클라우드 서비스가 발전됨에 따라 자원공유를 위한 가상머신의 활용도 점차 증진되고 있다. 그러나 이러한 가상머신의 활용으로 인하여 가상 영역에 따른 보안위협이 이슈가 되고 있다. 따라서 본 논문은 가상 영역에 따른 보안위협으로부터 보다 안전하고 유동적인 대처를 하기 위한 시스템을 제안하였다. 해당 시스템은 물리관제센터와 가상관제센터의 연동을 통하여 상호간의 현황을 알 수 있음으로써 가상머신 모니터링, 플랫폼 간 공격연관성 분석 등이 용이하며 자원고갈공격이나 DDoS 공격과 같은 위협으로부터 안전하다. 제안하는 시스템은 향후 클라우드 서비스 운용시 물리영역과 가상영역을 총괄적으로 관리하는 통합관제센터 활용에 적합할 것으로 보인다.

This study was conducted to examine the influence of different styles of attribution to fine dust on preventive behaviors. In addition, the mediating effect of risk perception on the relationship between attribution styles and preventive behaviors was examined. Survey data was collected from 930 Korean people from a variety of ages and regions, and a hierarchical multiple regression analysis was used to test the hypothesis. The results indicated that both external and internal attribution to fine dust had a significant positive effect on preventive behavior. The multiple regression analysis revealed that both knowledge and dread had a significantly positive effect on preventive behaviors. In addition, risk perception (knowledge and dread) partially mediated the relationship between the external attribution to fine dust and preventive behavior. However, internal attribution showed only a direct effect on protection behaviors. The significance and limitations of the study were also discussed.

This study compares the safety of nail products by reviewing domestic and foreign literature for preparing a safety management plan for reduction of human body exposure to hazardous substances that occur in nail products. We analyzed the cases of exceeding the limit value of hazardous substances. In domestic artificial nail adhesive and nail tip, toluene content was 40.3 times higher than the standard value, chloroform was 22.8 times, and antimony was 15.4 times. In developed countries, it is obligatory to provide material safety data and workplace ventilation equipment through various policy researches. However, there is no safety standard in Korea. Therefore, if the regulations for safety management should be established with each characteristic of nail product, work environment, workers, and consumers, and the awareness of hazardous substance cosmetics should be improved through development and dissemination of various educational programs, it can contribute to disease prevention and health promotion.

This study was done to identify the effects of the inter-professional education program on the knowledge, attitude, and self-confidence of patient safety in the clinical practice of nursing, physical therapy and biomedical laboratory students. Each week for 6 weeks, a lecture and group discussion were given to twenty-nine students. Data were collected by self-administered questionnaire and interview. The knowledge and self-confidence were increased but the attitude was not changed. Students showed the increased their awareness of patient safety and the importance of collaboration with other occupational groups. It is necessary to establish a inter-professional education program between departments to enhance the ability to work collaboratively based on good communication along with knowledge, attitude in clinical settings.

The purpose of this study was to explore and describe the relationship of the perception of patient safety culture, knowledge of standard precaution and performance of standard precaution among long-term care hospital nurses. Participants were 134 nurse in long-term hospital. Data were collected with structured questionnaires from January 2 to June 4, 2018. Data were analyzed by SPSS/WIN 21.0 program for descriptive statistics t-test, ANOVA, Scheffe's test and Pearson's correlation coefficient. The perception of patient safety culture were significantly correlated with knowledge of standard precaution(r=.192, p=.027), performance of standard precaution(r=211, p=.014). Therefore, in order to enhance the perception of patient safety culture and performance of standard precaution of long-term care hospital nurses, it would be necessary to enable health-care associated infections by themselves by cultivating standard precaution knowledge through systemic education and by enabling the establishment of affirmative patient safety culture.

This study examined the correlation between safety practices and safety knowledge, safety awareness and safety efficacy, and the factors influencing the safety practices of in-home child-care providers. The participants were 199 in-home child-care providers who worked at two cities in G province. Using a structured-questionnaire, the data were collected from December 2019 to January 2020. The data were analyzed using the IMB/SPSS 25.0 program. The collected data were analyzed using descriptive statistics (frequency, percent, mean, and SD), a t-test, ANOVA, Scheff test, Pearson Correlation Coefficient, and multiple regression. The mean score for safety knowledge, safety awareness, safety efficacy, and safety practices were 0.64 (SD, 0.09), 1.92 (SD, 0.37), 4.18 (SD, 0.51), and 2.55 (SD, 0.36), respectively. Safety practices were positively correlated with the safety knowledge (r=.14, p=.042), safety efficacy (r=.43, p<.001), and sub-factors of safety efficacy, self-regulation (r=.32, p<.001), enlisting social support (r=.40, p<.001), and controlling the environment (r=.39, p<.001). Enlisting social support and controlling the environment, sub-factors of safety efficacy were influenced safety practices significantly and explained 20.0% of the variance. Based on these findings, it will be necessary to develop a program that can enhance their safety efficacy for safety practices of in-home child-care providers.

Objectives: More than 80% of unintentional injury was related to risk-taking behaviors involved in child accidents. Therefore, diverse care and concerns on safety should be provided from teachers as well as parents to build child safety behaviors. The purpose of this study was to identify the effects of safety concerns from students, teachers, and parents on elementary students' safety behaviors in Korea. Methods: The 5th and 6th grade students participated in this study in 14 elementary schools in Korea and the total number of students was 1,033. The study schools were selected by the stratified cluster sampling method throughout 7 metropolitan areas in Korea. Data were collected by the self-administered survey and the questionnaires were delivered to the vice-principals of the designated schools by ground postal service and the vice-principals conducted survey data collection. The questions on students' safety concerns, teachers' safety concerns, parents' safety concerns, safety practices, safety education, and demographics were included in the survey. All survey responses were encoded into SPSS program and t-test, ANOVA, and multiple regression analysis were utilized. Results: The students taking accidents one time more per year were more than 60% and the two thirds of them recognized that their accidents were due to their risk behaviors. Parents' education on safety practices was more frequent than teachers' education; furthermore, teachers' concerns on safety behaviors were poorer than students' or parents' concerns. In terms of safety behaviors, the scores of fire and home-related safety behavior were high but the scores of traffic and bicycle, in particular, helmet wearing practice were low. Three concerns from students, parents, and teachers all were significantly related to children's safety behaviors. Conclusions: In conclusion, safety concerns from the close networks are the important indicator of child safety behaviors and, the safety training programs, therefore, for parents and teachers as well as for students need to be developed for improving children's safe behaviors.
