Authors: Dziuba Szymon T. , Ingaldi Manuela , Zhuravskaya Marina 
Published: May 2020

Abstract
Job satisfaction has a big impact on how an employee performs his job. Both elements have an impact on job safety and employee perception of it. A satisfied employee devotes himself to work, performs orders better, cares for others and for himself. He feels safe in the enterprise. The aim of the paper was to assess employees' job satisfaction and their work performance with use of simply survey. In order to achieve this aim, a survey was conducted among employees of a chosen metallurgical enterprise who were asked to assess level of their job satisfaction. The employees defined their job satisfaction by referring to 20 statements describing this satisfaction and evaluating three factors that were used to compute the satisfaction index. The survey allowed for indication the general level of employee satisfaction.

Analysis of Road Safety in the Context of Horizontal Visibility Within Intersections – Field Studies
Authors: Brycht Natalia 
Published: May 2020

Abstract
One of the important factors on which road safety depends is adequate visibility. This article analyses horizontal visibility within road intersections. The visibility condition depends on many factors, primarily on the geometric parameters of road elements and the location of buildings, fences, vegetation etc., neighboring the road. The aim of the research presented in the study was to determine the current condition of horizontal visibility, on the example of twenty two intersections located mostly in built-up rural area along a provincial road near Czestochowa. The research was carried out by two methods (the analysis of satellite photographs and the visual method) and the obtained results were compared. The assessment of the security level was based on applicable regulations and technical guidelines. It was found that the results of the visibility assessment based only on the analysis of maps and satellite photographs are in many cases overestimated, due to the fact that many small elements not visible in the photographs are not taken into account and the occurrence of convex vertical road arches within the field of visibility. However, the main reason for the insufficient visibility at the many intersections is the fact that the geometrical parameters of roads and their surroundings were shaped in the past when the traffic conditions were completely different. It was also noted that road managers perceive this problem and take measures to increase safety within road intersections.

Published: May 2020

Abstract
The paper deals with the working peculiarities of the support zones of reinforced concrete elements subject to bending with due account of the eccentric compression and tension. The authors performed simulation of the stress-strain behaviour of the indicated structures with the aid of “Lira” software which results are shown in the graphical and tabulated form. The performed simulation allowed of tracing the work of the studied sample beams till collapse. Such approach made it possible to single out and generalize the main collapse patterns of the inclined cross-sections of the reinforced concrete elements subject to bending on which basis the authors developed the improved method to calculate their strength (Karpiuk et al., 2019).
Influence of Public Financial Support on the Process of Roof Covering Replacement and Safety of Civil Structures
Authors: Ulewicz Małgorzata , Liszewski Wiesław 
Published: May 2020

Abstract
This article constitutes an analysis of the influence of public financial support on the process of replacement of the asbestos-cement sheets used as a roof covering for materials safe for the environment. Commonly used asbestos-cement sheets, known under the commercial name of „Eternit”, should be removed of civil structures by 2032 following a program established by the Polish state. However, the carried-out analysis indicates that until present times the products containing asbestos have been properly identified in all municipalities across Poland, and also the amount of financial support that a property owner may obtain for removal of products containing asbestos is relatively low comparing to the costs of the roofing replacement. The cost of roof covering replacement falls within the range. 18.417 – 41.232 PLN/m2, so for the roof area of 100 m2 and considering the simplest roof structure (gable roof) the cost would total between 18.417 and 41.232 PLN. Therefore the existing system of public financial support providing funds for asbestos removal only will not affect the investor’s decision regarding replacement of roof covering and increase of civil structures safety. The replacement process of dangerous Eternit roof covering is slow and most probably the established programmed will not be completed on time.
Repeatability and Reproducibility Studies for Non-Replicable Tests
Authors: Mikulová Pavlína , Plura Jiří , Knop Krzysztof 
Published: May 2020

Abstract
The paper presents several approaches to gauge repeatability and reproducibility (GRR) analysis regarding non-replicable measurements. Measurement systems have to deal with processes in which, by the nature of the measured object or by the type of measurement itself, measurements are not repeatable. In these cases, each sample unit can be measured only once. Such situations are referred as nonreplicable measurement systems. The aim of the paper is to map out the current approaches being used in GRR analysis in various cases of non-replicable tests and compare each other in order to find out the suitable use of analysis application. Approaches used are subject to critical analysis so that its review can serve a useful base for analysis of different non-replicable tests. At present, it is desirable to bring the improving actions in order to obtain the results of high quality from such kind of measurements. Since different non-replicable tests can measure a different quality characteristic, it is valuable to bring the appropriate designs for various tests. Subsequently, this review will serve an outline how to proceed in analyzing the results obtained by non-replicable tests. Specifically, GRR analysis works with two known designs named as “Crossed” and “Nested” design, which statistical software normally use. Doubtfully, crossed design is suggested to use at certain cases and nested at other specific cases. This is assessed and improving actions designed.

Published: May 2020

Abstract
The analysis of product quality is an indispensable action in developing enterprises. In case of mechanical products, the non-destructive tests (NDT) are effective way to make control. Non-destructive tests allow making assessing product quality without destroying it. Due to the dynamically growing requirements of customers and necessary, the improvement actions for demanding organizations important is to make a complex analysis of quality products. Such an action was proposed to a production and service company located in Podkarpacie region of Poland. The aim was to analyze the quality of the mechanical lever and improvement the process of non-destructive tests, in order to identify the source of nonconformity with using quality management techniques. These activities were to demonstrate that the sequence (NDT and selected quality management techniques) would allow the detection of unconformities on the product surface and also identify the source of this unconformity. In the enterprise, the quality research of the product using fluorescent and magnetic-powder methods was made. After identified the unconformity on the product the additional actions which could point the source of unconformity were not practicing. The proposition of improvement in the NTD was use appropriately selected quality management techniques (Ishikawa diagram and 5Why method) after identified the unconformity. The mechanical lever was tested, which its surface using the magnetic-powder method was analyzed. After identified unconformity (scratch) using the Ishikawa diagram, the potential causes were identified and four main causes were selected (i.e.: uncleaned pattern, impurities during production, poor molding mass, poorly carried out product production method). It has been shown that sequence of NDT, Ishikawa diagram and 5Why method allows to identify the unconformity on product surface and source its creation. This sequence could be practicing to analyze other product in production and services enterprises.

Efficiency of Corn and Poplar Biomass Saccharification after Pretreatment with Potassium Hydroxide
Authors: Dąbkowska-Susfał Katarzyna 
Published: May 2020

Abstract
Pretreatment is an essential step in the conversion of lignocellulosic biomass into valuable products. It aims to increase the biomass susceptibility to enzymatic saccharification to generate fermentable monosaccharides. In this study, the efficiency of 2 % potassium hydroxide (KOH) solution used as a pretreating agent for various lignocellulosic feedstocks, such as corn straw, corncob, and poplar wood, was evaluated. The influence of the pretreatment time, which varied from 0.5 to 24 h at 50 °C, on the alteration of biomass composition was investigated, as well as the enzymatic digestibility. Finally, the overall sugar yields were determined. For corncob, the yield on average amounted to 453.9 ±18.9 mg·g−1 raw (untreated) biomass, regardless of the pretreatment time. The overall sugar yield for both the corn straw and poplar wood biomass increased with increased pretreatment time and ranged from 333.0 to 438.4 mg·g−1 raw biomass and from 123.2 to 215.7 mg·g−1 raw biomass, respectively. Based on the results obtained, the most appropriate pretreatment times for all types of biomass were proposed. The results of this study may be useful for the development of lignocellulosic biomass processing technology.

Published: May 2020

Abstract

Objectives. Psychoactive drugs are group of compounds used to treat severe mental problems, including psychosis, as well as other conditions. This study assessed clinically relevant side effects of haloperidol and clozapine on the thyroid hormones.

Methods. Haloperidol (0.05 and 2 mg/kg) or clozapine (0.5 and 20 mg/kg) was intraperitoneally injected to male Wistar rats for 28 days. The control group received 2 ml of physiological saline. A chemiluminescent immunoassay was used to measure the plasma levels of thyroid hormones.

Results. Plasma concentrations of thyroxine (T4) in rats treated with high-dose (2 mg/kg) of haloperidol decreased significantly compared to the control group (p=0.001). However, both low (0.5 mg/kg) and high clozapine (20 mg/kg) doses did not have a significant effect on the plasma concentrations of T4 and triiodothyronine (T3) (p>0.05). Neither of the compound had a significant effect on T3 plasma concentration levels (p>0.05).

Conclusions. Haloperidol and clozapine act via different mechanisms and may have dissociable effects on thyroid hormones. Following treatment with haloperidol, significant changes in T4, but not in T3, serum levels were observed. Haloperidol and clozapine had different effects on the thyroid hormone levels. These results indicate that antipsychotic treatment can contribute to the thyroid dysfunction. Therefore, greater caution should be applied to the antipsychotics use. The thyroid function of the patients should be closely monitored, while using these drugs.
Effect of amisulpride, olanzapine, quetiapine, and aripiprazole single administration on c-Fos expression in vasopressinergic and oxytocinergic neurons of the rat hypothalamic supraoptic nucleus
Authors: Kiss Alexander , Osacka Jana 
Published: May 2020

Abstract

Objective. The goal of this study was to reveal the impact of four types of atypical antipsychotics including amisulpride (AMI), olanzapine (OLA), quetiapine (QUE), and aripiprazole (ARI), with different receptor-affinity profile and dissociation constant, on the activity of hypothalamic supraoptic nucleus (SON) vasopressinergic and oxytocinergic neurons.

Methods. Male Sprague Dawley rats received a single injection of vehicle (VEH) (0.1 ml/100g), AMI (20 mg/kg), OLA (5 mg/kg), QUE (15 mg/kg/) or ARI (10 mg/kg). Ninety min after treatment, the animals were fixed by transcardial perfusion, the brains removed, and cryocut into serial coronal sections of 35 µm thickness. The sections were processed for c-Fos staining using an avidin-biotin-peroxidase complex and visualized by nickel intensified diaminobenzidine to reach black end product. Afterwards, the sections were exposed to vasopressin (AVP) and oxytocin (OXY) antibodies and the reaction product visualized by biotin-labeled fluorescent Alexa Fluor 568 dye. The data were evaluated from c-Fos and AVP or OXY merged sections.

Results. The present study shows that all four antipsychotics applied induced c-Fos expression in the SON. With respect to the stimulation efficacy of the individual antipsychotics, estimated based on the quantity of c-Fos-labeled AVP and OXY neurons, could be a preferential action assigned to QUE over moderate effect of ARI and lower effect to OLA and reduced effect of AMI (VEH < AMI < OLA < ARI < QUE).

Conclusion. The present data for the first time provide an insight into the quantitative pattern of brain activity within the clusters of SON AVP and OXY cells in response to different atypical antipsychotics single treatment.
The altered circadian pattern of basal insulin requirements – an early marker of autoimmune polyendocrine syndromes in type 1 diabetes mellitus
Authors: Pallayova Maria , Breznoscakova Dagmar 
Published: May 2020

Abstract

Objectives. The purpose of the present paper is to propose and introduce novel biomarkers of autoimmune polyendocrine syndromes that are relevant to the early diagnosis and optimal medical management of the patients who already suffer from type 1 diabetes mellitus.

Methods. We hypothesize and demonstrate on a case study that various organ-specific autoimmune endocrinopathies can result in lowered basal insulin requirements, leading to unexplained hypoglycemia.

Results. It can be hypothesized that hypothyroidism in patients with type 1 diabetes mellitus may deteriorate glycemic control and can lead to an increased rate of hypoglycemia, particularly the overnight and morning hypoglycemia. Thus, the decreased requirements for particularly overnight basal insulin can be an early marker of the autoimmune polyendocrine syndrome-3 with subclinical autoimmune thyroiditis in immune-mediated type 1 diabetes mellitus. Further, it could be proposed that unexplained hypoglycemia during the late afternoon or evening could be an early marker of the autoimmune polyendocrine syndrome-2 with subclinical autoimmune Addison disease in immune-mediated type 1 diabetes mellitus. As a result, an altered circadian pattern of basal insulin requirements can occur, characterized by a decreased late afternoon basal insulin rate.

Conclusions. After exclusion of other causes, the unexplained reoccurring hypoglycemia can be a remarkable feature of autoimmune polyendocrine syndromes in immune-mediated type 1 diabetes mellitus on intensive insulin replacement therapy.

Abstract

Objectives. Fibromatosis is a rare tumor with a prevalence of 2–4 per million per year. Its occur-rence in the thyroid is very rare and to the best of our knowledge only five cases have been reported in the literature.

Subject and Results. In this case report, we present a thirty-seven-year-old man without any significant past medical history, who presented with an anterior neck swelling and occasional cough for four months before admission. Sonographic-guided fine needle aspiration cytology studies reported a follicular neoplasm. Microscopic and immunohistochemical evaluation of the thyroidectomy specimen showed thyroid fibromatosis. The patient had no symptoms after surgery and no signs of recurrence after 2 years of follow-up.
Comparative Analysis of Retirement Benefits in Private Pension Funds and Public Pension System
Authors: Luković Stevan , Marinković Srđan 
Published: May 2020

Abstract
This paper identifies the conditions under which the private pension funds generate superior retirement outcomes compared to public pension system. The research objective is to determine the probability of success of the selected investment strategies in achieving the public pension system replacement rate, and the probability of the realization of extremely unfavourable outcomes. The methodology used in this paper includes the comparative analysis of simulated financial results of the four selected investment strategies implemented in the private pension fund model and the defined retirement benefits generated within the public pension system. For the simulation of the financial results at retirement, Monte Carlo simulation technique has been used. The authors have found that the success rate of the private pension fund in achieving superior financial results in comparison to public pension system is high, but only for the contribution rates higher than 10%. At low contributions rates, the extremely aggressive strategy is the only one that generates moderate success rate. Also, the probability of realization of extremely unfavourable financial results is lowest for the conservative strategy, which suggests that for the relatively high levels of the contribution rate, it is the most appropriate option for the pension fund members.
The Contribution of Monetary Policy to Mitigating the Consequences of the World Economic Crisis in Poland
Authors: Vujanić Vlado , Gligorić Dragan , Žarković Nikola 
Published: May 2020

Abstract
The economic authorities of each country seek to maintain the expansion phase through the implementation of various economic policy measures, namely, to prevent or mitigate the recessionary phase in economic development. In that context, it is of considerable importance to understand how monetary policy decisions affect the movement of macroeconomic variables. The paper aims to examine and evaluate the contribution of monetary policy to mitigating the effects of the global economic and financial crisis, using the Autoregressive Distributed Lag model, by analysing the impact of the real exchange rate, reference interest rate and money supply on the level of economic activity in Poland. Econometric analysis encompasses the period from 2006 to 2017. The research results suggest that there is a significant relationship between real economic activity and the real exchange rate both in the short and long term, but not between the reference interest rate and the money supply.

Career Anchors of Secondary School Teachers
Authors: Milanović Sandra 
Published: May 2020

Abstract
Career anchors represent the internal constellations of motives, needs and career goals of individuals. It is of great importance to identify person’s career anchor and according to it, to design career management practices. Furthermore, if there is congruence between career anchor and job related characteristics, many positive outcomes such as job satisfaction, organizational commitment, low turnover intentions, etc. may emerge. The aim of this paper is to identify which one of nine defined career anchors is dominant career anchor of secondary school teachers as public sector employees and how they differ in terms of demographic factors such as gender, age and work experience. In order to achieve this goal, empirical research was conducted using a sample of 44 secondary school teachers from one town. The descriptive statistic’s results indicated that the dominant career anchor of secondary school teachers is security – job tenure, followed by service and lifestyle career anchors. Non-parametric tests were applied for the assessment of statistically significant differences between demographic groups. Female teachers and teachers between 41 and 50 years expressed higher levels of importance of security – job tenure career anchor, but teachers with work experience lesser than 15 years showed higher levels of importance of security – geographic. The findings of this study add new contribution to the literature and career management practices in Serbia.
