Proposta di esame PiTrAv per valutare le competenze professionalizzanti nel CL in Fisioterapia: la prospettiva di studenti e tutor clinici.
No full textNel CL in Fisioterapia (CLF) l’esame di tirocinio del III anno deve garantire la competenza professionale.[1] Presso il CLF del nostro Ateneo applichiamo una modalità di esame finale di tirocinio definita PiTrAv. L’acronimo sintetizza le sue tre fasi: Pianificazione, Trattamento, AutoValutazione. Esso valuta l’abilità di risoluzione di un problema clinico e le abilità gestuali e relazionali che gli studenti adottano per risolvere efficacemente un problema in situazione reale. L’indagine qualitativa ha lo scopo di evidenziare le opinioni dei tutor clinici e degli studenti partecipanti all’esame per verificarne la validità “di facciata” in qualità di esame abilitante alla professione fisioterapista. MATERIALI E METODISono stati auto-somministrati dei questionari individuali, anonimi, a risposta aperta breve rivolti agli studenti e ai tutor clinici-valutatori nell’esame PiTrAV. La somministrazione è avvenuta prima della comunicazione agli studenti del voto ottenuto. Le risposte ai questionari sono state analizzate da due fisioterapisti indipendenti, ricorrendo ad un terzo parere in caso di disaccordo. RISULTATIStudenti: PiTrAv è stato giudicato completo e globale, facendo emergere competenze professionali di ragionamento clinico e presa in carico del paziente e rendendo evidenti le competenze mancanti. Le criticità sollevate riguardano l’elevato stress percepito e la emotività vissuta nella situazione. I tempi di esame sono stati giudicati da molti studenti inadeguati per esprimere pienamente le competenze professionali e le abilità di ragionamento clinico. Tutor clinici: PiTrAv è stato giudicato in grado di far emergere competenze professionalizzanti di presa in carico, di ragionamento clinico e relazionali. Le criticità evidenziate riguardano la mancanza di un livello accettabile di performance oggettivo, univoco e condiviso, la durata complessiva dell’esame e l’ingente impegno organizzativo. CONCLUSIONIPiTrAV sembra essere un valido strumento per certificare l’acquisizione di abilità professionalizzanti degli studenti fisioterapisti. Esso misura l’abilità di integrazione delle conoscenze teoriche e tecnico-comportamentali, finalizzata a risolvere problemi attraverso il ragionamento clinico
Pt-TiO<sub>2</sub> Bilayered Hemispherical Nanoshells with Tunable Pt Distribution for Chemically Self-Propelled Colloidal Motors
No full textThe control of colloidal motors’ motion is crucial
for their
practical applications. The modulation of the active component distribution
on the motors is one of the effective routes to controlling their
motion but still in challenge. Here, Pt-TiO2 bilayered
hemispherical nanoshells (BHNSs) with different Pt distributions are
designed and fabricated via etching an organic colloidal template
and depositing TiO2 and Pt in different angles and sequences.
The obtained nanoshells include the BHNSs with complete Pt outer and
inner layers (or TiO2/Pt and Pt/TiO2 BHNSs)
and the partially bilayered hemispherical nanoshells (P-BHNSs) with
incomplete Pt outer and inner layers (or TiO2/Pt and Pt/TiO2 P-BHNSs). All these Pt-TiO2 BHNSs can move, in
H2O2-containing solutions, in Pt coating-pushed
way, exhibiting Pt distribution-dependent motion modes, speeds, and
postures. Typically, the TiO2/Pt (or Pt/TiO2) BHNSs move at the posture of the opening forward (or backward),
exhibiting well-directional motion with a relatively low speed, while
the TiO2/Pt (or Pt/TiO2) P-BHNSs move at the
posture of the opening forward (or backward) with a tilted angle,
showing the quasi-circular motion with a relatively high speed. A
Pt coating catalysis-induced diffusiophoresis mechanism is proposed,
which can well describe the Pt distribution-dependent self-propelled
behaviors. This work provides a flexible route for fabricating Pt
distribution-tunable nanoshells and deepens our understanding of Pt
distribution-dependent chemically self-propelled behaviors

Implementasi Protokol Keamanan Dan Segmentasi Jaringan Dalam Project Pembangunan WLAN Untuk PT Pan Pacific Insurance
No full textSecurity of data and network devices is essential in the development of a computer network, either in the creation of new computer networks or in the development of existing computer networks. PT. Pan Pacific Insurance as a company that holds large amounts of data along with its supporting computer network's infrastructure, focuses on security aspects in addition to performance aspects in its computer network. To get the flexibility of its computer network, the company developed a wireless local area network (WLAN) in line with the relocation of its head office. The Existing company's network needs to be improved with a WLAN network, so it does not only improve employee performance and provides the best security for company data. For those purposes, the authors applied the use of Cisco Wireless LAN Controller (WLC), Cisco Access Point and applied the WPA+WPA2 PSK security protocol for the SSID used by employees. Using this protocol when employees want to connect to the network wireless, they will be forced to type the password that has been set. In addition to implementing the security protocol, the author also applies the Web Policy Authentication security protocol for the SSID used by guests. So that guests who want to connect to a wireless network will be directed to a web browser to be asked to enter a username and password first. A series of security protocols, also added with network segmentation on each SSID to use a different network address. Thus, the essence of network security and performance is expected to increase. From the results of the tests carried out, obtained security guarantees on the PT. Pan Pacific Insurance successfully directs every user connected to the network as part of the security protocol implemented. Furthermore, with network segmentation, user traffic is more controlled because guests get their network segmentation, so they don't interfere with network traffic for users or company staff in company operations
Intérêt de l'analyse histologique rénale pour le diagnostic, le pronostic et le traitement des néphropathies chez le chien et le chat
No full textSur la base des connaissances acquises sur l'histologie rénale pendant ces 40 dernières années, l'examen clinique, les examens de laboratoire et l'imagerie médicale permettent de détecter une maladie rénale et d'établir avec plus ou moins d'exactitude un diagnostic, un pronostic et un traitement adéquats. L'objectif de notre étude est d'évaluer l'intérêt de la biopsie rénale en pratique courante. Elle porte sur 54 chiens et 56 chats atteints de néphropathies diverses. Les syndromes rénaux ont été déterminés avec exactitude dans 77% des cas dans les deux espèces. Les hypothèses lésionnelles n'ont été confirmées que dans 57% des chiens et dans 39% des chats. Les pronostics émis avant/après histologie concordent à 67% chez le chien et à 73% chez le chat. Quant à la thérapeutique, elle a été modifiée, suite au résultat histopathologique, dans 37.5% des cas canins et dans 27.6% des cas félins. La biopsie rénale peut donc apporter un complément d'information important en néphrologie canine et féline
Titanium oxide adhesion layer for high temperature annealed Si/Si3N4/TiOx/Pt/LiCoO2 battery structures
No full textThis work describes the influence of a high annealing temperature of about
700C on the Si(substrate)/Si3N4/TiOx/Pt/LiCoO2 multilayer system for the
fabrication of all-solid-state lithium ion thin film microbatteries. Such microbatteries
typically utilize lithium cobalt oxide (LiCoO2) as cathode material
with a platinum (Pt) current collector. Silicon nitride (Si3N4) is used to act as a
barrier against Li diffusion into the substrate. For a good adherence between
Si3N4 and Pt, commonly titanium (Ti) is used as intermediate layer. However,
to achieve crystalline LiCoO2 the multilayer system has to be annealed at high
temperature. This post-treatment initiates Ti diffusion into the Pt-collector
and an oxidation to TiOx, leading to volume expansion and adhesion failures.
To solve this adhesion problem, we introduce titanium oxide (TiOx) as an
adhesion layer, avoiding the diffusion during the annealing process. LiCoO2,
Pt and Si3N4 layers were deposited by magnetron sputtering and the TiOx
layer by thermal oxidation of Ti layers deposited by e-beam technique. Asdeposited
and annealed multilayer systems using various TiOx layer thicknesses
were studied by scanning electron microscopy (SEM) and time-of-flight
secondary ion mass spectrometry (ToF-SIMS) and x-ray photoelectron spectroscopy
(XPS). The results revealed that an annealing process at temperature
of 700C leads to different interactions of Ti atoms between the layers, for
various TiOx layer thicknesses (25–45 nm).This work was financially supported by FEDER/ COMPETE and FCT funds with the Projects PTDC/ EEA-ELC/114713/2009, PEst-C/QUI/UI0686/2013 and UID/EEA/04436/2013, first author scholarship SFRH/BPD/95905/2013 and second author scholarship SFRH/BD/78217/2011.
