PP27 Features of emergency medical system calls that facilitate or inhibit call-taker recognition that a patient is in, or at risk of, cardiac arrest: a systematic mixed studies review

AimTo identify and appraise evidence relating to the features of an Emergency Medicine System call interaction that enable, or inhibit, an Emergency Medical Dispatcher’s recognition that a patient is in out-of-hospital cardiac arrest, or at imminent risk of out-of-hospital cardiac arrest.MethodsAll study designs were eligible for inclusion. Data sources included Medline, BNI, CINAHL, EMBASE, PubMed, Cochrane Database of Systematic Reviews, AMED and OpenGrey. Stakeholder resources were screened and experts in resuscitation were asked to review the studies identified. Studies were appraised using the Mixed Methods Appraisal Tool. Synthesis was completed using a segregated mixed research synthesis approach.ResultsTwenty-five studies were included in the review. ‘Recognition studies’ involving patients already in out-of-hospital cardiac arrest dominated this SMSR and challenges associated with recognition of out-of-hospital cardiac arrest were apparent. Four main themes were identified: Recognising abnormal/agonal breathing during the emergency call, Managing the emergency call, Emotional distress, Patient’s colour.ConclusionA dominant finding is the difficulty in recognising abnormal/agonal breathing during the Emergency Medical Service call. The interaction between the caller and the Emergency Medical Dispatcher is critical in the recognition of patients who suffer an out-of-hospital cardiac arrest. Emergency Medical Dispatchers adapt their approach to the Emergency Medical Service call, and regular training for Emergency Medical Dispatchers is recommended to optimise out-of-hospital cardiac arrest recognition. Further research is required with a focus on the Emergency Medical Service call interaction of patients who are alive at the time of the Emergency Medical Service call and who later deteriorate into OHCA.

Mathematical Analysis of Improving the System Capacity and Signal to Interference Ratio in Cellular Mobile Communication

The most important index for Quality of Service is call drop which has not been accurately discussed before. Sometimes the network disconnects while talking on the phone, this disconnection is called a dropped call. The level of call drop of mobile operators in the every country has increased significantly lately. As a result, thousands of mobile phone users are suffering. To reduce call drop, at first the factors causing call drop have identified in this paper. Based on these factors, dropped call model has developed to find out the parameters associated with call drop. Then some existing techniques have analyzed mathematically to improve the different parameters of these factors to reduce call drop. Three main factors have identified from the developed dropped call model causing call drop such as the lack of available channels, the poor signal quality and the handover failure. In this paper, mathematical analysis of cell splitting, cell sectoring and Microcell zone concept have provided to support extra connecting demand, ongoing service and to improve the signal to interference ratio. Also queuing handoff will be analyzed mathematically with justification to avoid disturbing service call drop. Simulation of mathematical model of these call drop reduction techniques has performed using MATLAB software.

(a draft of) Non-secure Client Awareness in TF-M

<div>This paper presents a novel mechanism implemented in the SW to identify and authorize secure service call from the NW. While the current solution needs changes of the non-secure software (typically an RTOS), our solution exploits available hardware (i.e., the memory protection unit or MPU) to handle clients identification and authorization in a transparent way to non-secure software.</div>

Identification of the Use of Unauthorized Apps in the O2O Service by Combining Online Events and Offline Conditions

A model for detecting unauthorized Apps use events by combined analysis of situation information in an offline service and user behavior in an online environment is proposed. The detection and response to abnormal behavior in the O2O service environment can be focused on providers, whose decisions change dynamically based on the offline market status and conditions. However, the method for identifying the user’s tools and detecting the usage pattern of the service user were developed in the existing online service environment. Thus, in order to identify abnormal behavior in the O2O service environment, we conducted an experiment to identify the abnormal behavior of providers of smart mobility services, a representative O2O service. In the experiment, the range of normal behavior of a taxi drivers was identified, which was prepared on the basis of the test result directly executed by an expert. The optimal features were selected in order to effectively detect abnormal behavior from the event data relating to the service call acceptance behavior. In addition, by processing the collected data based on the selected features by using various machine-learning classification algorithms, we derived a detection and prediction model that is 98.28% accurate with a prediction result of more than 74% based on the F1 score. Based on these results, we expect to be able to respond to abnormal behavior that may occur in various types of O2O services.

IMPLEMENTASI MODEL PEMURIDAN KONTEKSTUAL SEBAGAI PANGGILAN PELAYANAN TERHADAP GENERASI MILENIAL DI ERA INDUSTRI 4.0

ABSTRAK - Arus globalisasi yang mendunia sudah tidak dapat dibendung lagi keberadaannya di negara Indonesia. Indonesia menjadi salah satu dari berbagai negara yang telah dipengaruhi oleh perkembangan teknologi dan iptek yang semakin canggih, sehingga dunia kini telah memasuki era industri 4.0. Generasi milenial adalah salah satu kelompok yang dipengaruhi oleh perkembangan teknologi yang serba instan, bahkan peran penting generasi milenial sudah mulai surut tergantikan oleh kemajuan teknologi. Menghadapi tantangan tersebut diperlukan solusi yang solutif yaitu mengimplementasikan model pemuridan kontekstual sebagai panggilan pelayanan terhadap generasi milenial di era industri 4.0, sehingga membentuk generasi milenial supaya beridentitas Kristen dan bertumbuh menjadi dewasa dalam iman. Pendekatan yang dilakukan adalah dengan pendekatan kualitatif yang melibatkan studi pustaka. Penelitian ini menghasilkan kesimpulan bahwa model pemuridan kontekstual layak dijadikan pedoman dalam mengarahkan para generasi milenial di era indutri 4.0 agar mampu bertahan (survive) dalam perkembangan zaman yang semakin canggih.Kata kunci : Pemuridan, Kontekstual, Panggilan Pelayanan, Generasi Milenial, Revolusi Industri 4.0ABSTRACT - The current global globalization can not be dammed anymore its existence in the country of Indonesia. Indonesia has become one of a variety of countries that have been influenced by increasingly sophisticated technological and technological developments, so that the world has now entered the industrial era 4.0. Millennials have become one of those groups influenced by the development of instantaneous technology, even the important role of millennials has begun to subside replaced by technological advances. Facing these challenges requires a solution that is to implement a model of contextual discipleship as a service call to millennials in the industrial era 4.0, thus forming millennial generations so that Christian identity and growing into adulthood in the faith. The approach taken is a qualitative approach that involves the study of literature. This research concludes that the contextual discipleship model deserves to be used as a guideline in directing millennial generations in the 4.0 industry era to be able to survive in the development of increasingly sophisticated times.Key Words : Discipleship, Contextual, Service Call, Milennial Generation, Industrial Revolution 4.0
