Purpose: The purpose of the study was to compare community residents' perceptions, participation, satisfaction, and behavioral changes between a health promotion demonstration health center and general health center. Method: The design of the study was ex-post facto that compared community residents in demonstration health centers and general health centers. The sample included 2,261 community residents who were conveniently selected from demonstration (792 participants) and general health centers (1,496 participants). Result: The results of the study were as follows: 1) Perception and participation rates of exercise, nutrition, and hypertension management programs were significantly higher in the participants of demonstration health centers than those of general health centers.; 2) Satisfaction rates of all programs except the smoking cessation program were significantly higher in the participants of demonstration health centers than those of general health centers. However, only the exercise rate among risk behaviors of participants was significantly higher in demonstration health centers than general health centers. Conclusion: Systematic efforts for health promotion were effective not only in improving the community's awareness, participation, and satisfaction of the program, but also in changing health behaviors. This evidence should be used to foster and disseminate health promotion programs toother health centers to improve community residents' health status and quality of life.

To understand the molecular mechanism involved in the survivability of cold-tolerant lactic acid bacteria was of great significance in food processing, since these bacteria play a key role in a variety of low-temperature fermented foods. In this study, the cold-stress response of probiotic Lactobacillus plantarum K25 isolated from Tibetan kefir grains was analyzed by iTRAQ proteomic method. By comparing differentially expressed (DE) protein profiles of the strain incubated at 10℃ and 37℃, 506 DE proteins were identified. The DE proteins involved in carbohydrate, amino acid and fatty acid biosynthesis and metabolism were significantly down-regulated, leading to a specific energy conservation survival mode. The DE proteins related to DNA repair, transcription and translation were up-regulated, implicating change of gene expression and more protein biosynthesis needed in response to cold stress. In addition, two-component system, quorum sensing and ABC (ATP-binding cassette) transporters also participated in cell cold-adaptation process. These findings provide novel insight into the cold-resistance mechanism in L. plantarum with potential application in low temperature fermented or preserved foods.

Purpose : The purpose of this study is to understand the experiences of nursing students in clinical practice at a public health center through their self- reflections. Subjects : The 110 students in the 3rd year, practice at two public health centers in city P and city K. From the110, 53 male and female university students who practice in city K were selected to participate : 11males (20.8 %) and 42 females (79.2 %). Methods : The data analyzed were the self-reflections regarding the clinical practice. Results : These data indicate that : most of the participants now believe that public health centers provide many more services to the community than they previously knew about. They rate the public health center's programs highly, and want to be community health nurses. For the first time, they realize that the work of public health nurses is very important. In particular they note that their emotions while at the public health center differ significantly from when they work at the other. The environment in the public health center makes them feel more comfortable and less stressed. Generally, they are satisfied with their practice at the public health center. Conclusion : On the basis of these findings, the following recommendations can be made. Experience at public health centers is an important part of nursing students' education. I suggest that research on nursing students' experiences while practicing at the public health center should expand to include research methods other than the analysis of their reflection journals, In addition a follow-up study of experiences while practicing at the public health center should be attempted of self-reflections.

Purpose: This study was a part of preliminary survey for establishing Korean HPS(Health Promoting School) model which was originally suggested by WHO. Methods: Three elementary and middle schools were sampled in urban and rural area across three level of social-economic status, and survey was conducted on one class in each grade by random selection. To measure mental health and social and familial factors, self-esteem scale, self-efficacy scale, depression scale, family cohesion scale, parent-child communication scale, adolescent's mental health and problem behavior questionnaire(AMPQ), and other question items about family status and economic level were conducted. Students' mental health level was compared by region, sex, grade, and other familial and economic factors. Results: Familial and social factors such as economical and educational level of parents, number of family members were different between rural and urban area. Also, students of rural area got lower scores at self-esteem, self-efficacy, but higher scores at extroverted problem behavior than their urban counterparts. In pre-school students, high grade students' self-esteem, and family cohesion scores were lower than low grade students. And sexual differences were found across problem behavior domain and region in middle school students. Especially, the students of single-parent family and lower economic family got insistently low scores at various mental health related scales. Conclusion: These results should be considered, when the HPS model is designed and applied in Korea.

The inhibitory effects of (1R, 9S)- and (1S, 9R)-enantiomers of $\beta$-hydrastine (BHS) on dopamine biosynthesis in PC12 cells were investigated. (1R, 9S)-BHS decreased the intracellular dopamine content with the $IC_{50}$ value of 14.3 $\mu\textrm{M}$ at 24 h, but (1S, 9R)-BHS did not. In these conditions, (1R, 9S)-BHS inhibited TH activity mainly in a concentration-dependent manner(33％ inhibition at 20 $\mu\textrm{M}$) and decreased TH mRNA level. (omitted)

Objectives: This study was performed in order to determine airborne fungi levels in homes and find related factors that may affect airborne fungi concentration. Methods: Fifty homes were study subjects for measuring airborne fungi. For sampling airborne fungi, the impaction method on agar plates was used and samples were counted as colony forming units per cubic meter of air ($CFU/m^3$). In addition, information regarding housing characteristics and atopic disease in each home were collected via questionnaire. Results: The geometric means (GM) of airborne fungi concentrations in fifty living rooms and bedrooms were 68.03 and 62.93 $CFU/m^3$, respectively. The GM of airborne fungi concentration in atopy homes was 78.42 $CFU/m^3$. This was higher than non-atopy homes' 54.34 $CFU/m^3$ (p-value=0.051). In the results of the multiple regression analysis, outdoor airborne fungal concentration proved a strong effective factor on indoor airborne fungal concentration. Also, construction year, floor area of house, indoor smoking and frequency of ventilation were factors that showed a significant association with indoor airborne fungi concentration. Conclusions: The results of this study show that some housing and living characteristics may affect the development and increase of airborne fungi. In addition, exposure to airborne fungi may be a risk factor for the prevalence of childhood atopic diseases.
