Distance learning is a learning style that can overcome the limitation of time and space. Because of the distance, teachers can not handle the student's learning situation, and they do not know whether the student is attentive, drowsy or absent. If teachers can know the student's affective state, they can overcome the difficult. The research applies the image recognition technologies to capture the face images of students when they are learning and analyzes their face features to evaluate the student's affective state by Fuzzy Integral. Finally, teachers can monitor the student's behavior by the detection results on the system interface.

In emergency response organizations with very limited resources, information technologies are not adequately explored. In such organizations, the simple adoption of new information technologies is not productive, as their efficient use depends on many other interrelated technologies. This work describes a model to help understanding these interrelationships. The model allows the cooperative evaluation of an organization through different perspectives. Using the model, an organization can measure its maturity level and guide the investment in emergency response capabilities. The information technology dimension of the model has been applied to the firefight organization in Brazil.

Learner attention affects learning efficiency. However, in many classes, teachers cannot assess the degree of attention of every student. When a teacher is capable of addressing inattentive students immediately, he can avoid situations in which students are inattentive. Many studies have analyzed student attentiveness by the applying of image detection technologies. If this mechanism can be applied to in-class learning, it will help teachers keep students attentive, and reduce teacher load during class. This study mainly applies fuzzy logic analysis of student facial images when participating in class. Applying fuzzy logic can prevent erroneous judgments associated with a single term, and help teachers deal with student attentiveness.

The Generation Challenge programme (GCP) is a global crop research consortium directed toward crop improvement through the application of comparative biology and genetic resources characterization to plant breeding. A key consortium research activity is the development of a GCP crop bioinformatics platform to support GCP research. This platform includes the following: (i) shared, public platform-independent domain models, ontology, and data formats to enable interoperability of data and analysis flows within the platform;(ii) web service and registry technologies to identify, share, and integrate information across diverse, globally dispersed data sources, as well as to access high-performance computational (HPC) facilities for computationally intensive, high-throughput analyses of project data;(iii) platform-specific middleware reference implementations of the domain model integrating a suite of public (largely open-access/-source) databases and software tools into a workbench to facilitate biodiversity analysis, comparative analysis of crop genomic data, and plant breeding decision making.

This work describes a workflow-based environment that manages the execution of software-testing processes. Testing processes require that human and computer resources be handled as dedicated resources, previously scheduled for testing activities, with no overlapping. Two striking features of this environment are: a) the efficient handling of resources by taking into account the capabilities offered by resources required by testing activities, and b) it provides a broader view of all execution steps in a software-testing plan. Hence, it enables a better planning of software-testing process executions, as well as of human and computer resources involved.

GOMS is a well-known model that has been successfully used in predicting the performance of human-computer interaction, identifying usability problems and improving user-interface design. The focus of GOMS on the individual user, however, explains why it has not been applied in the groupware context. We were inspired by GOMS to define a model that describes collaborative tasks in a formal way. We illustrate the application of the model by applying it to the design of a collaborative tool for software engineering requirements negotiation.

This paper presents a collaborative virtual environment for problem solving in civil engineering, which represents a building with problems related to its structural design (e.g., fissures). In this environment the students play the role of civil engineers. They need to detect the structural problems and evaluate their causes in order to be able to solve them. To accomplish this, the students can act upon the structural elements included in the environment (e.g., pillars) or make use of the working tools that are available (e.g., tape measure). This distributed environment allows for the exploration of the possibility of student collaboration in virtual reality. Furthermore, its design intends to provide a way to implement problem solving in collaborative environments in which genuine interdependence occurs i.e. team members must have different knowledge or abilities in order to create genuine collaboration.
