This study investigated the distribution behaviors of PM2.5 and PM10 at two air quality monitoring sites, Go-eup (GO) and Backseokeup (BS), located in Yangju City, South Korea. The amounts of emissions sources of pollutants were analyzed based on the Clean Air Policy Support System (CAPSS), and the contribution rates of neighboring cities were enumerated in Yangju. Yangju has a geological basin structure, and it is a city with mixed urban and rural characteristics. The emission concentration of particulate matter was affected by geological and seasonal factors for all sites observed in this study. Therefore, these factors should be considered when establishing policies related to particulate matter. Because the official GO and BS station sites in Yangju are both situated in the southern part of the city, the representativeness of both stations was checked using correlation analysis for the measurement of PM2.5 and PM10 by considering two more sites-those of Bongyang-dong (BY) and the Gumjun (GJ) industrial complex. The data included discharge amounts for business types 4 and 5, which were not sufficiently considered in the CAPSS estimates. Because the 4 and 5 types of businesses represent over 92.6% of businesses in this city, they are workplaces in Yangju that have a significant effect on the total air pollutant emission. These types of businesses should be re-inspected as the main discharge sources in industry, and basic data accumulation should be carried out. Moreover, to manage the emission of particulate matter, attainable countermeasures for the main sources of these emissions should be prepared in a prioritized fashion; such countermeasures include prohibition of backyard burning, supervision of charcoal kilns, and management of livestock excretions and fugitive dust in construction sites and on roads. The contribution rates by neighboring cities was enumerated between 6.3% and 10.9% for PM2.5. Cooperation policies are thought to be required with neighboring cites to reduce particulate matter.

Human error, a leading cause of construction accidents, emphasizes the need for minimization to reduce such incidents. However, due to the nature of the construction industry, workers operate within the collective environment of a construction site. Therefore, this study investigates the influence of safety awareness levels within construction sites on the human errors committed by construction workers, from an organizational perspective. The analysis revealed that human errors directly impact construction accidents and that safety awareness levels within construction sites influence the human errors committed by construction workers. Specifically, a strong correlation was observed between slip errors(unintentional actions or oversights) and safety awareness levels in nearly all domains of construction site safety. This study highlights that by elevating safety awareness levels within construction sites, the likelihood of construction worker slips - and by extension, construction accidents - can be significantly reduced.

The purpose of this study was to identify the competing values leadership of restaurant general managers and to investigate the impact of their competing values leadership on employee job satisfaction and turnover intention. A sample of full-time restaurant employees (n=360, 36% response) completed an e-mail survey. The results showed that among the eight sub-dimensions of competing values leadership roles, the monitor (4.04), producer (4.01), and director (3.99) roles were perceived as the most frequently used leadership styles of managers compared to broker (3.78), innovator (3.83), and mentor (3.91) roles (p <0.001). Additional T-test results suggested that an employees' gender had an influence on how he/she perceived the leadership style of their manager. Male employees were more likely to perceive that the director and mentor roles (4.19) were performed very well by their managers, while female employees perceived that their managers concentrated more on monitor (3.98) and producer (3.96) roles rather than on broker (3.73) and innovator (3.79) roles (p<0.05). It was found that manager competing values leadership had a significant correlation with employee job satisfaction, and the mentor, coordinator, and innovator manager roles explained the relationship with 42.1% based on multiple regression analysis (p<0.001). In further findings, the manager competing values leadership roles had an effect on employee turnover intention. The results of the data were as follows: mentor and facilitator roles promoted a decrease in employee turnover intention and the director role caused employee turnover intention to increase. Ultimately, this study will be useful for restaurant managers to guide the application of appropriate competing values leadership roles in order to strengthen employee job satisfaction and to reduce turnover intention.

In this study, the effect of sea surface temperature (SST) on the distribution of vertical wind speed in the atmospheric boundary layer of coastal areas was analyzed. In general, coastal areas are known to be more susceptible to various meteorological factors than inland areas due to interannual changes in sea surface temperature. Therefore, the purpose of this study is to analyze the relationship between sea surface temperature (ERA5) and wind resource data based on the meteorological mast of Høvsøre, the test bed area of the onshore wind farm in the coastal area of Denmark. In addition, the possibility of coastal disasters caused by abnormal vertical wind shear due to changes in sea surface temperature was also analyzed. According to the analysis of the correlation between the wind resource data at met mast and the sea surface temperature by ERA5, the wind speed from the sea and the vertical wind shear are stronger than from the inland, and are vulnerable to seasonal sea surface temperature fluctuations. In particular, the abnormal vertical wind shear, in which only the lower wind speed was strengthened and appeared in the form of a nose, mainly appeared in winter when the atmosphere was near-neutral or stable, and all occurred when the wind blows from the sea. This phenomenon usually occurred when there was a sudden change in sea surface temperature within a short period of time.

Despite the development of the aviation industry, aircraft accidents due to pilots' human errors continue to occur. The cause of aircraft accidents due to human errors is that they cannot remove hazard factors that hinder flight safety in advance, leading to accidents. This study examined how job stress, fatigue, and anxiety, which psychologically and physically affect flight safety among various hazard factors, affect pilots' safety behavior for flight crew and pilots of general aviation working in domestic airlines. In addition, an empirical analysis was conducted to confirm the mediating effect of safety culture between job stress and safety behavior. According to the results of the study, job stress not only directly affects the safety behavior of pilots, but also affects the safety culture of airlines such as safety atmosphere and reporting culture. The purpose of this study is to improve the performance of the safety management system through the correlation between the pilot's job stress and safety culture and safety behavior.

With the increasing global interest in carbon neutrality, the automotive industry is also transitioning to the production of eco-friendly cars, specifically electric vehicles. In order to achieve comparable driving distances to internal combustion engine vehicles, the application of high-capacity battery packs has led to an increase in vehicle weight. To achieve light-weighting and durability requirements of automotive components simultaneously, there is a demand for research on the application of Ultra-High Strength Steel (UHSS). However, when manufacturing chassis components using UHSS, there are challenges related to fracture defects due to lower elongation compared to regular steel sheets, as well as spring-back issues caused by high tensile strength. In this study, a simulated specimen that is not affected by the property changes of four materials was designed to improve formability of the rear cross member, which is the most challenging automotive chassis component. The influence and correlation of material-specific variables were analyzed through finite element analysis (FEA) for each material with tensile strength of 440, 590, 780, and 980 MPa grades, resulting in the development of a predictive equation. To validate the equation, the simulated specimens of 980 MPa grade were produced from the test molds. Then the reliability of the FEA and predictive equation was verified with measured specimen data using a 3D scanner. The results of this study can be proposed to improve the formability of UHSS chassis components in future researches.
