A new era of research has focused on examining the growth of change in drinking problems among the elderly. Thus, the purpose of the present study was two fold: (1) to investigate trajectories of drinking problems(CAGE) among the Korean elderly(age$${\geq_-}65$$); and (2) to identify the predicting factors for the intercept and the slope of alcohol problems using multi-level growth curve model. Data come from three waves(1st wave(2006)~3rd wave(2008) of the Korea Welfare Panel(KWP) study. The results indicated that the levels of drinking problems decreased over time and that age, gender, marital status, religion, poverty, self-rated health, and social relationship satisfaction were associated with the baseline CAGE. Further analysis showed that social relationship satisfaction affected the declining slope of drinking problems over time. Specifically, among those who satisfied social relationship, there was a sharp decline of CAGE over time. Overall findings highlight the importance of developing and implementing effective alcohol prevention programs for the elderly in the community settings to mitigate the harmful effects of various psycho-social stressors. Especially, programs to maintain and form healthy social support network are suggested as critical interventions for prevention as well as recovery of alcohol problems in late life.

The present study examines the development of self-esteem from young adulthood to old age, as well as predictors of change in self-esteem over time. The eight waves of Korean Welfare Panel Data(KOWEPS) were used for analyses, and a nationally representative sample of 15,511 individual aged 19 years and above were included. The multilevel growth curve model was specified to address the research questions. The result shows that the self-esteem trajectory differed across different age groups with those in early adulthood and adulthood showed an increasing linear trajectories while the old age showed a declining slope. Furthermore, predictors of changes in self-esteem also differed across the age groups that while depression and relationship variables were constant in predicting self-esteem change for all three age groups, some variables such as marital status, poverty status, and employment status predicted individuals in certain age groups. Such results demonstrate the need to understand and examine the change in self-esteem at the individual level.

Important Java network application services have been rapidly increased along with the growth of the Internet. So, it is desirable for such applications to serve transparently, continuously and safely even if the network is temporally partitioned or certain hosts running those services are crashed down. To satisfy such requirements, many group communication systems have been developed. However, existing Java-based group communication systems do not support both the extended virtual synchrony and various types of message delivery such as FIFO, causal, total and safe delivery service. In this paper, we present the design and implementation of a Java group communication system, named JACE, supporting various types of message delivery between group members and the extended virtual synchrony model. The JACE system consists of a number of protocol modules which can be stacked on top of each other in a variety of ways. In addition, using the JACE system, we have developed an experimental UDDI registry for discovering and publishing information about Web services.
