Purpose - Along with the growing awareness of environmental sustainability, international green entrepreneurship is expected to realize international sustainable development (ISD) by introducing ecological innovation results, using fewer resources consumption, and reducing negative environmental impacts. Building upon contingency theory and social network theory, this paper attempts to explore the role of home country-based networks (technology ties and business ties) as contingent factors that might impact the effectiveness of entrepreneurial orientation (EO) in promoting ISD among green ventures. Design/methodology - Original data were collected from 127 green ventures in China based on the random sampling technique. These green ventures mainly focus on the lower use of energy or materials, lower CO2 emissions, and higher ecological benefits located in the Fujian province, which highlights green economic growth and economic cooperation with international markets. Moderated hierarchical linear regression analysis was conducted to test our hypotheses concerning the main relationship between EO (innovativeness, proactiveness, and risk-taking) and ISD as well as the moderating effects of home country-based networks (technology ties and business ties) on the main relationship. Findings - Empirical results indicate that: first, both innovativeness and proactiveness positively affect ISD; second, both technology ties and business ties at home might significantly strengthen the positive relationship between innovativeness (or proactiveness) and ISD. However, this study did not find significant moderating effects of technology ties or business ties at home on the relationship between risk-taking and ISD. Originality/value - Since previous literature often gives more focus on the host country context of social networks, this study shifts to a home country-based network context. Therefore, our research might enrich the international green entrepreneurship literature by empirically investigating the contingent value of home country-based networks in the relationship between EO and ISD in the context of an emerging economy such as China.

Fruition for a diverse uIT(Ubiquitous Information Technology) service is currently required through the convergence of what is known as ubiquitous computing technology. In recent years, with the rapid growth of the need for information services, heavier demands have been made upon the supply of high-quality multimedia services that require a high bandwidth. Today, various home network solutions have been proposed to manage these service smoothly and a system able to deal with various types of network traffic without delays. In addition, in established home network environments that mix wired and wireless networks, along with the steady evolution of wireless network technology and the earnest development of ubiquitous computing technology, sensor-based wireless networks have emerged as a core solution for home networks. In this paper, a sensor network-based home control system supporting the next generation home gateway system for ubiquitous home environments is designed and implemented.

There are three main purposes in this study. First, we project the number of elderly dementia population in the future based on the projection of the elderly population in the Kyungpook area. Second, the demands of home-based care service and facility-based care for the elderly dementia are estimated. Thirdly, some policy implications for the improvement of welfare services for the elderly dementia are addressed. The findings of this study are as follows. Considering the size of the elderly dementia population, facilities for the elderly dementia are extremely insufficient and most of the elderly dementia patients rely heavily on home-based care. Although we expect that there will be a rapid increase in the number of the elderly dementia in the next two decades, the social welfare services for them in the future are very unreliable. Home nursing for the demented elderly needs to be recognized by law and financed by the government. In this context, we address some issues regarding the rapid growth of the elderly dementia population in the future and social welfare services for them as well. Finally we suggest some policy implications regarding this matter.

In this paper, we introduced our designed TDMA (Time Division Multiple Access) based MAC (Medium Access Control) protocol for Home Networks called HomeTDMA. We have implemented and tested it in a test bed using crossbow motes and TinyOS. We also have compared HomeTDMA and CSMA (Carrier Sense Multiple Access) in terms of space and time complexity, channel access time, delivery success ratio, and throughput. Based on our results, HomeTDMA has an advantage over CSMA on channel access time, throughput and delivery success ratioIn the case of complexity, HomeTDMA is more complex compared to CSMA. Thus, CSMA is more appropriate in wireless sensor networks (WSNs) where memory, energy, and throughput are important parameters to be considered. However, HomeTDMA has a natural advantage of collision free medium access and is very promising for home networks where a reliable transmission or data transfer and congestion control is highly preferred.

Purpose: This study is a descriptive research conducted for looking into the role awareness level. role conflicts, and job satisfaction among professional home care nurses in the field of hospital based home care nursing service. Method: 154 specialized home care nurses in 63 hospitals and clinics that are implementing home care programs were subject to the study. Result: 1. The level of role awareness among professional home care nurses was $4.47\pm0.41$ on average out of 5. 2. The average score for role conflicts was $3.87\pm0.61$ out of 5. 3. In terms of job satisfaction level. $3.33\pm0.71$ was scored out of 5. 4. It has been discovered that there are statistically significant positive correlations among role awareness level, role conflicts(r= .224, P= .005), and job satisfaction level(r= .166, P=.040), while a negative correlation was detected between role conflicts and job satisfaction level(r=-.210, P= .009). Conclusion: The level of role awareness among professional home care nurses in the field of hospital based home care nursing service was very high and job satisfaction level was high when the level of home care nursing antecedents was high and the organization structure of working place was independent. But the level of role conflicts coming out of the weakness of job-supporting system was high. So the realistic alternative such as the improvement of working environment by administrative, institutional support, is required to make up for this problem in the future.

Purpose : This study compared the cost-effectiveness ratio of physical therapy in health centers and home physical therapy, two physical therapy methods for home-bound stroke patients, and clarified the economic validity regarding the effect of home physical therapy. Methods : To measure and compare the cost and effectiveness of the two physical therapy methods for stroke patients, subjects were recruited based on in-hospital and home physical therapy. Among the entire data collected, 82 and 90 participants were selected for in-hospital and home physical therapy, respectively. To measure costs, regarding both in-hospital and home physical therapy, direct cost and indirect cost for patients, family, medical institutes, and the government were measured. In addition, activities of daily living were measured in both methods to measure their effectiveness. Through collected data, the cost-effectiveness and incremental cost-effectiveness ratios were analyzed. Results : Based on the analysis of cost-effectiveness, home physical therapy showed lower cost-effectiveness than in-hospital physical therapy. Furthermore, the incremental cost-effectiveness ratio also showed a difference, which implied home physical therapy could have high effectiveness compared to cost. Conclusion : Based on these results, home physical therapy could be considered as an alternativeto other methods of physical therapy, for home-bound stroke patients. In addition, the result of thisstudy contribute by providing evidence that home physical therapy offers economic benefits and canbe more effective in treating home-bound patients when policy decisions are made to establish a home physical therapy system.
