The Prescription Express System is a software program that was developed with express service of health care in mind. The purpose was to provide easy access for doctors to check on upcoming appointments with patients and send prescriptions via wireless network directly to the pharmacy to provide faster service.

The main purpose of this project is to provide an easy-to-use interface for students and faculty members to interact with each other during the course of a student's internship class.

Text in English / Scrum is the most adopted and under-researched Agile methodology. The research conducted on Scrum adoption is mainly qualitative. Therefore, there was a need for a quantitative study to investigate Scrum adoption challenges. The general objective of this study was to investigate the factors that have a significant relationship with Scrum adoption as perceived by Scrum practitioners working within South African organisations. To achieve this objective a narrative review to synthesise the existing challenges was conducted, followed by the use of these challenges in the development of a conceptual framework. After that, a survey questionnaire was used to test and evaluate the developed framework. The research findings indicate that relative advantage, complexity, and sprint management are factors that have a significant linear relationship with Scrum adoption. The findings are generalisable to the population, and the author recommends that organisations review the findings during their adoption phase of Scrum. / Council for Scientific and Industrial Research (CSIR) / University of South Africa (UNISA) / School of Computing / M.Sc.

The research reported in this thesis is an extension and application of the results first introduced by the Procedural Approach to the Evaluation of Software Development Methodologies. The evaluation procedure offers a unique perspective based on the philosophy that a software development methodology should espouse a set of objectives that are achieved by employing certain U principles throughout the software development process, such that the products generated possess certain attributes deemed desirable. Further, definite linkages exist between objectives and principles, and principles and attributes. The work described herein adopts the perspective offered by the evaluation procedure and applies a critical analysis to the process-product relationships in DoD-STD-2l67 and DoD-STD-2l68. In support of the analysis, Augmented Data Flow Diagrams are introduced as an effective tool for concisely capturing the information in both standards. The results of the analysis offer a deeper insight into the requirements for defense system software development, such that one is able to better understand the development process, and more intelligently assess the quality of the software and documentation produced. / Master of Science

The Unified Modeling Language (UML) became part of the curriculum in the Department of Computer Science at California State University, San Bernardino (CSUSB) in September 1997. The intent was to integrate the object-oriented paradigm in the undergraduate courses. Subsequently, this use has shifted to the graduate level. The purpose of this thesis is: 1) to determine what the students know about UML, 2) to reveal if the students were using UML, 3) to clarify how students use the UML.

The research is conducted in the area of software methodologies with the emphasis on the integration of legacy systems with the client/server environment. The investigation starts with identifying the characteristics of legacy systems in order to determine the features and technical characteristics required of an integration methodology. A number of existing methodologies are evaluated with respect to their features and technical characteristics in order to derive a synthesis for a generic methodology. This evaluation yields the meta primitives of a generic methodology. The revised spiral model (Boehm,1986; DuPlessis & Vander Wah,1992) is customised to arrive at a software process model which provides a framework for the integration of legacy systems with the client/server environment. The integration methodology is based on this process model. / Computing / M. Sc. (Information Systems)

Atualmente cerca de 15% da população mundial possui algum tipo de deficiência. Para estas pessoas o uso das tecnologias assistivas é essencial. A realidade aumentada surge como uma importante alternativa, para a criação de novas tecnologias assistivas, devido às suas inúmeras formas de rastreamento do participante, que, se combinadas, conseguem proporcionar novas possibilidades de interação. Entretanto, o uso da realidade aumentada, no contexto das tecnologias assistivas, não é uma panaceia, pois cada deficiência é única, assim como cada pessoa possui suas próprias particularidades. Portanto, é importante analisar a acessibilidade destas aplicações, para que o benefício do seu uso possa ser realmente assegurado. Esta dissertação propõe um modelo preditivo de avaliação, baseado no Design Universal e na norma ISO 9241-171. Este modelo é capaz de avaliar a acessibilidade de aplicações de realidade aumentada, quando usadas como tecnologias assistivas. O processo de avaliação consiste no preenchimento de questionários, compostos por questões claras e inteligíveis, para que possam atender à um público multidisciplinar, sem a exigência de qualquer conhecimento prévio em avaliação de acessibilidade. O produto da avaliação feita pelos questionários é um indicador de acessibilidade, que representa o grau de conformidade com os requisitos de acessibilidade. A aplicação dos questionários é sensível ao contexto, cada questionário inclui guias de utilização, que contém os requisitos mínimos do participante, para cada critério de avaliação, desta forma, é possível obter uma visão holística da avaliação, que pode ser customizada para cada participante ou generalizada para uma deficiência específica. O principal objetivo desta dissertação é propor um modelo preditivo, para a avaliação da acessibilidade, servindo aos educadores especiais, desenvolvedores e consumidores de tecnologias assistivas, como critério para a utilização ou não das aplicações de realidade aumentada. / Currently about 15% of the world population has some type of disability. For these people the use of assistive technologies is essential. Augmented reality emerges as an important alternative to the creation of new assistive technologies, due to its numerous forms of participant tracking, which, if combined, can provide new possibilities for interaction. However, the use of augmented reality in the context of assistive technology is not a panacea, as each disability is unique, as well as each person has its own peculiarities. Therefore, it is important to analyze the accessibility of these applications, to ensure the benefit of its use effectively. This work proposes a predictive evaluation model, based on universal design and ISO 9241-171 standard. This model is able to evaluate the accessibility of augmented reality applications, when used as assistive technologies. The evaluation process consists of completing questionnaires, composed of clear and intelligible issues, so that they can meet the multidisciplinary public, without requiring any prior knowledge in evaluating accessibility. The product of evaluation made by questionnaires is a numerical indicator of accessibility, which represents the degree of compliance with accessibility requirements. The questions are sensitives to context, each questionnaire includes guidelines, which contains the minimum requirements of the participant, for each criteria, it is thus possible to obtain a holistic view of the evaluation, which can be customized for each participant or generalized to a specific disability. The main objective of this work is to propose a predictive model for the evaluation of accessibility, serving special educators, developers and assistive technology consumers, as a criteria for the decision of use of augmented reality applications.

A modelagem é uma das atividades metodológicas presentes em processos de desenvolvimento de software e cumpre um papel relevante na fase de análise e projeto da solução. A linguagem de modelagem usual é a UML, porém ela é criticada por ser extensa e complexa. Outra possibilidade é fazer uso de diagramas livres, não existindo, entretanto, uma padronização nos elementos. Uma alternativa seria o uso da OPM, que representa a estrutura e comportamento de um sistema em um mesmo diagrama, utilizando uma notação única, além de possuir mecanismos intrínsecos para gerenciamento da complexidade. O objetivo deste trabalho é propor uma alternativa para modelagem de software em processos de desenvolvimento iterativo, incremental e ágil, visando aumentar a efetividade nesta atividade e colaborar na minimização das dificuldades encontradas nas atividades de análise e projeto de software, utilizando a OPM. A abordagem busca completude de modelagem, além de facilidade de compreensão e de aplicação e foi denominada PIASO – Projeto Iterativo, Incremental e Ágil de Software Utilizando a OPM. Uma avaliação da abordagem foi realizada por um grupo de 9 profissionais e os resultados mostraram que a percepção sobre a abordagem é que ela é fácil de entender e utilizar. Os dados obtidos com a avaliação mostraram que 67% dos participantes concordam que a abordagem seja de fácil entendimento e uso e 33% concordam parcialmente, além disso, os dados mostraram que a percepção quanto à utilidade da abordagem é positiva, 56% concordam que a abordagem seja útil e 36% concordam parcialmente. Finalmente, para ilustrar a utilização da abordagem, um estudo de caso foi executado, o qual indicou que para a visualização geral e modelagem da arquitetura do software o PIASO mostrou-se de fácil execução e interpretação, despendendo pouco tempo para sua realização, porém, para especificar algorítmos lógicos os diagramas da OPM não são tão eficazes. Outrossim, a característica iterativa da abordagem adaptou-se aos processos de desenvolvimento iterativos, incrementais e ágeis. / Modeling is one of the methodological activities in any software development process, mainly in the analysis and design phase. Usually the UML is used as modeling language, but it is criticized for being sprawling and complex. Informal visual conventions are also used, nevertheless, there is no single notation for the elements. OPM could be an alternative language because of its ability to express structure and behavior in a single diagram and complexity handling mechanisms. This paper presents a modeling approach using OPM in iterative, incremental and agile software development processes. The approach will intend to be not only complete, but easy to understand and apply. This approach was named PIASO, from the portuguese acronym for Iterative, Incremental and Agile Software Design using OPM. An evaluation of the approach was carried out by a group of professionals and the results show that the perception about the approach is that it is easy to understand and use. 67% out of the participants agreed that the approach is easy to understand and use and 33% agreed partially. In addition, the results show that the perception of the usefulness of the approach is positive, 56% out of the participants agreed that the approach is useful and 36% agreed partially. Finally, to illustrate the approach’s usage, a study case was performed, which indicated that for a software glance and architecture the PIASO was easy to execute and not time consuming, but to specify logical algorithms OPM diagrams are not so effective. Finally, PIASO’s iterative characteristic is naturally adapted to iterative, incremental, and agile software development processes.
