소비자의 욕구인 '개성' 및 '차별성'에 맞추어 보면, 일방적으로 CP에 의해서 제공되는 보편적인 이미지보다는 본인이 직접 만들고, 본인 취향에 맞춘 모바일 콘텐츠를 추구하는 게 당연한 현실이다. 사용자가 만든 음원을 자신의 폰에서 사용하는 기능도 서비스되고 있으며, 사용자가 간단한 이미지 편집을 통해 바탕화면이나 메시지 발송 용도로 사용할 이미지 혹은 영상을 만드는 서비스도 조만간 열릴 예정이다.

Differentiated services network (DiffServ) aims to provide the same service to a group of connections that have similar Quality of Service requirements. One of the essential function to realize DiffServ is the traffic conditioning mechanism. The paper proposes the enhanced traffic conditioning mechanism which can assure the reserved rates of TCP and UDP flows and support fair distribution of excess bandwidth. The simulation results show that the new mechanism is rather insensitive of the effect of UDP against TCP throughput, and performs better both in terms of throughput assurance and fair distribution of excess bandwidth in case of well-provisioned and over-provisioned network environment.

One of the main issues in Diffserv AS architecture is guaranteeing fairness among the flows which have their own QoS requirements. Because the methodology of resource allocation and traffic conditioning would affect the end-to-end QoS and backbone link utilization. In this paper, we propose a variant of TSW algorithm for enhancing fair bandwidth allocation and link utilization and presents performance evaluation between TSW & TS2W3C through NS-2 Simulations.

최근 들어 도시 집중화 현상 및 기반산업의 불균형적인 발전에 따른 문제를 해결하기 위해 유비쿼터스 기술 기반의 혁신도시 개념인 u-City에 대한 연구와 발전의 필요성이 대두되고 있다. 이에 본고에서는 u-City의 개요와 필요성, 그리고 기존도시와의 개념적, 기술적 차별성에 대해 분석하고 이와 관련된 요소기술들에 대하여 분석한다. 그리고 이를 바탕으로 u-City 구축 시 필요한 다양한 서비스에 대하여 분류하고, 각각의 분류에 따른 실제 서비스 적용 사례에 대하여 분석한다. 또한 이러한 u-City에서의 다양한 서비스들에서 발생 가능한 보안 문제점에 대하여 분석하고, 이를 효과적으로 해결하기 위한 보안 고려사항들에 대해 분석한다.

SK텔레콤과 KTF 등 W-CDMA 사업자들의 2006년 화두는 단연 'HSDPA'라고 할 수 있다. 3.5G 이동통신으로 일컬어지는 HSDPA는 이론상 최대 속도 14Mbps, 실제 속도 역시 3Mbps 이상을 구현할 것으로 보여 화상전화 정도만을 장점으로 내세웠던 WCDMA와는 분명히 차별점이 있기 때문이다. 특히 KT가 주도하는 와이브로 서비스가 4월경 서비스될 예정이기 때문에 이통사들의 HSDPA 서비스개시도 당초 예상보다 대거 앞당겨 빠르면 7월경 이뤄질 전망이다.

This study focuses on the process of internalizing the perception of negative discrimination among elderly people who have experienced age discrimination. The grounded theory method was used to identify the age discrimination experienced by the elderly in their daily lives and to explore the consequences of such discrimination through self-ageism. According to the analysis results, the elderly respond not only to explicit discrimination but also to implicit discrimination. In this process, the stronger the pain of old age (poverty, disease, ignorance, and solitude) and the stronger the memory of failing to respond to discrimination, the higher the level of self-ageism. "Self-ageism" has internalized the negative image of the elderly, who have been discriminated against by age, resulting in disadvantages in terms of quality of life through various reject/separate/suspension actions in reality. In the presence of supportive resources such as health, institutional support, and caregivers, the elderly have room to overcome self-ageism through more active ways. However elderly people who cannot motivate themselves and they lack these resources, elderly are trapped in negative reflux caused by self-ageism and sustained a depressed and shrinking life. In this state, it is not easy to motivate themselves and make physical, cognitive, emotional and social responses. Therefore, in this analysis, we specifically noted two aspects, contextual conditions and interventional conditions, and proposed programs for synchronizing senior citizens and improving resiliency from a microscopic point of view, and argued for the need to develop systems such as supplementing welfare and health service systems related to the entire life cycle, expanding accessibility and 'age-integration' through 'Community Care', awareness improvement and anti-discrimination laws.

This paper attempts to develop STP Strategy of EXPO 2012 Yeosu for attracting tourists. STP in marketing strategy refers to the process of market segmentation, market targeting, and positioning. I tested four demographic variables(age, occupation, nationality, and sex) to segment the market or the visitors of EXPO 2012 Yeosu effectively. The statistical result shows that age, occupation, and nationality are significant. Based on the three demographic factors and the visitor's purpose, I classified the expected visitors of EXPO into 12 groups, and selected 6 targeted groups: a group of Korean students with the purpose of study, a group of Korean professionals with the purpose of business, a group of foreign students with the purpose of study, a group of foreign professionals with the purpose of business, a group of Korean people in general with the purpose of tourism, and a group of foreign people in general with the purpose of tourism. In this paper, I have suggested a differentiated marketing mix for six targeted groups each.

Rerouting mechanisms must be used by connections in order to provide QoS (Quality of service) characterization of services, which provides mean for reliable and efficient transfer of services under fault generating network. Also, user's services can classily according to their QoS characterizations. In this paper, we study classification of user services according to their characterization for providing differentiated services, and propose rerouting mechanisms under fault generating network. For this, we study various rerouting mechanisms including rerouting locus of start (Source Rerouting, Link Rerouting), rerouting timing of start (Immediate Rerouting, Random Rerouting) and their orthogonal relationship, eventually we propose new rerouting mechanisms such as DRIT, DRDT which show higher performance according to priority of services than others. Our simulation shows that rerouting mechanism (DRDT), applied differentiated mechanisms is better performance to provide differentiated service.

전통적인 마케팅 기능이 제품에 대한 구매 욕구를 창조하는 기능, 즉 제품 소유 효용을 창출하는 반면에 물류(logistics)는 시간 및 장소 효용을 창출하므로써 제품 소유 효용을 가능하게 만드는 중요한 부가가치 창출기능이라는 인식이 증가하고 있다. 특히 품질과 가격이 비슷한 경쟁적인 성숙시장에서는 오히려 차별적 우위의 물류서비스 제공을 통해 고객만족을 시킬 수 있기 때문에 물류서비스가 지속적인 경쟁우위 개발을 위한 무기가 될 수 있다(Sharma, Grewal, and Levy 1995). (중략)
