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.

〈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 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.

Many changing mankind's thought and recognition have affected our history, it is same that dance has become a new concept-dance art under the concept that experiment of a new formality and change are creation. Dancer's feeling is exposed through dance is a phenomenon of carrier which independently embodies self. Dance is a harmony between time and space and a harmony made by rhythmic movement and dance composition. Dance is an art expressing feeling and some situations intentionally dr not by moving its body. The way of communication has been changed since the introduction of the New Dance. In traditional dance, there was no sharply defined boundary to divide spectators and performers, that is, the object and the subject of communication. With the New Dance, there established modern theatres, which separated performers from spectators. With the New Dance, the dance itself became interpretive activity. The New Dance remodelled the traditional dance and introduced some element of ethnic dance from other countries. For example, the costume became so diversified in the New Dance that the range of expression also became expanded greatly.

The present study was carried out to exanine the morphological changes and TRACP (Tartrate resistant acid phosphatase) activity in the resorption of mandibular bones of mouses resulted, established by low calcium diet. Mice were divided into two groups; one was the calcein group for fluorescent microscopy, the other was the non-calcein group for light and electron microscopy. After calcein injection, mice(ICR) were fed either a low calcium diet (0.01% Ca, 0.75% P) or control diet (0.1% Ca. 0.75% P). Non-calcein group were also fed a low calcium diet or control diet. Mice were sacrificed on 3, 7 and 14 days. For fluorescent microscopy study, fixed undecalcified alveolar bones were embedded in Epon 812, and ground sectioned to study the new bone formation after calcein injection. For the TRACP histochemical study, fixed decalcified alveolar bones were incubated in p-NPP (p-nitrophenyl phosphate) media. For the transmission electron microscopic study, incubated alveolar bone were post fixed in OsO_(4), embedded with Epon 812 for the study of TRACP localzation and activity. The observed results were as follows. 1. Low calcium diet induced bone resorption in buccal and lingual sides of alveolar bone, while the lingual side of alveolar bone was not resorbed in the control group. Bone resorption increased over the period of low calcium diet. 2. The alveolar bone proper of the lingual alveolar bone continued to deposit new bone of the periodontal side even after the low calcium diet. 3. After low calcium diet TRACP activity increased in the cytoplasm of osteoclast, extracellular ruffled border. TRACP activity was also found at the eroded bone matrix after bone resorption, and in the cytoplasm of detached osteoclast. In the immature osteoclast enzyme activity was confined in rER. No enzyme activity was found in the osteoblast.

The purpose of this study is to explore the aspect of change in literacy level of preschoolers through project ‘Hangeul’. While the project <Hangeul> was implemented from October 2019 to November 2020 with the research participants, a three-year-old girl and a five-year-old boy, the data were collected through participant observation, in-depth interviews, and other references during the course of the project, and was analyzed and interpreted through a qualitative method regarding the change in literacy level of the preschoolers. The result of this research proved that the learning activities of the project ‘Hangeul’ changed the reading literacy level of the preschoolers. The project ‘Hangeul’ changed the reading behaviour of the preschoolers. Their inner motivation to read was enhanced by experiencing diverse environmental print in their daily surroundings. Also, their ability to read increased from reading a variety of kinds of literature including encyclopedias, comic books, and dictionariy. In conclusion, a positive change in the literacy level, in other words, the reading behaviors of preschoolers could be found through the project ‘Hangeul’. 본 연구의 목적은 유아들의 일상과 놀이의 장면에서 ‘한글’을 주제로 함께 탐색하고 표상하 고 문제를 해결해가는 프로젝트 활동을 통하여 유아의 읽기 문식성 변화가 어떠한지 심층적으 로 알아보는 것이다. 본 연구는 2019년 10월부터 2020년 11월까지 연구자가 만 3세 여아와 만 5세 남아와 함께 '한글' 프로젝트 활동을 실행 및 전개하면서 Spradley의 12단계 참여관찰과 심층 면접을 통해 일상에서 이루어지는 유아들의 놀이와 상호작용을 깊이 있게 관찰 및 기록 함으로써 다양한 자료를 수집하여 유아의 읽기 문식성 변화를 중심으로 분석하고 해석하였다. 연구 결과, 유아들은 ‘한글’ 프로젝트를 통하여 일상의 주변 환경에서 다양한 환경 인쇄물을 경 험함으로써 읽기에 대한 내적 동기가 향상되었으며, 이러한 유아의 내적 동기를 따라 백과사 전, 만화책, 국어사전 등 다양한 종류와 장르의 책들을 찾아보며 함께 대화를 나누고, 책 읽기 에 대한 즐거운 경험을 통해 유아의 읽기 능력이 향상되었다.
