최근 코로나19 팬데믹의 영향으로 온라인 소비가 늘면서 종이, 플라스틱 등 재활용품의 사용량이 증가하고 있다. 또한 1인 가구의 중가에 따라 분리수거 배출이 제대로 이루어지지 않는 추세이다. 대부분의 1인 가구가 거주하고 있는 원룸 밀집 지역의 분리수거 여건이 제대로 갖춰진 곳이 많지 않으며, 분리수거 기준이 모호한 종류들이 많다. 재활용품 분리수거가 제대로 이루어지지 않는다면 에너지 및 자원낭비와 쓰레기 소각으로 인한 환경오염이 초래된다. 본 논문에서는 딥러닝 객체 인식 및 검출을 통한 재활용품 분류 결과에 따른 모터제어 및 분리수거를 진행하는 재활용품 분리수거 장치를 개발하였다. 해당 장치는 객체인식 알고리즘 YOLOV4를 이용하여 객체를 인식 및 검출한 후 모터제어, LED를 통해 분리수거 및 피드백을 제공한다. 이를 활용하여 누구나 쉽게 분리수거를 할 수 있도록 편의성을 제공하며 재활용 쓰레기 수거율을 높여 소각으로 인한 환경오염 방지를 기대할 수 있다.

Dental sealant is a procedure to prevent dental caries on the occlusal surface of healthy teeth. Raw data from the 6th-7th Korean National Health and Nutritional Examination Survey (KNHANES) were analyzed. This study was conducted to provide basic data which is necessary for the national health care project and for expanding the standards of coverage for the Dental sealant procedure. In this study, subjects were a total of 4,366 children from the age of 6 to 18 and surveyed for the Amount of Received Dental sealant and rate of Received Dental sealant. In 2012, the coverage rate for pit and fissure sealing procedures differed significantly in terms of age, residential area and average monthly income. This coverage varied as per average monthly income in 2014 and as per age and average monthly income in 2017 (P < 0.05). In 2014, average monthly income had a significant influence on the coverage rate, while age and average monthly income had a significant influence on it in 2017 (P < 0.05). These findings suggest that in order to increase the sealing procedure coverage, continuous promotion of dental sealant projects, reduction of copayments, inclusion of varied tooth types and age groups, expansion of coverage to isolated areas and inclusion of socially disadvantaged groups are necessary.

As the basic old-age pension system was enforced in 2008, the base for old-age income security was founded. However, due to the basic old-age pension played a minor role as assistant allowance, it did not reach to sufficient level to cover full income security system. It is estimated that the dependency on private transfer income among the elderly who are difficult to be economically independent is still high. Therefore the poverty rate of the elderly households, who are not economically active or who are not protected by old-age income security system, is more likely to be higher than that of non-elderly households. Based on the assumption that public transfer income system should become a central means of old-age life guarantee, this study examined the poverty mitigation effects among the elderly households by comparing the private transfer income and the public transfer income. For this purpose, we selected single-elderly-households who have been considered the most vulnerable to poverty. We used 2006- 2008 Household Income and Expenditure Survey dataset that contained single-elderly who were older than 65 years old. To understand the conditions of poverty among single-elderly-households and the degree of poverty-reducing effect originated from income transfer system, we compared the poverty rates of total households and the whole elderly households. Next, we analysed the poverty of the single-elderly-households by social demographic factors such as gender, age, and economic activity. Our major findings are as follows: First, the poverty rate of the whole elderly households were not reduced, even though the basic old-age pension and long-term care management system were enforced in 2008. Second, half of the elderly households including single-elderly-households belonged to the absolute poverty line. Relatively higher level of poverty among the single-elderly-households was found especially those who were female, unemployed, low-educated, older, and rural single-elderly-households. Third, the effect of the public transfer income on mitigating the single-elderly-households poverty showed a little progress. However, even greater poverty reducing effect was found by the private transfer income system. Fourth, in a group of the public transfer systems, the public assistance such as supporting living costs contributed more to reduce poverty of the elderly population than the public pension system did.

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.

Environmental education is the most important and fundamental way to deal with the climate change. The school policy concentrating on environmental education, which has been established and financially supported by the Korea Ministry of Environment, provides an environment for natural experiment, examining the effect of reinforcing environmental education at schools on the energy-saving behaviours observed in the households concerned. We investigated the impact by applying the difference-in-difference measure to various utilities including water, electricity and gas between the households with children whose schools were designated as pilot environmental education schools in 2011 and the households with children attending general schools. The results showed that the households with children attending the pilot environmental education schools paid lower electricity and gas costs. This implies that environmental education provided at schools can indirectly affect the household energy saving behaviour and in turn reduce the total energy consumption in a short time.

This study was conducted on 2,380 people aged 40-64 years old among the subjects of the National Health and Nutrition Examination Survey in 2021, the 3rd year of the 8th period. In order to identify factors influencing disease morbidity and health-related quality of life according to household type, general characteristics, diseases, etc. Morbidity and physical factors were compared and analyzed. The data were analyzed after creating a weighted complex sample plan file using the spss 25.0 program, and the significance level was set at .05. As a result of the analysis, factors affecting single-person households were education level, restrictions of activity, and depression, and factors affecting multi-person households were gender, smoking, restrictions of activity, dyslipidemia, and depression. Subjective health status showed a positive correlation with health-related quality of life, and anxiety and stress showed a negative correlation. Based on the results of this study, It is that propose individual quality-of-life improvement interventions that take into account each influencing factor for each household type.
