It's been over thirty years since we set the divided group life system into the dorm. During this period, as the Information Technology develops, many things have changed and sometimes students do undesirable actions that are beyond our imagination. To capture the situations in the dorm, we conducted a questionnaire survey on their daily life. This paper shows the following things: how they spend their daily life, how they build their connections with other students, what they think about facilities of the dorm and so on.

The purpose of this study was to measure blood pressure (SBP, DBP), heart rate (HR) and power spectrum (LF, HF) during four types of isometric handgrip exercises (IHG) with the different intensity and duration of time, to observe the function of the autonomic nervous system, and to clarify the response patterns induced to intensity and duration time for the assessment of hypertension. Eighteen male subjects aged 20 years old cooperated as volunteers, and performed four kinds of IHGs on one day for each subject. Experiment (Exp)ⅠandⅡconsisted of five intensities of IHG set for 20, 30, 40, 50 and 60 percent of maximal voluntary contraction (% MVC). ExpⅠgot intermittent (Int) loading contraction, the subjects keep gripping for ten seconds each % MVC with sufficient rest between IHG trials. ExpⅡ(continuous; Cont) got the same procedure as ExpⅠ, but no rest between trials that was done incrementaly. ExpⅠandⅡof IHG both tried from 20% MVC to 60% MVC. ExpⅢ(steady contraction; Sted, 40% MVC) got contraction keeping for forty seconds, and ExpⅣ(Sted, 30% MVC) kept the continuous grip for two minutes. Subjects accomplished all Exps in sitting on a chair. The load level (%) was checked by a picture on a personal computer in front of the subject by itself. During the IHG, arterial SBP, DBP, HR were continuously measured, and calculated LF and HF from the saved HR data with heart rate variability (HRV) software after these measurements. During IHG, the stronger of intensities or the longer of duration, the higher of SBP, DBP and HR were showed. Those differences were remarkably indicated on the Sted (Cont) than on the Imt trial. The pressor response of Cont IHG significantly correlated to SBP/DBP increase in Sted IHG, those makers during the Int IHG didn’t correlate significantly though. HF and LF power revealed enhancement of activity on the autonomic nerves induced to increase of hardness during IHG. According to above results, continuous (Cont) and/or steady (Sted) loadings seemed to be effective to evaluate hypertensive possibility in future much more feasible and validly than Imt loading so far the loading under 60% MVC.

It is pointed out that group learning can foster learners' sociability and enhance their learning motivation. In physical education classes, these effects can be expected by setting an appropriate tasks to carry out in a group. In the case of judo lessons, Maemawariukemi is more technically difficult than Usiroukemi and Yokoukemi. Therefore, the speed to acquire the skill, Maemawariukemi, varies from individual to individual. The purpose of this study is to examine the effects of group learning as an active learning method to learn Maemawariukemi.
