  • Selecting an appropriate formwork to fit the construction of a high-rise building is an important factor that can influence the success or failure of a construction. Currently, however, the reality is that in domestic high-rise building construction, the selection of an appropriate formwork with consideration of the characteristics of the formwork has not been done in a reasonable manner. To select formwork in a systematic and reasonable fashion, comprehensive consideration is required that must not only include the aspect of construction costs, but also air, quality, safety, and environmental issues. Therefore, this study aims to rationalize the selection process of formwork by applying the scientific method of Analytic Hierarchy Process (AHP) to the selection process of formwork, in terms of construction costs, quality and safety. To do this, the researcher investigated the current status of formwork being used in high-rise residential building construction. Then, based on the results of this investigation, the researcher selected an alternative for the formwork, and taking construction experts as the subjects of this study, conducted a survey on the applicability of the formwork as well as the priority of management thereof when selecting formwork. It is judged that the results of this research will contribute a more scientific and reasonable decision-making process than the existing non-scientific method in selecting formwork for high-rise residential building construction.

  • Research Projects allow students to experience of scientific research by conducting experiments on specific scientific subjects and writing reports. The process of research begins as students find and propose research questions and its importance has been consistently emphasized. In this study, we developed various strategies to support students to draw research questions and applied to each phase. We analyzed how students' research questions were developed at different phases. The program consists of five phases, such as (1) Exploration, (2) Literature Review and Data Collection, (3) Modification and Extension, (4) Sharing and Evaluation, (5) Final Selection and Research Plan. The program was applied to high school Research Project for 12 hours. A total of 13 students were divided into four groups of 3-4 students and conducted researches. The results of each student's research process and final research plans were then collected and analyzed. The overall quality of research questions produced by the students showed improvement in each phase. Each strategy improved in various aspects of the research questions at each level. Students were able to find their own area of interest in the 'Exploration' phase and then they began to suggest verifiable plans in the 'Literature and Data Collection' phase. They were able to find a variety of variables under the 'Modification and Extension' phase, whereas the precision of research questions improved in the 'Sharing and Evaluation' and the 'Final Selection and Research Plan' phase.

  • This study is a case study of the process of emerging for creative products to lead world science and technology. The aim of the study is to understand the emerging process of scientific creative products, and is to provide the direction of gifted education that discovers and trains globally competitive science talents through this. To discuss the emerging process of creative products, this study has academically discussed the creativity of the complexity of dealing with theory of evolution, the real life settings, and self-organization of experience etc., and has methodologically adopted the qualitative research method through a case study to look at the structures and processes. Data collection has been formed through a discussion with 12 Korean scientists who have created selected creative products, greatly contributed for the world science and technology(12 areas). The analysis has been carried out by the latter part positivist methods. As a result, the emerging process of creative products in the field of science and technology were separated into four steps: (1)the foundation stage of knowledge, (2)the exploration stage of knowledge, (3)the construction stage of knowledge, and (4)the emerging stage of knowledge. Each stage has been revealed growing up through the macro-system and the self-organization of each micro-systems.

  • The very fact that so many of us are here to participate in this conference on Operations Research is an indicator of the importance we attach to this relatively new and still expanding field. All of us recognize that Operations Research techniques are especially useful tools in problem solving in business, Government and the military. A discussion of the role of Operations Research and the related field of Systems Analysis in national defense policy and programming decision processes seems especially appropriate at the opening session of this conference, As you know, Operations Research as an organized form of research first found application in the review of individual military weapons systems and their effectiveness just over forty years ago. From that relatively narrow beginning has evolved a discipline whose future exploitation and utility you will explore over the next several days. I plan to review very briefly the historical development of Operations Research and Systems Analysis as tools in the defense decision-making process. Then, I will give you an overview of their application to today's military and defense problem solving by discussing the use of these techniques at the headquarters level by the United States Navy, Obviously, in such a brief period, I cannot cover all applications, specific techniques, or all of the groups involved in such a complex process. A review of the historical development of Operations Research/Systems Analysts reveals that the use of the basic concepts of Operations Research is not new; it originated with the first attempts to use the scientific approach to solve problems. We are still seeking, through modern analysis, to answer the three questions posed by John Dewey in his examination of the problem solving process in 1910.'1 - What is the problem? - What are the alternatives? - Which alternative is best? As I noted earlier, Operations Research, as an organized form of research, began in Great Britain in the late 1930s with the review of individual weapons systems.

  • This study aims at analysing the process of introduction and the development of the agri-environment policy of the UK and identifying the implication for the Korean government. The UK introduced the AES policy in order to reduce the negative impact of the farming practice on biodiversity and habitats. The initial process was only possible for the enormous research results on the relationship between the farming and environment. Since the UK launched the ESA scheme in 1987, it has extended the designated areas for four stages. Based on the success of the ESA scheme, it started CSS and other schemes. However, these had a modest success and were integrated into the CSS scheme, which from then on became the main measures of the AES in the UK. The whole process of the UK case tells us that the most important work for the start of the AES in Korea would be the necessity and feasibility of the environment protection measures in Korea which could be identified from academic and scientific research on the impact of agricultural practice on the rural environment in Korea.

  • Activated sludge processes are broadly used in the biological wastewater treatment processes. The activated sludge processes are complex systems because of the many factors such as the variation of influent flowrate and ingredients, the complexity of biological reactions, and the various operation conditions. The main motivation o this research is to develop an intelligent control strategy for activated sludge process (ASP). ASP is a complex and nonlinear dynamic system owing to the characteristic of wastewater, the change in influent flowrate, weather conditions, and so on. The mathematical model of ASP also includes the uncertainty which is a ignored or unconsidered factor from process designers. The ASP model based on Matlabⓡ/Simulinkⓡ is developed in this paper. And the model performance is examined by IWA (International Water Association) and COST (European Cooperation in the filed of Scientific and Technical Research) data. The model tests derive steady-state results of 14 days. In this paper, fuzzy logic control approach is applied to handle DO concentrations. The fuzzy logic controller includes two inputs and one output to adjust air flowrate. The objective function for the optimization, in the implemented evolutionary strategy, is formed with focusing on improving the effluent quality and reducing the operating cost.

  • This article proposes a logic model for assessing the performance of the outcome of public research as a technology valuation method. It consists of two parts and eight steps. The first part is a scoring system and the second part is a validation process of the performance index derived from scoring by valuation method. The scoring in the first part generally requires a focus group method to find out the value drivers and make an evaluation table. The reason why we call it the technology valuation method is that the first part is derived from the simple evaluation of technology value using checklists for value drive. The second part is the regular technology valuation process. The model is designed for the measurement of unquantifiable outcome. Is knowledge or scientific outcome comparable to the measured outcome? If possible, how big is the unquantifiable outcome? This model is based on financial valuation techniques with clear or acceptable market data. Therefore, it cannot work solely for unquantifiable outcomes without comparable measurable outcomes, unlike economic valuation.

  • Power system restoration following a massive or complete blackout starts with energizing the primary restorative transmission system. During this primary restoration process, unexpected overvoltage may happen due to nonlinear interaction between the unloaded transformer and the transmission system. In the case of the Myanmar electric power system, there are so many wide outage experiences, including complete blackout cases, caused by 230kV line faults and so on. Consequently, Myanmar's system operators have been well trained to deal with wide blackouts. Howver, system blackout restoration has been conducted by relying on the experience of only a few specialists. So, more scientific analysis is required to meet the requirements necessary to ensure fast and reliable system restoration. This paper presents analytical results on the primary restorative transmission system of Myanmar, focusing on the problems during the early restoration process. Methodologies are presented that handle load pick-up, terminal voltage and the reactive capability limitation of black-start generators to compensate the Ferranti effect. Static and dynamic simulation with the PSSolution and EMTDC programs respectively for the six cases are performed in order to select the primary restorative transmission lines.
