  • Data mining and knowledge discovery techniques have shown to be effective in finding hidden underlying rules inside large database in an automated fashion. On the other hand, analyzing, assessing, and applying students' survey data are very important in science and engineering education because of various reasons such as quality improvement, engineering design process, innovative education, etc. Among those surveys, analyzing the students' views on science-technology-society can be helpful to engineering education. Because, although most researches on the philosophy of science have shown that science is one of the most difficult concepts to define precisely, it is still important to have an eye on science, pseudo-science, and scientific misconducts. In this paper, we report the experimental results of applying decision tree induction algorithms for analyzing the questionnaire results of high school students' views on science-technology-society (HS-VOSTS). Empirical results on various settings of decision tree induction on HS-VOSTS results from one South Korean university students indicate that decision tree induction algorithms can be successfully and effectively applied to automated knowledge discovery from students' survey data.

  • Objectives: This study aimed to design a CRA questionnaire specifically for Korean children and adolescents based on the results of two Delphi survey completed by dental professionals. Methods: Based on the CAMBRA® CRA tool, updated in 2019, we constructed a questionnaire on the oral environment and behavior of children and adolescents. Then, the CVR and I-CVI were evaluated using the results of the first and second Delphi surveys involving 20 professionals. Results: After the first Delphi survey, six items were considered invalid because their CVR and I-CVI were below the recommended values of 0.42 and 0.78, respectively. After receiving feedback from the professional panels, nine items were removed. In the second Delphi survey, the questionnaire contained a total of 21 items, all of which showed good CVR and I-CVI. After modifications based on the opinions of professional panels, the questionnaire was finalized to have 21 questions. Conclusions: The finalized questionnaire with 21 items, based on the opinions of professional panels, showed excellent CVR and I-CVI for all the items. Structured programs with updated guidelines must be developed for Korean children and adolescents in further studies.

  • The study is aimed to investigate the current status of ESD(Education for Sustainable Development) programs in private sector(businesses) carried out in Korea since UN DESD was launched in 2005, For this purpose we conducted a questionnaire survey and case studies on those companies who have supposedly pursued sustainability management Results of questionnaire surveys showed that those in charge of writing sustainability reports in companies had an extremely high understanding of SO, but were not well aware of ESD. These businesses started to pursue sustainable management due to global trends and decisions of CEOs, and most of them had divisions that took charge of or are responsible for sustainable management Sustainability issues that they mainly dealt with were corporate social responsibility, energy and climate change, but other issues were being covered, too. Internal stakeholders got involved in projects related to sustainability from the planning stage. Learning on sustainable management was primarily made through information delivery, and education programs were usually conducted for staff members and executives. Those who cooperated on their sustainable development projects were mostly local communities, universities, etc. They had few ESD programs that they directly developed and carried out, and few cases of ESD-related cooperation; and in those few cases, their partners were often elementary/middle/high schools and universities. Results of ESD case studies and questionnaire surveys showed that businesses dealt with various issues of sustainable development in addition to corporate social responsibility and diversified education programs were carried out inside these companies, Business themselves, therefore, need to be considered and researched in further detail as important targets of ESD as well as supporters or cooperation partners on ESD programme.

  • In this study, we consider to assess the information ability of individuals related to local information. Questionnaire surveys are frequently used for studies on the measuring of information index and such specified indexes of society development. However, if questionnaire papers measured individuals' abilities and such parts of quality, the subjective judgments of respondents cannot but be intervened. Therefore a method which will enable subjective points to be comparatively objectified is needed. In this study, when an attempt is being made to measure individuals' information capacity through questionnaire surveys as the process for calculating the standards of regional information levels. Cases have been looked at for times when, by using a scorecard, individuals' subjective survey result have been be changed to be comparatively objectified scores and such process. The logit model was used in the preparation of the scorecard. In this study, we have presented a clue which enables the comparative measurement about regional information gaps by using characteristics of regional population statistics.

  • Recently, underground spaces can be usually applied to the alternative of land use for parking. However, lack of window and natural light are among the most cited drawbacks associated with dark image of underground. If underground parking lots are designed to be positive and safe environment for people, openings for daylighting will play a significant role. The natural light and unobstructed view to outdoor are main elements to create optimal underground parking lots. This paper focuses on investigating the actual day lighting conditions and evaluating the day lighting performance of openings as potential lighting resources. For the study, the field measurements and Questionnaire surveys are conducted. And then, the day lighting performance of underground parking lots based on opening geometry and orientation are evaluated by scaled model experiments. As results, the feelings of safety and orientation of underground parking lots are improved by openings for day lighting regardless of the sizes. The required illuminances (daylight factor 0.5%) for underground parking lots can be satisfied in the skylight opening ratio of 4% or more.

  • Big data is structured and unstructured data that is so difficult to collect, store, and so on due to the huge amount of data. Many institutions, including universities, are building student convergence systems to foster talents for data science and AI convergence, but there is an absolute lack of research on what kind of education is needed and what kind of education is required for students. Therefore, in this paper, after conducting the correlation analysis based on the questionnaire on basic surveys and courses to improve the curriculum by grasping the satisfaction and demands of the participants in the "2019 Big Data Youth Talent Training Course" held at K University, Regression analysis was performed. As a result of the study, the higher the satisfaction level, the satisfaction with class or job connection, and the self-development, the more positive the evaluation of program efficiency.

  • This paper presents the preliminary study of an interactive rehabilitation support system for both dementia patients and their caregivers, the goal of which is to improve the quality of life(QOL) of the patients suffering from dementia through virtual interaction. To achieve the virtual interaction, three kinds of recognition modules for speech, facial image and pen-mouse gesture are studied. The results of both practical tests and questionnaire surveys show that the proposed system had to be further improved, especially in both speech recognition and user interface for real-world applications. The surveys also revealed that the pen-mouse gesture recognition, as one of possible interactive aids, show us a probability to support weakness of speech recognition.
