Abstract- The implementation of the COVID-19 emergency curriculum has a learning policy, namely a policy from home. Policies from home (online) create new challenges for all aspects and in every circle. Teachers, students, and parents must adjust to the current situation and situation. Several problems arise due to the implementation of the policy, including the ability of teachers to use technology, inadequate facilities, and lack of enthusiasm from students. To prove this problem, research is needed to analyze the problem. This study uses quantitative research by collecting data using questionnaires, from filling out the questionnaire it is hoped that it can become a forum for the aspirations of students, teachers, lecturers, and the community to express opinions regarding the implementation of the COVID-19 emergency curriculum. The results show that there is a significant impact on the learning process at home. They said that studying at home was less concentrated than studying at school. In addition, the readiness of teachers to teach online is lacking, especially for senior teachers who cannot apply technology in learning. So that learning at home cannot be carried out optimally.
Abstrak- Penerapan kurikulum darurat covid-19 mempunyai kebijakan belajar, yaitu kebijakan dari rumah. Kebijakan dari rumah (daring) membuat tantangan baru bagi seluruh aspek dan di setiap kalangan. Guru, peserta didik, dan orang tua harus menyesuaikan keadaan dan situasi pada saat ini. Beberapa persoalan timbul karena penerapan kebijakan tersebut, diantaranya kemampuan guru dalam menggunakan teknologi, fasilitas yang tidak memadai, dan semangat yang kurang dari peserta didik. Untuk membuktikan persoalan itu diperlukannya penelitian untuk menganalisis permasalahan tersebut. Penelitian ini menggunakan penelitian kuantitatif dengan pengumpulan data menggunakan kuesioner, dari pengisian kuesioner tersebut diharapkan dapat menjadi suatu wadah aspirasi peserta didik, guru, dosen, dan masyarakat untuk menyampaikan pendapat mengenai penerapan kurikulum darurat covid. Hasil menunjukkan terdapat dampak yang signifikan terhadap proses pembelajaran di rumah. Mereka menyebutkan konsentrasi belajar di rumah kurang dibandingkan belajar di sekolah. Selain itu, kesiapan guru dalam mengajar secara online kurang, khususnya bagi guru senior yang tidak bisa dalam pengaplikasian teknologi di dalam pembelajaran. Sehingga pembelajaran di rumah tidak bisa dilaksanakan secara optimal.

The Role of Intellectual Property Rights in the Technological Age
Authors: Vindele Liene , Cane Renate 
Published: June 2022

Abstract
The last two decades have seen a huge technological development, also known as the technology explosion, making it easier for anyone to access any kind of information, including of course intellectual property, anywhere in the world, and this has created new challenges for the protection of intellectual property. But nowadays, technology not only allows access to any work of authorship or invention, it is also capable of creating works of authorship or inventions itself, leading legal scholars to debate whether works created by technology can be protected if they are not human‐made. As is well known, almost all national laws only recognise an author or inventor if it is a human‐made work, but what about a painting or invention created by artificial intelligence? Are such works becoming vulnerable and freely available to everyone today? The methodological basis of this article is based on general scientific approaches (analysis and synthesis, deduction and induction, comparison, analogy and a systemic and structural‐functional approach). The article also draws on court decisions, legislation, legal literature, publications and doctrine. Conclusions are drawn using the method of scientific induction and deduction. The aim of this article is to explain the importance of intellectual property protection in today's technological age, where intellectual property can be created not only by people but also by technology.
Procedural Mechanism for the Implementation of Public Interest in the Context of Consumer Rights Protection
Authors: Jucevičius Ramūnas 
Published: June 2022

Abstract
The practice of the last few years shows a significant increase in the number of consumer applications to public authorities for protection of their violated rights. As the main guarantor of consumer protection in the field of public administration, the State Consumer Rights Protection Authority bears a heavy administrative burden as a result. Consumer surveys show that they are indifferent to their rights, both in terms of their content and their protection. On the other hand, rules of civil procedure designed to ensure the right of access to a court are not an appropriate guarantor of public interest for consumers due to their complexity. As a consequence of all these circumstances, the current legal mechanism for consumer rights protection does not ensure a prompt and efficient process.

Authors: Lošaks Gvido 
Published: June 2022

Abstract
The Latvian Group of Companies Law focuses on creditor and minority shareholder protection and is less concerned with pursuing the interest of the group. This research paper will look at the regulation of group of companies in Latvia. It will question whether the interest of the group is effectively recognised in the Latvian Group of Companies Law. The methodology used will be that of legal doctrinal and comparative research, legal theory method and reform agenda research. The research paper will conclude that creditor protection under Article 27, paragraph 5 of Group of Companies Law (Koncernu likums) is ineffective.
El turismo termal y la fabricación de esferas navideñas en Chignahuapan, Puebla como mecanismo de la descampesinización local
Authors: Quintero Venegas Gino Jafet 
Published: June 2022

La nueva ruralidad, la descampesinización y la tercerización económica, constituyen tres nociones que evidencian una dura transformación económica, social y espacial en las concepciones tradicionales del mundo rural. A partir de la inserción en el sistema mundial bajo, la etiqueta de “Pueblo Mágico”, Chignahuapan, una comunidad rural mexicana del centro del país, ha dejado de lado las actividades del sector primario para impulsar al terciario y ha adoptado al turismo como eje rector del crecimiento económico. El objetivo de este trabajo es visibilizar cómo la transformación económica local, hacia el turismo, se ha dado a partir de mercantilizar un manantial de aguas termales con propiedades curativas, y a partir de la fabricación de esferas navideñas de vidrio soplado, una actividad económica que ha posicionado a la localidad en el imaginario nacional. Así, en Chignahuapan se ha generado una relación de dependencia hacia el turismo, asociada con las necesidades y demandas de las dos grandes ciudades del centro de México: la Ciudad de México y Puebla.

Abstract
Galactic supernova remnants (SNRs) and their environments provide the nearest laboratories to study SN feedback. We performed molecular observations toward SNR W49B, the most luminous Galactic SNR in the X-ray band, aiming to explore signs of multiple feedback channels of SNRs on nearby molecular clouds (MCs). We found very broad HCO+ lines with widths of dv ∼ 48–75 km s−1 in the SNR southwest, providing strong evidence that W49B is perturbing MCs at a systemic velocity of V

LSR
= 61–65 km s−1, and placing the W49B at a distance of 7.9 ± 0.6 kpc. We observed unusually high-intensity ratios of HCO+
J=1–0/CO J=1–0 not only at shocked regions (1.1 ± 0.4 and 0.70 ± 0.16) but also in quiescent clouds over 1 pc away from the SNR’s eastern boundary (≥0.2). By comparing with the magnetohydrodynamics shock models, we interpret that the high ratio in the broad-line regions can result from a cosmic-ray (CR) induced chemistry in shocked MCs, where the CR ionization rate is enhanced to around 10–102 times of the Galactic level. The high HCO+/CO ratio outside the SNR is probably caused by the radiation precursor, while the luminous X-ray emission of W49B can explain a few properties in this region. The above results provide observational evidence that SNRs can strongly influence the molecular chemistry in and outside the shock boundary via their shocks, CRs, and radiation. We propose that the HCO+/CO ratio is a potentially useful tool to probe an SNR’s multichannel influence on MCs.
On the Stability of Low-mass Planets with Supercritical Hydrospheres

Published: June 2022

Abstract
Short-period, low-mass water-rich planets are subject to strong irradiation from their host star, resulting in hydrospheres in a supercritical state. In this context, we explore the role of irradiation on small terrestrial planets that are moderately wet in the low-mass regime (0.2–1 M
⊕). We investigate their bulk properties for water content in the 0.01–5% range by making use of an internal structure model that is coupled to an atmosphere model. This coupling allows us to take into account both the compression of the interior due to the weight of the hydrosphere and the possibility of atmospheric instability in the low-mass regime. We show that, even for low masses and low water content, these planets display inflated atmospheres. For extremely low planetary masses and high irradiation temperatures, we find that steam atmospheres become gravitationally unstable when the ratio η of their scale height to planetary radius exceeds a critical value of ∼0.1. This result is supported by observational data, as all currently detected exoplanets exhibit values of η smaller than 0.013. Depending on their water content, our results show that highly irradiated, low-mass planets up to 0.9 M
⊕ with significative hydrospheres are not in a stable form and should lose their volatile envelope.
High-energy Emission Component, Population, and Contribution to the Extragalactic Gamma-Ray Background of Gamma-Ray-emitting Radio Galaxies
Authors: Fukazawa Yasushi , Matake Hiroto , Kayanoki Taishu , Inoue Yoshiyuki , Finke Justin 
Published: June 2022

Abstract
In this study, we systematically studied the X-ray to GeV gamma-ray spectra of 61 Fermi Large Area Telescope detected radio galaxies. We found an anticorrelation between peak frequency and peak luminosity in the high-energy spectral component of radio galaxies, similar to blazars. With this sample, we also constructed a gamma-ray luminosity function (GLF) of gamma-ray-loud radio galaxies. We found that blazar-like GLF shapes can reproduce their redshift and luminosity distribution, but the log N–log S relation prefers models with more low-z radio galaxies. Utilizing our latest GLF, the contribution of radio galaxies to the extragalactic gamma-ray background is found to be 1%–10%. We further investigated the nature of gamma-ray-loud radio galaxies. Compared to radio or X-ray flux-limited radio galaxy samples, the gamma-ray-selected sample tends to lack high radio power galaxies like FR II radio galaxies. We also found that only ∼10% of radio galaxies are GeV gamma-ray loud. Radio galaxies may contribute to the cosmic MeV gamma-ray background comparable to blazars if gamma-ray-quiet radio galaxies have X-ray to gamma-ray spectra like Cen A, with a small gamma-ray-to-X-ray flux ratio.
Une ou deux périphrases à valeur progressive en français québécois de tous les jours ? ‹ Être après INF› et ‹ être en train de INF›
Authors: Dostie Gaétane 
Published: June 2022

Cet article traite des périphrases à valeur progressive ‹ être après INF› et ‹ être en train de INF›. La première était en usage dans les français d’Europe au temps de l’extension coloniale au xvii e siècle. Elle s’entend sporadiquement, encore aujourd’hui, en français québécois spontané, en parallèle à ‹ être en train de INF›. On s’intéresse ici aux valeurs exprimées par ces deux périphrases, à quelques décennies d’intervalle. La comparaison porte sur leur utilisation au début des années 1970 et à l’époque actuelle. Par-delà un renversement de leur fréquence d’usage durant cette période, les périphrases étudiées ont été et sont toujours conceptuellement équivalentes. On considère que la faible fréquence de la catégorie « progressivité » en français a facilité l’abandon graduel de ‹ être après INF› au profit de ‹ être en train de INF›, qui s’est peu à peu imposée comme forme normée.

Jouer collectif : autorités et identités dans Le Monde renversé du Collectif Marthe
Authors: Bahier-Porte Christelle , Schweitzer Zoé 
Published: June 2022

Le Collectif Marthe composé de quatre comédiennes, autrices et metteuses en scène (Clara Bonnet, Marie-Ange Gagnaux, Aurélia Luscher, Itto Medhaoui) s’est inspiré de la figure, historique et mythique, de la sorcière pour son premier spectacle Le Monde renversé (2018). Fruit d’une écriture collective, le texte et le spectacle interrogent et thématisent le phénomène même de pluralité, par le choix d’une écriture polyphonique qui met joyeusement en tension des paroles différentes : récits, discours, citations, fictions, documents d’archives ou ouvrages savants se répondent et « se complètent », selon une expression récurrente du texte. La figure de Marthe, nourrie de l’histoire des sorcières aussi bien que du quotidien des comédiennes, devient emblématique d’une identité féminine non normative qui porte avec elle des enjeux politiques modernes. L'écriture collective n'est pas seulement une solution dramatique adaptée à un travail collectif mais comporte un enjeu éthique qui s'avère particulièrement fécond pour penser une identité plurielle.
Au sujet du « pluriel » : Une « didactique de la Relation » à la lumière de Jean-Luc Nancy (Être singulier pluriel, 1996).
Authors: Claude SPRINGER , Frédérique LONGUET 
Published: June 2022

Suite à la publication de leur dernier ouvrage sur la « didactique de la Relation », les auteurs proposent un éclairage complémentaire à partir du livre de Jean-Luc Nancy, Être singulier pluriel. Le but de cet article est d’expliciter le terme « pluriel » qui caractérise la didactique du « pluri »linguisme en l’élargissant à la question ontologique de l’« être pluriel ». La didactique des langues-cultures est ainsi invitée à faire sa « révolution copernicienne » en s’inscrivant explicitement dans des approches sociales fondées sur la collaboration et les médiations réticulées.
Myopia prevalence in school-aged children in Garki District of Abuja, Nigeria
Authors: Akinbinu Tope R. , Naidoo Kovin S. , Wajuihian Samuel O. 
Published: June 2022

Background: Prevalence of myopia is increasing globally, hence it poses a significant public health risk due to the association of high myopia with debilitating eye disorders.Aim: The aim of this study was to determine the prevalence of myopia in school children.Setting: The study was conducted in primary and secondary schools in Garki district, Abuja, Nigeria.Methods: A cross-sectional, multistage, random sampling involving 1028 school children (aged 5–14 years), comprising 484 boys (47.1%) and 544 girls (52.9%), was conducted. Examination performed included visual acuities, pen torch and ophthalmoscopy examination of the anterior and posterior segments, retinoscopy under cycloplegia and subjective refraction.Results: The prevalence of myopia (−0.50 dioptre [D] or more) in this study was 3.5%. Approximately 3.4% of the children had mild myopia (−0.50 to −3.00 D), 0.1% had moderate myopia (−3.25 D to −6.00 D) and none had high myopia. Myopia ranged from −0.50 D to −4.25 D. The mean spherical equivalent for myopia (right eye) was −1.11 D. The prevalence of hyperopia, astigmatism and amblyopia was 5.8%, 1.9% and 0.7%, respectively. Overall, the prevalence of refractive error was 11.2%.Conclusion: The prevalence of myopia is relatively low in a sample of school children in Garki district of Abuja, Nigeria. However, the majority of myopic children in this study without spectacles (88.9%) are a cause for concern, which could reflect the low usage of refractive error services among school children in the district.
Sperm DNA fragmentation does not affect the clinical outcomes in the cumulative transfers of an ICSI cycle along with blastocyst transfers in couples with normozoospermic male patients
Authors: Repalle Deepthi , Saritha K. V. , Bhandari Shilpa 
Published: June 2022

Objective:
To know whether sperm DNA fragmentation (SDF) affects the clinical outcomes in the cumulative transfers of an intracytoplasmic sperm injection (ICSI) cycle along with blastocyst transfers in couples with normozoospermic males.

Methods:
The study included 252 couples who underwent their first ICSI cycles along with blastocyst transfer and whose male partner semen samples were normozoospermic according to the World Health Organization 2010 criteria. All the couples were classified into two groups based on the SDF: the low SDF group (SDF≤30%, n=162) and the high SDF group (SDF>30%, n=90). Clinical as well as laboratory outcomes were correlated between the two groups. Sperm DNA fragmentation was assessed on the post-wash semen samples by acridine orange test. The main outcome measures were the live birth rate and miscarriage rate.

Results:
A significant decrease in the live birth rates was observed in the high SDF group compared to the low SDF group in fresh embryo transfer cycles (P<0.05). However, no significant difference was observed in the clinical outcomes either in the frozen embryo transfer cycles or in the overall cumulative transfer cycles (P>0.05). No significant difference was observed in the laboratory outcomes between the two SDF groups. A remarkable decrease in sperm motility was observed in the high SDF group compared to the low SDF group (P<0.05).

Conclusions:
Sperm DNA fragmentation does not affect the clinical outcomes in the cumulative transfers of an ICSI cycle along with blastocyst transfers in couples with normozoospermic males.
Antioxidant potential of pentoxifylline on spermatozoa of small ruminants
Authors: Alomar Mazen 
Published: June 2022

Objective:
To investigate antioxidant potential of pentoxifylline on spermatozoa of small ruminants including rams and bucks.

Methods:
The levels of hydrogen peroxide (H2O2) production in ram and buck spermatozoa incubated with 0 (control), 4 and 8 mM of pentoxifylline were measured after 45-min incubation. Then, the motility parameters of ram and buck spermatozoa incubated with 0 (control), 1 mM of H2O2, 1 mM of H2O2 plus 4 mM of pentoxifylline, and 1 mM of H2O2 plus 8 mM of pentoxifylline were analysed. H2O2 was estimated using a fluorometric assay and spermatozoa motility characteristics were analyzed using computer aided sperm analyzer.

Results:
Pentoxifylline significantly decreased the levels of H2O2 produced from both ram and buck spermatozoa (P<0.05), and significant lower rates of H2O2 formation were noted when 8 mM of pentoxifylline was added (P<0.05). The values of all sperm motility parameters for the two species significantly decreased after incubation with H2O2 (P<0.05). In contrast, when the spermatozoa were incubated with both H2O2 and two concentrations of pentoxifylline, the motility values rose significantly compared to those incubated with H2O2 alone (P<0.05). For both ram and buck sperm samples, the rapid and static subpopulation motility parameters were the most affected categories by pentoxifylline addition compared to the medium and slow categories.

Conclusions:
Pentoxifylline possesses an antioxidant capacity proved by its ability of reducing H2O2 levels as well as by increasing motility values of stressed spermatozoa. Therefore, pentoxifylline could be recommended as antioxidant additive for spermatozoa of small ruminants under stress conditions.
