    背景:评价临床护理实践教育质量的关键,目标,和可行的指标体系。当前对临床教学的评估通常衡量医院的学习环境,课堂教学,教学能力,或护生的实习质量。因此,临床评估往往不足以提供有针对性的反馈,指导教师发展,或确定临床教师实施变革和改进的具体领域。因此,我们研究的目的是建立一个科学的,系统,并建立临床适用的临床护理实习教学质量评价指标体系,确定各指标的权重,为科学、客观地评价临床护理实习教学质量提供参考依据。
    方法:基于“结构-过程-结果”理论模型,通过文献复习和德尔菲调查,建立临床护理实践教学质量评价指标体系。采用层次分析法(AHP)确定各指标的权重。
    结果:两轮专家调查的有效响应率为100%。专家权威系数分别为0.961和0.975。各级别指标的变异系数范围为0~0.25和0~0.21,肯德尔和谐系数分别为0.209和0.135,差异具有统计学意义(P<0.001)。最终建立的指标体系包括3个一级,10二级,和29个三级指标。根据层次分析法计算的权重,一级指标排名为“过程质量”(39.81%),“结构质量”(36.67%),和“结果质量”(23.52%)。在次要指标中,专家最关注“教学人员”(23.68%),"教学规章制度落实(14.14%),和“教学计划”(13.20%)。三级指标排名前三位的是"师资队伍水平"(12.62%),“教师队伍结构”(11.06%),和“实施教学对象管理制度”(7.54%)。
    结论:构建的临床护理实习教学质量评价指标体系科学可靠,合理的重量。管理者的重点已经从面向结果的方法转向面向过程的方法,更加注重教师队伍建设,教学条例执行情况,提高临床教学质量需要进行教学设计。
    BACKGROUND: The key step in evaluating the quality of clinical nursing practice education lies in establishing a scientific, objective, and feasible index system. Current assessments of clinical teaching typically measure hospital learning environments, classroom teaching, teaching competency, or the internship quality of nursing students. As a result, clinical evaluations are often insufficient to provide focused feedback, guide faculty development, or identify specific areas for clinical teachers to implement change and improvement. Therefore, the purpose of our study was to to construct a scientific, systematic, and clinically applicable evaluation index system of clinical nursing practice teaching quality and determine each indicator\'s weight to provide references for the scientific and objective evaluation of clinical nursing practice teaching quality.
    METHODS: Based on the \"Structure-Process-Outcome\" theoretical model, a literature review and Delphi surveys were conducted to establish the evaluation index system of clinical nursing practice teaching quality. Analytic Hierarchy Process (AHP) was employed to determine the weight of each indicator.
    RESULTS: The effective response rate for the two rounds of expert surveys was 100%. The expert authority coefficients were 0.961 and 0.975, respectively. The coefficient of variation for the indicators at each level ranged from 0 to 0.25 and 0 to 0.21, and the Kendall harmony coefficients were 0.209 and 0.135, respectively, with statistically significant differences (P < 0.001). The final established index system included 3 first-level, 10 second-level, and 29 third-level indicators. According to the weights computed by the AHP, first-level indicators were ranked as \"Process quality\" (39.81%), \"Structure quality\" (36.67%), and \"Outcome quality\" (23.52%). Among the secondary indicators, experts paid the most attention to \"Teaching staff\" (23.68%), \"Implementation of teaching rules and regulations (14.14%), and \"Teaching plans\" (13.20%). The top three third-level indicators were \"Level of teaching staff\" (12.62%), \"Structure of teaching staff\" (11.06%), and \"Implementation of the management system for teaching objects\" (7.54%).
    CONCLUSIONS: The constructed evaluation index system of clinical nursing practice teaching quality is scientific and reliable, with reasonable weight. The managers\' focus has shifted from outcome-oriented to process-oriented approaches, and more focus on teaching team construction, teaching regulations implementation, and teaching design is needed to improve clinical teaching quality.

    The primary goal of national parks is to protect ecological environment, but also with the functions of scientific research, education, and recreation. Aiming for the realization of universal sharing, we used the analytic hierarchy process (AHP) to construct an ecotourism suitability evaluation system by selecting four factors, including landscape resources, ecological environment carrying capacity, recreation utilization capacity and social condition, taking Xiaoxiangling area of Giant Panda National Park and the surrounding communities as an example. We evaluated the ecotourism suitability based on GIS, and conducted a questionnaire survey of tourists, to propose suggestions on the functional zoning in terms of ecotourism suitability and subjective choice preferences of tourists. The results showed that the ecotourism suitability of the evaluation area could be classified into five levels. The most suitable areas were located nearby the natural landscape resources and far away from the core conservation area, and the least suitable areas distributed at the edge of the core conservation area. According to the results of suitability analysis, the evaluation area was divided into suitable development area, moderate development area, and restricted development area. Combined with the tourist preferences, we divided the recreational activities in the evaluation area into seven activities, namely, ecotourism, eco-camping, science education, leisure vacation, agricultural and animal husbandry culture experience, eco-education, and mountain adventure. These findings could help provide suitable services for different tourists and offer reference for the ecotourism developmental planning of the Xiaoxiangling area of the Giant Panda National Park.

    甘薯品种选育始终是一个漫长的过程。在此过程中,杂交后代的筛选以经验判断为主。数据分析和决策疲劳一直困扰着育种者。近年来,低效率的筛选模式已经不能满足甘薯种质创新的要求。因此,有必要构建一种高效的方法来筛选不同用途的种质,用于挖掘精英基因型,并创造专用的甘薯品种。在这篇文章中,基于六个农艺性状构建了多标准决策(MCDM)模型,包括鲜根产量,藤蔓长度,藤蔓直径,分支编号,根数和储存根的空间分布,和五个品质性状,包括干物质含量,可销售的根系产量,根的均匀性,淀粉含量和食用品质评分。其中,采用模糊综合评价法综合颜色感官评分,计算食用品质评分,气味,甜蜜,粘性和纤维味。通过对25种甘薯材料的评估,将MCDM模型与传统筛选方法进行了比较。主观因素对评价结果的干扰明显降低。MCDM模型更全面,在优质甘薯材料的选择上比传统的筛选方法更准确、更快。它可以被编程为与传统的筛选方法相结合地服务于育种者。
    Sweetpotato variety breeding is always a long process. Screening of hybrid offspring is dominated by empirical judgment in this process. Data analysis and decision fatigue have been troubling breeders. In recent years, the low-efficiency screening mode has been unable to meet the requirements of sweetpotato germplasm innovation. Therefore, it is necessary to construct a high-efficiency method that can screen germplasms for different usages, for mining elite genotypes, and to create dedicated sweetpotato varieties. In this article, the multicriteria decision-making (MCDM) model was constructed based on six agronomic traits, including fresh root yield, vine length, vine diameter, branch number, root number and the spatial distribution of storage roots, and five quality traits, including dry matter content, marketable root yield, uniformity of roots, starch content and the edible quality score. Among these, the edible quality score was calculated by using fuzzy comprehensive evaluation to integrate the sensory scores of color, odor, sweetness, stickiness and fibrous taste. The MCDM model was compared with the traditional screening method via an evaluation in 25 sweetpotato materials. The interference of subjective factors on the evaluation results was significantly reduced. The MCDM model is more overall, more accurate and faster than the traditional screening method in the selection of elite sweetpotato materials. It could be programmed to serve the breeders in combination with the traditional screening method.

    Site selection for pistachio orchards is an important issue for sustainable agricultural policies, crop productivity, agricultural planning, and communities. This study aims to investigate suitable places for pistachio in the Mardin Province (SE Turkey) by considering several variables, such as meteorological data, topographic conditions, economic factors, and soil characteristics, using Geographic Information System (GIS) and Multi-Criteria Decision Analysis. Pistachio farmers, expert opinions, and literature data were used to determine the requirements for pistachio cultivation. Four main assessment criteria (thirteen sub-criteria), sixty value ranges, and fourteen exclusion criteria were determined for the pistachio land suitability assessment. The weighting of the evaluation criteria was calculated using the Analytical Hierarchy Process (AHP). Farmers and experts have stated that meteorological factors are more important than soil, topography, and economic factors. All data were transferred to the GIS environment, and a land suitability map was created using the weighted linear combination method. The results show that Mardin province has very suitable lands for pistachio cultivation. The resulting map determined that the 228,891.59 ha area in Mardin province is very suitable for pistachio. To evaluate the accuracy of the land suitability map generated for pistachio, the Receiver Operating Characteristic (ROC) curve was used. The value of the area under the curve (AUC) was calculated to be 0.806, which indicates that the study is consistent. The created suitability map will be an essential data source for developing sustainable agricultural strategies in the Southeastern Anatolia region.
