Based on the previous year's statistics, 37% of buildings in South Korea are aged over 30 years. As the number of the aging buildings increases, so does the need for maintenance. Building maintenance involves a significant number of works; the work of 'maintenance manager' accounting for the largest part. Currently, the maintenance history record is mostly in drawing or handwritten form which makes reviewing the data highly time consuming. Therefore, to improve the convenience of maintenance works and optimize historical data management, the existing maintenance process was analyzed. Problems were derived and a smart device-based automation model was established. In order to establish a smart device-based automation model, ① general flow of facility management process was analyzed and related articles were reviewed, ② current maintenance process was optimized, ③ functional block diagram of BIM Data, COBie Data, IoT, and AR-based automated maintenance management model was created, ④ a smart device-based automated maintenance management model was constructed, ⑤ finally, the above system was verified by testing the aforementioned model in the field site, evaluating the time required for the maintenance process and reviewing maintenance history data against the current one.

기후변화 가속화와 국민의 높아진 서비스 요구 수준에 따라 농업용수의 관리방식을 현장인력의 경험적 물관리 방식에서 계측정보 기반의 과락적 물관리 방식으로 전환의 필요성이 대두되어, 2001년부터 농업기반시설 내 무인계측, 원격제어 기능이 탑재된 물관리자동화 시스템을 보급하는 농업용수관리자동화사업을 시행하였다. 농업용수관리자동화사업은 사업시행 초기 연구 결과, 농업기반시설 무인계측 및 원격제어 시스템 보급으로 인력에 의한 관행적 물관리 대비 수리시설의 관리 효율성이 크게 향상되어 유지관리 인력의 절감 및 용수수급의 적정성이 개선될 것으로 분석되었다. 하지만 영농환경의 변화에 따라, 당초 분석결과와 달리 자동화사업 추진과 한국농어촌공사의 유지관리 인력 규모 간 뚜렷한 상관성이 보이지 않는다는 정책기관의 지적이 발생하고 있다. 현재 4차산업기술이 산업 전 분야에 걸쳐 일어나고 있으며 농업분야에도 ICT, LOT, 빅데이터 기술이 도입되어 새로운 가치를 창출하고 있다. 농업용수관리 분야에 있어서는 데이터를 활요한 수요자 중심의 지능형 물관리 사업이 추진되고 있으며, 일정규모 이상 저수지 및 양수장 농업용수 공급량 측정 계측기의 설치가 추진중에 있다. 그러나 현재까지 이러한 설치된 계측장치들의 활용방안에 대해서는 뚜렷한 결과가 도축된 바 없으며, 현재 많은 예산과 인력이 투입되어 설치·운영되고 있는 계측장치들의 활용 방안에 대해서 연구가 필요한 실정이다. 2018년 2,228개 농업기반시설물에 자동화시스템을 설치 완료 하였으나, 각종 장비의 비표준화, 효과대비 고비용, 잦은 통신두절 등의 기술적 문제로 인해 현업부서의 수자원관리 업무에서 자동화시스템의 활용성이 저조한 것으로 관측됐다. 본연구에서는 국내 수자원 계측제어 기술 동향 및 운영환경 조사 결과를 기초로, 기술적 측면의 농업용수관리자동화사업의 개선사항과 4차 산업기술의 농업용수관리자동화사업의 적용방안을 제시 하여 농업용수관리자동화사업 중장기 계획 개정등 향후 정챡수립시 참고 자료로의 활용과 농업용수 효율적 활용과 관리를 위한 TM/TC 미래추진 방안을 제시로 정확하고 신뢰도 높은 농업용수 관리 체계를 구축 하고자 한다.

최근 지구 온난화 및 기후변화로 인하여 국지적 집중호우에 의한 농지 침수 및 유실 피해가 점차 증가 추세에 있으며 가뭄에 의한 물 부족 현상도 심화되고 있다. 이와 같은 홍수 및 가뭄 피해에 대비하기 위하여 농업용 저수지와 수문 그리고 농수로와 같은 농업수리시설물이 신축 운영되고 있으나 이들 시설물은 비교적 규모가 작은 대신에 그 수가 매우 많고 또한 지역적으로 널리 산재해 있기 때문에 관리자가 이들을 효율적으로 운영하고 관리하는데 한계가 있다는 특징이 있다. 더욱이 이들 시설물은 물과 항상 접하는 철근 콘크리트 구조물로 이루어져 있어서 시간이 경과함에 따라 균열발생과 철근부식과 같은 노후화 현상이 뚜렷하게 진전되어 정기적 안전점검이 필요한 실정이다. 이에 따라 농업수리시설을 보다 체계적으로 관리하고 농업용수를 보다 효율적으로 확보 운영하기 위하여 물관리 자동화 사업이 추진되어 많은 개선이 이루어졌으나 아직까지 현장업무가 관리자의 수작업에 의존하고 있으며 농촌 용수의 정확한 정보가 제때에 제공되지 못하는 등 농업수리시설에 대한 다양한 요구를 충족시키지 못하고 있다. 따라서, 농촌수자원의 효율적 관리를 위하여 농업수리시설 가운데 하나인 농수로의 수위 및 유량 정보를 자동으로 측정하며 농업수리시설물의 상태 정보를 입력하고 관리할 수 있는 모바일 App을 개발하였다. 안드로이드 OS 기반의 스마트폰을 활용하였으며 여기에는 시설물 고유정보가 포함된 QR코드 및 Active 태그를 통하여 시설물의 상태정보를 원격에 있는 서버 컴퓨터로 전송할 수 있는 원거리 무선통신 모듈이 구비되어 있다. 특히, 농업수리시설물 관리 어플리케이션은 현장관리자가 기존에 수기방식으로 시설물을 관리해 오던 것을 휴대단말 상에서 보다 효율적으로 관리를 함으로써 시설물 유지관리 업무의 효율성을 향상시키는 특징이 있다.

The current land characteristics survey to calculate an individual declared land value requires significant manpower, time, and cost. Accordingly, a revised method is required to reduce an economic cost and efficiently extract the information on land characteristics. This study proposed a utilization of spatial information as a means to rapidly and efficiently examine a survey on land characteristics and the method to obtain land characteristics that cannot be obtained in the KLIS (Korea Land Information System) among the land characteristics, which is a basic material in calculating an individual declared land value, via GIS spatial analysis. The proposed methods will not only reduce a significant time and cost as well as a demand necessary in a land characteristics survey but also provide an improvement direction to a current survey method for land characteristics.

Recently, design automation of installation drawings and design elements has been required in the elevator industry. This is recognized as an important role in securing adaptability on site, reducing design errors, and enhancing export competitiveness. However, in case of a small company doesn't have enough resources to develop the program, and it is difficult to develop a design automation program. Therefore, it is necessary to have an automatic drawing generation program that enables small companies to easily invest and use, while allowing users to concentrate on productive tasks. In this paper, we propose an automatic drawing generation program using parametric coding technique. This program is linked with the web service and automatically creates the drawing when the user enters the site information on the web. This is useful for elevator installation and maintenance due to reduced drawing time for elevator drawings.

The public survey performance review conducted by the Spatial Information Quality Management Institute is conducted at the screening rate in accordance with the regulations, and the examiner directly judges the overall trend of the submitted performance based on the extracted sample. However, the evaluation of the Ministry of Land, Infrastructure and Transport, the evaluation trustee shall be specified by random extraction (Random Collection) is specified by the sample. In this study, it analyzed the details of the actual site and analyzed through securing actual performance review data. In addition, we analyzed considerations according to various field conditions and studied ways to apply the public survey performance review sampling algorithm. Therefore, detailed sampling criteria analysis by performance reviewers is necessary. A relative comparison was made feasible by comparing the data for which the real performance evaluation was performed with the outcomes of the Python automation program. This automation program is expected to be employed as a foundation program for the automated application of public survey performance evaluation sampling in the future.

This study was carried out to establish the database system by using the safety inspection and in-depth inspection results for infrastructures such as bridges, tunnels, dams, and water supplies. A classification system of each facility was proposed by standardizing items for inspection & diagnosis in order to automatize work process. Also, it justifies data structure based on database from pre-investigation to field survey, evaluation of facilities, and report making. In addition to this, it suggests improvement plans of relative regulations and guidelines such as Facility Management System(FMS), operational regulation, and inspection detailed guideline to make inspection result database of infrastructures which can be used effectively.

The construction industry has the highest death rate related to safety accidents of any industry. Furthermore, in contrast to other industries, where the death rate related to safety accidents has been steadily declining, both the death toll and the number of accidents in the construction industry have been on the rise. Construction accidents occur when various risks increase in an intertwined way to reach a tipping point; a moment when such factors cannot be tolerated any longer Conventional safety management methods have restrictions in terms of their ability to fully prevent all types of safety accidents. This research considers ways in which USN technology can be applied to safety management on a construction site, and derives a method of applying USN technology for safety management monitoring. The tasks related to safety management on construction sites, as well as the occurrence of accidents, are first analyzed. By analyzing the characteristics of construction accidents, the factors that must be a priority and the factors that can be a lower priority are derived. Finally, the configuration of a monitoring system for safety management on a construction site to which USN technology is applied is presented. It is expected that safety accidents can be prevented from occurring on construction sites by applying this cutting-edge USN technology.
