The use of mobile payment services has recently increased in South Korea. Mobile payments allow consumers to purchase items digitally, using a mobile card in an app affiliated with a payment service. This study explores the predictors of intention to adopt mobile payment services. The study employed an A(affective)-B(behavioral)-C(cognitive) model with two antecedent variables: cognitive (perceived usefulness, perceived risk, perceived ease of use, and perceived herding behavior) and affective (satisfaction with the status quo, innovation resistance) responses. An online survey of 405 non-users of mobile payment services aged 20 to 49 years was conducted. The study used SPSS 23.0 for descriptive analysis and Amos 23.0 for confirmatory factor analysis and structural equation modelling. The results are as follows. First, perceived usefulness, perceived risk, and perceived herding behavior significantly influenced innovation resistance. Second, perceived herding behavior significantly influenced subjective norms. Third, innovation resistance and subjective norms significantly influenced the intention to adopt mobile payment services. The findings suggest that the A-B-C model can be useful in understanding consumers' adoption and resistance behaviors and that cognitive and affective responses are important antecedent variables affecting the decision to adopt mobile payment services.

The purpose of this research is to investigate the factors affecting Thai commercial bank users' behavioral intention towards QR code payment system via mobile banking applications. The researchers conducted the study based on quantitative research approach. Non-probability sampling method such as the quota and convenience sampling was applied as sampling technique. A self-administered questionnaire was distributed. The data was collected from 1,800 respondents living in Bangkok, who have had an experience with QR code payment system with the top-three mobile banking applications in Thailand. This study concentrates on confirmatory factor analysis and structural equation modeling as a statistical tool to examine the data, model accuracy, and influence of critical variables. In addition, the researchers applied the first-order and second-order techniques to examine the relationship between constructs. Adoption readiness and perceived risk were second-order constructs. The results reveled that compatibility has an impact on attitude towards QR code payment. Moreover, adoption readiness, compatibility, attitude, and personal innovativeness are statistically significant that impact behavioral intention towards QR code payment. The strongest antecedents of behavioral intention were compatibility, attitude, adoption readiness, and personal innovativeness, respectively. Surprisingly, perceived risk and perceived trust do not statistically have a significant impact on behavioral intention towards QR code payment.

모바일 소액결제 서비스는 소액결제 시장에서 최근에 새롭게 등장한 혁신 기술이다. 다른 결제 수단들에 비해서 사용되기 시작한 기간은 얼마 되지 않았으나 인터넷 혹은 모바일 상의 수많은 온라인 기업들에 의해 가장 널리 사용되고 있는 결제 수단이기도 하다. 하지만 전자결제와 관련한 기존의 연구들은 대개 결제 프로세스 그 자체에 많은 관심을 가져 왔다 그러다 보니 자연스레 프로세스 자체의 보안성이나 견고함 등에 연구의 초점이 맞추어지게 되고 상대적으로 전자결제 서비스가 가지고 있어야 하는 사용자 편의성이나 효율성 등에 대해 행동과학 측면에서 접근한 연구가 부족한 실정이다. 본 논문에서는 모바일 소액결제가 내재하고 있는 어떠한 특성요인이 서비스 사용자/비 사용자의 판명에 영향을 미치는지를 그 영향력의 크기와 함께 규명해 보고자 한다 이를 위해 Rogers 의 기술수용모델과 전자결제가 가지는 특성변수들을 함께 고려한 모형을 설계하였다. 결과적으로 사용용이성(ease of use), 취득용이성(convenience), 관측성(observability)등이 사용자/비 사용자 구분에 유의한 영향력을 미치며, 안전성(security)은 user status에 영향력이 없는 것으로 판명되었다.

Purpose - Although remittance payment in international trade settlements has played a bigger role in recent years, scant research is being done. This study is to zero in on analyzing determinants of international trade payments focused on remittance by constructing a payment prediction model. Design/methodology - This study categorizes the types of trade payments into advance remittance, post remittance, linked remittance, letter of credit, and mixed payment, and analyzes these after constructing a logit model. For empirical analysis, 147 survey data were collected for export manufacturers in Korea, and binominal logistic regression analysis was used to analyze the type of payment method the exporter chooses for trade transactions. Findings - The likelihood of choosing advance remittance increased as the exporters had non-recovery experiences with payments, and decreased as the market power of importers increased. The possibility of post remittance increased when the export amount was large and the character of the buyer was reliable. In the case of linked remittance, it was highly likely to be selected when payment efficiency was important in trade settlement. In addition, when competition among companies in the global market is intense and market uncertainty is high, the possibility of using a letter of credit decreases. It was also found that the greater the export amount, the greater the possibility of choosing advance remittance, and even if the transaction period was longer, exporters using a letter of credit continued to use it. Originality/value - Despite the high proportion of remittances in international trade settlements, it has been hard to find studies that reflect the practical characteristics of remittances. This study classified the types of remittance into advance remittance, post remittance, and linked remittance, and built a trade payment prediction model by adding a letter of credit and mixed payment. In addition, the originality of this study is recognized in that a logistic model was constructed and meaningful results were derived.

This study was conducted to analyze the medical charges of the elderly dementia inpatients, to identity their characteristics, and there by to evaluate feasibility of the per diem payment system for the patients. Data on medical charges of the patients were collected from the National Federation of Medical Insurance and sample hospitals from October through December 1997. The data were analysed in order to find the characteristics and test hypotheses postulated. The results are summarized as follows; Firstly, there was no difference statistically in between disease groups and between the dementia inpatients belonging to each disease group. Secondly, the amount of the non-insurance medical charges of the elderly dementia inpatients is considerably high compared to the insurance medical charges paid by the patient, which implies that some measures are to be prepared by the Government. Finally, medical charges per inpatient day of the dementia patients are not different statiscally by sex, by age group, and by disease group. This result supports the feasibility of the per diem payment system for the elderly dementia inpatients.

In order to suggest the strategies for participation in the PPS(Prospective Payment System), analyses were performed based on variations in utilization pattern and changes in revenues of hospitals in 10 selected KDRGs. The data was collected from the claims data of a tertiary hospital in Kyunggido from September 1, 1995 to August 31, 1996. The studies consisted of 1, 718 inpatients diagnosed for lens procedures, tonsilectomy &/or adenoidectomy, appendectomy with complicated principal diagnosis, Cesarean section, or vaginal delivery without any complications. The resources used in each KDRG were measured including average length of stay, total charges, number of orders, intensity of medical services, frequencies of medical services, the rate of non-reimbursable charges, and the rate of non-reimbursable orders. Then, the changes in hopital revenues due to the composition of medical fee schedules under the PPS were estimated as follows: 1) The variations in average lenght of stay, total charges, number of orders, the intensity of medical services, the frequency of medical services, the rate of non-reimbursable charges, and the rate of non-reimbursable orders among the 10 KDRGs were comparatively small. 2) The average lenght of stay was the longest(6.0 days) for appendectomy with complicated principal diagnosis, while it was the shortest(2.1 days) for two vaginal deliveries. Statistically differences existed in the average length of stay among physicians and among the dates of admission in several KDRGs. 3) The total charges were the highest for lens procedures(1, 716, 000 won), while the lowest charges were for two vaginal deliveries(558, 000 won). Statistically differences in the total charges were found among physicians in several KDRGs: however, there were no differences with the dates of admission. 4) The number of orders was the greatest(155) for appendectomy with complicated principal diagnosis, while it was the smallest(75) for the two vaginal deliveries. Statistical differences in the number of orders did not exist among physicians in the KDRGs. 5) Significant differences were found in the intensity of medical services, and in the frequency of medical services among physicians in the KDRGs. 6) The rate of non-reimbursable charges for each KDRG was not related to the rate of non-reimbursable orders. The rate of non-reimbursable orders was the highest(36.0%) for lens procedures, while the lowest rate(11.6%) was for appendectomy with complicated principal diagnosis. The rate of non-reimbursable charges was the highest(39.4-39.7%) for vaginal deliveries, while the lowest rate(13.1%) was for tonsillectomy &/or adenoidectomy(<17 ages). 7) If the physician's practicing style were not change under the PPS, the hospital revenuses could be increased by 10%, and the portion of patient payment could be decreased by 1.4-22.4%. However, the non-reimbursable charges for showed little change between two reimbursement systems. Based upon the above findings, this hospital could be eligible for participation in the PPS(Prospective Payment Systm). However, the process of diagnosis and treatment should be standardized, inentifying methods to reduce cost and to assure quality of medical care. Furthermore, consideration should be given to finding ways to increase patient volume.

International transactions have the threat of non-payment by the buyer or non-performance by the seller. Parties tend to search for additional means of securing performance and payment beyond the mere agreement in the contract. Such security may be achieved by means of a letter of credit. When contracting parties have agreed to pay by means of a letter of credit, the buyer's bank takes upon itself the obligation to pay the purchase price when the seller tenders the documents that are stipulated in the letter of credit. The documents must comply strictly with the terms of the credit.. The documents play a crucial role in letter of credit transaction. The principles of abstraction, separability and strict compliance governing the letter of credit transaction are considered. The concept of fundamental breach of Article 25 CISG was discussed. This article examines whether a failure to deliver documents conforming to the terms of the letter of credit can constitute a fundamental breach of the sales contract as defined by Article 25 of the CISG by the seller and thereby enable the buyer to avoid the contract. For letter of credit transactions it should be accepted that the delivery of non-performing documents constitutes a fundamental breach, if the result of this breach is that the bank refuses to pay the price for the goods. On the other hand, in the interpretation of Article 25 CISG, it should be noted that if the parties have agreed to payment by means of a letter of credit, they have simultaneously agreed to apply the strict compliance principle to the delivery of documents in the sales contract. Finally the parties should ensure that inconsistency between the requirements under the documentary credit and the requirements under the contract of sale is avoided, since the buyer may be in breach of his payment obligation if the seller cannot get paid under the documentary credit when his documents conform with the contract of sale.

현재까지 서울 오피스 시장의 경우 관례적으로 고정된 보증금/월세 비율로 인해 보증금에 대한 이론적인 분석의 여지가 없었다. 하지만 본 연구는 글로벌 스탠다드인 점유비용의 개념을 도입하여 오피스 임대시장의 월세 미납 리스크에 대한 분석을 시도한다. 또한 정보비대칭 상황에서 보증금의 수준이 임차인의 역선택 문제를 해소하는 수단으로 사용될 수 있다는 Benjamin, Lusht, and Shilling(1998)의 견해에 따라 본 연구는 정보비대칭 상황인 서울 오피스 시장을 대상으로 보증금과 월세의 수준이 어떻게 정보비대칭 문제를 해결하는지 검증하고자 한다. 실증분석 결과 오피스 임대인들은 월세 미납 리스크를 헤지하기 위해 약 9%의 리스크 프리미엄을 점유비용에 부과하는 것으로 나타났다. 이러한 결과는 오피스 임대시장에서 보증금 및 월 임대료의 운용수익률을 산정할 때, 임차인이 가지는 월세 미납 리스크의 반영 수준을 추정할 수 있게 한다.

에이전트 기반 이동 컴퓨팅 환경에서 전자 상거래를 구현하기 위해 가장 필요로 하는 것은 안전한 지불 구조를 제공하는 것이다. 본 연구에서는 불확정 전송 기법 1,2 을 사용한 비대화형 엔티티 인증 기법과 Horster 기법 4,5 을 기반으로 메시지 복원 기능을 제공하는 공정 은닉 서명 기법을 제시한다. 또한 이를 직접 Brands가 제시한 오프-라인 전자 지불 시스템 3,6 에 접목한다. 인증 단계가 비대화형으로 수행되므로 이동 엔티티 인증에 효율적이고, 메시지 복원 기능을 갖고 공개 검증 기능을 제공하는 은닉 서명을 적용하기 때문에 카운터 방식을 사용한 스마트 카드 기반 전자 지불 시스템 6 에 효과적으로 적용할 수 있었다. 전자 화폐에 대해서 신뢰 센터에 의한 공정성 검토 기능을 추가로 제공하므로 전자 지불 시스템의 신뢰성을 향상시킬 수 있다.Abstract The primary requirements for realizing the electronic commerce in agent based mobile computing environments are to implement the compatible secure payment framework. In this paper, we propose both the non-interactive entity authentication scheme that is combined with oblivious transfer protocol 1,2 and the message recovery fair blind signature based on Horster scheme 4,5 . And these techniques are directly applied to the Brand's off-line electronic payment system 3,6 . As the authentication processes are done by non-interactive manner, we can also get efficiency for mobile entity authentication. Additionally, as the used signature scheme provides a message recovery function with publicly verifiable properties, it is efficiently applicable to a counter based off-line electronic payment scheme 6 based on the additional device like smart card. Therefore, we can enhance the reliability of proposed electronic payment system based on the publicly verifiable fairness in its electronic cash by a trusted judge.

Background: The purpose of this study is to investigate family caregivers' opinions about out-of-pocket payment for long-term care (LTC) facilities, and find the differences in the opinions for family caregivers of all different levels of income. Methods: We used the data of the study on out-of-pocket payment in national long-term care insurance, including 1,552 family caregivers with the elderly in long-term care facilities. Results: The average out-of-pocket payment per month was 511,635 Korean won and distributed from 230,750 to 1,365,570 Korean won. The amount of out-of-pocket payment might be affected by not co-payment but the cost of non-covered service. There were differences in them for family caregivers of all different levels of income. Opinions were surveyed about 5 issues. By levels of income, there were differences in their opinions about 3 issues, the financial burden on LTC, the necessity of reducing out-of-pocket payments, and to be willing to pay more for a high quality service. But there were not different opinions about the interruption of LTC service and staying with LTC facilities. Conclusion: These findings suggest that the range of out-of-pocket payment for LTC facility is wide and it can be a burden to lower income group. It should be to prepare the policies to ease the financial burden and support the appropriate LTC use.
