  • In this study, the water content and the low calorific value of the dried sludge are analyzed by using a vertical cylinder type indirect heating type dryer for evaluatation of energy source value. The vertical cylindrical thin film dryer was an Okadora Pilot Plant, and the dryer was indirect heating vertical thin film type. The internal standard consisted of 500 mm in diameter and 700 mm in height. In the drying experiment, 10 kg of dehydrated sewage sludge was added to the dryer and the total amount of the sludge was adjusted to 27 times by variable of the time, the number of revolutions and the steam temperature. The results of analysis of the 27th experiment component of the dried product showed that the average low calorific value of about 11.2 MJ/kg and the water content of 6%. This is satisfy the fuel use standard of the thermal power plant of the sludge.

  • A study on the function of the Laurer's canal of Clonorchis sinensis was conducted with help of the light microscope, the transmission electron microscope, and the scanning elctron microscope. Some selected sexual organs concerning with the passages of the spermatozoa and the eggs were observed in detail. The conclusion of this study is that the Laurer's canal may be the copulatory organ of the female reproductive system as Miyazaki et al. suggested in case of lung flukes.

  • A 2-year-old, castrated male domestic short-haired cat was presented with dysuria. The physical and radiographic examinations were revealed the urethral stricture and rectourethral fistula after perineal urethrostomy (PU). A prepubic urethrostomy was performed to resolve these problems. After the treatment, the cat had normal urination and complete wound healing without any complications. This is the first case report on co-occurrence of the urethral stricture and rectourethral fistula after PU in the cat.

  • Purpose: Desmoplastic trichilemmoma is a rare variant of trichilemmoma. Histologically, it has a typical characteristic of trichilemmoma with epithelium of central portion and dense fibrous interstitium. There are only 4 reported cases of desmoplastic trichilemmoma arised in a nevus sebaceus, so we present a case of desmoplastic trichilemmoma arised in a nevus sebaceus with literature review.Methods: A 46-year-old female was clinically diagnosed as nevus sebaceous on left side of the forehead. Considering the facial contour, the mass was totally excised elliptically and direct closure was feasible with undermining subcutaneous layer.Results: Pathology report confirmed desmoplastic trichilemmoma developed from a nevus sebaceus and all tumor margins were negative. There were no evidences of tumor recurrence after surgical treatment.Conclusion: Desmoplastic trichilemmoma developed from a nevus sebaceus is a very rare tumor. Variant tumors can be developed from nevus sebaceus, so surgeon should be cautious in excising the mass totally and confirm the final pathology report.

  • This study represented experimental research on the flat-plate solar collector. The heat performances were measured the tube array surface temperature by thermal-couple. The solar collector($W{\times}H$) of $580{\times}1100$, various tilt angles of 30, 45, 60 degree and the internal tube number of 4, 6, 8, 10(ea) were utilized in the present investigation. It is found that the thermal concentration is higher as the tilt angle become larger and the solar tubes are more and more. In this stuby obtained results of following: The array of tubes in collector has the best nice in that the number of tube is eight and the tilt angle is 60 degree. The collect energy by each tube array shown high value by increase the number of tubes and tilt angles. In addition to, the collect energy depends on by the tilt angle than the number of tube.

  • We report an unrecorded taxon of genus Viola, V. grypoceras A. Gray var. pubescens Nakai, collected on Jeju Island, Korea. The distribution of this variety was restricted to the northern part of Japan, Hokkaido in particular. It is distinguished from V. grypoceras in that it is densely pilose except on its spur and lateral petals. We gave it the Korean name 'Tul-nak-si-je-bi-kkot' based on the morphological characters. In addition, some illustrations of this variety and a key to the V. grypoceras complex were provided.

  • An 8-month-old domestic shorthair cat presented with decreased activity and anorexia. Diagnostic imaging revealed cranial mediastinal mass and enlarged mesenteric lymph nodes. Fine needle aspirates showed a marked increase in malignant lymphocytes. Multicentric lymphoma (stage V-b) was diagnosed. The cat treated with COP protocol chemotherapy, and complete remission was induced. CNS relapse developed 314 days after the initiation of chemotherapy. Treatment with rescue protocol greatly reduced the clinical signs for a short period. The cat was in partial remission for 33 days and overall survival time was 383 days. Multicentric T-cell lymphoma with brain involvement was confirmed after necropsy by histopathology and immunohistochemistry.

  • 최근 딸기 생산이 확대 되면서, 고품질 다수확이 가능한 딸기 우량묘에 대한 수요가 빠르게 늘고 있으며, 딸기 육묘에 관한 관심이 더욱 늘고 있다. 그러나, 육묘시 작물에 따른 포트 혹은 트레이 선정에 대한 연구는 거의 이루어지지 않고 있다. 또한, 마이크로버블의 세정 능력은 이미 산업현장에서 널리 알려져 있으나 이를 이용한 시스템 개발은 농업분야에서는 미비한 실정이다. 따라서, 딸기 육묘에 적합한 마이크로버블 시스템을 설계하여 실증 개발함으로써 딸기 육묘 농가의 자립능력을 제고하고, 딸기 육묘 생산시스템의 확대 하여 농가소득 증대에 기여하고자 한다. 실험방법은 생육에 적합한 육묘용 트레이를 선정하고, 마이크로 버블 시스템을 적용한 육묘와 기존 방법에 의한 육묘의 비교 실험하였다. 포트의 용량에 따른 뿌린 근부의 성장변화를 관찰하고, SEM 촬영을 통하여 딸기 뿌리근부의 조직의 치밀성을 확인하였다. 기존 저면관수의 경우 딸기탄저병 확산을 억제하지만, 반입에 의한 감염주의 발병을 억제하는 것은 아니다. 따라서 포트 및 트레이를 청결하게 관리할 필요가 있으며 이를 해결하기 위해 미세기포(micro-bubble)를 사용한 클리닝이 상당한 효과가 있는 것으로 확인하였다. 또한 조직의 치밀도을 측정하기 위해 딸기 육묘 조직을 SEM 촬영하여 분석하였으며, 미세기포를 이용한 딸기 육묘 방법이 기존의 딸기 육묘 방법에 비하여 조직이 치밀한 것으로 확인 되었다. 또한 배지량 및 육묘 트레이가 딸기 육묘의 성장에 영향을 미치며 제1액아가 1개밖에 발생하지 않는 포기가 많아지고 '눈 없는 포기'의 발생 현상들이 발생하고 있어 적정 육묘 트레이의 선택 및 배지량 조절하는 비교 실험을 통하여 해결하였다. 본 연구의 결과 개선된 육묘트레이를 사용함으로써 제1액아의 형성이 촉진되어 정과방 후의 제1액과 방의 수확량이 증대한다는 것에 의해서 1월 혹은 2월부터의 수량이 증대되어 소득향상이 기대되며, 마이크로버블을 저면관수에 적용함으로써 트레이의 청결을 유지하여 병해를 예방하고 딸기모종의 조직을 치밀하게 함으로써 딸기의 우량육묘를 얻는데 기여 할 것으로 기대된다.
