Dueños y poseedores de la naturaleza: la relación artificial-natural en la Dióptrica de Descartes
Authors: García Rodríguez Sergio 
Published: October 2018

RESUMENLa interpretación actual de la ciencia cartesiana ya no concibe ésta como una mera deducción desde los principios metafísicos, sino que reivindica el papel de la experiencia en ella. El presente artículo tratará de dar un paso más, defendiendo que existe una dimensión instrumental en la ciencia cartesiana. Para ello, se analizará la modificación que Descartes realiza en la Dióptrica de la relación artificial-natural y que posibilita una lectura instrumentalista.PALABRAS CLAVEDESCARTES, ARTIFICIAL, NATURAL, INSTRUMENTALISMO, CIENCIAABSTRACTThe current interpretation of the Cartesian science no longer sees it as a mere deduction from the metaphysical principles, but claims the role of experience in it. This paper will try to go one step further, arguing that there is an instrumental dimension in the Cartesian science. With this purpose in mind, we will analyze the modification performed by Descartes in the Dioptrics regarding the artifitial-natural relation, which enables this instrumentalist reading.KEYWORDS DESCARTES, ARTIFICIAL, NATURAL, INSTRUMENTALISM, SCIENCE

Published: October 2018

Abstract

Objective: Our article was prepared to outline how Humen Resource Managememnt developed in Hungary and Slovakia. We considered it was important to highlight in light of empirical data on the most important features of this development in both countries.

Methodology: Our research is based on the Cranet international research questionnaire. The survey was carried out in Hungary and Slovakia in 2015 and 2016. More than five hundred (527) organizations took part in the survey, and the findings of the report are based on normal statistical methods (mean, frequency, distribution). Our analysis was carried out with the help of SPSS software

Findings: In Hungary and Slovakia, the ongoing economic transformation has produced significant changes in the practice of Human Resource Management (HRM) in both institutions and enterprises and its evaluation. The organization has become an increasingly important factor in the strategic significance of the function itself and of HR departments in general, and this survey details the personnel or human resources (HR) management policies and practices of organizations or enterprises in both the public and private sectors.

Value Added: We believe that through our article we are able to expose the similar and different characteristics of HRM in the two countries examined.

Recommendations: We believe that the similarities and differences between countries are not only to be reviewed in traditional areas, as in language, culture or economic development, it is worth looking at areas such as similarities and differences of HRM.
Applying the Anticipatory Failure Determination at a Very Early Stage of a System’S Development: Overview and Case Study
Authors: Chybowski Leszek , Gawdzińska Katarzyna , Souchkov Valeri 
Published: October 2018

Abstract
Anticipatory Failure Determination (AFD) is a tool used in the TRIZ (Theory of Inventive Problem Solving) methodology. This article introduces its concept and describes the process of AFD in different versions of the method. The article presents the application of the AFD method at a very early state of a system’s development, i.e. its concept formulation stage, which corresponds to a technology readiness level (TRL) equal to 2. The system under analysis is a set of devices used to reduce displacement ship hull resistance. The system was modelled using functional analysis. An analysis of system resources was then carried out. Possible direct, indirect, and accident-related failures were identified. A multi-criteria analysis of the causes of system failures was conducted from which the top 10 potential failures were selected. Observations were made on the applicability of AFD in respect to systems not yet implemented.

Published: October 2018

Abstract
The combination of Creative Dance and BrainDance within the context of physical education could be a promising innovation. This combined program can be implemented in primary school to help students achieve a better and more holistic assessment of their Health-Related Quality of Life (HRQoL), covering aspects of physical, emotional, social, and mental functioning and well-being. The aim of this study was to investigate the impact that a combined Creative Dance and BrainDance program based on the Laban Theory of Movement Analysis has on HRQoL perceptions of primary school students when this program is implemented within the context of the physical education curriculum in primary school. For this purpose, an eight-week educational intervention was designed combining Creative Dance and BrainDance into one single program. The survey sample consisted of 32 fifth- and sixth-grade primary school students. The Kidscreen-52 questionnaire was used to collect data. Data analysis was performed with the use of descriptive statistical indices and mixed analysis of variance (ANOVA). Although the results showed no differences between the beginning and end of the educational intervention, a fact that might be due to the small sample and the time of the implementation of the program (limited to 8 weeks), its implementation produced very good results with regard to improvisation, body control, balance, and coordination, as well as kinaesthetic awareness and musical rhythmic skills. Creative Dance and BrainDance promote imagination, creativity, improvisation, and self-esteem in general, particularly in primary school students..

Abstract

Introduction. The development of mass media, including an Internet has a significant impact on the lifestyle of young people. Despite of universal access and countless opportunities offered via Internet, an increasingly common phenomenon observed for several years is the excessive use of networks by young people, which can lead to Internet addiction.

Aim. The aim of this study was to determine the degree of the Internet addiction in a group of junior high school students and high school students and selected conditions of this state.

Material and methods. The applied research method was a diagnostic survey, and the following tools: the Kimberly Young’s Internet Addiction Test and the authors’ self-designed survey. The study covered 263 junior high school and high school students. The research was carried out from April to June 2018.

Results. The Internet addiction was observed in 11% of the surveyed students. The use of social networking sites was the most common reason for using the Internet among surveyed (95%). The health problems associated with the long time of using the network of addicted students were general fatigue (61%) and lack of sleep (61%). Students addicted to the Internet much more often felt lonely (61%), depressed, upset or sad (n = 22, 78.6%) in contrast to other respondents.

Conclusions. Demographic variables (such as: sex, type of school, place of residence) have no significant impact on the development of Internet addiction. Psychosocial functioning has an impact on the development of the Internet addiction.

Published: October 2018

Abstract

Aim. The aim of the study was to determine the state of knowledge of women using health services on the midwife’s tasks in the primary health care.

Material and methods. The research was conducted online in the period from February to March 2018 among women receiving health services in primary health care. The study was attended by 200 respondents aged 18-60 – they were informed about the voluntariness, anonymity of participation in research and the use of results only for scientific purposes. The diagnostic survey method was used for the research using the author’s questionnaire.

Results. Most of the respondents knew their family physician (87.5%) and only half of the respondents knew their midwife (50%). The midwife was mainly associated with childbirth and neonatal care. In the minds of women, the midwife can conduct education (72%), but most of them only knew about the possibility of counseling in the field of pregnancy, postpartum period, early motherhood.

Conclusions. 1. Women receiving healthcare services have incomplete knowledge of who their physician, midwife and nurse are in primary health care. 2. In the consciousness of women, there is the idea that midwives (including midwives of primary health care) deal only with pregnant women and after childbirth, but they do not know that midwives are involved in education regarding the prevention of gynecological diseases. 3. In reference to the low level of public knowledge about primary health care midwife’s competence, it is necessary to conduct activities aimed at promoting the midwife profession and raising public awareness in this area.

Published: October 2018

Abstract
The course of epoxidation of sesame oil (SO) with performic acid formed „in situ” by the reaction of 30 wt% hydrogen peroxide and formic acid in the presence of sulfuric acid(VI) as a catalyst was studied. The most advantageous of the technological independent parameters of epoxidation are as follows: temperature 80°C, H2O2/ C=C 3.5:1, HCOOH/C=C 0.8:1, amount of catalyst as H2SO4/(H2O2+HCOOH) 1 wt%, stirring speed at least 700 rpm, reaction time 6 h. The iodine number (IN), epoxy number (EN), a relative conversion to oxirane (RCO) and oxirane oxygen content (EOe) were determined every hour during the reaction. Under optimal conditions the sesame oil conversion amounted to 90.7%, the selectivity of transformation to epoxidized sesame oil was equal to 93.2%, EN = 0.34 mol/100 g, IN = 0.04 mol/100 g oil (10.2 g/100 g oil), a relative conversion to oxirane RCO = 84.6%, and oxirane oxygen content of EOe = 5.5%.

Published: October 2018

Abstract
The purpose of this article is to describe the methodology to define coefficient of friction between a tool and a forming material during tube cold draw technology process. In this regard, an experimental drawing process was done by using the tensile testing machine. The tensile testing machine was modified by additional equipment that allows drawing the tube. During the drawing, the force was recorded. Subsequently, the finite element simulation of cold draw forming was used to generate load-stroke curves with different friction coefficient. The friction coefficient was estimated by comparing the load stroke and the force recorded curves.

Authors: Görög Augustín , Görögová Ingrid 
Published: October 2018

Abstract
In practice, pipe products are often produced. The surfaces of these components are often turned. The three-jaw chuck is often used to clamp the components for turning. It is a universal clamping fixture. The main advantage of three-jaw chuck is its high flexibility. However, its disadvantage is the inappropriate influence of the clamping forces on the geometrical accuracy of the produced components. This article deals with research of the influence of clamping forces on the roundness of turned pipes. A universal three-jaw chuck was used. The chuck was tightened using a torque wrench. The applied tighten torques were determined by monitoring the commonly used torques for a manually tightened chuck. The article presents the results of experimental research.

Published: October 2018

Abstract
The system with short circuiting metal transfer in comparison to common MIG/MAG process was introduced as CMT (Cold Metal Transfer) process by the Fronius company in 2004. The paper deals with the arc current analysis of the CMT process during MIG brazing of automotive components. The TPS 5000 CMT power source together with VR 7000 CMT wire feeder, Robacta Drive CMT welding torch and CuAl 5 Ni 2, Ø1 mm filler metal were used. In order to monitor the welding current, the galvanic separator WS 1.0, digital oscilloscope ETC M621 and IBM notebook with software applications ETC Scope M621 were engaged. A current waveform in the stage D at the time of 5s from the brazing process beginning within duration of 50 ms was closely analysed. The analysis revealed the total ratio of the arc burning to the total brazing time to be approximately 26%. The starting and ending phases of short-circuit were performed at decreased current (approximately 34 to 38 % of the current value during arc burning), which was very positive from the transient effect point of view, and could not be proclaimed for the conventional short-circuit droplet transfer modes.

Application of GFRP Reinforcement in the Design of Concrete Structures and its Experimental Evaluation
Authors: Gajdošová Katarína , Borzovič Viktor , Valašík Adrián , Gažovičová Natália 
Published: October 2018

Abstract
In the past, research on the use of FRP in civil engineering has been focused on strengthening existing structures where FRP reinforcements were applied to the surface of concrete elements. Recently, the application of FRP reinforcements has been studied to replace steel reinforcements for use in areas of increased environmental loads, with a need to exclude the corrosion of the reinforcement or to ensure the electromagnetic neutrality of the individual elements of the load-bearing structure. The GFRP reinforcement ratio was verified considering failure modes in flexure and the bond of the GFRP reinforcement with concrete. Besides classical reinforcements, GFRP has also been used in prestressed variants, and the possibility of its use as permanent formwork has been verified. In terms of extending the use of non-metallic reinforcements, it is important to note the long-term exposure and possible degradation of the mechanical properties.

РАДИОНУКЛИДЫ 226Ra, 232Th, 40К, 137Cs В ПОЧВАХ НА ЗВОНЦОВЫХ И ЛЕНТОЧНЫХ ГЛИНАХ
Authors: Мингареева Е.В. , Апарин Б.Ф. , Сухачева Е.Ю. 
Published: October 2018

Представлены и проанализированы данные о содержании естественных радионуклидов (ЕРН) 226Ra,232Th, 40K и техногенного 137Cs в почвах Северо-Запада России. Почвенные образцы были отобраны в различные временные периоды: до первых ядерных испытаний (1926 и 1932 гг.), в период интенсивных ядерных испытаний (1964 г.) и после их запрета (1996, 2000 и 2009 гг.). Использование коллекции Центрального музея почвоведения им. В.В. Докучаева позволило впервые определить удельную активность (RA) ЕРН до первых ядерных испытаний в естественных почвах, сформированных в относительно одинаковых природно-климатических условиях лесной зоны на озерно-ледниковых отложениях – звонцовых и ленточных глинах. Выявлено, что RA ЕРН в почвах на звонцовых глинах варьирует в более широком диапазоне, чем в почвах на ленточных глинах. Почвы на звонцовых глинах по средним значениям RA в сравнении с почвами на ленточных глинах содержат больше 226Ra и меньше 232Th и 40K, что, возможно, связано с особенностями поведения радия-226 в почвах. Отмечено, что содержание ЕРН в почвообразующих породах варьирует в более узких диапазонах по сравнению с верхней частью профиля. Выявлена взаимосвязь удельной активности радионуклидов с величиной рН и гранулометрическим составом почв. Техногенный 137Cs обнаружен только в современных образцах почв. Его содержание варьирует в пределах 6,7–48,6 Бк/кг (М = 17,5 ± 17,0 Бк/кг). Наиболее высокая RA цезия-137 отмечена в почве на ленточных глинах Ленинградской области. В образцах почв на звонцовых глинах Новгородской и Псковской областей его содержание низкое (˂10 Бк/кг). Существенная разница в RA137Cs в почвах исследуемых регионов, вероятно, вызвана особенностями распространения радиационного загрязнения после аварии на ЧАЭС. Коллекция почвенных монолитов и материалы исследования физико-химических свойств и удельной активности радионуклидов в почвах, отобранных в период с 1926 по 2009 г., может стать основой для организации почвенно-экологического мониторинга в Северо-Западном регионе Европейской территории России.

Introdução: As Doenças Cardiovasculares (DCV) constituem a principal causa de morbidade e mortalidade nos países desenvolvidos e em desenvolvimento, alcançando cerca de 30% das mortes nas últimas décadas. A inatividade física é um dos fatores de risco para que a DCV ocorra com maior frequência. Objetivo: Verificar o nível de atividade física prévia em indivíduos que sofreram Síndromes Coronarianas Agudas (SCA). Metodologia: Estudo prospectivo, descritivo e de análise quantitativa dos dados, desenvolvido em um Hospital de Ensino da cidade de São Paulo, com 33 pacientes admitidos no Pronto Socorro com diagnóstico médico de SCA. Para a verificação do nível de atividade física foi utilizado o International Physical Activity Questionnaire, IPAQ-versão longa, composto por 27 questões sobre atividade física no trabalho, no transporte, em casa e lazer. Resultados: Em todas as categorias de classificação do IPAQ prevaleceram os sedentários. No trabalho, eram sedentários 42,4% dos pacientes, seguido por indivíduos ativos (30,3%) e muito ativos (27,3%). No transporte, o sedentarismo (45,5%) foi seguido por indivíduos ativos (33,3%), e irregularmente ativos (21,2%). Em casa, sedentários (39,4%), irregularmente ativos (33,3%), ativos (21,2%) e muito ativos (6,1%). No lazer ocorreu a maior frequência de pacientes sedentários (78,8%), seguido pelos ativos (12,1%) e pelos irregularmente ativos (9,1%). Conclusão: Ao verificar o nível de atividade física prévia em indivíduos que sofreram SCA foi possível verificar que em todas as categorias de classificação do IPAQ prevaleceram os sedentários.
