According to IT development, smart home services is providing remote service, monitoring service and other various services through smart home devices based on network. But, smart home environment exists security threats such as data falsification, illegal authentication and invasion of privacy through a malicious device. Smart home is studying to prevent these security threats, but the studies of smart home environment security are still in early stage of development and the studies of group key management method is lacking in smart home. In this paper, we propose the group key management method for secure device in smart home.

The purpose of the research was to determine the effect of home care service on the quality of life in patients with gynecological cancer. This randomized case control study was carried out in a womans hospital between September 2011 and February 2012. Women undergoing gynecological cancer treatment were separated into intervention and control groups, of 35 patients each. The intervention group was provided with nursing care service through hospital and home visits ($1^{st}$, $12^{th}$ weeks) within the framework of a specifically developed nursing care plan. The control group was monitored without any intervention through the hospital routine protocols ($1^{st}$, $12^{th}$ weeks). Data were collected using An Interview Form, Home Visit Monitoring Form and Quality of Life Scale/Cancer Survivors. Effects of home care service on the quality of life in gynecological cancer patients were investigated using chi-square tests, McNemar's test, independent t-test and ANOVA. This study found that the intervention group receiving home care service had a moderately high quality of life (average mean: $6.01{\pm}0.64$), while the control group had comparatively lower quality (average mean: $4.35{\pm}0.79$) within the 12 week post-discharge period (p<0.05). This study found home care services to be efficient in improving the quality of life in patients with gynecological cancer.

Purpose: This study was conducted to evaluate the effect of a social support program on family caregivers' role strain in elderly long-term home care. Methods: The research adopted a non-equivalent control group pretest-posttest design. The number of participants was 25 in the experimental group and 25 in the control group sampled among family caregivers in elderly long-term home care. The experimental group participated in a 10-session social support program, which consisted of physical, emotional, informational, and material support. The effect of the program was evaluated by measuring family caregivers' role strain. Results: The experimental group showed a significant decrease in family caregivers' role strain in elderly long-term home care. Conclusion: The result suggests that the social support program was effective in decreasing family caregivers' role strain in elderly long-term home care. There is a need to develop more effective and systematicsocial support programsfor family caregivers of elderly long-term home care.

Purpose: A quasi-experimental study was performed to investigate the effects of a home visiting discharge education program on the maternal self-esteem, attachment, postpartum depression and family function in 35 mothers of neonatal intensive care unit (NICU) infants. Methods: Twenty-three mothers in the intervention group received the home visiting discharge education while 12 mothers in the control group received the routine, hospital discharge education. Baseline data was collected in both groups one day after delivery. The intervention group received the home visiting discharge education while the control group did the routine hospital-based discharge education. The questionnaire including the data on maternal self-esteem, attachment, postpartum depression and family function were collected within 1 week after the discharge by mail. Results: The scores of maternal self-esteem, and attachment were significantly increased, and the postpartum depression and the family function score were decreased after the home visiting discharge education in intervention group. There were no changes in these variables before and after the routine hospital-based discharge education in control group. Conclusion: These results support the beneficial effects of home visiting discharge education on the maternal role adaptation and family function of the mothers of NICU infants.

Purpose: We compared cost-effectiveness parameters between inpatient and home-based hospice-palliative care services for terminal cancer patients in Korea. Methods: A decision-analytic Markov model was used to compare the cost-effectiveness of hospice-palliative care in an inpatient unit (inpatient-start group) and at home (home-start group). The model adopted a healthcare system perspective, with a 9-week horizon and a 1-week cycle length. The transition probabilities were calculated based on the reports from the Korean National Cancer Center in 2017 and Health Insurance Review & Assessment Service in 2020. Quality of life (QOL) was converted to the quality-adjusted life week (QALW). Modeling and cost-effectiveness analysis were performed with TreeAge software. The weekly medical cost was estimated to be 2,481,479 Korean won (KRW) for inpatient hospice-palliative care and 225,688 KRW for home-based hospice-palliative care. One-way sensitivity analysis was used to assess the impact of different scenarios and assumptions on the model results. Results: Compared with the inpatient-start group, the incremental cost of the home-start group was 697,657 KRW, and the incremental effectiveness based on QOL was 0.88 QALW. The incremental cost-effectiveness ratio (ICER) of the home-start group was 796,476 KRW/QALW. Based on one-way sensitivity analyses, the ICER was predicted to increase to 1,626,988 KRW/QALW if the weekly cost of home-based hospice doubled, but it was estimated to decrease to -2,898,361 KRW/QALW if death rates at home doubled. Conclusion: Home-based hospice-palliative care may be more cost-effective than inpatient hospice-palliative care. Home-based hospice appears to be affordable even if the associated medical expenditures double.

To investigate the actual conditions on the living environment of group-homes for the elderly and their living environment, 4 group-homes were surveyed. As the results, conditions of location for the group-home of the elderly looked positive, on the other hand, safety for criminal prevention, accessability and convenient facilities were not on level satisfied. The average area of each space in the group-home indicated that the bed room was $11.21\;m^2$, the living room $28.13\;m^2$, the kitchen $23.59\;m^2$, and the bath room had an integrated type of bath room and toilet $7.63\;m^2$. The physical environments of each space in the group-home were investigated, In bed room, door, windows and illumination were relatively good but safety was extremely inferior. Living room mostly looked good except the doorsill which needs refurbishment. In kitchen, cooking table, windows, illumination, ventilator were somewhat satisfactory but gas-warning device should have been installed. In addition, in bath room and toilet, location, door, window, illumination and finished material were satisfactory. But the stepped difference between the bath room and other space, safety-bar, emergency bell and floor heating system were seriously deteriorated and must be improved for the safety of the elderly. Conclusively, living environment of group-home for the elderly is mainly satisfactory but it was necessary to take a consideration for their safety.
