Romanian Health Care Reform in the Context of Economic Crisis
Victoria Gheonea,Nicoleta Constandache,Gianina Roman
Acta Universitatis Danubius : Oeconomica , 2010,
Abstract: The effects of financial crisis are strongly felt in Romania, which already face with asignificant slowdown in economic growth or even economic recession. The current and internationalsituation remains still difficult, and requires high budget constraints. Under these conditions, thehealth system in Romania has become one of the most inefficient in Europe, mainly characterized bylack of transparency in the allocation of funds and inefficiency in resource use. The lack of clear andcoherent criteria to evaluate the performance of health institutions results in a difficultimplementation of efficient managerial systems to reward the efficient manager.
Diagnosis Related Groups System - Managerial Tool for Estimating the Cost of Hospital Services (Empirical Study)
Carmen-Mihaela Cre?u,Victoria Gheonea
EIRP Proceedings , 2012,
Abstract: Public health services in Romania are in a complex and continuous process of reform, a majorpriority of government. In the light of future trends of development of health care, we can say that healthcareis becoming more and more a "market" operating on the principle of supply and demand. The patientbecomes a consumer; he is interested in health care and wants to be adept at maintaining and improving hishealth. Therefore, the Romanian health sector must intensify efforts to develop management because successand even its existence depend exclusively on an appropriate management system that continuously improvesto the needs of the patient (customer) and to the market economy. Thus, we considered it necessary forcosting approach in the health sector in Romania due to the high complexity of health services and the highconsumption of resources.
Comparative Study on Presentation of Statement of Financial Position in the Public Sector
Carmen Cre?u,Victoria Gheonea,Carmen S?rbu
Acta Universitatis Danubius : Oeconomica , 2011,
Abstract: Although it is more than a decade since the elaboration of the first public accountingstandards, countries are still reluctant to adopt them, preferring rather an adaptation of nationallegislation with the provisions IPSASs. Concerns about the necessity and usefulness of the applicationof International Public Sector Accounting Standards are due to economic influences, cultural, social,which made their mark on philosophy, doctrine and national accounting policies. Although financialstatements may appear similar from country to country, there are differences that can be caused by avariety of social, economic and legal factors, and that some countries when setting the nationalrequirements have considered the needs of different users of financial statements. These factors haveled to the use of different definitions of the structures of financial statements, such as assets,liabilities, equity, revenues and expenses. Scope and disclosures in the financial statements were alsoaffected. Therefore, this paper intends to emphasize similarities, but especially the differencesbetween the two frames of reference - national norms to international standards - regarding Statementof financial position on a public institution.
Examination of Three Case Studies of Caring for Psychiatric Patients on a Medical Surgical Unit  [PDF]
Victoria Siegel
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.413096
Abstract:
Medical surgical nurses frequently care for patients with psychiatric disorders as one in four people have a diagnosed psychiatric disorder. Since these nurses specialize in medical surgical nursing, they often feel they lack the expertise to care for patients with co-morbid psychiatric problems. This article presents three case studies and delineates nursing care strategies which could assist the medical-surgical nurses in caring for this population.

World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i32.4427
Abstract: AIM: To study the role of time-intensity curve (TIC) analysis parameters in a complex system of neural networks designed to classify liver tumors. METHODS: We prospectively included 112 patients with hepatocellular carcinoma (HCC) (n = 41), hypervascular (n = 20) and hypovascular (n = 12) liver metastases, hepatic hemangiomas (n = 16) or focal fatty changes (n = 23) who underwent contrast-enhanced ultrasonography in the Research Center of Gastroenterology and Hepatology, Craiova, Romania. We recorded full length movies of all contrast uptake phases and post-processed them offline by selecting two areas of interest (one for the tumor and one for the healthy surrounding parenchyma) and consecutive TIC analysis. The difference in maximum intensities, the time to reaching them and the aspect of the late/portal phase, as quantified by the neural network and a ratio between median intensities of the central and peripheral areas were analyzed by a feed forward back propagation multi-layer neural network which was trained to classify data into five distinct classes, corresponding to each type of liver lesion. RESULTS: The neural network had 94.45% training accuracy (95% CI: 89.31%-97.21%) and 87.12% testing accuracy (95% CI: 86.83%-93.17%). The automatic classification process registered 93.2% sensitivity, 89.7% specificity, 94.42% positive predictive value and 87.57% negative predictive value. The artificial neural networks (ANN) incorrectly classified as hemangyomas three HCC cases and two hypervascular metastases, while in turn misclassifying four liver hemangyomas as HCC (one case) and hypervascular metastases (three cases). Comparatively, human interpretation of TICs showed 94.1% sensitivity, 90.7% specificity, 95.11% positive predictive value and 88.89% negative predictive value. The accuracy and specificity of the ANN diagnosis system was similar to that of human interpretation of the TICs (P = 0.225 and P = 0.451, respectively). Hepatocellular carcinoma cases showed contrast uptake during the arterial phase followed by wash-out in the portal and first seconds of the late phases. For the hypovascular metastases did not show significant contrast uptake during the arterial phase, which resulted in negative differences between the maximum intensities. We registered wash-out in the late phase for most of the hypervascular metastases. Liver hemangiomas had contrast uptake in the arterial phase without agent wash-out in the portal-late phases. The focal fatty changes did not show any differences from surrounding liver parenchyma, resulting in similar TIC patte
Endoscopic Ultrasound Elastography in the Diagnosis of Pancreatic Cancer
A. Saftoiu,P. Vilmann,F. Gorunescu,D.-I. Gheonea
Annals of Gastroenterology , 2010,
Abstract: Palpation continues to be of great value in modern medicine, both practiced by doctors and as a technique for selfexamination. But, palpation is limited to a few accessible organs, and the interpretation of the information sensed by the fingers is highly subjective. Recently, elastography has emerged as an option in several commercial ultrasound systems, and is starting to prove clinically valuable in many areas, particularly for example in assisting breast cancer diagnosis, 1 in guiding minimally invasive treatment of prostate cancer,2 or assessing liver fibrosis in diffuse hepatopathies by the transabdominal approach.
The Body Mass Index (BMI) and TV Viewing in a Co-Integration Framework  [PDF]
Anastasia Victoria Lazaridi
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.23037
Abstract: Many techniques are met in the literature, trying to investigate the effect of TV watching hours on BMI. However, we haven’t traced any empirical study with co-integration analysis, as it is applied here. With this in mind, we present in this paper the proper methodology, based on the co-integration analysis for a detailed justification of the effect of TV viewing hours together with some minor changes in life style of participants on BMI. Apart from finding and testing an acceptable co-integration relation, we further formulated an error correction model to determine the coefficient of adjustment. All findings, which are fully justified, are presented in details in the relevant sections. It should be pointed out, that we haven’t met this type of analysis in the relevant literature.
Technology Policy Implementation Road: Exploring Firms’ Technology Readiness in a Mandatory Vertical Diffusion Environment  [PDF]
Victoria E. Erosa
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.65A003
Abstract:

Technology Transfer and Technology Diffusion body of knowledge emerge from the research interest to explore the demand side of technology transfer by identifying the firm’s technology readiness to operate a new technology—product and process—in the context of the transfer of technology from a single source to multiple receivers/users—termed vertical diffusion—, where the adoption is by mandate. Demarcating the e-Invoice document as technology transfer object, this paper presents results of quantitative study performed with data collected from a 137 small retail firms, oriented to identify their technology readiness in terms of technology infrastructure and skills to operate under the electronic invoice legal procedure, as well as their perceived barriers for the diffusion. Results of factor analysis reveal insufficient information among all the participant firms, reflecting poor communication from the technology source, low awareness for the software solution available and of the competences/skills required to operate it as well as a passive attitude from the adopter who leans in a third party option to face the mandate.

Investigating Road Safety Management Systems in the European Countries: Patterns and Particularities  [PDF]
Victoria Gitelman, Etti Doveh
Journal of Transportation Technologies (JTTs) , 2016, DOI: 10.4236/jtts.2016.65032
Abstract: A road safety management (RSM) system can be defined as “a complex institutional structure that involves cooperating and interacting bodies which support the tasks and processes necessary for the prevention and reduction of road traffic injuries”. RSM should promote the road safety progress of the country. However, the details of this relationship are generally lacking. This study explored the RSM systems in European countries based on the information collected through interviews with experts and officials, in each country, and using a “good practice” criteria questionnaire. The dataset included 14 countries with fifty items related to five RSM areas: institutional organization; policy formulation and adoption; policy implementation and funding; monitoring and evaluation; scientific support, information and capacity building. Cluster analyses and correlations were used to identify country groups with similar RSM components, to recognize typical RSM structures if available and to examine the relationship between RSM and road safety performance of the countries. The findings showed that all the countries are different when RSM systems are considered as a whole, making it impossible to identify typical RSM structures or a single best working model at a national level. However, it is possible to compare countries when the RSM areas are considered separately, where the clusters of countries recognized by the study present the patterns common for those European countries. Across the analyses, a number of countries with a consistently higher and lower availability of the RSM components were identified, enabling a final countries’ ranking into a number of groups. The latter actually reflects the level of RSM in the country, in terms of its correspondence to the “good practice” criteria. A further analysis indicated a positive correlation between the higher level of the RSM system and better safety performance of the countries.
