СТАЛИЙ РОЗВИТОК РЕСУРСНОГО ПОТЕНЦІАЛУ ПРОДОВОЛЬЧОГО КОМПЛЕКСУ
Authors: Kоreniuk P.I.
Published: January 2020

В умовах певного зниження споживання основних продуктів харчування і калорійності добового раціону, актуальною є проблема відтворення природних ресурсів у продовольчому комплексі з позиції сталого розвитку та ефективного використання аграрного ресурсного потенціалу природного середовища. Оцінка динаміки розвитку зернового підкомплексу продовольчого комплексу для ефективного використання аграрного ресурсного потенціалу навколишнього середовища можлива через оцінку макроекономічних показників. Динаміка кількісних співвідношень між валовим внутрішнім продуктом держави і продукцією аграрного сектора демонструє зростання обсягу валового продукту у розрахунку на 1 особу. Скорочення площі сільськогосподарських угідь, відбувається при постійному збільшенні посівної площі соняшника, який є пріоритетною експортною культурою.Тенденції розвитку природно-ресурсного потенціалу продовольчого комплексу країни свідчать про зниження сільськогосподарських угідь. В останні роки збільшилися лише площі соняшнику, що є пріоритетною експортною культурою. Стратегічним напрямом вирішення кризи може бути реструктуризація зернового підкомплексу переробних галузей харчового комплексу на основі ефективного використання аграрно-ресурсного потенціалу довкілля. Україна має потужний аграрний природно-ресурсний потенціал завдяки своєму сприятливому економічному та географічному положенню, а також є потужні ринки продовольства та сировини (країни ЄС, Росія, Китай). Виснаження споживчого кошика працездатного населення на тлі зменшення частки сільськогосподарського виробництва у валовому продукті демонструє зміну пріоритетних видів виробництва. У той же час, зменшення площі сільськогосподарських угідь відбувається при постійному збільшенні площ соняшнику, що провокує дисбаланс у діяльності вітчизняної харчової та переробної промисловості, отже, подальше скорочення споживання та калорійності щоденного раціону, переорієнтація харчової та переробної галузей на імпортну сировину, подальше зниження вітчизняного сільського господарства.

Published: January 2020

The aim of the article is to substantiate theoretical and methodic approaches to comprehension of the role and importance of the strategy of customer service of an industrial enterprise in terms of achievement of its sustainable competitive advantages. The article is devoted to the study and actualization of the strategy of customer service of an industrial enterprise in the context of implementation of the strategic management concept. Solution of the tasks, outlined in the article, is secured by general scientific and specific methods of research, i.e. analysis and synthesis, systematization and generalization.The work has actualized the strategy of customer service of an industrial enterprise in the contexts of implementation of the strategic management concept. The research identifies barriers on the way of the market entry, which are set by producers with a high level of customer service. The main barriers include the used schemes of payment, imposing heavy dependence between a customer and a supplier, as well as arrangement of a broad chain of servicing establishments, which are located at the places of customers’ employment, completion of contracts on continuous supply services, creation of the image of competence concerning services supply. The article examines the features, characterizing customer service of high quality, and identifies relationship between the strategy of competitive advantages of an enterprise and the strategy of customer service.The article supplies argumentation that servicing has become an accelerator of partnership relations setting between a customer and a supplier, as well as of achievement of a high level of customers’ loyalty. Shaping of the policy of customer service is an important direction to reach a competitive advantage of an industrial enterprise. The work proposes measures to motivate employees to supply customer service of the appropriate quality, which will secure establishment and support of the corporative culture, focused on the company’s clients. The principal scientific fundamentals of the article can be applied in the practical operation of industrial enterprises.

The unwanted past and urban regeneration of Communist heritage cities. Case study: European Capitals of Culture (ECoC) Riga 2014, Pilsen 2015 and Wroclaw 2016
Authors: Turșie Corina
Published: January 2020

Within the ECoC programme, it has been argued that the European dimension is most visible when the candidates reflect their own history as a part of  European history, particularly when hinting at their involvement with the major ideologies of twentieth century, such as National Socialism or Communism. ECoC is about cities re-inventing their identities, re-narrating their history in a European context. But how should ex-communist cities deal with their unwanted past and narrate it in order to fit into the European dimension of the project? The focus of this investigation is on three ex-ECOCs from ex-Communist Europe, chosen for several reasons: geographical position (Central, Eastern/Northern European countries, ex-communist past, new membership of the European Union (since 2004), the year of holding the title (the two ECoC selection criteria exist since 2010). Using qualitative content analysis on a set of documents (application books, official web pages and ex-post evaluations) the study will offer an analysis of cities’ politics of memory and urban regeneration strategies.
Anniversary Emblem & Logotype Designs
Authors: Okur Çağlar
Published: January 2020

Corporate anniversaries are mostly used as a promotional event to increase the value of corporate identity of firms, business enterprises or their brands. They are also used to create investment trust or strengthen the relations between, employees and customers. What makes corporate anniversaries meaningful is the importance of their moral value of continuity. Signs that are designed to identify these moral values and indicate the anniversaries can be defined as “anniversary emblems.” The design and uniqueness of these emblems are important in the means of being remarkable and memorable. Thus creative and unique results can be achieved by converting the numbers of anniversaries into expressive signs. This article focuses on existing design approaches and examples of anniversary emblem designs.
Nostalgia after the communist regime in Romania
Authors: Teșculă Dan
Published: January 2020

The present paper focuses on the nostalgia after the communist regime in Romania. This small study is a general overview of the progress I have made during the period between march and august on my PhD thesis regarding the nostalgia after the communist regime in Romania. The research methodology used is somewhat new in the field of conteporary history research. The quasi-experimental study was used in order to see if there are significant differences in the way the well-defined social categories perceive the feeling of nostalgia after communism. The period we spanned in this study is the so-called Ceaușescu epoch for wich we have had the most material to work with. From a historiographycal stand-point, the subject is very new, up until now the studies that have appeared during the past years, take the form of articles published in scientific reviews. More studies will eventually show up in the years to come. During this study we have identified small differences between the groups, that posess almost no relevance to our hypothesis. Theoretically educated people know how to present their memories which later have served as an explanation as to why they are not nostalgic. Surprisingly the working class has almost the same perception as the educated people (the intellectuals).

Published: January 2020

Abstract. The aim of the study was to investigate the occurrence and severity of biotic stress factors, quality and agronomic parameters and its effect on yield and quality character of wheat genotypes. The experiment was conducted at Trakia Agricultural Research Institute, Edirne experimental area, during 2013-2015 cropping years. Grain yield, days of heading, plant height, 1000-kernel weight, test weight, protein ratio, leaf rust, stripe rust, Septoria leaf spot and relationship among these parameters were investigated. Based on a two years data, apart from protein content, other parameters showed significant difference (p<0.05). When compared to the mean yields in both cropping years, the genotypes Gelibolu and BBVD-3, BBVD-4, BBVD-9 genotypes were determined the better-adapted genotypes under target environment. Cultivar Aldane and TCI011322-8 line was detected as very tolerant to leaf rust and stripe rust in both years under the infection of field condition. Aldane had higher protein ratio, 1000-kernel weight and test weight. Grain yield was positively correlated with test weight and negatively correlated with foliar diseases. A highly significant negative correlation was determined between grain yield and plant height in both growing years. Leaf rust and Septoria tritici leaf disease had negative effect on protein ratio in both years. There was a significant positive relation between 1000-kernel weight and test weight. Results of the study indicated that based on biotic stress factors BBVD-6, BBVD-7 and TCI011322-8 are promising lines that need to be improved a bit further.
Effect of rations with fresh leaves of Gmelina arborea on growth performance and organ weights of rabbit bucks
Authors: Pius O. , Ahemen T. , Addass P.A.
Published: January 2020

Abstract. Thirty rabbit bucks of mixed breeds (New Zealand white x Chinchilla) with average live weight of 852g, aged between 12 and 14 weeks were subjected to a feeding trial for 14 weeks, to determine the effects of diets with different ratio concentrate to fresh leaves of Gmelina arborea (FLGA) on growth performance, relative carcass weight and relative organ weights of rabbit bucks. The rabbits were randomly allo- cated into five treatments: Treatment 1-T1 (100g concentrate /C/: 0g FLGA), Treatment 2-T2 (75g C: 25g FLGA), Treatment 3-T3 (50g C: 50g FLGA), Treatment 4-T4 (25g C: 75g FLGA) and Treatment 5-T5 (00g C: 100g FLGA). The results obtained in this study showed that all the growth performance parameters and relative carcass weights differed significantly (P<0.05) across treatments. Apart from relative liver and lungs weights, which differed significantly (P<0.05) across treatments, other viscera organs were not affected by the dietary treatments. The results revealed that rabbit bucks in T2 and T3 performed better, rabbits in T4 performed the least, while rabbit bucks in T5 could not survive beyond two weeks. Concentrate to FLGA at the ratios of 75g C: 25 FLGA (T2) and 50g C: 50g FLGA (T3) are therefore, recommended as the best combinations for rabbit breeding bucks.
Induction and recovery from anaesthesia in fry of European catfish (Silurus glanis L.) exposed to clove oil
Authors: Krasteva V. , Zaikov A.
Published: January 2020

Abstract. The purpose of the study is to establish the efficacy of different concentrations of clove oil and the time needed for induction and recovery from anesthesia of European catfish (Silurus glanis L.) fry. The experiment was carried out in laboratory conditions with 50 specimens with body weight 1.11±0.25g and body length 5.45±0.60cm. For the aim of this paper the following five concentrations of clove oil are used: 0.01 ml.l-1, 0.02 ml.l-1, 0.03 ml.l-1, 0.04 ml.l-1 and 0.05 ml.l-1. At the lowest concentration (0.01ml.l-1) the effect is sedative and the fry do not reach the phase of complete immobilization. The application of 0.02 ml.l-1 concentration of clove oil is not beneficial for practical usage, with only 30% of the fish reaching phase 4 of anesthesia. At the highest concentrations (0.04 ml.l-1 and 0.05 ml.l-1) all of the fry were anesthetized for a short time, but the process of recovery was not successful for all of the fry. All of the fry reach phase of anesthesia and recovery without loses at 0.03 ml.l-1. This concentration is advisable for anesthesia of European catfish fry during different manipulations.

Published: January 2020

BACKGROUND: The discovery of a cluster of short non-coding RNAs called microRNAs (miRNAs) has become an important event in molecular biology. One of its representatives, miR-122 plays a large role in regulating the expression of genes involved in carbohydrate, lipid metabolism, and iron metabolism in the body. In experimental studies it was shown that in addition to regulatory functions, miR-122 is involved in the pathogenesis of hepatitis C, providing the life cycle of the virus in the cell. The shift of emphasis in the study of miR-122 from basic research into clinical medicine seems to be a promising area of personalized medicine.
AIMS: to determine the clinical significance of miR-122 in acute and chronic hepatitis C and associated hepatocellular carcinoma.
MATERIALS AND METHODS: A total of 407 people were examined, including 17 patients with acute hepatitis C (AHC), 158 patients with chronic hepatitis C (CHC) and 62 patients with HCC associated with hepatitis C. Comparison groups consisted of 84 healthy individuals and 62 patients with clinically pronounced cirrhosis of a non-infectious etiology. In each cohort, the relative miR-122 level was determined in the blood of patients. The analysis was performed in PCR using the Qubit microRNA Assay Kit -100 for the quantitative determination of microRNAs (Thermo Fisher Scientific, USA). Relative miR-122 expression values were calculated by the formula 2 -CT using U6 snRNA as a reference RNA.
RESULTS: The highest miR-122 level in serum was found in patients with AHC at the height of the icteric period. The level of miR-122 showed a direct correlation with the activity of hepatic transaminases in patients with AHC (r = 0.72) and CHC (r = 0.44). An analysis of miR-122 level relative to the degree of liver fibrosis in patients with chronic hepatitis C showed that, as liver fibrosis progresses, the level of miR-122 expression decreases. The decrease in miR-122 expression in patients with severe fibrosis was universal and did not depend on the etiology of the disease. The development of HCC in the presence of chronic hepatitis C was accompanied by a decrease in the level of miR-122 by 10 times on average compared to patients with chronic hepatitis C.
CONCLUSIONS: The determination of the expression level of miR-122 in serum can be used in laboratory monitoring of the management of patients with HC as an indicator of the severity of liver damage in AHC and the rate of formation of liver fibrosis in CHC. Evaluation of possibility of using miR-122 as a predictor of the development of HCC in the outcome of HC requires additional studies of the specificity and sensitivity of the test and comparison of the obtained data with the results of using generally accepted protein tumor markers.
Truly Autonomous Machines Are Ethical
Authors: Hooker John , Kim Tae Wan
Published: January 2020

There is widespread concern that as machines move toward greater autonomy, they may become a law unto themselves and turn against us. Yet the threat lies more in how we conceive of an autonomous machine rather than the machine itself. We tend to see an autonomous agent as one that sets its own agenda, free from external constraints, including ethical constraints. A deeper and more adequate understanding of autonomy has evolved in the philosophical literature, specifically in deontological ethics. It teaches that ethics is an internal, not an external, constraint on autonomy, and that a truly autonomous agent must be ethical. It tells us how we can protect ourselves from smart machines by making sure they are truly autonomous rather than simply beyond human control.

Monopolies and perfect competition in Solow–Uzawa’s general equilibrium growth model
Authors: Zhang Wei-Bin
Published: January 2020

The purpose of this study is to introduce monopolies to neoclassical growth theory. This unique contribution attempts to make neoclassical economic growth theory more realistic in modelling the complexity of economic growth and development with different types of market structures. This study is based on a few well-established economic theories in the literature of economics. We frame the model on basis of the Solow–Uzawa two-sector growth model. The modelling of monopoly is based on well-developed monopoly theory. We model behavior of the household with Zhang’s concept of disposable income and utility function. The model endogenously determines profits of monopolies which are equally distributed among the homogeneous population. We build the model and then identify the existence of an equilibrium point by simulation. We conduct comparative static analyses in some parameters.
Ensuring sustainable innovative development of the metallurgical complex enterprises
Authors: Shtansky V. A.
Published: January 2020

It is shown that the most important factors determining the sustainable innovative development of the metallurgical complex are the availability of competitive metal production capacities with the systematic demand for Russian metal products both in the domestic and foreign markets. It was determined that as a result of the implementation of major investment programs by leading metallurgical companies implemented in the iron and steel industry of Russia, production capacities have been created competitive types product of in the world market. However the realization of this potential is sharply limited due to the insufficient development of the engineering complex As a result, there was a significant gap between the large production and economic potential of Russian metallurgical companies created over the years of favorable economic conditions and the limited opportunities to use this potential. Various measures for the development of metal-consuming industries have been substantiated, including the maximum possible expansion of sources of financing, both through state support and by attracting private investment, largely through public-private partnerships.
“La época de los esclavos se acabó”: género y condiciones de trabajo en las empresas de limpieza en Argentina
Authors: Capogrossi Lorena
Published: January 2020

Esta investigación parte de una serie de interrogantes acerca de las características del trabajo de las mujeres que se desempeñan en empresas de limpieza no doméstica en Córdoba, Argentina. El abordaje del problema se realiza desde una perspectiva teórico-metodológica cualitativa que recurre a los instrumentos proporcionados por la etnografía. De este modo, tanto la observación y registros de campo, como la realización de entrevistas semiestructuradas con cuestionarios flexibles, permitieron reunir un corpus de información sistematizada en este artículo. Se seleccionaron dos aspectos: por un lado, el universo que envuelve las condiciones de trabajo de las operarias del sector, incluyendo formas de contratación, salarios, los tipos de tareas que realizan y la alta rotatividad entre lugares de trabajo; por otro lado, el análisis sobre algunos procesos de disciplinamiento que se ponen en movimiento en estos espacios. Las dimensiones analizadas posibilitan caracterizar al sector como una opción preferible a otro tipo de tareas, como por ejemplo el trabajo doméstico remunerado, porque la relación de dependencia con estas empresas otorga cierta formalidad que no existía anteriormente en las trayectorias laborales de las mujeres entrevistadas. Sin embargo, las condiciones de trabajo en las que deben desempeñarse se construyen sobre un marco de derechos vulnerados y relaciones jerárquicas.
La independencia del banco central y su papel en el dominio del capital financiero sobre el Estado
Authors: Pierre-Manigat Matari
Published: January 2020

El presente trabajo analiza –a un nivel teórico– el papel de la independencia del banco central en las relaciones entre el capital financiero y el Estado. Para ello, se considera la naturaleza dual del banco central: institución pública, por un lado, y representante de la clase financiera, por el otro. La dualidad determina el lugar del banco en la máquina de Estado, así como sus relaciones con la Hacienda pública (o Tesoro). A partir de un enfoque metodológico que combina la economía y la sociología política, se muestra cómo los lazos entre el banco central y la Hacienda pública conforman lo que se designa como estructura organizacional del Estado. Su caracterización es decisiva para analizar el papel del Estado en la reproducción de un régimen de acumulación. Las “grandes crisis” –o crisis de régimen de acumulación– determinan los cambios fundamentales en la estructura organizacional del Estado. La independencia del banco central se convirtió en la piedra de toque de la reconfiguración de esta estructura en el capitalismo de hoy. De ahí la principal conclusión de este trabajo: la estructura organizacional asociada con la independencia del banco central opera como correa de transmisión de la dominación financiera en el Estado y en el campo político contemporáneo.
Desde la amenaza natural al desastre: una construcción histórica del terremoto y tsunami de 1960 en Saavedra
Authors: Inostroza-Matus Cristian Ceferino , Molina-Camacho Francisco , Romero-Toledo Hugo
Published: January 2020

Los desastres constituyen fenómenos complejos, se trata del resultado de procesos socioambientales y territoriales donde se entrelaza y reconfigura la naturaleza y la sociedad. Pese al innegable rol de la naturaleza en la construcción y generación de desastres, estos son fuertemente condicionados por procesos históricos de acumulación de vulnerabilidad sobre ciertas poblaciones, donde el componente étnico y racial ha tenido un carácter central a la hora de determinar quiénes son más afectados. El desastre de 1960 en la comuna de Saavedra (Chile) es ejemplo empírico de esto, aquí los impactos y destrucción causada por el terremoto más grande registrado en la historia y su tsunami no solo responden a la extraordinaria magnitud del fenómeno, sino que son resultado de un proceso de construcción histórica del territorio. El artículo analiza este desastre desde una geografía histórica y crítica, buscando exponer cómo se transforma el territorio y su población, generando las condiciones necesarias para que se produzca el desastre. Así, por medio de la revisión de textos de exploradores, informes militares, mapas, autobiografías, investigaciones científicas, visitas al terreno y la ayuda de sistemas de información geográfica, se busca reconstruir el proceso de conformación del territorio de Saavedra, revelando la relación directa que existe entre la invasión del territorio mapuche lafkenche por parte del Estado de Chile y el mayor desastre de su historia más de un siglo después.
A argumentação contrária aos Direitos Humanos em comentários em portais de informação: um olhar sobre a questão prisional
Authors: Brito Clebson Luiz de
Published: January 2020

RESUMO:Parte de um trabalho mais amplo dedicado às representações discursivas sobre os Direitos Humanos, o presente artigo examina a argumentação contrária a esses direitos em comentários relativos a notícias sobre a questão prisional em portais de informação. Para isso, diferentes comentários foram coletados nos portais: G1, UOl e Terra, que são considerados os mais abrangentes, e posteriormente foram analisados a partir de uma abordagem teórica derivada da interação entre os estudos do discurso e os estudos da argumentação. O exame realizado revela, em última análise, procedimentos argumentativos que configuram uma espécie de retórica duplamente desumanizante, na medida em que os textos, atribuindo em geral ao outro uma condição não humana, se valem disso para sustentar ideias e incentivar ações típicas de pessoas embrutecidas por relações sociais violentas.

PALAVRAS-CHAVE: Direitos Humanos; argumentação; questão prisional; comentários em portais de informação.

 

ABSTRACT:Part of a broader work dedicated to the discursive representations about Human Rights, this article examines the argumentation contrary to these rights in comments, related to news about the prison issue, in news websites. To do that, different comments were collected in the websites: G1, UOl and Terra, which are considered the most comprehensive ones, and these texts were subsequently analyzed based on a theoretical framework derived from the interaction between discourse studies and argumentation studies. The examination reveals, ultimately, argumentative procedures that constitute a double dehumanizing rhetoric, since the texts, generally attributing to the other a non-human condition, use this to support ideas and encourageactions typical of people brutalized by violent social relations.

RESUMO:Este artigo visa identificar a dinâmica de interação de comunidades globais de RecursosEducacionais Abertos (REA) na rede social Twitterno período de2012 a 2017. Buscamos evidenciar, por meio da Análise de Redes Sociais (SCOTT, 2012; RECUERO, 2014), os nós mais bem posicionados e que servem como pontes para troca de informação entre comunidades centrais e periféricas dentro da rede de REA. Para isso, foram produzidos três grafos a partir de métricas de centralidade de intermediação, de grau de entrada e de saída. Os resultados revelaram cinco pontes e sete grandes comunidades que se destacam nas interações dentro da rede. As cinco pontes são fundamentais na manutenção do fluxo de informação que parte das sete comunidades principais para regiões mais periféricas do circuito de REA. Seis comunidades e quatro pontes estão localizadas no Norte Global e uma comunidade e uma ponte encontram-se no Sul Global.

ABSTRACT:This article aims at identifying the interaction dynamics of Open Educational Resources (OER) global communities on Twitter, from 2012 to 2017. Our purpose is to identify, by using Analysis of Social Networks (SCOTT, 2012; RECUERO, 2014), the best positioned nodes that serve as bridges for information exchange among central and peripheral OER communities within the network. Three graphs based on metrics of betweenness centrality, indegree and outdegree centralityare produced. The results show that five bridges and seven large communities prevail in interactions within the network. The five bridges are fundamental in maintaining the flow of information that emanates from the seven communities to more peripheral regions of the OER circuit. Six communities and four bridges are located in Global North and one community and one bridge are based in the Global South.

Published: January 2020

Involvement of oral cavity in lepromatous leprosy has been observed in 19-60% cases and has been described as late manifestation of disease. About 75% of oral lesions have been observed in the anterior part of hard palate which may result in debilitating complications like perforation of hard palate. We present a case of lepromatous perforation of hard palate that was effectively treated by multidrug therapy for the primary disease. The patient was declared disease free by slit skin smear method and reparative surgery of perforation was done with good results.
Revitalisasi hukum waris Islam dalam penyelesaian kasus sengketa tanah waris pada masyarakat Sasak

Published: January 2020

The inheritance issue is considered crucial to evaluate since it is closely related to inheritance transfer from the deceased to the living family and death is natural and common phenomenon. This research aims to investigate the inheritance legal system, the factors influencing the land dispute cases and the revitalization of Islamic legal system to reach a settlement of this land dispute issues. This field research employs qualitative approach using field and library research with socio-legal approach. The research data is categorized into two, primary and secondary data. The data was obtained using observation technique, interview, and doccumentation. The results indicate that: First, the distribution of inheritance land is conducted in different ways such as grants,, discussion, and faraid. Second, the factors influencing the land dispute cases are greed and lack of information about inheritance legal system, so the society do not know the legal system related to the inheritance. Third, revitalization is important because it is ruled out in Islamic teachings and is considered absolute for Islam society. This research conludes that Islamic Inheritance legal system is the best alternative to reach a settlement of land disputes in Sasak community.
Hydrophobic nature of mammalian ceramide glycanases: purified from rabbit and rat mammary tissues.
Authors: Basu M , Dastgheib S , Girzadas M A , O'Donnell P H , Westervelt C W , Li Z , Inokuchi J , Basu S
Published: January 2020

The ceramide glycanase (CGase) activities, which cleave the intact oligosaccharide chain and the ceramide moiety of a glycosphingolipid, have been characterized from two mammalian sources. The enzymatic activities are almost comparable in rabbit and rat mammary tissues. The majority of the activities has been concentrated in the soluble fraction which could be partially purified using hydrophobic columns. The rabbit mammary ceramide glycanase activity has been purified up to 1438-fold using ion exchange and hydrophobic columns in tandem. The purified protein exhibited a molecular mass of 54 kDa which could be immunostained on the Western blot with clam anti-CGase polyclonal antibody. In addition, a 98 kDa protein also exhibited positive immunostain in a successive purified fraction with that antibody and is under investigation. The requirement for the optimal enzymatic activities are similar for both rabbit and rat CGase activities. The CGase activity requires the presence of detergent for optimal activity but is not dependent on the presence of any divalent cations. However, Hg2+, Zn2+, and Cu2+ are inhibitory to the enzymatic activities. It has been observed that rat as well as rabbit CGases are inhibited by both D- and L-PDMP (1-phenyl-2-decanoylamino-3-morpholino-1-propanol.HCl) and its higher analogue PPMP (1-phenyl-2-palmitoylamino-3-morpholino-1-propanol.HCl). Alkyl amines containing C12 and higher chains are also found to inhibit both rat and rabbit CGase activities. Substantial levels of CGase activities have also been observed in various human tumor cells as well as in developing avian brains. These observations are significant in view of the recent findings that ceramide, which is one of the enzymatic reaction products of CGase activity, is mediating different cellular events like signal transduction and apoptosis. The role of this enzyme in development, metastasis and cellular regulation are anticipated.

Reactive oxygen species can cause extensive DNA modifications including modified bases. Some of the DNA base damage has been found to possess premutagenic properties. Therefore, if not repaired, it can contribute to carcinogenesis. We have found elevated amounts of modified bases in cancerous and precancerous tissues as compared with normal tissues. Most of the agents used in anticancer therapy are paradoxically responsible for induction of secondary malignancies and some of them may generate free radicals. The results of our experiments provide evidence that exposure of cancer patients to therapeutic doses of ionizing radiation and anticancer drugs causes base modifications in genomic DNA of lymphocytes. Some of these base damages could lead to mutagenesis in critical genes and ultimately to secondary cancers such as leukemias. This may point to an important role of oxidative base damage in cancer initiation. Alternatively, the increased level of the modified base products may contribute to genetic instability and metastatic potential of tumor cells.
Wyrau’haw: a Festa da Menina-Moça do povo indígena Tenetehara/Guajajara
Authors: Amorim Oliveira Ana Caroline
Published: January 2020

Este é um ensaio fotográfico a respeito da Wyrau’haw conhecida como Festa da Menina Moça ou Festa do Moqueado. É um ritual do povo Tenetehara/ Guajajara, de língua Tupi, localizados na pré-Amazônia maranhense. Esta festa marca a passagem da infância para a vida adulta da mulher Tenetehara/Guajajara. Ela é composta por três momentos: Mandiocaba ou Festa da Mandiocaba, Caçada e Festa do Moqueado. (GOMES, 2018). O presente ensaio refere-se a última etapa dessa festa, a Festa do Moqueado, que ocorreu em setembro de 2016, na aldeia Lagoa Quieta, Terra Indígena Araribóia. Os Tenetehara chamam de Wyrau’haw o momento da passagem e de transformação, da menina Tenetehara para a idade adulta. Em português eles usam a palavra “festa” para se referir a esse momento de relação entre os vivos e os encantados. Os Tenetehara conheceram as festas e como realizá-las com os encantados. As festas marcam uma comunicação entre os planos empíricos e o plano dos encantados. Como afirma Renato Sztutman(1998, p. 124) sobre o sentido que a festa possui entre os Waiãpi, povo Tupi da região amazônica: “É a atividade ritual -a festa- a instância capaz de colocar em prática este processo de transformação, essa incessante necessidade de transpor o plano das relações empíricas à comunicação com outros planos”.

Genethliacon for Barbara Bogołębska, or on the Need to Celebrate Birthdays and Anniversaries
Authors: Gaj Beata
Published: January 2020

The most popular Polish dictionaries of literary terms, which offer the definitions of even long lost and extremely particular genres such as Indian or Japanese drama, lack even the basic information on the genre which has existed in European literature (and even outside it) for the last 23 centuries. Genethliacon is a genre which has existed since the times of Callimachus (3rd c. BC), which has been used to celebrate a person’s birth or the anniversary of their birth. Genethliacons may be of a lyrical, dramatic or rhetorical nature, and are still practised today in various languages of the world (in Latin, in line with the ancient tradition). This article provides an outline of the development of the genre within the European tradition. Initial birthday songs, usually connoting Apollo, linked people with light and poetry. What is particularly interesting is that the basic characteristics of genethliacon’s genes have not undergo any major changes throughout the many ages. The celebration of one’s birth, anniversaries and other jubilees still entails wishes, and gift-giving, including poetry developed for the occasion. It may be worthwhile to preserve such a beautiful tradition by giving someone an originally composed genethliacon, e.g. Genetliacon Barbarae Bogołębskae dedicatum.
The Interview at the Beginning of Its History. Changes in the Implementations of the Genre
Authors: Kita Małgorzata
Published: January 2020

The interview as a journalistic genre formed in the first half of the 19th century. The author of the article studies how interviews developed in the first century of its existence. As the material basis I use the anthology: Wywiady prasowe wszech czasów originally edited by C. Silvester as The Penguin Book of Interviews. The genological analysis indicates that even at the beginning of the genre, interviewers selected as interviewees persons who had something to say about a certain topic. In terms of the structure of the interview, one might conclude that the first instances had the shape and form of a dialogue of two persons of specific pragmatic qualities: a journalist and the person with whom a conservation was considered worthy of publishing in a newspaper. Somewhat along that form, there emerged interviews which included narration, similar in form to the report. The author discusses the reasons for the similarities between the interview and the report.

Investigation of moral maturity and tolerance trends of primary school students in terms of various variables
Authors: Sengun Gokhan
Published: January 2020

Recently, morality and tolerance are among the most important concepts of education. The upbringing of morally mature children as tolerant individuals is a vital factor for individuals to develop a relationship. Moral maturity refers to the state of being competent in terms of moral emotion, thought, judgement, attitude and behaviour. A total of 43 boys and 151 girls from Altindag district of Ankara formed a sample group of 194 children. Personal Information Form, Moral Maturity Scale and Tolerance Tendency Scale were used in this study. The results revealed that according to the gender of the students, it is seen that there is a difference in tolerance acceptance, tolerance value and tolerance empathy levels. It is seen that girlsâ€™ acceptance and tolerance empathy levels are higher than boys. It is seen that there is a difference in tolerance empathy levels according to the educational level of parents. It is seen that there is a difference in tolerance empathy and tolerance acceptance levels according to the working status of parents of students. According to the monthly income level of studentsâ€™ families, there was no significant difference between moral maturity, tolerance empathy, tolerance value and tolerance acceptance levels. This is thought to be due to the fact that most of the parents have a similar income level. According to the number of siblings of students, there was a significant difference in tolerance empathy and tolerance value levels. It was found that there was a relationship between studentsâ€™ level of moral maturity and tolerance acceptance level. It was found that there is a relationship between tolerance empathy, tolerance acceptance level and tolerance value of students.

Keywords: Moral maturity, tolerance.
