About the Profile Constancy by Curved Teeth Cylindrical Gear’s Cutter Head
Authors: Máté Márton , Gyéresi Hunor 
Published: May 2018

Abstract
Cylindrical gears with Archimedean spiral toothline represent a result of recent research. Similarly to the Öerlikon type bevel gears this type of gears cannot be grinded. This fact leads to the necessity of achieving best possible surface roughness while cutting using a specific cutter head. The paper presents the geometric model of the grinding technology applied for the main relief faces of the cutters and analyses the problems regarding the precision of the edge profile, its dependence with the technological setting parameters and the profile variation after the re-sharpenings. It concludes that the classic method of ground grinding allows a restricted number of resharpenings.

Authors: Kutasi Nimród , Kenéz Lajos , Filep Emőd , Szöllösi István , Jakab Farkas László 
Published: May 2018

Abstract
The paper deals with the design of a new plasma diagnostic system consisting of a microcontroller based power supply for automatic control of the measurement using Langmuir probe, the communication interface of the power supply and the signal processing program.
The main motivation for the design of the automated plasma diagnostic system was given by our research in different methods of plasma nitriding of steels. During the nitriding process, it is important to achieve information about the plasma, which is the medium where the heat-treatment process is going on. The new diagnostic system is able to perform measurements during the nitriding process, thus we can analyze the plasma at different temperatures and gas mixtures. The obtained voltage-current curves are recorded and transmitted to the computer, where further signal processing is performed. The paper presents the design of the power supply, the measurement results and the developed signal processing software.

Authors: Lefkovits László , Lefkovits Szidónia , Vaida Mircea-Florin 
Published: May 2018

Abstract
In automated image processing the intensity inhomogeneity of MR images causes significant errors. In this work we analyze three algorithms with the purpose of intensity inhomogeneity correction. The well-known N3 algorithm is compared to two more recent approaches: a modified level set method, which is able to deal with intensity inhomogeneity and it is, as well, compared to an adaptation of the fuzzy c-means clustering with intensity inhomogeneity compensation techniques. We evaluate the outcomes of these three algorithms with quantitative performance measures. The measurements are done on the bias fields and on the segmented images. We consider normal brain images obtained from the Montreal Simulated Brain Database.
The Pannon Optimizier – A Linear Programming Solver for Research Purposes
Authors: Stágel Bálint , Tar Péter , Maros István 
Published: May 2018

Abstract
The simplex algorithm is one of the most widely used linear optimization algorithms. Although its history goes back to the 1950’s it is still an evergreen topic because it is usually the hidden computational engine behind other algorithms. Thus its performance heavily affects other optimization systems. The implementation of the simplex algorithm is not a trivial task. An efficient implementation uses very complex methods. Since most of the open-source systems can hardly be used for research purposes the development of a structured and well-documented system is relevant. In this talk we present our own state-of-the-art solver and our development experiences.
Religion and gender inequality: The status of women in the societies of world religions
Authors: Klingorová Kamila , Havlíček Tomáš 
Published: May 2018

Abstract
The status of women in society is very diverse worldwide. Among many important traits associated with the differentiation of gender inequality is religion, which itself must be regarded as a fluid concept with interpretations and practices ‘embedded’ and thus varying with respect to cultural and historical relations. Admitting the complexity of the issues, some religious norms and traditions can contribute to the formation of gender inequalities and to subordinate the role of women in society. Using an exploratory quantitative analysis, the influence of religiosity on gender inequality in social, economic and political spheres is examined. Three categories of states have emerged from the analysis: (a) states where the majority of inhabitants are without religious affiliation, which display the lowest levels of gender inequality; (b) Christian and Buddhist societies, with average levels of gender inequality; and (c) states with the highest levels of gender inequality across the observed variables, whose inhabitants adhere to Islam and Hinduism.
Regional differences in entrepreneurial perceptions and implications for the Romanian competitiveness policy
Authors: Nicolae Mariana , Ion Irina , Nicolae Elena 
Published: May 2018

Abstract
Understanding entrepreneurship as being spatially rooted transforms it in a regional and national competitiveness factor. Despite the increasing importance of the territorial dimension in supporting economic growth at policy and declarative levels, in practice, in Romania, the territorial structure and spatial organization of the economy contributes little to the national value added. In this context, we study regional differences in entrepreneurial initiative and perception and their possible impact on the national competitiveness strategy. We use primary data collected in three Romanian regions (Centre, North-East, Bucureşti-Ilfov) and conduct a statistical analysis of the data. The results indicate different comparative regional profiles. The regional differences in the intentions, motivations, barriers and limitation for entrepreneurship confirm the theoretical view that personal motivations of becoming an entrepreneur are determined by environmental conditions. We conclude that the regional differences should be taken into account in the elaboration of the competitiveness policy, corroborated with the results of other similar studies.

Authors: Shekerinov Natasha T , Jordanova Vesna Dimovska , Bogoev Milco 
Published: May 2018

Abstract
Aim. To present new opportunities, clinical implications and benefits of the available VEGF therapy as a treatment of macular edema, which is a result of venous vascular occlusions, diabetic macular edema in diabetic retinopathy and age-related macular degeneration.
Background. The pathophysiology of macular edema is complex and various processes are involved in its development. It is actually an abnormal retinal capillary permeability and a disorder in the blood retinal barrier, which only increases the vascular permeability. This causes an expansion of the extracellular spaces, which leads to fluid accumulation, which additionally leads to macular thickening and eventual vision loss.
Methods. The studies included 40 patients, of whom17 was diagnosed with macular edema in diabetic retinopathy and were treated with anti-VEGF therapy. Also, there were 11 patients diagnosed with wet form of AMD, and 12 cases diagnosed with macular edema secondary to vein occlusion. This retrospective study of 18 months monitored the effects of visual acuity on Snellen chart and the effects of macula anatomy using Optical Coherent tomography /OCT/. All patients received intravitreal injection of Bevacizumab /Avastin/ of 1.25mg /0.04ml/ and were evaluated monthly or every 4 to 8weeks. We monitored the potential ocular and systematic side effects in all our cases.
Results. In the first group which included patients with edema due to venous vascular occlusion improvement of visual acuity in 58.33% patients, 25.0% showed no change in visual acuity and 16.66% showed slight worsening of 0.029 and regression of CMT entirely to 393.22 after 4.6 intravitreal injections on average. In the second group there was no improvement of VA 0.172 and reducing central macular thickness for 218.34μm by 5.6 intravitreal applications. The third group, 17 patients with macular edema due to diabetic retinopathy had stabilization of visual acuity, i.e. slight improvement in 8 of them by 0.14; and, in 9 and improvement of 0.21 and regression CMT, an average of 174.3 μm.
Although it has been shown that benefit of intravitreal use of Bevacizumab and improvement of visual acuity has not been always change hand in hand with the reduction of macular edema, the need for this kind of treatment in certain cases are needed to maintain stable CMT and VA in such patients.
Conclusion. Over the last few years monoclonal antibodies have become a standard therapy in treatment of wet form of AMD. Switch on anti-VEGF drugs has shown significant results in clinical and visual out-comes in patients with changes of the macula as a result of other disease. In fact, they caused a revolution in the treatment of refractory macular edema.

Abstract
The primary goal of this study is to examine the role of culture - as one of the most enduring, vital and long-lived components of sustainable development, with multifarious potential continuously explored and capitalized by individuals, communities or institutions. All definitions of the phrase sustainable development include culture as a sine-qua-non element that is also inextricably connected and interdependent with the other three pillars: economic, social and environmental. In this context of cultural centres worldwide, Confucius Institutes represent a successful and efficient managerial model by capitalizing on the most important resource of an organization: human capital.
Electrochemical behavior and conductivity measurements of electropolymerized selenophene-based copolymers
Authors: Alakhras Fadi 
Published: May 2018

Abstract
Electrochemical copolymerization of selenophene and thiophene was performed at a constant electrode potential. The obtained homopolymer films and copolymers were studied and characterized with cyclic voltammetry and conductivity measurements, from which conductivity values around 13.35 S · cm-1 were determined. The influence of the applied electropolymerization potential and the monomer feed ratio of selenophene and thiophene on the copolymers properties was investigated. The obtained copolymers showed good stability of the redox activity in an acetonitrile-based electrolyte solution. At higher polymerization potentials and at higher concentrations of thiophene in the feed, more thiophene units were incorporated into the copolymer chain. The conductivities of the copolymers were between those of homopolymers, implying that oxidation of both monomers was possible and the copolymer chains might accordingly be composed of both selenophene and thiophene units.

Published: May 2018

Abstract
The hydrothermal synthesis of MCM-22 zeolite was carried out using silica, sodium aluminate and hexamethyleneimine, under static conditions at 150 °C for a period of 10 days, followed by washing with deionized water, drying overnight and calcination at 650 °C. The obtained material was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The XRD analysis evidenced that MCM-22 presented a well defined MWW structure. The FT-IR spectrum confirmed the efficiency of the hexamethyleneimine as an organic template used to direct the structure of the MCM-22 zeolite under static conditions. The SEM image indicated that the particles are spherical in shape, with a diameter of ca. 10 μm. The acid properties of the MCM-22 zeolite, as determined by n-buthylamine adsorption, were investigated in the temperature ranges of 105 to 300 °C and 300 to 525 °C, relative to medium and strong acid sites, respectively.

Published: May 2018

Abstract
Pure and aluminum doped zinc oxide nanoparticles were prepared by soft chemical method. The prepared nanoparticles were characterized by XRD, SEM-EDAX, UV-Vis, PL and FT-IR studies. XRD patterns revealed that the nanoparticles were crystallized in hexagonal wurtzite structure with an average particle size of 19 nm to 26 nm. The surface morphology was explored using SEM micrographs. The incorporation of aluminum was confirmed by EDAX and FT-IR studies. The band gaps of the particles were found from 3.48 eV to 3.53 eV through UV-Vis spectral studies. The defect related mechanism was investigated using PL measurements. The chemical functional groups in FT-IR spectra proved the formation of pure and aluminum doped zinc oxide nanoparticles.

Authors: Trzepiecinski Tomasz , Gromada Magdalena 
Published: May 2018

AbstractIn this paper, three BaTiO3 powders of various particle size distributions were obtained as a result of mechanical activation in the mixer mill. Green barium titanate pellets and cylindrical specimens were fabricated by both uniaxial and isostatic pressing methods. As a result of the application of different maximal sintering temperatures, the obtained materials were characterized by various average grain sizes: 0.8 μm, 20 μm and 31.0 μm. The basic properties of sintered pellets and cylinders were determined and the influence of materials average grain size on their Young’s modulus and compressive strength were determined through compression tests in a uniaxial testing machine, Zwick/Roell Z100. The elastic properties were similar for tested materials with a different grain size. However, the microstructure of BaTiO3 strongly influenced the compressive strength.

Published: May 2018

Abstract
Controllership, as an informational activity, is becoming a multidimensional function, about which numerous doubts exist as to whether to increase its independency and integrate it tightly with the decision-making process. Financial knowledge and business-analytical capabilities of carriers of controllership activity can offer support for operational, financial, and strategic restructuring. This is important when facing frequent business dynamics in order to enhance competitiveness and especially achieve short-term as well as strategic goals.
The Role of Accounting in a Society: Only a techn(olog)ical solution for the problem of economic measurement or also a tool of social ideology?
Authors: Horvat Robert , Korošec Bojana 
Published: May 2018

Abstract
The contribution juxtaposes the traditional neutralistic view on the role of accounting in a society as an activity of independent and unbiased measurement and presentation of real economic phenomena with the extended view on accounting as a socio-political practice and ideology. It also shows how the latter view impacts the understanding of the role of accounting and its reactions in light of the recent global financial crisis.
Fire Risk Analysis and Optimization of Fire Prevention Management for Green Building Design and High Rise Buildings: Hong Kong Experience
Authors: Yau Albert , Ho Samuel K. M. 
Published: May 2018

Abstract
There are many iconic high rise buildings in Hong Kong, for example, International Commercial Centre, International Financial Centre, etc. Fire safety issue in high rise buildings has been raised by local fire professionals in terms of occupant evacuation, means of fire-fighting by fire fighters, sprinkler systems to automatically put off fires in buildings, etc. Fire risk becomes an important issue in building fire safety because it relates to life safety of building occupants where they live and work in high rise buildings in Hong Kong. The aim of this research is to identify the fire risk for different types of high rise buildings in Hong Kong and to optimise the fire prevention management for those high rise buildings with higher level of fire risk and to validate the model and also to carry out the study of the conflict between the current fire safety building code and the current trend of green building design. Survey via the 7-point scale questionnaire was conducted through 50 participants and their responses were received and analysed via the statistical tool SPSS software computer program. A number of statistical methods of testing for significantly difference in samples were adopted to carry out the analysis of the data received. When the statistical analysis was completed, the results of the data analysis were validated by two Fire Safety Experts in this area of specialisation and also by quantitative fire risk analysis.
Reliability of B-Mode Ultrasound Imaging of the Lateral Abdominal Muscles in Healthy Children During the Active Straight Leg Raise Test
Authors: Linek Paweł , Saulicz E. , Wolny T. , Myśliwiec A. 
Published: May 2018

Abstract
Background: To date, reliability of ultrasound imaging (USI) measures of the abdominal muscles in children during the active straight leg raise (ASLR) test has not been confirmed. The aim of this study is to assess the intra-rater reliability of USI in measuring of the thickness and percent thickness change of the external oblique (EO), internal oblique (IO) and transversus abdominis (TrA) on both sides of the body during the ASLR test.
Material/Methods: Thirty-two healthy children between 10-12 years old participated in the study. Three repeated USI measurements were recorded, in supine and resting positions and during the ASLR test. In supine position, measurements were collected at the end of normal expiration. In the case of ASLR, measurements were collected when the person undergoing examination touched the transverse delimiter with the distal part of the lower leg. A repeat session of the measurements was carried out 6 to 8 days later.
Results: The use of mean value of the three repeated measurements showed that ICC3.3 fluctuated from 0.81 to 0.97 for OE, OI and TrA in resting position and during the ASLR test. In terms of percentage change of muscle thickness, the ICC3.3 result obtained for TrA, OE and IO were 0.86, 0.83 and 0.78, respectively.
Conclusions: The USI evaluation of the lateral abdominal muscles thickness at rest has high reliability in children between 10-12 years old. The USI of the actual thickness and reflex activity of OE, OI and TrA during the ASLR test, based on three repeated measurements, is also reliable. It is recommended to perform three repeated measurements for children between 10-12 years old. There is still a need to seek solutions that will decrease the SDD value while evaluating the reflex activity of the lateral abdominal muscles during the ASLR test.
The Use of Neuromuscular Electrical Stimulation of the Lower Limbs Skeletal Muscles in Cardiac Rehabilitation of Patients With Chronic Heart Failure
Authors: Kucio Ewa , Polak A. , Kucio C. 
Published: May 2018

Abstract
Research conducted in recent years suggests that neuromuscular electrical stimulation of the lower limb muscles (NMES) may be an alternative to physical training in patients with chronic heart failure (CHF). Through stimulating the work of the muscles, NMES raises the exercise tolerance, muscle mass and endurance in patients with CHF. A beneficial effect of NMES on muscle blood flow, aerobic enzymes activity, vascular endothelial function, decrease in pro-inflammatory cytokines and improvement of quality of life has been indicated. It must be emphasized that NMES procedures are comfortable for patients with CHF due to lower exercise load and therefore less intense symptoms of dyspnea. Moreover, these procedures may be conducted at home (after prior training). The possible side effects include temporary muscle soreness and skin impairment resulting from improper placement of electrodes (patients in ambulatory conditions).

Abstract
A number of research projects have shown that both religiousness and quality of the marital relationship are important resources that can be used by parents rearing children diagnosed with autism. Our article brings up the link between religiousness of parents who have children with autism and the quality of their marriage. Fifty-three married couples (106 persons) living in Poland and bringing up children diagnosed as having autism were surveyed. Results obtained indicate that there is a relationship between parents’ religiousness (personal religiousness) and their marriage quality. These results can help family therapists, social workers and priests supporting couples parenting children with autism.
