This research aims is to confirm the influence of a teacher's teaching style and teaching career on instructional analysis. Through this, the differences in the relevant elements' view points on a class and those in teachers' analysis view points on class criticism and instructional analysis at the education field can be investigated. For this study, the teaching styles of 198 elementary school teachers were categorized, their teaching careers were checked as teaching career and set them as covariate, and the differences in the view points on the analysis of the class climates were verified depending on each teaching style. As the research result, meaningful differences were found in four areas of the elements of class climates analysis, that is, creativity, vitality, precision, and gentleness. In the analysis of the class climates, the teachers with a professional style among the teaching styles gave the highest grades to creativity in the same class, those with a facilitating style to vitality, those with a role model style to precision, and those with a facilitating and role model style to gentleness. On the other hand, those with an authoritative and a delegating style were proved to give the lowest grades in general class climates. It means that teachers with different teaching styles have different viewpoints when analyzing a class, and those with a professional, a role model and a facilitating style have a relatively stronger intention to analyze a class through reflective introspection and permissive recognition.

The purpose of this study was to identify the effect of Genibo program robot-based learning(R-Learning) on a pre-schooler's mental state. To achieve above study purpose, the subject of this study was selected 46(teacher 2, five years old pre-schooler 44) from pre-school childrens in Kyongki Y city(R-Learning activity participants group 21: boys 10, girls 11. non-participants 25: boys 13, girls 12). R-Learning program is consist of 5 field about 20 contents using Genibo robot, were applied to the experimental group and the pre-post test was conducted using the EQ assessment tool and observations. The data were analyzed by t-test using the SPSS(ver 18.0) program. The results were as follows: First, the exposure of robots to pre-schoolers in practical situation has shown positive influence to the children's emotional well-being. Positive improvements were observed in the four sub categories of the EQ assessment after exposure. Second, the Genibo used for this study, is a biomimetic AI based robot mimicking the behavior of a pet dog. This is related more or less to the specifications of a pre-school education where animals are used as a 'friendly medium' to facilitate the learning process. Third, the robot exposure gave benefit to all the ones in the sample, regardless of sex. Furthermore, It is suggested that promising potential for robots to be utilized as a new educational media plus facilitator, R-Learning is related more or less to the specifications of a pre-school education where animals are used as a 'friendly medium' to facilitate the learning process, and when applying them for education, stereotyping the likes of sex is overrated - instead, the focus should be more on the pre-schoolers' / childrens' individual traits, learning curve differences and alike.

This study examined the oral health knowledge of childcare teachers and their awareness of the prevention effects against dental caries. The subjects in this study were 433 childcare teachers in Seoul, Gyeonggi Province, Busan and South Gyeongsang Province, on whom a survey was conducted for five months, beginning in March, 2013. Hospitals (56.6%) were the most common route by which the childcare teachers acquired oral health knowledge. Regarding the distribution of the correct answers on oral health knowledge, every teacher gave the correct answer to the item "When a tooth comes out, it should be kept in milk and then be brought to a dental clinic," and the smallest number of them (35.1%) gave the correct answer to the item "When a tooth comes out, it should be washed with water." Concerning the level of oral health knowledge, the respondents, who worked in Busan and South Gyeongsang Province (p<0.001), who worked in childcare centers with more children (p<0.001), who were younger (p<0.001), and who were junior college graduates (p=0.002) had better oral health knowledge. In regard to the awareness of the prevention effects against dental caries, the respondents who were older (p<0.001) and who were married (p=0.002) were more aware of the prevention effects. According to position and career, teachers who were assistant principals (p=0.023) and had worked for 10 years or more (p=0.009) were more aware of the effects. Therefore, child care teachers should acquire accurate knowledge to improve the oral health of children, and regular training programs for age and education are needed.
