Vitamin D is an essential component of bone and mineral metabolism; its deficiency causes growth retardation and skeletal deformities in children and osteomalacia and osteoporosis in adults. Hypovitaminosis D (vitamin D insufficiency or deficiency) is observed not only in adults but also in infants, children, and adolescents. Previous studies suggest that sufficient serum vitamin D levels should be maintained in order to enhance normal calcification of the growth plate and bone mineralization. Moreover, emerging evidence supports an association between 25-hydroxyvitamin D (25[OH]D) levels and immune function, respiratory diseases, obesity, metabolic syndrome, insulin resistance, infection, allergy, cancers, and cardiovascular diseases in pediatric and adolescent populations. The risk factors for vitamin D insufficiency or deficiency in the pediatric population are season (winter), insufficient time spent outdoors, ethnicity (non-white), older age, more advanced stage of puberty, obesity, low milk consumption, low socioeconomic status, and female gender. It is recommended that all infants, children, and adolescents have a minimum daily intake of 400 IU ($10{\mu}g$) of vitamin D. Since the vitamin D status of the newborn is highly related to maternal vitamin D levels, optimal vitamin D levels in the mother during pregnancy should be maintained. In conclusion, given the important role of vitamin D in childhood health, more time spent in outdoor activity (for sunlight exposure) and vitamin D supplementation may be necessary for optimal health in infants, children, and adolescents.

Purpose: The purpose of this study was to explore the experiences of nursing college students who attended delivery practices at midwifery clinic. Methods: This was a qualitative study using focus groups. Data were collected by group interviews with a total of 12 students who observed natural childbirth at midwifery clinic. Data were analyzed through Colaizzi's method in which meaningful statements were extracted. Results: The meanings of experiences were identified five theme clusters from thirteen themes and thirty-one sub-themes. The five theme clusters were 'ultimate process of natural childbirth', 'allowed birth', 'role recognition of the midwife', 'positively changed perception', and 'barriers'. Conclusion: This study showed that observation of delivery at midwifery clinic was helpful for nursing students in terms of positive impression about natural childbirth with maternal and baby being centered. Nursing students expressed value and concern about delivery at midwifery clinic. Further in-depth study of natural childbirth in terms of husband and family perspective is required. For quality improvement of maternity nursing care, natural childbirth process needs to be included in nursing care at hospitals as well as students' clinical practicum.

The aim of the current study is to examine the effects of mothers' home management ability on school-aged children's time and life management skills through the mediation effect of children's self-regulation. Study subjects were 317 5- and 6-grade children at elementary schools located in Seoul and Gyeonggi area and their 317 mothers. The findings were as follows. First, in the SEM model of predicting children's time management skill, greater mothers' home management ability significantly predicted better time management skills among their children. Second, mothers' home management ability also indirectly affected children's time management skill through its significant effects on children's self-regulation. The test yielded a significantly mediation effect of self-regulation. Children's self-regualtion was strongly related to time management skills. Third, in the SEM model predicting children's life management skills, maternal ability of home management again directly predicted greater life management skills of their children. However, mediation of self-regulation was not statistically significant. The findings suggested the important role of mothers' home management ability in instilling and modeling self-regulation and self-management skills of school-aged children.

Objectives: A descriptive correlational study was designed to examine the relationship of anger to psychosomatic symptoms. In addition, this study investigated the mediating effect of parental attachment in relation to anger and other variable. Methods: Data were collected from 112 subjects in grade 4 or 6, and descriptive statistics, Pearson correlation coefficient, and hierachical multiple regression were used with SPSS/PC 18.0 program to analyze the data. Results: There was a significantly positive effects between state-trait anger and psychosomatic symptoms. Father attachment negatively correlated state-trait anger and psychosomatic symptoms. Also, mother attachment negatively correlated state anger and psychosomatic symptoms. However, maternal attachment was not significantly associated with trait anger. Parental attachment had a significant mediating effect in relation to state-trait anger and psychosomatic symptoms. Conclusions: For the effective management of multi-cultural children's psychosomatic symptoms, programs including parental attachment increasing strategies should be established. These programs can increase parental attachment security which is mediator role between anger and psychosomatic symptoms.

Objectives: This study was conducted to provide data in order to develop effective family planning programs by analyzing the factors which affect contraceptive use among women in Ethiopia. Methods: The community health survey was conducted on women of childbearing age. The research model was developed based on Andersen's Model. A total of 320 respondents were analyzed through Chi-square analysis, t-tests and logistic regression analysis. Results: Contraceptive prevalence rate was 43.1% and most of them were using modern and short-term methods. Among three factor categories, the need factor(unwanted pregnancy experience) was revealed as the most important factor, following enabling factor which was knowing the FP services in health center. Conclusions: These results lead to several conclusions. First, the results imply that programs should focus on women who are in the over 30yr. as well as the poorer economic group and urban residents. Second, to improve the effectiveness of the program, it is important to help them to be motivated themselves and to promote knowledge on various methods. Third, in terms of service delivery, community health workers are expected to take a crucial role. To improve the availability of services, they should provide practical services as those in health center.

Previous infant feeding guidelines recommended a delayed introduction of solids to beyond 6 months of age to prevent atopic diseases. However, scientific evidence supporting a delayed introduction of solids for prevention of atopic diseases is scarce and inconsistent. Current evidence does not support a major role for maternal dietary restrictions during pregnancy or lactation in the prevention of atopic disease. In studies of infants at high risk of developing atopic disease, there is evidence that exclusive breastfeeding for at least 4 months compared with feeding intact cow milk protein decreases the incidence of atopic dermatitis, cow milk allergy, and wheezing in early childhood. For infants at high risk of developing atopic disease who are not breastfed exclusively for 4 to 6 months, there is modest evidence that atopic dermatitis may be delayed or prevented by the use of extensively or partially hydrolyzed formulas, compared with cow milk formula, in early childhood. There is no convincing evidence that a delayed introduction of solid foods beyond 4 to 6 months of age prevents the development of atopic disease. For infants after 4 to 6 months of age, there are insufficient data to support a protective effect of any dietary intervention for the development of atopic disease.

In order to provide the basic data on an education program for successful breast-feeding, the nutrition knowledge of and attitudes toward breast-feeding and the factors associated with infant feeding decision among male and female college students were investigated. The majority of students had correct knowledge of the maternal-infant bonding through breast-feeding and knew more about baby-centered benefits than about mother-centered benefits of breast-feeding. Students' attitudes toward breast-feeding were not so positive as expected, and male students had more positive attitudes toward breast-feeding than female students had. 54.8% of students answered to practice breast-feeding longer than 3 months. Nutrition knowledge scores and attitude scores were significantly higher in the breast-feeding decision group than in the formula-feeding decision group. The students residing in a rural community decided breast-feeding significantly more than the students residing in an urban community. It was concluded that nutrition knowledge about the breast-feeding played a significant role in deciding infant feeding method. In order to increase breast-feeding decision rates among college students, the education program may need to focus on understanding of correct nutrition knowledge about the benefits of breast-feeding. Also it would be important to have male students participated in education program.

The maternally inherited mitochondrial DNA (mtDNA) D-loop region is widely used for exploring genetic relationships and for investigating the origin of various animal species. Currently, domestic ducks play an important role in animal protein supply. In this study, partial mtDNA D-loop sequences were obtained from 145 samples belonging to six South-East Asian duck populations and commercial duck population. All these populations were closely related to the mallard duck (Anas platyrhynchos), as indicated by their mean overall genetic distance. Sixteen nucleotide substitutions were identified in sequence analyses allowing the distinction of 28 haplotypes. Around 42.76% of the duck sequences were classified as Hap_02, which completely matched with Anas platyrhynchos duck species. The neighbor-joining phylogenetic tree also revealed that South-East Asian duck populations were closely related to Anas platyrhynchos. Network profiles were also traced using the 28 haplotypes. Overall, results showed that those duck populations D-loop haplotypes were shared between several duck breeds from Korea and Bangladesh sub continental regions. Therefore, these results confirmed that South-East Asian domestic duck populations have been domesticated from Anas platyrhynchos duck as the maternal origins.

This ethnographic case-study explores the daily experiences in child-rearing and education among Korean full-time housewives. For this purpose, 11 full-time housewives in their thirties and forties from the middle class were interviewed with an unstructured questionnaire. The findings are as follows: Full-time housewives tend to assume the full responsibility for child-caring and education. Their time is structured around the schedules of caring children and participating in educational programs for children. The most demanding tasks for them include preparing for a preschool, getting the children ready for school, rendering supports for children's schools, extra curricular education, and arranging and offering gift money to teachers. They feel that their husbands do not provide enough supports for child-caring and education. Despite all the negative experiences, Korean full-time housewives put in whatever they have to make sure their children's well-being and to provide the best education possible for their children; the maternal identity plays a role of the utmost importance in them.

This study was conducted to identify the factors that affect the output of health conters. An analystical model employed in this study was developed by modifying 'input-output model' and 'organizational behavior model'. Data were collected form two source; the 1995 report of thealth center which was submitted to the Ministry of Health and Welfare and a mail survey questionary of officers at health center, including 66 directors and 1,768 staffs of the health centers in southern region. The major findings are as follows: That analysis has identified the factors associated with dependent variables: medical services provided by the health center and health program performance(HPP). The number of primary medical facilities was negatively associated with health center performance while the number of staffs, job satisfaction, and professional background of health center directors were positively associated. These independent variables accounted for 40.1% of the variance of dependent variables. The variance of HPP was significantly explained by the number of health subcenter and primary health post, priority level of public health program by hief executive officers(CEOs) and legislator. A significant relationship was found between leadership types of health center directors and the performance of maternal and child health program. Considering these results, the authors suggested that the role in medical care service of health center in the should be rearranged at local level because medical care service of the health center is competing with primary medical facilities in the same region. It is also suggested that educational efforts be made to improve leadership of the health center directors and concern with public health program by the CEOs and legislators of local governments.
