Analizar los conocimientos básicos de la tecnología educativa realizando un recorrido histórico hasta la situación actual de la educación en China. Bibliografía. Investigación sobre literatura científica, investigación teórica. Revisión bibliográfica. Análisis de contenido, análisis comparativo, análisis conceptual. La investigación recoge, en la primera parte, los conocimientos básicos sobre la cultura y la comunicación educativa en china, realizando un análisis histórico de la educación en China, profundizando sobre la situación educativa de la última década. La segunda parte está orientada hacia las aportaciones de las tecnologías de la información y la comunicación en el sistema educativo Chino, tanto desde el ámbito formal como no formal y las perspectivas futuras que ofrece la tecnología educativa. El proceso de la educación China está orientado a preparar a los futuros funcionarios gubernamentales; posee un rasgo eminentemente democrático consistente en conceder a todos los habitantes el derecho de desempeñar puestos públicos, aunque sólo los lleguen a desempeñar los más capacitados. Los chinos no cultivan las ciencias por interés científico, sino por ser de interés para el estado; entran en la administración del estado, el cual determina todo lo que debe ser estudiado. Se trata de un estado totalitario regido por 'letrados' no por guerreros ni sacerdotes como sucede a otros pueblos asiáticos. La investigación ha analizado la situación actual de la tecnología educativa en China.

Esta investigación analiza el proceso de adquisición del artículo español en los nominales deverbales con complemento por coreanos adultos en un contexto natural.. Se parte de un estudio contrastivo entre español, segunda lengua y el coreano, lengua materna respecto del artículo. Las peculiaridades del empleo del artículo en estas construcciones en español no se reflejan en la traducción coreana. n este trabajo se parte de las conclusiones aportadas por el estudio contrastivo entre ambas lenguas, para realizar dos pruebas con 20 sujetos coreanos con un nivel alto de español, consistentes en juicios de gramaticalidad y traducción.. Los resultados de ambas pruebas muestran que en la adquisición del artículo del español son decisivas las diferentes manifestaciones de los rasgos pragmáticos, semánticos y aspectuales que afectan a nombres y artículos en la lengua materna y la segunda lengua, respectivamente. Finalmente, se esboza una propuesta de orientación pedagógica basada en las premisas de la 'gramática pedagógica'.

Møller-Plesset (MP2) and Becke-3-Lee-Yang-Parr (B3LYP) calculations have been used to compare the geometrical parameters, hydrogen-bonding properties, vibrational frequencies and relative energies for several X- and X+ hydrogen peroxide complexes. The geometries and interaction energies were corrected for the basis set superposition error (BSSE) in all the complexes (1-5), using the full counterpoise method, yielding small BSSE values for the 6-311 + G(3df,2p) basis set used. The interaction energies calculated ranged from medium to strong hydrogen-bonding systems (1-3) and strong electrostatic interactions (4 and 5). The molecular interactions have been characterized using the atoms in molecules theory (AIM), and by the analysis of the vibrational frequencies. The minima on the BSSE-counterpoise corrected potential-energy surface (PES) have been determined as described by S. Simón, M. Duran, and J. J. Dannenberg, and the results were compared with the uncorrected PES

An improved algorithm for the generation of gridded window brightness temperatures is presented. The primary data source is the International Satellite Cloud Climatology Project, level B3 data, covering the period from July 1983 to the present. The algorithm rakes window brightness, temperatures from multiple satellites, both geostationary and polar orbiting, which have already been navigated and normalized radiometrically to the National Oceanic and Atmospheric Administration's Advanced Very High Resolution Radiometer, and generates 3-hourly global images on a 0.5 degrees by 0.5 degrees latitude-longitude grid. The gridding uses a hierarchical scheme based on spherical kernel estimators. As part of the gridding procedure, the geostationary data are corrected for limb effects using a simple empirical correction to the radiances, from which the corrected temperatures are computed. This is in addition to the application of satellite zenith angle weighting to downweight limb pixels in preference to nearer-nadir pixels. The polar orbiter data are windowed on the target time with temporal weighting to account for the noncontemporaneous nature of the data. Large regions of missing data are interpolated from adjacent processed images using a form of motion compensated interpolation based on the estimation of motion vectors using an hierarchical block matching scheme. Examples are shown of the various stages in the process. Also shown are examples of the usefulness of this type of data in GCM validation.

Convectively coupled equatorial waves are fundamental components of the interaction between the physics and dynamics of the tropical atmosphere. A new methodology, which isolates individual equatorial wave modes, has been developed and applied to observational data. The methodology assumes that the horizontal structures given by equatorial wave theory can be used to project upper- and lower-tropospheric data onto equatorial wave modes. The dynamical fields are first separated into eastward- and westward-moving components with a specified domain of frequency–zonal wavenumber. Each of the components for each field is then projected onto the different equatorial modes using the y structures of these modes given by the theory. The latitudinal scale yo of the modes is predetermined by data to fit the equatorial trapping in a suitable latitude belt y = ±Y. The extent to which the different dynamical fields are consistent with one another in their depiction of each equatorial wave structure determines the confidence in the reality of that structure. Comparison of the analyzed modes with the eastward- and westward-moving components in the convection field enables the identification of the dynamical structure and nature of convectively coupled equatorial waves. In a case study, the methodology is applied to two independent data sources, ECMWF Reanalysis and satellite-observed window brightness temperature (Tb) data for the summer of 1992. Various convectively coupled equatorial Kelvin, mixed Rossby–gravity, and Rossby waves have been detected. The results indicate a robust consistency between the two independent data sources. Different vertical structures for different wave modes and a significant Doppler shifting effect of the background zonal winds on wave structures are found and discussed. It is found that in addition to low-level convergence, anomalous fluxes induced by strong equatorial zonal winds associated with equatorial waves are important for inducing equatorial convection. There is evidence that equatorial convection associated with Rossby waves leads to a change in structure involving a horizontal structure similar to that of a Kelvin wave moving westward with it. The vertical structure may also be radically changed. The analysis method should make a very powerful diagnostic tool for investigating convectively coupled equatorial waves and the interaction of equatorial dynamics and physics in the real atmosphere. The results from application of the analysis method for a reanalysis dataset should provide a benchmark against which model studies can be compared.
