Objectives: Busan is reported to have the highest mortality rate among 16 provinces in Korea, as well as considerable health inequality across its districts. This study sought to examine overall and cause-specific mortality and deprivation at the town level in Busan, thereby identifying towns and causes of deaths to be targeted for improving overall health and alleviating health inequality. Methods: Standardized mortality ratios (SMRs) for all-cause and four specific leading causes of death were calculated at the town level in Busan for the years 2005 through 2008. To construct a deprivation index, principal components and factor analysis were adopted, using 10% sample data from the 2005 census. Geographic information system (GIS)mapping techniques were applied to compare spatial distributions between the deprivation index and SMRs. We fitted the Gaussian conditional autoregressive model (CAR) to estimate the relative risks of mortality by deprivation level,controlling for both the heterogeneity effect and spatial autocorrelation. Results: The SMRs of towns in Busan averaged 100.3, ranging from 70.7 to 139.8. In old inner cities and towns reclaimed for replaced households, the deprivation index and SMRs were relatively high. CAR modeling showed that gaps in SMRs for heart disease, cerebrovascular disease, and physical injury were particularly high. Conclusions: Our findings indicate that more deprived towns are likely to have higher mortality, in particular from cardiovascular disease and physical injury. To improve overall health status and address health inequality, such deprived towns should be targeted.

The purposes of this study were to (a) examine disparity in perceived poor health status among people with and without disability, (b) compare the impact of factors, especially income level, on the perceived health status, and (c) determine the impact of disability status on perceived health by income level. The 2014 national survey for the people with disability and the 2013 Korea national health and nutrition examination survey were used to examine the impact of predictors on perceived poor health. logistic regression models were used to estimate the odds ratio of perceived poor health. Among people with disability, 53.7% reported poor self-rated health. People with disability were 3.76 times more likely to report perceived poor health status. The OR of perceived poor health among people with disability was higher in people with severe disability, including brain injury, renal failure, and physical disability. The impact of disability was greater in people with lower income levels. To improve the health status of persons with disability, policies are needed to reduce health disparities among socioeconomic levels. 본 연구는 장애인과 비장애인간의 건강수준에 미치는 요인을 파악하고 특히 장애요인(장애 유무, 정도, 유형)이 미치는 영향과 소득수준에 따른 장애요인의 영향을 살펴보고자 수행되었다. 이를 위해 2014년 장애인실태조사와 2013년 국민건강영양조사 원자료 11,566건을 활용하여 장애인과 비장애인의 주관적 불건강 수준을 산출하였으며, 가중치를 적용한 복합 자료를 위한 로지스틱 회귀분석을 활용하여 장애요인이 주관적 불건강에 미치는 영향을 살펴보았다. 더불어 소득수준에 따라 장애요인이 미치는 영향을 확인하였다. 장애인의 주관적 불건강 수준은 53.7%(95% CI 52.2-55.2%)로 비장애인 14.0%(95% CI 13.0-15.0%)보다 3.8배 높았다. 일반적 요인을 보정한 후 장애인이 비장애인에 비해 주관적으로 불건강할 가능성은 3.76배(OR=3.76) 높았으며, 특히 중증장애를 가진 경우 5.58배 높았다. 장애유형별 영향은 뇌병변장애를 가지고 있는 경우 가장 컸으며(OR=11.17), 다음으로 신장 장애(OR=6.27), 지체 장애(OR=3.63) 및 정신 장애(OR=3.60) 등의 순이었다. 소득수준별로 장애유무의 영향을 살펴보았을 때, 소득수준이 높은 집단에 속한 경우 보다 소득수준이 낮은 집단에 속한 경우에 영향이 더 컸다. 연구결과를 바탕으로 볼 때, 장애인의 사회경제적 수준을 높이는 정책이 필요하다.

Background: Listeriosis caused by Listeria monocytogenes has a high case-fatality rate (CFR) of approximately 20% to 30%. An increasing incidence of listeriosis has been reported in many countries recently. We investigated the annual incidence, clinical characteristics, and outcomes of listeriosis at three different hospitals in Korea and evaluated the effects of appropriate empiric antimicrobial treatments on patient outcomes.

This study was conducted in the hope that controlling the intensity of the ERV air volume will help improve the indoor air quality when applying indoor ventilation through the automatic system of the ERV (Energy Recovery Ventilator) among the ventilation systems. As an experimental method of this study, ERV, cooking facilities, and IAQ (Indoor Air Quality) sensors were installed in the laboratory, and the number of residents was limited to one. In the experiment, the aspect of fine dust was the most noticeable based on baking dishes. Through the experimental data, it was analyzed whether the air volume of ERV and the IAQ value were correlated.
