In the Public Notice No. 2019-15 of the Ministry of Employment and Labor, the safety net and regulations on them have been deleted. The performance criterion of the debris net, which also functions as a horizontal safety net in the regulations on the criteria of occupational safety and health, is unclear. When installing a debris net that also functions as a horizontal safety net, a net that meets the performance criteria of KS F 8082 must be installed in accordance with KOSHA C-31-2017. The Korean Standard Specification for Construction Works, which specifies debris net and horizontal safety net, should be revised as soon as possible.

우리나라도 이제 자율안전감시활동 참여가 우수한 협회에는 'Safety Guard' 마크를 부여하고 포상하는 제도를 계획했다. 이 제도를 제품 자체에 확대 적용해 임의표준을 더욱 활성화하는 것이 요구된다.

Thorough preparations and investigations must be done in order to prevent the hazards which will happen when workers work on the roof of the rolling stocks. Some industrial disasters can be prevented by solving the risks involved in the working of the work processes. Falling accidents tend to happen from the roof of the trains when workers work in the high position. So through the analysis of the 4M( Man. Machine, Media, Management), this paper analyzed the risk factors among the roof works and all problems of the maintenance. Also this paper suggests new devices or new methods to prevent falling disasters and to relieve the mental senses of uneasiness.

The statistics of committing suicide in S. Korea is ranked in top with serious attempts of falling among OECD countries since 2003. The rates is slightly dropped by 5 percent point, nevertheless the falling is still high for the age of over 10 years old and this matter must be solved. Most of the case of suicides are the falling based on a trend view of falling which is serious matter and cannot be solved easily for both domestic and foreign countries. For example, the steel net of falling prevent was installed in the Golden Gate Bridge costed by 200 million-dollar. In New Zealand, the steel net of falling prevention had been removed and re-installed beccause of the high suicide rates. Canada and Australia also surrounded the bridge with steel fences to prevent suicide without consideration of the beauty of bridge. Therefore, this paper suggested a comparison study on both falling prevention systems in all countries and patent technologies. Also, it covers the blocking skills of approach in both security and limited area. This paper suggested the technical Rollinder system equipped with the mechanical apprentice to prevent effectively the falling sucides and wall passing. Before the installation of Rollinder System by 2016, there were 33 person who tried to fall in the river in Machang Bridge. However, the number of the committing suicides were dramatically reduced to zero after the installation of the system.

Recently, big data is rapidly emerging as a core technology in the 4th industrial revolution. Further, the utilization and the demand of drones are continuously increasing with the development of the 4th industrial revolution. However, as the drones usage increases, the risk of drones falling increases. Drones always have a risk of being able to fall easily even with small problems due to its simple structure. In this paper, in order to predict the risk of drone fall and to prevent the fall, ESC (Electronic Speed Control) is attached integrally with the drone's driving motor and the acceleration sensor is stored to collect the vibration data in real time. By processing and monitoring the data in real time and analyzing the data through big data obtained in such a situation using a Fast Fourier Transform (FFT) algorithm, we proposed a prediction system that minimizes the risk of drone fall by analyzing big data collected from drones.

피로에 있어서 해결되지 않은 문제는 현재도 허다하여 많은 연구가 필요하나, 현재까지의 지식 으로도 크나 큰 피로파괴사고는 충분히 방지할 수 있다고 저자는 생각하고 있다. 본고의 파손 해소예로부터도 어느 정도 추측이 가능하듯이 현재의 파괴사고의 대부분은 인위적인 것이다. 인위적인 파괴사고를 방지하는 방법의 하나는 합리적인 설계 및 보수, 관리시스템을 확립하는 것일 것이다. 당해기술이 현재도 미흡한 국내에서는 그 필요성이 더욱 절실히 느껴져, 본고에서 소개한 건전성 평가절차도 그러한 맥락에서 이루어지고 있다.

Every year on a construction site safety scale of the crash of an accident, but the large and small, accounting for more than half. In Construction Field wearing safety belts for their safety, but the impact of fracture, including the risk of injury occurs. Accordingly, the death as well as by the crash, injuries that can reduce the size of the invention was driven by safety belts.

Most frequently happening accident in construction working sites was fall in high and dangerous position. Most of fall accidents resulted in serious injury or death of workers. In this research was analysed recent safety accidents for three years from 2010' to 2012 and was developed the safety equipment to be able to efficiently prevent and reduce fall accidents. This new safety equipment can be easily fixed to the reinforcing steel or steel girder etc by the fixing hook of life saving line and is comfortablely portable because of its light weight. The questionnaire study of the developed equipment was performed to investigate the problem in the view point of using in real sites. The result shows that the new fixing fook can reduce fall accidents and satisfy construction workers.

Flying net should be installed on every 3 or 4 construction floor from 8m above ground according to the rule. In the apartment housing construction, flying net installation work has been recognized the most dangerous work among the whole works because a small mistake of labors might make their death accident. Sub-contractors specialized in flying net have been developing various flying net types. However, most works of installing flying net as working with the developed system are performed outside the apartment housing, so that the risk of fall in works of installing supports and unfolding net is still high. Furthermore, as using the previously developed flying net labors might bump into the frame or the wire rope for supporting so that it makes secondary accidents. The objective of this research is to produce the proto-type of anti-collision flying net system based on the result of problem analysis on the installation and detachment process and suggest the improved anti-collision flying net system, which is able to improve safety and field applicability by conducting field experiment and analyzing performance.
