  • The spatial limitations of urban environments in general lead to invention and design of a wide range of underground transportation systems such as subways, underground roads and paths, etc. Among them, the application of subway systems in metropolitan cities is most commonly observed to ease those confronted difficulties on this purpose. It in turn leaves passengers and workers to be exposed to indoor air potentially polluted by various sources existing in this underground environment. Specifically when considering the IAQ in a subway station, there exist many IAQ-related parameters to be counted either as individual or as integrated exposures. In this study, a model system has been developed to manage the general IAQ in a subway station. Field survey and $CO_2$ measurements were initially conducted to analyze and understand the relationship between the indoor and outdoor air quality while considering the internal pollution sources such as passengers, subway trains, etc. The measurement data were then employed for the model development with other static information. For the model development, the algorithm of simple continuity was built and applied to model the subway IAQ concerned. In this paper, the recent updated draft version of model developed will be reported and demonstrated.

  • Purpose: The purpose of this study was to investigate factors influencing severity of occupational fall injury. Methods: A self-reported questionnaire was completed by 105 patients sustaining occupational fall injury between July 2010 and January 2013. The study instruments were developed by the National Traumatic Occupational Fatalities and National Electronic Injury Surveillance System. The questionnaire consisted of general characteristics of the subjects (30 items), workplace characteristics (12 items) and disaster characteristic (13 items). Results: Demographic factors, except age, did not affect the severity of injury. Injured patients aged 50-59 years tended to have more severe injuries than those aged 39 years. Type of transport vehicles, conditions, and the circumstances of the fall influenced injury severity. Patients transported by 119 ambulance suffered more severe fall injuries than those who were not. Electrical workers did not receive safety education wihin a year. Critical height in severe injuries was > 6 meters. Conclusion: Occupational fall injuries were influenced by patient age, types of transport vehicles, fall height, size of workplace, and safety education experience.

  • Purpose: The purpose of this study is to look at the current status and cases of ESG at home and abroad, and through this, seek ways to activate the ESG strategy of domestic SMEs and suggest a direction. Research design, data and methodology: This study examines the current status of ESG management at home and abroad and examples of companies through related literature on ESG management and performance. Through this, the strategic direction of ESG management of domestic SMEs was presented. Results: Compared to the government and major corporations, SMEs can be said to lack ESG management activities. ESG activities include environmental activities such as carbon neutrality, waste management, eco-friendly supply chain management, establishment of safety and health processes to improve workers' environment, expansion of governance to guarantee autonomy and profitability such as fair trade, protection of social and shareholder rights such as anti-corruption, etc. should be based on Therefore, there are difficulties in ESG activities of SMEs that lack funds and manpower.

  • Objectives: In order to provide basic data for future researchers, this study aims to explore future tasks after reviewing the changes in port safety management due to the enforcement of the Special Act on Port Safety. Methods: The provisions of the Special Act on Port Safety were analyzed and the latest literature related to port safety management was reviewed. Results: There are two major changes that have stemmed from the Special Act on Port Safety: 1. The scope of application for port participants has been expanded, safety education has been made compulsory, and safety management plans have been established and implemented for each business site. 2. The government is operating a port safety consultative body for each port and has hired one port safety inspector for each of the eleven local maritime and fisheries offices across the country. Future tasks include elaboration of port safety accident statistics, strengthening shipping companies' responsibility for stevedore safety, the unification of contracts, and government interest and support for port safety facilities. Conclusions: The primary feature of the Special Act on Port Safety is the emphasis on autonomous safety management by participants in port transportation. In addition, the enactment of the special law has allowed the Ministry of Maritime Affairs and Fisheries to actively intervene in port loading and unloading safety.

  • The COVID-19 pandemic has significantly impacted how people work, resulting in a massive shift towards working from home or remotely. Work from home has played a critical role in reducing the transmission of COVID-19 by limiting in-person interactions and reducing the density of people in office buildings. It also enabled businesses and organizations to continue operating while keeping their employees safe and healthy. The COVID-19 pandemic accelerated the adoption of work from home in business and organizational sectors worldwide, and it is likely to continue as a preferred mode of work even after the pandemic is over. This shift towards working from home has not only impacted the way people work but also has significant implications for urban development, transportation, and the environment. This study intends to develop measures for addressing potential physical and mental health issues among remotely working employees. Additionally, it identifies the major influencing factors of home workers' health hazards and proposes improvement measures that can be applied to working from home, along with existing laws and prevention methods.

  • Recently, the development of computer vision with deep learning has made object detection using images applicable to diverse fields, such as medical care, manufacturing, and transportation. The manufacturing industry is saving time and money by applying computer vision technology to detect defects or issues that may occur during the manufacturing and inspection process. Annotations of collected images and their location information are required for computer vision technology. However, manually labeling large amounts of images is time-consuming, expensive, and can vary among workers, which may affect annotation quality and cause inaccurate performance. This paper proposes a process that can automatically collect annotations and location information for images using eXplainable AI, without manual annotation. If applied to the manufacturing industry, this process is thought to save the time and cost required for image annotation collection and collect relatively high-quality annotation information.
