This study investigated the situation of eating meals to identify factors influencing skipping breakfast and types of foods consumed for breakfast among adolescents classified by household type. Adolescents were found to consume mainly homemade meals for breakfast and dinner while consuming institutional foodservice at school for lunch. Percentage of skipping meals among adolescents was different by time of meals, and they skipped meals due to lack of time, which was different according to household type. Main food for breakfast was rice, and percentage of skipping breakfast was the highest in single parent households. Satisfaction of food-related life was lowest in grandparent households. Especially, satisfaction was highest if they had rice for breakfast. For influencing factors on skipping breakfast, social support, eating regularly, concern for origin, and single parent household were found to be significant. For influencing factors on types of foods consumed for breakfast, eating regularly, exercise, satisfaction of food-related life, and concern for food safety among adolescents were found to be significant. If adolescents in grandparent households had rice, they were less likely to skip breakfast.

This study compared the lifestyle patterns, dietary patterns, and health care practices of Korean middle-aged people by household type, and ultimately analyzed their relationship with different risk factors for the prevalence and severity of metabolic syndrome. We analyzed the data from 4,755 subjects who were from 40 to 64 years old, and gathered our sample from participants of the Korea National Health and Nutrition Examination Survey from 2013 to 2015. Our results showed that single-person households had lower economic income levels, lower subjective health statuses, and higher levels of food instability than households with two or more individuals. The incidence of metabolic syndrome was 1.64 times higher in single-person households than in households with two or more individuals. After adjusting for potential confounding factors (sex, age, education, household income, smoking status, health status, and dietary factors), single-person households showed 1.75 times higher hypertriglyceridemia ORs than non-single-person households. In the conclusion of our study, we suggest that middle-aged people in single-person households may be at greater risk for metabolic syndrome and hypertriglyceridemia.

Recently, with the development of deep learning technology, research on recognizing human behavior is in progress. In this paper, a study was conducted to recognize risky behaviors that may occur in a single-person household environment using deep learning technology. Due to the nature of single-person households, personal privacy protection is necessary. In this paper, we recognize human dangerous behavior in privacy protection video with Gaussian blur filters for privacy protection of individuals. The dangerous behavior recognition method uses the YOLOv5 model to detect and preprocess human object from video, and then uses it as an input value for the behavior recognition model to recognize dangerous behavior. The experiments used ResNet3D, I3D, and SlowFast models, and the experimental results show that the SlowFast model achieved the highest accuracy of 95.7% in privacy-protected video. Through this, it is possible to recognize human dangerous behavior in a single-person household environment while protecting individual privacy.

Purpose: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. Methods: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. Results: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system ($x^2$=13.89, p<.001) were significant, while the differences in the perception of depression ($x^2$=.02, p=.891) and coping methods ($x^2$=.34, p=.558) were not statistically significant. Conclusion: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

This study was conducted to provide basic data for evolving a strategy for the development of Vietnam's customized HMR program and formulating a marketing strategy by analyzing the characteristics and variations of HMR consumption behavior by household size. The results of the analysis were as follows: The number of single households using HMR as a general meal at home was higher than multiple-person households. Moreover, there was a high preference for 'ready to heat' and 'ready to eat' products, which are relatively easy to cook and prepare. It was observed that single households preferred department stores, hypermarkets, and convenience stores for purchasing HMR when compared to multiple households, and that single households preferred to acquire information through TV/radio and internet advertisements. Among the HMR selection attributes, single households valued taste, quantity, price, preparation process, preparation time, and ease of storage as important. Reflecting on the results of this study, when developing HMR in Vietnam, it is necessary to develop a product that can nutritionally replace the general meal with a focus on convenience. In addition, there is a need for products that possess various attributes such as convenience, health, and eco-friendliness.

The purpose of this study is to analyze the effects of the financial preparations for aging on the life satisfaction of single households are different according to their experiences of having been married or not, and thereby to suggest an alternative policy which differenciate single households with their exposure to married life from those without their exposure to married life. The analyzed data is based on social statistics in 2015 of the Statistics Korea, with 4,406 people, over 30, who are either never married singles or married but divorced or bereaved singles. Finding are, first, there was a statistically significant difference in financial preparations for aging between unmarried single households and married, and unmarried single households are more prepared than married ones. Second, life satisfaction of unmarried single households was higher than married ones. Third, the effects of the financial preparations for aging on the life satisfaction were shown from both groups, and married single households were more sensitive to the effect of financial preparations for aging on the life satisfaction.

The purpose of this study was to explore housing characteristics of young single- or two-person households in the U.S. metropolitan urban areas and determinants of their housing cost burden. Total 764 single-person households, 744 two-person households and 424 households with three or more persons were selected from the 2011 American Housing Survey public-use microdata for the study based on specific sampling criteria. The major findings are as follows: (1) In comparisons with larger households, single- or two-person households were characterized to be headed by younger householders, to have less income, and to have a greater proportion of households living in central cities of metropolitan areas, renting housing units, living in smaller size units or multifamily structures; (3) housing cost of single- or two-person households were significantly less than a larger households while housing costs per unit square footage (SQFT) of single- or two-person households was significantly greater; (4) regardless of the household size, there are many household headed by young college graduates paying too much of their income for housing, and single-person households were found to have the greatest housing cost burden; and (5) a linear combination of low-income status, monthly housing costs per unit SQFT, annual household income, and unit SQFT per person was found to be most efficient to predict single- or two-person households with housing cost burden.

The purpose of this study was to investigate the effects of social supports and health on the depression of the rural elderly according to their household patterns. Data were collected from 1,000 of the elderly over 65 living in rural Korea. A questionnaire was used with direct interviews and was analyzed through descriptive statistics, ANOVA, and a multiple regression analysis. The major findings of this study are as follows. First, the general characteristics, social supports, and health of the rural elderly are significantly different according to their household patterns. Second, depression in the rural elderly is also significantly different according to household patterns; elderly people in a single household report greater depression than elders in a coupled household or those in a household with a child. Third, satisfaction with health conditions and nutrition management variables has a significant influence on the depression of the rural elderly in all household patterns. Fourth, there are differences among variables that affect depression of the rural elderly according to their household patterns.

Accurate household projections are essential for sectors such as housing supply and tax policy planning, given the rapid social changes like declining birthrates, an aging population, and a rise in single-person households that impact household size and type. Korea introduced its first register-based census in 2015, transitioning from five-year general survey-based approach to an annual administrative data-based census. This change in census allows for more frequent and effective capturing the rapid demographic shifts and trends. However, this change in census has caused challenges in future projection by the existing household projection model due to the rapid dynamics. This paper proposes a new household projection method, the N-point Modified Exponential Model (MEM), that accurately reflects register-based census data and mitigates the impact of rapid demographic changes, in three types: the Weighted N-point MEM, the Regression-based N-point MEM, and the Rolling Weighted N+point MEM. Using register-based census data from 2016 to 2020 to forecast household headship rates by age, household size, and household type to 2051, the N-point modified exponential model outperformed the existing model in both long- and short-term forecast accuracy, suggesting its suitability as a future household projection model for Korea.

Determinants of consumption patterns of elderly couple and elderly single were investigated using the 1996 National Survey of Family Income and Expenditure by National Statistical Office. There were large differences in consumption patterns between the elderly couple and single in terms of monthly expenditures and average budget shares of individual consumption items. Consumption functions of individual items were estimated using double-log function. Major determinants of consumption functions were income, overspending behavior, educational level of householder, and net worth for both groups, householder's job status and city residence mainly for elderly couple, and age of householder mainly for elderly single. In addition, income elasticity of elderly households was larger than net worth elasticity for all consumption items.
