Portosystemic shunt (PSS) was diagnosed in 43 dogs by mesenteric portogram from January, 2002 to June 2007 in Haemaru referral animal hospital. PSS was found in various breeds including Maltese, Miniature Schnauzer and Yorkshire Terrier and there was no predisposition in gender. In laboratory parameters, mean cell volume was lower than normal value in single shunt and alanine aminotransferase was higher than normal range in multiple shunts with clinical significance. Cystic calculi were found in over 50% dogs with PSS and even in 70.8% dogs with single shunt. In 81% dogs with PSS, extrahepatic single shunt such as portocarval type and portoazygous type was identified. Extrahepatic multiple shunt and intrahepatic single shunt were observed in 4 dogs, respectively. Gradual attenuation using ameroid constrictor was applied to 35 dogs with extrahepatic single shunt and the prognosis of these dogs were good except two dogs, which showed poor prognosis because of acquired multiple PSS and renal disease unrelated with PSS, respectively.

Gastrointestinal stromal tumor (GIST) is one of the mesenchymal tumors originated from gastrointestinal submucosa. A 10 year-old, male, mixed breed dog with persistent diarrhea, anorexia and lethargy was referred to Haemaru Animal Referral Hospital. Large mass originated from the transverse colon was observed and large amount of ascites and free gas were found on abdominal radiography and ultrasonography. The ascites was septic exudate mixed with bacteria that consisted with intestinal perforation. There was no metastatic lesion. This mass was tentatively diagnosed as adenocarcinoma, leiomyosarcoma (LMS) and lymphosarcoma and surgical resection and histilogical examination were planned. However, according to owner's request, the patient was euthanized and then the necropsy was performed. About 10 cm sized mass originated from the cecum, ascending colon and transverse colon was adhered to surrounding mesentery and the perforation and large amount of ascites were observed. GIST was suspected on histopathologic examination and confirmed according to CD 117 expression in immunohistochemistry. GIST, derived from interstitial cells of Cajal, can be distinguished from LMS and leiomyoma (LM) on the basis of expression of CD117 (KIT) immunohistochemically. GIST has a different biological behavior and clinical course compared with LMS and LM, therefore definite diagnosis for GIST using immunohistochemistry is clinically important to predict the precise prognosis of the patient.

In recent years, Korean government has focused on improving the environmental impact of products in order to reduce greenhouse gas emissions and to achieve their energy goals. The government has been conducting the following polices such as green procurement inducement and certification system. After carbon labeling was conducted in 2009, among a total of 1,065 items, 97 building materials have been given a certification: finishing materials items have the highest weight (56%). The increase in the certification numbers shows that there has been considerable technical efforts in the building material industry. At the awareness of carbon label and purchase of low carbon product, however, customers are aware of carbon labeling but the purchasing rate of carbon product is low. In this paper, we suggest that low carbon activities must also be considered in order to create client value by adding the concept of ecological efficiency. The objective of this study to measurer the eco-efficiency of carbon labeled building materials on the basis of environmental aspects of the product with the perspective of economy for purchasing the excellent products.

Caudal occipital malformation syndrome (COMS) is relatively common disease which occurs at craniocervical junction. It has been known that this syndrome was developed mainly in Cavalier King Charles spaniels, but these days there are a lot of case reports about COMS in other small breed dogs. In this report, COMS was diagnosed in ten dogs presented to Haemaru Referral Animal Hospital using MRI examination from January 2005 to April 2006. These cases were also investigated about concurrent diseases and syringomyelia was the most common type of complication, but clinical signs were nonspecific. COMS could be controlled by medical therapy with corticosteroid except cases with concurrent meningitis. It is considered that the present report could provide information regarding imaging and clinical features of COMS such as concurrent diseases, clinical signs, and prognosis in small animal practice despite of limited case numbers.

Isolated splenic torsion is a rare disease, which is usually produced in deep-chest large breed dogs. A five-year old Pitbull terrier and a four-year old Yorkshire terrier were diagnosed as isolated splenic torsion with chronic form. Leukocytosis, anemia and elevated hepatic enzyme level were found in blood test and a large amount of ascites was observed. Abdominal radiography revealed splenomegaly and ascites and ultrasonography showed diffuse hypoechoic change of spleen in case 1 and hyperechoic change of spleen with focal hypoechoic regions in case 2, thromboembolism of splenic vein and abnormal direction of spleen. To identify the underlying disease of isolated splenic torsion, the histopathologic examination of excised spleen is essential and splenic neoplasia was found in case 2. Chronic isolated splenic torsion shows nonspecific clinical signs and laboratory results. Through diagnostic procedure, particularly ultrasonography, prompt diagnosis may be achieved and improve the prognosis of the patient.

Public library users' perception of librarians can be an important aspect in improving the public library uses and the quality of informn services. Thus it is necessary to identify what factors affect users' perceptions of librarians. This research empirically investigated users' general perceptions of librarians and the factors affecting them through a survey. As a result, it was found that the use of library collections, library facilities, and participation in club activities through the library affect the formation of a positive perception of librarians. In addition, the roles of the librarian are expanding from informational activities to supporting social activities. In contrast, the factors of direct interaction with the librarian, including participation in public library programs, circulating library collections, and communication with librarian, do not have a significant effect on the formation of the perception of librarian. Thus librarians need to consider library users more substantially and to support them in various ways. 공공도서관의 이용 및 정보서비스의 질을 제고하는데 있어 이용자들의 사서에 대한 인식이 중요한 측면이 될 수 있으며, 따라서 이용자들의 사서에 대한 인식에 영향을 미치는 요인들이 무엇인지에 대한 확인이 필요하다. 이에 본 연구에서는 공공도서관을 중심으로 이용자들의 사서에 대한 일반적인 인식 및 이에 영향을 미치는 요인을 설문조사를 통해 실증적으로 확인하였다. 분석 결과, 도서관 소장자료와 설비의 이용, 도서관을 통한 동아리 활동 참여는 사서에 대한 긍정적인 인식 형성에 영향을 미치고 있으며, 사서의 역할은 정보적 활동에서 사회적 활동을 지원해 주는 방향으로 확대되는 것으로 나타났다. 반면 공공도서관 프로그램 참여나 소장자료의 대출, 사서와의 커뮤니케이션 등 사서와의 직접적인 교류가 이루어지는 요인들이 사서에 대한 인식 형성에 유의미한 영향을 미치지 않고 있으며, 따라서 사서의 이용자에 대한 고려가 보다 실제적으로 반영될 필요가 있는 것으로 나타났다.

부동산 투기근절, 공평과세 목적으로 부동산 실거래 신고제도가 도입된 이후, 정부에서 운영 중인 부동산거래관리시스템에는 연간 약 200만 건의 부동산 실거래 신고자료가 축적되고 있다. 인터넷이 발달하고 정보에 대한 접근성이 높아진 요즘, 부동산 투자에 대한 관심 증가로 부동산 가격정보에 대한 요구도 나날이 증가하고 있다. 하지만 이는 단순히 거래사례에 대한 정보만을 제공할 뿐이라 공동주택 실거래의 경우 동, 호수, 토지건물 실거래의 경우 지번을 개인정보보호 등의 이유로 공개하고 있지 않아 실거래의 위치별 정확한 데이터를 구득하기 어려운 실정이어서 정보의 비대칭성이 여전히 존재하고 이러한 부동산 정보의 특수성이 부동산시장에서의 투기가 근절되지 않는 이유 중 하나이다. 본 논문에서는 축적된 실거래 신고가격 데이터를 활용하여 실거래 미발생 지점에 대한 시세가격 추정 모형을 도출하는 것으로, 부동산 가격이 지리적 위치에 따라 결정되는 특수성을 가지는 것을 고려하여 공간구조가 반영될 수 있도록 공간회귀 모형을 통한 추정 토지 시세가격의 정확도를 살펴보았다. Since the real estate reporting system was first introduced, about 2 million real estate transaction per year have been reported over the last 10 years with an increasing demand for real estate price estimates. This study looks at the applicability and superiority of the regression-kriging method to derive effective real transaction prices estimation on the location where information about real transaction is unavailable. Several issues on predicting the real estate price are discussed and illustrated using the real transaction reports of Jinju, Gyeongsangnam-do. Results have been compared with a simple regression model in terms of the mean absolute error and root square error. It turns out that the regression-kriging model provides a more effective estimation of land price compared to the simple regression model. The regression-kriging method adequately reflects the spatial structure of the term that is not explained by other characteristic variables.

The distributed OCSP (Online Certificate Status Protocol), composed of multiple responders, is a model that enhances the utilization of each responder and reduces the response time. In a multi-user distributed environment, load balancing mechanism must be developed for the improvement of the performance of the whole system. Conservative load balancing algorithms often ignore the communication cost of gathering the information of responders. As the number of request is increased, however, fail to consider the communication cost may cause serious problems since the communication time is too large to disregard. We propose an adaptive load balancing algorithm and evaluate the effectiveness by performing modeling and simulation. The principal advantage of new algorithm is in their simplicity: there is no need to maintain and process system state information. We evaluated the quality of load balancing achieved by the new algorithm by comparing the queue size of responders and analyzing the utilization of these responders. The simulation results show how efficiently load balancing is done with the new algorithm.

Mesenteric torsion was diagnosed in a 2-year-old, spayed female Miniature Schnauzer. The patient was presented with acute depression, vomiting, lethargy and hematochezia. On physical examination, severe dehydration, tachycardia, tachypnea, weak femoral pulse, delayed capillary refill time and pale mucous membrane were found and the dog was in shock. Radiography and ultrasonography revealed intestines distended with gas, ascites and the "C" shaped distended intestine. Medical treatments including fluid therapy, analgesics, antibiotics and lidocaine for reducing reperfusion injury were applied. And then, the mesenteric torsion was definitively diagnosed through exploratory laparotomy and intestinal resection and anastomosis were performed. The dog made an uneventful recovery and was free of clinical sign one week after surgery. Mesenteric torsion is an unusual and life-threatening disease in dogs. It has usually been described in the middle and large breed dogs, especially German Shepherds. However, the mesenteric torsion should be included in the differential diagnostic lists for acute abdomen even in small breed dog. The mortality rate of mesenteric torsion can be reduced through prompt diagnosis, proper preventive therapy for shock and reperfusion injury and emergency surgery.
