The study was performed to measure structural relationship among service value, brand image, and royalty of patients in regional public hospitals in Korea. Based on the analysis, the study aims to establish strategic direction of the regional public hospitals. Through a review of related literatures, measurement variables were identified, and a path model was developed for the study. Five regional public hospitals were chosen, and questionnaire has been collected from 387 outpatients and 358 inpatients. The study found that service value has a positive direct effect on brand image, and brand image has a positive direct effect on loyalty. Based on the findings, it is desirable for the regional public hospitals should mange the issues with lower level of perception and those with bigger effect, and establish low pricing strategy with improving the quality of service they provide.

Background: The use of therapeutic materials based on new health technology has increased in recent years in the field of medicine, raising concerns for medical practitioners regarding increased spending on the new therapeutic materials amid the rapid population ageing and increase of chronic diseases in Korea. While therapeutic materials have significant importance in the health care system, they have not been given appropriate attention in the academic world of Korea. The purpose of this study is to identify factors that affect the growth of expenditure on therapeutic materials and to derive implications for an effective management considering the diversity of therapeutic materials. Methods: Using the claims data of the National Health Insurance Services, specific utilization patterns of groups of therapeutic materials in the middle classification level of Health Insurance Review and Assessment Service from 2007 to 2014 were analyzed. Four categories (J5083: drug eluting coronary stent, D0302: nonmetallic anchor, K6014: gauze, K6023: gauze) that exhibit unique patterns with respect to price and volume were selected. Then, decomposition analysis was performed to identify the largest contributor to the spending growth by dividing the products into existing, new, and abandoned products for the period between 2010 and 2013. Results: The effect of new products had larger impact on spending growth than the effect of core items in drug eluting coronary stent (J5083) and nonmetallic anchor (D0302). In addition, existing products in general included items priced relatively lower when compared with another item manufactured by the same company. In the gauze category, however, existing products had the largest impact on expenditure and the effect of volume was greater than that in other categories. Conclusion: This study provides evidence that appropriate management measures classified by the characteristics of therapeutic materials are required for therapeutic materials pricing and reassessment in Korea.

The copyrights of music in Korea have been placed under the supervision of the associations which the government approved as a trusteeship. Since the industry of music in Korea has been changed from phonographic industry to on-line music service, it is required increasingly that the rights and interests of music should been protected. Korea government has been announced the amendment for levy of music royalties through on-line service according to the changes in the music industry and industries' demand. In this paper, the corporate structures in music industry has been investigated from the point of owner of copyright, recently at the heart of the debate, flat rate system and usage-based pricing in on-line music market has been compared. Consequently, the reasonable prices of music service through on-line market are not earmarked in reality for both consumers and copyright proprietors. Therefore, it is still necessary to improve the institutional.

Telecommunication cost have been increasing successively in Korean hoseholds and its level is high now. Even though here are a lot of issues related to the high bill of mobile telecommunication services, plausible solutions have not been provided yet. 99% of Koreans use mobile phones and it is the highest rate in the world, but bill is relatively high. This situation may be brought by the government policy selection that it supports three mobile telecom companies systems. Thus least efficient company should be supported to sustain by pricing policy and MVNO cannot come into the market. The government can make mobile pricing system consider revenue and cost only in proper manner and constrain marketing cost in the rational level. And it can reduce mobile bill levels and selection rights of consumers by restraining too much complicated bill system. Fairness of mobile phone bill levels could be achieves by mobile telecommunication structure improvement through active MVNOs and reduction of excessive marketing costs. Mobile bills can be made more acceptable if the base is measured rate system.

In this paper, a new mathematical scheme of Macro Handover Management (MHM) in F-HMIPv6 networks based on Location Based Services (LBS) is proposed. Previous schemes based on F-HMIPv6 protocol usually suffer from three major drawbacks: First, They don't exploit the information about the user mobility behavior in order to reduce handover effects. Second, they only focus on the micro mobility level. Third, they don't consider the quality of service (QoS) of the traffic. The proposed MHM scheme avoids these drawbacks using the available information about Mobile Node (MN) such as user mobility patterns and MN's velocity to predict handover and improve network's QoS. It also takes the traffic type in consideration since it presents a major factor in locating QoS for the user. MHM is analyzed and compared with the F-HMIPv6. The results show that MHM improves the performance in terms of packet delivery cost, location update cost, and handover latency. The design of MHM comprises software package in the MN in addition to a hardware part in the network side. It has implications for communication, design, and pricing of mobile services.

Objectives : The aim of this study was to investigate the effect of various Republic of Korea policies, including the medicine cost rationalization policy implemented By investigating the management strategy/performance changes of the industry caused by such policies. Methods : Pharmaceutical companies listed on the national stock exchange and the KOSDAQ were examined for 10 years from 2004 to 2013. Their financial statements were collected and market changes before and after drug price policy implementations were compared. Results : From the result of this research, among the medicine related policies, the drug price rationalization policy was found to have a significant effect on business management strategies in terms of safety, profitability and growth potential after its implementation. After the drug pricing transparency policy was implemented, management strategies were affected significantly in terms of safety and profitability. Conclusions : As a result, all of the medicine related policies were found to have regulatory effects. Based on these findings, implications, research limitations and future study plans are presented.

Purpose - This study proposes a framework for service innovation strategy to cope with the emergence of electric vehicles. Research design, data, and methodology - This study designs an electric-vehicle lease program and collects the resulting data to analyze. By analyzing the previous studies on the electric-vehicle market with cases, a theoretical framework based on existing theories is to be set. Results - This study proposes a strategy for the rapid diffusion of electric vehicles. First, a partitioned-pricing system is proposed to create an advantage for electric vehicles in terms of initial purchasing cost relative to traditional internal combustion vehicles. Second, focusing on reducing switching costs is important because electric vehicles have relatively low resale values due to the uncertainty of battery life. Third, a battery-leasing strategy is supposed to reduce the cost of switching from a traditional internal combustion vehicle to an electric vehicle. Conclusions - This paper can provide strategic guidance for decision makers in firms that have already entered the electric-vehicle leasing market by making a recommendation such as a service innovation strategy. The proposed strategy can be considered as an electric vehicle market in the future and can contribute to the wider diffusion of electric vehicles.

The purpose of this study was to investigate the influence of customers' perceived risks on their perception of value at family restaurants in Seoul. Frequency analysis, reliability analysis, factor analysis, multiple-regression analysis were employed to analyze the data. The customers' perceived risk were divided into 6 factors. Three of the perceived risk factors(financial, time, performance risk) negatively(-) influenced the perception of value. In particular, 'financial risk' was the most negative. However, 3 factors(physical risk, psychological risk, social risk) didn't have significant influence on perceived risk. As a result, customers of family restaurants appear to perceive various risks, and these risks have significant impacts on their perception of value. Therefore, food-service corporations need to reduce customers' perceived risks, possibly by various and efficient pricing-policies, discount, price-bundling, using coupon, effective physical evidence and offering unique compensation.

Device-to-device (D2D) communications underlaid cellular infrastructure is an competitive local area services technology to promote spectrum usage for next generation cellular networks. These potential can only be tap through efficient interference coordination. Previous works only concentrated on interference from D2D pairs whiles interference from CUs to D2D pairs were neglected. This work focus on solving uplink interference problem emanating from multiple CUs sharing its resource with multiple D2D pairs. The base station (BS) acting as a supervisor selfishly institute a pricing scheme to manage the interference it experience from D2D pairs based on its Quality of service (QoS) requirement. D2D pairs following the supervisor make power allocation decisions considering the price from the BS in a non-cooperative game fashion. In order for the D2D pairs to also meet their QoS requirement, they suggest a price to the BS called discount price which reflects the interference they receive from the CUs. Finally, we analyze the proposed approach.

In the near future packet networks should support applications which can not predict their traffic requirements in advance, but still have tight quality of service requirements, e.g., guaranteed bandwidth, jitter, and packet loss. These dynamic characteristics mean that the sources can be made to modify their data transfer rates according to network conditions. Depending on the customer&; needs, network operator can differentiate incoming connections and handle those in the buffers and the interfaces in different ways. In this paper, dynamic QoS-aware scheduling algorithm is presented and investigated in the single node case. The purpose of the algorithm is in addition to fair resource sharing to different types of traffic classes with different priorities ?to maximize revenue of the service provider. It is derived from the linear type of revenue target function, and closed form globally optimal formula is presented. The method is computationally inexpensive, while still producing maximal revenue. Due to the simplicity of the algorithm, it can operate in the highly nonstationary environments. In addition, it is nonparametric and deterministic in the sense that it uses only the information about the number of users and their traffic classes, not about call density functions or duration distributions. Also, Call Admission Control (CAC) mechanism is used by hypothesis testing.
