Managing security is essential for organizations doing business in a globally networked environment and for organizations that are at the same time seeking to achieve their missions and goals. However, numerous technical advancements do not always produce a more secure environment. All kinds of human factors can deeply affect the management of security in an organizational context. Therefore, security is not solely a technical problem; rather, the authors need to understand human factors, which need adequate attention to achieve an effective information security management system practice. This paper identifies direct and indirect human factors that have impact on information security. These factors were analyzed through the study of two security incidents of the UK's financial organizations using the SWOT (Strength, Weaknesses, Opportunities, and Threats) technique. The study's results show that human factors are the main causes for these security incidents. Factors such as training, awareness, and security culture influence organizational strength and opportunity relating to information security. People's irrational behavior and errors are the main weaknesses highlighted in security incidents, which pose threats such as poor reputation and high costs.

Increasing of renewable power plants has raised the need for intelligent energy management systems (EMSs). The aim of management system is to reduce energy absorbed from fossil sources. In this paper a layered behavioral based architecture named subsumption is employed for energy management in PV based power plant with storage devices and active load. In the proposed architecture components of the plant including SC, PV, battery, and the grid are organized in different layers. Each layer is implemented as a behavioral rule that can independently perceive and act in the environment. There is a hierarchy in the layers where lower layers have more priority and can inhibit higher layers. The layers use a simple protocol to communicate with management unit. Using this approach, a simple, fast, extensible, and fault tolerant EMS is achieved.

Non-destructive inspection (NDI) is one of the key elements in ensuring quality of engineering systems and their safe use. This inspection is a very complex task, during which the inspectors have to rely on their sensory, perceptual, cognitive, and motor skills. It requires high vigilance once it is often carried out on large components, over a long period of time, and in hostile environments and restriction of workplace. A successful NDI requires careful planning, choice of appropriate NDI methods and inspection procedures, as well as qualified and trained inspection personnel. A failure of NDI to detect critical defects in safety-related components of nuclear power plants, for instance, may lead to catastrophic consequences for workers, public and environment. Therefore, ensuring that NDI is reliable and capable of detecting all critical defects is of utmost importance. Despite increased use of automation in NDI, human inspectors, and thus human factors, still play an important role in NDI reliability. Human reliability is the probability of humans conducting specific tasks with satisfactory performance. Many techniques are suitable for modeling and analyzing human reliability in NDI of nuclear power plant components, such as FMEA (Failure Modes and Effects Analysis) and THERP (Technique for Human Error Rate Prediction). An example by using qualitative and quantitative assessesments with these two techniques to improve typical NDI of pipe segments of a core cooling system of a nuclear power plant, through acting on human factors issues, is presented.

Nowadays, modern power converters installed in renewable power plants can provide flexible electromechanical characteristics that rely on the developed control technologies such as Synchronous Power Controller (SPC). Since high renewable penetrated power grids result in a low-inertia system, this electromechanical characteristic provides support to the dynamic stability of active power and frequency in the power generation area. This goal can be achieved through the proper tuning of virtual electromechanical parameters that are embedded in the control layers of power converters. In this paper, a novel mathematical pattern and strategy have been proposed to adjust dynamic parameters in Renewable Static Synchronous Generators controlled by SPC (RSSG-SPC). A detailed dynamic modeling was obtained for a feasible design of virtual damping coefficient and virtual moment of inertia in the electrometrical control layer of RSSG-SPC’s power converters. Mathematical solutions, modal analysis outcomes, time-domain simulation results, and real-time validations of the test in IEEE-14B benchmark confirm that the proposed method is an effective procedure for the dynamic design of RSSG-SPC to provide these dynamic stability supports in grid connection.
