The purpose of this study was to explore how an elementary school teacher developed PCK by utilizing her knowledge domains in teaching practice, regarding the specific science topic of 'animals:' A case study approach was adopted with the participation of a 1st grade teacher, in a poor urban neighborhood elementary school in NYC. Data was collected through interview and the participant observation method in order to investigate: a) the teacher's existing knowledge base in terms of subject matter knowledge, pedagogical knowledge and contextual knowledge; b) how she develops PCK during classroom practice, centering on the relationship between knowledge domains. The findings illustrate the ways in which the three knowledge domains are closely related and developed as PCK through the whole teaching process. In particular, the findings indicate that the teacher's contextual knowledge plays a critical role in shaping and developing PCK. Before instruction, her contextual knowledge regarding the administrative policies and the school test system in the district enabled her to make decisions and plans about teaching science. During classroom teaching, her knowledge of students' sociocultural backgrounds and living conditions in the urban setting helped her to identify specific teaching strategies and resources suitable to the students' needs and interests. The study results imply that science instruction can be more feasible in meeting the demands of particular groups of students if teachers make an effort to become knowledgeable about their own teaching context and utilize it in developing their PCK.

Over the last few years knowledge management has become more and more impotant part of the in healthcare practices. Therefore the healthcare organisatiions have also begun to apply knowlege management strategies. To address this issue of the lack of true knowledge management in healthcare enterprises, we propose a framework for common Healthcare Knowledge Management. This framework is made up of two suites of applications and services, i.e. the intelligent agent-based knowledge management application suite and the strategic visualisation, planning and coalition formation service suite.

Purpose: The purpose of this study was to analyze papers on child rearing in Korea and to suggest future research and nursing practice directions for child rearing. Methods: An on-line search via 5 web sites yielded 201 research papers. The analysis of key concepts was based on the attributes of parenting and type of knowledge held by the parents. Results: The research papers found in the search were 27.3% experimental and 72.7% non-experimental. Among the participants, 77.0% of parents raising the child were mothers and the children were mostly young children under the age of one year. Types of knowledge related to child rearing varied widely, but explanatory knowledge (55.2%) was the most common, followed by prescriptive knowledge (30.0%) and descriptive knowledge (14.8%). For attributes of parenting, reaction to parenting (49.9%) followed by parenting behavior/practice (43.1%) was most common. Conclusion: Findings of this study indicate that further research is necessary regarding fathers and surrogate caregivers and on prescriptive knowledge for health promotion of children at different developmental stages. Also the results suggest a need for research toward developing child care policies.

In order to investigate the composition and characteristics of instructional objectives in a teaching-learning material for gifted elementary students in science, 217 instructional objectives across 13 themes in 4 areas of 'energy','materials', 'life' and 'earth' were analyzed by Bloom's revised taxonomy of educational objectives. Four types of factual, conceptual, procedural and meta-cognitive knowledge in knowledge dimension were all comprised in the objectives. Conceptual knowledge was primary constituent of the objectives and the proportion of factual knowledge was the least. On the other hand, all 6 categories of 'remember', 'understand', 'apply', 'analyze', 'evaluate' and 'create' in cognitive process dimension were also comprised in the objectives. The category of 'understand' was primary constituent and that of 'remember' was the least one. While conceptual knowledge in knowledge dimension was primary constituent of the objectives in 'energy', 'materials' and 'earth' areas, procedural knowledge was the most objectives in 'life' area. The least type of knowledge was factual knowledge in all 4 areas. In cognitive process dimension, the category of 'understand' was primary constituent and that of 'remember' was the least one in all 4 areas. In conclusion, it was showed that the instructional objectives in the teaching-learning material reflected the characteristics of educational objectives for gifted students in science.

KBANN (knowledge-based artificial neural network) combining the analytical learning and the inductive learning has been shown to be more effective than other machine learning models. However KBANN doesn't have the theory refinement ability because the topology of network can't be altered dynamically. Although TopGen was proposed to extend the ability of KABNN in this respect, it also had some defects. The algorithms which could solve this TopGen's defects, enabling the refinement of theory, by extending KBANN, are designed.

As knowledge management is recognized as an important competency of organizations, organizations are continuously investing in knowledge management policies and technologies. Knowledge management preemptively requires employees to share knowledge, but sharing activities for continuous knowledge management have not been performed. The purpose of this study is to verify the effect of the organization's mutual exchange efforts through collaborative communication on the knowledge sharing intention of its employees. The study surveyed workers of organizations that operate knowledge management policies and verified the research hypothesis by applying 326 samples to structural equation modeling. As a result of the analysis, factors of collaborative communication(rationality, reciprocal feedback, formality) had a positive effect on the intention to share knowledge, and task interdependence and territoriality had a moderating effect on the relationship between collaborative communication and intention to share knowledge. The study has implications in terms of suggesting an activity strategy that an organization should pursue to improve knowledge sharing among its employees.
