Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

A 29 year old female patient came with grade NYHA Fc IV dyspnea of 1 month. No abnormality was heard during auscultation. Arterial blood gas analysis done due to shortness of breath showed a decreased PO_(2) of 64.6 mmHg. Computerized tomography(CT) was checked due to multiple nodules seen in both lower lung fields of the chest X-ray. CT revealed multiple pulmonary arteriovenous malformations in both the mid and lower lung fields. Dyspnea was uncorrected by the application of oxygen. Coil embolization showed improvement of PO2 and dyspnea. The CT follow up at 9 months after the procedure showed no progression of the arteriovenous malformation without any additional symptoms nor dyspnea.

김승혁,조길환 여수대학교 1997 論文集 Vol.11 No.2

The survey of traffic amount for the analysis of the traffic problems was done throughout Yosu's main principal streets and cross roads. Traffic amount was counted during peak time. The traffic amount was analyzed with HCM's service level analysis. The result tells that the traffics in Dongmoonro street, influx and efflux point of Hanjae Tunnel, and the street in front of Beach Hotel are very disorder. The traffics on Jungangro street, Mipyengro street, Kwangmuro street are quite delayed. As the result, most of street will be much confused unless there will be no construction of new road or improvement of traffic control applications. Also, the service level of the cross road is used by TRANSYT-7F model, so we analyzed the density of each cross road and a time lag by HCM method. I used these models to assume the maximum service of each crossing road.

지방중소도시 환경개선을 위한 Super Graphic에 관한 연구 : 아파트를 중심으로 Focus On Apartments

김기준,신승혁 경복대학 2001 京福論叢 Vol.5 No.-

도시공간에 있어 수퍼그래픽은 시민의 정서적 안정과 도시 미관을 개선한다는 입장에서 제작되기 시작했고 지금에 와서는 도시 환경디자인의 빼놓을 수 없는 분야가 되었다. 도시환경을 개선한다는 일차적 목적 이외에도 지역주민의 상징과 공동체 의식을 높여주고 때에 따라서는 랜드마크나 광고선전 매체로 활용되며 도시환경의 시각요소로서 수퍼그래픽은 도시민들에게 친근감있게 부합 할 수 있어야 하며 주거환경과 지역적 특성을 살려 대중적인 의미로 전달 활용되어야 한다. 그러므로 도시 아파트 수퍼그래픽을 체계적으로 연구 조사하여 현대 사회를 살아가는 인간의 생활환경에 맞게 개선할 수 있는 방안을 모색하고자 한다. 이에 지방중소도시 아파트의 수퍼그래픽을 중심으로 문제점을 제기하고 유형과 특성을 분석하여 특색있는 만드는데 도움이 되고자 한다. In urban spaces, Super Graphic has been produced focusing on improving civil emotional stability and urban beauty, and now is an indispensable field of urban environmental design. This has to improve not only urban environment but also regional resident symbol and community consciousness, be used for a landmark or advertising media on occasions, be familiar with urban citizens as a visual element of urban environment, and be used for a popular meaning considering residential environment and regional characteristics. Therefore this study focuses on systematically researching and investigating the Super Graphic that can harmonize with modem human living environment. And this is for the purpose of presenting a problems based on the Super Graphic of regional small and medium cities and analyzing their types and features to construct characteristic environment.

Patients die in the emergency department frequently ; however, there has been little about the incidence and cause of Emergency Department death in the emergency medicine literature. This study was conducted retrospectively to gain insight into the patients who die suddenly and unexpectedly in the Emergency Department(ED). A total of 360 patients were pronounced dead in the ED from 1991 through 1994 in Chung Ang Gil Hospital. Of the 360 patients, 309 (86%) were brought to the ED with cardiopulmonary resuscitation in progress or as do not resuscitation(DNR) patients, leaving 51(14%) patients who met the unexpected death criteria. Of the unexpected deaths, 32(62.7%) patients presented to the ED with either abnormal vital sign (24 of 32) or some alteration in consciousness (18 of 32), or both of them (10 of 56). Medical and surgical causes of death represented 47.1% (24 patients) and 15.6% (8 patients) of the unexpected deaths respectively. Trauma represented 19 (37.3%) of the unexpected deaths, with 14 of these being the result of motor vehicle collision. The yearly incidence of unexpected ED death is presented in numbers of deaths per 10,000 ED visits. In 1991, the incidence was 3.4, and in 1992, 1993 and 1994 those were 2.7, 2.2 and 2.1 respectively.

It has been documented that periodontopathic bacteria are also implicated in endodontic infections. 16S rDNA gene-directed PCR was to examine the prevalence of periodontopathic bacteria including Actinobacillus actinomycetemcomitans (Aa), Prevotella intermedia (Pi), Prevotella nigrescens (Pn), Porphyromonas gingivalis (Pg), Porphyromanas endodontalis (Pe), and Treponema denticola (Td) in the root canals of 36 endodontically infected teeth having apical lesions with or without clinical symptoms like pain, swelling, and fistula. 1. In 36 infected root canals, most frequently detected bacterial species was Pg (61.1%), followed by Td (52.8%) and Pe (38.9%). 2. Of 36 infected root canals, Aa was detected in 6 canals (16.7%) of the teeth, all of which showed clinical symptoms. 3. Of 36 infected root canals, Pi and Pn Were found in 4 (13.9%) and 5 (33.3%), respectively. Notably, prevalence of Pn in the symptomatic teeth was 50.0%. 4. One of black-pigmented anaerobic bacteria (BPB) including Pi, Pn, Pe, and Pg was detected in all of the teeth that showed pain or especially swelling but not fistula. It was, however, found that prevalence of BPB in the asymptomatic teeth or the teeth with fistula was only 40%. 5. Pe and Pg were detected in the teeth regradless of the presence or absence of symptoms. High prevalence of BPB in the symptomatic teeth but low in the asymptomatic teeth suggested that BPB may play an important role in the pathogenesis of periapical lesions.
