Get PDFObjetivos: Determinar la efectividad de la Camellia Sinensis frente al Plantago Major en el tratamiento coadyuvante de la gingivitis Huánuco. Materiales y métodos: Se empleó a individuos adolescentes y jóvenes se dividió en dos grupos experimentales A, B y un grupo control siendo el placebo, el tamaño muestral fue determinado por formula de población universal obteniéndose 26 individuos para cada grupo. Metodología: El nivel de investigación es aplicativo, el tipo es cuantitativo, el diseño es cuasi experimental con un estudio clínico de comparación, no aleatorizado, prospectivo, controlado, de tres grupos paralelos, que duro 1 mes, se evaluó la efectividad y la seguridad del uso de una propuesta de colutorio. El diseño de investigación es de un grupo en series de tiempo con múltiples aplicaciones de tratamiento. Resultados: Los colutorios experimentales demostraron efectividad en la reducción de los niveles de índice gingival, índice de placa e índice de sangrado al sondaje con una mayor efectividad en el grupo experimental A en comparación con el grupo experimental B y el grupo control sin presentar significación. El índice gingival presento en su visita a los 30 días en el grupo experimental A 96,2%(25) presentaron una categoría de 0 y 3,8% presentaron una categoría de 1, el grupo experimental B 65,4%(17) presentaron una categoría de 0 y 34,6%(9) presentaron una categoría de 1 y el grupo control 26(100.00%) presentaron una categoría de 3. El índice de placa presento en su visita a los 30 días en el grupo experimental A 100.00%(26) presento una categoría de bueno, el grupo experimental B 100.00%(26) presento una categoría de bueno y el grupo control 100.00%(26) presento una categoría de malo. El índice de sangrado al sondaje presento en su visita a los 30 días en el grupo experimental A 100,00%(26) presentaron una categoría de 0-20, el grupo experimental B 96,2%(25) presentaron una categoría de 0-20, 3,8%(1) presentaron una categoría de 1 y el grupo control 100,00%(26) presentaron una categoría de 100. Conclusión: La Camellia Sinensis (Té verde) tiene mejor efectividad que el Plantago Major (Llantén) como tratamiento coadyuvante de la gingivitis.Tesi
Factores asociados y tendencia en el uso de servicios de salud bucal en niños menores de doce años aplicando regresión Poisson, Perú
Get PDFObjetivo: Analizar los factores asociados y la tendencia en el uso de servicios de salud bucal en niños menores de doce años aplicando regresión Poisson en Perú, utilizando datos de la Encuesta Nacional de Hogares del Instituto Nacional de Estadística e Informática (INEI) para el período 2014-2019. Materiales y Métodos: Se realizó un estudio observacional, analítico, longitudinal y retrospectivo, basado en datos secundarios de la ENDES del INEI. La técnica de muestreo fue por conglomerados, bietápica, probabilística, estratificada e independiente a nivel departamental, por área urbana y rural. Se aplico regresión de Poisson y regresión logística para evaluar la asociación y tendencia. Las variables clave incluyeron el uso del servicio dental (variable dependiente),área de residencia, región natural, e índice de riqueza (variables independientes), así como edad y sexo (variables intervinientes).Se evaluó la bondad de ajuste del modelo de Poisson utilizando Pseudo R2 y el test LR9. Resultados: La prevalencia de utilización del servicio odontológico durante los últimos 6 meses en 2019 fue del 31% en una muestra analizada.El análisis bivariado y la prueba de hipotesis mostró diferencias significativas (p < 0.05) en el uso del servicio dental asociadas con el índice de riqueza, región natural, área de residencia y edad para los años 2014, 2016, 2018 y 2019. En el análisis de regresión Poisson para 2014, 2015, 2016, 2017, 2018 y 2019, se encontró que a medida que aumenta el nivel de riqueza, aumenta la probabilidad de recibir atención dental. Los niños en áreas urbanas mostraron una mayor probabilidad de atención, mientras que residir en la región Selva se asoció con una menor probabilidad. La edad también fue un factor significativamente asociado, con mayor uso observado en niños de mayor edad en el análisis bivariado. Conclusión: Se encontró una asociación estadísticamente significativa entre el uso de servicios de salud bucal en niños peruanos menores de doce años y factores sociodemográficos como el índice de riqueza, la edad, el área de residencia y la región natural. El porcentaje de uso del servicio dental fue bajo. Existe una tendencia de inequidad en el acceso, favoreciendo a poblaciones con mayores recursos económicos.Objective: To analyze the associated factors and trends in the use of oral health services in children under twelve years of age by applying Poisson regression in Peru, using data from the National Household Survey of the National Institute of Statistics and Informatics (INEI) for the period 2014-2019. Materials and Methods: An observational, analytical, longitudinal, and retrospective study was conducted, based on secondary data from the ENDES of the INEI. The sampling technique was cluster, two-stage, probabilistic, stratified, and independent at the departmental level, by urban and rural areas. Poisson and logistic regression were applied to evaluate the association and trend. Key variables included the use of dental services (dependent variable), area of residence, natural region, and wealth index (independent variables), as well as age and sex (intervening variables). The goodness of fit of the Poisson model was evaluated using Pseudo R2 and the LR9 test. Results: The prevalence of dental service utilization during the last 6 months in 2019 was 31% in the analyzed sample. Bivariate analysis and hypothesis testing showed significant differences (p < 0.05) in dental service use associated with wealth index, natural region, area of residence, and age for the years 2014, 2016, 2018, and 2019. Poisson regression analysis for 2014, 2015, 2016, 2017, 2018, and 2019 showed that as wealth levels increased, the likelihood of receiving dental care increased. Children in urban areas showed a higher likelihood of receiving care, while residing in the jungle region was associated with a lower likelihood. Age was also significantly associated, with higher use observed in older children in the bivariate analysis. Conclusion: A statistically significant association was found between the use of oral health services in Peruvian children under twelve years of age and sociodemographic factors such as wealth index, age, area of residence, and natural region. The percentage of dental service use was low. There is a trend toward inequity in access, favoring populations with greater economic resources
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
