Microbial synthesis of nano-selenium and nano-titanium dioxide: mechanisms of selenite respiration
Authors: Nouri Sabere , Yousef-Saber Fatemeh , Emtiazi Giti , Habibi Neda
Published: January 2023

The unique physicochemical properties of nano-metals compared with those of non-nanomaterials have led to many investigations in recent decades. Nano-titanium dioxide has been chiefly applied in novel implant forms. Also, the structures of selenium-containing compounds play a critical role in the biological activity of these elements. According to recent studies, nano-selenium is not only less toxic, but also has a higher biological activity than selenium ions such as selenium (IV) (Se4+) and selenium (VI) (Se6+). Researchers have turned to green nanostructure synthesis due to the drawbacks of chemical techniques. This paper presents a literature review on recent advances in microbial synthesis methods for producing nano-selenium and nano-titanium dioxide. Despite numerous research articles on green nanoparticle production, little information has been provided on the microbial formation of titanium and selenium nanoparticles. This review paper focuses on the possible mechanism of nano-selenium production by selenium respiration. Although there are reports of microbial synthesis of these particles, their production by probiotic bacteria is of great value. Considering the compatibility of probiotic bacteria with the immune system and their tremendous applications in medicine, it is suggested to use them in combination with nano-titanium dioxide and nano-selenium for various ends such as implant scaffolds and food additives, respectively.
Multi-hazard performance evaluation of hillside buildings under earthquakes and landslides
Authors: Kulariya Mahipal , Saha Sandip Kumar
Published: January 2023

Earthquake-induced landslide, a cascading hazard in hilly regions, can substantially increase the damaging effects of an earthquake. This necessitates performance evaluation of buildings situated in hilly regions under the effects of landslide-only and landslides following earthquakes. In this study, the performance of two commonly observed hillside building configurations is assessed—namely, step-back and split foundation—subjected to the above-mentioned multi-hazard scenarios using an uncoupled approach. The uncertainty in the soil properties that influence the landslide-induced forces is considered based on laboratory tests of soil samples collected from active landslide sites and an existing database of landslide events. Three-dimensional hillside buildings are analysed for uphill-side landslide scenarios by performing force-controlled non-linear static analyses. Further, a suite of earthquake ground motions is scaled to a predefined intensity level, and then non-linear time history analyses are performed to obtain the damaged state of the buildings prior to assessing the landslide response. It is observed that the earthquake loading history and its direction of excitation significantly affect the response of hillside buildings to a landslide following an earthquake. Further, the step-back building is observed to be more vulnerable to landslide damage when compared to its split foundation counterpart for a given uphill-side landslide scenario.

Dependencia y adicción al smartphone entre el alumnado universitario: ¿Mito o realidad?
Authors: Roig-Vila Rosabel , López-Padrón Alexander , Urrea-Solano Mayra
Published: January 2023

El avance y desarrollo de las tecnologías digitales ha provocado que el smartphone sea ya parte integrante de la existencia humana. Esto resulta particularmente evidente entre las generaciones más jóvenes, quienes lo utilizan frecuentemente en casi todas las facetas de su vida. No obstante, el consumo desproporcionado y desequilibrado de este tipo de dispositivos puede llegar a generar un grave impacto en su bienestar físico y mental. Esto, unido a las elevadas tasas de empleo de este colectivo, provoca que en ocasiones su uso sea catalogado como dependiente y adictivo. Sin embargo, la adicción al teléfono móvil sigue siendo debatida entre la comunidad científica. Por ello, este estudio se propuso identificar el perfil de utilización del alumnado universitario respecto al smartphone y determinar si este es problemático. En la investigación participaron 350 estudiantes del 1er curso de los Grados de Magisterio en Educación Infantil y Primaria de la Universidad de Alicante (España). Todos ellos cumplimentaron un cuestionario sobre esta temática. Los datos se procesaron con el programa de análisis estadístico SPSS versión 25, con el que se realizó un estudio descriptivo. Los resultados indican que, si bien en ocasiones el smartphone se convierte en un medio para evitar la soledad, la mayoría de participantes presentaba un patrón de consumidor habitual, vinculado a otros usuarios o redes. Por tanto, desde la perspectiva del alumnado universitario, el uso de este tipo de dispositivos no puede ser calificado de dependiente o adictivo. Por ello, y a la vista de sus potencialidades para el aprendizaje, se concluye subrayando la necesidad de integrarlo en las aulas universitarias, pero previendo los riesgos que su uso excesivo puede ocasionar.

Published: January 2023

Anemia is a common complication of chronic kidney disease (CKD), and its prevalence rises as the disease progresses. Intravenous or subcutaneous erythropoiesis-stimulating agents (ESAs) are advised to treat CKD-associated anemia, since shortage of erythropoietin (EPO) and iron are the main cause of anemia. However, ESA resistance and safety have spurred a lot of interest in the development of alternate anemia therapies. Roxadustat, an orally administered hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) that increases erythropoiesis and may modulate iron metabolism, was recently licensed in China, Chile, South Korea, Japan and the European Union for the treatment of CKD-related anemia. Despite this, clinical trials have shown a number of adverse effects, including cardiovascular disease, hyperkalemia, and infections. In addition, of concern is roxadustat's possible effects on other organs and systems. In this review, based on clinical evidence, we discuss the potentially detrimental effects of roxadustat to the known biology on systems other than kidney, and the need for long-term follow-up in order for roxadustat to be approved in more countries in the future.

This work presents a historical perspective on the studies of photoluminescence in mercury cadmium telluride (HgCdTe), one of the most important materials of infrared photoelectronics. The first part of the review considers the results of the studies performed during the early years of the development of the technology of this material (1966-1996). These studies were carried out mostly using samples of bulk crystals and epitaxial films grown by liquid-phase epitaxy. The results of the studies allowed for identification of the nature of optical transitions in HgCdTe, including excitonic emission, interband recombination, donor-acceptor pair recombination and recombination via shallow and deep levels, which greatly helped in maturing the material technology.

Published: January 2023

Müzik, profesyonel ya da rekreatif olarak egzersiz yapan bireyler tarafından sıkça kullanılmaktadır. Buna karşın, farklı egzersiz türlerinde müziğin performansa etkisine ilişkin çalışmaların sayısı sınırlıdır. Bu araştırmanın amacı, izokinetik dinamometrede 50 tekrarlı diz ekstansiyon ve fleksiyon hareketlerini içeren bir kuvvette devamlılık testinde, Öz-Seçim Müziğin (ÖSM) kuvvetle ilgili performans bileşenleri ve Algılanan Zorluk Derecesi (AZD) üzerine etkisini incelemektir. Araştırmaya 34 erkek katılımcı (Yaş x̄= 21.26±1.71 yıl, Boy x̄= 179.41±5.79 cm, Vücut Ağırlığı x̄= 77.70±9.03 kg) gönüllü olarak katılmıştır. Katılımcılar, dengelenmiş çapraz araştırma desenine göre müzikli ve müziksiz olarak farklı zamanlarda iki kez testi tamamlamıştır. Katılımcıların AZD’leri testten hemen sonra Borg Skalası ile ölçülmüştür. Araştırmada kuvvetle ilgili performans bileşenleri olarak; Kuvvette Devamlılık (KD), Zirve Tork (ZT) ve Toplam İş (Tİ) değişkenleri incelenmiştir. Verilerin analizi için Bağımlı Gruplarda t-Testi ve testin parametrik olmayan karşılığı Wilcoxon Z-testi kullanılmıştır. Bulgular, dizde ekstansiyon hareketinde, KD [t(33)= 1.102; p= 0.27], ZT [t(33)= 1.02; p= 0.31] ve Tİ [t(33)= 0.956; p= 0.34] ölçümleri açısından, müzikli ve müziksiz koşullar arasında anlamlı bir fark bulunmadığını ortaya koymuştur. Dizde fleksiyon hareketi için ise, benzer şekilde KD (Z= -0.692; p= 0.48) ve Tİ (Z= -1.872; p= 0.06) değişkenleri için anlamlı fark görülmezken, ZT değerlerinde müzikli koşulda anlamlı fark (Z= -2.266; p= 0.02) olduğu görülmüştür. Son olarak, AZD değerleri açısından iki koşul arasında anlamlı fark bulunmamıştır [t(33)= -0.549; p= 0.58]. Sonuç olarak, ÖSM kullanımının yüksek şiddetli bir egzersiz sırasında kassal performans parametreleri ve AZD üzerinde pozitif bir etkisi görülmemiştir. Ancak, fleksiyonda ZT’deki anlamlı artış, bu hareketten sorumlu hamstring kas grubunda, müziğin daha yüksek şiddette çalışma kapasitesi yarattığını ortaya koymuştur. Egzersiz sırasında ÖSM kullanımı, belirli kas gruplarının performansı üzerinde olumlu bir etki yaratabilir.

Published: January 2023

To reconcile the personalization-privacy paradox, we adopt the privacy as a state view and define privacy as a state of information boundary rule-following. We further identify five types of boundaries underlying some of the important implicit rules of maintaining privacy: communication channel, platform, device, temporal, and purpose boundaries. Using an online vignette survey, we investigated how each of these boundary types affected users’ privacy perceptions when they were subjected to personalized advertisements. Using fixed- and random-effects models, we investigated how violating different boundary rules leads to changes in perceived privacy. Our results show that all five boundary types are significant predictors of perceived privacy within individuals. The communication channel, device, and business versus private purpose are significant predictors of perceived privacy across the whole sample. Temporal boundaries and platform boundaries failed to achieve statistical significance when evaluated simultaneously with the other factors across the whole sample. This means that for each individual, observing the rules of these five boundary types leads to higher perceived privacy than not observing these conditions. Taken as a whole, observing communication channel, device, and business versus private purpose boundaries also leads to higher averages of perceived privacy across the whole sample. Theoretical and practical implications are discussed based on the results
Guidelines for the Development of Three-Level Models: Bridging Levels of Analysis and Integrating Contextual Influences in IS Research

Published: January 2023

The use of multilevel analysis has steadily increased in information systems (IS) research. Many studies are doing an admirable job of integrating two-level models into their examination of IS phenomena. However, two-level models are limited in how well they enable researchers to (1) more explicitly incorporate context into theory development and testing and (2) bridge the existing gap between micro- and macrolevel research by focusing on intervening mechanisms that link hierarchically distal levels of analysis. Three-level models have emerged as a potential way to address these limitations. While the literature has clearly outlined the mechanics of how to estimate three-level models, there is very little, if any, guidance on when and how to integrate the use of such models with theory development. Consequently, IS researchers have little guidance to inform their decisions about integrating the use of three-level models with their theory development and testing. In this article, we identify the circumstances under which IS researchers should consider the use of three-level models, develop guidelines about how to map the use of three-level model estimation to the theoretical objectives, and provide an illustration of how to implement the guidelines.
AT SCHOOL OR HOME? EIGHT GRADERS’ FIRST PRACTICES WITH ONLINE GEOMETRY LESSONS
Authors: SAHIN DOGRUER Sule
Published: January 2023

Undoubtedly, one of the areas most affected by the Covid-19 pandemic process was educational activities. In this study, the eighth graders of a public elementary school in Turkey were observed for a six-week online learning period. The aim was to obtain whether any changes occur in their geometry attitudes during process and to reveal their preferences between online distance learning (ODL) and regular face-to-face education. In this context, structured as a mixed study, a Geometry Attitude Scale (GAS) and a questionnaire about online distance learning was administered at the beginning; further GAS and learners’ opinions in response to open-ended questions were administered at the end of the process. Quantitative results indicated that gender and mathematics achievement levels have no relationship with GAS and ODL. Still, the qualitative analysis provided that ODL does not cause any change in students' attitudes towards geometry lessons; moreover, students commonly prefer face-to-face education over ODL.

This work seeks to understand the determinants of student dropout in the courses offered by Open University of Brazil system at the Federal University of Santa Maria. To achieve this objective was used: survival function, factorial analysis and logistic function. The mean dropout rates at the UAB/UFSM were close to 47%, and for undergraduate courses this rate was 50.5%, higher than that of postgraduate, from 43.4%. The probability of a student dropping out of a course is 58.85%, and is higher among male students, with higher income, who resides at a greater distance and who need to move more frequently to perform activities in the classroom. Also, it was found that the perception of the academic aspects as adequate and the greater time of dedication reduce the probability of dropout.
INSTITUTIONAL ADOPTION AND IMPLEMENTATION OF BLENDED LEARNING: DIFFERENCES IN STUDENT PERCEPTIONS
Authors: ALI Ramiz
Published: January 2023

Blended learning (BL) has been a popular mode of course delivery in higher education, aiming to provide students with better learning experiences by integrating face-to-face (f2f) instructions and affordances of digital technology. However, lack of knowledge about how students perceive BL cross-disciplines can make it difficult for teachers to provide consistent learning experiences to students, yielding inequity in learning experiences. This study aims to explore how university students perceive BL, and to compare differences in perceptions across subjects. Participants were 407 university students from eight subject disciplines. Data were collected through a questionnaire and were analysed using SPSS. A one-way ANOVA was performed to compare the differences between the groups. Results showed, students were generally happy about use of BL, despite facing multiple barriers in using the learning approach. Results further revealed, students studying tourism/hospitality, and business subjects were more negative about BL, while students in science and engineering, and Islamic studies faculties were more receptive to BL compared to the rest of the university. Implications for adoption and implantation of BL, and teacher support are discussed.

The work is related to the study of surface waves in solving seismic acoustic location problems during the movement of moving objects, and in assessing the accuracy of determining the coordinates of moving objects of different origins. In solving the inverse problems of seismic acoustic location, the surfaces of the wave that occur on the Earth's surface during the movement of a moving object are studied. The accuracy of the solution of the inverse problem directly depends on the errors: determination of the time of entry of the seismic acoustic wave, the velocity characteristics of the environment, noise of various origins, the choice of the geometry of the location of sensors. The need to study surface waves, namely Rayleigh Waves and Lion Waves, is justified because they propagate on the Earth's surface. The plane of oscillation of Rayleigh waves is vertical to the Earth's surface and direction of propagation, and Lev waves have a horizontal plane of oscillation. As one of the considered problems of seismic acoustic location as a source of energy of a moving object, we take seismic energy, which occurs during human walking. Human walking is periodic. It excites impulses of displacement in the geological environment. According to the known coefficient of rigidity of the medium, it is possible to determine what will be the maximum deviation of the seismic receiver. The paper investigates surface waves, Rayleigh and Lev in solving seismic acoustic location problems during human movement, and identifies factors that affect the accuracy of determining the coordinates of a moving object. In terms of using surface waves to solve seismic location problems to identify moving objects, they have the following advantages: the energy of these waves does not disappear deep into the Earth, but propagates below its surface; their formation takes more than 60% of the energy of the source, and the formation of deep waves only 8%, such waves have much more energy; From this it can be concluded that even at low energies of the excitation source surface waves can be used to solve seismic location problems during the movement of moving objects and to assess the accuracy of determining the coordinates of these objects.

The urgency of the issue of quantitative assessment of technical perfection of aircraft weapons is determined primarily by the task of comparing alternative models and choosing the best options when developing or purchasing for the needs of the Armed Forces of Ukraine. Analysis of the practical application of known methods of decision theory shows that they do not actually solve the problem of estimating the technical level of the product in quantitative terms, but only allow to build a certain priority series of evaluated products in order of increasing / decreasing their technical level. ) the magnitude (degree) of change in the level of technical excellence of one product in relation to another. In this sense, qualimetric methods allow for quantitative assessment of the technical level (quality) of products in relation to the basic (reference) sample, which determines the convenience of their use to solve problems of choice. But the use of the methodological apparatus of qualimetry in each case requires its adaptation taking into account the characteristics of the evaluated product in terms of substantiation of its defining indicators of technical excellence and determining their relative importance. The article presents the results of the authors' research on the development of methods for assessing the technical level (quality) of guided aircraft as part of the support system for decisions on the development / purchase of samples of weapons and military equipment for the Armed Forces of Ukraine. The developed methodology is based on a qualimetric complex method of quality assessment of complex technical systems, based on the ratio of determinants of technical excellence of the evaluated and basic (reference) products, taking into account the relative importance (weight) of such indicators. The presented technique allows you to quickly (with minimal time compared to expert evaluation procedures) to calculate the technical level of aircraft damage in order to compare (select).

The article analyzes the institutional transformation of the sphere of social services in the context of the development of the non-profit sector. The institutional transformation in the field covers the issues of changing public attitudes, the level of public trust and prevailing stereotypes. Besides, online interactions that are spreading while providing and receiving services influence the processes of the individual choice under constantly changing market conditions. The results are based on two sociological surveys devoted to studying the attitude of citizens towards the non-profit sector of social services. The surveys were conducted in Russian regions in 2019(n=1204) and 2020 (n=2047). Among the factors influencing public attitudes towards NGOs are citizens' understanding of the meaning of social services, awareness of non-state service providers and the opportunities of NGO social service sector. During the COVID-19 pandemic, people tended to resort to online services more often, we assume that this hastened the transition to the online format of interaction in the analyzed field. The revealed relationship of attitudes towards state and non-state type providers has demonstrated that the attitude of citizens towards one type of social service provider has an impact on the formation of attitudes towards another type of provider confirming that public trust is systemic. We have identified the key stereotypes that determine the choice of the type of provider by the recipients of services. It has also been found that the personal experience of interaction with social services organizations plays an important role for establishing trust in state and non-state social services organizations. The dynamics of the public trust in the non-profit sector of social services has been analyzed based on the identification of age subgroups.
The New Education: Controversies and Solutions
Authors:   Vologda Research Center of the Russian Academy of Sciences, Golovchin Maksim A.
Published: January 2023

The article examines the consequences of the evolution of the national education system as a result and source of ideology, which is formed by two parallel paradigms of the development of modern society and the state – traditional and liberal. In Russian education, these paradigms are constantly changing: from state-bureaucratic socialism in the USSR (1917–1990) and liberal reforms in post-Soviet Russia (1990–2000) to educational counter-reforms of the first twenty years of the 21st century. In modern education, a number of solutions still appear, in which a certain ideological structure is laid. An example of this is the expert report of the Center for Strategic Research and the National Research University Higher School of Economics "Twelve Solutions for a New Education", the main messages of which boil down to reforming the national educational system according to the liberal model. We pay special attention to the controversy of the ideas of the report on the support of "elite" schools instead of solving the current issues of the development of the educational network and infrastructure; on the concentration of methods for solving the problems of teachers in terms of creating conditions for improving their qualifications (ignoring the financial difficulties characteristic of this professional group). Author comes to the conclusion that ideology is important for solving the problems of the education system and its agents, from the standpoint of which the national educational policy is formed. From our point of view, responses to modern challenges to education should provide for the interests and opinions of the scientific and educational community within the framework of “institutional bricolage” (the creation of institutions “from below”, at the expense of the resources of the educational community).
The image of a synthetic in the Alien franchise: the phenomenology of human-robot interaction
Authors: Stolbova Natalia V.
Published: January 2023

In the article the representation of a synthetics image in the Alien franchise is analyzed. The analysis was carried out in the context of human-robot interaction. The methodological basis of the research is the tool-analysis developed by M. Heidegger (fundamental ontology) and rebuilt by G. Harman and T. Morton (object-oriented ontology). During the analysis of the Alien franchise, the dynamics of scientific and technological progress in the field of robotics presented in the films and the main ways of programming the anthropomorphic robots of the saga are shown. As a result, several main images of synthetics were revealed: a robot-subject, as close as possible to a human being in its abilities; a robot is an obedient machine that follows the orders of its creator and corporation; a robot who can be the part of society, because it can "read" the social context; a robot is more human than a human. As a result, in films, robotics as an industry is in decline, and synthetics having really become better and more human than people refuse to obey: they burn their modems and dissolve in society, become indistinguishable from people. The article concludes that as a result of the development of the plot the emphasis in the saga shifts from robotics to cyborgization. And despite the fact that the films retain a humanistic setting (the cyborg Ripley 8 is the exception, not the rule) the dynamics of the rapprochement between Aliens and humans and their machinerization demonstrate the fragility of the border between humans and non-humans. A transition to post-humanistic practices of coexistence of people and non-humans is being built. In the "Alien 4" which shows the practices of communication between people, synthetics, (a hybrid of Ripley and Aliens) a transition is being built to post-humanistic practices of coexistence between people and non-humans.

The article theme is topical for the reason that Ilya Ilf in Zapisnye knizhki criticizes the socialist realism the art that propagandized and did not pay attention to the artistic expression quality and originality. In recent decades we can witness return of social realistic writing in the works of such authors as A. Ivanov, Z. Prilepin, K. Silvanova and E. Malisova. It appears that in the course of studying the classic Stalinist social realism and critical reflecting it is possible to understand certain patterns of the modern literature process. The research objective was to study Ilf's critique peculiarities and its objects. The article basic research methods comprise semiotic and intertextual analyses. The article beginning considers the context of Ilf's writing in 1930-s years. The stories by Ilf and Petrov, E. Zozulja and Barricady [Barricades] novel by P. Pavlenko were considered as the empiric material. As a result of the research, two thematic dominants of the writing were distinguished: 1) critical judgment of I. Ilfs literature colleagues who started working in social realistic manner in 1930-s years; 2) ironic attacks at the forming social realistic canon. Both of the writing thematic domains are polar opposite to Ilf and Petrov's artistic expression within the specified period. The coauthors created several social realistic texts, and some parts of Odnoetazhnaya America [One-storied America] are semantically compliant with the key Soviet ideology intentions. Thus, it is possible and necessary to distinguish between Ilfs independent creative working and the coauthors late works, where E. Petrov was an evident leader.

Background and Aims: Recurrent pregnancy loss (RPL) is one of the important complications of pregnancy. Only 50% of cases have a known cause of RPL. One of the causes of RPL is Waddlia Chondrophila (W. Chondrophila), but no information is available regarding its in Iran. This study aimed to develop a Taqman Real-Time polymerase chain reaction assay to detect recA Gene of W. Chondrophilain biological samples from women with RPL in Yazd city.
Materials and Methods: Clinical samples of women with a history of RPL, normal childbirth, and standard strain WSU 86–1044 were provided. Primers and probes of W. Chondrophila were designed. Positive control was provided based on the PUC57 vector. Technical performance was examined using a control plasmid.
Results: Analytical sensitivity was 5 ng/µl of control plasmid DNA. No cross-amplification was observed when testing other pathogens that can detect in human vaginitis. The Taqman Real-Time PCR assay exhibited good reproducibility. This Real-Time PCR was then applied to 100 vaginal swabs. No samples were revealed to be Waddlia positive.
Conclusions: This new TaqMan Real-Time PCR assay represents a diagnostic tool that may be used to further study the prevalence of W. Chondrophila infection in clinical specimens.

Background: Families are willing to spend their entire lives improving their children due to emotional attachments, which, in turn, increases their exposure to catastrophic health expenditures (CHEs). The present study aimed to estimate the level of exposure to CHEs and its determinants among households with pediatric cancer and oncology disorders.
Materials and Methods: This cross-sectional study was performed on 101 households with pediatric cancer and oncology patients who referred to Shahid Sadoughi Hospital of Yazd in 2021. The CHE in this regard was defined as the out-of-pocket payments for hypertensive care that equaled or exceeded 40% of the household capacity to pay. The data on each household were collected with reference to the patient's electronic file and through a questionnaire completed during an interview with the head of the household. The data were also analyzed with descriptive statistics and logistic regression in Excel (2019) and STATA ver.15.
Results: Out of 101 households in the study, 43 (42.6%) incurred CHEs (based on a threshold of 40% of disposable income). Regarding the job of the heads of households, manual workers were vulnerable to CHEs up to 11.7 times more than employees and self-employed individuals (OR=11.7, p<0.05). Also, the lower the education level of the head of the household, the higher the risk of facing CHEs (OR=10.45, p<0.05). Similarly, the lower his or her income, the higher the CHE.
Conclusion: The results showed that households with pediatric cancer and oncology disorders were significantly exposed to CHEs. Due to the limited resources of the health system in the treatment of cancer patients and the need for expenditure control programs, it seems better to focus on cost control strategies for this group of patients.

Few data are available about hydatid cysts in patients with malignancy; however, these have rarely been described in association with leukemia. The purpose of this report was to present an unusual case of coexisting leukemia and pulmonary hydatid cysts.This study presented a 13-year-old boy with acute myeloid leukemia who was diagnosed with bilateral pulmonary hydatid cysts after the completion of chemotherapy and successfully treated with surgery and albendazole. Managing hydatid cysts in patients with leukemia is difficult, and these individuals are also at risk of developing ruptured and infected cysts during chemotherapy. Based on our experience with this case, an oncologist could postpone surgery until the chemotherapy was completed and begin albendazole if hydatid cysts were detected.
