  • In many cases, the result of a road traffic accident can be described with more than one response variables. Nonetheless, most of the existing road accident data analysis deal with only one response variable and try to explain why it occurs. In this paper, we train association rules for a set of more than two response variables conditional on personal, environmental and vehicular/behavioral aspects of accident. Association rules are derived at 8% support and 70% confidence from the 1996 data of three police stations in Korea. We expect that these rules can contribute to effective safety practice in Korea.

  • 지리 정보에 대한 관심이 증가되면서 이러한 연구와 활용 분야도 다양해지고 있다. OGC(Open GIS Consortium)에서는 XML(Extensible Markup Language)을 GIS 분야에 도입한 GML(Geography Markup Language)을 개발하였으며 여러 활용 분야에서 GML을 사용하고 계속적으로 연구되고 있다. 본 논문에서는 기존의 XML 문서를 기반으로 연구되었던 데이터 마이닝 방법 중 하나인 연관규칙 기법(Apriori)을 GML 문서들에 사용하여 의미 있는 규칙을 찾아내려 한다. 규칙을 찾는 방법에는 2가지가 있을 수 있다. 하나는 GML 문서에서 내용만을 뽑아내어 그에 따른 규칙을 찾아내는 방법이고, 다른 하나는 GML 문서에서 사용된 태그와 속성을 기반으로 규칙을 찾아내는 방법이다. 본 논문에서는 2가지 방법을 통해 규칙을 찾는 것에 대하여 기술하고 2가지 방법을 적용한 시스템을 보일 것이다.

  • International commercial arbitration has established itself as the primary dispute resolution mechanism for international business transactions. Certainly, there are commonly-accepted standards that have evolved to reflect an internationally-harmonized approach to issues relating to the taking of evidence. This is reflected in International Bar Association("IBA") Rules for Taking of Evidence in International Evidence("IBA Rules"). This IBA Rules were revised in 2010. Designed to assist parties in determining what procedures to use in their particular case, IBA Rules present some of the methods for conducting international arbitration proceedings. Parties and arbitral tribunals may adopt IBA Rules in whole or in part - at the time of drafting the arbitration clause in a contract or once an arbitration commences - or they may use them as guidelines. They supplement applicable national laws and institutional or ad hoc rules. The IBA Rules were an ambitious undertaking, designed to overcome fundamental cultural differences relating to the taking of evidence under different national court systems. While it is difficult to assess how frequently the IBA Rules are actually adopted by parties, it is fair to say that they have had a considerable influence on the practice of taking evidence in international arbitration. This article mainly describes the essential provisions of IBA Rules, as revised in 2010, including but not limited to production of document, witnesses of fact, party-appointed experts, and tribunal-appointed experts. It also provides a comparison of relevant procedural rules of civil law and common law systems to each of the above mentioned provisions. It is important for arbitration practitioners to understand the differences in the taking of evidence under civil law and common law systems, respectively. This article will be helpful for practitioners and academics not only to understand the revised IBA Rules themselves but also to prepare for, and adequately deal with, the frictions that may arise as a result of the differences in approach for taking evidences. Indeed, so prepared, the arbitration practitioner will be able to anticipate the expectations, perceptions and the conduct of the parties, their counsel and the tribunal members.

  • 비 트랜잭션 데이터를 대상으로 연관 규칙을 도출하기 위해서, 데이터의 속성들을 구간화하는 기법들이 활발하게 연구되었다. 이러한 기존의 연구들은 구간화 단계에서 구간 범위의 변화에 따른 연관 규칙의 신뢰도 변화를 반영하지 않고, 구간화 단계와 연관 규칙을 도출하는 단계들을 독립적으로 수행하였다. 이로 인해 속성들의 구간이 부적절하게 설정되고, 이 결과 높은 신뢰도를 갖는 연관 규칙들이 최종 결과에서 누락된다. 따라서 본 논문에서는 속성들을 구간화하는 단계와 연관 규칙들을 도출하는 단계를 병합하여 동시에 수행함으로써, 가장 신뢰도가 높은 연관규칙들을 도출할 수 있는 구간을 설정하는 방안을 제안한다. 이를 위해서 연관 규칙의 우변의 속성들을 대상으로 계층적 클러스터링을 수행하고, 각 클러스터들에 대해서 특성 분석을 수행한다. 실험 결과, 제안하는 기법은 기존의 기법들에 비해서 높은 신뢰도를 갖는 연관 규칙들을 발견하는 것으로 나타났다.

  • This paper presents a hybrid data mining mechanism to extract expert knowledge from historical data and extend expert systems' reasoning capabilities by using fuzzy neural network (FNN)-based learning & rule extraction algorithm. Our hybrid data mining mechanism is based on association rule extraction mechanism, FNN learning and fuzzy rule extraction algorithm. Most of traditional data mining mechanisms are depended ()n association rule extraction algorithm. However, the basic association rule-based data mining systems has not the learning ability. Therefore, there is a problem to extend the knowledge base adaptively. In addition, sequential patterns of association rules can`t represent the complicate fuzzy logic in real-world. To resolve these problems, we suggest the hybrid data mining mechanism based on association rule-based data mining, FNN learning and fuzzy rule extraction algorithm. Our hybrid data mining mechanism is consisted of four phases. First, we use general association rule mining mechanism to develop an initial rule base. Then, in the second phase, we adopt the FNN learning algorithm to extract the hidden relationships or patterns embedded in the historical data. Third, after the learning of FNN, the fuzzy rule extraction algorithm will be used to extract the implicit knowledge from the FNN. Fourth, we will combine the association rules (initial rule base) and fuzzy rules. Implementation results show that the hybrid data mining mechanism can reflect both association rule-based knowledge extraction and FNN-based knowledge extension.

  • The purpose of this study was to investigate parental emotion regulation and children's understanding of emotional display rules. 31 boys and 29 girls of the first and fourth grades and their parents were selected for the subject. Sixty children were interviewed on eight interpersonal conflict situations and parent completed the PACES(Saarni, 1985) separately. The main results of this study were as follows. 1) Children's understanding of emotional display rules increased with age. 2) Children's primary justification for using emotional display rules was self-protective one. Girls used more often prosocial justification than boys. 3) Parental emotion regulation was significantly different between the two contexts: a child might cause another person substantial emotional distress and a child didn't cause another person substantial emotional distress. 4) Parental regulation was differed by children's age in the context that the child might cause another person substantial emotional distress. 5) Father's regulation was differed by children's sex in the context that the child might cause another person substantial emotional distress. 6) Maternal regulation was positively correlated to the level of emotional display rules in the context that the child might cause another person substantial emotional distress.

  • The purpose of this study was to investigate the effects of the family of origin variables on marital conflict. Seventy five married couples living together for less than 10 years were chosen from Seoul and Suwon cities. These subjects completed Korean Version of Family Adaptability and Cohesion Evaluation Scale Ⅱ, Individual Separation Scale, Family Rules Scale, Korea Certificated Egogram, and Marital Conflict Scale. The data were analyzed using descriptive statistics, paired-t test, and hierarchical regressions. The results were as follows: First, husbands and wives were different from each other in triangulation, family rules from family of origin and marital conflict. While husbands felt more strongly about their family rules than wives, wives perceived triangulation, and marital conflict higher than husbands. Second, husbands' controlling ego state, individuation, and family rules explained sixteen percents of husbands' marital conflict. Statistically speaking husbands' controlling ego state positively influenced on husbands' marital conflict. However, both of husbands' and wives' controlling ego states explained twelve percents of wives' marital conflict, and husbands' controlling ego state was statistically significant.

  • The purposes of this study were to investigate emotional display rules and intentions of preschool children, any gender differences and the emotional intentions according to levels of understanding of emotional display rules and positive vs. negative situations. The subjects were 58 six-year-old preschoolers who were individually interviewed using 7 hypothetical scenarios that assessed emotional display rules and intentions. The children showed more self-protective intention than other intentions, although there were no gender differences in using emotional display intentions. Children with high scores of emotional display rules frequently tended to use prosocial and self-protective intentions and also used different emotional intentions on positive vs. negative emotional situations.
