As conclusões alcançadas evidenciam a importância do modelo KTMT incluir na sua conceção aspetos realçados pela investigação sobre integração da tecnologia, determinantes na caracterização do conhecimento da professora. Mostram ainda a relevância da prática para o desenvolvimento do conhecimento da professora e a perspectiva dinâmica sobre o conhecimento que este modelo pode proporcionar.
Our Experience with Inverted Papilloma: about 61 Patients
Authors: Philippe PrEloy , Valentine Leonard
Published: October 2021

Introduction: Inverted papilloma (IP) is the most common type of Schneiderian papilloma originating from the mucosal lining of the nose and paranasal cavities. It is a semi benign tumor with a high tendency for recurrences and malignant transformation. Management consists of a complete tumoral resection.

Objective: to analyze surgical results considering the techniques (open or endoscopic surgery), the rate and time of recurrence.

Method: We present herein a cohort of 61 patients treated in the CHU-UCL Godinne between 1998 and 2019. We analyzed the demographic data, the origin of the tumor, the staging, the surgical approach and the outcomes. The patients were classified into two groups: the first one includes 48 patients operated de novo in CHU-UCL Godinne and the second group 13 patients referred to us for revision surgery.

Results: We observed 8 recurrences, all groups confounded. The global success rate was 87%. The number of recurrences in the first group was 6 out of 48 and 2 out of 13 in the second group.

Following these results we propose an algorithm of treatment depending on the site of attachment of the IP.

Conclusion: We confirmed that more extended surgeries such as Caldwell Luc procedure, medial maxillectomy, Draf IIb/III frontal sinusotomy or type III sphenoidotomy give better outcomes than more “limited” and functional surgeries such as Draf I/IIa frontal sinusotomy or middle antrostomy. The latter should be done only for specific and limited extension of the IP in the maxillary sinus. A subperiosteal dissection is mandatory in all cases.

Keywords: inverted papilloma; retrospective study; surgery; recurrence
A Comparative Study of Difficulty Prediction Indices in Lower Third Molar Surgery
Authors: Carrillo Rivera Jorge Arnulfo , Bello Javier González
Published: October 2021

In third molar surgery, it is important to take into account multiple clinical and radiographic variables that, grouped into indices and classifications, allow estimating the degree of surgical difficulty. The present study proposes to evaluate the efficacy and congruence of these indices. Material and methods: a cross-sectional retrospective study in 77 patients. 123 lower third molar surgeries were performed using the Pederson, WHARFE and Parant prediction indices; to know the efficacy of the classifications, a statistical analysis with measures of central tendency, association through chi-square test and tables of frequency distribution were used, as well as non-parametric tests when determining an asymmetric distribution in the data through the Kolmogorov and Kruskall-Wallis test. Results: Analyzing the correlation between the Pederson and WHARFE indices, a strong association of P = .906 (Gamma), P = .761 (Kendall’s Tau “C”) and P = .834 (Somers “D”) was found, accepting frequency correlation through chi-square test. X2 test (P = 0.000) was performed accepting association between the Parant and Pederson scale, as well as for the WHARFE and Parant scales, resulting positive with a strong intensity and a direct association with a P = 0.796 (Gamma). Discussion: The difficulty prediction indices evaluated in the present study proved to be congruent with each other, their predictions regarding the type of surgery performed allow estimate degrees of complexity, type of surgical procedure, approximate time and possible complications, thus improving treatment planning. Keywords: Third molars; degree of difficulty; surgical tooth extraction; prediction

Utilização de recursos audiovisuais como estratégia de ensino de Microbiologia do Solo nos ensinos fundamental II e Médio
Authors: Vilas Bôas Rogério Custódio , Nascimento Junior Antonio Fernandes , Moreira Fatima Maria de Souza
Published: October 2021

O presente estudo buscou informações sobre uso de recursos audiovisuais (RA) pelos professores de Ciências e Biologia de uma escola pública no município de Lavras – MG, para subsidiar a produção de um vídeo. Este vídeo será usado como um organizador prévio para o ensino de Microbiologia do Solo no Ensino Fundamental e Médio. Este conteúdo é muito abstrato, fora do imaginário da maioria dos estudantes desses níveis de Ensino. Porém não pode ser negligenciado pelos professores e estudantes, para que percebam a importância dos micro-organismos do solo na sustentabilidade dos ecossistemas agrícolas e naturais. Os objetivos desse trabalho foram verificar com que frequência os professores e estudantes do 9º ano do Ensino Fundamental II e 3º ano Ensino Médio utilizam os RA como ferramenta na melhoria do aprendizado; identificar a preferencia dos estudantes entre os RA; verificar a frequência da utilização dos RA no Ensino de Ciências de Biologia e se professores e estudante concordam que o uso de vídeos/aulas poderia ajudar no ensino de Microbiologia do solo. A coleta de dados foi realizada através de questionários semiestruturados com perguntas objetivas e discursivas para os estudantes e professores. Após analise das respostas dos questionários, constatou-se que os professores não foram qualificados para utilizarem determinados recursos, e que os estudantes preferem aulas com uso de Datashow e acreditam que os R/A podem ajudar no ensino de Microbiologia do Solo. Os dados irão orientar a produção de uma vídeo/aula em Microbiologia do Solo para os estudantes.

Authors: França Elizabete França , Kataoka Adriana Massaê , Affonso Ana Lucia Suriani , Crisostimo Ana Lúcia
Published: October 2021

A educomunicação é um campo emergente que leva à apropriação democrática e autônoma de produtos de comunicação. A educomunicação socioambiental por sua vez tem como foco gerar saberes na interação social e com a natureza, enquanto que a Educação Ambiental crítica promove a emancipação dos diferentes grupos sociais. Portanto, essa pesquisa visou contribuir para o desenvolvimento de uma metodologia inovadora que visa a inserção dos princípios da Educomunicação e da EA crítica no cotidiano educacional, transpondo esses princípios teóricos em uma metodologia organizada em um material paradidático. A presente investigação adotou uma abordagem qualitativa do tipo pesquisa participante. Os resultados e discussão foram apresentados em três subitens: elaboração e descrição do material paradidático, intervenção pedagógica e avaliação do material pelos professores. Os sujeitos envolvidos no processo foram professores(as) de um colégio do campo da rede estadual do Paraná. As análises revelaram que na elaboração e descrição do material didático e na intervenção pedagógica, a transposição dos princípios teóricos dos dois campos do conhecimento esteve presente. A materialização dessa transposição se deu nas 3 peças educomunicativas elaboradas pelos professores. As entrevistas apontam para viabilidade da educomunicação socioambiental como uma metodologia de ensino para o aprofundamento da EA crítica dentro do espaço escolar, uma vez que não apresenta caráter pontual e não desvincula a teoria da prática. Assim, a educomunicação socioambiental dialoga com os princípios da EA crítica fomentando possíveis reflexões sobre os desafios contemporâneos socioambientais dentro das escolas, podendo ser acessíveis aso professores por meio do material paradidático analisado nessa pesquisa.

Authors: Pedroso Polyana Raquel , Gisi Maria Lourdes
Published: October 2021

A pandemia da Covid-19 é uma emergência de saúde pública e está afetando quase todo mundo no planeta, independentemente da idade, do nível de renda ou do país. No entanto, é provável que a crise econômica atinja especialmente as(os) jovens. As crises, em geral, atingem com mais intensidade as pessoas mais vulneráveis. Um desses grupos é o de jovens, que está particularmente exposto ao impacto socioeconômico da pandemia. O objetivo desse estudo foi analisar os impactos da pandemia da Covid-19 no que se refere à educação e ao trabalho para a juventude em âmbito nacional e internacional. Realizou-se uma análise documental qualitativa exploratória a partir dos sites oficiais da Organização Internacional do Trabalho (OIT), da Organização para a Cooperação e Desenvolvimento Econômico (OCDE) e da Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO). As fontes analisadas apresentaram grande preocupação com os impactos e com as consequências da pandemia para a juventude e em todas elas foram encontrados documentos significativos sobre a atual realidade juvenil. A crise da educação e do emprego juvenil impõe hoje aos governos em âmbito global muitos desafios, tanto para o acesso quanto para a permanência. Demonstrou-se que os impactos possuem diferentes dimensões e são relativos entre as particularidades dos países e regiões de cada um deles. A longo prazo, a combinada crise educacional e do mercado de trabalho ameaça não apenas prejudicar a qualidade e a quantidade de empregos, mas, também, exacerbar as desigualdades existentes entre países e dentro deles.

Music intervention pilot study
Authors: Rodakowski Juleen
Published: October 2021

Older adults facing cognitive challenges may face a decline in spatial skills and as a result may become less confident in navigating their environment. Spatial training has been shown to help ease this decline, and engaging in music has been shown to benefit the spatial skills of musicians. There is a paucity of research investigating ways that music might serve as spatial training for older adults. This study explored music classes as a means of spatial training for older adults across three domains; 1. improving their success rates in staying spatially oriented on the instrument; 2. enhancing their ability to read written music and 3. in reaching better outcomes on a spatial orientation test taken at pre- and post-intervention. Our team developed and tested a 6-week marimba class that targeted spatial training principles for older adults with predementia or early dementia. We assessed the spatial skills with the Orientation Test from the Test of Visual Perceptual Skills pre- and post-intervention. Scores increased an average of 0.71, a clinically meaningful change (d = 0.3). Participants also demonstrated high frequencies of remaining oriented on the instrument. There was also higher incidence of participants’ self-selecting to read music without notes (p < 0.01) over the course of the intervention.
Future research might benefit from music-based training as a means to support spatial skills during cognitive decline.
Development of the Caregiver Confidence using Music Scale
Authors: Kim David , Ruan Brandon , Bartel Lee , Foster Bev , Mackinnon Chelsea
Published: October 2021

Music serves as an important tool to improve the health and wellness of individuals in healthcare settings. In times of high caregiver burnout, therapeutic outlets such as music for care receivers and providers are becoming increasingly important. This paper presents the first iteration of the Caregiver Confidence using Music Scale (CCuMS), an assessment tool designed to evaluate caregivers’ readiness to adopt music care. Music care is defined as the informed and intentional use of music by anyone to improve the quality of care. The CCuMS was derived from a hierarchical cluster analysis of the Music Care Training program’s Level 1 post-evaluation survey (Post-MCTL1). Thematic interpretation of the statistical outputs from the cluster analysis was completed, resulting in the first iteration of the CCuMS. Initial validation methods that were feasible with current data were conducted. Specifically, face validity, content validity and convergent validity were calculated using Pearson correlations. The CCuMS shows promise as a measurement tool for use in healthcare settings due to the moderate correlation between the Post-MCTL1 and the CCuMS scale (r=0.524), and the strong correlation between the music care training thematic questionnaire and the CCuMS (r=0.970).

Published: October 2021

Coronary angiography is a procedure in which patients tend to present with a moderately high level of stress and anxiety. The present investigation sought to examine the impact of a patient controlled music listening intervention by mobile application (Music-Care) on sedative consumption as primary endpoint, and on pain, anxiety and satisfaction levels. This is a prospective non-randomized controlled clinical study. Patients scheduled to undergo coronary angioplasty under local anesthesia and sedation were recruited. A 76 patients were included, 54 were assigned under the music arm and 22 under the control arm. Medication intake during the procedure has been reported as well as anxiety as measured by numeric rating score and APAIS, pain and satisfaction scores. Music group was administered "U" sequence during the procedure. Patients under music took significantly less midazolam medication (median 1 vs 3 mg in control, p<0.01). Additionally, there was a significant difference (p<0.01) on anxiety (Mmusic = 2.9, Mcontrol = 4.2, p <0.01) but not in pain score. Almost all of the patients from the music group (98%) were satisfied (score ≥ 4) vs 91% in control group. Music-Care program application provides a 2/3 reduction in midazolam sedation during coronary angiography under local anesthesia and sedation. Furthermore, cardiologists appreciated this technique and suggested it to assist with their procedure in ambulatory practice.

A Review on Policy Gaps of Agriculture Research and Development (R&D) in India and Their Effect on Agriculture Stakeholders
Authors: Ridhi R. , Nirmala C.
Published: October 2021

Purpose: An impressive stride in the agriculture sector in India after green revolution from a food deficient to food surplus country is attributed to the well-established infrastructure and contribution of various farm families in this sector. In the current scenario, various cons of food surplus and other stagnation issues of the policies need to be contemplated. The various policy reforms should inculcate well utilization of agriculture investment funds, methodologies to allow increments in farmer’s income to prevent their suicidal rates, incentives and requirements for private R&D investment in agriculture while maintaining the sustainable development goal of India. A complete transparent paradigm approach to be followed by the central, state governments and private sectors for fostering agriculture growth is analyzed in this review. The impetus behind the lack of agriculture growth in spite of tremendous productivity measures adopted by farmers, policy makers; public and private investment lies in lacking of an appropriate infrastructure as per current need and demand. It is imperative to foster paradigm protocol in agriculture with articulate government intermediaries to prevent monopoly of a particular authority in due course of time. It develops spurring behavior among stakeholders to form a consortium to revitalize the complete agriculture R&D to obviate the bottle necks hampering agriculture proliferation.
Design: The present review highlights the mandatory need in the current scenario to review the agriculture research and development policies and desired amendments as per the needs of the associated stake holders.

Authors: Larrea Witor Hugo Guedes , VIANA FRANCISCA DIANA FERREIRA , Braga Francisco Laércio Pereira
Published: October 2021

Este artigo tem por objetivo principal verificar os efeitos das políticas públicas nacionais no processo de construção e afirmação social das comunidades Quilombolas remanescentes no Brasil por meio de trabalhos científicos nacionais a partir dos anos 2000. A pesquisa foi realizada fazendo-se uso de uma análise bibliográfica de estudos publicados a partir dos anos 2000 em plataformas digitais e analisados pelo software IRAMUTEQ. Através dessa análise verificou-se que a maior parte dos trabalhos publicados continha um ou mais tema que os aproximavam e, em sua maioria, foram publicados em revistas especializadas em Políticas Públicas. Ao final da análise, os resultados mostraram que apesar do grande número de políticas públicas desenvolvidas, nem todas são implementadas ou chegam às comunidades remanescentes de quilombos. Dessa maneira, as comunidades ficam dependentes dos interesses dos governos (Federal, Estadual ou Municipal). Além disso, os trabalhos analisados, apesar de proximidade com a temática, pouco se conectam, o que os tornam distantes em suas abordagens.

Entre o dilaceramento e a alegria: considerações sobre a velhice na literatura brasileira de autoria feminina
Authors: Pereira Maria do Rosário Alves , Maia Claudia Cristina
Published: October 2021

Este artigo apresenta um breve estudo sobre a velhice feminina representada na literatura brasileira escrita por mulheres. Parte de um preâmbulo que procura informar sobre a ausência do tratamento dessas personagens em nossa literatura para depois analisar narrativas curtas (contos e minicontos) das seguintes escritoras: Clarice Lispector, Lygia Fagundes Telles, Cíntia Moscovich e Alê Motta. A análise é ancorada no pensamento de Simone de Beauvoir, Natalia Ginzburg, Eurídice Figueiredo, Carmen Lucia Tindó Secco e outras pesquisadoras, que apresentam importantes reflexões sobre a velhice, com destaque para a questão da solidão, que se mostrou recorrente nas narrativas selecionadas para o corpus, mas tratada de forma distinta em cada uma delas. A intenção não é traçar um panorama de tais representações, o que demandaria um estudo de mais fôlego, mas apontar algumas recorrências e particularidades quanto à temática, sobretudo no que toca à autoria feminina. Saliente-se que o tema da velhice faz-se pertinente para a análise pois é pouco estudado na literatura brasileira em geral, o que aponta para a relevância desta investigação.
Imposing demands on precision influences the hands differently during alternated discrete touching
Authors: Marcori Alexandre Jehan , Monteiro Pedro Henrique Martins , Okazaki Victor Hugo Alves
Published: October 2021

Purpose

How demands of precision influence the performance during alternated discrete touching is not well established in the literature. Hence, we compared both hands performance during alternated touching, manipulating the precision demand.

Methods

Overall, 23 right-handed adults participated in this study. The first task consisted of alternated touching with a pencil on both sides of a blank paper, performing as fast as possible, considering the first touch as reference for the next ones. Subsequently, touch dispersion and width were measured, and circular targets were drawn with those proportions. The second task consisted of performing as many hits as possible inside those targets. Apart from the delimitated target, increasing precision demand, the task parameters were equal.

Results

Movement time increased and the number of touches decreased from the first to the second task. However, the preferred hand displayed greater reductions in performance.

Conclusions

The perceptual constraint of adding a visual target affects motor control parameters in alternated touching, causing decrements in performance in both hands, but more evidently in the preferred right hand.

Published: October 2021

Purpose

The purpose of this study was to analyse the goals in soccer Italian League Serie A (2018–2019) in relation to (a) the number of total attempts; (b) the time reached; (c) the area from which the final action occurred. Also, the effect of achieving the first goal in the match outcome was studied.

Methods

A total of 380 matches were studied, with 1019 goals scored. All matches were analysed with the SportScout software. Chi-square test was used to find differences between the display frequencies of each variable.

Results

More goals were scored in the second half of the match (χ2 = 25.438, p < 0.05) and in the last 15 minutes. Most goal attempts were made through the penalty box and outside of it (χ2 = 2365.002, p < 0.05), though the highest success rates were shown in the attempts from the goal box. Overall, 30% of the total number of goals were scored from set plays (χ2 = 171.493, p < 0.05), most of them after a corner shot (χ2 = 18.488, p < 0.05). Furthermore, it appeared that the first goal had a strong impact on the final outcome since in 67.34% of the cases, the team that scored first won the match.

Conclusions

More goals were scored in the second half, especially in the last 15 minutes. Coaches should prepare their players to be fit to cope with the whole match. They will also need to improve their defensive and offensive tactics in set plays.

Published: October 2021

The issue of cell-to-cell interferences is a serious problem that has always been raised in digital communication system such as NR. The communication method of NR and LTE is OFDM. OFDM has many advantages, but has fatal disadvantage called ICI (Inter-Cell Interference) because resources among cells are always overlapped. For example, NR’s typical interferences are ICIs among PDSCH (Physical Downlink Shared Channel), PDCCH (Physical Downlink Control Channel), PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel), CSI-RS (Channel State Information-Reference Signal) and SRS (Sounding Reference Signal). Among them, it is important to determine the correct beamforming weight factor value by estimating the channel with SRS. Therefore, the ICI of SRS degrades the performance of downlink throughput. This paper analyses the impact of SRS’s ICI in conventional scheme, introduces the proposed AC-CS (Auto-Correlation Cyclic Shift) schemes by the Zadoff-Chu sequence to overcome the ICI of SRS and analyses theirs performance. The method used for performance analysis is determined by the detection abilities, which are missing probability and false alarm probability.

Published: October 2021

As a musician and producer, I’ve always struggled with finding chords when I first started writing music [5]. It sometimes goes to the extent of me forgetting my melody because I take so long trying to figure out the chords. So I came up with an idea for this app, that will help amateur and beginner musicians save time and provide chord suggestions to them as a booster to start writing songs [6]. It features a recording or a midi input feature, then the app will carefully analyze the given melody and give a selection of the best chord progressions using intelligent AI. As an output, it is able to present it as guitar chords, piano chords, and ukulele chords, enabling more different musicians to use this app.

Introduction and Aim:Emergence of different applications of metallic nanoparticles in various field leads to innovation of new synthetic strategies. Besides being non-toxic to mammalian cells, zinc oxide nanoparticles (ZnONPs) has gained paramount attention due to its excellent antibacterial potential. This study illustrates a comparative analysis of antibacterial and cytotoxic activity of both phytochemically synthesized and chemically synthesized commercially available ZnONPs.

 

Materials and Methods:As a source of reducing agent, leaf extract of Coriander sativum was employed in case of green synthesis of ZnONPs. Several techniques, such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Dynamic light Scattering (DLS) and Field emission Scanning Electron Microscopy (FESEM) were performed to characterize both green synthesized and commercial ZnONPs.Antibacterial potential of both theZnONPs were investigated on Gram-positive and Gram-negative bacterial strains to draw a correlative outcome. Hepatocellular cell line was used to determine the cytotoxic activity of both ZnONPs.

 

Results:Both the nanoparticles showed antibacterial and cytotoxic activity with measurable degree of difference.

 

Conclusion: From these studies it can be concluded, the green synthesized nanoparticles showed greater antibacterial as well as cytotoxic activity in comparison to the commercial ZnONPs.

Published: October 2021

Introduction and Aim:HaemophagocyticLymphohistiocytic Syndrome (HLH) is a fatal disease with characteristic proliferation of histiocytes in the organs including bone marrow, liver, spleen, kidney, csf, meninges, lymph nodes and subcutaneous tissue which phagocytes the blood cells. In all unexplained cases of cytopenias, organomegaly and pyrexia of unknown origin the HLH should be thought off. Though there are established criteria to diagnose, early diagnosis can reduce the mortality rate due to HLH. Documenting the haemophagocytes in the biopsy can sometimes be very helpful in arriving at the diagnosis.

 

Materials and Methods:We identified patients who were diagnosed with or suspected to have HLH by bone marrow aspiration or biopsy admitted to Sri Ramachandra Medical College Hospital and Research Institution from January 2010 to June 2017.We retrospectively reviewed patients’ medical records that have haemophagocytes in bone marrow aspirations and collected complete clinical history and laboratory findings. Those history included fever, cytopenias, and organomegaly. Their triglyceride levels, ferritin, ESR or any other abnormal elevated lab values were also noted down. If they had any established diagnosis then that was also noted.

 

Results:This is a descriptive study and the details of the data like clinical history, clinical features, laboratory investigations and abnormal values are represented using tabular column, Pie chart and bar diagrams.

 

Conclusion:From pathological point of view, documenting each case presenting with Haemophagocytes and looking into the factors like age, significant laboratory values along with clinical features can be a valuable tool to come to a provisional diagnosis and might help the clinician to proceed with the treatment for alife-threatening disease without much delay.

Published: October 2021

Introduction and Aim:To find the effectiveness of task-based mirror therapy when compared with constraint-induced movement therapy for hand function in hemiplegic subjects. Stroke is a major health problem in the world. According to various researches, 70%-80% of the patients have the upper extremity impairment then lower extremity. Task-based mirror therapy can be an effective management for premotor cortex impairment. Constraint-induced movement therapy forms the new neural pathway when used properly.

 

Materials and Methods:30 patients with subacute CVA (cerebrovascular attack) were enrolled and randomly divided into two groups: constraint-induced movement therapy (CIMT) and task-based mirror therapy (TMBT). The full-Meyer motor function assessment was evaluated 4 weeks after treatment.

 

Results: The results showed that mean value of TMBT (pre-test – 5.733, post-test- 9.86) and SD of (pre-test- 1.67, post-test- 1.92) and in CIMT(pre-test-6.3, post-test-11.13) and SD (Pre-test-1.45,Post-test -1.36).

 

Conclusion:This study shows that CIMT group showed more improvement than TMBT group.

Authors: Karim Dhuha
Published: October 2021

The mean age of AS patients was (35.0 ± 9.8) years.When the patients and control subjects were divided into different age groups (>40, 30-40, <30 years), the differences were not significantin terms of disease prevalence. The results also showed that the percentage of male patients is higher than that of females. There was no significant difference (P?0.05) between patients and controls in the distribution of males and females.Most of the patients had the disease for a period of 5 years or higher, with a disease severity of ? 2.1 and functional disability degree of I, II. The resultsshoweddifferent patterns of distribution for the three tested cytokines. A significant increase in the level of TNF-?, anon-significantincrease in the level of CXCL-8, and a significant decrease in the level of IL-10 were observed in the sera of patients with AS compared with the control.The patients also demonstrated significant decreases in the serum ALT and AST enzyme levels, hemoglobin (Hb) level, white blood cells (WBC) count, and erythrocyte sedimentation rate (ESR) (P?0.05).The percentage of HLA-B27-positive Iraqi patients was lower than that of the HLA-B27-negative patients. Some of these patterns were also exposed to changes related to some determinants in patients, which included age, sex, disease duration, disease severity, functional disability, and HLA-B27 positivity,along with association with clinical subtypes of AS.The area under the curve was determined for the parameters of ESR, IL-10, TNF-? and CXCL-8.The most significant factor was found to beESR, followed by IL-10, and then TNF-?, with the presence of significant differences, while there was no diagnostic significance for CXCL-8 ,which showed no significant difference (p?0.05).

En este artículo se hace un examen del proceso electoral de marzo del 2000. Su tesis fundamental es que los resultados de las recientes elecciones consolidaron, en el plano legislativo, el equilibrio de poder existente entre el FMLN y ARENA. Para los autores, el principal desafío del FMLN consiste en aprovechar esas tendencias favorables para asegurar su predominancia legislativa y municipal en el futuro inmediato. Mientras que el desafio de ARENA es hacer lo que esté a su alcance para contener ese ascenso político del FMLN, cuya inminencia se hace patente a la luz de los resultados electorales obtenidos principalmente a nivel municipal.
