Miguel A. Ferreira, Daniel Ferreira, Clara C. Raposo

InHand - mobile professional context and location aware tool

Paulo A. C. S. Neves, David J. M. Ferreira, Daniel Esteves, Daniel R. M. Felix, Joel J. P. C. Rodrigues
2008 2008 16th International Conference on Software, Telecommunications and Computer Networks  
A travel book salesman needs current information that leads to the development of an information system about costumers, supplies, orders and the books themselves. Such scenario demands maximum mobility and rapid information retrieval that points to a mobile application. The paper presents an application developed for local and remote use, called InHand, that is context-aware, presenting information related to the current user context and provides location-aware support through the use of the
more » ... obal Positioning System (GPS). The location system keeps track of a client's location, schedules client visits for a given day, help user navigate through a map using real-time position acquisition, and gather the pathway followed by a user on a given day. The application has two channels: server and mobile client. The mobile client can synchronize data with the server, and relies on a local database to minimize wireless traffic to a minimum. We use Remote Data Access and Web Services to access remote data in a convenient way. Although the application is designed with book selling in mind, the concept is perfectly extendable to other fields of application.

2021 Gestão & Tecnologia de Projetos  
Housing is fundamental to the welfare of people and society. On the contrary, housing may impose costs on users as regards their health and quality of life. These costs are not only individual but also social. Studies on the concept of social costs (SCs) related to living conditions of social housing (SH) are scarce, and the concept needs in-depth debates. A systematic literature review (SLR) was conducted to answer the primary research question: What are SCs, and what triggers them? The
more » ... h specifically aims to identify spatial design factors and construction details of SH, which may cause adverse impacts and social costs and affect households' quality of life. The SLR results are analysed and discussed concerning the major concepts of SCs and social impacts (SIs). The visual representation and organization of data contribute to detailed and in-depth conceptual discussions to understand the factors that can induce actions to improve SH design and upgrading of the existing stock. Most publications emphasise physical and mental health risks. Poor thermal conditions cause illnesses, and depression is prevalent in many housing developments putting pressure on public systems and their health services. Social unrest and family conflict can impose further costs on policing and social assistance. Housing conditions' cause and effect are rarely detailed in the SC literature, which constitutes a research gap. New housing design, Upgrading or refurbishment initiatives should also effectively increase well-being, reduce environmental impacts, and ultimately contribute towards positive social and technological developments.
