Abstract The objective of this paper is to design a methodology that leads to produce data models arising from the cognitive variables that are obtained from the epistemological interpretation of political discourses originating both in the public and private environments. In such a way that these models can be translated into tools with technological value and consequently economic. As a base document of analysis, the Altenational Nation Project of the political party Movimiento de Regeneración Nacional (Morena), of Mexico, has been used, of whose fifty guidelines the knowledge variables that enclose, or cognitive variables, have been obtained, according to Lamarti (2015), are epistemic correspondence, knowledge, which represents the shared property between cognitive domains: one as an origin and another as destiny. Work was complemented in a documentary way with a grounded qualitative research methodology, by consulting the careers catalog of the INEGI (National Institute of Statistics and Geography) of Mexico, and the correspondence of the subgroups with each of the classified cognitive variables was obtained, then four universities academic programs, and two big companies and one PYME (small and medium enterprises), over their national academic offer and linked to the corresponding cognitive variable. The result was a data model wich serve as tool for retrieve efficiency ratio between careers that form part of the intellectual capital of the companies and the universities' academic offer over each cognitive variable, verifying the efficiency of the designed methodology by adding the amount of careers obtained from the sample among those coinciding with the subgroups assigned to the cognitive variables.

Resumen El objetivo de este trabajo es diseñar una metodología que lleve a producir modelos de datos surgidos a partir de las variables cognitivas que se obtienen de la interpretación epistemológica de los discursos políticos originados tanto en el entorno público como en el privado. De tal suerte que dichos modelos puedan traducirse en herramientas con un valor tecnológico y en consecuencia económico. Como documento base de análisis se ha utilizado el Proyecto Altenativo de Nación del partido político Movimiento de Regeneración Nacional (Morena), de México, de cuyos cincuenta lineamientos se han obtenido las variables del conocimiento que encierran, o variables cognitivas, que de acuerdo a Lamarti (2015), son la correspondencia epistémica, el conocimiento, que representa la propiedad compartida entre los dominios cognitivos: uno como origen y otro como destino. Se complementó la investigación de forma documental con la metodología de una investigación cualitativa fundamentada, consultando el catálogo de carreras del Instituto Nacional de Estadística y Geografía (INEGI) de México, y se obtuvo la correspondencia de los subgrupos con cada una de las variables cognitivas clasificadas, después se analizó individualmente cada programa académico de cuatro universidades, dos empresas grandes y una PYME (pequeña y mediana empresa), sobre su oferta académica a nivel nacional y se vinculó con la variable cognitiva correspondiente. Se obtuvo como resultado el modelo de datos que sirvió como herramienta para obtener la relación de eficiencia entre las carreras que forman parte del capital intelectual de las empresas y la oferta académica de las universidades con respecto a cada variable cognitiva, comprobando la eficiencia de la metodología diseñada al sumar el número de carreras obtenidas de la muestra entre aquellas coincidentes con los subgrupos asignados a las variables cognitivas.

To determine the optimum level of crude protein (CP), a meta-analysis with data of seven trials with 240 hybrid nursery pigs individually penned with average body weight 12.57 kg. Growth performance, carcass characteristics, and plasma urea nitrogen concentration were evaluated. ANOVA and regression analysis were performed using a surface response model with RSREG of SAS procedure considering the crude protein (CP) level as well as the effect of trial, year and season; the optimum CP levels were determined to each variable (average daily body gain= 19.25, dorsal fat= 18.1, feed:gain ratio= 17.3 and plasma urea N= 16.5 %), and were corroborated with an additional experiment using 40 hybrid nursery pigs with 11.5 kg of initial weight during 21 d, in a completely randomized design with ten replicates per treatment. The meta-analysis indicated that average daily gain, lean meat gain and plasma urea nitrogen concentration were reduced when CP was lowered (p≤0.05); feed/ gain ratio was improved when CP was reduced (p≤0.05). In the experiment conducted to corroborate the optimum CP levels, there was no difference in the analyzed variables, except the percentage of lean meat, that improved (p≤0.05) when pigs were fed 16.5 and 19.25 % CP. The results indicate that the optimal level of CP is 16.5 % for nursery pigs diets based on sorghum-soybean meal with synthetic AA added, because of at this level of CP, neither production variables nor carcass characteristics were affected and urea concentration in plasma decreased.

Para determinar el nivel óptimo de proteína bruta (PB) se realizó un meta-análisis con datos de siete experimentos con 240 cerdos híbridos de aproximadamente 37 días de edad y peso vivo inicial promedio de 12,57 kg en fase starter y alojados individualmente. Se evaluó el comportamiento productivo, características de la canal y concentración de urea en plasma. Se realizó análisis de varianza y de regresión utilizando un modelo de superficie de respuesta con el procedimiento RSREG de SAS tomando en cuenta el nivel de PB y el efecto del experimento, año y época del año; se determinaron los niveles óptimos de PB para cada variable (ganancia diaria de peso= 19,25; grasa dorsal= 18,1; conversión alimenticia= 17,3 y urea en plasma= 16,5 %), los cuales se corroboraron con un experimento adicional utilizando 40 cerdos híbridos en fase starter de 36 días de edad con 11,5 kg de peso inicial durante 21 días, en un diseño completamente al azar con diez repeticiones por tratamiento. El meta-análisis indicó que la ganancia diaria de peso, ganancia de carne magra y urea en plasma disminuyen al bajar la PB (p≤0,05); y la conversión alimenticia mejora cuando se reduce la PB hasta 16,5 % (p≤0,05). En el experimento realizado para corroborar los niveles óptimos de PB, no hubo diferencias en las variables analizadas, excepto para porcentaje de carne magra, que mejoró (p≤0,05) cuando se utilizaron 16,5 y 19,25 % PB. Los resultados indican que el nivel óptimo de PB es de 16,5 % para cerdos en fase starter con dietas a base de sorgo-harina de soja adicionadas con AA sintéticos, ya que en este nivel de PB no se afectan las variables productivas, características de la canal y se disminuye la concentración de urea en plasma.

The effect of D002, a defined mixture of higher primary alcohols purified from bee wax, on in vivo and in vitro lipid peroxidation was studied. The extent of lipid peroxidation was measured on the basis of the levels of thiobarbituric acid reactive substances (TBARS). When D002 (5-100 mg/kg body weight) was administered orally to rats for two weeks, a partial inhibition of the in vitro enzymatic and non-enzymatic lipid peroxidation was observed in liver and brain microsomes. Maximal protection (46%) occurred at a dose of 25 mg/kg. D002 behaved differently depending on both the presence of NADPH and the integrity of liver microsomes, which suggests that under conditions where microsomal metabolism was favored the protective effect of D002 was increased. D002 (25 mg/kg) also completely inhibited carbon tetrachloride- and toluene-induced in vivo lipid peroxidation in liver and brain. Also, D002 significantly lowered in a dose-dependent manner the basal level of TBARS in liver (19-40%) and brain (28-44%) microsomes. We conclude that the oral administration of D002 (5, 25 and 100 mg/kg) for two weeks protected rat liver and brain microsomes against microsomal lipid peroxidation in vitro and in vivo. Thus, D002 could be useful as a dietary natural antioxidant supplement. More studies are required before these data can be extrapolated to the recommendation for the use of D002 as a dietary antioxidant supplement for humans.
