The $(Sr_{0.9}Ca_{0.1})TiO_3$(SCT) thin films are deposited on Pt-coated electrode$(Pt/TiN/SiO_2/Si)$ using RF sputtering method at various substrate temperature. The optimum conditions of RF power and $Ar/O_2$ ratio were 140[W] and 80/20, respectively. Deposition rate of SCT thin films was about $18.75[{\AA}/min]$. The crystallinity of SCT thin films were increased with increase of substrate temperature in the temperature range of $100\sim500[^{\circ}C]$. The dielectric constant of SCT thin films were increased with the increase of substrate temperature, and changed almost linearly in temperature ranges of $-80\sim+190[^{\circ}C]$. The current-voltage characteristics of SCT thin films showed the increasing leakage current as the substrate temperature increases.

Objectives: We investigated the clustering of selected lifestyle factors (cigarette smoking, heavy alcohol consumption, lack of physical exercise) and identified the population characteristics associated with increasing lifestyle risks. Methods: Data on lifestyle risk factors, sociodemographic characteristics, and history of chronic diseases were obtained from 7,694 individuals ${\geq}20$ years of age who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). Clustering of lifestyle risks involved the observed prevalence of multiple risks and those expected from marginal exposure prevalence of the three selected risk factors. Prevalence odds ratio was adopted as a measurement of clustering. Multiple correspondence analysis, Kendall tau correlation, Man-Whitney analysis, and ordinal logistic regression analysis were conducted to identify variables increasing lifestyle risks. Results: In both men and women, increased lifestyle risks were associated with clustering of: (1) cigarette smoking and excessive alcohol consumption, and (2) smoking, excessive alcohol consumption, and lack of physical exercise. Patterns of clustering for physical exercise were different from those for cigarette smoking and alcohol consumption. The increased unhealthy clustering was found among men 20-64 years of age with mild or moderate stress, and among women 35-49 years of age who were never-married, with mild stress, and increased body mass index (>$30\;kg/m^2$). Conclusions: Addressing a lack of physical exercise considering individual characteristics including gender, age, employment activity, and stress levels should be a focus of health promotion efforts.

High quality seed of proso millet that has high germination percentage, germination speed, and uniformity demanded to increases rates of mechanization in cereal crop cultivation. In order to improve germination characteristics, proso millet seeds were treated with red light, ultrasonication and liquid smoke (LS) solution that generated from hickory wood. All treatments were performed in seed priming solution with 100mM $NH_4NO_3$ at $15^{\circ}C$ for 24hrs under aeration condition. Seeds were exposed under light intensity of 2000 lux for 15m, 30m, 60m, and 120m in priming solution. Ultrasonic treatment was performed at 60%, 80%, and 100% intensity of 21.6 KHz for 5m, 10m, and 20m in priming solution. For LS treatment seed were soaked in 0%, 0.5%, 1.0%, 5.0% and 10.0% of diluted solution with $dH_2O$ or 100mM $NH_4NO_3$ solution. The effect of seed treatment was evaluated with germination percentage (GP), mean germination time (MGT), germination index (GI), germination rate (GR), Germination uniformity (GU) and heath seed percentage (HS). Our results demonstrate that red light (15min) or ultrasonication (21.6kHz, 5min) treatment improved MGT, GI, GR, and GU comparing to untreated control. Importantly, we show that LS treatments have significant effect on the health seedling and germination characteristics. Proso millet seeds that treated with 5% LS solution for 24hrs improves HS up to 97% that similar results obtained in 100mM $NH_4NO_3$ priming for 24hrs. The combined treatment with LS solution and 100mM $NH_4NO_3$ priming were not effective in all treatments. Our results demonstrate that treating seeds with LS or 100mM $NH_4NO_3$ priming or ultrasonication improves germination characteristics. The methods described here will help advance research using this species by increasing the germination performance at which successive seed pellet process.

This study analyzed in depth the students' health fitness trend characteristics based on the per generation characteristics longitudinal grade level document that was produced by collecting heath fitness measurements of students from all over the country for the purpose of exploring the appropriate wellness management plan. The following conclusion was derived through the collected materials and results according to the research purpose and method. First, it was determined that muscular endurance trends for both boys and girls in their elementary school period were similar for the current generation and the previous one, but as they went through their middle school period their muscular endurance development levels were found to be reduced compared with the previous generation students. Second, there was no difference in the cardiorespiratory endurance trends between the current and the previous generation students, unlike all other physical factors. Third, the boys displayed deteriorated reflex development during their growth period compared with their previous generation counterparts. On the other hand, girls displayed mostly stagnant development once they reached 8th grade level within their generation.

In this study, "housewives" are defined as married women who take care of housework mostly and do not work outside of home. Changing family types and higher education level of housewives enable them to be more interested in heath, beauty, and appearance. Increased interest and more frequent visits to hair salons cause scalp damage as well as hair damage, which results in hair loss. Moreover, some women suffers from scalp and hair damage due to childbirth, but many of them are not aware of it. Therefore, this study tries to find out the following; housewives' perceptions on hair and scalp management, and how such perceptions are formed. In addition, this study will present the direction for beauty marketing taking into account the characteristics of housewives and provide data necessary for them to keep their hair and scalp healthy. For these purposes, a survey was carried out after modifying the questionnaire through a presurvey. The survey tried to find 1) perceptions on hair and scalp management according to demographic characteristics, and attitude toward hair and scalp management according to demographic characteristics. Data were analyzed using frequency analysis, cross tabulation, t-test, factor analysis, and Analysis of Variance. The results were as follows, most recognize the importance of hair and scalp management but do not receive management because of the high cost, most of them receive information about hair and scalp management from people around them, and the higher the education level and health status, the more active the attitude toward hair and scalp management. These differences were all statistically significant.

The purpose of this research is to understand the physiological characteristics of muscular men between the ages of 20 and 34 years who are distinct from the general population due to their muscular development, and to categorize them according to upper body somatotypes. This research was conducted in order to provide basic data necessary for developing clothing products for muscular men. The research method and results were as follows: the "Sheldon's" and "Heath-Carter" somatotype classification methods were carried out at sports centers, the Athletic College, and military bases in Seoul and Gyeonggi province. Excluding the 32 subjects that did not have a balanced mesomorph, ectomorphic mesomorph or mesomorph-ectomorph, research on the remaining 168 subjects was used in the data analysis. 2. We used the following factor analysis: factor 1 for torso size; factor 2 for upper-arm, armpit, and chest breath size; and 3. The upper body was categorized into four (4) types, and their individual characteristics were as follows: Type 1 had the most developed arms, shoulders, chest muscles, and the shortest height. These subjects had an average of 191 somatotype points and could be classified as a balanced mesomorph. The heights and the lengths of Type 2 were short. They had slim physical structures, averaged 182 somatype points, and could be classified as an ectomorphic mesomorph. somatotype points and were classified as a balanced mesomorph. The heights and the lengths of Type 4 were long. They had slim physical structures, averaged 164 somatotype points, and were classified as a balanced mesomorph-ectomorph. 4. After carrying out a discriminant analysis to validate the categories of muscular men's upper bodies, we concluded that our model had an accuracy rating of 98.1%.
