Abstract

Purpose: This study aims to understand the types and amounts of greenhouse gases among substances generated when operating facilities at resource recovery facilities in Seoul and analyze their impact on the environment. Research design, data and methodology: As a research method, you can directly visit four resource recovery facilities in Seoul, investigate greenhouse gases generated when operating the facilities, and then understand the distribution of generation through the greenhouse gas calculation formula. In addition, the impact, distribution, etc. that they have regionally can be confirmed by comparing the emission source and the surrounding site boundary line through the environmental impact survey report Results: When operating resource recovery facilities, you can determine whether there is a possibility that they will actually affect the surrounding areas, especially in areas where humans reside, such as private homes and vulnerable facilities, and if so, the results can be determined. The goal of this study is to understand how much the effects of greenhouse gases contribute to climate change and what the effects are on the human body. Conclusions: he results of this study can identify the causes of negative images of the survival of resource recovery facilities and the expansion and establishment of new resource recovery facilities, and suggest eco-friendly measures such as waste export, recycling, and recycling instead of new construction on the impact on climate change.

Abstract

Purpose: The purpose of this study is to present basic data that can be used as a program to improve emotional stability and daily life ability by reducing depression and improving the quality of life of the elderly using day care facilities. Research design, data and methodology: Changes in each stage of the study subjects were observed and interviewed, and pre- and post-tests were conducted on the depression and quality of life of the elderly in the group program. The measurement tool was designed for pre- and post-test using the tools of the Korean Elderly Depression Test (K-GDS) and the elderly's quality of life test. Results: As a result of observing and interviewing participants, and examining attitudes and reactions to each session, the pre-test showed a negative attitude, but then communicated with each other to form a positive relationship. As a result of pre- and post-test on the depression and quality of life of the elderly in the group art program, it was found that depression decreased and quality of life improved after participating in the program. Conclusions: This study was conducted by dividing the physically and psychologically deteriorated elderly into a control group and an experimental group. Sharing stories from past experiences had a positive effect on relationships with group members, and the elderly who have difficulty expressing their inner feelings through art, a non-verbal medium, had a positive effect on their satisfaction with their quality of life as they felt a sense of achievement after seeing the work.

Abstract

Purpose: This study analyzes factors influencing public interest in fermentation using Google search trends. Specifically, it examines how key elements such as oxygen, temperature, time, and pH influence fermentation-0related searches from December 2020 to September 2024. Research design, data and methodology: Data from Google Trends was collected under the Beauty & Fitness category for the terms “Fermentation,” “Oxygen,” “Temperature,” “Time,” and “pH.” Time series analysis was used to track trends over four years, and a correlation analysis was conducted to assess the relationships between these terms. A linear regression model was built to determine the influence of each factor on fermentation-related searches. The dataset was split into 80% training data and 20% testing data for model validation. Results: The correlation analysis indicated moderate positive relationships between fermentation-related searches and both time and pH, while oxygen had little to no correlation. The regression model showed that time and pH were the strongest influencers of fermentation interest, explaining 25% of the variance (R-squared = 0.25). Oxygen and temperature had minimal impact in predicting fermentation-related search interest. Conclusions: Time and pH are significant factors influencing public interest in fermentation-related topics, as shown by search trends. In contrast, oxygen and temperature, while important in the fermentation process itself, did not strongly affect public search behavior. These findings provide valuable insights for businesses and researchers looking to better understand consumer interest in fermentation products.

Abstract

In modern management, leadership has become an essential strategy rather than a choice, and interest in coaching leadership is increasing. Additionally, companies face inevitable tasks such as sustainable management and ESG management, which are crucial aspects of corporate social responsibility. This is a global phenomenon, and social value management activities play a significant role in evaluating the worth of modern companies. ESG management is assessed as a decisive indicator for investors' decision-making based on various global guidelines. ESG is an important issue not only for large corporations but also for small and medium-sized enterprises (SMEs). The government is actively expanding infrastructure and providing support to enable SMEs to lead ESG management among domestic companies. However, research on the ESG management of SMEs is still insufficient, and existing ESG studies have primarily focused on financial indicators. Therefore, the necessity for empirical studies involving various variables is emphasized. This study analyzed the impact of coaching leadership on organizational innovation behavior and performance in SMEs, mediated by ESG management. According to the analysis, coaching leadership positively influences organizational innovation behavior and performance by promoting ESG management in SMEs. The findings indicate that coaching leadership has a positive impact on organizational innovation behavior and performance, while persuasion and participation of internal members are essential for success. Moreover, this study provides practical and policy implications, offering specific strategies for SMEs to effectively implement ESG management and ensure sustainability, thereby supporting long-term growth.

Abstract

The purpose of this study was to investigate the impact of coaching leadership on ESG management performance through employee innovation behavior in the context of SMEs. Amid the lack of ESG-related research on SMEs, this study is significant in that it empirically verified that coaching leadership can contribute to the improvement of ESG performance of SMEs by inducing innovative behavior of employees. For the study, a survey was conducted on 244 employees of domestic SMEs. As a result of the study, it was found that coaching leadership partially had a positive (+) effect on ESG performance. Specifically, direction suggestion and competency development had a positive effect on the environment, social responsibility, and governance structure of ESG performance, but the relationship with performance evaluation did not have a significant effect. In addition, the direction of coaching leadership and competency development had a positive effect on innovation behavior, but performance evaluation was not significant. Innovative behavior had a significant positive (+) effect on all aspects of ESG performance (environment, social responsibility, and governance), and showed a significant mediating effect in the relationship between coaching leadership and ESG performance. This suggests that innovative behavior plays an important role in mediating the relationship between the sub-factors of coaching leadership and ESG performance. The theoretical significance of this study is to support the innovation behavior of members through coaching leadership in the SME field and to identify a path to increase ESG performance as a result. In addition, most previous studies on the relationship between ESG and innovation behavior have shown that innovation behavior is promoted by the influence of ESG, but this study confirmed that innovation behavior of SME members is an important factor in improving ESG performance. These results provided practical and policy implications for promoting ESG performance by leading the use of coaching leadership and innovation behavior in the SME field.
