This article presents a description of the water cooling system in the pool of the "Kobuz" decompression chamber constituting a part of the DGKN-120 hyperbaric simulator used at the Department of Underwater Works Technologies of the Naval Academy in Gdynia.

The article presents the general construction of an underwater vehicle manipulator along with a discussion of the materials used in their construction. The types of drive systems used by the manipulator have been characterised, distinguishing their advantages and disadvantages. The functions of the manipulator are specified in relation to the activities performed by it. Moreover, the paper discusses the manipulator's degrees of freedom with the specification of the formula for their calculation. The basic types of end effectors are presented as well as an outline of the classification of manipulators in relation to the tasks carried out.

The most hazardous adverse reactions following hyaluronic acid injections in aesthetic medicine involve vascular complications, known as the Nicolau Syndrome. This article presents a vascular complication in the area of the upper part of the nasolabial fold following subcutaneous administration of 0.5 ml of hyaluronic acid. At the time of the injection, paling occurred, which was followed by livedo racemosa appearing an hour later. Upon the lapse of a week, an ulceration appeared. It was not until the tenth day after the hyaluronic acid injection that hyaluronidase was administered. After 15 hyperbaric oxygen exposures, the ulcer was completely healed

This paper presents a case report of a patient with a diagnosed complication of a sternum wound which was treated using hyperbaric oxygen, emphasizing the truism of the benefits of combined surgical therapy, antibiotic therapy and oxybarotherapy.

Hyperbaric oxygen toxicity studies were conducted on rabbits using the opsonic index determination.The study was conducted on 15 animals that had opsonin index examined prior to hyperbaric oxygen exposure. They were then subjected to an hourly exposure to hyperbaric oxygen with overpressure values of 1.8, 2.4 and 3.1 atm in groups of 5 animals. After the exposure, the opsonium index was re-examined upon the lapse of 1, 2 and 10 days. Parallelly, the morphological image of the blood was examined.There was a statistically significant increase in the index in the first two days after exposure, independent of the value of oxygen overpressure. On the 10th day, the index value approached the initial one.

This work is a preliminary pilot research aiming at defining the role of the Piechcin Diving Centre in the development of specialised tourism. Particular attention was paid to the various elements defining the quality of the services offered. The key aspects and reasons for which respondents visit the centre were also determined. Both the customer’s expectations of the organiser of this form of recreation were analysed, and research was made to help understand whether the time the customers spends at the centre facilitates a positive decision regarding the participation in diving trips in larger bodies of water, with particular consideration of the Baltic Sea. Different forms of cooperation between the centre and regional authorities in terms of promoting the region were also reviewed.
