Yuan Zhimin(袁智敏) 세계문화관광학회 2010 Conference Proceedings Vol.11 No.0

跨文化交际应是世界旅游交往中的一座“理解的桥梁”, 帮助我们去认识和了解异域文化, 更好地促进国际间旅游交流和发展。然而鉴于不同文化之间的差异以及对异域文化缺乏了解, 旅游者与旅游目的地居民双方在交往中,容易出现不恰当言行,产生交际摩擦,影响跨国旅游的顺利进行。本文从语用的角度,分析了文化差异的类别以及对导游翻译的负面影响,进而提出了消除文化差异负面影响的应对策略。 Cross-cultural interaction is a bridge of understanding through which people can get familiar with and understand different cultures. But due to the differences between the cultures and misunderstanding, conflicts and clash often occur between the tourists and local people of the destination country and it greatly obstruct tour programs in smooth implement. From the viewpoint of pragmatics, the thesis categorizes the cultural difference, analyzes its negative impact on the translation of guiding words, and put forward some measures to overcome the conflicts.

跨国旅游与跨文化交际

袁智敏(Yuan Zhimin) 세계문화관광학회 2009 Conference Proceedings Vol.10 No.0

跨国旅游是一种社会文化活动,对于人类文化传播有着积极作用。然而不同的文化背景和风俗习惯,给旅游主、客地人们的交往造成许多冲突和误解,进而影响到旅游活动的顺利进行。本文以跨文化交际理论为依据,阐述了放游跨文化交际的属性及旅游与跨文化交际的关系,并根据具体案例,从价值观念,社会规范、人际交流行为等文化差异,分析跨国旅游中产生交际冲突的原因,同时提出了应对建议。 Transnational Tour is a kind of social activities playing an important role in transnational cultural transmission. However, the existing cultural differences cause misunderstandings and conflicts in the communications between people from tourist resource countries and from target countries so as to greatly obstruct tour programs in smooth implement Having a study on the relationship between transnational touring and intercultural communication, the thesis will make detailed analyses on the causes of cultural conflicts occurred through case study, and then put forward measures to solve the problems as well.

Regenerated coenzyme-based preparation of bienzyme-polymer nanoconjugates and their applications for the synthesis of ethyl (R)-2-hydroxy-4-phenylbutyrate

Yuan Lu,Hongqian Dai,Pengpeng Cheng,Hanbing Shi,Lan Tang,Xingyuan Sun,Zhimin Ou 한국화학공학회 2021 Korean Journal of Chemical Engineering Vol.38 No.5

A modular approach was applied for the synthesis of bienzyme-polymer nanoconjugates (nano-BECs) (50- 70 nm) consisting of two enzymes (carbonyl reductase and glucose dehydrogenase) conjugated within a single universal polymer scaffold. The amount of the product ethyl (R)-2-hydroxy-4-phenylbutyrate (R-HPBE) with nano-BECs as the catalyst was 533mM in a dibutyl phthalate-phosphate buffer (dibutyl phthalate-PB) biphasic system, while the amount of R-HPBE was 349mM using carbonyl reductase-poly(acrylic acid) as the catalyst, indicating that the nano- BECs have an advantage for coenzyme regeneration. Compared with a single aqueous phase, the substrate treatment capacity was improved at the interface of the dibutyl phthalate-PB biphasic system. Under the optimal reaction conditions (35 oC, 40 h, dibutyl phthalate-PB 1 : 1), nano-BECs can completely convert substrate into optically pure R-HPBE (enantiomeric excess (e.e.) >99.9%) in the organic-aqueous system.

A combined approach to evaluate activity and structure of soil microbial community in long-term heavy metals contaminated soils

Tianqi Wang,Zhimin Yuan,Jun Yao 대한환경공학회 2018 Environmental Engineering Research Vol.23 No.1

In the present study, long-term heavy metals (HMs) contaminated soil samples from a well-known Pb/Zn smelting area in the southwest of China were collected, and physicochemical and biological characteristics of these samples were evaluated. Soil samples contained different concentrations of HMs, namely Pb, Zn, Cu, and Cd. Enzyme activity analyses combined with microcalorimetric analysis were used for soil microbial activity evaluation. Results showed that two soil samples, containing almost the highest concentrations of HMs, also shared the greatest microbial activities. Based on correlation coefficient analysis, high microbial activity in heavily HMs contaminated soil might be due to the high contents of soil organic matter and available phosphorus in these samples. High-throughput sequencing technique was used for microbial community structure analysis. High abundance of genera Sphingomonas and Thiobacillus were also observed in these two heavily contaminated soils, suggesting that bacteria belonging to these two genera might be further isolated from these contaminated soils and applied for future studies of HMs remediation. Results of present study would contribute to the evaluation of microbial communities and isolation of microbial resources to remediate HMs pollution.

( Tong Liu ),( Jianghua Cheng ),( Zhimin Yuan ),( Honghu Hua ),( Kangcheng Zhao ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.9

Smoke detection is helpful for early fire detection. With its large coverage area and low cost, vision-based smoke detection technology is the main research direction of outdoor smoke detection. We propose a two-stage smoke detection method combined with block Deep Normalization and Convolutional Neural Network (DNCNN) and visual change image. In the first stage, each suspected smoke region is detected from each frame of the images by using block DNCNN. According to the physical characteristics of smoke diffusion, a concept of visual change image is put forward in this paper, which is constructed by the video motion change state of the suspected smoke regions, and can describe the physical diffusion characteristics of smoke in the time and space domains. In the second stage, the Support Vector Machine (SVM) classifier is used to classify the Histogram of Oriented Gradients (HOG) features of visual change images of the suspected smoke regions, in this way to reduce the false alarm caused by the smoke-like objects such as cloud and fog. Simulation experiments are carried out on two public datasets of smoke. Results show that the accuracy and recall rate of smoke detection are high, and the false alarm rate is much lower than that of other comparison methods.

Removal of Cr(VI) from aqueous solution by rice husk derived magnetic sorbents

Ruifeng Yang,Shangru Zhai,Yuan Fan,Zhimin Lei,Na Liu,Jialiang Lv,Bin Zhai,Lei Wang 한국화학공학회 2016 Korean Journal of Chemical Engineering Vol.33 No.4

−A novel magnetic porous sorbent obtained from agricultural waste rice husk was successfully synthesized through a simple carbon-thermal method. The sorbent was characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, vibrating sample magnetometer, N2 sorption analysis, and X-ray photoelectron spectroscopy. The removal efficiency of the sorbent for Cr(VI) was also investigated. Chromium adsorption was fitted by the pseudo-second-order and Langmuir models. The maximum chromium adsorption capacity, Brunauer-Emmett-Teller surface area, and average Barrett-Joyner-Halenda pore size of the magnetic sorbent were 157.7mg·g−1, 134.1m2·g−1, and 4.99 nm, respectively. The saturated magnetization of the novel adsorbent was 77.8 emu·g−1, indicating that the material can facilitate separation and recovery from aqueous systems. The removal mechanisms of Cr(VI) were also discussed. The result illustrates that rice husk-derived magnetic carbonaceous materials are a potential adsorbent for Cr(VI) pollution treatment and provide a suitable method for the effective conversion of biomass waste, which may solve the problem of waste disposal and widen the applications of the materials.

Performance analysis and experimental verification of hydraulic driven axial flow pumps

Zhiting Tong,Ye Yuan,Chao Zhang,Zhimin Zhang,Yue Zhang 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.6

To investigate axial flow pumps’ performance characteristics, NUMECA software is selected to perform numerical simulation at four rotating speeds (1380, 1840, 2300, and 2530 r/min) based on the Spalart-Allmaras turbulence model. The relationship curves of flowhead and flow-pump efficiency, static pressure distribution on blade surfaces, velocity variation near the hub, and total pressure distribution at different blade heights are obtained. Results indicate that with the improvement of the rotating speed, the curves of the head and the efficiency rise and shift to the right, the pressure difference on both sides of the blade ascends, and the moment acting on the blade induced by the water flow also increases, resulting in higher head. At the rated speed of 2300 r/min, the pressure difference between the pressure side and the suction side at low flowrates increases, the minimum pressure is lower, and the anticavitation performance decreases, whereas the velocity distribution near the hub is the same at different flowrates. Moreover, the velocity is lower near the hub’s leading edge, and no influence is observed. To guarantee the reliability and comparability, experimental data are contrasted with the simulated results at the speed of 2182 r/min. At the near design condition (Q = 534.4-567 m 3 /h), the relative deviation of efficiency and head is less than 4.5 %, which is a small gap. These conclusions provide valuable reference for axial flow pumps to operate under variable speed conditions.

The present pilot project was executed to recommend a strategy of clonorchiasis control in China. The pilot area of this project was Zhaoyuan, Hailin, and Ningan, Heiloagjiang province. A baseline survey subjecting 4,865 residents in Heilongjiang confirmed Zhaoyuan asa high endemic area and Hailin and Ningan as moderate endemic areas. Six different control strategies were implemented in Zhaoyuan, two were in Hailin, and one was in Ningan. Including the baseline survey and project programs from 2000 to 2004, total 63,274subject-times were examined of their feces for Clonorchiseggs, 26,680 were treated, 10,082 were screened by ELISA, and 6,130 subjects were examined of their liver by sonography. The egg Positive rates in 6 villages of Zhaoyuan were as high as 44.8% 70,0%. Following the protocolof each strategy, the subjected residents were examined of their feces and treated with 25 mg/kg praziquantel, 3 times. Except the control group, all of the villages showed 72.8% to 92.0% reduction of their original egg Positive rates at Zhaoyuan. Mass treatments of all subjected residents in 2001 and 2003 reduced the egg rate from 68.8% to18.7% and 4 annual mass treatments reduced the rate from 44.8% in 2001 to 8.7% in 2004.Selective annual treatments of egg positive subjects reduced the egg rates from 50.8% in2001 to 13.8% in 2004 or from 70.0% in 2001 to 11.6% in 2004, and two treatments in a year reduced the rate from 57.6% in 2001 to 4.6% in 2004. According to repeated treatments, EPG counts decreased remarkably. In moderate endemic areas, the original egg rates were 22.6% and 28.3% in 2001 but were 1.7% and 1.1% after 2 or 3 selective treatments. The present findings of the chemotherapeutic control of clonorchiasis prove that repeated medication is important. The reduction is directly correlated with dose of praziquantel but not with mass or selective treatments. Chemotherapeutic control of reservoirhosts has little effect on reinfection of clonorchiasis because the field along the Songhua-jiang is too wide to be impacted. ELISA confirmed many serologically positive cases to Clonorchisantigen but only a few cases were positive to other antigens (Paragonimus, cysticercus, sparganum). The abdominal soaography visualized intrahepatic bile duct dilatation and periductal echo in 2,002 of 6,070 examined subjects. In addition to these examinations and treatment, health education supplemented tㅗe control activities. The present findings prove clonorchiasis is very widely prevalent and heavily endemic along the rivers in Heiloagjiang. The results suggest that group chemotherapy with praziquantel is effective to reduce endemicity of clonorchiasis. Mass treatment without individual fecal examination is recommended in heavy endemic areas where the egg rate is over 40% while one selective treatment is effective enough in moderate endemic areas.
