The purpose of this study was to investigate children and their mothers'purchasing behaviors for children's clothing. A self-administered questionnaire survey was conducted to 640 students(5, 6th graders) and their mothers in the elementary schools in Seoul; 517 were used for the data analysis. Most children wanted to have clothing when they feel not having proper clothing to wear. When parents purchased a clothing, female students more actively expressed her opinion than male students. The comfort was the most important criteria by children about new clothing, and children most complained of monotonous style for their clothing after using the clothing. Mothers usually bought children clothing in changing season. The most important evaluatived criterion was design. The lower level of mothers'clothing interest had less complain than other groups about children's clothing.
This study was an investigation of obesity, food habits and daily nutrient intakes of the 4th grade elementary school students in daejeon. A total of 148 children(male:71, female:77) participated in the study. We classified the subjects into normal group and obese group according to the grade of obesity indices by body fat ratio(BFR), 70% of the male and 31% of the female were obese group. The average height, weight were $140.1{\pm}4.9cm$, $33.0{\pm}3.6kg$(obese group), $141.9{\pm}5.7cm$, $42.0{\pm}3.6kg$(normal group) for the male, $141.2{\pm}6.4cm$, $42.4{\pm}6.2kg$(obese group), $139.5{\pm}6.4cm$, $33.0{\pm}4.5kg$(normal group) for the female. Weight showed a noticeable increase in the obese group, but height was not statistically significant. In dietary habits, it wasn't statistically significant but male obese group showed statistically increase in terms of eating fast(p>0.05) and eating snacks before sleeping(p>0.01) and female obese group was higher in frequency of eating out a month than normal group. Energy intakes of obese group was more than normal group and the average intakes of Vit. A, folic acid, Ca, were below the RI. The average intakes of vit A, vit C, folic acid, Ca, were also below the RI in normal group. The average intakes of vit A, folic acid, Ca, Fe were below the RI in female. Especially in female the intake of Ca was only 53.6%(obese group), 56.4%(normal group) of RI. From these results, we knew prevalence of obesity in elementary school students were high and obese groups were high in energy intakes but low in essential nutrients. Therefore we have to try to prevent and treat childhood obesity. So nutrition education of balanced diet and good dietary habits is needed for elementary school students.
Objectives: The purpose of this study was to assess the association between pet ownership and asthma symptoms in Korean children. Methods: This study used data from the 8th Panel Study on Korean Children in 2015. For the final study, 1598 cases were used. Wheezing as an asthma symptom was self-reported as an outcome variable. Whether children had owned dogs or cats or not was used as an independent variable. Results: A total of 6.8% of children lived with dogs and 2.1% of children lived with cats in their homes. There were 4.0% of children who had asthma symptoms in the past year. When comparing 'children who had owned dogs for more than 12 months' with 'children who had not owned dogs', the adjusted odds ratio (OR) for 'asthma symptoms' were 1.20 (95% confidence interval (CI), 1.10-1.30) among male children and 2.19 (95% CI, 1.94-2.46) among female children. When comparing 'children who had owned cats for more than 12 months' with 'children who had not owned cats', the adjusted ORs for 'asthma symptoms' were 38.94 (95% CI, 35.55-42.65) among male children and 5.32 (95% CI, 4.60-6.16) among female children. When comparing 'children who had owned both dogs and cats for more than 12 months' with 'children who had not owned at all', the adjusted OR for 'asthma symptoms' was 13.22 (95% CI, 11.93-14.65), and when comparing 'children who had owned cats only' with 'children who had not owned at all', the adjusted OR for 'asthma symptoms' was 9.25 (95% CI, 8.50-10.08). Conclusions: As a result, children's asthma symptoms were higher in the case of cats than with dogs, and in the case of cats, boys were more at risk than girls. In the analysis for the risk of asthma symptoms when a dog and a cat are raised at the same time, it was statistically confirmed that the children in the home were more at risk than with single animal ownership. The results of this study can be considered to be of great importance in policy-making and for the use of educational materials in the field of environmental health.
Gender role flexibility in social and non-social situations across 4 areas of gender-role concepts(appearance, activities, occupations, and personality traits) were studied in 74 1st, 3rd, and 5th grade children. They were interviewed with 16 pictures depicting cross-gender characteristics. Children showed higher flexibility in social than in non-social situations. In social situations, children justified cross-gender characteristics in all 4 areas of gender-role concept. In non-social situations, children showed (a) highest flexibility in occupations and lowest in appearance, (b) lower flexibility toward male than female target children, (c) peak flexibility at age 8, then remaining the same except for appearance, and (d) higher flexibility in girls than in boys. In social and non-social situations children gave variable justifications for flexibility.

In the knowledge-based society, a nation's national power depends on IT industry. Also, literacy and application of IT technology can make a person live in comfortable circumstances. Currently, a few outstanding people lead entire IT industry and academy. In this sense, it is necessary to identify and nurture the gifted children in IT as early as we can. The purpose of this paper is to investigate gender difference of the gifted students in IT. Especially we are interested in their grade difference so that we select programming ability and logical thinking ability as academic performance evaluation. For this purpose, the gifted children in gifted science education center attached to a university at Seoul Metropolitan Area are selected. Their grades for 8 years were collected and analyzed. The analysis results show that there is no significant difference between male students and female students for programming ability and logical thinking ability. This also means that there is no academic difference between male and female students for the gifted children in IT.
The objective of this study was to investigate the sibling relationship, the attachment to parent and peer according to children's gender, birth order, and sibling gender composition. For this purpose, 697 male and female elementary students answered the questionnaire, who were selected because they had only one sibling. The date were analysed by t-test and partial correlation. The major finding of this study showed that children who had same sex of sibling perceived more positive way to their younger sibling then children who had different sex of sibling and that children who had female sibling perceived more positive way to sibling relationship, attachment to parent and their peers than children who had male sibling.
This study investigated the relationships between parental child-rearing practices in early childhood and the perceived self-efficacy of college students. Subjects were 322 students attending 4-year universities. The sample was 66.1% female and had a mean age of 19.9 years. Research was conducted using questionnaires and descriptive analysis, correlation analysis, t-tests were used for data description and analysis. The major findings were as follows: 1) The difference between boys and girls in terms of parental child-rearing practices perceived by children was found. Girls perceived their parents’child-rearing practices as being more positive in early childhood than those of boys. 2) The difference between male and female students in terms of the level of the self efficacy was not found. 3) The difference between paternal and maternal child-rearing practices perceived by children was found. Children perceived maternal child-rearing practices as being more positive in early childhood than paternal child-rearing practices. 4) Parental child-rearing practices in early childhood was rebated to the self-efficacy of college students. Children who perceived their parents’child-rearing practices as being more positive in early childhood had a higher level of self-efficacy. The results support the importance of parental child-rearing practices in early childhood on the developmental pathways of children.
We have investigated the relationship between food allergen sensitization and allergic disease in 74 child (male 47, female 27) patients from 0 to 14 years of age diagnosed with allergic disease. The age distribution for the study was: newborn to 3 years old, 34 children; 4 to 6 years old, 24 children; 7 to 9 years old, 8 children and above 10 years old, 8 children. Of the 74 children, 10 children were allergic to 3 of the 21 types of foods tested, 21 children were allergic to 4 types and 15 children were allergic to 5 types. The results of specific IgE tests for class 2 (0.070-3.49 IV/mL, IgE density in serum) showed that 29 children were allergic to milk, 28 children to bean, 21 children to cheese, 7 children to egg, and 18 children to pork, while over class 2, 20 children were allergic to bean, 17 children to milk, 24 children to cheese, 20 children to egg, and 21 children to pork. A questionnaire was used to survey family allergy history and diet patterns for 40 child (male 22, female 18) patients with allergic disease. The frequencies of a family history of allergy were 45.5% for males and 50.0% for females. The allergic diseases included atopic dermatitis: 26.0%, atopic nasitis: 10.5%, atopic dermatitis + atopic nasitis : 31.5%, hives: 21.0%, and asthma: 10.5%. Children on diets of mixed breast feeding and infant formula were more allergic than those on either breast feeding or infant formula feeding. Eliminated allergenic foods were egg + milk: 12.5%, egg: 10.0%, and milk 2.5%.
This study examined if support from separated children as a factor of depression was distinguishable between male and female elderly individuals living in one-person households. This study analyzed data of 2,354 elderly individuals living in one-person households(407 males and 1,947 females) who were 65 years of age or older using data from the 2014 National Elderly Survey on Living Conditions and Need for Welfare. Employing logistic regression, IADL, self-rated health, and, friends were important for male elderly individuals living in one-person households, while self-rated health, friends, employment, chronic diseases, and emotional support from separated children were noticeable for female elderly individuals living in one-person households. To better understand the mental health needs by gender of elderly individuals living in one-person households, their differences in emotional support from separated children, should be considered.
The maximum breathing capacity (MBC) and the maximum mid-expiratory flow rate (MMF) are widely used in evaluation of the ventilatory function, among various parameters of pulmonary function. The MBC volume is the amount of gas which can be exchanged per unit time during maximal voluntary hyperventilation. Performance of this test, unlike that of single breath maneuvers, is affected by the integrity of the respiratory bellows as a whole including such factors are respiratory muscle blood supply, fatigue, and progressive trapping of air. Because of this, the MBC and its relation to ventilatory requirement correlates more closely with subjective dyspnea than does any other test. The MMF is the average flow rate during expiration of the middle 50% of the vital capacity. The MMF is a measurement of a fast vital capacity related to the time required for the maneuver and the MMF relates much better to other dynamic tests of ventilatory function and to dyspnea than total vital capacity, because the MMF reflects the effective volume, or gas per unit of time. Therefore, it is important to have a prediction formula with one can compute the normal value for the subject and the compare with the measured value. However, the formulas for prediction of both MBC and MMF of the Korean children and adolescents are not yet available in the present. Hence, present investigation was attempt to derive the formulas for prediction of both MBC and MMF of the Korean children and adolescents. MBC and MMF were measured in 1,037 healthy Korean children and adolescents (1,035 male and 1,002 female) whose ages ranged from 8 to 18 years. A spirometer (9L, Collins) was used for the measurement of MBC and MMF. Both MBC and MMF were measured 3times in a standing position and the highest values were used. For measurement, the $CO_2$ absorber and sadd valve were removed from the spirometer in order to reduce the resistance in the breathing circuit and the subject was asked to breathe as fast and deeply as possible for 12 seconds in MBC and to exhale completely as fast as possible after maximum inspiration for MMF. During the measurement, investigator stood by the subject to give a constant encouragement. All the measured values were subsequently converted to values at BTPS. The formulas for MBC and MMF were derived by a manner similar to those for Baldwin et al (1949) and Im (1965) as function of age and BSA or age and height. The prediction formulas for MBC (L/min, BTPS) and MMF (L/min, BTPS) of the Korean children and adolescents as derived in this investigation are as follows: For male, MBC=[41.70+{$2.69{\times}Age(years)$}]${\times}BSA$$(m^{2})$ MBC=[0.083+{$0.045{\times}Age(years)$}]${\times}Ht$ (cm) For female, MBC=[45.53+{$1.55{\times}Age(years)$}]${\times}BSA$$(m^2)$ MBC=[0.189+{$0.029{\times}Age(years)$}]${\times}Ht$ (cm) For male, MMF= [0.544+{$0.066{\times}Age(years)$}]${\times}Ht$ (cm) For female, MMF=[0.416+{$0.064{\times}Age(years)$}]${\times}Ht$ (cm)
