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.

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 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.
