirable directions of tax system and tax policy in korea : First, it is desirable that expenditures on social welfare should be increased and income redistribution function of tax system should be enhanced. Second, it is necessary that the burden of income and property taxes should be increased while the burden of indirect taxes decreased in order to achieve a more equitable structure of tax burdens. In particular, an amendment of tax system is called for to solve the problem of inequitable tax burden among different occupations and income groups.
