The purpose of this study is to analyze the effects of smart construction equipment applied at the construction site of the first smart city in the Korea and derive an application strategy for the utilization of smart construction equipment. To achieve this, aythors examined the practical effects and issues of safety systems and construction systems utilizing machine guidance (MG) technology, which is a representative smart construction equipment used in civil engineering construction sites. Both the MG safety system and MG construction system were found to be sufficiently effective in improving construction productivity. However, there are challenges that need to be addressed, such as the approval process for work results using MG systems, system changes due to frequent replacement of on-site equipment, and usability improvements for elderly on-site workers. The study presented some solutions that have been implemented on-site to address these issues. The utilization effects and issues presented in the study were analyzed through direct feedback from workers and managers who have utilized the MG technology on-site for a considerable period of time. These results can be used as preliminary data for the similar construction projects, considering the limited availability of empirical analysis data for equipment automation.

The purpose of this study is to confirm the degree of improvement in performance confidence and executive ability after conducting field adaptation education to dental hygiene students who start their first field practice. Thirty dental hygiene students were evaluated with performance confidence, indirect and direct evaluation of practical skill before and after the field adaptation education was conducted for 15 hours. Also field practice satisfaction was investigated after field practice. A paired t-test was conducted to compare performance confidence, indirect executive ability, and direct practical ability before and after education. Pearson's correlation was performed on the correlation between field adaptation education and field practice satisfaction. Linear regression analysis was performed to identify the influencing factors of field practice satisfaction. As a results, performance confidence, indirect and direct practical skills of after field adaptation program were increased than before that(p<0.05). The correlation between field adaptation education and field practice satisfaction showed that "education satisfaction" among the field adaptation education sub-regions correlated with "education content" and "support of field practice" among the field practice satisfaction sub-regions(p<0.05). Therefore, it is necessary to develop and management various adaptation education in the future as it increases the adaptability of the first field practice and increases the satisfaction of field practice.

This study presented the operation method through of productivity on eight analysis work items (TBM boring, cutter check and exchange, TBM maintenance, succeeding facilities, reinforcement in tunnel, operation alternation, a tram car) which have developed equipment at WRITH with TBM a waterway tunnel works. It was inquired lose time with analyzed result by work items and removed lose time. It was analyzed TBM boring length, TBM boring length percentage and TBM boring length time. This study analyzed TBM operation utility factor of a foreign work with TBM operation boring length percentage, a monthly average boring length, pure boring length percentage etc. and assumed a monthly average boring length and a monthly average boring length of rise forecast. Based on analyzed Data, TBM boring has been forecasted propriety pure boring length at compressive strength $675{\sim}1662kgf/cm^2$.

In case of reducing working time, it is difficult that the construction industry is analyzed far-reaching effects caused by a reduction of working time, by approaching with just the total amount of work. Because it has the properties such as the singularity, the outdoor using, a sense of the season unlike other industries. In order to analyze the effect of a reduction of working time on the construction industry, the example of a reduction of working time in domestic other industries related with it was analyzed intensively first. And an example in Japan, which is similar to our existing related laws and industrial structure among foreign construction industries was analyzed, and a relation with the domestic construction industries and an issue were drown a conclusion. This was applied to a field worker and a related main group participating in a real production. And it showed the prediction model for a working pattern and a dealing plan to prepare in a construction site by predicting a working pattern in the management side of a construction site annually.

The purpose of the current study was to research scientific basis and necessity of supplementary materials for field lesson out of golf swing teaching methods. As the subject of study, skillful tour pro golfers were chosen to reinterpret field lesson results for driver swing from the viewpoint of kinematics. In addition, through precise analysis, this study developed a case to verify the validity and error of field lesson. As a result, field lesson showed a slight difference among qualitative evaluation of kinematical analysis of techniques, subjects of study, and items. Accordingly, there was a little difference between two methods in view of evaluation of errors that 5 subjects of the study have shown. However, there was a significant difference in compensation to prevent causes of error and errors. Based on instructor's experience most errors could be evaluated. Therefore, feedback for error correction based on instructor's experience showed a significant difference from qualitative evaluation of kinematical analysis of techniques. In conclusion, the following are required for correct golf swing lesson; instant feedback through field lesson and qualitative evaluation of kinematical analysis of techniques to determine fundamental causes correctly.

This study is a research for analysis the states of flame resistant treatment and its system which important in fire prevention by ignition delay of early stage of fire. Some problems arose in the flame resistant treatment site were analysed through the meeting with fire officer and businessman related with flame resistant treatment, and visiting the flame resistant treatment places. From the meeting, visiting and reviewing the code system we find the following problems. First one is a problem of excessive competition with many company in small market of flame resistant treatment and to reduce the cost, the businessman who have no professional technic do not work along the specification. Second one is the inspection system which do not inspect on site but inspect by sampling the flame resistant treated materials submitted by businessman. And there are some problems arose about the reliability and consistency of flame resistant performance of the sample and the treated site. To solve the above problems, we suggest some countermeasure.

Most accidents at construction sites are occurring in vulnerable groups such as new workers, foreign workers, and elderly workers. These vulnerable workers often lead to accidents due to the lack of awareness of risks. Therefore, in order to reduce accidents, it is necessary to pay attention to and manage vulnerable workers. This study attempted to identify the level of safety awareness and safety management priorities for vulnerable workers through IPA analysis. New workers should be able to adapt to the field as soon as possible, and foreign workers were found to need frequent check-ups due to language communication problems. In the case of older workers, it was analyzed that it was necessary to check their health and to check whether they were performing other tasks than the prescribed ones.
