본 연구는 항공화물운송사, 물류기업, 공항관리당국 등이 국경 간 전자상거래 항공화물 운송·처리와 관련된 각종 계획 및 전략을 수립하고 개선하는 데에 있어 유의한 시사점을 제시하기 위해, 인천국제공항의 국경 간 전자상거래 항공화물의 네트워크 및 화종에 대한 분석을 수행하였다. 본 분석을 위해 한국무역통계진흥원으로부터 2014년부터 2019년까지의 수출입 신고데이터를 수집하였으며, 사회연결망분석(SNA) 도구인 NodeXL을 통해 네트워크 분석 및 포지셔닝맵 분석을 통한 화종 분석을 수행하였다. 분석 결과, 네트워크 규모의 확장, 소수 연결망 위주로의 화물 집중화, 경박단소(輕薄短小) 특징의 심화, 의약품 등 온도민감성 화물의 증가 등의 특징이 분석되었다. 이에 따라, 의약품전용창고 등 온도민감화물 전용시설 확충, 기존 화물터미널의 전면적인 시설 개선, 항공 네트워크의 개편 등이 필요할 것으로 판단된다. Purpose : This study aims to analyze network and types of cross-border e-commerce air cargo in Incheon international airport in order to provide significant implication that enables air cargo carriers, logistic companies, and airport management authorities to establish and improve various plans and strategies. Research design, data, methodology : This paper analyzes the trade performance of cross-border e-commerce by import/export, target import and export countries, and imports and exports by using official import and export statistics from 2014 to 2019 that were collected from Korea Trade Statistics Promotion Institute. Additionally, this study analyzes the network by utilizing NodeXL which is one of a Social Network Analysis (SNA) tools, Herfindahl-Hirschman Index and also does a type of freight though the analysis of positioning map. Results and Conclusions : In freight network analysis, phenomenon such as an extension of the network scale, freight concentration leading to an oligopoly in network, and the expansion of export cargo to China are found. In the type of freight analysis, an intensified trend in the type of freight that is lightweight, thin, short, and small, and the increase in temperature-sensitive cargo such as pharmaceutical products, processed livestock products, and processed agricultural products are identified.

The performance study shows the result using two different methods which are used to control missile or aircraft. One is the Thrust Vector Control(TVC) method for the aviation of next generation and the other is the present effective Shroud Jet-vane System(SJVS) method for the satellite effector development. The research was done through the performance estimation using the numerical simulation analysis, the modelling, the performance measuring using the model, the investigation of the flow visualization and aerodynamic performance with the enforced power to the vane and the result comparison.

This paper presents the lousing characteristics and the time. response of ultrasonic focusing transducer which is a coupled system with an electromechanical and an acoustical component. The Finite Element Method and the Hybrid Type Infinite Element Method are applied for the analysis. The position of the focal points and the resolutions is obtained from the loosing characteristics and the time response. It is found that the transducer with the damper, which stabilizes the displacement of the radiation surface, gives a better resolution. In conclusion, the results could be applied to the design and the performance analysis of the ultrasonic focusing transducer.

스피커 드라이브 설계에 있어 부품 단계의 물리적 특성과 자기회로부의 전자장 유한요소 해석 결과를 적용하여 드라이브의 TS 파라미터, 주파수 응답 특성 및 전기 입력 임피던스 특성을 예측할 수 있는 기법을 제안한다. 중량 감소 및 비대칭 자속 밀도 분포를 개선하기 위한 설계에 있어서 주파수 응답 특성과 전기 입력 임피던스 특성의 예측 결과는 실측치와 잘 일치하였으며, 비대칭 자속 밀도 분포의 해석을 통하여 2차 고조파 왜곡 특성의 향상 등에 응용될 수 있을 것이다. 제안된 기법은 자기회로부 설계에 있어서 시행 착오의 과정을 줄이는데 이용되어 질 것으로 기대되며, 또한 설계 초기단계에서 목적의 드라이브 구성 부품을 선택하는 지침을 제공하는데 이용될 수 있을 것이다. The prediction method of TS parameters, frequency response, and electrical input impedance is proposed with physical properties of parts and results of electromagnetic FEA(Finite Element Analysis) in a loudspeaker driver design. In design for weight reduction and improvement of flux density asymmetry, the prediction results are well coincided with measurement ones. As the applications, it can be applied in design for improvement of the $2^{nd}$ harmonic distortion with flux density distribution analysis. The proposed method is expected to be utilized for reducing trial-and-error process in electromagnetic parts design. It can also be used for providing guidelines for parts selection in the early stages.

The thermoacoustic refrigerator has not only considerable feasibility but also commercial usability, because it has high reliability, lower vibration, no moving part, and can easily be constructed. So A thermoacoustic refrigerator, using a resonant standing acoustic wave, has been built. It employs a loudspeaker to sustain a standing wave in a resonance tube. in the air or nitrogen-filled tube, The stack of plates was along strip of 8cm-wide, 0.075mm-thick plastic sheet(Mylar), spirally wound to make a 40mm-diameter assembly 80mm long. and two heat exchanger are installed. The interaction of the compressed and expanded gas in the channels of the stack with the surface generates heat transport. In this study, the description of thermoacoustic refrigerator and the performance measurements using Helium gas were presented.
