I focused on LVTS compare with Fedwire to advance a research effects in this paper. The Fedwire Funds Service is generally used to make large-value, time-critical payments. The Federal Reserve Banks provide the Fedwire Funds Service, a real-time gross settlement system that enables participants to initiate funds transfer that are immediate, final, and irrevocable once processed. The Fedwire Funds Service is a credit transfer service. While, The LVTS(Large Value Transfer System) is the high value electronic wire system that facilitates the transfer of irrevocable payments in canadian dollars across the country. Through LVTS, funds can be transferred between participating financial institutions virtually instantaneously in a fully collateralized environment. Thus in this article, first of all, I considered features of payment system between LVTS and Fedwire. Second, I analyzed the governing structure and legal background. Third, I focused on the operational policy and risk aversion policy. Lastly, I suggested that the payment and banking system have to assume, with good reason, more efficiently accurately and securely operation together with conclusion.

The main purpose of this study is to examine the rewards for "Family Care" from the Japanese Long-Term care policy, to investigate the effects of "The commodification of Family Care" after the introduction of "The Long-Term Care Insurance", and to find out the institutionalization of reward system for "Family Care". First of all, the socialization of "The Long-Term Care" is redefined to be the commodification of family care in this study. Based on this definition, the commodification of family care and the government's involvement are analyzed in conjunction with considering the role of family in the process of Long-Term Care supply, the social evaluation for family care, the family carers' home environment and the position in the labor market. In result, the commodification structure of family care in the Japanese Long-Term Care policy is found, and it helps to understand the reason why the cash payments was just partially introduced.

A review on the technical development and agricultural policy direction for sustainable agriculture has been made to clarify the present conditions of agricultural environment for food production and natural resource conservation and to study prospects and solutions successfully to achieve food safety and environment conservation as the 21st agricultural paradigm. Although great improvement of environmentally sound and resource-conserving techniques, sustainability of Korean agriculture has been damaged by quantitative reduction and quality deterioration of agricultural land resources, insufficient implementation of low-input and organic matter recycling techniques and also improper cropping system. It is concluded that goal of sustainable agriculture can be successfully achieved by further improvement of environmentally friendly techniques, and stronger escalation of national implementation programmes with more financial supports including direct payments for sustainability of agriculture under systematical support and cooperation of AKS (agricultural knowledge system).

This paper presents a unique approach to scheme a demand response (DR) program in the electricity market from a customer-oriented perspective, which is based on the analytic hierarchy process (AHP). The proposed program is designed as an incentive-based program (IBP) considering Korea power systems with the cost-based generation pool (CBP). And the proposed DR program has the objective to maximize social welfare corresponding customers‘ participation and the constraints including incentive payments, the specific load curtailment conditions and reserve-margin criterion. A test system for the case study is used to demonstrate the usefulness and applicability of the proposed approach, and the load profiles with the proposed DR program are obtained. The results show not only the revenue attributable to the avoided costs but also enhancement of system reliability.

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.

A payment system is required to buy various services and micropayment system is demanded for minimizing a frequent payment transaction cost in ubiquitous environment. It is not guarantee that devices are always online and payment system is required a robustness when some of them is offline. To solve this situation other systems use a centralized broker but the problem with most existing micropayment system is the heavy load on the broker. In this paper present a payment system a DHT based Peer-to-Peer micropayment system for ubiquitous environment can use even if payments need not be online and reduce broker's load.

An anti-fraud system that utilizes association rules of fraud as well as AFS (Anti Fraud System) for credit card payments in e-commerce is proposed. The association rules are found by applying the data mining algorithm to millions of transaction records that have been generated as a result of orders on goods through the Internet. When a customer begins to process an order by using transaction components of a secure messaging protocol, the degree of risk for the transaction is assessed by using the found rules. More credit information will be requested or the transaction is rejected if it is interpreted as risky.

The system proposed in this paper is a fully automated parking control system that can even protect users' information through blockchain. Unlike conventional parking control systems, the system consists of a web page that is accessible to people of all ages and ages, directly to the parking lot. Such a system would also benefit managers in the parking lot business. This is because it can reduce soaring labor costs and maximize the sales it can generate by operating 24 hours a day. In order to implement these systems, the web page was first designed using HTML and the API was configured using JAX-RS to invoke the API required by the web page. As a result, it created a web page that was easily accessible to anyone, built a server that could be accessed by more than 200 people at the same time, focused on personal information protection by encrypting the information of users through blockchain grafts, and designed a system that enabled users to complete payments easily. It is planning to add QR codes and GPS functions in the future and implement a function that allows one-touch information on parking lots and their vehicle information.
