Its research and analysis include six parts, namely, an overall analysis, an analysis of English demand according to the kind of employment units, according to trade, according to job, according to specialty and the five skills of ＂listening, speaking, reading, writing and translation＂. The supplied data tell the reality of the current English demand of employment units in China, which would also reflect the trend in the coming few years. The analysis of the data embodies the reality of college English teaching, discusses its advantages and disadvantages and puts forward reasonable suggestions on college English teaching and evaluation system.展开更多

Using the single- epoch precise point positioning （PPP） method and the appropriate positioning flow, we process GPS data from six IGS （International GNSS Service） sites （e.g., MIZU, TSK2, USUD, MTKA, AIRA and KSMV） located in Japan and obtain the positioning results with centimeter scale precision. The displacement time series of the six sites are analyzed using the least squares spectral analysis method to estimate deformations caused by the Mw9.0 mainshock and the Mw7.9 aftershock, and the cumulative displacements after 1 day. Mainshock displacements at station MIZU, the nearest site to the mainshock in the North （N）, East （E）, and Up （U） directions, are -1.202 m, 2.180 m and -0.104 m, respectively, and the cumulative deformations after 1 day are -1.117 m, 2.071 m and -0.072 m, respectively. The displacements at station KSMV, the nearest site to the Mw7.9 aftershock in the N, E and U directions, are -0.032 m, 0.742 m and -0.345 m, respectively. The other sites obviously experienced eastern movements and subsidence. The deformation vectors indicate that the horizontal displacements caused by the earthquake point to the epicenter and rupture. Elastic bounds evidently took place at all sites. The results indicate that the crustal movements and earthquake were part of a megathrust caused by the Pacific Plate sinking under the North American Plate to the northeast of Japan island arc.展开更多

Methods and Materials： A randomly sampled population of 280 students and 12 managerial staff of sport and medical units participated in the descriptive study. Responses to a validated questionnaire provided the source of data. A test-retest reliability coefficient （r） = 0.80. Data were analyzed with simple percentages and Chi-square at 〈 0.05 alpha level. Results： All the respondents in medical centre and sport unit oriented the students on the available medical services and facilities on campus： availability of first aid services, treatment services for complicated injuries （inpatient）, referral services for specialized care, financial support during hospitalization. Complementary results from the students showed that the majority of the respondents （50%） strongly agreed that medical centre was available in the Campus, and 36% strongly affirmed to availability of first aid services. Thirty four percent of the respondents strongly agreed to the availability of treatment services, while 40% of the respondent agreed to the availability of free medical services. The study revealed that there was a significant relationship between efficient medical services and students＇ participation in sports. Conclusion： All medical services were available but students perceive the services as inefficient which implies poor or non utilization.展开更多

It is widely spreading the concept of Old Town as Natural Shopping Centre： with this word, we define commercial complex and not homogenous places, developed over time without programming unit. designed as a unique space, which fall within a certain urban perimeter, work together as a business, financial administration, facilities and service all coordinated by a common policy development. In order to recover the vitality of the consolidated tissue of the city of Parma, the Town Council has started to study its historic centre as Natural Shopping Centre, relying on the potential inherent in the existing commercial streets.展开更多

To realize this technique, two challenges—polycrystalline nucleation on the crucible wall and dislocation multiplication inside the crystal—needed to be addressed. Numerical analysis was used to develop solutions for these challenges. Based on an optimized furnace structure and operating conditions from numerical analysis, experiments were performed to grow monocrystalline silicon using the single-seed casting technique. The results revealed that this technique is highly superior to the popular high-performance multicrystalline and multiseed casting mono-like techniques.展开更多
