When the whole analysis ends, the methodology level, the tool level, the competence development level, the portfolio and programs methodology level, the project management office level, we can have a clearer idea about the culture of Bogota companies' projects. This study concludes that the maturity level of all these companies' projects is low 46,9 % in big companies, percentage that is reduced to 24,7 % when it is related with big companies 13,6 % in medium- size companies 8,6 % in small companies, and 6,2 % very small companies. The population sample was conformed by 5,187 companies of more than ten employees and a sample of 226 companies. This research has an exploratory character to define the different investigation lines for project management programs. This article aims at describing the maturity level of companies in Bogota, Colombia, being requested in two different dimensions: on one hand, the degree of fulfillment according with each process of standardization, measurement, control and systematic improvement of project management processes on the other hand, the connection among portfolio, programs and projects. En consecuencia, se rechazó la hipótesis nula donde se dijo que la optimización de costos en los proyectos no depende de los factores clave de rendimiento y se aceptó la hipótesis de investigación en la cual se planteó que los factores clave de rendimiento tiene un impacto positivo en la optimización de costos. Factor de Desempeño del Proceso, no tuvo ninguna correlación significativa con la variable dependiente. El F4.Factor Ambiental con la dimensión Y3.Determinar el Presupuesto de 0.573** y en Y1.Estimación de Costo de 0.427*. El F2.Factor de Riesgos y Problemas, con la dimensión Y3.Determinar el Presupuesto y con Y4.Control de Costos. Posteriormente mediante el análisis de correlación de Rho Spearman, se encontró una correlación significativa positiva media del F3.Factor Organizacional con las cuatro dimensiones de la variable independiente. A través del análisis factorial, fue posible determinar 11 indicadores que explicaron el 81.741% de los 26, agrupándolos en 4 factores: F1.Factor de Desempeño del Proceso, F2.Factor de Riesgos y Problemas, F3.Factor Organizacional y F4.Factor Ambiental.
Las variables fueron factores clave de rendimiento (independiente) y optimización de costos (dependiente). Se muestra un enfoque cuantitativo, descriptivo-correlacional, con diseño no experimental, de corte transversal, la unidad de análisis fue empresas medianas manufactureras de Tecate, Baja California, México, se realizaron 31 encuestas a gerentes de proyectos. The results of the laboratory tests and the theoretical analysis conducted to determine the increment of the protection ratio required by the presence of these amplifiers are presented in part II.El propósito de esta investigación fue determinar los factores mediante los indicadores clave de rendimiento, conocido por sus siglas en inglés Key Performance Indicators (KPI) y su impacto en la optimización de costos en proyectos.
Finally, it has been found that an important part of the interference problems is due to the amplifiers of the master antenna television (MATV) systems in buildings. The required power ratio depends on the specific shape of the radiation pattern of each antenna.

The power ratios between digital and analog TV signals at the broadcasting station should be adjusted to meet the protection ratios everywhere within the coverage area. As stated in ETSI documents (see ETSI TR-101-190, 1997), the use of a different antennas for DVB-T may require ERP restrictions to protect existing analog services. Another source of problems is use of different radiation elements at the same site for broadcasting DVB-T and analog TV signals. It has been found that the frequency plan is part of the source of the interference problems, particularly in the case of cochannel interference. This paper, part I, describes the field measurements, whereas the laboratory measurements and the poll results are described in part II (see Acuna, M.A.
The main objective is the identification and explanation of the interference problems reported since the start of DVB-T broadcasting.
The research work covers field measurements, laboratory measurements, a theoretical evaluation of the interference problems and a national survey among TV installation companies. The results of an extensive study on analog PAL signals interfered with by digital DVB-T signals are presented.
