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.

박은주 한국장애인고용촉진공단 고용개발원 2007 장애와 고용 Vol.17 No.1

직업재활의 과정과 취업은 정신장애인의 사회기술, 증상관리, 심리정서적 상태, 경제상황 등 다양한 요인들과 연결된다. 그리고 이러한 다양한 요인들을 충족시키고 직업재활의 성과를 높이기 위해서는 지역사회 내 사회복지 기관들 간의 네트워크를 구축하고 활성화시켜서 적합한 자원을 극대화시키고 서비스를 보다 효과적으로 제공할 수 있어야 한다. 이에 본 연구는 정신장애인들을 위한 지역사회 내 서비스네트워크에 영향을 미치는 요인들을 파악하여, 네트워크를 활성화시킬 방안을 논의하는데 목적을 두었다. 부산지역의 재활서비스기관들을 대상으로 실시한 설문조사에서 수집된 자료(n=70)와 각 기관이 네트워킹을 실시한 310개 기관과의 네트워킹을 통해 서비스네트워크의 특성과 네트워크에 영향을 미치는 요인들을 분석하였다. 그 결과, 네트워크의 구조에서, 전체적으로 네트워크밀도는 높은 편으로 나타났는데 네트워크 구성체계간 네트워킹 정도는 많았지만, 네트워킹 수준이나 내용은 정보제공이나 대상자 의뢰 및 전화접촉이나 대면접촉수준이었다. 둘째, 네트워킹의 정도에는 정신장애인에 대한 태도, 네트워킹의 경험, 친분정도, 자원중요도에 대한 생각, 기관의 서비스 수, 기관의 설립기간, 정신장애인을 위한 프로그램의 설치여부가 유의미한 영향을 미치는 요인으로는 나타났다. 또한, 네트워킹의 수준에 영향을 미치는 요인으로는 서비스 수, 정신장애인을 위한 프로그램의 설치여부, 서비스제공자의 근무기간으로 나타났다. The objective of this study was to explore factors affecting rehabilitation service network for employment of the mentally ill. Agencies engaged in rehabilitation for the mentally ill in Busan were surveyed about their network size, network contents, and natures. Data collected in the survey were analyzed with SPSS Win 12.0 and NetMiner 2.6 to explore the characters of service network for the mentally ill and the factors affecting network size and activation. The results of this study can be summarized as follow: First, the density of network was high(density=0.722). Second, most networkings were constructed by using 'phone-contact'. The contents of networking included 'exchanging informations' and 'committing clients'. Third, The degree of networking was affected by seven factors; attitude to the mentally ill, networking experience, degree of interpersonal intimacy in network, resource importance, the number of service served in agency, a period that each agency was founded and whether or not existing the programs for the mentally ill. The three factors had influence on the level of networking; work duration, whether or not existing the programs for the mentally ill, and the number of service served in agency. These study findings suggested that it should be focused on the staff education, developing instruments for networking, and a meeting for forming friendship, in order to facilitate the mentally ill's rehabilitation and strengthen the networking between the agencies.

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.

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.

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.
