The purpose of this study is to compare and analyze the relationship among image, customer satisfaction and loyalty of fashion Extension brands. It is expected that this study will provide guidance to fashion companies that are planning to expand their brand in setting up marketing strategies and service strategies. The results of the study are the following. First, women consumers in their 20s had an perception that second brands provided diverse and unique products at cheap prices. However, after purchasing the products, they recognized that the second companies' service level was not so satisfying. Second, consumers were satisfied with the brand awareness, reputation, image, design, color, and packing conditions of the second brands while being not satisfied with the pricing. Third, when the study examined brand loyalty of second brands, consumers have shown high loyalty to the four subsidiary brands. Fourth, the satisfaction level for the four second brands had a significant effect on the brand loyalty for each second brands.

This research was conducted to estimate the use and preservation values of Jirisan national park, using a dichotomous choice contingent valuation. Jirisan national park was estimated to have the use value of 6,377 won per visitor. In terms of preservation value was estimated 13,030 won per housed per year. The results of this research show that Jirisan national park generated considerable use and preservation values, exceeding far greater than current admission fees. The findings also indicate that the estimated economic value provides enough justification for the national park service to increase admission fees in order to maintain the quality of the natural environment. This result may contribute to guidance on the pricing policy of national park managers and practitioners, although public policy may be made in the political arena.

클라우드 서비스를 위한 가격결정은 서비스 제공자 중심의 정책으로 수립되어 가장 큰 이익을 줄 수 있는 모델로 제안되고 있다. 하지만, 클라우드 서비스 브로커 개념의 등장으로 서비스 중개 방식을 이용하여 서비스 제공자와 소비자 모두에게 이익을 줄 수 있는 모델을 제공하고자 노력하고 있다. 이와 같은 노력에 있어 가격결정 정책에 대한 분석을 수행하고 그를 만족할 수 있는 모델을 제안한다. 클라우드 브로커가 사용자의 서비스 미사용량과 SLA를 기반한 서비스 품질을 기준으로 환불 등의 서비스를 제공하는 모델이다. 이와 같은 모델은 클라우드 서비스 활성화에 큰 도움이 될 것으로 기대된다.

We are concerned with whether a vertically integrated broadband and content provider can unreasonably advantage itself over competing content providers, either by selling quality-of-service (QoS) to content providers at unreasonably high prices, or by refusing to provide access to QoS to competing content. We address this question by modeling the competition between one such vertically integrated provider and one over-the-top (OTT) content provider. The broadband provider decides whether to deploy QoS, and if so it also determines the QoS price if sold to either the OTT content provider or directly to users. We analytically determine when the broadband provider will sell QoS and when the OTT content provider or users will purchase QoS. We characterize the optimal QoS and video service prices. The Internet service provider (ISP)'s market share increases with the difference in the value of the two video services and decreases with the difference in the corresponding costs. Numerical results illustrate the effect of QoS price on content price, the variation of prices and profit with QoS price, and the variation of prices and market shares with the benefit of QoS. The ISP may sell QoS to users at a lower price than when QoS is sold to the OTT provider.

For the power system to keep in a stable operating state, sufficient ancillary services must be available to respond to credible contingency events and return the power system to a satisfactory operating state in the case of contingencies as well as blackout events within specified predefined limits. The logical and reasonable bases of valuing and pricing the ancillary services are required to reach the common ground among market participants. The total amount of black start service transactions is quite small compared to the total ancillary service transactions as well as energy market transactions. Black start services must be provided as one of the ancillary services in the deregulated electricity market. In order to procure and remunerate black start services, it is necessary to quantify the value of the black start sources within the power system. In this paper, an approach to assess the value of the black start service is presented based on the cost-of-service solution. Financial simulation of the influence on market participants for the proposed approach on the service is carried out. The cost of the black start service is allocated in accordance with the principle of "causer pays", and the cost is shared by the producers and consumers equally that created the requirement for the service. Under the present electricity market, the mechanism to recover the cost is not implemented, a new approach to the ancillary services to provide incentive for the service providers has to be studied in the near future.

Any server offering a routing service in the Internet would naturally be in competition for clients, and clients may need to utilize service from a specific server in order to achieve a desired result. We study the various properties of this competition, such as the fraction of route requests handled by a routing service provider and the fraction of total revenue obtained. As the routing service providers (i.e., servers or routers in this context) compete, they may alter behavior in order to optimize one of the above properties. For example, a service provider may lower the price charged for its service, in order to increase the number of clients served. Our models are based on servers offering a routing service to clients within representative network topologies based on actual Internet sub-graphs. These models provide, a framework for evaluating competition in the Internet. We monitor key aspects of the service, as several variables are introduced into the models. The first variable is the fraction of client requests that will pay more for a better quality route. The remaining requests are normal client requests that are satisfied by the most economical route. The second variable is the fraction of servers who choose to lower service prices in order to maximize the number of client requests served. As this fraction increases, it is more likely that a server will lower the price. Finally, there are some resource constraints applied to the model, to increase the difficulty in providing a routing solution, i.e., to simulate a realistic scenario. We seek to understand the effect on the overall network, as service providers compete. In simple cases, we show that this competition could have a negative impact on the overall efficiency of a service. We show that the routing variety present in the larger models is unable to mask this tendency and the routing service performance is decreased due to competition.

This study was undertaken to provide basic data for revitalizing the school meal support centers and improving school meals, by analyzing the purchase conditions and satisfaction of food according to an adoption of a school meal service support center. Comparing the purchasing efficiency, convenience to purchase, and higher overall satisfaction was achieved when a school meal service support center was adopted by the local government, as compared to non-adopted school meal service support centers. Therefore, it is considered that the adaption of a school meal service support center is urgently required by non-adoption local governments. Moreover, the stability of food material supplies was also higher in the adopted rather than the non-adopted centers. Satisfaction with the quality of food ingredients was also found to be significantly higher in the adopted centers. These results indicate that if the local government adopts and introduces the school meal support center, inconsistencies observed in the return and exchange processes experienced by the non-adopted centers can be resolved, and food quality satisfaction can be improved. We, therefore, propose the necessity to implement a system for determining reasonable pricing by establishing systematic cooperation among schools, manufacturing entities (suppliers), and the School Meal Service Support Center.

Restaurants have two strategic levers for revenue management: duration control and demand-based pricing. Reducing dining times, especially during peak periods, can add considerable revenue for restaurants. Managing meal duration, however, can be far more complex than manipulating the price. This paper examines dining duration expectations for restaurants types(Family, Korean, Quick service restaurant), customers characteristics(gender, age, occupation, meal period, visiting frequency, dining occasion, dining companions) using an a adaptation of a price sensitivity measurement tool, naming it 'Time Sensitivity measurement tool' or TSM. The TSM is then used to derive the optimal time points, and the range of acceptable times. The results demonstrate that there is a relatively wide spread of acceptable dining duration times in family restaurant. Furthermore, the optimal time points was shorter than the mean expected dining times, which suggests that many restaurants may be able to shorten dining duration without compromising customer satisfaction. The paper explores whether demographic and dining variables have an impact on time preferences, and finds whether gender, age, meal periods, visiting frequency, and dining companion effects are significant. Specifically, women in their thirties tended to prefer a significantly longer dining times for dinner.
