Metabolic “footprints” of the circulating cancer mucins: CA125 in the high-grade ovarian cancer
Authors: Chagovets VV , Vasil'ev VG , Iurova MV , Khabas GN , Pavlovich SV , Starodubtseva NL , Mayboroda OA
Published: December 2021

Mucins are large glycoproteins characterized by the abundant O-linked oligosaccharides (O-glycans) clustered on a protein backbone. Most of the circulating mucins are rapidly cleared by glycan-recognizing hepatic clearance receptors in the liver. Those mucins that remain in the bloodstream are most commonly used as markers in clinical diagnostics. One of such circulating mucins is MUC16; a peptide epitope of which is known as CA125 antigen — a marker for ovarian cancer. Here, using a targeted 1H-NMR profiling of plasma we are exploring a link between the measured CA125 values and the systemic metabolism of the patients within a group with confirmed high-grade ovarian cancer. The study allowed identifying statistically significant associations between the measured values of CA125 epitope and the plasma concentrations of glucose, glutamine, alanine, betaine and serine. The significance of the identified associations for the listed compounds is below 0.01. This, in turn, enables us to hypothesize about a possibility of including the metabolic measures into a composite score of the ovarian cancer based on the CA125 epitope of MUC16.

Omics technologies hold great potential as the basis for development of the new diagnostic approaches in obstetrics. Cervicovaginal fluid (CVF) as part of the mother-placenta-fetus system can be used to diagnose obstetric complications. This study aimed to identify the features of lipid composition of the cervical canal secretion peculiar to Intrauterine Growth Restriction (IUGR) and preeclampsia (PE). We took CVF samples from 57 pregnant women and subjected them to an in-depth clinical-anamnestic and mass-spectrometric analysis. Lipid extracts of CVF were analyzed with a liquid chromatography system coupled with a mass analyzer. As a result, we identified 239 lipid compounds. In case of 17 lipids, mathematical analysis revealed significant differences between samples from women with normal pregnancy indicator values (normal group) and patients from the IUGR group (p < 0.05). As for the normal group and PE group patients, there were significant differences identified for 3 lipids (p < 0.05). Comparison of samples from the PE and IUGR groups yielded statistically significant differences in levels of two lipids (p < 0.05). Mainly, the lipids were oxylipins, sphingomyelins, triglycerides, and cardiolipins. The developed diagnostic model had the sensitivity of 0.81 and specificity of 0.91 (cut-off level — 0.50; AUC — 0.85). The data obtained are valuable in the context of development of the new methods of diagnosing placentaassociated complications of pregnancy and for understanding new mechanisms of pathogenesis of these complications.

Fragmented Narratives: Exploring Storytelling approaches for Animation in Spatial Context
Authors:   Lusófona University, Vidakovic Lea
Published: December 2021

Animation is considered a prevalent medium in contemporary moving image culture, which increasingly appears across non-conventional surfaces and spaces. And while storytelling in animation films has been extensively theorized, narrative forms that employ physical space as part of storytelling have been less explored. This paper will examine the narrative aspect of animation works which are screened outside the traditional cinematic venues. It will look at how these animation works tell stories differently - using the full potential of the space, as a narrative device, a tool, and a stage where the narratives unfold. This paper will look at the historical perspective and the state of the art in animation installation today, exploring the relationship between the space and narrative in pre-cinematic, cinematic and post-cinematic conditions. It will examine how narrative structures in animation have changed over time, on their way from the black box of the cinema to the white cube of the gallery and even further, where they became part of any space or architecture. Through case studies of works by Tabaimo, Rose Bond, William Kentridge and other relevant artists, the interdependency of the narrative and the space where it appears will be explored, in order to identify new strategies for storytelling in animation. The aim of this paper is to emphasize the storytelling novelty that animation installations offer, which goes beyond the narrative structures that we are used to see on a single flat surface.
Concrete Abstract: Exploring Tactility in Abstract Animations from Early Avant-garde Films to Contemporary Artworks
Authors:   Namık Kemal University, Kaptan Siray Basak
Published: December 2021

After witnessing social chaos and the collapse of values at the beginning of the twentieth century, avant-garde artists insert new thought patterns and progressive aesthetic into the traditional perception of art. Being enthralled by the new film medium, former painters like Viking Eggeling, Walther Ruttman and Hans Richter start to experiment with light in two-dimensional film formats, they animate lines, stripes, basic shapes, play with the foreground and the background, and, most important of all, they construct a temporality within the visual order of the screen. Viking Eggeling’s Symphonie Diagonale (1921-24), Walther Ruttman’s Opus I (1921) and Hans Richter’s Rhythmus 21 (1921) show such temporality built in, which is caught by the idea of music as their titles suggest. These short abstract animation films attempt to discover the artistic possibilities of the new developing medium, film. Like the pioneer avant-garde abstract filmmakers, today’s artists still seek to stimulate a new perception for a possible embodiment that will activate the sense of touch in the audience. Tactility, enhanced by the material, opens up a new network of spatio-temporal relationships in the viewer's consciousness and subjecthood. This essay aims to bring a historical perspective to the abstract moving images of which the tactile or haptic experience is a defining characteristic. Through a selection of abstract animations, the materiality of the film image and the screening site will be elaborated upon according to the haptic features that are corporally embodied by the viewers. In the light of historical abstract animation, the aim is to dwell upon the dynamics of a continuous tendency to capture tactile instances to help bring forth the spatial resonances as well as visualize and reedify the rhythmic passing of time.
The Beauty of the Fragment Reconstituted in the Great Wall
Authors:   School of Communication and Creative Arts, De Bruyn Dirk
Published: December 2021

Max Hattler’s short abstract animations demonstrate an awareness of the form’s historic 1920’s European Abstract Animation precedents, is informed by the structurally focused minimalism of the 60’s and re-tools pre-cinema toys. Yet his work speaks to the contemporary technological environment he occupies and experiences directly. His move to Hong Kong and his recent Serial Parallels is also a predictive probe into future media environments. Hattler’s digital architectures are designed to make sense of the technological situation of speed and information overload which Vilem Flusser marks as amnesic and Marshall McLuhan identifies as an acoustic space readable through pattern recognition. His practice makes productive use of the flexible and modular qualities of contemporary digital image-making technologies for both production and publication purposes.
Visualizing Berio’s Sinfonia: Choreographing Animation for Indeterminate Narratives
Authors:   Institute Boundary Crossings, Bond Rose
Published: December 2021

In 1968, a year of massive political and cultural upheaval, Luciano Berio composed a score that would shape his legacy. Entitled Sinfonia, which literally means sounding together, the symphony was sparked by the assassination of Martin Luther King. Heralded as “the ultimate pre-postmodernist musical palimpsest” (Service, 2012). Sinfonia reverberates with the political assassinations and massive protests punctuated by police repression that marked 1968. In late 2019, I was offered an animated projection commission with a primary voice in choosing a piece for live symphonic performance/projection. After some researching, I found Berio’s Sinfonia. It had what I was looking for - a “contemporary” piece, it resisted illustration, linear narrative and 19th century romanticism while eschewing the rigid formality of serialism. Instead, it embraced two core Modernist principles – fragmentation and use of the archive. Berio quoted/sampled disparate chunks of literature, music, and events of 1968 in the service of the political and the poetic to discover unity in the heterogeneous. His score seemed ripe for visual interpretation - and exposition - with animation as the prime driver. Following Berio’s lead, I chose visual sampling as my entre and turned to Google. By animating in and out of iconic (and lesser known) images in the orb of 1968, I created a commensurate puzzle piece that mirrored the suggested avant-garde intent I found in Sinfonia – “Where now? Who now? When now?” (Beckett, 1965, p. 291).
Animated Urban Surfaces: Spatial Augmented Reality in public discourse
Authors:   FH Joanneum University of Applied/ FH Burgenland University of Applied Sciences, Tritthart Martina
Published: December 2021

Today´s projection art on public surfaces developed from the mutual approximation of painting, architecture, and lighting during centuries. The terms “Spatial Augmented Reality” (SAR) and “projection mapping” describe mostly temporary large screen projections on urban surfaces. The façade architecture becomes the screen for the content, mostly projected 2D and 3D animations. In essence, many of these artworks generate illusionistic clips deriving from the existing façade structure, allowing reality and fiction to merge audio visually. Artists, architects, curators, and institutions are increasingly aware of their responsibility related to this form of the mediatization of architecture, as shown, for example, by the Brazilian artist group Visualfarm. Their members approach their work as a counterpoint to the commercialization of public space in its appropriation by industry, propaganda, and advertising. But on the other hand, they also make a living from commercial assignments. Artists and architects often see themselves as pioneers and experimental researchers for possible developments in the coming digitized cities. By presenting various examples by selected artists like Corrie Francis Parks, Pablo Valbuena and Robert Seidel, the role of animation in connection with an alternative approach to the concepts of augmented realities within this process of social and urban evolution will be discussed. These artists try to integrate digital content into the cityscape in a harmonious sense.
Stage-directing the Virtual Reality Experience: Developing a Theoretical Framework for Immersive Literacy
Authors:   Ulster University, Melki Henry
Published: December 2021

Despite the incremental improvement and inclusion of immersive technologies in entertainment, training simulation, fine art, inclusive design, academia, and education; Virtual Reality (VR) still faces issues regarding its ability to compete with films and animation in visual storytelling without merging into the realm of video games. In 2015, Pixar’s Ed Catmull warned moviemakers that Virtual Reality is “not storytelling” and argued that the linear aspect of narratives poses an obstacle that cannot be overcome with VR. In contrast, Catmull argued that VR has immense application in games. However, VR creators have been pushing the boundaries and possibilities of delivering narratives in virtual spaces. In 2019, the VR experience “Gloomy Eyes” was presented at the Sundance festivals featuring a 30-minute story split between 3 episodes. The simulation is structured to provide its audience with some degrees of freedom while guiding them intuitively through the virtual space. In 2021, Blue Zoo also released a VR project titled “The Beast” featuring a cyclist powering up a snow-covered mountain. The short film was entirely created in Quill VR with the intention of being treated like a theatrical play rather than a film. While the creators of “The Beast” have explicitly mentioned the influence of theatre, “Gloomy Eyes” draws its visual language from similar theatrical roots. This paper argues that VR has been mistakenly compared to film and animation when it should be associated with theatre. The audience of both are not passive as they are during the screening of a film or animation. The space and the medium demands participation through their presence in the same space with the actors/characters. Theatre presents a promising candidate for extracting criteria that could be used to develop a visual language for VR. This research aims to formulate a framework for developing a VR visual language through comparison between character-driven narratives in VR such as “Gloomy Eyes” and “The Beast”. The comparative study establishes overlapping criteria and characteristics found in the structure, literacy, sound, and delivery format of narratives in a theatrical performance. These criteria are then outlined and discussed, drawing from affordance theory and discussions on aural and visual attention in theatre, to form a holistic view in approaching VR literacy.
Painting With Light: Artistic Experiments into the use of Virtual Reality as an Animation Production Environment

Published: December 2021

While many researchers have examined the technical characteristics of using VR as a production environment for animation, its artistic potential has only sporadically been investigated. We want to contribute to this line of thought through reflection on a number of expanded animation workshops organized in the context of the Painting With Light project. In this paper we use flow theory in order to discuss the experience of using VR as a 3D prototyping tool. Our findings suggest that this practice can add an improvisatory and co-creative dimension to animation.
GAMBARAN KONDISI KESEPIAN MAHASISWA YANG HANYA MENGAMBIL MATA KULIAH SKRIPSI PROGRAM PENDIDIKAN S-1 UNIVERSITAS PADJADJARAN
Authors: Herianda Ismi Putri , Wungu Esti , Dewi Rintana
Published: December 2021

Kesepian adalah kondisi yang tidak menyenangkan, subjektif, dan terjadi saat interaksi jika adanya kebutuhan dalam hubungan sosial yang tidak terpenuhi. Kesepian terbagi ke dalam dua jenis, yaitu kesepian sosial (terjadi karena hubungan pertemanan) dan kesepian emosional (terjadi karena hubungan keluarga dan hubungan percintaan). Mahasiswa Universitas Padjadjaran yang hanya mengambil mata kuliah skripsi mengalami perubahan interaksi sosial, seperti jarang bertemu dan perbedaan topik pembicaraan dengan teman yang sudah lulus maupun belum lulus, merasa tertekan oleh keluarga, dan perubahan dalam hubungan percintaan. Oleh karena itu, peneliti tertarik untuk melihat gambaran empiris mengenai kondisi kesepian yang dilihat dari kondisi kesepian sosial dan kondisi kesepian emosional pada mahasiswa tersebut. Penelitian dilakukan terhadap 330 mahasiswa Universitas Padjadjaran dengan karakteristik angkatan 2013-2015 yang hanya mengambil mata kuliah skripsi menggunakan teknik proporsional stratified random sampling. Peneliti menggunakan rancangan non- eksperimental dengan metode penelitian deskriptif dan pendekatan kuantitatif dengan menyebarkan kuesioner SELSA (Social Loneliness Scale For Adults) secara daring. Hasil penelitian memperlihatkan mayoritas mahasiswa memiliki kondisi kesepian (n = 272), kesepian sosial (n = 271), dan kesepian emosional (n = 233) pada tingkat yang rendah. Hal ini disebabkan oleh kesendirian dan sudah dapat mengatasi kesepian yang dirasakan saat sedang sendirian.

Authors: Saputra Trio , Darmawan Arief , Novaria Rachmawati
Published: December 2021

This study aims to determine the implementation of the Illegal Gold Mining (IGM) Countermeasure policy in the Kuantan Singingi Regency. This study uses a multi-sectoral multi-organizational network model consisting of a Contextual Assessment approach to understanding the environmental context and identifying stakeholders in policy implementation and joint visioning. This study critically examines the IGM in the regency in qualitative perspective from various related articles. A systematic literature review was used to analyze national and international journal articles from nine managed databases based on these concerns. From the literature review, 22 relevant research-based articles in the last 15 years from 2007 to 2020 were selected from Google Scholar, Taylor, Francis Outline, Springer Link, Emerald Insight, Science Direct, Sage Journal Online, and Oxford Cambridge. Three stages were carried out: preparation, screening and validation, and content review. The findings include 1) research showing that stakeholders involved from both government and community groups do not play an active and synergistic role in controlling IGM. 2) the implementation model of the IGM countermeasure, the government, the private sector, and the community must support each other in controlling and supervising IGM.

Ekonomiczna efektywność produkcji nasion soczewicy jadalnej (Lens culinaris Medic.)
Authors: SZWEJKOWSKA BEATA , BIELSKI STANISŁAW
Published: December 2021

Badaniami objęto dwie odmiany soczewicy jadalnej Tina i Anita, uprawiane w zróżnicowanych technologiach: nisko-, średnio- i wysokonakładowej. Zwiększenie intensywności technologii produkcji soczewicy powodowało wzrost wielkości i wartości plonu, kosztów bezpośrednich produkcji, nadwyżki bezpośredniej, wskaźnika efektywności ekonomicznej, a obniżenie jednostkowego kosztu produkcji nasion. Największy przyrost nadwyżki bezpośredniej, wynoszący średnio dla odmian 101%, uzyskano po zwiększeniu intensywności produkcji z poziomu technologii nisko- do średnionakładowej. Odmiana Anita charakteryzowała się korzystniejszymi wskaźnikami oceny ekonomicznej w porównaniu z odmianą Tina.
Plonowanie pszenicy jarej uprawianej w krótkotrwałej monokulturze w zależności od międzyplonu i sposobu odchwaszczania
Authors: GAWĘDA DOROTA , KWIATKOWSKI CEZARY A.
Published: December 2021

W dwuczynnikowym doświadczeniu polowym uwzględniono rodzaje przyorywanych corocznie międzyplonów ścierniskowych (bez międzyplonów − obiekt kontrolny, gorczyca biała, facelia błękitna, mieszanka strączkowych – łubin wąskolistny + groch siewny pastewny) oraz sposób odchwaszczania pszenicy jarej (mechaniczny, mechaniczno-chemiczny, chemiczny). Celem badań była ocena wpływu wybranych międzyplonów ścierniskowych i sposobu odchwaszczania na wielkość plonu ziarna oraz wybrane elementy plonowania pszenicy jarej uprawianej w krótkotrwałej monokulturze. Niezależnie od sposobu pielęgnacji, mieszanka łubinu wąskolistnego z grochem siewnym pastewnym powodowała istotny wzrost plonu ziarna pszenicy jarej w porównaniu z obiektem bez międzyplonu ścierniskowego, wynoszący 9,2%. Udowodniono również zmniejszenie plonu po międzyplonach z gorczycy białej i facelii błękitnej w porównaniu z obiektem z mieszanką roślin strączkowych, wynoszący odpowiednio 6,5 i 5,4%. Najwyższy plon ziarna pszenicy jarej odnotowano w wariancie z kompleksową mechaniczno-chemiczną pielęgnacją zasiewów.

Authors: PACZOS-GRZĘDA EDYTA , GRĄDZIELEWSKA AGNIESZKA
Published: December 2021

W efekcie krzyżowań międzyodmianowych, przeprowadzonych pomiędzy posiadającymi dominujący gen karłowatości Dw6 formami niskimi a liniami i odmianami wysokimi, uzyskano 147 ziarniaków reprezentujących 17 kombinacji. Mieszańcowy charakter sześciu kombinacji potwierdzał karłowy fenotyp roślin F1. Do weryfikacji pochodzenia pozostałych form zastosowano metodę ISSR. Z uwagi na wysoki poziom wykrywanego polimorfizmu metoda ISSR okazała się efektywna w identyfikacji mieszańców międzyodmianowych owsa. Ponadto spośród uzyskanych 150 polimorficznych produktów ISSR jeden (SR-37970) ulegał amplifikacji we wszystkich analizowanych formach karłowych. Produkt ten nie był powielany u żadnej z badanych roślin wysokich. Zidentyfikowany fragment po konwersji na marker SCAR może stanowić potencjalny marker dla genu karłowatości Dw6.
The effect of Fe-deficiency on antioxidant enzymes’ activity and lipid peroxidation in wheat leaves
Authors: ESFANDIARI EZATOLLAH , SABAGHNIA NASER
Published: December 2021

Studying the physiological role of nutrient elements has an unraveling capacity in understanding plant’s behavioral pattern in order to acquire a high and stable yield. For this purpose, the durum wheat variety, P1252, was selected and planted in hydroponic way. To investigate the effects of Fe deficiency, the element was eliminated from media solutions. Results showed that the lack of Fe affected superoxide dismutase (SOD), guaicol peroxidase (GPX) and catalase (CAT) activities significantly. Meanwhile, ascorbate peroxidase (APX) was the only antioxidant enzyme not shows any significant with control. The SOD/(APX + GPX + CAT) ratio as an index of assessing the balance between hydrogen peroxide (H2O2)-producing and H2O2-scavenging enzymes increased leading to the accumulation of H2O2 in cell. The elevation of SOD/APX + GPX + CAT ratio and H2O2 accumulation indicates the occurrence of oxidative stress in the leave cells in the element-deletion conditions. Other oxidative stress indices, cell death as well as malondialdehyde (MDA) did not show any significant change in the absence of Fe. The reason is assumed to be the non-occurrence of Haber-Weiss reaction in Fe absence so that hydroxyl, a very dangerous radical, is produced, leading to increased damage to cell bio-molecules and apoptosis subsequently.
Wpływ zagęszczenia roślin na plonowanie i jakość surowca nagietka lekarskiego (Calendula officinalis L.)
Authors: KRÓL BEATA
Published: December 2021

Polska zajmuje czołowe miejsce w Europie w uprawie roślin zielarskich. Jednym z ważniejszych gatunków uprawnych jest nagietek lekarski, mający szerokie zastosowanie w przemyśle farmaceutycznym, kosmetycznym i spożywczym. Celem przeprowadzonego doświadczenia było zbadanie wpływu zróżnicowanego zagęszczenia roślin (20, 40, 60 i 80 roślin na m2) na ich wybrane cechy morfologiczne oraz plony i jakość koszyczków kwiatowych nagietka lekarskiego. Najwięcej koszyczków kwiatowych (zarówno pod względem liczby, jak i masy) w przeliczeniu na pojedynczą roślinę stwierdzono przy zagęszczeniu 20 szt. · m-2. Natomiast najwięcej koszyczków kwiatowych w przeliczeniu na jednostkę powierzchni zanotowano w obiekcie o zagęszczeniu 40 szt. · m-2, w którym uzyskano także największy plon surowca. Wzrastające zagęszczenie roślin nie miało istotnego wpływu na wielkość koszyczków (z widoczną jednak tendencją do zmniejszania ich średnicy). Zwiększające się zagęszczenie roślin powodowało spadek zawartości olejku eterycznego, nie miało natomiast wpływu na poziom flawonoidów.
Wpływ warunków opadowo-termicznych na plonowanie średnio późnych i późnych odmian ziemniaka jadalnego
Authors: KOŁODZIEJCZYK MAREK
Published: December 2021

Ocenę wpływu warunków pogodowych na kształtowanie się wielkości i struktury plonu bulw ziemniaka prowadzono w latach 2006-2011. Badano sześć średnio późnych i późnych odmian ziemniaka jadalnego: Jelly, Medea, Niagara, Syrena, Ursus i Zeus. Plon ogólny bulw w poszczególnych latach badań kształtował się w szerokim zakresie od 19,1 do 66,9 t . ha-1, natomiast plon handlowy od 17,1 do 61,1 t . ha-1. Największe plony stwierdzono w sezonie charakteryzującym się nadmierną w stosunku do potrzeb ilością opadów w maju i czerwcu oraz ich umiarkowanym niedoborem w pozostałych miesiącach, najmniejsze natomiast w roku skrajnie wilgotnym. Warunki opadowo-termiczne istotnie różnicowały także strukturę plonu bulw. Niedobór opadów w maju i czerwcu wpływał niekorzystnie na liczbę bulw zawiązanych przez rośliny ziemniaka. Z kolei większa w stosunku do potrzeb ilość opadów w lipcu korzystnie oddziaływała na średnią masę bulwy. Odmiany ziemniaka istotnie różniły się wielkością plonu ogólnego i handlowego bulw, liczbą zawiązanych bulw, ich średnią masą oraz udziałem frakcji bulw handlowych i dużych w plonie ogólnym.
Charakterystyka meksykańskich genotypów pszenżyta jarego pod względem ważniejszych cech plonotwórczych
Authors: KRAMEK ANETA , KOCIUBA WANDA
Published: December 2021

. Praca miała na celu ocenę cech plonotwórczych 38 genotypów pszenżyta jarego pochodzących z Meksyku. Ziarniaki badanych obiektów wysiewane były na jednopowtórzeniowych poletkach (2 m2) w 4-letnim cyklu doświadczeń polowych w latach 2005–2008 w Gospodarstwie Doświadczalnym Uniwersytetu Przyrodniczego w Czesławicach koło Nałęczowa. W okresie dojrzałości pełnej na każdej badanej formie dokonano pomiaru wysokości roślin oraz cech plonotwórczych kłosa, takich jak: długość kłosa i liczba kłosków w kłosie, liczba i masa ziarn z kłosa, płodność kłoska, masa 1000 ziarn. Określono również zawartość białka w ziarnie badanych genotypów. Otrzymane wyniki wskazują na zróżnicowanie badanych form pod względem ważniejszych cech plonotwórczych, szczególnie liczby i masy ziarn z kłosa, na co wskazują duże wartości współczynników zmienności dla tych cech (odpowiednio: V = 12,1% oraz V = 15,5%). Istotna współzależność pomiędzy masą ziarn z kłosa i MTZ (rxy = 0,425) wskazuje, że selekcja prowadzona w kierunku dużej masy ziarn z kłosa może mieć korzystny wpływ na dorodność ziarna u pszenżyta.

Authors: Benaissa Abbes , Gaouar Soumia
Published: December 2021

In this article, we consider a Lamé system with a delay term in the internal fractional feedback. We show the existence and uniqueness of solutions by means of the semigroup theory under a certain condition between the weight of the delay term in the fractional feedback and the weight of the term without delay. Furthermore, we show the exponential stability by the classical theorem of Gearhart, Huang and Pruss.

Risks to the National Security Generated By the Widespread Use of Cryptocurrency
Authors: Bobric George-Daniel
Published: December 2021

The pronounced multi-domain technologicalization specific to the last decades has had a significant impact on all areas of activity, including the financial one. The use of cyberspace to facilitate the actions undertaken in the monetary activity has generated the development of this field to the point where virtual currencies have been created and new technologies have been developed to support their use. Like any emerging domain, the cryptocurrency field and the related technology are in a relatively early stage and exclusively imply operating in cyberspace, thus generating security risks in the event of the involvement of malicious entities in illicit activities. In this context, it is worth analyzing how the improper use of the crypto domain can lead to various risks to national security.
Packing and Unpacking Grammar – Towards a Communicative Approach to Teaching Language Structures
Authors: Dragomir Isabela-Anda , Niculescu Brânduşa-Oana
Published: December 2021

Creating classroom activities which really get students to communicate in a natural and meaningful way remains a timely challenge when it comes to teaching a foreign language. This article sets out to revisit the traditional trifecta based on the three Ps (presentation, practice, production) and reincorporate it in a set of specific elements that ensure a successful outcome of language learning activities. With particular focus on grammar, the paper aims to deconstruct the steps and procedures behind five important aspects to be taken into consideration when planning and conducting activities that target structures of language and their practice in a communicative manner, with the ultimate goal of linking the often sterile theory of grammar with contextualized models and tasks.
Equal Opportunities Through Education
Authors: Marcu Maria
Published: December 2021

An inclusive society is a society that offers its members equal opportunities to participate in all aspects of public life, without discrimination, by exercising rights and assuming responsibilities so that progress is equally desired by the individuals and the society to which they belong. The human personality is formed by the interaction of the biological (heredity) with the factors of the social environment and under the influence of education. That is why it is necessary for education to be a modeling continuum, a process that begins in the family and is continued in school, the nucleus around which the free, independent, creative personalities of future adults will be formed. Today’s children are tomorrow’s adults, the ones who will make their mark on the future society. Whether tomorrow’s society will be an inclusive society or whether it will raise barriers and generate hostility depends on how we form the young generation today. This exploratory research, based on the analysis of official documents, statistics and concrete data of the observed reality, highlights important aspects regarding the access to education of disadvantaged groups, in a society that wants to be inclusive.
Physical Activities and their Characteristics During Pandemic Times
Authors: Martinescu-Bădălan Fabiana
Published: December 2021

In this paper we wanted to present some aspects and characteristics observed in the specialized works and from the experience gained in performing physical activities during the COVID-19 pandemic. This period was a complicated one both in terms of physical distancing and emotionally. We no longer had the right to leave our houses, except to get what was strictly necessary, not to meet with family members or friends, cultural and sports activities were suspended, and all this caused an increasingly visible state of sedentary lifestyle. All the restrictions of this period had a negative effect mainly on the brain and the dynamics of the human body, and they are detailed in the following pages.
Automatic Identification of Products – A Way of Streamlining the Logistical Support of the Military Unit
Authors: Pînzariu Sorin
Published: December 2021

The new products provided by the development of information technology (scanners, barcodes, RFIDs, etc.) can currently provide methods and techniques towards achieving important savings in terms of management of logistical support of military units, especially in terms of efficiency in providing material goods to combat forces that are preparing and training through military exercises. I set out to make an “x-ray” of this way of improving the logistical support, especially through the method of identification by labels that use radiofrequency (Radio Frequency Identification/RFID).
The Impact of Some Emerging Technologies in Modern Military Actions
Authors: Raţiu Aurelian , Roşu Onisim
Published: December 2021

Among the emerging technologies, artificial intelligence represents nowadays an area of interest for all of the states around the world, making the technological progress a huge step in human evolution. The future role of the man in military actions will not be to fight in the field anymore, making decisions on how and when to use the weapons in order to stop the incoming enemy while also respecting the international laws. With the help of technology, humanity could provide its much needed security and put an end to conflicts regardless of their nature, because devices are not capable of emotions and subjectivism, making them transparent and objective and transforming the decision making process into a simpler, fairer and legal action. Technology represents the future and man should adapt to it as soon as possible in order to reach the best outcomes even when it comes to war.
