The incidence of acute kidney injury has been estimated to be around a fifth of the adult patients during their hospital stays. Sepsis is estimated to be the commonest cause for AKI development in critically-ill patients; contributing to the pathology in 20-50% of the cases. We reviewed some aspects of sepsis-associated AKI. Among the risk factors that may contribute to the development of AKI, age, sex, and the presence of comorbidities as diabetes, heart, and liver diseases were reported as significant factors associated with the development of the condition. The pathophysiology of sepsis-induced AKI is still unclear; however, some authors said that it may be related to the hypoperfusion of the renal tissue and subsequently induced ischemia. This theory was supported by animal studies; however, other investigations on humans reported no association between the two events. On the other hand, we believe that sepsis-induced AKI is probably due to the associated severe inflammatory state and hemodynamic instability are the main accusants. The management of this condition requires early diagnosis and early intervention by managing sepsis. Moreover, vasopressors as epinephrines have proved efficient in managing the shock state, even better than renal replacement therapy.

Laryngeal nerve injury is considered one of the most common complications after thyroidectomy. It is associated with decreased quality of life because it will result in hoarseness of voice and aspiration. Identification of the risk factors and procedures to decrease the injury is crucial for handling laryngeal nerve injury. We searched the MEDLINE database using PubMed. Two independent reviewers reviewed the resulting papers and reviewed them based on our inclusion criteria. Based on the review results, the incidence of recurrent laryngeal nerve injury is higher than the external branch of the superior laryngeal nerve, but it is mainly due to under-reporting of the external branch of superior laryngeal nerve injury. Cancer surgery, surgeon experience, workload, re-operative procedures, and extent of surgery increased the incidence of the laryngeal nerve injury. Handling of these risk factors combined with visual dissection and inspection and/or intraoperative nerve monitoring decreased the incidence of the nerve injury. In conclusion, laryngeal nerve injury is a common post thyroidectomy complication. Anatomical dissection and visual inspection combined with intraoperative nerve monitoring is the most suitable option in high-risk thyroid surgeries.

Published: January 2021

There are numerous algorithms and solutions for car or object detection as humanity is aiming towards the smart city solutions. Most solutions are based on counting, speed detection, traffic accidents and vehicle classification. The mentioned solutions are mostly based on high-quality videos, wide angles camera view, vehicles in motion, and are optimized for good visibility conditions intervals. A novelty of the proposed algorithm and solution is more accurate digital data extraction from video file sources generated by security cameras in Bosnia and Herzegovina from M18 roadway, but not limited only to that particular source. From the video file sources, data regarding number of vehicles, speed, traveling direction, and time intervals for the region of interest will be collected. Since finding contours approach is effective only on objects that are mobile, and because the application of this approach on traffic junctions did not yield desired results, a more specific approach of classification using a combination of Histogram of Oriented Gradients (HOG) and Support Vector Machines (Linear SVM) has shown to be more appropriate as the original source data can be used for training where the main benefit is the preservation of local second-order interactions, providing tolerance to local geometric misalignment and ability to work with small data samples. The features of the objects within a frame are extracted first by standardizing the feature variables and then computing the first order gradients of the frame. In the next stage, an encoding that remains robust to small changes while being sensitive to local frame content is produced. Finally, the HOG descriptors are generated and normalized again. In this way the channel histogram and spatial vector becomes the feature vector for the Linear SVM classifier. With the following parameters and setup system accuracy was around 85 to 95%. In the next phase, after cleaning protocols on collected data parameters, data will be used to research asphalt deformation effects.

Published: January 2021

In this work, a blind watermarking framework for medical images based on Dual-Tree Complex Wavelet Transform (DTCWT) and Non-subsampled Contourlet Transform (NSCT) is proposed. The core idea of this technique is to embed the watermark in the appropriate NSCT sub-band obtained by decomposing the cover image low coefficients purchased from the DTCWT standing on a quantization embedding function, the extraction phase is done without the requirement of the original cover image, what makes it a fully blind process. As clarity and integrity of the retrieved watermark are mandatory, a series of tests were exerted to affirm the robustness of the proposed scheme. The effectiveness of the watermarking is validated by using the peak signal-to-noise ratio (PSNR) and the structural similarity index measure (SSIM) through experiments. Simulation results demonstrate the invisibility of the proposed method and its strong robustness against various attacks, including additive noise, image filtering, JPEG compression, amplitude scaling, rotation attack, and combinational attack. Furthermore, the method in hands outperformance within the quantitative comparisons with other techniques in the literature in terms of rapid execution time, and quality extraction of hidden information, and appropriateness to be integrated for secure exchange in the healthcare sector.
Mitigating the Interference Caused by Pilot Contamination in Multi-cell Massive Multiple Input Multiple Output Systems Using Low Density Parity Check Codes in Uplink Scenario
Authors: Bhardwaj Lokesh , Mishra Ritesh Kumar
Published: January 2021

The effects of pilot contamination (PC) on the performance of multi-cell multi-user massive multiple input multiple output (MC-MU-m-MIMO) system in uplink has been analyzed in this article. In a multi-cell scenario, the channel estimation (CE) at the desired cell using pilot reuse to avoid significant overhead results in poor CE due to PC. The improvement in degraded performance due to the effect of PC has been shown using low Density Parity Check (LDPC) codes. The comparative analysis of performance in terms of variation in bit error rate (BER) with the signal to noise ratio (SNR) for LDPC coded and uncoded information blocks of users has been shown when the number of cells sharing the same frequency band is varied. Further, the expression for sum-rate has been derived and its variation with the number of base station (BS) antennas has also been shown. The simulated results have shown that the LDPC coded scheme performs better than the uncoded counterpart and the sum-rate capacity increases when the strength of channel coefficients between the BS antennas of the desired cell and the users of remaining cells is less.

Application of ontological analysis tools for the formation of calculation models of power supply
Authors:   Yuri Gagarin State Technical University of Saratov (SSTU), Saratov, Russia, Fomin I.N.
Published: January 2021

The concept of intellectual support of the process of automated formation of calculation models of power supply in information systems of energy enterprises, based on the principles of knowledge management, is proposed. The concept includes carrying out ontological data analysis and the formation of the corresponding knowledge bases. The stages of the knowledge management process about the parameters of the calculated power supply models have been decomposed in order to develop tools for their automatic generation in billing systems. Sets of parameters of power supply objects and parameters characterizing the volume of energy consumption, price indicators and parameters for calculating the cost of consumed electricity, which, along with the relations between entities and their functional connections, determine the structure of ontologies, have been determined. For the first time, the definitions of the computational model of power supply are given as a semantic model consisting of a set of basic concepts of the electric power industry, and as a system of knowledge about methods of storing and processing information about the values of energy consumption. An ontology of the process of forming calculation models using the Protégé ontological editor is built. Requirements for the knowledge base of the system for supporting the formation of calculation models in information systems are formulated and the possibility of using data mining technologies with mechanisms for checking the consistency, sufficiency and continuity of knowledge through the use of methods for forming fuzzy rules is substantiated. This makes it possible to substantiate the possibility of applying the principles of fuzzy logic for the automated generation of calculation models of power supply in billing systems.
Compact representation of constraints based on a new interpretation of the concept "tuple of a multi-place relation"
Authors:   Institute for Informatics and Mathematical Modeling – Subdivision of the Federal Research Centre ", Zuenko A.A. ,   Kola Science Centre of the Russian Academy of Sciences (IIMM KSC RAS), Apapity, Russia
Published: January 2021

The article discusses various points of view on the concept of "tuple of a multi-place relation" used in mathematics and information technology. Special attention is paid to an evolution of the concept “tuple” within Constraint Programming technology where the emergence of new interpretations for the concept “tuple” is related with attempts to design more “compact” table representation of qualitative relations comparing with typical relational tables. This “compact” representation can serve as a basis for accelerating qualitative constraint satisfaction procedures. In studied prototype-works, such varieties of table constraints as compressed-tables and smart-tables were proposed. In so doing, the concept of compressed- and smart- tuple substantially differs from traditional concept of tuple of a multi-place relation. However, the known table constraints types are not well suited for modeling and processing all types of quality relations, for example, there are inconveniences when modeling production rules. The article proposes a new type of table constraints – smart-tables of D-type and equivalent transformations rules allowing the initial constraint satisfaction problem to be effectively reduced. The application of the smart-tables of D-type allows in some cases to substantially reduce computer memory consumption comparing with application of the known types of table constraints. In particular, smart-tables of D-types are well suited for modeling production rules, some types of logical expirations and some types of global constraints.

The article analyzes the use of methods of reasoning based on precedents in the management of innovative projects. On the example of electromechanical systems, the use of a fuzzy ontological approach is justified to represent the base of design precedents in the management of innovative projects at all stages of their life cycle. The approach allows for fuzzy granulation of the characteristics of the concepts of an ontological model, typify the process of determining the relevance between current design situations and design precedents solutions, analyzing and identifying typical adaptation options for the design use case base. To expand the possibilities of assessing the relevance between the current design situations and design precedents, it is proposed to use indices of fuzzy compliance, uncertainty in establishing fuzzy compliance and fuzzy inconsistency, based on the calculation of fuzzy relative distance. An original way of analyzing and identifying typical options for adapting design precedents, combining and removing irrelevant design precedents is considered. The process of monitoring the base of design precedents is based on a joint assessment of the values of the proposed indicators for design precedents and consists in checking the conditions for the occurrence of typical situations.

At present, the quality of information support for management is becoming a critical factor in the implementation of the provisions of the Industry 4.0 doctrine, due to which the need to improve the theoretical provisions for managing organizational defects in the implementation of projects for creating hardware and software components of the digital ecoenvironment becomes especially significant. The paper considers a formal model that creates the basis for the formation of a balanced system of the main characteristics of the project, for the case when satisfaction with the properties of the product on the part of the customer and satisfaction with the progress of the project on the part of the contractor are equally important. The basis for the formation of a balanced system of project characteristics is its consideration as a static multi-connected control object. Empirical functional dependencies correspond to direct and cross connections between the input and output parameters of the object. A feature of constructing empirical models is the use of both actual data on budgets and the duration of previously implemented projects, and subjective expert assessments of project participants. The procedure for forming a balanced system of project characteristics is formalized, which makes it possible to automate it. The proposed approach makes it possible to increase the validity of decisions on the feasibility of implementing the project by the forces of the proposed contractor, taking into account the priority of the budget and the duration of the project for the customer.

Published: January 2021

BACKGROUND Breast lesions have gained importance globally due to significant increase in mortality and morbidity associated with breast cancer which is now the commonest malignancy worldwide. Previously, cervical cancer was the most common cancer in Indian women but now the incidence of breast cancer has outnumbered cervical cancer and is the leading cause of death in women due to cancer. Although advances in imaging techniques and increased use of fine needle aspiration cytology have greatly assisted the preoperative evaluation of breast lesions, histopathology remains the gold standard in differentiating benign and malignant lesions. The present study was carried out to know the frequency, age distribution and histopathological profile of neoplastic as well as non-neoplastic lesions of breast. METHODS This retrospective one-year study was conducted in the Department of Pathology at a tertiary health care institute from January 2017 - December 2017. All specimens of mastectomy, lumpectomy, and Tru-Cut biopsies were studied except treated cases of malignancy. Detailed gross examination was done followed by thorough sampling and processing. Tissue sections were stained with haematoxylin and eosin. Different lesions were studied by microscopic examination. Neoplastic lesions were classified based on the WHO (World Health Organization) classification (2012). RESULTS A total of 980 cases was studied out of which 951 were females and 29 were males. The benign neoplasms constituted 329 cases (33.57 %), malignant neoplasms 521 cases (53.16 %) and non-neoplastic lesions 130 cases (13.26 %). In our study fibroadenoma was the most common benign neoplasm (n = 292) and fibrocystic disease formed the major population of non-neoplastic benign lesion (n = 66). Vast majority of cases with malignant neoplasms had invasive carcinoma of no special type (NST) (n = 479). Significantly higher incidence of malignancy was noted in the age group of 41 - 80 years and benign tumours were mostly seen in 2nd and 3rd decade. The ratio of malignant to benign lesions was slightly higher in our study. CONCLUSIONS Large number of carcinoma breast was seen in our study which is a serious concern. So, design and implementation of screening programs and control of the risk factors seem essential. This study emphasizes the importance of early and accurate histopathological diagnosis of breast lesions.

Cortem-lhe a cabeça: a atualidade desse enunciado mutilando corpos de mulheres e subjetividades
Authors: Witzel Denise Gabriel
Published: January 2021

Partimos da centralidade do conceito de enunciado na obra Arqueologia do Saber, de Michel Foucault, articulando-o com as relações inescapáveis entre discurso, corpo e poder, com o objetivo primordial de analisar o acontecimento discursivo do enunciado Cortem-lhe a cabeça, amplamente conhecido a partir dos gritos bradados pela Rainha de Copas em direção a todos os súditos considerados insolentes no clássico Alice no País das Maravilhas, de Lewis Carroll. Interessa-nos a atualidade desse grito dirigido às mulheres dadas como “insolentes”, determinando-lhes sua execução/decapitação. Nossas reflexões privilegiam a rede de sentidos tramada em torno do significante “cabeça” transformado, historicamente, em símbolo de poder e justiça no bojo do poder soberano e, em certa medida, no bojo do poder patriarcal. Nessa direção, descrevemos as materialidades do nosso corpus - constituído por um caso de feminicídio/decapitação relatado no Facebook - em consonância com o espaço de memória que elas convocam, examinando as condições sócio-históricas de existência e de circulação do enunciado Cortem-lhe a cabeça, as posições de sujeito ali apontadas e as especificidades das materialidades que dão corpo aos sentidos. Destacamos, por fim, as articulações que esse enunciado estabelece com a história das mulheres e a memória, (re)produzindo antigas práticas de mutilação de corpos e de subjetividades.

O LAZER NO COTIDIANO: PRÁTICAS COLETIVAS COMO RESISTÊNCIA
Authors: Mendes Francivaldo José da Conceição , Amaral Márcio Douglas
Published: January 2021

Este trabalho discute a noção de cidade, de cotidiano, com centralidade na ocorrência do lazer. Nesse contexto o lazer é entendido como um conjunto de práticas humanas vivenciadas num tempo livre e diferenciado que coexistem temporal e espacialmente nas diferentes sociedades. O objetivo é demonstrar que em diferentes contextos espaciais vigoram variadas práticas que, a despeito de serem consideradas pouco importante, constituem-se em conteúdos significativos da vida social urbana. Essas práticas de lazer existem porque são resistência a uma lógica irredutível de poder. Em outras palavras, são expressões do cotidiano social não capturadas pela racionalidade técnica das formas urbanas e que se encontram dissociadas de um padrão que se baseia no consumo e na efemeridade das relações sociais. A reflexão aqui proposta parte de uma revisão bibliográfica combinada com reiteradas observações em campo que se deram em cidades da Amazônia e de outras regiões do Brasil. Em que pese a predominância da abstração do espaço urbano verificou-se que os sujeitos, nos diferentes tempos e espaços, mantêm uma sofisticada rede de interação e sociabilidade cuja materialidade remete a práticas espontâneas, não racionalizadas, notabilizando caminhos reais para uma cidade, um cotidiano, diferentes para e pelo lazer.

Esta pesquisa problematiza as possíveis dificuldades enfrentadas no percurso formativo dos alunos da Educação de Jovens e Adultos – EJA de uma escola pública no município de Porto Moz – PA, cujo objetivo central foi analisar as prováveis dificuldades encontradas no processo de alfabetização e letramento, a partir da concepção dos alunos. A metodologia utilizada foi a pesquisa de campo com abordagem qualitativa, acrescida de questionário semiestruturado aplicado aos alunos da 2.ª etapa da referida escola, que após analisado evidenciou os seguintes resultados: o processo de alfabetização e o letramento ocorrem desarticulados, evidenciando a existência apenas do primeiro ato, já que esse processo não compreende o mundo sociocultural dos estudantes; estes, por sua vez, percebem a aprendizagem da leitura e da escrita a partir da contextualização das práticas sociais, de modo que o indivíduo se torne, ao mesmo tempo, alfabetizado e letrado. E, embora os estudantes da EJA tenham percepção dessa articulação, reconhecem que na escola, há esforço dos docentes por trabalhar as experiências e as vivências comunitárias e profissionais dos alunos.

Considerações sobre um patrimônio cultural brasileiro indicado à lista da Unesco: o caso do Açude do Cedro nos Monólitos de Quixadá-Ceará
Authors: Da Silva Claudio Antonio Vieira
Published: January 2021

Este trabalho busca investigar os eventuais efeitos decorrentes da indicação de um patrimônio cultural brasileiro à lista de patrimônios da UNESCO, através de uma análise crítica em documentos que pautam na mudança do paradigma patrimonial. A escolha por essa categoria se justifica pela necessidade de refletir criticamente sobre os efeitos atrativos, repulsivos e excludentes que o título concebido pela UNESCO carrega. O objeto empírico trata do Açude do Cedro nos Monólitos de Quixadá/CE, indicado à lista em dezembro de 2014 e com candidatura aceita em janeiro de 2015. O arranjo construtivo e a monumentalidade associados à paisagem natural foram os principais argumentos dados pelo IPHAN para indicação junto à UNESCO. Como etapa metodológica, teve: atividade de campo e análise dos documentos técnicos referentes, a saber: processo de tombamento do açude do Cedro e o parecer da lista indicativa enviado a UNESCO. Por meio da análise desses documentos, foi possível compreender quais os motivadores, os valores e as intencionalidades em torno da indicação a patrimônio mundial. Com base nisso, temos alguns indicativos à cerca dessa patrimonialização, dos valores considerados, dos desdobramentos que esse status carrega e, eventualmente, das dimensões em torno da produção do espaço. Palavras-chave: Patrimônio Mundial. Patrimonialização. Motivadores e intencionalidades. Açude do Cedro.
A Mastery Motivational Climate-Based Service-Learning Program: Physical and Psychosocial Benefits Among Underserved Children
Authors: Kipp Lindsay , Meaney Karen , Griffin L. Kent
Published: January 2021

We explored children’s physical activity level and psychosocial outcomes in a service-learning program. The program, taught by preservice physical educators, engages children in fun activities within a mastery motivational climate (MMC). Forty-two children in grades K–4 wore accelerometers during two 90-min sessions, resulting in 84 data points. Forty-three children age 8 and up completed a postprogram survey assessing motivational climate, perceived competence, and personal and social responsibility. Of those, 27 completed a presurvey as well. On average, children were engaged in light activity for 38.6% and moderate-to-vigorous activity for 26.0% of the program time. Social responsibility improved from pre- to postassessment. Children perceived a high MMC, and regression analyses showed that MMC was positively related to perceived competence, personal responsibility, and social responsibility at the end of the program. Results suggest this program was effective in using an MMC to promote social responsibility while engaging students in light, moderate, and vigorous physical activity.
Social policy and welfare regimes typologies: Any relevance to South Africa?
Authors: Noyoo Ndangwa
Published: January 2021

This paper revisits Esping-Andersen’s welfare regimes typology and applies it to the South African context. To argue its case, it refers to and uses the construct of colonialism of a special type. The paper notes that unlike other African coun- tries, Esping-Andersen’s framework resonates with South Africa’s social policy and welfare regime because of its unique history that partly stems from coloni- alism of a special type. It argues that social policy in present-day South Africa continues to reproduce colonial and apartheid socio-economic outcomes due to path dependency. The paper asserts that path dependency has largely been shaped by colonialism of a special type. The discussion then concludes that South Africa straddles the liberal and social democratic welfare state regimes and classifies it as a hybrid welfare regime.
Casco inteligente de seguridad industrial para la prevención de accidentes y enfermedades ocupacionales

Published: January 2021

La seguridad industrial es un relevante para las empresas debido al uso contante de herramientas, maquinarias y equipos, creando un entorno de trabajo lleno de riesgos y peligros para los trabajadores. Por ello, hay normas que exigen la utilización  de los EPI tales como el casco para prevenir accidentes y enfermedades ocupacionales. Sin embargo, en la actualidad no existe una solución tecnológica en este ámbito que proporcione en tiempo real información tanto al trabajador como al personal médico y al departamento de seguridad industrial, y que alerte al trabajador sin equipos adicionales o la necesidad de personal especializado en mediciones  ambientales como túneles o minas. Por ello, en este trabajo se propone un casco de seguridad inteligente que podría ayudar a reducir el índice de accidentabilidad de los trabajadores. El casco utiliza componentes electrónicos como dispositivos de alerta y puede analizar niveles nocivos de gases, con el fin de prevenir enfermedades ocupacionales a corto y largo plazo a consecuencia de la actividad que realizan los trabajadores.

Se aplicÃ³ un instrumento a 243 personas, utilizando el software de AMOS PASS, en el cual se contemplaron los indicadores del capital humano y desarrollo empresarial, de acuerdo con la hipÃ³tesis las relaciones encontradas entre las varianzas de los constructos indican que existe un valor estadÃ­stico significativo que relaciona a estos constructos. En los resultados se encontrÃ³ que algunas de las variables fueron: la consideraciÃ³n de pertenencia a la empresa, la percepciÃ³n de cÃ³mo los ve la empresa en funciÃ³n de los conocimientos, y, el reconocimiento de que es el capital humano incrementado por parte de la empresa, demostrando que reconoce este valor como gestor del desarrollo empresarial. De esta manera el capital humano se constituye en uno de los principales factores intervinientes en el desarrollo empresarial.

This study aims to identify the role of the educational supervisors in developing the professional performance of social studies teachers in Jordan from a teacher's perspective in the Irbid Governorate of Jordan by identifying the effect of (gender, academic qualification, school level, and years of experience) variables during the academic year 2019/2020. The study used a descriptive and analytical approach on a sample consisted of (120) social studies teachers (60 teachers from each gender) selected randomly from a population of (690) teachers distributed over (487) government schools. A researcher-made questionnaire with (35) response-close questions divided into five areas: planning, teaching methods, relationship with colleagues and the local community, classroom visits, and evaluation on the five-point Likert scale was used as a measuring instrument, and its validity and stability were confirmed. The results showed that both genders agree that there is a major role for educational supervisors in developing the professional performance of social studies teachers, and there is a statistically significant impact at the level of significance (Î±â‰¥0.05) attributable to gender variable in the areas of planning and teaching methods in favor of females. As well as, there is a statistically significant impact at the level of significance (Î±â‰¥0.05) attributable to academic qualifications variable in the areas of planning and teaching methods in favor of postgraduate degree holders. The results also showed that there is an effective role of the educational supervisor in developing the professional performance of social studies teachers from teachersâ€™ perspective in Irbid Governorate of Jordan in the field of planning, relationship with colleagues and the local community in favor of primary schools, and no statistically significant impact of class visits, teaching methods and evaluation attributable to the school level variable. Also, there is a statistically significant impact at the level of significance (Î±â‰¥0.05) attributable to years of experience in planning, teaching methods, and the relationship with colleagues and the local community in favor of the category (more than 10 years) of experience, and no statistically impact of classroom visits and evaluation attributed to years of experience variable. In light of the results, the main recommendation was that, that there is a necessity for reviewing the supervision system by the Ministry of Education to reinforce the educational supervision system and increase the quality of education, thus, a new educational supervision model based on multiple data sources based on guidance should be developed and rapidly adapted to compete with the rapid changes occurring in the educational system, as well, technological and educational changes.

Cet article a pour objectif lâ€™analyse de lâ€™insertion des entreprises miniÃ¨res dans les Niayes Ã  travers lâ€™implication socioÃ©conomique des dÃ©placements des populations et lâ€™impact de la RSE sur le dÃ©veloppement local. Cet article essaie de montrer comment ces populations autochtones du littoral Nord sÃ©nÃ©galais sont dÃ©tachÃ©es de leur territoire et de leurs activitÃ©s productives de subsistance. Depuis lâ€™installation des entreprises miniÃ¨res, la zone des Niayes connait de fortes dynamiques socio-Ã©conomiques sâ€™exerÃ§ant sur son environnement physique et humain Ã  travers lâ€™emprise des sociÃ©tÃ©s sur les espaces agricoles et ceux habitÃ©s. Le dÃ©veloppement du secteur minier induit une exclusion des communautÃ©s locales habitant les sites et qui sont relogÃ©es ailleurs. La documentation faite sur les questions de conflits dans les espaces miniers et des enquÃªtes de terrains et entrevues ont permis de comprendre les dynamiques socio-spatiales et Ã©conomiques dans les zones miniÃ¨res en gÃ©nÃ©ral et dans les Niayes en particulier. Les rÃ©sultats montrent que les Niayes ont fortement connu lâ€™intervention des sociÃ©tÃ©s miniÃ¨res qui causent la modification de cet environnement primitif, la rÃ©duction des espaces agricoles (les parcelles cultivÃ©es sont rÃ©duites) et dÃ©placent des habitations en leur faveur. Cette situation fait des Niayes un espace dâ€™enjeu socioÃ©conomique et Ã©cologique conduisant Ã  lâ€™apparition de divergences conflictuelles autour des sites miniers.
This article aims to analyze the integration of mining companies in the Niayes through the socio-economic implication of the displacement of populations and the impact of CSR on local development. This article tries to show how these indigenous populations of the northern Senegalese coast are detached from their territory and their productive subsistence activities. Since the establishment of mining companies, the Niayes area has experienced strong socio-economic dynamics exerted on its physical and human environment through the influence of societies on agricultural and inhabited areas. The development of the mining sector leads to the exclusion of local communities living on the sites and who are relocated elsewhere. The documentation made on conflict issues in mining areas and field surveys and interviews made it possible to understand the socio-spatial and economic dynamics in the mining areas in general and in the Niayes in particular. The results show that the Niayes have greatly experienced the intervention of mining companies which cause the modification of this primitive environment, the reduction of agricultural spaces (cultivated plots are reduced) and move houses in their favor. This situation makes the Niayes a socio-economic and ecological area of stake, leading to the emergence of conflicting differences around the mining sites.
