<abstract xmlns="http://www.w3.org/1999/xhtml">This article is a brief description of a new methodology1 for utilising the <italic>Nx – SCR CRABE SCUBA</italic> rebreather 2. This new approach differs from that described in a previous article [1,2]. The new methodology is based on a Polish theory3 mainly consisting of deterministic methods4 of modelling semi-closed circuit rebreathers. Further research5 can henceforth be carried out in a more reliable and efficient manner than ever before.</abstract>

Designing of diving technologies – process approach

<abstract xmlns="http://www.w3.org/1999/xhtml">The search and detection of objects under water is carried out by groups of specialised divers. However, their time underwater and their ability to penetrate the depths are limited. For these reasons, the use of unmanned underwater vehicles equipped with technical observation equipment, including TV cameras, is becoming increasingly popular for these tasks. Video images from cameras installed on vehicles are used to identify and classify underwater objects. The process of recognition and identification of objects is tedious and difficult and requires the analysis of numerous sequences of images, and so it is desirable to automate this process. In response to these needs, this article presents the concept of identification of underwater objects based on visual images from an underwater body of water sent from an unmanned underwater vehicle to a base vessel. The methods of initial processing of the observed images from an underwater area as well as the method of searching for selected objects in these images and their identification with the use of the Hough transform will be described. Furthermore, the paper presents the results of the preliminary processing and identification of the observed images following a deconvolution operation.</abstract>

On a method for supporting visual identification of underwater objects

<abstract xmlns="http://www.w3.org/1999/xhtml">This material is a continuation of the article published in the PHR no. 3(52)2015 concerning the methodology of selecting underwater exploration strategies for process development purposes. The article proposes to use one of the methods of decision optimization for the selection of the appropriate course of action in such cases.</abstract>

The optimisation of underwater exploration strategies which are to be implemented for process development purposes

<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of the article is a review of psychological literature relating to the problem of anxiety in divers, where an emphasis is placed on the degree of mental adaptation of the individual to the underwater environment, primarily highlighting the trait of anxiety and the neuroticism of a person involved in a specific type of diving. The article presents selected reports from all over the world regarding research on anxiety in divers. Treating a high level of the indicator of anxiety as a predictor of panic anxiety reveals the importance of this trait in predicting the risk of an occurrence of diving accidents during the operation under water. In the own research presented in the article, the results on the levels of anxiety as a trait and a state in divers taking part in hyperbaric exposures indicate the fact that the majority of the examined divers have low levels of anxiety both as a trait and a state, which most probably indicates the good psychological condition of the examined divers.</abstract>

Polish Hyperbaric Research

Why subscribe and read  In the journal one can find a wide range of original, high-value scientific articles from fields unpublished in other journals, which are hyperbaric technology and hyperbaric medicine. Through the publication of a broad base of results of research on major and related research fields of the magazine, Polish Hyperbaric Research provides an excellent platform for the exchange of ideas between scientists, experts and users of the technology. This is particularly valuable idea with the extremely scarce representation of magazines dealing with this issue in Europe (2) and around the world.  A multi Scientific Council representing both the main directions of scientific interest of the magazine and related fields, with affiliations in many countries of the world, whose members are employed in scientific centers, institutes and research centers guarantees a high level of knowledge, but above all an opportunity to present the results of multicenter multidisciplinary research.  The contents of each new issue of the magazine, in addition to original research papers is complemented by descriptions of cases and general outlook works -which is an excellent source of systematic knowledge for recipients - practitioners, students, etc.  The Polish Hyperbaric Research also publishes messages about events relevant to the research community.  Polish Hyperbaric Research is the journal owned and published by the Polish Hyperbaric Medicine and Technology Society.   Why submit  Our magazine prides itself on the fact that the priority of the Editorial Board is a quick and constructive process of reviewing and short deadlines between sending of the article, approval for publication and print. Editing is possible for both English-speaking and non-English speaking authors.  The degree of rejection of work of the mainstream topic, which the PHR is engaged in is not more than 25%.  The articles accepted for printing can contain colorful illustrations and charts as well as the publications of large volume, not accepted in most scientific journals.  Publication fee is 120 PLN per two pages A4, in special cases it is possible to skip the fee. Payment in PHR is charged only from authors after they'r article is alredy publicated. We dont charge fee for the act of processing the article. The amount of payment changes every year. The articles we order are free of charge.  In addition, PHR as the only Polish and one of the few scientific journals in the world gives annual award for science students for successful debut on the pages of the quarterly. This prize is awarded to the author who first published the material in a scientific journal which has achieved good marks in reviews.  It is an encouragement to further fruitful activity for young scientists, who begin their adventure with science. The prize is awarded annually by the decision of the members of the Editorial Committee and the Scientific Council in the form of a commemorative statuette and a promise of free publication of the following article. The award ceremony takes place during the inauguration of the annual scientific conference of the publisher i.e. Polish Society of Hyperbaric Medicine and Technology.  Archiving  Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.
