Brief Introduction to Language Ecology and Language Instruction  [PDF]
Jun Yang
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.212015
Abstract: Ecology of Language and Language Instruction written by Okazaki Toshio, the professor of Tsukuba University Japan expounds the questions that young people confronted with in the globalization context and the questions in language instruction (foreign language teaching) in a perspective of ecology of language, and proposes to take an Content-Based Instruction for language class so as to develop the learners’ ecology literacy while training their proficiency in language, and to help the learners to take their paths of sustainable development for their lives. This paper intends to introduce this book to Chinese readers so that the Chinese scholars put emphasis on Ecology of Language and Language Instruction.
Service Cooperation Policy in a Dual-Channel Supply Chain under Service Differentiation  [PDF]
Jun Chen, Ying Yang
American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.46036
Abstract:

A service collaboration decision problem in a dual-channel supply chain is studied with the service level and the customer’s acceptance of the Internet channel is taken into consideration. Then the Stackelberg decentralized decision model and the centralized decision model are developed for two settings that the retailer provides the same service level in both channels or not. The conclusion implies that the system profits, the manufacturer’s optimal profit and retailer’s optimal profit are always higher when different services are provided than the same service, and the optimal service level for the direct channel is a little lower than that for the traditional channel under decentralized mode.

A Case of Anesthetic Treatment of Appendicectomy to a Patient under Potato Poisoning  [PDF]
Xi Yang, Jun Li
Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.44029
Abstract:
We reported a case of anesthetic treatment of appendicectomy to a patient under potato poisoning. The overview of potato poisoning has been reviewed in the report and the symptom of the patient under potato poisoning comparing with other appendicitis patients has been described. We highlighted the deference of methodology of anesthetic treatment comparing the patient under potato poisoning with other appendicitis patients.
Study on the Relationship between Economic Growth and Water Pollution in Jiangxi Province—Based on ARDL Model  [PDF]
Jun Yang, Youdong Wen
Journal of Power and Energy Engineering (JPEE) , 2018, DOI: 10.4236/jpee.2018.67004
Abstract: Identifying the key influencing factors of water pollution in Jiangxi Province is vital for formulating effective environmental protection measures. Jiangxi Province is located in the central of China. It plays a very important role in the “Rise of Central China” strategy. In recent years, water pollution in various regions of Jiangxi Province has become more and more serious. Therefore, exploring the main driving factors of water pollution in Jiangxi Province is of great practical significance. In this paper, the Autoregressive Distributed Lag (ARDL) approach is used to study the long-term equilibrium and short-term dynamic adjustment relationship between economic growth and water pollution in cities of Jiangxi Province from 1998 to 2016. The results show that there is a long-term equilibrium relationship between the water pollution index and the actual GDP of the first type of cities. However, due to the difference in the form and parameters of model, the inverted “U-shaped” relationship of the water pollution index and the actual GDP is not always presented. The regional economic growth of the second type of urban areas leads to increase of pollutants. It is obvious that the deteriorating environment has increased people’s living costs and inhibited economic growth. The contradiction between economic development and environmental pollution in the third type of urban areas is most acute. Therefore, in order to effectively protect the environment, local governments should consider all these factors as well as regional heterogeneity in formulating policies.

Continuous Transmission Frequency Modulation Detection under Variable Sonar-Target Speed Conditions
Yang Wang,Jun Yang
Sensors , 2013, DOI: 10.3390/s130303549
Abstract: As a ranging sensor, a continuous transmission frequency modulation (CTFM) sonar with its ability for range finding and range profile formation works effectively under stationary conditions. When a relative velocity exists between the target and the sonar, the echo signal is Doppler-shifted. This situation causes the output of the sensor to deviate from the actual target range, thus limiting its applications to stationary conditions only. This work presents an approach for correcting such a deviation. By analyzing the Doppler effect during the propagation process, the sensor output can be corrected by a Doppler factor. To obtain this factor, a conventional CTFM system is slightly modified by adding a single tone signal with a frequency that locates out-of-sweep range of the transmitted signal. The Doppler factor can be extracted from the echo. Both verification experiments and performance tests are carried out. Results indicate the validity of the proposed approach. Moreover, ranging precision under different processing setups is discussed. For adjacent multiple targets, the discrimination ability is influenced by displacement and velocity. A discrimination boundary is provided through an analysis.
Statistical Recognition Method of Binary BCH Code  [PDF]
Jiafeng Wang, Yang Yue, Jun Yao
Communications and Network (CN) , 2011, DOI: 10.4236/cn.2011.31003
Abstract: In this paper, a statistical recognition method of the binary BCH code is proposed. The method is applied to both primitive and non-primitive binary BCH code. The block length is first recognized based on the cyclic feature under the condition of the frame length known. And then candidate polynomials are achieved which meet the restrictions. Among the candidate polynomials, the most optimal polynomial is selected based on the minimum rule of the weights sum of the syndromes. Finally, the best polynomial was factorized to get the generator polynomial recognized. Simulation results show that the method has strong capability of anti-random bit error. Besides, the algorithm proposed is very simple, so it is very practical for hardware im-plementation.
The Evaluation of Enterprises’ Sustainable Superiority Degree of Technical Innovation Based on DEA Method  [PDF]
Bing Jiang, Lu Yang, Jun Fang
Journal of Service Science and Management (JSSM) , 2008, DOI: 10.4236/jssm.2008.13028
Abstract: The paper at first expounds two new concepts of sustainability degree and superiority degree, and founds a method of DEA of relative efficiency index to rank all decision-making-units having been identified efficient. On the basis of them, the definition and arithmetic are given to analyze them. Then seven input and output techno-innovation indexes which belong to six automobile listed companies from 2002 to 2005 are used to evaluate enterprises’ sustainability degree and superiority degree by vertical and horizontal calculation based on DEA method. At last, we get general conclusions about enterprises’ sustainable superiority degree by weighting calculation.
Measurement of Cooling Effect of Building Environment Greening  [PDF]
Qinghai Luo, Jun Zou, Xiufei Yang
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.37068
Abstract: A series of measurements showed that community greening and trees shading had different degree of cooling effect. The cooling effect of wall greening was related to factors such as heat storage capacity and the orientation of the wall, climatic conditions. As compared to the heat reduced by sheltering the solar radiation, the heat absorbed by plant transpiration had greater cooling contribution. Comprehensive considering environment, technology and economics factors, the building district greening should take trees as the priority. The trees shading can significantly drop indoor temperature and temperature fluctuation, also created better condition for night-time natural ventilation.
