The era of the fourth industrial revolution is an era in which existing boundaries are broken down by the convergence of technology and knowledge, and complex solutions at various levels are required. As a result, convergent creative capabilities are considered a major condition for talent. In order to foster these creative convergence talents, it is necessary to set goals for liberal arts education at universities. Accordingly, the research was aimed at developing subjects to develop creative convergence capabilities by analyzing the current and complex aspects of various fields where artificial intelligence technology is used.

Xi Jinping’s 3rd term began since the CCP’s 20th Congress and the 1st plenum of the 20th CPC Central Committee. Xi Jinping’s 3rd term is characterized as Xi’s absolute dictatorship and Xijiajun’s monopoly of political power. The dictatorship system has multiple implications on China’s politics. The most significant implication is substantial degeneration of China’s institutionalization in term of political power. It is to bring about increasing inflexibility in political and policy decision making processes and degenerating political resilience of the Chinese politics. Also, it means rising instabilities in China’s politics, economy, and foreign policy. The paper examines the Xi’s 3rd term system focusing on the degeneration of political institutionalization. Lastly, it anticipates policy directions of the Xi’s 3rd term, and then draws its political implications.

The effect of the Fe/Co ratio on the catalytic performance of Fe–Co/alumina catalysts has been investigated in the production of high-calorific synthetic natural gas (SNG) from syngas. Fe–Co/alumina catalysts with different Fe/Co molar ratios were synthesized by the co-precipitation method and characterized using XRD, BET, H2-TPR, Raman, XAS, and XPS. At higher Fe/Co ratios (≥2), the calcined Fe–Co/alumina catalysts were mainly composed of α-Fe2O3 and CoFe2O4. The presence of Co improved the dispersion of iron oxides and the catalyst reducibility under H2 atmosphere. The Fe–Co/alumina catalysts partially formed FeCo alloys when they were reduced at 350 °C under H2. The formation of FeCo alloy destabilized the iron carbide phase and suppressed the carbon chain growth. These Fe–Co/alumina catalysts were efficient in producing high calorific SNG with a heating value of over 60 MJ/Nm3.

3D Pose Tracking Using Particle Filter with Back Projection-Based Sampling
이지용,정문호,이중재,김강건,유범재 제어·로봇·시스템학회 2012 International Journal of Control, Automation, and Vol.10 No.6
This paper explores pose tracking with a 3D object model using a particle filter. In tracking an object with a particle filter, a problem of high dimensional solution space often appears. In a huge space, a search process is tedious and falls foul of the exponential computational complexity. We propose the back projection-based sampling with a depth map from a stereo camera, which reduces the solution space significantly. In addition, we treat a method that constructs the 3D model used in this paper. Results are shown for tracking the pose of several objects.

트럼프 집권 2기 미중관계 변화의 국제지정학적 함의 분석
이지용 신아시아연구소 2025 신아세아 Vol.32 No.2
현재 동아시아 및 한반도를 둘러싼 안보환경 변동양상의 키워드는 ‘위험지대(Danger Zone) 진입’으로 요약할 수 있다. ‘위험지대(Danger Zone)’란 급상승하던 국력상승이 정점에 도달해 있는 중국이 공세적이고 급진적인 도발에 나설 가능성이 매우 높은 구간을 의미한다. 이러한 상황이 전개되는 가운데, 트럼프 집권 2기에는 미국의 대내외 정책에 매우 큰 변화가 예고되어 있다. 특히 대외정책에서 미국의 중국정책이 트럼프 집권 1기와 바이든 행정부 시기보다 더 큰 폭으로 변화할 것으로 전망된다. 본고는 트럼프 집권 2기 미중관계 변화를 첫째, 국제지정학적 접근, 둘째, 미중관계 변화에 대한 역사적 접근을 통해 식별해 보는 분석을 시도한다. 끝으로 미중관계 변화의 국제지정학적 함의가 한국에 주는 시사점을 도출한다. The keyword encapsulating the shifting dynamics of the security environment surrounding East Asia and the Korean Peninsula at present can be summarized as the "entry into a Danger Zone." The term "Danger Zone" refers to a phase in which China, having reached the zenith of its rapidly ascending national power, is highly likely to engage in aggressive and radical provocations. Amidst this unfolding scenario, the second term of the Trump administration is anticipated to usher in substantial changes in U.S. domestic and foreign policy. In particular, U.S. policy toward China is expected to undergo a more significant change against China compared to both the first Trump administration and the Biden administration. This paper attempts an analysis to identify the changes in U.S.-China relations during the second Trump administration through two approaches: first, an international geopolitical perspective, and second, a historical perspective on the evolution of U.S.-China relations. Finally, it derives the geopolitical implications of these changes in U.S.-China relations and their implications for Korea.
