Chae, Hong Wun : (Dept. Physical Education, Kongju Teachers College, Choongnam, Korea). A study on Anlysis of Operation in Volley Ball Game. Ref. Sci. Education, Inst. Sci. Educat. Kongju Teachers Coll. 1 :17-50 1968 : The following analysis of operation system has been tried through theory of compr ehensive instruction and by projecting concret and various new operations for guiding technigues in volley ball game. Before summarizing system of instruction dynamic principle about analysis of offensive hitting point and movement of intercepting angle on defensing should be taken into consideration. It is one of the important factors for successful operation to raise hitting point for offensing and to control changeable ball freely and to make reasonable defence system and blocking against offence. From this point of view a study of correlation between hitting point and intercepting angle plays an important role as the key to successful operation. According to hitting point coefficient by a Japanese whose name is Maeta Totosi, that is stature+Sargent jump+average length of arms of male (or female), and individual hitting point variable table and that of intercepting angle variable have been figured up in 1/100 reduced draqing by principle of angle movement. The result of th study draw conclusion that the hitting of angle movement. The result of the study draws conclusion that the hitting point should be more than minimum 248.4 to make a successful offence from the net to the endline, and so players should be tall enough with high Sargent jump, and that cutting-off angle by blocking shows relating changeable aspect between hitting point and blocking distance, that is to say the nearer the blocking distance is the wider the angle movement will be, and the further it is, the narrower it will be according to the number of players for blocking, i.e, characteristics and width of blocking, and the more the number of players for blocking is, the width cutting-off angle will be. Under this fundamental law offensive must be made good use of with constant scientific operation. This paper is about analizing and making various operation of the have composed of fiv attackers with the Center of Setter, and trying to have system of instruction, the out line of whose contents is about projecting analysis on each applicable operation as the following. 1. Offensive technique; (1) Three-stage operation: when setter No3, comes to be Cattacker, R-attacker, R-Backer, C-Backer, L-Backer, and L-attacker. (2) Two-stage operation: for direct offence against tossing towards the net in 1,3,2 system or 4.2 systems. (3) Feint operation: for feint at two or three group blocking. (4) Stop out operation: for touch out at two or three players blocking (5) Operation on difference in time movement for various differences intime at three or two-stage offence. 2. Defensive techniques: (1) Defensive operation at serve receive for defence in 1,3,2 or 4.2 systems. (2) Defensive operation at spike receive: for defence and each variety of intercepting angle at one, two or three players, blocking. (3) Defensive operation at Feint receiver: for defence of each Feint space at one, two or three plyers' blocking 3. Operation: the general principle of team making and a study of instructinf plan and analysis of applicable operation on Substitution and time ou have been mentioned.

In order to study the postures of Korean students, 4,448 students who lives in urban and rural community were participated as subjects and examined by using New York State Posture Rating Test Method with taking photographs. The results were subdivied into postures of body parts, total posture score, leg types, and lateral deviation and analysed as follows. 1. Postures of body parts 1) Head Tilt For elementary and middle school students, the cases of tilted head were shown more frequently in urban than rural and the ratio of the case of the tilted head was increased as grade was higher. On the other hand, high school studends had the opposite tendency. 2) Uneven Shoulder Height For elementary school childs, higher grades had better condition than lower grades, however, for high school students, those in urban had more cases of uneven shoulder than those in rural and girls showed more deviations than boys. 3) Scoliosis Rural childs had more cases of scoliosis than urban childs, but there were no differences of middle and high school students. 4) Uneven Hip Height Urban and rural childs showed some cases of uneven hip which belonged to normal ranges. Middle and high school studedns werw nearly perfect in the hip height, therefore the condition seems to change as they grow older. 5) Pronated Ankles For this part, those in rural showed better conditions than those in ruban in all age groups and, especially high school third grade students were more satisfactory in rural than urban(84% vs 50%) 6) Forward Head Elementary and middle school students appeared to be satisfactory regardless of age, sex and district, however 32% of high school girl students had forward head. 7) Round Shoulders Many students had round shoulders and some of them revealed severe conditions, There were large differences between urban and rural students. 8) Trunk Hyperextension Generally, girls showed better conditions than boys in trunk posture and, for high school boy students, conditions were differed according to their grades. 9) Sagging Abdomen More cases of sagging abdomen were revealed in ruban that rural for elementary girl students(30% vs 14%). For middle and high school students, there were differences between sex, boys showing more cases than girls in middle school and girls in high school. 10) Lordosis There were differences between urban and rural for elementary childs and high school boy students, however no differences were detected in other groups. Mean degrees of lordosis had a tendency of increasing as the age grew. 2. Total Posture Score For elementary childs, both boys and girls showed differences between urban and rural(75.95 vs 70.73, 75.16 vs 82.42), and, in rural girls seems to be more satisfactory than boys in comparison between boys and girls(p<. 001). In middle school group, rural students appeared to be significantly(p<.05) better than urban students for both sex(83.88 vs 81.93, 75.93 vs 75.02) and the result was same for the high school group(86.52 vs 84.03, 80.07 vs 78.10) 3. Leg types For elementary childs, girls revealed more cases of bowlegs and knock-knee than boys(6% vs 8.2%, 20.5% vs 30.3%). In high school group, the girls in rural showed more cases of bowlegs than those in urban(29.7% vs 13.0%) and, the knokc-knee, the result was opposite(19.3% vs 28.4%). 4. Lateral deviation 1) Head Tilt In elementary group, 11% of boys and 6.3% of girls had lateral deviation and, for high school students, 3.6% of boys and 5.4% of girls showed the deviations revealing girls had more cases of deviation than boys. 2) Uneven Shoulder Height 1.8% of elementary boys and 0.5% of girls had uneven shoulder and totally 1.5% of high school students showed uneven shoulder height. 3) Scoliosis 15.5% and 17.4% of elementary boys and 21.6% and 20.7% of girls deviated to right and left respectively. Urban students showed general trends to leftward deviation while rural students showed rightward deviation. 4) Uneven Hip Height In this part of posture, they showed good conditions in all age, sex, and district.

It is well recognized that exercise training induces the changes of %body fat (%BF) and the fat cell proliferation (FCP) in growing animal and human, but the role of training intensity in the %BF and FCP was not intensively investigated. Thus, the effects of high (HT; n=9) and low (LT; n=9) exercise training intensity with the same training volume were examined on %BF and FCP in growing male rats. Sedentary (CON; n=10) male rats were used as controls. After 8-weeks exercise training, the carcass was ground by using the blender, and then %BF was measured by the lipid extraction technique of Folchs method. Total body water and Fat-free dry mass was determined. The fat cell proliferation was evaluated from total cell number of retroperitoneal fat pad. -------------------------------------------------- (n) CON LT HT (10) (9) (9) -------------------------------------------------- % BF 13.78+1.03 4.44+0.35* 5.65+0.80* % FFM 5.42+0.58 1.42+0.12* 1.86+0.28* % H2O 61.36+1.22 67.94+1.28* 67.53+0.51* Total cell 7593*10(3) 5019*10(3) 4359*10(3) number +650*10(3) +646*10(3)* +569*10(3)* in retro fat pad -------------------------------------------------- Values are means +SE. *: Significantly different from CON. Our results indicated that training intensities did not affect %BF and FCP of growing male rats unlike the volume of exercise training.

蔡鴻遠 慶北大學校 體育科學硏究所 1987 체육과학연구지 Vol.3 No.-

The main purpose of this study is to analyze the effects of plyometric "Super quality Training: SQT" programme for improving leg power performance of volley ball players. 25 male players were randomly selected out of the volleyball players in KPU and its attached high school. The experiment was focussed on jumping height, speed and repetitive jumping speed in the take-off in box drill dropping performance. Various articles have reported that, during the take-off jump, exterior muscle at the bagnning fulfill both yielding work(the phase of amortization) and later overcoming work(phase of active take-off). Therefore, in the experiment the subjects were required to keep their both legs upward after the plumb-line jump from the box 50∼90㎝ meter height. The landing area was conditioned with thin elastic sponge rubber(amortization phase). During the 8 weeks of experiment, the training was regularly enforced once per day, 3 on 4 times frequence a week, The data statistically obtained were analyzed and compared logitudinal analysis, the results of which are as follows: ① Jumping height: The performance of exp. subjects was greatly improved after experiment. The increase of jumping height in the exp. subjects was 3.8㎝∼7.1㎝(8.3%∼15.3%). The values of all items were statistically significant of 0.001 level. ② Jumping speed: The performance of exp. subjects was greatly improved after experiment. The increase of jumping speed in the exp. subjects was 2㎳∼450㎳(3.9%∼30.6%). The values of all items were statistically significant at 0.05 or 0.001 level. ③ Repetitive jumping speed: The performance of exp. subjects was greatly improved after experiment. The increase of repetitive jumping speed in exp. subjects was 500㎳∼5010㎳(8.6%∼19.6%). The values of all items were statistically at 0.01 or 0.001 level.

The objective of this research is to analyze the actual state of juvenile posture formation and defects resulting from the environmental differences between urban and rural areas, and further to suggest the concrete data for the practical posture guidance. Boy and girl students from K junior and D girls' junior high schools of Taegu City and H junior high school of Kyungpook Province are selected as purposive samples. Thus 291 boys and 321 girls from urban and 260 boys and 270 girls from rural areas are sampled to be a total of 1142 boys and girls. As the methods of test, New York State posture Test(NYSPT), bowleg(0-type leg) and knock-knee(x-type leg) tests are used with the aid of photograph. Their results are as follows. 1. The final scores and percentages of NYSPT evaluation of boy students in urban and rural areas are 57.2(58%) and 58.0(60%), respectively, and their achievement scores are 6.3 and 6.8 within normal state. The comparison between urban and scores shows that rural students are in more correct posture with 1% level of significance than urban students. This is statistically meaningful(p<0.01). 2. The final scores and percentages of HYSPT evaluation of girl students i% urban and areas are 59.0(69%) and 60.0(69.3%), respectively, and their achievement scores are 7.0 and 7.2 within normal state. The comparison between urban and rural scores shows statistically meaningless with 5% level of significance(p<0.05). 3. The NYSPT evaluation scores of posture formation between boys and girls in both urban and rural areas shows that girls are in more correct posture than boys with average differences of 3.05 and 2.05, respectively. 4. The NYSPT evaluation according to bodily parts are as follows : In the lateral head deviation, average angles of urban and rural boys are 7.39° and 6.02°, whereas average angles of girls are 6.52° and 6.98°, respectively. All of these are inclined a little to the abnormal ragne. In the low shoulder, average angles of urban and rural boys are 1.44° and 1.33°, and also 1.46° and 1.33° to girls, respectively. All of these are within the normal range. In the scoliosis, the percentage of urban students are higher than the one of rural students. The students in the severe scoliosis are 0.73%%, 8 out of 1142 students. 5. In the average scores about the types of legs, distribution percentages and indices of bowlegs are 27.2%, 3.85 in the urban and 43.2%, 3.75 in the rural boys, respectively. In the girls, they are 20.6%, 3.89 and 29.6%, 3.90, respectively. This shows bowleg is more dominant to the rural students. Distribution percentages and indices of knock-knees are 15.5%, 4.57 and 12.7%, 3.95, respectively, in the urban and rural boys. In the girls, they are 7.17%, 4.0 and 0%, 0 respectively. This shows knock-knee is more dominant to the urban students.
