Road Sink Phenomenon (RSP) is one of the major issues in South Korea. National and local governments are trying to develop effective preventive measures against the RSP. Developing the policy-oriented RSP management is most important to minimize possible losses induced by RSP. In this study, we employed the Futures Wheel (FW) method to derive influence factors for RSP management. FW method is widely used for predicting future social-environmental condition. In addition, RAND Corporation`s method is used to derive potential strategic agenda based on derived influence factors by FW method. These derived strategic agenda can contribute to develop the policies related with RSP management.

Although lots of safety inspection and precision safety diagnosis have been conducted on concrete retaining wall, there is no comprehensive analysis on the basis of the accumulated data associated with the statistic. Especially, the concentrated management is necessary on the evaluation items that cause critical damages for the efficient performance. In this regard, this study conducted a correlation analysis between the 18 condition evaluation items and defect index for the concrete retaining wall as well as how each item affects the final defect index as much as in the manual. As a result, correlation coefficient between sliding and overturning was 0.601, which means that they have a strong correlation, and the most influential item on defect index is the condition of drainage that scored the 0.750 correlation coefficient. In addition, as a result of regression analysis, the condition of drainage with the 0.683 correlation coefficient has a strong correlation with the defect index. If the condition evaluation items are integrated or readjusted based on the results of the statistical analysis in this study, the more efficient and accurate maintenance will be possible.

본 연구에서는 국내에 활발히 적용되기 시작한 쉴드 TBM 터널의 합리적인 유지관리를 위한 성능평가 기준을 제시하였다. 이를 위해 국내 외 성능평가 기준을 분석하였고, 국내 시공된 쉴드 TBM 터널에 대한 현장조사 및 정밀안전진단 보고서 분석을 통한 변상사례를 조사하여 성능평가 항목을 균열, 누수, 파손, 박리, 층분리 및 박락, 백태, 품질상태, 철근노출, 탄산화, 단차, 볼트상태, 배수상태, 지반상태, 접속부상태, 공동구 상태로 선정하였다. 또한 다중의사결정기법인 AHP 기법을 활용하여 선정된 성능평가에 대한 합리적인 가중치를 산정하였다. In this study, the performance assessment criterion for reasonable maintenance of shield TBM tunnel was presented. The performance assessment items such as crack, leakage, breakage, spalling, exfoliation/detachment, efflorescence, quality condition, exposure of steel, carbonation, faulting step, bolts condition, drainage condition, ground condition, contact section condition and conduit condition were selected by analyzing domestic and foreign performance assessment criterions and investigating segment lining deterioration cases through the site investigation and in-depth inspection analysis result on the shield TBM tunnel. In addition, the reasonable weight using AHP (Analytic Hierarchy Process) were estimated.

Collapse of reinforced earth retaining wall due to improper design and construction is still occurring during construction and operation. While most studies of reinforced retaining walls are focused on the mechanistic behavior, there is little study on the improvement of assessment item, which is used to examine the safety of retaining wall, based on the existed inspection data. This study proposed new weighting factor of assessment item by utilizing multiple regression analysis technique, AHP method, and entropy method for the existed inspection data of reinforced earth retaining wall. Compared to the existed weighting factor, the value and the rank of proposed weighting factors are changed. By applying the proposed weighting factors to the existing retaining walls of 161 sites, fragility region of 47 sites is changed.

Among various methods to build the construction safety, the consecutive improvement by the measuring and evaluating safety management capabilities for the construction participants such as an owner, a contractor, and a supervisor (construction project manager) can be the effective one. Thus, an effective evaluation and grading criteria to provide performance index for the implementation of safety management activities should be necessary. In this regards, the purpose of this study is to verify the adequacy by offering a competency evaluation system for the supervisor's safety capability and by applying the system to some construction sites. The proposed evaluation system was developed on the basis of the principles of safety management & accident prevention, basic elements of safety and health management system, and safety evaluation cases at home and abroad. The trial evaluation showed that the safety management of the construction site is mainly carried out by the contractor and the supervisor's awareness for the safety management is low on the whole. Especially, it is urgent to improve the support system from the supervisor headquarter and to place the dedicated safety management person in the field.

본 연구는 상가 권리금에 대한 임대차인간의 분쟁을 최소화하기 위하여 권리금의 포괄적이고 모호한 규정들을 재개정을 할 수 있도록 정책적 대안을 제시하고자 한다. 첫째,「상가건물임대차보호법」 권리금의 모호한 정의문제에 대해서 각 권리금별 정의를 구체적이고 명확하게 법에서 명기함으로 분쟁의 소지를 최소화 하여야 한다. 둘째, 임대인의 손해배상책임이 아닌 임대인이 부당하게 얻은 이익을 임차인에게 반환하도록 규정할 필요가 있다. 셋째, 임차인의 지위강화는 상대방인 임대인의 계약의 자유 및 재산권을 지나치게 침해할 수 있고, 동법 상 보증금 한도를 넘는 고액의 보증금이 있는 상가임대차의 경우에는 권리금에 대해서는 보호할 필요가 없다. 넷째, 임대계약자는 임대 기간이 종료되거나 1년 6개월 동안 비영리 목적으로 사용되지 않는 한, 임대인의 손해배상 책임이 없음을 명확히 할 필요가 있다. 1. CONTENTS (1) RESEARCH OBJECTIVES This study aims to propose a policy to re-establish a comprehensive and ambiguous regulation of the goodwill value of the commercial building in order to minimize conflict between Lessor and tenant. (2) RESEARCH METHOD As a research method, previous studies and existing common law, case of dispute, precedent were examined. (3) RESEARCH FINDINGS As a result of a policy proposal, consolidation of position of tenants may excessively violate the freedom and property of the leases’ contracts. It is not necessary to protect the rights of the private sector by modifying the private equity principle of the highest-value guarantee. Therefore, it is suggested to amend the clause entitled Provisions for the Protection of Commercial Building Lease Protection Act to ensure the correct legal system. 2. RESULTS The results are as follows. First, the resolution of the goodwill value of the Commercial Building Lease Protection Act shall be categorized by classifying the rights of commercial building to the stipulated Act clearly. Second, Protect the opportunity to recover the same legal rights. There is a violation of the Constitution that infringes on the rights of the owners and violates the principle of personal sovereignty. No liability shall be liable for the lease of the leases even if they refuse to sign the lease contract. The profits obtained by the lerers shall be returned to the tenant. Third, In the same law, there is no need to protect the rights of commercial building in such a way as to exceed the limit of deposit. Fourth, it is necessary to clarify that the owner of the leases is not liable for damages unless the lease ends in a vacancy or a period of use for a non-profit purpose for a period of 1 year 6 months. As a result of a policy proposal, consolidation of position of tenants may excessively violate the freedom and property of the leases contracts.
