Effects of Clipping Intensity on the Physiology of Dicranopteris pedata and Its Interroot Soil in the Rare-Earth-Mining Area in Southern China
Authors: Lin Yu , Chen Zhiqiang , Li Weiye , Chen Zhibiao
Published: January 2024

Clipping is crucial during phytoremediation. However, research into the effects of clipping intensity on the physiology of Dicranopteris pedata (D. pedata) and its interroot soil in the rare-earth-mining area in southern China is lacking. A clipping experiment was conducted to verify the phytoremediation effect of D. pedata. The physiology of D. pedata, such as biomass, antioxidant enzymes, chlorophyll, and rare-earth elements (REEs), were determined after clipping. And the microbial community diversity and soil enzyme activities in the interroot soil of D. pedata were investigated. The phytoremediation efficiency was determined at the end of the experiment. The results showed that the compensatory growth effect of D. pedata was stronger with increasing clipping intensity. There was no significant difference in the α diversity of interroot soil microorganisms of D. pedata at different clipping intensities, but β diversity analysis showed that the clipping treatment group deviated from the control group. Only urease activity decreased among the interroot soil enzymes in D. pedata after clipping, while the soil catalase and sucrase were less responsive to clipping. The REEs accumulated by D. pedata were dominated by light REEs in the aboveground part of the plant, while the amounts of light and heavy rare-earth elements accumulated in the underground part of the plant were similar. The phytoextraction of REEs gradually increased with increasing clipping intensity. It was concluded that 100% clipping once a year is the most appropriate when considering D. pedata’s phytoremediation potential and soil system. The time it takes for 100% clipping of D. pedata to reduce the soil TREEs (total rare-earth elements), LREEs (light rare-earth elements), and HREEs (heavy rare-earth elements) to below-average soil REE concentration in China was estimated to be 25.54 years, 19.56 years, and 65.43 years, respectively, which was significantly lower than that for other clipping intensities and the control group. It is concluded that clipping D. pedata is an effective way to promote phytoextraction efficiency in the southern rare-earth-mining areas. The soil can still support the resumption of D. pedata growth after high-intensity clipping.

Published: January 2024

Due to the complexity of digital equipment and systems, it is quite difficult to obtain a precise mechanism model in practice. For an unknown discrete-time nonlinear system, in this paper, a semi-parametric model is used to describe this discrete-time nonlinear system, and this semi-parametric model contains a parametric uncertainty part and a nonparametric uncertainty part. Based on this semi-parametric model, a novel data-driven control algorithm based on an information concentration estimator and regularized online sequential extreme learning machine (ReOS-ELM) is designed. The information concentration estimator estimates the parametric uncertainty part; The training data of ReOS-ELM network is obtained, based on symmetry and information concentration estimator, then the training of ReOS-ELM network and the estimate of nonparametric uncertainty part using ReOS-ELM network are carried out online, successively. A stability analysis and three simulation examples were performed, and the simulation results show that the proposed data-driven control algorithm is effective in improving the control accuracy.

Published: January 2024

C. vulgaris has a positive effect on the removal of nutrients from pig farm biogas slurry. However, swine wastewater often contains heavy metal ions, such as Cu (II), which may have impacts on the nutrient removal performance of C. vulgaris. Additionally, the heavy metal ions in wastewater can be adsorbed by microalgae. In this study, the stress effect of Cu (II) on the growth of Chlorella vulgaris, the Cu (II) removal by microalgae, and the effect of different concentrations of Cu (II) on the nutrient removal efficiency of C. vulgaris in biogas slurries were explored. The results showed that the microalgae biomass of microalgae on the sixth day of the experiment was the highest in the treatment with a Cu (II) concentration of 0.5 mg/L, which was 30.1% higher than that of the 2.5 mg/L group. C. vulgaris had higher removal efficiencies of Cu (II) at a Cu (II) concentration of 0.1~1.5 mg/L. The–OH, C=O, –COOH, and C–O groups on the surface of the algal cells play a significant role in the removal of Cu (II). The removal rates of COD, NH3–N, TN, and TP by C. vulgaris at a Cu (II) concentration of 0.5 mg/L were the highest, which were 89.0%, 53.7%, 69.6%, and 47.3%, respectively.

Authors: Li Mengci , Wu Chao , Kang Zhe , Liu Chengzhi , Deng Shiyu , Li Zhenwei
Published: January 2024

The real-time light curve classification of transients is helpful in searching for rare transients. We propose a new algorithm based on machine learning, namely the Temporary Convective Network and Light Gradient Boosting Machine Combined with Weight Module Algorithm (TLW). The TLW algorithm can classify the photometric simulation transients data in g, r, i bands provided via PLAsTiCC, typing Tidal Disruption Event (TDE), Kilonova (KN), Type Ia supernova (SNIa), and Type I Super-luminous supernova (SLSN-I). When comparing the real-time classification results of the TLW algorithm and six other algorithms, such as Rapid, we found that the TLW algorithm has the best comprehensive performance indexes and has the advantages of high precision and high efficiency. The average accuracy of TLW is 84.54%. The average implementation timings of the TLW algorithm for classifying four types of transients is 123.09 s, which is based on TensorFlow’s architecture in windows and python. We use three indicators to prove that the TLW algorithm is superior to the classical Rapid algorithm, including Confusion Matrix, PR curve, and ROC curve. We also use the TLW algorithm to classify ZTF real transients. The real-time classification results for ZTF transients show that the accuracy of the TLW algorithm is higher than the other six algorithms.

Published: January 2024

The quality of cellular products used in biological research can directly impact the ability to obtain accurate results. Epstein–Barr virus (EBV) is a latent virus that spreads extensively worldwide, and cell lines used in experiments may carry EBV and pose an infection risk. The presence of EBV in a single cell line can contaminate other cell lines used in the same laboratory, affecting experimental results. We developed three EBV detection systems: (1) a polymerase chain reaction (PCR)-based detection system, (2) a recombinase polymerase amplification (RPA)-based detection system, and (3) a combined RPA-lateral flow assay (LFA) detection system. The minimum EBV detection limits were 1 × 103 copy numbers for the RPA-based and RPA-LFA systems and 1 × 104 copy numbers for the PCR-based system. Both the PCR and RPA detection systems were applied to 192 cell lines, and the results were consistent with those obtained by the EBV assay methods specified in the pharmaceutical industry standards of the People’s Republic of China. A total of 10 EBV-positive cell lines were identified. The combined RPA-LFA system is simple to operate, allowing for rapid result visualization. This system can be implemented in laboratories and cell banks as part of a daily quality control strategy to ensure cell quality and experimental safety and may represent a potential new technique for the rapid detection of EBV in clinical samples.

The availability of water is crucial for the growth and sustainability of human development. The effective management of water resources is essential due to their renewable nature and their critical role in ensuring food security and water safety. In this study, the multi-step-ahead modeling approach of the Gravity Recovery and Climate Experiment (GRACE) terrestrial water storage (TWS) was utilized to gain insights into and forecast the fluctuations in water resources within Saudi Arabia. This study was conducted using mascon solutions obtained from the University of Texas Center for Space Research (UT-CSR) over the period of 2007 to 2017. The data were used in the development of artificial intelligence models, namely, an Elman neural network (ENN), a backpropagation neural network (BPNN), and kernel support vector regression (k-SVR). These models were constructed using various input variables, such as t-12, t-24, t-36, t-48, and TWS, with the output variable being the focus. A simple and weighted average ensemble was introduced to improve the accuracy of marginal and weak predictive results. The performance of the models was assessed with the use of several evaluation metrics, including mean absolute error (MAE), root mean square error (RMSE), mean absolute percentage error (MAPE), correlation coefficient (CC), and Nash–Sutcliffe efficiency (NSE). The results of the estimate indicate that k-SVR-M1 (NSE = 0.993, MAE = 0.0346) produced favorable outcomes, whereas ENN-M3 (NSE = 0.6586, MAE = 0.6895) emerged as the second most effective model. The combinations of all other models exhibited accuracies ranging from excellent to marginal, rendering them unreliable for decision-making purposes. Error ensemble methods improved the standalone model and proved merit. The results also serve as an important tool for monitoring changes in global water resources, aiding in drought management, and understanding the Earth’s water cycle.
Effects of Film-Mulched Rock Outcrops on Rainwater Redistribution and Maize Growth in the Cropland of a Rocky Karst Area
Authors: Zhao Zhimeng , Deng Jiabin , Zhang Jin , Shen Youxin
Published: January 2024

Film-mulched rock outcrops are a proven way to effectively prevent preferential flow at the rock–soil interface in rocky karst areas, but the impact on rainwater redistribution and maize growth in farmland areas has never been studied. This paper used the dye tracer method at a sprinkling intensity of 1 mm min−1 to study the rainwater redistribution in soils for three different treatments: away from rock (AR), close to rock (CR), and close to film-mulched rock (CFMR). The growth situation of maize (Zea mays L.) according to the different treatments was also studied. It was shown in the study that the rainwater gathered by rock outcrops was mainly confined only within a narrow flow path at the rock–soil interface in the CR treatment, with a preferential flow fraction of 35.78~55.54% and dyeing depth of 15.37~20.00 cm across the three dye application amounts (850 mL, 1700 mL, and 3400 mL) in contrast to the uniform distribution of the rainwater in the soil of the AR treatment, with a preferential flow fraction of 12.31~37.15% and dyeing depth of 6.93~14.00 cm. Interestingly, in the CFMR treatment, there was no preferential flow at the rock–soil interface benefiting from the film’s blocking action, and the redistribution of rainwater was mainly based on the matrix flow, with a preferential flow fraction of 24.93~39.62% and dyeing depth of 10.27~18.00 cm, indicating that the film-mulched rock outcrops improved the rock’s output capability for gathering rainwater into the surrounding soil. In addition, film-mulched rock outcrops can promote the growth of maize, as indicated by the results for plant height, stem diameter, maximum leaf area, SPAD value, and floral development of maize, which increased in order from AR, CR, to CFMR. Our study suggests that film-mulched rock outcrops have important implications for the efficient use of rainwater and the growth of crops in rocky karst areas, as well as in regions with similar geological characteristics.

Published: January 2024

To analyze the operation risk of check dams under extreme precipitation conditions, taking Ningxia area as an example, this paper carried out a risk assessment of check dams under extreme precipitation conditions in Ningxia through data collection, hydrological statistics, numerical simulation, and other methods. The conclusions are the following: (1) By the end of 2020, about 40% of the silt reservoir capacity of check dams in various water and soil conservation zones in Ningxia has been accumulated. During 1966–2020, the extreme precipitation and frequency of extreme precipitation in Ningxia increased while the intensity of extreme precipitation decreased. The extreme precipitation in Ningxia increased year by year and lasted longer. (2) Under two future scenarios of RCP4.5 (the full name of RCP is Representative Concentration Pathway) and RCP8.5, the extreme precipitation threshold in Ningxia is gradually decreasing from south to north. Extreme precipitation in the future will bring high risk to the operation of check dams in Ningxia. The results of this paper can provide a scientific basis for the operation and management of check dams in Ningxia.

Voluntary conservation practice adoption is a key strategy to reduce the transport of non-point source pollutants from agricultural lands to downstream ecosystems. This study assessed the short-term (1 year) efficacy of conservation practices to reduce non-point source sediment, nutrient, and fecal indicator bacteria (FIB) transport from working agricultural lands on the Mississippi State University campus, Mississippi State, MS, USA. Water quality was monitored at three treatment sites downstream of the critical resource areas, two of which had paired reference locations. All five sites were monitored for one year pre- and post-conservation practice implementation. Downstream treatment sites generally had higher nutrient and sediment concentrations than upstream reference sites. The results confirmed that the total nitrogen (TN) concentration was reduced post implementation at only the treatment site with the smallest catchment area (p < 0.01). Water quality impairments from FIB were observed across all sites, while treatment locations with livestock presence were found to have significantly elevated staphylococci and E. coli levels following the conservation practice implementation during the winter period. The results of this study showed minimal improvements to TN transport, and in some cases declines in water quality evidenced by increases in FIB, one year after conservation practice implementation. The implementation of conservation practices did not improve the overall water quality to reference levels in the short-term, despite anticipated long-term benefits.

Published: January 2024

Drought refers to a meteorological disaster that results in insufficient soil moisture due to a long-term lack of rainfall and disrupts the moisture balance of crops. Yinshanbeilu in Inner Mongolia is an arid and semi-arid region, and the onset of drought and its subsequent transmission is a key challenge in water resource management. This study takes Yinshanbeilu as the study area, analyses the changing characteristics of multi-timescale drought from 1971 to 2020 based on the Standardised Precipitation Index (SPI), and analyses the stochasticity and stability of the drought by using a cloud model. Finally, the cross-wavelet transform method and Pearson’s test are used to explore the correlation between atmospheric circulation factors, PRE and PET, and drought. The results indicate that (1) on the annual scale, the frequency of drought in Yinshanbeilu mainly ranges from 22% to 28%, with a high frequency of light droughts, a low frequency of severe droughts, a high frequency of droughts in the east and west, and a low frequency of droughts in the north and south; on the seasonal scale, the frequency of droughts in winter is the highest, with a rate of 34.6%, and the lowest frequency of droughts is in autumn, with a rate of 28.3%. (2) There is a decreasing trend in Entropy (En) and Hyper-Entropy (He), and an increasing trend in Expectation (Ex) for the inter-annual SPI-12 cloud model. Spatially, Ex and He are negatively correlated, while En and He are positively correlated. The inter-annual variation in cloud eigenvalues is greater than the inter-site variation, so the cloud model better reflects the spatial stochasticity and stability of regional inter-annual SPI. For the seasonal-scale SPI-3 cloud model, Ex is smaller in all seasons, En is also smaller, and He is larger. (3) Sunspot, PRE (precipitation), and PET (Potential Evapotranspiration) are all positively correlated with SPI and have the highest correlation. This study reveals the characteristics and causes of variations of drought in Yinshanbeilu, which can be applied to future research areas related to regional drought risk management.

Sheep meat is a valuable product that is in great demand on the world market. It is known that lamb has high nutritional and taste qualities. In terms of protein content, it is close to beef, and superior to pork. At the same time, the calorie content of lamb is higher than that of beef. The purpose of the work was to study the production and biological value of meat from young sheep of different breeds in various breeding zones of the Middle Volga region. Under the conditions of the forest-steppe and steppe natural-climatic zones of the Saratov region, a comparative study of indicators of meat productivity and biological value of meat of young sheep of diff erent breeds were carried out such as Volgograd, Tsigai and Edilbaevskaya. Experimental groups in each breed were formed simultaneouslyin both natural zones under identical conditions. It has been established that it is more economically profi table to rear young animals of Volgograd breed in the steppe natural zone. Thus, at the age of 4 months the level of profitability was 44,4 abs.% higher than in the forest-steppe zone, and at 7 months of age by 37,9 abs.% higher than during the slaughter of herdmates from the forest-steppe natural zone. The slaughter of Tsigai breed rams is more profi table in the forest-steppe zone. Thus, at the age of 4 months the level of profi tability was 3,0 times higher, and at 7 months in 3,9 times higher than that of herdmates from the steppe zone. With more profi table production the lamb of Tsigai sheep had a higher biological value. When producing lamb of Edilbaevskaya breed, it is advisable to slaughter young animals at 4 months of age regardless of the zone of their rearing and it is economically profi table to slaughter young animals at the age of 7 months in the steppe natural zone where the level of profitability was higher by 10,5 abs.%.

The purpose of the research was to characterize the pedigree herds of the breeding type of Yorkshire pigs being created based on new lines. An analysis of the results of assessing the adaptive capacity of pigs and the productive traits of animals of various lines bred in breeding enterprises of the Republic of Belarus has been presented in the article. The research used breeding and animal science methods. At the fi rst stage, the “adaptation level” index of sows was determined based on the life expectancy of the sow and its breeding use. At the second stage of the research, young animals of various lines were assessed for their own productivity according to the following indicators such as age of reaching live weight of 100 kg, average daily gain from birth to reaching live weight of 100 kg, lifetime meat traits: thickness of back fat, height of the longissimus dorsi muscle, meat content in the body, using the Piglog-105 device (SFK Technology A/S, Denmark). When analyzing the reproductive traits of sows, we took into account such indicators as prolifi cacy (number of piglets at birth), milk production (litter weight at 21 days), litter weight at weaning at 28 days, and livability of the piglets. As a result of the research, the adaptive ability of sows was determined. An assessment of breeding young pigs in terms of lines showed that young animals of the lines Dixon 4988 and Dania 7723 were distinguished by the best age of reaching 100 kg of live weight and the average daily gain from birth to reaching the weight of 100 kg at the level of 150,8–159,6 days and 685–710 g. In animals of other lines, early maturity was lower by 8,7–30,9 days or 5,17–17,0 % (p ≤ 0,001). A similar trend remained in the average daily gain in live weight. It has been established that the largest value for prolifi cacy was 13,9–15,1 heads per farrowing was observed in sows belonging to the lines Dania 7723 and Dixon 4988. In sows of other lines, the rate was lower by 1,4–3,1 heads or 11,2–25,8 % (p ≤ 0,05). High milk production was detected in sows of the lines Dixon 4988 and Reichil 5507 (64,8–65,6 kg), which was 0,4–7,4 kg or 0,62–12,7 % (p ≤ 0,01) higher than in animals of other lines. The best livability rate was found in sows of the lines Dobry 2313 and Reichil 5507, which was 1,0–4,1 abs.% higher than in sows of other lines.

The Influence of Intrinsic Factors on Personal Attitude to Start a Farming Business: The Moderating Role of Gender
Authors: Mavhungu Mbulaheni , Dhiwayo Sheperd
Published: January 2024

Objective: The aim of this study was to determine the influence of intrinsic factors (proactiveness, motivation, creativity) on the personal attitude of agricultural students to start a farming business in South Africa. This relationship was looked at from gender perspective. Research Design & Methods: An estimated 3,486 students were enrolled for various agriculture-related qualifications in various 27 institutions of higher learning in South Africa when this cross-sectional, quantitative study was carried out. Data from 421 agricultural students were collected through a Prospective Farmers Profile Questionnaire at six institutions of higher learning in South Africa. Findings: The study finds no significant gender influence on all intrinsic factors and also on the personal attitude of agricultural students to start a farming business. The results further revealed that personal attitude to start a business is predicted by intrinsic factors, motivation, and creativity, but not proactiveness. Implications and Recommendations: Entrepreneurial syllabi should aim to equip students with intrinsic factors as these shape the personal attitude to start a business. It is a positive personal attitude that will likely result in a start-up. Farming entrepreneurship, especially among the youth will assist in employment creation as well as food security, two problems that many countries are currently facing. Contribution & Value Added: Proactiveness is one of the most important dimensions of entrepreneurship but agricultural students do not consider it significant in their personal attitude to start a business. Proactiveness should be built into the syllabi for students to be better acquainted with this critical business start-up element.

A Study on Manufacturer’s Order Allocation and Knowledge Sharing Between Suppliers
Authors:   Society for Standards, Certification and Safety, Jeong Dawoon , Park Soohoon , Kim Bosung
Published: January 2024

Although the effectiveness of supplier-supplier knowledge sharing is widely known through the evidence from previous research and Japanese automotive industry practice, it is inherently challenging for potential competitors, i.e., the suppliers, within the supply chain to share knowledge resources voluntarily. Hence, it requires proactive efforts from the manufacturer to facilitate knowledge sharing between suppliers and bring the desirable results to fruition. This study considers the order allocation policy design as the manufacturer's instrument for inducing knowledge sharing between suppliers. Contrary to the previous research, which assumes the mutual reciprocity of supplier-supplier knowledge sharing, this present study contemplates the potential emergence of opportunistic behaviors. We set a model of a buyer-led triadic supply chain and derive the subgame perfect equilibrium by using the mathematical model analysis based on the game theory. The results show that the manufacturer's order allocation policy can affect whether knowledge sharing between suppliers occurs and, if so, the form it takes. Specifically, supplier-supplier knowledge sharing can be induced when the associated level of burden, such as initial investment or potential risk of unintended knowledge leakage, is affordable. Under the medium level of burden, unilateral knowledge provision may occur, and an opportunistic supplier who does not contribute to the communal pool of knowledge resources can be a beneficiary of such a situation. When the burden is at a low level, it is likely that both suppliers readily participate in knowledge sharing and seek mutual capability improvement. Finally, an increment in the effectiveness positively affects the facilitation of knowledge sharing between suppliers.

This study investigated the performance evaluation factors for the fiber filtration process in water treatment and researched the performance evaluation items and methods for assessing these factors. South Korea's water supply and sewage policies focus on modernizing civil structures and networks and introducing advanced treatment facilities. Reflecting these policies, the Waterworks Act describes the minimum requirements that water supply facilities must meet to ensure a consistent quality (water quality) of drinking water. Therefore, the Waterworks Act has introduced usage standards for water treatment processes and materials for water supply to manage the quality of drinking water. Firstly, the Ministry of Environment has issued water supply facility standards, which explain the minimum standards for water supply facilities. Secondly, there are hygiene and safety standards (suitability certification) and group standard certification. Standards and certifications are established to evaluate materials and products suitable for water supply facilities. Thus, two criteria are required to apply them to water supply facilities.
In Republic of Korea, a new concept of water treatment process has been developed that can replace traditional water treatment processes. This involves a fiber filtration process that contracts and relaxes fiber strands, removing turbidity and suspended solids. There is a movement to adopt this process. Such fiber filters can provide better treatment efficiency, use smaller sites, and have faster processing speeds. However, the use of different evaluation methods by manufacturers has prevented consumers from accurately understanding the performance and raised doubts about the reliability of the technology.
The result of this study is the development of a standardized performance evaluation method, and the derivation of performance evaluation factors for fiber filters. Through standardized performance evaluation factors and methods, an objective performance evaluation of the fiber filtration process can be conducted.
THE TOPONYMIC ELEMENT “-END” IN THE ENGLISH-LANGUAGE “ESTATE” THESAURUS: SEMANTICS AND FUNCTION (English-Russian context)
Authors: Veligorsky Georgy A.
Published: January 2024

The article is devoted to the analysis of the history of the toponymic element “-end”, appearing in the names of many estates, both real (for example, the place Dichende in Northumberland, the village of Bourne End in Buckinghamshire, etc.), and literary ones (for example, Freeman’s End from the novel “Middlemarch, A Study of Provincial Life” by George Eliot (1871–1872), Howards End from the novel of the same name by Edward Morgan Forster (1910), Mole End from “The Wind in the Willows” (1908) by Kenneth Grahame, Bag End from John Ronald Reuel Tolkien’s fantasy novel “The Hobbit, or There and Back Again” (1937), etc.). Attention in the study is paid to non-obvious, “latentˮ, including metaphysical, connotations of this concept (house “on the outskirts”, “dead end”, “goal”, “appointment”, etc.). The article specifically considers the genesis of the “-end” element, which goes deep into the history of the English estate (in particular, it is mentioned in the “Domesday Book”, the first land census of England, undertaken in the 11th century by William the Conqueror).
LITERARY WAYS OF CYCLISATION IN MODERN ROCK POETRY (based on the album “Creativity in the Void” by the “DDT”)
Authors: Belyaeva Natalya P.
Published: January 2024

This article is intended to concretise the methods of cyclisation in the album “Creativity in the Voidˮ of the “DDTˮ, the presence of which indicates the integrity of the musical collection of it. The real goal dictates the solution of several research tasks, including the theoretical substantiation of cyclisation as a scientific problem in the study of rock poetry, the identification of the characteristic features of cyclisation inherent in the poetry of rock performers, and the analysis of the logic of building the album “Creativity in the Voidˮ of the rock band “DDT”. When performing the work, analytical methods of research, synthesis and comparison were applied, sociocultural and some biographical factors were considered, which makes it possible to reveal the philosophical and aesthetic meanings inherent in the single artistic space of the collection as a “product” of cyclisation. The author of this article concludes that the phenomenon of cyclisation is inherent in the work of the rock band “DDT”. The non-randomness of the arrangement of texts in the structure of the album has an impact on the interpretation of the picture of the world of the poet Yuri Shevchuk, which is artistically explicated in the musical works included in the framework of a separate album. The conclusions of the study make a certain contribution to the development of ideas about the artistic originality of the named musical band, expand the understanding of the phenomenon of cyclisation, including metacyclisation, in the work of rock performers in general.
TSARITSYN, STALINGRAD, VOLGOGRAD GODONYMS AS THE REFLECTION OF THE TWENTIETH CENTURY HISTORICAL PROCESSES
Authors: Antonenko Natalia S. , Ilyin Dmitriy Yu.
Published: January 2024

Godonyms as the road network elements nominations are a kind of the urban environment text that is able to record various phenomena of the surrounding reality. The article analyzes the renaming and changing the nominations of the address-forming elements of Tsaritsyn, Stalingrad and Volgograd. Such transformations reflect the socio-political and social processes that have taken place in different historical periods. Linear objects, whose nominations were changed from one to four times, were identified during the comparing cartographic and other sources of 1914, 1925, 1942, 1959 and 2022. The reasons and catalyst for this process were extralinguistic: the October Revolution, the city destruction during the Battle of Stalingrad and its further rebuilding. The ideological grounds for renaming are relevant for all the city development stages. These reasons manifest themselves the most clearly when the nominations are changed between 1914 and 1925, as well as 1925 and 1942. After 1942, the number of renames is significantly reduced. The reason of this is the restoration of buildings that were almost totally destroyed during the Battle of Stalingrad and assignation to the linear objects the same names as before the Great Patriotic War. The exceptions are hodonyms that perpetuate the military formations and military leaders memory who participated in the defense of the city.

Authors:   Korean Lesson Study Group for Social Studies, Yu Jong Youl
Published: January 2024

The purpose of this study is to analyze the characteristics of the training program developed to enhance the democratic citizenship education competence of low-experienced social studies teachers through discussion and debate, and to derive implications for the development and implementation of teacher training programs for low-experienced teachers in the future. To this end, the analysis focused on the training program development process and content structure, and the responses of training participants. As a result of the analysis, the teachers who participated in the training gave a very positive evaluation of the training program. Not only was the satisfaction with the content and method of the lecture very high, but it was also highly evaluated in terms of its usability in work. The training instructors recognized that the logical arrangement of the training program was outstanding and that the satisfaction of training participants was high due to the training program being structured around activities and participation. However, they evaluated that the lack of training time, the lack of understanding of the participants’ needs and demands, and level difference between programs(courses) by the instructors’ individual capabilities needed to be improved. Based on these analysis results, field orientation, integration, and cooperation were presented as principles of improving the training system for low-experience social studies teachers and suggested implications for the development and operation of training programs based on this.
Design and Application of Elementary Social Studies Classes to Foster Social Empathy
Authors:   Korean Lesson Study Group for Social Studies, Han Seong Beom
Published: January 2024

Modern society is living in an era of "unsympathetic" that has become insensitive to other people's senses. Therefore, this study proposes empathy-based social studies classes to cultivate students' social empathy skills based on the need for social empathy and to change students' cognitive, behavioral, and affective aspects. In particular, the approach to social empathy beyond personal empathy can lead to a three-dimensional and multifaceted approach to unequal social structures and vulnerable groups in marginalized societies beyond the level of understanding and consideration for others. This study ultimately aims to cultivate the proper social empathy ability to comprehensively understand the characteristics of society and develop the qualities of a democratic empathy citizen who creatively and reasonably solve modern society's problems. Accordingly, the elementary social studies curriculum was analyzed, and social studies classes were organized and implemented for fifth-grade students based on a social empathy-based model. After applying social studies classes, quantitative analysis was conducted through a paired sample t-test to measure the cultivation of students' social empathy skills. In addition, students' cognitive, affective, and behavioral changes were observed and analyzed using methods such as pre- and post-test papers, impressions, diaries, class observations, and in-depth interviews. Based on quantitative and qualitative analysis, students were able to develop social empathy skills through this class, and it was confirmed that there were positive changes in cognitive, emotional, and behavioral aspects.
