Authors: Vasanthan M Vasanthan M , V. M Vinodhini , N Kasthuri
Published: January 2022

Introduction Diabetes mellitus and dyslipidemia are non-communicable diseases that can be prevented and controlled by maintaining a healthy lifestyle. Knowledge, attitude, and practice (KAP) in patients will provide information of much importance in Advocacy (to set guidelines by the Healthcare providers), Communication (increase awareness in subpopulation), and Social mobilization (improve services and expand community support). The study aimed to assess the effectiveness of an educative session on Knowledge, attitude, and practice (KAP) in patients attending a private medical college hospital on diabetes and dyslipidemia in the South-Indian population. Methodology The study was cross-sectional which included 100 patients (41 female and 59 male) of 18-50 years of age attending the hospital and the Central clinical laboratory for various disease conditions. A self-administered questionnaire on personal aspects and diabetes and dyslipidemia was collected. Result Among the study participants, 18% completed school education, 74% completed under-graduation, and 8% completed post-graduation. The frequency of livelihood showed 84% from rural and 16% from an urban background. Nearly 71% were active and 29% were sedentary performing self-activity. The source of information regarding the treatment of patients was also obtained from the patients to implement the same in advocacy. The knowledge of the study group on various aspects including the causes, symptoms, tests, complications of diabetes mellitus, lipid profile, dietary fiber, and exercises was analyzed. We found clarity of explanation about diabetes improved well after the educative session. Around 80% of responders believed that both fiber and routine exercises would contribute to preventing diabetes. Analysis of the attitude and practice revealed a significant knowledge of practicing proper diet, exercises, and routine health care after the educative session. Conclusion We conclude that healthcare providers shall focus on educating the patients according to their needs with the knowledge to have positive attitudes on healthy lifestyle practices in addition to the appropriate treatment.

Colorectal cancer (CRC) is the world’s third most cancer and the second highest mortality rate. The searching for new anti-inflammation substances with less adverse effects than aspirin for chemoprevention and adjuvant chemotherapy of CRC is running. The most notable one is fish oil containing omega 3. Kusmardi, et al. studied that industrial waste fish oil omega-3 level comes close enough to conventional fish oil industry. Study aims to reducing the level IL-6 on mice colon tissue being induced CRC using AOM/DSS by fish oil administration. Thirty male Swiss Webster mice are grouped into six treatments: positive control (aspirin), negative control (physiological saline), normal, high dose (fish oil 6mg/kgBW), medium dose (fish oil 3mg/kgBW), dan solvent control (corn oil). Colon tissue was stained using anti IL-6 antibody. Ten photos per slide were taken by microscope (400x), analyzed for the IL-6 expression by ImageJ®, and quantified for H-score. Data was analyzed using SPSS 24.0 (CI 95%) and p-value <0.05 is consider significant. Data are not normally distributed with median of 161.64 (119.4-260.67). Kruskal-Wallis test is significant in addition with Mann-Whitney test shows only high dose group has significant difference to negative control (p=0.008), medium dose (p=0.016) dan and solvent control (p=0.008). No significant difference reported between high dose and positive control group (p=0.69). High dose industrial waste fish oil can lower IL-6 expression in mice colon tissue induced CRC using AOM/DSS.
Polygon-based computer-generated holography: a review of fundamentals and recent progress [Invited]
Authors: Zhang Yaping , Fan Houxin , Wang Fan , Gu Xianfeng , Qian Xiaofan , Poon Ting-Chung
Published: January 2022

In this review paper, we first provide comprehensive tutorials on two classical methods of polygon-based computer-generated holography: the traditional method (also called the fast-Fourier-transform-based method) and the analytical method. Indeed, other modern polygon-based methods build on the idea of the two methods. We will then present some selective methods with recent developments and progress and compare their computational reconstructions in terms of calculation speed and image quality, among other things. Finally, we discuss and propose a fast analytical method called the fast 3D affine transformation method, and based on the method, we present a numerical reconstruction of a computer-generated hologram (CGH) of a 3D surface consisting of 49,272 processed polygons of the face of a real person without the use of graphic processing units; to the best of our knowledge, this represents a state-of-the-art numerical result in polygon-based computed-generated holography. Finally, we also show optical reconstructions of such a CGH and another CGH of the Stanford bunny of 59,996 polygons with 31,724 processed polygons after back-face culling. We hope that this paper will bring out some of the essence of polygon-based computer-generated holography and provide some insights for future research.
Short-distance equivalent test of acquisition, pointing, and tracking process for space laser communication
Authors: Zou Yansheng , Ke Zihao , Shao Yeding , Fan Qirun , Liu Chen
Published: January 2022

The function and performance of acquisition, pointing, and tracking (APT) for the space laser communication terminals must be characterized on the ground before the launching. However, short working distance causes the terminals to not be viewed as a point, leading to the challenge for the whole-process equivalent test. A novel equivalent test method is proposed, to the best of our knowledge, by using a narrow laser beam and the imaging relationship between two terminals. The communication terminal is transformed to a virtual point by establishing an imaging relationship between the antenna of the transmitter and the tracking detector of the receiver. Thus, the deviation angle between the optical axis of the receiver and the centroid line of two terminals can be measured accurately. Furthermore, the acquisition process of searching the small-size antenna in the receiver with an extensive coverage beam in the transmitter is replaced by searching a large receiver surface with a narrow beam. This point-searching-surface method is equivalent to the surface-searching-point method in actual space communication. With this method, two terminals spaced 5 m apart were employed to construct the short-distance verification platform, and the APT function verification and performance test were completed.
Ultra-precision turning method efficient for optical freeform surfaces with a hybrid slow–fast tool servo
Authors: Lang Changfu , Li Chuang , Fu Hang , Bo Sui , Yang Chao , Xue Changxi
Published: January 2022

The machining of freeform surfaces is a current research hotspot: A slow tool servo (STS) has limitations in machining accuracy and efficiency for large steep freeform surfaces. Most fast tool servo (FTS) tools are limited by their stroke and cannot manufacture freeform surfaces with a large sag. We propose a hybrid slow–fast tool servo method that combines STS and FTS to machine large steep freeform surfaces by decomposing the freeform surfaces and simultaneously turning efficiently with STS and FTS. Experimental studies were undertaken to fabricate a saddle surface. Meanwhile, a variable feedrates tool path was designed and applied to further improve the machining efficiency. The results show that this method can improve the processing efficiency by 47.5%. The arithmetic mean of surface roughness (Ra) is 2–4 nm, and the peak-to-valley (PV) value is 0.4780 µm at the hollows and 0.3884 µm at the swells.
Electrically tunable Goos-Hänchen shift in two-dimensional quantum materials
Authors: Shah Muzamil
Published: January 2022

We theoretically investigate the tunable Goos-Hänchen (GH) shifts in silicene subjected to an external electric field and circularly polarized light. The prominent feature of these 2D quantum materials is the tunable bandgap that can be tuned by an external electric field or by irradiating circular polarized light beam. Using angular spectrum analysis, we obtain the analytical expressions for the spin and valley polarized spatial and angular GH shifts. We find that tuneable giant spatial and angular GH shifts exhibit extreme values near Brewster’s angles and away from the optical transition frequencies in the silicene. We demonstrate that both positive and negative giant GH shifts can be achieved in the graphene family by tuning the electric field and circularly polarized light in distinct topological regimes. Due to the topological properties of these materials, the GH shift is sensitive to the coupled spin and valley indices of the Dirac fermions as well as to the number of closed gaps. We further demonstrated that topology and spin-orbit interactions play a crucial role in beam shifts and topological quantum phase transitions of the silicene can be comprehensively and efficiently probed through GH shift at the nanoscale.

The difficulty in the preparation of high-quality rare-earth-doped double-clad chalcogenide glass fiber with high absorption of pumping energy is one of the major issues in the development of mid-infrared fiber lasers. In this study, we solve this problem by changing the inner cladding structure of the fiber. The absorption efficiencies of several typical inner cladding shapes were compared and analyzed by the ray tracing method. The result shows that the hexagonal inner cladding fiber has the best absorption efficiency. For the first time, we developed an Er3+-doped Ge-Ga-Sb-S double-clad chalcogenide glass fiber with a hexagonal inner cladding via the fiber extrusion method, and experimentally demonstrated a higher absorption efficiency in the fiber compared with those in the traditional circular double-clad fibers. Such a hexagonal double-clad chalcogenide glass fiber possesses the potentials for developing high-efficiency mid-infrared fiber lasers.

Authors: Zhao Jiazheng , Zhao Yi , Ma Xiaowei , Feng Helin , Cui Rongmin
Published: January 2022

Background

Ferroptosis has exhibited great potential in the treatment of cancer and has gained widespread attention in soft tissue sarcoma (STS). The aim was to explore the immunological and prognostic significance of novel ferroptosis-related genes in STS.

Methods

We identified ferroptosis-related differentially expressed genes (DEGs) in STS to construct the networks of enrichment analysis and protein-protein interaction. Subsequently, hub genes with prognostic significance were localized and a series of prognostic and immune analyses were performed.

Results

40 ferroptosis-related DEGs were identified, of which HELLS, STMN1 EPAS1, CXCL2, NQO1, and IL6 were classified as hub genes and were associated with the prognosis in STS patients. In the results of the immune analysis, PDCD1, CTLA4, TIGIT, IDO1 and CD27 exhibited consistent intense correlations as immune checkpoint genes, as well as macrophage, neutrophil, cytotoxic cell, dendritic cell, interdigitating dendritic cell and plasmacytoid dendritic cell as immune cells. EPAS1 and HELLS might be independent prognostic factors for STS patients, and separate prognostic models were constructed by using them.

Conclusions

We recognized novel ferroptosis-related genes with prognostic value in STS. Furthermore, we searched out potential immune checkpoints and critical immune cells.

Cristo en Miguel de Unamuno
Authors: García Mateo Rogelio
Published: January 2022

El racionalismo positivista y disolvente del siglo XIX hizo mella en el estudiante de la Universidad madrileña, Miguel de Unamuno, haciéndolo incapaz para encontrar una respuesta desde la devoción cristiana, aprendida en su Bilbao natal, hasta que la crisis de marzo de 1897 le dio a conocer el vacío de su opción por lo ateo. Lo que le llevó a redescubrir el valor religioso de la existencia, pero sin incurrir en un vitalismo irracional o fideísta. Precisamente en esto consiste la originalidad de su posición, que no pocos malentienden: ni doblegarse al yugo de la lógica racionalista ni dejarse llevar ciegamente por los impulsos del corazón. Fe y razón deben enfrentarse y combatirse, porque es a través de este conflicto como se llega a una profunda reconciliación de ambas, que hallan en el misterio de Cristo, “verdadero Dios y verdadero hombre”, su paradigma de mediación.
Witnessing History: Reflections on Teaching in Turbulent Times
Authors: Bridges Shana
Published: January 2022

Prior political turmoil in the United States constituted a precarious foundation for living and teaching through a pandemic. In this essay, I contend that pandemic separation and ideological distortion have exacerbated polarization and distrust. I also consider the pedagogical implications of rising extremist discourses and conspiratorial thinking for both students and faculty. Educators must pay attention to the rising threat of extremism and consider that our students may be susceptible to radical antidemocratic ideologies as well. To conclude, I provide examples from some of my classes in the communication discipline to illustrate my approach to teaching the complicated intersections of rhetoric and reality in today’s polarized political climate.

Kajetan Kraszewski a kwestia unicka na Podlasiu w świetle Silva rerum. Wybrane problemy
Authors: Czyżewski Feliks
Published: January 2022

The article presents Kajetan Kraszewski’s opinions on the Uniate Church in Podlasie, included in his Silva rerum. The views of the author of Kronika rodzinna (Family chronicle) are confronted with the statements of the researchers (mostly historians, literary scholars and linguists) within the broad context of the political, social and cultural life of the Polish-Lithuanian Commonwealth and the partition periods. By comparing research literature and excerpts from Silva rerum, the article analyses the effects of the Union of Lublin and the Union of Brest for the peasant community of Podlasie in the 1860s and 1870s. As presented in Kajetan Kraszewski’s Kronika, the tragedy of the followers of the Uniate Church in Podlasie resulted from the social and religious conditions that fuelled the divides during the time of the Russian partition (divide et impera). Kraszewski’s Silva rerum constitutes an image of the distance with which peasants treated Podlasie’s Uniate Church members, similar to the latter’s during the “masters’” uprising of 1863 (“in the masters’ uprising – we stayed aside watching”).
Kilka uwag o języku i kontekście kulturowym Diariusza podróżnego hetmana Filipa Orlika
Authors: Walczak-Mikołajczakowa Mariola , Mikołajczak Aleksander Wojciech
Published: January 2022

The article’s subject of interest is the language of the Travel Diary written by the Cossack hetman Pylyp Orlyk from 1720 to 1732 during a trip from Stockholm to Istanbul. The article refers to the so-called “macaronisation”, i.e. the saturation of the text with Latin and/or Italian words and borrowings from other languages, typical of Polish texts of the Baroque period. A large part is devoted to Turkish words because a significant part of Pylyp Orlyk’s journey went through the lands belonging to the Ottoman Empire in the eighteenth century.
SUPERVISION FOR ADVOCACY: SUPPORTING SELF-CARE
Authors: FARKAS KATHLEEN J. , ROMANIUK JAROSLAW R.
Published: January 2022

The objective is to examine the intersection of advocacy for social change, the individual’s emotional costs of advocacy, and the use of trauma informed care in supervisory practice to encourage and support advocates and their work.  Supervision models exist, but none address the needs of advocates who might become targets for scorn and persecution. The literature on trauma informed care provides a direction to improve the support and supervision of advocates, especially those who use their personal experiences as examples in their work. We reviewed data bases and relevant literature regarding supervision and the principles of trauma informed care.  Periodical literature was reviewed for examples of those affected personally and professionally by their advocacy efforts. Review of the literature revealed little new knowledge on supervision but provided a base to apply the principles of trauma informed care to support and encourage advocacy for social change. This paper suggests the use of trauma informed care in supervisory relationships and advocacy work. This is an original approach to encourage and uphold advocates in difficult times.
RE-CLOSED BORDER AS AN EVERYDAY EXPERIENCE. EXPLORATORY RESEARCH OF POLISH-GERMAN TWIN CITIES IN THE FIRST MONTHS OF A COVID-19 PANDEMIC
Authors: FRĄCKOWIAK MACIEJ , KACZMAREK JERZY , ROGOWSKI ŁUKASZ
Published: January 2022

Borders’ closure during the COVID-19 pandemic had a particular impact on the everyday life of borderland residents. As part of the research on bordering processes carried out since a few years, during the closure of the state borders in 2020, qualitative interviews on everyday life in the COVID-19 pandemic have been conducted. In this paper, we present the results of the exploratory study on the impact of the COVID-19 pandemic on Polish-German border twin cities. We indicate at what levels borders’ closure affected the border landscape, border practices of the inhabitants of the researched territories, and their notion of the border. We also suggest how border relations were shaped due to differences in the management and perception of the pandemic situation in two countries. The results obtained indicate that the closure of borders has made life more difficult in an area under examination and has also affected the identity and specificity of the place. This issue is worth exploring further to establish the true extent of the impact of the pandemic in the borderlands.

Authors: Nafría Jiménez Beatriz , Oliveros Conejero Raquel
Published: January 2022

Objetivos

Aportar un nuevo caso de mieloma múltiple por inmunoglobulina E (IgE), isotipo muy infrecuente ya que representa <0,1% de todos los pacientes con esta gammapatía monoclonal. Destacar la importancia del estudio de proteínas con una correcta detección, cuantificación e identificación del componente monoclonal, así como las principales consideraciones a tener en cuenta en el laboratorio clínico para un adecuado abordaje.

Caso clínico

Paciente varón de 45 años que, tras presentar dolor intenso en el codo de 5 semanas de evolución, es diagnosticado de mieloma múltiple IgE-Kappa gracias a las pruebas de laboratorio, junto con el análisis radiológico y de la médula ósea. Como tratamiento, el paciente recibe un esquema de inducción quimioterapéutico antes de someterse a un trasplante autólogo de progenitores hematopoyéticos. Actualmente continúa en seguimiento.

Conclusiones

El estudio de proteínas por parte del laboratorio clínico a través del proteinograma y la inmunofijación han permitido detectar un componente monoclonal de tipo IgE-Kappa en un paciente antes de que presentara una sintomatología CRAB (hipercalcemia, afectación renal, anemia y dolor óseo) clásica asociada al mieloma múltiple, ayudando a un diagnóstico y tratamiento precoz.

Authors: Lippi Giuseppe , Salvagno Gian Luca , Henry Brandon M. , Pighi Laura , De Nitto Simone , Gianfilippi Gianluca
Published: January 2022

Objetivos

El objeto del presente estudio es resumir la variación de una amplia serie de anticuerpos contra el SARS-CoV-2 en sujetos receptores de la vacuna de mARN BNT162b2, en un periodo de seis meses.

Métodos

La población del estudio estaba formada por 84 profesionales sanitarios seronegativos al SARS-CoV-2 en situación basal (media de edad: 45 años, 53.6% mujeres), que recibieron la vacuna de mARN denominada BNT162b2. Se tomó una muestra de sangre previamente a la primera y segunda dosis de la vacuna, así como al cabo de 1, 3 y 6 meses. Se determinó el título sérico de los siguientes anticuerpos contra el SARS-CoV-2: anticuerpos totales específicos para el dominio RBD (dominio de unión al receptor), IgG contra la proteína trimérica espicular (Spike), IgG específica para el dominio RBD, e IgA contra el receptor S1 de la proteína trimérica espicular del SARS-CoV-2.

Resultados

Todos los anticuerpos alcanzaron su nivel máximo al mes de recibir la vacunación, pero disminuyeron de forma significativa posteriormente. La tasa media de decrecimiento a los 6 meses fue de −95% para IgG anti- RBD, −85% para IgG contra la proteína trimérica espicular, −73% para IgA anti-S1 y −56% para los anticuerpos totales anti-RBD del SARS-CoV-2, respectivamente. El tiempo medio para la seronegatividad fue de 579 días para los anticuerpos totales anti-RBD SARS-CoV-2, 271 días para IgG contra la proteína trimérica espicular, 264 días para IgG anti-RBD, y 208 días para IgA anti-S1 SARS-CoV-2, respectivamente. A los seis meses, la tasa de sujetos seropositivos se había reducido del 98–100% en el momento de su nivel máximo al 50–100%. La variación entre individuos, en términos de reducción de anticuerpos contra el SARS-CoV-2, a los seis meses fue del 3–44% con respecto al nivel máximo.

Conclusiones

Los resultados de este estudio serológico demuestran que el título de anticuerpos contra el SARS-CoV-2 disminuyó a los seis meses de haber recibido la vacuna BNT162b2, con un periodo medio hasta alcanzar la seronegatividad a los anticuerpos IgG/IgA de 7–9 meses, lo que evidencia la necesidad de administrar dosis de refuerzo a los seis meses, aproximadamente, de la última dosis.

As compared to conventional techniques, currently nanotechnology has gained significant attention of scientists for the development of plant-based natural nanoparticles (NPs) due to their safety, effectiveness, and environment friendly nature. The current study was aimed for development, characterization (energy-dispersive X-ray, ultraviolet-visible spectroscopy, Fourier-transform infrared spectroscopy, and scanning electron microscopy), and evaluation of the biological efficiency of black pepper (BP; Piper nigrum) fruit-based gold NPs (BP-AuNPs) through different in vitro and in vivo assays. BP extract revealed maximum antibacterial and antifungal potential against Escherichia coli (24 mm) and Aspergillus flavus (47 mm), respectively. However, BP-AuNPs (200 µg·mL−1) inhibited the urease, xanthine oxidase, and carbonic acid-II activities with a percent inhibition of 83.11%, 91.28%, and 86.87%, respectively. Further, the anti-inflammatory effect of BP extract at the dose of 100 mg·kg−1 was 72.66%, whereas for BP-AuNPs it was noticed to be 91.93% at the dose of 10 mg·kg−1. Similarly, the extract of BP and prepared AuNPs demonstrated significant (p < 0.01) sedative effect at all tested doses. The BP-AuNPs catalytically reduced methyl orange dye. Results suggest that BP-AuNPs possess significant biological activities, and further studies must be conducted to identify the probable mechanism of action associated with these activities.

Published: January 2022

An attempt was made to synthesize zinc oxide gum white nanoparticles (ZnO-GWNPs) by the greenway approach using Aegle marmelos (Bael fruit) juice extract as a capping and reducing agent. Synthesis of ZnO-GWNPs by greener approach is safer, more economical, more energy-efficient, eco-friendlier, and less toxic than chemically synthesized counterparts. The optical properties of the ZnO-GWNPs were ascertained through UV-Vis spectroscopy, Fourier Transform-Infrared (FT-IR), X-ray diffraction (XRD), High-resolution transmittance electron microscopy (HRTEM). A characteristic absorption peak at 385nm confirmed the presence of ZnO-GWNP using UV-Vis spectroscopy. FTIR spectrum revealed that the characteristic absorption peak of the Zn-O bond was observed at 467 cm-1. The XRD result for the ZnO showed the tendency of the three most intense diffraction peaks. The average crystallite size ZnO NPs at scattering angle (2θ) 22.89 and 32.15 was 39.14 and 26.08 nm and it showed the presence of miller indices of (100), (002), (101), (102) respectively. The EDX spectrum gave strong signals for zinc and oxygen indicating the occurrence of the nanoparticles in their oxide form rather than the pure zinc form. The SEM image showed the surface morphology of ZnO-GW NPs and the HR-TEM image showed the crystalline nature of ZnO-GW NPs. Cytotoxicity study of ZnO-GW NPs was determined against MCF-7 cell lines and the IC50 values were found to be 40 µg/mL and 60 µg/mL at 24 h and 48 h respectively.

Published: January 2022

Organocatalysis has occupied sustainable position in organic synthesis as a powerful tool for the synthesis of enantiomeric-rich compounds with multiple stereogenic centers. Among the various organic molecules for organocatalysis, the formation of carbon–carbon is viewed as a challenging issue in organic synthesis. The asymmetric aldol and Michael addition reactions are the most significant methods for C–C bond forming reactions. These protocols deliver a valuable path to access chiral molecules, which are useful synthetic hybrids in biologically potent candidates and desirable versatile pharmaceutical intermediates. This work highlighted the impact of organocatalytic aldol and Michael addition reactions in abundant solvent media. It focused on the crucial methods to construct valuable molecules with high enantio- and diastereo-selectivity.

Published: January 2022

Achieving high-efficiency sorting of microfluidics (such as cells, particles, droplets, etc.) has great significance in the fields of biology, chemistry, medical treatment, material synthesis, and drug development. This paper introduces the microfluidics sorting methods in recent years. The current research status and progress can be divided into the active sorting system and passive sorting system according to whether there is an external field. They can control the microfluidics by promoting more selective separation, so as to obtain higher resolution and selection rate. In this paper, the above methods are analyzed and discussed, and the future microfluidic sorting is prospected.

Authors: Akar Alinda Oyku , Yildiz Umit Hakan , Tayfun Umit
Published: January 2022

Polyamide 6 (PA) matrix was reinforced with Na-activated bentonite, amino functional silane treated bentonite and organo-modified clays at different concentrations. The preparation of composites was carried out using melt-blending method and the test samples were prepared by injection-molding process. Mechanical, thermal, structural and processing investigations of PA based composites were reported performing via tensile, hardness, and impact tests, differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction analysis (XRD) and force measurements, respectively. According to mechanical test results, additions of fillers to PA matrix caused slight improvements for tensile strength and modulus parameters. Silane treated BNT exhibited improvement in mechanical results compared to Na-activated bentonite additions. Thermal studies revealed that decomposition and melting temperatures of PA shifted to higher values after inclusion of clay into polymer matrix. Results confirmed that organo-clay and bentonite additions with their lower filling ratios yielded enhancements for the mechanical and thermal performance of polyamide.

Jelen referátum célja az Európai Újraélesztési Társaság (European Resuscitation Council, ERC) 2021-ben megjelent(1), a periarrest időszak ellátását is magában foglaló emelt szintű újraélesztési protokolljának összefoglaló bemutatása, hangsúlyozva a korábbi, 2015-ben kiadott protokoll(2) ajánlásaitól való eltéréseket.

Az életet veszélyeztető ritmuszavarok azonnali azonosítása és kezelése alapvető jelentőségű a keringésmegállás megelőzésében, illetve ismétlődésének elkerülése érdekében. A 2021-ben, az ERC által kiadott protokoll igazán jelentős változást a periarrest  achycard ritmuszavarok ellátási algoritmusában hozott. Az ellátás főbb terápiás vonala, a korábbi guideline-nal megegyezően, továbbra is a beteg állapotának stabilitása/instabilitása alapján kerül felosztásra.

Az emelt szintű újraélesztés (Advanced Life Support – ALS) többlet beavatkozásokkal kiterjesztett alapszintű újraélesztés (Basic Life Support – BLS). Az ajánlás részletesen taglalja a kórházon belüli és kívüli keringésmegállást, az ezek ellátási lépéseit tartalmazó ALSalgoritmust, a kardiopulmonáris reszuszcitáció (CPR) során végzett légútbiztosítást, gyógyszeres terápiát és annak menedzselését.

Authors: Farkas Anett , Jávor Rebeka
Published: January 2022

Az emberek többsége úgy gondolja, hogy a fogyatékkal élőknek nincs szükségük kapcsolatra, szerelemre, érintésre, és hogy nem is képesek rá. Rengeteg tévhit kering róluk ezzel kapcsolatban, mégis kevéssé kutatott a terület, csekély szakirodalom áll rendelkezésünkre. Fontos kérdés, hogy az értelmi fogyatékkal élőknél hogyan zajlik az ismerkedés, és a család, környezet miként tud ebben segíteni. Milyen lehetőségeik vannak a párkeresésre: helyszín, társkereső oldalak, csoportok stb.? Milyen egy ilyen párkapcsolat, együtt élnek-e, ha nem, milyen sűrűn találkoznak? Mit gondolnak a nemi életről és honnan szereznek/szereztek ismereteket róla? Hogyan, miben tud a szociális segítő segíteni?
Trauma és identitás kérdései perinatális testvérvesztést átéltek narratíváiban
Authors: Bornemisza Ágnes
Published: January 2022

„A gyász annak az átérzése, hogy az elveszített személy része saját énünknek; ehhez társul annak a kínos érzése, hogy a halált saját részünk elveszítéseként éljük át” (Kovácsné Török et al., 1995, p. 243). A transzgenerációs trauma vonulata gyakran megjelenik a perinatális veszteséget átélt családok körében. Ennek a válságos élethelyzetnek a narratívája néma marad, a családtagok őrzik a titkot, mert a veszteség fájdalma megoszthatatlannak tűnik számukra. A tanulmány – rövid szakirodalmi áttekintést követően – a perinatális veszteség következtében kialakuló identitásproblémákat a túlélő testvérek narratívái elemzésének segítségével mutatja be. A szerző felhívja a figyelmet a téma további kutatásának fontosságára.
The Pinelands Development Credit Program
Authors: Howell Jordan P. , Meenar Mahbubur , Friend Christina , Kelly Jack , Feeny Owen

The “Pine Barrens” are a UNESCO-designated biosphere reserve encompassing about 1.1 million acres in southern New Jersey. A state agency, the New Jersey Pinelands Commission, in conjunction with county and local governments, works to implement land management and environmental protection goals via a comprehensive management plan. The pinelands development credit (PDC) program is one tool aimed specifically at land preservation outcomes. The PDC program is a regional “transfer of development rights” market allowing landowners to sell their rights to further develop their property and enter their land into permanent protected status. Since the program’s inception in 1982, over 55,000 acres of sensitive and rare ecosystem have been protected; the more than 1,200 transactions account for US$63 M of economic value. The PDC program is a clear illustration of the role that financial instruments and market mechanisms can play in achieving environmental protection outcomes. This case study offers an overview of the pinelands area, PDC program, and the transfer of development rights concept before examining the PDC program and its outcomes in greater detail. While the program has been hailed as a success, it will face challenges in the coming years, including a relatively inefficient process for converting PDCs into protected lands and the question of how the program can evolve once eligible lands become more scarce.
Chez Paul Niquet: Sound, Spatiality, and Sociability in the Paris Cabaret
Authors: Blaszkiewicz Jacek
Published: January 2022

Years before Montmartre’s cabarets artistiques took Europe by storm, the Cabaret Paul Niquet thrived as a Right-Bank tavern popular among Paris’s laborers, vendors, and criminals during the early nineteenth century. It became notorious not only for its clientele, but also for its vivid representations in travel literature, fiction, popular song, and vaudeville. Even after its demolition by Baron Haussmann during the Second Empire, the cabaret remained a fixation among Paris’s musical and literary class. The interest in this lowly tavern reveals a sustained middle-class preoccupation with the spatial and sonic practices of the most destitute of Parisian citizens. Yet this preoccupation was not merely a condescending fascination with the poor. Niquet’s cabaret serves as a lens through which to examine social and sensory changes brought on by urbanization. Bringing urban geography into conversation with the historiography of French theater, this article contends that the city’s proletarian leisure spaces offered a relational form of sociability that was at odds with the spectacular aesthetic of Haussmannization. The sounds emanating from Niquet’s cabaret, from clanging glasses to spontaneous songs, defined the cabaret institution spatially: not merely in acoustic terms, but also as a democratized site of leisure for workers and literati alike.
A Tale of Three Rusalkas: Krasnopol’sky, Pushkin, and Dargomyzhsky
Authors: Frainier Margaret
Published: January 2022

Conventional histories of Russian opera mark Mikhail Glinka’s 1836 opera Zhizn’ za tsarya (A Life for the Tsar) as the point of origin for Russian nationalist opera that quickly burst into full bloom, yet by the middle of the century homegrown opera had fallen out of performance repertory in favor of Western European and particularly Italian imports. It was around this time that a group of amateur composers later known as the kuchka (the “Mighty Handful” or “Mighty Five”) re-ignited the debate around creating a uniquely Russian genre of opera; however, their efforts only obscured Russian opera’s European roots rather than establish a completely separate genre. Yet their critical campaign proved successful, and the idea of Russian opera as a uniquely nationalist genre remains especially prevalent. This article examines Aleksandr Dargomyzhsky’s Rusalka (1856), one of the earliest examples of this new type of Russian nationalist opera, and how it responds to the dominance of Italian opera in Russia during the mid-century by embedding Italian operatic conventions into the score itself. Rusalka also inaugurated the operatic trend of adapting literary works by Aleksandr Pushkin, the writer often cited as the father of Russian literature. This article illustrates how both Pushkin’s dramatic Rusalka and Dargomyzhsky’s operatic adaptation of it a generation later imitated Western European literary and theatrical conventions. Paradoxically, the ways in which Pushkin and Dargomyzhsky would conceal these Western parallelisms would later be hailed as markers of a uniquely “Russian” literary and operatic style in a critical campaign designed to erase Russia’s long history of artistic dialogue with the wider Continent.
Scenes in Stone
Authors: Britt Karen , Boustan Ra‘anan
Published: January 2022

This article is the first publication, description, and identification of the floor mosaics in the north aisle of the early fifth-century synagogue in the village of Huqoq in Lower Eastern Galilee. The north aisle is arranged in individually framed panels organized in two superposed rows of nine panels each for a total of eighteen. While many are only fragmentarily preserved, each panel seems to have depicted a figure or episode from the Hebrew Bible (aside from a Hebrew-language donor inscription at the east end of the aisle). Aided by labels in Hebrew or Aramaic citing phrases from biblical verses as well as by the regularity of the overall design of the north aisle, we have been able to identify the subject matter of eight of the eighteen panels and to propose reconstructions for three others. Most significant—and surprising—among the scenes are two groups of four panels that depict episodes from the book of Daniel: the four beasts of Daniel 7 and the story of the three youths in Daniel 3. These multipanel scenes, which were placed at the west and east ends of the aisle respectively, frame the composition as a whole. Other extant panels depict a male youth leading a leashed wild animal (Isa 11.6), two spies returning with grapes from the Valley of Eshcol (Num 13.23), and the showbread table from the tabernacle (Lev 24.6). We situate the visual strategies employed in the north aisle mosaic within the development of biblical narration across a wide range of contemporaneous media. We argue that the Huqoq panels not only participated in Mediterranean-wide practices for the representation of narrative in the visual arts but also make an important contribution to our understanding of the dynamic nature of artistic exchange across the boundaries of media in Late Antiquity. Moreover, the panels provide precious evidence regarding the religious outlook, cultural orientation, and social position of the synagogue community at Huqoq. In particular, the panels depicting scenes from the book of Daniel emphasize both the threat posed by “foreign” empires to the people of Israel and their ultimate defeat at the hands of God and his warriors. This theme is likewise present in the nave and east aisle of the synagogue, especially in the Samson panels, the Crossing of the Red Sea, and the Elephant Mosaic. We suggest that these panels, taken together, celebrate Jewish heroic and even martial values that were themselves very much in keeping with the emerging ethos of imperial Christianity in the Theodosian age.
Таталiтарная эстэтыка ў беларускай паэзii (на прыкладзе творчасцi Яўгенii Пфляўмбаўм)
Authors:   Narodowa Akademia Nauk Białorusi, Minsk, Danilczyk Aksana
Published: January 2022

The problem of studying characteristics of the art of the totalitarian period remains relevant for several reasons. The first reason is the insufficient research of significant and very interesting material in the whole post-Soviet space in general and in Belarusian literary criticism in particular, the second one is a comprehensive understanding of the literary process of the 1920s and 1930s and the poet’s artistic achievements in the light of new research regarding interdisciplinary discourse that needs to be carried out. The object of the research is represented, first of all, by the works on propaganda. It is especially important to analyze them in the legacy of significant authors, one of whom is Jeugenij Pflaumbaum. In general, his work has been little studied. In J. Pflaumbaum’s works of 1928–1931, the archetypes of the hero, the father, the mother and the enemy (H. Gunther), typical of the art of new or socialist realism, are displayed.
Рамантычны фалькларызм Адама Мiцкевiча i Яна Баршчэўскага: пераемнасць i творчае развiццë (да 170-цi годдзя з дня развiтання з Янам Баршчэўскiм)

The article studies similarities and differences in Adam Mitskevich’s and Jan Barshchevski’s methods and creative approaches. Special attention is paid to folklorism in the writers’ works. The author of the article conducts a comparative analysis of Jan Barshchevski’s poem Sierota (The Orphan) and the collection of stories Szlachcic Zawalnia, czyli Białoruś w fantastycznych opowiadaniach (Nobleman Zawalnia, or Belarus in Fantastic Stories) to the poem Dziady (Forefathers) by Adam Mickiewicz. An undoubtedly successful innovation of Jan Barshchevski was the transfer of romantic folklorism into prose. This allowed the writer to create vivid and exciting pictures of life and moral world of Belarusians. The article is devoted to the 170th anniversary of Jan Barshchevski’s farewell ceremony.

In the article the works of Maxim Garetsky, a classic of Belarusian literature have been analyzed. The author directs his attention to multidimensionality, pluralism of artistic and aesthetic search, connection with existential-philosophical discourse, specificity of the writer’s approach to the essence of “existential” conflict, the problem of moral choice, responsibility for the evil. It is stated that the main line of the works is associated with the search for axiological priorities directly related to the problem of individual existence, to the option of “choice”, to the idea of preservation of human sovereignty and the protection of the right for a decent life.
Мадэрнiсцкi дыскурс у прозе Уладзiмiра Караткевiча пачатку 1960-х гадоў
Authors: Nawickaja Walentyna
Published: January 2022

The article discusses and identifies the renewal of ideological and semantic content of V. Korotkevich’s creative explorations in the early 1960s as well as an artistic-aesthethic development of his talent during studies in Moscow (1958–1960, 1960–1962). The novelty and significance of the obtained results are manifested in scientific and conceptual understanding of the peculiarities of aesthetics, characteristic to the author’s artistic thinking in “The Legend of the Poor Devil and Satan’s Lawyers” and in the novel “The Rook of Despair”. The author reveals the essence of romantic, realistic and fantastic relationships in an artistic image of reality. Not only does the author define principles of using Biblical contents and images, historical facts and literary processes in various epochs but she also recommends to reread V. Korotkevich’s books and find the writer’s understanding and artistic treatment of a Belarusian. Moreover, the author discusses the functions of intellectual aesthetics in the artistic and typological structure of the image of the impoverished Rogochev nobleman Gervasiy Vylivakha and she outlines the nature of the writer’s creative experiments, which determined the intellectual discourse in the novels “Christ landed in Gorodnya” and “Black Castle Olshansky”.
Семантический аспект понятия дом в готической литературе и его трансформация в прозе Говарда Филлипса Лавкрафта
Authors:   Białoruski Uniwersytet Państwowy Informatyki i Radioelektroniki, Mińsk, Тарасова Елена
Published: January 2022

The article examines semantic aspects of the concept of a house in Gothic literature and its transformation and comprehension by the American writer Howard Phillips Lovecraft. A house in literature is not just an architectural element, an entourage; it is a living space that determines the emotional state of characters, their spiritual and mental quest. The semantics of the word “house” is very extensive, therefore different writers (H.P. Lovecaft in particular) artfully play with meanings, offering their own original interpretations of a house.
