El cultivo de Oreochromis spp., representa una base económica en diferentes países debido a que la especie muestra diversos grados de tolerancia a factores fisicoquímicos y un rápido crecimiento. En esta investigación se evaluó el efecto de la inclusión de Lens culinaris en dietas de alevines de tilapia. Los alevines tuvieron pesos y tallas similares de 1,20 g ± 0,01 y 2,9 cm ± 0,01, respectivamente. Los alimentos fueron racionados cuatro veces al día donde se determinó el efecto del crecimiento mediante diferentes niveles de sustituciones (0, 80, 50 y 20 %) de harina de lenteja. Los índices productivos analizados fueron: tasa de crecimiento, tasa de eficiencia, factor de condición y conversión alimenticia. Se observaron diferencias significativas entre las dietas en cuanto al peso, talla y tasa de crecimiento específico, siendo el control eficiente con respecto a los demás tratamientos. De acuerdo, a este estudio L. culinaris puede ser incluida hasta un 20 % para la alimentación en alevines de Oreochromis spp sin afectar los parámetros productivos.

En la fisiología de los peces triploides, falta información sobre sus respuestas moleculares bajo estrés y cómo cuantificar los niveles o la intensidad del estrés. Por lo tanto, los objetivos de este ensayo fueron evaluar el patrón de HSP70 en las branquias, el corazón y los músculos de truchas arco iris diploides y triploides no estresadas, y en las células sanguíneas después de la exposición al estrés por calor para evaluar sus niveles de estrés. Se observó una detección inmunohistoquímica de HSP70 similar en las muestras de branquias, corazón y músculos en ambas ploidías. Sin embargo, la expresión de HSP70 en sangre varió entre ploidías durante el tiempo experimental. Las truchas diploides de control y estresadas mostraron niveles análogos de HSP70, pero las truchas triploides estresadas por calor mostraron niveles más bajos de HSP70 durante todo el experimento con diferencias observadas después de 12 h y 24 h. Se esperaba una mayor expresión de HSP70 en ambas ploidías una vez que esta proteína protege a las células contra una amplia gama de agentes perturbadores. Evidencias recientes mostraron que los peces triploides tienen una menor expresión génica y este hecho debe ser explorado en futuras investigaciones en truchas arcoíris. En conclusión, las comparaciones a lo largo del tiempo entre los niveles diploides y triploides de HSP70 en truchas podrían usarse en la evaluación del estrés y de bienestar.

Published: July 2022

La camaronicultura es una actividad en constante crecimiento, lo que ha llevado al deterioro de los ecosistemas por la deposición de efluentes que impactan al medio ambiente, generando no solo daños a los ecosistemas sino también a la misma calidad del agua que ingresa al cultivo. Esta investigación busca evaluar la eficiencia de consorcios microbianos autóctonos (in vitro) en la biorremediación del efluente de una finca camaronera ubicada en el sector Cabello Manabí, Ecuador. Para ello, se analizaron los parámetros: fosfatos, amonio, nitritos, nitratos, sólidos en suspensión, oxígeno disuelto, temperatura, pH, DBO5 y coliformes totales. Se utilizó un diseño completamente aleatorio con un factor y 4 niveles y se realizaron 4 tratamientos: consorcio bacteriano (T1) incluyendo la levadura Saccharomyces cerevisiae, consorcio de microalgas (T2), consorcio de hongos (T3) conformado por Trichoderma harzianum, S. cerevisiae, Lactobacillus acidophilus, Bacillus subtilis, Lactobacillus plantarum, y como (T4) un consorcio combinado de los tres tratamientos anteriores. Se observó una diferencia estadísticamente significativa en T2 con respecto a los demás tratamientos, pues debido a sus actividades metabólicas se logró la biorremediación de elementos como fosfatos, compuestos nitrogenados y coliformes totales, mientras que en los demás parámetros no se logró una mejora significativa. El proceso llevado a cabo por las microalgas permitió ajustar los parámetros analizados a criterios de calidad del agua para ser reutilizados en actividades agrícolas y ganaderas e incluso vertidos en cuerpos de agua dulce, concluyendo que la aplicación de microalgas autóctonas de la zona es útil para la biorremediación de los efluentes camaroneros de la localidad.

Published: July 2022

RESUMO O Parachromis dovii é um peixe carnívoro da América Central, o qual aceita facilmente rações formuladas desde o início da alimentação exógena; no entanto, seu crescimento larval é inferior ao obtido com alimentos vivos. Por esta razão, o efeito de diferentes combinações de fontes de proteína na dieta sobre o crescimento e a atividade de proteases digestivas alcalinas foi testado em larvas. As misturas proteicas de teste foram preparadas utilizando farinhas de peixe e subprodutos de aves em diferentes proporções (quatro dietas) e comparadas com um produto comercial (Artemia cysts Vitellus) e náuplios de Artemia, como controle. No final do ensaio, as larvas alimentadas com náuplios de Artemia apresentaram o melhor crescimento (taxa de crescimento específico (TCE): 17,6% PC/d). Por outro lado, a dieta Vitellus apresentou o menor TCE (12,0% peso corporal por dia (PC/d)) (LSD, P<0,05). Das fontes proteicas, o D3 (com o maior teor de farinha de subprodutos de aves) apresentou o pior TCE (12,6% PC/d), enquanto os demais tratamentos apresentaram valores similares (D1: 13,5%, D2: 13,2% e D4: 13,7% BW/d). A sobrevivência não foi afetada pelo tratamento (mais de 93%). A menor atividade de protease digestiva alcalina foi encontrada aos seis dias após a eclosão (DAH), e foi similar entre os tratamentos (P>0,05). A atividade da protease aumentou até 27 DAH, sendo maior nas larvas alimentadas com Artemia do que nos outros tratamentos (P<0,05). Não houve diferença na atividade da protease entre as dietas com mistura proteica e não houve diferença entre as dietas formuladas e a Vitellus, exceto aos 20 DAH (P<0,05).

Rapid integration into the host tissue is critical for long-term patency after small diameter tissue engineering vascular grafts (sdTEVGs) transplantation. Neural recognition may be required for host integration and functionalization of the graft. However, immune rejection and inflammation hinder nerve regeneration of sdTEVGs. Here, a CRISPR/dCas9-nanocarrier was used for targeted programming of regulatory T cells (Treg cells) in situ to promote nerve regeneration of sdTEVGs by preventing excessive inflammation. Treg cells and (C-C chemokine receptor) CCR2+ macrophage recruitment occurred after transplantation. The nanodelivery system upregulated ten eleven translocation (TET2) in Treg cells in vitro. Reprogrammed Treg cells upregulated anti-inflammatory cytokines and decreased the proportion of CCR2+ macrophages. IL-6 concentrations decreased to the levels required for nerve regeneration. Implantation of CRISPR/dCas9 nanodelivery system-modified sdTEVGs in rats resulted in Treg cell editing, control of excessive inflammation, and promoted nerve regeneration. After 3 months, nerve regeneration was similar to that observed in normal blood vessels; good immune homeostasis, consistency of hemodynamics, and matrix regeneration were observed. Neural recognition promotes further integration of the graft into the host, with unobstructed blood vessels without intimal hyperplasia. Our findings provide new insights into vascular implant functionalization by the host.
Reconstruction of a Global 9 km, 8-Day SMAP Surface Soil Moisture Dataset during 2015–2020 by Spatiotemporal Fusion

Published: July 2022

Soil moisture, a crucial property for Earth surface research, has been focused widely in various studies. The Soil Moisture Active Passive (SMAP) global products at 36 km and 9 km (called P36 and AP9 in this research) have been published from April 2015. However, the 9 km AP9 product was retrieved from the active radar and L-band passive radiometer and the active radar failed in July 2015. In this research, the virtual image pair-based spatiotemporal fusion model was coupled with a spatial weighting scheme (VIPSTF-SW) to simulate the 9 km AP9 data after failure of the active radar. The method makes full use of all the historical AP9 and P36 data available between April and July 2015. As a result, 8-day composited 9 km SMAP data at the global scale were produced from 2015 to 2020, by downscaling the corresponding 8-day composited P36 data. The available AP9 data and
in situ
reference data were used to validate the predicted 9 km data. Generally, the predicted 9 km SMAP data can provide more spatial details than P36 and are more accurate than the existing EP9 product. The VIPSTF-SW-predicted 9 km SMAP data are an accurate substitute for AP9 and will be made freely available to support research and applications in hydrology, climatology, ecology, and many other fields at the global scale.
Explaining Variations in Long-term Care Use and Expenditures Under the Public Long-term Care Insurance Systems: A Case Study Comparison of Korea and Japan
Authors: Kim Hongsoo , Yoon Nan-He , Hahn Youjin , Hashimoto Hideki
Published: July 2022

Background: Establishing universal coverage of formal long-term care (LTC) services is an urgent policy need for aging populations that requires efficient management of quality and financing. Although current variation in LTC service use between and within countries suggests the potential for improvement by efficient management, this topic remains underexamined. We aimed to identify the sources of variance in LTC use and expenditures through a unique cross-country comparison of Japan and South Korea, which have formal public LTC insurance (LTCI) schemes that are analogous but have unique operational and demographic structures. Methods: Taking administrative regions as the unit of analysis, we assembled data on the LTC utilization rate of people aged ≥65 years, and expenditures per recipient from 2013 to 2015 as the outcome variables. Explanatory variables included demand-related factors, such as regional demographic and economic conditions, and supply characteristics derived from existing public databases. We conducted weighted least squares regression with fixed effects for the pooled data and used Blinder–Oaxaca decomposition to identify sources of outcome variance between the two countries. Results: The average LTC utilization rate was 6.8% in Korea and 18.2% in Japan. Expenditures per recipient were approximately 1.4 times higher in Japan than in Korea. The difference in the utilization rate was mostly explained by between-country differences in supply- and demand-related factors, whereas the difference in expenditures per recipient was largely attributed to unobserved country-specific factors. Conclusion: The current findings suggest that LTC utilization is determined largely by the demographic and functional characteristics of older people, whereas expenditures are more likely affected by institutional factors such as the insurance governance scheme and the policy choice of the target population segment and coverage. The results suggest that strategic choice of LTC institutional schemes is required to ensure financial sustainability to meet changing demands caused by population aging.

Published: July 2022

Background and aims: This study aimed to compare the effect of the mindfulness-based stress reduction (MBSR) with cognitive approach, with that of the spiritual therapy with Islamic approach on quality of life among hypertensive cardiac patients. Methods: All cardiovascular patients referred to the cohort center in Shahrekord in 2019 were included in this semi-experimental (pretest-posttest design) study. Using convenience sampling method, 75 patients were selected and randomly divided into two experimental groups and one control group in such a way that each group included 25 individuals. The McNew quality of life questionnaire was used to collect the required data. All groups received standard medical drugs under the supervision of a cardiologist. In addition to standard medical treatment, the experimental groups underwent MBSR with a cognitive approach (8 sessions lasting 90 minutes) and spiritual therapy based on Islam (8 sessions lasting 90 minutes); The control group received no non-medical intervention. Data were analyzed by using AVOVA and paired t test. Results: The overall score of quality of life in the MBSR and spiritual therapy groups increased significantly after the intervention (P<0.001). As for the control group, however, the overall score of quality of life remained unchanged after the intervention (P=0.10). Significant differences were observed in the total scores of quality of life among the three groups so that the mean score of the difference in the total score of quality of life in the spiritual therapy group before and after the intervention was higher than those in other groups (P<0.001). Conclusion: MBSR therapy and specially Islam-based spiritual therapy had the potential to improve the quality of life in hypertensive cardiac patients.

Published: July 2022

Background and aims: Cannabidiol (CBD) oil consumption can positively contribute to controlling the cardiovascular risk factors. Exercise can also be effective in rehabilitating myocardial infarction by strengthening muscle tissue. This study, therefore, aimed to evaluate the effect of eight weeks of swimming training together with CBD oil consumption on PI3K and ERK gene expression in the heart tissue of rats with myocardial infarction. Methods: In this experimental trial, 25 ovariectomized rats with myocardial infarction were divided into five groups, including 1) control, 2) MI 3) MI +training, 4) MI+supplement, and 5) MI +training+ supplement groups. Myocardial ischemia was induced by subcutaneous injection of isoproterenol (50 mg/kg intravenously) in myocardial infarction rats. Groups 3 and 4 received 50 mg/kg CBD as gavage on a daily basis for eight weeks, and groups 2 and 4 performed swimming training five days a week. One-way analysis of variance (ANOVA) with Tukey’s post hoc test was performed to analyze the findings (P<0.05). Results: Induction of myocardial infarction contributed significantly to reducing PI3k and ERK gene expression in the heart tissue (P=0.001). However, swimming training with CBD oil consumption contributed significantly to increasing PI3K (P=0.003) and ERK (P=0.001) gene expression in the heart tissue of rats with myocardial infarction. Conclusion: Seemingly, swimming training along with CBD oil consumption had more favorable effects on improvement of PI3K and ERK gene expression levels in myocardial infarction than either alone. Therefore, it was recommended that CBD oil together with swimming training should be employed when dealing with myocardial infarction.

Published: July 2022

Background and aims: Lichen planus (LP) and discoid lupus erythematosus (DLE) are two relatively common mucocutaneous lesions whose clinical and histopathological features overlap in some cases. The present study aimed to distinguish between these two lesions histopathologically in order to treat them more accurately. Methods: In a cross-sectional descriptive-analytical study, 29 and 48 microscopic slides of skin samples of DLE and LP, respectively, were examined in the pathology archive of Al-Zahra hospital of Isfahan from 2008 to 2018. The slides prepared by hematoxylin-eosin staining were examined simultaneously and blindly by three pathologists with a light microscope and compared according to certain histopathological criteria. Then obtained data were analyzed by SPSS version 24 using chi-square, Fisher’s exact, Mann-Whitney, and t tests (P<0.05). Results: Based on the findings, the presence of hyperparakeratosis with superficial hyperorthokeratosis, epithelial atrophy, deep perivascular infiltration, presence of edema in the papillary dermis, presence of plasma cells with lymphohistiocytes in inflammatory infiltration, and presence of mucin in the dermis were significantly higher in DLE than in LP (P<0.05). On the other hand, the intensity of lichenoid infiltration, presence of saw tooth hyperplasia of rete ridges, presence of cleft between the epithelium and connective tissue, spongiosis, hyperorthokeratosis alone, and wedge-shaped hypergranulosis were significantly higher in LP than in DLE (P<0.05). Conclusion: Perieccrine and perifollicular inflammation, presence of Civatte bodies (CBs), abundance of fibrosis, presence of pale keratinocytes, and presence of pseudoepitheliomatous hyperplasia were not the criteria for differential diagnosis of LP and DLE.

Authors: Vilarindo de Sousa Sheila
Published: July 2022

Para atender a demanda dos consumidores, cada vez mais preocupados com a saúde e bem estar, estratégias como a modificação do perfil de ácidos graxos dos produtos oriundos de ruminantes (carne e leite) têm sido adotadas, para obter uma menor proporção de ácidos graxos saturados (AGS) os quais geralmente estão associados ao risco de desenvolvimento de doenças cardiovasculares. A inclusão de fontes lipídicas, como por exemplo os óleos vegetais, ricos em ácidos graxos insaturados na dieta de ruminantes, têm tido como objetivo melhorar a eficiência de utilização de energia, uma vez que apresenta menor incremento calórico em comparação aos carboidratos, bem como melhorar os aspectos qualitativos da carne, principalmente no que se refere ao perfil de ácidos graxos, e aumento dos compostos funcionais da carne. Entretanto, devido à natureza alimentar dos ruminantes ser associada ao consumo de forragens, pobres nesse nutriente, há uma limitação em sua utilização, uma vez que são tóxicos aos microrganismos ruminais. Assim, pesquisas avaliando a inclusão de fontes lipídicas na dieta de animais ruminantes, têm sido realizadas como alternativa alimentar para melhorar a qualidade da carne, minimizando os efeitos sobre a fermentação ruminal.

Authors: İME Gamze
Published: July 2022

Cedit hareketi Türk milli bilincinin gelişimi ve Türk halklarının bağımsızlık mücadelelerine önemli fikri etkisi olmuş bir hareket olarak nitelendirilir. Usul-u Cedit (Yeni Usul) akımı ise eğitim ve kültür alanlarında çağın gerisinde kalmanın sebeplerini belirlemek ve bu soruna uygun çözümler üretmek amacını güden bir yaklaşım olarak karşımıza çıkar. Bu sayede eğitim alanında yapılacak olan reformlarla 19. yüzyılda Türk dünyasının içinde bulunduğu geri kalmışlığın önüne geçilmek istenmiştir. İsmail Gaspıralı, hareketin en bilinen ve en önemli isimlerinden biridir. Onun çalışmalarında da görüldüğü üzere söz konusu duruma öncelikli ve uygun çözüm olarak eğitim sisteminin değiştirilmesi, geliştirilmesi ve toplumun bu konuda eğitilmesi bulunmuştur. Fakat bu yaklaşıma toplumdaki bazı kesimler tepki vermiş ve muhalefet etmişlerdir. Kadimci olarak nitelendirilen kimseler, yenileşmeyi adeta bir yozlaşma olarak görmüşlerdir. Sonuçta İsmail Bey’in çıkardığı Tercüman gazetesi vasıtasıyla eğitim-öğretimde yenileşmeyi öngören bakış açısı, tüm Türk-İslam coğrafyasında yayılma imkânı bulmuştur. Eğitimdeki bu noksanlığın farkında olan İsmail Gaspıralı’nın başlattığı bu usul-ü cedit hareketi, başta Rusya'da yaşayan Müslüman ve Türk topluluklarının ulusal bilinçlerini kazanmasında, Türk milliyetçiliğinin gelişmesinde ve bu ülkede yaşayan halkların hak arama mücadelesinde önemli görevleri yerine getirmiştir. Bu çalışmada eski usul eğitim anlayışı ile Rusya Müslümanlarından İsmail Gaspıralı’nın geliştirdiği yeni usul eğitim tarzının karşılaştırması yapılarak usul-ü cedit’in Çağdaş Türk Dünyasına katkıları incelenmiştir.

Published: July 2022

El objetivo del estudio fue Explorar las concepciones pedagógicas y actitudes de los docentes de la Facultad de la Educación, el Arte y la Comunicación de la Universidad Nacional de Loja, frente a la inclusión de estudiantes con necesidades educativas específicas (NEE). Se la realizó a través de un enfoque cuantitativo, de corte transversal descriptivo, mediante una encuesta a una muestra de 76 docente. Los resultados destacan la coherencia entre las concepciones pedagógicas y las actitudes, basadas en un modelo integracionista, es decir esperar que sea el alumno el que se adapte al sistema educativo, sin respetar sus necesidades específicas en el aprendizaje. En conclusión, se demuestra que pese a estar legalmente establecido el derecho a una educación inclusiva en la Constitución del Ecuador, no es suficiente el ejercicio de esta, se necesita desaprender constructos y paradigmas que ya no responden a la complejidad del mundo actual.

Published: July 2022

We report on the generation of few-ns pulses with kW peak power in the red and orange spectral range obtained from a passively Q-switched Pr3+:YLF laser. A compact resonator and thorough investigation of the Co:MgAl2O4 saturable absorber’s initial transmission enables peak powers in excess of 1.1 kW at pulse durations of 2.4 ns and 5.3 ns at 640 nm and 607 nm, respectively. These are the shortest pulse durations among any Q-switched Pr3+ laser and make this system a suitable front-end for efficient frequency doubling into the ultraviolet range.

The research work was conducted in a cooled plastic tunnel to Study the response of cucumber to different doses of soluble nitrogen, phosphorus and potassium (N, P and K) fertilizers at Shambat Research Station, Sudan, during the seasons, 2020 and 2021. The experiment was laid out in Randomized complete block design (RCBD) with four replications. The hybrid variety of cucumber “Mawasim” was used. Three combination doses of nitrogen, phosphorus and potassium fertilizers (20gm N + 13.3gm P + 23.3gm K), (40gm N + 26.7gm P + 46.7gm K) and (80gm N + 53.4gm P + 93.4gm K) per m2 in addition to control (no fertilizer) were applied. The fertilizer doses were added twice weekly starting two weeks from sowing date. The data collected included plant growth parameters, the yield, yield and its components and fruit quality. The combined ANOVA was used for analysis. The results showed that application of fertilizers significantly increased all growth, yield and its components compared to control. The medium dose (40gm N + 26.7gm P + 46.7gm K/ m2), gave significant positive effects on all parameters tested in both seasons. The growth and yield values were decreased with increased fertilizer dose. This indicates that the medium dose from N, P and K can be recommended for cucumber production under the cooled plastic tunnels.

OBJETIVO: Comparar a taxa de incontinência urinária em mulheres praticantes de CrossFit, mulheres praticantes de outras modalidades esportivas e mulheres sedentárias.MÉTODOS: Foram entrevistados 232 indivíduos para este estudo observacional transversal, sendo 72 mulheres praticantes de CrossFit®, 78 mulheres praticantes de outras modalidades esportivas, 82 mulheres sedentárias. Foram aplicados questionários online, incluindo perguntas como: idade, estatura e massa corporal (utilizados para cálculo do índice de massa corporal), filhos e quantidade, tipo de parto, realização de cirurgia pélvica prévia, prática de atividade física, a modalidade praticada, e ocorrência de perda de urina frequente nos últimos meses. ANOVA foi utilizada para investigar uma possível diferença entre as taxas de incontinência urinária entre os grupos.RESULTADOS: A idade média das participantes foi de 29 anos (DP 10), com índice de massa corporal médio de 24,8 (DP 5,6), sendo que 75 (32%) das mulheres tiveram, pelo menos, um filho, sendo a maioria (60%) de parto normal em pelo menos uma gestação. Taxa de incontinência urinária encontrada na amostra total foi de 15%. Quando realizada comparação da taxa entre os grupos, não foram observadas diferenças estatisticamente significativas (p>0,05), indicando que todos apresentaram taxas de incontinência urinária similares. CONCLUSÃO: A ausência de diferença significativa nas taxas de incontinência urinária entre os grupos de mulheres praticantes de CrossFit®, praticantes de outras modalidades esportivas, e mulheres sedentárias evidenciam que, aparentemente, independente da prática ou não de modalidades esportivas, tal aspecto parece não favorecer o surgimento da incontinência urinária em mulheres saudáveis.

Os docentes precisam estar capacitados para o uso de metodologias e estratégias mais dinâmicas. O estudo das metodologias ativas, sobretudo na ótica da Aprendizagem Baseada em Projetos (ABP) possui essa proposta, dar autonomia aos estudantes. Com isso, desenvolvemos um projeto de ensino voltado aos estudantes do curso de Licenciatura em Química do IFG - Câmpus Uruaçu, com o objetivo de prepará-los melhor para o uso das metodologias ativas. O projeto foi desenvolvido a partir da apresentação da ABP e ABF. Ao final, cada grupo apresentou um projeto para o uso da ABP no ensino de química. De forma geral, os licenciandos conseguiram apresentar problemas com impactos sociais, econômicos e científicos, no entanto, tiveram dificuldades na contextualização dos problemas e as estratégias de resolução do projeto não propunham muita autonomia aos estudantes. Apontando a necessidade de ter mais formações no uso de metodologias ativas.

Authors: Maulyda Mohammad Archi , Umar Umar
Published: July 2022

The Covid-19 pandemic has a significant impact on Indonesia's education today. Students from both junior and senior batches of universities must experience changes in learning systems and models. Demands for change are felt not only by students but also by teachers. The teacher must meet the demands of distance learning. This also impacts on the use of appropriate tools in evaluating student learning outcomes. The Quizizz website is one of the teacher's tools for evaluating. However, it is not yet known whether Quizizz is the right tool for evaluating. The purpose of this study was to determine the effectiveness of using Quizizz as an evaluation tool. The research method is quantitative with quasi-experimental design. There are control and experiment classes, each with a sample of 37 students of Elementary School Teacher Education Study Program. Data obtained in the form of test score figures will be analyzed using independent t-test to find out whether the two data groups have significant mean differences. The "t-test for Equality of Means" column shows the results of the independent t-test. Sig. Value from the t-test is 0.138. If α = 0.05, then Sig.> 0.05. This shows that there is no significant difference between the experimental class and the control class. The results of the data analysis showed that there were no significant differences between the experimental and control classes. This shows that the use of the Quizizz website is less effective as a means of evaluating learning outcomes.The use of the quizizz website as a means of evaluating student learning outcomes needs to be further examined

Purpose. This study aims to describe the potential of DOAJ as an alternative to open source learning during a pandemic.Method. The method used in this research is the literature study.Result and discussion. Based on the literature search, DOAJ's potential as OER during the pandemic can be seen based on the characteristics of DOAJ which are digital, online, free, and free of copyright and licensing restrictions. This study concludes that DOAJ has the potential to be used as an alternative source of open learning during a pandemic because of its characteristics that support efforts to prevent Covid-19 transmission. Given the potential of DOAJ as an alternative to OER during the pandemic, the use of DOAJ as an alternative to OER can continue to grow after the pandemic period. Therefore, further studies regarding the level of use of DOAJ as an alternative to OER or the level of DOAJ compliance with user information needs will be an interesting study to be investigated in future studies.
