  • worker-centered safety management for hazardous areas in the plant is required. The causes of gas accidents in the past five years are closely related to the behavior of the operator, such as careless handling of the user, careless handling of the suppliers, and intentional, as well as equipment failure and accident of thought. In order to prevent such accidents, real-time monitoring of hazardous areas in the plant is required. However, when installing a camera in a work space for real-time monitoring, problems such as human rights abuse occur. In order to prevent this, an infrared camera with low resolution with low exposure of the operator is used. In real-time monitoring, image analysis is performed using CNN algorithm, not human, to prevent human rights violation.

  • 가스를 사용하는 산업 영역이 지속적으로 확장됨에 따라, 가스작업의 안전 관리 문제가 중요하게 대두되고 있다. 이는 특히 최근 발전 중인 사물네트워크(이하 IoT)를 활용하여 작업안전관리를 보다 용이하게 이루어가는 방향으로 연구되고 있다. 본 논문에서는 국내외에서 개발 중인 가스 시설 안전을 위한 IoT 시스템과 작업자를 효과적으로 연동시킬 수 있는 모바일 앱의 설계 방안을 모색하기 위해 우선적으로 작업자의 사용 용이성을 확보하기 위한 설계 방향을 설정하고, 이를 기준으로 석유화학산업에서 이루어지는 작업을 분류하여 배치하였다.

  • Currently, most of the industrial areas like chemistry, manufacturing, shipbuilding, and steel, perform the work related to gas, and the staffs who are in charge of this work have a risk of suffocation without cognizing incidents like gas leak. For example, when the nitrogen gas leaked in 2015 at Paju, two people were killed and four people were injured. In 2018 at Pohang, four workers were suffocated to death from nitrogen gas. In order to solve this problem, this study realized the system in which workers could immediately cognize the gas leak and also deliver the situation to the staff in charge of safety at the same time, by installing the IoT device composed of gas sensor and communication module on the safety helmet that should be worn by field workers. This study is expected to be able to reduce the casualties caused by gas leak in industrial sites.

  • This study covers the results obtained after three years of development work of real - time gas safety monitoring app. In order to reduce the risk of accidents in the gas workplace, it is essential to provide information so that operators can recognize the location of dangerous substances, dangerous facilities, safety procedures, and the temperature and humidity of the workplace. Therefore, this study was conducted to develop a monitoring app that allows the main system to efficiently receive the information in the field where the information is continuously updated. As a result of quantitative and qualitative research and analysis on app scenarios based on the research done in the past and web screen of the main system, it was modified and improved in terms of ease of use, readability, and intuitiveness. Especially, we made many improvements at low depth, which is a sub-area of ease of use. As a result of conducting a user satisfaction survey on the finally derived app scenarios, the average score of 98.5 was obtained in terms of functionality, convenience and readability.

  • The issue about the safety management of gas related work has been studied toward a direction to utilize IoT system recently. For this purpose, the matters of user's demand has been deduced through the literature survey, field survey, and professional consultation, by studying the characteristics of worker, work, and work site. In summary, these are the demands for mobile App, 1)a clear arrangement of contents, 2)a design with high readability, 3)a design with low death, 4) securing of user's accessibility, 5)an effective information transmission plan in the work section where it is impossible to operate the mobile device, 6)an activation of alarm function at the section of high working error, 7)a fast two-way transmission and receipt of safety inspection matter needed at work, 8)a selection of images and contents that can guide the situation to the worker in case of accident, 9)an alarm function for the degree of danger in an area of worker's location. Based on these, a basic design of safety application for gas related work has been proposed, that can secure the user accessibility.

  • 안전, 또 안전!은 아무리 강조해도 지나치지 않다. 한때 우리나라는 '안전불감증'이라 해도 과언이 아닐만큼 안전에 대한 의식이 저조해서 사고가 많았다. 이에 따라 각 건설현장에서는 안전에 대한 교육을 철저히 시키고 행동강령 주지 등 많은 노력을 기울여 왔다. 특히 가스와 관련한 사고는 대형사고로 번질 가능성이 높기 때문에 작업 시 더욱 주의를 필요로 한다. 본지는 가스시공 시의 일반적인 안전수칙과 탱크, 용기, 기계실, 고소작업, 용접작업 천공 분기작업, 도시가스 공급시설물 작업 시의 안전수칙에 대하여 게재한다.

  • 반도체의 생산공정은 생산제품의 특성상 많은 종류의 위험물과 가스를 이용하는 것이 보통이지만, 자동화가 이루어진 대부분의 작업공정과는 달리, 작업자에 의해 직접 이루어지는 것이 보통이다. 이때 작업자의 사소한 실수나 과오로 인해 일단 누출등의 사고가 발생하면, 취급물질 자체의 위험성으로 인해 인명 피해, 화재 및 폭발 둥의 2차 대형재해를 초래할 수 있기 때문에, 반도체공장의 어느 누구도 그 위험성에 대해 과소평가하지 않는 것이 현실이다. (중략)

  • 밀폐된 공간으로 이루어진 작업장은 여러 가지 유해가스가 많이 발생된다. 이로 인해 환기가 불충분한 작업공간에서는 산소결핍 및 유해가스로 인한 건강장해와 인화성 물질에 의한 화재, 폭발 등의 위험이 존재한다. 따라서 유해가스 정보를 작업장 내의 센서를 통해서 실시간으로 모니터링하고, 위험으로부터 작업자의 안전을 보장할 수 있는 모니터링 시스템이 필요하다. 특히, 상황에 맞는 의사결정이 가능하도록 하기 위해 상황인식 시스템의 도입이 필요하다. 이 논문에서는 작업장의 유해가스 정보를 모니터링하기 위한 추론 규칙을 JESS를 기반으로 설계한다.

  • Analysis of risky behavior factors for workers in the manufacturing industry enables effective human error prevention and systemization of an efficient safety management system. This study examines the relationship between the effects of workers' work psychology, work environment, and work deviation factors on risky behavior intentions and the effects of such risky behavior intentions on risky behaviors. Among the small and medium-sized manufacturing industries, the analysis was focused on a survey of 80 workers in the manufacturing and processing industry. Looking at the results, it was found that work psychology and work deviation had an effect on the intention of risky behavior, but the work environment factors corresponding to job satisfaction and workload did not affect the intention of risky behavior. The relationship with colleagues, the degree of satisfaction or dissatisfaction with the job, the degree of importance of the job that the worker feels, and the tightness of time to digest a large amount of work do not affect intentionally inducing dangerous work, but they do affect risky behavior. In the absence of intention, the work environment factor was found to accompany dangerous behavior.
