提起旅游,人们脑海里首先浮现的必然是"阳光与海滩"。土耳其是地中海地区的一个主要国家,在历史、文化、自然风光、美食、民俗等方面都具有巨大潜力,并且土耳其人民也非常热情友善。土耳其拥有21世纪的游客所寻求的异国风情。为使土耳其的这种潜力在继续服务于旅游业的同时保持其延续性,就需要认真的自省与科学的研究和规划。旅游业对于一国的社会福利和经济发展有着举足轻重的影响,但也存在毁灭当地资源的可能。理性运用旅游资产、增加游客数量和提高旅游收入,这些都可以通过有效的旅游规划来实现。在此问题上,中央政府、地方政府和非政府组织在相互协作的框架下各司其职显得至关重要。本文通过揭示当前土耳其旅游业的现状,对中央和地方政府扮演的角色做出评析,希望从国家管理的风格和方式角度出发,使土耳其的旅游规划和政策取得实际效果。  相似文献

十月革命胜利后国外武装干涉和国内反动势力严重威胁着新生的布尔什维克政权。1918年起土耳其和英国军队先后占领巴库等石油产区,至1921年初苏俄石油出口量几乎为零。苏维埃政权稳固之后决定以出口石油换取外国设备和其他工业必需品,但收效不大。1923—1925年间西方大石油公司购买苏联石油产品的数量猛增并意欲控制苏联石油产品的出口和销售,苏联政府顺势而为,通过不断努力在世界石油市场上获得了一席之地。1926—1928年间英国等西欧国家在世界市场上排挤苏联石油,苏联遂与美国石油公司建立起伙伴关系,利用美国公司的营销网络与英国分庭抗礼。1929—1932年间英国停止抵制苏联石油产品,意味着英国要求苏联政府补偿企业国有化损失的方案落空,苏联获得了在世界市场上销售石油的合法权利。  相似文献

The number of occupational diseases in Mexico is alarming and clearly it is important to do studies with the purpose of improving the design of workstations. The objective of this research is to determine the maximum force levels in different positions of shoulder and elbow. An experiment was conducted with 16 subjects between 18 and 28 years old: 8 male and 8 female. We considered 16 different positions, working with the right and left arm to perform the tasks of pull and push. The tasks consisted of pushing or pulling a dynamometer for a period of 3 seconds as hard as possible. The results were presented in tables. The tables show the mean, standard deviation and range of force levels in different positions.  相似文献

Musicians have long been hampered by the challenge in turning sheet music while their hands are occupied playing an instrument. The sight of a human page turner assisting a pianist during a performance, for instance, is not uncommon. This need for a page turning solution is no less acute during practice sessions, which account for the vast majority of playing time. Despite widespread appreciation of the problem, there have been virtually no robust and affordable products to assist the musician. Recent progress in assistive technology and electronic reading devices offers promising solutions to this long-standing problem. The objective of this paper is to survey the technology landscape and assess the benefits and drawbacks of page turning solutions for musicians. A full range of mechanical and digital page turning products are reviewed.  相似文献

The placement of nasogastric (NG) tubes is known to be prone to error and may lead to serious issues for patient safety and wellbeing. In some instances these have been catastrophic and resulted in the death of the patient. This study sought to explore the potential risks associated with this procedure through the use of systematic prospective risk assessment. The research team used the Prospective Hazard Analysis (PHA) toolkit developed by Ward et al (2010) . The study has shown a wide number of risks that cover equipment design, work organisation, and training issues. The link between equipment design and training provides an important example of the need for a systematic approach to reducing errors and improving resilience in this aspect of healthcare.  相似文献

Finite Element Modeling (FEM) has become a vital tool in the automotive design and development processes. FEM of the human body is a technique capable of estimating parameters that are difficult to measure in experimental studies with the human body segments being modeled as complex and dynamic entities. Several studies have been dedicated to attain close-to-real FEMs of the human body (Pankoke and Siefert 2007; Amann, Huschenbeth et al. 2009; ESI 2010). The aim of this paper is to identify and appraise the state-of-the art models of the human body which incorporate detailed pelvis and/or lower extremity models. Six databases and search engines were used to obtain literature, and the search was limited to studies published in English since 2000. The initial search results identified 636 pelvis-related papers, 834 buttocks-related papers, 505 thigh-related papers, 927 femur-related papers, 2039 knee-related papers, 655 shank-related papers, 292 tibia-related papers, 110 fibula-related papers, 644 ankle-related papers, and 5660 foot-related papers. A refined search returned 100 pelvis-related papers, 45 buttocks-related papers, 65 thigh-related papers, 162 femur-related papers, 195 knee-related papers, 37 shank-related papers, 80 tibia-related papers, 30 fibula-related papers and 102 ankle-related papers and 246 foot-related papers. The refined literature list was further restricted by appraisal against a modified LOW appraisal criteria. Studies with unclear methodologies, with a focus on populations with pathology or with sport related dynamic motion modeling were excluded. The final literature list included fifteen models and each was assessed against the percentile the model represents, the gender the model was based on, the human body segment/segments included in the model, the sample size used to develop the model, the source of geometric/anthropometric values used to develop the model, the posture the model represents and the finite element solver used for the model. The results of this literature review provide indication of bias in the available models towards 50th percentile male modeling with a notable concentration on the pelvis, femur and buttocks segments.  相似文献

This work was undertaken in France at the request of a local fire and rescue school in order to conduct an analysis of driving two types of heavy rescue vehicle with a view to improving training. This study took place in a context of specialisation: the drivers of these vehicles will henceforth only perform this type of task. Consequently, specific training has been designed in advance. Our study concerns the improvement of this training, taking account of the particularities of driving these vehicles in emergency situations typical to the profession of fire-fighters. The results stress first that driving of rescue vehicles in emergency situations is a multidimensional collective activity. Driving strategies identified share certain common objectives: "optimising trajectories", warn other road users, anticipate their behaviour and leave room for manoeuvre to counter and react to any unexpected behaviour. They include risks management for the potential victims of the incident and the risk of accidents during the journey. These initial results help identify certain recommendations for the training courses dealing with driving vehicles in emergency situations. They also provide a warning concerning the possible consequences of driver specialisation.  相似文献

This paper proposes a method to identify opportunities for increasing the efficiency of raw material allocation decisions for products that are simultaneously targeted at multiple user populations around the world. The values of 24 body measures at certain key percentiles were used to estimate the best-fitting anthropometric distributions for female and male adults in nine national populations, which were selected to represent the diverse target markets multinational companies must design for. These distributions were then used to synthesize body measure data for combined populations with a 1:1 female:male ratio. An anthropometric range metric (ARM) was proposed for assessing the variation of these body measures across the populations. At any percentile, ARM values were calculated as the percentage difference between the highest and lowest anthropometric values across the considered user populations. Based on their magnitudes, plots of ARM values computed between the 1st and 99 th percentiles for each body measure were grouped into low, medium, and high categories. This classification of body measures was proposed as a means of selecting the most suitable strategies for designing raw material-efficient products. The findings in this study and the contributions of subsequent work along these lines are expected to help achieve greater efficiencies in resource allocation in global product development.  相似文献
