The idea of sustainable development did not appear in the eighteenth century for ecological reasons to save the environment or humanitarian reasons to save humanity, but for economic reasons to improve the management of forests and fossil resources. Its creator was Hans Carl v. Carlowitz (1645-1714), a Saxon tax accountant and mining administrator. The idea has always served an economic purpose – constant economic growth as well as increase of productivity and profit. Therefore, it worked best in the sphere of management. Over time, it turned out that one could achieve better economic effects. when one combines economic goals with those that people have always strived for – to create a better world, life and interpersonal relations. This requires care for the good condition of the natural and social environment. Consequently, the idea of sustainable development was coupled with the goals of ecology and sozology. Unfortunately, for various reasons, the modern world is less and less conducive to achieving these goals. Therefore, one can increasingly difficult implement the postulates of sustainable development, even in the sphere of economy. It has become clear that sustainable development is not a panacea for all the ills of the world. The idea of this unrealizable development turned into a myth and a tool to manipulate people's feelings and dreams of a better life. With their help, one mobilizes people to higher and higher productivity, which generates an increase in the enrichment of the financial elite and to the accompanying to it deepening of social inequalities, which are the source of all the evil.

Idea rozwoju zrównoważonego nie pojawiła się w XVIII wieku z przyczyn ekologicznych dla ratowania środowi-ska ani humanitarnych dla ratowania ludzkości, tylko z ekonomicznych dla poprawy gospodarowania lasami isu-rowcami kopalnymi. Jej twórcą był Hans Carl v. Carlowitz (1645-1714), saksoński księgowy podatkowy i za-rządca górniczy. Przez cały czas służyła celom ekonomicznym –nieustannemu wzrostowi gospodarczemu, wy-dajności i zysku. Dlatego najlepiej sprawdzała się przede wszystkim w sferze gospodarowania. Z czasem okazało się, że lepsze efekty ekonomiczne można osiągać wtedy, gdy cele ekonomiczne połączy się z takimi, do których ludzie zawsze zmierzali –do stworzenia lepszego świata, życia i relacji międzyludzkich. A to wymaga troski odobry stan środowiska przyrodniczego i społecznego. Wskutek tego idea rozwoju zrównoważonego sprzęgła się z celami ekologii i sozologii. Niestety, z różnych względów współczesny świat coraz mniej sprzyja realizacji tych celów. Dlatego coraz trudniej urzeczywistniać postulaty rozwoju zrównoważonego, nawet w sferze ekonomii. Przekonano się, że rozwój zrównoważony nie jest panaceum na wszystkie bolączki świata. Idea tego nierealizo-walnego rozwoju przekształciła się w mit i narzędzie manipulacji uczuciami i marzeniem ludzi o lepszym życiu. Za ich pomocą mobilizuje się ludzi do coraz wyższej produktywności, która generuje wzrost bogacenia się elit finansowych i towarzyszące mu pogłębianie nierówności społecznych będących źródłem wszelkiego zła.

The paper presents the results of studies of the influence of the quality of power systems on the characteristics of an asynchronous electric motor with a squirrel-cage rotor. During the research, a mathematical model of an induction motor, made in the MATLab software environment, was used. Based on the simulation results, the coefficients of the torque ripple and the phase current unbalance were determined. The results obtained are compared with previous studies of the manifestation of turn-to-turn closures in the phases of the motor stator winding, which also create an asymmetry of the rotating magnetic field.

W artykule przedstawiono wyniki badań wpływu jakości układów zasilających na charakterystyki silnika indukcyjnego ze zwartym wirnikiem. W badaniach wykorzystano model matematyczny silnika indukcyjnego wykonany w środowisku oprogramowania MATLab. Otrzymane wyniki porównuje się z wcześniejszymi badaniami występowania obwodów międzyzwojowych w fazach uzwojenia stojana silnika, które również tworzą asymetrię wirującego pola magnetycznego.

Identification of cervical metastatic lymph nodes (LN) on I-131 post-ablation whole-body planar scans (WBS) for cancer staging is crucial for patients with papillary thyroid cancer (PTC). The existing deep network is plagued by instability in finding the under-represented LN classes on highly complex WBS, where end-to-end tuned models that can account for this uncertainty region for multi-class locations are needed. Hence, as a key contribution of this study, we designed a novel leveraging segmentation network with input guidance (LSIG) end-to-end training model without pre and post-processing features that can learn ideal parameter settings depending on the quantity of multiple-object instances. To improve the co-occurrence of classes and control the false positive regions, we proposed a re-weighting negative control (RNC) mechanism that combines two key components, namely the re-weighting (Rw) term and the negative control function (NcF). This unified approximation of weighted training would leverage the network to control and learn the desired weights of true positives towards the LN region. As an end-to-end network training, we utilize a Unet-like convolution neural network (CNN) model. The performance of the LSIG is compared with the CNN-based networks, based on the ground truth (GT) mask developed using post-ablation single-photon emission computed tomography (SPECT/CT). Furthermore, the effectiveness of the two components used in the LSIG framework is evaluated on WBS datasets. Our proposed LSIG with a fully guided (Fg) LS-FgCNN model yielded a superior performance with high AUC value of 94.9%, which is 14.6% higher than the previous network for PTC.

The article is devoted to applying the concept of early detection of pathological crisis processes to analyze the dynamics of Ukrainian agriculture development in 2003-2011. The analysis is based on time series of the export, import, production volume, export and import prices for agricultural products, volume of loans and investments. Despite the fact that the only branch that demonstrated the growth of output in 2008-2009 was agriculture, there were observed four years of crisis in agriculture during the period under consideration. The built signal panel and structural and logical model of pathological crisis processes detection in agriculture of Ukraine showed that the leading role was played by the investment balance deficit, reduction of the technological level of exports compared to imports and growth of domestic production credit bubble.
