The purpose of this research was to investigate the effect of after maximal exercise, fatigue recovery and total antioxidant capacity level by black garlic intakes quantity before and after the exercise. The volunteers for this study were 18 male university students. Primary tests were examined of each subjects by graded exercise test using Bruce protocol. Each of 6 subject was divided 3 groups by matched method based. For the secondary tests, the groups of subjects were taken their materials before and after exercise as a blind test. After the ingestion, subjects were experimented of graded exercise test, using Bruce protocol, by treadmill until the all-out. The results of this experiment were obtained by using SPSS 12.0 statistics package, and the average (M) and standard deviation (SD) were calculated by Analysis of Covariance and Repeated measure ANOVA. The subsequent results were as follows; 1) Among the tested groups, black garlic ingestion after the BGGⅢ group was maintained the longest of exercise exhaustion time. There, however, was no significant changes of each other(p>.05). 2) In all the tested groups, BGGⅢ group showed the lowest heart rate of rest and playing exercise, and BGGⅢ group represented the highest of HR max. There was significant differences of each time(p<.001). and each groups(p<.05), and each groups and group verse time(p<.05). 3) Concentration of blood lactate showed significant differences of each time period(p<.001) however, was not shown significant changes of each groups(p>.05) or each groups and group verse time(p>.05). 4) Concentration of blood Hematocrit showed significant differences of each time period(p<.05) however, was not shown significant changes of each groups(p>.05) or each groups and group verse time(p>.05). 5) Concentration of total antioxidants showed significant differences of each time period(p<.05) however, was not shown significant changes of each groups(p>.05) or each groups and group verse time(p>.05). In conclusion, intakes of black garlic might by reduced fatigue recovery and total antioxidants part appeared with the fact that affects is affirmative. Therefore, effects as an ergogenic aid through the intakes of black garlic need obvious results by further studies.

The purpose of this study was to investigate the effect of the dark chocolate ingestion on the aerobic exercise capacity, the Creatine kinase and the antioxidant capacity. 7 male university students performed exercise as subjects for this study and the results were measured repeat edly during the research. Primary tests were examined of each subjects by graded exercise test using Bruce p rotocol. The results of this experiment were obtained by using SPSS 12.0 statistics package, and the average(M) and standard deviation(SD) were calculated by Repeated measure ANOVA. The subsequent results were as follows; 1) Exercise performance time, second intake results shows the highest level but there were no clear distinction(p>.05). 2) CK concentration in the blood during Dark chocolate intake period showed decrease depending on measuring time however, there were no clear distinction(p>.05). 3) Total antioxidant capacity during Dark chocolate intake unit time, shows clear distinction depending on measuring time (p<.05). In conclusion, the result of intake dark chocolate be - fore exercise shows that there isn`t significant differences in exercise performance, serum CK, total antioxidant capacity, but ingestion of dark chocolate have an effect on them partially.

연구목적: 본 연구에서는 학습 경험 설계(LXD)가 공학교육에 적합한 대안적 수업 설계 방식이라 가정하고 그 수업 사례를 선정하여 설계 과정 및 운영 효과를 탐색하는데 목적을 두었다. 연구방법: 대학 교육 특히 공학 전공 수업에서 학습 경험 설계 사례가 제한적으로 이루어졌다고 판단하여 단일 사례 연구를 연구방법으로 채택하였다. 공학 교육의 특성을 드러내는 전자기학 과목을 사례로 Thurber의 LXD 모형에 따라 분석하였다. 연구결과: 사례 수업의 교수자는 문헌에 나타난 양질의 학습 경험 디자인의 특성을 잘 반영하여 LXD를 위한 학습개입을 개발하였고, 그것이 과목에 대한 학습자의 동기에 긍정적으로 기여한 것으로 나타났다. 논의 및 결론: 공학 전공 수업은 물론 일반 수업에서 LXD 수업 설계의 확대를 위한 제도개선 및 지원방안을 제안하였다. Purpose: This study assumed that learning experience design could be a relevant alternative for engineering education, and so it aimed that a selected case of one was explored in its design process and implication effects. Method: A single case study was adopted as a research method since the case of learning experience design in higher education, in particular in an engineering class has been a few. The electromagnetics class, reflecting characteristics of engineering education, was selected and analysed based on the Thurber’s learning experience design model. Results: It was found that the lecturer for the adopted case developed learning interruption inclined to the qualified characteristics of learning experience design in the literature and this positively contributed to the learners’ motivation on the subject. Conclusion: A number of suggestions for improvement of system and support to expand LXD in general classes as well as engineering classes were given.

This study is intended to provide necessary resources for armature and elite athletes who want to practice Axe kick (Downward kick). In this study, three subjects of S. University majoring in Taekwondo were used and the muscle activities are analysed by the EMG (Electromyography) method during performance of Axe kick which is often used to attack on the opponent`s face for scoring. The results were summarized as follows: The total time of performing Axe kick took 1.06 seconds. Muscles of Rectus abdominis (RA) and Lumber erector (LE), External oblique (EO) were found to be used in the action. The Recrus femoris (RF) and Biceps femoris (BF) were used to increase the acceleration in performing strong Axe kick. Rectus abdominis (RA) was constantly used in the action and Tibialis anterior (TA) was used for center of the action. Tensor fasciae latae (TF) and Recrus femoris (RF) were used to lift up the lower part of the lower limb for Axe kick. Regarding many parts of the truck were used in performing axe kick, it may be significant to propose trunk strengthening training to be considered and applied in the actions of Axe kick performance.

The purpose of this study was Garlic and Black Garlic Ingestion on the After Maximal Exercise, Fatigue Recovery and Total Antioxidant Capacity. The volunteers for this study were 12 male university students. Primary tests were examined of VO(2)max of each subject by graded exercise test using Bruce protocol. Each of 6 subjects was divided 2 groups (GG, BGG) by matched method based on VO(2)max. For the secondary tests, the groups of subjects were taken their materials before and after exercise as a blind test. After the ingestion, subjects were experimented of graded exercise test, using Bruce protocol, by treadmill until the all-out. The results of this experiment were obtained by using SPSS 12.0 statistics package, and the average (M) and standard deviation (SD) were calculated by Independent and Paired t-test. The subsequent results were as follows; 1) BGG group was maintained the longest of exercise exhaustion time. There, however, was no significant changes of each other (p>.05). 2) In all the tested groups, BGG group showed the lowest heart rate of rest and playing exercise. There, however, was no significant changes of each other (p>.05). 3) As a result of each respiratory variables (VO(2), VCO(2), VO(2)max, RER, VE, RR) by intake, There, however, was no significant changes of each other (p>.05). 4) GG group was maintained the low of blood lactate. There, however, was no significant changes of each other (p>.05). 5) GG group was maintained the longest of exercise exhaustion time. After exercise, the data showed the significant changes of time period (p<.05). In conclusion, the prior to exercise and intake of after garlic and black garlic reach some positive effect to the Total Antioxidant Capacity. Therefore, effects as an ergogenic aid through the complex ingestion of Garlic and Black Garlic need obvious by further studies.
