Healthcare Critical Knowledge Monitor System Model : healthcare critical knowledge ontology component

“Proceedings of Safety, Health and Environment World Congress, ISSN 2317-3173. Vol. 13, nr. 1 (2013)”Healthcare organizations manage with personal information concerning to patients from many sources that, typically, are supported by computer-based systems therefore, demands cautious when there are ethical and legal aspects involved. Since not all clinical knowledge managed by healthcare organizations could be considered critical (or much critical) we need to define the value of clinical knowledge for further handle in risk management. With the key aspects of InfoSec: Confidentiality, Integrity, Availability and Privacy we intent to achieve the core critical knowledge that will be the source of the healthcare critical knowledge ontology. Critical knowledge ontology should be tailored to the healthcare organization in focus to comply with multiple factors, such as: organizational culture, terminology used, health department specifications, among others. With topic model approach we intent to automatically driven document topics and match with critical healthcare knowledge from ontology, thus, give value to the documents concerning its critical knowledge.This work is financed by FEDER funds through the Competitive Factors Operational Program – COMPETE and Portuguese national funds through FCT – Fundação para a ciência e tecnologia in project FCOMP-01-0124-FEDER- 022674

Critical Knowledge Monitor System Model: healthcare context

In order to provide a better service, sharing knowledge with partners and communities is becoming part of the healthcare organizations culture. Data, information and clinic knowledge require specific cautious, because it involves ethical and legal issues. The constant evolution of Information and Communication Technologies brings new opportunities with multiple forms of communication (web 2.0), therefore, new ways of sharing knowledge. Further, there is a wide knowledge sources: patient’s feedback; knowledge from Internet sources; knowledge from decision support systems; and inference knowledge (e.g. Knowledge from Data Mining techniques) justifying the use of knowledge management systems to get its benefits. The Critical Knowledge Monitor System Model, proposed here, allows knowledge sharing in a controlled ambient and could be a part of the answer to this paradigm that healthcare organizations face. To implement the Critical Knowledge Monitor System model we’ll need to apply knowledge engineering techniques such as ontology construction, text mining, techniques, Information retrieval, among others. Since not all knowledge manage by healthcare organizations could be considered critical (or much critical), it’s necessary to define constructs to classify clinic knowledge. To achieve this, we’ll implement a focus group approach with the use of risk management techniques to classify knowledge as critical and its critical level to driven ontology with the class and terms used by the healthcare organization under study. Essentially, these are the motives of this research.This work is financed by FEDER funds through the Competitive Factors Operational Program – COMPETE and Portuguese national funds through FCT – Fundação para a ciência e tecnologia in project FCOMP-01-0124-FEDER-022674

An ontology based approach to data surveillance

Nowadays the terrorist threat took proportions that concern governments and the national security organizations, all over the world. A successful terrorist incident usually brings catastrophic results. However if a terrorist attack can be predicted and characterized, it may be possible to organize a proper intervention in order to avoid it or to reduce its impact. The management of information is becoming an important issue in the domain of security information systems. The information access and association, analysis and assessment, and finally exploitation have become the focus for all security information services and governments. Current surveillance approaches are not very efficient leading innocent citizen to the confrontation of law enforcement services. One reason for this, result from the difficulties of the current system to extract knowledge or concepts abstracted from massive databases of information. Knowledge based methods, such as ontologies can integrate data surveillance, and enable a proper data analyse improving the performance of the security information services. This paper intends to present a perspective about the use of ontologies in the context of data surveillance, and present its importance in the current security services domain.(undefined

Análise in silico de genes envolvidos no transporte de nitrato, amônio e uréia em cafeeiro.

O nitrogênio (N) é o nutriente mais requerido pelo cafeeiro, sendo adquirido principalmente pelas raízes. As formas de N mais abundantes em solos agrícolas são nitrato (NO3-) e amônio (NH4+), enquanto que a uréia [CO(NH)2 O nitrato (NO] é a principal forma de N utilizada na adubação do cafeeiro. Devido a participação significativa da adubação nitrogenada nos custos de produção do café, é de interesse a identificação de genes envolvidos na absorção radicular e translocação de nitrogênio no cafeeiro, visando uma otimização da eficiência do uso do nitrogênio pela cultura. Neste trabalho foram encontradas etiquetas de sequências expressas (ESTs) no banco de dados do Projeto Genoma Café relacionadas ao transporte das formas mais relevantes na aquisição do N. O número de contigs/singlets para as diferentes famílias de transportadores decresceu na ordem: nitrato (NRT) > amônio (AMT) > uréia (DUR3). A maior expressão e diversidade de transportadores de nitrato refletem a importância desta forma de N na nutrição e fisiologia do cafeeiro, assim como na maioria das outras espécies de plantas

Zein/MnO2 Nanosheet Composites Integrated with a Smartphone for Colorimetric Sensors for On-Site Detection of Adulterants in Milk.

ABSTRACT: Milk and its derivatives are essential sources of nutrients for humans. However, the widespread adulteration of milk poses a significant challenge for ensuring the safety and integrity of these products. Here, a zein/manganese dioxide nanosheet (MnO2 NS) composite-based colorimetric sensor integrated with a smartphone platform was developed for on-site and quantitative analysis of hydrogen peroxide (H2O2) and lactic acid, two common adulterants in milk samples. Sensing platforms were fabricated by spraying composite solutions onto various costeffective and environmentally friendly substrates, including filter paper and masking tape, using a simple airbrush system. These platforms displayed remarkable sensitivity and suitable limit of detection (LOD) of 7.2 × 10−4 mol L−1 for H2O2 and 7.5 × 10−4 mol L−1 for lactic acid, respectively. These concentrations fall within the ranges established by diverse international regulatory bodies responsible for quality assurance protocols. Therefore, the dual detection of H2O2 and lactic acid in milk samples was successfully achieved in a rapid and cost-effective way, which opens possibilities for the design and implementation of field-deployable sensors for food safety surveillance and quality control

Frequency and damping of hydrodynamic modes in a trapped Bose-condensed gas

Recently it was shown that the Landau-Khalatnikov two-fluid hydrodynamics describes the collision-dominated region of a trapped Bose condensate interacting with a thermal cloud. We use these equations to discuss the low frequency hydrodynamic collective modes in a trapped Bose gas at finite temperatures. We derive a variational expressions based on these equations for both the frequency and damping of collective modes. A new feature is our use of frequency-dependent transport coefficients, which produce a natural cutoff by eliminating the collisionless low-density tail of the thermal cloud. Above the superfluid transition, our expression for the damping in trapped inhomogeneous gases is analogous to the result first obtained by Landau and Lifshitz for uniform classical fluids. We also use the moment method to discuss the crossover from the collisionless to the hydrodynamic region. Recent data for the monopole-quadrupole mode in the hydrodynamic region of a trapped gas of metastable $^4$He is discussed. We also present calculations for the damping of the analogous $m=0$ monopole-quadrupole condensate mode in the superfluid phase.Comment: 22 pages, 10 figures, submitted to Physical Review

Streaming contents and RSS feed in a pedagogical environment

A group of university teachers have been developing several contents using streaming technology, since it promotes the support of pedagogical activity as a dynamic resource and due to the fact that is oriented to a model of shared learning contents. Now, a new challenge can be stated: the share and the reutilization of these learning contents. Apart from being an enhanced experience only concerning the sharing of knowledge, it promotes a desired partnership inter/intra-department. In this context the RSS technology introduces a new dimension in the access to streaming media contents. The RSS is a format to syndicate contents enabling users to be aware of new contents that are periodically published. The RSS technology, through the use of RSS Aggregators or RSS Readers, help the user to keep up to date all their favourite information sources that provide their contents as RSS feeds. In the scope of the streaming media contents the definition of RSS feeds enable the students to be up to date of new educational resources that are provided by the teacher. Therefore the students instead of checking the updates that are published in several educational information resources can locally see the new resources that are described and provided in the RSS feed. Some preliminaries results are presented and discussed
