Page as a Visual Story: An Adventure in a Workshop Images Deeply Settled in a Real Space to Promote Cambiano Cityâs (Turinâs Area) Artistic, Cultural and Territorial Heritage and the Distilleria Mazzetti dâAltavilla in Alexandria
What is the meaning each of us want to give to âhis ownâ architecture, âhis ownâ city, âhis ownâ life? And how can we communicate this with a vision and especially through images? Can the âvisual storyâ become a mirror reflecting our culture, our soul? We are going through a historical moment of which reflection on âvisual cultureâ, but even the most widespread practice of the âact of seeingâ, is back to being very contemporary, supported by an ever wider use of images in scientific practice. In this sense, the fundamental role of images in many different disciplines and scientific areas is undeniable, ranging from the culture of vision experienced in the introductory workshop âThe page as a visual narrativeâ, declined in its various applications, from public to private. This workshop ranged between theory and practice, between vision laws and graphic applications for existing work and products, interacting with the customer. The activity carried out a series of practical experiences and reasoning aimed at showing how communication should be planned. The realization of four exhibition panels and four illustrative brochures have put in practice the concept of âvisual narrativeâ to evoke, in the modern communicative reality, the artistic cultural heritage of Cambiano city in Turinâs area and history, products and philosophy of Mazzetti dâAltavilla company in Monferrato
MaxHadoop: An Efficient Scalable Emulation Tool to Test SDN Protocols in Emulated Hadoop Environments
AbstractThis paper presents MaxHadoop, a flexible and scalable emulation tool, which allows the efficient and accurate emulation of Hadoop environments over Software Defined Networks (SDNs). Hadoop has been designed to manage endless data-streams over networks, making it a tailored candidate to support the new class of network services belonging to Big Data. The development of Hadoop is contemporary with the evolution of networks towards the new architectures "Software Defined." To create our emulation environment, tailored to SDNs, we employ MaxiNet, given its capability of emulating large-scale SDNs. We make it possible to emulate realistic Hadoop scenarios on large-scale SDNs using low-cost commodity hardware, by resolving a few key limitations of MaxiNet through appropriate configuration settings. We validate the MaxHadoop emulator by executing two benchmarks, namely WordCount and TeraSort, to evaluate a set of Key Performance Indicators. The tests' outcomes evidence that MaxHadoop outperforms other existing emulation tools running over commodity hardware. Finally, we show the potentiality of MaxHadoop by utilizing it to perform a comparison of SDN-based network protocols
Representing fortified architecture to narrate and enhance the Alexandrian territory border
[EN] The Piemonte cultural territory is also characterized by the significant presence of complex defensive
systems, grouped by types and orographic configuration. Specifically,this paper will address asystematic
and unitary re-reading of the territory of the Alessandria area, which includes: the sixteenth-century Cittadella di Casale, of the Gonzagas; the Citadel of Alexandria (1732), by Giulio Ignazio Bertola; Valenza
and its fortifications (from the âSpanishâ period with interventions by Gaspare Beretta, also interested in
the fort / Castello Tortona); that of Gavi (restored âin the modernâ by Gaspare Maculano known as Fiorenzuola, the friar who condemned Galileo). Following thirty years international research, the objectives
of the work are twofold: the first aims to physically connect in this system a ânetworkâ of thematically
dedicated tourist itineraries, through documentary paths that reconstruct historical events, construction
phases and transformation, (in similitude with the ECCOFORT project, in the province of Verona). Following other works, by the authors already dedicated to the Alexandrian, through the advanced 3D
modeling (like the one carried out in the reconstruction of the fort of Gavi) the second objective of the
present contribution will follow the same restoring and reconstructive procedure. Through digitalized
anastylosis, even dynamized, the Castle of Tortona will be rebuilt on the basis âamong other thingsâ of
the conspicuous documentation (dated 1799, the year of the Napoleonic siege, followed by demolition,
in 1801) found at the Osterreichisches Staatsarchiv, Kriegsarchiv of Vienna. The critical reconstruction
is now made possible thanks to the precious wealth of knowledge, matured over the decades by Marotta,
Zerlenga, Abello: with (indexed) data, including metrics, graphics and visual returns. Drawing between
real and virtual, it will be possible to reconnect individual episodes, comparable and critically selected
information, by means of congruently connected interventions, both physically and digitally. Finally, in
a project of knowledge, conservation and valorisation, the âlocalâ dimension dialogues and integrates
with the European dimension.Marotta, A.; Cirillo, V.; Rabino, C.; Zerlenga, O. (2020). Rappresentare lâarchitettura fortificata per narrare e valorizzare il territorio della frontiera alessandrina.

Effects of an intervention to prevent the bullying in first-grade secondary schools of Palermo, Italy: the BIAS study
Background: Bullying is one of the most common expressions of violence in the peer context during school years.
This study investigates the prevalence of bullying and the short-term effects on studentsâ bullying perceptions of a
preventive intervention conducted among teachers of first-grade secondary schools in Palermo, Sicily (Italy).
Methods: Between the 2017/2018 and 2018/2019 school years, a pre-post intervention study was conducted among
nine school institutions, sampled and categorized by neighbourhood socioeconomic index. A questionnaire investigating
physical, verbal, and indirect bullying, the role of observers, prosociality, and resiliency in bullying was administered before
and after intervention with formative cascade training of the teachers of the selected classes. Three different
methods (sentinel questions, the five-question method, the âscore of sevenâ method) were used to detect the
baseline level of bullying.
Results: A total of 402 students participated in the study (72.7% response rate). A decrease in the number of
bullying episodes after the intervention was reported by the students in all types of bullying explored (physical,
verbal, and indirect bullying, observers, resiliency, and prosociality), with all three methods. In particular, a
statistically significant decrease in all the bullying areas investigated (except for resiliency) was reported for students
attending schools of an intermediate socioeconomic level.
Conclusions: Even if many school-based interventions have been implemented to reduce school bullying throughout
the world, this is one of the first conducted in Europe and it assesses the effectiveness among students of an antibullying intervention tailored for teachers. The encouraging results in reducing the number of bullying episodes together with the low cost in terms of human and economic resources could suggest an extension of this research on a
regional/national scale
THE BIAS (BULLYING IN SICILIAN SCHOOL) PILOT STUDY: INVESTIGATING THE PREVALENCE OF BULLYING IN SCHOOL OF PALERMO CITY. A RESEARCH STUDY PROTOCOL
Being a serious threat to physical and emotional health of children and adolescents all over the world, bullying in school represents an important public health issue. Since 2007, in Italy, the Ministry of Education (MIUR) has promoted activities to face and prevent bullying in schools of all levels while at the same time national and local Health Authorities have implemented effective social-health strategies.
To date, the lack of consistent data needed to properly describe the concerning increase of this Public Health phenomenon prevents both the ability to systematically survey and measure the effectiveness of the public health strategies against bullying.
The Bullying In Sicilian Schools (BIAS) pilot studyâs aims: i) to estimate the prevalence of bullying in a sample of secondary first-grade schools of Palermo, the largest city in Sicily, investigating its characteristics, and ii) to assess the feasibility of alternative methods for the detection of the prevalence of bullying in schools. Here we present the research protocol and the questionnaires that will be used
Laser fluorescence as an alternative for digital radiography in detecting caries lesions: a literature review
O diagnĂłstico das lesĂ”es de cĂĄrie consiste dos mĂ©todos visual/tĂĄtil, pelo Sistema Internacional de Detecção e Avaliação de CĂĄrie (Icdas) e radiogrĂĄfico (BW), no entanto, esses mĂ©todos tĂȘm limitaçÔes para a detecção de cĂĄrie em profundidades e localizaçÔes diferentes e normalmente sĂŁo influenciados pela experiĂȘncia do examinador. Novas tecnologias surgiram para tentar melhorar os mĂ©todos de diagnĂłstico de cĂĄrie, entre el as hĂĄ as que utilizam princĂpios Ăłpticos para quantificar diferenças entre tecidos saudĂĄveis e desmineralizados, por exemplo: a fluorescĂȘncia quantitativa induzida pela luz (QLF); a caneta de detecção de cĂĄrie âDIAGNOdentâ; e o VistaProof (cĂąmera fluorescente). Esta revisĂŁo de literatura tem o objetivo de fornecer informaçÔes atualizadas sobre a aplicabilidade dos mĂ©todos baseados na fluorescĂȘncia no auxĂlio de diagnĂłstico de cĂĄries. Os seguintes resultados sĂŁo: DIAGNOpen foi o mĂ©todo mais eficaz no diagnĂłstico de cĂĄrie, alguns autores indicam que pode ser utilizado como Ășnico mĂ©todo de diagnĂłstico, no entanto, a maioria recomenda utilizar como mĂ©todo complementar ao Icdas e ao BW. A LFpen deve ser utilizada em associação ao Icdas e dois artigos indicam a transiluminação por luz infravermelha prĂłxima (Nilt) como substituta das BW, embora haja necessidade de mais estudos para chegar a uma decisĂŁo concreta. Em conclusĂŁo, os mĂ©todos digitais para o diagnĂłstico de cĂĄrie sĂŁo eficientes, mas nĂŁo substituem os mĂ©todos visual/tĂĄtil e as radiografias bitewing. Portanto devem ser utilizados como mĂ©todos complementares de diagnĂłstico aos jĂĄ conhecidos e amplamente utilizados e estudados.Diagnosis of caries lesions consists of visual/tactile methods following the International Caries Detection and Assessment System (ICDAS) and radiographic methods (BW), however these methods have limitations for detecting caries at different depths and locations and is usually influenced by the examinerâs experience. New technologies have emerged to improve caries diagnosis methods, among these are methods that use optical principles to quantify differences between healthy and demineralized tissues, for example: quantitative light- -induced fluorescence (QLF), the âDIAGNOdentâ caries detection pen, and VistaProof (fluorescence camera). This literature review aims to provide up-to-date information on the applicability of fluorescence-based methods in the diagnosis of caries. The results show that DIAGNOdent pen was the most effective method for diagnosing caries, wherein some authors indicate that it can be used as the only diagnostic method, but most recommend using it as a complementary method to ICDAS and BW. LFpen must be used in association with ICDAS and 2 articles indicate near-infrared light transillumination (NILT) as a substitute for BW, however there is still a need for further studies to reach a concrete decision. In conclusion, digital methods for the diagnosis of caries are efficient, but they do not replace visual/tactile methods and bitewing radiographs. Therefore, they should be used as a complementary diagnostic method to those already known and widely used and studied
âDisegno dal vero e dellâimmaginarioâ: le veritĂ di un ossimoro visivo | âDrawing from Life and Imaginationâ: the Truths of a Visual Oxymoron
ITA - Pare che in alcuni Corsi di Laurea in Architettura le âmagnifiche sorti e progressiveâ della tecnologia digitale sempre piĂč avanzata abbiano generato la quasi totale scomparsa del disegno manuale e tradizionale. Il dominio dellâimmagine digitale, che si impone come nuova forma di comunicazione visiva, regala lâillusione che si possa prescindere dalle forme di rappresentazione tradizionali, tanto da pensare di poterle escludere dal percorso formativo dellâarchitetto. Restando fermi nella convinzione che sia, invece, indispensabile per un architetto avere una solida cultura del Disegno, da quello tradizionale alle modalitĂ piĂč innovative, un contributo prezioso viene fornito dal Workshop di Disegno dal Vero e dellâImmaginario, inserito nei Corsi di Laurea Magistrale in Architettura, presso il Politecnico di Torino. Il nome scelto per questo corso racchiude in sĂ© un evidente ossimoro, nellâottica di conciliare due aspetti apparentemente contraddittori, ma in realtĂ complementari. In unâepoca in cui la comune visione tridimensionale dellâopera dâarte puĂČ essere integrata o sostituita da una realtĂ virtuale, alcuni termini come âfantasticoâ, âimmaginarioâ o âvisionarioâ, assumono una diversa funzione. CosĂŹ, paradossalmente (in architettura e non solo), la rappresentazione della realtĂ âvirtualeâ viene impiegata per meglio rappresentare il âveroâ e la realtĂ . Il presente contributo affronterĂ in prevalenza il secondo approccio proposto nel corso e cioĂš quello dellâimmaginario.
ENG - It seems that in some Degree Courses in Architecture the âmagnifiche sorti e progressiveâ of increasingly advanced digital technology have generated the almost total disappearance of manual and traditional drawing. The dominion of the digital image, which imposes itself as a new form of visual communication, gives the illusion that one can disregard traditional forms of representation, so much so that one thinks one can exclude them from the architectâs educational path. Staying firm in the belief that it is, instead, indispensable for an architect to have a solid culture of Drawing, from the traditional one to the most innovative modalities, the Drawing from Life and Imagination Workshop,
included in the Masterâs Degree Courses in Architecture, at the Polytechnic of Turin, provides a valuable contribution in this sense. The name chosen for this course contains an obvious oxymoron, in order to reconcile two apparently contradictory but actually complementary aspects. In an age when the common three-dimensional vision of the work of art can be integrated or replaced by virtual reality, some terms such as âfantasticâ, âimaginaryâ or âvisionaryâ take on a different function. In this way, paradoxically (in architecture and not only), the representation of âvirtualâ reality is used to better represent the ârealâ and reality. The present contribution will deal mainly with the second approach proposed in the course, namely that of the imaginary

Systemic amyloidosis due to unknown multiple myeloma in small bowel pseudo-obstruction: case report
Amyloidosis is a pathologic diagnosis characterized by extracellular deposition of insoluble protein fibrils in various organs and tissues. There are two main forms of amyloidosis, primary amyloidosis, and secondary amyloidosis. Gastrointestinal involvement is common in both amyloidosis forms. We describe the case of a 78-year-old woman taken to the operating room for small bowel obstruction, found to have pseudo-obstruction and enteritis. Exploratory laparotomy revealed gastric mass and histological examen showed extensive amyloid deposition consistent with amyloidosis. Hematological evaluation revealed unknown multiple myeloma. This case report and literature data suggest to perform a hematological examination in patients with amyloidosis diagnosis to exclude a multiple myeloma or other plasma cell disorder
