Tizen은 삼성전자와 인텔(Intel), 리눅스 재단(Linux Foudation)이 공동으로 개발한 리눅스(Linux) 기반의 오픈 소스 플랫폼(Open Source Platform)이다. Tizen은 스마트폰(Smart Phone)과 태블릿 PC(Tablet PC)를 위한 운영체제이지만 GPS(Global Positioning System) 내비게이션을 포함한 자동차 인포테이먼트(In-Vehicle Infotainment) 시스템과 넷북(Netbook), 스마트 TV(Smart TV)에서도 사용될 수 있도록 개발되었다. Tizen은 안드로이드(Android)와 마찬가지로 리눅스 커널(Kernel)에서 실행할 수 있지만, 소프트웨어 프레임워크(Software Framework)는 HTML5(Hypertext Mark-up Language 5)로 설계되었다. 또한 Tizen은 HTML5 를 기반으로 다른 플랫폼에서도 쉽게 호환될 수 있는 웹 어플리케이션의 실행을 지원한다는 특징을 갖고 있다. 본 논문에서는 Tizen 웹 어플리케이션 개발의 기반이 되는 HTML5 API 와 Tizen 웹 API 를 중점적으로 살펴 본다. 그리고 이 두 가지 핵심 요소에 대한 이해를 통해 Tizen 의 향후 발전가능성을 조명한다.

We extend the previous work [J. Korean Soc. Ind. Appl. Math. 21(3) 181] to two-and three-asset equity-linked securities (ELS). In the real finance market, two-or three-asset ELS is more popular than one-asset ELS. Therefore, we need to develop mobile platform for pricing the two-and three-asset ELS. The mobile implementation of the ELS pricing will be very useful in practice.

This paper proposes a mobile image search system which uses a sensor information of smart phone, and enables running in a variety of environments, which is implemented on Android platform. The implemented system deals with a new image descriptor using combination of the visual feature (CEDD) with EXIF attributes in the target of JPEG image, and image matching scheme, which is optimized to the mobile platform. Experimental result shows that the proposed method exhibited a significant improved searching results of around 80% in precision in the large image database. Considering the performance such as processing time and precision, we think that the proposed method can be used in other application field.

Recently, metaverse has attracted great attention worldwide with the development of related technologies and the demand for on-tact systems. The ideal metaverse should constitute a virtual world more similar to the realistic society with physical interactions. However, there are many constraints when we construct a virtual world using the existing commercialized metaverse platform. In this paper, we design and implement a university campus-based metaverse which minimizes the constraints, and create a virtual environment maps very similar to the real-world using Unity engine, Photon cloud and Playfab SDK for multi-user accessible to virtual world as a personal avatar. Also, this work includes attractive interaction based on exchange between users. Lastly, we illustrate our implemented metaverse works on Android phone, and it works without difficulty in terms of performance.

This paper is about environment-based low-code and no-code execution platform and execution method that combines hybrid and native apps. In detail, this paper describes the Low-Code/No-Code execution structure that combines the advantages of hybrid and native apps. It supports the iPhone and Android phones simultaneously, supports various templates, and avoids developer-oriented development methods based on the production process of coding-free apps and the produced apps play the role of Java virtual machine (VM). The Low-Code /No-Code (LCNC) development platform is a visual integrated development environment that allows non-technical developers to drag and drop application components to develop mobile or web applications. It provides the functions to manage dependencies that are packaged into small modules such as widgets and dynamically loads when needed, to apply model-view-controller (MVC) pattern, and to handle document object model (DOM). In the Low-Code/No-Code system, the widget calls the AppOS API provided by the UCMS platform to deliver the necessary requests to AppOS. The AppOS API provides authentication/authorization, online to offline (O2O), commerce, messaging, social publishing, and vision. It includes providing the functionality of vision.

To provide convenient life, we consider the situation of using the smart phone to control smart TV and PC in home and office. In this paper, we design the interworking platform between smart TV, smart phone and PC, and implement their applications. Our smart phone application controls the smart TV and PC, where our smart TV application communicates with the smart phone and PC can be booted by the login and password information given form our smart phone application. We hope that our platform design and application implementation will be contributed to be a foundation of interworking between various smart devices in the near-future real smart life.

3D modeling and rendering technologies are getting more attention from landscape planners and architects because the virtual reality based on 3D graphic technology could give more realistic experience to landscape simulation users and boost promotional effects. The 3D landscape simulation, however, not only requires a lot of cost and time in production, but also demands efforts to distribute to consumers due to various computing environment of them. The purpose of this study is to suggest a process for developing an interactive 3D landscape simulator with low-cost, which can support multi-platform functionality in high quality through reviewing related current software and web services. We select GIMP for 2D image texturing, SketchUpfor 3D modeling, Unity for real-time rendering, and Google Earth for terrain modeling considering price and workability and apply the developed process for Windows, Web, and Android versions to test the applicability for Sangji-ri, Gosam-myeon, Gyeonggi-do, Korea.

This year, global IT companies such as Google, Apple, and Facebook launched a mobile augmented reality platform. Existing augmented reality technology required a special device such as AR glass or tango phone, but now it will be easy to experience augmented reality in general Android phone and iPhone. The mobile augmented reality game market, which has been attracting interest since the Pokemon game, is expected to become more active. In this article, we introduce augmented reality platforms technology for mobile augmented reality game and mobile augmented reality games including ETRI prototype centered on user interface.

Mobile-based software development methodology has been vigorously researched from using object-oriented development methodology and component-based development methodology previous structural developing methodology. There are two types of OS in mobile platform which are android and iOS. There is a problem that the application to be developed is developed depending on the device type. To resolve this problem, first, the system structure and design method should be managed effectively. Second, a basic design guide that can be commonly adapted to the each project is required. In this paper, we define a mobile cross platform meta model based on MDA-development methodology, focusing on reusability, portability and interoperability about non - dependent part of the mobile platform. If the proposed meta-model is applied to manage the related information and all the types of Mobile-Apps become available through independent mobile app development process, henceforward, it will be much of help establishing formulaic mobile-app developmental methodology.
