For the vibration analysis of 3-dimensional piping system containing fluid flow, a transfer matrix method is presented. The fluid velocity and pressure were considered, that coupled to longitudinal and flexural vibrations. Transfer matrices and point matrices were derived from direct solutions of the differential equations of motion of pipe conveying fluids, and the variations of natural frequency with flow velocity for 3-dimensional piping system were investigated.

본 논문에서는 근접 전기유도 무선통신 시스템의 표준 기술인 TransferJet 시스템의 BER(Bit Error Ratio) 성능이 분석된다. TransferJet 시스템은 타 무선통신 시스템들과 비교해서 짧은 통신 범위(즉, 무선통신환경에서 높은 보안성), 더 적은 다중경로 왜곡, 그리고 높은 전송률을 제공하는 장점이 있다. 수신신호를 복조하기 위하여 TransferJet 수신단의 역확산기와 복조기에 연판정 결합(SC: soft-decision combining) 혹은 경판정 결합(HC: hard-decision combining)이 적용될 수 있다. 확산계수가 4이상인 경우에 SC 방식은 HC에 비하여 최소 2 dB의 SNR 이득을 제공한다. 또한, 모의실험 결과로부터, 3비트 양자화는 이중-정밀 부동소수점과 거의 동일한 성능을 제공하기 때문에 TransferJet 시스템에서 SC 방식에 대한 최적 양자화 비트는 3비트로 결론지을 수 있다.

In the passive residual heat removal system of a molten salt reactor, one of the residual heat removal methods is to use the thimble-type heat transfer elements of the drain salt tank to remove the residual heat of fuel salts. An experimental loop is designed and built with a single heat transfer element to analyze the heat transfer and flow characteristics. In this research, the influence of the size of a three-layer thimble-type heat transfer element on the heat transfer rate is analyzed. Two methods are used to obtain the heat transfer rate, and a difference of results between methods is approximately 5%. The gas gap width between the thimble and the bayonet has a large effect on the heat transfer rate. As the gas gap width increases from 1.0 mm to 11.0 mm, the heat transfer rate decreases from 5.2 kW to 1.6 kW. In addition, a natural circulation startup process is described in this paper. Finally, flashing natural circulation instability has been observed in this thimble-type heat transfer element.

본 연구의 목적은 첫째 대학의 평가제도, 교육지원, 인적자원등과 같은 내부지원 요인이 기술이전 사업화 활동에 종사하는 관계자들의 기술이전 사업화 의욕에 영향 요인 인지 밝히고자 하였다. 둘째 이러한 내부 요인과 기술이전사업화 의욕의 인과관계에서 사회적 지지의 조절효과를 검증 하고자 하였다. 위 연구 내용을 분석 하기 위해 전국 40개 대학의 기술이전 사업화 조직에서 해당업무에 종사하는 산학교수, 직원을 대상으로 설문조사를 하였으며, 총160부를 배부하여 145부를 회수하였다. SPSS Statistics 22.0을 이용하여 분석한 결과는 다음과 같다. 첫째, 대학 내부요인, 즉 업적평가, 교육지원, 인적자원 모두 기술이전사업화 의욕에 유의한 영향을 미쳤다. 둘째, 대학내부요인과 기술이전 사업화 의욕과의 관계에서 사회적 지지의 조절효과를 분석한 결과, 업적평가와 기술 이전 사업화 의욕 관계에서 사회적 지지는 유사조절효과를 나타냈다. 하지만 교육지원 및 인적자원과 기술이전 사업화의욕 관계에서는 사회적 지지의 조절효과는 나타나지 않았다. 이 연구결과를 바탕으로 대학에서 기술이전 사업화 활동을 하는 사람중심의 지원정책수립에 시사점을 제공 하고자 한다.

During the transformation of the agro-technology extension in rural China, many new Policy experiments are emerging to rebuild the lost linkages and to improve technology transfer with the system and among systems. Applying the Triple Helix Model of academy-agriculture-government relations, this paper explores a new pattern of technology transfer with the case of BaojiCity. The authors interpret the mechanism of 'Courtyards for Agro-experts', as well as the comparison between different types of courtyards. This article concludes that the Triple Helix in the agro-sector improves technology transfer and accelerates knowledge-based regional development. In the interest of farmers there should also be concern over reducing inequity the reform.

Along with the international technology transfer market, as the domestic market grows, more professional technology analysts are needed and it became more necessary to investigate the qualification of those experts to cope with growing market. In this study, the current working condition of those experts is described, qualification system is analyzed and more realistic suggestions on the system to activate the market and to encourage the experts will be introduced. The study was performed based on the questionnaire sent to the person who works in related fields, such as industry, technology transfer center, universities, etc.

This paper proposes an experimental optimization method for a wireless power transfer (WPT) system. The power transfer characteristics of a WPT system with arbitrary loads and various types of coupling and compensation networks can be extracted by frequency domain measurements. The various performance parameters of the WPT system, such as input real/imaginary/apparent power, power factor, efficiency, output power and voltage gain, can be accurately extracted in a frequency domain by a single passive measurement. Subsequently, the design parameters can be efficiently tuned by separating the overall design steps into two parts. The extracted performance parameters of the WPT system were validated with time-domain experiments.

This Study focused on the process of technology transfer for the aircraft development program by the strategic alliance. Especially, this study showed how the learning firms absorb new technology from the foreign leading company. This case study concludes that teachability, asset specificity, relation capital with partner, information sharing system in organization and knowledge base are key factors for absorbing the new technology from the technology leading partner.
