A 2 months old female Korean domestic shorthair cat weighing 1.2 kg was come to hospital because of respiratory discomfort and lethargy. Heart sounds was more intense and clear on the right side than the left. On radiographic views, loss of the normal diaphragm line, undistinguishable shadow of heart, shadow of gas-containing intestines could be observed in thoracic cavity. Diaphragmatic herniorrhaphy was performed by using propofol 8 mg/kg IV and isoflurane without any complication. On 7th day after the operation, almost all the clinical signs and radiographs including diaphragmatic line, cardiac silhouette, liver and small intestines were turned to normal.

A sequestrated Mass of ectopic non functioning pulmonary Tissue artery is an uncommon but clinically recognizable Entity. Pulmonary sequestrated, in general usage, designates an intralobar process intralobar pulmonary sequestration is a rare congenital malformation characterized by a cystic portion of the lung that derive its arterial blood supply through aberrant vessel directly of systemic circulation. As aberrant systemic vessel supplying the lung was reported by Hurber in 1777. We experienced a case of Intralobar pulmonary sequestration Pre-Operatively, confirm by Aortogram. The operative finding show that large Abscess cavity measuring 7x8 Well circumscribed, child fist sized Mass, and 4cm-length aberrant vessel arising from Descending aorta Just above the Diaphragm. The Anomalous systemic artery was ligatures & resection, and associated with left lower lobectomy was done. Post-Operative course was uneventful, and 7 days later discharged.

Thoracic splenosis is a rare disease that develops as a result of autotransplantation of splenic tissue into the thoracic cavity following splenic and diaphragmatic injury. We report the case of a 53-year-old man with a chief complaint of heartburn and cough. He had a history of traumatic diaphragmatic rupture treated with surgical repair and splenectomy 15 years ago. Imaging studies revealed a paraesophageal mass, and surgical resection was performed considering the possibility of Castleman disease or an esophageal submucosal tumor. Pathologic results showed findings of normal splenic tissue. The patient was discharged on postoperative day 5 without any complications.

This case report describes the clinical presentation and successful surgical repair of a diaphragmatic hernia-related small intestinal strangulation in a neonatal foal. A nine-day-old foal presented with colic signs and respiratory distress. History taking showed that the dam of the foal experienced difficulty during delivery, and the owner assisted in delivery by pulling on the foal. Radiography and ultrasonography confirmed the diaphragmatic rent and the presence of a small intestine within the thoracic cavity. Surgical intervention was required to repair the diaphragmatic defect and address the intestinal strangulation. The diaphragm was reconstructed, and the nonviable incarcerated portion of the small intestine was resected and anastomosed using an end-to-end technique. This unusual case report provides insights into the surgical repair and outcomes of an acquired diaphragmatic hernia in a neonatal foal.

As a stator for steam turbine diaphragm, hollow-type nozzle stator to substitute for conventional solid one is introduced in this study. This hollowed stator can be separated into two parts such as upper and lower plates with large and curved surface area. This study focuses on thick plate forming process for the upper plate of the hollow-partitioned nozzle stator. First, to reduce forming defects such as under-cut and localized thinning of the deformed plate, and to avoid tool interruption between forming punch and lower die, tool design including the position determination of forming surfaces is performed. Uni-axial tensile tests are carried out using SUS409L steel plate with initial thickness of 5.00mm, and plastic strain ratio (r-value) is also obtained. Due to the asymmetric curved configuration of the upper plate, it is hard to adopt a series of blank holder or draw-bead, so the initial plate during this thick plate forming experiences unstable and non-uniform contact. To easy this forming difficulty and find suitable tool geometry without sliding behavior of the workpiece in the die cavity, two geometric parameters with respect to each shoulder angle of the lower die and the upper punch are adopted. FE models with consideration of 21 combinations for the geometric parameters are built-up, and numerical simulations are performed. From the simulated and predicted results, it is shown that the geometric parameter combinations with ($30^{\circ}$, $90^{\circ}$) and ($45^{\circ}$, $90^{\circ}$) for the shoulder angle of the lower die and the upper punch are suitably applied to this upper plate forming of the hollow-partitioned nozzle stator used for the turbine diaphragm.

선천성 횡격막 내장탈출은 드문 질환으로 산전 초음파로 횡격막 헤르니아와 감별하는 것은 쉽지 않다. 선천성 횡격막 내장탈출과 횡격막 헤르니아의 예후가 다르고 수술적 접근 방식이 다를 수 있어 정확한 감별 진단이 필요하다. 저자들은 산전 초음파 검사에서 선천성 횡격막 헤르니아로 진단되었으나 수술 시에 선천성 횡격막 내장탈출로 진단된 두 증례의 후향적 분석을 통하여 비록 출생 직후의 단순 흉부 사진으로는 두 질환의 감별 진단이 어려웠으나 연속적인 단순흉부사진에서 뚜렷하게 드러나는 병변 측 횡격막을 확인하는 경험을 하였다. 따라서 산전 초음파 검사에서 횡격막 헤르니아로 진단되었다 하더라도 출생 이후에 촬영한 연속적인 단순흉부사진의 주의 깊은 판독을 통한 재평가를 강조하고자 한다.

Five cases of traumatic diaphragmatic hernia were repaired in the Department of Thoracic Surgery, Seoul National University Hospital, during the period from 1967 to 1974. The first case, a 14-year aid girl, was diagnosed as diaphragmatic hernia during laparotomy because of jejunal perforation 3 days after traffic accident. Herniated stomach, transverse colon, spleen and left lobe of the liver were repositioned and the diaphragmatic rupture on left posterolateral portion was repaired with two layers of nonabsorbable sutures by transthoracic approach. The second case, a 26-year old man,was diagnosed immediately after traffic accident at a local clinic and transferred to this hospital 24 hours later. Herniated stomach, transverse colon and jejunum were repositioned amd diaphragmatic rupture,about 9 cm in length,from the posterolat.edge to the base of pericardium was sutured in two layers. The third case, a 26-year old man who had stab wound on the left lower lateral chest two years ago,was admitted with sudden abdominal pain and vomiting. Upper gastrointestinal series with barium meal revealed diaphragmatic hernia. The herniated stomach and transverse colon through the defect,about 3.5cm in diameter, at anterolateral portion on the left side,were repositioned and repaired with two layers of nonabsorbable sutures. The forth case, a 26-year old man, sustained blunt trauma to the chest by a roller and was transferred to the emergency room complaining of dyspnea 40 minutes after the accident. The diaphragmatic rupture extended from left midaxillary line to contralateral anterior axillary line,about 20cm long, at anterior portion of diaphragm, which was repaired with two layers, of nonabsorbable sutures. The fifth case, a 4-year old girl, had two separate diaphragmatic ruptures on both sides, which were caused by traffic accident. Immediate upper gastrointestinal series after injury showed herniated stomach, colon and spleen into left Chest cavity. Another small rupture with anterior edge of right lobe of the liver in chest cavity was noted. These were repaired with non-absorbable sutures via thoracotomy.

The frequency and distribution of lymphoma caused by bovine leukemia virus (BLV) infection in various organs were investigated. Lymphoma samples were obtained from slaughtered cattle or from cattle submitted to the National Veterinary Research and Quarantine Service, Korea. Thirty female Holstein-Friesian dairy cattle aged over three years with the BLV-associated lymphoma were studied. None of the Korean native cattle (Hanwoo) had lymphoma in this study however. Lymphoma tissues were gray to pink in color, soft in consistency, and bulged from the cut surface. In advanced lymphoma tissues, there was great variety in the appearance of involved structures due to hemorrhage, necrosis, and/or calcification. Neoplastic tissues were observed in lymph nodes in all lymphoma cases. Intestine (96.4%), heart (88.9%), stomach (73.1%), and diaphragm (62.5%) were frequently involved with lymphoma. However, there was no lymphoma detected in liver. Large neoplastic masses, sometimes reaching the size of over 20 cm, were found in the abdominal cavities. It is suggested that metastasis of lymphomas occurs mainly via lymph based on gross observations; neoplasia may have been initiated in the serosal surface of the lung, heart, peritoneum, and numerous hollow organs in the abdominal cavity. Also many organs in the abdominal and thoracic cavity were affected by neoplastic tissues simultaneously. Characteristics observed in this study could be used as criteria to differentiate BLV-associated lymphoma from other nodular lesions in the slaughterhouse and as fundamental data to make clear the mechanism of metastasis or pathogenesis of EBL.

A 23-month-old Holstein cattle showed excess salivation and reluctance of walking and suddenly died after forced sudden movements. Grossly, numerous fibrous adhesions were present within cranial abdominal cavity including the reticulum and diaphragm and thoracic cavity involving lungs, pericardial sac, and heart. A perforation made by a 10 cm-long sharp-ended wire was detected in the reticulum. Histopathologically, fibrous suppurative epicarditis and myocardial necrosis were observed. Fibrosis with neovascularization were found in lungs, spleen, and liver. And granulomatous reticulitis was observed. For differential diagnosis, no pathogenic bacteria were detected through microbiological tests and PCR results were also negative for bovine susceptible pathogenic antigens. Based on the gross and histopathological examination, we diagnosed this case as chronic traumatic pericarditis. Cattle are inquisitive and prone to swallow various kinds of metallic foreign bodies since they do not use their lips. Therefore, avoiding ingestion of metallic objects in animal feed and animal areas by careful environmental management of farms is required and farmers should give the adequate minerals and vitamins into the feeds not to lick or shallow foreign bodies in case of mineral deficiency. For veterinary practitioners, physical examination, blood tests, and diagnostic imaging (X-ray and Ultrasonography) are required for an exact diagnosis. Furthermore, placing the magnets in rumen would be effective for prophylactic administrations.

Thick plate forming is presented to manufacture a large and curved member of steam turbine diaphragm. Due to three-dimensional asymmetry of target geometry, it is hard to consistently keep the blank position in die cavity between forming punch and die. In order to relieve the position instability of the blank during the thick plate forming, a blank support structure is proposed to be composed of guide pins and linear bearing, and blank guide arm enlarged from both longitudinal ends of the thick blank. In this study, parametric investigations with regard to the geometric position and width of the blank guide arm are carried out. As main geometric parameters, 2 positions such as maximum curvature region and minimum one on a curved cross-section profile of the target shape are selected, and 14 widths of the blank guide arm are considered. Using 28 variable combinations, three-dimensional numerical simulations are performed to predict the appropriate range of the process parameters. The compatibility and validity of the blank support structure with the blank guide arm for the thick plate forming is verified through the thick plate forming experiments.
