This study has been carried out to find out current status of understanding radiation safety expertise by workers under the present training scheme and to minimize radiation risks at work as well as to refurbish training systems for mitigation of uneasiness of the people at large in near future. Questionnaire survey asking 30 items was carried out during 3 months from May to July, 2013. The number of the overall respondents were about 500. Overall scores of hath degree of the basic knowledge and of the attitude related with radiation safety could he procured through analysis of the questionnaire data. Results were as followings: The workers of the higher academic level, the larger of the accumulated training time and the worker's personal antecedents, the more accredited license holders showed the larger scores of the basic knowledge of radiation as well as the attitude related with the radiation safety. The group having higher basic knowledge also showed the higher score in attitude related with radiation safety. The overall scores obtained from the radiation workers in industrial sector were relatively lower, in general, than those of the other sectors. These results suggest that the training program might better be separately implemented. A specific training program implementation might be desirable particularly for the workers in industrial sectors so as not only to reduce radiation risks of workers but also to mitigate the uneasiness arising among the people at large.

Protective behavior of radiological technologists against radiation exposure is important to achieve reduction of the patient doses without compromising medical achievements. This study attempts to provide a basic model for the sophisticated intervention strategy that increases the level of the protective behavior of the technologists. The model was applied to real situations in Korea to demonstrate its utility. The results of this study are summarized as follows: First, the protective environment showed the highest relationship in the factors considered, r=0.637 (p<0.01). Secondly, the important factors were protective environment in environment characteristics, expectation for the protective behavior 0.228 (p<0.001), self-efficacy 0.142 (p<0.001), and attitude for the protective behavior 0.178 (p<0.001) in personal characteristics, and daily patient -0.112 (p<0.001) and number of the participation in the education session for the protective behavior 0.074 (p<0.05). Thirdly, the final protective behavior model by a path analysis method had direct influence on the attitude 0.171 (p<0.01) and environment 0.405 (p<0.01) for the protective behavior, self efficacy 0.122 (p<0.01), expectation for the protective behavior 0.16 (p<0.01), and self-efficacy in the specialty of projects 0.154 (p<0.01). The acceptance of the model determined by the absolute fit index (GFI), 0.969, and by the incremental fit index (CFI), 0.943, showed very significant levels. Value of $x^2$/df that is a factor applied to verify the acceptance of the model was 37, which implies that the result can be accepted in the desirable range. In addition, the parsimonious fit index configured by AGFI (0.890) and TLI (0.852) was also considered as a scale that accepts the model in practical applications. In case of the establishment of some specific intervention strategies based on the protective behavior model against harmful radiation effects proposed in this study, the strategy will provide an effective way to prevent medical harmful radiation effects that could cause severe injuries to people.

The purpose of this study was to analyze the knowledge, attitudes, safety management behavior, and radiation anxiety of dental hygienists and to analyze affecting factors in order to improve the level of radiation safety management and reduce anxiety. The study period consisted of 280 dental hygienists working in Jeollabuk-do from September 10 to October 31, 2017 using the SPSS 12.0 program, frequency, descriptive statistics, and multiple regression analysis. The average knowledge level of radiation quality control was 8.07, and the correct answer rate was 75.3%. The attitude level was 96.1%, and the radiation safety management behavior was 4.11 for the photographer and 4.58 for the 'always wear a TLD (personal dosimeter) during radiography'. Patient radiation safety management behavior was 3.86, and the highest was '4.69' to confirm pregnancy of the woman before radiography. Radiation-covered lining was 3.86, and was the highest at 4.13 for 'I am concerned about fetal health when I am pregnant'. Factors affecting radiation exposure anxiety were lower radiation safety management behaviors, lower age, lower radiographic experience, higher educational background, higher monthly income, and higher job title (p<0.05). Based on the above results, dental hygienists had strong knowledge, attitudes, and safety management practices for radiation quality control. However, since anxiety related to radiation exposure was high, it is possible to improve radiation safety management level and reduce radiation exposure anxiety.

Purpose: This study was designed to identify knowledge, attitude, environment, and self-efficacy among perioperative nurses in terms of radiation protection and to describe those factors affecting radiation protection behaviors. Methods: The sample was comprised of 128 perioperative nurses who agreed to participate in this descriptive study. Data were collected from a self-administered questionnaire and were analyzed using the t-test, analysis of variance, Mann-whitney U test, Kruskal-Wallis test, Pearson's correlation, and multiple regression analyses. Results: Radiation protection behaviors were significantly different by participant's gender, length of career as a perioperative nurse, educational level and prior experience with radiation protection education. Radiation protection behaviors were significantly correlated with radiation protection environment and self-efficacy in terms of radiation protection behaviors. In the multiple linear regression models, radiation protection environment and self-efficacy on radiation protection behaviors were statistically significant predictors of radiation protection behaviors, which accounted for 50.3% of variance in dependent variable. Conclusion: This study concluded that radiation protective environment in operating room is important to promote radiation protective behaviors and radiation safety management program to enhance self-efficacy is highly recommended.

Instrumentation radar in a test range has an important role to measure target's TSPI(time, space, position, information). It is well known that it tracks a target stably using a beacon mode. But it may fail to track a target in a certain region using a beacon mode. In this paper, we modeled a simple missile shape similar to ATCMS with two beacon antenna and analyzed an antenna radiation pattern using MLFMM(Multi Level Fast Multipole Method) method. Using the analyzed result of the radiation pattern of the antenna and the attitude data of target, we simulated beacon tracking performance of an instrumentation radar. As a result of simulation, we showed that an instrumentation radar may lose the target because it tracks a area of the beacon antenna pattern.

The results of this study, suggest public communication to promote the use of radiation as follows: first, suitable information for the recipient's perception patterns should be provided, as there is a difference in risk perception and acceptance between the experts and the public. Thus, information on the necessity of nuclear power should be provided to the public, while information based on technical risks is provided by the experts. Second, since the levels of perception, knowledge, and attitudes increased highly for sectors which use radiation after the class, classes should be provided continuously to increase students' perception, knowledge, and attitude, which are all preemptive variables which induce positive behavioral changes. Third, since the seven sectors which use radiation are highly correlated, arguments for the necessity of other sectors should be based on the necessity of the medical sector.

This study conducted a survey targeting at dental hygienists working in medical institutions located in Daegu, Pusan, Ulsan Metropolitan City and Gyeongnam and Gyeongbuk Province from July 18th to August 26th 2011, in order to study factors which affect radiation safety management behaviors and improve levels of those behaviors. The results of this study are as follows. 1. There were significant differences in radiation safety management knowledge of dental hygienists, according to service institutions (p<.001), the current state of defense facilities (p<.006) and the necessity for safety management education (p<.012). 2. There were significant differences in radiation safety management attitudes, according to age (p<.014), service institutions (p<.003), work experience (p<.009), educational level (p<.002), the current state of defense facilities (p<.015), the necessity for safety management education (p<.005) and the intention to take part in the education (p<.036). 3. There were significant differences in radiation safety management behaviors, depending on experience in safety management education (p<.068), measurement of exposed dose (p<.010), the state of defense facilities (p<.001). 4. There were statistically positive correlations between radiation safety management knowledge and attitude, and between radiation safety management attitude and behavior (p<.05). 5. The regular measurement of exposed dose (p<.046) and the present state of defense facilities (p<.001) were found to be factors to affect radiation safety management behaviors. In conclusion, it is considered that building perfect defense facilities of radiology rooms and measuring the exposed does of dental hygienists on a regular basis to alert them to the danger of radiation is considerably important to improve radiation safety management behaviors.

Background & Objectives: International radiation protection committee recognized the importance of radiation protection from medical practices because the exposure to the radiation in medical practice is higher than any other exposure. The factors on knowledge, attitude and practice of radiation safety of the medical workers engaged in radiation were analyzed in order to improve radiation safety technology. Method: Questionnaires were used for 1200 radiation workers in medical institution from July 23 through September 4 and collected for analysis. Results: Different level of safety measures were practiced by age, marital status, career, and medical facility. The difference was statistically significant. Higher levels of safety measures were practiced in the age group of 50s and married persons. The workers who have more than 20 years experience have higher level of safety measures. The workers of health centers have higher level of safety measures to compare with other workers. The factors which give more concerns on safety practice were self efficacy, practice and knowledge in order. Conclusion: Safety conscious operators should get additional education program to maintain higher level of safety. The operators who do not have much safety concern should be intensive training program for self efficacy and safety.

Purpose: This study was conducted to identify factors influencing endoscopy nurses' protective behavior against radiation exposure. Methods: Data were collected using self-report questionnaires from 122 endoscopy nurses in 21 hospitals located in Seoul, Gyeonggi province and six metropolitan cities in Korea. Collected data were analyzed using SPSS 18.0 program and included multiple regression analysis. Results: 1) There were significant relationships between protective behavior and protective environment (r=.74, p<.001), number of education sessions on radiation protection (r=.32, p<.001), number of protective devices (r=.28, p=.002), number of fellow nurses (r=.27, p=.003), and protective attitude (r=.18, p=.048). 2) Protective environment (${\beta}=0.79$, p<.001), type of hospital foundation (${\beta}=0.18$, p=.011) and marital status (${\beta}=-0.13$, p=.040) significantly predicted endoscopy nurses' protective behavior against radiation exposure (adjusted R square=.58, p<.001). The most powerful predictor for protective behavior against radiation exposure was a protective environment. Conclusion: Effective protective behavior of endoscopy nurses from radiation exposure requires improvement in their protective environment. Hospital administrators and managers should make efforts to increase protective facilities in endoscopy departments and provide endoscopy nurses with regular education on radiation protection.
