In the internet broadcast, efficient and scalable mechanism of multicast is needed for the communication between groups. Furthermore, Optimization of the multicast tree is required to improve the performance of overlay multicast. This optimization is well-known as NP-complete. If a node in the tree has limited out-degree, a user who wants to join the group has to find parent user who has already joined. In this paper, the users who want to join the group need to setup their level using delay test from source node. And then new users can find candidate parent nodes effectively using ACK-SEND approach and take proper position by comparing level. The closer node of the user to root node should be located in lower level. Also, even if a barrier is caused, fast recovery will be guaranteed using ACK-SEND approach. Through this, the newcomer node can fine their location in the multicast tree and join the group fast and effectively.

The purpose of this paper is to classify OECD countries in regard to levels of supporting fathers' care work. Several meaningful conclusions were reached. First, examining the level of supporting fathers' care work and the strength of the traditional bread-winner model, OECD countries can be classified into 5 different clusters. The result is different from the mainstream typology of welfare states and suggests the new typology of welfare states. Second, the level of supporting fathers' care work and the strength of the traditional bread-winner model were found to be related to total fertility rates and women's labor market participation rates. Third, in regard to the level of supporting fathers' care work, Korea was the lowest among OECD countries. This result points to one of the important reasons to the low level of total fertility rat, and low rate of women's labor market participation in Korea.

Purpose: The purpose of this study was to investigate pediatric nurse parent partnership and factors associated with this partnership. Methods: A survey was conducted with 158 nurses working in pediatric practice at one of 7 hospitals in Seoul, Incheon, and Chungcheongbuk Province. Data were collected from September to December 2013, and analyzed with SPSS Windows 21.0. Results: In hierarchial multiple regression analysis, self-efficacy (${\beta}$=.19, p=.016), clinical decision making (${\beta}$=.15, p=.046), and empowerment (${\beta}$=.29, p=.001) were associated with pediatric nurse parent partnership, after adjusting for marital status, children, education, position and satisfaction with work unit. These factors accounted for 44.0% of the variance in the pediatric nurse parent relationship. Conclusion: These results suggest that pediatric nurse parent partnership could be influenced by the predictors. Ultimately, intervention programs focusing on these factors should be effective in helping pediatric nurses improve partnership with parents.

Data were gathered from the Statistics Korea Life Time Surveys from 2004(y1) and 2019(y2) (n=2,697). Life time was composed of three types(inevitable time, compulsory time, and leisure time) and leisure time was categorized into 11 activities(voluntarism, participation, social relationships, religion, rituals, culture and tourism, sports, game and play, media, rest, and others) to investigate gender differences and time effects. The major results were as follows: First, both working fathers and mothers with preschool children spent less inevitable time, more compulsory time, and less leisure time, than other adult group. Second, fathers spent more time on 10 leisure activities except religion in y1, and on all activities than mothers in y2. In y2, less time on three activities(social relationships, rituals, and media) for both fathers and mothers, less time on religion for mothers only, more time on two activities(participation, game and play) for both groups were spent than y1. Third, in the regression analysis of fathers' and mothers' leisure time on three leisure activities(sports, game and play, and media) with a distinct pattern from leisure time for adult group between y1 and y2, socioeconomic variables and lifetime variables showed different effects by gender and waves.

Purpose: To investigate the genetic association of visual acuity(VA) between young children, schoolchildren, juveniles, and their parents. Methods: 208(4 to 18 yrs) subjects who are belongs to young children, schoolchildren and juveniles and 340 their parents were assessed. Corrected and uncorrected visual acuity in each eye were measured using Han's test chart(5m). Results: There was no correlation with father's VA on under 6years but mother's VA tend to effect on male children. In case of elementary school students, their VA shows strong correlations with their parents VA; VA uner 0.7 group shows both parents VA was under 0.7 and VA over 0.7 group tend to shows their parents VA was over 0.7. Moreover, in juvenile, there was strong correlation between mother's VA and male children's VA. Conclusion: Our study showed that the family history, especially mother's visual acuity, had more effect on the problem of their children's visual acuity.
