Study on Rural Leisure Tourism Planning from the Perspective of Global Tourism

In recent years, with the continuous growth of China's national income level and the continuous optimization of social and economic structure, the status of tourism in social development and the national economic system has gradually escalated. The thinking of global tourism will lead the development of tourism planning in the new era. Promoting global tourism is the repositioning of tourism development strategy in the new stage of our country. With the advent of the era of national tourism, tourists' requirements for the quality and mode of tourism have gradually improved. At the same time of popularization and nationalization of tourism consumption, it also puts forward the requirements of diversification of demand, quality of supply and diversification of main body. The whole country's rural tourism makes full use of the various resources of the tourist destination, and plans all the villages around the tourist route as scenic spots. Rural tourism is a tourism plan that coordinates urban and rural development and continuously promotes the optimization of tourism structure and re-allocates resources between urban and rural areas. In this way, we will improve the rural ecological environment and truly build beautiful villages.

Tactical planning and optimization of a milk run system of parts pickup for an engine manufacturer

A real-life milk run system designing problem of an engine manufacturer adopted JIT(just-in-time)production is studied.In the process of milk run system planning and design,the supply base is identified and a supplier site map is plotted for an arrangement of routes on which parts are periodically collected in a JIT manner from many scattered suppliers.With unit load designing,vehicle choosing and fleet sizing,pickup routing,vehicle assigning and scheduling problems are studied.Among these problems,a CVRP problem is identified and formulated as the key optimization in designing this milk run system,and it is solved through an optimization process.This tactical planning and optimization process gives a good solution to the real problem,and may shed light on the planning of similar systems.

Obstacles Facing Developing Countries in Power System Planning

The problem of power system planning, due to its complexity and dimensionality, is one of the most challenging problems facing the electric power industry in developing as well as developed countries. In planning phase, two of the most important decision-making parameters are the reliability and costs. The latter includes both system investment costs and outages costs. In this paper, these parameters are described and the interrelation between them is evaluated. Some previous approaches and developed techniques will he applied to a particular planning problem in a developing country and some aspects having a significant impact on the decision making process in the planning phase will be considered.

Tax Policy and Planning:Lessons From Developed Countries

One of the fundamental issues in developing countries is how to evolve tax policies that can generate sufficient revenue for government activities.Consequent upon the above,this study examined tax policies and planning in developing sub-Saharan African countries.It adopted table content analysis and descriptive statistics in its methodology.The study observed that aggressive tax planning which the Multi-National Corporations execute through royalty payment,interest payment,strategic transfer pricing and treaty shopping,among others,has caused countries around the globe huge revenue losses annually and has become a matter of serious concern to both the developed and developing economies.The implication of this is that achievement of objectives of tax policies and their reforms will remain a mirage in sub-Saharan African countries.The study concluded that the prevalence of illicit financial outflows in the form of tax evasion and avoidance in the guise of aggressive tax planning by multinational corporations,however,makes Africa’s tax policies worse.It was recommended that the Organization for Economic Corporation and Development,and the G-20 should involve developing countries in the Base Erosion and Profit Shifting project as they are the worst victims of these activities.

自然高温环境下5公里越野跑对血浆CK活性及MDA、SOD的影响

方法:抽取学员18名,随机分为室温组、高温组。室温组在室温28℃,湿度50%的环境下进行5公里越野跑;高温组在地面温度为40℃的环境下进行5公里越野跑。在运动前、运动后即刻、运动后3小时,抽取5毫升肘静脉血,进行血浆CK活性、MDA含量和SOD活性的测量。结果:自然高温环境下进行5公里越野跑后,血浆CK活性较室温组显著升高(p<0.05),MDA含量显著增加(p<0.05),SOD活性上升(p<0.05)。结论:自然高温环境下的5公里越野跑可能对机体造成更大的氧化刺激和更多的肌肉损伤,在自然高温环境下训练更应重视训练后的恢复和营养补充。

Perspectives on geospatial information science education:an example of urban planners in Southern Africa

Since the introduction of geographic information systems(GIS)in the 1960s,it has evolved tremendously to an extent that it permeates our daily lives.Initially,GIS usage started in the developed countries and now increasingly filtered to developing countries.The town planning profession was one of the early adopters of GIS.Geospatial information is a useful source of data that is needed in urban planning.In these days of the New Urban Agenda 2030,smart cities are even more required from planners in using geospatial information to face urban challenges such as sustainable urban development and climate change.Although GIS has promised a lot for urban planning,it has not reached its full potential.Moreover,many studies have focused on developed countries with limited studies on geospatial information application in municipalities and GIS education from a perspective of developing countries.In this study,a survey on the usage of geospatial information science(GSIS)in two cities,namely Bulawayo in Zimbabwe and Ekurhuleni in South Africa,was conducted,and an overview of the state of GIS curricula in planning schools is discussed.The results indicate that considerable progress has been made in the application of geospatial information in municipal planning;however,there are impediments limiting the full utilization of geospatial information in local municipalities.These impediments include:inadequate GIS curricula in planning schools,lack of resources,and lack of political will.These challenges manifest differently in well-resourced municipalities and those with limited resources.The study proposes planning-relevant GIS curricula to improve the level of GIS use in planning practice.
