자율적인 행위자들로서 서로 영향을 끼치며 상호작용하는 선박들을 관제하는 VTSO는 불확실성으로 인한 위험을 극복하기 위해서는 적극적으로 상황을 파악하여 최선의 의사결정을 하여야 한다. VTSO는 항상 미래의 상황을 예측하면서 업무를 수행하여야 하는데 이때 VTSO에게 요구되는 것이 바로 시뮬레이션 능력이다. 시뮬레이션은 삽화기억의 구성적 성격을 활용하는 것으로서 삽화기억의 메커니즘은 미래 계획에도 그대로 활용된다. 본고에서는 반사실적 사고가 시뮬레이션에 어떻게 작동되는가를 살펴보고, VTS 상황에 이를 적용하여 보았다. 특히 반사실적 사고와 시뮬레이션을 통해서 VTSO가 업무역량을 향상시키기 위해서 어떻게 학습하여야 하는가를 고찰하였다.

연구개발활동에 관한 평가를 수행할 때, 가장 많이 사용되어 온 방법이 동료평가(peer review)방법이지만, 최근에는 동료평가가 가지는 문제점을 보완하기 위해 정량지표(bibliometric indicator)의 도입이 다각적으로 검토되고 있다. 여기서는 이를 위해 새로운 정량지표로서 첫째, 동료평가와 정량지표의 점수 배분비율로 각각 $70\%$와 $30\%$로 하고 둘째, 과거 5년 간 가장 우수한 논문 10편만을 대상으로 정량지표를 작성하며 셋째, 각 논문이 게재된 저널이 속한 분야 저널들의 impact factor 순위를 백분율로 적용하여 이에 따른 가중치를 적용하는 방식이 바람직하며 넷째, 논문에서의 저자 역할에 따라 점수를 차등화하고 공동저자의 논문 실적이 주저자의 논문실적에 의해 결정되도록 하는 방식을 제안하고 있다. 이와 같은 정량지표는 과거의 정량지표가 가지고 있었던 한계를 상당 부분 극복할 수 있을 뿐 아니라 동료평가를 보완하는 방법으로 사용될 수 있다.

유역 내에서 효율적인 물관리를 수행하기 위해서는 하천을 중심으로 이루어지는 물 이용량에 대한 파악이 선행되어야 한다. 현재 우리나라에서는 홍수통제소를 중심으로 하천수 사용 관련 허가 및 실적 관리업무가 이루어지고 있으며, 이를 통해 하천수 이용에 대한 관리를 수행하고 있다. 하천수 이용 허가 관련 시설물 중 절반 이상은 농업용수 공급을 위한 시설물이며, 수자원장기종합계획 등 수자원 관련 계획을 살펴보면 우리나라 용수 이용량의 절반 이상이 농업용수 이용량인 것으로 나타나고 있다. 따라서 농업용수 이용량에 대한 파악은 한정된 수자원의 효율적 활용 및 관리 측면에서 매우 중요한 요소라 할 수 있다. 하지만 농업용수 이용량에 대한 모니터링은 거의 이루어지고 있지 않으며, 농업용수 용도의 하천수 취수량에 대해서만 하천수사용실적관리시스템을 통해 월 1회 사용량 보고가 이루어지고 있는 실정이다. 농업용수는 그 특성상 강수 등 기상상황의 영향을 크게 받는다. 즉, 강수량이 풍부할 경우 하천으로부터 인위적으로 취수하는 양은 상대적으로 적으며, 무강우가 오래 지속될 경우 하천수에 대한 의존도가 크게 높아진다. 이러한 농업용수 이용 특성을 고려하여 기상조건과의 관계를 정량화할 경우 농업용수 이용량에 대한 개략적인 추정이 가능할 수 있다. 농업용수 이용량에 대한 추정은 평저수기 및 갈수기 효율적인 하천수 관리 업무 수행을 위해 필수적인 사항이라 할 수 있다. 따라서 본 연구에서는 강수량 등의 기상조건과 농업용수 이용량 간의 관계를 분석하여 제시함으로써 기상조건에 따른 농업용수 이용량 추정 방안을 검토하여 제시하였다. 농업용수 이용량 추정 방안은 상대적으로 강수량의 영향을 크게 받는 논 용수 이용량에 대해서만 검토하였으며, 반순별 이용량을 바탕으로 관계 분석을 수행하였다.

Objectives: This study was conducted to identify factors that affect medical service performance in rural health sub-centers and to develop a method to improve health sub-center performance that takes advantage of these insights. Methods: This study included 1,242 South Korean health sub-centers that had been in operation at least since December 31, 2009 as units of analysis. After adjusting for population differences between areas, the performance of medical service among health sub-centers was analyzed according to medical services performed per person. We performed t-tests, ANOVA, Scheffe's tests and multiple regression analyses. Results: The following were significant variables affecting the medical service performance of rural health sub-centers: number of hospitals and clinics, presence of community health practitioner posts, distance from health sub-centers to main public health centers, distance from health sub-centers to the nearest emergency medical facilities, and proportion of the local population aged 65 and over. In contrast, the proportion of the local population between ages 0-4 and the placement of public health doctors that had already completed their internship were not significant variables. Conclusions: The medical service performance of health sub-centers located in rural areas is significantly affected by local population and health care environment characteristics, and therefore, it is imperative to develop strategies to provide differentiated service based on these factors.

This study examines how the patent results of the University Academic-Industrial Cooperation influence technology transfer. Statistical analysis was performed by using 2013 panel data from the Ministry of Education and Science Technology(MEST) National Research Foundation of Korea(NRF) and the results are as follows. The results show that the patent result factors that have a positive effect on the total number of technology transfers are domestic patent application numbers, foreign patent application numbers, future technology(6T) patent application numbers, science technology patent application numbers. The factors that have a positive effect on increasing royalty are the total number of technology transfers. Domestic patent application numbers, future technology(6T) patent application numbers and science technology patent application numbers have a positive effect on patent results. The results implicate that more research and development is needed for more patents to be applied, that the main focus should be on future technology(6T) and science technology fields, and that effort should be directed at planning negotiation strategies for the term of the contract. However, this study is the need to research, including primary research is so patent performance may be limited in having only been considered in future studies of human and material resources and operating system factors that may be presented to the essential elements of the Industry-Academic Cooperation Foundation this raises.

속력시운전에는 건조된 배의 추진성능이 선주와의 계약속도를 만족시키는가를 확인하는 Acceptance Trial 과, 건조된 배의 추진성능이 모형시험 등에 의한 추정 결과와 맞는가를 확 인하고 다음 배의 설계에 참고하기 위한Performance Trial로 크게 나눌 수 있다. Acceptance Trial로서의 실선시운전은 새로 배를 만들어 선주에게 인도하기 위한 필수의 과정이며, 이 중 에서 저항추진 성능을 검증하기 위한 속력시운전은 가장 중요한 항목중의 하나이다. 선발 조선 국들에서는 실선시운전 및 해석방안을 꾸준히 연구하여 왔고, 표준 수행방안과 표준 해석방안도 이미 확정한 후 여러차례 보완한바 있다. 조선의 역사가 깊지 못한 우리는 이에 대한 깊이 있는 연구는 물론, 이렇다할 시운전 표준수행방안이나 표준해석방법 조차 제시하지 못하고 있는 실 정이다. 특히 국내 조선업계의 실선시운전 해역은 일본은 물론 유럽의 시운전해영들 보다도 해상 상태가 거칠어서 이에 대한 보정방법 개발이 절실히 요망되고 있다. 본 고에서는 이제까지 선진 조선국에서 수행된 중요한 실선속력시운전 내용을 훑어보고, 각국의 표준수행방안을 비교해 보고, 해석방법들의 내용을 알아 본 후, 앞으로의 발전 방향을 모색해 보았다.

For a successful construction project not only construction engineering and project management technology but also economic evaluation technique is required. Design and construction technologies are necessary to receive a project order. However, construction management technology which can be apply from the project initial phase to the project operation and management phase is required to create a benefit from the project. Construction management technology is one of the effective factors for project success. Economical and efficient cost management from the planning phase influences the project success. This study investigated cost flow and cost factors of domestic Sewage Treatment Plant project for systematic analysis of cost items following the entire project phase. Particularly, data modeling based on domestic Sewage Treatment Equipment maintenance cost DB was performed, and maintenance cost estimation trend line is suggested using Monte carlo Simulation Method to decrease uncertainty of actual results DB and for feasibility study.

The leisure boat industry has the potential to become a high-value-added industry in the future. Recently, a study on Korean high-speed leisure boats for fishing was conducted. This study suggests a product configuration model-based shipbuilding cost estimation method for determining the type of leisure boat suitable for mass production, as part of a research for productivity improvement. The suggested estimation method based on the analysis of the leisure boat process and generic YWBS can calculate quantitative and concrete data. By using this method, the cost of building the catamaran-type design ship can be reduced by 17 times, compared to that of the monohull-type mother ship. This implies that the final design of the Korean high-speed leisure boat for fishing will have a competitive price at the actual production stage.

Re-damage is frequently occurring for various reasons, including material factors, external factors, and factors caused by poor construction in concrete cross-section restoration work, so it is necessary to identify the cause and improve it. Cement-based materials are the most commonly used maintenance materials for concrete structures, and in particular, additional cross-sectional restoration work may be carried out due to re-damage such as cracks and excitement due to dry contraction of the repair material. In this study, a basic study was conducted to identify the characteristics of concrete while diversifying the maximum dimensions and assembly rate of thick aggregates to examine the effects of using thick aggregates in repair materials. As a result, the slump of concrete increased as the maximum size of thick aggregates increased, and the amount of air content was measured 1.88 to 2.35 times higher in the mixing using aggregates with a maximum aggregate size of 5 mm or more compared to the mixing group with a maximum aggregate size of 10 mm or more. It was found that compressive strength was greatly affected by the performance rate of thick aggregates. The compressive strength was measured the highest in the mixture using thick aggregates with the highest performance rate of 20 mm, and the compressive strength of the mixture with the lowest performance rate was more than 45%. As a result of the dry shrinkage measurement, the dry shrinkage was the lowest as the performance rate of the thick aggregate increased according to the change in the maximum dimensions and assembly rate of the thick aggregate, and the lowest performance rate was the largest in the mix. Through this study, it was confirmed that adjusting the particle size by diversifying the maximum dimensions and assembly rate of thick aggregates used in concrete structure repair materials can improve strength and workability and reduce dry shrinkage.
