Kaikki keinot käyttöön – Helpottaisiko suualueen motoriikan passiivinen harjoittelu korjaamaan sitkeitä äännevirheitä?
Authors: Virkki Johanna , Rantala Leena
Published: June 2021

Vaikka kuntoutusmenetelmien pitäisi pohjautua näyttöön perustuvaan toimintaan, kuntouttajan työkalupakkiin eksyy välillä keinoja, jotka on napattu muun toiminnan alueelta. Yksi tällainen harjoitteluväline on suun alueen lihaksia vahvistava, alun perin kuorsaukseen ja uniapnean hoitoon kehitetty laite, FaceFormer (FF). Puheterapeutit käyttävät laitetta erityisesti niiden lasten kanssa, joilla äänteiden oppiminen on huomattavan hidasta ja työlästä. Tässä artikkelissa esittelemme kokeilun, jossa arvioitiin, edistyikö kielen liikkeen hallinta 7-vuotiaalla huuli- ja suulakihalkiolapsella, kun hän käytti FF:ia 12 viikon ajan öisin. Harjoittelujakson tavoitteena oli, että lapsi nostaa kielensä hammasvallille (esim. /r/:n, /s/:n ja /l/:n ääntymäpaikka) ja pitää sitä siinä mahdollisimman pitkään ilman leuan myötäliikkeitä. Kielen nostoa arviointiin viikoittain, ja lapsi vastasi samalla kyselyyn siitä, miltä kojeen käyttö ja kielen liike tuntuivat. Lisäksi lasta hoitava puheterapeutti arvioi leuan ja kielen liikkeiden eriytymisen kehittymistä. Kokeilussa tehtyjen havaintojen mukaan lapsen kielen motoriikka parani: kielenkärki pysyi hammasvallilla pitempään kuin ennen FF:n käyttöä. Varsinkin yhdeksännen viikon kohdalla motoriikassa tapahtui selvä harppaus: kielenkärki pysyi tavoitepaikassa kaksinkertaisen ajan verrattuna aiempiin mittauksiin. Kielenkärjen nosto hammasvallille alkoi onnistua myös puheen aikana arviointitilanteessa ilman, että lapselle annettiin hänen aiemmin tarvitsemaansa visuaalista tai taktiilista tukea. Lapsen oma kokemus laitteen käytöstä oli pääasiassa myönteinen, ja myös kielen kärjen nosto tuntui hänestä helpolta.

Simvastatin Toxicity Induces Mitochondrial Dysfunction in Rat Skeletal Muscle
Authors: Zulfahmidah  , Hardjo Marhaen , Kadir Syahrijuita
Published: June 2021

Background: Statins are the class of drugs that are widely used for lowering LDL cholesterol and as primaryand secondary prevention to cardiovascular disease. However, the widespread use of statins is constrained bythe presence of toxicity or intolerance, which affects drug control rates. The toxicity or intolerance of statinsranges from 10-15%. The most common statin toxicity is statin-associated muscle symptoms (SAMS). Theunderlying mechanisms of SAMS involve the disruption of mitochondrial biogenesis, potential membranechanges, reduced number of mitochondria, and changes in protein oxidative activity due to the accumulationof ROS in cells and tissues. The disruption of mitochondrial biogenesis can be marked by a decrease ofperoxisome proliferator-activated receptor co-activator gamma (PGC-1a). This study aimed to determine theeffect of simvastatin on skeletal muscle PGC-1a.Methods: Sixteen female Wistar rats (8-10 weeks of age) were randomized into 2 groups: (1) control group(n=8), and (2) simvastatin group(n=8). For 30 days, the simvastatin group was exposed to simvastatinat a dose of 10 mg/kg/day. Meanwhile, the control group animals only received 0.5% methyl cellulose.Gastrocnemius muscles were collected and PGC-1a levels were evaluated by using ELISA Kit.Results: Following 30 days of treatment, a significantly lower level of skeletal muscle PGC-1awas observedin the simvastatin group compared to the control group (p = .026).Conclusion: Our finding indicates that administration of simvastatin at a dose of 10 mg/kg/day for 30 daysmay decrease skeletal muscle PGC-1a leading to mitochondrial dysfunction in rat skeletal muscle.

Näherungsgleichungen zur Vorhersage von Temperaturübertragungsgraden an Wärmeübertragern – insbesondere zur Wärmerückgewinnung
Authors: Huber Heinrich , Kaup Christoph
Published: June 2021

Als wesentliche Leistungskenngröße einer Wärmerückgewinnung (WRG) dient der Temperaturänderungsgrad sowohl bei privatrechtlichen Vereinbarungen wie auch bei gesetzlichen Anforderungen. Üblicherweise werden zur Festlegung ein Wärmekapazitätsstromverhältnis von 1 und ein definierter Referenzmassenstrom vorausgesetzt. In der Praxis müssen aber Leistungsnachweise oft bei abweichenden Betriebszuständen durchgeführt werden. Dabei besteht der Bedarf nach einfachen Näherungsgleichungen zur Umrechnung auf die Referenzbedingungen. Zudem sind für die Beurteilung der Messunsicherheit bei Labor- und Feldmessungen Modelle gefragt, die neben dem Einfluss der Temperaturen auch die Massenströme berücksichtigen.
Legionellen in kaltgehenden Trinkwasser-Installationen: Hygienerisiko oder Hype?

Published: June 2021

Als 2011 in die Trinkwasserverordnung der technische Maßnahmenwert für Legionellen aufgenommen wurde, konzentrierte sich die Fachwelt aus gutem Grund auf die Hygienerisiken in Trinkwasser warm-Zirkulationen. Aktuell werden aber zunehmend Legionellenbefunde in kaltgehenden Trinkwasser-Installationen thematisiert. Dass hiervon eine Gesundheitsgefahr für die Nutzer ausgeht, ist allerdings kein neuer Verdacht: Verschiedene Studien und Untersuchungen haben inzwischen das Verständnis für die Problematik erweitert. Daraus lassen sich konkrete Handlungsempfehlungen für Planer und Fachhandwerker ableiten.

Published: June 2021

Die Temperierung von Gebäuden durch Heizung oder Kühlung erfolgt oft mit einem wassergefüllten Rohrleitungssystem. Das Wasser als Energieträger wird von entsprechenden Erzeugeranlagen wie zum Beispiel Heizungskessel, BHKW oder Fernwärmeanlagen mit einer bestimmten Temperatur zu den Verbrauchern gebracht. So wie die Wärmebrücken in der Gebäudehülle an Beachtung gewonnen haben, wird auch verstärkt Augenmerk auf die optimale Hydraulik gelegt, um eine effiziente Anlagentechnik zu garantieren.

Published: June 2021

The recent worldwide pandemic, COVID-19, pushed students of all ages to remote learning in a matter of days. This abrupt change in the mode of delivery of instruction affected students differently. The researchers share findings of a study conducted among university preservice education students from Texas and Ohio concerning students' preparedness for this drastic change. The study sought to identify and document recurring themes about the students' experiences of remote learning and to determine how significantly socioeconomic status (SES), sociocultural values (SCV), and socioemotional learning (SEL) aspects impacted students’ transition to remote learning at these universities. Implications for university instructors and ways to improve educational experiences during such unprecedented times are discussed.
College Enrollment and STEM Major Choice in a Rural State

Rural students account for almost 20% of the US K-12 students, but rural context varies from state to state. This study uses a statewide longitudinal sample (N = 3,119) to analyze college enrollment and STEM major choice patterns of Montana’s public high school students in the academic years of 2013-2017. The binary logistic regressions showed that Montanan students are more likely to enroll into a 4-year institution than a 2-year institution. Also, students enrolled at a 4-year institution are more likely to consider STEM majors than students at a 2-year institution. Although high school GPA and ACT STEM scores are strong predictors for both college enrollment and STEM major choice, findings for race/ethnicity, gender, and free or reduced-price lunch status varied across the two outcomes. Specifically, race/ethnicity contributes to variation in college enrollment, but not STEM major choice. Similarly, free or reduced-price lunch status in high school is predictive of college enrollment, but not for STEM major choice. Although there was no difference in college enrollment type for gender, male students are more likely to select a STEM major, and this trend occurs at a rate of three times higher at a 4-year institution versus a 2-year institution. Our findings provide additional nuances of rural students, contributing to the understanding of their college enrollment and STEM major choices in the context of Montana - a large geographic, low populous state - which has received less attention than urban and high-density states.

Problem representation in speciﬁc domains has raised great attention in the past years. In mainland China, research of the primitive physics problem teaching has been booming in the physics education domain recently. This study proposes six representations in the process of solving problems for middle school students, including abstraction representation, assignment representation, image representation, physics representation, methodology representation and mathematics representation. The measuring instrument of primitive physics problem for junior high school students was developed according to previous research and the principle of “Objectively Evaluating Subjective Questions”. The participants were 113 grade nine students in mainland China. The results of conﬁrmatory factor analysis confirm the eﬀectiveness of the measuring instrument. A weak correlation between the measuring instrument of primitive physics problems and Lawson Classroom Test of Scientiﬁc Reasoning (LCTSR) was found. Therefore, we believe that the primitive physics problem solving ability is a unique ability which is different from the general reasoning ability. This study demonstrates that using the measuring instrument of primitive physics problem to measure junior high school students’ ability of problem solving is promising.
Economía circular, un modelo de transformación
Authors: Montaño Arévalo Anyi Carolina
Published: June 2021

En el presente artículo se hace una revisión temática a la economía circular como enfoque de gestión y de desarrollo en el marco de la crisis ambiental relacionada con los modelos de producción industrial. A partir de la necesidad de realizar una adecuada gestión de residuos en los procesos industriales, los teóricos de la economía circular han puesto de relieve la importancia de pensar en la vida útil de los productos y en el impacto de estos en el ambiente. Según cifras de la Plataforma Intergubernamental sobre Biodiversidad y Servicios de los Ecosistemas (IPBES) en América el daño abarca el 31% y cada año se estima que desaparecen de 2 a 4 especies de vertebrados, resultado de la adopción de un sistema económico lineal donde las materias primas son usadas y luego desechadas de forma excesiva, sin considerar la afectación al medio ambiente. El artículo busca aproximarse a los diferentes aspectos de la economía circular y su incidencia en las decisiones empresariales y de desarrollo a nivel regional, así como el impacto que tienen estos modelos en la preservación de los recursos y ecosistemas y las metas de desarrollo sostenible.

La educación a la primera infancia, es un ciclo vital en el desarrollo del ser humano, enmarcado jurídicamente y reconocido por primera vez de manera legal en el Código de la Infancia y Adolescencia (Artículo 29, Ley 1098 de 2006): "la primera infancia es la etapa del ciclo vital en la que se establecen las bases para el desarrollo cognitivo, emocional y social del ser humano”.  Partiendo de lo anterior, se ha ampliado la cobertura para esta población sin medir el tipo de infraestructura que les garantice a los niños y niñas el bienestar y fortalecimiento de sus necesidades básicas. Donde se han venido adecuando casas de tipo doméstico, en zonas residenciales, con poco o nada de espacio de zona verde, lo que no le permite al niño vitalizar su motricidad gruesa con total plenitud. Este artículo reconoce los beneficios que tiene para la primera infancia, el fortalecimiento de la motricidad gruesa y hace un aporte para crear la necesidad a este tipo de instituciones educativas a aplicar actividades que contribuyan al fortalecimiento motriz, pese a no contar con espacios los adecuados para su desarrollo.
