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.

생태계 변화의 모니터링은 효율적 생태계 관리를 위한 기초 정보 수집을 위해 중요한 과정이다. 많은 생태 현상과 그 과정은 오랜 시간에 걸쳐 진행되므로 국립공원의 지속적인 보전 및 효율적 관리를 위해 생태계 모니터링은 장기적으로 이루어질 필요가 있다. 본 연구는 국내외 장기 모니터링 프로그램 사례 분석을 통해 성공적인 장기 모니터링을 위한 방법으로써, 최적화된 모니터링 설계, 표준화된 운용방안 마련, 인적 자원 및 DATA 관리 체계 수립, 안정적인 재정 마련 및 후속지원 등을 제시하였다. 이를 바탕으로, 현재 10년 넘게 수행되고 있는 ‘HS호 유류유출 사고 해역 장기 모니터링 프로그램’의 발전 방향으로 적응형 모니터링 방식이 적용된 표준화된 프로토콜의 정립, QA/QC와 지속적인 자료 관리, 조사 항목의 연계성 강화 등의 구체적 방안을 제안한다. 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.

In order to understand phytoplankton ecology in the Gulf of Yeong-il, climatic factors such as air-temperature, solar-radiation, evaporation, direction and strength of winds, and precipitation are studied from January 1982 to December 1985. Annual average of air-temperature during the four-years period is about 13.6C, ranging from 1.7C (January) to 26.5C (August). The maximum value of solarradiation is measured in spring (520MJm²in May), the minimun : in winter (62 MJm²in December, January or February), and the total annual value : about 4987MJm². Annual average of evaporation is about 1200mm (Maximum: 169 in May : Minimun: 56 in February), close to precipitation (about 1050mm). Annual average of strength of "North Winds" (350°-90°)is about 550m·sec for 156 frequences during 191 days, "West Winds" (170°-340°) : 511m·sec¹for 185 frequences during 148 days, and "South Winds" (100°-160°) about 61m·sec¹for frequences during 24 days. "N" winds is about 30% more violant than "W" winds, but both winds are influential in terms of water movements in the Gulf.

The distributed species and the kinds of viable microorganism in button or touch screen of machine was monitored according to coffee & soda machine and automated teller machine(ATM). Our purpose was to investigate the distribution of bacteria in button or touch screen of machine. Analysis of dispenser contamination was sampled from 8 location in Namseoul University for 3 months from September to November in 2011. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡsystems. The experiment on microorganism concentration of contact parts was carried out and the average of total microorganism was measured. The Coffee & soda machine and ATM was isolated and identified. The isolation rates of Gram positive cocci, Gram negative bacilli were 40.1%, 26.9% respectively. The frequently isolated bacteria were S. epidermidis, S. haemolyticus, S. warneri, Micrococus luteus/ lylae, Sphinogomonas paucimobilis . Further systematic studies are necessary with an emphasis on species identification Key Words : Microorganism, Coffee & soda machine, ATM

The present studies were undertaken to evaluate the effect of vitamin E, CCl_4 on the change of hepatic triglyceride, hepatic cholesterol, hepatic phospholipid in male rat. The result obtained from this study were summarised as follows: 1. Hepatic phospholipid of CCl_4 treated rat was increased in proportion to CCl_4 dosage but after concomitant injection(I.P) of vitamin E and CCl_4, hepatic phospholipid was significantly decreased in comparison to that of CCl_4 alone injection. 2. There was no effect on hepatic cholesterol concentration either CCl_4 alone injection(I.P) or concomitant injecton(I.P) of vitamin E and CCl_4. 3. Hepatic triglyceride of CCl_4-treated rat was significantly increased in comparison to that of normal rat but hepatic triglyceride of rat concomitant injection of vitamin E and CCl_4 was significantly decreased in comparison to that of CCl_4 alone injection.

The purposes of this study were to: (1) analyze students' educational needs and attitude concerning various areas in Home Economics as a college-level liberal education curriculum, (2) provide data concerning future curricula and efficient teaching method. Four areas of Home Economics were investigated: child and family, clothing and textiles, food and nutrition, and housing. The subjects of this study were 478 students of Chungbuk National University, divided by experiences in enrollment of Home Economics and teaching methods (managed by 1-2 teachers vs. team teaching by 4 teachers). The data were collected by questionnaires developed by the researchers and analyzed by frequencies, t-test and x²-test The major findings were as follows: 1) Child and family education, especially the subjects of child-rearing and parents education, was most needed area by students, and this area also got highest score in attitude. 2) In the field of clothing and textiles, the subject of impression management with clothing was needed the most, and the importance of clothing got the highest score in attitude. Also, the students enrolled Home Economics showed more educational needs and practical attitude. 3) In the field of food and nutrition, food safety and sanitation were the most needed subject and safety of foods making got the highest score in attitude. The students enrolled Home Economic showed more educational needs on the subjects of food safety and sanitation, human nutrition and health maintenance and the culture of food and nutrition. 4) Educational need of the students was the lowest in housing area, though the subjects of knowledge on the space planning such as interior design, use of living space, and indoor environments-heat, light and air got most attention. Educational needs and attitudes of the students were affected by student's sex, major (human vs. scientific), and age. 5) Educational needs and attitudes of the students were affected by sociodemographic variables, such as grade, sex, major (human vs. scientific), and age. And teaching method was also found to be an influential factor.
