This study measured the environmental efficiency of 21 international airports based on sustainability reports issued by each airport for 2018. As many sectors in the industry paid attention to social and environmental responsibilities, airport operators comprise one of the leading sectors that streamlined their facilities to become increasingly sustainable and environmental. Nevertheless, studies on the environmental operations of airports are insufficient compared with studies on economic or operational efficiency. Therefore, the current study aims to determine any possible improvement in the environmental inefficiency of airports with the utilization of directional distance function (DDF) and to examine operational efficiency with the application of the data envelopment analysis (DEA). The majority of airports have operated their facilities efficiently, but not all have effectively managed pollutants generated by airports. Furthermore, many airports can still potentially reduce CO₂ and water consumption. This study suggests several implementable environmental improvements to the aviation sector. Moreover, other industrial sectors may use the research as a benchmark for enhancing environmental efficiency.

Purpose: The purpose of this paper is to analyze accidents and potential risks occurring at container terminals and to conduct on safety management plans tailored to container terminals. Method: A model for establishing a safety management plan is presented through a case study of container terminal risk assessment and literature analysis. Result: According to the 'Statistics of Accidents in the Harbor Handling Industry', 2,800 people were killed or injured during port work for 10 years from 2011 to 2021. This corresponds to an occupational accident rate of one person every 1.5 days. As a method of improving these accidents and disasters, a highly effective safety management plan should be established to prevent the recurrence of accidents in accordance with the Special Act on Port Safety. It is proposed to establish a safety management plan that reflects the risk assessment of container terminals, safety organization, safety budget, safety rules, and safety education.

In accordance with the clean hydrogen-centered hydrogen industry development plan, technology development and demonstration operation of water electrolysis devices are being actively carried out. Risk assessments are performed on newly developed hydrogen-using facilities and supplies to identify potential hazard factors. However, in general, most industrial accidents are caused by operator's human error or incorrect work practices. Additionally, the possibility of accidents occurring during operation control, maintenance, and inspection increases. For this reason, for equipment developed for demonstration operation, the correct work methods for the main jobs of operator must be reviewed and work procedures must be prepared. Accordingly, in this study, we conducted a job safety analysis (JSA) on major jobs in the operation of water electrolysis facilities to study safe work methods and necessary measures.

This study evaluates the effectiveness of advertising copywriting using the artificial intelligence language model, ChatGPT, and explores its potential applications and limitations within the advertising industry. We established five key research questions and conducted in-depth focus group interviews (FGI) with university students in Busan. The findings reveal that there was no significant preference difference between copies written by ChatGPT and human copywriters. However, ChatGPT's copies were particularly effective in age-targeted advertising but showed limitations in gender targeting and reflecting cultural contexts. Additionally, consumer acceptance of AI copywriting was generally positive, though concerns were raised about the creativity and naturalness of AI-generated copies. This research provides practical insights into how AI can be utilized in advertising content creation and stimulates discussion on the appropriate use of AI technology and ethical considerations within the industry. These results offer important implications for both advertising professionals and the academic community.

Water plays the fundamental role in sustaining the living system. Water scarcity is mostly experienced dramatically by people living in poverty, most of them in rural areas and often in the poorest countries. Burundi has been identified as one of those countries. This study aimed to analyze and estimate the current and future water demands in the seven communes surrounding Kibira National Park (KNP) in Burundi. Sectors such as households, livestock, agricultural production and industry as the key water users in the study area were considered. The results showed an alarming increase in future water demand. Water demand by food crops increased to $288,779,060m^3/yr$ in 2020 and $306,018,348m^3/yr$ in 2050. Agricultural sector will be demanding the major available water in the seven communes surrounding Kibira National Park except Muruta and Bukeye which showed that water demand for tea industry was the highest in 2050. The water resources could be the greatest challenges for the overall development of the communities surrounding Kibira National Park. The current water resources may not be enough and therefore may not be able to meet the needs of those seven communities around KNP.

Public concern about potential environmental risks of agricultural business for the livestock production and processing is increasing. However, due to differences in general industry structural characteristics, such as farm production and waste management practices, the effect of environmental policies may differ from species to species as well as across size categories. I hypothesize that additionally the Hog subsector may be more responsive to (or a greater driver of) a changing environmental policy environment than the beef cattle subsector. As a result, I expect to see more evidence of sensitivity in the environmental policy milieu from hog-operation stocking and location decisions than with the beef cattle industry. The written stringency may not effective, instead state's willingness to enforce has directed and regulated. However, in presence of rapid structural change, just like hog, industry location is affected by state regulation. The environmental compliance cost may be a small portion of industry total cost and fixed cost of beef industry makes for them to take into account environmental compliance for their decision location making. The special movements of flog industry have chance to minimize the cost of the operation and they willing to locate less stringent place.

The purpose of this study is to analyze the determinants of start-ups by industry based on the theoretical background of entrepreneurship. For this purpose, regional industrial structure and local labor market structure are considered in order to focus on regional factors in addition to economic factors, income factors, and technological innovation factors. As an analyzed result, three theories of entrepreneurship generally agree with the determinants of industry - specific entrepreneurship. During the economic recession, the number of start-ups has increased. The intra-regional consumption and the local government expenditure per capita have also positive effects on the start-up. The incubation center has a positive effect on the start - up in the manufacturing sector. Therefore, the academic-industrial leading various incubation facilities should be activated in addition to the central or local government leading incubation centers, which is a part of the policy to support start-ups of central and local governments. In addition, population growth is a very important factor in terms of potential demand creation, and the characteristics of regional industrial structure and the effect of human capital within the region differ by industry. In the case of the manufacturing industry, the accumulation effect positively influences the start-up of the industry. In other service industries, the human capital variable had the greatest effect on the start-up when all other conditions are constant.

Potential risks of communicable disease outbreaks have significantly increased in the era of global society. However, contingency planning of local governments for communicable diseases is not prepared to the proper level in various governmental sectors of many countries. Human being has been remarkable advances in medical science and public health. However, Severe Acute Respiratory Syndrome (SARS) still remains as a very dangerous transmissible disease that has great potential to create catastrophic consequences of casualties. The SARS outbreak between November 2002 and July 2003 resulted in 8,096 known infected cases and 774 deaths with a mortality rate of 9.6% worldwide (WHO, 2004). It is regarded as one of the human health disasters. Since about sixty-six percent of total SARS cases in the world were reported in People's Republic of China, Korean tour industry was significantly affected as a neighboring country. The objective of this research is to investigate major factors of Korea entry data sets, and to analyze economic impacts of Korean tour business interruption due to the period of SARS outbreak with tourist cases of four countries: Japan, U.S.A., China, and Taiwan. Results from this research show the seasonal and long-term trends of entry data sets of four countries, and direct and indirect impacts of SARS to Korean tour industry.

Science and technologies develop rapidly and in conditions where it is difficult to predict both domestically and abroad, the rapidly changing business environment demands innovation. To strengthen the businesses' competitive edge, the key challenge is not to control but rather grant autonomy, allowing it to anticipate the future and actively deal with. This will allow to train and manage talented people with competence and abilities, which all links to the concept of the Super Leadership. Currently, our society is in the change due to the Fourth Industrial Revolution wave and paradigm related with high-tech industry, hence is in desperate need for creativeness and speed management. It is a time where risk and challenges coexist and is not a standardized environment. Businesses must make efforts in managing human resources and allow them to have leaderships compatible with the current era, giving them opportunities to face challenges. The necessity for Super Leadership is emphasized especially in the industry-orientated era, where new revolutionary technologies are emerging and existing technologies are being advanced and maximized, to cultivate the potentials of the members and secure competitive superiority for the best management and creation. Therefore, in this research, the empirical analysis of the relationship between Super Leadership of small and medium enterprises and the business outcome was conducted. Research outcome states that, in order to create a sustainable business outcome, enterprises need to invest more in developing leaderships and in accordance with it, promote talent. In order to survive and sustain growth in the period of endless competition like today, it is concluded that it is imperative to establish a powerful Super Leadership that will endeavor to engage and maximize the competence of members of the organization.
