Purpose: The purpose of this study was to identify which nursing interventions are the most effective in fall prevention for hospitalized patients. Methods: From 3,675 papers searched, 34 were selected for inclusion in the meta-analysis. Number of fallers, falls, falls per 1,000 hospital-days, and injurious falls, fall protection activity, knowledge related to falls, and self-efficacy about falls were evaluated as outcome variables. Data were analyzed using the Comprehensive Meta Analysis (CMA) 2.2 Version program and the effect sizes were shown as the Odd Ratio (OR) and Hedges's g. Results: Overall effect size of nursing interventions for fall prevention was OR=0.64 (95% CI: 0.57~0.73, p <.05) and Hedges's g= - 0.24. The effect sizes (OR) of each intervention ranged from 0.34 to 0.93, and the most effective nursing intervention was the education & environment intervention (OR=0.34, 95% CI: 0.28~0.42, p<.001), followed by education intervention (OR=0.57, 95% CI: 0.50~0.67, p=.001). Subgroup analyses showed that multifaceted interventions (OR=0.76, 95% CI: 0.73~0.79, p<.001) were more effective than unifactorial interventions, and that activities for prevention of falls (OR=0.08, 95% CI: 0.05~0.15, p<.001) showed the largest effect size among outcome variables. Conclusion: Falls in hospitalized patients can be effectively prevented using the nursing interventions identified in this study. These findings provide scientific evidence for developing and using effective nursing interventions to improve the safety of hospitalized patients.

The purpose of the study was to identify the effect of structured patients education had on prevention of osteoporosis, with fracture and the resulting of life style changes in patients. In this study, a non equivalent control group pre and a post test design was employed. Data were collected through an interview process using questionnaires from April to December of 1999. The subjects, consisting of 59 patients with fractures and over 40 years of age, were diagnosed in K University Hospital. This study tested the patients knowledge at three times. The times were before the program 2 weeks into the program, and 6 months after education program. Life style change related to prevention of osteoporosis was shown twice (before and 6 months after the education program) in the experimental group, and control group went without it. The instruments used for this study were developed by literature review according to a reliability test. Data was analyzed using X2 test and t test to determine similarities between the experimental and control groups. The hypothesis was tested using repeated measures of ANOVA, t-test and Pearson correlation coefficients. The results of the study were summarized as follows: 1. The first hypothesis was accepted: a higher level of knowledge about osteoporosis was found in experimental groups who received education than to the control group during the period (F=19.82, p=.0001). 2. The second hypothesis was accepted: a higher level of life style changes about osteoporosis on experimental group were recorded than as compared to control group (t=3.55, p=.001). 3. The third hypothesis was accepted: the higher the knowledge about osteoporosis the higher the level of performance of life style changes about prevention of osteoporosis (r=.600, p=.0001). In conclusion, structured patient education in patient with fractures improved the level of knowledge about osteoporosis and more likely undergo of life style changes 6 months after the education program. Also reeducation would be needed 6 months after program ends. That is structured patient education in pamphlet form would be very effective in nursing intervention that may to result in life style changes. Therefore further research is needed to reinforce the education material and to generalize the education effect.

Silicone tetrachloride (SiCl₄) leak accidents cause enormous human and environmental damage because it is highly toxic. Some handling facilities use water curtains to reduce the impact range of SiCl₄. Although the water curtain is known as one of the most efficient technologies for post-release mitigation, its effect on reducing SiCl₄ concentration needs to be investigated scientifically and quantitatively. In this study, three-dimensional computational fluid dynamics (CFD) was used to investigate the physical and chemical effects of water curtains as a release-mitigation system for SiCl₄. SiCl₄ is released and dispersed five seconds prior to the operation of the water curtain. Once the water curtain works, the SiCl₄ reacts chemically with the water and its concentration decreases rapidly; it reaches an emergency response planning guidelines level 2 (ERPG-2) of 5 parts per million (ppm) at about 570 m. We observed, however, that the physical effect of water curtains on reducing SiCl₄ concentration is insignificant when the chemical effect is eliminated. These results are crucial since they can be a scientific and quantitative basis for the 'technical guidelines for estimating the accident affected range'. In order to protect the public from chemical accidents, more toxic gas mitigation technologies need to be developed.

Purpose: This study aims to find empirical evidence and clarity on the phenomenon of the direct and indirect effect of perceived behavioral control on fraud prevention through whistleblowing intention. This study also aims to understand the influence of organizational ethical culture moderating between whistleblowing intention and fraud prevention. Research design, data, methodology: The samples of this research are 236 respondents consisting of the Head of the Finance Subdivision and Head of the Reporting Planning Subdivision and the finance staff who were determined using the purposive sampling method. The data obtained were analyzed using the Structural Equation Modeling technique. Results: The study results show that perceived behavioral control positively and significantly affects whistleblowing intention. In addition, perceived behavioral control does not affect fraud prevention mediated by whistleblowing intention. Furthermore, organizational ethical culture moderates whistleblowing intention and has a positive and significant effect on fraud prevention. Conclusions: This study concludes that the phenomenon of scandal that often occurs on a television is not a habit that must be followed. It requires an active role from the community as a form of concern for whistleblowing. Futher researchers can add other construct variables, such as good corporate governance to assess the performance improvement of the organizational layers, both internally and externally

Purpose: This study was to develop and test a theoretical model based on the revised health belief model explaining osteoporosis prevention behaviors among postmenopausal women under 65. Methods: This secondary data analysis included 342 postmenopausal women under 65 from original data sources of a total of 734 women. The measured instruments were scales for osteoporosis awareness, osteoporosis health belief scale (benefit, barrier, susceptibility, severity, and health motivation), self-efficacy, and osteoporosis prevention behaviors. Data were analyzed using SPSS/WIN 20.0 and AMOS 20.0. Results: The mean age of the subjects was 55.2 years and the mean age of menopause was 51.10. The hypothetical model of osteoporosis prevention behaviors was relatively fit. Osteoporosis prevention behaviors were significantly explained up to 62% by expectation factors (relative benefit, self-efficacy, health motivation) and modifying factors(knowledge only). Expectation factors of health belief had a mediation effect between modifying factors and prevention behaviors. Conclusion: This study partially supported the revised health belief model for explaining osteoporosis prevention behaviors. It provides a basis for developing an educational program focusing on expectation factors and knowledge with the aim of behavioral changes for osteoporosis prevention.

Purpose: This descriptive study investigated the mediating and moderating effects of fear of fall on the relationships between health belief on fall, fall-related knowledge and fall prevention behaviors among older adults Methods: We enrolled 229 older adults residing in a senior citizen hall and community welfare center, and investigated their health belief on fall, fall-related knowledge, fall prevention behavior, and fear of fall. Descriptive statistics, ANOVA and t-test were used to analyze differences in variables. Pearson correlation and multiple regression were used to investigate mediating and moderating effects of the fear of fall on the relationships between health belief on fall, fall-related knowledge, and fall prevention behaviors. Results: The fear of fall significantly mediated the health belief on fall and fall prevention behaviors, but there was no significant mediation between knowledge of fall and fall prevention behaviors. The fear of fall did not have a moderating effect on the relationships between health belief on fall, knowledge of fall, and fall prevention behaviors. Conclusion: It is important to investigate and implement health belief on fall and fear of fall among older adults to improve their fall prevention behaviors.

Purpose: The purpose of the study was to conduct a descriptive survey to examine the knowledge, infection prevention behaviors, and health beliefs regarding COVID-19 and to identify factors that influence infection prevention behaviors in elementary and middle school students based on the Health Belief Model. Methods: The study included 388 elementary and middle school students in Seoul, Gyeonggi, and Jeonbuk provinces. Data were collected from September 1 to September 15, 2023. The questionnaire consisted of 10 questions about COVID-19 knowledge, 13 questions about infection prevention behaviors, and 15 questions about health beliefs. The collected data were subjected to multiple hierarchical regression analyses. The cronbach's α of infection prevention behaviors was 0.83, the KR-20 of COVID-19 related knowledge was 0.68, and the Cronbach's α of COVID-19 related health beliefs was 0. 78. Results: In Model 1, females showed higher levels of infection prevention behaviors than males (β=.14, p=.006) and middle school students showed lower levels of infection prevention behaviors than elementary school students (β=-.10, p=.037). In Model 2, among COVID-19-related health beliefs, barriers had a significant negative effect on infection prevention behaviors (β=-.20, p<.001) and cues to action had a significant positive effect on infection prevention behaviors (β=.14, p=.037), indicating that lower barriers and higher cues to action were associated with higher levels of infection prevention behaviors. Conclusion: The results showed that prevention behaviors were associated with lower barriers and higher cues to action among COVID-19 health beliefs. Elementary and middle school students in Korea spend a lot of time in groups at private academies or school, which are closed spaces with poor ventilation, making them vulnerable to new infectious diseases such as COVID-19. Unlike adults, infectious diseases can have serious impact on their mental and social health. Therefore, it is necessary for schools to provide accurate and timely health education about COVID-19 to increase cues to action for elementary and middle school students in order to improve their infection prevention behaviors.

Recently, virtual reality (VR) and augmented reality (AR) technologies are attracting attention as core technologies in the era of the 4th industrial revolution. These virtual and augmented reality technologies are being used in a variety of industries, including the construction industry, healthcare industry, and manufacturing industry, to innovate in communication and collaboration, education and simulation, customer service and reinvention of the customer experience. In this paper, VR-based experiential safety education was conducted for workers of shipbuilding companies in Ulsan city, and for them, the educational effectiveness such as immersion, site applicability, safety accident prevention, education satisfaction, overall performance, and safety behavior in VR-based safety experience education were measured. In addition, we examined whether the immersion of VR-based safety experience education affects site applicability, safety accident prevention, educational satisfaction, overall performance, and safety behavior. Furthermore, it was analyzed whether site applicability plays a mediating role in the relationship between immersion and safety accident prevention. As a result, it was found that the immersion of VR-based safety experience education affects site applicability, safety accident prevention effect, education satisfaction, overall performance, and safety behavior, and that site applicability mediates between immersion and safety accident prevention. Based on these results, we suggests a direction for the development of VR-based contents in the field of safety and health and the transformation of safety and health education in the future.
