소프트웨어를 개발하는데 미리 구현된 블록을 사용하여 소프트웨어 개발 비용과 시간을 단축할 수 있다. 이와 같이 미리 구현된 블록을 컴포넌트(Component)라고 하며 컴포넌트는 실행 단위로 개발자에게 인터페이스만을 제공하여 내부 상세한 부분을 숨기므로 쉽고 빠르게 어플리케이션을 개발할 수 있다. 그러나 인터페이스 만을 이용하여 시스템을 개발하는 컴포넌트는 범용적으로 많은 도메인에 사용될 수 있도록 컴포넌트를 개발해야 한다. 어플리케이션 개발자는 완전히 내부를 볼 수 없는 블랙 박스(Black Box) 형태의 컴포넌트를 원하며 개발 도메인의 특성에 맞게 속성 및 워크플로우(Workflow)의 변경을 원하기 때문에 워크플로우를 커스터마이즈(Customize)할 수 있는 기법이 제공되어야 한다. 이러한 커스터마이즈 기법에 따라 컴포넌트의 일반성이 좌우될 수 있다. 본 논문에서는 컴포넌트의 일반성을 향상시킬 수 있는 워크플로우 커스터마이즈 기법을 제시한다. 기존에 워크플로우를 변경한다는 것은 컴포넌트 내부를 개발자가 이해하고 코드 수준에서 수정해야 하는 화이트 박스(White Box)이지만, 본 논문에서는 워크플로우의 변경을 화이트 박스가 아니라 블랙 박스 형태로 컴포넌트 인터페이스 만을 이용해 커스터마이즈 할 수 있는 기법을 제시하며 이러한 기법을 통해 일반성을 향상 시킬 수 있도록 한다.

NGN is a packet-based converged network to support session and non-session services in QoS-enabled broadband transport network. QoS based resource control must be defined to support differentiated services for various network users in NGN. We designed and implemented DIAMETER protocol as the Rs interface, and also defined mapping rules between DIAMETER information elements and SDP(Session Description Protocol) attributes for QoS based resource control in NGN. We selected and implemented DIAMETER protocol among alternate resource control protocols in ITU-T as the Rw interface because of simple interworking method with Rs interface and adequate AAA functionality. We defined mapping rules of messages and information elements between Rs and Rw interfaces for resource control from a service layer to a transport layer. Based on the mapping rule of QoS information elements and the interworking method between Rs and Rw interfaces, we built up a test-bed that support differentiated delivery services.

This study reviews the limit of image search by considering on the image search methods related to content-based image retrieval and suggests a user interface for more efficient content-based image retrieval and the ways to utilize image properties. For now, most studies on image search are being performed focusing on content-based image retrieval; they try to search based on the image's colors, texture, shapes, and the overall form of the image. However, the results are not satisfactory because there are various technological limits. Accordingly, this study suggests a new retrieval system which adapts content-based image retrieval and the conventional keyword search method. This is about a way to attribute properties to images using texts and a fast way to search images by expressing the attribute of images as keywords and utilizing them to search images. Also, the study focuses on a simulation for a user interface to make query language on the Internet and a search for clothes in an online shopping mall as an application of the retrieval system based on image attribute. This study will contribute to adding a new purchase pattern in online shopping malls and to the development of the area of similar image search.

Introducing human capacities of control and sensation which have been overlooked into Human-Computer Interaction(HCI), Ubiquitous computing, Augmented Reality and others have been researched recently. New vision of HCI has embodied in Tangible User Interface(TUI). TUI allows users to grasp and manipulate bits with everyday physical object and architectural surface and also TUI enables user to be aware of background object at the periphery of human perception using ambient display media such of light, sound, airflow and water movement. Tangibles, physical object which constitutes TUI system, is the physical object embodied digital bit. Tangibles is not only input device but also the configuration of computing. To get feedback of computing result, user controls the system with Tangibles as action and the system represents reaction in response to User's action. User appreciates digital representation (sound, graphic information) and physical representation (form, size, location, direction etc.) for reaction. TUI's characters require the consideration about both user's action and system's reaction. Therefore we have to need the method to be concerned about physical object and interaction which can be combined with action, reaction and feedback.

When the developers develop the software, the cost and time of the software development can be reduced by using blocks that are implemented previously. We call these implemented blocks components. They provide only the interfaces of component to developers, while the detailed infernal information is being hidden. The components can be used to develop large applications fast and easily. Developers use the black-boxed components that the internal details of components are invisible. But, Developers want the properties and workflows of components to be modified. To do this, the customization technique is needed. The existing customization techniques are limited in the customization of component properties. In this paper, it proposes the technique that can change the workflow of component as well as properties In the business point of view. In the existing workflow customization technique, which is called white box component, the internal details of component should be understood by developers and should be modified in code level. In this paper, we propose a customization technique which using the component interface in black box form only. This customization technique can be used more generally in a business field.

'Digilog Book' integrates advantages of existing paper book and immersive digital contents in augmented reality environment, which enables users to feel physical touch and get additional multisensory feedback. As a high level authoring user interface, 'ARtalet' provides an intuitive way to make Digilog Book through 3D user interface in augmented reality environment. This paper mentions trajectory inserting and editing methods of 3D objects, then combining method of the trajectory. 3D object is selected by camera tracked prop, and then transformation matrix relative to book plane is stored in real time based on timeframe. The saved trajectory is managed as templates, and user can make various compositions of trajectories. We expect that suggested methods can enhance interest of readers.

The purpose of this paper is to study a scheme to ITS service which enables the data (spatial, non-spatial and image) sharing among heterogeneous system (various environment) with employing the concept of object orientedness and to show Location Reference Technique of ITS Space DB for interoperability. Data warehouse service, query object service, interface object service, and naming object service have been identified for this. In addition, a metadata management object service and persistent object service based system framework has been devised. The proposed skeletal framework would be expected to be functioning well for ITS data sharing environment and for the interoperability support.

Audio-based SNS also needs a visual guide to reach the contents desired by the users. Therefore, this study investigates visual interface design elements that influence the experience of using audio contents in audio-based SNS. Prior researches have identified that the generally acknowledged interface design elements are important for the usability of audio contents. Through the analysis of the currently launched audio-based SNS, the influence of general interface elements were again confirmed, and via the analysis of other audio content services, a new interface evaluation element was explored. Accordingly, with five general interface evaluation elements-layout, color, icon, typography, graphic image, multimedia elements are newly defined and proposed as crucial factors in evaluating the UI of audio-based SNS.

This paper introduces a difference between mobile Augmented Reality (AR) authoring and desktop AR authoring, and suggests an interface system that can be applied to in-situ authoring of AR contents on a mobile device. The mobile devices have enabled users to use the AR system anytime and anywhere. It is now necessary to create user's individualized context information using mobile devices on the spot. To author AR contents easily with mobile devices, we need to maximize the convenience of mobile systems, which have yet limitation. To do so, this paper suggests new interaction approaches that manage augmented contents using visual cues and other simple attribute settings. In addition, to solve the problem that users have to hold their mobile devices to track markers while authoring contents, this system enables users to author contents in environment based on captured images. This interface system also can make cooperation environment for more than one users to author contents. This paper verifies the usefulness of the proposed interface by user tests. The results of an analyzing users' comments show that the proposed interface is suitable for in-situ mobile authoring system.
