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.

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.

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.

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.

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.

최근 흡연을 시작한 젊은 성언에서 급성 호산구성 폐렴의 발생에 대한 증례가 보고되고 있다. 급성 호산구성 폐렴은 대개 발열을 동반하기 때문에 초기에는 감염성 폐렴으로 잘못 진단, 치료되는 경우가 많다. 아직 정확한 병태 생리 및 조직학적 소견은 밝혀져 있지 않지만 병력 청취 및 임상 양상, 방사선 소견의 관찰을 통해 급성 호산구성 폐렴을 의심하고, 진단을 위해 기관지 폐포 세척액 검사를 시행한다면 좀 더 쉽게 진단 내릴 수 있을 것이다. 본 저자들은 최근 처음 시작한 흡연에 의해 발생한 급성 호산구성 폐렴을 진단하고, 스테로이드를 투여하여 성공적으로 치료한 환자 2예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Acute eosinophilic pneumonia(AEP) is characterized by acute febrile respiratory illness associated with diffuse pulmonary infiltration and pulmonary eosinophilia. The specific etiology for acute eosinophilic pneumonia is elusive. By some investigators, cigarette smoking is suggested as a causative substance which can cause AEP. In recent, the authors experienced two cases of AEP following cigarette smoking. Both cases had characteristic features including age around 20 years, new onset smoking before occurance of AEP, diffuse infiltration on chest radiography, pulmonary eosinophilia based on bronchoalveolar lavage and acute improvement after steroid therapy. These clinical features are resemble with previous smoking induced AEP case reports. Base on these clinical features, cigarette smoking associated AEP could be diagnosed more easily.

In this study, the availability of pig slurry composting and biofiltration (PSCB) solution as an alternative for synthetic nutrient solution was determined by monitoring the growth and phytochemicals of lettuce (Lactuca sativa L. cv. ‘Salanova’). This study was conducted from 16 September 2011 to 31 October 2011. PSCB solution treatments were consisted of 1 time dilution (52N), 13 times dilution (4N), 26 times dilution (2N), and 52 times dilution (1N) which were based on the nitrogen concentration of a commercial liquid fertilizer for leafy vegetables (control). Subirrigation system was used to cultivate lettuce plants in pots containing commercial growing medium. As a result, all growth characteristics were the highest at control. Among PSCB treatments, PSCB 52N induced severe growth disorder at 28 days after transplanting (DAT) probably due to too high salinity. PSCB 1N also retarded the growth of ‘Salanova’ lettuce plants. This may be caused by high pH and/or imbalanced other mineral concentration except nitrogen of PSCB solution. In contrast, polyphenolic compounds with antioxidant properties were more abundant in lettuce with PSCB solution than control. However, further study is required to determine the certain factors of PSCB on the induction of phytochemical biosynthesis pathway. In conclusion, additional strategies should be developed to use PSCB solution as nutrient solution in greenhouses.

This study was performed to investigate the effect of surface design on bond strength of relining denture base resins to denture base acrylic resin. Heat curing resin(Lucitone 199, Dentsply U.S.A. and Vertex, Dentimex, Holland), self curing resin(Tokuso rebase, Tokuyama, Japan), and visible light curing resin(Triad, Dentsply, U.S.A.) were used in this study. The surface designs were classified as butt, bevel and rabbet joint and the bond strength was measured by Universial Testing Machine(Zwick Z020, Zwick Co., Germany). The obtained results from study were as follows; 1. The bond strength of Vertex resin was higher than those of Tokuso rebase and Triad. 2. The bond strength of rabbet and bevel joint was higher than that of butt joint. 3. The failure mode of Triad and Tokuso rebase was mainly adhesive, but cohesive failure was showed in Vertex mainly.
