  • The present study tested the hypothesis that adolescents' performance on scientific reasoning tasks and their ability to change theoretical concepts during instruction are mediated by prefrontal-cognitive functions, such as planning and inhibiting. Subjects sampled from four Korean secondary schools were administered a test of scientific reasoning ability and tests of the prefrontal lobe functions. A series of lessons on theoretical concepts was also administered. Subjects' performance on the test of scientific reasoning and pre- to posttest gains in the concept test were used as dependent variables. This study found that students' planning and inhibiting abilities were highly correlated with and they significantly predicted their scientific reasoning ability and conceptual gains. Further, principal component analysis showed prefrontal lobe functions were categorized into two main components. Component 1, which was loaded by planning and working memory functions, was termed as the representing process. Component 2, which was loaded primarily by the inhibiting functions, was termed as the inhibiting process. Scientific reasoning and conceptual change were also linked to these two components, indicating that these cognitive processes are mediated by both representing and inhibiting processes.

  • The purpose of this study was to investigate the effect of case-based learning program on three elementary students' scientific problem solving and attitudes in science class. For this study, case-based learning program was designed for bridging students' scientific knowledge and their personal experiences in real life through 4 stages: understanding the problem, planning for problem solving, conducting problem solving, and making conclusion. This study was carried out through 17 lessons of 4th grade for 6 weeks. The data was collected through close observation on three students in two groups in a class. The results include that cased-based learning program showed overall positive effects on the elementary students' scientific problem solving and attitudes in class. In particular, it turned out that the continuous emphasis of real world examples in case-based learning had powerful impacts on students' problem solving abtsity, motivation, and participation in classroom activities. The key factors to successful problem solving in school science was discussed.

  • When planning lessons and developing materials about mathematical teaching and learning, we should condignly change and reconstruct contents and orders in light of ranks and connections between subject materials. Moreover teachers should teach mathematical concepts so that students might understand then not only independently and disjunctively but also relationally and reflectively. For this, teachers have to prepare thoroughly. By analyzing advanced research for mathematical connections, this study categorizes them according to two conditions: internal-external and content-formality. Through this, tactical aspect similarity and indistinguishability between mathematical external connections and mathematical internal connections have been identified. Based upon this fact, this study proposed the principles and the examples of tactical aspect on mathematical Internal Connetions.

  • We have developed a tool for annotation of electronic health record (EHR) data. Currently we are in the process of manually annotating a corpus of Norwegian general practitioners' EHRs with mainly linguistic information. The purpose of this project is to attain a linguistically annotated corpus of patient histories from general practice. This corpus will be put to future use in medical language processing and information extraction applications. The paper outlines some of our practical experiences from developing such a corpus and, in particular, the effects of semi-automated annotation. We have also done some preliminary experiments with part-of-speech tagging based on our corpus. The results indicated that relevant training data from the clinical domain gives better results for the tagging task in this domain than training the tagger on a corpus form a more general domain. We are planning to expand the corpus annotations with medical information at a later stage.

  • Many countries have implemented EA as a core tool for planning and managing IT resources. Due to its importance, there have been many studies for the successful implementation of EA. However because most previous studies simply focused on either a certain time horizon as a cross sectional study or a list of success factors, they failed to raise fundamental issues investigating inherent difficulties or efforts to overcome. This research conducted a case study based on interviews with EA experts and derived five practical guidelines for the successful EA implementation. Simultaneously we propose a future research model for an empirical validation based on current findings.

  • This study was conducted as a part of the project to establish professional development system(PDS) for teachers in Korea. This study aimed to provide a case of running a professional learning community(PLC) of teachers in science education based on the collaboration of a national university of education and its affiliated elementary school, in search of learning by participants and implications for professional development of teachers as well as for science teaching in elementary schools. Teachers and researchers who participated in the PLC were able to accumulate meaningful experiences through 11 rounds of meetings. It was not easy to secure enough time for meetings, but they were able to boost their self-confidence for science teaching and enhance the quality of lessons through these gatherings. Participating teachers had a chance to share instructional design, planning, strategies and practices, which include cases of guiding free-choice research activities among students, thereby to be motivated for improved science teaching for the future. The researcher participating in this PLC was also able to understand the identity of an elementary school, especially the affiliated school, and identify the reality and difficulties related to science teaching in schools. Experiences of participating in PLC are expected to help improve the quality of science teaching in affiliated elementary school and pre-service teacher education of the university.

  • Most of the Indian contractors are not well equipped to handle the growing demand of infrastructure development; hence construction projects frequently run in to time and cost overruns, disputes and quality issues. This study aims to improve the construction industry in India by implementing lean principles to eliminate non-value adding activities (wastes). The purpose of this study is to 1) identify the wastes and their sources affecting the construction process, and 2) to identify problems and document lessons by applying a Last Planner System (LPS) to a sample project. First, the researchers identified that Delays, Rework, and Interruptions were the most critical wastes affecting the construction process and Poor management control, Poor Planning and Shortage of Resources were the major sources of the above mentioned wastes. Second, the researchers report the Percent of Planned Complete (PPC) analysis results and experienced problems after implementation of LPS at the sample project. It was observed that much more improvement could have been achieved if there was consensus between the owners and the contractor on the implementation of the LPS in its entirety. Some of the problems experienced in the implementation of the LPS like lack of scheduling, resource and material shortage were found to be similar to those in developed countries.

  • Client organization inadequate project planning before awarding the contract and insufficient monitoring and control system among the parties involved create severe problems. Ultimately, large-scale projects go beyond the expected cost and time control limits. This paper discusses the major issues involved with a large-scale Hydropower Project in Pakistan Public Sector environment. The latest approved Baseline Plan of project was reviewed and analyzed using Variance Analysis and Trend Analysis techniques in Primavera project management software to assess the efforts made of the parties involved. It was found that Project is 202% Cost overrun and 25% time delays from original contract award. After analysis of baseline plan and quantification of various variance issues in impacted activities, the questionnaire survey was conducted to identify the impact of causative factors. There were almost 17 most significant causative factors identified among 60 identified factors and responsibilities are assigned accordingly. At the end recommendations are made for strategic decisions as lessons learned during project evaluation.

  • Any organization's Six Sigma program may be at high risk without heeding the lessons learned from the past and that tries to operate without a robust business foundation. A foundation that preferably should consist of stepping-stones such as a 5-S house-keeping program, an effective Integrated Management System (IMS), which includes a strong focus on planning for quality to fully capture the Voice of the Customer (VOC), and an organization-wide training scheme, as well as a reliable Cost of Poor Quality (COPQ) system. That's the best advise I can give to any organization that wishes to embark on a Six Sigma improvement program and hope to be successful. The paper will elaborate on the above issues and provide suggested solutions based on the review of published historical information and the experiences encountered over the last four decades by the author, as a quality practitioner and consultant, in industries that produced safety-critical product. This author maintains that few fundamentally new or useful things have been created in the field of Quality during the last couple of decades. Nevertheless, this paper deliberates on a number of relatively “newer” issues including the concept of “three types of customers”, the CTC, “Critical To Customer” term, the eight Quality Management Principles of the new ISO 9000 family, the growth of industry-specific standards, the adoption of Integrated Management Systems, the rebirth of AS2561 COQ standard, the spread of Six Sigma as well as related ASQ certification and the need for a robust business foundation to ensure Six Sigma survival.

  • According to Kenneth Frampton, the modern architecture starts to be recognized as the poetics of construction and lays a great weight in its value on the technology of making forms and the inherent meaning in the tectonics. The tectonic connotes not only the technological construction of the architecture but also ontological details as the joint of material and texture. The works of Carlo Scarpa are examples to prove the way how the ontological meanings are exposed in the tectonic form of architecture. The purpose of this study was to analyze the connections between Carlo Scarpa's architectural thoughts and visual logic(schemata) from the characteristic of details in his work during the 1950s to 1970s. Through the analysis, the Italian tradition in the architecture is reinterpreted through isolation and break of recollected montages. Carlo Scarpa makes spatial fragments and aspects of reinterpreting in surroundings and situation with the architectural place in Venezia. As a result, the unique details of his craftsmanship provide lessons on how to reinterpret the traditional architecture. In conclusion, Carlo Scarpa's architecture emphasizes the passage of its perceptive experience aspects as a dis-joint of tectonic forms. It may imply the significance of his philosophical approach, especially to the ontological architecture and tectonics.
