In the process of optimizing the quality of their entire product range, Sony Ericsson Mobile Communications AB have decided to review their free fall drop test equipment with the goal of increasing the precision, repeatability, and time efficiency of their drop test applications. In regard to the free fall drop test principle a robot system with management software, named Doris Drop Test System, is developed to meet these goals. As the amount of related work for this application is as minimal as the timeframes for this project, the development process is empirical and entrepreneurial with engineering skills as the governing line of work. Combining the competence from fields such as mechanics, electronics and product development, reaching the goals is successful enabling the identifying of two different drop methods – Impact Position and Drop Position. Increasing the repeatability from approximately 10% to 85% enables anyone at any time to perform the exact mobile phone drop test. By reaching a precision of up to 100%, performing free fall drop tests aiming for testing specific mobile phone parts, optimizes the development process by faster detection of mechanical weaknesses. Achieving these results in parallel with increasing the throughput by shortening the testing time, has proven the success of the Doris Drop Test System.

Several studies have highlighted the possibility that radio-frequency electromagnetic fields (RF-EMF) used in mobile phone technology could influence DNA integrity of male germ cells as well as sperm motility. Current knowledge concerning the influence of RF-EMF on male germ cells is extremely limited. In the present study the hypothesis that 900 MHz GSM radiation could induce the activation of stress response in human spermatozoa was investigated. Ejaculated, density purified, human spermatozoa from donors were exposed to 900 MHz GSM mobile phone radiation at specific absorption rate (SAR) levels of 2.0 and 5.7 W/kg and examined at various time points post exposure. Sperm motility and morphology were evaluated by computer-aided sperm analysis (CASA). The ability of RF-EMF exposed sperm to undergo the acrosome reaction was evaluated by flow cytometry. Sperm binding to the zona pellucida of human oocytes was determined by the hemi-zona (HZA) assay. Apoptotic markers, phosphatidylserine (PS) externalization, change in mitochondrial membrane potential (Δψm), reactive oxygen species (ROS) generation, caspase activation and DNA fragmentation were analysed using flow cytometry. Heat shock protein (Hsp) 27 and 70 expression and activity were analyzed using specific antibodies with flow cytometry and Western blot methods. Stress fibre stabilization (F-actin polymerization) was visualized using fluorescent dye labelled phalloidin. No effect was seen on kinematic parameters assessed at SAR 2.0 W/kg, however straight line velocity (VSL) and beat cross frequency (BCF) were significantly altered after exposure at SAR 5.7 W/kg. Sperm shrinkage (decrease in surface area) was observed at both exposure levels. RF-EMF did not influence exposed spermatozoa’s ability to undergo the acrosome reaction. A significant decrease in sperm-zona binding was observed at both exposure levels. RF radiation did not have an effect on any apoptotic markers. ROS generation increased significantly with an increase in SAR (5.7 W/kg). RF-EMF did not induce a stress response in exposed sperm (no activation of Hsp70 and 27 activity). These results cannot be ascribed to heating, as the temperature did not increase by more than 0.2 - 0.3ºC during exposure. The decrease in sperm-zona binding is the result of an alternative non-stress inducible pathway. This study should be replicated at lower SAR levels that would simulate the radiation absorption from carrying the cell phone in a pocket close to the testes. / Thesis (PhD (Reproductive Biology))--University of Pretoria, 2008. / Obstetrics and Gynaecology / unrestricted

A case study of a start-up company was performed. The study analysed the New Product Development Process at the start-up. The start-up under investigation was Zyray Wireless, a start-up in San Diego California. Zyray makes processors for the next generation of mobile phones. The research done with the particular start-up company will identify what the differences are between generally accepted best practise methods and the best practise methods implemented by a particular start-up company. The study will therefore aim to answer the following questions. How does the product development process change over the life cycle of the company? How do the best practise processes implemented in the industry differ from those implemented during the life cycle of the company under investigation. Why does the company implement best practise processes at a specific time in its life cycle and not during other times? What percentage of best practise processes are accepted and implemented by the company, why were they chosen and why were others not. Multiple types of evidence were used including participant observations, documentation and surveys. The survey taken at Zyray was compared with the industry averages. Results were also obtained at three different points in time (Concept/Seed, Product Development and Market phases). By comparing these results with the industry results it was possible to gauge the differences between the industry and Zyray Wireless in general. Zyray Wireless scored above the industry average in the following categories: continuous quality improvement, product success, project success, cycle time improvement, customer involvement questions, project selection, product strategy questions, technological leadership and product goal questions. The best practises for metrics, human resource development, documentation and change control implemented by Zyray Wireless scored at or below the industry average. The best practise results showed that the start-up focused more on strategy and engineering and less on process control. The study revealed the following important points: 1. In the initial phases the start-up’s customers were the venture funds. 2. The project selection process was informal but driven by economic criteria. 3. The company discovered that it had to choose a product strategy early on and then develop the product according to this strategy. 4. Marketing created the design concept but it also influenced the future of the company because it dictated the company’s product strategy. 5. The company followed a technology follower strategy. The technological competency was of such a high standard that a product was developed after very few iterations. 6. The start-up showed that internal documentation was limited but that external documentation to clients and manufacturers had to be of a high standard. 7. The company showed that change control was limited to the engineering function. 8. The start-up showed that over-achieving on goals set by itself and investors was of critical importance. 9. The start-up showed that process control was kept to a minimum and that it could react very quickly to changing situations. 10. The start-up showed that the establishment of a strong team is of critical importance to the success of the company. / Dissertation (MSc Technology Management)--University of Pretoria, 2007. / Graduate School of Technology Management (GSTM) / unrestricted

This research study investigates the requirements or factors that will influence the acceptance and impact of mobile phone advertising to the urban Bottom of Pyramid (BoP). The framework incorporated awareness, availability, acceptability and convenience as factors for effective mobile phone advertising. Mobile phones have received unprecedented penetration rates across all markets, including LSM 1-4. This presents companies targeting this market with an excellent advertising medium with which to communicate to consumers. Companies have begun advertising via mobile phone and this research investigates the impact of this advertising, in relation to other more established mediums, as well as the most optimal mobile phone service to be used in delivery of the advertising message. The type of advertising being sent to BoP via mobile phone advertising is analysed, along with the type of advertising the urban BoP market would like to receive and possible differences identified. The research examines the recall of advertising message across various advertising media and comparisons are drawn. The research found that all aspects of the framework were applicable. Convenience and acceptability were seen as the highest drivers for effective mobile phone advertising to the South African urban BoP. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Background: Tobacco use is one of the key problems that public health has to face. Tobacco smoking is among the main causes of morbidity and preventable mortality that can be effectively avoided. The eHealth approach uses information and communication technologies to improve the quality of health and healthcare. EHealth interventions delivered through technologies and the Internet are an effective therapeutic tool which contributes to behaviour change, including smoking cessation. This paper presents the results of continuous research on fully automated online eHealth intervention for smoking cessation. Aims: The main objective of this study was to identify the effect of the form of reminders (SMS vs. email) in eHealth smoking cessation intervention using the Endre eHealth program in the population of Czech tobacco smokers. Materials and methods: This research consists of two studies. First, a pilot study on user- acceptance of eHealth intervention was performed in a sample involving 30 respondents. This was followed by a randomized two-arm controlled study comparing the effect of a predictor in the form of eHealth intervention reminders for smoking cessation. Adult tobacco smokers were recruited based on advertising through a variety of online channels. 158 respondents were randomised for the...

The West Virginia Prescription Drug Abuse Quitline (WVPDAQ) is a resource that offers education and support to individuals and families affected by prescription drug abuse. The WVPDAQ began functioning September 11, 2008, through the use of mobile phone and laptop technology. Although some helplines and quitlines use some aspects of remote technology, most function through traditional call center and landline technology, making the WVPDAQ unique. This article describes the process evaluation of the WVPDAQ and outlines both the positive findings and challenges faced by the WVPDAQ. Lessons learned and future recommendations for remote quitline endeavors are also presented. It is hoped that the experiences and information regarding the WVPDAQ presented can provide best-practice insight for public health practitioners and evaluation personnel who are considering using alternative technologies to deliver quitline services.
