An ICT tool is not only used in healthcare as an aid for caregivers, but can also help enhance the care experience of care recipients as these tools can bring benefit to the recipient. The positive care experience can also have the opposite effect, depending on the quality of information conveyed to the recipient. This study deals with SMS reminders information related to the quality of the care experience. It examines whether SMS reminders within the health system contains sufficient quality information to influence recipients care experience to the positive. This study was conducted by a qualitative method of semi-structured interviews with both care recipients and caregivers. This is to get two different perspectives on the information and quality care experience – from a care recipients perspective as receiving the SMS reminder, and from a caregivers perspective that send out the SMS reminders. By conducting a literature review, we acquired material that formed the basis of our interview questions. The results of the study show that SMS reminders in the current situation does not contain sufficient high quality information in order to reach a positive care experience for patients. In addition to information quality, we have also identified communication as a major factor contributing to increasing health care experience. Besides these two factors, we could also deduce that health care consumers have different needs depending on the life situation they are in.

A preocupação ambiental dos executivos das Empresas é dirigida a todas as partes interessadas como empregados, acionistas, clientes, fornecedores, comunidades, órgãos legisladores e governo, os chamados stakeholders. O desenvolvimento sustentável deve satisfazer as necessidades da geração presente sem comprometer a vida das gerações futuras. Portanto, a questão central da sustentabilidade é o balanceamento da proteção ambiental com o desenvolvimento social e econômico. Este desenvolvimento deve combinar crescimento econômico com mudanças sociais e culturais, reconhecendo os limites impostos pelos ecossistemas, e desta maneira as considerações ambientais sejam incorporadas por todas as partes interessadas. Este trabalho pesquisa na literatura os conceitos de desenvolvimento sustentável, responsabilidade social corporativa, eco-eficiência, sistema de gestão ambiental, governança corporativa e identifica as necessidades de uma corporação para atendimento àqueles conceitos. Estuda a gestão da Refinaria Presidente Bernardes de Cubatão, elenca as ações e projetos para atendimento àqueles conceitos e compara as grades de projetos com as necessidades teóricas da literatura. Entrevista outras partes interessadas como o gerente geral da refinaria, o secretário da Indústria, Comércio, Porto e Desenvolvimento de Cubatão, o Promotor Público de Cubatão e a CETESB para, à luz dos depoimentos e dos projetos da refinaria, concluir se uma refinaria de petróleo pode ser sustentável.

Para a realização dessa pesquisa foi desenvolvido um estudo da espessura crustal nos Andes setentrionais e na parte norte dos Andes centrais (entre 10ºN e 9ºS). Foram usadas reflexões da Moho de seis sismos de profundidade média para achar a espessura crustal na área de estudo. As ondas pmP e smS (reflexões na Moho) são encontradas como precursoras das fases profundas pP e sS de sismos registrados em estações localizadas a distâncias telessísmicas. A metodologia utilizada exigia sismos com profundidade maiores que 100 km e magnitude maiores que 6. Entretanto, devido à baixa amplitude apresentada pelas ondas pmP e smS, foi necessário realizar um empilhamento de vários sismogramas para realçar as chegadas das ondas analisadas. A área estudada foi dividida em três partes: área norte entre 6ºN e 0º(na Colômbia), área central entre 2ºS e 5ºS (no Equador) e área sul entre 6ºS e 9ºS (na borda entre Peru e Brasil). Na área norte foram encontradas espessuras crustais entre 26 e 56 km em quatro pontos de reflexão de dois sismos; na área central foram encontradas espessuras da crosta entre 40 e 63 km para três pontos de reflexão de um sismo; finalmente, na região sul, foram encontradas espessuras crustais entre 35 e 40 km para 7 pontos de reflexão de 3 sismos. Foi obtido a relação Vp/Vs = 1.79 ± 0.16 para a região norte dos Andes, usando as diferenças de tempo sS-smS e pP-pmP. Os resultados obtidos vão aumentar o banco de dados de espessura crustal nos Andes setentrionais e na parte norte dos Andes centrais, como também possibilitaram uma melhora do modelo de espessura crustal desenvolvido por Assumpção et al. (2013) para América do Sul, permitindo assim a analise e comparação entre os dados obtidos nesse estudo e o modelo crustal de Assumpção et al. (2013). / In this work we studied the crustal thickness in northern Andes and northern central Andes (between 10ºN and 9ºS). We analyzed the reflections from the underside of the Moho for six intermediate earthquakes occurred in the study area to estimate the crustal thickness at the bounce point. The pmP and smS phases (reflections at the Moho) are identied as precursors to the depth phase pP and sS, respectively, when recorded at teleseismic distances. This method require events of magnitude > 6 and depth > 100 km. In order to better identify those two reflections, it was necessary to stacking traces from different stations. The study area was divided in three sections: northern area between 6ºN - 0º (Colombia), in this area we analyzed two earthquakes and the crustal thicknesses in four bounce points were found; central area between 2ºS- 5ºS (Ecuador), in this area we studied one earthquake and the crustal thicknesses in three bounce points were found; southern area between 6ºS - 9ºS (Peru-Brazil border), where we analyzed three earthquakes and the crustal thicknesses in seven bounce points were found. Crustal thickness found in the southern area varied from 35 to 40 km, from 40 to 63 km in the central area and from 26 to 56 km in the northern area. We estimated a Vp/Vs ratio of 1.79±0.16 for the northern Andes using the time differences sS-smS and pP-pmP relation. Our analysis complements the data base of Moho depths in the Northern Andes and also, it allows a comparison with the model of crustal thickness estimated by Assumpção et al. (2013) confirming the Moho depth on both studies.

Regular physical activity and the inclusion of fruits and vegetables in dietary intake contribute to a variety of positive health outcomes and improve quality of life. With more than half of college students falling short of government guidelines for exercise and nutrition (ACHA, 2009), effective interventions targeting young adults during this transitional time are critical. Mobile phone use has become increasingly common among college students, providing an opportunity to develop intervention strategies that may be better integrated into their daily lives. Research on intervention components delivered by phone is essential for developing easily utilized, efficacious nutrition and physical activity interventions for students. Study objectives were (1) to examine the utility of a combined web-based and text-messaging intervention for physical activity and nutrition among college students, and (2) to examine the value of text message tailoring to maximize improvement in these outcomes. Students recruited from introductory psychology classes (n=151) completed measures of physical activity and nutrition at baseline and one-month follow-up. Students were randomized into one of four conditions: assessment only, web-based health behaviors feedback only, web-based feedback with standardized daily text-messages, web-based feedback with tailored daily text-messages. Primary hypotheses were that the intervention that combined web-based feedback with tailored daily text-messages would result in increased physical activity, increased fruit and vegetable intake, and greater likelihood of meeting government standards for these behaviors at follow-up compared to the assessment control condition. Regression analyses were performed with planned contrasts between experimental conditions to examine the additive impact of each intervention component on primary outcomes. Secondary analyses were conducted on additional nutrition and physical activity outcomes. Exploratory analyses were conducted to examine whether individual difference variables moderated the influence of the intervention on outcomes. Study hypotheses were not supported. No significant effect was observed for the intervention on physical activity or nutrition outcomes. These findings may suggest the need for more intensive intervention strategies to impact behavior. Future iterations should include two-way text-message communication and feedback to increase depth-of-processing, alternative tailoring approaches based on self-reported goal-systems variables, and further exploration of intervention components that may improve physical activity and nutrition among college students.

<p>The growing market of mobile services through SMS, MMS, WAP and soon also for 3G protocols, requires efficient test methods to ensure that the customers get what they are paying for and in a reasonable time. Preferably, these tests should be done automatically and come as close to real conditions as possible. It would be valuable to be able to make tests from end to end, i.e. requesting and receiving the mobile services on a real mobile phone and combine that with a system that controls and evaluates the tests. </p><p>This thesis presents a solution to how the part of an end-to-end monitoring system for mobile services that runs on a mobile phone can be designed and implemented. The phone is made to interpret commands from a control process on a remote server and turn them into mobile service requests in a proper format (e.g. SMS or MMS). When it receives the reply from a mobile service provider, it forwards the relevant result information to the control process. </p><p>The monitoring system is based on Symbian OS, an operating system developed to suit handheld devices like mobile phones. The current implementation supports tests for SMS and MMS services. </p><p>The system is to be used by mobile operators or other providers of mobile services, which want to test and monitor their services.</p>

<p>The convergence of future networks relies on the evolution of technology that enables seamless roaming abilities across non-heterogenous networks for mobile clients. This thesis presents an experimental study of a GPRS-WLAN integration scenario where the objective is to analyze various aspects of the issues related to charging, mobility, roaming and security between GPRS and WLAN networks. The mainly discussed integration scenario in this thesis is loosely coupled systems working on RADIUS platforms, which together with MobileIP and IPSec provides the mobile client with a secure and access-technology independent network access platform. </p><p>In order to accommodate GPRS client authentication for WLAN operators, there is a prominent need for the incorporation of necessary GPRS functionality into present AAA servers. RADIUS has been studied as the initial target for the implementation of a GPRS interface towards SMS-Cs and HLRs.The authentication of a mobile client is performed against a HLR/AuC in a GPRS network, either over SS7 links or through the incorporation of SIGTRAN protocols over SCTP. SIGTRANsolutions has the ability to join WLAN networks in a SS7 resource sharing model where the SS7 authentication signalling traffic is transported over IP networks to a Signalling Gateway acting as the logical interface against SS7 networks. </p><p>GPRS-WLAN accounting may be solved through direct roaming agreements between mobile operators and in such a case transport CDR’s over FTP between their billing systems. If roaming agreements does not exist, it may be viable to establish relationships between WLANs and brokers as well as mobile operators and brokers. The brokering model provides a scalable model that allows easier exchange of charging and billing information on an infrastructure based on WLAN and GPRS billing systems. Standardised transmission protocols for accounting information such as GTP’/TAP3 may be utilised in order to provide a generic billing exchange format between billing systems and operators. </p><p>Furthermore, different network architectures may have different requirements in order to accommodate GPRS clients with WLAN access. A few network architectures has been analysed, and the developed GPRS AAA Interface Daemon (GAID) has been put into context in order to present a generic GPRS-WLAN systems integration solution for WLAN operators. </p><p>The analysed solutions in this thesis give various possibilities for WLAN operators to setup wireless services for bypassing mobile clients. The implementational work provides a RADIUS platform, which can be enhanced with functionality that enables communication over any interface in the future.</p>

<p>The number of text messages sent from mobile phones, has increased dramatically over the last few years. Along with that, we are witnessing a lot of new mobile portal services currently being developed. Many of these services rely on an ability to input text efficiently. The traditional phone keypad is ambiguous because each key encodes more than one letter. At present, the most common way to deal with this problem is using a stored dictionary to guess the intended input. </p><p>This thesis presents a new text entry strategy called Qtap. Instead of using a stored dictionary to guess the intended word, this method uses probabilities of letter sequences. New features that come with Qtap are the usage of the viterbi algorithm to decode input sequences and a non-alphabetic keypad. How the strategy and the keypad used by Qtap were developed, is described throughout the thesis. </p><p>Qtap is also compared to a dictionary-based method, t9, on a non-user level. The results show Qtap is performing well in many senses. The conclusion from this is that a further development of Qtap is motivated. </p><p>A discussion of various modifications and additions to the design, that may yield a performance improvement, is also included.</p>
