ABSTRACT

l objetivo de este trabajo es establecer una metodología apropiada para seleccionar una revista para publicar en el área biotecnológica, a través del proceso analítico jerárquico. La publicación de artículos en revistas indizadas es una de las metas fundamentales del trabajo de investigación científica. Por eso es importante seleccionar la revista que mejor proyecte la información del artículo entre la comunidad técnico-científica; sin embargo, depender de criterios subjetivos puede derivar en la pérdida de tiempo y energía, costos innecesarios y una baja difusión de la productividad científica del investigador. Para establecer la metodología se evaluaron 11 parámetros cualitativos y cuantitativos de 20 revistas científicas, validadas por un grupo de expertos en el área, luego se usó un proceso de análisis jerárquico con lo que se estableció el criterio de selección. Se encontró que los elementos clave para considerar la selección de una revista son el factor de impacto, el tiempo de aceptación, el tipo de indización y la cantidad de artículos publicados por la revista. De esta forma, con una metodología para escoger la revista idónea, se puede aumentar las posibilidades de publicar el artículo, disminuir el tiempo de espera, gastos de publicación y lograr tener un mayor número de citas una vez publicado, usando una diversidad de criterios y no únicamente criterios bibliométricos como el factor de impacto.


he aim of this study is to establish an applicable methodology for the selection of a journal when aspiring to publish a scientific work in the biotechnology field, using the hierarchical analytical process. The publication of papers in indexed journals is one of the main goals of scientific research work. That's why it is of great importance to select the journal that best disseminates the information of the paper among the technical-scientific community; however, having to rely on subjective criteria in the journal selection process can result in time and energy waste, unnecessary costs and a low dissemination of the researcher's scientific productivity. To establish the methodology, 11 qualitative and quantitative parameters of 20 scientific journals were evaluated, validated by a group of experts in the area, followed by a hierarchical analysis process, which established the selection criteria. It was found that the key elements to consider the journal selection are the impact factor, the acceptance time, the type of indexing and the number of articles published by the journal. Thus, with a methodology to choose the appropriate journal, it is possible to increase the possibilities of publishing the article, decrease the waiting time, publication costs and achieve a larger number of citations once published, using a variety of criteria and not just bibliometric criteria as the impact factor.

ABSTRACT

Com o objetivo de se estudar o efeito do tipo de envase sobre a criopreservação do sêmen asinino, coletado de forma fracionada, utilizou-se o sêmen de cinco jumentos da raça Pêga, submetido a um protocolo de congelamento envolvendo um diluidor e duas formas de envase, flatpacks ou palhetas de 0,55mL, tendo como ponto final a avaliação dos parâmetros seminais in vitro após o descongelamento do sêmen. Os resultados de motilidade espermática para as amostras envasadas em flatpacks ou em palhetas foram de 24,67% e 35,34%, no momento do descongelamento; de 13,39% e 25,83%, 60 minutos após o descongelamento; e de 7,86% e 13,33%, aos 120 minutos após o descongelamento, respectivamente. Já os valores para o vigor espermático foram de 2,55 e 3,33, no momento do descongelamento; de 1,57 e 2,48, após 60 minutos do descongelamento; e de 1,11 e 1,67, após 120 minutos do descongelamento, na mesma ordem anterior. As características seminais diferiram entre os jumentos, evidenciando uma grande variação individual. O percentual de ejaculados aprovados (motilidade ≥30%, vigor ≥3) foi influenciado pelo reprodutor e pelo tipo de envasamento, estando o melhor resultado (P<0,05), de 86,21%, associado ao sêmen envasado em palhetas, quando comparado ao valor de 56,67%, obtido para o sêmen envasado em flatpacks.


The effect of the type of package on the cryopreservation of jackass semen was studied, using the sperm-rich fraction of five jackasses and a special cryopreservation semen protocol, related to one extender and two different packages, FlatPacks or straws. The characteristics of the in vitro semen were evaluated after thawing. The motility results were 24.67% and 35.34% after thawing; 13.39% and 25.83% 60 minutes after thawing and 7.86% and 13.33%, 120 minutes after thawing. The vigor results were 2.55 and 3.33 after thawing, 1.57 and 2.48 60 minutes after thawing and 1.11 and 1.67 120 minutes after thawing, for FlatPacks or straws packages, respectively. The jackasses used were different regarding seminal characteristics, with great individual variation. The approved post-thaw viability (motility ≥ 30%, vigor ≥ 3) was affected by jackass and type of package, with the best results (P<0.05) for semen packed in straws (86.21%), compared to semen packed in FlatPacks (56.67%).
