With the arrival of knowledge economy era and the shortening of product life cycle, information technology and the rapid development of e-commerce with each passing day, and customer gradually increasing expectations, the competition among enterprises are gradually entering the supply chain competition, Now enterprises have begun to realize that effective supply chain management, which would have to assess supply chain performance. However, most of the evaluation methods used in our country using expert analysis to evaluate the contractor's financial indicators to determine the final contractor. This method is not only too subjective, but also cuts off the correlation between the indicators. A quantitative management innovation classified performance model of supplier performance evaluation based on clustering and K-NN classification is proposed to classify suppliers. Then on the basis of above analysis, the contractor of misclassification is identified by the K-NN method. Finally, an evaluation and selection case is presented to verify the practicability and effectiveness of the model. The method not only overcomes the above shortcomings, but also reflects the contractor's comprehensive level objectively and fairly. The results show that it can provide an important reference for the fair and impartial evaluation of the project contractor as an important method for decision makers to select the contractor.

The result shows that the model could reflect the capabilities of the supplier objectively and fairly and achieve an effective evaluation on supplier performance and which plays a role of illumination for supply chain design.

PurposeIn China the maturity of the industrial development has the demonstration and reference implications for how to achieve enterprises competitiveness among the developing industries in a country. With the development of globalization, how to improve the enterprises competitiveness has became a serious problem to be solved for Chinese enterprises. The management innovation is reasonable and appropriate to solve this problem. Compared with the independent innovation, adoptive management innovation has become the main way for enterprises to fulfill the management innovation and change the management styles under the open economy condition. The research strives to reveal the “black box” in the management innovation adoptive process and give an answer to a series of questions, such as “what is the role of entrepreneurs in management innovation adoptive process?”Design/methodology/approachExploratory case study approach is taken to find the entrepreneurs' role in management innovation adoptive process of Chinese traditional industry.FindingsThis paper constructs the adoptive management innovation model from three dimensions, using exploratory case technique, which explores the key factors and mechanism of realizing management innovation adoption. Through the exploratory case analysis to verify the viewpoint which is proposed by the model: entrepreneurs played a leading role in the adoptive management innovation of non‐procedural process, and the role is the result of the mixed function of the external and internal environment. Entrepreneurs analyze and explore the new problems and opportunities, and their own experience and ability determine the cognition and explore degree towards these problems directly; entrepreneurs' integration ability of resources can be approved and accepted after the new practice has been proposed and become mature. Entrepreneur long‐term shaping on organizational resources determines whether the management innovations introduction would be really integrated into enterprise management system. The entrepreneur's typical behavior on “integration, learning and shaping” is the foundation and guarantee of adoptive management innovation, which have connective effect on adjacent stages.Originality/valueThe article describes Haier BPR process of adoptive management innovation and the adoptive management innovation mode, and analyzes the effect of entrepreneurs' role on adoptive management innovation of China's color TV industry. The Chinese color TV industry as the maturity industry has the demonstration and reference implications for how to achieve enterprises competitiveness in Chinese developing industries.

PurposeThe color TV industry in China has become a mature industry. Its development demonstrates and provides reference implications for how developing industries within a country can achieve a technological leap. This paper aims to address this issue.Design/methodology/approachAn exploratory case study approach is taken to find the key factors in the technological catch‐up of China's traditional industry.FindingsIn the study it is found that China's color TV industry, as a mature traditional industry, has four‐dimensional key factors affecting the catch‐up of technology in the flat‐panel stage: market; merger and acquisition; international cooperation innovation for patent; and the roles of internal reform. “Market” is the window of opportunity and challenge; “merger and acquisition” is the key factor for making the patent convert from external mode to internal mode by deviant‐track. The “international cooperation innovation for patent” is also a key factor to ensure achievement of technology catch‐up and sustainable technological innovation. The role of internal reform promoter is the key factor in the technological catch‐up process in which taking entrepreneur as the core.Originality/valueThe article describes Changhong's flat‐panel TV technology catch‐up mode, analyzes four‐dimensional key factors affecting the technology catch‐up of China's color TV industry; the Chinese color TV industry as mature industry; and discusses which developments have demonstrated how to achieve a technological leap in developing industries.

Underwater interfacing technique is the key technique of the underwater vehicle. Now the technique is mainly used in the submarine rescue. Based on the structural characteristics of the model of BSAV-Ⅰand the interfacing apparatus with the manipulators which are made by Harbin Engineering University, a group of equations were defined and solved based on the six freedom motion of the model.

Except this, the research on simulation system of the interfacing apparatus of the underwater vehicle based on VR can test the docking strategy, find the problems in docking and improve the structure of the interfacing apparatus.

Our previous studies showed that electroacupuncture (EA) could inhibited radiant heat induced pain and acute or chronic inflammatory pain in rats. In the present study, we observed whether EA with different frequencies could suppress neuropathic pain.L5/L6 nerve ligation model was used to assess the effect of EA on neuropathic pain. Mechanical allodynia was represented by 50% withdrawal threshold, while cold-induced ongoing pain was detected by the number of paw lift in 5 min when the rat was put on a 5 degrees cold plate. Han's acupoint nerve stimulator (HANS) was connected to needles inserted into acupoints "jiaji" and "Zusanli" in both sides. The parameters were: (intensity: 0.5-1-2 mA, 10 min each; frequency 2 Hz or 100 Hz; pulse width: 0.6 ms for 2 Hz, 0.2 ms for 100 Hz).EA of both 2 Hz and 100 Hz could relieve the mechanical allodynia, where 2 Hz could induce the effect with shorter latency; they could also relieve the cold-induced ongoing pain, where the effect of 2 Hz outlasted the EA session by up to 48 h after repetitive stimulations over several weeks; a significant relieving effect on cold-induced ongoing pain could also be induced by needle insertion without stimulation.EA could relieve neuropathic pain, the analgesic effect of 2 Hz EA is higher than 100 Hz EA.

Peripheral electrical stimulation (PES) has been utilized to manage chronic pain associated with nerve injury. However, the data on clinical effectiveness are conflicting and the neurophysiological mechanism is not well known. This study was designed to assess whether PES relieved neuropathic pain and its possible mechanisms. The neuropathic pain model was made with lumbar 5th (L5) and 6th (L6) spinal nerve ligations in rats. Nociceptive responses of the rats were assessed by the cold plate test (the number and duration of paw lifts that occurred in 5 min on a 5 +/- 1 degrees C cold plate). PES with a frequency of 2 Hz and at increasing strengths was given for 30 min via stainless-steel needles inserted into standard acupoints on the leg and back, respectively. Immunochemistry was used to examine the immunoreactivity of the NMDA receptor 1 (NR1) subunit in the spinal cord dorsal horn. The results are as follows: (1) PES relieved neuropathic pain and the effect was blocked by 1.0 mg/kg naloxone. (2) The effect of one session of PES lasted up to 12 h. (3) Repetitive PES showed a cumulative effect and no tolerance was observed. (4) There was a significant increase of NR1 immunoreactivity in the superficial laminae of the spinal cord of neuropathic pain rats as compared with naive rats. This increase could be reversed by repetitive 2 Hz PES. These results suggest that PES can relieve neuropathic pain, and that mu-opioid receptors and NMDA receptors are involved in the effect of PES.
