In this paper, we introduce a quality of experience (QoE)-provisioning mobility management scheme. The emphasis is on a mobility-aware QoE solution enabling network components to recognize the mobility pattern of an end-user and to prepare a handover in advance. We further focus on an energy-adaptive QoE solution based on the energy profile providing the preferred pattern of energy consumption and an energy preference check engine determining whether the provision of the service that the end-user requested is suitable to QoE or not. Lastly, we concentrate on a network-based intelligent mobility management scheme adopting the calm service and the balance. Consequently, we conclude that the proposed schemes improve the handover latency, QoE metrics, and energy efficiency simultaneously.

클라우드 컴퓨팅 환경은 가상화 인프라를 제공하며 클라우드 서비스 참여자는 이러한 가상화 자원을 사용하여 서비스를 제공 및 활용한다. 그러나, 클라우드 가상화 환경에서의 보안위협이 지속적으로 증가하고 있는 반면, 안전한 클라우드 가상화를 위한 정책 연구는 미비한 실정이다. 이에 따라, 본 논문은 클라우드 가상화 인프라 중 클라우드 네트워크 가상화의 서비스를 안전하게 제공하기 위한 정책 방안을 제안한다. 제안하는 방안에서 클라우드 네트워크 가상화 환경에서 발생 가능한 보안위협을 도출하고 이에 따른 보안요구사항을 도출한다. 결과적으로, 클라우드 네트워크 가상화 서비스를 안전하게 제공하기 위한 정책 마련 시 클라우드 서비스 제공자가 고려해야할 보안요구사항 도출을 목표로 한다.

부모와 유아가 함께 보내는 프로그램이 많아지면서 자연적으로 부모와 유아가 함께 보내는 시간에 대한 관심이 크게 증가하고 있다. 하지만 부모와 유아가 함께 할 수 있는 콘텐츠에 대한 정보 제공 서비스는 속도를 따라가지 못하고 있다. 이에 본 논문에서는 부모와 유아가 함께 즐길 수 있는 육아 콘텐츠정보 제공 웹페이지를 설계하고 구현하였다. 부모와 유아가 함께 할 수 있는 여행지 추천, 게임, 요리 레시피 제공을 통해서 부모와 유아가 함께 할 수 있는 콘텐츠를 제공함을 목적으로 하였다. 본 논문에서 구현한 웹 페이지의 사용으로 유아를 가진 부모들의 정보제공에 도움이 되기를 기대한다.

This paper analyzes the design and usability of maternal notebook mobile application and suggests the improvement direction of the application. The researcher compared and analyzed the functions of maternal notebook applications, conducted user interviews and expert evaluations. The conclusions of this study are the use of appropriate information volume, proportional screen division focusing on main functions, the use of GNB format of main menus, the prohibition of double menu configuration, the use of color consistent with the image of the service, the use of few font sizes, the use of appropriate colors in typography, the use of rich icons with uniform design, card format, list format, but also timeline and infographic forms that make rich user interface design. Maternal notebook application research is expected to be an important reference for research on similar mobile applications with complex functions such as information provision, user history, and community, along with improved research in healthcare design.

유비쿼터스 컴퓨팅 환경을 위해서는 그 구성 개체들 간의 의사소통이 원활히 이루어져야 한다. 이를 위한 중요한 기술 중 하나가 사람이 아닌, 컴퓨터가 데이터를 이해하고 직/간접적으로 처리할 수 있도록 하는 기술이며, 그래서 도입된 개념이 온톨로지(Ontology)이다. 본 논문에서는 이러한 온톨로지을 기반으로 하는 유비쿼터스 컴퓨팅 환경 하에서 서로 다른 온톨로지를 기반으로 하는 구성개체들이 원활하게 서로 이해하고 상호작용할 수 있도록 Ontology Mediator와 Ontology Bridging Service를 기반으로 하는 Bridge Ontology 생성 및 제공 기법을 제안하다.

Purpose: This study was designed to identify the predictors of elderly women's intention to report elder abuse. Methods: A cross-sectional survey design was used. The participants were 204 elderly women aged over 60 living in Seoul. Data were collected using self-reported questionnaires by convenience sampling. Data were analyzed with frequencies, $x^2$ test, t-test and binary logistic regression. Results: Logistic regression analyses showed perception of elderly welfare law, perception of seriousness of elder abuse, subjective economic status, and exposure to elder abuse information were significant predictors of elderly women's intention to report elder abuse. Conclusions: The results of study suggest that the provision of information related to elder abuse including elderly welfare law is crucial toward elderly women in preventing elder abuse.

The telecommunications-based information technology and the provision of electronic commerce are broadening possibility of the virtual enterprise. The purpose of this paper is to enhance academic and practical understanding virtual enterprise as one of the most promising new concepts in electronic commerce area. I strive to establish the concept of virtual enterprise as a strategic source of competitive advantage in small & medium business. I analyze several new trends and concepts in strategic business area which will eventually lead small & medium business to the virtual enterprise. It has great potential benefits for small & medium businesses which are placed in difficult circumstances. They must build IT infrastructure and make use of co-sourcing for the utilization of virtual enterprise. This paper also suggests the strategic methods which enable the conventional enterprise to introduce the virtual enterprise.

The mobile industry is waking up to the reality that customers buy 'services', not technology. Thekey is to deliver a variety of differentiated services today and improve them as the advanced technology becomes available. In the increasingly data centric world of the future, the emphasis will be on the provision of a range of services audio, video, data and multimedia and of course speech. As we move closer to the realization of these mobile services in the conglomeration of converged networks, new challenges are being faced by the technology and application developers as well as the service providers to design, test and integrate new products and services. Functionalities like availability, scalability, performance and compatibility have become more important. This paper discusses the new test paradigms in the mobile networks, both from the applications and the protocols perspective.

This paper derives and computes the detection probability of timing synchronization in an orthogonal frequency division multiplexing (OFDM) system encountered with a multipath Rayleigh fading channel and imperfect noise estimation. The timing synchronization scheme using a simple repeated constant amplitude zero auto-correlation (CAZAC) training symbol and correlation techniques is adopted. With this provision, we focus on the numerical analysis for OFDM timing synchronization scheme employing a preadvancement technique to reduce the inter-symbol interference (ISI). For measuring system performance, the detection performance derived in the considered system is presented in a multipath Rayleigh fading channel.
