Opis: Webinar “Tools supporting academic integrity” with presentations on: Experiences in Establishing National Plagiarism Detection Systems Academic Integrity and Plagiarism on Slovenian Academic Institutions (Ojsteršek Milan) The Slovenian open access infrastructure consists of Slovenian universities repositories, a repository for research organisations, a repository for standalone faculties and a national portal (http://openscience.si/) that aggregates content from the repositories and other Slovenian archives (dLib.si, videolectures.NET, digital library of Ministry of Defence, Social Science data archive, ScieVie repository…). The national portal provides a common search engine, recommendation of similar publications, and similar text detection. During the setting up of the national open access infrastructure, the rules and processes for mandatory submissions of electronic theses, dissertations, research publications and research data were defined. One of the features is the use of software for plagiarism detection during the process of submitting electronic theses, dissertations and research publications. Technical characteristics of the plagiarism detection system used in the Slovenian national open access infrastructure will be presented. We will also describe established processes for awareness, prevention and detection of plagiarised documents. Finally, we will present chronologically organised data about the similarity of documents from the test corpus of documents, published on the internet after the year 2000. Nationwide Barrier to Plagiarism is Bearing Fruit (Kravjar Július) Plagiarism is a phenomenon that existed in the past, exists today and will exist in the future. Slovakia with its population of 5.4 million is confronted with plagiarism like other countries. The dynamics of changes in higher education, in ICT and internet penetration while at the same time a low level of ethics, copyright and intellectual property rights awareness in our country, contributed to the spread of plagiarism – an unwanted kind of “creativity“ after the year of revolutionary changes (1989). And there was an inherent lack of systemic action to create a barrier for future growth of plagiarism. The absence of a broader discussion of academic ethics (AE) had its consequences: the members of the academic community and the general public do not fully understood the importance of AE, hence they were less sensitive to the violations of AE. There were 13 higher education institutions (HEIs) in Slovakia in 1989, the number has now grown to 39, the number of students increased from 63 thousand to about a quarter of million and the teaching staff growth was insignificant. In 2008 MinEdu decided to acquire a plagiarism detection system (PDS) and create a central repository of theses and dissertations (CR) for all Slovak HEIs. It was the milestone for the nationwide CR and for PDS – both systems are known under the name SK ANTIPLAG. The preparation of the legislative environment (the amendment to the Higher Education Act, 2009) represented the fundamental prerequisite for the breakthrough in the fight against plagiarism and created an important step towards the implementation of the CR and PDS. The use of SK ANTIPLAG has been mandatory for all Slovak HEIs operating under Slovak legislation since April 2010. It is an example of an unparalleled and unprecedented implementation of such a system on a national level on a worldwide scale. Educational Resources for Plagiarism Prevention. Practical Work with Examples (Trevisiol Oliver) The participants will get to know, test, and review educational resources for plagiarism prevention. Examples are: - Exercises and tasks for courses (How, with which methods and conceptual formulation can I teach students about referencing and good scientific practice?); - Reviewed educational videos (Which video may I use in class?); - Examples of myths and rumours about plagiarism (Which questions and perception do students have? How can I react to typical notions and answer frequent questions?), such as the strange rule of “you need to cite more than 3 words in a row”.

Opis: The problem of determining the critical path for the scheduling tasks has been considered. An original technique for practical calculations using the available Solver add-on in Excel has been described. The proposed approach is based on reducing the task to solving the ordinary transportation problem, in particular to the problem of finding the longest path. Examples of solutions with the test input data and corresponding screenshots are given. The practical steps of the user’s action in the process of direct solution in Excel are consistently described. The analysis of the results of the proposed method has been performed and presented. It is established that presented method for calculating the critical path requires minimal efforts from the users, regardless of the dimension of the tasks.

Opis: Currently, the implementation of information and communication technologies (ICT) has been strongly recommended to science teachers. For identification the factors of successful ICT implementation the Unified Theory of Use and Acceptance of Technology (UTAUT) is applied, which works as the theoretical background of planned monitoring of Czech chemistry teachers´ attitudes to this problem. This theoretical review introduces the process of creating the modified UTAUT model serving as the basis for a research tool to be exploited for the future survey. Within this process three sources were exploited: (1) theories dealing with factors which influence user behaviour in relation to the use of modern technologies, (2) the analysis of research results focused on the acceptance and use of ICT in chemistry instruction and (3) results of researches conducted by the authors in the field of the effectiveness of the educational software used in chemistry teaching and learning. The conducted analysis of these three sources resulted in defining the presented survey and designing the appropriate theoretical model and research tool.

Opis: Modern design of the machine tool treats the suspending parts as a crucial element of the effective vibration isolation. Therefore the suspending items are specifically developed and subjected to extensive tests before being applied on real objects. These elements ensure accurate levelling and appropriate vibration damping. Usually selection of inadequate support element causes intensive disturbing effects in machining. The paper presents dynamics analysis of the machine tool suspended on flexible mountings. The overall analysis is conceived on a rigid body dynamics. This method enables selection of an optimal supporting configuration. Further on such an effective suspension design prevents a need for expensive monitoring of the dynamic characteristics of the mechanical system, i.e. machine tool and supports. The paper explores dynamics of a real, flexibly supported machine tool. Results are obtained with the assistance of the "SUPPORT" software. Finally the theoretical and computational statements are approved throughout extensive site measurements on the machine tool body with appropriate instrumentation.
