La configuración de capillas y altares en el monasterio de Santes Creus / The configuration of chapels and altars in the Monastery of Santes Creus
Authors: Segarra Calderer Marta 
Published: January 2020

Resumen: La configuración de la topografía monástica tiene uno de sus puntos más representativos en la colocación de capillas y altares repartidos por todo el espacio de la clausura, que permitían a la comunidad monástica desarrollar su actividad litúrgica.En el monasterio de Santes Creus, el conocimiento de dichos espacios y su evolución nos permite, a la vez, establecer una cronología precisa de la evolución arquitectónica del propio monasterio y determinar los usos y funciones de las diferentes estancias monásticas. Sus cambios nos plantean un reto importante que solo podemos atisbar a partir de ciertos vestigios materiales y de la documentación conservada.Abstract: The configuration of the monastic topography has one of its most representative points of study in the placement of chapels and altars scatteredthroughout the space of the closure, which allowed the monastic community to develop its liturgical activity.In the monastery of Santes Creus, the research about these spaces and their evolution allows us, at the same time, to establish a precise chronology of the architectural evolution of the monastery itself and also to determine the uses and functions of the different monastic rooms. Their changes pose an important challenge, sometimes only recognizable through material remains and preserved documentation.

Published: January 2020

Compreender os mecanismos que regulam a dinâmica das populações espacialmente estruturadas é um desafio crítico para os ecólogos e gestores de conservação. A dinâmica de populações é um ramo da ecologia que estuda as populações como sistema em atividades, relacionando as influências ambientais com a distribuição e abundância dos indivíduos e suas interações com o ambiente. O presente artigo é uma revisão bibliográfica, com o objetivo de identificar produções científicas relevantes sobre dinâmica populacional. Para isso, foram utilizados periódicos revisados por pares, na base de Periódicos Capes. A pesquisa foi realizada em junho de 2019, utilizando-se as palavras-chave para título contendo: "population dynamics" e no assunto “ecology”, a partir de 2014, quando o texto completo estava disponível. Foram considerados como critérios de exclusão os artigos publicados antes de 2014. Após a leitura dos títulos dos artigos, foram selecionados 34 artigos que foram lidos na íntegra. Em livros disponíveis no acervo da biblioteca da Universidade Federal do Triângulo Mineiro, foram selecionados quatro livros no tema dinâmica populacional. O referencial teórico aborda os aspectos da dinâmica de populações, tabela de vida, formas de crescimento e interações populacionais. Ressalta-se a necessidade de novos estudos que ainda possuem lacunas, que venha complementar e contribuir para o conhecimento de organismos que faltam ou ainda não possuem registros de estudos. Palavras-chave: Taxas de Natalidade e Mortalidade. Atributos Populacionais. Dispersão. AbstractUnderstanding the mechanisms that regulate the dynamics of spatially structured populations is a critical challenge for ecologists and conservation managers. Population dynamics is a branch of ecology that studies populations as a system in activities, relating environmental influences to the individuals’ distribution and abundance and their interactions with the environment. This article is a bibliographic review, aiming to identify relevant scientific productions about population dynamics. Thus. peer-reviewed journals were used in the Capes Periodicals base, the research was conducted in June 2019, using the keywords for title containing "population dynamics" and in the subject "ecology", from 2014, when the full text was available. Exclusion criteria were: articles published before 2014, after reading the article titles, 34 articles were selected that met the initially proposed criteria and were read in full. In books available in the library collection of the Federal University of Triângulo Mineiro, with a search for the dynamic population theme, 4 books were used. The theoretical framework addresses the aspects of population dynamics, life table, forms of growth and population interactions. It is emphasized the need for further studies that still have gaps, which will complement and contribute to the knowledge of organisms that are missing or do not have study records.

Entrepreneurship in Greece
Authors: Vasilopoulos Athanasios , Tsitsakis Christos 
Published: January 2020

Back in 2008, when the global economic crisis started, Greek companies and generally the corporate sector faced numerous difficulties. A lot of businesses closed, and the unemployment rate was significantly raised. The aim of the following paper is attempting to study the current situation of entrepreneurship in Greece, to find the problems that arose from the crisis and to acknowledge any future chance of positive development. Our results from the conduction of the two surveys have indicated that the entrepreneurs who answered our survey are facing a lot of problems in extroversion, due to the high taxation and the general market crisis. Also, only half of them had any advisory support at the beginning of their business. Similarly, their answers showed that it is more possible for them to close their business soon, as they are more pessimistic for better conditions and environment in entrepreneurship, in the near future. On the other hand, the results for the non-entrepreneurs, who answered our second survey, showed that a lot of them were in favor of making a company but they hesitate because of the taxation system, the bureaucracy and the lack of knowledge in business sector. The key to making entrepreneurship in Greece approachable is to rebuild the tax system and make it more sustainable for the businesses. Similarly, it is important to have financing support through private and public initiatives and help new innovative businesses and startups begin operations. Lastly, Greek Government must make a new proactive environment to protect all low and middle range businesses from terminating their operation.

Authors: Miron Dumitru , Șeuleanu Dragoș 
Published: January 2020

The multipliers of paradigm shift in economy are abundance, change of micro and macroeconomic equilibrium, and increased intensity in creativity at the level of economic processes. Authors starts from the hypothesis that in the field of economics and business, a number of enthusiastic approaches to paradigm shift must be taken with some reservations as functional market have their specificity, the public choice logic is very well represented, the idea of social learning is present more than in other fields and the principle of economic rationality has great applicability. The most important characteristics of the new European industry are: is based on three pillars: strong educational system, scientific research and high-tech; advanced research is an integrative industry; the results of the advanced research are an Open Source. The analysis is based on the quadruple helix logic, authors analyzing the Extreme Light Infrastructure - Nuclear Physics (ELI-NP). As development of a country could be based on few advanced research projects and it is possible to use this experience for the whole region, new engines of the European economy, will be: nuclear research, extreme intensity light research and astronautics, the new industry will develop a large range of activities and jobs which will modify the labor map and the relocation of large companies to Europe will be one of the concrete result of the stimulating the advanced research.

Exploring Decision Rules for Election Results by Classification Trees
Authors: Deveci Kocakoç İpek , Keser İstem 
Published: January 2020

This study explores the most important socio-economic variables determining the voting decisions of the provinces in Municipality Elections by using classification trees. We collected data on many potential variables that may affect voting decisions in favor of a political party. Each province’s economic, geographic and demographic data is taken into consideration as independent variables. The dependent variable is the winner party in 2014 Municipality Elections. Data set consists of 81 provinces’ data on 69 variables. The aim of the study is to find which variables affect voting decision the most and try to find a pattern that may lead political campaigns. Amongst many classification algorithms, we used C5.0 algorithm coded in R. It helps us explore the structure of a set of data, while developing easy to visualize decision rules for predicting a categorical (classification tree) or continuous (regression tree) outcome. The C5.0 algorithm determines the separation criterion with the greatest information gain in each decision node and performs optimal separation.
Since our data size is small, we used k=1000 trials (estimations) and then summarized them to provide more robust results. By choosing C5.0 algorithm’s sub-trial size as 5, 5000 trees are formed and the mean of all importance scores of all trees formed are calculated and interpreted. The most important independent variables discriminating the voting decision are found to be the result of the previous elections, mean household population, proportion of population between ages 15 and 19, electricity consumption per person, and proportion of population between ages 55 and 64.

Operating Room Management after 2008 Economic Crisis in Italy: A Literary Review
Authors: Rochira Andrea , Ubiali Andrea , Buccioli Matteo , Perger Peter 
Published: January 2020

The 2008 financial crisis has changed administration methods of various activities and productive services, including health services. In fact in Italy it was necessary a deep reorganization of the healthcare system due to a strong reduction in the funds allocated to the health sector. Consequently the management of the hospital operative theaters like operating rooms (OR) has become a priority aspect in the health administration. In this context we performed a literary review about experiences or projects of operating room management (ORM) carried out in Italy between 2007 and nowadays. We searched Medline database and we found 12 articles meeting the inclusion criteria. Only one paper was submitted in 2007, the remain were drafted in the following years. The italian regions represented are mostly of the north center area. The topics discussed are heterogeneous: ORM reorganizations in clinical hospitals, simulations of models aimed to resolve OR slots assignment, surgical waiting lists management, OR process analysis and ORM literary review. Overall the results show that interest and competence for the ORM are quickly increasing in Italy. In fact, because OR are the most expansive and the most productive areas of every hospitals, it’s of paramount relief to implement strategies in order to optimize OR quality and minimize the non-productive and unnecessary costs, especially in the current period of austerity measures and continuous cuts to public funds.

An Exploratory Study of Financial Performance in CEE Countries
Authors: Cristina Curea Stefania , Belascu Lucian , Barsan Ana-Maria 
Published: January 2020

Our research investigates the performance of companies from Central and Eastern European (CEE) countries in the period after the Global Financial Crisis of 2007-2009 with the aim of identifying the driving factors behind accounting- and market-based performance. We include in the analysis companies from various industries in CEE countries that are European Union members and we study their performance between 2008-2016 over the following areas of performance: liquidity, solvency and indebtedness, operational profitability, global performance (through Return on assets and Return on equity), returns available to shareholders and market-based performance (through price/book value and Tobin Q ratio). Employing the hierarchical and non-hierarchical k-means cluster analysis companies are segmented into various homogeneous groups using various financial performance indicators as variables, Euclidian distances and the Ward amalgamation method. Furthermore, the resulting clusters have been grouped according to the country of origin and industry. Our findings show that specific groups of companies in these countries share common attributes, as evidenced by their performance indicators, which do not seem to be entirely based on their countries of origin and industry. Moreover, our exploration of CEE companies’ performance dynamics after 2008 evidences the increased competition in all industries particularly after 2009, as well as businesses’ need to adjust their activities after the losses incurred during the crisis period, but these phenomena is present with different intensities depending on country of origin and industry. At the same, we note the enhancement of global performance through improvements in the operational performance instead of financial leverage and indebtedness, which is a sound business approach by CEE companies.

The Cost- Saving Role of Blockchain Technology As a Data Integrity Tool: E-health Scenario
Authors: Radjenovic Zarko 
Published: January 2020

The digital economy of health and its global proliferation have led to the use of health information systems in the daily health services delivery to patients. Consequently, there is a development of web-based electronic healthcare aimed at providing electronic health services in real-time. In this way, through the implementation of the concept of electronic health, there is an exchange of health information among all stakeholders of the health organization, all with the aim of monitoring the health status of patients, timely intervention and adequate allocation of medical resources. Processing and sharing a large amount of health data in real time, with the constant need to maintain a high level of interoperability and scalability of network infrastructure, requires the highest possible level of security in accessing data, in order to reduce the misuse of health data. By using blockchain technology, the risk of misusing health information, asymmetry of information and the risk of increasing transaction costs are reduced in a very short time. Blockchain is a robust mathematical algorithm that can provide maximum security of the transaction using cryptographic methods. This type of technology is based on a distributed database that contains encrypted data that can not be changed or disturbed. For this reason, the application of this technology as a data integration tool is increasingly reflected in the electronic business of health organizations - electronic healthcare. Blockchain technology is especially used in information-intensive electronic healthcare records and medical applications, which ultimately results in reduced costs of providing health services, especially when it comes to system maintenance and security costs, interoperability and data redundancy. According to above-mentioned cost-saving role of blockchain technology in processing, sharing and analyzing healthcare data, in this paper, there will be more to say about the positive economic impact of blockchain technology on electronic healthcare, especially in the case of Estonia. This European country is a pioneer in creating, implementing and using the e-Health concept as an integral part of health information system through its healthcare system, in order to increase efficiency of healthcare services.

Surgical Approaches for Primary Total Hip Arthroplasty from Charnley to Now
Authors: Aggarwal Vinay K. , Iorio Richard , Zuckerman Joseph D. , Long William J. 
Published: January 2020

» Total hip arthroplasty is one of the most successful surgical interventions of the last century, yet questions remain as to the best surgical approach to use in order to achieve an optimal result. The main approaches to access the hip joint, which will be reviewed in this article, have a long history in the orthopaedic literature.» The evidence behind the advantages and disadvantages of each approach also will be reviewed. In general, it can be said that the anterior approach affords the best early recovery as measured in the first 2 to 4 weeks after surgery. Lateral approaches have the lowest rates of dislocation. The posterior approach has the lowest rates of overall complications, and concerns regarding dislocation have been mitigated with the use of larger-diameter prosthetic femoral heads and advanced soft-tissue repair techniques.» In the end, the selection of approach for total hip arthroplasty should be based on surgeon experience and familiarity with the approach. The pros and cons of each approach seem to equalize by 6 weeks postoperatively. Overall, the reproducibility of the operation is a testament to its continued success.
Evaluation of Multicomponent Adsorption Kinetics for Carbon Dioxide Enhanced Gas Recovery from Tight Shales
Authors: Berawala Dhruvit Satishchandra , Andersen Pål Østebø 
Published: January 2020

SummaryOnly 3 to 10% of gas from tight shale is recovered economically through natural depletion, demonstrating a significant potential for enhanced shale-gas recovery (ESGR). Experimental studies have demonstrated that shale kerogen/organic matter has higher affinity for carbon dioxide (CO2) than methane (CH4), which opens possibilities for carbon storage and new production strategies.This paper presents a new multicomponent adsorption isotherm that is coupled with a flow model for the evaluation of injection/production scenarios. The isotherm is dependent on the assumption that different gas species compete to adsorb on a limited specific surface area. Rather than assuming a capacity of a fixed number of sites or moles, this finite surface area is filled with species taking different amounts of space per mole. The final form is a generalized multicomponent Langmuir isotherm. Experimental adsorption data for CO2 and CH4 on Marcellus Shale are matched with the proposed isotherm using relevant fitting parameters. The isotherm is first applied in static examples to calculate gas-in-place reserves, recovery factors (RFs), and enhanced gas-recovery (EGR) potential according to the contributions from free-gas and adsorbed-gas components. The isotherm is further coupled with a dynamic flow model with application to CO2/CH4 substitution for CO2-ESGR, assuming only a gas phase exists in the system. We study the feasibility and effectiveness of CO2 injection in tight shale formations in an injection/production setting representative of laboratory and field implementation and compare that with regular pressure depletion.The production scenario we consider is a 1D shale-core or matrix system first saturated with free and adsorbed CH4 gas with only the left-side (well) boundary open. During primary depletion, gas is produced from the shale to the well by advection and desorption. This process tends to give low recovery and is entirely dependent on the well pressure. Stopping production and then injecting CO2 into the shale leads to an increase in pressure, where CO2 is preferentially adsorbed over CH4. The injected CO2 displaces but also mixes with the in-situ CH4. Restarting production from the well then allows CH4 gas to be produced in the gas mixture. Diffusion allows the CO2 to travel farther into the matrix while keeping CH4 accessible to the well. Surface substitution further reduces the CO2 content and increases the CH4 content in the gas mixture that is produced to the well. A result of the isotherm and its application of Marcellus experimental data is that adsorption of CO2 with resulting desorption of CH4 will lead to a reduction in total pressure if the CO2 content in the gas composition is increased. That is in itself an important drive mechanism because the pressure gradient driving fluid flow is maintained (pressure buildup is avoided). This is because CO2 takes approximately 24 times less space per mole than CH4.
