Authors: Sun Hongliang 
Published: July 2023

Abstract
To be able to better improve the professional ability of environmental design students and cultivate applied technical talents, this paper proposes an analysis of the OBE theory for the reform of specialized and deeply integrated environmental design education. By establishing a mathematical model, the database is divided into different classes based on the similarity between data. The error value of the objective function is gradually reduced by repeated iterative operations. The data points are randomly selected to calculate the center distance, and the dense area of the input domain is obtained in the data set obeying Gaussian mixture distribution. Through iteration to find the optimal solution, adjust its speed and position so that the fitness function takes the maximum value. The speed is constantly revised according to its own experience and group information to enhance the global seeking ability, improve the local seeking ability of particles and avoid the oscillation phenomenon, and select the particle with the highest adaptability to calculate its average fluctuation value, to analyze the environmental design education reform under OBE theory. The result analysis shows that the correct rate of the algorithm analysis performance of this paper reaches 90.1%, which ensures more complete and accurate environmental design education data.

Published: July 2023

Abstract
Childhood is a critical stage for the development of perceptual and motor abilities, and strengthening the training of children with incomplete mental development at this stage will affect the development of motor skills during their growth. In this paper, we take VR technology as a starting point to build a perceptual model and introduce a convolutional sparse representation algorithm. First, a sparse representation with few non-zero elements is found to optimize a function consisting of a data fidelity term and a sparse induced penalty function. Then, the sum of the convolution of the filter and the convolution sparse feature map, i.e., the convolution operation, is computed to generate the translation invariants. Then the convolutional sparse coding method is introduced to the traditional unsupervised problem by calculating the minimization objective function and solving it in an iterative manner alternatively. Finally, the constituents of the signal are analyzed and the discrete equivalence of the convolution is derived based on the Fourier transform to derive the intervening variables. The experimental results showed that the mean value of the post-test of motor ability compared with the pre-test increased by 4.6 through an eight-week VR sports game training intervention study test on different children with incomplete mental development. Therefore, it is of great theoretical and practical significance to understand the characteristics of perceptual and motor abilities of children with incomplete intellectual development and to develop corresponding programs for VR sports game training according to their characteristics.

Authors: Yu Jia , Sang Linlin 
Published: July 2023

Abstract
An underground integrated pipeline corridor is a long-line structure that accommodates various municipal pipelines such as water supply, reclaimed water, storm water, communication, heat, electricity, and natural gas. Seismic hazard is the main factor affecting the safety of this important urban lifeline project, so the seismic analysis of the underground integrated pipeline corridor is urgent. To this end, in this paper, based on the generalized reaction displacement method, the finite element model of the standard section of the pipe corridor under the action of the earthquake is established, and the displacement, as well as the internal force response of the pipe corridor under the action of the earthquake, is obtained. The results show that the junction between the top of the standard section of the integrated pipe corridor and the outer slab is the key part for shear and bending tests, and the reinforcement in the span of the outer slab also needs to be focused on. Simulation and calculation by the physical stochastic seismic model in this paper show that the generalized reaction displacement method is more applicable and suitable for seismic finite element analysis of integrated pipe corridor, which lays the foundation for realizing refined analysis of dynamic reliability of underground integrated pipe corridor.

In this paper we review some of the environmental issues arising from Russian aggression, and we also refer to the effects of previous military conflicts of this kind. We deal with the pollution caused by war and the relationship between war and water. We touch on the destruction of some aspects of infrastructure (cultural goods, energy, health, transport) and its consequences.
Social Engineering in Europe’s Energy Crisis?
Authors: Kun Tamás 
Published: July 2023

Abstract
Today’s conflict of interests can be traced back to the Cold War. The present article reviews the past and current situation in Europe’s energy crisis from the start of the Russia-Ukraine war to its first anniversary. Since the US had the capability to export energy to its allies in Europe, they were able to use this opportunity to create a distance between themselves and Moscow in energy issues. The US has outrun Russia in the oil export race in recent years, and to counter this competitive threat, Russia had to act. Different narratives appeared in media reports on energy issues after the invasion of Ukraine, and policy makers often made confusing statements.

Published: July 2023

The effect of the ZnO/SnO2 ratio on phase formation and optical properties of the Zn-Sn-O compound was investigated by varying the ZnO/SnO2 molar ratio (ZnO/SnO2 = 1:2, 1:1, 2:1, 3:1, and 4:1). All samples were synthesised with high-energy planetary ball milling, followed by calcination at 1000 °C in the air. The result from X-Ray diffraction patterns (XRD) shows that the single-phase Zn2SnO4 is achieved at the ZnO/SnO2 ratio of 2:1. Whereas, the mixed phase of ZnO and Zn2SnO4 formed when ZnO is more than SnO2 (3:1 and 4:1). On the other hand, the XRD patterns of the products obtained at a ratio where SnO2 is more than ZnO present a mixture of SnO2 and Zn2SnO4. The photoluminescence of the two samples with the ratio of 2:1 and 1:3 gives full-visible range spectra from 400 to 800 nm, which are in the blue-far-red region centred at about 514, 580, and 690 nm. Temperature-dependent luminescence measurements were also carried out in this work, and the results indicate that the prepared phosphor Zn-Sn-O at the ZnO/SnO2 ratio of 1:2 has thermal stability. The obtained material was used to coat near UV LED chips, and the WLED possesses the highest CRI of 95. The SnO2-Zn2SnO4 powder can be used as a phosphor for WLED applications with high CRI and R9.

Published: July 2023

The most plentiful bioresource on earth is lignocellulosic biomass. The breakdown of lignocellulosic biomass attains different fermentable sugars which are considered to be very significant for the manufacturing of biogas, bioethanol etc. The major composition of lignocellulosic biomass is cellulose, lignin and hemicelluloses which are strongly linked with each other by hydrogen and covalent linkages thus generating a tough and rigid structure. The recalcitrant structure of lignin resists to solubilization thus arresting the degradation of cellulose and hemicelluloses present in bioplymeric structure. This addresses a striking challenge for the production of biofuels. To cope up with these limitations, immense research has been carried out for the development of pretreatment strategies. The present study utilized the alkaline pretreatment approach to digest cellulose, hemicelluloses and lignin content in locally available different agroindustrial wastes. This study employed Simultaneous Saccharification and Fermentation (SSF) process for bioethanol production from selected lignocellulosic biomass. Prior to fermentation all collected biomass was treated with 1% NaOH and then fermentation was carried out using Saccharomyces cerevisiae. The SSF was conducted at 30°C for 4-5 days. Along with pretreated biomass, untreated biomass was also subjected to SSF in order to compare the yield of bioethanol. The results of present research elaborate that pretreatment with 1% NaOH significantly degraded the complex polymeric structure of biomass hence induced enhanced production of bioethanol as compared to untreated agrowaste. Among all lignocellulosic biomass, pretreated banana peels attained higher production of bioethanol 118g/L with fermentation efficiency 139.75% and sugar utilization 97.9% than untreated banana peels achieved maximum ethanol production 42.4g/L with fermentation efficiency 53% and sugar utilization 68%. These findings indicate that before fermentation, a suitable pretreatment protocol must be applied to lignocellulosic substrates in order to increase the yield of ethanol and to meet the commercial needs.
