Hydrofluoric acid leakage accident was occurred on Dec. 2012 in Hube Global. That accident has bought many changes of response in national organizations. Chemical companies respond quickly even when small quantities leakage of chemicals and response agencies were put a lot of manpower and equipment in incident response. Incident response to the response activities of the agents is difficult if the accident substance was not identified. Unknown chemicals can be generated by the water for fire-fighting during the emergency response process. In this case, an additional information was needed for response of chemical accident to prevent of great damage. In this study, we investigated the improvement of chemical accident information by extraordinary chemical accident.

As a part of NERI:;, Truck Shipment Safety Information is divided into Optimal Route Guidance system and Emergency Response system. This study which is for developing of Truck Shipment Incident Emergency Response System intends to prevent or early response damage caused by incidents through realtime monitoring about the position and the state of Hazard material transport truck. For this, we divide it into three scenarios; realtime monitoring, management of incidents, information provision to related organizations and present functional requirements and architecture coming with each scenario. As a result of the first step among total three steps, it would able to not only realtime management of trucks but also guide for auto-enforcement or management about illegal act like dumping scrapped material. It is now under examination about position of detection and technology of communication to application. From now on, it is expect to test in the range of Metropolitan after selecting appropriate technology.

Introduction: An unexpected death was reported in a beginner immediately after starting the work at a plating factory. After the incident, air sampling was performed using a simulation of the situation as it had been at the time. Methods: To evaluate the airborne concentration of hydrogen cyanide, a total of six samples were collected: one personal sample, three area samples, and two background samples (office and outdoors). Hydrogen cyanide measurement was performed according to the standard sampling protocol recommended by the U.S. NIOSH (National Institute of Occupational Safety and Health). Results: The highest concentration of hydrogen cyanide was 0.938 ppm measured in a sample collected from the plating bath area with local exhaust ventilation. This value was approximately 20% of the ceiling occupational exposure limit. The personal sample showed a concentration of 0.135 ppm. Samples collected near the bath in which the incident occurred and a dehydrator showed hydrogen cyanide concentrations of 0.236 ppm and 0.101 ppm, respectively. Hydrogen cyanide was not detected in the background samples (office and outdoors). Conclusions: It is necessary to use proper ventilation systems and respirators in plating factories to prevent acute poisoning. Furthermore, it is important to educate and train new workers dealing with toxic substances.

Purpose: This study was conducted to analyze job stress, ego-resilience, and results of the impact of event scale in order to verify the actual job stress of firefighters and provide baseline data for developing resolution programs. Methods: Data were collected via e-mail from 270 firefighters working at 119 safety centers and firehouses in the regions of Gyeonggi, Chungcheong, Busan, and Gyeongsang-do between the $1^{st}$ and $30^{th}$ of July, 2017. Results: Regarding gender differences in job stress, women ($2.16{\pm}0.65$) showed statistically significant job stress compared to men ($1.93{\pm}0.57$). As for the results of the incident impact of event scale statistically significant differences were observed (p=.001), and ego-resilience in men ($4.15{\pm}0.54$) was significantly higher than that in women ($3.79{\pm}0.75$) (p=.006). Depending on the work period, there were statistically significant differences (p=.000) in job stress, ego-resilience (p=.002), and impact of event scale (p=.000). Conclusion: Since job stress, ego-resilience, and results of the impact of event scale were closely related to dispatch frequency and work period of the firefighters, detailed and continuous stress management programs that consider these factors need to be developed.

Marine Incidents based on Heinrich's law are very important in preventing accidents. However, marine Incident data are mainly qualitative and are used to prevent similar accidents through case sharing rather than statistical analysis, which can be confirmed in the marine Incident-related data posted in the Korea Maritime Safety Tribunal. Therefore, this study derived quantitative results by analyzing the causes of marine incidents during berthing using various methods of statistical analysis. To this end, data involving marine incidents from various shipping companies were collected and reclassified for easy analysis. The main keywords were derived via primary analysis using text mining. Only meaningful words were selected via verification by an expert group, and time series and cluster analysis were performed to predict marine incidents that may occur during berthing. Although the role of an expert group was still required during the analysis, it was confirmed that quantitative analysis of marine incidents was feasible, and iused to provide cause and accident prevention information.

The recent "Log4j Security Vulnerability Incident" has occurred, and the information system that uses the open source "Log4J" has been exposed to vulnerabilities. The incident brought great vulnerabilities in the information systems of South Korea's major government agencies or companies and global information systems, causing problems with open source vulnerabilities. Despite the advantages of many advantages, the current development paradigm, which is developed using open source, can easily spread software security vulnerabilities, ensuring open source safety and reliability. You need to check the open source. However, open source vulnerability scan tools have various languages and functions. Therefore, the existing software evaluation criteria are ambiguous and it is difficult to evaluate advantages and weaknesses, so this paper has developed a new evaluation criteria for the vulnerability analysis tools of open source

The dental accidents and disputes among Korean dentists have been on the increase with time. The main purpose of this study is to figure out the actual status of the dental accidents and malpractice disputes based on a questionnaire survey. The findings showed that 64.8% of respondents had been experienced the dental accidents, and 52.9% of respondents had been locked into the disputes. Within 5 years from the start of dental practice, the nearly half of the dentists responded the experience of the dental accidents and disputes. The amount of compensation for dental accidents and disputes wereindentalimplant, prosthodontics, and oral surgery treatments in descending order. The highest incident type was wrong process/treatment/procedure problem in clinical process/procedure.

As a dependency on Global Navigation Satellite System (GNSS) becomes increase in various applications, its reliability has been very important. However, in South Korea, Global Positioning System (GPS) jamming incident happened four times since 2010. GNSS signal is so weak that it is highly susceptible to all types of the jamming. GNSS jamming can cause serious damage in the safety-critical applications based on the GNSS. In this paper, we present the GNSS jamming signal propagation prediction simulator based on ITU-R P.1546 model. This simulator is developed for preventing or reducing the damage from the GNSS jamming attack by predicting the jamming propagation strength based on the geographical information in Korean peninsula.

Distributed Denial of service attack is one of the major threats nowadays especially to the government infrastructure that give huge impact to the reputation and interrupt the services and resource. Our survey start with brief introduction about DDoS attacks, we illustrate the trends and incident happened at government from various countries. We then provide an extensive literature review on the existing research about implication, types of attacks and initiative to defence against the DDoS attacks. Our discussion aims to identify the trends in DDoS attacks, in depth impact of DDoS attacks to government infrastructure, classification of attacks and techniques against the attacks. And we will use for a fire fight safety and management.
