정부가 사회간접자본시설(SOC)의 민간투자를 활성화하기 위하여 최소운영수입보장제도제도 즉, MRG 제도를 시행하여왔으나 민간투자업자의 이익을 과도하게 보장하고 있다는 측면에서 많은 비판이 있었으며 이로 인하여 점차적으로 이 제도가 축소되다가 2009년 10월에는 MRG 제도가 폐지되고 정부고시 민간투자사업에는 투자위험분담방식으로 변경되었다. 이로 인해 현재 수익형 민자사업(BTO)에 대한 투자는 상당히 위축되어 있는 상태이다. 최근에 다시 민자사업에 대한 투자를 활성화시키기 위하여 민간투자사업의 새로운 방식인 표준사업운영비 지원방식, 최소비용지원 방식 등이 제안되고 있으며 본 연구에서는 민간투자사업의 최소운영수입보장제도(MRG-Minimum Revenue Guarantee)방식으로 협약이 체결되어 있었던 부산시 부산항대교를 사례로 하여 최근 연구되고 있는 최소비용지원방식(MCS - Minimum Cost Support)에 의한 수익성 분석모형을 적용하여 MRG 방식과 비교ㆍ분석과 아울러 민간투자사업의 추진 방안과 효과를 제시하였다. v1. CONTENTS (1) RESEARCH OBJECTIVES The Korean government once institutionalized MRG(Minimum Revenue Guarantee) system the act on private participation in Social Overhead Capital(SOC), which minimizes the investment risk of a public private partnership project. However, this act was severly criticized for protecting private finance investors abruptly large profits. As a result, MRG was gradually scaled back, and was finally repealed in October, 2009. Since then, the government has changed MRG into Investment Risk Sharing only for governmentally notified public private projects. In consequence, many private finance investors projects are currently decreasing and declining in a substantial amount. Recently, new investment systems were proposed, which is Minimum Cost Support in order to promote the public private investment. The purpose of this study to analyze on between Minimum Revenue Guarantee and Minimum Cost Support(MCS). (2) RESEARCH METHOD To archieve our research objectives data was collected from Busan port grand bridge contract agreement. This study carried out an analysis of MRG model and MCS model. (3) RESEARCH FINDINGS The comparison and analysis of MRG and Minimum Cost Support is presented, and the strategies of a public private partnership project and its effects are proposed. 2. RESULTS It is proven that MRG is better than MCS under the traffic volume ratio of 40%. In short, MCS is a better method and can increase actual traffic volume ratio from 40 % to 100%

The study aimed to identify the process change in ‘East Asian History’ curriculum for high school in ‘2015 revised curriculum’ by comparing to previous curricula, ‘2007 revised curriculum’ and 2009 revised curriculum. In the ‘2007 revised curriculum,’ ‘East Asian History’ was first implemented for high school in 2012, which continued throughout the ‘2009 revised curriculum’ that was applied from 2014 to ‘2015 revised curriculum’ that will be applied from 2018. As a result of comparing the two pre-existing curricula, Seemingly, ‘2015 revised curriculum’ achieved its goal of lightening the burden on class, but it is considered that learning elements of the previous two curricula were almost directly reflected and caused no big difference. Also, in the process of reducing external learning elements, imbalanced chapters were created or the history of Vietnam was reduced. The fact that the new ‘2015 revised curriculum’ has no big difference compared to existing curricula can be necessary for soft landing of the of curriculum of ‘East Asian History’. However, this also means that reorganizing existing history curriculum had little change except for specific periods. The advantages that approach by topic of ‘East Asian History’ showed different characteristics from other history subject in previous curricula and that it provided the cognition of learning history beyond nationalistic perception of history should be more magnified by making progressive new attempts. This will clarify the sequence in history education and make history education more meaningful. Therefore, they study investigated a few issues to be considered in ‘East Asian History’ in 2015 revised curriculum and in newly developed history curriculum in the future through several suggestions. It is expected that ‘East Asian History’ that has presented a new frame in the Korean history education serves as a useful tool for peace and coexistence in the East Asian region through continuous development while the existing frame is stably maintained.

A case of repeated bovine abortion caused by Neospora caninum is described. The 3-year-old Holstein cow, which was seropositive to N caninum antibody by indirect immunofluoresent assay, aborted consecutively within a 10-month period. Two fetuses of 6- or 5-month of gestation were aborted in June 1996 and March 1997, respectively. Histologically, multifocal necrotizing encephalitis, nonsuppurative periportal hepatitis, myocarditis, and myositis were observed in both fetuses. Tachyzoites or tissue cysts detected in the brain, heart and liver were positive to N caninum but negative to Toxoplasma gondii by immunohistochemical method. The results of our study demonstrate that repeated abortion due to N caninum actually occurs in Korea. This is believed to the first report of repeated abortion associated with N caninum in Korea.

We consider a new classification method(DnDclass) combining two classification rules based on $L_1$-distance(L1DISTclass) and $L_1$-data depth(L1DDclass). To investigate characteristics and to evaluate the performance of these classification methods, we use simulation data in various settings. Through this simulation study, we can confirm that the new method, DnDclass, performs relatively well in many cases. $L_1$-데이터뎁스를 이용한 분류방법(L1DDclass)과 관측치들 사이의 $L_1$-거리를 이용한 분류방법(L1DISTclass)의 특징을 살펴보고, 이 두 방법을 결합한 새로운 분류방법 (DnDclass: Distance and Data-depth based classification)의 효용성을 소개하고자 한다. 모의실험을 통해 세가지 분류방법의 결과를 비교하고 제안된 분류방법이 다양한 경우에 더 효과적일 수 있다는 사실을 확인한다.

The Neospora sp. was isolated from the brain of 1 calf via continuous in vitro cultivation in Vero cell. Neospora tachyzoites were observed 45 days after inoculation of the homogenized brain suspension into the Vero cell. The isolated parasite (named tentatively as NCKB-1) was morphologically and ultrastructurally similar to the previously reported Neospora sp isolated in cattle (BPA-1, JPA-1). A comparison of the antigenic reactivity of cultivated tachyzoites with polyclonal antisera to Neospora caninum and Toxoplasma gondii confirmed that this protozoal isolate was similar to N caninum. This is the first report of successful isolation of Neospora sp from cattle in Korea.

노상토의 변형특성은 포장설계에 있어서 매우 중요한 기본적인 입력물성치다. 노상토의 탄성계수를 실험적으로 결정하기 위해서는 많은 노력이 필요하다. 포장 단면이 간단하거나 중요도가 낮은 도로 설계의 경우 시험적인 탄성계수 결정이 과다한 비용을 요구하게 된다. 보다 간편한 대체시험 또는 기초물성치로부터 탄성계수를 결정하는 다양한 경험모형이 제안되어 있다. 본 연구에서는 7종의 국내 노상토에 대한 시험을 수행하였다. 국내 노상토의 경우 강도특성과 변형특성의 밀접한 상관성을 확인 하였으며, 경험적 상관모형을 제안하였다. 점착력과 낮은 구속응력단계에서의 탄성계수는 매우 큰 상관관계가 있었다($r^2=0.93$). 제안된 상관모형을 적용하여 강도특성으로부터 추정된 탄성계수와 시험을 통하여 측정된 탄성계수의 비교에서 결정계수($r^2$)는 0.75로 나타났다. Deformational characteristics of subgrade soils are very important input parameters for pavement design. It is necessary to make an amount of effort to estimate experimentally the modulus of subgrade soils. In case of designing simple (or lower level) pavement section, the estimation of the modulus based on experiments must cause an excessive cost. It has proposed various empirical correlation models to estimate the modulus from basic properties of the materials or more simple alternative tests. Seven subgrade soils in Korea were tested in this study. It was founded that the deformational characteristics of subgrade soils in Korea has a close relation to strength characteristics, the empirical correlation model was proposed. There was a close relation between cohesion value and modulus at low confining stress ($r^2=0.93$). By comparing with the measured modulus and the modulus determined by proposed correlation model from strength characteristics, the value of the coefficient of determination ($r^2$) is 0.75.
