The purpose of this paper is to develop the standard level of anxiety for competition, which can be effectively used to lesson the level of anxiety and then increase athletic performance in the games of team sports and individual sports. For this study the SCAT method developed by Martens was applied to 299 players who were participating in team sports or individual sports. Among the subjects, 207 players (term 106, individual 101) darticipated in the 12th athletic meeting of National Universities espesially 92 players (team 49, individual. 43) were chosen as the candidate players of various sports for '88 Olmpic games. The results of my investigation were as follows; 1. The scores of ANOVA test conducted between the groups of team sport players and that of individual sport player were F=5.57<F0.05(1.297)=3.84. The anxiety scores of the groups of individual sport players were higher than that of team sport players. The difference of the score is significant by the level of significance, 5%. 2. The score difference between the groups of '88 Olympic candidate players and the collegian players were F=10.51>F0.01(1.153)=6.63. When in team sports as for the individual sports the difference was F=4.55>F0.05(1.142)=3.84. The anxiety score of '88 Olympic candidate players by the level of significance 1% and 5% in team sports and individual sports respectively. 3. My date analysis showed that the average anxiety score of the Korean collegian palyers is 17.65. It is very noticeable that the average anxiety score 17.65 of Korean collegian players is lower than that of the American players. 19.74.

Tubex彈性抵抗과 Nautilus負荷抵抗의 트레이닝效果 比較硏究

鄭相澤,蔡鴻遠 慶北大學校 體育科學硏究所 1991 체육과학연구지 Vol.7 No.-

The principal purpose of this experimental study is to make the new training method by comparing each other the effect of Tubex elastic resistance and that of Nautilus load resistance to leg torques. The characteristics of tubex elastic resistance are not only the peak torque of motion stress which was given to muscles by the soft elastic resistance, in propotion to the angle of joints and to the torques but also the large developments of the stretching reflex and of the ankle joint snapping through the formation of the second ballistic phase at ankle joints. The characteristics of nautilus load resistance are the constancy of the load resistance of weight and the inerease of muscle strength and of muscular enduracne by the changes of the torques of the maximal muscle strength-velocity and by the formation of the neuralfacilitation of motion. In order to compare each other these heterogeneous characteristics, 16 soccer players of Kyong-Pook Univ were taken as subjects, who were divided into two groups. Tubex 8 persons and Nautilus 8 persons. Each groups were trained for 12 weeks, through the manimal swiftness method of motion musele of the 45 degree-leg-turning motion, in which were taken the week freguency 6 days, training tine 6 minutes, training strength 2.47J and 24㎏ and the gradual repetition 20∼25RM×3 set. This experiment was analyzed both by the logntudinal analysis of the two groups before and after the experiment and by the cross sectional analysis of the two groups after the experiment. The results are as follows : 1) As for the torque of 30°/sec and 60°/sec, the peak torque was statistically significant(P<.01), improved by 23.9 Nm(18%), 28.6Nm(22.9%) in tubex group and by 12Nm(8.8%), 9.6Nm(7.6%) in nautilus group, But no statistical significance could be found when the two groups were compared with each other(P>.05). 2) As for the effect of the maximal strength of the load velocity of motion, 60°/sec, 180°/sec and 240°/sec, the tubex elastic resistance was statistcally significant (P<.05, P<.01), increased by 11.4Nm(8.8%) 18.1 Nm(9.8%), 12.5Nm(12.9%), 13.8 Nm(10.1%), 15.4NM(18.19), 13Nm(11.7%) in tubex group and the nautilus load resistance was also statistically significant(P<.01), increased by 11.1Mn(8.6%), 14.9Nm(6.8%), 14.3Nm(14.7%), 15.4Nm(10.8%), 18.5Nm(22%) and 6.1Nm(5.0%). But when the two groups were compared with each other, no statistical significance could be found. 3) As for the porportion of muscular endurance at the load velocity of motion 240°/sec, in the case of the torque of extensor and flexor, the torques of the tubex elastic resistance was statistically significant,(P<.01), increased by 8.6Nm(14.1%) 11.5Nm(18%) and the torques of the nautilus load resistnace was also statistically significant(P<.01), increased by 12Nm(19.4%) and 11Nm(18%), But when the Two groups were compared with each other, no statistical significnace could be found (P>.05). 4) At the load velocity 60°/sec, 180°/sec, 240°/sec, the propotion of extensor and flexor was in the range 62%∼80% of tubex elastic resistance and in the range 59%∼81% of nautilus load resistance, which meant the normal, But when the two groups were compared with each other, no statistical significance could be found in each range of the load velocity.

AbstractThis study was carried out to offer the basic materials for the more efficient guidance of player as suggesting a guidance type preferred by players to field athletics leaders by measuring and analyzing the guidance behavioral type of coach preferred by athletes as well as to disclose the efficient method of coach's guidance.For the measurement, this study used questionnaires called the Leadership Scale for Sports (L, S, S) which Mr. Chelladurai and saleh(1978) developed as a measure of sports leadership in order to explain coach's behavior, and analyzed those questionnaires from 300 middle school students and High School students in Daegu metropolitan city and Kyungbuk-do. The results are as follows : Sex and career didn't affect the preference of players to coach's behavior, but players didn't preferred the autocratic behavior of coach. However, there was the significant difference at the age in preference of coach's behavior. Especially, young players were requiring the more training assignment and much more concern also in the human relation than mature players. The more the age, the less their requirement. In the above-mentioned results, it is considered to be effective in guiding players to change a method of guidance by player's age, whenever coach will guide players.

가울배추 재배농가의 경영효율성과 다극화 실태 분석

정상택,장철성,이향미 韓國食品流通學會 2015 한국식품유통학회 학술대회 Vol.- No.하계

본 연구에서는 2001년부터 2013년까지 가을배추 재배농가의 경영효율성을 측정하고, 경영효율성에서 측정된 순수기술적 효율성과 규모 효율성의 양극화 크기를 비교하였다. 또한, 경영효율성을 결정하는 요인으로 종자/종묘비, 무기질비료비, 유기질비료비, 농약비, 대농기구상각비, 제재료비, 고용노력비 등이 어떠한 영향을 미치는지 분석하였다. 가을배추 재배농가의 비효율의 주된 원인은 규모의 문제보다는 순수기술적인 요인으로 발생하고 있는 것으로 나타났고, 순수기술적 효율성의 양극화가 지속적으로 증가하는 것으로 나타났다. 또한, 경영효율성에 무기질비료비, 유기질비료비, 농약비, 대농기구상각비, 고용노력비 등은 많이 투입될수록 경영효율성이 감소하며, 제재료비는 많이 투입될수록 경영효율성이 증가하는 것으로 나타났다. 이는 가을배추 재배농가는 규모보다는 순수기술적 요인에 따른 경영효율성 제고가 가능하며, 경영효율성이 낮은 가을배추 재배농가 그룹에 대한 비효율적 요인들에 대한 적절한 컨트롤이 필요함을 시사하였다.

Engineering Antibodies for Improved Efficacy and Prolonged Serum Half-Life

정상택 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.0

Antibody Fc domain dictates therapeutic potency and circulating serum half-life of monoclonal IgG antibody by the interaction with the Fc ligands including FcγRs, C1q, and FcRn. To overcome the limitation of conventional monoclonal antibodies used in the clinic, researcher`s growing interest and engineering efforts in the last several years opened a new gateway to transformed IgG Fc into a highly evolvable unit for a new desired function. To enhance therapeutic potency and circulating half-life, various biomolecular, cellular and evolutionary approaches have been employed and will be discussed.

Tailoring Immunoglobulin Fc for Highly Potent and Serum-stable Therapeutic Antibodies

정상택 한국생물공학회 2013 Biotechnology and Bioprocess Engineering Vol.18 No.4

Antibody Fc region, a recruiter and a frontline commander in the combat against cancer and infectious pathogens, mediates potent immune effector functions by engaging Fc receptors and serum complement proteins. Recent studies indicate that the Fc region is particularly amenable to modifications that enhance potency and serum stability through amino acid substitution and glycan modification. In order to modulate the interaction of the Fc domain with Fc-binding ligands (FcγRs, C1q, and FcRn),various engineering strategies have been employed; these studies are discussed in this review.
