Patients treated with peritoneal dialysis have increased intra-abdominal pressure and a high prevalence of abdominal wall complications. Hernias can lead to significant morbidity in patients on peritoneal dialysis. Hernias are clinically important because of the risk of incarceration, strangulation and subsequent bowel obstruction, rupture, and peritonitis. In this paper, a case of incarcerated umbilical hernia with small bowel obstruction in a continuous ambulatory peritoneal dialysis (CAPD) patient is reported. The small bowel obstruction improved after herniorrhaphy, and the peritoneal dialysis was resumed 2 weeks after the herniorrhaphy. The patient had been undergoing CAPD without technical failure until the 2 months follow-up after the herniorrhaphy. This case shows that early detection of incarcerated umbilical hernia and herniorrhaphy can prevent resection of a strangulated small bowel so that it can remain on CAPD without post-operative technical failure. Umbilical hernias should be carefully observed and intestinal obstruction should be considered when a CAPD patient with an umbilical hernia has abdominal pain.

Objectives : This study evaluates the hair growth promoting effect of Yonnyuniksoogobon-dan on shaved C57BL6 mice. Methods : Yonnyuniksoogobon-dan was administered orally (Group I) and both orally and by skin application (Group II) once a day for 12 days. The experimental groups were compared to Control, which was orally administered physiological saline solution. Hair regrowth was photographically and histologically determined during the experimental period. The levels of hair growth cycle related factors (EGF, TGF-${\beta}$1) and vascular factors (VEGF, iNOS) were also determined by immunohistochemistry. On gross observation of hair growth, both Group I and Group II shaved C57BL6 mice showed accelerated hair regrowth. Results : The hair regrowth index of Group I increased significantly from 7 days (P<0.05) to 12 days (P<0.01) after shaving and that of Group II was significantly higher at 12 days (P<0.05). On histological observation, both Group I and Group II demonstrated histological improvement and increases in the number and diameter of the hair follicles. EGF expression on the root sheath of hair follicles was up-regulated in both Group I and II. TGF-${\beta}$1 expression on the root sheath of hair follicles was unchanged in both Group I and II. VEGF expression in the tissues surrounding hair follicles was up-regulated in both groups. iNOS expression in the tissues surrounding hair follicles was down-regulated in both groups. Conclusions : These results suggest that Yonnyuniksoogobon-dan promotes hair growth and this effect is related to up-regulation of EGF and VEFG expression and down-regulation of TGF-${\beta}$1 and iNOS expression on hair roots.

For the longevity of OLEDs, passivation of OLEDs is an important process step since organic materials used in OLEDs are very vulnerable to moisture. In this work, the passivation effect of the plasma polymerized para-xylene (PP$\rho$X) layers was studied. The PPpX layers deposited by PECVD were formed on top of the cathode with various plasma powers of 50 - 90 W. Passivation effect of PP$\rho$X was significantly dependent upon the deposition plasma power of the PP$\rho$X film. The lifetime of OLEDs with the 70 W deposited PP$\rho$X passivation layer was about 5 times longer than that of the control device.

Objective£ºThe purpose of this study is to describe the commom complications of craniofacial approaches to lesion on anterior skull base and some technical refinements to prevent the complications. Methods£ºAuthors reviewed medical records and radiological findings of 21 operations(including 2 reoperations) of 19 patients having anterior skull base tumors treated by craniofacial approaches from 1998 to 2004 . Results£ºTwenty-one operations showed several complications. Those were cerebrospinal fluid leakage(3), meningitis(1), anosmia(3), epidural hematoma(1), pneumocephalus(1). Cerebrospinal fluid leakage was treated by lumbar drainage. Meningitis was treated by lumbar drainage and appropriate antibiotics. Epidural hematoma and pneumocephalus were resolved spontaneously. The complication of transfrontal and transnasomaxillary approach was none. The complications of transfrontal nasal approach were anosmia(1) and epidural hematoma(1). Cerebrospinal fluid leakage(3), meningitis(1), anosmia(2), and pneumocephalus(1) arose in the transfrontal nasal-orbital approach. Conclusion£ºMotality and morbidity of craniofacial approach is relative low. Water-tight duroplasty, strong reconstrucion of anterior skull base and lumbar drainage are important for prevention of cerebrospinal leakage. We think that the lesion of anterior skull base is safely performed by appropriate craniofacial approach and reconstruction.

To invastigate the epidemiological trait of listeriosis, Listeria monocytogenes were isolated from the carcasses of pigs and cattle, and environmental specimens in slaughter house. Also serotype of isolates were classified by rapid slide agglutination test. In the carcasses of pigs, Listeria sp were isolated from the carcasses after bleeding(62%), after dismemberment(60.0%) and before shipping(76.0%), and L monocytogenes were present in 8% of the carcasses after dismemberment and in 14% of the carcasses before shipping. However, few Listeria sp were isolated from the living body skin and the carcasses after scalding. In the carcasses of cattle, Listeria sp were isolated from the carcasses after bleeding(10%), after dismemberment(36.7%) and before shipping(63.3%), L monocytogenes were present in 3.3% of the carcasses after dismemberment and in 10% of the carcasses before shipping. Overall, L monocytogenes, L innocua, L welshimeri, L grayi, and L murrayi were present in 4.8, 40, 2.3, 2.6 and 0.3% of all the carcasses, respectively. Prevalence of Listeria sp in environmental specimens were found to be 80% in slaughter house floors and 100% in sewage, and L monocytogenes were present in 15% of sewage. However, few Listeria sp were isolated from chilled water and from scalding water. Overall, L monocytoge-nes, L innocua, and L welshimeri were present in 3.8, 45 and 6.3% of all the environmental speci-mens, respectively. A total 27 strains of L monocytogenes were isolated from samples tested and all of the strains were classified into serotype 1.

전통적인 BI(Business Intelligence) 시스템은 제 시간에 더 나은 의사결정을 위한 도구로 널리 사용되어 왔다. 그러나 급증하는 데이터에 대한 효율적 분석을 위해 데이터 웨어하우스를 구축하는 일은 시간이 오래 걸리고 복잡하다. 특히, 데이터 웨어하우스 구축에 요구되는 ETL(Extract, Transform, Load) 프로세스는 BI 플랫폼이 클라우드 환경으로 전환되면서 훨씬 더 복잡해졌다. 이러한 ETL 이슈를 극복하기 위해 MongoDB와 같은 NoSQL 데이터베이스에 기반한 다양한 BI 솔루션들이 제안되었다. 한편, 의사 결정권자는 IT 부서나 BI 전문가의 도움 없이 데이터에 쉽게 접근할 수 있기를 원한다. 최근, 이러한 BI 이슈들을 해결하기 위한 방안으로 셀프서비스 BI가 등장하였다. 본 논문에서는 귀농귀촌인의 재배 작물 선택을 지원하기 위해 MongoDB 클라우드를 데이터 웨어하우스로 하는 농업 데이터 기반의 셀프서비스 BI 시스템을 제안한다. 제안 시스템은 의사 결정권자에게 통찰력을 제공하기 위해 MongoDB 차트를 이용한 데이터 시각화 기능, 고급 데이터 검색을 위한 리포팅 기능, 실시간 데이터 분석을 위한 모니터링 기능을 지원한다. 의사결정권자는 다양한 방식으로 데이터에 직접 접근할 수 있고, 제안 시스템의 기능들을 활용하여 셀프서비스 방식으로 데이터를 분석할 수 있다. Traditional business intelligence (BI) systems have been used widely as tools for better decision-making on time. On the other hand, building a data warehouse (DW) for the efficient analysis of rapidly growing data is time-consuming and complex. In particular, the ETL (Extract, Transform, and Load) process required to build a data warehouse has become much more complex as the BI platform moves to a cloud environment. Various BI solutions based on the NoSQL database, such as MongoDB, have been proposed to overcome these ETL issues. Decision-makers want easy access to data without the help of IT departments or BI experts. Recently, self-service BI (SSBI) has emerged as a way to solve these BI issues. This paper proposes a self-service BI system with farming data using the MongoDB cloud as DW to support the selection of new crops by return-farmers. The proposed system includes functions to provide insights to decision-makers, including data visualization using MongoDB charts, reporting for advanced data search, and monitoring for real-time data analysis. Decision makers can access data directly in various ways and can analyze data in a self-service method using the functions of the proposed system.
