Social economy entities as organizational elements of economic civil society in Poland

100%

Kaczocha W. , Sikora J.

tom z. 168

177--185

Purpose: The article is intended to present the theoretical concept of the organisation of economic civil society shaped by social economy entities. Design/methodology/approach: Critical analysis methods used in literature studies; analysis of secondary documents such as legal acts, and official institutional documents. Findings: First, the article presents the theoretical concept of civic society, the conditions and reasons for its emergence, and describes its four forms. One of these forms consists of the emerging organisation of economic civil society. Such a society is based on the activity of social enterprises as social economy entities. We also stressed the need for cooperation between public administration units and social enterprises. Originality/value: The novelty of this article consists in outlining the concept of economic civil society. We also point-ed out that examples of the activities of social economy entities that organise economic civil society delineate the object of interest of the social economy. It takes into account social, economic, and environmental interests. We emphasised that this is the direction towards which economics, as a scientific discipline, should head. It should be heterogeneous and holistic.

Effective algorithm for tomography imaging in threedimensional problems

tom R. 95, nr 3

115--118

This article presents a new effective imaging method that can be applied in ultrasonic and radio tomography. The proposed method by changing the shape of the voxels leads to a substantial simplification of the algorithm at the cost of small approximations of the voxels. As proved in the work, these approximations do not have a significant impact on the readability of the image which is several times faster.

W pracy przedstawiono nową efektywną metodę obrazowania, która może mieć zastosowanie w transmisyjnej tomografii ultradźwiękowej lub radiowej. Proponowana metoda zmienia kształt voksela z sześciennego na kulisty dzięki czemu uzyskuje się znaczące uproszczenie algorytmu kosztem niewielkiej aproksymacji wokseli. Jak udowodniono w pracy, przyjęta aproksymacja nie ma znaczącego wpływu na wiarygodność obrazów, a jest kilkukrotnie bardziej efektywna.
