Tracing Beethoven in Zagreb
Authors: Bezić Nada
Published: April 2021

Beethoven’s Zagreb and Croatian acquaintances included his aristocratic friends, the two countesses, Ana Barbara Keglevich and Anne Marie Erdődy née Niczky, whom he intented to visit in 1817 in her castle near Zagreb. His other friends, Nanette and J. A. Streicher, were ancestors of today’s Zagreb musicians, and general Greth, husband of Jeannette d’Honrath, played on a private concert there in 1819. Beethoven’s music was performed on the first concert of the Musikverein in Zagreb (today Croatian Music Institute, CMI) in 1827. A representative of the Musikverein was present at the Vienna centenary celebrations of his birth in 1870; interesting material about that is kept in the CMI, together with some early and first editions of Beethoven’s works. The local premiere of the Ninth Symphony took place in 1900, with more than 200 performers. Other notable performances of the work include that conducted by Lorin Maazel (1987), and the project entitled Nine for the Ninth Centenary (1994), which united young musicians in the wartime. Tracing Beethoven in Zagreb also concerns his name, which was written on the walls of the CMI building in 1876, and his impressive bust made in 1939 by Vanja Radauš, kept today in a clinic for otorhinolaryngology.

Published: April 2021

Research about the use of Artificial Intelligence applied to journalism has increased over the years. The studies conducted in this field between January 2008 and December 2019 were analysed to understand the contexts in which they have been developed and the challenges detected. The method used consisted of a systematic review of the scientific literature (SLR) of 209 scientific documents published in the Web of Science and Scopus databases. The validation required the inclusion and exclusion criteria, database identification, search engines and evaluation and description of results. The findings indicate that the largest number of publications related to this topic are concentrated in the United States and that the rise of scientific production on Artificial Intelligence in journalism takes place in 2015, when the remarkable growth of these publications begins, until reaching 61 in 2019. It is concluded that research is mainly published in scientific journals, which include works that handle a broad variety of topics, such as information production, data journalism, big data, application in social networks or information checking. In relation to authorship, the trend is the presence of a single signer.
New technology in Museums: AR and VR video games are coming

Published: April 2021

Museums have gone through a modernization process which has seen the adoption of new technologies in what they offer visitors. Within the framework of the new critical museology, these organizations have been transformed into places of encounter and experience, the key tools in this change being socialization and play. Gamification are now intrinsic to collections and are a way of inviting visitors to share new museum experiences through the latest technology such as AR (Augmented Reality) and VR (Virtual Reality). In this way, the museum becomes a playground and a space for creativity (Borja-Villel et al., 2014). In this research, we focus on what we consider to be an important link between the three central aspects of museum change: sociability, gamificaction and virtualization; and the growing interest in museums for videogames. Our aim is to reach a better understanding of the AR and VR video games developed for museums and how these technologies can not only motivate visitors’ interest but also improve their learning skills. Our analysis focuses of literature published between 2015 to 2018 and follows the analytic structure established by Connolly et al. (2012) with additional features related to learning experience, platforms, and the use of technologies (VR and AR). The general aim is to map the interest of the research community in the field of museum-developed video games, more specifically those that use augmented and virtual reality.
Living in digital space: Everyday life on Twitter
Authors: Özbaş-Anbarlı Züleyha
Published: April 2021

New media tools and the corresponding digital networks have begun to take part in the centre of our daily lives, thereby caused a practice of everyday life in digital space. In Twitter, a network in which users are involved through the machines, the concepts such as life, time, space, rhythm have developed. This study focuses on the constitution of everyday life in digital space. Twitter is a digital space that users do their everyday life practices in this network and are involved in through the machines. A sample of 10 Turkish users was selected with social network analysis to discover everyday life practices in this digital space. The content produced by this sample was observed employing digital ethnography and analysed by the sociology of everyday life. It is observed that Twitter creates its own rhythm. Observations show in Twitter that tactics have been produced, and strategies have been tried to be turned down with these tactics and acted rhythmic practices as forms of production and consumption in everyday life. People tend to follow similar others on Twitter, and accordingly, content is being produced for an imaginary community.
Iconography of the corpse in the public sphere. Presence and absence of the dead body in times of pandemic
Authors: Benavente-Burian Fran , Fillol Santiago , Salvadó-Corretger Glòria
Published: April 2021

In this article, we examine the visual motif of the corpse and its presence in the public sphere in times of pandemic from an iconographic, political and anthropological perspective. Through the analysis of the representation of the dead body in images presented by modern media, we reflect on how the formal and iconographic schemes of presentation of death were transformed following the irruption of the Covid-19 pandemic in March 2020. The pandemic scheme, which is unusual from a political and anthropological perspective, assumes a particular approach to the problem of the representation of the dead body (anonymous body, carrier of a virus), encrypted in a dialectic between systematic omission and censorship and displacement of the representation of death towards the cumulative symmetry of empty pits or coffins that prefigure the corpse to come. Pandemic iconography, often based on science fiction imagery, outlines the dehumanized restlessness of a dystopian future. Under these exceptional conditions, some corpses, which are a priori anonymous, stand out, showing, even in the suspended space of Covid-19, the permanence of structural schemes of violence that must be denounced and fought in the present. With that in mind, we also examine the corpses claimed by Black Lives Matter and their distinctive representations, which are very different from those of the victims of the epidemic. Finally, through these references and based on the media treatment of Diego Armando Maradona’s body, we consider the significance of the return of the iconic corpse to the center of the public sphere, which imposes a regime of extreme visibility and goes beyond the representative limits of pandemic exceptionality.
Forming the Telecommunication Networks’ Cross-Sections to Analyze the Latter Stability with Different Connectivity Measures
Authors: Batenkov Aleksandr , Batenkov Kirill , Fokin Aleksandr
Published: April 2021

The problem of stability analysis and its components of reliability and survivability is quite popular both in the field of telecommunications and in other industries involved in the development and operation of complex networks. The most suitable network model for this type of problem is a model that uses the postulates of graph theory. At the same time, the assumption of the random nature of failures of individual links of the telecommunications network allows it to be considered in the form of a generalized Erdos–Renyi model. It is well known that the probability of failure of elements can be interpreted in the form of a readiness coefficient and an operational readiness coefficient, as well as in the form of other indicators that characterize the performance of elements of a telecommunications network. Most approaches consider only the case of bipolar connectivity, when it is necessary to ensure the interaction of two end destinations. In modern telecommunications networks, services such as virtual private networks come to the fore, for which multipoint connections are organized that do not fit into the concept of bipolar connectivity. In this regard, we propose to extend this approach to the analysis of multi-pole and all-pole connections. The approach for two-pole connectivity is based on a method that uses the connectivity matrix as a basis, and, in fact, assumes a sequential search of all combinations of vertex sections, starting from the source and drain. This method leads to the inclusion of non-minimal cross-sections in the general composition, which required the introduction of an additional procedure for checking the added cross-section for non-excess. The approach for all-pole connectivity is based on a method that uses the connectivity matrix as a basis, and, in fact, assumes a sequential search of all combinations of vertex sections, not including one of the vertices considered terminal. A simpler solution was to control the added section for uniqueness. The approach for multipolar connectivity is similar to that used in the formation of the set of minimal all-pole sections and differs only in the procedure for selecting the combinations used to form the cross-section matrix, of which only those containing pole vertices are preserved. As a test communication network, the Rostelecom backbone network is used, deployed to form flows in the direction of "Europe-Asia". It is shown that multipolar sections are the most general concept with respect to two-pole and all-pole sections. despite the possibility of such a generalization, in practical applications it is advisable to consider particular cases due to their lower computational complexity.
Fast pupil tracking based on the study of a boundary-stepped image model and multidimensional optimization Hook-Jives method
Authors: Grushko Yuriy , Parovik Roman
Published: April 2021

A new fast method for pupil detection and eyetracking real time is being developed based on the study of a boundary-step model of a grayscale image by the Laplacian-Gaussian operator and finding a new proposed descriptor of accumulated differences (point identifier), which displays a measure of the equidistance of each point from the boundaries of some relative monotonous area (for example, the pupil of the eye). The operation of this descriptor is based on the assumption that the pupil in the frame is the most rounded monotonic region with a high brightness difference at the border, the pixels of the region should have an intensity less than a predetermined threshold (but the pupil may not be the darkest region in the image). Taking into account all of the above characteristics of the pupil, the descriptor allows achieving high detection accuracy of its center and size, in contrast to methods based on threshold image segmentation, based on the assumption of the pupil as the darkest area, morphological methods (recursive morphological erosion), correlation or methods that investigate only the boundary image model (Hough transform and its variations with two-dimensional and three-dimensional parameter spaces, the Starburst algorithm, Swirski, RANSAC, ElSe). The possibility of representing the pupil tracking problem as a multidimensional unconstrained optimization problem and its solution by the Hook-Jeeves non-gradient method, where the function expressing the descriptor is used as the objective function, is investigated. In this case, there is no need to calculate the descriptor for each point of the image (compiling a special accumulator function), which significantly speeds up the work of the method. The proposed descriptor and method were analyzed, and a software package was developed in Python 3 (visualization) and C ++ (tracking kernel) in the laboratory of the Physics and Mathematics Faculty of Kamchatka State University of Vitus Bering, which allows illustrating the work of the method and tracking the pupil in real time.

Abstract This study aimed to evaluate the prevalence of Problematic Internet Use (PIU) among adolescents (N = 466) and its possible association with emotional problems and quality of life. Students (Mage = 12.8 years; SD = 1.9) from five public schools in a city in the State of São Paulo participated in this study and completed four instruments: a sociodemographic questionnaire; Internet Addiction Test (IAT); Depression Anxiety Stress Scale (DASS-21) and Pediatric Quality of Life Inventory (PedsQL). No significant differences were detected about the frequency and intensity of symptoms of depression, anxiety, and stress compared to those who did not have problems with the use of the Internet. No differences were observed between the groups in respect of quality of life either. However, those individuals who felt that their internet use impaired their daily activities presented higher average IAT scores and higher levels of stress. These findings indicated that the perception of internet use was the main variable associated with emotional symptoms.

Abstract The present study sought to identify the relationship between creativity and intelligence in gifted students. The sample consisted of 966 participants, aged between 7 and 17 years, classified as regular students (n=867) and criterion group (n=99), subdivided according to the area of prominence: academic (n=66), creative/artistic (n=33). The Giftedness Assessment Battery was applied to assess reasoning (verbal, logical, numerical, and abstract) and creativity (verbal and figural). The results indicated that, in the control group, the relationship between the total score for intelligence and the two types of creativity were significant and positive, and scores were higher for verbal creativity. Only the correlation between the total scores for intelligence and verbal creativity was positive and significant in the criterion group. Differences in the relationship between constructs were also found according to the identification of giftedness (academic and creative).

18. yüzyıl Klasik ekonomi politiğin modern temellerinin atıldığı ve kurumsallaştığı dönem olarak kabul edilirse, özellikle 18. ve 19. yüzyıl klasik fiziğinin iktisat üzerinde önemli etkilere sahip olduğu söylenebilir. İktisat ile Fizik bilimleri arasındaki bu tarihsel etkileşim, fizik biliminin kavramsal ve matematiksel gelişmelerinden ve doğal fenomenleri tanımlama, tahminleme ve açıklama biçimlerinin iktisat tarafından içerilmesiyle gerçekleşmektedir. Bu bağlamda son yıllarda disiplinlerarası bir alan olarak ekonofizik, fizikçiler tarafından geliştirilmiş olan yasa, teori ve metotları, belirsizlik, stokastik (olasılıksal) süreçler ve doğrusal olmayan/sapmalı (nonlineer) dinamiklere sahip iktisadi sorunların incelenmesi/açıklanması amacıyla kullanılmasına dayanmaktadır. Çalışmanın amacı özellikle gelir dağılımıyla ilgili ekonofizik çalışmalarının yöntemleri ve ortaklıklarının açıklanmasıdır. Böylece Türkçe literatürdeki bu alana dair eksiklik doldurulmaya çalışılmaktadır.

In the current study, it is aimed to improve the speaking skill of primary school students instructed in a multigrade class through cartoons. The current study employed the action research design. Participants of the study are 3rd and 4th grade primary school students instructed in a multigrade class in a village school in the city of Kahramanmaraş in Turkey in the 2019-2020 school year. The data in the study were collected through observations, interviews and documents. A program consisting of 7 applications in which cartoons are used for students with speech problems was prepared and applied within the scope of the language teaching course. The application continued for four weeks until the students' speech problems were reduced to a certain level and they achieved some improvement in speaking. Plans were prepared every week in line with the opinions of the field experts and the development status of the students in speech was evaluated. At the end of the study, the students' opinions about the application were taken through semi-structured interviews. At the end of the study, it was observed that the speech errors of the students decreased. At the same time, it was determined that there was an increase in the speaking time of the students and the number of words and sentences they used. The most important and positive change occurred in the psychological dimension of speech. Students' motivation increased and they started to behave more comfortably when speaking. In this direction, their anxiety decreased and their desire to speak increased. Furthermore, positive changes occurred in the students' adjustment of their tones and sound intensities. The words spoken by the students became more comprehensible.

Aim: To evaluate the acute and chronic effects of smokeless tobacco (ST) on the anterior segment parameters using optical biometry.
Material and Method: The comparative study included 53 right eyes of 53 subjects (study group), who used ST and 54 right eyes of 54 healthy subjects without ST (control group). Following a full ophthalmological examination, baseline measurements were taken with optical biometry and these measurements were repeated at 5, 30 and 60 mins after using ST. Central corneal thickness (CCT) (µm), anterior chamber depth (ACD) (mm), lens thickness (LT) (mm), pupillary diameter (PD) (mm), and axial length (AL) (mm) were measured.
Result: No statistical difference between the control group and study group in terms of CCT, AL, ACL and LT (p=0.771, p=0.706, p=0.546, p=0.984, respectively) however, PD values were statistically significantly different (p=0.040) in baseline measurements. In the study group, similary, no statistically significant difference was determined between the measurements taken before and after ST use in respect of CCT, AL, ACD, and LT (p=0.660, p=0.058, p=0.344, p=0.059, respectively). The changes in the PD value with the use of ST were determined to be statistically significant (p<0.01). Thus, the difference in PD value was found to be statistically significant between 5 and 30 mins, between 5 and 60 mins, and between 30 and 60 mins after ST use (p<0.01, p<0.01, p<0.01 respectively).
Conclusion: ST use did not show any acute and chronic effect on CCT, AL, ACD and LT. However, there was seen to be a significant effect on PD.
Doctrine of Frustration and Force Majeure Clause: Its Application on Tenancy Contract During the Movement Control Order in Malaysia

Published: April 2021

The government of Malaysia has declared the Movement Control Order (MCO) for the whole nation in order to flatten the curve of COVID-19 infection. The MCO has, among others, caused parties in a contract to question the effect of the MCO on the contract. As the areas of law are wide, this paper aims to discuss the effect of MCO on a tenancy contract. The paper analysed the legal position of doctrine of frustration and force majeure clause in the context of tenancy contract in Malaysia. The analysis was done based on the law cases and legal provisions in Malaysia. Reference was also made to case law from the United Kingdom and Singapore as their law is in pari materia with Malaysian law and they are persuasive in nature. This paper found that the doctrine of frustration can be invoked if the performance of the obligation under the tenancy contract is prevented due to the MCO. However, the court will apply the doctrine of frustration in a very careful manner to respect the sanctity of the agreement. As for the force majeure clause, it can be successfully invoked if the scope of the clause covers the event in question, such as the MCO. In conclusion, whether a tenancy contract can be terminated due to the MCO, it will depend on the terms of each tenancy contract.
The Application of Caveat Emptor and Caveat Venditor Doctrines from Civil and Islamic Perspectives

Since a long time ago, consumers have never been completely safe from exposure to the risk of purchasing defective products, which may cause an adverse effect on them. The introduction of the doctrines of caveat emptor and caveat venditor became a part of the common law to resolve disputes between manufacturers, sellers, and consumers. This study therefore aims to analyze the application of the caveat emptor and caveat venditor doctrines according to civil and Islamic perspectives to see how far the application of both doctrines can provide justice to consumers. Utilizing doctrinal approach based on the methodology of qualitative legal research, this study involves in-depth analysis of statutory provisions, court cases, Quranic texts, hadiths, and the opinions of Muslim scholars. The research findings were analyzed through content analysis and critical analysis methods. This study has proven that there are legal problems with regards to the application of the caveat emptor doctrine and its resulting negative impact on consumers, thus leading to the formation of the caveat venditor doctrine. Although the term “caveat venditor” and its definition are not expressly mentioned in the Qur’an and the hadiths, the application of the doctrine is seen to have a strong foundation in Islam. The results of this study are expected to contribute significant new knowledge in the field of consumer law since a comparative analysis of the application of both doctrines according to civil and Islamic perspectives is still lacking, especially in cases involving the selling of defective products.
Characteristics of telomere length in patients with hematological diseases (literature review)
Authors: Kondratieva Yu. A. , Mendeleeva L. P.
Published: April 2021

Telomeres are protein structures that regulate the process of cellular aging and play the role of a protective “cap” on the end sections of chromosomes. The telomeres of nucleated cells undergo permanent shortening during their lifetime as a result of multiple cycles of DNA replication. The enzyme that provides completion of the missing telomeric repeats at the ends of chromosomes is called “telomerase”. However, recovery of critically short telomeres by telomerase or recombination in somatic cells is limited due to the presence of a large accumulation of unclosed telomeres, which triggers apoptosis. The death of stem cells due to telomere depletion ensures the selection of abnormal cells in which the genome instability contributes to malignant progression. During carcinogenesis, cells acquire mechanisms for maintaining telomeres in order to avoid programmed death. In addition, tumor cells are able to support the telomere's DNA, counteracting its shortening and premature death. Activation of telomere length maintenance mechanisms is a hallmark of most types of cancers. In the modern world, there is an increasing interest in studying the biological characteristics of telomeres. The development of new methods for measuring telomere length has provided numerous studies to understand the relationship between telomere length of human nucleated cells and cancer. Perhaps maintaining telomere length will be an important step, determining the course and prognosis of the disease. The purpose of this review is to provide an analysis of published data of the role and significance of telomere length in patients with hematological malignancies.

Background. In present days, much attention is paid to the study of the interrelation between the macrophage/hystiocytic microenvironment and the tumor substrate in lymphoproliferative disorders.

Objective. The article is devoted to the morphometric and morphological assessment of CD163-positive macrophages in nodular sclerosis Hodgkin lymphoma.

Materials and methods. Formalin fixed, paraffin-embedded (FFPE) lymph node samples of 45 patients were used for the study. To identify and visualize CD163-positive cells in the test material, an immunohistochemical staining method was used.

Results. The study shows that the morphometric and morphological analysis of CD163-positive cells can be an effective and promising criterion for representing them as potential predictors of the disease course. Immunohistochemical study of 45 cases using the CD163 marker revealed a difference in the nature of macrophages localization in the lymph nodes nodules. The dependence of CD163-expressing cells number on the disease course was determined.

Conclusion. The data obtained can be used to stratify patients with nodular sclerosis of classical Hodgkin lymphoma into risk groups and to determine personalized approaches to treatment. Immunohistochemical determination of the CD163 marker can be used in the complex diagnosis of the causes of refractoriness to the first and subsequent lines of therapy.
