Algoritmo para Cálculo da Similaridade Semântica entre Nomes de Conferências Cadastradas no Curriculum Lattes e na Base Qualis
Authors: Soares Rafael , Frantz Rafael Z.
Published: February 2021

A Plataforma Lattes é um ambiente no qual os pesquisadores registram dados relacionados às suas atividades acadêmicas, dentre elas as publicações em periódicos e eventos. No Brasil, esses periódicos e eventos podem ter um indicador de avaliação conhecido como Qualis. A automatização da extração de dados de publicações de periódicos do currı́culo Lattes e a obtenção do Qualis correspondente é uma tarefa trivial graças ao uso do ISSN como chave de identificação. No entanto, quando se trata de artigos publicados em eventos, a única chave de identificação disponı́vel é o nome do evento, o que dificulta essa busca. Neste artigo, propomos um algoritmo para uma comparação eficiente de sentenças e o aplicamos na comparação de nomes de eventos para que seja possı́vel buscar com o máximo de assertividade o Qualis para as publicações em eventos registradas em um currı́culo.

Published: February 2021

Linha de Produto de Software (LPS) é uma abordagem de reuso de software que vem se consolidando na indústria e na academia no decorrer dos últimos anos. No entanto, a ausência de ferramentas que ofereçam suporte à modelagem de LPSs baseadas em UML e controle sobre as principais atividades no ciclo de vida de uma LPS, motivaram o desenvolvimento do ambiente SMartyModeling. A arquitetura do SMartyModeling foi instanciada a partir da VMTools-RA, uma Arquitetura de Referência para ferramentas de variabilidade de software, adaptando suas visões e elementos para o contexto de LPS. Como uma forma de evoluir o ambiente criado, foram realizados testes exploratórios. Assim, este artigo apresenta o planejamento e a execução de testes exploratórios na SMartyModeling, a partir do ponto de vista de um testador que não participou do processo de desenvolvimento do ambiente. Foram discutidos os 12 defeitos resultantes desses testes, descrevendo o contexto em que foram identificados e se, até o momento, foram corrigidos. Os defeitos foram também categorizados pelas funcionalidades do ambiente, explicando sobre a importância de expandir para novos testes que permitam um ambiente mais confiável.

A Unified Feature Model for Scrum Artifacts from a Literature and Practice Perspective
Authors: Garcia Luciano A. , OliveiraJr Edson , Leal Gislaine Camila L. , Morandini Marcelo
Published: February 2021

Scrum has become one of the most popular Agile methods. Among its main elements are its artifacts. These artifacts are related to the requirements required for the software and how they will be worked on during a Scrum interaction called Sprint. Given the importance of artifacts in the Scrum structure, evidence of the adaptations of these artifacts was collected with the aid of a systematic mapping study and a survey literature with practitioners of the method. Later, we systematized the evidence of adaptations found and built models of features in order to register them and enable users of the methods to have a broader understanding of the features that Scrum artifacts can assume.

Published: February 2021

Information and communications technologies promote change in the service sector, and the banking sector is not an exception. Finding what factors impact consumer satisfaction with service and lead to loyalty is invariably important for business. However, it is important to begin with evaluating the aspects that are specific to the market and service. The purpose of this study was to investigate the factors affecting customer loyalty in Mobile Banking. Following the model designed by the researchers, consideration was given to mediator variables of satisfaction, trust, and customer service to examine how factors such as perceived risk, relative advantages, and usability affect customer loyalty. In this study, customers of an Iranian bank (Shahr Bank) based in the city of Tehran constituted the statistical population. The descriptive survey method was used on a sample that was selected through a cluster-convenience method and included 411 Shahr Bank's customers resident in the east, west, north, south, and centre of the city of Tehran. Structural Equation Modelling (SEM) test and the LISREL 8.8 software were used to analyse the data and to determine what role each factor plays on loyalty. The results showed that such factors as relative advantages, satisfaction, and trust have the most significant impact on customer loyalty. However, the effect of usability on customer service was not confirmed. Furthermore, it was identified that perceived risk has a negative impact on loyalty.
Elterliche Selbstbestimmung im Kinderschutz
Authors: Beckmann Janna
Published: February 2021

Die Arbeit befasst sich umfassend mit der Bedeutung elterlicher Selbstbestimmung bei Interventionen im Kinderschutz. Grundlage der Arbeit ist im Rahmen einer Untersuchung von Art. 6 Abs. 2 GG eine verfassungsrechtliche (Neu-)Bewertung des Eingriffscharakters von Interventionen – neben klassischen Wächteramtsmaßnahmen wie Sorgerechtsentzügen insbesondere auch von Hilfen hinsichtlich ihres Zustandekommens sowie ihrer Inhalte – sowie der Legitimationsschwelle für Eingriffe. Ausgehend von der These, dass die allgemeine Eingriffsschwelle eine (drohende) Verletzung des Kindeswohls ist, während Eingriffe, die mit einer Trennung des Kindes von den Eltern verbunden sind oder eine solche verfestigen, nur unter der zusätzlichen Voraussetzung einer nachhaltigen Kindeswohlgefährdung legitimierbar sind, untersucht die Verfasserin die einfachgesetzliche Ausgestaltung und ihre Praxis sowohl im Bereich des Jugendhilfe- als auch des Familienrechts. Die Untersuchung zeichnet sich durch die Einbeziehung ethischer und sozialpädagogischer Aspekte sowie durch den Versuch aus, eine Einordnung für die schwierigen Abwägungsentscheidungen in der Praxis vorzunehmen. Die Verfasserin leitet die Abteilung „Rechtsberatung, Rechtspolitik, Forschung“ im Deutschen Institut für Jugendhilfe und Familienrecht (DIJuF).

Published: February 2021

Uterine leiomyomas are one of the most common diseases in women. However, there is still much about them we do not know. These tumours, also known as fibroids or myomas, affect women mainly during their reproductive years, and they are diagnosed in up to 70% to 80% of women during their lives. The most relevant part of this disease is the profound impact in the quality of life of women, in the provision of health services, and on the costs all around the world. Even though, the majority of women with fibroids are asymptomatic, approximately 30% of them will present severe symptoms, with a broad range of problems such as: abnormal uterine bleeding, infertility, and obstetric complications. There are multiple factors involved in the biology of fibroids: genetic, epigenetic, hormonal, proinflammatory, angiogenic and growth factors, growth factors that are capable of inducing and promoting de development of fibroids. The leiomyoma is surrounded by a pseudocapsule generated by compression and ischaemia of the tumour towards the myometrium and is composed by multiple elements that that promote healing and tissue repair of the myometrium after myomectomy. Therefore, its conservation in the myometrium is essential, regardless of the surgical technique used. Resection by hysteroscopy can be performed in an office or in an operating room, depending on the characteristics of the fibroid, it is required a good diagnosis and experience.
Brain Functional Architecture and Human Understanding
Authors: M. Yufik Yan
Published: February 2021

The opening line in Aristotle’s Metaphysics asserts that “humans desire to understand”, establishing understanding as the defining characteristic of the human mind and human species. What is understanding and what role does it play in cognition, what advantages does it confer, what brain mechanisms are involved? The Webster’s Dictionary defines understanding as “apprehending general relations in a multitude of particulars.” A proposal discussed in this chapter defines understanding as a form of active inference in self-adaptive systems seeking to expand their inference domains while minimizing metabolic costs incurred in the expansions. Under the same proposal, understanding is viewed as an advanced adaptive mechanism involving self-directed construction of mental models establishing relations between domain entities. Understanding complements learning and serves to overcome the inertia of learned behavior when conditions are unfamiliar or deviate from those experienced in the past. While learning is common across all animals, understanding is unique to the human species. This chapter will unpack these notions, focusing on different facets of understanding. The proposal formulates hypotheses regarding the underlying neuronal mechanisms, attempting to assess their plausibility and reconcile them with the recent ideas and findings concerning brain functional architecture.

Authors: Nleya Thandiwe , Bhattarai Dwarika , Alberti Phillip
Published: February 2021

Camelina (Camelina sativa L. Crantz,) a new oilseed crop in the Brassicaceae family has favorable agronomic traits and multiple food and industrial uses. Appropriate production practices for optimal camelina yield in temperate climates of North America are lacking. This study investigated the response of camelina seed yield and quality, and agronomic traits to applied N (5 levels, 0, 28, 56, 84, 140 kg ha−1) and four seeding rates (4.5, 9, 13, 17.5 kg ha−1). Separate experiments were conducted at four environments (site-years) for N and three environments for seeding rate in South Dakota. In three of the four environments, the highest N rate increased seed yield by 30 to 60% compared to the control. The increase in seed yield with increasing N rate was linear in a high yielding environment and quadratic in a low yielding environment. Increasing seeding rate increased plant stands but had inconsistent impacts on seed yield depending on location and year. Seed oil concentration ranged from 149 to 350 g kg−1, was inversely related to N rate but was not influenced by seeding rate.
Onshore? Offshore? How about Firm Coherency?
Authors: António Mexia Arraya Marco
Published: February 2021

Investments in offshore or onshore can be directly linked to improvements in firm performance, whether the measure is costs, sales revenues, profits, or stock market returns. However, what allows firm improvement is the combination of leadership, human capital, corporate strategy, resources, capabilities, and an offering of products or services that create value and a coherent system. This coherence is the basic principle that allows to generate growth opportunities, respond flexibly and capture the opportunities quickly, and creating value for the customers profitably. A survey can be used to check firm coherency assessment and its fitness for offshore or onshore investments. There is no one-size-fits-all approach to choose where to invest, and the management practices that have the biggest impact on performance will depending on geography, culture and local resources. Thus, an evaluation of firm coherency is essential. Managers can use the survey in this chapter to quickly assess their firm’ coherent strengths and weaknesses for offshore and onshore investments.
Endoscopic Ultrasound Assessment of the Duodenal Wall Lesions
Authors: Seicean Andrada , Rednic Voicu , Seicean Radu
Published: February 2021

Subepithelial tumors (SETs) in the upper digestive tract are rare and only 10% of are located in the duodenum. Assessment of lesions protruding from the duodenal wall is difficult. Upper gastrointestinal (GI) endoscopy and computed tomography (CT) are not able to completely distinguish between different tumors and guide their subsequent management. Endoscopic ultrasonography (EUS) has a significant diagnostic yield in this context. EUS is able to accurately diagnose duodenal lesions, perform a biopsy if considered useful, guide the approach for resection and provide appropriate follow-up. SETs reported during upper GI endoscopy are more commonly cysts, polyps, lipomas, Brunner’s gland adenoma, ectopic pancreas, gastrointestinal stromal tumors (GISTs) or neuroendocrine tumors (NETs). In addition, although more rarely, adenocarcinomas and lymphomas can be identified. EUS should be performed for any duodenal lesion larger than 1 cm that lacks the endoscopic characteristics of a cyst or a lipoma.

Published: February 2021

Pregnancy in autoimmune rheumatic diseases remains a real challenge in clinical practice due to complex interplay between disease activity, pregnancy and drugs, and account for potential influence of pregnancy on rheumatic condition and the impact of disease on pregnancy outcomes. Indeed, innovative and successful therapies have dramatically improved the quality of life in immune-mediated rheumatic conditions and, subsequently, allowed more patients of reproductive age to plan a pregnancy/to conceive. The purpose of this chapter is to discuss emerging data about the interaction of pregnancy and systemic erythematosus lupus (SLE) focusing on modulation of the immune system by pregnancy, pregnancy outcomes in women with active lupus, biomarkers of adverse pregnancy outcomes (APO) including predictors of pre-eclampsia, predictors of obstetric complications in SLE, the influence of autoantibodies on fetal health, and, finally, evidence about rheumatologic and obstetric follow-up. There are still unmet needs in this new field of reproductive rheumatology and it becomes crucial that researchers, physicians (rheumatologists, specialists in maternofetal medicine, obstetricians) and midwifes share their knowledge and expertise in counseling women with SLE wishing to conceive, assisting pregnancy and managing different issues related to APO as well as drug optimization in preconception, during pregnancy and postpartum period.

Published: February 2021

Click chemistry involves highly efficient organic reactions of two or more highly functionalized chemical entities under eco-benign conditions for the synthesis of different heterocycles. Several organic reactions such as nucleophilic ring-opening reactions, cyclo-additions, nucleophilic addition reactions, thiol-ene reactions, Diels Alder reactions, etc. are included in click reactions. These reactions have very important features i.e. high functional group tolerance, formation of a single product, high atom economy, high yielding, no need for column purification, etc. It also possesses several applications in drug discovery, supramolecular chemistry, material science, nanotechnology, etc. Being highly significant and valuable, we have elaborated on several aspects of click reactions in organic synthesis in this chapter. Recent advancements in the field of organic synthesis using click chemistry approach have been deliberated by citing last five years articles.
Endothelial Dysfunction and Systemic Inflammation in the Pathogenesis and Progression of Portal Hypertension
Authors: Curakova Ristovska Elena
Published: February 2021

Hepatic and extrahepatic factors contribute to mortality related to liver cirrhosis and therefore much research is still to be done in order to understand the condition thoroughly and to possibly intervene in the process. It is considered that the currently applied prognostic scores are not ideal mortality predictors. On the other hand, recent scientific concepts have revealed the significant contributing role of endothelial dysfunction and of systemic inflammation in the pathogenesis of portal hypertension. Consequently, these concepts are inevitably leading towards proposing and validating new prognostic indicators in cirrhotic patients. Von-Willebrand factor as an indicator of endothelial dysfunction and C-reactive protein as a surrogate marker of systemic inflammation and several other parameters and biological markers have been emerging as a relevant and potentially useful prognostic indicators. Also, the coagulopathy associated to liver disease is in close relation with these entities and still an important research topic. Despite the promising data regarding their prognostic potential, additional research is needed in order to define and validate their value more precisely in clinical and prognostic settings.

Authors: V. Pereira Robson , E. Gallina Thais , A. Pereira-da-Silva Marcelo , S. Freitas Kênia , J. de Menezes Aparecido
Published: February 2021

Cellulose is considered one of the most important renewable sources of biopolymers on Earth. It has attracted widespread attention due to its physical–chemical characteristics, such as biocompatibility, low toxicity, biodegradability, low density, high strength, stability in organic solvents, in addition to having hydroxyl groups, which enable its chemical modification. In this study, cellulose nanofibrils (CNFs) were functionalized with dicyanovinyl groups through nucleophilic vinylic substitution (SNV) and used as electrocatalyst in electrochemical of carbon dioxide (CO2) reduction. Results indicate that introducing dicyanovinyl groups into the structure of nanocellulose increases electrocatalytic activity as compared to that of pure nanocellulose, shifting the onset potential of the electrochemical CO2 reduction reaction to more positive values as compared to those for the reaction with argon. The atomic force microscopy (AFM) images show no changes in the morphology of CNFs after chemical modification.
Refocusing Functional Anatomy and Immunology of the Respiratory Mucosa in the Advent of Covid-19
Authors: Simukoko Humphrey
Published: February 2021

Atmospheric oxygen is an indispensable element required in order for mammalian cells to function normally. The mammalian respiratory system, through pulmonary ventilation and gas diffusion, provides the physical mechanisms by which oxygen gains access to all body cells and through which carbon dioxide is eliminated from the body. The network of tissues and organs of the respiratory system helps the mammalian body cells to absorb oxygen from the air to enable the tissues and organs to function optimally. The advent of the coronavirus disease 2019 (Covid-19) Pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has stimulated heightened and refocused interest in the study of various aspects of the respiratory system. The SARS-CoV-2 targets the respiratory system mucosal cells and in a cascade of biological processes curtails the ability of the respiratory system to absorb and deliver oxygen to the pulmonary blood and body cells often resulting in severe disease and/or death. The mucosa and submucosa of the respiratory tract are adapted to provide both innate and adaptive immune defense mechanisms against pathogens including the SARS-CoV-2. The entire respiratory tract is covered by a mucosa that transitions in its structural and functional characteristics from the upper respiratory tract to the lower respiratory tract. This chapter provides an overview of the functional anatomy and immunology of the respiratory tract covering the mucosa from the upper respiratory tract all the way up to the alveolar epithelium. In the advent of the covid-19 pandemic, a broader perspective and understanding of the anatomy and immunology of the respiratory tract will enable general readers and researchers to fully appreciate the discourse in covid-19 research as it affects the respiratory tract.
Preparing Practice-Based Researchers for Diverse Classrooms: A Pathway for Teacher Education
Authors: Lammert Catherine
Published: February 2021

Twenty-first century educators are faced with new dilemmas, as well as new opportunities. In response to the increasing racial, cultural, and linguistic diversity of students, some school districts and states have implemented policies mandating particular curriculum. However, evidence increasingly shows that teachers who are effective in diverse classrooms are adaptive and responsive rather than strictly adhering to scripted curriculum. One proposed solution is preparation to conduct practice-based research as part of teaching. Practice-based research is a method of studying ones’ own teaching that draws on action research, design-development research, and transformative research. As a method through which teachers define questions, explore solutions, and share successes in professional communities, practice-based research holds tremendous potential to support teachers in diverse classrooms as they work to teach in culturally sustaining ways despite external pressures. This chapter begins with the history of action research and the tradition of teachers conducting research on their practice. Then, examples of practice-based research in literacy teacher education settings from a review of the research literature are provided to demonstrate the challenges, opportunities, and design features for this work. The chapter concludes with recommendations for teacher education policies, for teacher educators, and for practice.

Authors: Ravara Ascensão , Wiklund Helena , Cunha Marina R.
Published: February 2021

Eight species of Ophryotrocha and one of Parougia were identified from organic substrata (wood and alfalfa) sampled at the Gulf of Cadiz and Western Iberian Margin (NE Atlantic). Morphological examination and molecular phylogenetic analyses, based on the nuclear gene H3 and the mitochondrial gene 16S, indicate the presence of four species new to science: Ophryotrocha chemecoli sp. nov., O. nunezi sp. nov., O. geoffreadi sp. nov. and Parougia ougi sp. nov. The geographic and/or bathymetric distribution is extended for four previously known species: O. cantabrica, O. hartmanni, O. mammillata and O. scutellus. Another species may also have its distribution extended, pending the molecular confirmation of its identity: O. lipscombae. Full descriptions and figures are given for all the new species and, when justified, also for the previously known ones. The original description of O. scutellus is amended. New DNA sequences are given for eight of the nine species studied here. The ecology and geographic distribution of the reported species is discussed.
Identification of Paraproteins via Serum Immunofixation or Serum Immunosubtraction and Immunoturbidimetric Quantitation of Serum Immunoglobulins in the Laboratory Testing for Monoclonal Gammopathies
Authors: Mrosewski Ingo , Urbank Matthias
Published: February 2021

Context.—

In laboratory testing for monoclonal gammopathies, paraproteins are identified via serum immunofixation or serum immunosubtraction, and immunoturbidimetric quantitation of serum immunoglobulins is often used.

Objective.—

To evaluate methodologic differences between serum immunofixation and serum immunosubtraction, as well as in the quantitation of serum immunoglobulins on different clinical chemical platforms.

Design.—

Three hundred twenty-two unique routine patient samples were blinded and used for comparison between serum immunofixation on Sebia's HYDRASIS 2 and serum immunosubtraction on Sebia's CAPILLARYS 2, as well as between quantitation results of immunoglobulin A, G, and M on Abbott's ARCHITECT c16000PLUS and Roche's Cobas c 502 module. Microsoft Excel 2019 with the add-on Abacus 2.0 and MedCalc were used for statistical analysis and graphic depiction via bubble diagram, Passing-Bablok regressions, and Bland-Altman plots.

Results.—

The median age of patients was 75 years, and samples with paraproteinemia were nearly evenly split between sexes. Paraprotein identification differed remarkably between immunofixation and immunosubtraction. Quantitation of serum immunoglobulins showed higher values on Abbott's ARCHITECT c16000PLUS when compared with Roche's Cobas c 502 module.

Conclusions.—

Identification of paraproteins via serum immunosubtraction is inferior to serum immunofixation, which can have implications on the diagnosis and monitoring of patients with monoclonal gammopathy. If immunoturbidimetric quantitation of immunoglobulins is used for follow-up, the same clinical-chemical platform should be used consistently.

On ethics of psychological and psychiatric testifying
Authors: Vučević Zoran , Biro Mikloš
Published: February 2021

Giving two examples from their own practice and by developing a theoretical debate about the relation of law and moral, the authors point out the neglect of ethical questions in psychological and psychiatric court testifying. The authors emphasize the situations in which a court expert while testifying presents some facts about the accused which are morally or socially unaccepted, as well as the situations when a court expert presents up to that moment unknown facts which may charge one of the sides in the trial. So, by doing that, the expert automatically takes side of the other one in the trial.

Authors: Zogić E.H. , Glogić E.R.
Published: February 2021

Let G be a simple graph with vertex set V = V(G) = {v1, v2,..., vn} and edge set E = E(G). For vi ∈ V(G), by di = di(G) we denote the degree (number of neighbors) of the vertex vi. The second Zagreb index is defined as M2(G) = ∑ vivj∈E(G) didj. In this paper, we study the minimal and maximal second Zagreb index of trees with fixed diameter.

Let G = (V,E), V = {v1, v2,..., vn} be a simple connected graph with n vertices, m edges and a sequence of vertex degrees d1 ≥ d2 ≥ ··· ≥ dn > 0, di = d(vi). The general sumconnectivity coindex is defined as Ha(G) = ∑i j (di + dj) a , while multiplicative first Zagreb coindex is defined as P1(G) = ∏i j (di + dj). Here a is an arbitrary real number, and i j denotes that vertices i and j are not adjacent. Some relations between Ha(G) and P1(G) are obtained.
Educational implications of 'six thinking hats'
Authors: Bosanac Maja , Grandić Radovan
Published: February 2021

Modern education is increasingly linked to market principles. On the one hand, proponents of this approach emphasize the need to develop an entrepreneurial mindset, while critics point out that this approach neglects the humanistic dimension of education. The goal of the paper is to set up a "six thinking hats" learning model as a way to encourage the development of creative thinking. Although its primary use is in non-formal education (creative training and interactive workshops), this model also has its application within the academic community. Within formal education, the authors advocate the possibility to widespread the application of this model, technique, or role-playing game as it is called by different authors, which points to the pluralism of approaches. Also, the analysis of the studied literature revealed the application of the model at different levels of education. In conclusion, it is stated that although it is not a conventional and widely accepted model, it can be a good way to foster creative and entrepreneurial thinking. The application of this model is recommended for teachers who find the traditional approach to teaching rigid and who are ready for changes that involve a more active pupil/student role.
Motor skills of primary school children: The differences compared to age

Physical education, from the earliest age in preschool institutions, and then through primary and secondary schools, is the only place where children can, in the right way, acquire the knowledge on sports, skills, behaviour, necessary in order to get the continuity of physical activities in the adulthood. Primary school is a period when the students experience great changes in the overall developing status. Therefore, Physical Education has a fundamental role in the development of psychosomatic characteristics of children. While planning lessons of Physical Education, there is a special emphasis on the development of motor skills. The goal of this research refers to the establishing of the existing differences in the motor space of primary school children in relation to age. The sample consisted of 231 examinees who attended 3rd, 4th, 5th and 6th grade (age 11 ± 1.6 years), out of which there were (N = 109; TV = 147.6 ± 7; TM = 39.6 ± 7.1) boys, and (N = 122; TV = 148.3 ± 5.9; TM = 40 ± 5.3) girls. All examinees were the students from the territory of Zlatibor region and with the signed permission for performing testing by both parents. Motor skills have been estimated within school Physical Education, all with the purpose of getting more realistic picture on the motor skills of children. The presented results point to the existing differences between the groups of examinees of both genders on a general level, as well as the individual differences within the motor space. These differences are more noticeable with boys (F = 5.92; P = .00) than with girls (F = 4.79; P = .00). Statistically greater differences with boys have been noted in the following variables: "Hand tapping", "Hand clapping", "Throwing basketball ball", "the 30 m running flying start", "Pull-ups", and "Torso lift-ups". With girls, statistically significant difference have been notes in the following variables: "Throwing basketball ball", "the 30 m running flying start" and "Torso lift-ups". The value of this work is reflected in the fact that, during testing, a great number of tests were used for estimation of the examinees' motor space, all with the purpose of getting more complete picture on the existence of differences among the groups, categorised by gender and age. The importance of testing and perception of differences in motor skills and their monitoring presents one of the important activities during PE classes, all with the purpose of the adequate lesson programming, but also monitoring the motor development.
Digital violence and the role of different factors in its prevention and sanction in Serbia

Published: February 2021

The appliance of many new technologies brought many benefits to modern society. Modern life is, generally, easier, faster and risen at the much higher level. The speed of modern technology use is such that it is almost impossible to have a complete view-only the benefits of modern technologies are noted. Mobile phones, laptops, tablets, drones, Internet, Facebook, Skype, 5 G network and many other examples of new technology application have lots of benefits. But, have these technologies started to be used with taking into account the potential by bad consequences that they can have? Can all potential by bad effects and consequences of modern technology use be predicted, analyzed and prevented? The main goal of this paper was to confirm and present that the increase of digital violence caused by usage of modern technologies and to show factors that are included in children protection from digital violence in Serbia. Research presented in this paper were realized by the author of the paper as longitudinal research for several years in several elementary and secondary schools in Nib, so as some research from world prove that increased use of modern technologies inevitably leads to digital violence, primarily among school age children. The paper also presents the role of different instruments in digital violence prevention and sanction in Serbia. Digital violence indeed presents a bad consequence of modern technologies and must be treated in appropriate pedagogical and legal way.
