Analisis Model Newcomb, One-Step Flow, dan Two-Step Flow dalam Proses Kampanye Digital Pilkada 2024 di Sumatera Utara
Authors: Silaen Mulkan Darajat , Kholil Syukur
Published: January 2025

This study aims to analyze the application of three communication models Newcomb, One-Step Flow, and Two-Step Flow  in the 2024 Regional Election digital campaign in North Sumatra. The method used is a qualitative approach with literature review, collecting secondary data from various related literature. Newcomb's model emphasizes the importance of interpersonal relationships in political communication, where potential leaders and voters must have the same attitude to increase the effectiveness of campaign messages. Through social media, these interpersonal relationships are built through two-way interactions that strengthen voter trust and loyalty. The One-Step Flow model, on the other hand, focuses on delivering a direct message from a candidate to an audience without traditional intermediaries. The use of platforms such as Instagram and Twitter allows potential leaders to convey messages quickly and responsively, especially to young voters who are more active in digital media. However, this model faces challenges in the dissemination of misinformation or manipulation of public opinion. The Two-Step Flow model underlines the important role of opinion leaders, such as influencers and community leaders, in filtering and disseminating campaign messages. They act as intermediaries who are able to bridge communication between prospective leaders and voters, provide more personalized interpretations, and increase voter participation. The results show that the combination of these three communication models forms a more holistic and adaptive digital campaign strategy. The proper use of social media, strong interpersonal interaction, and the involvement of opinion leaders can increase the effectiveness of campaigns, political participation, and a positive image of prospective leaders. This strategy is relevant in facing the diverse demographic and cultural challenges in North Sumatra, as well as helping to build the legitimacy of the candidates in the eyes of the public.
Collaborative Healthcare Data Management Framework using Parallel Computing and the Internet of Things
Authors: D Shamia , M Ephin , Yalagi Pratibha C. Kaladeep , Chowdhury Rini , Prashant Kumar  , R Prabhu
Published: January 2025

Healthcare data management has become a critical research area, primarily driven by the widespread adoption of personal health monitoring systems and applications. These systems generate an immense volume of data, necessitating efficient and reliable management solutions for lossless sharing. This article introduces a Collaborative Data Management Framework (CDMF) that leverages the combined strengths of parallel computing and federated learning. The proposed CDMF is designed to achieve two primary objectives: reducing computational complexity in data handling and ensuring high sharing accuracy, regardless of the data generation rate. The framework employs parallel computing to streamline the scheduling and processing of data acquired at various intervals. This approach minimizes processing delays by operating on a less complex scheduling algorithm, making it suitable for handling high-frequency data generation. Federated learning, on the other hand, plays a pivotal role in verifying data distribution and maintaining sharing accuracy. By enabling decentralized learning, federated learning ensures that data remains on local devices while sharing only the necessary model updates. This approach enhances privacy and security, a critical consideration in healthcare data management. It ensures that data distribution and sharing are verified based on appropriate requests while avoiding latency issues. By decentralizing the learning process, federated learning enhances privacy and security, as raw data does not leave the local systems. This cooperative interaction between parallel computing and federated learning operates in a cyclic manner, allowing the framework to adapt dynamically to increasing monitoring intervals and varying data rates. The performance of the CDMF is validated through improvements in two key metrics. First, the framework achieves a 15.08% enhancement in sharing accuracy, which is vital for maintaining data integrity and reliability during transfers. Second, it reduces computation complexity by 9.48%, even when handling maximum data rates. These results highlight the framework’s potential to revolutionize healthcare data management by addressing the dual challenges of scalability and accuracy.
The complex world of additives: metabolic implications and more. A new risk factor for the onset of type 2 diabetes?
Authors: Rocca, A.
Published: January 2025

Il consumo di alcuni additivi alimentari (in particolare gli emulsionanti) è stato da tempo associato ad un aumentato rischio di sviluppare malattie croniche (obesità, problematiche cardio-vascolari e cancro). L’analisi del recente Studio di Coorte Nutri-Net-Santé, svoltosi in Francia fra il 2009 ed il 2023, suggerisce inoltre che possa esserci un collegamento anche con la comparsa del diabete. Sono stati raccolti, con un’indagine prospettica, i diari alimentari di 104.139 partecipanti volontari (79% donne), che contenevano indicazioni su quantità di consumo e marca dei prodotti di un’ampia gamma di alimenti “ultra-processati” (cioccolato, gelati, biscotti, pasticcini, prodotti ortofrutticoli e cereali trasformati, prodotti lattiero-caseari, maionese, oli commestibili e sciroppi). L’analisi statistica complessiva dei dati raccolti, su 61 sostanze valutate, ha suggerito che un’assunzione più elevata di 7 gruppi di emulsionanti (E407, E340, E472e, E331, E412, E414, E415) possa essere associata ad un aumentato rischio di sviluppare diabete di tipo 2 (1.056 casi diagnosticati, pari all’1,01% del campione: percentuale non molto elevata, considerando la prevalenza del diabete tipo 2 e la durata dello studio). Le maggiori fonti di consumo di questi emulsionanti sono comprese in: frutta e verdure ultra-processate (nel 18.5% dei casi - alimenti in scatola/sciroppati); torte e biscotti (nel 14%); prodotti lattiero-caseari (nel 10%), prodotti spesso considerati parte di un’alimentazione sana. Questi dati, se confermati da ulteriori studi, potrebbero avere importanti implicazioni per la salute pubblica. È comunque utile limitare il più possibile il consumo di alimenti ultra-processati, imparando a trarre importanti informazioni nutrizionali dalla lettura delle etichette degli alimenti. PAROLE CHIAVE alimenti ultraprocessati; additivi alimentari; emulsionanti; Coorte Nutri-Net Santé; diabete tipo 2.

Twenty-eight (77.1%) patients wanted a combination of print and digital information. Conclusion: In summary our short-term results show a strong increase of information dissemination and - as an effect - a high patient satisfaction and benefit mediated by the app. Key words: Fast track, smartphone, arthroplasty, application, hip, knee
Volume-controlled ventilation with Breas LTV 1000 ventilators under hypobaric conditions. A lung simulator analysis.
Authors: Schedler Olaf , Hensel Mario , Stein Eberhard , Miosga Johannes
Published: January 2025

The successful functioning of ventilators under varying ambient conditions depends strongly on barometric pressure and gas density. We examined volume-controlled ventilation using the LTV 1000 Breas ventilator under hypobaric conditions in a typical high altitude profile. The LTV 1000 ventilator administers significantly higher tidal volumes at altitudes above 5000 feet (PBARO=633 mmHg), surpassing the reference ranges (VT ±10%) of all selected tidal volumes. The mean volume increase was 235±66 mL for VT=500 mL, 296±83 mL for VT=700 mL and 414±77 mL for VT=1000 mL. The reason for this lies in the physical changes defined by Boyle’s Law, which lead to volume expansion at low pressure and faulty flow measurements of expiratory volumes due to changes in gas density. Appropriate monitoring is thus recommended when using the LTV 1000 ventilator in volume-controlled ventilation mode under varying ambient conditions above 5000 feet. The analysis produces a reference value for the reduction in the ground normal tidal volume of 3% per 1000 feet.

Nichtinvasive Herzzeitvolumenmessung assistiert und spontanatmender Patienten mittels partieller CO2 Rückatmung.
Authors: Schedler Olaf
Published: January 2025

Bei der Methode der partiellen Kohlendioxidrückatmung verhält sich das Herzzeitvolumen (HZV) proportional zur Veränderung der CO2 Eliminierung, dividiert durch die Veränderung des endtidalen CO2, als Folge einer Rückatmungsperiode. Dieses Messprinzip machte bislang die konkrete Bestimmung der HZV in vergangenen Untersuchungen unter Spontanatmung und assistierter Spontanatmung unmöglich. Vorteile von NICO™ gegenüber invasiver Methoden bestehen in der kontinuierlichen Messung endtidaler CO2 Konzentrationen und der daraus resultierenden Möglichkeit der Bestimmung der Totraumventilation (VD/VT), der alveolären Ventilation (MValv), der Messung des effektiven pulmonalen. Blutflusses (PCBF) sowie der Ermittlung der VCO2.und VO2. Für die Untersuchung wurden 45 intensivpflichtigen Patienten mit vorhandenem invasiven Monitoring (PiCCO, CCO) und assistierter Beatmung (BIPAP ASB, SIMV) oder assistierter Spontanatmung (ASB, CPAP) über einen liegenden endotrachealen Tubus, rekrutiert. Die Bereitstellung des NICO™ Monitoring mit NICO CO2 Loop Flowsensor, NICO Sensor mit Rückatmungsventil und Monitor erfolgte durch Firmen hesto med Lichtenstein und Respironics® Deutschland. Gleichzeit wurden die Mikrozirkulationsparameter (SO2, Flow, Velocity) in 3 und 7 mm Gewebetiefe mittels LEA O2C Laserdopplerflowspektrometrie gemessen. Das mittels CO2 Rückatmung ermittelte Herzzeitvolumen korreliert mit dem invasiv bestimmten Herzzeitvolumen (6,15±1,83 l/min vs. 6,73±1,70 l/min; Pearson=0,66, R2= 0,43; p>0,1). In Abbildung 1 werden die ermittelten Werte für das Herzzeitvolumen an 45 Einzelmessungen dargestellt. Die gemessene CO2 Abgabe korreliert mit dem endexspiratorischen Atemzugvolumen (268±68,08 ml vs.187,48±76,75 ml; Pearson =0,35; R2=0,13) und dem endexspiratorischen CO2 (32,74±5,02 mmHg; Pearson=0,45, R2=0,2) und ist abhängig vom Ventilations-Perfusions Mismatch (VQI =25,93±8,61%) und der Totraumventilation (TRV=58,8±49,29 ml). Die Faktoren der CO2 Produktion (VCO2) haben einen Einfluss auf die subkutane Sauerstoffsättigung (SO2P1S; Pearson=0,4) und auf den Blutfluss (Flow P1S) in 3 mm Gewebetiefe (Pearson= 0,5) sowie auf den Blutfluss (Flow P1D) in 7 mm Gewebetiefe (Pearson=0,3). Der pulmonalkapilläre Blutfluss (PCBF) besitzt eine negativ gerichteten Korrelation auf die subkutane Sauerstoffsättigung (SO2P1S; -0,3) sowie den Blutfluss (Flow P1D) in der Gewebeschicht von 7 mm (Flow; -0,4). Ein Einfluss des ermittelten Herzzeitvolumens zur Mikroperfusion findet sich nicht. Damit erweist sich das NICO CO2 Rückatmenverfahren als geeignetes Instrument zur kontinuierlichen Überwachung spontan oder assistiert atmender Patienten. Eine Korrelation der im NICO System ermittelten Parameter und den gemessenen Parameter der Mikrozirkulation (O2C) finden sich von VCO2 subkutaner Sauerstoffsättigung und Blutfluss sowie des pulmonalen Blutflusses (PCBF) zur subkutanen Sauerstoffsättigung und zum tiefen Gewebeblutfluss (FlowP1D).

Funktionsuntersuchungen der Mikrozirkulation mit Hilfe der Laser-Doppler-Flow-Spektrometrie (O2S)
Authors: Schedler Olaf
Published: January 2025

Zur lokalen Funktionsüberprüfung der Mikroperfusion hat sich die Okklusions- oder Ischämiemethode mit der Bestimmung der Durchblutung mit einer reaktiver Hyperämie als wertvoll erwiesen, da diese Reaktion unabhängig von neuralen Mechanismen funktioniert. Mit einer reaktiven postischämischen oder postokklusiven Hyperämie wird der Blutfluss und damit die Sauerstoffversorgung angepasst, was durch lokale Anhäufung humoraler Faktoren (Metaboliten) zu einer Perfusionssteigerung führt. Normalerweise steigt die Perfusion nach einer kurzen Okklusions- oder Ischämiezeit, durch eine myogene Reaktion der Gefäßwand, auf einen vorrübergehenden höheren Ausgangswert, um nach einigen Minuten das vorbestehende Niveau wieder zu erreichen. Bei längerdauernder Ischämie aktiviert der Abfall des Sauerstoffpartialdrucks diese Reaktion und es dominiert die Bildung von Stickstoffmonoxid. Lokale oder globale Steigerungen der metabolischen Aktivität bedingen eine reaktive Beeinflussung des kapillären Blutflusses. Dabei ist die zelluläre Sauerstoffmetabolisierungsrate ein wichtiger Indikator für die Integrität des betreffenden Gewebes. Basierend auf dem Fick´schen Prinzip kann der globale Sauerstoffmetabolismus mithilfe der arteriovenösen Sauerstoffsättigung (AvDO2) und des Blutflusses, nach einer grundsätzlichen Gleichung berechnet werden.
Normwertbestimmung von mikrozirkulatorischen Parameter.

In der Bestimmung der Werte aus den Mikrozirkulationsmessungen mittels Gewebespektrometrie (O2S) liegen bisher keine Normwerte vor, welche bezogen auf das zu untersuchende Organ als Interpretationshilfe verwendet werden können. Auf Grund lokaler, regionaler, organspezifischer und gravitationsabhängiger Perfusion ist die Beurteilung der Mikrozirkulation im kapillären Stromgebiet multifaktoriell beeinflusst. An einer gesunden Probandengruppe wurden Messwerte an unterschiedlichen Referenzpunkten vorgenommen. In den Ergebnissen zeigen wir für Referenzmessorte Normwerte und ihrer Normalwertebereiche auf und korrelierten diese Werte mit verfügbaren klinischen Parametern der Perfusion und des zellulären Metabolismus. Es konnte gezeigt werden, dass ein guter Interpretationszusammenhang zwischen der relativen Sauerstoffsättigung und dem relativen Sauerstoffmetabolismus besteht. Diese positive Konstellation findet man auch zwischen relativer Hämoglobinkonzentration und der Sauerstoffextraktionsrate wieder.
Physikalische Prinzipien der Laser-Doppler-Flowspektrometrie – O2 to See (O2S).

Die Laserdopplerflowmetrie wird durch einen Diodenlaser von einer Halbleiterdiode mit 830 nm und einer Leistung von bis zu 30 mW im continuous wave Modus (CW) zur Generierung von Licht im Nahinfrarotbereich realisiert. Der Dopplereffekt beschreibt das Ausmaß der Frequenzverschiebung und hängt dabei von der Anzahl und Geschwindigkeit der das Laserlicht streuenden Körper ab. Die in Hertz (Hz) registrierte Frequenzänderung des Dopplersignals ist proportional zur Geschwindigkeit der strömenden Körper. Dabei wird die Anzahl der Körper und Geschwindigkeit der bewegten Körper registriert und der Fluss in der Mikrozirkulation berechnet. Der Flow ergibt sich aus der Geschwindigkeit (V) multipliziert mit der Anzahl der bewegten Körper mit deren Geschwindigkeit (N) über allen zu beobachtenden Körpergeschwindigkeiten (?). Die Weißlichtquelle wird von einer 20 Watt Halogenlampe mit einem Wellenbereich zwischen 450-1000 nm gebildet. Das Messprinzip beruht auf die gewebespezifische Absorption und Reflektion der emittierten Lichtquanten. Besonders die Streuung an der mitochondrialen Matrix bedingt eine veränderte Lichtausbreitung. Mithilfe der eindeutigen Farbkodierung des jeweiligen Oxygenierungszustandes kann von der detektierten Blutfarbe auf die Sauerstoffsättigung des Blutfarbstoffes geschlossen werden. Dies gelingt durch die Berechnung des Farbspektrums anhand der absorptionsbedingten Verschiebung in den einzelnen Wellenlängenbereichen des Lichts. Durch Abgleich der detektieren Hämoglobinspektren der Mikrozirkulation mit experimentell ermittelten Referenzwerten der verschiedenen Absorptionsbereiche kann die Sauerstoffsättigung in Prozent ermittelt werden.

A lehetetlenség kategóriájának politikai ontológiai jelentőségéről Giorgio Agamben filozófiájában
Authors: Ilyés Zalán-György
Published: January 2025

Dolgozatom kiindulópontjául az az agambeni gondolat szolgál, miszerint „[a]míg a lehetőség új és koherens ontológiája nem kerül a tettre és annak a lehetőséghez való viszonyára alapított ontológia helyére […], addig a szuverenitás apóriájától mentes politikai elmélet elképzelhetetlen marad”. Ha ma, a Homo Sacer című főművének megírása után szinte harminc évvel úgy gondoljuk, Agamben megállapítása helyes és az általa kitűzött feladat vállalandó, tisztáznunk kell, hogy a filozófus meddig jutott e politikai elmélet elgondolásában. Ahhoz azonban, hogy ezt megtegyük, előbb arra a kérdésre kell választ találnunk, hogy sikerült-e kidolgoznia egy, a célnak megfelelő, „új és koherens” lehetőségontológiát, és ha igen, ez az ontológia hogyan működik. Bár terjedelmi okokból eme ontológia működésének maradéktalan feltérképezésére nincs lehetőségünk, kiemelhetjük néhány fontosabb elemét, a tisztánlátás reményében. Dolgozatomban amellett érvelek, hogy a lehetetlenség kategóriája kulcsfontosságú jelentőséggel bír Agamben politikai ontológiájában, hisz azon túl, hogy lehetővé teszi a lehetőség kategóriájának önmagában és önmagaként való megragadását (s ezáltal radikálisan kétségbe vonja az aktualitás primátusát), eszközül szolgál a megvalósulás eseményének radikális újragondolásához. Ahogy azt tanulmányom elején is megjegyzem, dolgozatom írása során igyekeztem szem előtt tartani Agamben tulajdonképpeni célját, így értekezésem politikai filozófiai kontextualizálása mellett a lehetetlenség kategóriájának esztétikai, etikai és politikai implikációira is reflektálok.
Jean-Luc Nancy, a politikai nyomkövetője
Authors: Kiss Lajos András
Published: January 2025

Az 2021-ben elhunyt francia filozófus, Jean-Luc Nancy életművében a politikai közösség meghatározásának dilemmái központi helyet foglalnak el. Nancy, elsősorban Bataille és Blanchot megfogalmazásához csatlakozva a „használati utasítás nélküli negativitás” sejtelmes szókapcsolatával írja le a maga sajátos közösségfelfogását. A szerző szerint az emberi közösség lényegének fogalmi definiálása szinte lehetetlen vállalkozás, mivel az - sajátos dinamizmusából fakadóan - a tárgyi megragadhatóságon túl helyezkedik el. A totalitárius rendszerek, illetve a liberál-kapitalista szisztéma egyaránt az „immanens” közösségek világát szeretnék megteremteni: az első változat egy kizárólagos, transzcendens elvre támaszkodva homogén, organikus társadalomtestet szándékozik megvalósítani, míg a másik változat az individuumot, a felbomlott közösségek maradékát, illetve reziduumát tekinti a „közösség” fundamentumának. Ugyanakkor Nancy szerint a lét (beleérve az emberi létet is) koegszisztenciális jellegű, nyitott, vagyis pluralista és sohasem „véglegesülő” fundamentumon nyugszik. A magányos létező önellentmondás.
Három világ
Authors: Ropolyi László
Published: January 2025

Széles körben elfogadott, hogy az univerzális internethasználat lényegesen befolyásolja az emberek életét. Az internetkutatásban elterjedt értelmezés szerint az internethasználat szükségszerű és változatos társadalmi és kulturális hatásokkal jár, s a feladat ezek feltárása, valamint kritikai értelmezésük révén a társadalmi és kulturális következmények azonosítása. Ezúttal azonban amellett érvelünk, hogy ennél többről van szó: nem pusztán a társadalom és kultúra átalakulása zajlik, hanem napjainkban alakul ki és ölt formát egy új emberi létezési mód. Az új emberi létmódot hálólétnek nevezzük és a korábban kibontakozott emberi létmódokra – a természetire és a társadalmira – ráépülő, harmadik létmódként azonosítjuk. Megállapítjuk, hogy az internethasználat következtében az ember immár a természeti, a társadalmi és a hálólét szféráit magában foglaló három létszféra/három világ polgára.
