Dry EEG measurement of P3 to evaluate cognitive load during sitting, standing, and walking
Authors: Swerdloff Margaret M. , Hargrove Levi J.
Published: July 2023

Combining brain imaging with dual-task paradigms provides a quantitative, direct metric of cognitive load that is agnostic to the motor task. This work aimed to quantitatively assess cognitive load during activities of daily living–sitting, standing, and walking–using a commercial dry encephalography headset. We recorded participants’ brain activity while engaging in a stimulus paradigm that elicited event-related potentials. The stimulus paradigm consisted of an auditory oddball task in which participants had to report the number of oddball tones that were heard during each motor task. We extracted the P3 event-related potential, which is inversely proportional to cognitive load, from EEG signals in each condition. Our main findings showed that P3 was significantly lower during walking compared to sitting (p = .039), suggesting that cognitive load was higher during walking compared to the other activities. There were no significant differences in P3 between sitting and standing. Head motion did not have a significant impact on the measurement of cognitive load. This work validates the use of a commercial dry-EEG headset for measuring cognitive load across different motor tasks. The ability to accurately measure cognitive load in dynamic activities opens new avenues for exploring cognitive-motor interactions in individuals with and without motor impairments. This work highlights the potential of dry EEG for measuring cognitive load in naturalistic settings.
Emotion dynamic patterns between intimate relationship partners predict their separation two years later: A machine learning approach
Authors: Hilpert Peter , Vowels Matthew R. , Mestdagh Merijn , Sels Laura
Published: July 2023

Contemporary emotion theories predict that how partners’ emotions are coupled together across an interaction can inform on how well the relationship functions. However, few studies have compared how individual (i.e., mean, variability) and dyadic aspects of emotions (i.e., coupling) during interactions predict future relationship separation. In this exploratory study, we utilized machine learning methods to evaluate whether emotions during a positive and a negative interaction from 101 couples (N = 202 participants) predict relationship stability two years later (17 breakups). Although the negative interaction was not predictive, the positive was: Intra-individual variability of emotions as well as the coupling between partners’ emotions predicted relationship separation. The present findings demonstrate that utilizing machine learning methods enables us to improve our theoretical understanding of complex patterns.
Efficacy and safety of non-pharmacological therapy under the guidance of TCM theory in the treatment of anxiety in patients with myocardial infarction: A protocol for systematic review and meta-analysis

Published: July 2023

Background

With the increasing pressures of modern life and work, combined with a growing older population, the incidence of comorbid anxiety and myocardial infarction (MI) is increasing. Anxiety increases the risk of adverse cardiovascular events in patients with MI and significantly affects their quality of life. However, there is an ongoing controversy regarding the pharmacological treatment of anxiety in patients with MI. The concomitant use of commonly prescribed selective serotonin reuptake inhibitors (SSRIs) and antiplatelet medications such as aspirin and clopidogrel may increase the risk of bleeding. Conventional exercise-based rehabilitation therapies have shown limited success in alleviating anxiety symptoms. Fortunately, non-pharmacological therapies based on traditional Chinese medicine (TCM) theory, such as acupuncture, massage, and qigong, have demonstrated promising efficacy in treating MI and comorbid anxiety. These therapies have been widely used in community and tertiary hospital settings in China to provide new treatment options for patients with anxiety and MI. However, current studies on non-pharmacological TCM-based therapies have predominantly featured small sample sizes. This study aims to comprehensively analyze and explore the effectiveness and safety of these therapies in treating anxiety in patients with MI.

Method

We will systematically search six English and four Chinese databases by employing a pre-defined search strategy and adhering to the unique rules and regulations of each database to identify studies that fulfilled our inclusion criteria, to qualify for inclusion, patients must be diagnosed with both MI and anxiety, and they must have undergone non-pharmacological TCM therapies, such as acupuncture, massage, or qigong, whereas the control group received standard treatments. The primary outcome measure will be alterations in anxiety scores, as assessed using anxiety scales, with secondary outcomes encompassing the evaluations of cardiopulmonary function and quality of life. We will utilize RevMan 5.3 to conduct a meta-analysis of the collected data, and subgroup analyses will be executed based on distinct types of non-pharmacological TCM therapies and outcome measures

Results

A narrative summary and quantitative analysis of the existing evidence on the treatment of anxiety patients with MI using non-pharmacological therapies guided by Traditional Chinese Medicine theory.

Conclusion

This systematic review will investigate whether non-pharmacological interventions guided by TCM theory are effective and safe for anxiety in patients with MI, and provide evidence-based support for their clinical application.

Simultaneous analytical method for 296 pesticide multiresidues in root and rhizome based herbal medicines with GC-MS/MS
Authors: Yang Seung-Hyun , Shin Yongho , Choi Hoon
Published: July 2023

A method for the simultaneous analysis of pesticide multiresidues in three root/rhizome-based herbal medicines (Cnidium officinale, Rehmannia glutinosa, and Paeonia lactiflora) was developed with GC-MS/MS. To determine the concentrations of pesticide residues, 5 g of dried samples were saturated with distilled water, extracted with 10 mL of 0.1% formic acid in acetonitrile/ethyl acetate (7:3, v/v), and then partitioned using magnesium sulfate and sodium chloride. The organic layer was purified with Oasis PRiME HLB plus light, followed by a cleanup with dispersive solid-phase extraction containing alumina. The sample was then injected into GC-MS/MS (2 μL) using a pulsed injection mode at 15 psi and analyzed using multiple reaction monitoring (MRM) modes. The limit of quantitation for the 296 target pesticides was within 0.002–0.05 mg/kg. Among them, 77.7–88.5% showed recoveries between 70% and 120% with relative standard deviations (RSDs) ≤20% at fortified levels of 0.01, and 0.05 mg/kg. The analytical method was successfully applied to real herbal samples obtained from commercial markets, and 10 pesticides were quantitatively determined from these samples.

Identification of host determinants of coronavirus infection informs mechanisms of pathogenesis and may provide novel therapeutic targets. Here, we demonstrate that the histone demethylase KDM6A promotes infection of diverse coronaviruses, including SARS-CoV, SARS-CoV-2, MERS-CoV and mouse hepatitis virus (MHV) in a demethylase activity-independent manner. Mechanistic studies reveal that KDM6A promotes viral entry by regulating expression of multiple coronavirus receptors, including ACE2, DPP4 and Ceacam1. Importantly, the TPR domain of KDM6A is required for recruitment of the histone methyltransferase KMT2D and histone deacetylase p300. Together this KDM6A-KMT2D-p300 complex localizes to the proximal and distal enhancers of ACE2 and regulates receptor expression. Notably, small molecule inhibition of p300 catalytic activity abrogates ACE2 and DPP4 expression and confers resistance to all major SARS-CoV-2 variants and MERS-CoV in primary human airway and intestinal epithelial cells. These data highlight the role for KDM6A-KMT2D-p300 complex activities in conferring diverse coronaviruses susceptibility and reveal a potential pan-coronavirus therapeutic target to combat current and emerging coronaviruses.

One Sentence Summary: The KDM6A/KMT2D/EP300 axis promotes expression of multiple viral receptors and represents a potential drug target for diverse coronaviruses.
Queer voice(over): Reassembling female desire in Chinese cinema
Authors: Ma Xuefei
Published: July 2023

This article discusses Chinese director Ning Ying’s 2006 film wuqiongdong (Perpetual Motion) with an emphasis on the development of queer voice(over) – a queer feminist aesthetic achievement that subverts and perverts the heteropatriarchal suppression of women’s desire. Specifically, I analyse the ways queer figure’s voice-over interacts with haptic visuality, contemporaneous image and the intertextual references between film-texts and exterior texts about the film. I argue, through queer voice(over), Perpetual Motion expands its theme beyond the issue of infidelity in a heterosexual marriage, develops a cinematic critique to the twentieth-century Chinese feminist movements and articulates female desires from multiple registers of senses, psychology and historical subjectivity. In Chinese cinema where queer voices are usually marginalized, Ning’s queer voice(over) establishes a mutually referent relation between queer and heteronormative storylines, thus circumventing the state censorship and adding queerness into Chinese-language feminist debates and cinematic expression.
Muslims and Islam in contemporary British theatre and the image of the ‘British Muslim Self’ in Guleraana Mir’s Coconut
Authors: Çakırtaş Önder
Published: July 2023

Despite their deep-seated presence in Britain, Muslims have been mostly excluded from theatre and popular entertainment. Sociopolitical restrictions have had an impact on the development of Muslim playwriting and it has taken longer than expected for Muslims to find their place within British theatre. Due to the expanding presence of Muslims in British and especially London theatres, the early twenty-first century has become a watershed for British Muslims. This article aims to show how British Muslims describe and represent their cultural, social and religious identities in theatrical works in twenty-first century Britain. Through Guleraana Mir’s play Coconut () – an example of British Muslim playwriting and representation – the representation of the relationship between Islam and Britishness will be examined. This article falls in the wider context of Islamic performances and theatre practices of the twenty-first-century Britain.
¿Qué opina el profesorado de la especialización en neuroeducación?
Authors: Bernabeu Tarí Gemma
Published: July 2023

El progreso de la ciencia en los últimos años ha supuesto un acontecimiento importante en la sociedad. Áreas científicas como la neuroeducación, otorgan nuevos conocimientos e instrumentos al profesorado para formar una educación basada en el cerebro con el fin de conocer las destrezas y habilidades de su alumnado, así como en su proceso de aprendizaje. El presente estudio tiene el propósito de descubrir y conocer el conocimiento del profesorado ante esta práctica neuroeducativa. Para este fin, se ha llevado a cabo una encuesta online dirigida al profesorado de educación infantil, primaria, secundaria, bachillerato y educación especial en la provincia de Alicante. Tras recoger y ordenar la información adquirida, se ha concretado un porcentaje donde se informa de las respuestas y grado de acuerdo sobre las preguntas del estudio realizado. Los resultados generales alcanzados ofrecen diversas contradicciones, tal vez generadas por deseabilidad social, a raíz del análisis obtenido en cuanto a la reducida formación del profesorado encuestado frente a la conforme consideración de sus conocimientos, puesta en práctica y, a su vez, necesidad de enseñanza en neuroeducación. En conjunto, los planes de estudio universitarios deben respaldar las nuevas disciplinas científicas en la formación del nuevo profesorado, las cuales se centran en el alumnado, en su rendimiento tanto académico como personal.
Comunicar los ODS para crear conciencia ciudadana: un análisis de la actividad de la Administración Pública en Twitter
Authors: Carrasco-Polaino Rafael , Piqueiras-Conlledo Paloma
Published: July 2023

La investigación analiza la comunicación en Twitter por parte de la Administración Pública en torno a los Objetivos de Desarrollo Sostenible (ODS) a través de la metodología del Análisis de Redes Sociales (ARS) y de la estadística, analizando el índice de interacción, la polaridad y la objetividad de los mensajes, descubriendo que todos los usuarios están conectados entre sí de alguna manera y que las comunidades de usuarios se establecen en torno al ámbito geográfico en donde destacan, además de las cuentas de ámbito nacional, las comunidades autónomas de Cataluña, Castilla-La Mancha, Extremadura y Aragón. En cuanto a los tuits que tratan los ODS, son escasos en volumen con respecto del total de publicaciones, siendo más objetivos que los que tratan otros temas, aunque no existen diferencias en el engagement o en la polaridad. Los políticos desde sus cuentas individuales generan mayor engagement y publican mensajes más positivos que las cuentas de ámbito nacional o regional, de la misma forma que los tuits de esta última categoría de cuentas son más objetivos. Los tuits con elementos multimedia complementarios o enlaces añadidos logran un índice de interacción más alto. Por todo lo anterior, la investigación permite que la Administración Pública pueda definir de forma eficiente su comunicación en Twitter relacionada con la Agenda 2030 a través de tuits publicados desde las cuentas individuales de los responsables de las instituciones, incluyendo elementos multimedia o enlaces a contenidos complementarios y con un sentimiento positivo y un contenido relativamente subjetivo.

Published: July 2023

Com a emergência da Covid-19, as discussões sobre vacinas passaram a ter maior repercussão em todo o mundo. Nas redes sociais, espaços em que diferentes públicos produzem conteúdos e expressam suas percepções e interesses, publicações sobre os imunizantes se tornaram um dos principais tópicos do debate público. Neste artigo, temos como objetivo identificar e analisar os sentimentos e emoções expressos em torno da vacina e dos processos de vacinação no contexto brasileiro durante os anos de 2020 e 2021. Para tanto, tomamos como recorte empírico uma amostra aleatória construída a partir de postagens públicas sobre o tema no Instagram, coletadas por meio da interface gráfica do Crowdtangle. O processo de classificação e identificação das emoções é realizado a partir dos descritores padronizados da Human-Machine Interaction Network on Emotion (HUMAINE), seguido pela adoção do modelo circumplexo (Core Affect Model) de Russell (2003). Como resultado, as análises dos dados apontam para a prevalência de emoções positivas como esperança e confiança em relação à vacina no cenário brasileiro, enquanto emoções negativas, como desaprovação e preocupação são identificadas no corpus no que se refere a fatores contextuais (a figura do então presidente Jair Bolsonaro, seus discursos e ações, assim como o avanço da Covid-19 e surgimento de novas variantes).
La Comunicación ante el reto de la transición ecológica y la economía azul: un desafío motivador [Editorial]
Authors: Fernández-Beltrán Francisco , Picó-Garcés Maria-Josep , Ouariachi Tania
Published: July 2023

El cambio climático representa la principal amenaza para la vida y el bienestar en la Tierra (Pörtner et al., 2022). Ante esta situación, es necesaria no solo la movilización de los Gobiernos, sino también de la ciudadanía y de las empresas (Krohling-Kunsch, 2015), para, conjuntamente, intentar contener este riesgo global. Es fundamental promover una conciencia ecológica más amplia en toda la sociedad. En paralelo, el Pacto Verde Europeo y el Plan de Recuperación para Europa han definido las líneas prioritarias para la economía europea, entre las que destacan las relacionadas con la transición ecológica y la economía azul, en consonancia también con los Objetivos de Desarrollo Sostenible (ODS).
En este contexto, abordamos el papel de la Comunicación ante el reto que suponen la transición ecológica y la economía azul, y cómo su intervención es crucial ante la necesidad de concienciar a la ciudadanía de las causas antropogénicas del cambio climático (Meira-Cartea, 2013). En primer lugar, para lograr una adecuada difusión de la información, a través de una actividad periodística ambiental de calidad, del uso de nuevos medios para explicar el relato ambiental y de la formación en educomunicación para combatir la desinformación (Aladro Vico, 2020). Sin información veraz, ni sin su comprensión adecuada, no se puede llegar a alcanzar el nivel de consenso mundial que necesita este debate. En segundo lugar, la Comunicación debe servir para mediar entre la ciencia y la sociedad, y para crear una conciencia ciudadana comprometida con la transición ecológica (Rodrigo-Cano et al., 2021) y la economía azul, favoreciendo así su participación activa en el diseño de nuestro planeta futuro.

El trabajo se centra en el análisis de las cartas de obligación del Archivo de Hernando Daza, mercader del siglo XVI afincado en Medina del Campo, que facilitaron las compraventas, los préstamos y los depósitos porque contenían el compromiso, otorgado ante notario, que otorgaba auténtica fe al documento público que salía de sus manos, de acreedores y deudores, compradores y vendedores, depositarios y depositantes a cumplir con lo establecido en el contrato de obligación. Pero analizamos sobre todo las notas dorsales que manos privadas escribieron en las cartas de obligación del Archivo Daza. Notas que tienen un valor informativo enorme, porque en ellas hallamos una información que no contienen las cartas de obligación, es decir, la que da cuenta del cumplimiento o incumplimiento de los pagos y los plazos contenidos en la obligación y las consecuencias de ello. En las notas encontramos un complemento informativo muy valiosos que amplía y enriquece la información contenida en las cartas de obligación.

Published: July 2023

Fourteen membered octamethyl tetraazamacrocyclic ligand salt, Me8[14]diene·2HClO4 and three isomeric ligands (LA, LB and LC) of its saturated analog have been synthesized as per literature. Interaction between the isomeric ligand LB and KX (X = SCN, NO3, Cl, Br and I) afforded white-coloured five coordinated square pyramidal potassium complexes [KLBX]. Moreover, the reaction between RbCl and LB produced five coordinated [RbLBCl] having square pyramidal geometry. Then, the axial substitution reaction on [RbLBCl] furnished a substituted rubidium complex with the same geometry of the mother complex. All the alkali metal complexes have been characterized by using modern analytical techniques. Furthermore, antibacterial and antifungal activities of ligand LB and its alkali metal (K and Rb) complexes have been investigated against different bacteria and fungi.
A Rhodamine Based Fluorometric and Colorimetric Probe for Detection of pH in Aqueous Medium
Authors: Samanta Subhodip
Published: July 2023

Present study involves a rhodamine based fluorescent probe, which is reported to exhibit high fluorescence and colorimetric response in the pH range 2.0-5.5, where 55-fold fluorescence intensity change was identified with the lowering of pH of the medium. The working principle of the probe is based on its reversible structural inter-conversion between spirocyclic ring-close (non-fluorescent) and spirocyclic ringopen (fluorescent) forms of rhodamine base along with a reversible color change between colourless and pink with change in the pH medium. The closed spirocyclic form (AX) of the probe converts gradually into the spirocyclic open-ring (HAX) with increasing acidity of the medium and which in turn results in the strong orange fluorescence emission along with visible colorimetric responses. The calculated pKa ~ 4.0 for such conversion indicates that the probe can be useful to detect the pH of the aqueous medium in the range 3.0-5.0. The probe displays high sensitivity, good photostability, and reversible pH dependence. Detailed analysis of the pH sensing capability of the probe were performed by means of UV-vis spectroscopy, steady state and time resolved fluorescence techniques and DFT/TD-DFT based theoretical calculations.
Structural, Optical, Electrical and Discharge Characteristics of PVA-ZnS Nanocomposite Polymer Electrolyte−Zn2+ Ion Conduction for Solid State Battery Applications
Authors: Venugopal R. , Sudhakar K. , Narsimlu N. , Srinivas CH.
Published: July 2023

Polyvinyl alcohol (PVA) based Zn2+ ion conducting solid polymer electrolyte was prepared using a solution-cast method. Measurements were taken utilizing X-ray diffraction (XRD) and Fourier transform infrared analysis (FT-IR) to investigate the structure. The optical absorption spectra were investigated in the 200-800 nm range in order to acquire information about the optical properties of the material. This data comprised the direct energy gap, indirect energy gap and optical absorption edge of the material. The direct optical energy gap for pure PVA lies at 6.08 eV, while PVA doped with zinc sulphide ranges from 5.28 to 5.68 eV for the different compositions. It was evident that the energy gaps and band edge values transferred to lower energies on doping with ZnS up to a dopant concentration of 92 wt.% of PVA and 8 wt.% of ZnS. For this study, the ionic conductivity and transference number of PVA polymer electrolytes were measured in order to know more about the conductivity order and charge transport in these materials. The charge transport in PVA polymer electrolyte was measured to be largely due to ions (tion = 0.97), as indicated by the transference number. Increasing the ZnS concentration and the temperature were both found to raise the ionic conductivity. The discharge properties of solid-state battery cells made with this PVA polymer electrolyte were studied while operating under a constant load of 100 kW.
Conductivity Control of Al-doped ZnO Thin Films Deposited by Radio Frequency Sputtering
Authors: Oh Dong-Cheol
Published: July 2023

Films made up of Al-doped ZnO (AZO) are the promising transparent conductive oxides. Hall measurements were used to investigate the effects of varying the sputtering parameters on the electrical resistivity, electron concentration and electron mobility of a series of AZO films produced by radio frequency (RF) sputtering. Increases in plasma power, chamber pressure, argon (Ar) flow rate and decreases in substrate temperature lead to the higher electrical resistance. However, all the samples exhibit a pattern in which electrical resistivities decrease with increasing annealing temperature (below 200-400 ºC) and increase (above 200-400 ºC). As the number of electrons increases, the electrical resistance decreases and vice-versa. The carrier compensation effect or excess carrier compensation due to the formation or annihilation of conductive defects is responsible for these shifts in the electrical characteristics. It was also found that the conductivities of the AZO films formed via RF-sputtering dependent on imperfections in structure such as ionized impurities and grain boundaries, as electron mobility is shown to be proportional to the electron concentration.

Published: July 2023

Pulmonary arteriovenous malformations (PAVMs) in children are rare lesions characterized by abnormal low resistance vascular structures connecting a pulmonary artery to a pulmonary vein, resulting in an intrapulmonary right-to-left shunt. The insidious onset and variable signs and symptoms make diagnosis difficult, especially in children. PAVMs can be single or multiple, congenital or acquired, and up to 47-80% of cases are associated with hereditary hemorrhagic telangiectasia (HHT).
Influencia de la interacción suelo-estructura estática en edificios de 100 metros de altura
Authors: Fernández Limés Aldo , Fernández Lorenzo Ingrid , Cobelo Cristiá Willian Daniel
Published: July 2023

Es práctica habitual despreciar el efecto de la interacción suelo estructura (ISE) idealizando a los apoyos de las estructuras como empotrados. Esta simplificación induce cambios en la respuesta estructural subestimando o sobrestimando los esfuerzos interiores y desplazamientos, lo que puede provocar errores en el diseño. Este trabajo analiza la influencia de la ISE en la respuesta estructural de una edificación de 100 m de altura sometida a carga dinámica de viento. La consideración de la ISE se analizó a través de métodos numéricos continuos sobre estratos de suelos compresibles homogéneos y la no consideración de su efecto a través de apoyos empotrados, con el objetivo de obtener la variación de las frecuencias de oscilación, desplazamientos horizontales y fuerzas interiores de los elementos estructurales, entre los modelos con y sin ISE. Para considerar la ISE se incorporaron elementos de interfase entre el suelo y la cimentación. Los resultados muestran que la ISE tiene un efecto considerable en el aumento de los desplazamientos laterales, en la disminución de la frecuencia de oscilación para todos los modos analizados y en la variación de las fuerzas interiores en la estructura, por tanto, su análisis es necesario cuando se proyectan edificaciones sobre suelos blandos.

Published: July 2023

La fumagina (Capnodium sp.) es una enfermedad que se presenta en los cítricos y limita el desarrollo de las plantas, al reducir la actividad fotosintética y el intercambio gaseoso. Se evaluó el efecto de cuatro tratamientos CALSU10: caldo sulfocálcico al 10%, Podas: podas de mantenimiento, CALSU10 + Podas: caldo sulfocálcico al 10% y podas de mantenimiento, Testigo: sin aplicación de caldo sulfocálcico, ni poda., en el control de la fumagina en hojas de mandarina (Citrus reticulata). Los resultados obtenidos mostraron que la incidencia de fumagina fue similar en todos los tratamientos a los 14, 28 y 42 días posteriores a la aplicación de tratamientos y a los 56 días fue mayor en el Testigo y menor para CALSU10 + Podas. Este mismo tratamiento presentó diferencias significativas (p<0,05) con respecto a los demás tratamientos a los 56 días, para la escala de daño muy severo y hojas sanas. Finalmente se concluye que, en mandarina, la severidad y la incidencia de fumagina se puede reducir en un 28 y 42% respectivamente, cuando se realizan cuatro aplicaciones de sulfocálcico al 10% junto con poda de saneamiento en el estadio fenológico de reposo vegetativo del árbol.

Baumärkte und Gartencenter in der Region München
Authors: Bleyer Burkhard
Published: July 2023

Vor einem neuen Boom der Baumärkte und Gartencenter stehen die Kommunen in der Region München. Hohe Grundstückspreise, knappes Angebot und kommunalpolitische Willensbildungen hatten ihre Weiterentwicklung lange Zeit stärker eingeschränkt.Das zugängliche Datenmaterial ist insbesondere bezüglich Umsatz und Planungsabsichten wenig ergiebig. Ausreichend verläßliche Informationsquellen mußten aufgespürt werden, um einen Sektor des Einzelhandels auf einem regional bedeutsamen Markt transparent zu machen, der von sich eher bedeckt haltenden Entscheidungsträgern beherrscht wird.Die bestehenden 34 Fachmärkte mit insgesamt rd. 115 000 m2 Verkaufsfläche sollen an neun Standorten um ca. 36 000 m2 vermehrt werden. Dieses Wachstum stellt nicht nur eine Herausforderung an den kleinteiligen Fachhandel, sondern auch an den Großhandel und an kleine Baumärkte dar. Die Dynamik in diesem Bereich zeigt sich auch in der Verringerung der Vertriebsschienen, in Konzentrationsbewegungen bei den Eigentümerverhältnissen und in der Sortimentsausweitung.Die Entwicklungsmuster dieser großflächigen Einzelhandelsformen werden auf siedlungsstrukturelle Zusammenhänge hinterfragt. Fast alle Einzelhandelsgroßprojekte durchlaufen zweistufige Planungsverfahren. Welche Ansprüche stellen Landes‑, Regional- und Bauleitplanung an diese Projekte im Rahmen von Raumordnungsverfahren und Bebauungsplänen?Es wird dargelegt, welche Hilfestllung die Landes- und Regionalplanung bei diesen Prozessen mit raumbedeutsamen Auswirkungen auf die Versorgungslandschaften und das zentralörtliche System geben (können).
Geopolitische und raumstrukturelle Veränderungen in Europa durch die Metropole Berlin aus der Sicht eines Nachbarlandes
Authors: Christiansen Ulf
Published: July 2023

Berlin wird mit seinen 5 bis 6 Mio. Einwohnern im Jahr 2010 eine europäische Metropole von großer politischer und bevölkerungsmäßiger Bedeutung sein. Die heute bestehende Arbeitsteilung unter den europäischen Großstädten wird sich jedoch in absehbarer Zeit nicht bedeutend ändern, weil die Stadt mit großen Wachstums- und Anpassungsproblemen kämpft.Die Frage des Einflusses der Maastrichter Verträger und der Umwälzungen in Osteuropa auf die Position von Berlin wird aus der Sicht eine NordREFO-Konferenz im Herbst 1992 erwähnt. Sollte es gelingen, eine funktionelle Ostseeregion zu schaffen, würde dies für Dänemark und den gesamten norddeutschen Raum bis einschließlich Hamburg und Berlin außerordentlich wichtig sein. Äußerst positiv könnte es sich hier auswirken, wenn es gelingen würde, Berlin zur tatsächlichen Hauptstadt Deutschlands zu machen; doch das wird lange dauern.Es werden Überlegungen vorgelegt, die folgende drei Bereiche angehen:
Raumordnung als indirekte Verkehrspolitik für Mittel- und Osteuropa: 24 Thesen
Authors: Heinze G. Wolfgang
Published: July 2023

Das zu erwartende Verkehrswachstum wird die Bedeutung der Raumordnung und Stadtentwicklungspolitik in Mittel- und Osteuropa nachdrücklich erhöhen. Entscheidende Wachstumskomponente ist der induzierte Neuverkehr. Da er erst über den Umweg tiefgreifender Wandlungen der Gesellschafts‑, Wirtschafts- und Verkehrsstruktur entsteht, spiegeln unsere heutigen Verkehrsprognosen vor allem Hoffnung wider. Angesichts dieses Nachfragedrucks dürften sich in den nächsten zehn Jahren im Osten wie im Westen vor allem die Strukturschwächen der traditionellen Verkehrsmittel verstärken. Die innovative Beeinflussung der Verkehrsaufteilung auf die Verkehrsträger (Modal split) wird somit zur zentralen Gestaltungsaufgabe der Verkehrspolitik. Zugleich ist nicht mehr zu übersehen, daß die entscheidenden strukturellen Lösungen des Verkehrswachstums außerhalb des Verkehrssektors liegen. „Verkehrsvermeidung“ durch Verkehrsverlagerung muß bei der Nachfragesteuerung beginnen. Deshalb entsteht gegenwärtig ein neues Leitbild umfassender alternativer Verkehrspolitik. Angesichts des tiefgreifenden Wandels unserer Siedlungs- und Produktionsstrukturen ist der Beitrag der Raumordnungs- und Stadtentwicklungspolitik zur Gestaltung des Verkehrs von morgen in den Städten von morgen besonders gefordert. In dieser Phase sind strategische Überlegungen gefragt. Da alle Programme und Pläne wesentlich mehr Zeit brauchen als erwartet, kann die Raumordnung vorziehen und Rahmenbedingungen setzen. Für den Aufbau Osteuropas und die zeitliche Abstimmung von Verkehrs- und Regionalpolitik hält die Entwicklungspolitik der 60er und 70er Jahre wesentliche Lehren parat. Zugleich verfügen die osteuropäischen Länder in dieser Neuorientierung über den großen Vorteil, auf westliche Lösungen als Module zurückgreifen zu können. Insofern entwickelt sich der Strukturwandel Ostdeutschlands bereits heute zu einem innovativen Exportartikel für Osteuropa. Die Marktchancen für eine zukunftsfähige Umgestaltung von Verkehrssystemen liegen gerade dort auf der Hand, wo sich Wirtschafts- und Lebensräume neu organisieren. Dies gilt besonders für konkrete Demostrationsobjekte erfolgreicher Verkehrsentlastung durch Raumordnung und Stadtentwicklung.
Auswirkungen der Zuwanderungen nach Bayern auf die Bevölkerungsstruktur, den Arbeits- und den Wohnungsmarkt, die Infrastruktur und den Flächenverbrauch
Authors: Koll Robert , Vogler-Ludwig Kurt
Published: July 2023

Mit der Einwanderung werden sich die Entwicklungstrends für die Bevölkerung Bayerns grundlegend ändern. Ohne Zuwanderung steht die Sozialversicherung, insbesondere die Rentenversicherung, vor einem Finanzierungsproblem, dessen Lösung in Leistungseinschränkungen, längeren Beschäftigungszeiten oder höheren Beitragssätzen zu suchen wäre.Auf dem Arbeitsmarkt wird das Angebot an Arbeitskräften (Erwerbspersonen) mit der Zuwanderung bis zum Jahre 2010 je nach Szenario um 16 bis 25 % zunehmen. Gesamtwirtschaftlich betrachtet gehen in der langen Frist von der Zuwanderung markterweiternde Effekte aus, die zu stärkerem Wachstum des Bruttoinlandsprodukts und höherer Beschäftigungsdynamik führen können. Auf die kürzere Frist ergeben sich hingegen Belastungen, die sich insbesondere in einer spürbaren Zunahme der Arbeitslosigkeit und einem Anstieg des Staatsdefizits zeigen.Geht man vom gegebenen Versorgungsgrad mit Wohnungen aus, dann stellen sich vor allem für die Regionen mit Verdichtungsräumen und insbesondere die Region München erhebliche Versorgungsprobleme.Unter den Infrastruktureinrichtungen ist der Kindergarten‑, Volksschul- und Krankenhausbereich besonders durch die Zuwanderungen betroffen. Im Kindergartenbereich ist auf bayerischer Ebene die Überlast bis zum Jahre 2010 in jedem Szenario wieder verschwunden. Im Volksschulbereich treten anders als bei den Kindergärten unter den getroffenen Annahmen auf jeder Betrachtungsebene deutliche Überlastphänomene auf; sie sind stärker bei den Hauptschulen als bei den Grundschulen, in den Regionen mit großen Verdichtungsräumen, insbesondere München, gravierender als für ganz Bayern und insbesondere das „übrige Bayern“. Der Mehrbedarf an Krankenhausbetten lehnt sich eng an die Entwicklung der Wohnbevölkerung an und steigt daher – je nach Zuwanderungsszenario – bis zum Jahr 2010 an.Bezogen auf die im Jahre 1989 vorhandene Freifläche, liegt der maximale zusätzliche Flächenverbrauch in Bayern unter 0,8 %, in den Regionen mit großen Verdichtungsräumen und in der Region München bei 2 bzw. 3,6 %. Bezogen auf die für 1989 ausgewiesene Verkehrs- und Siedlungsfläche sind die zuwanderungsbedingten Raten des Flächenverbrauchs ganz erheblich, bei sehr hohen Zuwanderungen betragen sie in der Region München rd. 25 %.

Published: July 2023

Asphalt pavements deteriorate over time when subjected to fatigue; hence, it is critical to evaluate in-service pavements to keep them in good condition. The goal of pavement evaluation is to assess the functional and structural performance of a pavement section, with a view to improving both the pavement's serviceability and riding quality. Through field and laboratory experiments, the current study attempts to evaluate the performance of pavement stretches. The sections are ranked and prioritized based on the test results. Medchal-Dabilpur national highway was evaluated for pavement roughness, skid resistance and deflections. In addition, core samples with diameters of 100mm and 150mm were collected and tested in the laboratory for moisture susceptibility, tensile strength, stiffness and fracture characteristics. The current study also intends to establish a unique technique for prioritizing pavement maintenance sections based on functional and structural performance in the field and laboratory. The Artificial Neural Network (ANN) approach was used to develop the relationship between pavement functional and structural performance. Heat maps were created and ranked in Python Jupyter notebook to better visualize the performance of functional and structural characteristics of the pavement. The final evaluation results can be validated by supporting them with laboratory investigations based on the pavement-section field samples. The results demonstrate that there is a strong relationship between the structural and functional properties of the pavement. The developed Maintenance Priority Index (MPI) will be useful in rating the maintenance and rehabilitation actions depending on the level of necessity.

Authors:   National Institute of Technology, Kumar Vishal , Aggarwal Praveen
Published: July 2023

In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits to the economy and the environment. The present study investigates the feasibility of employing Waste Cooking Oil (WCO) and Waste Engine Oil (WEO) as rejuvenators blended with reusable asphalt binder through physical and rheological properties at high and intermediate temperatures. Examined conventional properties of WCO-and WEO-modified bitumen include softening point, penetration, ductility and viscosity. In addition to these rheological properties, they also include Amplitude Sweep, Frequency Sweep, Multiple Stress Creep Recovery (MSCR), Linear Amplitude Sweep (LAS) and High-temperature Performance Grading (HTPG) tests carried out by Dynamic Shear Rheometer (DSR). The experimental outcomes revealed that both WCO and WEO could reduce deformation resistance and improve stiffness, workability and viscous behavior of aged bitumen. Moreover, the addition of waste oils improves the fatigue lives of rejuvenated bitumen and enhance fatigue cracking resistance, but at the cost of rutting resistance. Overall, WCO performs better in restoring stiff binder properties than WEO as per rheological testing. KEYWORDS: Dynamic shear rheometer (DSR), Reclaimed asphalt pavement (RAP), Rejuvenators, Waste cooking oil (WCO), Waste engine oil (WEO).

As the world shifts towards a more sustainable future, solar energy has emerged as a preeminent and economically feasible alternative to traditional energy sources, gaining widespread adoption. This study presents a reversed circular flow jet impingement (RCFJI) which aims to improve the performance of a bifacial PVT collector. An indoor experiment using a solar simulator to assess the energy, exergy, and economic efficiency of a RCFJI bifacial PVT collector. The study was carried out using a solar irradiance ranging from 500-900W/m2 and a mass flow rate between 0.01-0.14 kg/s. Energy performance-wise, the highest photovoltaic efficiency achieved was 11.38% at solar irradiance of 500 W/m2, while the highest thermal efficiency achieved was 61.4% under 900 W/m2, both obtained at 0.14 kg/s mass flow rate. Regarding exergy performance, the highest photovoltaic exergy obtained was 47.27 W under 900 W/m2 at 0.14 kg/s, while the highest thermal exergy was 9.67 W at 900 W/m2 at 0.01 kg/s. Overall, higher solar irradiance is more desirable for energy and exergy performance. Meanwhile, economic point of view, lower solar irradiance is preferable. Based on the findings, the optimal mass flow rate was 0.06 kg/s.
Kontekst w interpretacji metajęzykowych jednostek ironicznych: struktury, typy, granice (na podstawie języka polskiego, rosyjskiego i angielskiego)
Authors: Starodvorskaia Ekaterina
Published: July 2023

The paper deals with the role of context and its features in the interpretation of ironically used metalinguistic (reflexive) expressions in the Russian, Polish, and English languages. Although contextual cues have always been a major topic of interest to irony scholars, more research seems to be needed on how context interacts with a metalinguistic expression and how it indicates that such an expression is to be interpreted ironically. It is clear that the most natural context in the situation in question is speech (in a broad sense) that is referred to in particular metalinguistic expressions. Therefore, the main goal of the paper is to establish the crucial features of linguistic units that could be named and described by metalinguistic expressions and to specify relations between the former and the latter. The main criteria used to classify the examples that are analyzed in the paper are 1) the type of the linguistic unit in the context, 2) the type of contradiction between the metalinguistic expression and the context, and 3) the limits of the context that is required for ironical interpretation of the metalinguistic expression.

Background and Objectives: The purpose of this study was to develop the pandemic situational vocabulary and graphic symbols needed in AAC(Augmentative and Alternative Communication) systems for people with developmental disabilities and validate them. Methods: FGI(Focus Group Interview) was conducted with families of people with developmental disabilities, professionals working with people with developmental disabilities, speech-language pathologists, and special education teachers to explore the need for developing AAC vocabulary and graphic symbols. A vocabulary list was developed through content analysis, and graphic symbols were developed. The vocabulary and graphic symbols were evaluated for validity by 20 family members, speech-language pathologists, special educators of people with developmental disabilities, and 10 people with developmental disabilities. Results: The FGI results indicated a need to develop vocabulary and graphic symbols for infectious disease prevention, participation in telepractice activities and self-care, as well as home, time, date, weather, work life, and emotional expression. Design guidelines for graphic symbols were developed, graphic symbols were developed through a council of illustrators, and some vocabulary for movement and motion was developed as graphics interchange format (GIF) symbols. The suitability of the developed graphic symbols was validated. Conclusion: The development of AAC graphic symbols representing infection-specific prevention, telepractice activities, and social networking is expected to be very useful in the pandemic era.

Background and Objectives: This study was conducted to analyze the trends in domestic and international research on AAC for parents over the past 10 years. Method: A total of 11 studies on AAC parental education conducted between 2014 and 2023 were selected, and the overall characteristics of the research and the parental education intervention and child intervention characteristics were analyzed. Results: Research on AAC parental education has recently increased, with dependent variables including not only the improvement in children's communication abilities and parental communication-prompting strategies but also parenting stress. The most commonly used strategies in parental education were oral explanations, guidance on intervention strategies, and role-playing and rehearsal. Printed materials were also used in many parental education programs. The intervention fidelity of parents in their children's communication was assessed in almost all studies and mainly focused on topics related to daily life in a home setting. Conclusion: According to the results of this study, AAC parental education needs to first expand the verification of AAC educational effects not only for parents but also for their children, and secondly, studies using various quantitative and qualitative research methods for AAC parental education research need to be expanded. Third, it is necessary to organize the content of parental education based on the individual characteristics and needs of the child.
