The purpose of this study was to investigate the role of phonology in lexical access of bilingual processing for Korean-English bilinguals. Four experiments have been conducted in order to adjudicate the nonselective lexical access hypothesis, which argues simultaneous phonological activation of two bilingual languages, and the selective lexical access hypothesis. which argues phonological activation of only one bilingual language. The results showed that the Korean target word processing was significantly affected by the phonological manipulation of the English target word(Exp. 2). Similarly, the English target word processing showed the tendencies that it is affected by the phonological manipulation of the Korean prime word(Exp. 2). This results indicates that the phonological information of another bilingual language is automatically activated when we process one of bilingual languages, and the process of English which is the second language for most Korean, is phonologically activated.

Fraction is one of the concepts which are difficult to elementary school students. So, many researches about fraction were performed in mathematics education research. In special, fraction has so many subordinative concepts-proper fraction, improper fraction, mixed number. We have to concentrate on the conceptual understanding in teaching of fraction. In this case, a mixed number and improper fraction are concepts which can convert respectively. And there are methods that a mixed number and improper fraction can be converted. So, it's needed to analyze the converting methods in textbooks for getting the implication of teaching in this areas. In this study, I analyzed the Korean and foreign's textbooks. I certified the methods-using addition expression, using part-whole model in the textbooks. For the conceptual understanding, I suggested to use the fusion of the various part-whole fraction models and addition expression more than the algorithm in converting between a mixed number and improper fraction. It's reason that the use of models in converting between a mixed number and improper fraction is important for the relational understanding.

In spite of computer's development, the present state of a lot of electronic documents overflowed it's going to be more difficult to get appropriate information. Therefore it's more important to get meaningful information than to focus on the speed of processing. Semantic web enables and intelligent processing by adding semantic meta data on your web documents. Also as the semantic web grows, the knowledge resource is more important. In this paper, we propose a RDF storage system using relational database model aimed at intelligent processing by adding semantic meta data on your web documents, also a query processor aimed at query processing through the storage system. By using relational model, we could overcome a weakness of object or memory model.

The purpose of this study is to investigate the practical knowledge and implications of special education teachers in the process of pre-learning, a main lesson, and post-learning in field trips in an elementary school special class. To do this, we applied the action research, and conducted a total of 4 sessions, followed by teacher meetings. Participants were a teacher as a researcher, 4 special class students, and 4 class observers. The results of the study are as follows. First, the teacher needs to know the site in advance through preliminary exploration. Second, pre-learning considered about characteristics of students with disabilities improved both learning ability and life function of students. Third, teachers should create appropriate environment for students to participate in the field meaningfully. Fourth, systematic operation of on-site experiential learning improved students' safety consciousness, speaking ability, and self-esteem. Fifth, teachers should keep considering about running student-centered experiential learning. It is also necessary to connect the post-learning with family supports at home.

An educational practice is a communicational course between educator and student with scheme and execution of studying. The communicational contents of the practical course require teaching transmission and recipient process for educator and student as a major knowledges end techniques in order to achieve student's aim. The communication of practical course consists of educators, students, and practical contents, and they also form both meaning objects and mutual relationships for constitution of the practical courses. In order to develop the effective plan for practical process, we have to understand the phenomena of meaning operations which consists in connections of the practical exercise and the meaning object. This study is to approach a phenomenal analysis as respects the meaning operations how forms of tie meaning object exert in the practical course. On the basis of this analysis, we grasp properties of the practical course into the meaning object, and in these connections, suggest the category of cognizance to put execution in the practical course by interpreting factors of the meaning operations.

This paper presents an efficient determination method of thematic roles from syntactic relations using rules and statistical model in Korean language processing. This process is one of the main core of semantic analysis and an important issue to be solved in natural language processing. It is problematic to describe rules for determining thematic roles by only using general linguistic knowledge and experience, since the final result may be different according to the subjective views of researchers, and it is impossible to construct rules to cover all cases. However, our hybrid method is objective and efficient by considering large corpora, which contain practical usages of Korean language, and case frames in the Sejong Electronic Lexicon of Korean, which is being developed by dozens of Korean linguistic researchers. To determine thematic roles more correctly, our system uses syntactic relations, semantic classes, morpheme information, position of double subject. Especially by using semantic classes, we can increase the applicability of our system.

This paper aims to understand the meaning of balanced development among regional economies and its importance in the s0-called knowledge-based economy. It is shown that the balanced allocation of human capital is necessary to achieve the efficient allocation of physical capital among regional economies, which makes the equality of marginal product of capital. And a simulation experiment is conducted to calculate the cost of unbalanced growth. It is shown that balanced growth among regional economies may increase the growth rate of whole national economy while unbalanced growth among them reduce it. The policy implication is that for an any economy to grow at a higher rate, the efficient allocation of physical and human capital both are necessary to have the balanced growth of regional economies in knowledge-based economy.

This study is intended for implementing the system environment that can help integrate and retrieve various types of data in real-time by providing semantic interoperability among distributed heterogeneous information systems. The semantic interoperability is made possible by providing a TMDR(Topicmaps Metadata Registry), a set of ontologies. TMDR, which has been made by combining MDR(MetaData Registry) and TopicMaps and storing them in the database, is able to generate distributed query and provide efficient knowledge. MDR is a metadata management technique for distributed data management. TopicMaps is an ontology representation technique that takes into consideration the hierarchy and association for accessing knowledge data. We have created TMDR, a kind of ontology, that is fit for any system and able to detect and resolve semantic conflicts on the level of data and schema. With this system we propose a query-processing technique to integrate and access heterogeneous information sources. Unlike existing retrieval methods this makes possible efficient retrieval and reasoning by providing association focusing on subjects.

One of core technology in Web 2.0 is tagging, which is applied to multimedia data such as web document of blog, image and video etc widely. But unlike expectation that the tags will be reused in information retrieval and then maximize the retrieval efficiency, unacceptable retrieval results appear owing to toot limitation of tag. In this paper, in the base of preceding research about image retrieval through tag clustering, we design and implement a topic map generation system which is a semantic knowledge system. Finally, tag information in cluster were generated automatically with topics of topic map. The generated topics of topic map are endowed with mean relationship by use of WordNet. Also the topics are endowed with occurrence information suitable for topic pair, and then a topic map with semantic knowledge system can be generated. As the result, the topic map preposed in this paper can be used in not only user's information retrieval demand with semantic navigation but alse convenient and abundant information service.
