It is a challenge to prevent an occupational accident in any industrial activities. The aim of this study is to improve the safety and reduce the risk of occupational accidents at shipyard through developing a risk assessment. This paper describes the concept and methodology of risk assessment for occupational safety and its application. The methodology introduces an effective and useful assessment procedure to construct the database based on the past occupational accidents occurred at shipyards. Quantitative methodology is developed to understand the unsafe working conditions and environment at the shipyard by the convenient handheld to collect the data with Information Technology. Some examples of effective hazard countermeasures are suggested and a feasibility study is conducted to improve a walking environment at shipyards.

It is a challenge to prevent occupational accidents in any industrial activities. The aim of this study is to improve safety and reduce the risk of occupational accidents at shipyards by developing a risk assessment methodology using work observation technique. This article describes a concept and methodology of risk assessment for occupational safety and its application. It introduces an effective and useful assessment procedure designed from a database based on the past cases of occupational accidents at shipyards. A quantitative method is developed to understand unsafe working conditions and environment at shipyards. A mobile device is used to collect the work observation data at the shipyard, and some examples of effective hazard measures are suggested. Based on the methodology, a feasibility study was conducted to improve walking safety at a numerical control (NC) cutting process of a shipyard in Japan.

The paper presents a risk assessment methodology for operational limit states of submarine outfall projects that considers: the environmental legislative framework, the climate agents acting on the coastline and prediction of the plume long-term behaviour near the coastline. The probability of operational failure or stoppage is assessed enabling decision on project design alternatives.

Introduction: Identifying occupational hazards and managing occupational safety and health risks has been the most important mission and responsibility of the health and safety management system in organizations and adopting coded plans to achieve this is the key to continuously improving this system and promoting it. The aim of the present study was to determine the optimal risk assessment methodology in development projects. Materials and Methods: This was a descriptive-analytic research In this research, using previous research studies and collecting expert opinions, the most important criteria for selecting a specific risk assessment methodology, and then using one of the three most-used techniques is an important activity in the steel making industry and risk assessment. Then, the decision matrix is based on the strengths and weaknesses of the models. The prioritization of these three methods is done using the hierarchical analysis decision method. Results: In this paper, five key factors, the degree of application in identifying hazards, usability in different stages of risk assessment, reliability, ease of use, and training needs and costs, are identified as the most important criteria for choosing a risk assessment technique and the FMEA method was considered as the best  Risk Assessment Method. Conclusion: FMEA methodhas been introduced with regard to its capabilities as an optimal risk assessment method for contruction projects.

Keyhole neurosurgery implies reaching a target area inside the brain through an entry point specified by the neurosurgeon. In order to avoid complications, a risk assessment procedure must be done to establish the minimum risk trajectory from the entry point to the target area. The neurosurgeon establishes the risk values for the brain structure according to the type of intervention. The preset brain structure risk value is used to assess the risk value for each voxel of the brain. This paper proposes an improved risk assessment methodology based on the sum of N maximum risk values for each voxel. Then, risk assessment for a trajectory is done by adding the risk of all voxels that are part of the path. The safest trajectory is defined as the trajectory with the lower risk. Our proposed search trajectory methodology includes a Genetic Algorithm (GA) for finding the safest trajectories. The use of a GA drastically reduces the number of trajectories to analyze, speeding up the planning procedure. The achieved results were qualified by expert neurosurgeons as satisfactory. Our proposed method allows neurosurgeons to calibrate the surgical planning system by allowing them to establish the risk brain structure and the risk value for each structure.

Abstract As counterfeiting techniques and processes grow in sophistication, the methods needed to detect these parts must keep pace. This has the unfortunate effect of raising the costs associated with managing this risk. In order to ensure that the resources devoted to counterfeit detection are commensurate with the potential effects and likelihood of counterfeit part usage in a particular application, a risk based methodology has been adopted for testing of electrical, electronic, and electromechanical (EEE) parts by the SAE AS6171 set of standards. This paper provides an overview of the risk assessment methodology employed within AS6171 to determine the testing that should be utilized to manage the risk associated with the use of a part. A scenario is constructed as a case study to illustrate how multiple solutions exist to address the risk for a particular situation, and the choice of any specific test plan can be made on the basis of practical considerations, such as cost, time, or the availability of particular test equipment.

Often, the employers allocate funds for occupational safety on the residual principle without considering the real needs in creating safe working conditions for the employees. This is especially topical for the small and medium-sized enterprises, whose budget, as a rule, does not allow to allocate sufficient funds for occupational safety. The substantiation is given concerning the need to improve modern systems for assessing the state of working conditions by integrating the missing elements, which are part of similar systems, selected during the analysis of domestic and foreign studies. In the critical review of foreign publications in the field of assessing the state of working conditions, the tools developed over the past 15 years are considered. The lines of business are selected related to the improvement of system for assessing the state of working conditions at the small and medium-sized Russian enterprises. To determine the most optimal methods, an algorithm is proposed for selecting the tools to assess the state of working conditions based on determining the efficiency parameter corresponding to each tool. Modern Russian methods are assessed in a similar way. As a result of the study, two tools for assessing the state of working conditions that are most optimal for small and medium-sized enterprises are selected. The analysis showed that the first selected method allows to assess the state of the personnel working conditions, i.e., gives a subjective assessment. The second method serves for an objective study of the estimated parameters, as well as for assessing the level of occupational hazard. Combined use of both tools can become the basis for the formation of a methodology for a comprehensive assessment of the state of working conditions at the small and medium-sized enterprises.
