Penerapan Model Pembelajaran Problem Based Learning pada Pembelajaran Matematika Materi Lingkaran di Kelas 6
Authors: Masridah Masridah 
Published: December 2024

Tujuan penelitian ini untuk menerapkan model pembelajaran Problem Based Learning (PBL) pada pembelajaran matematika. Pembelajaran matematika dianggap sangat menyulitkan, tingkat pemahaman siswa akan konsep lingkaran sangat rendah, ditambah lagi dengan ketidak aktifan siswa dalam belajar, juga sulitnya memecahkan masalah. Seorang pendidik dituntut mampu menerapkan model pembelajaran yang tepat. Dalam model PBL, bukan hanya hafalan tentang fakta, tetapi mengajak siswa untuk memecahkan masalah dalam dunia nyata (Heni Nafiqoh, 2021). Metode penelitian yang digunakan metode kualitatif. Dalam PBL terdapat lima fase, yaitu fase kesatu orientasi pada masalah, fase kedua mengorganisasikan siswa, fase ketiga membimbing penyelidikan idividual maupun kelompok, fase keempat mengembangkan dan menyajikan hasil karya dan fase kelima menganalisis dan mengevaluasi proses pemecahan masalah. Dampak positif dari penerapan PBL, yakni semua siswa tampak aktif, berpikir kritis, juga dapat berinteraksi sosial dalam kelompoknya. Dalam penerapannya PBL memiliki beberapa hambatan, sehingga guru harus mempersiapkan diri sebaik mungkin, mulai dari sarana prasarana juga siswanya.
“How Can We Help You?” Older Adults’ and Care Partners’ Perspectives on Improving Care in Hospital: A Mixed Methods Study
Authors: Lupo Mercedes , Wong Eric , Reppas-Rindlisbacher Christina , Lee Justin , Gabor Christopher , Patterson Christopher 
Published: December 2024

Background
Hospitalized older adults have unique physical, emotional, and psychosocial needs. We sought to understand older patients’ and care partners’ experiences with multicomponent interventions that support age-friendly care and identify areas for improvement.
Methods
We conducted a mixed methods study using surveys and interviews to explore older adult patients’ (65 years or older) and their care partners’ experiences with hospital-delivered multicomponent initiatives. We recruited participants from the Geriatric Rehabilitation (GRU) and Musculoskeletal (MSK) Rehabilitation units in a Canadian academic hospital from October 2021 to April 2022 until we reached data saturation and no new themes emerged.
Results
We recruited 18 participants, 10 patients (mean age 78 years, 80.0% female) and 8 care partners (mean age 61, 87.5% female). Surveys revealed overall positive experiences with multicomponent interventions. Interviews revealed five themes: 1) various forms of companionship for patients, 2) recreation and entertainment, 3) physical activity, 4) communication, and 5) pleasant physical environment. Having forms of companionship and proper communication with the care team were highlighted as areas of importance. Physical activity was highly valued, but participants expressed hesitation around safety of mobilizing without physiotherapists. Recreational activities helped distract from social isolation during a hospital stay and participants had diverse preferences for activities. Participants had strong memories of the physical environment, including the lack of natural light, institutional-like décor, and smells.
Conclusion
Companionship, recreation and entertainment, physical activity, communication, and the physical environment were important to hospitalized patients and their care partners. Hospital administrators and policy makers should consider these when targeting areas to improve care for the aging population.
New Disability in a Cohort Study of Older Men—The Manitoba Follow-Up Study
Authors: St John Philip D. , Nowicki Scott , Tate Robert B. 
Published: December 2024

Background
There is a large literature on the prevalence of disability in older men, but less data on the incidence of new disability.
Objectives
1. To determine the incidence of moderate-to-severe dis-ability in a prospective cohort study of aging men; and 2. To determine predisposing risk factors for new moderate to severe disability.
Design & Setting
The Manitoba Follow-up Study is a closed cohort study. In 1948, the initial sample was 3,983 men who qualified for air crew training in the Royal Canadian Air Force. In 2004, there were 796 men who were still alive and responded to the annual questionnaire with no missing data, and who did not have disability. The mean age at that time was 84.
Methods
We calculated the incidence of new moderate-to-severe dis-ability from 2004 to 2017, calculated the time to disability, and constructed survival analysis models to determine factors which predicted disability.
Results
The incidence of disability increased with the aging of the cohort and ranged from 4% to 12% per year. In unadjusted models, poor self-rated health (SRH), low life satisfaction, a low score on the Physical Component Score (PCS) of the Short Form–36, and the number of chronic conditions were all associated with new disability. In adjusted models, SRH, the PCS, and the number of chronic conditions were associ-ated with new disability.
Conclusions
Global measures of well-being, as well as multimorbidity, predict new disability.
Dokumentarische Forschung in der Sportpädagogik. Ein Scoping Review zu methodischen Varianten und gegenstandsbezogenen Fokussierungen

Published: December 2024

Die Dokumentarische Methode erfährt besonders in der vergangenen Dekade eine erhöhte Aufmerksamkeit in der deutschsprachigen Sportpädagogik. Das zeigt sich v. a. in einer Vielzahl neu erschienener empirischer Studien, die in ihrer methodischen und gegenstandsbezogenen Ausrichtung kaum noch zu überblicken sind. Es fehlt bislang an Untersuchungen, die sich systematisch diesen Studien mit ihren übergeordneten Erträgen und Desiderata widmen. Auf Basis eines Scoping Reviews (N=37) untersucht der Beitrag für den Untersuchungszeitraum von 2000-2023 folglich die Frage, welche methodischen Varianten und gegenstandsbezogenen Fokussierungen dokumentarischer Studien sich in der sportpädagogischen Forschung abzeichnen. Er gibt einen Überblick entlang quantifizierbarer Merkmale und vertieft diesen Überblick durch eine Einordnung der Studien in die Forschungsfelder des schulischen und außerschulischen Sports. Dadurch werden Grundlagen für ein vertieftes Verständnis dokumentarischer Forschung in der Sportpädagogik geschaffen sowie Optionen zur Selbstvergewisserung geliefert. Letztere können dazu beitragen, Anschlussmöglichkeiten für zukünftige empirische Studien und method(olog)ische Reflexionen auszuloten.

Published: December 2024

Transport, w szczególności transport drogowy, jest obok energetyki i przemysłu jednym z największych emitentów gazów cieplarnianych i zanieczyszczeń negatywnie wpływających na klimat, zdrowie ludzi i środowisko naturalne. Mimo szeregu kontrowersji wydaje się jednak, że kluczowym środkiem do ograniczenia kosztów zewnętrznych transportu jest jego elektryfikacja. Pojazdy elektryczne ze względu na ograniczony zasięg i długi czas potrzebny na ładowanie wymagają rozbudowanej sieci punktów ładowania. Niska dostępność do tej sieci hamuje rozwój elektromobilności. Polska ma szczególnie dużo do zrobienia w tej kwestii. Dlatego też celem niniejszego artykułu jest opracowanie autorskiego algorytmu oceny lokalizacji stacji ładowania maksymalizującej ich użyteczność dla osób eksploatujących samochody elektryczne. Opierając się na uprzednich badaniach ankietowych wśród obecnych i potencjalnych użytkowników oraz studiach literatury przedmiotu stworzono narzędzie do oceny potencjalnych i istniejących lokalizacji stacji ładowania. Jego główną zaletą jest jego kompleksowość i równocześni łatwość w użyciu. Dlatego powinien powszechnie służyć samorządom lokalnym do oceny planowanych na ich obszarze stacji ładowania.

Published: December 2024

Introducción: La enfermedad coronaria aguda es la principal causa de muerte en todo el mundo, sin embargo el infarto de miocardio en pacientes jóvenes (menores de 40 años) y en ausencia de aterosclerosis de las arterias coronarias es un fenómeno muy poco frecuente, que además de los factores de riesgo tradicionales se asocia a una variedad de factores contribuyentes entre ellos el abuso de drogas tales como la cocaína o marihuana, mutación del factor V de Leiden, anticonceptivos orales en mujeres jóvenes, deficiencia de proteína C y S, consumo excesivo de bebidas energéticas. La proteína C (PC) es un componente importante de la coagulación, dependiente de vitamina K y que requiere trombina en la superficie de células endoteliales para formar la PC activada, que ejerce su efecto anticoagulante inhibiendo a los factores Va y VIIa . Una deficiencia de la PC plasmática dará como resultado un estado protrombótico. La deficiencia de PC ocurre en el 0.02-0.05% de la población general, se halla en el 2-5% de los eventos tromboembólicos incidentes y hasta el 10 % de los recurrentes. En 1993 se describió por primera vez la deficiencia de PC y su principal presentación clínica es el tromboembolismo venoso, sin embargo, poco a poco se describen con mayor frecuencia eventos tromboembólicos arteriales agudos vinculados a esta enfermedad.
Caso clínico: Hombre de 26 años, ingresa a emergencia con angina de pecho luego de ingesta de bebida energizante y realizar ejercicio de natación. El electrocardiograma demostró isquemia con ondas ondas T hiperagudas de V2-V4 y posteriormente supradesnivel del ST en V2-V6 con extrasístoles ventriculares. La ecografía cardíaca demostró hipocinesia del TIV medioapical y pared anterior medioapical, con Fevi 50%. La troponina I > 40, Troponina T=5814. El manejo se realizó con analgésicos, nitroglicerina e intervencionismo. En hemodinamia se evidencia lesión crítica 95% a nivel de arteria DA proximal con presencia de trombo de gran diámetro luminal, se realiza angioplastia con stent farmacoactivo. El panel de drogas en orina fue negativo, Panel reumatológico de 9 anticuerpos negativos, C3 y C4 normales. Proteina C: 62.5 (Bajo), Proteina S, Cardiolipina IgM, Cardiolipina IgG y Dímero D normales. En hospitalización desarrolla insuficiencia renal aguda AKIN II y neumonía atípica tratándose de manera satisfactoria. Se maneja con enoxaparina 60 bid, clopidogrel 75 mg, ASA 100, colchicina 0.5 mg y amiodarona 200 mg.
Conclusión: La deficiencia de proteína C es una patología muy rara como causante de infarto de miocardio. Al ser una patología trombótica es imprescindible el seguimiento conjunto con Hematología.
A Comprehensive Review: Recent Advances in the Management of Retinopathy of Prematurity (ROP)
Authors: Sai Ganesh M. 
Published: December 2024

Retinopathy of prematurity (ROP) is a unique, proliferative vasculopathy in the retina of premature infants has set off the major cause of blindness in preterm infants throughout the world. In 1940s and 1950s it is also known as Retrolental Fibrioplasia. Propranolol, a non selective beta adrenergic receptor inhibitor is used for ROP in various studies. Propranolol is used in infantile hemangioma due to blocking of VEGF (Vascular Endothelial Growth Factor) i.e it is tested for the RNV (Retinal Neo-Vascularization). Caffeine plays key role in the prevention of ROP progression. It is a frequently used drug in prematurity for the reduction of retinopathy in preterm infants. Adding supplementation of poly unsaturated fatty acids to the mother may mitigate the risk of ROP in premature infants. Vitamin A shows action by acting blocking of VEGF production. By providing vitamin A as a supplement during pregnancy it shows the reduction in ROP in premature infants. Exposure to the light may influence the ROP. Some studies had proven that light exposure may affect the progression of ROP. A red light exposure shows reduction in progression of ROP at 670 nm shows good results of development in ROP infants. NSAIDS such as ibuprofen and indomethacin are the widely used drugs in the treatment of ROP. Some studies have showed the effect of Insulin like growth factor - I (IGF-I) supplementation will give the potent outcomes in the management of ROP. A potential therapeutics strategy to treat ROP is with gene therapy using viral vectors. The most commonly used vector for humans can be adeno-associated virus because of its low immunogenicity. The first FDA approved adeno-associated virus gene therapy is the Voretigene neparvovec to treat inherited retinal dystrophy caused by mutation of the RPE65 gene. It is very much essential to identify the novel therapeutics for ROP as the available therapies are causing unfavourable ocular outcome and also showing long term systemic effects on other organs. Gene therapy, cell therapy and non-coding RNAs have been shown a great impact in the management of ROP and further investigations are required to investigate the emerging treatment strategies.
