Influencing Factors, Risk Assessment, and Source Identification of Heavy Metals in Purple Soil in the Eastern Region of Guang’an City, Sichuan Province, China

Soil heavy metal contamination poses a significant threat to both environmental health and ecological safety. To investigate the influencing factors, ecological hazards, and sources analysis of heavy metals in purple soil, 27 sets of soil samples were collected from varying genetic horizons within Guang’an City, and the contents of As, Cd, Cu, Cr, Hg, Ni, Pb, and Zn were analyzed. The results indicated higher concentrations of heavy metals in soil A horizon, compared to that of C horizon. The relevance analysis indicated that the soil’s heavy metals were strongly correlated with the soil’s physicochemical properties. The enrichment factor, pollution load index, and potential risk index highlighted slightly to severely polluted levels of soil Cd and Hg, which significantly contribute to the ecological hazards posed by soil heavy metals. The potential source of heavy metals analyzed using the APCS-MLR model identified both anthropogenic inputs and natural sources as primary contributors to heavy metal presence in soils. The Cu, Cr, Ni, Pb, and Zn contents in the samples from different genetic horizons were chiefly influenced by natural sources, such as soil matrix erosion and weathering, while the concentrations of Cd and Hg were largely affected by anthropogenic activities, specifically coal combustion and agriculture. Conversely, the As content was found to be influenced by a combination of both factors. Anthropogenic activities greatly impacted soil heavy metals at various depths within the study area, thereby underscoring the importance of monitoring these heavy metals. The findings gained from this research can give a scientific basis for the potential utilization of purple soil.

Liquid-Phase Exfoliated Graphene and Polytetrafluoroethylene for Highly Durable and Reusable Chemical Leak Detection Sensors

Graphene-based chemical sensors hold promise across diverse applications owing to their exceptional sensitivity and selectivity. However, achieving their long-term durability and reusability while preserving high sensitivity remains a significant challenge, particularly in harsh environments where exposure to strong chemicals is inevitable. This paper presents a novel approach to address this challenge by synergistically integrating liquid-phase exfoliated graphene (LPEG) with polytetrafluoroethylene (PTFE) within a single sensing strip. Through a comprehensive experimental investigation, we demonstrate the fabrication of highly durable and reusable chemical leak detection sensors by combining LPEG and PTFE. Furthermore, we explore the sensing mechanism, highlighting the roles of LPEG and PTFE in enhancing sensitivity and selectivity, along with durability and reusability. Performance evaluation reveals the sensors’ robustness against mechanical and chemical degradation, coupled with excellent recyclability. This innovative approach holds promise for applications in environmental monitoring, industrial safety, and healthcare, thus advancing the field of graphene-based chemical leak detection sensors.

Methodology to Increase the Efficiency of the Mineral Water Extraction Process

The most important source of human life support is water. During the development of mineral water fields, unsustainable patterns of production and consumption have been observed, which could lead to environmental damage and the deterioration of mineral water quality and sources. In this work, a procedure for determining the modified link’s parameters, replacing the static and dynamic indicators of the hydrodynamic process, is proposed. Recording the parameters at the different filtration coefficients along the spatial coordinates allows the environmental safety of aquifers to be increased and the pressure of the reservoir to be stabilized. The presented approach allows the accuracy of the process used to control the reservoir’s pressure to be increased.

Theoretical and legislative approaches to the use of certain terms and concepts in the field of environmental safety

The scientific article highlights the legislative and theoretical approaches to the use of certain terms and concepts in the field of environmental safety, on the basis of which proposals are made for their optimal use in the relevant normative legal acts and in scientific circulation. It is noted that the stability of information and legal support, including in the environmental sphere, is possible subject to the unification of legislative terms, a clear normative consolidation of their content in order to have the same understanding and application in practice. It is concluded that the identification of the concepts of “ecology” and “environment” is erroneous, because “ecology” is that part of it that concerns the natural component of the environment. In this regard, as well as in view of the need to bring national legislation to international standards in the sphere under study, it is more appropriate to use the synonymous term “environment” for the concept of “environment,” which would cover not only the natural component, but also the habitat of mankind as a whole. Arguments are given that the most acceptable title of the relevant section (Book) of the future criminal law, which would take into account the content and meaning of the terms used in it, characterizing first of all the generic object of criminal offenses in the studied sphere, is the title “Criminal offenses against nature and environmental safety.” Such a structural unit of the Special Part of the Criminal Code of Ukraine should contain both criminal offenses against environmental safety and torts against the environment, which are actually identified with criminal violations against the use of natural resources. After all, individual acts in this area can encroach both on relations against environmental safety and on the order of use of the state’s natural resources, while directly or indirectly affecting public health.

Evaluation of urban ecological security model based on GIS sensing and MCR model

Urban ecological security is not only a basic safety requirement for human security and development, but also an important part of national security and other security and infrastructure carriers. Protecting the environment is an important factor in the construction of China's natural civilization. In recent years, with the deterioration of the environment, the region and its people have paid more and more attention to the safety of urban ecological environment, which has become one of the hottest issues in current research. Land use/cover rate change (LUCC) affects the environment, which will also affect environmental safety, and changes in its appearance will also affect nature and the environment, providing a positive impetus for the control of natural processes. In this paper, researches on the above problems in City K and Zhengzhou are carried out, using MSPA and visual image forms to better connect local resources, and through the MCR model based on ecological control, a weight-based multi-structure network model is established, which is conducive to the establishment of a multi-structure network model based on ecological control. Build a city of environmental science network. The GIS control line was explored, and the concept of the control line was filled to a certain extent. At the same time, taking City K and Zhengzhou as examples, determining the breadth of their layout and management, as well as the control strategy of their environmental control lines, provides a specific reference angle for the layout and research of other cities. Urban ecological security is very important to each of us living in cities. It is a difficult problem at this stage to establish an ecological security model to open a new security pattern.

Efficient porphyrin integrated UiO-66 probes for ratiometric fluorescence sensing of antibiotic residues in milk.

Dual-emissive fluorescence probes were designedby integrating porphyrin into the frameworks of UiO-66 for ratiometric fluorescence sensing of amoxicillin (AMX). Porphyrin integrated UiO-66 showed dual emission in the blue and red region. AMX resulted in the quenching of blue fluorescence component, attributable to the charge neutralization and hydrogen bonds induced energy transfer. AMX was detected using (F438/F654) as output signals. Two linear relationships were observed (from 10 to 1000nM and 1 to 100µM), with a limit of detection of 27nM. The porphyrin integrated UiO-66 probe was used to detect AMX in practical samples. This work widens the road for the development of dual/multiple emissive fluorescence sensors for analytical applications, providing materials and theoretical supporting for food, environmental, and human safety.

Legal terminology in environmental and land law: theoretical-legal analysis

The article examines the peculiarities of the formation of legal terminology in the field of environmental and land law and proves the feasibility of its improvement in connection with the adaptation of the norms of national law to the law of the European Union. The article states that today in Ukraine there is significant environmental pollution, climate change, land deterioration, which significantly worsened in connection with the military aggression of the Russian Federation and caused a particularly dangerous ecological situation in the country. The article proves that the implementation of the principles of the right of citizens to a safe environment, ensuring human safety, protection and rational use of land, forest, water and subsoil resources is not possible without a clear definition of legal prescriptions enshrined in the law. The article states that one of the important aspects of the language of law is legal terminology, which makes it possible to formulate the content of a legal document. The article defines the concepts of “terminology”, “terminology”, “legal terminology”. It is noted that it is not appropriate to equate the concepts of “terminology” and “terminological system”. It has been investigated that despite the presence of established terminology in environmental law, the presence of terms in need of improvement is observed in this field, namely: “ecological law” and “environmental law”. It has been proved that for the purpose of further codification of environmental law, it seems appropriate to use the term “environmental law” as an established term of EU legislation. It has been analyzed that today the language of the law in the field of land relations is gaining importance, which is due to the formation of the land market in Ukraine and the need to adapt the norms of land law to EU law. It is noted that in land law there is a problem of identifying the terms: “land”, “land plot”. It was noted that the legal terms related to the formation of the land market in Ukraine need improvement and detailing. It was concluded that legal terminology in the field of environmental and land law is one of the important aspects of the development of the language of law. The issue of improving legal terminology in the field of environmental and land law is one of the necessary steps that will contribute to the unification and harmonization of the legal norms of the specified fields in the context of adapting the norms of national law to EU law.

Exploration of virtual reality as a tool for simulating leadership and teamwork situations among university students

In the current educational context, virtual reality emerges as a revolutionary tool. By immersing students in immersive simulated environments, it facilitates deep understanding of abstract concepts and practical application of knowledge. The present study seeks to analyze the application of virtual reality as a tool to improve leadership and teamwork skills among university students through a literature review. A literature review of existing literature on the topic of virtual reality and its application in higher education was carried out, focusing specifically on studies that address the simulation of leadership and teamwork situations. Relevant research that provided insight into the benefits and challenges of VR in this context was selected and reviewed. The results of the literature review revealed a variety of studies that support the potential of virtual reality to improve the leadership and teamwork skills of university students. Virtual reality has been found to provide immersive experiences, safe environments, and immediate feedback that promote the development of these skills. However, challenges such as assessing the impact and accessibility of the technology have also been identified.

Genetic recombination-mediated evolutionary interactions between phages of potential industrial importance and prophages of their hosts within or across the domains of Escherichia, Listeria, Salmonella, Campylobacter, and Staphylococcus

BackgroundThe in-depth understanding of the role of lateral genetic transfer (LGT) in phage-prophage interactions is essential to rationalizing phage applications for human and animal therapy, as well as for food and environmental safety. This in silico study aimed to detect LGT between phages of potential industrial importance and their hosts.MethodsA large array of genetic recombination detection algorithms, implemented in SplitsTree and RDP4, was applied to detect LGT between various Escherichia, Listeria, Salmonella, Campylobacter, Staphylococcus, Pseudomonas, and Vibrio phages and their hosts. PHASTER and RAST were employed respectively to identify prophages across the host genome and to annotate LGT-affected genes with unknown functions. PhageAI was used to gain deeper insights into the life cycle history of recombined phages.ResultsThe split decomposition inferences (bootstrap values: 91.3–100; fit: 91.433-100), coupled with the Phi (0.0-2.836E-12) and RDP4 (P being well below 0.05) statistics, provided strong evidence for LGT between certain Escherichia, Listeria, Salmonella, and Campylobacter virulent phages and prophages of their hosts. The LGT events entailed mainly the phage genes encoding for hypothetical proteins, while some of these genetic loci appeared to have been affected even by intergeneric recombination in specific E. coli and S. enterica virulent phages when interacting with their host prophages. Moreover, it is shown that certain L. monocytogenes virulent phages could serve at least as the donors of the gene loci, involved in encoding for the basal promoter specificity factor, for L. monocytogenes. In contrast, the large genetic clusters were determined to have been simultaneously exchanged by many S. aureus prophages and some Staphylococcus temperate phages proposed earlier as potential therapeutic candidates (in their native or modified state). The above genetic clusters were found to encompass multiple genes encoding for various proteins, such as e.g., phage tail proteins, the capsid and scaffold proteins, holins, and transcriptional terminator proteins.ConclusionsIt is suggested that phage-prophage interactions, mediated by LGT (including intergeneric recombination), can have a far-reaching impact on the co-evolutionary trajectories of industrial phages and their hosts especially when excessively present across microbially rich environments.

Early grade teachers’ professional development programs for promoting school safety: Does it make a difference?

This study explored the influence of training on helping teachers to promote greater school safety. A qualitative case study design was adopted, and 213 early grade teachers from Tanzania Mainland and Zanzibar took part in the study. Data were gathered through individual semi-structured interviews before being thematically analysed. It was evident that teachers were inadequately prepared in terms of autonomy and supportive communication to help their pupils develop crucial skills for creating a safe learning environment. In- service professional development programs related to social and emotional learning would enhance teachers’ ability to support their pupils to address school safety concerns.

REAL TIME AIR QUALITY PREDICTION AND ANOMALY DETECTION

When it comes to addressing the growing concerns about environmental health and safety, real-time air quality forecast and anomaly detection are essential. This study describes a robust system that effectively tracks, analyses, and forecasts air quality parameters in real-time using a combination of cutting-edge sensors, sophisticated data analytics, and machine learning algorithms. Utilising a wide range of environmental sensors, the system continuously monitors pollutants such as carbon monoxide, nitrogen dioxide, sulphur dioxide, particulate matter (PM2.5 and PM10), and ozone. Modern data analytics techniques are then used to process and analyse the gathered data. A machine learning platform at the centre of the system makes use of time-series forecasting methods to forecast air quality conditions. Additionally, it uses anomaly detection algorithms to identify anomalous trends or abrupt spikes in pollutant concentrations, which may indicate operational issues or environmental dangers. Environmental agencies and public health experts can take timely action and make informed judgements thanks to these skills. In addition, the system has an easy-to-use interface that provides both specialists and non-experts with real-time updates and visual representations of air quality statistics. Using IoT technology increases the system's expandability to larger regions and guarantees effective data flow. By providing consistent and accurate air quality information, this technique not only supports urgent mitigation measures but also facilitates strategic environmental and public health planning. Predictive analytics and proactive surveillance are intended to improve environmental governance and public health. Keywords—LSTM, Linear Regression and Minmax scalar.

Construction of fungicide nano delivery platform through crystal engineering for sustainable fungal control

The adverse effects resulting from off-target pesticide application pose significant risks to both ecosystems and public health. Therefore, developing a pesticide delivery system that is straightforward, effective, and devoid of secondary pollution is crucial for environmental safety. Herein, self-assembled crystalline materials involved pyrimethanil (PYR) and organic acids were constructed by crystal engineering. These materials allowed for direct manipulation of the physicochemical properties and environmental fate of PYR by the building modules. The melting point of PYR was increased from 96.19 °C to 206.69 °C. The photostability and volatile stability were improved by 3.85-fold and 297-fold, respectively. Afterwards, these crystalline materials were prepared as nano cocrystal suspensions (NCSs) in water by the one-pot method. The PYR NCSs exhibited potent bioactivity against Botrytis cinerea and demonstrated slow-release behavior. Upon foliar spraying, the PYR NCSs exhibited desirable foliar wettability with a contact angle lower than 36°. By limiting leaching into the soil and reducing environmental pesticide exposure, PYR NCS ensured the safety of both earthworms and plants. The structure–property relationships of PYR NCSs were elucidated through intermolecular interaction analysis and theoretical calculations. Overall, the NCSs constructed by the supramolecular chemistry strategy are characterized by the simple preparation, high bioactivity, stability, no carrier, slow-release, and minimal environmental risk, which offers insight for improving the utilization and sustainable management of pesticides.

Practical recommendations are provided based on the evaluation of research findings, aiming to enhance the implementation of environmental laws. The goal is to strengthen environmental safety and promote sustainable development in Saudi Arabia. The outcomes of this study hold significant importance for policymakers, aiding in the reinforcement of law enforcement and the encouragement of sustainable practices adaptable to local contexts, while also contributing to global environmental initiatives.

Navigating occupational safety and health challenges in sustainable infrastructure projects: a comprehensive review

Ensuring occupational safety and health (OSH) is paramount in infrastructure projects due to their inherently high-risk nature and the increased likelihood of accidents. Despite its importance, numerous obstacles impede the successful adoption of OSH measures in these settings. Addressing these challenges is key to not only implementing OSH protocols effectively but also to improving working conditions and managing other operational facets like quality and environmental concerns, ultimately resulting in better infrastructure developments. Adopting proactive OSH strategies is crucial for preventing significant accidents and fostering a safety culture within infrastructure projects. This review focuses on identifying the primary obstacles and barriers to effective OSH in infrastructure projects, laying the groundwork for improving safety performance in the sector. It highlights organizational and legislative issues as the foremost challenges due to their direct impact on safety culture, resource distribution, compliance, and accountability. Although factors related to environmental and safety practices are deemed less critical, they are nonetheless vital for comprehensive risk management and the promotion of a safe working environment. Tackling these issues is imperative for cultivating a strong safety culture and safeguarding the health of workers on infrastructure projects. It is also essential to acknowledge the distinct OSH challenges presented by different construction scenarios to devise customized safety measures and effectively reduce risks. This review emphasizes the necessity of recognizing the unique aspects of each construction project, addressing specific dangers, and meeting regulatory demands to achieve thorough safety management.

The Impact of Change Orders Caused by Legislative Changes on Program Management in the UAE Construction Industry

Program management is an important strategy for organizing and managing multiple interdependent construction projects to achieve strategic goals. However, when change orders occur, they can have a serious impact on the quality, time, cost of projects and, ultimately, affect the construction program. Furthermore, when change orders are caused particularly by legislative changes, such as environmental laws, taxes, tolls, safety codes, transportation, design or building codes, their impacts are unavoidable, yet can be managed through mitigation strategies. The existing literature only reports the implications of change orders on the project level and reports legislative changes as one of the contributing factors to change orders, but does not consider the implications on a program level. This study aims to close this knowledge gap by assessing the implications of change orders caused by legislative changes on program management in the construction industry during the construction phase, and explore what the possible mitigation strategies to manage change orders caused by legislative changes are. The objectives of the study include identifying the implications of change orders on construction projects in the UAE through a literature review using peer-reviewed journals and reliable industry sources. Additionally, we investigate the implications of change orders caused by legislative changes on construction programs through interviewing subject matter experts, evaluating the importance of the reported impacts, with possible mitigation strategies, through a structured questionnaire and Relative Importance Index (RII) and, finally, proposing a set of recommendations for key industry stakeholders. A mixed methods approach is adopted in this qualitative study, and the participants include clients, contractors and consultants from the construction industry, with a defined scope covering the construction stage only. The outcomes of the study can guide program managers, decision-makers and practitioners in the construction industry to successfully deliver all projects by directing proper resources to accommodate legislative changes.

Ensemble multiclassification model for predicting developmental toxicity in zebrafish

In recent years, with the rapid development of society, organic compounds have been released into aquatic environments in various forms, posing a significant threat to the survival of aquatic organisms. The assessment of developmental toxicity is an important part of environmental safety risk systems, helping to identify the potential impacts of organic compounds on the embryonic development of aquatic organisms and enabling early detection and warning of potential ecological risks. Additionally, binary classification models cannot accurately classify organic compounds. Therefore, it is crucial to construct a multiclassification model for predicting the developmental toxicity of organic compounds. In this study, binary and multiclassification models were developed based on the ToxCast™ Phase I chemical library and literature data. The random forest, support vector machine, extreme gradient boosting, adaptive gradient boosting, and C5.0 decision tree algorithms, as well as 8 types of molecular fingerprint were used to establish a multiclassification base model for predicting developmental toxicity through 5-fold cross-validation and external validation. Ultimately, a multiclassification ensemble model was derived through a voting method. The performance of the binary ensemble model, as measured by the balanced accuracy, was 0.918, while that of the multiclassification model was 0.819. The developmental toxicity voting ensemble model (DT-VEM) achieved accuracies of 0.804, 0.834, and 0.855. Furthermore, by utilizing the XGBoost machine learning algorithm to construct separate models for molecular descriptors and substructure molecular fingerprints, we identified several substructures and physical properties related to developmental toxicity. Our research contributes to a more detailed classification of developmental toxicity, providing a new and valuable tool for predicting the developmental toxicity effects of unknown compounds. This supplement addresses the limitations of previous tools, as it offers an enhanced ability to predict potential developmental toxicity in novel compounds.

Synthesized Gold Nanoparticles with Moringa Oleifera leaf Extract Induce Mitotic Arrest (G2/M phase) and Apoptosis in Dalton's Lymphoma Cells.

The therapeutic potential of chemically synthesized AuNPs has been demonstrated in various types of cancer. However, gold nanoparticles (AuNPs) synthesized using typical chemical methods have concerns regarding their environmental safety and adverse impact on human well-being. To overcome this issue, we used an environmentally friendly approach in which gold nanoparticles were synthesized using Moringa oleifera leaf extract (MLE). The present research was mainly focused on the biosynthesis and characterization of gold nanoparticles (AuNPs) using Moringa oleifera leaf extract (MLE-AuNPs) and explore its anticancer potential against Dalton's Lymphoma (DL) cells. Characterization of the MLE-AuNPs was conducted using UV-Vis Spectroscopy to confirm the reduction process, FTIR analysis to ascertain the presence of functional groups, and XRD analysis to confirm the crystallinity. SEM and TEM images were used to examine size and morphology. After characterization, MLE-AuNPs were evaluated for their cytotoxic effects on Dalton's lymphoma cells, and the results showed an IC50 value of 75 ± 2.31 µg/mL; however, there was no discernible cytotoxicity towards normal murine thymocytes. Furthermore, flow cytometric analysis revealed G2/M phase cell cycle arrest mediated by the downregulation of cyclin B1 and Cdc2 and upregulation of p21. Additionally, apoptosis induction was evidenced by Annexin V Staining, accompanied by modulation of apoptosis-related genes including decreased Bcl-2 expression and increased expression of Bax, Cyt-c, and Caspase-3 at both the mRNA and protein levels. Collectively, our findings underscore the promising anti-cancer properties of MLE-AuNPs, advocating their potential as a novel therapeutic avenue for Dalton's lymphoma.

Examining property and neighborhood effects on perceived safety in urban environments: Proximity to square and heights of buildings

Residents' perceived safety is key to improving livelihoods and reducing disparities between neighborhoods in Sweden. Neighborhood interventions may be more cost-effective than individual-level interventions in addressing major societal issues such as unequal levels of safety between neighborhoods. However, most studies investigating the impact of neighborhood characteristics on perceived safety suffer from either poor data quality, too few respondents per statistical unit, large units of analysis, or a lack of longitudinally collected data. This study aims to fill this gap by combining property-specific longitudinal sociodemographic data with customer satisfaction survey data (N = 147,965) collected between 2013–2014 and 2016–2021 in Gothenburg. Using two multilevel models, we examined the relationship between perceived safety and both property-level and area-level structural characteristics, testing three hypotheses. Consistent with prior research, we find that sociodemographic and urban environmental characteristics influenced perceptions of safety. The multilevel analyses reveal that proximity to the square is associated with lower levels of perceived safety, particularly among residents living within 0–100 m of the square in socioeconomically disadvantaged neighborhoods. Moreover, the results show that living in taller buildings of 10–16 floors is associated with lower levels of safety.

Workplace interventions to prevent suicide: A scoping review.

To map organisational interventions for workplace suicide prevention, identifying the effects, mechanisms, moderators, implementation and economic costs, and how interventions are evaluated. Suicide is a devastating event that can have a profound and lasting impact on the individuals and families affected, with the highest rates found among adults of work age. Employers have a legal and ethical responsibility to provide a safe working environment for their employees, which includes addressing the issue of suicide and promoting mental health and well-being. A realist perspective was taken, to identify within organisational suicide prevention interventions, what works, for whom and in what circumstances. Published and unpublished studies in six databases were searched. To extract and map data on the interventions the Effect, Mechanism, Moderator, Implementation, Economic (EMMIE) framework was used. Mechanisms were deductively analysed against Bronfenbrenner's socio-ecological model. From 3187 records screened, 46 papers describing 36 interventions within the military, healthcare, the construction industry, emergency services, office workers, veterinary surgeons, the energy sector and higher education. Most mechanisms were aimed at the individual's immediate environment, with the most common being education or training on recognising signs of stress, suicidality or mental illness in oneself. Studies examined the effectiveness of interventions in terms of suicide rates, suicidality or symptoms of mental illness, and changes in perceptions, attitudes or beliefs, with most reporting positive results. Few studies reported economic costs but those that did suggested that the interventions are cost-effective. It seems likely that organisational suicide prevention programmes can have a positive impact on attitudes and beliefs towards suicide as well reducing the risk of suicide. Education, to support individuals to recognise the signs and symptoms of stress, mental ill health and suicidality in both themselves and others, is likely to be an effective starting point for successful interventions.

Nurses’ perceptions about management practices of nurse managers during pandemics: a descriptive and cross-sectional study

Introduction: Hospitals may not be able to manage the chaotic environment during pandemics through classical management principles. Management can only be achieved with the help of effective leadership, appropriate flow of crisis management systems, teamwork, and collaboration. Nurse managers should have effective management skills. Objective: To evaluate the perception of the nurse managers' practices by nurses such as resource management, organization, communication, psychosocial, care-training, and decision-making practices in the management of the pandemic based on the COVID-19 pandemic. Methods: A quantitative, cross-sectional method was used, and a web-based online questionnaire was applied to collect data. This study included 182 nurses working in a public and private hospital in İstanbul. Result: The nurses perceived the management practices of their managers at a moderate level. The leaders' resource management practices as low (16.5%), and medium (78.6%) perceive. There was a statistically significant difference (p<0.01) between the communication and team relations (p<0.05), resource management (p<0.01), care-training (p<0.05), and decision-making scores (p<0.01) of the nurses working in the private hospitals compared to those working in the public hospital. Conclusion: To effectively manage a complex and chaotic environment, nurse managers should trust their team, have speed and adaptation skills, be based on human factor principles, and provide a safe working environment. Education should be emphasized so that nurses can work in specialized areas and nurse managers can improve their management skills.
