Aims and Objectives:
Preventive home visits are a low-threshold counselling and support approach. They have been reported to achieve heterogeneous effects. However, preventive home visits have the potential to reduce the risk of becoming dependent on long-term care. The aim of this study is to investigate the effect of preventive home visits as a nursing intervention on health-related quality of life of older people in a longitudinal survey and to develop recommendations for which target groups preventive home visits have the highest benefit. The sample consisted of 75 people, aged between 65 and 85, who were able to understand and speak German, had not yet been eligible for benefits from the long-term care insurance and lived in the municipality under study.
Methodological Design and Justification:
A quantitative longitudinal study in order to investigate the effects of preventive home visits.
Ethical Issues and Approval:
There were no ethical concerns. Accordingly, ethical approval was granted.
Research Methods, Results and Conclusions:
The health-related quality of life was recorded four times between 01/2017 and 08/2020 with the Short-Form- Health- Survey- 12 and analysed using descriptive statistics. Results reveal that the physical health status cannot be easily influenced over a short period of time. The main effect, however, is that preventive home visits have a significant positive effect on the mental health status. The main topics during the home visits were mobility, nutrition and social participation. Increased knowledge and motivation for preventive behaviour extended the autonomy of older people. Accordingly, preventive home visits can support a self-determined life in a familiar environment. The results of the present study show that preventive home visits as a nursing intervention in rural areas are successful. In Germany, preventive home visits have not yet been implemented on a regular basis. In order to do so, a general definition of the concept is needed. Preventive home visits should be officially included in the regular health care services in Germany.
A systematic study was performed to understand the effects of the devulcanizing agent dibenzamido diphenyl disulfide (DBD) on the vulcanization and devulcanization process of a sulfur-cured ethylene-propylene-diene monomer (EPDM) rubber. The influence of DBD on vulcanization was investigated by mixing DBD with virgin rubber and curative system. The devulcanization of rubber waste was achieved with varying amounts of DBD ranging from 0.4 to 13.8 wt% and temperatures from 150 to 200°C. The quality of vulcanizates and devulcanizates was evaluated by rheometer tests, temperature scanning stress relaxation measurements, and analysis of mechanical properties. During vulcanization, DBD acts as an accelerator in the presence of sulfur. When accelerators are added, the scorch time increases, and the cure rate decreases. Thus, DBD acts as a retarder. In the presence of activators, DBD leads to a significant reduction of crosslink density. This results in composites with high elongation at break and poor compression set values. The efficiency of the devulcanization of rubber waste depends strongly on DBD concentration and temperature. The monosulfidic crosslinks are cleaved by low concentrations of DBD, while polysulfidic crosslinks require higher concentrations. These results show that DBD is effective as a devulcanizing agent and degrades the network below 200°C.
Hintergrund: Die Digitalisierung durchdringt mittlerweile alle Bereiche unseres Lebens und zunehmend auch das Handlungsfeld der Pflege. Mithilfe medial gestützter Lehrgestaltung können Lernende auf digitale Herausforderungen ihres Berufsalltags vorbereitet werden. Zudem müssen Pflegende über ein individuell und fallbezogen anwendbares Fachwissen verfügen, welches mittels des Konzeptes der hermeneutischen Fallarbeit vermittelt wird. Virtuelle Simulationen können authentische Fallszenarien darstellen und das konventionelle Konzept der Fallarbeit mit moderner Technik erweitern.
Ziel: Ziel der Recherche ist, national und international verwendete Arten digitaler und virtueller Medien in Verbindung mit der Methode der hermeneutischen Fallarbeit im Kontext der Gesundheitsbildung zu identifizieren und dessen Nutzen zu beschreiben.
Methoden: Es ist eine Literaturrecherche im Design eines systematischen Reviews in den Datenbanken CINAHL, MEDLINE via PubMed, Cochrane und Springer Link durchgeführt und mit dem Schneeballprinzip ergänzt worden.
Ergebnisse: Es wurden elf Publikationen eingeschlossen. Die Ergebnisse zeigen überwiegend positive Auswirkungen, die sich in elf Kategorien unterteilen lassen. Schlussfolgerung: Der Einsatz von virtuellen Patient_innen wird auch in der empirischen und mediendidaktischen
Forschung als ein effektives und effizientes Lernarrangement angesehen. Sowohl im positiven wie auch negativen Sinne, sind die Ergebnisse abhängig von der didaktisch-methodischen Aufarbeitung, dem Design der Lernmodule und der Qualität des Mediums wie auch der Lehre.
The energy transition can be mapped on four levels. While industry and the state should act on the national and international level, most of the energy transition is taking place at the regional and municipal levels. Here the small-scale and decentralized nature of the new energy world is reflected, where customized individual solutions are created.
The current study presents a new class of functional derivatives (1–3) consisting of a dicationic viologen (4,4’-bipyridinium unit) (V21) capped by nucleobases thymine (NB1), adenine (NB2), thymine/adenine (NB1, NB2), and ion-paired with amphiphilic anion 3,4,5-tris(dodecyloxy)benzene sulfonate (DOBS-). The target of our work focuses on the design and synthesis of molecular building blocks in which three different functionalities are combined: chromophore (V21 unit), molecular recognition (NB unit), and thermotropic liquid crystal (DOBS unit). The resulted materials exhibit liquid crystalline properties at ambient temperature with significant particularities-induced by nucleobases in the mesogen structure. Structure–properties relationship study focuses on providing knowledge about (1) how the thermotropic, redox properties, thermochromism, or ionic conductive properties are influenced by the presence of purinic or pyrimidinic nucleobases, and (2) how effective is their ability to selfassembly by hydrogen bonding in nonpolar solvents. The presence of nucleobases has been proved to have a substantial impact on electron transfer rate during the reduction of viologen moieties by intermolecular aggregation. Ionic conductivity and thermochromic properties of derivatives 1–3 were investigated and compared to a non-containing nucleobase analog methyl viologen with 3,4,5 tris(dodecyloxy)benzene sulfonate anion (MV) as reference.
Die Digitalisierung hat in den letzten Jahren für Privatpersonen und Unternehmen zunehmend an Bedeutung gewonnen und die Art des gesellschaftlichen Zusammenlebens erheblich verändert. Das gilt natürlich auch für die Arbeit in Steuerkanzleien. In welchen Punkten dort veränderte oder neue Anforderungen an Mitarbeitende und ihre Kompetenzen feststellbar sind und inwiefern darauf auch schon bei der Ausbildung im dualen Studium reagiert werden kann, zeigt dieser Beitrag auf, der das Studium der Wirtschaftsinformatik mit Steuermodulen vorstellt.
