The present study was aimed to investigated whether there are age-and sex-related differences in serum levels of lipid peroxides, retinol , and $\alpha$-tocopherol in Korean adults. The subjects were 441 persons , including 268 men and 173 women. Those of each sex were divided into four age group : 20-29, 30-39, 40-49 and 50-65 years, and their lifestyles and serum levels were compared . Men smoked and drank less as age increased , but 99.9% of women of did not smoke and only 11% drank more than once a month. Lipid peroxides of males increased gradually with age, while those of females showed greater levels in the 50-65 years group thon younger groups. Lipid peroxides, retinol and $\alpha$-tocopherol concentrations, which were adjusted for age, were significantly higher in males than in females. Lipid peroxide levels adjusted for total lipid were positively correlated with age in males than in females. Serum levels of $\alpha$-tocopherol adjusted for total lipid were positively correlated with age both in males and in females , while retinol was neither. The results indicate that serum levels of lipid peroxides, retinol , and $\alpha$-tocopherol are affected by age and that the response could be different between males and females.

The Influence of age on the endothelial modulation of angiotensin II (AII)-induced contractile response was investigated in isolated aortic rings of rats ranging in age from 0.7 to 20 months. Hemoglobin and L-NAME were used to examine whether age-related changes in the EDRF-releasing system were involved in endothelial modulation of All-induced contraction in rat aorta. In all five age groups (0.7, 1.5, 3, 6, 20 months), hemoglobin (10 ${\mu}$M) significantly enhanced All-induced contractile response only in aorta with endothelium intact. L-NAME (10 ${\mu}$M) Produced a significant enhancement in All responses in endothelium-intact aortas from rats aged 0.7 and 1.5 months, but it had no effect in aortas from older rats aged 6 and 20 months. Indomethacin (10 ${\mu}$M) did not affect All-induced contractile responses in both endothelium intact and removed aortas from rats at the age of 0.7 to 20 months. Hemoglobin (10 ${\mu}$M) abolished acetylcholine-induced relaxation response in aortas from young and old rats. L-NAME completely abolished the relaxation in aortas from young (0.7 and 1.5 months), but incompletely in aortas from older (6 and 20 months) rats. The sensitivity of endothelium-dependent relaxation to A23187 increased with age between ages of 0.7 and 6 months, with no further increase noted up to 20 months of age. These results suggest that endothelial modulation of AII-induced contraction in rat aorta might involve age-related alteration in EDRF-releasing system, probably via post-receptor mechanism.

In order to promote well-being during old age, it is important to start preparing early on for the later life. Based on this thesis, this study examined attitudes of the middle-aged women residing in rural towns on their preparation for old age as well as related variables. For this purpose, survey data from 200 individuals were analyzed using a SAS program. The overall degree of preparation for old age was quantified as about 67 points out of a 100 possible points. The variables that affected the level of preparedness include attitude toward using a paid nursing home ($\beta$=.23), type of agricultural work they engage in ($\beta$=-.21), who do you think is a supporter during your old age($\beta$=.20)］, type of decision-making in the household ($\beta$=.17). The explanatory power of such variables as standards of living ($\beta$=.18), family type ($\beta$=-.18), recognition of the entrance of old age ($\beta$=.17), and preparation behavior for old age ($\beta$=.15) were partially proved in three sub-areas (economical, emotional, and leisure areas) of preparation. The groundwork of this study could be used as basic materials to develop an educational program to improve the attitudes toward preparation for old age.

Purpose: Obesity affects dysfunction of Hypothalamus-Pituitary-Ovary(H-P-O) axis. Dysfunction of H-P-O axis could be related to Skin Resistance Variability (SRV). This study investigated the impacts of obesity which related to female age on SRV. Methods: We randomly selected 400 women who had taken CP-6000A test and InBody test on the same day at Oriental Hospital of Sangji University from Jan. 2008 to Jun. 2011. In this study, the Body Mass Index(BMI) range of normal group is 18.5~24.9, obesity group is over 25, the age range of childbearing age group is 24~34 years, post-menopause group is 50~65 years. 139 women that met the criteria of this study were assorted by their BMI and age. After detection of SRV, SPSS 19.0 has conjugated for data analysis and the independent samples t-test and paired samples t-test were used to verify the results. Results: At 1st and 2nd trial, the height of 3 area of childbearing age obesity group was significantly higher than that of childbearing age normal group. At 1st and 2nd trial, the height of 1, 2 area of childbearing age obesity group was higher than that of childbearing age normal group, but there were no significant difference. At 1st and 2nd trial, the height of 1, 2, 3 area of post-menopause obesity group was mostly higher than that of post-menopause normal group, but there were no significant difference. Conclusions: This study showed the SRV of obesity group was higher than that of normal group in most of 1, 2, 3 area. Further study will be needed.

Objectives: This study was performed to investigate the level of quality of life (QOL) and to identify its related factors among the elderly using a hall for the aged. Methods: The study subjects were 350 elderly people living in Nam Gu, Gwangju City. They were interviewed by questionnaire to collect information on social-demographic characteristics, health behaviors, health-related characteristics and QOL. We used statistical analysis methods such as T-test, ANOVA and multiple regression analysis to find which factors affected QOL. Results: The characteristics relating to physical functions were as follows: presence of spouse, education, alcohol drinking, teeth condition, arthritis, frequency of visiting the hall for the aged, and depression. Age, arthritis and depression were significantly related to role limitation due to physical problems. General health was related to gender, age, and depression, and vitality was related to education, frequency of visiting the hall, and depression. Role limitation due to emotional problems was related to age and depression, and mental health was related to age, hypertension, arthritis and depression. Conclusions: This study showed QOL of the elderly was significantly influenced by socio-demographic factors, and physical or emotional conditions. To improve QOL of the elderly, we need to develop programs to promote health and to manage chronic diseases of the elderly.

Influence of aging on plasma renin activity was evaluated in healthy normotensive subjects (age range $21\sim63$ years, 413 males) devoid of cardiorenal or endocrinological problems. The age-related decrease of plasma renin activity in the subjects between $21\sim28$ years group and $36\sim42$ years group was slight, but over the 43 years groups was significantly different. The age-related suppression of plasma renin activity was much more smooth and continuous all over the age ranges evaluated. The sexual difference in plasma renin activity was noticed between the subjects of 22 years old group(34 males) and 19 years grop(34 females) (p<0.003). The data suggest that the age-related suppression of plasma renin activity appeared in healthy normotensive subjects should be considered in the case of evaluation of low renin essential hypertension.

The purpose of this research was to identify the importance of emotional development in early childhood, in children ages three to five, by examining the relationship between the variables in the children such as gender, age, and temperament, as well as their mothers' emotionality, in relation to emotional development. The participants included a total of 72 children between three and five years of age. The major findings are as follow: First, there were significant differences in emotional expression and emotional recognition between the boys and the girls. Additionally, the emotional recognition of the children increased as age increased, and more positive strategies for emotional regulation were used with the increasing age of the children. Temperament characteristics did not have any relationship with emotional expression or emotional recognition, while the strategies for emotional regulation were related to the temperament characteristics. Second, the emotional expressivity of the mother was related to the emotional expression and recognition of the child, but wes not associated with strategies for emotional regulation. The emotional reactivity of the mother was related to a child's strategies for emotional regulation, but not to emotional expression or recognition. Third, emotional development of the children wes influenced by the individual child variables and emotionality of the mother.

This study was carried out to examine the correlationship among incidence, frequency, loudness, and the related predisposing factors about snoring through epidemiologic investigations. Questionaires were used for a clinic-visitor who is irrelevant to snoring, and investigated by sex, age, body mass index(below BMI), and occupation. The subjects were grouped by age; below twenties, twenties, thirties, forties, fifties, sixties, and over sixties. On using BMI, the subjects were divided into two groups; overweighed and non-overweighed group. And the occupation were simplified to two groups; physical labors and mental labors. An statistical analysis was perfomed about correlation to whether to snoring or not, its frequency, loudness and the related predisposing factors. The results were obtained as follows : 1. Snorers were commanded as 5.1% of all clinic-visitors. Male was dominant to female (p<0.01). The number of snorer was increased with age(p<0.05) and overweighed group showed higher incidence than in non-overweight group(p<0.01). 2. There was no significant difference between occupation groups in incidence of snoring. 3. In case of the frequency of snoring in snoring group, there was significant increase in male, overweighed and mental labors group(p<0.01). But, there was no difference with age. 4. In case of loudness of snoring in snoring group, male, overweihged and mental labors had louder noise than in other contrary group. But there was no difference with age. 5. For the related predisposing factors to snoring, fatigue was the highest(74.4%), and alcoho and drug were followed.

Purpose: This study aimed to develop and examine the validity and reliability of a self-efficacy scale for preventive health management related to premature labor (PHMSE-PL) for women of childbearing age. Methods: Instrument development and validation were undertaken in three steps: conceptualization through a literature review and in-depth interviews, item generation and evaluation of content validity, and evaluation of construct validity and reliability. The content validity, factorial structure validity, and internal consistency reliability of the PHMSE-PL were evaluated, and cognitive interviewing was undertaken. Data were analyzed using confirmatory factor analyses, Cronbach's α, and 95% confidence intervals (CIs). Results: The content validity was assessed by experts and was strengthened through cognitive interviews with women of childbearing age. The PHMSE-PL comprised 34 items across five factors. The construct validity of the PHMSE-PL was supported. Cronbach's α for the total scale was .97 (95% CI=.96-.97). Conclusion: An evaluation of the psychometric properties of the PHMSE-PL scale found it to be a valid and reliable tool for women of childbearing age. The scale appears to be useful for women of childbearing age to self-assess their preventive health management self-efficacy related to premature labor and for health professionals to evaluate and promote women's preventive health management.
