The proliferation of electronic commerce(EC) has led manufactureres to consider Internet based marketing as a salient candidate for strategic diversification of marketing channel. In this case, each manufacturer can build its own Web store or rent an existing special EC store. Such decision making of ‘build’ or ‘rent’ can be analyzed by a game model which derives the Nash solutions for price and profit considering degree of competition with other competitive manufacturers. In this paper, to overcome the drawbacks of the traditional linear demand function, we first propose a new linear demand function which incorporates not only the price difference between competitive products but the awareness of Web stores perceived by the consumers, then design the game models to analyze the characteristics of three typical types of marketing channel in duopoly market. Based on the Nash solutions of the game models, we analyzed the effect of the degree of competition and Web awareness in selecting the optimal marketing channel.

의료 영상 정보의 운용을 위한 표준인 DICOM(Digital Imaging and Communications in Medicine)은 의료 영상의 전송과 저장에 관한 방식을 제공하고 있다. 환자가 병원에서 획득한 영상은 DICOM 파일로 만들어진다. 본 논문은 DICOM 파일의 정보를 데이타베이스에 저장하고 웹서버의 구성요소로 의료 정보를 구성하여 사용자가 인터넷을 통해서 웹서버에서 제공하는 의료 정보를 볼 수 있게 하는 웹 기반 의료 정보 시스템 설계, 구현 기법을 제시한다. 데이타베이스에는 환자와 영상에 대한 정보를 DICOM 파일의 그룹과 요소별로 읽어서 저장했다. 파일 전동 모듈은 DICOM의 서비스 중에서 Store 서비스를 구현하여 IP 주소를 가진 컴퓨터와의 파일 전송이 가능하도록 만들었다. 위와 같은 파일의 전송과 저장에 대한 서비스를 웹에서 제공할 수 있도록 웹 컴포넌트로 각각을 구성하였다.

This research categorizes and analyzes different online fashion store studies conducted over the past 10 years based on study type. The results are as follows. First, it was found that 116 studies out of 118 studies on online fashion stores conducted from 2000 to 2012 were based on PC web. Second, the studies on PC web-based fashion stores were reclassified into 9 different categories based on their topics: purchase behavior, word-of-mouth behavior, website, and product information presentation as well as products for sale, return behavior, customer service, system, present condition, marketing strategy, and promotions. However, mobile web-based studies were categorized into 2 categories of introduction of the fashion stores and purchase behavior. Third, we reclassified the studies chronologically to observe studies conducted at different times. In the early phase (in addition to studies on purchase behavior) studies on present condition, marketing strategy, and website constituted the majority of studies conducted because the field research was just starting to grow; however, studies conducted in the latter phase showed new patterns of study, such as word-of-mouth effect, and return behavior. Future studies conducted on competitive PC web-based fashion stores require a more specific classification of studies (according to their purpose) to develop an effective marketing strategy.

Recently, as construction of information infra including high-speed communication networks remarkably expands, more various information services have been provided. Thus the number of internet users rapidly increases, and it results in heavy load on Web server and higher traffics on networks. The phenomena cause longer response time that means worse quality of service. To solve such problems, much effort has been attempted to loosen bottleneck on Web server, reduce traffic on networks and shorten response times by caching informations being accessed more frequently at the proxy server that is located near to clients. And it is also possible to improve internet performance further by allowing clients to share informations stored in proxy caches. In this paper, we perform simulations of hierarchical proxy caches with the 3-level 4-ary tree structure by using real web traces, and analyze cache hit ratio for various cache replacement policies and cache sizes when the delayed-store scheme is applied. According to simulation results, the delayed-store scheme increases the remote cache hit ratio, that improves quality of service by shortening the service response time.

미국 Apple 사의 App-store와 같은 모바일 어플리케이션 오픈마켓이 국내의 통신사를 통하여 서비스를 하게 되었다. 이에 따라, 국내 개발자들이 어플리케이션을 개발하여 유통을 하는데 많은 관심을 가지게 되었다. 하지만 App-store의 i-Pod과 같이 단일 모델과 다르게 국내 모바일의 종류가 너무 많아서 개발자들이 모든 단말기를 테스트 해볼 수 없다. 이를 해결하기 위해서 본 논문에서는 웹에 모바일 시뮬레이터를 탑재하여 여러 개발자들이 쉽게 모의 단말기 테스트를 할 수 있는 시스템 제안한다. 이 시스템을 통하여 개발자들이 많은 단말기에 테스트 하는 것을 간소화하고, 검증된 어플리케이션을 유통할 수 있다.

A Smartphone has an ability accessing Internet by URL stored in NFC(Near Field Communication) Tag for storing the information of items, blogs and web pages. Because the system works through the Internet with URL, however, it needs to pay some costs like communication fee and time. If we can store the web page on the tags, we can save the communication overhead. But they have too small memory to store it. In this paper, we introduce the Micro-Webpage technology which can be stored in NFC tag or QR(Quick Response) code. To make a Micro-Webpage, we remove control tags from the web page to leave a user original content. The removed control tags are stored in our smartphone application as a template. The user content is also compressed to a smaller one by an lossless compression algorithm. When a tag is read, the stored content is decompressed and, it is combined with the template to make the original web page. We have implemented a prototype of Micro-Webpage system on Android platform and confirmed that the prototype has reasonable performance improvements in saving memory and loading web page time.

In-store atmospherics involve quantified physical and social aspects; however, the social quality of a web-based retailing context has largely been under-examined. This study addressed some antecedents and consequences of social ambience in virtual shopping (or e-social ambience) within a web-based U.S. retailing fashion context. This study explored the role of social cues as a viable antecedent to e-social ambience and emotions as its consequence. A conceptual framework was built postulating the effect of social cue for web content, on e-social ambience, emotions, and e-shopping enjoyment. The experimental results (n=488) on a fictitious retail T-shirt website confirmed the positive correlation among the variables; in addition, the level of social cues included within the web content significantly increased the level of customer-perceived e-social ambience of the website and subsequent positive on-site emotions. On-site emotions positively influence purchase intentions. The results expand the current understanding of e-store management by providing novel insight relevant to fashion companies that wish to provide customers with a quality website shopping experience.

This study identifies meaningful factors that influence relationship switching intention and multi-channel use intention for department store customers. Two types of commitment (affective and calculative commitment) are proposed as mediators between satisfaction and behavioral intention. A web-based survey collected fashion product data from consumers who had a relationship with a department store. A total of 150 responses were analyzed by frequency analysis and reliability analysis, CFA, and SEM analysis with SPSS 18.0 and AMOS 18.0. Department store attributes were composed of four factors (product, salespersons, facilities and place, and price and promotion). Department store satisfaction was specified as a second order latent construct which was reflected in the satisfaction with the four department store attributes. Department store satisfaction had a significant negative influence on calculative commitment and a positive effect on affective commitment. Calculative commitment affected switching intention and affective commitment determined multichannel use intention. This study has implications for retail marketers that target fashion consumers and academics who research consumer behavior in retail settings. The most important result is that the affective commitment and the calculative commitment serve different functions. Department store managers need to make an increased effort to instigate an affective customer commitment in order to reduce switching intention.

최근 다양한 모바일 플랫폼과 애플리케이션 스토어에 대한 문제가 점점 커져가고 있다. 그에 발맞추어 최근 애플리케이션 시장규모는 대대적으로 웹으로 넘어가고 있으며, 스토어 또한 같이 성장해 가고 있다. 그러나 현재 출시된 웹 애플리케이션 스토어는 한 스토어에 종속적인 단점을 가지고 있어, 사용자로부터 스토어에 종속된 애플리케이션에 대하여 타 플랫폼에서는 애플리케이션을 사용할 수 없어 사용자에게 폭넓은 선택을 제한하며 불편을 가져다준다. 본 논문에서는 이러한 단점에 대한 해결책으로 웹 애플리케이션 스토어의 연동 모듈을 설계하고, 이를 토대로 웹 애플리케이션 연동 시나리오를 구현한다. 웹 애플리케이션 스토어의 기본 구조는 OMA(Open Mobile Alliance)에서 제안한 TAS(Telco's Application Store)를 따랐으며 기존 TAS의 모듈에 연동을 위한 모듈을 추가 확장하여 설계하고 이를 OWS(Open Web Store)라 명한다. OWS는 차세대 웹 언어를 사용하는 웹 애플리케이션을 다루기 때문에 애플리케이션 플랫폼에 독립적인 성향을 가지므로 소비자는 운영체제, 브라우저, 단말기 등의 종류에 구애 받지 않고 다양한 애플리케이션을 접할 수 있다. 본 논문에서 OWS간 연동을 위한 시나리오를 구상하고 프로토타입을 구현하여 기존의 애플리케이션의 단점을 보완할 수 있는 방법을 제시한다.
