Since the R&D Program for Small and Medium-sized Enterprises started in 1997 as a part of Small and Medium Business Administration, many companies succeeded to carry out the tasks and were charged royalty fees from the government aid program in return. However, some of them were unable to pay a royalty because of their poor financial positions. Failure to pay a royalty also led to adding administrative duties including debt collection and imposing a penalty of participation restriction for other R&D programs. To solve the problems incurred by a failure of royalty collection, a divided payment using a surety insurance was introduced in 2009. That is, the R&D program recipients who were charged royalties issue surety insurance policies and submit them to a collection agency with a plan of divided payment. In this study, we estimate the main benefits of introducing surety insurance for royalty collection. First, we analyze royalty collection results from recipients supported by the R&D program from 1997 to 2006. By doing so, we calculate the main parameters that will be used for estimating the 2011 collection results. Next, besides estimating the quantitative effect, which summarizes an increase of royalty collection via surety insurance, we also analyze various qualitative effects such as simplification of the collection process and expansion of opportunities for participation in R&D programs.

The purpose of this study was to verify whether the endorser effect similar to humans can be created in advertising campaigns based on the artificial intelligence endorser. In particular, considering the characteristics of artificial intelligence, a research model was presented by convergence of consumer innovativeness and anthropomorphism. The results of the online survey of 244 respondents showed that expertise of the artificial intelligence endorser has a positive effect on both brand attitude and purchase intention, but not for trustworthiness while it has a positive effect on brand attitude. Also, the effect of consumer innovativeness and anthropomorphism on brand attitude and purchase intention for artificial intelligence was found. The endorser effect was expanded to artificial intelligence, which is an intangible object, and the existing theory and research results were combined to re-verify it. Theoretical and practical implications for artificial intelligence-based products and services were presented.

This paper considers the optimal periodic preventive maintenance (PM) policy following the expiration of free-repair warranty. We assume that two periodic PM models with random maintenance quality which were proposed by Wu and Clements-Croome (2005) and Jung (2006b), respectively. Given the cost structure to the user during the cycle of the product, we derive the expressions for the expected cost rate per unit time. Also, we obtain the optimal PM number and the optimal PM period by minimizing the expected cost rate per unit time. The numerical examples are presented for illustrative purpose.

2008년부터 시작된 세계경제 위축은 전 세계 해상물동량 감소로 이어져 컨테이너선업계의 불황이 더욱 심화되고 있다. 선사들은 불황을 극복하기 위하여 여러 가지 전략들을 구사하고 있다. 대부분의 선사들은 잉여 선박의 추가투입으로 감속운항을 통해 선박 운영비용을 절감하고 있는데, 이와 같은 시도는 선사입장에서는 비용절감이 되지만 감속운항이 화물의 정시성을 저해하는 요소로 작용하고 있기 때문에 화주입장에서는 불만요인이 될 수 있다. 이러한 상황에서 'M'선사는 "On Time Delivery"를 보증하기 위해서 아시아-유럽항로에서 새로운 서비스인 Daily Maersk Service를 2011년 10월부터 적용하고 있다. 본 서비스는 아시아발 북유럽행 특정 기간 포트구간 수송에서 100% "On Time Delivery"를 보증하고, 또한 매일 화물수탁을 가능하게 한 신서비스이다. 본 연구에서는 업계 1위를 달리고 있는 'M'선사가 감속운항을 하면서도 화물의 정시성을 높이기 위해 실시하고 있는 Daily Maersk Service를 통하여 가격 경쟁과 더불어 서비스 경쟁에서도 우위를 확보하려는 전략이 효과를 나타내고 있는 지에 대하여 사례연구를 통하여 확인하였다.

This study aimed to improve the reliability of the assurance pressure of a gun barrel due to the difference between the US Standard and Korean Standard. In addition, the reliability was found to differ according to the maximum pressure of the Ammunition, so restrictions are expected. During the development of the new bullet, the maximum pressure of the bullet was approximately 3,000 psi higher than the assurance pressure of the gun barrel. To solve this problem, the reliability of the cannon was analyzed when the assurance pressure of the gun barrel increased. First of all, the technical data from overseas were reviewed to check for cases of increased assurance pressure, and tests were performed to determine if it could withstand high pressure through a verification firing test. Finally, the simulation analyzed the stability of the recoil buffer. The study found no abnormal results in all items, suggesting that an increase in the assurance pressure for a gun barrel was possible. This study is expected to be used as basic data for future reliability studies of similar equipment.

발전소 온배수의 원활한 배수를 위한 설계 낙차와 함께 남서해안의 조위변화에 따른 낙차의 이용가능성을 인지하고 소수력 발전 방식과 조력발전 방식의 특정을 동시에 활용하는 해양소수력 발전소를 삼천포 화력발전소 배수로에 최초로 건설하여 운전함으로써 청정 재생에너지 개발 및 $CO_2$ 저감효과 창출에 이바지하고 있다. 본 연구에서는 삼천포 해양소수력 발전소의 운전실적 자료를 토대로 조위 및 방류량의 변화에 따른 해양소수력의 효율 특성을 분석하고자 한다. 해양소수력 발전소의 효율은 방류량과 유효 낙차의 영향을 직접적으로 받기 때문에 관측한 수위 및 방류량, 해양소수력발전소 운전실적 자료를 토대로 효율분석을 실시하였다. 우선, 소수력 가동 이후 배수로에서의 수위 상승이 명확히 나타났으며, 배수로내 위어에서의 흐름구조가 완전월류 상태에서 불완전월류로 바뀌면서 배수로 전체의 수면 불안정성이 크게 증가하였으나, 배수로의 범람이나 순환수 계통에의 큰 영향을 초래할 만한 수준은 아니었다. 성능시험 결과, 최대출력, 평균출력, 최소출력 모든 부분에서 설계 보증치 이내의 값을 보였으며, 효율 또한 설계 보중치를 상회하는 결과를 보였다. CWP 유량 분석결과, 소수력 발전소에서의 유량이 과소 측정되고 있음을 확인하였으며, 최대낙차에서 최대효율을 보이고, 저낙차일 때는 보증치보다 효율이 낮게 나타나는 결과를 보였다. 또한 조위조건을 고려한 유량을 이용하여 산정한 효율 곡선이 보증치와 가장 일치하였으며, 전체 시스템 효율은 비교적 양호한 상태임을 알 수 있었다.
