  • The purpose of multiple alarm processing is to give the operator the correct information and perception of the malfunction present in the plant. In this thesis, an APS(Alarm Processing System) is studied for fossil power plants. This APS is based on a cause-consequence trees in the knowledge representation aspect for alarm and plant and adapts alarm filtering methods using fired time information in the decision aspect. Through the cause-consequence trees and filtering methods, the Alarm Processing System finds the cause alarm among the fired multiple alarms and calculates the cause degree which represents the possibility of a fault occurring in the instruments of the plant with the information of fired alarm. The knowledge base is built via interviews and questionaries with the expert operators on the Seoul power plant unit 4. Finally, the validity of the studied APS is shown via simulations.

  • Purpose: This study is undertaken from the standpoint of student-centered learning and theoretical paradigms that have developed in the business world and display conceptual affinities: the transfer of knowledge and training. Research design, data and methodology: Utilizing questionnaire surveys and multivariate data analysis are two research methodologies (CFA, SEM). Around 201 undergraduate students who were studying in Vietnam provided the data. Results: The results show importance of the faculty role in students' knowledge acquisition. The findings show that Ability to form a good relationship positively influences the development of competence. Additionally, neither ability to develop a good relationship nor learning drive or knowledge acquisition are significantly correlated with one another. The growth of competencies is positively impacted by the suitability of teaching approaches. Knowledge acquisition is favorably impacted by learning motivation, and knowledge acquisition in turn is positively impacted by competence development. Conclusions: Research has shown the important role of lecturers in students' knowledge acquisition. From this result, some implications related to lecturers are also given to help improve students' ability to acquire knowledge. Building good relationships with students (ready to answer questions, positive relationships) and good expertise will help increase learning motivation, ability to acquire knowledge as well as improve development for students.

  • The study uses agricultural knowledge system theory to explore how traditional knowledge applies to the linkage system of agricultural research and extension in rural Korea. By agricultural knowledge system we emphasize the dynamic networks of actors, processes of negotiation, and the diverse ways in which knowledge is constructed and performed. The knowledge systems reflect the idea that the boundaries between knowledge groups are not closed and that there could be considerable overlap between knowledge system. The results of this study are the following : First, we should know that some extension agents clearly value farmer knowledge and try to facilitate farmer-to-farmer communication. Extension plays a significant role in the knowledge-creation process and shaping communities because knowledge processes are embedded in social processes that involve aspects of power, authority, and legitimization. Third, the constructions of agricultural knowledge systems thus include social interactions, communication, and the diverse processes individuals employ create, use, and evaluate multiple types and sources of information through the linkage between agricultural colleges and Rural Development Administration (RDA), establishing the research institution of research and extension linkage, exchange research agent with extension agent, and bottom-up approach. Second, we should know that the focus of traditional knowledge development is rural community development as a community process. Nowadays the sessions of the Intergovernmental Committee of World Intellectual Property Organization (WIPO) cover two lines of inquiry, which are the use of existing standards of intellectual property for the protection of traditional knowledge and that of new legal standards, eventually in the from of sui generis mechanisms of protection.

  • The characteristics of a power plant changes as it operates for a long time and/or for different operating point. As a result, operators must retune gains of the controllers for better performance. In fact, skilled operators can retune the gains in reference to recorded data obtained by a test called dynamic test. The dynamic test, however, requires much time, and can be heavy burden for operators. In this paper, an expert knowledge-based auto-tuner is designed for drum-type boiler controllers of a fossil power plant using fuzzy logic. The performance of the proposed auto-tuner is shown via computer simulation and the simulation results show that the proposed auto-tuner is satisfactory for the desired performance.

  • This study explores how to reconcile science and policy in the wind energy sector by providing a conceptual framework for better understanding evidence-based policymaking (EBPM). Regarding this framework, the core issue is to discover how knowledge is formed over time, and which factors affect this knowledge formation. Comparative cases of wind industry emergence in Spain and Britain are examined. This analysis shows that knowledge formation initially starts in the scientific arena in parallel with its formation in the practical, and is followed by political knowledge formation near the beginning of commercial projects. Regarding knowledge formation, three more comparisons are made between wind industry emergence in Spain and Britain: the different approaches to R&D projects, the different adoptions of supporting measures, and the different ways of coping with public opposition. The factors affecting the comparisons are mainly perceptions of energy supply, nuclear power, environment and science and technology. Communication and unfamiliarity are likely to affect the comparisons in EBPM.
