신영진,鄭吉煥,高錫梵 全北大學校 基礎科學硏究所 1978 基礎科學 Vol.1 No.1

Thin films of solid state were made from solutions of organic polymers of different molar mixtures of poly-N-vinyl carbazole (P.V.K) and 2,4,7 -trinitro-9 - fluorenone(T.N.F). The donor, P.V.K. and the acceptor, T.N.F. molecules form a charge transfer complex. Meassuring the color purity of the thin films by using the C.I.E color system we found that the color purity of these polymers was increasing as the molar ratio varied from 1:0.2 to 1:0.6, 0.2 and 0.6 being TNF. This means that these organic polymers form a charge transfer complex up to the molar ratio 1:0.6. It was also found that this charge transfer complex can be classified as intermediatly interacting one by electrical property of these polymers.

The purpose of this study was to offer gymnasts data for successfully performing triple back somersault dismount(TBSD) and for designing training programs to progress gymnasts to the advanced dismount skills from the horizontal bar through comparative analysis of selected biomechanical factors of single back somersault dismount(SBSD), double back somersault dismount(DBSD) and TBSD. The subjects employed were a total of 4 male middle and high school gymnasts aged between 15 and 16 years. A motion-picture camera, fliming at a nominal rate of 54 frames/s, was used to record the performance of subjects on each trial. This camera was placed at a distance of 15 m from the inward pole of horizontal bar with its optical axis at right angle to this pole. The results obtained are summarized as follows: The mean release angle was 80.5° for the SBSD, 77.3° for the DBSD and 71.3° for TBSD. There were significant differences between the SBSD and the TBSD(p<0.01), the DBSD and the TBSD(p<0.05) but no significant difference between the SBSD and the DBSD. The angular velocity at release was 4.533 ㎭/s for the SBSD, 5.338 ㎭/s for the DBSD and 6.020 ㎭/s for the TBSD. There was a significant difference among these velocities(p<0.05, p<0.01). The linear velocity at release was 5.458m/s for the SBSD, 5.750m/s for the DBSD and 6.083m/s for the TBSD. In this case, we had a significant difference only between the SBSD and the other two somersaults(p<0.05, p<0.01). The shoulder angle at release was 170.5° for the SBSD, 167.0° for the DBSD and 154.3° for the TBSD. There were significant differences between the SBSD and the TBSD(p<0.05), the DBSD and the TBSD(p<0.05) but no significant difference between the DBSD and the TBSD. The hip and knee angle at release were increased respectively by increasing the number of somersault but showed no significant difference among these angles. The mean flight time from release to landing for each somersault was calculated; it took the subjects 1.315s to perform the SBSD, 1.345s to perform the DBSD and 1.416s to perform the TBSD. There was a significant difference among these somersaults with respect to time(p<0.05, p<0.01). The mean maximum height was 3,633m for the SBSD, 3,720m for the DBSD and 3,780m for the TBSD. There was a significant difference only between the SBSD and the other two somersaults. The mean horizontal distance was decreased respectively by increasing the number of somersault but showed no significant difference among these somersaults with respect to distance. The smallest hip angle during flight in the SBSD was 115.3° at 0.317s after the subject left the bar, for the DBSD it was 48.2° at 0.621s while that of the TBSD was 32.3° at 1,102s after release. The relationship between the time the smallest hip angle observed and the total flight time was determined; it took 24.1% of the total flight time of the SBSD to reach the smallest hip angle. In the DBSD, it took 46.2% of the total flight time to reach for the smallest hip angle and in the TBSD 77.8% of the total flight time to reach the smallest hip angle. From the above results, the gymnast would need to (1) increase angular velocity before release by manipulating of body shape, (2) change the release angle and (3) stay tuck position longer by shortening as quickly as possible the angle of each body joint to perform successfully the TBSD. Also to be able to perform quadruple back somersault dismount, a gymnast would need flight time of a minimum 1,782s.

鐵棒 뒤 공중돌아 내리기와 겹 공중돌아 내리기의 動作分析

申榮吉,康榮洙 慶北大學校 師範大學 體育學硏究會 1986 體育學會誌 Vol.14 No.-

This study in movement analysis as a result of have extracted the following conclusions. 1. It was disclosed that all subjects released the bar at almost some angle, Once back somersault was released angle 86°∼92°, and Twice back somersault at angle 85°∼86°. 2. It was disclosed that a performer would diminish the body angle of himself in order to speedily swing the second round than first while perporming twice back somersault. 3. The power which canthrust the trunk of a performer was originated when swinging speedily and having small shoulder angle as soon as release-the hands and this power can thrust the center of his weight. And by doing so, I think that the somersault can be nicely performed. 4. Somersault should have the power of thrusting feet while swinging because this power can originate other power which can originate other power which can perform second round. I belive that only round-speed accelerated by the falling power can round third or fourth somersault. 5. While once back somersault has much angle difference with angle 26°∼45° from the bar, twice back somersault perform first-round at almost same point as angle 32°∼34°. But the angle of second-round(O_3) has much difference with angle 32°∼4°. This fact, we think is the differentia of round-speed.

뜀틀(Long Horse)의 技術變遷에 따른 演技內容에 關한 考察 : centering around the Montreal Olympics

申榮吉 慶北大學校 1979 論文集 Vol.27 No.-

The summary of surveying and analyzing the tendency to perform the Long Horse is as follows: Of 100 male players, 76 of them were reported to perform such gymnasic maneuvers as the Hand Spring Salto (style A), the Hand Spring with Full Turn, the Tsukahara Vault (style B), and the Kasamatsu Vault. The Kasamatsu Vault especially received recognition as the best technique. In case of female players, they generally performed no more than three kinds such as the 1/2 Turn Back Somersault (style A,B), the Hand Spring with a Full Turn, the Hand Spring Salto (style A,B). This was well displayed by Nelly Kim, a USSR somersaultist, as she performed the 1/2Turn to Back Somersault with a Full Turn in a new mode. In case of Korea, it was found in the competition for selecting national representative players that the Tsukahara Vault(style A,B), the Hand Spring Salto were generally used by male players who participated in it, and that the 1/2Turn to Back Somersault, the Tsukahara Vault, the Yamashita Vault, the Hand Spring with a Full Turn were popular among female players.

韓國 近代體操의 發達과 그 內容的 推移 : 形式體操時代를 中心으로 Focus on Formal Gymnastics Period

申榮吉,孫俊丘 慶北大學校 師範大學 1991 敎育硏究誌 Vol.33 No.-

The purpose of this research is to grasp the development and content shift of modern Korean gymnastics in formal period from 1895 to 1927. The results are as follows : a) Though some schools adopted gymnastics, in preparations to receive, as a school subject in Educational system period, concrete gymnastics activities were not presented enough. b) In school ordinance period gymnastics was a compulsory subject in most of schools and various kind of activities were shown to nurture physical strength. c) In Korea school ordinance period gymnastics didn't advance in its contents much more than those in school ordinance period. Gymnastics was a reflection of Japanese colonial educational policy and placed emphasis on the power of self-control rather than robust health. d) In Instruction syllabus period Swedish gymnastics was practiced and improved in quality. Gymnastics education came to have modern system, thereafter.

한국에서의 National Trust 적용가능성에 관한 연구

전영길 도립 강원전문대학 2000 道立 江原專門大學 論文集 Vol.3 No.-

National Trust movement, which developed in europe and then spread to several nations now, is considered as a special prescriptive alternative to secure sound taco-system. NT is not only used one theoretical concept, but also means the environmental management system or managerial anthority itself. NT movement emphasize the citizen's volunteerism, in that it should be practiced by land donation or devise of land owners. But recent discussion on NT movement is driven without the consideration of right restrictions of land owner's, neverthless it may directly infringe their absolute property right. So, NT should be recognized in the relation with the 'Traed-off' concept, which one's realization influnces another negatively. In the primary step to adapt England's NT model into Korea, more efforts to protect the right of landowners is essential.

한국 토지정보체계의 부처간 갈등조정 가능성에 관한 연구

전영길 도립 강원전문대학 1999 道立 江原專門大學 論文集 Vol.2 No.-

Land Information System(LIS) of Korea is composed of two basic sub-systems. They are Cadastral system and registration system, which usually operated by other departments at each on 'redundancy rule'. But they produce much inconsistency between two main database, and it influences upon many aspects to manage or use data on land as a result of conflict between two departments. For the efficiency, it's essential to integrate two sub-system. And the most urgent duty for integrating this LIS is thought to coordinate the conflict between both sides. In several method for coordinating conflict. I used Raiffa's 'Negotiation Theory' as a model to analyse latent conflict and then find out the 'level of possibility' to settle the problems. As a comparative analysis with a similar example, these political implications, as below, can be suggested. 1) the Inter-organizational conflict can not be easily coordinated by simple negotiation process without any 'arbitrator'. 2) For not regarding such arbitrator, two departments can only lean on the effect of 'interaction'. But the result of this study insist that we won't have resonable resolution.

Photoluminescent and cathodoluminescent (Zn, Cd)S phosphors are prepared by firing at 850℃ in N_2 gas of atmospheric pressure for an hour. They are doped with (1) an activator CuS, (2) an activator CuCl, (3) a flux NH_4Cl, (4) both an activator CuCl and the flux NH_4Cl, an (5) not doped with either one. The crystal structure of ZnS phosphors powder is the mixed phase of cubic and haxagonal, while the powders of (Zn, Cd)S : Cu (Zn, Cd)S : Cu, Cl and (Zn, Cd)S phosphors are the hexagonal pattern under the same firing condition. Photoluminescent and cathodoluminescent cells are made with these phorsphors and their emission spectra are measured at room temperature after these materials are excited with 3650 A˚ light and cathode rays. These spectra are shifted from blue (green) to red wavelength as the CdS content of the phosphors is increased, The NH_4Cl flux is found to help the doping of the impurity energy level and it has SA center in SA emisson. The following two results are also observed about (Zn, Cd) : Cu;(1) the values of lattice parameter a are varied linearly with the molar fraction of (Zn,Cd) (2) the impurity changes with quadratic curve when the molar fraction is varied.
