Authors: Dweiri Mohammad Ahmad , Shatat Abdallah Saleh
Published: January 2021

The purpose of this paper is to examine the effects of knowledge management and advanced technology on innovative capability in order to improve the organization performance. A survey of 200 SMEs in the service industry was conducted. Partial least squares structural equation modelling (PLS_SEM) was used to test the mediation role of the service innovation on the relationships between both knowledge management and advance technology and the organizational performance. The results showed there were links between knowledge management and organizational performance. Nevertheless, it was discovered that service innovation mediated the relationship between the knowledge management and cost and financial performance, and between advance technology and cost and financial performance. The paper shows a way forward of how to measures the organizational performance in such a way that they are led from the development of innovation capability generated through knowledge management and the advance technology in the service industry.
Similar but different: investigating temporal constructions in sign language
Authors: Aristodemo Valentina , Hauser Charlotte
Published: January 2021

This paper presents a study of French Sign Language (LSF) temporal constructions. While we know from spoken language research that temporal constructions can be expressed through a variety of syntactic strategies such as subordination, juxtaposition, and coordination, finding their equivalent in sign languages is often a challenge due to the absence of overt complementizers and other function words such as coordinators. This study explores temporal constructions in LSF and frames them within a broad typological perspective. We show that LSF temporal clauses are very different from those of Italian Sign language (LIS) studied by Aristodemo (2017). Specifically, LSF temporal constructions are composed of two coordinated clauses and the temporal marker is integrated into the second conjunct. LIS temporal clauses, on the other hand, are composed of a main and a subordinated clause. This finding shows that the typological categories found in spoken language are also relevant for sign language studies.

Authors: León-Duarte Jaime Alfonso , De La Re-Iñiguez Blanca Melissa
Published: January 2021

The purpose of this research is to develop a methodology for improving a wiring harness production process that allows for tracing the products that are processed in a specific area - in this case in a foam injection operation - by implementing a bar-coded electronic monitoring system. The steps involved in this methodology are as follows: a prior analysis of the area; development of a traceability program; implementation of the system and, finally, evaluation of the results. Thanks to the information obtained through the new traceability system, the main defects in the area were identified and specific actions were taken to minimize their recurrence, achieving a 23% reduction of defects after one month of trials.
El nuevo modelo de convivencia urbana: los enclaves habitacionales auto-segregados en Managua
Authors: Gutiérrez Lanza Danna
Published: January 2021

La investigación urbana en Latinoamérica ha identificado la existencia de nuevos modelos del espacio urbano en las ciudades de la región. Este modelo representa cambios en el patrón de segregación espacial, que en términos socio-habitacionales (o urbano-habitacional) implica que, aunque los grupos se encuentran en mayor proximidad física, están separados por muros o tecnologías de seguridad.

En Managua el modelo de crecimiento urbano ha seguido una lógica de dispersión de baja densidad que se expande hacia las áreas suburbanas. El patrón muestra una expansión a lo largo de los ejes viales radiales convertidos en ejes importantes de inversión para desarrollos habitacionales con un carácter muy marcado: las viviendas de la “clase alta” (Rodgers, 2006). El fenómeno de la segregación espacial toma mayor fuerza a partir de la década de 1990 y hoy una serie de proyectos habitacionales que se caracterizan por su carácter segregativo acentúan el proceso de urbanización “desordenado, discontinuo y desigual” (López, 2016, p.28).

Seguridad, control, gestión, son los aspectos más importantes sobre los cuales se perciben diferencias de estos espacios habitacionales en relación a la experiencia en la ciudad abierta, y por tanto se han convertido – tanto en su expresión físico-espacial, como en la social – en objeto de una evaluación diferencial, que deviene en una diferenciación de la experiencia urbana-habitacional.
Proporciones generales en las iglesias patrimoniales de Granada, Nicaragua
Authors: Cruz Ramírez Luis Carlos , Cruz Contreras Evelin
Published: January 2021

El objetivo de este artículo es presentar un análisis sobre la proporción en los edificios monumentales religiosos del departamento de Granada, Nicaragua. Los objetos de estudios fueron los edificios religiosos catalogados como patrimonio inmueble, localizados en este departamento. Se consideró como guía para esta investigación los edificios registrados e Catálogos de Bienes Culturales de Granada. Con base en dos catálogos consultados, la muestra obtenida fue de 11 edificios. Dos análisis probabilísticos fueron realizados, considerando las propiedades de la muestra y los objetivos de la investigación: análisis de regresión y análisis de conglomerados. Se encontró que los edificios catalogados de género religioso, localizados en el departamento de Granada, en un solo conjunto no responden a un solo patrón de proporción. En promedio se aproximan a la relación 1: 2.42. Sin embargo, los coeficientes de correlación y determinación son valores medianamente representativos. Los resultados obtenidos son de utilidad para ampliar los conocimientos en ciencia básica en el ámbito del conocimiento de las proporciones mismas, de los edificios locales de este género. Fortuitamente, podrá ser de utilidad en futuros proyectos de proyección de nuevos edificios que deseen considerar este aspecto formal, adoptando el criterio de diseño tipológico.
Headache, eyestrain, and musculoskeletal symptoms in relation to smartphone and tablet use in healthy adolescents
Authors: Falkenberg Helle K. , Johansen Tina R , Thorud Hanne-Mari Schiøtz
Published: January 2021

Neck pain and headache are leading causes of years lived with disability globally, and the prevalence is gradually increasing from school age to early adulthood. These symptoms have been linked to the use of digital devices. However, there is little knowledge related to this topic in adolescents, who spend increasingly more time using digital media. The aim of the study was to investigate eyestrain, headache, and musculoskeletal symptoms in relation to the use of tablets and smartphones in healthy adolescents with normal vision. Fifty healthy adolescents aged 11 – 13 years (mean = 12.1 (SD = 0.53)) with normal vision and development participated. A vision examination was performed by an authorised optometrist and an interview questionnaire measuring eyestrain, headache, and musculoskeletal symptoms in relation to screen use was filled out. In addition, screen time, ergonomics, participation in sports, and outdoor time were obtained. Forty-nine (98%) of the 50 children used a smartphone and 17 (34%) used a tablet. Overall, 12% to 41% experienced symptoms of headache, neck pain, tiredness and/or tired eyes while using smartphones and tablets. Nine (18%) experienced at least one symptom often or always while using their device. Musculoskeletal pain and headache were significantly associated with vision and eyestrain. Tablet use was associated with increased symptom scores compared to smartphone use. Increased screen time and shorter viewing distance were associated with eyestrain, headache, and neck pain. Children with neck- shoulder- and back pain were significantly (2.1 hours) less physically active than children without these symptoms. Most adolescents with good health and vision had no symptoms while using smartphones and tablets. However, a significant proportion still experienced symptoms of headache, neck pain, tiredness and tired eyes, and these symptoms were associated. Symptoms increased with screen time, shorter viewing distance and reduced participation in sports. This suggests that even healthy children with good vision may develop vision symptoms and musculoskeletal pain. Awareness should be raised among parents, teachers, eye care- and health care personnel, of the importance of good visual ergonomics and physical activity to promote health in adolescents.
Differential Involvement of Working Memory Capacity and Fluid Intelligence in Verbal Associative Learning as a Possible Function of Strategy Use
Authors: Martinez David , O’Rourke Polly
Published: January 2021

The paired-associate paradigm has a long history of use in basic and applied research on human memory and learning. A number of studies have shown that people differ in the strategies they use to encode information in paired-associate tasks and, importantly, that strategies differ in their effectiveness. What is not so well documented is how different strategies may affect the cognitive processes assessed by paired-associate tasks. In this study, we submitted archival data to distributional and latent class analyses to infer strategy use and classify participants as elaborators or nonelaborators. We then used regression analyses within subgroups to identify differences in dependence on fluid intelligence and working memory capacity. To the extent that our classification was accurate, the results suggest that paired-associate learning is more reliant on fluid intelligence when elaborative rehearsal is used and more reliant on working memory capacity when nonelaborative strategies are used. To offer further evidence of the validity of our approach, we also investigated correlations between strategy use and fluid intelligence and working memory capacity. In accord with prior research, we found that cognitive abilities were positively correlated with what we infer to be differences in strategy use. That the cognitive processes assessed by verbal paired-associate tasks may vary as a function of strategy use should be a concern for all researchers and practitioners who use such tasks.
Pupil Dilation as an Index of Verbal Fluency
Authors: Haj Mohamad El , Lenoble Quentin , Allain Philippe
Published: January 2021

Verbal fluency tasks are widely used as a neuropsychological test of language production. We assessed pupil dilation during a verbal fluency task and during a control task. On the verbal fluency task, we asked 45 healthy participants (mean age = 23.55 years) to generate as many words as possible beginning with the letter “P,” whereas on the control task we asked them to count aloud. In both tasks we recorded pupil dilation with eye-tracking glasses. Results demonstrated that, compared with counting, verbal fluency resulted in a larger pupil dilation. The larger pupil dilation observed during verbal fluency compared with counting can be attributed to the cognitive load of verbal fluency, which involves both linguistic processing and executive function. By highlighting how verbal fluency can increase pupil dilation, our findings pave the way for the physiological assessment of verbal processing in healthy and pathological populations.
Elementary Students’ Music Compositions with Notation-Based Software and Handwritten Notation Assisted by Classroom Instruments
Authors: Kang Sangmi , Yoo Hyesoo
Published: January 2021

The purpose of this study was to investigate the impact of notation-based software on music composition by comparing student compositions, preferences, and perceived advantages and disadvantages of composing music with and without the aid of notation-based software. The study included 37 upper-grade elementary students who composed eight measures of melody with notation-based software (MuseScore2) and handwritten notation assisted by classroom instruments (glockenspiel) during 12-week music composition lessons. Student preferences and their comments for each compositional mode were also collected. Afterward, the compositions were judged by five music teachers using Amabile’s consensual assessment technique with criteria of creativity, aesthetic appeal, and craftsmanship. Results indicated that notation-based software for music composition scored higher in creativity, while compositions on the hand-written notation assisted by glockenspiels scored higher in craftsmanship. Of the participants, 76% preferred composing music with the aid of notation-based software because of the playback function and perceived ease. Compositions using notation-based software demonstrated higher scores in creativity than handwritten compositions. However, handwritten compositions scored higher in craftsmanship. Comments by students after composition suggested that handwritten approaches allowed them to use composition strategies learned during prior teaching sessions, although they showed a lower preference for it.
The Characteristics and Career Influences of Male Elementary General Music Teachers
Authors: Bulgren Christopher W.
Published: January 2021

The purpose of this study was to describe the characteristics of male elementary general music teachers and investigate career factors from social cognitive career theory. Items included influential others (teachers, friends, and family), performance accomplishments (career-related activities in coursework, student teaching, general music positions, and professional development), and social persuasions (social factors related to teacher preparation programs, colleagues, and school setting). Responses to an online questionnaire from 140 male elementary general music teachers were analyzed with three types of statistical analyses: frequencies, independent samples t-tests, and simple linear regression. Results include demographic data and findings related to the interaction of prior experiences, career preparation, and in-service experiences. Other results indicate a wide variety of primary instruments, career trajectories, and original career intentions. Respondents identified those who influenced them, their success in coursework, and their social interactions. Suggestions for the profession include a required elementary general methods course for all preservice music teachers and a portion of student teaching in an elementary general music setting. Respondents developed teacher identities that allowed them to navigate issues related to elementary general music such as career expectations and working in a feminized profession.
“It’s More Than Playing Music”: Exploring Band in a Predominantly Latinx Community
Authors: Gerrard Crystal Lynn
Published: January 2021

Drawing from Irizarry and Raible’s (2011) barrio-based epistemologies and ontologies as a theoretical framework, I examined a middle school band program with a high enrollment of Latinx students to explore the compatibility of the traditional concert band model with this population of youth. Additionally, I assessed how asset-based principles functioned in this environment. Data collection in this case study included semistructured interviews, field observations, and material culture. A total of 19 participants engaged in interviews comprising band directors, band students, band parents, teachers, and administrators. Findings indicated that some aspects of this traditional band program corresponded with asset-based practices, specifically the band directors’ cultivation of community among students and stakeholders, and their cognizance of the sociopolitical context of which the students were a part. Importantly, band directors and other school personnel were keenly aware of stressors students and families experienced, which included cultural barriers and issues pertaining to undocumented citizenship status. Band, however, did not resonate entirely with all participants, as some students expressed a desire for creative music-making opportunities that more closely aligned with their personal interests. Implications from this study provide insights for improving music education practices in Latinx communities, such as the importance of reducing language barriers, supporting students’ cultural identities, and developing an awareness of sociopolitical issues that significantly impact the daily lives and well-being of students and their families.

Published: January 2021

This study aims to identify key sectors in countries showing any class change in level of income and to examine whether there is any relationship between sectors and income classes. Another aim of the study is to identify emerging and disappearing sectors in key sectors during periods when countries’ income levels change. In this context, four basic income classes published by the World Bank are examined for 43 countries but class change was identified only in 12 countries between 2000-2014. A statistical difference was determined between the sectors in the classes at Low and Low Middle levels and Upper Middle and High) classes. Among these countries discussed in the 15-year period with 56 sectors examined, some sectors showed feature of being common key sectors, some tendency to be a key sector in recent years and some sectors have lost their key feature before or after the direct income class changes.
“Singing” in a primary school of the interwar period in the context of nationwide educational-ideological conceptions – source analysis
Authors: Pietraszewska Danuta
Published: January 2021

One of the first objectives of the Polish state, restored after the period of partitions, was to develop a new, standardized and nationwide system of public education. During the interwar period, school curricula objectives were affected by changing political powers and reflected the government’s pursuits and ideas. In the first years after regaining independence, the focus was placed on the idea of national education and the development of good morals, alumni’s independence, as well as the necessity of learning through hands-on experience. The May Coup changed rules of the political system and, as a result, led to the formulation of an educational ideal emphasizing the concept of a state and the cult of the marshal Piłsudski’s figure. The article analyses assumptions of the “Singing” program so as to find an answer to the question of how the state’s political ideas were implemented on the grounds of general music education. A pedagogical-historical perspective, providing the context for musical issues, was adopted. An in-depth analysis of sources, such as legal acts, school curricula and pedagogical journals from the period of 1918-1939, showed that the leading role in delivering pedagogical-ideological objectives belonged to the teaching of singing as a form of education, and to a school song with patriotic, religious or ludic topics, which formed the rudiments of education and music pedagogy. Research findings indicate a relation between a political idea and content-related, methodological matters regarding education and music pedagogy.
Group classes and the development of individualities of students from the specializations of choreography and musical
Authors: Łuczyńska Agnieszka
Published: January 2021

The article signals the problem an academic teacher must face while teaching a group class in artistic fields of study. The development of artistic individuality and awareness is a long and complex process, heavily influenced by the relation between a teacher’s and student’s personality, as well as the use of relevant to the situation, motivational tools. Is such a process likely to be observed while giving classes to a group of students? What factors does it depend on? What does the process of a student’s self-discovery rely on in this situation? The author presents her reflections based on the experience gained while working with choreography and musical students at the Academy of Music in Łódź.
An Experiential Education Approach to Teaching the Mind-Body Problem
Authors: Manafu Alexandru ,   Philosophy Documentation Center
Published: January 2021

This article shows how the mind-body problem can be taught effectively via an experiential learning activity involving a couple of classroom props: a brick and a jar of ground coffee. By experiencing the physical properties of the brick (shape, weight, length, width) and contrasting them with the olfactory experience of coffee (seemingly dimensionless, weightless, etc.), students are introduced in a vivid way to the well-known difficulty of explaining the mental in physical terms. A brief overview of experiential learning theory and its connection to philosophy is also provided.
The Emergence of Onto-Gnoseology among Russian Intuitivists as Criticism of Neo-Kantianism
Authors: Bonadyseva P. R.
Published: January 2021

At the beginning of the twentieth century in the Russian-speaking philosophical space philosophical projects emerged which brought ontology and gnoseology closer together. One can observe this process, for example, in the philosophical doctrines of the Russian intuitivists Nikolay Lossky and Semyon Frank. I demonstrate that the emergence of these doctrines and the development of their onto-gnoseological categorial apparatus were mainly connected with the criticism of the Neo-Kantian theory of cognition and the possibility of transcendent knowledge as such. The main sources of my study are The Intuitive Basis of Knowledge and The World as an Organic Whole by N. O. Lossky and The Object of Knowledge and The Unknowable by S. L. Frank. My investigation makes it possible to treat Lossky’s categorial framework as the representation of a system of levels of the universe each of which is characterised by two aspects: the ontological, i.e. it is part of the unity of the world, and the gnoseological, i.e. it has an independent cognitive significance. Frank considers categories to be an organic part of the ontological proof of intuitivism. A common trend in the construction of categorial schemes by Lossky and Frank is their striving to combine gnoseological and ontological descriptions of categories. The key difference is the way an onto-gnoseological system as a whole is justified. In revealing the contradictions in Lossky’s conception, I proceed from the critical remarks of S. A. Askoldov (Alexeyev), pointing out that these contradictions stem from an absolutisation of intuition in cognition, the renunciation of the idea of gnoseological transcendence, incompleteness of the theory of immanence and discordance between onto-gnoseological categories. Askoldov’s critical comments clarify the substantive features of Lossky’s theory and the essence of the transformations carried out in Frank’s absolute ideal-realism.

Quality standardization: A factor of sustainable competitiveness of companies in Serbia
Authors: Miletić Vuk , Ćurčić Nikola , Simonović Zoran
Published: January 2021

The analysis of the possibilities of creating the sustainable competitiveness of an enterprise from the point of view of the functional uniformity of economic and ecological sustainability, as well as the production of products in compliance with the international standards for business operations, is the subject matter of the research conducted in this paper. The achievement of a higher level of competitiveness is a strategic goal of every enterprise, while the competitiveness of a product implies an appropriate standardization of quality. The starting assumption is that in order for enterprises to become competitive not only on the domestic market, but on the international market as well, it is necessary that they should standardize their business operations by improving the quality system. The goal is to gain an insight into how much significance domestic enterprises give to the standardization of quality, apart from the other needed factors, how interested they are in investing in the implementation of the ISO 9000:2000 standards, which are primarily oriented towards the satisfaction of client requirements, thus improving their own business operations. In this research study, the hypothetical-deductive methods, analytical-deductive and comparative methods, historical and statistical-descriptive methods, as well as the comparative statistical methods (ch2 Test, ANOVA), are used.

The fast growth of counterfeiting medicines in the last two decades has created one of the biggest problems facing the pharmaceutical industry on the global level, resulting in loss of income, product withdrawal, loss of brand value, etc. But this is not only the problem of the intellectual property rights of the pharmaceutical industry, it is also the problem of the healthcare regulatory authorities, whose most significant concern is the risk to the public health. Pharmaceutical manufacturers, together with the wholesalers and retailers, have an essential role in the fight against counterfeit medicines by the implementation of different anti-counterfeit technologies for securing the supply-chain of medicines. The protection of drug packaging has a specific role in the drug development process, as well as in the fight against counterfeit medicine. The authenticity of the medicine and the forensic elements for protection on the packaging may be confirmed using different technologies. Tracking and tracing of pharmaceutical products in the supply chain, keeping electronic records for all stages of the distribution, and verification of the authenticity of a medicinal product is a key element and an effective solution for timely detection of counterfeit medicines and protection of intellectual property rights.
Species of the genus Alternaria pathogens of vegetable and spice plants from the family Apiaceae
Authors: Trkulja Vojislav , Perviz Mehira , Mitrović Petar , Vojvodić Mira , Bulajić Aleksandra
Published: January 2021

Species of the genus Alternaria are among the most important plant pathogens that occur worldwide on many host plants, as well as plants of the Apiaceae family, including important vegetables such as carrots, parsley, celery, parsnips and fennel, and popular herbs such as anise, cumin, dill, coriander and others. These plants are attacked by different species of phytopathogenic fungi of the genus Alternaria, and this paper offers current review of nine different species. However, there is still insufficient information on both these species and the nu-merous interactions between them and their host plants and environmental factors. This information are necessary as the basis for adequate disease control measures and thus enabling successful and profitable cultivation of these high valued crops. Therefore, we present pathogen profiles of A. dauci, A. radicina, A. carotiincultae, A. petroselini, A. selini, A. smyrnii, A. alternata, A. longipes and A. burnsii as pathogens of Apiaceae plants, as well as their full current names and synonyms, taxonomic position, distribution and symptoms these pathogens cause to their host plants, as well as their biology and mode of transmission and spread, with special emphasis on control measures.
The weeds in root vegetables and possibilities of their control
Authors: Konstantinović Bojan , Popov Milena , Samardžić Nataša , Stojanović Tijana
Published: January 2021

The limited number of permitted herbicides for the application in the crops of carrots, red beet, celery and parsnip, as well as the diversity of weeds occurring in these crops, make the successful weed control difficult, due to which the appli-cation of preventive measures is necessary to reduce the number of weeds in the fields during the vegetation as much as possible. The preventive measures include the use of mulch, as well as the application of the crop rotation. Currently, for the application in carrots several herbicides based on active substances pendimethalin, clethodim and propaquizafop have been registered:, for the application in red beets one herbicide based on metamitrone has been registered, while in case of parsnip and celery there are no registered herbicides in our country. Considering the grow-ing problem of the weed resistance to the herbicide, it is significant to recognize the necessity for the application of antiresistance strategy which encompasses: the rotation of herbicides with different modes of action, the minimum herbicides application, as well as the crop rotation.
Contemporary changes in the ethnic structure of the population in the Autonomous Province of Kosovo and Metohija
Authors: Milosavljević Saša , Medojević Jovo
Published: January 2021

Twenty years (1999 - 2019) after the end of the conflict in the Autonomous Province of Kosovo and Metohija, it can be stated that nowhere in Europe is there such ethnic segregation of the population as is the case with the AP of Kosovo and Metohija. Following the withdrawal of pumped security forces from the entire territory of Kosovo and Metohija and the entry of the United Nations peacekeeping force into the Serbian Autonomous Province, Kosovo Albanians carried out their persecution from Kosovo through terrorist attacks on Serbs and other non-Albanian populations (Montenegrins, Gorans, Roma, Ashkali) carried out their persecution from Kosovo and Metohija and fundamentally changed the ethnic structure of the Province. An insight into the majority of 223.081 exiles and displaced persons from Kosovo and Metohija indicates an exodus against the Serbs. The number of displaced Roma, Ashkali and Egyptians is estimated at about 100.000. The mass persecution of the Serb and other non-Albanian populations has resulted in tremendous changes in the ethnic structure of the Province, which today, with 93% of the total population, is dominated by Albanians, while other ethnic communities have a participation of 7%.

Published: January 2021

This paper deals with the general technical, spatial, and temporal characteristics of satellite telecommunications systems. Particular attention was paid to the peculiarities of the territory of the Republic of Serbia in terms of implementation and use of modern satellite telecommunication infrastructure. The overview shows how and on which way to use various satellite telecommunication systems to configure and exploit next-generation networks, especially modern communications such as 5G technology and IoT. Their work cannot be imagined without the high speeds and high frequencies that allow us to transmit a wealth of information - from short messages/news to HD video on a mobile phone. We need either a base station network or in the case of the high seas or areas where the base station system is difficult to imagine, we need satellite communication. The paper presents data that give a numerical and graphical overview of geostationary satellites visible from the territory of the city of Belgrade, depending on the orbital position and the associated angle of azimuth and elevation, which would also be valid for the leading territory of Serbia.
Functional transformation of West Morava Valley District settlements
Authors: Penjišević Ivana , Dragojlović Jovan
Published: January 2021

The existing territorial layout and the current demographic situation in the settlements of West Morava Valley District during the late 20th century and at the beginning of the 21st century are the result of the synchronized action of the process of industrialization, deagrarization and urbanization. They conditioned the selective transformation of urban and rural space, which led to the concentration of the population in urban and suburban settlements and the depopulation of the rural part of the West Morava Valley District. Within the studied region, the hierarchy of municipal centers, subcenters and communities of settlements was observed. Based on important theoretical and methodological assumptions and indicators, the paper analyzes the functional transformation of the settlements of West Morava Valley in the period between 1971-2011. It was determined by certain quantitative methods that the changes went in the direction of reducing the share of purely agrarian settlements and increasing the share of industrial and service settlements.
Predicting the type of physical activity from tri-axial smartphone accelerometer data
Authors: Pavlović Katarina
Published: January 2021

Development of various statistical learning methods and their implementation in mobile device software enables moment-by-moment study of human social interactions, behavioral patterns, sleep, as well as their physical mobility and gross motor activity. Recently, through the use of supervised Machine Learning, Human Activity Recognition (HAR) has found numerous applications in biomedical engineering especially in the field of digital phenotyping. Having this in mind, in this research in order to be able to quantify the human movement activity in situ, using data from portable digital devices, we have developed code which uses Random Forest Classifier to predict the type of physical activity from tri-axial smartphone accelerometer data. The code has been written using Python programming language and Anaconda distribution of data-science packages. Raw accelerometer data was collected by using the Beiwe research platform, which is developed by the Onnela Lab at the Harvard T.H. Chan School of Public Health. Tuning has been performed by defining a grid of hyperparameter ranges, using Scikit-Learn's Randomized Search CV method, randomly sampling from the grid and performing K-Fold CV with each combination of tested values. Obtained results will enable development of more robust models for predicting the type of physical activity with more subjects, usage of different hardware, various test situations, and different environments.

Correlation of physical activity with stress, depression and anxiety in female students
Authors: Pilipović-Spasojević Olivera , Ponorac Nenad , Spremo Mira
Published: January 2021

Background/Aim: The period of beginning of studies is a stressful period of life in which students are expected to develop skills and abilities with which they will be able to take on the most important roles in all areas of social activity. Physical activity (PA) triggers and remodels mental health. The aim of the study was to determine the correlation between PA and stress, anxiety and depression in female students. Methods: Epidemiological observational study was performed and included a representative sample of 408 healthy female students aged 19 to 22 years. Questionnaires were used and anthropometric measurement of weight and body mass index (BMI) calculation was performed. Used questionnaires were: a socio-demographic questionnaire, standardised tests: DASS-21 test (short version) for mental health assessment and International Physical Activity Questionnaire-IPAQ test (long version). Results: Mean age of female students was 20.5 ± 0.72 years, average height 168.65 ± 6.01 cm, body weight 63.09 ± 9.9 kg, and BMI 22.1 ± 3.2. A significant negative correlation was found between high PA and anxiety (r =-0.160, p = 0.001), PA and depression (r =-0.118, p = 0.01), while the category of stress had a low correlation with PA. Conclusion: This research shows that a high level of PA has no effect on stress but has an effect on reducing anxiety and depression.

Traumatic abdominal wall hernias (TAWHs) are uncommon health conditions that involve a disruption of the muscular layers after a blunt abdominal injury. A consensus in the management of TAWHs has not been established, owing to the scarce number of reported cases. These hernias can occur under a broad array of clinical presentations, from stable and asymptomatic patients to emergency situations with associated intra-abdominal injuries. The aetiology of TAWHs is diverse and can occur at all ages, however it is more likely to be reported in children and elderly patients. Clinical findings must be correlated with a CT scan, which will confirm the diagnosis. Early diagnosis and treatment were found to be associated with a lower risk of complications and mesh use during the surgical repair is an efficient mean of reducing recurrences after the surgical repair. However, the timing of repair and surgical solution still depends on the patient's condition.
The first modern pharmacy in Banja Luka: The Brammer family, three generations of pharmacists
Authors: Marković-Peković Vanda
Published: January 2021

Pharmacy activity in Bosnia and Herzegovina was regulated in 1879 by an Order of the Provincial Government, at the beginning of the Austro-Hungarian occupation. The pharmacy owner had to have a doctorate in chemistry or a master's degree in pharmacy obtained at an Austro-Hungarian faculty. The Law on Pharmacies was adopted in 1907. The first modern pharmacy in Banja Luka was opened by Moritz Brammer in 1879. The pharmacy was inherited by his son Robert, who had sons, Ernest, Hans and Alfred, pharmacists. Ernest inherited father's pharmacy, where he worked as of 1921. Hans, also a writer and a publicist, worked in this pharmacy (1921-1930). He emigrated to Israel in 1949. Before World War II, Alfred owned a pharmacy and a drugstore in Zagreb. The Brammer family, a well-known one in Banja Luka, contributed greatly to the cultural and social development of the city in the time in which they lived.

Background/Aim: Total hip replacement is considered as one of the most successful treatment methods in orthopaedic surgery of the 20th century, since it significantly improves the quality of life of the individuals with coxarthrosis. Protocols and the organisation of the postoperative rehabilitation differ significantly around the world. The aim of this study was to investigate the effect of hydrokinesitherapy on the rehabilitation outcome in patients after total hip replacement under in-patient conditions. Methods: This prospective clinical trial included a total of 100 patients of both genders , average age 59.11 ± 8.85 years, which were admitted to the in-patient post-operative rehabilitation after total hip replacement. Patients were randomised in two groups: group A (n = 50) that was subjected to rehabilitation program with hy-drokinesiherapy and group B (n = 50) that was subjected to rehabilitation program only. The parameters registered were: the range of movement in the operated hip, the circumference of the femoral musculature and the Western Ontario and McMas-ter Universities Osteoarthritis Indeks (WOMAC index) at admittance and discharge from in-patient rehabilitation. Results: The average values of hip flexion with extended knee, extension and external hip rotation were significantly better in group A (p < 0.05). The values of the circumference of the femoral musculature and WOMAC index in patients from group A were significantly better on discharge compared to the admission. Also, this group had a statistically significantly better values of the circumference of the femoral musculature and value of WOMAC index at discharge compared to patients from group B (p < 0.05). Conclusion: Hydrokinesitherapy as a part of the protocol for postoperative rehabilitation in patients after total hip replacement leads to a faster improvement of the functional status of the operated hip and patient's quality of life.

The analysis of the quality of surface water of Danube in the Republic of Serbia for 2018
Authors: Durlević Uroš
Published: January 2021

Today, the quality of water in the world is changing significantly due to the increasing human impact on the environment. The paper presents an analysis of the surface water quality of the Danube river at five hydrological stations in Serbia for 2018. Using the relevant method - the water quality index, in this case, the Serbian water quality index (SWQI) ten physico-chemical and microbiological parameters (oxygen saturation, Five-Day Biochemical Oxygen Demand or BOD5, ammonium ion concentration, pH value, water) were analyzed Total Nitrogen or WTN, Total Suspended Solids or TSS, orthophosphate concentration, electrical conductivity, temperature and fecal coliform bacteria presence in water). The values obtained are classified in 5 classes depending on the water quality. The lowest (good) water quality was recorded on the Zemun - Smederevo river course, while in Bezdan, Novi Sad and Radujevac, the average annual water quality is very good.
A Rare Case of Coil Migration into the Duodenum after Embolization of a Right Colic Artery Pseudoaneurysm
Authors: Choi Jeongmin , Kim Young Moon
Published: January 2021

Transcatheter arterial embolization is a safe and effective treatment for visceral artery aneurysms; nevertheless, some complications can occur. Coil migration to other organs after embolization is extremely rare, and only 16 cases have been reported previously. We report a rare case of coil migration to the duodenal lumen after embolization of a right colic artery pseudoaneurysm. To the best of our knowledge, this is the first case of coil migration after a right colic artery embolization. The patient exhibited no symptoms and was treated conservatively without any intervention. Some previous reports have demonstrated spontaneous coil passage and successful conservative management. Our case supports conservative treatment as the primary treatment for asymptomatic patients. Clinicians should assess the risks and benefits of coil removal in asymptomatic patients before performing any intervention.
El mito de los grandes ‘hombres exportadores’ como estrategia de dominación de las élites locales en un territorio rural
Authors: Ramírez Melgarejo Antonio José
Published: January 2021

La Vega Alta del río Segura en la Región de Murcia es una comarca rural que, durante el último siglo, se ha ido conformando en un importante enclave productivo agrícola. Actualmente está plenamente inserto en las grandes cadenas globales de comercialización de productos en fresco para toda Europa, especializado en uva apirena y frutas de hueso. Durante su particular proceso socio-histórico, las relaciones sociales que se producen entre las diferentes clases sociales que conviven en el territorio se han ido construyendo, modificando y adaptando a los grandes cambios también sociales, sin que cambien en lo sustancial. Las élites locales constituidas como coaliciones locales de crecimiento han detentado (y detentan) poder suficiente para tratar de controlar el devenir del modelo socio-productivo local. El objetivo ha sido (y es) conservar y tratar de fortalecer su posición de poder. Para ello han sido capaces de desplegar a lo largo del tiempo estrategias de dominación adaptadas a los grandes cambios sociales y estructurales. Como ejemplo analítico presentaré tres casos prototípicos de exportadores, pertenecientes a tres generaciones diferentes, que desplegaron formas de dominación similares pero adaptadas a su tiempo.
