As the construction site becomes larger, more complex and more special, the information of construction is expanded in quantity and specialized in quality. Therefore the computing system is necessary to effectively manage the construction schedule management. At present, main office at construction site bring in the computing system to perform the schedule management, so the data input and access for schedule management is performed by engineer on foot between construction site and main office. Therefore in this paper, we arrange wireless communication system between construction site and main of office and develop application program for data input and access of schedule management immediately using PDA at construction site. Through the our system we can improve the schedule management at construction site, and we can look forward to reduction of manpower, equipments, time, and money in whole construction.

4차 산업혁명에 따라 유역 및 하천관리 사업, 각종 풍수해 예방사업 분야에 다양한 스마트기술이 도입되고 있으나 건설현장 침수 피해 사고는 지속적으로 발생하고 있다. 굴착공사 현장에서 발생할 수 있는 침수피해를 사전에 예측하기 위해서는 공정별로 변화하는 현장상황을 반영하여 다양한 강우 시나리오를 기반으로 침수 예측 모델링이 선행되어야한다. 따라서 본 연구에서는 2차원 동수역학 모형인 HDM-2D 모형을 기반으로 굴착공사 현장 침수피해 예측 모델을 개발하여 굴착공사현장 침수 예·경보 시스템에 탑재하고자 한다. 침수피해 예측 모델은 천수방정식을 Petrov-Galerkin stabilized scheme 으로 이산화하여 해석하는 수평 2차원 동수역학 흐름해석모델로서 수로 및 지표면 등 다양한 지형 상황에서의 물 흐름을 상세하게 해석할 수 있다. 지형자료 생성 이후 경계조건 부여를 통해 수행되며 침수발생지역의 유속, 수심, 수위를 취득할 수 있다. 배수지나 굴착공사 현장에 2차원 흐름해석을 적용하는 경우 지형의 경사나 배치가 공간에 따라 변화하므로 불연속적인 흐름을 유발하여 모의결과의 계산 오차를 검토해야 한다. 2차원 침수피해 예측 모형의 정확성을 확인하기 위해 지면 돌출부가 있는 흐름 문제와 테스트베드 대상지에 침수해석 모형을 적용하였다. 돌출부 흐름 문제의 경우 돌출부를 지나며 발생하는 유속과 수심 모의 결과를 상용모형과 비교검증 하였으며 테스트베드 대상지역에 침수피해예측모형을 적용했을때 지형 경사에 따른 흐름의 변화와 침수양상을 확인할 수 있었다.

Today, scale of a disaster becomes huge, all the available resources should be mobilized to control the disaster situation, and situations of the disaster site is broadcasted by the various media on a real-time basis. Accordingly, The commander of the disaster site should manage the situation taking all the factors into consideration. Despite the importance of the factors affecting the command of disaster site, there are not much research on this topic. This study utilizes METT-TC(Mission, Enemy, Troops, Terrain and weather, Time available, and Civilian considerations) which is applied in a combat situation by the military area and proposes MORT-TEC(Mission, Object, Resources available, Terrain and weather, Time available, Exercise, and Civilian considerations) as factors affecting the effective command of disaster site. These factors are applied to the Sewol Ferry Incidents and policy implications which can help researchers and practitioners in the area are suggested.

This study aims to suggest a new method to escape crisis of manufacturing industry. We focused on the field - oriented management innovation promotion performance divided into qualitative performance and quantitative performance. The site-centered management innovation is an organization that helps managers to quickly solve the problems faced by field management personnel by switching from manager-centered management method to on-site management personnel-oriented management. Find out the waste factors of the work and improve the process and set the process standards according to the customer's needs. Before working on the site, an employee should know exactly the process standard of what I will do, and frequently inspect the raw materials to make sure they meet the specifications. After the self-inspection is carried out, the standard is reviewed. If there is no abnormality, the cross-validation is carried out by the method which is carried over to the next step. The results of this study can be used to enhance the competitiveness of manufacturing companies. New management innovation techniques are required to adapt to the rapidly changing international business environment, and this study has implications for this research.
