Published: December 2023

Cel pracyIdentyfikacja kluczowych atrybutów myślenia cyfrowego oraz identyfikacja luk w zakresie cyfrowego sposobu myślenia, jakie obserwowane są w polskich przedsiębiorstwach.Materiał i metodyW pracy wykorzystano wyniki własnych badań ankietowych, które skupiały się na ocenie świadomości cyfrowej polskich przedsiębiorstw. Badania te zostały wykonane w okresie czerwiec-wrzesień 2023 roku na losowej próbie 1000 przedsiębiorstw.
W kontekście oceny stopnia zaawansowania myślenia cyfrowego w kwestionariuszu użyto 24 stwierdzeń, które respondenci oceniali w oparciu o 7-mio stopniową skalę Likerta.
Dane zbierano poprzez system CAWI w oparciu o kwestionariusz, w którym respondenci reprezentujący firmy wyrażali swoje opinie dotyczące: własnego postępowania, stosunku przełożonych, a w efekcie i warunków jakie stworzyła firma dla podejmowania określonych działań.WynikiBadania empiryczne pozwoliły na stwierdzenie, że w polskich przedsiębiorstwach widoczne są luki w zakresie myślenia cyfrowego. Chociaż na tym etapie badań trudno określić ich poziom, stwierdzić można, że dotyczą wszystkich objętych badaniami obszarów. Są one jednak szczególnie niepokojące w zakresie: gotowości pracowników do akceptacji zmian, skłonności przedsiębiorstw do akceptacji ryzyka, oraz tworzenia warunków do samodzielnego a zarazem odpowiedzialnego działania.WnioskiŚwiadomość cyfrową utożsamiać można z kompetencjami cyfrowymi pod warunkiem rozszerzenia ich zakresu o kompetencje mentalne, a więc pewne cechy osobowościowe czy dyspozycje behawioralne. U podstaw tak rozumianych kompetencji leży sposób myślenia cyfrowego, które jest ukierunkowane na rozwój. To w perspektywie firmy wymusza m.in.: myślenie w kategoriach wartości klienta, otwartość na współpracę, gotowość uczenia się i zdobywania doświadczeń, odwagę działania, czy innowacyjność.
Citizen Development als Treiber der digitalen Transformation – Aktuelle Ansätze bei der Adoption von Low-Code Development Plattformen
Authors: Prinz Niculin , Huber Melanie , Riedinger Constanze , Rentrop Christopher 
Published: December 2023

ZusammenfassungLow-Code Development Plattformen (LCDPs) fördern die digitale Transformation von Organisationen, indem sie die Applikationsentwicklung durch FachbereichsmitarbeiterInnen ohne tiefgreifende Programmierkenntnisse – sogenannte Citizen Developer – ermöglichen. Marktforschungsinstitute prognostizieren, dass in den nächsten Jahren mehr als die Hälfte aller Applikationen mit LCDPs entwickelt werden. Nichtsdestotrotz stehen Organisationen vor der Herausforderung, sich für die richtigen Implementierungs- und Anwendungsansätze von LCDPs zu entscheiden. Dieser Artikel liefert daher ein umfassendes Bild über das praktische Verständnis und aktuelle Ansätze in verschiedenen Organisationen und leitet daraus Handlungsempfehlungen ab. Dafür wurden 16 Experteninterviews durchgeführt und wissenschaftlich analysiert. Die Ergebnisse zeigen, dass die Praxis grundsätzlich ein ähnliches Verständnis des Begriffs LCDP hat. Die Initiative für die Einführung kommt meist aus den Fachbereichen, die Entscheidung für oder gegen die LCDP-Implementierung wird jedoch meist von der Geschäftsführung in Kooperation mit der IT-Abteilung getroffen. Dabei unterscheiden sich die aktuellen Anwendungsansätze: Unternehmen nutzen entweder einen Self-Service-Ansatz durch die Fachbereiche oder integrieren die Entscheidung über eine potenzielle LCDP-Entwicklung durch die Citizen Developer in das bestehende Demand-Management der IT-Abteilung. Eine etablierte und adaptive Governance ist für beide Ansätze eine wichtige Voraussetzung. Die Erkenntnisse des Beitrags tragen zur wissenschaftlichen Diskussion bei, da dieser Artikel eine der ersten umfassenden und wissenschaftlich fundierten qualitativen Analysen über aktuelle praktische Adoptionsansätze der Praxis liefert. PraktikerInnen erfahren zudem, wie andere Unternehmen mit aktuellen Herausforderungen umgehen und welche Ansätze erfolgversprechend sind.
Digitale Kompetenzanforderungen in der öffentlichen Verwaltung nach der COVID-19-Pandemie
Authors: Auth Gunnar , Bensberg Frank , Christ Julian P. 
Published: December 2023

ZusammenfassungDigitale Kompetenzen haben sich spätestens seit den COVID-19-bedingten Lockdowns sowie auch im Kontext von New Work und KI-Anwendungen zu einem zentralen Aktionsfeld für Wirtschaft, Wissenschaft und Politik entwickelt. Die öffentliche Verwaltung befindet sich seit einigen Jahren in einer verstärkten strukturellen und technischen Transformation, hin zu einer digitalisierten und modernen Verwaltung, welche einen tiefgreifenden Auf- und Umbau von Kompetenzanforderungen bedingt. Dies führt zu massiven Veränderungen von Kompetenzprofilen und Stellenanforderungen auf Ebene der Kommunen, der Länder und des Bundes. Relevanz und Bandbreite digitaler Kompetenzen für E‑Government wurden bereits in mehreren Studien untersucht, wenngleich generalisierbare empirische Analysen noch am Anfang stehen. Unmittelbar vor Ausbruch der COVID-19-Pandemie führten die Autoren im Zeitraum von Dezember 2019 bis März 2020 eine Erhebung digitaler Kompetenzanforderungen in Stellenanzeigen der öffentlichen Verwaltung durch. Den Bezugsrahmen für diese quantitative Untersuchung bildete ein eigens entwickeltes komplementäres Modell digitaler Kompetenzen inkl. einer zweckgerichteten Operationalisierung. In diesem Beitrag werden auf Basis eines quantitativen Ansatzes Stellenanzeigen der öffentlichen Verwaltung aus dem Jahr 2023 großzahlig analysiert und mit der Referenzauswertung der Prä-Corona-Datenerhebung aus 2019/2020 verglichen. Als Datengrundlage dienen elektronische Stellenanzeigen, die automatisiert aus dem zentralen Stellenportal des Bundes extrahiert wurden. Hierdurch wird folgende Forschungsfrage beantwortet: Welche Veränderungen digitaler Kompetenzanforderungen in Folge der COVID-19-Pandemie lassen sich in Stellenanzeigen der öffentlichen Verwaltung identifizieren?
Internet of Things (IoT) about Disabilities
Authors: Al-karawi Khamis  A. 
Published: December 2023

The Internet of Things (IoT) holds significant promise for enhancing the lives of individuals with disabilities. By integrating smart devices and technologies, the IoT offers innovative solutions to address various challenges faced by people with disabilities and promote inclusivity. It is striking that more than one billion individuals, encompassing adults and children, live with disabilities, constituting roughly 15% of the world's total population. This highlights the significant impact and importance of addressing issues related to disability inclusivity and support globally. Unfortunately, the lack of support services often results in disabled individuals becoming overly reliant on their families, leading to economic inactivity and social exclusion.
Nevertheless, the Internet of Things (IoT) holds promise in offering essential aid and encouragement, empowering them to enhance their quality of life and engage more actively in societal and economic spheres. This article explains how the Internet of Things can benefit individuals with disabilities. We introduce the suggested IoT framework to realize this goal, highlighting the interplay between its diverse components. We delve into distinct application scenarios to demonstrate how the IoT can address the unique requirements of people with disabilities. Moreover, this paper addresses critical challenges to be acknowledged and overcome when implementing IoT-based solutions.

Published: December 2023

Occlusion of a large cerebral artery in ischemic stroke (IS) is associated with a high mortality rate. Despite the results of studies that have demonstrated the beneficial effect of endovascular therapy on functional outcome in IS, little research has been conducted on its impact on hospital mortality in IS, its timing and structure.Objective: to investigate hospital mortality in patients with IS and large cerebral artery occlusion, who underwent mechanical thrombectomy (MTE).Material and methods. The retrospective study included data from 233 patients with IS and confirmed occlusion of a large cerebral artery (internal carotid artery, M1 and M2 segments of the middle cerebral artery, basilar artery) treated at the regional vascular center V.V. Veresaev Hospital, Moscow, 2018 and 2022. A comparison of hospital mortality in the group of patients who underwent MTE and the group of patients who received basic therapy was performed.Results. MTE was performed in 107 patients (46%); 126 patients (54%) received only basic therapy. The mortality rate of all patients included in the study was 44.2%. Among all deaths, the proportion of patients with MTE was only 7.2%, while the proportion of patients on basic therapy was 36.9% (p<0.001). Mortality in the MTE group was four times lower than in the basic therapy group – 15.8% compared to 68.2% (p<0.001). We observed that certain manifestations were significantly more frequent in the basic therapy group: cerebral edema (42% vs. 18.6%), hemorrhagic transformation (19.9% vs. 12.9%), venous thromboembolism (6.3% vs. 3.7%) and infectious complications (42.8% vs. 14.3%). The mortality of patients in the basic therapy group was higher on the first day, on days 2–3 and also on days 4–7, while no differences in mortality were observed after the first week of the disease.Conclusion. Admission of a patient with IS within the “therapeutic window” creates the conditions for a significant reduction in hospital mortality and the incidence of stroke complications.

Published: December 2023

Histologically, chronic demyelinating lesions in multiple sclerosis (MS) have been shown to include inactive lesions that do not change over time and active or “smouldering" lesions that tend to enlarge over time and are surrounded by pro-inflammatory activated microglial cells that are loaded with iron. To identify “smouldering" foci of demyelination and assess the “latent” inflammatory process in the brain, MRI sequences sensitive to the detection of substances with paramagnetic properties, including iron, must be used. They include an innovative technique such as quantitative susceptibility mapping (QSM).Objective: to identify, using MRI different types of chronic demyelination foci in MS, based on iron distribution and the degree of damage (myelination) in their structure.Material and methods. The patterns of iron distribution in demyelinating lesions in 90 MS patients were investigated using QSM. In addition, two lesions with different iron distribution patterns were randomly selected on the QSM map for each patient, in which the magnetic transfer ratio (MTR), indirectly reflecting the degree of myelination, was calculated. The identified changes were also compared with visualization of lesions in standard MRI modes (T1 MPRAGE, T2 FLAIR).Results. Despite the predominantly identical visualization in T2 FLAIR mode, chronic foci of demyelination show different patterns on the QSM maps, which is due to the peculiarities of iron distribution: some foci are not detected on QSM, while others are visualized either in the form of a homogeneous or a ring-shaped pattern. When comparing QSM data with MTR, it was found that MTR indicators were highest in non-visualized lesions (demyelination is minimal), while damage was most pronounced in lesions with ring-shaped iron distribution.Conclusion. Different patterns of iron distribution in demyelination foci compared to the degree of myelination in these foci according to MTR were identified using QSM, which is of great importance for the evaluation of latent inflammation and the development of the neurodegenerative process in MS.

Published: December 2023

Uvod: Nagel tehnološki razvoj v zdravstvu neposredno vpliva na zdravstveno nego in na poklic medicinske sestre in zdravstvenika. Manko znanja med medicinskimi sestrami o raznolikih novih tehnologijah v zdravstvu predstavlja izziv na področju zdravstvene nege in kakovostne oskrbe pacientov. Namen raziskave je bil ugotoviti, v kolikšni meri so vsebine s področja pametnih tehnologij vključene v visokošolsko izobraževanje bodočih diplomiranih medicinskih sester v Sloveniji.Metode: Zbiranje učnih načrtov prek spletnih strani osmih visokošolskih institucij in osebnega stika s fakultetami in nosilci posameznih predmetov je potekalo v januarju in februarju 2023. Analizirali smo dvajset učnih predmetov, ki so ustrezali vključitvenim kriterijem. Uporabili smo kvalitativni raziskovalni način z eksplorativno metodo, ki smo jo združevali z elementi vsebinske analize in vizualizacijske metode.Rezultati: V učnih načrtih predmetov s področja informatike in informacijsko komunikacijskih tehnologij (IKT) smo prepoznali šest vsebinskih sestavnih delov: pametne tehnologije, osnove IKT in informatike, IKT v zdravstvenem izobraževanju, IKT v zdravstvu, e-zdravje in druge vsebine s področja IKT. Pametne tehnologije so redko vključene v predmete na prvi in na drugi stopnji izobraževanja v zdravstveni negi.Diskusija in zaključek: V učnih programih slovenskih visokošolskih zavodov s področja zdravstvene nege močno primanjkuje vsebin s področja pametnih tehnologij. Glede na naglo širjenje digitalizacije v zdravstvu in pomembno vlogo medicinskih sester pri uvajanju in uporabi te vrste tehnologij v praksi bi bilo v prihodnje treba narediti korak naprej in v učne načrte visokošolskih institucij na področju zdravstvene nege ter v dodatna usposabljanja za medicinske sestre vključiti več poglobljenih vsebin s tega področja in jih tako obogatiti z naprednimi znanji in spretnostmi.

Fatty acid composition of eggs enriched with omega –3 fatty acids on the market
Authors: STIBILJ Vekoslava , KOMAN RAJŠP Mojca , HOLCMAN Antonija 
Published: December 2023

The aim of our work was to determine fatty acid content in eggs enriched with omega-3 polyunsaturated fatty acids from various producers on the market. Due to simplicity, speed and reduced organic solvent usage, we used the in situ trans-esterification ISTE method for the determination of the fatty acid composition in eggs. The method was checked by the analysis of certified reference material CRM 164 (Anhydrous Milk Fat). The analytical results are in good accordance with certified values. The obtained results show that enriched eggs have a better fatty acid composition than average table eggs, regardless the producer. The ratio of FAs w -6 to w -3 in enriched eggs is less than 5, being 10 in ordinary eggs. An approximately equal content of alpha linolenic acid (18:3, n-3) was found in the enriched eggs from Jata Reja and Maia, 1.29 wt % and 1.25 wt % respect., while it was 11.28 wt % in the Fisher-Weppler’s eggs. The comparison of obtained results, the fatty acid content per 100 g egg content, with literature data is quite difficult, because authors calculate the content of FA in various ways. According to recent data from the literature (Weihrauch et al., 1977, Guardiola et al., 1994, Fatty acids, 1998, Kunachowicz et al., 1998), we have chosen a conversion factor of 0.83 in order to calculate the total fatty acids content in a 100 g egg content. The producers should declare the fatty acid composition, i.e. the content of w -3 PUFA-s, EPA and DHA on the package so that consumers are informed about the nutritional value of the food.

Authors: RAJČEVIČ Marija , LEVSTEK Jože , RAJČEVIČ Uroš , ILC Tone 
Published: December 2023

On a farm with 230 Friesian cows, winter and summer nutrition of highly pregnant dry cows was studied. Dietary cation-anion difference in the rations (DCAD) was calculated to estimate its possible connection with the incidence of milk fever and hypocalcaemia in cows. In winter season daily ration was composed of 3 kg of hay, 10-13 kg of grass silage and 10-13 kg of maize silage, with 1 kg of concentrate and 50 g of min.-vit. mixture. During summer season cows grazed and were additionally fed 3 kg of hay and 8 kg of maize silage till mid June, then until the end of season the maize silage was replaced by 10 of grass silage. A week before expected date of calving, cows were fed an additional 2 kg of concentrate. Throughout the dry period the cows were also fed 100 g of min.-vit. mixture. Dietary cation-anion difference was estimated as milliequivalent (meq) per kg of DM [(K++Na+) – (Cl-+S--)] (Oetzel, 1993). In winter months (November-February) dietary cation-anion difference ranged from 365 to 373 meq kg-1 DM. In studied months of winter season 83 cows calved, 9 of which were treated for milk fever and 5 for hypocalcaemia. In summer season (May-September) dietary cation-anion difference ranged from 27 to 238 meq -1kg DM. In studied months of summer season 73 cows calved, 6 of which were treated for milk fever and 3 for hypocalcaemia.

Authors: ZOREC Maša , MARINŠEK-LOGAR Romana , ČEPELJNIK Tadej , NEKREP Franc V. 
Published: December 2023

Butyrivibria represent a significant proportion of bacterial isolates from different ruminants. The strain Butyrivibrio sp. Mz5 was originally isolated from the rumen of a black and white Frisian cow. It possesses very high xylanolytic activity, at least 1.65 times higher than any of the tested anaerobic bacteria, as shown earlier. The inducibility by substrate, the influence of substrate concentration and growth phase on expression of its endoxylanases were tested in the present work. Xylanase activity of Butyrivibrio sp. Mz5 was found to be inducible, the specific activity of cells grown on xylan being increased 34-fold in comparison with cells grown on soluble carbon sources. The 51 kDa- and 145 kDa-endoxylanases are constitutive. The highest xylanolytic activity was detected after 16 hours growth and at 0.5% xylan concentration in growth medium. The majority of the xylanolytic activity was cell bound. Lower concentrations of xylan promoted the release of xylanolytic enzymes into the medium. The 26.7 kDa endoxylanase showed resistence to lower pH. The data obtained will help to achieve maximal xylanolytic activity for the needs of enzyme purification.

Authors: LOGAR Betka , KOVAČ Milena 
Published: December 2023

V raziskavo je bilo vključenih 46 960 prasitev pri svinjah pasme švedska landrace (SL) in large white (LW) ter F1 križankah teh pasem, liniji 12 (SL x LW) in liniji 21 (LW x SL). S ponovljivostnim modelom živali smo analizirali število rojenih in število živorojenih pujskov od prve do šeste zaporedne prasitve. Razliko med posameznimi genotipi smo obravnavali v obliki parametrov križanj. Proučevali smo maternalne komponente: aditivni maternalni vpliv, maternalni heterozis in aditivni vpliv stare matere, ki so bile obravnavane kot neodvisne spremenljivke. Prispevek aditivnega maternalnega vpliva k razliki med pasmama (SL-LW) je bil večji za število živorojenih (0,36) kot za število rojenih pujskov (0,09). Oceni maternalnega heterozisa, ki pojasnjujeta odstopanje linij od povprečja pasem, sta za število rojenih pujskov 0,69 in 0,72 za število živorojenih pujskov v gnezdu. Razlika med linijama (SL x LW-LW x SL) je zanemarljiva (0,06 za rojene in –0,03 za živorojene pujske).
