This study was directed at the design of a hybrid algorithm for competition relation extraction. Previous works on relation extraction have relied on various lexical and deep parsing indicators and mostly utilize only the machine learning method. We present a new algorithm integrating machine learning with various filtering methods. Some simple but useful features for competition relation extraction are also introduced, and an optimum feature set is proposed. The goal of this paper was to increase the precision of competition relation extraction by combining supervised learning with various filtering methods. Filtering methods were employed for classifying compete relation occurrence, using distance restriction for the filtering of feature pairs, and classifying whether or not the candidate entity pair is spam. For evaluation, a test set consisting of 2,565 sentences was examined. The proposed method was compared with the rule-based method and general relation extraction method. As a result, the rule-based method achieved positive precision of 0.812 and accuracy of 0.568, while the general relation extraction method achieved 0.612 and 0.563, respectively. The proposed system obtained positive precision of 0.922 and accuracy of 0.713. These results demonstrate that the developed method is effective for competition relation extraction.

Early conflict research in channel and organization area have focused on the definition of conflict construct, its cause, consequence and identified conflict resolution management. Recent studies about conflict, however, have explored new assumption of complexity, a multidimensional conflict construct, contextual conflict management strategies, positive and negative conflict/consequence, and the conflict resolution strategy. Although many literatures exists on channel conflict resolution, little research has been done about relationship learning and performance from conflict resolution perspective. This study explores how channel members can achieve a relationship learning, as a conflict resolution mechanism, which enhance co-created value in marketing channel relationship. Therefore we propose that conflict resolution strategies(collaborating behavior and avoiding behavior) influence channel performance(effectiveness and efficiency) through relationship learning processes(learning via information exchange, joint interpretation and coordination, relationship-specific knowledge memory), in view of buyer-seller relationship. The research model is shown at

This study is to understanding characteristics of Mathematical gifted children by comparing and analyzing of the learning strategies between gifted children and average students. The result of this study is as below. First, the mathematical gifted children's application ability on the cognitive meta-cognitive strategies and learning resources management strategies was higher than average students. Second, in case of learning resources management strategies between gender, male mathematical gifted students's t-test showed higher than female gifted students. Also, in case of average students, male student's t-test for the learning motive was higher than average female students. Third, mathematical gifted children are positive correlation among the learning motive, self-efficacy, cognitive meta-cognitive strategies, and learning resources management strategies. And in case of average student, it had a positive correlation among the learning motive, self-efficacy, and cognitive meta-cognitive strategies. But there is no correlation between learning strategies and cognitive meta-cognitive strategies.

The purpose of this study was to analyze the structural causal relationship between adult learners' participation in lifelong learning, education program satisfaction, and social capital. Also, the study reviews how education program satisfaction variables mediate the relationship between adult learners' participatory motivation and social capital. Subjects included 425 adult learners who participated in lifelong education, and the research hypothesis was verified through structure equation modeling analysis. Results are as follows: First, adult learners' participatory motivation had a positive (+) effect on social capital and education program satisfaction. Secondly, education program satisfaction had a positive (+) effect on social capital. Thirdly, education program satisfaction partially mediated the relationship between adult learners' participatory motivation and social capital and showed a significant indirect effect. This study suggests that it is necessary to develop various programs that can satisfy learners as well as improve social capital, participation motivation, and satisfaction of programs provided by lifelong educational institutions. Based on these results, this study suggests not only the role of lifelong education institutes, but also ways to improve social capital of adult learners within the lifelong education field.

The present study aims to investigate how Korean EFL learners' views of form-focused instruction, integrated and isolated FFI (form-focused instruction), are related to their beliefs about grammar and attention and how different these relationships are between high and low proficiency levels and between males and females in Korean college contexts. The findings indicated the participants' strong preference for integrated FFI, which was significantly correlated with two factors, attention in English class and English proficiency. On the other hand, the isolated FFI was strongly correlated with their beliefs about grammar learning, that is, independent learning of grammar and importance of learning grammar rules. In conclusion, the integrated FFI was associated with students' proficiency and attention, while the isolated FFI was related to their views of grammar learning. In conclusion, it is suggested that we need to use integrated FFI in Korean EFL contexts considering students' levels of proficiency and attention.

This is a literature review study on personality traits' role in language learning. Personality traits play an important role in language learning. In order to review research outcomes in recent studies, articles related to language learning and personality traits were collected through research databases such as ProQuest, Google Scholar, and EBSCO. Based on the analysis of collected literature, this study revealed that extraversion and openness to experience are the personality traits leading to the successful language learning. More specifically, extraversion was related to speaking skills while openness to experience was related to listening. It is also important to note which learning strategies are more likely to be utilized in second language learning and personality traits that are more likely to use them. These findings focus on writing skills, listening skills, and speaking skills. Further studies in the field are suggested.

The purpose of this study is to identify the relationship among the self-directed learning ability, academic self-efficacy and academic achievement of elementary school students. The subjects of this study were 197 sixth graders. The results of this study were as follows. First, the correlations among self-directed learning ability, academic self-efficacy and academic achievement were significant. Second, among the variables of self-directed learning ability and academic self-efficacy, self-confidence, preference for task difficulty, self-understanding of learner and independent mind of learning were positively related to academic achievement. These results imply the need for measures to increase these variables of academic efficacy and self-directed learning ability in the field of education in order to improve students' academic achievement.

In order to study the relation between self-directed learning readiness and mathematical inclination, we survey the adjusted SDLRS(self-directed learning readiness scale) of Guglielmino's model and the mathematical inclination, the recognition of mathematics for 2011 year engineering freshmen in D university. Research results are as follows: First of all, middle level engineering freshmen showed average level of self-directed learning readiness, and they had lower level of motivation, passion and time management skill. The relation of SDLR and the mathematical inclination was strong. Furthermore, SDLR and the recognition of mathematics in engineering freshmen was found to be the most closely related. Based on the results of the study, we suggest to study of strategies to elevate SDLR of engineering students and improve their achievement in college mathematics. Especially, we suggest that college mathematics for engineering freshmen must be focused on the improvement of SDLR.
