获取高分辨率的农作物种植结构图对保障粮食安全和优化农业政策具有重要意义。但在实际应用中,利用多源遥感数据提取作物种植结构时,面临光谱分辨率差异导致的星机协同性难题,以及卫星影像中混合像元对面积信息提取的干扰。本研究探索... 获取高分辨率的农作物种植结构图对保障粮食安全和优化农业政策具有重要意义。但在实际应用中,利用多源遥感数据提取作物种植结构时,面临光谱分辨率差异导致的星机协同性难题,以及卫星影像中混合像元对面积信息提取的干扰。本研究探索了基于无人机多光谱数据和Planet Scope卫星遥感数据提取作物种植结构的方法,以宝鸡峡灌区的小麦、玉米、葡萄和猕猴桃为研究对象,开展空间分布与面积信息提取研究。本研究首先通过计算卫星与无人机像元的波段反射率比值,校正卫星光谱波段,从而精细化作物分布的提取阈值;其次通过机器学习算法对无人机影像进行分类,获取卫星混合像元中的作物纯净面积比例;最后基于遗传算法优化的随机森林模型,构建混合像元中植被指数与面积权重的量化关系。结果表明,多源遥感方法获取的作物分布图(6 m分辨率)中,重合像元数量较仅使用卫星影像下降35.75%,这一结果说明多源遥感数据可有效缓解“异物同谱”问题。其中,小麦和玉米的面积信息提取效果最优,相较于单时相卫星影像,典型区域中小麦和玉米的面积相对误差率分别降低19.17%和38.49%;整体来看,小麦、玉米、葡萄、猕猴桃的面积相对误差率分别为-4.83%、0.51%、6.55%、8.79%。本研究提出的从无人机到卫星跨尺度协同观测方法,为灌区主要作物种植管理措施制定提供了技术与数据保障,为作物空间分布与面积信息提取从田块尺度向灌区尺度扩展提供新思路,有助于促进灌区的精准农业技术发展。 展开更多

Purpose:To examine variations in Chinese nurses’Actual Scope of Practice(ASCOP)by educational qualifications and professional titles,and to identify regulatory gaps in competency-based role assignments within China’s evolving healthcare system.Method:A nationwide cross-sectional study using the validated Chinese Nurses’ASCOP Questionnaire is used.Data from 1,540 nurses were analyzed through descriptive statistics,independent t-tests,one-way ANOVA,and Bonferroni correction.ASCOP scores(1–5 scale)were compared across education levels(diploma,bachelor’s,postgraduate)and titles(junior/senior).Results:The overall ASCOP score was 3.95,with significant disparities in high-complexity tasks:postgraduate nurses(4.25)and senior nurses outperformed diploma holders(3.71)and juniors(p<0.01).Low-complexity tasks showed no educational differences(p>0.05),though bachelor’s or postgraduate nurses reported higher frequencies(4.12 vs.3.89).Alarmingly,37.6%of junior nurses routinely performed high-risk procedures beyond their competency.Conclusion:A systemic mismatch exists between nurses’qualifications and assigned responsibilities,reflecting inadequate regulatory oversight.To address this,this study recommends:(1)competency-based tiered authorization systems,(2)legal framework updates aligning with China’s healthcare reforms,and(3)dynamic monitoring mechanisms.These measures could standardize practice boundaries,mitigate occupational risks,and optimize nursing workforce utilization,particularly in resource-constrained settings. 展开更多

The understanding of the scope of protection for the right to health should not be limited to fragmented descriptions in departmental laws,such as those focusing on rights,interests,or legal benefits.Instead,it should be analyzed holistically within the constitutional framework of fundamental rights.From the perspective of defense right function,the right to health addresses physiological harm that progresses through stages of“risk-danger-infringement,”psychological harm that targets inner distress,and minor harm arising from challenges in social adaptation,to clarify the negative defensive obligations of the state to prevent health-related harm.From the perspectives of the beneficiary right function and the objective value order function,the right to health requires a minimum level of constitutional protection and delineating the positive obligations of the state to ensure it through the fulfillment of basic obligations in healthcare and health promotion. 展开更多

AIM: To compare dgid proctoscope and flexible endoscope for elastic band ligation of internal hemorrhoids. METHODS: Patients between 18 and 80 years old, with chronic complaints (blood loss, pain, itching or prolapse) of internal hemorrhoids of grade 1-91, were randomized to elastic band ligation by rigid proctoscope or flexible endoscope (preloaded with 7 bands). Patients were retreated every 6 wk until the cessation of complaints. Evaluation by three-dimensional anal endosonography was performed. RESULTS: Forty-one patients were included (median age 52.0, range 27-79 years, 20 men). Nineteen patients were treated with a rigid proctoscope and twenty two with a flexible endoscope. Twenty-nine patients had grade I hemorrhoids, 9 patients had grade 11 hemorrhoids and 3 patients had grade 91 hemorrhoids. All patients needed a minimum of 1 treatment and a maximum of 3 treatments. A median of 4.0 bands was used in the rigid proctoscope group and a median of 6.0 bands was used in the flexible endoscope group (P 〈 0.05). Pain after ligation tended to be more frequent in patients treated with the flexible endoscope (first treatment: 3 vs 20 patients, P 〈 0.05). Three- dimensional endosonography showed no sphincter defects or alterations in submucosal thickness. CONCLUSION: Both techniques are easy to perform, well tolerated and have a good and fast effect. It is easier to perform more ligations with the flexible endoscope. Additional advantages of the flexible scope are the maneuverability and photographic documentation. However, treatment with the flexible endoscope might be more painful and is more expensive. 展开更多

Advances in endoscopic and surgical techniques have increased the frequency and complexity of these procedures and associated complications such as gastrointestinal perforation. With the advancements in the field of gastroenterology, the promising use of an over the scope clips(OTSC) has fulfilled the unmet need for a reliable endoscopic devise in approximation of gastrointestinal perforation. This novel approach has raised the level of confidence in endoscopist in dealing with this serious complication during endoscopy. Here we have shared our experience with OTSC to evaluate its efficacy and safety in managing iatrogenic gastrointestinal perforations during endoscopy. 展开更多

Gastrointestinal (GI) defects such as fistulas and leaks can be potentially closed endoscopically using hemo-clips and loops. However, hemoclips may not allow for closure of large defects and they do not exert enough tensile force to keep fibrotic defects larger than 5 mm approximated. Herein we present a case of successful endoscopic closure of a gastrocolic fistula in a severely malnourished patient with complex post-surgical upper GI anatomy. We strongly believe that this device is a major breakthrough for the management of various types of discontinuity defects or fistulas. In addition, we show the usefulness of placing a direct jejunostomy using the double balloon enteroscopy (DBE) technique during the same procedure. The concept of providing direct jejunal feedings while allowing for upper gas-trointestinal bowel rest to promote the healing of the minimally invasive endoscopic operation is novel. Thus, our case is unique and exemplifies the utility of mini-mally invasive endoscopic endoluminal surgery. 展开更多

Percutaneous endoscopic gastrostomy(PEG) is a common practice for long-term nutrition of patients who are unable to take oral food. We report of an 85-year old man with a history of recurrent larynx carcinoma and hemicolectomy many years ago due to unknown reason. Laryngectomy was indicated. Preoperatively a PEG was inserted endoscopically after an abdominal ultrasonography without abnormal findings. Few months after PEG insertion, the patient was evaluated for diarrhea and insufficient feeding without signs of infection or peritonism. An upper endoscopy and computed tomography scan confirmed a buried bumper syndrome with migration of the PEG tube into the colon as a rare complication. He underwent successful colonoscopic removal of the internal bumper and closure of the colonic orifice of the fistula with the over-the-scope-clip system(OTSC). OTSC is an endoscopic device for treatment of bleeding, perforation, leak and fistula in the gastrointestinal tract. To the best of our knowledge, this is the first report of the use of OTSC for colonoscopic closure of a gastrocolocutaneous fistula due to a buried bumper syndrome with transcolonic PEG tube migration. 展开更多
