In this study, tissue equivalency (TE) of a newly developed epoxy-based phantom to 3-5 years child's tissue was investigated in paediatric energy range. Epoxy-based TE-phantoms were produced at different glandular/adipose (G/A) ratios of 17/83%, 31/69%, 36/64% and 10/90%. A procedure was developed in which specific amounts of boron, calcium, magnesium, sulphur compounds are mixed with epoxy resin, together with other minor substitutes. In paediatric energy range of 40-60 kV_p half-value layer (HVL) values were measured and then Hounsfield Units (HU) were determined from Computed Tomography(CT) scans taken in the X-ray energy range of 80-120kV_p. It is found that radiation absorption properties of these phantoms in terms of the measured HVL values related to linear attenuation coefficients (µ) are very well mimicking a 3 years child's soft tissue in case a ratio of 10/90%G/A. Additionally, the HU values of phantoms were determined from the CT scans. The HU = 47.8 ± 4.8 value was found for the epoxy-based phantom produced at a ratio of 10/90%G/A. The obtained HVL and HU values also support the suitability of the new epoxy based-phantom produced at a ratio of 10/90%G/A for a satisfactory mimicking a 3 years child's soft tissue by 5%. Thus they can have a potential use to perform the quality controls of medical X-ray systems and dose optimization studies.

The primary purpose of this study was to examine what social behaviors are valued within Korean culture for children of preschool age. The sample consisted of 40 mothers of preschool children and 40 preschool teachers. Two instruments were used : an open-ended interview and the Preschool Behavior Q-sort(Baumrind, 1968). Korean mothers and preschool teachers emphasized social behaviors based on cultural values. However, social behaviors that Korean mothers and preschool teachers emphasized were not, for the most part, the expected behaviors about respect for authority or obedience. Rather, they valued considerateness, politeness, mastery behaviors that represent another aspect of traditional values.

Participants were 272 teachers from kindergartens and child care centers who responded to 2 survey questionnaires: translated and revised versions of Laub's (1999) Servant Organizational Leadership Assessment(SOLA) and Jorde-Bloom's(1989) Early Childhood Job Satisfaction Survey(ECJSS). Components of SOLA were values people, develops people, displays authenticity, builds community, provides leadership, and shares leadership; components of ECJSS were co-worker relationships, administrator relationship, job itself, working environment, possibility of rewards/promotions, feelings about the organization. Data were analyzed by SPSS WIN computer program, Pearson's correlation and multiple regression analyses. Relationships were found between servant leadership of the early childhood educational institution and job satisfaction. Components of perceived servant leadership that predicted job satisfaction were 'develops people', 'displays authenticity', 'values people' and 'provides leadership.'

this study examined behavioral inhibition in relation to their mothers' value and attitudes toward children's inhibited behavior as a function of child sex. Data were collected via questionnaires from a sample of 483 7-to 8 year-olds and their mothers. Results showed that there were no significant differences in mother's value mothers' attitudes toward child behavior and child's behavioral inhibition according to child sex. However it was found that mothers' value was associated with attitudes toward child inhibition and behavioral inhibition in 7-to 8 year-olds girls. more specifically mothers who hold high traditional values were not concerned about girls' inhibited behavior and thus in turn had more inhibited girls. But the associations were not found for boys. the results indicated cultural effects on parenting attitudes as well as child inhibition.

This study examined the effects of support systems and traditional value beliefs about the role of women on the parenting stress of dual-career mothers. The subjects were 203 employed mothers with one child 4- to 36-months of age. The influential independent variables affecting parenting stress listed in order of significance were satisfaction with child care, value placed on traditional maternal roles, sex of child, and cost of child care. Contrary to the researchers assumptions, social support systems had no effect on parenting stress. The results of this study have implications for formal and informal support systems for employed mothers with young children.

This study evaluated the evaluate nutrient knowledge of child care teachers and assessed the nutritional level of snacks served in 18 child care centers in Tean-Gun. The survey sample was 18 child care teachers working in 18 child care centers of Tean-Gun. The questionnaire requested information about demographic factors, nutritional knowledge, management status of snacks, and the kinds and serving size of snacks served for 1 week. Data were analyzed using SPSS for windows(version 12.0) and nutritional values were assessed using Can-pro 2.0. The mean score of teachers' nutritional knowledge was 22 out of 30 points. The scores were low in the questions regarding the ease with which Ca and re deficiencies can be developed in infants. The contents of most nutrients supplied from the snacks exceeded 15% of RI(Recommended Intake) but there were significant differences in the contents of energy (p<0.05), protein (p<0.05), fat (p<0.05), carbohydrate (p<0.05) and calcium (p<0.001) between the child care centers. Especially, the difference of calcium between the child care centers was 344.84 mg. These results indicate that a program of relevant nutritional education focusing on snacks needs to be developed for child care teachers, with a special recognition on correct calcium level.

Child is a being and provides the genetic continuity of parents and society, and therefore the fitness of these children for survival, growth and development towards reproduction, is of significance to parents and society. The aim of health care for high-risk children is not only to minimize or eliminate health problems, but also to optimize their fitness. Considering that the health care of children is influenced by available resources of parents and society, and sociocultural values and paradigms in a given environment of evolutionary adaptedness (EEA), child health care professionals need to understand factors affecting the optimal fitness of children with risks. This paper introduces a new integrated theory for health care in high-risk children, entitled, Health for Optimal Fitness of High-Risk Children. Five main components were identified with associate concepts or midrange theories affecting heath for optimal fitness of high-risk children; EEA, optimal fitness, health problems, investment resources, and anthropological values. It may provide an integrated perspective on health of high-risk children in both the proximately biomedical approach and ultimately evolutionary approach as optimizing their fitness. Further study is needed to develop substantial statements between components with existential examples.

The purpose of this study was to identify current housing status and housing awareness such as housing values, satisfaction, and preferences among households with one child. Data were obtained from a questionnaire completed by both husbands and wives living in metropolitan area and aged between 25 and 45. Selected variables were the age, education level, and employment status of housewives, ideal number of children, monthly income, plan to give birth, and so on. Using purposive sampling method, five hundred questionnaires were administered and 360 questionnaires were analyzed. In accordance with the questions related to housing values, housing satisfaction of respondents was examined. In order to compare the housing values, preferences, and satisfaction among diverse variables of respondents, mean, t-test, F test, Duncan's multiple range test, $x^2$ test, and factor analysis were used. The major findings of this study are as follows: First, there were significant differences in current housing type, tenure type, and floor area according to housewives' age, education level, monthly income, and plan to give birth. Interestingly, households not having a plan to give birth in the future were living in larger house than the households having a plan to give birth. Second, housing values of households with one child were divided into 4 factors-environmental comfort, economy and convenience, social status symbolism, and adequacy of space planning. Items related to privacy showed the biggest difference between housing values and housing satisfaction. Third, most of the respondents wanted larger house than current housing. However, the need for quality of housing including floor area and amenities was significantly higher among households not having a plan to give another birth than households having a plan to give birth in the future.
