The Convention and Exhibition Industry is a trend-setting service industry that brings positive economic benefits to host countries, in addition to promoting international exchange and cooperation. It combines a range of businesses from trade, finance, sightseeing, and tourism among others, and its development brings considerable positive economic impact. With the growing divergence of environmental management standards of various industries, corporations now face ever pressing demand to gain an edge in the competitive global marketplace through measures such as adopting the appropriate green competition strategy, obtaining necessary environmental management certification, becoming accredited by customers' green supply chain audit process. This study uses DEA to evaluate the performance of environmental management systems based on artificial intelligence (AI). The evaluation process includes the choice of the proper input and output factors for valid assessment of each DMU's systematic performance. There are three input and output variables, and 12 DMUs, selected through a rigorous process from a range of samples comprised of different convention and exhibition companies in Taiwan. The data used in this study comprised of published documents and annual reports. The research results are the following. 1) There is one DMU with an AI-based environmental management system with an efficiency rating of 1, which qualifies as a strong form efficiency. Four DMU artificial intelligence environmental management systems have efficiency ratings between 0.9 and 1, and seven such systems with a rating below 0.9. 2) Recommendations based on slack variable analysis of convention and exhibition companies with input excess or shortage consist of necessary improvements that contribute to the industry's professional image, thereby placing the industry in a position of bringing significant business opportunities to host cities.
With the increasing threat of global climate change to mankind, it has become a global consensus to reduce carbon emissions. Low-carbon energy-saving buildings are energy-saving, environmentally friendly cities and towns marked by low energy consumption, low pollution and low emissions. It is a model that conforms to the development of urbanization with Chinese characteristics under the constraints of ecological environment. Based on the analysis of the development path of low-carbon energy-saving buildings, this paper proposes that low-carbon energy-saving buildings are a process of integrated development from “building energy conservation and green buildings” to “energy conservation and emission reduction” to “low-carbon energy-saving buildings”. The ecological model is an effective method to optimize the scientific development of low-carbon energy-saving buildings. Then the definition, classification, function and construction of ecological models are described. Then, the role of ecological model in the development of low-carbon energy-saving buildings in China is discussed.

Transformations to create more sustainable social-ecological systems are urgently needed. Network structures are often seen in many urban systems, such as urban transport system and urban functional networks; these networked urban systems can be described as social networks in which the nodes denote the individuals in the systems and the edges denote the relationships among the individuals. In the evolution of these networked systems, individual attributes play an important role but which were often ignored in previous studies. To address the effects of individual attributes in the evolution of networked systems, this paper presents an energy-based model to simulate the coevolution of network structures and individual attributes in social networks. Each node is endowed with an attribute vector representing its place in a multidimensional space. The evolution can be viewed as interaction among nodes, moving closer or farer away; an edge exists only when its two endpoints' distance is lower than a threshold. Every node tends to move to a low-energy place driven by attractive force from its immediate neighbors and repulsion force from all other nodes. A new place means a change of attributes. The simulation results show that individual attributes change in the evolution process while keeping the power-law degree distribution and generating clusters. Therefore, the energy model can imitate some complex social phenomena in networked urban systems by simple repulsion and attraction rules.
Environmental law as a science is being reconsidered because new environmental challenges and issues and their regulation require for theoretical understandings. International documents fixing the progressive world community's vision of prospects for the fight against global environmental issues serve as lawmaking acts. The United Nations Millennium Declaration 2000 (Chapter IV Protecting our common environment) is meant to be one of the strategic international documents stipulating cornerstone principles of environmental compliance and policy for the short-and long-term perspective. This article describes the principles and provisions declared in this document and their significance for international environmental law development.
Under the constraints of environmental impact assessment, in addition to considering the safety and economy of power system operation, attention should also be paid to CO2 emissions during operation. This paper studies the low-carbon dispatch problem of virtual power plant from two aspects of power generation resources and flexible load, and establishes a low-carbon dispatch optimization model considering the price response of demand-side carbon emissions. Firstly, the power generation plan is made considering carbon emission constraint for power sources. Secondly, the price response function of load is made in order to adjust the selling price of electricity to adjust the consumption of electricity and thus limit the carbon emission. Finally, the comprehensive operation costs of virtual power plant in different scenarios are analyzed through simulation examples. The low carbon and economy of the model is verified by the results of examples.
The advance of medical technology and the extended life expectancy have the elderly face more multiple problems. To cope with the aging society, the government and social welfare units should stress more on the elderly welfare, health care, and assistance in daily life. Young population migrating to cities for better job and life, female manpower largely involving in the labor market, large change in family structure, and rapidly increase in the elderly population have resulted in more situations of the elderly living alone. Aiming at the elderly in Shanghai, as the research objects, total 500 copies of questionnaire are distributed, and 364 valid copies are retrieved, with the retrieval rate 73%. The research results conclude 1. significantly negative effects of perceived health condition on medical ecology service use, 2. remarkably positive effects of social support on perceived health condition, and 3. notably negative effects of social support on medical ecology service use. According to the results, suggestions are proposed, expecting to provide reference for social affairs units promoting the inadequacy so that the elderly are able to independently take care of themselves. It would reduce national health care expenditure and enhance the elderly satisfaction with life.
