The article deals with computer graphics tasks related to the activities of the future informatics teacher in conditions of fundamentalization of education. Training of future informatics teachers in the context of the fundamentalization of education requires them to know the range of tasks related to computer graphics and the skills to solve them. In order to enhance the fundamental component of computer graphics, methods are proposed that rely on interprandial communications, as well as on in-depth training of computer graphics. In the course of reasoning, the authors come to the conclusion that the content of computer graphics should be enriched with mathematical foundations of computer graphics and as a result update the content of the computer graphics course with machine graphics algorithms. The basic principle of selecting the content of the course offered is the principle of the fundamentalization of education. Since the scope of application of computer graphics is extensive, in our opinion, the system of tasks and tasks on computer graphics is the most interesting. A feature of this system is the orientation towards solving fundamental problems of computer graphics. It was also revealed during the study that it is possible to reduce the tasks of the proposed system to a certain sequence of stages. The application of stages for a certain type of tasks affects the methods of solving them. Thus, the fundamental training of future informatics teachers in computer graphics requires them to know these stages and methods of solving fundamental computer graphics tasks.

Desire To Change

Anger is a basic human emotion that has a force for constructive or destructive ends. Its expression in any circumstance can be a trigger for a desire to change a prevailing situation. In all cases, anger is a fundamental component of art. This study examines the use of anger in Osborne’s Look Back in Anger and Osofisan’s The Chattering and the Song. Osborne and Osofisan are two writers who are very anxious to change their societies through their art. In spite of differences in their origin (Osborne was a Briton while Osofisan is a Nigerian), they wrote at a time of certain social and political upheavals in their countries. They also share similar concerns and attitudes towards art. My focus in this paper is on the early plays of Osborne and Osofisan where anger is strongest and where their artistic triumph is most poignant. Working within the formalist approach, the paper reveals that in Osborne and Osofisan, extreme anger is both material and style and is what marks their art out. The reification by the intellect provides a potent instrument for investigating society. Anger becomes the point of departure for their art, it is not mere hysterics but a cerebral one and it is the motivating force for their writings.

Water Scarce

Hotels are a fundamental component within the tourist Spanish sector, and their role in water management turns out even more relevant taking into account the fact that tourist areas, in which they are generally located, are water scarce. Trying to go further from the standard ratios and estimations to plan water conservation, this work intends to really measure and quantify water use in rooms. Only by doing this, can subsequent conservation actions, now able to be reliably specified for each specific use, achieve a real success.
