    Diplomsko delo prikazuje določanje Al, As, Ba, Cd, Co, Cr, Cu, Fe, Ga, Mn, Mo, Ni, Pb, Sn, Sr, Tl in Zn v različnih vzorcih vin iz Dolenjske z uporabo induktivno sklopljene plazme z masno spektrometrijo. Za namene analize vzorcev vin se je izvedel mikrovalovni kislinski razklop. Za vseh 17 težkih kovin smo metodo delno validirali. Določili smo mejo zaznavnosti, mejo določljivosti, linearno koncentracijsko območje, točnost in natančnost. Namen dela je bil določiti koncentracije težkih kovin v belih vinih in rdečih vinih, domačih vinih in vinih, kupljenih v trgovini, ter v različnih letnikih vin (2020–2023). Pridobljene podatke smo primerjali s študijami, ki so postavile mejne koncentracije za vina ter ugotovili, da nekateri vzorci domačih vin presegajo mejne koncentracije za Cd, Pb, Cu in Zn, pri vzorcih vin iz trgovin pa en vzorec vin presega mejno koncentracijo za Cu.The thesis presents the determination of Al, As, Ba, Cd, Co, Cr, Cu, Fe, Ga, Mn, Mo, Ni, Pb, Sn, Sr, Tl, and Zn in various wine samples from Lower Carniola region using inductively coupled plasma mass spectrometry. The wine samples underwent microwave-assisted wet digestion before analysis. The method was partially validated for all 17 heavy metals. The limit of detection, limit of quantification, linear concentration range, accuracy, and precision were determined. The aim of this work was to determine the concentrations of heavy metals in white wines and red wines, domestic wines and store-bought wines, and in different vintages of wines (2020–2023). The obtained data was compared with studies that set the limit concentrations for wines and found that some samples of domestic wines exceeded the limit concentrations for Cd, Pb, Cu, and Zn, while one store-bought wine exceeded the limit concentration for Cu

    Magistrsko delo se osredotoča na izvajalsko prakso za kljunasto flavto in njen razvoj skozi različna slogovna obdobja s ciljem osvetliti njen umetniški potencial ter razumeti vlogo izvajalca v historičnih in sodobnih kontekstih. Izhajamo iz predpostavke, da interpretacija glasbene literature presega zgolj tehnično izvedbo in vključuje kompleksno prepletanje zgodovinskega znanja, estetskih odločitev in osebne umetniške presoje. V teoretičnem delu smo obravnavali razvoj kljunaste flavte in izvajalskih praks od srednjega veka do sodobnosti. Skozi primerjalno analizo dveh slogovno kontrastnih skladb – Daphne, Jacoba van Eycka in Black Intention, Makija Ishiija, smo raziskali razlike v zvočni zasnovi, tehničnih zahtevah, estetskih pristopih in vlogi izvajalca. Obe skladbi sta napisani za isti tip inštrumenta, vendar predstavljata raznolikost izraznih možnosti in interpretativnih pristopov, ki jih kljunasta flavta omogoča. Skladbi, ki sta v magistrskem delu predmet analize, bosta izvedeni v živo na zagovoru. Namen dela je pokazati, kako kompleksne so izvajalske odločitve ter raziskati razmerje med tradicijo in sodobnimi pristopi. Kljunasto flavto obravnavamo kot izrazno bogat inštrument, ki presega časovne in slogovne okvire. Z raziskavo želimo prispevati k boljšemu razumevanju izvajalske prakse kot dejavnika, ki pomembno oblikuje umetniški značaj izvedbe ter poudariti pomen zgodovinske zavesti ob odprtosti do sodobnih izraznih možnosti.Master\u27s thesis explores the performance practice of the recorder and its evolution across various stylistic periods with the aim of illuminating its artistic potential and examining the role of the performer in both historical and contemporary contexts. The work is grounded in the premise that the interpretation of musical literature transcends technical execution and entails a complex interplay of historical knowledge, aesthetic judgment, and personal artistic expression. The theoretical section addresses the development of the recorder and performance practices from the Middle Ages to the present day. Through a comparative analysis of two stylistically contrasting works—Daphne by Jacob van Eyck and Black Intention by Maki Ishii—the thesis investigates differences in sound design, technical demands, aesthetic approaches, and the performer\u27s role. Although written for the same type of instrument, these pieces exemplify the wide range of expressive and interpretative possibilities the recorder affords. Both works will be performed live during the master\u27s recital. The primary objective of this thesis is to demonstrate the complexity of performance decisions and to examine the dynamic relationship between tradition and contemporary approaches. The recorder is presented as an instrument of rich expressiveness that transcends temporal and stylistic boundaries. This research contributes to a deeper understanding of performance practice as a vital element in shaping the artistic character of musical interpretation, while underscoring the importance of historical awareness and openness to modern expressive techniques

    Za ocenjevanje in izbor kadrov se uporablja različne metode, med drugimi psihološko testiranje, opazovanje vedenja in metodo ocenjevalnega centra. Metode se med seboj razlikujejo v psihometričnih značilnostih ter v prednostih in omejitvah njihove uporabe. Zanimalo nas je, ali se ocene, pridobljene pri nalogah ocenjevalnega centra, povezujejo z vrednostmi, pridobljenimi s psihološkimi testi in z opazovanjem vedenja ter s čim lahko najbolje napovemo uspešnost pri metodi ocenjevalnega centra. Vzorec je obsegal 145 udeležencev, ki so med postopkom ocenjevanja in izbora kadrov v določenem podjetju izpolnili štiri vprašalnike (Test nizov, Profil indeks emocij, Vprašalnik za merjenje strukture osebnosti po modelu "Velikih pet" in Vprašalnik timskih vlog) ter sodelovali v ocenjevalnem centru, ki je bil sestavljen iz devetih nalog. Posebej je bilo opazovano tudi njihovo vedenje. Analiza je pokazala, da so osebnostne lastnosti v splošnem nizko povezane z ocenami pri nalogah ocenjevalnega centra in s kompetencami, ki so bile ocenjene med opazovanjem vedenja. Izmed vseh spremenljivk, ki so bile preučevane v raziskavi, pa uspešnost pri metodi ocenjevalnega centra pomembno napovedujeta dve, in sicer inteligentnost ter starost. Sklepamo, da je uporaba metode ocenjevalnega centra smiselna, saj z njo v postopku ocenjevanja in izbora kadrov o kandidatih pridobimo podatke, ki jih ne bi mogli pridobiti z uporabo predhodnih metod. Rezultati se večinoma ujemajo z ugotovitvami dosedanjih raziskav, v besedilu pa podrobneje opišemo tudi neskladja in njihove možne vzroke.Various methods are used to assess and select staff, including psychological testing, behavioral observation, and the assessment center method. The methods differ in psychometric characteristics and in the advantages and limitations of their use. We were interested in whether the assessments obtained in the assessment center tasks are related to the values obtained through psychological tests and observation of behavior, and how we can best predict the success of the assessment center method. The sample consisted of 145 participants who completed four questionnaires (Test of Series, Emotions Profile Index, Big Five Questionnaire and Belbin Team Role Inventory) during the selection process in a particular company and participated in the assessment center, which consisted of nine tasks. Their behavior was also observed. The analysis showed that personality traits are generally low connected to assessments in assessment center tasks and to competencies that were assessed during behavioral observation. Of all the variables studied in the research, the assessment center success is significantly predicted by two, namely intelligence and age. We conclude that the use of the assessment center method makes sense, as it provides information on candidates in the selection process that could not be obtained using previous methods. The results are mostly in line with the findings of previous research. However, the text describes in more detail the discrepancies and their possible causes
