Abstract
The purpose of this study was to investigate the relationship between the Motor Related Physical Fitness Test and the Health Related Physical Fitness Test by two different statistical methods:
(1) Pearson correlation by the sum of Z-scores
(2) Canonical correlation.
The sixty five junior high school students were used for the study with measuring long distance (1000m), sit-up, sit and reach which are considered as the items of the Health Related Physical Fitness Test, and dash (l00m), pull-up, stand broad jump and throwing for distance which are considered as the items of the Motor Related Physical Fitness Test.
The data including the subjects` weight, height and chest circumference were analyzed to find the relation ships among the test items and between the two tests by using S.P.S.S. in Seoul National University computer center.
The results and conclusions were as follows:
1. There are significant relationships among the most of test items, but sit and reach is believed as the most independant item among 7 test items.
2. The relationship between the two tests is r=0.6 by the sum of Z-scores using Pearson correlation.
3. There is only one significant pair of canonical variates between the two tests by using canonical correlation, and pull-up and sit-up have the highest canonical weight of the first canonical variate in each test.
4. The amount of explained variance between the two tests by the sum of Z-scores is greater than the variance explained by the canonical correlation with Hooper`s trace coefficient.
5. There is only one significant pair of canonical variates between the Motor Related Physical fitness Test and antropometric variables such as weight, height and chest circumference, however no significant pair of canonical variates is found with the Health Related Physical Fitness Test at p<0.05.

Abstract
This study has attempted to investigate the changing processes of glucose, protein, electrolyte, and PH. ratio in urine of the athletes and the non-athletes.
The results of the experiment are as follows:
1. The measured amount of glucose in urine was greatly increased among the non-athletes, compared with the athletes. This increase is interpreted as the resell from energy consumption due to motor impulses and time laps.
2. The measured amount of protein in urine was maximally increased in all members right after the game, but decreased after one and half hour.
3. The measured amount of electrolyte(Na+, K+, Ca++, P) was shown somewhat decreased as time goes, but the total change was not statististically significant.
4. PH. in urine showed no change among the athletes, but the nonathletes showd a slight change from 5.0 to 7.6.
5. The proportion of urine was increased in all members after the game. The specific gravity was increased. This increase appears to have resulted from the generation of heat and sweat, but it was decreased after one and half hour limit.

Effects of Physical Training on Water and Electrolyte Metabolism 자연과학편 : 장기간(長期間) 체력단련(體力鍛鍊)이 인체(人體)의 수분(水分) 및 전해질대사(電解質代謝)에 미치는 영향(影響)
Effect of physical training on water and electrolyte metabolism was studied in 17 athletes and 19 non-athletes all of whom were male high school students of 15~19 years of age.
The subjects were required to omit the meal preceding the test and were not allowed to drink for at least tweleve hours before the experiment. Exercise was performed on a treadmill at 5MPH and 1596 grade for 3min.
The subjects were required to empty bladders voluntarily at 20, 40 and 60 min after the exercise and urine flow rate, urinary osmolality, osmolar clearance, free water clearance, urinary excretion of sodium and potassium were measured.
The following results were obtained.
In the resting state, the athletes showed significantly higher urine flow rate, osmolar clearance, urinary sodium and potassium excretion, but lower free water clearance than the non-athletes. Urinary osmolality was not significantly changed.
In the recovery period from the exercise, urine flow rate, osmolar clearance and total osmolar excretion showed significantly decreased values at 20min after the exercise in the athletes, but free water clearance was increased. Non-athletes showed significantly increased urine flow rate but decreased urinary osmolality.
At 60min after exercise, the renal function was significantly different from the resting values, indicating that the recovery from exercise was not complete.

Abstract
This paper attempts to examine the variation of the full speed running curve types in the start block and each block in 100m sprint and analyze the features.
For the purpose the records of eight sprinters of S-Technical High School in Seoul were examined and calculated the average value by the m/sec and were analyzed each of the full speed running curve type.
As a result it came to a conclusion as follows:
1) There sprinters in A group broke their previous records by 0.06 second in the start block and by 0.38 second in the full speed running block according to the data.
It shows up in the full speed running curve that the highest speed and the highest running speed came out in 15m∼30m and in 50m∼60m and also that the speed was rising in the first half and gradually decreased from 70m in the last half
2) Two ones in B group appeared to break their previous records by 0.15 second in the start block and by 0.15 second in the start block and by 0.64 second in the full speed running block.
The full running curve says that it had the highest speed and the highest running speed in 20m∼30m and in 50m∼60m and that it had various speed in the first or last half and had the curve of reduced speed from 70m of the last half.
3) Two ones in C group also showed up in the full speed running curve that they made their records shorten by 0.18 second in the start block and by 0.98 second in the full speed running block and that it had the speed curve to be decreased from 60m and had the tendency to go up in the first half and to fall down suddenly in the last half.
4) One in D group broke his previous record by 0.18 second in the first start block and by 0.54 second in the full speed running block.
The highest speed and the highest full running speed came out in 5m∼10m and in 30m∼50m and its curve showed up as its speed being decreased suddenly.

Abstract
The objective of this study was to develop a golf skill level test and to find out which set of clubs is most important to lowering score for a given individual and a course through computer simulation.
The simulation program was developed by utilizing FORTRAN WATFIV-S and was run on a APPLE personal computer system.
Nam Seong Dae golf course was used as a location of this study.
The players ability of handling each club was simulated by Monte Carlo method using hitting probability data obtained at a practice range for each club.
The following results were obtained:
The resulting handicap (13.8) was slightly lower than the handicap (15) which was calculated by conventional method.
This could be due to the assumptions.
Assuming that the player can handle each club perfectly, i.e., 95% probability to bit a target, study showed that a set of most important clubs for lower if handicap for the player in the course was 8 Iron, Driver, and 5 Iron.
This suggests that the subject should practice 8 Iron, Driver and 5 Iron as an order.
This order of practice would lower the handicap by 0.4 for the subject.
This study demonstrated that Monte Carlo simulation can be an excellent tool in evaluating individual skill level and has a potential to guide the direction of golf practice for lowering handicap.

Abstract
This study attempted to study on kinesthetic method for learning, transfer, and retention of forehand stroke of tennis. This especially focused on some effects of the Kinesthetic learning method for learning forehand stroke skill, transfer of backhand stroke skill and retention of the forehand skill gained of the tennis players.
Subjects of the study were 80 students of 7th grade (first school year of junior high school) sampled from Laboratory middle school, College of Education, Inha University located in Incheon City. The subjects were again grouped in to four, so students for each of the groups in accordance with their pre-test scores in order to make the group mean score equal.
Following were the experimental treatments provided differently to each of the subject groups during the two weeks of experimental period.
Group A. first one week with the eyes open and last one week with the eyes closed.
Group B. frist one week with the eyes closed and last one week with the eyes opened.
Group C. two weeks with the eyes closed.
Group D. two weeks with the eyes opend.
The results of the exprimental treatment were analyzed and compared among the four groups adopting analysis of variance skill.
Upon the statistical analysis, the finding outs of this study were as follows.
First, Group C which practiced forehand stroke with the eyes closed had much more high mean score achieved than Group D which was control group with the eyes opened. However, it was indicated that the significant mean difference between the two groups was statistically negligible.
Second, Group A which had one week with the eyes opened and then one week with the eyes closed, and Group B, one week with the eyes clouted and then one week with the eyes opened had meager mean score achieved than the control group (Group D).
Third, Three of the experimental group; Group A, B, and C had significantly more high mean score achieved in the backhand stroke skill at the end of the experimental treatment than the control group with the eyes opened during the two weeks practice.
It was indicated that the mean differences between the experimental and control groups were statistically very significant.
Lastly, the results of the rotation of forehand stroke skill tested after five days of the experimental treatment, revealed that three of the experimental group namely Group A, B, and C had remarkably less mean score achieved than the control group. The mean difference between the experimental and control groups was statistically very much significant.

Abstract
In the Table Tennis, we can generally divide striking form into Fore-hand Stroke and Back-hand Stroke. We can`t decide that which is the important, but in the exorcise and in the practice game, it is true that the interest degree is high in the Fore-hand stroke while the importance of the Back-hand stroke is neglected, though it is always recognized.
As it is considered that the analysis can he made by comparing the striking forms of Fore-hand and Back hand, so I put an emphasis on the upper limb which is essential in the striking movement of the Table Tennis, exampling 6 male college players who have had over 6 year earlier, and I take the 6 muscles-Deltodeus, Biceps brachii. Triceps brachii, Flexor Carpiulnaris, Brachier adial is Extensor pollicis longus, as the model objects which were used frequently and main movement muscle groups in the terms of articuli monus, articulus humeri cubiti. articuli manus, articulus humeri, cubiti.
As the method of analysis of the muscle movement, Electromyogram surface electrode induction which is necessary to induce as the physiological change and check is taken.
So, as the result of the comparative analysis, I can draw several conclusion as follows;
1. Though the difference is exist in each muscle and in earth hand stroke (Fs. Bs), the duration scope of the overall muscle movement time at the table tennis striking form was 0.47∼0.67 sec. and the preparation movement time was 0.15∼0.31 sec. and the remit movement time was 0.22∼0.4 sec. so it is found that the rest movement time is longer than the preparation movement time.
2. The deltoideus in the Fore-hand stroke is long in the duration time and the rest movement time than that of Back-hand stroke, which indicate meaningful difference (p<0.05)
3. Back-hand stroke has the tendency of longer time-span than that of Fore-hand stroke and especially flexor carpiulnaris presents the longer time gap. (p.0.02∼0.05)
4. While Back-hand stroke the other muscles work more long point except extensor pollicis longus and triceps brachii than fore-hand stroke.
5. The muscle movement order is same except deltoideus and flexor carpiulnaris in the Fore-hand stroke and in the muscle shrink order it begins from the deltoideus in the Fore-hand and from the biceps brachii in the Back-hand.
6. Though the difference of the each muscle Amplitude is exist, the times which the ball impact to the racket and represent the maximum of the electromyogram Amplitude are nearly accorded.
