Authors: Alves Francisco Regis Vieira , Dias Marlene Alves 
Published: May 2019

O presente escrito aborda elementos de ordem teórico-conceitual, característicos de um design de investigação em Didática da Matemática, com o escopo de assinalar uma discussão e a possibilidade do ganho de conhecimentos didático-metodológicos acerca da Teoria do Resíduo. Dessa forma, tendo em vista extensa literatura, com influência da vertente de pesquisa francesa, descrevem-se com maior ênfase, as etapas de análise preliminar, análise a priori de uma Engenharia Didática - ED, com atenção especial dedicada à concepção e a modelização de duas situações-problema. Por intermédio de uma perspectiva afetada pela Teoria das Situações Didáticas – TSD, o trabalho aborda quatro etapas dialéticas, relativas ao planejamento teórico de uma experimentação, que promovem um debate científico envolvendo professor, alunos e um saber matemático específico, significado e mobilizado por intermédio da visualização (com o uso da tecnologia), e do entendimento tácito preliminar de determinadas propriedades fundamentais na Teoria dos Resíduos. Outrossim, o trabalho acentua o caráter epistemologicamente intrincado da referida teoria matemática, fato que justifica um olhar pormenorizado e cientificizado, proporcionado por uma proposta de ED.Palavras-chave: Engenharia Didática.

Análises Preliminares.AbstractThis writing deals with conceptual and theorical order elements, characteristic of a particular design of research in the Didactics of Mathematics, varygin between offering a discussion and the possibility of a gain of didactical and methodological knowledge of the Residue Theory. Thus, aiming at extensive literature, with the French research, the preliminary stages nominated preliminary and a priori analysis of a Didactical Engineering – DE are described with a greater emphasis, with especial attention dedicated to the design and modeling of two didactic situations. Thus through a perspective affected by the Theory of Didactic Situations – TDS, the present work addresses four dialectical steps, regarding the theorical planning related to experimentation, with the goal to promote a scientific debate involving the teacher, students and a specific mathematical knowledge, signified and mobilized through the visualization (with the using of technology) and a tacit understanding of certain fundamental properties in the Residue Theory. Furthermore, the work emphasizes the mathematical character of a epistemological complex theory, which justifies a careful and scientific look provided by the present ED proposal.Keywords: Didactic Engineering.

Busca-se atentar para a Análise da Produção Escrita e suas possibilidades como Estratégia de Ensino proposta tanto por Santos (2014) quanto por Viola dos Santos et al. (2014), este artigo tem como objetivo discutir entendimentos revelados por alunos, em uma atividade de Análise da Produção Escrita como fio condutor da aula, expressão proposta em Cardoso (2017). A investigação ocorreu em uma turma de 7º ano, cujo sujeitos da pesquisa foram 20 alunos com faixa etária entre 12 anos de um Colégio Estadual da Região Metropolitana de Londrina. A eles foram apresentadas produções escritas realizadas por alunos de uma turma da EJA, anos finais do Ensino Fundamental. Tais produções possibilitaram elaborar questionamentos, que vieram a compor um instrumento que se caracteriza, inicialmente, como uma tarefa. Como uma pesquisa de cunho qualitativo, os registros escritos deixados pelos sujeitos da pesquisa na tarefa possibilitaram encontrar alguns resultados. De modo geral, os alunos passaram a considerar apenas a produção resolvida por eles como correta, e tampouco se atentaram a observar que há diferentes formas de se resolver uma mesma questão. Esse fato fez com que atribuíssem novos significados para as resoluções. Por fim, conclui-se que esta proposta foi ao encontro das possibilidades reveladas por Viola dos Santos et al. (2014) e a certo ponto se distanciou dos resultados apresentados por Cardoso (2017). Palavras-chave: Educação Matemática. Avaliação. Análise da Produção Escrita. Aulas de Matemática. AbstractLooking at of Written Production Analysis and its possibilities as a Teaching Strategy proposed by both Santos (2014) and Viola dos Santos et al. (2014), this paper aims to discuss understandings revealed by students in an activity of Written Production Analysis as the thread leader of the lesson, expression proposed in Cardoso (2017). The research was carried out in a 7th grade class, whose subjects were 20 students aged 12 years from a state college in the metropolitan region of Londrina. They were presented with written productions made by students of an EJA class, final years of Elementary School. Such productions made it possible to elaborate questions that came to constitute an instrument that is characterized initially as a task. As a qualitative research, the written records left by the research subjects in the task made it possible to find some results. In general, students have come to consider only the production that they have determined to be correct, and they have not been careful to observe that there are different ways of solving the same question. This fact, led to the attribution of new meanings to resolutions. Finally, we conclude that the students, this proposal found with the possibilities revealed by Viola dos Santos et al. (2014) and distanced from the results presented by Cardoso (2017). Keywords: Mathematics Education. Evaluation. Written Production Analysis. Mathematics class.

Abstract
Background:
The ultrasound-guided proximal intercostal block (PICB) is performed at the proximal intercostal space (ICS) between the internal intercostal membrane (IIM) and the endothoracic fascia/parietal pleura (EFPP) complex. Injectate spread may follow several routes and allow for multilevel trunk analgesia. The goal of this study was to examine the anatomical spread of large-volume PICB injections and its relevance to breast surgery analgesia.
Methods:
Fifteen two-level PICBs were performed in ten soft-embalmed cadavers. Radiographic contrast mixed with methylene blue was injected at the 2nd(15ml) and 4th(25ml) ICS, respectively. Fluoroscopy and dissection were performed to examine the injectate spread. Additionally, the medical records of 12 patients who had PICB for breast surgery were reviewed for documented dermatomal levels of clinical hypoesthesia. The records of twelve matched patients who had the same operations without PICB were reviewed to compare analgesia and opioid consumption.
Results:
Median contrast/dye spread was 4(2-8) and 3(2-5) vertebral segments by fluoroscopy and dissection respectively. Dissection revealed injectate spread to the adjacent paravertebral space, T3 (60%) and T5 (27%), and cranio-caudal spread along the endothoracic fascia (80%). Clinically, the median documented area of hypoesthesia was 5(4-7) dermatomes with 100% and 92% of the injections covering adjacent T3 and T5 dermatomes, respectively. The patients with PICB had significantly lower perioperative opioid consumption and trend towards lower pain scores.
Conclusions:
In this anatomical study, PICB at the 2nd and 4th ICS produced lateral spread along the corresponding intercostal space, medial spread to the adjacent paravertebral/epidural space and cranio-caudal spread along the endothoracic fascial plane. Clinically, combined PICBs at the same levels resulted in consistent segmental chest wall analgesia and reduction in perioperative opioid consumption after breast surgery. The incomplete overlap between paravertebral spread in the anatomical study and area of hypoesthesia in our clinical findings, suggests that additional non-paravertebral routes of injectate distribution, such as the endothoracic fascial plane, may play important clinical role in the multi-level coverage provided by this block technique.

Abstract
Background
Plasmodium falciparum is the number one cause of malaria morbidity and mortality. Several methods of intervention have been deployed in Cameroon with an attempt to reduce malaria transmission. But evaluation methods mostly based on microscopy and immunology have proven to be cumbersome and expensive. This study aimed at analyzing the genetic diversity of P.falciparum and the impact of ACTs deployment on MOI
Method
350 clinical isolates were collected between 2012 and 2013 and, three P. falciparum loci namely, msp-1(block2), msp-2 (block3), and glurp, (region II) characterized by nested PCR and DNA sequencing.
Results
From this study, a total of 16 different pfmsp1 were identified, including K1, MAD20 and RO33 allelic families. The K1 and MAD20 were the predominant polymorphic allelic types at the msp-1 gene, whereas alleles belonging to 3D7/IC were more frequent at the msp-2 gene. A peculiarity of this study is that RO33 revealed a monomorphic pattern among the msp-1 allelic type. Msp-1 and msp-2 revealed considerably greater parasite diversity than glurp. A total of 27 different msp-2 genotypes were recorded of which 15 belonged to the 3D7-type and 12 to the FC27 allelic families. Alignment of peptides encoded by pfmsp1 and Pfmsp2 reveals that K1 polymorphism had the highest similarity in the P.fmsp1 and Pfmsp2 clade followed by MAD20 with 93% to 100% homology. Indicating that P. falciparum isolates from Cameroon present high identity with allelic sequences from other areas in Africa, suggesting that vaccine developed with k1 and MAD20 of Pfmsp1 allelic variant could be protective for Africa children. The MOI ranged from 2.51 for msp1 to 3.82 for msp2. The overall heterozygosity ranged from 0.55 for msp-1 to 0.96 for msp-2 consistent with the genetic pattern observed in hyperendemic areas.
Conclusion
The present study reveals that isolates from South West Region of Cameroon are mainly polyclonal with high MOI and highly diverse in respect to both msp-1 and msp-2 despite ACTs deployment aiming at reducing malaria transmission. This study lays emphasis on the use of MOI and genotyping of both msp-1 and msp-2 in the evaluation of malaria control intervention in malaria endemics countries.

AbstractWith increased use of internet in daily lives, its negative effects are also being observed on physical, psychological and social health of individuals.Objective: To determine the effect of internet addiction (IA) on dietary behavior and lifestyle characteristics among university students.Methods: In this cross-sectional study, the subjects were students selected from four universities in Lahore, Pakistan through two-stage sampling (n = 322). Levels of Internet Addiction (IA) were assessed using Young Internet Addiction Test and demographics, dietary behavior and lifestyle factors using self-reportedquestionnaire.Results: Severe and moderate IA was present in 9.6% and 41.9% of population respectively. High prevalence was found among males, Private Sector University and engineering students. Frequent breakfast skipping, increased meal size and habit of snacking while using internet was found associated with IA. Internet Addicts were also used to eat less than recommended daily servings of dairy and fruit and more servings of meat group than their no internet addict counterparts (p < 0.05). Fast food and fried items were most consumed snacks, while carbonated beverages were most consumed beverages among internet addicts. IA was found associated with lesser physically activity, shorter duration of physical activity, disorganized sleep pattern and less duration of sleep (p < 0.05).Conclusion: Unhealthy dietary behavior and lifestyle habits were exhibited by internet addicts. University students should be educated regarding importance of balanced diet and healthy lifestyle for effectual primary prevention of numerous chronic diseases

The effects of power distance orientation difference between leaders and followers on attitudes and behaviors in military organizations
Authors: Choi YoungNam , Sohn YoungWoo , Kang EunKyoung 
Published: May 2019

The purpose of this study was to examine the effect of (in)congruence between leaders' and followers' power distance orientation(PDO) on organizational level variables and mediating effect of leader trust and cohesion in military organizations. A total of 288 ROK Army soldiers participated in this research and data were collected through survey. Inconsistent with previous research findings from person-supervisor fit studies, the results from polynomial regressions showed that congruence between leaders' and followers' PDO did not have a significant effect on organizational level variables in military organizations. Rather, when leaders' PDO was lower than followers', leader trust and cohesion decreased, and counterproductive work behavior(CWB) increased. Moreover, a double mediation estimate technique was conducted to investigate the impact of the PDO difference between leaders and followers on organizational level variables. We found that the relationship between the PDO difference and CWB was sequentially mediated by leader trust and cohesion. Based on the results, we discussed the implications and limitations of the study, and the directions for the future research.
