    Este trabalho foi desenvolvido com o objetivo de avaliar a qualidade dos painéis compensados do tipo “combi”, produzidos com lâminas de Eucalyptus grandis e Eucalyptus maculata como capa e contracapa, e lâminas de Pinus taeda como miolo, visando sua aplicação como piso laminado com montagem direta. Os painéis foram produzidos com resina fenol-formaldeído e melamina-uréia-formaldeído. As avaliações do coeficiente de redução em espessura, resistência da linha de cola, flexão estática e dureza Janka demonstraram que os painéis produzidos com capa e contracapa de E. maculata e miolo com P. taeda, com uso tanto de resina fenol-formaldeído quanto de melamina-uréia-formaldeído, foram os que apresentaram melhores propriedades para uso como piso laminado de madeira. Os resultados indicam ainda a possibilidade de utilização do processo de “montagem direta” para fabricação de pisos laminados.This research was developed aiming to evaluate the quality of plywood manufactured using veneer of Eucalyptus grandis and Eucalyptus maculata as face layer and Pinus taeda as core, to use for laminated wood flooring. The boards were manufactured with phenol-formaldehyde and melamine-urea-formaldehyde resins. The evaluation of the coefficient of thickness reduction, glue line strength, bending strength and surface hardness, showed that the boards made from E. maculata as face layer and P. taeda as core, using with phenol-formaldehyde and melamine-urea-formaldehyde resins, presented the better properties to use as laminated wood flooring. The results also showing the possibility to use the direct assembly method to laminated flooring manufacture

    About half of students are planning to enter labor force after graduating from high schools in Japan, so job placement is an integral part of the vocational guidance in high school. It means high school plays an important role in allocating students to labor market. If we try to grasp the selection function of Japanese high schools totally, we have to clarify these allocation processes. In order to explore the processes, we made a nationwide survey including 1,170 high schools (whereby more than half of the students planning to work upon leaving school) using questionnaire method. This is the first report of the survey

    A computational complexity of decision procedure for the intuitionistic logic without weakening rule

    Non-classical logics have been studied to realize some logics we use in our everyday lives, and have something to do with the resource problem in Computer Science. In this paper we discuss such non-classical logics from viewpoints of decidability and computational complexity. We deal with a system FLec in Gentzen-type sequent calculus (LJ) without the weakening rule, which is also an intutionistic relevant logic without distributive law. We proved in our previous paper that the propositional logic FLec is decidable in a non-constructive way. In the present paper we give an upper bound for the decision procedure by using McAloon’s ideas
