The purpose of this paper is to show that when we consider the analytical ways of Dissimilation, it becomes clear that it is insufficient to deal with it in just linear and nonlinear ways. Thus within a new framework to be introduced in this paper, Harmonic Phonology, we will reanalyze the phenomenon. We will also consider how the Obligatory Contour Principle (hereinafter, OCP) is used as both rule trigger and rule blocker in rule application, and works as a universal constraint, that is, a filtering device of ill formed representation. As we also consider it under the new framework, we can show the application position and motivation of rules appropriately and represent the phenomenon synthetically. (Yosu National University)

기존의 혼합형 침입차단시스템은 네트워크 계층에서의 패킷 필터링 기능과 응용 계층에서의 응용게이트웨이 기능을 함께 수행하기 때문에, 모든 데이터가 응용 프로그램 계층에서 처리되는 게이트웨이 방식 침입차단시스템에 비해 성능이 뛰어나고 게이트웨이 방식 침입차단시스템처럼 다양한 접근제어가 가능하면서도 사용자에게 투명성을 제공할 수 있다. 하지만, 네트워크 계층과 응용 계층에 대응되는 보안정책을 각각 설정하여 접근을 제어하기 때문에 관리자의 침입차단시스템 관리를 용이하게 하기 위해서 일관성있는 사용자 인터페이스 개발이 요구된다. 본 논문에서는 혼합형 침입차단시스템을 위한 그래픽 사용자 인터페이스를 구현하여 접근제어 및 로그 분석, 실시간 네트워크 트래픽 감시, 날짜별 트래픽에 대한 통계처리와 같은 관리기능을 제공한다. 이 때, 접근제어를 위해서 새로운 규칙기술 언어를 함께 제안하고, 이를 이용하여 사용자가 요구하는 다양한 형식의 접근제어 규칙을 생성하도록 한다.

The linguistic characteristics of a sign language provide an important clue for an automatic construction of its expression from a given natural language sentence. For such characterization, we focus on the identification of elided constituents, the mapping of property-changing information into spatio-temporal dimension, and the need for rearranging the order of component information for enhanced quality of delivery. We use our characterization to implement a system that converts sentences in Korean into corresponding expressions in the Korean Sign Language.

With the growth of internet shopping malls, there is increasing interest in comparison shopping mall. However most comparison sites compare only book prices by collecting simple XML data and do not provide .the exact comparison Including precise shipping costs. Shipping costs vary depending on each customer's address, the delivery method, and the category of selected goods, so rule based system is required in order to calculate exact shipping costs. Therefore, we designed and implemented comparison shopping mall which compares not only book prices but also shipping costs using rule based inference. By adopting the extensible Rule Markup language (XRML) approach, we proposed the methodology of extracting delivery rules from Web pages of each shopping mall. The XRML approach can facilitate nearly automatic rule extraction from Web pages and consistency maintenance between Web pages and rule base. We developed a ConsiderD system which applies our rule acquisition methodology based on XRML. The objective of the ConsiderD system is to compare the exact total cost of books including the delivery cost over Amazon.com, BarnesandNoble.com, and Powells.com. With this prototype, we conducted an experiment to show the potential of automatic rule acquisition from Web pages and illustrate the effect of delivery cost.

트리 유형의 규칙들을 처리하는 기존의 규칙기반시스템은 실제의 규칙들을 절차형 프로그램으로 구성된 규칙 엔진에게 제공하여 결과값을 반환받는 형식으로 동작한다. 이와 같은 방식은 두 가지 단점이 있는데, 그 하나는 업무의 변경에 따라 규칙 엔진을 변경해야 한다는 점이고, 또 하나는 엄청나게 많은 규칙들을 가진 경우에는 규칙 엔진이 복잡해지고 규칙 엔진의 속도가 저하된다는 점이다. 본 연구에서는 ID 트리의 원리를 적용하여 규칙기반시스템에 사용되는 규칙들을 생성하는 규칙간소화 알고리듬을 제안한다. 제안하는 알고리듬은 규칙기반시스템에 필요한 최소의 규칙들을 생성할 수 있을 뿐 아니라 업무가 변경되는 경우 알고리듬의 수행으로 쉽게 규칙들을 생성할 수 있으므로 업무변화에 유연하다. 그리고 규칙 엔진이 필요하지 않아 수행속도의 향상과 경비 절감의 효과도 기대한다.

This paper introduces computerized version of Hangout(Korean Language) Standard Pronunciation Rule that can be used in Korean processing systems such as Korean voice synthesis system and Korean voice recognition system. For this purpose, we build Petri net models for each items of the Standard Pronunciation Rule, and then integrate them into the vocal sound conversion table. The reversion of Hangul Standard Pronunciation Rule regulates the way of matching vocal sounds into grammatically correct written characters. This paper presents not only the vocal sound conversion table but also character conversion table obtained by reversely converting the vocal sound conversion table. Making use of these tables, we have implemented a Hangeul character into a vocal sound system and a Korean vocal sound into character conversion system, and tested them with various data sets reflecting all the items of the Standard Pronunciation Rule to verify the soundness and completeness of our tables. The test results shows that the tables improves the process speed in addition to the soundness and completeness.

In this paper, a knowledge base editor is presented as a supporting environment for an expert system building tool, OPS5. The knowledge base editor is especially useful for the fast and easy development of a knowledge base when the OPS5 production language is used. This knowledge base editor has some special facilities such as syntax and type checking, rule browsing and automatic bokkeeping. The syntax and type checking provides the facilities to find syntax and type errors in an edited knowledge base, respectively. The rule browsing facility offers various pattern matching schemes to see the causes and effects of a concerned rule. Automatic bookkeeping keeps the updated date and user name of a rule for the later reference whenever a user adds or changes a rule.

Designing Trim die block is a complicated and time-consuming process heavily resting on the experience of the designer. To reduce design time and human errors, a knowledge base is used to automated the design process. In this paper, a framework of the Rule-based CAD System is presented for trim die block design consisting of a rule-base, design process control module and geometric modeler (CATIA). The rule-base includes design rules and know-how of design specialist. CATIA is used as the overall CAD environment and rule-base and design control modules are developed by C++ language with an interface to CATIA. Using the rule-base, the designer can explore alternating designs fast by changing design parameters and the part-list is automatically created which avoids miscommunication.

With the development of the Internet of Things technology, a system that ensures the self-adaptability of an environment that includes various IoT devices is attracting public attention. The rules for determining behavior rules in existing self-adaptation systems are based on the assumption of changes in system members and environment. However, in the IoT environment, flexibility is required to determine the behavior rules of various types of IoT devices that change in real time. In this paper, we propose a rule configuration in a self-adaptive system using SWRL based on OWL ontology. The self-adaptive system using the OWL - SWRL rule configuration has two advantages. The first is based on OWL ontology, so we can define the characteristics and behavior of various types of IoT devices as an integrated concept. The second is to define the concept of a rule as a specific language type, and to add, modify and delete a rule at any time as needed. Through the rule configuration in the adaptive system, we have shown that the rule defined in SWRL can provide flexibility and deeper concept expression function to adaptability to IoT environment.
