In South Korea, scrub typhus is the most common acute febrile illness in autumn. We analyzed scrub typhus cases reported from 2008 to 2012 to describe the epidemiology of scrub typhus as well as eschar patterns. A total of 30,478 cases were reported from 2008 to 2012; the incidence rates were higher in the southern and western regions of South Korea. The common clinical symptoms of confirmed scrub typhus cases from 2010 to 2012 were fever/chills (95.2%), eschars (78.9%), and myalgia (61.7%). The

OBJECTIVE: This study examined how knowledge, risk perception, health beliefs and multidimensional health locus of control (HLC) were associated with caregivers' intention to vaccinate their child, and how these associations varied across child age groups. SETTING: South Korea. METHODS: The cross-sectional survey was conducted via a face-to-face interview among 1017 nationally representative caregivers who had children aged 12 or younger. The outcome variable was caregivers' intention to vaccina

Since its recent introduction to the filtration industry, one of the major concerns about the use of fiber in water treatment has been its applicability for high-rate filtration while minimizing the build-up of headloss. In this study, a compact, modular filter employing non-woven, highly porous polypropylene fiber as filter media was investigated for the treatment of turbid water under high filtration rates. The impact of different operating variables such as polyaluminum chloride (PAC) dose an

Saliou (Eur J Epidemiol, 1994, 10 (4), 515–517) argued that pandemics are special kinds of crises and requires the public health sector to focus on: 1) reducing uncertainty, 2) rumor mitigation, and 3) ensuring the public reduces their risk of contracting the disease. With this as a backdrop, the central aim of this research is to better understand the connections between public information seeking, evaluation, and self-protective behaviors in the COVID-19 pandemic and focuses on a comparison be

Preceding infection or inflammation such as bacterial meningitis has been associated with poor outcomes after stroke. Previously, we reported that intracorpus callosum microinjection of lipopolysaccharides (LPS) strongly accelerated the ischemia/reperfusionevoked brain tissue damage via recruiting inflammatory cells into the ischemic lesion. Simvastatin, 3-hydroxy-3-methylgultaryl (HMG)-CoA reductase inhibitor, has been shown to reduce inflammatory responses in vascular diseases. Thus, we invest

This study was carried out to identify the filter performance of fibre filter module treating high-turbidity water at extremely high filtration rates (1000-2500 m/day). The effects of filter aid chemical (polyaluminium chloride (PAC)), filtration rate and particles size on filter performance were investigated. It was found that PAC was a crucial factor influencing the separation process. Even though the optimum PAC dose for the raw water with turbidity of 50 nephelometric turbidity units (NTU) w

이 연구는 여러 항생제에 내성을 지닌 다제내성균에 대해 미디어가 어떻게 보도하는지를 알아보기 위해, 기사 제목에 나타난 핵심어를 언어 네크워크 분석을 이용하여 살펴보았다. 이를 위해 한국언론진흥재단의 기사검색사이트인 카인즈(www.kinds.or.kr)와 언론사의 홈페이지를 통해 약 28개 언론사를 대상으로 2010년 6월 1일부터 2011년 12월 31일까지 229개의 다제내성균 관련 기사를 분석하였다. 먼저, 뉴스 제목에 나타난 핵심어를 분석한 결과, 기사 제목에서 '슈퍼박테리아'(155건)가 가장 많이 사용된 것으로 나타났으며, 불안감을 촉발시키는 '감염'(63건) 용어도 많은 것으로 나타났다. 신종 감염병 보도의 전체 네트워크 구조는 '국내', '다제내성균', '첫', '항생제', '슈퍼박테리아', '발생', '감염' 등의 핵심어를 중심으로 형성된 반면, '관련주', '의료진', '안전' 등은 네크워크 중심에서 크게 벗어나 있었다. The present study perfor

This study was conducted to develop a vertical subsurface flow (VSF) wetland remediation system packed with woodchips to control stormwater pollution arising from livestock agriculture. Three lab-scale VSF wetlands were operated with recirculation during the interval (Δ) between storms as 2, 4 and 8 days, respectively. The fed water was 100% recirculated one time per 24 h; the recirculation frequency was 1, 3 and 7 times at Δ of 2, 4 and 8 days, respectively. The constructed wetland systems prov

가축사육지역으로부터 발생되는 강우유출수 처리를 위해 건설된 인공습지에 대해 2010년 5월부터 2011년 11월까지 수행한 20회의 강우시 모니터링을 통하여 얻은 자료를 분석한 결과 강우시 저감효율은 TSS 88%, BOD 54%, <TEX>$COD_{Mn}$</TEX> 35%, <TEX>$COD_{Cr}$</TEX> 70%, TN 31%, TP 64%이었다. 이론적으로 강우계급의 증가(강우유출량 증가)는 습지의 수리학적 교환비율을 증가시키기 때문에 TSS 저감효율은 감소해야하는데 교환비율이 1에 접근하였을 때 대략 55%의 효율을 달성하였다. 또한 연속적인 강우활동, 개별적인 강우사상의 대소, 강도, 선행건기 일수 등 습지에서는 실험자가 제어할 수 없는 수많은 자연변수들이 복합적으로 작용하기 때문에 처리효율의 변동이 매우 컸다. 효율에 가장 큰 영향을 미친 요인으로는 수리학적 요인과 함께 조류증식이 성능 불확실성에 크게 기여하였다. Stormwater wetland targeted

A laboratory study was undertaken to pursue the filter performance of a micro-filter module employing highly porous fibre media under a high filtration rate (≥1,500 m/day), faster than that of any conventional filter process. The effects of filtration rate, head loss, raw water turbidity, and filter aid chemicals on filter performance were analysed. In spite of the extremely high filtration rate, the filter achieved an attractive efficiency, reducing the raw water turbidity by over 80%. As with

Three pilot-scale compact constructed wetland systems were constructed to treat stormwater from a highway. They each comprised a sedimentation tank, and a vertical flow (VF) wetland bed equipped with a recirculation device. The VF wetland beds were filled with woodchip, pumice and volcanic gravel, respectively. According to the analysis of the particle size distributions (0.52-500 μm), the predominant particles in stormwater ranged in size from 0.52-30 μm. In the sedimentation tank, with a 24 h
