This paper is concerned with the program of the automatic mesh generation for 2-dimensional domain which contains the curved boundaries and holes. This program treats a new vertical - line drawing method. This method starts with 4-subdivisions of problem domain and the classification of the cross points of grid lines and boundaries. And the new node is generated by the vertical line to the line connecting the two intersections of a boundary and two grid lines in general. The boundaries are piecewise-curves composed of lines, circles, arcs, and free curves. The free curves are generated by B-Spline form. Although there were some bad elements for the complex boundary, it was possible to obtain the acceptable elements for the given boundaries. The results of automatic mesh generation can be verified directly by drawing on the computer monitor in executing the program. And it is possible to add the processes - that is, editing, hard copying, etc - using the script file in Auto-CAD.

Real-time RELP vocoder is implemented on the TMS320C25 DSP chip. The implemented system is IBM-PC add-on board and composed of analog in/out unit, DSP unit, memoy unit, IBM-PC interface unit and its supporting assembly software. Speech analyzer and synthesizer is implimented by DSP assembly software. Speech parameters such as LPC coefficients, base-band residuals, and signal gains is extracted by autocorrelation method and inverse filter and synthesized by spectral folding method and direct form synthesis filter in this board. And then, real-time RELP vocoder with 9.6Kbps is simulated by down-loading method in the DSP program RAM.

항공기 추진시스템에 있어 내구성과 신뢰성을 향상과 운용비용 절감을 위한 상태감시 및 진단 시스템의 개발 및 적용이 일반화되고 있다. 특히 40,000ft 이상의 고고도에서 장시간 운용되는 무인항공기를 신뢰성 있게 운용하기 위해서는 열악한 환경에서 작동되는 추진시스템의 손상이나 성능저하에 대한 사전 대처를 위한 상태감시 시스템이 필수적으로 요구된다. 이에 본 연구에서는 MATLAB/SIMULINK를 이용하여 온라인 상태감시 프로그램을 제안하였다. 입력 모듈에서 현 개발단계에서는 실제 엔진 계측신호가 유용하지 않아 이를 모사하였다. 제안된 온라인 상태감시 모니터링 프로그램은 적용 가능성을 확인하기 위해 실제 터보프롭 엔진에 적용하였다.

1990년대 3D CAD가 출현한 이후, 최근 BIM(Building Information Modeling)이 이슈화되고 있다. BIM이라 함은 건설 프로젝트 생애주기 전반에 걸쳐 생성되는 정보를 3D Model과 함께 관리하는 것으로, 건설 프로젝트 각 분야의 정보들을 3D 모델과 연동하는 프로세스를 가지고 있다. 이에 견적 분야에서도 3D 모델로부터 자재의 물량을 산출하는 연구들이 진행되어 오고 있으며, 국내l에서 상용화된 견적 프로그램을 국내 건설 프로젝트에 적용하려는 시도가 이루어지고 있다. 그러나 이는 2D 도면으로부터 물량을 산출하는 기존의 견적방식보다 작업시간 및 생산성 측면에서 효율성이 떨어질 뿐만 아니라, 국외 견적 업무는 국내 견적과 다른 방식으로 이루어지고 있기 때문에 국외 상용 프로그램을 국내 건설 프로젝트에 적용하는데 한계가 있다. 그러므로 국내 건설 프로젝트에서 3D 기반 견적 프로그램을 활용하지 못하고 있다. 본 연구에서는 국내 실정에 적합한 3D 기반 견적 프로그램 개발을 위해 우선적으로 고려되어야 할 3D CAD로부터 물량 정보를 견적 프로그램으로 전달하는 3D CAD와 물량산출 연동 프로그램을 제안하고자 한다.

The purpose of this work is to explain techniques achieved while developing a transient stability program which is suitable to Korean power system, and to add a module for contingency screening. It concentrates on the development of Contingency Screening Module. In this thesis, a fast contingency screening algorithm SIME(Single Machin Equivalent), which is one of the Hybrid methods for the transient stability assessment is used to develop the contingency screening module. The proposed module is applied to a KEPCO system, and simulation results obtained from the program are compared to those of commercial programs.

최근 인터넷 서비스 기술이 발달함에 따라 웹 서비스는 사용자의 컴퓨팅 환경에 많은 변화를 주었다. 시사, 경제, 게임/오락은 물론, 개인 금융까지도 웹 페이지를 통해 처리 된다. 이 때, 웹 페이지는 텍스트 형태의 코드를 전송받아 DOM 정보로 가공되어 웹 브라우저에 의해 사용자에게 보여 진다. 하지만, 이 정보들은 다양한 경로를 통해 접근이 가능하고 악의적인 목적으로 변조되어질 수 있다. 또한, 보안 매커니즘을 우회하여 사용자의 로그인 정보나 인증서를 획득할 수도 있다. 따라서, 본 논문에서는 이러한 웹페이지 변조 행위를 탐지하기 위해 웹 브라우저 중 대표적인 MicroSoft 사의 MS Internet Explorer의 Add-On 프로그램인 BHO를 이용하여 웹 컨텐츠에 대한 무결성을 검증하는 탐지 방법을 제안한다.

Evaluation in both an art and a science. The art of evaluation involves working with the management to agree upon purpose and users of results, creating design and gathering information that are appropriate for a specific situation and a particular policy making context. The value of evaluating extension p개grams has received a lot of attentions recently, and many extension educations see evaluation as an integral part of their work. The science of evaluation involves determining standards and developing indicatiors, selecting methods appropriate to gather information in a systematic way, analyzing information to assist in determining the value of the program in an objective manner. First, extension specialists have to consider relative merits about methods of gathering evaluation data. Selection of method should be influenced by the type of information desired, time availability, and cost of using the method. Second, good evaluations involve stakeholders at all stages including planning, implementation, and utilization of results. Third, far from being an "add-on ," evaluation begins with the initial planning of an educational program. Fourth, it is important for extension specialists that although evaluation is valuable and essential in any effective program, one of the biggest mistakes of extension program evaluators in to promise results that cannot possibly solve all the problems of project.

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

To help the blind to find the information easily on World Wide Web, this research has tried to develop the device which enables us to convert HTML for the general into HTML for the blind. This program consists of the items as follows: 1. Web Robot to gather the internet browser and the general HTML. 2. Restoring DB by Parsing process 3. Multimedia editor for the use of web DB to add the literal and acoustic description to the editing function. 4. Convertor which gathers the DB and then changes into HTML for the blind. This project is designed to make it easy for the manager to establish the web site for the blind. We expect that this program will basically help the blind to overcome the inequality in the common information.

The purpose of this paper was to develop manipulative materials to teach the angle concepts and construct a teaching-learning program by using that. Furthermore, this study analyzed how does the program affect students understanding of the angle concepts. To check the effects of learning activities with manipulative materials on the understanding of an angle concepts, applied observation during class and write a mathematics journal writing, a description of students impressions at the end of the class and analyzed before and after test paper. We find that students approached the subject more friendly and knew well about the mathematical concepts by using materials. Furthermore, this activity helped that way to solve add and subtract of the angle, estimate ability, round angle concept, positive response in mathematics learning.
