Railroad construction requires a lot of budget, manpower, and equipment, and as a result, many accidents occur. Although efforts are being made at the national level to reduce the accidents at railway construction sites, the occupational accident rate is not showing a downward trend. Various efforts are needed to reduce accidents, the application of smart construction safety technology will be effective. However, if smart construction safety technology is introduced indiscriminately without analysis, duplicate investment may occur, which may lead to a waste of budget for railway construction. In this regard, this study analyzes accident cases at railroad construction sites through a survey of stakeholders and proposes smart construction safety technologies to be effective for those accident types.

Currently, the advanced construction technology endorsement system is being operated to promote the development of domestic construction technology. We tried to examine the implicit meanings inherent in advanced construction technologies by analyzing the relationship between emerging vocabularies with high importance in relation to the advanced construction technologies endorsed through this system. For this purpose, 918 cases of advanced construction technology information were collected. Based on the endorsed year and summary of the advanced construction technologies, the importance of the emerging vocabularies was measured for each advanced construction technology. And, based on the LDA model, the degree of influence between related vocabularies was evaluated for each of the four topic areas. Topics according to the technical application fields were analyzed. From 1990 to 2021, the trend of changes in highly influential vocabularies by each topic was inferred. In the future, changes in the degree of influence of the topics of environment, machinery, facilities, and maintenance and reinforcement of structures and related technology fields were predicted.

Drone is a suitable equipment for capturing images of cracks at construction sites based on its efficient mobility and high-resolution image acquisition capabilities. In this study, drone was used to acquire indoor construction sites framework images and deep learning technology was applied to detect cracks and measure width, and size. Finally, the usability of the process was verified based on the indoor crack monitoring system.

최근 스마트폰은 단순히 일상생활 뿐 만이 아니라 다양한 산업에서 활용되고 있다. 이와 같은 움직임은 건설 산업에서도 발견되고 있다. 많은 건설 기업에서 이미 스마트폰 도입이 이루어지고 있으며, 이를 통해 건설 산업에서 요구되고 있는 비용 절감 및 생산성 향상을 이루고자 한다. 건설 산업에서는 건설 현장 관리를 위하여 이미 PDA를 비롯한 여러 기술의 도입을 통해 이와 같은 요구를 해결하고자 하였다. 그러나 PDA의 경우 PDA가 가진 여러 한계점으로 인하여 도입 효과가 다소 미미하였다. 반면에 스마트폰은 별도의 장비 도입이 아닌 단순히 어플리케이션 개발을 통해 진행될 수 있다는 장점이 있다. 이에 본 연구에서는 스마트폰을 기반으로 하는 건설 현장 관리 시스템을 개발하였다. 개발된 시스템은 건설 기업의 현장 인터뷰 및 설문을 통한 요구사항 분석 결과를 기반으로 개발되었으며, 실제 현장에 적용하여 테스트함으로써 개발 시스템의 효과 및 보완 사항을 분석하였다.

Since the Act on Punishment of Serious Accident has been implemented, the role of construction companies in safety and health and the responsibility of CEO are strengthened. However, serious accidents still occur. Due to population decline and young people's reluctance into the construction industry, the ratio of elderly workers and foreign workers is increasing at construction sites. In this study, a survey was conducted to identify differences in the perception of importance of smart safety technology among vulnerable groups such as foreign workers, elderly workers, and workers with health conditions. Vulnerable workers recognize the importance of smart technology in the fields of foreign language support, risk warning, and body wear monitoring, and the conclusion was drawn that smart technology should be expanded for vulnerable groups in the future.

To prevent fall from height, interest in the development and introduction of smart harness is increasing as policies and laws such as mandatory use of smart safety equipment at construction sites. However, despite the potential of smart harness, construction safety cannot be contributed unless adopted or used by users. The objective of this research is to examine the perception between safety managers and workers on smart harness, user perception according to user's experience and differences through semi-structured in-depth interviews. As a result of the interview and comparative analysis, both safety managers and workers perceived smart harness as uncomfortable, and workers with experience in using smart harness perceived that simple functions that inform risks are useful for securing safety. This research results show different user's perception of smart harness can be confirmed how much factors affect the use of smart harness, which can provide implication into establishing measures to strengthen the use of smart harness in the future.

The Construction Technology Information System collects, processes, and provides the public with free of charge 16 types of construction technology-related texts or index information, such as construction standards, construction practices, and construction reports, required at construction sites to enhance domestic construction technology. This study judged that user satisfaction could be increased if the budget was allocated first to the most effective construction technology information DB establishment. For each type of construction technology information, the level of satisfaction felt by the population for the quantity provided and the value of use according to the acquisition and utilization of information were investigated. Reliability between independent variables and dependent variables through a multiple regression analysis process to identify how the demographic characteristics of the population affect user satisfaction and the factors that affect the use value of information for each type of construction technology information. and the correlation was analyzed. The correlation between the demographic characteristics of respondents and users' satisfaction with the provided quantity was generally low, but construction experience, age, etc. were found to have an effect on satisfaction with the provided quantity. In particular, among the demographic measurement items of respondents, the more construction experience they had, the higher their satisfaction level with the quantity provided of low-level technical standards, and it was analyzed that older age had an impact on satisfaction with the quantity provided for small and medium-sized business support information.
