This study is a study to systematize the R&D activities of social enterprises to derive a logical model of the R&D support policy, and aims to systematize the R&D activities based on the R&D demand survey and R&D activity analysis of social enterprises. R&D activities of social enterprises are at an early stage or are not systematic compared to general enterprises, so the process modeling method is used to group detailed activity elements to standardize and systemize them. As a result of the research, social enterprises are aware of the necessity and importance of R&D activities to secure competitiveness of products and services to increase social value, and because of their lack of R&D experience and capabilities, R&D specialized institutes (R&D planning institutes, government-funded research institutes), Universities, etc.) and are expected to improve R&D capabilities. The performance indicators of social enterprise R&D activities are derived in units of input-process-performance indicators through demand survey, activity analysis, and in-depth interview (FGI), and the logical model of R&D support policy is in the areas related to business strategy and performance.

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.

Despite the great interest in the metaverse from academia and industry, research so far has been focused on a specific area, and the background of the study is in the recognition that research is necessary from the perspective of the entire metaverse ecosystem. The purpose of this study was to derive the metaverse research framework and each component to study from the perspective of the metaverse ecosystem, and to study the development stage of the metaverse ecosystem. From an academic point of view, the ecosystem components were derived through the Metaverse IDC-Platform, a framework for applying Michael Porter's diamond model to the metaverse. From a practical point of view, the four components of the metaverse ecosystem interact with each other in terms of metaverse application and development. As the basis of this study, it can be used strategically because it is possible to identify areas for reinforcement in academia and industry and provide basic data for insight by closely examining the strengths and weaknesses of each component. The contribution of research is that it has created a foundation for research that has been limited to specific areas from an ecosystem perspective, unlike before.

This study was conducted to investigate the effect on subjective well-being and depression of the elderly with chronic diseases. Using data from the 15th Korea Welfare Panel in 2020, 3,910 people who responded that they had chronic diseases over the age of 65 were analyzed with stepwise regressions. As a result, the factors affecting the subjective well-being of the elderly with chronic diseases were in the order of satisfaction with leisure life, subjective health status, satisfaction with children relationship, satisfaction with family income, satisfaction with spouse. The explanatory power of this model was 32.0% (F=351.44 p<.001). And also, factors affecting depression were in order of subjective health status, satisfaction with spouse, satisfaction with social relationship, satisfaction with children relationship, satisfaction with leisure life, and satisfaction with family income. The explanatory power of this model was 21.4% (F=178.59, p<.001). Therefore, policy systems to support leisure life of the elderly with chronic disease and measures to induce participation in programs using community resources are needed. And health management programs and institutional support to improve subjective health status are also needed. In addition, it is expected that economic support at the national policy level and various program execution strategies and support personnel will be secured at the community level.

This study examined the relative influence of the five factors of the self-determination motivation on academic hatred. A total of 938 high school seniors (female 535, 57.0%) across eight schools in Seoul, Incheon, and Gyeonggi province were surveyed a month before Soo-neng (College Scholastic Ability Test). The findings of correlation analyses and hierarchical multiple regression analyses were summarized as follows. Academic hatred showed significant correlations with all the self-determination motivation factors except for introjected regulation. For hierarchical multiple regression analyses, starting with amotivation, the motivation factors indicating low level of self-determination were entered in order. In the final model, amotivation and introjected regulation had positive influence on academic hatred, and intrinsic regulation had negative influence on academic hatred. Specifically, introjected regulation which had no significant effect on academic hatred with amotivation and external regulation showed significant effect after identified regulation was added. Identified regulation lost its significant influence after intrinsic regulation was included. This study was meaningful in that it was the first study to clarify motivational characteristics of academic hatred based on self-determination theory. The study also presented its limitations, implications for school counseling intervention, and directions for future research.

As the importance of ICT use in education grows, this study analyzes the differences and characteristics of perceptions of educational fields and industries on the use of Edutech, and proposes policy suggestions for revitalizing Edutech by deriving requirements. Accordingly, a survey was conducted on 201 teachers and 100 companies, and IPA analysis, Borich's needs, basic statistics, and t-test were conducted to find out the necessity and utilization of Edutech. As a result, they were highly aware of the need for the use of Edutech, and perceived that the support or accessibility for Edutech was insufficient. Accordingly, direct exchange between on-site teachers and companies from the product development stage to utilization and follow-up management, professional support for the introduction of Edutech, simplification of the purchase process and deregulation, customized support and training programs according to the characteristics of teachers are required. In the future, it is necessary to consider the changes in education that will occur after COVID-19 and establish appropriate product development and spread strategies.

In this study, we developed a system to dynamically balance a daily stock portfolio and performed trading simulations using gradient boosting and genetic algorithms. We collected various stock market data from stocks listed on the KOSPI and KOSDAQ markets, including investor-specific transaction data. Subsequently, we indexed the data as a preprocessing step, and used feature engineering to modify and generate variables for training. First, we experimentally compared the performance of three popular gradient boosting algorithms in terms of accuracy, precision, recall, and F1-score, including XGBoost, LightGBM, and CatBoost. Based on the results, in a second experiment, we used a LightGBM model trained on the collected data along with genetic algorithms to predict and select stocks with a high daily probability of profit. We also conducted simulations of trading during the period of the testing data to analyze the performance of the proposed approach compared with the KOSPI and KOSDAQ indices in terms of the CAGR (Compound Annual Growth Rate), MDD (Maximum Draw Down), Sharpe ratio, and volatility. The results showed that the proposed strategies outperformed those employed by the Korean stock market in terms of all performance metrics. Moreover, our proposed LightGBM model with a genetic algorithm exhibited competitive performance in predicting stock price movements.

The "cognitive warfare," which has emerged as a result of the Ukrainian-Russian war, has already existed in the previous war and is now emerging as a major aspect of the war, its meaning and influence are increasing. Recognizing the emergence and importance of cognitive warfare and understanding the meaning and characteristics of cognitive warfare must be accompanied by victory in the modern war. After Russia's alleged involvement in the U.S. presidential election in 2016 drew attention, the Israeli-Palestinian conflict in 2021 confirmed its upward influence. In particular, 'cognitive warfare' using SNS played a major role in leading the war to its advantage and maintaining the initiative by selecting clear purposes and targets such as the international community, the people, and Hamas. This new pattern of war is gradually emerging as the world is hyper connected with the advent of the Fourth Industrial Revolution. It is expected that it will play a leading role in the future battle if it clearly recognizes the main contents of the new war, "Injijeon," and has the ability and ability to actively operate it.

The Riparian Buffer Zone(RBZ) is a sustainable social-ecological system created in the middle zone between water and land. For the RBZ, close communication with the local community is important, and it is necessary to promote it as a communicative environmental planning process. In this study, for the RBZ project, three strategies are presented as a communicative act to understand and implement planning. First, government-led projects were avoided and improved to a process in which citizens and stakeholders participated together, centered on local partnership. Second, it was intended to introduce design criterias in terms of enhancing the function of ecosystem services that citizens can sympathize with, and to increase acceptance and awareness through the planning of preferred spaces and facilities. Third, after a balanced plan for habitats, water cycle-based ecological environment, ecological experience and open space, citizens felt the restoration effect and value as an ecological resources, and a system was prepared to participate in the operation and management. This study will work as a process model based on citizens's participation. In addition, it will be possible to provide lessons for the change of the policy paradigm for the RBZ and the implementation of similar projects in the future.
