The purpose of this study is to examine the factors related to leisure time to understand middle-aged one-person households. Data are from the recent survey of lifetime use in 2014 by Statistics Korea(N=1,138). Middle-aged one-person households aged 40-59 years were categorized into four groups by marital status (unmarried/married/widowed/divorced). Major results were found as follows: First, the total leisure time per day was 238 min in the middle-aged one-person households. The majority of the total leisure time was spent on 'fellowship & leisure activities'(204 min on weekdays, 283 min on weekends). Especially, time spent on real-time TV watching hours was the longest, as long as 89 min on weekday and 150 min on weekends. Second, gender differences were significant in terms of leisure time use in the middle-aged one-person households. Females spent less time on leisure than their male counterparts on both weekdays and weekends. In addition, gender differences related to marital status were significant. Third, on weekdays, the determinants of leisure time use among the middle-aged one-person households were health and type of employment for 'participation & volunteer activities', and gender, age, marital status, and type of employment variables for 'fellowship & leisure activities.' On weekends, time spent on 'participation & volunteer activities' were influenced by marital status, residential area, and type of employment, while time spent on 'fellowship & leisure activities' were significantly related to gender, type of employment, type of job, holiday system, and income.

Purpose: Based on Anderson's model of health service utilization, we investigated the factors that affect the influenza vaccination status in Korean adults aged 50-64 years, who live alone. Methods: Data of 194 Korean adults aged 50-64 years, who live alone were obtained from the Korea National Health and Nutrition Examination Survey 7th Edition (2016-2018). Descriptive statistics and a multiple logistic regression model were used for statistical analysis. Results: The influenza vaccination rate in the study population was 39.3%. Educational status and health behaviors such as smoking habits and regular medical check-up were associated with the influenza vaccination rate in Korean adults aged 50-64 years, who live alone. Multiple logistic regression analysis showed that educational level lower than middle school graduation (odds ratio [OR] 2.02), non-smoking status (OR 1.98), and lack of regular medical check-up (OR 0.62) were significantly associated with the influenza vaccination rate in Korean adults aged 50-64 years, who live alone. Conclusion: The influenza vaccination rate in Korean adults aged 50-64 years, who live alone, is relatively low; therefore, policies should be implemented to improve the influenza vaccination rate in this population. Influenza vaccination in single households was affected by health promotion activities; therefore, interventions are warranted to encourage overall health promotion activities.

Recently, one-person households have surpassed nuclear families. One-person households are expected to have many problems with health due to an irregular life style and a tendency to be more isolated from society. In addition, we need to divide the generations and survey each generation due to differences in one-person household factors and characteristics as well as the unique physical conditions of each generation. Therefore, based on the sixth Korea National Health and Nutrition Examination Survey, this survey examined health behavior differences between one-person households and non-one-person households according to generation (respectively) as well as studied how one-person households and health behavior influence subjective health conditions. The major result of this survey is as follows. First, one-person households reveal a higher rate in the negative health behavior than non-one-person households. Second, the physical activity of all households reveals a high rate of non-activity. Third, health scores of one-person households are lower than that of non-one-person households; consequently, the analysis of health scores for one-person households and non-one-person households indicated that the middle age health scores for one-person households have been lowest in generations. Fourth, the factors that influence subjective health conditions indicated that one-person household and health behavior has meaningful influence; in addition, the subjective health condition of one-person households are lower than non-one-person households under controlled health behavior.

The aim of this study is to evaluate the possibility of treating slaughterhouse by-products using microbial electrolysis cells (MECs). The diluted pig liver was fed to MEC reactors with the influent COD concentrations of 772, 1,222, and 1,431 mg/L, and the applied voltage were 0.3, 0.6, and 0.9 V. The highest methane production of 5.9 mL was obtained at the influent COD concentration of 1,431 mg/L and applied voltage of 0.9 V. In all tested conditions, COD removal rate was increased as the influent COD concentration increased with average removal rate of 62.3~81.1%. The maximum methane yield of 129~229 mL/g COD was obtained, which is approximately 80% of theoretical maximum value. It might be due to the bioelectrochemical reaction greatly increased the biodegradability of pig liver. Future research is required to improve the methane yield and digestibility through optimizing the reactor design and operating conditions.

A studio type urban lifestyle housing was recently introduced as a new urban multi-housing typology. It was particularly created to meet the increasing housing demand of one-person households due to the population change and the shortage of housing supply. However, some concerns have been raised, because the government's policy has been focused on expanding housing supply by easing certain legal regulations in construction. Poorly planned and managed urban lifestyle housings might degrade living conditions for one-person households and ultimately harm urban environments. As such, this research is conducted to investigate the design characteristics of the studio type urban lifestyle housing from selected construction precedents in Seoul. Critical evaluations are made for the facilities and uses in site plans, unit plans, and shared public spaces. As a result, problem areas are found in the lack of design varieties, privacy protection in units, control of natural environment conditions, and the absence of community spaces. Improvement strategies can be suggested by comparing with some overseas' housing precedents: Design variations can be extended through flexible structure, facility, and furniture systems. Privacy and natural environment can be controled through the integration of interior space configurations and exterior envelope systems. The housing policy needs to be reconsidered to improve a variety in design, residents' social interaction, security, and management. Thereby, the studio type urban lifestyle housing should be holistically approached in terms of design and policy to enrich urban living experiences by residents and communities.

Purpose: This study compared health behaviors and disease prevalence between one-person women and multiple-household women in Korea. Methods: This study used the 2013 data from the Korean Community Health Survey (KCHS). A total of 89,807 women, aged 19-64 years were included in this study. The data was analyzed using descriptive statistics and Chi-square test. Moreover, statistical processing was performed using the SPSS 21.0. Results: Among adult women, one-person households women was 6.2%. One-person household women were older than multiple-households women, and multiple-households women were less likely to exercise regularly. And disease prevalence was higher in one-person household women than in multiple-household women. Conclusion: Residence characteristics should be considered in developing a public health program to reduce or increase modifiable health behaviors and disease prevalence. The findings from this study suggest that policies to improve the support for healthcare of one-person household women is necessary.

We examined if intergenerational proximity might be associated with upstream financial transfer from adult children to older parents, and whether adult child gender might moderate the association. We considered siblings' proximity to parents, as well as that of the adult child. Prior work conducted in the US and other countries has suggested that children living further from parents might provide financial support to compensate for instrumental support provided more by siblings living closer to parents. Data were drawn from the Korean Longitudinal Study of Ageing (2014). Our analytic sample consisted of older adults 60+ and their children aged 35 and 55. None of the children co-resided with parents. Parental households consisted of either widowed individuals or married couples. For within-family analyses, fixed effects and random effects regression models were estimated. Results suggest first, sons living within a 30-minute distance, or within an hour to two-hour distance provided more monetary support to married parents compared to daughters. Second, contrary to existing findings, greater financial assistance was provided by sons and daughters when no children lived within an hour distance from their parents. For widowed parents living alone, intergenerational proximity was not associated with the amount of financial transfer from adult children.

저용량 에어컨의 압축기에 많이 사용되는 Single rotary 방식은 하나의 피스톤만을 채용하여 가격적인 면에서 큰 이점을 가진다. 그러나, 압축기 모터가 1회전할때 마다 압축과 토출을 단 1회 거치게 되므로, 부하변동을 심하여 진동이 많이 발생하는 단점이 있다. 이러한 단점을 보완하기 위하여 Single rotary를 사용하는 에어컨 제품에서는 저속에서의 운전을 회피하거나 하나의 운전점에 대한 전향보상기를 채용하여 진동을 저감시켜 왔다. 본 논문에서는 모든 운전점에서 보상이 가능하도록 압축과 토출로 인한 부하의 패턴에서 각 주파수 성분을 분석하여 자동으로 부하 토크를 보상하는 알고리즘을 제안한다. 제안된 방법은 가장 영향이 큰 1차와 2차 주파수 성분의 속도 리플의 양을 FFT 하고, 그 양이 작아지는 방향으로 부하 토크를 전향 제어방식으로 인가하는 방식이다. 제안된 방식을 이용하여 저속 운전에서 진동이 저감 되는것을 실험을 통하여 보였다.
