The purpose of this study was to examine the feasibility of standardizing the Bayley Scales of Infant Development(BSID) for Korean infants. To examine whether the Korean version of BSID is appropriate for Korean infants during the first 30 months of age, the Scale was administered to 285 Korean infants in 14 age groups. The infants were from intact and mostly middle-class families. According to item rewponse analyses of the Mental and the Motor Scales, the passing rate on each item increased by the infant's age. Regularity rather than irregularity was found on most items. Ordinarily of the Mental and the Motor Scale items in terns of age placement was similar to that of the U. S. sample. Several items, however, could be rearranged based on the data from the Korean sample. The total scores of the Mental and the Motor Scales reflected developmental trends in which score differences with a conjoining age group ranged from 3 to 15 for the Mental Scale, and 2 to 10 for the Motor Scale. Correlations between the two Scales in each age group were low to moderate (.03 to .67), with a median of .34. Reliabilities of the Korean version of the BSID in terms of the split-half reliability coefficients and the tester-observer agreements were satisfactory. Similarities as well as differences were found in developmental trends of infants between two cultures. A further study is needed not only to confirm results of this study but to set forth the standardization of the Bayley Scales to Korean infants.

It is common practice to identify the insulation faults of GIS through monitor the contents of SF₆ decomposed components. Partial discharges (PD) could lead to the decomposition of SF₆ dielectric, so new reactions usually occur in the mixture of the newly decomposed components including traces of H₂O and O₂. The new reactions also cause the decomposed components to differ due to the different amounts of H₂O and O₂ even under the same strength of PD. Thus, the accuracy of assessing the insulation faults is definitely influenced when using the concentration and corresponding change of decomposed components. In the present research, a needle-plate electrode was employed to simulate the PD event of a metal protrusion insulation fault for two main characteristic components SO₂F₂ and SOF₂, and to carry out influence analysis of trace H₂O and O₂ on the characteristic components. The research shows that trace H₂O has the capability of catching an F atom, which inhibits low-sulfide SF_x from recombining into high-sulfide SF₆. Thus, the amount of SOF₂ strongly correlates to the amount of trace H₂O, whereas the amount of SO₂F₂ is weakly related to trace H₂O. Furthermore, the dilution effect of trace O₂ on SOF₂ obviously exceeds that of SO₂F₂.

This study was conducted to compare the dietary characteristics of middle-aged people with different obesity index or food habits. Questionnaires were collected from 480 subjects in Daejon. The data were analyzed by $X^2$-test and ANOVA. The subjects were distributed into the normal weight group(66.3%), overweight group(18.3%) and underweight(15.4%) based on BMI. Twenty-five percent of males and 23.0% of females in the 50＇s belonged to the overweight group. The least consumed food was milk or milk products among the five basic food groups. The frequency of exercise was low in their daily life. The had better food habits than the males. The overweight group had worse food habits than the normal weight or underweight group. The underweight group ate light meal and ate slowly. The better the subjects had, the more regularly they took breakfast(p＜0.001). The good food habits group were more interested in their dietary life and were more careful in selecting foods for their health than the bad food habits group(p＜0.001). Based on the results of this study, the practical education programs should be focused on more intake of milk or products and on daily exercise for the self-health maintenance of middle-aged people. Also, proper education programs should be developed for males and females in their 50＇s to practice weight control and regularity of meals in their life, and to utilize nutrition knowledge in dietary life. Further research on the comparision of dietary characteristics are needed with consideration of the subjects ratio according to BMI.

The purpose of this study was to investigate the effects of eating habits and control of overeating of obese children on the body weight control program. The program included nutritional education, psychotherapy and physical exercise on weekly session for 9 months. The results of this study were as follows. Participants of the study involved 30 obese children attending elementary school. The average age of the children was 11.78 years, mean height and weight were 146.22cm and 50.61kg. The average BMI and body fat contents were 24.06 and 30.49% respectively and WHR of the children was 0.87. There was a significant difference between boys and girls' BMI(25.18, 23.31, p<0.01). As a result of the eating habits test, 50% of the subjects showed low level of regularity of diet, and 76.7% of the subjects showed high level of balanced diet score. Large portion(83.3%) of the subjects had high level of healthy behavior score. WHR of girls significantly decreased from 0.86 to 0.82(p<0.01) after the body weight control program. There were no significant differences in serum components of the obese children after the program. When regarding the score of eating habits in relation to obesity indices, the WHR significantly decreased(p<0.05) in a group of children with high eating habits score. Also in the group of overeating controls, significantly decreased WHR(p<0.05). In the results of correlation analysis, body weight was positively correlated with BMI(r=0.624), the level of total cholesterol(r=0.5109) and HDL cholesterol(r=0.5088). The score of healthy behavior was positively correlated with height(r=0.5286) and negatively correlated with the level of LDL cholesterol(r=0.3555) and WHR(r=0.4028) These results suggest that the body weight control program must be considerate of the different groups of children with different scores in the eating habits and overeating controls test.

요즈음 아동에게 가장 큰 영향을 미치는 미디어 콘텐츠 중 하나는 '캐리와 장난감 친구들'이다. 이 콘텐츠는 아동에게 모방 놀이를 유발했다. 이 놀이에는 몇 가지의 특징이 있었다. 첫째, '캐리 놀이'를 하는 아동들은 자발적이고 적극적으로 즐거움을 추구했다. 그런데 그 즐거움을 얻기 위해서는 철저한 준비가 필요했다. 둘째, 놀이에 대한 동기 근원이 모호했다. 놀이하는 사람을 따라하는 놀이이다 보니 놀이를 즐기는 장면에서는 내적 지향이 뚜렷하게 드러나지만 놀이자를 따라하는 놀이에서는 외적 요인인 타인의 시선을 기대하는 모습을 보였다. 셋째, 이 놀이는 규칙성은 높고 자유도는 낮았다. 아동들은 전형적인 순서와 대사를 따라 놀이를 진행했다. 자유롭게 진행할 수 있는 영역은 종종 축소되었고, 확장되어도 정형화 된 형태로 마무리 되었다. 넷째, '캐리 놀이'는 견고한 놀이 세계를 구축했다. 시공간적으로 분리된 놀이 세계가 확립되었고, 참여자들은 새로운 이름을 갖게 되었다. 그러나 이 세계는 확산성이 없었다.

The purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and R$\ddot{o}$hrer Index were 12.4 years, 68.6 kg, $29.6kg/m^2$, and 194.9 in boys and 12.7 years, 65.7 kg, $29.8kg/m^2$, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.

The purpose of this study is to understand the relationship between female college students' stress level and premenstrual syndrome so that it can provide baseline data on how to cope with the syndrome. The study subjects are 250 female college students in Gyungbook area. This study chose 199 appropriate subjects and collected data. As per general menstrual phases, this study investigated the age when one had her first period, regularity and duration of period, and amount of bleeding. It used a measurement tool to measure stress level and premenstrual syndrome. Most of the subjects experienced their first period before the age of 13. The menstrual period was irregular with the duration of less than 7 days. 123 subjects had normal amount of bleeding. 121 subjects were experiencing high level of stress over 2.4. The correlation between the level of stress and premenstrual syndrome factors showed significant static correlation for each factor. Especially, the correlation between digestive system and response of autonomic nervous system was .996 and negative emotion and behavioral change was .635, and negative emotion and pain was .614 which were relatively high. The regression analysis of factors of premenstrual syndrome depending on the subjects' stress level indicated that response of autonomic nervous system had the biggest effect in the low stress group while behavioral change, negative emotion, pain, decreased concentration, water congestion, response of autonomic nervous system, and skin change had the biggest effect in the high stress group with statistical significance. Based on the result, it can be said that higher premenstrual stress is closely related to the premenstrual syndrome one experiences for some female college students.
