1 Semantic Riverscapes: Perception and evaluation of linear landscapes from oblique imagery using computer vision
مناظر معنایی رودخانه: درک و ارزیابی مناظر خطی از تصاویر مایل با استفاده از بینایی کامپیوتری-2022
Traditional approaches for visual perception and evaluation of river landscapes adopt on-site surveys or as- sessments through photographs. The former is expensive, hindering large-scale analyses, and it is conducted only on street-level or top-down imagery. The latter only reflects the subjective perception and also entails a laborious process. Addressing these challenges, this study proposes an alternative: a novel workflow for visual analysis of urban river landscapes by combining unmanned aerial vehicle (UAV) oblique photography with computer vision (CV) and virtual reality (VR). The approach is demonstrated with an experiment on a section of the Grand Canal in China where UAV oblique panoramic imagery has been processed using semantic segmentation for visual evaluation with an index system we designed. Concurrent surveys, immersive and non-immersive VR, are used to evaluate these photos, with a total of 111 participants expressing their perceptions across multiple dimensions. Then, the relationship between the people’s subjective visual perception and the river landscape environment as seen by computers has been established. The results suggest that using this approach, rivers and surrounding landscapes can be analyzed automatically and efficiently, and the mean pixel accuracy (MPA) of the developed model is 90%, which advances state of the art. The results of this study can benefit urban planners in formulating riverside development policies, analyzing the perception of plans for a future scenario before an area is rede- veloped, and the method can also aid relevant parties in having a macro understanding of the overall situation of the river as a basis for follow-up research. Due to simplicity, accuracy and effectiveness, this workflow is transferable and cost-effective for large-scale investigations of riverscapes and linear heritage. We openly release Semantic Riverscapes—the dataset we collected and processed, bridging another gap in the field.

2 Pork primal cuts recognition method via computer vision
روش تشخیص برش های اولیه گوشت خوک از طریق بینایی کامپیوتری-2022
Pork accounts for more than 33% of global meat consumption and dominates meat consumption in China. With the improvement of peoples quality of life, people pay more and more attention to the quality of pork. There are many factors that affect the quality of pork, and the cutting position of pork is also one of them. The quality of different pork primal cuts varies greatly. Aiming at the difficulty of distinguishing pork primal cuts, this study proposes a computer vision-based method to identify different pork primal cuts, using images of four different pork primal cuts (ham, loin, belly, and neck) as the experimental data, the results show that the method proposed in this paper can identify the original cuts of pork well. It also proves that computer vision technology has the potential to help people identify pork cuts.

5 Nurses perspectives on pain management practices during newborn blood sampling in China
دیدگاه های پرستاران در مورد شیوه های مدیریت درد در طی نمونه گیری خون نوزادان در چین-2021
Introduction: Nurses’ use of evidence-based pain treatments for newborns during needle-related procedures in China was unknown. This study aimed to ascertain knowledge and use of pain management strategies and usefulness of a publicly accessible ’BSweet2Babies’ video, produced in Mandarin, demonstrating the use of breastfeeding, skin-to-skin care (SSC), and sweet solutions during painful procedures. Methods: An online survey was conducted during six nursing conferences in China ascertaining nurses’ previous viewing of the video and knowledge and use of the demonstrated strategies. Results: 221 nurses participated. Only 25 (11.3%) had previously seen the video. Over half knew that breast- feeding (n = 138, 62.4%) and SSC (n = 173, 78.3%) reduced pain, and 89 (40.3%) knew that sucrose reduced pain, but these strategies were infrequently used. Most intended to use the strategies in the future. Discussion: A knowledge-to-action gap for newborn pain management was identified. Future research is needed to improve the implementation of effective pain treatment for newborns.

6 Green supply chain management and clean technology innovation: An empirical analysis of multinational enterprises in China
مدیریت زنجیره تامین سبز و نوآوری در فناوری پاک: تجزیه و تحلیل تجربی شرکت های چند ملیتی در چین-2021
This study identifies the impact of green supply chain management (GSCM) on clean technology innovation (CTI) by enterprises in China as well as compares the effects of forward and backward GSCM and the differences by industry and home country. The effect of CTI on GSCM is tested by 501 samples of mostly multinational enterprises in China from 2014 to 2016. The results indicate that CTI benefits from GSCM, which remains robust to a series of sensitivity test. And different management directions show great differences, where the backward GSCM has a stronger promotion effect on CTI than the forward GSCM. Moreover, light polluting industries and capital-intensive industries have stronger incentives to adopt GSCM than heavy-polluting industries and labour intensive industries. And domestic companies perform better than foreign companies.

7 Integrating corporate website information into qualitative assessment for benchmarking green supply chain management practices for the chemical industry
ادغام اطلاعات وب سایت شرکت ها در ارزیابی کیفی برای محک زدن شیوه های مدیریت زنجیره تامین سبز برای صنایع شیمیایی-2021
The China’s chemical industry has been endeavoring to promote sustainable development through practicing green supply chain management (GSCM). This paper proposes a multi-criteria decision framework with twenty practices to guide companies in the industry to enact GSCM effectively. The exploratory factor analysis (EFA) has been used to cluster the proposed practices. We found five aspects, including economic initiatives, environmental management, eco-design, resource recycling, and stakeholder and employee, constitute the underlying structure of GSCM. A mixed decision tool combining the entropy weight method (EWM) and the analytic hierarchy process (AHP) has been developed and applied to identify key factors. Official website information has been collected and used to analyse the website contents of five benchmarking companies in the China’s chemical industry. The results reveal that the aspects of environmental management, eco-design and resource recycling are the most important GSCM themes. Moreover, the top five practices are top management support, performing life cycle assessment, managing environmental risks, advancing recycling technologies and integrating reverse logistics. Conceptual and practical implications are discussed.

8 Accounting-based downside risk and expected stock returns: Evidence from China
ریسک نزولی مبتنی بر حسابداری و بازده سهام مورد انتظار: شواهدی از چین-2021
We document that earnings downside risk contains information on firms’ future operating performance and is positively associated with expected stock returns in Chinese stock markets, and the return predictability of earning downside risk mainly comes from its accrual downside risk component. The pricing of earnings downside risk is especially evident among firms with more transparent information environment and stronger governance efficacy, such as large firms, non-high-tech firms, old firms, and firms with high analyst coverage. Lastly, we show that aggregated earnings downside risk and its components at the market level are all significantly and positively associated with subsequent stock market returns, which is consistent with the notion that the accounting-based downside risk measures contain information about future macroeconomic conditions.

9 Self-management on heart failure: A meta-analysis
خود مدیریتی در نارسایی قلبی: متاآنالیز-2021
Background and aims: Heart failure (HF) is a severe public health problem all over the World. Selfmanagement is an effective method to progress self-care ability. However, the role of selfmanagement in heart failure has not been thoroughly elucidated.
Methods: The research articles related to heart failure were searched by the PubMed, Embase, Cochrane databases, and China National Knowledge Database on articles published through March 2020. The average 95% of confidence intervals (CIs) were used to calculate using random-effects or fixed-effects. Review Manager (version 5.2) was adopted for meta-analysis, sensitivity analysis, and bias analysis.
Results: Eight (8) eligible studies with 1707 patients with HF were included in this analysis. In the Metaanalysis showed significant differences for Self-management (SM) groups in Dutch Heart Failure Knowledge Scale (DHFK) (MD ¼ 1.36, 95%CI [-0.03, 2.75], P ¼ 0.04; I2 ¼ 83%), in Self-Care of Heart Failure Index (SCHFI) (MD ¼ 5.51, 95%CI [0.62, 10.40], P ¼ 0.03; I2 ¼ 70%), and in Self-Efficacy for Managing Chronic Disease Scale (SEMCDI) (I2 ¼ 47%, Z ¼ 5.43, P of over effect < 0.0001) than control groups. One bias is detected as attrition bias, and another one is reporting bias. Sensitivity analysis satisfied the stability of the results.
Conclusion: Self-management was associated with significant outcomes in patients with HF through knowledge, attitude, and practice (KAP).

10 Assessment of Medical Expenditure for Patients With Breast Cancer in China: Evidence From Current Curative Expenditure by System of Health Accounts 2011
ارزیابی هزینه های پزشکی برای بیماران مبتلا به سرطان پستان در چین: شواهد از هزینه های درمانی فعلی توسط سیستم حساب های بهداشتی 2011-2021
Objectives: The incidence and mortality of breast cancer have been increasing in China and bring heavy economic burdens to patients, families, and society. This study aimed to analyze the structure and influencing factors of inpatient expenditures of patients with breast cancer and put forward suggestions for insurance management.
Methods: A multistage stratified random sampling method was used to investigate 379 medical institutions and 7366 pieces of inpatient records of patients with breast cancer in Dalian in 2018. Under the framework of “System of Health Accounts 2011,” the current curative expenditure (CCE) and its distribution were calculated. The relationships between hospitalization expenditure and factors were analyzed by multiple stepwise regression and structural equation modeling.
Results: The CCE of patients with breast cancer in Dalian in 2018 was U273.38 million, accounting for 10.66% of the total expenditure on cancer. The majority of the CCE flowed to large general hospitals. The CCE was concentrated in patients aged 40 to 69 years (23.46%). The hospitalization expenditure correlated positively with length of stay, surgery, and drug expenses (rs = 0.586-0.754, P,.01) and negatively associated with age (rs = 20.074, P,.01). The length of stay mediated the relationship between surgery and hospitalization expenses for patients with breast cancer. The factors that affected the hospitalization expenditure were the drug expenses, surgery, length of stay, insurance status, and institution level.
Conclusions: The cost control for CCE of breast cancer inpatient treatment is crucial in China. Promoting hierarchical diagnosis and treatment, reducing the length of stay, and improving medical insurance depth would be effective measures to reduce the financial burden of patients.
