선불방식의 화폐시스템에서 고객은 인출한 화폐를 은행으로부터 환불받을 수 있어야 한다. 그러나 분할된 화폐가 서로 연관될 수 있는 분할 가능한 화폐시스템에서는 고객이 사용한 화폐의 익명성을 유지하면서 남은 금액을 환불해주기가 어렵다. 이 논문에서 이런 문제를 해결한 새로운 방식의 환불 메커니즘을 제공한다. 제안된 새 방식에서 고객은 은행에 익명으로 접근하여 환불티켓을 인출하고, 나중에 인출된 티켓을 이용하여 기존 지불의 익명성을 유지하면서 환불을 받게 된다. 환불티켓을 사용하면 환불과정을 인출이나 지불과정과 독립적으로 제공할 수 있어 환불이 필요없는 경우에는 아무런 추가비용이 소요되지 않는 장점이 있다. 또한 같은 이유에서 여러 시스템에 쉽게 응용이 가능한 유연한 방식이다. 끝으로 환불액을 계속해서 하나의 티켓에 축적하는 방법을 사용하면 지불액과 환불액간에 직접적인 차액관계가 없어지므로 고객의 익명성이 증진되며, 은행에 접촉해야 하는 횟수를 줄여주는 효과가 있다.

As an effort of mitigating hazards, pro-environmental programs have been vigorously activated with regard to solid waste recycling. It is beneficial for both the environment and resource saving, but implementation and enforcement are hard to achieve voluntarily. The South Korean Government first implemented the Deposit Refund System (DRS) and later the Extended Producer Responsibility Program (EPR) to reduce waste and encourage recycling in South Korea. Un-der the DRS, producers would pay for recycling the wastes of the products. The government then repealed the DRS and implemented the EPR program. Under this program, the producers recycle as much as the Ministry of Environment determines or pay a penalty for an excessive amount of the waste. In the broader perspective of disaster management, such policy programs can mitigate environmental hazards. This paper compares those two programs that facilitated the level of recycling, focusing on how such programs regulate producers and how they were operated from the perspective of implementation and enforcement.

We investigate the dynamic asset allocation problem under inflation risk when the wealth of an investor is constrained with minimum requirements. To capture the investor's risk preference, the CRRA utility function is considered and he maximizes his expected utility at predetermined date of the refund by participation in the financial market. The financial market is supposed to consist of three kinds of financial instruments which are a risk free asset, a risky asset, and an index bond. The role of an index bond is managing inflation risk represented by price process. The optimal wealth and the optimal asset allocation are derived explicitly by using the method to get the European call option pricing formula. From the numerical results, it is confirmed that the investments on index bond is high when the investor's wealth level is low. However, as his wealth increases, the investments on index bond decreases and he invests on risky asset more. Furthermore, the minimum wealth constraint induces lower investment on risky asset but the effect of the constraints is reduced as the wealth level increases.
