Purpose: We conducted a descriptive study to: 1) understand how husbands are aware of the importance of Sanhujoiri(i.e, Korean traditional postpartum care) and 2) identify their needs to learn how to take care of postpartum women and newborns and to strengthen family bonding. Methods: The subjects consisted of 123 husbands who had children under the age of 5 years. Data were analyzed with t-test, one-way ANOVA, $Scheff{\acute{e}}^{\prime}s$ test, and Pearson's correlation. Results: The mean age of subjects was $37.1{\pm}4.63$ years. The mean scores of awareness, needs for education on postpartum mother and newborn care, and family strength were $4.57{\pm}1.18$, $4.61{\pm}1.18$, $4.92{\pm}1.07$, and $4.01{\pm}0.95$, respectively, indicating higher scores. There were statistically significant differences in awareness (F=5.08, p<.05), newborn care (F=3.70, p<.05), and family strength (F=4.64, p<.05) by husband's role in Sanhujori There was a positive correlation among study variables. Conclusion: This study shows that even though husbands want to participate in Sanhujori, they do not have enough information on Sanhujori and mother/newborn care and adequate paternity leave. Realistic paternity leave system and effective Couple Centered Childbearing (from pregnancy to postpartum) Education Program CCCEP development are required to help husbands' participation in mother/newborn care with confidence and competence in home based Sanhujori.

The aim of this study was to evaluate the genetic parameters of growth traits for improvement breeding in olive flounder Paralichthys olivaceus at the 8^th generation of selective breeding in April 2021. Growth traits such as total length, body weight and condition factor at 11 months of age were measured for 7,508 individuals with confirmed paternity. Data were analyzed using the restricted maximum likelihood method applied to a multiple traits animal model. The effects of sex and family were significantly different across traits (P<0.05). The heritability values of total length, body weight and condition factor were estimated to be high as 0.479, 0.457, and 0.466, respectively. Correlation analysis between phenotypic and breeding values, indicated that the selection accuracy was 75.9-85.2% for all traits. To increase the selection accuracy for parent fish selection, the sex and pedigree characteristics that affect each trait should be considered. Moreover, further improvement of multiple traits can be achieved if the correlation between each trait is appropriately considered.

부안지역 소나무 집단의 화분유동과 교배양식 모수를 추정하기 위하여 7개 microsatellite 표지로 모수, 주변 성목 및 종자에 대한 유전변이를 분석하였다. 이형접합도 기대치($H_e$)와 근교계수(F)는 각각 모수에서 0.614과 0.018, 종자에서 0.624과 0.087이며, 각 세대간에 차이는 없었다(P > 0.05). MLTR로 추정한 타가교배율($t_m$)은 0.967이며, 양친간 근연계수($t_m-t_s$)는 0.057, 부계상관($r_p$)은 0.012로 나타났다. 기존에 보고된 소나무의 동위효소 분석 결과에 비하여 타가교배율은 높고 근친교배 및 부계상관은 낮았으나, microsatellite 표지를 이용한 소나무류의 결과들과는 유사하였다. TwoGener로 추정한 최적 화분비산 모델은 유효밀도(d = 220 trees/ha)를 가정한 정규확산모델로 판명되었으며, 평균 화분비산거리(${\delta}$)는 11.42 m로 계산되었다. 화분원 유전적 분화(${\Phi}_{ft}$)는 0.021이며, Mental 검증에서 모수간 지리적 거리와 화분원의 유전적 분화는 상관성이 없는 것으로 나타났다(r = -0.141, P > 0.05). 부안지역 소나무 집단은 대부분의 화분이 가까운 거리에서 공급되지만, 화분수의 유전다양성이 높고 화분원의 유전적 차이가 작은 상태로 추정된다. 이러한 조건에서 완전한 임의교배가 이루어지기 때문에 종자의 유전자형이 다양하며 세대간 유전변이의 감소가 없는 것으로 사료된다.
