  • In this study, we investigated the problems of existing e-journal subscriptions caused by open access of e-journals faced by university libraries. To solve these problems, we proposed an operational model for open access based subscription. The proposed operational model, which adapts the four concepts of subscription model, system, policy, and operation interpreted according to reality, applies open access on the premise of rational subscription of electronic journals. The proposed operational model was constructed based on national support, comprehensive operation, open access based model, and cooperation system. In particular, it emphasized the need for stable and continuous access to scholarly information through national support policy. The proposed operational model can be used as a basic data for the realization and research of open access in the domestic environment.

  • 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.

  • As interest in adolescent and children's health risks increases, there is an increase in subscriptions to indemnity private health insurance. The purpose of this study was to investigate determinants of purchasing indemnity private health insurance. We conducted panel logit regression analysis on the sample of 4,567 adolescent and children using Korean Health Panel data from 2009 to 2015. As a result, it was analyzed that the participation of private health insurance for children and adolescents was affected not only by the characteristics of children and adolescents (age, birth order, residence, disability) but also by the characteristics of father (indemnity, disability, chronic disease) and mother (age difference between her and her children, indemnity, unmet needs) and the economic level of households (income). In views of this study, it is necessary to continuously implement policies to strengthen the healthcare of children and adolescents in order to alleviate the anxiety about the health risks of children and the burden of medical expenses caused by late marriages and maternal births. In particular, it is necessary to consider policies for multi-child families and vulnerable classes.

  • The most remarkable business model to Have merged in electronic publishing is the so-called 'Big Deal'. Major Publishers have begun offering libraries bundled packages that are across journals and across print and electronic versions. This paper examined consortium conditions of scholarly journals in the light of big deal. The result skewed that various pricing models have been appeared and freedoms to choose collections have been on the increase in comparison with the past. But many major Publishers have adopted a typical big deal contract condition that a library enters into a long-term arrangement to get access to large electronic journal collections at a dramatic discount interchange of a promise not to cut print subscriptions. The publishing and library communities need to find alternative pricing models that provide better deals for those disadvantaged by the prevalence of the big deal. Much in the world of scholarly publication is changing, combination of traditional publishing and open access publishing may well be gained public favor in the future.

  • The presence service which provides user's presence information by subscription and notification is one of SIP(session initiation protocol) extension services, and it is used importantly in VoIP(Voice over IP) and Instant Messaging service. In this paper, we propose a new method in which users can combine and control presence service and call processing services in various ways by extending call processing language, and only changed parts of the presence information are published instead of full presence information document. Each user registers full presence information document with his own call processing script during the first publication to a presence server. The presence server executes these call processing scripts, so it can provide various services with combination of presence service and call processing services during the presence subscriptions and notifications. Afterwards, users publish only changed parts of the presence information and the presence server notify only these changed parts to watchers. Therefore the efficiency of the overall system can be improved. The performance of our proposed model is evaluated by experiments.

  • The quality of education is determined by the quality of teachers, and in particular the competence of principals is important for the desirable flow of schooling. The Principal employment system was adopted as one of the educational reforms introduced by the government. However, even though it has been 10 years since the enactment of PES, the perception of that has been low. To solve this, first, government should be more active in promoting publicity for the principal. Second, the elected principal should not be concentrated only in small areas, but should spread to urban areas. Finally, principals must increase the rate at which practitioners are able to contribute substantially to public subscriptions.

  • The interaction between wireless sensors such as Internet of Things (IoT) and Cloud is a new paradigm of communication virtualization to overcome resource and efficiency restriction. Cloud computing provides unlimited platform, resources, services and also covers almost every area of computing. On the other hand, Wireless Sensor Networks (WSN) has gained attention for their potential supports and attractive solutions such as IoT, environment monitoring, healthcare, military, critical infrastructure monitoring, home and industrial automation, transportation, business, etc. Besides, our virtual groups and social networks are in main role of information sharing. However, this sensor network lacks resource, storage capacity and computational power along with extensibility, fault-tolerance, reliability and openness. These data are not available to community groups or cloud environment for general purpose research or utilization yet. If we reduce the gap between real and virtual world by adding this WSN driven data to cloud environment and virtual communities, then it can gain a remarkable attention from all over, along with giving us the benefit in various sectors. We have proposed a Pub/Sub-based sensor virtualization framework Cloud environment. This integration provides resource, service, and storage with sensor driven data to the community. We have virtualized physical sensors as virtual sensors on cloud computing, while this middleware and virtual sensors are provisioned automatically to end users whenever they required. Our architecture provides service to end users without being concerned about its implementation details. Furthermore, we have proposed an efficient content-based event matching algorithm to analyze subscriptions and to publish proper contents in a cost-effective manner. We have evaluated our algorithm which shows better performance while comparing to that of previously proposed algorithms.

  • The speed and magnitude of mobile phone adoption is a recent worldwide phenomenon akin to those of the television in the middle of the 20th century and the Internet in the late 20th century. During the 2000s, mobile phone adoption was exploded and subscriptions reached 3 billion around the globe. Korea and Japan have been ahead of the rest of the world in introducing new handset and service capabilities. They were the first markets to launch 3G services and are currently the only markets to have achieved mainstream adoption of 3G with over one-third of customers in both markets subscribing to 3G services. The purpose of this article is to explore the cultural similarities and differences associated with mobile mail by presenting findings from a cross-cultural comparison of perceptions and uses of the technology. The results of the study are as follows:Of the characteristics that make up the mobile text-messaging service in Korea, a person's perceived ease of use and perceived enjoyment was found to have a positive effect on use attitude. Among the characteristics that make up a person's perceived ease of use, perceived enjoyment was found to have a positive effect on use intention. And use attitude was found to have positive effects on use intention. But, of the characteristics that make up the mobile text-messaging service in Japan, a person's perceived usefulness, perceived ease of use and perceived enjoyment were found to have a positive effect on use attitude. Among the characteristics that make up a person's perceived usefulness, perceived ease of use and perceived enjoyment were found to have a positive effect on use intention. And use attitude was found to have positive effects on use intention. This study contributes to telecommunications research by delineating the various stimuli to consider for successful technology acceptance in a global setting, which can account for differential impacts across regions. The findings of this study can assist telecommunications operators in formulating an effective region-specific strategy when launching a wireless data service in a particular environment.

  • As everything linking to the internet, people can subscribe to various services from a service provider to facilitate their lives through the Internet of Things (IoT). An obligatory thing for the service provider is that they should push the service data safely and timely to multiple IoT terminal devices regularly after the IoT devices accomplishing the service subscription. In order to control the service message received by the legal devices as while as keep the confidentiality of the data, the public key encryption algorithm is utilized. While the existing public encryption algorithms for push service are too complicated for IoT devices, and almost of the current subscription schemes based on push mode are relying on centralized organization which may suffer from centralized entity corruption or single point of failure. To address these issues, we design a secure subscription-push service scheme based on blockchain and edge computing in this article, which is decentralized with secure architecture for the subscription and push of service. Furthermore, inspired by broadcast encryption and multicast encryption, a new encryption algorithm is designed to manage the permissions of IoT devices together with smart contract, and to protect the confidentiality of push messages, which is suitable for IoT devices. The edge computing nodes, in the new system architecture, maintain the blockchain to ensure the impartiality and traceability of service subscriptions and push messages, meanwhile undertake some calculations for IoT devices with limited computing power. The legalities of subscription services are guaranteed by verifying subscription tags on the smart contract. Lastly, the analysis indicates that the scheme is reliable, and the proposed encryption algorithm is safe and efficient.

  • The Internet is extremely important to accomplish numerous items, from education to businesses and entertainment. Therefore, the quality of its performance must be efficient. Nowadays, there is a lack of information available for users to choose a suitable Internet service. What information is available might be insufficient, inaccurate, or regularly updated. Accordingly, there is a need to develop an electronic system that enables users to evaluate their current Internet service subscription. Several factors are used as evaluation criteria in the system that affect users' decisions. In this paper, a prototype of a design science research project is proposed to address a few objectives. First, it can help Internet service users in Saudi Arabia to make the best decision for themselves regarding Internet services subscriptions. Second, it can assist the Saudi government to seek one of the 2030 vision goals: the digital transformation that depends on having a good Internet connection. The proposed solution is a promising one that would help Internet service users to make the best decision for themselves and choose the best Internet service that fits their needs. A qualitative method has been used to evaluate the efficiency and the utility of the proposed system prototype. The results showed the extent of participants' acceptance of the Internet Service Evaluation System.
