본문은 저자 자신의 연구관점과 관련연구 결과들을 분석하여 연구된 것으로 즉, 미중 관계의 역사적 변화를 바탕으로 현대 미중 관계를 관찰하여 충돌과 화해를 중심으로 미중관계의 역사적 원인과 변화 가능성을 연구한 것이다. 즉, 이 논문은 현재 중국과 미국이 제로섬 게임을 향해 나아가고 있는지, 아니면 양측의 협상을 통해 점진적으로 변화하고 있는지를 분석하면서, 이 과정이 한반도 상황에 어떤 영향을 미칠 것인지에 초점을 맞춘 것이다. 지금까지의 연구 경험을 통해 보면, 동북아 관계는 미국과 중국 그리고 다른 강대국 관계뿐만 아니라 탈냉전 시대의 한반도를 둘러싼 국제 관계의 전형으로 나타난다고 할 수 있다. 따라서 한반도 문제는 동북아 주변국 간 국제 관계의 핵심이라고 할 수 있다. 동아시아에 살고 있는 우리에게 동북아와 동아시아를 포함한 글로벌 무대에서 미중관계는 매우 중요하며, 미국과 중국의 갈등과 화합은 이 지역을 포함한 세계의 평화와 안정에 매우 중요한 동인이 되고 있다. This article will start from the author’s own perspective, and does not represent the position of any organization or organization, that is, based on the historical evolution of Sino-US relations, observe modern Sino-US relations, and study the reasons and possibilities of modern Sino-US relations of opposition or reconciliation. In other words, this article will focus on studying whether China and the United States are moving toward a zero-sum game or whether they are gradually changing through the reconciliation relationship between the two sides, and what impact this process will have on the situation on the Korean Peninsula. I have studied the international relations between the Korean Peninsula and Northeast Asia for more than 30 years. From my research experience, Northeast Asian relations are the epitome of the relations between China and the United States and other major powers, as well as the international relations around the Korean Peninsula in the post-Cold War era. Therefore, the Korean Peninsula issue can be said to be a core part of the international relations between neighboring powers in Northeast Asia. For us living in East Asia, global Sino-US relations including Northeast Asia and East Asia are very important, and both conflict and harmony between China and the United States are critical to peace and stability in this field and the world.

( Ya-min Lai ),( Wei-yan Yao ),( Yao He ),( Xuan Jiang ),( Yu-bei Gu ),( Min-hu Chen ),( Yu-lan Liu ),( Yao-zong Yuan ),( Jia-ming Qian ) 대한소화기학회 2017 Gut and Liver Vol.11 No.2

Background/Aims: Patients with active ulcerative colitis (UC) have elevated levels of activated myeloid-derived leukocytes as a source of inflammatory cytokines. The selective deple-tion of these leukocytes by adsorptive granulocyte/monocyte apheresis (GMA) with an Adacolumn should alleviate inflammation, promote remission and enhance drug efficacy. However, studies have reported contrasting efficacy out-comes based on patients` baseline demographic variables. This study was undertaken to understand the demographic features of GMA responders and nonresponders. Methods: This was a multicenter study in China involving four institutions and 34 patients with active UC. Baseline conventional medications were continued without changing the dosage. The treatment efficacy was evaluated based on the endo-scopic activity index and the Mayo score. Results: Thirty of the 34 patients completed all 10 GMA treatment sessions. The overall efficacy rate was 70.59%. The receiver operating characteristic analysis showed that the area under the curve was approximately 0.766 for a Mayo score of ≤5.5 with 0.273 specificity and 0.857 sensitivity (Youden index, 0.584) for GMA responders. No GMA-related serious adverse events were observed. Conclusions: The overall efficacy of GMA in patients with active UC who were taking first-line medications or were corticosteroid refractory was encouraging. Addition-ally, GMA was well tolerated and had a good safety profile. (Gut Liver 2017;11:216-225)

Baihua Village is a typical mountainous village in the southwest part of Lujiang county, Longyang District, Baoshan City, Yunnan Province. Residents there made a living on the land, including growing sugarcane and planting maize, whose annual income was no more than 2000 yuan before 2006. Since then when a research institute has set it as one of the pilot villages for mango growing impetus with sci-tech. For the sake of “One village and One Product”, mango breeding and relevant techniques have been applied to daily work. Within years, the developed model of has been explored: simply “villages are the main carriers facilitated by the specialized cooperative for mango growing, back-up by science and technology. Technical trainings serve as the driving force for the leading growers, meanwhile, sellers work as the bridge link the producing-end and the markets”.

An optimized microwave-assisted extraction method for increasing yields of rare ginsenosides from Panax quinquefolius L.

Yao, Hua,Li, Xuwen,Liu, Ying,Wu, Qian,Jin, Yongri The Korean Society of Ginseng 2016 Journal of Ginseng Research Vol.40 No.4

Background: Rare ginsenosides in Panax quinquefolius L. have strong bioactivities. The fact that it is hard to obtain large amounts of rare ginsenosides seriously restricts further research on these compounds. An easy, fast, and efficient method to obtain different kinds of rare ginsenosides simultaneously and to quantify each one precisely is urgently needed. Methods: Microwave-assisted extraction (MAE) was used to extract nine kinds of rare ginsenosides from P. quinquefolius L. In this article, rare ginsenosides [20(S)-Rh1, 20(R)-Rh1, Rg6, F4, Rk3, 20(S)-Rg3, 20(R)-Rg3, Rk1, and Rg5] were identified by high performance liquid chromatography (HPLC)-electrospray ionization-mass spectrometry. The quantity information of rare ginsenosides was analyzed by HPLC-UV at 203 nm. Results: The optimal conditions for MAE were using water as solvent with the material ratio of 1:40 (w/v) at a temperature of $145^{\circ}C$, and extracting for 15 min under microwave power of 1,600 W. Seven kinds of rare ginsenosides [20(S)-Rh1, 20(R)-Rh1, Rg6, F4, Rk3, Rk1, and Rg5] had high extraction yields, but those of 20(S)-Rg3 and 20(R)-Rg3 were lower. Compared with the conventional method, the extraction yields of the nine rare ginsenosides were significantly increased. Conclusion: The results indicate that rare ginsenosides can be extracted effectively by MAE from P. quinquefolius L. in a short time. Microwave radiation plays an important role in MAE. The probable generation process of rare ginsenosides is also discussed in the article. It will be meaningful for further investigation or application of rare ginsenosides.

Qian, Yi-hua,Xiao, Hong-zhao,Nie, Ming-hao,Zhao, Yao-hong,Luo, Yun-bai,Gong, Shu-ling The Korean Institute of Electrical Engineers 2018 Journal of Electrical Engineering & Technology Vol.13 No.2

Based on the actual operating environment of transformer, the aging tests of nitrile butadiene rubber (NBR) were conducted systematically under four conditions: in air, in transform oil, under compression in air and under compression in transform oil to studythe effect of high temperature, transform oil and compression stress simultaneously on the thermal aging behaviors of nitrile butadiene rubber and predict the lifetime. The effects of liquid media and compression stress simultaneously on the thermal aging behaviors of nitrile butadiene rubber were studied by using characterization methods such as IR spectrosc-opy, thermogravimetric measurements, Differential Scanning Calorimetry (DSC) measurements and mechanical property measurements. The changes in physical properties during the aging process were analyzed and compared. Different aging conditions yielded materials with different properties. Aging at $70^{\circ}C$ under compression stress in oil, the change in elongation at break was lower than that aging in oil, but larger than that aging under compression in air. The compression set or elongation at break as evaluation indexes, 50% as critical value, the lifetime of NBR at $25^{\circ}C$ was predicted and compared. When aging under compression in oil, the prediction lifetime was lower than in air and under compression in air, and in oil. It was clear that when predicting the service lifetime of NBR in oil sealing application, compression and media liquid should be involved simultaneously. Under compression in oil, compression set as the evaluation index, the prediction lifetime of NBR was shorter than that of elongation at break as the evaluation index. For the life prediction of NBR, we should take into account of the performance trends of NBR under actual operating conditions to select the appropriate evaluation index.

Prediction method for steady-state response of local rubbing blade-rotor systems

Qian Zhao,Hongliang Yao,Qi Xu,Bang-chun Wen 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.4

Blade-rotor systems frequently encounter the problem of blade-to-case rubbing, which affects their safety and stability. Numericalsimulation can be used to predict the steady-state response of these systems. However, such simulation is frequently computationallyexpensive because of the high dimensions of the dynamic model of a blade-rotor system. To overcome this problem, a new method thatcombines the receptance-based dimension-reduction approach with the incremental harmonic balance (IHB) method is presented in thisstudy. First, a dynamic model of a blade-rotor system is developed using the finite element method, and the number of dimensions of themodel is reduced by the receptance method. Subsequently, the steady-state response is obtained by the improved IHB method to convenientlymanage the large number of super-harmonic components of the local rubbing system. Finally, the precision and efficiency of theproposed method is verified by comparing its results with those obtained by the Newmark-b method. The proposed method is found to beefficient in analyzing local rubbing blade-rotor systems with high dimensions, local nonlinearities, and rich super-harmonics.

Diagnosing Balamuthia mandrillaris amebic meningoencephalitis in a 64-year-old woman from the Southwest of China

Yao Suhua,Chen Xiaoting,Qian Lian,Sun Shizheng,Zhao Chunjing,Bai Zongkai,Chen Zhaofang,Wu Youcong 대한기생충학ㆍ열대의학회 2023 The Korean Journal of Parasitology Vol.61 No.2

Balamuthia mandrillaris amebic encephalitis (BAE) can cause a fatal condition if diagnosis is delayed or effective treatment is lacking. Patients with BAE have been previously reported in 12 provinces of China, with skin lesions being the primary symptom and encephalitis developing after several years. However, a significantly lower number of cases has been reported in Southwest China. Here we report an aggressive BAE case of a 64-year-old woman farmer with a history of skin lesions on her left hand. She was admitted to our hospital due to symptoms of dizziness, headache, cough, vomiting, and gait instability. She was initially diagnosed with syphilitic meningoencephalitis and received a variety of empirical treatment that failed to improve her symptoms. Finally, she was diagnosed with BAE combined with amebic pneumonia using next-generation sequencing (NGS), qRT-PCR, sequence analysis, and imaging studies. She died approximately 3 weeks after the onset. This case highlights that the rapid development of encephalitis can be a prominent clinical manifestation of Balamuthia mandrillaris infection.

<P>To investigate anatomical differences across individual subjects, or longitudinal changes in early brain development, it is important to perform accurate image registration. However, due to fast brain development and dynamic tissue appearance changes, it is very difficult to align infant brain images acquired from birth to 1-yr-old.</P>
