This study examined how parent-child attachment, parental involvement in child rearing and instruction for children's effective use of a smart device reflect on young children's smart device overuse behavior. We collected questionnaires from 196 parents with children attending early childhood education institutions for the survey. Frequency analysis as well as Person correlation coefficient and regression analysis were conducted using IBM SPSS 21.0 statistics. The results showed that 91% of targeted young children were using a smart device and 78% first used them before age 5. As for time of use hours, 43.9% used their smart device from 30 minutes to 1 hour on average. In addition, parent-child attachment and father's involvement in child rearing were found to be inversely correlated to young children's smart device overuse. The result of hierarchical regression analysis on parent factors influencing young children's smart device overuse behavior indicated that mothers' contact-seeking behavior to young children, mother's involvement in learning and instruction for children's effective use of a smart device at home had beneficial effects. This study analyzed parent factors that influenced young children's smart device overindulgence. In addition, the baseline data of this study will be utilized to develop programs for the prevention and therapy to solve the smart device overindulgence as well as to establish young children's guidelines for using a smart device.

Our study was conducted to examine the nest attendance of the Black-faced Spoonbill (Platalea minor) from 2015 to 2018 at two Islets located in Incheon, South Korea. We visited study sites in March-April and set up the remote sensor cameras at two breeding sites (Mae-do, Guji-do) to observe chick-rearing behavior. Mean nest bout length at Mae-do (female: 4.2 ± 0.1 hr, male: 4.0 ± 0.1 hr) was shorter than at Guji-do (female: 5.3 ± 0.2, male: 6.0 ± 0.3 hr), and trip duration at Mae-do (female: 4.4 ± 0.1 hr, male: 4.0 ± 0.1) was also shorter than at Guji-do (female: 7.0 ± 0.2 hr, male: 7.0 ± 0.3). Mean nest bout length and trip duration at both study sites decreased as chick rearing progressed. Males attended their nests during the daytime, and females attended their nests during the nighttime. Our results showed that females and males' duties were divided by the diel cycle, but the pattern of nest attendance could change depending on the environment of their breeding sites during the chick-rearing period.

The purpose of this study is to develop and evaulate improvement of marital relationship for immigrant women's husbands. They who play important role have much more resources than wifes in Korean society and establish a happier home through trying to adapt marital relationship. It needs to escape focusing on only immigrant education and program and have to extend to immigrants' family members including husband. The program procedure was implemented for 14 immigrant women's husbands every Friday for 2 hours from Feb, 2007 to Mar, 2007. To evaluating effects of program the pre test and post test was analyzed. The program was operated by researcher, center worker and volunteer who have much practiticing experiences about immigrants. The program of sessions is perception of intermarriage, understanding of wife's country culture, open communication, conflict resolution and child rearing attitude. As the results of the analysis, there were significant differences of the increases in the area of perception of intermarriage, open communication and child rearing attitude. Finally, this study suggests that understanding of wife's country culture and conflict resolution of the program be modified by future social work practitioners and researchers in order to make the program more effective.

Yongchonppong is liable to withering of leaf and it is lowering leaf value for the feed. In this respect, covering of the vinylon gauze over the feed has been carried out in the branch rearing system to sustain leaf value as itself. The covering of the vintlon gauze over Yongchonppong marks 7% and 9% increment of cocoon yield in dry season, spring rearing season, as compared to the non-covering of the vinylon gauze over Kaeryangppong and Yongchonppong, respectively. There was no significant differences in cocoon shell percentages of them. In more humid environment than average relative humidity in Korea the rearing results of "Yongchonppong" was improved by covering with vinylon gauze after feeding compared with the non-covered rearing. However, the vinylon guage covering was not effective for improving the rearing results of "Kaeryangppong". No effect of the vinylon gauze covering was seen in the area where it frequently rains and raining season lasts. In case of the non-covering of the vinylon gauze, Yongchonppong reduces repidly in the first three hours of exposure to the air, as compared to Kaeryangppong. The water content reductions rate of Yongchonppong in 6 hours of exposure to the air marks 7% to so when the dry vinylon gauze cover and 17 to 26% when the wet vinylon gauze covers, as compared to 58.8% of it for the noncovering of the vinylon gauze.f the vinylon gauze.

The objective of this study is to determine the structural relationships among the infant's temperament, father's involvement in child-rearing, and the infant's social and emotional behavior. To this end, research was conducted with 330 parents of infants aged 1 and 2 in 55 day care centers located in J city and I city, Jeollabukdo. Frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural model equation analysis were conducted using SPSS 21.0 and AMOS 21.0. First, the results of the structural model equation analysis showed that the infant's temperament had a negative correlation with leisure and guidance, while it had a positive correlation with activity and impulsivity, which are external manifestations of their social and emotional behavior. Father's involvement in child-rearing had a negative correlation with the adaptability and mood aspects of the child's temperament, and also with general anxiety, an internal aspect of his or her social and emotional behavior. Social and emotional behavior had a positive correlation with the approach avoidance aspect of the infant's temperament. Second, according to the results of the analysis of the route between the variables, infant temperament was found to be a significant route, having a statistically negative correlation with father's involvement in child-rearing. The results of this study showed that infant's temperament and father's involvement in child-rearing had effects on the infant's social and emotional behavior, and suggested the importance of having a proper understanding of the educational implications of the father's involvement in child-rearing, in terms of its effects on the infant's social and emotional behavior.

Objective: The growing consumers' interest on animal welfare has raised the request of products obtained by alternative rearing systems. The present study was conducted to assess the influence of housing system on gut and muscle morphology and on microbial load in rabbits reared under free-range (FR) and cage system (CS). Methods: A total of forty weaned (35 days of age) male Italian White breed rabbits were allotted according to the rearing system, and at 91 days of age were randomly selected and slaughtered for the morphological evaluation of tissue from duodenum and longissimus lumborum. Morphometric analysis of the villus height, villus width, crypt depth, villus height/crypt depth ratio, and villus surface was performed. The microbial loads on hind muscle was determined by total mesophilic aerobic count (TMAC), Escherichia coli and Enterobacteriaceae; whereas, total anaerobic bacteria count (TABC) and TMAC, E. coli and Enterobacteriaceae was determined on caecal content. Results: Rearing system did not interfere with the duodenum and muscle histomorphology in both rabbit groups. Similarly, microbial load of caecal content showed no significant differences on the TABC and TMAC. Conversely, significant difference was found for E. coli strains in caecal content, with the lower counts in FR compared to CS rabbits (p<0.01). Microbiological assay of muscle revealed significant lower TMAC in FR vs CS rabbits (p< 0.05). All rabbit meat samples were negative for E. Coli and Enterobacteriaceae. Conclusion: Free-range could be considered a possible alternative and sustainable rearing system in rabbits to preserve gut environment and muscle quality.

The nation's birthrate has been rapidly falling. The purpose of this study was to explore the factors related to low birthrate, by analyzing TV dramas dealing with childbirth and rearing. Content analysis is well suited to research probing widespread cultural notions or behavior. If any part or all of the dramas discussed an aspect of childbirth and rearing, we recorded verbatim quotes and paraphrased some specific points. Using the technique of multiple observers, inter rater as well as intra rater reliabilities were measured. The results showed that emergent themes in TV dramas on low birthrate are social environment, family context, and value changes. The conclusions and implications of these findings are discussed.

Ecological aspects of Cryptocercus kyebangensis life history were investigated via laboratory rearing and field observations. The number of antennal segments and head width were used to classify the first four instars. The results, which combine both the field collection and the laboratory rearing, indicate that eleven instars occur in C. kyebangensis. It supports the proposal on the number of instars of Park and Choe (2003c) based on field collections. A total of 388 nymps from 13 colonies were collected prior to winter to investigate overwintering stages. Of them,4％ (n = 17) were the second instars, 57％ (n = 220) were the third instars, and 39％ (n = 151) were the fourth instars, respectively. Thus, most of them overwinter in the third or fourth instars. The results indicate that young nymphs of C. kyebangensis have to reach at least 3rd or 4th instar to survive low temperature environment of winter. According to seasonal dynamics of populations, C. kyebangensis reaches adulthood in the summer of the fourth or fifth year (4-5 yr span) after their birth.

The purpose of this study was to examine the mediating effects of self-esteem on the relationship between adolescents' family environment(parent's child-rearing attitude, family cohesion), peer environment(quality of peer relationship, peer bullying) and career maturity. The subject of this study were students of third grade of middle school who reside in Seoul. 425 self reported questionnaires were used for final analysis. Findings of this study indicated that family environment of adolescents directly affected peer environment. Family environment and peer environment of adolescents directly affected self-esteem. Self-esteem was more highly affected by peer environment than family environment. Adolescents' self-esteem directly affected career maturity. The structural equation modeling showed that self-esteem mediated the relationship between family environment, peer environment and career maturity.
