Alunos dos colégios técnicos cotil e cotuca já podem acessar serviços corporativos na nuvem UNICAMP

Como os colégios técnicos da Unicamp possuem sistemas próprios para cadastro de seus alunos, os dados não se integravam à base de dados corporativa da Unicamp (sistema SiSe / Serviço de Diretório LDAP), que consolida informações da DAC, DGRH e Funcamp. Com o objetivo de propiciar à comunidade de alunos dos colégios técnicos acesso aos diversos recursos já disponíveis na nuvem-Unicamp, o CCUEC, em conjunto com as equipes técnicas dos colégios, desenvolveu um método de comunicação (WebService) que permite que os dados dos alunos passem a integrar esta base de dados. Os seguintes produtos foram desenvolvidos: - Serviços na web (webservices) foram disponibilizados aos colégios técnicos para que possam enviar seus alunos ao LDAP corporativo da UNICAMP; - Disponibilizar aos colégios técnicos a possibilidade de uso de autenticação centralizada via serviço de diretório LDAP em suas aplicações. Como benefício, aos alunos dos colégios técnicos da Unicamp, podemos destacar: - No âmbito do acordo com a Google, de uso irrestrito de diversas ferramentas como Youtube, Gmail, Google Drive e também do ambiente Google Sala de Aula; - Recursos como acesso à rede sem fio, rede VPN, Botão de Pânico, Unicamp Serviços, entre outros disponibilizados na nuvem Unicamp; - Possibilidade de uso de par único de usuário e senha forte e segura para autenticação e acesso, via serviço de diretório (LDAP), em diversos sistemas institucionais do colégio técnico e da Universidade.

Towards just-in-time suggestions for log changes

Software developers typically insert logging statements in their source code to record runtime information. However, providing proper logging statements remains a challenging task. Prior approaches automatically enhance logging statements, as a post-implementation process. Such automatic approaches do not take into account developers' domain knowledge; nevertheless, developers usually need to carefully design the logging statements since logs are a rich source about the field operation of a software system. The goals of this paper include: i) understanding the reasons for log changes; and ii) proposing an approach that can provide developers with log change suggestions as soon as they commit a code change, which we refer to as "just-in-time" suggestions for log changes. In particular, we derive a set of measures based on manually examining the reasons for log changes and our experiences. We use these measures as explanatory variables in random forest classifiers to model whether a code commit requires log changes. These classifiers can provide just-in-time suggestions for log changes. We perform a case study on four open source projects: Hadoop, Directory Server, Commons HttpClient, and Qpid. We find that: (i) The reasons for log changes can be grouped along four categories: block change, log improvement, dependence-driven change, and logging issue; (ii) our random forest classifiers can effectively suggest whether a log change is needed: the classifiers that are trained from within-project data achieve a balanced accuracy of 0.76 to 0.82, and the classifiers that are trained from cross-project data achieve a balanced accuracy of 0.76 to 0.80; (iii) the characteristics of code changes in a particular commit and the current snapshot of the source code are the most influential factors for determining the likelihood of a log change in a commit.

Which log level should developers choose for a new logging statement?

Logging statements are used to record valuable runtime information about applications. Each logging statement is assigned a log level such that users can disable some verbose log messages while allowing the printing of other important ones. However, prior research finds that developers often have difficulties when determining the appropriate level for their logging statements. In this paper, we propose an approach to help developers determine the appropriate log level when they add a new logging statement. We analyze the development history of four open source projects (Hadoop, Directory Server, Hama, and Qpid), and leverage ordinal regression models to automatically suggest the most appropriate level for each newly-added logging statement. First, we find that our ordinal regression model can accurately suggest the levels of logging statements with an AUC (area under the curve; the higher the better) of 0.75 to 0.81 and a Brier score (the lower the better) of 0.44 to 0.66, which is better than randomly guessing the appropriate log level (with an AUC of 0.50 and a Brier score of 0.80 to 0.83) or naively guessing the log level based on the proportional distribution of each log level (with an AUC of 0.50 and a Brier score of 0.65 to 0.76). Second, we find that the characteristics of the containing block of a newly-added logging statement, the existing logging statements in the containing source code file, and the content of the newly-added logging statement play important roles in determining the appropriate log level for that logging statement.

Cardiac Rehabilitation for Aboriginal and Torres Strait Islander people in Western Australia.

BackgroundCardiovascular disease (CVD) is a leading cause of morbidity and mortality in Australia. Australian Aboriginal and Torres Strait Islander (Indigenous) people have higher levels of CVD compared with non-Indigenous people. Cardiac Rehabilitation (CR) is an evidence-based intervention that can assist with reducing subsequent cardiovascular events and rehospitalisation. Unfortunately, attendance rates at traditional CR programs, both globally and in Australia, are estimated to be as low as 10-30 % and Indigenous people are known to be particularly under-represented. An in-depth assessment was undertaken to investigate the provision of CR and secondary preveniton services in Western Australia (WA) with a focus on rural, remote and Indigenous populations. This paper reports on the findings for Indigenous people.MethodsCardiac rehabilitation and Aboriginal Medical Services (n = 38) were identified for interview through the Heart Foundation Directory of Western Australian Cardiac Rehabilitation and Secondary Prevention Services 2012. Semi-structured interviews with CR coordinators were conducted and included questions specific to Indigenous people.ResultsInterviews with coordinators from 34 CR services (10 rural, 12 remote, 12 metropolitan) were conducted. Identification of Indigenous status was reported by 65 % of coordinators; referral and attendance rates of Indigenous patients differed greatly across WA. Efforts to meet the cultural needs of Indigenous patients varied and included case management (32 %), specific educational materials (35 %), use of a buddy or mentoring system (27 %), and access to an Aboriginal Health Worker (71 %). Staff cultural awareness training was available for 97 % and CR guidelines were utilised by 77 % of services.ConclusionThe under-representation of Indigenous Australians participating in CR, as reported in the literature and more specifically in this study, mandates a concerted effort to improve services to better meet the needs of Indigenous patients with CVD as part of closing the gap in life expectancy. Improving access to culturally appropriate CR and secondary prevention in WA must be an important component of this effort given the high rates of premature cardiovascular disease affecting Indigenous people. Our findings also highlight the importance of good systematic data collection across services. Health pathways that ensure continuity of care and alternative methods of CR delivery with dedicated resources are needed.

Ranking of Palliative Care Development in the Countries of the European Union

ContextThere is growing interest in monitoring palliative care (PC) development internationally. One aspect of this is the ranking of such development for comparative purposes. ObjectivesTo generate a ranking classification and to compare scores for PC development in the countries of the European Union, 2007 and 2013. PC “development” in this study is understood as a combination of the existence of relevant services in a country (“resources”) plus the capacity to develop further resources in the future (“vitality”). Methods“Resources” comprise indicators of three types of PC services per population (inpatient palliative care units and inpatient hospices, hospital support teams, and home care teams). “Vitality” of PC is estimated by numerical scores for the existence of a national association, a directory of services, physician accreditation, attendances at a key European conference and volume of publications on PC development. The leading country (by raw score) is then considered as the reference point against which all other countries are measured. Different weightings are applied to resources (75%) and vitality (25%). From this, an overall ranking is constructed. ResultsThe U.K. achieved the highest level of development (86% of the maximum possible score), followed by Belgium and overall The Netherlands (81%), and Sweden (80%). In the resources domain, Luxembourg, the U.K., and Belgium were leading. The top countries in vitality were Germany and the U.K. In comparison to 2007, The Netherlands, Malta, and Portugal showed the biggest improvements, whereas the positions of Spain, France, and Greece deteriorated. ConclusionThe ranking method permitted a comparison of palliative care development between countries and shows changes over time. Recommendations for improving the ranking include improvements to the methodology and greater explanation of the levels and changes it reveals.

Survey on the Present State-of-the-Art of P2P Networks, Their Security Issues and Counter Measures

Peer-to-Peer (P2P) networks are quite different from traditional client-server networks. In P2P systems, all nodes are equal or peers and they can either act as client or server. All the nodes have similar capabilities. These networks became ubiquitous for file sharing and performing operations in distributed fashion. P2P networks are overlays on top of Internet or wide area network. P2P networks such as Gnutella, Napster, BitTorrent, and Freenet are some of the existing applications that allow sharing resources and searching for resources. Direct exchange of resources is made possible with P2P networks provided there are certain mechanisms such as directory service, distributed hash table, and flooding to discover services. P2P networks have the potential to enhance the capabilities of networks with sharing of music, video, and other services. Nevertheless, the P2P networks throw security challenges as the nodes are vulnerable to various attacks. In this paper we review the P2P networks, their security issues and counter measures. The attacks include DoS, DDoS, Man-in-the-Middle, Worm Propagation, Pollution Attack, Rational Attack, Sybil Attack and Index Poisoning Attack. This paper also provides counter measures of these attacks as available in the literature. The insights in this paper provide broad overview of P2P network issues and solutions.

Activity recommendation in intelligent campus environments based on the Eduroam federation

This paper presents a novel activity recommendation system based on the secure federated network Eduroam. The system, according to the users' profiles, is able to offer personalized information in a campus environment. The recommendation system uses a basic user's profile information from the directory services of Eduroam and an optional extended user's profile with advanced personal information provided from users. The system is able to recommend even with just only the basic infor- mation from Eduroam. Therefore, users can obtain recommendations without a prior configuration and they can still obtaining recommendations when they are visiting a foreign university within the Eduroam federation in a transparent way.

Improving Remote Method Invocation via Method Authorization and Elimination of Registry: An Exploration of Java and Haxe

Service availability in Java RMI (Remote Method Invocation) implementations can easily be compromised in a number of ways. One of the ways is when an attacker controls a directory service and mounts an attack on a RMI client and data. Stubs in a registry can be de- registered or overwritten by the attacker. In addition, he could register his own stubs as proxies to a server implementation. This project focuses on the security pitfalls of using default RMI implementation, namely the lack of access control mechanism to manage server methods (and objects) and limitations of RMI registry. The RMI registry is a weak point that could be exploited. This work addresses this concern by investigating RMI implementation and customizing the behavior to support client/method authorization, authentication and elimination of the need for an RMI registry. The contribution of this work is that it removes inherent vulnerability in RMI, which is due to weak security in RMI registry implementation. In addition, an emerging toolkit, Haxe, for platform-agnostic application development was introduced and its realization of RMI was briefly demonstrated. Haxe exhibits virtually all the features in Java and could be exploited like it. It however presents more promising features for the next generation of applications and services.

Responding to the health and rehabilitation needs of people with disabilities post-Haiyan.

It is estimated that 15% of the world's population has a disability, and disasters increase their risk and vulnerability. Rehabilitation services were limited in the area of the Philippines that was affected by Typhoon Haiyan. This study describes the initial rehabilitation needs assessment and activities to increase rehabilitation services conducted in Leyte province of Region 8 after Haiyan. A rehabilitation needs assessment for people with disabilities and injuries needing physical and functional rehabilitation care and assistive devices was conducted in health facilities, evacuation centres and selected municipalities in Leyte province between 9 November 2013 and 30 April 2014 by a consortium of agencies. Improvements to service delivery and referrals were documented. Rehabilitation services were reduced immediately after Haiyan, but they increased in the following months and peaked four months after Haiyan. There were 2998 individuals needing medicine and rehabilitation management, functional care and assistive devices. These included persons with pre-existing disabilities whose situations had worsened and people who had sustained injuries in the typhoon. Additional improvements included rehabilitation services with provision of assistive devices at the regional hospital, development of a directory of disability services in the region and advocacy through community-based rehabilitation. Information services and community knowledge for people with disabilities improved in Region 8 after Typhoon Haiyan, demonstrating that strengthening rehabilitation systems is a realistic goal after disasters.

E-services in e-business engineering

E-business engineering involves the study of evolving IT technologies and management science approaches to revolutionise e-business models and behaviors, and the demands from new e-business activities that prompt the development of new technologies and to make progress on management methods. In this essay, the scope of e-business engineering is illustrated and its importance to e-business is highlighted. Service-oriented computing (SOC) was chosen among numerous related topics for further analysis due to its role in the increasing popularity of cloud services and Internet of services (IoS) as they are hot commodities in e-business and important enabling technologies for e-business. The focus of this state-of-the-art review is on two SOC core technologies: service description language and service registries for service discovery and composition. A number of key frameworks and developments in the area are discussed in terms of their pros and cons and their associated challenges in the fast growing e-services marketplace. This essay also points out future developments and research directions to meet the related challenges, such as the standardization of service description and directory modelling, and the automated generation of annotation based on semantics and domain ontology.

CoAP 기반 센서네트워크를 위한 SWoT 서비스 탐색

On the IoT-based sensor networks, users or sensor nodes must perform a Service Discovery (SD) procedure before access to the wanted service. Current approach uses a center-concentrated Resource Directory (RD) servers or P2P technique, but these can cause a point-of-failure or flooding of SD messages. In this paper, we proposes an improved SWoT SD approach for CoAP-based sensor networks, which integrates Social Web of Things (SWoT) concept to current CoAP-based SD approach that makes up for weak points of existing systems. This new approach can perform a function like a keyword or location-based search originated from SNS, which can enhances the usability. Finally, we implemented a real system to evaluate.

Review of paediatric cardiology services in district general hospitals in the United Kingdom.

Following the Safe and Sustainable review of Paediatric Services in 2012/2013, National Health Service England recommended that local paediatric cardiology services should be provided by specially trained paediatricians with expertise in cardiology in all non-specialist hospitals. To understand the variation in local paediatric cardiology services provided across district general hospitals in the United Kingdom. An internet-based questionnaire was sent out via the Paediatrician with Expertise in Cardiology Special Interest Group and the Neonatologists with Interest in Cardiology and Haemodynamics contact databases and the National Health Service directory. Non-responders were followed-up via telephone. The response rate was 80% (141 of 177 hospitals), and paediatricians with expertise in cardiology were available in 68% of those. Local cardiology clinics led by paediatricians with expertise in cardiology were provided in 96 hospitals (68%), whereas specialist outreach clinics were held in 123 centres (87%). A total of 11 hospitals provided neither specialist outreach clinics nor any local cardiology clinics led by paediatricians with expertise in cardiology. Paediatric echocardiography services were provided in 83% of the hospitals, 12-lead electrocardiogram in 96%, Holter electrocardiogram in 91%, and exercise testing in only 47% of the responding hospitals. Telemedicine facilities were established in only 52% of the centres, where sharing echocardiogram images via picture archiving and communication system was used most commonly. There has been a substantial increase in the availability of paediatricians with expertise in cardiology since 2008. Most of the hospitals are well-supported by specialist cardiology centres via outreach clinics; however, there remains significant variation in the local paediatric cardiology services provided across district general hospitals in the United Kingdom.

Quality Open Access market and other initiatives: a comparative analysis

Recently academic publishing has entered in a new era, namely that of open access publishing. This has resulted in the appearance of numerous new open access journals. Scholars who want to publish their work today have endless publishing possibilities to choose from, but who is able to tell them which journal is reliable? This used to be the job of librarians, but with approximately 17000 journals they are no longer able to keep up. For this reason several websites and services have started to gather information about open access journals in order to make an overview of reliable and unreliable journals. One of these services is called Quality Open Access Market (QOAM). In this article six other services (Directory of Open Access Journals, JournalReviewer, SciRev, Journalysis, Journalguide, PRE-val and Eigenfactor) will be compared to QOAM in order to find out which service offers the best results. QOAM is taken as a starting point here because the research presented in this article was commissioned by them (namely: Saskia de Vries and Leo Waaijers) in order to find out what value they can actually add.

Co-designing a Digital Directory of Services

Abstract The Digital Health and Care Institute is a new innovation centre in Scotland which aims to transform health and social care delivery using a dynamic model of innovation ( www.dhi-scotland.com ). Experience Laboratories are at the core of this model and are led and developed by the Institute of Design Innovation at The Glasgow School of Art. Experience Labs provide a new way of working collaboratively within health and social care contexts in Scotland through a process of exploration, co-design and co-creation, and rapid prototyping of ideas. Bring together academic, business and civic partners, Experience Labs provide the opportunity for extreme collaboration in a safe and realistic environment. Through a series of design-led activities, which position the user at the centre of the design process, the Labs enable the trialing of ideas and co-design of sustainable health and social care solutions, together with end-users. This paper presents the findings of a design-led project to co-design a new directory of services application for the Scottish Ambulance Service. The Experience Lab aimed to explore and develop a basic prototype of a Directory App to support ambulance clinicians to consider alternatives to Accident and Emergency where appropriate, and support initial small scale testing. The Experience Labs provided the opportunity to co-design, develop and test a solution with users. The design-led approach enabled the delivery of a set of user-driven requirements for the development of the Directory App. The safe space for trialling and testing provided by the Labs together with the design-led approach allowed users to share their ideas and experience, contributing to the design of the ideal Directory App.

'Mind Your Own Business' - how can we best support employers to improve the mental health of their employees?

Despite the prevalence of mental distress within workplaces, health promotion workplace interventions have tended to focus on physical health,2,3 perhaps because employers understand this. Research with employers in the Yorkshire and Humber region revealed that despite stress and mental health problems being the most prevalent causes of sickness absence, only 33% of respondents provided mental health and stress reduction interventions, compared to 79% on exercise.4 From the perspective of employees, research from the Priory Group5 highlighted that fewer than three In ten people would tell their employer about their mental health condition.It is well documented that creating mentally healthy workplaces has benefits for employees and employers. Research from Business in the Community found that the Financial Times Stock Exchange (FTSE) 100 companies, which had robust arrangements for employee engagement and wellbeing, outperformed the rest of FTSE 100 companies by 10%.6Traditionally, where mental health interventions in the workplace have existed, they have tended to focus on individuals, relating to problems and not answering why and how interventions work.7 The recent report by the Chief Medical Officer8 commented that workplace strategies which were about prevention had not proved cost effective, and by focusing on risk, it may perversely lead to an increase in Illness reporting.The knowledge of how and why interventions are effective Is Important when considering the diversity of workplaces In the United Kingdom. Initiatives promoting mental health within workplaces need to be mindful of the uniqueness of organisations, their working climates and priorities.9 Resources, both financial and time, are limited within the public sector and with employers; therefore, learning should be shared to make best use of these limited resources.An increasing number of employers would like more support on mental health, and Rotherham employers expressed this same need.10 Rotherham's response was to deliver a project to assist workplaces to be mentally healthy places for all, help managers to support at risk people and create a positive attitude towards employing people with mental health problems. Mind Your Own Business (MYOB) was managed and delivered by National Health Service (NHS) Rotherham on behalf of Rotherham Strategic Partnership from 2008 to 2013, funded primarily by the Big Lottery Fund with additional funding from NHS Rotherham. MYOB was part of Altogether Better in Yorkshire and the Humber, a five-year regional-local collaborative programme aimed at building the region's capacity to empower communities to improve their health and wellbeing and to reduce health inequalities.MYOB had a particular focus on small and medium employers (SME) which have fewer resources than larger employers. During the period of the programme, MYOB worked directly with 1,679 individuals, 102 (72%) SMEs and 39 (28%) large employers, spanning the public, private and voluntary sectors.Employers were engaged by MYOB through third-party referrals from teams and agencies that linked with employers such as Rotherham Investment and Development Office (part of Rotherham Metropolitan Borough Council), Healthy Schools, Voluntary Action Rotherham and Being Better (which was a European funded project supporting businesses with health and financial management) and advertising.DELIVERY MODELThe level of Interventions depended on the needs of the employer. The project facilitator would, If requested, meet with the employer offering a needs assessment to assess their current working practices against evidence based practice. Various Interventions were offered:* Accredited Mental Health First Aid (MHFA) training;* Managing Mental Health: Skills for Line Managers training;* Directory of services;* Train the trainer courses;* Assistance to develop resources, for example, staff Intranet/leaflets;* Support with specific queries from employers; and* Learning events In response to National Policy; Fit Note and Equality Act briefings. …

Extracting REST resource models from procedure-oriented service interfaces

During the past decade a number of procedure-oriented protocols and standards have emerged for making service-offering systems available on the Web. The WS-* stack of protocols is the most prevalent example. However, this procedure and message-oriented approach has not aligned with the true potential of the Web's own architectural principles, such as the uniform identification and manipulation of resources, caching, hypermedia, and layering. In this respect, Resource Oriented Architectures based on the REST architectural style, have been proposed as a possible alternative to the operation-based view of service offerings. To date, compiling a REST API for back-end procedure-oriented services is considered as a manual process that requires as input specialized models, such as, service requirements and behavioral models. In this paper, we propose a resource extraction method in which service descriptions are analyzed, using natural language processing techniques and graph transformations, in order to yield a collection of hierarchically organized elements forming REST resources that semantically correspond to the functionality offered by the service. The proposed approach has been applied as a proof of concept with positive results, for the extraction of resource models from a sizable number of procedure-oriented Web Service interfaces that have been obtained from an open service directory.
