현재 정부는 지하수 기초자료의 구축을 위해 '지하수 기초조사', '지하수 이용실태조사' 및 '지하수시설 전수조사'를 실시하고 있다. 지하수 기초조사는 「지하수법」 제5조(지하수의 조사)에 근거하여 실시되는데, 1990년 시범사업을 시작으로 30여 년 가까이 사업을 추진하고 있으나, 예산 및 인력 부족 등의 이유로 전국 전체에 대하여 조사를 완료하지 못하고 있는 실정이다. 지하수 기초조사 및 보완조사의 체계적인 시행을 위해 지하수관리기본계획에 지하수 기초조사 및 보완조사의 추진경과와 향후 계획을 비롯한 지하수 조사에 관한 사항을 포함하는 방안이 필요해 보인다. 지하수 이용실태조사는 「지하수법」 제17조(지하수의 관측 및 조사 등)제6항에 근거하여 시장·군수·구청장이 관할구역별로 조사·제출한 자료를 기반으로 작성되는데, 조사 결과에 대한 신뢰성 확보에 어려움을 겪고 있다. 각 지자체에서는 전문인력 및 예산 부족 등의 이유로 관련 규정에 따라 이용량을 산정하기보다는, 지하수 시설의 취수계획량을 이용량으로 대체하는 경우가 많기 때문이다. 지하수 이용실태조사 결과의 신뢰도를 높이기 위해서는 지자체 지하수 업무 담당자에 대한 교육 및 자료의 보완·개선 절차가 필요하다. 지하수시설 전수조사는 관정, 집수정, 지하댐 등 현재 사용 중인 시설과 더불어 사용하지 않거나 방치된 시설, 허가·신고하지 않고 사용하는 불법시설 등 지하수 관련 모든 시설을 조사한다. 과거 2009년부터 2014년까지 6년에 걸쳐 지하수시설 전수조사를 실시한 바 있으나, 아직까지 법적 근거가 마련되지 않은 상태이다. 불용공(不用孔)의 처리 및 불법시설 양성화 등을 위해 지하수시설 전수조사는 법적 근거와 조사의 방법, 대상 및 시행 절차 등에 관한 세부규정을 마련할 필요가 있다.

전 세계적인 기후변화로 인해 홍수가 발생하는 빈도가 상승하고 있으며, 도시화가 발달됨에 따라 재산 피해 금액도 증가하는 추세이다. 이와 같은 홍수피해를 저감시키기 위하여 수공 구조물의 보강 및 설치와 같은 효과적인 구조적 대책이 필수적이다. 구조적 대책의 경우 예방차원의 재난관리를 위하여 치수 사업 전/후의 경제성을 평가해야 하는데, 국내에서는 개선법과 다차원 홍수피해 산정법(MD-FDA, 이하 다차원법)을 활용하여 정량적인 경제성 평가를 수행하고 있다. 그리고 다차원법의 경우 공간정보자료인 토지피복도를 활용하기 때문에 침수된 건물을 각각 산정해줌으로서 보다 정확한 경제성 분석을 실시할 수 있지만 산정 절차가 복잡하여 시간이 오래 걸리는 단점을 지니고 있다. 따라서 본 연구에서는 개선법과 다차원법의 단점을 보완하고자 격자단위 공간정보를 활용한 건물피해 산정방법을 제안하고자 하였다. 국토정보플랫폼에서는 100m×100m 격자 자료를 제공해주고 있으며, 각각의 격자에는 단독 주거, 공동 주거의 공간정보 자료가 구축 되어있다. 이러한 격자자료와 홍수범람지도를 중첩하여 격자 단위 홍수 피해액을 산정함으로서 절차를 간결하게 할 수 있다. 또한 본 연구를 통하여 추정된 피해 금액과 비교적 정확한 홍수 피해액을 추정하는 기존 다차원법의 피해 금액을 비교하여 격자단위 공간정보를 활용한 건물피해 산정방법을 평가하였다. 본 연구를 통하여 개발한 방법을 사용하게 된다면 경제성분석 결과가 과대 산정되는 개선법을 보완할 수 있으며, 계산과정이 복잡하여 실무에서의 적용성이 부족한 다차원법의 문제점도 보완할 수 있을 것으로 판단된다. 또한 신속한 피해액 추정을 통하여 홍수 피해를 예방하는데 필요한 치수사업을 빠르게 선정함으로서 후속 피해를 신속히 예방할 수 있을 것이다.

Schedule control is an exceedingly fundamental and important construction business function. Even though enormous research efforts have been exerted in this area, there has been no comprehensive and quantitative study exploring detailed cost control practice of construction companies in terms of practical patterns and trends. In this context, this paper surveyed the patterns and trends of schedule control practice of Korean general contractors. Schedule control process as compared to schedule reduction is focused in this paper. The variables for practical schedule control process were identified first. A survey questionnaire was then developed and used in order to collect data from Korean general contractors. Survey results analyzing responses from 45 companies show that scheduling processes in practice have been significantly enhanced in terms of software tools, manuals, and capabilities of engineers.

The most of domestic bridge has an used life under 30 years, Future maintenance budgets can be expected to increase. However, because of bridge maintenance budgets are limited, demand for asset management being performed to achieve required performance within available budget is increasing. To perform effective asset management of bridges should be made the best use of information to occur in all phase of construction project. Therefore, the development of system and DB is required to support asset management by effective information management. The objective of this study is the development of the BIM-based bridge asset management model. Through previous research survey, BIM capabilities and asset management components were established and mutual linkages were examined. Bridge asset management model was composed of alternate assessment model. In addition, BIM-based asset management model was performed case studies to verify feasibility and applicability. The proposed model can be applied to a current bridge maintenance procedures and supported to perform effective bridge maintenance tasks within a limited budget.

This study aims to critically consider the local cultural policies of the government and local governments by village mural. Village murals, which began to be painted in the late 1990s, have been a nationwide cultural phenomenon for decades. In particular, it was consistently used as an important element of various local cultural policies implemented by the government and local governments. The government and local governments have been working on the project for two purposes: 'improving the residential environment' and 'activating tourism' but it has largely focused on 'activating tourism'. This study grasped the concrete status of major village murals across the country through field surveys, one of the case study methods. Also, through the analysis of official documents, the government and local governments operating in the village mural project were analyzed for the policy basis and administrative management plan. As a result of on-site surveys, most of the village murals across the country had problems such as uniform subject matter, low level representation, and poor follow-up management. This is partly based on the experiences and abilities of organizations and artists who participated in the village mural project, but fundamentally, it is due to the projects of the government and local governments that focused on short-term visual tourism rather than long-term improvement of the residential environment. It was confirmed that the projects of the government and local governments were carried out through vertical integration and that there were problems in the actual work, such as requiring specific topics, subject matter, designs and colors. As a result, the village murals 'objectify' the residents and 'romanticized' the place, resulting in a unified visual representation. Therefore, this study suggests that the administration and accounting should be strictly managed, but in actual work, the vertical integration structure should be eased by simplifying various documents and procedures, as well as rich cultural understanding of the target place, selection of various topics, and original subject matter and expressions.

In Korea, the construction industry has been growing quantitatively because of its aggressive advances into overseas construction market and the Korean government's housing policy. Moreover, visions and goals such as 'construction industry promotion build up plan' have recently been promoted by the government while new strategic growth focused on competitiveness is gaining interests among the industry. However, there are a few problems in the construction performance. First, the specific performance measurement indicator or skills for the construction industry are hardly found in Korea. Currently, the finance or overall management system in the construction business are used as indicators to measure performances in not only the construction industry but all industries including the manufacturing industry. The government, the industry and universities recognized the need for the performance measurement indicator and skill and have developed and actively studied on them.

EPC companies to continue operating overseas, it is increasingly becoming apparent that risk is no longer something to be avoided but a subject to be managed. During the bidding stage, the requirements, specifications and project line items within the bid package must be studied in details to analyze the various risk factors in order to avoid cost overruns. However, reviewing vast quantities of bidding documents is time consuming and labor intensive and is not an easy task and this is where automated information technology can help. For this study, I have constructed an ITB analysis model based on Watson AI that can analyze and apply vast amount of documents more effectively in a short time. Configuration of the Watson Explorer AI architecture for AI-based ITB risk management model research, the selection of learning procedures and analysis subjects, and the performance evaluation criteria were defined, and a test bed was constructed to conduct a pilot research. Consequently, I verified the effectiveness of the analytical time reduction and the quality of its results and VOC operations by professionals.

In Korea, the number of preservation and management entities to connect the traditional cultural heritage to next generations is rapidly decreasing. Building an infrastructure to pass on traditional cultural heritage to the next generation and to pay attention to the preservation and management of the next generation is important including the 'Seowon', a World Cultural Heritage listed by UNESCO. This study is based on the laws that regulates the preservation and support of traditional cultural assets and 'Seowon, through Big Data analysis techniques. The main keywords in each law were extracted, schematized, and a mutual Word Network was constructed and policy advice was derived. As policy advice, it is necessary to establish and implement policies to nurture and support businesses specialized in the region for the preservation·utilization, preservation·management and preservation·support of Seowons.
