Theoretical Challenges, Practical Contradictions, and Collaborative Governance in the Modernization Transformation of Small-scale Peasant Production
摘要: Small-scale peasant production is the fundamental mode of agriculture in China, and its modernization transformation faces significant theoretical and practical challenges. Theoretically, classical agricultural modernization theories are inadequately tailored to the specific national condition of small-scale peasant production in China. The coexistence of multiple conflicting paradigms has resulted in systemic fragmentation, and there remains a deficiency in comprehensive investigations into the subjectivity of small-scale peasants. At the practical level, prominent contradictions include imbalances in factor supply, outdated business models, and the limited capabilities of main bodies. To address these issues, it is essential to establish a multi-stakeholder collaborative governance framework involving the "government, market, social organizations, and small-scale peasants". This framework should enhance government guidance, fully leverage the role of market allocation, activate the bridging functions of social organizations, and prioritize the cultivation of intrinsic motivation among small-scale peasants. Through the coordinated efforts of these multiple entities, barriers to transformation can be overcome, thereby facilitating the integration of small-scale peasant production with modern agricultural practices.

3D Modeling and Quantitative Analysis of Remediation Engineering for Coal Field Fire Zones by Integrating Multi-Source Data
摘要: This research focuses on a steeply inclined coal seam fire zone in Xinjiang, proposing a novel 3D geological modeling and analysis approach that integrates multi-source data, including drilling and geothermal monitoring. Utilizing a software platform, a high-precision 3D model integrating topography, coal seams, fire zone boundaries, and the temperature field was constructed. This model enables the 3D visualization and precise delineation of the combustion extent and temperature distribution within the fire zone. Building upon this foundation, a new quantitative calculation method was developed based on the 3D block model. This method facilitates the classification of fire zone reserves, demarcation of remediation areas, and quantification of water injection volume, loess coverage volume, as well as excavation and leveling quantities. The results demonstrate that, compared to traditional two-dimensional methods, the proposed 3D quantitative analysis approach enhances the accuracy of remediation engineering quantity calculations by over 20%, significantly reducing project uncertainty. This research provides a robust technical framework for transitioning coal field fire zone remediation from "empirical judgment" to "3D precise quantification" in decision-making, holding significant theoretical importance and substantial engineering application value.

Preservation Effect of Ginger Essential Oil Solution on Pre-prepared Lentinus edodes Dishes
摘要: [Objectives] To introduce a ginger essential oil solution possessing a dual "antibacterial-antioxidant" protective effect, and investigate its preservation effect on fresh-cut pre-prepared Lentinus edodes. [Methods] Single-factor experiments combined with response surface methodology were conducted to screen the optimal concentration of ginger essential oil, using sensory score, total phenol content, and polyphenol oxidase (PPO) activity as evaluation indicators. A verification test was carried out to compare the preservation effects of the optimal concentration treatment group and the control group under the storage condition at 25 ℃. [Results] Response surface analysis determined that the optimal concentration of ginger essential oil was 0.3%. The verification test showed that under the storage condition at 25 ℃, the 0.3% ginger essential oil treatment group extended the shelf life by 4 d compared with the control group. Compared with the control group, the treatment group exhibited a 23.4% increase in total phenol content and a 59.0% reduction in PPO activity, and its sensory quality was significantly superior. [Conclusions] The 0.3% ginger essential oil solution effectively maintained the sensory quality of fresh-cut L. edodes, increased the content of endogenous antioxidants, and inhibited the activity of browning-related enzymes, thereby extending the shelf life by 4 d. This study provides a new method for the green preservation of edible fungi.

Research on the Enhancement of Job Competence of Medical Functional Experiment Technicians in the Context of Digital Transformation
摘要: [Objectives] To establish a competency assessment framework for medical functional experiment technicians amid digital transformation, pinpoint specific weaknesses, and formulate systematic enhancement measures. [Methods] A mixed-methods approach combining literature review, structured questionnaires, and semi-structured interviews was adopted. A survey was conducted among 39 technicians at the School of Basic Medicine, Hubei University of Medicine. A two-dimensional, six-indicator competency model was constructed and subjected to further analysis. [Results] The scores of traditional experimental competence increased progressively with professional title level, with the senior group scoring significantly higher than the junior group (P<0.05). In terms of digital literacy, however, the intermediate and junior groups performed significantly better than the senior group (P<0.05). The major weaknesses identified included: low proficiency in digital tool application (only 32.3% reported being proficient), weak awareness of data security (61.3% lacked standardized practices), and insufficient innovation in digital teaching (fewer than 25% had participated in blended teaching design). In particular, digital literacy was significantly lower among staff with higher professional titles and those of older age. [Conclusions] Digital transformation imposes a dual requirement on experimental technicians: they must possess both solid traditional competencies and strong digital literacy. To address this, efforts should be synergistically advanced from three aspects, namely, individual self-directed learning, a tiered training system, and institutional incentives. Particular emphasis should be placed on enhancing digital literacy training for older staff, so as to systematically improve overall job competency.
