In this paper, we deal with a new techno-economic modeling and analysis for optical access networks. In deploying the fiber-to-the-home (FTTH) architecture, network planner needs to consider the following techno-economic issues: when do we need to upgrade existing local access network to FTTH network? how much do we invest to maximize profit? In order to answer these techno-economic questions, we need to consider the impact of emerging technologies and business environment. Toward this end, we develop a new techno-economic modeling to deal with the inherent complexity of technology evolution and cost economics. In particular, the new modeling approach provides us with an techno-economic analysis of technology alternatives such as ethernet passive optical network (E-PON) and wavelength division multiplex passive optical network (WDM-PON). In this analysis, we focus on the impact of critical factors such as the cost characteristic of proposed architecture and digital subscriber line (DSL) subscriber's churn-in to FTTH service and churn-out. We develop mixed integer-programming models for finding the evolution path of local access networks to broadband network architectures.

The most presentative case would be functional evolution of webtoon as a contents business model, which has taken a initiating role in both innovated strategic experiments and outcomes. Most of all, There are the launch of PPS(Page Profit Sharing) sevice in NAVER webtoon, the paid service model implementation in KAKAOpage and potential business as an exclusive application in Lezhin entertainment This study to analyze these phenomina and results can figure out how the business model in the webtoon platform is developed in various fields diversely and what makes this model evolved and extended. Especially, the diversification of the webtoon platform has been received attention since it pursued the grouped spin off through horizontal convergence and transformational expansion among similar platforms, and also this shows that which factors enhance these phenomina to be controled and expanded. On the basis of the result of this study, we try to find the way to connect business vision of the domestic webtoon platform with affiliated business. Furthermore, it proposes the interrelationship between this and the business strategy for overseas in the globalized platform.

급속한 기술환경의 변화와 정보화 사회의 도래에 따라 시스템의 구축 비용보다 더 많은 비용이 유지보수에 투입되고 있다. 소프트웨어의 생명주기 측면에서 40-90%의 큰 비중을 차지하는 유지보수를 효율적으로 관리하는 것은 매우 중요한 문제이다. 이에 본 연구에서는 비즈니스 어플리케이션의 운영관리에 관한 사례를 유지보수 유형에 따라 분석하고, 이를 바탕으로 변경 관리의 개선 방향을 제시하였다.

Artificial Intelligence has been a conceptual area for several decades. It has been studied extensively through experiments by the Information Systems community. When Information Systems supported with Information Technology became all pervasive in business and other allied areas, gradually the advancements in Artificial Intelligence also emerged as innovations across domains. Artificial Intelligence by definition is expected to substitute Human Intelligence, thereby making a huge space for innovation. In fact, all processes effected by human intelligence are liable to be replaced by AI which in itself is a massive innovation space. This paper will study the publication's repository (Scopus and Google Scholar from 1983 till 2021) in the area of Artificial Intelligence and innovation, then analyze the trend to gain insight into the evolution of AI as a vehicle for innovation.

IT evolution and the e-business has emerged as a new economic activity and beyond the time and space limitations. But the enterprises located in GangWon-Do area have been too inactive in their willingness and readiness to adopt e-business models and processes owing to the lack of the directions of e-business, the insufficient network infrastructures and capitals, etc. In this circumstance, as part of this research, this papers have conducted a survey on the e-business and information conditions and status among the enterprises located in GangWon-Do Chuncheon area. In conclusions, this study on the informatization of the enterprises and e-business enlarge strategies for building competition of local enterprises located in GangWon-Do Chuncheon area.

In this paper, we develop the business model of telecommunication company that facilitates to explore new business opportunities on aging society. Considering the trend of aging society, we analyze the market drivers of senior market. Analyzing market dynamics and value chain, we design a set of business models for telecommunication company. In addition, we describe the evolution path of the proposed business model in terms of technology development and market. Finally, we develop a framework for evaluating the effectiveness of the business model.

To reduce time to market for converged services, the service provider needs to combine external services and internal processes together, and IT architecture for converged services has to support it. Service Oriented Architecture (SOA) enables the development of a converged service by combining external services and internal processes effectively. However, it is difficult for the existing SOA methods to support the evolution of a converged service, even though the service which consists of the converged service changes over time. In this paper, we argue that a method for profile-based dynamic service binding is required to support evolution of converged services. In order to identify requirements for the proposed method, a business scenario with a smart athletic equipment is given. We then present the concept and architecture of the method for profile-based dynamic service binding to meet the identified requirements. We also demonstrate a prototype implementation for evaluating the proposed method.

Many markets are forecast to see significant changes due to the growth of electronic commerce made possible by the internet. The way of doing business with internet affects the market mechanism. It is now over 10 years since Malone et al(1987) set out their hypothesis on electronic markets, and electronic hierarchies. An electronic market is an interorganizational information system through which multiple buyers and sellers interact to accomplish one or more of the following market-making activities. And they predicted that markets evolve toward electronic markets, by reducing search cost, which may result in significantly. higher price competition among sellers and therefore lower prices for buyers. And the degree of two factors; asset specificity and uncertainty, affect the market mechanism. Products with low asset specificity and low uncertainty are compatible with a market relationship while the greater the asset specificity and uncertainty, the more likely it is to favour a hierarchical structure. Based on the these researches, we observed and analyzed a case study of market mechanism in Internet business. We found the fact that even though Internet could make the business environment in which lots of buyers and suppliers participate, electronic market will evolve market mechanism. 1 analyzed two factors, which affected market evolution. First, When Asset specificity is low in electronic commerce, market structure should be preferred to hierarchical structure. Second, When transaction uncertainty is low in electronic commerce, market structure should be preferred In hierarchical structure. This research covers conceptual and empirical aspects on electronic market structure. Future research should be variously done about the influential factors of electronic market mechanism.

This paper presents a new approach for thermal unit commitment (UC) using a differential evolution (DE) algorithm. DE is an effective, robust, and simple global optimization algorithm which only has a few control parameters and has been successfully applied to a wide range of optimization problems. However, the standard DE cannot be applied to binary optimization problems such as UC problems since it is restricted to continuous-valued spaces. This paper proposes binary differential evolution (BDE), which enables the DE to operate in binary spaces and applies the proposed BDE to UC problems. Furthermore, this paper includes heuristic-based constraint treatment techniques to deal with the minimum up/down time and spinning reserve constraints in UC problems. Since excessive spinning reserves can incur high operation costs, the unit de-commitment strategy is also introduced to improve the solution quality. To demonstrate the performance of the proposed BDE, it is applied to largescale power systems of up to 100-units with a 24-hour demand horizon.
