TURKU TAKING STEPS TOWARDS FUTURE - technology supports physical activity

Physical activity (PA) is an important field of healthcare research internationally and within Finland. As technology devices and services penetrate deeper levels within society, the need for studying the usefulness for PA turns vital. We started this research work by reviewing literature consisting of two hundred research journals, all of which have found technology to significantly improve an individual’s ability to get motivation and achieve officially recommended levels of physical activity, like the 10000 steps a day, being tracked with the help of pedometers. Physical activity recommendations require sustained encouragement, consistent performance in order to achieve the long term benefits. We surveyed within the city of Turku, how the motivation levels and thirty three other criterions encompassing technology awareness, adoption and usage attitudes are impacted. Our aim was to know the factors responsible for achieving consistent growth in activity levels within the individuals and focus groups, as well as to determine the causes of failures and for collecting user experience feedback. The survey results were quite interesting and contain impeccable information for this field. While the focus groups confirmed the theory established by past studies within our literature review, it also establishes our research propositions that ict tools and services have provided and can further add higher benefits and value to individuals in tracking and maintain their activity levels consistently for longer time durations. This thesis includes two new models which dictate technology and physical activity adoption patterns based on four easy to evaluate criterions, thereby helping the healthcare providers to recommend improvements and address issues with an easy rule based approach. This research work provides vital clues on technology based healthcare objectives and achievement of standard PA recommendations by people within Turku and nearby regions.

Bridging the digital divide in developing countries: The role of mobile technology in bridging the digital divide

This thesis investigates how mobile technology usage could help to bring Information and communication technologies (ICT) to the people in developing countries. Some people in developing countries have access to use ICT while other people do not have such opportunity. This digital divide among people is present in many developing countries where computers and the Internet are difficult to access. The Internet provides information that can increase productivity and enable markets to function more efficiently. The Internet reduces information travel time and provides more efficient ways for firms and workers to operate. ICT and the Internet can provide opportunities for economic growth and productivity in developing countries. This indicates that it is very important to bridge the digital divide and increase Internet connections in developing countries. The purpose of this thesis is to investigate how can mobile technology and mobile services help to bridge the digital divide in developing countries. Theoretical background of this thesis consists of a collection of articles and reports. Theoretical material was gathered by going through literature on the digital divide, mobile technology and mobile application development. The empirical research was conducted by sending a questionnaire by email to a selection of application developers located in developing countries. The questionnaire’s purpose was to gather qualitative information concerning mobile application development in developing countries. This thesis main result suggests that mobile phones and mobile technology usage can help to bridge the digital divide in developing countries. This study finds that mobile technology provides one of the best tools that can help to bridge the digital divide in developing countries. Mobile technology can bring affordable ICT to people who do not have access to use computers. Smartphones can provide Internet connection, mobile services and mobile applications to a rapidly growing number of mobile phone users in developing countries. New low-cost smartphones empower people in developing countries to have access to information through the Internet. Mobile technology has the potential to help to bridge the digital divide in developing countries where a vast amount of people own mobile phones.

Improving the usability of extruded wood-plastic composites by using modification technology

Using cellulosic reinforcement to produce plastic composites is a globally growing trend. One of such materials are wood-plastic composites, which are an extensively studied group of materials for which the global industry is looking for new applications. Issues such as bondability, durability and fire resistance still require development to improve the usability of the wood-plastic composite material. Improvement of the usability of wood-plastic composites is studied in this thesis through the effects of using selected modification technology in wood and plastic industry. The applied modification methods are surface by mechanical abrasion and plasma, chemical impregnation of wood flour, and structural modification by the co-extrusion process. The study shows that the properties of WPC can be influenced by the selected modification methods. The selected methods are also found to be able to result as improvement in the properties of the material. The may also affect other than just the targeted properties of the end-product, either in a positive or a negative manner. Therefore modification as performance improvement should be considered as a caseby- case study. Introducing WPC materials for new applications can be done by using modification technology. Structuralmodification can possibly be used to reduce material costs of the modified WPC material.

Learning information technology business in a changing industry landscape. Introducing Team Entrepreneurship in Renewing Bachelor Education in Renewing Bachelor Education in Information

Speed, uncertainty and complexity are increasing in the business world all the time. When knowledge and skills become quickly irrelevant, new challenges are set for information technology (IT) education. Meta-learning skills – learning how to learn rapidly - and innovation skills have become more essential than single technologies or other specific issues. The drastic changes in the information and communications technology (ICT) sector have caused a need to reconsider how IT Bachelor education in Universities of Applied Sciences should be organized and employed to cope with the change. The objective of the study was to evaluate how a new approach to IT Bachelor education, the ICT entrepreneurship study path (ICT-ESP) fits IT Bachelor education in a Finnish University of Applied Sciences. This kind of educational arrangement has not been employed elsewhere in the context of IT Bachelor education. The study presents the results of a four-year period during which IT Bachelor education was renewed in a Finnish University of Applied Sciences. The learning environment was organized into an ICT-ESP based on Nonaka’s knowledge theory and Kolb’s experiental learning. The IT students who studied in the ICT-ESP established a cooperative and learned ICT by running their cooperative at the University of Applied Sciences. The students (called team entrepreneurs) studied by reading theory in books and other sources of explicit information, doing projects for their customers, and reflecting in training sessions on what was learnt by doing and by studying the literature. Action research was used as the research strategy in this study. Empirical data was collected via theme-based interviews, direct observation, and participative observation. Grounded theory method was utilized in the data analysis and the theoretical sampling was used to guide the data collection. The context of the University of Applied Sciences provided a good basis for fostering team entrepreneurship. However, the results showed that the employment of the ICT-ESP did not fit into the IT Bachelor education well enough. The ICT-ESP was cognitively too tough for the team entrepreneurs because they had two different set of rules to follow in their studies. The conventional courses engaged lot of energy which should have been spent for professional development in the ICT-ESP. The amount of competencies needed in the ICT-ESP for professional development was greater than those needed for any other ways of studying. The team entrepreneurs needed to develop skills in ICT, leadership and self-leadership, team development and entrepreneurship skills. The entrepreneurship skills included skills on marketing and sales, brand development, productization, and business administration. Considering the three-year time the team entrepreneurs spent in the ICT-ESP, the challenges were remarkable. Changes to the organization of IT Bachelor education are also suggested in the study. At first, it should be admitted that the ICT-ESP produces IT Bachelors with a different set of competencies compared to the conventional way of educating IT Bachelors. Secondly, the number of courses on general topics in mathematics, physics, and languages for team entrepreneurs studying in the ICTESP should be reconsidered and the conventional course-based teaching of the topics should be reorganized to support the team coaching process of the team entrepreneurs with their practiceoriented projects. Third, the upcoming team entrepreneurs should be equipped with relevant information about the ICT-ESP and what it would require in practice to study as a team entrepreneur. Finally, the upcoming team entrepreneurs should be carefully selected before they start in the ICT-ESP to have a possibility to eliminate solo players and those who have a too romantic view of being a team entrepreneur. The results gained in the study provided answers to the original research questions and the objectives of the study were met. Even though the IT degree programme was terminated during the research process, the amount of qualitative data gathered made it possible to justify the interpretations done.

In this review, we attempt to provide an overview of the principles of cDNA microarray technology, the practical concerns of the analytical processing of the data obtained, the correlation of this methodology with other data analysis methods such as immunohistochemistry in tissue microarrays, and the cDNA microarray application in distinct areas of the basic and clinical sciences.

Invoice process analysis and development. Case: Power and automation technology company

This master’s thesis studies the case company’s current purchase invoice process and the challenges that are related to it. Like most of other master’s thesis this study consists of both theoretical- and empirical parts. The purpose of this work is to combine theoretical and empirical parts together so that the theoretical part brings value to the empirical case study. The case company’s main business is frequency converters for both low voltage AC & DC drives and medium voltage AC Drives which are used across all industries and applications. The main focus of this study is on the current invoice process modelling. When modelling the existing process with discipline and care, current challenges can be understood better. Empirical study relays heavily on interviews and existing, yet fragmented, data. This, along with own calculations and analysis, creates the foundation for the empirical part of this master’s thesis.

Industrialized cashew juices: variation of ascorbic acid and other physicochemical parameters

Commercial cashew apple juice is widely accepted in the Brazilian market. Cashew apple has high content of ascorbic acid, an important nutrient to human beings. Ascorbic acid content in food can be affected by processing and storage conditions. Commercial cashew apple juice samples, ready-to-drink and concentrated, were analyzed. The ascorbic acid content, total titratable acidity, total soluble solids, and pH of the juices were determined during storage at 4 °C after the containers were opened. The ascorbic acid content presented a great variability among the samples analyzed ranging from 37.3 to 46.3 mg.100 mL-1 in ready-to-drink juices and from 75.7 to 152 mg.100 mL-1 in concentrated juices. The storage of commercial cashew apple juices for 48 hours at 4 °C resulted in ascorbic acid losses of up to 8.8% for concentrated and 6.4% for ready-to-drink juices. The other parameters remained stable during storage. The results of this study point to the importance of considering ascorbic acid losses in commercial cashew apple juices which occurs after opening but before the expiration date expires.

Quinoa (Chenopodium quinoa, Willd.) as a source of dietary fiber and other functional components

Four varieties of an Andean indigenous crop, quinoa (Chenopodium quinoa Willd.), were evaluated as a source of dietary fiber, phenolic compounds and antioxidant activity. The crops were processed by extrusion-cooking and the final products were analyzed to determine the dietary fiber, total polyphenols, radical scavenging activity, and in vitro digestibility of starch and protein. There were no significant differences in the contents of total dietary fiber between varieties of quinoa. In all cases, the contents of total and insoluble dietary fiber decreased during the extrusion process. At the same time, the content of soluble dietary fiber increased. The content of total phenolic compounds and the radical scavenging activity increased during the extrusion process in the case of all 4 varieties. There were significant differences between the varieties and the content of total polyphenols. The in vitro protein digestibility of quinoa varieties was between 76.3 and 80.5% and the in vitro starch digestibility was between 65.1 and 68.7%. Our study demonstrates that quinoa can be considered a good source of dietary fiber, polyphenols and other antioxidant compounds and that extrusion improves the nutritional value.

The role of nuclear and other conventional power plants in the flexible energy system

This thesis reviews the role of nuclear and conventional power plants in the future energy system. The review is done by utilizing freely accesible publications in addition to generating load duration and ramping curves for Nordic energy system. As the aim of the future energy system is to reduce GHG-emissions and avoid further global warming, the need for flexible power generation increases with the increased share of intermittent renewables. The goal of this thesis is to offer extensive understanding of possibilities and restrictions that nuclear power and conventional power plants have regarding flexible and sustainable generation. As a conclusion, nuclear power is the only technology that is able to provide large scale GHG-free power output variations with good ramping values. Most of the currently operating plants are able to take part in load following as the requirement to do so is already required to be included in the plant design. Load duration and ramping curves produced prove that nuclear power is able to cover most of the annual generation variation and ramping needs in the Nordic energy system. From the conventional power generation methods, only biomass combustion can be considered GHG-free because biomass is considered carbon neutral. CFB combusted biomass has good load follow capabilities in good ramping and turndown ratios. All the other conventional power generation technologies generate GHG-emissions and therefore the use of these technologies should be reduced.

Metal music as critical dystopia : humans, technology and the future in 1990s science fiction metal

Metal Music as Critical Dystopia: Humans, Technology and the Future in 1990s Science Fiction Metal seeks to demonstrate that the dystopian elements in metal music are not merely or necessarily a sonic celebration of disaster. Rather, metal music's fascination with dystopian imagery is often critical in intent, borrowing themes and imagery from other literary and cinematic traditions in an effort to express a form of social commentary. The artists and musical works examined in this thesis maintain strong ties with the science fiction genre, in particular, and tum to science fiction conventions in order to examine the long-term implications of humanity's complex relationship with advanced technology. Situating metal's engagements with science fiction in relation to a broader practice of blending science fiction and popular music and to the technophobic tradition in writing and film, this thesis analyzes the works of two science fiction metal bands, VOlvod and Fear Factory, and provides close readings of four futuristic albums from the mid to late 1990s that address humanity's relationship with advanced technology in musical and visual imagery as well as lyrics. These recorded texts, described here as cyber metal for their preoccupation with technology in subject matter and in sound, represent prime examples of the critical dystopia in metal music. While these albums identify contemporary problems as the root bf devastation yet to come, their musical narratives leave room for the possibility of hope , allowing for the chance that dystopia is not our inevitable future.

Introduction to engineering : a case study of an interdisciplinary course in Mathematics, Science and Technology

This thesis research was a qualitative case study of a single class of Interdisciplinary Studies: Introduction to Engineering taught in a secondary school. The study endeavoured to explore students' experiences in and perceptions of the course, and to investigate the viability of engineering as an interdisciplinary theme at the secondary school level. Data were collected in the form of student questionnaires, the researcher's observations and reflections, and artefacts representative of students' work. Data analysis was performed by coding textual data and classifying text segments into common themes. The themes that emerged from the data were aligned with facets of interdisciplinary study, including making connections, project-based learning, and student engagement and affective outcomes. The findings of the study showed that students were positive about their experiences in the course, and enjoyed its project-driven nature. Content from mathematics, physics, and technological design was easily integrated under the umbrella of engineering. Students felt that the opportunity to develop problem solving and teamwork skills were two of the most important aspects of the course and could be relevant not only for engineering, but for other disciplines or their day-to-day lives after secondary school. The study concluded that engineering education in secondary school can be a worthwhile experience for a variety of students and not just those intending postsecondary study in engineering. This has implications for the inclusion of engineering in the secondary school curriculum and can inform the practice of curriculum planners at the school, school board, and provincial levels. Suggested directions for further research include classroom-based action research in the areas of technological education, engineering education in secondary school, and interdisciplinary education.

Intellectual Property Protection For Plant Derived Vaccine Technology: Here They Come Are We Ready or Not ?

Il existe une nouvelle catégorie de technologie, les vaccins dérivés de plantes («VDPs»), qui englobe des produits qui ont un grand potentiel pour l’amélioration de la santé à l’échelle globale. Bien qu’ils ne soient pas encore disponibles pour le public, le développement des VDPs a progressé de façon telle qu’ils devraient être prêts à être mis en marché et distribués sous peu. Ainsi, c’est le moment idéal pour lancer un débat sur la meilleure façon de protéger cette nouvelle catégorie de technologie. Vu leur nature, les VDPs ne se qualifient pas parfaitement pour aucune forme de protection de propriété intellectuelle. En effet, un VDP est à la fois une variété de plante, une biotechnologie, un médicament et un produit qui vise spécifiquement les besoins de pays en voie de développement. Chacune de ces caractéristiques soulève ses propres problématiques en ce qui a trait à la propriété intellectuelle. C’est pourquoi il appert difficile d’identifier la forme de protection la plus adéquate et appropriée pour les VDPs. Cet article traite de la nature d’un VDP, des différentes catégories dans lesquelles il pourrait être classé, des différents types de systèmes de protection de propriété intellectuelle auxquels il pourrait être éligible ainsi que des problèmes qui pourraient être soulevés par tous ces éléments. Ces discussions visent à mettre l’accent sur le fait que nous avons affaire à une toute nouvelle catégorie d’innovation technologique. L’auteure est donc d’avis qu’une approche proactive est nécessaire pour discuter d’un système de protection de propriété intellectuelle en relation avec les VDPs. En ce moment, c’est l’inventeur qui choisi comment il protègera son invention. Les moyens employés par ce dernier pourraient être subséquemment modifiés ou annulés par une décision judiciaire mais comme plusieurs autres inventeurs d’une même catégorie de technologie auront probablement déjà adopté une stratégie de protection similaire, ce type de mesures judiciaire, très tard dans le processus, pourra avoir des résultats néfastes sur les détenteurs de droits. Le développement de lignes directrices d’entrée de jeu, avec l’aide d’un panel d’experts de préférence, peut contribuer à éviter les situations de confusion qui ont déjà été vécues avec l’application d’autres nouvelles technologies et qui devraient servir de leçon pour l’encadrement des VDPs.

Studying the cytomechanic aspects of pollen tube growth behavior using Lab-On-Chip technology

L'élongation cellulaire de cellules cultivant bout comme hyphae fongueux, inculquez hairs, des tubes de pollen et des neurones, est limité au bout de la cellule, qui permet à ces cellules d'envahir l'encerclement substrate et atteindre une cible. Les cellules cultivant bout d'équipement sont entourées par le mur polysaccharide rigide qui régule la croissance et l'élongation de ces cellules, un mécanisme qui est radicalement différent des cellules non-walled. La compréhension du règlement du mur de cellule les propriétés mécaniques dans le contrôle de la croissance et du fonctionnement cellulaire du tube de pollen, une cellule rapidement grandissante d'équipement, est le but de ce projet. Le tube de pollen porte des spermatozoïdes du grain de pollen à l'ovule pour la fertilisation et sur sa voie du stigmate vers l'ovaire le tube de pollen envahit physiquement le stylar le tissu émettant de la fleur. Pour atteindre sa cible il doit aussi changer sa direction de croissance les temps multiples. Pour évaluer la conduite de tubes de pollen grandissants, un dans le système expérimental vitro basé sur la technologie de laboratoire-sur-fragment (LOC) et MEMS (les systèmes micro-électromécaniques) ont été conçus. En utilisant ces artifices nous avons mesuré une variété de propriétés physiques caractérisant le tube de pollen de Camélia, comme la croissance la croissance accélérée, envahissante et dilatant la force. Dans une des organisations expérimentales les tubes ont été exposés aux ouvertures en forme de fente faites de l'élastique PDMS (polydimethylsiloxane) la matière nous permettant de mesurer la force qu'un tube de pollen exerce pour dilater la croissance substrate. Cette capacité d'invasion est essentielle pour les tubes de pollen de leur permettre d'entrer dans les espaces intercellulaires étroits dans les tissus pistillar. Dans d'autres essais nous avons utilisé l'organisation microfluidic pour évaluer si les tubes de pollen peuvent s'allonger dans l'air et s'ils ont une mémoire directionnelle. Une des applications auxquelles le laboratoire s'intéresse est l'enquête de processus intracellulaires comme le mouvement d'organelles fluorescemment étiqueté ou les macromolécules pendant que les tubes de pollen grandissent dans les artifices LOC. Pour prouver que les artifices sont compatibles avec la microscopie optique à haute résolution et la microscopie de fluorescence, j'ai utilisé le colorant de styryl FM1-43 pour étiqueter le système endomembrane de tubes de pollen de cognassier du Japon de Camélia. L'observation du cône de vésicule, une agrégation d'endocytic et les vésicules exocytic dans le cytoplasme apical du bout de tube de pollen, n'a pas posé de problèmes des tubes de pollen trouvés dans le LOC. Pourtant, le colorant particulier en question a adhéré au sidewalls du LOC microfluidic le réseau, en faisant l'observation de tubes de pollen près du difficile sidewalls à cause du signal extrêmement fluorescent du mur. Cette propriété du colorant pourrait être utile de refléter la géométrie de réseau en faisant marcher dans le mode de fluorescence.

Applying 3D modelling technology to traditional craftwork : rapid prototyping in artisanal jewellery making and its impact on the perceived value of jewellery

Depuis la révolution industrielle, l’évolution de la technologie bouleverse le monde de la fabrication. Aujourd'hui, de nouvelles technologies telles que le prototypage rapide font une percée dans des domaines comme celui de la fabrication de bijoux, appartenant jadis à l'artisanat et en bouscule les traditions par l'introduction de méthodes plus rapides et plus faciles. Cette recherche vise à répondre aux deux questions suivantes : - ‘En quoi le prototypage rapide influence-t-il la pratique de fabrication de bijoux?’ - ‘En quoi influence-t-il de potentiels acheteurs dans leur appréciation du bijou?’ L' approche consiste en une collecte de données faite au cours de trois entretiens avec différents bijoutiers et une rencontre de deux groupes de discussion composés de consommateurs potentiels. Les résultats ont révélé l’utilité du prototypage rapide pour surmonter un certain nombre d'obstacles inhérents au fait-main, tel que dans sa géométrie, sa commercialisation, et sa finesse de détails. Cependant, il se crée une distance entre la main du bijoutier et l'objet, changeant ainsi la nature de la pratique. Cette technologie est perçue comme un moyen moins authentique car la machine rappelle la production de masse et la possibilité de reproduction en série détruit la notion d’unicité du bijou, en réduisant ainsi sa charge émotionnelle. Cette recherche propose une meilleure compréhension de l'utilisation du prototypage rapide et de ses conséquences dans la fabrication de bijoux. Peut-être ouvrira-t-elle la voie à une recherche visant un meilleur mariage entre cette technique et les méthodes traditionnelles.
