  • 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.

  • As the increasing interest about geographical information, such researches and applied fields become wide. OGC(Open GIS Consortium) developed GML(Geography Markup Language) which is adopted XML(extensible Markup Language) in GIS field. In various applied field, GML is used and studied continuously. This paper try to find out the meaningful rules using Apriori algorithm from GML documents, one of the data mining techniques which is studied based on existing XML documents There are two ways to find out the rules. One is the way that find out the related rules as extracting the content in GML documents, the other find out the related rules based on used tags and attributes. This paper describes searching the rules through two ways and shows the system adopted two ways.

  • 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.

  • To discover association rules from nontransactional data, there have been many studies on discretization of attribute values. These studies do not reflect the change of discovered rules' confidence according to the change of the ranges of the discretized attributes, and perform the discretization stage and the rule discovery stage independently. This causes the ranges of attributes not properly discretized, thereby making the rules having high confidence excluded in the result set. To solve this problem, we propose a novel method that performs the discretization and rule discovery stages simultaneously in order to discretize ranges of attributes in such a way that the rules having high confidence are discovered well. To the end, we perform hierarchical clustering on the attributes in the right hand side of rules, then do characterization on every cluster thus obtained. The experimental result demonstrates that our method discovers the rules having high confidence better than existing methods.

  • 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.
