Due to the progress of the 4th industrial revolution and the COVID-19 pandemic, the subscription economy was rapidly expanding. In particular, the subscription economy was expected to expand further as the servicing of products(servitization) rapidly progresses. In this study, we tried to empirically analyze the factors that promote and hinder the spread of the subscription economy from the consumer's point of view. To this end, based on the Service Profit Chain (SPC) model, which identified mechanisms leading from quality to satisfaction, loyalty, and performance, a research model was established by combining the framework of the Value-based Adoption Model (VAM), which covers both benefit and sacrifice factors. Usefulness and convenience were derived as benefit factors, and perceived risks and perceived costs were derived as sacrifice factors. The effects of these factors on satisfaction and continuous use intention were analyzed. For empirical analysis, a survey was conducted targeting people who have experience in subscription economy, and 300 effective samples were analyzed. The analysis was performed as a structural equation model using AMOS 24. As a result of the empirical study, it was found that convenience had a significant positive (+) effect on satisfaction. Perceived risk and perceived cost were analyzed to have a negative (-) effect on satisfaction. On the other hand, usefulness was found to have no significant effect on satisfaction. The influences affecting satisfaction were in the order of perceived cost, convenience, and perceived risk. Satisfaction was found to have a significant positive (+) effect on continuous use intention. The results of this study were considered meaningful in that they broadened the horizons of research by combining existing validated models at the academic level and testing their validity, and found that perceived cost was still an important factor at the practical level.

Owing to the advent of digital devices which equipped with GPS, such as smartphone and tablet pc, a number of LBSNS applications have been released and even SNS applications serve various Location-Based Services. In twitter's case, the news of interesting area is provided to user not by being subscribed them automatically, but by being searched on web-site. This paper describes the system designed for users want to subscribe the local news without procedure like searching using operators. This system uses PBSM(Partition Based Spatial-Merge Join) which has no index for batch processing and against a massive query. The results from Spatial Join are stored in Materialized View then provided to user.

OMG(Object Management Group)의 데이터 분배 서비스(DDS: Data Distribution Service)는 발간(publish)/구독(subscribe) 모델에 기반하여 동일한 타입의 데이터를 실시간으로 주고 받는 데이터 중심의 분산 환경에서 많이 사용되는 통신 미들웨어 기술이다. 하지만 DDS는 실시간으로 발생하는 데이터에 대하여 일회성인 특징을 갖기 때문에 추후 데이터에 대한 분석, 검증 등을 위해 영속성을 제공할 필요성이 증대되고 있다. 이러한 추세를 반영하듯 RTI DDS, PrismTech Opensplice 등의 대표적인 DDS 시스템에서는 데이터베이스를 연동하기 위한 연구를 진행하고 있다. 실시간 통신 미들웨어인 DDS와 데이터베이스의 연동은 DBMS 애플리케이션이 일반적으로 데이터베이스를 사용하는 것뿐만 아니라 DDS의 시맨틱을 알지 못하더라도 데이터 중심의 발간/구독 모델을 유기적으로 활용할 수 있는 장점을 지닌다. 본 논문에서는 이를 위해 DDS 시스템인 DB-ReTiCom의 데이터베이스를 사용하기 위한 커넥티비티를 제안하고 사용자 친화적 인터페이스를 위한 변환 방법을 제시한다.

It has become the heavy burden for many domestic colleges to renew the e-journal paywall licenses because major publishers keep raising license fees to access the new articles in Korea. In order to overcome these costly expenditure, the universities in US and the several governments in EU attempted the new models of open access option in the form of pilot contract with major publishers. Unlikely, there is no active discussion regarding open access options among domestic scientists, which may limit the generation of creative models in Korea. In this paper, the cases of US and EU negotiations with the Elsevier publisher were introduced and also evaluated in a qualitative manner whether any combined models could be applicable to future consideration.

Although academic library budgets have been decreasing, the rates of print and electronic journal subscription price have consistently increased. In response to this, as part of efforts to ensure access to foreign academic materials, the Ministry of Education and Korea Education & Research Information Service (KERIS) have initiated and operated Foreign Research Information Center (FRIC) since 2006, pursuing shared acquisition and sharing of foreign print journals. This study investigates the roles/values, issues raised by stakeholders, improvements in services, and new service elements of FRIC through the in-depth interviews with librarians in charge of FRIC in addition to examining its current state. The findings show that FRIC has contributed to sharing of academic materials and to promoting research. However, it was also found that the five types of stakeholders (i.e., the Ministry of Education/KERIS, universities/libraries, users, FRICs, and publishers/agencies) have diverse issues and problems with FRIC. Therefore, this study makes some suggestions to address the issues in terms of policy, system, management, and service.

The LBSNS(Location-Based Social Networking Service) service has been well-received by researchers and end-users, such as Twitter. Location-Based service of Twitter is now structured that users could not subscribe the information of their interesting local area. Those who being following from someone tweet message included information of local area to them just for their own interesting. However, follower may receive that kind of tweet. In order to handle the problem, we propose filtering technique using spatial join. The first work for filtering technique is to add a location information to tweets and users. In this paper, location information is represented by MBR(Minimum Bounding Rectangle). Location information is divided into dynamic property and static property. Suppose that users are continuously moving, that means one of the dynamic property's example. At this time, a massive continous query could cause the problem in server. In this paper, we create Virtual Grid on Google Map for reducing frequency of query, and conclude that it is useful for server.

In nowadays, Covid-19 has transformed patterns of consumers' behavior into a non-face-to-face mode. As the patterns of consumption have been digitalized, it has become a daily routine for consumers who perform so-called shadow work, which involves unpaid jobs that they have to do by themselves. In mobile grocery service context, consumers' shadow work could lead to shopping avoidance as well as switching toward other shopping channels. Thus, this study is to examine how consumers' perception of shadow work affect mobile shopping avoidance and switching intention toward other shopping channels. This study collected 283 survey data from online respondents who have experience on subscription services for ordering groceries in online. We also tested our research model by using partial least squares. Based on our results, this study has found that the perception of shadow work had a positive effect on mobile shopping avoidance as well as switching intention. We expect that our findings could contribute to relevant research on shadow work and suggest practical implications for digital platforms dealing with subscription business models

Price promotion is one of the most frequently marketing strategies with a long history. According to various studies, the effect of price promotion is controversial. Some studies have argued that price promotion has a positive effect, while others have found that it has no effect or rather has a negative effect. This study aims to examine the effect of price promotion in a subscription-based service. First, we check the effect of price promotion on the repurchase of the consumer. And we investigate how this effect varies depending on the characteristics of the consumer. Using the data from one of the music streaming service in South Korea, the effect of consumers' price promotion experience, demographic characteristics, and behavioral characteristics on their repurchase is analyzed through logistic regression analysis. As a result of the study, it is found that consumers' experience of price promotion has a positive effect on repurchase. In addition, the positive effect of price promotion is relatively greater in younger and female consumers. This study has implications in that it not only confirmed the positive effect of price promotion in a subscription-based environment but also empirically confirmed that the characteristics of consumers should be considered when performing price promotion.
