For decades, the Democratic Republic of the Congo (DRC) has been vulnerable to disasters. The most dangerous Nyiragongo volcanic eruption posed a threat to the country, particularly the city of Goma. The explosions on 22 May 2021 caused unfathomable damages, with loss of lives, properties, and the destruction of homes, displacing thousands of people, with thousands of children being left vulnerable as a result. Furthermore, it charred health and school infrastructures and decimated crops, an issue in the population where the COVID-19 has exacerbated the existing fragile health system. Importantly, these eruptions posed a challenge when DRC struggled to end COVID-19 and Ebola through surveillance, preventive measures, and vaccination. It is doubtless that priorities of the emergency have interrupted the surveillance system, thus increasing exposure to the COVID-19 and Ebola transmission. It is critical to provide basic needs to victims of the Nyiragongo volcanic eruptions in the aftermath of such a disaster. Local and global humanitarian organizations are needed to assist residents in relocating. Furthermore, appropriate and adjusted mitigation strategies will significantly prevent Ebola, COVID-19, and other infectious diseases. In this paper, we discuss the impacts of the volcanic eruption on population health and Ebola preparedness and response in the context of the global COVID-19 outbreak in the Democratic Republic of the Congo.
Bir Öfkenin Sürgün Ettiği Poetika: Sarı Lâle
Authors: Şamlıoğlu Kemal
Published: April 2022

Çağdaş Türk şiirinde gerek imge yapısı gerekse üslup olarak İsmet Özel poetikasının en temel özelliği dinamik söz varlığıyla olaylara yaklaşmasıdır. Bu bağlamda Özel’in şiir dilini oluşturan imgelerin de anlam itibariyle sabit yerleşmişlikler içinde kontrol edilemez bir özellik gösterdiği söylenebilir. Şiirinde bu durum anlık olarak imgelerle görülürken benzeşmezlik yönü de bağımsızlığı belirgin şekilde ortaya koyar. Benzerliğe izin vermeyen ve anlam bölünmelerine karşı dirençli olan İsmet Özel poetikası; gezgin, seyyar ve sürgün bir arayışın ürünü olarak asal bir mana boyutuyla uzlaşmama ve çatışma perspektifleri açığa çıkarır. Elbette bu sürgün ve gezgin hâli, iki şekilde düşünülebilir. Birincisi şairin bireysel farkındalığının ve yaratılış özelliklerinin getirdiği mizaç; başka bir ifadeyle bu mizacın getirdiği isyan hâlinin şiir dilinde kendisine yer bulmasıdır. İkincisi ise tarih, iktidar ve toplum merkezli anlam ve eylem biçimlerinin şairin iç dünyasıyla mutlak bir uyumsuzluk hâli göstermesidir. Dolayısıyla bu makale İsmet Özel poetikasının neden kaçış, ayrılış ve terk ediş eksenli bir isyan mücadelesi verdiğinin felsefî ve ontolojik temellerini sorgulamayı amaç edinir.
Modern Ulus Devletin İdeolojik Bir Aygıtı Olarak Eğitim ve 19. Yüzyıl Osmanlı Eğitim Sistemi
Authors: Tekin Yusuf
Published: April 2022

Eğitim, modern devletin ortaya çıkış sürecinden itibaren siyasal iktidarlar tarafından araçsallaştırılan bir nitelik kazanmaya başlamış ve yurttaşların biçimlendirilmesine dönük ideolojik bir işlev üstlenmiştir. Bu süreçte, her eğitim sistemi, bilgi ve hüner aktarımının yanı sıra, ait olduğu evrenin değerler sistemini taşıyan, kültür ve ideoloji transferini gerçekleştiren bir işlevsellikle devlet ideolojisinin oluşması, düzenlenmesi ve yayılması için hizmet gören bir araca dönüşmüştür. Ulus-devletlerin yükselmesiyle beraber kendisini hissettiren bu ideolojik araçsallaştırma süreci Osmanlı Devleti’nde ise nispeten daha geç bir dönemde başlamıştır. Bu çalışmada, 19. yüzyıl Osmanlısından başlayarak Cumhuriyetin ilk yıllarını da kapsayacak şekilde eğitim sistemine odaklanan bir bakış açısıyla, eğitim olgusunun gelenekselden moderne doğru evrilen dönüşüm süreci eleştirel ve tarihsel bir bağlam içinde analiz edilmiş, devletin eğitim aracılığıyla birey ve toplumla kurduğu didaktik ve biçimlendirici ilişkinin incelenmesi amaçlanmıştır. Bu amaç dâhilinde ilk etapta eğitim ve ideoloji arasındaki ilişkiye değinilmiş ve böylelikle çalışmanın teorik çerçevesi çizilmiştir. Ardından ise, Osmanlı arşiv belgeleri ve ilgili literatürden yararlanılarak 19. Yüzyıl Osmanlısından Cumhuriyetin ilk evresine Türkiye’deki eğitim ideoloji ilişkisi mercek altına alınmıştır.

Published: April 2022

Bu çalışmada GG-25 dökme demir iki farklı üretim yöntemi ile üretilerek, mikroyapı ve mekanik özelliklerine döküm yönteminin etkisinin belirlenmesi amaçlanmıştır. Aynı döküm sıcaklığı ve kimyasal kompozisyona sahip GG-25 dökme demir savurma ve kum kalıba döküm yöntemi ile üretilmiştir. Mekanik özelliklerin belirlenmesi için her iki yöntem ile üretilen numunelere çekme deneyi ve Brinell sertlik testleri uygulanmıştır. Çekme deneyi için TS EN ISO 6892-1 standartlarına uygun olarak çekme deney numuneleri üretilmiştir. Mikro yapı analizi optik mikroskop kullanılarak gerçekleştirilmiştir. Savurma döküm yöntemi ile üretilen numunelerin çekme dayanım değeri ortalama 282 MPa olarak elde edilmiştir. Yapılan test ve analizler sonucunda savurma döküm yöntemi ile üretilen parçaların sertlik ve çekme dayanım değerlerinin kum kalıba döküm yöntemi ile üretilen parçalardan daha yüksek olduğu tespit edilmiştir. Mekanik özelliklerin soğuma hızının daha yüksek olduğu savurma döküm yöntemi ile arttığı gözlemlenmiştir. Mikro yapı incelemesinde her iki yöntemle üretilen numunelerin baskın bir şekilde perlitik yapıda olduğu görülmüştür. İki farklı yöntem ile üretilen numunelerin mikro yapı karşılaştırmalarında benzer yapılar elde edilmesine rağmen savurma dökümde homojen yapılı grafit lamellerin sayısına ve lameller arasındaki mesafenin az olmasına bağlı olarak mekanik özelliklerin olumlu yönde değiştiği mikro yapı görüntüleri ve sertlik değerleri ile desteklenmiştir.
The time memory of the Venus flytrap (Dionaea muscipula Ellis)
Authors: Molis Arne , Patten Gabriel , Weidner Manfred
Published: April 2022

For closure to occur, the trap leaves of the carnivorous Venus flytrap (Dionaea muscipula Ellis) normally must be stimulated twice. This is achieved by touching the bending-sensitive hairs protruding from the upper leaf surface. This triggers a rapid thigmonastic capture movement of the leaf lobes. This way incidental closure movements are avoided. The maximal memory time, i.e. the time limit between the first and the second stimulation event, which must not be exceeded, is highly variable and ranges between 20-80 s. Our investigation explores the influences of external (environmental) and internal (plant specific) factors on this memory time. Throughout in this study, a '50%-closure-value' was determined for each variable on basis of 50-100 independent measurements. The memory effect exhibits inverse and sigmoidal temperature characteristics, thus showing a maximum memory time at lower temperatures (15°C). Moreover, the daily photon fluency, the age of the trap leaves, seasonality (the time of leaf emergence), and the recovery time between consecutive stimulation cycles, all affect the time memory strongly. Further, the topology of stimulation also exerts a large influence: The time memory fades more rapidly when two different trigger hairs were stimulated successively within the time limits of the memory instead of touching the same hair twice.

School adaptation in the discourse of fourth graders and their parents
Authors: Kupiec Monika , Rosłoniec Małgorzata
Published: March 2022

The article describes the model of school adaptation adopted by fourth graders and their parents, which translates to a large extent into the perception and evaluation of one's own role in it, and thus sets the framework for activity, in accordance with the adopted constructivist perspective. The phenomenographic perspective of the analysis of data from semi-structured interviews with fourth graders younger by a year and their parents revealed how the respondents describe school adaptation and how they value their own role in it. The ways of thinking about school adaptation and the role of both of its subjects have been interpreted as discursive knowledge. Based on the theory of reproduction an attempt was made to describe the mechanism of consolidating a specific way of perception of school adaptation on the second educational level. The presented research results show that perceiving adaptation as a difficult, fearful process in which parents are responsible for the functioning of fourth graders as pupils is socially acceptable and obvious.

Apesar de ser uma das principais aplicações distribuídas na atualidade, o compartilhamento de arquivos P2P tem sido fortemente prejudicado por ataques de poluição de conteúdo. Em um trabalho anterior, apresentamos uma estratégia de contenção de poluição que consiste em controlar a taxa na qual um conteúdo é disseminado. A taxa de disseminação de uma versão é determinada de acordo com a sua reputação e assegurada através de um mecanismo de autorização. Neste artigo, aperfeiçoamos o esquema anterior e avaliamos por simulação quatro mecanismos distribuídos que implementam a estratégia de contenção. Os resultados mostram que a estratégia é eficaz para ambos os casos de versões poluídas e não-poluídas, causando uma pequena penalidade, mesmo com ataques em conluio de uma parcela significativa de pares maliciosos. Os resultados das simulações obtidos usando configurações realísticas indicam que o mecanismo de contenção de poluição pode efetivamente reduzir a poluição a um baixo custo.

In this study, we aimed to determine the in vitro activity of Leuconostoc mesenteroides var. mesenteroides isolatedfrom sugar-industry effluents to produce a dextran bioflocculant from sucrose as a low-cost substrate.L. mesenteroides strains present in residual cane juice from a sugar factory were isolated and biochemicallyidentified using Mayeux, Sandine, and Elliker agar (MSE) as a selective medium. The strain number 3 (LM03) wasbiochemically identified as L. mesenteroides var. mesenteroides, which was used for this study. The concentrationof dextran was quantified by dry weight, the morphology and purity were evaluated using Fourier-transforminfrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy(EDS). Flocculation was evaluated via turbidimetric assays in different pH ranges from sugar-industry effluentsand doses of dextran.To evaluate the flocculant activity according to the effect of pH, a jar test kit from Phipps and Bird, USA, wasused with the sample recollected from the effluent (sugar industry). The pH of the samples was adjusted to 7, 8,9, 10 and 11, with a dose of 40 ppm (dextran dose) at a fast and slow speed of 150 and 50 rpm, respectively. Toevaluate the influence of the dose of dextran, values of 5, 20 and 40 ppm were used with fast speeds of 180–150rpm and slow speeds of 30–50 rpm, respectively.The strain (LM03) was able to produce the highest concentration of dextran (26.87 g/L) in 76 h of incubation. Thepresence of dextran was identified in the MSE agar after incubation and characterized by FTIR, SEM, and EDS.Besides that, we observed that the best flocculation activity was observed at a pH of 9 and a concentration of 40ppm of dextran, with a fast agitation speed of 150 rpm for 5 min and a slow agitation speed of 50 rpm for 15 min,achieving 77.7% removal of turbidity from the sugar factory effluent.L. mesenteroides was responsible for the bioflocculation of dextran in different sugar-industry effluents
Walkable Urban Environment: Sensory Experiencing in Bechar City (Algeria)
Authors: Ziani Abdelouahab , Biara Ratiba Wided
Published: April 2022

Walkability is becoming one of the central themes in urban research. It is among concerns of city’s designers. Several studies have shown that walking in the city preserves the environment and people’s health. Walkers merge into the city in a total, i.e., effective, sensory, cultural, etc. They perceive the city with their senses. So then, the urban morphology of the street as well as the architecture of the buildings that delimit them influence the sensory perception of the pedestrian. On the other hand, another notion having a considerable development in the last decades is the urban atmosphere. It highlights the other sensory dimensions (thermal, sound, olfactory, tactile, etc.) of the urban space and goes beyond its visual aspect. This research aims to study the walkability in one of the most frequented streets by pedestrians in Bechar city (south of Algeria). Its main objectiveis to know how walkers perceive the urban environment of the street by focusing on their sensory experience. It combines two notions: walkability and atmospheres in the urban space. We used several research techniques: morphological and sensory analysis of the street, participant observation, photo-elicitation interview and survey. The research results attest that there is a strong relationship between the urban environment of the city and walkability. The components of the street such as dimensions, architecture of the buildings that limit it and the prevailing atmospheres have a direct impact on walking in the city and sensory perception of pedestrians. Then, this research is not limited to the visual aspect of urban environment of the street but it emphasizes other sensory dimensions which are often neglected by architects and urban designers of Bechar city.

This work was conducted to evaluate the efficiency of the acerola (Malpighia emarginata) core as adsorbent (ACB) and as a precursor of adsorbent charcoal (CAB) and activated charcoal (ACP), to remove the textile dye remazol golden yellow (RGY) in solution. The adsorbents characterization was obtained by Fourier-transform infrared spectroscopy, thermogravimetric analysis (TG) and determination of the specific area and the point of zero charge (pHpzc). The best conditions for adsorption for this adsorbent was reached through adsorbent mass studies and kinetic and equilibrium assays. The adsorption capacity q (mg.g-1) was used to analyze the effects. The pHpzc were 4.15 for ACB, 6.00 for CAB and 4.32 for ACP, demonstrating superficial charge favorable to dye adsorption. Considering the kinetic aspects, the pseudo-first order model adjusted more satisfactorily to experimental data. Related to isotherms, Langmuir was more efficient to represent experimental data of dye adsorption. ACB, CAB and ACP are potential adsorbents for dyes in effluents, presenting maximum adsorption capacity, in the study conditions, of 52.35 mg.g-1, 16.40 mg.g-1, and 119.00 mg.g-1, respectively.

Published: March 2022

O artigo trata sobre uma produção poética em arte contemporânea onde os métodos participativos e colaborativos foram a base de um processo, que resultou em obras coletivas. A proposta se construiu a partir a partir do “Projeto Artístico Malas Gigantes”, onde o Mala, que é um colar com 108 contas utilizado em práticas de meditação budistas, foi produzido em grandes dimensões a partir de contas feitas de cerâmica com cerca de 7 cm de diâmetro, chegando a atingir aproximadamente de 6 a 8 metros de extensão quando montado. Ao longo do projeto a relação entre arte, espiritualidade, budismo e cerâmica onde o fazer manual e a presença mental se transformou em uma prática meditativa que, ao final, gerou um símbolo de coletividade onde as esferas feitas individualmente se conectaram através de um fio dando nascimento aos Malas Gigantes. Partimos de um oferecimento de aulas, onde técnicas de cerâmica e reflexões com base no budismo eram transmitidas via YouTube; cada participante se conectava e produzia suas esferas individualmente conforme a sua motivação; não havia um número ou meta a ser atingida, e sim, um convite para praticar. Este processo aconteceu junto com o período de isolamento social em função da pandemia da covid-19, iniciando em maio de 2020. Ele teve um tempo expandido para que muitas esferas pudessem ser feitas. Em outubro de 2021 tivemos as condições que possibilitaram a reunião de um grupo para a execução das montagens dos Malas e realização de instalações coletivas.
Guiding students’ attention towards multiplicative relations around them: A classroom intervention
Authors: Määttä Saku , Hannula-Sormunen Minna , Halme Hilma , McMullen Jake
Published: March 2022

Learning fractions poses a challenge for many elementary school students, including applying fraction knowledge in novel contexts. For instance, there are substantial individual differences in students’ tendency of spontaneous focusing on quantitative relations (SFOR), which is related to the development of rational number knowledge. In this study, 4th grade students (N = 129) took part in a quasi-experimental study comparing an intervention condition (n = 71) aimed at improving students’ multiplicative relational reasoning and fraction knowledge with a control condition (n = 58) of business as usual fraction instruction. Five lessons of intervention activities were designed to promote students ability to recognize and describe multiplicative relations in their everyday surroundings. There was an overall positive effect on the students’ mathematical knowledge. Students who participated in the intervention improved their ability to recognize and describe multiplicative relations embedded in pictures representing everyday situations. There were no significant differences in the development of fraction knowledge despite replacing five traditional fraction lessons. These findings provide further evidence that researchers and educators should continue to pay attention to issues surrounding students’ spontaneous mathematical focusing tendencies.

Authors: Martínez de Miguel Pablo , García Martínez Antón , Montes-Botella José-Luis
Published: March 2022

Objective: The objective of the paper is to identify relations between digital transformation and the micro-foundations of the dynamic capabilities within the automotive sector.Methodology: To achieve the previous goal, the analysis is based on a literature review and expert judgments through a survey. Then, from a quantitative methodology of exploratory analysis the correct assignment of the indicators as well as a SEM analysis of structural equations with latent variables as a statistical technique has been used.

Results: Therefore, using the indicators already presented, it has been possible to establish the relationship model. We have been able to present how all these indicators correspond to dynamic capabilities, and it is the digital transformations that generate them.

Limitations: the research presents some limitations that should be considered when contextualizing the work done. The most representative one is the difficulty of obtaining a larger sample, because out of 142 surveys, only 42 responses were obtained, due to the limited time respondents had to attend to the researcher.Practical implications: the automotive industry is continuously impacted with the introduction of new technologies, which makes it necessary for organizations to adapt to the fast pace of growth. Furthermore, companies that understand the importance of digital transformation show more modern work styles, consider user preferences and the information they can obtain from the context.

Published: April 2022

The quantum nonlocal correlation of quantum states plays an important role in the quantum information and quantum computing protocols. However, during the transmission of entangled states in the quantum channel, they will inevitably interact with the environment, resulting in the degradation of the coherence and then weakening the quantum nonlocal correlation. Using a high probability quantum nonlocal correlation testing scheme based on Hardy-type paradox, in this paper we investigate the quantum nonlocal correlation testing of two-qubit polarization entangled states when they transmit through amplitude damping channel (ADC), phase damping channel (PDC) and depolarization damping channel (DC). The results show that DC has a great influence on the quantum nonlocal correlation testing, while PDC has little influence on the quantum nonlocal correlation testing of quantum states. Finally, this paper also gives condition for the successful quantum nonlocal correlation testing of ADC under weak measurement and quantum weak measurement reversal operation. The results show that when the intensity of weak measurement increases, the influence of ADC decoherence effect on quantum nonlocal correlation testing can be effectively reduced.

In the era of The Internet of Things, how to develop a smart sensor system with sustainable power supply, easy deployment and flexible use has become an urgent problem to be solved. Triboelectric nanogenerator (TENG) driven by Maxwell’s Displacement Current can convert mechanical motion into electrical signals, thus it can be used as a self-powered sensor. Sensors based on TENGs have the advantages of simple structure and high instantaneous power density, which provide an important means to build intelligent sensor systems. Meanwhile, machine learning, as a technique with low cost, short development cycle, and strong data processing capabilities and predictive capabilities, is effective in processing the large amount of electrical signals generated by TENG. This article combines the latest research progress of TENG-based sensor systems for signal processing and intelligent recognition by employing machine learning techniques, and outlines the technical features and research status of this research direction from the perspectives of traffic safety, environmental monitor, information security, human-computer interaction and health motion detection. Finally, this article also in-depth discusses the current challenges and future development trends in this field, and analyzes how to improve in the future to open up a broader application space. It is suggested that the integration of machine learning technology and TENG-based sensors will promote the rapid development of intelligent sensor networks in the future.

Using non-equilibrium Green's function combined with density functional theory, we investigate the spin-resolved transport properties of the zigzag SiC nanoribbon (zSiCNR) connecting anthradithiophene (ADT) molecules and obtain the giant spin current rectification in the presence of a ferromagnetic field. The dual-hydrogenation on edge C atoms or Si atoms can change the initial metallicity of the pristine zSiCNR with the edge mono-hydrogenation into semiconductivity in the presence of a ferromagnetic field. The up-spin current-voltage characteristic of the cis-ADT device and the trans-ADT device can present the significant rectification, and the corresponding giant spin current rectification ratios are close to 1011 and 1010 respectively. In addition, the current-voltage characteristics of two devices both perform a perfect spin filtering behavior in the positive bias region due to the huge difference between the up-spin current value and the down-spin current value. These findings are of great significance in the functional applications of spin-resolved molecular devices in the future.

We compare the results obtained by self-consistent relations of Bethe lattice and squate lattice based on DMFT procedure, and the general OSMP physics of Bethe lattice is consistent with that of the square lattice while the critical points of two kinds of lattices are different. We extend the method to the study of half-filled Ba2CuO4–δ materials. By comparing with the band structure obtained from the density functional theory (DFT), it is found that the isotropic inter-orbital hopping has a great influence on the bandstructure. The DFT bandstructure in DMFT is considered, and the phase diagram of the material is obtained. The half-filled Ba2CuO4–δ should be orbital-selective Mott compound according to our results.

Type IIa receptor-like protein tyrosine phosphatases (RPTPs) are essential for neural development. They have cell adhesion molecule (CAM)-like extracellular domains that interact with cell-surface ligands and coreceptors. We identified the immunoglobulin superfamily CAM Sticks and Stones (Sns) as a new partner for the Drosophila Type IIa RPTP Lar. Lar and Sns bind to each other in embryos and in vitro, and the human Sns ortholog, Nephrin, binds to human Type IIa RPTPs. Genetic analysis shows that Lar and Sns function together to regulate larval neuromuscular junction development, axon guidance in the mushroom body (MB), and innervation of the optic lobe (OL) medulla by R7 photoreceptors. In the neuromuscular system, Lar and Sns are both required in motor neurons, and may function as coreceptors. In the MB and OL, however, the relevant Lar-Sns interactions are in trans (between neurons), so Sns functions as a Lar ligand in these systems.

Insects adapt their response to stimuli, such as odours, according to their pairing with positive or negative reinforcements, such as sugar or shock. Recent electrophysiological and imaging findings in Drosophila melanogaster allow detailed examination of the neural mechanisms supporting the acquisition, forgetting, and assimilation of memories. We propose that this data can be explained by the combination of a dopaminergic plasticity rule that supports a variety of synaptic strength change phenomena, and a circuit structure (derived from neuroanatomy) between dopaminergic and output neurons that creates different roles for specific neurons. Computational modelling shows that this circuit allows for rapid memory acquisition, transfer from short term to long term, and exploration/exploitation trade-off. The model can reproduce the observed changes in the activity of each of the identified neurons in conditioning paradigms and can be used for flexible behavioural control.

The morphology of the pectoral girdle, the skeletal structure connecting the wing to the body, is a key determinant of flight capability, but in some respects is poorly known among stem birds. Here, the pectoral girdles of the Early Cretaceous birds Sapeornis and Piscivorenantiornis are reconstructed for the first time based on computed tomography and three-dimensional visualization, revealing key morphological details that are important for our understanding of early-flight evolution. Sapeornis exhibits a double articulation system (widely present in non-enantiornithine pennaraptoran theropods including crown birds), which involves, alongside the main scapula-coracoid joint, a small subsidiary joint, though variation exists with respect to the shape and size of the main and subsidiary articular contacts in non-enantiornithine pennaraptorans. This double articulation system contrasts with Piscivorenantiornis in which a spatially restricted scapula-coracoid joint is formed by a single set of opposing articular surfaces, a feature also present in other members of Enantiornithines, a major clade of stem birds known only from the Cretaceous. The unique single articulation system may reflect correspondingly unique flight behavior in enantiornithine birds, but this hypothesis requires further investigation from a functional perspective. Our renderings indicate that both Sapeornis and Piscivorenantiornis had a partially closed triosseal canal (a passage for muscle tendon that plays a key role in raising the wing), and our study suggests that this type of triosseal canal occurred in all known non-euornithine birds except Archaeopteryx, representing a transitional stage in flight apparatus evolution before the appearance of a fully closed bony triosseal canal as in modern birds. Our study reveals additional lineage-specific variations in pectoral girdle anatomy, as well as significant modification of the pectoral girdle along the line to crown birds. These modifications produced diverse pectoral girdle morphologies among Mesozoic birds, which allowed a commensurate range of capability levels and styles to emerge during the early evolution of flight.

Coronavirus pandemic created havoc on our planet, affecting all aspects of human life. It has resulted in human mortality and morbidity worldwide. It did not spare social and economic fabric of societies. It has resulted in huge psychosocial impact on human race. Various disease containment measures such as quarantine, physical distancing, complete lockdowns imposed by governments across the globe has severely affected mental health of children and adolescents. This paper is aimed at reviewing various articles published regarding the Coronavirus Disease 2019 (COVID-19) pandemic impact on mental health of children with or without previous mental health problems. Different electronic databases, such as Science Direct, PubMed and Google Scholar were searched for articles describing impact on mental health of children and adolescents with/without previous mental health problems due to COVID-19. Search strategies included terms such as: “COVID-19”, “SARS-CoV-2”, “mental health”, “children”, “adolescent”, “behavioural impact”, “depression” and “anxiety.” The majority of children and adolescents experienced deterioration in their mental health as emergency measures were implemented throughout the world. Children diagnosed with preexisting mental health problems or Autism Spectrum Disorder (ASD) experienced more negative changes compared with children/ adolescents without pre-existing psychiatric diagnoses. There is increased anxiety, depression, irritability, sleep disorders, lethargy, dissatisfaction and fear of death. There is need to plan and implement strategies to provide easy and early access to mental health services for which various stakeholders should come together.

Autism is a life-long neurodevelopmental disorder. Children with autism find it difficult to focus their attention, memorize, think and develop social skills compared to their peers. A recent report reveals that currently one in 500 people in India have autism and there is an increase in the prevalence of cases in the past few years. Autism is a serious health issue and should not be overlooked. It is important to create awareness among people to promote better understanding and knowledge of autism. In India, autism has been considered as one of the disabilities under section 2 of the National Trust Act, 1999. There is an increased need to develop evidence-based services in various sectors such as medical, educational, and social. This will be beneficial to minimize the existing gap between children with autism and those who are normal by birth. This review focuses on the various learning tools developed to help children with autism studying in special schools in India. Here, we have revealed the role of technology advancement in building attention, improving social skills, developing verbal communication and flexible thinking in children with autism in India.

Published: April 2022

Creating stated, realistic educational objectives is a vital component of establishing corporate training programs. Both management and instructors must agree on what learners should understand after completing their learning path. Learning objectives are also significant in evaluation and assessment since they indicate what information students should have when the teaching process is completed. Several scholars revealed that the instructor's promptness appears to be a critical factor in developing interpersonal relationships with students and increasing student communication and learning results in Saudi Arabian colleges. Users of e-learning technologies in the Kingdom of Saudi Arabia are dissatisfied. Students are not disappointed with the IT infrastructure or other technological characteristics. Many students, on the other hand, report minimal interaction with their peers. When contacts do occur, students find them to be quite useful.

The first half of the twentieth century was a time of great trials for all Eastern countries, especially for the Korean Peninsula, which stood on the verge of a “new world”, following the news of a new era, the creation of new schools. By this time, Westernization reforms under the influence of neighboring Japan, which attracted the attention of powerful states, were gaining momentum. As a result of Japan’s efforts to westernize and reform the “Year of the Kabo”, a new culture, politics, literature, Japanese customs and traditions have entered the country. It is known from history that during the colonization of any state, first of all, a serious blow is inflicted on its culture, language, beliefs, national pride. Using such an effective method, the Japanese government pursued a colonial policy aimed at destroying the national spirit and culture of the Korean people.
