Historical, Architectural, and Structural Virtual Tour for Conservation and Maintenance of Architectural Heritage

ABSTRACT The Virtual Tour (VT) represents a key tool used in valorising and disseminating the historical and cultural value of built heritage. Basically, it has potential in supporting interdisciplinary technical activities associated with the historical and architectural aspects related to documentation and conservation. This paper defines the methodological lines into expanding the potentialities of the VT in the framework of a rational technical management and maintenance of historical assets from the Authorities. Thus, in addition to basic information related to historical and architectonical aspects, engineering technical data collected during the knowledge path recommended by relevant National and International codes, dealing with static and seismic performance assessment and the conceptual design of structural interventions, have been included in the VT. The designed STRAINS-VT (hiSToRical, ArchItectural aNd Structural–Virtual Tour) is conceived as a dynamic approach supporting the knowledge and monitoring of valuable assets in time, being open to updates and integration. Benefits associated with the application of the proposed STRAINS-VT have been investigated referring to a real architectural heritage building located in Abruzzi Region (Italy). Research outcomes showed that the knowledge process, which goes from the digital integrated survey and the in-situ structural characterization of materials and components to the analysis and design of structural interventions, can be profitably incorporated within the VT. Particularly, the STRAINS-VT operational framework represents an accessible and easy interpretable informative hub that support technical Authorities having in charge the conservation, maintenance, and restoration of valuable assets in the decision-making, validation, and commissioning of strengthening and maintenance works.

Development of agricultural competences as a priority factor of the sustainable development of Ukraine’s economy

Statement of the problem and its relevance. The intensification of crisis phenomena in the modern labor market in Ukraine is characterized by the insufficient level and number of specialists in the agricultural sector trained by the higher education system, the strengthening of the imbalance between the demand and supply of labor in Ukraine and abroad, large-scale destruction and risks, low labor efficiency and an insufficient and unstable level its payments in the agricultural sector. The current state, problems, and prospects of strengthening agro-economic competencies are studied. The purpose of providing modern educational services is to train future personnel capable of managing a modern enterprise based on environmental friendliness and circularity, to carry out the production and sale of environmentally safe food products that meet the needs of consumers, considering force majeure circumstances, changes in the culture of consumption and projected needs for strengthening the sustainability of business processes for future generations. Education for sustainable development requires the immediate development and implementation of a comprehensive program of continuous training and education of students in ecology, environmental protection, and rational nature management. Recently, as a result of the war, Ukraine has suffered significant losses of economic, ecological, social, and educational potential. This hurt the socio-economic indicators of the country's development, living standards, and population size. Changes to the legislation on several educational measures for adapting young people to new conditions and post-war reconstruction are proposed, and the main elements and competencies adapted to the modern risk conditions of economic development in the agrarian sphere are substantiated. Ukrainian agriculture can realize significant potential only by training young people with a high moral and ethical level who share the world values of sustainable development and care for the environment, an environment important for full entry into the global food market. Knowledge is of excellent importance for recovery and further sustainable socio-economic development in the information society's formation conditions. Their formation takes place as a result of the educational sector fulfilling its mission of socio-economic upliftment. Keywords: sustainable development, agrarian education, competitiveness, sustainable development strategies, post-war competences of the growth of the agro-industrial sector, efficiency of agricultural enterprises, modernization of institutions of higher agrarian education, agrarian economy.

SAFETY RISKOLOGY

Problem statement. The rapid expansion of the technosphere, unbalanced geopolitical, ecological, and biological processes of modern times demand a complete reassessment, a deep understanding, and the study of risk in all spheres of human life and activity. War and the non-trivial actions of aggressors force us into the necessity of reactive risk management, not excluding the need for proactive risk management. This complicates the determination of the priority of preventive measures at each stage of the activities of subjects and objects of risk, requiring the combination of these principles and the continuous reconsideration of risks to develop effective positive-compensatory measures. The actual state of human (humanity's) protection indicates that without the creation of a “science of risks”, without the establishment of a corresponding academic discipline, further effective and rational risk management is no longer possible. The purpose of the article. Justification for the Introduction of a New Academic Discipline “Safety Riskology” in Engineering and Technical Specialties at Higher Educational Institutions in Ukraine. Conclusions. The conceptual notion of “safety riskology” has been “synthesized” for the first time. The need for teaching a new academic discipline, “Safety Riskology”, in higher education institutions has been justified. During the instruction of this discipline, it is proposed to shape in learners advanced competencies in the identification, analysis, assessment, and compensation (balancing) of risk, considering the types and characteristics of the activities of risk subjects and objects. The demand for professionals with contemporary knowledge in safety riskology is identified across all sectors of the economy. Discussions on the initiation of the independent science of “Safety Riskology” have been initiated.

A Study on the Clinical Profile of Non-Organophosphorus Poisoning in a Tertiary Care Hospital

Poisoning is emerging as a very important global health issue particularly in agricultural countries like India. Although wide range of data is available on organophosphorus poisoning cases, studies and data are limited on non-organophosphorus compound poisoning like paraquat, rodenticide (zinc phosphide, yellow phosphorus, sodium monofluroacetate, fluroacetamide, arsenic, warfarins, and scilliroside etc.), pyrethroid, carbamate etc. The present study aims to study the clinical presentation and outcome of the non-organophosphorus poisoning cases. A cross sectional retrospective study was conducted at Assam Medical College and Hospital, Dibrugarh. In this study the data of the patients with nonorganophosphorus poisoning admitted to Assam Medical College from July, 2022 to July, 2023 were collected and analysed. A total of 104 patients were included in the study and most patients belonged to the age group of below 30 years. Out of all the cases highest number patients presented with Paraquat poisoning (48.1%), while distribution of other cases was as follows- Phenyl (12.5%), Pyrethroid (23.1%), Rodenticide (10.6%), Carbamate (1.9%) and Organochloride (3.6%). Vomiting was the most common presenting symptom. Hepatic and renal impairment was observed only in the paraquat poisoning cases and it was also associated with high mortality rate (88%). Acute Hepatitis and Acute kidney Injury was quite common among paraquat poisoning patients and mortality was mainly observed in paraquat, rodenticide and carbamate poisoning cases. Comprehensive care and awareness among general public is necessary for prevention and better management of poisoning cases. Development of proper rational management guidelines is also pivotal for reducing mortality in these cases.

The effect of health quotient and time management skills on self-management behavior and glycemic control among individuals with type 2 diabetes mellitus.

The aim of this study was to evaluate the present status of self-management behavior and glycemic control in individuals diagnosed with Type 2 Diabetes Mellitus (T2D), as well as to examine the impact of health quotient (HQ) and time management skills on both self-management behavior and glycemic control. Between October 2022 and March 2023, a purposive sampling method had been utilized to select 215 participants with type T2D. The survey concluded a general information questionnaire, an HQ scale, a diabetes time management questionnaire and a self-management behavior questionnaire. The health quotient(HQ)encompasses the individuals' knowledge, attitude toward health, and the ability to maintain their own well-being. The diabetes time management questionnaire was reverse-scored, with higher scores indicating an enhanced competence in time management. The path among variables was analyzed using structural equation modeling(SEM). SEM showed that the direct effect of HQ on time management was -0.566 (p < 0.05), the direct effect of time management on the effect of self-management was -0.617 (p < 0.05), the direct effect of HQ on self-management was 0.156, and the indirect effect was 0.349 (p < 0.05); the relationship between health quotient and self-management was partially mediated by time management, with a mediating effect size of 68.8%. In addition, self-management had a direct effect on HbAlc, with a size of -0.394 (p < 0.05); The impacts of both HQ and time management on HbAlc were found to be mediated by self-management, with HQ demonstrating an indirect effect of -0.199 (p < 0.05) and time management showing an indirect effect of 0.244 (p < 0.05). Health quotient and time management in patients with T2D serve as catalysts for self-management behavior. They affect HbAlc level indirectly through self-management practices. The suggestion is to prioritize the cultivation of rational time organization and management skills in T2D patients, as well as enhance their health quotient level. This can facilitate a more effective improvement in patients' self-management behaviors, ultimately achieving the objective of maintaining optimal glycemic control.

Quota Consolidation in Norwegian Coastal Fisheries

AbstractBalancing the trade-off between economic efficiency and social objectives has been a challenge for natural resource managers under rights-based management. While the actual prioritization should be guided by social preferences, the mechanisms and consequences of the quota transfer system need to be well understood. We investigate the effects of the quota transfer scheme implemented in the Norwegian coastal cod fishery in 2004. This is a small-scale fishery that has traditionally been important for employment in the northern part of Norway. Using vessel-level quota registry data, we estimate the effect of quota trading on vessel exit using a difference-in-differences approach that exploits variation in implementation timing between regulatory groups. In addition, we describe the outcome of quota consolidation with descriptive statistics. Our results confirm that the quota transfer scheme accelerates the exit of vessels from the fishery by at least 5% points in the short run. The descriptive analysis reveals great heterogeneity in both the size and geographic location of exiting vessels, suggesting that the scheme has distributional impacts. While the policy change has the expected effects in the short run, our results suggest that the implications of consolidation last longer. This has implications for policymakers trying to balance economic efficiency and social objectives of rational fishery management.

Response of bacterial communities, enzyme activities and dynamic changes of soil organic nitrogen fractions to six-year different application levels of biochar retention in Northeast China

Composition and availability of soil organic nitrogen play a key role in soil N retention and supply. The application of traditional chemical fertilizers can improve soil production and crop yields. However, it also leads to low N utilization efficiency and soil solidification. Previous studies have shown that fertilizers added with biochar can improve soil fertility and facilitate soil nutrient transformation by regulating soil biological indicators. However, whether biochar used with fertilizers can promote nutrient cycling in the long term, which remains to be tested. Therefore, this study aims to explore the long-term effects of biochar with different levels used with fertilizers on soil fertility, N supply potential of organic N, and microbial communities, thus, providing a theoretical reference for the rational management of biochar applications. In this study, a field experiment was carried out from 2013 to 2018 assess dynamic changes in organic N fractions and diversity and richness of microbial communities under the impacts of chemical fertilizers combined with different levels of biochar. Biochar with no amendment (CK), biochar with 15.75 t ha−1 (BC1), biochar with 31.5 t ha−1 (BC2), and biochar with 47.25 t ha−1 (BC3) are four biochar levels that were tested in this study. The results show that compared with CK, those other three biochar levels can increase soil organic matter, C/N, and pH values. Acid-hydrolysable N (AHN) makes a major contribution to organic N in soil. Biochar retention for six years has significantly affected AHN levels, as well as its four fractions, namely, amino acid N (AAN), acid-hydrolysable ammonium N (AN), amino sugar N (ASN), and hydrolysable unknown N (HUN). Some vital biological characteristics, with which each AHN fraction is primarily regulated, can be altered with the application of biochar. That is, AAN is mainly controlled by enriched Verrucomicrobia, Cyanobacteria, Glucosylbacteria, and Nitrospira, and reduced soil urease, while AN is mainly controlled by enriched Verrucomicrobia, Bacteroidetes, Gemmatimonadetes, Acidobacteria, and Proteobacteria. ASN is regulated by enriched Acidobacteria and depleted soil protease, while HUN is regulated by Gemmatimonadetes and enriched soil nitrate reductase. It has been found that microbial and soil enzyme activities are involved in N cycle processes, indicating that the formation of AHN fractions is closely associated with biochar-induced specific microbial and enzyme activities. This study has provided new insights into the influences of biochar with different levels on distribution of soil organic N fractions, and shifts in soil enzyme activities and microbial communities.

EVALUATION OF NORMALIZED DIFFERENCE VEGETATION INDEX IN WILD APPLE POPULATIONS GROWING IN SOUTHEAST MOUNTAIN REGIONS OF KAZAKHSTAN

Response of soil erosion resistance to straw incorporation amount in the black soil region of Northeast China

Straw incorporation has been considered as an effective environmental management application to improve soil erosion resistance (SER) and organic carbon sequestration. SER is useful to evaluate soil erosion subjected to concentrated flow. Nevertheless, few studies have been performed to examine how SER varied with the amount of straw incorporation on sloping croplands in high latitude and cool regions. In the current study, the fixed bed scouring tests were conducted in a large hydraulic flume using undisturbed soil samples taken from Hebei small watershed in the black soil region of Northeast China. The response of SER to different straw incorporation amounts (0, 1.125, 2.25, 4.5, 6.75, 9.0 and 13.5 t ha−1) was quantified after three months of straw decomposition. The major influencing factors and the corresponding mechanisms were determined. The findings demonstrated that rill erodibility firstly decreased exponentially with straw incorporation amount (R2 = 0.93), while it slightly increased when straw incorporation amount was more than 9.0 t ha−1. Critical shear stress firstly increased logarithmically (R2 = 0.90) and then slightly decreased when the amount exceeded 9.0 t ha−1. Compared to the treatment of 0 t ha−1, rill erodibility reduced by 17.0%–92.8% and critical shear stress increased by 59.6%–127.2% across different treatments of straw incorporation. Rill erodibility had significant and negative correlations with soil organic matter content, aggregate stability, cohesion, root mass density, straw mass density and straw decomposition amount. The key mechanisms for promoting SER were derived by the direct and indirect effects of straw incorporation and its decomposition on soil physicochemical properties and crop roots. The amount of 9.0 t ha−1 was recommended as the optimum amount of straw incorporation in croplands in Northeast China. These findings are useful to understand how soil erosion resistance responds to the amount of straw incorporation and make rational environmental management policy for semi-humid and cool regions.

Age and Growth of Japanese Anchovy (Engraulis japonicus, Temminck &amp; Schlegel, 1846) in Coastal Waters around Shandong Peninsula, China

Japanese anchovy (Engraulis japonicus) is a small pelagic fish with commercial and ecological importance. In spite of its importance, in recent years, specific research on anchovy in the Shandong Peninsula area has been relatively scarce and outdated. This study aims to estimate the age and growth characteristics of anchovy through year-round seasonal sampling from 2016 to 2017, utilizing length–frequency and otolith microstructure analysis. The higher coastal abundance and larger size observed in the spring and summer suggest a potential peak spawning period for anchovies dominated by larger-sized individuals. Based on otolith analysis, anchovies range in age from 0 to 4 years, with a limited presence at age 0 and dominance in the age-1 group. The length–weight relationship (LWR) equation shows hyper-allometric growth for each season, with a mean relative condition factor (Kn) of 1.025 ± 0.005, indicating good health. Additionally, the von Bertalanffy growth equation of can be expressed as Lt = 154.40 [1 − e−0.604 (t + 0.965)], suggesting a medium growth rate (K = 0.604). These findings contribute to the understanding of anchovy age and growth patterns, emphasizing the continuous need for research and monitoring to support rational and sustainable fisheries management and conservation efforts.

Application of selected groundwater quality indices in anthropogenically transformed areas

Correctly assessing the impact of waste landfills on groundwater quality requires the development and use of comprehensive tools that consider the content of individual components in water, as well as those relating to the hydrochemical background. The article presents a comparative analysis of selected water quality indices used around the world to assess the environmental threat caused by sources of pollution. The paper includes the following indicators: Water Quality Index, Landfill Water Pollution Index, Nemerow Pollution Index, Backman Index, Canadian Water Quality Index, Horizontal Ratio, Enrichment Factor and Fuzzy Water Quality. Attention was paid to the values of individual indices, their applicability in municipal and industrial waste landfills, and limitations in their use. A literature review has proven that some indices, such as the Landfill Water Pollution Index and Nemerow Pollution Index, are used very often as they provide reliable results. Index methods help conduct rational water management, complement groundwater quality monitoring, and serve as a tool for making decisions in various water protection areas.

Prenatal post-implantation development of collared peccaries (Pecari tajacu Linnaeus, 1758).

Given the importance of information on intrauterine development in diagnosing anomalies in the gestational development of the species for the development of assisted reproduction technologies as well as understanding the autonomy and responsiveness of the newborn, the aim of the present study was to describe the external morphology of collared peccary conceptuses. For this study, two conceptuses were used per gestational age of 25-120 days post-copulation (dpc) and neonates with 145 dpc, totalling 22 animals. Females were euthanised, and embryos/foetuses were examined, measured, and photographed. During the first third of the gestational period (25-50 dpc, n = 8), a marked body curvature, brain vesicles, somites, internal organs, placid lens, auricular protrusion and limb buds are noted. In the second third of the gestational period (51-100 dpc, n = 10), foetuses lose their body curvature, displaying greater anatomical definition, including skeletal, external ears, nostrils, eyelids and tactile hair formation and cranial suture closure. In addition, dorsal scent gland and genital tubercle differentiation were visualized at 50 days post-copulation. In the third of the gestational period (101-145 dpc, n = 4), the organs become completely formed, alongside skin darkening, eyelid opening, dental eruption, dorsal odorous gland development, sexual organ externalization, and fanero attachment development. These data allowed for the construction of a prenatal growth curve, providing comparative anatomy information for ungulates and further contributing towards rational reproductive management and reproductive biotechnologies for this species.

Nitrogen and phosphorus trends in lake sediments of China may diverge

The brief history of monitoring nutrient levels in Chinese lake waters limits our understanding of the causes and the long-term trends of their eutrophication and constrains effective lake management. We therefore synthesize nutrient data from lakes in China to reveal the historical changes and project their future trends to 2100 using models. Here we show that the average concentrations of nitrogen and phosphorus in lake sediments have increased by 267% and 202%, respectively since 1850. In the model projections, 2030–2100, the nitrogen concentrations in the studied lakes in China may decrease, for example, by 87% in the southern districts and by 19% in the northern districts. However, the phosphorus concentrations will continue to increase by an average of 25% in the Eastern Plain, Yunnan–Guizhou Plateau, and Xinjiang. Based on this differentiation, we suggest that nitrogen and phosphorus management in Chinese lakes should be carried out at the district level to help develop rational and sustainable environmental management strategies.

The impact of mispricing and growth opportunities on mergers and acquisitions of public companies from the behavioral theory of the firm

This paper examines the impact of the expectation gap of mispricing and growth opportunities on M&A motivation and performance from the perspective of the behavioral theory of the firm. The study proves that the expectation gap is a key factor that motivates firms to implement M&A decisions. When the expectation gap is negative, rational managers raise stock prices and improve the firm's operating conditions by implementing M&A. In addition, the firm's life cycle has a significant effect on the level of the expectation, while economic policy uncertainty weakens the effect of the expectation gap on M&A motivation and operating performance.

The Ecological Design of Marine Urban Green Space Plant Landscaping Based on the Concept of Sustainability.

With global climate change and accelerating urbanization, marine cities face unique environmental challenges. Ecological landscape creation is a form of design planning guided by the disciplines of landscape ecology and ecological aesthetics in the process of urban planning and construction. It seeks a design that can maintain the virtuous cycle of the ecosystem and at the same time maintain the spatial equilibrium of the dynamic development of urban landscapes, so as to make them have good ecological functions and corridor functions. The aim of this study is to explore the ecological design methods of plant landscaping in marine urban green spaces under the concept of sustainability. We first reviewed the concept of sustainable development and its application to urban green space design, especially the special requirements in the marine urban environment. This research focuses on how to select plant species that are adapted to the marine climate and how to promote biodiversity, enhance ecosystem services, and improve the quality of life of urban residents through eco-design approaches. Through the analysis of a number of domestic and international cases of green spaces in marine cities, we found that effective eco-design is not only about choosing the right plant species but also includes the rational management of water resources, soil protection, and ecosystem restoration, among other aspects. This study also points out that public participation and interdisciplinary cooperation play a crucial role in the ecological design process. Finally, this paper carries out a specific analysis of the landscape model landscape evaluation system for the ecological design of plant landscaping in marine urban green spaces and experimentally verifies that, compared with other styles, the experience of the European-style landscape is good overall. However, the view openness rating of the European style landscape is only about 0.42, and the best plant landscaping is the mixed mode of alkali poncho and salt poncho. This study aims to provide a practical reference and guidance for urban planners, landscape architects, and environmentalists.

Enhanced Water Quality Prediction in the Yellow River Basin: The Application of the HHO-LSTM Model

In the pivotal water resource region of the Yellow River Basin in China, precise prediction of water resources is essential for their effective and rational management. This study introduces a novel approach to water resource prediction by employing the Harris Hawks Optimization-Long Short-Term Memory (HHO-LSTM) model. This method overcomes the constraints faced by traditional techniques in processing time series data and various variable factors. It encompasses a comprehensive description of the multi-source hydrological data collection process within the Yellow River Basin, followed by meticulous data preprocessing. The data set for this study includes estimates of four critical water quality parameters, and the efficacy of the model is gauged through the mean squared error (MSE) and root mean squared error (RMSE) metrics. This facilitates the projection of future water quality trends in specific areas by leveraging historical water quality data. The HHO-LSTM model has demonstrated outstanding accuracy and robustness in predicting water quality across diverse temporal scales and water resource variables, marking a significant advancement in water resource management within the Yellow River Basin. This approach not only enhances current management strategies but also contributes valuable insights for ongoing water resource research and decision-making processes.
