Authors: Petroni Giulia , Brodocz Lukas , Passarett Alfredo , Zanza Alessio , Testarelli Luca , Cicconetti Andrea
Published: December 2022

Background: Hyperparathyroidism (HPT) is a common endocrine disorder with potential complications on the skeletal, renal, neurocognitive and cardiovascular systems. Its association with the lack of osseointegration of dental implants has not been described in the medical literature. Case presentation: This case report aims to discuss two cases of dental implant loss in which a high level of parathormone (PTH) was found in the absence of any other systemic or local comorbidity, suggesting the possible correlation between HPT and implant. Both patients were referred to the clinic complaining about prosthetic complications, gingival inflammation and mobility of the dental prosthesis. After a Cone-Beam computed Tomography evaluation, all implants of both patients were removed for rejection arising from periimplantitis and then four implants were inserted in the patient 1 and five implants in the patient 2. For both patients short implants (Bicon LLC, Boston, Massachusetts, USA), featured by 4 mm in diameter and 5 mm in height, were used and the prosthesis substructure was made of Trinia® (Bicon LLC, Boston, Massachusetts, USA). During the fifth year, the patients reported complications and the implant treatment failure. In order to establish the causes of failure, a thorough investigation was performed. Since no causes were detected, the patients were required to perform a blood test to evaluate bone metabolism and specifically to assess parathyroid-hormone levels (PTH), calcium levels and vitamin D. Results: The results of the blood tests showed normal calcemia, vitamin D deficiency and elevated PTH levels in both patients. After an endocrinologist's consultation, secondary hyperparathyroidism was diagnosed. Conclusion: It is reasonable to assume that the loss of osseointegration of dental implants can be correlated with the effects of HPT.

Authors: Parkar Sujal , Sharma Abhishek
Published: December 2022

Aim: The aim of this study was to assess the magnitude of various oral health indicators. Further, to identify the oral health indicators as a predictive factor for the quality of life among head and neck cancer patients. Methods: A cross-sectional study was conducted among 400 head and neck cancer patients attending tertiary cancer center. The European Organization for Research and Treatment of Cancer and Head and Neck specific (EORTCQLQH&N35) module was used to assess the patient's quality of life. Oral health indicators (oral hygiene practices, oral complication, dental visits, oral rehabilitation) were recorded through oral examination and personal interviews. Spearman's correlation coefficient was used to assess the correlation between oral health indicators and different scales of QoL. Multivariate linear regression by a backward stepwise method was applied to assess the influence of oral health indicators as a predictive factor for QoL. Results: Out of 400 patients, 54.25% of patients reported having one or another form of oral complication. Periodontal problems were the common oral complication among the patients. There was a weak correlation between oral health indicators and most of the scales of EORTC QLQ-H&N35. Theoretically, linked oral health indicators were found to be significant predictive factors. Conclusion: The results show that there was a high magnitude of poor oral health indicators. Oral health indicators also acted as a significant predictor of quality of life. A multi-disciplinary approach is desirable for the improvement in oral health thus improving the overall quality of life among head and neck cancer patients.

The export performance and competitiveness of the Euro area's periphery
Authors: Kovačević Radovan
Published: December 2022

This paper examines the impact of the selected factors on the real exports of goods and services in the several Euro area (the eurozone) peripheral economies. There are five countries in the sample (Italy, Spain, Portugal, Ireland, and Greece). The time period from 2000 to 2019 is considered. The research is aimed at providing robust estimates of the long-term relationship between the real exports of these countries and the selected explanatory variables using panel data analysis. The coefficients of the cointegration export equation were estimated using the FMOLS and DOLS estimators. Using the FMOLS estimator, the estimated coefficient of the real effective exchange rate is negative (-0.80) and of the variable foreign demand is positive (2.25). The coefficient of the real effective exchange rate confirms the fact that, from the point of view of the eurozone peripheral members, the overestimated real value of the Euro has a disincentive effect on their real exports. The estimated coefficient of foreign demand suggests that the real export of goods and services (volumes) of the eurozone peripheral members increases by 2.25% when the real GDP of the EU increases by 1%. The real export elasticity of the eurozone periphery countries is higher for foreign demand (income elasticity) than for relative price changes (price elasticity). Reductions in wages and prices in peripheral countries have led to redistributive effects in favor of the core.

Authors: Afolabi Joshua , Olanrewaju Blessing , Adekunle Wasiu
Published: December 2022

The Nigerian economy has been repeatedly hit by macroeconomic shocks, primarily owing to its overreliance on crude oil and poor resource management. Given the limited resilience capacity of Nigeria's economic sectors, this study examined the sensitivity of these sectors to macroeconomic shocks using the Vector Autoregression (VAR) and the Vector Error Correction (VEC) models in whose frameworks the study was carried out for the period between 2010Q1 and 2021Q4. The findings revealed the high responsiveness of the services and agricultural sectors to fiscal shocks, as well as the high sensitivity of the industrial sector to interest rate shocks. Also, the services sector was found to be more resilient to oil price shocks than the other sectors. Therefore, this study advocates for developing strategies to boost sectoral productivity and skillfully blend the fiscal and monetary policies so as to cushion the effects of macroeconomic shocks. Overall, this study provides the evidence of the sectoral effects of macroeconomic shocks in Nigeria.

Authors: Kocić Milan , Šapić Srđan , Sofronijević Katarina
Published: December 2022

Using websites for commercial purposes has been noticeable in numerous areas in recent years, including the organic food market, among others. The era of digitalization has implied that an increasing number of consumers form their views on organic food based on information that is marketed via websites, instead of going to traditional stores. In accordance with that, the aim of the paper is to examine whether the quality of a website, measured by its usability, design and the quality of information, affects consumers' cognitive and affective attitudes towards organic products. In this paper, exploratory factor analysis is carried out along with multiple regression analysis. The research results indicate that, in the organic food sector, it is very important to have a website which is both usable and visually appealing, simultaneously containing quality and updated information, which all can greatly influence the formation of users' attitudes towards organic food, their attitudes being made of the rational emotional dimensions as well. The contribution of this research study is particularly significant bearing in mind the fact that attitudes towards organic food are mostly examined in a traditional environment, not so much in an online environment.

Published: December 2022

The development of information and communication technologies has influenced the lifestyle of consumers. Online shopping saves time and seemingly money, because it allows consumers to shop from home at any time 24/7/365. Today's consumers are online consumers, but the difference in generations indicates the need for consumers as such to be profiled and analyzed. The fact that 2020 is marked as the Corona year gives special importance to the analysis of online shopping intention. Measures to slow down the pandemic, among other things, were distancing, quarantine, isolation, so online shopping is becoming more convenient or the only possible option. The willingness of consumers to shop in a pandemic has accelerated the online shopping process in many countries and led to the creation of a new pattern of consumer behavior. The subject of this paper is Generation Z, which mostly follows the development of information and communication technologies. The aim of the research is to confirm the connection between the lifestyle of Generation Z, primarily students, as members of the dominant academic environment and online shopping. A well-structured questionnaire adopted from various previous studies was conducted through an online survey of 320 students across Serbia. Consumer lifestyle identification statements include activities, interests and opinions (AIO), where activities relate to a person's daily activities in terms of entertainment, leisure and shopping, interests relate to the importance a person has for fashion, food, recreation, media, and opinions focus on social issues, products, future, culture. The study uses a simple random sampling technique. The study performs a research factor analysis to isolate the factors that have emerged as bearers of consumer lifestyle characteristics.

Macroeconomic determinants of loan default rate in banking sector of the Republic of Serbia
Authors: Drljača-Kanazir Svetlana
Published: December 2022

In literature, there is inconsistent view of how the size of a company affects the level of credit risk. The aim of this research is to to determine whether the exposure to systemic risk increases with the size of the borrower. Empirical analysis of the time series of loan default rates, as dependent variable, on the one hand, and macroeconomic factors, as regressors, on the other hand, is based on the error correction model. Parallel to this, a panel data analysis was applied where panel units are defined at the level of the risk segment of the loan portfolio. Research results confirm that there is statistically significant impact of macroecnomic determinants on loan default rate in banking sector of Republic of Serbia. However, in the segment of small and medium-sized enterprises, the adjustment coefficient is not statistically significant. Along with this, in the short run, there is a statistically significant negative impact of the one-quarter lagged default rate on the default rate in the SMEs segment. Based on the research results, it can be inferred that the credit risk of the SMEs segment is the most resistant to the influence of macroeconomic factors. SME are the most flexible because they are not burdened by size, and on the other hand, they are not endangered as micro businesses by the risk of concentration of one large customer and weak negotiating position in relation to creditors and suppliers.

The aim of this research is to determine the level of importance and performance (usage level) of hotel crisis management measures during the different phases of a crisis: Before-Crisis phase, During-Crisis phase, and After-Crisis phase, and to determine the significant gap between these two levels by surveying the managers of the high-category hotels in Serbia. The questionnaires were filled out by the managers of 162 high-category hotels in Serbia (four-and five-star hotels) during the Covid-19 pandemic in 2020. The Covid-19 pandemic caused the sharpest decline in the tourism sector around the world, thus the crisis management applied in tourism enterprises will have a crucial role for the tourism industry in surviving this pandemic. The hotel managers' responses were analyzed by using the Statistical Package for the Social Sciences (SPSS). The applied methods include the descriptive statistical analysis, paired-samples t-test, and Importance-Performance Analysis (IPA). Empirical results showed that hotels were adopting various crisis management measures during the different stages of the crisis, also, the implementation of certain measures significantly affected the business operations of hotels. In addition, hotel crisis management considers that measures implemented during the Before-Crisis phase, During-Crisis phase, and After-Crisis phase are of great importance.
Fatigue analysis of preloaded bolted joints
Authors: Welch Michael
Published: December 2022

This article presents Wöhler plots, or S-N curves, for use in the analysis of bolt fatigue of preloaded bolted joints. Preloaded bolts under cyclic loading have a high mean stress with a small alternating stress. This is combined with a large stress concentration at the thread root. The method of fatigue analysis presented uses S-N curves with a zero mean stress. The high mean stress experienced by the bolts is accounted for using a function to calculate a damage-equivalent stress. Notch sensitivity was considered to modify S-N curves for materials with chemical compositions encompassed within the material specifications for high strength bolts. This produced S-N curves for stress concentrations relevant to bolt threads. Curve fitting techniques were used to express these curves as a function of the equivalent stress and stress ratio. An estimate of residual stresses in bolts produced by thread rolling was made. The work provides a practical method of calculating fatigue life.
Nonlinear free vibration analysis of non-uniform axially graded beam on variable elastic foundation
Authors: Lohar Hareram , Mitra Anirban
Published: December 2022

The present work investigates the nonlinear free vibration of an axially functionally graded (AFG) beam supported on the variable foundation. The beam geometry is non-uniform, with a linear cross-section variation along the length. The beam material is graded along the axial direction following the power-law relation. A Winkler type of variable elastic foundation is taken, in which variation of stiffness is considered along the length of the foundation. Geometrical nonlinearity produced by the beam's large-amplitude deflection is also considered. To attain the desired objectives, the problem is divided into two parts. The static problem is solved first, then a subsequent free vibration analysis is executed on the statically deformed beam configuration. The governing differential equations of the system are derived using suitable energy methods. A numerical technique of direct substitution with relaxation is utilized to obtain the solution of the derived nonlinear differential equations. A suitable validation study is presented to ensure the appropriateness of the present methodology. Benchmark results are also presented by means of natural frequency, backbone curve, and mode shape plot to investigate the influences of elastic foundation, material gradation, and non-uniform geometry on nonlinear vibration.

Authors: Polishchuk Mikhail , Tkach M. , Stenin A.
Published: December 2022

The current stage of development of robotic systems is characterized by the use of anthropomorphic robot designs, the functions of which are as close as possible to human capabilities. This trend is explained by the need to give robots universal capabilities when performing various technological operations. The article proposes a fundamentally new design of a walking robot and describes a model of its functioning. This design allows the robot to move in an angular coordinate system, which is typical for humans. The main motivation for creating such a robot is to reduce the number of drives for the kinematic chain of the walking mechanism. The article presents the results of mathematical modeling and recommendations for the design of anthropomorphic walking mechanisms. The engineering formulas and diagrams presented in the article for calculating force loads make it possible to create various modifications of walking robots that have the property of adapting to an arbitrary surface topology for moving a mobile robot. The economic effect is achieved by reducing the number of electric motors for the robot's leg joints and, consequently, by reducing the total cost of the walking robot.

Published: December 2022

Nanocomposites based on siloxane and silicon(IV)oxide nanoparticles (with a hydrophilic and hydrophobic surface) were synthesized to design the desired final properties of the composite material. Masterbatch, a mixture of siloxane containing vinyl functional groups and reinforcing fillers, was added to improve the mechanical properties and topology of siloxane networks. Silicon(IV)oxide was added in amounts of 1, 5, 10, and 20 wt% and masterbatch in amounts of 5 and 10 wt% to examine the effect of the amounts of fillers and masterbatch in the synthesized samples. Fourier transform infrared spectroscopy was used to analyze the chemical structure of the obtained materials. Transmission electron microscopy (TEM) was used to examine the dispersion of filler particles in siloxane nanocomposites. To examine the thermal stability and phase transition temperature of siloxane materials, thermogravimetric analyzes (TGA) and differential scanning calorimetry (DSC) were performed. The addition of masterbatch did not lead to a significant difference in melting temperature, but stoichiometry was disturbed, which decreased the thermal stability compared to samples without masterbatch. The addition of masterbatch to nanocomposites with hydrophilic fillers increases both elongations at break and tensile strength. According to the results, the combination of masterbatch and nanofillers affects the properties of siloxane materials, which could enable obtaining materials with the desired properties.

Published: December 2022

Even though it contains high levels of many important nutritive compounds, whey has not been widely accepted by consumers due to its unappealing taste and texture. Whey fermentation could improve its sensory properties and result in a functional beverage with appealing characteristics and a clear potential to replace traditional functional milk-based beverages. Therefore, this work aimed to develop a goat whey-based functional beverage fermented with kefir grains and to examine the influence of fermentation temperature and inoculum size on the overall sensorial acceptability of the product and its antimicrobial activity. Response surface methodology along with the central composite design was used to estimate the individual and combined effect of temperature and inoculum size on lactic and acetic acid, ethanol, antimicrobial activity and overall sensory acceptability of the obtained beverage. The experimental data for lactic and acetic acid, antimicrobial activity and overall sensory acceptance of beverage were fitted to a quadratic model, while a linear 2FI model was proposed for the ethanol content. Temperature and inoculum size have been found to affect the quality of the obtained beverage. Multi-response optimization provided an optimum solution for the production of the most acceptable beverage with the highest antimicrobial activity. According to desirability criteria, with overall desirability of 0.79, the following fermentation conditions were proposed for the fermentation of goat whey using kefir: temperature of 27.5 ° C and inoculum size of 7.36%. Proposed values were validated confirming the minimum deviation of experimental and predicted values.

Some of the specific characteristics of quince fruits, such as the high content of pectin substances and relatively low content of fermentable sugars, lead to certain challenges during alcoholic fermentation. The aim of this research was to evaluate the effect of quince variety on fermentation dynamics, alcohol yield and chemical composition of produced spirits. Nine quince varieties grown at the experimental field "Radmilovac" (University of Belgrade - Faculty of Agriculture), were used in this study: Vranjska (SRB), Leskovačka (SRB), Morava (SRB), Pazardžijska (BLG), Hemus (BLG), Asenica (BLG), Portugal (POR), Triumph (BLG) and Rea's Mammoth (USA). The investigation was carried out in 2018. Soluble solids content in quince fruits was in the range from 12.90% (Pazardžijska) to 16.80% (Morava). Total sugars and total acids expressed as malic acid were in the range from 6.74 % and 0.53% w/w (Pazardžijska) to 9.76 % and 1.27% w/w (Morava), respectively. The highest alcohol content had spirits made from quince varieties Leskovačka and Asenica (9.88 litres of 40% vol. alcohol from 100kg of fruit), while the lowest alcohol content had spirit made from variety Rea's Mammoth (7.20 litres of 40% vol. alcohol from 100 kg of fruit). All spirit samples had methanol content (up to 1350 g/hl, calculated at 100% of alcohol) and other quality parameters in accordance with the legal regulations.

Authors: Adu Kwarteng , Plata Lerma , Ratilla Mark , Novak Petr , Zlamal Lukas
Published: December 2022

Digitalization has been identified as a core growth driver for small and medium enterprises (SMEs) in this digital era. This study investigates the drivers and barriers aligned with the tendency of owner-managers of SMEs to adopt digitalization. A conceptual framework is developed that extends the unified theory of acceptance and technology (UTAUT) with an anxiety-digitalized environment as a moderating factor of SME owner-managers' intention to adopt digitalization. A quantitative methodology is used to gauge responses from 89 respondents (owner-managers). Additionally, the variance-based structural equation modelling approach (PLS-SEM) is used to analyse and validate the proposed model. Results show that attitude positively mediates the relationship between performance expectancy and intention to adopt digitalization. However, effort expectancy and facilitating conditions were found to negatively influence attitude and intention to adopt digitalization. On the contrary, the results obtained did not confirm the significance of an anxiety-digitalized environment in moderation analyses. Consequently, the overall structural model accounted for 51.1% of the variance in the intention to adopt digitalization among SMEs. This study has theoretically and practically contributed to understanding owner-managers' intent to adopt digitalization of SMEs in the Czech Republic.

Authors: Panjaitan Roymon , Hasan Muhammad , Vilkana Resista
Published: December 2022

The level of productivity should be increased and maintained to sustain the success of micro, small and medium enterprises (MSMEs). Furthermore, entrepreneurial resilience requires advanced technological innovation capabilities to avoid continual external disasters. Therefore, this research explores the connection between entrepreneurial resilience, disaster-resilient MSMEs, and new ideas on complex technical innovations to modulate entrepreneurship. Partial Least Squares are used to process 177 MSMEs respondents in Central Java, Indonesia and the findings successfully bridged the gap between entrepreneurial resilience and disaster-resistant MSMEs. The is mediated by sophisticated technology innovation capability. Furthermore, corporate owners and managers are concerned with the ongoing adaptation and creation of complicated technologies concerning sophisticated innovation capabilities. These findings indicate that entrepreneurial resilience contributes to sophisticated technological innovation capability. The findings also show that entrepreneurial resilience contributes to disaster-resilient MSMEs and demonstrate the importance of understanding how entrepreneurs survive during conditions of uncertainty. This theoretical conclusion gives rise to a new competitive resource advantage theory perspective in which sophisticated technology's inventive capacities might be strengthened when entrepreneurial resilience is stronger. The entrepreneurial resilience can improve when corporate organizations or MSMEs players have advanced technical resource capabilities.
