Hucl, Václav ; Holá, Miroslava ; Čížek, Martin ; Řeřucha, Šimon ; Pham, Minh Tuan ; Pravdová, Lenka ; Lazar, Josef ; Číp, Ondřej
Semiconductor lasers are increasingly widespread in areas that have been so far dominated by He-Ne lasers. One of such areas is the length metrology, where He-Ne laser operating at 633nm wavelength is still a traditional source of coherent light for laser interferometers distance measuring. The advantages of semiconductor lasers compared with He-Ne laser are greater optical power and a significantly wider range of wavelength tuning without mode jumps. Another advantage is the possibility of frequency modulation of wavelength of the laser diode by directly changing the injection current. The benefits predetermine these laser diodes for the realization of dual-frequency laser sources for heterodyne interferometry. In this case, using a phase-locked loop technique the optical frequency of a laser diode is locked to the optical frequency of another laser diode with a certain frequency offset in the MHz order. In our contribution we present utilization of DBR laser diodes in implementing a dual-frequency laser source for laser interferometry with heterodyne detection.\n

This paper presents a contactless system for automatic and contactless gauge blocks calibration based on combination of laser interferometry and low-coherence interferometry. In the presented system, the contactless measurement of the absolute gauge block length is done as a single-step operation without any change in optical setup during the measurement. The optical setup is combined with compact gauge block changer with capacity 126 gauge blocks, which makes the resulting system fully automatic. \nThe paper also presents in detail a set of optimization steps which have been done in order to transform the original experimental setup into the automatic system which meets legal length metrology requirements. To prove the measurement traceability, we conducted a set of gauge block length measurement comparing data from the optimized system and the established reference system and TESA–UPC operated in Czech Metrology Institute laboratory.

General Data Protection Regulation and its Impact on Grey Literature
Koščík, Michal
In April 2016, the European commission adopted a new General Data Protection Regulation. This regulation is based on fundamental principles of the existing legislation and elaborates it further into the set of rather detailed legal instructions. The suggested paper aims to summarize the parts of the new regulation that are most relevant for operators of gray literature repositories, who will have to adapt within the next two years. The paper will focus on the issues of consent to the processing of personal data, the legal regime of processing personal data without the consent of the data subjects, the data subject’s right to information as well as the legal regime of acquisition of personal data by third parties and exercise of the newly formulated right to be forgotten.

From Radioart to Musical Theatre
Jiřička, Lukáš ; KLÍMA, Miloslav (advisor) ; NOVOTNÝ, Pavel (referee)
This dissertation From Radioart to Musical Theatre aims at showing connections between seemingly different fields ? mainly sound-drama radioart, which in German is called Hörspiel, and musical theatre. In my dissertation, I try to define the characteristics as well as structural principles of text, space, sound, voice, acting, music and body in these transdisciplinary forms and genres, which have never retained any kind of purity in the traditional sense.In the analytical and introductory historical part of my dissertation, various seemingly different areas were introduced and discussed. These areas were musical or sound theatre in its general as well as specific form and its interrelation with sound installations, performance, radioart in form of Hörspiel, musical composition and sound art. In the following chapters, I used examples of several pivotal personalities from the German speaking area skilled in musical composition as well as directing and dramatics to present for instance the influence of musical structure on composition and other performing activities or the relationship of dramatic or literary model to its scenographic adaptation. The whole issue of relationships of disparate art forms is being showed on the examples of several artists ? directing composers who create these links thanks to their activity in various fields, as they intertwine musical and performing worlds on the level of structure, motifs and dramatics. The creators of such heterogeneous artworks using the strategy of the so-called negative dramatics are inherently split personalities - Heiner Goebbels, Helmut Oehring, Olga Neuwirth and Andreas Ammer. Goebbels as well as Oehring, Neuwirth and Ammer are able to make use of their experience with musical composition and/or work for the radio in the creation of musical performances in the way that they let particular composition techniques and staging be freely influenced by the knowledge of other media. Besides the above mentioned group of artists, I mention also other significant authors from the 20th and 21st century, who dealt with radioart, musical composition, collage and montage, performance and musical theatre - Bertolt Brecht, Dziga Vertov, Emil František Burian, Walter Ruttmann, John Cage, Karlheinz Stockhausen, Dieter Schnebel, Georg Katzer, Friedrich Schenker, FM Einheit či Laurie Anderson and Georges Aperghis. Without the influence of the last fifty year-history of radioart, musical theatre would certainly not be such an important form of alternative theatre and performing art as such. Especially nowadays, when thanks to the emancipation and stressing of sound at the expense of acting a new stage language is being created within musical theatre, and the form itself transforms into yet little analysed field of the so-called postspectacular or mechanical theatre without actors.

Intraday trades
BOHINSKÝ, Petr
This thesis is focused on comparison of intraday and short term trades profitability using technical analyses by application the method of crossing moving averages between January 1st 2014 and August 1st 2016. Trading takes place on the basis of buying and selling signals of a generated technical indicator in the investment program Alapri and XTB. The traded indexes are DAX 30, S§P 100 and commodities gold and oil. The theoretical part of this work is devoted to the financial market, commodity market, describes intraday and positional trader and advantages as well as disadvantages of these markets. It also deals with technical analyses and explains basic investment terms. Practical part of the work is devoted to a description of the results modeled on real historical data. It is possible to determine on the base of back-tested results that the method of crossing moving average with the value of the instrument is better for short-term trades; in modeled example in daily graph than for intraday trades modeled in four-hour graph. Furthermore when modeling there was found that it is more profitable to buy instruments and let them be valorized by the financial market under given conditions. It means to buy them at the beginning of the investment period and sell at the end of this period without any buying and selling operations.

The role of nurses and their impact on the care of patients with total hip arthroplasty.
SLABÁKOVÁ, Květoslava
Total hip replacement is one of the most extensively and highly effective operating methods in orthopaedics. The patients are brought back the self-sufficiency, life without the pain and noticeably motion restriction. Irreplaceable function here is a role of the nurse, who helps the patient to return back to his common life...The aim of this work was to find out, how the patients feel the role of the nurse and its influence to given nursing care before and after the total hip replacement as the less fulfilled. There were following research questions set: How the patients feel the role of the nurse before and after the total hip replacement? How the patients before and after the total hip replacement feel the interpretation of the nurse roles? How the patients before and after the total hip replacement feel the role of the nurse and its influence to given nursing care. Which of the nurse roles are felt by the patient as the unsatisfactory in postoperative care? The patients before and after the total hip replacement feel through the everyday nurse activities the nurse in her role of the caregiver and education giving person, following the nurse vindicator and the nurse bearer of changes. The patients feel the care thanks these roles as a quality, holistic and continual. Nevertheless was the role of the education giving named as the least fulfilled. In connection with these research results was created a manual, a Guide book for the patients before and after the total hip replacement. This Guide book was given to testing purposes. This Guide book was appreciated by the patients very positive despite a large amount of information, which were surprising for many of them. We gained some data, which gave the impulse to complete the information in the Guide.The created Guide book can´t replace the effective communication of the patient with the medical staff, which could be always the most suitable "source" of information.

Coping strategies in children´s fear and pain in relation to nursing care
PROCHÁZKOVÁ, Zuzana
For the nurse, taking care of hospitalized children is important not only pediatric nursing knowledge, personal and social preconditions, but also the theoretical and practical competency of methods and techniques, which are used for identification and effective influencing of pain and fear. The aim of this thesis was to identify the main sources of fear of the hospitalized preschool and young school age children and to find out the effective methods and principles of the cooperation with children, alternatively with their accompanying parents in order to moderate the fear of the small patient. Then the thesis tried to chart the nursing diagnostic and evaluation procedure of the pain and get the most used nursing methods of non-pharmacological pain relief. To obtain the necessary data, the qualitative research was used with a semi-structured interview as a research instrument. The first research group consisted of 12 nurses, the second group consisted of 12 children ´s patients of preschool and young school age. The majority of the asked nurses thinks, that children´s patients are afraid especially of non-familiar environment, then of the awaited pain and of the solitude without parents. However, the most patients said, that they were afraid especially of pain, then of non-familiar environment, restriction of their needs, hostile attitude of the medical staff and of the other neighbouring patients. They were also frightened of the death and of the darkness. Most reported nurses mean, that the most effective solution of the children ´s fear is the friendly attitude of the medics. They also mentioned the fact of taking the focus off the fear and the presence of the parents is also beneficial. The nurses ´ answers were in conformity with patients opinion in two fields - friendly attitude of the medics and taking the focus off the fear. Then the children mentioned abiding of their specifics in connection to falling asleep and the demand of beying treated by the same sister or by few same sisters. All respondents also talked about the benefit of parents presence. Regarding the principles of the cooperation, nurses answered the importance of united medical procedures, especially the proper way of information transfer. Then the respondents nurses mentioned the psychical and emotional support for children and their accompaniments, the atmosphere of confidence and the value of well done education. Also the need of calm, silence and privacy was stated. Unlike nurses, children and their parents regarding to principles of the cooperation prefer the psychical and emotional support, then the importance of enough information was mentioned. The fourth research question bears on the methods used for children pain monitoring. The nurses said, that the intentional interview with the patients or with the parents was used as a main technique, that was stated by patients as well. Research question number five said: What are the most used nursing methods of non-pharmacological pain relief at children? Most responded nurses mentioned the distraction of children attention from the painful incentive, then the importance of physical methods, relief position and purposeful preparation for the unpleasant intervention. Nurses also named the helpful contribution of the parents, relaxing exercises and the method of imagination. Regarding the pain treatment, it was noted, that all patients prefered the analgesic therapy. Then they quoted the distraction of their attention from the painful incentive, the friendly attitude of the medics, using the ice compress and the relief position. In the pain acute phase, children required mostly calm, comfort and privacy. All children also considered the presence of parents as very helpful. The theoretical and empirical part of the thesis are suitable for being studied by nurses taking care of children and it can be helpful for nursing quality improvement at children ´s wards in hospitals.
