The purpose of present study is to examine the effects of the elderly's assets on life satisfaction, and to examine the indirect effects, such as financial and emotional support exchange with their children, between their assets and life satisfaction. For this study purpose, the 5th data of the Korean Longitudinal Study of Aging (KLoSA) was used. Abstracted from the data, 1,977 cases only for the elderly over 65-year-old were analyzed by employing SPSS 23.0 and SPSS Process Macro. The analysis results are summarized as follows. First, the assets of the elderly had a positive direct effect on the satisfaction of life. Second, the elderly's assets indirectly affected the satisfaction of life through the financial support exchange with their child(ren). Lastly, the elderly's assets indirectly affected the satisfaction of life through the emotional support exchange with their child(ren). Based on these results, this study suggests practical and political implications in terms of social welfare for the elderly's life satisfaction, so as to facilitate the elderly's assets accumulation, and to enhance support exchange between the elderly and their child(ren).

New communication and information technologies such as the Internet are space-adjusting technologies. The Internet changes the spatial proximity by improving the connections between people and organizations separated by geographical distance This paper examines the digital position of individual nation-states on a global cyberspace. The number of inter-domain hyperlinks embedded in websites for 47 nations was gathered using the AltaVista in 2001 Data were also obtained on the geographical distance among the nations. The results indicate that the u.s. is the most central nation on the global cyberspace, followed by the U.K., Germany, Australia, Canada, Italy, France, China and Japan. The most peripheral nations are Uruguay, Luxemburg, and UAE. It also examines the relationship between the digital positions of 47 nations and their physical locations. The results indicate that digital structure on the cyberspace is not significantly related to geographical distance among those nations.

This study aims at exploring the transnational care for family members back home among the Nepalese marriage immigrant women in Korea on the bases of some transnational care practices like remittances, virtual intimacy through information and communication technologies, visit to Nepal, and invitation of family members to Korea. This study argues that in order to understand migrant women's care practices properly, Nepalese marriage immigrant women should be considered as 'being in-between' the societies and cultures of Nepal and Korea. This study identifies the characteristics of transnational care practices of Nepalese women are closely related to the role expectation for the eldest daughter as well as whether or not migrant women have children, jobs, and original family member in Korea. Furthermore, this study highlights that migrant women's transnational care practices should be considered as 'reciprocal exchange of cares' between marriage women and their family members rather than one-way benefits going to the latter.

While the importance of adopting cloud computing service has been emerged, comparatively little research has been conducted on examining factors of an individual user's intention to switch toward cloud computing service. Hereafter, this study presents and empirically tests users' intention to switch to cloud computing. Our model posits that the characteristics of cloud computing such as effectiveness, economics, accessability, switching cost, security concern, and satisfaction toward existing IT service to cloud service affect perceived value, which in turn, influences intention to switch. An experimental study using student subjects provided empirical validation for our proposed model. Survey data from 204 respondents was used to test the model using partial least square analysis. As the result of the analysis, five hypotheses out of seven hypotheses were supported. According to our results, among the characteristics of cloud computing, effectiveness, economics, switching cost, and security concern were found to have significant impact on users' intention to switch that mediated by perceived value. Based on our research findings, we hope that this research will stimulate researchers' interest in the emerging area of cloud computing adoption.

This paper examined, using three indicators, urban area rate, urbanization rate and urban population density upon the status of urbanization since the 2000s in Southeast Asia. This study also carried out an empirical analysis on the effects of urbanization on economic growth using the Williamson's inverted U-shape hypothesis. In addition, this study calculated the thresholds by which urbanization starts to have positive effects on economic growth by using estimated coefficients, and comparatively analyzed each Southeast Asian country's status. The empirical analysis results opposite to the Williamson's hypothesis. This means that the hypothesis asserting that urbanization has positive effects on economic growth in a country with low economic development phase and income level, but that urbanization can have negative effects on economic growth, if a country's income level is beyond a certain level(threshold), is not supported in this study. In summary, the economies of agglomeration represented as localization economy and urbanization economy is realized to some degree in terms of urbanization in Southeast Asia. Also, urbanization in Southeast Asia has positive effects on economic growth through knowledge spillover, the active exchange of ideas and productivity improvement. In examining the meaning of Southeast Asia's urbanization, policy consideration needs to be conducted, and efforts should be made to maximize the positive effects of the economies of agglomeration and knowledge spillover on economic growth.

A series of anion exchange composite membranes were prepared and characterized for electro-dialysis process used in the removal of toxic anion and cation polutants in groundwater or wastewater. The membranes were prepared as follows; first, porous poly(ethylene) (PE) substrates were fully impregnated with monomer mixtures with various ratio of vinylbenzylchloride (VBC), divinylbenzene (DVB) and ${\alpha},\;{\alpha}$-azobis(isobutyronitrile) (AIBN). Second, they were thermally polymerized to yield crosslinked poly(VBC-DVB)/PE composite membranes. Finally, the membranes were treated in trimethylamine (TMA)/acetone to give $-N^+(CH_3)_3$-containing poly(VBC-DVB)/PE membranes. The basic membrane properties such as ion exchange capacity (IEC), electric resistance and water content of the resulting membranes were measured as a function of VBC/DVB and TMA/Acetone content. As a result, the composite membranes showed lower electric resistance, lower water content and higher IEC than commercial anion exchange membranes (AMX, Astom) due to thin PE substrates, indicating that the composite membranes could be successfully applied to the electrodialysis for water treatment.

An energy pile is a novel type of ground heat exchangers (GHEX's) which sets up heat exchange pipes inside a pile foundation, and allows to circulate a working fluid through the pipe for exchanging thermal energy with the surrounding ground stratum. Using existing foundation structure, the energy pile can function not only as a structural foundation but also as a GHEX. In this paper, six full-scale energy piles were constructed in a test bed with various configurations of the heat exchange pipe inside large-diameter cast-in-place piles, that is, three parallel U-type heat exchangers (5, 8 and 10 pairs), two coil type heat exchangers (with a 500 mm and 200 mm pitch), and one S-type heat exchanger. During constructing the energy piles, the constructability of each energy pile was evaluated with consideration of the installation time, the number of workers and any difficulty for installing. In order to evaluate the thermal performance of energy piles, the thermal performance tests were carried out by applying intermittent (8 hours operating-16 hours pause) artificial cooling operation to simulate a cooling load for commercial buildings. Through the thermal performance tests, the heat exchange rates of the six energy piles were evaluated in terms of the heat exchange amount normalized with the length of energy pile and/or the length of heat exchange pipe. Finally, the economic feasibility of energy pile was evaluated according to the various types of heat exchange pipe by calculating demanded expenses per 1 W/m based on the thermal performance test results along with the market value of heat exchange pipes and labor cost.

Purpose: Terminal cancer influences on patients as well as their family members. This research was performed to evaluate the quality of lift of primary family caregivers and to investigate the influencing factors. Methods: The results of survey were collected from 81 family caregivers who were taking care of hospitalized terminal cancer patients at an oncology department of university hospital in Daejeon from March 2005 to January 2006 with questionnaires. The questionnaires were consisted of the general characteristics of the subjects, and 36-items short-form Health Survey (SE-36) Korean version to evaluate the quality of life of family caregivers, the characteristics of patients and family caregivers' caring trait. Results: Family caregivers' mean (${\pm}SD$) SF-36 score was 47.9 (${\pm}20.7$). Influential factors on family caregivers' life quality were daily raring hours, economic burden, type of treatment; only supportive care, caring duration, sex, the numbers of ADLs (activity of daily livings) items that patients needed help in order by stepwised multiple logistic regression analysis (overall $R^2=0.639$, P=0.044). Conclusion: Daily raring hours and economic burden were two influential modifiable factors on family caregivers' quality of life. Therefore, social supportive systems are required to reduce family caregivers' daily caring hour and economic burden.

This paper analyzes the pubic nature of New Genre Public Arts. It is very sensitive to the social issues and supports democracy and communities with the diverse civic participation. Therefore, it is be widely known without doubt that new genre public arts is more public in nature compared to the previous public arts. This research observes the practices of new genre public art and focuses on the problems of the revealing nature of new genre public art through the analysis of the interrelations among government, artists, and the residents by through observation on the , Seoul City Gallery project from October 2008 to January 2009. The implementation of the project is divided into three constituent parts: local government for funding, artists for planning and implementing, and residents. Local government supports and commands the public art works to create more competitive and harmonious city. Artists emphasize the revitalization of community and take the residents as the passive objects of enlightenment. Whereas, the residents hope to use the funds to improve economic conditions. Artists accept the top-down commands of government, whereas residents tend to passively participate and become objects for enlightenment by artists, after all, might be alienated by the project. These kinds of communications and relationships raise the issue of the possibility of failure of public arts projects.
