In 3 dogs with gallbladder mucocele, rupture of gallbladder was diagnosed and treated. Althoughthe diagnosis of gallbladder is challenging due to non-specific clinical signs and physical examinationfindings, mucoceles are ultrasonographically characterized by the appearance of the stellate or finely striatedbile paterns and difer from biliary sludge by the absence of gravity dependent bile movement. In thiscase, gallbladder rupture caused by mucocele can be diagnosed based on not only above characteristicsbut secondary lesion such as ascites around gallbladder and swollen hyperechoic mesentery.

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.

Pancreatic pseudocyst is one of the most common pancreatic mass lesions developed following acute or chronic pancreatitis. Two dogs were presented with nonspecific clinical signs such as abdominal pain, vomiting and depression and diagnosed as pancreatic pseudocysts through percutaneous ultrasound-guided aspiration. Pancreatic pseudocyst may contain pancreatic juice, so leads the deteriorate state of patient through pertinent inflammation and autodigestion of pancreas. In this study, the clinical signs and pancreatic lesion were improved after aspiration. Percutaneous ultrasound-guided aspiration can provide the diagnostic information through cytology and lipase and amylase concentration, and be selected as the first choice for treatment.

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.

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.

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.

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.

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.

Background: The risk of imported infectious diseases has been increasing with the annual rise in the number of international travelers. Objectives: This study aims to analyze the distribution and characteristics of intestinal bacteria isolated in 2019 from residents of Chungcheongnam-do Province with experience of travelling overseas. Methods: Twenty-three former overseas travelers with diarrhea were analyzed to detect viruses and bacteria according to the Manual for Detection of Foodborne Pathogens at Outbreaks. Additionally, antibiotic susceptibility tests and 16s rRNA sequencing were performed. Results: Twenty-five strains of ten pathogens were isolated from 18 samples. Pathogenic E. coli was the most common at 57.7%, followed by Clostridium perfringens (15.4%), Campylobacter spp. (7.7%), and Salmonella spp. (7.7%). The serotype of Salmonella was confirmed as Salmonella Braenderup, II 9,46:g,[m],[s],t:[e,n,x]. Conclusions: It was confirmed that the major enteric bacterial pathogens isolated from overseas travelers in Chungcheongnam-do Province were pathogenic E. coli , as found in other studies. The study on Plesiomonas shigelloides is meaningful in that it is reported as a rare case of infection in Korea. Antibiotic resistance and 16s rRNA analysis were performed, which is expected to provide important basic data for the prevention of traveler’s diarrhea.

공간 관계 기억에서의 시각적 주의 : 물체 특성 기억과의 비교 및 개인차

목적 본 연구에서는 성인의 물체 특성 정보 기억과 공간 관계 정보 기억 간 시각적 주의 차이 및 동일 종류의 정보를 기억할 때 시각적 주의의 개인차를 분석하였다. 방법 이를 위해 서울 소재 대학(원)생 32명을 대상으로 물체의 색을 기억하는 과제와 물체 간 공간 관계를 기억하는 과제 수행 중 시선추적을 실시하고 과제 수행 전략에 대한 인터뷰를 진행하였다. 시선고정 및 시선이동 측정치와 참여자가 보고한 과제 수행 전략에서 과제 간, 개인 간 차이가 있는지 비교하였다. 결과 시선추적 결과, 화면 전체 중 물체 영역에 시선을 고정하는 빈도 및 시간의 비율이 물체 특성 과제에서 유의하게 높았고, 시선이동의 거리가 물체 특성 과제에서 유의하게 길게 나타났다. 이러한 차이는 공간 관계 과제의 히트맵에서 물체 영역 사이의 화면 중앙 지점에 시선이 집중되는 패턴과 관련된 것으로 이해할 수 있었다. 참여자가 보고한 과제 수행 전략은 두 과제 모두에서 한 번에 한 물체씩 주의를 기울이는 개별⋅순차적 전략이 가장 많이 나타났다. 복수의 물체에 동시에 주의를 기울이는 전체⋅동시적 전략을 사용하는 참여자의 비율은 공간 관계 과제에서 더 높았다. 결론 이러한 결과는 성인이 물체 특성 정보를 기억할 때보다 공간 관계 정보를 기억할 때 물체 사이의 중앙 지점을 물체의 상대적 위치 추출을 위한 참조점으로 활용하여 중심 영역에 시선을 고정할 가능성이 상대적으로 높다는 것을 보여준다. 또한, 공간 관계 기억을 위한 시각 주의 전략에 개인차가 존재함이 드러나, 공간 능력 함양을 위한 교육적 개입을 위한 기초적 정보를 제공한다. Objectives This study investigated the differences in adults’ visual attention to memorize object identities and spatial relations and analyzed the individual differences in visual attention during the same type of memory task. Methods We collected eye-tracking data from 32 college students during two different tasks: a task to memorize the colors of four objects and one to memorize the spatial relations among four objects. Participants were also interviewed about the strategies they had used for the tasks. The fixation metrics, saccadic metrics, and the self-report strategies were analyzed to detect the differences among individuals, as well as the differences between the two tasks. Results The eye-tracking data revealed that the proportionate fixation numbers and duration in object areas were greater during the object identity task than during the spatial relation task, with the average amplitude of saccades being larger during the object identity task. The differences could be understood through the heat map of spatial relation task, where the fixations were focused on the center area of the screen in addition to the object areas. The most common strategy in the both tasks was an individual-sequential strategy, which was allocating attention on a single object at once. The proportion of participants who reported a holistic-simultaneous strategy, which was allocating attention on multiple objects at once, was higher for the spatial relation task. Conclusions The results suggest that adults are more likely to fixate their eyes on the center area among the objects, when they memorize spatial relations than when they memorize object identities, utilizing the center point as a reference point to extract the relational position of the objects. Furthermore, there are individual differences in visual attentional strategies for the spatial relational memory. This study offers basic information for the design of an educational intervention to enhance spatial abilities.
