The purpose of this study was to analyze the effects of workers' human resource development and their recognition of human resource on-the-job satisfaction. A sample of 4,727 workers that was selected from Korea Labor Panel Data was analyzed by t-test and multiple regression, and was tested by causal effects among related variables. The major findings were as follows: First, the workers' recognition of their job performance level vs. educational attainment was affected by their annual income, job status, educational attainment, gender, and experiences of human resource development. Second, the workers' job satisfaction was affected by gender, age, educational attainment, health status, job status, annual income, experiences of human resource development, recognition of their job performance level vs. educational attainment, and recognition for their job availability. Third, the factors that had a causal effect on workers' job satisfaction were educational attainment, gender, age, health status, annual income, and experiences of human resource development. Above all, workers' educational attainment had a strong direct effect on job satisfaction, and annual income had a strong indirect effect on it. From these findings, it can be concluded that workers' effort and trial for development and investment of human resource played an important role in increasing job satisfaction.

Objectives: The objective of this study was to provide an actual data for parents of infants about growth developmental status of brestfed infants. Methods: The subjects were 150 brestfed infants of 5, 6, 7 months as a primary nutrient source. Results: 1) The mean score of growth developmental status of subjects were $8.6({\pm}1.15)$ and $9.5(({\pm}.58)$ at the highest points of 10.0. 2) The growth status was signifant difference according to feeding type(t=-2.076, p=.040), development status was signifant difference according to infant age(F=8.272, p=.000). Conclusions: The main point infants breast milk is very beneficial to infants growth development status. This result can be used as an important guide for nurses to teach the infants parents.

This study examined the mediating effect of maternal abuse and neglect on the relationship between socioeconomic status and preschoolers' social behavior. A total of 702 mothers with 3-year-olds(353 boys and 349 girls) and the children's teachers, all of whom reside in Seoul, participated in the study. Socioeconomic status was measured by maternal educational level and monthly household income. Maternal abuse and neglect were assessed by asking mothers to complete the Parent-to-Child Version of the Conflict Tactics Scales. Both mothers and teachers completed the Preschool Social Behavior Scale in order to evaluate prosocial behavior and aggression. The results indicated that both socioeconomic status and maternal abuse and neglect were significantly associated with preschool children's prosocial behavior, and socioeconomic status was significantly and negatively related to aggression. Furthermore, a structural equation model confirmed the mediating effect of maternal abuse and neglect on the relationship between socioeconomic status and preschool children's prosocial behavior, suggesting the need for interventions focusing on improving positive parenting and decreasing negative parenting to promote prosocial behavior.

The pale, soft, exudative (PSE) syndrome lowers storage quality and consumers acceptability in the particular meat. With the increase in the consumption of parted chickens in Korean meat consumption trade, a parallel increase in the concern over the PSE status of chickens have been noticed. The present study focused on the PSE status of broiler's breast to investigate the effects of different degrees of PSE on its quality and storage characteristics. A total of 46 broiler chickens of 35 days old averaging 1,251-1,350 g were selected for the study. Breast separated and skin was removed. The breast meat was stored at $4^{\circ}C$ for 3 days and were analysed for pH, lightness, yellowness, redness, shear force, water-holding capacity (WHC), cooking loss, Thiobarbituric acid reactive substances (TBARS) and Volatile basic nitrogen (VBN) on day 1 and 3 during the storage. Increase in the degree of broilers breast PSE during storage caused fall in pH and shear force and increase in lightness, cooking loss, TBARS, VBN. Broilers breast PSE status confirms the actual pale soft and exudative nature of meat.

The purposes of the study were to analyze nutritional status, psychosocial stimulation, and factors affecting the cognitive development of preschool-age children. This study was conducted in the Village of Babakan, Sub-District of Dramaga, Bogor Regency, West Java. This cross-sectionally designed study was conducted with mothers who had preschool children aged 3-5 years as respondents. Fifty-eight children were included. The distribution of mother's educational level was quite diverse, and the largest percentage (44.8%) had senior high school education. Approximately 78% of the family income per capita was classified into the non-poor category and 22.4% into the poor category. The average mother's nutritional knowledge score was $76.7{\pm}2.5$ (moderate category). Most of the preschool children (84.4%) had psychosocial stimulation scores in the moderate category (30-45). The nutritional status of children showed that 15.5% were underweight, 5.2% were wasted, 3.4% were severely wasted, and 19% of the children were in the short and very short categories (stunted). The stepwise regression results showed that psychosocial stimulation (P < 0.001), participation in early childhood education (P = 0.002) and nutritional status based on the height index for age (P = 0.028) had a positive and significant effect on cognitive development of the preschool children (adjusted $R^2$, 0.434; P = 0.028).
