Vitamin D and atherosclerosis
Authors: Rašević Olivera , Mulić Maida , Vuković Maja
Published: December 2021

Cardiovascular diseases rank first on the mortality list globally or 31%. The basic measure of prevention in accordance with the recommendations of the World Health Organization is a change in risk lifestyle in terms of diet, physical activity, tobacco and alcohol consumption. Vitamin D was previously recognized as a regulator of calcium and phosphorus ratio, bone remodeling or the main controller of skeletal pathophysiology. However, vitamin D enjoys great interest in clinical and epidemiological research in terms of its possible impact on reducing the risk of cardiovascular diseases. Among other things, vitamin D deficiency is associated with an increased risk of endothelial dysfunction. Although the deficiency has been identified as a risk marker for cardiovascular diseases, the mechanism of action of vitamin D on the path from endothelial dysfunction to cardiovascular diseases has not been fully revealed. The findings in this segment of activity of vitamin D would be significant in terms of reducing morbidity and mortality from cardiovascular diseases.

Published: December 2021

Poultry meat production represents one of the most intensive production in poultry fattening. Broiler's production lasts on average 42 days, which enables quicker income of the employed resources. With the ban of dietary antibiotics usage in poultry meat production, new natural feed additives had to been engaged. This research aimed to investigate the effects of medicinal plants addition to broiler rations on the economic results of the production. Our results have reviled significantly (p<0.05) positive effects. Chickens on medicinal plants (T1) addition have recoded much higher total benefit at the end of production (698.1 €) than chickens on control (T2) treatment (335.6 €). Following the same tendency, the benefit per chicken was also higher in medicinal plant treatment (0.15:0.07 €) and profitability (8.01:3.59%). Upon the gained results, it can be assumed that usage of dietary, medicinal plants expresses a beneficial effect on the monitored economic parameters compared to broilers fed with commercial compound mixtures.
Supply and demand in engineering and management
Authors: Yanev Bojidar
Published: December 2021

All successful infrastructure products and processes exemplify the collaboration of engineering and economics in space and time. In their respective domains, the two specialized professions optimize supply and demand (S / D) of energy and money. If their priorities diverge, structural and economic failures result. The various stages of a bridge lifecycle and the transitions between them are examined as vulnerable nodes and links where diverging constraints of supply and demand must be reconciled. Robustness, resilience and sustainability are considered as properties which, if sufficiently defined, can model realistically the cost-effective performance of the infrastructure under varying conditions over extended lifecycles.

The remedial effects of garlic in various metabolic complications have been attributed to a variety of organosulfur compounds such as allicin, diallyl sulfides, alliin and allyl trisulfides. The present study was designed to prepare an aqueous extract of garlic with stable allicin and its biological evaluation on tissue-specific nutrigenomic effects in the prevention of High-fat diet (HFD)-induced weight gain and related complications in Sprague-Dawley (SD) rats. Aqueous Allicin-rich garlic extract (ARGE) was prepared and characterized for stability of allicin using HPLC. For biological evaluation, animals were fed with either normal pellet diet (NPD), HFD, HFD along with ARGE (1ml/kg p.o.) and ARGE per se (1ml/kg p.o.) for 16 weeks. Chronic administration of ARGE prevented HFD-induced weight gain, adipose tissue hypertrophy, insulin resistance and improved overall glucose homeostasis. Transcriptional analysis of different tissues highlighted that ARGE promoted browning, improved glucose metabolism and appetite regulation. Overall, this study presents ARGE as a potential nutraceutical for the prevention of obesity and related comorbidities.

Published: December 2021

In this paper, we will demonstrate in what way and to what extent the university teaching of the Italian language as an elective and compulsory-elective academic course has changed in the online context imposed in the conditions of the Covid-19 pandemic. The transition from classroom teaching to online teaching (pure e-learning, then blended learning) in synchronous and asynchronous form significantly influenced a number of factors important for the acquisition of the Italian language and introduction to the elements of Italian civilization and culture. The aim of the research was to examine the efficacy of organized (a)synchronous online teaching, to determine to what extent this second way of teaching affects students' academic motivation to learn Italian as an elective second foreign language, and to establish preconditions for achieving various aspects of motivation: experience with online teaching, achievement, technical difficulties, and attitudes about online teaching. The research was conducted among students of different departments at the Faculty of Philosophy, University of Novi Sad. The study involved 136 students of Italian (85% of respondents), aged 19 to 33 years (AC = 20.55) who had online classes. Using latent profile analysis, four profiles of academic motivation were registered: highly motivated (8% of respondents), moderately motivated (49%), low autonomously motivated (17%) and highly unmotivated (26%). The paper presents affiliations with the profiles in relation to: 1.) experience in online teaching before the pandemic, 2.) academic achievement, 3.) difficulties with the Internet connection during online teaching, and 4.) attitudes about online teaching. The results of the research indicate that the largest number of students prefer live teaching to online, but also that previous experience in online teaching has a significant impact on maintaining optimal or achieving a high level of motivation.

Postmodern culture as a social logic of neoliberal capitalism
Authors: Urošević Milan
Published: December 2021

The aim of this paper is to explore the relation between changes in the economic sphere and the emergence of postmodern culture during the twentieth century. After examining Jameson's and Harvey's (neo)Marxist attempts at explaining the emergence of postmodern culture, the paper will focus on Foucault's contribution to the analysis of neoliberalism. Using Foucault's analysis of neoliberalism as a "governmental regime" that creates systems of power relations to govern subjects, the paper further explores the postmodern culture as a cultural dimension of this regime. In conclusion, postmodern culture can be viewed as a cultural dimension of neoliberalism because it contributes to the creation of subjects that correspond to the needs of the regime. Therefore, postmodern culture will be called "the social logic of neoliberalism".
Industrial heritage and creative initiatives as catalysts of event tourism
Authors: Jevtović Aleksandra
Published: December 2021

The concept of sustainable urban development requires re-purposing of buildings and areas in service of local communities. Industrial complexes which are no longer used for their original purpose are often left to degrade, simply because their demolition requires large investments. In such circumstances, creative sector initiatives were proved to be of multiple importance. They do not require too much of financial investment and do provide authentic solutions for the given problem. Innovation in that domain significantly contributes to the tourism industry, in particular to some forms of selective tourism and to outbound markets whose demands are increasingly difficult to be satisfied by mass tourism products. Among examples from practice, the case of "Ciglana" in Karaburma (Brick factory) in Belgrade stands distinguished, as a place where the festival "Dev9t" dedicated to creativity has been organized. This area contains the memory of various layers and stages of Belgrade's industrialization and it is not under institutional protection. In this paper, the process of its adaptive reuse was discussed, as well as new meanings assigned to it by the festival activities.

Fatigue as a threat in civil aviation
Authors: Isaković Velimir , Đurđević Dragan
Published: December 2021

Fatigue as a term does not represent a disease, but a state of reduced mental and/or physical potentials and requires an interdisciplinary approach to detecting and managing risks in mutually related and conditioned work processes. Knowing the principle of fatigue allows us to discover, understand, predict and reduce the possibility of escalation of problems in a timely manner. Today, fatigue is recognized in civil aviation as the direct cause of more than 20% of incidents. Security and safety management measures are mainly aimed at reducing threats from a technical or procedural aspect while ignoring the fact that inadequate management of the Human Factor causes 80% of injuries, loss of life and material damage.

Authors: Cvetkovski Tatjana , Cvetkovska-Tomanović Violeta
Published: December 2021

The paper deals with the role of digital communication in the tourism sector. The aim is to determine whether the use of digital communications is only an available opportunity or a necessity imposed by a new generation of travelers (the so-called Millennials and Generation Z) and new circumstances coused by the coronavirus pandemic. Communication and today digital communication are an important aspect of our lives. People use the Internet to do business, socialize, inform, share their impressions, to shop. The way people travel is changing as well. They look for information about touristic destination and products online, assess impressions of those who have already visited destinations or happenings and stayed in specific accommodation. Then they book transportation and accommodation on-line via websites and platforms. The tourism sector is information intensive and this is why digital communication is important for this sector. Some quickly got used to the new reality and began to use all the opportunities provided by the new digital technology, while some found it harder to accept. Until the beginning of 2020. tourism become one of the fastest-growing economic sectors in the world, and steady growth would certainly continue but corona virus pandemic happened and everything has stopped. The corona virus pandemic has set new requirements for the tourism sector and is already dictating new ways of doing business. Through various statistical and other data used in the paper, we will see that at the beginning the usage of digital technology and digital communication in the tourism sector was something that existed as a possibility but today this is a necessity of modern business.
Legacy in the Republic of Serbia: Concept and types
Authors: Račić Anđelka
Published: December 2021

The family is the basic cell of every society; in it the life of an individual rises, develops and disappears. Family relations are the basis of every social and state system. As a result, all state systems have been trying to keep family relations in peace for centuries. The death of a family member is one of the many factors that can disrupt family harmony, especially under the additional influence of property rights. Centuries ago, the issue of the testator's property was regulated by customary law, and then by legislation. The paper deals with the institute of bequest, as one of the forms of inheritance, with special reference to the types of bequests in the Republic of Serbia. For centuries, bequest has been the institutional of transferring the property and legal relations of the testator to the heirs. The will as we know it today in its form has its basis in Roman law, which had a great influence on the first European civil codes, the Civil Code and the Austrian Civil Code. These codes are still in use today, and their special significance is that they are a panda to all later adopted civil codes, ie to all later established civil legal bases. The Austrian Civil Code had a dominant influence on the settings of the regulation of civil law in the Republic of Serbia. Today, there are nine types of bequests. Each of them follows the life situations, circumstances and circumstances in which it arises.

Published: December 2021

In most modern countries, the social democratic and liberal approaches prevail on the place of the public sector in state management and socioeconomic development, which significantly reduces the role of the public sector in production activities, so the public sector today largely encompasses social activities, i.e. socially upgrading production activities. Regardless of the ideological approach, the public sector is undeniably the most important factor of the state, on whose efficiency and effectiveness the degree of economic and legal environment as a basic prerequisite for the development of society and the development of social activities depends.
Aggression on Kosovo between media construction and reality
Authors: Stanković-Pejnović Vesna
Published: December 2021

Aggression against Kosovo is an example of how the NATO and the 'international community' have (mis)used Serbia and Kosovo in a classic modern exercise of identity construction by disciplining the Balkan 'other'. The discourse of security is not a neutral academic terrain, but a continuous struggle for political power, access to resources, and the authority to articulate new definitions and priorities of security. Modern reasons for war were absent because the conflict in Kosovo centered around the pursuit of moral aims (rather than traditional politics) by other means. The vocabulary employed related more to the tradition of a just war (a notion that preceded the era of modern wars), which was firmly grounded in denationalization and aimed to replace politics with the imperative of universal principles and virtue. The aim of the paper is to show that the Kosovo model of aggression, behind the discourses of moral goals, traditionally political, has aimed to implement the New World Order of imperialist powers under the auspices of the 'international community' and to establish full control over natural resources.

Raising environmental awareness through art projects
Authors: Marković Sanja , Petrović Jelena
Published: December 2021

The paper analyzes the importance of actively raising awareness about the significance of ecology and the preservation of our environment through various art forms. The role they play in the process is an important one, both in terms of educating the younger, and raising awareness among the older generations about environmental issues. Art strives for the preservation of culture and cultural heritage, and represents a permanent record of a certain age, a way of life, the social and political circumstances, human opinions, and socially relevant topics. Ranging from architecture, as the most frequently used type of art, via literature and film, to music which reaches the widest of audiences, it can convey any message to the greatest number of people, and each art form can give its own contribution to environmental issues. Socially engaged art is a frequent occurrence. Throughout history, art has been used as a call to rebellion, resistance, and change. Environmental topics have been increasingly more present in art over the past few decades, but are still not present enough. Great potential for the awakening of mankind in terms of the environmental challenges we are facing lies precisely in various art forms. Everyone has their own preference when it comes to art, which is why no art form should be neglected; instead, they should all be developed equally so as to encourage as many people as possible, spanning all generations, to consider the importance of environmental issues.

Authors: Jwan Sabah , Salah Farhan , Shuokr Qarani
Published: December 2021

The issue of rationalizing water consumption and preserving it for future generations is one of the most important indicators of sustainable development referred to in the Agenda 21. This study aims to assess the sustainability of water resources for the city of Erbil in terms of quantity and quality. In this study, the amount of water available in the existing water sources was evaluated and compared with the volume of water demand. The reliability of water sources, especially groundwater, in the selected area was evaluated and confirmed. The study also focused on the management of groundwater by the concerned authorities and the identification of factors that help to develop the sustainability of these sources. The problems facing the management of groundwater and the proposed solutions to solve these problems were also identified. Due to the rapid growth of the populations and lack of both water demand and water supply system, Erbil City required a fundamental evaluation of water supply systems and good planning for future. However, in this study, the assessment was conducted based on the existing data and the accurate archived documents as well. As a result, the study concluded that there have been a lot of problems that should be taken into consideration in order to provide good managing of the groundwater system. It was also observed that there was slightly higher depletion in groundwater table due to poor supplying. This study can be used as a fundamental reference for future investigations especially for those areas having the same problems in sustainable management of the subsurface basins.

Published: December 2021

Planning, construction and maintenance of forest roads is extremely important for successful firefighting in a certain area. This study focuses on the current technical infrastructure in the state forests of Serbia. The average openness of forests in Serbia at the end of 2019 was 20.14 m/ha, while 21.89 m/ha was occupied by public roads. In the period from 2011 to 2019, the average openness of state forests with public roads in Serbia decreased by 3.12 m/ha, or by 1.67 m/ha. The openness of forests by forest roads is the largest and optimal in the Vojvodina region (131.5 m/ha) and significantly lower and insufficient in Belgrade regions (0.35 m/ha), Sumadija and Western Serbia (2.8 m/ha), and Southern and Eastern Serbia (1.8 m/ha). Compared to 2011, the openness of forests in 2019 increased in the Vojvodina region and decreased in other regions in Serbia. Forest roads that have asphalt, concrete or cobblestone lanes are the least represented, about 0.27%. The largest representation of forest roads with a base (stone or gravel hard bottom layer) is about 82.7%.

Authors: Pavić Katarina , Milutinović Dragana
Published: December 2021

Introduction: Burnout syndrome is a condition caused by chronic stress at the workplace. Resilience is the ability to cope with the negative situations in life. Purpose: To evaluate the extent of burnout syndrome in nursing teachers at medical high schools and the effect of the level of resilience on burnout syndrome. Material and methods: This cross-sectional study interviewed 101 nursing teachers at four medical schools. Teacher Burnout Scale, The Connor-Davidson Resilience Scale and socio-demographic questionnaire have been used as instruments of the study. Results: The majority of nursing teachers had moderate symptom of burnout syndrome. The average result on the burnout scale was 56.1. Statistical analyzes showed that there is no statistically significant difference in the manifestation of burnout syndrome in teachers in relation to demographic characteristics (sex, marital status, years of work experience and subjects at medical school). By analysing the results of the two scales, it has been established that there is no statistically significant association between the burnout intensity and the degree of resilience in nursing teachers. Conclusion: The results of the study showed moderate level of burnout in nursing teachers. This may help as an encouragement to develop a strategy for preventing emergence of the burnout syndrome. The results will be useful for further research of burnout syndrome in nursing teachers.

Introduction: Intrahospital infections have a great impact on the mortality rate and morbidity of hospitalized patients. The importance of nosocomial infections makes it important for nurses to know and implement preventive measures during provision of nursing care. Objective: To analyze knowledge and attitudes of nurses about nosocomial infections. Material and methods: The research was conducted on a population of nurses and technicians employed at the General Hospital in Subotica. The sample included 44 participants. The research instrument was a questionnaire designed for the purposes of the research. Data were analyzed using descriptive statistics and hi-square test. Results: The definition of nosocomial infections was known to 68% of respondents, but only 50% of respondents knew that the hands of healthcare professionals were the most common way of spreading nosocomial infections. Basic preventive measures against nosocomial infections were familiar to 82% of respondents, and 95% of the respondents thought that nurses have important role in the control and prevention of nosocomial infections. Significantly more respondents who have more than 20 years of work experience thought that nurses do not have contribution in prevention and control of nosocomial infections (p=0.011). Conclusion: Most participants were familiar with the definition of nosocomial infections and basic preventive measures. It is necessary to improve the knowledge about the ways of spreading and the risks for the occurrence of nosocomial infections.

Published: December 2021

Introduction: Acute myocardial infarction (AIM) is ischemic myocardial necrosis and is associated with a number of adverse outcomes that complicate patient health care. Assessment of patient status, risk factors, and adverse outcomes has a significant impact on patient care planning after AIM. The GRACE (Global Registry of Acute Coronary Events) score is of great importance in risk stratification in these patients. Objective: To determine the importance of determining the GRACE score in order to set priorities in the planning of patient care after acute myocardial infarction. Method: A retrospective study examined 50 patients, both sexes, aged 28 to 75 years, with a diagnosis of acute myocardial infarction, undergoing percutaneous coronary intervention (PKI), who were treated at the Zvezdara Clinical Hospital in Belgrade during the research period, from January to March 2020. Data were taken from the medical records of these patients. During the study, AIM type, comorbidities, CVD risk factors, GRACE score and frequency of complex nursing interventions in patients with low, moderate, and high-risk of adverse cardiac events were monitored. Results: Out of a total of 50 examinees with AIM treated with PKI, 74% had STEMI and 26% NSTEMI. 84% of patients had positive family history, 64% hypertension, 2% diabetes, 48% obesity, 52% were smokers and 6% of them were using alcohol. The values of the GRACE score were increased as follows: in four patients more than 140, while in one of them a moderate value was recorded, and in one low value of the GRACE score. In the course of six months, three patients, who had high GRACE scores on hospitalization, had a lethal outcome. Complex nursing interventions in the intensive care unit are more common in patients who have high GRACE score values after AIM. Conclusion: The GRACE score can be used as an important guideline in planning the health care of patients after an acute myocardial infarction.

A large number of interesting Co (II) complexes with macrocyclicligands have been synthesized and the recognition of its complexes as important bioactive compounds in vitro and in vivo has aroused growing interest in these agents as potential drugs for therapeutic use in various diseases. Numerous available information on their bioinorganic properties and mode of action in several biological systems, combined with the new possibilities imposed by the development of medical chemistry, opens space for the development of a new generation of highly active drugs with minimized side effects which could add significantly to the current clinical research and practice. In this paper we attempt to present some properties of the earlier isolated the first Co(II)tpmc complex for which crystal structure confirmed chair conformation of macrocycle. Complex with formula (Co2(Cl)2tpmc)(BF4)2 (tpmc = N,N`,N``,N```tetrakis(2-pyridylmethyl)-1,4,8,11 - tetraazacyclotetradecane), was studied on thermal behaviour and biological activity. TG-DTA analysis indicates that complex decomposition in a single step in the range of 365 -435 °C. Investigated cytotoxic activity against two human cancer cell lines: HeLa (human cervix adenocarcinoma) and K562 (human myelogenous leukaemia). Complex was also preliminary assayed in vitro toward bacteria, fungi and mould together with the starting material for the synthesis (ligands, simple salts and solvents) as test substances. Investigated complex showed a moderate activity against strains of bacteria and were inactive against the tested fungi and mould. Minimal inhibitory concentration suppressing the visible growth of bacteria was determined. Biological investigations show the complex has significant cytotoxic potential.
Closure of Serbian elementary school in Shkodra in 1934
Authors: Velojić Dalibor
Published: December 2021

After signing the treaties of Tirana, Albania became the representative of Italy for the Balkans. The activities directed toward the Kingdom of Yugoslavia were determined by Yugoslav and Italian relations, which were rather tense at that period. General negation of Yugoslav presence in Albania was evident in the area of education, and as a result, Serbian schools were closed in territories predominantly inhabited with Serbian people, under the pretext of carrying out reforms. The example of the Serbian elementary school in Shkodra best reflects the effects of Albanian education policy regarding ethnic minorities. Archives of Yugoslavia, department of the Ministry of Education, contains the file (pages of documents) related to this school. This paper is based on the mentioned file, as well as available general literature on Yugoslav Albanian relations.
The first records of Prince Vladimir in sources
Authors: Đekić Đorđe
Published: December 2021

The paper attempts to answer the question of the first records of Prince Vladimir in historical sources. Up to now it has been considered that he was first mentioned in the work "A Synopsis of Byzantine History" by John Skylitzes. However, Henri Grégoire and Raoul De Keyser indicate that the prince was mentioned in "The Song of Roland" ("La Chanson de Roland") as rei flurit, i.e., as the Blessed King. This epic originates from the spring of 1085 in Salerno, which was under the Norman rule at the time. This author agrees and supports the thesis by identifying a great number of concepts which refer to the Balkans (geographically, ethnically). It is believed that the Normans obtained information about the Balkans and Prince Vladimir while they held Dyrrhachium from 1081 to 1085.

The culture of reading, and interests of students in the school reading, changes from generation to generation. We have opted for gymnasium students of the third and fourth grade because we regard them as active readers with developed reading tastes and habits. Students who have home libraries and are surrounded by books, and whose parents have a higher level of education, read more on average than those who have no books at home and live in a less developed cultural and economic environment. Information about student literary interests is set as a methodological requirement and growing scientific attention is paid to it. The paper analyses the research findings on reading interests of students of the third and fourth grade of the general secondary education in schools in the City of East Sarajevo. All data should indicate: the level of reading culture that has been achieved; whether students regularly read the required reading and works outside the compulsory programme; which topics they are interested in; which works they prefer to read; and whether there are differences in interests depending on the gender of students, their academic achievements, and family and socioeconomic opportunities. The method of systematic empirical non-experimental research was applied.
Formative assessment of achievements in mathematics and selection of tasks
Authors: Šćepanović Rada , Milinković Jasmina
Published: December 2021

The evaluation of mathematical knowledge is based on multiple sources of information. In modern teaching practice, a special place has a formative evaluation of mathematical achievements of students as an integral part of teaching that supports learning and provides useful information to teachers and students. The paper is dedicated to the analysis of innovative evaluation techniques in mathematics teaching that reflect the changed paradigm of mathematics education. The aim of this paper is to explore the features and implications of authentic evaluation techniques and, accordingly, to make the choice of tasks as evaluation instruments. Using the method of theoretical analysis of research results of authentic methods for assessing mathematical knowledge, skills and attitudes, we determine the criteria for selecting tasks for evaluating students' mathematical achievements (focus on in-depth and extended application of existing knowledge in different contexts, multiple solutions, research possibilities). The discourse is then directed towards considering the originality of the task evaluation criteria. In the final considerations, we point out that the selection of mathematical tasks creates an opportunity to apply a wide range of authentic techniques in evaluating students 'mathematical achievements, and broader and deeper plans the further course of teaching in students' cognitive and motivational development. We point out that by choosing mathematical tasks, it creates an opportunity to apply a wide range of authentic techniques in evaluating students' mathematical achievements, and broader and deeper plans the further course of teaching in the cognitive and motivational development of students.
The use of modern technologies in the life and work of teachers before and during Covid virus
Authors: Jevtić Radoje
Published: December 2021

Modern technologies are present in almost every part of human`s life and work. One of the most important spheres of human's life is an education. The penetration of modern technologies in this life`s sphere is huge, especially in last several years. These facts purport that teachers, professors and other educators must introduce and teach their pupils to use these technologies on appropriate way. This role is very important and complex. Teachers must find appropriate way to realize balance between "digital" skills needed for pupils to accept the school material, use benefits of "digital" environment and continue to use and develop the imagination and other activities used by older "no digital" generations. So, teachers must continuously learn and become acquainted with modern technologies and their benefits and use them in life and work. The modern technologies are different, but in elementary schools, secondary schools and houses of students, the most frequently used are mobile phones, laptops, tablets, Internet, social networks etc. The main goal of this paper is to present the results of use of noted modern technologies in life and work of teachers. Researches presented in this paper were realized by author of this paper as longitudinal researches and included teachers in different educational institutions, such as elementary schools, secondary schools in Niš and in pupil's homes.
Comparative analysis of the approach to music education in the methods of Edgar Willems and Maurice Martenot
Authors: Tanasković Marija
Published: December 2021

The paper presents a comparative analysis of the Willems method and the Martenot method, bearing in mind their attitude towards music education. The richness of each method, especially when it comes to gaining practical experiences in music education, can be a very important basis for improving general music education today, as well as learning in the field of music. These methods are characterized by specific characteristics and approaches related to aspects of rhythm, melody, harmony and body movement, but also the integration of contents of other arts. Therefore, the aim of the paper is to present the specifics and advantages of both methods, based on the analysis of the way in which each of the methods is conceived - starting points, understandings of music education, theoretical foundations of both methods, phases of work and used materials, and the role and importance of teachers.
El empleo del vocablo phantasma en las fuentes literarias latinas: de los primeros registros a los autores cristianos tardorromanos
Authors: Serrano Madroñal Raúl
Published: December 2021

Ghosts are the cultural product of a series of beliefs that stem from the existence of a dissociated numen that inhabits the human body. It is this separation that makes possible to conceive the autonomous presence of the spiritual entity. This ancestral type of story has been reproduced since the dawn of humanity, although this work seeks to elucidate what the connotations of use of a Greek term are, that passes into Latin and that undergoes an evolution through the filter of Christianity. Through a study of a historical-philological nature with a comparative perspective, this article aims to show the differences in use, paying special attention to the patristic texts of Tertullian and the allegorical and Christian poetry of Prudentius.

Los fantasmas son el producto cultural de una serie de creencias que parten de la existencia de un numen disociado que habita dentro del cuerpo humano. Es esta separación la que permite concebir la presencia autónoma de la entidad espiritual. Este tipo ancestral de relato viene reproduciéndose desde los albores de la humanidad, si bien en este trabajo se persigue dilucidar cuáles son las connotaciones de empleo de un término griego que pasa al latín y que experimenta una evolución a través del filtro del cristianismo. Mediante un estudio de carácter histórico-filológico y con una perspectiva comparativa, el presente artículo se propone manifestar las diferencias de uso, prestando especial atención a los textos patrísticos de Tertuliano y a la poesía alegórica y cristiana de Prudencio.
