Construction projects have become increasingly complex in recent years, resulting in substantial safety hazards and frequent fall accidents. In an attempt to prevent fall accidents, various safety management systems have been developed. These systems have mainly been evaluated qualitatively and subjectively by practitioners or supervisors, and there are few tools that can be used to quantitatively evaluate the performance of safety management systems. We propose an expertise-based safety performance evaluation model (EXSPEM), which integrates a fuzzy approach-based analytic hierarchy process and a regression approach. The proposed model uses S-shaped curves to represent the degree of contribution by subjective expertise and is verified by a genetic algorithm. To illustrate its practical application, EXSPEM was applied to evaluate the safety performance of a newly developed real-time mobile detector monitoring system. It is expected that this model will be a helpful tool for systematically evaluating the application of a robust safety control and management system in a complex construction environment.

In this paper will be presented an algorithm for designing of a railway interlocking table which is a document describing the functional specification of the interlocking device. The ability to produce an interlocking table has been handed down in the signalling engineers society. And the signalling engineer makes the most of his expertise to produce an interlocking table. But, the expertise has not yet been organized into technical system, the core of the expertise is a hard nut to crack. Therefore, we analyze into signal engineering expertise, and propose a generalization of interlocking notion. Also, an algorithm is drawn up based on a train route setting principle to solve practical and general problems by computer And the performance of the algorithm is evaluated for test program based on AutoCAD technology. The evaluation result shows that it can be utilized as the effective algorithm for computer control of the signalling system as interlocking device, that it improved in safety

The purpose of this study is to derive the factors of professionalism through the literature review about professionalism to analyze the architectural field of professionalism in Korea. Factors of professionalism are defined through definition and characteristics of professionalism, historical progress of professionalism formation and development in Western nations and Korea, and various arguments and attributes by sociologists and other educational experts. Derived factors of professionalism are expertise, systemicity, exclusiveness, autonomy, and publicness. Expertise and systemicity are related with basic aspect, exclusiveness and autonomy are related with structural aspect, and publicness is related with attitude aspect of professionalism. The synchronic structure and diachronic change of architectural professionalism in Korea can be analyzed through derived five factors-expertise, systemicity, exclusiveness, autonomy, and publicness.

This study analyzed the change of teaching expertise of pre-service teachers through TPACK education. In this study, we applied a programming-based TPACK education program developed by Kim and Lee (2019) to 20 prospective teachers. To analyze the pre-service teachers' teaching expertise analyzed the lesson plan prepared before, during and after applying the educational program. As a result, Few teachers use technology in lesson plan, and the design of the instructor-led or experiment to confirmed content in curriculum or textbook. The use of technology has increased in the second Teaching Plan, but the technology was not used depending on the educational context. In the third lesson plan, all pre-service teachers were able to use technology in an educational context. Moreover, the teaching expertise of the pre-service teacher showed a statistically significant improvement in the lesson plan. This study founded that the programming-based TPACK education program was effective in enhancing the teaching expertise of the pre-service teacher.

In this study, we identified the elements of teachers'expertise for the science gifted in science high school, and examined teacher perceptions of expertise. Through previous studies and expert consultations, 5 categories such as subject knowledge, inquiry teaching, pedagogical knowledge, student guidance and school work were derived. Based on these 5 categories and sub-element, a questionnaire was constructed. Total 284 mathematics and science teachers from 19 science high schools across the country responded to the survey. The desirable level of expertise and current level of responding teachers' own expertise were examined and compared to each other, and group comparisons were accomplished according to teacher career, type of degree and final degree. Some implications are suggested for the professional development for teachers of the science gifted.

The purpose of this study is to identify the differences of student satisfaction depending on tutor's content expertise and experience in PBL of nursing. Nursing department, the subject of this study, is operating Hybrid PBL Curriculum that integrates the courses in nursing for all grades. Tutor's expertise was categorized based on their final dissertations and the clinical fields for which they worked. Tutor's experience in PBL is less than one year for beginners and more than 10 years for experts. After the PBL class for 6 weeks, the 3rd grade students were surveyed. The results showed that there was a statistically significant difference in the student satisfaction according to the content expertise, however, the student satisfaction depending on tutor's experience and the interaction effect between tutor's content expertise and experience were not significant. This study has raised the importance of the role of tutor as content expert in PBL. It is suggested that future studies be repeated for more tutors with diverse subject areas and majors to examine the differences between diverse variables other than student satisfaction.

In this article, I try to understand the changing patterns of 'politics of expertise' by looking at the change of the citizens' opinion on '4 Rivers Project', particularly the change of citizens' trust in expert, through data analysis on 'Citizen Opinion Survey on Science and Technology'. Findings are as follows: The reliability of government and the pros side experts downed, on the other hand, the reliability of the opposite side experts and environmental groups have maintained or slightly increased. This shows the fact that '4 Rivers Project' is the field of political confrontation surrounding the expertise. The government decision-making process on '4 Rivers Project' can be examined from the perspective of 'the politics of expertise', in the sense that the process is related to the utilization of scientific and technological expertise-power surrounding the project feasibility. The facts that citizens are interested in scientific-technological and ecological issues which are largely affected by expertise, and they think that the 4 Rivers Project affects the their daily lives, are the result of rising 'scientific-technological citizenship'.
