This paper analyzes the main factors affecting user selection of a small-sum electronic payment system using survey data of 396 users. Several findings emerge. First, users consider three pillars and eight factors in adopting a new system : system features(stability, security, and flexibility), transaction cost(payment commission and settlement period), and financial capability of provider(stability of financial structure, risk management capability, and funding capability). Second, the stability of the financial structure of the system provider is the most important factor to user acceptance of a new e-payment system. Users tend to consider uncertainty risk more seriously than transaction cost. This reflects the reality that electronic payment system service industry has not fully fledged yet. Third, some moderating effects exist according to payment methods and business usages. As for payment methods, speedy settlement cycle for wired/wireless phone payment, system stability for credit card and account transfer payment, and security for advance payment means are crucial factors. As for business usages, the stability of financial structure for online game content, system stability for music and video content, proxy payment commission for e-learning content, flexibility of the payment system for digital adult content, and security for public services are decisive ones.

This study was conducted to analyze the effect of information security activities on organizational performance. With this in mind and with the aim of resolving transaction stability in the securities industry, using an organization's security activities as a tool for carrying out information security activities, the effect of security activities on organizational performance was analyzed. Under the assumption that the effectiveness of information security activities can be bolstered to enhance organizational performance, such effects were analyzed based on Herzberg's motivation theory, which is one of the motivation theories that may influence information protection activities. To measure the actual attributes of the theoretical model, an empirical survey of the securities industry was conducted. In this explorative study, the proposed model was verified using partial least squares as a structural equation model consisting of IT service, information security, information sharing, transaction stability, and organizational performance.

Smart Card is currently more popular in mobile communication, and smart card with java card platform becomes a standard choice. Java card has a problem that it gets lost working data when power is off. Transaction is the idea to solve a problem of data loss, but it accepts only one transaction process, and other transaction process need to hold until the current working transaction is finished. This might be a factor to drop the Java card's performance. In this paper, we define a rule of dual-lock which can run transaction at multiple transaction buffer as a method for a better java card performance, and we suggest this rule to improve a capability of transaction process. From this research, we are able to improve the data stability, reduce the java card transaction delay time, and get a higher processing speed of java card.

In this paper, the performance of various blockchain consensus algorithms was compared and analyzed as a method to increase the transaction cost and processing time during NFT transactions and to increase the transaction stability requirements that occur during smart contract execution. Network reliability and TPS are evaluation items for performance comparison. TPS and the stability of the Consensus algorithm are presented for three evaluation items. In order to establish a standardized expression for each evaluation item, the reliability of the node and the success rate of the smart contract were considered as variables in the calculation formula, and the performance of the consensus algorithm of the three groups, PoW/PoS, Paxos/Raft and PBFT, was compared under the same conditions. / analyzed. As a result of the performance evaluation, the network reliability of the three groups was similar, and in the case of the remaining two evaluation items, it was analyzed that the PBFT consensus algorithm was superior to other consensus algorithms. Through the performance evaluation equations and results of this study, it was analyzed that when the PBFT consensus processing process is reflected in the consensus process, the network reliability can be guaranteed and the stability and economic efficiency of the consensus algorithm can be increased.

This paper focuses on the asymptotic stability of a class of neutral linear systems with mixed time-varying delay arguments. Using the Lyapunov method, a delay-dependent stability criterion to guarantee the asymptotic stability for the systems is derived in terms of linear matrix inequalities (LMIs). The LMIs can be easily solved by various convex optimization algorithms. Two numerical examples are given to illustrate the proposed methods.

Recently, interest in virtual money has been growing. There is also a view that it is safe to pursue traditional assets, and some wealth experts are expecting positive changes in the financial society that can be diversified due to virtual money. Since the virtual money market is an immature situation and the stability of the virtual money is not yet secured, the potential risk of the transaction of the virtual money is highly likely to occur. In this study, we try to derive important priorities by deriving the evaluation factors that can contribute to the stabilization of the virtual currency in the market transaction. The main evaluation factors were selected from the viewpoint of the transaction environment, the technical viewpoint, and the profit viewpoint, and the importance of the subordinate factors was analyzed by applying AHP.

In this paper, we research to secure stability of data storing/searching on NoSQL implemented on Distributed File System. When implementing NoSQL on Distributed File System, we faced that random write on Distributed File System is almost impossible. To solve this problem, a concept of Intermediate-File was employed, and then it has been achieved that our system resist any failure circumstance. Additionally, since we discovered its performance cannot be as fast as general File System, by redefining the file block unit for our NoSQL system, we have prevented a slowdown in system performance. As a result, we are able to develop highly scalable NoSQL as Distributed File System, which fulfills basic conditions of transaction: Atomicity, Consistency, Isolation, and Performance.

Purpose: This study examines components that dictate service quality of Online Travel Agencies. Research design, data and methodology: This study performed a survey that targeted people who have purchased travel products using Online Travel Agencies in the past year at Incheon International Airport. Out of 280 questionnaires, this study selected 249(88.9%) questionnaires for analysis. In analysis, this study used statistical package called 'SPSS 22'. Results: Based on the results, this study identified that company reputation and transactional stability influenced consumers' intent to share anecdotal and practical information. Conclusions: This study discovered several major findings. First, 'convenience' and 'price', two major factors in service quality, imposed positive effects on word-of-mouth intention of consumers. In particular, 'convenience' had the most significant impact. Next, this study verified the moderating effects of 'transaction safety' and 'reputation' on the effect relationships between 'convenience' and 'price', and consumer word-of-mouth intention. The results conclude that, in fact, some statistically significant differences among the effect degrees of the two independent variables on the dependent variable according to the safety level of transaction on Online Travel Agencies website do exist. In short, 'transaction safety' variable does have moderating effects on the above relationships.
