This study examined the effects of consumers' perceptions and expectations about refund on consumers' behavior to refund and its outcome. Major results of this study could be summarized as follows. First, consumers' perceptions and expectations about refund were higher in the case of defective products. However, consumers' behavior to refund were generally passive resulting in the low chance of refund. When there was no defects in product, consumers perceptions and expectations for refund were generally lower resulting in passive and the low chance of refund. Second, when there was defects in product, both consumers' perceptions and expectation tot refund influenced their active behaviors for refund, but not in the successful outcome. In contrast, when there was no defect, those two variables impacted on the behaviors for refund positively In addition, the more active those behaviors requesting for refunds were, the more successful outcome in refund request.

A hash chain is highly efficient, attractive structure to use in electronic cash. Previous systems using hash chain were, however, either credit-based vendor-specific cash or debit-based general-purpose cash which lacks efficiency due to double spending problem. In this paper, we propose a new divisible cash system using hash chain. This newly proposed cash is general-purpose, debit-based, anonymous, and offline. The efficiency of the system results from its capacity to pay variable amounts with no additional costs. A client always performs a single blind signature in the withdrawal phase, independent of the length of the chain. During payment, a client performs a single challenge-and-response or generates a single signature, independent of the amount paid. This system provides a new refund mechanism, which uses a refund ticket, that allows clients to refund the unspent part of the chain without revealing any connection to the spent part.

소셜커머스의 이용의 증가와 더불어 단점이 부각되고 있다. 하지만 소셜커머스의 특성상 소셜커머스 사이트를 통해 소개되어지는 업체들은 대부분이 소비자들이 많이 접하지 못했던 영세 업체가 많고, 사용자들은 미리 구입한 쿠폰을 통해서 받은 상품의 질과 서비스가 좋지 않아도 이벤트 성으로 이루어진 판매이기에 환불이나 교환 등이 어렵다는 점에서 소비자의 주의가 필요하다. 본 논문에서는 PMI-IR 수식을 이용하여 소셜커머스에서 거래가 이루어지는 상품명과 연관 있는 상위 세개의 평을 추출하여 제공함으로써 상품의 질과 서비스에 대한 평가를 알아보고 사용자의 신뢰성 있는 거래를 도모한다.

티켓은 우리의 문화생활을 위한 필수 불가결한 요소이다. 그러나 기존의 티켓 시스템에 대한 소비자들의 불만과 악의적인 범죄 피해가 늘어가는 상황에서 새로운 대안의 필요성이 커졌다. 이를 해결하고자 Klaytn 기반의 NFT 시스템으로 티켓을 NFT화하여 수수료 및 환불에 대한 소비자들의 피해와 불만을 해소하고, 티켓 거래의 투명성을 제고하는 티켓 예매 및 거래 플랫폼 방안을 제시한다.

본 연구에서는 인터넷 쇼핑몰에서 불만족을 경험한 고객들의 불평요인 및 불평행동유형을 파악하고, 쇼핑몰 업체의 불평처리방법에 대한 평가를 바탕으로 효과적인 불평처리방안을 제시하였다. 연구 결과 불평행동을 하는 고객의 유형은 직접행동파, 사적행동파, 소극행동파, 적극행동파 등으로 구분되었다. 이 가운데 사적행동파가 가장 높게 나타나 인터넷 환경에서는 사적행동파에 대한 효과적인 불평처리 방안에 관한 노력이 가장 필요한 것으로 확인되었다. 직접행동파는 해당 쇼핑몰 업체에게 직접 문제해결을 요구하기 때문에 불평처리에 대한 공정성, 불평 후 만족과 충성도 측면에서 가장 효과적인 것으로 확인되었다. 그리고 고객의 모든 불평행동유형에서 가장 심각한 불만족 요인으로는 배송오류 및 지연과 제품결함인 것으로 확인되었지만, 사적행동파와 소극행동파는 부정확한 정보제공과 과장광고 등을 심각하게 생각하고 있었다. 인터넷 쇼핑몰 업체는 불평고객들의 불평해결을 위해 직접적인 접촉을 할 경우 가장 효과적인 불평처리를 할 수 있기 때문에 사적행동파와 소극행동파의 불평행동을 유발하기 위한 노력이 필요하다. 또한 쇼핑몰 관리자의 불친절 및 반응은 심각한 불만족 요인은 아니지만, 배송오류 및 지연과 제품결함과 같은 심각한 불만족요인에 대해서는 직접적인 사과 및 쇼핑몰 관리자의 친절한 태도를 포함하여 현금 환불 등 불평처리를 해야 한다. 그리고 고객의 관점에서 인터넷 쇼핑몰을 보다 편리하고 유용하게 설계할 필요가 있다.

In offline check systems, a client does not have to pay the exact amount. Instead, a client refunds the difference between the check value and the paid amount. In most offline systems, clients can not spend the remainder. But if the refund can be made spendable, it would provide a more convenient payment method. In this paper, we present a new offline system, which allows refunds to be reused as payments. In our system, the shop issues a new check using its private key for the difference. This new check, called the refund check, can be spent in the same way as checks issued by the bank. If the refund check is deposited to, or refunded at the bank, the bank charges the issuer of the check for the amount. The form of a check in this system is much simpler than previous check systems. It also uses a more flexible and efficient denomination method. The refund check is unlinkable to the check used in the payment where the refund check was issued. This system provides coin and owner tracing mechanisms to reinforce controls on illegal use of anonymous checks and was designed with consideration to the atomicity of transactions.

In the area of mobile game, the job of data analysis is very important. As the mobile game market is being expanded, the characteristics of the market have been so much changed, that the contents updating and marketing strategy should be built on thorough understanding and analysis result of the gamers' needs and their play pattern. Thus the importance of the mobile game management system can not be overemphasized. However, in practice, most of the mobile game companies are small scale, and they have intrinsic problem to provide successful game service to user with a dedicated operating team. To overcome these problems, this paper suggests an efficient mobile game management system based on our already developed mobile game. And the effectiveness of our system is illustrated by our case examples such as prompt response to user question or refund request. Our proposed system also played an important role to plan additional contents update, providing scientific data analysis result on user's play pattern and purchase trend.

The development of IT expanded the scale of e-commerce, and grew large Internet shopping malls. As having raised the consumers' interest in overseas direct purchase(ODP) recently, the number and purchasing amount of ODP are constantly increasing. However, consumers need to pay attention to the potential problems which might happen by consumer's damage and conflict, as increasing the consumption through ODP. Because consumer's damages on utilizing ODP happen to the reason such as the trust problem between business and consumer due to the way which traded non face to face, non-compliance of goods delivery, returns, and refunds, and information asymmetry of items, a large number of consumer's damages in a wide range are much more likely to occur nowadays. The purpose of this study is to analyze the current state of ODP, and propose consumer damage's reduction and policy of the government through pre or post scheme for consumer damage's relief and consumer protection. As the compensation for consumer damages is actually inadequate, this study proposed a feasible alternative to the adoption of e-commerce insurance for both aggressive compensation and protection for consumer's damages and risk transfer and sustainable development of e-commerce.
