The purpose of this study was to investigate the environmental factors having a influence on the preference of residential district and to furnish basic information for the successful settlement. For the purpose, residential preference and values on the residential district were estimated according to the housing life cycle. Data were collected through questionnaires designed for this study, and the objects of this research were university students. To analyze the data were used spsswin program. The major results were as follows. 1. According to the housing life cycle, there were significant differences in the preference of the residential district, living area and housing type in the future. Metropolitan and seoul, residential area and commercial area, apartment, office-hotel and row house were preferred in the housing formative. In the stable period, seoul and metropolitan, tower apartment, residential area were preferred. But in the housing reductive period, they preferred a green zone in the rural, the detached house. 2. The degree of consideration of living convenience facilities was high in the housing formative period. Both education-leisure, business facilities and marketing facilities were highly valuated in the housing stable period. But the value of welfare facilities was high in the housing reductive period. 3. The 4 dimensions of values in environmental conditions were extracted through factor analysis. They were natural, human, social, and economic factors. According to the housing life cycle, there were significant differences in factors being considered as the environmental conditions. The values of human and economic factors were high in the housing formative and stable period. Natural factor were highly considered in the housing reductive period.

지금까지 국내에서 제작된 요트는 선체의 재질이 FRP로 제작되어 왔으나 FRP는 환경오염 및 해양안전에 관한 법규 규제가 강화되고 있는 국제사회의 인식에 따라 중소형 조선소를 중심으로 강철 재료나 알루미늄 재료들 사용한 선박건조로 변화하고 있는 실정이다. 강선요트의 구조상 강선재료를 주로 사용함으로서 여러 가지 강도적인 측면에 대한 검토가 필요하지만, 소형선박이므로 종강도, 횡강도 부분은 규정에서의 허용 응력치에 안전율(Safe Factor)만을 주어서 설계를 하여도 충분히 안정된 구조를 이를 수가 있다. 그러나, 소형선박에서 가장 문제시되는 것은 국부강도(Local Strength)의 평가이다. 본 구조해석에서는 선수에 작용하는 슬래밍 동작하중 및 선수충격에 의한 선수부의 손상 여부와 선수부의 국부강도 만족 여부를 확인하고, 기관받침(Engine bed) 부분에서의 중량하중과 횡파하중에 대한 검토를 수행하였다.

Extreme sports refers to sports activities with a high level of inherent danger, such as extreme skiing, snow-boarding, mountain biking, motocross bicycling, aggressive in-line skating, wake-boarding, and paragliding. This study investigates the characteristics of extreme sports participants as group identities through an examination of the differences between extreme sports participants and traditional sports groups in lifestyle and sportswear benefits sought. We composed a total 108-item lifestyle profiles characterized by six lifestyle dimensions (dress, diet, home, recreation, consumption, and sense of values); in addition, we developed 32 items for sportswear benefits sought. The surveys targeted 422 sports participants living in Korea (216 men and 206 women, aged 15-23): 119 extreme sports participants and 303 traditional sports participants. All items were evaluated on a 5-point Likert scale, and SPSS 17.0. was used for data analysis. Exploratory factor analysis was conducted to confirm the substructure of each lifestyle dimension and sportswear benefits sought. The results of the factor analysis on each lifestyle dimension are as follows: 5 factors in dress dimension, 4 in diet, 3 in home, 6 in recreation, 5 in consumption, and 6 in sense of values. Six factors of sportswear benefit sought were identified. A t-test revealed that there were significant differences between the two groups in lifestyle dimensions and sportswear benefits sought. This study reveals that the lifestyle characteristics of extreme sports participants are more likely than traditional sports group to be more self-expressive, more distinctive, more fashion-oriented, more conspicuous, and more brand-oriented, while preferring more active sports, more dynamic leisure, and a more sensible life. Another finding is that extreme sports participants seek the distinctive, conspicuous, and latest sportswear benefits.

We investigated the effect of moderate- and high-intensity resistance training on hippocampal neurotrophic factors and peripheral CCL11 levels in high-fat diet (HFD)-induced obese mice. C57/black male mice received a 4 weeks diet of normal (control, CON; n = 9) or a high-fat diet (HF; n = 27) to induce obesity. Thereafter, the HF group was subdivided equally into the HF, HF + moderate-intensity exercise (HFME), and HF + high-intensity exercise (HFHE) groups (n = 9, respectively), and mice were subjected to ladder-climbing exercise for 8 weeks. The hippocampal brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) levels were significantly lower in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly higher than in the HF group (p < 0.05). The peripheral CCL11 levels were significantly higher in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly lower than in the HF group (p < 0.05). However, there was no significant difference according to the exercise intensity among the groups. Collectively, these results suggest that obesity can induce down-regulation of neurotrophic factors and inhibition of neurogenesis. In contrast, regardless of exercise intensity, resistance training may have a positive effect on improving brain function by inducing increased expression of neurotrophic factors.

UV radiation is the most dangerous stress factor among permanent environmental impacts on human skin. Consequences of UV exposure are aberrant tissue architecture, alterations in skin cells including functional changes. Nowadays new kinds of outdoor leisure-time activities and changing environmental conditions make the question of sun protection more important than ever. It is necessary to recognize that self-confident consumers do not consider to change their way of life, they demand modern solutions on the basis of new scientific developments. In the past one fundamental principle of cosmetics was the use of physical and organic filter systems against damaging UV-rays. Today new research results demonstrate that natural protecting cell mechanisms can be activated. Suitable biological actives strongly support the protection function not from the surface but from the inside of the cell. A soy seed preparation (SSP) was proven to stimulate natural skin protective functions. The major functions are an increased energy level and the prevention of DNA damage. These functions can I be defined as biological UV protection. The tumor suppressor protein p53 plays a key role in the regulation of DNA repair. p53 must be transferred into the phosphorylated form to work as transcription factor for genes which are regulating the cell cycle or organizing DNA repair. A pretreatment with SSP increases the phosphorylation rate of p53 of chronically UV-irradiated human keratinocytes significantly. According to the same test procedure SSP induces a dramatic increase in the expression of the tumor suppressor protein p14$^{ARF}$ that is supporting the p53 activity by blocking the antagonist of p53, the oncoprotein Mdm2. Mdm2, a ubiquitin E3-ligase, downregulates p53 and at the same time it prevents phosphorylation of p53. The positive influence of the tumor suppressor proteins explains the stimulation of DNA repair and prevention of sunburn cell formation by SSP, which was proven in cell culture experiments. In vivo the increased skin tolerance against UV irradiation by SSP could be confirmed too. We have assumed, that an increased repair potential provides full cell functionality.y.

This study was conducted to investigate the effect of a 24-week combined exercise training program in older women with hypertension. Women with hypertension who were 70 years and older were randomized into two groups: combined exercise group (CE; n = 15) and a control group (n = 15). The CE group performed a combined exercise training program four times per week for 24 weeks and the control group did not. Five factors, including body composition (percent body fat and skeletal muscle mass), health-related physical fitness, adipocytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-α]), kidney risk factors (glomerular filtration rate [GFR] and cystatin C), and systolic and diastolic blood pressure were measured before and after the program. The findings showed that total muscle mass, health-related physical fitness factors, and GFR increased significantly in the CE group compared to those in the control. Additionally, systolic and diastolic blood pressure and IL-6, TNF-α, and cystatin C levels in the CE group decreased significantly after the intervention. In contrast, total muscle mass decreased significantly and blood pressure remained unchanged in the control group. These results suggest that CE training may positively impact circulating levels of adipocytokines and cystatin C and improve physical fitness levels in elderly women with hypertension. Therefore, CE training helps to prevent renal disease and improve health-related physical fitness, eventually leading to a better quality of life.
