STATEMENT OF THE NATIONAL ACADEMY OF EDUCATIONAL SCIENCES OF UKRAINE
Authors:   National Academy of Educational Sciences of Ukraine
Published: February 2022

We consider it criminal and strongly condemn the violation of the territorial integrity and borders of Ukraine by the Russian Federation. We also consider inadmissible the statements of the leadership of the Russian Federation regarding our state, interference in the internal affairs of Ukraine by denying its civilizational subjectivity and demanding the abandonment of its own path of development. With great gratitude and confidence in the victory, we turn to the defenders of Ukraine: we are together, we are convinced of the strength and steadfastness of those who defend Democracy, Freedom, and Human Values! Resistance is not just military resistance. The opposition of every citizen is not to succumb to provocations and panic, to prevent escalation of tensions, to refute fakes, to maintain clarity of thinking. A patriot is someone who invests in the development of the country and preserves its defense capabilities in a way accessible to him. For representatives of pedagogical and psychological sciences — is to maintain the national identity and unity of the nation at the level of consciousness of every citizen, territorial community, society. This is the strengthening of the subjectivity of every citizen through his awareness of Ukrainian history from the times of Kyivan Rus, Ukrainian mentality of freedom from the Cossack era, the spirit of Ukrainian democracy from the Constitution of Philip Orlyk, invincibility of the Ukrainian army from the victories of Peter Konashevych-Sahaidachnyi and Bohdan Khmelnytskyi, exercise of self-awareness by Hryhorii Skovoroda and Taras Shevchenko. Scientists of the National Academy of Educational Sciences of Ukraine, as always, are ready for a dialogue with anyone who finds himself in difficult life circumstances, in situations of confusion or uncertainty, who needs advice or psychological help. We all have hard work ahead of us every day. But our goal is common and high — to preserve the sovereignty and territorial integrity of Ukraine. To this end, we have worked for Ukraine′s independence, we have also worked for the development of our state for the last 30 years, for this, we are mobilizing for further struggle! We will win! Glory to Ukraine!
METODE AMINA WADUD DALAM PENAFSIRAN ALQURAN
Authors: Zabidi Ahmad
Published: February 2022

Amina Wadud dalam pengantar salah satu bukunya, “Qur’an Menurut Perempuan: Membaca Kembali Kitab Suci dengan Semangat Keadilan”, menyatakan bahwa bukan tentang teks al-Qur’an yang membatasi perempuan, melainkan penafsiran terhadap teks teks keagamaan itulah yang membatasinya yang dianggap lebih penting dari pada al-Qur’an sendiri. Amina juga mengungkapkan bahwa arti penting analisis tentang konsep al-Qur’an tentang perempuan, harus diukur dari perspektif al-Qur’an sendiri, baik sebagai kekuatan dalam sejarah, politik, bahasa, budaya, kecendekiawanan, dan spiritualitas, maupun sebagai kitab suci. Kajian tentang metode Amina Wadud Muhsin dalam memahami ayat-ayat al-Qur'an berupaya menafsirkan ulang berbagai ayat al-Qur’an yang selama ini cenderung ditafsirkan secara patriarkhis oleh para mufasir klasik, maka metode yang digunakan dalam penafsiran al-Qur’an menggunakan  pendekatan holistik.

Published: February 2022

Penentuan awal bulan Ramadhan atau penentuan 1 Syawal kerap kali terjadi perbedaan, yang mengakibatkan tidak serentaknya puasa Ramadhan dan hari raya idul fitri termasuk di sebuah daerah wilayah Aceh Singkil tepatnya di desa Tanjung Mas, disana sering kali lebih dahulu melaksnakan puasa Ramadhan dibandingkan dengan desa lainnya. Tujuan dalam pembahasan ini untuk menjelaskan bagaimaana penetapan awal bulan Ramadhan dan penentuan hari raya idul fitri di desa Tanjung Mas. Penelitian ini menggunakan metode kualitatif dengan pendekatan sosiologis, data diambil dari hasil wawancara yang mendalam. Hasil penelitian bahwa masyarakat desa Tanjung Mas Kecamatan Simpang Kanan Kabupaten Aceh Singkil dalam menentukan awal bulan Ramadhan dengan menggunakan metode hisab buang lima, metode ini merupakan sebuah metode dari nenek moyang mereka, termasuk Syekh Abdur Rauf dan Abu Pinto.begitu juga penentuan dengan 1 Syawal, mereka hanya menghitung 30 hari kedepannya, itulah 1 Syawal. Konsep hisab buang lima menganggap bahwa bulan Ramdhan berjumlah 30 hari dan tidak boleh kurang. Metode yang digunakan masyarakat Tanjung Mas berbeda dengan penentuan pemerintah. Penentuan buang lima-lima lebih cepat puasa satu hari dibanding dengan pemerintah.

Published: February 2022

Bitkisel ürünlerden aktif bileşenlerin ekstraksiyon yöntemleriyle elde edilmesi, besin takviyeleri ve farmasötik ilaç endüstrisinin önemli süreçlerindendir. Bitki ekstraksiyonunda elde edilen ürünlerin kalitatif ve kantitatif sonuçları; çözücünün içeriği ve moleküler yapısı, çözünen maddenin içeriği ve hasat zamanı, ortam ısısı ve ekstraksiyonun süresi gibi birçok parametre ile ilişkilidir. Bu çalışmada farklı dönemlerde (çiçeklenme başlangıcından bir hafta sonra=HZ1, çiçeklenme başlangıcından iki hafta sonra=HZ2, çiçeklenme başlangıcından üç hafta sonra=HZ3) hasat edilen aspir bitkisi çiçeklerinin farklı çözücüler (saf su, etanol, metanol ve aseton) kullanılarak ekstraksiyonları yapılmıştır. Üç farklı dönemde hasat edilen aspir çiçeklerine uygulanan farklı çözücülerin çiçeklerdeki toplam antioksidan aktivite (FRAP) ile toplam fenolik ve flavonoid madde miktarları değişimleri belirlenmiştir. Hasat zamanına göre en yüksek toplam fenolik madde miktarı (132.30 mg GA/100g) ile 2. hasat zamanından elde edilirken, en yüksek toplam flavonoid madde miktarı (19.15 mg QE/100g) ve toplam antioksidan aktivite (20.30 mg TE/g) 1. hasat zamanından tespit edilmiştir. Ayrıca, en yüksek toplam flavonoid madde miktarı (32.15 mg QE/100g) metanol ektraksiyonundan, en yüksek fenolik madde miktarı (224.05 mg GA/100g) ve toplam antioksidan aktivite miktarı (61.25 mg TE/g) ise saf su ektraksiyonundan belirlenmiştir. Aspir çiçeklerin çiçeklenme başlangıç dönemlerinde hasat edilmesi ve su ile ekstrakte edilmesi aspir çiçeklerinden maksimum düzeyde faydalanılabilirlik için önem arz etmektedir.

Published: February 2022

Quem pode exercer a Medicina Tradicional Chinesa? A resposta a esta pergunta tem gerado no Brasil diversas inquietações ao longo dos anos. A princípio, a acupuntura era exercida por imigrantes chineses e japoneses em um circulo mais restritos as estas etnias, ocasionando disputas jurídicas na medicina ocidental, pelo Conselho Federal de Medicina – CFM, à mais recente regulamentaçãoexpedida pelo Conselho Federal de Nutrição, em sua resolução CFN nº 681 de 19/01/2021, que foi suspensa por determinação judicial exarada nos autos nº 1012034-72.2021.4.01.3400 pela justiça federal do Distrito Federal. Tais investidas tem partido por outros inúmeros Conselhos, que de maneira direta ou indireta, tentam subjugar a Medicina Tradicional Chinesa, não só as suaspraticas, mas também a suas conglomerações legais. Tais princípios regulamentares, alem de, em muitos casos impor requisitos técnicos que afrontam a constitucionalidade, criam praticas de intervenção em saúde por diversas vezes com interpretação distintas do principio oriental. Assim, se faz necessário definir com clareza a base legal atual, quem e como pode ser praticada a Medicina Tradicional Chinesa e suas ramificações, como auriculoterapia, moxabustão, ventosaterapia entre outras.

Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O- or B-type subdwarf (sdO/sdB), and the mass gainer spins up and grows a disk to become a Be star. While several Be+sdO binaries have been identified, dynamical masses and other fundamental parameters are available only for a single Be+sdO system, limiting the confrontation with binary evolution models. In this work, we present direct interferometric detections of the sdO companions of three Be stars—28 Cyg, V2119 Cyg, and 60 Cyg—all of which were previously found in UV spectra. For two of the three Be+sdO systems, we present first orbits and preliminary dynamical masses of the components, revealing that one of them could be the first identified progenitor of a Be/X-ray binary with a neutron star companion. These results provide new sets of fundamental parameters that are crucially needed to establish the evolutionary status and origin of Be stars.
Neutrino Echos following Black Hole Formation in Core-collapse Supernovae
Authors: Gullin Samuel , O’Connor Evan P. , Wang Jia-Shian , Tseng Jeff
Published: February 2022

During a failed core-collapse supernova, the protoneutron star eventually collapses under its own gravitational field and forms a black hole. This collapse happens quickly, on the dynamical time of the protoneutron star, ≲0.5 ms. During this collapse, barring any excessive rotation, the entire protoneutron star is accreted into the newly formed black hole. The main source of neutrinos is now removed and the signal abruptly shuts off over this formation timescale. However, while the source of neutrinos is turned off, the arrival times at an Earth-based detector will depend on the neutrino path. We show here that a modest amount of neutrinos, emitted just prior to the black hole forming, scatter on the infalling material into our line of sight and arrive after the formation of the black hole, up to 15 ms in our model. This neutrino echo, which we characterize with Monte Carlo simulations and analytic models, has a significantly higher average energy (upwards of ∼50 MeV) compared to the main neutrino signal, and for the canonical failed supernova explored here, is likely detectable in



(10 kT) supernova neutrino detectors for Galactic failed supernovae. The presence of this signal is important to consider if using black hole formation as a time post for triangulation or the post black hole timing profile for neutrino mass measurements. On its own, it can also be used to characterize or constrain the structure and nature of the accretion flow.
“Je serais peut-être pas gay si j’avais pas regardé des pornos gays”. Sexualité minorisée et socialisation de renforcement par les médias
Authors: Pagiusco Maialen
Published: February 2022

Cet article s’intéresse à la façon dont les médias peuvent contribuer à la formation de représentations, de pratiques et d’identifications non hétérosexuelles, en les analysant en termes de socialisation de renforcement. Il s’agit de saisir, de manière empirique, deux dimensions de ces processus de renforcement par les médias, d’abord dans la dynamique des trajectoires, en se concentrant sur l’entrée dans l’homosexualité, puis dans l’emboîtement avec les processus de socialisation par les pairs qui partagent l’expérience d’une sexualité minorisée. Il s’appuie sur une cinquantaine d’entretiens biographiques, sur des observations participantes en associations LGBT+ qui permettent d’intégrer à l’analyse la dimension collective des appropriations médiatiques.
Une agentivité inégalitaire : jeux vidéo et accessibilité des filles à la parole publique
Authors: Vari Judit
Published: February 2022

Les jeux vidéo sont devenus un moyen d’expression et de connaissance privilégié par les jeunes. Ils permettent de développer la prise de parole au sein de la famille, avec les pairs, entre joueurs et créent du lien social. Cet article interroge, à partir d’une analyse de la littérature surtout anglo-saxonne, la façon dont ils participent au processus de démocratisation des sociétés contemporaines en développant l’agentivité (agency) des enfants et adolescents et celle dont les filles peuvent se les approprier. Il discute des freins et limites de ce processus pour les filles. Celles-ci restent peu visibles dans l’espace médiatique et sont bien moins nombreuses dans le eSport. Les harcèlements sexistes les mènent à adopter des stratégies de camouflage –avatar masculin, modification de la voix– ou à abandonner la compétition. L’eSport serait-il un espace de réaffirmation de l’identité et de la domination masculine en maintenant le contrôle de la parole dans un domaine médiatisé ? La parole de la joueuse, sa prise en compte dans l’espace ludique public sont un point aveugle à questionner. Les jeux vidéo et les loisirs, espaces intermédiaires de socialisation, sont trop sous-estimés par les chercheurs, les éducateurs, les politiques, pour comprendre ce qui se joue dans la socialisation enfantine. Des pans entiers de la compréhension des pratiques juvéniles échappent encore et peuvent conduire à des choix contre-productifs sur le plan éducatif.
Tombeau de Claude Debussy de Maurice Ohana : une introduction analytique
Authors: Delaplace Joseph
Published: February 2022

Cet article propose une présentation analytique et esthétique de l’une des œuvres-clés de Maurice Ohana (1913-1992). Tombeau de Claude Debussy est, au début des années 1960, la composition dans laquelle se cristallisent des formes d’écritures qui définissent la signature sonore du compositeur. Corrélativement, la figure de Debussy s’affirme en tant que « père spirituel », et c’est en élaborant certaines potentialités laissées à l’état latent par le maître français qu’Ohana construit sa propre identité stylistique, dont le Tombeau en 1962 et les 12 Études d’interprétation vingt ans plus tard déclinent avec le plus d’évidence cette filiation. Après avoir replacé l’œuvre dans son contexte, cette introduction analytique l’aborde sous l’angle de ses types d’écriture et de son instrumentation, avant d’en examiner les principes formels et le tissu intertextuel, et d’aborder la question de l’énergie et du geste.
Dans les méandres de la psychologie de masse : la mythologie politique du trumpisme
Authors: Bottici Chiara , Bonhoure Véronique
Published: February 2022

Cet essai explore la psychologie de masse du fascisme, en mettant l’accent sur le lien libidinal qui relie les militants fascistes à leur leader. En m’appuyant sur des écrits d’Adorno et de féministes sur la psychologie de masse de Freud, je soutiendrai que le trumpisme repose précisément sur ce type de lien libidinal. Après avoir exploré la mythologie politique sous-jacente des campagnes de Donald Trump, l’article conclut par quelques réflexions sur l’impact des médias sociaux dans la fomentation d’une psychologie de masse potentiellement fasciste et les moyens dont on dispose pour nous engager de manière critique à leur égard.
Le Covid‑19 et les aléas de la démocratie consultative
Authors: Jaeger Marcel
Published: February 2022

La crise provoquée par le Covid‑19 s’est accompagnée d’une mobilisation très forte d’instances, de commissions, de conseils et de hauts conseils…, qui soit ont été saisis par les autorités gouvernementales, soit se sont autosaisis, pour produire des avis et des recommandations de bonnes pratiques. Ce phénomène s’est accompagné d’un décalage entre les instances fonctionnant dans le domaine de la santé publique, bénéficiant d’un encouragement des autorités gouvernementales, et les instances relevant de l’action sociale et médico-sociale. Dans tous les cas, faut-il y voir une opportunité pour renforcer, avec ces instances, les démarches démocratiques ou, au contraire, constater le prolongement d’un fonctionnement bureaucratique sans portée significative ? Autrement dit : démocratie consultative ou administration consultative ?
Les représentations de professionnels d’une association à la suite de la gestion du premier confinement
Authors: Foudriat Michel
Published: February 2022

Cet article présente des réflexions relatives aux effets de la gestion institutionnelle du confinement par une direction générale d’une association départementale. Il montre comment des représentations négatives ont pu se construire très rapidement à la suite des mesures singulières que la direction générale de l’association a prises pour gérer les conséquences du premier confinement. Les établissements du pôle « Hébergement » (foyers, fam et mas ) se sont retrouvés, du fait du confinement des personnes qu’ils accueillent, dans un déficit de professionnels pour maintenir la continuité des activités. Pour pallier ce déficit, une cellule dite de recrutement a été instaurée par la direction générale afin d’affecter des professionnels des établissements du pôle « Accompagnement et insertion » ( ime et esat ) vers les établissements du pôle « Hébergement ». Les modalités effectives avec lesquelles les affectations ont été arrêtées ont généré chez les professionnels des épreuves concrètes qui, pour les uns comme pour les autres, se sont révélées insatisfaisantes. L’article montre en quoi les représentations sur la gestion institutionnelle de la crise sanitaire sont à considérer comme des constructions socio-cognitives contingentes liées aux expériences vécues par les différents professionnels dans le contexte de l’application des mesures du premier confinement.
Covid‑19 : un révélateur du traitement social de la vieillesse
Authors: Amyot Jean-Jacques
Published: February 2022

La crise a révélé des valeurs, des manières de penser et d’agir qui habituellement effleurent à la surface du social. La vieillesse et son portrait schématisé ont généré des réactions agrégées aux deux pôles de l’axe affectif, révélant la relation singulière entretenue avec elle. L’idée d’un confinement déterminé selon l’âge a été portée par des acteurs politiques, des personnalités et la vox populi médiatisée. Considérer les personnes âgées comme un groupe singulier, homogène et dissociable du reste de la société ouvre sur un questionnement éthique, politique et social. Inactivité, inutilité et vulnérabilité seront interrogées. Si toutes les crises conduisent à la crainte de conflits sociaux, l’annonce d’une guerre des générations a joué pleinement ce rôle. Les contraintes et pénuries provoquent des frustrations, des pertes portant atteinte à la qualité de vie et questionnant les modalités d’arbitrage. En situation syndémique, les personnes âgées se sont retrouvées au croisement de deux épidémies, le Covid‑19 et le vieillissement de la population, qui en a toutes les caractéristiques avec ses symptômes bruyants, innommables et innombrables, et sa place entre imaginaire social et réalité contemporaine : la maladie et la mort, la peur, la relégation, l’affrontement, le bouc émissaire…

Stability of international pollution control games: A potential game approach
Authors: Rilwan Jewaidu , Kumam Poom , Hernández-Lerma Onésimo
Published: February 2022

In this paper, stabilization problems for n-player noncooperative differential games of international pollution control (IPC) are analysed via the concept of the potential differential game (PDG) introduced by Fonseca-Morales and Hernández-Lerma (2018). By first identifying a game of IPC as a PDG, an associated optimal control problem (OCP) is obtained, whose optimal solution is a Nash equilibrium (NE) for the game of IPC. Thus, the problem of finding conditions for which the NE stabilizes the game of IPC reduces to finding conditions for which the optimal solution stabilizes the associated OCP. The concept not only yields mild conditions for saddle point stability analysed in the literature but also for the overtaking optimality of the NE of the game of IPC.
Conditions sociales, registres de vulnérabilité et territoires de vie dans la France d’aujourd’hui
Authors: Marchal Hervé
Published: February 2022

L’article entend mettre en évidence des liens analytiques entre des formes de vulnérabilité et des territoires précis. Il s’appuie sur des recherches empiriques menées en France qui portent aussi bien sur des zones résidentielles excentrées du périurbain, sur une tour déshéritée située dans une cité d’habitat social ou sur un bidonville. Les terrains de recherche retenus sont autant de révélateurs des formes plurielles que prend la vulnérabilité dans la société française actuelle. Sensible à la pluralité des sources et des formes de vulnérabilité, le propos s’attache, chemin faisant, à identifier différents registres de vulnérabilité. Parce que ces différents registres en disent long sur l’existence de fortes disparités non seulement spatiales mais aussi sociales, ils renvoient à des conditions sociales distinctes qui révèlent combien la « société » française contemporaine est le théâtre de profondes divergences socio-spatiales.
Vie périurbaine et mobilités quotidiennes : une double contrainte source de difficultés socio-économiques pour les personnes modestes et âgées
Authors: Gateau Matthieu
Published: February 2022

Dans les territoires périurbains, la mobilité et l’automobilité sont indissociables autant qu’indispensables, tant pour les travailleurs transformés en « navetteurs » que pour des populations vieillissantes qui risquent l’isolement et la dépendance. Pourtant, les contraintes économiques des uns et l’impossible mobilité des autres, parfois même au sein de leur logement, rendent leur situation très complexe et les mènent vers une vulnérabilité certaine. À partir de sources et matériaux qualitatifs, ces éléments seront présentés et discutés à travers l’examen, dans de multiples espaces périurbains bourguignons, de la situation de pavillonnaires modestes puis de personnes âgées de moins en moins mobiles… et de plus en plus isolées.
La misère de position automobile : socialisation de classes et rapport social à l’automobile
Authors: Cacciari Joseph , Belton Chevallier Leslie
Published: February 2022

De nombreuses politiques urbaines tentent aujourd’hui de réduire la place de l’automobile au cœur des villes françaises. Si elle peut se révéler variée, l’appréciation de cette incitation « par le haut » est souvent peu analysée du point de vue des ménages, notamment ceux issus des classes populaires, les plus à même d’être vulnérabilisés par l’abandon de la voiture. Dans cet article nous montrerons qu’au-delà de leurs conditions économiques absolues, les rapports des ménages à la voiture rendent compte d’une misère de position qui renvoie à la perception de leur positionnement dans l’espace social et qui est susceptible d’évoluer au gré de leur trajectoire, de leur socialisation. L’argumentation de l’article s’appuie sur une enquête par entretiens biographiques menée dans quatre aires urbaines françaises (Bordeaux, Dijon, Lyon et Paris) auprès de personnes ayant renoncé, par contrainte ou non, à l’usage ou à la possession de véhicule motorisé pour les déplacements quotidiens.
Trajectoires familiales, scolaires et amoureuses : comment les mineurs incarcérés traversent leur jeunesse
Authors: Amsellem-Mainguy Yaëlle , Coquard Benoît , Vuattoux Arthur
Published: February 2022

Quel lien peut-on faire entre les trajectoires des mineurs incarcérés et leurs plus ou moins grandes vulnérabilités face à l’expérience de l’incarcération ? À partir d’une enquête par entretiens auprès des mineurs incarcérés et des professionnels qui les encadrent, l’article étudie les conséquences des ruptures biographiques, scolaires et amoureuses induites par la ou les incarcérations successives. Les jeunes rencontrés affichent sur ces différents aspects des différences notables, liées notamment aux parcours scolaires inégaux. Les « décrocheurs » sont les plus prompts à se situer comme « en dehors » de la jeunesse. Tandis que ceux qui fréquentaient encore l’école au moment de leur incarcération partagent davantage les codes de leur génération et voient plus la prison comme un stade transitoire, qui ne marquera que leur jeunesse, mais pas forcément leur « vie d’adulte ». L’autre thématique abordée dans l’article est celle de l’entrée dans la sexualité. Sur ce point, les jeunes filles et garçons rencontrés sont assez semblables à celles et ceux de leur milieu social. En revanche, l’incarcération est une épreuve dans la gestion de leurs relations amoureuses, amicales et familiales. L’emprisonnement tend à pousser ces jeunes à recomposer leurs attentes en termes de relations amoureuses mais aussi amicales. Plus généralement, cette expérience favorise un rapport aux autres marqués par la suspicion et l’auto-exclusion.
La mobilité résidentielle comme cause et conséquence de vulnérabilité chez les personnes âgées à La Réunion
Authors: Klein Armelle , Sandron Frédéric
Published: February 2022

Sur la base d’une revue de la littérature et d’un corpus de quatorze entretiens semi-directifs, l’objet de cet article est de mettre en relation les facteurs de vulnérabilité du territoire réunionnais, ceux des personnes âgées de ce département français d’outre-mer ainsi que ceux éventuellement issus d’une mobilité résidentielle. Pour cela, une analyse macroscopique et une analyse individuelle sont proposées autour des facteurs de vulnérabilité dans les registres économiques, sanitaires, sociaux et environnementaux. Ces deux niveaux d’analyse indiquent la nécessité d’une approche territoriale fine pour mieux comprendre la vulnérabilité des personnes âgées et ses liens avec la mobilité résidentielle.
Habitual locomotor types and the shape of lower leg bones in primates, especially in hominoids
Authors: Kimura Tasuku
Published: February 2022

The mechanical dominance of the hindlimbs compared with the forelimbs in positional behavior in primates has been settled. Among primate hindlimb bones, the femur has received the main focus. The primate lower leg bones have not been studied precisely in relation to locomotor behavior. In this study, the lower leg bones of primates, 316 individuals in 80 species and 47 genera, were examined. The lengths and relative breadths of the tibia and fibula were compared across habitual locomotor types, with a focus on hominoids. Different locomotor types were characterized by hominoid, such as brachiation by lesser apes, knuckle or fist quadrupedalism and arm-swinging, including torso-orthograde forelimb locomotor behaviors, by great apes, and bipedalism by humans. The lower leg bones of great apes showed relatively large diameters, in particular, large distal breadths, in comparison with the length. Humans also showed relatively large diameters in many measuring points after those of great apes, but had differently shaped distal ends. The lower leg bones were relatively robust in these species, where a larger proportion of body weight was more habitually supported by lower/hindlimbs. Among quadrupedal monkeys, including prosimians, more terrestrially adopted animals showed larger diameters in comparison with length than did more arboreal ones in many measurements. Apes and monkeys who adopted brachiation or arm-swinging in their locomotor repertoire in arboreal environments exhibited relatively large distal end and tibial malleolus breadths compared with quadrupedal monkeys. A large breadth of the ankle compared with depth and a large malleolar breadth would help the inversion and eversion movements. The human ankle was relatively small in breadth compared with ape ankles and was adapted mainly to parasagittal rolling. The shape of the lower leg bones is therefore related to the differences in locomotor type and substrate use in primate species.

Case Study on the Diffusion of Digital Dental Technology Innovation
Authors: Fu Ta Yu
Published: February 2022

This research employs a case study of a professional dental medical equipment company in Taiwan, cites the theoretical basis of innovation diffusion, and uses the design-thinking double-diamond model to review the company's history of promoting digital IOSs in the market from ground zero. Integrating the theoretical foundations of medical institution procurement and innovation diffusion, this study finds that different target customers have very different perceptions and acceptance of new technologies. The knowledge and attitude of medical personnel are the primary factor affecting new technology procurement, only then will decision-making factors such as financial, functional, and service aspects be further considered.
Efficacy of Using Retro Games in Multimodal Biofeedback Systems for Mental Relaxation
Authors: Chand Kulbhushan , Khosla Arun
Published: February 2022

Video games are used to increase the engagement of biofeedback systems. For cost-effectiveness, the original Nintendo Entertainment System (NES) games can be used. Therefore, a multimodal biofeedback system was developed to leverage the NES games for biofeedback. This study aims to test the efficacy of the developed system, the motivation of participants, and the usability of the system. A within-group design study was conducted with 16 participants followed through four interventions: deep breathing, stress-test, non-biofeedback game (control), and biofeedback game (experiment), where their HRV was recorded. Participants showed significantly different HRV during interventions (F(1.60, 23.93) = 11.94, p < 0.001) and reported higher HRV when using biofeedback game than the non-biofeedback game (t(15) = 9.14, p < 0.0001). The motivation was reported to be the same with biofeedback and non-biofeedback version of the game, and the overall system was reported as usable. The results of this study support the efficacy of using original NES games in biofeedback for mental relaxation.

Published: February 2022

Think-alouds are a common method of collecting design data where a player describes their play for a facilitator. Games promote a feeling of immersivity and player presence, which is in tension with traditional think-aloud methods. This work introduces a new type of think-aloud protocol intended for game-based contexts that leverages the genres of video blogging and livestreaming in game culture. This new approach, called Play Aloud testing, has participants take on the role of a game streamer by expressing their thoughts, feelings, and experiences as they play – modeled after live streaming commentary. This paper demonstrates the potential of the Play Aloud approach using playtest data from a game called HEX of the Turtle Islands. The authors highlight how Play Aloud testing generated useful data providing insight into the experience of young players in a way that was authentic to the format of digital games and consistent with youth gaming practices.
An Efficient Accountable Oblivious Transfer With Access Control Scheme in the Public Cloud
Authors: Liu Xin , Zhang Bin
Published: February 2022

In an oblivious transfer with access control (AC-OT) scheme, the database provider (DBP) can define different access control policies for each data record, and users are allowed to hide their choices from the DBP when accessing data. An accountable AC-OT (AAC-OT) scheme is an enhanced version of AC-OT that allows the DBP to revoke the access rights of malicious users. However, existing AAC-OT schemes have defects in their security model definition, malicious user revocation mechanism, and user-side performance. Therefore, the authors proposed an improved AAC-OT scheme that applies to the public cloud environment. In the definition of the security model, the definitions of access authorization and revocation are considered. By modifying the user tracing mechanism, the DBP can independently revoke the access rights of fraudulent users. In addition, the number of bilinear pairing operations performed by users in the transfer phase is kept constant by optimizing the generation of the underlying zero-knowledge proofs.

Authors: Jiang Jiahong
Published: February 2022

Since the introduction of flipped learning, it has drawn much attention and enjoyed increasing popularity. This study attempts to investigate Chinese English majors' metacognitive strategy use in a flipped environment and the influencing factors of metacognitive strategy use. Thirty-five subjects were asked to study the assigned online course video lectures out of class and participate in activities demanding the application of acquired knowledge. Students' metacognitive strategy use and factors influencing their use were analyzed based on the data collected from written reflections, interviews, and classroom observations. Findings indicate that 1) planning, self-monitoring, self-evaluation, directed attention, and selective attention are students' main employed metacognitive strategies in and out of the flipped classroom; 2) factors influencing students' metacognitive strategy use consist of students' desired learning outcomes and group learning; and 3) students' self-control over learning pace in the flipped context further motivates their use of diverse metacognitive strategies.
Universal Sparse Adversarial Attack on Video Recognition Models
Authors: Li Haoxuan , Wang Zheng
Published: February 2022

Recent studies have discovered that deep neural networks (DNNs) are vulnerable to adversarial examples. So far, most of the adversarial researches have focused on image models. Whilst several attacks have been proposed for video models, their crafted perturbation are mainly per-instance and totally polluted ways. Thus, universal sparse video attacks are still unexplored. In this article, the authors propose a new method to explore universal sparse adversarial perturbation for video recognition system and study the robustness of a 3D-ResNet-based video action recognition model. A large number of experiments on UCF101 and HMDB51 show that this attack method can reduce the success rate of recognition model to 5% or less while only changing 1% of pixels in the video. On this basis, by changing the selection method of sparse pixels and the pollution mode in the algorithm, the patch attack algorithm with temporal sparsity and the one-pixel attack algorithm are proposed.

The 3D end-to-end video system (i.e., 3D acquisition, processing, streaming, error concealment, virtual/augmented reality handling, content retrieval, rendering, and displaying) still needs improvements. This paper scrutinizes the motion compensation/motion estimation (MCME) impact in the 3D video (3DV) from the end-to-end users' point of view deeply. The concepts of motion vectors (MVs) and disparities are very close, and they help to ameliorate all the stages of the end-to-end 3DV system. The high-efficiency video coding (HEVC) video codec standard is taken into consideration to evaluate the emergent trend towards computational treatment throughout the cloud whenever possible. The tight bond between movement and depth affects 3D information recovery from these cues and optimizes the performance of algorithms and standards from several parts of the 3D system. Still, 3DV lacks support for engaging interactive 3DV services. Better bit allocation strategies also ameliorate all 3D pipeline stages while being attentive to cloud-based deployments for 3D streaming.
An Image Quality Adjustment Framework for Object Detection on Embedded Cameras
Authors: Kong Lingchao , Ikusan Ademola , Dai Rui , Ros Dara
Published: February 2022

Automatic analysis tools are ubiquitously applied on wireless embedded cameras to extract high-level information from raw data. The quality of images may be degraded by factors such as noise and blur introduced during the sensing process, which could affect the performance of automatic analysis. Object detection is the first and the most fundamental step for the automatic analysis of visual information. This paper introduces a quality adjustment framework to provide satisfactory object detection performance on wireless embedded cameras. Key components of the framework include a blind regression model for predicting the performance of object detection and two distortion type classifiers for determining the presence of noise and blur in an image. Experimental results show that the proposed framework achieves accurate estimations of image distortion types, and it can be easily applied on embedded cameras with low computational complexity to improve the quality of captured images.

Published: February 2022

Lack of standard learning infrastructures in secondary and tertiary institutions in most developing countries have made learning cumbersome for the disabled, as most available learning environments were designed to cater mainly for normal learners with little or no consideration for learners with disabilities, thereby resulting to poor academic performance among these affected groups. This paper implements an ANFIS (adaptive neuro-fuzzy inference system)-based ubiquitous learning middleware to support disabled learners by providing suitable learning content for them. The system evaluation showed the effectiveness of the developed ANFIS-based u-learning system in proffering solutions to some of the challenges faced by disabled learners as the system attained 94% correctness, 88% satisfaction, 78% validation, 78% system simplicity, 88% system feedback, and 94% efficiency for the learners.
Citation Analysis of Potential Predatory Journals Removed From the UGC-CARE List
Authors: Jan Rosy
Published: February 2022

Keeping into consideration importance of citation analysis as a method of journal evaluation criteria study is initiated to highlight impact of journals which were removed by UGC presuming that journals are receiving citation attention as they are published by reputed publishers. The study aims to raise the awareness of increasing prevalence of citations to the journal articles considered as low quality by UGC. It demonstrated that many articles from the removed journals are deeply interwoven in the scientific literature and are cited by authors which later on publish in reputed publication outlet. Thus, the decision considering journal as low quality is not sufficient rather a proper mechanism should framed regarding citing low quality literature. Furthermore, declaring a journal as low quality or removing it from a country listing of white journals cannot change the entire landscape of scientific communication unless a collective effort at international level is initiated to curb the problem of low quality research and duplicated efforts.

Published: February 2022

Because of the capacity to work at any climate circumstance and infiltration ability through the clouds and soil, SAR (Synthetic Aperture Radar) imagery has been very demanding.SAR imagery system captures images from any satellite or moving object such as aircraft etc. As per the height of a RADAR system increases the resolution of SAR images is also increased. Due to high-resolution images and multiplicative noise known as speckle, it is not easy to analyze these images. So, it has become very important to remove speckle from these images.There are great numbers of de-speckling techniques have been proposed in past. It is very difficult to identify a suitable technique for a de-speckling task. In this article, authors have proposed a literature survey of some techniques.Authors compared best techniques based on their merits and the different parameters used so far for the observation of SAR images. In recent years, the popularity of deep learning has grown tremendously. For de-speckling of SAR images, various improved CNNs and deep learning based approaches have been proposed.
