신체활동은 노화로 의한 인지기능 저하에 긍정적 영향을 미친다. 하지만 신체활동 참여가 정서인지기능에 미치는 영향을 과학적으로 밝혀 낸 연구는 드물다. 따라서 본 연구의 목적은 청년기와 노년기 성인의 정서인지 기능에 신체활동 참여가 어떠한 영향을 미치는지를 뇌 과학적으로 연구하는 것이다. 연구의 피험자는 D 광역시 성인 남성 60명으로 선정하였으며, 청년 운동 집단(25∼35살), 청년 비 운동 집단(26∼35살), 노년 운동 집단(60∼70살), 노년 비 운동 집단(60∼70살) 4개의 집단으로 구성하였다. 실험도구는 EEG 측정 장비와 국제정서사진체계(International Affective Picture System: IAPS)를 사용하였다. 본 연구의 실험과제는 사진으로 제시하는 세 가지 정서자극(긍정적, 중립, 부정적)에 적합한 버튼을 눌러 정서적인지 검사를 실시하였다. EEG 측정은 8개(Fp1, Fp2, Fz, C3, C4, Cz, T3, T4)의 영역을 측정하였다. 통계처리는 4(집단)×3(자극)×8(영역)에 대한 삼원분산분석을 실시하였다. 결과: 본 연구 결과, 반응시간과 반응정확률 그리고 P3 잠재기는 집단간 주효과가 나타났다. 그리고 P3 진폭은 집단과 자극간 상호작용이 나타났다. 결론: 신체활동은 청년층과 노년층의 정서적 인지기능에 긍정적인 영향을 미치는 것으로 나타났다.

Background: Given the potential benefits of wellness programs promoting physical activity of the community-dwelling frail elderly, it is recommended that comprehensive wellness programs combined with the component of physical activity. This may improve overall health and potentially lower the health care cost of the frail elderly. In general, the frail elderly residing in community or those after being discharged from hospitals are often committed to enhancing the status of participation in physical activity. Objects: The purposes of this study were to identify specific shortcomings of current wellness programs as part of continuum of community rehabilitation services and to propose alternatives for the care of the community-dwelling frail elderly. Through this study, geriatric health care professionals may be able to implement assessments and programs to successfully promote an effective continuum of care for the frail elderly. Methods: Article reviews were summarized and evaluated. Results: A model elaborating the relationship between components of successful wellness program and participation in physical activities for the community-dwelling frail elderly are recommended. First, periodic monitoring the levels of physical activity by the use of online measurement system should be considered. Second, individualized adaptive technologies for selecting optimal physical activities for the elderly may be better fit to individuals’ current status of physical activity. Conclusion: The current status of physical activity in community-dwelling frail elderly can be monitored by online assessment systems. Through the innovative measurement system, elderly may assess his/her physical activity status overtime, select optimal physical activities matching the status, and create the elderly’s own adaptive wellness programs that match to the status while residing in his/her community.

The purpose of this study was to investigate how the parent’s game addiction has an effect on children’s physical activity, physical self-conception was used by medium. Participants were 230 mothers with children between 5 and 7 years old. One-hundred eighty surveys, excluding those with omitted or odd answers, were analyzed. The data were analyzed with descriptive statistics, bivariate correlation analysis, path analysis using WEB-R 3.0(LAVAAN). The first, as the result indicated, parent’s game addiction affected the children’s physical activity directly. The second, parent’s game addiction affected the children’s physical self-conception. The third, children’s physical self-conception. affected the children’s physical activity. Therefore the effort to increase the children’s physical self-conception may contribute to developing children’s physical activity.

This study describes the effects of treated water (TW) on PH changing, growth of watermelon seedlings, canola oil and diesel absorption, the antibacterial ability of the filter that composited from polyurethane(PU) and silver powder(Ag) producing by Electrospinning. In this study, we used the battery energy acquired from solar cell, the water has been processed when it pass through the electromagnetic field. The results of this research indicated that the PH value of TW changed slightly compared with untreated water (UW), but the TW could absorb smell of PH reagent. In addition, the TW could also promote the growth of watermelon seedling, and the growth of watermelon seedling stem length was about twice compared with UW. On the effects of canola oil and diesel absorption, the TW also showed a good oil absorptive capacity, especially for the diesel absorption, it could absorb 28% diesel. For the PU+PU+Ag/CNT filter, it showed about 100% of the antibacterial rate on strain 1 (Staphylococcus aureus ATCC 6538P) and 2 (Escherichia coli ATCC 8739).

Previous studies have investigated stepping over obstacles in treadmill walking training (TWT-OS) and treadmill walking training (TWT) alone for walking capacity not considering real physical activity. As such, we investigated the effects of TWT-OS on physical activity and changes in different levels of physical activity based on community ambulation in stroke patients. Thirty subjects were randomly assigned to either the experimental group or the control group, with 15 and 15 subjects, respectively. However, one subject from the control group was excluded because of inadequate treatment sessions. All subjects underwent routine physical therapy in the form of treadmill walking. The subjects in the experimental group underwent simultaneous training in obstacle-stepping while walking on the treadmill for 30 min/day, five times/week, for four weeks. Subjects were given a three-axis accelerometer to wear at the hip on a belt for one-week pre- and post-training physical activity. Step counts for seven days, average daily step counts, and the average of minutes spent in sedentary, light, and above moderate activity were chosen as outcome measures of physical activity. No significant differences between the groups were found in terms of step counts for seven days, average daily activity, or daily activity spent at sedentary levels after four-week interventions. However, the average daily activity spent at light levels (-42.60 min vs. -6.71 min) was significantly lower in the experimental group than in the controls. Conversely, average daily activity spent at above moderate levels was higher (19.86 min vs. 11.07 min) (p<.05) after adjusting for each baseline value. Significant pre- and post-training differences were found in all variables of the experimental group (p<.05). Thus, TWT-OS could improve physical levels above moderate activity as a community-oriented task more than simple repetitive waking on a treadmill, and it could provide an opportunity for patients ambulatory after stroke to participate in the community again.

This study aims to comparatively analyze lower extremity joint moment during the take-off phase in high jump and thus to provide the basic data for enhancement of highschool students' high jump skills. 2 highschool students - one males and one females - were chosen for the experiment in which the 3D image analyzer and ground reaction force measuring unit were adopted. The results are as follows: Similar to the changing patterns from lower extremity joint moment but, moment values it turned out that male were better than female. The flexion and extension moment of lower extremity were most significant, abduction and adduction, medial rotation and lateral rotation were relatively small. The moment value in sagittal plane, frontal plane, transverse plane were appeared larger in the order of hip joint-knee joint-ankle joint. The muscle activity of knee joint and hip joint were acts in conjunction with sequential knee joint-hip joint.

The Attention Deficit Hyperactivity Disorder (here in after referred to as "the ADHD") is one of the childhood developmental disabilities most frequently reported from the education field. Children suffering from the ADHD show unique tendencies of deficie

Osteoporosis is characterized by low bone mass and the microarchitectural deterioration of bone tissue with a consequent increase in bone fragility and susceptibility to fracture. It has been suggested that speed of sound (SOS) and broadband ultrasound attenuation (BUA) of quantitative ultrasound sonography (QUS) may provide information about not only bone density but also the microarchitecture and elastic properties of bone. Physical inactivity reduced mechanical usage and it made process to the bone changes. This study aimed to association between the physical activity and the QUS parameters in 1305 (593 men, 712 women) aged 20 years over in a rural population. Two QUS parameters, BUA (p=.23) and SOS(p=.73) were measured at the right calcaneus of postmenopausal women, no significant associations were observed between sports index and SOS and BUA. These results suggest that work, non-sports leisure physical activity (p<.01) have a significant influence on QUS parameters in a rural population. Physical activity are meaningful predictor of QUS parameters of the calcaneus in a rural population.

목적: 이 연구는 기본 심리 욕구 이론을 기반으로 생활체육 참여자의 심리적 욕구 만족과 심리적 욕구 좌절이 스 포츠 정서와 도덕적 행동과 어떤 관계를 지니고 있는지 규명하였다. 방법: 생활체육 참여자 334명(남성: 264, 여 성: 70)을 대상으로 설문조사를 진행하였다. 수집된 자료는 SPSS와 AMOS 프로그램을 이용하여 빈도분석, 기술 분석, 신뢰도 분석, 타당도 분석, 상관분석과 경로분석을 실시하였다. 결과: 첫째, 생활체육 참여자의 심리적 욕구 만족은 긍정 정서와 친사회적 행동에 정적인 영향을 미쳤다. 둘째, 심리적 욕구 좌절은 부정정서와 반사회적 행 동에 정적인 영향을 미쳤다. 셋째, 긍정 정서는 친사회적 행동에 그리고 부정정서는 반사회적 행동에 정적인 영 향을 미치는 것으로 나타났다. 이는 기본 심리 욕구 이론에서 제시하는 이분법적 접근과 일치되는 결과로 긍정적 선행변인(심리적 욕구 만족)은 긍정적 결과변인(긍정 정서, 친사회적 행동)을 더 잘 예측하고, 부정적 선행변인(심 리적 욕구 좌절)은 부정적 결과변인(부정정서, 반사회적 행동)을 더 잘 예측한다는 결과를 보여준다. 결론: 결론적 으로 생활체육 참여자의 심리적 욕구 만족은 긍정적인 정서를 경험하게 하여 친사회적 행동으로 이어지게 하며, 이에 반해 심리적 욕구 좌절은 부정정서를 경험하게 하여 반사회적 행동을 유발할 수 있다는 것을 보여준다. 이 는 생활체육 참여자들이 지닌 심리적 욕구의 만족과 좌절 경험이 인지적, 정서적, 심리적, 행동적 결과에 중요하 게 작용한다는 것을 시사한다.
