With the popularization of higher education in China,the employment situation of college students is more complex and severe.This paper adopts the questionnaire method to explore the employment view of acupuncture and tuina undergraduates of Yunnan University of Traditional Chinese Medicine.The employment concept of acupuncture and tuina undergraduates in the minority border areas has changed greatly.After graduation,97.95%of students choose to work in fields related to medicine and acupuncture,prefer positions close to home,and are attracted to high-salary companies,among other factors.Therefore,enhancing the competitive advantages of medical students by guiding their career planning,providing employment selection advice,fostering innovation and entrepreneurship,improving basic skills,and offering graduate entrance examination guidance is crucial for broadening their employment opportunities. 展开更多

Guangxi is in the southwest border of China, and Guilin landscape and ethnic customs as the two "trump cards" have been widely utilized in the communication between Guaaagxi and the outside world. In fact, Guangxi owns many cultural resources such as humanity history, characteristic diet, and local operas to be further promoted, among which historical figures resources are especially abundant. However, the development and protection of the historical figures resources are inconsistent with the current economic and social development, and feature obviously certain hysteresis. In this paper, by taking Mrs. WA who was a heroine of the Zhuang nationality to resist foreign invasions in the Ming Dynasty, the necessary development road of the historical figures resources is explored based on analyzing the current development and protection of the historical figures resources in China' s Guangxi border areas, and then innovative concepts and new ideas are proposed with great efforts. 展开更多

Among the factors influencing tourist trail network development are political issues, including the presence of state borders, the possibility of crossing them and the accessibility of border zones. In the article, it was decided to look at changes in the offer of tourist trails(hiking and cycling) along the entire border of the Czech Republic after the extension of the Schengen area(within this area, crossing the border is possible anywhere, and not only at official border crossings). It should be emphasized here that the borders of the Czech Republic over most of their length run through mountainous areas and, apart from political factors, natural features should have a major impact on the development of tourist routes. In order to determine the coherence of the current network of trails on both sides of the Czech Republic state border, modern tourist maps have been analyzed, determining the number of places where it is possible to cross the state border with the help of a marked tourist trail. Based on that, two indicators were introduced to determine the degree of openness with all neighboring countries as regards the opportunity to cross on a tourist trail. Changes in the historical situation, a comparison of the accessibility of the border area before entering the Schengen area and 2019, were analyzed for two study areas using archival maps. Over a decade after the extension of the Schengen area, the number of places where tourist trails of neighboring countries approach the border has clearly increased. Crossing is more often made possible using hiking trails than cycling routes(trails of the first type cross the border every 7.91 km, while the latter every 13.3 km), but considering the speed of movement, it can be assessed that the openness for cyclists is higher than for hikers. Moreover, in many places there is still significant potential for further integration of tourist trail networks as trails created in one country often do not have a continuation on the other side of the border. 展开更多

Due to the difficult segmentation of land destiny, popularity destiny, industry destiny on the platform of common interests demand, the regional governance of production and living for the needs of the people in cross-regional areas, such as in the aspects of security, education, assignment and management of water resources, transportation, energy, environment protection and public health, the administrative border regional cooperation is relatively easy. These aspects are equivalent to public products. Just because of this, it leads to problems that nobody will not control. The governments, in order to realize regional economic coordinated development and to eliminate the regional interests parties of administrative regions economy in microcosmic, were adapting various self-protection measures, even including that "you may have your policy but I have my countermeasures" that is derived from inter-regional economic relations. The action of market segmentation has limited the flow of various economic development elements, especially the condition of "dead end highway", resource exploitation and use, difficult social security work in social living of the administrative boundary zone. This paper studies the typical economical district of Wuling mountain area in the obvious strategic position at the junction of Chongqing, Guizhou, Hunan, Hubei provinces from the angle of regional public management and public choice to present issue awareness and academic purpose. 展开更多

Objective: To investigate the microecology and common infection of the female vagina in border area of Chongzuo City. Methods: Female patients in the outpatient department and inpatient department of gynecology of our hospital from April 1, 2018 to August 23, 2021 were selected as the research objects. The reproductive tract secretions of all patients were examined by microecological examination, morphological examination, chemical analysis and microscopic examination, and the results of various indicators were statistically analyzed to draw relevant conclusions. Results: Among the 1498 women with vaginal micro- ecological imbalances, cleanliness was determined to be 534 cases of degree II, 868 cases of degree III, and 96 cases of degree IV;Nugent scores were 9 - 10 in 9 cases, 8 in 122 cases, 7 in 30 cases, 6 in 18 cases, 5 in 8 cases, 4 in 717 cases, 3 in 248 cases, 2 in 209 cases, 1 in 118 cases, and 0 in 19 cases. AV scores were 8 in 1 case, 7 in 1 case, 6 in 2 cases, 5 in 9 cases, 4 in 84 cases, 3 in 207 cases, 2 in 850 cases, 1 in 284 cases, and 0 in 60 cases. Among the pathogen infections, 99 cases were mycoplasma, 361 cases were candida, 199 cases were bacterial and 8 cases were trichomonas;In chemical analysis, there were 138 cases with pH 5.1, 326 cases with pH 4.8, 775 cases with pH 4.6, 217 cases with pH 4.4, and 42 cases with pH 4.1;meanwhile, 1390 cases were positive for hydrogen peroxide, 505 cases were positive for glucosidase, 487 cases were positive for acetylglucosaminidase, 184 cases were positive for sialidase, 290 cases were positive for proline amino-peptidase, 501 cases were positive for coagulase, and 1064 cases were positive for leukocyte esterase. Conclusion: Female reproductive tract microecology is more complex, and the pathogens of infection are also diverse. A systematic examination can clarify the occurrence and development of the disease, and then provide reliable laboratory data for clinical treatment and guide clinical medication. 展开更多

Exploring the spatial and temporal evolution characteristics of the border land use multifunctionality(LUMF)provides insights for taking advantage of border land use and optimizing border land use policies.Based on the improved Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS)mode,this study identifies and evaluates the LUMFs in the China-Vietnam border area between 2000 and 2018 from the perspectives of agricultural production,social security,ecological service,landscape recreation,and national security.The results show that:1)The comprehensive land use functions in most counties and cities continued to be improved.2)The comprehensive land use function exhibits remarkable spatial divergence and aggregation characteristics.The high-value area of the agricultural production function and social security function evolves from the east to the west.In addition,the spatial evolution of ecological service function is complicated,without an obvious spatial divergence and aggregation pattern.The landscape recreation function shows different spatial differentiation characteristics in the early and middle stage,and forms a large cluster in the later stage.Finally,the spatial evolution pattern of the national security function is significant.3)Designing differentiated border land policies,improving border land use security,and establishing a long-term mechanism for ecological protection and ecological compensation can aid in optimizing the LUMF level in the border area. 展开更多
