Antecedentes: La infección por el virus Zika se ha asociado con abortos y en los recién nacidos con un patrón de anomalías del desarrollo denominado síndrome del Zika congénito. El inicio del brote de Zika en el Ecuador coincidió con el terremoto en Pedernales aumentando su riesgo y vulnerabilidad. El objetivo de este estudio fue evaluar los Conocimientos, Actitudes y Prácticas de los jefes de familia con relación al Zika en el embarazo. Metodología: Se realizó un estudio observacional, exploratorio, descriptivo y transversal, mediante la aplicación de una encuesta sobre conocimientos, actitudes y prácticas en la enfermedad viral de Zika, a los habitantes (jefe de hogar) del área urbana de la ciudad de Pedernales. Fue realizada en septiembre 28 y 29 del 2016.
Resultados: Se encuestaron 60 jefes de familia. El 78,3 % de las personas encuestadas fueron mujeres. El 65% de jefes de familia encuestados no tenía empleo. El 83.3% de la población conoce que la enfermedad se puede dar por la picadura del mosquito. El 16.7% de encuestados conoce que la transmisión puede darse por vía sexual. En cinco mujeres embarazadas encontradas (8.3%), dos tuvieron síntomas sugestivos de Zika en el embarazo y ninguna se realizó pruebas diagnósticas para la enfermedad por Zika. El 38,3% de los encuestados opina que las mujeres que contraigan el virus de Zika durante el embarazo deberían tener acceso a servicios de aborto seguro y legal.
Discusión: El riesgo elevado frente al Zika resulta evidente debido a la condición post terremoto. Los conocimientos, actitudes y prácticas de Zika relacionados con el embarazo en Pedernales fueron inadecuados por lo que se debe fortalecer los conocimientos sobre mecanismos de transmisión del Zika principalmente de la vía sexual.

Authors: Podstawka Marian 
Published: October 2019

Summary

Subject and purpose of work: The subject of this study is transfer prices and their use for optimization of financial burdens of international companies (capital groups). The purpose of this study was to present transfer pricing issues in the light of applicable law and using them for tax purposes.

Materials and methods: The study uses literature and data from the World Bank and Google. Methods of descriptive and tabular analysis and inference were used.

Results: Google makes 91% of its revenues outside the US.

Conclusions: Transfer pricing is a tool for optimizing tax burden of international companies that bring them benefits in the form of the so-called “globalization annuity”, which makes them economically stronger and more technologically competitive. Polish tax law on transfer pricing has been tightened since 2001; transfer pricing issues are also regulated by the European Union and the Organization for Economic Cooperation and Development (OECD).
The Use of Municipal Bonds in Financing Regional Economic Development in Poland
Authors: Kozak Sylwester 
Published: October 2019

Summary

Subject and purpose of work: The article presents an analysis of the use of municipal bonds in financing the development activities of local governments in Poland.

Materials and methods: The study uses data from the Ministry of Finance, the European Central Bank, the Central Statistical Office and the CATALYST platform.

Results: The results of the research show that the level of using bonds by local governments in Poland is lower than the EU average. Poland’s accession to the EU and the inflow of structural funds significantly increased local governments’ interest in the implementation of bonds to fund investments, especially in 2008-2010.

Conclusions: A significant part of funds from the issues of municipal bonds was allocated to regional development projects, mainly infrastructure. In 2008-2012 the value of newly issued municipal bonds increased, however, after that the number and value of new issues significantly decreased.
An Econometric Analysis of the Effects of Human Resources and other Factors on Firm Creation
Authors: Zlatković Matea 
Published: October 2019

Abstract
Intangible assets and knowledge are key drivers of today’s economy, called knowledge economy, as a consequence of globalisation process and information and communication technology development. Knowledge and intellectual capital became leading factors that provide basis for gaining superior performance and sustainable competitive advantage of firms in dynamic and uncertain business environments. Invisible goods based on knowledge are becoming more important in generating and successful managing businesses. The purpose of this research is to test the impact of human resources on creation of the firm or, in other words, to examine individual’s inclination toward becoming an entrepreneur in transition economy such as Bosnia and Herzegovina. While investigating the relationship between human resources and firm creation, additional social, economic and emotional factors are included in analysis. Proposed theoretical model is tested using logistic regression model to analyse a sample of 2.015 individuals in Bosnia and Herzegovina, as a participant in GEM project in 2014. Obtained results show that the amount of individual’s knowledge, skills and expertise and its capability to seek and recognize new entrepreneurial opportunities, considered as human resources owned by individual, increase probability to generate a firm in Bosnia and Herzegovina. Beside human resources, certain economic and social factors, such as work status and social perception of entrepreneurship as an attractive profession, are important for firm creation in Bosnia and Herzegovina.

Published: October 2019

Abstract
Recently, with the advancement of techniques, endoscopic ultrasound-guided therapies have shown distinct advantages, especially in relieving benign and malignant gastric outlet obstruction (GOO), as well as in postoperative pancreaticobiliary diseases. Herein, we present five currently used approaches in endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumenapposing biflanged metal stents (LAMS), along with several examples of LAMS-based EUS treatment of pancreaticobiliary diseases. Compared with traditional treatment methods, EUS-guided procedures have – to some degree – shown higher success rates, both technical and clinical. Moreover, EUS-guided therapies reduce the risk of multiple surgical adverse events, including delayed gastric emptying, prolonged hospital stay, increased costs, and delay in cancer treatment. Particularly in terms of postoperative pancreaticobiliary diseases, EUS-guided therapy has assumed an essential role as a treatment option in cases where traditional methods are difficult to perform. Nevertheless, EUS-guided gastrointestinal procedures are still relatively new, with some clinical failures, and additional prospective clinical trials are warranted.

Published: October 2019

Abstract

Background: Campylobacter infections are typically self-limited, but in cases with severe enteritis, immuno-compromised system and bacteremia, an appropriate antimicrobial treatment is demanding. Our study aim was to determine the isolation rate of Campylobacter among patients with acute enteritis in the capital of North Macedonia and its antimicrobial susceptibility.

Material and methods: A total number of 3820 patients clinically diagnosed as acute enteritis, were included in the study. Stool samples were collected and Campylobacter was isolated and identified by classical microbiological methods. Antimicrobial susceptibility of all isolates to Ceftriaxone, Amoxicillin-clavulonic acid, Erythromycin, Ciprofloxacin, Tetracycline and Gentamicin was determined by disc-diffusion technique. Additionally, minimal inhibitory concentrations of all Campylobacter isolates against erythromycin, ciprofloxacin and tetracycline were determined by Epsilon gradient tests.

Results: Campylobacter species was isolated in 97 patients. Although the mean isolation rate of Campylobacter spp. during the whole study period was 2.53%, a statistically significant increase was detected in 2016 and 2017, in comparison with the data from previous four years of the study. The isolation rate of Campylobacter spp. didn’t reveal statistically significant difference between males and females (p > 0.05). 46.4 % of patients with Campylobacter enteritis were children at the age under 15 years. Forty-three C. jejuni isolates were susceptible to all six antibiotics, but the remaining 44 isolates revealed resistance to at least one antibiotic. C. coli isolates were resistant to 3 antibiotics simultaneously. Two C. coli isolates only, were susceptible to all 6 antibiotics. 40.90% of C. jejuni and 50% of C. coli isolates were resistant to beta-lactams, fluoroquinolones and tetracyclines, simultaneously.

Conclusion: The increase of the isolation rate of Campylobacter from patients with acute enteritis indicates the need for permanent isolation and identification of Campylobacter from every clinically diagnosed patient, as acute enteritis. Erythromicin is the most effective antibiotic for treatment of Campylobacter enteritis in our patients. The high level of Campylobacter resistance to beta-lactams, fluoroquinolones and tetracyclines requires more rational approach in the treatment of Campylobacter enteritis

Abstract
Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a preventable cause of in-hospital death, and one of the most prevalent vascular diseases. There is a lack of knowledge with regards to contemporary presentation, management, and outcomes of patients with VTE. Many clinically important subgroups (including the elderly, those with recent bleeding, renal insufficiency, disseminated malignancy or pregnant patients) have been under-represented in randomized clinical trials. We still need information from real life data (as example RIETE). The paper presents case series with VTE in special conditions, including cancer associated thrombosis, malignant homeopathies, as well in high risk population.
Dwellings for Vulnerable Households-Policy and Practice in the Largest Cities of Poland
Authors: Załęczna Magdalena 
Published: October 2019

Abstract
In Poland municipalities do not fulfil their statutory obligations of providing dwellings for vulnerable households and often limit their activity to merely providing housing for persons to whom the court has granted the right to dwelling in eviction proceedings. However, even for these people there are not enough dwellings. This very difficult situation of Polish municipalities in terms of the provision of direct housing assistance results from history-related problems with the quality of the existing housing stock, a lack of reform of municipal lease rules and insufficient financial resources. The author focused on a comparison of the municipal housing stock management in the largest cities in the context of changes that took place in years 2009-2016. The results of the research proved there were important differences among cities in terms of the activity of applying the available instruments. Despite acting in the same institutional framework, some municipalities were able to improve the housing situation of citizens most in need of assistance, step by step. The survey covered the voivodeship capital cities of Poland. Critical analysis of literature and documents as well as an analysis of statistical data were used.
Perception Effects of High Voltage Transmission (HVT) Lines on Residential Property Values: Cases of Chalala, Libala South and Kamwala South Areas of Lusaka City-Zambia
Authors: Jain Niraj , Chileshe Roy A. , Muwowo Francis M , Mwewa Mambwe 
Published: October 2019

Abstract
Although several recent studies have shown how high voltage transmission (HVT) lines affect property values, no work has been undertaken in Zambia. This paper explores if there is a prima facie relationship between HVT lines and residential property values in Zambia. A priori evidence shows a paradox, with many new developments springing up in areas of high concentrations of HVT lines though residents vehemently complain about the mal-effects of HVT lines. Why then should land perceived to be inferior or “stigmatized” attract new developments? It is against this background that the householders’ perceptions of HVT lines are explored and the resulting effects on property values ascertained. A household survey was conducted in the Chalala, Libala South and Kamwala South areas of Lusaka city where developments have been undertaken around HVT Lines. The study also examined the statistical relationship of distances from HVT line with residential property values. Results show residential property values rise with increasing distance from the HVT line. It is recommended that the statutory wayleave distances should be raised to at-least 100 meters from the existing 31 meters for a 132kV line. It is further recommended that the regional wayleave guidelines currently in use should be made national.
Application of Mathematical Modelling for Optimization of Land-Use Management
Authors: Taratula Ruslana , Kovalyshyn Oleksandra , Ryzhok Zoriana , Malakhova Svitlana 
Published: October 2019

Abstract
The work has approved the methods of partial economic evaluation of lands by the indicators of yield capacity of agricultural crops, payback of expenditures and differential income for a typical agricultural enterprise, located on the territory of the natural-agricultural province of the Western Forest-steppe. The research supplies proposals concerning improvement of the methods of economic evaluation of lands in Ukraine on the example of the indicators of economic evaluation of the land use at the farming enterprise “GREEN GARDEN”. The indicators are used for the growing of agricultural crops, planning their yield capacity, comparison of the economic fertility of soils and determination of the economic results of growing agricultural crops under the current production conditions in a defined working area.
The research proposes the optimization of land-use management, applying a metrical game on the basis of indicators of the economic evaluation of lands to define the optimal share of agricultural crops in crop rotation. This method can be used to optimize land use in any region. Application of mathematical modeling by indicators of differential income ensures that maximum gross income is obtained under the mixed strategy of the game on better and worse soils in the enterprise.
Dissimilarity as a Component of the Property Price Model
Authors: Zyga Jacek 
Published: October 2019

Abstract
In the course of discussion on an econometric model of property value and its place in property appraisal, the argument of the main goal of the process (property market value prediction itself) was raised in this article. The need for the consideration of an ontologically perceived, particular element of the real estate market with its distinctive characteristics indicates the specific nature of the interpretation of the data which may be used in the appraisal process.
Therefore, a new shape of the property value model, based on LSM, was presented. It takes into account a specific description of the appraised property. Thus, the factor of dissimilarity between sold properties used in creating the value model and the appraised property was used in its coefficient matrix. The new model clearly shows the advantages and disadvantages of the dissimilarities between sold properties used in creating the coefficient matrix of the value model.

Xor-Magic Graphs
Authors: Siehler Jacob A. 
Published: October 2019

Abstract
A connected graph on 2n vertices is defined to be xor-magic if the vertices can be labeled with distinct n-bit binary numbers in such a way that the label at each vertex is equal to the bitwise xor of the labels on the adjacent vertices. We show that there is at least one 3-regular xor-magic graph on 2n vertices for every n ⩾ 2. We classify the 3-regular xor-magic graphs on 8 and 16 vertices, and give multiple examples of 3-regular xor-magic graphs on 32 vertices, including the well-known Dyck graph.
Soil types specified in the bonitation classification and their analogues in the sixth edition of the Polish Soil Classification
Authors: Smreczak Bożena , Łachacz Andrzej 
Published: October 2019

Abstract
The aim of the paper was to present the correlation between soil types specified in the sixth edition of the Polish Soil Classification (SGP6 2019) and Polish bonitation classification. The comparisons included two categories of agricultural land: arable soils and soils of permanent grasslands. In Poland bonitation maps are one of the oldest documentations regarding soil cover. They were elaborated in an uniform manner and based on the field examination of soil profiles. Soil information reflected specific rules adopted in the soil quality classification, including identification of soil types based on genetic criteria and recognition of appropriate sequence of specific horizons in the soil profile. Publication of the sixth edition of the Polish Soil Classification enabled the attempt to adjust soil units (soil types) specified in both systems. Despite the distinction of new soil units in the Soil Classification of Poland (SGP6 2019), the usage of bonitation maps and classification protocols should not pose major difficulties in reinterpretation of soil types. This indicates on the possibility to introduce, similarly to year 2012, the terminology adapted to the requirements of modern soil science knowledge without causing significant changes in the soil-valuation table.
