  • 고용노동부 공문(최근 건설업 사망사고 발생 현황 안내 및 안전관리 철저 당부, 2022.4.4.)에 따르면, 중대재해처벌법 시행(2022.1.27.) 이후 2022.3.31.까지 공사금액 50억원 이상 건설공사에서 17건의 사망사고가 발생하여 18명이 사망했다. 공사규모로 보면 50억~120억원 7건, 120억~800억원 5건, 800억원이상 5건이 발생했다. 사망사고 발생원인은 떨어짐 9건(50%), 맞음 5건(28%), 무너짐 2건(11%), 끼임 1건(5%), 익사 1건(5%)으로 조사됐다. 사망사고의 대부분을 차지하는 떨어짐과 맞음으로 인한 사망사고를 줄이기 위해서는 안전시설물을 강화할 필요가 있으며, 추락방지망·개구부·안전난간이 완벽하게 설치되면 대부분의 떨어짐과 맞음 사고는 예방 할 수 있다. 따라서 본 고에서는 소규모 공동주택인 도시형생활주택신축현장의 떨어짐과 맞음 사고를 예방하기 위해서 안전시설물 개선을 통한 특허기술 개발과 활용 사례를 제시하고자 한다.

  • Even at this point in the era of digital transformation, we are still facing many problems in the safety sector that cannot prevent the occurrence or spread of human casualties. When you are in an unexpected emergency, it is often difficult to respond only with human physical ability. Human casualties continue to occur at construction sites, manufacturing plants, and multi-use facilities used by many people in everyday life. If you encounter a situation where normal judgment is impossible in the event of an emergency at a life site where there are still many safety blind spots, it is difficult to cope with the existing manual guidance method. New variable guidance technology, which combines artificial intelligence and digital twin, can make it possible to prevent casualties by processing large amounts of data needed to derive appropriate countermeasures in real time beyond identifying what safety accidents occurred in unexpected crisis situations. When a simple control method that divides and monitors several CCTVs is digitally converted and combined with artificial intelligence and 3D digital twin control technology, intelligence augmentation (IA) effect can be achieved that strengthens the safety decision-making ability required in real time. With the enforcement of the Serious Disaster Enterprise Punishment Act, the importance of distributing a smart location guidance system that urgently solves the decision-making delay that occurs in safety accidents at various industrial sites and strengthens the real-time decision-making ability of field workers and managers is highlighted. The smart location guidance system that combines artificial intelligence and digital twin consists of AIoT HW equipment, wireless communication NW equipment, and intelligent SW platform. The intelligent SW platform consists of Builder that supports digital twin modeling, Watch that meets real-time control based on synchronization between real objects and digital twin models, and Simulator that supports the development and verification of various safety management scenarios using intelligent agents. The smart location guidance system provides on-site monitoring using IoT equipment, CCTV-linked intelligent image analysis, intelligent operating procedures that support workflow modeling to immediately reflect the needs of the site, situational location guidance, and digital twin virtual fencing access control technology. This paper examines the limitations of traditional fixed passive guidance methods, analyzes global technology development trends to overcome them, identifies the digital transformation properties required to switch to intelligent variable smart location guidance methods, explains the characteristics and components of AI-based public facility smart fire safety integrated system (ISFS).

  • Financial firms, especially large scaled firms such as KB bank, NH bank, Samsung Card, Hana SK Card, Hyundai Capital, Shinhan Card, etc. should be securely dealing with the personal financial information. Indeed, people have tended to believe that those big financial companies are relatively safer in terms of information security than typical small and medium sized firms in other industries. However, the recent incidents of personal information privacy invasion showed that this may not be true. Financial firms have increased the investment of information protection and security, and they are trying to prevent the information privacy invasion accidents by doing all the necessary efforts. This paper studies how effectively a financial firm will be able to avoid personal financial information privacy invasion that may be deliberately caused by internal staffs. Although there are several literatures relating to information security, to our knowledge, this is the first study to focus on the behavior of internal staffs. The big financial firms are doing variety of information security activities to protect personal information. This study is to confirm what types of such activities actually work well. The primary research model of this paper is based on Theory of Planned Behavior (TPB) that describes the rational choice of human behavior. Also, a variety of activities to protect the personal information of financial firms, especially credit card companies with the most customer information, were modeled by the four-step process Security Action Cycle (SAC) that Straub and Welke (1998) claimed. Through this proposed conceptual research model, we study whether information security activities of each step could suppress personal information abuse. Also, by measuring the morality of internal staffs, we checked whether the act of information privacy invasion caused by internal staff is in fact a serious criminal behavior or just a kind of unethical behavior. In addition, we also checked whether there was the cognition difference of the moral level between internal staffs and the customers. Research subjects were customer call center operators in one of the big credit card company. We have used multiple regression analysis. Our results showed that the punishment of the remedy activities, among the firm's information security activities, had the most obvious effects of preventing the information abuse (or privacy invasion) by internal staff. Somewhat effective tools were the prevention activities that limited the physical accessibility of non-authorities to the system of customers' personal information database. Some examples of the prevention activities are to make the procedure of access rights complex and to enhance security instrument. We also found that 'the unnecessary information searches out of work' as the behavior of information abuse occurred frequently by internal staffs. They perceived these behaviors somewhat minor criminal or just unethical action rather than a serious criminal behavior. Also, there existed the big cognition difference of the moral level between internal staffs and the public (customers). Based on the findings of our research, we should expect that this paper help practically to prevent privacy invasion and to protect personal information properly by raising the effectiveness of information security activities of finance firms. Also, we expect that our suggestions can be utilized to effectively improve personnel management and to cope with internal security threats in the overall information security management system.

  • 최근 건설현장은 인건비 상승, 중대재해처벌법 등으로 인한 건설 현장 여건의 변화로 탈현장 여건으로 프리캐스트 부재 생산에 대한 관심이 증대되고 있다. 특히, 프리캐스트 프리스트레스트 중공슬래브는 단면 내 중공형상을 두어, 중량감소 및 강연선을 통한 처짐 제어 등으로 구조성능은 확보하고 있으나, 현재 내화 성능 개선에 대한 미비한 연구 뿐만 아니라, 기업들의 근거 없는 당연내화구조 기준을 적용함에 내화성능 확보에 대한 시급성이 대두되고 있다. 이 연구에서는 기존 중공 슬래브와 비교하여 동등이상 구조성능, 경제성을 갖기 위하여 슬래브단면 내 중공 형상 최적화를 통해 단면 내 콘크리트 충진률 감소 및 상하부 플랜지 형상 개선으로 내화단면을 개발하였다. 이를 적용한 PC 중공 슬래브에 대하여 단면두께를 변수로 하여 2시간 내화시험을 진행하여, 실험결과 내화 성능(하중지지력, 차열성, 차염성)을 확보 하였다. 실험 결과 기반으로, 수치해석 시뮬레이션을 통해 내화모델링을 정립하여, 추후 단면형상 변경에 따라 내화 해석 예측이 가능한 것으로 판단된다.
