Published: May 2022

Background: Hysterosalpingography is the investigative modality of choice for the evaluation of the uterine cavity, fallopian tubes, and adjacent peritoneal cavity. Objective were to compare the effectiveness of paracetamol and diclofenac in pain relief during hysterosalpingography.

Methods: This trial was conducted at the radiology departments and infertility clinics of the Federal Medical Centre, Yenagoa, and Niger Delta University Teaching Hospital, Okolobiri, both in Bayelsa State, Nigeria, from June 2021-March, 2022, and 380 infertile women undergoing hysterosalpingography were equally randomised into two groups. Group I received paracetamol, while group II received diclofenac prior to the procedure. Data were analysed using statistical product and service solutions for Windows® version 25. Student’s t-test was used to compare sample means, and the Chi-square test was used to compare the proportions.

Results: The women experienced the least pain during insertion of speculum, with an overall mean pain score at this step of 0.8±0.9, while the most painful step was instillation of contrast, the overall mean pain score at this step being 4.3±1.9. While 38, 20.0%, women in the paracetamol group expressed severe pain during contrast instillation, only 14, 7.4%, women in the diclofenac group expressed severe pain at this step, and this was statistically significant (ꭓ2=22.05; p=0.001). The mean pain scores at all steps of the procedure were significantly higher in the paracetamol group than in the diclofenac group (p≤0.005).

Conclusions: Compared to paracetamol, diclofenac is a more effective analgesic for pain relief during hysterosalpingography.

Authors: Prasad Krishna , Gray Adam , Edward Lauren
Published: May 2022

E-cigarettes have the potential to reduce the harm caused by cigarette smoking; however, product likeability and product satisfaction are important in encouraging smokers to switch to less harmful products.  Actual use studies play a key part in evaluating the reduced risk potential of tobacco and nicotine products. User’s puffing behaviour, including puff duration and sensory effects were evaluated for two types of e-cigarette device: a coil-and-wick ‘pen-type’ device (Vype ePen3), and a ceramic block-and-plate ‘pod-type’ device (Vype ePod) with 18 mg/ml nicotine e-liquid. Puffing topography was recorded for these devices with two groups (n=52 each) of adult regular vapers (age 21-64 years) following a fixed 10 puffs protocol where subjects vaped through a special holder attached to a puffing analyser.  The sensory characteristics of the aerosol were evaluated using a questionnaire.  Mean puff volume was significantly greater (p≤0.0001) for ePen3 than for ePod (79.8 vs 49.4 ml), while puff duration and puff interval were similar (2.13 vs 2.29 s and 8.9 vs 10.3 s, respectively). Notably, MLE to aerosol and nicotine from ePen3 and ePod were similar (3.89 vs 4.80 mg and 0.06 vs 0.07 mg respectively) despite of very different designs of the devices.  Participants reported similar overall likeability and other sensory scores for ePen3 and ePod.  In summary, the puffing topography attributes support the CORESTA recommended method no. 81, (CRM81) puffing regime, used for in vitro and chemical analysis.  The MLE to nicotine per session from both the products were lower than a typical 6 mg cigarette.
Helping Struggling Students and Benefiting All: Peer Effects in Primary Education
Authors: Berlinski Samuel , Busso Matías , Giannola Michele
Published: May 2022

We exploit the randomized evaluation of a remedying education intervention that improved the reading skills of low-performing third grade students in Colombia, to study whether providing educational support to low-achieving students affects the academic performance of their higher-achieving classmates. We find that the test scores of non-treated children in treatment schools increased by 0.108 of a standard deviation compared to similar children in control schools. We interpret the reduced-form effect on higher-achieving students as a spillover effect within treated schools. We then estimate a linear-in-means model of peer effects, finding that a one-standard-deviation increase in peers' contemporaneous achievement increases individual test scores by 0.679 of a standard deviation. We rule out alternative explanations coming from a reduction in class size. We explore several mechanisms, including teachers' effort, students' misbehavior, and peer-to-peer interactions. Our findings show that policies aimed at improving the bottom of the achievement distribution have the potential to generate social-multiplier effects that benefit all.

Introducción: Desde el 2016 Colombia enfrenta un escenario humanitario generado por la llegada de población migrante y refugiada venezolana. En respuesta, el sistema de salud colombiano ha buscado garantizar el acceso de esta población a los servicios de salud. Sin embargo, en la práctica permanecen diferentes desafíos para garantizar la cobertura universal en salud en sus tres dimensiones. Objetivo: Profundizar en el conocimiento que se tiene sobre los desafíos que enfrenta la población migrante y refugiada venezolana en el derecho a la salud en Colombia en el 2019. Materiales y métodos: Se realizó una investigación cualitativa con 12 grupos focales de migrantes y refugiados venezolanos en seis ciudades de Colombia que en el 2019 concentraban los volúmenes más altos de población migrante y refugiada. Resultados: Se identificaron barreras en los tres pilares de la cobertura universal en salud. En aseguramiento se evidenció que la población migrante y refugiada venezolana, tanto irregular como regular, está enfrentando barreras para la afiliación al sistema de salud; en acceso a los servicios se identificaron dificultades generadas por las diferentes interpretaciones que los prestadores hacen de las urgencias médicas; en protección financiera se identificó que las personas migrantes y refugiadas están asumiendo los costos económicos de buena parte de los servicios de salud que requieren. Conclusiones: Entre la población migrante y refugiada venezolana tanto en condición irregular como regular se identificaron barreras en la implementación de la política para la atención en salud, las cuales están afectando la realización de la cobertura universal en salud.

An overview of the underlying legal and psychological issues of surrogacy in Islam
Authors: Mehfooz Musferah , Imran Asma , Azhar Sarah
Published: May 2022

Purpose of the study: This paper attempted to deal with the issue of Surrogacy from various angles by considering the very essence of Islamic law, i.e., of Shariah. Procreation has considered sacred in Islam; no doubt, it is one of the five fundamental objectives of Shariah (Islamic law), notwithstanding the protection of self, religion, honor, and property. In Muslim societies, religion strongly influences behavior, culture, practices, and policy-making; therefore, according to the Islamic viewpoint, just legitimate pregnancy would result from intermingling sperm and ovum of a legitimately wedded couple.

Research methods: The methodology applied in the discussion is a critical analysis based on inductive and deductive approaches to the collected data. The data for this study has been collected from various secondary sources like Academic Research Papers, Research Journals, and other Electronic Sources.

Main findings: the conclusion arrived at in the article is that Surrogacy is of various categories, some of which may be Islamically valid and some others invalid. In light of the discussion, it is also concluded that Surrogacy also leads to psychological confusion over the question of motherhood, which Islam considers the highest form of human love and compassion.

Application of the study: This study would leave significant implications for legal and social dimensions. The only way to minimize the differences of opinions over any issue in Islamic jurisprudence is deliberation over the issue concerned from the angle of the objectives of Sharīᶜah (Maqāsid al-Sharīᶜah). The issue of Surrogacy as to its validity or invalidity from the Islamic perspective may be resolved in this way. Therefore, the study would doubtlessly help reduce social, physiological, and legal issues based on surrogate practice.

Originality and novelty of the study: The least attention has been given to legal and psychological issues in the existing literature. The present study aims to deal with the legal, psychological, and even social issues caused by the practice of Surrogacy. Therefore, this is the first study that has investigated the practice of Surrogacy from multiple perspectives, particularly analyzing them in the framework of the objectives of Sharīᶜah.
Uwarunkowania współczesnej przedsiębiorczości
Authors: Majkut Robert
Published: May 2022

Artykuł omawia w sposób teoretyczny i empiryczny relatywną deprywację oraz mechanizm egzystencjalny jako czynniki przedsiębiorczości. Motywacja do zaangażowania się w działalność przedsiębiorczą oparta na relatywnej deprywacji jest efektem rozbieżności pomiędzy poziomem aspiracji a stopniem ich rzeczywistej realizacji. W takiej sytuacji pojawia się chęć tego, żeby działać na rzecz osiągnięcia wyższego standardu życiowego. Z kolei mechanizm egzystencjalny wskazuje, że zaangażowanie się w działalność gospodarczą na własny rachunek jest konsekwencją braku możliwości zdobycia w inny sposób środków pieniężnych niezbędnych do zaspokajania potrzeb. Oba te mechanizmy mogą wyjaśniać przyczyny angażowania się w działalność gospodarczą na własny rachunek każdej osoby, ale w znacznym stopniu nadają się do analizy przedsiębiorczości imigrantów.
Euroregion as the highest organizational and functional level of cross-border cooperation
Authors: Tsekhanovych Victor
Published: May 2022

In modern conditions of expanding the processes of globalization the role of globalization is growing cross-border cooperation of regions, which opens up new opportunities for activation of economic activity in the peripheral territories and increase of economic activity in the peripheral territories their competitiveness. At the end of the last century, the regional the policy of the European Union has moved to a new paradigm-from application of mechanisms to eliminate regional development imbalances through interregional redistribution of resources to mobilization of course-resource potential of territories and application of the principle of subsidiarity. This one the approach was used by the contiguous border regions of Europe, which we have established mutual contacts between state and regional authorities, local self-government bodies, public organizations, and subjects management of territories, joining forces to solve common problems, and from cooperation under certain cross-border agreements we have moved on to cooperation within the framework of euroregions. Thus, the characteristic a feature of modern Europe is the rapid development of international cooperation regions – one of the most effective driving forces of European integration and bringing people together. Cross-border cooperation should be implemented in the context of territorial organization and effective deployment of productive forces. According to European experience, the CBC helps to overcome the territorial imbalance (spatial gaps between production and consumption) of the region’s economy, which is a significant factor, since there are significant developmental imbalances between the border administrative-territorial units of Ukraine and neighboring states. The implementation of this task in practice is carried out by complementarity, improvement and optimization of the territorial structure of the economy, functional combination and coordination of economies, industries and individual industries of border regions of neighboring states involved in cross-border cooperation. Along with this, it is fundamental to maintain a balance (optimal proportions) in the development of all spheres of life of territories on different sides of the border.

Published: May 2022

Niniejszy artykuł daje wgląd w aktualne trendy rozwoju europejskiego przemysłu hotelarskiego poprzez zrozumienie procesów zachodzących w poprzednim okresie. Na podstawie wyników analizy danych internetowej bazy danych Eurostatu można stwierdzić, że popyt na noclegi w Unii Europejskiej był niestabilny w ciągu ostatniej dekady. Wyniki badania pokazują tendencję europejskiego przemysłu noclegowego do zmniejszania się procentowej zmiany noclegów w obiektach noclegowych przez gości z zagranicy, która pojawiła się przed wpływem COVID-19. W ciągu ostatnich kilku lat turystyka krajowa rozwijała się bardziej stabilnie, ale tylko częściowo rekompensuje obecny spadek popytu międzynarodowego. Badanie to potwierdza, że zmiana w możliwościach europejskiego przemysłu hotelarskiego odzwierciedla zmianę w popycie na zakwaterowanie. Wyniki tego artykułu mogą być wykorzystane do zrozumienia pozycji przedsiębiorstwa, zidentyfikowania zagrożeń i szans w czasie kryzysu oraz do skoncentrowania jego zasobów na rozwijaniu unikalnych zdolności, które mogą prowadzić nie tylko do wznowienia działalności, ale także do przewagi konkurencyjnej i rentowności. Aby ułatwić jego realizację przez menedżerów, opracowano Model Krajobrazu Procesowego głównych procesów i podprocesów rozwoju europejskiego przemysłu hotelarskiego.

Decentralizacja fiskalna jako ograniczenie zjawiska Lewiatana
Authors: Guziejewska Beata
Published: May 2022

Monografia zawiera problematykę poświęconą decentralizacji fiskalnej i jej ograniczającej roli w zjawisku rozrastania się sektora publicznego, które określa się Lewiatanem. Nawiązano w niej do tzw. hipotezy Lewiatana sformułowanej przez J.M Buchanana w odniesieniu do zdecentralizowanych struktur finansów publicznych. Przedmiotem rozważań są procesy decentralizacji fiskalnej w szerokim ujęciu: ekonomicznym, politycznym, administracyjnym, socjologicznym i przestrzennym. Analizy oparto w dużym stopniu na dorobku federalizmu fiskalnego.  
Celem monografii jest pogłębienie dorobku teoretycznego w zakresie wykorzystania procesów decentralizacji fiskalnej jako mechanizmu ograniczania i hamowania niebezpiecznego zjawiska Lewiatana. Dokonano przeglądu dotychczasowych badań empirycznych oraz zweryfikowano pozytywnie następujące hipotezy badawcze: 

Decentralizacja fiskalna oparta na wypracowanych w doktrynie założeniach jakościowych ma pozytywny wpływ na efektywność sektora publicznego oraz ogranicza zjawisko Lewiatana.
W warunkach tendencji centralizujących państwo, będących efektem działań pokryzysowych zawiązanych z konsekwencjami pandemii, decentralizacja i decentralizacja fiskalna mogą być mechanizmami ograniczającymi zjawisko Lewiatana.
Wielowymiarowy charakter decentralizacji fiskalnej powoduje, że jej ograniczający wpływ na zjawisko Lewiatana nie jest potwierdzany empirycznie w każdych warunkach miejsca i czasu. 
Decentralizacja fiskalna jest istotnym elementem formułowania nowego paradygmatu finansów zrównoważonych w okresie po pandemii.  

W opracowaniu uwzględniono współczesne wyzwania procesów decentralizacji fiskalnej, takie koncepcję ESG (Environmental-Social-Governance) oraz konsekwencje pandemii. Rozważania mają charakter interdyscyplinarny i kończą się propozycją włączenia procesów decentralizacji fiskalnej do nowego paradygmatu finansów zrównoważonych.

Authors: Kalomo Eveline Ndinelao , Jun Jung , Lee Kyoung Hag
Published: May 2022

Namibia has one of the highest HIV prevalence rates in the world. Older relatives in Namibia are taking the lead role in caring for children living with HIV, or orphaned as their parents had HIV. There has been a growing attention to the well-being and mental health of these older adult caregivers in sub-Saharan Africa; however, there is a lack of information on the intertwined factors such as loneliness and depression to their life satisfaction. Therefore, this study aimed to explore the relationship between loneliness and depression on life satisfaction among older caregivers of children living with HIV or AIDS in rural Namibia. This cross-sectional study recruited 100 Oshiwambo speaking caregivers over age 60 in the Omusati region to complete a study instrument measuring their levels of loneliness, depression and perceived life satisfaction. Using hierarchical regression method, this study found that both loneliness and depression were significantly associated with lower levels of perceived life satisfaction among our sample. Medical care or insurance and awareness of social services were both associated with higher levels of perceived life satisfaction. Social service professionals and policy makers in Namibia should consider designing culturally appropriate interventions aimed at addressing these important mental health related concerns of older rural caregivers.

Severity of grinder injuries and related factors compared with other high-rotation cutting tool injuries: a multicenter retrospective study from 2011 to 2018
Authors: Song Juni , Jeon Yang Bin , Jang Jae Ho , Cho Jin Seong , Choi Jae Yeon , Choi Woo Sung
Published: May 2022

Purpose: This study aimed to identify the characteristics of patients injured by high-rotation cutting tools and the factors related to the severity of their injuries.Methods: Adult patients (≥18 years), who presented to the emergency department (ED) after a high-rotation cutting tool injury and who were registered in the Korean Emergency Department-based Injury In-Depth Surveillance (2011–2018) database, were included. Patients’ demographic characteristics, injury-related factors, and Injury Severity Scores were collected. All included cases were categorized into two groups according to the tool that caused the injury: grinder versus nongrinder. The characteristics of the two groups were compared, and the factors associated with the severity of injuries were investigated.Results: Among 8,697 ED visits, 4,603 patients had been using a grinder and 4,094 had been using a nongrinder tool. The most frequently injured body part while using a grinder was the hand (46.4%), followed by the head (23.0%). While using a nongrinder tool, the most frequently injured body part was also the hand (64.0%), followed by the lower leg (11.4%). The odds of a severe injury were affected by patient age (odds ratio [OR], 1.024; 95% confidence interval [CI], 1.020–1.028) and using a grinder (OR, 2.073; 95% CI, 1.877–2.290). The odds of a severe injury using a grinder were higher in arm injuries (OR, 1.60; 95% CI, 1.40–1.83) and multiple-part injuries (OR, 1.998; 95% CI, 1.639–2.437). The odds of a severe injury using a grinder were lower for head injuries (OR, 0.481; 95% CI, 0.297–0.781).Conclusions: Injuries from grinders were more likely to affect the head and neck than nongrinder injuries, despite the lower severity. The current lack of regulations on grinders in occupational safety and health standards warrants relevant legislation and the development of applicable safety equipment.
Predicting Velocity and Direction of Ocean Surface Currents using Elman Recurrent Neural Network Method
Authors: Kusnanti Eka Alifia , Novitasari Dian C. Rini , Setiawan Fajar , Fanani Aris , Hafiyusholeh Mohammad , Permata Sari Ghaluh Indah
Published: May 2022

Background: Ocean surface currents need to be monitored to minimize accidents at ship crossings. One way to predict ocean currents—and estimate the danger level of the sea—is by finding out the currents’ velocity and their future direction.
Objective: This study aims to predict the velocity and direction of ocean surface currents.
Methods: This research uses the Elman recurrent neural network (ERNN). This study used 3,750 long-term data and 72 short-term data.
Results: The evaluation with Mean Absolute Percentage Error (MAPE) achieved the best results in short-term predictions. The best MAPE of the U currents (east to west) was 14.0279% with five inputs; the first and second hidden layers were 50 and 100, and the learning rate was 0.3. While the best MAPE of the V currents (north to south) was 3.1253% with five inputs, the first and second hidden layers were 20 and 50, and the learning rate was 0.1. The ocean surface currents’ prediction indicates that the current state is from east to south with a magnitude of around 169,5773°-175,7127° resulting in a MAPE of 0.0668%.
Conclusion: ERNN is more effective than single exponential smoothing and RBFNN in ocean current prediction studies because it produces a smaller error value. In addition, the ERNN method is good for short-term ocean surface currents but is not optimal for long-term current predictions.
Keywords: MAPE, ERNN, ocean currents, ocean currents’ velocity, ocean currents’ directions
Deep Learning Approaches for Multi-Label Incidents Classification from Twitter Textual Information
Authors: Anggraeni Sherly Rosa , Ranggianto Narandha Arya , Ghozali Imam , Fatichah Chastine , Purwitasari Diana
Published: May 2022

Background: Twitter is one of the most used social media, with 310 million active users monthly and 500 million tweets per day. Twitter is not only used to talk about trending topics but also to share information about accidents, fires, traffic jams, etc. People often find these updates useful to minimize the impact.
Objective: The current study compares the effectiveness of three deep learning methods (CNN, RCNN, CLSTM) combined with neuroNER in classifying multi-label incidents.
Methods: NeuroNER is paired with different deep learning classification methods (CNN, RCNN, CLSTM).
Results: CNN paired with NeuroNER yield the best results for multi-label classification compared to CLSTM and RCNN.
Conclusion: CNN was proven to be more effective with an average precision value of 88.54% for multi-label incidents classification. This is because the data we used for the classification resulted from NER, which was in the form of entity labels. CNN immediately distinguishes important information, namely the NER labels. CLSTM generates the worst result because it is more suitable for sequential data. Future research will benefit from changing the classification parameters and test scenarios on a different number of labels with more diverse data.
Keywords: CLSTM, CNN, Incident Classification, Multi-label Classification, RCNN
Ensemble-based Methods for Multi-label Classification on Biomedical Question-Answer Data
Authors: Abdillah Abid Famasya , Putra Cornelius Bagus Purnama , Apriantoni Apriantoni , Juanita Safitri , Purwitasari Diana
Published: May 2022

Background: Question-answer (QA) is a popular method to seek health-related information and biomedical data. Such questions can refer to more than one medical entity (multi-label) so determining the correct tags is not easy. The question classification (QC) mechanism in a QA system can narrow down the answers we are seeking.
Objective: This study develops a multi-label classification using the heterogeneous ensembles method to improve accuracy in biomedical data with long text dimensions.
Methods: We used the ensemble method with heterogeneous deep learning and machine learning for multi-label extended text classification. There are 15 various single models consisting of three deep learning (CNN, LSTM, and BERT) and four machine learning algorithms (SVM, kNN, Decision Tree, and Naïve Bayes) with various text representations (TF-IDF, Word2Vec, and FastText). We used the bagging approach with a hard voting mechanism for the decision-making.
Results: The result shows that deep learning is more powerful than machine learning as a single multi-label biomedical data classification method. Moreover, we found that top-three was the best number of base learners by combining the ensembles method. Heterogeneous-based ensembles with three learners resulted in an F1-score of 82.3%, which is better than the best single model by CNN with an F1-score of 80%.
Conclusion: A multi-label classification of biomedical QA using ensemble models is better than single models. The result shows that heterogeneous ensembles are more potent than homogeneous ensembles on biomedical QA data with long text dimensions.
Keywords: Biomedical Question Classification, Ensemble Method, Heterogeneous Ensembles, Multi-Label Classification, Question Answering

University lecturers’ preparedness to use technology in teacher training of mathematics during COVID-19: The case of Ethiopia
Authors: Machaba F. , Bedada T.
Published: May 2022

The study aimed to investigate Ethiopian university lecturers’ readiness to use technology for teaching mathematics at the tertiary level during the COVID-19 pandemic when they were compelled to adapt to distant education. Using Google Forms, online questionnaires were distributed to 41 lecturers in three Ethiopian universities, of whom eighteen participated. Before the research, the questionnaire was piloted with eight lecturer participants to categorise questions and validate the instrument using the Rasch measurement model. The questionnaire was locally developed based on guidelines from the literature. It purposed to investigate university lecturers’ individual preparedness for technological instruction in terms of their knowledge, beliefs and current, and historical exposure to this mode of instruction. As a counterbalance, some circumstantial factors influencing their readiness were investigated too. Lecturers’ optimistic beliefs about using educational technologies have been found to contrast with some disabling circumstantial factors. This study revealed that the lecturers were generally able and interested in integrating technology into the teaching process but that barriers, primarily at the institutional level, hindered them from doing so. In addition to the technologies suggested in the questionnaire, participants enriched the research findings by adding more possible technologies that lecturers may use for educational purposes. The data was analysed using WINSTEPS (Student Version of WINSTEPS 4.7.0.0) and SPSS version 20. The results showed the reliability of using the instrument was 0.77 based on Cronbach’s alpha. The PT-measure correlation value determined the construct validity (PMC), ranging from 0.23 to 0.71 except item PUT15’s infit and outfit MNSQ between 0.1 to 1.86 and ZSTD range -1.05 to 1.61, which was acceptable. The fit statistics showed that the person separation index, 1.97, was considered good and that the item separation index, 0.63 was within an acceptable range. Person and item reliability were at 0.8 and 0.28, respectively. The result indicated that the new instrument with five items after eliminating unfit items (such as items FAT19, PTT10, KDT1, PTT8 and PTT 12) was reliable and valid to measure the use of technology in the teaching and learning process of the university lecturers.

La cáscara de naranja (Citrus sinensis L.) se ha considerado como un residuo debido al elevado costo y la compleja gestión de su procesamiento, convirtiéndose en un problema de contaminación ambiental. Por esta razón, se ha prestado gran atención a la valorización de este residuo agroindustrial para obtener beneficios monetarios con una reducción del volumen de residuos orgánicos y la posibilidad del desarrollo de tecnologías eficientes para generar y almacenar energía eléctrica. Este trabajo presenta un proceso térmico ambientalmente amigable para producir un carbón conductivo. Primero las cáscaras de naranja se lavaron por baño ultrasónico y se secaron al sol y en mufla. Posteriormente pedazos de cáscara de naranja deshidratada se cubrieron completamente con arena de mar de grano fino y se carbonizaron a 1000 °C durante 1 hora. Después, el biocarbón fue estudiado por voltametría cíclica. La capacitancia eléctrica de doble capa de la muestra fue estimada para conocer el comportamiento electroquímico del carbono en el electrolito. El material de carbón sintetizado mostró una capacitancia específica de 272 F/g a 20 mV/s. Los resultados observados demostraron que el nuevo proceso térmico propuesto produce carbono grafitizado con buenas propiedades electroquímicas a bajo costo. Además, esta propuesta contribuye con el desarrollo de nuevos materiales conductores de carbón usando un tratamiento térmico simple, económico y respetuoso con el medio ambiente a partir de biomasa residual de bajo valor.
Yield and water productivity variation of Boro rice with irrigation strategies and transplanting dates under climate change – a case study in south-western Bangladesh

Climate change has imposed major uncertainties on food and water security in Bangladesh. Understanding the recent changes in potential yield and water productivity of major crops is essential to formulate effective adaptation strategies under climate change conditions. This study assessed the yield and water productivity variation of dry season Boro rice with different irrigation regimes and transplanting dates over long-term (1985-2017) in a south-western District (Khulna) of Bangladesh using AquaCrop model. The evaluation of yield and water productivity was done for five transplanting dates (1st & 15th of December and January and 1st of February) and four irrigation strategies (fixed short- and long-interval irrigations, and measured irrigation with ‘low stress, low dose’ and ‘high stress, high dose’). Transplanting rice seedlings on 1st December results in 17% yield increase compared to transplanting on 1st January. There are significant (p£0.05) increasing trends of attainable biomass, grain yield and water productivity of Boro rice. The measured irrigation practices are superior to the traditional fixed irrigation practices. The ‘low stress, low dose’ irrigation strategy increases irrigation-water productivity and provides an opportunity to exploit the possible benefits of climate change. Adjustment of the irrigation strategy can reduce water usage without reducing the potential yield of Boro rice with an eventual increase in irrigation-water productivity, while adjustment of the transplanting date can increase potential yield with additional water usage. These findings would help develop suitable agricultural adaptation strategies for irrigated rice cultivation under climate change.
Az újmédia szerepe az olvasóvá nevelésben
Authors: Nagy Balázs
Published: May 2022

Az olvasóvá nevelés folyamatának alapvetően tudatos és irányított, az újabb kutatási eredményeket is figyelembe vevő eljárásnak kell lennie. Manapság e kritérium teljesülésének az egyik fő akadályát sokan abban látják, hogy az újabb médiumok (internet, filmek, játékok) világa sokkal vonzóbb lett a fiatalok számára. A társadalmi változásokkal azonban nem lehet szembehelyezkedni, sokkal inkább alkalmazkodni kell hozzájuk. Az olvasói szokások megváltozása világméretű jelenség, a mai kor olvasói egyre több könyvön kívüli olvasási élménnyel találkoznak, ezért törekedni kell arra, hogy a pedagógusok mindezeket felhasználják az olvasóvá nevelés érdekében. A tanulmány arra keresi a választ, hogyan támogathatják az olvasóvá válást és az olvasó tájékozódását az újmédia eszközei. Először az olvasóvá nevelés témakörét járja körül, majd az újmédia jellegzetességeit és a kultúrára gyakorolt hatását körvonalazza, végül pedig ennek azon eszközeit, műfajait és alkalmazásait veszi sorra – az online folyóiratoktól a közösségi oldalakon át a könyvesvlogokig és podcastokig –, amelyek szerepet játszhatnak az olvasóvá nevelésben.
A második nyelv hatásai az anyanyelvre eltérő nyelvtanulási kontextusokban
Authors: Bátyi Szilvia , Airi Kemppainen
Published: May 2022

A tanulmány azt a kérdést vizsgálja, hogy milyen hatással vannak az anyanyelvre a különböző nyelvtanulási kontextusok. A vizsgálat a tanulmányaikat Magyarországon megkezdő orosz ajkú hallgatók beszélt és írott nyelvi produkciójára terjed ki, és az eredményeiket oroszországi angol szakos és egynyelvű társaikéval veti össze. A kutatás eszközei a nyelvhasználati és a nyelvjártassági kérdőív, a szemantikus és a betűfluencia-tesztek, a képregénymesélés és az írott produktum létrehozása. A vizsgálat longitudinális: a résztvevők nyelvi teljesítményét a tanulmányok megkezdésekor és négy hónap elteltével méri. Az eredmények megmutatják, hogy a nem anyanyelvi nyelvtanulási környezet hogyan hat az anyanyelvre, ez a szókincsgazdagság csökkenésében és a szünetek százalékos arányának a növekedésében mutatkozik meg.
Az írott és hallott anyanyelvi szövegértés vizsgálata harmadik osztályban
Authors: Bajkó Edina
Published: May 2022

A pedagógiai gyakorlat azt mutatja, hogy a már írástudó gyermekek vizuális szövegértése fejlettebbé válik, azaz könnyebben megértenek és megjegyeznek írott nyelvi szövegeket. A kutatás kérdésfeltevése az, hogy a harmadik osztályos tanulóknál vajon a hallott vagy az írott szövegek értése fejlettebb, illetve hogy a munkamemória mennyiben játszik szerepet a szövegértés folyamatában. A vizsgálat mintáját harminckét harmadik osztályos tanuló képezi két nagyváradi iskolából. A felmérés három alkalomból állt. A tanulók mindhárom alkalommal egy-egy mesét kaptak, majd egy, a mesékhez kapcsolódó feladatlapot kellett megoldaniuk. Első alkalommal a gyerekek a kapott szöveget maguknál tarthatták, belenézhettek a feladatlap megoldása közben. Második alkalommal a feladatlap megoldása előtt vissza kellett adniuk a szöveget. Harmadik alkalommal pedig az adott szöveget a bemutató olvasás módszerének a segítségével hallgatták meg. A tanulmány azt vizsgálja, milyen összefüggések vannak a három felmérés eredményei között.
Az iskolai mondatelemzés: helyzetkép és problémafelvetés
Authors: Imrényi András
Published: May 2022

A cikk a mondatelemzés kommunikatív kontextusba való beágyazásának és a kategóriák jelentéstani megalapozásának a szükségessége mellett érvel funkcionális kognitív kiindulópontból, de egyúttal az anyanyelv-pedagógia célrendszerére is tekintettel. Felhívja a figyelmet a rendszermondat-nyilatkozat megkülönböztetés és a jelentéstől független elemzési eljárások káros következményeire. Tárgyal továbbá egy olyan, az állandósult szókapcsolatok elemzését érintő problémát, amely a magyartanításban látens maradhat ugyan (azáltal, ha e problematikus jelenség elemzése be sem kerül a tananyagba), de a nyelvészeti továbbgondolkodás igényét veti fel.
Team Approach: Management of Geriatric Acetabular Fractures
Authors: Villacres Mori Benjamin , Young Joseph R. , Lakra Akshay , Chisena Ernest
Published: May 2022

» Geriatric acetabular fractures are defined as fractures sustained by patients who are ≥60 years old. With the rapidly aging American populace and its increasingly active lifestyle, the prevalence of these injuries will continue to increase.

» An interdisciplinary approach is necessary to ensure successful outcomes. This begins in the emergency department with hemodynamic stabilization, diagnosis of the fracture, identification of comorbidities and concomitant injuries, as well as early consultation with the orthopaedic surgery service. This multifaceted approach is continued when patients are admitted, and trauma surgery, geriatrics, and cardiology teams are consulted. These teams are responsible for the optimization of complex medical conditions and risk stratification prior to operative intervention.

» Treatment varies depending on a patient’s preinjury functional status, the characteristics of the fracture, and the patient’s ability to withstand surgery. Nonoperative management is recommended for patients with minimally displaced fractures who cannot tolerate the physiologic stress of surgery. Percutaneous fixation is a treatment option most suited for patients with minimally displaced fractures who are at risk for displacing the fracture or are having difficulty mobilizing because of pain. Open reduction and internal fixation is recommended for patients with displaced acetabular fractures who are medically fit for surgery and have a displaced fracture pattern that would do poorly without operative intervention. Fixation in combination with arthroplasty can be done acutely or in delayed fashion. Acute fixation combined with arthroplasty benefits patients who have poorer bone quality and fracture characteristics that make healing unlikely. Delayed arthroplasty is recommended for patients who have had failure of nonoperative management, have a fracture pattern that is not favorable to primary total hip arthroplasty, or have developed posttraumatic arthritis.

Published: May 2022

US Army Corps of Engineers (USACE) deep-draft navigation economic analyses use assumptions about the sensitivity of vessel operations to channel modification to estimate national economic development benefits. The complexity and proprietary nature of carrier deployment decisions and loading practices adds uncertainty to USACE navigation studies. This report attempts to provide an overview of containership deployment and loading practices as it relates to USACE navigation studies to improve the quality of deep-draft economics. The report relies on trade data, vessel order books, and carrier interviews to study the impact of channel modification on vessel loading and deployment. The report makes recommendations for developing deployment and loading inputs for future economic evaluations.
An Experimental Study on Stress Relaxation of Yunnan Sandstone
Authors: Li Shuai , Zheng Chao , Li Peng
Published: May 2022

This study presents the results from five relaxation tests conducted under uniaxial compression at room temperature. Test specimens were from sandstone formations at a mine, in Yunnan, and exhibited brittle failure. The test apparatus was valid for conducting stress relaxation experiments on sandstones by theoretical model and deformation measurements. Multiple load levels were applied in steps to each specimen, with each displacement level maintained for 12 d or longer. As soon as axial stress was decreased, it stabilized at an almost constant value after 12–24 h. Three distinct relaxation phases were observed to exist at all displacement levels except the specimen 3 in all tests. Based on the LM-NLSF method, model parameters under different strain levels were obtained. Comparison of test curves with theoretical curves showed that the Burgers model, which considers damage, was suitable for describing the stress relaxation properties of sandstones and the obtained parameters had a certain practical value.
