본 논문은 인터넷상에서 사용이 가능하며 확장성이 뛰어나 XML(eXtensible Markup Language)을 다른 문서로 변환 및 브라우징(Browsing), 프리젠테이션(Presentation)이 가능한 표준 언어인 XSL(eXtensible Stylesheet Language)을 응용한 XSL 문서 편집 시스템의 설계 및 구현에 관한 것이다. 이를 위해 XSL문서의 기본 구조 단위를 패턴(Pattern)으로 구분하여 서식 집합(Template Rule)들을 사용자 서술 방식이 아닌 사용자의 선택 방식의 자동 생성으로 구성하도록 하였다. XSL 엘리먼트 (Element)의 선택방식은 구성되어진 XML문서를 읽어 들여 문서의 엘리먼트 정보를 확장할 수 있게 하였다. 또한 XML문서와 XSL문서의 HTML(HyperText Markup Language)로의 변환을 쉽게 확인할 수 있는 사용자 인터페이스(User Interface)를 구성하며 원활하게 문서를 교환 할 수 있도록 설계 구현 하였다.

Expert systems have a variety of potential applications in process control. The application domain ranges from the entire plant system to a single loop system. Both, off-line and real-time problems may be realized. In this paper, expert system is employed as a part of a single control loop of PID Controller with self-tuning. The goal of expert system in the present study is to build up the necessary process knowledge required for efficient control. In order to achieve this process, the development of an expert system and a prototype model is carried out. OPS5, a rule based production system, is utilized in experiment, and common LISP is used for man-machine interface.

BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In order to evaluate the performance of proposed BOM management system, which is very important to maintenance information system of urban transit. We develop component based BOM data and rule-set to design data structure that is mutually independent and integrated efficiently. It divides data whit management interface using component technology. The component based master BOM have advantage in database size and flexibility. Flexibility is measured as the number of updating records in accordance with added new product or engineering change. In database size, component based BOM is the best. we develop master BOM management system in web environment.

This paper describes the Weekly Load Forecasting Expert System(Named WLoFy) which was developed and implemented for Korea Electric Power Corporation(KEPCO). WLoFy was designed to provide user oriented features with a graphical user interface to improve the user interaction. The various forecasting models such as exponential smoothing, multiple regression, artificial nerual networks, rult-based model, and relative coefficient model also have been included in WLofy to increase the forecasting accuracy. The simulation based on historical data shows that the weekly forecasting results form WLoFy is an improvement when compared to the results from the conventional methods. Especially the forecasting accuracy on special days has been improved remakably.

A finite element model with the consideration of damage initiation and evolution has been developed for the analysis of the dynamic response of a composite sandwich panel subject to low velocity impact. Typical damage modes including fiber breakage, matrix crushing and cracking, delamination and core crushing are considered in this model. Strain-based Hashin failure criteria with stiffness degradation mechanism are used in predicting the initiation and evolution of intra-laminar damage modes by self-developed VUMAT subroutine. Zero-thickness cohesive elements are adopted along the interface regions between the facesheets and the foam core to simulate the initiation and propagation of delamination. A crushable foam core model with volumetric hardening rule is used to simulate the mechanical behavior of foam core material at the plastic state. The time history curves of contact force and the core collapse area are obtained. They all show a good correlation with the experimental data.

The main goal of e-learning systems is just-in-time knowledge acquisition. Rule-based e-learning systems, however, suffer from the mesa effect and the cold start problem, which both result in low user acceptance. E-learning systems suffer a further drawback in rendering the implementation of a natural interface in humanoids difficult. To address these concerns, even exceptional questions of the learner must be answerable. This paper aims to propose a method that can understand the learner's verbal cues and then intelligently explore additional domains of knowledge based on crowd data sources such as Wikipedia and social media, ultimately allowing for better answers in real-time. A prototype system was implemented using the NAO platform.

Full mold casting process is a new technique offering numerous advantages and promising possibilities. The present study is aimed to bring out the results of experiments carried out to study the effect of pattern coatings on the solidification of 99.5% pure aluminum plate-shaped castings in the various sand molds and the thermal behavior of the molds. The results of the investigation indicate that (i) with increase in pattern coating thickness, the relative chilling power decreases gradually for silica and increases for zircon coating, and (ii) the application of a pattern coating significantly reduces the maximum interface temperature by the mold which is more pronounced in the case of thinner mold wall. The investigation also indicates that Chvorinov's rule is not found to be valid for the casting in the full mold, with or without pattern coating. Therefore in full mold process, the pattern coating thickness will be a very important parameter in the study of thermal behavior.

In this study, a user-friendly expert system is developed for bright nickel plating processes which have a number of influence factors related to the plating quality. Because the mutual relations between these factors in the processes are not quantitatively identified, the expert system deals mainly with the troubleshooting process problems by using the production rule which is able to utilize effectively the qualitatives knowledge and the accumulated experience. Especially, to provide the system user with more timely and convenient informations about the cause of problem symptom and the corresponding countermeasure, it is introduced the interactive user interface using the Korean language. Also the knowledge base and inference engine of the expert system are completely separated, so that the substance of knowledge base can be easily updated and extended.
