{"title":"The Propensity to Risky Behaviour and Subjective Risk Assessment Among Selected Groups of Divers","authors":"W. Wiesner, P. Siermontowski, I. Pawelec","doi":"10.2478/phr-2021-0004","DOIUrl":"https://doi.org/10.2478/phr-2021-0004","url":null,"abstract":"Abstract In this study, it was assumed that the propensity to risk behavior is a relatively persistent feature of an individual’s behavior. A person prone to risk, having the choice of taking a risky or cautious behavior, usually chooses to choose a risky behavior. The level of propensity to risk is related to the perception of the size of the threat and the motivational tendency to risk behavior. Risk management, and therefore managing your own safety, is a skill that is particularly important among people who undertake activities with a high level of risk. These include all underwater activities. The aim of the research was to find an answer to the question of whether there is a relationship between the level of risk behavior and the subjectively assessed risk in diving? Also, are there differences between different groups of divers in terms of risk behavior? 112 divers from public services (military formations, police, PSP) participated in the study, of which the results of 67 people were finally analyzed. The Ryszard Student’s Risk Behavior Test, the Makarowski Risk Acceptance Scale and the proprietary subjective risk assessment questionnaire were used. It has been shown that among all professional groups of divers, the group of policemen is more prone to risky behaviors than the other groups. No other dependencies have been confirmed.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"74 1","pages":"43 - 60"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49382757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deltamethrin’s action is characterised by nephrotoxicity, hepatotoxicity and immunotoxicity. The aim of the study was to evaluate the effect of poisoning with deltamethrin on the levels of interleukin1ß and TNFα in the livers and kidneys of mice. A total of 24 female mice were divided into 3 groups of 8: - controls, - receiving deltamethrin i.p. at the dose of 41.5 mg/kg for 28 days - receiving deltamethrin i.p. at the dose of 8.3 mg/kg for 28 days. On day 29 the animals were euthanised, livers and kidneys were obtained, homogenised and centrifuged. The supernatant was used for measuring IL-1ß and TNFα concentration with ELISA tests. The results were analysed with Statsoft Statistica. The interleukin 1ß concentrations were significantly higher in the kidneys (18.30±16.85) of mice exposed to the higher dose of deltamethrin than in the controls (8.15±4.66) (p<0.05). In the livers of mice receiving 41.5mg/kg deltamethrin it was 203±71.63 vs 46.77±34.79 (p<0.05). In the livers of animals receiving the lower dose it was higher than in the control group (96.51±24.73) (p<0.05). The TNF α was elevated in the kidneys of mice exposed to the higher dose of deltamethrin (6.56±3.26 vs 2.89±1.57)(p<0.05). Conclusion: Deltamethrin produces a significant increase of interleukin 1ß in the livers and kidneys of mice and so the cytokine seems to be a good marker of hepatotoxicity and nephrotoxicity in the course of subacute poisoning.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"74 1","pages":"61 - 66"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46217517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Olszański","doi":"10.2478/phr-2021-0019","DOIUrl":"https://doi.org/10.2478/phr-2021-0019","url":null,"abstract":"Abstract Here we present a unique life path of Sergiy Gulyar, a world-known Ukrainian scientist who was overcoming extreme conditions studying them on himself. He has developed his determination and responsibility from his basic experiences as a surgeon and his desire to win from his involvement in sports. His research in underwater laboratories has shown a capacity to find untrodden pathways to understand and explain what others did not even suspect. His physiological studies on the role of sea depths, breathing mixtures, underwater exposures, and diving schemes marked the path to the aquanauts and undersea man. Reaching the hyper depths equivalent to 2,500 m revealed the physiological limits of human being and defined how to handle hyperbaric respiratory failure. Prof. S. Gulyar suggested a usage of natural physiological mechanisms to accelerate the re-adaptation process as a part of the high-mountain rehabilitation of hyperbaria-adapted people. Dissertations were defended, books and articles were written, a scientific school of followers was created. Unfortunately, during the Soviet period, Prof. S. Gulyar faced a set of organizational problems and obstacles from the Soviet regime. In particular, his works were classified or hushed up, his intellectual property was often used without mentioning the author and his scientific team was intimidated by criminal investigations. Main recognition during this period had come from professional societies in Europe and the United States. After the collapse of the Union of Soviet Socialist Republics (USSR), Prof. S. Gulyar introduced a number of innovations and inventions in electromagnetic medicine and physiology. In particular, he has managed to account for main common features of physiological effects of light stimulation produced by Lasers, Light-Emitted Diodes and Bioptron light sources. By doing so, some mystical dogmas were filtered out and new paths to sensible light-induced treatments were developed. At the same time, Prof. S. Gulyar has preserved the legacy of many generations of medical professionals who used light in their treatments. He has shown in his physiological experiments that stimulation of biologically active zones including acupuncture points light stimulation has a wide spectrum of biological effects including alleviation of pain symptoms. Now mono- and polychromatic visual and transcutaneous light therapy of pain has been recognized scientifically and clinically, and its place in medicine has been firmly established. Prof. S. Gulyar described a new functional system of the organism that regulates the electromagnetic equilibrium. A step into the future was the first experimentally grounded technology for the use of fullerene-modified light. Positive changes have been proven with its percutaneous and ocular use. These first results open the door to complete analysis and future investigations. Prof. S. Gulyar has published 20 monographs, 470 papers and abstracts, and received 11 paten","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"77 1","pages":"7 - 38"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45101410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nieradko-Iwanicka","doi":"10.2478/phr-2021-0024","DOIUrl":"https://doi.org/10.2478/phr-2021-0024","url":null,"abstract":"Abstract Disability is an interdisciplinary-medical, social and professional phenomenon. The goal of medical professionals is to treat a person and restore his or her fitness. The group of disabled people in Poland is characterized by a lower level of education than among non-disabled people and high unemployment. The purpose of vocational rehabilitation is to make it easier for a disabled person to obtain and maintain appropriate employment and career advancement. Social rehabilitation is defined as an activity aimed at enabling a disabled person to fully participate in social life. The tasks of the local government addressed to disabled people include conducting occupational therapy workshops (WTZ), occupational activity establishments (ZAZ), community self-help homes (ŚDS) and social welfare homes (DPS). The aim of the study was to analyze the implementation of self-government tasks in the field of social and vocational rehabilitation of disabled people, with particular emphasis on ZAZ in the Lubelskie Voivodeship in 2008-2017. The work uses data collected in 2008-2017 by the Regional Center for Social Policy (ROPS) in Lublin. In addition, in December 2017, they were sent by e-mail to ROPS and Marshal’s Offices in voivodship cities in Poland, inquiries about tasks and ways of implementing these tasks in the field of social and vocational rehabilitation of disabled people in 2008-2017. The available data on expenditure from the State Fund for Rehabilitation of the Disabled (PFRON) was collected. The research material was statistically developed using the IBM SPSS Statistics (v. 25) and Statistica (v. 13) statistical packages. In the years 2008-2017 in the Lubelskie Voivodeship, PLN 75,529,959 was allocated for vocational and social rehabilitation of people with disabilities, the most (PLN 9,158,243) in 2016. In the same year, the largest number of people used the ZAZ. In 2008-2017, the average annual amount of expenditure on social and vocational rehabilitation of disabled people in all Polish provinces was PLN 7 576 718.9. In the discussed period, the highest amounts from PFRON were allocated to the rehabilitation of disabled people in the Śląskie Voivodeship, and the lowest in Lubuskie, while Lubelskie received average amounts. In Poland, in the field of social and vocational rehabilitation and employment of disabled people, solutions similar to those already developed are applied in the countries of Western Europe. The costs of financing vocational rehabilitation, understood as financing the functioning of the ZAZ by voivodship self-governments, are constantly growing. The growing expenses incurred on the activities of the ZAZ do not significantly improve the situation related to vocational rehabilitation and employment of disabled people. Improving the operation of the system of vocational and social rehabilitation of people with disabilities should not only consist in increasing the funds spent under the current inefficient system, but sho","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"77 1","pages":"89 - 102"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44952168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Absorption of light by ocean water limits the range light can travel before being extinguished. The complex interactions of scattering light and ocean water often lead to distortions of the signal as it propagates which degrades the quality and accuracy of underwater measurements. Consequently, underwater visibility (i.e. how well an object can be seen with definition at distance) can be less than 1 [m] in turbid and murky environments such as harbors. Advancements in laser imaging systems make highly accurate measurements at further ranges than has previously been possible through temporally filtering of a modulated laser signal at frequencies as high as 1 [GHz].

Oxygen therapy treatments are conducted in hyperbaric chambers, in which patients breathe pure, 100% oxygen with higher than atmospheric pressure. This allows to increase the amount of oxygen supplied to all cells of the body many times over. The treatment with hyperbaric oxygen therapy enables the patient to recover faster and be fully active, and also reduces the costs of standard treatment. The aim of the study was to summarize the possible applications of hyperbaric oxygen therapy. The available literature in the PUBMED database was reviewed in September 2022 with the use of the phrases ‘hyperbaric oxygen therapy’, ‘therapeutic applications’. The indications for therapy in a hyperbaric chamber are all kinds of diseases, both acute and chronic. The method supports the nourishment and regeneration of cells and tissues of the organism, and also slows down the aging process. However, due to the possible side effects of such therapy, patients should be qualified for its use after a careful analysis of their clinical condition and coexisting diseases. To sum up: hyperbaric oxygen therapy is most often used in the treatment of skin diseases and injuries, burns, and peripheral vascular diseases.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"77 1","pages":"73 - 84"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43973457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
