Face-to-face and Computer-mediated Peer Review in EFL Writing
Authors: Ho Mei-ching , Savignon Sandra
Published: December 2017

This paper examines the use of face-to-face peer review (FFPR) and computer-mediated peer review (CMPR) in an Asian English-as-a-foreign-language (EFL) academic writing context. The participants were 33 English majors from a university of science and technology in Taiwan, a new type of school offering 2-year associate degree programs in foreign language studies. Our study contributes to the research on foreign-language-writing collaboration for Chinese learners in two important ways. First, many investigations of FFPR have looked at Chinese learners either in English as a second language (ESL) settings or at 4-year universities. Few have considered Chinese learners at 2-year colleges in EFL contexts. Second, there has been very little documentation of CMPR using annotation features in common word processing software in either ESL or EFL settings (Honeycutt, 2001). This study investigates the attitudes of 2-year college students in Taiwan toward the use of FFPR and CMPR in composition classes. Pedagogical implications are also drawn.
Using the French Tutor Multimedia Package or a Textbook to Teach Two French Past Tense Verbs
Authors: Corbeil Giselle
Published: December 2017

This paper examines the difference in learning outcomes between two groups of students, one of which used the French Tutor, a multimedia package, and the other a textbook to learn the formation and use of two French past tense verbs: the perfect and the imperfect. Unlike the textbook, the French Tutor included visual effects, intelligent feedback, drag-and-drop exercises, a variety of exercises of graduated difficulty, and the game "Who wants to be a millionaire?" Both groups of students were administered a pre- and posttest on the formation and use of these two verb tenses. The French Tutor group performed significantly better than the textbook group. A questionnaire asking for comments on the effectiveness of the French Tutor software was also given to the French Tutor group. All students acknowledged that the French Tutor software helped them acquire a better understanding of these two tenses and reported that the features that contributed most to their understanding were the exercises and the "Who wants to be a millionaire?" game. Discussion of the results follows, and suggestions are made for further research.

Sport Transitions as Epiphanies
Authors: Griffiths Randall J. , Barton-Weston Heather M. , Walsh David W.
Published: December 2017

Sport managers design development systems with the intent of retaining and advancing athletes through that system (Green, 2005). Important to this basic goal is the participant’s transition from one sport context to another. Transition research has focused primarily on elite athlete’s adaptation to career transitions as they advance at the highest levels or retire from sport (Wylleman & Lavallee, 2004). This orientation places a priority on the external transitions between sport structures before the internal, cognitive development of the athlete. This study examined the transitions of sport participants from an interpretive framework with the goal of understanding the individual’s experience of transition without it necessarily being linked to a typical external change. The sport stories of 48 students at a mid-sized, private university were collected and analyzed utilizing an interpretive paradigm. The disruption stage of these stories represents a time of crisis and transition. Denzin (2001) provided a typology for moments of crisis through four types of epiphanies: major, cumulative, illuminative, and relived. Using this typology of epiphanies can help sport managers to understand these transition events within the life of the participant. Analysis resulted in all disruptions being coded into one of the four original epiphany types. However, a large number of stories were categorized as major epiphanies. Further inductive coding yielded three sub-types of major epiphanies: major bodily, major life change, and major success. The stories within each type or subtype contained similarities in the speed of transition and the breadth of impact of the transition event. For example, stories of major bodily epiphany shared the immediate, life altering impact of significant injury while stories of cumulative shared the slow realization that the sport context had changed without the participant’s realization. Sport managers will be able to use the results of this study to understand and accommodate the pace and breadth of transition experienced by participants in their sport development systems thus maximizing the retention and advancement to the elite ranks.

Paraffin embedding, microtomy and fluorescence in situ hybridization (FISH) of whole adult Drosophila v1
Authors: Elya Carolyn , Martinez Ciera
Published: December 2017

Paraffin embedding and sectioning is a classic technique used in a variety of biological disciplines. Though the fruit fly Drosophila melanogaster are one of the most commonly-employed model organisms, the immense Drosophila literature is lacking in current protocols for sectioning whole, adult flies. Here, we adopted a plant histology protocol to embed entire adult flies for thin sectioning and present our protocol for performing FISH on the subsequent sections. In the interest of reproducibility, we have tried to include details that are normally omitted from published protocols.

Authors: Araujo Juliano Augusto Orsi , Ribeiro Maisa Souza
Published: December 2017

Objetivo: Investigamos a produção bibliográfica sobre remuneração de executivos nos cenários brasileiro e internacional, a fim de formar uma base teórica para o desenvolvimento de pesquisas empíricas que envolvam o tema. Elegemos a pesquisa de Jensen e Murphy (1990) como marco inicial das discussões sobre a temática.

Método: Trata-se de uma revisão de literatura. A pesquisa foi elaborada com buscas de palavras chave, através da ferramenta EndNote™ e o SPELL – Scientific Periodicals Electronic Library, mantido no Brasil pela ANPAD (Associação Nacional de Pós Graduação e Pesquisa em Administração) sendo: i) Executive Compensation; ii) CEO Compensation; iii) Company performance combinada com a palavra Compensation e os termos correspondentes em português na base brasileira.

Resultados: Os principais estudos publicados concentram-se nos cenários norte americano e britânico, com destaque para os professores Michael C. Jensen (Harvard University), Kevin M. Murphy (University of Southern California) e Martin J. Conyon (University of Pennsylvania). Jensen participou do estudo que marcou a discussão do problema de agência (Jensen & Meckling, 1976). Murphy desenvolve pesquisas sobre a temática a partir dos anos 1980, no cenário norte americano, período que também marca o início dos estudos de Conyon, porém, no cenário britânico. Os três autores são referência no tema e desenvolvem estudos em outros cenários econômicos, tais como Canadá, Alemanha e mais recentemente China.

Contribuições: Os achados aqui trazidos contribuem para o desenvolvimento de novas pesquisas, de caráter empírico, principalmente em países em que a temática se encontra em desenvolvimento ou em regiões em que surja o interesse pelo assunto, com o incremento destas variáveis para contribuir com o entendimento do problema de agência.
Mapa Conceitual da Fraude: Configuração Teórica e Empírica dos Estudos Internacionais e Oportunidades de Pesquisas Futuras
Authors: Maragno Lucas Martins Dias , Borba José Alonso
Published: December 2017

Objetivo: Explicar o fenômeno da fraude pela construção de um mapa conceitual e sintetizar os diversos tipos de fraudes.

Método: O estudo realizou uma revisão de literatura, por meio nos trabalhos teóricos e uma síntese de pesquisa, referente aos trabalhos empíricos.

Resultados: A revisão de literatura construída permitiu identificar que a Teoria do Triângulo da Fraude teve sua origem a partir do crime de colarinho branco. Os elementos da teoria (oportunidade, motivação e racionalização) evoluíram desde 1950 e recentemente são criticados, pois descobertas têm sido feitas que modificam o entendimento dos motivos ex ante. Principalmente, demonstram evidências de que o elemento racionalização (a parte cognitiva) é limitado e ainda não está claro na literatura. Além disso o trabalho traz as revistas e autores mais profícuos da temática das fraudes.

Contribuições: As evidências desta pesquisa demonstram a interdisciplinaridade do tema e apontam oportunidades de pesquisas. Este trabalho contribui, também, para as pesquisas de prevenção e detecção da fraude, pelo entendimento dos motivos que levam indivíduos a tais atos criminosos ou desvios de conduta.

SEQUELAS DENTAIS APÓS TRAUMATISMO NA DENTIÇÃO DECÍDUA: RELATO DE CASO
Authors: Melo Priscila Thurler de , Reis Isabelly da Costa , Guimarães Gabriela Gomes , Rey Ana Cristina Fernandez , Alexandria Adilis Kalina , Soares Thais Rodrigues Campos
Published: December 2017

Os traumatismos na dentição decídua são rotineiros na clínica odontológica, o que exige do profissional grande habilidade e critério na abordagem do paciente e seus familiares. Traumas na dentição decídua podem acarretar sequelas nos dentes decíduos, bem como nos sucessores permanentes em desenvolvimento, uma vez que existe íntima relação anatômica entre os ápices dos decíduos e os germes dos permanentes. O objetivo deste trabalho foi apresentar as sequelas dentais após traumatismo na dentição decídua, em um paciente sem acompanhamento odontológico. Paciente do gênero masculino, dez anos de idade, compareceu à clínica de odontopediatria da Universo, sem queixa. Durante o exame clínico foi observada alteração de cor e retenção prolongada do elemento 51 ocasionando desvio de erupção do sucessor permanente e, consequentemente, mordida cruzada anterior. Durante a anamnese, os responsáveis confirmaram a história de trauma no elemento 51 aos cinco anos de idade, porém não se recordam como e local do acidente. Os mesmos não relataram nenhum atendimento odontológico após o traumatismo dentário. Após avaliação e exame radiográfico foi realizada a exodontia do elemento decíduo e encaminhamento do paciente para tratamento ortodôntico, onde foi confeccionado um plano inclinado fixo para reposicionar o sucessor permanente. Conclui-se que, segundo o caso apresentado, o traumatismo gerou sequelas no próprio dente decíduo acometido, assim como no sucessor permanente. Além disso, a ausência de tratamento e acompanhamento do caso de traumatismo pode ter contribuído para o desvio de erupção na dentição permanente. Após tratamento adequado foi possível a correção da mordida cruzada anterior com sucesso clínico do caso.

A radioterapia no paciente com câncer de cabeça e pescoço pode resultar em muitas consequências negativas, como a hipossalivação. Sem a proteção da saliva há um risco aumentado de cáries e doenças periodontais que podem causar a perda dentária e consequentemente influenciam no impacto da saúde bucal na qualidade de vida. O objetivo desse estudo foi avaliar o impacto da saúde bucal na qualidade de vida dos pacientes pós-radioterapia de câncer de cabeça e pescoço por meio das avaliações de fluxo salivar e edentulismo. A amostra foi composta por 19 indivíduos com idade a partir de 18 anos e diagnóstico de câncer de cabeça e pescoço. A radioterapia do tipo Intensidade Modulada (IMRT) foi o tratamento mais realizado 16 (68,4%). Referente ao tempo pós-radioterapia, nove (47,4%) haviam terminado o tratamento há um ano. Quanto ao impacto da saúde bucal na qualidade de vida, 15 (79,9%) apresentaram algum impacto. O maior número de pacientes sete (36,8 %) não usava algum tipo de prótese e nove (47,4%) necessitavam de uma combinação de reabilitações. Encontraram-se 15 (78,9%) pacientes com fluxo salivar classificado como muito baixo e quatro (21,1 %) mostraram melhor fluxo salivar após cinco anos da radioterapia. O teste de Coeficiente de Correlação de Pearson mostrou correlação entre a necessidade de prótese e a idade (p=0,006; r=0,4734) e a necessidade de prótese e o fluxo salivar dos pacientes (p=0,03; r=0,3672). As complicações da radioterapia em cabeça e pescoço acarreta uma série de consequências físicas e psicológicas. O tempo após a radioterapia parece influenciar em alguns casos a melhora do fluxo salivar e em menos de um ano de tratamento não há impacto da saúde bucal na qualidade de vida. São necessários estudos longitudinais com essa população para a verificação dos efeitos da radioterapia ao longo dos anos.

Entende-se por anomalia uma variação ou desvio de uma característica ou estrutura anatômica, relativamente à normalidade. Pelo tratamento antineoplásico, sobreviventes de câncer infantil estão em risco de adquirir anomalias dentárias como efeito tardio. Esses efeitos podem ser observados pela radiografia panorâmica. Para resultados confiáveis e reprodutíveis é necessário que os examinadores passem por um treinamento prévio. Este pode ser medido por meio de testes de concordância como o teste de Kappa. O objetivo do presente trabalho foi apresentar a importância da calibragem dos examinadores para avaliação radiográfica de anomalias dentárias de pacientes com câncer, a fim de obter informações com alta confiabilidade. Foram selecionadas aleatoriamente 40 radiografias panorâmicas digitais, sendo 20 do grupo controle e 20 do grupo experimental. Os examinadores foram considerados calibrados quando os valores do teste de Kappa estavam entre 0,61-1,0. A calibração intraexaminador teve como mínimo um valor de concordância substancial (0,61-0,80) e um máximo de concordância perfeita (0,81 -1,0) para os dois examinadores. Em relação à calibração interexaminador observou-se como resultado mínimo de Kappa uma concordância moderada (0,41 – 0,60) na primeira etapa, sendo que na segunda etapa chegou-se a uma concordância substancial (0,61-0,80) demostrando que as examinadoras se encontravam calibradas. Para a avaliação de anomalias dentárias em radiografias panorâmicas é necessária uma calibração cautelosa e minuciosa que favoreça a emissão de informações confiáveis e reproduzíveis para evidência científica.

Published: December 2017

Systemic lupus erythematosus in children (juvenile-onset SLE, jSLE) is a multisystemic disease with an unpredictable course and a more severe phenotype compared to adults. The patterns of jSLE are extremely heterogeneous, so an enrollment to controlled studies may be rather complicated. Due to this problem and some additional ones, there are no standards for treatment of jSLE yet. The attending physician is fully responsible for the induction and maintenance therapeutical options including durability and aggressiveness.

Objectives: finding of jSLE individual course’s features prognostically connected with the disease outcome.

Methods: 45 children admitted to the SPbGPMU hospital with the systemic lupus erythematosus diagnosed at the age of 4-17 years were enrolled in this retrospective study. Primary SLE manifestations, the activity of disease according to SELENA-SLEDAI and ECLAM scales during initial treatment period and flares after it, the fact of remission achievement in 6 months were evaluated in each patient.

Results: a few organ involvements were considered to be connected with outcome’s characteristics, for example lupus nephritis and early disease oncet are unfavorable predictive factors. The positive connection of favorable outcome with cyclophosphamide, intravenous methylprednisolone and mycophenolate mofetil was found; the negative connection between initial disease activity and flares after induction treatment was also noticed.

Conclusion: the patient with initially high disease activity treated aggressively with high cumulative doses of cyclophosphamide, intravenous methylprednisolone and mycophenolate mofetil has more chances of the favorable outcome (the achievement of remission without further flares).
Recurrent bronchitis as a clinical variant of functional changes of the respiratory system in children
Authors: Nesterenko Zoia V.
Published: December 2017

Background. The high prevalence of acute respiratory infections in children, recurrent episodes of acute bronchitis remain to be one of the hot topics of pediatrics. The causes of recurrent exacerbations of bronchitis in children, despite the numerous research works on this issue, are not completely clear.

Aim: to study the features of the clinic in children with recurrent bronchitis.

Methods. There were 58 patients aged 3 to 12 years with recurrent bronchitis. A study demonstrated the close relationship between recurrent episodes of acute bronchitis not only with pre-preschool and preschool age (when bronchopulmonary tissue is not completely differentiated), with the influence of negative environmental factors, with bacterial, viral infection, but also with signs of connective tissue disorders (CTD) in them.

Results. Revealing connective tissue insufficiency explains the causes of disorders of bronchial cartilage and connective tissue, that lead to the development of bronchial dyskinesia thus exacerbating the vulnerability of immature bronchopulmonary tissue along with autonomic dysfunction, typical for CTD. Involvement of several organs and systems in the CTD process changes the course of clinical symptoms of recurrent bronchitis. Probably by the main differentiation of tissues of organs at this age, including connective tissue, can be explained the fact that in 2/3 of the children observed by the age of 7 the manifestations of exacerbations of the disease ceased. In the half of the patients with recurrent episodes, who had bronchial obstruction in the first year of life, a allergy history, paroxysms of respiratory dyspnoea after an additional examination, – asthma was diagnosed; in one patient an aneurysm of the lung vessels was revealed.

Conclusions. Basing on the conducted study, the use of the term “recurrent bronchitis” is advisable in children of the first seven years of life. In patients with continuing episodes of bronchitis bronchopulmonary pathology should be excluded; in patients with allergy history and symptoms of bronchial obstruction, spasmodic cough in previous episodes of bronchitis asthma should be excluded. The presence of symptoms of connective tissue disorders in children with recurrent bronchitis requires a careful examination of patients for the detection of comorbid diseases.

Published: December 2017

Introduction. The deficiency of vitamins is a factor that has a negative impact on the growth and development of the child, it leads to a decrease in nonspecific resistance of the organism, a decrease in the adaptive potential, acts as a risk factor for the development of nutritional disorders, aggravates the process and makes it difficult to treat any disease.

The purpose of the study. Assessment of the vitamin status of children attending pre-school educational institution by means of non-invasive methods for urinary excretion of ascorbic acid and metabolites of B vitamins.

Materials and methods. 49 children (26 boys and 23 girls) aged 4 to 7 years living in Moscow region, and 51 children (26 boys and 25 girls) 2-7 years old living in Ekaterinburg were examined in 2015-16 years (winter-spring period). Сhildren received the main nutrition in kindergarten. In the evening time on weekdays children additionally received separate foods or ready meals at home, on weekends (2 of 7 days) children ate at home. The supply with vitamins C, B1, B2 and B6 was evaluated by its hour urinary excretion.

Results. The picture of vitamin status of children from different regions turned out to be almost identical. The lack of vitamin B2 was found in about one third of the children, vitamin B1 and B6 insufficiency took place significantly 2 fold more often (in 61.2-76.5%). Decreased vitamin C excretion took place in 34.7% of children from the Moscow region. Only every fifth child was provided with all studied vitamins. A significant number of children showed multivitamin deficiency. Children who received multivitamin supplements were better supplied with these micronutrients.

Conclusion. The results indicate the need for correction of multimicronutrient insufficiency in children by including in the diet of fortified food products, the use of baby specialized products enriched with micronutrients, and vitamin-mineral supplements intake.

Published: December 2017

The article presents results of diagnostics, surgical treatment and follow-up of patients with rare hereditary-conditioned forms of thyroid cancer – medullary thyroid carcinoma in content of multiple endocrine neoplasia syndrome. Particular attention is paid to the examination and tactics of treatment of children and adolescents with family genetically confirmed Sipple syndrome. The disease is diagnosed in 4 families. Syndrome of multiple endocrine neoplasia 2a type we found in 7 (0.024%) of 29,325 children and adult patients. All the children were from families in which one of the blood relatives suffered medullary thyroid cancer. The family nature of the disease was confirmed by molecular genetic studies that revealed mutations in C634 (T1900C) in the 11 exon of the RET gene. Only in 3 out of 7 cases thyroidectomy was prophylactic. Four children were fond foci of medullary carcinoma in the removed thyroid gland. In total, 22 operations were performed for the members of 4 families suffering from the family syndrome MEN-2a. The article shows that if a patient is diagnosed Sippl's syndrome, all his blood relatives need to be checked for the mutation of the RET gene to identify familial medullary thyroid cancer, adenomas of parathyroid glands and pheochromocytomas. Early removal of the thyroid gland (in children under the age of 5 years) prevents medullary cancer, and timely diagnosis and adequate surgical removal of neoplasms of parathyroid glands and adrenal glands ensure recovery of the patients. Closest relatives should be checked for the level of calcium and calcitonin, catecholamines, vanillylmandelic acid and metanephrine, ACTH, cancer-embryonic antigen.

Published: December 2017

Comparative evaluation of sexual development among adolescent girls whose mothers experienced and did not experience psychological trauma associated with life-threatening was conducted. The physiological features of sexual development in girls in the Republic of Dagestan, whose mothers experienced a high risk of terror threat in pregravidarum period were identified. It was determined that in pre-pubertal period the concentration of luteinizing and follicle-stimulating hormone in peripheral blood in girls whose mothers experienced stress associated with life-threatening was significantly higher than in girls of the control group. In prepubertal period in girls whose mothers experienced a vital stress, the earlier decrease in the activity of the adrenal cortex in the transition from prepuberty to puberty was observed. Girls whose mothers experienced a vital stress can be characterized by an earlier menarche, at the age of 10-12 the menarche occurred significantly more often than in the control group. The anthropometric data show an earlier maturation of these girls under the age of 12. In the prepubertal period the formation of breast and pubic hair growth were ahead of girls in the control group. Thus, girls whose mothers experienced vital stress are characterized by an earlier and at the same time disharmonious puberty. They are characterized by earlier menarche, delayed rhythm of the menstrual cycle and some changes in humoral regulation rhythm. Thus, it is vital the stress suffered by women before pregnancy causes changes in hormonal regulation in pregnancy that leads to long-term damage of physiological homeostasis of the offspring.

Published: December 2017

The article deals with the problem of early neonatal and infant mortality. It is pointed out that recent advances in emergency and intensive care therapy have provided decline in early neonatal and infant mortality. Hemodynamic disorders are reported to be associated with any severe pathology in patients of all age groups including newborns, significantly influence quality of life of patients having experienced a critical condition. Clinical manifestations of hemodynamic disorders in infants are not considered to be specific; they are critically delayed and are not timely recognized. The article describes peculiarities of the cardio-vascular system of newborns that are responsible for the necessity of thorough hemodynamic profile monitoring in order to provide detection of vital function alterations at the early stages, ensure timely onset of intensive therapy and its qualitative performance. Special attention is paid to current methods of determination of central hemodynamic parameters, which are stated to be divided into invasive and non-invasive. The paper also highlights some peculiarities of evaluation of hemodynamic findings using specific monitoring methods and factors influencing the outcome. The article specifies increased interest towards non-invasive monitoring tools of hemodynamic profile in recent years; their relevance is stated to be doubtless in both pediatric and neonatal practice. The main task of any monitoring procedure is reported to be hemodynamic findings analysis, “trend tracking” in the process of monitoring a patient and intensive therapy performance.
The regional anesthesia for surgical correction of the malformation of upper extremities in pediatric
Authors: Manokhina Julia A.
Published: December 2017

The article presents an analysis of the publications devoted to the problems of anesthesia to surgical procedures at the malformations of the upper extremity in children. The article reviews the questions of epidemiology, classification of upper extremity malformation, safety of anesthesia and the role of regional blockades in the structure of intraoperative and postoperative analgesia to surgical procedures at the malformations of the upper extremity in children. Children are more likely than adults to experience stress in the operating room and early postoperative period. Children are almost impossible to prepare psychologically for the upcoming anesthesia, surgical intervention, a sense of pain after it. Surgical correction of malformations of the upper limbs in children is characterized by multistage and high traumatism, which requires the search for adequate methods of anesthesia, capable of ensuring not only the absence of pain, but also the negative impact on the nervous system of little patients. The key to the application of regional anesthesia in young children is the need for sedation or general anesthesia. The use of ultrasound navigation and electrostimulation of peripheral nerves significantly increases the level of safety and success of their realization. At present, the questions about the duration of postoperative analgesia with the use of peripheral nerve blocks and the need for additional anesthesia in the early postoperative period have been little studied. The influence of the applied anesthesia technique on the state of young children in the postoperative period are requires further investigation.
Pobreza y celebridades del espectáculo: un debate del accionar internacional
Authors: Marín Aranguren Erli Margarita , Millares Abella Nedi Natalia
Published: December 2017

Este artículo muestra la incidencia de las celebridades del espectáculo, como agentes de la sociedad civil, para transformar la pobreza que se vive en el mundo, especialmente en los países del cuerno de África. Ellas juegan un rol protagónico en términos de sensibilización de la situación. Buscan que sus audiencias pasen a la acción. Si bien no es una estrategia de acción nueva, en este artículo se hace un recuento de cinco hitos globales, donde las campañas han tenido como reeditores sociales a estrellas del espectáculo que han trabajo de la mano con otras organizaciones de la sociedad civil o redes transnacionales. Para evidenciar el accionar de estos agentes, primero se abordan los referentes teóricos que acercarán al lector a la discusión planteada. Posteriormente, se hace un recuento lineal de las interacciones de las celebridades del espectáculo con las acciones de la lucha contra la pobreza, las cuales no solo han generado un cambio en las campañas, sino también en la narrativa del tema. Esto demuestra la eficacia para incidir en decisiones políticas que han posibilitado la reducción de la pobreza, debido a que el cambio de narrative ha permitido la vinculación de líderes políticos y de organizaciones internacionales. Finalmente, se presentan las conclusiones, las cuales no solo abordan lo positivo de este aporte, sino también aspectos como el mercado de la beneficencia, la superficialidad de la información que se genera y que no logra concientizar, y la doble moral del accionar de los Estados.

Solid and urban waste produced by the municipality of Meknes amounts to more than 185.103 tons annually. Since 2002 they have been transported to a landfill controlled, wild of an area of 23 hectares on the outskirts of the Commune. This discharge is unfortunately devoid of a leachate treatment device (brownish liquid effluent, produced under the combined action of rainwater and fermentation of buried waste). This study aims to make a physico-chemical characterization and evaluate the states mineral and organic of this leachate. It should be noted that this physicochemical characterization is arbitrary because this discharge will soon be equipped with a waste disposal and recovery center (CEV) using Evalixm as a treatment method. Since 2014, the company '' SUEZ ''Environment began to put in place under control this discharge. For the realization of this characterization, we carried out a series of sampling leachate from June 2014 to June 2015. During this period, the physico-chemical analyzes carried out on these samples, revealed: - low levels of nitrates (NO3 - max = 18,1 mg / L) and phosphates (PO4 3- max = 0,38mg / L) - high levels of ammonium (NH4 + max = 54,13 mg / L) and nitrites (NO 2 - , max = 27,67mg / L). This mineral concentration is translated by a high electrical conductivity which has reached a maximum value of 7.35 10 3 μS / cm. Organic pollution estimated by the pollutant load is important; the values of the Calculated DCO from 1205 to 9207 mg O2 / L with an average of 4808 mg O2 / L, those of DBO are between 53 and 386 mg O2/ L for an average of 157 mg O2 / L. The values of the ratio DBO5 / DCO oscillate between 0.01 and 0.08 with an average of 0.04. This which testifies to the anaerobic character that prevails at the level of the discharge and a probable contamination of the water table. The hydrogen variant (pH) between 6,42 and 8,99 is an annual average of 8,42 which shows that the leachate produced by the landfill is basic. The pH value shows a stagnation (8.42 and 8.23) from one year to the next, reflecting its stability and aging

The objective of this study is to assess the water river quality of the Lower Valley of Ouémé in Benin. Two river water sampling campaigns were carried out during low and high water. At each sampling campaign, eleven (11) sampling sites were selected and at each site four samples were taken, making a total of 44 water samples. Hydrogen potential, dissolved oxygen, suspended matter and turbidity were measured in situ. Fecal contamination germs such as total coliforms, thermotolerant coliforms, Escherichia coli and fecal enterococci were counted by the membrane filtration technique. The results of the physical analyzes reveal that the pH measured in the water samples conformed to the WHO standard except turbidity. The results of the bacteriological analyzes in 100 mL of water sample of the river reveal average bacterial loads in periods of low and high waters which vary respectively from 2.57.10 2 ± 451 CFU and 3.35.102 ± 459 CFU for total coliforms; 1.42.102 ± 315 CFU and 1.55.102 ± 251 for thermotolerant coliforms; 0,79.102 ± 216 CFU and 1.55.102 ± 251 for E. coli. The Enterococci are absent in the waters during these two periods. The high burden of these germs counted in the high water period may be due runoff phenomenon and unhygienic behavior observable in the study area.

Faced with the threat of overfishing in Africa, this study was initiated in the coastal zone of Côte d'Ivoire to understand the nutrients availability as function of variation in the depth of thermocline. Data from the ocean bank, World Ocean Atlas (WOA), were used in the ODV software during the twelve months of 2009 taken at 5.5°W/4.5°N (station coordinates). ODV software has allowed to make seasonal analysis, from vertical profiles and latitudinal analysis from the coast toward the sea through some parameters such as temperature, nitrate, phosphate and oxygen. The depth of thermocline, nitracline, phosphacline and oxycline was determined by the seasonal analysis. To evaluate the enrichment intensity of coast towards the sea, latitudinal analysis was investigated using the section profiles (1°S/5°N coordinates). The main results have shown not only the variation in the depth of the thermocline, but also the variation of nitracline, phosphacline and oxycline at different marine seasons. During the cold season, there was an ascent of the thermocline over the surface of water and a strong enrichment from the coast to the sea especially in August. While in hot season, the thermocline was lower and its stability has favoured the stratification of the water column, which prevents the enrichment of the oxygenated surface layer. Analysis of relationships shows that nutrient elements and oxygen change polynomially with temperature.

Purpose: To analyze the waste factors of rejected X-rays films. Methodology: Descriptive and analytical prospective study from 1 January to 30 June 2017 carried out in the department of radiology and medical imaging of the Campus University Hospital of Lomé in Togo. Results: 4912 patients had received 5630 radiographic incidences, including 3288 (58.4%) on the analogy and 2342 (41.5%) on the digital. The reject rate was 12.5%. The vast majority of the X-rays films, 682 (96.9%) were rejected by the radiographers themselves just after development. The resumption frequency ranged from one repeat (550 X-rays films, or 78%) to 4 repeats (8 X-rays films, or 1%). Almost all of the rejected films, 702 (99.7%) came from the analogical room. Chest X-ray was the incidence with more rejection in 33.9% followed by pelvic and lower limb incidences in 21% of cases. More than 2/3 of the rejected films, 473 (67.2%), came from the students' act. The causes of the rejection were mainly centering (25.5%), underexposure (20.17%) and overexposure (12.93). The financial loss caused by the scrap of X-rays films amounted to about 418800F CFA or 638.5 €. Conclusion: Strengthening communication between radiographers and radiologists is necessary to avoid unnecessary repeats of patient’s radiographs.
Investigating the Network Characteristics of Two Popular Web-Based Video Streaming Sites
Authors: Almatarneh Feras Mohammed
Published: December 2017

The determinants of the strategies to be employed by video streaming sites are application (mobile devices or web browsers) and container of the video application. They affect video streaming network characteristics, which is often the traffic flow, and its quality. It is against this background that studies on streaming strategies suggested the need to investigate and identify the relationship between buffer time, video stream protocol, packet speed and size, upload time, and waiting period, specifically to aid network administrative support in case of network traffic bottlenecks. In view of this, this study investigates the network characteristics of YouTube and Vimeo, using experimental methodology, and involving WireShark as network analyzer. Google Chrome and Firefox are the web browsers employed, while packet size, protocols, packet interval, TCP window size and accumulation ratio are the metrics. Short ON-OFF, Long ON-OFF, and No ON-OFF cycles are the three streaming strategies identified. It is further shown that both Vimeo and YouTube employ these strategies but the choice depends on the container of the video streamed.
Implementation of a Simulation Model for Optimizing the Traffic Flow from Arafat to Muzdalifah
Authors: Jamjoom Arwa
Published: December 2017

This project simulates the flow of pilgrims when they travel from Arafat to Muzdalifah. The system includes the roads network that connects Arafat to Muzdalifah, which is represented as a queuing system with different queue measurements that simulate reality. The system also includes different types of transportation, such as small and large buses and trains, all of which are represented as objects with different size and colors. All system objects carry specifications as their corresponding source system objects, and these specifications are based on data collected by the Ministry of Hajj. The primary objective of the system is to answer “what if” questions to support decision making to optimize Hajj traffic, which can be achieved by manipulating the system’s variables and then by observing the key performance indicators of the system. The system presents the experimental results as visual feedback alongside written reports with statistics and illustrations.

Authors: Sanchiz Emanuel , González Magalí , Aquino Nathalie , Cernuzzi Luca
Published: December 2017

Currently, a growing interest is being caused by mobile applications which have functions implemented in the cloud (MobileApps-FC). Improvements related to the portability of these applications among different platforms and different service providers are a critical need. Model Driven Development (MDD) constitutes one of the alternatives to address portability issues. This work presents a systematic mapping study that analyzes different proposals that apply MDD to the development of MobileApps-FC and that, at the same time, consider the improvement of the portability of such applications. Even though we have identified just a few studies related to our subject of interest, the validation experiences that are presented in them, encourage the adoption of MDD to address portability issues. However, further validation experiences that consider more complex cases in industrial environments will be required to justify the benefits of MDD in a substantial manner.

In the LINTI, New Information Technologies Research Laboratory at the Computer Science School, in the National University of La Plata, it is being developed a project that involves the integration of the repository, implemented using DSpace, with different tools and platforms used in academic tasks. Accessibility is a process that cuts across all software development stages, so when using a free software product it is important to evaluate it in order to correct faults if it´s necessary. This article describes a DSpace repository accessibility validation, using screen readers for manual test, automatic validation with software tools and experimental test with users with and without disabilities. The evaluation involves the proper basic functions and the implemented extensions. The original DSpace software was extended through the integration with different tools and platforms, such as Moodle LMS, the library management system called Meran, file management services like DropBox and GoogleDrive and the social network Facebook.  The tools used during accessibility evaluation were Examinator, Google ChromeVox and one entirely implemented in the LINTI, called SiMor. The experimental tests were made with blind and deaf persons, most of them college students. All the validation results are detailed using tables and graphs, where it can observe the measured values. It is also described the changes that was necessary to carry out in the repository to improve the user experience and ensure Web service accessibility.
