  • This work presents a net-based structure to model approximate reasoning using fuzzy production rules, the Fuzzy Petri Net model. The Fuzzy Petri Net model is formally defined as a n-uple of elements. It allows for the representation of simple and complex forms of rules such as rules with conjunction in the antecedent and qualified rules. Parallel rules and conflicting rules can be modeled as well. We also developed an analysis method based on state equations and two fuzzy reasoning algorithms. Finally, the proposed method is applied to an example.

  • Signature-based intrusion systems use intrusion detection rules for detecting intrusion. However, writing intrusion detection rules is difficult and requires considerable knowledge of various fields. Attackers may modify previous attempts to escape intrusion detection rules. In this paper, we deal with the problem of detecting modified attacks based on previous intrusion detection rules. We show a simple method of reporting approximate occurrences of at least one of the network intrusion detection rules, based on q-grams and the longest increasing subsequences. Experimental results showed that our approach could detect modified attacks, modeled with edit operations.

  • The purpose of this study was to examine the awareness level of the prolonged sound rules in elementary school students. The participants in this study were 148 elementary school students in grades 1 through 6. Their awareness level of the prolonged sound rules was evaluated on reading tasks composed of 40 words and sentences. An one-way ANOVA followed by Scheffe hoc tests showed the showed the statistically significant difference between the groups for the awareness level of prolonged sound rules. The younger the children, the larger differences in the awareness of prolonged sound rules. The awareness might affect their cognitive development and a systematic instruction may be helpful especially in lower graders. In conclusion, the findings of this study showed significant differences in the awareness level of the prolonged sound rules at both words and sentences level. It was also found that as the age of children increases, the awareness level of the prolonged sound rules tends to increase which appeared to be completed by the 3rd grade.

  • If is interested and create rule between it in item that association rules buys, by negative association rules is interested to item that do not buy, it is attempt to do data Maining more effectively. It is difficult that existent methods to find negative association rules find one part of rule, or negative association rules because use more complicated algorithm than algorithm that find association rules. Therefore, this paper presents method to create negative association rules by simpler process using Boolean Analyzer that use dependency between items. And as Boolean Analyzer through an experiment, show that can find negative association rules and more various rule through comparison with other algorithm.

  • This paper presents techniques for discovering rules with elastic patterns. Elastic patterns are useful for discovering rules from data sequences with different sampling rates. For fast discovery of rules whose heads and bodies are elastic patterns, we construct a suffix tree from succinct forms of data sequences. The suffix tree is a compact representation of rules, and is also used as an index structure for finding rules matched to a target head sequence. When matched rules cannot be found, the concept of rule relaxation is introduced. Using a cluster hierarchy and a relaxation error, we find the least relaxed rules that provide the most specific information on a target head sequence. Performance evaluation through extensive experiments reseals the effectiveness of the proposed approach.

  • This study article is a study on the rules of origin review and rules of origin judgement. and The purpose of this article shall be studies to korea foreign law and Korea American FTA in origin country regulation. this article are two most important elements in determining market access in a FTA. that is the coverage of tariff elimination and rules of origin. The rule of origin in a FTA greatly influences the creation of economic profit and distribution. Therefor, The Result of the article is review to protection of domestic customers and domestic industries in rules of origin. This study contributes to a understanding of judgement of rules of origin and extend level of generalization of exchange law, WTO, FTA Regulations by review interaction relation.

  • In 1974 appeared the revision of Chapter 6 (which was then published as a sepprate monograph) of the Anglo-American Cataloging Rules (= AACR). The revision is the sum result of the incorporation of the many changes put forth in the International Standard Bibliographic Description for Monographic Publications (= ISBD (M)) including the prescribed punctuation and also the reorganization and and rearrangement, in much clearer and more accurate terms, of the previous 1967 AACR rules. The purpose of the present study is then to point out the major differences between the 1967 AACR rules and the revised 1974 AA CR rules (for Chapter 6) for the benefit of the cataloger in her actual task of descriptive cataloging. The article consists of three parts: (1) an examination of the Appendices, I, III, and V of the revised rules, which are necessary for understanding the revision of Chapter 6; (2) comparative analysis of the Seven Areas of the revised General rules commonly used in descritpive cataloging; and (3) comparative analysis of Special rules.

  • In this paper, the protective relay setting rules of Korean electric power system are studied by analysis of errors to be considered. An accurate operation of protective relays with accurate settings are important in power system reliability. The setting rules are used from the first establishment in 1982 and revision in 1990 Therefore, it needs revise and analysis of the setting rules because of environmental changes such as voltage raise or applied new technology of power system. Two major setting rules are studied. One is the rule for Zones of distance relay for transmission lines. The other is the one of differential current in a differential relay for power transformers. The range of errors in the setting rules accepted in the field experience is studied in simulation of case study. Also some guide lines for the range of errors in the setting rules are presented from the case study using Matlab simulation.

  • 사회복지기관에 근무하는 사회복지인력들의 행동은 기관의 공식적 지침들에 의해서 뿐만 아니라 공식적으로 명문화되어 있지 않은 숨은 규칙, 불문율, 또는 관행들에 의해서도 실질적으로 많은 영향을 받는다. 본 연구는 사회복지기관의 실제적인 운영에 영향을 미치는 복지기관 내 "숨은 규칙" 존재의 정도를 양적으로 측정해 보고, 그 규칙들이 기관에서 일하고 있는 사회복지 인력들의 기관헌신도, 만족도, 소진에 어떤 영향을 주는지를 탐색해 보았다. 또한, 복지 기관 종사자들이 기관에 존재하는 숨은 규칙들을 따르지 않았을 경우 받게 되는 개인적 피해, 숨은 규칙의 존재 정도에 따른 기관의 이익/피해 상황도 함께 살펴보았다. 연구 결과 우리 사회의 사회복지기관에는 숨은 규칙이 심각한 정도로 존재하지 않는 것으로 나타났다. 숨은 규칙의 미 준수로 인한 개인피해도 심각하지 않은 것으로 나타났다. 다만, 숨은 규칙이 많이 존재할수록 기관은 여러 가지 피해를 입을 수 있음이 밝혀졌다. 또한, 숨은 규칙이 많이 존재할수록 사회복지사들의 기관에 대한 헌신 및 만족도가 낮아지고, 소진의 수준은 높아지는 것으로 나타났다. 숨은 규칙들 영향력이 상대적으로 크게 나타난 내용은 사회복지사는 전문적 업무수행보다는 무슨 일이든 다하도록 요구받고 있다는 것과 근무시간 외 근무를 당연시하고 있다는 것이었다. 명시적 규칙이 있는 그대로 잘 지켜지고 있는 부분은 사회복지실천 윤리와 관련된 내용이었다. 영향력 있는 숨은 규칙들을 중심으로 사회복지실천 내실화 방안이 간략히 제시되었다.

  • 소프트웨어의 성공적인 개발을 위해서는 체계적이고 명확한 요구분석이 이루어져야 한다. UML에서는 유스케이스 모델링을 통해 사용자 또는 고객의 요구사항을 파악하고 업무 시스템의 범위를 결정하는 방법을 제공하고 있다. 본 논문에서는 효율적이며 정확한 유스케이스 모델링을 위한 연구의 일환으로, 요구사항 기술서로부터 정형화된 규칙을 적용해 가면서 단계적으로 유스케이스 다이어그램을 추출하는 기법을 제시하였다. 요구사항 기술서 관련규칙( $R_{A}$; Rules for Requirements Specification)을 적용하여 요구사항 기술서를 변경하고, 변경된 요구사항 기술서에 액터 추출 규칙( $R_{A}$ ; Rules for Actors), 유스케이스 추출 규칙( $R_{U}$ ; Rules for Use Cases), 관계 추출 규칙( $R_{R}$ ; Rules for Relationships)을 각각 적용하여 액터, 유스케이스, 관계를 추출하여 최종적으로 유스케이스 다이어그램(Use Case diagram)을 작성하게 된다. 본 논문에서 제시한 규칙을 인사관리 요구사항 기술서에 적용해 본 결과, 정형화된 규칙이 없이 서술적인 몇몇 조언을 바탕으로 유스케이스 다이어그램을 추출해야하는 기존의 어려움을 줄일 수 있는 효과를 확인하였다.확인하였다.
