A hemangiosarcoma in a 30 kg, 6-year-old German Shepherd dog showing signs of abdominal distension, anorexia and depression was diagnosed with clinicopathologic examination, abdominal radiographs and ultrasonographic assessmint. In abdominal radiographs, overall abdominal distension was seen. Stomach and some parts of small intestines were deviated caudo-ventrally by enlarged liver. The splenomegaly was also identified and descending colon was dislocated laterally by splenic mass. In ultrasonographic findings, abdominal fluid was identified. Hepatomegaly was seen and it was consisted of multiple, anechoic cysts. The spleen was enlarged and a large round mass with mixed echo pattern at the mid to tail portion of spleen was identified. Grossly, at necropsy, multi-sized cysts in which contained blood and fibrpus materials and some blood were seen in the cross section and it showed hard consistency. Also, lots of small red tumor nodules were dispersed on the serosal surface of the bladder, omentum, mesentery, diaphragm and peritoneum. In abdominal paracentesis, fluid having almost the same properties as circulating blood was identified. The hemoperitoneum was thought to be resulted from the bleeding into peritoneum owing to the rupture of cystic lesions located on the superficial liver area.

At the conclusion of a double-blinded, randomized clinical trial of propranolol hydrochloride, but before un blinding, the patients and clinic personnel were asked to guess the treatment group assignment of each patient. While 79.9% of the patients receiving propranolol correctly Identified their treatment group assignment, 57.2% of the patients receiving placebo incorrectly guessed that they were aiso in the propranolol group. No specific mechanism was identified to explain why more patients receiving propranolol were better able to guess' their group assignment. Clinic physicians correctly identified the group assignment of 69.9% of the patients receiving propranolol and 68.8% of the patients receiving placebo. Clinic coordinators correctly identified the group assignment of 67.1% of the patients receiving propranolol and 70.6% of the patients receiving placebo. For clinic personnel, heart rate level and heart rate change seem to be the mechanisms employed to Identify their patients' treatment assignment.

This paper presents a computational method for a confidence region of identified parameters which are affected by measurement noise and error contained in prescribed parameters. The method is based on sensitivities of the identified parameters with respect to model parameter error and measurement noise along with the law of error propagation. By conducting numerical experiments on simple models, it is confirmed that the confidence region coincides well with the results of numerical experiments. Furthermore, the optimum arrangement of sensor locations is evaluated when uncertainty exists in prescribed parameters, based on the concept that square sum of coefficients of variations of identified results attains minimum. Good agreement of the theoretical results with those of numerical simulation confirmed validity of the theory.

The properties of a scale-free network are little known; its node degree following a power-law distribution is among its few known properties. By selecting real-field scale-free networks from a network dataset and comparing them to other networks, such as random and non-scale-free networks, the topology characteristics of scale-free networks are identified. The assortative coefficient is identified as a key metric of a scale-free network. It is also identified that most scale-free networks have negative assortative coefficients. Traditional generation models of scale-free networks are evaluated based on the identified topology characteristics. Most representative models, such as BA and Holme&Kim, are not effective in generating real-field scale-free networks. A link-rewiring method is suggested that can control the assortative coefficient while preserving the node degree sequence. Our analysis reveals that it is possible to effectively reproduce the assortative coefficients of real-field scale-free networks through link-rewiring.

During the extensive survey of the prokaryotic species diversity in Korea, bacterial strains belonging to Betaproteobacteria and Epsilonproteobacteria were isolated from various sources including freshwater, sediment, soil and fish. A total of 23 isolates were obtained, among which 22 strains were assigned to the class Betaproteobacteria and one strain to the class Epsilonproteobacteria. The 22 betaproteobacterial strains were further assigned to Comamonadaceae (11 strains), Burkholderiaceae (6 strains), Oxalobacteraceae (2 strains), Neisseriaceae (1 strain) and unclassified family groups (2 strains). For the strains of Burkholderiaceae, 3 strains were identified as 3 species of Burkholderia, and 2 strains were as 2 species of Cupriavidus. For the strains of Comamonadaceae, 4 strains were identified as 2 species of the genus Hydrogenophaga, 2 strains as 2 species of Acidovorax, 2 strains as 2 species of Limnohabitans, and each of the remaining strains as single species of Comamonas, Curvibacter and Rhodoferax, respectively. For the strains of Oxalobacteraceae, 1 strain was identified as a species of Undibacterium, and the other strain as a species of Herbaspirillum. The strain belonging to Neisseriaceae was identified as a species of Iodobacter. The remaining strains of Betaproteobacteria were identified as species of Sphaerotilus and Methylibium respectively (family unassigned). The epsilonproteobacterial strain was identified as a species of Arcobacter of the family Camplyobacteraceae. The detailed description of each unrecorded species is provided.

Purpose: The purpose of the study was to describe psychosocial difficulties experienced by cancer patients. Methods: Three focus group interviews were conducted to collect the data from 19 outpatients with cancer undergoing treatments during 2009. All interviews were audio-recorded and transcribed verbatim. The data were analyzed using constant comparative analysis of grounded theory. Results: As a result of constant comparative analysis, 'psychosocial distress' was identified as a core category, and seven subcategories were identified. 'Plunged into negative emotions' and 'damaged self-identity' were identified as major categories in the individual dimension. 'Difficulty in dealing with diagnosis' and 'hasty expectations and concerns' were identified in the dimension of family. 'Inefficient communication' and 'lack of necessary information' were identified in the dimension of health care setting. 'Lonely journey into a strange territory' was identified in the dimension of society. Conclusion: The results of the study indicate that cancer patients experience a wide range of psychosocial problems. Thus, in assessing and relieving psychosocial distress of cancer patients, it is necessary to focus not only on the level of the individual but also on the levels of family, health care setting, and society in general is necessary.

Background: Animal skin provides an ideal medium for the propagation of microorganisms and it is used like raw material in the tannery and footware industry. The aim of this study was to evaluate and identify the microbial load in oropharyngeal mucosa of tannery employees. Methods: The health risk was estimated based on the identification of microorganisms found in the oropharyngeal mucosa samples. The study was conducted in a tanners group and a control group. Samples were taken from oropharyngeal mucosa and inoculated on plates with selective medium. In the samples, bacteria were identified by 16S ribosomal DNA analysis and the yeasts through a presumptive method. In addition, the sensitivity of these microorganisms to antibiotics/antifungals was evaluated. Results: The identified bacteria belonged to the families Enterobacteriaceae, Pseudomonadaceae, Neisseriaceae, Alcaligenaceae, Moraxellaceae, and Xanthomonadaceae, of which some species are considered as pathogenic or opportunistic microorganisms; these bacteria were not present in the control group. Forty-two percent of bacteria identified in the tanners group are correlated with respiratory diseases. Yeasts were also identified, including the following species: Candida glabrata, Candida tropicalis, Candida albicans, and Candida krusei. Regarding the sensitivity test of bacteria identified in the tanners group, 90% showed sensitivity to piperacillin/tazobactam, 87% showed sensitivity to ticarcillin/clavulanic acid, 74% showed sensitivity to ampicillin/sulbactam, and 58% showed sensitivity to amoxicillin/clavulanic acid. Conclusion: Several of the bacteria and yeast identified in the oropharyngeal mucosa of tanners have been correlated with infections in humans and have already been reported as airborne microorganisms in this working environment, representing a health risk for workers.

The Canton Tower is a high-rise slender structure with a height of 610 m. A structural health monitoring system has been instrumented on the structure, by which data is continuously monitored. This paper presents an investigation on the identified modal properties of the Canton Tower using ambient vibration data collected during a whole day (24 hours). A recently developed Fast Bayesian FFT method is utilized for operational modal analysis on the basis of the measured acceleration data. The approach views modal identification as an inference problem where probability is used as a measure for the relative plausibility of outcomes given a model of the structure and measured data. Focusing on the first several modes, the modal properties of this supertall slender structure are identified on non-overlapping time windows during the whole day under normal wind speed. With the identified modal parameters and the associated posterior uncertainty, the distribution of the modal parameters in the future is predicted and assessed. By defining the modal root-mean-square value in terms of the power spectral density of modal force identified, the identified natural frequencies and damping ratios versus the vibration amplitude are investigated with the associated posterior uncertainty considered. Meanwhile, the correlations between modal parameters and temperature, modal parameters and wind speed are studied. For comparison purpose, the frequency domain decomposition (FDD) method is also utilized to identify the modal parameters. The identified results obtained by the Bayesian method, the FDD method and a finite element model are compared and discussed.

This paper proposes a modified tag collection algorithm that improves the drawback of the identified slot scan-based tag collection algorithm presented in a previous paper to improve the tag collection performance in active RFID systems. The previous identified slot scan-based tag collection algorithm is optimized in situations where all the tags store the fixed size of data, so it could not result in a good performance improvement with tags having the variable size of data. The improved tag collection algorithm proposed in this paper first collects the slot size information required for the data transmission from each tag via the identified slot scan phase, and then performs the tag collection phase using the information, which resolves the problem of the previous identified slot scan-based tag collection algorithm. The simulation results for performance evaluation showed that the proposed tag collection algorithm resulted in the almost same tag collection performance as the previous algorithm when all the tags have the same size of data and led a large improvement of the tag collection performance in ISO/IEC 18000-7 unlike the previous algorithm when each tag has a random size of data.
