  • Objectives: The aim of this study was to investigate the effects of handwriting on the writing assessment, according to whether the handwriting is excellent or bad. Methods: A total of 24 elementary and middle school teachers participated in this study and assessed 6 original writings and 6 transcriptions of the same original writings using the HWP 2007 program. Six writings were collected from elementary students of 4th to 6th grades, 3 of 6 students presented with excellent handwriting and 3 of 6 with bad handwriting. The assessments were done according to the standards of propositional knowledge assessment (You & Jeong, 2008). Results: In the excellent handwritings, the rules of orthography and the contents of introduction of the original writings were scored higher than those in the transcriptions. The difference between transcription and original writing showed minus scores in original writing assessments and plus scores in transcription assessments. In the propositional knowledge score and its subscales scores - content knowledge, text knowledge, language knowledge and text context knowledge -, were differences in transcription assessments significantly higher than those in original writing assessments. Several assessment indices - clarity of the ending, contents of introduction, appropriate contents, rules of orthography, structured composition and various vocabularies showed significantly higher differences in transcription assessments than those in original writing assessments. Conclusions: The excellent handwriting could be assessed high and the bad handwriting could be assessed low. These results suggest that we should consider the effects of handwriting factors on the results of writing assessment and that the transcription could be used for an accurate writing assessment.

  • The diagrammatic language for pathways is widely used for representing systems knowledge as a network of causal relations. Biologists infer and hypothesize with pathways to design experiments and verify models, and to identify potential drug targets. Although there have been many approaches to formalize pathways to simulate a system, reasoning with incomplete and high level knowledge has not been possible. We present a qualitative formalization of a pathway language with incomplete causal descriptions and its translation into propositional temporal logic to automate the reasoning process. Such automation accelerates the identification of drug targets in pathways.

  • The conventional procedure to verify rule bases are corresponding to the propositional logic-level knowledge representation. Building knowledge bases, in real applications, we utilize the predicate logic-level rules. In this paper, we present a verification algorithm of rule bases using Pr/T nets which represent the predicate logic-level rules naturally.

  • This study aimed to explore how to characterize the earth science inquiry in schools in terms of science teaching interaction and constructivist teaching practice. The constructivist teaching practices were analyzed with Reformed Teaching Observation Protocol (RTOP) in three aspects including (1) student oriented class implementation, (2) subject knowledge and representation, and (3) classroom communication. Fourteen earth science classes were observed and scored with RTOP. The class was evaluated to be transitional stage in terms of constructivist teaching, e.g., moving toward student-centered teaching practice. Especially, Korean teachers tend to lean their classes more on propositional knowledge than procedural knowledge. To interpret science teaching interactions, an earth science teacher with a RTOP top rank was selected. Her class was then videotaped for detailed analysis. I adopted the analytical framework of communicative approaches and discourse patterns among the five aspects of interactions presented by Mortimer and Scott (2003). It was found that this earth science teacher used more authoritative patterns than the dialogic. In addition, she used IRE discourse pattern more frequently. Interestingly, teachers interacted with their students more frequently in the form of repeated (or IRE chain pattern), that is IRFRF (teacher initiation-student response-teacher feedback-student response-teacher feedback) in the context of dialogic communicative approaches, while simple IRE occurred in an authoritative approach. In earth science classrooms, typical interaction may well be constructed in the form of IRFRF chains to allow students free conjectures and abduction.

  • The purpose of this study is to clarify the educational literature search methodology objectives and the content structure of a course in bibliography. The content of this study can be summarized as follows: 1. The concept and domain of literature search methodology, which has traditionally gone by the name of a guide to use of literature and library, are described. 2. The need of incorporating the methodology into regular college curriculum was investigated in view of the ideology of college education. 3. The background, process, and current status of offering a course in the methodology as a part of regular college curriculum were examined. 4. The educational objective of a course in the methodology was set at the successful activities in self study, life-long-education, and special topic research. 5. Considering the fact that technical knowledge and propositional knowledge should be realized simultaneously, that educational experience should go hand in hand with materials and library, and that knowledge should be constructed systematically and logically, the content structure of the methodology were divided into the following six categories: a) the significance of the methodology of literature search b) the college library and the activities of literature search c) types and characteristics of materials d) literature search by catalog e) explanation of basic bibliography f) research and literature search

  • In this paper, we evaluate and contrast four neural network rule extraction approaches for credit scoring. Experiments are carried our on three real life credit scoring data sets. Both the continuous and the discretised versions of all data sets are analysed The rule extraction algorithms, Neurolonear, Neurorule. Trepan and Nefclass, have different characteristics, with respect to their perception of the neural network and their way of representing the generated rules or knowledge. It is shown that Neurolinear, Neurorule and Trepan are able to extract very concise rule sets or trees with a high predictive accuracy when compared to classical decision tree(rule) induction algorithms like C4.5(rules). Especially Neurorule extracted easy to understand and powerful propositional if -then rules for all discretised data sets. Hence, the Neurorule algorithm may offer a viable alternative for rule generation and knowledge discovery in the domain of credit scoring.

  • Despite the importance of multinational service ventures' alliances with local firms for CSR engagement, research is little interested in this issue. Because many multinational service ventures have increasingly allied with local firms for their CSR performance, it is important to explain the role of the alliance between a multinational service venture and a local firm. Our study addressed an issue of multinational service ventures' CSR performance through alliances with local firms. Based prominently on the resource-based theory of the firm, the competence-based theory of the firm, and the resource-adavantage theory of competition, we attempted to predict how a multinational service venture can be successful in CSR engagement based on an alliance with a local firm. Our study posited that local firms' CSR knowledge and CSR orientation positively influence multinational service ventures's CSR capabilities. In addition, we posited the positive moderating roles of alliance competence in the relationships between local firms' CSR resources and multinational service ventures' CSR capability. Moreover, our study posited that multinational service ventures' CSR capability is a source of competitive advantage. Finally, we concluded this manuscript with a discussion of scholarly and managerial implications, limitations of the study, and directions for a further study.

  • The purpose of this study is to examine the practice of scientists from the perspective of Ian Hacking's 'creation of phenomena'. Scientific phenomena, according to Hacking, are regular and do not exist in nature without the intervention of scientists or experimental tools. This study tries to derive scientific educational meaning by analyzing the thoughts and episodes of the 'Sontanda (inter-individual variability)' phenomenon experienced by four life scientists. The Sontanda phenomenon is a common term used by scientists to describe phenomena in which findings do not appear consistently even when studies are carried out using the same experimental procedure and materials. The following four educational implications were discovered as a result of the research. First, we confirmed the importance of embodied knowledge, or non-verbal knowledge, which solves issues by making appropriate judgments and reactions at all times, rather than simply becoming accustomed to the experimental method. This argues that propositional knowledge and non-verbal knowledge should be handled equally in order to provide students with a practical scientific inquiry. Second, we tried to reconsider the picture of the experiment. The phenomenon revealed in the interviews of scientists is rare, and it takes a long time to stabilize the phenomenon. On the other hand, the image of school experiments is always positive and consistent, necessitating a shift in perspective. Third, the precise meaning of scientific practice could be confirmed. This study confirms that scientists use their knowledge effectively in line with the circumstances, and we examined strategies to apply scientific practice to school instruction based on this. Finally, by provoking uncertainty, the Sontanda phenomena may give students with an opportunity to engage in meaningful scientific involvement. By breaking away from the cookbook experiment, this study expects school experimental education to help in efforts to experience scientific practice.

  • Since sentences are the basic propositional units of text, their themes would be helpful for various tasks that require knowledge about the semantic content of text. Despite the importance of determining the theme of a sentence, however, few studies have investigated the problem of automatically assigning the theme to a sentence. Therefore, we propose a sentence theme allocation scheme based on the head-driven patterns of sentences in encyclopedia. In a serious of experiments using Dusan Dong-A encyclopedia, the proposed method outperformed the baseline of the theme allocation performance. The head-driven pattern 4, which is reconfigured based on the predicate, showed superior performance in the theme allocation with the average F-score of $98.96\%$ for the training data, and $88.57\%$ for the test data.

  • In this paper, a database interface system with natural language dialogue is designed and implemented. The system is made up of language analysis, context processing, dialogue processing and DB processing unit. The method for classifying and processing an undefined word in language analysis is proposed. It reduces the dictionary size, which gives difficulties in DB Interface. And the current DB Interfaces dealt with an input utterance independently. But the system in this paper provides a user with the interface environment in which he or she can have a continuous conversation with the system and retrieve DB information. Thus in this paper, speech acts which include user's inattentions well as propositional contents are defined, and user action hierarchical model for library DB retrieval is constructed. And the system uses the defined knowledge to recognize-user's plan, effectively understanding and managing the ongoing dialogue. And the system is implemented in the domain of library database in order to prove the proposed methods in this paper.
