Abstract:
旅游业作为一个综合性产业,具有产业关联度高、波及效应明显的典型特征。基于对期刊网相关文献的遴选,文章从旅游产业内部子产业的依存关系及其与国民经济其他产业之间的关联程度等方面对国内旅游产业关联与波及效应的相关研究进行了系统回顾,并提出了现有研究存在的不足,以期为优化产业结构、促进国民经济发展提供有益的参考。
As a comprehensive industry, tourism is highly associated with other industries and is characte-rized with clear ripple effect. According to related literatures on CNKI, the paper makes a syste-matic retrospect of the relevant study at home on the association and ripple effect of tourism from the following aspects: dependency of sub-sectors within tourism, the degree of association between tourism and other sectors of the national economy. Defects existing in the present studies are also put forward in the hope of providing some useful reference for optimizing industrial structure and promoting economic development.
青岛市旅游地域系统演化驱动因子及其作用强度分析
Analysis on Factors and Their Effects on Driving Evolution of Qingdao Regional Tourism System
 [PDF]


Geographical Science Research (GSER) , 2015, DOI: 10.12677/GSER.2015.43015
Abstract:
本文立足旅游地域系统运行状态,建立了包括自然生态环境、社会经济、区位、旅游本底条件、政府旅游业宏观调控水平等诸多层面因素的系统演化驱动因子指标体系,借助灰色关联分析、协整检验与估计等定量研究方法,分析青岛市旅游地域系统演化的关键驱动因子及其作用强度。结果表明,社会经济基础、旅游区位、旅游本底条件及政府对旅游业宏观调控水平对青岛市旅游地域系统发展起正向作用;旅游开发及旅游经济发展通过增大生态环境负面影响,间接对系统发展起负向作用。旅游经济与生态环境协调发展是旅游地域系统可持续发展的关键。
Based on the status of regional tourism system, this paper established complex index system in-cluding eco-environment, social economy, tourism location, tourism development conditions and the efficiency of government macro-management on tourism, and analyzed the key factors and their effects on driving evolution of Qingdao regional tourism system with Gray Relational Analysis and Co Integration Analysis. The data show that social economy, tourism location, tourism development conditions and the efficiency of government macro-management on tourism play a positive role in Qingdao regional tourism system development, while the negative effect of eco- environment caused by tourism development and tourism economy plays a negative role in the system development indirectly. Coordinative development of tourism economy and ecological environment is the key to sustainable development of regional tourism system.
青岛市旅游地域系统可持续发展动态仿真与评价
Dynamic Simulation and Analysis on Sustainable Development of Qingdao Regional Tourism System
 [PDF]


Geographical Science Research (GSER) , 2015, DOI: 10.12677/GSER.2015.43017
Abstract:
旅游经济与生态环境协调发展是旅游地域系统可持续发展的关键。本文以青岛市旅游地域系统为研究对象,运用系统动力学方法,仿真旅游地域系统动态变化趋势、调控系统发展,探索青岛市旅游地域系统可持续发展模式。主要结论:第一,青岛市旅游地域系统存在低效发展问题,具体表现为旅游产业粗放型经济增长和旅游地域空间低效率扩张;第二,以目前自然演变过程,青岛市旅游地域系统状态呈阶段性下降态势,须在2015年系统状态进入第二次下降趋势之前对其进行调控、优化;第三,仿真结果比较分析表明,适度加大旅游资源开发、旅游基础设施建设力度,增强政府对旅游业宏观调控作用,加大生态建设与环境保护力度,走集约型增长道路,是青岛市旅游地域系统可持续发展的选择。
Coordinative development of tourism economy and ecological environment is the key point to sustainable development of regional tourism system. The paper takes the regional tourism system of Qingdao as the study area, simulates and regulates its development trend to explore the sus-tainable development pattern of the system, by the method of System Dynamics. The main conclu-sions are as follows: First, the regional tourism system of Qingdao is in somewhat inefficient de-velopment, specially the extensive growth of tourism economy and the inefficient expansion of tourism geographic space. Second, according to the natural evolution, the system will present a declining trend by phases, and regulations must be done before it enters into the second declining phase in 2015. Third, the comparative analysis on simulation results shows that a moderate in-crease of government’s macro-control on tourism, tourism resources development and tourism infrastructure construction, resulting in the intensive growth of tourism economy, is the way to realize the sustainable development of regional tourism system of Qingdao.
髌骨脱位诊断方法综述
Review of Diagnostic Methods for Patella Dislocation
 [PDF]

Medical Diagnosis (MD) , 2016, DOI: 10.12677/MD.2016.63013
Abstract: 髌骨损伤容易引起膝关节功能性障碍,常出现于年轻及运动较多、量较大的人群,而髌骨脱位则是其最常见的临床表现。目前来讲,在髌骨损伤诊断中,CT扫描图像有着重要的临床价值,通过CT扫描图像测量获得的与髌骨、股骨相关的数据,如Q角、髌骨倾斜角、外侧髌骨移位值、TT-TG等数据为主治医师的诊断提供了重要的数据支撑,在一定程度上提高了主治医师对髌骨损伤类型诊断的正确率。
Patella injury which often occurs in the young people with more exercise can cause functional disorder of the knee joint, and patellar dislocation is one of the most common clinical manifestat- tions. At present, CT image has the important value in the patella injury clinical diagnosis, and the date related to patella and femur obtained by CT such as Q angle, patella tilt angle, lateral patella displacement value and TT-TG can provide the important data support for the physician’s diagnosis, and also improve the diagnostic accuracy of the patella injury on some level.

无形资产审计的新领域:企业核心竞争力审计

财会月刊 , 2005,
Abstract:   有学者认为,企业核心竞争力实质上是企业多种无形资产综合作用产生的合力,是建立在企业核心资源基础上的智力、技术、产品、管理、文化等综合优势在市场上的反映,是企业的一组独特技能和知识的集合。这种能力可以使企业长期保持其竞争优势,因而是一种影响企业可持续发展的重要资源。本文就企业核心竞争力审计相关问题作一探讨。  一、企业核心竞争力审计研究框架的初步构想  企业核心竞争力是由无形资产构成的,无形资产是核心竞争力的构成要素,是核心竞争力的载体。拥有一定数量和质量的无形资产是培育企业核心竞争力的必要条件。笔者拟将企业核心竞争力审计列入企业无形资产审计体系中,并对其审计框架作初步构想。

复水时间对干制铁核桃雄花营养品质及抗氧化活性的影响

- , 2017, DOI: 10.13982/j.mfst.1673-9078.2017.4.038
Abstract: 本文研究了复水时间对干制核桃雄花主要营养成分、矿质元素、氨基酸、抗氧化活性物质含量及抗氧化活性的影响。结果表明:干制核桃雄花复水时间应控制在10 min时能较好地维持其较高的营养品质和抗氧化活性;短时间(10 min)的复水对干制核桃雄花脂肪、淀粉及部分氨基酸(Glu、Tyr、Lyr和Pro)等大分子化合物含量影响较小;随复水时间延长,干制核桃雄花中各种常规营养成分,除钙和镁元素外的7种矿质元素,17种氨基酸以及抗氧化活性物质的含量均呈不同程度的下降趋势,且下降速率增大。从营养品质及抗氧化活性的保持程度来看干制核桃雄花的最佳复水时间为10 min。该研究为科学利用资源丰富的核桃雄花提供技术和理论依据。
The effects of rehydration time on the nutritional quality of dried male walnut flowers were studied by analyzing the contents of primary nutrients, mineral elements, amino acids, and antioxidant substances, as well as the antioxidant activity. The results showed that the nutritional quality and antioxidant activity of dried male walnut flowers could be well maintained when the rehydration time was limited to 10 min. A short rehydration time (10 min) had a slight influence on the contents of macromolecular compounds, such as fat, starch, and some amino acids (glutamate, tyrosine, lysine, and proline). With prolonged rehydration time, the contents of primary nutrients, seven mineral elements (but not calcium or magnesium), 17 amino acids, and antioxidant active substances decreased by various degrees. The longer the rehydration time, the greater the decline observed. In terms of maintaining the nutritional quality and antioxidant activity, 10 min was the optimum time for the rehydration of dried walnut flowers. These results provide a technical and theoretical basis for utilizing abundant male walnut flowers scientifically.
