Research on micro-level assessment of the changes of socio-economic status following health interventions is very scarce. The use of household asset data to determine wealth indices is a common procedure for estimating socio-economic position in resource poor settings. In such settings information about income is usually lacking, and the collection of individual consumption or expenditure data would require in-depth interviews, posing a considerable risk of bias. In this study, we determined the socio-economic status of 213 households in a community population in an island in the north-western Tanzania before and 3 year after implementation of a participatory hygiene and sanitation transformation (PHAST) intervention to control schistosomiasis and intestinal worm infections. We constructed a household 'wealth index' based housing construction features (e.g., type of roof, walls, and floor) and durable assets ownership (e.g., bicycle, radio, etc.). We employed principal components analysis and classified households into wealth quintiles. The study revealed that asset variables with positive factor scores were associated with higher socio-economic status, whereas asset variables with negative factor scores were associated with lower socio-economic status. Overall, households which were rated as the poorest and very poor were on the decrease, whereas those rated as poor, less poor, and the least poor were on the increase after PHAST intervention. This decrease/increase was significant. The median shifted from -0.4376677 to 0.5001073, and the mean from -0.2605787 (SD; 2.005688) to 0.2605787 (SD; 1.831199). The difference in socio-economic status of the people between the 2 phases was highly statistically significant (P<0.001). We argue that finding of this study should be treated with caution as there were other interventions to control schistosomiasis and intestinal worm infections which were running concurrently on Kome Island apart from PHAST intervention.

The aim of the study was to investigate prevalence of obesity among housewives residing in apartments in Taegu city and any relationship of obesity with various factors. Hundred three housewives aged 30-49 years living in apartments (over 30 pyung) were interviewed for socio-economic status, food habit, food intake by a convenient questionnaire, and daily activity by the 24-hour recall. Their weight, height and triceps skinfold thickness were measured. The results were summarized as follows: 1) The percentages of subjects and their spouses with college and higher education were as much as 53.6% and 83.5%, respectively. The commonest family size was four members with two children. 2) The percentages of subjects classified as underweight, normal, overweight, and obesity according to relative body weight(RBW) were 4.9, 44.7, 24.3 and 26.2, respectively. Twenty four percent belonged to obese group according to body mass index(BMI$\geq$25). 3) Food habit score was 12.4 points in average and judged 'good'. The average of daily energy intake was 2247㎉ which corresponded to 112% of RDA and intakes of nutrients except iron exceeded RDA. The means of food habit score and energy intake were not significantly different among 4 groups. 4) Multiple regression analysis was tested to explain a relationship between fatness and various factors. The equation, BMI=25.216+(0.836$\times$family size)-(0.309$\times$education, years)-(0.00503$\times$household work time, minutes), indicates that fatness of housewives was related with family size(+), educational level(-) and household work time(-). These relationships were statistically significant(p<0.001) and R2 (coefficient of determination) was 0.237.

This study examines whether the widening gap between income groups is worsening in the distribution of time use, similar to the worsening of income distribution after the IMF. To do this, we conducted multilevel analysis (HLM) on six countries including France, the Netherlands, Spain, the United Kingdom, the United States and Korea. The results of the analysis are as follows. First, in all countries, low income groups have a longer paid working time and shorter leisure time. Second, the low income groups in Korea have the longest paid work time and the shortest leisure time, the lowest level of work-leisure balance, and this aspect has not recovered since the IMF. Third, as the result of multilevel analysis, the lower the household income, the more time paid labor increased and the work-leisure balance decreased. Fourth, while average annual working hours increase paid working time, the expansion of family policy expenditure, redistribution policy and income maintenance policy has reduced it. Fifth, the annual average working hours decreased the work-leisure balance, but the family policy expenditure, the redistribution policy and the income guarantee policy increased the work-leisure balance. The significance of this study is that after the IMF, not only the income distribution but also the inequality among the income class in time use has deepened. Based on the results of the research this study suggests the reinforcement of labor time regulation, the activation of parental leave system, the realization of the income replacement rate, the expansion of the policy related to income redistribution, and the complementary development of the income guarantee and the time guarantee policy as the policy intervention strategy that restructures time.

This study was attempted in order to measure the level of Korean people's social capital and their multicultural acceptance, and to explain the relationship between the sub-factors of social capital(trust, reciprocity, and participation) and the multicultural acceptance. Furthermore, this study aimed to examine the relative influence of the sub-factors of social capital on the multicultural acceptance and to suggest which social capitals should be reinforced. Data on 'social capital' and 'multicultural acceptance' used in this study were obtained from the data of the 8th Korean General Social Survey (KGSS) in 2010. The results of analyses are as follows. First, social capital was lower with increase in age (F=28.18, p<.001), and higher with increase in academic qualification (F=15.49, p<.001), and total household income (F=8.85, p<.001). Second, the multicultural acceptance was higher in men (t=9.98, p<01) and lower with increase in age (F=27.29, p<.001), and higher with increase in academic qualification (F=28.99, p<.001), and total household income (F=11.92, p<.001). Third, among the three social capital factors influencing the multicultural acceptance, 'trust' was found to have a significant positive (+) effect. Based on these results were suggested various strategies for enhancing Korean people's multicultural acceptance.

In the recent modernized world, utilization of natural resources (renewable & non-renewable) is increasing drastically due to the sophisticated life style of the people. The over-consumption of non-renewable resources causes pollution which leads to global warming. Consequently, government agencies have been taking several initiatives to control the over-consumption of non-renewable natural resources and encourage the production of renewable energy resources. In this regard, we introduce an IoT powered integrated framework called as green home architecture (GHA) for green score calculation based on the usage of natural resources for household purpose. Green score is a credit point (i.e.,10 pts) of a family which can be calculated once in a month based on the utilization of energy, production of renewable energy and pollution caused. The green score can be improved by reducing the consumption of energy, generation of renewable energy and preventing the pollution. The main objective of GHA is to monitor the day-to-day usage of resources and calculate the green score using the proposed green score algorithm. This algorithm gives positive credits for economic consumption of resources and production of renewable energy and also it gives negative credits for pollution caused. Here, we recommend a green score based tax calculation system which gives tax exemption based on the green score value. This direct beneficiary model will appreciate and encourage the citizens to consume fewer natural resources and prevent pollution. Rather than simply giving subsidy, this proposed system allows monitoring the subsidy scheme periodically and encourages the proper working system with tax exemption rewards. Also, our GHA will be used to monitor all the household appliances, vehicles, wind mills, electricity meter, water re-treatment plant, pollution level to read the consumption/production in appropriate units by using the suitable sensors. These values will be stored in mass storage platform like cloud for the calculation of green score and also employed for billing purpose by the government agencies. This integrated platform can replace the manual billing and directly benefits the government.

This research is based on open data from the National Library Statistics System and Seoul Survey 2020 from Seoul to analyze the Seoul citizens' usage of public libraries. For such purposes, this research compared and diagnosed the condition of public libraries services at 25 districts of Seoul, focusing on objective indicators of library management and general usage records to understand the correlations between the two. Objective indicators such as budgets, human labor, the number of books, and total ground area were compared with usage records of different classes of Seoul citizens, organized by the citizens' place of living, educational background, and monthly household income. As a result of the research, the correlation between the objective indicators and public usage records of different classes was confirmed. Seoul citizens' usage of public libraries and reading tendency were identified. In addition to, a balanced development of the public libraries in Seoul was proposed to overcome regional disparities and leveling the service level by investigating usage behavior and reading tendency of the public libraries in Seoul.

The purpose of this study is two things. First, it is to develop and demonstrate a sharong taxi platform. To this end, the implications for platform development were derived by analyzing consumers' perceptions of existing taxi services using IPA. As a result, abnormal business activities and safe services in the maintenance area were found to be safe rides and easy rides in the key improvement area. Safety such as usage fee level and driver information provision were derived in the areas subject to improvement, and friendly response and internal and external cleanliness were derived in the areas of excessive investment. The second purpose of this study is to estimate the value given to users for sharing taxi service platforms using the CVM. As a result of estimating the value of the demonstration service of the shared taxi platform developed through this study, the WTP was 3,621 won/per household/per year when expanding throughout Gimhae-si, and 2,515 won/per household/per year. Compared to the willingness to pay for empirical services, only 69.5% of the willingness to pay for the spread project in Gimhae-si. This is the result of a combination of service spread to an unspecified number of people and concerns about service quality due to spatial expansion. This suggests that it is necessary to build data through continuous demonstration and to carefully build a roadmap for spread by upgrading services based on this.

As the national income level is improving, housing urbanization and economic speed are progressing rapidly, household waste and food waste are rapidly increasing. The "Waste Management Act" (founded in 1991) introduced the volume-based household waste system in 1995, and even after implementation, the odor of food waste and the prompt disposal process continue to be a social problem.For this reason, the food waste recycling business is attracting attention. In this paper, regarding the role of resource recycling such as feed, compost, and other resources of food waste, this thesis aims to reduce the inefficiency of the recycling process. Data Envelopment Analysis (DEA) of the relationship between inputs and outputs of 33 facilities nationwide, excluding facility data (insufficient) among 394, (238 public, and 156 private ones), as of the end of 2020, which is running a domestic resource recycling project This study was conducted to investigate the important role in the relative management performance of food waste recycling facilities.It was hypothesized that the influence of business history, facility capacity, capital, and machinery of a company running a food waste recycling business on sales was tested.

The purpose of this study is to evaluate cost side by type of long term care services economically, and then to discuss the findings and implications for the results of analysis. For this research, primary caregivers that provide care the elderly requiring long term care services sanctioned by National Health Insurance Corporation were drawn and surveyed. Among collected data, data for 422 primary caregivers were used for this study. The subjects used in this study consisted of family caregivers from various settings that give care to the elderly. The results of this study can be summarized as follows. First, caregiver's household income level is low. Therefore, caregiving families with the elderly are likely to have financial difficulties. Second, under coverage of long term care insurance system, the direct cost caregiving households pay for the elderly is still very high. Third, indirect cost of caregiving households accounted for the larger proportion caregiving costs. Fourth, social cost burden for caregiving the elderly is very high. This cost amount is appropriately equal to household income of caregivers surveyed in the research. Fifth, service use cost of caregiving households is differentiated by type of long term care service. Sixth, direct cost of caregiving households is statistically significantly differentiated by type of long term care service, but is differentiated less than service use cost. Seventh, social indirect cost for caregiving the elderly is statistically significantly differentiated by type of long term care service. Eighth, social cost amounts for the elderly utilizing long term care service is very high, total social cost per capita by types of long term care service tend to converge on average social cost per capita of total service.

The purpose of this study is to compare the child care time, as well as the perceptions of and satisfaction with the time use, of fathers and mothers in dual-income families with preschool children. 444 time use data were gathered from the Statistics Korea Life Time Surveys in 2019. The results of this study are as follows. First, the total child care time of the two parents per family on a working day was 72.1 min on average, and more time was spent on primary care than on developmental care. Second, the father's child care time on a working day was 40.8 min on average, and the mother's time, almost three times more-110.3 min, which show a significant difference. By type of care, the mother's care time was about three times more than that of father for primary care, and about two times more for developmental care. Third, the mother's primary care time differed by household income level, and the primary care time of both fathers and mothers differed according to the number of their working hours weekly. Fourth, both fathers and mothers felt somewhat tired and had a time deficit, but mothers were less satisfied than fathers with the division of household tasks between them. To encourage fathers' voluntary participation in child care, they must be informed of their joint responsibility with their spouse as parents must be emphasized under the term "co-parenting." It is necessary to expand systems that support parental care and promote a family-friendly culture in workplaces to guarantee the rights of parents.
