Enterprises are the basic cells of national economy, the ultimate force to promote economic and social development, and also the decisive factor for a strong country and a prosperous nation. There are a lot of theories about how to improve the market competitiveness and economic and social benefits of enterprises. They have their own characteristics and made due contributions to the economic and social development.
In the process of enterprise operation and management, with the development of science and technology and the improvement of the application level of network technology, the manual work mode and management mode have been unable to adapt to the development speed of modern society. Building management information system to meet the needs of enterprise modern management has become the future development direction of improving the work efficiency and standardized management of all departments. The core essence of enterprise material management is to use network technology and computer technology to integrate enterprise procurement and production resources, reduce operating costs, improve enterprise production efficiency, and ultimately achieve maximum value.
In recent years, with the economic and social development of our country and the introduction of a series of material supply management systems, the level of material management is getting higher and higher. However, in today’s prosperous society, the supply of materials exceeds the demand, and the economic benefits of enterprises are relatively good, the material procurement is big, the price is high or low, the production is guaranteed blindly, resulting in the material cost greatly increased, the reserve fund sharply increased, resulting in excessive reserves and extreme waste. At the time of market operation and economic benefit decline, facing the gradual improvement of operation awareness of enterprises in all walks of life, if we do not calculate and analyze, nor fully face material saving and thrifty, nor control the purchase volume to reduce the purchase cost, and generate the maximum benefit with the minimum investment, the enterprise will face the situation of operating difficulties until the loss.
In order to realize the information collection and processing, information resource sharing and decision-making assistant management between enterprises and different departments within enterprises, it is necessary to establish enterprise material management system. Its goal is to realize enterprise information network, information resource, management modernization and scientific decision-making.

With the rapid development of social economy, the change of natural environment and the frequent occurrence of disasters, people pay more attention to the quality and level of emergency medical care. With the unique position and function of nurses in disease, disaster and other medical practice becoming more and more obvious, how to cultivate nursing students with high level of first aid has become the top priority of current international nursing higher education.
There are eight chapters in this book. The first chapter introduces the basic situation and research status of first aid and first aid nursing, first aid medical service system, pre hospital first aid nursing and training; after that, we divided into seven chapters: basic rescue, first aid, pre hospital first aid, common emergency and critical cases, pre hospital common first aid technology, monitoring technology during the transportation of critical patients and pre hospital first aid training to study the basic knowledge of first aid nursing, on-site first aid process, emergency plan and pre hospital first aid technology and training of different critical cases.
This book can be used as training materials for professional first-aid institutions, reference books for professional pre hospital first-aid medical staff, as well as learning and reference materials for other relevant personnel.
Since the beginning of the 21st century, in order to promote the sustainable and healthy development of economy and accelerate the process of socialist modernization, China has clearly put forward the urbanization strategy, and the speed of urbanization has been accelerating. The corresponding infrastructure construction, such as urban indemnificatory residential engineering, transportation facilities, urban water supply, gas supply and heating facilities has also developed. However, at present, the funds in China’s financial budget are far from meeting the needs of infrastructure construction. At the same time, the private surplus funds have expanded unprecedentedly and maintained stable development. How to make better use of these non governmental capital and let it participate in the infrastructure construction of our country has become a realistic problem in front of us. The development of public private partnership (PPP) provides a way to solve this problem.
After the 18th National Congress of the Communist Party of China, the country has strengthened the Reform and Opening up. From the first mention of PPP mode at the Third Plenary Session of the 18th CPC Central Committee to the introduction of relevant policies by the National Development and Reform Commission and the Ministry of Finance, PPP mode has been gradually popularized in China and relevant policies have been gradually improved. PPP model not only uses idle social funds to relieve the pressure of financial budget funds, but also enables the government and the private sector to establish a cooperative relationship in the field of infrastructure construction, develop strengths and avoid weaknesses, and complement each others’ advantages, so as to better play their respective roles and advantages, reasonably allocate resources, put an end to resource abuse, optimize the allocation of resources, improve the use efficiency of resources, meet the public demand, improve the social governance function, and ensure the quality of infrastructure and public products.
进入 21 世纪以来， 为促进经济的持续健康发展， 加快社会主义现代化建设进程，我国明确提出城镇化战略，城镇化速度不断加快，相应的城市保障性居住工程、运输设施、城市供水供气供暖设施等基础设施建设也随之发展。但是，当前我国财政预算内的资金远远无法满足基础设施建设的需要，与此同时，民间剩余资金却空前膨胀，且保持了稳定发展。如何更好地利用这些民间资本，让其参与到我国基础设施建设中，成为摆在我们面前的现实问题。政府和社会资本合作模（Public PrivatePartnership，简称 PPP 模式）的发展为解决这一问题提供了思路。
党的第十八次全国代表大会以后，国家加大了改革开放的力度。从党的十八届三中全会首次提到 PPP 模式，到国家发改委、财政部等陆续出台相关政策， PPP 模式在国内逐渐得到了普及，相关政策也得到了逐步完善。 PPP 模式不仅利用社会闲置资金缓解了财政预算资金压力，而且使得政府部门和私营部门在基础设施建设领域建立起合作关系，扬长避短，优势互补，从而更好地发挥了他们各自的作用以及各自的优势，合理调配资源，杜绝资源滥用，优化了资源的配置，提高了资源的使用效率，满足了公共需求，完善了社会治理功能，保障了基础设施和公共产品质量。
China is a major agricultural country. As a primary industry, the development of agriculture is directly related to national economy and people’s livelihood. In the development of traditional agriculture, due to the reliance on manpower, there are strong limitations in crop types, yields and other aspects. The development of agriculture is inseparable from the support of science and technology. If we can make full use of science and technology to promote and spread agricultural knowledge and apply it to specific agricultural production, not only can more agricultural workers understand the relevant technology to achieve the effect of technology promotion and popularization, but also can effectively improve the efficiency of agricultural production and reduce the degree of human labor.
In addition to agricultural technology development and basic theories, this book also focuses on the whole process of agricultural breeding, planting, growth, management from the aspects of genetic improvement of crops, crop planting, agricultural technology service mode and mechanism, agricultural operation and management, and quality and safety management of agricultural products in China. Also, it summarizes the experience of technology and management from traditional agriculture to modernization and mechanization in China. It is a rare agronomy tool book suitable for popularizing agricultural technology.
With the development and progress of society, energy occupies an important position in the process of human development and is an important material basis, while coal is China’s main energy main body. For a long time, it has played an important role as the main body. With the needs of economic development, the extraction of energy has gradually deepened. The mining and utilization of coal must be comprehensively considered from the aspects of technology, safety, environment, and economy to achieve sustainable development of coal. The frequent occurrence of coal mining accidents now becomes the focus of future attention to the mining safety of coal mines. It is necessary to increase the innovative use of science and technology, study new mining technologies, ensure the safety of mining and sustainable development of energy, reduce the possible safety risks, and better promote the efficient mining and utilization of coal mines.
This book mainly explains the mining and safety management of coal mines in an all-round way, starting with the basic common knowledge of coal mining, and describes the technical methods needed for coal mining and the new technology research for safe coal mining, explain and manage the technical aspects of the coal mining process, pay attention to and study the safety issues in the coal mining process and the measures that need to be taken, establishment and management of the information system of coal mining. The coal mine should be exploited reasonably, not excessively, and keep the balanced development with the ecological construction.
