The impact of population change on social-ecological systems’ vulnerability: A case of the Qinling-Daba Mountains of Southern Shaanxi in China

Human activities have exacerbated the contradiction between ecosystem functionality and social-economic growth. Understanding and managing social-ecological systems' changes under the dual drivers of intensive human activities and rapid global environmental changes are crucial for achieving coordinated and sustainable development. While the vulnerability framework provides a new perspective for human-environment relationship studies, limited research has focused on the impact mechanisms of population change on social-ecological systems' vulnerability (SESV). Therefore, this study selects the Qinling-Daba Mountains of Southern Shaanxi in China (QMSSC), one of the areas with the most prominent human-environment contradictions in China, as a case study. Using the Vulnerability Scoping Diagram (VSD) assessment framework and the Spatially Explicit Resilience-Vulnerability (SERV) model, we divide SESV into three dimensions: exposure, sensitivity, and adaptive capacity. We select indicators, calculate weights, and quantitatively assess the spatiotemporal distribution characteristics, evolution trends, and spatial correlation features of SESV in the QMSSC from 2000 to 2020. Furthermore, we reveal the impact mechanisms of population change on SESV. The results indicate that the impact of population outflow on SESV depends on the spatiotemporal distribution of SESV. Gender ratio's impact on SESV is closely linked to land use and economic development. The proportion of elderly population affects SESV through adaptive capacity. In other words, population change often indirectly drives SESV by affecting different dimensions or elements of SESV. This necessitates policymakers to deploy population strategies across dimensions and elements. This study aims to provide reference for population development policies and spatial governance directions in globally underdeveloped mountainous regions through a typical case analysis of China's mountainous areas.

How to Use Evidence Rules Reasonably to Resolve Land Disputes: Analysis of Typical Land Dispute Cases from China

Impact of Enterprise Digital Transformation on the Efficiency of Total Factor Energy Utilization

With the advent of the information age and the rapid progress of technology, it has become inevitable for enterprises to move towards digital transformation. Energy is one of the most vital material bases for national economic and social development, which plays a vital role in national economic growth. How to use energy efficiently has been the core factor to measure the sustainable development potential of an enterprise. Based on the data of listed companies in China, this paper empirically analyzes the impact of enterprise informatization on energy efficiency from different perspectives. Studies have shown that the degree of enterprise informatization has a direct relationship with its energy efficiency. At present, the overall informatization of enterprises in various regions of China is low. However, with the continuous popularization of digital technology and applications, it has a certain inhibitory effect on enterprise energy consumption, with the effect becoming more and more apparent. Especially during the digital transformation, the role of state-owned enterprises in promoting total factor energy consumption has been more significant. Therefore, from the perspective of digital transformation, it is of great significance to study the energy efficiency of state-owned enterprises. This research explores the significant differences in energy efficiency among various industries, and the adoption of digital transformation strategies will help narrow these differences and further promote energy efficiency improvement across the industry. In addition, through the analysis of typical cases, this topic reveals the main problems faced by enterprises in the process of digital transformation and their causes, which puts forward corresponding countermeasures and suggestions. This study can provide a solid theoretical basis for the positive role played by Chinese enterprises and related departments during the digital transformation.

Can Creating an Agro-Product Regional Public Brand Improve the Ability of Farmers to Sustainably Increase Their Revenue?

Through the analysis of various typical cases, this study examines whether the establishment of an agro-product regional public brand (ARPB) can effectively boost the revenue of farmers and increase their share in the supply chain. The findings suggest that an early-stage ARPB can command a price premium for products, yet its overall contribution to farmers’ revenue remains limited due to scale constraints. The premium ability of an ARPB is influenced by product characteristics and sales strategies, underscoring the need to enhance control over terminal sales. Although the revenue of all operators in an ARPB supply chain shows an increase compared to that of a non-ARPB supply chain, the ratios of revenue allocated to farmers diminish. The Shapley value method was utilized to optimize the revenue-sharing in the supply chain, indicating a need to increase the share of revenue for farmers. This optimization necessitates the formation of a community of interests between farmers, processing enterprises, and sellers to facilitate the upstream movement of brand premiums. Furthermore, enhancing the government’s mediation and regulatory functions can provide farmers with more opportunities to partake in brand benefits.

Discussion on "Five zang-organs all can lead to low back pain, not only the kidney".

Low back pain (LBP) is the common disease in the department of acupuncture and moxibustion in hospital and is treated basically in terms of kidney deficiency. Through clinical observation and in association with classic literature, the authors proposes that the five zang-organs all can lead to LBP relevant to internal injury. Based on the analysis of typical cases, the authors expounds the nature of pain caused by each zang-organ and clarified the keys of the differentiation. LBP related to the liver is manifested mainly as lumbar soreness and distending pain, accompanied by the limited forward and backward extension of the lumbar vertebra. When the dysfunction of the heart and lung are involved, the hollow pain is dominant, combined with the weakness and emptiness feeling in the lumbar region. When LBP is caused by the dysfunction of the spleen, muscular pain is the chief complaint, combined with heaviness and soreness in the local, and the stiffness on palpation. When rooted at the kidney, LBP is manifested chiefly by dull pain, with deep location of illness, mostly around the lumbar sacral region.

A Comparative Study on the Distribution Models of Incident Solar Energy in Buildings with Glazing Facades

The accurate distribution of solar energy on indoor walls is the basis of simulating the indoor thermal environment, and its specific distribution changes all the time due to the influence of solar azimuth and altitude angle. By analyzing the assumptions of each model, the existing solar energy distribution models are eight kinds in all and are divided into three categories. The solar radiation models in TRNSYS, EnergyPlus, and Airpak software all use the absorption-weighted area ratio method, which assumes that a single interior surface is a whole, but the detailed assumptions of the models used in the three software are different. In the Radiosity-irradiation method, the indoor surfaces are discretized into small surfaces for calculation. The calculation accuracy of solar radiation distribution indoors can be controlled by the number of discrete small surfaces. The Radiosity-irradiation method is implemented by using Matlab software programming in this paper. Through the numerical calculation and analysis of typical cases, the solar distribution results of the absorption-weighted area ratio method and the Radiosity-irradiation method all show the asymmetry. The asymmetrical ratio of direct solar radiation varies during the time between 7.96–9.89, and the minimum turns up at 11:30 in the summer solstice. The asymmetrical ratio of diffuse solar radiation is 3.23 constantly. The asymmetrical ratio of total solar energy is mainly influenced by the direct and diffuse solar feat gain and its value changes in the range from 3.4 to 4.45 in the summer solstice. Calculation comparison and error analysis on the solar radiation models used in TRNSYS, EnergyPlus, and Airpak software are conducted. There are significant errors in the simulation results of all three software. TRNSYS has the highest error among the three software as its results do not change over time. For EnergyPlus, the distribution ratio of floor 1 is too large. Airpak has the smallest error, but the solar radiation distribution ratios of the indoor surfaces near the south glazing facade are underrated, especially the indoor surfaces that have not been exposed to direct solar radiation.

Risk Assessment of Compound Dynamic Disaster Based on AHP-EWM

The coal mine in deep mining can easily form a compound dynamic disaster with the characteristics of rock burst and gas outburst. In this paper, the analytic hierarchy process (AHP) and the entropy weight method (EWM) are combined, and the fuzzy comprehensive evaluation (FCE) secondary evaluation model of compound dynamic disaster is proposed to evaluate the risk of compound dynamic disaster, which avoids the problems of the imperfect evaluation index system and strong subjectivity of index weight. Based on the statistical analysis of typical compound dynamic disaster cases in China, three first-level indicators were established, and sixteen second-level indicators were developed. The verification results show that the accuracy and weight are better than the traditional evaluation methods. Combined with geological and mining data, the compound dynamic disaster risk assessment was carried out on the second mining area of mine B, in the Pingdingshan mining area, and the result was grade II (weak risk). Corresponding prevention measures and parameters were implemented, and no compound dynamic disaster occurred during the working face excavation.

Risk Analysis of Airplane Upsets in Flight: An Integrated System Framework and Analysis Methodology

Generally, airplane upsets in flight are considered a precursor to loss of control in flight (LOC-I) accidents, and unfortunately LOC-I is classified as the leading cause of fatal accidents. To further explore the risk factors, causal relationships, and coupling mechanism of airplane upsets, this study proposed a risk analysis model integrating the Interpretative Structural Modeling (ISM) and Bayesian Network (BN). Seventeen key risk factors leading to airplane upsets were identified through the analysis of typical accident cases and the literature. The ISM approach was used to construct the multi-level interpretative structural model of airplane upsets, which could reveal the causal relationship among various risk factors and risk propagation paths. Then, taking 286 accident/incident investigation data as training samples, a data-driven BN model was established using machine learning for dependency intensity assessment and inference analysis. The results reveal that the interaction among risk factors of fatal accidents caused by airplane upsets is more significant than that of non-fatal accidents/incidents. Risk factors such as pilot-induced oscillations/airplane-pilot coupling and non-adherence to Standard Operating Procedures (SOPs)/neglect of cross-validation have a significant effect on airplane upsets in flight among seventeen risk factors. Moreover, this study also identifies the most likely set of risk factors that lead to fatal accidents caused by airplane upsets. The research results have an important theoretical significance and application value for preventing airplane upsets risk.

Scenario derivation and consequence evaluation of dust explosion accident based on dynamic Bayesian network

In order to clarify the correlation between the evolution path of dust explosion accidents and emergency decision-making, and to accurately predict the disaster damage levels of various disaster bearing bodies. This paper extracts 56 key scenario elements from four aspects, namely state, answer, goal and environment, based on the analysis of typical dust explosion accident cases. At the same time, a general scenario evolution path of dust explosion accident is constructed. Using fuzzy number set theory and dynamic Bayes joint probability model, the accurate solution of scenario state probability was realized. With the help of accident cases and dynamic Bayes approach, the dust explosion consequence prediction index system and evaluation criteria were constructed, covering factors such as dust explosion intensity, casualties, direct economic losses, equipment damage, building damage, environmental damage and other factors. A polyethylene wax dust explosion accident in a city of China was used to verify the dust explosion accident scenario evolution model and consequences prediction model. The predicted results were in good agreement with the actual damage of various carriers of the accident, which indicated that the model could be used for dust explosion accident prediction and disaster loss prediction. The research results provided reference and technical support for the prediction of dust explosion accident evolution direction, emergency aid measures decision and deployment, disaster damage prediction and evaluation.

Analysis of Typical Faults and Defects and Testing Methods of Complete Set of Turns-Regulating Arc Suppression Coil

In recent years, many automatic tracking compensation turns-regulating arc suppression coils have been installed in substations to compensate for the increasing capacitive current. However, the frequent occurrence of the fault defects of the arc suppression coil itself has caused a series of new problems, such as causing abnormal bus voltage at the low-voltage side of the substation. Through the analysis and classification of typical faults and defect cases of the complete set of turns-regulating arc suppression coil, it is found that the most vulnerable parts of the device are the on-load tap changer, damping resistance cabinet and control unit. Aiming at the problem that the detection means of the complete arc suppression coil device are insufficient, this paper proposes a new test method, including a compensation characteristic test and relevant accessories test. Based on the new test method, a simulation test platform was built to test 2 sets of turns-regulating arc suppression coil devices. The results show that the new test method has great application value.
