Valuation of health benefits of green-blue areas for the purpose of ecosystem accounting: a pilot in Flanders, Belgium
Authors: De Nocker Leo , Liekens Inge , Beckx Carolien , Broekx Steven
Published: July 2022

In recent years, a vast amount of scientific literature has highlighted the benefits of nearby greenspace for physical and mental health, but the large variation in scope, methods and indicators used in these studies hampers the assessment of these benefits in the context of natural capital accounting. To our knowledge, this paper is one of the first studies to quantify and value these benefits in the context of natural capital accounting. A method was developed and applied to the Flemish region in Belgium for 2013 and 2016. 

The physical supply and use accounts for health are based on a set of selected dose-effect relations that quantify the impact of the availability of greenspace on 7 specific indicators for physical and mental health, including mortality, cardio-vascular diseases, diabetes and depression. The indicator for green-blue areas is the % of green-blue areas in total land use, calculated for 0.5, 1 and 3 km radius from the residence, based on detailed land-use maps (10m x 10m) for Flanders, Belgium. The base-line data for mortality and illness are average data for the Flemish region. These health impacts are weighted using Daly's (disability-adjusted life years) and aggregated. The total health benefits due to the availability of green-blue areas for the total Flemish population was estimated almost 85.000 DALY’s. This is 27% of the estimated total burden of disease in 2016 for the 7 selected diseases. 

The monetary accounts include assessments of avoided costs of illness (e.g. hospitalisation costs) and avoided absenteeism and productivity loss. In addition, we valued the years of life lost due to cardio vascular mortality based on simulated exchange values. The total monetary benefits amount to 464 Euro per inhabitant per year or 3 billion Euro per year for Flanders. This corresponds to 1.3% of the GDP, which reflects the importance of these benefits. Productivity gains and avoided costs of illness account for respectively 52 % and 36% of these costs. 

The methodology is incomplete as not all health indicators are covered, mainly due to a lack of dose-effect relations. The research priority for potential users of the accounts is a better indicator for contact with greenspace that does differentiate between ecosystems, their quality, accessibility or their use. This requires more systematic health impact studies that take these elements into account, as well as more systematic data on the daily use of greenspace by citizens. In the meantime,  an additional set of condition accounts on these elements can be used, especially to follow changes in quality and use of green blue areas over time.
Phylogenetic, ecological and morphological characteristics reveal two new spider-associated genera in Clavicipitaceae
Authors: Chen Wan-Hao , Liang Jian-Dong , Ren Xiu-Xiu , Zhao Jie-Hong , Han Yan-Feng , Liang Zong-Qi
Published: July 2022

Clavicipitaceous fungi are pathogenic to scale insects, white flies and other insect orders. However, a few species are spider-associated. Two new genera from China, Neoaraneomyces and Pseudometarhizium, are described based on phylogenetic, ecological and morphological characteristics. Two spider-associated species, Neoaraneomyces araneicola, Pseudometarhizium araneogenum, and an insect-associated species Pseudometarhizium lepidopterorum are included. The morphological characteristics of paecilomyces-like conidiogenous structures, present in many insect/spiders associated species make species-level identifications difficult. A phylogenetic analysis of the combined dataset (ITS, LSU, RPB2 and TEF), placed the two new genera in Clavicipitaceae. The new spider-associated species may be the result of convergent evolution to adapt to the ecological environment and may have undergone host jumping or altered their nutritional preferences.

The impact of research-oriented collaborative inquiry learning on pre-service teachers' scientific process skills and scientific attitudes
Authors: Irwanto Irwanto
Published: July 2022

In the past decade, scientific process skills and scientific attitudes are widely regarded as essential factors influencing students’ achievement and their future career choices. Unfortunately, previous literature found that students’ scientific skills and attitudes tend to be unsatisfactory. Thus, cultivating students’ skills and attitudes is seen as a fundamental goal in science education. This research sought to promote scientific process skills and scientific attitudes of pre-service chemistry teachers using REORCILEA (Research-Oriented Collaborative Inquiry Learning). In this quasi-experimental research, a one-group pretest and posttest design was utilized. A total of 50 pre-service teachers (6 males and 44 females) at a medium-sized public university in Indonesia were recruited for this study. In order to gather data, the Scientific Process Skills Observation Checklist (SPSOC) and the Scientific Attitude Survey (SAS) were administered before and after the intervention. The data obtained in this study were analyzed through a paired-samples t-test and Cohen’s d. The results showed a significant increase from pretest to posttest in scientific process skills and scientific attitude scores during treatment, each with a high effect size. It can be summarized that REORCILEA is effective in fostering scientific skills and positive attitudes of pre-service chemistry teachers to a satisfactory level. It is recommended for educators to apply REORCILEA to other college chemistry courses to improve their performance.
CO2 capture and conversion: A homemade experimental approach

Published: July 2022

During the SARS-2-Covid pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students´ homes. Thanks to this approach students were able to perform ~25 experiments during each one of the Fall 2020 and Spring 2021 semesters in an elective Electrochemistry and Corrosion course offered to Chemical Engineering undergraduates. In addition to performing traditional experiments, students were encouraged to design some of their own and have the entire group reproduce them. One of such student-designed experiments involved the capture of CO2 and its reduction with a readily available active metal (i.e., Al foil) in aqueous media to generate potentially useful products. The highly negative standard potential of Al is exploited for the reduction of lab-generated CO2, and the products are chemically tested. Al as a foil has been reported to be electrochemically inactive for carbon dioxide reduction. However, encouraged by an earlier report of the reduction of CO2 to CO, the Al surface is activated in the present experiment by removal of its natural oxide layer with a solution of CuCl2 produced in an electrochemical cell. This procedure enables Al to react with CO2 and yield useful chemistry. This experiment turned to be a discovery trip. The detailed procedure is discussed here, as well as the teaching methodology, grading scheme, and student outcomes.

Published: July 2022

The case study-based module on chemical thermodynamics course (ideal and real gases) was developed to fulfill the needs of undergraduate students in online learning during the COVID-19 pandemic. The purpose of this study was to test feasibility of case study-based module. The case study-based module refers to the 4D model (define, design, develop, and disseminate) by integrating the one group pretest-posttest design at the develop stage. The feasibility of the module was measured through validity, practicality and effectiveness using validation sheet, evaluation test sheet and questionnaire sheet. Data were analyzed descriptively, quantitatively (Wilcoxon Signed Rank Test) and qualitatively. The case study-based module was suitable for one of learning tools, which was proven by the findings that 1) meets valid and reliable criteria, 2) meets practical criteria with support for general achievements students’ very positive response to the aspects of module (construction, material, motivation and case study), and 3) meets the effective criteria by increasing the average score pretest-posttest in medium category which contains the cognitive level of analyze-C4, evaluate-C5, and create-C6. The implication of development case study-based module can facilitate students in online learning during the COVID-19 pandemic so that they will successfully reach the course learning outcomes of Chemical Thermodynamics, which includes mastery of knowledge about main principles of thermodynamics, ability to solve science and technology problems, ability to use information and communication technology based learning resources, make decisions based on the relationship of concepts with laboratory activities, and practice responsibility.
A discrete choice model for partially ordered alternatives
Authors: Aristodemou Eleni , Rosen Adam M.
Published: July 2022

In this paper, we analyze a discrete choice model for partially ordered alternatives. The alternatives are differentiated along two dimensions: the first an unordered “horizontal” dimension, and the second an ordered “vertical” dimension. The model can be used in circumstances in which individuals choose among products of different brands, wherein each brand offers an ordered choice menu, for example, by offering products of varying quality. The unordered–ordered nature of the discrete choice problem is used to characterize the identified set of model parameters. Following an initial nonparametric analysis that relies on shape restrictions inherent in the ordered dimension of the problem, we then provide a specialized analysis for parametric specifications that generalize common ordered choice models. We characterize conditional choice probabilities as a function of model primitives with particular analysis focusing on cases in which unobservable taste for quality of each brand offering is multivariate normally distributed. We provide explicit formulae used for estimation and inference via maximum likelihood, and we consider inference based on Wald and quasi‐likelihood ratio statistics, the latter of which can be robust to a possible lack of point identification. An empirical illustration is conducted using data on razor blade purchases in which each brand has product offerings vertically differentiated by quality.
The importance of hiring frictions in business cycles
Authors: Faccini Renato , Yashiv Eran
Published: July 2022

Hiring is a costly activity reflecting firms' investment in their workers. Microdata show that hiring costs involve production disruption. Thus, cyclical fluctuations in the value of output, induced by price frictions, have consequences for the optimal allocation of hiring activities. We outline a mechanism based on cyclical markup fluctuations, placing emphasis on hiring frictions interacting with price frictions. This mechanism generates strong propagation and amplification of all key macroeconomic variables in response to technology shocks and mutes the traditional transmission of monetary policy shocks. A local projection analysis of aggregate U.S. data shows that the empirical results, including the cyclicality of markups, are consistent with the model's impulse response functions.
Choice, deferral, and consistency
Authors: Costa-Gomes Miguel A. , Cueva Carlos , Gerasimou Georgios , Tejišcák Matúš
Published: July 2022

We report on two novel choice experiments with real goods where subjects in one treatment are forced to choose, as is the norm in economic experiments, while in the other they are not but can instead incur a small cost to defer choice. Using a variety of measures, we find that the active choices (i.e., those that exclude the deferral outside option) of subjects in the nonforced‐choice treatment are generally more consistent. We also find that the combined deferral and active‐choice behavior of subjects in that treatment is explained better by a model of dominant choice with incomplete preferences than it is by rational choice. Our results suggest that nonforced‐choice experiments and models can be helpful in separating people's rational, hesitant/not‐yet‐rational and genuinely irrational behavior, and can potentially offer important new insights in revealed preference analysis.

Hellenistic bell-shaped situlae with ivy leaves
Authors: Blečić Kavur Martina
Published: July 2022

Situla art, as a specific visual and semantic synthesis, connected numerous culturally different societies of the prehistoric and historic Iron Age of Europe. Situlae themselves, which gave the name to this art phenomenon, were not only carriers of artistic expression and symbolic narrative, but also reflected a cognitive maturity and sublimation of society as an accepted emblem of the way individual aristocracies represented their status. The area of the northern Adriatic boasts examples of the Early Iron Age situla art and the later, ‘Hellenistic’ situlae. The starting point of the present research are the fragments of Hellenistic bell-shaped situlae decorated with ivy leaves from Rijeka, which are analyzed typologically, as well as stylistically and iconographically in comparison with all the hitherto known situlae of this type. The article brings an updated list of bell-shaped situlae, presents arguments for their more precise chronological position, their typological and technological division into two major groups with variants and the related different toreutic centres of production. The distribution of Hellenistic bell-shaped situlae with ivy leaves shows that the eastern Adriatic coast and its hinterland were a place of contact between Macedonian and Etruscan luxury toreutic products.
Cast bronze vessels in the northern Adriatic region (c. 600 AD).
Authors: Pinar Gil Joan
Published: July 2022

Although cast bronze vessels of the 6th–8th centuries are not recorded in particularly large numbers, their production and distribution provide a representative sample of the general economic trends and of the evolution of trade networks in the post-Roman Mediterranean. The geographical dissemination of these objects shows that at the turn of the 6th century, the northern Adriatic region became the main gateway of ‘eastern-style’ vessels into Central Europe and the Western Mediterranean. The region was thus replacing the Rome area as the main Western hub for redistributing this type of object. From the northern Adriatic area, several types of vessels were distributed both over land along the Po and Rhine valleys and through maritime routes connecting the Adriatic with Carthage and the Spanish Levant. The intrinsic features and the depositional contexts of the post-Roman cast bronze vessels suggest that they were manufactured according to different quality standards, which targeted different social milieus. Furthermore, mapping the distribution of the different quality standards reveals that each of them might have been distributed by different networks of merchants and unveils the impact of transportation costs on the final price of these products.

Ramón Menéndez Pidal y el problema del paradigma científico. Positivismo y tendencia humboldtiana
Authors: Santano Moren Julián
Published: July 2022

El artículo se plantea el paradigma científico en el que ha sido encuadrada la obra de Ramón Menéndez Pidal. La ausencia de una reflexión teórica explícita en la obra pidaliana ha dificultado su definición y ha llevado a algunos autores a enmarcarla en el positivismo y el paradigma schleicheriano. La realidad, sin embargo, es mucho más matizada. El trabajo distingue en la obra pidaliana entre teoría y práctica y concluye que las concepciones teóricas en la obra de Menéndez Pidal responden a la tendencia humboldtiana, en concreto la Völkerpsychologie, y no al paradigma positivista schleicheriano, del que sí toma el rigor científico.

Coronavirus disease 2019 is a severe acute respiratory syndrome, and wearing a mask is an important preventive measure. However, long-term use can cause “maskne,” or mask-induced acne. This study evaluated the prevalence, clinical characteristics, and severity of mask-induced acne and its effect on pre-existing dermatosis using an online questionnaire. The questionnaire comprised 15 questions on six primary topics: demographic data, type of face mask, dermatological symptoms after using a mask, preexisting dermatological conditions, the duration of use, and the effects of mask use on existing dermatological conditions. We included 1,025 participants; 48.6 % had dermatological symptoms after using masks. The most common symptoms were red papules (33.8 %) and itching (27.2 %). Individuals who wore masks for more than four hours daily experienced more dermatological symptoms, for example, healthcare providers, who had a higher risk of mask-related dermatosis than participants with other occupations. Moreover, masks significantly increased the severity of rosacea, contact dermatitis, and seborrheic dermatitis. These results suggest that board-certified dermatologists should assess patients in larger-scale studies to determine adequate management strategies.
Creative Resource Utilization in Rural Settings

Published: July 2022

Cholecystostomy tubes are an established treatment option for patients with acute cholecystitis who are considered high risk for cholecystectomy. This is typically done as an interventional radiology procedure through a pigtail catheter inserted percutaneously. A 63-year-old diabetic male presented to our remote Emergency Department in rural North-Western Victoria (Modified Monash Model 4), with severe, stabbing epigastric pain. Despite normal bloods and imaging, the patient became progressively unwell necessitating a diagnostic laparoscopy and open conversion, which revealed acute acalculous gangrenous cholecystitis. A cholecystectomy was attempted and subsequently abandoned as safe dissection within Calot's triangle, without damaging biliary structures, was not possible. Based on the limited available resources at our rural center, a urinary (Foley) catheter was placed in the gallbladder and Hartmann's pouch sutured around it to act as a temporizng cholecystostomy tube while awaiting transfer to a tertiary center. The Foley catheter was removed after 6 weeks with no further intervention required with the patient making a full recovery. Compared to patients in urban areas, rural residents are more likely to experience health-care disadvantages, including increased likelihood to undergo procedures by specialists operating outside of their scope of practice and higher rates of emergency-related intensive care unit admissions. Despite this, and regardless of acuity, specialist availability, or resource distribution, patients will continue to present to rural services with serious medical issues. In such situations and in resource-poor settings, creative solutions are required to temporize ill patients, as we have reported, and represent an important facet of care in a rural setting.

Published: July 2022

The essential oil from aerial parts of Pituranthos scoparius obtained by hydrodistillation was analyzed by GC, GC/MS and 13C NMR and evaluated for antimicrobial and antioxidant activities. The yields were showed a very high variability ranging from 0.16 to 0.99%. Sixty two components were identified and the results indicated that the essential oil was rich in hydrocarbons monoterpenes and phenylpropanoid compounds. 6-Methoxyelemicine (0.1- 47.0%), sabinene (1.4-35.5%), limonene (0.6-24.0%), myristicine (0.2-18.9%), α-pinene (3.1- 14.7%) and dill apiole (0.0-10.6%) were the major compounds. The essential oils were tested against Staphylococcus aureus, Bacillus cereus, Escherichia coli, Klebsiella pneumonia, Candida albicans, Fusarium oxysporum, Aspergillus fumigatus and Aspergillus flavus and the minimum inhibitory concentration was determined. The tested oils have been shown to possess inhibitory action in the range from 2 to 3 µL/mL against Aspergillus fumigatus, Staphylococcus aureus and Candida albicans. The antimicrobial activity of essential oil from P. Scoparius well be due probably to the presence of synergy between myristicine and terpinen-4-ol. The antioxidant activity was evaluated through DPPH assay. All samples exhibited weak scavenging activity against DPPH, compared to standard antioxidant tested. Essential oil with IC50 of the order of 23.65±0.77 and 25.95±2.13 mg/mL could be attributed probably to the presence of limonene and germacrene D in larger amounts.

In the present paper, we are interested, for the first time, to separate and identify two glycosyl the flavones from Sedum villosum L, family Crassulaceae collected in the flowering phase in Lakhdar Oued, village of Tlemcen (Algeria). The crude methanolic extract of the flowers part was fractionated on column chromatography, and eluted with dichloromethane/methanol each time with increasing polarity of methanol; 24 fractions were separated. One of these fractions named F16 showed more antioxidant activity to scavenge DPPH free radical with percentage inhibition of 94.849 %. F16 was separated by thin-layer chromatography (TLC) to give 10 compounds. We were chosen the sub-fractions F16.8, which has antioxidative activity of 77.02 %, provided two major molecules of glycosyl the flavones, analysed by ultra-highperformance liquid chromatography coupled to mass spectrometry (UHPLC-DAD-HRSM). Compound 1 was identified as 7, 3'-dihydroxyflavone-5-O-dihexosyl-4'-O-deoxyhexose and compound 2 was 7, 3'-dihydroxyflavone-5-O-hexose- 4'-O-deoxyhexose.

A survey is carried out on 148 diabetic patients from rural Fellaoucene, Tlemcen Province (North-Western Algeria). The main interest of this study is to determine the frequency of diabetic patients using medicinal plants with their conventional medication to relieve their diabetes mellitus and to compare their serum biochemical parameters with patients do not use these plants in combination with drugs. A questionnaire is used to collect information about patients (age, sex), diabetes (duration, type, treatments, and complications), antidiabetic plants use (vernacular, scientific names) and variation of some serum biochemical parameters (glycemia, triglyceride, cholesterol, urea, creatinine, glycated hemoglobin (HbA1c)). 72% of diabetic patients are type 2 diabetes mellitus and 77% of them are women with a mean age of 53 years. More than 26% of the cases are suffering from diabetes for more than 10 years. 96% of the patients are affected by at least one chronic complication. The results show that 21% of diabetics use medicinal plants without any significant effects on the balance of the biochemical parameters tested. We notice a slight increase in glycemia (1.39±0.48 g/l) and HbA1c (7.27±0.69 %) of both populations when compared to the values recommended by WHO (1.26 g/l and 6.5%, respectively). The medicinal plants still have a place in the treatment of diabetes mellitus in the rural region of Fellaoucene, Tlemcen (Algeria)

Regardless of the associated pharmacological treatment modality, hygienic-dietary measures, focusing on lifestyle modification (diet and physical activity), represent the basis of the management of type 1 and type 2 diabetes. In order to ensure that these dietary measures are effective and long lasting, their implementation and follow-up require guidance. This work focuses on nutrition coaching based on a low glycemic index (GI) diet proposed to type 2 diabetics with the aim of reducing postprandial glycemia in the direction of a better balance to help prevent micro and macro-vascular complications. This method is easy to follow and does not require high restrictions, it allowed us to significantly lower glycated hemoglobin (HbA1c) by 0.92% after a 12-week follow-up (P < 0.05). However, the control diabetic patients who did not benefit from the coaching did not show any significant difference before and after the 12-week experiment.

Caves are laboratories for many disciplines that work in natural sciences including mineralogy, biology, hydrogeology, and archaeology. In this study, bi-monthly samplings were carried out from three sampling locations within and around the Güvercinkaya Cave, a high-altitude cave located in northwestern Turkey, to evaluate the hydrochemical and microbiological properties and the aquatic macroinvertebrates of the cave stream. Some parameters of the water including pH, electrical conductivity, temperature, oxidation-reduction potential, and dissolved oxygen were measured in-situ, while elemental (70 in total) and ionic composition of water were analyzed in the laboratory. Microbiological analyses of the cave stream were examined through analyses of total bacteria, total coliforms, fecal coliforms, fecal Streptococcus, and Escherichia coli. According to the Piper diagram of hydrochemical data, the cave stream had mainly Ca-Mg-HCO3 character, on the other hand, the Schoeller diagram indicated a common water source in Güvercinkaya cave due to the similar components of the main ionic components of the water. As a result of microbiological analysis, fecal contamination was determined, indicating active wildlife in the cave. Additionally, several aquatic macroinvertebrates taxa, Rhynchelmis limosella, Dugesia sp., Gammarus uludagi which have non-troglobiont character were found in the cave stream. Rhynchelmis limosella detected in this study is the first record for the Turkish fauna.

In the frame of a case study, the data were gathered from in-depth interviews and a set of questions. The findings revealed that TEs had sufficient research knowledge as they were able to identify good quality of research, read relevant reading research, and signified the importance of research as part of their professional identity. Completion of other tasks, lack of research motivation and collegiality, shortage of research skills and competencies including how to read academic articles due to vocabulary and sentence construction hindered them from conducting research. The workshop has facilitated the TEs autonomy, research skills and competencies, research collaboration, and goal-orientation. The PD program strengthened their research motivation and engagement that scaffold positive insights into their self-research awareness. Moreover, all TEs were able to complete their papers and submit them to reputable journals.

В настоящее время мировое сообщество серьезно обеспокоено быстрым и непредсказуемым ростом применения синтетической пищевой упаковки, что приводит к постоянному накоплению биологически не разлагаемых отходов, технология утилизации которых сложна и дорогостояща. Это обусловливает рациональность замены таких упаковочных материалов биоразлагаемыми съедобными пленками, в частности, на базе пектиновых веществ природного происхождения, которые являются природными структурообразователями, полученными из неутилизируемых отходов при переработке растительного сырья. В этом аспекте интересно использование корки арбузов, существенная часть урожая которых не доходит до потребителя по причине ее недостаточной кондиции или просто (около 150 тыс. т) остается на полях неубранной. Причем в арбузной корке содержится до 13,4 % пектиновых веществ, 8,1 % которых являются протопектином, обусловливающем прочностные параметры ягодной ткани. Для решения поставленных в работе задач, в частности, выбора рациональных режимных параметров и моделирования сушки, проведено исследование ее статики путем определения гигроскопических характеристик и термодинамических закономерностей влагосорбции пектиновым гелем из корки арбуза, что позволило определить энергию связи влаги с сухим остатком и, как следствие, в полной мере оценить энергозатраты при процедуре его обезвоживания, а также рекомендовать конечную рациональную влажность готовой продукции в итоге процесса сушки для ее долговременной сохранности при использовании и хранении и, кроме того, определить целесообразные параметры окружающей среды, которые необходимо поддерживать в торговых, производственных и складских помещениях.

Published: July 2022

Прогнозируемый рост производства рыбной продукции повлечет за собой увеличение объемов неиспользуемых отходов, белковая часть которых в значительной степени представлена коллагеном. Ожидается двукратный рост общемирового рынка этого белка за 10 лет в финансовом выражении, при этом морской коллаген обладает преимуществом по сравнению с коллагеном наземных животных вследствие его низкой иммуногенности, отсутствия связан-ных зоонозных заболеваний и религиозных ограничений на его потребление, а также низкой себестоимости. В результате сравнения наиболее широко произво-димого коллагена I типа с полученным нами коллагеном V типа выдвинуто пред-положение об уникальных характеристиках надмолекулярной структуры послед-него, обусловленных цикличностью развития плацентарных тканей. Приведен обзор различных технологий фибриллообразующих и сетеобразующих морских коллагенов, которые не охватывают переработку вторичного плацентарного сы-рья. Предложена обобщенная функциональная схема получения растворимого коллагена, при конкретизации которой для частной технологии следует учитывать физико-химические особенности сырья и принадлежность извлекаемого белка к конкретному типу. Рассмотрены существующие направления использования коллагена в косметической промышленности, обусловленные его биосовместимостью, биоразлагаемостью, биомиметическими и кровоостанавливающими свойствами. Среди спектра назначения возможных косметических препаратов отмечены антивозрастная защита, смягчение и увеличение эластичности кожных покровов, анальгезирующее и регенерирующее действие, защита от УФ-излучения, восстановление структуры волос и укрепление ногтевой пластины. Предложены образцы товарных форм косметических средств на основе полученного нами морского плацентарного коллагена и иных нативных компонентов икры, извлекаемых из вторичного сырья. После применения изготовленных нами косметических препаратов у добровольцев отсутствовали какие-либо отрицательные эффекты. Спрогнозирован синергетический эффект при совместном использовании колла-гена I и V типов. Отмечен экологический аспект производства морского плацен-тарного коллагена.

O estudo teve como objetivo modelar por redes neurais artificiais perceptron multicamadas (RNA-MLP) a evapotranspiração de referência , em função das variáveis climáticas para o município de Ariquemes – RO. Para a caracterização das séries temporais das temperaturas do ar (médias, máximas e mínimas), umidade do ar e precipitação pluviométrica foram utilizados os dados disponíveis no Instituto Nacional de Meteorologia - INMET, obtidos na estação meteorológica automática de Ariquemes/RO, no período de janeiro de 2011 até dezembro de 2013. Os dados da evapotranspiração utilizados foram calculados seguindo o modelo Penman-Monteith-FAO. Dentre os resultados, observou-se que a utilização de modelos RNA-MLP com variáveis de mais simples obtenção, entre elas a precipitação chuvosa, temperatura do ar e umidade foram satisfatórias para estimar a , pois foram consideradas como “muito boas” no índice de concordância.
Perspectives of the rural communities of Impendle, Bulwer, and Kokstad in South Africa using ethnomedicinal plants to cure flu and associated symptoms in the advent of COVID-19
Authors: Zondi Lungile Prudence , Ehaine Stanley
Published: July 2022

The contribution of ethnomedical research in the advent of infectious illness is not new. Ethnomedicinal plants have historically embodiment of wisdom from the ancestors and play a significant role in treating various human disorders. This study embodies qualitative research methods as well as the Social Constructivist Theory to understand how the rural communities (Impendle, Bulwer and Kokstad), located within the geographical landscape of South Africa use ethnomedicinal plants to cure flu and other associated symptoms in the advent of COVID-19. Through telephonic interviews, twenty (20) research participants were recruited using the snowballing-chain referral sampling technique. Research participants contributed by noting that rural communities/cultures have a rich knowledge of ethnomedicinal plants that they have used for decades to treat flu symptoms and even cure people suffering from flu. This paper strongly recognises that people’s voices in rural communities are important in understanding their illness or disease experience and how they ethnomedical respond to them. Data analysis revealed African activism towards the COVID-19 impact on rural communities. This paper thus recognises indigenous knowledge as ancestral learning, as the source of social, domestic wisdom as well as a guide on the use of ethnomedicinal plants/ethnomedicine. Ethnomedicinal plants remain the wealth of rural communities as they are able to demonstrate their agency and resilience when confronted by different illnesses. This is their contribution to the decolonial agenda which seeks to recognize the wealth of ethnomedical plants against the hegemonic pragmatism of biomedicine. This paper then proposes that discussed ethnomedicinal plants should be acknowledged in South Africa as well as in Southern Africa as their indigenous wealth and should be vetted as traditional remedies that people have used to cure flu and associated symptoms. This recognition will thus achieve decolonial thinking of African indigenous/ethnomedicinal plants.
