This paper describes a case study of a student course about design for user experience. The theme of the course was emotionally loaded behaviour, brawling. Our objective was to teach, how to tackle a combination of emotional behaviour, user centered design approach and designer’s personal interpretation during product concept creation. The students were first introduced to the theme, then they ...

Objective: To evaluate the use of an adjustable venturi device with standard wall oxygen supply to deliver nasal high flow oxygen. Design: We set up a circuit using a standard 15 L/ min oxygen rotameter connected to a wall outlet, 2 m standard oxygen tubing, an adjustable venturi device, humidification chamber and nasal high flow circuit and cannulae. Delivered FiO2 and total gas flow rates wer...

Our aim is to give an account of the process carried out in the compilation of a multilingual lexicon of rural tourism terms. This lexicon provides equivalents of Spanish local culturally-loaded terms in English, French and Portuguese, the languages spoken by the vast majority of visitors to Castile and Leon. This tool will contribute to improve the communication in the catering industry in thi...

This study empirically investigated the influence of technology acceptance model factors, social influence factors and demographic factors on instant messaging adoption in the workplace. The research model addresses the need articulated by researchers to include social influence factors in the study of new technology adoption. An interesting finding is that in a factor analysis of the data, sub...

This paper examines combinations of complementary evaluation methods as a strategy for efficient usability problem discovery. A data set from an earlier study is re-analyzed, involving three evaluation methods applied to two virtual environment applications. Results of a mixed-effects logistic regression suggest that usability testing and inspection discover rather disjunctive sets of problems....

This paper presents a way to describe educational itineraries in a competence-oriented learning system in order to solve the problem of sequencing several independent courses. The main objective is to extract adaptive learning paths composed by the subset of needed courses passed in the right order. This approach improves the courses’ re-usability allowing courses to be included in different it...

Re-usability is frequently declared as sine qua non feature of modern ontology engineering. Although thoroughly examined in general theory of knowledge management models the re-usability issue is still barely a declaration in the domain of legal ontologies. The similar situation also applies to statutespecific ontologies. Those knowledge modeling entities are well described especially as an opp...

web information usability is a new issue, which has attracted many specialists in these days. it has been of great importance regarding the increasing growth of web sites requiring quality monitoring. web quality measurement has intrinsic difficulties and complexities, pushing specialists to devise automatic ways to measure its different aspects, among them usability and accessibility. this stu...

Database transformations is a critical task that occurs in many different domains. Schema evolution is one important class of problems for database transformations. In our work, we use existing technology and standards (ODMG, OQL, basic schema evolution primitives) to bring flexibility, extensibility and re-usability to current schema evolution systems, thus allowing the users to conveniently s...

The usability of code generators in industrial modeling frameworks is frequently hindered by long re-generation time imposed by complex dependencies between different modules and chains of code generation phases. Incremental model transformation techniques may improve both scalability and usability by regenerating only specific design artifacts dependent on a specific change. In this paper, I p...
