In this panel, we propose to figure out how requirements engineering and interaction design can be usefully combined. In particular, some people argue that scenarios/ use cases should be concrete, as in story-telling. Others argue for use of "essential" use cases as a methodological approach to interaction and user-interface design. Somewhat in the middle, it is argued that use cases should help acquiring the requirements in the first place. What should the practitioner believe and, in particular, do, in order to develop useful and usable software and systems? Software development and interaction design require different skills and different methods and are typically done by different people. Still, scenario-based design is proposed for several activities relevant for both tasks, such as requirements elicitation, software design, and interaction design. Symbolic modeling in this spirit is actually common to various fields. However, scenario-based approaches vary, especially with regard to their use, e.g., employing abstract use cases or integrating scenarios with functions and goals in a systematic design process. So, the key issue to be raised at the panel is how to combine different approaches, e.g., in scenario-based development, so that the interaction design as well as the development of the user interface and of the software internally result in an overall useful and useable system.

Assuring quality IT solutions demands assuring quality in all aspects of software development process. For this we need well-formed methods with suitable metrics with which we can verify if a process, software product, software component, software artifact or other part of possible solution meets defined quality characteristics. XML Schemas and corresponding XML documents are becoming the most important software artifacts. Today we can find large number of software metrics which are mostly used for software products. Very little has been done in field of metrics for XML Schema specification, especially metrics for evaluating XML Schemas quality. In this paper we will analyze existing XML metrics and their usage and try to hand out preliminary proposal for XML Schema quality framework.

Nowadays course navigation is mostly based on sequence order of pages prepared by the author of the course. Ontology based course navigation, where to every element of ontology some learning material is associated allows to effective navigation to desired information. Article is describing usage of keywords, which are searched in the learning material and keywords - ontology mapping for creating the course navigation. For every page two sets are created - prerequisite and outcome sets, where elements are elements of ontology. Implemented tool for creating this mapping and processing the material is described here.
This paper aims to obtain a baseline snapshot of Project Management processes using a two-phase questionnaire to identify both performed and nonperformed practices. The proposed questionnaire is based on the Level 2 p...

Software size is the fundamental metric for project planning. Effort and duration are calculated based on the size estimate. However, for a given software size, the actual development effort could be significantly different. The question is whether the increase in effort is due to the low productivity of the development team or higher product quality. While higher product quality is highly desirable and usually worth investing in, the reasons for additional effort might be elsewhere. In the research presented in this paper, the focus is on the correlation between code quality and productivity. Code quality is only one aspect of product quality. This paper presents a method for calculating a new type of project effort named "acknowledged effort". Acknowledged effort is calculated based on the actual effort and code quality. This new type of effort reflects not only the project's size and the productivity of the development team, but also the quality aspect of the delivered software system.
In this paper, we summarize our endeavor for spiral discovery of a separate prediction model from chronic hepatitis data. We have initially proposed various learning/discovery methods including time-series decision tr...

The equipment used for radiation hazard evaluation usually is based in measuring the total electric field strength over a frequency bandwidth of interest. However, because of the fact that the defined Reference Levels (RL) according to the ICNIRP Guidelines or other specific legislation are frequency dependent, the compliance of a particular RF or microwave transmitter and its contribution to the total received electromagnetic energy at a given measurement location is not easily identifiable. On the other hand, narrowband measurements can be used to determine the incident electric field from every single transmitter. However, in such a case, a large number of measurements are required in order to estimate its contribution to the total electric field strength and consequently to check for compliance with the legislation limits, due to the fact that directional antennas should be used. In this work a method is presented for determining: the total electric field from a particular direction to a specific point of a measurement location (e.g. in the vicinity of a mobile base station), the angle of maximum incident electric field and the total exposure quotient from the sources laying at that particular location in a frequency band of interest.
The natural neighbour interpolation is a potential interpolation method for multidimensional data. However, only globally C1 interpolants have been known so far. In this paper we propose a globally C2 interpolant, and...

The advancement of traffic makes world more and more internationalized and increases frequency of communication between people who come from different cultures. Differences in their conversation go beyond the languages they speak to the non-verbal behaviors they express while talking. To improve the abilities of the embodied conversational agents (ECAs) while interacting with human users we are working on the ECA based application, a tour guide of city Dubrovnik that servers visitors in Japanese, Croatian and general western cultures speaking in English. This paper presents the overall architecture and explains possible extension with another culture. It describes issues we met while making agent talk in Croatian and proposed solutions.
