Purpose: This study aimed to determine the incidence, etiology, prognostic factors, and outcome of acute respiratory distress syndrome (ARDS) in children and to provide epidemiological data of children with ARDS treated at the pediatric intensive care unit (PICU) of a single center in Korea. Methods: We conducted a retrospective medical chart review of 19 children diagnosed with ARDS at the PICU of The Catholic University of Korea, Seoul St. Mary``s Hospital, between March 2009 and February 2012. Results: Of the 334 PICU patients, 19 (5.6%) satisfied the American-European Consensus Conference definition of ARDS. Thirteen patients with ARDS died (mortality rate, 68.4%). Pneumonia was the most common cause of ARDS and observed in 10 patients (52.6%). There were significant differences between survivors and nonsurvivors in the PaO2/FiO2 ratio and the number of organ failure. The mortality rate was significantly higher in patients with a baseline PaO2/FiO2 ratio ≤100 mmHg than in those with a baseline PaO2/FiO2 ratio>100 mmHg (84.6% vs. 33.3%, P=0.046). We observed that a higher number of organ failure during the PICU stay, resulted in a higher mortality rate (P=0.037). Multiple logistic regression analysis showed that the PaO2/FiO2 ratio (adjusted odds ratio, 0.958) was independently associated with the increased risk of death after controlling for the number of organ failure. Conclusion: The mortality rate of ARDS in children was 68.4% in this study, a higher rate than those reported in other national and international studies. The PaO2/FiO2 ratio at the time of ARDS onset was a helpful prognostic factor for predicting the mortality rate of children with ARDS.

Solubility profiles of zein and carotenoid in aqueous ethanol were studied. Zein showed minimum turbidity at the aqueous ethanol concentration of 87 -92%, indicating least aggregations between protein molecules. Solubilitiesof zein and carotenoid increased linearly with the content of yellow zein up to 20% in the aqueous ethanol range of 60-95% tested. At room temperature of 20°C, zein showed maximum solubility in broad ethanol concentration ranges of 60-95%, while that for carotenoid was somewhat narrower with ethanol concentration range of 85-95%. However, at incubation temperature of -20°C, solubilities of both carotenoid and zein were lowered, with dramatic reduction being exhibited at aqueous ethanol concentration of 60% for both compounds, while substantial reduction in solubility was shown at 95% ethanol by zein only. Zein was practically insoluble in absolute ethanol, regardless of temperature range tested, while carotenoid remained largely soluble, though there was pronounced decrease in solubility at the subfreezing temperature.

본 연구에서 개발한 시스템은 기존에 사용되던 유수분리기를 유류가 혼입되어 발생하는 도로, 교량 등의 도시 불투수면 비점 오염저감장치로 업그레이드한 것으로서 유적입자가 coalescence 원리에 의하여 고밀도 고분자 폴리에틸렌 소재를 사용하여 제작된 메디아의 표면과 공간 사이를 타고 이동하면서 합체되어 유적의 크기가 증가한 후 부상하여 제거되는 기전과 SS 성분의 고형물이 침전에 의해 제거되는 원리를 이용한 도시 비점오염저감시설이다. 따라서 본 연구에서는 coalescence 기전을 통해 유수분리가 일어나는 나선형 고분자 여재의 유수분리 특성을 image analysis를 통해 규명하였으며 또한 도로노면 먼지와 폐엔진오일을 이용하여 비점 오염원 저감시설에 유입되는 폐수를 모사하여 비점오염원 저감시설의 유수분리 성능을 실험하였다. 연구에 사용된 여재는 부정형의 투명한 나선형 구조를 갖고 있으며, SEM 사진 및 BET 측정 결과 매끄러운 표면 특성을 나타내고 있다. 직접 측정 방법으로 여재의 표면적을 측정한 결과, 여재 1립당 표면적은 1,428 mm2으로 나타났으며, 단위당 중량은 45.3 kg/m3으로 조사되었다. 또한 폐수 내 기름 입자의 액적크기를 현미경으로 촬영하여 이미지 분석을 수행한 결과, 메디아를 통한 폐수내 기름성분의 제거가 coalescence에 의해 일어나고 있음을 증명하였다. 마지막으로 나선형 부유 메디아를 적용한 비점오염저감시설의 성능평가 결과, 유량에 따라서 부유성 고형물은 86.6∼95.2%, COD(Cr) 87.3∼95.4%, n-Hexane 추출물 71.8∼94.8%의 제거효율을 나타내어 본 장치의 처리성능은 기존의 비점오염원 저감시설의 처리대상물질인 유기물과 부유물질 뿐만 아니라 유류의 제거에도 효과적인 것으로 평가되었다. Non-point source control system which had been designed only for oil-water separation in the fields of oil refinery and garage was upgraded in this research for the removal of runoff pollutants in impervious urban area. Pollutants including oil from driveway and bridge were eliminated by two types of pathway in the system. One is the coalescence mechanism that the oil droplets in the runoff come into contact with each other in the spiral buoyant media surface and form larger coalesced droplets of oil that are carried upstream to the oil layer. The other is the precipitation that solids in runoff were settled by gravity in the system. In this research, coalescing characteristics of oil and water separation were investigated through image analyses, and efficiencies of the non-point source control system were evaluated using dust in driveway and waste engine oil. Media made of high density and high molecular weight polyethylene was indeterminate helical shape and had sleek surface by analysing SEM photographs and BET. Surface area and specific gravity of media which were measured directly were 1,428 mm2 and 45.3 kg/m3 respectively. From the image analyses of the oil droplets photographs which were taken by using microscope, it was proved clearly that the coalescence was the main pathway in the removal of oil from the runoff. Finally, the performances of the non-point source control system filled up with the media were suspended solid 86.6∼95.2%, COD(Cr) 87.3∼95.4%, n-Hexane extractable materials 71.8∼94.8% respectively.

This research was conducted to evaluate quality changes in traditional Doenjang and manufactured Doenjang during a storage period of 8 weeks. Low-salt Doenjang and commercial Doenjang were purchased from different manufacturers and proximate analysis as well as changes in isoflavone, polyphenol, flavonoid contents of the samples were investigated using a mass spectrophotometer. The salinity of traditional Doenjang, low salt Doenjang, and commercial Doenjang were $13.2{\pm}1.15$, $7.17{\pm}2.74$, $10.67{\pm}0.35%$, respectively and the salt concentrations of the soybean pastes did not change during storage. After 8 weeks at $35^{\circ}C$, chromatic values of all the paste samples decreased somewhat, with traditional Doenjang exhibiting fewer changes as compared to manufactured Doenjang. Amino acid nitrogen, acidity, microbial population all tended to increase with time, although some samples showed fluctuations during the test period. Moreover, the total isoflavone contents of traditional Doenjang increased with storage time while that of manufactured Doenjang tended to decrease. The isoflavone aglycone was shown to be the highest in traditional Doenjang, while isoflavone glycoside was abundant in manufactured Doenjang. Total flavonoid contents showed similar trends regardless of samples; initial contents of total flavonoid was 0.6 mg/g which increased to more than twice to 1.4 mg/g at the end of storage period. Composition profile of Doenjang extracts was analyzed using UPLC-Q-ToF.

Purpose : In the treatment of MRSA infection, rapid detection of MRSA is extremely important. The mecA gene codes the new drug resistant polypeptides called PBP2' which mediates the clinically relevant resistance to all beta-lactam antibiotics. The identical mecA gene has been found in coagulase-negative staphylococcus with the methicillin-resistant phenotype. On the other hand, the femA gene was absent from coagulase negative staphylococcus strains with the methicillin resistant phenotype. This study is aimed at early detection and definite diagnosis of MRSA. Methods : A total of 24 MRSA strains were studied. All strains were tested for antimicrobial susceptibility and purified DNA. We amplified both mecA and femA genes by PCR in 24 strains. Results : In MRSA all the 16 strains (100%) carried femA gene and 11 strains (68.7%) carried mecA gene. In contrast, in methicillin sensitive staphylococcus all the 8 strains (100%) carried femA and only 3 strains (37.5%) were detected mecA. Conclusions : As results, there are difference in the phenotype and genotype of methicillin resistance by PCR of mecA and femA. Such disparities between methicillin resistance and the presence of mecA gene suggest the presence of control gene of the mecA.
