Background and Objectives : The nasalance score measured by Nasometer is a supplementary data for the perceptually rated nasality by a trained speech pathologist. The nasalance score varies with subjects. The objective of the present study was to examine whether there are differences in nasalance scores as a function of age and sex. Materials and Method : This study used 20 normal chidren aged from 3 to 8 and 40 normal adults aged from 21 to 37(male : female= 1 : 1) as subjects. The nasalance scores were analyzed in 3 different phonetic contests(nasal, /i/ vowel,/a/ vowel) and 4 different sentence lengths(1, 2, 4, 8 syllable). Results : The children had significantly higher nasalance scores in short sentences an the adults. The female subjects had significantly higher nasalance scores in nasal sentences and in short sentences than the male subjects. Conclusion : These results may indicate that sex and age differences should be considered in the interpretation of the nasalance score in nasal sentences or in short sentences.

This study investigated social determinants and their interaction effects on the health of school-aged children in diverse environmental factors pertaining to the individual, family, and peers from an ecological systematic perspective. Data were drawn from the first wave of the Korean Children and Youth Panel Survey (KCYPS) developed by the National Youth Policy Institute and conducted in 2010. Data were analyzed by descriptive statistics, Cronbach ${\alpha}$, correlation, and hierarchical regression analysis using SPSS ver. 18. The results from this study showed that sex and age were related to the health of school-aged children, as social determinants. Self-rated levels of the health of boys and younger children were more positive than girls and older children; in addition, levels of self-resilience, satisfaction of peer relation, and parenting rearing attitude were found to have a positive impact on self-rated levels of the health of school-aged children as protective factors. Especially, according to the result of interaction analysis between factors, self-resilience, and parenting rearing attitude were moderators of the effects on between sex and household income and self-rated level of the health of school-aged children respectively. The findings from this study suggested the need to expand the social intervention range to improve school-aged children's health.

The MRI (magnetic resonance imaging) volumetric analysis of the brain was performed in 59 healthy elderly Koreans (aged 62-76 years; 34 male, 25 female) to investigate whether the previously reported significant correlations between body height and brain volumes in the young aged Koreans (20's) still exist in the old aged Koreans (60's and 70's). Unlike previously reported significant correlations in the young aged Koreans, neither the correlation between whole brain volume and body height in male nor the correlation between cerebellar volume and body height in female show any significance in the old aged Koreans. The significant correlation between body height and whole brain volume was still observed when both male and female data were combined (r=0.27, P<0.05), but the correlation coef-ficient and the level of significance markedly decreased from those of previously reported Korean youth data (r=0.67, P<0.01). Simple linear regression analysis shows decrease of explanatory power of height (measured in $r^2$) from 44% in the youth group to 7% in the old age group on the variance of whole brain volume. Multiple linear regression analysis shows that age and sex, rather than height, are major explanatory variables for whole brain volume in the old aged Koreans. The loss of correlations in the aged group is suspected to be mainly due to age related brain volume changes.

Objectives: The aim of this study was to identify the associations with social support, stress coping strategy and depression among some urban middle-aged men and women. Methods: Considering the regional distribution 4 districts of Seoul were conveniently selected for this study and a total of 329 middle-aged men and women participated in the self-administered survey. The survey questionaries included social support, stress coping strategy, depression and general characteristics. Results: Avoidance and problem solving strategies were significant independent variables to the men's depression scores, but social support was not significant. However middle aged female's social support more explained the variance of the depression scores than the problem solving strategy. Conclusions: Significant sociopsychological factors that affected middle-aged depression were different by sex and according to the results, stress coping strategy for men and social support for woman were significant factors on depression control in urban middle-aged population.

Several studies have shown that the stomach has sufficient alcohol dehydrogenase (ADH) activity to metabolize some amount of orally administered alcohol and the sex-related differences in the first-pass metabolism of alcohol might be associated with differences in the activity of gastric ADH(GADH). The aim of this study was to asses the sex-related differences in GADH in 48 male and 48 female Sprague-Dawley rats aged 1, 4, 10, 15, 20, and 30 weeks which each aged group had same sex ratio. The GADH activity was determined spectrophotometrically at 37$^{\circ}C$. The formation of NADH was monitored at 340nm for 10 minutes in the 1 ml of reaction mixture (0.5 M of Tris-HCl, pH 7.2 + 1.5 M of ethanol + 2.8 mM of NAD + 30 $\mu$l gastric mucosal supernatant). The GADH activity (nM of NADH/min/mg of cytosolic protein) was calculated using molecular extinction coefficient of 6.22 $\textrm{cm}^2$/$\mu$M for NADH. The GADH activities were 2.94$\pm$0.82 (n=48) in female rats and 3.34$\pm$2.17 (n=48) in male rats and had not significant difference between sex. However, the GADH activities were significantly (p<0.01) higher in female (1.91$\pm$0.59 and 3.30$\pm$0.49) than in male (0.68$\pm$0.43 and 1.92$\pm$0.81) of 1 and 4 weeks rats. However, it was significantly (p<0.05) higher in male (6.48$\pm$1.81, 3.65$\pm$1.04 and 5.13$\pm$1.30) than in female (4.23$\pm$1.23, 2.18$\pm$0.77 and 2.56$\pm$0.93) of 10, 20 and 30 weeks rats, respectively. Therefore, the results suggested that sex-related differences of the GADH activities in same aged rats were existed by age.

Background: Sampling a healthy reference population to generate reference intervals (RIs) for complete blood count (CBC) parameters is not common for pediatric and geriatric ages. We established age- and sex-specific RIs for CBC parameters across pediatric, adult, and geriatric ages using secondary data, evaluating patterns of changes in CBC parameters. Methods: The reference population comprised 804,623 health examinees (66,611 aged 3-17 years; 564,280 aged 18-59 years; 173,732 aged 60-99 years), and, we excluded 22,766 examinees after outlier testing. The CBC parameters (red blood cell [RBC], white blood cell [WBC], and platelet parameters) from 781,857 examinees were studied. We determined statistically significant partitions of age and sex, and calculated RIs according to the CLSI C28-A3 guidelines. Results: RBC parameters increased with age until adulthood and decreased with age in males, but increased before puberty and then decreased with age in females. WBC and platelet counts were the highest in early childhood and decreased with age. Sex differences in each age group were noted: WBC count was higher in males than in females during adulthood, but platelet count was higher in females than in males from puberty onwards (P <0.001). Neutrophil count was the lowest in early childhood and increased with age. Lymphocyte count decreased with age after peaking in early childhood. Eosinophil count was the highest in childhood and higher in males than in females. Monocyte count was higher in males than in females (P <0.001). Conclusions: We provide comprehensive age- and sex-specific RIs for CBC parameters, which show dynamic changes with both age and sex.

Background: Due to an increasing number of workers aged 50 years and above, the number of those employed is also on the rise, and those workers aged 50 and over has exceeded 50% of the total fatal occupational injuries. Therefore, it is necessary to implement the selection and concentration by identifying the characteristics of high-risk groups necessary for an effective prevention against and reduction of fatal occupational injuries. Methods: This study analyzed the characteristics of high-risk groups and the occupational injury fatality rate per 10,000 workers among the workers aged 50 and over through a multi-dimensional analysis by sex, employment status of workers, industry and occupation by targeting 4,079 persons who died in fatal occupational injuries from January 2007 to December 12. Results: The share of the workers aged 50 years and above is increasing every year in the total fatal occupational injuries occurrence, and the high-risk groups include 'male workers' by sex, 'daily workers' by worker's status, 'craft and related-trades workers' by occupation, and 'mining' by industry. Conclusion: The most frequent causal objects of fatal occupational injuries of the workers aged 50 years and above are found out to be 'installment and dismantlement of temporary equipment and material on work platforms including scaffold' in the construction industry and 'mobile crane, conveyor belt and fork lifts' in the manufacturing industry.

Purpose: The purpose of this study was to investigate factors determining health behavior for middle-aged adults in relation to stress coping behaviors, cognitive factors, social support, and sociodemographic variables. Method: The questionnaire survey was carried out on a convenience sample of 203 middle aged in a community settings. The data analysis procedure included frequency, t-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regressions using health behavior as dependent variable. Result: Among the sociodemographic variables, factors such as sex, educational and eonomic levels were associated with the health behaviors. There were significant correlations between health behaviors and saliency of health, social support, and positive-stress coping behaviors. Stepwise multiple regression revealed that the factors such as positive-stress coping behaviors, saliency of health, sex, and education turned out to be significant affecting factors. Twenty eight percent of varience in health behavior was explained by these factors. Conclusion: Positive-stress coping methods were turned out to be the most important effective factors in practicing of health behaviors of middle aged. The necessity of an intervention considering the situation related to their stress and coping methods in middle aged so as to promote positive health behaviors was suggested.
