On the Floor Exercises of man contestants of the World Cup competition held in 1979 and 1980, the performance contents of winners (from 1st to 12th) were analyzed as follows; 1. The average scores were 9.542 in 1979 and 9.654 in 1980. 2. The degree of difficulty marked 4.7C, 3.5B, 9.4A in 1979 and 4.7C, 2.4B, 9.8A in 1980. The numbers of the elements of the additional points were 1.6 and 2.7 respectively, resulting superior qualiy in 1980. 3. On 1979 and 1980, 9 contestants (39.1%) performed Moon Somersault as their starting technique of tumbling and 6(26.1%) Backwards Double Somesault (style A) 9 contestants (39.1%) performed Backwards Double Somersault(A style) as the ending technique and 11(47.8%) Backwards Somersault with 2 Turns. 4. The new techniques with much difficulty were Backwards Double Somersault with 2 Truns and Round off →½ turn to Forwards Double Somersault. 5. The contents of the tumbling technique were as follow; ⅰ) Round-off marked 83.3% as the starting technique. ⅱ) Among 12 contestants, 10 performed 4 kind of tumbling techniques and the other 2 performed 3. ⅲ) The average of running paces was 1.84.

The results of this study analysis on performance tendencies in Parallel Bars are summarized as follows: (1) In the selection of performance techiques, the techniques, such as Backward Salto, Forward-swing Half-twist, Stable Cut, Diamidov, Cast, ect. are forming a main-stream of perfomance techniques in the parallel bars. (2) In the selection tendencies of performance techniques by style, Push-up style takes almost half of all styles. In order to prepare for required performance techniques, those in four styles must be throughly and evenly familiarized. (3) The selection patterns of performance techniques by degree of difficulty and easiness, are indicated as follows: In one style of techniques, an average number of kinds of such difficulty and easiness for each performer are represented as C=5.5, B=4, A=2 for performers who won in the international competition and as C=4.5, B=4, A=4.3 for performers who won in the Korea representation competition.

Moon Somersault에 關한 硏究

As follows a synopsis of the study on Moon Somersault. 1. Moon Somersault can be classified into various types: (A). The type that the contestant is to twist his body his body more than 360 degrees at the first somersault of the double somersault and perform a simple somersault at the second somersault. (B). The type that the contestant is to perform a simple somersault at the first of the double somersault and twist his body more than 360 degrees at the second somersault. (C). The type that the contestant is to twist his body more than 180 degrees both at the first and the second somersault of the double somersault. 2. Techniques of Moon Somersault in the horizontal bar, the rings, and the floor are the applications to the three types mentioned above. And the techniques of New Moon Somersault are derived according to how many times the contestant twists his body. 3. Horse Vault's Moon Somersault is expressed in the form that the contestant adds his twists to the whole process of a one-and-a-half-time somersault. 4. This study draws a plan on Moon Somersault in the parallel bars.

증기발생기 전열관 검사를 위한 차동형 원격장와전류 탐촉자 설계

As steam generator (SG) tubes have aged, new and subtle flaws have appeared. Most them start growing from outside the tubes. To find outer diameter defects more easily, the author had shown that the remote field eddy current (RFEC) technique, which had shown equal sensitivity to inner diameter (ID) and outer diameter (OD) defects, is feasible for the inspection of SG tubes. Based on the results obtained in that study, this paper designed a differential RFEC probe and studied the characteristics of differential RFEC signal. Finite element modeling studies show that the differential signal still has the equal sensitivity to ID and OD defects and at the same time it is possible to distinguish one from the other. Also noticed is that there is few degrees of signal rotation but sensitive changes in signal length when the depth of small defect varies. If the volume of defect is large, the changing rate of signal length is higher than that of defect size variation. The characteristics of signal show that the proposed differential RFEC technique can be a good alternative for the initial inspection of SG tubes.

손짚고 뒤돌기의 動作分析

The purpose of this paper is presenting helpful materials for direction and advancing skills by analysing motions of back handspring of the gymnasts who represent the province. After photographing back handspring motions of four college gymnasts who took part in the 64th National Athletic Meeting in the series of three-step running pace, round off, back handspring, tucked backward somersault with a movie camera (37 frame/sec), I could get the locus of motions. I compared the motions with ideal motions presented by specialist and get the following conclusion. 1. At the first landing, I found that they landed in a motion leaning forward by about 70°. I think this defect can be corrected through strong snap down practice in round off. 2. At the first landing, they erected their heads in 163°∼197°, and arms came down by 15° from the horizon when landing. I think this is a disadvantage to them in getting speed when the body is bent backward with arm-swing, and this defect can be corrected through the practice of landing with arms attached to ears. 3. At the phase from the first landing to the take-off, when bending the body backward, the head bent backward before swinging the arms. I think this is a disadvantage to them in getting sufficient speed when bending the body backward, and this defect can be corrected through the practice in which arms is attached to the arms intentionally in swinging arms backward. 4. At the phase from the first landing to the take-off, they swung their arms without relaxing the wrist. I think this is a disadvantage to them in bending the body speedily. 5. At the phase from take-off to hand touch, the legs were spread out during the inflight motion. I think this results from the gymnasts' habit of reducing the time which is used in tumbling by shorting their bodies, and this phenomenon happens among trained gymnasts unconsciously, reflectively and frequently. 6. In hand touch, the shoulder line was not cut, which is necessary so that the arms might be vertical against the land. I think this results from not getting sufficient speed in bending the body backward. 7. After the hand touch, the shoulder went forward and legs snaped down a little after the apex. I think this phenomenon happens because the hand off is delayed and the gymnast can't snap down the leg strong.

Since German, Swedish and Danish periods in the early nineteenth century, gymnastics has been spread all over the world, technically developed and systematized as a modern artistic one. Men's gymnastics comprizes Floor Exercise, Parallel Bar, Horizontal Bar, Vaulting Horse, Pommel Horse and Rings. Women's gymnastics is made up of Floor Exercise, Uneven Bars, Vaulting Horse and Balance Beam. The evaluation of each event except for Vaulting Horse is divided into four individual factors-Value Parts, Execution, Combinations and Bonus Points. The evaluation of Vaulting Horse is distinguished from the others by means of the principles of one performance one technique. The purpose of this study is to grasp the characteristics ans technical construction of Vaulting Horse.
