Recently, research on digital twins to generate digital information and manage construction in real-time using advanced technology is being conducted actively. However, in the construction industry, it is difficult to optimize and apply digital technology in real-time due to the nature of the construction industry in which information is constantly fluctuating. In addition, inaccurate information on the topography of construction projects is a major challenge for earthmoving processes. In order to ultimately improve the cost-effectiveness of construction projects, both construction quality and productivity should be addressed through efficient construction information management in large-scale earthworks projects. Therefore, in this study, a 3D digital map-based AR site management work support system for higher efficiency and accuracy of site management was proposed by using unmanned aerial vehicles (UAV) in wide earthworks construction sites to generate point cloud data, building a 3D digital map through acquisition and analysis of on-site sensor-based information, and performing the visualization with AR at the site By utilizing the 3D digital map-based AR site management work support system proposed in this study, information is able to be provided quickly to field managers to enable an intuitive understanding of field conditions and immediate work processing, thereby reducing field management sluggishness and limitations of traditional information exchange systems. It is expected to contribute to the improvement of productivity by overcoming factors that decrease productivity in the construction industry and the improvement of work efficiency at construction sites.

Recently, the scale of construction project is getting bigger compared to previous projects. Therefore, the job stress of the field manager responsible for the construction project is getting more and more intense. Therefore, construction companies should establish a job stress management plan for stable human resource management of the field managers. From this perspective, in this study was developed a job stress measurement system in connection with MBTI personality types. The developed system allows the job stress of the field manager to be judged on a scale from 1 to 9 points. Accordingly, it is expected that construction companies will contribute to the effective management of field managers in the future.

Recently Korean enterprises that branch out into China have been continuously increased to achieve diverse objectives such as personnel expenses reduction, market share extension on China and globalization strategy implementation. We have studied about competitiveness reinforcement of enterprises that branch out into China in terms of TPM(Total Production Management). In this paper, we extended the concept of traditional TPM(Total Productive Maintenance) to TPM(Total Production Management) that covers extensively the concept of total management innovation activities. We explored detailed activities of TPM and voluntarily participative field research circle. Also, We suggested some prerequisite conditions for TPM settlement that might be recommended for the foreign companies in China and checked Key Performance Indicator(KPI) that could be useful to confirm how TPM contributed to enterprise competitiveness reinforcement.

The scopes of the supply chain management in construction projects has expanded from the field management focusing on field storage, transportation, and lifting to the whole supply chain from the materials to field. The expansion of the supply chain management can raise the possibilities of leaner production, which enables shortened lead time of the difficult-to-operate materials, and prevents the work interference or delay. However, the expanded management range requires more information and management than an existing management style currently used for factory production of iron frame, curtain wall, PC, etc. In addition, there are limitations that expand the existing management style into the new supply chain management in construction projects and therefore it is required to automate the existing management style in order to extend the management range. The objective of this study is to propose the process and equipment that can manage the supply chain of the materials which range from the factory production to the field storage based on RFID/USN techniques, introducing small-sized transportation equipment(intelligent pallet), the vehicle tool kit(intelligent trailer), and in-and-out management equipment(Gate Sensor) as a prototype to effectively develop the appliances for operating the proposed process, and present the application possibility of the appliances. The full paper will present then the test results that the proposed appliances for the supply chain management automatically transmit and receive the generated information between the appliances or the appliance and sever under various wireless network circumstances such as zigbee, wibro, Wi-Fi, and CDMA.

This study aims to analyze the aquaculture farmers awareness of aquafarm management system influenced by socio-economic, environmental, and other factors using ordered logit model focused on aquafarm resting system. The survey data were obtained from 94 aquaculture farmers in Gyeongsangnamdo and Jeollanamdo province as a cross sectional data in 2015. This paper estimates the impact of socio-economic, environmental, and other characteristics, such as region, working period, productivity, environmental condition of fishing field, expected effectiveness of the system, and subject of responsibility on fishing field management. Based on the result, lastly, it suggests some implications to promote aquaculture farmers perception and participation in aquafarm resting system. The main results are as follows; the aquaculture farmers consciousness of the system is not affected by working period, productivity, and environmental condition of fishing field. But it is influenced by region, expected effectiveness of the system, and subject of responsibility on fishing field management. While it has a positive relationship with expected effectiveness of the system, it has a negative relationship with object who has responsibility on fishing field management.
