Venere Ferraro 한국디자인학회 2015 한국디자인학회 학술발표대회 논문집 Vol.2015 No.10

In this paper a case study of a device for diabetic children is analyzed. It concerns a new interactive product system able to make children independent in the disease’s management and to meet the parents’ needs to be updated on their child’s health condition. Author tried to understand how a product experience should be in the field of well-being and then set how to design that product thanks to a methodology based on user-oriented approach, emotional design and interaction design. Author found that designing for the field of well-being requires a design approach that allows for designers to understand: (i) the user the product is designed for, (ii) the context in which the product is used, (iii) which aesthetic features the product should have (iv) how the product should interact with the user and then (v) to evaluate the results on the user himself.

A parametric analysis of the flutter instability for long span suspension bridges

Como, M.,Ferraro, S. Del,Grimaldi, A. Techno-Press 2005 Wind and Structures, An International Journal (WAS Vol.8 No.1

A simplified analysis able to point out the most relevant geometrical and aerodynamic parameters that can influence the flutter of long span modern bridges is the aim of the paper. With this goal, by using a continuous model of the suspension bridge and by a quasi stationary approach, a simple formula of the combined vertical/torsional flutter wind speed is given. A good agreement is obtained comparing the predictions from the proposed formula with the flutter speeds of three modern suspension or cable stayed bridges: the Great Belt East Bridge, the Akashi and Normandie bridges. The paper ends with some comments and comparisons with the well known Selberg formula.

Background and Purpose The respiratory manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been extensively documented. There is emerging evidence that coronavirus disease 2019 (COVID-19) has number of other presenting features which might not be related to the severity of the respiratory disease. We have previously described a case of hypoactive delirium as the first manifestation of COVID-19 without profound lung disease. Here we present five cases of elderly patients, without a prior history of dementia and had no overt COVID-19-related pneumonia, who presented with the acute onset of delirium as the primary manifestation of COVID-19. Methods This retrospective, single-center study performed a health informatics search to produce a list of patients who were admitted with acute confusion and tested positive for the SARS-CoV-2 virus between March 1 and June 30, 2020. The electronic medical admission notes were screened for all patients with confusion who tested positive for SARS-CoV-2. Patients with a history of dementia and a high risk of delirium were excluded, such as severe COVID-19-related pneumonia or any other infection, malignancy, drugs, or severe illness of any kind. Results During the first wave of the COVID-19 pandemic our hospital experienced just over 3,000 SARS-CoV-2 positive patients, and 45 of them had documented confusion upon admission. Secondary causes for their acute confusion were excluded. Five patients were identified as having delirium as the initial presentation of COVID-19-related illness without significant COVID-19-related pneumonitis. None of them had overt chest symptoms or a previous history of confusion, and the 3 patients who underwent head CT scans had normal findings. Conclusions This case series illustrates the importance of recognizing acute confusion as the first manifestation of COVID-19 in susceptible individuals

Advances in Precipitation Measurements and Sciences

신동빈,Ziad Haddad,Ralph Ferraro 한국기상학회 2020 Asia-Pacific Journal of Atmospheric Sciences Vol.56 No.4

The International Precipitation Working Group (IPWG) is one of the science groups to improve satellite system utilization within the Coordination Group for Meteorological Satellites (CGMS) sponsored by the World Meteorological Organization (WMO). IPWG is interested in quantitative precipitation measurements from operational and research perspectives. Its endeavor is to foster the development of better precipitation measurements, the improvement of scientific understanding of the related processes, and the development of international partnerships. IPWGorganizes the series ofworkshops every 2-years to exchange recent scientific issues, gather opinions and recommendations on new and ongoing satellite missions for precipitation and specifically advice CGMS. The 9th workshop of IPWGwas held in November 2018 in Yonsei University, Seoul, Korea. The workshop consisted of major topics including new and ongoing satellite programs, retrieval algorithms, validations of various precipitation products, precipitation science in meteorology, hydrology, oceanography, climate, emerging applications such as health, flood and drought monitoring, and risk assessments. The workshop also featured three interactive sessions, during which the attendees were invited to participate in discussing and making plans to address important issues for IPWG. Two interactive sessions dealt with the IPWG-the Global Water and Energy Experiment (GEWEX) Data and Assessment Panel (GDAP) assessment of global precipitation products. One interactive session was devoted to “looming challenges” to the production of global satellite precipitation estimates. Intensive meetings of the working groups on Research, Validation, Data assimilation and scattering, and Applications followed. In parallel to the workshop, a satellite data training event was held. The separate training activity focused on new and emerging satellite technologies, sensors, and precipitation datasets. The workshop included 69 oral presentations and 47 posters to share precipitation related sciences and applications to the scientific community. As a part of the workshop efforts, the special issue “Advances in Precipitation Measurements and Sciences” is published. We would like to thank all the participants to the 9th workshop of IPWG and for the contributions to this special issue.

The oval technique for nipple-areolar complex reconstruction

Vozza, Amalia,Larocca, Fabio,Ferraro, Giuseppe,Nicoletti, Giovanni Francesco,D'Andrea, Francesco Korean Society of Plastic and Reconstructive Surge 2019 Archives of Plastic Surgery Vol.46 No.2

Background Nipple-areolar complex (NAC) reconstruction is the final stage of breast reconstruction. Ideal reconstruction of the NAC requires symmetry in position, size, shape, texture, pigmentation, and permanent projection, and although many technical descriptions of NAC reconstruction exist in the medical literature, there is no gold standard technique. The technique devised by the authors is very versatile, with excellent results, and it enables 1-step reconstruction with optimal results in terms of shape and nipple projection. Methods Our technique consists of a combination of modified local flaps and a full-thickness skin graft. Patients were observed for 18 months to estimate the amount of retraction. This procedure was performed in 40 patients, four of them bilaterally. The duration of the follow-up was 30 months. Complications occurred in 10% of patients, and included infections (5%), ischemia (2.5%), and hematoma (2.5%). Results No cases of total nipple necrosis were reported. The NAC shape remained optimal in all cases, with a very small reduction of the vertical and horizontal diameters of the areola, which maintained its designed round shape well, and negligible retraction in the diameter and projection of the nipple. Conclusions The oval technique represents a major step forward, involving a combination of existing techniques, such as the C-V flap and the cutaneous graft, to achieve excellent results regarding areola shape and nipple projection, significantly reducing the cases of nipple ischemia. These results were substantially obtained through subcutaneous equatorial sutures, skin grafting, and flattening of the apexes of the flap.

Off‐axis self‐reference digital holography in the visible and far‐infrared region

Vittorio Bianco,Melania Paturzo,Andrea Finizio,Pietro Ferraro 한국전자통신연구원 2019 ETRI Journal Vol.41 No.1

Recent advances in digital holography in the far‐infrared region of the spectrum have demonstrated the potential use of digital holography in homeland security as a tool to observe hostile environments in which smoke, flames, and dust impair vision. However, to make this application practical, it is necessary to simplify the optical setup. Here, we show an off‐axis, self‐reference scheme that spills the reference beam out from the object beam itself and avoids the need for a complex interferometric arrangement. We demonstrate that this scheme allows the reconstruction of high‐quality holograms of objects captured under visible as well as far‐infrared light exposure. This could pave the way to the industrialization of holographic systems to enable users to see through fire. Moreover, the quantitative nature of the holographic signal is preserved. Thus, the reported results demonstrate the possibility to use this setup for optical metrology.

Effects of Grain Refinement on the Microstructure, Mechanical Properties and Reliability of AlSi7Cu3Mg Gravity Die Cast Cylinder Heads

Giulio Timelli,Giordano Camicia,Stefano Ferraro,Roberto Molina 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.4

The effects of grain refinement on the microstructure and mechanical properties of a secondary AlSi7-Cu3Mg gravity die cast cylinder head are reported. Metallographic and image analysis techniques havebeen used to quantitatively examine the macro- and microstructural changes occurring with the addition ofgrain-refining agent. The results indicate that the AlTi5B1 addition produces a fine and uniform grainstructure throughout the casting; this effect is more pronounced in the slowly solidified regions. The initialcontents of Ti and B, which are present as impurity elements in the supplied secondary alloy ingots,are not sufficient to produce effective grain refinement. Under the present casting conditions, the combinedaddition of AlTi5B1 and Sr does not produce any reciprocal interaction or effect on primary α-Aland eutectic solidification. Grain refinement improves the mechanical properties of the as-cast AlSi7Cu3Mgalloy and produces higher Weibull moduli, thus increasing the reliability of the casting. For automotivestructural components, this could be considered an increase in safety.

PROBING THE ROLE OF DYNAMICAL FRICTION IN SHAPING THE BSS RADIAL DISTRIBUTION. I. SEMI-ANALYTICAL MODELS AND PRELIMINARY<i>N</i>-BODY SIMULATIONS

Miocchi, P.,Pasquato, M.,Lanzoni, B.,Ferraro, F. R.,Dalessandro, E.,Vesperini, E.,Alessandrini, E.,Lee, Y.-W. IOP Publishing 2015 The Astrophysical journal Vol.799 No.1

<P>We present semi-analytical models and simplified N-body simulations with 10(4) particles aimed at probing the role of dynamical friction (DF) in determining the radial distribution of blue straggler stars (BSSs) in globular clusters. The semi-analytical models show that DF (which is the only evolutionary mechanism at work) is responsible for the formation of a bimodal distribution with a dip progressively moving toward the external regions of the cluster. However, these models fail to reproduce the formation of the long-lived central peak observed in all dynamically evolved clusters. The results of N-body simulations confirm the formation of a sharp central peak, which remains as a stable feature over time regardless of the initial concentration of the system. In spite of noisy behavior, a bimodal distribution forms in many cases, with the size of the dip increasing as a function of time. In the most advanced stages, the distribution becomes monotonic. These results are in agreement with the observations. Also, the shape of the peak and the location of the minimum (which, in most of cases, is within 10 core radii) turn out to be consistent with observational results. For a more detailed and close comparison with observations, including a proper calibration of the timescales of the dynamical processes driving the evolution of the BSS spatial distribution, more realistic simulations will be necessary.</P>
