It is difficult to develop the financing and hospital provision of interventions for early rehabilitation within the diagnosis-related group (DRG) system. In addition to a range of partially rehabilitative complex interventions, the system recognizes three main forms of early rehabilitative interventions: geriatric, neurological/neurosurgical, and interdisciplinary and others. In this article, the appropriate definitions and cost-effectiveness of these procedures are analyzed and compared. The early rehabilitative interventions are characterized by constant cooperation in the therapeutic team, especially neurological early rehabilitation through the incorporation of nursing as a therapeutic profession. Whereas geriatric and neurological early rehabilitation are reflected in the DRG system, the former provided in many general hospitals and the latter mainly in specialized institutions, interdisciplinary early rehabilitation has only occasionally been represented in the DRG system so far. If all acute in-patients who require early rehabilitation should receive such an intervention, an additional fee must be implemented for this this interdisciplinary service. © 2017 Springer-Verlag Berlin Heidelberg

In this paper, we shortly review current challenges of distributed automotive software architectures with respectto economic considerations and discuss several principles ofthe Bitcoin crypto-currency in more depth. We then point out,how future architectures could benefit from those mechanisms and highlight that future research in this direction should beperformed, as we think that Bitcoin itself is not suited to enhance automotive software architectures. © 2016 IEEE.

The German Health Care System (GHCS) faces many challenges among which an aging population and economic problems are just a few. The GHCS traditionally emphasised equity, universal coverage, ready access, free choice, high numbers of providers and technological equipment; however, real competition among health-care providers and insurance companies is lacking. Mainly in response to demographic changes and economic challenges, health-care reforms have focused on cost containment and to a lesser degree also quality issues. In contrast, generational accounting, priorisation and rationing issues have thus far been completely neglected. The paper discusses three important areas of health care in Germany, namely the funding process, hospital management and ambulatory care, with a focus on cost control mechanisms and quality improving measures as the variables of interest. Health Information Technology (HIT) has been identified as an important quality improvement tool. Health Indicators have been introduced as possible instruments for the priorisation debate. © Georg Thieme Verlag KG Stuttgart · New York.

We recently addressed the challenges of the German Health Care System (GHCS) in an era of an aging population and economic problems discussing the funding process, hospital management and ambulatory care, with a focus on cost control mechanisms and quality improvement measures. Pharmaceutical issues have not been mentioned in detail. It is of interest that increases in Social Health Insurance (SHI) expenditures on pharmaceuticals in Germany were above the European average in the last decades. There are three main aspects to consider when it comes to discussing the topic of pharmaceuticals in health care services, the efficacy of the drugs, safety issues and cost containment. The paper summarizes pharmaceutical issues as challenges for the German Health Care System. © Georg Thieme Verlag KG Stuttgart · New York ·.

Purpose To present the beam properties of the Siemens 70-kV and 121-kV linear accelerator-mounted imaging modalities and commissioning of the 121-kV beam in the Philips Pinnacle treatment planning system (TPS); measurements in an Alderson phantom were performed for verification of the model and to estimate the cone-beam CT (CBCT) imaging dose in the head and neck, thorax, and pelvis. Methods and Materials The beam profiles and depth-dose curve were measured in an acrylic phantom using thermoluminescent dosimeters and a soft x-ray ionization chamber. Measurements were imported into the TPS, modeled, and verified by phantom measurements. Results Modeling of the profiles and the depth-dose curve can be achieved with good quality. Comparison with the measurements in the Alderson phantom is generally good; only very close to bony structures is the dose underestimated by the TPS. For a 200 arc CBCT of the head and neck, a maximum dose of 7 mGy is measured; the thorax and pelvis 360 CBCTs give doses of 4-10 mGy and 7-15 mGy, respectively. Conclusions Dosimetric characteristics of the Siemens kVision imaging modalities are presented and modeled in the Pinnacle TPS. Thermoluminescent dosimeter measurements in the Alderson phantom agree well with the calculated TPS dose, validating the model and providing an estimate of the imaging dose for different protocols. © 2014 Elsevier Inc.

This paper describes the motivation and work performed to establish ways to link between academia and industry in Jordan, in the field of mechatronics engineering. Two efforts are described. First, the creation of an on-line forum, called the Jordan Mechatronics Network (JMN), for mechatronics professionals inside and outside of Jordan to share knowledge and facilitate cooperation, considering that many Jordanian engineers find employment in Arab Gulf states. This forum operates in the English language, is open, free, and user driven. This setup helps sustain JMN over time with minimal cost and overhead. The second effort is placed into the establishment of a society for mechatronics engineers in Jordan under the umbrella of the Jordan Engineers Association (JEA). The ongoing work currently finalizes the rules and regulations of the society, which is named Jordan Mechatronics Engineers Society (JMES). The JEA was established in 1958 and currently has over 81000 members. The JEA and JMES follow a traditional rigorous setup in the Arabic language with regulations for elections, membership, funding, investment, social and political activities, etc. © 2012 IEEE.

The development of new species is a high priority for the diversification of the Chilean aquaculture sector. The yellowtail kingfish (Seriola lalandi) is a promising candidate for commercial production in recirculating aquaculture systems (RAS). This paper presents data on the culture of yellowtail kingfish in a marine RAS working for 488 days using artificial sea water. Growth performance, feed conversion, feeding rate, condition factor and mortality were determined for fish having an average initial weight (±S.D.) of 0.7 ± 0.2. g up to a final average weight of 2006. ±. 339.0. g. The RAS configuration (drum filter, protein skimmer with ozone, biological nitrification and denitrification, carbon dioxide removal and oxygenation) showed performance stability under the conditions assayed (low water renewal rate). Total ammonia nitrogen and nitrite-nitrogen concentration averaged 0.74. ±. 0.42. mg/L and 0.21. ±. 0.24. mg/L respectively. After installation, the denitrification reactor kept nitrate-nitrogen concentrations below 40. mg/L. Nitrate-nitrogen was totally reduced at oxidation reduction potential values between -150 and -250. mV. Water temperature averaged 22.6. ±. 1.4. °C and oxygen was maintained close to saturation levels. Carbon dioxide concentration was in average 8.3. ±. 2.47. mg/L and pH 7.5. ±. 0.1. Water renewal rate was 0.45% of the total system volume per day. The system proved the capability to maintain optimal water quality and secured animal welfare. © 2013 Elsevier B.V.


Purpose: What is therapeutic nursing? This question is gaining relevance in the context of the billing of services in the DRG system (DRG=Diagnosis-Related Groups), because in paragraph 8-552 of the operations and procedures coding system (OPS), it is explicitly stated that therapeutic care must be carried out by specially trained personnel. To date, empirical results on therapeutic nursing in neurological early rehabilitation are sparse. The objective of the study is to develop a theory of therapeutic care in neurological early rehabilitation. Materials and Methods: The study is based on the method of grounded theory. Open participatory observations (n=92) and episodic interviews (n=10) with nursing professionals and nursing auxiliaries were conducted in 5 inpatient rehabilitation clinics. Results: The theory of therapeutic nursing includes 6 categories: (1) nursing care, (2) observation/perception, (3) communication, (4) autonomy and individual needs of patients and their relatives, (5) multi-professional team and (6) prerequisites. Discussion: The results indicate which aspects are included in therapeutic nursing and the necessary prerequisites for delivering therapeutic nursing. Against this background, continuing education programs reveal conspicuous gaps in the area of knowledge transfer and application in practice. Conclusions: The results of the study should be taken into consideration and integrated in nursing education, both at the basic level and in continuing education.

In architecture, shell construction is used for the most efficient, large spatial structures. Until now the use of wood rather played a marginal role, implementing those examples of architecture, although this material offers manifold advantages, especially against the background of accelerating shortage of resources and increasing requirements concerning the energy balance. Regarding the implementation of shells, nature offers a wide range of suggestions. The focus of the examinations is on the shells of marine plankton, especially of diatoms, whose richness in species promises the discovery of entirely new construction principles. The project is targeting at transferring advantageous features of these organisms on industrial produced, modular wood shell structures. Currently a transfer of these structures in CAD - models is taking place, helping to perform stress analysis by computational methods. Micro as well as macro structures are the subject of diverse consideration, allowing to draw the necessary conclusions for an architectural design. The insights of these tests are the basis for the development of physical models on different scales, which are used to verify the different approaches. Another important aim which is promoted in the project is to enhance the competitiveness of timber construction. Downsizing of the prefabricated structural elements leads to considerable lower transportation costs as abnormal loads can be avoided as far as possible and means of transportation can be loaded with higher efficiency so that an important contribution to the sustainability in the field of architecture can also be made. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
