The home network has been revitalized due to the emergence of the high-speed broadband network and explosive increases of the home network services. Especially multicast based high-definition (HD) IPTV service is on high demand from both Internet service provider (ISP) and users. In order to provide high quality HD IPTV service without packet loss and delay, the ISP utilizes various network QoS mechanisms. Due to the misleading fact, that the home gateway is considered as an end terminal in terms of the ISP's viewpoint, the ISPs can not guarantee the end-to-end QoS within the scope of the current home network architecture. Therefore, an independent QoS guaranteed mechanism should be considered within the home network domain. As the home gateway manages both private home and public access network within the home network, we propose and implement a novel QoS mechanism for the multicast based HD IPTV service over the home gateway. In order to provide QoS guaranteed HD IPTV service, the proposed mechanism classifies the packets, manages home network bandwidth resources, and executes call admission control using the channel join message. Also, we utilize layer 2 multicast packet forwarding scheme to improve the overall performance of the home network services. Through the experiments of implementing the multicast based HD IPTV services, we will verify the efficiency of the proposed mechanism.
Presented here are policy alternatives for understanding home health care for the long-term health care insurance system which is being developed for elderly people starting 2007. The summary of issues concerning home health nursing care under the long-term care insurance system include; 1) absence of comprehensive and systematic policy in home health care deliverly systems; 2) absence of community based home health agencies that are considered as the community residents in general. In order to overcome these problems and Issues, policy alternatives of home health care should 1) establish a comprehensive home health care policy for homebound persons; 2) establish the foundations for home health care nurses and community based home health care systems; 3) establish home health care facilities and infrastructure; and 4) promote research and development concerning home health care. Conclusively, a home health care system should be built on a comprehensive policy vision based on health policy, especially long-term care insurance system in the near future. Every homebound residents service has to be constructed systematically under suitable facilities considering the consumer characteristics and health conditions. By doing this, the consumer based comprehensive community home health care delivery system can be constructed in view of the long-term health care insurance system for elderly people.
This study examined in depth what teachers experience in a practical problem-based home economics class. This study established the research question, "What do teachers experience in the practical problem-based home economics class?" and selected three teacher participants who had steadily performed a practical problem-based home economics class to directly observe classes and conducted intensive interviews with the class performing teachers. The three research participants performed the practical problem-based class as a method of practicing their educational beliefs and based on a problem consciousness that textbook centered classes focusing on concepts cannot manage. They also tried to make efforts to reconstruct the textbook centered with practical problems to promote the critical thinking abilities of students. In practicing the practical problem-based class, the research participants recognized that it was important to show the present problems in reality to the students, teach broad value concepts, and establish rapport with students. They tried to make class content correspond to class evaluation. They felt awarded in how they influenced the development of students and the perception of home economics subjects in a positive way as well as experienced various actual difficulties in performing the practical problem-based class. The three research participants examined themselves through the agony and reflection of the class, and integrated the class with daily activities by applying problem solving methods of practical problem-based classes to their lives.

The purpose of this study was to estimate home care nursing cost for the patient with Cerebrovascular Disease based on a bundle of home care nursing services This study was conducted through four steps. The first step was to investigate home care nursing activities that were offered to the patient with Cerebrovascular Disease(CD) by home care nurse. The second step was to investigate the time spent on home care nursing service and to calculate labor and manufacturing cost. The third step was to calculate home care nursing cost per minute. And at the fourth step, home care nursing cost for a patient with Cerebrovascular Disease based on a bundle of home care nursing service was calculated. The results of the study were as follows: 1) The number of direct home care nursing activities for the patient with CD was 108, and the time of each activity was spent from 1 to 10 minutes. 2) Average time per visit was 51 minute, and the firs visit time were spent 1.6 times higher than 2nd visit time. 3) Nursing cost per minute(cost per visit ${\\}\;22,565\;\div\;$ average time per visit 51 minutes) was ${\\}\;442$. The cost per visit was calculated on Basic visiting cost(nurse's labor cost ${\\}\;15,760$ + management cost ${\\}\;6,805$) divided by average time per visit(51 minutes). 4) Home care nursing cost to the patient with CD based on bundle of home care nursing service was consisted of basic home care nursing cost, the cost of a bundle of service practiced on visit. and transportation fee. Basic home nursing cost(the time spent on basic home nursing service 20 minutes ${\times}$ nursing cost per minute ${\\}\;442$) was ${\\}\;8,840$. The cost of the bundle of home care nursing services to the patient with CD was calculated as self care ${\\}\;2.898$, Tracheostomy care ${\\}\;10,166$, immobility care ${\\}\;6,188$, sore care ${\\}\;6,188$. Foley care ${\\}\;6,630$, and Levin tube or Gastrostomy care ${\\}\;7.514$. Transportation fee which was composed of the labor cost for transportation(${\\}\;5,122$) and the car management cost(${\\}\;3.876$) was ${\\}\;8,998$. Home care nursing cost to the patient with CD based on bundle of home care nursing services consisted of basic home care nursing cost, the cost of a bundle of service practiced on visit, and transportation fee. It will contribute to improve quality of home care service, because of giving appreciate incentives to home care nurses. And it will be more efficient than current cost of hospital based home care. But it need to management than calculation of the current fee-for-services of home care.

Recently, LEE et al. proposed an attribute-based authenticated key agreement protocol over home network, which aimed to support authentication and key agreement between user and home server. However, if the home server is attacked in the protocol, the effects are influenced to the overall home network components severly. Thereby, this paper proposes a new ticket-based authentication protocol using user attributes between user and home devices to solve the problem. The proposed protocol supports the various levels of security to user by diversifying the network accessibility depending on user attribute. Thereby, the protocol could support more secure home network services.
The purpose of this study was to examine the determinants of economic contributions of home-based family businesses. The results suggested that positive effect on direct contributions of home-based family businesses was associated with a male manager, more family members, more employees, non-family employees in the business, engaged in food and restaurant business, located in Seoul area, and higher perceived success of the business. Positive effect on indirect contributions of home-based family businesses was associated with a female manager, a child under age 6, only family members as employees, and greater initial investment in the business. Working hours were negatively related to the indirect contributions. Greater total economic contributions of the home-based family businesses was associated with a male manager, more family members, more employees, non-family employees in the business, engaged in restaurant business, located in Seoul, and higher perceived success on the business.

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.

Home health care system in Korea has been classified into three types of home care programs based on different laws and regulations; for example, home health care nursing(HHCN) is based on medical laws, visiting health care nursing (VHCN) is based on long-term health care insurance, and visiting health care(VHC) is based on the regional health care act. HHCN in Korea has taken on an important role under the mandate of the national health care system since 2000. VHCN will commence its role under the long term health care insurance system in 2008. The strengthening of VHC commanded health promotion and prevention for vulnerable families in the community in 2007. This is an important turning point for increasing quality management for home health care program; it suggests certain possibilities for building a foundation for further changes in the service delivery structure. Accordingly, the home health care policy makers in Korea have a major function and role that consists of developing an agenda and alternatives for policy making in a systematic manner and clearly presenting implementation strategies for elderly health care system.
Purpose: The purpose of this study was to analyze the differences in terms of services and cost between CVA without typical diseases (Group I), and CVA with typical diseases (Group II), in their Hospital-based home health care. Method: The subjects of this study were 308 CVA patients who used home care nursing during the second phase demonstration project of their hospital-based home health care. Results: The results of the study was as follows 1. Group II had more home visit (15.3/12.7) (p>0.05), and cases of death when home care (16.8/11.4) (p<0.05). 2. Group II needed more services than Group I such as bladder irrigation, skin care, bed sore care, glycerin enema, finger enema, lung care, urine sugar test, monitoring and surveillance of fluid infusion and R.O.M exercise (p<0.05). 3. The variables that showed statistical significance in the regression analysis were family style, OPD visit, level of consciousness, patient's state on termination of home care, and some extend of home health care services (R2=0.373, 0.205). Conclusion: Home nursing care needs to be planned by severity in Hospital-based home health care for CVA patients.
