The number of medical malpractice lawsuits filed each year in Hungary has considerably increased since 1990. The judicial decisions and practices on determining and awarding wrongful damages recoverable for medical malpractices in the Hungarian civil law have been developing for decades. In the meantime, a new Hungarian Civil Code (Act V of 2013) has entered into force, which among others, necessitates the revaluation of assessment of damages recoverable for medical malpractices. There are two main areas where fundamental changes have been introduced, which may significantly affect the outcome of medical malpractice lawsuits in the future. In the early stage of medical malpractices it was unclear whether the courts had to consider either the contractual relationship between patients and healthcare providers (contractual liability) or general codal articles on damages arising from non-contractual liability/torts (delictual liability) in their judgement delivered in the cases. Both the theoretical and practical experience of the last ten years shows that healthcare services agreements are concluded between healthcare providers and patients with the aim and intention to provide appropriate professional healthcare services to patients, which meet patients’ interests and wishes. The medical service is violated if it fails to meet patients’ interests and wishes as well as the objectives of the agreement. Since the new legislation implies a stricter liability for damages in the case of breach of contract and stricter rules for exempting the party in breach from compensation obligations, the opportunities to exempt healthcare providers from these obligations have become limited compared to previous regulations. This modification, which was aimed at further integrating the established judicial practices into legislation, stipulates the application of the rules for liability for damages resulting from medical malpractice in non-contractual situations. This paper analyses dogmatic and practical problems related to this topic. Another important area of current analysis is the institution of injury fees, which replaced the reimbursement of non-pecuniary damages. The mere fact of infringement allows setting injury fees. Taking into consideration the current resources in staff and equipment available in healthcare, this regulation may promote claims for injury fees impartial. Consequently, courts will have to apply other criteria when judgment in ‘trivial cases’, which might not require legal assessment, is delivered. Orv. Hetil., 2014, 155(38), 1510–1516.

This paper analyses the issue of convergence in the Eurozone. The overarching objective was to evaluate the monetary and fiscal convergence of the countries in the Eurozone during the recent period. A further goal was to establish recommendations boosting the economic efficiency of the analysed currency integration of the Eurozone. The paper pinpoints crucial theoretical underpinnings and the current analysis of the Eurozone. Empirical data pertinent to macroeconomic indicators, which were collated and statistically analysed, were also used to delineate crucial issues of convergence in the Eurozone.

Introduction:This paper focuses on improving the power amplifier linearity for wireless communications. The use of a single branch of a power amplifier can produce high distortion with low efficiency.Method:In this paper, the Linear Amplification with Nonlinear Components (LINC) technique is used to improve the linearity and efficiency of the power amplifier. The LINC technique is based on converting the envelope modulation signal into two constant envelope phase-modulated baseband signals. After amplification and combining the resulting signals, the required linear output signal is obtained. To validate the proposed approach, LINC technique is used for linearizing an amplifier based on a GaAs MESFET (described by an artificial neural network Model).Conclusion:Good results have been achieved, and an improvement of about 40.80 dBc and 47.50 dBc respectively is obtained for the Δlower C/I and Δupper C/I at 5.25 GHz.
