Background
Although the relationship between allergic sensitization and increased respiratory symptoms of chronic obstructive pulmonary disease (COPD) has been suggested, which allergen has a significant effect on COPD pathology is unclear. This study aimed to identify the specific IgE related to clinical features of COPD and the diagnosis of asthma-COPD overlap (ACO).
Methods
We recruited 70 patients with COPD and analyzed 39 IgE using panel IgE test (View Allergy 39®). ACO was diagnosed according to the Japanese Respiratory Society Guidelines.
Results
As for perennial aeroallergens, the positivity for moth (35.4%), cockroach (23.1%), Dermatophagoides pteronyssinus (21.5%), house dust (21.5%), and Candida (21.5%) and, concerning pollen, Japanese cedar (36.9%) and Japanese cypress (23.1%) exceeded 20%. Only the positivity of IgE for Dermatophagoides pteronyssinus and house dust was significantly higher in ACO compared with that in non-ACO COPD. Moreover, it contributed to the diagnosis of ACO in an IgE class-dependent manner. Patients with cockroach IgE exhibited higher residual volume, whereas those with Japanese cedar IgE exhibited better diffusion capacity than negative patients. The contribution for ACO diagnosis by the receiver operating characteristic curve analysis was comparable among total IgE (cutoff value: 158 IU/mL), blood eosinophil count (234/µl), and fraction of exhaled nitric oxide (31.0 ppb).
Conclusions
The prominent role of mite-specific IgE in the diagnosis and pathology of ACO and the potentially detrimental effect of cockroach sensitization on air trapping in COPD were suggested. The finding highlights the future development of a treatment targeting IgE as a treatable trait in COPD.

BackgroundMajor cost of bioethanol is attributed to enzymes employed in biomass hydrolysis. Lignocellulolytic enzymes are predominantly produced from the hyper cellulolytic mutant filamentous fungus Trichoderma reesei RUT-C30. Several decades of research have failed to provide an industrial grade organism producing higher titers of an effective synergistic biomass hydrolyzing enzyme cocktail. Penicillium janthinellum NCIM1366 was reported as a cellulase hyper producer and a potential alternative to T. reesei, but a comparison of their hydrolytic performance was seldom attempted. ResultsHydrolysis of acid or alkali pretreated rice straw using cellulase enzyme preparations from P. janthinellum and T. reesei indicated 37 and 43 % higher glucose release respectively with P. janthinellum enzymes. A comparison of these fungi with respect to their secreted enzymes indicated that the crude enzyme preparation from P. janthinellum showed 28 % higher overall cellulase activity. It also had an exceptional 10-fold higher beta-glucosidase activity compared to that of T. reesei, leading to a lower cellobiose accumulation and thus alleviating the feedback inhibition. P. janthinellum secreted more number of proteins to the extracellular medium whose total concentration was 1.8 fold higher than T. reesei. Secretome analyses of the two fungi revealed more number of CAZymes and a higher relative abundance of cellulases upon cellulose induction in the fungus.ConclusionsThe results revealed the ability P. janthinellum for efficient biomass degradation through hyper cellulase production, and it outperformed the established industrial cellulase producer T. reesei in the hydrolysis experiments. A higher level of induction, larger number of secreted CAZymes and a high relative proportion of BGL to cellulases could be the possible reasons for its performance advantage in biomass hydrolysis.

Background: Systemic lupus erythematosus (SLE) is the prototype autoimmune disease with high inflammatory cytokine levels. In autoimmune conditions, diet could modify the inflammatory status, comorbidities and pharmacotherapy administered in SLE patients. The aim of this study was to assess the relationship of the inflammatory diet status and dietary intake with comorbidities and pharmacotherapy administered in SLE patients. Methods: A cross-sectional study was conducted in sixty-eight Mexican-Mestizo female SLE patients. Dietary intake was estimated from three 24h food records by Nutritionist Pro-Diet software and 27 food parameters were used to evaluate the inflammatory diet status by the normal dietary inflammatory index (DII®). Results: SLE patients presented a global pro-inflammatory diet status (DII: 0.71 ± 1.78). Chloroquine (CQ) administration was related to a pro-inflammatory diet status compared to hydroxychloroquine (HCQ) administration, which was related to an anti-inflammatory diet status (CQ= DII score: 1.385±1.327 vs. HCQ= DII score: 0.004±2.024; p=0.002). CQ administration conferred a pro-inflammatory DII score (β coefficient= 1.20; CI: 1–2.02; R2=0.11; p<0.01) and lower total-cholesterol (β coefficient=-29.2; CI: -4.03 to -54.5; R2=0.07; p<0.05); conversely, HCQ administration conferred an anti-inflammatory DII score (β coefficient= -1.29; CI: -0.46 to -2.12; R2=0.13; p<0.01). SLE patients with CQ administration had lower intake of energy and 12 nutrients evaluated (CQ vs. HCQ; p <0.05), and SLE patients with HCQ treatment had a better achievement ≥100% of daily dietary reference intake (DRI) of energy (HCQ 77% vs. CQ 52%; p=0.03), vitamin A (HCQ 65% vs. CQ 29%; p<0.01), cholesterol (HCQ 29% vs. CQ 3%; p<0.01), and fiber (HCQ 26% vs. CQ 6%; p=0.03).Conclusions: In SLE patients the CQ administration was related to a pro-inflammatory diet status and low total-cholesterol, and HCQ administration with an anti-inflammatory diet status and better dietary intake.

Reproductive fluids have been recently proposed as the most adequate natural additive to complement the chemically defined in vitro culture media in different animal models, since they contain the full range of molecules necessary for the fertilization and development of preimplantation embryos. However, reproductive fluids potentially are problematic in terms of biosecurity and reproducibility of results, and their availability is scarce. Therefore, we have optimized the protocols to characterize the physico-chemical and functional properties of human reproductive fluids to establish the security ranges that could allow their use as natural additives and using the least possible volume of fluids collected. The results of this study offer, for the first time, a complete quality control guideline for human reproductive fluids, including the security levels (referred from physiological values) that should be taken into account for further use – i.e., osmolality, pH, total protein concentrations, presence of endotoxins and sterility conditions. In addition, a functional test has been developed evaluating the in vitro growth of bovine embryos in medium with human reproductive fluids. Finally, as a proof of concept, four embryos cultured with uterine fluid of their own mothers were transferred and two resulted in successful pregnancy and delivery of healthy babies. In conclusion, this study paves the way towards the future use of more natural culture media in human ART.
Conjunctive Use of BTC and Batch Methods for Heavy Metal Transport
Authors: Hussein Mohamed Fahmy , Khater Hassan
Published: August 2020

Marginal sediments can be used to combat punctual pollution by heavy metals in industrial zones. Such practice requires information on metal-concentration in the workshop discharge water. Knowledge about the reaction of the heavy metal with the sediment available in the landscape is of utmost importance. Modeling of batch experiments and breakthrough curves, BTC, supplies relevant information in this regard. We modeled the static batch-data by Freundlich isotherms for testing CdCl2 aqueous solutions equilibria with sandy loam sediment and the dynamic column-data by two codes, CfitM and CfitIM, under saturated water flow conditions. Three Cd-concentrations (5, 20, and 40 ppm) were employed to investigate the conjunction of using two procedures for obtaining the pertinent parameters for the transport of such a heavy metal and the design of the adequate Cd-trap. The results showed the deviations of the two techniques due to differences in their theoretical concepts, mathematical formulation, and performance. The batch method showed utility in supplying first guesses for the retardation factor, R, to insert into the 4-parameter analytical code, CfitIM, applied for column BTC modeling. The iteratively-obtained-parameters of the Freundlich equation were then employed to generate the distribution coefficient, k d. The generated value was, in turn, used to get more fair guess for the retardation factor, R, to use as a fixed-value in the CfitIM code to get an in-depth insight into the BTC dynamics and to obtain the other pertinent model parameters. The BTC runs indicated that the concentration controls the distinctive adsorption and transport rate and behavior of the heavy metal in the sediment column. The most dilute solution offered the highest Cd impediment, as shown by the most significant values for the distribution coefficient, k d, and retardation factor, R. The malfunction of the sediment as a trap appeared at Cd-concentrations four to eight folds higher than the most dilute solution. However, the loamy sand trap is successful when fed with a dilute aqueous solution. A set of successive traps is to arrange in tandem lines when moderate to high concentration is to discharge from an industrial workshop. The results emphasize the utility of the mutual use of these two lab procedures for the design of adequate traps and landfills and the simulation of more complex situations in the field. The point-pollution control needs to continue running batch and BTC experiments and to carry out their corresponding modeling.

Background: Gastrointestinal manifestations and gut dysbiosis are prevalent after SARS-CoV2 infection.With the continuously increasing number of infected cases, more attention should be paid to this particular population in post-infection recovery.cWe aimed to investigate the potential beneficial effect of FMT on gastrointestinal symptoms, gut dysbiosis and immune status in discharged COVID-19 patients. Results: Gastrointestinal and psychological disorder (45.5%) were observed in COVID-19 patients during post-infection recovery, improvement of which were observed after FMT. Most of the lab results including blood routine and blood biochemistry, within the normal range. The general distribution of 69 different types of lymphocytes differed between before and after FMT. FMT exert significant effect on B cells which was characterized as decreased naive B cell ( P =0.012) and increased memory B cells ( P = 0.001) and non-switched B cells ( P = 0.012).The microbial community richness indicated by OTUs number, observed species and Chao1 estimators was marginally increased after FMT, whereas the community diversity estimated by the Shannon and Simpson index showed no significant changes after FMT. Gut microbiome composition of discharged COVID-19 patients differed from that of the general population at both phylum and genera level, which was characterized with a lower proportion of Firmicutes (41.0%) and Actinobacteria (4.0%), higher proportion of Bacteroidetes (42.9%) and Proteobacteriato (9.2%). FMT can partially restore the gutdysbiosis by increasing the relative abundance of Actinobacteria (15.0%) and reducing Proteobacteriato (2.8%) at the phylum level. At the genera level, Bifidobacterium and Faecalibacterium , which were dominant genera in the human gut microbiota and were beneficial for human health, had significantly increased after FMT. Conclusions: Gastrointestinal and gut dysbiosis were observed in COVID-19 patients during post-infection recovery. FMT can improve the immune functionality, restore the gut microbiota, alleviate gastrointestinal disorders, and may serve as a potential therapeutic and rehabilitative intervention for the COVID-19.

Background Epidemiological changes led to review health services organization and nursing education, in order to train practitioners capable of effectively dealing with new healthcare needs. Master of Science in Nursing (MSN) degree is a post-graduation training curriculum aimed at providing nurses a method to approach complex and unconventional problems. This survey aims to assess if the skills acquired through MSN degree were implemented in the workplace and were useful for professional advancements. Methods This survey involved 257 MSN graduates of Polytechnic University of Marche, 196 of them completed the survey (response rate 76.3%). Logistic regression models were developed to test independent correlation between variables. Results A positive relation between acquisition of skills and their implementation in the workplace has been demonstrated in all training areas: clinical (OR=25.2; p<0.001), management (OR=7.4; p<0.001), educational (OR=14.2; p<0.001), research (OR=18.8; p<0.001). Only implementation of management skills resulted associated to hierarchical position (nurse managers: OR=11.8; p=0.006; service director nurses: OR=14.6; p=0.025) and age class (≥50 years old: OR=7.3; p=0.004). Economical progressions resulted to be only related to formal hierarchical advancements (OR=27.9; p<0.001), but acquisition of skills allows MSN graduated to increase collaboration in research or educative projects (OR=3.3; p=0.010) and publication of scientific papers (OR=8.7; p<0.001). Conclusions Although application of managerial skills requires the achievement of a higher hierarchical position, implementation of these skills can be realized by all MSN graduates, regardless of their age and hierarchical position. This contribute to improve areas of research and develop new models of nursing care necessary to manage chronic and complex patients.

Background
Scarring alopecia in systemic lupus erythematosus (SLE) patients caused reduced life quality and prolonged disease course. This case control study aims to survey the prevalence of scarring alopecia during the disease course of SLE and evaluate the risk factors for scarring alopecia.
Methods
SLE patients in Chinese SLE treatment and Research group (CSTAR) were recruited. Scarring alopecia was defined according to the SLICC/ACR-DI which was collected during follow-up visit or via self-reported questionnaires. We collected demographic characteristics, common comorbidities, autoantibody profiles, disease activity status, major organ involvements and treatment strategies of these patients at registry. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for scarring alopecia.
Results
We recruited 4792 SLE patients, and 374 (7.80%) patients had scarring alopecia. Mucocutaneous lesions (OR 2.062, p < 0.001), high SLICC/ACR-DI (OR 1.409, p < 0.001) and positive anti-Sm (OR 1.374, p = 0.029) were risk factors for scarring alopecia, while renal (OR 0.714, p = 0.028) and cardio-respiratory involvements (OR 0.347, p = 0.044), and immunosuppressants treatment (OR 0.675, p < 0.001) were significant protective factors.
Conclusions
The prevalence of scarring alopecia in SLE patients is 7.80%. Active treatment strategies should be adopted to prevent scarring alopecia occurring.

Authors: Cho Soo Ick , Yoon Susie , Lee Ho-Jin
Published: August 2020

We aimed to investigate the impact of comorbidity burden on mortality in patients with COVID-19. We analyzed the COVID-19 data from the nationwide health insurance claims of South Korea. Data on demographic characteristics, comorbidities, and mortality records of patients with COVID-19 were extracted from the database. The odds ratios of mortality according to comorbidities in patients with COVID-19 with and without adjustment for age and sex were calculated. The predictive value of the original Charlson comorbidity index (CCI) and the age-adjusted CCI (ACCI) for mortality in patients with COVID-19 were investigated using the receiver operating characteristic (ROC) curve analysis. Among 7,590 patients with COVID-19, 227 (3.0%) had died. After age and sex adjustment, hypertension, diabetes mellitus, congestive heart failure, dementia, chronic pulmonary disease, liver, renal, and cancer were significant risk factors for mortality. The ROC curve analysis showed that ACCI threshold ≥4 yielded the best cut-off point for predicting mortality (area under the ROC 0.92; 95% CI, 0.91–0.94). Our study revealed multiple risk factors that were associated with mortality in patients with COVID-19. The high predictive power of the ACCI for mortality in our results could support the importance of old age and comorbidities in the severity of COVID-19.

AbstractBackground: A novel coronavirus was identified at the end of 2019 in Wuhan City, China. Later, the World Health Organization (WHO) named the disease caused by the virus coronavirus disease 2019 (COVID-19) and declared a pandemic in March 2020. Saudi and global health agencies have provided various COVID-19 knowledge tools and facts to the general public. Therefore, this study aims to assess COVID-19 knowledge among the general public in Saudi Arabia at the early stages of the pandemic, including knowledge of prevention practices, home quarantine measures, and compliance with governmental restrictions.Subjects and methods: A cross-sectional study was conducted in March 2020 during the COVID-19 pandemic in Saudi Arabia. The study included 1006 participants who responded to a random online COVID-19 public knowledge questionnaire that included five sections: demographic characteristics, general knowledge, prevention practices, home quarantine measures, and knowledge of governmental restrictions. Data were collected from a random sample recruited through the circulation of the questionnaire on social media platforms and were then analysed by descriptive statistical methods. Three levels of knowledge were established: excellent, intermediate, and poor. Differences in the percentages of participants with different knowledge levels by the demographic variables were analysed using the chi-square test.Results: Regarding overall general knowledge of COVID-19, 75%, 24%, and 1% of the participants had excellent, intermediate, and poor knowledge levels, respectively. Knowledge levels were significantly different by nationality and age (P=0.027 and 0.008, respectively). The majority of participants (98.4%) reported excellent knowledge of prevention practices, with no statistically significant differences among groups (P>0.005). Older age groups reported higher knowledge of home quarantine measures (86.6% and 86.4% of the 51-60 and older than 60 age groups, respectively, P=0.001). Approximately 50% of Saudis reported excellent knowledge of the restrictions imposed by the Saudi government to control the spread of COVID-19, while approximately 45% of non-Saudis had an excellent level of knowledge (P= 0.009).Conclusion and recommendations: High levels of knowledge about the virus, including prevention practices, are essential. The provision of COVID-19 facts and knowledge tools should be focused on younger generations to enhance compliance with the governmental restrictions required to stop the spread of COVID-19.

A Coronavirus Disease (COVID-19), também denominada por severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), foi descrita pela primeira vez no mês de dezembro de 2019, em Wuhan, na China. Esta disseminou-se por todos os continentes, tendo sido declarada pela Organização Mundial da Saúde (OMS), em 11 de março de 2020, como uma pandemia global. No dia 24de junho de 2020, estavam reportados pela OMS 9.129.146 casos e 473.797 mortes causadas pelo SARS-CoV-2/COVID 19. A transmissão do vírus é feita através de gotículas, embora tenha sido encontrado também nas fezes e no sangue, admitindo-se assim, outros meios de potencial transmissão.  A sintomatologia associada à infeção por SARS-CoV -2 inclui a presença de febre, mialgia ou fadiga, tosse produtiva e/ou tosse não produtiva dispneia, fadiga ou mialgias na maioria dos casos. Existem ainda relatados de sintomas como a cefaleia, dor de garganta, hemoptises e sintomas gastrointestinais como a diarreia, náusea e dor abdominal, mas com menor incidência.
O que torna o professor um “bom professor”?: Carisma e autoridade na escola pública
Authors: Maia Bóris
Published: August 2020

O objetivo deste artigo é apresentar resultados de uma pesquisa sobre as relações de autoridade vigentes nas escolas públicas. De que maneira os professores adquirem legitimidade e exercem a autoridade durante as aulas? É essa a pergunta que orienta este trabalho. Argumento que a relação entre professores e alunos dá-se através de uma autoridade de tipo carismática exercida pelos primeiros. Nesse sentido, adotando uma abordagem processual no estudo do carisma, busco mostrar como as performances desempenhadas pelos professores durante as aulas conferem legitimidade a sua prática profissional, servindo como fonte primordial de atribuição de autoridade na escola. Apresentarei algumas técnicas de ensino que produzem a eficácia simbólica da relação pedagógica, atuando na construção da autoridade carismática do professor. O estudo deriva do trabalho de campo que realizei em uma escola pública do Estado do Rio de Janeiro em 2013, onde acompanhei diariamente as aulas de duas turmas do ensino médio.

Authors: Escóssia Fernanda Melo da
Published: August 2020

O artigo examina audiências judiciais realizadas em um serviço público e gratuito de emissão de certidão de nascimentos num ônibus mantido pelo Tribunal de Justiça do Estado do Rio de Janeiro. Brasileiros adultos sem documento tentam provar à Justiça que são quem dizem ser e, nesse processo, acionam memórias para reconstruir trajetórias. A autora dialoga com o entendimento de Geertz de que o Direito é um saber local e analisa como a decisão judicial resulta de uma operação em que são mobilizadas muitas instâncias – memória, conhecimento jurídico e interpretação –, numa intersecção permanente entre saberes formais e vivências, legalidades e moralidades. O artigo é resultado de dois anos de trabalho etnográfico da autora e inclui parte da pesquisa realizada para sua tese de doutorado, defendida em abril de 2019 no Centro de Pesquisa e Documentação de História Contemporânea do Brasil (CPDOC)/Fundação Getulio Vargas (FGV).
¿Cuánto vale la vida de mi hijo? Una aproximación a las formas de politización de muertes de jóvenes producidas por la policía en la ciudad de Rosario, Argentina, a partir del caso Jonatan Herrera
Authors: Cozzi Eugenia , Di Filippo Marilé
Published: August 2020

El artículo analiza formas de politización de la muerte de jóvenes asesinados por la policía, a partir de la reconstrucción de una intervención teatral que integró el repertorio de protesta con motivo de la muerte de Jonatan Herrera por parte de policías de la provincia de Santa Fe, Argentina; hecho que resultó en un “caso paradigmático”. Dicha intervención teatral fue realizada por familiares, amigos y amigas del joven junto a artistas locales, activistas y militantes de distintas organizaciones sociales, y se diseñó en torno a tres preguntas: ¿Quién era Jonatan Herrera?, ¿cómo lo mataron? y ¿cómo fue el proceso de búsqueda de justicia? Interesa detenerse en esta intervención, por un lado, porque fue una acción que procuró de manera novedosa denunciar, limitar y/o resistir el uso de la fuerza policial, además de permitir indagar prácticas, sentidos y valores asociados a las luchas por la justicia; por otro lado, porque constituyó una intervención significativa dentro de las estéticas de la protesta social en casos de “violencia policial” en esta ciudad. Se sostiene que dicha intervención se constituyó en una instancia relevante de politización de la muerte, en tanto significó una forma de reasignación de humanidad al joven asesinado, a partir de la recomposición de su biografía mientras vida digna de ser vivida; porque implicó una forma de construcción de verdad y justicia, que excedió la arena jurídica y, por lo tanto, supuso una intensa y creativa implicación corporal por parte de sus familiares, amigos y amigas.

My interest here is to consider two ethnographic accounts of Candomblé rituals in Italy and Brazil. I will analyze how Italian practitioners perceive different aspects of the preparation of ritual offerings and what values are at stake in the cooking and consumption of food and food offerings. I will show how memory and the senses are essential to build a new idea of familiarity and to learn new skills within the ritual practice.
A hospitalidade em Paris e Buenos Aires: seguindo consumidores de vinho para além do Rio de Janeiro
Authors: Murgel Luciana Freire
Published: August 2020

O objetivo desse artigo é apresentar como a experiência de trabalho de campo internacional contribuiu para o fazer etnográfico da minha tese de doutorado, que propôs compreender o processo de consumo de vinho de um grupo de pessoas das camadas médias e altas do Rio de Janeiro. Diante das especificidades desse consumo e do meu envolvimento anterior com o objeto de estudo, realizar parte da pesquisa no exterior se tornou tanto estratégia de estranhamento ao familiar como também uma consequência do objetivo de seguir o vinho e seus consumidores de acordo com representações que iam além das fronteiras nacionais. A partir de oportunidades trazidas pelo departamento de antropologia do meu doutorado, pude realizar uma imersão em Paris de nove meses e uma pesquisa exploratória em Buenos Aires de três meses, totalizando um ano fora do país. Tais experiências se tornaram centrais na interpretação dos dados etnográficos, principalmente porque, uma vez vivenciada a hospitalidade enquanto estrangeira nesses países, pude entender como a teoria da hospitalidade era “chave” para a compreensão do meu trabalho de campo no Rio de Janeiro. Isto é, os consumidores de vinho cariocas, ao perceberem o vinho como algo “estrangeiro”, criam relações de hospitalidade com especialistas que trabalham no comércio e que os socializam naquilo que chamam de “cultura do vinho”.
Para cima, Antropólogos: perspectivas ganhas em estudar os de cima
Authors: Nader Laura
Published: August 2020

Neste ensaio, descreverei algumas das oportunidades que os antropólogos têm de “estudar os de cima” (studying up) em sua própria sociedade, na expectativa de fomentar mais discussões sobre o porquê estudamos o que estudamos (NADER, 1964). Os antropólogos têm uma grande contribuição para a nossa compreensão dos processos pelos quais o poder e a responsabilidade são exercidos nos Estados Unidos. Além disso, há uma certa urgência para esse tipo de antropologia preocupada com o poder (Cf. WOLF, 1969), pois a qualidade de vida e as nossas próprias vidas em si mesmas dependem do modo como os cidadãos compreendem aqueles que moldam e realmente controlam as estruturas institucionais. O estudo do homem é confrontado com uma situação sem precedentes: nunca antes tão poucos, por suas ações e inações, tiveram o poder de vida e morte sobre tantos membros da espécie humana. Apresento três razões para “estudar os de cima”: seu efeito estimulante e articulador para muitos estudantes, adequação científica e relevância democrática do trabalho científico. Finalmente, considerarei alguns obstáculos e objeções frequentes e tentarei respondê-los.

Published: August 2020

La industria minera, a pesar de los desarrollos tecnológicos introducidos para humanizar sus procesos, aún se caracteriza por la ejecución de tareas que exigen a los trabajadores elevadas de cargas de trabajo físico y que en muchos casos no son adecuadas desde un punto de vista ergonómico. Esto ha derivado en la aparición de enfermedades ocupacionales, entre las que se destacan los desórdenes musculoesqueléticos. Objetivo: Mostrar los resultados de la evaluación ergonómica de cinco tareas que se ejecutan durante el proceso de desarrollo y construcción de una mina subterránea de Perú. Metodología: Para la evaluación ergonómica fueron seleccionados los métodos Evaluación del Riesgo Individual (ERIN) y Rapid Entire Body Assessment (REBA). Resultados: Las tareas perforación de frente y limpieza de labor presentaron un nivel de riesgo alto según ERIN. Mientras que, en las tareas desatado de rocas, sostenimiento, perforación de frente y voladura, de las 13 posturas evaluadas siete obtuvieron riesgo alto y muy alto, según el método REBA. Conclusiones: La evaluación ergonómica es un paso inicial e importante en el proceso de prevención de desórdenes musculoesqueléticos en la industria minera. La utilización de los métodos ERIN y REBA fue de utilidad para evaluar la exposición a los factores de riesgo e identificar oportunidades de mejora. No obstante, en aras de realizar una prevención efectiva, debe adoptarse un enfoque sistémico que considere factores de riesgo individuales y organizacionales, así como el entorno cultural, político y socio-económico donde se desarrolla la actividad

Los usuarios residenciales del servicio público de agua asumen hábitos y comportamientos que llevan a reducir sus consumos como una estrategia de adaptación a factores cómo el cambio climático, los incrementos en las tarifas del servicio y una medición real y efectiva a través de instrumentos calibrados. Al abordar un estudio de caso, mediante un muestreo no probabilístico de suscriptores de la Empresa de Acueducto y Alcantarillado de la ciudad de Popayán, se determinaron variables cualitativas y cuantitativas que hacen parte del componente técnico, socioeconómico y sociocultural del consumo eficiente de agua potable. Entre las variables cuantitativas se resaltan el tamaño de la vivienda representada en áreas de construcción y jardín, y número de aparatos sanitarios. Variables cualitativas cómo el estrato socioeconómico, tipo de vivienda, antigüedad de la vivienda, existencia de área de parqueo, tenencia de lavadoras de más de 10 años de compradas, características del jefe del hogar, categorías del ingreso familiar, entre otras, inciden en el consumo de los últimos seis meses de los usuarios. Un índice denominado satisfacción del cliente y la suma del número de aparatos sanitarios en el hogar son factores determinantes en la medida que se correlacionan con los consumos bajos en el análisis de correspondencias.
CONSIDERAÇÕES SOBRE ARQUITETURA DE INFORMAÇÃO NA ERA DA UBIQUIDADE
Authors: Agner Luiz
Published: August 2020

Vivemos em um mundo em que a relação entre pessoas, lugares, objetos e empresas são moldadas através da semântica e não mais de uma proximidade física, em que identidades digitais persistem no ciberespaço além da interação com a tela de um computador. Nesse contexto, a Arquitetura de Informação (AI) pervasiva tem se tornado um tema da pós-modernidade: os conceitos de AI evoluíram, ou tiveram seu sentido expandido, ressignificado. Sendo pervasiva, a AI deve ser consistente em uma complexa ecologia - composta de aplicativos, dispositivos móveis e ubíquos, websites, vestíveis, utilitários domésticos conectados, além de outros pontos de contato do cliente com a narrativa transmídia de marcas e organizações. Delineia-se o desafio que coloca os arquitetos de informação e os designers de UX diante da tarefa de repensar seus processos.

La educación es considerada como un servicio, por lo que toda institución educativa sabe de la importancia de sus clientes y reconoce a la calidad en el servicio y la satisfacción de sus clientes como un factor importante para mantenerse en el actual mercado competitivo. Sin embargo, es importante identificar qué dimensiones y variables de una institución educativa satisfacen las necesidades de los clientes. Por esta razón, el objetivo de la investigación fue identificar las dimensiones y variables que contribuyen en la satisfacción de clientes directos (estudiante) e indirectos (padres) de instituciones educativas privadas, en nivel inicial, preescolar, primaria, secundaria, medio superior, superior y capacitación para el trabajo. El método Delphi se utilizó para el diseño y validación del instrumento, el cual quedó conformado por 22 ítems en escala diferencial semántico con valores de 1 a 7 y seis dimensiones: infraestructura, personal docente, servicio administrativo, ambiente, resultados y satisfacción. Para determinar el tamaño de muestra se aplicó un muestreo aleatorio estratificado con asignación proporcional al tamaño del estrato (niveles y escuelas), la muestra fue de 83 escuelas ubicadas en la ciudad de Xalapa-Enríquez, México y 354 clientes. Con un modelo de Ecuaciones Estructurales se encontró que, a excepción de la infraestructura, las cuatro dimensiones restantes mostraron una influencia positiva en la satisfacción, es decir, se encontró un modelo de satisfacción en el que se distinguió el aporte de las dimensiones y de las variables medidas dentro de cada dimensión, sobre la satisfacción de los clientes

The relationship between molecular geometries, crystal structures and charge mobilities of hexathiapentacene (HTP) and three of its derivatives (2Se-HTP, 4Se-HTP, 6Se-HTP) were studied using the density functional theory combined with a hopping mechanism at the molecular and crystal level. The effect of Se substitution on the charge mobility was discussed. The calculated results showed that the derivatives exhibit good planarity and the molecular geometries show little variation during the charge transfer process. The electron mobility is 1.20 cm2 V-1 S-1 for HTP and 2.30 cm2 V-1 S-1 for 6Se- -HTP, which are much larger than the corresponding hole ones, indicating that HTP and 6Se-HTP are good candidates for n-type organic semiconductors. However, 2Se-HTP and 4Se-HTP have comparable hole and electron motilities and are suitable for ambipolar semiconductors.

Budaya organisasi merupakan suatu kebiasaan-kebiasaan yang terjadi dalam tatanan organisasi yang mewakili norma-norma perilaku yang diikuti oleh para anggota organisasi. Dinas Perpustakaan dan Kearsipan Kota Pekanbaru telah menerapkan sistem Informasi Integrated Library System (INLISLite). INLISLite telah digunakan sejak tahun 2015, namun masih terdapat beberapa masalah seperti cenderung mendaftar member langsung ke petugas, cenderung tidak memakai OPAC, petugas tidak cepat tanggap, informasi OPAC tidak lengkap, tidak tersedia koleksi yang dibutuhkan, loker penyimpanan barang tidak terkunci. Metode yang digunakan OCAI dan LIBQUAL+TM model. OCAI terbagi dalam empat tipe budaya organisasi yaitu clan, adhocracy, market, dan hierarchy. LIBQUAL+TM model memiliki empat konstruk yaitu service affect, library as place, personal control dan information access. Tujuan penelitian ini untuk mengetahui pengaruh budaya organisasi terhadap kualitas layanan INLISLite. Sampel yang digunakan sebanyak 97 responden yang merupakan anggota (member) perpustakaan. Pengolahan data menggunakan Microsoft Excel dan SEM-PLS. Hasil penelitian ini adalah budaya dominan yang berjalan saat ini yaitu hierarchy dengan nilai 0,954. Hierarchy merupakan budaya yang sesuai standar peraturan dan prosedur, struktur kerja yang jelas. Pengaruh budaya organisasi terhadap kualitas layanan INLISLite adalah tidak berpengaruh dengan nilai 0,596, dengan tingkat pengaruh nilai harus mencapai (1,96) sehingga hal ini menunjukkan bahwa budaya organisasi tidak mempunyai pengaruh terhadap kualitas layanan INLISLite. Oleh karena itu budaya tersebut tidak meningkatkan kualitas layanan INLISLite.Kata Kunci: Integrated Library System, Kualitas Layanan, LIBQUAL+TM, OCAI, SEM-PLS.
