The law(construction standard specification, construction, standard-work regulation, Industry safety standard related regulation) related to the installation of scaffolding being used commonly on the construction site is regulated that the gap of ledger is within 1.5m and first ledger is within 2m. The gap of ledger here is essential for the stability of scaffolding structure. But it is determined that it is possible for the gap of ledger is applied by explaining safety handrail as ledger, because of the fact that in current, on the construction site, safety handrail is installed with the material of scaffolding ledger as a steel tube pipe. On this study, it is aimed to guarantee the safety by analyzing the ledger of scaffolding practically and prevent the accident of manager and laborer through the actualization.

Depending on the growth of the construction industry, size of construction sites are becoming enlarged, and construction work is becoming diversified as well. However, this increases risks of safety accidents. In order to alleviate this problem, some large construction companies have implemented a Safety Patrol Management System (SPMS) in order to reduce accidents on construction sites. Aimed at the construction sites where SPMS has been applied, the purpose of this research is to calculate the proper number of SPMS safety mangers by comparing and contrasting the number of safety managers per person for each site with different sizes and the converted accident ratio. In addition, we also aim to calculate the adequate amount of SPMS safety management costs compared to the total amount of construction expenses required once SPMS is introduced.

In recent years, environments of business are changing due to epoch-making development of information technology and the advent of digital economy ages. It is an active confrontation as to the environments for information. Unlike the large scale enterprises in those days, hower, many small & medium enterprises especially the enterprises which are engaged in the manufacturing industry-aren't participate in information's rank due to the lack of funds, manpower, insufficient management environments, and manager or staff's lack of cognition as to information. So, this paper make a base of establishment for ISP through the establishment of ERP that is used to management activity for small & medium manufacturing enterprises. A way for small & medium enterprises' ERP construction is SMERP S/W for the small & medium enterprises' ERP package which is offered by the Korea chamber of commerce & industry. And, that is applied to the real management environment.

The purpose of this paper is to verify if safety managers must bear stress from additional tasks whenmanaging smart safety technology applications on construction sites. We conducted a survey of 133 safety managers who had experienced managing both safety management and smart safety technology applications at construction sites, and used the SPSS Statistics 25 and AMOS 22 programs to analyze the survey's logicality and the data that we collected. We found that the work burden caused by assuming additional tasks to manage smart safety technology applications affected the stress that safety managers experience when working at construction sites. The stress caused by an increased work burden led construction site safety managers to feel dissatisfied with their jobs. This finding indicates that both on the original job and on additional tasks are entirely mediated. Based on this finding, I suggest that the South Korean government should establish smart safety technology applications, thus reducing the work burden and increasing the job satisfaction for construction site safety managers.

Domestic construction industry has considerable level of construction performance and technology thanks to the economic development and as the result of performing diverse oversea construction project. However, construction disasters have been steadily increasing, and do severe disasters at faster pace. Most of such disasters happen at small and small medium-sized construction fields, which contract size is less than 10 billion won. small and medium-sized construction fields are not obliged to designate a safety manager, and have limitations in engaging self-regulating disaster prevention activities due to reduced budget for safety facilities. For the small and medium-sized construction sites with less than 10 billion won, the Ministry of Labor has been carrying out mobile inspections of construction safety. However, the effect so far is insignificant and an improvement plan is required. Therefore, in the present thesis, we derive problems appearing in the current construction safety mobile inspection system, investigate and study systems in foreign countries, and suggest an efficient and effective plan to operate safety technology inspections. First of all, we establish a standard to select sites to be inspected that are high in construction risk and disaster occurrence probability In addition, we suggest a plan to take administrative and judiciary measures based on the total score for disaster factors considering the disaster occurrence probability and the illegal practices. Furthermore, a scheme to maximize the effect of disaster prevention is sought by building an organic cooperative system between the Ministry of Labor, Korea Occupational Safety ＆ Health Agency and other organizations specialized in instruction of construction disaster prevention. Finally, we induce a research conclusion that leads to self-regulating safety management through checking and instructing systematic management on mobile inspections.

Due to the dense and complicated working environment, the construction industry is susceptible to many accidents. Worker's fall is a severe problem at the construction site, including falling into holes or openings because of the inadequate coverings as per the safety rules. During the construction or demolition of a building, openings and holes are formed in the floors and roofs. Many workers neglect to cover openings for ease of work while being aware of the risks of holes, openings, and gaps at heights. However, there are safety rules for worker safety; the holes and openings must be covered to prevent falls. The safety inspector typically examines it by visiting the construction site, which is time-consuming and requires safety manager efforts. Therefore, this study presented a worker-driven approach (the worker is involved in the reporting process) to facilitate safety managers by developing integrated computer vision and inertia sensors-based mobile applications to identify openings. The TensorFlow framework is used to design Convolutional Neural Network (CNN); the designed CNN is trained on a custom dataset for binary class openings and covered and deployed on an android smartphone. When an application captures an image, the device also extracts the accelerometer values to determine the inclination in parallel with the classification task of the device to predict the final output as floor (openings/ covered), wall (openings/covered), and roof (openings / covered). The proposed worker-driven approach will be extended with other case scenarios at the construction site.

지난 20년간 건설산업의 재해는 절대적인 수치에서는 감소했다. 그러나 중·소규모 건설현장에서의 발생한 재해는 건설산업 전체의 약 80% 이상을 차지하고 있으며 지속적인 증가세를 나타내고 있다. 건설산업에서의 재해 저감을 위해 고용노동부는 건설업에서 상대적으로 막강한 권한을 보유한 발주자에게 안전에 대한 책임을 의무화하여 선제적으로 재해 예방을 하도록 단계별 안전보건대장 작성 제도를 법제화하였다. 제도의 활성화를 위해서는 많은 연구들이 필요하지만, 지금까지 안전관리계획, 유해·위험방지계획 등과 관련한 연구는 많았지만 안전보건대장과 관련한 연구는 없었다. 따라서 본 연구에서는 중·소규모 건설현장의 재해 저감을 위한 방안으로 발주자의 안전보건관리 절차와 연계한 개선된 안전관리 절차를 제시하였다. 공사단계의 안전관리는 공종별 교육, 안점점검을 하도록 하여 현장상황과 일치하는 관리가 되도록 하였으며, 모든 정보는 전통적인 방식의 서류형태의 문서를 대체하여 데이터 기반의 절차가 되도록 하여 관리자의 업무부담을 낮추었다. 개념적인 절차의 제시로 향후 추가 연구가 필요하지만, 중·소규모 건설현장의 안전관리 지원 정보시스템 개발을 위한 기초자료로 활용될 것으로 기대한다.

The purpose of this study is to analyze safety and health managers' perceptual maps on the effective educational contents and its methods of workplace safety and health education. Self-administered survey was successfully conducted to 582 workers who were 339 in manufacturing, 68 in construction, and 175 in service & others by industry classification. Survey sites were recruited based on business size, incidence of occupational accident, and compliance of workplace safety and health education regulation. Questionnaire included personal factors, workplace factors, and needs of safety and health education at work. Male workers were 85.3% and more than 50% were in their 30s and had university education. Overall needs of educational contents and its methods were greater in manufacturing and services than construction. Two dimensional properties of effective educational contents perceived were 'knowledge structure' which divided to safety and health, and 'behavior outcomes' which divided to indirect and direct. Two dimensional properties of educational methods were 'class activity' which divided to experience-based and verbal-based and 'class participation' which divided to passive and active. Effective educational contents and its methods perceived by safety and health managers commonly included the characteristics of direct, case-based, and participation.
