Design and Economic Evaluation on a POP Inventory Control System in SCM Using RFID
Cho, Jae Hyung ;
The Journal of Society for e-Business Studies, volume 19, issue 1, 2014, Pages 1~14
DOI : 10.7838/jsebs.2014.19.1.001
This paper presents the development of a stock control system of POP system design based on RFID in SCM and its economic efficiency. A stock control system is proposed for 900MHz passive type RFID system. The RFID system is composed of a RFID reader and four antennas to read the tag IDs. A cost estimation model is adapted based on the total product profit by various tag prices. The result of the economic efficiency analysis can indicate any invested model for the automation system which have initial investment should be used. This solution indicates the limit of the break even point according to the input. And it can be concluded that the stock control can be developed by RFID readers and passive tags with directional arrangement of several antennas. Also, the economical evaluation model can be a decision method for company to adapt the new developed system.

Cloud storage service has the potential to be a core infrastructure for the future mobile and Internet service; thus related service providers have been investing in it and trying to attract as many users as possible. In addition, those need to find out what motivates the users to keep using their service not only to attract new customers but also to secure their subscribers. Therefore, this study will examine its relationship with user`s motivation based on the extended TAM model with external variables for objective research about continuous use of cloud storage service. As a result, it was found that personal innovativeness, self efficacy, functional attributes, and psychological switching cost influence the continuous use of cloud storage service. Also, it is expected they can guide service providers to the right track when setting up their business strategy in the future.
Comparative Analysis of Game-Theoretic Demand Allocation for Enhancing Profitability of Whole Supply Chain
Shin, Kwang Sup ;
The Journal of Society for e-Business Studies, volume 19, issue 1, 2014, Pages 43~61
DOI : 10.7838/jsebs.2014.19.1.043
This research is an application of game theory to developing the supplier selection and demand allocation mechanism, which are the essential and major research areas of supply chain planning and operation. In this research, the most popular and widely accepted mechanism, the progressive reverse auction is analyzed and compared with the other game theoretic approach, Kalai-Smorodinsky Bargaining Solution in the viewpoint of holistic efficiency of supply chain operation. To logically and exquisitely compare the efficiencies, a heuristic algorithm based on Genetic Algorithm is devised to find the other optimal demand allocation plan. A well known metric, profit-cost ratio, as well as profit functions for both suppliers and buyer has been designed for evaluating the overall profitability of supply chain. The experimental results with synthesis data and supply chain model which were made to mimic practical supply chain are illustrated and analyzed to show how the proposed approach can enhance the profitability of supply chain planning. Based on the result, it can be said that the proposed mechanism using bargainging solution mayguarantee the better profitability for the whole supply chin including both suppliers and buyer, even though quite small portion of buyer`s profitability should be sacrified.

DOI : 10.7838/jsebs.2014.19.1.079
IT industry that main domain is future growth engines and convergence industry is based on national development through convergence others industry. However, shortage of advanced IT workforce is not limited to the region and urban. But, Previous studies is comprehensive research on human resource development. Human resource development studies, performance analysis and policy studies, are lacking to achieve the characterization in the region. Accordingly, The need for institutional improvement are appearing for activated regional industry through advanced Human resource development and IT convergence. in this study, we propose in order to improve institutions through IT sector performance evaluation.
Analyzing the Effects of Knowledge Resource Complementarity Structures on the Choice between Strategic Alliances and Merge and Acquisitions (M&As) in Information Technology Industries
Choi, Byounggu ;
The Journal of Society for e-Business Studies, volume 19, issue 1, 2014, Pages 95~118
DOI : 10.7838/jsebs.2014.19.1.095
The information technologies industry is now experiencing a rebirth of strong stable growth. However, very few studies have examined performance implications of strategic alliance or merger and acquisition from a knowledge-based view. Furthermore, none of these studies have investigated resource complementarities and alliance or merger and acquisition motive as potential sources of firm performance. This paper extends upon current knowledge-based literature to discover and explore linkages between resource complementarities and firm performance of strategic alliances or merger acquisitions. This study finds that strategic alliance and merger and acquisition announcements have provided abnormal positive returns of production alliances and merger and acquisition. This study can be used as a stepping stone for selection of strategic alliance or merger and acquisition.
An Empirical Analysis on Long Tail Patterns with Online Daily Deals
Jeon, Seongmin ;
The Journal of Society for e-Business Studies, volume 19, issue 1, 2014, Pages 119~129
DOI : 10.7838/jsebs.2014.19.1.119
The renowned Pareto rule of 80/20 has been challenged in the electronic marketplace with the emergence of long tail economy. Mass customization on top of the Internet infrastructure is expected to explain these changes of product concentration. In this paper, we empirically analyzed the micro-transactional data of a Groupon-like daily deal web site to identify the changes of product and customer concentration. The results show the long tail pattern aligned with the previous research on the e-commerce literature on the long tail. We find that the notification setting on email or SMS about daily deal influences the patterns of sales concentration. The information through email and SMS is expected to enable consumers to know about daily bargains and purchase the coupons eventually. However, the email notification for niche products results in the decreased sales while the SMS notification for overall product promotes overall products.
Empirical Analysis on the Shortcut Benefit Function and its Factors for Triple Database
Kang, Seungseok ; Shim, Junho ;
The Journal of Society for e-Business Studies, volume 19, issue 1, 2014, Pages 131~143
DOI : 10.7838/jsebs.2014.19.1.131
A triple database consisting of a number of three-column tables require high cost of query processing, whereby building a shortcut is known as an effective way to reduce the cost. It is important to figure out what shortcuts needs to be selectively built. Most shortcut selection algorithms make use of a benefit model that considers the query frequency. However they work poor to reflect the database update. In this paper, we consider a benefit model for triple databases. The model considers not only the profit of query response times but also the building and maintenance costs of the shortcuts. We apply the model to design a benefit function which can be plugged in a greedy-based shortcut selection algorithm. We perform the empirical experiments on a real-world dataset and analyze the effect of each factor employed in the benefit function.

The advent of ubiquitous connectivity from smart devices and network is changing the lifestyles of workers and work patterns. However, the smart work for the knowledge workers and mobile workers is not yet popular due to not enough services in supporting smart work and difficulties in employing smart work. For these reasons, it is necessary to study the current smart work industry to provide the bases for incubating smart work industry and increasing the smart work adoption. In this study, first, we reviewed and analyzed the smart work services. And then, we classified the smart work industry based on their services. Second, we conducted a survey study to identify the factors that affect on the adoption of smart work. Finally, we provided the current adoption rate of smart work services and discussed the Willing-To-Use, cost, and barriers from the smart work adoption.

Trust has been identified as crucial to intention to continue to use e-commerce systems. Although trust is inherent in relationship-based practices, most studies on trust have focused on influences on customer trust. From the viewpoint of mutual trust, few empirical studies have examined the effect of users` perceived trust from an e-commerce website on customer trust in that website, despite the obvious importance of this issue, particularly in the field of e-commerce. This paper empirically examines the role of customer perception of trust in the customer on the part of e-commerce websites. In addition, this study explores the ability of e-commerce websites` trusting actions to transfer positive impressions that encourage trust in those sites. The results indicate that in the e-commerce context, a website`s trusting actions are important to customer perception of being trusted by and trusting in e-commerce websites.
