The purpose of this study is to review the theories and cases of performance sharing in the franchise industry to present a method for more effective franchise performance-sharing. To that end, this study reviewed the theory on resource dependence and the theory on inequality to describe the performance-sharing between the franchisor and the franchisee and their relationship. It also looked at the cases of a week-in cooler system at 'Beer Market', the allocation of fees for alcoholic beverage sales to franchisees, the scholarship program of 'Onigiri and Ikyudon' and 'Bonsamo' which is a franchisees' committee for Bonjuk to introduce examples of performance-sharing. Through a theoretical review and case review, this study presents five types of methods for performance-sharing. First, 'the sharing of core competence by the franchise company; second, 'the establishment of a royalty culture'; third, 'scientific analysis of markets and establishment of a revenue forecast system'; fourth, 'reinforced financial support from the franchisor'; and lastly, 'the positive application of franchisees' committees'. Such methods are expected to provide a groundwork for mutual benefit and co-prosperity between franchisor and franchisee.

The term 'Grid' refers to systems and applications that integrate and manage resources and services distributed across multiple control domains. Resource sharing is, necessarily, highly controlled, with resource providers and consumers defining clearly and carefully just what is shared, who is allowed to share, and the conditions under which sharing occurs. In this paper, we design and implement a grid access control system, called PGAM. This system works on heterogeneous resources, can be applied to the additional service development and its service, provides template account management mechanism, and tries to ensure site autonomy. This system is implemented to increase portability and to be tit tll any kind of economic model.

Demand of spectrum resource is tremendously increasing and this trend will continue as more IT services such as cloud computing, smart devices, Internet of Things are provided through wireless network. Recent development of spectrum sharing technology has drawn attention to spectrum policy makers as a promising way to overcome the expected spectrum shortage problem. However, technology-based solution to spectrum shortage problem may not be sustainable since the solution affect only one aspect of spectrum sharing ecosystem. To understand the whole picture of spectrum shortage problem, policies to vitalize spectrum sharing ecosystem were proposed based on the analysis of System Dynamics causal map in the previous study. This study compares and analyzes the effect of those proposed vitalization policies by using System Dynamics simulation. Among seven alternative policies, combined application of demand acceleration policy and technology development policy was found to be more effective for better utilization of spectrum. The effect of demand acceleration policy was offset when other policies are applied together except supply acceleration policy which shows better spectrum sharing.

The scalability of a grid system should be efficiently designed to handle the increasing number of grid users. This paper presents a scalable resource sharing mechanism among virtual organizations (VO) in grid environment by the scalable virtual organizations (SVO). The proposed grid architecture is composed of standard services of a grid system to manage the SVO. We propose a group similarity function which is used to determine similarities among VOs to select the VOs to merge. We compared other similarity functions to the GSF and determined the throughput performance of the SVO using simulation for grid system.

In this paper, we studied on the building models of open educational resource service system for download or upload their own educational content to be shared with the others without worrying about copyright infringement. We first analyzed the building models of the international OER(Open Educational Resource) service sites. And then, based on these results, we present the new service models suitable to be built the open educational resource service system in phases. The proposed models have the flexibility to accommodate the needs of users and have the advantage that the copyright-related issues of the existing 'National Educational Information Sharing System' could be solved step by step.

In the context of effective usage of a scarce spectrum resource, emerging wireless communication standards will demand spectrum sharing with existing systems as well as multiple access with higher spectral efficiency. We mathematically analyze the sum throughput of a spectrum sharing space-division multiple access (SDMA) system, which forms a transmit null in the direction of other coexisting systems while satisfying orthogonal beamforming constraints. For a large number of users N, the SDMA throughput scales as log N at high signal-to-noise ratio (SNR) ((J-1) loglog N at normal SNR), where J is the number of transmit antennas. This indicates that multiplexing gain of the spectrum sharing SDMA is $\frac{J-1}{J}$ times less than that of the non-spectrum sharing SDMA only using orthogonal beamforming, whereas no loss in multiuser diversity gain. Although the spectrum sharing SDMA always has lower throughput compared to the non-spectrum sharing SDMA in the non-coexistence scenario, it offers an intriguing opportunity to reuse spectrum already allocated to other coexisting systems.

It is very difficult to construct and manager public transit, like subway, in small city. In this paper, we suggest full electric vehicle sharing service framework as a public transit system in small city. The suggested system will reduce environment pollution and increase resource usage efficiency. The simulation result shows that the suggested electric vehicle sharing system can reduce traffic congestion and lower city road stress.

Efficient spectrum sharing is an important issue in Device-to-Device (D2D) communications underlaying cellular networks as it can mitigate the interference to cellular users and improve the performance of the systems. In this paper, we formulate the radio resource allocation in D2D communications as a mixed nonlinear integer programing. We show the formulated problem is NP-hard and thus a polynomial time algorithm to solve is not possible. Since such a problem is very hard to obtain the optimal solution within a short running time, we instead propose a fast heuristic suboptimal algorithm to mitigate the interference caused to cellular users and improve the performance of the systems. Simulation results are provided to evaluate the performance of the proposed algorithm.

Korea, China and Japan are in great demand for each other’s science and technology information since they geographically lie adjacent and have common interest in a variety of science and technology fields. Yet, they have difficulties in obtaining the other two countries’ information due to the lack of an appropriate system to access the information and also to restrictions such as a language barrier. The purpose of this study is to suggest the ways of sharing science and technology information among Korea, Japan and China. It surveys the national science and technology information systems and policies of each country and proposes four stages of resource sharing.

In this paper, we introduce an adaptive radio resource allocation for IP-based mobile satellite services. We also present a synchronous multibeam CDMA satellite system using an orthogonal resource sharing mechanism among downlink beams for the adaptive packet transmission. The simulation results, using a Ka-band mobile satellite channel and various packet scheduling schemes, show that the proposed system and resource allocation scheme improves the beam throughput by more than two times over conventional systems. The simulation results also show that, in multibeam satellite systems, a system-level adaptation to a user's channel and interference conditions according to user locations and current packet traffic is more efficient in terms of throughput improvement than a user-level adaptation.
