모바일 디바이스는 유연한 이동성을 제공하는 대신에 제한된 자원을 가지고 있는 휴대용 장치로서, 어플리케이션 구동을 가능하게 하는 새로운 클라이언트 단말기로 빠른 속도로 보급되고 있다. 대표적인 모바일 디바이스로는 iPhone, 안드로이든 폰이 있다. 현재 이러한 모바일 디바이스에는 엔터테인먼튼 관련 어플리케이션이 널리 사용되고 있지만, 앞으로 모바일 디바이스의 성장 및 네트워크 기술에 따라 다소 복잡한 어플리케이션을 필요로 하게 된다. 그러나, 모바일 디바이스에서 실행될 수 있는 어플리케이션의 복잡도에 제약이 발생하여 놓은 복잡도의 어플리케이션은 실행이 힘들다. GUI 어플리케이션에서 데이터와 그것을 표현하는 부분을 나누어 설계하는 MVC (Model-View-Control) 아키텍쳐는 어플리케이션을 설계하는데 일반적으로 많이 사용되고 있지만, 이는 모바일 어플리케이션의 특징을 반영하지는 못한다. 그러므로, 본 논문에서는 자원 사용의 최적화를 고려한 서비스 기반 모바일 어플리케이션을 설계하기 위하여 기존의 MVC 아키텍처를 보완/확장한다. 본 논문에서 제안하는 MVC 아키텍쳐는 어플리케이션 특성에 맞춰 모바일 어플리케이션의 특성들을 극복하여 모바일 디바이스의 한계점을 극복하는 동시에 고성능을 보장하는 모바일 어플리케이션을 개발하는데 적용할 수 있다.

최근 모바일과 관련된 주요 플랫폼의 등장과 모바일 시장의 지속적인 성장 따라, 더 이상 기존 기업도 모바일 어플리케이션 개발은 선택의 문제가 아님을 인식하여 지속적인 투자를 하고 있다. 하지만 모바일 어플리케이션 시장의 급성장에 비해 품질평가 기준이 명확하지 않아 검증되지 않은 모바일 어플리케이션이 유포되고 있는 것이 현실이다. 이 논문에서는 국제표준인 ISO/IEC 9126-2의 품질 메트릭에 기반하여 다양한 모바일 디바이스 환경에서 모바일 어플리케이션의 성능에 대한 품질평가 방안을 제시하고 있다.

Mobile devices with Android OS and iOS have been emerged as mobile computing devices where various software applications are deployed. Furthermore, they are anticipated to be used not only for traditional personal computing but also for enterprise computing. However, such mobile devices have their intrinsic characteristics such as limited resources and flexible network capabilities, which are not revealed in traditional computers. Hence, there is high demand for methods to develop mobile applications with reflecting their intrinsic characteristics. Since those characteristics belong to non-functional requirements, they should be reflected in architecture design while designing mobile applications. To design architecture, the architecture drivers that are architecture non-functional requirements are decided from mobile application characteristics. Conventional architecture design methods do not consider those characteristics so that the methods cannot be straightforwardly applied to mobile applications. In this paper, to efficiently develop mobile applications reflecting those characteristics, we propose a set of architecture patterns and define a guideline to apply those patterns. First, we define the characteristics of mobile applications distinguished and derive architectural drivers from them. Then, we propose architecture patterns in terms of static and dynamic views and define an architectural guideline to apply the patterns to designing architecture for mobile application. And, we perform case studies to verify the applicability of proposed patterns. Finally, we assess the proposed architecture patterns by proving how the patterns can fulfill identified architecture drivers and by comparing our approach with previous works.

MDD is suitable to satisfy constraints of development of mobile applications. So, there are various studies about applying MDD to the developments of mobile application but systematic development methods about UML profile for PIM/PSM of mobile applications and model transformation techniques are needed. This paper suggests that a development technique about UML profile for PIM/PSM of mobile applications and a model transformation techniques with the profiles. We classify stereotypes by the characteristics of mobile application to compose profiles and suggest development guidelines of profiles for PIM/PSM. On the suggested model transformation process, the PIM with the profiles is transformed to the intial PSM with the mapping rules and the PSM is transformed to the refined PSM with templates which reflected detailed information of a mobile platform. We developed a location based service mobile application with the suggested techniques on the Android platform and compared with other techniques to validate usefulness of the suggested techniques.

모바일 어플리케이션 개발자들은 센서를 활용하여 사용자를 위한 맞춤화 서비스를 제공하고 있다. 센서를 활용한 어플리케이션은 다른 소프트웨어와 마찬가지로 더욱 높은 품질을 위해 테스트를 필요로 한다. 그러나 기존의 모바일 어플리케이션을 위한 테스트 도구들은 센서에 대한 접근성, 센서 데이터 입력, 전력 소모에 대한 비고려 등의 문제를 갖고 있어, 동적 테스트를 수행하는데 사용하기에는 한계를 지니고 있다. 물론, 이러한 문제를 해결하기 위해 여러 연구들이 진행되어 왔지만 기존의 연구들은 일부의 특성만을 반영한 테스트 도구를 개발하였거나, 기법만 개발하였다. 따라서 본 논문에서는 이러한 특성들을 통합적으로 반영한 동적 테스트 도구를 개발하기 위해 센서를 활용한 어플리케이션의 특성을 도출하고, 이를 이용하여 기존의 동적 테스트 도구들의 한계점을 분석하였다. 그 후, 이를 기반으로 하여 동적 테스트 도구의 요구사항을 도출하였다. 그 결과, 총 3개의 특성과 5개의 한계점 그리고 6개의 요구사항을 도출하였다. 향후 본 논문은 센서를 활용한 어플리케이션을 위한 동적 테스트 도구의 개발에 기초가 될 것이다.

One of the most important parts of the user experience in mobile device interaction is navigation design. Navigation design plays a key role in enabling users to perform their desired functions and to access the information and content they need by mobile applications. In this process, differences in cultural characteristics and backgrounds of users may affect the navigation design, and thus the user experience may represent a significant difference. This study compared the navigation design of popular mobile shopping applications in China and the United States to examine the differences and analyzed the reasons. Based on this comparison, we proposed that the Chinese preferred rich information, colorful images and various menu styles, while Americans preferred simple designs, layouts and limited types of menu. In addition, two types of mobile shopping application navigation design schemes reflecting cultural characteristics were evaluated to examine the difference of Chinese and American users' preference, and the validity of our study was verified based on the results.

This study explores unified service experience to boost O2O services. Previous studies on service management and marketing only focused on customer experience in offline stores, while prior works on information systems looked only at the experience of services in mobile applications. In this vein, this study took into accounts the characteristics of offline stores and the benefits of their mobile applications. Moreover, the final dependent variable was share of wallet to measure customer's expenditure within the category. The theoretical model was tested based on 219 consumers who frequently visit Starbucks and use its mobile application. PLS method was applied to analysis the research model and hypotheses. The analysis results showed that customer satisfaction about offline store is not significantly related to share of wallet, while satisfaction about mobile application plays a significant role in enhancing share of wallet. Hedonic and social benefits were found to have significant effects on satisfaction about mobile application. The analysis results help establish service marketing and strategies to enhance the unified customer experience of O2O service.

Mobile Devices, which are developed with the fast growing of the Internet, have flexible internet accessibility and can access the network anywere so that they can execute software applications. However, it is very challenging to deploy highly complex applications on mobile devices since they have limited resources. To overcome the limitation, researches on applying a concept of services to mobile applications have been proposed. Android is one of the popular mobile platforms and is designed to effectively execute mobile applications on the mobile devices having limited resources. Since service-based Android applications, which adopt a concept of services and Android platform, invoke remote services and are built with Android-specific components, they are much different from traditional software applications. Consequently, it is not straightforward to apply object-oriented (OO) analysis and design methods to developing service-based Android applications, although they have been frequently applied to developing traditional applications. In this paper, we present a process to develop service-based Android mobile applications, which extends a traditional OO development process. First, we raise design issues to be considered in developing service-based Android applications. Then, to solve the issues, we present detailed guidelines for essential phases of OO-based development process that are customized to service-based Android applications. Finally, to show applicability of the process, we perform a case study. The proposed design process is effectively utilized as a set of guidelines to develop service-based Android applications more systematically and effectively.
