Experimental investigation on laser machining of microfluidic channels in micro mold inserts
No full textLaser micromachining is an effective technique for fabricating intricate microfeatures with high precision and minimal thermal deformation. In this study, micropillars were fabricated on P20 steel injection mould inserts for microfluidic channel applications using a CO▫▫ laser machining system. The primary objective of this work is to optimize laser machining parameters to achieve high dimensional accuracy and stable material removal during micropillar fabrication. Laser speed, laser power, and pulse frequency were selected as key input parameters influencing the geometrical accuracy and performance of the microstructures. An optimal combination of laser speed 525 mm s▫▫, power 32 W, and frequency 23 kHz was identified, resulting in highly repeatable micropillar geometry. The fabricated micropillars exhibited low dimensional variation, with length and width variations limited to 0.5% and 1.9%, respectively, while the material removal rate showed a variation of 3.0%, indicating consistent machining performance. Overall, the results demonstrate that appropriate optimization of laser parameters enables precise and repeatable fabrication of micropillars on P20 mold inserts, highlighting the suitability of laser micromachining for producing high-quality micro mold inserts for injection- molded microfluidic applications.Lasersko graviranje je učinkovita tehnologija izdelave kompleksnih mikrostruktur z visoko natančnostjo in minimalnimi toplotnimi vplivi. V raziskavi smo na orodnih iz jekla P20 na orodnih vložkih za brizganje plastike izdelali mikrostebričke v mikrofluidniih kanalih z uporabo CO▫▫ laserskega sistema. Glavni cilj je bil optimirati parametre laserske obdelave za doseganje visoke dimenzijske natančnosti in stabilnega odvzema materiala. Kot ključne vhodne parametre smo izbrali hitrost laserskega pomika, lasersko moč in frekvenco pulzov. Določena je bila optimalna kombinacija: hitrost 525 mm s▫▫, moč 32 W in frekvenca 23 kHz, ki zagotovlja natančno in ponovljivo izdelano geometrijo mikrostebričkov. Izdelani mikrostebrički izkazujejo nizko dimenzijsko variabilnost (odstopanja dolžine do 0,5 % in širine do 1,9 %), variacija hitrosti odnašanja materiala pa znaša 3,0 %. Rezultati potrjujejo, da ustrezna optimizacija vhodnih parametrov omogoča natančno in ponovljivo izdelavo mikrostebričkov na vložkih iz P20, ter tako dokazujemo primernost laserskega gravoranja za izdelavo kakovostnih orodnih vložkov

No full textWe present an interactive visualization system for exploring named entities and their relationships across document collections. The system is designed around a graph-based representation that integrates three types of nodes: documents, entity mentions, and entities. Connections capture two key relationship types: (i) identical entities across contexts, and (ii) co-locations of mentions within documents. Multiple coordinated views enable users to examine entity occurrences, discover clusters of related mentions, and explore higher-level entity group relationships. To support lexible and iterative exploration, the interface ofers fuzzy views with approximate connections, as well as tools for interactively editing the graph by adding or removing links, entities, and mentions, as well as editing entity terms. Additional interaction features include iltering, mini-map navigation, and export options to JSON or image formats for downstream analysis and reporting. This approach contributes to human-centered exploration of entity-rich text data by combining graph visualization, interactive reinement, and adaptable perspectives on relationships
Vizualni dnevnik kot način za krepitev sposobnosti samorefleksije pri dijakih
No full textArt allows us to look within ourselves, to learn who we are and what interests us. It connects us to our thoughts, our feelings, our perceptions, and our external reality and experiences. Artistic expression enables students to think about themselves and their feelings, take the perspective of another while evaluating their artworks, set goals and organise the course of their creative work. Therefore, it is not difficult to establish a connection between artistic expression and strengthening social emotional competencies. In a study conducted in the 2023/24 school year, a case study explored whether creating a visual journal in the form of an artist’s book can help students recognise their thoughts, emotions and values. In the case study, we included one class of first-year secondary school students, who participated voluntarily, as well as their teacher. We first presented the CASEL model to the students in connection with the artworks of artists whose works deal with topics related to social and emotional competences. The mentor presented the artist’s book in the form of a visual journal as a special artistic form. The students’ task was to think about themselves, their wellbeing, values and actions, and to make real-time reflections on their day with the help of their own visual journal. In their spare time, the students compiled a visual journal over a few weeks, occasionally consulting with the teacher. Data were collected through an analysis of the resulting visual journals, a questionnaire for students and an interview with the teacher.Umetnost nam omogoča, da pogledamo vase, spoznamo, kdo smo in kaj nas zanima. Povezuje nas z našimi mislimi, občutki, zaznavami ter z našo zunanjo realnostjo in izkušnjami. Umetniško izražanje omogoča dijakom, da razmišljajo o sebi in svojih občutkih, zavzamejo perspektivo drugega pri vrednotenju svojih likovnih del, si postavijo cilje in organizirajo potek svojega ustvarjalnega dela. Zato ni težko prepoznati povezave med likovnim izražanjem in krepitvijo socialno-čustvenih kompetenc. V raziskavi, izvedeni v šolskem letu 2023/24, smo s pomočjo študije primera ugotavljali, ali lahko ustvarjanje vizualnega dnevnika v obliki knjige umetnika pomaga dijakom prepoznati njihove misli, čustva in vrednote. V študijo primera smo vključili en razred dijakov 1. letnika srednje šole, ki so sodelovali prostovoljno, in njihovo učiteljico. Dijakom smo najprej predstavili model CASEL v povezavi z likovnimi deli umetnikov, ki se ukvarjajo s temami, povezanimi s socialnimi in čustvenimi kompetencami. Mentorica je kot posebno umetniško obliko predstavila knjigo umetnika v obliki vizualnega dnevnika. Naloga dijakov je bila razmišljati o sebi, svojem počutju, vrednotah in o dejanjih ter s pomočjo lastnega vizualnega dnevnika razmišljati o svojem dnevu. V prostem času so dijaki nekaj tednov sestavljali vizualni dnevnik, občasno pa so se posvetovali z učiteljem. Podatki so bili zbrani z analizo nastalih vizualnih dnevnikov, vprašalnikom za učence in z intervjujem z mentorico
Postati angažiran plesni strokovnjak prek umetniško zasnovanih projektov za vključevanje skupnosti
No full textPostgraduate dance education students can develop a practice of arts-based, engaged scholarship by applying their disciplinary knowledge in collaboration with community partners to enact projects that benefit local, regional and/or global communities and their own scholarship. The present article analyses seven arts-based research projects required as part of the Studio Seminar course for doctoral dance education students at Teachers College, Columbia University. The specific goals of the research project were (a) to assess the level of community engagement present in seven Studio Seminar projects, (b) to determine whether or not the criteria of “evocation and illumination” were fulfilled in the Studio Seminar projects, and (c) to determine the knowledge gained by the participating students who conducted and reflected upon the Studio Seminar projects. Two cohorts of students participated in the study: Cohort 1 (three par-ticipants), who completed the course in 2021, and Cohort 3 (four partici-pants), who completed the course in 2023. The data were collected and analysed based on the arts-based research evaluation criteria of evocation and illumination, and the community engagement criteria of co-creation, co-implementation, co-assessment and co-dissemination. The results of this exploratory study reveal that the community engagement criteria of co-creation, co-implementation and co-assessment were present in all of the projects, but co-dissemination was only possible for the students who completed their projects in the first cohort. In addition, the arts-based research criteria of evocation and illumination were present in all seven projects. Furthermore, the results of a Community Engagement Questionnaire revealed that the projects had a positive impact on the students’ dissertation goals and their plans for future community engagement projects. In conclusion, providing postgraduate dance education students with guidance in developing arts-based, community-engaged projects assists in their development as engaged scholars.Podiplomski študentje plesne pedagogike lahko razvijejo prakso angažiranega, na umetnosti temelječega raziskovanja, tako da svoje strokovno znanje uporabijo v sodelovanju s partnerji iz skupnosti pri izvedbi projektov, ki koristijo lokalnim, regionalnim in/ali globalnim skupnostim, ter hkrati prispevajo k njihovemu lastnemu raziskovalnemu delu. Ta članek analizira sedem projektov na umetnosti temelječega raziskovanja, ki so obvezen del predmeta Studio Seminar za doktorske študente plesne pedagogike na Teachers College Univerze Columbia. Cilji raziskave so bili: a) oceniti raven vključenosti skupnosti v sedmih projektih Studio Seminarb) ugotoviti, ali so bila v projektih izpolnjena merila evokacije (sprožanje estetskega ali reflektivnega odziva) in osvetlitve (prikaz ali osvetlitev kompleksne teme skozi umetniško prakso)c) raziskati, kakšno znanje so pridobili študentje, ki so pri projektih sodelovali in jih reflektirali. V raziskavi sta sodelovali dve skupini študentov: skupina 1 (trije udeleženci), ki je predmet zaključila leta 2021, in skupina 3 (štirje udeleženci), ki je pred-met zaključila leta 2023. Podatki so bili zbrani in analizirani na podlagi meril za ocenjevanje na umetnosti temelječega raziskovanja – evokacije in osvetlitve – ter meril za vključevanje skupnosti, kot sta soustvarjanje in souporaba. Rezultati kažejo, da so bila merila vključevanja skupnosti prisotna v vseh projektihsoustvarjanje je bilo prisotno pri vseh, medtem ko je bila souporaba značilna predvsem za projekte skupine 1. Poleg tega sta bili evokacija in osvetlitev izraženi v vseh sedmih projektih. Rezultati vprašalnika o vključevanju skupnosti so pokazali, da so projekti pozitivno vplivali na študente glede njihovih študijskih ciljev in prihodnjih načrtov za projekte v sodelovanju s skupnostjo. Sklepno lahko ugotovimo, da usmerjanje podiplomskih študentov plesa k razvoju projektov na umetnosti temelječega raziskovanja v povezavi s skupnostjo prispeva k njihovemu oblikovanju kot angažiranih raziskovalcev
Covid-19
No full textWe examine how pandemic crisis management has affected public support in the democratic backsliding members of the EU – Poland and Hungary. We claim the first, immediate effect of the pandemic is to “rally around flag” but since populist illiberal governments adopt authoritarian measures, the ongoing pandemic brings to the fore populists\u27 failure/ineffective crisis management, and thus public dissatisfaction should erode support for the incumbents. Relying on original survey data collected during the Covid-19 pandemic, we test several possible sources of dissatisfaction: the state of the healthcarethe economycorruption and abuse of powerand distorted communication/false information on the crisis. Citizens dissatisfied with governing populist parties’ performance should be willing to punish the “guilty” party withdrawing their support, yet we find partisan preferences affect government accountability evaluations and leave supporters immune to policy negative effects. Comparing Hungary to Poland, we see the more polarized society is, the more likely extraordinary circumstances will only reinforce divisions in society and strengthen incumbents.V prispevku analiziramo kako je krizno upravljanje med pandemijo covid-19 vplivalo na javno podporo v demokratično nazadujočih članicah EU – Poljski in Madžarski. Trdimo, da je prvi, takojšnji učinek pandemije "združevanje okoli zastave", toda ker populistične neliberalne vlade sprejemajo avtoritarne ukrepe, pandemija postavlja v ospredje neuspeh populistov in neučinkovito krizno upravljanje, zato bi moralo nezadovoljstvo javnosti zmanjšati podporo politike, ki je na oblasti. Na podlagi izvirnih anketnih podatkov, zbranih v času pandemije covid-19, testiramo več možnih virov nezadovoljstva: stanje v zdravstvu, gospodarstvo, korupcija in zloraba oblasti in izkrivljena komunikacija oziroma lažne informacije. Državljani, ki so nezadovoljni z delovanjem vladajočih populističnih strank, bi morali biti pripravljeni kaznovati "krivca", vendar ugotavljamo, da strankarske preference vplivajo na ocene odgovornosti vlade in puščajo podpornike imune na negativne učinke politike. Če primerjamo Madžarsko s Poljsko, vidimo, da bolj kot je družba polarizirana, večja je verjetnost, da bodo izredne okoliščine okrepile delitve v družbi in s tem tudi obstoječe oblasti
Onkraj etničnega preseganja
No full textThis study investigates how electoral system design shapes intra- ethnic competition, focusing on Iraqi Kurdistan from 1992 to 2013. Challenging Horowitz’s outbidding model, which assumes that ethnic parties escalate demands to outcompete rivals, this research demonstrates that electoral rules—including thresholds, ballot structures, and district demographics—mediate party strategies. Through mixed-methods analysis of elections, party platforms, and campaign materials, the findings reveal that high thresholds incentivize coalition-building, while their absence enables narrower appeals. Similarly, heterogeneous districts encourage inclusive strategies targeting diverse electorates, while homogeneous districts promote exclusivist appeals. The study concludes with actionable recommendations for electoral system design to balance inclusivity, stability, and representation in divided societies.Članek analizira vpliv zasnove volilnega sistema na znotrajetnično politično konkurenco, s posebnim poudarkom na primeru iraškega Kurdistana v obdobju 1992–2013. Študija izpodbija Horowitzov model »draženja«, ki predpostavlja, da etnične stranke stopnjujejo svoje zahteve z namenom prehiteti etnične tekmece. Nasprotno avtor ugotavlja, da so strategije političnih strank v večji meri oblikovane z volilnimi pravili – vključno z volilnimi pragovi, strukturo glasovnic in demografskimi značilnostmi volilnih okrožij. Z uporabo mešanih metod, ki vključujejo analizo volilnih rezultatov, programov političnih strank in kampanjskih gradiv, študija pokaže, da visoki volilni prag spodbuja oblikovanje predvolilnih koalicij, medtem ko njegova odsotnost omogoča polarizirane in partikularne nagovore volilcev. Podobno heterogena volilna okrožja spodbujajo vključujoče, široko usmerjene kampanje, medtem ko homogena okrožja krepijo ekskluzivistične, etnično usmerjene strategije. Študija se zaključi s praktičnimi priporočili za oblikovanje volilnih sistemov, ki naj bi v razdeljenih družbah uravnotežili cilje politične vključenosti, stabilnosti in reprezentativnosti
Roman coin finds from the “SNG Drama” site – Sector 1. Excavations in 2023–2024
No full textV magistrskem delu je obravnavan novčni zbir iz sektorja 1 na najdišču SNG Drama v Ljubljani, raziskovanem v letih 2023 in 2024. Najdišče se nahaja znotraj emonskega obzidja, v bližini foruma. Skupaj je bilo odkritih 474 novcev, ki so bili preliminarno očiščeni in dokumentirani. Večina novcev je rimskih, njihova opredelitev pa je temeljila na katalogih Roman Imperial Coinage.
Najstarejši primerek je noriški srebrnik iz 1. stoletja pr. n. št., najmlajšo skupino pa predstavljajo novci iz prve polovice 5. stoletja. Obdobje republike je odsotno, principat je zastopan skromno, dominat pa izredno močno. Še posebej izstopa številnost bronastih novcev iz druge polovice 4. stoletja, ki kažejo na okrepljen denarni obtok v zadnjih desetletjih pred propadom Emone. V obtoku so takrat hkrati krožili tudi starejši primerki, med njimi celo posamezen noriški novec. Največji delež predstavlja denar, kovan v Sisciji in Akvileji.
Zbir iz sektorja 1 se dobro ujema s splošnimi trendi v Emoni. Primerjalno nekoliko večjo količino poznorimskih novcev povezujemo s poslovanjem delavnice, ki je v tem času delovala na območju. Novci odražajo razvoj mesta od začetkov do njegovega poznega razcveta in konca v prvi tretjini 5. stoletja.This master’s thesis examines a coin assemblage from Sector 1 at the SNG Drama site in Ljubljana, excavated between 2023 and 2024. The site is located within the walls of Roman Emona, near the forum. A total of 474 coins were discovered, which were preliminarily cleaned and documented. Most of the coins are Roman, identified with the help of the Roman Imperial Coinage catalogues.
The earliest specimen is a small Noricum silver coin from the 1 st century BC, while the latest coins belong to the first half of the 5th century AD. Republican issues are absent, the Principate is only modestly represented, whereas the Dominate is strongly attested. Particularly prominent are the bronze issues of the second half of the 4th century, reflecting intensified monetary circulation in the final decades before the collapse of Emona. At that time, older coins also remained in use, including even an isolated Noricum specimen. The largest share of the assemblage derives from the mints of Siscia and Aquileia.
The Sector 1 assemblage largely corresponds to the general trends observed in Emona. Stronger representation of the late Roman coins is linked to the workshop that operated in
this area during that time. Overall, the coins reflect the development of the city from its early stages to its late flourishing and decline in the first third of the 5th century AD
The relationship between attachment styles, belief in the existence of God, spirituality, and attitudes toward celebrities in emerging adults
No full textMladi pogosto razvijejo tesne parasocialne odnose, kot so npr. odnosi s slavnimi osebami. Ti odnosi so enostranski, a pogosto zelo intimni. V raziskavi, v kateri je sodelovalo 182 mladih, starih od 18 do 30 let, smo preučili, koliko so ti odnosi povezani s slogom njihove navezanosti, prepričanostjo v obstoj Boga in duhovnostjo. Pričakovali smo, da slog navezanosti, verovanje v Boga in duhovnost pomembno napovedujejo parasocialne odnose. Za raziskavo smo prevedli in prilagodili naslednje ocenjevalne lestvice: Mladostnikova romantična parasocialna navezanost, Odnos do slavnih, Vprašalnik medosebnih odnosov, Lestvica prepričanj o obstoju Boga in Lestvica duhovne usmerjenosti. Med preučenimi slogi navezanosti sta le preokupirani/ambivalentni slog navezanosti in prepričanost v obstoj Boga značilno pozitivno napovedovala romantično parasocialno navezanost mladih na prehodu v odraslost ter njihov odnos do slavnih oseb. Višja raven duhovnosti je prav tako značilno napovedovala romantično parasocialno navezanost, ne pa tudi dosežka na lestvici intenzivnejšega odnosa do slavnih oseb. Rezultati podpirajo ugotovitve predhodnih študij o povezanosti med slogi navezanosti in parasocialnimi odnosi ter jih razširjajo z ugotovitvami, povezanimi z verovanjem v Boga in duhovnostjo. Kaže se potreba po nadaljnjem razvoju pripomočkov za preučevanje parasocialnih odnosov in duhovnosti.Young people often develop close parasocial relationships, such as celebrity relationships. These relationships are one-sided, but often very intimate. In a research involving 182 young people aged 18 to 30, we examined how these relationships are related to their attachment style, belief in the existence of God, and spirituality. We expected that attachment style, belief in God, and spirituality significantly predict parasocial relationships. We translated and adapted the following rating scales for the research: Adolescent Romantic Parasocial Attachment, Celebrity attitudes, Relationship Scales Questionnaire, Existence of God Scale, and The New Age Orientation Scale. Among the attachment styles studied, only the preoccupied/ambivalent attachment style and the belief in the existence of God significantly positively predicted the romantic parasocial attachment of young people at the transition to adulthood and their attitudes towards celebrities. Higher levels of spirituality also significantly predicted romantic parasocial attachment, but not achievement on the scale of intense celebrity relationship. The results support the findings of previous studies on the association between attachment styles and parasocial relationships and extend them with findings related to belief in God and spirituality. There is a need for further development of instruments for the study of parasocial relationships and spirituality
