AbstractThe rapid evolution of the Internet of Things (IoT) is making way for the development of several IoT applications that require minimal or no human involvement in the data collection, transformation, knowledge extraction, and decision-making (actuation) process. To ensure that such IoT applications (we term them autonomic) function as expected, it is necessary to measure and evaluate their quality, which is challenging in the absence of any human involvement or feedback. Existing Quality of Experience (QoE) literature and most QoE definitions focuses on evaluating application quality from the lens of human receiving application services. However, in autonomic IoT applications, poor quality of decisions and resulting actions can degrade the application quality leading to economic and social losses. In this paper, we present a vision, survey and future directions for QoE research in IoT. We review existing QoE definitions followed by a survey of techniques and approaches in the literature used to evaluate QoE in IoT. We identify and review the role of data from the perspective of IoT architectures, which is a critical factor when evaluating the QoE of IoT applications. We conclude the paper by identifying and presenting our vision for future research in evaluating the QoE of autonomic IoT applications.

Cloud computing has significantly enhanced the growth of the Internet of Things (IoT) by ensuring and supporting the Quality of Service (QoS) of IoT applications. However, cloud services are still far from IoT devices. Notably, the transmission of IoT data experiences network issues, such as high latency. In this case, the cloud platforms cannot satisfy the IoT applications that require real-time response. Yet, the location of cloud services is one of the challenges encountered in the evolution of the IoT paradigm. Recently, edge cloud computing has been proposed to bring cloud services closer to the IoT end-users, becoming a promising paradigm whose pitfalls and challenges are not yet well understood. This paper aims at presenting the leading-edge computing concerning the movement of services from centralized cloud platforms to decentralized platforms, and examines the issues and challenges introduced by these highly distributed environments, to support engineers and researchers who might benefit from this transition.

In recent years, there has been significant advancement in resource management mechanisms for cloud computing infrastructure performance in terms of cost, quality of service (QoS) and energy consumption. The emergence of the Internet of Things has led to the development of infrastructure that extends beyond centralised data centers from the cloud to the edge, the so-called cloud-to-thing continuum (C2T). This infrastructure is characterised by extreme heterogeneity, geographic distribution, and complexity, where the key performance indicators (KPIs) for the traditional model of cloud computing may no longer apply in the same way. Existing resource management mechanisms may not be suitable for such complex environments and therefore require thorough testing, validation and evaluation before even being considered for live system implementation. Similarly, previously discounted resource management proposals may be more relevant and worthy of revisiting. Simulation is a widely used technique in the development and evaluation of resource management mechanisms for cloud computing but is a relatively nascent research area for new C2T computing paradigms such as fog and edge computing. We present a methodical literature analysis of C2T resource management research using simulation software tools to assist researchers in identifying suitable methods, algorithms, and simulation approaches for future research. We analyse 35 research articles from a total collection of 317 journal articles published from January 2009 to March 2019. We present our descriptive and synthetic analysis from a variety of perspectives including resource management, C2T layer, and simulation.

Purchasing Process

O presente estudo aborda através de uma revisão de literatura, de caráter descritivo, a importância do método de padronização no processo de compra, considerando as perceptíveis dificuldades encontradas neste setor, como falta de embasamento técnico quanto aos modelos de compra utilizados, na aquisição de artigos médico-hospitalares, culminando em desperdícios por baixa qualidade, ou ainda por utilização equivocada aliada à falta de  treinamento,  devido  trocas  constantes de  materiais. Nesse contexto, acrescenta-se o papel do enfermeiro como executor, ressaltando a importância do mesmo na unidade hospitalar. Desta forma, este estudo apresenta ferramentas para contribuir dentro desse cenário, agregando conhecimento teórico, científico e legal, que possa ser utilizado durante o desenvolvimento da atividade em instituições de saúde, visando racionalizar os gastos e aperfeiçoar os  recursos e serviços.  A realização deste estudo permite compreender a importância da padronização no processo de compra e seus benefícios juntamente com a participação do enfermeiro na aquisição dos materiais para a inserção de qualidade no âmbito hospitalar. ABSTRACT: The present study addresses, through a literature review of a descriptive character, the importance of the standardization method in the purchase process of nursing materials and equipment, considering the perceived difficulties in this sector, such as the lack of technical purchase for medical and hospital articles, causing waste due to poor quality, misuse due to constant change of models and lack of training to handle them. In this context, it is verified the fundamental role of the nurse as an executor in emphasizing its importance in the hospital unit with tools and theoretical, scientific and legal knowledge for the development of its activities in health institutions, with the objective of rationalizing the expenditures and resources and improve services. Therefore, this study aims to highlight the importance of nurses' standardization and performance in the purchasing process, focusing on the insertion of quality in the hospital context. With the survey carried out, it can be concluded that the participation of the nursing professional in the standardization of the purchasing process, makes the management of medical and hospital resources more efficient by identifying the quantity and quality of materials needed for health professionals to perform their Risk-free activities for you and your patients. As a suggestion for future research, new research on the subject is indicated for the mapping of critical factors of quality success in medical-hospital procedures based on the use of materials and equipment to support the nursing service.

Background: Anal fissure (AF) is a common disease associated with severe pain and reduced quality of life. Factors related to lifestyle, including diet and bowel habits, play a pivotal role in its pathogenesis. Most of the chronic fissures are not responsive to drugs and more likely to recur. Given the significance of diet in Persian medicine (PM), investigation on physiopathology and appropriate foods can be useful for decreases in AF symptoms and consequences. Objective: This study was intended to evaluate the role of diet in the formation and progression of AF from the perspective of PM. Methods: In this study, the most important resources of PM dating back to thousands of years were reviewed. All these textbooks contained a section on AF, its causes, and treatment. Further analysis was performed on these resources in comparison with databank and resources of modern medicine to develop a food-based strategy for AF management. Results: From the view of PM, the warmth and dryness of anus temperament accounted for AF. Both Persian and modern medicine identified constipation as another cause for AF. Therefore, avoidance from some foods and commercial baked goods was recommended. Both Persian and modern medicine forbad the following foods: potato, cabbage, cauliflower, pasta, beef, fish, and so forth. High fiber and oligo-antigen diets with some limitations have garnered more attention. Conclusion: An integrative approach is recommended employing both Persian and modern medicine for AF. There have been some evidence in this regard, however standardized clinical trials are required for future research.

Comprehension Tests

Reciprocal teaching is an instructional procedure designed to teach students cognitive strategies that might lead to improved reading comprehension. The learning of cognitive strategies such as summarization, question generation, clarification, and prediction is supported through dialogue between teacher and students as they attempt to gain meaning from text. This article is a review of sixteen studies on reciprocal teaching, which include published studies found in journal articles and unpublished studies indexed in Dissertation Abstracts International. All the studies included in this review were quantitative in methodology. When standardized tests were used to assess comprehension, the median effect size, favoring reciprocal teaching, was .32. When experimenter-developed comprehension tests were used, the median effect size was .88. We also discuss the role of cognitive strategies in enhancing comprehension, the strategies that were most helpful, instructional approaches for teaching cognitive strategies, the quality of the dialogue during reciprocal teaching, and suggestions for future research and practice.

Background and Purpose: The absence of psychogeographical awareness is a critical factor contributing to the lackadaisical attitudes towards the place and its environment. As a result, it enables an individual to fully experience a location, both physically and intellectually, while also gaining a feeling of self-discovery and self-realisation.   Methodology: The purpose of this study was to examine the responses of a group of individuals who participated in a field observation. 40 participants from a Malaysian university's foundation level were brought to Malacca to experience the environment's geographical scenery at their own leisure. The survey data was then manually transcribed and analysed in accordance with the study's aim.   Findings: Interactions with individuals and observation of features in the countryside and urban surroundings enabled participants to go on a psychogeographical journey that influenced their way of thinking and behaving. All participants felt that the journey had influenced their experiences and perspectives on their thinking and behaviour, highlighting the critical role of this notion in establishing the connection between place and self.   Contributions:  The findings of this study provide a solid foundation for future research in the field of psychogeography. The data may be used as a baseline for future studies to determine whether a comparable impact exists in other locations, with or without significant features like those found in Malacca.   Keywords: Psychogeography, place attachment, place meaning, self-discovery, Malacca.   Cite as: Khaidzir, M.

Connected and automated vehicle (CAV) technologies and services are rapidly developing and have the potential to revolutionise the transport systems. However, like many innovations, the uptake pathways are uncertain. The focus of this article is on improving understanding of factors that may affect the uptake of highly and fully automated vehicles, with a particular interest in the role of the internet of things (IoT). Using system dynamic modelling, sensitivity testing towards vehicle attributes (e.g., comfort, safety, familiarity) is carried out and scenarios were developed to explore how CAV uptake can vary under different conditions based around the quality of IoT provision. Utility and poor IoT are found to have the biggest influence. Attention is then given to CAV ‘services' that are characterized by the attributes explored earlier in the paper, and it is found that they could contribute to a 20% increase in market share.
