This study examines the risks posed by the on-site reactivity of hazardous chemicals, focusing on high-risk accident scenarios and response system improvements. Using cases like TATP and VX, it analyzes the accessibility and combination potential of precursor chemicals that are not inherently hazardous but can become highly dangerous under specific conditions. Scenario-based qualitative risk assessments reveal critical gaps in South Korea’s current safety management, including insufficient anticipatory regulations, limited detection capabilities for reactively synthesized agents, and fragmented inter-agency coordination. The study highlights the need for a proactive, integrated approach incorporating real-time precursor tracking, advanced detection technologies, and joint scenario-based response training. By shifting from static substance control to risk-based preparedness, this research offers strategic recommendations for enhancing chemical accident prevention and response in complex facility environments.

This study aims to identify potential problems arising from the application of the Serious Accidents Punishment Act (SAPA), enforced in January 2022 to prevent serious industrial accidents in South Korea, to workplaces with 5 or more but less than 50 employees starting in January 2024. These smaller enterprises often face challenges such as limited safety-related budgets, and constraints in safety organizations and personnel. To address these concerns, a survey was conducted targeting CEOs of businesses with fewer than 50 employees, focusing on their understanding of SAPA and the establishment of countermeasures. Based on the survey results, this study seeks to propose viable alternatives and solutions for these businesses.

Before the fire brigade arrives at the scene, the fastest way for occupants to suppress a fire is by discharging water through indoor hydrant outlets equipped with electronically controlled valves or motorized valves, as these systems are designed to open automatically. The experimental results are as follows: (1) Regarding electronically controlled valve operation times, system A had the shortest activation time of 6.74 seconds after the fire signal, while system J recorded the longest time at 13.4 seconds. (2) For angle valves (older model), system A had the shortest operation time of 10.2 seconds, whereas system I recorded the longest at 17.8 seconds. (3) For angle valves (newer model), system A again had the shortest activation time of 10.2 seconds, while system I recorded the longest at 17.8 seconds. (4) For motorized valve operation times, system A had the shortest activation time of 3.81 seconds, and system I the longest at 6.55 seconds. The observed differences in operation times are attributed to the fact that angle valves require manual operation by occupants, causing delays and slower valve opening, which increases activation times. In contrast, electronically controlled valves and motorized valves operate automatically, resulting in significantly shorter activation times.

The purpose of this study is to measure and analyze the number of chest compressions, chest compressions, depth of chest compressions, ventilation, duration of interruption, and accuracy in college students when eyewitness cardiac arrest occurs. The results of the experiment are as follows.(1) The result of the difference in the number of chest compressions was that A was a 20-year-old woman with an average of 114 chest compressions. E was a 22-year-old man with 96 chest compressions, and J was a 24-year-old woman with 109 chest compressions. (2) The result of the difference in chest compressibility depth was that A was a woman in her 20s with an average chest compression depth of 5.0 to 5.2 cm, E was a man in his 20s with an average chest compression depth of 5.0 to 5.4 cm, and J was a woman in her 20s with an average chest compression depth of 5.1 to 5.5 cm. (3) Ventilation was performed for A, E, and J. (4) CPR discontinuation time (second) was performed for a 20-year-old woman for 0 seconds, E was for a 22-year-old man for 5 seconds, and J was a 24-year-old woman for 5 seconds or less. (5) CPR accuracy was found to be 95.2% for a 20-year-old woman, E was found to be a 22-year-old man for 79.6% for a 22-year-old man, and J was found to be 86% for a 24-year-old woman on average. In order to properly cope with an emergency situation in which cardiac arrest occurs, it is confirmed that CPR practice should be sufficiently performed in advance to improve the accuracy of cardiac pressure, and CPR should be performed when cardiac arrest patients occur by maintaining skills through steady retraining.

The purpose of this study, when predicting acute oral toxicity using QSAR software, the reliability of the predicted values was studied according to a single functional group or multiple functional groups within a single chemical. Acute oral toxicity is predicted using EPA T.E.S.T S/W for chemicals registered in ChemIDplus. The effect of a combination of specific functional periods on the degree of consistency of predicted values was studied. When some specific functional groups (combinations) exist, it was confirmed that the experimental and predicted values were high and low. It was confirmed that the prediction accuracy was high when the Anion group and the Halogen group were together, and the perdiction accuracy was significantly low when the Nitrile group was present. As a result of accumulating such data and showing reliability in predicting acute oral toxicity with EPA T.E.S.T S/W for 10 SVHC substances without experimental values, the matching rate was derived from at least 0% to 73.33%. It was confirmed that there was some tendency of the QSAR prediction value according to the combination of specific complex functional groups. When 10 SVHC substances without experimental data were predicted to be toxic through T.E.S.T S/W by quantitatively databaseizing the above tendency, 0~73.33% of the results were derived as a result of showing the realiability of the program prediction

Stroke is one of the major causes of death worldwide, and in Korea, it has the second highest mortality rate after cancer. Stroke patients require continuous observation and rehabilitation treatment after onset, and in particular, paralysis symptoms are likely to worsen during rehabilitation, emphasizing the need for a real-time monitoring system. Meanwhile, the importance of medical data quality control (QC) algorithms is increasing. In this study, various causes such as failure of sensors such as voltage, current, and temperature of the patient's imaging device diagnostic device, or power loss, may cause malfunctions and transmit inaccurate data. Therefore, in order to secure the reliability of the patient's imaging device diagnostic device data, we plan to design data analysis and algorithms based on QC data of the imaging device diagnostic device. In order to design data analysis and algorithms based on QC data, a system capable of measuring and analyzing sensor data of imaging device diagnostic equipment was built. The reference values of the algorithms to be developed, such as physical limit tests, continuity tests, step tests, median filter tests, and frequency distribution tests, were derived. Voltage, current, and temperature sensor data were statistically analyzed, and in the case of analysis that changes in real time, algorithm S/W was inserted to calculate in real time. It is judged that by monitoring in real time, efficient management and maintenance of the device, and rapid response to device failures will be possible. In the case of device failure, various accidents and high costs can occur. Therefore, if real-time failures are confirmed and rapid maintenance is possible, maintenance costs can be reduced and reliability can be improved, so it is judged that efficient management of the device will be possible.
