The World Spider Trait database: a centralized global open repository for curated data on spider traits
Spiders are a highly diversified group of arthropods and play an important role in terrestrial ecosystems as ubiquitous predators, which makes them a suitable group to test a variety of eco-evolutionary hypotheses. For this purpose, knowledge of a diverse range of species traits is required. Until now, data on spider traits have been scattered across thousands of publications produced for over two centuries and written in diverse languages. To facilitate access to such data, we developed an online database for archiving and accessing spider traits at a global scale. The database has been designed to accommodate a great variety of traits (e.g. ecological, behavioural and morphological) measured at individual, species or higher taxonomic levels. Records are accompanied by extensive metadata (e.g. location and method). The database is curated by an expert team, regularly updated and open to any user. A future goal of the growing database is to include all published and unpublished data on spider traits provided by experts worldwide and to facilitate broad cross-taxon assays in functional ecology and comparative biology.Fil: PekĂĄr, Stano.

ANALYZA EKONOMICKEHO PRINOSU A FINANCNYCH NAKLADOV INFORMACNYCH SYSTEMOV PODNIKATEL'SKYCH SUBJEKTOV
The question of investing a lot of money by business entities in the development and operation of information systems in comparison with their economic gains is a long-term problem, depending on several factors. The problem is being solved by many authors as well as company's experts in information technologies. From analysis of heavy expenses of the information systems in the agriculture sector, conclusions can be drawn about financial gain from these systems used in different conditions of agricultural production, among which are cost amount, quantification of economic gain and assessment of risks that may cause the information system collapse. Using the coefficient of economic efficiency of an information system, it is possible to determine in particular companies what sort of quantified effects can be attained (a plan) or have been attained (reality) per Slovak koruna of expanded one-time investment. A number of years that this investment needs repaying can be calculated by the indicator of a period of return on investment in the company's information system

ANALYZA BEZPECNOSTI INFORMACNYCH SYSTEMOV - SUCASNY STAV V PODMIENKACH AGROREZORTU NA SLOVENSKU
Information systems' security and information protection are becoming commonly used terms in the world. The need to increase the secrity comes from rising real and potential security threats. It is important to make information systems resist the forces they may be subJeted to. Adequate degree of safety of information systems can guarantee every business continual development, as well as avoid ndesirable loss of know-how. Information systems have markedly entered the management in Agrosector; however, Agrosector has in the field of IT a lot of drawbacks, which have to be analyzed and solved
ANALSIZA FINANOWCH NAKLADOV A EKONOMICKEHO PRINOSU INFORMAOWCH SYSTEMOV V PODNIKATELSKYH SUBJEKTOCH
Spending high cost on creation and operation of the information systems in business enterprises in comparison with their economic gain is a long-term problem, depending on several factors. Based on the analysis of the costs spent on the information systems designed for agriculture, it is possible to implement the intentions concerning an economic gain of the information systems used under different conditions of agricultural production. These include a sum of costs, an economic gain in quantitative terms, and an estimation of the risks which can result in unsuccessful creation or updating of the information system
INFORMATIZACIA REZORTU PODOHOSPODARSTVA PO VSTUPE SLOVENSKA DO EUROPSKEJ UNIE
Quality information and information services have nowadays a strategic economic and social importance. State management, management of large and small business entities in the information society is based on quality information. One of the goals of medium term agricultural policy for the years 2004-2006 is to finish and harmonise the information system of the sector. The program of information and communication technology itself consists of systematic part, specialisation part and integrated solutions. Information strategy in the individual companies should be realised in a way to be able to cope with new trends in the development of informative systems and technologies. One of the basic conditions to achieve the competitiveness of agro enterprises after the EU accession is to reassess the company information system architecture and enable the access of enterprises to current information in real time
Une enquĂȘte sur la prĂ©vention des naissances et le plan familial en TchĂ©coslovaquie
Les renseignements ont longtemps manquĂ© sur la dĂ©mographie des rĂ©publiques populaires socialistes, tant pour les chiffres que pour les concepts. Depuis quelques annĂ©es, une phase nouvelle s'est ouverte, pour les recherches comme pour les publications. En TchĂ©coslovaquie, en particulier, l'Office national de statistique publie une revue trimestrielle « Demografie », dont les articles et documents sont pleins d'intĂ©rĂȘt. Une enquĂȘte sur le mariage, la contraception et l'avortement a Ă©tĂ© commencĂ©e en 1958. Les rĂ©sultats de cette enquĂȘte (qui, pratiquĂ©e sur un sujet si rĂ©servĂ© jusque-lĂ , marquait elle-mĂȘme une date) ont Ă©tĂ© publiĂ©s dans les numĂ©ros 1 Ă 4 de la revue en 1961, par Vladimir Srb, Milan KuÄera et Dagmar VysuĆ ilova. Les difficultĂ©s de langue n'avaient pas permis jusqu'ici Ă l'I.N.E.D. de donner une analyse de cette importante enquĂȘte. Elles ont pu ĂȘtre surmontĂ©es grĂące Ă la prĂ©sence de M. Z. Pavlik, dĂ©mographe tchĂšque, qui a fait un stage Ă l'I.N.E.D. en 1963. Le texte de l'article ci-dessous, rĂ©digĂ© par lui-mĂȘme et par Mme Chantai Blayo, est un rĂ©sumĂ© fidĂšle de l'Ă©tude publiĂ©e dans « Demografie ».Srb Vladimir, Kucera Milan, VysuĆĄilova Dagmar.
