If you examine the Industrial Disaster Analysis Content that occurs every year in the small and medium enterprise, industrial disaster occurs because of manager's lack of safety and worker's unprepared safety education. Therefore effective safety education systems are needed to offer adequate knowledge and technology to the workers. On this research, to give an effective education way to decrease industrial disaster we administered to the workers who are in charge of 300 workplace in Incheon area to search actual condition of industrial disaster and to disclose a link between industrial disaster and industrial safety education. We put in effect on frequency study and examined x2 using SPSSWIN 10.0. On the research, the results shows that the industrial safety education and training are in effect regularly and the satisfaction are low. But the manager's satisfactions are high through safety education. So it shows that we need to find a way to put in effect safety education to satisfy the workers.

Purpose: The purpose of this study was to examine the effects of dual tasks on balance and postural control during standing in patients with cerebellar ataxia (CA). It was hypothesized that CA patients would exhibit different sway characteristics of the center of mass (COM) depending on the complexity of the secondary cognitive tasks compared with normal control subjects. Methods: A total of 8 patients with CA and age-matched healthy control subjects participated in this study. They were instructed to perform two balance tasks (non-dual and dual movement) with 3 different complexity of dual tasks. Range, variability, and velocity of COMs were measured. Results: According to the results CA patients showed deficits in balance and postural control with increased dual-task complexity during the static balance task in saggital sway movements. However, there was no significant difference in static balance in frontal sway. With higher difficulty in the cognitive task, CA patients took longer to stabilize their body center, while normal control subjects showed no change between conditions. In addition, CA patients had a greater COM resultant velocity during recovery in the dual-task condition compared with the single-task condition. These findings indicate that CA patients had defendable compensatory strategies in performing dual tasks. Conclusion: In conclusion, CA patients appeared to manage the priority to balance and postural control. Particularly in a situation with a postural threat such as when potential consequences of the loss of stability increase, they appeared to prioritize the control of balance and posture over the performance of the secondary task.

The number of people using the information communication have being rapidly increased owing to promote a national information policy. The rate of teenager using the information communication are over 90 percent. We can communicate quickly and easily owing to the rapid increment of the information communication. But there are adverse effects because of the rapid increment of the information communication. Specially, teenagers have been quickly influenced by the adverse effects. We must consider a counterplan for the adverse effects. Therefore, in this paper, I will survey the present status of ethics education for information communication which have been taught in school and the actual condition using information communication of teenagers. And I will analyze the connection of them. In addition, I will propose the desirable direction of ethics education for information communication.

Purpose : The research which sees width for a wide gain and loss is about brush qualitative management of the child about dental hygiene of the child is investigated the brush qualitative actual condition. Methods : The data which is collected used SPSS(Statistical Package for the Social Science) WIN 11.5 programs and analyzed, a frequency and a percentage with analytical technique, in order to grasp the general quality of the investigation object person produced to examine is about the brush quality control actual condition of the children opinion t-test (verification) frequency analyses and $x^2$(Chi-square) verifications, executed. Result : The followings are the findings of this research. First, the children about the reason which wipes this 83.4% the thing protection dental caries answer back, followed in grade and considers the difference which was visible(p<0.001). Second, wipes whether to experience is educated answer back 83.0% was educated, followed in sex and considers the difference which was visible(p<0.05). Third, when 1 time is brush quality of the children doing, in grade and the time when becomes disturbance was, most between 2~3 minutes followed considers the difference which was visible(p<0.01). Fourth, when 1 time is brush quality of the children doing, in grade and the time when becomes disturbance was, most between 2~3 minutes followed considers the difference which was visible(p<0.01). Fifth, when 1 time is brush quality of the children doing, in grade and the time when becomes disturbance was, most between 2~3 minutes followed considers the difference which was visible(p<0.05, p<.001). Sixth, Use duration of the toothbrush the child of most was 3~6 months, according to grade and sex was visible the difference which considers. Conclusion : Are oral healthily of the children is the knowledge which relates with a brush quality and practical degree important. Therefore this there must be dental health education program development will be able to improve, means must reflect the dental health education at the time of.

Many idealizations and ideal conditions in physics have been an important role in understanding of the basic physics concepts and in solving physics problems. The purpose of this study was to explore the relationships of pre-service teachers' misconception of heat with their understanding of the ideal conditions involved in solving problems of heat and temperature. Test instruments were composed of two parts. One part was asked to answer the heat conceptions, the other to write statements in relations to ideal condition hidden in the process of heat problems solving. For this study, pre-service teachers who are in four major courses in the University of Education in a local city were selected and total numbers of pre-service teachers were 108 students. The framework was developed for classifying pre-service teachers response of open items of ideal conditions of heat domains. According to the framework, each types of response were coded, analyzed and processed with a SPSS/PC program. The results are as the followings. In the heat conceptions, most of students showed correct response, and there was no significant differences between major courses. In understanding of ideal conditions, students' responses of "idealized condition relevant to problem" showed 65.2％ of them, and "not relevant idealized conditions" 15.5％, and no response 12.2%. In the 15.5% of students "not relevant idealized conditions", 10.5％ of them did not explained correctly conditions, just simply 2.7％ stated the laws in physics or formula, 1.6% generally, but irrelevantly described the idealized conditions. More importantly pre-service teachers showed very weak correlation between heat conception and understanding of ideal condition. Although we concluded there were no significant relationships of heat conception in understanding of ideal conditions in thermodynamics domain, these suggest that many other factors may influence understanding of ideal conditions in physics.

In previous private education expenses were concentrated only on expenses for elementary, middle, and high school students. Therefore, it is difficult to understand the actual condition of preschool children's private education expenses. To solve this problem, we analyze the 2013 and 2020 data of the Korea Welfare Panel to confirm the private education expenditures of pre-school children. Also, we examine the differences and changes in private education expenditures according to household variables. We selected the household variable as the socio-demographic variable of the study subject. We defined the household variable as the area and income of the household. We show the actual results of private education expenses for household variables using frequency analysis, descriptive statistical analysis, t-test, and one-way ANOVA of SPSS 27.
