The world's major countries have focused on the renewable energy industry as the solution to climate change and the energy crisis. Nevertheless, there are no studies on the economic effects of the renewable energy industry. This study analyzed the economic effects of Korea's renewable energy industry by using the 2010 Input-Output Table. It is estimated that Korea's renewable energy industry made a production-induced effect of 2.0262 won, and a value-added-induced effect of 0.6138 won through an increase in output growth of 1 won, and an employment-induced effect of 2.3046 labors through an increase in output growth of 1 billion won. Both the effect ratio and the response ratio were greater than 1, which means the renewable energy industry is an intermediate manufacturing industry whose forward linkage effect and backward linkage effects are large. These results show differences with previous studies that classified electricity sector and renewable energy industry into final primary production industries. It is expected that the economic effects of the renewable energy industry will become greater in the future. Therefore, research on statistics related to the renewable energy industry is needed for more precise analysis.

본 논문은 세계산업연관표의 전후방연쇄효과를 이용하여 2000년부터 2014년까지의 한국, 중국, 일본의 1차 산업의 생산유발효과를 비교 분석하였다. 1차 산업의 산업영향력에 관한 연구는 활발히 진행되어 왔으나, 본 논문은 1차 산업 분야에 대한 한국, 중국, 일본의 산업연쇄효과의 차이에 대한 연구라는 점에서 의미가 있다. Fisher(1939)와 Clark(1957)의 1차 산업 분류에 따라 1차 산업을 농림축산업, 임업, 수산업, 광업으로 분류하였다. 분석방법으로는 세계산업연관표를 이용하여 한국, 중국, 일본 3국간 산업연관모형을 만든 후 비교분석하는 것이다. 본 연구의 결과에 따르면, 농림축산업, 광업은 한국, 중국, 일본 각 국가별로 전 후방 연쇄효과에 유의한 차이가 있었고 임업과 수산업의 경우 한국, 중국, 일본의 전 후방 연쇄효과에 부분적으로 유의한 차이가 있었다. 1차 산업의 산업의존도 변화를 4차 산업혁명의 시대에 산업의 전방연쇄효과와 후방연쇄효과를 IO 분석을 통해 각 국가별로 비교함으로서 향후 1차 산업이 나아가야할 방향을 제시하였다.

This paper estimate and analyze the economic effect of the port industries as well its production inducement coefficient, effect ratio and response ratio using above-mention input-output analysis. The results of analysis is that the production inducement effects and the forward and backward linkage effects of port industries sectors are evaluated low evaluations. This results is not the port industry doesn't have low effects and low contributions to Korea economy, port industries are more used in the field of export and import sectors than domestic demand and supply sectors. Accordingly, the import inducement coefficients of shipping industry is most high among the 404 detailed sectors.

본 연구에서는 태양광 패널 청소 로봇이 진공 패드 압력을 이용하여 경사진 패널 위를 미끄러짐 없이 효율적으로 주행하는 방법을 제안한다. 이 방법에서는 로봇을 경사로 패널에 고정시키기 위해 로봇 발에 부착된 고무 패드의 압력을 진공으로 만들게 된다. 구동 방식으로 Linkage 매커니즘을 적용하여 미끄러짐을 방지함과 동시에 중량을 감소하여 소모전력을 낮추는 방법을 제안하였다. 로봇의 안전한 구동을 위하여 솔레노이드 밸브, 근접 센서, 엔코더를 사용하여 로봇의 움직임을 감지하며, 주행할 때 고무 패드의 압력을 제어하여 안전한 경사로 주행을 가능하게 하였다. 로봇의 전진 동작을 위하여 다중의 솔레노이드 밸브들의 동작 시퀀스를 완성하여 양쪽 발에 부착된 6개의 진공패드가 진공 및 대기압을 정확하게 형성 할수 있도록 제어하여 이동 중 미끄러짐 없이 전진할 수 있게 하였다. 마지막으로 주행 및 회전 실험을 통해 36도의 태양광 패널에서 직진 및 회전 동작을 수행할 수 있음을 확인하였다.

This study attempts to analyze the economic impact of the service robot industry using Input-Output analysis, which is conducted based on Demand-driven model, the Leontief price model, the Backward and Forward Linkage Effects, and the Exogenous Methods. In a Demand-driven model analysis, we can conclude that the service robot industry contains characteristics of both the manufacturing industry and the service industry, which causes a positive impact on the overall industry by compensating for the weaknesses of the two industries. The Leontief price analysis indicates when wages in the service robot industry increase, prices related to robot manufacturing also increase. Also, when profits in the service robot industry increase, prices related to service provision increase, too. The Backward and Forward Linkage Effects analysis shows that the service robot industry is highly sensitive to the current economic condition and has a great influence on the service industry. The service robot industry can highlight the aspect of service characteristics when the manufacturing industry is in recession and vice versa. In addition, the service robot industry can be regarded as a value-adding and domestic economy promoting industry which utilizes knowledge of information and communication technologies. It is important to foster the service robot industry in South Korea, which is in economic recession to provide an opportunity to stimulate the growth of both service and robot industries.

In these days, the interest on medical industry is increasing around the world. This paper attempts to estimate the economic effects of the medical and measuring instrument industry through the Input-Output Analysis. Especially, 78*78 Sector Tables were used as the first analysis tool. So then, 79*79 Sector Tables adjusted were used for that industry. The main analysis tools of this study are comparing and analyzing backward and forward linkage effect, the induced effect of the self industry and other industries and the induced coefficients such as products, value-added, employee's pay, sales surplus, employment. According to the result of analysis, the medical and measuring instrument industry has great economic impacts which affects the major macroeconomic factors such as production and backward linkage effect. And the induced effects of the self medical and measuring instrument industry are significant compared to other industries in aspects of production, employee's pay and sales surplus.

A haptic hand controller operated by the user's hand can receive information on position and orientation of the hand and display force and moment generated in the virtual environment to the hand. This paper presents a design method for KU-HHC, 6 DOF Korea University-haptic hand controller, which allows separation of workspace from linkage mechanism in consideration of the efficient user operation. First, the 3 DOF mechanism in which all the actuators are mounted on the fixed base is developed by combining a 5-bar linkage and gimbal mechanism. Then, the 6 DOF HHC is designed by connecting the two 3 DOF devices through a handle. This paper presents the forward and inverse kinematics for this device and Jacobian analysis. Improvement of the kinematic characteristics using performance index is also discussed. The hand controller KU-HHC based on this design concept and kinematic analysis was manufactured and shows excellent performance.

As the climate crisis intensifies, the need to improve the climate resilience of developing countries is ever increasing. Hence, the international community is seeking ways to effectively conduct climate technology transfer by linking the projects with financial mechanisms. However, commercialization of climate technology in developing countries is no easy feat as comprehensive knowledge on the target country is a prerequisite for seeking a suitable technology-financial linkage measure. Hence, in-depth discussions on effective climate technology and financial linkage measures have become an important global agenda, and South Korea, as a country with long experience in climate technology transfer, and a strong ecosystem for public climate technology, should step forward to take up a leading role. Against this backdrop, this paper proposes strategies and implementation measures for linking funds from the Multilateral Development Banks (MDB) with Korea's Public Climate Technology (PCT) by examining several key areas of R&D, international cooperation, and technology commercialization.

본 연구는 1996년부터 2011년까지 투입산출표를 이용하여 해당 기간 동안 한국의 ICT 산업과 자동차 산업의 산업연쇄효과 및 경쟁우위를 비교하였다. 국제표준산업분류(ISIC Rev.4)에 따라 ICT 산업을 분류하여 범위를 명확히 하였으며, 제품의 특성, 혁신주기에 따라 ICT 산업 내 제조업과 서비스업, 그리고 자동차 산업 내 제조업과 서비스업 부문으로 분류하였다. 연구 결과는, (1) ICT 산업은 수요(Backward Linkage Effect)와 공급(Forward Linkage Effect) 측면에서 자동차 산업의 평균과 비슷한 수준의 파급효과를 가지고 있다. (2) ICT 제조업은 수요와 공급 측면에서 ICT 서비스업의 평균보다 높은 수준의 파급효과를 가지고 있다. (3) 자동차 제조업은 수요와 공급 측면에서 모두 높은 수준의 파급효과를 갖지만, 자동차 서비스업은 공급 측면에서만 높은 수준의 파급효과를 갖는다. (4) ICT 제조업은 수요와 공급 측면에서 모두 높은 수준의 파급효과를 갖지만, 자동차 제조업은 공급 측면에서 높은 수준의 파급효과를 갖는다. (5) ICT 서비스업은 수요 측면에서 높은 수준의 파급효과를 가지고 있었으나 그 효과가 줄어들고 있고, 자동차 서비스업은 공급 측면에서 높은 수준의 파급효과를 갖는다고 보여준다. 이러한 연구 결과를 통하여, 이 전의 연구들에서 논의가 되었던 ICT 산업에 대한 분류 기준을 명확히 제시하였으며 ICT 산업과 자동차 산업에 대한 파급효과 및 중요성을 확인하고, 정책적 시사점을 제시하였다.
