Aplicación interactiva para el aprendizaje con evaluaciones en el área de las matemáticas

The following document presents the development process of an interactive mobile application, as a support strategy for the teaching - learning process in the area of mathematics, for students of the Educational Experience (EE), Fundamentals of Mathematics at the Faculty of Statistics and Informatics. Using User Centered Design (UCD), which proposes to put the client at the center of research and design, to obtain an application that achieves a user experience (UX), satisfactory, when interacting with the application, allowing greater speed in the completion of tasks, which is simple to learn and intuitive, this to increase its pleasure and ease of use for the beneficiary, obtaining these results with usability tests to the application. All this because currently many applications are known as support in the area of mathematics, which have usability problems obtaining a bad UX. This work follows a user-centered methodology to create usable applications and a good UX for university students in the area of mathematics.

Outcomes in Pediatric Post-Cardiotomy ECMO Support With Modification of Systematic Support Strategy

Background Utilization of extracorporeal membrane oxygenation (ECMO) support in the post-cardiotomy setting is vital to successful perioperative outcomes following pediatric cardiac surgery. Specific analysis of protocolized management strategies and staff preparedness is imperative to optimizing institutional ECMO outcomes. Methods All patients requiring post-cardiotomy ECMO support at a single institution from 2013 to 2019 were retrospectively reviewed. In 2015, several modifications were made to the ECMO support paradigm that addressed deficiencies in equipment, critical care protocols, and staff preparedness. Cases were stratified according to era of ECMO support; patients supported prior to paradigm change from 2013 to 2015 (Group EARLY, n = 20), and patients supported following the implementation of systematic modifications from 2016 to 2019 (Group LATE, n = 26). The primary outcomes of interest were survival to decannulation and hospital discharge. Results Median age at cannulation was 24.5 days (IQR 7-96) and median duration of support was 4 days (IQR 2-8). Overall survival to decannulation was 78.3% (65% EARLY vs. 88.5% LATE, P = .08) and overall survival to hospital discharge was 58.7% (35% EARLY vs. 76.9% LATE, P = .004). Conclusion Systematic modifications to ECMO support strategy and staff preparation are associated with a significant increase in perioperative survival for pediatric patients requiring post-cardiotomy ECMO support.

Strategi “TAK – JEMPOL (Tertib Administrasi Kependudukan dengan Jemput Bola)” bagi umat Hindu di desa Kayukebek Kecamatan Tutur Kabupaten Pasuruan

Penelitian ini bertujuan mendeskripsikan, menganalisis, dan menginterpretasikan strategi aparatur Desa dalam meningkatkan kesadaran tertib administrasi kependudukan di Desa Kayukebek dengan mengacu pada tipe-tipe strategi menurut Jack Koteen meliputi: Corporate strategy, Program strategy, Resource support strategy, dan Institutional strategy. Penelitian ini menggunakan metode penelitian kualitatif deskriptif. Informan dari penelitian ini adalah Kepala Desa, Sekretaris Desa sebagai pemegang peranan penting dalam keputusan pemerintahan Desa, Kaur bagian pelayanan administrasi kependudukan dan kepala adat umat Hindu sebagai informan kunci yang mengetahui permasalahan yang terjadi, masyarakat sebanyak 1-2 orang sebagai perwakilan dari masing-masing Dusun. Hasil penelitian menunjukkan, pertama kondisi administrasi kependudukan di Desa Kayukebek khususnya kalangan umat Hindu saat ini sudah mulai tertib dimana masyarakat dulunya tidak respon sekarang sudah mulai mengerti dan sadar akan pentingnya administrasi kependudukan. Kedua terdapat beberapa faktor yang menyebabkan warga kurang tertib administrasi kependudukan salah satunya yaitu masyarakat mengeluhkan akan biaya yang mahal, jarak tempuh ke balai desa jauh dan masyarakat kurang memiliki kesadaran dari awal sehingga ketika ada keperluan mendadak saja mereka baru mengurusnya, seperti kebutuhan untuk persyaratan pendaftaran masuk sekolah, pernikahan dan lain sebagainya. Ketiga, strategi aparatur desa dalam meningkatkan kesadaran tertib administrasi kependudukan di kalangan umat Hindu upaya yang dilakukan antara lain dengan mengadakan sosialisasi administrasi kependudukan, pemanfaatan sumber daya manusia, meningkatkan kemampuan aparatur desa untuk melakukan koordinasi dan kerjasama dengan instansi terkait administrasi kependudukan dan mendekatkan pelayanan secara langsung kepada masyarakat

Facilitators and inhibitors to visualising information in organisational practice

<p>The benefits of visual artefacts and methodologies have been well documented in the strategy literature. However, this work has concentrated on the ‘how to do’ and ‘why to do’ of visualisation. It remains unclear why, given this widespread promotion, visualisation is not utilised more for communicating and developing strategy. This thesis explores the ‘doing’ of strategy visualisation through a practice lens by examining the processes through which visualisation services are adopted by organisations. Using a qualitative approach, I studied ten organisations in five countries that create visualisations for clients and identified common facilitators and inhibitors of visualisation adoption, discussing its implications for strategy. The study’s findings expand upon the literature on facilitators and inhibitors to visualisation, discovering that these factors are personal and contextual in nature. Personal factors include: - prospective clients’ experience of prior visualisation outcomes; - predispositions for or against visualisation; - prior knowledge about visualisation and associated services; - partiality towards particular visualisation consultants; and - the capability to distinguish specific organisational needs for visualisation. Contextual factors such as organisational culture, and ability to approve the service within an allocated budget, also influence the adoption of visualisation. Based on a greater understanding of these factors, a heuristic framework was developed to relate these facilitators or inhibitors to four process phases: Pre-contact → Contact → Commitment → and Post-purchase Evaluation. My research findings benefit practitioners, by clarifying facilitating and inhibiting factors to visualisation adoption and suggesting interventions based on these. The findings also have implications for methodology and theory development: they indicate the value of studying strategy visualisation through a practice lens; add to our understanding of how visualisation can clarify and support strategy making; and enable insight into the dynamics of visualisation adoption to provide reasons why visualisation is not as widespread a practice as its proponents suggest it should be.</p>

Feasibility and Clinical Outcomes of a Step Up Noninvasive Respiratory Support Strategy in Patients with Severe COVID-19 Pneumonia

The best noninvasive respiratory strategy in patients with Coronavirus Disease 2019 (COVID-19) pneumonia is still discussed. We aimed at assessing the rate of endotracheal intubation (ETI) in patients treated with continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) if CPAP failed. Secondary outcomes were in-hospital mortality and in-hospital length of stay (LOS). A retrospective, observational, multicenter study was conducted in intermediate-high dependency respiratory units of two Italian university hospitals. Consecutive patients with COVID-19 treated with CPAP were enrolled. Thoraco-abdominal asynchrony or hemodynamic instability led to ETI. Patients showing SpO2 ≤ 94%, respiratory rate ≥ 30 bpm or accessory muscle activation on CPAP received NIV. Respiratory distress and desaturation despite NIV eventually led to ETI. 156 patients were included. The overall rate of ETI was 30%, mortality 18% and median LOS 24 (17–32) days. Among patients that failed CPAP (n = 63), 28% were intubated, while the remaining 72% received NIV, of which 65% were intubated. Patients intubated after CPAP showed lower baseline PaO2/FiO2, lower lymphocyte counts and higher D-dimer values compared with patients intubated after CPAP + NIV. Mortality was 22% with CPAP + ETI, and 20% with CPAP + NIV + ETI. In the case of CPAP failure, a NIV trial appears feasible, does not deteriorate respiratory status and may reduce the need for ETI in COVID-19 patients.
