PURPOSE: The purpose of this study was to analyze the differences of bone density and structure after immobilization prior aerobic exercise and resistance exercise. METHODS: Twenty four mice were randomly divided into 3 groups: CC: 4weeks control cage after 2weeks immobolization (n=7), RT: 4weeks resistance training after 2 weeks immobilization (n=7), AE: 4 weeks aerobic training after 2 weeks immobilization (n=7). The prior exercise was performed aerobic and resistance exercise. The body weight, muscle weight, and bone morphometric microstructure parameter including bone mineral density (BMD), bone specific surface (BS/BV), percent bone volume (BV/TV), trabecular thickness (Tb/Th), trabecular number (Tb/N), trabecular separation (Tb/Sp), structure model index (SMI), connectivity density, and cross-sectional area was evaluated using by microcomputed tomography (micro-CT). One-way repeated ANOVA was used to evaluate the differences between three groups and paired t-test analysis was applied to examine the different between immobilization leg and non-immobilization leg. RESULTS: The results of this study indicated that the body weight was increased after 4 weeks, and decreased after 2 weeks immobilization. The gastronemius and soleus muscle weight was significantly decreased in immobilization leg compared to non-immobilization leg. BMD, BV/TV, BS/BV, Tb/Th, Tb/N, Tb/Sp, and Cross-sectional area in immobilization leg of CC was lower than immobilization leg of RT and AE. CONCLUSIONS: These results suggest that 4 weeks prior exercise might improve the bone density and microstructure, even though 2 weeks immobilization. Especially, the prior resistance exercise has more beneficial effects on muscle weight, bone density and microstructure.

The purpose of this study was to survey teachers' perception of classroom space utilization through analyzing the physical environment of elementary school classrooms (56 classrooms in 10 schools). Most of the teachers arranged desks in the two person parallel type (sectional layout : standard type) for their classes. Although the number was small, some classrooms used the T type, H type, U type, group type, and the teachers of such cases used these layouts for children's play activities or group learning. Some teachers changed the desk layout depending on the contents of learning or for different atmosphere of class, but about 40% of the teachers used the same classroom layout without any change during a semester. When the teachers' perception of classroom space utilization was examined according to the type and change of desk layout, the quantity and characteristics of posts, the position of posting spaces, and the size of activity spaces in the classroom, most of the teachers tended to be conventional without any characteristic, and only 16% of them were relatively active in utilizing classroom spaces. In addition, teachers of a relatively small class were more active in utilizing classroom spaces. In particular, perception was very low to utilize the classroom as a space for children's life or play activities or various types of learning. These findings suggest that it is necessary to improve teachers' perception of classroom space utilization in the future.

본 연구는 중학생이 인식한 부모의 과보호적 양육태도가 이들의 분노 정서에 미치는 영향을 특성분노와 분노표출의 관점에서 알아보았다. 특히 과보호적 양육태도가 분노에 미치는 영향의 과정에서 부정적 자동적 사고가 매개역할을 하는지 분석하였다. 이를 위하여 중학교 2∼3학년 603명을 대상으로 빈도분석, 평균차이검증, 상관분석 및 일련의 중다회귀분석을 사용한 매개분석을 통해 자료를 분석하였다. 연구결과 첫째, 자녀가 인식한 부모의 과보호적 양육태도와 이들의 특성분노의 관계에서 부정적 자동적 사고의 부분 매개효과가 확인되었다. 둘째, 자녀가 인식한 부모의 과보호적 양육태도와 이들의 자녀의 분노표출 사이에서 부정적 자동적 사고가 부분매개변인임을 확인하였다. 이를 통해 아버지와 어머니 모두의 과보호적 양육태도는 자녀의 부정적 자동적 사고를 유발하고 이렇게 유발된 생각에 의하여 특성분노가 높아지거나 분노표출의 정도가 높아진다는 것을 확인하였다. 본 연구의 결과를 바탕으로 부모의 과보호가 자녀의 정서 변화에 미치는 측면에서 효과적인 양육태도를 논의하였다. 그리고 본 연구 결과를 토대로 자녀의 문제행동을 해결하기 위한 교육적 개입 방법을 부모의 과보호적 양육태도와 분노의 관점에서 논의하고 시사점을 제시하였다. This study discovered the effect of parental overprotection on children`s anger affection in terms of trait anger and anger-out. In particular, the mediation role of the negative automatic thought between parental overprotection and anger was examined by investigating 603 middle school students. The result showed that children`s negative automatic thought was a partial mediator between parental overprotection and children`s trait anger. In addition, negative automatic thought was also identified as a partial mediator between parental overprotection and children`s anger-out. Based on the results, effective parenting method was discussed in terms of parents` overprotection influencing their children`s affective changes. Educational intervention resolving children`s problems was suggested in terms of parental overprotection and anger.

The purpose of this study was to investigate the effect of resistance training with protein supplement on the body composition and the immune response in male college student. The subjects of this study were divided two groups: resistance exercise with protein supplement group(n=7) and resistance exercise group(n=7). The body composition, growth hormone, insulin, cortisol and the immunogloblin A, G, M were not significantly different between resistance with protein supplement group and resistance training group before training. The changes of body weight(p<.05) and muscle mass(p<.001) in resistance and protein supplement group were higher than resistance group after 12weeks program. Growth hormone(p<.05), insulin(p<.01), cortisol(p<.05) significantly increased after training, but not significantly different between groups. The change of immunogloblin A, immunogloblin G, immunogloblin M and white blood cell were not significantly different after training. However, the changes of the immune globulin G(p<.05) and M(p<.05) in resistance with protein supplement group were higher than resistance group significantly. The change of insulin hormone was positively correlated with the change of the immunogloublin G(p<.05). As the results, resistance training with protein supplement showed more effective changes on the muscle mass included weight and immune response after 12weeks resistance training.

The following research, analysis about an integral part of current elementary classroom, has been done to grasp the importance of re-organization of an elementary school classroom. For the research process 11 schools, 60 classrooms have been studied to analyze the physical elements of classroom(learning tools, equipment, etc.) to provide deeper understanding on their display, and spatial arrangement, as well as characteristic of a classroom. By looking at these analyzed elements with perspective to the grade, the number of students per class, the result turned out to be uninteresting. The observation that was made by this analysis was that there are more usages of multi-purpose desk in the classroom when there are only a few numbers of students. Also the observation could be made on the classroom wall-post. Each post had a tendency to have its defined area to be posted. The analysis showed that there are total of 24 corners can be created in the classroom, also it distinctly showed that the number of corners gets changed depending on the number of students in the classroom. The 24 corners including learning tools, equipment, and posts could be sorted to a minimum of 11 areas and a maximum of 22 areas depending on the educational purpose of the corners. The current layout of these corner and area will be the primary component that will be needed for the new coming classroom. For the future progress, depending on the system of education, the following needs to be done: (1) The installation of corners in the classroom (2) A small common-lounge area between two classrooms (3) A common-corner for each grade (4) Deeper research will be required to discuss the installation of a wide-educational area.

In general, teachers' perceptions on the physical environment of elementary school are related on the quality of education and school life. But, we don't have study what teachers think of their enviroment of school. This study analyzed elementary school teachers' satisfaction with overall physical environment and their assessment of spaces with specific functions in order to understand teachers' perception of the physical environment of elementary schools. A survey questionnaire was administered to 982 homeroom teachers working at 67 elementary schools located in Seoul and Busan. Teachers' satisfaction with physical environment of school and their assessment were analyzed comparatively according to the teachers' personal attributes and school conditions. 1) Most of the surveyed teachers were satisfied with overall physical environment of the school, and assessed high the substantiality of functional spaces indoor and outdoor. By sub-factor, however, their satisfaction with work environment was lower than that with education and living environment. 2) The teachers perceived that the optimal number of classes was 30~36, and this is probably because they were relatively accustomed to large scale schools. 3) As might be expected, negative assessments were more frequent among teachers working at a large-scale school, an old school, or a school with small outdoor spaces. The results of this study show that, though partially different according to region, gender, teaching experience and school condition, teachers' satisfaction with school environment was relatively high. This suggests that elementary school teachers perceive their current school environment positively. Because they are accustomed to traditional education methods that have been maintained.

규칙적인 유산소운동이 비만 중년여성의 신체구성 및 폐기능 변화에 미치는 영향

본 연구는 12주간의 복합트레이닝 후 비만중년여성의 신체구성 및 체지방률의 변화가 폐기능의 변화에 미치는 영향을 알아보고자 실시되었다. 피험자는 체지방률이 30%이상인 비만 중년 여성 37명으로 선정하였으며, 대조군 14명과 운동군 23명으로 무선 배정하였다. 12주간의 유산소운동 프로그램은 V ˙ O2R의 60%에서 주당 3회, 하루 60분 동안 실시하였다. 12주간의 유산소운동 참여에 따른 집단과 측정시기 간 상호작용효과를 검증하기 위해 반복측정분산분석(repeated measure ANOVA)을 실시한 결과, 운동군에서 유산소운동 후 체중(p<.01), 체지방률(p<.001), WHR(p<.01)는 유의한 감소를 나타낸 반면에, FEV1/FVC(p<.001), FEF25-75%(p<.001), MVV(p<.05)는 유의한 증가를 나타내었다. 운동 후 FEV1/FVC와 FEV25~75%의 변화량은 체지방률의 변화량과 음의 상관관계를 나타내었으며, 또한 MVV의 변화량도 체중, 체지방률, WHR등의 모든 신체구성성분의 변화량과 음의 상관관계를 나타내었다. 이러한 결과는 규칙적인 유산소운동이 신체구성성분의 유의한 감소, 특히 체지방량의 감소와 함께 폐기능이 효과적으로 개선되어짐을 제시한다. The purpose of this study was to determine effects of regular aerobic exercise on body composition and pulmonary function in obese middle-aged women. Thirty seven obese women (≥30%fat) were randomly divided into control( n=14) and exercise group(n=23). Supervised exercise program for 12 weeks consisted of 60% V ˙ O2R, 3days a week, and 60minutes a day. Two-way ANOVA with repeated measures was used to analyze an interaction effect between time and group. Whereas body weight(p<.01), %fat(p<.001), and WHR(p<.01) were significant decreased, FEV1/FVC(p<.001), FEF25~75%(p<.001), and MVV(p<.05) were significant increased after exercise training. The change of FEV1/FVC and FEV25~75% was negatively associated with the change of %fat. Also, the change of MVV was negatively correlated with the change of body weight, BMI, %fat, and WHR. The results of this study suggest that regular aerobic exercise may induce a significant reduction of body composition, especially percent body fat, along with the improvement of lung function
