At present, under the background of "One Belt and One Road", great achievements have been made in cultural confidence, overseas communication, education, and modernization of Chinese medicine. However, the overseas dissemination of Chinese medicine culture has not yet fulfilled the requirements of the Cultural Power Strategy and the historical mission of Chinese medicine. Challenges are still faced in the cultural theory of traditional Chinese medicine, overseas communication mechanisms, and translation of Chinese medicine terms. Therefore, Chinese medicine practitioners must firm their faith in culture and traditional Chinese medicine, disseminate the cultural theory of traditional Chinese medicine, exert the advantages of the media and improve its mechanism, and speed up cross-cultural language exchange and research. These efforts will innovate Chinese medicine culture, strengthen overseas exchange and cooperation as well as flourish traditional Chinese medicine overseas.

A hydrochemical comparative study of groundwater in uraniferous sedimentary rock of the Ogcheon belt was carried out to investigate the genetic relationship between uraniferous groundwater of Daejeon area and uraniferous sedimentary rocks of the Ogcheon zone. The groundwater shows weak alkaline pH values rangingfrom 6.4 to 8.1 and low Eh values ranging from -50 to 225 mV. The groundwaters to Ca-$HCO_3$ type that shows high concentration of $Ca^{2+}$ and $HCO_3^_$ due to the dissolution of carbonate mineral in limestone. The concentration of uranium in the groundwater was measured very low below $3.2{\mu}g/L$, while it was detected as much as $1165{\mu}g/L$ in the mine waste water. The low Eh value of groundwater is one of the main causes of low uranium concentration of groundwater in uraniferous sedimentary rocks in the Ogcheon belt. It is suggested that the uranium of groundwater in granitic region of Daejeon area was not mainly provided from uraniferous sedimentary rocks in the Ogcheon belt.

In this paper, a primary pressure regulating type ratio control system is developed for a metal belt CVT, and the CVT ratio changing characteristics are investigated by simulation and experiment. The hydraulic part of the ratio control system has a simple structure with one 3-way spool valve as a main ratio control valve and one bleed type variable force solenoid as a pilot valve. The mathematical modelling of the CVT hydraulic system is derived by considering the CVT shift dynamics. Simulation results of CVT speed ratio and the primary pressure agree with the experimental results demonstrating the validity of the dynamic models. It is found from the simulation and experimental results that the response time of speed ratio and primary pressure can be shortened by increasing the ratio control valve port area, and the size of feedback orifice of ratio control valve gives a damping effect on the primary pressure oscillation.

For more than a decade components of low alloy iron powder with nickel and/or molybdenum for general engineering applications have been manufactured from powder metal. In the time to come such PM steel components will gain increasing significance. Because of various manufacturing difficulties they are mostly produced in two separate steps - sintering and hardening - which means high energy and labour requirements. The paper describes how such PM components are produced in just one run through a conveyor belt furnace with automatic atmosphere control and gas quenching zone. Energy and labour costs are low and reproducible quality is exceilent. The mechanical properties obtained with some powder alloys are presented as well.

In this study, product design and prototype manufacturing of a plastic water-pump pulley has been tried. The designed model is supposed to be made of 33 % glass reinforced resin of which the tensile strength is 180 MPa, and has 24 ribs on each side to increase its structural strength. Structural analysis under a static load of 300 kgf acting on both edges of the belt has been carried out using a commercial finite element code, MARC. The analysis result showed the maximum effective stress near a rib of designed model would be at most 35 MPa (less than 20% of the tensile strength), therefore, the plastic product would be sufficiently safe under that loading condition. On the basis of the structural analysis, a prototype of the designed model has been manufactured by using the fused deposition modelling (FDM) method which is one of the rapid prototyping (RP) methods, using ABS resin and support materials. The CAD data exported to the RP system in STL format was prepared by a commercial solid modeling software, SolidWorks. It has been proved that the plastic pulley can successfully replace the existing flow-formed steel product.

Chinese literature once had its splendid era in the Tang and Song Dynasties culminating in Tang poetry and influencing the literatures of its neighboring countries. However, during the past centuries, it has largely been "marginalized" on the map of world literature. On the one hand, large numbers of foreign literary works, especially those from Western countries, have been translated into Chinese, exerting a huge influence on the formation of a sort of modern Chinese literary tradition. On the other hand, few contemporary Chinese literary works have been translated into the major foreign languages. With the help of the rise and flourishing of comparative literature, contemporary Chinese literature has been moving toward the world and had its own Nobel laureate. The author, after analyzing the reasons why Chinese literature has been "marginalized," argues that Chinese literature will develop steadily in the age of globalization. Globalization in China has undergone three steps: first, it has made China passively involved in this irresistible trend; second, the country has then quickly adapted itself to this trend; and third, China has started to play an increasingly leading role in the first decade of the present century. In this way, contemporary Chinese literature and comparative literature studies will steadily develop with the help of the "Belt and Road" initiative.

The K-Ar ages of biotites, obtained from thirteen pelitic schists in the Jeungpyeong-Deokpyeong area, central Ogcheon metamorphic belt, range from 89 Ma to 213 Ma except for one specimen. These K-Ar ages systematically decrease as the distance between the analyzed specimen and the Jurassic or Creataceous granite decreases. The K-Ar ages of b~otites adjacent to the Jurassic and Cretaceous granites are 166 Ma and 89 Ma, respectively. Thus, the biotite ages are interpreted to result from the partial or complete resetting by thermal activities in association with the intrusion of Mesozoic granites, following the regional-thermal metamorphism at Late Triassic to Early Jurassic times.

For survival of human beings clean water is an essential commodity whereas contamination in drinking water threatens to mankind. The main cause of water contamination is social and development activities of human being along with increasing population. The community in the study area has acute shortage of drinking water along with about 40 to 60% has no access to safe drinking water. This study indicates drinking water quality of two major sources of coastal belt of Karachi one is supplied by Karachi Water & Sewerage Board (KWSB) as tap water and the other through groundwater. The physicochemical analysis was carried out by following the standard methods for checking the quality of drinking water. The analyzed results showed that the quality of groundwater was unfit as potable water. The most critical situation was observed as high level of contamination followed by high turbidity and increased salinity levels. TDS in surface water were found 12% above and TDS in groundwater was 20% below the National Drinking Water Quality Standards (NDWQS) of Pakistan as well as the permissible WHO drinking water quality guidelines.

This paper presents development of meander monitoring system base reliable detection at conveyer belt used for materials transport line of steel company. Conventional detection method is losed the confidence, because of the place with bad surroundings of measurement so much that materials production line are completely exposed to dust, moisture and vibration. For the solution of this problem, we developed infrared meander detection system using the infrared sensor array and one chip microprocessor which is available for bad surroundings and inexpensive. The reliability of the system was estimated by experiment.
