Authors: Isa Dwijatmoko Muhammad , Nurtama Budi , Dewi Yuliana Nancy , Misnawi Misnawi
Published: October 2019

Cocoa bean is a rich source of polyphenols, which are the largest group secondary metabolite with natural antioxidant property. Polyphenols from cocoabeans was reported to possess health benefits. Fermentation, one step in cocoa processing is needed to improve the quality of cocoa in which the concentration of cocoa bean polyphenols might decrease significantly through oxidation and exudation. Cocoa polyphenols content among different cocoa clones mightalso vary. The aims of this study were to determine total polyphenols, total flavanoid, epicatechin, and catechin content in several cocoa clones, those wereSulawesi 1, Sulawesi 2, ICCRI 03, and KW 617. Until now, characterization of polyphenols from those clones has not been reported. The effect of five daysfermentation to those parameters was also studied. The results of the study showed that fermentation and type of clones significantly affected total of polyphenols, total of flavanoids, epicatechin, and catechin content of the cocoa, there is also an interaction between fermentation and type of clones. Unfermented of Sulawesi 1 had the highest total polyphenols of 96.94±5.83 mg/g, total flavanoids of 90.92±1.89 mg/g, epicatechin of 52.50±0.46 mg/g, and catechin of 1.99±0.02 mg/g content compared to other clones. Among five days fermented cocoa beans, Sulawesi 2 showed the highest total polyphenols and total flavanoids content, while ICCRI 03 had the highest epicatechin and catechin content than other clones. Thus, in can be concluded that although fermentation is required to improve the flavor quality of cocoa, it significantly reduced the content of bioactive compounds. This effect varied amongdifferent cocoa clones.

Published: October 2019

A study on nutrient absorption of Trinitario and Forastero cocoa types had been conducted in Kaliwining Experimental Garden and the laboratory of plant analysis of the Jember Research Institute for Estate Crops (JRIEC) since June 1987 until March 1988.

Trinitario type was represented by four groups of cultivars i.e.Djati Roenggo (three DR series) Djati Roenggo Clone (13 DRC series), Kaliwining Clone (six KWC series), and Imperial College Selection (three ICS series). Forastero type was represented by two groups of cultivar, i.e. Getas Clone ( seven GC series),and Scavina (three Sea series). The seedlings of propelegitimate seeds were used.

The results showed that under the same environmental condition there were significant differences between the two cocoa types in the absorption of K, Mg, Cu, and Mn. Trinitario type showed high absorption for K and Mn, but lower in the absorption of Mg and Cu compared to Forastero type.

Among cultivar's group within Trinitario type there were differences in the absorption of N, P, K, Mg, Cu, and Mn. ICS group showed high absorptionfor N, KWC for P and K, DRC for Cu, ICS for Mn, and DR, DRC and ICS for Mg. In the Forastero type, GC group showed high absorption for P, but Sea group had the highest absorption capacity for K, Mg, and Mn. No significant difference was observed between the series within each cultivar group.

Published: October 2019

O objetivo do estudo foi analisar o desenvolvimento humano em Farroupilha (Rio Grande do Sul), no período 2000/2010, com ênfase na dimensão trabalho. A metodologia empregada foi a análise do IDHM e de indicadores de desenvolvimento selecionados nesta dimensão. Os resultados revelaram que Farroupilha apresentou, em relação ao estado do Rio Grande do Sul, índices referentes ao desenvolvimento humano e à dimensão do trabalho, de modo geral, superiores. Destacam-se o IDHM Longevidade e o IDHM Educação, nos quais Farroupilha apresentou resultados melhores que a média do estado e ao município de Caxias do Sul, que foi utilizado como base comparativa. Em relação à dimensão trabalho, Farroupilha novamente obteve resultados, na maior parte, superiores aos do estado, com destaque para a maior evolução no nível de escolaridade dos ocupados e para a melhor distribuição de rendimentos, entretanto, quando comparado com Caxias do Sul, houve alternância na supremacia dos resultados.
ADAPTAR, ADEQUAR, DIFERENCIAR: reflexões a partir das políticas curriculares para o público-alvo da Educação Especial
Authors: Pires Yasmin Ramos , Mendes Geovana Mendonça Lunardi
Published: October 2019

O presente artigo tem como objetivo investigar como no conjunto de documentos que estamos nomeando como políticas curriculares, especialmente cinco textos curriculares criados pós Política Nacional de Educação Especial na perspectiva da Educação Inclusiva, em 2008, vêm evidenciando movimentos curriculares como adaptação, adequação ou diferenciação curricular como formas de inclusão do público-alvo da Educação Especial. O desenvolvimento metodológico deste trabalho deu-se por meio de pesquisa documental, investigando-se alguns dos textos políticos se referem a estes movimentos e que advogam na defesa de um determinado termo como processo de inclusão. Esta pesquisa fez parte do projeto intitulado “Escolarização de alunos com deficiência intelectual: políticas públicas, processos cognitivos e avaliação da aprendizagem” que procurou investigar as formas de escolarização dos alunos com deficiência intelectual inseridos na sala de aula regular e no Atendimento Educacional Especializado. Essa discussão, portanto, é um aprofundamento de questões curriculares presentes no projeto.  A análise das políticas curriculares realizadas neste artigo identificou que poucas são as evidências dos movimentos curriculares de adaptação, flexibilização e/ou diferenciação curricular como possibilidades para a inclusão dos alunos público-alvo da Educação Especial. De acordo com a leitura atenta, por meio das políticas curriculares pesquisadas, os tipos de movimentos curriculares aqui conceituados não são representados como formas efetivas de possibilidade de trabalho pedagógico para o público-alvo da Educação Especial.
DA MEMÓRIA: movimentos de “não esquecer” em currículos de Língua Portuguesa da cidade de São Paulo.
Authors: Costa Felipe De Souza
Published: October 2019

Este artigo tem como objetivo verificar como a categoria “memória discursiva” permite movimentos de esquecimento e lembrança, principalmente no que diz respeito à concepção de linguagem, a partir de um corpus constituído por cinco documentos curriculares de Língua Portuguesa, publicados em gestões e épocas diferentes, os quais foram coletados no setor de Memória Técnica da Secretaria Municipal de Educação de São Paulo. Para tanto, filiamo-nos à Análise do Discurso de orientação francesa para discutir os dados. A categoria de análise, em confronto com os dados, demonstrou que o esquecimento e apagamento de concepções e abordagens propostas nos documentos curriculares estão, de alguma forma, ligadas a um ideário político-ideológico das gestões que atuaram na produção dos respectivos currículos.
MULHERES ENCARCERADAS: DIFICULDADES VIVENCIADAS ANTES, DURANTE E APÓS A PRISÃO
Authors: Leal Tatiana Cavalcanti de Albuquerque , Monteiro Anielle Oliveira
Published: October 2019

Reiteradas estatísticas revelam um perfil bastante comum da população carcerária feminina: mulheres jovens, solteiras, não brancas, com baixa escolaridade e que cometeram crimes relacionados ao tráfico de drogas. Muitas vieram de contextos de violência prévios e a prisão se encaixa como mais um elo na cadeia de violências vivida. Este ciclo da violência se inicia na família e nas instituições para crianças e adolescentes, continua no casamento, desdobra-se na ação tradicional das polícias e finaliza na penitenciária. Isto porque a múltipla penalização na prisão ultrapassa a pena de reclusão, abarcando castigos corporais, ambientes insalubres, exposição às drogas, contágio de várias doenças e abandono familiar. Assim, o objetivo deste artigo foi conhecer quais foram as maiores dificuldades vivenciadas antes, durante e após o cárcere para mulheres já em livramento condicional. Trata-se de uma análise documental de pareceres psicossociais de mulheres realizados entre junho de 2013 e junho de 2014 na Vara de Execuções Penais do Fórum Criminal de João Pessoa/PB. Foram encontrados 12 pareceres, analisados por meio da técnica de análise de conteúdo de Bardin. As dificuldades vividas antes do cárcere foram categorizadas como “Abandono parental”, “Trabalho precoce”, “Doenças crônicas na infância/adolescência”, “Abuso sexual”, “Relacionamentos abusivos” e “Aliciamento ao crime por figuras masculinas”. Durante o cárcere, as dificuldades encontradas foram “Solidão” e “Estratégias de resistência”. Depois da prisão, os problemas foram classificados em “Saúde comprometida” e “Dificuldade financeira ou de inserção no mercado de trabalho”. O conjunto dos resultados revelou, de fato, histórias atravessadas por vulnerabilidades sociais e um ciclo de violências que pode começar com o abandono pelos pais na infância, passando por abusos diversos, aliciamento ao crime por homens próximos e penalizações adicionais no cárcere, e terminar com a condição socioeconômica precária e exclusão do mercado de trabalho depois da prisão.
O “NÃO LUGAR” DOS TRANSGÊNEROS NA PREVIDÊNCIA SOCIAL BRASILEIRA: ARTICULAÇÕES ACERCA DA PREVIDÊNCIA AO PÚBLICO LGBTTTI
Authors: Demari Melissa , Trentin Eduarda Groff
Published: October 2019

O sistema previdenciário brasileiro atual pressupõe determinados requisitos a serem preenchidos pelo segurado para a concessão dos benefícios em espécie. Tais requisitos, em alguns deles, pressupõem uma distinção de gênero, sendo comum que sejam distintos se o beneficiário for homem ou mulher. Contudo, a dicotomia de gênero na qual tais requisitos legais se baseiam, não consegue mais contemplar a complexidade da vida, especialmente no que toca à diversidade de gênero e sexual. Tendo isso em mente, é essencial que os requisitos legais à concessão de benefícios sejam revistos. Dentre os vários questionamentos que se apresentam, um dos mais polêmicos envolve a questão do transgênero que, nascido e registrado num gênero determinado, adota outro ao longo da vida. Neste caso, será tratado pelo sistema previdenciário a partir dos requisitos impostos ao gênero registral de nascença ou ao social? Diante do silêncio legal para questões como esta, uma possibilidade que se apresenta é que o segurado seja tratado proporcionalmente ao tempo de contribuição em num e noutro gênero, ao menos até que a legislação e os tribunais avancem nos debates e nas propostas de solução. Tal solução apresenta-se como uma possibilidade pela qual estaria respeitada a história pretérita e a atual do segurado, garantindo-se tratamento alinhado com o gênero presente.

Os registros de violência doméstica no Brasil cresceram nos últimos anos, conforme dados fornecidos pelo Conselho Nacional de Justiça (CNJ). Para combater esse problema, sancionou-se a Lei Maria da Penha, nº 11.340, que entre seus mecanismos de coibição prevê a atuação de grupos de atendimento para homens (art. 30 e 45) e mulheres (art. 30) em contexto de violência doméstica. Em busca de compreender melhor o funcionamento e benefícios do atendimento psicossocial em formato de grupo para mulheres vítimas desse tipo de violência, realizou-se esta pesquisa. O presente estudo trata de uma pesquisa qualitativa, descritiva e exploratória, realizada com 06 mulheres atendidas pelo Grupo Reflexivo para Mulheres e Homens em Situação de Violência Doméstica – Aequalitas, realizado pelo Tribunal de Justiça do Estado de Rondônia, comarca de Pimenta Bueno. Aplicou-se um questionário sociodemográfico e de percepção sobre o funcionamento do grupo. Os resultados demonstram que o grupo influiu de modo positivo na vida das participantes com relatos de transformação no sistema de família, o que sugere a importância desse tipo de atendimento no Sistema de Justiça, dada sua eficácia e benefícios advindos de suas ações.
DEVELOPMENT OF THE CONTENT AND FUNCTIONS OF A FIRM WITH THE ACCOUNT OF THE ECONOMIC DISEQUILIBRIUM CONDITIONS
Authors: Saubanov Kabir , Nikolaev Mikhail
Published: October 2019

The paper examines the actual problem which is a complex and contradictory process of origin, formation and development of a firm and its functions. It is shown that the structure of a firm, the features of its organization, the nature of the functions performed and the changes occurring therein have a great influence on the efficiency of management, on the properties and characteristics of economic systems. It is within its framework that a complex process of interaction between all factors of human life activity: historical, natural, cultural, economic, including the basic principles and types of long-term behavior of economic agents are formed. All that has been said undoubtedly confirms the relevance of the topic under research. However, despite the importance of solving these problems, up to the present time there is no single understanding of the concept “firm”, nor a generally accepted view of its nature and functions. In the paper, all these issues are considered in relation to various stages of economic evolution and in the context of several main approaches: classical, institutional, evolutionary and behavioral, in which the concepts of the firm, its nature and functions are significantly different. The main directions of gradual changes in views on the institution of “firm” are shown: a consistent departure, and then a complete rejection of the principle of rationality, which was decisive at the stage of domination of the classical approach; weakening the importance of the theory of general equilibrium; creation of “company” models, first, describing its behavior in the real conditions of economic uncertainty and a disequilibrium environment, secondly, orienting in making decisions not for the best, but for an acceptable result

Development of the Russian economy is accompanied by qualitative changes in the ethnonational sphere, what is manifested in the growth of the scales of integration processes, formation of interethnic and supranational regional civilizational communities and megaethnoses. The objective basis for these changes lies in the material and spiritual culture of peoples, but, as the practice of ethnonational relations shows, they come in a contradictory and painful way, what makes it necessary to take them into account when forming measures for state regulation of the economy. At present, Russian society needs a new scientific paradigm reflecting the positive direction of development of national relations in the country and taking into account the experience of centuries-old cooperation between nations and peoples. The article presents an analysis of the main provisions and conclusions contained in the works of Moussa Akiegetzadeh, the creator of the first major art work in the Tatar language of the last quarter of the 19th century and the founder of the system of economic views, in which the achievements of world and Russian economic science, as well as Islamic traditions were synthesized, and popularizer of these ideas in the Ottoman Empire in the era of Mesrutiat (Parliamentarism) and the following years. The thesis is substantiated, according to which historical and economic knowledge acts as one of the sources for elaboration of the program documents of the Russian state in formation of regional development targets; the possibility of their realization is being determined by complete inclusion of the totality of cultural, historical, social, religious features of territorial entities

Published: October 2019

Today there is a profound transformation of the traditional money and finance world. Innovations in the financial sector, new technologies, tools and systems entail serious and profound changes in the financial institutions that are familiar to us. One of the most important stages of these transformation processes was the emergence of crypto currencies, accompanied by the rapid development of related technologies and the lack of a clear picture of the future landscape of ecosystems.The search for scientifically grounded mechanisms that reveal the specific features of the impact of the crypto currency market legalization processes on national economic systems contributes significantly to an understanding and objective perception of the prospects for their development. This paper is devoted to solving this problem. The object of the study is the global crypto currency market, which forms the institutional and conjunctural parameters of the national economic systems development. As the subject of the study is the process of designing and scientific and methodological justification of the prospects, opportunities and risks of the development of the national economy formed as a result of the legalization of the crypto currency market.As a result of the conducted studies and implemented assessments, scientifically grounded hypotheses on the influence of the "digital money" legalization mechanisms on key macroeconomic processes have been formed

Published: October 2019

El objetivo de a presente investigación es realizar un estudio para determinar el grado de acoso laboral o mobbing percibido en el personal docente de una Institución de educación superior (IES) pública, ubicada en la parte central del estado de Hidalgo, basada en la postura teórica y conceptual de Leymann. Esta investigación considera la conceptualización del fenómeno del mobbing, desde sus antecedentes, conceptos y estudios en el contexto organizacional. El instrumento que permite la medición del mobbing, sustentado con validez y confiabilidad es el cuestionario denominado LIPT-60 («Leymann Inventory of Psychological Terrorization»). Los resultados obtenidos describen la existencia del mobbing en la institución de educación superior, con valores observados por debajo del nivel 1, específicamente en las subescalas de Desprestigio laboral, Incomunicación, e Intimidación manifiesta. Es por ello que en las instituciones de educación superior es fundamental realizar este tipo de trabajos con la finalidad de identificar, evaluar y conocer si existen riesgos de acoso laboral, para estar en posibilidad si así fuera el caso de disponer de medidas preventivas oportunas. En este contexto, el analizar los resultados permitirá establecer estrategias de prevención para disminuir o erradicar el acoso laboral en esta organización.

El estudio de los pronósticos como elementos en la toma de decisiones en las empresas tienen mayores áreas de oportunidad al interior de las organizaciones  , esto se debe a que  los pronóstico ayudan a los tomadores de decisiones a realizar juicios más precisos acerca de los eventos futuros y en esta parte las matemáticas resultan tener un papel importante, tal y como lo mencionan (Wilson & Koerber, 1992) se ha demostrado que los métodos cuantitativos son útiles para hacer mejores pronósticos acerca del rumbo futuro de los eventos, por lo que se ha creado la necesidad que se desarrollen nuevos software que a través del uso de la computadora se generen más rápidamente estas predicciones, pero resulta fundamental comprender bien como se realizan los cálculos manualmente para utilizar posteriormente estas herramientas computacionales.

Para los fines de conocimiento que el administrador requiere saber sobre los diferentes métodos de pronósticos y con ello seleccionar el que cumpla con los objetivos internos, el autor Farrera Gutiérrez (2012) los divide en: Métodos Cualitativos entre los cuales se encuentran: Métodos Delphi, Analogía Histórica e Investigación de Mercados.  Dentro de los Métodos Cuantitativos se encuentran: Promedio Móviles, Suavización Exponencial y Regresión Lineal. Es importante destacar que el conocer los diferentes métodos de pronósticos permite al tomador de decisiones al frente de una mipyme, acercarse lo más exacto a saber el comportamiento que tendrán los datos sobre los que se genera sus estimaciones a futuro.

Published: October 2019

Ba0.75Sr0.25TiO3 (BST) and PbZr0.68Fe0.14Nb0.14Ti0.04O3 (PZFNT) ceramic
pellets were obtained by ceramic technology and their structural,
ferroelectric and pyroelectric properties were investigated. The relative
density of BST and PZFNT is about 93% and 90%, respectively, with an average
grain size of 102 ?m and 6.45 ?m. Both materials have similar room
temperature dielectric constants (~2000), but PZFNT shows higher remnant
polarization (~15?C/cm2) and better pyroelectric properties (~1.69?10?4
C/m2K), which recommend it for pyroelectric detectors, infrared radiation-
and laser pulse energy-meters.

Published: October 2019

Biphasic calcium phosphate (BCP) was fabricated through hot pressing process
from hydroxyapatite (HA) starting powder synthesized by a peroxide-based
precipitation method and dried at 250?C. The synthesized HA powder contained
some calcium hydrogen phosphate (CHP) as a minor phase. In this work, the
dense BCP ceramics with a mixture of HA and ?-TCP phases were successfully
obtained by hot pressing at temperature ranging from 700-1100?C. The amount
of HA phase in the hot pressed samples decreased with increasing sintering
temperature from 700 to 900?C, while the amount of ?-TCP exhibited an
opposite trend. The relations between the microstructure and mechanical
properties of the dense BCP ceramics sintered in the temperature range
700-1100?C were investigated. The sample hot pressed at 800?C has a dense
structure with the highest hardness (4.86 ? 0.19GPa) and the lowest fracture
toughness (0.80 ? 0.01MPa?m1/2). In addition, biocompatibility of apatite
layer formed after immersion in simulated body fluid (SBF) for 14 days can be
observed by SEM images. The results revealed that the samples hot-pressed at
800 and 900?C were covered by calcium phosphate (CaP) crystal layer
indicating the strong interaction of BCP ceramics and SBF.
Why Pay Our Fair Share? How Perceived Influence over Laws Affects Tax Evasion
Authors: Mason Paul D. , Utke Steven , Williams Brian M.
Published: October 2019

We examine how the relation between taxpayers and their government affects tax evasion. Specifically, we examine how perceived influence over government policymaking affects firms' decisions to evade tax. We argue that firms are less willing to comply with tax laws when they perceive the influence over their government to be unfavorable to them or the result of an unfair policymaking process. Consistent with this argument, we find that firms evade more tax when other domestic firms have more perceived influence over domestic government policymaking. This suggests a potential negative externality of lobbying: higher tax evasion by other firms. However, government effectiveness or lack of corruption eliminates the positive relation between evasion and perceived influence over policymaking. Our study is the first to document the relation between perceived influence over government policymaking and tax evasion. Our results suggest that limiting domestic firms' influence over policymaking could help governments decrease tax evasion.

Finite element study of controlling factors of anterior intrusion and torque during Temporary Skeletal Anchorage Device (TSAD) dependent en masse retraction without posterior appliances: Biocreative hybrid retractor (CH-retractor)
Authors: Mo Sung-Seo , Noh Min-Ki , Kim Seong-Hun , Chung Kyu-Rhim , Nelson Gerald
Published: October 2019

Objectives:

To evaluate, using the finite element method (FEM), the factors that allow control of the anterior teeth during en masse retraction with the Biocreative hybrid retractor (CH-retractor) using different sizes of nickel-titanium (NiTi) archwires and various gable bends on the stainless-steel (SS) archwires.

Materials and Methods:

Using FEM, the anterior archwire section, engaged on the anterior dentition, was modeled in NiTi, and another assembly, the posterior guiding archwire, was modeled in SS. Two dimensions (0.016 × 0.022- and 0.017 × 0.025-inch NiTi) of the anterior archwires and different degrees (0°, 15°, 30°, 45°, and 60°) of the gable bends on the guiding wire were applied to the CH-retractor on the anterior segment to evaluate torque and intrusion with 100-g retraction force to TSADs. Finite element analysis permitted sophisticated analysis of anterior tooth displacement.

Results:

With a 0° gable bend all anterior teeth experienced extrusion. The canines showed a larger amount of extrusion than did the central and lateral incisors. With a gable bend of >15°, all anterior teeth exhibited intrusion. Bodily movement of the central incisor required a 30°∼45° gable bend when using anterior segments of 0.016 × 0.022-inch NiTi and 15°∼30° gable bend with the 0.017 × 0.025-inch NiTi.

Conclusions:

With the CH-retractor, varying the size of the NiTi archwire and/or varying the amount of gable bend on the SS archwire affects control of the anterior teeth during en masse retraction without a posterior appliance.

Effect on the microcirculatory bed of the bony tissue is one of promising approaches to treatment of osteoporosis.
Aim. To study anti-osteoporotic properties of endothelioprotectors: L-arginine, L-norvaline and rosuvastatin.
Materials and Methods. Osteoprotective properties of L-arginine, L-norvaline and rosuvastatin, and also of a reference drug– strontium ranelate – were studied on 152 female rats of Wistar line using a model of hypoestrogen-induced osteoporosis. Anti-osteoporotic and endothelioprotective effect of the drugs were evaluated by laser dopplerflowmetry (LDF) of the proximal metaphysis of the femoral bone, morphometry of trabeculae of bone, and also by calculation of the coefficient of endothelial dysfunction.
Results. LDF showed that maximal increase in microcirculation of the proximal metaphysis of the femoral bone, in comparison with animals with untreated osteoporosis (61.52±3.74 perfusion units, PU) was achieved with L-norvaline (115.25±5.36 PU, p<0.001) and rosuvastatin (106.57±5.22 PU, p<0.001), less expressed effect was demonstrated by L-arginine (98.10±4.48 PU, p<0.001) and a reference drug – strontium ranelate (86.49±4.99 PU). A similar tendency was observed in morphometry of trabeculae of bone: in the group with untreated osteoporosis the diameter of trabeculae was 61.68±1.24 µm, in the group with use fL-norvaline – 91.86±1.8 µm (p<0.001), in the group with use of L-arginine – 86.64±1.39 µm (p<0.001) and in the group with use of strontium ranelate – 89.08±1.09 µm.
Conclusion. L-arginine and L-norvaline and also rosuvastatin possess the property of improving a morphofunctional condition of bone tissue and may be recommended for further preclinical study.

Published: October 2019

Aim. To study the level of fetuin-A (FA), bone mineral density (BMD) and certain markers of bone remodeling in patients with rheumatoid arthritis (RA).
Materials and Methods. 110 Patients with RA and 30 conventionally healthy patients were examined. In both groups the levels of FA and BMD were determined. In the group of patients with RA the levels of C-telopeptide of type I collagen, N-terminal propeptide of procollagen I, 25-hydroxy-cholecalciferol, total alkaline phosphatase, total calcium of blood were determined.
Results. The mean concentration of FA in blood serum of patients with RA was 765.67±120.66 µg/mL, which was below the respective parameter in donors – 812.95±76.21 µg/mL (p=0.0437). In the group of patients with RA with osteoporosis (n=52) the mean level of FA was 733.65±135.84 µg/mL, and in the group without osteoporosis – 794.37±97.7 µg/mL (p=0.0044). The level of FA was also reduced in patients with osteoporotic fractures (n=24) – 694.79±110.47 µg/mL against 785.45±116.43 µg/mL in patients without osteoporotic fractures (n=86; p=0.00091). A positive correlation relationship was found between the level of FA and BMD of L1-L4 (r=0.194; p=0.042), femoral neck (r=0.328; p<0.0001) and proximal femur (r=0.293; p=0.002), and the level of 25-hydroxy-cholecalciferol (r=0.259; p=0.006), and the negative correlation relationship – with C-telopeptide of type I collagen (r=-0.203; p=0.033).
Conclusions. Patients with RA with reduced FA level were characterized by a higher detection rate of osteoporosis and of osteoporotic fractures, and by a lower BMD of L2-L4, femoral bone and proximal femur. Besides, a lower level of FA was associated with a lower level of 25-hydroxy-cholecalciferol and with a higher level of C-telopeptide of type I collagen which permits to suggest existence of osteoprotective function in this glycoprotein.

Published: October 2019

The current issues of crime prevention related to the illegal search and (or) seizure of archaeological ob-jects from their sites are reviewed in the article. The prevention this kind of crimes as one of the most effective methods of combating illegal activities in the field of archeology, accompanied by the de-struction or da-mage of the cultural layer of the earth containing archeology items is reviewed in article. As one of the directions for the crime pre-vention is the possibility of legislatively restricting the circulation of technical means of searc-hing for objects (hidden in the ground, under water or in another environment), as the main weapon used in the illegal search and removal of archeological ob-jects from places of their occurrence. It is proposed to adopt a normative act restricting their circulation on the territory of the Russian Federation or its indi-vidual entities in order to limit the access of crimi-nals to technical means of searching for archaeolog-ical objects. The general provisions and contents of this document are presented. The author’s conclu-sions are based on the study of criminal cases, as well as materials on checks of reports related to ille-gal activities in the field of archeology in the Crimea and Krasnodar Territory.

Authors:   Chief Research Fellow of the Institute of Europe of the Russian Academy of Sciences, Sindeev Aleksey Aleksandrovich
Published: October 2019

The present paper continues a series of studies on current approaches to transforming security in the Federal Republic of Germany. The novelty of the study is to analyze the views of the “Alternative for Germany” Party, which advocates the renationaliza-tion of the fo-reign po-licy and security policy, as well as Germany’s claim to leadership in Europe. Furthermore the Party declares the necessity of normalization of relations with Russia, and that in-creases the significance of the study of its line by Russian scientists. The articles considers docu-ments of the party program, which the author con-siders as the key ones. The present work has no theoretical value, due to its subject. The author was bound to refuse from any practical recommenda-tions since the approach of the “Alternative For Germany” Party presents just one of the possible variants of the future course of events, and the arti-cle emphasizes this point.

Authors: Bashier Eihab B M
Published: October 2019

In this paper we use the L-curve method and the Morozov discrepancy principle for the estimation of the regularization parameter in the regularization of time-delayed optimal control computation. Zeroth order, first order and second order differential operators are considered. Two test examples show that the L-curve method and the two discrepancy principles give close estimations for the regularization parameters.

Authors: Niciejewska Marta , Kasian Serhii
Published: October 2019

The organization of space and working conditions is very important in terms of its effectiveness. Each professional work determines activities that support occupational safety and health at the workplace. Lack of proper working conditions but also the time of exposure to dangerous, burdensome or harmful factors has an impact on the effectiveness of the work performed. Lack of balance between work and leisure in turn results in a decrease in work efficiency. The scientific and didactic work of academic teachers is related to the occurrence of diversified occupational hazards with particular emphasis on those that are the cause of musculoskeletal disorders. In this elaboration, the research, analysis and evaluation of the work effectiveness of academic teachers have been carried out. A questionnaire and a direct interview have been used as a research method. In addition, the pain intensity in individual parts of the body has been assessed in the last 12 months depending on the age of research and teaching staff using the NMQ questionnaire (Nordic Musculoskeletal Questionnaire). For the purposes of the study, the survey was supplemented with the VAS (Visual Analogue Scale) scale to assess the severity of pain. The purpose of the paper is to evaluate the frequency and severity of musculoskeletal pain in academic teachers with regard to the effectiveness of their work
The Quality of the Decision-Making Process in Road Transport
Authors: Sałek Robert
Published: October 2019

The issue of quality is a very important aspect of the operation of transport companies. In relation to the area of their activity it primarily focuses on the quality of services provided, which can be verified e.g. on the basis of timeliness of deliveries or accepted complaints. This allows for examining the quality after providing the service in order to take future pro-quality actions. However, is it possible to affect the quality of services provided before their provision? The transport process itself is preceded with a range of actions taken within the framework of detailed planning and organization, which can significantly influence the quality of services. The decisions made at the management level are conditioned by many factors determining the course of future events, however, this is not always enough to make the process run uninterruptedly. Therefore, it is important to structure basic actions at the initial stage so as to allow the smooth conduct of the decision-making process for the specific task in order to subsequently focus on the detailed analysis of the actions planned. In the paper, the author attempts to characterize the fundamental factors affecting the decisions taken during the planning and organization of the transport process. The objective of the conducted research is to verify initial decisions and their significance for the improvement in the quality of transport services provided. There was conducted the algorithmization of actions and interpretation of their importance for the quality of decisions taken at the preparatory stage and during transport.
The Effect of Adding Slag, Achieved from Wastewater Sludge Incineration in Fluidized-Bed Furnace, on the Quality of Concrete
Authors: Pietrzak Alina
Published: October 2019

Due to a constant increase in generating the amount of sewage waste it is necessary to find an alternative method of its use or disposal. One of such methods can be utilization of sewage sludge in construction materials industry, particularly in concrete technology and other materials based on cement. It allows using waste materials as a passive additive (filler) or also as an active additive (replacement of part of bonding material). The article aims at presenting the analysis of the effect of adding slag, achieved from wastewater sludge incineration in sewage treatment plant, on properties and quality of concrete mix and hardened concrete. Using an experimental method, the researcher designed the composition of the control concrete mix, which was then modified by means of slag. For all concrete mixtures determined – air content with the use of pressure method and consistency measured by the use of concrete slump test. For all concrete series the following tests were conducted: compressive strength of concrete after 7, 28 and 56 days of maturing, frost resistance for 100 cycles of freezing and thawing, water absorption. The use of slag, ground once in the disintegrator, causes a decrease of in compressive strength of concrete samples in relation to the control concrete series as well as bigger decrease in compressive strength after frost resistance test.

Published: October 2019

The subject of the presented work was the analysis of the influence of the distance between the electrodes using in the coating process on the tribological properties of oxide coatings. Oxide coatings were prepared on EN AW-5251 aluminum alloy samples. The samples surfaces were subjected to hard anodizing process in a multicomponent electrolyte based on sulfuric acid with an addition of organic acids. Anodizing was carried out with a constant electric charge density of 180 A·min/dm2. The distances between the electrodes for subsequent samples increased every 0.125 m up to 1 m. The tribological partner in a sliding couple with oxide layers was pin of PEEK/BG. Tribological tests were conducted on a T-17 tester in reciprocating motion, in technically dry friction conditions. Before and after tribological test, examination of the geometrical structure of counter-specimens’ surface was carried out using the Form Talysurf contact profilographometer, via a 3D method. The most satisfactory tribological parameters were obtained for the PEEK/BG association with the coating produced at a distance between the electrodes equal to 0.25 m.

Use of the CIT Method for Quality Assessment of Catering Services
Authors: Ingaldi Manuela , Kotus Martin
Published: October 2019

When using various types of services, the customer may experience positive or negative situations, incidents. These incidents may affect the customer's satisfaction or dissatisfaction. Therefore, these incidents can be a source of very valuable information for the enterprise about the quality of the services it offers. The problem, however, is their analysis, because such incidents can affect different aspects of the service, but also, as mentioned earlier, can have a positive or negative impact on customer satisfaction. The Critical Incident Technique (CIT), often mentioned in the literature, can be used for such an analysis. With this method, it is possible to isolate situations that are typical of the negative and positive feelings of the customers, as well as to determine the frequency of their occurrence. The purpose of the papers was to analyze the quality of services offered by the chosen catering enterprise with use of CIT. The research took form of a direct interview with customers after delivery of the chosen service. Data obtained on this basis was analyzed: all incidents were first divided into groups and categories as well as positive and negative incidents, and then statistics for individual categories were presented. This research allowed to indicate the strengths and weaknesses of the research service, but at the same time to indicate the areas of potential improvement.
