In this Paper, we propose a method of determining the price for the elastic traffic in the current or future Internet services. First, we investigate the behavior in the consumption of bandwidth of elastic traffic in IP network. Next, we propose a new method to relate the bandwidth usage with the pricing for the elastic traffic, which is based partially or fully on the usage rate of the network bandwidth. Next, we propose an optimal charging function for elastic traffic, which is applicable to any Internet services. Finally, we will illustrate the implication of the work via simple numerical experiments.

In this paper, the authors propose methods for determining the differentiated price for elastic traffic in IP (Internet Protocol) network. First, we investigate the behavior in the consumption of bandwidth of elastic traffic in IP network. Next, we propose a method to relate the bandwidth usage with the pricing for the elastic traffic, which is based partially or fully on the usage rate of the network bandwidth. After that, we propose a charging function for elastic traffic, which is based on the de facto usage of the bandwidth. Finally, we will illustrate the implication of the work via simple numerical experiments.

In this work we propose a new pricing scheme for the wireless Internet services over WiMAX system. First, let us review the characteristics of wireless network which is based on multi-hop relay WiMAX system. Next, we show why usage-based and QoS-aware pricing scheme is needed in the wireless Internet. After that, we propose a theoretical model for the price of multimedia services called a DAP (DiffServ-aware pricing) scheme for the WiMAX multimedia network which takes into account the consumed radio resource of WiMAX system as well as the supported QoS in the IP backbone network. Finally, we present explicit formulae for the packet price, price of consumed radio resource, and price of consumed bytes.

3년이 넘게 진행되었던 SK와 넷플릭스 간 분쟁은 소송을 취하하고 양사가 협력 관계를 맺는 방향으로 일단락되었다. 하지만 디지털 대전환, 생성형AI 활성화 등으로 인해 인터넷 트래픽 이용량은 향후 더욱 늘어날 가능성이 있어 망이용대가를 둘러싼 국내 이동통신사와 글로벌 CP 사업자간 갈등은 언제든지 다시 발생할 수 있다. 본 연구에서는 SK와 넷플릭스 사이에 발생했던 망이용대가와 관련된 분쟁의 쟁점을 살펴보고 각 쟁점에 따른 함의를 도출했다. 망이용대가의 유상성 및 범위는 전적으로 사업자 간 협상에 의해 결정되어야 하는 사안이다. 다만, 사업자 간 분쟁이 발생하게 되면 속도 지연 등 이용자의 피해가 발생할 수 있으므로 이에 대한 정책적 대안에 대한 검토가 필요하다. 국내 미디어 산업은 글로벌 CP와 협력적으로 성장해 온 측면이 있어 향후 망이용대가와 관련해 국내 이동통신사업자와 글로벌 CP 사업자 간 호혜적인 관계 형성이 중요하다고 판단된다. 하지만 사업자간 상생을 위해서라도 향후 발생할 수 있는 갈등을 중재할 수 있는 대안에 대한 학술적 검토는 이뤄질 필요가 있다.

This paper introduces a sequential clustering technique as a tool for an effective grouping of transmission systems. The interconnected network system retains information about the location of each line. With this information, this paper aims to carry out initial clustering through the transmission usage rate, compare the similarity measures of regional information with the similarity measures of location price, and introduce the techniques of the clustering method. This transmission usage rate uses power flow based on congestion costs and similarity measurements using the FCM(Fuzzy C-Mean) algorithm. This paper also aims to prove the propriety of the proposed clustering method by comparing it with existing clustering methods that use the similarity measurement system. The proposed algorithm is demonstrated through the IEEE 39-bus RTS and Korea power system.

The purpose of this research is to identify what factors influence a customer's purchasing intention and to identify if customer's attitudes are different between an Internet shopping mall in Singapore and Korea. To perform a cross-nation analysis between Singapore and Korea, this research reapplied the finding of Liao and Cheung(2001) in a Singapore Internet shopping mall, including transactions security, Internet usage, price, shopping experience, vendor quality, network speed. The empirical results of this research indicate that all hypotheses in our model are significant; therefore, Internet usage, price, vendor quality and network speed influence customer's purchasing intention positively and transactions security and shopping experience negatively. The results of a cross-nation analysis indicate that customer's attitudes in both Singapore and Korea are the same. Therefore, Asia's with similar cultures are the same factors In Internet shopping mall. In Conclusion, with the rapid growth of the Internet market in Asia, many cross-nations researches based on Asia culture must be published. Therefore, this research will be the foundation of these researches.

This paper introduces the method of sequential clustering as a tool for the effective clustering of mass unit electrical systems. The interconnected network system retains information about the location of each line. With this information, this paper aims to carry out initial clustering through the transmission usage rate, compare the results of similarity measures for regional information with similarity measures for regional price, and introduce the technicalities of the clustering method. This transmission usage rate used power flow based on congestion costs and modified similarity measurements using the FCM algorithm. This paper also aims to prove the propriety of the proposed clustering method by comparing it with existing clustering methods that use the similarity measurement system. The proposed algorithm is demonstrated through the IEEE 39-bus RTS.

Expansion and enhancement of information and communication infrastructure can create a market closer to an ideal type for a perfect competition, utilizing a cyber space in the network (with the expanded usage of Internet and e-commerce) and it could be a market of a monopolistic form. The government can take one of the two approaches responding to this monopolization of the digital market. First, the government maintains laissez-faire policy since the monopoly cannot be maintained over a long period of time due to an increasing in the production, decrease in the price, profit resulting from this and rapid technology evolution. Second, the government can actively interrupt the monopolization of the digital market. Monopolization in a digital market can lead to a market failure. Unstable market structure and too much frequent merger and acquisition contribute to making the digital market very dynamic. Information goods exchanged in the digital market have the features of very low marginal cost required to copy the original product whereas its initial fixed cost is very high. This explains why the information products are not priced based on the existing marginal price determination principles and why companies producing them have various product sales strategies (price/product differentiation strategy, and other sales strategies).

본 연구는 콘텐츠 제공자를 포함한 플랫폼 사업자가 광대역 인터넷 접속을 통해 고품질의 콘텐츠를 제공하는 경우 보편적 서비스 기여금을 분담할 때 이것의 경제적 효과를 분석한다. 주요 결과는 다음과 같다. 첫째, 플랫폼 사업자가 독점적 위치에 있다면 트래픽 이용량은 사회적 최적 수준보다 적으며, ISP가 결정하는 가격들은 콘텐츠 수요의 가격민감도에 영향을 받는다. 둘째, 플랫폼 사업자가 경쟁적인 경우 ISP가 책정하는 요금은 사회적 최적 수준과 동일하다. 셋째, 플랫폼 사업자가 콘텐츠 요금을 부과하지 않는 경우는 ISP는 요금을 사회적 최적 수준으로 결정하고 광고 수입이 많을수록 소비자에게 부과하는 망 이용대가는 줄어든다. 이는 플랫폼 사업자에게 고품질 콘텐츠 서비스를 제공할 수 있는 네트워크 서비스를 이용하는 대신, 보편적 서비스 기여분 분담을 의무화한다면 사회후생은 증가될 수 있기 때문에 플랫폼 사업자에게 보편적 서비스 기여분을 분담하는 것이 사회적으로 바람직하다는 것을 시사해 준다.

The popularity of the social media has enabled growth of the social network, which has a big impact on culture and arts sector. The impact is based on the fact that news and evaluation of performances are communicated actively through the use of on-line community, and that the advent of social commerce makes more people see better performance at a lower price. Besides, collaboration programs called Social Sourcing are springing up in the arts sector, and there is Crowd Funding for culture & arts which is a desirable form of social funding. In this way social media and social network service (SNS) have huge social influence not only on the performing arts sector but also on the whole culture and arts sector, and are expected to have growing dominance. With SNS - which opened new marketing, publicity and donation system not only for the whole society but also for the culture and arts sector - in mind, this paper handles the topics on understanding of close relationship between SNS and performing arts, and on its current usage, value and endless possibilities. By presenting the practical value and the possibilities, this paper will help in making smooth the communication between stakeholders and audience of performing arts, in making effective the means of performance delivery, and in making enlarged the mutual understanding between performers and audience. This paper will also be the basis of an alternative means, which presents the performing arts sector with possibilities to get out of the chronic deficit.
