Green methods that are used to ensure the sustainable development of the environment and the society

Nowadays, pollution is one of the biggest challenges for human society. Many types of research are directed toward finding sustainable solutions with minimum or no environmental impact. The contaminants affect the ecosystem components and the people's health equally. Cardiovascular and cancer are only two examples of diseases for which air and food adulteration are directly influenced. For each situation, the conditions need to be evaluated. Environmental accidents or rehearsal ones can determine the risk sources. Regardless of the case, prevention measures are always recommended. Different organic wastes recovery represents a possible solution ensuring an endurable process. Such an approach has to be also looked at from an economic point of view. Renewable natural raw materials usually have lower costs. Independent of the considered strategies, they all have to be based on two pilings. One acts by the authority’s involvement using legislation and standards, and the other refers to society through awareness and implication. The paper highlights some of the most recent and significant findings regarding eco-friendly and sustainable techniques newly developed that were presented in recently published articles. The topics considered essential for this approach regarded the improvements made to increase the city life, the industrial environment, and the laboratory techniques.

Assessment of risks constraining the sustainable development of forest ecosystems in the Saïda Mountains (Algeria) by using FMECA approach

Mountain forest ecosystems and other biodiversity reserves represent “safety nets” for many communities for their livelihoods. They are economi-cally important sources of wood, fodder, food and non-wood forest prod-ucts. Controlling. the sustainable management of forest ecosystems neces-sarily involves identifying and assessing their condition and circumstance. The method chosen to set the prerequisites for a strategy to safe-guard the cork oak forests, is the one used to identify failures in systems: Failure Mode Analysis and Criticality Evaluation (FMACE). The results sought are recorded in a matrix based on the following points: Identification of hazard and risk sources; Segmentation of the factors causing hazards; Risk evaluation (severity, frequency, non-Detection) (BOUCHAOUR-DJABEUR,2020). The use of the Failure mode effects and criticality analysis approach (FMECA) dedi-cated to risk management for the identification and assessment of risks is possible and highly appreciated. In order to understand the degradation pro-cess of forest formations in Saida Mountains (Algeria), two matrices from modified FMECA method allowed identification of 15 main defective targets. Identified failures have been grouped into 5 categories namely: organization-al, technical, professional, management and socio-economic in order to facil-itate their remediation. For each failure, a score was assigned, allowing clas-sification of breaches in order to set up an action plan based on priorities. Results from our present evaluation study based on the FMECA approach will allow various actors of forest and mountain domain to better under-stand the degradation of this natural space and help to make decisions and undertake valid remediation actions.

An Environmental Risk Assessment of Filling Stations Using the Principles of Security Management. A Case Study in the Slovak Republic

The issue of environmental risk assessment currently deserves great attention. In order to protect the environment, maintain healthy living conditions, and prevent environmental damage, the member states of the European Union have adopted a Directive of the European Parliament and of the Council on environmental liability with regard to the prevention and remedying of environmental damage. The directive classifies two types of operators with different liability regimes for environmental damage, namely, the regime with no-fault (strict) liability and liability for fault. With the adoption of the directive, among experts, operators and the general public have posed questions about how to assess the risk of environmental damage. At present, there is still no uniform procedure for assessing environmental risks, which would create a comprehensive methodological framework for assessment for this type of risk. Due to the non-existent risk assessment methodology for operators with strict liability regimes and the lack of a systematic search for risk sources, a risk assessment procedure is proposed that provides guidance in a sequence of several steps on how to implement the obligations arising from the adopted Environmental Liability Directive. The proposed procedure was verified on a specific operator with a strict liability regime. The environmental risk analysis performed through the proposed procedure provided information on possible operational problems and verified its applicability. Last but not least, the use of the proposed procedure makes it possible to identify serious sources of risk and to establish necessary preventive measures to prevent the occurrence of environmental damage.

Antimicrobial Resistance of Aeromonas Species Isolated from Cultured Indian Major Carp, Labeo rohita: Possible Public Health Concern

In India, Labeo rohita is widely cultured and consumed freshwater fish. Aeromonads are etiological agents of major bacterial fish diseases like furunculosis, haemorrhagic septicaemia, skin ulcers, fin/tail rot and dropsy, causing significant economic losses in carp culture. Aeromonas species are widely distributed in aquatic environment which is considered as important vehicle of Aeromonas infections to fish and humans. Some of the Aeromonas spp. causes gastroenteritis, septicaemia, peritonitis, meningitis and eye infections in humans. In the present study Aeromonas species were isolated from diseased freshwater fish Labeo rohita collected from two districts viz., West Godavari and SPSR Nellore of Andhra Pradesh, India. A Total of 12 Aeromonas spp. were isolated and identified by biochemical tests. A. veronii bv. veronii (35%) was dominant when compared to other Aeromonas spp. Further, Antimicrobial resistance and multiple Antimicrobial resistance (MAR) of all Aeromonas spp. were tested against 17 antibiotics being frequently used for human diseases. The Antimicrobial resistance of all the 12 Aeromonas spp. have shown significantly high (p<0.05) resistance (100%) to ampicillin, amoxyclave and oxytetracycline except A. cavernicola when compared to other antibiotics. The MAR index of Aeromonas spp. ranged from 0.18-0.76, which indicates origination of isolated Aeromonas spp. from high risk sources of contamination. A. hydrophila, A. veronii bv. sobria, A. veronii bv. veronii, A. schubertii and A. jandaei isolated in this study were found to be pathogenic to humans also. The results revealed the pathogenic potential of Aeromonas infections in freshwater fish culture and emerging threats to public health.

Integrated Environmental Risk Assessment of Major Accidents in the Transport of Hazardous Substances

At present, the environmental risk assessment of major accidents is mainly carried out for stationary risk sources. Only marginal attention is paid to mobile risk sources, while the currently available methodologies require a relevant expertise and time for their application, which is only partially possible in most scenarios. In the present study, an integrated approach to environmental risk assessment in the transport of hazardous substances (iTRANSRISK) was developed. The approach proposed is based on the principle of index-based assessment of leakage scenarios involving toxic and flammable substances during transport, in the context of indexing environmental vulnerability. The key point of the method is the conversion of local-specific data concerning the risk potential of the transported substance, the consequences and the probability of a major accident, and environmental vulnerability assessment into a single entity. The created integral approach is proposed for the needs of carriers of the hazardous substances and the state administration bodies. The proposed approach is determined for the screening risk assessment at the beginning of the process of the planning a suitable transport routes and the results are for information only. An example of the application of the iTRANSRISK integrated approach is demonstrated considering an explosion scenario following a propane tanker leak (18 t) in a forested area, with moderately susceptible soils and no surface water or groundwater affected.

Sterilization of Paper During Crisis

Paper sheets represent one of the infection risk sources inside many institutions. The present study aimed to validate the sterilization efficiency of contaminated paper sheets with different indicator pathogens by gamma radiation or dry heat technique with retaining their structure. The results show that gamma irradiation at 6 kGy, 12 kGy, and 24 kGy can successfully kill Gram-positive bacteria like Bacillus cereus and Staphylococcus aureus, Gram-negative bacteria like Escherichia Coli and Salmonella typhi, and fungi such as Candida albicans. Moreover, dry heat at 100°C for 1 hour, 150 for 30 min, or 200 for 15 min can be successful in paper decontamination completely all tested species. Surprise, micrographs of scanning electron microscope (SEM) proved that a radiation dose of 6 kGy, dry heat at 100°C for 1 hour, 150 for 30 min or 200 for 15 min is suitable for paper sheets sterilization with maintaining their structure. Ultimately, dry heat or γ-radiation as simple, useful, effective, fast, safe, and inexpensive techniques. It may be used as a precautionary step inside educational institutions especially, during written examinations period to ensure safe life for academic members during biological pandemics like covid-19.

Security Challenges in Industry 4.0 PLC Systems

The concept of the fourth industrial revolution assumes the integration of people and digitally controlled machines with the Internet and information technologies. At the end of 2015, more than 20 billion machines and devices were connected to the Internet, with an expected growth to half a trillion by 2030. The most important raw material for this digital revolution is data, which when properly stored, analyzed and secured, constitute the basis for the development of any business. In times of rapid industrial development, automation of production processes and systems integration via networks, the effective protection of the cyber-physical systems of a plant is particularly important. To minimize the risks associated with Internet access, one must define all the possible threats and determine their sources in the plant and block or minimize the possibility of sabotage or data loss. This article analyzes the security measures used in industrial systems. In particular, risk management and the study of the risk sources in terms of human, hardware and software aspects in networked PLC and SCADA systems are discussed. Methods of improving the architecture of industrial networks and their management are proposed in order to increase the level of security. Additionally, the safety of the communication protocols with PLCs in industrial control systems is discussed.

The results of HOR 2 analysis show eight priority management strategies that can be implemented by PDP Kahyangan Jember.

Occupational Health and Safety Risk Assessment of Cruise Ship Construction Based on Improved Intuitionistic Fuzzy TOPSIS Decision Model

The logistics of cruise ship construction are complex, with an extended period, many participants, and a stringent node control. The resulting occupational health and safety risks have more risks and uncertainties. If it is not identified and controlled, it will lead to low efficiency of logistics management in the construction stage, leading to chain breaking and going out of control. In response to this situation, this article proposes an improved intuitionistic fuzzy TOPSIS decision model to evaluate occupational health and safety risks in cruise ship construction. First, based on field research and interviews, risk sources and risk evaluation criteria are determined, and experts are given different weights based on the relative importance of decision-making experts. Then, to reduce the ambiguity and uncertainty of the risk source information, the intuitionistic fuzzy weighted arithmetic average operator is used to aggregate the judicial opinions of experts to obtain the intuitionistic fuzzy aggregate decision risk matrix. To improve the accuracy of risk assessment results, subjective weight and objective weight are comprehensively considered. The stepwise weight assessment ratio analysis (SWARA) method is used to determine the subjective weight of the evaluation criteria, and the normal distribution method is used to determine the objective weight of the evaluation criteria. According to the relative closeness coefficient of each risk source to the positive-ideal solution, the ranking of the risk sources is obtained. Finally, taking a cruise ship construction as an example, the risk sources of occupational health and safety are sorted, sensitivity analysis is carried out and compared with other methods, and the targeted risk control measures are put forward, which verifies the effectiveness and correctness of the improved intuitionistic fuzzy TOPSIS decision model.
