Unlike research focused on existing technologies and individual errors to analyze the causes of incidents, this study approached them from an organization and culture. And this study is not a one way study but cyclical study what can track cause down using causal loop diagram methodology. Four diagnostic criteria for the negative state of the safety culture : secretive, blame, failure to learning, and incremental learning, combine literature study and expert opinion to derive 41 variables. Connecting these variable make 4 causal loop diagrams and total causal loop diagram. Case accumulation in secretive, accident report in blame, knowledge accumulation in failure to learning, near miss discovery in incremental learning are the main variables. Safety incident is the objective variable by classifying them into 4 stages in total loop, leading track as the most affect is case accumulation, and Step 4 as you can see accident report and near miss discovery are the result of tracking down the cause. This study can be used as a basis for improving the management priority and the system in incident prevention.

Background: The relationship between risk factors and likelihood of occupational injury has been studied. However, what has been published has only provided a limited explanation of why some of the employees working in the same environment as other employees suffered a single-injury event, while other employees experienced multiple-injury events. This article reports on an investigation of whether artisanal and small-scale miners in Migori County of Kenya are susceptible to a single-injury or multiple-injury incidences, and if so, what underpinning parameters explain the differences between the single incident injured and the multiple incident injured group. Mine management commitment to safety in artisanal and small-scale mining (ASM) operations is also considered. Materials and methods: The research objectives were achieved by surveying 162 uninjured and 74 injured miners. A structured, closed-end questionnaire was administered to participants after the stratification of the study population and systematic selection of the representative samples. Results: The results showed that most injured miners suffer a single-injury incident rather than experiencing multiple-injury events, and laceration (28.40%) was the common injury suffered by the miners. The analysis showed that the risk factors for the single incident injured group were not similar to those in the multiple incident injured group. The research also found mine workers have low opinion about mine management/owners commitment to safety. Conclusion: The study concluded that mine management and miners need to be educated and sensitized on the dangers of this operation. Provision of safety gears and positive safety culture must be a top priority for management.

Purpose : The purpose of this study was to examine the mediating effect of perceptions regarding the importance of patient safety management in the relationship between incident reporting attitudes and patient safety care activities for nurses in small-and medium-sized general hospitals. The objective was to provide a basis for planning tailored training programs aimed at improving patient safety care activities. Methods : This study was conducted with 187 participants in small- and medium-sized general hospitals in K city in South Korea from March 15 to March 31, 2019. The data collected from participants were analyzed using descriptive statistics, a t-test, ANOVA, Pearson's correlation coefficients, and a multiple regression using IBM SPSS/WIN 21.0 software. Results : Patient safety care activities were found to be correlated with incident reporting attitudes (r=.27, p < .001) and perceptions of the importance of patient safety management (r=.59, p < .001). Further, perceptions of the importance of patient safety management had a complete mediating effect (${\beta}=.409$, p < .001) on the relationship between incident reporting attitudes and patient safety care activities. Conclusion : Based on the findings of this study, tailored training programs regarding patient safety care activities focused on boosting perceptions of the importance of patient safety management are highly recommended to improve nurses' patient safety care activities in small- and medium-sized general hospitals.

An experimental technique for determining the spalling strength of rock-like materials under a high strain rate is developed. It is observed that the spalling strength of a specimen can be determined by only knowing the wavelength, loading peak value and length of the first spallation of an incident wave under a specific loading waveform. Using this method in combination with a split-Hopkinson pressure bar (SHPB) and other experimental devices, the spalling strength of granite specimens under a high strain rate is tested. Comparisons with other experimental results show that the new measuring method can accurately calculate the dynamic tensile strength of rock materials under a high strain rate.

Purpose: The purpose of this study was to analyze the trends and characteristics of infection-related patient safety incident reporting before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and to provide basic data for preventing infection-related patient safety incidents and improving their management. Methods: A cross-sectional analysis of secondary national data (Patient Safety Reporting Data) was conducted. In total, 517 infection-related patient safety incidents reported from 2018 to 2021 were analyzed. Changes in the number of reports before and during the COVID-19 pandemic and differences in variables related to infection-related patient safety incidents were analyzed using the chi-square test and independent t-test in SPSS 29.0. Results: This study found that infection-related patient safety incidents decreased during the COVID-19 pandemic compared to before the pandemic. Furthermore, incident-related characteristics, such as the type of healthcare organization, severity of harm, and post-incident actions, changed during the COVID-19 pandemic. Conclusion: The many changes in the infection control system and practices during the COVID-19 pandemic may have contributed to a decrease in the reporting of infection-related patient safety incidents. It is hoped that longitudinal studies on patient safety incidents related to the pandemic and analytical studies on factors influencing patient safety incidents will continue to be conducted to prevent and improve patient safety incidents.

PURPOSES : This study aims to investigate the direct and indirect influence areas from incidents on urban interrupted roadways and to develop traffic management strategies for each influence area. METHODS : Based on a literature review, various traffic management strategies for certain incidents were collected. In addition, the relationship between the measure of effectiveness and the characteristics of incidents was explored using an extensive simulation study. RESULTS : From the simulation studies, traffic delays increased as the number of lane closures increased, and the impact of lane closures was reduced to the direction upstream from the incident site. However, the magnitude of the delay change depended on the degree of saturation. Using these characteristics, the direct and indirect influence areas resulting from incidents were defined, and traffic management strategies were established for each direct and indirect influence area and for each level of incident. CONCLUSIONS: The results of this study will contribute to the improvement of national traffic safety by preventing secondary incidents and by effective adaptation to incident events.

Aerial working platform is recently used broadly in heavy industry and construction field and also the utilization of it is growing. However, the raise of critical incident caused by unskilled operator is increasing gradually. To reduce and prevent such incident, the training for operating is essential. It's not easy to cover the requirements for the training with real platform because of the high price of it, safety and weather condition. This paper proposes a simulator for the training based on virtual reality to give the training safely regardless to the weather condition and the simulator is deliverable in lower price than real one. The simulator proposed in this paper is available to be set according to the level of trainee managing the assessment level and be also applied for the design of general heavy equipment training simulator based.

Background: Fisheries and aquaculture are statistically acknowledged to be among the most dangerous occupations. Yet, industrial safety and health precautions against occupational accidents within the sector are not sufficiently implemented in many parts of the world. The present study aims to provide a quantified overview of work accident statistics in the Turkish fisheries and aquaculture industry. Methods: This article presents an overview of reported injuries and fatalities in the Turkish fisheries and aquaculture industries from 2006 to 2020. Incident, permanent incapacity, and fatality rates were calculated, and the difference between fisheries and aquaculture was statistically examined. Results: The overall incident, permanent incapacity, and fatality rates were 449.4, 4.7, and 5.7 per 100,000 worker years, respectively, over the 15-year period. With these fatality rates, fisheries and aquaculture are two of the industries with the highest fatality rates among comparable industries in Turkey. Incident rates in fisheries and aquaculture indicated that aquaculture work is more dangerous and risky. The data set includes 25 fatalities and 22 permanent incapacity cases over 15 years and shows an increase in fatality rates and occupational accidents in the last 8 years. Conclusion: present study showed that the quality of data and reporting in the Turkish fisheries and aquaculture industries including occupational illnesses, must be improved in order to be more preventative and to develop efficient safety management in the sector. Incentives for providing thorough data on occupational incidents must be enhanced to improve occupational safety awareness in Turkish fisheries and aquaculture.

Lack of incident reporting culture has been pointed out as a potential risk factor across industries. Consequently, comprehensive understanding of the factors affecting the willingness to report (WTR) is necessary. However, our knowledge on the related studies are not enough to date and even most parts of the existing studies have focused on patient safety, which makes it difficult to universally apply the factors to all industries. Therefore, this study aimed to identify WTR factors in chemical plants and evaluate the influence degree of the factors. To do this, 45 candidate factors were summarized throughout the previous studies and surveying plant safety staff. A questionnaire survey was conducted for 614 all employees from 9 chemical plants which belong to one company, and finally 32 WTR factors were identified throughout 520 responses. Of these, 19 factors were consistent with the previous studies and 13 factors were newly identified. The most influential factor was 'Views on the necessity of incident reporting', and 'Reporting practice by outcome severity', 'Fear of vilification, conflicts, blame, or sanctions' were followed. This result not only suggests various WTR factors suitable for chemical plants, but also shows need to derive specific factors that are appropriate to each industry. An empirical study could be expected to increase incident reporting by using these factors and verify its effectiveness on injury rate.
