Published: January 2019

This study aims to describe the causes of high divorce rates in Muslim families in West Java based on the decisions of the Religious Courts, and this study also aims to formulate a strategy to prevent the increase in divorce rates. This study uses descriptive analysis method with interview techniques, study documents on the decisions of the Religious Courts and literature studies. The results of this study indicate that the highest cause of divorce in the mulism family in West Java is due to economic factors, there is no harmony and no responsibility. Prevention strategies for increasing divorce rates in West Java need to be done systemically from top to bottom, starting from family education before marriage and during conflicts between husband and wife. Thus, it can be concluded that the cause of the high divorce rate in Muslim families in West Java is due to a lack of commitment and knowledge of the essence of marriage, which makes the marital bond in a Muslim family fragile. The strategy to prevent increasing divorce rates is done systemically involving various elements, namely the government, community institutions, and the Religious Courts.

Published: January 2019

La caracterización y la abundancia de la macrofauna del suelo y su relación con la morfología del suelo, fueron evaluadas en áreas de fragmentos forestales de bosques secundarios en el Centro para la Biodiversidad y el Turismo del Amazonas, del Servicio Nacional de Aprendizaje - SENA, en Leticia, Amazonía colombiana. La macrofauna del suelo (invertebrados mayores o iguales a 2 mm de diámetro) fue evaluada en dos períodos estacionales (mayo y octubre) con diferentes registros de precipitaciones. Fue encontrado una abundancia total de 5332 individuos de la macrofauna del suelo, distribuidos en 14 órdenes taxonómicas. El fragmento forestal conservado (FFC) fue el área que registró una mayor diversidad florística, y presentó la mayor densidad de la macrofauna del suelo en ambos periodos de muestreo. Los grupos de insectos Isoptera y Formicidae, fueron predominantes, sobre todo, en el FFC. Las comunidades de macrofauna del suelo no detectaron correlaciones significativas con las variables de la morfología del suelo en los fragmentos forestales. Sin embargo, esa correlación se mostró significativa entre los dos periodos de muestreo, indicando que la estacionalidad de la pluviosidad puede afectar la densidad de la macrofauna del suelo dependiendo del periodo de muestreo.

Going the Full Circle: Upgrading the Patient Field Chart and Tag for Electronic Mass Casualty Incidents Solutions in Romania
Authors: Stănescu Adrian , Copotoiu Sanda Maria , Boeriu Cristian Marius
Published: January 2019

Objective: Mass casualty incidents and disasters require functional and efficient patient data management systems, as well as smart interconnections with patient tracking applications. Various initiatives developed and tested patient field charts for large-scale events but there is no one definite general format accepted. The current research proposes an upgraded model of the official patient field chart issued by the Romanian Department for Emergency Situations in 2015 to be used for large-scale events.

Measures: An upgraded model is created after a thorough content analysis, physical analysis, design upgrade and optimization process. Differences between the official and the upgraded model are measured and compared, and statistical computations are carried out.

Results: The main distinctive features of the patient field chart are dynamic triage, unique code identification, QR visual codes, wireless tags and irreversible clear contamination status highlighting. The upgrade process results in almost doubling the available active area without the need to change the document size format of the product. Visual elements and features are included to optimize operation workflow.

Conclusions: The upgraded model offers a variety of improvements for both the overall rescue effort as well as the end user of the product. It allows for previously unavailable features like unlimited dynamic triage and enables the use of electronic management solutions.
Uncommon Finding of a Gastrointestinal Stromal Tumor in a Patient with Hyperechoic Liver Lesions - Case Report
Authors: Roman Adina Maria , Dobru Daniela , Fofiu Crina , Boeriu Alina
Published: January 2019

Introduction: Hyperechoic liver lesions identified by conventional ultrasonography are diverse in underlying pathology and most of the time require further investigations. Gastrointestinal stromal tumors (GIST) are rare neoplasms of the gastrointestinal tract which are uncommonly found in metastatic stages at first presentation.

Case report: We present the case of a 51 years old woman with nonspecific symptoms in which conventional ultrasonography showed hyperechoic lesions in the right lobe of the liver with a diameter up to 40 mm. Esophagogastroduodenoscopy revealed a submucosal tumor on the small curvature of the stomach, on the anterior wall, with central ulceration, with normal narrow band imaging (NBI) mucosal pattern and negative gastric biopsy. Contrast enhanced ultrasonography was performed, describing multiple lesions with inhomogeneous enhancement in the arterial phase and rapid washout at the end of arterial phase. Endoscopic ultrasound with fine needle aspiration (EUS-FNA) biopsy examination was definitive for the final diagnosis of epithelioid gastric gastrointestinal stromal tumor. The patient was diagnosed with T2N0M1 epithelioid gastric GIST, stage IV, and is currently under treatment with tyrosine kinase inhibitors.

Conclusions: GIST represent a diagnostic challenge in medical practice because of its size, unusual location in the submucosal layer and lack of symptoms. The role of EUS-FNA is of paramount importance in increasing the accuracy of diagnosis in the case of GIST. The particularity in our case consists of the unusual presentation with the lack of specific symptoms and signs associated with the presence of metastatic lesions at the moment of the diagnosis of GIST.

Authors: Jančić-Rašović Sanja , Cristea Irina
Published: January 2019

This paper is a continuation of our work on hypernear-rings with a defect of distributivity D. In particular, here we introduce and study a new subclass of hypernear-rings, called D-division hypernear-rings, establishing a necessary and sufficient condition such that a hypernear-ring with the defect D is a D-division hypernear-ring. Several properties and examples of these two subclasses of hypernear-rings are presented and discussed.
Caterpillars Have Antimagic Orientations
Authors: Lozano Antoni
Published: January 2019

An antimagic labeling of a directed graph D with m arcs is a bijection from the set of arcs of D to {1, …, m} such that all oriented vertex sums of vertices in D are pairwise distinct, where the oriented vertex sum of a vertex u is the sum of labels of all arcs entering u minus the sum of labels of all arcs leaving u. Hefetz, Mütze, and Schwartz [3] conjectured that every connected graph admits an antimagic orientation, where an antimagic orientation of a graph G is an orientation of G which has an antimagic labeling. We use a constructive technique to prove that caterpillars, a well-known subclass of trees, have antimagic orientations.

Estimating clique size by coloring the nodes of auxiliary graphs
Authors: Szabó Sándor
Published: January 2019

It is a common practice to find upper bound for clique number via legal coloring of the nodes of the graph. We will point out that with a little extra work we may lower this bound. Applying this procedure to a suitably constructed auxiliary graph one may further improve the clique size estimate of the original graph.

Estimation of Power and Delay in CMOS Circuits using Leakage Control Transistor
Authors: Kumar Aylapogu Pramod , Aditya B.L.V.S.S , Sony G. , Prasanna Ch. , Satish A.
Published: January 2019

With a rapid growth in semiconductor Industry, complex applications are being implemented using small size chips, with the use of Complementary Metal Oxide Semi-Conductors (CMOS). With the introduction of new Integrated Circuit (IC) technology, the speed of the circuits has been increased by around 30%. But it was observed that for every two years, the power dissipation of a circuit doubles. The main reason for this power dissipation is leakage currents in the circuit. To reduce these leakage currents, we can reduce the width of the device. In addition to this, we can use lector techniques that use Leakage Control Transistors (LCT) and High Threshold Leakage Control Transistors (HTLCT).In this paper; we present a circuit technique that uses 130 nano-meter CMOS VLSI circuits that use two extra transistors to mitigate the leakage currents. The proposed technique overcomes the limitations posed by the existing methods for leakage reductions an average leakage reductions is 82.5%.The estimation of power and delay will be discussed using LCT’s and HTLCT’s.

Authors: Monori Fanny , Oniga Stefan
Published: January 2019

BCI (Brain-Computer Interface) is a technology which goal is to create and manage a connection between the human brain and a computer with the help of EEG signals. In the last decade consumer-grade BCI devices became available thus giving opportunity to develop BCI applications outside of clinical settings. In this paper we use a device called NeuroSky MindWave Mobile. We investigate what type of information can be deducted from the data acquired from this device, and we evaluate whether it can help us in BCI applications. Our methods of processing the data involves feature extraction methods, and neural networks. Specifically, we make experiments with finding patterns in the data by binary and multiclass classification. With these methods we could detect sharp changes in the signal such as blinking patterns, but we could not extract more complex information successfully.
The Support of Agricultural Land Through the “Central European Initiative on Agricultural Land Protection”
Authors: Palšová Lucia
Published: January 2019

The protection of the qualitative aspects of agricultural land is in the interests of both Slovakia and the European Union. Several policy documents have emerged in the European Union over the last few years, however, they have not been legally binding, as the EU Member States refuse all binding legal acts in this area. Therefore, solving the problem of agricultural land protection is left to the exclusive competence of the EU Member States. On the other hand, problems related to agricultural land cross the borders of states and that is why the Department of Law, Faculty of European Studies and Regional Development, Slovak University of Agriculture in Nitra submitted an international research project under the Erasmus + program, Key Action 3: Jean Monnet entitled “Central European Initiative on Agricultural Land Protection”. The aim is to strengthen the dialogue between key stakeholders in the protection of agricultural land in Central Europe what will have a positive impact on the achievement of the EU agri-environmental and food policy objectives.

Consumer Trust in E-Commerce: The Case of Poland
Authors: Rybak Anna
Published: January 2019

The increasing use of the Internet as a commercial sales channel arouses interest in understanding key issues in building customer relationships. Confidence is considered the key to the success of building these relationships. Considering the differences between online and offline sales, the antecedents and consequences of trust deserve a reconsideration. This research identifies satisfaction and knowledge as key factors related to trust in the context of online sales. The findings from this study suggest that people buy online more often if they see a higher level of trust in e-commerce and have more experience in using the web. Customer satisfaction can be influenced by the level of trust as well as the user’s experience and knowledge about the distribution channel as well as the e-seller. It seems that people with a higher level of satisfaction with shopping become loyal customers and more often participate in e-commerce. Positive experience and the ability to monitor purchases favors the development of the e-commerce market in Poland. These results complement earlier arrangements for e-commerce and shed light on how to establish a trust relationship on the World Wide Web.
Income Diversification in Low Income Sub-Saharan African Countries’ Commercial Banks: A “Blessing” or “Curse”?
Authors: Olarewaju Odunayo Magret
Published: January 2019

Dynamics in economic trend and banks’ creditors’ expectation have directed banks to search the innovative means of income generation. It is with this view that this study examines the relationship between the income diversification and financial performance of banks in SSA low income countries. A panel data of 1,280 observations were extracted from the financial profile of 160 commercial banks from 19 purposively selected countries from 2009 to 2016. The findings from the empirical analysis indicate that non-interest income accounts for 95% of operating income in Low Income countries’ commercial banking sector. Also, it was found that income diversification in SSA banks enhanced financial performance as affirmed by the finance theory because both interest and non-interest income sources are indeed blessings as they increase the financial performance significantly. Therefore, low income SSA countries’ commercial banks are urged to strive to ensure proper investment with their income diversification so that better performance of their economies is enhanced.

Authors: Ejupi Arsim
Published: January 2019

The aim of this paper is to analyze in chronological terms the idea for the construction of Morava-Vardar canal and the contemporary geopolitical consequences of this project along with its economic, environmental and social impacts. Through critical readings of different contributions and reports made by scientific community, other institutions and media we have presented the idea in chronological terms from the late years of the 19th century until recent years. Continental geographical position Serbs have, has always been considered as an obstacle for their overall development. Through participation in unsustainable geopolitical formations they have continuously managed to develop any kind of connections to the sea. Even though part of various political entities over the time the effort to reach the direct contact to the sea was not successful. For this reason, Serbs raised idea and developed a project to connect their continental state with the sea through construction of the Morava-Vardar water canal. Except economic and environmental consequences, construction of this canal would have geopolitical implications in Balkan Peninsula known as very unstable geopolitical region.

The main objective of this article was to analyse whether the Interactive Video Test (IVT) is a useful tool for the practical off-field training of soccer assistant referees, and if its use could reduce erroneous on-field decisions when applying Law 11 of the Laws of the Game. Assistant referees were taken from the Spanish 2nd “B” and 3rd Divisions, and were divided into two groups, the Experimental Group (EG) and the Control Group (CG). The referees in the EG were trained with the Interactive Video Test by analysing 720 off-side decisions. Subsequently, both groups were assessed in on-field tests involving the simulation of 326 possible off-side situations. When the results of both groups were compared, there was a continuous improvement over time in the EG associated to the use of the IVT, significantly better than the improvement of the CG. Moreover, the IVT proved to be a good diagnostic tool to assess the skills of assistant referees in perceiving and evaluating off-side situations.

Published: January 2019

Objectives. The aim of this paper is to compare the degree of accuracy between the BASDAI and mini-BASDAI indices in assessing the activity of ankylosing spondylitis (AS), especially in patients without peripheral manifestations.

Materials and method. Our cross-sectional study consisted of a group of 124 patients with AS, according to the modified New York criteria. All patients offered their informed consent. All the individual characteristics of the patients were documented, both demographic and disease-related. The activity of the disease was measured using the BASDAI questionnaire, from which we calculated the mini-BASDAI by eliminating the questions about peripheral arthritis and entesitis. The functional impairment of mobility in the spine and sacro-iliac joints was measured by the Schober index, lateral spinal flexion, occiput-wall, menton-sternum and finger-ground index.

Results. The mean age of the patients was 43.43 +/− 13.27 years, mean height 174.3 +/− 8.46 cm, weight 78.23 +/− 14.19 kg, duration of disease in years 15.06 +/− 9.19 and number of years from initiation of biological therapy 6.42 +/− 3.08. The BASDAI score was 1.26 +/− 1.93, while the mini-BASDAI score was 1.51 +/− 2.08. In the group of patients without peripheral manifestations, both BASDAI and mini-BASDAI correlated significantly with the occiput-wall index, besides ESR, CRP, ASDAS-CRP and the Schober index.

Conclusion. Mini-BASDAI is not superior to BASDAI in evaluating patients with ankylosing spondylitis without peripheral manifestations, but it has shown a better correlation in addition to BASDAI with the indices of flexion of the cervico-dorsal spine.
Development of Electronic Payments in Georgia
Authors: Mushkudiani Nino
Published: January 2019

Electronic payments are considered to be a fast and secure alternative for traditional payment methods. Today, it is impossible to imagine modern bank operations, commercial transactions and other payments without electronic payments. This article shows that electronic payments are not the only means for reducing costs with respect to other payment methods, such as cash, but can also generate significant benefits for increasing economic development and reducing shadow economy. The paper focuses on the development of electronic payments in Georgia and its impact on the economy of the country. Over the decades, the payment systems in Georgia have evolved significantly in line with the technological advancement. Significant progress has been achieved in improving the e-payment systems infrastructure. The evolution of e-payments in Georgia can be characterized by the following: debit (including prepaid) and credit cards, credit and debit transfers compose a core set of noncash payment types commonly used today by consumers and businesses. These core noncash payment types are used both in traditional ways, such as in-person purchases, payroll deposits, and bill payments, and in innovative ways, such as contactless and mobile payments, e-commerce and online bill payments. Using the economic-mathematical analyses of the information taken from the web-page of the National Bank of Georgia and commercial banks’ publications, a mathematical model was built, based on which the positive relationship between e-payments and economic growth in terms of real GDP was shown.

Authors: Vértesy Gábor , Tomáš Ivan
Published: January 2019

Influence of changing rate of magnetizing current in magnetic adaptive testing was studied. Sensitivity of magnetic descriptors, which characterize the samples degradation, was found to depend on this speed. Low speed results in a better sensitivity, but the effect depends on permeability of the investigated specimens. Recommendation was made for the optimal choice of the applied speed of the magnetizing current.

Objective

To evaluate the electroencephalographic (EEG) findings and correlate EEG findings with inflammatory biomarkers and the sepsis prognostic scores SOFA, SAPS II and APACHE II in patients who present in the Emergency Department with sepsis without clinical central nervous system involvement.

Methods

The study included seventeen patients (< 70 years old) with sepsis without central nervous system involvement presenting in the Emergency Department of the University Hospital of Patras, Greece. All patients underwent neurologic examination and EEG analysis on admission to the hospital and were treated according to the international guideline protocols for sepsis.

Results

Six of seventeen sepsis patients had mild or moderate EEG abnormalities. We did not find any significant correlation between EEG abnormalities and inflammatory biomarkers (CRP, WBC) or commonly used prognostic sepsis scores.

Conclusions

EEG could serve as a useful tool to identify brain alterations at an early stage in sepsis, before clinical sings of encephalopathy can be detected. However, the presence of EEG abnormalities does not correlate with sepsis severity as measured by the commonly used prognostic sepsis scores SOFA, APACHE II or SAPS II. Because this was a small single center observational study, large multi-center studies are warranted to confirm these findings.
