This study was performed to identify the tendency and benefits of outdoor recreation in rural areas. The preferences and importance of the benefits of outdoor recreation activities in rural areas were simultaneously compared and analyzed through the discussion of a four quadrants portfolio map using importance-performance analysis. The social benefits in quadrant i had the characteristics of 'sharing nice experiences with others', 'having contact/interchange with others', 'colleagueship/helping each other', 'being together with friends', and 'making new friends.' These social benefit types were perceived as very important characteristics, but the real level of achievement was rather low. Thus it seems necessary, in the process of program development, to apply the social benefit types to the characteristics of the participants. The experience of nature and relaxation benefits in quadrant ii had the characteristics of 'relaxation and recreation', 'understanding nature', 'nature experience', 'getting away from everyday life', and 'experiencing new things.' These benefits and experience of nature were regarded as very important characteristics by the participants in outdoor recreation and, at the same time, their real achievements were highly recognized, thus they seemed to be proper types for the goals involved in developing an outdoor recreation activity program in rural areas. The personal and challenge benefits in quadrant iv had the characteristics of 'training of mental ability', 'improvement of self-esteem', 'fitness', 'increase in determination', 'possible danger', 'achievement', 'excitement', and 'adventure.' These benefits had less importance to the participants, but had relatively high achievement, thus it might be important to make further suggestions for the direction of development according to the participants' tendency, seasons and facilities.

We analyzed the effects of regular Jjimjilbang (Korean sauna) exposure on the cold tolerance in young and elderly females. Subjects were young (n=7) and elderly (n=7) females who had never had Jjimjilbang exposure experience. The Jjimjil training group was exposured in the Jjimjilbang 19 times per week. Jjimjibang exposure was limited to three times per day. Jjimjil activity was taken freely. To prove the effects of the cold tolerance, subjects were exposed to cold air ($12{\pm}1^{\circ}C,\;60{\pm}10%$RH). In these conditions, subjects were exposed for 30 minutes at which time rectal temperature, skin temperatures, clothing microclimate, energy expenditure, blood pressure and subjective sensation were measured. To prove the effects of the local cold tolerance, vascular hunting reaction was observed measuring the finger skin temperature while the left middle finger tip was immersed in cold water of $0^{\circ}C$ for 30 minutes. The results are as follows. According to repeated Jjimjil exposure, rectal temperature changes, peripheral temperature and energy expenditure were increased gradually in the cold climate chamber. Blood pressure, subjective sensation and vascular hunting reactions did not show any significant difference. In conclusion, regular Jjimjilbang exposure has negative effects on the ability of the body to improve its regulation of temperature especially in cold tolerance.

Purpose: The purpose of this study was to identify differences in Health Locus of Control (HLOC), depression, wellbeing, and Health Promoting Lifestyle Profile II (HPLP) between middle aged Korean and Korean-American women. Methods: Data from 80 Korean-American women living in Los Angeles, USA and 82 Korean women living in W-city, Korea, were collected using a self administered questionnaire including items on HLOC, HPLP, a Wellbeing Index and Major Depression Inventory. Results: There were statistically significant differences between the middle aged Koreans and Korean-Americans on mean age, education, religion, and current health insurance. Significant differences were found on HLOC (F= 2.504, p=.033) and Wellbeing (F=2.451, p=.036). The results also showed significant differences on HPLP (total HPLP, F=4.655, p=.001; physical activity, F=2.967, p=.014; nutrition, F=4.250, p=.001; spiritual growth, F=4.398, p=.001; interpersonal relations, F=2.648, p=.025; and stress management, F=5.201, p<.001) using ANCOVA. However, there were no significant differences on depression, or health responsibility in HPLP between the groups. Conclusion: Understanding middle aged women's health adjustments based on their culture will enhance the ability of health professionals to provide culturally congruent care and enable middle aged women to develop healthy lifestyles.

Nowadays, recognizing human activities is an important subject; it is exploited widely and applied to many fields in real-life, especially in health care and context aware application. Research achievements are mainly focused on activities of daily living which are useful for suggesting advises to health care applications. Falling event is one of the biggest risks to the health and well-being of the elderly especially in independent living because falling accidents may be caused from heart attack. Recognizing this activity still remains in difficult research area. Many systems equipped wearable sensors have been proposed but they are not useful if users forget to wear the clothes or lack ability to adapt themselves to mobile systems without specific wearable sensors. In this paper, we develop a novel method based on analyzing the change of acceleration, orientation when the fall occurs and measure their similarity to featured fall patterns. In this study, we recruit five volunteers in our experiment including various fall categories. The results are effective for recognizing fall activity. Our system is implemented on G1 smart phone which are already plugged accelerometer and orientation sensors. The popular phone is used to get data from accelerometer and results showthe feasibility of our method and significant contribution to fall detection.

Recently, genetic engineering techniques have been used to display various heterologous peptides and proteins (enzyme, antibody, antigen, receptor and fluorescence protein, etc.) on the yeast cell surface. Living cells displaying various enzymes on their surface could be used repeatedly as 'whole cell biocatalysts' like immobilized enzymes. We constructed a yeast based whole cell biocatalyst displaying T. reesei cellobiohydrolase I (CBH I ) on the cell surface and endowed the yeast-cells with the ability to degrade cellulose. By using a cell surface engineering system based on ${\alpha}-agglutinin,$ CBH I was displayed on the cell surface as a fusion protein containing the N-terminal leader peptide encoding a Gly-Ser linker and the $Xpress^{TM}$ epitope. Localization of the fusion protein on the cell surface was confirmed by confocal microscopy. In this study, we report on the genetic immobilization of T. reesei CBH I on the S. cerevisiae and hydrolytic activity of cell surface displayed CBH I.

There are three goals of college students volunteerism. First, to act up to community needs. Second, to strengthen the academic ability and social responsibility, required skill as a citizen. Third, to provide opportunity for students quantitatively as well as qualitatively. We have many social backgrounds why we need beauty volunteerism but, if we summarize, things going like this, 1. An advanced age has come, and most of the elderly citizens are suffering from financial difficulties. 2. They have strong desire for youth regardless their physical mental aging. 3. The elderly citizens: living in solitude, the disabled, war veteran's family and low-income family. 4. The coverage of beauty is getting various and has many services areas. Up to present, beauty services are just limited to hair but skin and make-up have the various ways. This study final aims are how to do effective healthy volunteer activity and develop a program to fit according to each person's major, improve the curriculum in order to have effective volunteerism.

Bisphenol-A and related conpounds recently have been reported to be estrogenic since it has been demonstrared in laboratory stuides that they mimic the effects of estrogen. Bisphenol-A refered to as "environmental estrogen" are suspected of causing health effect in living body through disruption of endocdrine system. In this review, the occurrence, environmental fate, and biological effects of bisphenol-A are presented. To provide understanding to the potential for endocrine disruption due to environmental estrogen, the physiology of bisphenol-A mammalian and fish is also reviewed. For empty can, the migrationof bisphenol-A form food conducted epoxy coating was effected by the test conditions and it increased in order to water and 4% acetic acid. Extracts from foods packed in lacquer coated can also showed estrogenic activity. Bisphenol-A was found as a contaminant not only in the liquid food cans, but also in water autoclave in can. The used of coating certain food-packaging material may require closer scrutiny to determine when bisphenol-A contribute to advert exposure of consumers to estrogenic xenobiotics. Human breast cancer MCF cell added bisphenol-A cultivated to study the ability of bisphenol-A to elicit of bisphenol-A estrogenic bioresponse in this system. Bisphenol-A, similar to estradiol, induced PR activation in transiently transfected anterior and posterior pituitary cells.

Purpose: The purpose of this study was to examine the effect of balance taping procedures on lower back pain. Method: This study is nonequivalent control group pretest-posttest design of quasi-experimental study. From May in 2004 to July in 2004, the research was done for females who have lower back pain in Gyeonggi province. Experimental group was 37, and control group was 36. The degree of lower back pain and that of the pain on activity of daily living(ADL) were each measured two times. Result: In the experimental group, the lower back pain score before taping was 6.38, that of 1 hour after the taping applied was 3.27. The lower back pain score of experimental group was significant statistically decreased and that of control group was almost not changed. Moreover, the pain score on ADL was statistically decreased in experimental group. Therefore balance taping is effective to reduce lower back pain and to improve ability of ADL. Conclusion: This study supports that balance taping may benefit individuals with lower back pain and balance taping therapy can be used as an independent nursing intervention. However, a larger study is in need to provide definite evidence and to determine long-term effects.
