  • The purpose of this qualitative case study was to investigate the 'structure' of an elementary school teacher's practical knowledge concerning science experiment lessons. A female elementary teacher in the early career years participated in the study, and video recordings of her science experiment lessons as well as audio-taped interviews with her were analyzed by means of Elbaz's framework. The teacher expressed six images of science experiment lessons: 'Science is difficult', 'Experiments are dangerous', 'Experiments are accurate', 'A science experiment takes a long time', 'Science experiments are interesting', and 'Children are little scientists.' These images were supported by several principles and rules, most of which were clearly described. Among the images, principles, and rules, there were complex relationships with some working in synergy and some conflicting. In case of the image 'Children are little scientists', its subordinate principles and rules were not fully realized in the classroom. Implications for science teaching reform and science education research were discussed.

  • Listening has been a neglected research area despite the crucial role it plays. The present investigation was aimed at examining how the provision of topical knowledge and learners' listening proficiency level affect learners' listening performance under four different preparatory activity conditions: topical knowledge, vocabulary list, language structure, and no activity. A total of 134 participants, assigned to the four different activity groups, took part in the study. The results revealed that the learners who were provided with topical knowledge before listening performed significantly better than the other learners, followed by the vocabulary list group and language structure group, which might be attributed to the activation of their content schemata. The learners who did not perform any preparatory activities achieved the lowest scores. When it comes to the impact of listening proficiency, it was revealed that learners' proficiency level had a significant influence on learners' listening performance, and there was a significant interaction between the learners' level of listening proficiency and preparatory activity. Providing relevant knowledge was effective for both higher level and lower level learners, whereas teaching vocabulary before listening was effective for higher level learners but was not for lower level ones. Based on the results, some pedagogical implications and suggestions for future research were discussed.

  • Given the variety of approaches to mapping the universe of knowledge that have been presented and discussed in the literature, the purpose of this paper is to systematize their main principles and their applications in the major general modern library classification schemes. We conducted an analysis of the literature on classification and the main classification systems, namely Dewey/Universal Decimal Classification, Cutter's Expansive Classification, Subject Classification of J.D. Brown, Colon Classification, Library of Congress Classification, Bibliographic Classification, Rider's International Classification, Bibliothecal Bibliographic Klassification (BBK), and Broad System of Ordering (BSO). We conclude that the arrangement of the main classes can be done following four principles that are not mutually exclusive: ideological principle, social purpose principle, scientific order, and division by discipline. The paper provides examples and analysis of each system. We also conclude that as knowledge is ever-changing, classifications also change and present a different structure of knowledge depending upon the society and time of their design.

  • In this study, we investigate the possibility of deploying a recently emerging Internet-based technology, called Web log or Blog, to address the problems of knowledge transfer and sharing, particularly in the case of tacit knowledge. We examined the use practice of four blogs and then identified several properties relevant to knowledge transfer and sharing. They include the specific style of blog format, content ownership attribution, posted article organization, communication tools and method, news feed function, and various links from/to outside websites. These features were argued to facilitate knowledge transfer and sharing. In particular, we discussed a great deal about the structure of comments and links as tools for collaboration and idea sharing, which enables the knowledge conversion processes (socialization, externalization, combination, and internalization), We then provide several guidelines to develop blogs as a knowledge management tool.

  • 시공단계의 경험 및 지식을 반영한 설계 결과물은 시공 효율성을 향상시키고 설계변경을 최소화하여 프로젝트의 낭비요인 제거와 전체적인 생산성 향상을 가능하게 해준다. 설계자가 설계단계에서 시공단계의 경험 및 지식을 효과적으로 활용하기 위해서는, 설계과정에서 필요한 시공성 지식을 필요한 시점에 활용할 수 있어야 한다. 설계단계에서 시공성 지식의 효과적인 활용을 위한 기존의 접근방법은 체크리스트와 같이 설계단계 별로 활용되는 시공성 지식의 구조화에 초점을 맞추고, 설계의 사결정과정의 기본단위가 되는 액티비티 수준에서 시공성 지식의 활용시점에 대한 고려가 부족하다. 하지만 적절하지 않은 시점에서 고려된 시공성 지식은 설계자에게 불필요한 재작업을 야기해 설계생산성을 저하시키는 문제를 발생시킬 수 있다. 이러한 비효율적인 정보교환을 최소화하기 위해서는, 설계 프로세스 상에서 정보흐름에 중점을 둔 설계관리를 통해 각 시공성 지식들을 요구하는 설계 액티비티가 무엇인지를 파악해야 한다. 이에 본 연구는 Dependency Structure Matrix(DSM)를 이용하여 설계의사결정과정의 기본단위가 되는 설계 익티비티와 설계과정에서 고려해야 하는 시공성 지식간의 상호관계를 고려한 정보흐름기반의 설계프로세스관리를 제안한다. 이는 설계프로세스관리를 설계단계에서의 단순한 설계검토보다 한 단계 높은, 건설프로젝트 전 과정과 연계된 포괄적인 관리활동으로 발전시켜 건설생산합리화에 크게 기여할 수 있으리라 예상된다.

  • A prototype integrated system and its theories for distributed SISO control structure synthesis of complete chemical plants is developed. The scope of this work includes control structure synthesis not only of simple units with unspecified control loops but also of the complex process at preliminary and basic design stage. Hierarchical approach and dual-decomposition strategy (that is multi-layer decomposition and multi-echelon decomposition) is applied to this system. Because automatic control structure synthesis of complex plants is a problem defined as a series of knowledge-intensive tasks within multiple spaces, the established methodology is complemented by not only techniques from knowledge-based expert systems but also shortcut and rigorous control theories. This system is used for education of control designers, process engineers, operators and students as well as for operability studying, in-line and on-line process control structure synthesis.

  • This study investigated the effects of variations in the kinetic structure on science knowledge acquisition. According to the rationale of the kinetic structure theory, a communication having high structrue would facilitate greater knowledge acquisition than a presentation with low structure. To testify that hypothesis, a modified non-equivalent pretest posttest control group design was used. Four 10th grade classes (2 classes for each sex) were selected. On the topic of human digestive system, two tape recorded lessons differing in kinetic structure were developed. On n of two was high structure ($\bar{B}_{1}$=0.56), and the other was low structrue ($\bar{B}_{1}$=0.99) Results indicated that the high structure lesson did not show significantly higher score than the low structrue lesson(F=2.225, P<0.137). But when the data were analyzed by sex, only boy students showed the result that the high structure lesson had significantly higher score than the low structure lesson (F=4.785, P<0.009). The results of this study suggest that a high Structure communication will facilitate the science achievement in the case of boy students.

  • As the role of information collection becomes increasingly important in the enormous data environment, there is growing demand for more intelligent information technologies for managing complex data. On the other hand, it is difficult to find a solution because of the data complexity and big scaled amount. Accordingly, there is a need for a special intelligent knowledge base frame that can be operated by itself flexibly. In this paper, by adopting switching function for signal transmission in the synapse of the human brain, I/E selective activation based knowledge reconfiguring mechanism is proposed for building more intelligent information management system. In particular, knowledge network design, a special knowledge node structure, Type definition, I/E gauge definition and I/E matching scheme are provided. Using these concepts, the proposed system makes the functions of activation by I/E Gauge, selection and reconfiguration. In a more efficient manner, the routing and reasoning process was performed based on the knowledge reconfiguration network. In the experiments, the process of selection by I/E matching, knowledge reconfiguration and routing & reasoning results are described.
