Objective: This study introduces user experience measurement and its application for senior friendly products. Background: Measuring user experience for senior friendly product is very important for its design, but the measurement is not easy. Method: This study was focused on case studies for user experience measurement and its application for senior friendly product. Mobile patient lift and four wheeled walker that assist the old's mobility were studied. User experience was measured through interview and observation method. Result: From measuring the user experience, some usability issues were identified for the products. A method to apply QFD(quality function deployment) in design process was proposed. A design prototype was also developed considering user experience. Conclusion: User experience measurement for senior friendly products is key process for user centered design. Application: The method and result of this study can be applied to user experience measurement and design of senior friendly product.

Recently, with the increasing use of power semiconductors and microprocessors which are very sensitive to little change of power quality and for coping positively with anticipating power quality disputes between power providers and consumers which are possible to occur by of power market being formed, the power quality problem has gained preponderance among the contemporary research areas. To serve these purposes, the integrated system has been researched and developed for power quality analysis and monitoring, which provides speedy and powerful functions by the growth of computer hardware and information technology. But the advent of fast and lower price hardware make little difference in an application on many systems. As a result, the key issues of constructing power quality monitoring system are in the management of data obtained, accurate algorithms, graphic representation and user-friendly-environment for easy and clear analysis results. So, in this paper it will be introduced that the standard of user-friendly-GUI(Graphic User Interface) and analysis graphic representation for intuitive understanding of results from power quality analysis based on consideration of several systems currently being in use.

With the development and rapid growth of cloud computing, lots of application services based on cloud computing have been developed. In addition, cloud-based DRM systems have been developed to support those services' copyright and privacy protection. In this paper, we propose a new cloud-based user-friendly DRM system, which allows users to execute the same contents bought at most n times at any devices with license enforcement, which checks the validation of licenses before every execution, having no smart card, which has to carry a smart card reader that seems troublesome to a user, and providing the copyright and privacy protection.

The purpose of this study is to provide suggestion for the establishment of a living information environment for a family-friendly living environment. The survey data on a sample of three hundred and eighty-four married respondents with at least one child in elementary school that were collected for 15 days from April 16 to April 30 of 2010 were analyzed. The results are as follows: It is important to establish a family-friendly living information environment as one of the important elements for a family-friendly living environment. Two aspects ought to be considered in establishing a family-friendly living information environment. One is the supply aspect of the family-friendly living information: this encompasses the usage of facilities in the community, the residents in the community as leaders and the user-friendly living information. The other is the user aspect of the living information, which involves the education on living information for the residents in the community.

본 논문에서는 이진 이미지 기반의 간단하고 사용자 친화적인 (n,n) 시각 비밀 분산 방법을 제안한다. 제안한 방법은 간단한 XOR 연산과 NOT 연산만을 이용하여 사용자 친화적인 이미지들 내에 숨기고자 하는 비밀 이미지 정보를 분산해서 숨기는 기법으로, 효율적인 숨김(em-bedding)과 복원(reconstruction) 알고리즘 제공, 비밀 이미지의 손실없는 완벽한 복원 기능 제공, 사용자 친화적인 의미있는 이미지들을 공유함으로써 자신이 속해있는 그룹을 쉽게 구분할 수 있는 기능 제공, 그리고 기존의 방법과 달리 원본 커버 이미지와 같은 크기의 비밀 이미지를 공유할 수 있는 등의 시각 비밀 분산 방법이 갖추어야하는 많은 장점들을 가진다.

Through this study, some considerations to be taken into account in order to construct the user model for the user friendly system which can provide each individuals user armed with varied intellectual level with the relevant information, can be summarized as follows : (1) The user' ability to use the system and users' subject knowledge, the distribution of the users' level knowledge should be considered for the decision of the typed of interaction between the users and the system. (2) the knowledge of the user models should include the following kinds of knowledge inharmony with one another, 1. Standard user knowledge which represents a general characteristic of user group, 2. individual user knowledge which represents an individual's unique characteristic, 3. Long-term user knowledge which represents the education level and subject background of users, 4. short-term user knowledge which represents the purpose of information science and information need by users (3) As knowledge generation technique, both the implicit method and explicit method should be a n.0, pplied, observation of the system during the interaction, and explicit method generates the knowledge by the user's answering the questions already made by the system. (4) The frame technique as the knowledge representation for the user-modelling in which user-knowledge is represented in a limited situation and in a qualitative aspects, can be recommended. The frame is adequated for the explanation of structured situation, and for the processing the present situation by inferring the previous experiences.

In this paper, a user-friendly mobile photo album system and albuming functions to support it are introduced. Stand-alone implementation in a mobile device is considered. The main idea of user-friendly photo browsing for albuming functions is to enable users to organize and browse their photos along semantically meaningful axes of events, personal identities, and categories. Experimental results demonstrate that the proposed method would be sufficiently useful and efficient for browsing personal photos in mobile environment.
