An analysis of worldwide incidents in chemical plants found multiple root causes and the lack of preventive measures was catastrophic. Therefore, the main objective of this study was to determine the factors contributing to and main predictive indicators for catastrophic incidents, such as fires and explosions, in the chemical plants. In this study, 94 accidents, including the incident investigation data reported by Chemical Safety Board for catastrophic incidents and recent domestic incidents at chemical plants, were reviewed. Common contributing factors were identified, and frequency analysis was conducted. Moreover, bow tie analysis was applied to determine the prevention and mitigation measures for each catastrophic incident. Accordingly, common contributing factors behind 16 categories of catastrophic incidents were derived and analyzed, and leading indicator candidates were presented in three priority groups. Presumably, the leading indicator can be used to determine what to prioritize in preventing catastrophic incidents in chemical plants.

This numerical study investigates the effects of the size of the natural smoke vent area (10% and 1% of the floor area) and the location of the fire source (i.e., at the side and center of the stage) on the temperature distribution in the compartment and velocity distribution and mass flow rate of flow through a natural smoke vent for a reduced-scale model of a theater stage. Then, the mass flow rate of outflow through the natural smoke vent in the event of a fire for a real-scale theater stage was examined. The case with the larger natural smoke vent area and central fire source location showed lower temperature distributions and higher mass flow rates of outflow and inflow than the case with the smaller natural smoke vent area and side fire source location. The trends of the temperature distributions were closely related to those of the mass flow rates for the outflow and inflow. Additionally, the case with the larger natural smoke vent area and central fire source location exhibited the most non-uniform flow velocity distribution in all cases tested. A bidirectional flow, in which the outflow and inflow occur simultaneously, was observed through the natural smoke vent. In the event of a fire situation in a real-scale theater stage, it was predicted that the case with the larger natural smoke vent area and central fire source location would have a mass flow rate of outflow that is 43.53 times higher than that of the case with the smaller natural smoke vent area and side fire source location. The present results indicate that the natural smoke vent location should be determined by considering the location in a theater stage where a fire can occur.

Circuit breakers are a crucial factor in ensuring the safety of a Direct Current (DC) grid. One type of DC circuit breaker, the Z-source DC circuit breaker (ZCB), uses a thyristor, which is a type of semiconductor switch. In the event of a fault in the circuit, the ZCB isolates the fault by generating a zero crossing current in the thyristor. The thyristor quickly and actively isolates the fault while generating a zero crossing current, but thyristor switch cannot control turn-off and the allowable current is lower than the current of the mechanical switch. Therefore, it is best to use a mechanical switch with a high allowable current capacity that is capable of on/off control. Due to the slow reaction time of mechanical switches, they may not isolate the fault during the zero crossing current time interval created by the existing circuit. In this case, the zero crossing current time can be increased by using the property that hinders the rapid change in the current of the inductor. This paper will explore whether adding system inductance to increase the zero crossing current time interval is a solution to this problem. The simulation of changing inductor and capacitor (LC) of the circuit is repeated to find an optimal change in the zero crossing current time according to the LC change and provides an inductor and capacitor range optimized for a specific load. The inductor and capacitor range are expected to provide optimization information in the form LC values for future applications of ZCB's using a mechanical switch.

To stem the ever-prevalent occurrence of industrial accidents in the construction industry, which is emerging as a social problem, efforts must be invested by various stakeholders. Specifically, among stakeholders, the orderer is at the top of a project's decision-making structure. Therefore, the orderer's awareness of safety and health directly affects the process of securing the safety of the overall construction site. In this light, the present study aims to identify differences in the perceptions of each stakeholder regarding the obligatory safety and health measures for clients that have recently been introduced. In addition, it suggests specific implementation plans in the Korean context. The data used for analysis were collected through a survey targeting stakeholders such as orderers, safety managers, and site managers, and the collected data were quantitatively reviewed by using multivariate analysis methods such as analysis of variance. As a result of the analysis, the introduction of safety and health obligations for the owner was found to be necessary, and the designation and operation of safety and health experts as an action plan was deemed reasonable. The authors expect that the results of this study can be used as basic data for revising the related regulations in Korea. Moreover, as a further study, a review of the effectiveness after improving regulations would contribute strongly to the domain.

The death rate in the construction industry, which is more than twice that of other industries, increases the need to solve chronic safety problems. In a situation in which the safety management measures that have been maintained thus far are unable to reduce construction accidents, the introduction of smart construction safety technology (SCST) that reflects the 4th industrial technology is required for the safety management of workers. Large corporations or public institutions have introduced SCST and are operating pilot sites, but SCST is still in its infancy and there have yet to exist field data regarding necessity and effectiveness. In this study, the concept of SCST, which has still to be established, is defined, and the actual condition of SCST was analyzed through a survey. Through the analysis of the necessity of SCST introduction, convenience, and effectiveness before and after its application, problems such as problems from the field point of view as well as other factors hindering the introduction of such technology are derived in detail. In addition, an effective combination of technologies for safety management at the current level is determined and an activation plan is presented.

Bridge engineering documents have essential contents that must be referenced continuously throughout a structure's entire life cycle, but research related to the quality of the contents is still lacking. XML schema matching is an excellent technique to improve the quality of stored data; however, it takes excessive computing time when applied to documents with many contents and a deep hierarchical structure, such as bridge engineering documents. Moreover, it requires a manual parametric study for matching elements' weight factors, maintaining a high matching accuracy. This study proposes an efficient weight-factor determination method based on an artificial neural network (ANN) model using the simplified XML schema-matching method proposed in a previous research to reduce the computing time. The ANN model was generated and verified using 580 data of document properties, weight factors, and matching accuracy. The proposed ANN-based schema-matching method showed superiority in terms of accuracy and efficiency compared with the previous study on XML schema matching for bridge engineering documents.

In Korea, companies which have work-related musculoskeletal burden works should have conducted legal risk assessments every three years from 2004 onwards. However, due to problems with the legal definition of work-related musculoskeletal burden works, some companies may have been exempted from the risk assessment even though their workers still experience work-related musculoskeletal pain. For example, the manufacturing process used by a particular semiconductor manufacturing company involved a great deal of legal musculoskeletal bueden works. However, this company eliminated the musculoskeletal burden works by continuously introducing automated processes, and finally, in 2016, all work which was legally defined as musculoskeletal burden work were removed from the company's manufacturing process. Nevertheless, in a 2016 survey, 9.6% of the company's workers still complained of musculoskeletal pain, and in a 2019 survey this proportion actually increased to 15.7%. This incident demonstrates the limitations and problems of the current legal risk assessment of work-related musculoskeletal burden work. Therefore, this study proposes two improvements to solve these problems. Firstly, it is necessary to broaden the current legal definition of work-related musculoskeletal burden works. For example, vibration risk factors and push/pull tasks that are currently missing from the definition should be included. Secondly, it is proposed that a survey on musculoskeletal pain should be conducted for all workers, regardless of whether they are engaged in musculoskeletal burden works. The results of this study could be used to improve the legal risk assessment of work-related musculoskeletal burden works.

The correlation between the Military Service Adaptation Test and the Biometric Index is studied herein with the aim of preventing military safety accidents. The subjects were 36 soldiers under the age of 25 years. Based on the results of the service adaptation test, the soldiers who did not adapt to the service were distinguished. First, there was a significant difference in brain stress among the brain wave indicators of the general group and the group of interest. Second, the higher the left and right brain imbalance index among the brain wave indicators, the higher was the level of empathy shown by the subjects. Third, among the pulse indicators, the subjects with high cumulative fatigue levels were found to have high levels of emotion (anxiety, depression, physicalization) and relationship isolation (indifference, sensitivity). Based on these results, the implications of this study and suggestions for future research are discussed.

The study measured a subway construction worker's Macpa stress by Heart Rate Variability measuring instrument and conducted a survey of Korean job stress from subway construction workers. Also, the study analyzed the relationship between Macpa stress index and Korean job stress result and suggested managing stress method for each item. According to National Statistical Office data, the first line subway in Seoul was started to open in 1974. The extended total length is 996 kilometers until 2019. Many aged workers are currently working at subway construction sites due to the avoidance of young workers since the past until now. It means that the elderly has a substantial portion among subway construction workers. The productivity has been adversely affected by health problems due to the aging of workers, job stress due to heavy work, and personal health problems. So, the regulation and policies on job stress health management are being strengthened. The data were measured Macpa stress by machine measuring heart rate variability and conducted Korean job stress survey(shortened) from Sa-sang to Ha-dan line Busan subway construction workers for analyzing the relationship. Independent variable were age, job duration, job position, employment type, working type in this study. Macpa's dependent variable was stress index and Korean job stress survey(shortened)'s dependent variables were job requirements, job autonomy, relationship conflict, job instability, organizational structure, inappropriate compensation, working place culture, and total score. SPSS 12.0 K Statistics Program was used for statistical analysis. Kruskal-wallis test, a nonparametric statistical analysis, was used because the data are difficult to be assumed as normal distribution. As a result, the paper indicated the significant correlation between Macpa stress index and Korean job stress(short version). The elderly workers presented higher Macpa index and higher job stress due to aging and heavy-duty work. The majority workers were daily workers who had unstable working condition and uncertainty about the future. The study suggested a manual that could reduce job stress for subway construction workers and future study deriving management tool through analyzing job stress factor is necessary.

The total number of Korean restaurants using delivery applications has substantially increased from 7.6% in 2018 to 11.2% in 2019. In 2020, the gross sales in the food delivery service market reached approximately 17 trillion won; this amount is virtually six times that in 2017 (i.e., 2 trillion won). Meanwhile, the annual average death toll of motorcycle riders increased by 3.5%, whereas the number of deaths due to other traffic accidents decreased by 8.2%. Consequently, the foregoing has become a critical social problem. Despite the continuing increase in the number of delivery riders due to the rapid expansion of the delivery industry, no appropriate safety management system has been established. Moreover, the government is experiencing difficulties in assessing the exact situation because of the absence of competent authority. In this study, fundamental data on the characteristics of delivery work and motorcycle accidents were collected through surveys and interviews; then, the influencing factors of traffic accidents were analyzed. Different influencing factors were identified: work experience as a rider; number of deliveries; whether to accept delivery requests in transit; manner of accepting delivery requests; and traffic law violations, such as speeding (for faster delivery) and running a red light. Because the motorcycle delivery industry has a relatively low job-entry barrier (i.e., special qualifications are not required), the riding skills of riders must be improved, and delivery companies must be technically developed to achieve a safe working environment. The results of this study can be utilized as fundamental data for system development or structural improvement of the delivery industry.

In the risk assessment of urban railway systems, a hazard log is created by identifying hazards from accident and failure data. Then, based on a risk matrix, evaluators analyze the frequency and severity of the occurrence of the hazards, conduct the risk assessment, and then establish safety measures for the risk factors prior to risk control. However, because subjective judgments based on the evaluators' experiences affect the risk assessment results, a more objective and automated risk assessment system must be established. In this study, we propose a risk assessment model in which an adaptive neuro-fuzzy inference system (ANFIS), which is combined in artificial neural networks (ANN) and fuzzy inference system (FIS), is applied to the risk assessment of urban railway systems. The newly proposed model is more objective and automated, alleviating the limitations of risk assessments that use a risk matrix. In addition, the reliability of the model was verified by comparing the risk assessment results and risk control priorities between the newly proposed ANFIS-based risk assessment model and the risk assessment using a risk matrix. Results of the comparison indicate that a high level of accuracy was demonstrated in the risk assessment results of the proposed model, and uncertainty and subjectivity were mitigated in the risk control priority.

Hydroelectric power generation is currently gaining popularity as the core of the eco-friendly energy and power sector, and a large number of hydroelectric power generation facilities are in operation both at home and abroad. Failures or abnormalities in hydroelectric power facilities occur for various reasons, and studies on condition monitoring to prevent them have been actively conducted in recent years. Furthermore, this study extracted key terms from domestic and foreign hydro-turbine monitoring related data using R-studio text mining for the aim of proposing guidelines for the hydro-turbine facility condition monitoring system and used them to construct and analyze the most recent detailed data. Big data was constructed and analyzed by examining the most recent detailed data, such as sensors types and abnormal phenomena that can be detected by sensors. The HCMS (Hydro-turbine Condition Monitoring System) guideline table summarizes the analyzed contents and shows the status of hydro turbine facility condition monitoring using sensors in two ways: facility component standards and sensor standards. If the table is used, it will provide convenience and efficiency in determining the sensor type to use for condition monitoring, attachment location, and target components, as well as aid in the initial design of the hydro-turbine facility condition monitoring system.

Various composite materials are being used to realize light weight and high strength throughout the industry. Fiber-reinforced composites differ in strength and application range depending on how the fibers are weaved. In addition, defects may occur in the fibers depending on the temperature and pressure of the molding conditions. These defects result in a variety of fracture mechanisms, typically due to interlayer fracture. There has been a lot of research on interlayer fracture of plain CFRP composite materials, but there is a lack of research on GFRP/CFRP laminating hybrid composite of twilled weave structure with excellent resistance to fibrous deformation compared to plain weave. In consideration of this reality, a mode Ⅱ fracture test was performed by making GFRP and CFRP of twilled structure into 4ENF specimens by applying the molding conditions used in manufacturing products in industrial sites. As a result, the energy release rate and the stress intensity factor tended to decrease as the initial crack length increased.

This study analyzes the validity of the design allowable compressive stress suggested in the design standards of the new material vertical members in system scaffolds and system supports through experiments. The experimental results were compared with the design allowable compressive stress presented in the design standards for steel structure members (KDS 14 30 10), steel bridge design standards (KDS 24 14 30), and road bridge design standards. As a result of comparing the design formula and the experimental results for the vertical members of the system scaffold, experimental results were found to be similar to the design allowable compressive stress calculated from the road bridge design standard. For the vertical members of the system support, the experimental maximum compressive stress considering the safety factor in all specimens was smaller than the allowable compressive stress suggested in the design criteria. The case, in which the difference between the experimental value and the design standard allowable compressive stress is the smallest is the steel bridge design standard. As the slenderness ratio is relatively large, the difference between the experimental value and the design allowable compressive stress was significant.

Facility-related safety failures such as the collapse of 00 Bridge currently under construction and the determination of the lowest safety rating for a large-sized building in Gangnam continue to occur. In the ready-mixed concrete industry, illegal acts such as the use of unapproved cheap materials to cut back on the cost due to the growth slowdown in construction industry or reduction of cement volumes by deceiving the approved specific mix are being caught by police every year, leading to serious problems in concrete quality. To solve these problems, this study developed a structure traceability management system that inputs all the information including raw materials used for concrete, manufacturers, placing environments, and quality test result values in real time and manages them in a form of electronic document. To set up this system, a method of managing the present conditions from mixing design to placing was reflected through electronic documents. In order to secure reliability for concrete quality tests, a function that converts photographed test results into electronic documents using the mobile O.C.R (Optical Character Recognition) was developed, which is currently applied to 80 domestic construction sites in Korea. After the set-up, 9,735 mixing-design data and 10,025 quality test data have been stored as electronic documents in the 80 construction sites for 14 months. Additionally, the time to prepare documents according to the quality test was reduced by 74% from the previous 238 minutes to 62 minutes, proving the effectiveness in work efficiency. Data managed with these electronic documents will utilize a big data system and be helpful in identifying optimal mixing designs, structures, and structural forms of ready-mixed concrete by region.

This study was conducted to examine the influence of risk perception (knowledge and dread) of fine particles on protection behaviors. In addition, the mediating effects of risk attitude between risk perception and protection behaviors were examined. Survey data were collected from 449 people of different age groups employed in a variety of organizations and a hierarchical regression was conducted to evaluate a hypothesis. The obtained results indicated that risk perception has a positive relationship with risk attitude and protection behavior. Knowledge; a sub-scale of risk perception, was positively correlated with the risk attitude but not significant with the protection behavior. However, the other sub-scale; dread, was positively correlated with both risk attitude and protection behavior. Furthermore, multiple regression analysis revealed that both knowledge and fear have a significantly positive effect on risk attitude and that dread is more influential on the risk attitude than the knowledge. However, only dread has a significant effect on protection behavior. In addition, risk attitude mediated the relationship between the dread for fine particles and response behavior completely. Additionally, the implication and limitations of this study were discussed.

In this study, the factors affecting the psychological damage of disaster victims were explored using the “Long-term survey on the change of life of Disaster victim” data constructed by the National Disaster Management Research Institute. The obtained results were utilized to suggest a recovery plan for psychological damage caused by disasters. The data used for the analysis included the survey data of disaster victims who consecutively participated in the survey in 2019 and 2018. To examine the factors that affected the post-traumatic stress level experienced by the disaster victims at the time of the survey, after controlling the post-traumatic stress level in the patients in 2018, factors affecting the post-traumatic stress level in 2019 were explored. The independent variables included age, gender, years after disaster, perceived scale of damage, resilience, social support, and community resilience. Further, the effects of the variables was examined using stepwise regression analysis. The analysis result revealed that the effect of these variables was in the order of resilience, community resilience, age, perceived scale of damage, and year after disaster. In addition, gender and social support level were excluded from the regression model. The result indicates that the symptoms of post-traumatic stress reduce with an increase in the resilience of the victims and the community resilience. In contrast, post-traumatic stress symptoms were enhanced with an increase in age and perceived scale of damage. Therefore, to reduce the consequence of psychological damage caused by disasters in the future, it is essential to develop an approach that can increase the resilience of disaster victims and enhance the resilience of the community to disaster. In addition, it is necessary to approach disaster psychological recovery support from a long-term perspective based on the age and damage scale.

To achieve aviation safety, we need to understand and maintain the interrelationships between people, machines, and components of the environment. The Safety Management System, which applies to the military and the private sector, is intended to focus on risk management including risk assessment and risk controls. An analysis of the Safety Management System risk management practices of Incheon International Airport Corporation, the Korean Air Force, and the U.S. Army Aviation was conducted and we sought to apply the results to Korean Army Aviation. Korean Army Aviation is a military department under the Army, so regulations and guidelines for the safety risk assessment are not widely available. Therefore, we supplemented organizational composition and institutional aspects to conduct the risk assessment. The risk assessment was divided into four main stages: preparation, identification of risk factors, estimation and determination, and risk reduction measures. Risks were identified, analyzed, and evaluated based on Army Aviation risk factors then those risks were reduced to an acceptable level. Risk factors included weather conditions, aircraft conditions, and the pilot's physical and mental conditions that directly affect helicopter operation. Likelihood of occurrence and severity criteria were selected with consideration of the characteristics and environment of Army Aviation. Based on this scoring, estimation of risk was determined and analyzed against the risk acceptance criteria. If a risk is considered unacceptable, risk control measures are required to reduce the risk to an acceptable level in order to achieve aviation safety.

The risk of flooding is increasing due to global climate change, increasing the importance of river facility safety. River facilities are essential to preventing floods. To reduce human and property damage that may occur due to floods, the maintenance and management of river facilities is required. In Korea, river facilities whose age exceeds 30 years account for more than 40%, indicating that the risk of facility deterioration may rapidly increase in the future. In this study, a performance evaluation model that can predict the performance of river facilities for the preemptive maintenance of river facilities was proposed and used in hydraulic gate calculations. A regression analysis was performed based on the results of the precise safety diagnosis in the FMS (facility management system) to derive the change in the performance index according to the age of the hydraulic gate. The optimal regression equation was selected after comparisons with previous studies, and the performance evaluation model was used to determine the relative effect of maintenance for each river. The model is expected to be useful to river managers for determining the maintenance effectiveness or prioritizing budget input.

Recently, damages due to floods have increased because of abnormal climate. Therefore, It is necessary to implement systematic and scientific maintenance to reduce flood damage in rivers. Floods aggravate human life and damage or collapse river facilities. Therefore, it is necessary to implement safety management for aging river facilities during floods. As the facilities deteriorate, maintenance costs increase, and it is very important to inspect and maintain facilities at the appropriate time to avoid major accidents. Systematic management of river facilities and their environment and informing people involved in riverside activities are important to protect the public from natural disasters such as floods, droughts, etc. Therefore, a simple information service is not enough, and the development of customized technology providing information according to the users' needs is emerging. In this regard, it is important to develop a system that can unify management and integrate information about river facilities and their environments. In this study, a river facility management business support system was developed, which enables the integrated maintenance of facilities. The management support systems are expected to provide insightful information to decision-makers when making decisions such as budgets to invest in facility maintenances.
