Authors: Ahmed Md. Dilsad , Ho Walter King Yan , Van Niekerk Rudolph Leon , Sulz Lauren , Begum Shaheen 
Published: July 2020

Abstract
Motivation is likely a pivotal factor contributing to sports participation. In India, because of the unsupportive sports/physical education environment, girls participate less in sports and other physical activities than boys. Therefore, embedding a planned healthy environment with good social support may maximize and, consequently, increase their participation in various sports and physical activities. Considering this unabated dialogue and assuming that motivation is a pivotal need for female sports participation, this study examined the differences in motivation to participate in sports among female adolescents across three age categories: early (11–14 years old), middle (15–18 years old), and late (19–21 years old) adolescence. A total of 528 female adolescents from Assam, India participated in the study. Participation in physical education courses was the criterion for the participants, and they were invited to complete the Participation Motivation Questionnaire. A factor analysis with direct oblimin rotation using the maximum likelihood extraction method yielded a 23-item, five-factor structure that exhibited moderate internal consistency. An ANOVA revealed significant differences across all three age categories regarding all the extracted factors. Moreover, t-tests of all sub-factors identified significant differences between the two achievement levels of district-level and inter-district-level athletes. This study provides sound psychometric and comparative results that are useful for education and formative reviews in applied settings and research purposes. It also serves as a measurement tool for embedding motivation to participate in physical activities and sports among female adolescents and the development of strategic ideas to assist female adolescents from less privileged areas to experience healthy growth and a healthy lifestyle.

Authors: Touti Rodouan , Harrass Hicham 
Published: July 2020

AbstractIn this work, we used CR-39 and LR-115 type II solid-state nuclear track detectors to measure238U,232Th,222Rn and220Rn concentrations in Merzouga sand. The measured concentrations of238U and232Th in the studied sand samples vary from (332.59±16.62) mBq·cm−3to (335.54±20.13) mBq·cm−3and (80.43±4.02) mBq·cm−3to (84.75±5.08) mBq·cm−3, respectively. We evaluated the radiation doses to the skin from the application of different sand baths by the patients by using a model based on specific alpha-dose and alpha-particle residual energy concepts. The maximum total equivalent dose to the skin due to the238U and232Th series from the cutaneous application of different sand baths by patients was found equal to (148.12±11.85) µSv y−1cm−2

Abstract
Background: Ionizing radiation has an indispensable role in diagnostic radiology and clinical treatments. Apparently, medical exposure in diagnostic radiology pertains to be the preeminent man-made source of radiation.
Objective: The aim of the present scientific study is to calculate the Entrance Surface Dose (ESD) and Effective Dose (ED) in digital radiography in Mazandaran province.
Materials and methods: The study was performed on 3600 patients in digital X-ray rooms 15 hospitals and the required data were collected from two age groups (10>15 years and adults) in each projection. Based on the results of this study, ESD and ED were calculated for skull (PA), skull (lateral), cervical spine (AP), cervical spine (lateral), chest (PA), chest (lateral), abdomen (AP), lumbar spine (AP), lumbar spine (lateral), pelvis (AP), thoracic spine (AP) and thoracic spine (lateral) examinations. It was calculated using PCXMC software (version 2.0).
Results: In this study, mean ESDs for the 10-15 year group varied from 0.97±0.21 mGy to 3.62±1.38 mGy for chest (PA) and lumbar spine (lateral), respectively. For the adult group varied from 1.05±0.31 to 3.85±1.44 for cervical spine (AP) and lumbar spine (lateral), respectively. And also ED value was from in the range of 10.40 µSv to 378.46 µSv for skull (PA) 10-15 year group and abdomen adults, respectively
Conclusion: This survey revealed a significant variation in the radiation dose of digital radiology examinations among hospitals in Mazandaran province. Application of a dose reference level (DRL) could be an optimization procedure for reducing the patient’s dose in Mazandaran province.
Classification of Structurally Weak Rural Regions: Application of a Rural Development Index for Austria and Portugal
Authors: Hennebry Barraí , Stryjakiewicz Tadeusz 
Published: July 2020

AbstractThis paper aims to analyse to what extent the level and dynamics of development of rural regions located in two firmly different countries, Austria and Portugal, differ. In order to do this, an index to measure the ‘structural strength’ of rural regions was created. This index is a more holistic measure of socio-economic development than the traditional GDP per capita. After the identification of structurally weak regions in both Austria and Portugal, the paper compares them in the context of challenges faced by such regions.
Potential Conflicts in the Land-Use Planning Process: A Case Study of the Rural Commune of Oleśnica (Poland)
Authors: Grochowska Anna , Małecka Martyna 
Published: July 2020

Abstract
The purpose of this study was to identify compatibilities of land-use patterns resulting from adjacent functions within the rural commune of Oleśnica. The analysis was made based on the relevant studies of conditions and directions of spatial planning, as well as a field inventory. The results of the studies show that the applicable planning document became a potential source of spatial conflicts. On these grounds, a negative assessment was given to the functioning spatial planning system, which, according to the premises of spatial order and sustainable development, should prevent them. The existing incompatibilities are the result of issues with coordination of the local spatial policies. As a consequence, they cause an urban development chaos, lack of proper space shaping, environmental damage and lower the residents‘ quality of life.

Published: July 2020

Abstract
Ureje Dam, Ado-Ekiti has witnessed drastic reduction in the water storage capacity of its reservoir. It became imperative to determine the possible cause(s) of the reduction in storage capacity. Geophysical investigation involving the vertical electrical sounding technique of the electrical resistivity method was conducted in the upstream part of the dam. Five lithologic units that include the mud/suspended materials, such as sandy clay, clay, weathered/fractured bedrock and fresh bedrock, were delineated. The respective resistivity and thickness range of the units are 2–19 ohm-m; 147–206 ohm-m, 2–38 ohm-m; 47–236 ohm-m and 455–1516 ohm-m and 0.4–1.9 m; 0.5–2.5 m; 1.0–12.2 m; 7.3–16.4 m and ∞. The thickness of suspended materials, resistivity/thickness of weathered layer and the presence of near-surface impervious layer were used as the main indices for the spatial demarcation of the dam axis in terms of vulnerability to loss of impounded water. Using the cumulative response of the indices, the study concluded that the eastern to southeastern parts of the dam axis showed the highest indications of vulnerability to loss of impounded water.
Determinants of Industry 4.0 Technology Adaption and Human - Robot Collaboration
Authors: Porubčinová Martina , Fidlerová Helena 
Published: July 2020

Abstract
Aim of the paper is to analyse specific factors of human-robot collaboration and adoption to Industry 4.0 technologies in relation to working in mixed teams and in virtual work environment. Based on literature review and current findings in unified theory of technology acceptance and use of technology (UTAUT) model and its extensions, new endogenous factors might be included/considered, in a UTAUT model, namely emotional attitude (trust towards technology, perceived threat) and new moderators such as a location of organization and type of workplace-based training in organization. Team identification and self-extension process are intended as drivers for development of positive attitudes in human-robot collaboration and prerequisites of sustainable human-robot interaction. Regarding the findings in human-robot collaboration, the authors suggest including the type of personality and the attitudes towards Human-Robot collaboration among the extended factors of technology adoption within Industry 4.0 strategy. Emotional attachment acts as a relevant factor of successful Human-Robot collaboration that can be maintained by a support of team identification and self-extension process. For the development of positive attitudes in human-robot collaboration, principles of personalized design can be applied, e. g. engaging the workers in designing specific features of the robot. It can be supposed that specific models of technology adoption - as UTAUT/UTAUT2 will require new extensions in a context of work analysis in a virtual work environment, e.g. health and psychological assumptionsIn the paper, subjective assessment of the increase in well-being of the workers after the adoption of Industry 4.0 technologies is identified as one of the new Industry 4.0 outcomes within the human capital definition of Industry 4.0.

Outsourcing Workers in the form of a Subsidiary
Authors: Šantavá Eva , Schmacher Benjamin , Talnagiová Viktória , Sablik Jozef 
Published: July 2020

Abstract
Many production companies have fully adopted a lean management philosophy, but their finances and control departments also need to adapt to this trend. All departments must adapt to the changing requirements and reflect the new challenges in production management. The controlling has undergone a lot of changes. Downloading data is no longer the only task of a controller. Controlling can be integrated into the organizational structure of the company internally as well as externally. Our goal is to define the advantages and disadvantages of using an internal or external controller. To decide whether to outsource some of the process is not just a question of cost reduction or time reduction. Companies very often decide for outsourcing in case of processes, which require special “know how” or are key from the competitiveness point of view. Outsourcing therefore represents a strategic change. Cost savings are only a side effect.
A Web-Based 3D Simulation Platform Aimed at Policy Makers for Estimating the Effects of Urban Heat Islands
Authors: Wurzer Gabriel , Pont Ulrich , Lorenz Wolfgang E. , Swoboda Sigrun , Mahdavi Ardeshir 
Published: July 2020

Abstract
The prediction of microclimate effects within an urban context through simulations has previously been done through elaborate software packages that offer accurate results but require extensive domain knowledge and time for the preparation of a model. In day-to-day policymaking, however, these efforts may turn out to be a major limiting factor: Policymakers and city administrators need a quick tool that can predict the effects of urban interventions in a variety of possible scenarios rather than a full-fledged simulation study for a limited set of specific interventions. In our work, we have been seeking to address this mismatch in expectations by using the best of both worlds: We have approximated results from a full-fledged simulation that uses a Cellular Automaton running within a 3D city visualization. Policymakers can edit the urban context by changing cell types (placement of greenery, etc.), thus leading to scenarios that can be compared to the status quo. As a matter of fact, policymakers can use these comparisons to argue for measures that mitigate the effects of heat islands, without requiring extensive domain knowledge or the effort to prepare a simulation model.

Published: July 2020

Abstract
An analysis of a hydrological time-series data offers the possibility of detecting changes that have arisen due to climate change or change in land use. This paper deals with the detection of changes in the hydrological time data series. The trend analysis was applied at 58 stage-discharge gauging stations that are located throughout Slovakia, with the measurement period from 1962 to 2017. The Mann-Kendall test show a declining trends in the summer and a few rising trends in the winter in discharges. In the town of Banská Bystrica at a station on the Hron River, decades of discharges, air temperatures, and precipitation totals were analyzed. The five decades from the 1960s to the 2000s were used. The hydrological time data series were also analyzed by the Pettitt’s test, which is used to detect change points. The decadal analysis at the Banská Bystrica station shows an increase in the air temperature but insignificant changes in discharges and precipitation. Pettitt’s test identified many change points in the 1990s in the air temperature.

Published: July 2020

Abstract

Introduction
The aim of the study was to validate the Croatian version of the Sense of Coherence 29-item instrument (SOC-29) within a nursing population.

Methods
The cross-sectional study was conducted between December 2017 and June 2018 at the University Hospital Centre Sisters of Mercy (UHCSM) in Zagreb, Croatia. A total of 711 nurses participated in this study. Internal consistency reliability was evaluated using Cronbach’s alpha coefficient (α), while the structure of the questionnaire was verified by exploratory factor analysis (EFA) (method of extraction: principal component analysis (PCA)) and confirmatory factor analysis (CFA).

Results
The instrument demonstrated high internal consistency (α=0.885). PCA analysis has identified five factors that together account for 48% of the variance. However, the observed factors could not be interpreted. In the CFA, none of the models fitted well, although the fit of the three-factor model (CMIN/DF=4.786, CFI=0.767, RMSEA=0.073) was slightly better in comparison with the one-factor model (CMIN/DF=6.072, CFI=0.685, RMSEA=0.084). As the three-factor model in PCA has been shown to be uninterpretable, and all three factors were mutually positive and significantly correlated (correlation coefficients: 0.365–0.521), this indicated a single factor in the background. All items also showed saturation with the first factor (accounting for 25.7% of the variance).

Conclusions
The Croatian version of the SOC-29 instrument successfully fulfilled the necessary psychometric criteria for being used on the population of Croatian nurses. The study proposes that potential users use the single-factor structure.
Gender Influence on the Perception of Celebrity Endorsement
Authors: Lazăr Laura 
Published: July 2020

Abstract
Celebrity endorsement is a common instrument in marketing. Celebrities are also present in commercials, and this phenomenon is nowadays a trend. This kind of publicity has a high potential since customers are pulled into the VIPs. They are overpowered by their regular daily existence, so they need standards and good examples. This is the motivation for using superstar brand envoys in advertisings as an excellent promoting technique of brands and products. In the period of data and promotions, the tributes can get the consumers’ consideration in publicizing and to expand how the promoted item is being perceived. This is because of their fame, glamour, elegance and charisma. For this reason, the marketers are looking for popular, famous, beautiful, positive testimonials to drive a company’s image and its products. The celebrity brand ambassadors thus play a significant role in a brand’s advertisement and reputation, but also in the consumers’ lives. The stars’ everyday lives, their conduct, the products they use, affect the attitude of the customers of life and the decision to purchase. The purpose of this paper is to determine if celebrity endorsement works for all the consumers or the perception of this trend is different according to the gender of the people. Two groups of customers were asked about celebrity endorsement whether their appearance in ads affects their decision and the desire to purchase a product or not. Recent results have shown that there are still differences between the two categories of customers, men and women, in the perception of celebrity endorsement. All of them think advertising is important, and sometimes they change their choices according to a product’s advertisement. The difference is that women appear to believe more in the endorsements of celebrity brands and their impact effect on the product being marketed than men, who are more pragmatic and reticent about this trend.
The Influence of Oil Price on Renewable Energy Stock Prices: An Analysis for Entrepreneurs
Authors: Vrînceanu Georgiana , Horobeț Alexandra , Popescu Consuela , Belaşcu Lucian 
Published: July 2020

Abstract
This study investigates the relationship between oil price fluctuations and renewable energy stock returns using daily data on Brent crude oil prices and global renewable energy stock market indices between 29 November 2010 and 18 February 2020. The investigation is based on the existing evidence on positive correlations between stock prices and oil prices, but it also considers the shift from non-renewable to renewable sources of energy. A two-stage GARCH(1,1) model and a Granger causality test were applied. Our results show that volatility clustering is present in the renewable energy companies‘ stock prices, but, oil price volatility does not seem to induce any significant effects on returns‘ volatility. This might suggest that oil markets and renewable energy markets are rather disconnected, which means that the development of renewable energy businesses is less affected by potential shocks in the oil prices and markets. As a result, the exposure of companies and entrepreneurs in the renewable sector to an important source of macroeconomic volatility is reduced.
The Impact of Social Media Adoption by Companies. Digital Transformation
Authors: Onețiu Darius Daniel 
Published: July 2020

Abstract
This article highlights the adoption of social media by organizations and its consequences on the company’s performance. These topics of debate are becoming more and more common in the business environment. In fact, it is the main argument for which this paper relates the particularly important aspects of the adoption of social media (social networks) by organizations. In the following, important aspects that bring value to the organization, both by acquiring and by adopting social media in sales performance, have been structured. This research is built on a theoretical study, including as main terms of discussion: social media adoption and digital transformation. In the last part of the article, we have summarized and concluded these factors. We have identified how they can contribute to a more efficient orientation of sales performance, to increase the organizational management of the relationship and the connection between customers and the organization. Referring to the orientation towards “use of social networks” by organizations, we demonstrate that organizations are required to give high importance to understanding the organization’s customers and, of course, a high degree of relational performance. Another factor encountered in this theoretical research is ―digital transformation”. We debated this topic in order to easily make the transition to the adoption of “social media” by organizations. Following the theoretical research, we can say that today, digital transformation has special importance in the organization and the fact that a strong link has been created among social media, reality management and performance in relational sales.

Authors: Jackson Ilya , Tolujevs Jurijs , Kegenbekov Zhandos 
Published: July 2020

Abstract
Inventory control has been a major point of discussion in industrial engineering and operations research for over 100 years. Various advanced numerical methods can be used for solving inventory control problems, which makes it a highly multidisciplinary filed attracting researchers from different academic disciplines. This fact makes it a daunting task to subsume the gargantuan spectrum of literature related to inventory control theory in one treatise. In light of this fact, this paper focuses on the timeline of inventory control models with respect to methodologies behind deriving optimal control parameters. Such methodologies include analytical approaches, optimal control theory, dynamic programming, simulation-based optimization and metamodel-based optimization.
