No full textPředkládaná diplomová práce se věnuje analýze rizik a zhodnocení současného evakuačního plánu v průmyslovém podniku Weizel výroba elektrotechnických zařízení s. r. o. Jejím cílem je provést analýzu rizik a navrhnout nápravná opatření pro zajištění zvýšení bezpečnosti zaměstnanců a celého podniku. Součástí práce je zhodnocení evakuačního plánu pomocí simulace evakuace a cvičné zkoušky evakuace. Pomocí metody HAZOP byla provedena analýza rizik ve třech odvětvích zabezpečení podniku, bezpečnost zaměstnanců a výroba. Následným hodnocením byla zjištěna nejzávažnější kritická místa siréna, detekční čidla, kódování budovy, oplocení areálu, vstup do budovy a správce budovy, nepoužívání ochranných pracovních prostředků při práci, kouření na pracovišti, prach, lakovací kabina a práškové barvy. Byla pro ně navržena nápravná opatření, která by zajistila snížení míry rizika. Dále byla pomocí softwarového nástroje Pathfinder modelována simulace evakuace podle současného evakuačního plánu. V rámci provozní doby podniku byla provedena cvičná zkouška evakuace zaměstnanců. Modelace byla porovnána se cvičnou zkouškou evakuace. Na základě jejich komparace byla navržena optimalizace evakuace a byla taktéž navržena textová část evakuačního plánu.The thesis is dedicated to the risk analysis and evaluation of the current evacuation plan in the industrial company Weizel Výroba Elektrotechnických Zařízení s. r. o. Its aim is to carry out a risk analysis and propose corrective measures to ensure increased safety of employees and the whole company. The work includes the evaluation of the evacuation plan by means of a simulation of evacuation and a mock evacuation test. Using the HAZOP method, a risk analysis was performed in three sectors - enterprise security, employee safety and production. The subsequent assessment identified the most serious critical points - siren, detection sensors, building coding, site fencing, building entrance and building manager, non-use of protective work equipment at work, smoking in the workplace, dust, paint booth and powder paint. Remedial measures were proposed for these to ensure that the level of risk was reduced. Furthermore, an evacuation simulation was modeled using the Pathfinder software tool according to the current evacuation plan. A mock employee evacuation test was conducted during plant operating hours. The simulation was compared with the mock evacuation test. Based on their comparison, the optimization of the evacuation was proposed and the text part of the evacuation plan was also designed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The development of electrotechnical school in chomutov and the industrial development of Chomutov region
Get PDFThis bachelor work deals with evolution of secondary technical school in Chomutov according to industrial development and political situation in the region. The evolution of the school is compared not only with development of industry in Chomutov and its surrounding, but also with the political situation in the region. The political situation has influenced all industry and therefore the technical school. The evolution of the school since its foundation till nowadays is described in six stages. Every stage has relatively sharp borders that are set by the political situation in each time. The work shows that the technical school always has been the educational institution of highest qualities. The school has been able to flexibly react on technical development and recent needs of industry.Bakalářská práce se zabývá zachycením vývoje Střední průmyslové školy v Chomutově v souvislosti s průmyslovým rozvojem a politickou situací dané doby na Chomutovsku. Vývoj průmyslové školy je komparován nejen s rozvojem průmyslu v Chomutově a okolí, ale také s vývojem politickým. Právě vliv politického dění určoval směr vývoje nejen průmyslu, ale také průmyslové školy. Vlastní vývoj školy od jejího založení po současnost je v bakalářské práci rozdělen do šesti vývojových etap. Každá vývojová etapa má relativně ostré hranice, zejména díky politickým událostem daného období. Jak se v práci ukazuje, průmyslová škola byla vždy kvalitní vzdělávací institucí, která dokázala velmi rychle a pružně reagovat na technický rozvoj a aktuální potřeby průmyslu vybavením školy a efektivní změnou učebních plánů
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
