BACKGROUND/OBJECTIVES: The current South Korean government policy on food irradiation technology should be reformed based on an in-depth investigation of the communications aspect, because the issue is no longer of a technological nature, given the proven safety and efficacy of the processes. SUBJECTS/METHODS: The target population of the education program consisted of elementary, middle, and high school students attending 310 schools in South Korea (2013: 63 schools, 2014: 104 schools, 2015: 143 schools). Data subjected to analysis were 13,327 pre-education and 12,641 post-education questionnaires received from 7,582 elementary, 2,671 middle, and 3,249 high school students who participated in the education program from May 2012 to April 2015 (n = 12,831), after the exclusion of inadequately filled-in questionnaires. RESULTS: Analysis of the three-year educational effect trend was conducted by comparing levels of variables before and after food radiation education. The analysis yielded the finding that the post-education levels were significantly higher for all variables. That is, for interest in education, perception (necessity, safety, subjective knowledge, and information acquisition), objective knowledge, and attitude, with the sole exception of objective knowledge in 2013. CONCLUSIONS: Given that post-education levels of perception, knowledge, and attitude concerning irradiated foods increased considerably compared to pre-education levels, behavior change should be induced by providing continuous education to enhance, these primary variables.

These days, human behavior (human factor), the main cause of traffic accidents, has drawn more attention. Research on driving behavior based on DBQ(Driver Behavior Questionnaire), the analysis tool of driving behavior, has been conducted actively. In domestic previous studies, their analysis subjects were limited to researchers or military officials, and their analysis methods were based on factor analysis and regression analysis. Therefore, this study tries to find the factors of general drivers' driving behavior that influence risk driving, and to analyze their influential relationship. Regarding study scope, general drivers with driving career were asked to answer DBQ questionnaire, and 300 effective samples were analyzed. In addition, previous studies were investigated to draw the three measurable attributes of DBQ-'Lapse, Mistake, and Violation'-as main factors of traffic accidents, and structural equation model was applied to design risk driving behavior model. To identify the difference between risk driving groups, this study made use of multiple group analysis. The analysis came to the following results: First, according to the examination of the hypothesis that 'Lapse, Mistake, and Violation factors will influence risk driving behavior', all factors were found to be statistically significant. Regarding their level of influence on risk driving behavior, Violation was 0.464, Lapse 0.383, and Mistake 0.158, and thus Violation was analyzed to be the most influential. Secondly, according to the examination of the hypothesis that 'the influence of Lapse, Mistake, and Violation factors on risk driving behavior will be different by risk group', the influence of Lapse on risk driving behavior was found to be different by risk group. It is expected that the study results will be used as a fundamental program to introduce traffic accident prevention program and education that takes violation and lapse into consideration.

Purpose: The purposes of this study were to provide information about safe actions during the practice of dental technology, promote belief in safe actions among the students of dental technology, and reinforce their knowledge about how to act safety. Methods: Open questions were asked to 120 sophomores majoring dental technology to understand the target group's belief about safe actions. Following the instructions by Ajzen & Fishbein, the collected data were grouped according to similar beliefs. Those beliefs of the highest frequency were given a priority and got to represent the belief level of the target group. Even with belief changes, however, they would not be able to practice safe actions if they had no knowledge about how to do safe actions. For desirable behavioral changes among the students, the students were then asked to discuss the current state of safety accidents and issues focusing on the materials and processes used in the practice and give presentations regarding the subjects to identify risk factors. Then the identified risk factors were used to devise the program contents so that the students could practice safe actions through accurate behavioral approaches and belief changes by educating them about how to act safely by the practice processes and the involved materials and devices. Results: Not only do the students of Dept. of Dental Technicians have difficulties with the complex practice processes while practicing to make dental prosthesis, but they are exposed to the risk of accidents as they're poor at dealing with the materials and devices. Although there is a definite need for accident prevention education programs before practice, the reality is that the school doesn't the schoosuch education. Based on the judgment that an education program designed to reinforce belief for behavioral changes would generate effgrams results, an education program was developed by applying the Theory of Planned Behavior(TPB). Along with their beliefs, the current state of accidents n. Basepractice, demand for safety education, and practice level of safe actions were used to device the contents of accident prevention education and to develop an accident prevention education program for dental technology. Conclusion: The study presents an accident prevention education program developed to reinforce dental technology students' beliefs and knowledge and to help them do safe actions during practice.

The U.S. government have concerned about food safety over the last two decades. The concept of the continuum, “from farm to table” was created to explore ways to prevent foodborne illnesses in all stages of food systems. On the continuum, consumers were recognized as the last line of defense to prevent foodborne illnesses, and much efforts were made to educate them safe food handling. This research was conducted to investigate infant formula handling and hand-washing behaviors of low-income families, especially parents and guardians of infants. The subject was selected from participants of the Special Supplemental Nutrition Program for Women, Infants, and Children(WIC), a federal program for low-income families in the U.S. Stratified 200 local WIC offices were randomly selected based on the number of WIC participants in each state, and 20 randomly selected WIC participants from each selected office were asked to complete questionnaires. SPSS for Windows was used for statistical analyses including frequency, cross- tabulation, and chi-square analyses. A total of 87 WIC offices returned completed question-naires (N = 1,598), and 492 were parents/guardians of infants. Most respondents were white (51.3%), high school graduates (41.5%) , and participated in WIC>1 yew. Most respondents (80.9%) teamed about food safety from WIC, and only limited number of respondents (10.2%) used the Internet for food safety information. Most respondents stored prepared formula safely (94.6%) and discarded formula left in the bottle after feeding (84.5%) , but fewer used brushes to wash formula bottles (71.3%) and boiled water(15.2%) Chi-square analyses showed respondents in different race/ethnicity had different food handling behaviors. Respondents showed generally good hand-washing behaviors as 94.2% always washing hands after using restroom, 93.2% after touching meat items, and 87.l% before preparing foods. Fewer respondents, however, washed hands after changing baby diapers (77.0%) and touching pets (67.2%). Researchers concluded that WIC education on food safety was effective, as limited food safety education covered during WIC education were followed well (e.g., storing prepared formula and discarding leftover). However, results also indicated that there were many behaviors needed to be reinforced especially to overcome family tradition and culture on food handling behaviors. The WIC may serve as good food safety resources and education agents utilizing mandatory education sessions because the vast amount of food safety information on the Internet was not readily accessible for this low-Income Population.

컴퓨팅 환경에서 각종 보안 위협들의 핵심에는 악성 실행파일들이 있다. 전통적인 시그니처 기반의 보안 시스템들은 악의적인 실행파일들 중에서 알려지지 않은 것들에 대해서는 런타임 탐지에 어려움이 있다. 그러한 이유로 런타임 탐지를 위해 시그니처가 필요 없는 정적, 동적 분석 방법들이 다각도로 연구되어 왔으며, 특히 악성 실행파일을 실제 실행한 후 그 동작상태를 모니터링 하는 행위기반 동적 분석방법들이 많은 발전을 이루어왔다. 그러나 대부분의 행위기반 분석방법들은 단순히 몇 가지 행위나 비순차적인 분석정보를 제공하기 때문에, 차후 악성여부를 최종 판단하는 방법론에 적용하기에는 그 분석정보가 충분하지 않다. 본 논문에서는 악성 실행파일이 실행되는 동안 발생할 수 있는 행위들을 분류하고, 이를 모니터링 하는 프로토타입 프로그램을 구현하였다. 또한, 악성 실행파일을 직접 실행하는 것은 제한된 컴퓨팅 환경에서 이루어지기 때문에, 실제 악성 실행파일을 모니터링 한 결과를 토대로 행위기반 모니터링 방법이 극복해야 될 이슈들에 대해서도 언급하고 있다.

There are a lot of uncertainties in the severe accident phenomena and scenarios in nuclear power plants (NPPs) and one of the major issues for severe accident management is the reduction of these uncertainties. The severe accident management aid system using Probabilistic Safety Assessments (PSA) technology is developed for the management staff in order to reduce the uncertainties. The developed system includes the graphical display for plant and equipment status, previous research results by a knowledge-base technique, and the expected plant behavior using PSA. The plant model used in this paper is oriented to identify plant response and vulnerabilities via analyzing the quantified results, and to set up a framework for an accident management program based on these analysis results. Therefore the developed system may playa central role of information source for decision-making for severe accident management, and will be used as a training tool for severe accident management.

Background: E-learning-based programs have recently been introduced to the occupational safety and health (OSH) education for migrant workers in Korea. The purpose of this study was to investigate how the factors related to migrant workers' backgrounds and the instructional design affect the migrant workers' satisfaction with e-learning-based OSH education. Methods: The data were collected from the surveys of 300 migrant workers who had participated in an OSH education program. Independent sample t test and one-way analysis of variance were conducted to examine differences in the degree of learning satisfaction using background variables. In addition, correlation analysis and multiple regression analysis were conducted to examine relationships between the instructional design variables and the degree of learning satisfaction. Results: There was no significant difference in the degree of learning satisfaction by gender, age, level of education, number of employees, or type of occupation, except for nationality. Among the instructional design variables, "learning content" (${\beta}=0.344$, p < 0.001) affected the degree of learning satisfaction most significantly, followed by "motivation to learn" (${\beta}=0.293$, p < 0.001), "interactions with learners and instructors" (${\beta}=0.149$, p < 0.01), and "previous experience related to e-learning" (${\beta}=0.095$, p < 0.05). "Learning environment" had no significant influence on the degree of learning satisfaction. Conclusion: E-learning-based OSH education for migrant workers may be an effective way to increase their safety knowledge and behavior if the accuracy, credibility, and novelty of learning content; strategies to promote learners' motivation to learn; and interactions with learners and instructors are systematically applied during the development and implementation of e-learning programs.

Because of financial and safety concerns, there are needs for more accurate prediction of bridge behavior. Underestimation of the bridge load carrying capacity can have serious economic consequences, as deficient bridges must be repaired or rehabilitated. Therefore, the knowledge of the actual bridge behavior under live load may lead to a more realistic calculation of the load carrying capacity and eventually this may allow for more bridges to remain in service with or without minor repairs. The presented research is focused on the reliability evaluation of the actual load carrying capacity of existing bridges based on the field testing. Seventeen existing bridges were tested under truck load to confirm their adequacy of reliability. The actual response of existing bridge structures under live load is measured. Reliability analysis is performed on the selected representative bridges designed in accordance with AASHTO codes for bridge component (girder). Bridges are first evaluated based on the code specified values and design resistance. However, after the field testing program, it is possible to apply the experimental results into the bridge reliability evaluation procedures. Therefore, the actual response of bridge structures, including unintentional composite action, partial fixity of supports, and contribution of nonstructural members are considered in the bridge reliability evaluation. The girder distribution factors obtained from the tests are also applied in the reliability calculation. The results indicate that the reliability indices of selected bridges can be significantly increased by reducing uncertainties without sacrificing the safety of structures, by including the result of field measurement data into calculation.
