Penelitian ini bertujuan untuk menentukan nilai resistivitas lapisan tanah kemudian mengkaitkan dengan kelayakan pembangunan gedung bertingkat pada daerah pesisir pantai Kahona Kabupaten Tapanuli Tengah. Berdasarkan analisa nilai resistivitasnya penelitian ini menggunakan Metode Geolistrik Konfigurasi Schlumberger. Variasi nilai tahanan jenis akan diperoleh jika jarak masing-masing elektroda diubah, kemudian diperoleh nilai tahanan jenis yang bukan nilai sebenarnya tetapi berupa tahanan jenis semu. Data yang diperoleh menggunakan alat Geolistrik ARES-G4 v4.7 SN: 0609135 berupa nilai resistivitas semu, kemudian diubah menjadi nilai resistivitas. Data yang diperoleh dibuat menjadi gambar model penampang dua dimensi dengan menggunakan software Res2Dinv. Hasil penelitian menunjukkan bahwa daerah pesisir pantai Kahona memiliki nilai resistivitas yang masih rendah sekitar 4,84 Ωm sampai 105 Ωm pada lintasan pertama dan 0,865 Ωm sampai 165 Ωm pada lintasan kedua. Berdasarkan dari nilai resistivitas yang diperoleh, daerah tersebut mengandung liat/lempung pada kedalaman 1,25 – 28,7 meter. Berdasarkan hasil penelitian ini daerah pesisir pantai Kahona belum dapat direkomendasikan untuk pembangunan gedung bertingkat karena tidak terdapat lapisan keras pada struktur batuan bawah permukaan tanah. Pengukuran nilai resistivitas setiap lintasan memiliki persentasi kesalahan 23,6 – 24,2 %.Kata Kunci : Geolistrik, Konfigurasi Schlumberger, Lapisan Keras.

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.

Published: January 2019

Abstract

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.

Published: January 2019

Abstract

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.

Published: January 2019

Abstract
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

Abstract
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.

The reciprocal distance signless Laplacian (briefly RDSL) matrix of a connected graph G is defined as RQ(G)= diag(Tr′ (G)) + RD(G), where RD(G) is the Harary matrix (reciprocal distance matrix) of G and diag(Tr′ (G)) is the diagonal matrix of the vertex reciprocal transmissions in G. In this paper, we investigate the RDSL spectrum of some classes of graphs that are arisen from graph operations such as cartesian product, extended double cover product and InduBala product. We introduce minimum covering reciprocal distance signless Laplacian matrix (or briey MCRDSL matrix) of G as the square matrix of order n, RQC(G) := (qi;j),

where C is a minimum vertex cover set of G. MCRDSL energy of a graph G is defined as sum of eigenvalues of RQC. Extremal graphs with respect to MCRDSL energy of graph are characterized. We also obtain some bounds on MCRDSL energy of a graph and MCRDSL spectral radius of 𝒢, which is the largest eigenvalue of the matrix RQC (G) of graphs.

Published: January 2019

Abstract
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

Abstract
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

Abstract
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.

Furthermore, the conducted research proved that the participation of employees in trainings has a fundamental impact on their professional development path.
Consumer Trust in E-Commerce: The Case of Poland
Authors: Rybak Anna 
Published: January 2019

Abstract
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

Abstract
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.

Published: January 2019

Abstract
The comparative studies of the tarsal joint capsule of cattle (Bos taurus) and canines (Canis lupus) have clarified general patterns of the structural organization of a joint capsule and the species-specific features of its angioarchitectonics. The differences in the formation of the fibroelastic layer and the location of vascular fields in the cases of animals with different stances were established. The zones of intensive intraorganic vascularization of the joint capsule were revealed; that being—the plantar and dorsal surface in the case of cattle, the lateral and medial surfaces—in case of the canine.

Published: January 2019

Abstract
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.

Published: January 2019

Abstract
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.
Comparative Analysis Between the Basdai and Mini-Basdai Indices in Patients with Ankylosing Spondylitis
Authors: Burtica Sandra , Gurghean Adriana , Bruckner Ion 
Published: January 2019

Abstract

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.
