Conditional-based maintenance (CBM) decision-making is of high interests in recent years due to its better performance on cost efficiency compared to other traditional policies. One of the most respected methods based on condition-monitoring data for maintenance decision-making is Proportional Hazards Model (PHM). It utilizes condition-monitoring data as covariates and identifies their effects on the lifetime of a component. Conventional modeling process of PHM only treats the degradation process as a whole lifecycle. In this paper, the PHM is advanced to describe a multi-zone degradation system considering the fact that the lifecycle of a machine can be divided into several different degradation stages. The methods to estimate reliability and performance prognostics are developed based on the proposed multi-zone PHM to predict the remaining time that the machine stays at the current stage before transferring into the next stage and the remaining useful life (RUL). The results illustrate that the multi-zone PHM effectively monitors the equipment status change and leads to a more accurate RUL prediction compared with traditional PHM.

Background and context: Lung cancer is estimated to be the fifth most commonly diagnosed cancer and leading cause of cancer death in Australia, representing 9.2% of all new cancer cases (n = 138,321) diagnosed and 18.9% of all cancer deaths (n = 48,586). The 5-year survival rate for those with lung cancer is 16%, compared with 68% for all cancers combined (between 2009 and 2013). Lung cancer is also the leading cause of cancer burden in Australia and patients affected by lung cancer may experience high levels of unmet need with associated psychological distress and decreased quality of life. Cancer Australia, Australia's national cancer control agency, developed the national Lung Cancer Framework: Principles for Best Practice Lung Cancer Care (Framework) to provide evidence-based, best practice information, strategies, tools and resources to support local adoption of the 5 principles for best practice management of lung cancer (principles): patient-centered care; multidisciplinary care; timely access to evidence-based care; coordination, communication and continuity of care; and data-driven improvements. Aim: The framework aims to improve the outcomes and experiences of people affected by lung cancer in Australia by supporting national uptake of the principles. Strategy/Tactics: Cancer Australia: • established a Lung Cancer Advisory Group to advise on strategies for national implementation of the framework and its principles • conducted a national lung cancer demonstration project, with advice from an Expert Steering Group, to demonstrate the delivery of lung cancer care according to the principles across a range of service delivery settings, and identify key factors contributing to ongoing delivery of best practice cancer care • completed systematic reviews for each principle to determine the effectiveness of the principles in improving lung cancer care processes and outcomes. Program/Policy process: To support national adoption of the framework and its principles, Cancer Australia: • developed a promotion and communication strategy for widespread national dissemination • convened a National Summit to bring together policy makers, clinical stakeholders and consumers to support local application of the principles, and drive optimal care for people affected by lung cancer • identified and communicated consumer, service, and system-level approaches to aid sustainable use of the principles. Outcomes: The evidence-based approach to the development of the framework and its principles identified ways to improve the healthcare system to achieve better outcomes for those affected by lung cancer in Australia. A coordinated approach to the delivery of the National Summit supported those involved in lung cancer care to share and adopt innovative and multilevel strategies for best practice care. What was learned: Embedding strategies to support implementation of the principles, responsive to local context, was key to enabling sustainable improvements in national lung cancer control.

The input parameters are very crucial in simulation tools for the analysis of data after the implementation. Authors in Mobile ad hoc Networks and particularly in Internet gateway discovery, face some challenges on how to decide on the choice of specific parameters. A wrong choice of input parameters could lead to a doubtful result by other researchers. A best practice is to follow what other authors are using as input parameters in their paper. This review analyses 72 proceeding papers and articles in different digital libraries: google scholar, IEEE Xplore, Elsevier, Springer, and snowball from 2010-2020. We present the result of our survey in this paper. We recommend the input parameters research should use base on the high utilisation as reference. Our review will help the community in MANET and Internet gateway to improve the credibility of the input parameters.

ZusammenfassungFür die Nutzung vorhandener Versorgungsdaten gibt es immer mehr gute Gründe, wobei v. a. die Nutzung von Registerdaten im Fokus steht. Das zugehörige, klar strukturierte methodische Vorgehen ist bisher noch unzureichend zusammengeführt, aufbereitet und transparent dargestellt. Das Deutsche Netzwerk Versorgungsforschung (DNVF) hat deswegen eine Ad hoc Kommission zur Nutzung versorgungsnaher Daten (RWE/RWD) ins Leben gerufen. Der vom IQWiG erstellte Rapid Report über die wissenschaftliche Ausarbeitung von Konzepten zur „Generierung versorgungsnaher Daten und deren Auswertung zum Zwecke der Nutzenbewertung von Arzneimitteln nach § 35a SGB V“ ist ein wesentlicher Schritt für die Nutzung von Registerdaten zur Evidenzgenerierung. Das vom DNVF 2020 veröffentlichte „Memorandum Register – Update 2019“ beschreibt Anforderungen und methodische Grundlagen von Registern. Best Practice Beispiele aus der Onkologie, die auf dem einheitlichen onkologischen Basisdatensatz für die Klinische Krebsregistrierung (§ 65c SGB V) beruhen, zeigen z. B., dass im Sinne einer wissensgenerierenden Versorgungsforschung mithilfe von Registerdaten Leitlinien überprüft sowie Empfehlungen für Leitlinien und notwendige Interventionen abgeleitet werden können. Gleichzeitig fehlen jedoch klare Qualitätsanforderungen und strukturierte formale und inhaltliche Vorgehensweisen in den Bereichen Datenzusammenführung, Datenprüfung und Nutzung spezifischer Methoden je nach vorhandener Fragestellung. Die bisher uneinheitlichen Vorgaben sollen aufgearbeitet und ein Methoden-Leitfaden zur Nutzung versorgungsnaher Daten entwickelt und veröffentlicht werden. Das erste Kapitel des Manuals zu Methoden versorgungsnaher Daten erläutert Zielstellung und Struktur des Manuals. Es wird dargelegt, warum die Verwendung des Begriffes „Versorgungsnahe Daten (VeDa)“ zielführender ist als die Nutzung der Begriffe Real Word Data (RWD) und Real World Evidence (RWE). Mit der Vermeidung des Begriffes „Real World“ soll insbesondere unterstrichen werden, dass auch qualitativ hochwertige Forschung auf Versorgungsdaten aufsetzen kann (z. B. registerbasierte vergleichende Studien).
