As cyberspace technologies advance rapidly, cyberspace security risks derived from new applications and technologies are becoming more complex and hidden. Establishing a unique cyberspace security model is a common practice to deal with complex security threats in China and abroad. However, existing cyberspace security models have problems such as unclear development directions, insufficient ability to analyze risks derived from new technologies, and lack of security capabilities required for cyberspace security defense assessment. This study evaluates existing cyberspace security models from the perspectives of technology, discipline, and industry, sorts out the characteristics and development context of the cyberspace security technology system, and clarifies the urgent problems existing in cybersecurity applications. Focusing on the perspective of cyberspace security technology, this study proposes a cyberspace security model system framework based on technical elements, using existing security technologies and emerging technologies to verify the security analysis capabilities of the system framework. This study further proposes the following development suggestions: (1) improving the core framework of the cyberspace security technology system, (2) promoting the industryuniversity-research integration in the field of cyberspace security, (3) promoting the formulation of core technology standards regarding cyberspace security, and (4) addressing AI security threats, thus to effectively deal with cyberspace security threats and enhance the cyberspace security capabilities of China.

Objective To systematiclly evaluate the relationship between assisted reproductive technology（ART） and autism spectrum disorders（ASD） in their offspring. Methods Systematic searches of PubMed, Web of Science, CBM, VIP, and CNKI databases were conducted to collect the cohort studies on ASD in ART progeny published from database establishment to April 1, 2022. After four independent reviewers screened the literature, extracted the data and assessed their quality with Newcastle-Ottawa scale（NOS）, a Meta-analysis was performed using Stata 15.1 software. Results Finally, 8 articles were included to assess the risk of ASD in 335507 offspring after ART（ART group） and 14233258 offspring of natural conception（NC group）. After excluding one study with greater heterogeneity by sensitivity analysis,the incidence of child with ASD in ART group was significantly higher than that in NC group（RR=1.06, 95%CI1.01-1.11, P

Space cameras play a pivotal role in various fields, such as astronomical exploration. When operating in orbit, these cameras encounter the relative motion between the target and the camera during the exposure, resulting in image motion, which affects the imaging quality. Therefore, it is necessary to compensate for this image motion. This paper investigates the in-orbit image motion compensation (IMC) method for space cameras with a long integration time based on a two-axis pointing platform. Firstly, the mechanical design of the camera is introduced. Secondly, the in-orbit IMC model for the camera is analyzed, and the angular motion needed for compensating for the image motion by the two-axis pointing platform are derived. Factors influencing the compensation accuracy are also analyzed. The effectiveness of the IMC model is verified through simulations. Finally, the in-orbit experimental results indicate that the energy concentration of the target star images obtained exceeded 70%, demonstrating excellent performance in space cameras and effectively enhancing imaging quality using IMC technology.
