This study provides a framework to assess network design under the regime of QoE (Quality of Experience). Our approach is expected to reveal the necessity of developing the QoE measures and applying this notion to network design, particularly in the mobile environment. Furthermore, our model shows the ample potential that both users and network providers are able to attain a win-win case by shifting the focus on network design and service operations from QoS (Quality of Service) to QoE. Since the former considers only relevant technological specifications, it may fail in capturing critical factors surrounding users, such as a context where the corresponding user is working on. For example, according to one study [13], the bit-rate, a widely employed QoS measure, shows inferior performance in provisioning network resources to the MOS (Mean Opinion Score), a representative QoE measure. Our framework develops the idea and construct a prototype to systematically assess network design and operations in terms of QoE. The proposed prototype aims at achieving a higher level of efficiency without severely deteriorating users’ satisfaction level. We also provide some simulation results which support our idea. That is, reducing the chance of over-provisioning on the basis of the QoE paradigm results in a great flexibility. It may give price cut for users or postponement of network investment for providers or both. Our simulation results also seem robust irrespective of the forms of the QoS-QoE relationship.

The number of contracts for bundling services in a domestic telecommunication market records 1.3 miilion as of the first half year in 2007, and steadily increased to 8.97 million in 2010, to 12.76 million in 2013. In 2014, 70.4% of telecommunication service consumers are found to subscribe to bundling service. Bundling services provide consumers with benefits such as price discount, convenience, increase ARPU. However, a market dominant player in a specific market may transfer its market power to another market by selling bundling services. SSNIP has been adopted to provide a market definition. However, SSNIP is not suitable to measure the effect of market power transition through bundling services because SSNIP cannot measure the effect of changeover sales of bundling services. Thus, in this study, we have investigated the effect of market power transition through bundling services reflecting market power effect and quality upgrade using Gross Upward Market Power Pressure Index metho and reviewed UPP and derivative UPP models.

차세대 IPTV 비즈니스 모델 개발을 위한 소비자 가치 분석

신민수(Minsoo Shin),김성희(Sung-Hee Kim),조철희(Cheol-Hye Cho) 한국통신학회 2011 韓國通信學會論文誌 Vol.36 No.1

IPTV는 2010년 초반 가입자가 200만 명을 넘어서는 등 빠른 성장세를 보이고 있다. 그러나 이러한 성장세의 지속 여부에 의문이 제기되고 있다. 이러한 의문은 IPTV 성장의 주요 기반이 서비스 자체의 경쟁력에 있느냐 하는 점과 2010년 들어 가입자 증가 속도가 둔화되고 있으며, 가입자 수의 증가에도 불구하고 IPTV 사업자들이 수익을 내지 못하고 있는 점 등 때문에 제기되었다. 이러한 현상은 현재의 IPTV 서비스가 시장에서 요구하는 적절한 서비스 위치를 확보하지 못하였기 때문에 발생한다. 본 연구는 이러한 문제점을 해결하기 위해, 케이블 TV 가입자들의 IPTV로의 전환 요인이 무엇인지를 밝혀내어 소비자들이 인식하고 있는 IPTV 만의 서비스 가치가 무엇인지를 분석한다. 그리고 이러한 전환 요인 중 모바일 IPTV 비즈니스 모델 구성시 반드시 고려해야 할 요인이 무엇인지를 분석한다. 또한 모바일 IPTV서비스로부터 소비자들이 획득하고자 하는 가치와 IPTV서비스 제공과 관련된 사업자 등이 제공하고자 하는 서비스 가치 간에 어떠한 차이가 있는지를 밝혀, 모바일 IPTV 서비스 제공시 소비자 가치에 부합되는 서비스를 제공하기 위한 전략적 요인들을 제시하고자 한다. IPTV was introduced as the new growth engine of the broadcasting and telecommunications industry and has experienced a high growth rate as its subscribers exceeded 2 million in early 2010. However there have been some doubts on if the IPTV market will keep current growth drift. One of such suspicions is that IPTV market has not been developed by the competitiveness of IPTV industry itself. In addition, the recent slowdown of subscribers’ growth and IPTV players’ operating at a loss has been suggested as obstacles to the IPTV market growth. This sort of phenomenon has been brought about by ambiguous proposition of IPTV's own value as well as IPTV service positioning gap. To resolve these problems this study empirically investigates what customers want to get from IPTV service by analyzing switching value of IPTV subscribers. This study also identifies which values must be strategically considered to develop next generation IPTV services, in particular mobile IPTV services. Following the investigation, this study analyzes the possible positioning gap of mobile IPTV. Through this analysis, this study suggests which sort of service values need to be reconciled.

Recently, T-Commerce is emerging to provide new services, with the proliferation of digital broadcasting services. However, T-Commerce market and TV home shopping market are being classified as a legal ‧ policy on other markets, such as regulated in the service of live broadcasts. The factor that has inhibited activation T-Commerce related to the lack of appropriate institutions and legal systems in the market, despite the environment with the digital broadcasting service is being spread. We were performed conjoint analysis. For this analysis, we select attributes as a quality attractive factors that significantly affects the satisfaction of TV based shopping customers through previous studies. The results showed that the TV-based shopping customers are important to think ‘Responsive’, ’Playfulness’, ‘Live broadcast’, ‘Convenience’ and ‘Bidirectional’ in the order. The ‘Responsive’ and ‘Live broadcast’ of such attributes are served as possible only in TV home shopping, because these attributes don’t service due to legal and institutional regulations in T-commerce market. The cluster analysis result also showed that TV shopping consumers are more important to think ‘Responsive’, ‘Playfulness’, ‘Live broadcast’ than ‘Convenience’ and ‘Bidirectional’, except one of the classification clusters. If real-time broadcast service is impossible because of the legal and institutional regulations, it seems to require the expansion of the services linked the terrestrial broadcasting to the activating T-Commerce market.

A head lamp of automobile is a very important part not only performing main function but also determining the entire design of car. However it has a chronic problem that the moisture is condensed on the inner surface of lens because of the temperature difference between the interior and exterior of the surface. Although this event is a natural phenomenon, drivers think that it is the problem of quality. TRIZ, the 'Theory of Inventive Problem Solving', gives engineers various useful tools and these tools help them to solve problems systematically. Especially, RCA and Function Analysis is useful to define problems and contradictions. In addition, TRIZ tools such as Inventive Principles, Su-Field Analysis and Standard Solutions help us to generate creative solutions to eliminate of moisture in the head lamp.

이지은(Ji-Eun Lee),신민수(Minsoo Shin) 한국IT서비스학회 2012 한국IT서비스학회지 Vol.11 No.1

Machine-to-Machine(M2M) refers to technologies allowing both wireless and wired systems to communicate with other devices. The enhancement of wireless technologies and the reduced cost of wireless connection have contributed toward the development of M2M market. M2M market currently focuses on public sector services, As M2M can offer scalable and flexible services, M2M services are expected to be applied in various fields. However there are still some doubts on whether the demand for M2M services will be increased. This study investigates the feasibility of M2M services from the perspective of operators. Operators evaluate that M2M services will show high marketability but low profitability in general. In addition, operators predict that M2M services will show both marketability and profitability in the area of car maintenance, insurance, telematics, home and office security, shop floor maintenance, and real-time locating services for children protection. This study may offer some ideas of M2M business models based on empirical feasibility studies.
