The purpose of this study was to examine the effects of job characteristics and health on accident experience by analyzing the data of transportation workers according to age. The analysis used data from 'the fourth Korean Working Conditions Survey(KWCS)'. A total of 1,997 transport workers data were finally analyzed, and correlation analysis, crossover analysis and logistic regression analysis were performed. It was confirmed that there was no correlation between the age of the transport workers and the accident experience. In the relationship between the characteristics of transportation workers and the experience of the accident, it was found that, in the case of older workers, there was a significant effect in the order of 'at mistake someone else hurt', 'musculoskeletal problem', 'cardiovascular problem' and 'repetitive movements of hands or arms', the model explaining power was 56.9%(p <.01). In the case of non-older workers, it was found that 'depression and anxiety disorder', 'relationship between job and safety', 'at mistake someone else hurt' and 'labor union', the model explaining power was 21.8%(p <.01). Therefore, in order to promote prevent accidents of transportation workers in future, it is necessary to consider various variables such as health and job characteristics besides age.

The aim of this study is to confirm the effect of the experience of media education and the media literacy, the ability to understand and use media rightly. In the research results in this study, the experience of media education has a positive effect on the critical thinking disposition. Especially, the experience of media education in school influences all constituents of the critical thinking disposition positively and the experience of media education in home also does the constituents except for only truth-seeking positively. The industrial motivation, one of factors of the media literacy, has influence on all constituents of the critical thinking disposition, and the technical use ability, one of them, does the constituents except for systematicity. And inquisitiveness, objectivity, systematicity, and self-confidence of the critical thinking disposition are affected by the self-expression of the media literacy. The media audience factor has open-mindness, systematicity, and self-confidence of the disposition, and the media language factor does truth-seeking, open-mindness, and objectivity.

In computer education area, abstract thinking has played a positive role in programming ability, and language experience has also affected the ability. However, most of the studies were empirical. The practical research about the relation analysis between abstract thinking and programming ability has rarely been performed. Among various types of programming abilities such as coding, debugging, and reading, this paper focused on program understanding. We analyzed the affection relation on program understanding and the interaction effect between abstract thinking level and language familiarity. We surveyed 376 high school students on their abstract thinking levels, language familiarity, academic achievement, and the program understanding abilities of C and Scratch. From the research, we knew that the abstract thinking level played an important role in understanding the iterative program for the male students. In addition, if the students had the experience on other programming languages before entering high schools, then there was an interaction effect between abstract thinking level and program language familiarity.

The purpose of this study was to examine the actual state of injuries experience and safety accident prevention in dental hygienists. This study surveyed the actual state of injuries experience caused by apparatus and materials through a self-administered survey of 366 dental hygienists. Statistical analysis was performed using PASW Statistics 18.0. Frequency, chi-square test, t-test, one-way ANOVA were applied in this analysis. The results were as follows: Out of the 307 subjects (83.9%) experienced injuries in the last 6 months, and 294 subjects (80.3%) chose the stab as the most frequent type of injuries experience and it was followed by incised wound, scratch and burn. In relation to the differences in injuries experience depending on general characteristics, there were significant differences depending on the age, career, position, dental treatment (p<0.001) and the education (p<0.01). In relation to the differences in the level of safety accident prevention practice depending on general characteristics, there were significant differences depending on the injuries experience, age (p<0.05) and the types of dental clinics (p<0.01). Therefore, We suggest to establish a systematic process for safety accident prevention in dental clinics and emphasize the importance of prevention through continued safety education be needed.

Students have a hard time with a formal proof, which is one of most important part in mathematics education. They were taught the proof with algebraic visual materials using technology and specialized visual materials. But, they experienced the difficulty in justifying due to the lack of experimental recognition with the representation using technology. The specialized visual materials limited the extension of mathematics thinking of students because it worked only for the case that is fixed. In order to solve this type of problem, we made algebraic visual materials for 9th graders using technology and generalized visual materials so that students experience for themselves to help them to experience experimental justification, thus we recognized that they were improved in enhancing mathematical thinking.

본 연구는 가상현실을 이용하여 교통사고 후 경험하게 되는 불안감 및 공포감과 같은 심리적인 후유 장애에 대한 치료 프로그램을 개발하기 위한 예비 연구로 수행되었다. 가상현실을 통한 교통사고 후유장애 프로그램의 핵심내용이 되는 운전 주행 시나리오의 효과를 검증하고 이완훈련 등의 불안감소훈련의 효과를 피험자를 통해 검증해보았다. 총 8명 피험자(정상인 7명, 교통사고 환자1명)를 대상으로 세 가지 주행상황 시나리오를 제시하고 이후 이완훈련을 실시하였다. 그 결과 이완훈련 후 유의미한 불안감소 효과가 나타났다. 하지만 각각의 주행상황에 따라서 불안이 증가되는 경향성은 나타났으나 통계적으로 유의미한 수준에 이르지는 못하였다. 이를 종합하여 볼 때, 주로 정상인을 대상으로 한 연구임에도 불안유발경향성이 나타난 점들은 고무적이나 교통사고자를 대상으로 한 경험적인 증명이 필요하며, 가상현실을 이용한 이완훈련은 효과적인 것으로 판명되었다.

The purpose of this study is to examine epistemic thinking in middle school students in an argument-based inquiry science class. Participants of the study were 93 9th grade students from four classes of a middle school in a metropolitan city. Observations were made over one semester during which argument-based inquiry lessons on five subjects were conducted. Data was collected from argument-based inquiry activity worksheets and student questionnaires. After analysis of epistemic thinking in the written reflections, students were found to have the highest frequency of epistemic metacognitive skills, followed by epistemic cognition, epistemic metacognitive experience, and epistemic metacognitive knowledge. While investigating the effects of an argument-based inquiry science class on student epistemic thinking and after analysis of the reflections written for the first ABI activity and the fifth ABI activity, we found that all of the sub-elements of epistemic thinking have increased. The rate of growth for epistemic cognition is greatest, followed by epistemic metacognitive knowledge and epistemic metacognitive skills. Assessed for epistemic thinking, the level of epistemic thinking improved over the course of the argument-based inquiry science class. The results of the survey show that students actively participating and being recognized for their active participation in the argument-based inquiry science class are helpful in understanding scientific knowledge. Therefore, an argument-based inquiry science class is a teaching and learning program that allows students to understand and experience the epistemic nature of scientific knowledge and its construction through collaboration and agreement.

As Korea has been rapidly transformed to be a multi cultural society, it becomes essential for nursing provider to develop cultural competency. The purpose of this study was to identify impact of self-reflection, critical thinking disposition and multi cultural experience on nursing student's cultural competence. A convenience sample of 148 nursing students was obtained from a university in Gyeonggi Province. Data was analyzed using Pearson correlation and multiple regression. Significant relationships were found between self-reflection, critical thinking disposition, multi cultural experience and cultural competence in nursing student. The result of multiple regression indicates that critical thinking disposition (${\beta}=0.27$, p=.005), self-reflection (${\beta}=0.21$, p=.040) were the most consistent predictors of cultural competence and explained 26.0%. Thus, it is necessary to develop multi cultural education program including self-reflection and critical thinking disposition. The findings suggest the necessity to explore further various factors affecting the cultural competence and to conduct research for establishment a theoretical model.
