Astronomické informace pro profesionály jsou v dnešní době bez problému dostupné v odborných časopisech, databázích naměřených dat, knihách a internetových publikacích. Kde však může získat kvalitní nezkreslené informace širší veřejnost? Televizních astronomických pořadů je jako šafránu, a ty, které zbyly, jsou mnohdy kombinovány s astrologií, věštectvím a jinými pavědami. V rozhlase zůstaly pořady Meteor a Planetárium, ale ty se netýkají jen astronomie. Z ryze astronomických vědecko-populárních časopisů nám zbyl už jediný - Astropis - a doufejme, že přežije i nadále. Většina lidí se proto obrací k internetu. Pro laika je někdy obtížné odlišit kvalitní informace od balastu, a proto přinášíme čtenářům stručný výběr některých webů s hodnotnými astronomickými informacemi. and Petr Kulhánek.
This article deals with the issues of introducing web resources into subject literary bibliographies. This issue is at first analyzed on the general level as the methodological challenge of online sources systematic introduction into the context of managing current bibliography and then case studies follow targeted on specific problems of internet material bibliography treatment. Firstly one discusses the issues related to bibliographical processing of online documents (web pages, online journals, etc.), which are in complex and variable relations to those available in print. An attention is paid to the methodological issues, in particular providing criteria of web resources selection. The need for archivization of bibliographically processed materials which we assess as the crucial element of any systematic bibliographical processing of Internet materials will be also highlighted. In the following part study presents the preliminarily classification of the new specific genres of internet content: blogs and literary forums. Firstly the Polish literary blogosphere is analysed and preliminarily typology of this document type is introduced. Later a phenomenon of literary forums is taken into consideration. Based on an example of poetry forum Nieszuflada.pl more detailed quantitative analysis of this resource type is given and issues of authorship attribution in the digital environment are discussed.
Internetové stránky jsme si zvykli navštěvovat prakticky denně. Hledáme na nich informace, zábavu a poučení. K nevšedním námětům, které mohou připoutat pozornost mládeže i dospělých, patří parabolický let. V tomto díle rubriky "Ve zkratce" si všimneme fyzikální podstaty parabolického letu a kriticky posoudíme, jak jsou informace o něm prezentovány na domácích i zahraničních webových stránkách. Uvědomíme si také, zda a jak dobře umíme číst z grafů., Lenka Czudková, Jana Musilová, Tomáš Nečas., and Obsahuje bibliografii
E-government becomes an important element of the emerging e-societies. There is a great diversity of strategies, policies and results related to its introduction. Educational and cultural conditions and possibilities are vital because they generate - or not - interests in ICTs and their various applications. So capacity building for e-government is a coplex porcess, not limited to introduciton of technological and organizational actions. Moreover e-government is costly and will require soon not only social but also econimic evaluation. These issues are explored in an illustrative case study of e-services in Poland. and Lech W.

The Internet has become an important source of information for physicians seeking immediate data for the management of patients and for those developing decision-making methodologies and guidelines for clinical practice. In this study, components and subsystems of a medical decision support system are presented. An artificial neural network model, which is one of the subsystems of the differential diagnosis component, has been proposed as a reasoning tool to support medical diagnosis. The input data of artificial neural network models used in different medical diagnosis can be obtained via the Internet. The present study is concerned with the application of artificial neural network model to diabetes prediction. Demographic and medical data of diabetics and non-diabetics obtained via the Internet were used as the artificial neural network inputs. The accuracy of the neural network's results has shown that the diabetes prediction is feasible by the neural network described in this study.
