The purpose of this research is to design, develop, evaluate, and demonstrate an open source gateway and mobile application for the SmartFarm open source decision support system to improve agricultural stewardship, environmental conservation, and provide farmers with a system that they own. There are very limited options for an open source gateway for collecting data on the farm. The options available are: expensive, require professional maintenance, are not portable between systems, improvements are made only by the manufacturer, limited in customization options, difficult to operate, and data is owned by the company rather than the farmer. The gateway is designed to send data to the cloud from remote SmartFarm Data Acquisition (DAQ) nodes, collect measurement data from remote SmartFarm DAQ nodes, provide a means of wirelessly programming remote SmartFarm DAQ nodes, and a tool that provides data analysis and insight from remote SmartFarm DAQ nodes. It is evaluated to work with 900MHz radios, SmartFarm DAQ nodes, and costs $35. Its setup takes 4 steps and ~20 minutes installation time, does not require maintenance, can utilize Wi-Fi, Bluetooth, and other wireless protocols, and software can port to other systems. The gateway measured data rate of 93.4Mbit/s internet upload speed, passing a range of 252 to 1592 bytes of data from a remote node to the cloud, consumes 2.8 Watts, with a software efficiency of 25% CPU usage, a measurement efficiency of 1 message every 15 seconds, can provide data analysis with the cloud service tool, and it can wirelessly program remote DAQ nodes. The goal of the mobile app is educating farmers, academia, and community members, of farming sustainably today, and for the future. The app is used as a tool to aid people in farming sustainably, teaching agricultural stewardship, and teaching environmental conservation. The app is evaluated with adaptation of 85.1%, frequency of use at 0.12 respondents/minute, and 22 respondents said they find the SmartFarm DSS as beneficial. By developing, evaluating, and demonstrating the gateway and mobile app, the SmartFarm decision support system is a viable option for improving agricultural stewardship and retaining farmers’ ownership of their data.

This Master's degree thesis deals with a specific area of creative industries: development of mobile applications. The aim is to identify and understand the work routines of Czech iOS developers while considering the importance of design as one of the benchmarks of mobile application quality on the Apple App Store. I mainly focus on mapping work routines of selected developers and their thinking about design in the context of Apple devices and iOS platform, assuming that Apple establishes a high standard of visual and functional qualities. I am addressing an issue of application usability not only in terms of design of the user interface, but also its functioning and more aspects of application development within the ecosystem of Czech mobile app industry. The theoretical part of my thesis subjectively describes fundamental concepts from the mobile app development field and theories related to the topic. Empirical part of the study is based on qualitative interviews with 9 Czech mobile app developers and following thematic analysis. This study can serve as an interesting resource of understanding of the work of Czech mobile app developers, how they think about design and Apple as a platform or as a solid foundation for further quantitative investigation to confirm or revise my findings.

Das Betriebssystem Android bietet, aufgrund der stetig steigenden Zahl der verfügbaren mobilen Geräte auf Basis dieses System und der ebenfalls stark steigenden Zahl der Nutzer solcher Geräte, eine sehr gute Grundlage zur Entwicklung diverser mobiler Anwendungen. Es kann dabei für jeden erdenklichen Bereich des alltäglichen Lebens, vor allem Freizeit, aber auch Arbeit, eine App auf Grundlage von Android entwickelt werden. Im Bereich der mobilen Eventguides gibt es aktuell noch Entwicklungsbedarf bei den angebotenen mobilen Applikationen. So gibt es zahlreiche Anwendungen für Messen, Konferenzen oder Festivals, allerdings unterscheiden sich diese stark in ihren Funktionen und vor allem in der Darstellung von Karten und Plänen. Häufig werden solche Apps auf Grundlage eines Frameworks erstellt, welches es ermöglicht die App an verschiedene Veranstaltungen anzupassen. Die vorliegende Arbeit beschreibt die Implementierung eines Konferenzführers für die Internationale Kartographische Konferenz 2013 in Dresden. Grundlage für die Implementierung ist dabei die Betrachtung von Orientierungsmethoden und Navigationsanwendungen für Fußgänger im In- und Outdoorbereich und auf Großveranstaltungen. Hierzu werden bereits vorhandene Apps aus dem Bereich Veranstaltungen untersucht. Neben den allgemeinen Funktionen wird ein Augenmerk auf die kartographischen Funktionen solcher Apps gelegt. Im Rahmen der Arbeit wird ein Framework, auf Basis von Android, entwickelt, welches die Erstellung von mobilen Anwendungen für verschiedene Großereignisse ermöglicht. Dieses Framework wird speziell an die Internationale Kartographische Konferenz 2013 angepasst und liefert als Ergebnis eine App, die als digitaler Konferenzführer genutzt werden kann. / The Android operating system offers, due to the increasing number of available mobile devices based on this system and also the rapidly increasing number of users of such devices, a very good basis for the development of various mobile applications. It can be relevant to every conceivable area of everyday life, especially leisure, but also work to develop an app based on Android. It currently still requires development of the offered mobile applications in the area of mobile event guides. There are numerous applications for trade shows, conferences and festivals, but they differ greatly in their functions and, above all in the presentation of maps and plans. Often, such apps are created based on a framework that allows the app to adapt to different events. The present paper describes the implementation of a conference guide for the International Cartographic Conference 2013 in Dresden. Basis for the implementation is the consideration of methods of orientation and navigation applications at indoor and outdoor areas for pedestrians and on major events. To this end, existing applications from the category large events will be studied. Besides the general features a focus is placed on the cartographic features of such apps. A framework, based on Android, which allows the creation of mobile applications for various large events, will be created as part of the work. This framework is adapted to the International Cartographic Conference 2013 and delivers as a result an application that can be used as a digital conference guide.

台灣擁有豐富而多樣的自然生態資源，而物種調查將有助於維護物種之多樣性與生態平衡。然而，台灣生物多樣性高且分布廣闊，調查工作往往需耗費龐大的人力、物力、經費與時間成本。故本研究採用自願性地理資訊 (volunteered geographic information, VGI) 的方式，鼓勵社區民眾參與社區之物種調查工作。藉由社區民眾對社區當地的瞭解與使命感，有效且快速地蒐集物種調查資料。望社區民眾可經由親身參與物種調查之工作，更加瞭解及關注社區生態環境之現況，體認生態保育及生物多樣性的重要性，提升環境保育意識。 而近年來隨著行動科技的快速發展，智慧型手機與平板電腦等行動裝置日益普及。為使物種調查之工作更加快速且便利，本研究利用多數智慧型行動裝置所擁有的即時定位、無線網路及照相等功能，建置社區物種調查系統App。該App可作為物種調查之工具，並提供適時適地之物種資訊查詢服務。此外，本研究亦透過物種空間資料庫與網際網路地理資訊系統 (WebGIS) 平台之建置，提供社區物種資料分享、管理與分析等服務。 / Taiwan is abundant in ecological resources, and species investigation will contribute to preserve species diversity and ecological balance. However, due to high biodiversity and wide distribution of species in Taiwan, the traditional investigation works cost a lot of money, time, human and material resources. Therefore, this study uses the concept of volunteered geographic information (VGI) to encourage the public to collect field data and to participate in species investigation for local communities. With local knowledge and enthusiasm about the community, residents are capable of collecting species data more effectively and efficiently. On the other hand, through volunteered participation in species investigation, residents will have better understanding about the current status of ecological environment in the community. Thereby the residents can realize the importance of ecological conservation and biodiversity, and promote their awareness of environmental conservation. With the rapid development of mobile technology in recent years, mobile devices such as smartphones and tablet computers are gaining popularity. In order to make the investigation of species for communities more quickly and conveniently, this study makes use of the functions of most smart mobile devices such as real-time positioning, wireless networking, and digital camera to build a mobile App system for community-based species investigation. The mobile App system can serve as a tool for species investigation, and it also provides with location-based inquiry services timely and efficiently. In addition, Geographic Information System (GIS) is applied to manage the geodatabase, and a WebGIS platform is built to facilitate data sharing and analysis.

本研究利用字串分析之方式對行動應用程式之執行檔進行靜態分析，進以偵測行動應用程式之行為。 本研究計算行動應用程式所呼叫特定系統函式之序列，進一步比對特定可疑行為模式並判定行動應用程式是否包含其可疑行為，由於進行此研究需要考慮行動應用程式執行檔中每一個系統函式的呼叫，因此增加了大量的計算複雜度，故需要大量的運算資源來進行，為了提高運算的效率，本研究採用了Hadoop 作為分散式運算的平台來達成可延展的分析系統，進以達成分析大量行動應用程式的目的，透過建立特定的行為模式庫，本研究已分析了上千個現實使用的行動應用程式，並提供其含有潛在可疑行為的分析報告。 / This work presents a syntax analysis on the executable files of iOS apps to characterize and detect suspicious behaviors performed by the apps. The main idea is counting the appearances of call sequences in the apps which are resolved via reassembling the executable binaries. Since counting the call sequences of the app needs to consider different combinations of every function calls in the app, which significantly increases the complexity of the computing, it takes abundant computing power to bring out our analysis on massive apps on the market, to improve the performance and the effectiveness of our analysis, this work adopted a distributed computing algorithm via Hadoop framework achieving a scalable static syntax analysis which is able to process huge amount of modern apps. We learn the malicious behaviors pattern through comparing the pairs of normal and abnormal app which are identical except on certain behaviors we inserted. By matching the patterns with the call sequences we collected from the public apps, we characterized the behaviors of apps and report the suspicious behaviors carried potential security threats in the apps.

當今智慧型手機成長快速，市場潛力大，影響消費者的智慧型手機購買決策因素成為近年來值得研究的議題。但過去有關智慧型手機購買決策的研究中，大多著重在手機的作業系統或是功能層面，並未將行動應用程式(APP)及人際面的影響因素納入考量。因此，本研究以網路外部性、科技接受模型及理性行為理論為基礎，分別從智慧型手機及行動應用程式的屬性面和人際面來探討，目的為找出影響台灣地區現有智慧型手機使用者對智慧型手機再購意圖的因素，並進一步探索這些因素如何影響使用者的態度及再購意圖。本研究結果發現： 1.智慧型手機屬性面：當使用者認為智慧型手機是越有用的、越具娛樂性的，則使用者對智慧型手機的採用態度越正向；當使用者認為智慧型手機是越容易使用的，並不會直接影響其對智慧型手機的態度。 2.智慧型手機人際面：當使用者認為有越多人使用智慧型手機，則使用者對智慧型手機的購買意圖越正向；而無論使用者認為其家人、伴侶、好友、同學或同事支不支持其使用智慧型手機，都不會影響其對智慧型手機的購買意圖。 3.行動應用程式屬性面：當使用者認為在短時間內行動應用程式的數量成長的越快速，則其對智慧型手機的態度會越正面；而無論使用者認為APP數量、種類的多少、價格是否可被接受以及APP的設計品質完不完善等，都不會直接影響使用者對智慧型手機的態度。 4.行動應用程式人際面：當使用者認為其家人、伴侶、好友、同學或同事越支持其使用行動應用程式時，使用者對智慧型手機的態度會越正向。

Finalmente, Quillqara demostró ser un proyecto innovador y con posibles resultados positivos a futuro a pesar de la coyuntura. / In the present project, the research for the validation of the business model of an application that allows buying and selling of second-hand books will be developed. The business idea is aimed at two customer segments: people who want to sell unused books and people who want to buy second-hand books in good condition. This digital platform has books of the academic, literature and general culture genres. For the project research, experiments were carried out that gave us information about the needs and preferences of both users, as well as real data that allowed us to project our sales and define our expenses. Within these experiments, each part of the proposed business model and the interaction between the user and the prototype of the application to be developed were validated. In order to get closer to our customer segments, we developed a digital marketing plan for our social networks and this allowed us to generate a relationship with our customers. In this sense, the data collected in the different experiments was the necessary basis to carry out the initial cost structure, which was then deepened into a complete cash flow for our business idea projected to 3 years. In addition to this, the analysis and calculation of the financing that the project would receive from the investor and us ,the founders, was carried out. Finally, Quillqara proved to be an innovative project with possible positive results in the future despite the situation. / Trabajo de investigación
