악성코드에 대한 보다 바람직한 예방은 클라이언트측이 아닌 서버측에서 이루어지는 것이다. 본 논문에서는 새로운 개념 의 서버용 안티바이러스 엔진인 SAVE 1.0을 설계 구현하여 제시한다. SAVE는 기본적으로 1개의 AV모니터와 다수의 AV에이전트로 구성되어 있는데 다중 CPU를 장착한 병렬처리서버의 특징을 직접 활용하기 위하여 관리자가 다중쓰레드 기법을 직접 지정할 수 있도록 하고 있다 악성코드를 5가지 부류로 구분하여 바이러스 시그너쳐 DB를 구축 제공함으로써 부류별 진단을 지정할 수 있도록 하고 있으며 실시간 네트워크 패킷 검사를 통한 악성코드 유입 점검 기능도 제공한다. 웹 기반의 관리자 인터페이스는 뛰어난 사용자 편의성을 제공하고 있다. 성능실험결과 악성코드 검색율은 국내외 상용제품과 비교해서 매우 우수한 것으로 나타났으며 검색속도에 있어서도 서버의 CPU 수 증가에 거의 선형 비례하여 향상되는 특징을 보이고 있다. It is more desirable to prevent and detect the malicious codes in server system rather than in client PCs. In this paper, we suggest a new anti-virus engine, SAVE 1.0, which is executed on a parallel processing server. SAVE consists of 1 AV monitor and several AV agents. A system administrator can control the degree of multi-thread directly in order to enhance the utilization of parallel processing servers. Virus signature DBs in SAVE are classified into 5 categories, which support system administrator's options to use the classifier or not. By real-time checking of network packets, the influx of malicious codes can be prevented. Web-based GUI is one of the convenient functions provided in SAVE. In performance tests, we have confirmed that SAVE has higher virus detection ratio than any other AV engine, and SAVE has a desirable feature as an software of parallel processing servers since the performance of SAVE is improved almost linearly as the CPUs in a parallel processing server increases.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Monitoring ecosystem changes is an important process for collecting basic information for ecosystem management. Since many ecological phenomena and their processes take place over a long period of time, it is necessary to conduct long-term monitoring of ecosystems for the continuous conservation and efficient management of national parks. This study suggested an optimized monitoring design, standardized operation plan, human resource and data management system, stable financial preparation and follow-up support as methods for successful long-term monitoring through case analysis of domestic and foreign long-term monitoring programs. Based on this, it proposes specific measures such as establishing a standardized protocol with adaptive monitoring methods, continuous data management with QA/QC, and strengthening the linkage of investigation items in the development direction of the “HS oil spill accident long-term monitoring program” that has been conducted for more than a decade.

The incidence of tuberculous pleuritis is high in Korea where the disease is endemic. Diagnosis of tuberculous pleuritis is often problematic for its difficulty in detecting microorganism by stain or culture and sometimes it is not available and to obtain specimens from the pleura because highly invasive procedures are needed. Repeated pleural biopsy is almost always hard for patients. Recent studies on tuberculosis have interest on new methods for accurate and rapid diagnosis. Serologic assay is one of the new imerging diagnostic method for tuerculosis and extrapulmonary tuberculosis. Total 38 subjects admitted in the Department of Respiratory Division of Internal Medicine of Chung-Nam National University Hospital are involved in this study. Median age of patients with tuberculous pleuritis was 40 years old, ranging from 18 to 88 years. All patients were receving treatmented by combination anti-tuberculous therapy after the test. The cardboard folding device contained a nitrocellulose strip on which the 38-kDa antigen from M. tuberculosis has been applied. When a specimen (pleural effusion, serum) flows past the nitrocellulose strip, antibodies specific for the 38-kDa antigen bind to the antigen line. In a reverse flow, the bound antibodies are detected by a goat anti-human immunoglobulin G antibody conjugated to colloidal gold particles and show a pink to red positive line. The test is completed in a maximum of 15 minites. Two of the 38 subjects showed positivity. One case was from the pleura and the other from the serum. From the above data, we concluded that ICT Tuberculosis^( ) test is not effective in the diagnosis of tuberculous pleuritis.

〈Abstract〉 The purpose of this study was to examine the costume phenomenon of the New Generation by making researches their Fashion Style under the information age according to the development of Mass Media. The characteristic of Fashion Style of the New Generation in the modern Mass Media can be summarized as follows : 1. The Hip-Hap Style leads to the ordinariness of“Androgynous look”. The New Generation try to understand the taste of each other, the mind of each other, the social stratum of each other resulting from the vagueness of distinction of sex, and show the very open-hearted aspect. 2. The Reggae Style is introduced by the use of primitive and strong colors like the sun of Jamaica into a fashion. It is positively accepted by the New Generation who has indentified their Fashion Styles with those of pop-music star. 3. In the Cyber Style, metallic Cellophan textiles, Oil-skin textiles and Leather are used in the material, and from platinum to white, silver, gold, neon in the colors, This style is head for the future but it is also imitation. It means that pursuing not the real future but the sensibility of future.

This survey was carried out to investigate kinds and origins of flower languages of common flowering plants and standardize them. A flowering plant has about 5 kinds of flower languages. Differnt literatures have different flower languages for the same flowering plant. So differnt flower languages need to have standard flower languages. Flower languages originate from shape(8.0%) > color(7.5%) > characteristics(4.4%) > mythology and legend(4.9%) > scientific name(2.3%) > flowering time(1.8%) > perfume(0.9%) > and others(1.7%). The origin of 68.5% of flower languages was found to be obscure.
