Now in order to overcome the weakest points of the rural areas of the city of Kimje and, transform them into rural cultural villages which have local governing systems suitable to new localization age and activate this plan, we selected Daesan Village as a model village which had shown a lot of potentials in the basic research and studied it dividing it into the former part and the latter part. We studied Daesan village in the former part focusing on state analysis and basic ideas and in the latter part focusing on master plan and detail planning. We can summarize the conclusion like the followings. 1. Daesan Village located 8 kilometer away from the downtown Kimje and the city of Iksan respectably has comparatively good environment of good sunny place as an open field whose surrounding configuration of the ground consists of farming lands and low hills in front and rear. It has 38 farming households in all. 2. Human environment(인문환경); the village road whose width is about 4 meters is forming a flow system forking off into three. There is a route bus which operates three times a day even into the inside of the village. The main sources of revenue are vegetables in facilities, fruits and floriculture. Their average revenue is about 10.5 million won. 3. Here in DaeSan Village a legend dealing with Teasan literally meaning a big mountain consist of th village's tradition and you can see the tombs of a very faithful son and Anwi an army general in the age of the Japanese Invasion of Korea of 1592 to 1598 inside the village. 4. 85 out of the eitire population 141 whose age are over 20 showed very positive attitudes in a questionnaire about, making the village a cultural one and its development. 5. The basic of planned ideas is to increase the revenue of the farming household by making the village a professional farming one which has a state-of the-art production facility and agricultural technique. It is to make the village the one where people can enjoy the sense of the rural life and the farmer can enjoy their lives through consumptive and consistant leisure and resting activities. 6. We are planning to make entrance space, life space, rest and sport space, and cultural space considering the characteristics of the village and the demand of the resident. We are also planning to make tile entire city of Kimje an information transmitting base in short and long term perspectives. 7. DaeSan Village was planned as a place where tradition and the future exist together. On the basis of this concept we planned future programs for Daesan Village and in the latter part of the study master plans and detail plans will be continued.the regional agricultural condition. The development permissions were only during the period of restricted to use ($1979.12{\sim}1993.11$). We propose that the authority of development permission should be given to the local autonomy government, because the local government has the knowledge of its individual agricultural conditions.

Playground is frequently used for physical and sports activity by students as well as by common people, which is constructed with various cover materials on the ground. This research surveyed the surface temperature in Kyungpook National University Sangju campus playground which is covered with various cover materials [bare field, zoysiagrass (Zoysia japonica) turf field, urethane track, concrete field, epoxy field and artificial turf field] in Sangju, Gyeongsangbukdo, Korea. Temperature was measured 4 times per day at 09:00, 12:00, 15:00, and 18:00 from May to October 2014 in surface and 1 m height above the ground. Surface temperature was different, depending on cover materials and survey time. Bare field and zoysiagrass turf field was lower surface temperature than other sites. Higher surface temperature site was different depending on survey time. Urethane track and artificial turf field was hotter than other sites at 12 and 15 hours, however concrete and epoxy field was hot at 18 hours. One meter above ground temperature was the highest in artificial turf field except at 18 hours. So natural turf, zoysiagrass playground will increase the athletic performance by reduce the surface and above ground temperature.

Lots of interdisciplinary studies for fusion of high technologes and the other areas of research had been tried in these days. In sports training area, high technologies like a vital sign sensor or an accelerometer were adopted as training tools to improve the performance of the sports players. The purpose of this study is finding the proper locations on the human body for attaching the motion sensors in order to develop a smart sportswear which could be helpful in training players. The rowing was selected as a subject sport as lots of movements of the joint on human body could be seen in rowing motions. The players of rowing could be devided into two weight divisions, the lightweight and the heavyweight. In this study, the change rates of distance between markers on human skin as the players moved were took on the back, the elbow, the hip and the knee area on human body by 3D motion capturing system. The distances between markers and the differences between the lightweight and heavyweight were analyzed. Finally, this study provided the guide lines for designing a motion sensing smart sportswear.

The purpose of this study was empirically to reveal the effects of emotional labor and job burnout of the ski resort workers on service level. For the study, a survey of 215 people working in domestic ski resorts was conducted. Emotional labor was composed of two sub-factors: surface acting and deep acting. Service level was composed of three sub-factors: tangibles, responsiveness, endeavor. The following results were obtained by confirmatory factor analysis, reliability analysis, correlation analysis, regression analysis. First, in emotional labor which ski resort worker perceived, surface acting had a positive effect on job burnout, while deep acting had a negative effect on it. Second, surface acting had a positive effect on tangibles and responsiveness of service level and deep acting had a positive effect on tangibles, responsiveness and endeavor of service level. Third, job burnout which ski resort worker perceived had a negative effect on tangibles, responsiveness and endeavor of service level. This study suggested that implications and limitations of the relationship between outcomes and emotional labor which people working at sport organizations such as a ski resort have experienced.

The purpose of this study is to evaluate the different type of exercise training on the changes of blood variables and leptin in SD rats. For this study, SD rats were divided into three groups: control group (CG: n=10), swim trained group (SG: n=10), and treadmill trained group (TG: n=10). The animals were housed in a pathogen-free animal facility ($22-24^{\circ}C$, 50-60% relative humidity, 08:00-20:00 lighting hours) at D university animal center, Pusan, Korea). Food and water were available ad libitum. The trained rats underwent a 8-wk endurance swim training (5 times/wk) in water at $26-29^{\circ}C$ (SG) and treadmill training (5 times/wk) in DAEJONG treadmill for 60 min. All data were expressed as mean and standard deviation by using SPSS package program (ver 10.0). The result through the statistical analysis of this data were summarized as follows: 1. In the weight changes, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest weight than the other groups. 2. In the epididymal & perirenal adipose tissue levels, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest adipose tissue levels than the other groups. 3. In the triglyceride changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest triglyceride levels than the other groups. 4. In the insulin hormone, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest insulin levels than the other groups. 5. In the leptin changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG was the lowest than the other groups. Based on the results, Regular swim and treadmill training decrease body weight, epididymal & perirenal adipose tissue levels significantly, this is caused but by decreased triglycerides, insulin, and leptin hormone levels not by the other factors. Regular treadmill training decreased insulin hormone levels compare to swim training, however there was no direct insulin effect on the weight changes. and it might be the direct effect of leptin hormones.

Exercise increases the expression and interaction of major neurotrophic factors such as brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) at both central and peripheral tissues, which contributes to improved brain and neural plasticity and cognitive function. Previous findings have been to understand the effect of light or moderate intensity aerobic exercise on neurotrophic factors and cognitive function, not that of high intensity aerobic exercise. However, recent findings suggest that high intensity interval training is a safe, less time-consuming, efficient way to improve cardiorespiratory fitness and weight control, thus American College of Sport Medicine (ACSM)’s guidelines for exercise prescription for various adult populations also recommend the application of high intensity interval training to promote their overall health. High intensity interval training also enhances the expression of BDNF, IGF-1, and VEGF at the brain and peripheral tissues, which improves cognitive function. Increased frequency of intermittent hypoxia and increased usage of lactate as a supplementary metabolic resource at the brain and neural components are considered a putative physiological mechanism by which high intensity interval training improves neurotrophic factors and cognitive function. Therefore, future studies are required to understand how increased hypoxia and lactate usage leads to the improvement of neurotrophic factors and what the related biological mechanisms are. In addition, by comparing with the iso-caloric moderate continuous exercise, the superiority of high intensity interval training on the expression of neurotrophic factors and cognitive function should be demonstrated by associated future studies.

Exercise can favorably influence brain plasticity by facilitating neurogeneration, neuroadaptivity, and neuroprotection. Aerobic exercise has been reported to change brain nerve growth factors (growth hormone, insulin like factor-1, estrogen and serotonin). The purpose of this study was to demonstrate the effects of aerobic exercise for 12 weeks on brain nerve growth factors in girls. Fourteen female participants in elementary school grades 1 through 3 were randomly allocated to the exercise group (EG, n=6) and control group (CG, n=8). The EG participated in 60 minutes of modified ballet exercise as aerobic training three days a week for 12 weeks. Based on comparison between groups by two-way ANOVA with repeated measures, aerobic exercise program participants experienced decreased weight (p<0.01), BMI (p<0.01), fat mass (p<0.001), fat percent (p<0.001) and increased LBM (lean body mass) percent (p<0.001). In addition, we detected that aerobic exercise decreased the level of serotonin (p<0.05) and increased the level of GH (p<0.05) and IGF-1 (p<0.05). These findings suggest that aerobic exercise programs can be an efficient intervention to change body composition, alleviate central fatigue, improve brain function, and induce brain cell proliferation in girls.
