The tradition of architecture in the East and the West are different in many ways. One of the basic cause of such difference, however, is the different ways of perception of space and time. This paper aims to identify the attitude of perception of space and time in the cultures of the East and the West, and its influence on architecture. Degrees of importance placed on either space or time, as well as the modes of perception of space and time are discussed in relation to architecture. Basically, the architecture of the West seems to be more spatially oriented than the East, and this have much to do with the fact that the tradition of Western architecture is visually oriented. On the other hand, East Asian architecture have been more conscious on bodily feeling and its movement in architecture. Spatial units of traditional Eastern architecture, are arranged in such a way in which man can experience the change of space that is supposed to be organized to form a sequential message. Thus, in the East, temporal dimension is more deliberately included in the course of architectural experience compared to the cases of the West. Although it is not easy to attempt any kind of value judgment on such aspects, it is necessary to understand how the different perception of space and time influenced architectural outcome, especially when one wants to understand the cultural cause that have made the architectures of the East and the West very different. Such understanding is particularly important in East Asia where their future of architecture depends much on how they harmonize the Eastern and Western background which are already built up as two cultural structure in their consciousness to be able to create more desirable architecture for themselves.

There has been a continual need for change of teachers' assessment practices as shifting a paradigm in education. Teachers' appropriate perception of assessment influences quality of assessment and leads to change of teachers' assessment practices. This study aimed at investigate prospective elementary teachers' perceptions on assessment in mathematics. To this end, we conducted a survey with the questionnaire which was developed based on previous studies on assessment. The questionnaire was composed of 41 questions about purposes and roles of assessment, materials of assessment, reliability of assessment, methods and strategies of assessment. 95 prospective elementary teachers participated in the survey. As a result, we found that prospective elementary teachers had appropriate perception on roles of assessment, materials of assessment and strategies of assessment, whereas they showed somewhat narrow perception on reliability of assessment, purposes and methods of assessment. Based on the results, we presented possible explanations about prospective elementary teachers' lack of perception on assessment and discussed implications for prospective elementary teacher education.

Fishery products play an important role in Korean food culture, and awareness of the safety of fishery products is increasing in the seafood market. Against this backdrop, Japan has announced a plan to release radioactive water to the sea from 2023. In the case of Korea, it is adjacent to the area to be discharged, so there are concerns about securing the safety of marine products. Therefore, it is necessary to analyze the change in perception and impact of marine product consumers due to the discharge of contaminated water and to study appropriate countermeasures when discharging contaminated water from nuclear power plants. In this study, the current status of radioactive contaminated water discharge in Japan was summarized, and a survey was conducted on the change in the consumption perception of marine products according to the discharge of contaminated water to analyze the factors affecting the consumption change of domestic consumers. According to the survey, 85.3% of the respondents said that it will affect the purchase of domestic marine products if Japan starts discharging contaminated water from nuclear power plants. Moreover, 85.5% of the respondents said it will affect the purchase of imported marine products.

Rapid development of educational technology requires fundamental changes not only in the form of instruction and role of teachers in school education but also in the competency development of students. Specifically, the emergence of new technologies such as makerspace, virtual reality (VR), and robotics has made it more challenging for teachers and students in the 21st century. However, even with the argument for the changes, less has been discussed about how much in-service teachers are aware of and how they are preparing for such changes. Therefore, this study intends to explore what would be required to students and teachers, and for instructional changes with more technologies available through the lens of elementary school teachers. The study results suggest, similar to previous studies, in-service elementary teachers recognize that student competencies such as creativity, collaboration, communication, and problem-solving skills are important. They also perceived that teacher change in role and attitude, and for instructional method and classroom culture are crucial as catalysts of change. Unique and interesting finding from this study is about the importance of nurturing digital citizenship in technology-infused learning environment. The digital citizenship has been less highlighted in the past, but this study revealed it should be treated as a priority.

As the teacher-centered education is transformed into learning-centered education, the active knowledge construction of learner becomes important. Along with this change, project-based learning is receiving attention. However, there are many problems to apply the results of research to pre-service teachers because most of the previous studies have focused on elementary middle high school students. Therefore, this study examined the changes in perceptions of pre-service mathematics teachers while project-based learning progressed for one year. Pre-service mathematics teachers had less experience with project-based learning than group discussions, group activities. Also their perceptions was classified as five factors: 'Instructional effects', 'Application and participant of project-based learning', 'Achievement', 'Diffusion of project-based learning', 'Student motivation'. Pre-service mathematics teachers responded positive changes in perception that project-based learning could be motivated to students but they responded negative changes in perception that project-based learning could be distributed to school. They responded positive changes in perception that teachers can show their achievements by project-based learning but they responded negative change in perception that teachers would be fun to apply project-based learning. Also, they responded positive changes in perception that teachers and students were easy to apply or utilize project-based learning.

It is the purpose of the study to investigate how high school students understand the concept of carbon cycle according to their spatial perception ability. For this, a total of 30 male students and 33 female students, who belong to the science course of the 2nd grade at a general co-education high school located in a megalopolis of Korea and have finished the class of Earth Science I in the first semester, took part in the spatial perception ability test, and four male students and four female students were selected as members of two groups : one group of higher spatial perception ability and the other group of lower spatial perception ability, and they agreed to participate in the study and have got the test of the carbon cycle concept. The results are as followings. It was found that the students who had higher spatial perception ability recorded more scores in the carbon cycle concept, state change concept, and process concept at the factor of word association and the carbon cycle concept, state change and process concept at the factor of drawing than those who had lower spatial perception ability. Connecting link used in the systemic viewpoint was disclosed like this in the factor of causal map of those who had higher spatial perception ability : one student 2 and another one student 1 and the other two students 0 : and in the factor of drawing three students 1 and the other 0 ; But nothing was found in the factors of causal map and drawing of those who had lower spatial perception ability. In addition, it was also found that those students who had higher spatial perception ability, when compared with those students who had lower spatial perception ability, have understood the fact that carbon moves through the interaction of the earth system's lower parts; Three students, who showed higher spatial perception ability, had a low level of systemic thinking concept, and one student who had higher spatial perception ability and four students who had lower spatial perception ability did not have a systemic thinking concept.

This study aimed to identify the change in the public perception of "bats" after the outbreak of the coronavirus (COVID-19) infection. Text mining and network analysis were conducted for blog posts, the largest social network in Korea. We collected 9,241 Naver blog posts from 2019 to 2020 just before the outbreak of COVID-19 in Korea. The data were analyzed with Python and NetMiner 4.3.2, and the public's perception of bats was examined through the relationship of keywords by period. Findings indicated that the frequency of bat keywords in 2020 increased more than 25 times compared to 2019, and the centrality value increased more than three times. The perception of bats changed before and after the outbreak of the pandemic. Prior to COVID-19, bats were highly recognized as a species of wildlife while in the first half of 2020, they were strongly considered as a threat to human society in relation to infectious diseases and health. In the second half of 2020, it was confirmed that the area of interest in bats expanded as the proportion of ecological and cultural types ofresearch increased. This study seeks to contribute to the expansion and direction of future research in bats by understanding the public's interest in the potential impact of the species as disease hosts post the COVID-19 pandemic.

Phantom phenomena on the signal light was observed and change of perception-reaction tirre of the observer was rreasured. If phantcm phernrena occurs, signal light perception-reaction time by the drivers is prolonged, the extent of which rmy disturb driving. Length of the percetopn-reaction time is affected by the luminance contrast between the turned-on and turned-off signals. Based on the rreasured results, several methods to prevent phantom phenorrena were suggested.

This paper investigates whether listeners perceive a different level of politeness when the duration of the Korean sentence-final auxiliary particle '-yo' is varied. A total of 10 Korean sentences were manipulated by lengthening and shortening '-yo' by 10%, 20%, and 30%. The participants included native Korean speakers and Chinese and Japanese learners of Korean (n=10, respectively). They were asked to rate the level of politeness of the stimuli on a 9-point scale. It was found that Korean listeners perceived decreased politeness as the duration of '-yo' was shortened and increased politeness as it was lengthened. However, Chinese and Japanese listeners did not perceive a different level of politeness from the manipulated sentences. This finding suggests that it is important to teach L2 speakers that the duration of the auxiliary particle '-yo' plays a role in Korean listeners' perception of politeness.
