What is the starting point of discussions for the open access of Korean journals? This study analyzed whether the serials crisis in Western societies are in academic libraries in Korea. The rising of prices of Korean electronic journals in academic libraries and recognition of librarians for it were surveyed. This study found that the subscription fees for web DBs of Korean journals have been increased from 1.3 times to 34 times during the last 10 years. But librarians in the universities did not think that the subscription fees are very high. And the 35% of respondents thought that the subscription fees for the web DBs in academic libraries will be increased to bring to a crisis to libraries. This study suggested that the leading groups of discussions for open access in Korea wilt be interested in the aspects of public goods and social justice, another values of open access.

The purpose of this study is to understand the impact of the subscription economy on the contemporary art market in terms of creation, consumption and distribution of artwork. To accomplish the aim of this study, we conducted a case study of Artnomic Gallery K borrowing the theoretical perspective from Alexander(2003)'s Modified Cultural Diamond model. In this paper, we collected data through reviewing the secondary document and conducting in-depth interviews with 10 experts and consumers in the art market. As a result, the subscription economy eases the traditional art trade, which is heavily focused on a small number of market arts, by encouraging artists to create various works. The transition to subscription in the purchase of art contributes to lowering the barriers to entry into the art market by reducing the financial burden on consumers in terms of consumption. In terms of distribution, this founding of this article shows that the experts of Gallery K are the main actors in selecting the works that consumers subscribe to. Therefore, in this study, it is of academic significance to discuss that the filtering effect of the distribution system emphasized by Alexander(2003) is effective even in the art trading system to which a new form of economic activity - the subscription economy - is applied.

This study empirically analyzes casual relationships among psychological and financial factors influencing the subscription of individual pension and identifies mediation effect by the structural equation model. The analysis based on survey data (N=928) from common people living in the seven major cities in Korea shows that potential longevity, coping efficacy to the financial risks from longevity, subjective knowledge on longevity (cognitive factor), trust in insurers (social factor), and financial literacy(financial factor) are key players exercising direct influence over the subscription of individual pension. It also has been shown that affect on longevity, potential longevity, trust in government, and coping efficacy influence the emotions on longevity, fear and worry, and emotions on longevity are not significant in explaining the subscription of individual pension. Trust in insurers and financial knowledge of prospects have also been reaffirmed to be crucial factors in the activation of individual pension subscription.

Serials subscription prices continue to escalate but university library budgets of those have not grown concurrently at the same rate. In fact, library budgets of serials subscription have decreased as a percentage of total library expenditure. Also titles with little or no use should be cancelled to make room for new serials that might be needed to reflect new research interests or changes in curriculum. This study includes overview of the serials cancellation and substitute solutions for subscriptions in university library. Taking into account costs and coverages, availability of cancelled serials through interlibrary loan is high in general. There is a potential for considerable savings by providing access to low-use titles, and that is a combination of commercial document delivery and pay per view based on e-business could be a viable alternative to subscription in many cases.

In Korea, cable television(CATV) broadcasting has begun in March, 1995. This Paper aims at examining the location of CATV broadcasting station, and demand density(numbers of viewer houshold) of broadcasting area, and at clarifing the factors affecting subscription. The results are as follows: The number of CATV stations is 54 in 1996, and these CATV stations are mainly located in larger cities. The correlation between the number of established or planned CATV station and the number of household is very high. In sphered broadcasting area Permitted in 1997, the location of CATV station is about 73,000 household and 230,000 persons in the minimum values of household and population, and diameter of sphered broadcasting area is 40.6 km in mean. The factors affecting subscription rates of CATV are median age and supply rates of apartment of each dong in Chongju city and each myun in Chongwon county. The correlation between subscription rates of CATV and supply rates of apartment appears higher than correlation between subscription rates and median age other factors based on residual analysis of regression equation are established period of transmission network of CATV and acceptance attitude of dwellers.

In mobile Internet environment, providing multicast requires much more complex mechanism comparing with the unicast Mobile IP routing protocol. This is because multicast datagrams are sent to a group address that do not belong to a specific network. The IETF Mobile IP suggested two approaches for mobile multicasting, namely remote subscription and hi-directional tunneling. In remote subscription, a mobile node may join a group via a local multicast router on the visited subnet. Therefore remote subscription may cause much datagram loss while reconstructing the delivery tee. In bi-directional tunneling, a mobile node may join a group via a hi-directional tunnel to its home agent. Bi-directional tunneling may suffer from inefficient routing. In this paper, we proposed a new mobile multicasting protocol, Mobile If Multicast using Local Broadcast(MIMLB) which can receive multicast datagrams as fast as possible and optimize routing path for multicast delivery. The MIMLB protocol uses hi-directional tunneling to receive multicast datagrams. And the MIMLB protocol can resolve datagram duplicated problem and optimize routing path by using local broadcast. Simulation results show that MIMLB reduces delivery path length and optimizes multicast routing path when a mobile nod? moves into a foreign network.

In this paper, we study a multicast transport technique for multimedia services of mobile hosts in wireless network environments. To reduce packet loss during hand-off, we propose a Pre-join scheme in overlapped area and a Buffering scheme in crossover routers. To support seamless service in real time multimedia application, these scheme use an optimal path routing which was provided in remote subscription scheme and a prediction scheme of host movements which was considered overlapped area. To evaluate the peformance of our scheme, we compare Bi-direction tunneling of mobile If, Remote subscription, and MoM by using NS-2. As a result, our scheme shows better performance in network overhead, packet loss and bandwidth's use than other schemes.

As the OTT video service has grown, much attention has been paid to its impact on the traditional media market. This study explores how the OTT video service(measured as OTT subscription revenue, OTT advertising revenue, and Netflix effect) has impacts on the traditional media market(measured as pay TV subscription revenue, media advertising revenue, and broadcast advertising revenue), using the panel dataset with 50 countries from 2012 to 2020. For pay TV subscription revenue, OTT subscription revenue is positively associated with the revenue while Netflix and broadband diffusion have negative associations. For media advertising revenue, OTT advertising revenue is positively associated with the revenue while broadband diffusion has negative association. For broadcast advertising revenue, OTT advertising revenue is positively associated with the revenue while broadband diffusion has negative association.

It is difficult to make plans about the production schedule and volume of seasonal products due to the huge uncertainty in the prediction of their demands, which is why the amounts of carryover seasonal products increase after the peak season. Traditional models fail to meet the important requirements of production and stock plans related to the enhanced efficiency of logistics system due to the reduced value of carryover products by the disposal based on large discounts and deterioration, which poses considerable difficulties with actual problem solving. This study examined the stages of product storage from the specialized factory warehouses during a low season through the stores and the warehouses of local distribution centers during a high season to stock disposal and carryover product warehouses after a high season. The study developed a model for logistics rationalization plans to minimize carryover products by advance selling new products by subscription during a low season in anticipation of high season demands, increasing the accuracy of demands prediction, and making stable production plans, as well as demonstrated its excellence through numerical analysis.

This study deals with a model for platform competition in a two-sided market. We suppose there are both direct and indirect network externalities between suppliers and users of each platform. Moreover, we suppose that both users and suppliers are distributed in their relative affinity for each platform type. That is, each user [supplier] has his/her own preferential position toward each platform, and users [suppliers] are horizontally differentiated over [0, 1]. And for analytical tractability, some parameters like direct and indirect network externalities are the same across the markets. Given the parameters and the pricing profile, users and suppliers conduct subscription game, where participants select the platform that gives them the highest payoffs. This game proceeds according to a replicator dynamics of the evolutionary game, which is simplified by properly defining gains from participant's strategy in the subscription game. We find that depending on the strength of these network effects, there might either be multiple stable equilibria, at which users and suppliers distribute across both platforms, or one unstable interior equilibrium corresponding to the market tipping in favor of either platform. In both cases, we also consider the pricing power of competing platform providers under the framework of the Stackelberg game. In particular, our study examines the possible effects of the type of competition between platform providers, which may constrain the equilibrium selection in the subscription game.
