As industrial safety increases, various industrial accident prevention technologies using smart factory technology are being studied. However, small and medium enterprises (SMEs), which account for the majority of industrial accidents, are having difficulties in preventing industrial accidents by applying these smart factory technologies due to practical problems. In this study, customized monitoring and warning systems for each type of industrial accident were developed and applied to the actual field. Through this, we demonstrated industrial accident prevention technology through appropriate smart factory technology used by SMEs. A customized monitoring system using vision, current, temperature, and gas sensors was established for the four major disaster types: worker body access, short circuit and overcurrent, fire and burns due to high temperature, and emission of hazardous gas. In addition, a notification method suitable for each work environment was applied so that the monitored risk factors could be recognized quickly, and real-time data transmission and display enabled workers and managers to understand the disaster risk effectively. Through the application and demonstration of these appropriate smart factory technologies, the spread of these industrial safety technologies is to be discussed.

This study implemented intelligent compaction technology at the construction site of the AY Highway in Gyeonggi Province, with a focus on obtaining the representative intelligent compaction value, CMV. The target CMV for quality control was established through trial construction, and the validation of the compaction quality control process based on intelligent compaction was conducted. The optimal approach for determining the target CMV was confirmed to be through linear regression of the average CMV measured within a 5-m radius from the plate load testing location. Upon assessing compaction quality against the target CMV, it was observed that the quality criteria outlined in the domestic intelligent compaction standard were met. However, the criteria outlined in Austria and the United States were not satisfied. Notably, indicators related to the variability of compaction quality did not meet the specified criteria, suggesting a stringent standard compared to the observed variability of CMV, ranging from 17% to 55%. Consequently, it is recommended to conduct additional field tests to further validate the compaction quality control process based on intelligent compaction. This will aid in confirming and enhancing the appropriateness of the regulations stipulated in each standard.

Existing verification research for how effectively the educational training of new fire officers has been applied to actual fieldwork is extremely insignificant. This is because only a few studies have empirically verified job implementation according to job satisfaction, which is believed to have a great influence on various aspects such as learner traits, educational programs, and learning outcomes. Moreover, it is necessary to conduct an empirical investigation regarding the effects of learner traits, educational programs, and learning outcomes on disaster scenes and the job implementation of fire administration on new fire officers. This study aims to provide an empirical analysis of the effects of educational training of new fire officers on job implementation. It has been identified that learner traits and learning outcomes have an effect on job satisfaction. Accordingly, job satisfaction, educational programs, learning outcomes, and learner traits have a significant effect (P < 0.05) on job implementation.

The purpose of this study is to verify the performance of a static mixer for mixing of biogas and town gas by numerical analysis and demonstration test. The reason for designing a static mixer is that there is a need to mix town gas with biogas when there is less production of biogas in biogas sites. Non-uniformity in the outlet section was calculated for investigating the performance of a static mixer. Non-uniformity was based on the mole fraction of methane in a mixture of biogas and town gas. Low non-uniformity means that biogas and town gas are mixed well through this static mixer. Also, pressure drop at the outlet section of a static mixer was calculated. The pressure drop is less than 0.2% in this static mixer. This static mixer is suitable for applying to a 5MW bio-gas turbine through the demonstration test in the field.

With the aim of preventing safety accidents at construction sites, the company aims to create safe behaviors intended through variables called smart safety and health activities to help reduce industrial accidents. Purpose: It analyzes how smart safety and health activities affect accidents caused by unsafe behavior and changes in worker behavior, which is the root cause, and verifies the hypothesis that it helps prevent safety accidents and protect workers' lives. Method: Smart safety and health activities were selected as independent variables (X), and intended safety and anxiety, which are workers' behavioral intentions, were set as dependent variables (Y), attitude and subjective norms, and planned behavioral control as parameters (M). Exploratory factor analysis, discriminant validity analysis, and intensive validity analysis of safety and health activities were used to analyze the scale's reliability and validity. To verify the hypothesis of behavior change, the study was verified through Bayesian model analysis and MC simulation's probability density distribution. Result: It was found that workers who experienced smart safety and health activities at construction sites had the highest analysis of reducing unstable behavior and performing intended safety behavior. The research hypothesis that this will affect changes in worker behavior has been proven, the correlation between variables has been verified in the structural equation and path analysis of the research analysis, and it has been confirmed that smart safety and health activities can control and reduce worker instability. Conclusion: Smart safety and health activities are a very important item to prevent accidents and change workers' behavior at construction sites.

As current business environment is experiencing radical changes, interest in brands has increased theoretically and practically. The growing interest in brands creates the need for brand equity measurement and management models that help companies manage and fortify brands continuously. Given the situation, this study analyzes effects of brand equity on purchasing behavior of consumers. Outcomes of this study can be employed as integrated brand management system in order to satisfy corporate needs for systematic brand management. This model has been developed in an effort to transcend varied limitations of other previous studies and existing models. Consequently, the practical value of this model is highly expected. Beyond the mere concept of brand for establishing differentiated position against competitors, contents of the study cover extended forms of brand equity and brand performance. This model has been tested through practical applications of fifteen brands from three product categories. Despite several disparities among the categories, the study has revealed that the overall market performance of the brands is correlated with the brand power and other factors in the model. As the importance of brands is growing, brand management is an essential step for power branding. And brand management requires extensive brand diagnosis. The practical results of this study indicate that companies should put an emphasis on brand-oriented management as core strategy of their business.
