Výskyt porúch v stavebníctve, či už staršich alebo novších budov, môže mať viacero príčin, môže to byť spôsobené zlým návrhom, nesprávnou realizáciou, kvalitou použitého materiálu a tiež zanedbanou údržbou. Zvláštne problémy sú spojené s výskytom kolóniami baktérii, húb, plesní a iných mikroorganizmov, žijúcich na povrchu niektorých konštrukčných prvkov a častí objektov. Práca je zameraná na diagnostiku degradačných procesov, ktoré sa pozorovali na vybranom rodinnom dome. Biologické znehodnotenie stavebných materiálov a častí stavby je v dnešnej dobe veľmi aktuálny problém, pretože degradácia pr.rodných a syntetických stavebných materiálov je úplne prirodzený a nezvratný proces, v ktorom sa významne podieľajú nielen abiotické korozívne látky, ale aj vyššie uvedené faktory. Výber diagnostických postupov a metodík na posúdenia degradácie preto zohráva

The weights of evaluation criteria could have a significant impact on the results obtained by using multiple criteria decision-making methods, which is why a number of methods have been proposed for determining them. In this article, the use of a newly proposed method for determining criteria weights, the PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA) method, is presented in the case of determining weights of criteria for assessing the quality of e-learning materials. The main goal is to define which criteria are the most important and have the crucial influence on the quality of e-learning material, as well as to demonstrate the applicability of the proposed method and the simplicity of its application.

Full textAbstract:
Empirická studie pojednává o perspektivách využití metody eyetrackingu, založené na sledování očních pohybů při percepci verbálního a ikonického textu, a přináší výsledky předvýzkumu z roku 2014, jehož cílem bylo ověřit výzkumný nástroj pro zkoumání vlivu konkrétního způsobu strukturace analýzy historické karikatury na kvalitu její interpretace respondenty. V první kapitole jsou vymezena teoretická východiska (význam historických pramenů v procesu rozvíjení kompetencí historického myšlení) a jsou zde uvedeny možnosti uplatnění eyetrackingu v pedagogickém výzkumu. Ve druhé kapitole jsou popsány použité metody sběru a zpracování dat. Zvolen byl smíšený výzkumný přístup, zahrnující analýzu audiozáznamů slovních odpovědí studentů a statistických i vizualizovaných dat získaných elektronickým měřením. Testováno bylo 23 studentů učitelství z Moravskoslezského kraje. Ve třetí kapitole jsou prezentována výzkumná zjištění – návrh kategoriálního systému pro interpretaci karikatury, vizualizace dat v podobě heatmap, gaze opacity map a gaze plots a nejvýznamnější kvantitativní data (rozdíly v četnosti a délce očních fixací v průběhu testu). Předvýzkum ukázal, že eyetracking může poskytnout jinými metodami obtížně zjistitelné informace o percepčních strategiích uplatňovaných při interpretaci textu. Výsledky naznačují, že v případě didakticky strukturované analýzy historické karikatury dosahují respondenti vyšší úrovně interpretace než při analýze nestrukturované, kdy se slovní odpovědi omezují převážně na zobrazené osobnosti a jsou opomíjeny důležité symboly, obrazové kódy i širší historický kontext.

Full textAbstract:
I denne artikkelen stilles spørsmål om erfaringer av sårbarhet kan gis relevans i relasjon til profesjonsetisk kompetanse i lærerutdanning: Kan vi få fram troverdig kunnskap om betydningen av lærerutdannerens opplevde sårbarhet i undervisningssituasjonen? Hvilken betydning kan opplevd sårbarhet ha for lærerutdannerens profesjonsetiske kompetanse? Kan sårbarhet bli en kvalitet ved undervisning i lærerutdanning? I så fall hva er betingelsen for det? Undervisning om skapende dans i kroppsøvingslærerutdanning brukes som case, der en lærerutdanners metarefleksjon over egen undervisning brukes som materiale. Metarefleksjonene analyseres videre gjennom etiske og fenomenologiske begreper, som mellomkroppslig samspill og kroppslig resonans. Analysen får fram at det å tenke om sårbarhet som profesjonsetisk kompetanse kan være verdt å diskutere; herunder om sårbarhet og bearbeidelsen av dette kan være en ressurs for å skape gode relasjoner til studentene, inngå som en beredskap for å møte etiske valgsituasjoner, bidra til å handle moralsk i undervisingsøyeblikket, samt være en kilde til empati. Konklusjoner fra analysene er at det å vedkjenne seg og å bearbeide sårbarhet bør kunne gjøres relevant som bidrag inn i lærerutdannerens profesjonsetiske kompetanse og bli en kvalitet ved undervisning i lærerutdanning.

Full textAbstract:
V souladu se závěry zahraničních recenzentů (Acheson, 2017; Champ Morera, 2017; McGill, 2015) považujeme CAS2 za originální metodu, která je velice jednoduše administrovatelná a jež má kvalitně zpracované testové materiály. CAS2 oproti jiným dostupným testům kognitivních schopností nabízí ipsativní analýzu, tedy na statistice založenou identifikaci silných a slabých stránek probanda. Přes drobné nedostatky můžeme CAS2 doporučit s jistou opatrností k běžnému užívání, a to hlavně díky aktuálním českým normám vytvořeným na základě poměrně velkého standardizačního souboru. Je však nutné počítat s tím, že normy jsou pravděpodobně o něco „tvrdší“ v důsledku nižšího zastoupení rodičů respondentů s nižším vzděláním.

Introduction: Fractures of the proximal segment of the femur occurring most commonly in elderly patients are a serious, both medical (orthopaedic) and socioeconomic, problem. Material and Methods: 46 patients (14 male and 32 female) operated for hip fracture in the January-June 2008 period, who were available for analysis (as 24 patients were not) were investigated. In addition to descriptive analysis, general health status-quality of life was assessed by means of SF-36 questionnaire comprising eight groups of questions determining the physical, psychological and social status of the patients within the 0 to 100 (problem) points range.. Results: The findings were that the average patient age was 74 years (76.9 for male patients and 74.06 fro female ones). The values of all eight parameters were lower by up to 89% in comparison to the pre-injury values, but improved by as much as 50% after six months (for physical functioning and the role of physical functioning) or by 30% for the role of emotions. The values never return to their pre-injury levels. In foreign studies, the parameters are higher, especially post-treatment values for vitality and role of emotions. Conclusion: In patients treated for hip fractures, it is necessary to carry out an assessment of general, physical, mental and social functioning of the patient in addition to the assessment of their clinical and radiological findings, so as to get a more realistic insight in the status of the treated and operated patients. The SF-36 questionnaire is widely used in such investigations along with other questionnaires. It is also necessary to investigate the general health status-quality of life of the entire healthy population in our country.

Ecological conditions of the growing areas, growing practices as well as harvest and postharvest processing influence the yield and quality of chamomile. The aim of this research was to determine the influence of chamomile separation methods, as postharvest treatments, on the essential oil quality and content, with a view to improve current primary processing of this valuable medicinal plant. In order to explain the structure of laboratory data that would give deeper assessment of similarities among various samples of chamomile essential oil, PCA was employed. Tested results showed that separation of chamomile plant material, as postharvest and pre-drying treatment, had significant influence on the number of identified compounds in the chamomile essential oil. The highest content of individual essential oil compounds had chamomile flowers with short stems, especially a-bisabolol, chamazulene, Z-spiroether and E-b-famesene. In the essential oil obtained from chamomile flowers with long stems, content of a-bisabolol and chamazulene were significantly lower, while E-b-famesene and Z-spiroether contents were significantly higher. Furthermore, in the essential oil obtained from chamomile plant material without separation, the lowest content of abisabolol and Z-spiroether, and the highest content of E-b-farnesene were recorded. The correlation analysis was performed to investigate the likeness in the amounts of the active compounds of essential oil from differently processed chamomile samples. All these results indicate the importance of precise and controlled postharvest treatments, since it clearly affects the essential oil quality and content in the primary processing of this valuable medicinal plant.

Full textAbstract:
The presented dissertation thesis is focused on investigating the adhesive properties of façade cladding made of wood and wood-based materials in combination with flexible adhesion/assembly systems. The systems allow the implementation of effective construction joints and provide a solution with uniform stress distribution which allows the transfer of heavy loads, while simultaneously reducing the weight of the entire structure, which is also often connected with substantial cost reductions. Despite all that, little attention has been paid to this area so far. It is not a solution which is properly embodied in technical standards or in designers´, architects´ and contractors´ awarenesses. The aim of this dissertation is to characterise adhesive properties of selected façade cladding representatives made of wood and wood-based materials for the purposes of bonded joint application in a ventilated façade system. To define adhesion of façade joints, numerical and experimental methods are used, taking also various limit conditions into account. The main conclusion of the dissertation is the characterisation of basic parameters which influence adhesion, effectiveness and quality of façade glued joints. The secondary conclusion is the compilation of a simple methodical procedure for testing and implementing façade glued joints. The dissertation also makes a contribution by extending the current state of knowledge of façade adhesive joints.

Full textAbstract:
Sažetak: Građevni otpad i otpad od rušenja nastaje tijekom građenja, održavanja, rekonstrukcije i rušenja različitih vrsta građevina ili kao posljedica prirodnih nepogoda kao što je primjerice potres. Količine građevnog otpada mogu biti značajne i stoga je neophodno uspostaviti učinkoviti sustav upravljanja ovom vrstom otpada kako bi se smanjilo njegovo odlaganje, a povećala stopa recikliranja. Pojedine zemlje Europske unije imaju već dugu tradiciju učinkovitog gospodarenja građevnim otpadom dok druge još uvijek u potpunosti ne iskorištavaju potencijal građevnog otpada kao nove, vrijedne sirovine. Preduvjet povećanja stope recikliranja građevnog otpada je odvajanje na samom mjestu nastanka te omogućavanje dovoljnog broja lokacija za prikupljanje i njegovu daljnju obradu ili distribuciju prema krajnjem korisniku. U radu su prikazane vrste te mogućnosti uporabe građevnog otpada uvažavajući zahtjeve zakonske regulative te preporuke znanstvenih istraživanja. Abstract: Construction and demolition waste is generated during the construction, maintenance, reconstruction and demolition of various types of buildings or as a result of natural disasters such as earthquakes. The quantities of construction waste can be significant and it is therefore necessary to establish an effective management system for this type of waste in order to reduce its disposal and increase the recycling rate. Some countries in the European Union already have a long tradition of efficient construction waste management, while others have not yet fully exploited the potential of construction waste as a new, valuable raw material. A prerequisite for increasing the recycling rate of construction waste is separation at the place of origin and enabling a sufficient number of locations for collection and its further processing or distribution to the end user. The paper presents the types and possibilities of using construction waste, taking into account the requirements of legal regulations and the recommendations of scientific research.
