In this paper we describe DSpace™, an open source system that acts as a repository for digital research and educational material produced by an organization or institution. DSpace was developed during two years’ collaboration between the Hewlett-Packard Company and MIT Libraries. The development team worked closely with MIT Libraries staff and early adopter faculty members to produce a ‘breadth-first’ system, providing all of the basic features required by a digital repository service. As well as functioning as a live service, DSpace is intended as a base for extending repository functionality, particularly to address long-term preservation concerns. We describe the functionality of the current DSpace system, and briefly describe its technical architecture. We conclude with some remarks about the future development and operation of the DSpace system.

Com o auxílio do formulário eletrônico de pesquisa oferecido pelo aplicativo Google Drive, analisamos a afinidade entre o educador e as tecnologias de informação disponibilizadas atualmente com o objetivo de confrontar tais dados com a imensa variedade de opções apresentadas. Além de caracterizar os sujeitos da pesquisa, as informações obtidas sobre espaço virtual, instrumento computacional de auxílio ao lecionar, recursos para pesquisas científicas, software para organização pessoal e didática e aplicativo baseado no conceito de computação nas nuvens, permitiram o desenvolvimento do instrumento pedagógico EducaTICs. Sessenta e cinco professores responderam à pesquisa, destes, 29 do sexo masculino e 36 do sexo feminino, com idades entre 21 e 63 anos; sendo 63% com tempo de experiência profissional na docência inferior a dez anos. Do total de participantes da pesquisa, 71% atuam na rede pública de ensino e 17% no ensino público e privado. Cinquenta e sete por cento já participaram de formação continuada na área de TIC. A maioria relatou que acessa com maior frequência a página do Google. As redes sociais são usadas por 71% dos respondentes para se relacionarem com amigos. Entre os espaços virtuais mais utilizados está o Blog (32%) seguido pelo site pessoal (12%). O mais utilizado dentre os instrumentos computacionais como auxílio ao professor, para lecionar, são os softwares de apresentação de slides (94%); entre os sujeitos dessa pesquisa, 69% consideram que não utilizam qualquer recurso tecnológico como apoio à organização pessoal. Dos professores que utilizam ferramentas baseadas no conceito de computação nas nuvens, 57% são usuários do DropBox. Os resultados obtidos são representativos para compreensão de que os professores utilizam pouca diversidade nas ferramentas de TICs que podem servir de apoio à sua atividade didática, o que corrobora com o objetivo da ferramenta proposta. / This paper presents a study on an educational product – EducaTICs, an online data repository software that proposes an optimization of the teacher's job to facilitate his search for apps available in the market and which are useful in his daily practice, as an organization staff and teaching materials. Helped by electronic search form offered by Google Drive application, we analyze the affinity between the educator and information technologies currently available in order to confront these data with the immense variety of options presented. In addition to characterizing the subjects, the information obtained on virtual space, computational instrument of aid to teaching, resources for scientific research, software for personal and didactic organization and application based on the concept of cloud computing, enabled the development of pedagogical tool EducaTICs. Sixty-five teachers responded to the survey, of these, 29 males and 36 females, aged between 21 and 63 years; 63% with years of professional experience in teaching less than ten years. Of the participants, 71% work in the public education and 17% in public and private education. Fifty-seven percent have participated in continuing education in Information and Comunication Tecnologies. Most reported that accesses more frequently Google page. Social networks are used by 71% of respondents to engage with friends. Among the most used virtual spaces is the Blog (32%) followed by personal website (12%). The most widely used among the computational tools as an aid to the teacher, to teach, are the slideshow software (94%); among the subjects of this research, 69% consider not using any technology resource in support of personal organization. Teachers using tools based on the concept of cloud computing, 57% are users of DropBox. The results are representative for understanding that teachers use little diversity in ICT tools that can serve to support their teaching activity, which agrees with the objective of the proposed tool.

A tecnologia apóia o processo de ensino de diversas maneiras ao mesmo tempo em que traz desafios para sua utilização. A produção e disponibilização de materiais instrucionais é um dos pilares dos sistemas de ensino, sendo o repositório de objetos de aprendizagem uma forma possível para realização. Essa solução possui poucos anos de existência se comparada a outras, o que impõe desafios para o seu planejamento. Em parte significativa das organizações de ensino observa-se lacuna de conhecimentos nas áreas que envolvem a planificação desse empreendimento. O interesse do estudo e do pesquisador é a integração dos campos de conhecimento envolvidos, nesse caso o técnico, o gerencial, o legal e o pedagógico, para o aumento da capacidade desse processo, na qual se possa identificar as atividades, boas práticas e resultados necessários, em formato flexível, para que se estruture em bases sustentáveis para implantação. O objetivo geral foi o desenvolvimento de um modelo de planejamento para repositório de objetos de aprendizagem. A hipótese da pesquisa é que a formalização, a mobilização de recursos, a aceitação, a integração, a descentralização, o controle, a avaliação ambiental e a interação entre os planejadores estão contemplados no modelo e possibilitam o aumento da capacidade de planejamento do repositório de objetos de aprendizagem em organizações de ensino. De forma a alcançar o resultado requerido foi realizado estudo de múltiplos casos, que decorreram ao longo do ano de 2009 até meados do ano de 2010. A unidade de análise foi o planejamento de repositório de objetos de aprendizagem em organizações com fins educacionais. Realizou-se pesquisa das referências, que envolviam documentos científicos e organizacionais, da área de gestão de projetos e repositório, para que se chegasse a primeira versão da proposta. De forma integrante utilizou-se entrevistas, análise de documentos, observação e instrumento de pesquisa, para a realização de melhorias e o alcance dos resultados e análises quanto a funcionalidade do modelo, com o intuito de melhorar a capacidade do planejamento. O instrumento foi desenvolvido com a utilização de protocolo de modo a ser testado e validado. A hipótese de pesquisa foi confirmada, porém a dimensão mobilização teve concordância interavaliadores baixa, o que demanda atenção especial, de modo que não faltem recursos e pessoas para a realização do trabalho. A pesquisa contribuiu ao proporcionar aos gestores, fases, processos, atividades, boas práticas e questões que possibilitam o aumento da capacidade do planejamento desse tipo de empreendimento. / Technology has supported the teaching process in several ways whereas it poses challenges to its use. The production and availability of instructional materials is one of the pillars of education, and the learning object repository is a possible way to achieve this task. This solution has few years of existence, which poses challenges for planning, In a considerable number of educational organizations there is a knowledge gap in the areas surrounding the planning of learning object repository. The interest of this study and of the researcher is integrating the fields of knowledge involved, which, in this case, are the technical, managerial, legal and pedagogical. The purpose is to increase the capacity of this process, where one can identify the activities, best practices and necessary results, in a flexible format, so that it is structured on a sustainable basis for deployment. The overall objective was the development of a model for planning learning object repository. The hypothesis is that, formalization, resource mobilization, acceptance, integration, decentralization, control, environmental assessment and interaction between planners are included in the model allowing to increase the capacity to plan the learning object repository in educational organizations. ln order to achieve the required result multiple case study was realized, during the year of 2009 until mid-2010. The unit of analysis was the planning of learning object repository in organizations with educational purposes. We performed a review of the literature, involving scientific and organizational documents, in the area of project management and learning object repository, to reach the first version of the proposal. We used interviews, document analysis, observation and research tool for the realization of improvement and achievement of results and analysis regarding the functionality of the model, in order to improve the capacity of planning. The instrument was tested and validated by means of a protocol. The research hypothesis was confirmed, but the dimension resource mobilization had low interrater agreement, which requires special attention, so that there is no lack of resources and people to do the work. The research contributed by providing managers with, phases, processes, activities, best practices and issues that make it possible to increase the capacity of planning this type of project.

As recentes tecnologias de desenvolvimento e distribuição de componentes possibilitaram o aumento do número de componentes disponíveis no mercado. No entanto, eles muitas vezes estão dispersos e não publicados adequadamente para a comunidade de pesquisa e desenvolvimento de software. Encontrar componentes apropriados para solucionar um problema particular não é uma tarefa simples e novas técnicas devem ser desenvolvidas para o reuso efetivo de componentes. Um dos maiores desafios em reusar componentes consiste em classificá-los corretamente para futuras consultas. Classificar componentes para possibilitar uma busca eficaz depende da qualidade das informações adquiridas, que viabilizam melhor precisão e cobertura das consultas ao encontrar componentes reutilizáveis em potencial. Ao mesmo tempo, mecanismos de classificação e busca devem ser fáceis o suficiente para convencer os desenvolvedores a reusar componentes. Este trabalho estuda as técnicas de classificação de componentes de software, repositórios e métodos de busca. é apresentada uma proposta de modelo de classificação de componentes que considera não apenas sua função, mas o negócio onde ele está inserido e seus atributos de qualidade. Um método de preenchimento semi-automático das informações é proposto, de modo a diminuir os custos de classificação. O protótipo REUSE+ foi construído para exemplificar o uso do modelo e do método de classificação semi-automática, de forma a validar a proposta, destacando, por fim, as principais contribuições do trabalho. / The recent developments on components technologies have increased the number of components available to the market. These components are, however, distributed overall the world and not properly advertised to the research and development communities. Finding the appropriate components to solve a particular problem is not very straightforward and new techniques must be developed to effectively reuse components. One of the great challenges in reusing components is concerned with how to actually classify components \"properly\" in order to further retrieve them. Classifying components for effective retrieval depends on acquiring the appropriate information in classification to improve the precision and recall rates in retrieval; finding only the potentially reusable components and not missing potential solutions. At the same time, the classification and retrieval mechanisms must be easy enough to persuade developers to reuse components. This work studies the classification techniques of software components, repository and retrieval methods. Hereafter is presented a proposal of components classification model that considers not just its function, but business and quality attributes. It is proposed a semi-automatic classification mechanism of software information, allowing a cheaper classification. REUSE+ prototype was built to exemplify the use of model and method of semi-automatic classification, allowing the described proposal validation, highlighting at the end the mainly contributions of the work.

A crescente demanda por cursos baseados na World Wide Web (Web) tem imposto uma série de desafios para a área da Tecnologia da Informação e da Comunicação (TIC), em particular quando se considera a Educação apoiada pela Web. Uma das necessidades emergentes da Educação via Web está relacionada com o uso de Objetos de Aprendizagem (OA) dentro de Sistemas Gerenciadores de Curso (SGC). Além de considerar a produção de OA com \"qualidade\", deve-se providenciar seu armazenamento e disseminação de modo eficaz. Entretanto, algumas dificuldades tem sido reportadas por professores envolvidos com cursos pela Web, tais como: o \"custo elevado\" para a autoria do OA; a falta de ferramentas para o compartilhamento desses materiais; e experiências práticas negativas no reúso desses conteúdos em um SGC. Uma primeira proposta para mitigar esses problemas tem sido o desenvolvimento de ferramentas de Repositório de Objetos de Aprendizagem (ROA), visando principalmente facilitar a disseminação dos OA. Apesar do progresso já alcançado, ainda existem várias barreiras para a sua adoção pelos professores, como falta de integração simples entre o SGC e o ROA. Em geral as integrações atuais mostram-se difíceis para um usuário típico. Neste cenário, o objetivo deste projeto é apresentar um ROA inovador, o Repositório Interativo de Conteúdo Digital - iRepositório, cujo modelo prevê uma integração simplificada com um particular SGC e ainda oferece vários recursos para melhorar os processos de ensino e de aprendizagem, como o registro da eficácia educacional do OA. Como contribuição prática os fundamentos do iRepositório foram implementados para um SGC específico, o Moodle. Além de compartilhar OA entre cursos e usuários, ele provê recursos a outro componente do Moodle, o Tarefa Interativa - iTarefa, para armazenamento, classificação e busca de OA ou ainda facilidades para a manipulação dos Módulos de Aprendizagem Interativa (iMA). / The increasing demand for World Wide Web (Web) based courses has imposed some challenges in Information and Communications Technology (ICT) field, in particular when considering the education supported by the Web. One of the emerging needs of education supported by the Web is related to the Learning Objects (LO) usage inside Learning Management Systems (LMS). Besides production of \"good quality\" LO, it must be provided efficient methods concerning their storage and dissemination. However, some difficulties have been reported by teachers of Web based courses: \"expensive costs\" for LO authoring; lack of tools for sharing these materials; and negative practical experiences for reusing them in an LMS. Some proposals to mitigate these problems have been the development of Learning Object Repository (LOR) tools, mainly in order to facilitate the dissemination of LO. Despite the progress already achieved, there are still several barriers for their adoption by teachers such as lack of easy integration between LMS environment and LOR. In general, current integrations are not simple for typical users. In this context, the target of this project is to presents an innovative LOR, the Interactive Repository of Digital Contents - iRepository. Its model provides seamless integration with a particular LMS and offers several resources to help teaching and learning processes, such as registry of LO educational effectiveness. As a practical contribution, the fundamentals of iRepository model were implemented for an specific LMS, the Moodle system. Besides promoting LO sharing among courses and users, it provides resources to other Moodle component, the Interactive Assignment - iAssign, for storage, classification e searching of LO, or even ease management of Interactive Learning Module (iLM).

<p>The farming of insects has been shown to require less land, feed, and water compared to traditional livestock maintenance, while proven to be a source of high-quality protein. The aversion of the Western culture towards edible insects is the major hurdle into their incorporation in the market, unveiling the challenge of integrating them into an existing familiar product. However, studies have shown that merely pulverizing insects into edible “flours” possesses difficulties on itself such as low solubility; severely altering the structural and sensory characteristics of food products upon their addition. Alternatively, scientists have turned to chemical protein isolation techniques to create insect flours with improved functionality. Furthermore, enzymatic proteolysis has shown to aid in extracting the protein bound to insoluble chitin and enhancing techno-functional properties. While this promising technique may open a range of possibilities, no research has been done regarding the incorporation of insect hydrolysates into a food matrix. The purpose of this work was to explore the production of insect hydrolysates with improved techno-functional properties and their impact in the physicochemical, structural, and sensory characteristics on a chosen model matrix: corn tortillas. Crickets (<i>Acheta domesticus</i>) were chosen due to their current relevance in the Western market. </p> <p>Hydrolysates were produced with low (5%), medium (8%), and high (15%) degrees of hydrolysis (DH) either with Alcalase (AL) or Flavourzyme (FL). Alcalase cricket protein hydrolysates (CPH) resulted in higher fat content, which was suspected of possessing surface-activity. Overall, AL peptides displayed significantly (p < 0.05) higher emulsion and foam capacity and stability, suggesting stronger amphiphilic activity. On the other hand, FL peptides were more soluble and had a lower mean molecular weight, demonstrated by their lower glass transition temperatures. Both of these developments may be explained by Alcalase endopeptidase activity and Flavourzyme primarily exopeptidase activity. Treatments resulted in AL-peptides with large and medium size molecular weights that included hydrophobic terminal ends, while FL peptides were smaller and likely contained free amino acids. The difference in molecular weights were seen upon their addition in the raw corn masa, where AL-CPH increased elastic and viscous behavior compared to control, whereas the smaller FL-CPH lowered them due to the plasticizing capability of hydrophilic small peptides. The ability of FL-CPH to interact with corn macromolecules was observed upon thermal treatment, resulting in FL-tortillas with superior strength and extensibility compared to AL-tortillas. In fact, AL-tortillas fragility was seen by the rollability test, showing a complete disintegration of the tortilla structure. Raman spectroscopy further showed the heat-induced intermolecular interactions of FL-peptides with the corn macromolecules. Raman bands at 1049 cm^-1 in FL-tortillas allude to protein-starch complexes and the <i>gauche-gauche</i> region confirmed the presence of disulfide bridges in FL-tortillas, both of these developments were absent in AL-tortillas. Lastly, the formulation of corn chips with these CPH proved to be globally accepted by a population with diverse neophobia levels, confirming theories that consumers are willing to eat insects in an “invisible” format. Flavor and aroma profiles of the chips, quantified by a descriptive analysis study, revealed no commonalities between the two sets of chips. AL-chips were characterized as having corn, shrimp, and roasted peanut notes, while FL-chips were characterized as having tomato, ketchup, and French fry notes. Overall, enzymatic proteolysis was shown to generate cricket peptides with different characteristics, both able to be utilize as a functional ingredient for palatable food products. </p>

Conferencia ETD2017, realizada en Washington DC, 7-9 de Agosto de 2017. / In the last three years Peru has gone through changes in the process of strengthening and disseminating open access, especially regarding digital theses and research or governmental data. Enactment of Law 30035, which establishes and regulates the Open Access National Digital Repository of Science, Technology and Innovation; the Regulations of the National Registry of Research Papers Submitted for Academic Degrees and Professional Titles, RENATI; the National Strategy for Open Governmental Data, Peru 2017-2021; and the Peruvian Open Governmental Data Model constitute all a legal framework that fosters open access. Within this context, since 2013 the Peruvian University for Applied Science, UPC, has implemented policies aimed to foster open access to academic and scientific information, as well to support the use of interoperable technological platforms. As a result, in March of 2013, the UPC Academic Repository was published. And, recently, UPC adopted as mandatory the open access publication of bachelor’s and master’s theses. In the last three years, the UPC Academic Repository ranked among the top in the Webometrics Repositories (Peru), and showed a significant improvement at the Latin American and World level: At the national level, it went from being ranked 13th in January 2013 to 3rd in January 2017. Worldwide, it went from being ranked 1,516th in January 2013 to 849th in January 2017. In Latin America, in January 2017 it was ranked 62nd among 217 repositories. All actions implemented have been complemented with the following strategies: the open access publication of the theses-related data; the use of diverse metadata standards —Dublin Core Qualifiers, ETD-MS, DRIVER 2.0 and OpenAIRE—; the use of the OAI-PMH interoperable protocol; the implementation of identifiers of digital content —DOI and Handle— and identifiers for users —ORCID and Google Profile—; and curation of digital content. Future activities will be oriented to increase visibility of the UPC repository contents. To this end, we have proposed the following: to use DOI in bachelor’s and master’s theses; increase the number of bibliographical records for theses and their data; monitor and assess consultations to UPC theses as shown by national repositories ALICIA and RENATI; and, finally, implement an automated system for managing theses integrated into the UPC Academic Repository.

>Magister Scientiae - MSc / The generation of biomedical research data on the African continent is grow- ing, with numerous studies realizing the importance of African genetic diver- sity in discoveries of human origins and disease susceptibility. The decrease in costs to purchase and utilize such tools has enabled research groups to produce datasets of signi cant scienti c value. However, this success story has resulted in a new challenge for African Researchers and institutions. An increase in data scale and complexity has led to an imbalance of infrastructure and skills to manage, store and analyse this data. The lack of physical infrastructure has left genomic research on the continent lagging behind its counterparts abroad, drastically limiting the sharing of data and posing challenges for researchers wishing to explore secondary analysis, study veri cation and amalgamation. The scope of this project entailed the design and implementation of a proto- type genome archive to support the e ective use of data resources amongst researchers. The prototype consists of a web interface and storage backend for users to upload and browse projects, datasets and metadata stored in the archive. The server, middleware, database and server-side framework are components of the genome archive and form the software stack. The server component provides the shared resources such as network connectivity, le storage, security and metadata database. The database type implemented in storing the metadata relating to the sample les is a NoSQL database. This database is interfaced with the iRods middleware component which controls data being sent between the server, database and the Flask framework. The Flask framework which is based on the Python programming language, is the development platform of the archive web application. The Cognitive Walkthrough methodology was used to evaluate suitabil- ity of the software for its users. Results showed that the core conceptual model adopted by the prototype software is consistent and that actions available to the user are visible. Issues were raised pertaining to user feedback when per- forming tasks and metadata term meaning. The development of a continent wide genome archive for Africa is feasible by utilizing open source software and metadata standards to improve data discovery and reuse.
