The purpose of this study is to identify various issues contributing to the current issues of students not wanting to major in science and engineering. and further explore various strategies to encourage their higher education in the science and engineering area. The study administered survey on students' perception towards the science related profession including respondents' gender, grade, their attitude towards woman scientists, perception on the woman scientists, scientists as profession, their level of knowledge on the scientists, and if there is any they respect. The results indicated that overall perceptions on the scientists as career for high school students was positive, but there was more negative acceptance for the juniors since they are more concerned with their majors at the university: higher for students who are in the natural science area than the ones in the social science school since they are more directly related than others. The perception on the woman scientists and girls in the science and engineering majors was positive. However, there were some differences in the response level among the items. Among these, considering the job availability and conditions, the perception was more negative than the others. Also the result indicated that both boys and girls disagree that the science-related profession may be gender-inappropriate for girls due to physical and cognitive characteristics. Results also indicated the level of awareness among scientists, they had higher awareness for male scientists than that of the female, and also international ones than the national ones. And many girls did not have positive image of a successful woman scientists.

The purpose of this study is to investigate the characteristics of convergence gifted students through the their perception of the differences about scientists between Science class and Convergence class in gifted science education center. Consequently, this article reports that there are differences in the perception about scientists was distinction between applicants of Convergence and Science class. Science class applicants mainly recognized scientists as pure scientists, but Convergence class applicants recognized scientist were including mathematician, artist, architect, etc. Also Convergence class applicants thought that affective domain including 'effort', 'patience', 'interest' was more important that Science class applicants. On the other hand, when they described the scientists, Science class applicants knew their achievements as scientists more specifically than Convergence class. And to conclude, the characteristics were different between Convergence and Science class applicants in gifted science education center. Based on the result of this study, this paper suggests the following: Firstly, conceptual study is urgent about convergence gifted students in their definition and characteristics. Secondly, information regarding the criteria to select student for convergence class in gifted science education center. Finally, when teaching convergence gifted students, attention should be paid to their characteristics such affective domain.

The purpose of this study is to investigate the perception of invited foreign scientists about the actual conditions and status of operating World Class University(WCU) project in Korea. Most of them participated in the project are to promote joint research and exchange innovative ideas internationally as well as to develop their own research. Overall, they seemed to be content with the current status and operation of WCU project. They estimated the level of research universities that they are involved in positively, and also keep a positive view of their future. However, they seemed to experience some difficulties in the operation WCU project, stemming from rigid government regulations and quantity-driven evaluation mechanism. For the future, foreign scientists pointed encouraging students' research self-efficacy and research capability through frequent and direct training and interaction between faculty and students is one of the foremost tasks for the Korean research universities to become World Class Universities.

The purpose of this study was to investigate the perception of science high school students for modeling module that contain scientists' thinking process. Modeling modules about 'gas diffusion', 'ion conductivity' and 'ion mobility' were applied to science high school students. Interview, lab report, and dialogue were analyzed to comprehend features of modeling module. Students who performed modeling modules perceived that modeling modules were appropriate to experience scientists' research process. Modeling modules were kind of activity to raise 'muscle of thinking', to be needed 'new views' and 'various representations', and to contain 'designing laboratory process'. Therefore, the development of various modeling modules is needed in the near future.

This study explores the possibility and development plan for science career education in the lower grades of elementary school. Accordingly, science career education programs were developed and applied. We investigated changes in perception and interest in science before and after the programs, and analyzed surveys, research journals, student worksheets, and interview records. Science career education programs for lower-grade elementary school students have a positive effect on the perception of scientists and science. Moreover, they influence students' interest in science. Lastly, students' perception of this program was positive and gave high marks to all parameters such as interest, participation, and understanding of the program.

Human beings can perceive various aspects of sound including loudness, pitch, length, and timber. Recently many studies were conducted to clarify complex auditory scales of the human ear. This study critically reviews some of these scales (decibel, sone, phon for loudness perception; mel and bark for pitch) and proposes to apply the scales to normalize acoustic correlates of human speech. One of the most important aspects of human auditory perception is the nonlinearity which should be incorporated into the linear speech analysis and synthesis system. Further studies using more sophisticated equipment are desirable to refine these scales, through the analysis of human auditory perception of complex tones or speech. This will lead scientists to develop better speech recognition and synthesis devices.

The MPI CyberMotion Simulator provides a unique motion platform, as it features an anthropomorphic robot with a large workspace, combined with an actuated cabin and a linear track for lateral movement. This paper introduces the simulator as a tool for studying human perception, and compares its characteristics to conventional Stewart platforms. Furthermore, an experimental evaluation is presented in which multimodal human control behavior is studied by identifying the visual and vestibular responses of participants in a roll-lateral helicopter hover task. The results show that the simulator motion allows participants to increase tracking performance by changing their control strategy, shifting from reliance on visual error perception to reliance on simulator motion cues. The MPI CyberMotion Simulator has proven to be a state-of-the-art motion simulator for psychophysical research to study humans with various experimental paradigms, ranging from passive perception experiments to active control tasks, such as driving a car or flying a helicopter.

One of main purposes to educate gifted/talented science students is to express their giftedness. Most of all, it is necessary to examine thoughts of gifted/talented students including a challenge and preparation of it, because their perception of science and scientists can affect on way of thinking, study course or occupation. To investigate this, we studied on the perception of science gifted/talented students toward Nobel science prize. They have lower possibility of Korean scientists' winning Nobel science prize, but they think when they grow up adult they can win it. And most of them have a challenge of winning Nobel prize. It is necessary to study educational stimuli and strategies for gifted/talented students to prosper a challenge of science.

The purpose of this study was to gain a suggestion how to educate pre-service elementary teachers in science education. One hundred and twenty three students were involved in the questionnaire to investigate the perception of science. Many of pre-service elementary teachers had a negative image of science. They consider science to be stiff, inflexible and dull. They suggested much more of foreign scientists than Korean ones as respectable scientists. They are very interested in science related to society, and themselves. It is necessary for elementary pre-service teachers to be educated to positively improve the images of science and scientist, and to understand modern scientific philosophical perspectives. And, Korean scientific history education should be educated formally or informally for them to count on about Korean scientists as respectable ones in science education.
