In this study, we compared Korean retirees' retirement wealth adequacy with their subjective recognition and examined determinants affecting the retirement wealth adequacy. The data were drawn from the 2007 Korean Retiree Survey carried out by the Korean Investors Education Foundation. The major results of this study were as follows. The analysis suggested that Korean retirees(age 50 and over) were not well prepared financially. When using their assets(except for their residence), only 23.2% had accumulated enough wealth to meet their expenses for the remainder of their life. 25.7% of retirees subjectively considered themselves to be adequately covered. The comparison results showed that 23.8% of retirees' subjective recognition was not in accord with the estimation results. One of the most troubling groups is the 12.9% of retirees who were in the inadequacy group even though they considered themselves to be in the adequacy group. Retirement wealth adequacy determinants were quite different between objective adequacy and subjective recognition. Household income and ownership of a residence have positive effects on the retirement wealth adequacy. Also, the importance of retirement planning to retirement wealth adequacy is statistically confirmed. Based on these findings, This research suggests private retirement planning and political implications for retirees and preretired households.

It is essential in social policy evaluation to examine how effectively they protect people from social risks. The aim of this study is to evaluate the effectiveness of five income security programs of Korea in coping with poverty, using KoWEPs data. We analyse the coverage and adequacy of these programs, joint as well as individual, for each sub-groups. As a result, it was found that 35% of the poor get none of the benefits. The coverage and adequacy for the aged is rather high. However, for the working age people, the unemployed in particular, are very poorly covered and average benefits levels are very low. These findings imply that there are much room and demand for improvement of Korean income security program, especially for working age population.

Objectives: This study examined the personal, interpersonal and community factors related to food sufficiency and variety among Korean adults using data from the 2017 Community Health Survey. Methods: A total of 228,310 adults aged ≥ 19 years were classified into three groups: food sufficiency with variety, food sufficiency without variety and food insufficiency. Personal factors included sociodemographic characteristics, health behavior and health status. Interpersonal factors included social networking and social activities, and community factors included safety, natural environment, living environment, availability of public transportation and health care services. The association of food sufficiency and variety with interpersonal and community factors was assessed using multivariable logistic regression analyses. Results: Of the total sample, the food-sufficiency-without-variety group and food insufficiency group accounted for 31.5% and 3.2%, respectively. The sociodemographic factors associated with food insufficiency and non-variety were women, ≥ 65 years of age, with low education level, low household income, unemployed, single, and living in areas of small population sizes. There were significant differences in health behavior and health status, interpersonal and community factors among the three groups. Multivariable logistic regression analyses conducted after adjusting for confounding factors showed that lack of social networking and social activities and lower satisfaction derived from community environments were associated with the risk of food insufficiency and non-variety. Conclusions: Our results showed that interpersonal and community factors as well as personal factors were related to food sufficiency and variety. Therefore, public policies to help build social networks and participation in social activities, and improve community environment are needed together with food assistance to overcome the problems of food insufficiency and non-variety.

In this paper, we consider a characterization of a Guard Sufficiency Set(GSS) in the hierarchy of simple polygons. we propose the diagonals of a arbitrary triangulation of a polygon as a GSS when guards see the diagonals with completely visibility and both sides of the diagonal. we show that this can be a GSS in convex polygons, unimodal polygons, spiral polygons but this can not be a GSS in star-shaped polygons, monotone polygons, completely external visible polygons.

This study compared the financial status between the employed-elderly households and the unemployed-elderly households, focused on income adequacy, expenditure adequacy and net wealth adequacy. Using data from 1997 KHPS, the lower financial status of the unemployed elderly households were found. Nine measures of financial status were used : income, per capita income, income-to-needs ratio, expenditure, per capita expenditure, expenditure-to-needs ratio, net wealth, net wealth-to-income ratio and net wealth- to-expenditure ratio. The results of this study showed that unemployed elderly households had 68%~77% of income adequacy and 72%~83% of expenditure adequacy for employed elderly households. Holding for gender, age, education, earners in the household, living area and home ownership constant, although the gap was getting smaller, significant differences between the unemployed-elderly households and the employed-elderly households were persisted. The result of this study indicated that the unemployed-elderly households and the employed-elderly households can not be regarded ac homogeneous group when public policies are developed.

The purpose of this study is to establish the concept of the blind zone of social services and analyzing the conditions by children, the elderly, the disabled, and the poor. This study used the raw data of demand/supply of social service and sample size is 4,038. Results of the study were as follows. First, in terms of the coverage, the biggest blind zones of social service are the employment support and cultural service. These results were similar for all households. But, it is noteworthy that the size and proportion of blind zones of housing support services for children, counseling services for elderly are relatively big. Second, in terms of adequacy, the most serious blind zones of social service are health and the employment support service. Especially, the elderly, the disabled, and the poor are not the most adequate adult care services and children are community service. Based on such findings, this study suggests expansion of employment support services and health care, monitoring for the services analyzed to be over-supply, and intensive involvement of private sectors about the services provided by the government of a large blind zone.

This research aimed to setup the innovativeness, dependability of information, reliability, and sufficiency of information of a mobile eating out application as the precedence factor, and also aimed to present useful information regarding the mobile eating out application by verifying the effect on the continuous use satisfaction levels and long-term orientation for this mobile eating out application. The data collection carried out from February 1 to February 28, 2016, with 441 questionnaires collected from a total distribution of 500 copies, of which 396 were retained. SPSS 22.0 was employed for factor analysis and the reliability verification, while AMOS 22.0 was used for the covariance structure analysis meant to verify the presented research hypothesis. The results are as follows. First, there was found a significant positive effect (+) on continuous use from innovativeness and dependability. On the other hand, sufficiency and reliability appeared not to have a significant effect. Second, there was a positive increase in long-term orientation as continuous use increased. Third, long-term orientation increased in relation to innovativeness. On the other hand, sufficiency, dependability and reliability appeared not to have a significant effect on long term orientation. Accordingly, the useful implications for the eating out application based on the analysis results has been presented.
