A Methodology for Characterizing the Multiscale Pores and Fractures in Anthracite and Semi-Anthracite Coals and Its Application in Analysis of the Storage and Permeable Capacity of Coalbed Methane
Authors: Fang Huihuang , Sang Shuxun , Liu Shiqi
Published: May 2019

Pores and fractures are important components in coal that provide storage space and migration channels for coalbed methane (CBM). To study the importance of pores and fractures to CBM, a combined technique of focused-ion-beam scanning electron microscope (FIB-SEM), X-ray microcomputed tomography (µ-CT), and 3D visualization technology is applied to study the quantitative characterization of multiscale pores and fractures and show their significance for the storage and permeable capacity of CBM. Two high rank coals, anthracite coal (AC) and semi-anthracite coal (SAC), were collected from the southern Qinshui Basin. The results show that two samples show primarily developed organic pores that are filled with minerals. The developmental morphology of the dissolution pores, the shrinkage-induced pores, and the microfractures have important influences on the pore connectivity. The pore connectivity of the SAC sample is poorer than that of the AC sample, and the development of pores and throats is unbalanced. The throats with smaller radii have larger contributions to the volume of the throats. Both samples are beneficial to the adsorption and storage of CBM, but the permeability of the AC sample is better than that of the SAC sample. The porosity of the AC sample is larger than that of the SAC sample, and the microscale pores and nanoscale pores have a larger contribution to the porosity of the SAC and AC samples, respectively. On the basis of the 2D morphology observation, 3D reconstruction analysis, and comparative research of the extracted data, we found that the pore and fracture network of the AC sample contributes more to the storage and permeable capacity of CBM. The introduction and application of the new methodology of the combined technology can enrich the study of multiscale pores and fractures from the nanometer scale to the micron scale and can provide new suggestions for reservoir evaluation in the coal geology sciences.

Current multiplexing strategies for massively parallel sequencing of genomic DNA mainly rely on library indexing in the final steps of library preparation. This procedure is costly and time-consuming because a single library must be produced separately for each sample. Furthermore, library preparation is challenging in the case of low-input fixed samples, such as DNA extracted from formalin-fixed paraffin-embedded (FFPE) tissues. Here, we describe CUTseq, a method that uses restriction enzymes and in vitro transcription to barcode and amplify genomic DNA prior to library construction. We thoroughly validate CUTseq and demonstrate its applicability to both genome and exome sequencing, enabling multi-region genome profiling within single stained FFPE tissue sections, to assess intratumor heterogeneity at high spatial resolution. In conclusion, CUTseq is a versatile and cost-effective method for multiplexed DNA sequencing library preparation that can find numerous applications in research and diagnostics.

Biotoxicity and by-product identification of dye wastewaters
Authors: Chen Jie , Jin Xiaoling , Zhao Chunxia , Qin Zhe , Wang Jingfei , Liang Shu-xuan
Published: May 2019

Dyeing effluent is a typical refractory wastewater containing toxic pollutants. It is difficult to treat it to meet discharge regulations. The biotoxic effects of pollutants on microorganisms are one of the main constraints on efficient wastewater degradation. The aim of this study was to evaluate biotoxic effects and try to screen toxic substances from dye wastewater. The toxic effects of wastewaters collected at different treatment stages from a wastewater treatment plant in a dye industrial park were determined using bioluminescent bacteria (Vibrio qinghaiensis sp.-Q67). Toxic substances from both influent and effluents were identified by gas chromatography-mass spectrometry. Spearman's rank correlation coefficients indicated significant positive correlations between the toxicity values, and chemical oxygen demand (COD), NH3-N, and total nitrogen (TN). After identifying the toxic levels, phenol, pyridine, and esters were confirmed as the principal organic pollutants in dye wastewater, and increase its toxicity.

Published: May 2019

1,5-Benzodiazepines are considered some of the most vital classes of heterocyclic compounds due to their amazing biological and varied pharmacological activities. They are regarded as privileged structures and therefore have been striking synthetic targets for organic and medicinal chemists over the last decade. This results in the exploration of various silica supported catalysts, Lewis acids, organoacids, magnetic nanoparticles and other miscellaneous catalysts that have been investigated till date for an efficient and green synthesis of 1,5-benzodiazepine and its derivatives. The current review article primarily covers the one-pot green chemical synthesis of 1,5- benzodiazepines using various novel catalysts. The main motive of this review is the assessment of the literature on various catalysts along with their yield, reaction condition, and mechanism of action. In the end, the entire catalysts are structured systematically into various Lewis acids, Bronsted organoacids, supported catalysts, nanocatalysts, and miscellaneous catalysts and are presented in the form of tables for quick ‘at a glance’ study of catalysts, their reaction condition, time taken, etc.

LVAD patients with bioprosthetic aortic valve are more prone to leaflet fusion resulting in valvular stenosis and regurgitation. We present a 46 year old patient who had LV systolic function recovery while on LVAD. However, he had a severely stenotic aortic valve bioprosthesis with leaflet fusion that had to be corrected before deactivating his LVAD. Due to high surgical risk, we performed valve-in-valve TAVR with an Evolut CoreValve , however, the patient had significant aortic regurgitation secondary to deployment above the bioprosthetic valve ring. We successfully deployed a second Evolut CoreValve inside the ring with excellent results. This was followed by a successful LVAD deactivation next day. His LV systolic function continued to recover and he had no heart failure symptoms at 3 month follow up. In the right settings, TAVR in recovered LVAD patients with aortic stenosis as bridge to LVAD deactivation is viable option, especially for patients who fall in the high risk group. To the best of our knowledge, this is the first reported case of a valve-in-valve TAVR followed by successful LVAD deactivation in the setting of recovered LV systolic function.

ERROR OF MODELING ECHO SIGNALS FROM EARTH SURFACE ARISING DUE TO DISCRETE ASSIGNMENT OF REFLECTIVE PROPERTIES
Authors: Oreshkina M. V.
Published: May 2019

The use of discrete distribution of the earth surface reflective properties to simulate echoes leads inevitably to the errors in setting the parameters of the simulated signal. Therefore, there is a problem of choosing the optimal ratio between the intensity of the errors and the sampling frequency, which affects the speed of subsequent echo calculations based on a discrete surface model. To solve this problem, relations linking the statistical characteristics of the errors in specifying the power of echoes with the sample interval of the surface map are obtained. Two approaches are used. In the first case, dependences between the errors of setting the mean value and the variance of the normalized radar cross section and the sample interval are obtained. In the second case, the averaged error values are obtained after interpolating the sampled values. The paper also presents general relations for calculating the error value for the 0–2π angle sector based on the ratios for the sampling interval.
SIMULATION OF REFLECTIONS FROM SURFACE-DISTRIBUTED OBJECTS ON EXAMPLE OF FRAGMENT OF UNDERLYING SURFACE
Authors: Stepanov M. A.
Published: May 2019

The paper considers the problem of the synthesis of a low-point model of the relief of the underlying surface. The model can be used to conduct semi-null simulation when the radar is operating in low-altitude flight mode. A method for defining a relief in the form of a piecewise broken approximation is proposed. An algorithm is presented that allows real-time, for a given relief, to calculate for each of the elements of the resolution in range its angular position and angular dimensions. These parameters determine the expectation of the angular noise and the width of their probability density, respectively. The ability to work in real time is provided using a straight line in a spherical coordinate system when defining the relief. The recommendations on the choice of a geometric model from the previously justified family are given. The synthesized models provide a given form of the correlation functions of angular noise and adequately replace reflections from distributed objects. Geometric models can be used as the basis for matrix simulators of reflected electromagnetic waves.
Promoting Small Business Support of Youth Physical Activity in Low-Income, Minority Neighborhoods: Protocol for a Randomized Controlled Trial
Authors: Suminski Jr Richard Robert , Robson Shannon , Turner Jennie , Plautz Eric
Published: May 2019

Background

An unacceptably high percentage of our nation’s low-income, minority youth (age<18 years) are not regularly physically active. One reason for this could be their lack of access to quality youth physical activity opportunities (YPAOs). Our previous research found that small businesses (<500 employees), which represent over 99.64% (27.9/28.0 million businesses in United States) of all employers, are powerful resources for creating and improving YPAOs. In accordance with the socioecological model and established philanthropic principles, we developed an alpha version of an intervention (alpha-i) for increasing small businesses’ involvement with YPAOs.

Objective

The aims of this proposed study are to (1) create a beta version (beta-i) of the intervention and (2) conduct a pilot study of its impact on small business support for YPAOs and YPAO utilization by the youth in low-income, minority neighborhoods.

Methods

The alpha-i will be refined using information from focus groups and surveys conducted with small business owners and managers, YPAO providers, and parents and guardians of the youths from low-income, predominantly minority neighborhoods. A cluster randomized controlled trial will then be conducted for 1 year to examine the effects of the refined intervention (beta-i) on small business support for YPAOs in 10 low-income, minority neighborhoods. The control group of neighborhoods (n=10) will be provided with a standard practice intervention. The primary outcome for aim 2 will be the percentage of small businesses not supporting YPAOs at baseline that subsequently provide support for YPAOs at follow-up. We also will consider the US dollar equivalent of all types of support (monetary, goods/services, and time) donated for YPAOs by small businesses. In addition, we will examine the impact of the increased small business support for YPAOs on YPAO utilization by the youth.

Results

As of May 1, 2019, all YPAOs and small businesses in the study neighborhoods have been identified, and surveys have begun with these groups. In addition, 9 focus groups were completed, and the data have been transcribed. We anticipate that manuscripts regarding these aspects of the study will be submitted in fall 2019.

Conclusions

The proposed study is significant because it will provide evidence that an easily replicated approach can be used to increase small business support for YPAOs and that this support results in greater use of the YPAOs by youth. A logical next step will be to determine if YPAO changes resulting from increased small business support positively influence youth physical activity levels.

Sources of Health Information and Their Impacts on Medical Knowledge Perception Among the Saudi Arabian Population: Cross-Sectional Study (Preprint)
Authors: Alduraywish Shatha A , Altamimi Lamees A , Aldhuwayhi Rawan A , AlZamil Lama R , Alzeghayer Luluh Y , Alsaleh Futoon S , Aldakheel Fahad M , Tharkar Shabana
Published: May 2019

BACKGROUND

Having a reliable source for health information is vital to build a strong foundation of knowledge, especially with the current revolution of the internet and social media, which raises many concerns regarding harmful effects on the health of the public. However, there are no studies on how the Saudi Arabian population seeks health information. Details about the most used and trusted sources of health information among the public will help health authorities and public awareness accounts on social media to effectively disseminate health information.

OBJECTIVE

To investigate the types of sources accessed by the Saudi Arabian population while seeking health information, as well as their level of trust in the sources and to assess the impact of these sources on their perception of medical knowledge and health decision-making.

METHODS

A cross-sectional study was conducted to meet the objectives. The study population included both men and women who were aged 16 years or more and visited primary care clinics at King Khalid University Hospital. Four hundred and thirteen participants were sampled using the simple random method, and a self-administered questionnaire was used to collect data. The data were analyzed using SPSS software (IBM Corp, Armonk, New York, USA).

RESULTS

A total of 413 participants were included in this study, and of these, 99 (24.0%) were males and 206 (49.9%) had a bachelor’s degree. Doctors were chosen as the first source of information by 87.6% (283/323) of the participants, and they were completely trusted by most of the population (326/411, 79.3%). The second most commonly used source was pharmacists (112/194, 57.7%), and they were partially trusted by 41.4% (159/384) of the participants. Internet searches, social media, and traditional medicine were not prioritized by most of the participants as the first or second source of health information. The majority of the participants did not trust information obtained from social media, and WhatsApp was the most untrusted source. Almost half of the respondents (197/413, 47.7%) acknowledged that various sources of information can often help them understand their health problems. However, the majority disagreed on substituting a doctor’s prescription with information obtained from the internet or a friend or relative.

CONCLUSIONS

Although physicians were preferred and highly trusted, internet sources appeared to impact the medical knowledge of the population. The population still preferred to use internet search to obtain health information prior to a doctor’s visit.

Published: May 2019

BACKGROUND

Optimizing the use of social media to promote hospital branding is important in the present digital era. In Taiwan, only 51.1% of hospitals have official Facebook fan pages. The numbers of likes for these hospitals are also relatively low.

OBJECTIVE

Our objective was to establish a special branding team for social media operation, led by top administrators of our hospital. Here we present our strategic imperative for promoting hospital branding as well as an analysis of its effectiveness.

METHODS

Led by top administrators, the branding team was formed by 11 divisions to create branding strategies. From 2016 to 2018, the team implemented action plans. All information unique to the hospital was posted on Facebook, as well as on the hospital’s official website. To determine the plans’ efficiencies, we obtained reference data from Google Analytics, and we compared Facebook Insights reports for 2016 with those for 2017 and 2018.

RESULTS

One of the branding team’s main missions was to establish branding strategies and to integrate segmental branding messages. In each quarter we regularly monitored a total of 52 action plan indicators, including those for process and outcome, and discussed the results at team meetings. We selected 4 main performance outcome indicators to reflect the effectiveness of the branding efforts. Compared with 2016, the numbers of likes posted on the Facebook fan page increased by 61.2% in 2017 and 116.2% in 2018. Similarly, visits to the hospital website increased by 4.8% in 2017 and 33.1% in 2018. Most Facebook fan page and website viewers were in 2 age groups: 25 to 34 years, and 35 to 44 years. Women constituted 60.42% (14,160/23,436) of Facebook fans and 59.39% (778,992/1,311,605) of website viewers. According to the Facebook Insights reports, the number of likes and post sharing both increased in 2017 and 2018, relative to 2016. Comment messages also increased from 2016 to 2018 (P=.02 for the trend). The most common theme of posts varied over time, from media reports in 2016, to innovative services in both 2017 and 2018. Likes for innovative services posts increased from 2016 through 2018 (P=.045 for the trend). By the end of 2018, we recorded 23,436 cumulative likes for posts, the highest number among medical centers in Taiwan.

CONCLUSIONS

We achieved the largest number of Facebook fans among all medical centers in Taiwan. We would like to share our experience with other hospitals that might be interested in engaging in social media for future communications and interactions with their patients.
Prevention of HIV and Other Sexually Transmitted Infections by Geofencing and Contextualized Messages With a Gamified App, UBESAFE: Design and Creation Study (Preprint)
Authors: Besoain Felipe , Perez-Navarro Antoni , Jacques Aviñó Constanza , Caylà Joan A , Barriga Nicolas A , Garcia de Olalla Patricia
Published: May 2019

BACKGROUND

Advances in the development of information and communication technologies have facilitated social and sexual interrelationships, thanks to the websites and apps created to this end. However, these resources can also encourage sexual contacts without appropriate preventive measures in relation to HIV and other sexually transmitted infections (STIs). How can users be helped to benefit from the advantages of these apps while keeping in mind those preventive measures?

OBJECTIVE

This study aimed to prevent STIs by helping users to remember preventive measures in the risky situations.

METHODS

We have used the design and creation methodology and have developed a software system. This system has two parts: an Android operating system app with emphasis on ubiquitous computing and gamification as well as a server with a webpage. First, a functional test with 5 men who have sex with men (MSM) allowed us to test the app with end users. In addition, a feasibility test with 4 MSM for a month allowed us to try the UBESAFE system with all its functionalities.

RESULTS

The main output is a system called UBESAFE that is addressed to MSM. The system has two main parts: (1) an app that sends preventive contextualized messages to users when they use a contact app or when they are near a point where sexual contacts are likely and (2) a server part that was managed by the public health agency of Barcelona (ASPB), which preserves the quality and pertinence of messages and places and offers instant help to users. To increase users’ adherence, UBESAFE uses a gamified system to engage users in the creation of preventive messages. Users increased the initial pool of messages by more than 100% (34/30) and created more than 56% (9/16) of places (named hot zones).

CONCLUSIONS

The system helped MSM who used it to become conscious about HIV and other STIs. The system also helped the ASPB to stay in contact with MSM and to detect behaviors that could benefit from preventive measures. All functions were performed in a nonintrusive manner because users used the app privately. Furthermore, the system has shown how important it is to make users a part of the creation process as well as to develop apps that work by themselves and thus become useful to the users.

Published: May 2019

BACKGROUND

Virtual patients are interactive digital simulations of clinical scenarios for the purpose of health professions education. There is no current collated evidence on the effectiveness of this form of education.

OBJECTIVE

The goal of this study was to evaluate the effectiveness of virtual patients compared with traditional education, blended with traditional education, compared with other types of digital education, and design variants of virtual patients in health professions education. The outcomes of interest were knowledge, skills, attitudes, and satisfaction.

METHODS

We performed a systematic review on the effectiveness of virtual patient simulations in pre- and postregistration health professions education following Cochrane methodology. We searched 7 databases from the year 1990 up to September 2018. No language restrictions were applied. We included randomized controlled trials and cluster randomized trials. We independently selected studies, extracted data, and assessed risk of bias and then compared the information in pairs. We contacted study authors for additional information if necessary. All pooled analyses were based on random-effects models.

RESULTS

A total of 51 trials involving 4696 participants met our inclusion criteria. Furthermore, 25 studies compared virtual patients with traditional education, 11 studies investigated virtual patients as blended learning, 5 studies compared virtual patients with different forms of digital education, and 10 studies compared different design variants. The pooled analysis of studies comparing the effect of virtual patients to traditional education showed similar results for knowledge (standardized mean difference [SMD]=0.11, 95% CI −0.17 to 0.39, I2=74%, n=927) and favored virtual patients for skills (SMD=0.90, 95% CI 0.49 to 1.32, I2=88%, n=897). Studies measuring attitudes and satisfaction predominantly used surveys with item-by-item comparison. Trials comparing virtual patients with different forms of digital education and design variants were not numerous enough to give clear recommendations. Several methodological limitations in the included studies and heterogeneity contributed to a generally low quality of evidence.

CONCLUSIONS

Low to modest and mixed evidence suggests that when compared with traditional education, virtual patients can more effectively improve skills, and at least as effectively improve knowledge. The skills that improved were clinical reasoning, procedural skills, and a mix of procedural and team skills. We found evidence of effectiveness in both high-income and low- and middle-income countries, demonstrating the global applicability of virtual patients. Further research should explore the utility of different design variants of virtual patients.

El bagre marino Bagre panamensis es un recurso pesquero que se explota a lo largo de todo el año y sin restricción alguna en el sureste del Golfo de California. Para manejar de manera adecuada la pesquería comercial de algún recurso, es importante conocer aspectos de su biología básica como la reproducción. En el presente estudio se estimó el periodo de reproducción a través de los índices gonadosomático (IGS), hepatosomático (IHS) y el factor de condición de B. panamensis. Las muestras fueron obtenidas mensualmente entre noviembre de 2015 y octubre de 2016 de la pesca comercial del área de San Blas. Se recolectaron 346 ejemplares de los cuales 182 fueron hembras y 164 machos. Las tallas (longitud total y peso) encontradas no mostraron diferencias entre sexos. La proporción sexual no fue diferente de 1:1 para el total de las muestras. La relación peso-longitud mostró que ambos sexos presentaron un tipo de crecimiento alométrico positivo. De acuerdo al índice gonadosomático (IGS) y el hepatosomático (IHS) se observó que esta especie presenta un periodo de reproducción al año, que va de mayo a agosto. Con base en estos resultados, se podría proponer una estrategia de manejo para esta pesquería en el sureste del Golfo de California.
Spatial changes in the infaunal community of a macrotidal flat in Bahía San Julián, Southern Patagonia, Argentina
Authors: Martin Juan P. , Sar Alicia , Caminos Carlos
Published: May 2019

The soft-bottom macrobenthos of Bahía San Julián intertidal was surveyed to identify infaunal assemblages and analyze their relationships with the main environmental factors determining species distribution. Four seasonal surveys (summer, autumn, winter and spring) were performed in the middle and lower intertidal levels at seven sampling stations established on both sides of an urban sewage discharge point, and water and sediment variables were measured. To explore possible spatial variations in the community, environmental and biological data were analyzed using univariate and multivariate statistics. Community composition varied with intertidal level, sediment characteristics and distance to sewage discharge site. In sediment with high mud content, the community was characterized by Darina solenoides, Mysella patagona, Eteone sculpta, Scolecolepides uncinatus and Capitella sp., in the middle intertidal, and was characterized by M. patagona and Ampelisca sp. in the lower intertidal. In sediment with dominance of fine sand, the community was characterized by Aricidea sp. at both intertidal levels. Near the effluent discharge site, the community was largely dominated by M. patagona. Intertidal level and sediment particle size are the main factors determining the composition of benthic assemblages in the study area. Sewage discharge also affects the composition of the infaunal community, possibly as a result of the contribution of particulate organic matter in suspension that stimulates the populations of detritus feeders.
Effect of nitrate and irradiance on fatty acid production in microalgae cultivated for feeding larvae and broodstock conditioning in batch culture

Published: May 2019

The aim of this study was to compare conditions for the production of high levels of PUFA, EPA and DHA in cultured microalgae for larval bivalve feeding stages. It assessed fatty acid composition by gas chromatography for Isochrysis galbana Parke (T-Iso) and 2 species of Chaetoceros, C. gracilis Pantocsek and C. constrictus Gran. Species were studied in batch cultures, at the beginning of stationary growth phase with different irradiance and 2 levels of nitrogen content for Chaetoceros sp., and constant irradiance with 5 concentrations of sodium nitrate for I. galbana in an F/2 medium. Isochrysis galbana produced higher levels of linolenic acid and docosahexaenoic acid than eicosapentaenoic acid (EPA) at low N-nitrate concentrations; however, fatty acids increased notably with surplus N-nitrate, above F/2 medium content. Low irradiance and normal concentration of nitrates in the batches of Chaetoceros gracilis species produced a greater EPA content. C. constrictus, a diatom isolated from phytoplankton samples, presented higher levels of EPA and DHA at low levels of nitrogen and low irradiance.

Este trabalho identifica algumas contribuições teóricas do pensamento latino-americano “forte” para compreender o Estado capitalista, bem como os elementos que podem contribuir para a compreensão das transformações do Estado durante a globalização neoliberal. Para tanto, recorremos a aspectos da Teoria da Dependência que abordaram as especificidades do Estado e do capitalismo na região, bem como as contribuições de pensadores como Kaplan e Zavaleta sobre os debates de Nikos Poulantzas sobre o Estado capitalista. Por fim, destacam-se críticas a essa corrente de pensamento por parte dos estudiosos do Estado e do Capitalismo Global, considerando que, embora seja necessário repensar a rigidez de categorias como o Norte e o Sul, o legado do pensamento latino-americano “forte” continua a representar uma contribuição vigorosa para entender as transformações do Estado capitalista na América Latina durante a globalização.

Este artigo apresenta e analisa os fatores que condicionam a configuração dos elementos da estratégia de manufatura em grandes e pequenas empresas fabricantes de calçados da cidade de Franca-SP. A motivação desta pesquisa é verificar quais são os fatores que influenciam o processo decisório dos gerentes na ocasião de elaboração desta estratégia. A principal conclusão é que a autonomia dos gerentes é relativa; na prática, o processo de elaboração da estratégia de manufatura é limitado por fatores que fogem ao escopo decisório dos gerentes. Isso faz com que a estratégia de manufatura seja o resultado de um processo decisório adaptado às restrições da empresa.
Implementation of Double-Timing Pulse Interpolation Applied to Compact Piston Provers

Published: May 2019

This work presents an electronic circuit for double-timing pulse interpolation applied to compact piston provers (also referred as small volume provers). Compact provers are usually employed to prove meters with pulsed outputs. API and ISO standards [1,2] recommend a minimum of 10.000 pulses per run to obtain a resolution better than ± 0.01%. Since the volume of fluid displaced by a compact prover is relatively small, the number of pulses produced during a proving run is often considerably less than 10.000 pulses. Pulse interpolation techniques are commonly used to increase resolution and to diminish uncertainty during a proving run by estimating the fractional part of meter pulses within the time interval of the calibration. In this way, pulse interpolation techniques are essential to obtain accurate flow measurements and to allow the calibration of meters with compact provers.

Our implementation uses a compact piston prover with an internal volume of 12 L and maximum flow capacity of 180 L/min. In order to implement the double-timing pulse interpolation method, we have used a Pentium D, 2.80 GHz installed with a 16-bit counter/timer board. Data acquisition and control software were written using VB .Net. An electronic circuitry was built to activate/deactivate counters gates, and to collect pulses. Some requirements and limitations of pulse interpolation techniques such as circuitry testing and pulse stability are also discussed in this work.

Authors: Carmo Luiz Fernando Rust da Costa , Machado Raphael Carlos Santos
Published: May 2019

Este artigo descreve uma metodologia de verificação da integridade de software apoiada na medição de “efeitos colaterais”, eventos físicos associados ao processamento de dados. Mostramos que a “metrologia de efeitos colaterais” aumenta a confiança no processo de verificação de integridade. Apresentamos duas abordagens para uso de metrologia temporal em verificação de integridade. A primeira abordagem permite a avaliação do comportamento temporal de um software sem que seja necessário interromper o funcionamento do equipamento onde o software em verificação está embarcado. Na segunda abordagem, o funcionamento do equipamento deve ser interrompido e os módulos que armazenam o software em verificação devem ser removidos, de forma a obter maior certeza acerca dos resultados obtidos.

Esse artigo apresenta a utilização do Método de Análise Hierárquica (AHP) com objetivo de auxiliar a tomada de decisão na escolha do software estatístico mais adequado a demanda de uma universidade pública. O AHP é uma metodologia multicritério para a tomada de decisão cuja utilização é extremamente divulgada e se baseia na capacidade do ser humano em construir e entender hierarquias. O desenvolvimento do modelo teve como base a necessidade do Instituto de Matemática e Estatística (IME) da Universidade do Estado do Rio de Janeiro (UERJ) para compra e utilização de um software estatístico com a finalidade de uso dos alunos e professores dos cursos desse mesmo Instituto. Nesse contexto, são apresentados o AHP e suas principais características, abordardas a importância dos softwares estatísticos como ferramenta de integração do aluno com métodos estatísticos computacionais e a importância desse instrumento de ensino que possibilita a capacitação em técnicas estatísticas utilizadas amplamente no mercado de trabalho.

A survey of 40 students was conducted; the data is presented and discussed.
A FORMAÇÃO DOS OPERADORES DE PROCESSOS CONTÍNUOS EM CONTEXTOS DE CONSTRANGIMENTO DA APRENDIZAGEM
Authors: Bouyer Gilbert Cardoso
Published: May 2019

O termo desenvolvimento cognitivo é freqüentemente usado em pesquisas ergonômicas. Entretanto, os constrangimentos (“contraintes”) da aprendizagem raramente são mencionados. Usando o método da Análise Ergonômica do Trabalho (AET), demonstramos como os operadores aprendem a atividade de controle de processo contínuo, em um contexto de constrangimentos, e demonstramos que a complexidade e os constrangimentos do trabalho influenciam o tempo para o desenvolvimento cognitivo. Apresentamos também aspectos que classificam este tipo de aprendizagem como complexa. Um total de 18 operadores foram entrevistados e observados. Os principais constrangimentos no desenvolvimento dos operadores são: a organização do trabalho e a hierarquia das indústrias de processo contínuo (IPC’s). O tempo é um constrangimento porque os operadores têm que aprender o controle de processo em um contexto de tempo curto, com grandes exigências dos gerentes. A aprendizagem das situações reais é urgente, e os operadores têm que lidar com elas rapidamente.

Published: May 2019

Sistemas de informação podem apresentar falhas que representam impactos de diferente severidade para as empresas.

Os modelos de análise de confi abilidade usualmente baseiam-se na ocorrência de falhas através da análise de tempos

até falha; tais modelos, porém, não contemplam a severidade dos impactos causados pelas falhas. Neste artigo propõese

um modelo de análise de confi abilidade de sistemas de informação baseado na análise de confi abilidade de sistemas

multi-estados k-em-n. O modelo contempla a severidade dos impactos causados pelas falhas, além prover uma melhor

representação da realidade operacional de sistemas de informação. Um estudo de caso ilustra os desenvolvimentos

propostos no artigo.

O processo de desenvolvimento de produtos (PDP) é um diferencial para manter as empresas competitivas. Na indústria de confecção, o desenvolvimento de produto é dinâmico e sofre grande influência das variações do mercado. Neste contexto, para a estruturação do PDP se faz necessária a utilização de modelos que estabeleçam etapas sistematizadas para o processo. O presente trabalho tem como objetivo apresentar um caso de utilização de um modelo para fins de diagnóstico do processo de desenvolvimento de produto em uma indústria têxtil de confecção de vestuário. Para isso, é realizada uma análise do PDP na empresa estudada, tomando como base o modelo de referência de Rozenfeld et al., (2006). O método principal é o estudo de caso, e os instrumentos de coleta são entrevistas e visitas técnicas a empresa. Como resultado, tem-se uma análise do PDP da empresa e posterior verificação do nível de maturidade do processo de desenvolvimento de produto. A utilização do modelo de referência demonstrou ser eficiente, sendo um bom padrão para avaliação do nível de evolução da empresa em desenvolvimento de produtos. Foi possível concluir que a empresa estudada apresenta um nível de maturidade básico para o desenvolvimento de produtos, revelando haver a necessidade de se intensificarem os estudos para estruturação do PDP da mesma, vislumbrando, ainda, uma conseqüente otimização.
