PROBLEMATIKA BEZPEČNOSTI V ZAŘÍZENÍCH URČENÝCH PRO VODNÍ REKREAČNÍ AKTIVITY / QUESTIONS OF SAFETY IN THE INSTITUTIONS INTENDED FOR WATER HOLIDAY ACTIVITIES

KADLECOVÁ, Jana January 2009 (has links)
``Water-related injuries{\crqq} are the second most frequent cause of death of children in the Czech Republic. My thesis addresses the issue of safety in facilities designed for aquatic leisure activities. Within the scope of the qualitative research with the aim to analyze technical standards, to ascertain their observance and afterwards to analyze the injury risks I used the data collection technique consisting in secondary data analysis, observation in combination with photographic documentation and semi-standardized interviews. For the research I selected a swimming pool in České Budějovice and Aquaviva Wellness Centre in Aurora Třeboň spa. The reason for this selection was creation of a pilot study monitoring safety in these facilities in South Bohemia. The Czech Republic has technical standards in place that are applied to minimize the risk of injury to the largest possible extent in facilities like that. They determine the procedures that have to be observed during construction and subsequent operation of facilities designed for aquatic leisure activities. The provisions defined by the standards are observed in both facilities but in their substance they are so generalized that it is only at the operators{\crq} discretion to what extent the safety is to be secured by them. They should be more specified and applied concretely to individual units of the equipment in order to create a safe environment. As far as risk places in the facilities are concerned, it may be stated that, regardless of compliance with the requirements defined by the standard, there is a large number of risks related in particular with slippery surfaces. Within the scope of the safety evaluation, it is also necessary to take account of hazardous behaviour of users of the chutes. The results of the research indicate that in Aquaviva Wellness Centre in Třeboň safety is secured and complies with the requirements of technical standards and the prevention requirements; the swimming pool in České Budějovice shows more serious defects {--} the standards are complied with but the surfaces are not covered with materials that would secure safety. On the basis of my research and other technical studies that confirmed seriousness of water-related injuries it is obvious that the issue of injuries in this field will require modification of safety measures and more precise specification of standards and thus elements such as materials of surfaces that would secure the required safety.

Undersökning av riktigheten för värmekonduktiviteter i ett vattenrutschbaneelement / Investigation of the propriety thermal conductivity for a water slide element

Olsson, Erik, Högberg, Fanny January 2022 (has links)
Den här studien handlar om att undersöka värmemotståndet för ett vattenrutschbaneelement för att se om det finns en skillnad mellan schablonmässiga och uppmätta värden för värmekonduktiviteten hos materialen men även undersöka hur stor påverkan de längsgåendeflänsarna har på transmissionsförlusten. Det finns ofta en skillnad mellan det schablonmässiga och faktiska värden när matningar genomförs på färdigställda konstruktioner. Syftet med studien är att undersöka riktigheten av schablonmässigt bestämt värmemotståndet för ett vattenrutschbaneelement (banmodell typ-1000) som produceras av Hydro Sport AB. Studien kommer även att undersöka materialens temperaturberoende utifrån värmekonduktivitet. En laboratoriemätning utfördes i ett klimatkammarskåp med värmeflödesmätare och termoelement för att bestämma värmekonduktiviteten för glasfiberlaminatet (GFRP) och mäta värmemotståndet för den sammansatta konstruktionen och genom att subtrahera glasfiberlaminatet värmemotstånd för att erhålla värmekonduktiviteten för Armaflex isoleringen. De framtagna värmekonduktiviteterna användes som parametrar i Comsol Multiphysics simuleringarna för att undersöka hur stor skillnad schablonmässiga och uppmätta värden har för denna specifika vattenrutschbana. Handberäkningar gjordes för att säkerställa att Comsol Multiphysics simuleringarna var pålitliga. Resultaten som framtagits i studien visar på att båda materialen men framför allt glasfiberlaminatet hade ett lägre värmekonduktivitetsvärde än det schablonmässiga som används i beräkningar i dagsläget. / This study is about examining the thermal resistance of a water slide element to see if it’s a difference between standard values and measured values for the materials thermal conductivity and also see how big an impact the horizontal flanges have for the heat balance of the structure. There is often a difference between the theoretical and actual values that is measured when the construction is finished.The purpose of this study is to validate the accuracy of the thermal resistance of a water slide element (track model typ-1000) that is produced by Hydro Sport AB. This study also covers thermal conductivity temperature dependent for the materials. A laboratory measurement was performed in a climate chamber with heat flux meters and thermocouples to obtain the thermal conductivity for the glass fibre reinforced polymer (GFRP) and measure the heat resistance for the whole composite construction and from there substract the GFRP heat resistance to obtain the thermal conductivity for the Armaflex insulation. The obtained thermal conductivity was used as parameters for the simulations in Comsol Multiphysics to investigate how big the impacts are between standard values and measured for this particular water slide type. To make sure that the Comsol Multiphysics simulations were trustworthy a hand calculation was made for this purpose.The results in this study revealed that both materials but especially GFRP had a better thermal conductivity than the standard value that is used today.

Centrum pro sport a volný čas Brno / Sports and Leisure Centre Brno

Chovanečková, Nikol January 2017 (has links)
The theme of the dissertation titled the Centre of Sport and Leisure Time in Brno is a design of a relaxing and sport site „Centrum Lužánky“. The subject of this project is architectonic-city-planning study, which deals with elaborating a concept of a sport centre behind Lužánky in Brno-Ponava. This dissertation contains details of the facility and the area of the current swimming pool Lužánky. The current state of the facility built in 1979 doesn’t meet requirements of visitors and sportsmen anymore. The main aim of this project is the reconstruction of the current fifty-meter swimming pool, a design of a new swimming pool placed under the ground floor of the current building, which will provide space for organizing international competitions, trainings of professional sportsmen, etc. At the same time the busyness of the current swimming pools would be lowered by building a new indoor and outdoor waterpark, especially for the group of recreational visitors. The attractiveness of the facility will be increased by the newly designed park relaxing area and proposed multipurpose area, used as a sports field in the summer and as an ice ring in the winter. Additional value of the facility is comprised by an indoor and outdoor café and large relaxing area on the roof of the waterpark. The whole area increases the community facility availability by a proposed wide range of services for health, relax and sport. The advantage of the whole concept is the mutual connection of all facilities. The entrance to the area is shortened by a designed pedestrian bridge, accessible from the south and north busy areas. The whole project is enhanced by increased number of new parking places, located particularly along the access road, the street Sportovní, going through a green zone. The road and parking places are proposed in the design of residential streets, respecting walking pedestrians. The area has a very rich sport history, which is dated back to 1922. The new concept increases th
