This study investigates the main characteristics of Chinese automobile industry based on the technology learning, architecture theory and cluster. As a case study sample, we chose three most representative automobile firms from three main cities in China, FAW from northern part of China, SAIC from middle part of China, and BYD from southern part of China. According to the research findings, FAW has equipped self-production ability in virtue of political support but felled behind in future transportation due to lack of convergence with local cluster. In case of SAIS, similar phenomenon happened in spite of highest purchasing power of shanghai. BYD has achieved great quantum jump through the aggressive investment strategy in electric vehicle even though there are still many technological learning and experience to be cumulated. Overall, this research extends the current literature on key roles (technological learning, architecture, and cluster features) in the automobile industry growth by suggesting their crucial aspects in knowledge management and strategic planning to a newly emerging market, China, and sheds light on the relationship between regional characteristics and automobile growth.

The renewable resource are getting more attentions with increased concerns on the depletion of fossil fuels and several environmental issues like emission problem. Wind power is a representative option among several renewable sources and the generation capacity using wind power is being increased. However, the wind generation is so volatile on its output characteristic, so it is required to assess the grid impact of wind power generation by measuring the fluctuation effect more precisely. This paper proposes the method for measuring the generation output according to IEC 61400-21(Measurement and assessment of power quality characteristics of grid connected wind turbines) to assess the power quality of wind turbine generation. In addition, it shows an application case to a small-scale wind power generator. In the case study, it suggests a structure design of the proposed measurement instrument both on hardware and software aspects, which is composed of a remote monitoring & data analysis program and an FPGA based real-time signal processing device.

Facial nerve palsy is not a serious disease, but it can be both upsetting and disabling for patients. More than half of the lesions of facial nerve palsy fall into the category termed Bell's palsy. It is very rare to find a representative case of bilateral Bell's palsy. Here we report the changes of infrared thermographic findings in bilateral Bell's palsy treated with a stellate ganglion block (SGB). A 45-year-old female patient who had a right facial palsy which developed 2 weeks before. Steroid administration and acupuncture was not effective and so she was referred to pain clinic. The right facial palsy was cured after 19th right SGB. Twenty eight days after the onset of the right facial palsy, left facial palsy also developed and cured completely with a left SGB. Serial infrared thermograms were performed. The hypothermias on the affected side improved symmetrically by the end of the treatment.

The typhoon wind characteristics designing for buildings or bridges located in complex terrain and typhoon prone region normally cannot be achieved by the very often few field measurement data, or by physical simulation in wind tunnel. This study proposes a numerical simulation procedure for predicting directional typhoon design wind speeds and profiles for sites over complex terrain by integrating typhoon wind field model, Monte Carlo simulation technique, CFD simulation and artificial neural networks (ANN). The site of Stonecutters Bridge in Hong Kong is chosen as a case study to examine the feasibility of the proposed numerical simulation procedure. Directional typhoon wind fields on the upstream of complex terrain are first generated by using typhoon wind field model together with Monte Carlo simulation method. Then, ANN for predicting directional typhoon wind field at the site are trained using representative directional typhoon wind fields for upstream and these at the site obtained from CFD simulation. Finally, based on the trained ANN model, thousands of directional typhoon wind fields for the site can be generated, and the directional design wind speeds by using extreme wind speed analysis and the directional averaged mean wind profiles can be produced for the site. The case study demonstrated that the proposed procedure is feasible and applicable, and that the effects of complex terrain on design typhoon wind speeds and wind profiles are significant.

To decompose carbon dioxide, which is a representative greenhouse gas, a plasma torch was designed and manufactured. To examine the characteristics of carbon dioxide decomposition via plasma discharge, a case wherein pure carbon dioxide was supplied and a case wherein methane and/or $TiCl_4$ were injected as additives were investigated and compared. The carbon dioxide and methane conversion rate, energy decomposition efficiency, produced gas concentration, carbon monoxide and hydrogen selectivity, carbon-black and $TiO_2$ were also investigated. The maximum carbon dioxide conversion rate was 28.9% when pure carbon dioxide was supplied; 44.6% when $TiCl_4$ was injected as am additive; and 100% percent when methane was injected as an additive. Therefore, this could be explained that the methane injection showed the highest carbon dioxide decomposition. Furthermore, the carbon-black and $TiO_2$ were compared with each commercial materials through XRD and SEM. It was found that the carbon-black that was produced in this study is similar for commercial materials. It was found that the $TiO_2$ that was produced in this study is suitable for photocatalyst and pigment because it has mixed anataze and rutile.

Facial nerve paralysis is a common pain clinical diagnosis. But ipsilateral or contralateral recurrent facial paralysis is found in about 2.6~19.5% of facial paralysis and especially bilateral facial paralysis is rare. While idiopathic facial paralysis is the most common diagnosis, a comprehensive evaluation must be completed prior to this diagnosis in patients with bilateral facial paralysis. A representative case of bilateral alternating facial paralysis treated with stellate ganglion block (SGB) is presented. A 57 years old male patient who had the onset of a right facial paralysis 7 months ago visited pain clinic. Five months after the onset of right facial paralysis, as it was improving, he developed a left facial paralysis. He had history of hypertension, diabetus mellitus and pain episode on mastoid process before facial paralysis developed. Electrical test showed incomplete neuropathy on both side and computed tomography (CT) scan was normal. He was treated with SGB, physical theraphy and aspirin medication. After 25 times SGB, he was recovered almost completely.

Entertainment Industry, with high productivity of added value, is noticed as a major industry leading global economy. Thus the government has been constantly attempting to devise various plans for developing entertainment industry, but the plans are mostly come out according to currently faced issues rather than considering the whole industry interior interaction. We are mainly objective to find a ground for estimating the current entertainment industry status. For this, we borrowed the concept of 'maturity' from various capacity maturity estimation tools. We also analyzed Korean film industry as a representative entertainment industry case to find what and how government intervention has affected on the industry.
