Recently, the importance of project management has increased due to the scale and complexity of the construction projects. Therefore, this study conducted a survey on construction companies and related public institutions to verify the relationship between the role of the Project Management Office(PMO) and PM leadership for project performance. Based on this, the effect of the PMO role on the project performance was identified and the moderating effect of PM leadership was analyzed. As a result, first, the role of the PMO was found to have an influential on the project performance. Second, the PM leadership was verified to has a moderating effect in the relationship between the PMO role and the project performance. The purpose of this study is to analyze the influential of the role of PMO on project performance in the construction industry to suggest the necessity of PMO in the construction industry and the need to adopt PMO in large-scale construction projects and analyze the moderating effect of PM leadership on project performance.

The construction industry is considered to be a fatal accident industry, accounting for 28.5% of the total industrial accidents in 2017, as the number of industrial accidents in the construction industry has steadily increased over the past decade. So it is necessary to consider introducing Resilience Engineering, which is actively applied to risky industries around the world, to drastically reduce construction accidents. Although Resilience Engineering, which has emerged as the next-generation safety management centered on Hollnagel since the 2000s, claims the importance of strengthening Resilience abilities considering organizational structure and culture, most studies focus only on developing evaluation indicators. The purpose of this study is to analyze the impact of an organization's safety culture on its Resilience abilities in the construction industry. Specifically, it conducted empirical analysis on the impact of safety culture consisting of ‘communication, leadership and safety systems’ on the Resilience abilities(responding ability, monitoring ability, learning ability, anticipating ability), and the mediation relationship between leadership, communication, and safety system. The survey was conducted on construction workers, and an empirical analysis was conducted on the final 154 responses using SPSS 25 and Smart PLS 3. The results showed that the safety system had a significant impact on all Resilience Abilities, and communication had a significant impact on the remaining three except for anticipating ability among Resilience Abilities. On the other hand, leadership has been shown to have a significant impact on anticipating ability only. In the verifying of the mediation relationship between leadership, communication and safety systems, it was found that leadership affects all Resilience abilities by means of safety systems, but communication can only affect responding ability. This study has practical significance in that it suggests the need for policy-level efforts to introduce and apply Resilience Engineering and then expanded the effective safety management assessment of the construction industry in the future. Moreover, the academic implications are important in that the study attempted to expand the academic scope for a paradigm shift in the future as the safety culture has identified its impact on the Resilience abilities.

본 연구는 스마트건설 지원을 위한 드론 활용의 활성화를 위해 RTK 드론 기반의 항공측량 정밀도를 분석하고자 GPS만을 사용하는 방식, GCP를 설치하는 방식, RTK 드론을 이용한 방식의 정사영상의 위치정확도를 분석하였고 사업의 목적과 대상지의 형태에 따른 드론 활용의 기준을 제시하였다. 또한 상용 드론을 이용한 체적기반의 토공량 산출을 2.5D 환경에서 산출하여 기존 방법과 비교해서 드론영상을 효율적으로 활용할 수 있는 방법을 제시하였다. 본 연구로 대규모 건설현장의 작업효율 및 드론 활성화가 기대된다.

『삼국사기』에는 백제가 나당연합군의 침공에 의해 660년 7 월 18일 멸망하였다고 기록되어 있는데, 『일본서기』에는 663 년 9월 7일 주유성(州柔城)이 함락되어 백제의 이름이 끊어졌 고 두 번 다시 선조들의 무덤에도 갈 수 없게 되었다는 한탄이 기록되어 있다.1) 백제의 마지막 수도였던 그‘부여(扶餘)’땅에, 일본제국주의 식민정책의 영구화를 위한 내선일체의 영지를 표 방하는 ‘부여신궁’이 조영되었는데, 이 계획이 어떻게 시작되었 으며 어떠한 과정을 거쳐 계획되고, 공사 진척을 위해 전국적 으로 동원된 인원들과 그들의 봉사일정 등을 언론에 발표된 내 용을 중심으로 시간대별로 살펴보았다. 그리고 국내에서는 사 라졌던 부여신궁 본전 설계도를 입수하여 살펴보고, 현재 입구 가 거의 막힌 채 남아 있는 지하 터널의 용도와 설계도에서의 위치를 추정하여 본다. 기억하기 싫은 뼈아픈 치욕의 역사도 정확히 기억하고, 이를 극복하는 노력이 없으면 되풀이하는 실수를 범할 수가 있다. 실수를 반복하지 않기 위하여서라도 그때 당시를 적확히 찾아 기록하여 후대의 거울로 삼는 것도 의미가 있는 일이리라.
