“…First, in order to ensure production capacity, it is necessary to fully understand the market demand of the product. Wang et al (2019), according to a survey, found the willingness to buy for CBP products is $10.1 per capita, and analyzed the factors affecting residents' willingness to buy [57]. It is also necessary to adapt the needs of farmers to the local conditions and respect farmers' living habits, improve the accessibility and affordability [58].…”

China’s coal-based energy structure is the main reason for the current high-level air pollution and carbon emissions. Now in the North China Plain, the government is vigorously promoting “coal to gas” and “coal to electricity” in the country and the vast rural areas. The development and utilization of biomass resources in agricultural areas is also an effective means of replacing coal. We propose the idea of forming a complementary rural energy structure of “biogas, briquetting, electricity (BBE)” model based on centralized biogas production (CBP) and straw briquetting fuel (SBF) to improve the rural energy structure. This article uses emergy analysis methods to analyze actual cases. It needs to have strengths and avoid weaknesses in mode selection. The process of the analysis reveals the disadvantages and improvement measures. Under the current capacity load, the emergy input and output, eco-economic indicators, sustainable development indicators, environmental load indicators, and economic value have their own advantages and disadvantages. Assuming 100% capacity load, the indicators have great optimization space. Reducing labor input during the planting phase can effectively reduce emergy input. The government needs to provide corresponding support based on the strengths and weaknesses of the project to keep the project sustainability. The development of complementary integration based on local conditions is an important measure to optimize the energy consumption structure in rural areas and improve the ecological environment.

“…The new percentage of the proposed construction subsidy will cover 25% to 40% of the total investment. On one hand, the subsidy system should be based on demand response, whilst a reasonable subsidy rate is the premise of the effectiveness of the financial support policy [53]. Approximately 0.9 CNY/Nm 3 biogas is discussed as output subsidy.…”

Anaerobic digestion is one of the most sustainable and promising technologies for the management of organic residues. China plays an important role in the world's biogas industry and has accumulated rich and valuable experience, both positive and negative. The country has established relatively complete laws, policies and a subsidy system; its world-renowned standard system guarantees the implementation of biogas projects. Its prefabricated biogas industry has been developed, and several biogas-linked agricultural models have been disseminated. Nonetheless, the subsidy system in China's biogas industry is inflexible and cannot lead to marketization, unlike that of its European counterpart. Moreover, the equipment and technology levels of China's biogas industry are still lagging and underdeveloped. Mono-digestion, rather than co-digestion, dominates the biogas industry. In addition, biogas upgrading technology is immature, and digestate lacks planning and management. China's government subsidy is reconsidered in this work, resulting in the recommendation that subsidy should be based on products (i.e., output-oriented) instead of only input subsidy for construction. The policy could focus on the revival of abandoned biogas plants as well.Sustainability 2020, 12, 1490 2 of 21 effectively and widely implemented in countries where governments and institutions are involved in the subsidy, planning, design, construction, operation, and maintenance of biogas plants [7,8]. A number of countries in Asia and Africa have launched massive campaigns to popularize biogas technology via government support and international aid (Table 1) [9,10]. Globally, it is estimated that 50 million micro-digesters (family size), 132,000 biogas engineering projects (about 15,000 in Europe [11]) and 700 biogas upgrading plants are operating [12]. Promotion of biogas technology has several opportunities and obstacles. Numerous studies have focused on these aspects to discuss the country scenario. Many case and field studies have aimed to assess biogas technology to verify its multiple benefits [13,14] and identify potential barriers [8,[15][16][17][18][19][20][21]. However, these studies are limited to individual country scenarios. The progress and prospect of the biogas industry in different nations vary widely. Nearly no crosswise comparisons have been made for different countries. The current study intends to fill this gap.China leads the world in domestic biogas technology. With the expansion of the biogas industry, lessons learned, whether positive or negative, would be valuable and abundant for countries whose biogas industry is still at the initial stage, including nations mainly in South and Southeast Asia, Africa, and Latin America. Meanwhile, along with the development of medium-and large-scale biogas plants (MLBPs), progress is not trouble-free [22]. (According to the Chinese biogas standard NY/T 667-2011 Classification of Scale for Biogas Engineering, the thresholds of medium-scale and large-scale biogas plant are 300 m 3 and 500 m...

“…Knowledge, Attitude and Practice (KAP) are three evidence-based structures used to understand professionals' behavior and behavioral changes in oral care [21,22]. KAP regarding oral hygiene refers to knowledge as the "understanding of the topic regarding oral hygiene", attitude as "feelings towards oral hygiene, as well as predetermined ideas towards oral hygiene", and practice as "ways to demonstrate knowledge and attitudes through behavior towards oral hygiene [23,24]. Albrecht et al [25] conducted a systematic review to assess the effects of oral hygiene educational interventions for nursing staff or residents on the maintenance or improvement of the oral health of nursing home residents, which involved educational sessions on oral hygiene for nursing staff (five trials) or for both staff and residents (four trials).…”

Background: Oral hygiene is often neglected in clients receiving long-term care, suggesting that long-term care workers require formal oral hygiene education. Thus, the aim of this study was to investigate the effects of oral hygiene education on long-term care workers. Methods: This study utilized a mixed methods design. Eighty long-term care workers were recruited for participation in the oral hygiene education program, which employed three teaching methods: narration with multimedia presentation, demonstration, and teach-back. The effect of the education program on the participants’ level of oral hygiene knowledge, attitudes, and skills was measured using a structured questionnaire that was administered both pre- and post-delivery of the education program. Three months later, all participants submitted a self-report of their oral hygiene skills, and six participants completed a telephone interview. Quantitative data were analyzed using paired t-tests, and qualitative data were manually analyzed and coded. Results: Scores of oral hygiene knowledge (p < 0.001), attitudes (p = 0.001), and oral cleaning daily frequency for clients (p < 0.001), were significantly higher three months after undertaking the educational program. Conclusions: This preliminary study suggests that oral hygiene education may be effective in improving oral hygiene knowledge, attitudes, and skills among long-term care staff.
