Design and modelling of all-optical NAND gate using metal-insulator-metal (MIM) waveguides based Mach- Zehnder Interferometers for high-speed information processing
Authors: Swarnakar Sandip , Reddy Siva Koti , Harijan Ramanand , Kumar Santosh
Published: April 2021

All the basic logic gates play a major role in carrying out the mathematical computation. The drawbacks of conventional electronics are alleviated by all-optical integrated circuits with a great application of high-speed computing and information processing. In this paper, plasmonic metal-insulator-metal (MIM) waveguides have an excellent property of propagating the surface plasmons beyond the diffraction limit up to deep sub-wavelength scale. All-optical NAND gate design is optimized by using MIM plasmonic waveguide-based Mach-Zehnder Interferometers (MZIs) in the footprint of 36 µm × 8 µm that works at 1.55 µm operating wavelength. The better performance of the proposed device is achieved, such as the extinction ratio is 10.55 dB, insertion loss is obtained as 0.506 dB, and response time is 262 ps. The proposed design is verified by using the finite-difference time-domain (FDTD) technique and further analysis are carried out by mathematical computation and MATLAB simulation results.

Published: April 2021

Background: This study is to investigate the effects and resistance mechanisms of first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) in non-small cell lung cancer (NSCLC) patients carrying rare EGFR exon 19 deletion-insertion (19delins) mutations. Methods: The next generation sequencing (NGS) data of 1783 patients diagnosed as advanced NSCLC from November 2017 to September 2020 were successively and retrospectively reviewed. 41 patients with EGFR 19delins and 41 patients with EGFR exon 19 deletion (19del) were enrolled in this study, who were given first generation EGFR TKIs as first-line therapy. Results: 17 mutation types of EGFR 19delins were identified in this study, L747_P753delinsS (10/41) and L747_A750delinsP (9/41) were the most frequent mutation types, followed by L747_T751delinsP (6/41) and E746_S752delinsV (3/41). Under the same baseline characteristics, median progression-free survival (mPFS) was similar in patients with EGFR 19delins to those with EGFR 19del (10.4 months vs. 13.1 months, p=0.1076). Interestingly, patients with L747_T751delinsP had a better mPFS than those with other variants (18.7 months vs. 13.1 months, p=0.035). No significant difference in mPFS was found among the three groups of gefitinib, icotinib, and erlotinb with 14.7 months, 10.9 months, and 13.1 months (p>0.05). After progression from ﬁrst-line EGFR TKIs, both EGFR 19delins and EGFR 19del had similar rates of developing resistance mechanisms including EGFR T790M mutation (45.8% vs. 57.8%). Patients acquiring T790M mutation received osimeritinib as second-line treatment, and the mPFS was similar between the groups of EGFR 19delins (n=8) and EGFR 19del (n=10): 12.0 months vs. 12.2 months (p=0.97). Conclusion: Our results indicate that patients with uncommon EGFR 19delins can also benefit from ﬁrst-generation EGFR TKIs treatment, having similar treatment responses and survival outcomes to those with EGFR 19del, even similar clinical outcomes from osimeritinib upon acquiring T790M resistance mutation.

Published: April 2021

To investigate whether pregnancy complications are associated with increased risk of UR and how that risk changes with gestational age. We obtained all data from China’s National Maternal Near Miss Surveillance System (NMNMSS) between 2012 and 2018. Poisson regression analysis was used to assess the risk of UR with pregnancy complications (preeclampsia, gestational diabetes mellitus, placental abruption, placenta previa and placenta accreta) among 9,502,250 pregnant women. Furthermore, we analyzed the risks of UR with pregnancy complications in different gestational age groups. Compared to women without pregnancy complications, those with different complications (except for preeclampsia) had a 1- to 3-fold greater risk of UR. These associations also persisted in women without previous cesarean delivery. Women with placental abruption or placenta accreta had an increased risk of UR in all gestational age groups, while the increased risk of UR among women with placenta previa was only observed at term. Moreover, an increased risk of UR among women with gestational diabetes mellitus was only observed at 32 to 36 weeks gestation and increased with the offspring’s birth weight. Better quality antenatal care and early intervention for women with these pregnancy complications are needed to minimize the incidence of UR.

Published: April 2021

The problem of stoping on ultra-long working face is one of challenges for making coal mining safe and efficient. The strong mining effect of surrounding rock induced by long working face mining causes a number of coal or rock dynamic disasters to safe and efficient coal mining. For the purpose of in-depth study of the law of earth’s surface movement on ultra-long working face, this paper, with FLAC3D (numerical simulation software) used to build a numerical model of ultra-long working face, analyzes the law of roof-to-floor strata behaviors in coal bed during mining, and studies the weakening of roof-to-floor parameters in coal bed, bearing pressure and the law of roof caving and rock strata movement; Analyzes the face length effect resulted from the difference in face lengths. It has been recognized that the sphere of influence of bearing pressure changes from small to large and then to small, and changes in distribution of arch bottom and arch height at the plastic failure zone are further intensified over advancing of the working face, moreover, the movement of rock strata is subject to the cumulative influence of the advancing direction of the working face and the face length effect. The above-mentioned research results can serve as a theoretical basis for practical engineering.

Published: April 2021

Canine parvovirus-2 (CPV-2) is an important pathogen of domestic dogs and wild canids. In Japan, CPV-2 infection remains one of the most common infection diseases among dogs. We analyzed samples collected between 2014 and 2019 to determine the antigenic variants of CPV-2 among dogs in Japan. Our results demonstrated that the CPV-2b variant was predominant. The CPV-2c variant was not found among our samples. Our findings demonstrate that the distribution of CPV-2 antigenic variants in Japan was more similar to the distribution in Australia compared with that of neighboring countries in Asia.

Published: April 2021

Machine learning techniques are commonly used to model complex relationships but implementations on digital hardware are relatively inefficient due to poor matching between conventional computer architectures and the structures of the algorithms they are required to simulate. Neuromorphic devices, and in particular reservoir computing architectures, utilize the inherent properties of physical systems to implement machine learning algorithms and so have the potential to be much more efficient. In this work, we demonstrate that the dynamics of individual domain walls in magnetic nanowires are suitable for implementing the reservoir computing paradigm in hardware. We modelled the dynamics of a domain wall placed between two anti-notches in a nickel nanowire using both a 1d collective coordinates model and micromagnetic simulations. When driven by an oscillating magnetic field, the domain exhibits non-linear dynamics within the potential well created by the anti-notches that are analogous to those of the Duffing oscillator. We exploit the domain wall dynamics for reservoir computing by modulating the amplitude of the applied magnetic field to inject time-multiplexed input signals into the reservoir, and show how this allows us to perform machine learning tasks including: the classification of (1) sine and square waves; (2) spoken digits and (3) non-temporal 2D toy data and hand written digits. Our work lays the foundation for the creation of nanoscale neuromorphic devices in which individual magnetic domain walls are used to perform complex data analysis tasks.
Protocol for Light-Dark and Activity Rhythm Therapy for sleep: Feasibility and acceptability in Schizophrenia spectrum disorders (L-DART FitSz)
Authors: Faulkner Sophie , Bee Penny E. , Drake Richard J.
Published: April 2021

BackgroundSleep problems are common in people with diagnoses of schizophrenia spectrum disorders (> 50%), even during periods of relative stability of psychotic symptoms. Evidence suggests that people living with schizophrenia spectrum disorders are often keen to improve their sleep, but few non-pharmacological sleep treatments are available to patients in specialist mental health services. It has been proposed that occupational therapists may have the relevant skills for the delivery of behavioural sleep interventions. This mixed method, proof-of-concept study aims to assess the feasibility and acceptability of a new intervention, Light-Dark and Activity Rhythm Therapy (L-DART), to improve sleep in people with schizophrenia spectrum disorder diagnoses.MethodsA single group of 10 service users with schizophrenia spectrum diagnoses and self-reported problems with sleep onset, maintenance, timing or quality will be offered L-DART. L-DART will be delivered over 6–9 in person sessions and 3–6 phonecalls by an occupational therapist. Feasibility measures will comprise recruitment and retention logs, fidelity based on session records, adverse effects, and study attrition. Intervention uptake, engagement and adherence will be measured, and barriers to adherence explored. Acceptability will be assessed though quantitative satisfaction ratings and qualitative interviews. Activity patterns and dynamic light exposure will be measured, as well as self-reported sleep, wellbeing and functioning, to inform outcome selection in a larger trial.DiscussionThe findings will inform any necessary modifications to the intervention and its materials, enabling the development of a stage 2 manual and a therapist training package. The results will support the design of a randomised multi-therapist feasibility trial.Trial registrationISRCTN11998005, assigned registration on 17.02.2020

Authors: Liang Mingming , Ding Xiuxiu , Wu Yile , Sun Yehuan
Published: April 2021

There are many studies that have explored the relationship between temperature and the spread of infectious diarrhea (ID), but the results obtained are inconsistent. It is necessary to systematically evaluate the impact of temperature on the incidence of ID. ID is an intestinal infectious disease including cholera, typhoid and paratyphoid fever, bacterial and amebic dysentery, and other infectious diarrhea. This study is based on the PRISMA statement to report this systematic review. We conduct literature searches from CNKI, VIP databases, CBM, PubMed, Web of Science, Cochrane Library and other databases. The number registered in PROSPERO is CRD42021225472. Finally, after searching a total of 4,915 articles in the database and references, a total of 27 studies were included. The number of people involved exceeded 7.07 million. The overall result demonstrated when the temperature rises, there is a significant increase in infectious diarrhea (RRcumulative=1.42, 95%CI:1.07–1.88, RRsingle−day=1.08, 95%CI:1.03–1.14). Subgroup analysis found that the cumulative effect of temperature on the bacillary dysentery group and other diarrhea groups. The result of the single-day effect subgroup analysis was similar to the result of the cumulative effect. And the sensitivity analysis proves that the above results were robust. This systematic review and meta-analysis support that temperature will increase the risk of ID, which is helpful for ID prediction and early warning in the future.
Using Patient Feedback to Adapt Intervention Materials Based on Acceptance and Commitment Therapy for People Receiving Renal Dialysis
Authors: Elander James , Kapadi Romaana , Coyne Emma , Taal Maarten , Selby Nick , Stalker Carol , Mitchell Kathryn
Published: April 2021

Background: Theory-based intervention materials must be carefully adapted to meet the needs of users with specific physical conditions. Acceptance and Commitment Therapy (ACT) has been adapted successfully for cancer, chronic pain, diabetes, irritable bowel syndrome, multiple sclerosis, and a range of other conditions, but not so far for people receiving renal haemodialysis. This paper presents findings from a study to adapt ACT-based intervention materials specifically for renal dialysis. Methods: Draft written materials consisting of four stories depicting fictitious individuals who used ACT-related techniques to help overcome different challenges and difficulties related to dialysis were adapted using a systematic patient consultation process. The participants were 18 people aged 19 to 80 years, with chronic kidney disease and receiving renal dialysis. Individual, semi-structured interviews were conducted to elicit participants’ views about how the content of the draft materials should be adapted to make them more realistic and relevant for people receiving renal dialysis and how the materials should be presented and delivered to people receiving renal dialysis. The interview transcripts were analysed using a qualitative adaptation of the Delphi method in which themes are used as a framework for translating feedback into proposals for modifications.Results: The analysis of patient feedback supported the use of patient stories but suggested they should be presented by video and narrated by real dialysis patients. They also indicated specific adaptations to make the stories more credible and realistic. Participant feedback was translated into proposals for change that were considered along with clinical, ethical and theoretical factors. The outcome was a design for a video-based intervention that separated the stories about individuals from the explanations of the specific ACT techniques and provided greater structure, with material organised into smaller chunks. This intervention is adapted specifically for people receiving renal dialysis while retaining the distinctive theoretical principles of ACT.Conclusions: The study shows the value of consulting patients in the development of intervention materials and illustrates a process for integrating patient feedback with theoretical, clinical and practical considerations in intervention design.

The effect of temperature (60, 70, 80 and 90 ºC) and time (30, 45, 60, 75 and 90 min) on citric acid extraction of Haden mango ( Mangifera indica L . cv. Haden) peel pectin was evaluated in the present study. In order to obtain a better understanding of both the extraction process and the characteristics of the pectin (obtained from an agro-industrial waste) for a future scaling process, the following characterizations were performed: 1) Kinetic, with the maximum extraction times and yields at all evaluated temperatures; 2) thermodynamic, obtaining activation energies, enthalpies, entropies and Gibbs free energies for each stage of the process; 3) physicochemical (chemical analysis, monosaccharide composition, degree of esterification, galacturonic acid content, free acidity, Fourier-transform infrared spectroscopy, thermogravimetric and derivative thermogravimetric analyses) and; 4) economical, of the pectin with the highest yield. The mango Haden peel pectin was found to be characterized by a high-esterified degree (81.81 ± 0.00 %), regular galacturonic acid content (71.57 ± 1.26 %), low protein (0.83 ± 0.05 %) and high ash (3.53 ± 0.02 %) content, low mean viscometric molecular weight (55.91 kDa) and high equivalent weight (3657.55 ± 8.41), which makes it potentially useful for food, pharmaceutical and environmental applications such as delivery system, gelling agent or as an emulsifier.Statement of NoveltyThe novelty of this work lies in the valorization of an agro-industrial waste (Haden mango peel) through the kinetic, thermodynamic, physicochemical, and economic characterization of a product obtained (pectin). This work contributes to laying the groundwork for an industrial scale-up for pectin production in a mango processing industry.

Published: April 2021

Background

Spinal Cord Injury ( SCI ) is a disease leading to permanent neurological dysfunction. In recent years, exosomes and non-coding RNAs have been considered as potential therapeutic agents for spinal cord injury. Based on ceRNA regulatory network, the role of non-coding RNAs has been paid attention to, and some genes related to the pathological process after spinal cord injury have been found. However, most gene studies only focus on exosomes and non-coding RNAs in spinal cord injury sites, and few genes related to spinal cord injury repair have been found.
Objective

We aimed to identify exosomes and non-coding RNA in peripheral blood after spinal cord injury, and to predict its role in spinal cord injury according to gene expression profiles.
Materials and methods

After successful modeling of spinal cord injury, rat exosomes were extracted from peripheral blood.Western-Blot was used to identify exosomes. After RNA was extracted from exosomes, total transcriptome sequencing and differential gene GO and KEGG Pathway analysis were performed. We selected potential genes for quantitative Real-Time PCR (qRT-PCR) assays and predicted their potential regulatory networks.
Results

The successful establishment of spinal cord injury model was confirmed by Tarlov’s scores, and the extracted exosomes were confirmed by Western-Blot and electron microscopy. Among the significantly differentially expressed lncRNAs, XR_351404, XR_353833, XR_590719, XR_590076, and XR_591455 were associated with miRNA related to repair after spinal cord injury.
Conclusions

The regulatory effect of this network may play a key role in the repair process of SCI. The differential lncRNAs we found may serve as therapeutic targets and diagnostic biomarkers for SCI.
Model Test and Theoretical Analysis of New and Old Embankments Differential Settlement Considering Lateral Deformation
Authors: Lv Gao-hang , Cui Wei , Wang Shu Jian
Published: April 2021

In the embankment widening project, the new embankment will produce large deformation due to the low degree of consolidation, which will affect the stability of the embankment. Obtaining the settlement law of embankment is the premise to ensure the stability of the embankment. In this paper, the deformation law of the new embankment is studied through the embankment model test, and the settlement calculation method of the new embankment is proposed. The model test results show that the new and old embankments have a large settlement difference during the loading process, and the maximum settlement of the new embankment is twice that of the old embankment. The lateral deformation of the new embankment is directly proportional to the vertical deformation, sliding occurs under the ultimate load, and the bearing capacity is lost. Based on the one-dimensional calculation method, the lateral deformation coefficient is introduced, and the two-dimensional embankment settlement formula is obtained. The new embankment is meshed, and the deformation of each node is calculated by the formula, and the difference between the settlement and the model test data is 6.2%, which proves the feasibility and accuracy of the calculation method.

Background

Hypoxia-activated prodrugs (HAPs) are a promising class of antineoplastic agents that can selectively eliminate hypoxic tumor cells. The present study evaluates the hypoxia-selectivity and antitumor activity of CP-506, a DNA alkylating HAP with favorable pharmacological properties.
Methods

Stoichiometry of reduction, one-electron affinity, and back-oxidation rate of CP-506 were characterized by fast-reaction radiolytic methods. In vitro, 2D monolayer and 3D spheroid and multicellular layer cultures were used to investigate the hypoxia-selectivity of CP-506. In vivo, the causal relationship between tumor oxygenation and antitumor effects of CP-506 was assessed. Mice bearing a range of human tumor xenografts were exposed to CP-506 and tumor growth was monitored. A multivariate linear regression model was used to identify factors associated with CP-506 treatment outcome.
Results

Net reduction, metabolism, and cytotoxicity of CP-506 were maximally inhibited at oxygen concentrations above 1 µM (0.1% O2). CP-506 demonstrated cytotoxicity selectively in hypoxic 2D and 3D cell cultures with normoxic/anoxic IC50 ratios up to 203. In vivo, the antitumor effects of CP-506 were selective for hypoxic tumor cells and causally related to tumor oxygenation. CP-506 effectively decreased the hypoxic fraction and inhibited growth of a wide range of hypoxic xenografts. Two well-oxygenated models were refractory to treatment despite intrinsic anoxic sensitivity in vitro. A multivariate regression analysis revealed baseline tumor hypoxia and in vitro sensitivity to CP-506 to significantly correlate with treatment response.
Conclusions

Our results demonstrate that CP-506 selectively sterilizes hypoxic tumor cells and has broad antitumor activity. Our data also indicate that tumor hypoxia and cellular sensitivity to CP-506 are strong determinants of the antitumor effects of CP-506.

Authors:   Irkutsk National Research Technical University, Wei Zhang
Published: April 2021

The article presents the conditions that contribute to the development of an organizational and economic mechanism. The article reveals the need to implement pilot programs to support export enterprises and successfully implement reforms in the field of foreign trade. In modern realities, the formation of the mechanism will contribute to the optimization of processes in the business environment, and the revival of the market, which should have a positive impact on the pace of international development. Integration of industries and cluster development, according to the authors, will accelerate the pace of high-quality development. From the point of view of foreign trade stabilization, the highest priority for further deepening of reforms is a sharp reduction of government costs in import and export relations in order to increase the competitiveness of foreign trade. Further cost reduction is aimed at meeting import and export requirements and facilitating cross-border trade. It is proposed to use the advantages of the new customs, deepen reforms, simplify customs clearance procedures, reduce the volume of import and export documents, apply a “single window” in international trade, as well as reduce port, inspection and quarantine fees. At the same time, it is important to pay attention to the time and cost of certification of compliance and compliance with borders. The creation of free trade zones as the core, and the deepening of market reforms, which will affect the qualitative construction of a market system with high standards and further optimization of the business environment. The use of the main results of the study in practice contributes to the development of a model of the organizational and economic mechanism for the development of exports to the domestic market. The findings will allow us to develop an effective strategy for the sustainable development of export enterprises not only in the domestic market, but also in the external one
Franz Boas’ Postulate of the Warfare Origin of Secret Societies and Myths about the “Culture Heroˮ and the “Tricksterˮ in North America
Authors: Molnar Dragana Jeremić , Molnar Aleksandar
Published: April 2021

In this paper, the authors argue that Franz Boas had a coherent theory of the secret society, which he did not systematically develop anywhere, but which can be reconstructed from several of his works. The authors are not dealing with the whole theory, but only with the postulate of the warfare origin of secret societies (which later became the foundation of the Männerbund theory). Namely, Boas believed that the secret societies of the North American Indians were originally warlike, but that by the beginning of the 20th century they either retained only the functions of initiation and education, or were transformed into therapeutic and dance societies. Although he claimed that the mythology of the Indians did not provide additional insights into the origins of secret societies, his dealings with the myth of the “culture heroˮ and the “tricksterˮ proved the contrary. The authors try to go a step further and find new contributions for the study of the origins of secret societies in North America in the myth of Wolf as the brother (father) of the “culture hero.ˮ
Models of Boys’ Gender Socialization in Families in Modern-day Serbia
Authors: Ćeriman Jelena
Published: April 2021

This paper focuses on the process of gender socialization of boys, examined through parenting practices of mothers and fathers in the contemporary socio-cultural context of Serbia. The analysis is based on empirical material collected via semi-structured interviews during 2012 on a sample of 24 families with children aged 2 to 12. The constant comparative analysis (grounded theory method) includes attitudes and actions of parents of boys and girls (as a control group) in the process of family gender socialization, and enables interpretation of boys’ gender socialization models on a continuum ranging from traditional to modern upbringing practices of parents. The research shows that parental practices in modern-day Serbia are still primarily traditional. Of the three distinct models of boys’ gender socialization (traditional, transitional and participatory), the last two represent a step forward in the direction of the individualization of parenthood and more egalitarian gender socialization patterns influenced primarily by partner relationship dynamics. These dynamics are initiated by mothers’ reflexiveness and the transformation of the concept of the “sacrificing motherhood”. The dynamic of partner relationships thus shifts in the direction of “sacrificing fatherhood”, that is, a father’s renunciation of a part of the privileges he enjoyed before entering the responsibilities within the household. Interactions with the social environment (and perceived changes in it), as well as interactions with the family of origin are crucial elements in whose interrelation the upbringing practices of parents are built and within which gender socialization of boys takes place in the socio-cultural context of contemporary families in Serbia.
Theories of The Origin of The Septuagint
Authors: Kubat Rodoljub
Published: April 2021

In this paper the author presents and critically assesses scholarly theories tackling the issue of the Septuagint's origin. The most prominent theories shape the course of research into the Septuagint's origin. The basic questions which these theories aspire to answer are: the wayof emergence of the translation, the reason for, and the origin of the translation, and the place of its origin. There are two basic theories dealing with the way of emergence of the translation: these are the Urtext theory and the Targum theory. The first one still represents the basis of textual criticism methodology. Other theories predominantly tackle the question of what led to the translation in the first place. Two most dominant theories in this respect are the theory of liturgical use and the theory of codification. The former is more widely spread and has its different variations. The third question focuses on the location of the translation. Historical sources and the majority of scholars claim that the translation originated in Alexandria. One of the opposing theories claims the Judaean origin of the Septuagint. There is a significant number of opinions which fit somewhere in between the two. At the very end of the paper two research principles (criteria) have been more thoroughly investigated and presented. The first - internal criticism is based on the analysis of the translation itself, while the second deals with the research of external sources which can shed additional light on the topic.
Is the Consumer's Voice Heard at All: Economic and Cultural Mediation Between Industry, Trade and Consumption (1945-1961)
Authors: Velimirović Danijela
Published: April 2021

The introduction of socialism entailed a fundamental reconstruction of bourgeois trade, which was labelled as "profiteering", "speculative" and "black marketeering". Alternative new trade, based on "sound and nationwide" foundations, was supposed to successfully link production and consumption through the planned distribution of goods, thus contributing to general prosperity and a happier future. However, the introduction of self-management in 1950 revitalized the principle of supply and demand and decentralized supply. The stated aim of the new regulations and the newly introduced control bodies was to establish ethical, efficient and "more civilized" trade, and to satisfy consumers' needs and wants. Although trade was assigned the role of mediator between production and consumption, research shows that in the course of the "social life" of things, a mutually constitutive relationship between industry, trade and consumers was being established, by means of which multiple "mediation regimes" were effectuated (Cronin 2004). While the first half of the 1950s was marked by trade interventions seeking to redefine the design and quality of manufactured goods, the second half of the decade saw a new departure. Industry, aided by designers as professional interpreters of consumer markets, sought to influence commercial buyers' choices with a new supply of goods aligned with consumers' wants. Through legislative acts which enabled the establishment of a consumers' council, direct mediation of consumers' needs and wants was also legitimized. These multidirectional cultural and economic mediations between industry, trade and the consumer were successful to a lesser or greater extent. Admittedly, in certain economic situations, both trade and industry used their capacity for blackmail to protect their guild interests. The hidden mechanisms of influence and power inhibited the mediating action of various actors and contributed to systemic confusion. However, it is indisputable that representatives of industry and trade as economic and cultural actors, together with consumers, sought to channel wants into economically presented forms of demand, and to gradually deconstruct the mechanisms of "dictatorship over needs" characteristic of socialist economies.
Human-Animal Relations at the Center of Attention: A Chance/Case Study of Serbia
Authors: Žakula Sonja
Published: April 2021

In late 2018 and early 2019, the city of Belgrade was host to as many as four different exhibitions with the topic of human-animal relations. The fact that these exhibitions were held in such a short time in a city the size of Belgrade is in itself interesting, seeing as the topic of human-animal relations is still not part of the academic and artistic mainstream globally, let alone in Serbia. The themes and messages of these exhibitions seem even more relevant with regard to the current global situation. Thus, the two main goals of this paper are: 1. to point out the importance studying human-animal relations in the social sciences and the humanities can have for the understanding of different economic, political and ideological assemblages of the anthropocene that make human civilization, seemingly apart from nature, susceptible to catastrophes such as the current COVID-19 global pandemic – through the analysis of the contents of the exhibitions and the panel discussions that accompanied them; 2. to indicate the welcome rise in interest in issues of human-animal relations evident in both the general public and academic and artistic contexts in Serbia. The paper offers an analytical overview of the contents of the of Animals and Humans, Covoyagers, Instinct and Terrain and Emil/Specimen B5044 exhibitions, the ensuing discussions with the public and some of the main issues raised within these discussions such as the issue of responsibility humans have toward other species we share the planet with, as well as the issue of the accountability of big polluters, which is often swept under the rug through the utilization of discourse on the impact of Man – with a capital m – on the environment. The paper also emphasizes the importance of these topics for life in the anthropocene, and calls attention to the emergent interest in human-animal relations and innovative theoretical approaches to them in Serbian academia, especially in ethnology and anthropology and archaeology.
Humour and Antiquity in Film: Roman Scandals and Monty Python’s Life of Brian
Authors: Stevanović Lada
Published: April 2021

Antiquity appears in films from the very beginning of cinema. As in other examples of reception, the presence of antiquity depends on the context of reception, the specificity of the medium which includes the relationship with the audience, as well as the personal mark of the author. The subject of this paper are two movies set in antiquity: Roman Scandals (1933) and The Life of Brian (1977). Both films are comedies, the plots of which are set in the ancient past, and both are satirical, meaning that they have a contemporary social sting. Also, both comedies belong to the genre of swords and sandals (if we take this as an umbrella term for all films related to antiquity, and not only the epic sagas of the mid-1950s and 1960s), revealing a similar, parodic attitude to the mentioned genre. The film Roman Scandals, a musical comedy with elements of burlesque, is set both in contemporary America (the midwestern city of West Rome) and ancient Rome, constructing the complex process of identification and differentiation with ancient Rome. All this has to do with the remarkable usage of Rome in American culture and history, especially since the time when America started to break ties with Britain. This is explicitly marked in the scene of the exhibition in the Museum of Rome, which, as it is emphasized, belongs to the period of the Roman invasion of Britain. Humorous twists are numerous, being constructed in language, in problems of adaptations and dialogues between cultures, and in the parody of the genre and its motifs. The Life of Brian also parodies the genre of swords and sandals and its subgenre – biblical and Christian movies. Although both films are set in antiquity, the humorous procedures construct the satirical tone, which always bears a contemporary social sting. The anachronisms, and overlapping of history and contemporariness are constructed differently in those two films. However, they both raise, among other things, a question crucial for the research field of classical reception (to which this paper belongs), and that is the way in which antiquity is used in the invention of tradition (Hobsbawm). The paper also gives attention to the genre of parody, which already appeared in antiquity, continuing its existence through the Middle Ages, especially regarding the sacred texts and forms which, according to Bakhtin, all had their parodic version. In view of the fact that both films construct humour in numerous ways, the paper focuses particularly on the humorous procedures set in the context of antiquity, which among other things, raises the question of the attitude towards antiquity that these films pose.
The Search for Identity: An Anthropological Interpretation of Engaged Research in Paštrovići and the Use of the Concept of Intangible Cultural Heritage for Identity Political Purposes
Authors: Rašić Miloš
Published: April 2021

Paštrovići is the name of a clan and of an ethnographic area of the Montenegrin coast stretching from Čanj to Bečići and from the Adriatic Sea to Crmnica. I visited this region twice, in 2017 and 2018, as part of the Etno Lab project, directed by the Bauo Society for Cultural Development from the town of Petrovac by the Sea, with funds and other forms of assistance provided by the Municipality of Budva, the Ministry of Culture of Montenegro, and several local families. The purpose of the stay in Petrovac was engaged field research with the aim of exploring the "traditions" and cultural heritage of Paštrovići, with the intention of mapping potential elements for inscription on the list of Montenegrin intangible cultural heritage. In this paper, I start from the hypothesis that the organization of Etno Lab, the directing of research and, finally, the search for identity markers with a view to having them recognized as important and inscribed on relevant lists by the national state, are precisely a form of reflection of the socio-political identity turmoil which is primarily occurring at the political level in the nation state of Montenegro and then spilling over into social reality, where it assumes various forms. Thus, the paper is divided into four sections: a brief overview of socio-political changes in Montenegro; a discussion of the methodological procedures used in our research and their inadequacies; an anthropological interpretation of the concept and a search for elements of intangible cultural heritage in relation to the identity political uses of the given phenomena.
The Amateur Basketball Team of the Multinational Company Ernst Young in Belgrade as a Folklore Group
Authors: Dražeta Bogdan , Dražeta Lazar
Published: April 2021

The subject of the analysis of our paper is the social and cultural practice of amateur basketball played by employees of the multinational company Ernst Young in Belgrade. We observed the amateur team as a folklore group, and their participation in sports is interpreted not only as a physical activity, but as a modality of shaping attitudes, values and beliefs related to the company, important for strengthening cohesion among employees and reinforcing their motivation to perform work tasks. Basketball as a sport in which each player aligns on an individual level with the collective strategy of the team is somewhat reminiscent of the activities of Ernst Young employees, such as teamwork, personal and professional development, as well as an organizational culture oriented towards the company’s development and growth on the market. The material in this paper was collected using the technique of semi-structured interviews with members of the amateur basketball team Ernst Young, which competes in the Rekreativ League of Belgrade and is composed mainly of employees in this organization. In addition to this base of our ethnographic material, informal interviews were conducted and employee statementsobtained. Using the concept of idioculture of the American sociologist, social psychologist and folklorist Gary Alan Fine, the material related to the creation, expression and subsistence of the group’s identity (composed mostly of amateur basketball players) was analyzed and interpreted. Members of this sports community differentiate themselves from other employees in the multinational company through the mentioned group identity. The group is recognized as such by other employees in this organization, which was shown by further analysis performed in accordance with the theoretical and methodological framework of the “folklore diamond” established by Gary Alan Fine. However, Fine himself never applied this framework consistently according to all its elements of analysis. The selection of these elements is made with regard to what is being examined, hence Fine’s “folklore diamond” is used as a source from which analytical concepts are taken and combined. The cultural context, as another element, gives a more complete picture of the overall analysis. This gives us an impetus for further ethnological and anthropological research of amateur sports in Serbia, especially in the corporate work environment.

The debate persists about the inflammatory or tumoral, benign or malignant nature of the Inflammatory myofibroblastic tumors (TMI). Radioclinically, they can mimic a malignant neoplasm, although they are classified as intermediate by the World Health Organization (WHO). The diagnosis is almost always made by pathological examination. The treatment is poorly codified but the management is usually surgical. The removal of these tumors is a challenge when the mass is developed at the expense of or in the vicinity of noble organs. Several therapies have been tested to overcome the limitations of surgery, the results are variable. These tumors rarely affect the digestive tract. We propose the study of a case of myofibroblastic tumor developed at the expense of the omentum, five months after a cesarean section, in order to try to determine if it is a rare complication of the postpartum or a fortuitous combination.
