Représenter l’éducation royale au Grand Siècle : variations magistrales dans l’œuvre gravé de François Chauveau
Authors: Teyssandier Bernard
Published: September 2020

Illustrer l’éducation royale dans la France absolutiste du Grand Siècle relève à la fois de l’interdit et de la gageure. Comment un être semblable à Dieu pourrait-il apparaître sous les traits d’un disciple, d’un apprentif  ? Cette difficulté fut habilement contournée par les peintres et les graveurs de l’époque qui s’attachèrent, soit à figurer l’idée d’une initiation, soit à déterminer la perspective d’une pédagogie. Parmi ces artistes, François Chauveau tient assurément une place à part. Mais quel illustrateur fut-il exactement ? Le présent article, consacré aux figures et personnalités dites « magistrales », qui incarnent à la fois le savoir et le pouvoir, emprunte surtout ses exemples à deux ouvrages imprimés : l’ Histoire de France (1647) d’Audin et les Fables choisies mises en vers de La Fontaine (1668). De cette enquête, il ressort que l’imaginaire de François Chauveau, adossé à la culture de son temps, fut essentiellement celui d’un lecteur. Après avoir soumis les textes lui servant de modèles à l’examen critique, Chauveau imagine moins ce qu’il voit qu’il ne donne à voir qu’il lit.
Le Conseil de l’État, l’impact de la loi, l’expert et le gilet jaune
Authors: du Marais Bertrand
Published: September 2020

Le recours à l’expertise par le Conseil d’État, dans sa fonction consultative, peut être appréhendé à travers les méthodes qu’il déploie pour l’évaluation de l’impact des normes. La fonction consultative devrait être le lieu d’excellence du recours à l’expertise. Or, au côté des analyses fournies par les ministères ou les consultations obligatoires, les études d’impact y sont utilisées davantage au soutien du raisonnement juridique que pour évaluer l’effet quantitatif des politiques publiques. Ce relatif désintérêt pour les études d’impact est principalement la conséquence de la jurisprudence du Conseil constitutionnel mais aussi des traits culturels et sociologiques des membres du Conseil. Ce délaissement de l’évaluation peut avoir des effets sur un phénomène comme celui des « Gilets jaunes ».
Le contrôle par la Cour de justice de l’Union européenne des données empiriques soutenant la politique monétaire de la Banque centrale européenne : une analyse de l’affaire Weiss
Authors: Martucci Francesco
Published: September 2020

Alors que la Cour de justice de l’Union européenne opère un contrôle de plus en plus minutieux des données empiriques, la contestation juridictionnelle des opérations non conventionnelles de la politique monétaire menée par la Banque centrale européenne, l’assouplissement quantitatif, semblent être un exemple particulièrement saillant de ce nouvel office. Malgré l’application du contrôle de proportionnalité à la décision de la BCE, la Cour se borne à avaliser l’argumentation de l’institution, en lui reconnaissant un rôle politique, ce qui neutralise, par conséquent, le contrôle des données empiriques.
Tu n’as rien vu à Cologne… Retour sur une affaire embarrassée
Authors: Méadel Cécile , Noûs Camille
Published: September 2020

Que s’est-il passé la nuit de la Saint-Sylvestre 2015 à Cologne ? La couverture de cette nuit a été tardive, mais elle a produit un écho intense, mondial et durable. L’analyse d’un corpus d’articles de presse, avec l’aide d’un outil d’analyse des réseaux textuels, montre que les journaux n’ont jamais pu répondre à la question liminaire. Différents récits ont été proposés qui font proliférer les interprétations sans qualifier d’abord les faits. Sans même en proposer d’images. Deux éléments cruciaux, étroitement entremêlés depuis les premiers communiqués de la police, ont obscurci le débat : les violences sexuelles et les migrants. Aussi y a-t-il eu controverse à la fois sur les responsabilités des faits et sur la liste des victimes. Dans la sphère publique, le procès a été fait bien avant et bien après les événements de cette nuit. L’article montre pourquoi rien n’était visible à Cologne et pourquoi l’enquête, médiatique comme policière, était impossible.

Classification Approach for Sentiment Analysis Using Machine Learning
Authors: Parikh Satyen M. , Shah Mitali K.
Published: September 2020

A utilization of the computational semantics is known as natural language processing or NLP. Any opinion through attitude, feelings, and thoughts can be identified as sentiment. The overview of people against specific events, brand, things, or association can be recognized through sentiment analysis. Positive, negative, and neutral are each of the premises that can be grouped into three separate categories. Twitter, the most commonly used microblogging tool, is used to gather information for research. Tweepy is used to access Twitter's source of information. Python language is used to execute the classification algorithm on the information collected. Two measures are applied in sentiment analysis, namely feature extraction and classification. Using n-gram modeling methodology, the feature is extracted. Through a supervised machine learning algorithm, the sentiment is graded as positive, negative, and neutral. Support vector machine (SVM) and k-nearest neighbor (KNN) classification models are used and demonstrated both comparisons.
A Trauma-Informed Approach to Supervision Using Play Therapy and Experiential Techniques
Authors: Kascsak Theresa M. , Silverberg Sharon
Published: September 2020

The focus of this chapter is to provide an overview of a trauma-informed approach to supervision using play therapy approaches. Given the widespread impact of trauma, there is an increasing urgency for therapists to adopt trauma-informed approaches. The necessity of trauma-informed supervision ensures that the current and future generations of clinicians are trained about trauma to ensure the well-being of not only the profession but also the public. The supervisory relationship is an emotional safe and supportive place in which supervisees develop clinical competency, identity as a professional, and self-care. The use of experiential activities provides an avenue for the transformative processes inherent in supervisee development.

Authors: Alibrahim Ibrahim J. , Mohammed Mohammed H. A. , Kabbani Mohamad S. , Jijeh Abdulraouf M. Z. , Tamimi Omar R. , Alghamdi Abdullah A. , Alhabshan Fahad
Published: September 2020

Background:

Pulmonary arteriovenous malformations (PAVMs) are the major cause of progressive cyanosis in patients palliated with bidirectional cavopulmonary connection (BCPC). The aim of our study is to analyze the occurrence of PAVMs in patients after Kawashima procedure, to study the effect of total cavopulmonary connection (TCPC) on PAVMs, to evaluate the effect of axillary arteriovenous fistula (AAVF) creation on PAVMs, and to study the risk factors for PAVMs.

Methods:

In this retrospective cohort study, all patients with left isomerism and azygous continuation of an interrupted inferior vena cava who underwent Kawashima procedure from July 2001 to December 2017 were included.

Results:

Twenty.six patients after Kawashima procedure were included in our study. PAVMs were diagnosed in 12 patients (46%). Five of these 12 patients underwent TCPC with complete resolution of hypoxemia. Three patients underwent AAVF creation, 2 had complete resolution, while 1 had partial resolution of hypoxemia. Fourteen patients (54%) did not develop PAVMs. Nakata index below 267 mm2/m2and McGoon ratio below 1.9 predicted the development of PAVMs with high sensitivity and specificity.

Conclusions:

PAVMs represent a serious complication in patients who undergo Kawashima procedure. Small size of pulmonary arteries is an important risk factor for the development of PAVMs. Resolution of hypoxemia after TCPC completion supports the hepatic factor hypothesis. Early TCPC completion in these patients may help to avoid the development of PAVMs by restoring the hepatic factor. Resolution of hypoxemia after AAVF creation may support the lack of pulsatile flow hypothesis.

Parastomal hernia is a rare cause of upper gastrointestinal bleeding. We present a case of an 82-year-old lady who presented with a one-month history of abdominal pain associated with coffee ground vomiting and intermittent melena. Gastroscopy showed bleeding from pyloric canal without a definite lesion. Abdominal CT showed herniation of the pre-pyloric and pyloric regions of the stomach into the hernial sac. She underwent a laparoscopic repair with extensive adhesiolysis, reduction of stomach, approximation of defect and placement of a mesh. She made excellent recovery and had no post- operative complications.

Automatic generation control of multi source interconnected power system using adaptive neuro-fuzzy inference system
Authors: Sharma Deepesh
Published: September 2020

LFC (Load Frequency Control) difficulty is created by load of power system variations. Extreme acceptable frequency distinction is ±0.5 Hz which is  extremely intolerable. Here, LFC is observed by PID controller (PID-C), Fuzzy and ANFIS controller (ANFIS-C). To control different errors like frequency and area control error (ACE) in spite of occurrences of load disturbance and uncertainties of system is checked by MATLAB/SIMULINK software. Proposed Controller offers less, and small peak undershoot, speedy response to make final steady state. LFC is mandatory for reliability of  large interconnected power system. LFC is used to regulate power output of generator within specified area to maintain system frequency and  power interchange. Here, two area multi source LFC system is analyzed. ANFIS is utilized for tie-line power deviation and controlling frequency. Proposed controller is compared with other controller and it is found that proposed controller is better than other controller. Proposed controller is better in terms of Robustness. The output responses of interconnected areas have been compared on basis of peak-undershoot, peak-overshoot and settling time (Ts). Result of FLC is compared to that of with classical controller such as proportional derivative plus integral (PID) controller  which suggests that conventional controller is slow.

Activities in building construction industry contribute to air pollution. In this study, gas data from four locations at each three building construction sites in Doha, Qatar were collected and analyzed. Questionnaires were also administered to companies that are involved in building construction projects. The results showed traces of SO2, CO2, CO and NO2 but in amounts below the detrimental limit stipulated by the Ministry of Environment, Qatar. Questionnaire responses revealed that the extraction of raw materials and the energy consumed during construction occur quite often, but strongly implicated dust generated from construction sites and waste disposal, as major factors causing air pollution in the area. It is therefore, recommended that regular monitoring of air should be carried out within building construction sites to aid detection of air contamination. This will serve as a control measure to stimulate catalytic conversion of exhaust, reuse and recycling of waste materials.

Authors: Nwoye E.O. , Fidelis O.P. , Ogunsolu O.
Published: September 2020

Breast cancer is the most common cancer in women worldwide, comprising 16% of all female cancers and early diagnosis remains an important detection strategy. The aim of this study was to design and implement a user-friendly SmartBra. An infra-red (IR) imaging sensor was deployed to determine the temperature profile of the breast for this application. The device was tested with approval from the Health Research Ethics  Committee of the Lagos University Teaching Hospital using healthy persons and persons already diagnosed with different stages of breast cancer. The results showed high sensitivity and specificity with good intra-examiner reliability for absolute values of mean temperature for the right breast and very good reproducibility for the left breast. Data for healthy participants revealed that the difference in absolute temperature between the left and right breast was less than 1oC, while that of the sick (cancer) participants indicated values greater than 1oC. The device is safe and easy to use and therefore can serve as an adjunct diagnostic device for early detection of breast cancer.

Intelligent learning diversity mechanism for unmanned aerial vehicles applications
Authors: Periola A.A. , Obayiuwana E.
Published: September 2020

The increased use of drones and aerial vehicles in applications poses challenges of airspace safety for aviation organizations. It is important to ensure the safety of the airspace when a significant number of unmanned aerial vehicles are deployed by civilian users. A solution that meets this requirement is important to promote innovation in the commercialization of air space for civilian users deploying unmanned aerial vehicle. The discussion in this paper proposes a mechanism that uses artificial intelligence to address this challenge. The proposed mechanism utilizes a low altitude platform (LAP) and entities in terrestrial wireless networks. The low altitude platform (LAP) observes, develops insights and training data (with human aid). The training data is used to develop learning mechanisms which determine the suitable unmanned aerial vehicles flight parameters in different scenarios. The use of the LAP reduces the burden of communicating with terrestrial base stations. The unmanned aerial vehicles have a reduced altitude between the LAPs in comparison to terrestrial base stations. This reduces the free space path loss and rain-induced attenuation. The performance benefit of the proposed mechanism in comparison to existing solution is examined via MATLAB simulations. Evaluation shows that the proposed mechanism reduces the network access costs by up to 90% on average. The proposed mechanism also increases available flight power and improves airspace safety by 37.3% and up to 53.2% on average respectively.

Deploying data mining techniques to gain deeper insight into Nigerian customers' financial activities
Authors: Nwohiri A.M. , Sonubi F.T.
Published: September 2020

Presently, Nigerian banks issue account statements in a tabular flat form. These statements mainly show basic logs of credit and debit transactions. They do not offer a deeper insight into the pure nature of transactions. Moreover, they lack rich mine-able data, and rather contain basic data tables that do not provide enough insights into customers' monthly/weekly/yearly expenses and earnings. In today’s fast-paced digital world, where information processing methods are rapidly changing, customers need not just a basic table of transactions but deeper analysis and detail report of their finances. This paper aims at identifying and addressing these problems by deploying data mining techniques and practices in building an application that helps customers gain a deeper insight and understanding of their spending and earnings over a particular period. Some of the techniques used are classification, statistical analysis, visualization, report generation and summarization.

This work is on remediation of zinc concentration (330.0 mg/kg) in soils from farm settlement at Agbabu community in Ondo State of Nigeria to below maximum allowable 300 mg/kg specified for safe agriculture by standards to ensure that farm products from this farm settlement close to area of mining are safe for human beings. Three indigenous organisms: Bacillus subtilis (B. subtilis), Escherichia coli (E. coli) and Proteus mirabilis (P. mirabilis) were engaged for the remediation study. The organisms were isolated and cultured. Optimum weights of the distinct organisms were inoculated in 4g soils each conditioned with optimum values of pH, temperature, stirring frequency and nutrient in thirty-six 50 ml beakers; and experimented for residual zinc ion at times 5, 10, 15, 20, 25, 30 and 35 days in triplicate with Atomic Absorption Spectrophotometer. Each organism maintained its performance position from day 5 to day 35. Bacillus subtilis took the lead, seconded by P. mirabilis while E. coli lagged. Removal to safe concentration first occurred at 10 days for B. subtilis, 15 days for P. mirabilis and 20 days for E. coli with respective 292.09 mg/kg, 294.37 mg/kg, and 290. 71 mg/kg residual concentrations. The respective residual concentrations and efficiencies at 35 days were 247.33 mg/kg and 25.06 %; 253.47 mg/kg and 23.20 %; and 267.11 mg/kg and 19.07 %. Two-ways ANOVA at (P < 0.05) showed that a combination of 2 or 3 of the organisms would result in lower residual concentration; and relevant performances at shorter times.

Towards green concrete: Response of oyster shell powder-cement concrete to splitting tensile load
Authors: Ubachukwu O.A. , Okafor F.O.
Published: September 2020

The menacing effects of global warming, rising cost of cement, high energy requirements for the production of cement, and the mitigation of environmental pollution have led researchers towards using locally available materials to partially replace cement in concrete or mortar. The concrete produced from such locally available material is called Green Concrete. Few researches have been reported on the usage of Oyster Shell Powder (OSP) to partially replace the Ordinary Portland Cement (OPC). However, none of those reports has reflected the response of such Green Concrete made with Oyster Shell Powder to Splitting Tensile load. In this research, OPC is partially replaced with OSP at the rate of 0%, 5%, 10%, 15%, 20% and 25% in concrete. A total of 72 number of cylindrical metal moulds of 150mm diameter and 300mm height are used to cast the concrete, demoded after 24 hours and cured for 3, 7, 14 and 28 days with three replicates for each curing age and each replacement percentage. The  properties of fresh and hardened concrete were quantified. The results show that the increase of OSP from 0% up to 25% delays the initial and final setting times of cement paste by 25mins and 40mins respectively. It also improves workability by an additional slump of 19mm. In addition, the Splitting Tensile Strength decreased from 1.706N/mm2 for 0% replacement to 1.011N/mm2 for 25% replacement after a three-day curing period, as well as from 2.076.N/mm2 for 0% to 1.388N/mm2 for 25% replacement, after a 28-day curing period. In as much as the Splitting Tensile Strength of concrete is known to be very low relative to its compressive strength; this study has reflected the extent of vulnerability of OSP-Cement concrete to tensile cracking and stress due to loads. Hence, this will result in safer design and loading of such concrete.

Authors: Egbuhuzor O.M. , Madufor I.C. , Nwanonenyi S.C. , Bokolo J.O.
Published: September 2020

Adsorption behaviour and corrosion rate of Sodium carboxymethyl cellulose on aluminium was studied. Different concentration levels of Sodium carboxymethyl cellulose (Na-CMC) solution were applied on several prepared and polished aluminium coupons for a corrosion experiment. These coupons were totally immersed in 100ml of 0.5M solution of Hydrochloric acid (HCl) in an open beaker placed in a water bath at varying temperatures for 2-8hrs respectively. At every specified temperature and time interval, the immersed coupon specimen was withdrawn from the test solution, washed, dried and reweighed. The weight loss being the difference in weight of the specimen before and after immersion in the water bath was recorded for every coupon sample. The effects of concentration, temperature and time on corrosion rate were studied and from the various plots, it was observed that increase in the concentration of the inhibitor decreases the corrosion rate. The study of the adsorption behaviour showed that Na-CMC was physically adsorbed on the aluminium coupons and obeyed Freundlich adsorption isotherm with an activation energy of 32K.83j/mol and heat of adsorption of -18.21Kj/mol . The study also established a relationship between the corrosion rate, CR; concentration, C; temperature, T; and time t, through a mathematical model: CR = 3.8-5*T1.1617 - 0.00052t0.6176 - 0.0013C0.8012, the proportion of variance explained (R2) = 0.8658 (86.58%), From the Results of the experiment and the model, Na-CMC was found to be an active corrosion inhibitor of Aluminium in acidic environment.

Authors: Aliemeke B.N.G. , Oladeinde M.H.
Published: September 2020

Piston is an important internal combustion engine component that works with other engine components to withstand severe stresses and high temperature that are generated in the combustion chambers. Pistons are subjected to a very high mechanical and thermal load which results from extreme pressure cycles and huge forces of inertia caused by extremely high acceleration during the reciprocating motion. The 0.67hp generator piston designed had the values of parameters to be: 51.00mm Piston stroke; 48.85mm piston bore diameter; 3.66kw brake power; 4.87kw indicated power; 11.63Nm engine torque; 3.22mm piston thickness and 9.44cm3 clearance volume. The piston parameter values calculated were found to be in accordance with the recommended range of values in the design and operating data for internal combustion engines.

Development and testing of a capacitive digital soil moisture sensor with printed circuit board as a probe
Authors: Ogwo V. , Ogbu K.N. , Anyadike C.C. , Nwoke O.A. , Mbajiorgu C.C.
Published: September 2020

The quantity and quality of water present in the soil determine to a greater extent the performance of agricultural crops. Real-time determination of moisture content has a greater advantage over the traditional gravimetric method of determining soil moisture content. Thus, this work was based on the design and construction of a cost effective digital capacitive soil moisture sensor for real-time measurement. The moisture sensors comprised four integrated units namely: power supply unit with a 9V DC battery as a power source, sensor unit with a locally sourced Printed Circuit Board (PCB) as the single sensing probe, control unit made up of PIC16f877 microcontroller programmed with a C language and the C source code compiled in Corporate Computer Services Compiler (CSS C) compiler development environment, and a 16x2 display unit which displays the readings in percentage moisture content (%MC) and capacitance (μF) of the soil obtained from the sensor on its screen. Standard gravimetric moisture content was carried out to get the calibration factor which was used to calibrate the sensor for reliability. The validation was done by taking the reprogrammed (calibrated) sensor to the field for further measurement, after which soil samples were collected for further gravimetric analysis. A regression equation was obtained by plotting the moisture content obtained from gravimetric method (%MCG) against that from sensor reading (%MCS) with a high degree correlation coefficient (R2) of 0.998. The developed capacitive soil moisture sensor is cheap, portable, reliable and easy to use even by local farmers.

Pozzolanic and mechanical properties of Date Palm Seed Ash (Dpsa) concrete
Authors: Smith A.S.J. , Xu G. , Garba M.J. , Aliyu M.Y.
Published: September 2020

This paper presents the findings of a research work conducted on how to improve the mechanical properties of concrete using Date Palm Seed Ash (DPSA) as partial replacement of cement. The DPSA used was obtained by controlled burning of date palm seed in a kiln at a maximum temperature of 630oC for eight hours and air cooled afterwards. The ash obtained was sieved through 75μm sieve and its oxide composition analysed using X-ray fluorescence (XRF) procedures. DoE method of mix design was used to produce concrete ingredients for grade 30N/mm2 giving a water-cement ratio of 0.53. The effect of partial replacement of cement with DPSA on cement paste and concrete using 0, 2.5, 5, 7.5, 10, 15 and 20% DPSA was investigated through consistency and setting times tests, workability test, compressive strength test (at 7, 21, 28 and 56 days curing duration), pozzolanic activity index evaluation and water absorption test. Results show that DPSA has high silicon dioxide (45.50%), aluminum oxide (20.75%) and Iron oxide (7.25%). Findings indicate that the consistency and setting times of cement-DPSA paste increased with increase in the replacement of cement with DPSA. The workability of DPSA concrete decreased with increase in cement replacement. Compressive strength test results show that cement can be replaced with DPSA up to 10% as the compressive strength at 10% replacement is 31.5N/mm2 as against the 31N/mm2 of the normal concrete, at 56 days. The pozzolanic activity index result also show that DPSA concrete meets up the minimum requirement of 75% specified by ASTM C618-15. Also, the water absorption capacity of DPSA concrete at the highest replacement (20%) is 11% less than that at 0%.

Characteristics of almond leaf-ash cement stabilized lateritic soil
Authors: Eme D.B. , Ohwerhi K.E.
Published: September 2020

The use of Almond leaf-ash for stabilization purposes has not been given consideration. This paper was thus aimed at evaluating the characteristics of almond leaf-ash for the essence of stabilizing lateritic soil. Sourced lateritic soil was divided into 3 components (unmodified soil sample, cement stabilized soil sample and almond leaf-ash cement stabilized soil sample). Almond leaves were calcined at 250°C and subjected to granulation process. Preliminary tests such as; sieve analysis, Atterberg’s limit and specific gravity tests were done on the unmodified soil sample for the purpose of classification. CBR tests were performed on the cement stabilized soil sample and on the almond leaf-ash cement stabilized lateritic soil sample. A model was developed using the Scheffe’s simplex theory with the cement component fixed at 10% of the dry lateritic soil. Results revealed that the soil was observed to be a Silty Clay soil (A-4) with Plasticity index of 9.24%, therefore requiring stabilization. CBR results for the developed trial mixes were greater than the 15.20% obtained for 10% cement stabilization showing that Almond leaf-ash significantly improved the CBR of the cement stabilized lateritic soil. The CBR model developed for the Almond leaf-ash cement soil also proved adequate from the verification test conducted using χ2 statistics.

Keywords: Almond Leaf Ash, stabilization, California Bearing Ratio, Scheffe’s theory, lateritic soil.

AN ANALYSIS OF POST-CYBERPUNK AS A CONTEMPORARY POSTMODERNIST LITERATURE
Authors: Zaidi Saba , Shahzad Khurram
Published: September 2020

This study is based on Post-cyberpunk in order to highlight the prominence of Postcyberpunk as an emerging representative genre of Postmodern Literature. Technological progress has altered the ontology of being a human in an era of information technology, thus this study aims to critically discuss the issues of id entity and representation. Although ample critical work has been done on genre Postcyberpunk yet this study is unique in a way that it is a collection of different discursive practices related to identity crises presented in selected Post-cyberpunk narratives. It targets to critically analyze the alternations and transformations in representation of identity in the backdrop of Postmodernist Deconstruction of Metanarratives by Lyotard (1984). Apart from the deconstruction of metanarratives this study signifies the relevance of Post-cyberpunk as Postmodernist Literature that represents society through multidimensional discursivity such as capitalism, hypercasaulization, imperialism, religion, economy and technology. This study aims to deconstruct the metanarratives of identity that were considered to be permanent and claimed to be power narratives. It equally represents the deconstruction of center/margin dichotomy by bringing mininarratives into the center. The method adopted for research is SocioCognitve Approach by van Dijk (2008) from Critical Discourse Analysis.

Published: September 2020

Las explicaciones antropológicas de la criminalidad surgen en Italia en la cumbre del positivismo, cuyo liderazgo lo llevaron los médicos, estos buscaron en la animalidad y rasgos primitivos, los estímulos criminales. Posteriormente, se reivindican los estudios incorporando aspectos sociales. El enfoque actual se tornó a lo sociológico, desentrañando que la organización de la vida y su administración pueden acabar con los conflictos y lograr la paz en un mismo espacio común. La filosofía positiva aporta conocimientos de la realidad, cuyo producto debe ser tomado por los políticos para orientar a cambios. Estos estudios han sido tomados por la criminología, nacida de la antropología, para darles orientación de mejoramiento de la realidad social, a pesar de ello, a traviesa por momentos complicados.

La planeación de costo de producción como parte de la gestión empresarial de la empresa, determina la necesidad de realizar estrategias basadas en las decisiones tomadas para establecer los precios y teniendo en cuenta lo que el cliente está dispuesto a pagar por el producto. Este trabajo de investigación se lleva a cabo bajo un enfoque metodológico descriptivo y transversal, donde se utilizó una entrevista respaldada por un cuestionario estructurado que toma como referencia a las Pymes del sector industrial afiliados a CANACINTRA de la ciudad de Hermosillo, Sonora, México, con una fuerza laboral entre 10 y 250 trabajadores y un mínimo de cinco años de actividad. El objetivo es determinar, con base en las opiniones de los gerentes, la importancia de la planificación de costos para la fijación de precios de producto como estrategia de gestión. Los principales resultados muestran que, de acuerdo con las opiniones de los gerentes, la falta de planificación de costos previa para la fijación de precios del producto dentro de un sistema de control de costos de producción puede tener consecuencias en el incremento del costo y la calidad del producto elaborado.

Las máquinas y los mecanismos que utilizamos en la actualidad, son el resultado del estudio y el perfeccionamiento de las máquinas simples desde la prehistoria. Su análisis desde el campo de la ingeniería mecatrónica es importante, ya que los conocimientos necesarios de esta ingeniería, comprenden muchas áreas, entre ellas la ingeniería mecánica. Dentro de la ingeniería mecánica se estudian los análisis dinámicos y cinemáticos de los mecanismos, por lo que, en el plan curricular de ingeniería en mecatrónica de la Universidad Estatal de Sonora, se integra la materia de diseño de mecanismos, como parte de la formación del estudiante de ingeniería en mecatrónica, en donde se entiende, que su estudio y su impacto en la vida cotidiana, puede estar inmerso por escenarios para el estudiante y egresado, que van desde la programación de un robot en el aula de clase, hasta la integración y puesta en marcha de proyectos y sistemas mecatrónicos en la industria.  La materia de diseño de mecanismos se integra por tres elementos de competencia. Estos tres elementos tienen por objetivo utilizar los principios básicos del desplazamiento, aplicar análisis de velocidad y realizar análisis de aceleración en mecanismos de aplicación industrial, por lo que se requiere, dentro de las competencias específicas del curso, el uso de software especializado para el análisis cinemático de los mecanismos. El objetivo de esta investigación es analizar el desplazamiento, la velocidad y la aceleración de diferentes mecanismos, con un enfoque de las competencias requeridas por la materia de diseño de mecanismos de ingeniería en mecatrónica de la Universidad Estatal de Sonora, para demostrar el potencial de aplicación en entornos de enseñanza-aprendizaje, como una simulación del campo profesional, mediante el uso del software Motion de Solidworks y CATIA V5.  La metodología empleada para esta investigación, se plantea en tres puntos: 1) selección de mecanismos a analizar, 2) diseño de mecanismos mediante CATIA y 3) simulación con software Motion.
