The Implementation of Innovative Services in Education by Using Cloud Infrastructure and Their Economic Aspects
Global Journal of Flexible Systems Management, 2014Co-Authors: Peter Balco, Michal GregušAbstract:Today’s economic environment including commercial as well as non-commercial environments requires from suppliers cost effective services. The debates regarding this topic are presenting different strategies. In the first group are supporters of traditional technology including Internal solutions with low level of flexibility. On the other hand we have groups of professionals who understand very well the market requirements. These non-standard innovative solutions provide a high level of autonomy for users, flexibility in management and open space for creativity in the future. Our paper provides information related to economic aspects of implementation of the services based on cloud concept. In our case the process of education was adapted in cloud environment to reduce investment and operation cost of organization responsible for education of Internal Staff.

outcomes of transfemoral transcatheter aortic valve implantation at hospitals with and without on site cardiac surgery department insights from the prospective german aortic valve replacement quality assurance registry aqua in 17 919 patients
European Heart Journal, 2016Co-Authors: Holger Eggebrecht, Maike Bestehorn, Michael Haude, Axel Schmermund, Kurt Bestehorn, Thomas Voigtlander, Karlheinz Kuck, Rajendra H MehtaAbstract:Aims Performing transcatheter aortic valve implantation (TAVI) at hospitals with only cardiology department but no cardiac surgery (CS) on-site is at great odds with current Guidelines. Methods and results We analysed data from the official, prospective German Quality Assurance Registry on Aortic Valve Replacement to compare characteristics and in-hospital outcomes of patients undergoing transfemoral TAVI at hospitals with ( n = 75) and without CS departments ( n = 22). An interdisciplinary Heart Team was established at all centres (Internal Staff physicians at hospitals with on-site CS; in-house cardiologists and visiting cardiac surgical teams from collaborating hospitals at non-CS hospitals). In 2013 and 2014, 17 919 patients (81.2 ± 6.1 years, 55% females, German aortic valve (GAV) score 2.0 5.6 ± 5.8%, logistic EuroSCORE I 21.1 ± 15.4%) underwent transfemoral TAVI in Germany: 1332 (7.4%) at hospitals without on-site CS department. Patients in non-CS hospitals were older (82.1 ± 5.8 vs. 81.1 ± 6.1 years, P < 0.001), with more frequent co-morbidities. Predicted mortality risks per GAV-score 2.0 (6.1 + 5.5 vs. 5.5 ± 5.9%, P < 0.001) and logEuroSCORE I (23.2 ± 15.8 vs. 21.0 ± 15.4%, P < 0.001) were higher in patients at non-CS sites. Complications, including strokes (2.6 vs. 2.3%, P = 0.452) and in-hospital mortality (3.8 vs. 4.2%, P = 0.396), were similar in both groups. Matched-pair analysis of 555 patients in each group with identical GAV-score confirmed similar rates of intraprocedural complications (9.2 vs. 10.3%, P = 0.543), strokes (3.2% for both groups, P = 1.00), and in-hospital mortality (1.8 vs. 2.9%, P = 0.234). Conclusion Although patients undergoing TAVI at hospitals without on-site CS department were older and at higher predicted perioperative death risk, major complications, and in-hospital mortality were not statistically different, suggesting the feasibility and safety of Heart Team-based TAVI at non-CS sites. These findings need confirmation in future randomized study.

prediction of financial distress an empirical study of listed chinese companies using data mining
European Journal of Operational Research, 2015Co-Authors: Ruibin Geng, Indranil Bose, Xi ChenAbstract:The deterioration in profitability of listed companies not only threatens the interests of the enterprise and Internal Staff, but also makes investors face significant financial loss. It is important to establish an effective early warning system for prediction of financial crisis for better corporate governance. This paper studies the phenomenon of financial distress for 107 Chinese companies that received the label ‘special treatment’ from 2001 to 2008 by the Shanghai Stock Exchange and the Shenzhen Stock Exchange. We use data mining techniques to build financial distress warning models based on 31 financial indicators and three different time windows by comparing these 107 firms to a control group of firms. We observe that the performance of neural networks is more accurate than other classifiers, such as decision trees and support vector machines, as well as an ensemble of multiple classifiers combined using majority voting. An important contribution of the paper is to discover that financial indicators, such as net profit margin of total assets, return on total assets, earnings per share, and cash flow per share, play an important role in prediction of deterioration in profitability. This paper provides a suitable method for prediction of financial distress for listed companies in China.

fmea methodology design implementation and integration with haccp system in a food company
Food Control, 2002Co-Authors: Antonio Scipioni, Giovanni Saccarola, Angela Centazzo, Francesco ArenaAbstract:Abstract This paper reports the description of FMEA methodology design and implementation in a food company, where, integrated with HACCP system, it is used as a tool to assure products quality, and as a mean to improve operational performance of the production cycle. The work was developed in an Italian confectionery industry, Elledi SpA, in co-operation with part of the Internal Staff, chosen as FMEA team members, and was focused on the study of wafer biscuit production lines. All the work done permits to increase company knowledge and control capacity on processes and products. The generated data can be used as a useful technical database for future update of FMEA in Elledi and as a model of FMEA design for similar company.
