The Role of Vietnam in Relation to North Korea's International Reintegration and Innovation Processes from the 2010s to the Present

This study explores and analyzes the relationship between Vietnam and North Korea since the beginning of the 21st century, in the context where both countries have opted for different foreign policy strategies following the Soviet Union's collapse. Vietnam has conducted economic reforms and openness under the "Đổi Mới" policy while maintaining a one-party political system, whereas North Korea continues on a path of isolation with its policy of nuclear weapons development under the constraints of international sanctions. The relationship between Vietnam and North Korea has experienced many fluctuations, particularly after Vietnam established diplomatic relations with South Korea in the 1990s. However, since the beginning of the 2010s, this relationship has gradually been restored and strengthened through high-level visits and cooperative initiatives. Vietnam has played the role of a mediator, not only reducing tensions on the Korean Peninsula but also supporting North Korea in its process of international integration. The study emphasizes Vietnam's role in promoting regional stability and development, while facing challenges and opportunities in balancing relationships between North Korea and other countries such as South Korea and the United States. Through this, Vietnam not only strengthens bilateral relations but also contributes to the process of innovation and international reintegration of North Korea.

Renewable Energy, Energy Efficiency, and Energy Resilience: A Case Study of Japan

This study develops energy resilience (ER) indices for Japan and analyzes its changes in response to historical events. The proposed composite indices incorporate renewable energy, climate change, energy efficiency, and energy security. Changes in the indices are argued along with historical events and policy measures. The insights gained from this longitudinal analysis can inform future energy policy decisions in Japan and provide valuable guidance for other resource-poor countries facing similar ER challenges.

Research on Business Performance of Commercial Bank's Digital Transformation

This paper takes six large state-owned banks from 2019 to 2022 as the research object, selects the number of financial funds, labor, physical capital and fintech personnel as input indicators, and selects total loans and financial asset investment as output indicators, and combines the DDF directional distance function with the profit performance decomposition model. The profit change of state-owned banks is further decomposed into three aspects: quantity effect, price effect and productivity effect, and the impact of digital transformation of state-owned banks on operating profits is measured with fintech input as the core index. Finally, the average value of quantity effect, price effect and productivity effect of state-owned banks is compared and analyzed. To provide relevant suggestions for the feasible path of digital transformation of state-owned banks in the future.

Designing Tracking Footwear Utilizing LoRaWAN Technology

By utilizing LoRaWAN (Long Range Wide Area Network, LoRaWAN) technology, this study concentrates on developing advanced tracking footwear to ensure the safety of hikers and senior citizens with dementia who tend to wander. In expansive terrains where traditional trackers fail, LoRaWAN is ideal because of its minimal power usage and broad range. The sneakers incorporate robust LoRaWAN transmitters, using the sturdy nature of the shoes and ensuring the devices are discreet and active. The shoes incorporate GPS-enabled microchips, accelerometers, and pressure sensors that are crucial for monitoring the wearer's movements and detecting emergencies, providing essential real-time data. The research confirmed the system's effectiveness through extensive testing in varied environments and realistic scenarios, showing that it delivers reliable and precise location tracking. Facilitating immediate location identification in emergencies enhances securing at-risk individuals and shows LoRaWAN's potential to improve personal safety devices over existing, less reliable options. Future efforts will aim to refine the technology by making devices lighter, more energy-efficient, and user-friendly for broader applications, increasing public safety and affecting lives.
