Authors: Costa Flávia Mesquita , Costa Cassiano Lino dos Santos , Silva Juliana Batista , Ferreira Soraya Maria Zandim Maciel Dias
Published: April 2019

Fludeoxyglucose F 18 ([18F]FDG) is the most used radiopharmaceutical for positron emission tomography, especially on oncology. Organic solvents such as ether, ethanol and acetonitrile might be used in the synthesis of [18F]FDG; however, they might not be completely removed during purification steps. The determination of residual solvents in [18F]FDG is required in the European Pharmacopoeia (EP) and the United States Pharmacopeia (USP) monographs. While the procedure described in the EP is quite general, the one described in the USP requires a long runtime (about 13 minutes). In this work a simple and fast (4-minute) analytical procedure was developed and validated for determination of residual solvents in [18F]FDG. Analyses were carried out by gas chromatography – flame ionization detector (GC-FID). The separation was obtained on a 0.53-mm x 30 m fused-silica column. Validation included the evaluation of various parameters, such as: specificity, linearity and range, limits of detection and quantitation, precision (repeatability and intermediate precision), accuracy, and robustness. Results were found to be within acceptable limits, indicating the developed procedure is suitable for its intended application. Considering the short half-life of fluorine-18 (109.7 minutes), this new method could be a valuable alternative for routine quality control of [18F]FDG.

Published: April 2019

Thorium is a naturally occurring radioactive element that is widely distributed in the crust of the Earth. This element is very common in mineral formations in regions with high levels of natural radioactivity, therefore, its determination in environmental samples is important. Thorium isotopes (228Th, 230Th, and 232Th) were determined in a reference material, the IAEA Soil 327 sample, to validate the two methods, these isotopes were also analyzed in two groups of food samples, employing these different resins. The initial preparation with acid dissolution is the same to both, in the first is used anion exchange resin (DOWEX 1x2) and electrodeposition in silver planchets. And in the second method is used a specific chromatographic resin (TEVA) and cerium fluoride microprecipitation. At the end both analysis are quantified by alpha spectrometry. The two methods the results obtained were satisfactory for the reference material used, with relative error of less than 4% for 228Th, 230Th, and 232Th. The analysis of variance for samples foods analyzed seen to be no significant difference between the methods used for thorium isotopes determination. The main differences found between methods were spectrums resolutions, time and cost of analysis.

Published: April 2019

The literature presents many methods for partitioning of data set, and is difficult choose which is the most suitable, since the various combinations of methods based on different measures of dissimilarity can lead to different patterns of grouping and false interpretations. Nevertheless, little effort has been expended in evaluating these methods empirically using an archaeological data set. In this way, the objective of this work is make a comparative study of the different cluster analysis methods and identify which is the most appropriate. For this, the study was carried out using a data set of 45 samples of ceramic fragments, analyzed by instrumental neutron activation analysis (INAA). The methods used for this study were: Single linkage, Complete linkage, Average linkage, Centroid and Ward. The validation was done using the cophenetic correlation coefficient and comparing these values the average linkage method obtained better results. A script of the statistical program R with some functions was created to obtain the cophenetic correlation. By means of these values was possible to choose the most appropriate method to be used in the data set.

Authors: Da Costa Evaldo Luiz Correa , Gomes Joana D'Arc Ramos Lopes , Gomes Rogério Dos Santos , Costa Mara Lucia De Lara , Thomé Filho Zieli Dutra
Published: April 2019

This study gives an overview of the activities of the National Commission of Nuclear Energy (CNEN), as the Brazilian nuclear regulatory authority. These activities are described, especially those related to management of orphan sources and radioactive material in scrap metal considering the actions already put into place by CNEN during the licensing and controlling of radioactive sources in the industry and other facilities. In Brazil, there is not yet an effective system for controlling the scrap metal and recycling industry, thus a coordinated approach to achieve a harmonized and effective response with the involvement of third parties is needed, especially the metal industries and ores facilities. These practices call for stringent regulatory control, in order to reduce the occurrence of orphan sources, and consequently, radioactive material appearing in scrap metal. Some challenges of managing the national radiation sources register systems will be discussed, in order to cover effectively all the radiation source history (in a ‘from the cradle to the grave’ basis), and the dynamic maintenance and update of these data. The main industrial applications considered in this work are those dealing with constant movement of sources all over the country, with geographical issues to be considered in the managing and controlling actions, such as gammagraphy and well-logging.  This study aims to identify and promote good practices to prevent inadvertent diversion of radioactive material, taking into account existing international recommendations and some lessons learned in national level.
Antioxidant activity of Dianthus chinensis flowers processed by ionizing radiation
Authors: Koike Amanda Cristina Ramos
Published: April 2019

The edible flowers are increasingly used in culinary preparations, which require new approaches to improve their conservation and safety. Irradiation treatment is safe and an effective alternative for food conservation. Indeed, it can also guarantee food quality, increasing shelf-life and disinfestation of it. This technology gives us a versatile way to get good quality food, reducing post-harvest losses. Dianthus chinensis flowers, popularly known as Chinese pink, are widely used in culinary preparations, being also acknowledged for their bioactive components and antioxidant properties. The purpose of this study was to evaluate the antioxidant activity of D. chinensis flowers submitted to electron beam and gamma irradiation at 0, 0.5, 0.8 and 1 kGy. The antioxidant properties were evaluated through 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity, reducing power and β-carotene bleaching inhibition assays. Total phenolics were also determined by the Folin-Ciocalteu assay. The antioxidant activity was higher for irradiated samples, especially those treated with 0.8 and 1 kGy, independently of the radiation source, which showed the highest capacity to inhibit β-carotene bleaching. Accordingly, the applied irradiation treatments seemed to represent feasible technology to preserve the quality of edible flower petals, being able to improve the antioxidant activity
FLOW CYTOMETRY BASED MICRONUCLEUS ASSAY FOR EVALUATION OF GENOTOXIC POTENTIAL OF 2-ACBs IN HEPATIC CELLS HepG2
Authors: Barbezan Angélica Bueno
Published: April 2019

Food irradiation is approved for use in more than 60 countries for applications and purposes in a wide variety of foods, being an effective and safe method for preservation and long-term storage. 2-Alkylcyclobutanones (2-ACBs) are the only known radiolytic products generated from foods that contain fatty acids (Triglycerides) when irradiated. The acids analyzed in this study are palmitic and stearic, which when irradiated form 2-Dodecylcyclobutanones (2-dDCB) and 2-Tetradecylcyclobutanone (2-tDCB). Part of the 2-ACBs ingested is excreted through feces and part is deposited in adipose tissues. In vitro studies so far have been only in colon cells. The work used a human hepatoma cell line (HepG2) since the accumulation of fat in this organ is quite common. Micronucleus test was selected to evaluate possible genotoxic effects of 2-dDCB and 2-tDCB compounds when exposed to high concentrations (447, 1422 and 2235 μM) for 4 and 24 hours. Tests were performed in quadriplicates using flow cytometric analysis. None detectable genotoxic damage was observed after 4 hours of exposure to the compounds, and cytotoxic effects were only significant at the highest concentration (2235 μM) of 2-dDCB. After 24 hours of exposure, slight genotoxic damage was observed at all concentrations evaluated, and cytotoxic effects were only present when exposed to compound 2-tDCB. Although there is a genotoxic and cytotoxic effect in some of the situations tested, the two compounds predominantly induced proliferation reduction effects of this hepatic tumor cell line.

Published: April 2019

The increase in anthropogenic activities has been contributing to considerable increasing of the chemical elements concentration in the environment. One consequence is the need of monitoring the elemental composition of food available for consumption. Numerous techniques have been used to detect inorganic elements in biological and environmental matrices, always aiming reaching lower detection limits in order to evaluate the trace element content in the sample. This study evaluated the presence of inorganic elements in whole food samples, mainly elements on trace levels applying the neutron activation technique, k0-method. This method produces accurate and precise results, without the need of chemical preparation of the samples. For this purpose, four samples of different types of whole foods were irradiated in the TRIGA MARK I IPR-R1 research reactor – located at CDTN/CNEN, in Belo Horizonte, MG, Brazil. It was possible to detect, in total, twenty-three elements. Nine elements are considered essentials, according to nutrition literature, thirteen are not essentials and one, classified as contaminant element by legislation. The majority of the elements determined are not reported in the TACO (Brazilian Table for Food Composition). It means that the professionals of health do not know, in fact, the real chemical elemental composition in foods and the population do not know what they are ingesting in terms of chemical elements and the risks of this ingestion. This study reaffirms the INAA, k0–method, is an efficient technique for detecting trace elements in food samples.

Published: April 2019

This paper describes the Monte Carlo simulation, using MCNP4C, of a multichannel third generation tomography system containing a two radioactive sources 192I (316.5 – 468 KeV) and 137Cs (662 KeV), and a set of fifteen NaI(Tl) detectors, with dimensions of 1 inch diameter and  2 inches thick, in fan beam geometry, positioned diametrically opposite. Each detector moves 10 steps of 0,24o, totalizing 150 virtual detectors per projection, and then the system rotate 2 degrees. The Monte Carlo simulation was performed to evaluate the viability of this configuration. For this, a multiphase phantom containing polymethyl methacralate (PMMA ((r @ 1.19 g/cm3)), iron (r @ 7.874 g/cm3), aluminum (r @ 2.6989 g/cm3) and air (r @ 1.20479E-03 g/cm3) was simulated. The simulated number of histories was 1.1E+09 per projection and the tally used were the F8, which gives the pulse height of each detector. The data obtained by the simulation was used to reconstruct the simulated phantom using the statistical iterative Maximum Likelihood Estimation Method Technique (ML-EM) algorithm. Each detector provides a gamma spectrum of the sources, and a pulse height analyzer (PHA) of 10% on the 316.5 KeV and 662 KeV photopeaks was performed. This technique provides two reconstructed images of the simulated phantom. The reconstructed images provided high spatial resolution, and it is supposed that the temporal resolution (spending time for one complete revolution) is about 2.5 hours.

Published: April 2019

The present research proposal aimed to measure absorbed dose in a thorax phantom with synthetic breasts provided by an Intensity-Modulate Radiation Therapy (IMRT) protocol in an arbitrary RT center. As methods, a thorax simulator was prepared by the Ionizing Radiation Research Group (NRI) and radiochromic films were used for dose measurements. Tomographic images were taken at NRI phantom. Expositions were procedure in the Elektra 6MV LINAC. Hypofractionated regime was considered with a dose fraction of 2,7Gy in 16 fractions at the prescribed dose of 43.2 Gy at 95% of PTV. The dose comparison from the treatment planning system (TPS), Xio (Elekta) and from the experimental data was performed. The internal two-dimensional dose maps in the breast, at the skin on the left and contra-lateral breasts, heart and lungs. The measurements showed that the internal mean doses taken at the synthetic breast presented mean dose above the prescribed dose. Moreover, in general, doses to organs at risk (OARs) were within the Memorial Sloan Kettering Cancer Center (MSKCC) criteria. The non-full reproduction of the build-up region in the films had occurred due to the assymetrical positioning of the films in the inner breast, in the addition to their non-constant distance from the skin. Hot regions were present, may be due to the beam angulation chosen and the increase of MUs in the IMRT plane. As conclusions, the films can supply details and information that TPS does not provide. Assertiveness in clinical IMRT protocols can improve the prognosis and effectiveness of breast cancer treatment bring-ing possible clinical benefits.

Published: April 2019

Purpose: The purpose of this study is to determine the physical activity efficacy and physical activity of the middle school students, according to gender and to analyze the relationship between them. Material: The study group consisted of a total of 701 students from three public secondary schools, 343 of whom were female and 358 were male students. In order to determine the physical activity efficacy of the students, the Physical Activity Efficacy Scale was used, while the Physical Activity Questionnaire for Older Children was used for establishing the level of physical activity. In evaluating the data, descriptive statistics, independent t-test, Pearson correlation tests were used as statistical methods. Results: According to the data obtained by the study, the students’ physical activity efficacy was found to be good, with no difference between the females and the males (p>0.05). The students’ physical activity level was average, while the males were found to be physically more active than the females (p<0.05). A positive correlation was found between the physical activity efficacy and the physical activity of the students (p<0.05). Conclusion: According to the findings of this study, physical activities should be increased during the time of the middle school, which is a part of the period of adolescence. Besides, in order to enhance their physical activity efficacy, the adolescents should be provided with physical activity environments.

Published: April 2019

Background and Study Aim. Stability of performances at competitions with a preset effectiveness in the presence of sports competition is the result of the reliable functioning of the psyche of an athlete. The hypothesis of the study - mental reliability is associated with certain individual psychological properties, the similarity and difference of which is determined by the level of success of an athlete. The purpose of the study is to identify a set of personality determinants that affect the mental reliability of an athlete. Material and methods. The study involved 58 fencers aged 17-18 years (M = 17.47 SD = 0.53). In this paper, the measurement of the mental reliability of an athlete was carried out using an integral assessment of the success of sports activities developed by E.V. Melnik and E.V. Silich. According to the final success rate, the total sample of the subjects was divided into 2 groups: «successful» and «unsuccessful». For the study of the leading individual psychological properties of the personality, 16-PF multifactor personality questionnaire by R.Kettel was used in the work. The data processing package SPSS was used for data processing. Results. Significant differences were established between the groups of «successful» and «unsuccessful» athletes in the majority of individual psychological properties. The importance of focused analysis and the development of individual mental properties as internal prerequisites for the mental reliability of fencers has been acknowledged. The relationship of personal factors with the success in sports activities is presented. A high level of correlation between the integral indicator of the success of competitive activity and intelligence (factor B), emotional stability (factor C), emotional hardness (I), confidence (O), independence and autonomy (Q2) is revealed. A significant correlation was found between the average level of success in sports and caution (F). This confirms the possibility of applying the methods of research of individual psychological properties of a person when studying the causes of lesions and the prerequisites for the erroneous actions of an athlete. Conclusions . The success of sports activities of fencers does not depend on one individual psychological property of a person. This is the result of a combination of most of them. A greater number of reliable relationships have been revealed between the final indicator of the fencers’ success in sports activities and personal factors from the emotional properties group as compared to communicative and intellectual properties groups.
The TRUST Untruthfulness Framework in Forensic Contexts
Authors: Heffer Chris
Published: April 2019

This article introduces a comprehensive linguistic-ethical framework for analysing untruthfulness in situated discourse, as developed in much more depth in Heffer (in press). The TRUST (Trust-Related Untruthfulness in Situated Text) framework extends the analysis of insincerity beyond lying to misleading and withholding. More radically, it extends our conception of untruthfulness to include not only insincerity but also epistemic irresponsibility, or not taking care in establishing and conveying the evidence. The TRUST heuristic then provides a practical procedure for analysing putative cases of untruthfulness in situated discourse. This heuristic is then applied to two cases of putative untruthfulness in the legal process: the Bronston perjury case in the US and the Iraq Inquiry in the UK.
An exploration of the legal translator’s subjectivity
Authors: Shi Junjun
Published: April 2019

The empirical research presented in this paper is an attempt to investigate the legal translator’s subjectivity through analyzing the English-Chinese translation of the WTO agreement, TRIPS. The translator’s subjectivity is located in the framework of cognitive linguistics, which lends operational dimensions to the current study. Through examining one of these dimensions, explicitation and implicitation, this paper aims to reveal how legal translators exert subjectivity.
Local recontextualization in Chinese-English court decisions translation
Authors: Qijing Wu
Published: April 2019

Local recontextualization refers to the change in the contextualization of grammatical units at the rank of the word group. It provides a description of the local environment for meaning reconfiguration, and thus plays a key role in the translation of court decisions. Through a purpose-built parallel corpus of Chinese court decisions and their English translations, this study explores the recontextualization of Chinese nominal groups with de based on the analysis of their multivariate structures and the meaning of functional elements providing their (re)contextualization. By comparing the differences in contextualization and recontextualization of nominal groups, this study reveals that nominal groups tend to be contextualized by the Qualifier and the Deictic in Chinese court decisions, and re-contextualized by the Deictic and the Thing in their English translations. In most of the nominal groups, the functional elements with contextualizing roles focus on both experiential meaning and interpersonal meaning while those with recontextualizing roles contribute more to the experiential meaning. The reasons that account for these differences between contextualization and recontextualization of nominal groups from linguistic and legal cultural perspectives are provided.
Do sentido formativo ao enigma da frieza: uma análise do filme “A Fita Branca”, de Michael Haneke
Authors: Peres Helga Caroline , Gomes Luiz Roberto
Published: April 2019

Retomaremos neste artigo alguns elementos que tangem o conceito de frieza. Esta, vinculada ao processo de reprodução material na sociedade burguesa, mostra-se como mal-estar cultural que se traduz na expressão da indiferença nas relações estabelecidas entre os sujeitos. Subsidiada pelo aporte da Teoria Crítica da Sociedade, a interlocução com o argumento em questão se dará através da análise do filme A Fita Branca [Das Weiße Band, 2009], do diretor austríaco Michael Haneke. Ao contrário de um cinema que se apresenta como narrativa casual, este filme traz ao espectador a experiência com os enigmas nele implicados, expressando, assim, o sentido formativo e educativo que lhe é intrínseco, e não atribuído a posteriori. Neste ínterim, a hipótese é a de que para além das alegorias que remontam ao embrião dos regimes totalitários, em geral, e do regime nazista na Alemanha, em particular, há também no filme de Haneke elementos enigmáticos que apontam para o conceito de frieza burguesa, e que podem vir a facultar no espectador a reflexão crítica sobre as condições que levaram a tal momento de barbárie.

Published: April 2019

O artigo discute as narrativas autobiográficas de professores como materiais de investigação e experiências de formação e problematiza as contribuições que a leitura de memoriais de formação elaboradas por estudantes e professores em formação podem suscitar nos seus formadores. A partir da leitura de um conjunto de 80 memoriais produzidas por professores de diversos níveis de ensino que frequentaram cursos de extensão e de pós-graduação lato sensu no período de 2008 a 2016 pretendeu-se responder as seguintes questões: o que podemos aprender, como formadores de professores, com as narrativas dos estudantes e professores em formação? Como as narrativas autobiográficas podem orientar nosso trabalho e reflexão como formadores de professores nas licenciaturas, na pós-graduação e nas demais ações de formação continuada? A análise dos memoriais buscou, na escolha semântica, na organização dos enunciados, no estilo dos autores, indícios das relações e processos vividos por eles durante o percurso na graduação. Nesse processo de análise chamaram a atenção aspectos relacionados à centralidade do conhecimento nos processos de formação; os modos de mediação do conhecimento pelo professor formador; a relação entre teoria e prática com especial enfoque para as práticas de estágio e de pesquisa.

This article was migrated. The article was marked as recommended. BackgroundPhysicians are typically appointed to leadership roles within health care organizations on the basis of individual accomplishments in research, education, and/or clinical care. However, these types of achievements seldom provide the requisite management capabilities to lead within health organizations. In this manuscript, we described our initial experience in developing an in-house program to provide current and aspiring physician leaders with the managerial capabilities to enhance the quality of health care delivery within their respective organization. MethodsIn a partnership established between a Medical School and a Business School, we designed two series of weekend workshops to provide current and aspiring physician leaders with the financial capabilities to assist them in their future healthcare leadership careers. This course was then expanded to a Management Principles for Physician workshop with open enrollment to physicians at all levels. Baseline demographics and participant evaluations of each course were recorded. In the open enrollment Management Principles for Physician workshop, we examined the relationship between participant background and their course evaluations as well as their areas of interest for further training.ResultsAll 3 workshops received excellent evaluations by participants. The positive impact of the open enrollment program, based on participants' self-evaluations, was the highest in female physicians, as well as early to mid-career physicians. Additionally, physicians who do not currently hold leadership positions and those who are leading at Divisional levels were the most interested in further training in finance.ConclusionIn summary, this series of workshops demonstrated the feasibility of an in-house physician leadership program and yielded important information for the design of future leadership development curriculum.

Methods to produce a recombinant fungus and measure the viruence of this strain to mosquitoes v1
Authors: Deng Shengqun
Published: April 2019

In our study, the Cyt2Ba gene was introduced into the B. bassiana genome by genetic engineering to improve fungal virulence. The Cyt2Ba gene was stably inherited in the Bb-Cyt2Ba strain. RT-PCR and western blot analyses also confirmed that the recombinant strain expressed the Cyt2Ba toxin stably, but not the WT strain. The efficacy of Bb-Cyt2Ba was evaluated against larval and adult Aedes mosquitoes (Ae. aegypti and Ae. albopictus) using insect bioassays. The mosquitoes treated with Bb-Cyt2Ba tended to die faster than those treated with the wild-type strain at the same concentration, and the difference was significant. In addition, the fecundity of female mosquitoes was significantly reduced by Bb-Cyt2Ba infection compared with WT infection.

Authors: KESICI Ahmet
Published: April 2019

This study was conducted to determine the change in the sociability levels of high school students depending on the frequency of their using social media and to investigate their social media uses. It employed a mixed-methods research design using both quantitative and qualitative methods together. The sociability levels of 352 students studying in Siirt in 2018 were determined through the “Extraversion” sub-dimension of the Big Five Inventory for this purpose. Accordingly, it was found out that the sociability points of the students differed significantly depending on the frequency of their Youtube, Instagram, and WhatsApp use, but not depending on the frequency of their Facebook use. In addition, the social media uses of the students were investigated with semi-structured interviews made with 27 students who were social and often used social media. In accordance with this aim, the participants were found to use Youtube for entertaining and learning, Instagram for communicating and entertaining, and WhatsApp for communicating. It was concluded in the interviews that the social media uses of the students who often used social media reflect their sociability traits.

Published: April 2019

The article analyzes the results of treating 545 elderly and senile patients with complicated forms of colon cancer and severe concomitant pathology. Depending on the method of surgical treatment, the patients were divided into two groups. The control group consisted of 408 patients, who were performed traditional surgery without investigating the Tei index. The patients of the main group were operated using endovideosurgical technologies. In addition, the calculation of systolic-diastolic ratio by means of Doppler echocardiography was carried out. Measuring the Tei index allowed correcting cardiovascular risk in the perioperative period, thereby increasing operability and reducing the number of postoperative cardiac complications. The use of minimally invasive methods of surgical treatment for colon cancer contributed to a decrease in the frequency of postoperative complications. Thus, it contributed to reducing hospital mortality from 29.9% to 2.2%.

This article proposes historical precedents for policies which support journalism enterprises that serve populations 'on the move' using communications networks and technologies. A contemporary case study is used to support an economic argument that there is a rationale for continued governmental intervention in journalism in the sphere of the international and domestic movement of passengers, cargo and discrete groups of linked individuals. It concludes that this sphere represents a valuable productivity opportunity for Australia which the Federal Government should exploit.

In this issue we consider how telecommunication companies around the world have been disrupted by the demand for improved network speeds, capacity and reliability and the growth of the smart device manufacturers that have become more closely linked with the handful of global digital giants. The pace of change has increased, if that is possible, and it is not unthinkable that further consolidation of the telecommunications market might occur in the next decade.
Telecommunications Market Evolution
Authors: Gregory Mark A
Published: April 2019

It would be wrong to expect stability in any large and complex industry today. The Australian telecommunications industry is no exception and in the lead-up to 2017 there have been a number of government reviews and inquiries announced that are certain to add to the instability if the outcomes do not focus on the long-term interests of end users. Whilst stability may not be achievable in an industry that is dependent on rapidly changing technology, there are aspects of telecommunications competition policy that are broken and need to be fixed urgently. Now is not the time to take an axe to the telecommunications competition legislation, especially when the underlying causes of the instability are not being tackled. Mr Graham Shepherd, a leading member of the Telecommunications Association Board and the Journal Board for many years, has retired from the Telecommunications Association Board.

This study explores causal relationships between fixed broadband penetration, gross capital accumulation, the degree of urbanisation, and economic growth, using panel data from 9 ASEAN member countries in 2003-2016. Employing multivariate models, we reveal bidirectional causality between fixed broadband penetration and economic growth, with a higher magnitude of effect from GDP per capita to broadband penetration. Furthermore, fixed broadband penetration has bidirectional causality to urbanisation, while a unidirectional link exists from fixed broadband penetration to gross capital accumulation.

Background: Breastfeeding is considered an optimal feeding method, as it fulfills the infants' nutritional needs. Exclusive breastfeeding (EBF), which means to feed an infant solely (with some exceptions) on breast milk, is important for the health and well-being of both infant and mother. However, implementing an effective health education program is essential for promoting EBF and improving health awareness. Therefore, the purpose of this study is to measure mothers’ beliefs, knowledge and practice of exclusive breastfeeding before and after implementing the breastfeeding health education program at King Fahd Armed Forces Hospital (KFAFH).Methods: This study employs a quantitative research method and uses a cross-sectional study design. All in-patient and out-patient postnatal women who received information about EBF in their third trimester were evaluated post-delivery. In the period from December 2018 to March 2019, the total number of participants is (n=234).Results: The study indicates a statistically significant positive association between EBF knowledge and practice evaluation scores. Higher levels of breastfeeding (BF) knowledge were found to translate into better BF practice. Knowledge scores also had a significant association with beliefs, with higher knowledge being linked to more positive beliefs in relation to BF.Conclusions: The conducted study reports the major effect of health education intervention on EBF practice among the KFAFH population. As a result, some managerial, and clinical recommendations were addressed. Other recommendations focused on working mothers, as KFAFH may employ some strategies and polices to maximize the use of EBF.

Listy księdza Jana Piotrowskiego, „przyjaciela z Dworu”, o wojsku w obozie pod Pskowem w 1581 roku
Authors: Bołdyrew Aleksander
Published: April 2019

Problematyka życia codziennego w obozie wojskowym w epoce wczesnonowożytnej nie była, jak dotąd (poza nielicznymi wyjątkami), przedmiotem osobnego studium. Szczególnie interesujące wydaje się skupienie na tej kwestii w odniesieniu do wypraw inflanckich Stefana I Batorego, zwłaszcza ostatniej z nich (Psków – 1581 r.). Prócz oficjalnej dokumentacji o charakterze politycznych oraz stosunkowo nieźle zachowanych źródeł natury wojskowo-skarbowej, dysponujemy bowiem dziennikiem Jana Piotrowskiego, uczestnika tych wydarzeń. W formie obszernych listów informował on o przebiegu działań zbrojnych, ale również o nastrojach wśród żołnierzy. Niejednokrotnie pisał także o warunkach codziennego bytowania wojska w obozie (w marszu i podczas oblężeń), sposobach i okolicznościach zdobywania żywności, warunkach pomieszkiwania w obozie wojskowym, kwestiach sanitarnych i zdrowotnych. Jego zapiski doskonale uzupełniają diariusze Łukasza Działyńskiego i Jana Zborowskiego.
Obraz armii rosyjskiej w okupowanej Galicji w świetle dzienników i wspomnień (1914–1915)
Authors: Florczak Ilona
Published: April 2019

Celem niniejszego artykułu jest przedstawienie obrazu armii rosyjskiej, wyłaniającego się z dzienników i wspomnień, powstałych w okupowanych przez Rosjan miastach Galicji Wschodniej. W drugiej połowie sierpnia 1914 r. wojska rosyjskie wkroczyły do Galicji i w wyniku zwycięskiej ofensywy zajęły najważniejsze centra administracyjne na tych terenach, a mianowicie Tarnopol i Lwów. W marcu 1915 r., po drugim oblężeniu, poddał się Przemyśl. Autorzy wykorzystanych w tekście wspomnień na co dzień stykali się z przedstawicielami wrogiej armii i z tej perspektywy opisywali spostrzeżenia dotyczące rosyjskiej siły zbrojnej.
Morals in the United States of America: Are they in their death throes?
Authors: Cook John A.
Published: April 2019

This article explores the ethics of large complex systems in the United States of America in three major case studies: the food industry, the pharmaceutical industry and the political/governmental institutions. Using the simple Aristotelian heuristic of good sense, good character and good will, the conclusion is that ethics is not a high priority due in large part to the relentless pursuit of large sums of money at any cost.
The ageing of society in the context of dominant assumptions of contemporary economics and culture
Authors: Michalski Michał A.
Published: April 2019

Current demographic trends indicate that the process of ageing is more and more advanced in Western societies. While the available literature addressing this issue concentrates most often on developing effective tools for socio-economic policy, this paper aims at exploring the dominating assumptions of economics and culture to find how they may influence the demographic process that was mentioned. The purpose of the analysis undertaken here is to verify the thesis which claims that basic anthropological assumptions present in neoclassical economics and modern culture somehow ignore or underestimate such essential aspects of human life as old age and the helplessness or weakness connected with it. The conclusions of the paper indicate that there is a need for intergenerational balance within society, which, e.g., facilitates socio-economic development. Some of the most important factors influencing this may or may not be present within the economic theory and culture it is based on. It means that without the adequate vision of man and the phases of human life, the process of building a mentally healthy and vibrant society where everyone has his or her place is hardly possible.
The essence of the Bank Guarantee Fund’s activity and related dilemmas in the context of banking system stability
Authors: Czechowska Iwona Dorota
Published: April 2019

The deposit guarantee system in Poland was devised at the time of the economic transformation. Its creation resulted from a difficult situation in the banking sector, and so it was meant to be an antidote to clients’ problems associated with the insolvency of collapsing banks and with adjusting to European community law. The aim of this work is to present the Bank Guarantee Fund—an institution that is part of the financial safety net, whose main task is to protect the interest of depositors and to ensure the banking system’s stability. The paper looks at some aspects of the growing interest in bank deposit insurance schemes and lively discussions on the subject during a crisis in banking markets. In response to the crisis that started in the subprime lending market in the USA and spread to other segments of the financial markets as well as to other countries, the ECOFIN made a decision to increase the existing guarantee limits for individual persons and to speed up the payout of guaranteed funds. The above changes were aimed at strengthening the security of clients and increasing confidence in the banking sector.
