Model-Data Streaming for Additive Manufacturing Securing Intellectual Property
Authors: Baumann F. W. , Ludwig T. , Darwin Abele N. , Hoffmann S. , Roller D. 
Published: May 2017

Abstract
With the increased usage and application of 3D printing or additive manufacturing (AM), the question arises of how content providers or creators can ensure their intellectual property on such model data. Similar to other digital media, such object information that is represented in a number of file formats is easy to copy and reproduce lossless. This research combined digital watermarking of physical 3D printed objects with direct streaming of machine code instructions (GCode) for 3D printing. As the user was no longer in possession of a digital model of the object that is to be printed, the replication of the object was made difficult. A digital model was the abstract representation of information of an object that was transformed into a variety of data formats during the production process. From the data available to the user, the reconstruction of the original model was difficult. For this system, a low-cost adaptor was attached to the 3D printer on which the streamed machine instructions were cached. This adaptor controls the 3D printer. This implementation was part of an online 3D printing service published by the authors.
MANAGEMENT OF ENDOCRINE DISEASE: Suicide risk in patients with diabetes: a systematic review and meta-analysis
Authors: Wang Bin , An Xiaofei , Shi Xiaohong , Zhang Jin-an 
Published: May 2017

Background
Previous studies investigating the risk of suicide in diabetes patients reported controversial findings. We did a systematic review and meta-analysis to comprehensively estimate the risk and incidence rate of suicide in diabetic patients.

Methods
PubMed, EMBASE and PsycINFO were searched for eligible studies. Random-effects meta-analysis was used to calculate the relative risk (RR) and the incidence rate of suicide in diabetes patients. We also calculated the proportion of deaths attributable to suicide among diabetes patients.

Results
54 studies were finally included, including 28 studies on the suicide risk associated with diabetes, 47 studies on the incidence rate of suicide and 45 studies on the proportion of deaths attributable to suicide. Meta-analysis showed that diabetes could significantly increase the risk of suicide (RR = 1.56; 95% CI: 1.29–1.89; P < 0.001). Subgroup analysis showed that the RR of suicide associated with type 1 diabetes was 2.25 (95% CI: 1.50–3.38; P < 0.001). The pooled incidence rate of suicide in patients with diabetes was 2.35 per 10 000 person-years (95% CI: 1.51–3.64). The pooled proportions of long-term deaths attributable to suicide in type 1 diabetes patients and type 2 diabetes patients were 7.7% (95% CI: 6.0–9.8) and 1.3% (95% CI: 0.6–2.6), respectively.

Conclusion
This meta-analysis suggests that diabetes can significantly increase the risk of suicide. Suicide has an obvious contribution to mortality in diabetic patients, especially among type 1 diabetes patients. Effective strategies to decrease suicide risk and improve mental health outcomes in diabetes patients are needed.
Neutral Competition forDrosophilaFollicle and Cyst Stem Cell Niches Requires Vesicle Trafficking Genes

Published: May 2017

AbstractStem cell niche competition a common but poorly understood process. One impediment to understanding is a lack of useful niche competition alleles. In...The process of selecting for cellular fitness through competition plays a critical role in both development and disease. The germarium, a structure at the tip of the ovariole of a Drosophila ovary, contains two follicle stem cells (FSCs) that undergo neutral competition for the stem cell niche. Using the FSCs as a model, we performed a genetic screen through a collection of 126 mutants in essential genes on the X chromosome to identify candidates that increase or decrease competition for the FSC niche. We identified ∼55 and 6% of the mutations screened as putative FSC hypo- or hyper-competitors, respectively. We found that a large majority of mutations in vesicle trafficking genes (11 out of the 13 in the collection of mutants) are candidate hypo-competition alleles, and we confirmed the hypo-competition phenotype for four of these alleles. We also show that Sec16 and another COPII vesicle trafficking component, Sar1, are required for follicle cell differentiation. Lastly, we demonstrate that, although some components of vesicle trafficking are also required for neutral competition in the cyst stem cells of the testis, there are important tissue-specific differences. Our results demonstrate a critical role for vesicle trafficking in stem cell niche competition and differentiation, and we identify a number of putative candidates for further exploration.
How accurately does the Brief Job Stress Questionnaire identify workers with or without potential psychological distress?
Authors: Tsutsumi Akizumi , Inoue Akiomi , Eguchi Hisashi 
Published: May 2017

Abstract

Objectives
The manual for the Japanese Stress Check Program recommends use of the Brief Job Stress Questionnaire (BJSQ) from among the program’s instruments and proposes criteria for defining “highstress” workers. This study aimed to examine how accurately the BJSQ identifies workers with or without potential psychological distress.

Methods
We used an online survey to administer the BJSQ with a psychological distress scale (K6) to randomly selected workers (n=1,650). We conducted receiver operating characteristics curve analyses to estimate the screening performance of the cutoff points that the Stress Check Program manual recommends for the BJSQ.

Results
Prevalence of workers with potential psychological distress defined as K6 score ≥13 was 13%. Prevalence of “high-risk” workers defined using criteria recommended by the program manual was 16.7% for the original version of the BJSQ. The estimated values were as follows: sensitivity, 60.5%; specificity, 88.9%; Youden index, 0.504; positive predictive value, 47.3%; negative predictive value, 93.8%; positive likelihood ratio, 6.0; and negative likelihood ratio, 0.4. Analyses based on the simplified BJSQ indicated lower sensitivity compared with the original version, although we expected roughly the same screening performance for the best scenario using the original version.

Conclusions
Our analyses in which psychological distress measured by K6 was set as the target condition indicate less than half of the identified “high-stress” workers warrant consideration for secondary screening for psychological distress.

Published: May 2017

It is well supported that a significant intake of dietary fibre reduces the risk of several chronic diseases. The development of staple foods enriched with fibre is an important contribution to a broader supply of food products with health beneficial effect. In this sense, the objective of this work is the development of bread enriched with psyllium fibre. Four experimental variants obtained by substituting wheat flour with different proportions (0%, 5%, 10%, and 15%) of psyllium husk were used. Bread samples were subjected to physico-chemical examination: humidity, weight, volume and specific volume of bread, crumb porosity and elasticity (according to STAS 91 -2007). The results showed an increment for the hydration capacity of the dough. The volume of the breads decreased as the level of psyllium husk increased, due the dilution of gluten content in the blend and due to the interactions among fiber components, water and gluten. Nevertheless, substitution at 5%, 10% and 15%, gave quality parameters at least as good as for the control sample and produced acceptable bread, in terms of weight, volume and rheological properties.

Authors: PAUCEAN Adriana , MAN Simona , CHIS Simona , SUCIU Roxana , MURESAN Crina 
Published: May 2017

This study aimed to obtain gluten free muffins, with increased nutritional and sensorial value by adding quince flour into a composite flour. To optimize the recipe, four experimental variants using rice, soy, quince flours and starch in different proportions have been proposed. Quince is a rich source of vitamins, minerals, polyphenolic compounds and fibres. The quince flour addition led to muffins with increased content in minerals and very good sensorial properties in terms of taste, flavour, texture and general acceptance. It could be concluded that quince flour is a suitable source for obtaining gluten free muffins. Quince flour addition in aglutenic muffin composite flour up to 10% did not affect negatively their phisico-chemical and sensorial properties.
LINAJES MITOCONDRIALES EN MUESTRAS DE ESQUINA DE HUAJRA (JUJUY, ARGENTINA). APORTES AL ESTUDIO DE LA OCUPACIÓN INCAICA EN LA REGIÓN Y LA PROCEDENCIA DE SUS HABITANTES

Published: May 2017

El sitio arqueológico Esquina de Huajra (centrosur de la Quebrada de Humahuaca) corresponde a una instalación ubicada cronológicamente en la Fase Inca (ca. 500-420 AP) y la tradicionalmente asignada en el noroeste argentino como Hispano Indígena o de primeros contactos con el español (ca. 420-320 AP). Enmarcado en la política económica incaica, habría sido clave en la explotación y distribución de bienes procedentes de las Yungas Orientales. Además, su cultura material sugiere importantes redes de interacción con las tierras altas, planteando interrogantes sobre la conformación poblacional de sus habitantes.En este trabajo se analizan los linajes maternos de individuos de Esquina de Huajra en comparación con otros sitios del centro-sur andino para evaluar su posible origen foráneo, considerando que el reasentamiento de poblaciones fue una práctica imperial recurrente. El ADN fue extraído de piezas dentales de 6 individuos. Se secuenció la Región Hipervariable I del ADN mitocondrial en cuatro individuos hallándose dos A2 y dos C1. La ausencia de B2 discrepa con lo descripto para gran parte de los sitios andinos, donde este haplogrupo es mayoritario. Dos de los cuatro haplotipos se comparten únicamente con otros sitios de la Quebrada de Humahuaca del Período de Desarrollos Regionales (Los Amarillos y San José); pero una variante nodal C1 fue reportada tanto en Juella como en sitios peruanos preincaicos e incaicos. Estos resultados representan un primer aporte al estudio genético de los habitantes de Esquina de Huajra y una evidencia más de los complejos procesos poblacionales en la región andina.
Occupational Therapy intervention intoOsteoArthritis of the Carpometacarpal joint of the thumb in the South African context
Authors: Teuchert Robyn Michelle , De Klerk Susan , Kotzé Marianne , Nieuwoudt Hester Cecilia , Otero Manja , Van Zyl Nicola 
Published: May 2017

Introduction: The carpometacarpal joint (CMCJ) plays a pivotal role in thumb function and essentially, hand function. Investigation concerning the most preferable occupational therapy treatment approach for osteoarthritis (OA) of the CMCJ was therefore indicated. Factors that affect the course of treatment in the South African context were to be identified.Â
Methodology: A descriptive qualitative research design was implemented with a purposive sample of occupational therapists in the Western Cape. Semi-structured interviews were held. These were transcribed and analysed.
Results: A fixed treatment regimen was not followed by participants of the study. Factors contributing to the choice of treatment emerged from the data. These included the source of the referral, aspects of the OT process and the patient. Results demonstrated that it would not be practical to set up a rigid regimen, due to the diverse nature by which OA of the CMCJ presents in patients as well as the contributing factors participants reported to impact intervention.
Discussion: The compilation of a basic guideline is proposed. Each phase of the occupational therapy process according to the stage of OA of the CMCJ should be included to provide meaningful intervention. A proposed guideline is presented based on the results of the study.
Street Vending in South Africa: An entrepreneurial occupation
Authors: Gamieldien Fadia , Van Niekerk Lana 
Published: May 2017

Background: Not all occupations are undertaken entirely by choice. Numerous personal, cultural, economic and social factors influence participation in occupation. In low and middle-income countries, such as South Africa, disparate socio-economic factors might necessitate participation in occupations considered to be 'less desirable'. In this article the occupation of street vending is explored and discussed, with an emphasis on livelihood creation and the meaning and purpose derived from this occupation. Street vending is considered for its potential as a vocational occupation for people facing disabling conditions.
Methods: A collective case study was done comprising six participants who were selected through maximum variation sampling. Data was collected using semi-structured interviews and participant observation. Data analysis took the form of an inductive content analysis.
Results: Occupational therapists need a comprehensive understanding of occupations before making judgements about these, especially when such occupations are not considered mainstream. One such occupation, namely street vending, predominates in the informal economy of South Africa. Findings revealed that, despite hardships associated with this occupation, street vendors adapt to social, political and economic challenges in their context.
Recommendations: A comprehensive approach is needed when appraising the suitability of occupations; one that focuses on the transformative value of occupations in livelihood creation, rather than focusing narrowly on their therapeutic use or potential to contribute to personal meaning. Occupational therapists should adopt a multi-dimensional approach by considering vocational occupations within their social, cultural and political context, whilst keeping the functional requirement in mind and matching these dimensions with impairment or disability if prevalent.

Biomechanics for first year occupational therapy students: Enriching learning using an E-learning resource
Authors: Rudman Elsje Magdalena 
Published: May 2017

ABSTRACT
Teaching and learning requirements of students are constantly changing due to technological development. Teaching methods should keep abreast of technology to continue stimulating learning. E-learning in occupational therapy is developing but is still largely an unexplored field in South Africa.
Method: A cross-sectional non-experimental descriptive design with a pre-test-intervention-post-test, repeated measure timeline method was used to determine change in achievement followed by a survey to determine the experience of the use of an e-learning resource. A convenience sample group of 81 first year occupational therapy students in 2010 and 2011 participated in the study.
Findings: A significant positive change in the performance and compliance of the tool to learning needs of the participants was identified. Experience was found to be positive.
Conclusion: The e-learning tool had a significant effect on learning although some resistance to e-learning was still identified but the majority experienced it as positive.
Key words: electronic media-based learning (e-learning); achievement; occupational therapy students; experience of e-learning.
CONFIGURACIÓN DEL TERRITORIO DESDE LAS IDEAS DE LO VIVO DE ESTUDIANTES DE SEPTIMO DEL INSTITUTO EDUCATIVO DISTRITAL JUANA ESCOBAR
Authors: Pulido Montealegre Erika Hazen 
Published: May 2017

En este trabajo, se muestra una investigación del diario vivir en el contexto escolar del Instituto Educativo Distrital (IED) Juana Escobar. A partir de la cotidianidad se construyó un problema investigativo que, gracias a las experiencias del día a día en la práctica se fue resolviendo, para re-significar la importancia del estudiante, escuchando las voces de aquellos actores, es decir los estudiantes que de una u otra manera permiten que la Labor del ser docente se pueda llevar a cabo (mediar en los procesos de enseñanza aprendizaje). Se construyó y confirmó la hipótesis de que en la escuela se encuentran diversas relaciones entre el territorio y lo vivo, las cuales podrían ser tenidas en cuenta en los procesos de enseñanza y aprendizaje de la biología. De esta manera, desde la investigación se le dio la importancia a lo vivo como objeto de estudio de la biología, pero a su vez un valor distinto al territorio a partir de dicha relación, reconociendo a su vez el papel preponderante que desempeña la enseñanza de la biología para esta nueva mirada del territorio.

Published: May 2017

Se analizan los procesos de modelización desarrollados por tres equipos de estudiantes -futuros profesores de ciencias- mientras construyen el modelo teórico escolar de ser vivo a partir de un experimento sobre germinación. Los datos provienen de videograbaciones de las interacciones de cada equipo, las cuales fueron transcritas y desagregadas analíticamente por episodos considerando los planteamientos del análisis conversacional. Posteriormente realizamos un análisis micro y secuencial de los episodios utilizando como marco de referencia, el modelo teórico escolar de ser vivo y sus componentes, el cual fue representado de manera gráfica en un instrumento que permite visualizar la evolución de los procesos de modelización (entidades del modelo identificadas, tipo de relaciones que establecen entre ellas, …) y de las acciones discursivas implementadas por cada equipo durante la interacción. Los resultados permiten identificar la construcción de tres modelos diferentes, con distintos grados de complejidad y completitud. Dos equipos se quedan más en la identificación y descripción de las entidades que componen el modelo y el establecimiento de relaciones simples entre ellas y sólo uno estudia el modelo a partir de la formulación de hipótesis, el contraste de evidencias y el análisis de los errores, logrando establecer más rela ciones causa efecto entre las entidades. Concluimos que la forma en que cada equipo aprovechó sus experiencia individuales y colectivas y afrontó las tensiones generadas durante la interacción, explica la diversidad de acciones discursivas implementadas y a su vez ratifica el aprendizaje de la ciencia como una práctica social y distribuida.

Authors: Moyano Acevedo Mary Lorena , López Oliva Jeisson Steven 
Published: May 2017

En esta investigación, se presentan las implicaciones pedagógicas que se generan a partir de la implementación de la estrategia educativa nombrada “Bioclub”, con respecto a las prácticas que tiene la población del municipio de Curumaní en el departamento del Cesar (Colombia), con respecto a la tortuga morrocoy. A través de la recolección de información referente a las condiciones socioeconómicas de la comunidad se diseñó la estrategia educativa, siguiendo la premisa del aprendizaje contextualizado. En una segunda etapa se aplicaron las sesiones del Bioclub, donde directamente participó la comunidad, representada por estudiantes del Colegio San José, para la obtención de datos relacionados con las prácticas frente a la especie, así como su reconocimiento biológico y ecológico. Por último, se caracterizan dichas prácticas de la comunidad en relación con la tortuga, las implicaciones referentes al desarrollo de una estrategia educativa enfatizando en los beneficios que tiene el club de ciencias en el proceso enseñanza/aprendizaje, en la construcción del conocimiento, y cómo esto puede generar un cambio positivo en las actitudes de los niños en el cuidado ambiental y la conservación de la biodiversidad colombiana. Por último se desarrolló una Cartilla de conservación construida como resultado del Bioclub, que involucra aspectos relacionados con su biología y ecología, además de una guía encaminada a la cría sostenible, con el fin de minimizar el impacto negativo de las prácticas de la comunidad frente a la especie.

Authors: Piñones Cañete César , Zuleta Ramos Carlos 
Published: May 2017

La presente bio-crónica narra una experiencia educativa, con un grupo de escolares de la ciudad costera de Los Vilos, Región de Coquimbo, Chile. Durante un año, cinco niñas de entre 11 y 12 años, fueron parte de una academia de ornitología, la cual buscó desarrollar la capacidad de observar, reconocer y valorar las aves presentes en su entorno próximo, con miras a generar habilidades científicas y conductas de respeto hacia los humedales costeros del desierto transicional del norte de Chile. Se desarrollaron talleres de aula sobre la historia natural de las aves chilenas y expediciones naturalistas a siete humedales costeros con distintos grados de protección y relevancia ecológica. Se evidenció un fuerte compromiso y entusiasmo en las estudiantes, lo que permitió que asimilaran conocimientos sobre la reproducción y migración de las aves estudiadas. Esto les permitió participar en eventos ambientales y científicos escolares, interactuando con pares de otras escuelas e investigadores en el campo de la Ornitología y la Conservación. Se discuten las implicancias de esta experiencia, en relación al rol que pueden jugar la ornitología escolar, en el cumplimiento de los objetivos de aprendizaje de las bases curriculares de Ciencias Naturales para enseñanza primaria en Chile.

Published: May 2017

La experiencia descrita en estos párrafos es el fruto de una salida de campo, la cual busca conocer los saberes biológicos, educativos y culturales que el corazón de la biodiversidad puede brindar; experiencia que, sin lugar a duda, marcó la vida de cada uno de los participantes como futuros licenciados en Biología, al vivir la experiencia de estaren el Trapecio amazónico durante el segundo semestre del año 2014. Pese a las enormes dificultades que atraviesa la educación pública, es posible tener espacios para construir conocimientos y problematizar el significado de ser maestro de biología en un contexto colombiano, lejos de los imaginarios de la naturaleza prístina, y conscientes de las virtudes y problemáticas que acarrea una ubicación geográfica estratégica como la de esta región, la cual, aunque favorece la biodiversidad del sector y el asentamiento de culturas anfibias, también es foco de los intereses adversos de la sociedad. Esto permite repensar y cuestionarnos sobre el rol de ser maestro en un país como el nuestro.
