“…In Figure 9, it is demonstrated that the implementation of security policies based on this proposal had a positive impact. According to the author [24], in order to set security policies in the IT infrastructure it is recommended to do a report before and after its implementation [25], to do an accurate comparison and know if the changes did work or need to be reformulated back to the initial stage. Regarding this, during the developing process of this proposal, it was taken into consideration the evaluation of preconditions and postconditions of these assets and security policies in the IT infrastructure to evaluate the risks and show the input of the new updates and changes (see Table 4).…”

Advancements in digital technologies have significantly enhanced the functional capabilities of consumers and businesses alike, yet have concurrently amplified the complexities associated with cybersecurity, including theft and cyber-attacks. Consequently, auditing of information systems has emerged as a crucial security apparatus for organizations aiming to safeguard their data assets, specifically with respect to customer information. This study aims to design an information systems security and audit model that emphasizes the fortification of an organization's crucial assets via IT infrastructure security and information security management systems, in alignment with ISO 27001 standards. The proposed model seeks to assure information confidentiality, integrity, availability, and compliance with legal mandates. The study adopted the OCTAVE v2.0 method, executed in three distinct phases. In the first phase, profiles of asset-based threats were constructed. The second phase involved the identification of infrastructure vulnerabilities, whereas the final phase focused on the development of a security strategy and plans. The implementation of the proposed model yielded a marked impact, with a positive shift from 46% to 94% following the establishment of IT infrastructure security policies. The study underscores the importance of conducting a comparative analysis prior to implementation and asserts that well-defined and identified security models and information systems auditing can effectively counteract potential data leaks and cyber-attacks such as malware, phishing, spam, and ransomware. The findings suggest that a meticulous and preemptive approach to auditing and security planning can significantly bolster the resilience of an organization's digital infrastructure.

The current study deals with simulation of 3D-flow around three different types of bridge pier shapes on a flatbed surface. The main objective of this article is to explore how water flows around various types of bridge piers. In this article, the CFD-Fluent (k-epsilon) turbulence model was used to simulate the flow turbulence around untraditional piers named upstream facing aero-foiled shaped pier (US-FASP) and downstream facing aero-foiled shaped pier (DS-FASP) and were compared with the circular pier, Results from the experiments were compared to the expected flow velocity (m/s), turbulent kinetic energy (TKE), and other variables. The results of the threedimensional simulation of the water flow behavior and turbulent kinetic energy around the three various designs of bridge piers support that. The findings suggest that (DS-FASP) is the most effective sort of form to employ since it allows water to flow around it extremely smoothly, resulting in minimal obstruction of the water flow in addition to the lowest TKE. In this investigation, root mean errors were used. mean squared errors (MSE), mean absolute errors (MAE), and both the correlation coefficient (R) and the root mean square error (RMSE). The findings also demonstrated that the type of form (DS-FASP) outperformed pavements with other diverse shapes in terms of performance. From this, it was found that the turbulent kinetic energy (TKE) and longitudinal velocity (u) had mean least square errors (MSE) of 1.5E-0 and 7.6E-08, respectively, and coefficients (R 2 ) of 0.92 and 0.98. The shape of a wake vortex in a wake region is captured by the (k-epsilon) model. The k-epsilon turbulence model showed good similarities with the experimental results. The study's findings suggest that local cleaning in the vicinity of bridge piers can be scaled back in the future.

“…Many researches made in recent years at metallurgical plants testify that working conditions were and keep being hazardous and injurious [1,2]. Commonly, workers in metallurgical facilities are exposed to a complex of hazardous agents during all working hours: high noise level, dust and gas pollution [3]. To assess working conditions, it becomes necessary to take into account the combined influence of the above factors.…”

The objective of this work was to present the results of a comprehensive hygienic assessment of the occupational hazards in the ferroalloy production of a metallurgical plant. For the purpose of evaluating occupational hazards, we used data on the injury potential and occupational agents involved in working conditions, safety indicators for production facilities, occupational diseases, and the provision of workers with personal protective equipment. The assessment of occupational hazards demonstrated that for each of the occupations studied the occupational risk is equal to level 3, which means an average degree of risk. As a result of the research, the working conditions of the main occupational groups of the ferroalloy facility were evaluated as hazardous and injurious 3rd class of the 1st grade. After the intervention, it appeared that the workers were exposed to hazardous occupational noise. Acoustic equivalent levels at working places of the charge smelter, a crane operator, a senior melting operator, a furnace operator ranged from 85 to 87 dBA, which exceeds the maximum permissible level by 5-7 dB. Mathematical data processing showed that the distribution of noise in the working areas obeys a polynomial dependence. This paper provides recommendations on the implementation of a risk-oriented approach to the provision of personal protective equipment.
