Juegos para colorear grafos

En este trabajo se presentan aplicaciones informáticas de carácter lúdico y didáctico, que tienen como objetivo la comprensión de las estrategias para colorear grafos. La primera de ellas es un juego de dos jugadores (uno de ellos puede ser el ordenador) en el que, alternativamente, cada jugador colorea un vértice de un grafo previamente construido. Los colores se eligen de una lista adecuada para cada grafo. Vence el primer jugador si consigue que, en algún momento, el segundo jugador no disponga de ningún color válido para seguir coloreando el grafo. Si, por el contrario, el grafo se colorea correctamente, el vencedor es el segundo jugador. La segunda aplicación es también un juego decoloración de grafos, pero en esta ocasión se colorean las aristas. Ambas aplicaciones disponen de un banco de grafos del que se elige uno en cada nuevo juego

Principios jurídicos de organización

Summarium Omnibus qUidem notum est Concilium Vaticanum 11 impulisse (multoties etiam instituisse) motum in Toto mutationum organorum in Ecclesia. Copiosa iIIa postconciliarls legum editio signum est manifestum pro dictis. Eiusmodi factum organizativum perpendi potest e diversis prospectibus. Nostra interest perpendere e solo prospectu organizativo, scilicet quod attinet ad technican (artem) definitam quae maiorem efficaciam prae• bet utilitati finium pastoralium. Ideo fit necessarium illam cognoscere technicam, i. e., iIIa iuridica principia quodlibet motum organizativum inspirantia. Hoc studium inseritur isti demum contextui. Cum elucet quonam consistunt, ut technice fertur, illa principia, tum quid eorundem applicatio afterat organizationi ecclesiasticae exponit. Agitur suggerentia criteriorum fundamentalium, generalium principiorum ac organizativae expostulationes quas sibi vindicat vel exigit, tempore hodierno, gravis conatus efficacem organizationem ecclesiasticam instituendi. In specie studet principiis luridicis, ut aiunt, deseentra'libationis, desconcentrationis organicae functionum, hierarchiae, coordinationis ac consultationis. Res his enuntiationibus inclusae sunt vere implicatae cum ad cardines eccleslasticae organizationis referantur. Summas quaestiones adet pro mutatione structura• rum potestatis, iurldlca eius exercitationis normativa, ecclesiastica gubernatione, necessaria unitate et coor• dlnatione, etc, Quaestlones qUidem actualissimae quipus primas deftert attentio, praesentlbus rerum adiunctis, et doctrinae et lpsae ecclesiastlcae auctoritatls. --------------------------------------------- Abstract As is well known, Vat. 11 has stimulated (and in many cases established) a movement of reforms in the Church, reflected in great part by the abundantpostconciliar legislation in this regard. Su eh a phenomenon can beevaluated from different points of view, but we would like to view it from a strictly organizational perspective, that is, insofart as it is a concrete technique which ofters a greater efficacy in the service of pastoral goals. A knowledge of said technique is therefore indispensable, insofar as it is composed of juridicalprinciples which inspire any organizational phenomenon. On the one hand this work emphasizes in what these principies consist technica•lly. and on the other hand, in what their application to eclesiastical organization carries with it. The author suggests basic criteria, general principies, and organizational factors which demand a serious attempt to establish an efficient ecclesiastical organization, in present-day circumstances. Included in the study are the so-called juridical principies of decentralization, organic desconcentration of functions, hiérarchy, coordination and consultation. The underlying issue is truly complex, referring as It does to capital points of ecclesiastical organization. Important questions are thus dealt with: the change of power structures, the juridical regulation of its exercise, ecclesiastical government, necessary unity and coordination, etc. AII in all, a truly relevant theme in present day life, concerning both doctrine and ecclesiastical authority
