행복한 가정의 비결 가운데 첫번째로 꼽힌것도 가족간의 대화이다. 가정의 모든 행복은 바로 '말'에서 시작하고 끝난다고 해도 과언이 아니다. 자녀에게 말한마디가 얼마나 큰 영향을 미치는지 자녀의 입장에서 생각해보는 것이 필요하다.

The purpose of this study was to develop the couple breast-feeding education program and to investigate the effects of program on breast-feeding self-efficacy, spouse support and breast-feeding satisfaction of primipara. The 3 session(20-40 min/one day) the breastfeeding spouses education program was developed and a non-equivalent control group quasi-experiment design was used. Sixty-three participants were assigned to either the experimental group (n=32) or the control group (n=31). A pre-test and post-test were done to identify the effect of the program. Effects were tested using $x^2$-test, t-test. Scores for breast-feeding self-efficacy(t=3.44, p=.001), spouse support(t=3.03, p=.004) and breast-feeding satisfaction(t=3.64, p=.001) of the experimental group after program were significantly higher than the control group scores. The effects of the couple breast-feeding education program for elevating breast-feeding self-efficacy, spouse support and breast-feeding satisfaction of primipara were validated. Therefore, this program can be recommended for vigorous use in clinical practice.

This research aims to categorize factors affecting reluctance of second childbirth among working mothers using Q methodology. P sample holds 50 working mothers between 20 and 45 years old living in Daegu-Gyeongbuk area. After securing the total 72 statements, the final 24 Q samples were confirmed through the second classification. As a result of this study, three types of the working mothers were classified. The first type that 22 working mothers (44%) were classified was "having uncooperative spouse". The second type which 13 working mothers (26%) were included was "working at not family-friendly workplace". Lastly, eight working mothers (16%) belonged to the third type, "having financial difficulty". Therefore, this study could confirm that the working mothers evade their second childbirth mostly because of the insufficient childcare support both at home and at work, rather than economic reasons. Thus, this study suggests that the Korean government should try to spread work-family balance culture than just providing financial support in order to encourage the second childbirth among working mothers.

This study was conducted to investigate the effects of dietary germanium biotite supplementation on egg quality and fecal noxious gas content in laying hens. One hundred and forty-four 40-wk-old, ISA Brown layers were used in this experiment. Dietary treatments were 1) CON(control diet), 2) GB0.5(control diet + 0.5% germanium biotite), 3) GB1.0 (control diet + 1.0% germanium biotite) and 4) GB1.5(control diet + 1.5% germanium biotite). Hen-day egg Production and egg shell breaking strength were not influenced by germanium biotite supplementation. However, egg weight decrease as the level of germanium biotite supplementation increased in the diets increased(Cubic effect, p<0.02). Eggshell thickness, yolk color and yolk index were not influenced by garmanium biotite supplementation. Serum triglyceride concentration as dietary germanium biotite increased (linear effect P<0.02; quadratic effect, p<0.05). Dietary supplementation of germanium biotite reduced fecal NH$_3$-N concentration (P<0.01), propionic acid(P<0.01), butyric acid( P<0.05) and acetic aicd(P<0.01) concentrations in the feces. In conclusion, the results of this experiment indicated that dietary germanium biotite supplementation did not affect egg shell quality, but reduced fecal NH$_3$-N concentration.

Weathering profiles which were developed under a temperate, humid environment and relatively steep geography, show a thick saprolite and soil horiaon in the Precambrian granitic gneiss of the Yoogoo area. In the weathering profiles, secondary minerals such as interstratified biotite/vermiculite, tri- or di-octahedral vermiculite, halloysite, kaolinite, illite, smectite, gibsite and geothite were observed. Kaolinization of biotite is the most prevalent mechanism but vermiculitization is a minor from all ofweathering profiles. Biotite altered to B/V mixed layer-vermiculite, to illite and to halloysite, kaolinite and gibbsite. Halloysite is the most frequently observed weathering product of biotite in these profiles. Goethite is observed at the around or opened fissures of altered biotite. Tubular halloysite aggregates was fDrmed from dissolution-precipitation of plagioclase. The occurrence of halloysite aggregates is divided into a preferentially oriented type and a wrinkled one which were resulted from the dissolved type of plagioclase. Fe-bearing minerals have also been subjected to dissolution leaving the precipitation of geothite along dissolution voids. The profile of granitic gneiss is a typical weathering pattern showing a clay minerals increase toward the surface. Weathering of minerals were controlled by locally acidic and good-drainage environment, and formed a various and complicated secondary minerals in this study area.

Nuclear factor I (NFI) exists in the odontoblast and osteoblast. NFI-C null mice demonstrated aberrant odontoblast differentiation, abnormal dentin formation, and molar lacking roots. The purpose of this study was to examine phenotype of the aberrant odontoblast in NFI-C null mice and to evaluate the expression of DSPP and BSP mRNAs in NFI-C null mice with in-situ hybridization. The results were as follows: 1. In the NFI-C (-/-) mice, the crown dentin of molar showed normally formation, but there was no root dentin. 2. In the NFI-C (-/-) mice, the labial dentin of mandibular incisors showed relatively a lot of dentin formation, but the lingual dentin showed defect. 3. In the NFI-C (-/-) mice, the odontoblast of mandibular incisors revealed abnormal shape and trapped in osteodentin-like mineralized tissue. 4. In the NFI-C (-/-) mice, the odontoblast in the crown dentin of molars showed strong expression of DSPP, the odontoblast in the root dentin of molars was not expression of DSPP. In the NFI-C (-/-) mice the odontoblast in the mandibular incisors showed weekly expression of DSPP 5. In the wild mice, the odontoblasts of mandibular incisors were not expression of BSP, but in the NFI-C (-/ -) mice the odontoblast of mandibular incisors showed strong expression of BSP These results suggest that odontoblast in the NFI-C (-/-) mice changes the phenotype into osteoblast.

With a substantial rise in divorce rates since the mid 1990s, single-parent households are increasing rapidly in Korea. Often it is believed that children in single-mother households suffer the most economically and socially with the marital disruption of the parents. This study hypothesizes that in Korea the socioeconomic status of single-father households may be lower than that of single-mother households mainly because low-income divorced women are not able to form their own households with children. The analysis is based on two sub-samples from the 2% sample of the 2005 Census, one, with children 12 years old or younger and, the other, with divorced mothers of children of the same ages. The findings support the hypothesis that previously-married single fathers show the lowest educational and occupational status among 6 groups of parents: fathers and mothers from two-parent families, fathers and mothers from married but spouse-absent families, and previously-married single fathers and mothers. Divorced mothers'likelihood of living apart from their children has a strong negative association with their educational attainment, with the highest likelihood among women of middle school or lower education and the lowest likelihood among women with college education. Although single mothers comprise a larger percentage of single-parent households, single-father households demonstrate a particular vulnerability with their weak socioeconomic status.

목적 : 프리모 모드와 미성숙 간조직에 대한 조직학적 특성을 비교하고자 하였다. 방법 : 흰쥐에서 간절제한 후, 간장기 표면에서 관찰되는 프리모 모드와 그와 유사한 미성숙 간조직을 H&E, Oil red O, Masson trichrome and van Gieson 염색방법을 통해서 비교 연구하였다. 결과 : 상기 실험 연구를 진행한 결과, 다음과 같은 결론을 얻었다. 1. 조직의 일반적인 특징을 관찰할 수 있는 H&E 염색결과, 프리모 노드에서는 많은 수의 조그마한 동(sinus)이 관찰되었고 적혈구나 영양을 공급하는 혈관의 분포는 관찰되지 않았다. 이와 반대로 미성숙 간조직에서는 동이 관찰되지 않았으며 혈관의 분포와 적혈구가 관찰되었다. 2. 양 조직의 지방성분의 유무를 관찰하기 위한 Oil red O 염색결과, 프리모 노드에서는 지방성분이 관찰되지 않았으나 미성숙 간조직에서는 관찰되었다. 3. 양 조직의 콜라겐성분의 유무를 관찰하기 위한 Masson trichrome and van Gieson 염색결과, 프리모 노드에서는 약간의 콜라겐 성분이 관찰되었으나 elastic 성분은 관찰되지 않았으며, 미성숙 간조직에서는 콜라겐 성분과 elastic 성분이 관찰되지 않았다. 결론 : 상기 결과는 프리모 노드와 간조직과는 조직학적 성질이 다른 것으로 사료되며, 특히 콜라겐 성분의 적은 결과는 프리모 노드가 불규칙한 형태를 이루고 있는 이유에 대한 실마리를 제공하였다. 이러한 결과는 프리모 노드의 특성에 대한 기본 자료로 활용될 수 있을 것이다.
