COVID-19 vaccine attitude: A review on turkey
Authors:   Child Health and Diseases Department, Istanbul Education Research Hospital, Istanbul, Turkey, et al. Öngel
Published: September 2022

The study investigates the anti-vaccine attitude and the attitude towards COVID-19 in Turkey. Within the scope of the study, an online questionnaire was applied to 564 volunteers with a convenience sampling technique between 21/05/2021 and 01/06/2021. Analysis was performed with descriptive and inferential statistical analysis techniques and a multiple probit model. As a result of the estimation, it has been determined that negative claims about the vaccine have an increasing effect on the probability of being vaccinated or undecided, according to the probability of being vaccinated. It has been seen that it has a reducing effect on their thoughts about making the vaccine compulsory. Opposition to the COVID-19 vaccine has become global, and people's behaviors endanger their health, public health, and global health due to the following unscientific theories that need to be further examined scientifically. In particular, awareness-raising activities for individuals, more efficient use of social media channels for communication, support of countries' academic studies on the subject, and transparent sharing of scientific data with the public will change the attitude toward vaccines. When we look at the literature, it has been seen that social media channels are neglected in the vaccination attitude. However, it was found to be an essential factor in line with the findings obtained from the study. For this reason, it is thought that it will contribute to future studies.
Optimized Informed Consent for Psychotherapy: Protocol for a Randomized Controlled Trial
Authors: Gerke Leonie , Ladwig Sönke , Pauls Franz , Trachsel Manuel , Härter Martin , Nestoriuc Yvonne
Published: September 2022

Background

Informed consent is a legal and ethical prerequisite for psychotherapy. However, in clinical practice, consistent strategies to obtain informed consent are scarce. Inconsistencies exist regarding the overall validity of informed consent for psychotherapy as well as the disclosure of potential mechanisms and negative effects, the latter posing a moral dilemma between patient autonomy and nonmaleficence.

Objective

This protocol describes a randomized controlled web-based trial aiming to investigate the efficacy of a one-session optimized informed consent consultation.

Methods

The optimized informed consent consultation was developed to provide information on the setting, efficacy, mechanisms, and negative effects via expectation management and shared decision-making techniques. A total of 122 participants with an indication for psychotherapy will be recruited. Participants will take part in a baseline assessment, including a structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5) disorders. Eligible participants will be randomly assigned either to a control group receiving an information brochure about psychotherapy as treatment as usual (n=61) or to an intervention group receiving treatment as usual and the optimized informed consent consultation (n=61). Potential treatment effects will be measured after the treatment via interview and patient self-report and at 2 weeks and 3 months follow-up via web-based questionnaires. Treatment expectation is the primary outcome. Secondary outcomes include the capacity to consent, decisional conflict, autonomous treatment motivation, adherence intention, and side-effect expectations.

Results

This trial received a positive ethics vote by the local ethics committee of the Center for Psychosocial Medicine, University-Medical Center Hamburg-Eppendorf, Hamburg, Germany on April 1, 2021, and was prospectively registered on June 17, 2021. The first participant was enrolled in the study on August 5, 2021. We expect to complete data collection in December 2022. After data analysis within the first quarter of 2023, the results will be submitted for publication in peer-reviewed journals in summer 2023.

Conclusions

If effective, the optimized informed consent consultation might not only constitute an innovative clinical tool to meet the ethical and legal obligations of informed consent but also strengthen the contributing factors of psychotherapy outcome, while minimizing nocebo effects and fostering shared decision-making.

Patients' choice preferences for specialist outpatient online consultations: A discrete choice experiment (Preprint)
Authors: Wu Mengqiu , Ma Chengyu , Li Yuhan
Published: September 2022

BACKGROUND

Internet hospitals are multiplying with solid support from the Chinese government. In internet hospitals, specialist outpatient online consultations (SOOC) are the primary services. However, the acceptance and utilization rates of this service are still low. Thus, the study of patients’ choice preferences for SOOC is needed.

OBJECTIVE

To analyze the choice preference of patients’ SOOC via a discrete choice experiment, understand the influence of each factor and promote the development of internet hospitals.

METHODS

Via a discrete selection experiment, a total of 162 patients from two general hospitals and three specialized hospitals in Beijing were selected for the questionnaire survey. The choice preferences were analyzed by conditional logit regression.

RESULTS

From high to low, patients’ willingness to pay (WTP) for the attributes of SOOC is as follows: doctors’ recommendation rate (βhighly recommend=0.999), the convenience of applying SOOC services (βconvenient=0.760), the increasing ratio of medical insurance payment for online services compared to offline (βincreased by 10%=0.545), and the disease’s severity (βsevere=-3.024). The results of the subgroup analysis showed differences in patient choice preference by age, whether the patients had chronic diseases, income, and medical insurance types.

CONCLUSIONS

Both price and nonprice attributes influence the choice preference of SOOC for patients. Among them, patients are more inclined to choose SOOC when doctors highly recommend it, when it is convenient to apply, when medical insurance increases by 10%, and when disease severity is mild. The current findings show the government and medical institutions formulate auxiliary policies and welfare strategies by clarifying core attributes and adjusting the levels of different attributes to improve patients’ acceptance with SOOC. The utility of SOOC and further development of internet hospitals are radically promoted.

Published: September 2022

Cefixime is a third-generation cephalosporin antibiotic with poor solubility and permeability. The aim was to compared between Dry Grinding (DG) and Liquid-Assisted Grinding (LAG) methods to formed cocrystal of cefixime with nicotinamide. Cocrystal was prepared in 1:1 molar ratio and was characterizated by differential scanning calorimetry (DSC), fourier transform infra-red (FTIR), scanning electron microscopy (SEM), x-ray diffraction (XRD) methods. Cocrystal properties such as solubility, dissolution rate, and permeation rate were evaluated. The solubility test results obtained: 0.420 ± 0.016 (cefixime); 0.675 ± 0.016 (cocrystal 1:1 LAG); and 0.632 ± 0.016 (cocrystal 1:1 DG). The dissolution test results obtained: 186.55 ± 4.18 (cefixime); 232.83 ± 4.07 (cocrystal 1:1 LAG); and 228.82 ± 10.07 (cocrystal 1:1 DG). The permeability test results obtained: 153.58 ± 31.94 (cefixime); 306.22 ± 77.81 (cocrystal 1:1 LAG); and 211.44 ± 22.90 (cocrystal 1:1 DG). Cefixime can be formed into cocrystal with nicotinamide by DG and LAG methods according to the results of characterization using DSC, FTIR, SEM, and XRD accompanied by the increasing solubility, dissolution, and permeability. Cocrystal 1:1 LAG showed better result compared to cocrystal 1:1 DG.

Authors: Hartanti Yesiska Kristina , Nugroho Agung Endro , Tjandrawinata Raymond Rubianto
Published: September 2022

Diabetic Peripheral Neuropathy (DPN) significantly affects the quality of life with no definitive therapy currently. Given the pathologic basis for DPN treatment, it's critical to promote neuron regeneration while also restricting nerve degeneration. Schwann cells that play pivotal roles against peripheral regeneration manifest cell proliferation and survival inhibition in diabetic patients consecutively decreased peripheral regeneration capacity. DLBS1033N, a protein hydrolysate obtained from Lumbricus rubellus, has been confirmed to promote Schwann cell line RSC96 growth and survival by induction Nerve Growth Factor (NGF) expression via phosphatidylinositol-3‑kinase (PI3K) pathway. This pathway has an important contribution against Schwann cell proliferation and migration. Herein, the contribution of DLBS1033N to peripheral regeneration on high-glucose (50mM)-induced rat Schwann cell line RSC96 injury, a well-known DPN in vitro cell model. RSC96 were treated with high glucose (50mM) with or without DLBS1033N 25, 50, and 100μg/mL for 24, 48, and 72 h. MTS assay kit were used to evaluate cell viability. DLBS1033N significantly improved cell proliferation in 48 h incubation time with a dose-dependent manner (p < 0.05). Furthermore, DLBS1033N 100μg/ml significantly promoted cell migration by 16% in 48 H incubation (p < 0.05) determined by scratch assay, as the beneficial action to accomplish peripheral regeneration. In conclusion, DLBS1033N enhanced peripheral regeneration which could be used as an effective and promising DPN treatment.

Authors: Putri Vania Santika
Published: September 2022

A simple validated UV/Vis spectrophotometric method to analyze quercetin released from the nanoemulsion matrix has been developed to study the drug release profile of quercetin loaded-nanoemulsion. Quercetin analysis was carried out at a maximum wavelength of 254 nm. The method showed linearity with a correlation coefficient (r) value of 0.9998 in the range of 4 - 12 μg/mL. The results also demonstrated that the procedure is accurate and precise, with recovery (%) in the range of 99.65 - 100.1312 % and RSD (%) as ≤ 2%. The limit of detection (LOD) and limit of quantitation (LOQ) values were found to be 4.0535 μg/mL and 13.5118 μg/mL, respectively. The developed method was found to be valid to analyze quercetin released in nanoemulsion preparations.
Critical Criminology: Past, Present, and Future
Authors: Chao Yu-Hsuan
Published: September 2022

Crime problems have drawn more and more attention in recent years, with criminological theories widely developed. Critical criminology is perhaps the most controversial and ambitious among those theories because it abandons the state's definition of crime, demonstrates the injustice of society, and tries to address crime problems (or social harm) more comprehensively. Meanwhile, its radical position attracts criticisms, such as ignoring real victimisation.

The essay aims to explore the past, present, and future of critical criminology and explain why society requires such a critical voice. First, it introduces the origin and development of critical criminology. Then, through two current examples - the war on terror and COVID-19, it illustrates the critical perspective's value of comprehensiveness and independence, especially compared to mainstream criminology. Lastly, it indicates the challenges and how critical criminology could develop in the future to pursue its goal - real equality and justice.

Authors: Ranđelović Branislav , Nikolić Saša , Milovanović Aleksandra , Ilić Ivana
Published: September 2022

In this paper we apply multistep recurrence relations, as one of very simple and useful mathematical models. It is an efficient tool for solving many problems in mathematics, science, and technics. We also use generating functions, as a connection between real number sequences and real functions, and as a very smooth and efficient connection between the discrete mathematics and (continual) mathematical analysis. We present an application of multistep homogenous linear recurrence relations for modelling some processes in the control theory. Further on, we use the ordinary generating function aiming to find appropriate formulae for calculating members of an appropriate recurrence sequence. Finally, we show the application of this novel mathematical approach on one real example in the control theory.
COVID-19 PANDEMIC AND NIGERIA’S INTERNATIONAL LIQUIDITY: IMPACT ANALYSIS
Authors: Babalola Abdurrauf
Published: September 2022

Covid-19 pandemic woes have caught across almost every international activity in the world today, which makes many economies to be in a cross-road whether the COVID-19 pandemic is the cause of these woes or not. In this regard, this study investigated the effect of the COVID-19 pandemic on international liquidity in Nigeria. COVID-19 pandemic was proxied by COVID-19 new cases and new deaths of the pandemic in Nigeria and a dummy which represented the period of the pandemic, and as such, stood in as the explanatory variables in the study, while international liquidity was put as the dependent variable. Daily data sets were sourced from National Centre for Disease Control in Nigeria and the Central Bank of Nigeria statistical bulletin between February and October 2020, employing Auto-Regressive Distributed Lag (ARDL) technique. Findings of the study revealed that, in the short run, the COVID-19 pandemic period had a significant impact on Nigeria's international liquidity. However, the COVID-19 new cases and new deaths could not have any significant impact on the international liquidity. Moreover, none of the COVID-19 pandemic variables could have any long-run impact on the international liquidity in Nigeria. The study, therefore, suggests that Nigerians should know that the depletion of its foreign reserve is not due to policy deficiency but to the COVID-19 pandemic. Also, the government should try to improve quality exports that will be demanded by foreign countries irrespective of any pandemic.
DIACHRONIC ECOLOGICAL DISCOURSE ANALYSIS OF IMDb
Authors: Kolahdouz Mohammadi Mandana
Published: September 2022

Media is a useful tool to convey various types of messages. Within the past years, broadcasting media has covered a wide range of different communication methods such as television, radio, newspapers, and magazines. The article's central hypothesis is that movies, TV, and video games quotes, as the subcategory of broadcasting, convey messages about environmental issues. It seems that ecological discourse analysis can be useful, as it focuses on texts about the environment. In a diachronic approach, the present article aims to explore the environmental issues in movies, TV, and video games quotes; in this regard, we analyzed ecological discourse and solutions proposed by IMDb quotes. The data was collected from the IMDb database using Keyword in Context (KWIC) over 1990-2020. The findings indicated that KWICs such as global warming (38%) and endangered species (19.18%) had the highest frequencies. On the other hand, only 0.67% of the raw numbers of quotes belonged to environmental issues, which indicated that IMDb quotes implicitly conveyed the message regarding ecological matters. Furthermore, the studied IMDb mostly explained the consequences and provided solutions to environmental issues. Therefore, the frequency of informing people about environmental negligence was much lower than expected.
SPECIAL ORGANIZATIONS
Authors: Golubović Milena
Published: September 2022

The paper explores the normative framework on special organizations in the Republic of Serbia. Being an integral part of the state administration, they have features which are common to all organizations as well as some specific and highly distinctive features. Special organizations are primarily instituted to perform professional and related administrative activities whose nature requires a higher degree of independence when compared to the independence required in the work of administrative authorities within the organizational structure of ministries. In this paper, the author discusses the concept, characteristics, significance and specific position of special organizations, as well as their activities and organizational structure.

ROBUSTNESS ANALYSIS OF THE DATA-SELECTIVE VOLTERRA NLMS ALGORITHM
Authors: Sharafi Javad , Maarefparvar Abbas
Published: September 2022

Recently, the data-selective adaptive Volterra filters have been proposed;however, up to now, there are not any theoretical analyses on its behavior rather than numerical simulations. Therefore, in this paper, we analyze the robustness (in the sense of l_2-stability) of the data-selective Volterra normalized least-mean-square (DSVNLMS) algorithm. First, we study the local robustness of this algorithm at any iteration, then we propose a global bound for the error/discrepancy in the coefficient vector. Also, we demonstrate that the DS-VNLMS algorithm improves the parameter estimation for the majority of the iterations that an update is implemented. Moreover, we also prove that if the noise bound is known, then we can set the DS-VNLMS so that it never degrades the estimate. The simulation results corroborate the validity of the executed analysis and demonstrate that the DS-VNLMS algorithm is robust against noise, no matter how its parameters are adopted.

ON THE NUMBER OF CYCLES OF GRAPHS AND VC-DIMENSION
Authors: Mofidi Alireza
Published: September 2022

The number of the cycles in a graph is an important well-known parameter in graph theory and there are a lot of investigations carried out in the literature for finding suitable bounds for it. In this paper, we delve into studying this parameter and the cycle structure of graphs through the lens of the cycle hypergraphs and VC-dimension and find some new bounds for it, where the cycle hypergraph of a graph is a hypergraph with the edges of the graph as its vertices and the edge sets of the cycles as its hyperedges respectively. Note that VC-dimension is an important notion in extremal combinatorics, graph theory, statistics and machine learning. We investigate cycle hypergraph from the perspective of VC-theory, specially the celebrated Sauer-Shelah lemma, in order to give our upper and lower bounds for the number of the cycles in terms of the (dual) VC-dimension of the cycle hypergraph and nullity of graph. We compute VC-dimension and the mentioned bounds in some graph classes and also show that in certain classes, our bounds are sharper than many previous ones in the literature.

A GENERALIZATION OF ORDER CONVERGENCE IN THE VECTOR LATTICES
Authors: Haghnejad Azar Kazem
Published: September 2022

Let $E$ be a sublattice of a vector lattice $F$.$\left( x_\alpha \right)\subseteq E$ is said to be $ F $-order convergent to a vector $ x $ (in symbols $ x_\alpha \xrightarrow{Fo} x $), whenever there exists another net $ \left(y_\alpha\right) $ in $F $ with the some index set satisfying $ y_\alpha\downarrow 0 $ in $F$ and $ \vert x_\alpha - x \vert \leq y_\alpha $ for all indexes $ \alpha $.If $F=E^{\sim\sim}$, this convergence is called $b$-order convergence and we write $ x_\alpha \xrightarrow{bo} x$. In this manuscript, first we study some properties of $Fo$-convergence nets and we extend same results to the general case. In the second part, we introduce $b$-order continuous operators and we invistegate some properties of this new concept. An operator $T$ between two vector lattices $E$ and $F$ is said to be $b$-order continuous, if $ x_\alpha \xrightarrow{bo} 0 $ in $E$ implies $ Tx_\alpha \xrightarrow{bo} 0$ in $F$.

Published: September 2022

This research is motivated by similarity of basic equations of $F$-planar mappings of symmetric affine connection space $\mathbb A_N$ involved by J. Mike� and N. S. Sinyukov, and which have been studied by Mike��s research group (I. Hinterleitner, P. Pe\v ska, \linebreak J. Str\'ansk\'a) and almost geodesic mappings (specially almost geodesic mappings of the second type) ofthe space $\mathbb A_N$ involved by N. S. Sinyukov and which have been studied by many authors. We used the formulas obtained by N. O. Vesic to obtain invariants for special $F$-planar mappings in this article. These invariants are analogous to invariants of geodesic mappings (the Thomas projective parameter and the Weyl projective tensor).
SOME PROPERTIES OF THE SET OF ALL STRONG UNIFORM CLUSTER POINTS
Authors: Pehlivan Serpil
Published: September 2022

The aim of this paper is to establish some relationship between the set of strong uniform statistical cluster points and the set of strong statistical cluster points of a given sequence in the probabilistic normed space. To this aim, let the uniform density be on the positive integers N for a sequence in the probabilistic normed space, that is, cases as equal of the lower and upper uniform density of a subset of N. We introduce the concept of strong uniform statistical cluster points and give a new type convergence in the probabilistic normed space. Note that the set of strong uniform statistical cluster points is a non-empty compact set. We also investigate some properties of the set all strong uniform cluster points of a sequence in the probabilistic normed space.
ON BOUNDEDNESS WITH SPEED λ IN ULTRAMETRIC FIELDS
Authors: Pinnangudi Natarajan Narayanasubramanian
Published: September 2022

In the present paper, K denotes a complete, non-trivially valued, ultrametric (or non-archimedean) field. Entries of sequences, infinite series and infinite matrices are in K. Following Kangro [2, 3, 4], we introduce the concept of boundedness with speed λ or λ-boundedness. We then obtain a characterization of the matrix class (mλ , mµ ), where mλ denotes the set of all λ-bounded sequences in K. We conclude the paper with a remark about the matrix class (c λ , mµ ), where c λ denotes the set of all λ-convergent sequences in K.
INTERSECTIONS OF SURFACES OF REVOLUTION
Authors: Veličković Vesna I.
Published: September 2022

In this paper, we deal with surfaces of revolution and their intersections. We start with the surfaces of revolution RS that have their axis along the x3–axis and find intersections with a line, a plane, and then intersection of two such RS. Furthermore, we apply formulas for the intersection with a line to determine the visibility of RS. Later we develop formulas for the intersection of two surfaces of revolution that have their axis along different arbitrary straight lines, and, as a special case, the intersections of two spheres and intersections of general surface of revolution with a sphere and a surface given by an equation. We apply our own software to the graphical representation of all the results we present.

Authors: Jelenković Predrag , Hadžović Miljan , Đorđević Stefan , Ilić Predrag , Lilić Ana
Published: September 2022

The student population is one of the most sensitive populations today, whereby it is necessary to consider the relationship between health and physical activity in order to improve students’ quality of life. In addition to physical inactivity, health status is adversely affected by constant technological innovations and excessive socializing, consumption of alcohol, tobacco and narcotics. The aim of this study was to determine the differences between the communication approach and attitudes of first- and fourth-year students of the Faculty of Sports and Physical Education on the impact of sports on health and improvement of mental hygiene. Using a 60-item questionnaire, the study included 70 healthy respondents of both genders (Mean ± SD: 20.86±1.76 years). The respondents were divided into two subsamples, i.e. a group of first-year students (IG; n=34; F=15, M=19) and a group of fourth-year students (IVG; n=36; F=18, M=18). All obtained data are presented by descriptive parameters. The reliability of the survey in terms of internal compliance was tested by Cronbach's Alpha coefficient. The manifest space of attitudes was processed by the scaling technique. The Mann-Whitney U Test was used to determine differences in attitudes between first- and fourth-year students. For statistical significance of the differences in results between groups, the p<0.05 level of significance was used. The data were processed in the SPSS statistical package. The results of the study unequivocally confirmed the existence of a positive attitude among the student population about the impact of sports on health and improvement of mental hygiene, as well as that there are no statistically significant differences in most of the variables included in the testing (eight out of ten domains), i.e. that there is no great difference in the attitudes of first- and fourth-year students on the importance of sports for their psychophysical health.
THE CONCEPT OF SYMBOLIC BOUNDARIES – CHARACTERISTICS AND SCOPE
Authors: Krstić Nemanja
Published: September 2022

Although it is one of the building blocks of sociological analyses, the concept of symbolic boundaries has been undergoing a second revival over the last twenty-odd years. Following in the footsteps of theoretical and empirical work by Michèle Lamont, researchers have been rethinking the potential of symbolic boundaries for additional fleshing out and elaborating in areas that have proven to be most productive. In general, its development moves in both significant scientific directions, toward enabling the transformation of basic premises into a sequence of research questions and linking them to appropriate methods, so as to include a significant portion of social reality empirically. Additionally, there are also theoretical aspirations to expand it from within, developing different aspects of it on an abstract level so as to establish a base categorical schema that would either serve to synthetize existing literature or, even more importantly, to focus further research. Of equal importance is also the attempt to compensate for the limitations of the concept of symbolic boundaries (Lamont 1992) by combining it with another, believed by its advocates to be complementary to the former, that of social relationships (“double objectivity” – Bourdieu and Wacquant 2013), in order to simultaneously examine both the social and mental structures of social differences and social stratification.

GUIDELINE FOR CONSTRUCTING COMPOSITE INDICATORS THAT MEASURE CIRCULAR ECONOMY PERFORMANCE
Authors: Vranjanac Žarko , Velimirović Lazar , Stanković Miomir
Published: September 2022

Composite indicators are modern tools for evaluating, comparing, and measuring the performance of multidimensional concepts such as sustainable development, environmental protection, or circular economy among countries, regions, or cities. The core of composite indicators includes the mathematical relation of individual indicators pertaining to different dimensions of the observed concept. Importantly, composite indicators are constructed by means of various mathematical models, primarily multiple-criteria decision analysis, which allows the selection of adequate individual indicators within a composite indicator. This is followed by the selection of a suitable aggregation model and a careful selection of a system for assigning individual indicator weights. Subjectivity during decision-making should be avoided as much as possible, as it could lead to an imprecisely formed indicator. In addition, this requires a proper previous definition of indicator robustness, which explains the level of coverage of a specific concept, as well as potential restrictions that need to be listed in indicator notes. This paper discusses the key features of measurement using indicators and the application of composite indicators in circular economy. Guidelines are also provided for proper definitions and construction of composite indicators that measure circular economy performance, all for the purpose of improving the system for circular economy performance measurement.

After the 2015 release of Peter Wohlleben’s book The Secret Life of Trees, which soon became a best-seller, books on nature and trees swamped the German book market. This paper is an attempt to answer the question why a forester’s book met such positive reactions from the readership. This paper focuses on the symbolic and semantic traits of the tree, as well as its meaning in the cultural memory of the German people that Wohlleben relies on in his way of depicting trees. Taking into consideration the aim of the paper, the semiotic and cultural-historical methods have been implemented.
ENTREPRENEURIAL SELF-EFFICACY AND BUSINESS SUCCESS OF ENTREPRENEURS IN THE REPUBLIC OF SERBIA: A PILOT STUDY
Authors: Стошић Панић Данијела , Janković Milić Vesna
Published: September 2022

The entrepreneurial self-efficacy is generally considered to be an important determinant of the entrepreneurship as a career choice. Another stream of the research on entrepreneurial self-efficacy is focused on exploring the link between this construct and the entrepreneurs’ business performance. Present study tries to fill the gap within this research field in the Serbian context by examining the relations of the entrepreneurial self-efficacy of entrepreneurs operating in the Republic of Serbia to their business performance. The study explores the nature of the relationship between the entrepreneurs’ business success and their general entrepreneurial self-efficacy (captured by one holistic measure), but also between business success and different dimensions of the entrepreneurial self-efficacy. Results show that general entrepreneurial self-efficacy and different dimensions of this construct are positively correlated to business success both measured by net profit and by a composite indicator of business success. The exception is the entrepreneurial self-efficacy in finance which is negatively correlated to the composite index of business success. Nevertheless, in the majority of cases, the results show the existence of the hypothesized directions of the relationship.

Therapeutic horticulture (TH) is a non-invasive support treatment in which participants enhance their well-being through active or passive involvement in plant and plant-related activities. Positive effects of TH are mainly noticed in children and youth with intellectual disability (ID), while the effects of TH on adults with ID have not been extensively studied. The aim of this study was to determine the impacts of TH on psycho-social aspects of functioning in adults with moderate ID in institutional settings. The sample included 68 adults with moderate ID of both genders. The participants were divided into an experimental group (N=33), that participated in a designed ten-week program TH, and a control group (N=35). The Social Skills Rating System – SSRS (Gresham & Eliot, 1990) was used to assess social skills and behavioral problems and Self-Efficacy for Gardening Scale was designed for assessing self-efficacy. We compared the results before and after the intervention. The obtained results showed a significant decrease in different forms of problem behaviors, and an improvement of social skills and self-efficacy in experimental group. Results of this study provide the empirical proof for positive effects of TH on the improvement of the psychosocial well-being of adults with moderate ID in institutional settings. However, further research is necessary.
CULTURE, POWER AND STRUCTURE OF ORGANIZATION: AN INTEGRATIVE RESEARCH FRAMEWORK
Authors: Janićijević Nebojša
Published: September 2022

The aim of the paper is to develop an integrative research framework for analyzing the relationships between organizational culture, power, and structure. Organization is observed as a configuration of mutually consistent components, so the main research question emerges: How organizational components impact each other? In this paper, the answer to this question is given through the analysis of the interrelationships between organizational culture, power and structure by applying the metaphor of the hologram. We started from the position that an organization must be understood as a state arising from the processes at both individual and organizational levels. The organization members’ needs for affiliation, power and achievement generate psychosocial, political and functional actions at the individual level, as well as the same processes at the organizational level. These processes generate organizational culture, power and structure as elements of the organization. However, the key idea is that culture, power and structure are derived from the wholeness of organizational processes and therefore contain each other as a kind of hologram. As a result, culture legitimizes power and structure, power instrumentalizes culture and structure, while structure institutionalizes culture and power. The paper shows practical implications of an integrative research framework both through defining further directions for research into relationships between culture, power and structure, as well as through showing to the management of organizations why it is necessary to understand and take into account the mutual consistency between culture, power, and structure.
THE DEVELOPMENT OF PSYCHO-ONCOLOGY WORLWIDE AND IN SERBIA - FIRST STEPS AND FUTURE PLANS
Authors: Klikovac Tamara
Published: September 2022

Psycho-oncology is a well-developed field in developed countries around the world and in Europe, both theoretically and practically. Psycho-oncology refers to the provision of psychological and/or psychotherapeutic assistance and support to persons with malignant diseases and their families. Twenty-two world congresses in psycho-oncology have been held. The existence of many published books, peer reviewed journal articles, numerous courses and specialization in this area attests to the importance of progress in this field. This paper serves to highlight the development of psycho-oncology in the world, with special emphasis on the current state of the discipline in Serbia. The number of publications and scientific research in the field are still limited and the number of engaged professionals is insufficient to effectively implement psycho-oncology in the Serbian health system. Nonetheless, there is reason for optimism. Pursuant to Article 38, paragraph 1. of the Law on the Planning  System (Official  Gazette  of  RS,  No. 30/18), the  Government  of  RS  has  adopted  the  Program for the Advancement of Cancer Control in the Republic of Serbia for the period between 2020 and 2022. The Action Plan for the Implementation of the Program for the Advancement of Cancer Control pays special attention to the development and implementation of psychosocial services and their integration into oncological treatment. The plan specifically envisions the establishment of 6 and 8 psycho-oncological services and counseling centers in health institutions in the secondary/tertiary level, in which cancer patients are treated, in 2021 and 2022 respectively. If the intended plan is realized, it will be a huge step forward and the beginning of the systematic, earnest development of psycho-oncology in Serbia.
THE EXPANSION OF SERBIA IN THE FIRST HALF OF THE 12TH CENTURY
Authors: Đekić Đorđe
Published: September 2022

In Serbian historiography, the expansion of Serbia, or Raška (Rascia), in the first half of the 12th century at the expense of Byzantium, whose vassal it was, was recorded a long time ago. At the same time, it is recorded that Serbia was defeated three times by Byzantium (in 1127 – 1129, 1149 and 1150). Byzantium dealt with the problem of unruly vassals by annexing some territory at the beginning of the 11th century, relocating population (after 1129 and 1150), giving land to the Serbs settled along the Byzantine border (to Zavida, Primislav, Desa, Stefan Nemanja), and raising the number of soldiers Serbia was obliged to give for waging war (in 1150). The lands granted to Serbs between 1129 and 1143 spanned the area between Ras and Kopaonik, while those granted between 1150 and 1158/9 spanned the area between Kopaonik and the parishes (Serb. župa) of Toplica and Reka. The first expansion benefited Zavida, who received lands from Byzantium after acknowledging the Empirećs sovereignty, upon his return to Ras, which belonged to Byzantium at the time. The second expansion impacted at least a part of Zavida’s territory which Stefan Nemanja later received when he became a suzerain in Serbia. We hypothesize that the territories that Byzantium gave to the Serbs as its vassals did become part of Serbia at a certain moment and under certain conditions. The answer to the question of how this was possible even though Serbia was defeated by Byzantium may be that Byzantine emperors regarded Serbian rulers as their officials and Serbian lands as Byzantine provinces.
TOYS AS ARTIFACTS OF THE MATERIAL CULTURE OF CHILDREN AND CHILDHOOD: IMPLICATIONS FOR FUTURE RESEARCH
Authors: Semiz Marina
Published: September 2022

The aim of this paper is to generate implications for future research based on the overview and analysis of the findings of relevant social sciences and the humanities that focus on toys as artifacts of the material culture of children, and/or childhood, with special reference to pedagogical research. By material culture of children, we mean items and objects that children themselves make, adapt or modify to fit their interests and the needs of their games, whereas the material culture of childhood refers toobjects created by adults for children to play with. Toys can encourage different types of activities necessary for overall personality development, and can help children develop their cognitive abilities, their body and senses, gain knowledge, socialize, cultivate their emotions and appreciation of beauty, and develop their imagination and creativity. The potential of toys that children make themselves is reflected in the upbringing of creative, free, environmentally conscious and active members of society. Additionally,these toys allow children to build play, to perceivetheir own capabilitiesand restrictions, and to express their imagination, creativity and respect toward the environment, life and oneself.Future research approaches should be directed toward: a) toys as artifacts of the material culture of children, i.e. objects that children themselves make and use for the purposes of play, learning and development; b) integrating the perspective of children and adults with regard to toys, because the distinction between material culture of children, and material culture of childhood is conditional; c) understanding social practice, as well as different discourses related to process of making toys of children building toys by themselves, or through cooperation with adults; d) qualitative research on the design and application of educational toyscreated by adults for children to play with; e) examining the possibilities and the potential of integrating the so-called improvised toys into the family and institutional context; and f) initiating evaluative studies and integrating the values and content of local culture into the preschool and school curricula.

In this paper, we consider the response of the education system of the Republic of Serbia to the COVID-19 epidemiological crisis in relation to the teaching process and distance learning activities in primary schools in Serbia. We examine learning through the televised programs of Serbia’s public broadcaster and other related internet services. The aim of this research is to estimate the quality of the teaching process and distance learning in primary schools. In accordance with the purpose of the research, a questionnaire about the educational experience and practices in primary schools during the spring and autumn of 2020 was created. The questionnaire is designed for school principals, teachers, students and parents/legal guardians of students. In total, 28186 people participated in this study conducted in March and April 2021. The results show that most schools used online resources efficiently despite the initially low digital competencies of teachers and students. Limited access to the internet and digital resources, as well as difficulties in engaging students, were gradually overcome during the fall of 2020. Based on the results of this research, we formulated the most important recommendations for the organization of distance learning and its future integration in the hybrid model of teaching and learning in school practice.
Acoustic Noise Emission in Wind Turbine: An Overview

Published: September 2022

Abstract: Wind energy embarks its development from the California era to the construction of huge onshore and offshore wind farms worldwide, highlighting the main challenges of wind energy applications while meeting the target 1000 GW of wind power by 2030. Though wind energy is considered a techno-economically matured energy, it is not entirely free from impacts on the environment and human health. Concurrently, large and small wind turbines are emerging even closer to human habitats, where acoustic noise would be of greater concern. Noise regulations and standards can effectively and fairly facilitate decision-making processes if developed and followed properly. For instance Denmark has a special legislation concerning wind turbines, while others like Sweden, and have used recommendations originally developed for different noise sources. In Germany, the noise level could be related to absolute level or background noise level (standardized, measured or related to wind speed) as in France. There showed a correspondence between sound pressure level and noise annoyance in the field studies performed across the globe among people living in the vicinity of wind turbines. Globally the annoyance and adverse health effects are analyzed by approaches such as epidemiological studies that rely on masked survey and clinical case studies. Wind turbine noise its propagation, relevant regulations, and impacts from wind farms were reviewed in this paper by summarizing existing studies. The intention of this paper is to provide state-of-art about wind turbine noise associated with wind turbines/farms to developers and planners.
