중국은 매우 빠른 속도로 발전하고 있다. 새롭고 복잡한 환경의 출현은 대량의 안내 표지를 절실히 필요로 한다. 그러나 중국의 안내 표지 디자인의 관련 연구는 아직 시작 단계에 처해있고, 이에 대응하는 이론 연구도 상대적으로 뒤처져 있다. 중국 도시 상황으로 살펴보면, 효과적인 이론 지도가 없다는 전제하에, 많은 사인 그래픽 기호의 사용은 모두 체계적이지 않고, 사인디자인의 각도에서는 그래픽 기호를 합리적으로 조직하고 사용하지 않는다. 게다가 승객이 역명을 잘못 파악하는 등 많은 문제들이 자주 발생하기 때문에, 본 연구에서는 그래픽 기호학 이론 연구 방법을 통해서, 해외 저명 사례를 조사 분석하고, 중국 무한(武汉) 지하철 4호선에 그래픽 기호학을 적용하여, 이후 실험 모형을 통하여 그래픽 기호를 무한 지하철의 사인 시스템에 응용하면, 빠르고 효과적으로 역명을 식별할 수 있고, 무한 지역의 창의적인 도시 특색을 확연히 드러낼 수 있음을 발견할 수 있었다. China is in the process of high maturity. New and complex environment is in urgent need of sign system, while the related research of China’s sign design is still in its infancy and the corresponding theoretical research is relatively lagging. In general, foreign sign design has more images, less literal data, and is lack of interpretation and analysis of the idea and design method, from practice. The experience taken from practice is very limited. Currently, many Chinese cities do not have a theory of effective sign system on many occasions lead to the use of the sign system are more casual. It even exists many description unexplained problems and so on. Therefore, this paper through the theoretical study of semiotics and graphical, and analysis the typical cases overseas, and thus proposed a proposal which use sign system in Wuhan Metro Line. Through the model test of use graphical symbols in Wuhan Metro sign system, it is not only can fast and effectively identify the name of the station, but also to highlight the city of Wuhan personalized features.

( Yu Mei Liu ),( Ming Jun Chen ),( Meng Hui Wang1 ),( Rui Bao Jia ),( Li Li ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.9

Growth of Microcystis aeruginosa could be inhibited significantly within 24 h by the extracellular substances prepared from Aeromonas sp. strain FM. During the treatment, the concentration of extracellular soluble carbohydrates increased significantly in algal culture. Morphological and ultrastructural changes in M. aeruginosa cells, including breakage of the cell surface, secretion of mucilage, and intracellular disorganization of thylakoids, were observed. HPLC-MS analysis showed that the extracellular substances of Aeromonas sp. strain FM were a mixture of free amino acids, tripeptides, and clavulanate. Among these, the algaelysis effects of lysine and clavulanate were confirmed.

Changes and Features of Indian Diplomacy in the Context of the US Indo-Pacific Strategy

Wang Rui(Rui Wang),Wang Linwei(Linwei Wang) 아시아사회과학학회 2023 Jornal of Asia Social Science Vol.10 No.2

During the Trump administration (January 2017 to December 2020), the United States formulated the “Indo-Pacific Strategy” and officially established a strategic competition with China throughout the government. The strategy aimed to woo allies and partners in the Indo-Pacific region and accelerate the construction and promotion of the “Quadrilateral Security Dialogue”. India, as the “world's largest democracy”, has unresolved border issues with China, making it a key target for the United States to woo, and thus forcing India to change its foreign policy. On February 11, 2022, the Biden administration introduced a new version of the “Indo-Pacific Strategy”, which further clarified the overall framework of strategic competition with China, continued to deepen the strategic setting with the prominent features of wooing allies and confronting China, emphasized the core role of the Quad and the central position of ASEAN countries, highlighted the military deterrence of the US-UKAustralia alliance, and created an “anti-China circle” in multiple fields such as biosecurity, science and technology, economic finance, and climate change. Although India is the founding country of the Non-Aligned Movement and has long relied on “independent and autonomous” foreign policy, the current new geopolitical environment where Sino-Indian relations are at a low point due to the border issue, Russia-Ukraine conflicts continue due to NATO's eastward expansion, and the rapid development of the Quad, signifies the power balance in the Asia-Pacific and Indian Ocean regions. This also indirectly reflects the progress of India's own “Indo-Pacific Strategy” and the implementation of the US “Indo-Pacific Strategy”, thus providing a dimension for predicting the development trend of the strategic competition between China and the US.

The snakehead fish, Channa siamensis, belongs to the genus of Channa (perciformes: Channidae) and was first reported by Günther in 1861. Despite it has been described approximately for 15 decades, the genetic information is limited and the taxon status of this kind of fish is still unclear. The primary objective of this study is to get more genomic data and calculate the taxon location of this kind of fish. The next generation sequencing method was used to obtain the whole mitochondrial DNA information, and bioinformatic analysis was performed to investigate the evolutionary status and taxon location of C. siamensis. The circular mitochondrial DNA was 16,570 bp in length, and which showed typical piscine structure and arrangement. The overall nucleotide composition was 29.28% A, 24.72% T, 30.71% C, 15.29% G, with 54.1% AT, respectively. Phylogenetic analyses using concatenated amino acid and nucleotide sequences of the 13 protein-coding genes with two different methods (Maximum likelihood and Bayesian analysis) both highly supported C. siamensis belongs to the genus Channa and shows a close relationship with C. micropeltes. These data will provide more useful information for a better understanding of the mitochondrial genomic diversities and evolution in fish as well as novel genetic markers for studying population genetics and species identification.

Wang, Chao,Xiao, Qian,Li, Yu-Wen,Zhao, Chao,Jia, Na,Li, Rui-Li,Cao, Shan-Shan,Cui, Jia,Wang, Lu,Wu, Yin,Wen, Ai-Dong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Adenocarcinoma of lung has high incidence and a poor prognosis, woith chemotherapy as the main therapeutic tool, most commonly with cisplatin. However, chemotherapy resistance develops in the majority of patients during clinic treatment. Mechanisms of resistance are complex and still unclear. Although annexin play important roles in various tumor resistance mechanisms, their actions in cisplatin-resistant lung adenocarcinoma remain unclear. Preliminary studies by our group found that in cisplatin-resistant lung cancer A549 cells and lung adenocarcinoma tissues, both mRNA and protein expression of annexins A1, A2 and A3 is increased. Using a library of annexin A1, A2 and A3 targeting combined molecules already established by ourselves we found that specific targeting decreased cisplatin-resistance. Taken together, the underlined effects of annexins A1, A2 and A3 on drug resistance and suggest molecular mechanisms in cisplatin-resistant A549 cells both in vivo and in vitro. Furthermore, the study points to improved research on occurrence and development of lung adenocarcinoma, with provision of effective targets and programmes for lung adenocarcinoma therapy in the clinic.

With the continuous expansion of the scale of distributed power generation,multi grid connected converters often prone to oscillation problems when parallel operation.In this paper,we study the equivalent circuit of parallel connection of multi grid connected converters , system response characteristics of voltage source and in-depth analysis of the causes of the parallel oscillation of the converters.This paper analyzes converter’s parallel complex vector model by complex vector and comes to a conclusion that power grid voltage feed-forward will produce strong coupling between converter so that cause oscillation parallel converters. In view of the above problems and the flow of the converter starting or the voltage fluctuation of the grid, we design a low feed forward method, that is to make the fundamental and the main sub components of the grid voltage forward without delay and for the relative high frequency components, the filter technology is used to attenuate, so as to achieve the maximum elimination of the feed-forward coupling between the converter, to prevent the occurrence of system oscillation. In order to verify the use of this paper, the theory of the parallel converter is applied in the field of MW level wind field. The experimental results prove the correctness of the theory.

Rui Zhou,Kun Zhou,Lina Wang,Binrui Wang 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.3

Aiming at the problems of poor adaptability of traditional dynamic window algorithms and difficult toquickly and effectively plan paths in the face of complex obstacles such as spiral obstacles and narrow obstacles,we propose an improved dynamic windows approach path planning algorithm based on A* algorithm and artificialpotential field method fusion. Firstly, we improve the security constraints of the dynamic window algorithm, replace the obstacle distance evaluation function in the original algorithm with the artificial repulsion field function,and add the target endpoint distance sub-evaluation function. Secondly, the improved dynamic window method isintegrated with the A* path smoothed by gradient descent method, which solves the problem of poor global planning of the traditional algorithm. And the weight of the evaluation function will adaptively change according tothe surrounding environment, which enhanced the adaptability of the algorithm. Finally, through the comparison ofsimulation results, we verified that the fusion algorithm has a great improvement in planning efficiency, safety, andpath smoothness, and is more in line with the motion characteristics of mobile robots.

Wang, Rui-Tao,Xu, Xin-Sen,Liu, Jun,Liu, Chang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.6

Objective: To evaluate the prognostic factors of gallbladder carcinoma. Methods: Presentation, operative data, complications, and survival outcome were examined for 132 gallbladder carcinoma patients who underwent gallbladder surgery in our unit during 2002-2007, and follow-up results were obtained from every patient for univariate and multivariate survival analysis. Results: The univariate analysis showed that gallbladder lesion history, tumor cell differentiation, Nevin staging, preoperative lymph node metastasis and the surgical approach significantly correlated with the prognosis of the patients (p<0.05). The results of the multivariate analysis (Cox regression) showed that gallbladder lesion history, Nevin staging and the surgical approach were independent predicators with relative risks of 6.9, 4.4, 2.8, respectively (p=0.002, 0.003, 0.008). Conclusion: Gallbladder lesion history, Nevin staging and the surgical approach are independent prognostic factors for gallbladder carcinoma, a rapidly fatal disease. Therefore, early diagnosis, anti-infective therapy and radical surgery are greatly needed to improve the prognosis of gallbladder carcinoma.

Metabolism of α-Actin, Expression of α-Actin mRNA and MHC mRNA Induced by Exhaustive Eccentric Exercise in Skeletal Muscles of Rats and Effects of Acupuncture on Them

Wang, Rui Yuan,Yuan, Yu He,Zhang, Wen Dong,Zhao, Lin,Xun, Chuu Yan 한국체육무용국제교류학회 2001 한국체육무용국제교류학회지 Vol.7 No.-

The purpose of this study is to investigate the changes of α-actin metabolism, α-actin mRNA and MHC mRNA expression in skeletal muscles of rats after one set exhaustive eccentric exercise and the effects of acupuncture on them. 130 adult male SD rats were randomly divided into the sedentary group and the exercise group. The rats of the exercise group were again divided into the acupuncture group and non-acupuncture group. According to the sampling time, the exercise group (the acupuncture and non-acupuncture group) was divided into 12 groups, that is the 0 hours, 6 hours, 12 hours, 24 hours, 48 hours and 72 hours groups. In each group there were ten rats. The rats weighting 205±23.3 (mean±SE) were maintained at 23±1℃. They were fed in different chests taking food and drink freely. The rats of the exercise group carried out continuous downhill running with the speed of 16m/min for about 4 hours until exhaustion on the animal treadmill (degree -16°). The rats of the acupuncture group were treated with acupuncture immediately after exhaustive eccentric exercise, but those of the sedentary group and the non-acupuncture group were treated without acupuncture. They were the control groups. The muscle samples were taken immediately, 6 hours, 12 hours, 24 hours, 48 hours and 72 hours after exercise. The contents of G-actin, F-actin and T-actin in skeletal muscles of rats were measured by means of Dnase I assay. The gene expression of α-actin m RNA and MHC isoforms mRNA were determined by using the quantitative reverse transcription PCR technology. Compared with the sedentary group, there was no remarkable change of T-actin after exercise. The decrease G-actin could be detected only immediately after exercise. The content of F-actin was significantly higher than that of the sedentary group 0~6 hours after exercise, but 12~24 hours after exercise it decreased to a lower level than that of the sedentary group. A delayed increase of F-actin depolymerization presented after exercise. The F-actin value of the acupuncture group was improved in a lower range than that of the non-acupuncture group 0~6 hours after exercise, but 12~24 hours after exercise it was remarkably higher than those of the non-acupuncture group. It was shown that acupuncture could regulate the F-actin concentration in skeletal muscles of rats after exercise. Furthermore, the regulation might be bilateral. Acupuncture could stop the increase of F-actin delayed depolymerization induced by high loading exercise. The gene expression of α-actin mRNA in skeletal muscles of rats decreased significantly after one set exhaustive exercise. The duration of its recovery was longer than 72 hours. It might be that acupuncture accelerated the recovery process of α-actin mRNA expression after exercise. The MHC mRNA expression of the non-acupuncture group was lower than that of the sedentary group 6~12 hours after exercise. There appeared a delayed excess expression of MHC mRNA 48 hours after exercise. The curve of the change of the total MHC mRNA expression in the acupuncture groups was similar to that in the non-acupuncture group. The duration of recovery of the acupuncture group was shorter, the delayed excess expression of MHC mRNA was ahead of time and its range was higher than that of non-acupuncture group. It was shown that acupuncture could promote the recovery of MHC mRNA expression after exercise of high load
