  • The 21st century is that both human and environment live together. The advancing knowledge concerning our environment instigates a change in understanding about the physical surroundings. The construction field particularly induces significant improvements that are environmental-friendly. To convene this demand, several manuals and guidelines related to the environmental issues have been enacted and amended. Especially the manuals and guidelines issued from Ministry of Environment (MOC) and Ministry of Construction and Transportation (MOCT) is requiring the addition of environmental knowledge in construction technology. Recently, environmental assessments and advanced environmental measures in various kinds of construction are persuasively been carried out. The policy of Total Maximum Daily Load is the one more reason for the revisions of the manual and guideline, which is really requiring the addition of the environmental knowledge in construction technology. Therefore, this research is focusing on revising the manuals and guidelines related to road construction and maintenance works issued from MOCT.

  • The design with construction knowledge and experience can eliminate inefficiency in the process of construction and improve productivity in all phase of construction project. To utilize constructability knowledge most effectively in design phase, the information must be made available to the design team at the proper point in time. Current methods for effective utilization of constructability knowledge have focused on the structuralization of constructability knowledge such as checklist, which lack the consideration of the proper point in time. However, constructability knowledge which is used at the inapposite point in time consequently leads to unnecessary rework. To minimize this inefficiency and improve productivity, project manager needs to consider the design process and know what constructability knowledge is required for specific design activities. This paper therefore presents a design process management using Dependency Structure Matrix (DSM) that focus on information flows between design activities and constructability knowledge. We expect that the results of this paper will support that design process management become comprehensive management related to every phase of construction project beyond design review or inspection in design phase, and be used as a basis of the integration of design and construction.

  • Though there is no agreement on the definition of analogical reasoning, there is no doubt that analogical reasoning is the means of mathematical knowledge construction. Mathematicians generally have a tendency or desire to find similarities between new and existing Ideas, and new and existing representations. They construct appropriate links to new ideas or new representations by focusing on common relational structures of mathematical situations rather than on superficial details. This focus is analogical reasoning at work in the construction of mathematical knowledge. Since analogical reasoning is the means by which mathematicians do mathematics and is close]y linked to measures of intelligence, it should be considered important in mathematics education. This study investigates how mathematicians used analogical reasoning, what role did it flay when they construct new concept or problem solving strategy.

  • As high density of cities, construction project is getting to be high rise, large sized and multi purposed, whereas it has some difficulties due to disordering of classification and undeveloped management systems. In this study, it would be suggested that classification method for knowledge and constraint of temporary facility in order to efficient decision making of temporary facility planning with knowledge reorganization and establishment process.

  • The construction industry has made great strides in the past decades by utilizing computer programs including CAD. However, compared to other manufacturing sectors, labor productivity is low due to the high proportion of workers' knowledge-based task in addition to simple repetitive task. Therefore, the knowledge-based task efficiency of workers should be improved by recognizing the visual information of computers. A computer needs a lot of training data, such as the ImageNet project, to recognize visual information. This study, aim at proposing building facade datasets that is efficiently constructed by quickly collecting building facade data through portal site road view and automatically labeling using deep learning as part of construction of image dataset for visual recognition construction by the computer. As a method proposed in this study, we constructed a dataset for a part of Dongseong-ro, Daegu Metropolitan City and analyzed the utility and reliability of the dataset. Through this, it was confirmed that the computer could extract the significant facade information of the portal site road view by recognizing the visual information of the building facade image. Additionally, In contribution to verifying the feasibility of building construction image datasets. this study suggests the possibility of securing quantitative and qualitative facade design knowledge by extracting the facade design knowledge from any facade all over the world.

  • Knowledge Management(KM), represented as a way to sustain or gain competitive edge in domestic construction companies since late 1990s economic fluctuation, whose priority is to transform individual tacit knowledge into explicit organizational one. Also, accompanied by academic researches, they come to turn their interests on KM leveling and its results. However, they went too far to KM results without commenting what their KM capabilities are and where they should lead. Thus, this research work suggests a leveling model for KM, especially construction company, whose role is to diagnose which parts they should be encouraged or how to strengthen their present capabilities.

  • This study aims to explore the epistemic goals that pre-service elementary teachers can construct in their biology-related knowledge construction activities, how these goals are constructed, and how the shaping of the knowledge construction activities around the goals was afforded or constrained. The research participants were 26 pre-service teachers, divided into 11 groups of two or three to engage in the activity. Their discussions and products were collected and used as data for this study. The analysis revealed that the teachers constructed three types of epistemic goals: making sense of natural phenomena, proposing the most effective course of action, and proposing solutions to problems based on their causes. Construction of different types of goals depended on the conclusions the pre-service teachers expected to draw based on the explored natural phenomena. It was found that the elicitation of the pre-service teachers' epistemic goals could facilitate their shaping of the knowledge construction activity as an evidence-based justification. The participants planned the construction of mechanistic explanations of natural phenomena with the epistemic goals of 'making sense of natural phenomena' or 'proposing solutions to problems based on their causes.' However, enacting their knowledge construction plans with sophisticated epistemic features was constrained due to the limited resources available. This study can contribute to developing instructional strategies that facilitate learners' epistemic agency and addressing epistemic agency in the development of pre-service teacher education methods.

  • Recent popularity of smart devices and social media seem to increase much interests on social learning, Despite of positive expectation on technology-based social learning, there are not many successful cases and practices of how to apply hands-on technologies and measure educational results. In this study, we tried to promote idea-sharing among learners in a classroom using web-based peer-review of assignments on a specific topic. Then we investigated effects of idea-sharing among learners in terms of individual knowledge construction. Experimental results show that idea-sharing promotes knowledge convergence and divergence, and then knowledge construction at learner's own.
