In this study, gifted children's perceptions of scientists were investigated. The subjects were 91 elementary students who were registered in educational program for the gifted. This study was conducted using Draw-A-Scientist-Test (DAST) and questionnaires about the life of scientists. As the results, most scientists were depicted as well-featured and young people. There was a tendency that boys mainly described scientists as male, but girls as female. Many of the students perceived scientists as those who did significant works to try to help other people and pursue the novelty The general perceptions of the gifted on scientists were positive. Majority of students, however, perceived that scientists worked indoors with glassware or chemicals. Relatively, fewer students described books, other materials, and technologies including computer. Many of the students perceived scientists＇work as research or invention. Concerning working pattern, students mainly replied that scientists worked alone. In order to make students＇restricted perceptions enhance for opened and flexible manner, various educational methods need to be implemented.

Purpose - Average using time of smart-phone for Korean people is 3 hours 39 minutes and most people who are using a computer at home and their workplace can be affected over force to neck and shoulder due to unstable body posture. musculoskeletal disorders which caused by unstable body posture can affect strongly to decrease work efficiency. So this research is designed to measure the effect of using computer & smart-phone on decreased work efficiency due to musculoskeletal disorders and mediating effect between decreased work efficiency and musculoskeletal disorders. Research Design, Data, and Methodology - The author has developed a questionnaire with 6 hypothesis on the basis of previous research result with 5 constructs. The questionnaires were also made by interview and E-mail. 300 copies of questionnaires were distributed and 282 questionnaire were used for the analysis as valid data responses. SPSS ver.21.0 were used and made Cronbach's α and reliability test, correlation, Baron & Kenny 3 step mediated regression analysis. Result - Cronbach's α shows 0.770~0.954 and C.R. is 0.963~0.997 which is higher than 0.7. and AVE was 0.867~0.933. So the data are all acceptable condition. Using for a long time of a computer & smart-phone has a positive effect on musculoskeletal disorders. This means, it can cause musculoskeletal disorders if people use a computer & smart-phone for a long time due to unstable body posture. And musculoskeletal disorders can effect strongly decrease work efficiency. This study also found out that a long time of using computer can cause musculoskeletal disorders rather than using smart-phone a long time. To check mediate effect of musculoskeletal disorders between using a computer & smart-phone and Decreased Work Efficiency, author used 3-step mediated regression analysis of Baron & Kenny (1986). Using a computer for a long time mediate partially and using a smart-phone for a long time mediate completely. This means that using a smart-phone a long time is not the actual reason to decrease work efficiency. But using level of smart-phone is increasing rapidly day by day. So we need to make additional research about this matter seriously. Conclusion - Nowadays, people can not live on without a computer & smart-phone even a moment. But, using a computer for a long time will affect to cause musculoskeletal disorders and it will effect strongly to decrease work efficiency. Before, we thought over that musculoskeletal disorders were diseases of elder people. But, we found out from this study that musculoskeletal disorders can be happen to any people, even children, or workers in heavy industry or engaged in brain work. So we need to be careful when we use a computer for a long time. People also need to be careful to keep correct body posture when using both a computer and smart-phone since a smart-phone became more popular and using time level became longer. Due to increased income and living standard of people, physical growth of young people is so rapid. But the physical environment of society is not suitable for them since it can not follow up the speed of growth. Suitable work table is very important to prevent musculoskeletal disorder which can affect decrease work efficiency. For a person, a society or country, increased productivity is very important since it can directly connected to the job satisfaction. Education and reeducation for the people is also important, but to teach them how to keep good condition of health will be more important since it can increase the quality of work efficiency and quality of life. Computer and Smart-phone is one the best invention of modern society, but it can cause mental and physical disease which can affect decrease work efficiency and productivity. So it is necessary to observe attentively for the situation continually.

Objective: The purpose of this study is to investigate the effects of childcare teachers' teacher efficacy, psychological burnout and the practice of respecting rights for infants. Methods: For this study, questionnaires were distributed to 398 childcare teachers in the cities of I and S. The collected data were analyzed by descriptive statistic, multiple regression and Cronbach's ${\alpha}$ for reliability by SPSS-WIN computer program. Results: The results yielded some interesting results. First, childcare teachers were shown to have higher respecting rights for infants but just average teacher efficacy rates. Secondly, the study showed a positive correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. However, there was a negative correlation between the practice of respecting rights for infants and psychological burnout. There was also a negative correlation between the practice of respecting rights for infants and childcare teachers' teacher efficacy. Third, the higher the childcare teachers' teacher efficacy of childcare teachers, the more positive influences existed in the practice of respecting rights for infants. It also showed that the lower the degree of psychological burnout, there was a negative impact on the practice of respecting rights for infants. Conclusion/Implications: The results of this study suggest that a support plan is needed to boost childcare teachers' teacher efficacy, and to lower the psychological burnout of childcare teachers with regards to the practice of respecting rights for infants.

The present study examined the scientific awareness appearing in Korean tokusatsu series by focusing on Vectorman: Warriors of the Earth. As a work representing Korean tokusatsu series, Vectorman: Warriors of the Earth achieved the greatest success among tokusatsu series. This work was released thanks to the continued popularity of Japanese tokusatsu since the mid-1980s and the trend of robot animations. Due to the chronic problems regarding Korean children's programs-the oversupply of imported programs and repeated reruns-the need for domestically produced children's programs has continued to come to the fore. However, as the popularity of Korean animation waned beginning in the mid-1990s, inevitably the burden fr producing animation increased. As a result, Vectorman: Warriors of the Earth was produced as a tokusatsu rather than an animation, and because this was a time when an environment for using special effects technology was being fostered in broadcasting stations, computer visual effects were actively used for the series. The response to the new domestically produced tokusatsu series Vectorman: Warriors of the Earth was explosive. The Vectorman series explained the abilities of cosmic beings by using specific scientific terms such as DNA synthesis, brain cell transformation, and special psychological control device instead of ambiguous words like the scientific technology of space. Although the series is unable to describe in detail about the process and cause, the way it defines technology using concrete terms rather than science fiction shows how scientific imagination is manifesting in specific forms in Korean society. Furthermore, the equal relationship between Vectorman and the aliens shows how the science of space, explained with the scientific terms of earth, is an expression of confidence regarding the advancement of Korean scientific technology which represents earth. However, the female characters fail to gain entry into the domain of science and are portrayed as unscientific beings, revealing limitations in terms of scientific awareness.
