Foucault e a Filosofia
Authors: Gonçalves Victor ,   Philosophy Documentation Center
Published: November 2021

Michel Foucault was a persistent, although sui generis, reader of Kant, and that is the appropriation that we will analyse. We will Start by the extensive introduction that he has made for his translation of Anthropologie in pragmatischer Hinsicht, where he shows the failure of the kantian pragmatic anthropology. We will proceed with the study of the kantian criticism in Les Mots et les Choses, which set the conditions to the transition of the Classic to the Modem episteme, allowing nevertheless, and simultaneously, the creation of a new metaphysics out of the representations and forming a philosophy obsessed by man, by means of reducing his field of knowledge to the “empiricisms” of life, of language and of work. Nietzsche will come in his help by offering, with the “disappearance of man”, the promise of the renaissance of philosophy. Finally, in a third part, we will reflect on the way Foucault commits himself more directly to the Kantian reception, by enlarging and renewing it through the importance he gave to the “diagnosis of actuality” and to the “ontology of ourselves”, instead o f the “analytics of truth”, as well as to the axiology of revolution. This was already present in the texts he wrote in the 80’s about Was ist Aufklärung? and Der Streit der Facultäten, there defining much of his own condition as a public and private thinker.

Authors: Pimentel César , Rodrigues Francisco , Madruga João , Elias Rui
Published: November 2021

O Graben das Lajes localiza-se na vertente Nordeste do vulcão dos Cinco Picos, entre a escarpa das falhas das Fontinhas, a Sudoeste, e a de Santiago a Nordeste. Do ponto de vista hidrogeológico esta zona está associada ao troço mais oriental do aquífero de base da ilha Terceira, recarregado, em grande parte, nas zonas centrais da ilha onde a precipitação é mais elevada. Para além do aquífero basal o Graben das Lajes comporta duas massas de água subterrâneas suspensas localizadas a profundidades distintas. Na zona litoral Sudoeste do Graben das Lajes existem três zonas lagunares associadas a descargas das massas de água acima referidas - os pauis da Praia da Vitória, do Belo Jardim e da Pedreira do Cabo da Praia. Estas massas de água superficiais têm particular importância ecológica, dada a sua grande biodiversidade. Na determinação do estado trófico dos três pauis foram utilizados dados da concentração de fósforo total cedidos pela Camara municipal da Praia da Vitória no âmbito do Projeto LIFE CWR, entidade responsável pela gestão destas zonas húmidas. Utilizando o fósforo como variável dependente, foi aplicado o índice do estado trófico de Lamparelli (2004). Quando aplicado o índice trófico aos três pauis, verificou-se que, entre 2016 e 2017, todos se encontravam num estado predominantemente eutrófico. Palavras-chave: Trófico; Fósforo; Proveniência.
Desenvolvimento e validação de aplicação computacional para avaliar Sistemas de Rega Sob Pressão
Authors: Brito da Luz Paulo , Felicíssimo Diogo , Carriço Nelson , Antunes André
Published: November 2021

O setor do regadio requer práticas com sustentabilidade ambiental e competitividade socioeconómica, que envolvem o incremento do uso eficiente da água, em diferentes escalas e redes de distribuição. Muitas abordagens inovadoras para apoiar essas práticas, nomeadamente as que se relacionam com as tecnologias de informação e comunicação (TIC), são presentemente inseridas e divulgadas na designada “Agricultura 4.0”. Neste sentido, ao nível da rede terciária, as TIC têm melhorado a capacidade de se transferir e utilizar informação, facilitando ao regante a abordagem de diferentes processos relativos às instalações de rega, desde a fase de compra até avaliações de desempenho, entre outros. Na generalidade dos projetos hidroagrícolas em Portugal, a opção dos regantes por métodos sob pressão (i.e. rega por aspersão e localizada) tem crescido face a vantagens de automatização, economia de mão-de-obra e de maior eficiência no uso da água. Contudo, continuam a observar-se situações de risco na gestão dos recursos naturais e energéticos, pela falta de adequação do sistema de rega às condições pedo-climáticas específicas das parcelas. Consequentemente, um sistema de rega sob pressão pode atingir níveis de classificação de desempenho muito baixos, considerando as perdas de água excessivas, relacionadas com os escoamentos (superficiais e/ou subterrâneos), a evaporação e os desvios causados pelo vento. Estas perdas podem ser calculadas pela Eficiência de Aplicação, que é definida pela razão entre o volume médio de água disponível para as plantas e o volume médio aplicado na rega. Este indicador depende de determinadas variáveis com impacto mais significativo que se relacionam com: 1) tipo e características da rega: dotação, taxa de aplicação; 2) características do terreno: textura do solo, declive e coberto vegetal; e 3) fatores climáticos: velocidade do vento e temperatura. O presente artigo tem como objetivo a apresentação de uma aplicação computacional desenvolvida e validada para o cálculo da eficiência de aplicação de água de sistemas de rega sob pressão, ao nível da rede terciária (parcela). Esta ferramenta de AgriTech processa classificações e padrões devidamente enquadrados em informação e recomendações de normalização atualizada, capacitando o utilizador para fazer as opções mais válidas com base em critérios objetivos de boas práticas. Palavras-chave: Aplicação computacional; Boas práticas; Eficiência de aplicação; Rede terciária; Sistemas de rega.
Green criminology - revisiting: Reflections, connections, horizons
Authors: Nigel South
Published: November 2021

This paper traces aspects of the development of a 'green' criminology. It starts with personal reflections and then describes the emergence of explicit statements of a green criminological perspective. Initially these statements were independently voiced in different parts of the world but they reflected shared concerns. These works have found unification as a 'green', 'eco-global' or 'conservation' criminology. The paper reviews the classifications available when talking about not only legally - defined crimes but also legally perpetrated harms, as well as typologies of such harms and crimes. It then looks at the integration of 'green' and 'traditional' criminological thinking before briefly exploring four dimensions of concern for today and the future.
The influence of criminal career on the manner of perpetrating street robbery
Authors: Banović Božidar , Braković Žarko
Published: November 2021

Street development is a form of development and content of all elements of a significant criminal offense and was committed against one or more persons, who walked, known or unknown to the executor, performed in public places that should become proposed, parks, public garages, entrances and stairs in residential buildings, etc.). They belong to the more frequent types of robbery, characterized by less sophistication in execution and direct confrontation that determines the quantity of fear suffered, the scope and intensity of the studied consequences. The aim of the research was to examine the influence of the previous experience of the perpetrators of the robbery on the way of choosing the victim, the place of victimization and the presence of other persons who would be in the immediate or close environment of the street robbery victim. The sample consisted of 42 respondents who committed street robbery out of 120 examined perpetrators of the crime of robbery and serious cases of robbery and robbery, who were serving a prison sentence in the penitentiary in Sremska Mitrovica. Data were collected through an anonymous survey. The results show that there will be differences in the approach to victim first choice, place of execution, internal and external presence of others, between executor who have already and those who have no previous experience in development research. The executors of robbery who have already committed this act are not more inclined to type a potential victim, but they would rather decide to immediately commit a street robbery by encountering a victim with whom the "prey" is visually noticeable. When choosing the place where the crime was committed, they are more inclined to emphasize the possibility of safe removal, but they are more inclined to say that when they commit the crime at night, it will still be in a place that is not lit. Experience predisposes them to pay less attention to the external presence of other persons, while perpetrators who commit robbery for the first time give priority to victimization when the victim is alone. Proper understanding of these indicators can contribute to the qualitative improvement of the analysis, which will facilitate our identification of key starting points in the selection of the best solutions for effective intervention, in order to reduce street robberies.
Public prosecutor's decision not to conduct criminal prosecution and to abandon criminal prosecution: Introduction of the ruling of abandoning criminal prosecution
Authors: Vuković Nikola
Published: November 2021

In preliminary proceedings, for which for the purposes of this paper we mean part of the procedure in which authority conducting proceedings is public prosecutor, prosecutor's offices in Serbia have been making decisions for ten years that according to the CPC they can not make. First, decisions of dismissal of criminal complaint are made when the prosecutor, after undertaking criminal prosecution in preliminary proceedings for criminal offences for which a fine or a term of imprisonment of up to eight years shall be prescribed as the principal penalty, determines that there is not a sufficient degree of probability that the defendant committed the crime. Second mistake is the decision of dismissal of criminal complaint in a situation when the criminal proceedings began by the issuance of a ruling ordering detention before submitting a motion to indict in summary proceedings. The third mistake is issuing an order discontinuing the investigation after the conclusion of the investigation. In the first and third case, a decision to abandon criminal prosecution should be made and in the second case, the public prosecutor should submit a statement of abandoning criminal prosecution to the judge for the preliminary proceedings after which that judge will issue a ruling discontinuing criminal proceedings.
Violation of labour rights and social security rights: The problems in practice and the need for revision
Authors: Stevanović Aleksandar
Published: November 2021

The aim of the paper is to determine the main characteristics of the crime in question. It was pointed out that this is a criminal norm that provides protection to labor relations in a general way, i.e. workers' rights. Therefore, there are numerous ambiguities in judicial practice, mostly concerning the legal qualification of the violation of labor regulations and issues of proper application of the ne bis in idem principle. The paper specifically points to de lege ferenda legal solutions that would aim to more clearly determine the scope of labor rights that are protected by the relevant criminal norm.
Principle of legality and crime against humanity proceedings in Bosnia and Herzegovina
Authors: Ševo Olivera
Published: November 2021

The paper deals with the principle of legality from the perspective of crime against humanity proceedings in Bosnia and Herzegovina (BiH). During the armed conflict in BiH many war crimes were committed, among all others, a lot of crimes against humanity. In the time when the crimes were committed, a crime against humanity was not prescribed by the in effect criminal code. Despite that fact, criminal courts in BiH convicted numerous offenders for crimes against humanity on the basis of its prescription in international law. That led the author to the question: what was the path of crime against humanity proceedings in BiH? In the first part of the paper, the author gives an overview on the matter of jurisdiction for crime against humanity in BiH and position of principle of legality in the BiH legal system. That part also contains the insight into the main characteristics of the principle of legality's understanding in different legal traditions, but also the insight into this principle understanding in the international (criminal) law. In the second part, the author analyses Court of BiH's judgments in order to find out what was the source of law used by this court for its crime against humanity convictions. Thereafter, the author analyses Constitutional Court of BiH's decisions related to the alleged breach of BH Constitution and ECHR in relation to the principle of legality regarding crime against humanity proceedings. At the end, the paper gives the overview of ECtHR case law related to the crime against humanity proceedings in BiH - Šimšić v. BiH and Maktouf and Damjanović v. BiH cases. In the last part, the author, taking into consideration understanding the principle of legality in BiH legal tradition, presents the main conceptual problems that were raised from the crime against humanity proceedings in BiH.
Measuring the efficiency of human capital
Authors: Veselinović Nemanja , Krstić Bojan , Veselinović Martina
Published: November 2021

Increased efficiency is a necessity for any company in the knowledge-based economy, rather than an option, in the circumstances of constant change and global competition. The efficiency of using resources, especially intellectual resources, is a crucial factor in assessing the financial strength of an enterprise. Since intellectual resources are immaterial and mainly invisible, measuring and managing them is difficult. Measuring human capital efficiency provides relevant information for management, as human capital significantly affects a company's performance. The aim of the paper is to explain the importance of measuring human capital efficiency through selected conventional and contemporary indicators. This paper will show what managerial information we could get thanks to the quantification of human capital efficiency in using the specific indicators in the labour productivity analysis.

Published: November 2021

In this research, the problem of calculating the necessary static quantities of the main girder with the box crosssection of the double-beam bridge crane with two trolleys were analyzed. The aim is to determine the critical position on the girder due to the action of all loads in the vertical plane, as a function of input parameters, and to obtain expressions for calculating deflections in the vertical and horizontal planes, as well as bending moments in these planes, ie maximum (total) stress in the girder. Verification of the results was carried out in the SAP2000 software package, with proved a quite good correlation between the results obtained, for the proposed method of the calculation model of the box-girder, in the mentioned software package. The goal of this research is primarily to show how the application of the SAP2000 software package in an easy, fast and simple way can perform the dimensioning and design of this type of carrying structures, taking into account important static conditions that must be satisfied. By applying the proposed modelling method and using a certain module in the mentioned software package, the designer easily achieves the preliminary geometric values of the girder in the initial design phase, where he can completely rely on the obtained results. Also, all geometric quantities necessary for further phases in the design and calculation are obtained. Guidelines are given on how to prepare a calculation model in this software package for these types of carrying structures, as well as recommendations related to the design of these types of carrying structures made of S355 material.

Published: November 2021

The paper discusses informed consent as a component of online research ethics. It begins from the analysis of understanding, from the preconditions on which the realization depends, and from the difficulties that accompany the application of the informed consent in practice. The aim of the empirical part of the research is to determine the characteristics of the process of obtaining the informed consent in online research and to examine the factors on which they depend. The sample included 153 teachers. Data were collected with the survey-type questionnaires and with the descriptive assessment scales. For data processing, besides the frequencies and percentages, the ch 2 test and Kramer 's V correlation coefficient were performed. The results indicate that most of the respondents have had experience of giving informed consent in online surveys in which they have participated so far; that the text often contained information about the purpose and the goal of the research, apart from the tasks of the respondents in the research; that the majority of the teachers evaluate the content of the text as understandable and useful; and also that most of the characteristics depend on the environment of the school in which the teachers are employed. The results are discussed in the context of the possibility of improvement of the process of obtaining informed consent from the respondents in the online survey.

Authors: Ivanuš-Grmek Milena , Mithans Monika , Jančič-Hegediš Polona
Published: November 2021

A modern trend in quality textbooks is to stimulate different areas of student development social , cognitive, moral, and emotional, considering students' learning specifics. Textbooks are adapted to students if they consider their developmental level, experience and level of understanding ; use appropriate language; encourage reading through comprehension, and include illustrations in the text (Marentič Požarnik, 2016). The quality of learning resources that students can also use to learn independently is important. The main purpose of the Slovenian project The Quality of Slovenian Textbooks (KaUč) is to develop textbook quality indicators for practical use in validation and evaluation processes. As part of the KaUč project, an empirical research was conducted on the research sample of 505 students, with its research aim to analyse the use of textbooks and workbooks in 4th and 5th grades of primary school. Based on the performed analyses, we can determine that the use of printed textbooks prevails in all educational subjects. Textbooks are most often used for the first foreign language subject, science and technology, and for social studies.

Differential diagnosis of lymphadenopathy
Authors: Govedarović Nenad , Babić Rade
Published: November 2021

The majority of patients presenting with peripheral lymphadenopathy have easily identifiable causes that are benign or self-limited. Among primary care patients presenting with lymphadenopathy, the prevalence of malignancy has been estimated to be as low as 1.1 %. The critical challenge for the primary care physician is to identify which cases are secondary to malignancies or other serious conditions. Key risk factors for malignancy include older age, firm, fixed nodal character, duration of greater than two weeks, and supraclavicular location. Knowledge of these risk factors is critical to determining the management of unexplained lymphadenopathy. In addition, a complete exposure history, review of associated symptoms, and a thorough regional examination help determine whether lymphadenopathy is of benign or malignant origin. Unexplained lymphadenopathy without signs or symptoms of serious disease or malignancy can be observed for one month, after which specific testing or biopsy should be performed. While modern hematopathologic technologies have improved the diagnostic yields of fine-needle aspiration, excisional biopsy remains the initial diagnostic procedure of choice.
Testing of platelet function and application of rotary thromboelastometry in order to rationalize chemotherapy during myocardial revascularization and surgical treatment of heart valves

Published: November 2021

Using intraoperative salvage of blood/erythrocytes (ISB/E) in the practice, rationalized application of allogeneic blood products and hemostatic-active drugs - based on "point-of-care" (POC) monitoring findings - it is possible to improve diagnosis and evaluate of transfusion hazards and increase efficacy of therapy of patients with excessive bleedings, with reduction of perioperative morbidity and mortality in cardiac surgery. This study was performed as a prospective analysis of platelet function using "multiple platelet function analyzer" (MEA; by Multiplate) system and examination of hemostasis by rotational thromboelastometry (ROTEM) during and immediately following myocardial revascularization and surgical treatment of valves in the Institute of Cardiovascular Diseases "Dedinje" for six years period for therapy of 1021 random selected patients. The study aim was to evaluate the influence of ISB/E and hemostatic drugs - indicated based on the results of platelet count and function (Multiplate) and hemostasis monitoring (ROTEM) in compared to allogeneic transfusions - on the incidence of bleedings, treatment efficiency and overall clinical outcome. In the perioperative period, a total of 617 (60.4%) patients were treated with ISB/E reinfusion only. Other patients (404; 39.6%) received allogeneic blood components too. Total 391 of them (38.3%) were treated (together by ISB/E) with transfusion of one to three units of allogeneic red blood cells (RBCs). There were only 13 (1.3%) polytransfunded (typically 10 - 15 units) patients. The rate of cardio-surgical reinterventions due to bleeding was only 2.5%. In conclusion, the application of the ISB/E strategy represents an effective and safe (reduced immune-mediated complications and risk of disease transmission) therapeutic approach. By monitoring MEA/ROTEM and implementation the algorithm of current transfusion therapy, it is possible to reduce significantly of allogeneic blood component therapy. The use of allogeneic RBCs is justified only when the possibilities of autologous transfusion and pharmacological hemostatic therapy have been exhausted.

Published: November 2021

Coronavirus disease 2019 (COVID-19) is a severe infectious disease of the respiratory system with clinical signs of severe acute respiratory syndrome. The causative agent is coronavirus 2 (SARS-CoV-2). Common symptoms of COVID-19 pneumonia are fever, cough, shortness of breath, myalgia, expectoration of sputum and sore throat. The X-ray image of COVID-19 pneumonia has its own characteristics and changes with the evolution of the disease. At the beginning of the disease, the radiological finding in the lungs may be normal or changes may be visualized in the lungs in the form of multiple hazy vaguely delineated shadows, which occur gradually, discreetly and modestly, and in the later stage confluence into larger first irregular patch formations, then they grow into a massive irregular shadow of the intensity of the frosted glass, only to diffusely cover the whole lung. Inflammatory changes are usually bilateral, less often unilateral localization, predominantly in the middle or lower lung field, on the periphery along the chest wall and / or supraphrenic. The aim of this paper is to present an X-ray image of COVID-19 pneumonia and our experiences in the X-ray diagnosis of this disease. The material of the paper consists of selected digital radiographs of the lungs and heart and CT of the lungs with pneumonia COVID-19 in 220 patients, which are during the COVID-19 pandemic from April to July 2020. were examined in covid rendgen CC Niš. The results are presented illustratively. Conclusion: The X-ray examination methods in the diagnosis of COVID-19 pneumonia are sovereign, dominant and unrivaled, and the knowledge of the authors and collaborators and the experience gained through many years of work in the profession and co-X-ray are of crucial importance.
Nicotine: From plants to people
Authors: Olson Jana , Aryitey William , Costanzo Roberta
Published: November 2021

Nicotine is naturally present in many crops, including but not limited to tobacco, eggplant, and tomatoes. Only in the tobacco plant is nicotine present in high enough quantities (~2% of dry weight) to have pharmacological effects. People have recognized the stimulating effects of the smoke created by burning dried tobacco leaves for thousands of years, and cigarette smoking remains the most common form of nicotine uptake from tobacco. Decades of epidemiologic data show that smoking causes a number of serious diseases (including cardiovascular diseases, lung cancer, and chronic obstructive pulmonary disease [COPD]). Undoubtedly, the best way to avoid the harm from smoking is to never start. For current smokers, quitting smoking altogether is the most effective way to reduce the risk of harm and smoking-related disease. Along with other aspects such as taste and ritual, nicotine is one of the reasons people smoke. Nicotine, while addictive and not risk-free, is not the primary cause of smoking-related diseases. Indeed, experts agree that smoking-related diseases are caused primarily by chronic exposure to the harmful constituents that are produced when tobacco is burning. Nevertheless, many people still mistakenly believe that nicotine is a major cause of tobacco-related diseases. While nicotine-containing products should not be used by certain groups of people - such as minors, people with or at risk of heart disease, diabetes, epilepsy, or seizure, pregnant or breast-feeding women or women who think they may be pregnant - delivery of nicotine by less harmful means can support public health goals by encouraging smokers who would otherwise continue smoking to switch to less harmful products. It is, therefore, pivotal to address the biggest misconceptions about nicotine to empower smokers to make informed decisions. In this article, we discuss basic facts about nicotine, its effects on the human body, as well as the risks related to nicotine consumption.
Influence of synthesis parameters on mechanical properties of nanocomposite PMMA-MXene
Authors: Pešić Ivan , Petrović Miloš , Radojević Vesna
Published: November 2021

In this paper, the influence of solvents and reinforcement processing methods on the mechanical properties of nanocomposite poly-(methyl methacrylate) PMMA-Ti3C2Tx MXene was investigated. A weight fraction of reinforcement was 1% and two types of solvents were used for sample preparation: dimethylformamide (DMF) and acetone (Ac). Deionized water and DMF were used to delaminate the MXene. An additional peak at 1675 cm-1 was observed on the FTIR spectra of the obtained samples, which indicates that some amount of DMF remained in the material after drying. The results of microindentation show that samples where MXene was delaminated in deionized water and PMMA dissolved in acetone had a 74.46% higher reduced modulus of elasticity, which is supported by SEM images where better dispersion of MXenes is observed.
Assessment of sustainability of different renewable energy systems based on life cycle exergy analysis
Authors: Petrović Branislav , Gojak Milan
Published: November 2021

The sustainable development of energy systems does not only involve the use of renewable energy resources but the increase in their efficiency as well, enabling society to maximise the benefits of their consumption. The production of electrical energy from clean and renewable sources contributes to lowered fossil fuel exploitation and the reduction of its damaging effect on the environment. This is a way to reach the global target of sustainable development - striking a balance between resource consumption and the achievable natural cycle regeneration. Environmental protection is in the focus of attention. Namely, when energy system sustainability is assessed, in addition to the ecological sustainability assessment (based on life cycle analysis - LCA), attention should be paid to the decrease in energy quality in energy processes (exergy loss). This paper presents the thermodynamic approach to energy system sustainability assessment by applying life cycle exergy analysis (LCEA). The key issue is the assessment of systems which use sustainable energy sources: the wind turbine and the stand-alone photovoltaic solar system.

Monitoring of urban ambient air quality at locations of preschool and school facilities in Serbia
Authors: Matić Branislava , Dejanović Snežana , Jovanović Dragana
Published: November 2021

Exposing children to environmental pollutants during periods significant for their physiological development can lead to long-lasting health effects, dysfunction, and disease. The aim of this paper was to focus on a relatively scarce ambient AQ monitoring practice at the locations of preschol and school institutions in Serbia, within the local network of AQ monitoring stations. This was a cross-sectional study covering period 2015 to 2020. Measuring points (SO2, NO2, soot, PM10) were in front of kindergardens, primary and secondary schools in urban settlements. Results originate from the continuous public health programme conducted by the Institute of Public Health of Serbia. Only PM10 and B(a)P values at some points have exceeded annual limit values in front of chosen facilities in 2020. In sum, both the absolute number of urban ambient AQ measuring points monitored by the local network of Institutes of Public Health and those in front of the educational facilities have increased in this period: from 73/17 to 172/26. In a percentual view, these facilities are chosen more seldom within this time frame, dropping from 23.29 to 15.12% of all AQ monitoring points. As such facilities are mainly located at important city intersections, in order to assess the exposure to air pollution of vulnerable population groups (children from preschool to adolescence age), there is a need to locate measuring points near them.

Authors: Dević Aleksandar , Dević Ana , Vasiljević Mladenko , Zajić Goran
Published: November 2021

According to the definition of the World Health Organization (WHO), infertility is the inability of a sexually active, non-contracepting couple to achieve pregnancy in one year. One of the causes of sterility is inborn and acquired uterine anomalies. The best visualization of the inside of the uterus is achieved hysterscopically. Hysteroscopy is a minimally invasive surgical procedure and has the greatest significance in the diagnosis and treatment of congenital anomalies of the uterus. It is possible to eliminate and correct most of the congenital anomalies of the uterus, and it also enables the removal of other pathological changes in the cavity of the uterus. The incidence of congenital uterine anomalies in general population is 0.1-3.5%. Infertile patients have a higher incidence of these anomalies which range from 3-6%, and 5-10% in habitual abortions. The study included 200 infertile patients up to 40 years of age, with performed surgical hysteroscopy due to diagnosed changes in the uterine cavity. The patients were operated at the Department of infertility of the Obstetrics and Gynecology Clinic "Narodni Front" in Belgrade, in 2013. and 2014. The following pathological changes of the uterine cavity, were hysteroscopically removed: submucosal fibroids type 0 and type I. The aim of this paper was to evaluate the success of operative hysteroscopy in the treatment of pathological changes of the uterine cavity in infertile patients, based on the number of relapses in the first six months upon surgery. Relapses occurred in 0.5% of patients during a six-month postoperative course. Complications during hysteroscopic operations were intraoperative and postoperative. There were 1.5% of overall complications in the participants.
Use of off-label medicines in pediatric population
Authors: Radojević Sara , Krajnović Dušanka
Published: November 2021

Modern use of drugs in the treatment of diseases of children and newborns is increasingly based on off-label use of drugs. The lack of adequate formulations for the pediatric population, the lack of appropriate therapeutic parallels for the treatment of children's diseases and the small number of clinical trials involving the pediatric population have contributed to the mass use of these drugs. The use of these drugs implies extrapolation of doses and indications registered for adults to children, although it is known that the pharmacodynamics and pharmacokinetics of children and adults differ significantly. In the past two decades, many legislative and regulatory initiatives have been taken around the world to improve the use of drugs in children. However, children are still prescribed off-label and unlicensed drugs. The aim of this study was to present a review of the literature in which off-label and unlicensed use in the pediatric population was investigated. Literature was searched through the Google Scholar and Pub Med search engines and using the keywords off label drug, pediatric medicine, use in pediatrics, in the period from May to August 2019. Selected and presented in this article are studies published in the period from 1996 to 2015, which as a subject of research had the use of off-label and unlicensed drugs in the pediatric population. Medicines prescribed for children should be registered for use in the pediatric population and used in accordance with approved indications for children, whenever possible. It is necessary to take measures for more rational use of medicines in pediatrics, which include the collaboration of health workers in order to provide medicines for children that are proven to be effective, high quality and safe to use.
The molecular mechanism by which vitamin D protects against COVID-19

The SARS-CoV2 virus, which causes COVID-19, exerts its pathophysiological effect by intensively binding to the angiotensin-converting enzyme 2 receptor (ACE2) on the host cells. By blocking the ACE2 receptor, the physiological functions of the cell are inhibited, which are important for the normal function of various organs, and especially for the protection of the lungs. Therefore, the number of functionally active ACE2 receptors is extremely important for the body's resistance to COVID19. More receptors equal greater resistance of the host. An increased number of ACE2 receptors gives the body more time to mobilize an adequate immune response. Experience to date from the immediate fight against COVID19 has confirmed this rule: (A) women are generally more resistant (the ACE2 receptor gene is on the X chromosome, and women have two X chromosomes), (B) younger people are more resistant to the virus (ACE2 expression decreases with age), (C) patients with chronic diseases are more sensitive (have a reduced number of ACE2). Therefore, an increase in the number of ACE2 receptors is extremely important for the body's protective power in the fight against the SARS-CoV2 virus. Vitamin D increases the expression of the ACE2 gene, which increases the number of ACE2 receptors, which can be of significant aid in the fight against COVID-19.

Crime prevention through digitalization
Authors: Dimovski Darko
Published: November 2021

Common crime prevention measures have not yielded the expected results. It is important to examine the possibilities of using the latest achievements in crime prevention. One of the available options is digitalization. Starting from the definition of digitalization as the use of digital technologies to change the business model and provide new opportunities for generating income and value, the author emphasizes that digitalization can be used as a measure to prevent crime. In this regard, some solutions for preventing crime through digitalization are embodied in the use of digital currencies, digital identities and signatures, smart devices, and mobile applications. The author elaborates on each of these solutions, focusing on specific crime prevention measures and examples from different countries worldwide. It may help crime prevention experts perceive digitalization as a measure for reducing the volume of crime. If the benefits of digitalization are put into good use, we can expect that the volume of property-related crimes, violence-related crimes and traffic delinquency will drop in the forthcoming period. On the other hand, the implementation of these measures may give rise to the commission of Internet-related crimes, thus leading to the increase in computer crime.
ICC Rules for the use of domestic and international trade terms: INCOTERMS 2020
Authors: Fišer-Šobot Sandra
Published: November 2021

The use of trade terms in sales contracts, especially international sales contracts, is customary and very common since it contributes to the acceleration of business transactions, concurrently increasing their certainty and predictability. The ICC Rules for the use of domestic and international trade terms -INCOTERMS 2020 have been in effective use since 1 January 2020. Their goal is to enable the development of global trade in an easier, more effective and safer manner. In this paper, the author analyses the development, importance and legal nature of INCOTERMS, with special reference to its current 2020 revision and particular focus on the seller's obligation to deliver the goods and risk transfer from the seller to the buyer.
Effectiveness of procedural decisions in first-instance administrative proceedings
Authors: Vučetić Dejan
Published: November 2021

The paper analyzes the normative regulation of the procedural administrative decision institute, which was introduced into the Serbian administrative process as a novelty by the General Administrative Procedure Act (GAPA) in 2016. The paper aims to addresses three research questions: to determine the legislator's goal in regulating this insitute, to identify in which situations such a decision has to be made, and to establish how effective that type of decision is. At the beginning of the paper, the author focuses on the concept of effectiveness, including different, mutually opposed, approaches to defining that notion. The author points out the conceptual misunderstanding between efficiency and effectiveness, and their unjustified equalization. The main goal of introducing the institute of procedural administrative decision is the aspiration for greater protection of parties' procedural rights. The analysis of the text of the General Administrative Procedure Act has yielded seventeen basic types of procedural administrative decisions: a decision on rejecting the party's request, a decision not to allow alteration of the party's request, a decision on suspending the procedure, a decision on termination of the procedure, a decision on imposing a fine, decision on request, a decision on execution, a decision on securing the execution, a decision on appointing a temporary representative, a decision on denying representation to a quack lawyer for unlicenced practice of law, a decision on proposal for restitution, a decision on bearing preliminary procedure costs, a decision on exemption from procedure costs, a decision on payment of costs resulting from the absence or unjustified denial of testimony, a decision on compensation for damage to the holder, a decision on the proposal for providing evidence, and a decision on ordering an interim measure. The author concludes that the institute of procedural administrative decision can negatively affect the effectiveness of administrative proceedings due to the possibility of its unnecessary extension.
