El propósito de esta investigación fue construir un instrumento de evaluación del desempeño técnico-táctico de los jugadores de vóleibol, que posibilite la toma de decisión por parte del entrenador. Las variables de estudio fueron la evaluación del desempeño técnico de los jugadores de vóleibol y la evaluación del desempeño táctico de un equipo de vóleibol, a través del programa Microsoft Office Excel®, que permitió registrar y acceder en tiempo real a la información durante el desarrollo de un partido. La evaluación de desempeño técnico abarcó fundamentos técnicos, con su respectiva categorización de valores. La evaluación de desempeño táctico del equipo se compuso por la organización de la levantada, el porcentaje de eficiencia técnica del ataque en k1 y k2, y el análisis de distribución de levantada y eficiencia de ataque por rotación. El programa consiste en 6 libros de Excel® que trabajan de manera interrelacionada. Los primeros cinco corresponden a los sets jugados y el sexto, al resumen de toda la información ingresada. Las hojas se dividen en: Activas (Hoja final, hoja general, hoja diferencia, hoja atqefi, hoja análisis atqk2 y hoja resumen por jugador), Intermedias (Datos y ATAQRSM), y Pasivas (Tablas). El instrumento de evaluación desempeño técnico-táctico aporta y desarrolla en el ámbito de la evaluación objetiva de los rendimientos técnicos-tácticos. Este instrumento presenta características de bajo costo y fácil operación constituyen fortalezas que beneficiarán a todos aquellos entrenadores que lo utilicen. Abstract. The purpose of this study was to build an instrument for evaluating the technical-tactical performance of the volleyball players, which enables a decision making by the coach. The study variables were the evaluation of the technical performance of the volleyball players and the evaluation of the tactical performance of a volleyball team. A computer tool for evaluating the technical-tactical performance of volleyball players was developed. Through a computer program established in Microsoft Office Excel, which allowed registering and immediately accessing the necessary information during the development of a game. The variable of technical performance evaluation covers the following technical foundations, with their respective categorization of values. The tactical performance evaluation variable of the team was composed by the distribution of the raised, the technical efficiency percentage of the attack in k1 and k2, and the analysis of raised distribution and efficiency of attack by rotation. The program consists of 6 Excel books that work in an interrelated manner. The first five correspond to the sets played and the sixth corresponds to the summary of all the information entered. The match data were entered in the story sheet, to codify the technical-tactical situations of the game full. The sheets are divided into: Active (Final sheet, general sheet, difference sheet, atqefi sheet, atqk2 analysis sheet and summary sheet per player), Intermediate (Data and ATAQRSM), and Passive (Tables). The instrument of statistical evaluation of the technical-tactical performance of volleyball players serves as a contribution to the entire national volleyball environment, for its development in the field of objective evaluation of technical performances. This instrument its low cost and easy operation are strengths that will benefit all those coaches that use it.

Hierarchy Process

The proper performance evaluation relies on the construction of the scientific, reasonable, and feasible indices system. The balanced score card (BSC) works as good basis for the strategy of the commercial bank. It is a series of financial evaluation indices and non-financial evaluation system which provides prompt, overall, and objective support for managements to understand the operation situation. The AHP, a hierarchy weighted decision method, is used for complicated, over-ruled and un-quantified problems, it will relate the objective evaluation with the decision maker’s subjective judgment and reasoning, quantify the reasoning of the decision maker, avoid the logic mistakes the decision maker might make when dealing with complicated, or multiple projects. Using AHP with the basis of the evaluation indices of the BSC will form a whole construction of the evaluation system which reflects the basic situation of the commercial bank clearly.

Product evaluation is very important for product improvement and development, and subjective product evaluation determines customer’s evaluation of products to some extent, so the purpose of this study is to establish a reasonable subjective product evaluation system. In this study, we comprehensively determine the evaluation indexes based on Kansei engineering (KE), establish an overall product evaluation system by using analytic hierarchy process (AHP), and establish the subjective product evaluation system by classifying the evaluation indexes in the overall product evaluation system into “objective evaluation index” and “subjective evaluation index”, removing the objective evaluation indexes, and retaining the subjective evaluation indexes. Additionally, we select some modern chairs as experimental samples to verify the reliability and validity of this subjective product evaluation system by means of questionnaires. The experimental results show that, in this subjective product evaluation system, the subjective evaluation of the product is positively correlated with the “favorite” level of the product in comprehensive evaluation, and negatively correlated with the “least favorite” level of the product in comprehensive evaluation, indicating that this subjective product evaluation system realizes a symmetry between subjective product evaluation and comprehensive product evaluation. Therefore, it can be concluded that this subjective product evaluation system based on KE and AHP proposed in this study has reliability and validity, and can be used for product evaluation to judge the popularity of products and enhance the competitiveness of products.

Abstract This paper presents an overview of the general chemical principles underlying the structures, synthesis and technical performance of azo pigments, the dominant chemical class of industrial organic pigments in the yellow, orange, and red shade areas, both numerically and in terms of tonnage manufactured. A description of the most significant historical features in this group of pigments is provided, starting from the discovery of the chemistry on which azo colorants are based by Griess in the mid-nineteenth century, through the commercial introduction of the most important classical azo pigments in the early twentieth century, including products known as the Hansa Yellows, β-naphthol reds, including metal salt pigments, and the diarylide yellows and oranges, to the development in the 1950s and 1960s of two classes of azo pigments that exhibit high performance, disazo condensation pigments and benzimidazolone-based azo pigments. A feature that complicates the description of the chemical structures of azo pigments is that they exist in the solid state as the ketohydrazone rather than the hydroxyazo form, in which they have been traditionally been illustrated. Numerous structural studies conducted over the years on an extensive range of azo pigments have demonstrated this feature. In this text, they are referred to throughout as azo (hydrazone) pigments. Since a common synthetic procedure is used in the manufacture of virtually all azo (hydrazone) pigments, this is discussed in some detail, including practical aspects. The procedure brings together two organic components as the fundamental starting materials, a diazo component and a coupling component. An important reason for the dominance of azo (hydrazone) pigments is that they are highly cost-effective. The syntheses generally involve low cost, commodity organic starting materials and are carried out in water as the reaction solvent, which offers obvious economic and environmental advantages. The versatility of the approach means that an immense number of products may be prepared, so that they have been adapted structurally to meet the requirements of many applications. On an industrial scale, the processes are straightforward, making use of simple, multi-purpose chemical plant. Azo pigments may be produced in virtually quantitative yields and the processes are carried out at or below ambient temperatures, thus presenting low energy requirements. Finally, provided that careful control of the reaction conditions is maintained, azo pigments may be prepared directly by an aqueous precipitation process that can optimise physical form, with control of particle size distribution, crystalline structure, and surface character. The applications of azo pigments are outlined, with more detail reserved for subsequent papers on individual products.
