<P>A 13-year-old female scimitar-horned oryx (<I>Oryx dammah</I>) died after progressive anorexia, weight loss, and depression. The necropsy showed that the retroperitoneum was compressed by a large white-to-tan uterine mass and on several sections of the mass, the uterine wall was markedly thickened because of ill-defined transmural tumor tissue. Metastatic nodules were detected in the omentum, mesentery, diaphragm, and lung. The genital tract and pulmonary and abdominal nodules exhibited highly pleomorphic sarcoma. The primary and metastatic neoplastic cells showed positive results for vimentin, desmin, and sarcomeric actin, and negative results for smooth muscle actin. Uterine metastatic rhabdomyosarcoma was diagnosed on the basis of the gross, histopathology and immunohistochemistry results.</P>

<P>A 3.9-year-old female African pygmy hedgehog (<I>Atelerix albiventris</I>) had a firm, tan-colored mass with an uneven surface arising from the mandibular salivary gland. A histopathologic examination revealed that the mass was composed of neoplastic proliferation of epithelial and spindle cells. The neoplastic spindle cells showed positive for vimentin, smooth muscle actin, calponin and cytokeratin 14 and, negative for cytokeratin 19, suggesting that spindle cells were derived from myoepithelial cells. Based on the histological findings and immunohistochemistry results, the mass was diagnosed as pleomorphic adenoma. Pleomorphic adenoma is the most common benign tumor found in human salivary glands, but it is rare in animals. To the best of our knowledge, this is the first report of pleomorphic adenoma in hedgehogs.</P>

Pulmonary fibrosis (PF) is defined as a gradual, interstitial fibrous disease of the lung parenchyma. PF causes collapse of the lung lobe, which can lead to lung lobe torsion of the other side. A 14-year-old male Pekinese dog was referred to the Veterinary Medical Center, Chungbuk National University. The chief complaint was acute dyspnea. The dog had a history of chronic cough, which lasted for 18 months, and the cough had recently deteriorated. Tachypnea was observed on physical examination. As a result of thoracic radiographs, ultrasonography, and computed tomography, lung lobe torsion and collapse were diagnosed. A postmortem examination revealed lung lobe torsion of the left cranial lobe and carnification of the right cranial lobe. Histologically, severe and diffuse interstitial fibrosis with distortion of alveolar architecture and severe congestion and/or hemorrhage were observed in the right cranial lobe and left cranial lobe, respectively. Although the cause of pulmonary fibrosis was undetermined, this case showed a typical lung lobe torsion caused by pulmonary fibrosis.

Canine heartworm disease is typically characterized by the presence of heartworms in the pulmonary artery and, to a lesser degree, the right ventricle. Systemic arterial dirofilariasis is an unusual manifestation of heartworm disease of dogs that results from aberrant migration of Dirofilaria immitis into the peripheral arterial circulation. A three-year-old Jindo dog was referred to the Veterinary Medical Center because of hindlimb lameness, paresthesia of hindlimbs, and interdigital ischemic necrosis. Angiography and ultrasonography were performed, resulting in diagnosis of heartworm infestation. In necropsy, entangled heartworms were present throughout the body, including lungs, kidney, small intestinal lumen, and arteries, in addition to the right ventricle and pulmonary artery. Histologically, lung showed adult heart worms in vessels, organized thrombotic vessels, and interstitial pneumonia featuring type II pneumocyte hyperplasia, thickened alveolar wall, and compressed alveolar spaces. Chronic parenchymal lesions, such as focal or diffuse necrosis, fibrosis, and dystrophic calcification were remarkable in liver and kidney. The current case showed a typical canine systemic heartworm disease caused by aberrant migration of Dirofilaria immitis.

The purpose of this study is to analyze the effect of Fisheries Resource Management by focusing on Fisheries management policy. The Fisheries management policy started from the late 1980`s, in Japan. The Japanese fisheries policy began in order to promote income equality among industries during the period of high economic growth. However, it shifted to fisheries resource management policy because fishing capitalization brought problems regarding the deplete of resource through excess fishing. This study provides a picture of the current situation in regards to the implement of this policy. First of all, fisheries management organization runs independently based on regional communities. Second, the activities of fisheries management organizations varies in terms of activities and organization implements on fisheries resource management policy. Third, management cost of resource management organization is increasing.
Drone for building fire suppression

introduction: Most of the developed cities are now highly populated with increased high-rise buildings. In general, high-rise structures are not preferred due to user perception of insecurity in case of fire and high cost of the building. Recently, there were fire accident occurred in an eight-story building that resulted in numerous causalities and property damage. Globally, there is a constant increase in fire accident in high-rise building. Based on the National Security Agency, the total number of fires in the apartment was 5,798. In that, the high-rise building fire accounted about 60.4% of all building fires. However, not much effort taken to reduce the rate of fire accidents especially in high-rise building. Purpose: The purpose of this study is to conduct a basic research on how to reduce a fire at an early stage by placing a fire extinguisher in the drones. It also aims at increasing the speed of fire fighters responses to reduce causalities and property damage. Method: First, this study adopted a method of launching a hand grenade type throwing fire extinguisher into a drone. We selected DJI Inspire 1 model with wide range of manoeuvrability, less affected by wind, and can withstand weight of the hand grenade type fire extinguisher (1.2 kg) also. In addition, we surveyed drone specialists and fire-fighters to determine the appropriate number of fire extinguishers and their location. Conclusion/Discussion: The survey concludes that a total of four hand grenade type throwing fire extinguisher could be installed in a drone and also the drone can throw the fire extinguisher at an angle of 100 degrees downward. However, the drones can fly about 15 minutes only. This survey also suggest that the fire drone would help to reduce fires in high-rise building and also it can reach fire sites six times faster than golden time. It is expected that about 2,000 ~ 3,000 drones to be placed in fire sites annually, particularly in high-rise building to reduce losses of both life and property

A 15-year-old castrated mixed breed dog presented due to a 5-month history of cough and difficulty in ambulation. Necropsy showed multiple periosteal and intramedullary infiltrative masses in the appendicular skeleton. In addition, single and multiple neoplastic nodules were observed in several organs, including the lungs, liver, kidney, and heart. Microscopically, several skeletal neoplastic masses and nodules in the parenchymal organs revealed similar changes. The neoplastic cells were spindle- to polygonal-shaped with prominent osteoid production and occasional cartilaginous and bone formation. Based on the gross findings and histopathology results, the case was diagnosed as multicentric osteosarcoma with systemic metastases.
