Purpose : The purpose of this study was to examine the effect of the self- efficacy, group cohesion and family support on adherence of aquatic exercise in arthritis patients. Method : The Subjects were 30 patients with arthritis who had participated in the 6-week aquatic exercise programs of Korean Rheumatology Health Professionals Society. All subjects were interviewed from November to December, 2001(1st) and Feburary, 2002(2nd) using a structured questionnaire which was composed of 42 items. SPSS Win 10.0 was used for data analysis. Results : Ten out of thirty were adherer who were keeping aquatic exercise for three months since they completed 6-week aquatic exercise program. The major reasons of adherence were affectional reasons and general condition improvement on the first month. The reasons of 3-month adherence were improvement of arthritis symptoms, affectional improvement, expectations, general condition improvement and group activity. The major reasons of drop out were environment factors and physical factors. The environmental reason were time shortage, economic problem and long distance. And the physical factor were cold, pain and other health problem. The scores of self-efficacy were decreased from 528.00 to 476.00 within 3 months after compeleting aquatic exercise program and that was statistically significant(p=.029). But there were no statistically differences in group cohesion and family support. There was a significant positive correlation between exercise adherence and self-efficacy. Factors influencing the exercise adherence was self-efficacy which accounted for 23% of the variance in the exercise adherence. Conclusion : In conclusion, self-efficacy is a significant variable in the exercise adherence and changes within 3 month after completing aquatic exercise program. The results of this study suggested that the strategy for maintaining self-efficacy should be developed.

Physical activity has been effective in enhancing quality of life and physical fitness of older adults over relatively short periods of time. However, little is known about the Yoga-based exercise program on physiological changes and physical fitness with psychological variables in elderly women. The purpose of this study is to investigate the effect of Yoga- based exercise program on physiological, psychological factors and physical fitness in elderly women. Forty-four elders were recruited from the public health center. They were divided into exercise training group(n=22) and control group(n=22). The training group participating in 10 weeks of Yoga-based exercise program. Data was analyzed with descriptive statistics, the chi-square test, Fisher's Extract test, and ANCOVA to evaluate body fat, spine ROM, blood pressure, cholesterol, depression, life satisfaction, ADL and physical fitness. There was a significant improvement in blood pressure, total cholesterol, precent of body fat, physiological function, depression, life satisfaction, ADL and physical fitness in the exercise training group than that of the control group.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

Human breast milk (HBM) provides neonates with indispensable nutrition. The present study evaluated the anti-cancer activity of diluted and pasteurized early HBM (< 6 weeks' lactation) on human breast cancer cell lines. The cell lines MCF7 and MDA-MB231 were exposed to 1 % HBM from the 1st, 3rd, and 6th weeks of lactation and exhibited reduced proliferation rates. As controls, breast cell lines (293T and MCF-10A), breast cancer cell lines (MCF-7 and MDA-MB-231), and $CD133^{hi}CXCR4^{hi}ALDH1^{hi}$ patient-derived human cancer stem-like cells (KU-CSLCs) were treated with prominent milk proteins ${\beta}$-casein, ${\kappa}$-casein, and lactoferrin at varying doses (10, 50, and $100{\mu}g$) for 24 or 48 hrs. The impact of these proteins on cell proliferation was investigated. Breast cancer cell lines treated with ${\kappa}$-casein and lactoferrin exhibited significantly reduced viability, in both a dose- and time-dependent manner. Interestingly, ${\kappa}$-casein selectively impacted only cancer (but not normal breast) cell lines, particularly the more malignant cell line. However, ${\beta}$-casein-exposed human breast cancer cell lines exhibited a significantly higher proliferation rate. Thus, ${\kappa}$-casein and lactoferrin appear to exert selective anti-cancer activities. Further studies are warranted to determine the mechanisms underlying ${\kappa}$-casein- and lactoferrin-mediated cancer cell-selective cytotoxic effects.

Since students of the College of Maritime Sciences will become professionals contributing to the development of the Korean shipping industry after graduation, they are required to successfully complete school life including theoretical and practical curriculum with health promotion behavior. The purpose of this study was to investigate the factors influencing health promotion behavior by students of the College of Maritime Science in order to collect basic data through a survey for the development of health promotion programs. Health promotion behavior by students of the College of Maritime Sciences was less frequent than by other college students, and the levels of health promotion behavior sub-domains were lower in order of interpersonal relations, spiritual growth, stress management, nutrition, physical activity, and health responsibility. The most influential factors for health promotion behavior were learner participation, health promotion self-efficacy, self-esteem, and social support. It is necessary to develop a differentiated health promotion program considering the characteristics of students and to apply it systematically from the time of admission to improve health promotion behavior by students of the College of Maritime Sciences.

Light is a major external environmental factor that influences the circadian rhythm of photosynthetic organisms and various physiological phenomena, such as growth, maturation, and behavior. The number of light-reaching organisms changes depending on the season and atmospheric conditions, and the intensity and wavelength of light differ depending on the organisms inhabiting the environment. Altered light changes the circadian rhythm of fish, which is controlled by clock genes, such as period 2 (Per2), cryptochrome 1 (Cry1), and melatonin. In this study, we set the zeitgeber time (ZT; 14 light-10 dark, LD) based on the actual sunrise and sunset times and examined Per2 and Cry1 activities, levels of aralkylamine N-acetyltransferase (AANAT), and melatonin in Pholis nebulosa, a drifting seaweed species exposed to irregular light. Per2 and Cry1 levels increased during the daytime and decreased after sunset. The AANAT levels decreased during the daytime and increased during the night. Melatonin concentration was highest around midnight (ZT21, 23:30), but exhibited similar concentrations during the daytime. While the activity of Per2, Cry1, and AANAT levels exhibited a typical circadian rhythm observed in most vertebrates, melatonin concentrations did not show a significant difference between the daytime and nighttime. These findings provide insights into the circadian rhythm patterns of organisms exposed to irregular light environments, such as P. nebulosa, which differ from those of typical fish species.

Peroxisome proliferatorr-activated receptor-gamma $(PPAR{\gamma})$ must form a heterodimer with the retinoid-X receptor (RXR) to bind DNA, and its transcriptional activity is thought to be maximized by ligands specific for either receptor. Activated $(PPAR{\gamma})$ and $(PPAR{\gamma})$ ligands may influence tumor growth through regulation of the tumor suppressor PTEN. Our aim in this study was to determine whether co-stimulation with the $(PPAR{\gamma})$ ligand, ciglitazone, and RXR ligand can synergistically upregulate PTEN in human acute promyelocytic leukemia (APL) cells and consequently potentate the inhibition of cell growth and cell cycle progression of these cells. Human leukemia cell line, HL-60 cells were exposed to all-trans-retinol and ciglutazone. The PTEN expression was measured as the level of PTEN mRNA expression by RT-PCR and as the level of PTEN expression by western blot analysis. Cell cycle analysis was carried out by a propidium iodide (PI) staining method and analyzed with a FACScan. The $(PPAR{\gamma})$ ligand, ciglitazone, and the RXR ligand, retinoic acid, upregulated PTEN expression by HL-60 cells in time- and dose-dependent manners, respectively. This was significantly enhanced by a combination of both ciglitazone and retinoic acid. Moreover, these compounds synergistically induced arrests of both cell growth and the $G_l$ phase of the cell cycle. Thus, the activation of the $(PPAR{\gamma})$:RXR heterodimer may represent a regulatory pathway for human leukemia cells and there may be important roles for $(PPAR{\gamma})$ and RXR ligands in prophylactic and therapeutic approaches fur controlling leukemia through the upregulation of PTEN.
