THE INFLUENCE OF THE ARCHITECTURE OF MEDICAL INSTITUTIONS ON THE PSYCHOLOGICAL AND PHYSICAL CONDITION OF A PERSON

This article analyzes the factors of the influence of architecture of buildings of medical institutions on the state of human health. The main problems faced by the architect in the design of hospitals and the possibility of solving them are considered. One of the most important problems an architect faces when designing medical facilities is to create a free and open atmosphere. To restore health,not only the quality of medical services is of importance, but also the beauty and convenience of the rooms in which the treatment takes place. To achieve the effect of a healing architecture, designers must, first of all, establish a constructive dialogue with medical workers and patients. Ideas, models and sketches of the architect should be critically evaluated and discussed. The article identifies the main architectural factors contributing to the recovery of patients and creating a trustworthy, psychologically healthy environment. The term “healing architecture” and the relations of famous architects to it are considered. The emergence of a new term indicates the general need in our technogenic world to create an environment that would positively affect the health and psyche of visitors and patients of medical institutions. The purpose of healing architecture is defined. Experts agree that the future lies with clinics whose appearance will more likely resemble residential premises than a hospital in our traditional view. The functional planning structure is changing, because with the advent of the latest technologies, the requirements for certain rooms, their location in the building volume, dimensions, insolation, etc. have also changed. In addition, work is underway to improve the territories of medical institutions as nature also has a rehabilitative effect on people. The worldwide examples of the architecture of medical facilities that have a positive impact on human health are considered.

Stainless Steel Surface Nitriding in Open Atmosphere Cold Plasma: Improved Mechanical, Corrosion and Wear Resistance Properties

This work presents preliminary results regarding improving the mechanical, wear and protective properties (hardness, coefficient of friction, corrosion resistance) of AISI 304 stainless steel surfaces by open atmosphere cold plasma surface treatment method. Comparative evaluations of the morphological, corrosion resistance, mechanical and tribological properties for different periods of treatment (using N2 gas for cold plasma generation in an open atmosphere) were performed. AFM surface analyses have shown significant surface morphology modifications (average roughness, FWHM, surface skewness and kurtosis coefficient) of the treated samples. An improved corrosion resistance of the N2 treated surfaces in open atmosphere cold plasma could be observed using electrochemical corrosion tests. The mechanical tests have shown that the surface hardness (obtained by instrumented indentation) is higher for the 304 stainless steel samples than it is for the un-treated surface, and it decreases gradually for higher penetration depths. The kinetic coefficient of friction (obtained by ball-on-disk wear tests) is significantly lower for the treated samples and increases gradually to the value of the un-treated surface. The low friction regime length is dependent on the surface treatment period, with a longer cold plasma nitriding process leading to a significantly better wear behavior.

Multiple Reflow Influence over the FeCoCrAlTiCuNiMo Coating Obtained by Plasma Metallization on its Wear Resistance under Dry Friction

The article presents the research results of the plasma jet multiple reflow effect over the multicomponent coating FeCoCrAlTiCuNiMo, obtained by plasma metallization in an open atmosphere, on its wear resistance under dry sliding friction. The research results indirectly confirm the influence of the coating entropy over the wear resistance increasing along of the reflow number growth.
