  • The purpose of this research was to investigate the effect of caffeine levels on calcium utilization in rats of different age and sex. Calcium utilization was compared in rats of different age(4 weeks and 10 months) and sex that were fed various levels of caffeine (0, 3.5, and 7mg/100g body weight) for 3 weeks. There was no significant difference in feed intake, serum calcium level, and ash content in tibia among the groups. Fecal calcium excretion was lower in young rats than in adults, Urinary calcium excretion significantly higher in the caffeine groups than that in the no-caffeine group. Daily retention and apparent absorbability of calcium in young rats were higher than those in adult rats. However, there was no significant difference among groups of different sex and caffeine levels. The results of this study suggest that caffeine consumption promotes urinary calcium excretion.

  • Purpose: This study is an integrative review to analyze articles about sex education for school age children in Korean journals. This study explored the year, methods, major variables and key findings of previous studies. Methods: Five electronic databases and eleven journals of nursing in Korean language were searched to find studies done until 2017. 75 papers published from 1995 to 2017 were selected (43 were survey studies and 32 were intervention studies). Results: Among the intervention studies, there was no Randomized Controlled Trial (RCT) study. Most intervention studies were conducted to change sexual knowledge and sexual attitudes. Among the survey studies, Q methodology and content analysis were used. The subjects' sexual knowledge and sexual consciousness were measured low in some studies. The sex education for school age children was composed of elementary school students' perception, understanding and needs related to sex. In addition, sex education was carried out to improve students' informational aspects such as sexual knowledge, prevention of sexual violence and secondary sexual character as well as emotional aspects such as sexual attitude. However, research on sexual consciousness, sexual values and sexual identity was insufficient. Conclusion: In order to develop an effective sex education program for school age children, it is necessary to consider the degree of their perception, understanding and needs and reflect both the social and cultural aspects as well as the informational and emotional aspects.

  • Transcranial Doppler ultrasonography (TCD) allows measurement of blood flow velocity to be made from the basal intracerebral vessels. Blood flow velocity in TCD is highly affected not only by blood vessel diameter, blood flow volume, blood viscosity, but also age and sex. Therefore, the study is focused on the correlation between TCD measurement index and sex/age. Subjects were 214 (male 147, famale 67) who had TCD for headache and stroke evaluations at Dongguk University Ilsan Hospital neurology department from December 2009 to April 2010. Sex did not show significant differences with mean flow velocity (MFV), peak systolic flow velocity (PSFV), end diastolic flow velocity (EDFV), pulsatility index (PI) and resistance index (RI) in middle cerebral artery (MCA). Although age also did not show significant differences with MFV and PSFV, EDFV has statistically decreased with age, and PI and RI has statistically increased with age. In addition, age showed significant correlation with MFV, EDFV, PI and RI, but not with PSFV. Therefore, TCD is definitely correlated with age and sex, so that those influencial factors must be considered when being tested.

  • The objective of this study was to examine how clothing pattern preferences vary accod-ing to sex role identity gender and age. Questionnaire of shirt pattern prefere-nces and short form Bem Sex Role Inventory was administered to 627 men and women(10's to 40's) in Kwangju City. Sex role identity was classified in androgynous masculine feminine and undifferentiated type. 1. The men liked thick horizon thin check and plaid pattern better than the women while the women small flower one. 2. The 10's liked thick horizon thin check and plaid pattern better than the women while the women small flower one. 2, The 10's liked thick horizon pattern better than the others, 3. On the interaction effect according to gender and age the women in their 30's liked polka dots pattern better than the men while the women in their 10's and 20's liked plaid pattern better than the women in their 30's and 40's 4. On the interaction effect according to sex role identity and age the masculine type in their 30's and 40's disliked small flower pat-tern while the feminine type in their 30's and 40's liked it. The women in their 30's liked small flower pattern while the 10's disliked it more than the others. 5. The androgynous type liked thin check and plaid pattern better than the others. The present findings provide that sex role identity gender and age influenced clothing pattern preferences. Gender and age had sig-nificant interaction effects on the preferences. The traditional connections between sex role identity and flower pattern perferences were confirmed only in the 30's and 40's.

  • This paper investigated the phonological processes of monophthongs and diphthongs in the pronounced words present in the Buckeye Corpus and compared the frequency distribution of these processes by sex and age groups to provide a clearer understanding of spoken English to linguists and phoneticians. Both orthographic and pronounced words were extracted from the transcribed label scripts of the Buckeye Corpus using R. Next, the phonological processes of monophthongs and diphthongs in the orthographic and pronounced labels were tabulated using R scripts, and a frequency distribution by vowel process types, as well as sex and age groups, was created. The results revealed that 95% of the orthographic words contained the same number of syllables, whereas 5% had different numbers of vowels, thereby proving that speakers tend to preserve vowels in spontaneous speech. In addition, deletion processes were preferred in natural speech. Most vowel deletions occurred with an unstressed syllable. Chi-square tests were performed to calculate dependence in the distribution of phonological process types for male and female groups and young and old groups. The results showed a very strong correlation. This finding indicates that vowel processes occurred in approximately the same pattern in natural and spontaneous speech data regardless of sex and age, as well as whether or not the vowel processes were identical. Based on these results, the author concludes that an analysis of phonological processes in spontaneous speech corpora can greatly enhance practical understanding of spoken English.

  • This study examined the association between marital status and mental health(depression, and suicidal ideation) of Korean adults by age and sex, using 2005 Korean National Health and Nutrition Examination Survey data. Differences of marital status in depression and suicidal ideation were assessed by age and sex-specific prevalence according to each stage of the life course. Our results indicated that adults who divorced, separated, and widowed had significantly higher risk of poor mental health than married adults. Men with no spouse at the stage of middle and older aged are reported higher in depressive symptom than married men. For the suicidal ideation, men with no spouse had higher risk of suicidal ideation through all stage of life course. Women were more likely to report depressive symptom and suicidal ideation than men through all stage of life course. But we could not found the mental health advantage of marriage among Korean women through all stage of life course. Based on findings, the study clearly indicate that the implication of marriage on mental health could be different for adults of different age group and sex.

  • Objectives: It has been demonstrated that acupuncture treats diseases while that the widespread use of that clinically and experimentally. It also has shown that electro-acupuncture(EA) is more effective than manual-acupuncture (MA). The purpose of this study was to investigate effect of EA and MA at combined acupoints on sex and age in rats. Methods: This study measured the effects of acupuncture treatment on small intestinal motility in rats. MA and EA(intensity, 5 times muscle twitch threshold) was applied for 30 minutes to the combined left and right sides acupoints on ST36, ST37, ST39 under enflurane anesthesia. EA and MA applied to the ST36, ST37, ST39 acupoints produced an elevation of small intestinal motility. Results: In experimental groups of combined left and right sides acupoints, only specified groups show elevation of small intestinal motility in male rats, 5 weeks age. Furthermore, combined left and right sides acupoints in EA and MA show differences effects according to the sex, male and female, and the age as 5, 6, 7, 8 weeks. Conclusion : Although these different according to the sex and age in rats do not have a established tendency, the present study suggest that effect of EA and MA are experimentally dependent upon the sex and age on small intestinal motility in rats.
