An eight-year-old, castrated male, a Schnauzer dog was presented with dysuria, hematuria and intermittent vomiting. Retrograde positive contrast urethrography was performed under fluoroscope. On the contrast examination, the leakage was observed in the prostatic urethra region and irregular filling defect was also shown from the prostatic urethra and the level of the trigon of the bladder. Surgical treatment was selected because of partial urethral obstruction and dysuria. The metastasis at the time of surgery was suspected, and the owner decided euthanasia. We detected lymph metastasis with immunohistochemical staining for pan-cytokeratins (CK) AE1/AE3, confirming their epithelial origin. This report described typical clinical findings, diagnostic imaging and histopathological examination of a prostatic adenocarcinoma.

Pneumoparotid is defined as the presence of air within the parotid gland or duct. Pneumoparotid is an extremely rare cause of parotid gland swelling. Pneumoparotid can be induced by air insufflation from oral cavity into the intraparotid salivary ducts, in condition like nose blowing, blowing up balloons, during extubation after general anesthesia while receiving positive pressure, rapid decompression while scuba diving, chronic attempts to suppress cough, and glassblowers. It can also be self-induced, and the literature contains an increasing number of reports involving pediatric and adolescent patients who induce parotid insufflation to avoid school or gain attention. Here, we report a case of pneumoparotid caused by habitual cheek inflating and improved with conservative treatment.

This study's aim was to confirm that pseudoneglect affects visual attention through car laterality, using a driving simulator with either bisection or quadrisection strategies being applied to road usage. On the pencil and paper tests, the left quadrisection and bisection marks deviated significantly to the left. While driving, the car was significantly lateralized to the right of the lane regardless of conditions. However, in terms of relative laterality, the biggest left laterality occurred on roads 1(bisection), while the smallest left laterality occurred on roads 2 (right quadrisection). Thus, the effect of pseudoneglect was demonstrated in both the pencil and paper tests and the driving simulation task. Also, roads 2 and 4, which were driven on the right side of the lane, showed a tendency for drivers to avoid the centerline, as this was the expected cause of right laterality. This study demonstrated that the pseudoneglect phenomenon can occur in a routine driving task.

In this study, we investigated the methods of computing deflection of the vertical and compared the results of deflections of the vertical computed from astronomical coordinates and GPS observations, and computed from PNU95, EGM96 geoid model. By comparing the results of the deflections of the vertical, we found out the followings; 1) The deflections of the vertical computed from astronomical coordinates and geoid models are similar to each other. 2) The difference between the deflections of the vertical computed from each geoid models was smaller than the difference of those computed from astronomic coordinates and geoid models. 3) The effects of distribution of the points on the results are less than those of the data used in the computation. If there exists reference data about the deflection of the vertical, it would be possible to evaluate the accuracy of the geoid model using this method.

우리는 보현산 1.8미터망원경에 장착된 고분산 에셸분광기 (BOES)를 사용하여 공생별V1016 Cyg의 스펙트럼을 얻었다. H alpha의 중심부가 포화될 정도의 장기 노출 관측 자료에서 H alpha의 날개 부분과 6545$\AA$ 근처의 He II 라만산란선, 4850$\AA$ 근처의 HeII 라만산란선을 확인하였다. 특히, 4850$\AA$ 근처의 라만산란선은 그 중심 위치가 원래 위치에서 0.8$\AA$ 가량 적색쪽으로 치우쳐 있으며, 우리는 이 현상이 라만산란단면적이 He II 972 방출선에 대하여 비대칭적이기 때문에 나타난다고 해석한다.

타액선을 구성하는 선세포의 종류는 달팽이의 종류에 따라 다양하게 나타났던 바, Walker(1970)는 병안목(Agriolimax reticiulatus)의 타액선을 광학현미경을 이용하여 2개의 성점액세포와 7개의 중성 및 장액성세포 그리고 1개의 순수한 장액세포 등 모두 10개의 세포를 관찰한 바 있고, Mclean(1970)은 Haliotis rufescens를 재료로 한 실험에서 타액선을 성하는 선세포는 오직 점액세포(mucous Cell) 한 종류뿐이 란 보고도 있었다. (중략)

일러스트레이션은 물체를 표현하는 최소한의 특징만을 가지고 사물을 표현하는 방법이다. 이를 자동화한 많은 연구들은 주로 많은 스트록을 이용하여 실제와 유사한 일러스트레이션 결과를 생성하고자 하였다. 본 연구는 물체의 특징만을 표현할 수 있는 적은 스트록을 이용하여 일러스트레이션을 생성하는데 목적을 둔다. 이를 위해 우리는 이전 연구[1]에서 간단히 추출된 경계선과 두 가지 스트록 모핑기법을 제시하였다. 본 논문에서는 물체의 특징을 표현하기 위해 유용한 경계선 추출 방법을 제시한다. 정확한 경계선의 추출은 스트록과 더불어 최종 일러스트레이션 결과에 많은 영향을 미친다. 경계선 추출 방법과 이전 논문의 스트록 모핑 방법을 이용한 일러스트레이션 결과는 본 논문의 실험결과로 주어졌다.

Recently, the city railway in the Seoul Metropolitan Area (SMA) has offered a low quality of service as a passage time, because it was operated slowly. So, the people who live in modern society are not satisfied about passage time, therefore, this study tried to make that the subway in the SMA becomes a more functional and effective wide-area-transportation-network through an express train introduction's method which examined cases from abroad and current system. and then presented how express train could be applied to current system. In a case study, We used the An-San Line and Su-In Line as a examples and developed a schedule which can minimize the delaying time of subway by using Branch & Bound Algorithm. The train operational plan was loaded to consider a railroad siding, Obtained site, and the dispatch interval(three to ten minutes) for the express and local lines and finally, We presented an alternative operational plan which made by those factors.
