Objective: The purpose of this study is to conduct maker-education for prospective child care teachers explore changes and for the results to be used as a basic data to study the utilization of maker-education. Methods: To that end, 36 prospective child care teachers attending nursery school applied to the maker-education program and to the curriculum of children's literature and play. The collected interview materials and student journals were qualitatively analyzed. Results: The results showed that prospective child care teachers started with mixed expectations and but then actively participated in worries classes with interest and had fun. Also, in the stage of sharing, they changed from having difficulty communicating with colleagues to developing an attitude of cooperation and unity through communication. In addition, it has been shown that from feeling the difficulties of planning, planning changes and modifications are directly related to their development and that they are quickly and wisely dealt with. Conclusion/Implications: It is recognized that there is a need for a follow-up study to verify the effect of this as meaningful implications are derived from the effects of positively accepting feedback, planning to attempt a step-by-step approach, and active attitude toward communication between colleagues.

This study investigate the influence of resilience on organizational commitment using social support as a mediating variable for kindergarten and childcare teathers. The subjects were 630 kindergarten and childcare teathers. The collected data were analyzed by Pearson's correlation as well as single and multiple regressions that used SPSS Win 19.0. The results were as follows: (1) The resilience was significantly associated with organizational commitment of kindergarten and childcare teachers. (2) The resilience was significantly associated with social support of kindergarten and childcare teachers. (3) The resilience was not significantly associated with organizational commitment of kindergarten and childcare teachers, controlled by social support. The results showed the social support was more important variable affecting organizational commitment of kindergarten and childcare teachers than the resilience. As a result, teachers have to be strengthened for support of social emotion that helps to control of their emotional condition and social evaluation that estimates their role positive under administration system.

Purpose: This study was done to evaluate the validity of the Korean - Child Development Review in screening children with developmental risks. Method: The participants in the study were 172 children aged 6-75 months old and their parents. Data were collected by questionnaire or interview. Korean Denver II and Bayley test were administered with K-CDR for validation of children who were referred for developmental assessment at D University Hospital or public health center. The data were analyzed using correlation, $X^2$ test, and cross tab analysis. Results: There was a significant relationship between the K-CDR and Korean Denver II. The correlation coefficients were .42 to .61 by developmental sector. The sensitivity and specificity of K- CDR were .84 and .66 respectively when "abnormal" with MDI of Bayley test defined as lower than 85 the score which was used as a diagnosis of developmental delay. The responses to 6 questions for parents showed significant differences according to 3 groups by developmental state. Parents of children in the developmental disability group more frequently checked problems from the 26 problem checklist about their children's development and behavior. Conclusion: The results show that K-CDR is valid and has good sensitivity and moderate specificity in screening developmental delay.

In the case of France which was successful in improving the ultra-low fertility rates of birth and South Korea, from the late 1980s, the birth rate fell continuously. In 1994, total fertility rate fell 1.66, but thanks to the active family policy of the government in the mid 1990s, it grew and maintained 2.0 average since the year 2008 until now. This study examined carefully how France was not classified as advanced welfare state, overcame the obstacles of low fertility problem in the socio-economic and institutional side and trying to get some suggestions from South Korea in which it of such problems in the field of low fertility.

We investigated the foodservice sanitation status of the childcare centers in Chungnam Asan area to provide the information for sanitation guidelines and checklist in various operation types of childcare centers. Self-completed questionnaires were collected from the directors of 95 centers: national-public 9 (9.5%), corporation 10 (10.5%), private 52 (54.7%), and home care 24 (25.3%) types. The analyzed results are shown in foundation type; the investigated items are about critical hygienic problems and safety recognition level, presence of sanitation guideline, demand of dietian's employment and the role, hygienic management and education level, and the present and future of sanitary facility and equipment. From this study we found that home care center, which had low capacity, was comparatively poor at sanitation status, the use of hygienic standard and guideline, and safety recognition level. In our opinion, the use and application of same sanitation standard to any type and size of center is not appropriate and rational. The reestablishment of the sanitation guideline and checklist considering the conditions of various operation types would be necessary. Also periodic hygienic education by hygenic professionals, continuous parents' attention and cooperation of related government organizations are needed for improvement of foodservice sanitation status of childcare centers.

We studied the feasibility of monitoring and controlling the manufacturing process of an infant formula with rice starch by testing in-process samples using rheology. We used DSC to first determine the gelatinization temperature of the rice starch, a key ingredient of this product. With this characteristic temperature and the process design known, rheological measurements were conducted on the in-process samples for detecting the presence and extent of gelatinization and retrogradation of rice starch; in-process samples were collected from the carbohydrate tank, after the homogenizer, and the finished product tank. The correlation between the rheological measurements on these samples and manufacturing performance proved that rheology is a very sensitive tool for monitoring the structural development of this infant formula during main process, and their influence on sterilization efficiency. We observed that the lower degree of gelatinization during main process, a shorter residence time in the finished product tank, and using caustic flush rather than clean-in-place additively lead to higher sterilization efficiency. These findings can be utilized for a rational design and analysis of the manufacturing process for infant formulas containing rice starch.

This study focused on the links between emotionality, interpersonal and intrapersonal intelligence, and behavior problems in a sample of 185 four- to five-year-old children in kindergarten and daycare centers in Seoul. All variables were measured by the teachers of surveyed children. Collected data were analyzed by Simple Regression and Hierarchical Multiple Regression. The main results of this study were as follows: Firstly, children's positive and negative emotionality each exerted negative and positive effects on their interpersonal and intrapersonal intelligence. Secondly, children's positive emotionality had a negative influence on internalizing behavior problems. On the other hand, children's negative emotionality had a positive influence on internalizing and externalizing behavior problems. Finally, effect of children's positive emotionality on their internalizing behavior problems was totally mediated by interpersonal and intrapersonal intelligence. On the other hand, effect of children's negative emotionality on their internalizing and externalizing behavior problems was partially mediated by their interpersonal and intrapersonal intelligence.

The objectives of this study were to assess food intake frequency and food behavior of infants and toddlers by using the Nutrition Quotient (NQ). A total of 368 subjects (infants 111, toddlers 257) in Ganghwa county were analyzed in this study. The NQ was examined using an NQ questionnaire, which consisted of 19 food behavior checklist items. The items were grouped into five categories: balance, diversity, moderation, regularity, and practice. All data were statistically analyzed by SPSS 20, and significant difference was evaluated by Student's t-test and $x^2-test$. The BMIs of infants and toddlers were $16.54kg/m^2$ and $16.01kg/m^2$, respectively. The frequencies of consumption of vegetables and fruits were higher (p<0.001) in girls and toddlers compared to boys and infants, respectively. Food behavior of meal regularity (p<0.001), breakfast eating (p<0.001), and chewing well (p<0.001) were also higher in toddlers compared to infants. Total NQ score of infants and toddlers were 62.05 and 64.91, respectively, which were within medium grade. The NQ score of toddlers was higher than that of infants (p<0.0.5). NQ score was positively correlated with parent's education, monthly income, age, and exercise. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and improve their nutritional status.

We examined the effects of family and home literacy environments on the vocabulary and reading abilities of 3 to 5-year-olds. In particular, SES was considered against home literacy environment. The sample consisted of 366 Korean children and their mothers. We found that the level of mother's education was related to the child's vocabulary test score. After controlling for family factors, home literacy environment score positively predicted children's performance both in vocabulary and reading tests. Magnitudes of differences between the two literacy groups (high and low home literacy environment) became larger in the children from relative lower income families. Magnitudes of differences for vocabulary and reading tests was strikingly large in the low-income group both in vocabulary and reading tests. These findings shed lights on the importance of parent education and family services for low-income families with preschool children.
