전력부가서비스는 전력 서비스 본질의 가치를 높이기 위한 수단으로, 전력 서비스를 제공하는 과정 중에 취득된 정보를 가공 및 활용하여 제품이나 서비스의 형태로 제공하는 것을 의미하며, IT기술의 발전에 힘입어 전력산업내의 블루오션 시장으로 성장하고 있다. 국내에서는 원격검침시스템 구축 이후 원격검침데이터를 이용한 부가서비스 시스템이 개발되어 여러 형태로 수용가에게 제공되고 있으며, 요금관련 서비스는 비교적 다양하게 제공되고 있으나 그 외의 분야에서는 아직까지 깊이있는 서비스로 발전하지 못하였다. 이는 그동안의 환경적 요인이나 정책 등의 여러 가지 이유에서 기인한 것으로 보여진다. 그러나, 최근에는 시장이 변화하고 이에 따른 표준 인프라스트럭쳐 구축에 대한 논의가 이루어지면서 전력부가서비스에 대한 관심이 높아지고 이에 대한 연구도 더욱 활발해지고 있다. 본 연구에서는, 이와 같은 국내 시장의 환경 변화와 전력부가서비스의 발전 현황, 선진 시장의 부가서비스 현황을 분석하고, 실제적인 수용가의 수요 조사 결과를 바탕으로 하여, 국내의 환경 하에서 전력부가서비스 모델의 선정과 구축이 성공적으로 이루어질 수 있는 방안을 제시하고자 한다.

This study analyzed relative importance among business model factors for improving business performance of Knowledge Service Enterprises using the Business Model methodology. It also compares and analyzes the relative importance of manufacturing enterprises by using the previous research conclusion. This study finds Product & Service factor(0.361) is the most important among Marketing(0.251), Financial aspects(0.234), and Infrastructure(0.154) are follows. For the sub factors, Value Proposition(0.254) is the most importance factors and Revenue Streams(0.154), and Key Activities(0.107), and Key Resources(0.100), and Channels(0.086) are follows. Also, The Marketing has higher relative importance for Manufacturing enterprises, whereas the Product&Service has higher relative importance for Knowledge Service Enterprises. It proves that there is a difference in the relative importance between Manufacturing Enterprises and Knowledge Service Enterprises. This study concludes the importance of business model factor is different for each respective industry. Therefore, it suggests to consider different industrial aspects when build the business model for each industry.

Along with the advent of ubiquitous computing environment, it is becoming a part of our common life style that the demands for enjoying the wireless internet using intelligent portable device such as smart phone and iPad, are increasing anytime or anyplace without any restriction of time and place. The recommending service becomes a very important technology which can find exact information to present users, then is easy for customers to reduce their searching effort to find out the items with high purchasability in e-commerce. Traditional mining association rule ignores the difference among the transactions. In order to do that, it is considered the importance of type of merchandise or service and then, we suggest a new recommending service using mining sequential pattern based on weight to reflect frequently changing trends of purchase pattern as time goes by and as often as customers need different merchandises on e-commerce being extremely diverse. To verify improved better performance of proposing system than the previous systems, we carry out the experiments in the same dataset collected in a cosmetic internet shopping mall.

IPTV 기반의 이러닝 마켓플레이스는 IPTV를 통한 이러닝 서비스 제공을 하기 위한 교육 콘텐츠 공급자와 수요자간의 마켓플레이스로써, 이는 양방향 매체 하에서의 이러닝 서비스로써 많은 관심의 대상이 되고 있으며, 방송통신융합의 초기 단계에서 IPTV는 다양한 콘텐츠와 서비스 모델의 개발을 통하여 그 효용성을 높이는데 기여를 할 수 있을 것이다. 본 논문에서는 IPTV기반의 이러닝 마켓플레이스에서 핵심적인 프레임워크를 구성하기 위하여 이러닝, e-마켓플레이스, IPTV에서의 특징과 기존의 이러닝 마켓플레이스들의 기능을 매트릭스를 통한 비교분석으로 기본요소를 추출하고, 이를 통하여 프레임워크를 구성한다. 또한 비즈니스모델 개발을 위하여 비즈니스모델설정, 참여자/역할, 제품/서비스 커버리지, 운영시나리오, 수익모델을 작성하고 이를 통하여 실제적으로 비즈니스모델의 구현이 가능한지를 검증한다.

DDoS attacks make people can't using normal internet service, because DDoS attacks cause exhaustion of network bandwidth or exhaustion of computer system resources by using many personal computers or servers which already infected computer virus from hackers. Recent DDoS attacks attack government brach, financial institution, even IT security company. IT security companies make Anti-DDoS product for defense from DDoS attack. But, There is no standard for BMT of Anti-DDoS product. In this dissertation, Anti-DDoS product quality characteristics of the survey analysis to evaluate them by comparing the assessment items were derived.

Senior business has been paid attention due to rapid global aging and baby boomers turning 60. However, senior business is not successful as expected because of a lack of understanding of consumers and small size of Korean domestic market. Understanding of senior consumers and overseas markets and providing attractive product and service contents needs to overcome the current challenges. Therefore, this study explores and compares consumers of different generation and different countries. We employ consumption value theory and analyze which consumption values are perceived strongly by each four group(Korean consumers in their 20s, Korean their consumers in 50s, Chinese consumers in their 20s, and Chinese consumers in their 50s). We conducted online survey to compare consumption values among samples of consumers in two countries: Korea and China. There are forty survey instruments in twelve consumption values. The results can be used to develop a strategy for planning, developing, distributing, and promoting product and service contents which consumers, in particular baby boomers, have a strong intention to purchase it.

Three Dimensional Printing (herein, 3D printing) not only gives novelty and interests to modern people but is also a spotlighted technology that could herald a new industrial revolution. The introduction of various 3D printing service platforms has enabled individuals to easily possess products designed through 3D printing. However, there are still many issues to consider until the era of new manufacturing, when 3D printing becomes available to the general public so that anyone can make and design products with 3D printing. For instance, there needs to be sufficient consideration and research on whether the current 3D printing services can prove their higher capability to produce products conventionally done by machines and hands through 3D printing, and on the meaning of selling a wide range of product families like those of most 3D printing service platforms to the consumers. This study, which was initiated in this context, aimed to gain insight on the directions that 3D printing services need to advance going forward by letting consumers have first-hand experience on 3D printing online service platforms with a wide range of product families and those with relatively limited services, and then asking them to answer multiple-choice and short-answer survey questions on the websites they wish to purchase from, diversity of designs, design satisfaction, perceived technical skills, perceived purchase satisfaction, perceived after-sales service(A/S). As a result, we were able to witness that consumers generally had a strong preference for services with a wide range of product families (e.g. Shapeways) compared to services with a narrow range (e.g. Digital Forming). We also verified that design diversity and the possibility of realizing the designs were the crucial aspects that need to be considered with 3D printing services. Moreover, we also carried out discussions on carrying out design consulting by securing a pool of designers from diverse fields, on providing web-based designing software that can be utilized even by beginners, and on operating shops both online and offline in order to provide more competitive 3D printing services.

In a buyer seller transaction process, "value for money" is one of the most important criteria for a buyer's purchasing decision. The terms "value" and "money" represent a composite measure of what a buyer receives from goods and/or services and a measure of what he/she pays for them, respectively. The purpose of this paper is to help buyers select the best seller in terms of value for money. We suggest DEA models for buyer seller transactions and apply them to the case of an Internet comparison shopping site in Korea. We expect our DEA models to provide valuable information for rational buyers who want to pay the least price for high quality products/services. Moreover, we expect that our models can help sellers be more competitive by showing them how to attract buyers.
