The purpose of this study was to investigate the comparison of nutrient intake and metabolic syndrome between single person households and non-single person households in elderly subjects. We analyzed data from 2,903 subjects ≥ age 65 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2015. As a result, single-person households had lower income and economic ability, overall nutrient intake was deteriorated, and the proportion of high-carbohydrate intake was high, compared to non-single person households. After adjusting for potential confounders (sex, age, education, household income, economic activity, smoking status, alcohol consumption, walking frequency, health status, depression status, and dietary factors), the single-person household showed a tendency of 1.22-fold higher ORs of metabolic syndrome and 1.3-fold higher ORs of hypertriglyceridemia than the non-single-person household. We suggest that the single-person household may be associated with increased prevalence of metabolic syndrome and hypertriglyceridemia in the elderly subjects.

The purpose of this study was to analyze the types and characteristics of temporary small-sized housing units for single-person households. A document research method and case studies were used to analyze and classified the spatial characteristics and types of the temporary dwelling spaces since 2000. Findings of this study were as follows: temporary and simplified dwelling spaces were developed by the concept of impermanence for single-person households in modern society. In order to conform the concept of temporary dwelling for small-sized housing units of single-person households, the characteristics were divided into three aspects. 'Transporting' by wheel and rotation and vehicles, 'Transforming' by adapting, assembling disassembling, and folding unfolding, and 'Wearing Carrying' by inflatable and tented types. It attempted to resolve the concept of temporarity through the experiment so that they might apply to the space of contemporary city.

With the recent rapid increase in single-person households, food companies are releasing small packaging and small-capacity products regardless of product line such as beverages, fresh foods, and home snacks, and food consumption patterns are also changing. Meanwhile, as a series of accidents related to food safety occurred during cost-effective consumption pursuing price-performance, more consumers wanted to choose products that have been proven safe even with higher money due to food safety anxiety. Considering the concept of 'safety' of food, this study by using the 'ordered probit model' empirically investigated whether there is a difference in the degree of preference for safety in food consumption behavior between single-person and multi-person households. Summarizing the results, it was found that women rather than men, and elderly households among young and single-person households had a higher demand for food safety. The results of marginal effects considering food safety variables show that respondents with low frequency of delivery and take-out use are considering food safety more, and that single-person households are considering safety more than multi-person households. In the future, the population structure of Korea will continue to increase in single-person and elderly households, and women's economic activities will also continue to increase. Therefore, the growing home convenience food market needs marketing strategies to secure and emphasize food safety, such as sterilizing treatment technology for hygiene and safe container development from environmental hormones, and needs a lot of support and attention to meet changes in food culture trends and demographic structure.

최근 1인 가구가 급격히 증가하고 있으며, 그 증가의 원인 중 하나는 독거노인 수의 증가이다. 이러한 거주형태 변화는 필연적으로 정책적인 변화를 요구하므로 1인 가구의 공간적인 분포를 파악하는 것은 중요한 문제로 볼 수 있다. 또한 공간적인 군집이 나타나게 된 요인들에 대해 이해하는 것은 효율적인 정책 수립에 유리 할 것이다. 본 연구에서는 사회경제적인 불평등을 반영하는 박탈지수 (deprivation index)를 설명변수로 고려하면서 1인 가구와 저소득 독거노인에 대한 공간 군집 탐색을 하였다. 이를 위해서 fused lasso를 이용한 공간 군집 탐색방법이 사용되었다. 이 방법을 통하여 낮은 사회경제적 수준이 l인가구와 저소득 독거노인의 수에 얼마나 영향을 미치는지 확인하고, 박탈정도의 효과가 보정된 공간군집을 살펴보았다. 또한 정수형 자료에서 벌칙가능도함수를 이용한 공간 군집 탐색을 할 수 있도록 구현된 R패키지의 사용법을 자세히 소개하였다.

The number of households in the country is expected to rise from 16,420,000 in 2007 to 19,870,000 in 2030, an increase of 21%. This is because while the population itself decreases due to a low birth rate, the number of households rapidly multiplies with the increase of nuclear family and single-person households. The ratio of single-person household is increasing every year at demographics data. The design that suits their needs, however, is not fully explored yet. The purpose of this study is to find out single-person household's lifestyles, and to search and analyze users' needs for spatial composition according to their lifestyles, and then, propose a single-person housing's plan and direction.

This study was conducted to analyze the economic well-being of the elderly households based on the housing ownership and the housing costs, with the comparison between the coupled elderly and the single elderly. The results of this study were as follows: the household type was related to the housing ownership, showing that the single elderly households owned the housing less than the coupled elderly did. There was a difference in housing costs between the single elderly and the coupled elderly, showing the single elderly households had higher housing costs than the coupled elderly households. The housing ownership was significantly related, but the housing costs negatively related to the economic well-being of the elderly.

The purpose of this research is to compare housing wealth effects of home-owning single income couples (SIC) and dual income couples (DIC) on their non-durable consumption and to assess the effects by location, age groups, housing structure type, debt-to-asset ratio and employment status. Using the Korean Labor and Income Panel Study (KLIPS) of 2014, this empirical study identified 1,198 SIC households and 1,044 DIC households, and employed multiple regression analysis. The main results reveal that the difference of financial portfolios between SIC and DIC households was little but housing wealth effects were stronger among SIC households than DIC counterpart. It's evident that housing wealth effects were conspicuous for SIC and DIC households who were headed by wage earners aged over 40s, and resided in apartment outside the Seoul Metropolitan Area. However, household debt became a determinant in contradicting housing wealth effects of SIC and DIC households. While the household financial dimension was in proportion to income, DIC households didn't gain much financial security due to increasing expenditure. Further, this research imply that liquidity constraints explicitly posed a more serious threat to SIC households whose dependence on housing asset is larger than their counterpart.

Recently, the increase of single households are remarkable in Korean society due to various social and economic reasons such as aging and changes in values, and it is expected to bring many changes to social and economic structures and residential spaces. Increase of single households is a result of complex economic, cultural and social factors. It is because as the individual's financial independence increases due to elevated income and education level, the age of marriage is going up and the individualism, which values the individual's value rather than custom, is spreading. It is expected to accelerate further in connection with the changes in structure of population, such as a low birth rate and aging. As the number of single households is increasing, the development and marketing for single household products are actively growing. With the increase in consumption demand and need of growing single households, the multi-functional system furniture that can be efficiently and conveniently used in small spaces are needed, but the furniture manufactured in Korean companies are designed for regular housing and is not suitable for single households. Therefore, the aim of this study is to develop multi-functional system furniture can be freely used in the housing structure of single household and small spaces.

The purpose of the study was to investigate the wife and husband role division in household financial management between dual-income household and single-income household. Household financial management included the following five categories: financial planning, consumption/expenditure management, savings/investment management, risk management and credit management. Data for this research was collected through 610 married women living in Seoul, Korea. Using SAS-PC program, Chi-square and t-test Analyses were executed. The results showed that dual- and single-income households tend to have different perspectives on marital role division in household management. Wives of dual-income households had more significant roles in financial management rather than wives of single income households. Especially, wives of dual-income managed more active credit management and saving/investment management. On the other hand, wives of single-income households played a major role in making decision over cheap items than that of wives of dual-income household.
