Intelligent Hotel Guidance System via Face Recognition Technology.

In modern large hotels, due to a large number of rooms and complex layouts, it is difficult for customers to find rooms, which increases a lot of workloads for hotel attendants to guide. In this paper, a hotel intelligent guidance system based on face recognition is designed. After entering the customer's facial photos, the room guidance and customer management are carried out through face recognition. With this, hotels can move toward card-free management, green environmental protection, and save on resources. With these improvements, hotel management will be card-free and green. Each monitoring device of the system adopts dual STM32 core architecture, in which STM32H7 is responsible for face recognition, while STM32L4 is the main control chip, which is responsible for data exchange, guest room guidance and other work. The monitoring master not only guides, but also uploads customer check-in information to the cloud platform to facilitate the management of the hotel. The system adopts contactless information collection and guidance, which improves the intelligence and humanization of the hotel, and has a good application prospect.

Assessing the environmental effects of ICT and renewable energy: roles of financial development, innovation, and trade.

In today's world of rapidly expanding economies, the fundamental aim of most nations is to raise the quality of living for their citizens. The investigation aims to analyze how environmental rules affect the emergence of environmentally conscious economies. This research focused on China's 26 provinces to investigate the elements influencing green economic development. These components included information and communication technology (ICT), industrial structure (IND), human capital (EDU), and foreign direct investment. Spatial modeling and SBM methods were utilized to show that there is still a connection between the variables after all these years using yearly time series data that began in 2000. Overall, the results suggest that environmental regulation helps green economic development (GDE), whereas industrial structure significantly hinders. Similar to the previous point, information and communication technology has a favorable influence on building a sustainable economy. The problem of ensuring long-term economic growth via information and communication technology is complicated and has scholars engaged in exciting discussion. The expansion of the green economy is also affected by factors such as human capital and foreign direct investment. This study's findings illuminate the economic effects of environmental regulations and support the contention that such laws are necessary for accomplishing the win-win goals of green economic development and environmental protection. This means that the research provides a fresh perspective to consider the monetary effects of environmental restrictions.

Can environmental tax improve the environmental investment? Evidence from a quasi-natural experiment in China.

The implementation of the Environmental Tax Law is a milestone in promoting China's green tax reform. However, the existence literature has lacked attention to whether it leads enterprises to invest in green environmental protection. To examine the Environmental Tax Law effects and mechanism on the environmental investment of heavy-polluted enterprises, this study used the data of heavy-polluted enterprises listed on the A-share market from 2012 to 2020 and regarded the Environmental Tax Law as a quasi-natural experiment to employ a difference-in-differences model. We found that environmental tax improves the green environmental investment of heavy-polluted enterprises, reflecting the guiding role of policy on enterprise investment allocation. Heterogeneity was found, and the promotion effect of environmental tax reform on enterprise environmental investment is more significant in non-nation-owned, central-western regions, and small-scale enterprises. Further analysis believed that market competition, as an external mechanism, helps strengthen environmental tax reform's implementation effect. The findings of this paper provide a new proof for a comprehensive understanding of the micro-effect of environmental tax reform and provide a reference for the implementation of green development strategies.

The Axial Compression Behavior of Basalt Fiber-Reinforced Recycled Aggregate Concrete-Filled Circular Steel-Tubular Column

Recycled aggregate concrete (RAC) technology has received a lot of attention as a green environmental protection technology. However, the unsatisfactory mechanical behavior of RAC restricts its application in engineering practice. The structure of basalt fiber-recycled aggregate concrete-filled circular steel tubes (C-BFRACFST) can dually improve the mechanical behavior of RAC. To observe the axial compression behavior of the C-BFRACFST column, seven specimens were designed with recycled aggregate replacement ratio (0%, 50%, 100%), basalt fiber (BF) content (0 kg/m3, 2 kg/m3, 4 kg/m3) and length–diameter (L/D, 5, 8, 11) as variable parameters for axial compression tests. The failure mode, load–displacement/strain curve, axial compression deformation, ultimate bearing capacity, energy dissipation, and ductility of specimens have been analyzed. The derived constitutive relation of core basalt fiber-reinforced recycled aggregate concrete (BFRAC) constrained by the circular steel tube and the 3D finite element model of C-BFRACFST column have been established to simulate the whole process of compression. It is observed that instability or shear failure occurs in specimens under axial compression load. When the recycled aggregate replacement ratio was increased from 50% to 100%, the change in the energy-dissipation capacity of the specimens was not significant but the ultimate bearing capacity and displacement ductility coefficient decreased by 3.45% and 8.91%, respectively. When the BF content was increased from 2 kg/m3 to 4kg/m3, the change in the ultimate bearing capacity of specimens was not significant; the energy-dissipation capacity at the later stage of bearing increased, and the displacement ductility coefficient was noted to increase by 13.34%. When the L/D was increased from 8 to 11, the energy-dissipation capacity of specimens was decreased, and the ultimate bearing capacity and displacement ductility coefficient declined by 1.37% and 43.52%, respectively. The finite element simulation results are in agreement with the test results.

The sustainable and coordinate progress of construction and environmental protection

It is the common goal of all mankind to advocate green environmental protection, control environmental pollution, reduce energy consumption and achieve sustainable development. At present, although our country pays a certain degree of attention to environmental protection, and the enterprises and constructions that produce a lot of pollution have been treated, in the long run, the form of environmental protection is still severe and unforgivable. Finding a balance between the contradictions of the project side and the owner side, the successful completion of the construction while reducing the environmental impact, and the protection of the environment in the urbanization process always come before the construction. Improving the content of each stage of building construction under the premise of environmental protection is the ultimate balance for the two. Environmental problems that arise should be actively resolved and summarized to form an institutionalized and standardized management system. This study aims to conduct an in-depth discussion and analysis of both architecture and the environment. This will lay the foundation for the infiltration of the concept of environmental protection during construction in the future and will promote the sustainable development of the construction industry at a lower environmental cost in the future.

Bio-derived 1T-MoS2/C-based aerogel by synergistic solar evaporation and tetracyclines removal for efficient freshwater generation

Tetracycline, a broad-spectrum antibiotic, has been widely used in disease treatment and other fields. However, due to the unreasonable use, tetracycline residue remains in water which eventually endangers human health. The green environmental protection, low-cost, and renewability biomass aerogel are highly attractive for the purification of tetracycline wastewater. Here, the flower-like 1T-MoS2 with S vacancies was uniformly grown on the supporting poplar catkin fibers-based biomass carbon matrix, which was constructed 3D porous aerogel by ice template method. The adsorption kinetics and adsorption isotherms model of MoS2/C-based aerogel for tetracycline in wastewater was investigated, revealing a maximum adsorption capacity of 124.4 mg g−1. More notably, the MoS2/C-based aerogel displayed excellent photothermal performance, which could synergistically raise the local temperature. The solar evaporation induced transpiration was able to accelerate the adsorption of tetracycline, owing to the endothermic behavior of tetracycline adsorption process. The MoS2/C-based aerogel attained an excellent water evaporation rate of 2.54 kg m−2 h−1 under one sun illumination, which is 11 times that of pure water. The solar purification prototype-based on MoS2/C-based aerogel could effectively remove tetracycline and generate freshwater. The freshwater production was about 33.6 kg m−2, and the tetracyclines were completed removed in the generation of condensed water on sunny days. The unique bifunctional capability of the MoS2/C-based aerogel paved a new strategy for tetracycline wastewater treatment and alleviated the dilemma of global water.

Modeling the intention and donation of second-hand clothing in the context of an emerging economy

The culture of fast fashion accelerates the consumption rate of individuals but at the expense of significant environmental stress. With a large amount of discarded clothing accumulating in landfills, it is crucial to encourage people to dispose of second-hand clothing (SHC) as sustainably as possible, especially in an emerging economy with large volume consumption. Through a survey of 619 respondents from China, this study explored the factors affecting people’s intentions and actual donation behaviors toward SHC. It extends the theory of interpersonal behavior (TIB) with environmental factors to construct a research framework, which included cognitive factors (attitude towards sustainable consumption), social factors (sense of community) and personal factors (perceived hedonic benefit) under TIB and the environment factors refers to problem awareness and ascription responsibility. Partial least squares structural equation modeling was employed to analyze the data. The findings revealed that attitudes toward sustainable consumption, problem awareness, ascription of responsibility, sense of community, and perceived hedonic benefit significantly and positively influenced people’s intentions and practices of SHC donation. This study will aid governments and relevant green environmental protection organizations in formulating more precise strategies for sustainable development, and promote relevant research on the sustainable disposal of SHC.

Furoic acid-mediated konjac glucomannan/flaxseed gum based green biodegradable antibacterial film for Shine-Muscat grape preservation

Considering the growing threats to the environment and human health, such as plastic pollution and food spoilage, the development of naturally antibacterial food packaging materials with biodegradable capabilities has recently attracted considerable attention. This work applies the concept of green environmental protection to packaging technology, and a new type of green edible antibacterial packaging film was developed. The basic idea is to incorporate furoic acid (FA), which possesses excellent antibacterial activity, into the flaxseed gum and konjac glucomannan matrix (FK) as a filler to obtain a series of FK-FA bioactive films. This incorporation simultaneously improves the hydrophobicity and UV-barrier ability by 12.28 % and 42.87 %, respectively. Meanwhile, the diameters of the antibacterial zone of the FK-FA0.4% films (composite FK films containing 0.4 % FA) against E. coli and S. aureus increased to 38.98 mm and 36.29 mm from 24.00 mm of pure FK film, respectively. As a consequence, the grape sample sealed with FK-FA0.4% film remained edible on the 18th day of storage, while those packaged with commercial PE film and pure FK were seriously rotted and lost edible value on the 12th day, further confirming the enhanced preservation capacity. Finally, the as-prepared films were established to be biodegradable and were almost completely degraded within 25 days under simulated environmental conditions. Overall, these promising results show the potential of FK-FA films for replacing plastic packaging materials as eco-friendly edible films with prolonged shelf life for active packaging.

Research Progress of Organic Corrosion Inhibitors in Metal Corrosion Protection

Metal materials are vulnerable to corrosion in the process of production and service, which often leads to serious disasters, including the decline of the performance of metal components and the shortened service life, and even causes catastrophic accidents and ecological damage. Adding a certain amount of corrosion inhibitors (CIs) to the corrosive medium is a simple, efficient, and economical anti-corrosion method to slow down and restrain the corrosion of metal materials. Organic corrosion inhibitors (OCIs) are considered to have good application prospects and are widely used for surface anti-corrosion of metal materials, as they generally have advantages such as good metal adsorption, low oxidation resistance, good thermal and chemical stability, and green environmental protection. This paper systematically summarized some major OCIs, including alkyl chains, imidazoles, and pyridines, and their structural characteristics, as well as the action mechanism of OCIs. Moreover, this paper discusses some natural compounds used as environmentally friendly CIs and provides a prospect for the development trend of OCIs.

Does the carbon emissions trading scheme improve the corporate environmental information disclosure level? Evidence from China

Recently, a great deal of literature has discussed the effects of the carbon emissions trading scheme (CETS) and the factors that affect the corporate environmental information disclosure (CEID) level. However, no researchers have studied how CETS affects the CEID level. Based on a difference-in-difference-in-differences model, we discover that CETS can improve the CEID level. The findings are robust and persistent even after testing for time lags and leads effects, changing the measure of the dependent variable, testing for enterprise relocation, adjusting the fixed effect method, testing for concurrent policies, and performing placebo tests. The reason is that CETS can encourage corporate green technology innovation and environmental protection investment, thus improving the CEID level. Further investigation reveals that the impact of CETS on promoting the CEID level is more significant when the following conditions are met: the enterprises are in provinces and cities in the east and northeast; they are state-owned; and they have strong political connections. This paper expands on the current field of research on the influence effects of CETS, broadens the understanding of the factors influencing the CEID level, and investigates the mechanism by which CETS improves the CEID level.

Key factors influencing mass willingness to use CESPs under green concept: ECOCO smart recyclers as a case study

In promoting green life and environmental protection, encouraging mass participation in environmental protection activities and increasing mass willingness to use circular economy service platforms (CESPs) are of high importance. In light of this stance and other several dimensions, including green concept, hedonic value, and user benefits, the multiple attribute decision-making technique was used to develop an evaluation model that assesses the influential factor of one's willingness to use CESPs. By employing the decision-making trial and evaluation laboratory (DEMATEL) approach, the degree of mutual influence between different evaluation dimensions and criteria was first determined to generate an influential network relation map (INRM). Next, the weights of influence of varying evaluation dimensions and criteria were calculated by combining the DEMATEL approach with analytic network process. Finally, an empirical analysis of comprehensive performance of different evaluation dimensions and criteria was carried out based on the modified VIKOR technique. Referring to the INRM, green information emerged as the primary aspect that should be improved and adjusted, followed by green management, hedonic value, user benefits, green appeal, and green participation in order of priority. These outcomes may serve as reference regarding ways to enhance mass willingness to use the ECOCO CESPs and its smart recyclers.

Risk-averse two-stage stochastic programming-based closed-loop supply chain network design under uncertain demand

In recent years, there has been a growing awareness and acceptance of the concept of green environmental protection among the public, primarily due to the worsening environmental issues and increased emphasis by governments on corporate social responsibility regulations. As a result, the management of closed-loop supply chains has gained significant attention from both businesses and researchers. Most stochastic programming models addressing closed-loop supply chain (CLSC) under uncertainty are typically designed to be risk-neutral. In this paper, a risk-averse two-stage stochastic programming (RATSSP) model for the closed-loop supply chain network design (CLSCND) problem considering facility capacity level decisions under uncertain demand. It is aiming to trade off the expected total profit and the profit risk, based on a given degree of responsive risk aversion. Due to the NP-hard nature of the CLSCND problem, this paper applies simplified swarm optimization (SSO), genetic algorithm (GA), and particle swarm optimization (PSO) algorithms to solve the problem. To improve the efficiency and quality of the obtained solutions, we propose a parallel computation meta-heuristic algorithm, parallel simplified swarm optimization (PSSO), along with parallel versions of PSO and GA. Computational results show the effectiveness of our proposed model, with PSSO demonstrating the best robustness and solution quality among the considered algorithms.
