Background: The purpose of this study was to reveal any association between cardiorespiratory fitness level and excess post-exercise oxygen consumption (EPOC) using three cycling protocols with varying degrees of exercise intensity, i.e., sprint interval training (SIT), high-intensity interval aerobic training (HIAT), and continuous aerobic training (CAT). Findings. Ten healthy men, aged 20 to 31 years, attended a cross-over experiment and completed three exercise sessions: SIT consisting of 7 sets of 30-s cycling at 120% VO₂ with a 15-s rest between sets;HIAT consisting of 3 sets of 3-min cycling at 80∼90% VO₂ with a 2-min active rest at 50% VO₂ between sets;and CAT consisting of 40 min of cycling at 60∼65% VO₂. During each session, resting VO₂, exercise VO₂, and a 180-min post-exercise VO₂ were measured. The net exercise VO ₂ during the SIT, HIAT, and CAT averaged 14.7 ± 1.5, 31.8 ± 4.1, and 71.1 ± 10.0 L, and the EPOCs averaged 6.8 ± 4.0, 4.5 ± 3.3, and 2.9 ± 2.8 L, respectively. The EPOC with SIT was greater than with CAT (P < 0.01) and HIAT (P = 0.12). Correlation coefficients obtained between subjects' VO₂ and the ratio of EPOC to net exercise VO₂ for SIT, HIAT, and CAT were -0.61 (P = 0.06), -0.79 (P < 0.01), and -0.42 (P = 0.23), respectively. Conclusions: Our data suggest that cardiorespiratory fitness level correlates negatively with the magnitude of EPOC, especially when performing aerobic-type interval training. © 2012 Matsuo et al.;licensee BioMed Central Ltd.

Due to increasing demand, container terminals face the challenges of increasing its service capacity and minimize the time of ships loading and unloading. The assignment of storage locations for reshuffled containers is a problem to the efficiency of container terminals operations, as a wrong assignment may result in several future reshuffles. This paper proposes a meta-heuristic based on the Clonal Selection Algorithm to minimize reshuffle when retrieving containers from a stack. The model competitiveness in accuracy and time are established by extensive numerical experiments comparing with an existing Integer program model. The preliminary results obtained here suggest the proposed model is a promising optimization tool for the container stacking problem. © 2011 IEEE.

Background: Antidepressants are among the most commonly prescribed psychotropic agents for older patients. Little is known about the best source of pharmacotherapy information to consult about key factors necessary to safely prescribe these medications to older patients. Objective: The objective of this study was to synthesize and contrast information in the package insert (PI) with information found in the scientific literature about age-related changes of antidepressants in systemic clearance and potential pharmacokinetic drug-drug interactions (DDIs). Methods: A comprehensive search of two databases (MEDLINE and EMBASE from January 1, 1975 to September 30, 2011) with the use of a combination of search terms (antidepressants, pharmacokinetics, and drug interactions) was conducted to identify relevant English language articles. This information was independently reviewed by two researchers and synthesized into tables. These same two researchers examined the most up-to-date PIs for the 26 agents available at the time of the study to abstract quantitative information about age-related decline in systemic clearance and potential DDIs. The agreement between the two information sources was tested with κ statistics. Results: The literature reported age-related clearance changes for 13 antidepressants, whereas the PIs only had evidence about 4 antidepressants (κ < 0.4). Similarly, the literature identified 45 medications that could potentially interact with a specific antidepressant, whereas the PIs only provided evidence about 12 potential medication-antidepressant DDIs (κ < 0.4). Conclusion: The evidence-based literature compared with PIs is the most complete pharmacotherapy information source about both age-related clearance changes and pharmacokinetic DDIs with antidepressants. Future rigorously designed observational studies are needed to examine the combined risk of antidepressants with age-related decline in clearance and potential DDIs on important health outcomes

Hearing impairment was indicated as the second largest proven deficiency in world population. People with such disabilities face many obstacles in their communication and interaction with listeners, even with equal level of cognitive development. Collaborative tools offer the possibility to improve the interaction between listeners and hearing impaired subjects. This study presents an approach to support this type of interaction aimed to augment the participation of hearing impaired in collective activities. The approach has been materialized in a collaborative writing tool on which participants from both categories work together to produce a common document. The approach was evaluated by means of an experiment conducted with listeners and hearing impaired students in a learning environment. Analysis of the results obtained in the experiment show that the collaborative writing enhanced the interaction and contributes to a more harmonious and real coexistence among listeners and hearing impaired.

The use of nuclear power plants to produce electric energy is a safety-critical process where ultimate operational decisions still relies with the control room operators. Thus it is important to provide the best possible decision support through effective supervisory control interfaces. A human centered design approach, based on cognitive task analysis methods, was used to observe the operators training on the nuclear power plant simulator of the Human System Interface Laboratory (LABIHS). We noted deficiencies in graphic interface design, alarm system and in the integration between the computerized interfaces and the hardcopy (paper) procedures. A new prototype of the interface including graphics, alarms and digital procedures was designed as an alternative to the current hardcopy procedure manuals. The design improves upon the graphical layout of system information and provides better integration of procedures, automation, and alarm systems. The new design was validated by expert opinion and a performance comparison with the existing design.

Organizations have been relying on collaboration for productivity improvement and knowledge sharing. The first step to foster collaboration in organizations is to make it explicit. With this aim, the Collaboration Maturity Model (CollabMM) was proposed and evaluated. The lessons learned during model applications in previous work pointed out the need to review both the model and its evaluation instruments. A literature review also showed some improvement opportunities. Therefore, the objective of this work is to develop a roadmap to highlight the main opportunities of evolution in CollabMM. These opportunities will compose our research agenda in this topic and guide future work. © 2011 IEEE.

Applying a Goal programming Model to Support the Selection of Artifacts in a Testing Process

引用

Advances in Software Engineering 2012年第1期2012卷

作者： Andreia Rodrigues da Silva Fernando Rodrigues de Almeida Júnior Placido Rogerio Pinheiro Graduate Program in Applied Informatics University of Fortaleza (UNIFOR) Avenue Washington Soares 1321 60811-341 Fortaleza CE Brazilunifor.br

This paper proposes the definition of a goal programming model for the selection of artifacts to be developed during a testing process, so that the set of selected artifacts is more viable to the reality of micro and small enterprises. This model was based on the IEEE Standard 829, which establishes a set of artifacts that must be generated throughout the test activities. Several factors can influence the definition of this set of artifacts. Therefore, in order to consider such factors, we developed a multicriteria model that helps in determining the priority of artifacts according to the reality of micro and small enterprises.
