최근의 완전학습에 관한 연구동향은, 완전학습에다 변인들 각각을 가법적으로 적용시켜 2σ수준으로 효과량을 높이고자 하는데로 모아지고 있다. 본 연구는 실제 학교 학습상황에서, 학습과제 해결에 필수적 요인인 선수학습 변인과 새 학습과제에 대한 유의미 학습이 조장되도록 하는 조직자 변인을 완전학습과 결합시킨 결과,세 변인이 가법적으로 작용해서 각각의 개별 효과량보다 높은 1.68의 종합효과량(combined effect size)이 나타나는 것으로 검증되었다 따라서 본 연구는 완전학습 수업조건에다 변인들을 결합시켜 얻은 가법적인 종합효과량이 20수준에의 도달을 가능케 하는 접근방법임을 시사해 주었다.

This study was to investigate the effects of unstable surface combined exercise on fall-related fitness and gait function in elderly women. The subjects were 33 elderly women who were randomly divided into exercise group (n=18) and control group (n=15). Subjects have participated in unstable surface combined exercise on a as resistance, balance, and walking exercise 3 times a week for 60 minutes for 12 weeks. Fall-related fitness including isokinetic leg strength, coordination, and balance was measured in accordance to a standardized fitness assessment manual. Gait function including gait speed, stride length, double support, cadence, gait cycle was measured by Optogait. Two-way ANOVA with repeated measures were used to test significant time by group interactions for measured variables at α=.05. In results, the fall-related fitness as figure 8 walks (p=.014), functional reach test (p<.001), close-eye standing test (p<.001), isokinetic leg strength (left: p<.019, right: p=.001) and gait function variables as stride length (p=.005), double support (p=.009) were showed significant interaction between measured time and group. In conclusion, the current findings of the study suggest that combined exercise in unstable surface provides a safe and effective means against fall prevention, such as improvement of fall-related fitness and gait function in elderly women.

Initial EMF stabilization behavior of the electrochemical CO2 sensor based on the galvanic cell, Pt, O2, CO2, Na2CO3//Na β-Alumina//Na2Ti6O(13)-TiO2, O2, Pt is investigated using electrochemical impedance spectroscopy (EIS) combined with EMF measurement. From the measured impedance spectra variation with time, it is deduced that the continuous increase in EMF at early operation stage is deeply related to the sluggish stabilization process of reference electrode material, Na2Ti6O(13)-TiO2, adopted in CO2 sensor rather than carbonate sensing electrode which is quickly stabilized. Fast stabilization of reference material of two phase mixture is the key in order to make the electrochemical CO2 sensor applicable for wide range of fileds and replacable with NDIR analyzer.

The present study attempt is to find out the effects of the aqua massage therapy on blood fatigue materials depending on types of sports massage administered for effective recovery after the maximum Exercise test among people who shared living sports. The study subjects were total 24 male college students majoring in physical education, designated to 3 groups(8subjects/group) administered with different types of therapies in convalescence: rest recovery (RR), sports massage (SM) and aqua sports massage (ASM) so that changes of lactate and ammonia levels in blood were comparatively analysed. The changes in ammonia among groups in convalescence after sports therapies, ASM group showed more reduction on average compared with SM and RR groups. The changes in lactate after sports therapies among group in convalescence, RR group showed less decrease on average compared to ASM and SM groups. In view of convalescence from fatigue after all-out, compared to RR group, SM and ASM groups’ lactate and ammonia levels in blood were found to decrease significantly, indicating the effects of massage on effective reduction in fatigue, which seems attributable to the notable harmony between hand pressure and buoyancy in water.

Purpose: The study aims to identify the relationship among self-management, exercise commission and athletic performance in team sports athletes. To achieve this goal high school and university (basketball, volleyball, baseball, and soccer) athletes were selected as subjects from the 2020 Korea Sports Council’s registered team sports athletes. Method: A total of 373 copies of data collection through surveys were used as final data. Data analysis was conducted with frequency analysis, reliability analysis, and regression analysis to demonstrate the following conclusions. Results: First, interpersonal, mental, and training management factors, which are sub-factors of self-management of group sports athletes, were shown to have a significant impact on the exercise commission factors. Second, it was found that interpersonal, physical, and training factors of group sports athletes significantly affected performance factors. Mental and training factors significantly affected performance factors. Mental, physical, and training factors significantly affected performance factors. Third, the relationship between self-management and athletic performance of team sports athletes has been shown to have a partial mediating effect. Conclusion: Based on this, it is expected to help players who play at sports sites and show their individual skills and also improve the team’s performance.

This study was to analysis how concentrated liquid oxygen intake after high-intensity exercise effect of elite athletes’ oxidative stress and antioxidation, blood fatigue substances, cardiovascular factors, and to define the usability of the intake. The study subjects were total 9 male elite athletes. With the exercise intensity equal to VO₂max80% which was calculated on Bruce protocol based maximum exercise stress test, the study subjects had done high-intensity exercise for 40 minutes on treadmill. To minimize the previous learning effect of exercise stress test, they had oneweek wash-out period, and the three groups of control, placebo, and GO₂ had cross-over design three times for three weeks. To compare interaction effects, two-way ANOVA (3RG×4RM) was conducted. In order to the significant difference in a repeated period, LSD post-hoc test was conducted for examining significance. The change in timebased SOD (p=.002), lactic acid (p<.001), blood pressure (systolic: p<.001, diastolic: p=.004), and heart rate (p<.001) depending on concentrated liquid oxygen intake was significantly different in each measurement time. Findings of this study suggest that intake of concentrated liquid oxygen as one-time single substance after high-intensity exercise was limited positive effect on SOD, lactic acid, and cardiovascular factors.

This study was to examine the independent and combined association of abdominal obesity and relative handgrip strength levels with increased cardiometabolic risk facotrs in type 2 diabetes elderly. The data from the 2016-2019 Korea National Health and Nutrition Examination Survey(KNHANES) were used. The subjects were 1,085 type 2 diabetes patients aged 65 to 79 years. Subjects were classified as Low WHtR & low relative HGS group, Low WHtR & high relative HGS group, High WHtR & low relative HGS group and High WHtR & high relative HGS group based on WHtR and relative HGS levels. Binary logistic regression analyses were used to determine the odds ratiod (ORs) and 95% confidence interval (CI) of cardiometabolic risk for having abdominal obesity and relative HGS levels. As a result of the analysis, after adjustment for age, weight, body mass index, alchol, smoking, and aerobic physical activity, only the High WHtR & low relative HGS group showed an increased(OR=1.695; 95% CI, 1.108-2.593) risk of exposure to cardiometabolic risk than the low WHtR & high relative HGS group. The results of this study suggest that the combined role of reducing abdominal obesity and increasing grip strength in the elderly with type 2 diabetes is more important in reducing the risk of cardiovascular and metabolic diseases than their independent roles.
