Recently, BIM has been widely applying in civil engineering projects centering on the private construction industry in order to establish self guidelines for spreading in practice. However, most BIM technologies and software are based on the architectural projects. In these environments, it is not easy to apply the BIM to a infrastructure field. Even BIM standards with IFC (Industry Foundation Classes) are also focusing on architectural projects. Especially, both private and public sectors do not know about how BIM delivery system should be performed, and how such deliverable should be submitted to the government yet. Thus, we need to analyze an application level of BIM S/W (Software) in real projects and verify their interoperability. Besides, since there are not any common standards that can exchange IFC models for civil engineering projects, we have many issues in converting as-built infrastructure models into IFC and delivering their design documents to the government. Accordingly, this study aims to perform a BIM process with commercial software for real road project after a detailed design process is finished and verify interoperability between diverse BIM software for securing BIM data reliability.

India has accorded a high priority to road infrastructure development through Public-Private Partnership (PPP) and it has set a high target for investment inflows. Yet, it is widely held that road/highway infrastructure has not been developing at required pace and that the road infrastructure projects under PPP have been suffering from several hurdles and delays, thereby affecting project success/failure. This paper is an attempt to analyze the critical success/failure factors of road infrastructure projects under PPP in India. A questionnaire survey was conducted among a sample of the stakeholders of road infrastructure projects to identify the critical success/failure factors during all four major project stages using different approaches. Initially, the critical factors were identified through ranking based on the average/mean score. Later, the conventional RII score was used to identify the critical success/failure factors. Finally, the critical success/failure factors were also identified based on the stakeholder-wise ranking of the factors and their convergence. The assessment revealed that there was a greater convergence across the different methods and also that there was greater consensus among project stakeholder on the critical success/failure factors of road PPP projects.

본고는 문화재 미등록 민가정원의 조영 당시 형태를 각 정원의 원형으로 삼아 미등록 민가정원의 변화과정을 추적하여 정원의 공간적 가치를 규명하고 전통정원의 계승과 변화라는 관점에서 미등록 민가정원의 역사공간적 가치를 논구하였다. 이를 위해 최근 지정문화재의 해제 수량 증가로 인해 정원의 보존 또한 위기에 처해 있는 강원도의 문화재 미등록 민가정원을 대상으로 정원의 공간변화를 통하여 미등록 민가정원의 양상을 규명하고 그 특성 및 가치를 천착하였고 이를 통하여 다음의 결과를 도출하였다. 첫째, 문화재 미등록 민가정원은 집성촌 지역에 입지하여 전통정원의 형태를 계승 유지할 수 있었다. 정원공간은 유교적 철학의 영향으로 공간이 구획되고 정원의 구성요소와 수종 및 식재방식이 달리 나타나고 있었다. 신분적 위계에 따른 정원 구성요소의 사용이 나타났다. 둘째, 대상지 4개소에서 공간의 축소가 지속적으로 확인되었다. 축소된 공간들은 정원공간들로서 도로의 신설과 환경개선 사업으로 정원의 일부가 국가로 귀속되는 현상이 나타났다. 셋째, 대상지 4개소 중 3개소에서 수령 100년 이상의 노거수 8주가 생육하고 있고 정원 구성요소들은 한중일 삼국에서 조선시대와 동시대에 사용되었던 석수조, 취병, 지당 등이 공통적으로 확인되어 전통정원의 역사성을 계승하고 있음을 확인할 수 있었다.

본 연구는 임도사업의 계획과 유지관리 단계에서 임도 관리자 집단의 의식성향을 파악하여 체계적인 임도 정책 수립을 위한 기초자료를 제공하기 위하여 수행하였다. 임도의 계획과 유지관리에 대한 설문조사 결과, 임도 노선의 계획시 고려사항으로는 육림작업, 산지재해 예방, 목재수확 등의 항목에서 높은 중요도를 보였으며, 간선임도에 대한 선호도가 가장 높게 나타났다. 또한 임도 유지관리 작업의 적절성에 대해서는 두 집단 모두 인력 및 예산부족으로 인한 어려움(92.9%)이 있다고 응답하였다. 임도의 개설로 우려되는 주요 피해형태로는 사면붕괴로 인한 인명피해, 사유지 통행에 대한 분쟁 등의 순으로 나타났으며, 현재 실행하고 있는 임도 유지 관리작업의 주요 내용으로는 배수시설의 정비와 노면정비가 높게 나타났다. 임도시설에 대한 주요 보완사항으로는 배수시설, 비탈면 녹화와 안정에 대한 응답이 높게 나타났다.

기존 지번방식의 주소체계로부터 도로명주소체계로의 변환으로 인해 공공 및 민간분야에서 도로명주소의 활용성이 점차 증가하고 있다. 따라서 도로명주소기본도 데이터의 신뢰성이 절실히 요구되며 이는 데이터의 정확도를 뜻한다. 그러나 도로명주소기본도는 작성당시 서로 다른 도면의 사용으로 인해 정확도가 떨어지므로 활용성 또한 미비한 실정이다. 이에 본 연구에서는 각 시도별 도로명주소기 본도의 구축현황을 파악하고, 도로명주소기본도의 위치정확도 오류를 분석하였다. 그 결과 지적현황측량 성과의 RMSE가 수치지형도측량 성과의 RMSE보다 낮게 나타난 것을 알 수 있었으며 향후 도로명주소기본도에 대한 개선방안 제시의 기초자료로 활용될 수 있을 것으로 판단된다.

The 'One Belt One Road (OBOR)' initiative, which was promulgated as part of the enlargement policy along with the advent of Xi Jinping in 2013, is a policy to expand China's political and economic power externally through linkages with neighboring countries. China's overseas port investment plays an important role in the promotion of the 'OBOR' policy from the coast of China through maritime transportation routes from S.E Asia to Mediterranean and Europe. Since China's overseas port investment has been made from several factors such as political, economic, and military motives, it differs in purpose and character from investments made by private companies, such as Global Port Operators(GTO) which consider profitability first. This study aims to address future prospects and implications by analyzing the geopolitics of China's overseas port investment under the 'One Belt One Road' initiative. According to the results, China's overseas port investment is dominated by state-owned enterprises and political and security factors are more important than profitability. China's overseas port investment has been on a large scale in a short period of time, and China has faced with various problems both domestically and internationally. such as debt default, environmental problems, subordination problems from recipient countries and political and military confrontation with great countries such as United States, Japan and India etc.

This research is to analyze the spatial organization of a traditional rural community and its characteristics, the case of Hanbam village located in the north of Daegu city. The conclusions of this study are as follows; 1. The difference between private space and public space in the residential area of Hanbam village is obvious, and these two spaces are organically related each other by means of road. These spaces have some spatial characteristics of organization, such as center, hierarchy and sequence. 2. The private space consists of a residence module and a farming area in the settlement, and it is clearly farmed by the firm fence of rocks and by surrounding roads. Fruit-bearing trees such as Pyrus pyrifolia, Cornus officinalis, Diospyros kaki, Juglans sinensis are planted at the boundary. And most of residences are composed of a building, a inner court and farming fields. 3. The public space for the community mainly functions as ‘a meeting place’for residents, and consists of recreational spaces, ceremonial spaces, community facilities, and social facilities. Among these, Jeong-ja(pavilion), Seong-an Soop(forest) and Dae-chong(building for common use) are of great cultural value as important traditional spaces. 4. Two kinds of road are commonly fecund in the village; spontaneously generated one and planned one. This is straight inner streets and access paths to the village, and that is curvilinear alleys which are connected to Dae-chong, the core of village. Also stone walls and climbing plants on them are major elements of village landscape.

The limited public funds available for infrastructure projects have led governments to consider private entities' participation in long-term contracts for finance, construction, and operation of these projects to share risks and rewards between the public and the private. Because these projects have complicated risk evolutions, diverse contractual forms for each project member to hedge risks involved in a project are necessary. In light of this, Build-Operate-Transfer(BOT) model is considered as effective to accomplish Public Private Partnerships(PPPs) with a characteristic of an ownership-reversion. In BOT projects, the government has used such an incentive system as minimum revenue guarantee(MRG) agreement to attract the private's participation. Although this agreement turns out critical in success of BOT project, there still exist problematic issues in a financial feasibility analysis since the traditional capital budgeting theory, Net Present Value(NPV) analysis, has failed to evaluate the contingent characteristic of MRG agreement. The purpose of this research is to develop real option model based on option pricing theory so as to provide a theoretical framework in valuing MRG agreement in BOT projects. To understand the applicability of the model, the model is applied to the example of the BOT toll road project and the results are compared with that by NPV analysis. Finally, we found that the impact of the MRG agreement is significant on the project value. Hence, the real option model can help the government establish better BOT policies and the developer make appropriate bidding strategies.
