The purpose of thesis is to concretely determine if there are public nuisances in the learning environment of elementary schools, and to subsequently obtain basic data for planning how to exclude such a nuisance. 6620 elementary school children in Korea have been evaluated to determine standing height, sitting height, sitting thigh length and sitting hip breadth, The results of the analysis of data are as follows: (1) The desks and chairs used by elementary school children are generally high as compared with their physique. Namely, a higher desk than standardized height is present about 60% of the time in case of male students and about 70% of the time in the case of female students. The standardsize desks are in the 30% range in both sexes of a low school year and are about 10% range in both sexes of a high school year. (2) In both sexes the chair size is generally low as compared with their physique. Namely, chairs lower than standardized size are used by about 50% of all the children. Standardized size chairs are about 25% range in low school year and 20% range in high school year in both sexes. (3) It is concluded out that students will be fatigued by being scattered about in a learning posture which causes ill circulation of the blood, depending on the pressure of femur, tetanus of the lumbar vertebrae, side bending of the vertebrae, flat thorax, and other various damages, if chairs are low and desks are high. (4) Standardization of chair and desk size suitable to the physique of children studying as a device for removing a public nuisance in the learning environment is outlined as follows table 6. It will apply to children in the 103cm-152cm range.

The purpose of the present study is to collect basic data which might be made use of in the practical teaching and planning of physical education programs. The study also sets out to discover the patterns of motor ability development in childhood. Out of the childhood population in Seoul City, samples of 449 children (ages between 3 to 12) of both sexes were selected at random. The samples were studied in terms of their motor ability development and the results are summarized as follows: Ability to produce physical movement? 1. It was uncovered that children of both sexes experience the straight development of the lower limbs muscle power and that the age for spurt phenomenon is 5.6 to 6.0 for males and 4.0 to 4.6 for females Male is superior to female in power of the lower limbs muscles. 2. It was discovered that children of both sexes experience the straight-wise development of power in the upper limbs muscles and the difference in power between male and female tends to widen gradually according to chronological transition. 3. It was found that between 3.6 to 4.0 years in males a spurt phenomenon is observed But afterwords a straight development is shown. Male is superior to female in speed. 4. Strength or power of children develops through increasing muscle quantity according to chronolgical transition in parallel with stature or body weight without special training. Ability to continue physical movement 5. It was discovered that it is generally straight-wise development in muscular endurance except spurt phenomenon for males of 4.0 and 4.6 years old and there has been found a wavy type in the case of females of 4.0, 4.6 and 5.6 years old are superior to males in muscular endurance. 6. Children can not continually move stably, because children can not produce strength steadily for a long time, This is due to the slow development of children constive power ability to coordinate physical movement 7. There has been found a wavy type according to chronological transition in flexibility development in the case of males and has been found ceasing phenomenon in the case of females. Male is superior to female in flexibility. 8. It was uncovered that it is straight-wise development in stunt ability in both sexes, and that it decreases individual differences according to chronological transtion. Male is superior to female in stunt ability. 9. It was found out that it is straight-wise development in balance according to chronological transition in both sexes. Female is superior to male at 4.0, 4.6 and 5.6 years old in balance, and it decreases individual differences according to chronological transition, (or "individual differences decrease")? 10. In the motor ability of child-hood develops first coordination, second strength, third power, and fourth muscular endurance. Therefore physical activities in child hood should be satisfied through various free play games.

세단뛰기 발구름 동작을 세개의 발구름과 Hop, Step, Jump의 공중자세로 세분하여 분석한 결과 선수별 발구름, Hop, Step, Jump時의 비행시간 비율은 도약선수가 힘의 고른 분배로 발구름 기복이 적었으며 유연한 궤적이 나타났다. The purpose of this study is to identify the factors impact upon take-off and to promote the technique of triple-jump through that analysis. For the purpose of analysis, triple-jump is divided into three take-offs and three flights-hop, step, jump. The experiment was performed using a 100m sprinter, a 200m-sprinter, a long jumper, a 110m hurdler, and a triple jumper, who are all high school students. The result was as follows 1. The proportion of take-off time and flight time among at hop, step, and jump indicated that jumpers was more regular in proportion even than that of sprinters. This means that the distribution of jumpers' strength among three stages was more balanced than that of sprinters. 2. The more superior skill of a player concurred with the smoother transition of absolute speed of center of gravity, step knee, and free knee, in other words, more streamlined trace of absolute speed during jump. 3. The analysis of ground reaction forces showed that a player with more skillful take-off made higher and sharper zenith meaning more superior muscle power and more effective take-off. 4. The move of center of pressure was more frequently in forward direction and the scope of take-off was wider in plyers with more superior take-off. 5. More effective take-off indicated the propensity of higher ground reaction force and greater power of acceleration. 6. It appeared that a player with superior take-off showed greater perpendicular impact force and greater forward impact force relative to backward impact force.

The purpose of this study is to examine the valuable and reliable measuring methods in cinematographic techniques and it's analysis. To accomplish this purpose of the study it analyzed the films of various patterns of human motion. The obtained results are as follows : 1. The faster photographic speed is, the more accurate sophisticated data can be obtained. However, the coodinating error may be great. Accordingly, it should filter through smoothing technics to decrease coordinating errors. 2. Though the errors of photographic speed correct, it may occur the other errors. Accordingly, it should rephotograph in case of the error of photographic speed. 3. Coordinating of the frames at regular interval influences the law data extremely. Accordingly, it should examine characterisitc of analysing motion in advance in case of framing at regular interval.

The purpose of this thesis is to twst methods of McCloy's General Motor Capacity test if there is practical utility as a diagnosis test through theoretical inspection. This test hase been applied to 263 boys aged Ⅰ4 years old, who were randomly sampled from rural and urban middle schools. The results of the analysis for data are as follows: 1. Coefficient of reliability in McCloy's motor capacity test is more than 0.75. This test is satisfactory as an individual test. 2. Coefficient of objectivity in this test is more than 0.89. This test has a high than standard level in objectivity. 3. In discrimination of this, the coefficient of Sargent jump is 0.77, Iowa Brace test is 0.57, Burpee test is 0.37 and classification index is 0.26. Sub-test items in the classification index are insufficient, accordingly favorable items needsmore study. 4. The difficulty of this test is about 50%. This test is inadequate as a discriminated test motor capacity of men who belong to two poles range 5. Reliability and objectivity of McCloy's motor capacity test is at a sufficient level but validity of this test is not at a sufficient level. If McCloy's motor capacity test has utility as a diagnosis test, this test should be modified to increase sub-test items and adjust the level of difficulty.
