The process of generating high quality data for the test and evaluation of diagnostic and prognostic algorithms is still of high importance to the Prognostics and Health Management (PHM) research community. To support these efforts a testbed has been designed, manufactured and commissioned. It has specifically been designed in order to replicate several component degradation faults with high accuracy and high repeatability. This paper documents the design, requirements and the data integrity elements of this benchmark hydraulic system. This document consolidates the process of designing diagnostics testbeds as at present there is a lack of literature on how diagnostics testbeds should be built and is intended to serve as a starting point and quick reference guide for engineers and researchers intending to design and develop a testbed to test and validate PHM applications. The first part of this paper highlights design requirements for all the design aspects for such testbeds with great consideration for industry standards and best practices covering the achievement of electromagnetic compatibility (EMC) and noise mitigation, as well as operators’ safety and equipment protection. The second part of the paper put great emphasis on data integrity elements of the data generated by this testbed (describing the system under healthy and faulty conditions) before it is actually used for system characterization or by diagnostics and prognostics algorithms.

Abstract Rice grain length (GL) directly affects the yield and quality of this species. Very few GL-related genes cloned are applied in production because their yield-increasing effect was not obvious. In this study, the two bulk-DNA pools (L-pool and S-pool) and their parents’ (KJ01 and Huaye 4) DNAs were subjected to high-throughput sequencing. After assessing the quality of the data, we obtained a total of 100.22 Gb of high-quality data; the average coverage depth was 55x, and the genome coverage was 96.51%. After combining the association results of the ED and SNP index methods, we mapped the GL genes to a 0.34 Mb “hotspot” region on chromosome 3, which contains 37 genes related to various traits. The 37 predicted genes were further analyzed by the use of the Gene GO, COG database and so on. Thirty-three genes were annotated by GO functions. According to the GO annotations, three genes whose molecular function involved in the plasma membrane and intracellular membrane-bound organelles were detected via CRISPR/ Cas9 editing technology. ORF33 was verified to regulate GL and was the target gene qGL3.5. These results provides a new gene resource for rice grain shape breeding and a starting point for functional characterization of the wild rice GL gene.

The overall objective of this project is research-based development, implementation and evaluation of a game-based learning concept to be used in the veterinary education. Herd visits and animal contact are essential for the development of veterinary competences and skills during education. Yet veterinary students have little occasion to reach/attain a proper level of confidence in their own skills/abilities, as they have limited “training-facilities” (Kneebone & Baillie, 2008). One possible solution mightbe to provide a safe, virtual environment (game-based) where students could practise interdisciplinary clinical skills in an easily-accessible, interactive setting. A playable demo using Classical Swine Fever in a pig herd as an example has been produced for this purpose. In order totailor the game concept to the specific veterinary learning environment and to ensure compliance with both learning objectives and the actual learning processes/procedures of the veterinary students, the project contains both a developmental aspect (game development) and an exploration of the academic (scholastic) and profession (practice) oriented learning context. The initial phase of the project was a preliminary exploration of the actual learning context, providing an important starting point for the upcoming phase in which I will concentrate on research-based development, implementation and evaluation of a game-based virtual environment in this course context. In the academic (scholastic) and profession (practice) oriented learning context of a veterinary course in Herd Health Management (Pig module),ethnographic studies have been conducted by using multiple data collection methods; participant observation, spontaneous dialogues and interviews (Borgnakke, 1996; Hammersley & Atkinson, 2007). All courserelated activities in the different learning spaces (commercial pig herds, auditoriums, post-mortem examinations, independent group work) were followed.This paper will describe the project and it will focus in particular on the initial exploration of the veterinary learning context in terms of theory, empirical data and the methods.

A test bed type astronaut maneuvering unit was designed and evaluated with the assistance of Martin Marietta's six degree of freedom simulator. Four different control modes were developed for this unit for test and evaluation inside Skylab's 22 foot diameter orbital workshop. The orbital tests have provided the experience and technology base necessary for space Shuttle and space station astronaut maneuvering unit design requirements. This paper is an overview of the M509 experiment hardware, procedures, and results with emphasis on the comparison between on-orbit test results and the six degree of freedom simulator. The simulator was used to develop the unit's design requirements, evaluate the control logic parameters, and for developing maneuvers and training the crew. The simulator will also be flown by the Skylab crews in May for post flight evaluation and simulator calibration. (Films of the simulations and on-orbit flight are available as part of this presentation.)

An invalid is a person with physical or mental abnormalities which hinders their ability of doing normal human activities. One of the aforementioned abnormalities is the loss or malfunction of a body part or organ, such as the human leg. Problems brought about by this disability could be alleviated by the use of prosthetic limbs to restore normal bodily functions [1]. While there are many needs for leg prosthetics in Indonesia, the price of commercially available prosthetic is prohibitively high for most amputees. The current available affordable prosthetics are very basic and employ monocentric knee joints. Here an attempt is made towards acquiring an optimal design of an affordable prosthetic leg using previously developed four-bar knee joint [2,3]. The design is carried out by implementing a systematic design method to arrive at an affordable, yet ones with better performances. The procedure involves a rubric and analyzing various alternatives to arrive at an optimal design conclusion. The evaluation objective is to maximize the performance of the leg and knee prosthetics through an extensive analysis with considerations from various stakeholders, including the potential users, fabricator, and hospitals in Indonesia [4]. The final design of the leg consists of a composite socket, an aluminum pylon, and a solid-ankle cushioned-heel foot design. Its components are modular and compatible with prosthetic industry standards. The knee is made of a combination of polymers and stainless steel and employs a polycentric mechanism in order to satisfy design requirements while keeping costs low [4,5]. The leg and knee were then fabricated according to the analysis results. The total cost of fabrication is approximately 5.5 million IDR, significantly cheaper than commercial prosthetics. The prototype is then tested and examined using a gait analysis system previously developed at Institut Teknologi Bandung by the Biomechanics Research Team [6]. The results show satisfactory performance, albeit with a host of potential improvements.

Seals are widely used in hydraulic power systems to prevent fluid leakages. However, several types of degradation can decrease the performance of these components such as wear, which induces changes in the geometry of the cross-section area, influencing their sealing capability. Over the years, their behaviour has been primarily investigated with several theoretical and experimental researches. All these valuable results can be considered as a starting point for further investigations on the interaction between seals and the complete hydraulic equipment and on the root of seals degradation. This article proposes a physical model of performance degradation acting on dynamic seals of an electro-hydraulic servo-actuator (EHSA) ram for primary flight controls. In this article, a dynamic non-linear seals degradation model has been developed, based on the Hart-Smith hyperelasticity model, which physically describes the stress and strain of “rubber-like” materials. Similarly, wearing has been assessment by using the Archard’s equation. Furthermore, different operating temperatures have been considered to analyze the effect on seals performances. The integration between the mentioned seals degradation model and the high-fidelity model of the complete EHSA allows to evaluate the influence of various wear levels on the actuator behaviour. This research activity is inserted into a more extensive project of Prognostic and Health Management (PHM) of EHSAs. The results of the proposed simulations reveal how the performance of an EHSA can be affected by seals degradations.

Abstract. Volcanic dynamics is driven by the complex interplay between fluid flow (circulation of magmatic and/or hydrothermal fluids) and rock structure (volcano conduits, dykes), the comprehension of which requires both multi-parametric monitoring and modelling of relevant physical and chemical processes of the system. Understanding the factors controlling the dynamics of the processes involved in these interactions is necessary to characterize the overall behaviour of a volcano and the eventual transition mechanisms among stationarity, unrest phases and eruptive styles. The starting point in this context is to have high-quality data of several parameters (seismological, geochemical, geodetic, volcanological), acquired both over years of monitoring activity and focused field experiments. Fundamental contributions come from the use of combined multi-parametric datasets and the adoption of innovative analysis techniques and multi-disciplinary approaches. This Special Issue is addressed to those researchers, who focus their investigations in the field of volcano dynamics. Its main purpose is to shed light on the processes occurring in active volcanic systems over different time scales, with relevant implications for the hazards and the modern monitoring, thus promoting future discussions on this topic. The Issue contains this introducing preface, which describes the Volume aims, and 14 papers, reflecting the main themes. The papers are devoted to the study of some Italian sites, but the proposed approaches are general and therefore applicable to any other volcanic/hydrothermal areas.

Objetivo: Descrever as etapas da adaptação de um protocolo de indicadores para a avaliação da capacidade de gestão da Assistência Farmacêutica a partir das variáveis constantes em um banco de dados nacional. Métodos: Estudo sistemático por meio da convergência de um protocolo de indicadores de avaliação da capacidade de gestão da assistência farmacêutica a nível municipal com dados oriundos da Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos, para elaboração de um protocolo de indicadores de abrangência nacional. Após a adaptação e análise preliminar do protocolo, um estudo de consenso foi realizado em duas etapas: consulta com especialistas e oficina de consenso. Na sequência foi realizado um teste de aplicabilidade do protocolo de indicadores com os dados disponíveis pela pesquisa nacional. Resultados: Entre os indicadores, 17 sofreram alterações e em seis foram alteradas as fontes de coleta de dados. Devido à ausência de informações necessárias para aplicar as medidas preconizadas, 16 indicadores foram excluídos do protocolo original. Ao final, o protocolo proposto foi composto por 30 indicadores organizados em três dimensões: Organizacional, Operacional e Sustentabilidade. Conclusão: Os resultados da validação da aplicabilidade dos indicadores, com base nos dados nacionais, asseguram a sensibilidade do novo protocolo de avaliação no contexto dos serviços farmacêuticos na atenção primária. O novo protocolo permite, assim, avaliar a capacidade de gestão da Assistência Farmacêutica em municípios brasileiros sem prejuízo das premissas que sustentaram o modelo original. O protocolo viabilizará avaliações futuras, sugerindo-se a possível institucionalização destes indicadores para monitoramento contínuo da Assistência Farmacêutica no Brasil. Os resultados deste processo podem ser adotados como ponto de partida para o desenvolvimento de indicadores de capacidade de gestão dos serviços farmacêuticos também em outros países.Palavras-Chave: Avaliação em Saúde, Gestão em Saúde, Assistência Farmacêutica, PNAUM Development of a protocol of indicators for national evaluation of the management capacity of Pharmaceutical Services in Primary Health CareABSTRACTObjective: To describe the stages of adaptation of an indicator protocol for the evaluation of Pharmaceutical Services management capacity from the variables in a national database. Methods: Systematic study through the convergence of a protocol of indicators of evaluation of the management capacity of pharmaceutical services at municipal level with data from the National Survey of Access, Use and Promotion of the Rational Use of Medicines, to elaborate a protocol of indicators. nationwide. After adaptation and preliminary analysis of the protocol, a consensus study was carried out in two steps: consultation with experts and consensus workshop. Subsequently, an applicability test of the indicator protocol was performed with data available from the national survey. Results: Among the indicators, 17 suffered alterations and in six the sources of data collection were altered. Due to the lack of information necessary to implement the recommended measures, 16 indicators were excluded from the original protocol. In the end, the proposed protocol was composed of 30 indicators organized in three dimensions: Organizational, Operational and Sustainability. Conclusions: The results of validating the applicability of the indicators, based on national data, ensure the sensitivity of the new assessment protocol in the context of pharmaceutical services in primary care. Thus, the new protocol allows us to evaluate the Pharmaceutical Services management capacity in Brazilian municipalities, without prejudice to the assumptions that supported the original model. The protocol will enable future evaluations, suggesting the possible institutionalization of these indicators for continuous monitoring of Pharmaceutical Services in Brazil. The results of this process can be taken as a starting point for the development of pharmaceutical services management capacity indicators also in other countries.KEYWORDS: Health Evaluation, Health Management, Pharmaceutical Services, PNAUM

EN 17650 is a proposed new European Standard for the digital preservation of cinematographic works. It allows organizing of content in a systematic way, the so called Cinema Preservation Package (CPP). The standard defines methods to store content in physical and logical structures and describes relationships and metadata for its components. The CPP uses existing XML schemes, in particular METS, EBUCore and PREMIS to store structural, descriptive, technical and provenance metadata. METS XML files with their core metadata contain physical and logical structures of the content, hash values and UUIDs to ensure data integrity and links to external metadata files to enrich the content with additional information. The content itself is stored based on existing public and industry standards, avoiding unnecessary conversion steps. The paper explains the concepts behind the new standard and specifies the usage and combinations of existing schemes with newly introduced metadata parameters.
