Timely collaboration among businesses is required these days such as in B2B E-Commerce. That is, emergency requests or urgent information among businesses should be processed in an immediate mode. In this paper we investigate the semantics on timing constraints of timely collaboration among businesses in terms of event, data, and action and present ECA rule construction related to the timing constraints and its violation. The prototype is implemented using web-based active functionality component.

In the present study, by employing fragility analysis, the seismic vulnerability of a concrete girder bridge, one of the most common existing structural bridge systems, has been performed. To this end, drift demand model as a fundamental ingredient of any probabilistic decision-making analyses is initially developed in terms of the two most common intensity measures, i.e., PGA and Sa (T₁). Developing a probabilistic demand model requires a reliable database that is established in this paper by performing incremental dynamic analysis (IDA) under a set of 20 ground motion records. Next, by employing Bayesian statistical inference drift demand models are developed based on pre-collapse data obtained from IDA. Then, the accuracy and reasonability of the developed models are investigated by plotting diagnosis graphs. This graphical analysis demonstrates probabilistic demand model developed in terms of PGA is more reliable. Afterward, fragility curves according to PGA based-demand model are developed.

A number of medical schools in Korea have been using computer-based testing (CBT) for evaluating their students' scientific and/or clinical performance since the early 1990s. Introducing CBT to medical education would have several advantages: first, presenting figures and audio-video files of clinical content is simple with CBT, making it possible to evaluate medical students' competency with navigating more realistic clinical situations at minimum cost; second, CBT enables automatic item analysis and score reporting. To establish CBT, constructing an item bank with item parameters such as difficulty or discriminating parameters will be needed. To select more psychometrically sound items, analysis of the items according to item response theory is necessary. CBT has already been introduced in high stakes tests like the United States Medical Licensing Examination and the Medical Council of Canada Qualifying Examination. The National Health Personnel Examination Board in Korea is also planning to introduce a CBT-based version of the National Medical Examination soon. Thus all medical schools in Korea will need to introduce CBT and construct item banks to prepare their students for their licensing examinations and to measure the students' competency more accurately.

This thesis suggests fixed quantity model and detailed performance procedures of an information system audit. In addition, an identification of the check-items with high operating risk and factors that might lead to serious effects on the business are made. Then, this thesis proposes the information system audit model that can grant priorities. By using this model, the orderer can evaluate objectively with digitized mark. The model can improve the effectiveness, reliability, and objectivity of the audit by minimizing the discrepancies of different opinions about audit evaluation results between auditee and the orderer. The proposed model is adapted to an application system and audit projects of the database construction. As a result, the model has received an equal mark from the result of the general reviews, thus the propriety of the proposed model was verified.

In this paper, we designed data transformation interface for the automation of PCB product. The data designed to CAD does not exchange itself for the assembly line, so we analyzed the information of PCB components designed to CAD and developed human error detect algorithm. We also constructed database for the information of IC components. Developed the algorithm can change to the data suitable for the assembly line of PCB and this system was designed to do addition and revision of the components through the user interface. By automating existing manual processing, we were able to shorten the time of 1-2 days to several minutes and enhance reliability of the data and the efficient assembly line of PCB.

Molec-ular analysis was performed on the microflora found In the necrotic pulpal tissue collected from 5 infected root canals that were diagnosed as a periapical abscess. 16S rRNA coding gene (rDNA) library construction and sequencing were performed in order to identify the microflora, The 16S rDNA sequences from 278 clones were identified by a comparison with the database sequence in GenBank. Three phylum and 31 species, which were related to the oral microflora, were identified from the 3 samples (No. 87, 105, and 115). Dialister invisus (5.6％), Peptostreptococcus micron (18.3％), and Veillonella sp. (3.3％) were the organism present in all tee samples. Lac-tobacillusfementum (2.8％),Eubacterumsp./E. infirmum (6.7％), Shuttleworthiasatelles (3.9％), Psudorarnihacfer alactoiyticus (13.3％), Bulleidia moorei (2.8％), and Prevotella denticola (1.1％) were found in two samples. Two phylum and low species of environmental microflora were identified from 2 samples (No.95 and 101). The reason for this might be contamination of the samples with dental water. These results showed that molecular analysis could reveal more diverse microflora that are associated with endodontic infections than that revealed by conventional cultural methods. In addition, these results may of for the basic data to epidemiological studies related with endodontic infection.

This paper deals with the network interface of research and observation instruments in the oceanographic research vessel with an establishment of related database for measured information. The system is implemented to integrated communication network system which allows to effective survey by using real time observation and GUI(Graphic User Interface). The system also consists of the LAN systems and serial interface to link chemical, physical, biological and environmental relations. And, other network service and vessel data service for data communication between vessel and earth station such as INMARSAT-B, WWW service, BBS, E-Mail etc. are needed for integrated communication network system.

우리나라의 물관련 정보는 국토해양부 및 관련 기관에서 구축 및 운영, 개발 중에 있다. 이러한 시스템들은 치수, 이수, 환경 및 생태분야에 다양한 정보를 제공하고 있으나 제방에 관련된 다양하고 구체적인 정보를 획득하지 못하며, 시스템 DB간의 상호 연계가 어려운 실정이다. 따라서 제방에 대한 DB관리 및 향후 제방의 안전모니터링을 위해 정확하고 다양한 제방관련 DB구축이 요구된다. 이러한 제방관련 DB구축을 위한 과정은 다음과 같다. 제방제원 및 관리정보의 DB구축을 위하여 국내에서 수행하고 있는 사업인 하천일람의 "하천이력관리체계", 유역조사사업의 "WAMIS", 하천정보를 제공하고 있는 "RIMGIS"의 관련 자료를 분석한다. 기구축된 시스템과의 연계를 고려하여 물관리정보 표준과 RIMGIS 관련코드를 적용한 도형 및 속성 정보의 테이블 설계를 수행하며, 기구축된 시스템의 제방관련 수집자료 DB 및 관련 항목을 추가함으로써 제방제원 및 관리정보의 DB를 구축하도록 한다. 또한 향후 제방의 안전모니터링을 위한 관련항목을 포함하여 제방 유지 및 보수에 활용될 수 있도록 한다. 제방관련 DB구축은 치수시설물 안전모니터링의 기초를 마련하여 홍수방어 및 관리시스템 구축에 활용되어 인명 및 재산피해를 절감하고 기술수준을 향상시킴으로서 홍수 재해로부터 안전한 국토 건설 및 국민의 삶의 질을 향상시킬 것이다. 이러한 제방관련 DB구축은 기구축된 시스템과 연계하여 국가 홍수관리 시스템 구축, 치수능력증대, 장래유역단위 통합홍수방어 및 관리기술 개발에 기여할 것으로 판단된다.

The construction of a fingerprint database is important to evaluate the performance of an automatic fingerprint recognition system. Due to the cost of collecting fingerprints, there are only few benchmark databases available. Since it is hard to evaluate how robust the system is in various environments with the databases, this paper proposes a novel method that generates fingerprint images automatically from only a few training samples by using the genetic algorithm. Fingerprints generated by the proposed method include similar characteristics of those collected from the corresponding real environment. The proposed method has been verified by comparing with real fingerprint images, showing the usefulness of the method.

최근 노령화가 급속히 진행되면서 노화에 대한 연구가 활발히 진행되고 있다. 하지만 노화현상은 광범위한 표현형을 지니고 있는 생명현상으로 이에 대한 체계적인 연구를 지원하기 위한 웹포털 사이트가 필요한 실정이다. 특히 노화에 따른 질병과의 연관성 및 관련 유전자에 대한 정보를 수집하고 이를 체계적으로 분석할 수 있는 통합정보시스템은 향후 노화연구를 지원하기 위한 가장 핵심적인 요소라고 할 수 있다. 본 연구에서는 기존 노화와 관련된 461개의 유전자를 기반으로 관련된 질병과의 연관성을 OMIM 데이터베이스를 활용하여 분석하였다. 또한 관련 단백질의 기능을 GO데이터베이스 분석을 통해 유전자의 기능을 분석하였다. Pubmed에서 제공하는 노화관련 논문들의 MeSH 정보 분석을 통해서 노화와 관련된 용어를 분석하였다. 노화와 관련된 64개의 유전자를 키워드로 NCBI의 pubmed 데이터베이스로부터 관련논문을 다운로드 받아 생물학적 상호작용 정보를 추출했다. 생물학적 상호작용은 NCBI에서 제공하는 Metamap 데이터베이스를 기반으로 각각의 생물학적 용어를 정의했다. 현재 노화 유전자 64개에 대해 128,729개의 생물학적 상호작용 정보를 추출했고, 8대 노인성만성질환에 대해 301,176개의 생물학적 상호작용 정보를 추출하였다.
