This study investigated the determination of speech rates, words per minute (WPM) and syllables per minute (SPM), of $5{\sim}7$ year-old normal children to understand if there are any differences in the rates according to the children's age and sex. All participants were required to conduct story retelling tasks (SRT) and picture description tasks (PDT). In SRT, there was a significant difference between the groups of 5 year-old and 7 year-old children on WPM. However, there was no significant difference between the groups of ages regarding SPM. In addition, there was no significant difference between the groups according to sex on WPM and SPM. In PDT, there was no significant difference between the groups according to their ages and sex on WPM and SPM. The current research found that the speech rates of the preschool children might be somewhat different in their utterance abilities according to their age, but there was no obvious difference according to their sex. The findings can advance development of a clinical tool to screen children with fluency disorders and to determine the steps in establishing speech rates of children in the language development period.

The purpose of this study was to examine how the family of origin and self-disclosure of unmarried persons in early adulthood affected their own intimacy with the opposite sex, which was one of the major developmental tasks for them. The findings of the study are as follows: First, the self-differentiation, self-disclosure, and intimacy with the opposite sex of the single male and female adults investigated were generally at a moderate level. Second, for self-differentiation, the background variables of the male and female adults made no statistically significant difference. For self-disclosure, the background variables of the female adults made no statistically significant difference to that, but the male adults differed significantly from one another in that regard according to their family makeup and birth of order. As for connections between the background variables of the single male and female adults and their intimacy with the opposite sex, the male adults varied in that aspect with their birth order, and whether they were dating and considered getting married made a difference to that as well. In the event of the female adults, whether they considered getting married and how long they were dating made a difference in their intimacy with the opposite sex. Third, concerning the relative influence of the self-differentiation and self-disclosure of the unmarried male and female adults on their intimacy with the opposite sex, their intimacy with the opposite sex improved as division occurred from their original families, when they opened themselves up to more people, when they thought of marriage more and when they were dating for a longer period of time.

Soy isoflavones have been hypothesized to exert hormonal effects and to enhance bone mineral density in postmenopausal women. To test this hypothesis, we studied the effects of soy isoflavones supplements on bone mineral density and sex hormones (serum estradiol, sex hormone-binding globulin and testosterone) in 47 postmenopausal women. There were 24 participants in the treatment group and 23 in the control group. The treatment group consumed the isoftavones extract capsule daily (which contained 90 mg of soy isoflavones) for 12 weeks. The study compared pre- and post-isoflavones intake in the following areas: physical examination, diet survey, bone mineral density and serum sex hormone levels. The average age of the treatment group was 64.63 years and that of the control group was 66.48 years. There were no significant differences between the two groups in terms of height, weight, and body mass index. Both groups maintained regular diet patterns in terms of their average daily nutrient intake. There was no significant difference between the treatment group (18.49 mg) and the control group (21.27 mg) in terms of daily isoflavones intake based on diet. The 12-week analysis of bone mineral density change after taking isoflavones supplements demonstrated no significant differences in the following : lumbar spine BMD (0.82 g/$\textrm{cm}^2$ in pre versus 0.81 g/$\textrm{cm}^2$ in post), femoral neck BMD (0.58 g/$\textrm{cm}^2$ in pre versus 0.57 g/$\textrm{cm}^2$ in post) in the treatment group. There was no significant difference in serum estradiol in the isoflavones treatment group. The subjects indicated no significant difference in serum testosterone in the isoflavones treatment group. But the subjects indicated a significant difference in sex hormone-binding globulin (60.04 nmol/L in pre versus 52.39 nmol/L in post) in the isoflavones treatment group at the levels of p < 0.05. The significant decrease in sex hormone-binding globulin did indicate the need for long-term study on isoflavones supplementation as well as its positive effect on bone mineral density.

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.

The purpose of this study was to examine the sex-consciousness and sexual values of school children by geographic region. It's specifically attempted to make a comparative analysis of sex-consciousness and sexual values between urban and rural elementary schoolers to help provide efficient sex education for them to build the right sexual values. The subjects in this study were 400 elementary schoolers in their sixth year of elementary schools located in Danyang-gun and Chungju city, north Chungcheong province. After a survey was conducted, answer sheets from 387 students that were analyzable were analyzed. For data handling, SPSS program was employed, and t-test was utilized to see if there's any differences between the urban and rural elementary school youngsters in sex consciousness and sexual values. And $x^2$ test was used to make a comparative analysis of their view of sex education. The findings of the study were as follows : First, regarding sex-consciousness, they had general knowledge on sex. Especially, they were highly aware of sexual violence and the generation of baby, but many of them didn't know about where and how egg cells were produced. This indicated that systematic education should be offered in various ways. Concerning geographic gap, there was a significant difference in sexual knowledge between the urban and rural students. As to sexual attitude, they took a relatively positive attitude toward display of affection or sex-related talk on TV or in movies, as they viewed it as natural. This finding implied that the elementary schoolers were recipient toward sex and took an active attitude toward sexual expressions. Concerning geographic gap, there was no difference between the rural and urban students. As for sexual practices, the largest group of the students had a liking for the opposite sex, which showed that their needs for sex were unveiled in the course of having some trouble due to the other sex rather than through firsthand experiences or activities. As to geographic gap, there was a significant difference between the urban and rural students in that regard. Besides, the urban students put their sex-consciousness in practice more often than the rural students did. After they are educated to build the right sexual values, systematic sex-education programs should also be offered for them to be exposed to sustained sex education and to team how to apply their sex-consciousness to real life. Second, as for sexual values, the school children had relatively positive and equalitarian sexual values. Regarding geographic gap, there were significant gaps between the two groups' view of the opposite sex, sexual roles and chastity. Concerning view of the opposite sex, they attached more importance to the inner aspects of the opposite sex than his or her look, and they wanted to date in a natural manner. Regarding sexual roles, they were relatively well cognizant of gender equity and the importance of male and female roles. As to view of chastity, they looked upon sex as natural, not as what's ugly or ashamed of. Third, concerning their outlook on sex education, approximately more than half the students felt the needs for sex education, and there was a significant difference between the urban and rural students. They wanted to receive education about the prevention of sexual violence and physical changes during puberty the most, and there was a significant gap between the urban and rural students in this aspect. As to the time for sex education, they thought that students should start to be exposed to sex education in their fifth or sixth year. This finding signified that fifth or sixth graders who were in the beginning of puberty started to have a lot of interest in their own physical changes. Therefore, sex education would produce better effects when it's provided to fifth or sixth graders. Nearly half them preferred single-gender class when they received sex education, and there's no gap between the urban and rural students in that regard.
