This study undertook a methodological investigation on previous research that had proposed alternative methods for analyzing argumentative discourse in science classes in terms of collaborative construction and epistemic enactments of argumentation. The study also proposed a new way of analyzing argumentation discourse based on the achievements and limitations of previous research. The new method was applied to actual argumentation discourse episodes to examine its feasibility. For these purposes, we chose the studies employing Toulmin's argument layout, seeking for a method to analyze comprehensively the structure, content, and justification of arguments, or emphasizing evidence-based reasoning processes of argumentation discourse. In addition, we contrived an alternative method of analyzing argumentative discourse, Discourse Register on the Evidence-Explanation Continuum (DREEC), and applied DREEC to an argumentative discourse episode that occurred in an actual science classroom. The advanced methods of analyzing argumentative discourse used in previous research usually examined argument structure by the presence and absence of the elements of Toulmin's argument layout or its extension. Those methods, however, had some problems in describing and comparing the quality of argumentation based on the justification and epistemic enactments of the arguments, while they could analyze and compare argumentative discourse quantitatively. Also, those methods had limitations on showing participants' collaborative construction during the argumentative discourse. In contrast, DREEC could describe collaborative construction through the relationships between THEMEs and RHEMEs and the links of data, evidence, pattern, and explanation in the discourse, as well as the justification of arguments based on the flow of epistemic enactments of the argumentative discourse.

Research is being made for users' convenient access to services such as personalized data and contents services. The use of information and the fusion of services in various devices and terminals suggest the necessity to know what personalization mechanism is used to provide high quality contents at a time and place desired by users. Existing mechanisms are not easy to be handled by other service providers because each service provider has different preference and personal information, and are very inconvenient because service users have to set up and manage by themselves. Thus, the present paper proposes a Semantic User Profiles Manager based on OSGi, middleware for the provision and extension of semantic services, in order to manage users' profiles dynamically regardless of service provider. In addition, this paper defines a personalized semantic profile that enables user profiling, ontological domain modeling and semantic reasoning. In order to test the validity of this paper, we implemented semantic profiles into a bundle running based on OSGi. When users enter the range of the service area and use various devices, the semantic service matches in correspondence with semantic user profiles. The proposed system can easily extend the matching of services to user profiles and matching between user profiles or between services.

The objectives of the study are to look into the fisheries processing industry, analyze problems the industry has, and develop strategies for the industry to take care of the problems. The study was performed in two different dimensions : industry level and firm level. Nevertheless, the study focused on the following main problem areas raw material, production, technology development, internationalization, and managerial performance. The secondary data were utilized to analyze problems at the industry level, For analyzing the firm level situation, an empirical study by using a mail survey with a questionnaire was accomplished. The main problems found were as follows : First, difficulty in procuring raw material was the most serious and main problem. It was caused, externally, by the announcement of 200 nautical miles by most of fishery abundant countries and, internally, by drying fishery resources in the nation's coastal areas ; Second, the rate of fishery processing has been continuously increased and the degree of the processing has also been sophisticated, which implies the pattern of demand for the fishery has been changing widely and deeply. The industry, however, seemed to be unable to meet the consumers' satisfaction ; Third, with the importance of technology for ensuring the changing demands in the fishery processing industry, there has been little effort in research and development both at industry level and at the firm level ; Next, the industry has mainly involved in exporting in association with internationalization. Not to mention about foreign direct investment, technology transfer was not active ; Finaliy, most of firms were densely located in a few areas. The managerical performance in terms of main financial ratios still needs to be improved. Thus, strategies, which would take care of the repective problems, were developed. At industry level, the strategies were developed by reasoning mostly based on the findings from the literature survey. A scheme for internationalization of the firms was suggested. This was made by extracting the factors which would differentiate the firms' internationalization stages. In order to achieve this analysis, discriminant approach was employed. Despite the utility of the findings, it was mostly emphasized that harmonious efforts among government, the industry supporting institutions such as banks, and firms are needed for the successful operation of the strategies. Also, a list of areas for further study was provided especially in relation to the validity threatening parts of the study.

This paper makes a preparatory attempt to reconstruct 'the Korean Science Culture' toward which I think the Koreans should direct and orient themselves rather than describe the history of the science culture in Korea. This task requires us to define 'science culture.' So I propose, based on the definitions of science culture so far made, to consider the model of 'Humanized Science Culture' as a regulating ideal of the Korean Science Culture. To support the model, analyzing the concept of 'science literacy' of the 2061 Project, I posit the model of KDSC (Korean Designer of Science Culture) as the Koreans who will actually come to design the Korean Science Culture. KDSC refers to 'a reasonable man' who will represent a desirable Korean, rather than to a natural Korean. Then I spell out the conditions of becoming a KDSC and scrutinize the philosophical backbones of those conditions. Finally, I make a few suggestions for developing a program of designing and implementing the Korean Science Culture from the viewpoint of a model of KDSC.

The purpose of this study was the investigation of theoretical and empirical relationships between Piagetian and psychometric assessments of intelligence. Specifically, the factor structure of Piagetian-type scales, the relationship between Piagetian scales and psychometric intelligence tests, and differences in the factor structure of Piagetian and psychometric assessments of intelligence were studied. The subjects of this stuby were 70 children (35 boys and 35 girls) in the 1st grade of an elementary school in Seoul The Piagetian-type scales and the K-WISC were administered individually, and the General Intelligence Test was administered to groups of children. Statistical analysis of the obtained data consisted of the SPSS Computer program including factor analysis and Pearson's product moment correlation coefficient. The Piagetian-type scales were found to consist of three factors, which accounted for 55 percent of the total common-factor variance. Factor-I was a factor indicating "conservation". Factor-II was a factor indicating "moral judgements". Factor-III was a factor indicating "classification and identity". Correlations between subtests of psychometric tests and Piagetian scales were relatively low or moderate. Relations between IQs assessed by the psychometric tests and Piagetian scales were also relativeyly low or moderate. Eight factors were extracted from the joint factor analysis of psychometric intelligence tests and Piagetian scales, and they accounted for 67 percent of the total common-factor variance. Factors-I, II, III, and V consisted of subtests of psychometric assessments, and Factors-IV, VI, VII and VIII were composed of Piagetian scales. Factor-I was a factor for "reasoning ability based upon language". Factor-II was a factor for "performance ability". Factor-III was a factor for "grouping ability". Factor-IV was a factor for "conservation". Factor-V was a factor indicating "symbol and language usage ability". Factor- VI was a factor indicating "moral judgments". Factor-VII was a factor indicating "length consevation". Factor-VIII was a factor indicating "classification and identity".

The objective of this paper is to develop an intelligent decision support system that is able to advise disaster countermeasures and degree of incidents on the basis of the collected and analyzed signs of disasters. The concepts derived from ontology, text mining and case-based reasoning are adapted to design the system. The functions of this system include term-document matrix, frequency normalization, confidency, association rules, and criteria for judgment. The collected qualitative data from signs of new incidents are processed by those functions and are finally compared and reasoned to past similar disaster cases. The system provides the varying degrees of how dangerous the new signs of disasters are and the few countermeasures to the disaster for the manager of disaster management. The system will be helpful for the decision-maker to make a judgment about how much dangerous the signs of disaster are and to carry out specific kinds of countermeasures on the disaster in advance. As a result, the disaster will be prevented.

Models for human cognition currently discussed in cognitive science cannot be appropriate ones. The symbolic model of the traditional artificial intelligence works for reasoning and problem-solving tasks, but doesn't fit for pattern recognition such as letter/sound cognition. Connectionism shows the contrary phenomena to those of the traditional artificial intelligence. Connectionist systems has been shown to be very strong in the tasks of pattern recognition but weak in most of logical tasks. Brooks' situated action theory denies the. notion of representation which is presupposed in both the traditional artificial intelligence and connectionism and suggests a subsumption model which is based on perceptions coming from real world. However, situated action theory hasn't also been well applied to human cognition so far. In emphasizing those characteristics of models I refer those models 'left-brain model', 'right-brain model', and 'robot model' respectively. After I examine those models in terms of substantial items of cognitions- mental state, mental procedure, basic element of cognition, rule of cognition, appropriate level of analysis, architecture of cognition, I draw three arguments of embodiment. I suggest a way of unifying those existing models by examining their theoretical compatability which is found in those arguments.

The purpose of this study was to develop a school violence prevention program featuring the Practical Action Teaching Model(hereafter, PATM) for middle school students to prevent school violence by Home Economics Education. To accomplish this purpose, the processes of analysis, design, development, and evaluation based on ADDIE were conducted. The validity of the program was evaluated twice by Home Economics education experts(36 experts for the first group and 10 experts for the second group) and the contents of the program were modified according to the comments from the evaluators. The school violence prevention program in Home Economics classes consisted of 5 topics such as changing perception on school violence, enhancing self-esteem, relating with others, practicing consideration and sharing, and strengthening the will of preventing school violence. Twenty-four units were developed with 7 practical problems(What should I do to make friends to help with each other?, What should I do to establish positive self-concept?, What should I do to communicate to build good relationship?, What should I do to solve the conflicts peacefully?, What should I do to practice consideration and sharing in food consumption?, and What should I do to practice consideration and sharing in clothing?) in 5 topic areas. Teaching-learning plans included four steps such as problem perception, practical reasoning, action, and evaluation that comprise PATM to solve the practical problems. Every step of the teaching-learning plan consisted of questions for practical reasoning and activity assignments. Materials for students and teachers were developed. Materials for students comprised 80 pieces in total including student activity, reading, movie, and clips to make students enhance understanding and interest. Materials for teachers comprised 35 pieces in total such as rationales, newspaper articles, and movies that make teachers that lesson teaching loads and were helpful for teachers. The PATM was incorporated into developing the program and a Likert-scale was used to assess usefulness, applicability, appropriateness, fidelity, substantiality, and validity of this program. This program gained more than 4.00 on a 1-5 Likert scale. This result indicated that program is expected to be effective and useful to school violence prevention.

Semantically-operated services, which is different from Web services or semantic Web services with semantic markup, can be defined as the services providing search function or reasoning function using ontologies. It performs a pre-defined task by exploiting URI, ontology classes, and ontology properties. This study introduces a method for pipelining semantically-operated services based on a semantic broker which refers to ontologies and service description stored in a service manager and invokes by user constraints. The constraints consist of input instances, an output class, a visualization type, service names, and properties. This method provides automatically-generated service pipelines including composit services and a simple workflow to the user. The pipelines provided by the semantic broker can be executed in a fully-automatic manner to find a set of meaningful semantic pipelines. After all, this study would epochally contribute to develop a portal service by ways of supporting human service planners who want to find specific composit services pipelined from distributed semantically-operated services.

The purpose of this study is to find out the philosophy embedded in the newly revised 2007 Home Economics curriculum. Furthermore, it analyses the current situation and future tasks of textbooks in view of that philosophy. With this analysis it tries to give alternative teaching-learning strategies for making the best use of the existing textbooks. This study deals with the newly revised 2007 Home Economics curriculum. It also analyses the twelve sorts of textbooks for the first grade students in secondary schools, which are supposed to be based on that curriculum. As a research method this study takes a qualitative approach. As follows are the results of this study. First, in the character and objectives of the curriculum is embedded the critical science perspective of Home Economics curriculum. Second, the current situation and future tasks of the textbooks are analysed with the criteria by Yang, mi-kyung about textbook construction. And we have ascertained the following problems. The current textbooks are not well designed so that teachers have the appropriate orientation, encourage students to nurture the critical thinking abilities, and urge students to employ practical reasoning in the context of society, history and culture. Third, this study proposes five alternative teaching-learning strategies for making the best use of the current textbooks in order to tackle the above-mentioned problems.
