Background: This study examined the public's perceptions of repeat dispensing as one of the measures to reduce the harmful effects of long-term prescriptions in Korea. Methods: From January 11 to 25, 2021, an online survey was conducted for adults using convenience sampling. A self-developed questionnaire was used. Results: There were 310 respondents, of which 228 (73.5%) preferred repeat dispensing. When considering the additional fee payment, 188 (60.6%) preferred repeat dispensing, and 54 (67.5%) out of a total of 80 chronic disease patients preferred it. It was confirmed that there was a difference in the willingness to repeat dispensing considering the additional cost depending on whether the patient had a chronic disease and the distance from home to the nearest pharmacy. As a result of subgroup analysis for patients with chronic diseases, frequency of outpatient visit, number of prescription days, method of packaging pharmaceuticals, and distance from home to the nearest pharmacy were identified as variables that could well predict the willingness to repeat dispensing considering paying additional fees. The preference for repeat dispensing may vary depending on conditions such as additional cost range, frequency and period of prescription use, disease and patient characteristics, so a careful approach is necessary. Conclusion: It is necessary for the government to consider the introduction of repeat dispensing with interest in the public demand.

블록체인은 물류, 핀테크, 의료, 공공 등 다양한 분야에서 연구되고 있다. 공공정보 소프트웨어 사업에서 개발 산출물과 프로젝트 관리 방법론에서 요청하는 산출물이 일치하지 않아 산출물이 누락되는 경우가 발생하고 대금을 지급하기 위해 별도의 프로세스가 필요하다. 본 논문에서는 이더리움 블록체인을 사용하여 분산 환경을 구성하고 모든 산출물이 승인되었을 경우 자동으로 대금이 지급되게 공공정보 소프트웨어 사업산출물 관리 시스템을 제안한다. 이를 통해 시스템 장애가 발생해도 정상 서비스를 제공하고, 산출물 관리의 투명성과 추적성을 제공하며, 자동화된 대금 지급으로 발주사와 수행사 간 갈등을 줄이고자 한다. 본 시스템에서 산출물의 정보는 블록체인에 저장하고, 산출물은 버전 정보와 이전 산출물 파일의 해시값까지 활용하여 계산된 해시값을 파일명으로 SFTP 서버에 저장한다. 실험을 통해 수행사에서 등록한 산출물의 해시값이 정확한지 확인하고, SFTP 서버에 저장된 산출물의 파일명이 이더리움 블록체인에 등록된 해시값과 같은지 확인하였으며, 모든 산출물이 승인되었을 때 수행사의 이더리움 주소로 대금이 자동 송금되는 것을 확인하였다.

최근 전자지갑, 디지털화폐, 선불포인트, 선불카드 같은 선불전자지급수단의 사용이 점차 증가하고 있다. 선불지급수단은 선 충전, 후 사용이라는 특성이 있다. 본 연구는 선불 충전이 필요한 서비스의 개선에 도움을 주고자, 선불전자지급수단의 온라인 충전 이용의도에 영향을 미치는 요인들에 대하여 기술수용모델을 변형하여 실증적으로 연구하였다. 선불전자지급수단의 온라인 충전 이용의도에 관련된 선행연구가 많지 않아 기존 간편결제와 전자화폐에 대한 연구들을 통해 요인 변수를 도출하였다. 선불 교통카드 사용자를 대상으로 조절효과를 중심으로 온라인 충전의 이용의도를 분석하였다. 연구 결과 독립변수 중에서 '편리성', '보편성', '자기효능감'은 매개변수인 '지각된 유용성'에 정(+)의 영향을 미치는 것으로 나타났다. '지각된 유용성'은 종속변수인 '이용의도'에 유의한 영향을 미치는 것으로 분석되었다. 사용자들의 성별, 인터넷 사용시간, 인터넷 쇼핑 구매빈도, 모바일충전 이용빈도, 교통카드 이용형태 등에 따라서 '지각된 유용성'과 '이용의도'에 조절효과가 유의미하게 나타났다. 시사점으로 선불 서비스의 유용성을 높이는 방향으로 서비스에 대한 개선과 차별화된 마케팅의 필요성을 제안하였다. 다른 요인변수와 조절변수를 추가하여 전자지갑, 간편결제포인트, 디지털화폐 등의 서비스를 대상으로 향후 연구 방향을 제시하였다.

This study aimed to analyze the economic feasibility of the reduction of working safety accidents in stow net fishery through the prevention education to fishing crews. The benefit was evaluated by estimating insurance payment amount that was reduced through prevention education. The decreasing rate of working safety accidents was presumed to follow the experience in Japan. The cost was assumed as the cost of textbook development. Results indicated that IRR was estimated to be 79.9% in case of scenario assuming no additional operating costs while IRR was 56.3% in case of scenario assuming 10% additional operating costs. In addition, the economic feasibility would be secured when annual operating costs increased to 274 million won according to the result of sensitivity analysis.

The buyer must pay the price under the contract and must take delivery of the goods of contract. The buyer's obligation to pay the price includes taking such steps and such formalities under the contract. The remedial system of the rights of the seller is easier than that of the buyer, for the obligations of the former are less complicated. The seller has the right to avoid a contract provided two conditions are fulfilled : (a) the buyer must have committed a fundamental breach of contract, or (b) the additional period for performance set by the seller in the case of non-performance must have expired. A decision is more difficult to take in the case of a delay where there is no fixed-term contract, to clarify the situation the seller may set a Nachfrist. It is essential that the contracting parties in Korea should understand the provisions of CISG.

Necessity of life insurance is stronger for people who feel some anxiety of their health. However, in fact, it is not permitted for them to get a contract, because life insurance stands on the mutual benefit system. Life insurance must be impartial to all applicants. However, it is very reasonable that an applicant, who has high medical impairment like heart infarction or cancer, is rejected, to have a contract by underwriting decision. On the other hand, if his medical impairment is not so severe, we might accept his application by giving some restriction. Numericalratingsystem by hunter-rogers gave us one of solutions to this problem. We can keep impartiality by using more restrictive decision, in order that we demand additional payment to the impairment applicant according to his mortality. We call this system as substandard life insurance. In this system we need detail information about impairments of applicants in order to decide the condition of substandard risks. Therefore, medical examiners are required to have high diagnostic technique.

We investigate a practical method of calculating the impact of multiple domestic energy price change on the final demand, production, the export and import change, the change in the balance of payment of Korean economy. By combining an existing computable general equilibrium (CGE) model with the traditional input-output analysis with two additional assumptions on the price behavior, we provide a cost-effective method of analyzing the impact of multiple energy price changes on the domestic economy. The energy price shock we used in this paper is 0.127% increase weighted by the sectoral productions. The total impacts on price level and GDP are 1.258% and -0.940%, respectively. The impact on the total output (GDP and intermediate goods) is about -1.580%.

Purpose - This study reviews the past studies that have researched Vendor Managed Inventory (VMI) as a well-known supply chain collaboration program. The main goals of this study are to figure out how VMI brings significant benefits to the supply chain system and suggest additional areas that future studies would address to discover the true nature of VMI. Research design, data, methodology - This study conducts literature reviews on numerous studies that have researched VMI. The past studies are classified in terms of several main issues that have been commonly addressed by many researchers. This study also identifies three key collaborative features of VMI, which possibly explain why VMI improves the supply chain performance. Results - This study finds out that most past studies focused on a limited research issues about VMI. Many researchers have considered integrated decision making and information sharing to be key features that enables VMI to improve the supply chain performance. Conclusions - Based on the findings from the literature review, this study suggests that future studies on VMI take account of new research issues and pay attention to cost payment that researchers have rarely addressed.

Mobile agents based e-commerce system has many advantage than traditional e-commerce-information gathering on goods, price settlement and payment, delivery of the goods purchased, and so on. However, due to the security vulnerability that stems from mobile agent's mobility, mobile agents based e-commerce system has additional security problems. Therefore, in order to do e-commerce securely in th system, first of al the security issues on mobile agents must be addressed. It this paper, we propose a mobile agent transfer protocol that provides confidentiality and integrity of mobile agent in transit and mutual authentication for communicating hosts. We further show the security of the protocol against many possible attacks. Also, we suggest the location management mechanism of mobile agents based on the trust center. This mechanism is capable of finding their locations transparently and detecting mobile agent clones.
