Les ruses de la transgression juvénile. Défier les adultes : style de déviance et engagement existentiel
Authors: Boukir Kamel
Published: August 2020

À hauteur d’adolescents, la transgression peut être un moment d’exaltation. En se socialisant au pluralisme normatif qui fait la ville, passant d’une institution de délégation éducative à l’autre (famille, école, maison de la jeunesse et de la culture, centres de loisirs, clubs de sport, etc.), les jeunes font l’épreuve de la continuité écologique du régime asymétrique de déférence vis-à-vis de l’autorité des adultes. Au miroir de ce devoir d’obéissance, la transgression juvénile acquiert un pouvoir interactionnel de redéfinition du sens et de la vocation de la salle de classe : non le travail mais l’amusement. Défier les adultes se comprend alors comme un style de déviance d’une part, exaltant la volte-face, l’aventure et l’audace, et comme un engagement existentiel, l’école devenant l’espace moral d’une dramaturgie de soi où consacrer son rang dans la hiérarchie juvénile.

Published: August 2020

In this article, we deal with the existence of S-asymptotically \begin{document}$ \omega $\end{document}-periodic mild solutions of Hilfer fractional evolution equations. We also investigate the Ulam-Hyers and Ulam-Hyers-Rassias stability of similar solutions. These results are established in Banach space with the help of resolvent operator functions and fixed point technique on an unbounded interval. An example is also presented for the illustration of obtained results.
A polyhedral conic functions based classification method for noisy data
Authors: Acar Müge , Kasimbeyli Refail
Published: August 2020

This paper presents a robust binary classification method, which is an extended version of the Modified Polyhedral Conic Functions (M-PCF) algorithm, earlier developed by Gasimov and Ozturk. The new version presented in this paper, has new features in comparison to the original algorithm. The mathematical model used in the new version, is relaxed by allowing some inaccuracies in an optimal way. By this way, it is aimed to reduce the overfitting and improve the generalization property. In the original version, the sublevel set of a separating function generated at every iteration, does not contain any element of the other set. This is changed in the new version, where the sublevel sets of separating functions generated by the new algorithm, are allowed to contain some elements from other set. On the other hand, the new algorithm uses a tolerance parameter which prevents generating "less productive separating functions". In the original version, the algorithm continues till all points of the "first" set are separated from the second one, where a separating function is generated if there still exist unseparated elements regardless the number of such elements. In the new version, the tolerance parameter is used to terminate iterations if there are only a few unseparated elements. By this way, it is aimed to improve the generalization property of the algorithm, and therefore the new version is called Parameterized Polyhedral Conic Functions (P-PCF) method. The performance and efficiency of the proposed algorithm is demonstrated on well-known datasets from the literature and on noisy data.
Protection of Low Carbon Steel in Industrial Cooling Water System by New Formulation
Authors: Rochdi Abdelhadi , Touir Rachid , Ebn Touhami Mohamed
Published: August 2020

This chapter studies the operational parameters effects, such as immersion time, corrosion products, and pH, on the inhibition efficiency against corrosion for low carbon steel in simulated cooling water system of the mixture 1 (10-3 M 3-MPOX + 20 ppm CTAB), which corresponds to the best inhibition efficiency. The results show that the corrosion inhibition performance of the studied mixture reinforces with immersion time and has a maximum in the pH range 6.5–7.5. In addition, the analysis of the results shows that there is a dependence of the pH value of the solution and the corrosion current density (icorr). Indeed, a correlation can be established between log (icorr) and the pH using the polynomial equation. Finally, the mixture 1 provides good protection for the attack materials. These studies were evaluated from the polarization curves (PP), electrochemical impedance spectroscopy (EIS).

Authors: Touir Rachid , Larhzil Hayat
Published: August 2020

In this study, scale inhibition performance Trisodium citrate (TSC) was studied using static scale inhibition method, and its corrosion inhibition performance was also investigated by weight loss method and electrochemical measurement. Result showed that TSC could form a layer of corrosion and scale produTSC on mild steel surface in synthetic cooling water. Its inhibition increases with concentration and reaches a maximum of 89% and 95% at 10-3 M for corrosion and scale, respectively. It is noted that TSC takes its inhibition at high temperature and act by physic-sorption process. It is found that the TSC obey to the Langmuir isotherm. Scanning electron microscopy (SEM) showed that TSC inhibits the scale and corrosion by the formation of a protective layer on the mild steel surface.
Corrosion Assessment and Control Techniques for Reinforced Concrete Structures
Authors: Daniyal Md , Akhtar Sabih
Published: August 2020

The steel reinforced concrete structures perform well in various environmental conditions, but structures may undergo premature damage in aggressive environments such as marine or acidic, primarily due to steel corrosion, and substantial reduction in service life occurs. This also causes huge economical loss and create safety and environmental problems. The repair and maintenance of steel reinforced concrete structures for their safety needs effective monitoring and inspection systems for evaluating the corrosion condition of steel. Since the corrosion of steel reinforcement occurs through electrochemical reactions, electrochemical methods are suitable to study the corrosion processes. In this chapter, some commonly used electrochemical techniques have been comprehensively explained. In addition, there is a critical requirement to develop effective and long-lasting techniques to control the corrosion of steel. Hence, some of the commonly used corrosion control methods have been comprehensively described in this chapter.

Authors: Lampprecht Tobias , Salb David , Mauser Marek , van de Wetering Huub , Burch Michael , Kloos Uwe
Published: August 2020

Formula One races provide a wealth of data worth investigating. Although the time-varying data has a clear structure, it is pretty challenging to analyze it for further properties. Here the focus is on a visual classification for events, drivers, as well as time periods. As a first step, the Formula One data is visually encoded based on a line plot visual metaphor reflecting the dynamic lap times, and finally, a classification of the races based on the visual outcomes gained from these line plots is presented. The visualization tool is web-based and provides several interactively linked views on the data; however, it starts with a calendar-based overview representation. To illustrate the usefulness of the approach, the provided Formula One data from several years is visually explored while the races took place in different locations. The chapter discusses algorithmic, visual, and perceptual limitations that might occur during the visual classification of time-series data such as Formula One races.

This chapter details an estimation method using the principal component analysis (PCA) solution based on the connection between PCA solution and membership of clusters from K-means from research. All the mathematical justification is provided. The evaluation has been done empirically with a comparative study. The validation results show the significant feasibility of the proposed method to initialize parameters.
Search-Based Classification for Offline Tifinagh Alphabets Recognition
Authors: Erritali Mohammed , Chouni Youssef , Ouadid Youssef
Published: August 2020

The main difficulty in developing a successful optical character recognition (OCR) system lies in the confusion between the characters. In the case of Amazigh writing (Tifinagh alphabets), some characters have similarities based on rotation or scale. Most of the researchers attempted to solve this problem by combining multiple descriptors and / or classifiers which increased the recognition rate, but at the expense of processing time that becomes more prohibitive. Thus, reducing the confusion of characters and their recognition times is the major challenge of OCR systems. In this chapter, the authors present an off-line OCR system for Tifinagh characters.

Updating the dictionary: Semantic change identification based on change in bigrams over time
Authors: Nimb Sanni , Sørensen Nicolai Hartvig , Lorentzen Henrik
Published: August 2020

We investigate a method of updating a Danish monolingual dictionary with new semantic information on already included lemmas in a systematic way, based on the hypothesis that the variation in bigrams over time in a corpus might indicate changes in the meaning of one of the words. The method combines corpus statistics with manual annotations. The first step consists in measuring the collocational change in a homogeneous newswire corpus with texts from a 14 year time span, 2005 through 2018, by calculating all the statistically significant bigrams. These are then applied to a new version of the corpus that is split into one sub-corpus per year. We then collect all the bigrams that do not appear at all in the first three years, but appear at least 20 times in the following 11 years. The output, a dataset of 745 bigrams considered to be potentially new in Danish, are double annotated, and depending on the annotations and the inter-annotator agreement, either discarded or divided into groups of relevant data for further investigation. We then carry out a more thorough lexicographical study of the bigrams in order to determine the degree to which they support the identification of new senses and lead to revised sense inventories for at least one of the words Furthermore we study the relation between the revisions carried out, the annotation values and the degree of inter-annotator agreement. Finally, we compare the resulting updates of the dictionary with Cook et al. (2013), and discuss whether the method might lead to a more consistent way of revising and updating the dictionary in the future.
A comparison of collocations and word associations in Estonian from the perspective of parts of speech
Authors: Vainik Ene , Tuulik Maria , Koppel Kristina
Published: August 2020

The paper provides a comparative study of the collocational and associative structures in Estonian with respect to the role of parts of speech. The lists of collocations and associations of an equal set of nouns, verbs and adjectives, originating from the respective dictionaries, is analysed to find both the range of coincidences and differences. The results show a moderate overlap, among which the biggest overlap occurs in the range of the adjectival associates and collocates. There is an overall prevalence for nouns appearing among the associated and collocated items. The coincidental sets of relations are tentatively explained by the influence of grammatical relations i.e. the patterns of local grammar binding together the collocations and motivating the associations. The results are discussed with respect to the possible reasons causing the associations-collocations mismatch and in relation to the application of these findings in the fields of lexicography and second language acquisition.

Authors: Nwafor Christopher Ugochukwu , Ogundeji Abiodun A. , Van der Westhuizen Carlu
Published: August 2020

This study examined marketing information needs and seeking behaviour among smallholder livestock farmers from the Eastern Cape province in South Africa. Structured questionnaires were used to collect data from 150 livestock farmers and analysed using percentages, weighted means for ranking and correlation. The results show a dominance of market price information requirement among farmers (65%), immediate market price information need (38%), high level of need (48%), and a strong reliance on sources such as other farmers (36%), phone calls (24%) and auctions (23%) for market information. In addition to this, the listed demographic characteristics of farmers namely age, sex, education, marital status, household size, income and herd size strongly influenced their information seeking behaviour (p<0.05). Provision of additional sources of market price information, and ensuring that the personal features of farmers are taken into consideration when designing information service  interventions is crucial.

Evaluation of Extracts of Leaves of Crinum jagus for Antimicrobial Properties
Authors: Alawode T.T. , Lajide L. , Owolabi B.J. , Olaleye M.T.
Published: August 2020

Plants have been used in ethno-medicine for ages in the treatment of various diseases. In the current study, the leaves of C. jagus are investigated  for antimicrobial activities. The leaves were dried and extracted successively with hexane, ethylacetate and methanol. The concentrated extracts  were screened for activity against Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella typhi, Klebisidlae pneumonae, Candida albicans, Aspergillus niger, Penicillium notatum and Rhizopus stolonifer at concentrations between 6.25 and 200 mg/ml using the agar diffusion method. The Minimum Inhibitory Concentration (MIC) was also determined. The percentage yields obtained were 0.92 %, 1.20 %  and 25.2 % for the hexane, ethylacetate and methanol extracts respectively. The zones of inhibition of the organisms by the extracts generally increased with the concentrations. The methanol extract showed the best activity of the three extracts tested. The methanol extract had values ranging between 20 mm and 26 mm against the bacteria at 200 mg/ml. This extract also showed values between 18 mm and 20 mm against the  fungi at 200 mg/ml. The lowest MICs values (of 2.5 mg/ml) were obtained against S. aureus, E. coli, B. subtilis and S. typhi. The polar constituents in  the leaves of the plant are likely responsible for the antimicrobial properties observed. None of the extracts showed activity comparable to those of the standard drugs, however the methanol extract showed some potential as a source of antimicrobial compounds.

Bed Sediment samples were collected in the Dry Season from Orashi River at three sampling sites each located in Mmahu, Opuoma, Abacheke and Ogwu Aniocha communities. Physicochemical parameters, hydrocarbon and heavy metal (As, Cd, Fe and Pb) concentrations were determined with standard methods. Results showed that total petroleum hydrocarbon (TPH) ranged from 0.11 ±0.03 to 1.91 ±0.25 mg/kg while total hydrocarbon content (THC) and oil and grease had ranges of 0.28 ±0.06-2.98 ±0.19 and 0.69 ±0.09-3.60 ±0.57 mg/kg respectively. The sediment samples were classified as unpolluted in terms of TPH. Mean values for pH had a range of 4.33 ±0.22 - 6.60 ±0.52 while the texture of most samples was sandy. Mean organic carbon contents ranged from 0.58±0.07 to 3.15±0.66 % and mean total nitrogen and total phosphorus had ranges of 0.30±0.00 -2.77±0.46 and 17.34±1.65 - 29.48±1.63 mg/kg respectively. Mean Mg concentrations were significantly higher (P<0.05) than the concentrations of other exchangeable bases and mean As concentration had a range of 1.175±0.086-1.291±0.335 mg/kg. Mean Cd concentrations ranged from 0.948±0.072 to 3.120±0.131 mg/kg while mean Fe and Pb concentrations had ranges of 57.324±10.530-159.707±41.192 and 1.300±0.295-7.462±0.861 mg/kg respectively. As and Pb values were lower than the sediment quality guidelines (SQG) but Cd values were higher than the guidelines in all sites. Contamination factors (CFs) for As and Pb indicated low contamination while CFs for Cd indicated moderate to considerable contamination. Geo-accumulation index (Igeo) values for As and Pb at all sites and that of Cd at one site indicated unpolluted, Igeo values for Cd at all other sites ranged between 0.210 and 1.571 indicating unpolluted to moderately polluted status.

The demand and utilization of petroleum products have re-energized its exploration and exploitation globally and this upsurge in world production, refining and distribution of petroleum products have brought with it various problems of environmental pollution, which have effects on the ecosystems. Twenty (24) polyethylene pots each containing 7 kg of sandy loam soil mixed with 50 ml of crude oil, were arranged in the Botanical garden of the University of Ilorin, Nigeria, to assess their ability to phytoextract heavy metals in Crude oil-polluted soil. Seeds of Amaranthus hybridus L., Tithonia diversifolia, Abelmoschus esculentus L. and Zea mays were sown in polyethylene containers containing 7 kg of contaminated or Control soil. The containers were arranged in a complete randomized design. Plants were left to grow for two months with regular watering. Plants were harvested, separated into roots and shoots and oven-dried to constant weight. The experimental plants have been able to reduce the concentration of Cu in both soils by about 45% to 85%, Cr in the soil by 92.08% to 96.72%, as the residual concentration varied between 66.00 mg/kg and 99.00 mg/kg, Cd in the soil was reduced to 4.00 mg/kg and 17 mg/kg which represented 96.8% and 86.4% reduction. Tithonia had the highest Pb reduction in crude oilpolluted soil. Ni concentration was reduced by 85.84% by Tithonia planted in crude oil-polluted soil, 94.59% by Amaranthus hybridus planted in Control soil. These show that all the test plants were good phytoextractors of the metals.

A Comparative Study of Deep and Shallow Parsing Approaches to Automated Grammaticality Evaluation
Authors: Aregbesola MK , Ganiyu RA , Olabiyisi SO , Omidiora EO
Published: August 2020

The concept of automated grammar evaluation of natural language texts is one that has attracted significant interests in the natural language processing community. It is the examination of natural language text for grammatical accuracy using computer software. The current work is a comparative study of different deep and shallow parsing techniques that have been applied to lexical analysis and grammaticality evaluation of natural language texts. The comparative analysis was based on data gathered from numerous related works. Shallow parsing using induced grammars was first examined along with its two main sub-categories, the probabilistic statistical parsers and the connectionist approach using neural networks. Deep parsing using handcrafted grammar was subsequently examined along with several of it‟s subcategories including Transformational Grammars, Feature Based Grammars, Lexical Functional Grammar (LFG), Definite Clause Grammar (DCG), Property Grammar (PG), Categorial Grammar (CG), Generalized Phrase Structure Grammar (GPSG), and Head-driven Phrase Structure Grammar (HPSG). Based on facts gathered from literature on the different aforementioned formalisms, a comparative analysis of the deep and shallow parsing techniques was performed. The comparative analysis showed among other things that while the shallow parsing approach was usually domain dependent, influenced by sentence length and lexical frequency and employed machine learning to induce grammar rules, the deep parsing approach were not domain dependent, not influenced by sentence length nor lexical frequency, and they made use of well spelt out set of precise linguistic rules. The deep parsing techniques proved to be a more labour intensive approach while the induced grammar rules were usually faster and reliability increased with size, accuracy and coverage of training data. The shallow parsing approach has gained immense popularity owing to availability of large corpora for different languages, and has therefore become the most accepted and adopted approach in recent times.

A Scalable Health Information System with Appointments Scheduling Facility (A Case Study of National Health Insurance Scheme (NHIS)).
Authors: Aweh O , Olowolagba AA , Ukeagbu SO
Published: August 2020

Waiting time problem, especially for out-patients, is an exceptionally serious issue in public hospitals across the globe. This study observes that with a system that allows subscribers of NHIS to seek medical attention in any NHIS designated hospitals, the waiting time problem will be a major challenge. A perusal of the literature shows that this problem stems substantially from the practice of fixing patients appointments without regard to specific time periods a patient is likely to receive attention on the designated day. The problem is further exacerbated by the practice of fixing such appointments without recourse to the number of doctors who will be available and in some cases, the time to be spent at some facilities. To address this problem, this study modelled an appointment scheduling system that took into consideration the number of doctors, the number of patients and the likely time it will take to complete consultations and the time it will take to complete some procedures or checks at available facility, in some instances. The study then translated this conceptual solution into a formal design using an object-oriented analysis and design methodology. The designed solution was implemented using suitable programming and scripting languages (Hypertext Preprocessor (PHP), JavaScript, HTML5, and CSS), different software tools (MySQL DBMS, Apache Tomcat Webserver) and third party Application Programming Interfaces (API’s). The test results of the developed system vividly demonstrated the proper functioning of the desired features and functions specified.

Este artículo aborda un análisis de la importancia de instaurar un clima organizacional satisfactorio a través de las competencias gerenciales  en el ámbito escolar, tomando en cuenta  factores sociales, económicos, religiosos, culturales, curriculares y políticos, amenazantes del entorno laboral educativo venezolano. Es preocupante el manejo de las instituciones cuando el gerente carece de perspectivas educacionales, visión futurista transformacional  y  sentido de pertenencia  dentro de la institución que dirige,  se pierde el ambiente escolar, se torna  insostenible y crece la desmotivación  por el buen desempeño laboral. Este estudio expone argumentos  para mejorar institucional y personalmente la gestión educativa, enmarcado en el diseño de investigación cualitativa, inspirado en el enfoque descriptivo deductivo de modalidad documental como propuesta educativa. Es prioridad tener la actitud de enfrentar los retos actuales para alcanzar las metas propuestas en el entorno gerencial y buscar los nuevos paradigmas administrativos en el campo de la enseñanza.
Educación inclusiva en la población de estudiantes con discapacidad en el Departamento Sucre Colombia
Authors: Méndez Vergara Luisa Fernanda
Published: August 2020

La escuela, es el reflejo de la sociedad y una de sus características es la diversidad. Desde tiempos remotos, las sociedades han excluido a personas que no consideran iguales, no tienen el mismo comportamiento o no responden igual que ellos. Esta exclusión generalmente resaltaba en el ámbito educativo. Las estadísticas indican que no existen poblaciones que no tengan algún integrante discapacitado, por lo que la inclusión educativa siempre estará vigente. En tal sentido, se hace necesario revisar permanentemente las políticas relativas a la inclusión de la población de estudiantes con discapacidad. En el presente ensayo, se presenta información documental referida a este tema y se analiza desde la mirada a la población del Departamento Sucre de Colombia. Se concluye que, esta población está siendo atendida, pero aún hace falta la revisión de programas y actualización docente ya que persisten indicios de exclusión.

Nghiên cứu này nhằm mục đích làm rõ những đặc điểm và những thách thức trong quản lý, bảo tồn đất ngập nước (ĐNN) tại vùng cửa sông Ô Lâu (CSÔL), tỉnh Thừa Thiên Huế. Kết hợp phương pháp phỏng vấn nông hộ, phỏng vấn cán bộ với phương pháp bản đồ, GIS, viễn thám đã cho thấy, vùng CSÔL có diện tích khoảng 11.000 ha, trong đó, vùng lõi có diện tích là khoảng 433 ha. Theo tiêu chuẩn phân loại ĐNN của Việt Nam, khu vực này có 3 nhóm chính là i) nhóm ĐNN biển và ven biển; ii) nhóm ĐNN nội địa; và iii) nhóm ĐNN nhân tạo. Hiện nay, người dân vẫn đang khai thác các nguồn tài nguyên của vùng CSÔL cho các hoạt động sinh kế. Khoảng 99,6 ha cây bụi tại các bãi bồi đã bị thay thế bởi các loại cây nông nghiệp. Tài nguyên, cảnh quan ĐNN tại CSÔL đang bị biến đổi mạnh mẽ và chức năng sinh thái của khu vực này cũng đang bị suy giảm mạnh. Để phục hồi các chức năng của vùng CSÔL, cần nhiều giải pháp từ cả chính quyền địa phương, người dân và các nhà khoa học. Trong đó, quan trọng nhất là nhận thức của người dân và ý chí của các cấp quản lý trong quá trình hoạch định chiến lược phát triển của vùng.

ABSTRACT

This study aimed at determining the O Lau river’s wetlands (OLRW) characteristics and identifying challenges in wetland management and conservation. By using various methods such as households and local government’s staff interview, mapping, geographic information system (GIS), remote sensing, the research results showed that the OLRW was about 11.000 hectares in which its core zone was about 433 hectares. Following Vietnam’s classification of wetlands, OLRW has three main categories, namely: i) marine and coastal wetlands; ii) inland wetlands; and iii) man-made wetlands. Currently, inhabitants are exploiting OLRW’s natural resources for their livelihood activities. Approximately 99,6 hectares of shrub-dominated wetlands were replaced by agricultural crops. OLRW’s natural resources and landscape have been destroying by human’s activities. In addition, its ecological function has also been reducing. For OLRW’s ecological functional resilience, it is necessary for the local government, inhabitants and sicientists to take countermeasures. The most important keys are inhabitants’ perception and local government’s mind in deciding to make of the development of the strategic plans.
Avaliação dos impactos socioambientais gerados na implantação de pequenas centrais hidrelétricas e usinas hidrelétricas de médio porte

Este trabalho tem como objetivo avaliar o impacto social e ambiental devido à instalação de PCHs e UHE em pequenos municípios, localizada na Região Metropolitana do Vale do Paraíba (RMVALE) no Estado de São Paulo. A pesquisa utiliza um método comparativo de dados relacionados ao desenvolvimento humano, impostos sobre serviços de qualquer natureza, compensação financeira e o produto interno bruto dos municípios, que são disponibilizados de forma on-line pelos órgãos oficiais. Observou-se o aumento das contribuições socioeconômicas com maior expressividade no período das obras, verificou-se também que para o desenvolvimento local a compensação financeira é extremamente importante, uma vez que, este recurso é geralmente aplicado na sociedade, no entanto, pequenas centrais hidrelétricas estão isentas de pagamento e prejudicam estados e municípios. Mas para o socioambiental, ambos os tipos de empreendimentos hidrelétricos causam impactos ambientais, extraem seus recursos hídricos e deixam de possuir outras possíveis atratividades para economia local.
O Proeja e o paradigma da educação problematizadora
Authors: Casa Volmar Meia
Published: August 2020

Este trabalho investiga elementos de diálogo entre o PROEJA e a educação problematizadora de Paulo Freire. Sustentado pela condição hipotética de que o Programa se constitui em uma política pública, porém, carente de uma dimensão educacional democrática e popular, abre-se a discussão para aquilo que o Programa deveria contemplar a fim de avançar na superação de uma visão ainda ingênua da educação de jovens e adultos rumo a sua constituição crítica em termos político, epistemológico e antropológico.
As tendências pedagógicas no contexto da organização, da gestão e do planejamento escolar

Published: August 2020

Uma análise crítica da implementação das tendências pedagógicas no contexto educacional brasileiro mostra que as escolas têm como tarefas a educação e o ensino e aprendizagem dos alunos em relação a conhecimentos, procedimentos, valores e tarefas que se cumprem pelas atividades pedagógicas, curriculares e docentes. Os meios e as condições de consecução desse propósito são assegurados pelas formas de organização escolar e de gestão ao agir de forma interdependente e relacional pois, de modo geral, as diferentes concepções pedagógicas têm como pressuposto que as escolas são instituições sociais que, para cumprirem seus objetivos, necessitam de condições e meios de funcionamento, apesar de haver divergência quanto à escolha e à operacionalização desses meios. Neste artigo, são apresentados elementos para um exame crítico das concepções de organização e gestão escolar no Brasil. Busca-se compreender como se dá a Organização, a Gestão e o Planejamento no âmbito escolar e a relação entre as mudanças políticas e o desenvolvimento dessas concepções em relação às funções e objetivos da escola e à adoção de práticas de organização e gestão. A metodologia utilizada foi a pesquisa bibliográfica, através de pesquisas já realizadas. O estudo constatou que a organização e a gestão escolar têm avançado em nosso país, contudo, ainda há muito a ser feito, pois faltam condições adequadas para que a conjunção dos elementos pedagógicos convirjam para uma real significação do fazer pedagógico. Por esses motivos, o artigo termina com a apresentação de conclusões parciais e com o levantamento da discussão de dilemas sociopedagógicos implicados nos estudos da escola em nossos dias.

O leite deve apresentar parâmetros higiênicos e nutricionais que trazem benefícios aos consumidores. Portanto, o presente estudo teve como objetivo analisar os principais parâmetros físico-químicos e microbiológicos de leites integrais e desnatados, de duas marcas distintas, comercializados na cidade de Paraíso do Tocantins/TO, sendo da marca A e B, ambas possuidoras do SIF (Selo de Inspeção Federal), e assim, julgá-los se aptos ou não para o consumo, tomando como base os Padrões de Identidade e Qualidade (PIQ) específicos para o leite, atestando, assim, sua qualidade. Realizou-se análises de Acidez Total Titulável (ATT), pH e densidade como quantitativas para os parâmetros físico-químicos, enquanto fez-se análises de Identificação de Amido, teste de Peróxidos e Teste de Identificação de Reconstituintes (cloretos) como métodos qualitativos, além de serem realizadas análises microbiológicas de Coliformes Totais e Termotolerantes, Salmonela e Contagem de Microrganismos Mesófilos e Psicrotrófilos de acordo com as normas preconizadas pelo Instituto Adolfo Lutz (IAL). Para as análises microbiológicas, obteve-se resultados satisfatórios, apresentando, assim, ausência de microrganismos, entretanto, as análises físico-químicas apresentaram uma não-conformidade com a Instrução Normativa 62, pois apenas a análise de densidade não foi capaz de identificar a presença de substâncias que estavam contidas nas amostras dos leites desnatados das marcas A e B e o integral da marca B, que deram resultados que indicam a presença de cloretos adicionados fraudulentamente ao produto. Portanto, observou-se através dos resultados obtidos na presente pesquisa que os leites analisados estavam em conformidade com a legislação vigente na parte microbiológica, mas nas análises físico-químicas três amostras apresentaram uma não conformidade, demonstrando, assim, a presença de cloretos nos leites desnatados das marcas A e B e no integral da marca B, logo, compreende-se que essa presença pode acarretar malefícios à saúde dos consumidores.
