This paper aims to advance renewable energy cooperation among China, Korea, and Japan by offering strategic recommendations to bolster joint initiatives in emerging energy sectors. The research identifies key challenges hindering collaborative efforts, including insufficient infrastructure, reduced government budgets post-COVID-19, and historical disputes. To address these issues, we propose several strategies: enhancing policy coordination to develop clearer and more specific plans for renewable energy cooperation; establishing a robust cooperation framework to reduce political risks; expanding technological collaboration through the construction of an ultra-high-voltage power grid across Northeast Asia; fostering technology partnerships via Clean Development Mechanism projects; and utilizing blockchain technology and climate crowdfunding to enhance financing options. These strategies will effectively promote cooperation among China, Japan, and South Korea in the field of renewable energy.

The purpose of this study is to identify users' perceptions of the Coupang Eats app, which is maintaining growth in the delivery app market, and to derive improvements by identifying factors that induce and strengthen positive/negative perceptions. As a result of the study, first, the frequency and connection centrality of the word 'fast' were high, indicating that the speed of the Coupang Eats service is receiving a lot of attention. Second, as a result of CONCOR analysis, the areas of interest of users were identified by clustering the main keywords of the Coupang Eats app review data and dividing them into groups. A total of four groups could be identified: 'benefit service', 'satisfaction', 'inconvenience', and 'other', indicating the areas of interest of users. Third, through emotional vocabulary analysis, it was confirmed that there were more positive vocabulary than negative vocabulary in the Coupang Eats app review data. Fourth, the result of document sensitivity classification also confirmed that positive reviews appeared more than negative reviews. Finally, a text analysis was conducted on positive and negative reviews classified according to the document sensitivity classification to derive factors that induce and strengthen positive and negative perceptions.

Colleges/universities have experienced challenging learning environments such as online non-face-to-face classes in pandemic situations such as COVID-19. Through this experience, colleges have become aware of the importance of digital-based learning such as online classes, and accumulated know-how by attempting various technologies and methods to increase the learning effect. Artificial intelligence (AI) technology is rapidly developing after the pandemic, putting us in the era of digital transformation in which the speed of education cannot surpass that of technological development. As a result, learners require digital literacy competencies in addition to ethics regarding higher levels of AI tools, as well as problem-solving skills using various digital-based tools at the same time. Accordingly, this study designed a digital collaboration problem-based learning (DC-PBL) model for college students to solve common problems by collaboratively interacting with one another using various digital tools. To this end, an instructional model was developed based on literature research, which was validated by the opinions of four experts and revised and supplemented by collecting expert opinions, after which the final model was presented.

The purpose of this study was to compare the effectiveness of different CPR methods by reenacting the case of a firefighter in cardiac arrest on fire scene. The research subjects were 62 firefighters from Gyeonggi-do, and 31 in the experimental group were given the (FD-CPR) training program for firefighters downed on fire scene and 31 in the control group were given the Korean Association of Cardiopulmonary Resuscitation and CPR for the general public (KA-CPR) training program for 80 minutes each, and the difference in the amount of change in performance from before to after the training was compared. The analysis showed that the experimental group had a significant decrease in time to first chest compression (t= -48.76, p< .001), compression depth (t= -9.05, p< .001), compression rate (t= -11.26, p< .001), hands off time (t= -29.26, p< .001) and a significant increase in chest compression position accuracy (t= 23.61, p< .001) than the control group. Therefore, FD-CPR has a greater effect on CPR performance compared to KA-CPR, so if it can be added to the training courses for firefighters at Fire Service Academy nationwide, it will contribute to improving the survival rate of victims of cardiac arrest firefighters downed at the fire scene.

Objective: This study aimed to examine the associations between unwanted sex and demographic, disability, daily living, and psycho-social characteristics among Korean adults with Disabilities. Subjects: The participants were 4,335 persons with disabilities aged 19 and above. Methods and Procedures: 1st Wave data from the Panel Survey of the Life of Persons with Disabilities (2018) was used, and rare event logistic regression analysis was used to test the association between unwanted sex and independent variables. Results: The prevalence of unwanted sex among adults with disabilities was low because of measuring the past year, not a lifetime. Marital status, economic poverty, employment status, use of social welfare facilities, use of SNS, and experience of sexual life counseling were significant predictors of unwanted sex. Conclusion: Nationally representative data that can examine the lifetime prevalence of unwanted sex among adults with disabilities is needed to estimate the number of people who experienced unwanted sex more accurately. There is also a need for enhanced sexual violence counseling centers for a safe sexual life among adults with disabilities.
