    YesWireless capsule endoscopy (WCE) has great advantages over traditional endoscopy because it is portable and easy to use, especially in remote monitoring health-services. However, during the WCE process, the large amount of captured video data demands a significant deal of computation to analyze and retrieve informative video frames. In order to facilitate efficient WCE data collection and browsing task, we present a resource- and bandwidth-aware WCE video summarization framework that extracts the representative keyframes of the WCE video contents by removing redundant and non-informative frames. For redundancy elimination, we use Jeffrey-divergence between color histograms and inter-frame Boolean series-based correlation of color channels. To remove non-informative frames, multi-fractal texture features are extracted to assist the classification using an ensemble-based classifier. Owing to the limited WCE resources, it is impossible for the WCE system to perform computationally intensive video summarization tasks. To resolve computational challenges, mobile-cloud architecture is incorporated, which provides resizable computing capacities by adaptively offloading video summarization tasks between the client and the cloud server. The qualitative and quantitative results are encouraging and show that the proposed framework saves information transmission cost and bandwidth, as well as the valuable time of data analysts in browsing remote sensing data.Supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (2013R1A1A2012904)

    UNIVERSITY OF LIÈGE, BELGIUM Executive Summary Faculty of Medicine Département Universitaire de Médecine Générale. Unité de recherche Soins Primaires et Santé Doctor in biomedical sciences Towards a system of concepts for Family Medicine. Multilingual indexing in General Practice/ Family Medicine in the era of SemanticWeb by Dr. Marc JAMOULLE Introduction This thesis is about giving visibility to the often overlooked work of family physicians and consequently, is about grey literature in General Practice and Family Medicine (GP/FM). It often seems that conference organizers do not think of GP/FM as a knowledge-producing discipline that deserves active dissemination. A conference is organized, but not much is done with the knowledge shared at these meetings. In turn, the knowledge cannot be reused or reapplied. This these is also about indexing. To find knowledge back, indexing is mandatory. We must prepare tools that will automatically index the thousands of abstracts that family doctors produce each year in various languages. And finally this work is about semantics1. It is an introduction to health terminologies, ontologies, semantic data, and linked open data. All are expressions of the next step: Semantic Web for health care data. Concepts, units of thought expressed by terms, will be our target and must have the ability to be expressed in multiple languages. In turn, three areas of knowledge are at stake in this study: (i) Family Medicine as a pillar of primary health care, (ii) computational linguistics, and (iii) health information systems. Aim • To identify knowledge produced by General practitioners (GPs) by improving annotation of grey literature in Primary Health Care • To propose an experimental indexing system, acting as draft for a standardized table of content of GP/GM • To improve the searchability of repositories for grey literature in GP/GM. 1For specific terms, see the Glossary page 257 x Methods The first step aimed to design the taxonomy by identifying relevant concepts in a compiled corpus of GP/FM texts. We have studied the concepts identified in nearly two thousand communications of GPs during conferences. The relevant concepts belong to the fields that are focusing on GP/FM activities (e.g. teaching, ethics, management or environmental hazard issues). The second step was the development of an on-line, multilingual, terminological resource for each category of the resulting taxonomy, named Q-Codes. We have designed this terminology in the form of a lightweight ontology, accessible on-line for readers and ready for use by computers of the semantic web. It is also fit for the Linked Open Data universe. Results We propose 182 Q-Codes in an on-line multilingual database (10 languages) (www.hetop.eu/Q) acting each as a filter for Medline. Q-Codes are also available under the form of Unique Resource Identifiers (URIs) and are exportable in Web Ontology Language (OWL). The International Classification of Primary Care (ICPC) is linked to Q-Codes in order to form the Core Content Classification in General Practice/Family Medicine (3CGP). So far, 3CGP is in use by humans in pedagogy, in bibliographic studies, in indexing congresses, master theses and other forms of grey literature in GP/FM. Use by computers is experimented in automatic classifiers, annotators and natural language processing. Discussion To the best of our knowledge, this is the first attempt to expand the ICPC coding system with an extension for family physician contextual issues, thus covering non-clinical content of practice. It remains to be proven that our proposed terminology will help in dealing with more complex systems, such as MeSH, to support information storage and retrieval activities. However, this exercise is proposed as a first step in the creation of an ontology of GP/FM and as an opening to the complex world of Semantic Web technologies. Conclusion We expect that the creation of this terminological resource for indexing abstracts and for facilitating Medline searches for general practitioners, researchers and students in medicine will reduce loss of knowledge in the domain of GP/FM. In addition, through better indexing of the grey literature (congress abstracts, master’s and doctoral theses), we hope to enhance the accessibility of research results and give visibility to the invisible work of family physicians

    This report is released at a time of renewed focus on the health and wellbeing of children and young people in Aotearoa. In April 2019 StatsNZ released the first round of child poverty statistics using a revised and more robust methodology. The same week saw the release of the first summary report on the national engagement undertaken in preparation of New Zealand’s first Child Youth and Wellbeing Strategy. There is a sense of careful hope in the child health and wellbeing sector that we may see steps toward the transformative change that is required for all children to enjoy the same opportunities to fulfil their potential. In this report the New Zealand Child and Youth Epidemiology Service (NZCYES) provides data and information to contribute to the effective planning and funding of services to improve, promote and protect the health and wellbeing of New Zealand children. The indicators of child health and wellbeing in this report cover the under-15 age group, with a focus on the school years. Indicators reported on in 2017 had a focus on the first five years of life. The 2019 report will extend further along the life course, to age 24 years

In April 2019 Stats NZ released the first round of child poverty statistics using a revised and more robust methodology.

There is a sense of careful hope in the child health and wellbeing sector that we may see steps toward the transformative change that is required for all children to enjoy the same opportunities to fulfil their potential. In this report the New Zealand Child and Youth Epidemiology Service (NZCYES) provides data and information to contribute to the effective planning and funding of services to improve, promote and protect the health and wellbeing of New Zealand children. The indicators of child health and wellbeing in this report cover the under-15 age group, with a focus on the school years. Indicators reported on in 2017 had a focus on the first five years of life. The 2019 report will extend further along the life course, to age 24 years. Indicator data for this report were extracted in 2018 from a range of routinely collected national datasets. For each indicator the report provides an analysis of the most recent data available at the time of writing, followed by evidence for good practice derived from current policies, guidelines and the evidence-based literature. Where possible, the evidence for good practice includes discussion of equity issues relevant to each indicator, to inform service planning and delivery. The 2018 report begins with a population snapshot comparing the population profile by age and gender in each district health board (DHB) with the national demographic profile. This helps to provide a context for the data presented in the report for specific indicators. Data should be interpreted in light of the differing patterns in age structure, ethnic composition, social and material deprivation in different regions and in Aotearoa overall. Equity is a key concern in child health. The Ministry of Health has a clear mandate to take a bold approach to addressing health inequities. The first review topic, Health equity, summarises recent publications from the Ministry of Health, organisations of health professionals, and scholarly literature with a focus on health equity between Māori and other children and young people in Aotearoa. It should be read in the light of the Waitangi Tribunal 2575 findings from stage one of the inquiry into nationally significant health issues [1]. Selected nutritional and physical activity indicators from the New Zealand Health Survey are presented in the healthy behaviours section of the report. These indicators are important for overall wellbeing, growth, and long-term health of children and young people. The second review topic, Children’s views on healthcare, reviews research on what children think about health services and how they are provided. This will help health service planners and providers to incorporate children’s views to make services more user-friendly and thereby more effective. The next two sections present data on oral health and immunisation, using a combination of community-based and hospitalisation data. An overview of all-cause hospitalisation follows, with detailed analysis of the more common causes of hospitalisation in this age group. Mental health analysis in this report presents data from the New Zealand Health Survey, and hospitalisation data for under-15 year olds with a mental health diagnosis. The opportunity to “grow up in a family environment of happiness, love and understanding” is a fundamental right of every child. The final section of this report includes indicators related to nurture and protection of children and young people. Data from the New Zealand Health Survey on physical punishment of children, and data from the National Collections on deaths and hospitalisations due to assault, neglect or maltreatment are included. The report appendices provide detail that may be helpful when interpreting information presented in the report. They include detailed descriptions of the methods used to develop evidence for good practice, and the statistical methods used in the data analyses, descriptions of the data sources used for the various indicators reported, explanation about classification of ethnicity and social and material deprivation in the report, and a list of the clinical codes relevant to each indicator. In summary, the 2018 report on health and wellbeing of under-15-year-olds presents data and interpretation on a set of relevant indicators extracted from national health datasets. The data used were the most recent available at the time of writing, and provide a snapshot of achievements and challenges in these areas. This report cannot address questions that require outpatient data, as these are not yet available at a national level. Developing systems that can provide a fuller picture of outpatient and primary health care data is important to inform child health service planning at national and DHB level. Reference 1.
