The Spread of Tibetan Buddhism in Mongolia from the 16th to the 17th Century: The Spatial Formation of the World Heritage Site Erdene Zuu Monastery

Erdene Zuu is the oldest extant Buddhist temple in the country of Mongolia, founded following the reintroduction of Tibetan Buddhism to Inner Mongolia in the sixteenth century. The subject of this paper is the building activities of the sixteenth and seventeenth centuries, particularly of the complex centering on Gurban Zuu (Three Temples), which are the main buildings of Erdene Zuu. The author first confirms Gurban Zuu’s ground plan based on measurements, and then interprets the “black-ink inscription” discovered on the ridge purlin of the Central Buddha Hall. This complex is then compared with Inner Mongolian Buddhist temples of the same period. Finally, the author studies whether or not the spatial structure of the temple architecture of the Mongolian Empire of the thirteenth and fourteenth centuries was continued at Erdene Zuu, and analyzes the position that Erdene Zuu occupied in the Tibetan Buddhist sphere. This comparative study investigates the origins of Erdene Zuu’s architectural spatial composition within East Asia.

Paradoxes of Historical Consciousness in Ulaanbaatar Monumental Sculpture. Ideological Function of Monuments in the Context of “Mongolian National Revival” in the 21st Сentury

This article deals with Ulaanbaatar monumental sculptures which have been produced during the course of the last 20 years. It studies various processes typical of the socio-political and cultural life of present-day Mongolia that impressed greatly content as well as style of many monuments erected in honor of the outstanding leaders of this country. The core idea of these artworks consists in developing the concept of the national identity which became characteristic of the spiritual life of Mongolia after the Democratic Revolution of 1990. In its turn, this concept is based on specific interpretation of Mongolia’s historical past which is focused on the figure of Chingis khan as an embodiment of the national idea. The establishment of his cult in the democratic country with market economy forms an essential element in the process designated in this article as “Mongolian national revival”. Within the general framework of the state cultural policy, this tendency found its expression in erecting a wide range of various monuments dedicated to the Great Khan as well as other rulers of mediaeval Mongolia. On the other hand, it’s also evident that this policy implies an idea of historical continuity that provides a link between different epochs of Mongolian history. This leads to the conclusion that Communist leaders of the People’s Republic of Mongolia are nowadays considered as the true hears of the mediaeval rulers of the country because they also contributed to the Mongolian civilization building. This article demonstrates what kind of artistic means have been implemented in solving this task. One of the major concerns consisted in involving the viewer in comprehending meaning of the monuments. This stimulated the emergence of the new and highly innovative artistic typology of the monumental-didactic sculptural ensemble exemplified in the monument to the singer S. Tsogtsaihan.

Борхын голын залгаа гурван хэрэм

The wall is located in Aldarkhaan sum of Zavkhan province. In 1961, Kh.Perley made a general mention of the wall in his work “Early and muddle period urban settlements of the People’s republic of Mongolia”, and it has not been specifically studied until now. As a researcher, I visited the wall in 2020 and did the first round of documentation, and then 2021, 2022 and 2023, I went back with researchers to make detailed survey, aerograph, background photos and sample survey. The above wall is related to the Manchurian period and it’s quite possible that there are ruins of an ancient city at the bottom of the wall after conducting detailed excavation research.

몽골 문화유산 보호 법체계 변화 연구

One of the advantages of Mongolia’s implementation of a comprehensive policy on cultural heritage preservation and protection since 1921 is the establishment of legal regulations.
 The first legal act related to preservation and protection of cultural heritage is “Regulations on Preservation of Antiquities” was approved on September 5, 1924 with 10 articles, which covered the jurisdiction of ownership of cultural heritage, items included in cultural heritage, their study, preservation, protection, regulations on use, control, and responsibility are included.
 After that, on November 13, 1941, in connection with the current situation, the previous 1924 rule was added and approved as a same name “Rule for the Preservation of Antiquities” with 10 articles. Provisions relating to ownership, preservation, protection, use, and control are included in this 1941 regulation, similar to the previous regulation approved in 1924. However, with this regulation, for the first time, cultural heritages were ranked, along with a list of cultural heritage to be protected by the state.
 On October 12, 1970, 30 years after the adoption of the 1941 regulation, the “Law on the Protection of Cultural heritages of the People’s Republic of Mongolia” consisting of 4 chapters and 20 articles was approved for the first time. The law regulates the definition, ownership, classification and scope of cultural heritages, monitoring of research, collection, preservation, and use activities, as well as responsibilities for violators of the law. However, the list of monuments to be protected by the state and the level of cultural heritage included in the previous rules are not included.

Cryo‐Electron Tomography of Highly Deformable and Adherent Solid‐Electrolyte Interphase Exoskeleton in Li‐Metal Batteries with Ether‐Based Electrolyte (Adv. Mater. 13/2022)

Solid Electrolyte Interphase The solid electrolyte interphase (SEI) plays a critical role in determining the cycling stability of lithium-metal anodes. However, viewing the SEI in batteries remains extremely challenging due to its supersensitivity to the electron beam under a microscope. In article number 2108252, Ju Li, Meng Gu, and co-workers develop an ultralow-dosage cryo-TEM protocol to directly visualize the SEI in 3D at different charging states, revealing surprising and fundamentally significant results for the SEI. The optimized chemo-mechanical properties of the SEI contribute significantly to the superior performances of Li-metal batteries.

Comparative Assessment of Grassland Dynamic and Its Response to Drought Based on Multi-Index in the Mongolian Plateau.

This study applied grassland related multi-index and assessed the effects of climate change by investigating grassland responses to drought. This process was performed to study grassland vegetation dynamic accurately and evaluate the effect of drought in the Mongolian Plateau (MP). The spatial–temporal characteristics of grassland dynamic in terms of coverage (Fv), surface bareness (Fb), and net primary production (NPP) from 2000 to 2013 were explored. We implemented the maximum Pearson correlation to analyze the grassland vegetation in response to drought by using self-calibrating Palmer Drought Severity Index (scPDSI). Results show that Fv and NPP present an increasing trend (0.18 vs. 0.43). Fb showed a decreasing trend with a value of −0.16. The grassland Fv and NPP positively correlated with scPDSI, with a value of 0.12 and 0.85, respectively, and Fb was −0.08. The positive correlation between Fv and NPP accounted for 84.08%, and the positive correlation between Fv and scPDSI accounted for 93.88%. On the contrary, the area with a negative correlation between Fb and scPDSI was 57.43%. The grassland in the MP showed a recovery tendency. The increase in grassland caused by positive reaction was mainly distributed in the middle of Mongolia (MG), whereas that caused by counter response was mainly distributed in the east and west MG and northeast Inner Mongolia autonomous region of China (IM). The relevant results may provide useful information for policymakers about mitigation strategies against the inverse effects of drought on grassland and help to ease the losses caused by drought.

THE GRAVITATIONAL MODEL OF THE MONGOLIAN FOREIGN TRADE

The article presents an analysis of Mongolia's foreign trade using econometric gravity modeling tools as a popular tool for analyzing international trade flows. To create a model for the development of the Mongolian economy in the context of modern globalization processes, the authors studied exogenous and endogenous models of economic growth. To develop the gravity model of the Mongolian Economy, the current state of Mongolia’s foreign trade was studied in the context of the economic situation of the 10 countries of Mongolia’s trading partners that most strongly influence the gross trade of Mongolia. The statistics of the Customs Administration and the National Statistical Committee of Mongolia are used, as well as macroeconomic indicators of the countries of the world. When building the model, the main assumptions of the gravitational theory were used, that trade flows positively depend on the size of the GDP of the countries of foreign trade partners, therefore, for the regression analysis, the GDP sizes of 10 active partners of Mongolia are taken. Alternative methods of resistance to foreign trade are also considered, in particular the distance indicator.

Risk Factors for Cerebral Aneurysm Rupture in Mongolia

PurposeIdentification of country-specific demographic, medical, lifestyle, and geoenvironmental risk factors for cerebral aneurysm rupture in the developing Asian country of Mongolia. First-time estimation of the crude national incidence of aneurysmal subarachnoid hemorrhage (aSAH).MethodsA retrospective analysis of all intracranial digital subtraction angiographies (DSA) acquired in Mongolia during the 2‑year period 2016–2017 (1714 examinations) was performed. During this period, DSA was used as primary diagnostic imaging modality for acute severe neurological symptoms in the sole hospital nationwide dedicated to neurological patients. The catchment area of the hospital included the whole country. Patients with incidental and ruptured aneurysms were reviewed with respect to their medical history and living conditions. The data was used to install a Mongolian aneurysm registry.ResultsThe estimated annual crude incidence of cerebral aneurysm rupture was 6.71 for the country of Mongolia and 14.53 per 100,000 persons for the capital region of Ulaanbaatar. Risk factors common in developed countries also applied for the Mongolian population: A medical history of hypertension, smoking or the presence of multiple aneurysms led to a higher relative risk of rupture. In contrast, female gender was not associated with a higher risk in this national cohort. Males pursuing a traditional nomadic living may exhibit a specifically high risk of rupture.ConclusionDisease management of over 200 individuals/year with aSAH constitutes a socioeconomic burden in Mongolia. Efforts to raise awareness of the risk factors hypertension and smoking among the Mongolian population are desirable. Measures to improve the nationwide availability of modern neurovascular treatment options are currently under consideration.

Excavation of Genes Related to the Mining of Growth, Development, and Meat Quality of Two Crossbred Sheep Populations Based on Comparative Transcriptomes.

Simple SummaryIn this study, we measured the performance parameters of two crossbred sheep breeds, using Masson staining of the muscle tissue, and using the Illumina high-throughput sequencing platform to determine the differentially expressed genes (DEGs) in Dorper (DP) × Small-tailed Han (STH) sheep and Mongolia (MG) × Small-tailed Han sheep (STH). New transcripts of the muscle transcriptome were examined for the first time. DP × STH sheep were superior to MG × STH sheep in terms of meat quality and muscle morphology. In addition, 13 DEGs were found to play important roles in growth, development, and meat quality. The findings of this work may provide valuable resources for future research on muscle development in sheep.Crossbreeding can improve production performance and meat quality in sheep. The objective of this study was to look for genes related to sheep growth, development, and muscle. In this study, Dorper (DP) × Small Tailed Han (STH) sheep and Mongolia (MG) × Small-tailed Han (STH) sheep were used to estimate the productive performance and meat quality in a crossbreed. Subsequently, transcriptome analysis and bioinformatic analysis were performed on the Longissimus dorsi muscles of DP × STH and MG × STH sheep to identify differentially expressed genes (DEGs) related to growth, development, and meat quality. The presence of DEGs was confirmed by real-time PCR (qPCR). Productive performance and meat quality of the DP × STH sheep were better than the MG × STH sheep. Compared to DP × STH, a total of 1445 DEGs were identified in MG × STH sheep (1026 DEG were up-regulated and 419 DEG were down-regulated). Of these, 38 DEGs were related to growth, 161 to development, and 43 to muscle. In addition, 13 co-expressed genes (FGFRL1, SIX1, PLCB1, CRYAB, MYL2, ADIPOQ, GPX1, PPARD, GPC1, CDC42, LOC101106246, IGF1, and LARGE) were identified. The expression of DEGs was consistent with the comparative transcriptome analysis. This work provides genetics resources for future research on muscle development in sheep.

Mongolian-Russian diplomatic relations: history and prospects

The article deals with the history and prospects of the development of diplomatic relations between Mongolia and Russia. It is noted that diplomatic relations between the two states have a long history. The author identifies three main stages in the development of diplomatic relations between the two countries. The first stage was the Soviet one (until 1991). It was during this period that the foundations of cooperation between the two states were laid. At the same time, diplomatic relations were supported by broad cooperation in the economic and military-political spheres. Mongolia and Russia have been acting as allies for a long time. At the same time, the USSR acted as a guarantor of Mongolia's independence. The second stage (1991–2000) is characterized by the cooling of bilateral relations, which was due to the processes that took place in the USSR. The third stage (2000 and up to the present) is characterized by the intensification of diplomatic contacts. This is reflected in the frequency of official visits of the heads of state of Mongolia and Russia, as well as heads of diplomatic departments of Mongolia and Russia. The period of the 2000s. it is characterized by the presence of permanent diplomatic contacts between Mongolia and Russia. Their results are expressed in a number of declarations and agreements on cooperation between countries in various fields. Cross-border cooperation is also actively developing. The author notes that the prospects for further development of diplomatic relations between Mongolia and Russia are dictated by the goals of the foreign policy of both countries. The author notes that Mongolia is characterized by the desire to build equally equal relations with all states. Russia, on the contrary, seeks to build cooperation by attracting new member states to interstate associations of various directions. In particular, Russian diplomacy is making efforts to attract Mongolia to participate in the processes taking place within the framework of Eurasian integration. At the same time, the further development of cooperation is considered by the Russian side from the point of view of deepening the processes of Eurasian integration. At the same time, the Mongolian side, in accordance with the provisions of its foreign policy concept, does not seek to join any political associations. The author concludes that considering the prospects for further development of diplomatic relations between Mongolia and Russia, it is necessary to take into account the differences in approaches to the implementation of foreign policy between the two countries.

Obesity and associated factors among students in Inner Mongolia in 2019

Objective To understand the prevalence of obesity and its associations with diet, exercise and mental health among students in Inner Mongolia, so as to provide scientific basis for the formulation of obesity intervention measures for students in this area.

Conclusion The overall obesity rate of students in Inner Mongolia is relatively high, and the occurrence of obesity is related to diet, exercise behavior, living habits and psychological factors. 【摘要】 目的 了解内蒙古地区学生肥胖现状及其与饮食、运动、心理等方面的关系, 为制定该地区学生肥胖干预措施提 供科学依据。 方法 采用分层整群随机抽样方法, 抽取内蒙古自治区全部12个盟市、103个旗县区的186 649名学生。按 中国学龄儿童青少年超重与肥胖筛査标准对调査对象进行分组, 采用妒检验进行单因素分析, 采用多因素非条件Logistic 回归模型筛选肥胖有关因素。 结果 学生总体肥胖率为18.54%, 男生肥胖率为22.04%, 女生为14.99%。多因素Logistic 回归分析结果显示, 监测点 ( OR = 0.79)、性别 ( OR = 0.61)、每日吃油炸食品次数 ( OR =1.08)、每周每日运动超过60 min>2 d ( OR = 0.89)、是否每天吃早餐 ( OR = 0.86)、每日喝饮料次数 ( OR = 1.12)、吸烟 ( OR = 0.87)、饮酒 ( OR = 1.07)、每日吃水果次 数 ( OR =1.07)、每日看电视 ≥2 h ( OR =1.06)、睡眠时间 ( OR = 0.93)以及学段可能与学生肥胖有关 ( P值均<0.05)。 结论 内蒙古地区学生总体肥胖率较髙, 学生肥胖的发生与饮食运动行为、生活习惯及心理因素有关。应采取针对性干预措施控 制学生肥胖的发生。

Characteristics and environmental driving factors of water transformation in the Balaguer River watershed of Inner Mongolia steppe.

Inner Mongolian steppe is one of the ecological barriers in China. The variation of water resources is very important for the development of social-economy and the protection of eco-environment. We collected 254 water samples of precipitation, river, and shadow groundwater during wet-season and dry-season of 2018-2019 from Balaguer River watershed and meansured the physical-chemical indicators, δD and δ18O of water samples. The stable isotope technology, mathematical statistics, and the inverse distance weighting method were used to analyze the stable isotope composition, spatial-temporal variation, and impact factors. Moreover, the d-excess and the isotopic mixing ratio formula were used to analyze the conversion characteristics of different water and to identify their environment driving variables. The results showed that δD and δ18O of precipitation, river and shallow groundwater were higher in wet season than in dry season. The driving factors of different water transformation in the watershed were air temperature, altitude, and groundwater depth. Altitude was significantly negatively correlated with river δD, and the δD and δ18O of groundwater. δD and δ18O of groundwater fluctuated significantly in the area with groundwater depth less than 10 m, but were stable in other areas. There was a positive correlation between precipitation δ18O and air temperature. The d-excess in wet season was higher than that in dry season, with a decreasing distribution characteristic from southern to northern part in the study area. More than 50% river in upper stream came from precipitation, while more than half river water converted to groundwater, with different recharge-drainage relationships existed between surface water and groundwater in different river reaches.

Three-decadal destabilization of vegetation activity on the Mongolian Plateau

Steppes on the Mongolian Plateau, mainly within the Republic of Mongolia and the Inner Mongolia Autonomous Region (IMAR) of China, have been subjected to widespread degradation as a result of climate change and human utilization. Field experiments and long-term observations suggest that the productivity of degraded grassland ecosystems might show greater instability, i.e. stronger interannual variation in vegetation activities, when driven by climate change. However, it remains unknown whether this hypothesized destabilization of steppe vegetation activity has occurred in the past three decades and how this destabilization has fed back to livestock production on the plateau. Herein, we define temporal instability of vegetation activity using three indicators, the start and end of the growing season as indicated by the normalized difference vegetation index (NDVI) and the mean growing-season NDVI, and examine their trends between 1983 and 2015. Our results show a significant destabilization of vegetation activity over a large proportion of the total steppe area. Compared with the IMAR, vegetation destabilization has occurred to a significantly higher extent in Mongolia. Climate warming, drying and interannual climate variability accounted for approximately 60%–80% of the vegetation destabilization. The destabilization of steppe productivity was significantly associated with the interannual variability of livestock production in Mongolia, while the interannual variability of steppe productivity and livestock production were decoupled in the IMAR. Our findings highlight the need to improve livestock production systems and conserve degraded grasslands for sustainable development in view of the destabilization of steppe productivity on the Mongolian Plateau.

Spatial heterogeneity of soil heavy metal content in Baiyinhua mining area, Inner Mongolia, China.

To evaluate the spatial distribution characteristics of soil heavy metal content in Xiwuzhumuqin Banner, Inner Mongolia, we analyzed the spatial heterogeneity of soil Cu, Cr, Pb, and Mn contents within 8 km distance of the mining area. Results showed that the contents of Cu, Cr, Pb and Mn in soil were 12.7, 32.6, 29.9 and 201.3 mg·kg-1, and their coefficients of variation were 26.8%, 33.9%, 27.1% and 45.7%, respectively. According to the model fitting by semi-variance function, the spatial distribution of Cu, Cr, Pb and Mn were consistent with the Gaussian model, Gaussian model, Gaussian model and linear model, respectively. Results of the spatial distribution pattern analysis showed that the spatial correlation levels of Mn, Cr and Cu were high, which were mainly affected by structural factors, but little affected by random factors. The spatial correlation level of Pb element was moderate, which was affected by both structural factors and random factors. Results of the fractal dimension analysis showed that the spatial distribution of four heavy metal contents was simple. Combined with 2D and 3D views, the four types of heavy metals all presented gradient distribution, which decreased with the increases of distance. The contents of Cu and Mn were mainly concentrated within 1.5 km from the mining area, while Cr and Pb were mainly concentrated within 2.0 km and 3.0 km from the mining area, respectively.

Impacts of climate change and human activities on net primary productivity of grasslands in Inner Mongolia, China during 1982-2015.

We analyzed the impacts of climate change and human activities on the net primary productivity of grasslands in Inner Mongolia during 1982-2015. The results showed that the growth rates of actual net primary productivity (ANPP) were 1.08 and 1.36 g C · m-2 · a-1 in 1982-1998 and 1999-2015, respectively. Such changes were largely due to restoration, with restoration implementing in 81.6% and 76.3% of the total study area in 1982-1998 and 1999-2015, respectively. The area of degraded grasslands tends to increase. The effects of climate change and human activity varied across different types of grassland. Climate change was the main contributor to grassland restoration over the two periods, with the contribution rates being 79.3% and 94.1%, respectively. The ANPP was positively correlated with precipitation but not with temperature, indicating that precipitation was the main climate factor influencing grassland restoration. Human activities contributed most to grassland degradation over the two periods, with the contribute rate being 83.3% and 87.8%, respectively. Our results suggested that the climate change was the dominant contributor to grassland restoration, while human activities, such as increase in livestock numbers, cultivation and afforestation, accelerated grassland degradation.

Effects of grazing intensities on functional traits of Cleistogenes squarrosa in a typical grassland of Inner Mongolia, China.

We examined the response of 11 functional traits of Cleistogenes squarrosa, including plant height and clump width, to the grazing of different intensity (no grazing; twice grazing in May and July; five grazing in the whole growing season). After five-year treatments, the number of reproductive branches, plant height, stem quality, specific leaf area and total leaf area were significantly reduced. Such reduction was significantly increased with the increases of grazing intensity. Under the treatments of grazing in May and July, the declines of each index were 61.7%, 21.5%, 33.3%, 21.6% and 26.7%, respectively; and the declines in the treatment of whole growing season grazing were 75.7%, 24.7%, 46.7%, 28.5% and 43.7%, respectively. The number of vegetative branches, number of leaf, total leaf area, stem quality, total leaf quality and clump width of the C. squarrosa had a synergistic relationship with aboveground biomass of the whole clump under different grazing intensities. The number of vegetative branches was significantly positively correlated with stem quality and total leaf quality. C. squarrosa had a dwarf-dense branching strategy to avoid grazing. The reduction of grazing intensity would be conducive to maintaining the stability of functional traits.

Variations in Frequency and Intensity of Dust Events Crossing the Mongolia–China Border

In this study, we investigated the spatiotemporal variations of border-crossing dust events (DEs), including floating, blowing dust, and dust storms between Mongolia (MG) and Inner Mongolia (IM), China using the ground-based observations from 91 synoptic stations across the Mongolian Plateau during 1977-2018. We defined the intensity of DEs (progressive and recessive) depending on the dust impact area (number of stations affected by dust) by dividing them into three categories: DEs, transported dust events (T-DEs), and severe transported dust events (ST-DEs). The results revealed that during 1977-2018, the frequency of DEs in MG was two times higher than in IM. Simultaneously, the frequency of DEs (dominated by dust storms) increased in MG, whereas IM experienced a decrease in DEs (prevalent types of blowing dust). The T-DEs occurred 2.4 times higher than the ST-DEs over Mongolian Plateau. For the border-crossing DEs, transported dust storms were the dominant type. During 1977-1999, approximately 86% of DEs in IM originated from MG; however, this was decreased to 60% in the 2000s (2000-2018). The intensity of the border-crossing DEs originated from MG and the recessive T-DEs increased significantly since the 2000s, which were more significant than the progressive type.
