     Students are at high risk of emergencies as various incidents can occur within this group. Additionally, children spend significant time at school, increasing their risk of injury. Emergencies can happen unexpectedly and anywhere, including at home, on the road, and within the school environment. Most injuries in children are directly related to physical activities outside, with many injuries occurring during school hours. This study was quasi-experimental, focusing on one group without randomization. The design employed a pre-and post-test approach using the Wilcoxon test. The study was conducted in May 2023 with 38 respondents. Results: Based on the results, the "good" category, which initially had 0% of respondents, became 100%, while the "poor" category, which initially had 89.5% of respondents, became 0%. The knowledge score of teachers improved from 0.001 before receiving the JATUR Booklet to 0.002 after receiving it. Thus, it can be concluded that there is a difference before and after the intervention of providing the booklet, with a non-normal distribution (p0.05). There is an increase in knowledge scores after providing the Falling and Injured (JATUR) First Aid Booklet.  ABSTRAK   Latar Belakang : Siswa sekolah merupakan kelompok yang beresiko tinggi terhadap kejadian gawat darurat karena banyak kemungkinan yang dapat terjadi pada kelompok tersebut. Selain itu anak-anak menghabiskan banyak waktu di sekolah, yang membuat anak-anak memiliki resiko yang lebih besar terjadinya cedera. Kegawatdaruratan dapat terjadi secara tidak terduga dan bisa terjadi di mana saja seperti dirumah, dijalan dan di lingkungan sekolah. Mayoritas cedera dan luka pada anak secara langsung berhubungan dengan aktivitas fisik diluar, cedera terjadi di jam sekolah. Metode Penelitian : Jenis penelitian ini adalah quasi experiment, penelitian eksperimen dilakukan terhadap satu kelompok dan tidak dilakukan dengan cara pengacakan. Rancangan penelitian menggunakan pre and posttest menggunakan uji wilcoxson. Dilakukan pada bulan Mei 2023 dengan 38 responden. Hasil Penelitian : Berdasarkan hasil penelitian kategori baik yang awalnya 0 (0%) responden, menjadi 38 (100%) responden dan kategori kurang yang awalnya 34 (89.5%) responden, menjadi 0 (100%) responden. Di peroleh hasil pengetahuan guru sebelum di berikan Booklet JATUR 0,001 dan sesudah diberikan 0,002. Berdasarkan keterangan di atas maka di dapatkan kesimpulan bahwa ada perbedaan sebelum dan sesudah diberikan intervensi pemberian Booklet, distribusi tidak normal (p-0,05). Kesimpulan : Terdapat peningkatan skor pengetahuan sesudah diberikan media Booklet pertolongan pertama jatuh terluka (JATUR). Kata kunci : Booklet, penanganan jatuh pada anak, SD, pengetahuan pertolongan pertama &nbsp

    We use Perron method to construct a weak solution to a two-phase free boundary problem with right-hand-side. We thus extend the results of the pioneer work of Caffarelli for the homogeneous case

    Capital structure of portuguese hotel firms: a structural equation modelling approach

    This paper addresses capital structure determinants for Portuguese hotel firms between 2006 and 2014. Secondary data from 356 hotel units was analysed using the partial least squares (PLS) statistical technique, a variance-based structural equation modelling (SEM). The results show that the explanatory variables proposed as capital structure determinants have an impact on the financing and debt decisions made by the firms in the sample. Of these, tangibility has the greater explanatory power. Overall, the results support the notion that trade-off theory and pecking-order theory are important in explaining the capital structure of the Portuguese hotel industry, particularly as regards the agency conflicts triggered by growth opportunities and the preference firms have for internal funding. The results also point to the importance of collateral in accessing credit and the lesser impact of asymmetric information pertaining to tangible asset value and firm size. The results suggest small firms find it difficult to contract loans, which can somewhat limit their growth and performance.info:eu-repo/semantics/publishedVersio

    Solution Map Analysis of a Multiscale Drift-Diffusion Model for Organic Solar Cells

    Full text link
    In this article we address the theoretical study of a multiscale drift-diffusion (DD) model for the description of photoconversion mechanisms in organic solar cells. The multiscale nature of the formulation is based on the co-presence of light absorption, conversion and diffusion phenomena that occur in the three-dimensional material bulk, of charge photoconversion phenomena that occur at the two-dimensional material interface separating acceptor and donor material phases, and of charge separation and subsequent charge transport in each three-dimensional material phase to device terminals that are driven by drift and diffusion electrical forces. The model accounts for the nonlinear interaction among four species: excitons, polarons, electrons and holes, and allows to quantitatively predict the electrical current collected at the device contacts of the cell. Existence and uniqueness of weak solutions of the DD system, as well as nonnegativity of all species concentrations, are proved in the stationary regime via a solution map that is a variant of the Gummel iteration commonly used in the treatment of the DD model for inorganic semiconductors. The results are established upon assuming suitable restrictions on the data and some regularity property on the mixed boundary value problem for the Poisson equation. The theoretical conclusions are numerically validated on the simulation of three-dimensional problems characterized by realistic values of the physical parameters

    PERAN PEMBELAJARAN IPA BERBASIS HIGHER ORDER THINKING SKILLS (HOTS) DI SD KELAS TINGGI ERA SOCIETY 5.0

    Get PDF
    Dalam melakukan pemerataan, program pemerintah mencanangkan era society 5.0. Era society 5.0 ini dicetuskan oleh pemerintah Jepang dengan konsep masyarakat yang berpusat pada manusia (human centered) dan berbasis teknologi (technology based). Diluncurkannya era society 5.0 ini menjadi peluang dan tantangan untuk masyarakat khususnya siswa dalam meningkatkan keterampilan belajar sebagai modal untuk masa mendatang. Perlunya siswa menghadapi tantangan era society 5.0 ini, maka siswa harus menerapkan pembelajaran IPA berbasis HOTS (higher order thinking skills), yang merupakan proses berfikir siswa dengan level kognitif yang lebih tinggi yang dikembangkan dari berbagai konsep taksonomi pembelajaran seperti taksonomi Bloom, taksonomi pembelajaran, pengajaran dan penilaian. Tujuan dari siswa menerapkan HOTS, yaitu agar meningkatkan kemampuan siswa dalam berfikir kritis pada level yang lebih tinggi. Jenis penelitian ini yaitu penelitian kualitatif dengan metode studi literatur. Hasilnya dengan menerapkan pembelajaran berbasis HOTS di SD kelas tinggi melatih kemampuan siswa untuk berpikir kritis, kreatif, memecahkan masalah sendiri dengan pengetahuan yang dimiliki
