멀티미디어 디지털 기기의 발전은 Mobile Phone의 사용량 증가로 대두되고 있으며 그에 따른 문제를 해결하는 일도 시급한 상황이다. Mobile Phone 사용 중 작동이 멈춘다거나 하는 문제는 그 사용자수에 비례하여 발생 빈도나 위험성이 높아질 수밖에 없다. 이런 문제가 생기지 않도록 사전에 철저한 테스트를 해보고 시행착오를 겪어봐야 완벽한 제품으로 시중에 내놓을 수 있게 되는 것이다. 기존의 하드웨어와 연결해서 사용 하던 디버거와는 다르게 Remote Debugger는 이러한 문제점을 툴을 통해서 소프트웨어적으로 찾아내어 고치는 역할을 하게 될 것이다. 본 논문에서는 이러한 Remote Debugger를 구현하기 위한 부분 중 call stack watch view 에 대해 논의 하려고 한다.

Contemporary organizations strive for customer agility through the deployment of digital technologies on customer-focused operations to build enduring customer relationships, with mobile apps being one of its prominent examples. Drawing on prior agility and ECT literature, this study proposes a model to examine customers' view of a firm's customer agility. Our empirical test of conceptual model from data collected in a field study from 128 customers demonstrated that the conceptual model offers good explanation for customers' view of a firm's customer agility through relationships among customer expectations-customer perceived firm's responsiveness-satisfaction. Data were analyzed using PLS, polynomial modeling, and response surface methodology to examine the relationships between customers' digital interactions with the firm, influence of digitized interactions on customer expectations, customers' evaluation of firm's responsiveness, and subsequent customer satisfaction.

The purpose of this study is to examine the effects of the Mobile Smart-Work IT resources on the work efficiency based on moderating effects of the perceived usefulness in the Resource Based View. The study has academic meanings and practical implications that studied widely based on moderating effects of the perceived usefulness through the Hierarchical regression furthermore on the existing study on hypothesis by standard multiple regression. The results showed that IT Infrastructure in the Mobile Smart-work IT resources by moderating effects of the perceived usefulness was found to bring positive effect on individual work efficiency and teamwork efficiency. On the other hand Business Application was found to bring positive effect on teamwork efficiency. Therefore, we expect that business firm and employees actively use the effects of the perceived usefulness with the trust that Mobile Smart-work IT resources bring positive effects on the work efficiency. It can improve this work efficiency and lead to strengthening the firm competitiveness.

The mobile-phone which Camera was put on was released at the end of 2000 and dramatically puts up the deployment ratio because not only simple Camera but also a function that the photograph which I took is dispatched was added. It is the force that demand in this year presses 600,000,000 sale of a mobile-phone is estimated to be 960,000,000 of them in 2006, and to be able to include two errands with a support model after 3G. A person of entry to a camera-module appear much. In addition, the various kinds of products open markedly which a product comes to be known widely in the world, and the application range has opened widely, and considered QCDT come to be key issues for answer to market demand. By manufacturing industry, there is peculiar culture to each industry, camera-module is the composition the various industries. The construction of true Supply-chain becomes unavoidable to make a good product. I describe the point that the situation of each supply-chain and the direction for the future by the view point of module assembly maker.

This paper identifies the main features and problems which have to be considerde when providing multicast services for mobile hosts.We also present a schme for solving these problems.To do this,we intreduce the ieda of the group view with a host status and present a multicast algorithm based on the group view concept.This paper mainly fouces on the exactly-once semantic for multicast delivery.It will provide basis for build-ing multicast servies for mobile hosts.

Viewing angle controllable liquid crystal display (LCD) associated with fringe-field switching (FFS) mode with high image quality is proposed. In the device, one pixel is composed of main and sub pixels, in which adjacent sub pixel is patterned with pixel electrodes direction orthogonal to the adjacent one. In this way, light leakage can be generated in the all viewing angle directions except the normal direction, realizing view angle controllable LCD in both horizontal and vertical directions.

In mobile browser two mental models coexist; one for mobile users and the other for PC users. In this research shows that users apply these two mental models simultaneously while they use mobile browsers. However cases where these two mental models conflict with each other, rapid deterioration of usability of the UX based on the mobile user's mental model was evident. Also usability of mobile user interfaces for use cases like "View Mode" or "Copy and Send Mode" were also poor, and the research shows that these "Modes" could be substituted by gesture interaction with which users were already familiar.

This paper proposes a mobile augmented reality mashup for cultural heritage sites such as natural monuments. Several benefits of mobile augmented reality solutions are ideal for preserving and protecting cultural heritage sites. By presenting mobile augmented reality mashup scenarios and mobile mashup framework, we introduce how user-generated multimedia contents can be added. We present two scenarios of Mashup Viewer and Mashup Maker. In Mashup Viewer mode, visitors can create new AR contents using mashup tools for memo, Twitter, images and statistical graphs. In Mashup Maker mode, other visitors also can view the user-generated multimedia AR contents using QR codes as access points. To show feasibility of our approach in mobile platforms, we compare several detection algorithms on PC and mobile platform and report on deployment of our approach in a natural monument museum. With our proposed mashup tools, visitors to the cultural heritage sites can enjoy default AR contents provided by the site administrators and also participate as active content producers and consumers.

This paper analyzes the feasibility of a new 3DTV broadcasting service scenario via Advanced Television Systems Committee Mobile/Handheld (ATSC-M/H). We suggest a dual-channel system in which a left-view image is encoded by MPEG-2 with HD quality and a small-sized right-view image is encoded by AVC. Also, the left view is transmitted through ATSC main channel and the right view is transmitted through ATSC-M/H channel. Although the transport stream formats of two channels are different from each other, we demonstrate that it is possible for the ATSC 2.0 decoder to synchronize the display of the left and right views when both encoders use a common wall clock and time stamp. We also propose a program specific information descriptor which guarantees full compatibility with the conventional 2D HDTV and emerging mobile TV services. Finally, we provide the results of subjective visual quality assessment of the proposed system in support of its 3DTV service quality.
