  • This purpose of this study was to analysis the relation of awareness and practices of oral health promotion. The subjects in this study were 133 workers who worked in Seoul, Gyeonggi province, and were at the age of 20 and up. The survey was conducted from January 16 to March 31, 2012. The collected data is statistically analyzed by SPSS. For the level oral health awareness of industrial workers, the awareness of prevention of tooth decay and periodontal disease was high, but that of necessity of oral hygiene supplies other than tooth brushing was low. For the level of oral health care practice, they showed the highest awareness for the importance of cleaning a tongue when brushing teeth, and the lowest for the importance of dental care. For oral health awareness according to the general properties, workers with average income of 2~3 million one showed higher oral health awareness than others. For oral health care practice, those who brush their teeth more than 3 times a day and who have visited the dentist during the last year had higher oral health care practice than others. For oral health awareness according to the level of interest in oral health and the status of oral health of the industrial workers, those who have higher interest in oral health turned out to have higher oral health awareness. The relation between oral health awareness and oral health care practice of the industrial workers showed a positive correlation, which indicates that the higher oral health awareness is, the higher oral health care practice is.

  • With increasing interest on scientists and the influence of science technology, their role in the modem society has been expanding. Scientists work in the laboratory as researchers, work in their expertise area as professionals, and work socially as social agents. Scientists are responsible to keep up the regulations during the research, and also are responsible for the results of the research. Therefore, there is a need of contemplation in terms of what their identity is and what their responsibilities are. Despite of this need, there hasn't been much discussion or education on the scientists social role or responsibilities as of now. This study purported to contemplate on the scientists role and responsibility, its qualification, and what it means to be a scientist as a social agent. Also the study further explored the efficient educational strategies and methods relevant to the contemplated issues.

  • In this study, we investigated scientists' perception of imagination and explored characteristics of scientific imagination. For this, we found out conceptions and characteristics based on literatures which related to imagination. We recruited eight distinguished Korean scientists who have rich research experiences by using Snowball sampling for in-depth interviews (60-90 minutes). All interviews were audio-recorded and transcribed. From the analysis of interview data, we identified their perceptions of imagination and the nature of scientific imagination which scientists reflect on during their research work. Semi-structured interview protocol was focused on: 1) how scientists perceive 'imagination' and 2) how scientists perceive the role of imagination in their scientific research. As results, we found out that scientists agreed that imagination plays an important role in scientific research process and they perceived imagination as an intrinsic part of human life. The study also indicated that participants have modern viewpoint about imagination. Moreover, we uncovered three characteristics of imagination in the research process. 1) Curiosity and interest have been a driving force for scientists' imagination. 2) When scientists use the imagination, they can be more creative during their research. 3) Imagination contemplated realistic possibilities based on the scientific knowledge, and produced the new ones. Educational implications for utilization of scientific imagination were also suggested.

  • The purpose of this study was to examine preservice secondary science teachers' understanding of the nature of science, by using nature of science (NOS) questionnaire on the basis of atomic model, and compare this to pre-studies. 'Understanding of nature of scientific model,' 'Tentativeness of scientific knowledge,' 'Subjectivity in science,' 'Use of inference and imagination,' 'Myths of the scientific method,' and 'Comparison between science and art.' were examined. Preservice teachers showed great comprehension of the tentativeness of scientific knowledge (the orbital model) and the subjectivity in science (the different interpretation about the experiment of particle scattering), but displayed the lowest comprehension of the scientific method. For understanding of nature of scientific model (the atomic model) and the comparison between science (Bohr's atomic model) and art (Picasso's work), preservice teachers brought out a combination of ontological and constructivist perspective and showed the contradictory thought about imagination in science research. In the result of comparison to pre-studies using the NOS instruments contains general terms, represented high levels of agreement about the tentativeness of scientific knowledge by using concrete examples of 'atomic model'. When concrete scientists such as Thomson, Rutherford, Bohr were presented, respondents revealed more informed views about the scientists' research method.

  • The purposes of this study are to develop a measuring instrument for perception of science classes based on the view of 'Community of Inquiry in Science Classroom' and to investigate elementary school students' perceptions with the instrument developed in the study. A total of 417 6th grade students participated in this study. As a result, first, we developed two set of questionnaire: (a) the questionnaire for the 'process of inquiry' consisted of six factors: 'problem recognition I: recognition of inconsistency,' 'problem recognition II: interests,' 'problem explanation I: hypothesis generation and examination,' 'problem explanation II: cooperative review,' 'problem solving I: reflection on the change of relationship with objects/conceptions,' and 'problem solving II: reflection on the change of relationship with community/ inquirer,' comprising a total of 42 items; (b) the questionnaire for the 'basis of inquiry' consisted of three factors:'will of conducting inquiry,' 'attitudes of conducting inquiry,' and 'structure of communication,' comprising a total of 17 items. Second, we found that elementary school students had positive recognition generally on their science classes in terms of the 'community of inquiry in science classroom,' but they had relatively negative recognition on the factors of problem recognition based on recognition of inconsistency, problem solving accompanied with reflection on the change of relationship with objects/conceptions, and attitudes of conducting inquiry based on severity and fallibilism, Finally, several suggestions for the science education were given.

  • This study examines the changes in attractiveness and social perception of mask wearers during the COVID-19 pandemic. Before COVID-19, masks were seen as a sign of infection, decreasing the wearer's attractiveness. However, with the widespread normalization of mask-wearing during the pandemic, the perception mechanisms have become more complex. The attractiveness and social perception of mask wearers now vary based on factors such as the wearer's baseline attractiveness, race, and attitudes toward masks. Consequently, research findings on perception changes due to mask-wearing have been inconsistent. This inconsistency is due to the lack of standardized experimental methods and the failure to account for individual differences among participants, as well as insufficient theoretical background in the studies. From a psychiatric perspective, it is essential to formulate and test new hypotheses centered around the psychological mechanisms related to the human behavioral immune system when studying attractiveness perception during a pandemic. Notably, attention should be given to how differences in the activation of individuals' behavioral immune systems influence perceptions of mask wearers. Understanding these dynamics can provide crucial insights into how social perceptions and aversions impact mental health, thereby shedding light on various psychiatric issues that arise during infectious disease outbreaks.

  • This study explored the ESL college learners' perceptions on integrating reading and writing in the context of the reading-to-write composition classroom. Using the panel survey (N=60) that repeatedly measured the same set of individuals at three different times during a semester, this study examined whether students' perceptions on reading-writing integrations were reshaped over the course of classroom practices. The survey instrument was developed to assess the perception scores from less integrative continua to more integrative continua on a 5-point Likert scale. A two-factor ANOVA with repeated measures was performed to evaluate mean differences across the perception groups and over the three treatment times. The results do not demonstrate a significant treatment effect, suggesting that L2 learners' integrative perceptions were stable over the course of the semester. The dynamics in the perception changes differed widely across the perception groups. This result provides insights into understanding students' reading-writing practices and thus into instructional practices applicable to the classrooms. The present study argues for 12 learners' perceptions on integrating reading and writing as a key construct to understand their literacy practices involved in the composing process.

  • The main purpose of this study is to investigate the Korean youths' impressions of the scientist. The concept of impression is assumed to reflect our significant view of an object better than that of image. That is, the basic assumption is that we tend to behave toward an object, based on its impression which is conceived to be "significant". In late August and early September 2002, a national survey for 1,204 youth (406 for 5th grad; 381 for 8th grade; and 417 for 11th grade) was conducted to find the Korean youths' impressions of the scientist. Our major finding is that the Korean youths' most impressions of the scientist were re his or her activities such as inventing, experimenting, researching, etc. And the major sources of those impressions were found to be television, book, and class. Other findings were about youths' impressions of the science teacher and opinions of the scientist as a profession. Finally, some policy-related implications based on survey results were presented at the end.
