Social networks can be a powerful force in marketing because they provide new ways to market to young generation. Though many studies on evaluation of customer lifetime value have been conducted, it is not clear how to assess the value of members within social networks. The purpose of this study is to evaluate members based on customer intangible value as well as customer lifetime value. Customer network value in terms of the power and influence within a network is analyzed through network structure analysis. Using Cyworld log file data, this study have shown that high percentage of members are very influential in terms of spreading or withholding information even though their CLV is low. It is expected that the findings of this research contribute to understand the interactive behaviors of members within networks and to provide valuable implications on new product launching and customer management strategies to marketers.

무선통신망의 망고도화로 3세대 이동통신 서비스가 개시됨에 따라 소비자들은 다양한 서비스와 콘텐츠를 제공받을 수 있게 되었다. 현재의 모바일 무선인터넷은 네트워크를 소유하고 있는 이동통신사들이 사실상 전권을 행사하고 있어 폐쇄적 성격이 짙다. 하지만, 작년 Google이 개방형 모바일 플랫폼 "안드로이드"를 공개한데 이어, 최근 LGT의 무선인터넷서비스 "OZ"의 런칭으로 무선인터넷 활성화에 대한 기대감이 높아지고 있다. 기존의 무선인터넷 산업에 대한 연구는 선형적인 가치사슬에 기반하여 해석되었기 때문에, 복잡한 네트워크로 진화해가는 해당 산업에 대한 명확한 분석을 할 수가 없었다. 따라서, 본 연구에서는 가치네트워크 개념을 도입하여 모바일 플랫폼의 개방이 이동통신 가치네트워크에 미치는 영향에 대하여 연구한다.

This study attempts to identify how the value network of mobile industry has evolved in the value creating process. The longitudinal case study on SK Telecom was conducted by measuring the SK Telecom's investment structure during from 1999 to 2008. Results show that the convergence services based on the advanced mobile networks changed the revenue structure, and enabled SK Telecom to reposition as a media company. For the value creation, SK Telecom's value network has flexibly adapted to convergence environment through dynamic asset reconfiguration.

It has been verified in several studies that dynamic capabilities has a very important effect on the competitive advantage of technology startups. And the network has an important influence on this dynamic capability. This is even more important for start-ups that lack the resources and knowledge. Networks that directly and significantly affect dynamic capabilities have been studied mainly the value chain internal. However, network activities of start-ups are conducted not only with the value chain internal networks but also with the value chain external networks. Therefore, it is necessary to study the effect of the value chain internal and external network activity of start-ups on the dynamic capabilities, but prior studies are lacked. In this study, We make a model that encompass the value chain internal and external network for technology startups, and a study was conducted to demonstrate the effect on dynamic capabilities and competitive advantage. As a result of the study, value chain internal network activity directly and significantly affected dynamic capabilities, and value chain external network activity did not directly significantly affect dynamic capacity. And dynamic capabilities had a significant effect on competitive advantage. As confirmed through additional research, value chain external network activity affects value chain internal network activity, and through this, dynamic capabilities are strengthened, and positively affect competitive advantage.. The intensity of value chain external network activity was not significant to dynamic capabilities and the diversity of value chain external network activity had a significant effect on the competitive advantage by double mediating the value chain internal network activity and dynamic capability. Through this study, it is confirmed that the value chain internal networks is important in order for startups to strengthen their dynamic capabilities and increase their competitive advantage, and that both strong and diversified the value chain internal networks positively affects competitive advantage by enhancing dynamic capabilities.

본 논문에서는 Internet Service Provider(이하 ISP)의 네트워크에 위험이 발생할 경우 위험의 출현으로 인한 ISP의 자산손실을 추정하는 방법을 제안한다. ISP의 네트워크를 구성하는 자산들의 가치를 서비스 측면에서 분석하고, 개별 자산이 생산하는 서비스 가치를 근사할 수 있는 방법론을 제시함으로써 네트워크의 장애로 인한 손실액을 추정 가능함을 보인다. 또한, 네트워크의 부하 분산, 우회 경로 및 백업 시스템 등 서비스 연속성을 확보를 위한 잉여 설계가 있을 경우, 자산가치 특성함수를 사용한 손실액 추정모델을 제안한다.

This study is about an apparel industry in Guro-Gasan where is growing up to the one of the apparel industry cluster beyond an agglomeration in Seoul. The purpose of this study is twofold: (1) to define industrial functions and roles of Guro-Gasan in a value chain of the apparel industry; and (2) to understand whether an industrial cluster is built on the local networks. This study reviewed formation and transitions of its local industries and industrial size, characteristics, spatial distribution and spatial properties using GIS analysis and field surveys. Through in-depth interviews, it analyzed the production system and spatial dispersion of the value chain to understand its functions and roles.

현재 홈네트워크 산업의 부진과 문제점 현황을 정리해 보면, 이용자 입장에서는 꼭 필요한 서비스라고 느낄 수 없다는 점과 비용 대비 가치의 불만족 등 유용성의 문제점이 있으며, 소비자의 낮은 인지도와 상품 이해도의 용이성 문제를 언급할 수 있다(이희상 외, 2006). 본 연구에서는 Davis(1989)가 제안한 기술수용모델에 기반하여, 현재 홈 네트워크가 설치된 서울 시내의 아파트 주민들을 대상으로 인지된 유용성과 용이성이 홈 네트워크에 대한 사용의도에 미치는 영향을 실증적으로 분석하였다. 나아가, 홈 네트워크에 대한 사용의도가 해당 아파트의 주거가치에 대한 인식에 어떠한 영향을 미치는 지도 연구하였다. 그 결과, 인지된 용이성과 유용성은 홈 네트워크에 대한 사용의도에 정의 영향을 미쳤으며, 그 중 용이성은 유용성에 대한 선행변수로 작용함을 확인하였다. 또한, 홈 네트워크에 대한 사용의도는 해당 주거지에 대한 가치를 제고하는데 영향을 미침을 입증하였다.

This research focus on the value of smart phones for university students in Korea, considering on the correlations between the main causes influencing intrinsic value(price attributes, function attributes), network value(learning effects attributes, externalities attributes) user satisfaction, and intentions of repurchase of the smart phones market in Korea. Through the statistical analyses on the 8 hypotheses from a research model, we found that intrinsic value and network value gave an attentive influence on user satisfaction and repurchase intention. Call charge and Liquid crystal display and Design of smart phone have an influenced user satisfaction and repurchase intention.

Measuring the intangible asset has been vigorously studied for its importance. Especially, the value of character in media industry is difficult to quantitatively evaluate in spite of the industry's rapid growth. Recently, the Social Network Analysis (i.e., SNA) has been actively applied to understand human usage patterns in a media field. By using SNA methodology, this study attempts to investigate how the character network characteristics of media works are linked to human search behaviors. Our analysis reveals the positive correlation and causality between character network centralities and character search data. This result implies that the character network can be used as a clue for the valuation of character assets.

Primarily working on SNS(Social Network Service) platform, the SNG(Social Network Game) utilizes friends and neighbors for invitation and play. Based on the value model of HCI, this paper purports to discover how functional, hedonic, social and personal values predict the continuous usage intention and satisfaction of SNG in a smartphone. Hypothesis testing through structural equation modeling shows that hedonic and functional values affect satisfaction and intention to use of SNG while social and personal values do not. This result implies that fun and easy interface are more important to the success of SNG service than social networking motivation.
