The aim of this article is to address the use of smart technology in clothing for people with disabilities. Through the systematic review in the databases (REDIB, DOAJ, Redalyc, BMJ, BVS, Dialnet and PubMed), eleven articles were reached that describe an intelligent technology present in wearable devices designed for the rehabilitation of patients. It highlights a novel and little explored phenomenon in an interdisciplinary field, mainly between Medicine and Computer Science. This review shows that there is still a need for new research that broadens the subject. [ABSTRACT FROM AUTHOR]

The economic and environmental cost of friction in machinery and transport is significantly remarkable being the machine tool one of the most affected. In this sector, the movements are totally affected by the friction originated in the displacements between the guideways and the carriages, which results in terms of precision, energy consumption and component wear. In this line, texturing has proved to be a useful tool to reduce friction. Texturing techniques include frosting and scraping, both manual and costly processes in which the final finish of the workpiece depends on the operator. Other techniques such as laser texturing represent an effective and precise procedure which is at the same time expensive and not applicable in large workpieces. One of the main challenges is to develop techniques capable of producing these textures in a repetitive and economically viable way. In this work, a new assisted dressing technique that allows generating different textures by grinding, controlling the geometry and distribution of these, is presented. This technique allows to create textures in large workpieces, such as the guides of the machine tools and to do it in a repetitive way and in the same machine in which the guide has been ground previously, which entails a reduction in time and costs. This technique has been validated through tribological tests obtaining lower friction coefficients than with manual techniques. [ABSTRACT FROM AUTHOR]

This article presents a state of the art of the research developed on the archaeological sites called concheros in America in the recent years in order to discuss its use as information files.For that purpose, the evidence obtained from these deposits was taken to analyze and contribute to the study of four issues: 1) Populations of America, 2) Paleoenvironment, 3) Paleoecology. Resolution of current problems, 4) Rituality and 5) consumption activity. The high resolution of these deposits and their wide distribution at a spatial and temporal level allow us to use them as files to solve certain archaeological questions based on the application of different methodological lines.

This paper proposes a critical survey about the origins of ethnographic collections of Tierra del Fuego in Italian museums, as well as the historical records these institutions. The historical records of ethnographical museums are paramount archives to unveil the history of the objects, specially its acquisition and the historical context of the Italian institutions at that time. At the same time, ethnographical collections may be considered as documentary archives offering essential information about the social and material productive contexts of every item of the collections. Finally, a second aim of this paper is to offer relevant data about ethnographical Fuegian collections in Italy to Spanish speakers. [ABSTRACT FROM AUTHOR]

This document addresses the arduous problem experienced by some adults in the province of San Luis who deserted the school system several years ago and wish to complete their missing school journey. For the purpose of the work, information obtained from in-depth interviews with adults in the province is used to analyze it from a perspective that is circumscribed from a field that deals with exclusion and inclusion in the educational system. It is relevant to note, in the course of reading the text, that the inclusion or exclusion of these adults into the educational system occurs in a moment in which a new structure of the education system governed by the Federal Education Law is still in force. The line of research that goes through the study has to do with the various strategies that adults use to complete a missing school path. The research is ethnographic in nature, and uses the technique of life histories to know in depth the characteristics of the adults interviewed, their motivations, their expectations in relation to the culmination of their studies. Therefore, the analysis will turn from this approach. In addition, to illustrate the phenomenon the document presents some statistical data that give an account of the current educational situation of the adult population that falls within these characteristics.

This article describes a training experience developed within the framework of the national program of teacher training. The primary purpose was to analyze secondary schools in a context of their meanings and orientations. The experience brought together teachers, directors, pedagogical advisers, and preceptors of secondary schools in the city of Villa Mercedes, Argentina. On one hand, we present an analysis of the representations of secondary school constructed by the participating actors, as well as the concerns and problems regarding current school scenarios; and on the other hand, we describe proposals for intervention that the actors delineated to permit educational practices aimed at accompanying the trajectories of students in transformed school cultures.

The purpose of this study is to compare two patient cohorts with Bankart lesion, one with intraarticular drainage after surgery and another group without drainage. Material and methods: We designed a study cohort for patients with Bankart repair due to relapsing shoulder dislocation; they underwent arthroscopy and were stabilized with suture anchors; intraarticular drainage was used in one group and no drainage was used in a control patient cohort. Thirty-one consecutive patients were operated by the same team. All patients were evaluated at the office using the Rowe, Constant and UCLA scales. The statistical tests used included chi-square, the student-t test or the Wilcoxon rank sum test (nonparametric version). Results: The UCLA median value was 35 (34.5 - 35) in group B and 33 (32.5 - 35) in group A, with p = 0.13. The Rowe test score was 100 (95;100) in group B and 100 in group A (85;100), with p = 0.913. The Constant test score was 96 (88.8 - 98) in group B and 96 (90.5 - 100) in group A with p = 0.535 and no differences. Discussion: This comparative study includes two groups that underwent arthroscopic Bankart repair, one with drainage and another one without drainage. Good results were obtained in both groups. In this study the placement of a postoperative intraarticular drainage did not improve clinical results, as no statistically significant differences were observed between both groups.

Presented in this work are the main characteristics of two points of view used as theoretical frames of reference in studies carried out in mathematical didactics: anthropological and ontosemiotic. The purpose is to highlight analogies and differences between these two approaches and open the door to other theoretical developments. [ABSTRACT FROM AUTHOR]

In this paper, we apply some theoretical notions of the onto-semiotic approach to mathematical cognition and instruction to analyse a lesson on addition and subtraction taken from a Spanish textbook directed to the fifth grade in primary education. Our aims are: (1) to illustrate a technique for analysing mathematics textbooks based on the ontosemiotic approach, and (2) to identify suitability criteria for developing didactical units to study the additive structures in primary education. The results obtained might be useful in the training of prospective mathematics teachers. [ABSTRACT FROM AUTHOR]

In this work we analyze and compare the notions that propose the Theory of Didactic Situations, the Anthropological Theory of Didactic and the Theory of the Conceptual Fields to study the processes of mathematical cognition, as well as the contribution of the Dialectic instrument-object and of the Semiotic Representation Registers. The purpose is to identify the similarities, differences and complements of these theoretical models with the pretension of advancing toward a unified framework for the study of the cognitive and instructional phenomena in mathematics teaching. Also, we will show in what sense the mathematical ontology that is proposed in the Ontosemiotic Approach, along with the notion of semiotic function, can contribute to the progress and coherent articulation of these theories.

The definite integral is a central concept in the applications of calculus to experimental sciences and engineering, and consequently, a relevant didactic research topic. This paper analyses the different meanings of the definite integral by applying theoretical tools of the ontosemiotic approach to mathematical knowledge and instruction, particularly, the interpretation of meaning in terms of systems of operational and discursive practices related to the resolution of types of problems and the algebraization levels model of mathematical activity. Types of problem-situations and configurations of practices, objects, and processes are identified that allow us to characterize and articulate the various partial meanings of the definite integral (geometric-intuitive, as a limit of Riemann sums and cumulative function) as well as its extensions to the case of the double integral (as a particular case of the multiple) and the line, from the most intuitive to the most formal. The analysis allows us to identify the generality degrees of the objects of integral calculus and the role of algebra in the characterization of the meanings of the definite integral, which must be considered in the planning and management of the processes of teaching and learning of integral calculus in engineering degrees.

The number of educational videos available on the internet on the most varied topics is rapidly increasing. These include mathematics videos that cover virtually any type of curriculum content. However, their quality as a learning resource varies greatly. As a result, it is necessary to provide teachers with tools to enable them to analyse the appropriateness of using educational videos, considering the various aspects involved. This paper describes the design, implementation and results of an educational intervention with 93 prospective primary school teachers, focussed on developing their ability to analyse the educational suitability of videos about proportionality. Preliminary analysis of the video revealed significant errors and inaccuracies in the definitions, propositions, and procedures, as well as shortcomings and inaccuracies in the arguments, and so its level of epistemic suitability is rated as medium. However, the majority of the prospective teachers rated its degree of suitability as high in almost all components. Students regard studying didactic suitability and implementing it through components and indicators as positive, believing that this activity facilitates professional reflection. However, mastering this tool requires analysing a greater number and variety of videos and further collective discussion of the results of the analyses performed by the students.

Human Occupation on the Atlantic Coast of Tierra del Fuego During the Late Holocene We present the results of research undertaken at three archaeological sites, Okon XXI, Teis X and Teis XI, located on the Atlantic coast of Tierra del Fuego (Patagonia, Argentina) and dating to the Late Holocene. Teis X and Teis XI are dome-shape shell middens whereas Okon XXI is a shell lens barely visible from the surface.We hope to identify trends in the use of the landscape based on the analysis of processes of production and consumption as well as their intra-site spatial distributions. The morpho-technical and usewear analyses of lithic assemblages allow us to detect similarities in raw material exploitation and artifact manufacture techniques and differences related to spatial organization and activities distributions. Consequently, a heterogeneous use of the coastal landscape is proposed as well as broad, regional circulation of technological knowledge. [ABSTRACT FROM AUTHOR]

The aim of this paper is to show a critical contextualization of technological change and its analysis in hunter/gatherer societies. First of all we describe what factors or causes generate changes in social practices. Subsequently, material criteria (artifact, raw material, site) will be defined to identify technological changes. Finally, it is proposed as a case of study of hunter-gatherer societies that inhabited the Interserrana area (Buenos Aires province) during the middle and late Holocene. [ABSTRACT FROM AUTHOR]

Background: Protein-energy wasting (PEW), defined as the body loss of muscle mass and fat, is an important cardiovascular risk factor in dialysis patients. Diagnosing this condition requires the presence of three characteristics: biochemical (low albumine, prealbumine or cholesterol), body mass reduction (body mass index, weight loss or fat loss) and muscle mass reduction (measured by means of creatinine or arm muscle area). This study aimed at demonstrating that the lean tissue index (LTI) calculated by spectroscopic bioimpedance (SBI) is a valid parameter for the diagnostic of protein-energy wasting. Methods: Cross-sectional study including 1369 patients with two BCM measurements on a six-month delay, analyzing analytic and spectroscopic bioimpedance parameters. Results: The lean tissue index from the BCM (Body Composition Monitor) quantifies the patient's lean mass and it is matched against traditional parameters (plasma albumine) and non-traditional parameters (IRE and PCR) for protein-energy wasting with no alterations from the patient's hydration level. Conclusions: LTI is an easy to obtain parameter of lean mass which can be followed and monitored in order to diagnose risk situations of our patients as it is the protein- energy wasting.

In this paper we present a current research project that is carried out in the uttermost end of South America. The main aim is to analyze the processes of social aggregation between hunter-gatherers and fisher societies who inhabited the Beagle Channel region (Southern Tierra del Fuego Island, Argentina). For that purpose, we develop an ethnoarchaeological approach in order to generate models and hypothesis to confront against the archaeological record. The methodological framework applied to this case study encompasses several lines of research such us: use-wear analysis, residue analysis and zooarchaeology among others. The final goal is to identify the material correlates of the cooperation activities and to obtain a deeper understanding of social relationships between hunter-gatheres comunities.
