Carbon black is a material in the form of fine black powder obtained by incomplete combustion or pyrolysis of hydrocarbons, and is composed of 90-99% carbon, and the rest is composed of hydrogen and oxygen. In the event of an emergency during the manufacture of carbon black, the generated tail gas should be safely discharged through an emergency line to prevent fire, explosion, and environmental pollution accidents caused by the tail gas. If the pressure continues to rise, the pressure control valve shall operate and the rupture plate shall be ruptured sequentially and the tail gas shall be discharged to the vent stack through the emergency line. As an emergency emission system, even if some untreated substances in the tail gas are released into the atmosphere, they are lighter than air, so it is safe to discharge them to a safe place through the Vent Stack. If the gas pressure is rising or worse, it is discharged from the Vent Stackine, and discharging fuel.

This study clarifies the simulation on freezing of remaining water in the Z-trap set up in the PVC sewage bay to control malodor. It made use of commercial FEM LAB program(ver. 3.2) well known as a solution of the problems arising in the flow of various fluid, heat transfer and mass transfer. Simulation results under the temperature $-20^{\circ}C$ outwards show that the water in the Z-trap set up in the sewage bay to control malodor freeze in the 60cm under the ground level after 14 days in the wet ground, and after 17 days in the regular ground. On the other hand, if the soil is dry even after the 42 days does not go down below freezing. Therefore, the water in the Z-trap was confirmed that it does not freeze.

Purpose: The purpose of this study was to examine the safety awareness and safety behaviors of personal assistant for visual impairments. Method: This study was targeted at 263 personal assistant for blind people from May to June 2021. Research subjects who wished to participate in the study expressed their intention to participate through the recruitment documents and gave written consent before participating in the study. Result: First, the safety awareness and safety behavior were high among the personal assistants who had practical fire extinguisher practice experience and education on how to act in a disaster situation. In addition, when the emergency rescue method was educated, the life safety awareness and fire safety awareness were high, but there was no difference in the awareness of disaster safety, and the safety behavior was higher. Third, the higher the life safety awareness, fire safety awareness, and disaster safety awareness of personal assistant for the visually impaired, the higher the safety behavior. Conclusion: This study revealed that it is important to provide appropriate safety education to personal assistant and implement a program to raise safety awareness so that the visually impaired can live a safer life.

최근 들어 재난이 빈발하여 우리의 안전을 위협하는 상황이 심해지고 있다. 그래서 본 연구는 이에 대한 대책 연구가 시급하다는 관점에서 이루어졌다. 기존 연구를 개관해 보면, 주로 재난의 발생 원인과 사후 대책을 많이 다뤄왔는데, 창의성에 대해서는 거의 다루지 않았다. 그런데, 실제 재난은 동일한 형태로 반복되기보다는 매번 그 원인, 진행 과정, 피해규모, 대응과 해결방안 측면 등에서 새로운 형태를 띤다. 이러한 상황에서는 재난을 예방하고 구조하고 복구하는 기관 담당자뿐만 아니라 피해당사자도 대책 매뉴얼을 초월하는 창의성을 많이 가져야 한다. 이 창의성을 향상시켜 재난 현장에서 적용하기 위해서는 이 분야의 연구가 필요하다. 이를 위해 본 연구는 창의성을 재난 관련 창의성과 일반 창의성으로 구분하고, 각 재난 관련 주체들과 관련된 연구의 방향을 제시하였다.

Rapid developments of IT technology has been creating new security threats. There have been more attacks to get patients' sensitive personal information, targeting medical institutions that are relatively insufficient to prevent and defend against such attacks. Although the government has required senior general hospitals to get the ISMS certification since 2016, such a requirement has been burdensome for small and medium-sized medical institutions. Therefore, this study was designed to draw measures to identify and improve the privacy status of the medical institution by dividing it into management, physical and cyber areas for small and medium-sized medical institutions. The results of this study showed that the government should provide financial support and managerial supervision for the improvement of personal information protection of small and medium-sized medical institutions. They also suggested that the government should also provide medical security specialists, continuous medical security education, disaster planning, reduction of medical information management regulations not suitable for small and medium sized institutions.

As interest in urban safety has increased since COVID-19, various institutions have developed and used indicators that evaluate the safety city model. Yongsan-gu was ranked No. 1 in 2021 by Social Safety Index evaluation and was selected as the safest city in Korea. However, the Itaewon disaster in Yongsan-gu in 2022 caused many casualties. The study of indicators for evaluating cities' safety was necessary. This study aims to examine domestic and foreign safe city models and review the differences between each model and the indicators used to evaluate safe cities. As a result of collecting 11 safe city models and analyzing each evaluation index, safe city models can be classified into program-based safe city models, such as the World Health Organization's International safe community and the UN Office for Disaster Risk Reduction's International Safe city. Considering the diversification of threats to safety, it is reasonable to comprehensively consider digital security, health safety, infrastructure safety, personal safety, environmental safety, traffic safety, fire safety, crime safety, life safety, suicide, and infectious diseases when evaluating safe cities as evaluation parameters.
