Mobile applications play an important role in many aspects of life. It is essential to be aware of the software development approaches that can support the design of accessible applications. Their main goal is to ensure that the interactive applications are available to everyone, including people with disabilities, reduced skills, or momentarily induced impairments. This paper aims to identify the accessibility barriers that occur when using design patterns for building user interfaces of mobile apps and propose guidelines to prevent the problems most often encountered. We start by conducting a gray literature review in professional forums and blogs to reveal the difficulties developers face when using mobile user interface design patterns. We thus compiled a catalog which contains the descriptions of 9 user interface design patterns, the accessibility barriers linked to the use of each pattern and the guidelines that can be followed to prevent the problem of these barriers. We carried out an evaluation of the use of the catalog with 60 participants. Our results show that in most cases, the guidelines were correctly applied for the prototyping of mobile user interfaces. The findings also revealed the usefulness and ease-of-use of the guidelines from the perspective of the participants.

The use of software reuse techniques in the context of business processes, such as Business Process Lines (BPL), makes viable the efficient reuse of business process models.In this context, it is highlighted the importance of computational support to aid the creation, instantiation and evolution of BPLs, once that the models created are complex due to the domain inherent characteristics and the dynamism of the business.The objective of this paper is to present an evolution to the BPL-Framework 1.0, tool responsible for creating BPLs, to also include the instantiation of this kind of line.The tool facilitates the resolution of variability throughout the instantiation and generates the instance automatically without human intervention.

Business process models enable to understand and improve the organization's business in order to stay competitive in the market. However, this artifact is not commonly elaborated due to time and costs associated. Thus, it was observed the importance of the practice of reutilization of business process models, making use of specific techniques such as the Business Process Line (BPL) that was originated from concepts of Software Product Line (SPL). As seen in SPL, in order to aid the creation, instantiation and evolution of BPLs, the usage of computational tools is also very important in the context of BPL, due mainly to the complexity and dynamism from businesses. Despite the growing academic interest in the area, no specific tools with support to build and document BPLs using features model, BPMN and BPMN* notations were found in the literature. This paper presents an Eclipse plug-in that supports the creation and documentation of BPLs, named BPL-Framework, which uses the aforementioned notations. Based on an evaluation done by individuals with different levels of knowledge about BPL, the BPL-Framework was considered to be satisfactory in relation to functional suitability (accuracy), operability (ease of use, learnability and attractiveness) and transferability (portability, adaptability and installability) from the ISO/IEC 25010.

This paper proposes an extension for the Business Process Model and Notation (BPMN), named BPMN*, that based on the elements of the feature model (FM), commonly used to represent variability, intends to represent variability in Business Processes Line (BPL).This notation is evaluated by means of an empirical study whose main objective is to compare it with other notation named variant-rich BPMN (vrBPMN) regarding the productivity and correctness of the business process model template (BPMT), which is one of the artifacts that compose a BPL.From the results it was possible to observe that the proposed notation allows the elaboration of BPMT with less errors, although modeling time was kept almost the same.

In recent years the use of free software has been considered in private enterprise, government agencies and end users. It is also remarkable the increase of projects and free software communities in Brazil. However, there are concerns about accessibility, because despite the growth in utilization and number of free software projects, accessibility is not always regarded in the software development process. In this article, we present the results of a study on accessibility in free software development that sought to identify how free software projects in Brazil are dealing with accessibility. Furthermore, we proposed changes in a specific process for the development of free software in order to insert accessibility elements.

The MPS.BR is a program to help improve the processes of software development mainly in small and medium-sized organizations, however it does not determine how processes should be defined to reach a certain degree of maturity. From another perspective, there is growing acceptance and records of success in the use of agile methods, mainly in MSEs (micro and small-sized enterprises of software development). Thus, it can be considered that both approaches can be used together to enable the implementation of lightweight processes and easily managed. In this context, this paper presents a process to support the implementation of MPS.BR together with agile practices in MSEs, called IAMPS, and discusses the main results obtained with its application in an initial project of software process improvement deployment in the public sector.

The increasing volume of research projects on applied computing is a motivation for analyzing processes which are used to develop such projects. There are significative differences between research projects on applied computing and industrial software projects, for example, in research domain there is the interest in prototype development instead of product development. As a consequence,definition of specific processes to attend this context is required. Additionally, these processes are relevant because, with the wide spread of the Internet, many researchers are working on collaborative projects from geographically distant areas and an adjusted process can help management overtime of artifacts like models, prototypes, and scientific documents. In this paper, the goal is to provide a comparative review of processes for research development on applied computing, based on requirements described in the literature. He hope that results of this review be useful to help researchers to select one approach or defining their own process.

This paper discusses an approach for Web accessibility education tacking advantage of short introductory courses. In this approach, screen readers were used toallimmerse students in the problems experienced by blind users while using the Web. Experimental results from an evaluation exercise carried out by students showedallthat the use ofallscreen readers was helpful to better understand and to reinforce the concepts of Web accessibility.
