In recent years, China's environmental condition becomes more and more serious and all kinds of pollution incidents happen frequently. Although government departments have implemented various policies and measures to curb the deterioration of the environment, public participation in environmental protection is the key solution of which the breadth and depth determines the level of environmental protection. This paper first analyzes the problems of public participation in environmental protection, such as defects of current legislation, low level of environmental awareness and participation, weak environmental NGOs etc. and then puts forward three ways to optimize the system of public participation in environmental protection by the example of Haikou City's "Two Constructions" Project, that is, perfect the relevant legal mechanism, increase publicity and support environmental NGOs. Finally the paper makes a summary and outlook of China's system of public participation in environmental protection. © Published under licence by IOP Publishing Ltd.

The growth and development of high-level female scientific and technological talents has become a global problem, facing severe challenges. The lack of high-level women in science and technology has become a global problem. How to recruit and help female scientists and technological talents grow raises awareness from the industry. To find out the main reasons for the lack of high-level female scientific and technological talent. This paper analyses the impact of gender discrimination on the lack of high-level female scientific and technological talents, the impact of disciplinary differences on female roles. The main reasons are: women's natural disadvantage of mathematical thinking; female birth, the traditional culture on the role of women and the impact of values. © Published under licence by IOP Publishing Ltd.

The issue of data aggregation in wireless sensor networks was studied. Data aggregation was an efficient in-network data processing method. It reduced data redundancy and improved information quality, which may save communication energy and increase collection efficiency. In this dissertation, data aggregation solution (DAS) was proposed and realized. DAS used a cluster structure based network and it had three parts. Firstly, the cluster head would not submit any packets derived from the cluster members. Instead, it fused them into an outcome packet and then sent it to the sink node. Secondly, the cluster head scheduled the nodes with low energy level into sleep. Thirdly, the cluster head would use a combined forecasting algorithm to estimate the data of sleeping nodes. Simulation tests were carried out, and simulation results showed that DAS had good performance. It not only extended the network lifetime greatly, but also provided better assurance of data quality. © 2016 SERSC.

As the main part of industrial production, the manufacturing industry promotes the economic growth of our country, but the subsequent large amount of energy consumption and greenhouse gas emissions have greatly undermined human's living environment. Therefore this paper aims at finding some solutions through the example of Hainan's low carbon manufacturing industry. It first analyzes the importance of low carbon economy for the development of the manufacturing industry, then describes the current status of Hainan's low carbon manufacturing industry, and finally puts forward five ways for the development of low carbon manufacturing in Hainan Province such as perfecting relevant laws and regulations, formulating supporting policies, setting up suitable industrial layout, improving the low-carbon technology innovation system, and establishing incentive mechanism of personnel in manufacturing enterprises. The third part is also the main innovation in this field. © The Authors, published by EDP Sciences.

The purpose of this paper is to make an economic evaluation of chemical construction projects on environmental impact. By analyzing the serious pollution and damage caused by the chemical industry, the construction project of chemical industry is analyzed, while reasonable and effective evaluation indexes and methods are established. Cost benefit method was used for the analysis. The index system for economic evaluation of chemical construction project was established, including environmental cost index and environmental benefit index. According to the method of economic evaluation of environmental impact of chemical construction project, each index is calculated, and the calculation formula of the index is obtained. Finally, it is applied to the project of ethylene expansion and extension project in chemical plant. The experiment result shows that the economic benefit is obviously lower than the economic benefit of environmental impact assessment. Based on the above finding, it is concluded that the feasibility of the evaluation method is verified and satisfactory results are obtained, which show that the economic evaluation of the environmental impact of chemical construction projects is feasible.

Nowadays, the game industry has entered a period of vigorous development, each game artificial intelligence has become the indispensable one element, so a good design can be seen as the soul of game, in almost all games have a kind of be good to hear or see appearance, the soul is attracted to the core game player. In this paper, the genetic algorithm becomes a new random search and optimization algorithm, the basic idea of the theory of evolution based on Darwin and Mendel genetics. Genetic algorithm for solving multi objective and complexity with the unpredictable nature of the problem, there is there is nothing comparable to this superiority. The shortest path problem of network is abstracted to a minimum spanning tree problem and the limitations of the minimum spanning tree are analyzed. The notion of the node degree is introduced. © (2014) Trans Tech Publications, Switzerland.

With the development of technology of construction engineering, natural diseases have warned the construction industry that the anti-seismic design must be applied to the construction engineering to ensure the construction quality. In the work, the anti-seismic design technique is used to solve the problems of the modern construction engineering in order to realize the high quality standard of construction engineering. In addition, the corresponding measurement and suggestion are proposed based on the anti-seismic maintenance and management of construction engineering. © 2015 Taylor & Francis Group, London.

This paper studies the improvement and implementation of access control method under ABAC model in detail. By further analysis of encyption principle and algorithm implementation process, and contrast on mainstream ABE algorithms, it selects CP-ABE as access control algorithm for security and performance, to be used in ABAC access control model under cloud computing environment. We improve the algorithm and optimize the system to reduce the computation during access control process. So it can well integrate with ABAC model to protect the privancy of information resource. The tests show the improved scheme has rapid speed in encryption/decryption with ABAC model, and needs smaller storage space, which is also a better encryption mechanism for cloud environment. © 2016 IEEE.

In the traditional teaching mode, teachers in order to establish the authority of the classroom, usually in front of the students showed severe image, this will enable students to have a psychological fear, this relationship will caused the gap between teachers and students and influence between teachers and students in the normal communication and students' healthy growth of teachers. We want to change the normal teacher-student interaction mode, so that teachers and students can be generated between the two-way communication, so that students in the physical and mental health development, learning in a happy environment. This paper expounds the concept of teacher-student interaction, according to the characteristics of physical education teachers and students, and puts forward the Countermeasures of the communication between teachers and students. © 2015 Di-feng Fan.

The work focused on the feasibility and realization approaches of rural tourism development in China. A feasibility analysis of the development of Chinese rural tourism was primarily made from four aspects—the benefits to the rural development, the environment, the urban residents, and the rural employment. Subsequently, reflections are made on the approaches to the development of rural tourism from three perspectives: (1) the development of sightseeing tour; (2) the development of agricultural production base with leisure functions; (3) the development of “Happy Farm Households Tour.” Suggestions for the development of rural tourism are proposed according to the current situation. © 2014 WIT Press.
