Indoor radon in Slovenia
VaupotiJanja
Nuclear Technology and Radiation Protection , 2003, DOI: 10.2298/ntrp0302036v
Abstract: The Slovenian Radon Programme started in 1990. Since then, radon and radon short-lived decay products have been surveyed in 730 kindergartens, 890 schools, 1000 randomly selected homes, 5 major spas, 26 major hospitals, 10 major municipal water supply plants, and 8 major wineries. Alpha scintillation cells, etched track detectors, electret-based detectors and various continuously measuring devices have been used. On the basis of estimated effective doses, decisions were made on appropriate mitigation. In total, 35 buildings have been appropriately modified. The programme is displayed and results reviewed chronologically and discussed.
Nanoaerosols Including Radon Decay Products in Outdoor and Indoor Air at a Suburban Site
Mateja Smerajec,Janja Vaupoti
Journal of Toxicology , 2012, DOI: 10.1155/2012/510876
Abstract: Nanoaerosols have been monitored inside a kitchen and in the courtyard of a suburban farmhouse. Total number concentration and number size distribution (5–1000?nm) of general aerosol particles, as measured with a Grimm Aerosol SMPS+C 5.400 instrument outdoors, were mainly influenced by solar radiation and use of farming equipment, while, indoors, they were drastically changed by human activity in the kitchen. In contrast, activity concentrations of the short-lived radon decay products 218Po, 214Pb, and 214Bi, both those attached to aerosol particles and those not attached, measured with a Sarad EQF3020-2 device, did not appear to be dependent on these activities, except on opening and closing of the kitchen window. Neither did a large increase in concentration of aerosol particles smaller than 10 or 20?nm, with which the unattached radon products are associated, augment the fraction of the unattached decay products significantly. 1. Introduction Air is an aerosol with suspended particulate matter. The particle size ranges from several nm for molecular clusters to about 100?μm for fog droplets and dust particles. Particles larger than 100?μm cannot remain suspended in air and may not therefore be considered as aerosols [1]. The particle size, structure, and chemical composition of aerosols are of key importance for climate and environmental health and are therefore of great interest to aerosol scientists, atmospheric chemists and physicists, and toxicologists and are of serious concern to the regulatory bodies responsible for public health [2–4]. Particulates are emitted by a number of various human activities. They are released by various industries, such as thermal power plants burning fossil fuel or biomass, incinerators, mineral mining and milling facilities, and others. In urban areas where an important or even major particle source is traffic [3–9], aerosol concentration is an order of magnitude higher than those in suburban or rural areas. Nanoparticles are also produced intentionally [10] to be used as constituents in electronics, medicines, pharmaceuticals, cosmetics, paints, and a variety of other consumers products. Nanotechnology is increasing fast and so is the possibility for the nanoparticles to appear in the air of workplaces and be released into the outdoor atmosphere and subsequently enter living environments [11]. During breathing of air, aerosol particulates are partly deposited on the walls of the respiratory tract. Mathematical simulations have shown that their deposition strongly depends on the particle size [12–15]. Thus, for
The influence of geology on elevated radon concentrations in Slovenian schools and kindergartens
Andreja Popit,Janja Vaupoti
Geologija , 2002,
Abstract: 76 instantaneous indoor radon concentrations above the Slovenian action level of 400 Bqm-3 were selected from the database of 1600 radon concentrations in kindergartens and schools, assembled during the Slovenian National Radon Programme. A relationship wasfound between indoor radon concentrations, and geology of rocks under the foundations (uranium content, permeability, porosity, tectonic fractures) and the quality of building construction.
Reasons for Elevated Radon Levels Inside the Building in Diva a
Petra ?vab,Janja Vaupoti,Tadej Dolenec
Geologija , 2006,
Abstract: A radon (222Rn) survey at a workplace in a public building in the town of Diva a, Slovenia, showed radon concentrations as high as 20,000 Bq m–3, with average values of 9020 Bq m–3 in winter and 2890 Bq m–3 in summer. The main radon source is an under-floor channel connecting rooms on the ground floor.Elevated radon levels at the site are possibly related to a fracture zone connected to a nearby fault.
Advances in the treatment of metastatic colorectal carcinoma
Janja Ocvirk
Radiology and Oncology , 2009, DOI: 10.2478/v10019-009-0004-1
Abstract: Background. In most cases, metastatic colorectal cancer is incurable; however, the prognosis and survival of these patients have significantly improved in the last 6 years. A few years back, the only efficient drug for colorectal carcinoma, 5-fluoruracil, yielded the mean survival of 10 months, whereas today, the survival rates of 20 months or more may be obtained by using new cytostatics. In the last six years, five new drugs were registered for the treatment of metastatic colorectal cancer. These are three cytostatics (capecitabine, irinotecan, oxaliplatin) and two target drugs (cetuximab and bevacizumab). Conclusions. A combined treatment assures a better quality of life, and longer remissions and overall survival. The combination of cytostatics and target drugs improves particularly the mean survival rate, which may be longer than 30 months. These combinations of drugs used together with surgical treatment of lung and liver metastases may result in complete remission. An important research achievement of this year is the determination of KRAS mutations. The KRAS gene is the first biomarker that predicts how well patients will respond to certain combination of treatment.
Ekonomska u inkovitost notranjega trga EU (EU internal Market and Its Economic Efficiency)
Janja Hojnik
LeXonomica : Journal of Law and Economics , 2010,
Abstract: Process of regional economic integration in Europe has in the last decades been determined by expansions in various dimensions – substantially as well as geographically. Market integration is thereby presented as an instrument to enhance prosperity. The article analyses economic effect of the EU internal market, i. e. whether and to what extend has the internal market enhanced economic prosperity and income in Europe in the last half-century. From methodological point of view we are dealing with a very complex question, which has been approached in various ways by various economic studies. The article is based on a study performed by a Dutch bureau CPB, which was assessing additional economic effect of the EU internal market – i.e. in addition to alternative forms of market integration, existing also in economic relations with third countries. The authoress concludes that the EU internal market has achieved the highest economic effect in the field of foreign direct investments; economic effect of free movement of goods is comparable to foreign direct investments, whereas the economic effect of free movement of services is being more moderate, however, having considerable potential for increase. Economic effect of free movement of workers is not analysed in the article considering low level of migration flows between the EU member states.
Ordoliberalizem - teorija povezovanja prava in ekonomije (Ordoliberalism - Theory of Law and Economics Connecting )
Janja Hojnik
LeXonomica : Journal of Law and Economics , 2009,
Abstract: The article deals with theory of ordoliberalism, which is a less known theory of connecting law and economy into a single system of so-called economic constitution. It is a liberalistic theory of understanding market relations, nevertheless, it emphasises that freedom on the market is not to be achieved without legal intervention, considering that power of entities on the market differs and therefore more powerful entities restrict freedom and rights of the weaker – which results in monopolies, asymmetries of information and negative externalities. Ordoliberalism is a theory of authoritative liberalism that emphasises that law is an indispensable market accompanier, since it assures order on it. Theory of ordoliberalism is relevant also for EU market integration, because it advocates the need for strong supranational institutions, bound by the EU economic constitution, which replaces compartmentalized state market interventions.

The Field Trip as Part of Spatial (Architectural) Design Art Classes
Janja Bati?
CEPS Journal : Center for Educational Policy Studies Journal , 2011,
Abstract: Spatial (architectural) design is one of five fields introduced to pupils as part of art education. In planning architectural design tasks, one should take into consideration the particularities of the architectural design process and enable pupils to experience space and relationships within space through their own movement. Furthermore, pupils should have an opportunity to play the roles of (critical) users as well as co-creators or spatial planners. In this respect, the field trip plays a vital role, as it allows pupils to experience (architectural) space through their own movement, their senses and in a real environment. The architectural experience that the pupils gain differs from their everyday experience of moving through space, as the former is based on education and training, and thus helps pupils develop architecture appreciation.
The Complexity of Policy Mirroring: The Connection between International and Slovenian Higher Education Policy Discourse
Janja Komljenovi?
CEPS Journal : Center for Educational Policy Studies Journal , 2012,
Abstract: The contemporary economic imaginary of the ‘knowledge-based economy’is changing the perception of higher education in Europe. The goals ofhigher education are changing and reform of institutions is predicted. The present article examines these reforms and onceptualisations of higher education by presenting the results of discourse analysis of 47 international policy documents at the European level and two comprehensive national strategies of the Republic of Slovenia for higher education, research and innovation. Based on the analysis of the European documents, the article suggests that two main discourses are constructed: a) ‘the research-based society and economy’, and b) ‘reforming the university’. These present the emergence of a new idea of higher education at the international and national levels. The article investigates the extent to which these discourses are present in Slovenian higher education policy. The findings show that Slovenian discourse hesitates to embrace them fully. In particular, the idea of the managerial university is marginal in Slovenian discourse.
