Mongolia is a huge, landlocked, middle-Asian country bordering Russia in the north, and China in the south. Mongolia was under socialism from 1921 to 1990, and its political system has started moving toward capitalistic democratism in 1990. The history of the Mongolian Oral & Maxillofacial Surgery can be divided into four periods; the incipient period($1956{\sim}1971$), the period of early development($1971{\sim}1981$), the period of active development($1981{\sim}1991$), and the period of reformation($1991{\sim}$). Mongolian Oral & Maxillofacial Surgery had been developed by the cooperation of Soviet Union and Eastern European countries before the 1990s, but the role of Korea, Japan, and western countries has been increasing from the 1990s. In Mongolia Oral & Maxillofacial Surgery is well recognized to the people and is considered as one of the specialized medical field. There are specialized departments of Oral & Maxillofacial Surgery in State Central Hospital, Child & Maternal Research and Clinical Center, and Oncology Center in Ulaanbaatar. Now, the basic knowledge and surgical technique of the Mongolian Oral & Maxillofacial Surgeons are satisfactory. But because of the difficult social and economic situation, there is a shortage of surgical instruments and materials, and acquirement of new knowledge is not easy. In 1998 the Mongolian Association of Oral & Maxillofacial Surgeons was established and its members want to have international relationship to keep up with the new medical information. Mongolia and Korea have ethnic, linguistic and cultural similarity, so the interchange and cooperation between Mongolian and Korean Oral & Maxillofacial Surgeons are recommended to make a beautiful one-world.

The purpose of this study is to compare traditional productivity and environmental productivity of Chinese 28 provinces for 1997-2005. The Eastern, the Central and the Western regions show higher M productivity indices than ML productivity indices before 2000 year, but two productivity indices of three regions report almost similar levels after 2000 year. The M productivity indices were higher than the ML productivity indices in the most provinces for 1997-2005. It implies that the Chinese regional economies have difficulties in the production activity reducing pollutants and increasing desirable outputs simultaneously. In the future, the Chinese 28 provinces need to change the direction of economic growth in the way that pursuits economic growth restraining pollution emission quantities thoroughly and should improve the concrete investment for clean technology of pollutant treatment, reinforcement of environmental regulation, and effectiveness of enforcement law.

Dill (Anethum graveolens L.) is an annual herb with a long history and it is mainly used as a spice and as a medicine that is effective as a digestive aid, a sedative, and a narcotic, and that helps remove bad breath. Dill grows wild in the districts along the shores of the Mediterranean Sea, West Asia, China, and Korea. An estimate of the phylogenetic relationships within dill accessions in 20 countries was inferred using data from the rps16-trnK3-intergenic spacer. The aligned data sets for dill ranged from 747 to 779 nucleotides (bp) as a result of the differences in the insert/delete nucleotides. The sequence variation within the dill accessions was mostly due to nucleotide substitutions, although several small insertions and deletions can be found. Among 100 accessions from 20 countries, the Eastern Asia accessions were more closely related to the North American accessions than to the Central Asia and European accessions. Although some accessions were not congruent completely with geographical locations, the dill accessions with rps16-trnK analysis resulted in plants with better-resolved clades.

The modern political scientist Liang, qi-chao (1873-1929), who insisted on the richness of China, was a major axis of Korean intellectuals in the nineteenth century. His patriotism for Chinese reconstruction oppressed by Western powers has greatly influenced Korea 's will to build a modern nation. There was military power and physical education at the center of Liang, qi-chao thought. He emphasized military strength through military strength with a strong stamina, so he mentioned the necessity of military and physical education. Based on the idea of this kind of Liang, qi-chao, the korean intellectuals believed that the Korean people should be born healthy through physical education. The initial introduction of physical education in Korea was integrated with the Military Sports. For the first time, Being introduced Western Sports in 1895, The fact that the army athletic gymnastics was first introduced into school education in 1896 proves this oneness. Moreover, Ethnic scholars continued to focus on fostering strong nationality through physical education based on the spirit of Liang, qi-chao, and was emphasizing the gymnastics of the military sportsman at the central idea.

This study examined the factors that influence the emotional expression in comments on the hot news about the 'Restaurant Collapse in Linfen City, Shanxi Province' published in Sina Weibo.. As a result of the study, first, there were differences in emotional expression according to gender. Women expressed stronger anger, disappointment, sadness, and condemnation than men. Second, the intensity of emotional expression of users in the eastern region was significantly higher than that of users in the central and western region. Third, the greater the number of Weibo, the total number of blogs where users participated in comments and posted emotional expressions, the stronger the emotional expression was. Fourth, unauthenticated users showed stronger emotional expressions of disappointment and sadness than authenticated users. The results of this study present implications for the factors influencing emotional expression on hot news. This study is meaningful in that it can be compared with social networks such as Twitter and Facebook in the West by looking at the factors that influence emotional expression in the process of online public opinion formation in China, and also meaningful in that a big data analysis method was used in online news analysis.

Objectives: To compare Korean medicine (KM) and traditional Chinese medicine (TCM) psychotherapy for anxiety. Methods: Databases including MEDLINE (via PubMed), EMBASE (via Elsevier), Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Oriental Medicine Advanced Searching Integrated System were comprehensively searched. Prospective clinical studies on KM or TCM psychotherapy for patients with anxiety disorder or individuals with elevated anxiety levels published up to August 3, 2022 were reviewed. Psychotherapy was divided into counselling, art therapy, and meditation according to its characteristics. Results: A total of 12 clinical studies were reviewed, including nine randomized controlled trials. The most common disorder investigated was post-traumatic stress disorder. Ten studies used TCM psychotherapy and two used KM psychotherapy. As for differences between TCM psychotherapy and KM psychotherapy, TCM psychotherapy utilized pattern identification in the procedure more actively than KM psychotherapy. In addition, some TCM studies have attempted to directly converge Western psychotherapy (i.e., hypnosis) and Eastern psychotherapy (i.e., Taoin qigong therapy). In the case of KM psychotherapy, there was an attempt to incorporate psychotherapy with Sasang constitutional medicine. Reported effects of TCM psychotherapy and KM psychotherapy on anxiety were positive. Conclusions: Research status of KM psychotherapy and TCM psychotherapy for anxiety was investigated, revealing some of their characteristics, commonalities, and differences. Findings of this review have the potential to provide a clue to the development of conventional KM psychotherapy and new medical technology for KM psychotherapy.

This study examines the process of the introduction of stupa, which has originated in India, to the Xinjiang Uyghur region and the features of the stupas in the Xinjiang Uyghur region in detail. This study examines the layout of the buildings in temple compounds and the types, structural elements, and construction methods of the stupas in the Xinjiang Uyghur region in particular by looking into the content of the Da Tang Xi Yu Ji and remaining stupas, which provide examples of stupas at the time. This study finds that due to the characteristics of dry deserts, stupas in Xinjiang Uyghur region, where assimilation between Eastern and Western cultures is seen, were mostly made by pressing clay into a mold and had no interior spaces. Also, construction materials and techniques had been developed and improved in a way that enabled stupas to combat the challenging desert conditions. However, the stupas in this region differed significantly from the wooden tower-like stupas discovered in central China(zhongyuan 中原). The shape of the dome of most stupas in Xinjiang Uyghur region was chosen under the influence of the Gandharan style. Some of the stupas in the region have taken the general forms of the wooden stupas and the others have taken many forms, from cylindrical drums to towers. Also, there have been forests of stupas and stupas similar in form to chaityas and stupas of Vajrayana. Such different forms were transformed and modified through regional history and it was related to the peoples and cultures that produced and used stupas. Stupas evolved into distinct forms in Xinjiang Uyghur region in this way.

The Quercus variabilis and Quercus dentata, which are said to be relatively drought tolerant among the important genus Quercus that represent deciduous broad-leaved forests in Korea. These two species are widely distributed worldwide in Korea, Japan and China (northern, central, western and eastern subtropical regions). This study compared the ecological niche breadth and overlap according to growth response in 4 soil moisture gradients for the two species and tried to reveal degree of competition and ecological niche characteristics. The ecological niche breadth was 0.977±0.020 for Q. variabilis and 0.979±0.014 for Q. dentata, the latter being slightly wider. And they were similar in 5 traits (stem length, leaf lamina length, leaf width length, stem weight, leaf petiole weight), Q. variabilis was more dominant in 4 traits (leaves number, stem diameter, leaf area, leaf petiole length), and Q. dentata was more dominant in 7 traits (root length, shoot length, plant weight, root weight, shoot weight, leaf weight, leaf petiole weight). The ecological niche overlap for soil moisture between the two species overlapped most in plant structure-related traits and least in photosynthetic organ-related traits such as petiole length. As a result of principal component analysis, degree of competition between the two species for soil moisture was more severe when the soil moisture condition was low than high. Among the measured traits that affect the two-dimensional distribution, 8 traits (Leaves number, Shoot length, Stem length, Plant weight, Root weight, Shoot weight, Stem weight, Leaves weight) were correlated with the factor 1, and 2 traits (Leaf width length, Leaf petiole weight) were correlated with the factor 2 (r>0.5). These results show that the ecological response of the two species to soil moisture is not a few traits involved, but several traits are involved simultaneously.

The wintertime upwind flow in the Yellow Sea has been investigated through a series of two-dimensional numerical experiments in an idealized basin. A total of 10 experiments have been carried out to examine the effects of wind forcing, bottom friction and the presence of oceanic currents sweeping the shelf of the East China Sea. A spatially uniform steady and periodic wind stresses are considered along with comparison of linear and quadratic formulations. The wind-driven flow in the absence of oceanic current has been computed using Proudman open boundary condition (POBC), while the wind-driven current in the presence of oceanic current has been computed using Flather’s radiation condition (FOBC). The oceanic currents to be prescribed at the open boundary have been simulated by specifying uniform sea level gradients across the Taiwan Strait and the eastern ECS shelf, Calculations show that, as seen in Lee et al. (2000), oceanic flow little penetrates into the Yellow Sea in the absence of wind forcing unless a unrealistically low rate of bottom frictional dissipation is assumed. Both steady and time-periodic wind stresses invoke the upwind flow along the central trough of the Yellow Sea, independently of the presence of the oceanic current. The presence of oceanic currents very marginally alters the north-south gradient of the sea surface elevation in the Yellow Sea. Changes in the intensity and direction of the wind-induced mean upwind flow are hardly noticeable in the Yellow Sea but are found to be significant near Cheju Island where the gradient is reduced and therewith contribution of Ekman transport increases. In case of steady wind forcing circulation patterns such as two gyres on the slope sides, a cyclonic gyre on the western slope and an anticyclonic gyre on the eastern slope persist and the upwind flow composes part of the cyclonic gyre in the Yellow Sea. While in case of the time-periodic wind stress the appearance and disappearance of the patterns are repeated according to the time variation of the wind stress and the upwind flow accordingly varies with phase delay, mostly intensifying near the time when the wind forcing is approximately near the middle of the decaying stage.

The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.
