The purpose of this study is to investigate the effects of daily physical activity on the endurance ability and the obesity index in a boy with down's syndrome. We examined the subject's obesity index and he was mildly obese(Rohrer-index:161.4, body fat:24.8%). The amount of daily physical activity and its intensity(light,moderate and vigorous) was estimated by a pedometer(Lifecorder) two times during the school term and during the summer vacation. There were significant differences between the school term period and the summer vacation period in steps/day(9347±1561 vs 7086±2517, p<0.001), light activity(min/day)(70.7±10.3 vs 52.6±13.0 p<0.001)and vigorous activity(min/day)(6.4±2.9 vs 2.7±1.6 p<0.001). There was no significant difference in moderate activity(min/day). We conducted walking tests before and after the summer vacation to examine the walking speed at a heart rate of 132 beats/min(aerobics with smile), which we used as the index of endurance ability. His walking speed changeed from 80.8m/min(pre-summer vacation) to 56.1m/min(post-summer vacation) showing a decline in endurance ability. This suggests that the decrease in daily physical activity during summer vacation influenced the decline in endurance ability of the subject.

The seasonal variations of the water quality and the tidal flow in Toyama Bay were observed by using Conductivity Temperature Depth(CTD) and Acoustic Dopplar Current Profiler(ADCP). Tsushima warm current(TWC) intrudes about 100m in depth in Toyama Bay. The Japanese sea proper water is observed under 400m in depth; the salinity is from 34.1 to 34.2 and the potential temperature is around 0℃. The flow field in Toyama Bay is observed by ADCP system in the summer and the winter time.

Roh Moo-hyun, a candidate for the Millennium Democratic Party, became President against Lee Hoi-chang, candidate for the Grand National Party, after the presidential election held on December 19th, 2002. Before the 15th president Kim Dae-jung, who was from the Honam region-from Pak Chung-hee in the 1960s up to the 14th president Kim Yong-sam, all the presidents were from the Yongnam region. And this had led people in the Honam region into disadvantageous situations in terms both of economy and politics. What is noticeable from the 16th presidential election, however, is the fact that Roh Moo-hyung is from the Yongnam region, unlike the previous ones, and that therefore, it is assumed that the electoral culture in South Korea, including "Regional Emotion" seem to have changed a great deal. In this paper, the author points out the characteristic features of the 16th presidential election in South Korea in terms of why that happened and of the electoral culture, by contrasting the 16th election with the previous ones.
