This study was analyzed the validity and the reliability of evaluation norm. which was used in choosing and grading events of the General Motor Ability Test. The General Motor Ability Test has been done for applicants for entrance to the department of physical education, college of education, Pusan National University. The subjects of this study were 433 applicants(men :387, women :46) for three years. They were tested in seven events : 1) 100m Dash, 2) 1500m Run(man), 800m Run (woman), 3) Throwing Hand-Ball, 4) Broad Jump, 5) Chinning(man), Flexed-Arm Hang(woman), 6) Zig-Zag Run, 7) Trunk Flexion. The results could be summerized as follows ; 1. In 100m Dash, 1500m Run, and Throwing Hand-Ball, man's average records were shown normal distribution which was inclined toward low ll grade. Therefore, the interval size of those three events must be regulated to lower. 2. Average records of Broad Jump in man were distributed into high (1) grade. So, the interval size must be adjusted to higher. 3. In Chinning, Zig-Zag Run, ad Trunk Flexion, man's average records were shawn normal distribution, and the interval size was similar to present records. 4. For woman, it was impossible to analyze correctly in all seven events because of the small number of subjects. So, it was for the sake of the reference. 5. The record of applicants for three years were operated to the variable quantity analysis. And the restults were these ; 100m Dash was F=3.0865(p<0.05), Chinning F=3.9309(p<0.05), Broad Jump F=14.7338(p<0.001), Throwing Hand-Ball F=4.9716(p<0.01), and Zig-Zag Run F=6.8297(p<0.001). Then, it was shown statistical meaningful difference in three groups. 6. In investigating the validity in choosing seven events, it was concluded that the events have been chosen reasonably. Because all events except for 100m Dash, and Zig-Zag Run in man were independent. From the analysis of the General Motor Ability Test, we could realized the necessity of regulating the standard and the interval size in several events. Then, we proposed the new evaluation norm which was suitable to present situation.

This study is to present more effective starting skills through analysis of kinematic characteristics of starting motions in 300m Time Trials of Inline Skating. To achieve the goal, 6 athletes, 3 in the national team and 3 in business teams were chosen and their starting motions were examined with three-dimensional image analyses. The results of analyses in regard of speed of the body center and linear velocity of articulations of lower limbs by sections of starting motions are as follows: 1) Acceleration in the starting section is determined by the speed and the position of bodily center at the moment of leaving the ground not by the aerial movements. In case of the central position, though it is effective to reduce the air resistance by lowering the upper part of the body maximumly, it is reasonable to accelerate by raising the upper part of the body to some degree for the running posture at the lower speed in the starting section. At the lower speed in the starting section, since the push-off motions are made with the front part of skates at a point, not while gliding, the angle in the articulations of lower limbs is bigger. This shows that the faster changes from the running posture to the gliding skills is made, the more effective motions can be made. 2) At the moment of starting, acceleration by reducing the angles of knees to increase safety on the ground is reasonable, but wheels should touch more with the ground to minimize the impact and friction of skates. In the starting section, it is efficient to minimize the period of time in touching the ground. For this, it is necessary to train for taking motions without slippage while touching the ground. 3) While 3 athletes in business teams kicked the ground as running right after the starting, the others in the national team slid on the ground. As the number of steps increased, the movable speed changed quickly. Thus the movable speed of athletes in the national team indicated big differences in two to three steps. If these factors are well supported, the push-away starting method might be better than the running starting method in terms of improvement of records.

The Stem and the Radix of Parthenocissus tricuspidate (Vitaceae) have been used in arthrities laryngitis, jundice, neuralgia, renal insufficiency in folk remedies. In order to investigate the effects of their water extractums. on kidney function of normal and acute renal failure rats induced by the single s.c. injection of 2mg/kg HgCl_2, urinary volume, excretion rates of Na, K, Cl, serum chemical parameters were measured. The radix ex. 1.0g/kg showed significant diuretic action at 1-2hr. after administration. In renal failure group, the stem rather than the radix increase urin volume, electrolyte excretion at 2-5hr. after administration compared with 4-5hr. of furosemide and they didn't affect the level of serum parameters.

The purpose of this study is to investigate the effects of Adlerian Group Counseling Program which was based on individual psychology on inferiority feelings and academic self-efficacy of the academic high school students. For this study, the following hypotheses were established. First, there would be significant decrease in inferiority symptoms including three subordinate factors (sensitiveness, negativeness, retreat) for high school students after the treatment. Second, there would be significant increase in academic self-efficacy including three subordinate factors (self-confidence, self-regulatory efficacy, task difficulty preference) for high school students after the treatment. The subjects of this study were 27 first grade students of academic high school in Busan. 12 students were assigned to an experimental group and 15 were assigned to a control group. The study progressed through three stages : pre-test, experimental intervention (participation in the program by the experimental group), post-test. The experimental group participated in 15 sessions of 50 minutes each over six months. Inferiority Symptom scale (Yim, Gie-Hong) and Academic Self-efficacy scale (Kim Ah-yeong, Park In-yeong) were administrated in both experimental and control group.The results from this study were as follows; First, Adlerian Group Counseling Program significantly decreased the total scores in inferiority symptoms and the each score in three subordinate factors (sensitiveness, negativeness, retreat) for the experimental group subjects. Second, Adlerian Group Counseling Program significantly increased the total scores in the academic self-efficacy and the each score in three subordinate factors (self-confidence, self- regulatory efficacy, task difficulty preference) for the experimental group subjects. Based on the above results, it can be concluded that Adlerian Group Counseling Program is very effective in helping the high school students reduce the level of inferiority symptoms and elevate the level of their academic self-efficacy. Therefore, Adlerian Group Counseling Program can be strongly suggested as a useful means for high school students' self-growth and improvement for their fruitful school lives.
