APLICACIóN DEL CUADRO DE MANDO INTEGRAL Y EL DATA WAREHOUSE A LA GESTIóN DE LOS RECURSOS HUMANOS
Carlos Ramón López Paz
Ingeniería Industrial , 2006,
Abstract: Actualmente la gestión de los recursos humanos (GRH) trasciende de la tradicional administración del personal que se centra en ella desde una perspectiva muy funcional. En tal sentido, los estudios en el área están abogando por procedimientos más integradores y con un fuerte soporte de las tecnologías de la información y las comunicaciones que analicen todos los procesos queacontecen en una empresa desde perspectivas, tanto internas como externas, con un enfoque transfuncional. El presente trabajo se propone esbozar el marco conceptual que implica el dise o de una propuesta inicial del modelo de sistema de información para el control estratégico de la GRH. En tal sentido se abordan las temáticas relativas a: los Sistemas de información, el data warehouse y el cuadro de mando integral. Finalmente se comenta un posible campo de aplicación de la referida propuesta inicial de modelo en las empresas cubanas que cuentan con la herramienta GREHU.

López,René; Arismendi,Marlene; Sáez,Juan Carlos; Godoy,Iván; Ocaranza,María Paz;
Revista chilena de cardiología , 2011, DOI: 10.4067/S0718-85602011000200008
Abstract: background: ischemia / reperfusion (ir) is relevant in the myocardial loss of cardiomyocytes through apoptosis. during ir, hemi channels (hc) allow the entry of proapoptotic substances to the cell. boldine, a compound extracted from peumus boldus, has proven to be antioxidant and to block hc. objective: to determine the effect of boldine on cardiomyocyte apoptosis in rats subjected to ir. methods: male rats, body weight (bw) 200 g, were subjected to reversible ligation of the left coronary artery for 30 minutes (i) and subsequent reperfusion (r) for 24 hours. a subset of these animals (ir+b) received an intraventricular dose of boldine (40mg/kg) and then two doses via gavage (75 mg/kg) at 30 and 60 minutes post-r. sham operated rats (s) receiving the same treatment were used as controls. we determined body weight (bw), relative heart mass (rhm) and systolic blood pressure (sbp). percentage of apoptotic cardiomyocytes (cmap), other apoptotic cells (ocap) and total apoptotic cells (tcap) were determined by tunel. activation of metalloproteinases (mmps) 2 and 9 was determined by zymography and mcp-1 mrna levels by rt-pcr. results: compared to ir alone, ir+boldine did not change bw or rcm, but significantly decreased pas, tcap (71 ± 2.4 vs 57 ± 1.5, p=0.016) and cmap (69 ± 1.5 vs 44 ± 0.4, p=0.016). no difference was observed in the ocap, mmps activity and mcp-1 mrna levels. conclusions: boldine decreased sbp and post-ir cardiomyocyte apoptosis without effect on other cells. this effect was not mediated by mmps activity or mcp-1 gene expression.

Abstract: high density foliage crops produce the rapid saturation of the red band and reduction of variations in curve slopes of the same vegetation (iso-lai), on which many vegetation indexes (vi) are based. for this reason, it is important to develop alternative indexes that do not become saturated and that are easily parameterized with information from the field. to this end, temporal patterns of spectral indexes (expo-linear model as reference) were evaluated based on the slopes of the iso-lai lines, as well as the biophysical variables aerial biomass (bm), aerial cover (fv) and height (h) of two crops with different foliage density: high (sorghum) and medium (cotton). when an expo-linear model is applied, it is expected that it would have a bi-linear pattern, as long as the variables coincide in their initial and end phases. in general, the bm exponential and linear phases do not coincide with those of fv and h; this shows that there are differences among the structural characteristics, those of spatial vegetation distribution (fv and h), and photosynthetic function (foliage and biomass). the medium density crop exhibited well-characterized bilinear patterns. in contrast, the high density crop saturated rapidly in the exponential phase of bm. to reduce the problem of saturation, the use of the additive constant a0 was explored as an alternative to the indexes based on slope. the relationship between the additive constant and bm exhibited patterns of the double expo-linear type with problems in the definition of its transitions; the relationship with the variable fv were bi-linear, both for the medium density crop and for the high density crop, thus facilitating parameterization the vegetation indexes (use of fv) in the field; with height, the relationship was linear-exponential.

Abstract: Introducción: en el mundo se ha obtenido y estudiado la composición de vinagres de diferentes especies de bambúes, los cuales son ampliamente utilizados en los países orientales para elaborar diferentes productos farmacéuticos y alimentarios. La especie Guadua angustifolia Kunth (guadua) es autóctona de Colombia y otros países vecinos. Sin embargo, con esta especie no se conocen desarrollos similares. Es necesario obtener y caracterizar sus principales componentes y comparar si tienen una composición similar para definir su uso como materia prima en formulación de productos farmacéuticos y alimentarios de valor agregado, además de contribuir con el desarrollo de la cadena de la guadua en Colombia. Objetivos: obtener vinagre de guadua y conocer sus principales componentes. Métodos: el vinagre de guadua se obtiene durante las etapas preliminares de la producción de carbón a partir de residuos de guadua, a temperaturas alrededor de 200 °C. Estos vinagres se recogen, se filtran y se examinan sus características fisicoquímicas. Las fracciones ácida, básica y neutra se analizan por cromatografía de gases acoplada a espectrometría de masas. Resultados: el vinagre de guadua obtenido es un líquido ligeramente amarillo, con olor a humo. Los principales productos encontrados son el ácido acético, el p-guayacol, el fenol, el siringol. Conclusiones: los componentes son similares a los reportados por otros investigadores en otras especies de bambúes y permiten demostrar el potencial del vinagre de guadua para su aplicación en el desarrollo de productos farmacéuticos y alimentarios.

Abstract: introduction: adverse drug reactions (adrs) are an important cause of morbidity and mortality among hospitalized patients. objectives: this study was designed to describe the frequency, severity, and causality of adrs in internal medicine units at a third-level university hospital. materials and methods: a descriptive study was performed at internal medicine units, by means of a structured format, review of clinical records, and interview of hospitalized patients. the naranjo algorithm was applied to patient adverse events to define causality. additionally, adrs were classified according to the rawlins and thompson criteria. results: one hundred patients (50 men and 50 women) were included in the study. ninety nine (99) adverse events were found among the patients. the naranjo algorithm was applied to adverse events, resulting in twenty nine (29) probable adrs, twenty (20) possible adrs and fifty (50) doubtful adrs. cardiovascular drugs and antibiotics were the most frequent therapeutic groups associated with adrs. in addition, two preventable medication errors were identified. conclusions: frequency of adrs was similar to the number reported in other studies in internal medicine units. it is necessary to systematize efforts of pharmacological surveillance in hospital wards, toward an opportune detection and prevention of adrs.
Hibridación natural entre Pinus oocarpa y P. Pringlei
Javier López Upton,Valentín Velazco Fiscal,Jesús Jasso Mata,Carlos Ramírez Herrera
Acta botánica mexicana , 2001,
Abstract: Se determinó la existencia de hibridación natural entre P. oocarpa Schiede ex Schlechtendal y P. pringlei Shaw analizando una muestra de 30 árboles que habitan naturalmente en simpatría y que incluyó individuos catalogados como híbridos putativos. El área de hibridación se localiza en el municipio de Ario de Rosales, Michoacán. Se utilizó un análisis discriminante de variables canónicas con 19 características morfológicas y anatómicas de acículas, conos y semillas. Los árboles inicialmente catalogados como híbridos putativos resultaron con valores intermedios en la mayoría de las características estudiadas. De éstas las que mayormente contribuyeron en las funciones de discriminación canónica y en la separación de las especies progenitoras de los árboles híbridos en estudio, resultaron ser el número de acículas por fascículo, el de hileras de estomas en la cara dorsal, el de canales resiníferos internos y septales, así como la longitud del pedúnculo y el diámetro del cono. Un segundo análisis discriminante fue realizado con muestras de diez árboles de P. oocarpa y siete de P. pringlei de rodales puros habitando alopátricamente y los de los 30 árboles del rodal en simpatría. El análisis gráfico indicó que los árboles de cada especie se aglomeraron opuestamente unos de otros, aunque los individuos de los rodales puros lo hicieron ligeramente hacia los extremos, lo que puede indicar un posible proceso de infiltración genética en el área de hibridación en estudio.
