The purpose of the study was to investigate relationship between anaerobic reserve (AR) from critical power test and anaerobic capabilities from Wingate and isokinetic test. Three different tests were administered to 12 high school sprinters on a Monark cycle ergometer and Kin-com isokinetic equipment. Means, standard deviations, Pearsons product-moment correlations, and simple linear regressions were obtained by using SPSS-Window program. To examine the important factors contributing to AR, stepwise regression analysis were performed using anaerobic capabilities from Wingnte and isokinetic tests as independant variables. Based on the findings of the study, the following conclusion has been derived: 1. There were significant moderate correlations of anaerobic reserve with WIN10, WIN20, and WIN30 respectively. 2. There were not significant correlations of anaerobic reserve with any isokinetic extensor and flexor variables. 3. The stepwise regression analyses revealed that only WIN30 contributed to predicting anaerobic reserve (72.9%) significantly. In conclusion, the results of the study demonstrated that the critical power test is a reliable and valid method for the measurement of anaerobic ability in the high school sprinters. The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolysis. Also, the study provides preliminary data on the anaerobic abilities in the sport of sprint as assessed by the critical power test, Wingate test, and isokinetic test.

The effect of rubber mold on densification behavior of pure iron powder was investigated under cold isostatic pressing. The thickness effect of rubber mold was also studied. The elastoplastic constitutive equation based on the yield function of Shima and Oyane was implemented into the finite element program(ABAQUS) to predict compaction responses of metal powder under cold isostatic pressing. The hyperelastic constitutive equation based on Moony-Rivlin and Ogden strain energy potentials was also employed to analyze deformation of rubber mold. The coefficients of the strain energy potentials were obtained from tension and volumetric compression data of rubber. Finite element results were compared with experimental data for densification of pure iron powder under cold isostatic pressing.

N/A This study employed 11 university soccer players for assessing anaerobic capacities related to ATP-PC and/or lactate system. It was investigated correlation among anaerobic capacities from Critical Power test, from Wingate test, and from Isokinetic test. Also, the study investigated regression formula which could expect anaerobic reserve(AR) from variables measured in Wingate and Isokinetic test. There were significant but intermediate correlation between AR and WIN5, (r= .62, P< .05) and WIN30(r= .64, P< .05). There was no statistically significant but intermediate correlation between AR and WIN10 (r= .52, P> .05). The study used stepwise method for multiple regression by Wingate variables to produce AR. The result showed that WIN30 had significant effect and indicated regression formula (Y= 1.3323(WIN30)-14737.758) to explain 41.2% variation of AR. Stepwise method was done for multiple regression on Isokinetic variables to produce AR`s inferred possibility by extensors TW of 60˚ /sec as regression (Y= 10.6737 (TW)+2083.9403) explained 42.9% variation of AR. In the correlation between measured variables of Wingate and Isokinetic extensors there was no significance of intermediate correlation in 60˚ /sec PT and WIN5(r= .53, P> .05) and in TW and WIN5(r= .56 P< .05) statistically. Also, There was significance of intermediate correlation in PT and WIN10 (r= .65, P< .05), no significance in TW and WIN10 (r= .57, P> .05), in PT and WIN30(r= .58), and no significance in TW and WIN30(r= .46, P> .05). In the correlation between measured variables of Wingate and Isokinetic extensors, there was significance of intermediate correlation in 180˚ /sec PT and WIN10 (r= .69, P< .05) and significant correlation in Isokintic 180˚ /sec PT and WIN30(r= .65, P< .05). The data suggested that anaerobic reserve assess true anaerobic ability not including the energy component of anaerobic glycolyses. Also, the study provides preliminary data on the anaerobic abilities in university soccer players as assessed by the Critical Power test, Wingate test, and Isokinetic test.

양심적 병역거부에 대한 태도 분석: 사회학적 고찰

정진원(Jin Won Chung),구정우(Jeong-Woo Koo),오아라(Ara Oh) 한국사회학회 2021 韓國社會學 Vol.55 No.1

양심적 병역거부에 대한 지지태도에 영향을 주는 요인은 무엇인가? 개인의 안보에 대한 인식과 인권에 대한 태도는 이러한 지지태도에 어떤 영향을 주는가? 분석 결과가 안보와 인권에 관한 오랜 학문적, 정책적 논의에 시사하는 바는 무엇인가? 본 논문은 기존의 법학적 연구를 넘어 양심적 병역거부에 대한 국민의 태도에 초점을 맞추어 경험적, 사회학적 연구를 수행한다. 2018년 한국종합사회조사 자료에 대한 순서형 로지스틱 회귀분석 결과, 안보 가치를 중시하는 개인일수록 양심적 병역거부에 대한 지지도가 낮고, 인권 가치를 중시하는 개인일수록 지지도가 높음을 확인하였다. 이밖에도 개인의 사회인구학적 특성 및 사회경제적 지위, 그리고 문화적 특성 역시 양심적 병역거부에 대한 개인의 태도에 일정한 영향을 주는 것으로 확인되었다. 이러한 결과는 한국적 맥락에서 안보와 인권이 여전히 대립적 관계에 있음을 잘 드러내 주고 있다. 나아가 양심적 병역거부 및 대체복무에 대한 국민적 지지를 높이기 위해 인권감수성 제고가 필요한 한편, 안보에 대한 개인적, 사회적 관점을 바꾸어가는 것이 중요하다는 정책적 함의를 제공한다. What factors affect individual’s attitude toward the level of support for conscientious objection to military service? How does an individual’s perception about national security and human rights awareness affect his/her level of support for it? What does the analysis result suggest us in terms of academic and political discussion of the relationship between security and human rights? The ordered logistic regression analysis of the 2018 Korean General Social Survey data confirms that people who value national security are less likely to support conscientious objection to military service, while people who value human rights are more likely to support it. In addition, individuals’ socio-demographic characteristics, socio-economic status, and cultural trait also have some impacts on their attitudes toward the conscientious objection to military service. The results reveal that security is still in conflict with human rights in the social context of South Korea. This study provides policy implication that it is necessary not only to cultivate human rights sensitivity, but also to change one’s personal and social perspective of security in order to attain public support for the alternative service system that is agreeable by the conscientious objectors to military service.
