Mieczysław Wallis (1895–1975) authored 18 books, including 15 monographs in art history, the major ones being Autoportret (Self–Portrait, 1964), Późna twórczość wielkich artystów (The Late Works of Great Artists, 1975) and Secesja (Art Nouveau, 1967). Also worth noting is Sztuki i znaki. Pisma semiotyczne (Arts and Signs. Semiotic Writings, 1983).The main contribution of M. Wallis to art history lies in his modern metahistorical reflections, which are based on the firmly held beliefs about close relations between art history and other fields of art and aesthetics. His recommended method is moderate historiosophical relativism. We cannot avoid viewing the art of the past through the present. Changeable evaluations are the consequence of this, as is the relativization of the concepts and findings of art history. Wallis recognizes within the process of reception the important role that scientific discourse and cultural paradigm play. In Secesja he used the iconological method, combining art with the philosophical and scientific thought of the Belle Epoque. In his analyses of medieval art he introduced the semiotic method, having successfully avoided the constraints characteristic of semiological studies. His original remarks on the stylization of his appearance by means of dress show that the monograph Autoportret is still relevant to discussions on the theatricalization of reality. A philosophy of art history which assumes the variability of forms, of aesthetic sensibility and of knowledge does not necessarily lead to an extreme relativism, but accepts artistic pluralism; it allows us to retain the view on the continuity of art towards the avant–garde. Wallis interpreted its variable character by distinguishing between soft and sharp aesthetic values. Wallis laid the basis for an original, interdisciplinary approach to art. However, the distance that separated him from the aesthetics focused on the work of art itself, as well as from the social history and ideological criticism w hich were opposed to it, was the reason for his ideas to remain outside the mainstream of academic art history and aesthetics. Wallis contribution to art history is proportional to the role that he ascribed to this discipline among the various studies on art.
The transitional siliceous rocks from the Belchatow lignite deposit belong to the deposits with heterogeneous petrographic composition. The research allows us to identify among others, opoka-rocks and gaizes. The mineralogical-chemical analysis proves that the main ingredients of the studied rocks commonly used as building material are minerals of the SiO₂ group. Laboratory tests show that the nature of siliceous mineral phases has several effects on the geomechanical parameters of the studied transitional rocks. They are a reduction in water content and rock porosity, which leads to the transition of opal type A to opal type crystobalit and trydymit and then to quartz or microquartz. Their density and strength parameters are increased.
The paper deals with dynamics of present morphologic processes and cover deposits of nival and subnival stages in the area to the north of the Hornsund Fiord. Qualitative and quantitative parameters of the processes are described on the basis of direct measurements and radiocarbon datings. A particular attention was paid to the action of frost and gravitational processes in the specific morphoclimatic conditions of a nival landscape stage. The cover deposits are described from the point of view of their origin and physico-chemical properties. The age of the covers is defined on the ground of radiocarbon datings of fossil plants found at the nunataks for the first time in 1973. These datings enabled to distinguish the development phases of the morphogenetic processes during Late Holocene.
Telemedicine is one of the most innovative and promising applications of technology in contemporary medicine. Telemedical systems, a sort of distributed measurement systems, are used for continuous or periodic monitoring of human vital signals in the environment of living. This approach has several advantages in comparison to traditional medical care: e.g. patients experience fewer hospitalizations, emergency room visits, lost time from work, the costs of treatment are reduced, and the quality of life is improved. Currently, chronic respiratory diseases comprise one of the most serious public health problems. Simultaneously patients suffering from these diseases are well suitable for home monitoring. This paper describes the design and technical realization of a telemedical system that has been developed as a platform suitable for monitoring patients with chronic pulmonary diseases and fitted to Polish conditions. The paper focuses on the system's architecture, included medical tests, adopted hardware and software, and preliminary internal evaluation. The performed tests demonstrated good overall performance of the system. At present further work goes on to put it into practice.
