Purpose: The purpose of this study was to validate the role of the total malignancy score (TMS)in identifying thyroid nodules suspicious for malignancy through the sum of their ultrasoundfeatures. Methods: The local ethical committee approved this prospective observational study. Weexamined 231 nodules in 231 consecutive patients (164 females and 67 males; age range, 20 to87 years; median age, 59 years; interquartile range, 48 to 70 years) who underwent ultrasoundfollowed by fine-needle aspiration cytology (FNAC). The nodules were further classified usingthe TMS, which considers ultrasound features (number, echogenicity, structure, halo, margins,Doppler signal, calcifications, and growth), and the Bethesda System for Reporting ThyroidCytopathology (TBSRTC), which considers cytological features. Patients with non-negativenodules (TBSRTC categories III to VI) underwent histological analysis, repeated FNAC, or 2years of regular ultrasound follow-up. The associations between the final diagnosis, each of theultrasound features, and the TMS were estimated using the chi-square test, the Mann-WhitneyU test, and multivariate logistic regression. A receiver operating characteristic (ROC) curve wasused to evaluate the diagnostic accuracy of the TMS. Results: On ultrasound, 47% of the nodules (108 of 231) had a TMS <3, 18% (42 of 231) hada TMS of 3, and 35% (81 of 231) had a TMS >3. The FNAC results of 85% of the nodules (196of 231) were benign, while 15% (35 of 231) had non-negative results. Hypoechogenicity, solidstructure, the presence of microcalcifications, and the number of nodules were independentpredictors of the final diagnosis, and the diagnostic accuracy of the TMS was good (area underthe ROC curve, 0.82). Conclusion: The TMS system is simple to use, reliable, easily reproducible, and closely reflectsmalignancy risk. Based on our results, FNAC could be limited to nodules with a TMS ≥3 withoutmissing any cases of carcinoma.

The Immune System in Irritable Bowel Syndrome

( Giovanni Barbara ),( Cesare Cremon ),( Giovanni Carini ),( Lara Bellacosa ),( Lisa Zecchi ),( Roberto De Giorgio ),( Roberto Corinaldesi ),( Vincenzo Stanghellini ) 대한소화기기능성질환·운동학회(구 대한소화관운동학회) 2011 Journal of Neurogastroenterology and Motility (JNM Vol.17 No.4

The potential relevance of systemic and gastrointestinal immune activation in the pathophysiology and symptom generation in the irritable bowel syndrome (IBS) is supported by a number of observations. Infectious gastroenteritis is the strongest risk factor for the development of IBS and increased rates of IBS-like symptoms have been detected in patients with inflammatory bowel disease in remission or in celiac disease patients on a gluten free diet. The number of T cells and mast cells in the small and large intestine of patients with IBS is increased in a large proportion of patients with IBS over healthy controls. Mediators released by immune cells and likely from other non-immune competent cells impact on the function of enteric and sensory afferent nerves as well as on epithelial tight junctions controlling mucosal barrier of recipient animals, isolated human gut tissues or cell culture systems. Antibodies against microbiota antigens (bacterial flagellin), and increased levels of cytokines have been detected systemically in the peripheral blood advocating the existence of abnormal host-microbial interactions and systemic immune responses. Nonetheless, there is wide overlap of data obtained in healthy controls; in addition, the subsets of patients showing immune activation have yet to be clearly identified. Gender, age, geographic differences, genetic predisposition, diet and differences in the intestinal microbiota likely play a role and further research has to be done to clarify their relevance as potential mechanisms in the described immune system dysregulation. Immune activation has stimulated interest for the potential identification of biomarkers useful for clinical and research purposes and the development of novel therapeutic approaches.

The Mixmaster Model as a Cosmological Framework and Aspects of its Quantum Dynamics

Giovanni Imponente,Giovanni Montani 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.42 No.III

This paper provides a review of some recent issues on the Mixmaster dynamics concerning the features of its stochasticity. After a description of the geometrical structure characterizing the homogeneous cosmological models in the Bianchi classification and the Belinsky-Khalatnikov-Lifshitz piecewise representation of the types VIII and IX oscillatory regime, we face the question regarding the time covariance of the resulting chaos as viewed in terms of continuous Misner-Chitr\'e like variables. Finally, we show how in the statistical mechanics framework the Mixmaster chaos raises as semiclassical limit of the quantum dynamics in the Planckian era.

A Study on Improving the Security Vulnerabilities of Modbus-Based SCADA Control Systems

Giovanni A. Cagalaban,Seoksoo Kim,Kyung-jae Ha 한국산학기술학회 2009 한국산학기술학회 학술대회 Vol.- No.-

SCADA control systems and protocols are developed based on reliability, availability, and speed but with no or little attention paid to security. Specifically in Modbus protocol, there are inherent security vulnerabilities in their design. The lack of common security mechanisms in the protocol such as authentication, confidentiality and integrity must be addressed. In this paper, security vulnerabilities of Modbus-based SCADA controls systems will be studied. An in-depth analysis of the message frame formats being sent between master and slave will be discussed to expose the security vulnerabilities. This will enable SCADA users to find ways to fix the security flaws of the protocol and design mitigation strategies to reduce the impact of the possible attacks. Security mechanisms are recommended to further enhance the security of SCADA control systems.

COMPARISON OF TWO MULTIPHASE PROCEDURES ON A COMMERCIAL VEHICLE IN RAIN CONDITIONS

Giovanni Lombardi,Antonio Ercoli,Marco Maganzi,Giacomo de Angeli 한국자동차공학회 2019 International journal of automotive technology Vol.20 No.6

In automotive design, the study of the water thin layer over a car due to rain is becoming increasingly important: the challenge is to obtain a way to describe the behavior of the water over a vehicle in rainy conditions and its interactions with wipers and drainage systems, to determine potential failures of the vehicle design. In this paper two similar numeric procedures have been realized with the software STAR CCM+® to analyze the dynamic of water thin layer starting from the impingement of the rain on the car surface and taking into account even the motion of the wipers over the windshield. Moreover, the water that flows through the drainage systems is monitored to figure out if the water could produce a malfunction of components near them. In order to describe each status of the water, many multiphase models are used. These methodologies have been applied on a commercial vehicle model and the results have been examined and compared to each other. The analysis shows a better description of the reality for one of them, leading to the possibility of using it as a design tool in the automotive industry.

Minimally invasive image-guided thermal ablation is becoming increasingly common as an alternative to surgery for the treatment of benign thyroid nodules. Among the various techniques for thermal ablation, laser ablation (LA) is the least invasive, using the smallest applicators available on the market and enabling extremely precise energy deposition. However, in some cases, multiple laser fibers must be used simultaneously for the treatment of large nodules. In this review, the LA technique is described, and its main clinical applications and results are discussed and illustrated.

Current Definition of and Controversial Issues Regarding Postoperative Pancreatic Fistulas

Giovanni Marchegiani,Stefano Andrianello,Roberto Salvia,Claudio Bassi 거트앤리버 소화기연관학회협의회 2019 Gut and Liver Vol.13 No.2

The International Study Group for Pancreatic Fistula (ISGPF) made the first attempt to standardize the outcome measure of fistulas in the field of pancreatic surgery by publishing the definition and classification of postoperative pancreatic fistulas (POPFs) in 2005. POPFs were determined by any measurable volume of fluid output via an operatively placed drain with amylase activity greater than three times the upper normal serum value. Taking into account more than 10 years of reported experience worldwide, the updated definition published in 2016 by the reconvened International Study Group for Pancreatic Surgery (ISGPS) attempted to overcome the limits of the previous classification. The crucial concept of POPF clinical significance was introduced by eliminating grade A from the fistula scenario. The wider use of interventional procedures has also made it necessary to recode grade C POPFs, which now have clearer boundaries, toward the worst end of the severity scale. Grade B still represents the most prevalent and heterogeneous category of POPFs, both in terms of clinical burden and management. In the near future, further efforts will be required to better stratify grade B POPFs to standardize treatment strategies and compare outcomes among institutions.

An Indoor Positioning Method using IEEE 802.11 Channel State Information

Giovanni Escudero,Jun Gyu Hwang,Joon Goo Park 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.3

In this paper, we propose an indoor positioning system that makes use of the attenuation model for IEEE 802.11 Channel State Information (CSI) in order to determine its distance from an Access Point (AP) at a fixed position. With the use of CSI, we can mitigate the problems present in the use of Received Signal Strength Indicator (RSSI) data and increase the accuracy of the estimated mobile device’s location. For the experiments we performed, we made use of the Intel 5300 Series Network Interface Card (NIC) in order to receive the channel frequency response. The Intel 5300 NIC differs from its counterparts in that it can obtain not only the RSSI but also the CSI between an access point and a mobile device. We can obtain the signal strengths and phases from subcarriers of a system which in turn means making use of this data in the estimation of a mobile device’s position.
