Being an element of plastic arts and a language of plastic forms, the color white has significant potential for improving the quality of physical environment. Colors are dealt with scientifically in chromatics, and also often become an interesting topic when analyzing a society and its history and culture. Thus, an in-depth study of the symbolism of color white and, of white pigment are required because the color has not only an important chromatic value and this should be understood a great deal, but also been the important symbol of a culture in a particular period. This paper examined the significance of the color white identified in Asian and Western cultures based on scientific and psychological understanding of the color. This also analyzed a few major white pigments, then demonstrated different methods of using the pigments and various techniques of expression used by Asian and Western painters. In addition, the paper attempted to raise awareness of the color white as chromatic color over non-color by examining the contrasting viewpoints on the color, and the changes in the viewpoints over time and place.

Introduction : The purpose of this article was to introduce the theory of flow experience to occupational therapy for various therapeutic interventions to improve the subject's physical function, activity, and participation. Review : To understand the flow experience in occupational therapy, this study summarized the concept and characteristics of the flow experience, the stages and the scientific characteristics of the brain, measurement methods, and related studies through a review of domestic and foreign literature. In occupational therapy, the subject's flow experience can be defined as 'a psychological state in which the subject is completely flow in the therapeutic activity he is doing while forgetting the passage of time'. Subjects perceived a clear goal for the task and experienced engagement when the challenge was balanced with a high level of skill. In a previous study, positive changes in attention and concentration, executive function, upper extremity function, and performance of daily living activities were confirmed in subjects who encountered the flow experience. Conclusion : If the subject's flow experience in various therapeutic interventions in domestic occupational therapy is considered, the treatment effects will be further promoted.

Backed by the fourth industrial revolution as the background of the research, VR, AR and MR have increased interest and wireless Oculus Quest is releasing, creating hardware recall and continuing virtual reality devices, and game software develop or service VR games using such devices. As a result, it is expected that VR game markets will continue to grow in the future. For this purpose, we understand the technical factors of presence and immersion that appear in virtual reality games and should be able to apply them when we produce VR games. Through the process, we analyzed elements of VR game concept, immersion, and presence and analyzed three games that were commercialized. As a suggestion, we need to take into account presence and immersion characteristics when developing and experiencing virtual reality games in the future.

The purpose of this study was development of a synthetic scale to measure young adults' views of life and death. Participants were 610 university students. The authors developed a View of Life and Death Scale including several subscales of afterlife views(belief in afterlife and retribution, belief in souls' effects and transmigration), meanings of death(liberation, nature, integration, collapse, impact, futility), death anxiety, death concern(death acceptance, death awareness) and life respect will(suicide inhibition, abortion inhibition, organ donation intention). The present study contributed to enhance our understanding of view of life and death in young adulthood. This study, therefore, could work as a stepping stone to investigate the structural relationship among elements included in views of life and death in young adulthood and to explore the consequences and determinants of personal view of life and death.

The purposes of this study were to evaluate the level of PCK which middle school science teachers have on the concept of density and to analyze the characteristics of science teachers' content representation on the concept of density by their PCK level. For that purpose, 20 science teachers were selected and asked to answer the questionnaire on the eight aspects of CoRe. Results of this study indicated that the science teachers' PCK levels were low in general and evaluated as below average. The differences among the characteristics of science teachers' content representation by their PCK level were high in seven aspects of CoRe but the one aspect of the understanding of learner's preconception. These differences were analyzed and the patterns shown by the science teachers in eight aspects of CoRe were drawn in this study. It was also found that the characteristics drawn in eight aspects of content representation shown by the teachers whose PCK level was medium were close to those whose PCK level was low rather than high in most aspects of CoRe.

The purpose of this study was to analyze elementary school teachers' understanding, certainty, and familiarity with 13 key concepts of wave physics that are presented in textbook and teacher's guidebook. 123 elementary school teachers answered concept tests and questionnaires. In the results to these tests and questionnaires, teachers demonstrated a high level of understanding and high certainty in understanding with regard to the concepts of sound generation, effect of medium on wave, timbre, wavelength, and trough and crest of wave. For the topics of sound velocity, wave reflection and wave transmission, teachers demonstrated a high level of understanding but low certainty in understanding. With regard to sound propagation, teachers demonstrated a low level of understanding and an improperly high certainty in that low understanding. Teachers lacked knowledge, i.e., displayed a low level of understanding and low certainty in sound strength, sound frequency, constructive interference and destructive interference. In constructive and destructive interference, the teachers also displayed a low level of familiarity. We analyzed the differences in teacher's understanding, certainty, and familiarity according to teacher demographics defined by the teacher's gender, teaching experience with concepts of sound, career, curriculum track while in high school, and major in university. There were no significant differences in understanding, certainty, or familiarity as defined by gender, teaching experience, and career. However, these displays of knowledge were affected by the teacher's curriculum track in high school and their major. These results suggest that the teacher's understanding of, familiarity with, and certainty in wave physics concepts are more influenced by their learning experience than by their teaching experience. Therefore, we suggest additional learning opportunities for teachers (such as teacher training programs) in order to improve teacher knowledge and correct teacher misconceptions in wave physics.

Japan enacted the "Designated Radioactive Waste Final Disposal Act" for the geological disposal of high-level radioactive waste in 2000 and began the site selection process. However, no local government wanted to participate in the siting process. Therefore, in 2015, the Japanese government developed a new site selection process during the literature survey step, and on June 28, 2017 they published a "Nationwide Map of Scientific Features for Geological Disposal" created with the aim of promoting public participation from local governments. This map illustrated the requirements and criteria to be considered in the early or conceptual stages of securing a geological repository and was useful for improving public understanding and exchanging opinions with local governments by analyzing the suitability of different geological disposal sites.

This study was to analyse the understanding of the concepts of science based on the 6th graders' levels of logical thinking in elementary schools. To achieve the goal of this study, logical thinking test was given to 108 6th graders of elementary school and 32 students were interviewed. The result of this study was as follows. First, 61.1% of students were in concrete operational period in their logical thinking, 27.8% were in their transitional period, and 11.1% were in their formal operational period. By using Flow-Map, 32 students were analyzed and their levels of logical thinking was significantly associated with their understanding of concept. Students' flexibility of cognitive structure was significantly associated with logical thinking and the levels of understanding concepts as well. However, misconception didn't show significant association with levels of logical thinking. Second, the characters of understanding of scientific concept by their levels of logical thinking was that as you get higher levels of logical thinking, their cognitive structure to understand concept was more systemized, in order and more logical. The result of this study suggested the followings in science experiment class. First, 6th graders of elementary schools had various levels of logical thinking and that affected to their understanding of scientific concepts. Therefore, lesson planning and class should be done by reflecting their different levels of logical thinking. Second, since they had different levels of logical thinking, various teaching methods should be utilized to make students understand scientific concepts more systematically.
