In the construction industry, IT based information system has been diversely applied to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced to gather information in construction site, the effect of the IT device is limited, because of bringing about additional works of engineer. In this paper, we proposed a defect management system which is based on handwritten document digitalization framework for introducing applicability of new IT device, digital pen. By the proposed system, we can effectively gather and input defect information to defect management system by using digital pen and paper like conventional way. Applying the data gathering device, digital pen to defect management, it is able to increase productivity by improving work process, building up and utilizing defect information database of good quality.

The digital motor protection, measuring and control equipment, as called "The digital motor control equipment", for applying to single/three phase motors designed an integrated one unit and manufactured a compact size which will be installed on the motor control center. It performs serveral protection functions and motor starting function, and measures and indicates a serveral measurement. This paper proposes the design concept and functionality of new digital motor control equipment to improve control performance and integrate several equipments for the control and protection of the motor.

This report describes the development of a program that can be linked to an alignment and extracts related information using a prefab structured digital engineering model. The subject bridge was set as a straight alignment, the Superstructure type as Precast girder and the Substructure type as Precast pier and Cast-in-situ Abutment. We identified the variables required to create a digital engineering model and reviewed them to create the digital engineering model by entering them as numerical values in the program. In addition, it is configured so that the variables linked to the alignment can be entered numerically. The quantity takeoff can be calculated when the design is complete. The purpose of the program development presented in this report is to enable the designers to select the optimal alternative by designing a bridge that best fits their current situation, extracting the relevant information and then by providing it to the manufacturer and construction company.

Currently, in spite of continual efforts, the information utility of the construction industry does not communicate well with other industries. This problem arose from mistaken and misguided efforts on the parts of the construction industry because it left out of consideration construction characteristics which are at the center of construction, and this information system was directly introduced and operated from outside the industry. There were also other mistakes that the existing information systems disregarded in trying to fix these problems. Therefore, this study describes a new process, which proposes to build and utilize a Bridge Management System using the mobile internet concept, to solve the problems of the existing construction information management system.

This study aimed to understand whether or not academic outcomes in digital studies shown in detailed field of costume were generated appropriately according to the development of digital technology by analyzing contents of studies in the digital-related studies, which were conducted with a background of the digital age. First, as a result of frequency of digital-related theses by the age of 'Internet Age(1994-2000)', 'Digital Age(2000-2009)', and 'Smart Life Age(After 2010)', which were classified according to the digital environmental changes, the number of theses increased drastically based on the transition point of each age. Second, representative keywords that appeared in each age included 'digital' and 'Internet' in the Internet Age, and 'digital', 'smart', 'Internet', '3D', and 'wearable' were shown in the 'Digital Age' and 'Smart Life Age'. Third, results of analysis according to the field of costume show that relevant studies were conducted in three fields of marketing/information, clothing construction and fashion design in the Internet Age, whereas the Digital Age produced relevant studies in all fields, and Smart Life Age was characterized by increase in studies in the field of fashion design and clothing construction. Fourth, results of analysis according to the contents of study show that relevant studies in the Internet Age were shown only in two subjects of 'preliminary study and trend of study' and 'studies using technical programs', and 'preliminary study and trend of study' decreased, but relevant studies in other fields of subject increased in the Smart Life Age. As shown above, relevant studies appeared as various subjects in many different detailed fields of costume in costume studies according to the stream of the Smart Life Age, which is growing fast recently, and is considered an inspiring result for development of studies in the field of costume according to the environment of the age.

With the development of digital technology, construction companies at home and abroad are in the process of computerizing work and site information for the purpose of improving work efficiency. To this end, various technologies such as BIM, digital twin, and AI-based safety management have been developed, but the accuracy and completeness of the related technologies are insufficient to be applied to the field. In this paper, the learning data that has undergone a pre-processing process optimized for recognition of construction information based on structural members is trained on an existing artificial intelligence model to improve recognition accuracy and evaluate its effectiveness. The artificial intelligence model optimized for the structural member created through this study will be used as a base technology for the technology that needs to confirm the safety of the structure in the future.

In an era where everything is digitalized using AI(Artificial Intelligence), such as the ChatGPT craze, the evacuation guidance system still uses an analog and fixed method, so there is a limit to quick response in case of fire. In order to overcome this, we introduce a digitally transformed evacuation guidance system using AI and discuss its effectiveness.
