Classification of explosion hazard areas is very important in terms of cost and safety in the workplace handling flammable materials. This is because the radius of the hazardous area determines whether or not the explosion-proof equipment is installed in the electrical machinery and apparatus. From November 6, 2017, KS C IEC-60079-10-1: 2015 will be issued and applied as a new standard. It is important to understand and apply the difference between the existing standard and the new standard. Leakage coefficients and compression factors were added to the leakage calculation formula, and the formula of evaporation pool leakage, application of leakage ball size, and shape of explosion hazard area were applied. The range of the safety factor K has also been changed. Also, in the radius of the hazardous area, the existing standard applies the number of ventilation to the virtual volume, but the revised standard is calculated by using the leakage characteristic value. In this study, we investigated the differences from existing standards in terms of ventilation and dilution and examined the effect on the radius of the hazard area. Comparisons and analyzes were carried out by applying revised standards to workplaces where existing explosion hazard locations were selected. The results showed that even if the ventilation and dilution were successful, the risk radius was not substantially affected.

In this study, the UAV (Unmammed Aerial Vehicle) was applied for the photogrammetry of the construction site and the safety management of steel pipe scaffold. The research site is a temporary facility for building reinforcement on Samcheok Campus of Kangwon National University. The installation condition of the steel pipe scaffold was investigated, and the pillar distance, the beam distance and the wale distance were surveyed. As a result, it was found that the beam distance of the scaffold in the longitudinal direction was in good agreement with the standard, but the pillar distance and the wale distance were found to be less than the standard. Three-dimensional data can be used in drone shooting to enable three-dimensional measurement, so that it is possible to measure facilities hidden or located inside other facilities. Through the drone shooting, the condition of the site can be quickly recorded and the surveying can be carried out without interfering with the work of the field personnel. Although the installation of the temporary structure must be strictly observed to ensure the safety of the workers, it is found that the installation standards are still neglected in the field. In order to prevent this practice, it was thought that the legal system should be supplemented so that it could be checked periodically by using UAV in the field process management.

It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.

Purpose: In order to enhance safety, the Korea Navy is making efforts to introduce a safety and health management system and to develop a risk assessment system, while safety accidents keeps occurring. A development plan was proposed through an inspection of the Safety Management System(SMS). Method: To diagnose the Korea Navy's safety management system, changes in the safety environment, documentation system, and safety and health management system operation were reviewed, points to be improved were found, and improvement directions were derived. Result: There is a need for an SMS standard that can present the Korea Navy's safety policy and safety management direction, and a safety program that provides guidelines for implementing it in a standardized manner. To this end, we were able to confirm the feasibility of linking the requirements of the US Navy's SMS and the international standard ISO 45001 standard together with the Korea Navy's safety management system. Conclusion: The Korea Navy's safety management system needs to clearly present safety policies and standards, and have public confidence and effectiveness in safety work through a standard program that can implement them, and for this, the development of a Navy SMS is necessary.

Recently, in circumstantial situation it is recommended positively to utilize of EIFS(Exterior Insulating and Finishing System) as energy policy for economizing energy. But internal EPS insulators of EIFS are exterior panel of high fire risk, because of constituting of flammable materials to be fragile in fire. In this study, fire risk is assessed by experiment Con Calorimeter test and SBI(Single Burning Item) test. As the result of experiment, Con Calorimeter tests do not reach to capability standard of internal incombustible grade, and are assessed as low grade in SBI incombustible grade. Because EIPS is exterior material in buildings with high fire risk in spite of good efficiency, it is required rapidly to take measures to meet situation through various studies(for instance, adjusting law regulation, etc.) in the future.

중대재해처벌법(이하 "동법" 병기) 시행 전후로 동법에 대응하기 위한 정부 지원과 학계 연구는 많이 진행되어 왔으나, 대부분은 사전 예방에 치중되어 재해 발생 이후 기업 운영상의 리스크 관리나 피해경감 등을 위한 연구가 부족하였다. 중대재해를 줄이기 위해서는 사전 예방이 우선이지만 재발방지 및 추가 피해 최소화 노력도 뒤따라야 한다. 따라서, 본 논문에서는 재난 및 업무중단성 사고에 대하여 예방, 대비, 대응 및 복구활동에 필요한 문서화된 관리체계를 규정하고 있는 재해경감활동관리체계(이하 "동 체계" 병기)를 활용하여 중대재해처벌법을 준수할 수 있는 방안을 연구하였다.
