This study set out to analyze the impacts of convergence products(cell phones, PDAs, IPTV, and portable game consoles) on the consumers' purchase intention and satisfaction. These results of the research model show that usefulness, perceived risk, and communication had significant influences on purchase intention, and usefulness, innovation, perceived risk, and communication on satisfaction. But there were differences according to the product kinds. The results indicate that usefulness, convenience, perceived risk, and communication are the major factors affecting the satisfaction and purchase intention of convergence products and that innovation didn't have much influence on them. And there were small differences among the influential factors according to the kinds of convergence products.

This study testified the influence factors like quantities of advertising, number of hardware and software that are converged, effect on feature fatigue of convergence product. When consumers perceive higher numbers of hardwares in a smart phone, they feel its higher usefulness and complexity. This means that numbers of hardwares is the major factor that enhances consumer's usefulness but, at the same time, it cause perceived leads to higher usefulness in using smart phone, it didn't effect on complexities. It is also important strategy for smart phone companies to provide a lot of useful softwares(applications) to satisfy consumers. Finally, complexity was important factor that lead to higher feature fatigue of consumers. This indicates that smart phone companies have to find adequate numbers of convergence for their new smart phone.

Many products today tend to adopt a convergence approach by adding new features or functionalities to the existing products. The convergence, however, results in both positive and negative effects on usage of products, and thus demonstrates the characteristics called "paradox of technology." On the one hand, the added functionalities or features will increase the usefulness of the products. On the other hand, the convergence increases complexity of learning and usage of products and may decrease satisfaction or user evaluations. This study provides an empirical evidence of this paradox through investigation of telematics, one of the exemplary products of convergence services. Our research model is designed to test the existence of the "paradox of technology" and includes variables such as variety of functions, complexity of usage, perceived usefulness, service evaluation, and service fit. The proposed research model and subsequent hypotheses are empirically tested using 149 survey responses from telematics users. We have found that the variety of functions is positively associated with perceived usefulness, but is negatively associated with the complexity of usage. The data analysis reveals that the perceived usefulness has more significant impacts on service evaluation than the complexity of usage does. Furthermore, the strength of causal relationships among these variables is partially moderated by the degree of service fit. This study thus highlights the paradox of technology in explaining user attitudes and beliefs associated with convergence services.

This study is research of actual proof on verification of the user's utility about mobile convergence products and the types of convergence categorize into four types according to their characteristics. Four types of convergence; (1)Open service via scalable internet, (2)Close service dependent on mobile phones, (3)Broadcast services such as DMB, (4)Individual products such as camera based on digital technology. The purpose of research model is to identify differences in effect value of the types of mobile convergence according to its usage level and level of quality. As the result of this study, Usage level of open service/individual products had a significant effect on the user's utility about mobile convergence products, Also Level of quality of open service had a significant effect.

캠코더가 똑똑해지고 있다. 아니 디지털카메라가 똑똑해지고 있다. 휴대성을 강조하는 추세에 맞게 군살을 빼서 크기가 작아지는 것은 기본이고 합쳐야 산다는 컨버전스 시대에 맞게 서로의 경계를 넘어 기능을 꿀꺽 삼켰다. 소니코리아의 사이버샷 DSC-M1 역시 눈길을 끄는 컨버전스형 제품 가운데 하나다. DSC-M1의 액정은 슬라이드 방식을 채용, 왼쪽으로 열리고 좌우로 270도 회전시킬수 있어 언뜻 보면 요즘 유행하는 휴대전화를 닮았다. 무게는 190g으로 미니켓과 비슷한 수준이며 크기도 작아 휴대성이 뛰어나다. 기능을 보면 CCD는 2.4분의 1인치 크기이며 509만화소를 지원한다. 최대 해상도는 2,592×1,944로 웬만한 디지털카메라 뺨치는 수준이다.

In information society, Convergence was combined with a word 'digital'. Digital convergence means a service or new product which appeared through fusion of unit technologies in information and communication regions. The effects of convergence technologies and social phenomenons are visualized in overall regions of society such as economy, society, culture, etc. Nowadays, manufacturing field are facing new challenges, through digital information and global integration, toward sophisticated production. This paper presents the system configuration and issues of current manufacturing execution system(MES), and describes major issues and solving elements to establish a MES system for cloud services. Also, we propose a method for building a manufacturing information system to have the optimized production flow and to respond appropriately to consumer market.

This study is a comparatively analyzes innovation tools for developing appropriate business models according to the types of convergence. Firstly, it examines previous studies on the type of convergence, business models, and innovation tools. Based on the understanding of each topic through literature search, it introduces Convergence-Business-Innovation Tools Cube (CBI Cube) model with the concept of developing innovative business models by applying innovation tools under the condition of convergence. In order to quantify (concretize) the concept, we have compared the relative priority of innovation tools for developing business models to find component factors of CBI Cube model through the survey of an expert group by adopting DelPhi method and AHP method. From the result of this study, we expect to be able to make an easier approach to the development of innovative products, services and market as it allo ws to develop business models of value innovation beyond just benchmarking or simple imitation of existing business models.

지난 해‘PMP 열풍’으로 디지털 컨버전스라는 개념이 일반인의 머리 속에 깊이 자리 잡았다. 디지털 컨버전스하면 단연 휴대폰일 것이다. 휴대폰은 어떤 모바일 기기보다 기능이 많다. 현재 이러한 휴대폰의 인기에 편승해 휴대폰 형태로 디자인 된 MP3 플레이어와 디지털카메라가 속속 시장에 모습을 드러내고 있다. 웨이키안 DV-6500은 폴더 타입 휴대폰을 연상시키는 디자인에 7가지 멀티미디어 기능을 담은 최근 경향에 충실한 제품이다.

디지털컨버전스가 더욱 더 본격화되면 가전제품에서 보아왔던 것처럼 단순한 제품간의 기능의 통합을 넘어 금융상품이나 방송서비스, 신용카드 등 다양한 분야의 결합이 가능해지고 각 기기간의 데이터 교환이 상호 가능해진다. 따라서 모든 제품간의 네트워크화를 이루게 되어 생산자와 소비자간의 유기적 결합을 통한 새로운 산업환경의 변화를 이끌어 내리라는 전망이다. 특히 최근 각광을 받고 있는 멀티미디어인 휴대용 동영상 플레이어(PMP), 개인 정보단말기(PDA), 디지털 멀티미디어 방송(DMB), 디지털카메라 등 여러 가지 형태의 디지털 미디어와 IT기술의 결합이 예상된다.

본 연구는 시선 추적 방법(Eye-Tracking Method)을 이용한 디지털 컨버전스 제품의 정보 설계 및 평가에 관한 방법론을 제시하였다. Eye-tracking 데이터는 visual search의 효율성 뿐 아니라 타겟의 유의미성이나 가시성등을 측정하는데 유익하다. 응시 횟수와 응시 시간을 통하여 사용자의 심성 모형에 따른 시선 행위와 제품 메뉴 구조간의 전체적인 일치도를 정량적으로 분석하였고, 각 메뉴 item의 세부적인 인지 반응 정도를 평가하였다. 컨버전스 제품의 한 예로 휴대폰을 선정하여 실험을 실시하였으며, 활성화 확산 실험(SAT)을 수행하여 메뉴 항목 상호간의 인지반응 정도를 통한 문제점을 도출한 후 사용자 시나리오를 작성하였다. 1차 테스트를 통하여 피실험자의 시나리오 수행 시 어려움을 알 수 있었으며, 1차 테스트의 결과와 인터뷰 결과를 바탕으로 프로토타입의 메뉴명을 개선하여 2차 테스트를 실시하였다. 실험 결과 개선 전보다 후의 응시 횟수, 응시 시간 또한 감소하여 수행도가 향상됨으로 메뉴 구조의 개선된 결과를 가져왔다. 본 연구는 인간의 눈 움직임 측정치 결과를 토대로 사용자 심성 모형에 부합하여 누구나 접근이 쉬운 정보 구조를 설계할 수 있었다. 그러므로 본 연구에서 제시하는 Eye-tracking Method는 디지털 컨버전스로 인한 복잡한 정보 구조의 설계와 평가에 기여할 것으로 보인다.
