This diploma thesis deals with bathing children, especially infants and toddlers, in indoor swimming pools. It focuses primarily on the potential health and hygiene risks of this activity. It is divided into theoretical and practical part. The theoretical part provides a deeper insight into the field of artificial swimming pools, is dedicated to current as well as first ever legislation, in more detail is dedicated to the hygienic requirements for swimming pools according to Decree no. 238/2011, as amended; describes the process of pool water treatment, provides an overview of possible types of disinfecting pool water treatment and comparison within the advantages and disadvantages, describes indicators of water quality and their importance, and mostly focuses on hygienic and health risks in connection with the visit of indoor pools. Gives examples from practice (epidemic), mentions the most common sources of pollution including the most common violations of visitors. The theme of hygienic and health risks is then divided according to the origin of risk to the microbiological part (dedicated to infectious agents), to chemical part (disinfection by products) and to the part of accident risks and risks associated with the water temperature. The thesis is also keenly interested in the views of experts for bathing children, especially infants and toddlers, in indoor artificial pools. Research in the practical part was made by a qualitative method using secondary data analysis (operational and guest regulations, operational logbooks for 2015, the results of laboratory analysis of pool water for the 2015, laws and decrees), participant observation and interviews. The research was conducted in indoor swimming pools in towns Jihlava and Prachatice, which run swimming courses for infants and toddlers as well as for older children. For research, I set the following goals: C1: To monitor the microbiological and the physical-chemical indicators of the pool water quality in relation to Decree no. 238/2011 Coll., as amended, in pre-selected artificial indoor pools during annual operation. C2: To focus on the health status of children (infants and toddlers) in swimming classes. C3: To find out the knowledge and attitudes of visitors (parents) and trainers in the field of hygiene principles for swimming in artificial pools and risks arising from them. Based on the targets I have set the following research questions: V1: Are the monitored microbiological and physico-chemical water quality limits exceeded, and if so, which and under what circumstances? V2: What health problems, if they occured, did infants and toddlers after regular visits of indoor pools have ? V3: Are these children suffering from allergic diseases, and if so, from what type? V4: What knowledge and attitudes do visitors (parents) and lecturers in the field of hygienic principles for swimming in artificial pools and potential risks have? This thesis may serve the general public to extend the knowledge in the field of bathing (not only the children) in artificial pools and to give a view on this subject from different perspectives, as well as operators of swimming pools as an information material.

A través de la transcripción, edición y estudio exhaustivo de los cuestionarios de visita pastoral de Tortosa de 1314, de Gerona de 1329, del sínodo de Tarragona de 1372, de Valencia de 1383-1388, de Tortosa de 1409, de Jaume Marquilles (Barcelona) de 1413-1414, del "llibre de la cadena" (Barcelona) de 1425 y de Zaragoza de 1435, se pone de manifiesto la existencia de unas mismas directrices reformadoras de la iglesia y de la religión católica en todas las diócesis de la provincia eclesiàstica Tarraconense y de los antiguos reinos de la Corona de Aragón desde la celebración del IV Concilio de Letrán (1215) hasta el inicio del Concilio de Trento (1545). La reforma se concreta en los siguientes puntos de forma paralela en todas las diócesis de la Tarraconense, aunque podemos distinguir dos períodos claramente diferenciados: a) Desde el concilio de Lérida de 1229 hasta la vigilia del Cisma de Occidente: el esfuerzo reformador se centró en la moralidad del clero y su misión pastoral, y en la moralidad personal y social de los laicos, las visitas se asemejan a procesos eclesiásticos; b) Desde los inicios del Cisma de Occidente hasta la vigilia del concilio de Trento: el esfuerzo reformador se centró en los aspectos jurídicos y económicos de los beneficios, en la formación teológica sacramental de los curados y, muy especialmente, en la visitatio rerum, con la finalidad de implantar una política de la decoración que dirigía y promovía el incipiente culto eucarístico propio de las devociones populares del momento que, en muchos aspectos, se avanzó a la reforma del Concilio de Trento. No obstante, entre estos dos períodos y el que se inicia con el concilio de Trento, hay más continuidades que rupturas. / Through transcription, edition and exhaustive study of pastoral visits questionnaires of Tortosa in 1314, of Girona in 1329, of the synod of Tarragona in 1372, of Valencia from 1383 until 1388, of Tortosa in 1409, of Jaume Marquilles (Barcelona) from 1413 until 1414, of the "Llibre de la cadena" (Barcelona) in 1425 and of Zaragoza in 1435, the existence of the same church reformation directions and of the Catholic religion in all the diocese of the ecclesiastical province of Tarragona and of the ancient Kingdoms of the Crown of Aragon from the celebration of the Ivth Council of Letran (1215) until the begining of the Council of Trento (1545) is stated. The reformation is produced in a parallel way in all the diocese of Tarragona, although we can single out two clearly distinctive periods: a) From the Lleida Council in 1229 until the vigil of the western schism: the reformation effort was centered in the morality of the clergy and their pastoral mission, and in the social and personal morality of the laymen, the visits are similar to ecclesiastical processes; b) From the initial times of the western schism until the vigil of the Trento Council: the reformation effort was centered in the legal and economic sides of the benefits, in the theological and sacramental education of the priests and especially in the "visitatio rerum" with the intention of stating a decoration policy that was ruling and was promoting the incipient eucharistic cult typical from the popular devotions of the times, and in many ways, it was put forward to the reform of the Trento Council. There is more continuity rather than breaking.
