La Medusa decapitata: la donna nel racconto ecfrastico La ripetizione di Andrea Camilleri e nel quadro La Vucciria di Renato Guttuso
Authors:   Uniwersytet im. Adama Mickiewicza w Poznaniu, Polonia, Bartkowiak Joanna
Published: February 2021

The main focus of this article is to find an image of the woman, provided by an ekphrastic work by Andrea Camilleri, La ripetizione, corresponding to a famous painting by Renato Guttuso, La Vucciria. The duality of the perception of the woman, in the rich and multi-millennial Sicilian culture, is reflected in the writer’s narrative through a clash of roles and an inversion of the positions commonly assigned to individuals by society. The analysis highlights the mutual exchange of glazes, defined by Laura Mulvey as “male” and “female,” and the installation within the framework of the observer reflected by the mirror, as proposed by Michel Foucault. The reflections of psychoanalysts, in particular Julia Kristeva and Melanie Klein, provide some explanations regarding the coexistence of the cult of the mother with the desire for matricide. According to these theories, the figure of the male child remains forever burdened by an inconsolable sense of guilt and frustration. Consequently, the male protagonists of Camilleri are tormented by a terror of and a disdain for the female body. In fact, their domination proves to be only illusory: the image of the woman is overwhelming and threatening like that of Trinacria, the mistress of Sicily. Finally, the male, fighting for his own identity, commits matricide and the Medusa is beheaded.
Invito alla riscoperta e alla traduzione di Mario Rapisardi
Authors:   Uniwersytet Wrocławski, Polonia, La Rosa Gabriele
Published: February 2021

This article is intended to constitute a first approach towards a critical, comparative, and bibliographic study of the forgotten figure of Catania-born Mario Rapisardi (1844-1912), “the Etnean poet.” A poet and polemicist, he expressed himself in the climate of Positivism during and after Italian Unification, distinguishing himself with an ethical temper that did not make him abandon the Promethean tension towards ideals. Due to these ideals, the poet came into conflict with both the academic and ecclesiastical worlds, resulting in his consequent literary isolation—but not social and human isolation, clearly demonstrated by the fact that more than 100,000 people would attend his funeral. This article is also an invitation to rediscover and translate Rapisardi’s work into Polish, as his presence is almost non-existent, given that only four short poems are translated into Polish: three published in 1921 (Disinganno, La montagna fatale, Dinanzi a un ritratto) and one in 1931 (Nox). The translations are by Jadwiga Lipińska, Józef Puzyna, Julian Ejsmond, and Julia Dickstein-Wieleżyńska, respectively. The article chronologically traces the Polish criticism of Rapisardi, starting from 1880 with two articles by Polish writers and literary critics Waleria Marrené-Morzkowska and Julian Adolf Święcicki, up to the present times, and is based both on studies by famous literary scholars, such as Maurycy Mann, and on articles that appeared in literary magazines, such as Przegląd Humanistyczny and Przegląd Współczesny.

Authors: Heredia Oscar , Chunga Xiomara , De La Cruz Lewis , Zimic Mirko
Published: February 2021

En respuesta al actual déficit a escala mundial de ventiladores mecánicos causado por el COVID-19, se ha desarrollado un prototipo de ventilador mecánico de bajo costo (aproximadamente 2500 USD) y alta precisión (error menor a 5%). Este equipo permite realizar ventilación mandatoria continua (CMV) controlada por volumen (V-CMV), por presión (P-CMV) y ventilación con presión soporte (PSV). Bajo la CMV se puede trabajar con disparo asistido y controlado; lo que, en combinación, suma un total de cinco modos de ventilación. Su construcción se basa en el uso de componentes comerciales de gama industrial, piezas mecanizadas con alta precisión y elementos de circuitos de ventilación clínica estándar.El mecanismo del prototipo consta de un cilindro dentro del cual se desplaza un émbolo accionado por un motor paso a paso. Esto se logra a través de un sistema de transmisión compuesto por un tornillo sin fin y una tuerca. Dependiendo de la cantidad y frecuencia de los pulsos eléctricos emitidos por el sistema de control, se define el avance y velocidad del émbolo. De este modo, el émbolo desplaza la mezcla de aire y oxígeno hacia el paciente.El prototipo fue evaluado en modo V-CMV mediante pruebas de laboratorio con un pulmón electrónico, que simula las condiciones de operación típicas. Como resultado se obtuvo un error promedio del 3% de las variables de funcionamiento del equipo.

Evaluation of a Food Supplement with Collagen Hydrolysate and Micronutrients on Skin Appearance and Beauty Effects: A Randomized, Double-Blind, PlaceboControlled Clinical Study with Healthy Subjects
Authors: Y Modinger , C Schon , K Vogel , M Brandt , S Bielfeldt , KP Wilhelm
Published: February 2021

Objective: Skin health, skin appearance and skin beauty are influenced by collagen composition of the dermis. Natural aging affects the structural integrity of the collagen network, resulting in drier skin, wrinkle formation and reduced skin elasticity. Orally ingested hydrolyzed collagen reaches the skin tissue and exerts beneficial effects on human skin from within. However, not only collagen peptides, but also micronutrients can beneficially affect skin appearance. Thus, dietary supplements for cosmetic and beauty effects containing combinations of collagen peptides and selected micronutrients are in demand. Aim of this study was to investigate the effect of a food supplement with collagen hydrolysate and micronutrients on skin beauty. The test product was assessed for its capability to reduce wrinkles and to improve skin hydration and collagen structure.

Knowledge for teaching, knowledge about teaching: exploring the links between education research, scholarship of teaching and learning (SOTL) and scholarly teaching
Authors: Case Jennifer
Published: February 2021

The relationship between education research and the scholarship of teaching and learning (SOTL) is still debated, while a distinction has been made between scholarly teaching and SOTL. This study compares and contrasts two programmes of work that took place in a particular 2nd year engineering course, both led by the author. The first programme was an educational research project investigating student learning in the course. The second programme was a period of teaching, leading to some SOTL output. Analysis of the knowledge drawn on in teaching, confirms that good university teaching is not a direct application of research findings but rather draws on a broad and largely tacit practical base of knowledge. The article also offers a deliberation on whether it is productive to maintain the distinction between education research and SOTL.
Teacher salary differentials using Purchasing Power Parity (PPP): a South African perspective as both a ‘source’ and ‘destination’ country
Authors: George Gavin , Rhodes Bruce
Published: February 2021

Teacher migration is a problem for developing countries as it impacts on delivery of quality education. The potential to earn higher incomes remains the most common factor driving teacher migration. This study seeks to investigate how the South African teacher salary structure compares with the equivalent salary structure in six prominent migrating countries whilst highlighting the economic appeal of South Africa from a Zimbabwean teacher perspective. Using a representative basket of commonly bought goods (including food, entertainment, fuel and utilities), a purchasing power parity (PPP) ratio is used to equalise the international price of buying that basket. Our study makes comparisons, using a PPP index, and allows the identification of real differences in salaries for our selected countries (South Africa, United States, United Kingdom, Canada, Australia, New Zealand, Japan and Zimbabwe) for selected teaching categories. Even when controlling for differences in the cost of living, the incentive for a South African teacher to seek work overseas remains strong and increases with career experience. A worrying conclusion for South Africa concerned with keeping its experienced teachers is that as more human capital is gained by experience, the greater the incentive to emigrate.
Die ‘moeilike reis’: Die skryf van ’n lewensverhaal oor ’n kontroversiële broer
Authors: Jordaan Annette
Published: February 2021

The essay reflects on the “difficult journey” undertaken when the essay writer was tasked to write the life story of her adoptive brother, the late lieutenant-general Lothar Neethling (1935–2005). His life story is a remarkable one: the author’s parents adopted this German war orphan in 1948 in his early teens; he became an exceptionally well qualified scientist and at the age of 35 he became the head of the South African Police Force’s forensic laboratory. The laboratory was instrumental in solving many crime-related cases during the period of National Party rule. Towards the end of 1989 newspaper reports implicated Neethling personally as the source of poison used against African National Congress activists. Although he ultimately won his case of defamation on appeal against these newspapers he was not exonerated unconditionally. The biographer reflects on her approach in writing his biography, the difficulties of balancing kindred loyalty, personal and collegial affinities and her objective to portray the life of a complex human being.

Desafíos en la formación de psicólogos de las organizaciones y el trabajo
Authors:   Universidad EAFIT
Published: February 2021

Desafíos en la formación de psicólogos de las organizaciones y el trabajo es un libro que mueve al lector hacia la radicalización de la reflexividad, como diría Anthony Giddens, y hacia la posibilidad de enfrentar el mundo por medio de la construcción de nuevas formas de pensar y actuar, saliendo de una POT enraizada en el siglo XX, para entrar en una POT dirigida hacia el siglo XXI, sin la pretensión ni la ingenuidad de pensar que ahora todo es diferente. ¿Podríamos, tal vez, hablar de una continuidad con rupturas y fisuras? Nuevas demandas del mundo del trabajo, la rivalidad paradigmática generadora de deformación de la identidad de carrera en POT, la investigación, la producción y las prácticas como estrategias de formación; la cuestión de la inclusión social, la formación como productora de subjetividades, los antagonismos y las interfaces con el coaching, el papel del sindicato, la emergencia de la psicología positiva, entre otras cuestiones, constituyen algunos temas abordados en este libro.

Published: February 2021

In acute stroke, emboli are mostly composed of thrombi from artery, cardiac chamber, valve and vein. Non-thrombotic emboli are sometimes difficult to identify the origin. According to the increased number of cancer patients, now 10% of stroke patients have a cancer. However, the potential mechanisms of stroke in patients with cancer are various. We presented a case of serious acute arterial occlusion with a tumor embolus, which was revealed by histopathologic analysis of retrieved emboli during mechanical thrombectomy.

Exploring student achievement and perceptions in an online flipped grammar course
Authors: Ahmad Djuwairiah , Arifin Muhammad Ahkam
Published: February 2021

Flipped learning to date has generally been implemented within a blended classroom. However, the growing number of fully online courses and the existence of Covid-19 have shown the need to try using flipped learning in a fully online class. This paper aimed to explore student achievement and perception in an online flipped grammar class. A paired-sample t-test showed a significant difference between student pre-test and post-test scores with a medium effect size after attending the online flipped course for one month. The interview and questionnaire data revealed students’ overall positive perception toward the introduction of flipped learning within the course. Students mentioned that the flipped approach made the course more interactive and provided them opportunities to ask questions to the teacher with an immediate answer. They also expressed their positive attitude towards the use of different learning platforms (e.g., LMS, Zoom) and modes (synchronous and asynchronous) that could ease their learning experience within the course. Nevertheless, students recommended that the virtual meeting via Zoom needs to be limited in time duration.
Metacognitive and critical thinking practices in developing EFL students’ argumentative writing skills
Authors: Murtadho Fathiaty
Published: February 2021

This action research examined the roles of writing instruction involving metacognitive and critical thinking strategy on the improvement of argumentative writing skills of college students in Indonesia. Argumentative writing is one of the pivotal topics among researchers investigating ways to improve college-level writing. This study involved 88 students of three parallel classes enrolled in the writing skill development course. Employing Kemmis and McTaggart’s (1988, 2014) model of action research, this study employed a three-cycle action study in one semester, covering four stages of learning tasks: understanding of the problem, monitoring of students’ learning activities, problem-solving, assessment, and conclusion drawing. Each cycle provided learning exercises of metacognitive and critical thinking to hone the students’ argumentative writing skills. Referring to critical skill criteria as a baseline, the analysis found that employing metacognitive and critical thinking processes in the instructional treatments enabled the students to improve their argumentative writing skills. The finding indicates a pivotal role of incorporating metacognition in writing instruction as a strategy to improve college-level writing skills.
Redefining language and literature learning in the transformation era

Published: February 2021

The study was aimed at redefining the learning of language and literature from the perspective of media use in the lesson planning and implementation and students’ responses towards language and literature learning. The subjects of the study were teachers and students of state junior high schools in a regency in Yogyakarta Province. The subjects were taken in three stages, first, with the cluster technique: the eastern, western, central, and northern zones, and second, with the school strata technique: as excellent, moderate, and low. The choice of strata technique was determined based on the results of the 2017 National Exam score ranking. Third, the selection of schools and classes was made randomly. Primary data were obtained from observation, interview, and document analysis; secondary data were obtained from a questionnaire. Results can be described as follows. First, media use designed in the lesson plan included conventional, new, and audio-visual media. Second, media use in the carrying out of the lesson was realized by the teachers in the forms of conventional visual and audio-visual media. Third, students gave fair responses to the use of instructional media in language and literature learning. In the low-coded schools, the use of media designed in the lesson plans was more varied than that of the moderate- and excellent-coded schools; the most preferred new visual media were PowerPoint. In moderate- and low-coded schools, instructional media were shown to have positive impacts on student activity in learning; namely, students were more active because learning was more fun. Contradictorily, instructional media did not have positive impacts in excellent-coded schools on student activity in learning; namely, students were less active because learning was considered unpleasant. As seen from the perspective of the transformational era, no teacher had used interactive digital media.
Online support-provision in the self-disclosure of eating disorders
Authors: Zulkarnain Nur Azwin , Jan Jariah Mohd , Wahid Ridwan
Published: February 2021

This paper highlights the importance of appropriate communication with individuals who suffer from eating disorders (ED). The negative perception that society has towards ED often leads its patients to conceal their problems and avoid seeking help (Perveen et al., 2017). Understanding the manners in which support-providers approach ED patients in order to eliminate the fear is therefore important. Data was collected from the National Eating Disorders Association (NEDA) website from January to March 2018, where support-providers’ responses to posts of self-disclosure were qualitatively analyzed through computer-mediated discourse analysis (CMDA) using McCormack’s (2010) Categories of Social Support and Blum-Kulka and Olshtain’s (1984) Cross-Cultural Study of Speech Act Realization Patterns (CCSARP). Drawing on the categories of social support proposed by McCormack, it was found that most of the strategies that the support-providers opted for were highly positive and indirect in nature. The findings also showed that the indirect support given was often complemented with words of encouragement and a number of suggestions that were offered as part of the support itself. This allowed the support-providers to appear unimposing on the ED patients while being able to ensure that they were guided on the possible means of recovery.
Emerging voice: Exploring the process of teacher-students’ dialogic interaction in mobile instant messaging (MIM) to construct voice in argumentative writing
Authors: Latipah Yeni , Gunawan Wawan
Published: February 2021

Despite the growing body of literature on the role of Mobile Instant Messaging (MIM) in supporting educational practice, little comprehensive understanding could be gained on how to scrutinize dialogue between teacher and students in MIM for the sake of students’ meaning-making. Thus, this study explored the process of teacher-students dialogic interaction in a MIM group as a viable pedagogical activity in fostering students’ establishment of voice in argumentative writing. Particularly, it focused on the construction of Engagement resources (Martin White, 2005) as the realization of voice in the students’ writing. To reach the objectives, a qualitative case study with multiple data sources were employed, i.e., the records of instant messaging conversation, students’ argumentative text, interview, and observation. The findings revealed that the teacher-students’ discussions in the instant messaging space were enjoyable activities that could support the students’ awareness of Engagement resources because they allowed the discovery of repertoires through reasoning, problem-solving, and peer learning. Furthermore, although there were various uptakes of Engagement resources in the students’ text, most students showed progressive achievements in applying the sources effectively in their writing.

Authors: KESİLMEZ Emrullah Cem , YÜKSEL Zafer
Published: February 2021

Amaç: Bu çalışmada Kahramanmaraş ili sınırları içerisinde doğan bebeklerde nöral tüp defekti (NTD) sıklığının belirlenmesi, NTD’li bebeğe sahip ailelerin sosyo-demografik özelliklerinin, annelerin gebelikleri süresince özellikle ilk trimestrda teratojen etkenlere maruz kalıp kalmadığının araştırılmasıdır. Gereç ve Yöntemler: Ocak 2000-Aralık 2013 tarihleri arasında Kahramanmaraş ili sınırları içerisindeki canlı ve ölü doğum kayıtları retrospektif olarak değerlendirilmiş ve Kahramanmaraş Sütçü İmam Üniversitesi Tıp Fakültesi Hastanesi Nöroşirurji kliniği dahil Kahramanmaraş ilinde Nöroşirurji kliniği barındıran tüm hastanelerde NTD tanısı alan hastalar incelenmiştir. Sosyodemografik özellikler, gebeliğin ilk trimestrında karşılaşılan teratojen etkenler, anne ve babaların meslekleri, aylık maddi gelirleri ve akrabalık durumları, annelerin ateşli hastalık geçirme öyküsü, ilaç ve alkol kullanımları anket yöntemiyle değerlendirildi. Bulgular: Çalışmamızda 907 NTD’li hasta değerlendirildi. Hastaların 702’sinde (%77.4), spina bifida, 528’inde (%58.2) meningomyelosel,134’ünde (%14.8) meningosel, 40’ında (%4.4) dermal sinüs traktı, 107’sinde (%11.8) anensefali, 98’inde (%10.8) ensefalosel tanısı mevcuttu. Kahramanmaraş ilinde NTD sıklığı ‰3.83 olarak bulundu. Hastalardan 574’ü (%63.2) kadın, 333’ü (%36.8) erkek cinsiyetteydi. Olguların ebeveyn meslekleri değerlendirildiğinde işsizler veya ayda birkaç gün işçi olarak çalışanlar anlamlı oranda yüksekti. Ailenin gelir seviyesi ve annelerin eğitim seviyesi düşüktü. NTD’li bebeğe sahip annelerin gebelikleri sırasında folik asit preperatı kullanım oranının ise çok düşük olduğu görüldü (%11.4). Sonuç: Çalışmamızda Kahramanmaraş ilinde NTD görülme sıklığı ülkemizdeki benzer çalışmalar içinde göreceli olarak yüksek bulunmuştur. NDT’li bebeklerin ailelerinin düşük sosyoekonomik düzeyde olması ve annelerin yetersiz eğitim seviyeleri sonucu gebelik öncesi dönemde veya gebelik esnasında folik asit kullanımının ilimizde ciddi olarak düşük olması bu yüksek NTD sıklığının sebebi olabilir. Ayrıca NTD hastalarında doğumda veya sonradan ortaya çıkabilecek ek patolojiler olabileceği ve bu hastaların multidisipliner yaklaşımla, deneyimli kliniklerce takip ve tedavisinin yapılması gerektiği sonucuna ulaşılmıştır.
UHMWPE IN TOTAL KNEE ARTHROPLASTY: SUCCESSES AND FAILURES
Authors: Camacho Nayeli , Gonzalez Juan Manuel , Espinosa Diego , Mondragón Guillermo , Stafford Stephen
Published: February 2021

El polietileno de ultra alto peso molecular (UHMWPE por sus siglas en inglés) ha sido el estándar de oro para los reemplazos de rodilla durante más de cinco décadas. Este biomaterial, utilizado ampliamente en el sector ortopédico, ha sido constantemente modificado para disminuir su tasa de desgaste en las prótesis de rodilla. Hoy en día, los reemplazos totales de rodilla tienen una tasa de supervivencia del 95 % después de 10 años, 88.7 % después de 15, y 82 % después de 25 años. Sin embargo, la vida útil del componente de UHMWPE a menudo se limita entre los 15 a 20 años, ya que el daño por desgaste de las superficies del UHMWPE es inevitable. En pacientes más jóvenes y más activos, el desgaste puede acelerarse, generando una cantidad considerable de partículas y provocando una falla prematura. Se han reportado reacciones adversas en el tejido circundante de la articulación de la rodilla debido a la presencia de estas partículas, especialmente en el rango de 0.3 to 2 μm, que a menudo conducen a un aflojamiento aséptico inducido por osteólisis. Las investigaciones se han centrado en mejorar la resistencia al desgaste y el rendimiento del UHMWPE. En este trabajo, se analiza el comportamiento de desgaste y el rendimiento clínico del UHMWPE desde el punto de vista de la ciencia de los materiales, así como las modificaciones existentes para mejorar la resistencia al desgaste de este polímero; la reticulación mediante irradiación gamma, la estabilización de vitamina E y la incorporación de diferentes nanopartículas.

Potential copper plant Vanyukov furnace gas desulphurization capacity
Authors: Platonov O. I. , Tsemekhman L. Sh.
Published: February 2021

To enable maximum disposal of Vanyukov furnace flue gas, the authors of this paper examined the spare capacity of the Elemental Sulphur Site at the Copper Plant of Nornickel’s Polar Division. Thus, the paper considers an optimized three-stage flue gas treatment process (which also includes a thermal reduction stage) and the possibility to skip the stage of preliminary condensation of sulphur from reduced gas. To estimate how it will affect the overall recovery of sulphur (desulphurization factor), a series of calculations was carried out to compare the Elemental Sulphur Site’s performance during two different treatment processes: a complete process that includes preliminary condensation of sulphur from thermally reduced gas; and a short process, i.e. without preliminary condensation of sulphur. In both cases, the concentration of sulphur dioxide in the Vanyukov furnace gas was [SO2] = 28 vol %. The results of the calculations were verified through experiments conducted on a pilot unit owned by Gipronikel Institute with the gas flow reaching ~1.2 nm3/h, and they confirm the possibility of implementing the three-stage treatment process using the available plant space and reaching the capacity of 40,000 nm3/h and the sulphur recovery of ~89 %. The obtained data on the specific consumption rates of natural gas, oxygen and boiler water can be used for a feasibility study to justify the adoption of the short treatment process at the Elemental Sulphur Site of the Copper Plant of Nornickel’s Polar Division.

Quite a few studies have been carried out that look at the application of microwave energy for material processing in various spheres. Microwaves can selectively and quickly heat the target bulk material thanks to its dielectric properties. Gold ores have a complex mineral composition and the effect of microwaves is different on different minerals. This enables to heat selected areas of the rock causing a strong thermal stress. This leads to microcracks occurring at the mineral boundaries resulting in weaker grains and hence better grinding performance. Refractory gold concentrates contain a lot of sulphides, which get hot instantly when exposed to microwave radiation. Thus, microwave energy can be efficiently used to roast sulphide gold concentrates. During microwave roasting, heat conversion takes place directly in the sulphides and the reaction starts immediately. That’s why microwave roasting is a much faster process compared with convection roasting. This paper provides a brief overview of microwave energy used for gold ore and concentrate processing and describes the behaviour of minerals in the microwave field, as well as the results of a number of studies that looked at using microwave energy to destroy rocks, roast refractory sulphide gold concentrates and regenerate charcoals. The key advantages of microwave radiation include an easy process control, the possibility to quickly and selectively heat the product and low energy costs.

This paper considers the key control issues related to non-adjustable parameters in the production of metallurgical silicon in ore thermal furnaces. A series of experiments has been conducted to confirm the possibility of introducing the electrode off-position control. Thus, additional control parameters were introduced in the process control system. The electrode positioning algorithm was tested and adjusted to minimize electrode bending and reduce the risk of breakage and to minimize end cracking and spalling during restarting in the current production environment. An integrated 3D model of the thermal field distribution has been developed and built that accounts for the charcoal moisture content, the position of the electrodes and the power emitted as the charge gets hot. Substantiation is given to the application of this adaptive adjustment algorithm to control the changing parameters as determined by the process conditions, such as the moisture content of the charge, the position of the electrode, the power mode of the furnace. The authors propose to expand the existing control system by adding a digital module, i.e. due to the integration of electrode off-position signals and the use of the adaptive adjustment algorithm and avoiding using any additional corrective signals. This research was carried out as part of the Governmental Assignment No. 075-03-2020-127/1 for the year of 2020, Project No. FSRW-2020-0014. Subject: A crossdisciplinary approach to the comprehensive exploitation of natural resources and conservation. Area (a 2020 topic): “Comprehensive processing of minerals and man-made materials and gasification of solid hydrocarbons: A review and concept elaboration”. As greenhouse gases and carbon are produced as a result of electrode destruction, it is proposed to use the method of gasification and dispose of the heat produced.
LLEGAL GROUNDS FOR REGULATION FOR CERTAIN FORMS OF ARRANGEMENT FOR CHILDREN IN INTERNATIONAL FAMILY LAW
Authors: Radchenko L.
Published: February 2021

The article considers legal principles of regulation for relations of guardianship, care and adoption in international family law, the regulation of these forms of arranging children in law and their interpretation in the legal doctrine of certain foreign states, the definition of features and peculiarities of these concepts, the definition of relations in this field, as well as formulation of conclusions and proposals aimed at harmonization of national legislation with the law of leading foreign states.

Legal grounds for the regulation of the relations of guardianship, care and adoption in the legislation of some foreign countries shows that there are different legislative approaches to the regulation of such forms of placement of children. Historical, religious, national factors, elements of tradition and culture – all these factors significantly affect the substantive content of the essential traits of care, and adoption in different countries.

At the same time, the basic provisions of such institutions are unchanged – both guardianship and adoption are intended to promote the upbringing and development of the child, to guarantee the exercise of their rights and legitimate interests, to ensure their care and custody.

Custody relations are regulated both on the basis of conflict law rules and in accordance with substantive rules of private international law. For example, in Ukraine the establishment and cancellation of custody of minors, disable persons are regulated by the personal law of the ward. The obligation of the guardian to accept guardianship is determined by the personal law of the person appointed by the guardian. The relationship between the guardian and the person under guardianship is determined by the law of the state the body of which appointed the guardian.

The regulation of relations for international adoption is subject to conflict of law rules. In Ukraine, adoption and its abolition are governed by the child's personal law and by the adopter's personal law. A person's ability to be an adopter is determined in accordance with his or her personal law. The legal consequences of adoption or termination are determined by the personal law of the adopter.
One of the areas of state activity regarding adoption should be effective monitoring and control over the processes of adoption including the participation of foreign entities as well as the further upbringing, care and observance of the rights and interests of children who have been adopted by foreigners.

Authors: Ugrunovska O. , Piniashko M.
Published: February 2021

The article examines the functioning of the judicial procedure for establishing the facts of birth and death on the temporarily occupied territory of Ukraine in terms of its regulation and effectiveness. The authors analyze the procedural nature of the separate proceeding according to national legislation of Ukraine in comparison with legal framework of several foreign states. As a result, it has been stated that the establishment of the above-mentioned legal facts is not the only Ukrainian know-how. Specific attention has been paid to the issues of juridical technique regarding the determination of participants that can submit an application in order to set a fact of birth or death of a person. In particular, it has been found that Ukrainian legislator does not circumscribe such categories as "persons who can hand in an application" and "applicants". It has been delineated that lodging an application by the applicant's attorney does not substitute the presence of the independent legal interest, which is necessary to become applicant. In addition, the article explores the process of proving. It has been concluded that the burden of proof rests on the applicant. However, the court is obliged to be an active participant of the proving in order to establish the circumstances of the case, namely: to request evidence, order to carry out expertise etc. The subject-matter of the cases concerning the establishment of facts of birth or death of a person on the temporarily occupied territory of Ukraine comprises, inter alia, the circumstances regarding time and place of birth (death), familial relationships between the applicant and the person who was born (died). Finally, the article examines the enforcement of the "Namibian exception" in the context of the evaluation of the evidence.

Published: February 2021

La revolución digital ha transformado los modos de hacer, actuar y formar en el ámbito universitario. Por ello, el fomento y desarrollo la competencia digital docente (CDD) en Educación Superior es un aspecto clave en el siglo XXI. El propósito de este estudio es conocer el nivel de competencia digital del profesorado universitario andaluz, así como identificar si existen diferencias significativas entre la autopercepción antes y después de realizar el cuestionario. Para ello, se plantea un diseño no experimental con enfoque descriptivo y contraste de hipótesis. La muestra objeto de estudio queda conformada por un total de 2262 docentes pertenecientes a las 9 universidades públicas de Andalucía (España), que contestan el instrumento DigCompEdu Check-In adaptado al contexto español. En términos generales, los resultados muestran que el nivel es moderado. En concreto, las áreas mejor valoradas han sido las de Pedagogía Digital y Recursos Digitales. Así mismo, se demuestra que la autopercepción antes de realizar el cuestionario es superior a la realizada en un momento posterior. Estos datos explican el fenómeno denominado como idealización competencial. Por este motivo, se recomienda llevar a cabo planes personalizados de formación docente avalados por marcos sólidos como DigCompEdu.
