Korea, which became an aging society in 2000, has made transition to an aged society more quickly than expected since late 2017 after 17 years. Despite this trend, the awareness towards elderly housing facilities has not yet been raised across in society. The primary reason is that use of elderly housing facilities has not been promoted due to lack of understanding about the construction and management of the facilities. The housing of the elderly should be considered in terms of not only residential space but also the issues of medical care and continuous care. Therefore, the trend of elderly housing is pursuing the Continuing Care Retirement Community. Thus, this study analyzed the policies of existing elderly housing facilities and existing elderly housing through comparison with policies and housing of foreign countries. Based on the results, the the government intends to present characteristics and direction of suitable housing design of senior citizens' housing facilities through maintenance of UNIT, securing convergence through changes in the use of facilities, and realising the cost of operation, and studying social welfare measures to cope with the increasing number of elderly residents.

Due to the recent surge in popularity of cryptocurrency, the threat of cryptojacking, a malicious code for mining cryptocurrencies, is increasing. In particular, web-based cryptojacking is easy to attack because the victim can mine cryptocurrencies using the victim's PC resources just by accessing the website and simply adding mining scripts. The cryptojacking attack causes poor performance and malfunction. It can also cause hardware failure due to overheating and aging caused by mining. Cryptojacking is difficult for victims to recognize the damage, so research is needed to efficiently detect and block cryptojacking. In this work, we take representative distinct symptoms of cryptojacking as an indicator and propose a new architecture. We utilized the K-Nearst Neighbors(KNN) model, which trained computer performance indicators as behavior-based dynamic analysis techniques. In addition, a K-means model, which trained the frequency of malicious script words for script similarity-based static analysis techniques, was utilized. The KNN model had 99.6% accuracy, and the K-means model had a silhouette coefficient of 0.61 for normal clusters.

The purpose of this study is to investigate the effect of grandparenting on the grandparent's level of depression. In addition, it is to test the mediating effect of social support and the moderating effect of household type on the relationships between variables. The 555 grandparent sample in this study was from the Korean Longitudinal Study of Aging(KLoSA). The findings indicated that grandparenting(grandparenting time per day and total weeks of grandparenting per year) was significantly related to the grandparent's level of depression. In addition, the grandparent's age was also associated with grandparenting, grandparent's depression, and social support. Grandparent's health condition and marital status was associated with social support. Grandparent's gender had a significant relationship with grandparent's depression and grandparenting time per day. Social support had a direct effect to the grandparent's depression; however, it was not a statistically significant mediator between grandparenting and grandparent's depression. In addition, household type was not a significant moderator of measuring the relationships among grandparenting, grandparent's depression, and social support. Implications for social work practice were discussed based on the result of the study.

Korea is expected to become an "aged society" in approximately fifteen years. In order to prepare Korean society for this "aged society", the government and social organizaitons need to offer a life stage preparation manual for the young, middle-aged, and aging populations, as well as providing support structures to guide them through this transition. Researchers have developed a Life Stage Preparation Program, based on surveys and experiments conducted to assess needs and appraise effectiveness. To accomplish the goal of this research, the team has been composed of specialists from the fields of social welfare, family studies, occupational studies, and gerontology. The Life Stage Preparation Program consists of ten areas: understanding ageing issues, sustaining and improving health, psychological issues, continuing education, family relations, social activities, financial preparation, occupations, shelter, and mortality. The effectiveness of the program surveyed on age group of 20s and 60s resulted in nine areas. The Life Stage Preparation Program needs to be operated as a life long education program.

This study aimed to address the effect of poverty on depression and self-rated health in older adults living alone in Korea. In addition, this study identified the mediating effect of social participation on the poverty-depression and poverty-self-rated health relationships. The researcher conducted a secondary data analysis using the 6th wave of the Korean Longitudinal Study on Aging. The final sample was 1,093 older adults living alone. Using structural equation modeling, standardized coefficients of each path were analyzed. Then, the statistical significance of the mediating effect of social participation was addressed via analyzing direct, indirect, and total effects. Results show that older adults under poverty were more depressed and had a lower level of self-rated health than their counterparts. Moreover, frequent participation in religious gatherings, social gatherings, and leisure activities decreased depression in older adults living alone. Moreover, religious gatherings, social gatherings, and alumni meetings were positively related to self-rated health om older adults living alone. Significant mediating effects appeared in poverty-social gathering-depression, poverty-social gathering-self-rated health, and poverty-alumni meeting-self-rated health relationships. Based on the results, the researcher also discussed implications for social work practice.

Smartphone use has become a part of everyday life, not only for adolescents but also for elderly and older people. Thus, this study explored the effect of demographic variables, the amount of smartphone usage, type of smartphone use and psychosocial variables on smartphone dependence of the elder group. We analyzed the data of 5627 (50s and 60s) of the Internet overdependence survey data of the Korea Information Society Agency in 2016. As a result of hierarchical multiple regression analysis, More frequency of smartphone use of weekday and weekend, and usage time of smartphone of weekday were related to greater smartphone dependence. More smartphone use for information seeking and games were associated with greater smartphone dependence. And, as loneliness and anxiety increased, smartphone dependence increased, while smartphone dependence decreased, as social capital increased. Through this study, it is necessary to understand characteristics related to smartphone dependence of elder and older group, and to use this knowledge to solve their smartphone dependence. Future studies also need to identify the causal relationship between predictors of smartphone dependence in elderly and older people.
