저자들은 만성 신부전으로 장기간 투석중인 환자에게서 특별한 외상없이 발생한 Aeromonas hydrophila에 의한 괴사근막염이 적절한 항생제 및 외과적 수술로 호전된 일례로 아직 투석과 관련된 A. hydrophila 감염이 국내에 보고된 적이 없기에 문헌고찰과 함께 보고하는 바이다. Aeromonas hydrophila is a facultative, anaerobic gram-negative bacillus. It's a member of the family Vibrionaceae. Aeromonas, which is known to cause gastroenteritis and wound infections ranging from mild cellulitis to fulminant myonecrosis. It is responsible for opportunistic infections in patients with compromised immune function due to an underlying disease such as malignant hematological disorders, liver cirrhosis, and malignant neoplasm. We report a case of 72-year-old woman who recovered from necrotizing fasciitis caused by A. hydrophila. The patient had undergone prolonged hemodialysis and had no history of trauma.

The purpose of this study was to define the effect of Taekwondo gym Master Instructor's Transformational leadership on master's organizational justice and organizational performance and that of master's organizational justice on organizational performance. For the purpose, 300 masters of Taekwondo gyms located in Seoul and Gyeonggi area were selected as population, and total 300 respondents were sampled from the population. Then, 263 sheets were used for actual analysis. Exploratory factor analysis, reliability analysis and multiple regression analysis were applied to the collected data by using SPSS 12.0 program. Following results were extracted. First, Taekwondo gym Master Instructor's Transformational leadership had positive effects on master's organizational justice. Second, Taekwondo gym Master Instructor's Transformational leadership had positive effects on organizational performance. Third, master's organizational justice had positive effects on organizational performance.

V. fluvialis는 해수 및 담수에 서식하는 세균으로서 우리나라나 일본같이 해산물을 많이 섭취하는 나라에서 잘 발생함에도 불구하고 국내에서는 한 예만 보고된 바 있고, 그 환자는 간신증후군으로 사망하였다. 저자들은 지난 8월 해산물 섭취력이 없는 39세 알콜성 간질환 남자 환자의 대변 배양검사에서 V. fluvialis에 의한 위장관염을 확진하였고 급성신부전으로 악화되었으나 치료된 증례를 경험하였기에 이에 보고하는 바이다. Vibrio fluvialis is one of the non-cholera, halophilic, gram-negative bacterium that causes gastroenteritis. There have been a few reports of V. fluvialis infections worldwide. In the present report, one case of gastroenteritis caused by V. fluvialis which occurred in chronic liver disease patient in Korea is presented. This was a rare case of gastroenteritis caused by V. fluvialis in 39-years old man who had no history of seafood ingestion. He was admitted because of severe watery diarrhea and abdominal pain, and developed acute renal failure. The patient was improved after fluid and antibiotic therapy for 2 weeks.

<P>The complementary ZnO-Si nanocomposites were synthesized via facile solution process at room temperature and enhanced photoconductive switching behavior was observed under a white light irradiation. The morphology and atomic/electronic structure of ZnO-Si nanocomposites were investigated by atomic-resolution (scanning) transmission electron microscopy combined with electron energy loss spectroscopy. It is revealed that host ZnO nanorods contained peculiar nm-sized Si-rich phases on the ZnO surface, in which effective band gap was significantly decreased. Our results explain a collaborative interaction between host ZnO nanorods and Si-rich phase which led to an enhancement of photoconductive properties over as-prepared ZnO nanorod.

<P>Urban particulate matter (UPM) exerts negative effects on various human organs. Transient receptor potential vanilloid 1 (TRPV1) is a polymodal sensory transducer that can be activated by multiple noxious stimuli. This study aimed to explore the effects of the UPM 1648a on the expression of TRPV1, and its regulatory mechanisms in HaCaT cells. UPM enhanced TRPV 1 promoter-luciferase reporter activity. UPM also increased expression of the TRPV 1 gene as evidenced by increased mRNA and protein levels of TRPV 1. In addition, elucidation of the underlying mechanism behind the UPM-mediated effects on TRPV 1 expression revealed that UPM can upregulate expression of the TRPV1 gene by activating activator protein-1 (AP-1) and nuclear factor kappa B (NF-κB). The UPM treatment also altered Ca<SUP>2+</SUP> influx and cell proliferation, as well as production of interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β). In addition, these UPM-induced effects were attenuated by SB203580 and ammonium pyrrolidinedithiocarbamate (PDTC). However, SP600125 and PD98059 did not alter the UPM-induced effects. Taken together, these findings indicate that UPM upregulates expression of the TRPV 1 gene, which is mediated by the p38 mitogen-activated protein kinase (MAPK) and NF-κB signaling pathways and suggest that UPM is a potential irritant that can induce skin processes such as aging and inflammatory responses.</P>
