One-Step Ethanol Ablation of Viscous Cystic Thyroid Nodules

Abstract: OBJECTIVE. The purpose of this study was to evaluate the efficacy and safety of one-step ethanol ablation in the management of viscous cystic thyroid nodules.MATERIALS AND METHODS. Viscous cystic thyroid nodules are defined as nodules that cannot be aspirated with an 18-gauge needle. Nine euthyroid patients underwent one-step ethanol ablation of benign single compressive viscous cystic thyroid nodules (cystic portion > 90%). The thick content of the nodules was removed with either a 16-gauge needle (n = 8) or an 8.5-French pigtail catheter (n = 1) connected to a suction pump. An injection of 99% sterile ethanol then was administered. After 10 minutes, all of the injected ethanol was withdrawn. Additional treatment was prescribed if the cystic portion of the nodule remained larger than 1 mL. Follow-up sonography was performed 1 and 6 months after treatment. At each follow-up examination, nodule volume, symptom score (centimeter visual analog scale, 0–10), cosmetic grade (grade 1–4), and complications were ...

A Bahadur Representation of the Linear Support Vector Machine

Abstract: The support vector machine has been successful in a variety of applications. Also on the theoretical front, statistical properties of the support vector machine have been studied quite extensively with a particular attention to its Bayes risk consistency under some conditions. In this paper, we study somewhat basic statistical properties of the support vector machine yet to be investigated, namely the asymptotic behavior of the coefficients of the linear support vector machine. A Bahadur type representation of the coefficients is established under appropriate conditions, and their asymptotic normality and statistical variability are derived on the basis of the representation. These asymptotic results do not only help further our understanding of the support vector machine, but also they can be useful for related statistical inferences.

Building Ontology to Implement the BIM (Building Information Modeling) Focused on Pre-Design Stage

Abstract: Pre-planning stage is a most important stage to determine the success of the project throughout the construction lifecycle. Therefore, all information generated from the pre-planning stage must be processed and retained in the format which all the project participants can share. Furthermore, using object-oriented attributes and meta-data in BIM (Building Information Modeling) for easy control of the space objects are actively being studied. This paper investigates ontology and its description logic (OWLDL) and establishes it in the pre-planning stage of construction project and will also carry out a case study based on a real project in Korea. The special objects will be created and the relationship of these special objects will be defined. An ontology diagram will be suggested that will control the special objects with the constraints applied.

Method for Evaluating the Security Risk of a Website Against Phishing Attacks

Abstract: As Internet technologies evolve, phishing and pharming attacks frequently occur and diversify. In order to protect the economic loss and privacy of Internet users against the phishing attacks, several researches such as website authentication and email authentication have been studied. Although, most of them use website black-list (WBL) or website white-list (WWL), there are several weak points, such as validity of WBL DB (database) and the short life-cycle of phishing websites. That is, it is impossible to discriminate between legitimate and forged websites until the phishing attacks are detected and recorded into WBL DB. Furthermore, the existing WBL and WWL approaches hardly counter the new generation of sophisticated malware pharming attacks. In this paper, in order to overcome the limitation of WBL and WWL approaches, new approach based on the WWL approach, which can quantitatively estimate the security risk of websites that is security risk degree representing the phishing websites, is proposed.

Spontaneous rupture of the lateral thoracic artery in patients with liver cirrhosis

Abstract: Bleeding in patients with liver cirrhosis is primarily caused by gastroesophageal varix in association with extensive collateral circulation, portal hypertensive gastropathy, a Mallory-Weiss tear and peptic ulcer disease. The spontaneous rupture of an artery, as a result of coagulopathy, is extremely rare in patients with liver cirrhosis; however, we recently observed a case of a spontaneous rupture of the lateral thoracic artery in a 47 year-old male patient with alcoholic liver cirrhosis. The patient expired despite repeated transcatheter arterial embolization of the lateral thoracic artery and best supportive care. This is, to our knowledge, the first documented case of the spontaneous rupture of the lateral thoracic artery in a patient with liver cirrhosis.

Haematological parameters and respiratory function in diploid and triploid Far Eastern catfish, Silurus asotus

Abstract: Haematological features pertaining to aerobic capability were compared between diploid and triploid specimens of the Far Eastern catfish, Silurus asotus. No significant differences between diploids and triploids were found for the haematocrit value, total haemoglobin, and mean corpuscular haemoglobin concentration, while the mean corpuscular volume, mean corpuscular haemoglobin, and plasma glucose concentration were significantly higher in triploids than in diploids, and the number of red blood cells was significantly lower in triploids than in diploids. The oxygen consumption rate did not differ significantly between diploid and triploid fish ( P>0.05). Nevertheless, the respiratory frequency was higher in triploids than in diploids ( P< 0.05). Triploids were characterized by a lower concentration of circulating blood cells, and aquaculture practice should consider the need for a lower surface to volume ratio.

Performance of cellular phones with video telephony in the use of automated external defibrillators by untrained laypersons

Abstract: Aim: To evaluate the hypothesis that using an automated external defibrillator (AED) with video telephony-directed cellular phone instructions for untrained laypersons would increase the probability of successful performance of AEDs. Real-time communication with visual images can provide critical information and appropriate instructions to both laypersons and dispatchers. Methods: A prospective observational study was undertaken. 52 public officers with no previous experience in the use of a defibrillator were presented with a scenario in which they were asked to use an AED on a manikin according to the instructions given to them by cellular phones with video telephony. The proportion who successfully delivered a shock and the time interval from cardiac arrest to delivery of the shock were recorded. Results: Placement of the electrode pads was performed correctly by all 52 participants and 51 (98%) delivered an accurate shock. The mean (SD) time to correct shock delivery was 131.8 (20.6) s (range 101–202). Conclusion: Correct pad placement and shock delivery can be performed using an AED when instructions are provided via video telephone because a dispatcher can monitor every step and provide correct information.
