Purpose: In this study, eye-health inequity was investigated by analyzing the relationship between household incomes and eye-health of senior citizens. Further, this study suggested the preliminary data for establishment of public eye-health policy in order to improve low income senior citizens' life quality. Methods: The data from the 2009 Survey of Korea National Health and Nutrition Examination were analyzed in this study. The objectives of the KNHNE survey were over 65 year old group (1,668 people). Main factors of eye-health (visual acuity, cataract, pterygium, intraocular pressure, retinophathy, age-related macular degeneration, diabetic retinophathy, myopia, hyperopia, astigmatism, and anisometropia prevalence) were analyzed with t-test and chi square test. Results: Low income group revealed that refractive error rate and intraocular pressure were low, however, naked eye visual acuity and corrected visual acuity were high at 0.1 to less than 0.5. On the other hands, in the high income group, there was high prevalence of hyperopia. Cataract mainly occurred at low income group besides group which maximum corrected visual acuity was below 0.8 also highly showed cataract. Moreover, the prevalence of cataract showed that it related with smoking, drinking, occupation, and education level. Conclusions: Results revealed that there was inequity of eye-health which related with socioeconomic status of the elderly. Especially, the prevalence of cataract was correlated with life quality. Consequently, establishment of public eye-health policy seems to be required for eye-health inequity of low income senior citizens.

Our paper aims to estimate a household consumption function in the presence of liquidity constraints as well as household characteristics. Empirical findings from a Korean cross-sectional data (National Survey of Household Income and Expenditure) reveal that several family characteristics, such as household size, number of working members, children in school, and educational level and age of the household head, turn out to be critical determinants of household consumption. Especially, the influence of household size on consumption decision is shown to be highly significant, not only indirectly through its impact on household income, but also directly by affecting the household's preference for consumption itself. While, the other family characteristics primarily influences household income. Our paper distinguishes itself from existing literature in that it greatly improves the explanatory power of the estimated household consumption function by measuring the degree of the liquidity constraint rather than simply identifying its presence. Based on the assumption that the present value of human capital is a function of household characteristics, the degree of the liquidity constraint is represented by the underestimated portion of the human capital. Such a method of implementing the liquidity constraint is useful in treating various types of assets according to their liquidity. Finally, our estimated household consumption function is applied to decompose cross-sectional variances of consumption inequality. The analysis confirms that the overall alleviation in liquidity constraints in Korea after the 1997 currency crisis reduced consumption inequality despite the worsening of income inequality and changes in the demographic composition of family characteristics during the same period.

Since the 1980s, the western welfare states have experienced a wide spectrum of socio-economic changes; changes in population composition, the economic globalization, the post-industrialization, an increasing flexibility in the labor market. etc. This study examines the trend of poverty in welfare states, and analyzes how those socio-economic changes are related to it. For these purposes, this study first calculates the poverty indices for several years in 10 welfare states using the Luxembourg Income Study database, and then decomposes the index by subpopulation and income sources. Major findings of this study can be summarized as follows. First of all, the welfare state in general has experienced an increasing trend in the degree of poverty since the 1980s. In particular, poverty has greatly intensified in the United Kingdom and the Netherlands. Many other welfare states including Canada, Germany, Sweden, and Norway have also experienced substantial increases in poverty. The increasing trend of poverty is not wholly due to changes in population composition such as increases in the aging population and one-parent(mother) families. Contrary to the traditional belief, these population groups are not as much poor as the working-age population. In particular, the degree of poverty in the elderly is less severe than in the working-age group. Furthermore, since the 1980s the market income poverty in the aging population has shown a decreasing trend in many welfare states. The degree and trend of poverty in one-parent families vary greatly across countries, owing to the labor market and income transfer policies. The most important reason for the increasing poverty trend in the welfare state is that the degree of poverty has been deepening in the working-age population. Especially, the market income poverty of the working-age population has considerably increased in every country except the Netherlands. Structural changes in the economy and the labor market may drive the increasing trend of poverty. Further studies and deliberate anti-poverty policies are needed to tackle the factors relating to the increase in the market income poverty.

Purpose: The aim of the current study was to compare the vegetable and fruit intake between one person households and those living with family. Methods: The 24-hour recall data of 14,914 persons over 20 years old who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) from 2010 to 2012 were used for the final analysis. Consumption of non-salted vegetables and fruits (${\geq}400g/day$), fruits (${\geq}200g/day$), and kimchi (${\geq}120g/day$) was compared between one person households and those living with family. Logistic regression models were used to assess the associations between potential determinants and adequate vegetable and fruit intake. Results: After additional adjustments for age, household income, and total energy intake, no statistically significant differences in likelihood of low intake of nonsalted vegetable and fruit and kimchi were observed between one person households and those living with family. (Nonsalted vegetables and fruits: odds ratio (OR) = 1.15, 95% confidence interval (CI) = 0.79-1.68 for the men; OR = 1.25, 95% CI = 0.98-1.59 for women). However one person households have greater likelihood of low intake of kimchi than those living with family in women (OR = 1.72, 95% CI = 1.31-2.26). Conclusion: Although there were no differences in likelihood of low intake of non-salted vegetables and between individuals living alone and those living with family, women of one person households were great likelihood of low intake of kimchi compared to those living with family.

The regional differences between urban and rural areas make many diverse differences. There are various differences between urban and rural areas such as economic gap and cultural gap. There is also a difference between urban and rural areas in accessing and utilizing information. The purpose of this study is to clarify the relationship between the information gap and the income gap among farmers and fishermen groups, where information gap is considered to be more serious than other groups. In other words, we tried to examine whether the information gap between farmers and peasants affects the income gap. The purpose of this study is to analyze the relationship between informatization level and income of farmers based on the information gap index and survey results conducted every year by the government. The results show that there is a statistically significant positive relationship between the informatization level of farmers and household income. In addition, the trend of the regression coefficient is positive, suggesting that the government needs various informatization policies to increase the informatization level of farmers.

According to Statistics Korea, South Korea has entered the realm of the "aging society" with the rapid development of the country's population. Researchers anticipate that the extremely high (73%) ratio of real estate property to total assets for mid-age to aged households in South Korea that do not have a fixed income may cause serious problems in the future. For example, the real estate market in South Korea may be bombarded with properties listed for sale, causing the average property price to drop due to the abundant supply. Although this prediction may be reasonable, this concept has excluded the idea of pension (which is crucial as it can be considered a consistent and fixed income) due to the limited amount of available data thereon; as such, it is important to include this factor to improve the pertinent research. Thus, this research was conducted using the data from the $3^{rd}$ and $5^{th}$ Korea Retirement and Income Study. For the study results, it was found that variables such as net asset, gender, education, and number of family members have the same impact as that found in the previous studies. To extend from here, two new factors were introduced: the existence of pensions and the amount of pension received by a household. From there, it was found that the existence of a consistent and fixed income such as a pension has led to an increase in housing consumption, the area of interest of the authors.

Single-person households recently have been rapidly increasing and one reason may be the increment in elderly single-person. Since the change of living patterns is relevant to the government policy direction, it is important to understand how single-person households are clustered and which factors have influence on them. In this study, we tried to detect spatial clusters of single-person households and low-income elderly single-person households after adjusting for deprivation index. A recently developed fused lasso for Poisson data was used for data analysis and we provided the details on how to use it in R. From these analysis results, we observed the effect of socioeconomic level on the clusters and explained the reason why spatial clusters are shown after adjusting for deprivation index.
