The prolongation of life expectancy has expanded the duration of marriage in old age. In the meanwhile, the change of life style emphasizing privacy and sociodemographic environment favoring independent living has increased the number and proportion of the elderly living with spouse only. This study, focusing on those aged 60 and over who live with spouse only the elderly, explores their marital relationship. The study pays a special attention to compare whether and how the satisfaction on the relationship with spouse would differ between husband and wife. The ordered logit model analysis is conducted based on the nationwide survey '2008 Korean National Survey of Welfare Need in the Elderly'. The results show that the marital relationship satisfaction of husbands is influenced by their own characteristics but hardly affected by his wife's. In contrast, the satisfaction of wife is influenced by husband's characteristics as well as hers. These finding reflect that women are more strongly family-centered and dependent on their husband.

The innovation activity is an important factor for sustained growth in nations and firms. Particularly, the problem of appropriation of results of the innovative activity is very important for innovators since it enables them to enjoy the profits generated by their innovations. This study is intended to empirically analyse relative preference of patent and secrecy that is affected by characteristics of innovators and results of innovation using data from '2005: The Korean Innovation Survey' and Ordered Logit method. As a result of this study, the preference for a specific mechanism is clearly revealed in product innovation rather than process innovation. Also, in most research, questions results of analysis are equal to the previous studies and the nature of appropriation methods. However, the result of a research question based on sources of information is very different from previous researches. This study utilized more recent data than previous studies. This result reflects that existing patterns have been changed during recent period.

Due to the decrease in the school-age population and government regulations, universities have made great efforts to secure their own competitiveness. In particular, the selection of universities with financial support based on the recent evaluation of the Ministry of Education has become a major concern enough to affect the existence of the university itself. This paper extracts three-year data from 124 major private universities nationwide, and quantitatively analyzes the variables of major universities selected as self-improvement universities, competency reinforcement universities, and universities with limited financial support. As a result of estimating the selection of self-powered universities using the ordered logit model by hierarchically inputting 12 variables, student competitiveness in the metropolitan area (1.318^**), Educational Restitution Rate (4.078^***), University operation expenditure index rate (1.088^***) values were found. Significant positive coefficient values were found in the admission enrollment rate (45.98^***) and the enrollment rate (13.25^***). As a result of analyzing the marginal effects, the increase in the rate of reduction of education costs has always been positive in the selection of self-powered universities, but it was observed that the rate of increase decreases in areas of increase of 150% or more. On the contrary, the probability of becoming a Em-powered university was negative in all sectors, but on the contrary, it was analyzed that marginal effects increased at the same time point. On the other hand, the employment rate of graduates was not able to find direct significance with the result of the selection of Self powered universities. Through this paper, it is expected that each university will analyze the possibility and shortcomings of the selection of Self powered universities in policy making, and in particular, the risk of dropout of selection for the vulnerable field can be predicted using marginal effects. It can be used as major research data for both university evaluators, university officials and students.

This study aims to analyze affecting factors on life satisfaction level of the women and partial effects using Ordered Logit Model. For this purpose, socio-economic factors are selected as major independent factors. And the data used was from the third 'Korea Welfare Panel Study'. Analysis shows that social life factors such as the satisfaction of leisure activities, social relationships, family member communication, and positive attitude to life had positive effects with the life satisfaction level of the women. However, economic factors such as home ownership, disposable income had a lower positive impact compared to social life factors. While, satisfaction level of women is negatively related with family member discordance, and classified low-income families. On the basis of these results, government should pay more attention to improve facilities and software that could meet women's needs of social life satisfaction.

Using the National Children and Youth Panel Survey (2010) data, this study examines the self-care after school experienced by elementary school students. It argues the necessity of analysis on self-care days for understanding demanders' characteristics of after-school care policy. Based on the Ordered Logit Model, this study analyzes the determinants of self-care days among school-aged children. The main result of the analysis is that self-care days are also more likely to be increased among children with higher school grade, more sibling, lower mother's education, dual-earner family, two-parent family, multi-cultural family, and lower family income.

This study analyzes factors affecting the competitiveness of broadband over power line communication (BPLC) and predicts demand for the service, based on quantitative information about consumer preferences drawn from a survey of Korean consumers. Findings from the estimation suggest that, although consumers value some beneficial features of BPLC, to be competitive the speed and stability of its data transmission needs to be improved. Moreover, on the basis of a market simulation, we expect BPLC to occupy only a small portion of Korea's Internet access market in the future, a finding we expect would hold true for other developed countries whose Internet access markets are already mature.

Wireless data communication (WDC) services are increasingly penetrating the market. The two main alternative WDC technologies are wireless LAN and mobile Internet. Services based on these technologies display differences in quality attributes such as terminal device, data transmission speed, pricing scheme and so on. How consumers choose between these two alternatives will be determined by their preferences regarding such quality attributes. In turn, their preferences will affect the evolution of WDC services and related technologies. This study employs a conjoint analysis of consumer valuations of quality attributes of wireless LAN and mobile Internet services. Respondents rate hypothetical service alternatives featuring various combinations of quality attributes. By estimating consumer willingness to pay for the attributes of WDC services, the authors predict the evolution of WDC services and related technologies along various quality dimensions, make a comparison with the results of a previous study, and draw policy implications for national-and company-level R&D strategies.

This research attempts to provide an in-depth analysis of the public perceptions of inter-Korean economic cooperation. KDI survey data with a sample size of 1,000 were subjected to empirical analyses. By means of ordered logit estimations, we derive the following results. First, there is a significant effect of age on economic cooperation perceptions, where younger generations tend to be more negative. Second, the group who has positive view on the economic cooperation tends to prefer large-scale, domestic-entity-funded cooperation projects, whereas the group who has negative view tends to prefer small-scale projects and projects funded by international organizations. According to these results, prioritizing trade with the involvement of international organizations is likely to be an effective measure to alleviate potential political constraints and to achieve sustainable long-run economic cooperation systems when pursuing the economic cooperation.

This study examines how consumer attitudes toward food origin and health concerns influence beef purchasing behavior. Using data from the Korea Rural Economic Institute's food consumption behavior survey, we analyzed the frequency of purchasing domestic and imported beef. Results indicate that when not distinguishing between domestic and imported beef, perceptions of lower origin quality and higher health concerns are associated with an increase in purchasing frequency. However, such influences are statistically insignificant for imported beef. Further analysis reveals that for consumers exclusively purchasing domestic beef, these factors do not significantly impact purchasing frequency, while for consumers simultaneously purchasing both domestic and imported beef, these factors do significantly impact purchasing frequency.
