Published: September 2022

Renewable energy resources become the best way to solve the issues created by traditional power resources in terms of environmental effects, energy cost reduction, and high-power demand. The hybrid-based system gives a realistic economic solution where grid extension is non-feasible especially for remote areas. The main objective of this study is to determine the optimum size of a hybrid-based system to fulfill the requirements of remote sites located in the Hasik area in the southern part of Oman. The work is carried out using HOMER Pro and MATLAB software. The proposed hybrid system in Hasik network is a combination of PV systems with existing diesel generation. Real load data as well as solar radiations were utilized in proposed model. HOMER selected an optimum solution for the hybrid system resulting in a combination of 2,500 kW PV system and 3,100 kW diesel generation as well as providing a reduction in the cost of energy and CO2 emission by 13% and 22% respectively. The optimum PV sizing for the hybrid system was determined using genetic algorithm tool in MATLAB. The optimization was based on reducing the system power losses, improving the voltage profile and minimizing cost. Optimization verification was done using load flow analysis by MATLAB to determine the PV sizing effects on the system power losses and voltage profile. Based on the model results, the hybrid system is feasible in the Hasik area.

CONTEXT
most of the electrical power is generated by thermal power plants. When a thermal plant is operated it can induce carbon dioxide and other toxic gases which can pollute the environment and reduce the life of living nature. Also, the cost of electrical power generation increases if the demand increases.
OBJECTIVE
This work proposed the economic load dispatch, which can help to generate the electrical power as per the load demand and save coal as well as reduce the emission of toxic gases.
METHODS
This work considers the latest variant of particle swarm optimization techniques, which can help to optimize the economic load dispatch. The help of case study shows the effectiveness of ELD and PSO techniques.
RESULTS AND CONCLUSIONS
This article discussed the above-mentioned problem and gave solutions. Taking different case studies and calculating the cost and environmental emission using ELD and optimization techniques. So following the economic load dispatch method for the generation of power in thermal power plants and using suitable optimization techniques, it is possible to reduce the cost as well as emission. If using the green energy system with a thermal power plant system is also economical and free from environmental emissions.

Authors: Yang Zhou , Jia Zhen , Sun Xiaoya , Xu Shuangyan , Zhao Xuefeng , Wang Yisheng , Xu Yan , Li Yuebai
Published: September 2022

Background
Circular RNA was reported tightly associated with the incidence and progress of tumor, including osteosarcoma (OS). Circ_0000530, a newly discovered circular RNA, the expression and function were not investigated in OS until now. Here, we aimed to explore it.
Materials and Methods
By adopting real-time quantitative polymerase chain reaction (qRT-PCR), the level of circ_0000530, miR-198, and cyclin-dependent kinase 6 (CDK6) was identified. Moreover, flow cytometry and transwell assays were adopted for investigating cell cycle distribution, cell migration as well as invasion abilities. Furthermore, using dual-luciferase reporter gene experiments, the correlation between miR-198 and circ_0000530 or CDK6 was revealed. CDK6 protein levels were detected by western blotting (WB). In addition, the impact of circ_0000530 silencing on the growth of OS tumor in vivo was also validated.
Results
Circ_0000530 levels were raised in OS tissues and cells. Besides, it was shown that knockdown of circ_0000530 could hinder the proliferation, migration as well as invasion of OS cells, also inducing cell cycle arrest. Circ_0000530 could be adsorbed to miR-198, and miR-198 inhibitor was capable of reversing the inhibitory impact of silenced circ_0000530 on OS progression. Silencing of circ_0000530 could hinder CDK6 expression whereas miR-198 inhibitor could be used to recover the impact. Apart from that, circ_0000530 knockdown could reduce OS tumor growth through the regulation of CDK6 expression based on miR-198 in vivo.
Conclusion
Down-regulation of circ-0000530 inhibits the development of osteosarcoma through the regulation of miR-198 and CDK6, providing new ideas for diagnosing and treating osteosarcoma.
The Impact of COVID-19 Restrictions on Internship Processes
Authors: Adams Andrea , Mazza Anthony
Published: September 2022

Researchers in different disciplines worldwide have documented the direct impacts of the COVID-19 virus (COVID). Along with the direct effects, the impact of COVID restrictions has changed how students use traditional career readiness programs. Moreover, COVID restrictions act as a "career shock" for student job-seekers. Career shocks are extremely disruptive events that cause individuals to rethink career choices and reflect on their career plans. The global implementation of COVID restrictions has arguably created a "universal" career shock beyond the career shock theory's original foci. Expanding the career shock analysis to include universal disruptions requires a reevaluation of job-seeking methods and opportunities. As a part of rethinking job search methodology through a career shock theoretical lens, this paper focuses on how academic program professors and career center personnel collaborate to support job-seeking students. This research initiated an educational innovation due to the decline in internship availability impacting external interview placement. A non-placement pilot will assist students in completing traditional internship requirements while providing an in-class experiential learning opportunity. This Pilot Course was created as a direct response to the Federal Workforce Development Strategy announced in November 2020. It will use the success factors of adding a non-placement Work-Integrated-Learning (WIL) opportunity within the Practicum course and employ an androgogical, "Differentiated Instruction" design. The study concludes by discussing the future implications of practicum-based internships.

Transformative Reshaping: A Teaching and Learning Practice
Authors: Pearsall III Albert A. , Covington Laurence
Published: September 2022

Transformative Reshaping is a novel, research-based strategic approach to teaching and learning that aims to promote academic and professional success and enhance retention among students. This practice encourages providing students with opportunities to learn how to learn (metacognition), develop technical skills, and acquire essential non-technical abilities or soft skills. The cultivation of competent academicians, professionals, and life-long learners is the ultimate goal. Transformative Reshaping is a SoTL practice that was developed by Albert A. Pearsall III, Assistant Professor of Business at the University of the District of Columbia Community College (UDCCC), and Laurence Covington, Instructor of English, UDCCC from discussions with several college professors, reviews of literature, and classroom trial and error. It is based on the ACUE framework for college-level instruction (ACUE’s effective practice framework).
English at the Intersection
Authors: De Aparajita , Krauthamer Helene , Turpin Cherie Ann , Vilageliu-Diaz Ada
Published: September 2022

This paper discusses how four faculty from the English BA program have responded to the crises faced during 2020 and beyond: the pandemic, the transition to online teaching, and the ongoing struggle for racial justice. First, Dr. Krauthamer provides an overview of the discussions held during our “Read and Meet” series of weekly, virtual conversations, including faculty from other programs and colleges, alumni, current students, and community members. With 24 sessions in 2020, this series resulted in a reading list of Black Lives Matter materials that we are using in our courses and the submission of a grant to the National Endowment of the Humanities. Dr. De presents how we can “understand and reconcile with some blind spots on conversations about identities and their intersections with the complexities of belonging in the 21st century.” In her words, she is concerned with “how can [one] facilitate a conversation on antiracism without also acknowledging the incompleteness of the ontology of race in the US.” Next, Dr. Turpin presents how she teaches by example, demonstrating how, in her words, “Black feminists are in a unique position to fight for a pedagogical practice that is socially progressive so that the next generation of academics will, indeed, come from the very classroom population from where we have taught.” Dr. Vilageliu-Diaz presents how these conversations can be extended to the community through her community writing project, “StoryTime,” a weekly program where children see and create their own stories. In her words, “There are many ways community-engaged writing and teaching can occur, and one of them is by collaborating with schools and supporting their diversity, equity, and inclusion efforts.”
Addressing Challenges of COVID-19 for Virtual College Nutrition Courses with Practicum Components
Authors: Harris B. Michelle
Published: September 2022

A combination of a review of the literature and a survey of practices by fellow Nutrition and Dietetics Program faculty at the University of the District of Columbia were conducted to discover ways to maintain student engagement in practicum courses required for a dynamic undergraduate Didactic Program in Dietetics. This reviewer found through a comprehensive examination of the literature, along with a survey of her program colleagues, that flexibility and planning provide the opportunity for faculty to improve lecture and practicum courses during a pandemic. Emphasis on a high level of engagement enabled students to maintain their ability to apply the theory covered in their nutrition courses to practical problems. This approach will prepare students to enter post-graduate supervised practice and entry into careers as registered dietitians and licensed nutritionists with the confidence and skills that they need to succeed.
A Media Archeology of Education Innovation History and Pandemics
Authors: Hanff Jr. William A.
Published: September 2022

How do we as researchers and educators discern how past institutions of higher education responded to pandemics and other social stresses, and what practices we can adopt from them? Combining Jussi Parikka’s ideas of media archeology with the radical post-colonialism of Nonwestern Educational Traditions by Timothy Reagan, this research explores specific artifacts of western and nonwestern systems of education innovation at specific periods in history, how these institutions responded to crises and pandemics, and what this suggests to our contemporary post-literate networked system of higher education. The emerging field of Media Archeology suggests a literature review mash-up and remix to find under-represented historical ideas around pedagogy and higher education. The impacts of these education innovations are seen through the artifacts such as ‘open plan’ school architecture, educational broadcasting, and proto-internet distance learning classes. Each of these dyads of a western tradition of higher education contrasted with a non-western or resistance tradition of higher education has left artifacts and practices that have been able to escape intentional destruction or cultural appropriation into current western hegemonies. By standing outside the constraints and politics of corporate narratives, these artifacts can point the way toward reviving educational systems based on techniques and technologies that can address the systematic problems with higher education. This study of media, sociology, education, and history seeks to suggest workable practices for a post-COVID world, that resists hegemonic practices and corporatization of education and addresses new challenges in the future.
African American Nurse’s Hesitancy to Obtain COVID-19 Vaccinations
Authors: Broadnax Pier A.
Published: September 2022

It has been over a year since the first laboratory-confirmed case of the Coronavirus -19 disease (COVID-19) was detected in the United States. Since then, according to the Kaiser Family Foundation, there have been over 31, 023,000 citizens diagnosed with the disease, resulting in over 560,315 deaths. Although the rate of citizens being diagnosed with the virus as well as the number of deaths has slowed down since the use of the vaccine, there are still concerns regarding sections of communities and various minority groups who are resistant to obtaining the vaccines. Vaccines first became available in November 2020 in response to this pandemic, but distribution issues and problems with compliance soon became evident and demonstrated an extreme gap in health disparities. As of March 31, 2021, the Kaiser Family Foundation reported that in the District of Columbia, African Americans (AA) make up 46% of the population but 45% of the infected cases as compared to whites who make up 31% of the population but only 26% of the infected cases. Anecdotally, it has been reported that AA nurses are hesitant to obtain the COVID-19 vaccine for a variety of reasons, including fear and mistrust of the medical community. The purpose of this pilot study was to survey a small group of AA nurses to refine a tool that will be used to obtain information on factors contributing to their hesitancy to obtain the COVID-19 vaccination. A secondary purpose is to create educational tools that would be effective in developing messages targeting the concerns of African American nurses.
Thinking Outside of the Academic Box
Authors: Sneed Rosie A.
Published: September 2022

The ongoing COVID-19 pandemic has posed major challenges to education at all levels. Both instructors and students have had to adjust to learning on virtual platforms such as Blackboard. Moving traditional courses online while maintaining high academic standards can be difficult, especially with hands-on laboratory courses. We believed that we could achieve this goal by “thinking outside of the academic box”. The Blackboard learning management system had a number of features we had not used in the face-to-face environment, including the creation of wikis as a substitute for in-class presentations, and journaling as a substitute for paper laboratory reports. Combining these features with the content-rich resources of YouTube and various online educational resources (OER), we developed learning opportunities that met the objectives of two laboratory science courses. We believe this new combination of educational resources should be retained after the resumption of face-to-face instruction.

Published: September 2022

Water diversion infrastructure is characterized by a wide range of impacts and complex geological conditions. There are a large number of risk factors that affect its operational safety. Accidents that have occurred during operation have caused devastaing disasters to water diversion infrastructure. In this study, the failure modes for the operational risks of water diversion infrastructure are identified from four aspects, i.e.,environment, engineering technology, operation management, and society. A failure mode and effect analysis (FMEA) risk poiorization model is established based on the fuzzy inference system (FIS). A fuzzy rule base is established according to IF-THEN rules, and the risk priority is calculated and ranked via FIS. Lastly, a case study of the Huixian section of the Middle Route of the South-to-North Water Transfer Project is carried out to verify the proposed method. The results show that the risks of rainstorms, floods, and foundation failure are regarded as high priority. The validity and applicability of the proposed method are tested via comparison with traditional FMEA. These findings provide valuable information for the operational safety of water diversion infrastructure.

Published: September 2022

Rapid industrialization and continuous mechanization of the food industry
have increased waste production which is a source of various kinds of contaminants
especially emerging water pollutants (EWPs). The industry of food (agriculture and
processed food) and packaging industry are major sources of these emerging pollutants.
Agrochemicals are also a source of pollutants which are contaminating the food chain
and underground water. The dairy and meat industries are source of excess antibiotics,
lactating hormones, medicines (via exudates and effluents), animal fats, acids, sludge,
organic compounds and persisting chemicals in meat and milk. The food processing
industry can also contribute various pollutants, like dyes, preservatives, sanitizing and
disinfecting agents, as well as alcoholic and phenolic residues from the beverage and
wine industries.The food packaging industry is also a major source of food
preservatives, dyes, glue, and non-recyclable/one-time-use materials (plastic and
polystyrene), which can be broken down into micro/nano plastics leading their way to
water reserves and ultimately to the human food chain. Effluents of the food and
packaging industry are rich in organic material and can support the growth of various
pathogenic bacteria and fungi which can become a source of EWPs and can
compromise human health that’s why comprehensive information about these
pollutants is needed. Keeping in mind all of these aspects present draft is compiled.
This chapter covers various aspects of emerging water pollutants released from food relevant industries.
Pharmacophore Modeling Approach in Drug Discovery Against the Tropical Infectious Disease Malaria
Authors: Manhas Anu , Kediya Siddhi , Jha Prakash C.
Published: September 2022

In recent years, the
world has faced several outbreaks caused by viral diseases, resulting in deaths
and comorbidities, harming the health of the population. Due to the “constant”
discovery of new antivirals, vaccines, hygiene habits, and basic sanitation,
society had the false impression of being free from these diseases. However, since
the 1980s, various outbreaks have occurred, such as HIV (Human immunodeficiency
virus) and recently, ZIKV (Zika virus), CHIKV (Chikungunya virus), and EBOV
(Ebola virus) have increased the concern about such pathogens, resulting in
advances in drug discovery. In addition, the SARS-CoV-2 outbreak responsible
for 27,417,497 cases, and 894,241 deaths (to date, September 9th, 2020), showed
how scientists should advance to end this disease so damaging to the global health
and economy. In this context, researches focused on drug development have been
improved in recent years. Thus, it is essential to use computational approaches
to accelerate drug discovery in laboratories. Based on this, structure-based
drug design (SBDD) techniques constitute the most used computer-aided
approaches for discovering and developing new drugs. Among these techniques,
molecular dynamics (MD) simulations have been essential steps and their use in
virtual screening studies is considered indispensable. The MD considers the
macromolecule flexibility using Newtonian principles applied to proteins,
enzymes, membranes, nucleic acids, and other systems. Thus, it is possible to
analyze protein-ligand interactions, and also the affinity energy that a
determined ligand exhibits towards its target. Such information is indispensable
for designing and optimizing new active agents. This chapter will be addressed
to concepts and applications of MD simulations, as well as their applications in
the discovery of drugs against Coronaviruses (SARS-, MERS-CoV, and SARSCoV-2);
Influenza (INFV); Chikungunya (CHIKV); Zika (ZIKV); Dengue (DENV); Ebola
(EBOV); and human immunodeficiency virus (HIV), constituting a great source of
helpful information that could be utilized for designing new compounds against these
diseases.
Development of Principles for Health-Related Information on Social Media: Delphi Study
Authors: Denniss Emily , Lindberg Rebecca , McNaughton Sarah A
Published: September 2022

Background

Health-related misinformation can be propagated via social media and is a threat to public health. Several quality assessment tools and principles to evaluate health-related information in the public domain exist; however, these were not designed specifically for social media.

Objective

This study aims to develop Principles for Health-related Information on Social Media (PRHISM), which can be used to evaluate the quality of health-related social media content.

Methods

A modified Delphi approach was used to obtain expert consensus on the principles and functions of PRHISM. Health and social media experts were recruited via Twitter, email, and snowballing. A total of 3 surveys were administered between February 2021 and May 2021. The first survey was informed by a literature review and included open-ended questions and items from existing quality assessment tools. Subsequent surveys were informed by the results of the proceeding survey. Consensus was deemed if ≥80% agreement was reached, and items with consensus were considered relevant to include in PRHISM. After the third survey, principles were finalized, and an instruction manual and scoring tool for PRHISM were developed and circulated to expert participants for final feedback.

Results

A total of 34 experts consented to participate, of whom 18 (53%) responded to all 3 Delphi surveys. In total, 13 principles were considered relevant and were included in PRHISM. When the instructions and PRHISM scoring tool were circulated, no objections to the wording of the final principles were received.

Conclusions

A total of 13 quality principles were included in the PRHISM tool, along with a scoring system and implementation tool. The principles promote accessibility, transparency, provision of authoritative and evidence-based information and support for consumers’ relationships with health care providers. PRHISM can be used to evaluate the quality of health-related information provided on social media. These principles may also be useful to content creators for developing high-quality health-related social media content and assist consumers in discerning high- and low-quality information.

Monitoring the health status of narrow-leaved ash tree seedlings (forest
office Morovic, locality Vinicna) in the early spring of 2015, after the
catastrophic floods in May 2014, revealed presence of large dark necrotic
areas on 1-2 year old sprouts. The isola?tion of the fungal pathogen was
done by standard phytopathological protocols. Three repre?sentative isolates
(K41, K42 and K78) were preliminary detected and purified by a single-spore
technique for further morphological, molecular analyses and pathogenicity
testing. Morphological characteristics classified the isolates as Fusarium
tricinctum. Tested isolates on narrow leaved ash sprouts caused reddish
brown elongated necrotic lesions averaged 20.1 mm. Two marker genes,
translation elongation factor 1-alpha (TEF1-?) and internal transcribed
spacer (ITS1), were used in this study. Using the Basic Local Alignment
Search Tool (BLAST) searching engine, nucleotide sequences were compared to
all related sequences. Alignement score resulted in 98.9% identities with F.
tricinctum for isolate K78, while isolates K41 and K42 showed 94.1% and
94.3% identities with F. tricinctum complex respectively. To the best of our
knowledge, this is the first report of F. tricinctum pathogen infection on
flood stressed narrow-leaved ash trees in Serbia.

Authors: Steiner M. , Franco D. , Steiner Nieto P.
Published: September 2022

During the pandemic caused by the Coronavirus (Covid-19), Machine Learning (ML) techniques can be used, among other alternatives, to detect the virus in its early stages, which would aid a fast recovery and help to ease the pressure on healthcare systems. In this study, we present a Systematic Literature Review (SLR) and a Bibliometric Analysis of ML technique applications in the Covid-19 pandemic, from January 2020 to June 2021, identifying possible unexplored gaps. In the SLR, the 117 most cited papers published during the period were analyzed and divided into four categories: 22 articles that analyzed the problem of the disease using ML techniques in an X-Ray (XR) analysis and Computed Tomography (CT) of the lungs of infected patients; 13 articles that studied the problem by addressing social network tools using ML techniques; 44 articles directly used ML techniques in forecasting problems; and 38 articles that applied ML techniques for general issues regarding the disease. The gap identified in the literature had to do with the use of ML techniques when analyzing the relationship between the human genotype and susceptibility to Covid-19 or the severity of the infection, a subject that has begun to be explored in the scientific community.

Abstract: Improving Skills and Thematic Learning Outcomes in Fractional Materials Through the Application of the Ctl (Contextual Teaching and Learning) Approach for Class III Students of Public Elementary School Peunyareng, Academic Year 2021/2022. This study aims to improve the Skills and Learning Outcomes of Fractions in Thematic Learning of Grade III students of SD Negeri Perumnas Peunyareng, Academic Year 2021/2022. The model used in this classroom action research is the CTL (Contextual Teaching and Learning) approach. The subjects of this classroom action research are students III of SD Negeri Perumnas Peunyareng, Academic Year 2021/2022. The number of students is 15 students with 10 male students and 5 female students. This classroom action research is carried out in the 2021/2022 Academic Year. This classroom action research is carried out over a period of 3 months, from February 2022 to April 2022 in the even semester. The methodology of this research is classroom action research consisting of two cycles and each cycle consists of two meetings. Each cycle consists of planning, implementing, observing and reflecting. The research procedure consisted of pre research, planning cycle one, implementing cycle one action, observing cycle one, reflecting on cycle one, planning cycle two, implementing cycle two, observing cycle two and reflecting on cycle two. The data collection technique is collecting test scores which are carried out at the end of each learning cycle in each cycle using a question instrument (written test). Observation data is done by looking at the students' skills in the learning process. Data were analyzed by means of percentage statistics. The results showed that there was an increase in the mastery of student learning outcomes from 34.78% in the pre-study to 60.86% in the first cycle and increased to 78.26% in the second cycle. Student learning skills have increased from moderate to good category and good category to very good category. The CTL (Contextual Teaching and Learning) approach can improve skills and thematic learning outcomes in fractions of third grade students at SD Negeri Perumnas Peunyareng, Academic Year 2021/2022
Pit building ant-lion larvae effect to the distribution of the substrate particles in their microhabitats
Authors: Ábrahám Levente
Published: September 2022

The distribution of the size of the substrate particles in and around the pits of the pit-building antlion larvae was examined at two different types of microhabitats (open and protected). Samples of substrate were taken from the side of the pits, from the edges of the pits and from 3 cm and 10 cm away from the edges of the pit. The size of the substrate particles taken 10 cm away from the edge is considered to be characteristic for the microhabitat. The samplings consisted of different quality of substrates such as sand, loess, clay and they were taken at all three larvae stages. The samples were divided into fractions by a sieve series and the distribution of the weight percentage of the granulation was analyzed. In order to compare the samples the cluster analysis and statistical tests were used. The preference calculations were performed with Ivlev's index of preference (Ei minimum -1; Ei maximum +1). In this respect the distribution of sandy area in the Carpathian Basin is in correspondence with the distribution of the pit-building ant-lion larvae living in open habitats. The preference of the ant-lion larvae living in protected habitat does not depend on the bedrock. The investigation proved that the substrate has particular spatial distribution in the pits and their environment (microhabitat). While building and repairing the pit, the larvae gather the fine particles in the pit and throw the bigger particles further out from the pit. The spatial distribution of the particle size of the substrate can be actively influenced by the chitin bristles and teeth of the mandibles and head of the larvae. Statistical analysis has proved that the particle size preference does not depend on the development stage of the larvae, it is not species dependent and it does not depend on the quality of the substrate as well. The preferred particle size of the pit-building ant-lion larvae was determined by the physical characteristics (particle size, to what extent they were cemented) of the substrate (sand, loess, clay) which is typical of the habitat. The present and the earlier studies suggest that Euroleon nostras, and very likely other pit-building species living in protected microhabitat, chose their habitats providing less food besides optimal particle size and thermal conditions. On the other hand, the species occurring in open habitats such as Myrmeleon bore, live in habitats with bigger food supply but with extreme thermal conditions and coarser particle size.

A Drávamenti-síkság Nanocyperion jellegű fajainak vörös listája
Authors: Csiky János , Oláh Emőke
Published: September 2022

The systematic reveal of the Drava Plain's flora has been started in the last years. In the course of these investigations the description of the Nanocyperion flora and vegetation was completed from the area, which has been shaped by human activity (e.g. segetal fields with inland water, meadows, pastures, ponds, wayside pools). This paper presents distribution of 29 Nanocyperion like species of vascular plants in the cartogramme grid system developed by NIKFELD (1971) and adopted for Hungary by KIRÁLY & HORVÁTH (2000). Some of the plants (8) are protected. Alisma gramineum and Scirpus radicans are regionally extinct (RE) species (their last observation are older than 40 years). The risk categories (RE, CR, EN, VU, NT, LC, DD) follow the new IUCN proposal (IUCN 2001). As rarity, population dynamics are scale dependent marks of a species, the IUCN risk categories were considered according to the spatial scale of the Hungarian flora mapping raster grid system (Király 2005) in this work (1 grid = 1 locality). The species under legal protection were indicated in accordance with the last valid Hungarian list (13/2001. (V. 9.) KöM г.).

In view of the fragile ecological health of the Futian mangrove wetland ecosystem, an index system for evaluating ecosystem health of the Futian mangrove wetland was established based on the ‘pressure-state-response’ (PSR) model. The ecosystem health evaluation of the Futian mangrove wetland was carried out based on three aspects: pressure subsystem, state subsystem and response subsystem. Analytical hierarchy process (AHP) was used to determine the index weight. The index system is established and evaluated by the comprehensive index method. The results showed that the ecosystem health index of the Futian mangrove wetland was 0.25262. According to ecosystem health assessment criteria, it falls into the ‘poor’ range. Based on our assessment, we consider that the structure and function of the Futian mangrove wetland ecosystem are degraded, that there has been a decline in biodiversity and that the prevailing environmental problems are serious. The results of this study can provide an effective scientific basis for the management of the Futian mangrove wetland ecosystem.
