ANALYSIS AND PROSPECTS OF DEVELOPMENT OF WINE EXPORT FROM PREFECTURE OF DRAMA

One of the reasons of the crisis we are experiencing today is the dramatic reduction of the primary sector. However, in regions such as the prefecture of Drama, there is the possibility of developing and strengthening of the primary sector in the wine domain. This study presents the development of wine industry and its recent export activity. More specifically, it analyses the wine domain existing situation in the prefecture of Drama and the export activity from 2009 to 2015. There is a trend going around favoring extroversion in the Greek winemaking industry after the advent of the economic crisis in Greece in 2009. It also analyses the wine sector’s existing situation in global, national and regional level, especially in the prefecture of Drama. The survey highlights useful conclusions concerning the production, the consumption, the stocks, the imports and exports of wine and the obstacles encountered in the export activity. Moreover, the dynamics of Drama\u27 s winery and activity, including wine exports for the six years 2009-2015 both to the EU countries and with the third countries after the collection of secondary data, are presented and analyzed. Finally, it presents the export activity of prefecture of Drama in comparison to domestic/national export activity is also analyzed for the same period of time. Although the survey was conducted in a particular region, it draws useful conclusions which can be exploited for generalization in future work

Consuming foods and household products in Greece : a statistical analysis

The total income of the Greek households has been decreased in the last years. So, purchases are bravely decreased. In this paper, we study the consuming of household products and basic foods by the Greek households. We wish to study if consuming behaviour of Greek households has been changed after the crisis; if the consumers check the prices of the products more carefully; if they prefer more economic labels, etc. For this purpose, an empirical analysis with a questionnaire has been conducted in February 2014 in Greece. We present and analyze the responses of this questionnaire, using descriptive statistics and Data Analysis methods.peer-reviewe

Healthcare resources consumed by foreign patients in the public hospitals of East Macedonia and Thrace

The rising healthcare expenditures as percentage of GDP is a reality that all developed countries have to deal with. Epidemiologic standards have changed dramatically since the past. The rapid development of knowledge in the scientific field of medicine and the new state of the art medical technology has led to new treatments for various health problems. Prior fatal diseases have become chronic, and life expectancy has risen significantly, leading healthcare costs to explosion. Healthcare spending in Greece has been increased between 2000 and 2009 at a rapid rate of 6.1% per year, but it has dropped the following years, driven by a sharp reduction in public spending on health care as part of government-wide efforts to reduce the large budgetary deficit. This situation has caused an increasing offence sense in population. On the other hand, the last years, Greece has become an immigrant (legal and illegal) reception centre. This study presents comparative data about the consumed resources by Greek and foreign patients in the public hospitals of east Macedonia and Thrace for the years 2006-2010.peer-reviewe

Evaluation of operational programme “competitiveness” in the frames of the 3rd Community Support Framework (CSF) : action 2.11.2

This study is aiming to outline the entrepreneurs’ opinions regarding to the effect of the Intermediary Management Agencies (IMAs) and the subsidy Operational Programmes (OPs) in the concretisation of their investments. More specific, the study aims into the acquisition of knowledge and information about important subjects of the Operational Programme “Competitiveness” - Action 2.11.2 that concern the modernisation and development of enterprises that belong to the Tertiary Sector of the Central Macedonia Region, such as: Programme’s contribution in the development of enterprises and the Greek economy, the entrepreneurs’ opinion about the Intermediary Management Agencies in the process of their investments’ completion and finally, the exploration of other interesting elements that had significantly contributed in the investments’ completion. This research constitutes a first effort to evaluate Operational Programmes of the 3rd Community Support Framework (CSF) that its results will be published, in opposition of the forecasted ex-ante or ex-post evaluations that are produced in the frames of each Intermediary Management Agency’s obligations on behalf of the empowered National and Community Committee. In other words, the results of this research will contribute in the activation of an essential dialogue and most important will contribute in the pursued more effective exploitation of the available resources. Taking into consideration the occasional reports of the empowered Community Authorities about Greek Intermediary Management Agencies’ weaknesses, among other countries, in the field of rational management and exploitation of the Community resources, we mainly consider particularly useful and topical the discoveries of this research facing the imminent launch of the 4th CSF Operational Programmes.peer-reviewe

FINALLY, WE SUGGEST AN EASY AND UNIQUE WAY FOR THE CORRESPONDENCE OF A NEW VARIABLE TO THE OBJECTS OF EACH CLASS, USING THE RESULTS OF A CLASSIFICATION DENDROGRAM

What Accuracy for 3D Measurements with Cameras?

International audienceWe estimate the internal and external parameters of the camera, and simultaneously the distortion's parameters. Our aim is the selection of the best distortion model, using statistical test for the importance of distortion parameters. Also we examine the accuracy in camera parameter estimation and 3D reconstruction, in relation with the noise in the image. We answer the question 'until which level of noise, is it possible to obtain a good camera parameter estimation, and from there a good reconstruction?'. Experiments are evaluated on simulated data and a rest is performed with real data

Manufacturing strategies and financial performance--The effect of advanced information technology: CAD/CAM systems

Nowadays, the business environment is characterized by great uncertainty and variability. In this environment, information technology (IT) has proved to be an important strategic ingredient for the creation of competitive advantage. This role of IT has been widely accepted during the past few years [Feeny D. Creating and sustaining competitive advantage with IT. In: Earl M, editor. Information management the strategic direction. Oxford, 1990; Ives B. Wingtip Courriers, Southern Methodist University Case Study #SMY/MIS/90-01, Edwin L. Cox School of Business, Dallas, TX, January 1990]. In the new era of production, strategic priorities rather than a cost contained focus have proved to be important for competition, namely: quality, dependability, flexibility, customer service, after sale service, supply chain management, etc. IT proved to be vital for successful competition as it can facilitate the attainment of these strategic targets. In this paper, the impact of IT on financial performance for the different types and levels of business strategy is examined. After the clustering of firms according to their strategic priorities, the effect of IT on financial performance is estimated. To do this a cross-sectional study was held in the field of Greek manufacturing firms that apply advanced IT, in order to explore which, how and in what level manufacturing priorities have been adopted. For that purpose, cluster analysis and VACOR algorithm were used, to distinguish clusters of firms and estimate the effect of IT on financial performance, for each type and level of strategic choice. Return on invested capital (ROIC) has been used as a criterion of performance in order to incorporate the effect of cost, revenues and profits. It was found that the effect of IT on financial performance was observed to be greater for firms which emphasize the higher level of flexibility strategy and the middle level of cost strategy. On the contrary, the effect of IT on performance was observed to be greater for firms which emphasize a lower level of quality and innovation strategy. Further discussion of these results and conclusions were drawn.Information systems MIS Flexible manufacturing Statistics Cost benefit analysis
