Water is an indispensable material for life and health, an essential ingredient for maintaining blood volume, and plays an important role in nutrient supply and waste excretion in the body. Water is also involved in hormone secretion, and when the body dehydration, the main organs cannot function and secrete stress hormones. Therefore, we investigated the changes in salivary cortisol hormone after water intake in 32 healthy adults. They were divided into two groups: The control group (N=16), which consumed water ad libitum, and the experimental group (N=16), which consumed 2L of water per day. Of blood biochemical parameters, a significant decrease in the concentration salivary cortisol hormone decreased in the experimental group. (p < 0.05). In conclusion, a steady and sufficient water intake may contribute to alleviate stress by decreasing cortisol hormone. As a result, constant intake of water appears to reduce the secretion of stress hormones by leading organs functioning properly, further improving immune function.

The main purpose of this research is to investigate the effect of Korean adults' perception of parent-child relation on their self-efficacy, child rearing practices, elderly parent care practices, and happiness. In this study the parent-child relation is a relationship between the adults' parents and the adults. The participants in the study were adults (2,632; male=1,275, female=1,357) with children in primary, secondary, and/or university, with an average age of 45.44-years-old (male=46.96-years-old, female=44.10-years-old). The results showed a direct influence of the adults' perception of parent-child relation on their self-efficacy and their child rearing practices, and an indirect influence on their happiness. This indicates that a more positive adult's perception of parent-child relation leads to higher self-efficacy and greater devotion to their child rearing practices. And furthermore, an elevated self-efficacy enhanced their happiness. Gender differences were found for the influence of adults' perception of parent-child relation on elderly parent care practices. For Korean male adults, a more positive perception of parent-child relation lead to a more active participation in elderly parent care practices. However, for Korean female adults no direct influence was found. Based on these results, a discussion of the influence of adults' perception of parent-child relation on the adults' psychological characteristics and family-members relationships is provided.

The aim of this study was to develop a standard toothbrush to determine the changes the dental arch form. Toothbrushes were collected from university students Items, such as the toothbrush head size, shape of head, numbers of tuft, neck size, neck angle, and handle size, were measured. the full mouth study models from the participants were In conclusion, the size of the head of the toothbrush for adults needs to be less than the 25mm and less than 11mm in the longitudinal and transverse directions, respectively. The choice of toothbrush is important for controlling oral hygiene and professional education on the selection of the appropriate toothbrush is needed.

The purpose of this study was to determine the effect of climbing exercise program on the spinal alignment and balance ability of students in 20's. The subjects of this study were 30 university students. Experimental group was performed climbing program combined with upper and lower extremity pattern for three times per week, during six weeks. A Self-efficacy questionnaire was used assess the self-confidence, individdual confidence, or belifes in specific tasks. The results of comparison of variations in each group showed that there was a significant difference in the training group(p<0.05). Climbing exercise program combined with upper and lower extremity pattern is effective for improvement of the self-efficay. So, these study results will be useful as reference date for improvement of the self-efficay.

This study examined the associations of smoking, alcohol drinking habits and both with the carotid intima-media thickness (CIMT) in university students. This study was performed using a CAGE (test for alcohol: cutting down, annoyance by criticism, guilty feeling, and eye-openers) questionnaire, FTND (the Fagerstrom test for nicotine dependence) questionnaire, and CIMT of university students. No statistically significant differences were observed among the CIMT results according to each CAGE level classified into 3 groups. The results of CIMT according to the FTND smoking categorization showed that the smoking group was higher than nonsmoking group (P<0.01). A statistically significant difference was observed between the left and right CIMT regarding smoking and drinking (P<0.01). In the only drink risk group, the left CIMT (19.84 rank) showed a low-ranking. The CIMT on the left (42.38 rank) and right (42.81 rank) showed high scores in the group with only the risk of smoking (P<0.01). These results suggested that there are distinct differences in CIMT and relevant risk factors between smokers and drinkers, particularly among those with a high smoking status. This study had several limitations: the study population was small; the relatively young age of the study subjects; and limited of focus on smoking, drinking and CIMT. In conclusion, cigarette smoking significantly exacerbates the adverse effects and higher CIMT on the subclinical atherosclerosis risk in young adults, which underscores the importance of prevention and cessation of cigarette smoking in young adults.

Purpose: The purpose of this study is to identify health beliefs and knowledge related to hepatitis A vaccination (HAV). Preventative behaviors related to HAV were also examined. Methods: The convenience sample of 332 students were drawn from a university in Chung-nam province. The results were analyzed using descriptive statistics, t-test, ANOVA, Scheff$\acute{e}$ test, Pearson's correlation coefficient, and stepwise multiple regression with SPSS for Windows 21.0 software. Results: Vaccination rates for hepatitis A were 23.4%. The mean scores of health beliefs, knowledge and preventative behaviors related to hepatitis A were $2.38{\pm}0.25$, $0.34{\pm}0.30$, and $3.15{\pm}0.40$ respectively. The factors found to be related to hepatitis A preventative behaviors were HAV, having the HAV antibody and health beliefs. Conclusion: An experience of HAV, having HAV antibody, and positive health beliefs related to hepatitis A may be necessary to increase voluntary hepatitis A preventive behaviors among university students. It is essential to develop the strategy of educating university students about HAV and having HAV antibody as well as reinforcing health beliefs about hepatitis A which prevent the hepatitis A occurrence.

Purpose: This correlational study was undertaken to examine the relationship among daily life stress, self-efficacy, hardiness, and health behavior of university students. Methods: Two hundred sixty five university students were gathered from the undergraduate classes. Data were collected through self-reported question- naires which included daily life stress scale, self-efficacy scales, hardiness scales, and health behavior scales. Results: The daily life stress level had a maximum score of 4 with a mean score of 2.09 and the mean score of health behavior was 2.56. A negative correlation exists among daily life stress, self-efficacy, and health behavior. The self-efficacy is positively correlated with the health behavior. According to the hardiness factor, health behavior is positively correlated with hardiness. In the subareas, health behavior is positively correlated with control, commitment, and challenge. The self- efficacy factor was positively correlated with challenge. Conclusions: In conclusion, based onthe results of this study, both self-efficacy and hardiness are useful concepts in reducing the stress level and in increasing the health promoting behavior. Therefore, it is necessary to develop a program based on both self-efficacy and hardiness.
