  • The QTL(quantitative traits loci) linkage mapping of Hanwoo (Korean Cattle) chromosome 6 for daily gain and marbling score was performed using 378 individuals from 18 paternal half-sib families in Hanwoo. Hanwoo chromosome 6 were mapped to total length of 394.2 cM between 28 microsatellite loci using 36 microsatellite primers of BTA 6 linkage group. The QTL analysis for daily gain in Hanwoo showed 8 microsatellite loci (BM3026-5.66, EL03-5.58, BM4311-5.29, ILSTS035-4.50, BMS1242-4.37, BM1329-3.67, BM415-3.11, BMS2460-3.03) in larger than LOD score 3.0. Based on the QTL analysis for marbling score, LOD scores of 12 microsatellite loci (BM415-8.88, BM3026-7.15, ILSTS093-5.45, ILSTS035-4.91, EL03-4.69, BMS690-4.52, BM1329-4.43, BMS511-3.74, BMS1242-3.66, BMS518-3.65, BM4311-3.41, BMC4203-3.36) were found larger than 3.0.

  • Records on weaning (3803) and yearling weight (2990) of beef cattle (Bibos banteng) from the Bali Cattle Improvement Project were examined. A mixed model analysis involving all main non-genetic effects (village, year of birth, season of birth, age of dam, sex of calf, all significant interactions and age at weighing as a covariate) as fixed effects and sire nested within village as a random effect was undertaken. Variance components were estimated by Henderson's Method III. Paternal half-sib components of variance and covariance were used to estimate heritabilities of weaning and yearling weights, as well as their genetic and phenotypic correlations. Heritability estimates ($\pm$ standard error) obtained by Henderson's Method III for weaning and yearling weights were $.11{\pm}.03$ and $.13{\pm}.04$, respectively while the phenotypic and genetic correlations were estimated as .32 and $.64{\pm}.10$, respectively. The parameters estimated in this study were at the lower end of the range of reported values from various breeds. It is concluded that further information should be gathered to assist in estimating genetic parameters for other economic traits of Bali beef cattle and to provide more accurate estimates for weaning and yearling weights. These parameters should then be used to formulate a selection program to enable the genetic improvement of Bali Beef cattle.

  • Objective: The purpose of this research was to examine the effects of parents' childhood attachment representations and parenting behavior in developing early childhood self-regulation, a developmental skill. Methods: This research was conducted with 171 preschoolers, 171 parent couples, and 22 teachers of 5-year-old classes in kindergartens and children's houses in Seoul. Results: First, there was significant correlation among parental childhood attachment representations, parenting behavior, and child self-regulation. Second, parental attachment representations and parenting behavior were shown to affect self-monitoring, a subvariable of self-regulation, and were influenced by maternal independence-oriented parenting behavior, maternal attachment representation, and parental attachment representation. As factors affecting self-control, a subvariable of self-regulation, they were influenced by maternal attachment representation, and maternal and paternal affectionate parenting behavior. Lastly, as factors affecting self-control, they were influenced by attachment representation to parents of origin, maternal affectionate parenting behavior, and maternal independence-oriented parenting behavior. Conclusion: This research revealed that parental childhood attachment representations and parenting behavior are important variables affecting the development of self-regulation in preschoolers. This finding can be used as basic data for parent education content to help preschoolers grow healthier and happier and as basic data for a program to improve parent-child attachment.

  • Objective: This study examined whether the effects of fathering on school children's effortful control would be moderated by fathers' and mothers' own effortful control. Methods: The sample included 371 fourth grade children (47% boys) and their parents. Father's positive and negative parenting behaviors, parents' own effortful control and children's effortful control were assessed. Data were analyzed using hierarchical multiple regression in SPSS 18.0. Results: Parents' effortful control appeared to moderate the effect of fathering on children's effortful control. More specifically, parents' high levels of effortful control increased the effects of positive fathering on children's effortful control. Conclusion: Findings indicated that parents' effortful control tended to increase the effects of positive fathering (and lower the effects of negative fathering). This supports the importance of parents' effortful control in the development of school children's effortful control.

  • Purpose: The purpose of this study was to review the literature on paternity leave and family health over the last 10 years. Methods: Nine studies that met the criteria were selected from sixty-four studies. General characteristics, study design, and major findings about paternity leave were analyzed using an established analysis framework. Results: From the integrative review, paternity leave was found to affect the health of fathers, mothers, and children, as well as family health and gender equality. The father's paternity leave resulted in an increase in mothers' breast feeding rate, a decrease in maternal depression, a reduction in parenting stress, a reduction in all-cause mortality of men, feelings of instinctive paternal love, increased parenting, skills, and positive parent-child relationships. It was interpreted that paternity leave had a positive effect on the mental and physical health of individual members of the family. Conclusion: This study provides the basic data on the health effects of father's parental leave on the family system in a holistic view. In addition, this study proposes the direction of paternity leave and family health research and policy needs.

  • This study examined the relationship between family meal time and emotional well-being for 5,186 fathers who were employed and had at least one child aged under 18 for the years 2009 and 2014 by analyzing their time diaries. In doing so, changes in time spent by fathers on family meals between 2009 and 2014 were also examined along with the factors associated with the amount of meal time for each year in order to understand ways to increase paternal participation in family meals. Analytic results showed that a father's family meal time had a positive association with his time use and life satisfaction; however, fathers who spent more than 40 minutes a day having meals with the family reported the highest score in time use and life satisfaction. The amount of time fathers spent on family meals increased from 38 minutes in 2009 to 43 minutes in 2014, whose change turned out to be mainly attributable to something more than the compositional change in the population between the two years, such as growing public awareness or cultural acceptance of the value of family meal. Fathers in dual-earner households tend to have longer family meal times; however, different factors were associated with their family meal times in 2009 and 2014. Policy implications are discussed in light of the government-initiated dining table education campaign to increase family meal time for the sake of children's character education at home.

  • This study examined the relationship among parenting behaviors, children's perfectionism and achievement motivation, using a sample of 338 fifth and sixth graders. The participants completed questionnaires on parenting behaviors and their perfectionism and achievement motivation. Data were analyzed by factor analyses and multiple regression analysis. Both boys and girls had higher achievement motivation when they perceived higher parental levels of acceptance, and girls showed higher achievement motivation when they perceived higher maternal control/over-expectation. Boys who exhibited self-oriented and socially prescribed perfectionism and girls who exhibited self-oriented perfectionism showed higher achievement motivation. Boys had higher self-oriented and socially prescribed perfectionism when perceiving higher parental acceptance and control/over-expectation. Girls showed higher self-oriented perfectionism when perceiving higher parental acceptance and control/over-expectation, and they showed higher socially prescribed perfectionism when perceiving higher paternal control/over-expectation and maternal acceptance and control/over-expectation. It was revealed that both boys' and girls' perfectionism tended to play mediating roles between parenting behaviors and achievement motivation.

  • Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder that is caused by the lack of expression of paternally inherited imprinted genes on chromosome 15q11-q13. This syndrome has a characteristic phenotype including severe neonatal hypotonia, early-onset hyperphagia, development of morbid obesity, short stature, hypogonadism, learning disabilities, behavioral problems, and psychiatric problems. PWS is an example of a genetic condition caused by genomic imprinting. It can occur via 3 main mechanisms that lead to the absence of expression of paternally inherited genes in the 15q11.2-q13 region: paternal microdeletion, maternal uniparental disomy, and an imprinting defect. Over 99% of PWS cases can be diagnosed using DNA methylation analysis. Early diagnosis of PWS is important for effective long-term management. Growth hormone (GH) treatment improves the growth, physical phenotype, and body composition of patients with PWS. In recent years, GH treatment in infants has been shown to have beneficial effects on the growth and neurological development of patients diagnosed during infancy. There is a clear need for an integrated multidisciplinary approach to facilitate early diagnosis and optimize management to improve quality of life, prevent complications, and prolong life expectancy in patients with PWS.

  • Passive exposure to tobacco smoke significantly contributes to morbidity and mortality in children. Children, in particular, seem to be the most susceptible population to the harmful effects of environmental tobacco smoke (ETS). Paternal smoking inside the home leads to significant maternal and fetal exposure to ETS and may subsequently affect fetal health. ETS has been associated with adverse effects on pediatric health, including preterm birth, intrauterine growth retardation, perinatal mortality, respiratory illness, neurobehavioral problems, and decreased performance in school. A valid estimation of the risks associated with tobacco exposure depends on accurate measurement. Nicotine and its major metabolite, cotinine, are commonly used as smoking biomarkers, and their levels can be determined in various biological specimens such as blood, saliva, and urine. Recently, hair analysis was found to be a convenient, noninvasive technique for detecting the presence of nicotine exposure. Because nicotine/cotinine accumulates in hair during hair growth, it is a unique measure of longterm, cumulative exposure to tobacco smoke. Although smoking ban policies result in considerable reductions in ETS exposure, children are still exposed significantly to tobacco smoke not only in their homes but also in schools, restaurants, child-care settings, cars, buses, and other public places. Therefore, more effective strategies and public policies to protect preschool children from ETS should be consolidated.
