Transcriptome Analysis of Differentially Expressed Genes in Wild Jujube Seedlings under Salt Stress
Authors: Chang Xinyi , Sun Junli , Liu Lianling , He Wang , Zhao Baolong
Published: March 2020

Wild jujube (Ziziphus acidojujuba) and cultivated jujube (Ziziphus jujuba) belong to the family Rhamnaceae. Jujubes have marked drought- and salt-tolerant properties. After salt stress, wild jujube seedling growth was inhibited and photosynthetic efficiency was reduced. A bioinformatics approach was used to analyze the transcriptomics data from wild jujube seedlings grown under salt stress, and the genes differentially expressed under the salt stress were identified to provide a theoretical basis for the development and use of wild jujube plantations in salinized soil. The transcriptome sequencing from leaves of wild jujube seedlings was carried out using second-generation sequencing technology. The effects of salt stress on the differential expression of photosynthesis-related genes in wild jujube seedlings were analyzed. Transcriptome sequencing revealed a total of 5269 differentially expressed genes (DEGs), of which 2729 were up-regulated and 2540 were down-regulated. DEGs were mainly enriched with respect to photosynthesis, photosynthetic antenna proteins, glyoxylic acid and dicarboxylic acid metabolism, linolenic acid metabolism, cysteine and methionine metabolism, and porphyrin and chlorophyll metabolism. Among them, the photosynthesis pathway-related DEGs were most highly enriched. Further analysis of porphyrin and chlorophyll synthesis and photosynthesis-related pathways revealed that they were significantly enriched by 97 photosynthesis-related DEGs. The DEGs in the photosynthesis and photosynthetic antenna protein pathways were down-regulated, whereas the DEGs glutamyl-tRNA reductase (HEMA), ferrochelatase (HEMH), and pheophorbide a oxygenase (PAO) in the porphyrin and chlorophyll synthesis pathways were up-regulated, with the remainder being down-regulated. The nuclear gene encoding Rubisco, the key enzyme in the photosynthetic carbon fixation pathway, was also down-regulated. The results showed that the photosynthetic rate of wild jujube seedlings decreased following exposure to salinity stress, an effect that was related to the increased synthesis of 5-aminolevulinic acid and heme, and the up-regulation of expression of a gene encoding a chlorophyll-degrading enzyme, and was related to the down-regulation of gene expression in photosynthesis-related pathways such as light energy capture and carbon fixation. Selection of nine DEGs related to photosynthesis and chlorophyll biosynthesis by quantitative real-time-PCR confirmed that expression changes of these nine DEGs were consistent with the transcriptome sequencing results.
Assessment of brewery wastewater treatment by an attached growth bioreactor
Authors: Budgen Jack , Le-Clech Pierre
Published: March 2020

Craft beer is a rapidly growing market globally, placing an increased burden on wastewater treatment plants. To avoid discharge fees, new technology is required to make the on-site treatment of brewery wastewater affordable. This study assessed the application of a novel attached growth bioreactor (AGBR) to treat brewery wastewater to a discharge target (1,500 mg sCOD/L). Specifically, the impacts of the single-pass residence time (HRTsingle-pass), organic loading and media height were investigated. A HRTsingle-pass of 67 min demonstrated the shortest required time to meet the discharge target and the lowest final effluent concentration after 120 hr treatment time. Long HRTsingle-pass demonstrated slower biomass development, while smaller HRTsingle-pass caused an earlier rise in dissolved oxygen (DO) which hindered organic removal by heterotrophic bacteria. The sCOD removal rate increased with loading rates, however plateaued at 65 g sCOD/m2/day for loading rates above 300 g sCOD/m2/day. The media became flooded with biomass for feed strengths above 6.0 g sCOD/L. Greater media height provided additional surface area for biomass development, but marginally decreased the sCOD removal rate (g/m2/day) due to an earlier introduction of DO. Power consumption and footprint considerations found the greater media height to be the preferred choice for breweries.

Authors: Minakshi Prasad , Mohan Hari , Manjeet  , Ravina  , Brar Basanti , Shafiq Mohammad , Pundir C.S.
Published: March 2020

Metal nanoparticles (NPs) are described in the nanoscale and made from either pure metals or
their compounds such as oxides. Metallic NPs have certain indistinct functional groups due to which
these can bind with any type of ligand, antibody and drugs. Organic polymers, which conduct electricity,
are called conducting polymers (intrinsically conducting polymers). They behave like semiconductors by
exhibiting metallic conductivity. Process-ability is the major advantage of conducting polymers. Nanocomposite
is a novel material having nano-fillers scattered in a matrix with morphology and interfacial
characteristics of nano-composites including their individual property that influence their characteristics.
Conducting polymers and NP composites can enhance the rate of electron transport between the current
collector material (electrode) and the electrolyte; therefore they have been employed in the construction
of improved electrochemical sensors such as amperometric, catalytic and potentiodynamic affinity sensors.
The Upper and Lower Uterine Segment Thickness Ratio: A Simple Sonographic Tool to Triage for Preterm Delivery among Women with Threatened Preterm Labor
Authors: Anil Anapthi , Srinivas Sujatha Bagepalli , Hebbar Shripad , Pai Muralidhar Vaman
Published: March 2020

Background:

Preterm delivery is a predominant cause of neonatal morbidity and mortality.
Below 20% of women with threatened preterm labor, progress to active labor and delivery.
Identification of such women will help to improve neonatal outcome by an early intervention such
as administration of steroids and in utero transfer to the hospitals with better neonatal care.

Objective:

To evaluate the importance of ultrasonographic measurement of the upper and lower
uterine segments thickness ratio to distinguish between true and false labor in women with threatened
preterm.

Methods:

A prospective cohort study was carried out at a tertiary care hospital in Southern India
from June 2017 to July 2018 on 151 singleton pregnant women at 24-36 weeks of gestation with
regular or painful uterine contractions. Transabdominal ultrasound was performed to measure upper
and lower uterine segments wall thickness and then the thickness ratio was calculated. Delivery
within 7 days was the primary outcome of study.

Results:

Out of 151 patients, 32 (21.2%) delivered within 7 days of presentation and the rest
(78.8%) delivered after 7 days and had a significant difference in the ratio of upper/lower uterine
segments thickness (p<0.001). The ROC curve showed a sensitivity of 81.3% and specificity of
84.2% when the cut-off value of the thickness ratio was ≥1.61.

Conclusion:

The sonographic assessment of upper and lower uterine segment thickness ratio may
be helpful to differentiate true labor from false labor among women with threatened preterm labor.
Cancer Stemness as a Target for Immunotherapy is Shaped by Proinflammatory Stress
Authors: Unver Nese
Published: March 2020

Cancer stem cells represent a rare subpopulation of cancer cells carrying self-renewal and
differentiation features in multi-step tumorigenesis, tumor recurrence and metastasis. Proinflammatory
stress is highly associated with cancer stemness via induction of cytokines, tumorpromoting
immune cells and cancer stemness-related signaling pathways. This review summarizes the
major pro-inflammatory factors affecting cancer stem cell characteristics and the critical immunotherapeutic
strategies to eliminate cancer stem cells.

The Interactive Web-Based Program MSmonitor for Self-Management and Multidisciplinary Care in Persons With Multiple Sclerosis: Quasi-Experimental Study of Short-Term Effects on Patient Empowerment
Authors: Jongen Peter Joseph , ter Veen Gezien , Lemmens Wim , Donders Rogier , van Noort Esther , Zeinstra Esther
Published: March 2020

Background

Empowerment helps persons with a chronic disease to self-manage their condition and increase their autonomy and participation. MSmonitor (Curavista bv) is an interactive Web-based program for self-management and multidisciplinary care in multiple sclerosis (MS). It includes, among others, short questionnaires on fatigue (Modified Fatigue Impact Scale-5 [MFIS-5]) and health-related quality of life (HRQoL, Leeds Multiple Sclerosis Quality of Life [LMSQoL]); long questionnaires on disabilities, perception of disabilities (Multiple Sclerosis Impact Profile), and HRQoL (Multiple Sclerosis Quality of Life-54); a Medication and Adherence Inventory and an Activity Diary. The combination MFIS-5, LMSQoL, and Medication and Adherence Inventory constitutes the Quick Scan.

Objective

This study aimed to investigate the short-term effects of MSmonitor on empowerment in patients with MS.

Methods

We conducted a quasi-experimental study in a general hospital. Of the 180 patients with MS, 125 were eligible, 30 used MSmonitor, and 21 participated in the study (mean age 45.4 years, SD 10.2 years). A total of 24 eligible patients who did not use MSmonitor constituted the control group (mean age 49.3 years, SD 11.4 years). At baseline and at 4 months, we assessed self-efficacy (Multiple Sclerosis Self-Efficacy Scale [MSSES]), participation and autonomy (Impact on Participation and Autonomy [IPA] questionnaire), and self-management (Partners In Health [PIH] questionnaire). Differences between time points and groups were tested with paired t tests and χ² tests.

Results

In the MSmonitor group, follow-up values remained unchanged for MSSES control (P=.19), MSSES function (P=.62), IPA limitations (P=.26), IPA problems (P=.40), PIH recognition and management of symptoms (P=.52), PIH adherence to treatment (P=.80), and PIH coping (P=.73), whereas the PIH knowledge score had improved (mean 27.8, SD 1.7 vs mean 28.7, SD 2.0; P=.02). The overall utilization rate of the program components was 83% and that of the Quick Scan was 95%. In the control group, all outcomes had remained unchanged.

Conclusions

The results suggest that for first-time users of the MSmonitor program and their health care providers, it may not be justified to expect a short-term improvement in empowerment in terms of self-efficacy, self-management, autonomy, or participation. Furthermore, a lack of effect on empowerment is not because of nonusage of the program components.

Authors: Kalaitzoglou Evangelia , Majaliwa Edna , Zacharin Margaret , de Beaufort Carine , Chanoine Jean-Pierre , van Wijngaard-DeVugt Conny , Sperla Ervin , Boot Annemieke M , Drop Stenvert L S
Published: March 2020

BACKGROUND

Electronic learning (e-learning) is a widely accessible, low-cost option for learning remotely in various settings that allows interaction between an instructor and a learner.

OBJECTIVE

We describe the development of a free and globally accessible multilingual e-learning module that provides education material on topics in pediatric endocrinology and diabetes and that is intended for first-line physicians and health workers but also trainees or medical specialists in resource-limited countries.

METHODS

As complements to concise chapters, interactive vignettes were constructed, exemplifying clinical issues and pitfalls, with specific attention to the 3 levels of medical health care in resource-limited countries. The module is part of a large e-learning portal, ESPE e-learning, which is based on ILIAS (Integriertes Lern-, Informations- und Arbeitskooperations-System), an open-source web-based learning management system. Following a review by global experts, the content was translated by native French, Spanish, Swahili, and Chinese–speaking colleagues into their respective languages using a commercial web-based translation tool (SDL Trados Studio).

RESULTS

Preliminary data suggest that the module is well received, particularly in targeted parts of the world and that active promotion to inform target users is warranted.

CONCLUSIONS

The e-learning module is a free globally accessible multilingual up-to-date tool for use in resource-limited countries that has been utilized thus far with success. Widespread use will require dissemination of the tool on a global scale.
Automated Diagnosis of Various Gastrointestinal Lesions Using a Deep Learning–Based Classification and Retrieval Framework With a Large Endoscopic Database: Model Development and Validation (Preprint)
Authors: Owais Muhammad , Arsalan Muhammad , Mahmood Tahir , Kang Jin Kyu , Park Kang Ryoung
Published: March 2020

BACKGROUND

The early diagnosis of various gastrointestinal diseases can lead to effective treatment and reduce the risk of many life-threatening conditions. Unfortunately, various small gastrointestinal lesions are undetectable during early-stage examination by medical experts. In previous studies, various deep learning–based computer-aided diagnosis tools have been used to make a significant contribution to the effective diagnosis and treatment of gastrointestinal diseases. However, most of these methods were designed to detect a limited number of gastrointestinal diseases, such as polyps, tumors, or cancers, in a specific part of the human gastrointestinal tract.

OBJECTIVE

This study aimed to develop a comprehensive computer-aided diagnosis tool to assist medical experts in diagnosing various types of gastrointestinal diseases.

METHODS

Our proposed framework comprises a deep learning–based classification network followed by a retrieval method. In the first step, the classification network predicts the disease type for the current medical condition. Then, the retrieval part of the framework shows the relevant cases (endoscopic images) from the previous database. These past cases help the medical expert validate the current computer prediction subjectively, which ultimately results in better diagnosis and treatment.

RESULTS

All the experiments were performed using 2 endoscopic data sets with a total of 52,471 frames and 37 different classes. The optimal performances obtained by our proposed method in accuracy, F1 score, mean average precision, and mean average recall were 96.19%, 96.99%, 98.18%, and 95.86%, respectively. The overall performance of our proposed diagnostic framework substantially outperformed state-of-the-art methods.

CONCLUSIONS

This study provides a comprehensive computer-aided diagnosis framework for identifying various types of gastrointestinal diseases. The results show the superiority of our proposed method over various other recent methods and illustrate its potential for clinical diagnosis and treatment. Our proposed network can be applicable to other classification domains in medical imaging, such as computed tomography scans, magnetic resonance imaging, and ultrasound sequences.
Diabetes mellitus tipo 2: una problemática actual de salud en la población pediátrica
Authors: Carvajal Martínez Francisco , Bioti Torres Yadenys , Carvajal Aballe Mónica
Published: March 2020

La diabetes mellitus tipo 2 resulta de la combinación de resistencia a la insulina junto con inadecuada secreción de la misma. Su etiología es heterogénea, implicándose en los mismos, factores genéticos y ambientales. Su incremento ha sido significativo en las últimas décadas lo cual ha estado aparejado al incremento de la obesidad. Pudiendo existir tres formas de presentación: asintomática, sintomática y cetosis o cetoacidosis.

El desarrollo acelerado de las complicaciones está dado por una disminución más rápida y progresiva de la función de las células B que caracteriza esta enfermedad en la edad pediátrica.

El tratamiento incluye cambios del estilo de vida, el auto-control de la diabetes y el tratamiento farmacológico, siendo esencial involucrar a toda la familia en el manejo de este grupo de pacientes. Solo la metformina y la insulina han sido aprobadas para su utilización en este grupo de edad.

La prevención es la piedra angular para frenar la oleada de DM2 en niños y adolescentes a nivel internacional. Se basa en la identificación de los individuos en riesgo, diag-nóstico precoz de estados prediabéticos y la educación, dirigida a la familia y a la comunidad.

Entrevistas na pesquisa sócio-espacial
Authors: Kapp Silke
Published: March 2020

A coleta de dados por meio de entrevistas tem sido uma prática corrente nas pesquisas em arquitetura, urbanismo e planejamento, enquanto ainda são raras as discussões metodológicas sobre a pertinência, os objetivos, as formas de condução e as especificidades de entrevistas qualitativas nessas disciplinas. Este artigo visa a elucidar por que e como entrevistas qualitativas podem prover ou gerar dados sócio-espaciais cujas análise e interpretação, por sua vez, podem levar a conhecimento válido. Ele começa examinando as funções atribuídas a dados de entrevistas e seus limites. Em seguida, são evidenciadas diferentes ênfases de entrevistas partindo de cinco tipos consolidados em outras áreas (entrevista exploratória, etnográfica, narrativa, focada e especialista). A intenção não é propor escolhas entre eles nem criar mais um tipo, mas abrir um leque de variações a combinar, detalhar e expandir, de acordo com a situação específica de cada pesquisa.
Teacher Candidates’ Expectations: Equity Education, Critical Literacy, and Indigenous Students’ Epistemologies
Authors: Cherubini Lorenzo
Published: March 2020

Culturally responsive teachers respond positively to students’ cultural norms and traditions by creating inviting and meaningful learning opportunities that distinguish between Indigenous and western perspectives; however, in classrooms where teachers’ understanding of Indigenous epistemologies and worldviews are not necessarily sufficiently represented, Indigenous students not only often feel marginalized and isolated but disengaged from Eurocentric curriculum and texts that fail to incorporate their histories and traditions. This study focuses on the expectations and perceptions of teacher candidates (prior to their field practicum experiences in classrooms) related specifically to equity education, reflective practice, and critical literacy. The mixed-methods study examines prospective teachers’ perceptions of issues related to Indigenous students, and how public education policy and practice manifests in classrooms. The findings suggest that prospective teachers are doubtful of the fact that Indigenous voices are being presented competently to enhance student learning and foster Indigenous student identity. Moreover, prospective teachers anticipate a fundamental disconnect between the Ontario policy outcomes related to Indigenous education and the practice of teachers in school.

Paraovarian cyst as the cause of uterine prolapse
Authors: Cancar Vladimir , Ivanovic Radenko , Lalovic Nenad , Milinkovic Biljana , Sladoje Dragana
Published: March 2020

Paraovarian cysts originate from the mesothelium and are presumed to be remnants of M?llerian or Wolffian ducts. In majority of cases they are found to be 10-80 mm in diameter and do not cause any symptoms. Paraovarian cysts can be found unexpectedly during an operation or on ultrasound examination performed for other reasons. They are most freequently discovered on ultrasound examination. However, due to the proximity of the ovary for which cystic formations are not rare, the diagnosis of these lesions can be a challenge. They are mostly asymptomatic and only large lesions (?20 cm in diameter) become symptomatic. Although these are mostly benign tumors, in rare cases they can become borderline or true malignancies. Most paraovarian cysts are found in the third and fourth decade of life. Paraovarian cyst complications include: compression of the surrounding structures of the pelvis minor and abdomen, pelvic pain, cyst torsion and rupture. Except for the already mensioned complications available literature has so far failed to show cases of uterine prolapse caused by an increase of intra-abdominal pressure due to the expansive growth of giant paraovarian cystic formation.

Published: March 2020

Pheochromocytomas are rare tumors producing catecholamines that could be a cause of secondary hypertension. On that basis, pheochromocytoma can occur as an extremely rare cause of hypertension in pregnancy and if diagnosed late can lead to adverse maternal-fetal outcome. In this case report we describe a case of pheochromocytoma affected pregnancy with poor fetal outcome. A 27-year-old pregnant woman was admitted for severe pre-eclampsia due to pre-gestational hypertension that was diagnosed during the first trimester. Due to high and uncontrolled maternal blood pressure and the worsened maternal-fetal condition after the admission induction of fetal lung maturity and emergency cesarean section were performed, but with poor fetal outcome. Later, an adrenal gland mass was identified using abdominal ultrasound and confirmed by computed tomography. After surgical adrenalectomy blood pressure of the patient was normalized. Pheochromocytoma should be considered as a possible cause of hypertensive disorder during pregnancy, particularly in cases of severe and unresponsive hypertension in order to provide for timely and appropriate treatment.

Published: March 2020

Distributed generation is attracting much mindfulness as a viable option to giant centralized generation plants, driven by the fast evolving liberalization and deregulation environments. This interest is also motivated by the need for eliminating the needless transmission and distribution costs, drooping the greenhouse gas emissions, deferring capital costs and improving the availability and consistency of electrical network Therefore, disseminated generation is expected to play an escalating vital role in meeting future power generation supplies and to provide consumers with elastic and cost resistive solutions for many of their energy needs. However, the integration of these sources into the electrical network can cause some challenges regarding their expected impact on the safety and the active behavior of the full network. It is vital to study these issue and to analyze the permakeedance of the expected future systems to guarantee satisfactory operation and to maximize the benefits of utilizing the dis- tribute resources.

Avaliar os efeitos da corrente russa na região glútea como coadjuvante na atividade física com finalidade estética
Authors: Ribas Tailine Fernandes , Ritter Danila Soares , Horodeski Jaqueline Sueli
Published: March 2020

O cuidado com a aparência fisica, principalmente em mulheres, aumentou a procura por fisioterapeutas dermatofuncionais para tratamentos estéticos. Um glúteo firme, durinho e arredondado é o sonho de toda mulher. Com o passar dos anos, seja pela genética ou pelo sedentarismo, a região glútea tende a perder o tônus muscular. O tratamento denominado “corrente russa”, técnica de eletroestimulação neuromuscular desenvolvida no final dos anos 70 para prover ganho de força em atletas, também tem sido utilizado, nos dias atuais, para fins estéticos. Este trabalho consistiu em uma análise dos efeitos da corrente russa aplicada na musculatura da região glútea de mulheres praticantes de atividades físicas, como agente acelerador da hipertrofia muscular. Metodologia: foram selecionadas oito mulheres saudáveis, praticantes de atividades físicas, com grau 5 de força muscular em região glútea,  separadas em dois grupos iguais: Grupo A, formado por quatro mulheres submetidas a quinze sessões de corrente russa; Grupo B, ou grupo controle, composto de mulheres não submetidas à corrente russa. Ambos os grupos foram avaliados pré e pós período das sessões de corrente russa, em termos de perimetria da região glútea, peso corporal, percentual de gordura corporal, Escala de Opinião (Oenning, 2002), além da opinião pessoal das participantes sobre os efeitos da corrente russa. Objetivos: avaliar os efeitos da eletroestimulação neuromuscular do tipo “corrente russa” na musculatura da região glútea, como coadjuvante na atividade física, com finalidade estética; verificar se a corrente russa provoca hipertrofia muscular em região glútea; comparar os resultados obtidos do grupo submetido à corrente russa com o grupo controle. Resultados: a análise dos resultados numéricos obtidos, apesar de favorável em relação ao grupo controle e em relação à avaliação inicial, não revelou dados significativos, provavelmente, devido ao tamanho reduzido das amostras (p=0,61). Porém, na pesquisa de satisfação, a opinião pessoal das quatro componentes do grupo A foi unânime quanto à melhora da aparência da região gútea após o tratamento com corrente russa. Conclusão: foi possível concluir que houve melhora em termos de hipertrofia muscular em região glútea das participantes submetidas à corrente russa, assim como resultados positivos de satisfação pessoal das mesmas.

Trata-se de um estudo quantitativo que teve como objetivo conhecer os níveis de pressão arterial de adultos jovens (20 a 40 anos) moradores do município de Concórdia - SC. A pesquisa contou com 300 participantes, sendo 150 do sexo masculino e 150 do sexo feminino, para os quais foi aplicado um formulário de questões e verificado suas pressões arteriais. A coleta de dados foi feita no período de junho a agosto de 2010. Os dados coletados foram organizados num banco de dados, apresentados em tabelas e gráficos, analisados com estatística descritiva e discutidos com base na literatura estudada. Os resultados apresentaram uma prevalência de hipertensão arterial de 38,6% com predominância em sexo masculino, faixa etária de 20 a 30 anos, negros, moradores da zona urbana e naqueles que referiram história familiar da doença. A hipertensão auto-referida teve uma prevalência de 16,3% e destes, apenas 32,7% fazem uso de medicações anti-hipertensivas. Sobre a verificação periódica da pressão constatou-se que 76,6% não a fazem e, ao questionarem-se os motivos, 73,3% de todos os participantes não julgavam necessário verificar a pressão. Três participantes apresentaram níveis de pressão arterial sistólica ≥ 180 mmHg e/ou diastólica de ≥ 110 mmHg. Nesses casos, a pressão arterial foi novamente verificada depois de quinze dias. Todos eles se mantiveram hipertensos, porém somente um tinha diagnóstico prévio. Nenhum destes participantes apresentou manifestações clínicas no momento da verificação. Todos foram encaminhados para controle da PA nas unidades de saúde de referencia.

Published: March 2020

Este trabalho demonstra como um sistema de iluminação eficiente utilizando-se da tecnologia de diodos emissores (LEDs) pode ser economicamente viável a médio e longo prazo. Como o consumo de energia elétrica nas edificações tende a aumentar, relacionado à estabilidade da economia. O objetivo é demonstrar uma comparação financeira com parâmetros técnicos entre as diversas tecnologias empregadas em iluminação de ambiente residencial, podendo demonstrar o quanto podemos melhorar a eficiência energética através de uma elevada eficácia luminosa e longa vida útil na substituição dos sistemas de iluminação tradicionais, como lâmpadas incandescentes, fluorescentes tubulares ou fluorescentes compactas por LEDs sem qualquer alteração na instalação elétrica utilizando-se os conceitos da luminotécnica.

Relacionar Educação e Habilidades Sociais (HS) abre uma janela de possibilidades de estudo, pois na escola crianças e adolescentes desenvolvem estas habilidades (principalmente baseados na aprendizagem por modelação frente a comportamentos emitidos por colegas e professores). Um bom repertório comportamental é fator importante para o desenvolvimento de relações saudáveis, e investigar como esses conceitos vêm sendo utilizados no meio acadêmico e no trabalho de Formação Continuada de Professores torna-se importante para que ações sejam fomentadas pelo Psicopedagogo. Foram utilizadas três vertentes para a pesquisa: a pesquisa em sites de base de dados virtuais; nos Parâmetros Curriculares Nacionais; e nas Secretarias de Educação dos Municípios da Associação dos Municípios do Planalto Norte Catarinense (Ampla). A pesquisa dentro das bases de dados apontou muitos estudos sendo desenvolvidos, como o treinamento e desenvolvimento de HS dos professores, dificuldades de aprendizagem, inclusão de alunos com necessidades educativas especiais e prevenção da violência nas escolas. Nos Parâmetros Curriculares Nacionais constatou-se que o tema não é tratado com esse termo, mas é indiretamente contemplado em seu escopo. Finalmente, a pesquisa junto às Secretarias Municipais de Educação resultou numa pequena participação dos envolvidos, demonstrando pouco comprometimento com o trabalho de pesquisa. Nas Secretarias de Educação que responderam o questionário, a Formação Continuada é parte integrante da prática pedagógica, mas não há um trabalho específico utilizando as técnicas relacionadas ao tema. Os resultados apontam um ambiente propício ao trabalho do Psicopedagogo enquanto agente facilitador da Formação Continuada, principalmente quando utilizados os conceitos e técnicas relativas às Habilidades Sociais.
