    Quality Assurance (QA)
    Opis:
    Basing on alanine solid state/electron paramagnetic resonance (EPR) dosimetry, a supplementary method of cumulatively recording the therapeutic dose received by ocular cancer patients undergoing fractionated proton radiotherapy is proposed. By applying alanine dosimetry during the delivery of consecutive fractions, the dose received within each fraction can be read out by EPR spectrometry and a fi nal permanent cumulative record of the total dose delivered obtained. The dose response of the alanine detector was found to be practically independent on its position within the extended proton Bragg peak region. Dose measurements based on entrance dose recorded in proton beams individually formed for each patient are presented. The described method will be applied as a complementary Quality Assurance procedure for patients undergoing proton radiotherapy at the Institute of Nuclear Physics, Polish Academy of Sciences, Krakow, Poland (IFJ PAN).

    Opis:
    W pracy omówiono podstawy wykonywania badania spirometrycznego ze uwzględnieniem procedury pomiaru krzywej przepływ – objętość oraz kryteriów jakościowych oceny spirometrii na podstawie zaleceń standaryzacyjnych. Dokonano analizy jakości pomiaru krzywej przepływ objętość w trzech grupach: u dzieci, u osób w podeszłym wieku oraz uzyskanych w trakcie Światowego Dnia Spirometrii. Podkreślono rolę personelu wykonującego badania oraz sformułowano kilka postulatów dotyczących realizacji sprzętowo – programowych systemów spirometrycznych.
    The authors present description of the spirometry focusing on forced flow volume loop measurements and corresponding requirements according to ERS/ATS 2005 [2,3] and PTChP [4] 2006 statements. The introduction to actually applied solutions in supporting automatic assessment of quality assurance (QA)criteria is also presented. The quality analysis of spirometric measurements was performed for three different groups: children younger than 10 years, the group of elderly people and the spirometry obtained during the World Spirometry Day. All the three groups expressed different quality problems: the main problem in children group was too restrictive value of the demanded time of forced expiration (especially regarding significant correlation between the age and the forced expiratory time) – only 23.9% children fulfilled this re-quirements, in the group of elderly people lack of plateau on the expiratory end was the mostly registered error – 60,2%. In the spirometries obtained during the World Spirometry Day the significant number of non-repetitive measurements and the small number of properly performed measurements (only 28%) was the most interesting aspect. The authors concluded that competence and qualifications of the laboratory staff played the most important role in ensuring the quality of spirometry. However, some demands could be addressed to manufacturers of spirometry equipment.

    Opis:
    A plastic can be turn to millions fragments of microplastic particles by anthropogenic activities and environmental events (such as wind, UV light, the water wave action). Due to their surface hydrophobicity, adsorb persistent organic pollutants, the potential to transport contaminants and persistent properties, microplastics have the potential to become widely dispersed in the water environment via hydrodynamic processes and water currents. Plastic materials are durable and rather than decomposing, they break down into small plastic particles over time. These small particles that are less than 5 mm usually defined as microplastic. As a consequence of large plastic production rates, plastic waste accumulation in natural environment rapidly increased all over the World. However, the effects of plastic wastes in different ecosystems are still largely unknown. Water and wastewater treatment plants are important facilities to estimate plastic waste release or retention amount to the environment. The field of microplastic pollution is in its infancy, and there are not yet widely accepted standards for sample collection, laboratory analyses, quality assurance/quality control (QA/QC) or reporting of microplastics in environmental samples. Up to date, few studies have quantified microplastics in wastewater. Moreover, the lack of a standardized and applicable method to identify microplastics in complex samples, such as wastewater, has limited the accurate assessment of microplastics and may lead to an incorrect estimation. In this study, microplastic sampling techniques, extraction methods and identification methods of microplastics in wastewater were compared. It was concluded that studies were mostly done with grap type sampling, wet peroxite oxidation and identification methods with microscope and Fourier Transform Infrared Spectrophotometer (FT-IR). In the FT-IR analysis to determine the polymer structure of microplastics, the most common type of polymer was found to be polypropylene (PP) and polyethylene (PE).

    Opis:
    Since its inception, the governments of 29 European countries (member states of the Bologna Declaration in 1999) had as their main target the creation of a common and coherent system of Higher Education Area in Europe (EHEA). The main intention for the creation of a ‘European Education Area’ was the fostering of student mobility and employability in order to strengthen competition and to make the European Higher Education more attractive. The main focus of this paper is the analysis of the National Periodic Reports for the period 2004-2009, the Albanian National Strategy for Higher Education 2014-2020, and a study on the presence of Quality Assurance Institutions in Higher Education, based on the report from the Education, Audiovisual and Culture Exécutive Agency. The methodology chosen by the authors of this paper is to divide into four groups the countries that have established a national or private Quality Assurance Institution as part of their higher education system in order to assess whether the existence/presence of such institutions act as key instruments to ensuring the quality of higher education. It is recommended that Albania even though listed in the group of countries establishing a National Quality Assurance Agency, can ‘maybe’ follow the model of those European countries that have established a further Private Quality Assurance Agency in addition to the National Quality Assurance Agency. It is believed that the further establishment of a carefully chosen private quality assurance agency (ENQA or EQAR) would ensure quality and guarantee transparency in higher education.

    Opis:
    Terminology is significant for professional communication and ipso facto for translation quality assurance (QA). To deliver a translation of high quality, it is crucial to have all new terms that occur in professional discourse collected, stored and managed properly by means of terminology databases (TDBs). In this paper I will try to define ‘quality’ in relation to TDBs and to determine the methodology and criteria that need to be considered by evaluating a TDB in the context of its reliability.
    Terminologia jest kluczowa w komunikacji specjalistycznej, a tym samym również w zapewnieniu jakości tłumaczenia. Aby dostarczyć tłumaczenie najwyżej jakości istotne jest, aby terminy pojawiające się w dyskursie specjalistycznym były zbierane, przechowywane i zarządzane przy pomocy baz danych terminologicznych. W artykule podejmę próbę zdefiniowania „jakości” w odniesieniu do baz danych terminologicznych oraz próbę określenia metodologii i kryteriów oceny danej bazy terminologicznej w kontekście jej jakości (wiarygodności).
