En este artículo se describe la experiencia educativa del diseño e implementación del aula virtual de la asignatura Histología II a través de la plataforma Moodle, como complemento de las clases presenciales durante el lapso académico 2016-I (Abril-Septiembre) del plan de estudio Técnico Superior Universitario en Histotecnología dictado por la Universidad de Carabobo. Se trabajó en tres fases, la primera dedicada al diseño del aula mediante nueve unidades temáticas con sus respectivos recursos técnico-pedagógicos, constituidos por documentos descargables de las clases, microvídeos y laminario con cortes histológicos. Una segunda fase dedicada a la implementación del aula con 28 alumnos y una tercera fase de evaluación relacionada con las estadísticas de accesibilidad y uso de los recursos, así como una consulta a los estudiantes sobre el diseño, contenidos y actividades. Los resultados muestran que la utilidad práctica del aula virtual implementada se enfocó en un espacio para la revisión de los contenidos y no como un espacio para la construcción del conocimiento, existiendo estudiantes tímidos frente al cambio. Sin embargo, los recursos diseñados tuvieron un 78,5% de aceptación, mientras que las actividades sumativas propuestas, como crucigramas, infografías y mapas mentales tuvieron un 75% de aceptación. PALABRAS CLAVE: Aprendizaje colaborativo; construcción del conocimiento; morfología microscópica; TIC.   Design and implementation of a virtual classroom in the Histology II subject ABSTRACT This article describes the educational experience of the design and implementation of the virtual classroom of the subject "Histology II" through the Moodle platform, as a complement to the face-to-face classes during the academic period 2016-I (April-September) of the Higher Technical University study in Histotechnology dictated by the University of Carabobo. Work was carried out in three phases, the first one dedicated to classroom design using nine thematic units with their respective technical-pedagogical resources, consisting of downloadable class documents, micro-videos and a laminar with histological sections. A second phase dedicated to the implementation of the classroom with 28 students and a third evaluation phase related to accessibility statistics and use of resources, as well as a consultation with students on design, content and activities. The results show that the practical usefulness of the implemented virtual classroom was focused on a space for the revision of the contents and not as a space for the construction of knowledge, there being shy students in the face of change. However, the designed resources had a 78.5% acceptance, while the proposed summative activities, such as crossword puzzles, infographics and mind maps had a 75% acceptance. KEYWORDS: Collaborative learning; construction of knowledge; microscopic morphology; ICT.

Image Encryption Algorithm

This research presents a method of image encryption that has been designed based on the algorithm of complete shuffling, transformation of substitution box, and predicated image crypto-system. This proposed algorithm presents extra confusion in the first phase because of including an S-box based on using substitution by AES algorithm in encryption and its inverse in Decryption. In the second phase, shifting and rotation were used based on secrete key in each channel depending on the result from the chaotic map, 2D logistic map and the output was processed and used for the encryption algorithm. It is known from earlier studies that simple encryption of images based on the scheme of shuffling is insecure in the face of chosen cipher text attacks. Later, an extended algorithm has been projected. This algorithm performs well against chosen cipher text attacks. In addition, the proposed approach was analyzed for NPCR, UACI (Unified Average Changing Intensity), and Entropy analysis for determining its strength.

Overflow Control

In 1987 the first vortex solids separator facility in Germany was installed for combined sewer overflow (CSO) control. The separation efficiency was optimized in the hydraulic laboratory using scaled down models with artificial tracers to simulate typical sewage particulates. The station has two parallel operating vortex separators and serves a connected and impervious area of about 11 hectares (ha) and 1,500 people. The specific storage volume of the station is 7.2 m3 per ha. Two evaluation programs were conducted. The first evaluation phase noted the operational reliability, hydraulic loads, overflow frequencies and water mass balances. The second phase monitored separation efficiencies. The evaluation showed that vortex solids separators are now ready for use in CSO control.

The case highlights the key concerns and issues an organization may face if its performance management system (PMS) does not serve its intended purpose and how it can cause demotivation and dissatisfaction among employees and result in an overall decline in organizational performance. It also illustrates how employees’ organizational culture and perception can be as important as the system design and can present challenges even if an elaborate system is planned. In the face of increasing turmoil among employees towards management and the decreasing performance of the organization, TECHNO21 decided to change its current PMS, which seemed a difficult but necessary step to achieve the desired performance levels and overall strategic objectives of the organization.

Abstract As part of the strategy for Industry 4.0, this work was developed to outline a methodology that is an important contribution to improve the efficiency and productivity of processes in the ornamental stone extraction industry. Since this sector is important for the Portuguese economy, it is imperative to optimize processes to improve their efficiency in the use of resources, economic valuation, and economic viability. Knowing that one of the main factors to take into account in the feasibility of an exploration of ornamental rocks is the density, persistence and attitude of the discontinuities present in the rock mass, a methodology is proposed that aims to map and characterize the existing discontinuities in the using the latest digital technologies and whenever possible open access (CloudCompare, Stereonet, 3D Block Expert). To this end, work was initially carried out on an active exploration front, identifying and characterizing, through the traditional method (compass and clinometer) and photogrammetry, existing discontinuities and statistically analysing their occurrence. The data analysis shows a variation in the attitude of the discontinuities in a range of -17.72 ° to 14.7 °, this variation corresponding to the strike. As a percentage, there is also a variation in the range of values, from -5.30% to 4.91%, with the reference value being the value obtained by the photogrammetric method. This step was also used to compare the acquired data and verify the variations between them depending on the method used. Photogrammetry was used with another complementary purpose, but very important for the proposed methodology, which is related to the 3D modelling of the fronts and the subsequent projection or extraction of the existing discontinuity plans. The determination of the attitude of the discontinuities was obtained through the manipulation of the point clouds obtained by the photogrammetric modelling, based on the technique of Structure for Motion [SfM] and application of the RANSAC Shape Detection algorithm of the CloudCompare® program, which allows the determination of the attitude of the discontinuities. The characterization of the discontinuities by the photogrammetric method provided the data that was used in the present study to calculate the blocometry in that sector. This was calculated using the 3D BlockExpert software, based on the exploration sequences. The program calculated the predicted volumes in each one, based on a standard dimension for the block of 2.7 × 3.0 × 2.0 meters. As a result, it was possible to compare a number of blocks the value predicted by the 449 modellings and the number of blocks produced 490. This difference of approximately 10% for this order of magnitude is acceptable and confirms the reliability of the proposed methodology. This evaluation using Geotechnologies allows data modelling to be effectively an important process in the planning of the extractive process, and with the development of this approach, it may introduce in a second phase the decision automation of the extractive process, based on economic and commercial criteria and last and third stage, the automation of the extractive process.

The process used to build an autonomous smart home system based on cyber-physical systems (CPS) principles has recently received increased attention from researchers and developers. However, there are many challenges to be resolved before designing and implementing such a system. In this chapter, the authors present a high-level design approach that simulates a smart home system by implementing three levels of the 5C architecture used in CPS modeling and uses well-known machine learning algorithms to predict future user actions. The simulation demonstrates how users will interact with the smart home system to make more efficient use of resources. The authors also present results from analyzing real-world user data to validate the accuracy of prediction of user actions. This research illustrates the benefits of considering CPS principles when designing a home autonomous system that reliably predicts a user's needs.

ABSTRACT Introduction: Studies on autism spectrum disorders (ASDs) have largely focused on children in specific settings. The current scenario of research in ASDs is limited largely to clinic-based case reports, case series, and retrospective chart reviews. The present study is the first population-based prevalence study conducted across rural, urban, and tribal populations in India. Materials and Methods: A cross-sectional two-phase study was conducted cring children in the age group of 1–10 years of age across geographical regions representing rural, urban, and tribal populations. The first phase (screening phase) involved administration of the Hindi version of the Indian Scale for Assessment of Autism. Those identified as suspected of ASD and 10% of all classified as nonsuspects for autism were also evaluated by the clinical team in second phase (evaluation phase). Results: Forty-three children out of a total of 28,070 children in rural, urban, and tribal area in the age group of 1–10 years were diagnosed as cases of ASD yielding a prevalence of 0.15% (95% confidence interval [CI] =0.15–0.25). Logistic regression analysis showed a two times significantly higher risk of diagnosing ASD in rural area as compared to tribal (odds ratio [OR]; 95% CI = 2.17 [1.04–4.52], P = 0.04). Male sex and upper socioeconomic group of head of family/father had a higher risk of getting diagnosed as autism as compared to lower socioeconomic group (OR; 95% CI - 3.23; 0.24–44.28, P = 0.38). Conclusions: Estimation of true prevalence of ASD in India is going to improve policies on developmental disabilities.

Segmentation, feature extraction, recognition and localization are the four stages in range image understanding. Conventional approaches to range image understanding have treated these stages in isolation with a largely bottom-up flow of control and data through these various stages. Strictly bottom-up approaches have proved to be fragile in the face of errors in segmentation due to noise and limitations on sensor resolution and accuracy. Synergetic interaction of these various stages is essential for an image understanding system to exhibit robust behavior. This paper describes the design and implementation of INTEGRA, a range image understanding system that attempts to exploit the synergy between the various stages in the image understanding process. The salient features of INTEGRA are: (i) A synergetic combination of edge- and surface-based segmentation processes that results in more accurate segmentation than would have been possible with either of them alone and (ii) the ability to correct errors made during segmentation in the matching and localization stages. INTEGRA at this time, is limited to recognition and localization of polyhedral objects and is in the process of being enhanced to handle objects with curved surfaces of quadratic order such as spherical, ellipsoidal, cylindrical, and conical surfaces. Experimental results on real range images containing single and multiple polyhedral objects are presented. Future enhancements to INTEGRA are discussed.

Contemporary Education

O artigo é fruto de pesquisa sobre o ensino realizado na escola contemporânea, à luz dos ensinamentos praticados na escola inspirada em Dom Bosco e na maneira como o saber jurídico é construído. Contextualiza-se a “educação contemporânea” e a importância da filosofia pedagógica de Dom Bosco, lançando mão de elementos edificadores de sua filosofia, os quais despertam propostas educacionais em prol dos direitos individuais, sociais e coletivos. A inspiração da educação contemporânea é contemplada nas discussões que envolvem a problemática ético-socioambiental, relacionada às necessidades e interesses do homem, nas esferas dos direitos sociais e dos interesses e direitos difusos e coletivos. Tratar de interesses e necessidades, no âmbito dos direitos humanos e fundamentais, a partir da vertente educacional Salesiana, desperta diálogos atuais entre a educação, a escola, o ensino, e a postura do docente e do discente em face dos problemas socioeducacionais contemporâneos, desafiadores da reconquista da qualidade humana nas relações educacionais, utilizando-se os ensinamentos de São João Bosco. A pesquisa mostra que a qualidade do ensino se realiza com a adoção de postura educacional ativa, incentivadora de conduta de afetividade pelas pessoas e entre as pessoas que participam da relação do ensino-aprendizado, na busca da prática da solidariedade e do respeito incondicional à dignidade dos seres humanos, retornando-se, assim, aos valores da essência humana. Mostra, ainda, que o resgate do dever de cuidar (de tudo e de todos) corrobora o retorno aos valores essenciais do homem, como a caridade e a compaixão, que, entre outros, promovem impulso altruísta de ternura entre os homens, que se perdem constantemente no emaranhado da selva social contemporânea.AbstractThe construction of knowledge , the duty of care and the teachings of St. John BoscoThe article is based on research conducted in the teaching process practiced in contemporary schooling, in light of the teachings practiced in the school inspired by Don Bosco and the way that legal knowledge is constructed. It contextualizes the "contemporary education" and the importance of teaching Don Bosco’s philosophy, using fundamental elements of his philosophy, which arouse educational proposals in favor of individual, social and collective rights. The inspiration of contemporary education is addressed in discussions involving ethical and environmental issues related to the needs and interests of Man, in the spheres of social rights and interests and diffuse and collective rights. It deals with interests and needs in the context of fundamental and human rights, from the Salesian educational aspect, awakens current dialogue between education, school, teaching, and the posture of the teacher and the student in the face of contemporary social and educational problems, challenging the reconquest of human relations in educational quality, using the teachings of St. John Bosco. Research shows that the quality of education is realized by adopting active educational stance supportive of conduct of affection for people and among people who participate in the teaching-learning relationship in the pursuit of practical solidarity and unconditional respect for the human dignity, returning therefore to the values of the human essence. It also shows that the rescue of the duty of care (of everything and everyone) confirms the return to the essential human values such as love and compassion, which among others promote altruistic impulse of tenderness between Men who are lost constantly in the tangle of contemporary social jungle.ResumenLa construcción del conocimiento, el deber de cuidar y las enseñanzas de San Juan BoscoEl artículo se basa en una investigación sobre la enseñanza realizada en la escuela contemporánea, a la luz de las enseñanzas que se practican en la escuela inspirada en Don Bosco y la forma en que el conocimiento jurídico se construye. Contextualiza la "educación contemporánea" y la importancia de la enseñanza de la filosofía de Don Bosco, usando los elementos constructores de su filosofía, que despiertan las propuestas educativas a favor de los derechos individuales, sociales y colectivos. La inspiración de la educación contemporánea se aborda en los debates relacionados con cuestiones éticas y ambientales, relacionados con las necesidades e intereses del Hombre, en las esferas de los derechos e intereses sociales y los derechos difusos y colectivos. Tratar a los intereses y necesidades en el contexto de los derechos humanos y fundamentales, desde el aspecto educativo salesiano, despierta el diálogo actual entre la educación, la escuela, la enseñanza, y la postura del profesor y del alumno en frente de los problemas sociales y educativos contemporáneos, desafiando la reconquista de las relaciones humanas en la calidad educativa, utilizando las enseñanzas de San Juan Bosco. Las investigaciones demuestran que la calidad de la educación se realiza mediante la adopción de la postura educativa activa de apoyo de conducta de afecto hacia las personas y entre las personas que participan en la relación enseñanza-aprendizaje, en la búsqueda de la solidaridad práctica y el respeto irrestricto a la dignidad los seres humanos, volviendo, por lo tanto, a los valores de la essencia humana. También muestra que el rescate del deber de cuidado (de todo y de todos) confirma el retorno a los valores humanos esenciales, como el amor y la compasión, que entre otros promuoven el impulso altruista de ternura entre los Hombres, que se pierden constantemente en la maraña de la selva social contemporánea.Revisor do inglês: Prof. Tadeu GiattiRevisor do espanhol: Prof. Lilian de Souza
