최근 스마트폰과 같은 다양한 애플리케이션을 사용할 수 있는 모바일폰의 유행에 힘입어 모바일 애플리케이션 수요가 폭발적으로 증가하고 있고, 이에 따라 모바일 애플리케이션에서에 품질의 중요성도 점차 커지고 있다. 하지만 모바일 애플리케이션은 다양한 플랫폼이나 모바일폰의 제약사항에 따라 플랫폼이나 디바이스 장치 간의 호환성이 떨어지는 특성을 가짐으로써, 다른 플랫폼에서 애플리케이션을 재사용하기 위해서 해당 플랫폼이나 모바일폰의 제약사항에 따라 다시 개발해야하는 제약을 가진다. 따라서, 본 논문에서는 모바일 애플리케이션을 타 플랫폼에서 재사용하기 위해, 이식할 때 발생할 수 있는 문제를 확인하고 그에 따른 기존 모바일 애플리케이션에 이식의 편이를 확인할 수 있는 이식성 품질 평가 기법을 제안한다. 이에 따라 제안한 이식성의 편이를 나타내는 이식성 점수를 확인함으로써 모바일 애플리케이션이 타 플랫폼에 이식될 때 발생할 수 있는 문제점을 확인하고 이에 따른 재개발 가능 여부와 노력 정도를 확인할 수 있는 근거가 될 수 있을 것으로 기대된다. 또한 이를 모바일 애플리케이션의 설계부터 고려한다면 다양한 모바일 플랫폼에 좀 더 쉽게 이식할 수 있는 품질 좋은 모바일 애플리케이션을 개발할 수 있는 방법이 될 수 있을 것으로 기대된다.

Objectives: The objective of this study was to develop mobile phone application for image-based dietary assessment and evaluate satisfaction regarding respondent's use of the mobile phone application. Methods: We developed a mobile phone application to assess dietary intakes using 24 hour dietary recall. After initial development, application was reviewed by ten adults and revised based on their comments. We recruited 192 volunteers (92 males, 100 females) to use the mobile phone application and to respond to a satisfaction survey. Participants were instructed to use the mobile phone application with fiducial marker five centimeter in width, length and two centimeter height at each eating occasion during designated 4 days, capturing $45^{\circ}$ angle and $90^{\circ}$ angle images of all food and beverage items before and after consumption. After using the mobile phone application for 4 days, participants were asked to complete an online questionnaire on the satisfaction of the mobile phone app. User satisfaction items composed of 12 questions of application user interface, 8 questions of emotional response, 9 questions of eating behavior in 5 likert scale. Participants were also asked to provide additional open-ended comments on the use of mobile phone application. Statistical analysis was performed by using the SPSS 23.0 (Statistical Package for the Social Science). Results: The average user interface score was $2.82{\pm}1.08$, which was close to the 'normal' response. Responses for emotion and eating behavior also were borderline to the 'normal'. Conclusions: This study found that the mobile phone application using 24-hour recall was acceptable to be used to assess dietary intakes for several days. However, there should be a need for such technology to be user-oriented instead of researcher-oriented. Easy and cost-effective new technology is needed for estimating the amounts of food eaten automatically when the photos are taken.

The proliferation of mobile applications and the unique characteristics of the mobile environment have attracted significant research interest in understanding customers' purchasing behaviors in mobile commerce. In this study, we extend customer value theory by combining the predictors of product performance with customer value framework to investigate how in-store information creates value for customers and influences mobile application downloads. Using a data set collected from the Google Application Store, we find that customers value both text and non-text information when they make downloading decisions. We apply latent semantic analysis techniques to analyze customer reviews and product descriptions in the mobile application store and determine the embedded valuable information. Results show that, for mobile applications, price, number of raters, and helpful information in customer reviews and product descriptions significantly affect the number of downloads. Conversely, average rating does not work in the mobile environment. This study contributes to the literature by revealing the role of in-store information in mobile application downloads and by providing application developers with useful guidance about increasing application downloads by improving in-store information management.

Mobility and cloud platform have become the dominant paradigm to develop web services dealing with huge and diverse digital contents for scientific solution or engineering application. These two trends are technically combined into mobile cloud computing environment taking beneficial points from each. The intention of this study is to design and implement a mobile cloud application for remotely sensed image fusion for the further practical geo-based mobile services. In this implementation, the system architecture consists of two parts: mobile web client and cloud application server. Mobile web client is for user interface regarding image fusion application processing and image visualization and for mobile web service of data listing and browsing. Cloud application server works on OpenStack, open source cloud platform. In this part, three server instances are generated as web server instance, tiling server instance, and fusion server instance. With metadata browsing of the processing data, image fusion by Bayesian approach is performed using functions within Orfeo Toolbox (OTB), open source remote sensing library. In addition, similarity of fused images with respect to input image set is estimated by histogram distance metrics. This result can be used as the reference criterion for user parameter choice on Bayesian image fusion. It is thought that the implementation strategy for mobile cloud application based on full open sources provides good points for a mobile service supporting specific remote sensing functions, besides image fusion schemes, by user demands to expand remote sensing application fields.
