This study aimed to identify the factors that influence depression in stressed adults by age. Data were extracted from the 7th Korea National Health and Nutrition Examination Survey, covering 3,333 adults aged 20 to 59 years who were highly aware of stress. Linear regression analysis was performed using the IBM SPSS 25.0 program. The study found that in the case of people in their 20s, education level, health-related quality of life, obesity, weight change, smoking, and subjective body type were significant influencing factors, with an explanatory power of 60.3%. In the case of people in their 30s, gender, household income level, living with spouse, economic activity, health-related quality of life, food intake, obesity, alcohol consumption, smoking, and subjective health were significant influencing factors, with an explanatory power of 30.3%. For people in their 40s, household income level, living with spouse, economic activity, health-related quality of life, smoking, aerobic exercise, and subjective health were significant influencing factors, with an explanatory power of 34.4%. For people in their 50s, gender, education level, income, economic activity, health-related quality of life, protein intake, fat intake, high blood pressure, diabetes, weight control, aerobic exercise, subjective health, and subjective body type were significant influencing factors, with an explanatory power of 42.3%. Therefore, as it was found through this study that the factors affecting depression in stressed adults differ by age, it is necessary to establish an intervention strategy for each age when trying to lower depression in stressed adults.

Globally, in accordance with the goals set forth in the 2015 Paris Climate Agreement, each country has established and declared a reduction target for carbon neutrality by 2050. The roadmaps for establishing long-term greenhouse gas emissions development strategies and setting reduction targets have been announced. As the international community accelerates the transition to the net-zero society, 128 countries have declared net-zero by the end of 2020, and the net-zero declaration continues to expand around G20 member states. In December 2020, Korea announced the "2050 Net-zero Strategy" to establish a foundation for simultaneously achieving carbon reduction, economic growth, and improved quality of life for the people through active response to the net-zero, and pursuing policy tasks in stages to do this. Comprehensive carbon management is insufficient due to the lack of comprehensive carbon management due to the departure from the areas of mandatory reduction, such as the GHG energy target management system and the GHG emissions trading offset system implemented to reduce greenhouse gases in Korea. Currently, there is no cases for estimation or calculation of carbon dioxide emissions for the Mine Reclamation projects. It is reviewed the standard methods proposed by domestic and foreign carbon emission calculation methods and proposed appropriate carbon emission estimation methods for the Mine Reclamation projects in this study.

Recently, various digital technology issues such as e-Navigation, Maritime Autonomous Surface Ship (MASS) and Smart ships have constantly emerged in the maritime industry, based on the fourth industrial revolution. The International Maritime Organization is gradually tightening regulations for marine safety and marine environmental protection, and these strengthened regulations are leading to new maritime industries. Thus, the purpose of this study was to design a suitable model to analyze the industrial competitiveness of domestic autonomous operation technology industry, based on the Porter's diamond model. Based on a total of five evaluation factors and 13 detailed factors, the industrial competitiveness of the domestic autonomous operation technology industry was evaluated qualitatively and quantitatively. This industry, which is in the early stage of industrial development, was evaluated as 16.9 points relative to indexing industrial competitiveness. Currently, it is characterized by the simultaneous development of related regulations and core technologies, from the establishment of the scope of the industry. The industrial competitiveness evaluation considering these industrial characteristics is expected to serve as the basis for strategic support and new industrial policy, and impact a wide range of related industries such as shipping, logistics, ports, and shipbuilding and equipment industries.

This study examines the concepts and policy factors regarding gender-mainstreaming strategies and urban areas that have been discussed in the fields of international norms and development cooperation from the perspective of the Mexican government. It analyzes how gender-mainstreaming strategy is integrated and realized through Mexican law and key programs carried out by Mexico City. Through a literature review, this study builds upon previous research and theoretical discussions. In fact, Mexican federal government is considered to have successfully achieved "gender institutionalization." Within the framework of the law and institutions, the programs promoted by Mexico City aim to realize women's rights and meet their needs in the metropolis, while emphasizing a wider participation by citizens to realize these urban rights. In particular, the government of Mexico City is expanding on policies and programs that focus on strengthening the financial autonomy of women by understanding women's vulnerabilities as inequalities arising in the areas of the economy, space, and time.

This study is an exploratory study on the sustainable management of MICE events, and was conducted using the FGI method. Twelve experts in the MICE field, industry, and academia were selected as the subjects of the study. The reason is that understanding and specialty of those targets provides research reliability and validity. The study period was 3 months from June to August 2021. As a result, it is very important to prepare a sustainable development strategy in the MICE industry, and in particular, the need for guidelines to be practiced during event operation from the organizer's point of view was derived. In addition, to derive items that can be used in practice based on the theoretical basis, and it was necessary to derive research results using internationally recognized Sustainable Development Goals (UNSDGs) and sustainable MICE research developed in the fields of tourism and MICE. Therefore, through the verification of such experts in the field of MICE, theoretical and practical guidelines from the perspective of the organizer that can be used when holding MICE were developed. The results of the study will provide implications for establishing more effective strategies for hosting sustainable MICE events in the future.

The study is to estimate the social costs of premature deaths due to nuclear power plant(NPP) accidents, by resorting to the contingent valuation method(CVM) which is used to estimate the value of a statistical life(VSL). The VSL estimate is about 3.55 billion won, which is multiplied by some 1.8 million premature deaths due to the accidents in world history of NPP, to get a maximum social cost of 1,952 trillion won. This estimate is equivalent to the 2022 real GDP of Korea. The annual average number of premature deaths and the resulting average social cost is 26,000 and 28 trillion won, respectively. The social cost of premature deaths due not only to accidents, but also the air pollutants from fired power plants(FPP) during 1987~2021 is estimated to be 26,919 trillion won. This is equivalent to 2021 US GDP, and is about 3,000 times higher than that for NPP of 9 trillion won. In 2021, the estimated social costs of FPP and NPP are 1,075 trillion won and 292 billion won, respectively. For South Korea, the study suggests to adapt an energy mix of increased share of electricity production for NPP relative to FPP, given that the 2050 carbon neutrality strategy of Korea is expected to lead to an increased share of renewable energy in electricity production. The study emphasizes accumulating the number of CVM-based VSL studies to ensure efficient energy policies.

As part of open science, the government adopts a national research data sharing and utilization strategy, forms a governance system at the national level, and promotes policies for research institutes to implement. Although the policy for managing research data is carried out centering on the academic world, it is insufficient compared to developed countries, and even this is a reality in which researchers do not have enough awareness to introduce it to the field. The purpose of this study is to understand the research data management status of researchers in each academic field. Academic fields consisted of four fields including Library and Information Science, Statistics, Ecology, and Korean Musicology, and the current status of data management was identified through a survey. The current status of research data management was analyzed from the perspective of research data production, sharing and management, saving, preservation and reuse. As a result of the study, it was found that there were differences by discipline in terms of data production, data sharing and management, data preservation, and data reuse, except for data savings.

The representative cultural heritage showing relatively clearly the growth and development of the Mahan culture in Jeollabuk-do is the tombs in Sangun-ri, Wanju. The tombs were excavated in the early 2000s; however, little effort has since been made to investigate or preserve the wider area around the tombs. Thus, only the status quo has been maintained except for the conservation of a few relic parks. In recent years, active cultural management has become necessary to maintain the historic areas in the Mahan cultural region, so these tombs are once again receiving attention. To further the preservation efforts in the area, it is important to actively discuss budget adjustments, consider additional investigation, and re-examine the academic value of the historic site. Practical limitations mean that it is necessary to approach the conservation strategy in stages. The first step is to have the areas of cultural interest and any adjacent lands urgently designated as provincially protected cultural heritage. Consequently, historically important areas on private land should be identified and purchased. Thereafter, a preservation plan should be established to reinforce the historical value of the sites as nationally designated historic sites. This can be achieved through the restoration of the landscape adjacent to the historic sites, as well as additional investigations and designation of sites in surrounding areas. These goals can only be achieved with the active interest and support of relevant institutions.

The numbers of occurrences and the amount of spills of marine oil pollution have increased, and accordingly, it is necessary to secure additional control capabilities. Therefore, it was intended to present an empirical basis for improving the overall idle capacity through the relocation of control ships existing in each region. First, the marine pollution index was derived and the control capability compared to the marine pollution index of each region was compared to examine the appropriateness of the deployment of control ships. The marine oil pollution risk index was derived by multiplying the nine items that cause marine pollution by the weight derived by experts. We checked the control capacity (A) compared to the marine pollution risk index (F) for each sea area. Mokpo (F:13.4, A:1.9), Busan (F:14.3, A:6.4), and Yeosu (F:21.5, A:16.6) are the areas that lack control capabilities compared to the marine pollution risk index. On the other hand, the areas that have room for control compared to the marine pollution risk index for each sea area are Masan (F: 5.9, A:13.3), Gunsan (F:1.7, A:8.3), and Jeju (F:2.7, A:6.9). Therefore, for improving the standardized control capacity proportional to the risk of marine pollution nationwide, it is suggested that the control ships of Masan, Gunsan, and Jeju should be relocated to Mokpo, Busan, and Yeosu, which lack control capacity.

This study is to suggest the direction of the spatial change of the university library based on the trend of the spatial change in the university libraries and a survey on the perception of the librarians. For this purpose, the characteristics of the spatial change of the university libraries from 2000 to 2020 were analyzed, and the problems of the spatial change of the university libraries were identified through a survey. As a result of the survey, there was a total of 99 spatial changes in the university libraries nationwide over the past 20 years, including new construction, extension and remodeling. In recent years, it was found that due to the university's budget tightening policy, the university libraries focus on remodeling rather than new construction or extension. The characteristics of the spatial change were analyzed as follows. First, the resting areas have been expanded in the libraries. Second, The libraries are in pursuit of pleasant and comfortable atmosphere. Third, the libraries aim to establish an innovative and creative space. All these changes have been made in order to accommodate the requests of users and increase the number of users. It was also found that spatial change has advantages in these two points: providing various spaces and increasing the number of library visitors. On the other hand, spatial change has the problems such as the increased cost of maintaining the facility and the lack of management manpower. Additionally, a few more problems of spatial change are pointed out: first, spatial change only reflects the trend of the times without making a big change in the services and the actual value of the university library. Second, it has made university libraries standardized losing each library's own characteristics. This study suggests that the spatial change of the university library should secure the distinctiveness of the university library, accommodate various changes, and aim for the symbolism that can prove the value and existence of the university library.
