Purpose: This study is intended to compare musculoskeletal characteristics and Bone Mineral Density (BMD)-related factors between male and female students in a university. Methods: This descriptive study used self-report questionnaires and physical measurements to collect data. Subjects were 64 male and 67 female university students. The questionnaires asked BMD-related factors such as diet, exercise, mental health, and lifestyle. Data were analyzed using descriptive statistics, t-test, $x^2$-test, Fisher's exact test and correlation analysis. Results: The male group showed better back strength, balance, endurance, physical activity, and musculoskeletal health management than the female group. Depression and smoking rates were higher in the male group than in the female group. No difference was found in diet between the two groups. Conclusion: The results suggest to develop gender-specific strategies to increase BMD in university students.

We selected 113 subjects (male:59, female:54) in 20 to 29 age and observed the skin color difference between female and male. Also we measured the minimal persistent pigment darkening dose (MPPD) in same subjects. The skin colors of upper inner arm and back were measured with chromameter (CR10, Minolta, Japan) which represents skin color as $L^{*}$, $a^{*}$, and $b^{*}$ in value. MPPD was measured with solar simulator multi-port 601(Solarlight Co. USA). All statistical analysis was performed on the computer software package SPSS 8.0. The skin colors between male and female was significant difference in back and upper inner arm. There was significant difference of skin colors between back and upper inner arm in both male and female. There was no relationship existed between the values of MPPD and skin color ( $L^{*}$ $a^{*}$ $b^{*}$) of back in both male and female. As a result of survey, we knew that there was apparent difference of skin color between back and upper inner arm due to gender. Also we hope these data will be helpful to study on the correlation of the pigmentation index and skin color.(omitted)omitted)ted)

Purpose: The purpose of this study was to investigate gender role identity and health behavior and to explore the relationship between gender role identity and health behavior among university student. Method: Participants were 245 university students who lived in Daegu. Each participant was administered the KGRII (Korean Gender Role Identity Inventory), and Healthy Life Style: A self-test provided by ODDHP National Health Information Center. The collected data was analyzed using descriptive statistics, t-test, ANOVA, ${\chi}^2$-test with SPSS 11.0 PC Program. Result: 1. As a result of health behavior level, male students had more health risk behavior problems than female students in smoking(p=.00) and drinking (p=.03). Female students had more health risk behavior problems than male students in exercise and physical activity(p=.00). 2. For female students, feminity type (29.3%) was most common, subjects of undifferentiated type was 26.4%. For male students, masculinity type(32.4%) was most prevalent, and androgenic type was 31.4%. 3. Androginy typed group had more healthy behavior compared with other gender role identity typed group. In contrast, undifferentiated typed group had more high risk behavior compared with other typed group for all of health behavior. Conclusion: These results suggest that gender role identity is a stronger predictor of heath related variable than is sex of subject. Therefore effect methods to develop health promotion program should consider not only sex difference but gender role identity.

The incubation time required for hatching of O. ocellatus were investigated through the processes of egg and embryonic developments by the dissecting microscopic and visual observations. And differences in ecological characteristics of the plankton mode of life or the benthic mode of life according to total numbers of the suckers on each short arm of the hatched juvenile larvae of O. ocellatus were studied by comparisons with other octopodidae species. Compared with the recent a few results reported by other researchers associated with the incubation time required for hatching by female adult mother of O. minor (73-90 days after spawning at $20.9-21.5^{\circ}C$ ranges), in this study, the incubation time required for hatching by female adult mother of O. ocellatus was 56-57 days after spawning at $11.0-20.4^{\circ}C$. Therefore, the incubation time required for hatching by female adult mother varied with Octopodidae species. In this studies, each ovarian egg laid by a female was connected to an egg string attaching to the surface of the wall or bottom of vacunt shell of Rapana venosa. Egg and embryonic developments of this species were studied in the indoor aquaria, in the specific gravity ranging 1.024-1.025. the hatched juvenile of O. ocellatus is 10.3 mm in the mean total length and 4.5 mm in mantle length, and each of its short arms has 18-20 suckers. The just hatched juvenile larvae of O. ocellatus enter the benthic mode of life (benthic larval stage) after hatching. In particular, regarding differences in ecological characteristics of the mode of life according to total numbers of the suckers, O. vulgaris may not need to have many suckers because they enter the planktonic mode of life after hatching, however O. ocellatus may need to have many suckers, because they should adapt to the benthic mode of life. And also the just hatched juvenile larvae of O. minor (bearing many suckers more than O. ocellatus) enter the benthic mode of life (benthic larval stage) after hatching. Therefore, the total number of the suckers on each short arm of the hatched juvenile larvae can be used for determining whether an octopus species has planktonic larval stages or benthic larval stage (benthic mode of life). In particular, The intracohort cannibalism phenomena appeared at the hatched juvenile larval stage because the larval stage of O. ocellatus and O. minor enter into the benthic larval stage in the early stage, unlike entering into the plaktonic larval stage in other Octopus species such as O. vulgaris: at this time, the early hatched larvae fed the late hatched larvae (they are the same species and almost same ages). Therefore, the intracohort cannibalism pheneomena occur in the just hatched juvenile stage of only O. ocellatus and O. minor.

Cardiovascular diseases are the leading cause of death and disability in Korea. Their risk factors can be classified as either modifiable or nonmodifiable and among modifiable factors are high bood pressure, elevated blood cholesterol, obesity and cigarette smoking. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in a rural community and to get basic data for the development of a community-based rick reduction intervention program. Evaluation involved population-based, cross-sectional samples of adult residents in a rurual community. We measured blood pressure, body fat percent by bioelectric impedance fatness analyzer and serum cholesterol and interviewed adult residents over 20-year-old age. Blood pressure was checked twice and hypertension was classified by the sixth report of the Joint National Committee on Detection. Evaluation, and Treatment of High Blood Pressure. The Cutpoints for high blood cholesterol was used National Cholesterol Treatment Guidelines and those for obesity was 25% in male. 30% in female. The results were as follows: 1. Prevalence of definitive hypertension was 59.7% in males and 54.4% in female. 2. Prevalence of hypercholesterolemia was 14.3% in male and 18.2% in female. 3. Prevalence of obese was 10.7% in male and 41.1% in female. 4. Among definitive hypertension, hypercholesterolemia, and obesity 52.1% possessed one risk factor, 12.6% two risk factors and 2.5% three risk factors in males. In females 41.4% possessed one risk factor and 27.6%. 5.7% respectively. 5. The smoking rate was 65.8% in males and 5.2% in females. Our results are used effectively for the community-based intervention towards cardiovascukr diseases risk reduction. However, because of limitations in our study design, further datas are needed including other risk factors and in-person clinical datas.

Purpose: This study investigated the prevalence of hypertension, explored sleep duration, and examined the related factors to hypertension in Korean middle-aged adults. Methods: Using raw data from the Korean National Health and Nutritional Examination Survey (KNHANES) conducted from 2008 to 2010, a secondary analysis was performed with data from 13,230 adults aged 30~64 years. ${\chi}^2$-test and multiple logistic regressions was used for the data analysis. Results: The prevalence of hypertension among Korean middle-aged adults was 21.8% and 40.3% among participants reported that their average sleep duration was below six hours a night. Risk factors for hypertension include: female (the odds ratio (OR) 1.66 for male), 50~64 years age group (OR 3.66 for 30~49 years age group), education level of elementary school (OR 1.84 for university level), low household income (OR 1.27 for upper), obesity (OR 2.41), high risk drinking (OR 1.64), and sleep duration${\leq}6$ hrs (OR 1.16 for 8 hrs of sleep). Conclusion: High risk population of hypertension could be male, aged, low education, and low income. Obesity, high risk drinking, and short sleep duration should be considered as risk factors for hypertension. Interventions for obesity management, adequate alcohol drinking and sleep duration could be considered for preventing hypertension.

The purpose of study was to develop and validate Korean Sleep Scale A which can be easily administrated by nurses for a wide range of adult subjects. Dimensions of sleep concept were derived by literature review. Previously developed sleep sclaes were also analyzed in order to develop scale items. The Korean sleep scale A was structured as a 15 item, 4 point likert type scale. The Scale was tested an 298 female and male adult subjects after pilottest and content validation. The results showed reliability by internal consistency of Cronbach's α=.75 Construct validity was tested by factor analysis and known group technique. Factor analysis showed 4 factors-sleep pattern, sleep evaluation, sleep result, and cause of sleep disturbance. These four factors explained 55.9% of total variance. Correlations between factors ranged from .15-.32. There was correlation among Korean Sleep ScaleA score, Verran and Snyder-Halpern(VSH) Sleep Scale score, and sleep satisfaction scale score, r=.71(p=.00), r=.51(p=.03), respectively, These study results partially support reliability, construct validity, and criterion related validity of Korean Sleep Scale A. Further validation study is required with other subjects and other settings.
