China has achieved remarkable accomplishments in infrastructure construction, with its scale and speed ranking among the world's foremost. However, behind this rapid development, engineering design software, the "nerve center" of digital engineering, has long been dominated by foreign products, creating severe "bottleneck" risks due to external dependencies. The inclusion of the "Issue of Indigenous Engineering Design Software in the Infrastructure Sector" among the Top Ten Engineering and Technological Challenges for 2024 by the China Association for Science and Technology (CAST) underscores the extreme urgency of addressing this "Achilles' heel". This paper first reviews how foreign software established market dominance in China through first−mover advantages during the technological evolution from 2D drafting to 3D modeling. It then provides an in−depth analysis of the multidimensional risks arising therefrom, including threats to national information security, constraints on key core technologies, and stifled industrial innovation vitality. Building upon this, the paper systematically evaluates the profound "growth dilemmas" currently faced by domestic software in achieving autonomy in key core technologies, fostering a collaborative innovation ecosystem, and adapting to the strategic demands of "new quality productive forces". In response to this situation, this paper focuses on the core question of "How can indigenous engineering design software forge the 'Chinese cornerstone' of digital infrastructure?", rejecting superficial, symptomatic remedies and instead endeavoring to explore systemic breakthrough strategies for developing indigenous and controllable engineering design software. It emphasizes that this is not merely a technological challenge but a critical strategic imperative concerning the consolidation of national digital sovereignty, the cultivation of new industrial growth drivers, and the shaping of future national core competitiveness. The aim is to stimulate profound reflection within the industry on how to construct an autonomous, secure, and efficient "Chinese cornerstone" for digital engineering, and to foster consensus that drives proactive practical actions.

The territorial ecological security pattern refers to the planning and layout for ecological protection and restoration within the national territory to ensure ecological security. Analyzing the development process and characteristics of China's territorial ecological security pattern holds significant importance for promoting the construction and optimization of the national ecological security pattern. This research reviews the evolution of China's territorial ecological security pattern, clearly identifying the landmark events in each stage. It analyzes the current characteristics of China's territorial ecological security pattern and highlights the key aspects supporting the development of the national spatial ecological security pattern in the future. With the gradual deepening of awareness of ecological security theory and the development of socio-economic factors, the construction of China's territorial ecological security pattern has evolved from addressing the restoration of specific ecological issues to the development of the "two screens and three belts, " and further refined to the current "three screens and four belts." Nowadays, the construction of China's territorial ecological security pattern pays more attention to the integrity and functionality of geographical units in space. It emphasizes integrated governance of mountains, rivers, forests, fields, lakes, grasslands, and sands. And it pays more attention to the coordinated layout of ecological, productive, and living spaces to ensure harmony between economic development and ecological security. Given the background of climate change and increasing human activities, more efforts need to be invested in areas such as technological support, comprehensive management, risk response, and guiding public participation to provide solid support for the construction of the territorial ecological security pattern.

In recent years, major maritime countries and international organizations such as the United States, Russia, Japan, South Korea, the United Nations, and the European Union have issued multiple medium − and long−term ocean strategies and plans, intensifying efforts to promote the development of key marine science and technology fields, striving to make breakthroughs and progress in marine basic research, deep−sea technology, Arctic technology, shipping industry, marine renewable energy, and marine electronic information technology. In the medium to long term, the world's marine technology will present many new development trends. From the perspective of planning issued by major developed countries and international organizations involved in the ocean, this article summarizes and analyzes the main trends in the development of world ocean technology in areas such as ocean basic research, deep−sea fields, shipping industry, marine renewable energy development, and global ocean observation. It also summarizes that there are still many shortcomings in China's ocean technology, such as the gap between its basic research level and that of a world ocean technology powerhouse, insufficient innovation in deep−sea technology equipment, and reliance on imports for key core technologies. On this basis, it is suggested to strengthen the basic research of marine science and technology, and enhance the research and development efforts in key marine technology fields.

Based on the background and authoritative definition of "new quality productivity, " this study systematically examines the concept, connotation, theoretical framework, and implementation pathways of marine new quality productivity. The research highlights that marine new quality productivity is driven by marine scientific and technological innovation, relying on significant advancements in marine technology to achieve innovative allocation of marine production factors and promote deep transformation and upgrading of the marine industry, thereby fostering modern marine advanced productivity. The core connotation of marine new quality productivity is analyzed from three dimensions: macro, meso, and micro levels. Its fundamental characteristics encompass innovation–driven development, openness and integration, green and low–carbon practices, and efficient innovation. Guided by innovation, with "new" and "quality" as its starting and ending points respectively, the framework centers on "factor deepening, technological change, and industrial iteration" as its main trunk, supported by channels including the industrial system, green production, production relations, education, and technology, all underpinned by the "new development concept." This study proposes a pathway for realizing marine new quality productivity, prioritizing high–quality development, with scientific and technological innovation as the core driving force, high–quality labor force as the mainstay, and green development as the sole path.

The Global Ocean Observing System (GOOS), as a globally vital ocean observing network, is dedicated to integrating sustained ocean observing activities to provide unified data support for key areas such as climate policy, disaster early warning, weather forecasting, and marine resource management. With the continuous development of technologies, international scientific community and policy circles claim that the observation based on buoys, ocean gliders, ships, sea level, high−frequency radar, as well as animal sensors also faces a number of governance challenges, especially in areas under national jurisdiction. These challenges include the lack of coordination between legal procedures and actual operations, difficulties in advance notification, issues with the 'consent' process in disputed areas, and the absence of a domestic 'consent' process for the application of new technologies. Currently, international bodies such as the Intergovernmental Oceanographic Commission (IOC) have begun to take measures to address these challenges. In response, the author suggests that China accelerate the innovation and development of marine observation technology, actively participate in global marine observation affairs, and accelerate the cultivation of professional talents for international marine science and technology governance, in order to effectively respond to potential changes in global ocean governance.

The level of marine science and technology is an important indicator of a country's scientific and technological strength.

Magnetic induction (MI) communication has the characteristics of being less affected by the medium and having a stable channel, which can effectively solve the problem of excessive transmission loss of electromagnetic wave (EW) communication in extreme environments. However, as a near−field communication technology, the limitation of its near−field effective range leads to the restricted coverage of magnetic induction communication. Therefore, in−depth research on the magnetic induction boundary is of great significance for guiding the design and optimization of magnetic induction communication systems. This paper studies the spatial distribution of the electromagnetic field of a thin ring antenna in free space, comprehensively considers parameters such as antenna size, and proposes a decision parameter to give a stricter magnetic induction boundary. On this basis, the range of ring parameters under different frequencies and spatial angles is determined through error analysis, providing theoretical support for the parameter design of magnetic induction communication. By analyzing the variation laws of three verification parameters, namely the amplitude of wave impedance, the phase difference between the spatial electric field and magnetic field, and the spatial variation rate of the magnetic induction receiving intensity factor, with distance, the physical characteristics at the magnetic induction boundary are deeply revealed. The research finds that at the magnetic induction boundary, the magnetic field energy is dominant, the electromagnetic field distribution has not yet reached a stable state, and the physical property of rapid attenuation of the magnetic induction receiving energy is presented. Simulation results show that the proposed magnetic induction boundary formula can accurately describe the magnetic induction limit distance and ensure the effective performance of magnetic induction communication within the boundary range.

Major depressive disorder is a prevalent psychological disorder, and screening is currently based on depression diagnostic scales and physician interviews. Based on artificial intelligence technology, computer−aided depression detection is an emerging approach to depression screening. Aiming at the current status and shortcomings of traditional measurement tools, this paper reviews current computer−aided depression detection methods, discusses the current research status of depression detection datasets and depression detection methods based on multimodal data such as facial pictures, speech, and text, and summarizes and outlooks the advantages and challenges of computer−aided depression detection. Computer−aided depression detection can provide a relatively simple and standardized screening method with the potential to synergize with the widely used scale screening and physician diagnosis, but still faces the challenges of the insufficient interpretation of model parameters and features, the Chinese dataset to be expanded, and the small sample size of the existing dataset. In the future, researchers need to further improve the sample size and model accuracy of depression detection datasets, conduct theoretical and experimental analyses of feature extraction and model construction, and promote the clinical application of computer−aided depression detection.
