The prevention and treatment of rare diseases is an important public health issue in China. Rare diseases are characterized by diverse types, complex conditions, and heavy burdened to patients, leading to a series of issues in the urgent demand in prevention and treatment of rare diseases in terms of individuals′ health and the national responsibilities. Related legislation is an effective way to promote multi-disease prevention and treatment of rare diseases, and patients′ protection in multi-level. We tease out and analyze the legal system on national and local level related to rare diseases, and recommend the coping strategies and give suggestions to improve and optimize the legal system for the prevention and treatment of rare diseases from the three dimensions of completeness, normalization and feasibility of the legislation, hoping to improve the competence of China′s rare disease prevention and treatment and raise the level of protection for the patients.

IntroductionPilots’ safety attitude is crucial for aviation safety. Current research shows a correlation between perceived stress and safety attitude, yet the mechanism underlying this association remains unclear. Against the backdrop of heightened attention to pilots’ stress, this study aims to thoroughly explore the inherent connection between pilot safety attitudes and their perceived stress, offering targeted insights into preventing and addressing safety attitude issues arising from pilot stress.MethodsThrough path analysis of questionnaire data from 106 civil aviation pilots in China, this study systematically investigates the roles of job burnout and cognitive flexibility in the relationship between perceived stress and safety attitude. The study reveals the chain-mediated mechanism of these two factors.ResultsThe results demonstrate a significantly negative correlation between pilots’ perceived stress and safety attitude, with cognitive flexibility and job burnout fully mediating this relationship, and cognitive flexibility affecting job burnout. A detailed analysis of the three dimensions of job burnout reveals varying impacts of emotional exhaustion, depersonalization, and reduced personal accomplishment on the aforementioned path. The research model exhibits a good fit (GFI=0.902), providing new theoretical perspectives on the association between pilots’ perceived stress and safety attitude.DiscussionThe findings offer practical implications for improving pilots’ safety attitude by proposing targeted measures to alleviate the adverse impacts of perceived stress on safety attitude, thereby promoting aviation safety.

Hoque and Noon claim that many workplace equal opportunities policies in the UK are merely ‘empty shells’. This article will discuss this claim and consider the extent to which radical equal opportunities policies may address these shortcomings. Based on the analysis, it is concluded that contemporary society is still far from the goal of fully addressing inequality, and the EO policies still face the problem of the ‘empty shell’.

In recent years, the new energy vehicle (NEV) industry has rapidly grown and become a vital part of the automotive sector. Supply chain finance plays a critical role in the NEV industry as it affects the operation and development of the entire industry chain. The supply chain of NEVs is different from the traditional automobile industry due to its complexity, fragility, and forecasting difficulties. Managing the risks associated with supply chain finance in the NEV industry presents new challenges. Commercial banks need to establish scientific risk assessment models and take preventive measures to ensure the provision of financial services while safeguarding their funds. This study focuses on the supply chain financial services of NEVs provided by commercial banks. It employs various methods to assess financial risks, establishes a risk index model, and uses the analytic hierarchy process, entropy weight method, and fuzzy comprehensive evaluation to determine weights and provide risk assessment opinions. The proposed evaluation model effectively assesses risks and provides preventive measures with potential practical applications. Future research can further refine and apply this model to benefit enterprises and financial institutions in the NEV industry.

Objective To evaluate the clinical application value of the compression and storage algorithm of histopathological images based on matrix computing, and to seek the best image compression ratio. Methods Two classical matrix algorithms, principal component analysis (PCA) and singular value decomposition (SVD), were used to compress and reconstruct the immunohistochemical images and HE staining images of low, medium and high differentiated cervical cancer tissues. The peak signal-to-noise ratio(PSNR) and structural similarity (SSIM) were used to analyze and evaluate the quality of image reconstruction. Results When the compression ratio of PCA reconstruction image was 10.18 (53 principal components were retained), the mean PSNR of immunohistochemical images of low, medium and high differentiated cervical cancer tissues were 43.84±0.43, 43.27±0.25 and 43.71±0.49, respectively, and the SSIM were 0.964±0.004, 0.963±0.006 and 0.965±0.005, respectively. Meanwhile, the mean PSNR of HE staining images of low, medium and high differentiated cervical cancer tissues were 43.41±0.78, 42.95±1.03 and 43.52±0.69, respectively, and the SSIM were 0.953±0.010, 0.949±0.015 and 0.960±0.007, respectively. When the compression ratio of SVD reconstruction image was 10.00(128 singular values were retained), the mean PSNR of immunohistochemical images of low, medium and high differentiated cervical cancer tissues were 39.89±1.69, 38.20±2.19 and 40.90±0.50, respectively, and the SSIM were 0.949±0.006, 0.938±0.011 and 0.955±0.004, respectively. Meanwhile, the mean PSNR of HE staining images of low, medium and high differentiated cervical cancer tissues were 40.31±0.98, 39.46±1.59 and 40.77±1.67, respectively, and the SSIM were 0.965±0.006, 0.943±0.010 and 0.969±0.005, respectively. Conclusions PCA and SVD can compress and store histopathological images and obtain better image quality, which provides a solution to the problem of hospital image storage.

In the context of intercultural communication, as a traditional Chinese festival. The Spring Festival (also called Chinese New Year)has caused widespread dissemination overseas. The article takes Chinese mainstream media CGTN’s Chinese New Year related reports released on Youtube platform as research samples, and takes the period of Chinese New Year of the Rabbit in 2023 as the time period for the study. Starting from the video content released by CGTN, the article explores the Chinese image and Chinese symbols shaped by it. And with the support of Frame Theory, the study analyzes the reporting framework from two levels of textual content and value orientation, and further to explore the communication dilemma of Chinese image in the intercultural communication context.

Cage aquaculture is an important strategic direction for marine aquaculture. Aiming at the problems that the existing offshore cages are difficult to adjust the breeding areas adaptively to optimize the ecological environment and the difficulty in transportation due to their large size， a novel primary and secondary embedded deployable offshore cage is proposed which the over-constrained spatial mechanisms and planar compliant mechanisms are respectively adopted as the primary and secondary cages. A closed-loop cable-driven module is designed to deploy the cage through the pull and release of the cable. Then， the evolution of the dimension constraint types of the threefold-symmetric Bricard mechanism which forms the primary cage mechanism is investigated. The geometric invariant characteristics that three symmetric planes intersecting at a determined line are revealed so that the cage driven mechanism with the symmetrically plane intersecting line as the axis of mechanism folding is constructed. Further， by establishing the kinematics equation of the primary cage mechanism， the relationship between the driven angle and corresponding open state of the cage can be derived from geometric projection on the symmetric planes. The novel primary and secondary embedded deployable cage mechanism with large deployable ratio can provide new thread for the design of offshore cages.

In order to analyze the hot frontier of academic entrepreneurship and study the influencing factors of academic entrepreneurship, By using citespace V information visualization software and content analysis, 32 papers in CNKI (China National Knowledge Infrastructure) database are retrieved which are indexed by CSSCI (Chinese Social Sciences Citation Index), and 66 papers are retrieved in Web of Science database which are indexed by SSCI (Social Sciences Citation Index); the Chinese and international sample papers were compared and analyzed, and a comparative analysis between Chinese and international papers was made. The results show that the influencing factors of academic entrepreneurship are divided into personal, environmental, and organizational factors. There are many researches on personal factors in China and external factors such as environment, organization, and system in international countries. Chinese research tends to the macrolevel, while international research pays more attention to the microlevel. The research frontier at home and abroad is the research of academic entrepreneurial process at microlevel. Finally, some suggestions are given to academic entrepreneurship: academic exchanges should be strengthened, more support platforms should be set up in university institutions, and the state should introduce incentive policies to enhance the strength and level of academic entrepreneurship.

Environmental logistics has become the irreversible trend of logistics development in the future, and it is also an inevitable choice to promote the transformation of China's modern logistics industry. Regions that want to develop environmental logistics must scientifically evaluate the current status of environmental logistics development. This paper builds a regional environmental logistics evaluation system, horizontally compares the data of Hebei Province and 13 other provinces in 2017, and longitudinal evaluation of data from 2013 to 2017 in Hebei Province, and obtains the ranking of the development status of environmental logistics in Hebei Province and its development trend in the past five years. Based on the evaluation results, countermeasures and suggestions are proposed for improving the level of environmental logistics in Hebei Province, including increasing the comprehensive utilization rate of waste; reinforcing the investment in related fixed assets; reducing the energy consumption of the logistics industry; improving the operating mileage of public railways, and increasing the freight volume.
