3D printing bone models extracted from medical imaging data

Additive manufacturing in the form of 3D printing is becoming more common with the rise of low-cost hobby machines which makes research in the field of medicine more accessible. This article explores and experiments with methods of producing three dimensional replicas of body parts as education material from the medical imaging data of Computed Tomography and Magnetic Resonance Imaging.

Local EHR Management Based on openEHR and EN13606

This article describes handling medical data in a healthcare system based on electronic healthcare records. At a medical unit level, data storage requires both accurate collecting and high security. The proposed information model complies with EN 13606, which is a European health data communication standard approved by the European Committee for Standardization (CEN) and partly approved by the International Organization for Standardization (ISO).

Eye-Gaze Tracking Method Driven by Raspberry PI Applicable in Automotive Traffic Safety

This paper comes as a response to the fact that, lately, more and more accidents are caused by people who fall asleep at the wheel. Eye tracking is one of the most important aspects in driver assistance systems since human eyes hold much in-formation regarding the drivers state, like attention level, gaze and fatigue level. The number of times the subject blinks will be taken into account for identification of the subjects drowsiness. Also the direction of where the user is looking will be estimated according to the location of the users eye gaze. The developed algorithm was implemented on a Raspberry Pi board in order to create a portable system. The main determination of this project is to conceive an active eyetracking based system, which focuses on the drowsiness detection amongst fatigue related deficiencies in driving.

Medical information system based on electronic healthcare records

This article approaches the shortcomings of the current medical information systems and describes a solution compliant with the openEHR standard, used to structure and markup the clinical content. The paper puts forward a prototype for a medical software based on electronic healthcare records which meets the requirements of interoperability and high security of data. It ensures the accuracy and reliability of operations and the adaptability of the system to the continuous changes in the medical field. The application is applied to the particularities of the Romanian healthcare environment.

Electronic healthcare record according to general clinical observation file

Medical software systems in Romania lack the data interchange capability. By combining the force of knowledge in the computer science, information science and healthcare, this article provides a viable runtime solution for the electronic data management of the Romanian General Clinical Observation File in an efficient manner according with openEHR specifications. GCOF is composed of varied medical and demographical data and its content is regulating by the Ministry of Public Health.

Dietary patterns, physical activity, body mass index, weight-related behaviours and their interrelationship among Romanian university students-trends from 2003 to 2016

INTRODUCTION promotion of a healthy diet and involvement in physical activity among young people has an important impact on their actual and future lifestyle, health and well being. OBJECTIVES this study investigates dietary patterns, physical activity, body mass index (BMI) and weight-related behaviours as well as their interrelationship among Romanian university students. METHODS the study used anonymous questionnaires and was performed in Cluj-Napoca, Romania in 2003 (n = 320) and 2016 (n = 320). RESULTS the factor analyse revealed three main dietary structures which were similar at both waves. The first one describes a varied diet. The second one shows a diet rich in white meat, dietary fibres and varied sources of carbohydrates. The last one refers to a diet containing red meat, fat, potatoes, sugar. The first dietary structure protects against overweight and it correlates positively with daily physical activity, while has a negative correlation with using several methods for losing weight. The second dietary factor is also protective for overweight, but has a positive correlation with using several methods for losing weight. It has a negative association with eating frequently in fast food restaurants and with daily physical activity. The last dietary structure is negatively associated with daily physical activity, while being positively associated with eating frequently in fast-food restaurants and with a higher BMI. CONCLUSIONS the study presents trends in dietary patterns, physical activity, BMI and weight related behaviours among Romanian university students between 2003 and 2016 and highlights the existence of several main dietary structures, which seems stable over time.

Advanced control of a hydroelectric power plant

The paper presents an original method for controlling the real power delivered by a hydroelectric power plant to local electrical grid. The advanced control is based on: the implementation of the Internal Model Control strategy in order to obtain the system stabilization and robustness; the implementation of two feed-forward loops in order to reject more efficiently the effect of the disturbances; a control loop for the frequency correction. The main controller from the proposed control system has an original architecture and it is tuned using an original concept, too.

Elderly Fall Risk Prediction System

Preventing diseases of older persons and promoting the lack of necessity in consulting professionals is a priority in the Romanian health system as all these will lead to cost reduction in this important sector of the Romanian economy. Taking these in mind, we propose a new king of medicine, a medicine that is based on connectivity, collaboration, customization and computing. For this kind of medicine to work, we have developed an integrated system that will be used for compulsory planning and for compulsory regularly evaluation of the elder persons. Furthermore, where needed, telemonitoring and assistance will be used.

Developing the DESP system by improving the experimental model

The article reviews the experimental model developed within a Romanian research project and offers improvement suggestions that should be implemented in the upcoming prototype of the application. The investigation focused on security, user audit, interconnectivity and user interface.
