건설 생애 전 주기 중에서 기획단계의 지반 조사로 시작되는 흙막이 공법의 선정은 잘못 선정될 경우 해당 프로젝트의 공사비와 공기에 끼치는 영향이 매우 크다. 그렇기 때문에 공법 선정의 요인 및 프로세스에 관련된 연구가 많이 발표되었지만 일반인들의 활용이 어려워 실용화되지 못하고 있다. 본 연구에서는 본 연구의 선행연구에서 개발한 흙막이 공법 선정 프로세스에 기반하여 웹 기반 의사결정 지원시스템을 개발하였다. ASP.NET을 이용하여 사용자들의 접근성을 높이고 자료의 보완 및 수정이 용이한 웹 기반 시스템인 Dr. Underground로 발전시켰다. 이 의사결정 지원 시스템은 일반인들이 쉽게 접근하여 건축물 기본요구 사항과 대지 조건, 인접 대지 조건을 입력하면, 해당 프로젝트에 적절한 흙막이 공법을 선정해주고 그에 대한 상세 정보를 제공해준다.

Various protective equiptments are used for the power system control and protection. Numerous facilities are monitored at the same time in real time and introduction of optimization method and analysis of the method are required for generation control and facility management considering the demand fluctuations. However, the existing system analysis programs are difficult to link with the other sw and there are some problems with user convenience. To solve these problems the present conditions of the system are figured out in real time and the equipment insert method was estimated by optimization method, and the system that showed the system analysis program is developed. PSS/E has been used as system anlysis program for stabilizing system development which applied the optimization. method and Python language is applied in order to link the input and output values with the DB automatically. Lastly, DLL of matlab has been made included in C++ for solving the objective function using opmization method.By linking this to DB, power flow was calculated in PSS/E and the result was represented by Intouch screen.

본 논문은 1996년 W3C에서 웹문서의 표준으로 제안된 차세대 웹언어인 XML(extensible Markup Language)을 활용하여 고문헌의 원문을 디지털화하고 웹상에서 이용자들이 고문헌의 원문을 손쉽게 검색할 수 있도록 하기 위한 방안에 대해 연구한 것이다. 고문헌을 디지털화하기 위하여 일반고문헌을 위한 XML DTD(Document Type Definition)를 개발하고, 이 DTD를 토대로 실제로 XML 상에서 고문헌의 원문을 입력해 보고, 그 과정에서 발생하는 문제점과 기술적인 한계를 살펴보고, 향후 본 고문헌 XML파일의 국가적인 활용방안에 대한 시스템 모형을 구축하였다.

본 논문에서는 언어장애인용 문장발생장치의 통신율을 증진시키기 위한 처리방안으로 신경망을 이용하여 문장발생장치에 통사예측을 적용하는 방법을 제안하고 유용성을 확인하였다. 각 단어들은 구문론과 의미론에 따른 정보벡터로 표현되었으며 언어처리는 전통적으로 사전을 포함하는 방법과는 다르게 상태공간에서 다양한 영역으로 분류되어 개념적으로 유사한 단어는 상태공간에서의 위치를 통하여 알게 된다. 사용자가 의미심볼을 누르면 의미심볼에 해당하는 단어는 상태공간에서의 위치를 찾아가며 입력에 따른 동사예측의 중복성을 막기 위하여 신경망을 이용하여 클래스화한 후 동사를 예측하였고 그 결과 제한된 공간 내에서 약 $20\%$ 통신율 증진을 가져올 수 있었다.

The study was to find out the current situation of supply and demand of apparel CAD systems in Korea. Also it was hoped to gather any valuable information about the current usage of apparel CAD systems for the development of the enhanced apparel CAD system. Three interviews were carried out for the study. The first interview with the importing agents was to find out the apparel CAD system's supplying situation. The second interview with the users of apparel CAD system was about the usage of the systems and related informations. The last interview was about the pattern making facilities, which was pointed out by the users to be the most inconvenient part of apparel CAD systems. The results of the survey were: 1. The supply and demand of apparel CAD systems is increasing. 2. The education, training, maintenance of the system should be improved by the supplier. 3. Apparel CAD systems are used for various production systems in the apparel industry. 4. 100% of the systems are utilized for pattern input and 89% of the systems are utilized for marker making. Only 15% of the systems are utilized in pattern making process, which 80% of the users realize to be computerized. 5. The most serious barrier to the better usage of the system is the communication with the system in foreign language. This barrier could be lifted when Korean apparel CAD system is developed.

Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

The paper presets the improvements of MMI at the PROSET2000 correction program which is totally computerized system of the power system protection. The Base Form that is an open interface is developed to be able to compose the screen by reading the input screen from the database. It also is developed to be suitable for the environment of the Graphical User Interface instead of the DOS window when the users do the pannel settings. Program development in this paper is designed by Unified Modeling Language(UML) techniques.

This paper proposes a new method of vehicle brake lights detection and recognition using an R-filtering. Firstly, the proposed method processes the R-filtering with the first input image and then with the second one in order to detect brake lights. Secondly, the method counts the number of red pixels and computes the mean value in each R-filtered image. The difference rates between the numbers of the red pixels and between the mean values of two images are defined in this paper. Through the analysis of the difference rates, it can recognize whether brake lights are turned on or off, and whether the vehicle ahead is being approached or not. The proposed method is implemented using C language in an embedded Linux system for a high-speed real-time image processing. Experiment results show that the proposed algorithm is quite successful.

This paper proposes a new color segmentation method of vehicle license plates in the RGB color space. Firstly, the proposed method shifts the histogram of an input image rightwards and then stretches the image of the histogram slide. Secondly, the method separates each of the three RGB color components and performs the adaptive threshold processing with the three components, respectively. Finally, it combines the three components under the condition of making up a segment color and removes noises with the morphological processing. The proposed method is implemented using C language in an embedded Linux system for a high-speed real-time image processing. Experiments were conducted by using real vehicle images. The results show that the proposed algorithm is successful for most vehicle images. However, the method fails in some vehicles when the body and the license plate have the same color.

사람은 주로 언어를 통해 서로간의 의사를 표현한다. 하지만, 말을 할 수 없는 중증 장애인, 특히 전신마비 증세가 있는 중증 장애인의 경우에는 글을 쓰거나 몸짓을 통한 방법으로도 자신의 의사를 전달하지 못한다는 문제점이 있다. 따라서, 본 논문에서는 이러한 중증 장애인이 의사 소통을 할 수 있도록 안면근 신호를 이용한 의사 전달기를 구현하였다. 특히, 안면근 신호가 포함된 뇌파의 특징을 추출하여 이를 일반적인 제어 신호로써 변환한 다음, 이 제어 신호와 최소한의 자판을 연동시켜 문자를 선택하도록 함으로써, 중증 장애인이 효율적으로 의사를 전달할 수 있도록 하였다.
