Technological developments facilitate payment transactions. In 2020, Bank Indonesia issued a regulation that supports QR payments using the Indonesian Standard Quick Response Code (QRIS). PT ABC is one of the banks that launched a QR payment feature on mobile banking with QRIS standards to make it easier for customers to make payment transactions at various merchants. In its implementation, the interest of QR payment users still tends to be small, so an analysis of the interests of QR payment users is carried out. The purpose of this study is to analyze the factors that influence user interest by using a modified UTAUT model. The UTAUT model was modified by adding variables to perceived trust, perceived risk, perceived regulatory support, and promotional benefits. The population taken is the company's customers in the DKI Jakarta area and it takes 403 samples for this case study. The results of empirical analysis show that 8 out of 12 hypotheses are considered proven where business expectations, social influence, perceived trust, perceived risk, perceptions of regulatory support, promotion benefits, age-moderated performance expectations, and age-moderate effort expectations have a significant effect on behavioral intentions, while performance expectations, facilitation conditions, business expectations are moderated by experience and social influence.

Globally, Fintech, which acts to replace existing intranational payment methods, is actively used, and such Fintech payments are widely accepted in international B2C trade. However, Fintech for B2B trade has not been released to the market thus far, and previous attempts at electronic international payment systems, such as Bolero, TradeCard, and Identrus, have not succeeded, and most of them have completely disappeared. On the other hand, there are continuing attempts to introduce Fintech technologies such as blockchain to international payments, and these attempts are more widely pursued in foreign countries. If international payments using Fintech are marketed through foreign services and such Fintech services become the de-facto standard for international payments, then Korea in which dependency on international trade is high will be vulnerable due to a dependency on foreign services such as relying on foreign SNS platforms like Facebook and Instagram. Therefore, this paper proposes a business model that can be used as a legitimate B2B trade international payment system on the basis of domestically provided services, focusing on various services afforded by K-SURE, which is the Korea Trade Insurance Corporation.

Although the Korean construction industry has risen rapidly, the quality of the buildings is not met with the industry standard compared to the potential of the technology development and the cost of maintenance has been increased. The user's request for quality have been increased, but in the current building construction, the contractors only follow the specifications of design, material and technology, and their main concern is whether they are in right track with the specification or not. Thus, the necessity of developing technology has been ignored and sufficient opportunities for the development have not been provided as well. In the developed countries, in contrast, the quality assurance and the payment regulation system has been utilized for the active response to the changes of users' request. As a result of this, the maintenance cost has been decreased and the development of construction technology has been improved. Therefore the pay adjustment system is needed to create the improvement of the quality of the buildings by the contractors' earnest building construction. In order to introduce the pay adjustment system suitable to the Korean construction industry, this study presented the logical method of adjusting the construction cost and making payment with the pay adjustment index that is created based on the result of the performance test, after making a set of the indicators of the building performance standard and applied them to the targeted building.

Purposes : In February 2014, the government said that the National Health Insurance Service (NHIS) will enforce plan for reducing the financial burden from two major non-covered services including physician surcharges and private room charges, the main causes to increase uninsured, by 2017. The purpose of this study is to analyze the policy effect that performed so far by comparing out-of-pocket payment rates of policy process Methodology: This study analyzed admission medical expenses that occurred from January 2013 to March 2016 at a upper grade general hospitals in Daejeon. Number of study subjects were 134,924 and the data were analyzed with SPSS 22.0 program by using frequency, percentage, mean, standard deviation, ANOVA. The effect of two major non-payment improvement plan on out-of-pocket rates was ascertained via generalized estimating equation. Findings: Out-of-pocket payment rates was statistically significantly declined 2.7 percent than enforcement ago. Also, out-of-pocket payment, physician surcharge, the proportion of out-of-pocket payment of hospital room charge to out-of-pocket payment was statistically significantly declined. However, a further analysis of the cause of the decline in total medical costs is needed. Practical Implications: Physician surcharges and private room charges improvement policy had a positive effect on the decline of out-of-pocket payment rate. The policy of physician surcharges was very effective after the first policy enforcement but it was less effective to medical aids and near poor that was a more greater coverage than national health insurance. Since the policy has not been finalized, we have to continue a research for the successful implementation of the policy.

EMV was formed in February 1999 by Europay International, MasterCard International and Visa International to manage, maintain and enhance the EMV Integrated Circuit Card Specifications for Payment Systems as technology advances and the implementation of chip card programs become more prevalent. The formation of EMV ensures that single terminal and card approval processes are developed at a level that will allow cross payment system interoperability through compliance with the EMV specifications. A credit card environment of the domestic market adopted the standard Local-EMV to have the compatibility with EMV international standard and the EMV migration have been carried out b,# the step-by-step process. It may be possible to adopt various kinds of cryptographic algorithms, however, RSA public key algorithm is currently used. In this paper, as a public key algorithm for the authentication process, Elliptic Curve Cryptographic algorithm is applied to the EMV process. Implementation results is shown. and the possible changes necessary to accommodate Elliptic Curve Cryrtography is proposed.

One of the fastest-growing mobile services accessible today is mobile payments. For the safety of this service, the Near Field Communication (NFC) technology is used. However, NFC standard protocol has prioritized transmission rate over authentication feature due to the proximity of communicated devices. Unfortunately, an adversary can exploit this vulnerability with an antenna that can eavesdrop or alter the exchanged messages between NFC-enabled devices. Many researchers have proposed authentication methods for NFC connections to mitigate this challenge. However, the security and privacy of payment transactions remain insufficient. We offer a privacy-preserving, anonymity-based, safe, and efficient authentication protocol to protect users from tracking and replay attacks to guarantee secure transactions. To improve transaction security and, more importantly, to make our protocol lightweight while ensuring privacy, the proposed protocol employs a secure offline session key generation mechanism. Formal security verification is performed to assess the proposed protocol's security strength. When comparing the performance of current protocols, the suggested protocol outperforms the others.

This study investigates the effect of related variables (types of job, term of employment, working time, job satisfaction, payment satisfaction and, working stress) on the sense of hopelessness felt by married males. The study was conducted on 237 male employees residing in Busan, and measurement devices for study were job-related variables, working stress and hopelessness scale. The study used SPSS 12.0 program to analyze data, and conducted item analysis and reliability test for measure establishment. Average, Standard deviation, one-way ANOVA, scheffe-test, Pearson correlation, and path analysis through regression analysis were conducted pertaining to research subject. The result of this study is as follows; First, working stress has significant difference upon types or working, term of employment and job satisfaction. Office workers relatively have longer term of employment and workers who are less satisfied with job suffer from more working stress. Second, hopelessness has significant difference upon term of employment, job satisfaction and payment satisfaction among job-related variables. Thus, hopelessness is relatively less when term of employment is shorter and job satisfaction and payment satisfaction is higher. Third, variables which affect directly to working stress and hopelessness are term of employment $(\beta=.245)$, payment satisfaction $(\beta=-.182)$ and working stress $(\beta=.189)$, and types of job, term of employment and job satisfaction influences hopelessness indirectly through working stress. In conclusion, workers are more negative when term of employment is longer, payment satisfaction is less and working stress is higher. Moreover, longer term of employment and less job satisfaction contribute to higher working stress and eventually influence hopelessness. Term of employment affects the most to hopelessness $(\beta=.274)$, and it is followed by working stress $(\beta=.189)$ and payment satisfaction $(\beta=-.182)$.
