  • Through a investigation of the physical activity status of 1794 undergraduates who were non-sports majors from freshman to senior in Jiangxi Normal University, to analyze physical fitness status of college students with different physical activity levels. The results showed that in physical activity, high-intensity physical activity of male was higher than female, while medium-intensity and low-intensity (insufficient) physical activity of female was higher than male. College students' high-intensity physical activity group's physical test scores were better than the medium-intensity physical activity group, and the medium-intensity physical activity group was superior to the low physical activity group. In terms of physical fitness, among the test indicators of body shape and physiological function, the vital capacity and body mass index of male and female were ranked at a pass level. In the physical fitness test indicators, the performance of college students' endurance qualities was better while the overall performance of strength qualities was lower. The overall fitness of college students was ranked at a pass level, and the physical test scores of female were better than male.

  • 본 연구의 목적은 PAPS를 실시하여 4, 5급에 해당하는 저체력군 학생을 대상으로 16주 복합운동프로그램을 통해 대사증후군과 자율신경계에 어떠한 변화가 나타나는가를 규명하는 것이다. 16주 복합운동프로그램은 주 5회에 걸쳐 준비운동, 본운동, 정리운동으로 구성하고 1회 50분씩 실시하였다. 자료처리는 SPSS 19.0 통계프로그램을 이용하여 모든 종속변인들의 평균과 표준편차를 산출하였다. 샤피로-윌크 검정값을 이용하여 정규성 검정을 실시하였고, 복합운동집단과 통제집단의 모평균 차이를 위하여 독립표본 t-검정을 실시하였으며, 16주 복합운동프로그램 전 후 각 집단 내변인들의 변화를 알아보기 위해 대응표본 t-검정을 실시하였다. 모든 통계치의 유의수준은 ${\alpha}$=.05로 처리하여 다음과 같은 결과를 얻었다. 본 연구 결과 대사증후군 지표에서는 허리둘레, 중성지방, 공복혈당, HDL-C에서 유의한 차이를 나타냈고, 자율신경계 요인에서는 통계적으로 모두 유의한 차이가 나타나 저체력군 고등학생에 긍정적인 영향을 미친 것으로 사료되어 진다.

  • Purpose: The purpose of the study was to identify the mediating effects of social support and self-efficacy between academic stress and college adjustment in physical therapy students. Design: Survey. Methods: 75 subjects were surveyed about the level of academic, Academic Stress, College Adjustment, Social Support, Self-Efficacy, and self-control. To confirm the cognitive function on brain activity were evaluated. Results: First, College students have higher academic stress and lower college adjustment. Higher social support and self-efficacy have lower academic stress and better college adjustment. Second, students with high academic stress need constant attention to increase their social support and programs to reduce academic stress. Third, students with high academic stress, low social support, and low self-efficacy can increase their cognitive strength through the brain wave thereby reducing the academic stress they are currently feeling. Conclusion: In order to improve the College Adjustment, it is considered that it is important to increase the cognitive function through brain train along with the development of a student management program that can reduce academic stress and increase social support and self-efficacy.

  • 본 연구의 목적은 습관형성모델을 기반으로 간호대학 여학생의 신체활동 정도와 신체활동에 미치는 영향요인을 파악하여 간호대학 여학생의 신체활동 증진 및 유지 전략을 개발하는데 기초자료를 제공하기 위함이다. 연구대상은 J시에 소재한 G대학교와 J대학교에 간호학과에 재학중인 여학생 207명이었고, 자료수집 기간은 2020년 8월 31일에서 9월 13일까지였다. 자료 분석은 IBM SPSS Statistics Ver. 22.0 통계프로그램을 사용하여 빈도, 백분율, 평균, 표준편차, ANOVA 및 Scheffĕ test, Pearson's correlation coefficient, Univariate, and Multivariate multinomial logistic regression을 이용하였다. 연구결과 간호대학 여학생의 신체활동 정도는 평균 2506.31±2807.05 MET-min/week이었고 신체활동 분류기준에 따라 세 군으로 분류한 결과 건강증진 신체활동군은 59명(28.5%), 최소한 활동군은 98명(47.3%), 비활동군은 50명(24.2%)으로 나타났다. 다변량 로지스틱 회귀분석에서는 신체활동 습관강도가 간호대학 여학생의 신체활동에 유의한 영향요인으로 규명되었다. 따라서, 간호대학 여학생의 신체활동 증진 및 유지를 위해 습관형성 프로그램을 개발하고 효과를 검증하는 연구가 필요하다.

  • 본 연구에서는 한 가지 염으로 포화된 수용액에 다른 염을 녹이면 얼마나 녹을 것인가에 대한 초-중등 학생들과 교사들의 이해 정도가 낮은 이유를 알아보기 위하여 중등학교 교과서와 대학교 교재의 서술 내용을 조사하였다. 그 결과 중등학교 교과서와 대학교 일반화학 교재에서는 다른 염의 존재 여부와 상관없이 용해도는 일정함을 전제로 서술하고 있었으며, 대학교 물리화학 교재에서는 다른 염의 존재에 의해 용해도가 달라짐을 직접 언급하거나 이를 알 수 있는 내용이 서술되어 있었다. 그러나 물리화학을 이수한 사범대학 4학년 학생들을 대상으로 조사해본 결과 학생들의 대부분이 이러한 용해도 변화에 대한 설명을 하지 못하였다. 따라서 교사나 예비 교사들의 의문을 해소하기 위해 이온쌍 형성과 이온 세기 변화에 따른 용해도의 변화를 설명하고, 실제 실험 결과도 하나 제시하였다. 하지만 중등학교에서는 활동도 개념의 도입이 어려우므로 두 가지 염이 동시에 용해될 때의 용해도를 어떻게 가르칠지에 대한 논의가 필요한 것으로 생각된다.

  • Purpose : To identify changes and relationships in the fat mass and obesity associated (FTO) gene polymorphism, body composition, and physical fitness from childhood to adolescence over a three-year period spanning elementary school to middle school (2015-2018) Methods : A total of 84 male student participants were divided into two groups based on FTO genotype: aa+at (group A) and tt (group T) and tracked down. Body composition, cardiovascular endurance, flexibility, muscle strength, power, and other characteristics were measured in the two groups in both 2015 and 2018, respectively, and the changes over the three-year period were analyzed and compared. Results : Increases in height and weight did not differ significantly between the two groups, but body mass index (BMI) was significantly higher in group A (p=.035). With regard to physical fitness, there was no significant difference in flexibility, but cardiovascular endurance, strength, and power were significantly higher in group T (p<.001, p=.063, and p=.040, respectively). Conclusion : Group A is more likely to become obese than group T because of their lower level of physical fitness and increased BMI relative to group T. This result supports previous studies showing that group A has a relatively low level of physical activity and a greater tendency to eat fatty foods as compared with group T. Therefore, we suggest that the FTO gene polymorphism should be identified early and that students educated on diet and physical activity to help prevent adult obesity.

  • Purpose : The purpose of this study was to investigate thigh muscle-bone CSA and leg strength during low-intensity exercise program with leg blood flow restriction by external compression to reduce muscle outflow. Methods : Eighteen health students gave informed written consent to participate in this investigation. An occlusion cuff was attached to the proximal end of the leg so that blood flow was reduced during the training. The training was conducted one times a day, three times a week, for 8 weeks using one sets of 30 minutes. The training program performed to squat with standing, lunge with standing and heel raise with one leg standing. Measurements of thigh muscle-bone CSA(cross-sectional area) and leg strength were evaluated pre and post-training. Statistical evaluation of these data was accomplished utilizing a paired t-test by SPSS 12.0 program for windows. Significance level was set at p <.05. Results : All data are reported as means and standard deviations(SD) for all variables. The result of the study is followed; After the training, muscle-bone CSA, gluteus maximus m, quadriceps m, hamstring m of both legs were significantly improved but not calf muscle(p<.05). There was no significant difference of change quantity between muscle-bone CSA and leg strength in Lt. and Rt. side. But the variation in leg muscle strength of Rt. leg(dominant) was much more increased than Lt. leg(non-dominant) after 8 weeks training. Conclusion : Low-intensity training with leg blood flow restriction offers a potentially useful method for improving leg muscle strength.
