  • 현대의 화학공장 및 석유 가스산업 시설은 공정 및 설비가 더욱 복잡해지고 세분화됨으로써 산업현장에서는 다양한 잠재위험으로 인하여 화재, 폭발, 독성물질 누출 등의 중대 산업사고의 발생 가능성 및 사고결과의 피해가능 범위가 증가되고 있다. 이러한 위험요소를 줄이기 위하여 공정 내 안전장치를 설치하여 공정의 위험도를 줄여야 하지만, 공장 운전 효율성과 안전도는 서로 적절한 수준을 유지하지 않으면 잦은 검사와 확인으로 효율성을 저해할 수 있다. 그를 위하여 이번 연구에서 SIL(Safety Integrity Level)을 이용한 SIF(Safety Instrument Function)의 추가로 장치의 적절한 사양, 설계를 이루고 공정내의 잠재위험이 사고로 이어지는 것을 방지하여, 화학공장의 안전성을 향상시켰다.

  • Heavy metal(loid) contamination of rice is the main issue in abandoned metal mine area with regard to food safety. A field study was conducted in mine area to see if soil amendments treatment including calcium superphosphate, sulfur, steel slag and S-containing fertilizer could reduce As and/or Cd content in rice grain and increase the growth of rice. The As content in brown rice reduced to 60% compared to the control only in $7.0Mg\;ha^{-1}$ of steel slag treatment. Cd reduction in rice was thought to be not the effect of amendments but the result from the difference in growth and development of rice plant and this could be ascribed to low soil Cd availability to rice plant. Compared with control, increased rice yield of cultivar Hwanggeumnuri was 1.3~2.2 and $1.5Mg\;ha^{-1}$ in calcium super phosphate and S-containing fertilizer treatment, respectively and the trend was also observed in cultivar Ungwang. However, steel slag treatment reduced the Ungwang yield by $0.4{\sim}0.9Mg\;ha^{-1}$. Future work will be needed to establish the agricultural measure with which secure the safety and yield of rice simultaneously.

  • Objectives: The organizational culture of small-scale enterprises is influenced by a lack of awareness of industrial accidents and a business-oriented culture. Therefore, the purpose of this study is to establish a correlation between chemical awareness and worker safety, which is the reason why a company's safety environment is responsible for human factor accidents. Methods: The research model established the organizational culture, human relationships, organizational relationships, workplace culture, safety climate, and safety parameters, all of which affect the perception of chemical substances, then established safety rankings, communication, safety regulations, and safety support. Results: In order to derive the results of this study, the satisfaction level was mostly derived from the degree of engagement (+) depending on the number of years worked, in the hierarchical regression analysis. During work with chemicals, the number of years spent on the level of the service was determined by the influence of the chemical (-). Based on this company, the occurrence of chemical accidents caused by chemical materials was felt to be felt at the risk of causing the hazard to be felt, the absence of physical damage was excluded from the variables. The other variables detected in the variables were $62.8{\pm}24.4$. Conclusion: As a result, it is necessary to develop a statistical model for the verification of the hierarchical regression analysis, and the relationship between safety and awareness of the dangers of chemicals and biological agents requires periodic safety training. Job satisfaction was found to be higher if the level of awareness was sufficient.

  • For preventing the accidents generated from the chemical materials, thus far, MSDS (Material Safety Data Sheet) data have been made to notify how to use and manage the hazardous and chemical materials in safety. However, it is difficult for users who handle these materials to understand the MSDS data because they are only listed based on the alphabetical order, not based on the specific factors such as similarity of characteristics. It is limited in representing the types of chemical materials with respect to their characteristics. Thus, in this study, a lots of MSDS data are visualized based on relationships of the characteristics among the chemical materials for supporting safety managers. For this, we used the textmining algorithm which extracts text keywords contained in documents and the Self-Organizing Map (SOM) algorithm which visually addresses textual data information. In the case of Occupational Safety and Health Administration (OSHA) in the United States, the guide texts contained in MSDS documents, which include use information such as reactivity and potential risks of materials, are gathered as the target data. First, using the textmining algorithm, the information of chemicals is extracted from these guide texts. Next, the MSDS map is developed using SOM in terms of similarity of text information of chemical materials. The MSDS map is helpful for effectively classifying chemical materials by mapping prohibited and hazardous substances on the developed the SOM map. As a result, using the MSDS map, it is easy for safety managers to detect prohibited and hazardous substances with respect to the Industrial Safety and Health Act standards.

  • Objectives: A variety of industries handling hazardous chemicals emit odorous substances. Based on the emission characteristics of major odor substances from the results of hazardous chemical substance emissions, we will define basic data for improving the management methods of odorous substances. Methods: A survey of hazardous pollutant emissions for 2010-2016 was conducted through the Pollutant Release and Transfer Register homepage. Eight kinds of designated odor substances (ammonia, hydrogen sulfide, dimethyl disulfide, acetaldehyde, styrene, toluene, xylene, methyl ethyl ketone) provided the study subjects. The status of chemical accidents for the target substances was analyzed using the Chemistry Safety Clearing-house system. Results: From 2010 to 2016, it was found that more than 30% of businesses that emitted odorous substances accounted for more than 50% of the total emissions of the eight substances. Emissions of xylene, toluene, methyl ethyl ketone, and ammonia were found, in that order, and they made up more than 90% of the total emitted. By region, about 70% of odorous substances were emitted in the top-four regions: Gyeongsangnam-do Province, Ulsan, Gyeonggi-do Province, and Jeollanam-do Province. Conclusion: Recently, the amount of chemical emissions has been continuously increasing, including those that can cause odor. Odorous substances can be a serious risk to the lives of local residents. Systematic research is needed for the health protection of residents.

  • 지속가능성이란 사회적, 경제적, 환경적인 영향을 전반적으로 고려하며, 인간의 건강과 생활 증진을 내포하고, 환경자원의 보호와 경제적 번영을 의미한다. 지속가능성에 대한 심도 있는 이해는 이러한 환경적인 영향에 대한 고려뿐만 아니라 원료 및 자원채취, 이송, 생산 협력의 전반적인 순환을 다루어야 한다. 화학산업의 지속가능한 발전은 화학공정안전의 발전을 통한 상호보완적인 강화없이 이루어지기 어렵다. 이러한 관점에서 화학공정안전은 국제시장에서 경쟁력 강화의 기회라고도 할 수 있다. 화학공정안전의 변화하는 새로운 패러다임은 현존하는 시스템과 생산공정의 기본 디자인을 고려한 총체적 순환 전 과정으로부터 나온다. 이렇게 화학공정안전을 향상시키기 위해서는 관리 시스템을 포함한 정량적 위험성 평가 방법과 다양한 공정안전 데이터 및 지식베이스를 포함한 통합 스마트시스템의 개발이 필요하다. 본 논문에서는 화학산업안전의 전 과정 순환의 필요성에 대해 언급하였고, 이를 향상시키기 위한 공정안전 신기술에 대해 논의하였다. 변화하는 공정시스템공학에서 사고 없는 지속 가능한 산업의 발전을 위해서는 3 가지의 S, 즉 안전(Safety), 안정(Stability), 안보(Security)의 조합이 적절히 이루어져야 할 것이다.
