Supporting Higher Education—Hospital Transition through Blended Learning

The purpose of this paper is to present two exploratory studies that have a potential for identifying research-based blended learning tools for CBME. The studies focus on the development of a group of medical students’ professional image (in Genova and Rome) during their hospital internship. The paper addresses three related questions: 1. How does their professional representation change in the transition from university to hospital? 2. Which competences emerge from the students’ reports? 3. Which competences are still under represented

From a postcolonial to a transmodern world social forum discourse

The 2013 edition of the World Social Forum took place in Tunis, March 26th-30th. While Mediterranean Education actors rarely refer to Frantz Fanon when challenging the neo-liberal educational agenda, among the Latin American, Asia and African popular education actors there is a noticeable trend to “read” local practice in relation to regional specificities and to endorse the epistemic de-linking and disobedience from the linkages between rationality/modernity and coloniality as advocated by transmodern scholars Quijano and Mignolo.peer-reviewe

Algoritma Kriptografi Aes Rijndael

This paper discusses about AES Rijndael, the cryptography algorithm. The security factor in delivering important information has became awareness for some people. Many ways have been issued to secure the information. One of those ways is by applying encryption using some cryptography algorithms. The algorithm itself has been improved year by year to overcome irresponsible people to get the information easily. The algorithm Rijndael were born in 1997 and chosen as new standard in cryptography world in 2000. This algorithm has been chosen not just for its security, but also because the flexibility and efficiency implementation in many platform

Bilingualism and conversational understanding in young children

The purpose of the two experiments reported here was to investigate whether bilingualism confers an advantage on children’s conversational understanding. A total of 163 children aged 3 to 6 years were given a Conversational Violations Test to determine their ability to identify responses to questions as violations of Gricean maxims of conversation (to be informative and avoid redundancy, speak the truth, and be relevant and polite). Though comparatively delayed in their L2 vocabulary, children who were bilingual in Italian and Slovenian (with Slovenian as the dominant language) generally outperformed those who were either monolingual in Italian or Slovenian. We suggest that bilingualism can be accompanied by an enhanced ability to appreciate effective communicative responses

A shared latent space matrix factorisation method for recommending new trial evidence for systematic review updates

Clinical trial registries can be used to monitor the production of trial evidence and signal when systematic reviews become out of date. However, this use has been limited to date due to the extensive manual review required to search for and screen relevant trial registrations. Our aim was to evaluate a new method that could partially automate the identification of trial registrations that may be relevant for systematic review updates. We identified 179 systematic reviews of drug interventions for type 2 diabetes, which included 537 clinical trials that had registrations in ClinicalTrials.gov. We tested a matrix factorisation approach that uses a shared latent space to learn how to rank relevant trial registrations for each systematic review, comparing the performance to document similarity to rank relevant trial registrations. The two approaches were tested on a holdout set of the newest trials from the set of type 2 diabetes systematic reviews and an unseen set of 141 clinical trial registrations from 17 updated systematic reviews published in the Cochrane Database of Systematic Reviews. The matrix factorisation approach outperformed the document similarity approach with a median rank of 59 and recall@100 of 60.9%, compared to a median rank of 138 and recall@100 of 42.8% in the document similarity baseline. In the second set of systematic reviews and their updates, the highest performing approach used document similarity and gave a median rank of 67 (recall@100 of 62.9%). The proposed method was useful for ranking trial registrations to reduce the manual workload associated with finding relevant trials for systematic review updates. The results suggest that the approach could be used as part of a semi-automated pipeline for monitoring potentially new evidence for inclusion in a review update.Comment: Journal of Biomedical Informatics Vol. 79, March 2018, p. 32-4

Validasi Paket Program Nodal3 Untuk Kasus Statis Benchmark Teras Reaktor Pwr

VALIDASI PAKET PROGRAM NODAL3 UNTUK KASUS STATIS TERAS BENCHMARK REAKTOR PWR. Persamaan difusi neutron dengan metode nodal telah menjadi metode standar dalam perhitungan parameter neutronik teras reaktor daya air ringan, seperti reaktor air bertekanan (PWR) atau air mendidih (BWR), karena waktu komputasi yang cepat dan hasilnya akurat. Paket program NODAL3 telah dikembangkan untuk menyelesaikan persamaan difusi neutron dengan metode nodal polinom (PNM) dalam geometri 3-dimensi (3-D). Validasi hasil perhitungan NODAL3 untuk kasus statis teras benchmark reaktor PWR (Pressurized Water Reactor), seperti IAEA-2D, BIBLIS, KOEBERG dan IAEA-3D, disajikan dalam penelitian ini. Teras benchmark yang dipilih mewakili kasus 2-D dan 3-D dan mempunyai karaktristik yang berbeda, sehingga dapat menentukan keakuratan NODAL3 dari aspek neutronik yang luas. Parameter neutronik statis yang dihitung adalah faktor perlipatan efektif, keff, faktor puncak daya (FPD) dan profil distribusi FPD ke arah aksial. Dibandingkan dengan acuan, hasil perhitungan NODAL3 menunjukkan bahwa untuk nilai keff terdapat perbedaan maksimum sebesar 0,006% (Δk). Sedangkan untuk FPD radial dan FPD aksial maksimum, selisih maksimum dengan acuan masing-masing sebesar -0,006 dan 0,051. Untuk kasus 3-D, hasil perhitungan NODAL3 konsisten dengan hasil perhitungan paket program nodal tervalidasi PARCS dan NESTLE. Riset ini menunjukkan bahwa akurasi paket program NODAL3 dalam menghitung parameter neutronik teras benchmark reaktor PWR, baik kasus 2-D dan 3-D, menunjukkan hasil yang sangat memuaskan. Oleh karena itu, paket program NODAL3 siap untuk diaplikasikan dalam analisis neutronik reaktor PWR yang riil

Efecto del Tratamiento Térmico Post-Soldadura sobre la Microestructura y las Propiedades Mecánicas de un Acero 9Cr Depositado por FCAW

Los aceros 9Cr tienen suma importancia en la industria de generación termoeléctrica debido a sus marcadas resistencias al creep y a la corrosión. La soldabilidad de estas aleaciones es un punto crítico dado que encuentran diversas aplicaciones en equipos de construcción soldada. Las propiedades mecánicas requeridas se logran luego de un tratamiento térmico post soldadura (PWHT). Este trabajo estudió el efecto del PWHT sobrela microestructura y las propiedades mecánicas de soldaduras 9Cr utilizando un alambre tubular flux-coredexperimental, mediante un proceso semiautomático bajo protección de gas Ar-20%CO2. Se realizaron PWHT adiferentes temperaturas y tiempos. Se analizó la composición química y se realizaron ensayos de tracción adistintas temperaturas, ensayos de impacto tipo Charpy-V y de microdureza Vickers. Se estudiaron lasmicroestructuras mediante difracción de rayos X (XRD), microscopía óptica (OM) y electrónica de barrido(SEM). En todos los casos se detectó una matriz martensítica con presencia de precipitados inter eintragranulares. En la condición como soldado (AW) se halló ferrita-δ. Se comprobó que la dureza cayó y laenergía de impacto aumentó con el PWHT. La mayor resistencia a alta temperatura se logró con un PWHT desolubilizado a 1150°C y un doble revenido a 660°C
