In this research, we propose a Unified Fuzzy rule-based knowledge Inference Systems UFIS) to help the expert in cosmetic brand detection. Users' preferred cosmetic product detection is very important in the level of CRM. To this Purpose, many corporations trying to develop an efficient data mining tool. In this study, we develop a prototype fuzzy rule detection and inference system. The framework used in this development is mainly based on two different mechanisms such as fuzzy rule extraction and RDB (Relational DB)-based fuzzy rule inference. First, fuzzy clustering and fuzzy rule extraction deal with the presence of the knowledge in data base and its value is presented with a value between $0\∼1$. Second, RDB and SQL(Structured Query Language)-based fuzzy rule inference mechanism provide more flexibility in knowledge management than conventional non-fuzzy value-based KMS(Knowledge Management Systems)

Certificate security oriented cyber certificate is important tool for the purpose of offering user-authentication service based on on-line system. In the paper, we analyzed management implement which could make the efficient use of certificate security oriented cyber terror response. This algorithm called SOL(Security Oriented Language) will make efficient use of the service about authentication consisting of the basis in the age of information through efficient management and partial use of each certificates. Especially, SOL could be used efficiently by grafting a small group of on-line system which is operated with particular purposes.

This paper investigates protocol architecture for a web-sensor gateway interconnecting internet and wireless sensor network, in which Zigbee sensors are connected over the IEEE802.15.4 communication protocol standard. The web-sensor gateway is to deliver data between TCP/IP and Zigbee/IEEE802.15.4 protocols, transparently. Since the gateway provides a means to remotely control and aggregate sensor data over the internet, it needs to be designed in the view point of users and in their convenience. In accordance, the common gateway interface technology satisfying users on the web browser to efficiently manage and query the sensors in the wireless sensor networks, ubiquitously, is also introduced. Finally, a simulation prototype for the web-sensor gateway is proposed and verified using OPNET simulation tool.

Computer-aided design (CAD)-based Monte Carlo radiation transport is of value to the nuclear engineering community for its ability to conduct transport on high-fidelity models of nuclear systems, but it is more computationally expensive than native geometry representations. This work describes the adaptation of a rendering data structure, the signed distance field, as a geometric query tool for accelerating CAD-based transport in the direct-accelerated geometry Monte Carlo toolkit. Demonstrations of its effectiveness are shown for several problems. The beginnings of a predictive model for the data structure's utilization based on various problem parameters is also introduced.

소프트웨어 산업의 발전에 따라 개발 수요의 충족 및 개발 효율성의 증대를 위해 다양한 개발 방법론과 개발 지원 도구들이 등장해 왔다. 그러나 데이터베이스 응용 소프트웨어(Database Application Software, DB-App)의 개발이 활발함에도 불구하고, 해당 분야 개발의 효율을 도모하는 방안에 관한 연구는 미비한 실정이다. DB-App의 소스 코드(Source code)에는 쿼리(Query)문이 빈번하게 사용되지만 작성 과정에서 오류가 발생하기가 쉽고 관리에 대한 어려움이 있다. 이는 개발 효율을 저하시켜 비용을 증가시키는 요인이 된다. 본 논문에서는 다양한 데이터베이스와 프로그래밍 언어로 개발되는 DB-App 개발을 지원하기 위한 방법을 기술하였으며, 사용자의 설정에 따라 쿼리문을 포함한 소스 코드를 생성하는 도구를 설계하였다.

BLAST, a basic bioinformatics tool for searching local sequence similarity, has been one of the most widely used bioinformatics programs since its introduction in 1990. Users generally use the web-based NCBI-BLAST program for BLAST analysis. However, users with large sequence data are often faced with a problem of upload size limitation while using the web-based BLAST program. This proves inconvenient as scientists often want to run BLAST on their own data, such as transcriptome or whole genome sequences. To overcome this issue, we developed NBLAST, a graphical user interface-based BLAST program that employs a two-way system, allowing the use of input sequences either as "query" or "target" in the BLAST analysis. NBLAST is also equipped with a dot plot viewer, thus allowing researchers to create custom database for BLAST and run a dot plot similarity analysis within a single program. It is available to access to the NBLAST with http://nbitglobal.com/nblast.

지금까지의 웹은 표현중심의 HTML에서 데이터의 구조적인 모습을 나타내는 XML로 그리고, 온톨로지 구축을 통해 의미 있는 데이터의 접근성에 초점을 둔 RDF, RDFS, OWL과 같은 형태로 변화하고 있다. 이러한 흐름을 통해 현재는 OWL을 이용하여 온톨로지 구축을 위한 연구가 진행 중이다. 이 논문에서는 구축된 온톨로지를 활용하기 위해 웹에 있는 OWL 파일을 http 프로토콜을 이용하여 접근을 하고 기존의 툴 종속적인 접근이 아닌 웹 표준 프로토콜과 OWL 파일 형식으로 접근하여 SPARQL 쿼리를 보낼 수 있는 웹 기반의 OWL 온톨로지 접근을 위한 SPARQL 쿼리 툴을 제안한다.

Re-engineering tools can substantially increase software maintenance productivity and the quality of maintenance work. Re-engineering usually involves changing the form(e.g.changining objects names and definitions, restructuring process logic) of a program. In this paper, we describe the design and implementation of InMaC＋＋ that is a software tool oriented towards maintenance of C＋＋ object oriented programs. With InMaC＋＋, programms can be displayed and edited in two forms : as the code and as the diagram InMaC＋＋ also contains transformations in both directions, i,e. from code to diagram and from diagram to skeletons of code. Hence, it is suitable for re-engineering and maintenance of existing code. Specially designed browsers implement the graphical interface. InMaC＋＋ contains a database that is based on a simple but effective data model of InMaC＋＋ programs. The model contains only four object classes and three relations, which makes the tool small, and easy to implement and use. A simple query language allows browsing through the database.

This paper suggests methods to chronicle and track the history of dialogues exchanged among characters to prevent logical errors of a story. As for stories that are long with many characters, especially in full-length novels and co-written stories, cognitive burden is imposed on a writer. If the writer has confused understanding of a character, then a logical error would enter the story. This would compromise completeness and integrity of writing. Against the backdrop, this paper shows how dialogues among characters are chronicled and tracked by using the aforementioned tracking methods through design of a writer support system that relieves a writer's cognitive burden while supporting the writing and through an analysis of existing novels. In addition, we showed the accuracy results of average 68.5% through the performance evaluation of the query used in the dialogue history tracking.
