Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

Background and Objectives: The colorectal cancer rates 4th in the total cancer prevalence in Korea. The clinical patient demographics were considered with the incidence rate of the colon and rectal cancer. The clinicopathological factors were analyzed for the 5 year survival rate. Materials Methods: Of the 282 patients who were operated from Jan. 1, 1992 to Dec. 31, 2001 and diagnosed by pathological biopsy as colo-rectal cancer, 234 patients were followed up. The age, sex, location of the cancer, TNM stage, operation method, histopathological classification, metastatic region, complications after operation and the survival rate were investigated. Results: Of the 234 patients, male and female consisted of 120 cases (51.3%) and 114 cases (46.7%), with an average age of 61.6 years. The average follow up period was 52.3 months and the peri operative mortality was 5.6%. The site of the cancer was most frequent at the rectum with 127 cases (54.3%). The patients were classified according to the TNM stages with 38 cases of stage 1 (16.2%), 98 cases of II (41.9%), 72 cases of III (30.8%) and 26 cases of IV (11.1%). The 5 year survival rate in the age group older than 50 was 63.3 % and 73.5% in the group younger than 50. In regard to the operation type, the 5 year survival rate was 65.4% for elective operation and 65.8% for emergency operation. The 5 year survival rate for well differentiated, moderately differentiated, poorly differentiated cancer, and mucinous adenocarcinoma was 73.7%, 60.2%, 58.3%, and 92.6%, respectively. The 5 year survival rate of each of the TNM stage is 81.1%, 74.8%, 57.0%, and 11.5% for Classes I, II, III, and IV, respectively. Conclusion: The clinical factors were analyzed for the 5 year survival rate with no statistical significance for the age, sex, and location of the cancer. The TNM stage and histopathological differentiation were statistically significant. The colon cancer showed better prognosis compared to the rectal cancer.

Cyclodextrin glycosyltransferase 생산균주를 토양으로부터 분리하여 형태학적, 생화학적 그리고 균주의 세포벽 지방산 조성분석에 의해 Bacillus brevis로 동정하였고, Bacillus brevis CD162로 명명하였다. 또한 배지조성에 따른 cyclodextrin glycosyltransferase의 최적생산조건을 검토한 결과, 2.0% soluble starch, 0.75% yeast extract, 0.5% bacto peptone, 0.2% KHPO₄, 0.05% MgSO₄·7H₂O, 1.5% Na₂CO₃ (pH 10.2)의 배지 조건에서 30℃에서 96시간 배양하였을 때 가장 높은 효소생산인 0.9 unit/ml을 얻을 수 있었다.(1997년 7월 10일 접수, 1997년 11월 21일 수리) A cyclodextrin glycosyltransferase-producing bacterium was newly isolated from soil using alkaline pH medium containg 1% Na₂CO₃, The isolated strain was identified as Bacillus brevis by morphological and biochemical characteristics, and designated Bacillus brevis CD162. The strain showed the best enzyme production of 0.9 unit/ml after 96 hrs of culture at 30℃ in a medium of 2.0% soluble starch, 0.75% yeast extract, 0.5% bacto peptone, 0.2% K₂HPO₄, 0.005% MgSO₄·7H₂O and 1.5% Na₂Co₃at initial pH 10.2

For the study on the changes of S-100 reactivity at the renal tubular epithelium of rats(SpragueDawley, b.w. 250± 20gm. male), the common bile duct ligation was performed under ether anesthesia. At 1st, 3rd, 5th and 7th day after operation, the S-100 immunoreactivity were compared with control rats. The results were as followings; 1. In the control rat, S-100 positive reactions were observed at the collectiong tubule, Henle's loop, distal tubule(partly) and renal papilla. 2. In common bile duct ligated rats, S-100 positive reactions were observed at the proximal convoluted tubule in the rats 1 day after operation, and at the collecting tubule and proximal convoluted tubule in the 3 days after operation.
직분식 디젤엔진용 연료분사계에 따른 분사특성과 엔진성능에 관한 연구

This study has focused on using fuel injections as variables for measuring performance and reducing exhaust gas in turbo-charger inter-cooler diesel engine. In experiments, we changed nozzle hole diameter, diameter of an injection pipe, and injection timing as variable. The results show that torque, fuel consumption and smoke are reduced as nozzle hole diameter decreases, while NOx increases. When the diameter of injector is reduced, torque, fuel consumption and smoke are deteriorated, but NOx is decreased. In addition, when the time for injection is advanced, torque, fuel consumption and smoke are improved, but the density of NOx is increased.

최근 들어 1km이상의 장대터널건설이 급증하는 추세이고 이로 인해 터널내 화재가 발생하면 터널내부는 외부와의 통로가 한정되고 고립된 공간특성으로 인해 화재로부터 발생되는 연기와 열로 대형인명사고가 발생 가능성이 높아지고 있다 그러므로 고속도로 터널의 경우, 터널화재에 대비한 기본적인 방재시스템을 구축하고 있지만 터널의 장대화, 화물운송차량의 대형화, 운반물류의 다양화에 따라 가연물의 규모, 터널내 기류등 다양화된 제반조건을 세부적으로 고려한 화염확산 형태 및 연기유동 메카니즘에 대한 연구가 필요하다. 따라서 본 연구에서는 고속도로 터널 실물화재실험을 수행하여 화재발생시 터널내부의 온도분포, 풍속, 연기거동 특성을 분석하였다. Recetly, the construction of tunnels longer than one kilometer has increased rapidly. Considering characteristic of limiting structure of longer tunnel, if fires inside tunnel broke out because of vehicles incidents, the catastrophic would have highly possibility to take place due to toxic smoke and heat of fires. In case of highway tunnel, safety facilities which can cope with tunnel fires are installed in the tunnel but according to rapid increase of heavy good traffic, dangerous goods and enlargement of tunnel magnitude, the research has to carry out about heat fluxes and smoke behaviour during tunnel fire. Therefore, through full-sized fire experiment the paper was analyzed that temperature distribution, wind velocity, smoke behaviour during tunnel fire.
