An analytical model of liquid sloshing is developed to consider the energy-loss effect through a partially submerged porous baffle in a horizontally oscillating rectangular tank. The nonlinear boundary condition at the porous baffle is derived to accurately capture both the added inertia effects and the energy-loss effects from an equivalent non-linear drag law. Using the eigenfunction expansion method, the horizontal hydrodynamic force (added mass, damping coefficient) on both the wall and baffle induced by the fluid motion is assessed for various combinations of porosity, submergence depth, and the tank's motion amplitude. It is found that a negative value for the added mass and a sharp peak in the damping curve occur near the resonant frequencies. In particular, the hydrodynamic force and free surface amplitude can be largely reduced by installing the proper porous baffle in a tank. The optimal porosity of a porous baffle is near P=0.1.

41개국 34개 산업의 부가가치수출 RCA를 계산하고 각국 각 산업의 경쟁력을 평가하였다. 중국의 성장속도가 한국보다 빠른 것은 사실이지만 한국의 수출을 대체 또는 추월하고 있다는 증거는 미약하다. 수출 주력산업에서의 일본과의 경쟁력 격차가 확대되고 있다는 주장 또한 설득력이 미흡했다. 전세계 국가-산업의 패널분석의 시사점은, 대 세계 경쟁력을 유지하는 방편으로 산업 내 교역 특히 중간재 교역이 활성화되면서 부가가치 RCA와 총수출 RCA 간에 격차가 발생한다는 것이다.

Purpose - The purpose of this paper is to provide a political registration point for analyzing the economic impacts on the national economy from the REITs distribution industry in our country. The REITs distribution industry was introduced in 2001 to accelerate the corporate restructuring process and advance the real estate market. During its establishment, the REITs distribution industry faced difficulties; however, the industry grew rapidly through interest from institutional investors, thus mitigating the establishment problems by 2006. In Korea, more than 108 REITs were operating as of the end of June 2015. REITs contribute significantly to the national economy. The economic impacts on the national economy of the REITs distribution industry was analyzed using input-output (I-O) analysis with respect to production, imports, value-added, and employment. Research design, data, and methodology - The research used an I-O analysis of the activities of the REITs distribution industry in the national economy. The I-O analysis methodology analyzes the economic effects that influence other industries with respect to one unit of external investment. The data for this analysis were the I-O table of 2013 as published by the Bank of Korea in 2014. Results - The findings of this study are as follows. First, if an external input to the REITs distribution industry is 1 won, the overall impact of the product is 1.3869 won, the import induction is 0.0002 won, and the value-added induction is 0.7656 won. A new investment of 659.9 billion won into the REITs industry was estimated to produce a gross effect of 915.2 billion won. Second, if an external input to the REITs distribution industry is 1 billion won, the employment-inducing effects are estimated at 19.6394 individuals. The employment-inducing coefficient of 19.6394 for the REITs distribution industry indicates that the industry created significant employment-more than other industries-because the coefficient was 2.2 times the 2013 industry average employment-inducing coefficient of 8.8. Third, the investment effects of the REITs distribution industry on production induction, value-added induction, and employment induction are assumed to be large in business support services, financing, communications and broadcasting, and professional, scientific, and technical services. Conclusions - The REITs distribution industry was analyzed as having a strong employment inducing, high value added effect. The REITs distribution industry is an excellent alternative for the government authority to create multilateral jobs. Because the REITs distribution industry has a significant positive impact on the national economy, it should be developed. However, the I-O methodology has restrictions with respect to the fixation and timing of the input coefficient. Follow-up research is expected to supplement the analysis method at a specific point in time.

The electrical property of polymer matrix composites with added carbon powder is studied based on the temperature dependency of the conduction mechanism. The temperature coefficient of the resistance of the polymer matrix composites below the percolation threshold (x) changed from negative to positive at 0.20 < x < 0.21; this trend decreased with increasing of the percolation threshold. The temperature dependence of the electrical property(resistivity) of the polymer matrix composites below the percolation threshold can be explained by using a tunneling conduction model that incorporates the effect of the thermal expansion of the polymer matrix composites into the tunneling gap. The temperature coefficient of the resistance of the polymer matrix composites above the percolation threshold has a positive value; its absolute value increased with increasing volume fraction of carbon powder. By assuming that the electrical conduction through the percolating paths is a thermally activated process and by incorporating the effect of thermal expansion into the volume fraction of the carbon power, the temperature dependency of the resistivity above the percolation threshold can be well explained without violating the universal law of conductivity.

이 연구에서는 Pulic 등의 부가가치 지적계수(Value Added Intellectual Coefficient, VAICTM) 모형을 이용하여 한국의 은행, 증권사, 보험사 등의 지적자본 효율성을 측정하고, 지적자본을 구성하는 인적, 구조적, 물적 자본과 금융기관의 경영성과 간의 상관관계 및 유의성을 분석하였다. 분석 결과 국내 금융회사중 부가가치 지적계수(VAIC) 및 인적자본 효율성 계수(HCE)는 은행, 보험, 증권 순으로 높았다. 한편, 아시아 주요국 및 세계 10대 은행들과 비교해 볼 때 한국을 포함한 선진국 은행들이 개도국 은행보다 VAIC와 HCE가 높은 것으로 나타났다. 다만, 한국은 호주 등에 비하여 VAIC 및 HCE가 낮은 수준인 것으로 나타났으며 최근 들어 그 수치가 하락세에 있는 것으로 나타났다. 한국 금융서비스 분야의 국제경쟁력 제고를 위하여 노력할 사항을 제기하고 있으며 한국 금융산업이 해외시장 진출을 추진하는데 있어 시사점을 제시하고 있다.
