The purpose of this study was to analyze the influence of a married adult on child-toparent and on parent-to-child financial supports. The data, derived from Korean General Social Survey(KGSS) was obtained from the Survey Research Center at Sung Kyun Kwan University. The samples included 367 married adult children who had more than one living parent. Multiple regression analysis was used to analyze the research model. The findings from the analysis showed that monthly household income had no significant impact on the financial supports that adult children provided to their parents or that the parents provided to their child. The expectation of financial supports from their parents in the future was a important factor that affected the level of female and male children's financial supports that they received from their parents. The level of instrumental supports from their parents and their parents-in-law did influence the level of financial transfers between them. These results showed that financial transfers between married adult children and their parents differed based on the children's attitude towards the supporting parents, and whether or not the children or parents had alternative resources available to them for financial supports. Moreover, the variation in financial supports and benefits showed complex differences based on the gender of the children, and based on whether the financial support was coming from the respondent's parents or their partner's parents.

The purpose of this study is to identify the characteristics and influencing factors of the attachment-oriented caretaking behaviors among the mothers with infants. The total number of 204 mothers participated in this survey as subjects. They all were breast-feeding mothers who had their infants joining in the semi-final round of a healthy breast-feeding infant contest. The data were collected from July 14, 1999 to May 19, 2000. And the data were analyzed by SPSSWIN 10.0 version. The result of this study was as follows ; 1. The mean ages of the subjects were 29.5 and 95.6 percents of them were no-job housewives. 57.8% of them were normal delivery. And the mean months of the infants were 6.2 and the male infants were 57.4%. The first born babies were 62.3%. 2. The mothers are affirmative enough with their attachment-oriented caretaking behaviors (the total mean was $3.58{\pm}.631$). In general, the mothers showed very attachment-oriented caretaking behaviors, but the points that indicated "recording the development characteristics of the infant and discussing them with husband" were very low(score $2.79{\pm}.982$). 3. There are Significant differences in caretaking behaviors of the mothers according to their ages(F=3.497, p=.017), the degree of morning sickness(F=2.633, p=.050) and the birth order of their infants(F=4.854, p=.003). The older mothers and mothers who experienced the less morning sickness showed the higher scores of the attachment-oriented behaviors. The mothers who experienced the more deliveries showed the higher scores of the attachment-oriented behaviors. Accordingly, the above result suggests that the systematic and practical nursing intervention to encourage the attachment-oriented behaviors is essential to the younger, primipara mother.

'청나래'는 국립수목원(Korea National Arboretum)에서 2019년에 육성한 품종이다. 제주도에서 채집한 좀비비추(H. minor)를 모본으로, 외국에서 육성된 H. 'Krossa Regal'을 부본으로 인공 교배하여 종자를 채종하였다. 파종 후 얻은 개체 중 잎의 모양, 색깔 등의 형태적 특성에 차이를 보이는 계통을 우선 선발하였다. 이 중, 잎이 강건하고 화색이 연한 개체를 선발하여 영양번식과 재배를 반복하며 특성 고정 및 검정을 실시하였다. '청나래'는 대조품종인 H.'Black Hills'과 비교하여 잎이 두텁고 색이 진하며(RHS 137A) 잎자루(petiole)와 잎몸(leaf blade)이 만나는 부위에 날개가 있다. 잎몸 가장자리는 물결 모양이 뚜렷하고 화색은 흰색(White N155B)에 가깝다. 이와 같이 육성된 청나래는 분화 또는 정원용으로 활용이 가능하다.
