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.

This study proposes a digital design method using a projective perspective, one of classical architectural principles, for architectural design profession. After observing fundamental principles of architectural design in projective geometry and its usage in design process, a digital method is proposed as an application to generate and develop architectural objects. The usage case of projective perspective method in two architects' design works was analyzed. As a bridge from the fundamental principles of architecture to contemporary practice, this study aims to relate the projective perspective to new generative approaches with the help of digital technology and make a contribution to design strategies of form-making in architecture. Previous research on projective perspective method with theory and practical issue was studied to find an adequate digital form-making process. Extensions of theory and design method related to projective geometry was sought to propose design possibilities utilizing digital technology. Also, method of using digital tool is presented in order to demonstrate the findings and issues to give directions in developing an expanded digital process.

The change in absorption and emission energy of several 7-amino substituted 4-methyl and trifluoromethylcoumarins in various polar, nonpolar, protic and aprotic organic solvents has been studied. The electronic transition energy including Stokes' shift are correlated with the orientation polarizability. Both the absorption and the emission transition energy decrease as the solvent polarity increases. The empirical solvent polarity parameters such as ET(30), π* are tested for their sensitivity and similar responses are observed.

〈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.

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.

Transglutaminase(TGase) catalyzes the Ca^2+ dependent acyl transfer reaction to from γ-glutamyl lysine cross-links between substrate proteins. we have examined the expression of TGase 1 and TGase 2 enzyme activity and protein expression in differentiation induced salivary gland cells(HSG), and human salivary adenocarcinoma cell lines(SGT)in reation to anchorage independent growth. The TGase1 and TGase 2 activity in SGT was higher than in HSG, and there is no significant difference between TGase 2 and TGase1 cells. HSG cells showed no increase in TGase 1 and TGase 2 upon reaching post confluence and in 1.8mM Ca^2+. Expression of the TGase 1 and TGase 2 was induced by high cell density or by high calcium in SGT. No induction of TGase 1 & 2 protein was observed in postconfiuent HSG cells, but there was notable increases in TGase 1 & 2 protein in post confiuent SGT cells. This pattern of TGase 1 & 2 protein expression correlates with the pattern of particulate activity. SGT cells showed more colony size and colony forming activity in soft agar rather than HSG cells. The ability of SGT cells, containing high levels of TGase 2 and TGase1,to form colonies in soft agar suggests a role for this enzyme in anchorage independence.
