The purposes of this study were to identify the relationship between children's personality traits and self-esteem, and to find out if there were any differences in the relationship patterns in terms of children's sex. The questionnaire were collected from 984 subjects in 5th grade of elementary schools located in cities of Seoul, Suwon, Daejeon, and Daegu. Results showed that personality factors such as stability, sociability, responsibility, and superiority had stronger correlations with self-esteem factors whereas masculinity, activity level, and reflectivity did so to a less degree. Children's personality factors such as superiority, sociability and responsibility were better predictors of their self-esteem factors such as scholastic competence, social acceptance and general self-worth. Girls showed higher level of stability, sociability, responsibility and superiority, however there was no sex difference in the self-esteem such as scholastic competence, social acceptance and general self-worth. Children's behavioral conduct were mainly explained by masculinity, activity level, and responsibility. Responsibility turned out to be the strongest predictor of behavioral conduct among boys, while the activity level did among girls.

This research was attempted to investigate the sex bias in nutrition knowledge, food preference and food roles in the family. 152 couples living in Seoul, Cheonan in the 205∼605 were selected for this research as subjects from October 1 to December 20, 1991. The data analysis was made by way of ire quency, percentage, X2-test using SPSS package. The summarized results are as follows. 1. The survey on the sex bias in nutrition knowledge related heart disease on the subjects showed that there were no significant differences between men and women. But women had a relatively good nutrition knowledge than men. Especially women had a good nutrition knowledge that low sodium diet and exercise are efficient on preventing heart disease. 2. On the food preference, the subject showed significant difference between men and women. Men showed a relatively highest preference for protein food just as pork, fish, and tofu. Women showed a relatively highest preference for bread, fruit and vegetable. 3. On the food roles, the subjects showed that gender difference in household labor regarding food preparation still exit. Food-related activities are clearly still the domain of women in most families.

Background: The study of the medial antebrachial cutaneous nerve (MABCN) is an underused electrodiagnostic tool. But its use is often crucial for assessing mild lower brachial plexus or MABCN lesions, and sometimes for differentiating an ulnar mononeuropathy from a lower brachial plexopathy. This study was designed to know the difference of amplitude and velocity in a stimulation method (orthodromic vs antidromic), side of an arm and sex according by age. Method: MABCN conduction studies were performed orthodromically and antidromically in 90 subjects (42 women and 48 men, ranging from 22 to 79 years of age). We divided subjects into three groups by age (group 1: 20-39 years, group 2: 40-59 years, group 3: 60-79 years). The mean sensory nerve action potential amplitudes and sensory nerve conduction velocities in each group was compared by stimulation method, side of an arm and sex. Result: The amplitudes and velocities made a significant difference between orthodromic and antidromic method in all age groups. At comparison in amplitude and velocity by side of an arm, only amplitude was significantly higher in right arm than left by any stimulation method. The amplitudes and velocities were of no statistically differences in sex except amplitude checked orthodromically in right arm. Conclusion: This study suggests that there is the differences in conduction study of MABCN by stimulation method and side of an arm.
