El arco de experiencias de la adolescencia Esquivas, estratagemas, embrollos, caparazones y destellos
Authors: Breviglieri Marc 
Published: April 2019

<p>Cuando los adolescentes abandonan la infancia, experimentan una serie de pruebas en público. El espacio intercalado entre las regiones lúdicas de la niñez y el dominio público merece cuestionarse. Dicho cuestionamiento permite idear el equilibrio dinámico que encuentra o no la persona en su modo de entrar en el mundo, entre la localidad de las regiones lúdicas del mundo familiar a las que el adolescente queda unido y la dimensión generalizadora del dominio público en el que planea afirmarse. El paso de la frontera entre el mundo proximal familiar y el dominio público traza entonces un arco experiencial notable: evasiva, estratagema, embrollo, caparazón y destello… La falibilidad y la consolidación progresiva del yo vienen a ser pues, el espacio productivo de comprensión de la propia idea de adolescencia.</p><em> <p> </p><br /></em>
Civilidad social y felicidad del encuentro urbano Las figuras del “viejito” y del “bebé”
Authors: Gayet-Viaud Carole 
Published: April 2019

La sociabilidad urbana fue durante mucho tiempo, y todavía hoy en día lo es, pensada de una manera negativa: ella es presentada en oposición a los espacios de inter-reconocimiento, a su inscripción en el tiempo, a su capacidad a poner en juego la singularidad de las personas. Debido a dicha comparación a todas luces desfavorable, las relaciones furtivas entre individuos anónimos son asociadas con todo aquello que la sociabilidad presenta como lo más factual: la superficialidad evidente de los “códigos”. El presente artículo, producto de una investigación etnográfica realizada en la región de Paris, propone reconsiderar esta perspectiva, con la finalidad de intentar identificar la positividad de los vínculos ligeros en la ciudad. La investigación se focaliza en aquellas situaciones en las que se manifiesta una apertura espontánea hacia los otros, un acercamiento en el que se dan ciertas formas de reconocimiento desinteresado, irreductibles a la salvaguarda de la faz o a la instrumentalización de los lugares o de las personas. <div><div><p> </p></div></div>

Published: April 2019

The aim of this study was to determine the ability performance of FKIP Unimal chemical education students by the using of practicum performance appraisal with self assessment techniques as well as knowing the response of students related to practical performance assessment with self assessment techniques. Self assessment is an assessment of self competence. This study was motivated by the fact that the assessment carried out in practicum activities was still centered on the lecturer and only limited to knowledge that had not been assessed by performance and did not involve students as subjects but only objects of assessment. Type of this study is descriptive qualitative. This study was conducted to describe the findings of the use of performance assessment with self assessment techniques in chemical practicum. The study was carried out at the FKIP Unimal chemical education department for students who took 23 basic chemistry labs. The result was obtained from the instrument of performance appraisal sheets and questionnaire sheets for student responses. Data analysis on the ability of practicum performance and student response of self assessment was analyzed by using percentage techniques. Based on the results of the study showed that the ability of student practicum performance by the assessment of self assessment techniques consisted of very high was about 13.04%; high was about 47.83%; and sufficient was about 39.13%. The student responses to the using of performance appraisal with self assessment techniques showed the results that most students agreed and felt happy with the self-assessment. The conclusion of this study was the students were able to assess performance with self assessment techniques and provide a positive response related to the performance assessment with self assessment techniques.

Published: April 2019

Objective.
The purpose of this study was to understand perceptions of diabetes management responsibilities and the impact of diabetes on day-to-day activities in older adulthood for individuals with type 1 diabetes and their spouses.

Design and methods.
This qualitative content analysis used a constant-compare approach to analyze individual interviews conducted with older adults and their spouses. People with type 1 diabetes (PWD) and their spouses were interviewed regarding how they coped or dealt with diabetes, what activities they carried out or avoided because of diabetes, and how they appraised diabetes as an individual or shared problem.

Results.
Participants (n = 52) included 26 older adults with diabetes (mean age 69 years, SD 2.56 years; 38.5% female) and their spouses (mean age 68 years, SD 5.11 years; 61.5% female). Half of the PWD (50%) and the majority of spouses (76.9%) appraised diabetes as a shared issue. Five themes emerged from the interview data: 1) Perceptions pf PWD of spouse involvement in diabetes care, 2) PWD underestimated the impact of diabetes on their spouse’s daily lives, 3) gendered nature of spouses supporting diabetes management, 4) evolution of diabetes and the relationship across developmental time, and 5) differences in diabetes management among couples.

Conclusion.
Older adults with type 1 diabetes and their spouses have different perspectives regarding diabetes support and responsibility and may not always realize what support is being provided or needed to optimize effective diabetes management. Advancing age with or without diabetes complications may necessitate that spouses provide diabetes support. Diabetes management training for spouses would likely be helpful.

Published: April 2019

IntroductionAnalysis of linked health data can generate important, even life-saving, insights into population health. Yet obstacles both legal and organisational in nature can impede this work.
ApproachWe focus on three UK infrastructures set up to link and share data for research: the Administrative Data Research Network, NHS Digital, and the Secure Anonymised Information Linkage Databank. Bringing an interdisciplinary perspective, we identify key issues underpinning their challenges and successes in linking health data for research.
ResultsWe identify examples of uncertainty surrounding legal powers to share and link data, and around data protection obligations, as well as systemic delays and historic public backlash. These issues require updated official guidance on the relevant law, approaches to linkage which are planned for impact and ongoing utility, greater transparency between data providers and researchers, and engagement with the patient population which is both high-profile and carefully considered.
ConclusionsHealth data linkage for research presents varied challenges, to which there can be no single solution. Our recommendations would require action from a number of data providers and regulators to be meaningfully advanced. This illustrates the scale and complexity of the challenge of health data linkage, in the UK and beyond: a challenge which our case studies suggest no single organisation can combat alone. Planned programmes of linkage are critical because they allow time for organisations to address these challenges without adversely affecting the feasibility of individual research projects.

IntroductionCaregivers of children with health problems experience poorer health than the caregivers of healthy children. To date, population-based studies on this issue have primarily used survey data.
ObjectivesWe demonstrate that administrative health data may be used to study these issues, and explore how non-categorical indicators of child health in administrative data can enable population-level study of caregiver health.
MethodsDyads from Population Data British Columbia (BC) databases, encompassing nearly all mothers in BC with children aged 6-10 years in 2006, were grouped using a non-categorical definition based on diagnoses and service use. Regression models examined whether four maternal health outcomes varied according to indicators of child health.
Results162,847 mother-child dyads were grouped according to the following indicators: Child High Service Use (18%) vs. Not (82%), Diagnosis of Major and/or Chronic Condition (12%) vs. Not (88%), and Both High Service Use and Diagnosis (5%) vs. Neither (75%). For all maternal health and service use outcomes (number of physician visits, chronic condition, mood or anxiety disorder, hospitalization), differences were demonstrated by child health indicators.
ConclusionsMothers of children with health problems had poorer health themselves, as indicated by administrative data groupings. This work not only demonstrates the research potential of using routinely collected health administrative data to study caregiver and child health, but also the importance of addressing maternal health when treating children with health problems.

Published: April 2019

Introduction. The paper discusses the applicability of a riskbased approach in the “personnel-machinery-production environment” system at the facilities running tower cranes through the introduction of IT-technologies that provide open communication of the staff, management team of the operating organizations, and the National Supervisory Authority, to reduce the accident rate. Materials and Methods. An example of a hazardous production facility running tower cranes is given. Materials on the analysis of operational status of tower cranes within the framework of the current legislation in the field of industrial safety are used. The necessity for innovations and transformations, one of whose methods is the risk-based approach allowing for the implementation of all required levels of control, is identified.Research Results. The stages of introduction of the riskoriented approach for tower crane operators implemented through IT-technologies using Web-applications on safety management under the tower crane operation based on the hazard analysis and risk assessment in gamut, algorithmically associated with the electronic block key of its local security system, are determined.Discussion and Conclusions. The application of a risk-based approach in the “personnel-machinery-production environment” system at the facilities running tower cranes through the introduction of IT-technologies will ensure the proper operation of all departments and each participant of the operation, as well as provide Supervisory bodies with an opportunity to access information on the operation for the implementation of control and supervision functions remotely.

Authors: Sobol B. V. , Soloviev A. N. , Vasiliev P. V. , Podkolzina L. A. 
Published: April 2019

Introduction.Early defect illumination (cracks, chips, etc.) in the high traffic load sections enables to reduce the risk under emergency conditions. Various photographic and video monitoring techniques are used in the pavement managing system. Manual evaluation and analysis of the data obtained may take unacceptably long time. Thus, it is necessary to improve the conditional assessment schemes of the monitor objects through the autovision.Materials and Methods.The authors have proposed a model of a deep convolution neural network for identifying defects on the road pavement images. The model is implemented as an optimized version of the most popular, at this time, fully convolution neural networks (FCNN). The teaching selection design and a two-stage network learning process considering the specifics of the problem being solved are shown. Keras and TensorFlow frameworks were used for the software implementation of the proposed architecture.Research Results.The application of the proposed architecture is effective even under the conditions of a limited amount of the source data. Fine precision is observed. The model can be used in various segmentation tasks. According to the metrics, FCNN shows the following defect identification results: IoU - 0.3488, Dice - 0.7381.Discussion and Conclusions.The results can be used in the monitoring, modeling and forecasting process of the road pavement wear.
Arithmetic coder optimization for compressing images obtained through remote probing of water bodies
Authors: Arzumanyan R. V. 
Published: April 2019

Introduction.The fast program algorithm of arithmetic coding proposed in the paper is for the compression of digital images. It is shown how the complexity of the arithmetic coder algorithm depends on the complexity measures (the input size is not considered). In the course of work, the most computationally complex parts of the arithmetic coder algorithm are determined. Performance optimization of their software implementation is carried out. Codecs with the new algorithm compress photo and video records obtained through the remote probing of water bodies without frame-to-frame difference.Materials and Methods.In the presented paper, a selection of satellite images of the Azov Sea area was used. At this, the software algorithm of the arithmetic coder was optimized; a theoretical study was conducted; and a computational experiment was performed.Research Results.The performance of the software implementation of the arithmetic coder is increased by the example of the VP9 video codec. Numerous launches of reference and modified codecs were made to measure the runtime. Comparison of the average time of their execution showed that the modified codec performance is 5.21% higher. The overall performance improvement for arithmetic decoding was 7.33%.Discussion and Conclusions.Increase in the speed of the latest digital photo and video image compression algorithms allows them to be used on mobile computing platforms, also as part of the onboard electronics of unmanned aerial vehicles. The theoretical results of this work extend tools of the average-case complexity analysis of the algorithm. They can be used in case where the number of algorithm steps depends not only on the input size, but also on non-measurable criteria (for example, on the common RAM access scheme from parallel processors).
Method of terminal control in ascent segment of unmanned aerial vehicle with ballistic phase
Authors: Polovinchuk N. Y. , Ivanov S. V. , Zhukova M. Y. , Belonozhko D. G. 
Published: April 2019

Introduction. The solution to the problem on the centroidal motion control synthesis (guidance problem) of an unmanned aerial vehicle (UAV) with long-range capabilities in the boost phase is considered. Control condition requires optimum fuel consumption. The principle of dynamic programming considering the restrictions to the vector modulus of the thrust output is used to solve the problem. The implementation of terminal guidance requires the formation of control as a function of the object state at the end of the ascent phase. The attainment of these boundary conditions determines the further transition to the ballistic flight phase.Materials and Methods. Bellman’s principle of dynamic programming is the most reasonable from the point of view of the implementability of the computationally efficient on-board algorithms and the solution to the problems in the form of synthesis. With natural scarcity of thrust and energy resources on board, this principle enables to obtain solutions free from the switching functions. In this case, the optimal control is a smooth function (without derivative discontinuity) of the current and final parameters of the UAV.Research Results. A new algorithmic method for the synthesis of terminal motion control is developed. Its difference is that the UAV movement control in the ascent phase is formed by the function of the motion actual and terminal parameters. This ensures movement along an energetically optimal trajectory into the given region of space. The problem solution results enable to build closed terminal guidance algorithms for the boost phase of the UAV trajectory with long-range capabilities. Such algorithms have good convergence and injection accuracy due to the prediction of parameters during the flight at a shorter time interval.Discussion and Conclusions. The most preferred is the principle of dynamic programming. It should be used when solving the problem on the centroidal motion control synthesis (guidance problem) of the UAV with long-range capabilities in the boost phase.
Effectiveness of flipped language learning classrooms and students’ perspectives
Authors: Alhamami Munassir , Khan Mohsin Raza 
Published: April 2019

<p>The objectives of this study are to investigate the usefulness of the flipped language learning approach in a reading course, and to understand students’ attitudes and self-efficacy toward it. A quasi-experimental pretest-post-test design was employed. Two treatments were designed, namely, face-to-face and online, using the flipped classroom approach. A total of 43 students participated in the pre-tests and post-tests, administered in both treatments. The data were collected from the results of pre-tests and post-tests. A regression test and t-tests were performed to analyze the data. A significant difference was observed between the students’ results in the pre-tests and post-tests in both treatments. However, the post-test results in both treatments show no significant difference. This finding indicates that both face-to-face and flipped classroom approaches can be equally effective in enhancing the reading skill of Level 1 students. The survey results also indicate that students have more positive attitudes toward the flipped learning approach than society in general does toward it. Accordingly, teachers are advised to select a language-teaching approach that is helpful for students. They should also consider the perspectives of students. Improvement in reading skill is not necessarily attributed to only one of the approaches analyzed in this study.</p>
A importância dos jogos para o ensino de aritmética em manuais de autoria de Theobaldo Miranda Santos
Authors: Schneider Cintia , Da Costa David Antonio 
Published: April 2019

Neste artigo, tem-se por objetivo, compreender o papel dos jogos para o ensino de aritmética, nos manuais pedagógicos ‘Noções de didática especial’, ‘Metodologia do ensino primário’, ‘Manual do professor primário’ de autoria de Theobaldo Miranda Santos, dois destes, publicados nos anos de 1960 e outro em 1952. As análises utilizam aportes da história cultural (CHARTIER, 2010), privilegiando os manuais pedagógicos como fonte de pesquisa (VALENTE, 2008; CHOPPIN, 2009), além dos demais aportes da própria história da educação matemática e ainda Moura (1999) e Mattos (2009), como referencial, no que diz respeito aos jogos para o ensino de aritmética. Theobaldo Miranda Santos foi um importante autor, responsável pela publicação de muitos manuais pedagógicos e sua figura torna-se mais relevante ainda, quando se trata do embate entre católicos e escolanovista em meados do século passado. Quanto aos jogos, Santos indica seu uso, porém sem citar, especificamente, determinado jogo ou apresentar um tutorial. Santos demonstra-se confuso ao definir seu posicionamento quanto aos jogos, porém, vê-se a homogeneidade, nos três manuais, ao afirmar que os jogos são meio de tornar a aritmética mais interessante, divertida e contextualizada com o dia a dia dos alunos. Palavras-chave: Jogos para o ensino de aritmética. Manuais pedagógicos. História da educação matemática.
