This study was established to provide basic information necessary for ecological management to restore the naturalness of black locust (Robinia pseudoacacia L.) plantations located in the mountains of Gyeongbuk, Korea. Using vegetation data collected from 200 black locust stands, vegetation types were classified using the TWINSPAN method, the spatial arrangement status according to the environmental gradient was identified through DCA analysis, and a synoptic table of communities was prepared based on the diagnostic species determined by determining community fidelity (Φ) for each vegetation type. The vegetation types were classified into seven types, namely, Quercus mongolica-Polygonatum odoratum var. pluriflorum type, Castanea crenata-Smilax china type, Clematis apiifolia-Lonicera japonica type, Rosa multiflora-Artemisia indica type, Quercus variabilis-Lindera glauca type, Ulmus parvifolia-Celtis sinensis type, and Prunus padus-Celastrus flagellaris type. These types usually reflected differences in complex factors such as altitude, moisture regime, successional stage, and disturbance regime. The mean relative importance value of the constituent species was highest for black locust(39.7), but oaks such as Quercus variabilis, Q. serrata, Q. mongolica, Q. acutissima, and Q. aliena were also identified as important constituent species with high relative importance values, indicating their potential for successional trends. In addition, the total percent cover of constituent species by vegetation type, life form composition, species diversity index, and indicator species were compared.

This paper describes the comparative results of measured and predicted values for the horizontal displacement of earth retaining wall based on two field cases, In order to examine the application of lateral earth pressure to the earth retaining wall considering the typical ground characteristics (clinker layer) in Jeju. The prediction of the lateral earth pressure causing the horizontal displacement of the retaining wall was performed by elasto-plastic analysis using Rankine earth pressure, Terzaghi & Peck modified lateral earth pressure, and Tschebotarioff lateral earth pressure. As a result, it was confirmed that the maximum horizontal displacement predicted at site A was about 5 times larger than the measured value, and the ground with maximum horizontal displacement occurred by the prediction was found to be the clinker layer. In the case of site B, the predicted value was 4 to 7 times larger than the measured value. In addition, the ground with maximum horizontal displacement and the tendency of horizontal displacement were very different depending on the prediction method. This means that research on lateral earth pressure that can consider regional characteristics needs to be continued, because it is due to the multi-layered ground characteristics of the Jeju area in which bedrock layers and clinker layers are alternately distributed,

Understanding professional baseball fans' expenditure is expected to provide fundamental marketing information that help increase each team's marketing profits and values and produce a better economic impact on its community. In this regard, this study employed a survey method with a total of 372 residents located in Changwon. A questionnaire included factors such as demographics, consumption patterns and perceived socio-psychic effect(PSE), all of which were derived from literature review. A binary logistic regression was modeled with a dichotomous dependent variable, expenditure(30,000 won more or less). The following were input in the model as the independent variables in order to see the relationships; gender, marriage, education, occupation, income, location, age, leisure type, distance, companion, transportation, interest, and PSE. The results of the logistic regression analysis are as follows. Overall, the model was statistically significant, χ²(21, N=372)=59.159, p=.000. Cox and Snell R² was reported as .147 and .200 respectively. So, the model accounted for between 14.7% and 20.0% of the variation in expenditure. Among the independent variables, income, location, companion, and PSE were found to be the significant factors to expenditure. For income, subjects with 2 million won less of income, compared to those with 4 million won more, were .38 times less likely to pay the money of 30,000 won more. For location, subjects in Masan, compared to those in Jinhae, were 3.49 times more likely to pay 30,000 won more. Subjects in Changwon, compared to those in Jinhae, were 3.05 times more likely to pay 30,000 won more. For companion, people visiting the stadium alone, compared to those with friends/colleague, were .36 times less likely to pay 30,000 won more. For PSE, the odds of 30,000 won more paid increased by 1.37 times with one-unit increase in PSE.

The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.

This study was conducted to design a financial system for the sustainable life of mankind. Human society faces a constant crisis and leads a life while overcoming it. The polarization is intensifying in the process of overcoming the economic crisis or crisis caused by the virus. In a society adopting the capitalist economic system, it is a common phenomenon that polarization intensifies with the passage of time, but since the intensification of polarization can destroy human society as a community, active countermeasures are required. The purpose of this study was to prevent the deepening of polarization by redesigning important financial-related systems from the perspective of human life and maintenance of human society. Through the history of mankind, monetary and financial systems related to sustainable society have been analyzed, and a financial system model that is ideal for the modern and future society and is sustainable in the long term has been derived. The conditions for a long-term sustainable financial system should be a model that can solve the problems of the current system, such as deepening polarization, and a model that is faithful to the characteristics of the modern economic society and the essence of sustainable life. And it can be sustainable only if it is based on the common principles of human society. It should be a model that guarantees core values such as growth and equality that human society demands. After analyzing the problems of the current economic system and analyzing the conditions required for the new system, the basic axioms that the new financial system should be based on were presented, and a desirable model was derived based on this. The structure of the derived model and the specific operation model were presented. In the future, follow-up studies are needed to concrete this model.

This study was conducted to derive a society and education system model that will improve the happiness and sustainability of human society. An ideological model for making human society a happy society was derived, and a society and education system structure and operation model based on this was presented. A fair society, a justice society, a mutually considerate society, and a society where individuals are happy are the conditions for a sustainable society. After analyzing the current situation of freedom and equality pursued by capitalism and democracy, which are currently adopted by most societies, an improvement model was derived from the perspective of a sustainable society. The cost of freedom and equality were analyzed and a new alternative system was discussed. The social solidarity and class mobility issues were discussed together and servicism was derived as an alternative solution. It is a system in which two opposing opponents of individual freedom and social norms form a symmetrical balance, and material and spiritual values are balanced. Servicism is a dynamic balance model. That is, the dimensions of time and space are involved. It is a model that maintains a thorough balance through a dialectical process as time and space change, and one value can dominate the other at a specific time or space. The service-oriented society and education system is a system that simultaneously pursues the goals of individual happiness and sustainable development of the social community.

In this study, we investigated the effects of ego integrity on QoL(Quality of Life) of elderly living alone, where we focused on moderating role of SF36 health factors. To investigate the cause and effect of factors, we purposively collected 282 samples from senior welfare centers in Jeonju city and exploited reliability analysis, confirmatory factor analysis and SEM(Structural Equation Modeling) for 265 cases excluding some cases with missing values. As the results, first, we confirmed ego integrity was positive predictor of QoL. Second, it was proven that the effect of ego integrity on QoL of elderly living alone was stronger in the lower physical functioning group than higher physical functioning group. Third, we also verified that the group with more difficulties in activities or work as a result of poor physical health showed higher effect of ego integrity on QoL. Based on the results, we could explain the reason of conflicts regarding how elderly's health influenced on ego integrity. Also, in the practice of intervention to elderly's problem, we found the health factors could be an indicator of direction or effect of the intervention

Korea has undergone rapid modernization and globalization process in the last few decades. The purpose of this study is to explore how shifting traditional values are impacting Korean elderlies and their perceptions of aging experience. In order to understand how changing social and cultural practices are affecting older adults, the similarities and differences among Korean elderlies living in three different geographical locations are examined in a multidimensional comparative framework. Life story interviews were conducted with 30 Korean elderlies (10 urban residents in Korea, 10 rural residents in Korea, and 10 residents in the US). Paying attention to within-group variation, this study particularly focused on analyzing the psychological, social, emotional, and spiritual experiences that made lives meaningful and resilient in old age in spite of physical decline. Based on analysis of narrative, the following major areas were identified as having positive or negative influence on aging experiences: physical health, emotional health, family relationship, work, leisure/social activity, and spirituality. Common themes of aging well across all settings included: "life not indebted to their offspring," "physical and mental health," and "dying well." Spirituality played a critical role in cultivating perspectives on life and accepting aging process, which were rooted in specific religious traditions participants identified (e.g., Christianity or Buddhism). Interesting differences in the meaning of work and leisure were also found between elderlies residing in Korea and the US immigrant context. One unique factor continuing to negatively affect Korean elderly in rural community was related to shame of not obtaining higher education. Implications for future research are also addressed.

The present research aimed at investigating the impacts of volunteer activities on self-development and sociability-development. In study 1, the scale comprised of 15 items was developed to measure the meaningfulness of volunteer activities. An exploratory factor analysis was conducted on the data obtained from 428 undergraduates (193 males and 235 females). A confirmatory factor analysis was then conducted on the data obtained from 280 undergraduates (124 males and 156 females). In study 2, the impacts of volunteer activities on 947 undergraduates (461 males and 486 females) were analyzed in terms of self-development and sociability-development. Self-development consisted of self-evaluation, self-esteem, and quality of life. Sociability-development consisted of pother-acceptances, sense of community, and democratic citizenship. The results showed that not more volunteer activities itself but more meaningfulness of those activities had stronger relations with self-development and sociability-development. Finally, a values of the undergraduates internalized for volunteer activities and their levels of self-development and sociability-development expectation were discussed.

Located in the sea area between South Korea, North Korea, and China, the Yellow Sea plays an important role from a geopolitical perspective, and recently, as the use of marine space in the Yellow Sea is expanding, its social and economic values have been increasing further. In addition, owing to rapid climate changes, the need for joint response and cooperation between Korea and China is increasing in various fields, including changes in the marine environment and marine ecosystem and generation and movement of air pollutants. Accordingly, in this study, core topics were derived from research papers with the Yellow Sea as a keyword, and research trends to date were explored through author network analysis. As a specific research method, research papers related to the Yellow Sea published between 1984 and 2021 were extracted from the Web of Science database and were classified into four periods to derive core topics using topic modeling, a type of text mining. Furthermore, the influences of major research communities, researchers, and research institutes in the appropriate fields were identified through analyzing the author network, and their implications were presented. The analysis results indicated that the core topics of research papers on the Yellow Sea had changed over time, and differences existed in the influence (centrality) of key researchers. Finally, based on the results of this study, this study aims to identify research trends related to the Yellow Sea, major researchers, and research institutes and contribute to research cooperation between Korea and China regarding the Yellow Sea in the future.
