The purpose of this research is to compare the attitudes of female students in Korea toward science with the child-rearing attitude of their parents they perceived and their sex-role identity. The participants in this study were 374 female middle- and high-school students, chosen randomly from Seoul and Gyenggi-do in South Korea. We used three different forms of questionnaires in this research: "Scale of Parents' Child-rearing Behaviors Perceived by Teenagers", "Korea Sex-role Survey", and "Attitude Toward Science Measurement." The significant results were acquired after we had analyzed the comparison of the attitude of female students toward science with their perception on their parents' child-rearing attitude, especially on their fathers. The fathers' "monitoring" and "over-expectation" factors affected the attitudes of female students toward science; on the other hand, any child-rearing attitudes of their mothers did not influence their attitudes toward science. We also analyzed the attitudes of female students about science based on their sex-role identities. In consequence, we found that meaningful differences existed in four types of gender-role identity: androgyny type, masculinity type, femininity type and undifferentiated type. In particular, the androgyny type was characterized by a higher score in attitude toward science compared with the undifferentiated type.

Predictors of parenting efficacy were examined in 448 college-educated mothers of kindergarten children. The mothers completed measures of maternal self-efficacy, child temperament, and father's child-rearing involvement. Higher parenting self-efficacy was observed in mothers of daughters, older siblings, less emotional, more active, and more sociable children, and among mothers who perceived higher levels of father's child-rearing involvement. Of the father's child-rearing involvement variables, guidance of socially appropriate language and behavior was the best predictor of mothers' parenting efficacy.

Total length and body weight of grey mullet were 6.4cm and 2.1g, respectively at the beginning of the experiment. After 60 days of rearing, body weight of the mullet(363%) was significantly higher in freshwater group than that (187%) in seawater group. However, the condition factor showed no significant differences between seawater (9.0%) and freshwater (8.8%) groups. Survival of the mullet was 98.3% and 64.3% in seawater and freshwater groups, respectively.

The purpose of this study was to examine the creative behavior characteristics of 4-5 year olds and to investigate the relationship between these characteristics and the mothers' supportive child-rearing behaviors. The subjects were 125 pairs of young children and their mothers in Seoul and Gyeonggi-do. The major results of this study were as follows. First, young children were rated to show uniqueness, openness, sensitivity, playfulness, and perseverance as creative behavior characteristics by their teacher. There were no significant differences between creative behavior characteristics of boys and girls. Second, the more mother used supportive child-rearing behaviors, the higher their children's creative behavior characteristics were estimated.

The purpose of this study was to investigate relationships between adolescent's behavioral inhibition and social anxiety focused on the moderating effects of perceived parental rearing behaviors. Subjects were 749 7th through 9th grade students attending schools in Seoul and Gyeonggi Province. Major findings were that (1) boys' and girls' behavioral inhibition was an important factor predicting social anxiety; and (2) perceived parental rearing behaviors played the role of moderating variables on the influence of behavioral inhibition of boys' and girls' social anxiety. In the boys' group, perceived intrusion had a moderating effect on the relationships between behavioral inhibition and social anxiety; in the girls' group, perceived warmth and perceived granting of autonomy acted as moderating variables on social anxiety.

Viral nervous necrosis (VNN) is a serious disease of sevenband grouper Epinephelus septemfasciatus in Korean aquaculture farms. However, we suggest the following preventative methods for hatcheries: 1) disinfecting rearing water, 2) selecting spawners via ELISA and PCR, 3) selecting eggs via PCR, 4) disinfecting fertilized eggs, and 5) proper facilities management. When these methods are implemented, nervous necrosis virus (NNV)-free fish are produced because vertical and horizontal transmission is prevented. However, horizontal transmission of NNV through rearing seawater sourced from the environment during grow-out stages in sea cages can still occur. Live NNV vaccines with a low rearing temperature or Poly(I:C) immunization are very effective at preventing horizontal transmission of NNV in rearing farms. Furthermore, even after VNN is contracted, fish mortality can be reduced by administering Poly(I:C).

The purpose of this research was to examine variables contributing to the father's role performance. The study has been designed to measure the quantitative(i.e. amount of involvement) and the qualitative(i.e. depth of affection/care) values in their modes of child-rearing practices by taking a clouter look at the father's views on their careers and on offspring. Subjects were 516 fathers of school-age children. Analyzing the factors that determine the quantitative and qualitative aspects of child-rearing practices by the fathers, the sense of fulfillment/value in life is the decisive factor behind the affection(i.e. qualitative) in the child-rearing practices. The resets indicated that the father's perceptions on their careers and on their children constitute the critical factors behind the qualitative and quantitative aspects of child-rearing practices, albeit holding such factors as the parents'working hour or as mothers with outside jobs under control.

The main purpose of this study was to examine the main and interaction effects of inhibition, day-care experiences and mothers' controlling child-rearing behavior on young children's social withdrawal in peer situations. A total of 62 young children(34 boys; 28girls) enrolled in day-care center and their mothers participated in this study. Data on child inhibition and parenting were gathered via questionnaires whereas the quality of day-care and social withdrawal were observed in the day-care center. As results, the quality of day-care and mothers' controlling child-rearing behavior were negatively related to social withdrawal. Further, both day-care entry age and the quality of day-care were served as an intervening variables between child inhibition and social withdrawal.

The purpose of this study was to explore the ideas about Korean-American mother's school-age child rearing that are represented on internet community. The method used for this study was content analysis and the data consisted of articles about Korean-American mother's school-age child rearing on a internet community bulletin board during 1 year in 2008. It was found that these articles dealt with problems of practice in interfacing between home and social institutions(Especially school), teaching, counseling, nurturing and disciplining. For example, 831 articles put great emphasis on interfacing between home and social institutions, 339 on teaching, 268 on counseling with children. From these results, we might conclude that many Korean-American mothers gave their children school related care.
