Kemampuan kognitif berkaitan dengan kemampuan berpikir anak untuk mengolah, menemukan, dan memecahkan masalah dalam kemampuan logika matematika. Dalam hal tersebut, anak perlu penguasaan dari sejak dini untuk memberikan kesiapan pada tahap perkembangan berikutnya. Salah satu faktor yang menyebabkan perkembangan kognitif mengenal konsep bilangan belum mencapai tingkat perkembangan adalah kurang bervariasinya media yang digunakan oleh guru. Tujuan penelitian ini yaitu untuk meningkatkan kemampuan mengenal konsep bilangan pada anak Kelompok B di RA Masyithoh Kalisalak Limpung. Metode penelitian yang digunakan adalah Penelitian Tindakan Kelas (PTK) dengan subjek penelitian adalah anak kelompok B di RA Masyithoh Kalisalak Limpung yang berjumlah 12 anak. Teknik pengumpulan data menggunakan observasi, tes, dan dokumentasi. Teknik analisis data menggunakan rumus rata-rata nilai, presentase ketuntasan belajar dan data observasi. Hasil dari penelitian ini membuktikan bahwa pembelajaran menggunakan metode tutup botol bekas dapat meningkatkan hasil belajar maningkatkan kemampuan mengenal konsep bilangan. Hal tersebut terlihat dari peningkatan rata-rata siswa dan perubahan keaktifan dalam mengikuti pembelajaran yang juga mengalami peningkatan. Di siklus pertama terjadi peningkatan 25% dalam kegiatan menggunting dan melipat kertas dilanjutkan di siklus kedua yang mendapatkan hasil signifikan meningkat 60%. Siklus ketiga dilakukan untuk mendapatkan hasil yang lebih maksimal sehingga mendapatkan peningkatan 80%.

Postcensura en streaming: Alienación política de millenials y centennials hacia las producciones audiovisuales
Authors: Fernández-Rodríguez Carlos , Romero-Rodríguez Luis M. , Castillo-Abdul Bárbara 
Published: August 2024

Esta investigación examina el grado de alienación política que los espectadores consideran tener respecto a las producciones audiovisuales. Para ello, se aplicó una encuesta a 998 millennials y centennials en España y México, los dos países hispanohablantes que más OTT[1] consumen. Los resultados muestran que los jóvenes consideran legítimo quejarse en redes sociales a una productora audiovisual cuando una serie o película refleja una visión que no les gusta, lo que posiblemente fomenta un escenario de "dictadura de la audiencia" sobre los creadores de contenidos audiovisuales, que afecta a la libertad creativa y a la libertad de expresión. En este sentido, parece que los jóvenes que tienen el poder discursivo en las redes sociales para cambiar y censurar producciones ven plausible utilizar este canal como denuncia o queja.

[1] The acronym OTT stands for "Over The Top". In the world of technology and communication, this term is used to refer to "free transmission", i.e., content that does not require an operator for its distribution. The way in which this content is distributed is through the Internet via applications (AIMC, 2021).

Objective: To determine the frequency of clinico-hematological features and JAK 2 status of young adults presenting with Polycythemia Vera at the department of hematology. Study Design: Cross-sectional study. Setting: Department of Hematology, RMI Hospital, Peshawar. Period: 25th November 2023 to 25th May 2024. Methods: A total of 190 patients aging between 18-45 years and presented as suffering from Polycythemia Vera as per diagnosis of consultant hematopathologists, were included in this study. Samples with clear evidence of hemolysis, coagulation, or clots were excluded. Patient’s demographics, details of physical appearance, clinical findings and history of adverse events were recorded. Hematological and pathological investigations were done and analysis of JAK2 V617F mutation was conducted using polymerase chain reaction from the diagnostic lab of the institute. The primary outcome of the study was to determine the frequency of clinico-hematological features and JAK 2 status. Results: The Mean±SD of age in our study was 36.81±6.11 years with an age range of 21-45 years. Out of total patients, 49 (25.79%) patients were asymptomatic. The major symptoms affecting the daily life activities were headache 65 (34.21), abdominal discomfort 41 (21.58%), blurred vision 27 (14.21%) and fatigue 27 (14.21%). These patients had plethoric face 61 (32.11%), splenomegaly 64 (33.68%) and budd-chiari syndrome 8 (4.21%). The results of hematopathological findings showed abnormal hemoglobin (17±3.92 gm/dL), hematocrit (52.94±4.8 g %), platelet (579.63±227.68 103/μL) and leukocyte (10.32±2.6, 103/μL) levels while 177 (93.16 %) patients had mutated JAK2 levels. Conclusion: Plethoric face and splenomegaly are the commonly found clinical findings in patients with Polycythemia Vera while these patients also have abnormal levels of hemoglobin, hematocrit, platelet and leukocyte. JAK 2 status serves conclusive role in the diagnosis of Polycythemia Vera.
