2005년 7월 21일, 중국인민은행은 위안화 환율 제도를 미 달러화에 대한 고정환율제에서 통화바스켓 기준 관리변동환율제로 변경하였다. 이러한 변화는 중국 기업들이 환율변동에 자유로울 수 없음을 의미한다. 본 연구는 변동환율제도 하에서 위안화 환율변동과 벤처기업의 재무적 성과 간의 관계에 대한 분석에 연구의 목적을 두었다. 본 연구의 분석과정 및 결과는 아래와 같다. 첫째, 벤처기업의 재무성과를 측정하기 위하여 중국 상하이 증권거래소에 상장된 기업 중 무작위로 산동성 벤처기업을 표본으로 선택하여 안전성, 수익성, 성장성, 활동성의 4가지 요소에 따라 분기별 재무지표를 추출하였다. 둘째, 환율변동 자료는 중국이 변동환율제도를 최초로 도입한 2005년 7월 21일부터 2008년 12월 31일까지의 일별 위안화 환율자료를 중국인민은행에서 수집하여 분기별 변동환율로 정리하였다. 셋째, 위안화 환율변동과 벤처기업의 재무성과 간 관계를 확인하기 위하여 본 연구는 피어슨 상관관계분석을 실시하였다. 그 결과로서 전반적으로 평가절상 된 위안화 환율변동은 기업의 부채비율, 총자산 회전율, 자기자본 회전율에 통계적으로 유의하게 약한 부(-)의 상관관계를 보이고 있었다. 그러나 기타 재무지표들과는 통계적으로 직접적인 상관관계가 파악되지는 않았다. 따라서 본 연구를 통해 위안화 가치의 상승이 단기적으로 중국 벤처기업들의 경상이익에 큰 영향을 미치지 않는다는 점과 중국 벤처기업의 외화자산 비중이 상대적으로 높다는 점을 확인할 수 있었다. 또한 이를 토대로 본 연구는 환위험 노출에 대한 대응책으로 위안화/외화 비율의 조정 등 효과적인 환위험 관리방법을 제시하였다. On July 21st in 2005, People's Bank of China (PBOC) turned the currency peg against the U.S. dollar into managed currency system based on a basket of unnamed currencies under China's exchanged rate regime. This change means that China's enterprises are not free from currency fluctuations. The purpose of this study is to analyze the relations between Renminbi fluctuations in the floating exchange rate and financial results of venture companies. The process and outcomes of this study are as follows, First, in order to measure the financial results of venture companies, I choose venture companies in Shandong Province listed on the Shanghai Stock Exchange (SSE) at random and several quarter financial sheets according to safety ratios, profitability ratios, growth ratios, activity ratios. Second, I arrange the daily Renminbi exchange rate data announced from July 21st, 2005 to December 31st, 2008 by PBOC into the quarterly data. Third, in order to confirm the relations between Renminbi fluctuations and financial results of venture companies, I carry out Pearson's correlation analysis. As a result, the revaluation of the Chinese Renminbi has weakly negative effects on debt ratio, total assets turnover ratio and equity turnover ratio in statistics. But the revaluation of the Chinese Renminbi is not related to other financial index in statistics. The result of this study is that the revaluation of the Chinese Renminbi has little influence on the export and import of Chinese venture companies and certifies the fact that Chinese venture companies have much foreign currency assets. In addition to avoid the currency exposure risk, this study shows the effective method about currency exposure risk which adjusts proportion of Renminbi to foreign currency.

Semaphoring is a transmembrane receptor which participates in many cytokine-mediated signal pathways that are closely related to the angiogenesis, occurrence and development of carcinoma. The present study was designed to access the effect of mono-antibody (mAb) guided radioimmunotherapy (RIT) on skin carcinoma and investigate the potential mechanisms. Semaphoring mAb was acquired from mice (Balb/c), purified with rProtein A column; purity, concentration and activity were tested with SDS-PAGE and indirect ELISA; specificity and expression on the cutanuem carcinoma line and tissue were tested by Western blotting; morphology change was assessed by microscopy. MTT assay and colony inhibition tests were carried out to test the influence on the proliferation of tumor cells; Western blotting was also carried out for expression of apoptosis-associated (caspase-3, Bax, Bcl-2) and proliferation-related (PI3K, p-Akt, Akt, p-ERK1/2, ERK1/2) proteins and analyse the change in signal pathways (PI3K/Akt and MEK/ERK). The purity of purified semaphorin mAb was 96.5% and the titer is about $1{\times}10^6$. Western blotting showed semaphoring mAb to have specifically binding stripes with semaphoring b1b2 protein, B16F10, and A431 cells at 39KDa, 100KDa and 130KDa, respectively. Positive expression was detected both in cutanuem carcinoma line and tissue and it mostly located in cell membranes. MMT assay revealed dose-relate and time-relate inhibitory effect of semaphorin mAb on A431 and B16F10. Colony inhibition tests also showed dose-relate inhibitory effects. Western blotting demonstrated the expression of apoptosis and proliferation-related protein and changes in signal pathway. In conclusion, we demonstrated that semaphorin is highly expressed on the tumor cell-surfaces and RIT with semaphorin mAb has effect in i nhibiting proliferation and accelerating apoptosis of tumor cells.

Purpose: As there are more cases of forged brands, change of awareness is urgently required at the gov-ernmental, corporate and consumer levels. Therefore. this study aims to positively analyze the correlation between forged brand quality and purchase irueruions perceived by consumers based on types of preference of luxury brands. Methods: In order to achieve the above purpose. this study derived a model of causal relationships among the forged brand quality, preference of typified Iuxury brands, and purchase intentions. SPSS 20.0 was applied for data processing. Frequency analysis ad descriptive statistical analysis were conducted for basic data and measurement tools were verified through feasibility and reliability analyses. Multiple regression analysis was conducted to verify the hypotheses. Results: Based on the results. only utilitarian quality positively (+) affected non-intrinsic preference while its impact on intrinsic preference was negative (-). On the other hand. hedonic quality was significantly positive (+) but the impact was not significant. Both utilitarian and hedonic qualities had significantly positive (+) impacts on the intentions to purchase forged brands with the impact of hedonic quality relatively higher. Conclusion: These results clarified that the overall consumption of Korean consumers had not entered its maturity, yet. Also. Korean consumers regard forged brands as alternatives to luxury brands mostly because of hedonic quality. As hedonic quality is added. Korean consumers` purchase intentions became higher. Based on these results, this study suggested the measures to be taken for the country to develop into an advanced country in the luxury market which is becoming more global and overcome the barrier of its old trend in imitation at the four levels of manufacturers. distributors. government, and consumers.

Xiao-Ling Zhong,Yi Dong,Wei Xu,Yu-Yuan Huang,Hui-Fu Wang,Tian-Song Zhang,Li Sun,Lan Tan,Qiang Dong,Jin-Tai Yu 대한뇌졸중학회 2021 Journal of stroke Vol.23 No.1

Background and Purpose: The present study aimed to compare the efficacy and tolerability of different blood pressure (BP)-lowering strategies. Methods: Randomized controlled trials that compared various antihypertensive treatments and stroke outcomes were included. Eligible trials were categorized into three scenarios: single or combination antihypertensive agents against placebos; single or combination agents against other agents; and different BP-lowering targets. The primary efficacy outcome was the risk reduction pertaining to strokes. The tolerability outcome was the withdrawal of drugs, owing to drug-related side effects (PROSPERO registration number CRD42018118454 [20/12/2018]). Results: The present study included 93 trials (average follow-up duration, 3.3 years). In the pairwise analysis, angiotensin-converting enzyme inhibitors (ACEis) and beta-blockers (BBs) were inferior to calcium channel blockers (CCBs) (odds ratio [OR], 1.123; 95% confidence interval [CI], 1.008 to 1.252) (OR, 1.261; 95% CI, 1.116 to 1.425) for stroke prevention, BB was inferior to angiotensin II receptor blockers (ARB) (OR, 1.361; 95% CI, 1.142 to 1.622), and diuretics were superior to ACEi (OR, 0.871; 95% CI, 0.771 to 0.984). The combination of ACEi+CCB was superior to ACEi+diuretic (OR, 0.892; 95% CI, 0.823 to 0.966). The network meta-analysis confirmed that diuretics were superior to BB (OR, 1.34; 95% CI, 1.11 to 1.58), ACEi+diuretic (OR, 1.47; 95% CI, 1.02 to 2.08), BB+CCB (OR, 2.05; 95% CI, 1.05 to 3.79), and renin inhibitors (OR, 1.87; 95% CI, 1.25 to 2.75) for stroke prevention. Regarding the tolerability profile, the pairwise analysis revealed that ACEi was inferior to CCB and less tolerable, compared to the other treatments. Conclusions: Monotherapy using diuretics, CCB, or ARB, and their combinations could be employed as first-line treatments for stroke prevention in terms of efficacy and tolerability.

Li-Xin Zhang,Yuan-Zhong Wang,Hong-Fang Jiu,Ya-Lei Wang,Yi-Xin Sun,Zhenzhong Li 대한금속·재료학회 2014 ELECTRONIC MATERIALS LETTERS Vol.10 No.2

Spinel Co-LiMn2O4 nanotubes have been synthesized via solid state reaction using α-MnO2 nanotubes as selftemplates. The as-prepared powders were investigated by XRD, TEM, and galvanostatic discharge/charge analysis. The optimal doping amount was confirmed by galvanostatic charge/discharge measurements. The results indicate that about 67% of initial capacity (115 mAh/g) of LiMn2O4 nanotubes can be retained after 50 cycles. For Co-LiMn2O4 nanotubes, the initial reversible capacity is 126.6 mAh/g and 100 mAh/g can be maintained after 50 cycles. The capacitance retention rate of Co-LiMn2O4 nanotubes is as high as 79%. These results indicate that the doping Co can effectively improve circle stability and electrochemical performance of LiMn2O4 nanotubes.
