This paper aims to quantify the potential economic burdens of EU's carbon border adjustment mechanisms faced by Korean domestic industries. In addition, this study tries to compare and analyzes changes in the burden of each industry resulted from the implementation of the domestic low-carbon policy. Based on the quantitative findings, we intend to suggest policy implications for establishing mid- to long-term strategies in response to climate change risks. Based on the environmentally extended input-output analysis, the total economic burdens of the domestic industries due to the EU's carbon border adjustment mechanisms are estimated to be approximately KRW 8,245.6 billion in 2030. Looking at the impacts by industry, it is found that major industries such as petrochemicals, petroleum refining, transportation equipment, steel, automobiles, and electric/electronic equipment industries are expected to account for 84.3% of the total potential burdens. In addition, in multiple policy scenarios assuming technological developments and energy transition following the implementation of domestic low-carbon policies, the total economic burden of carbon border adjustment is expected to decrease by about 11.7% to 15.0%. The main result of this study suggests that we should not view EU EU's carbon border adjustment mechanism as a trade regulation, but to use it as a momentum for more effective implementation of the low-carbon and energy transition strategies in the global carbon neural era.

The policy aimed at introducing a Bonus-Malus system to reduce GHG and raise the market share of small cars is scheduled to go into effect in South Korea in 2020. Although the policy was originally planned to be enforced from 2015, the Ministry of Trade, Industry and Energy argued that the system brings low reduction effect and relative disadvantage to domestic small cars and brought arguments in 2014. As a result, the enforcement was pushed back. Related studies are mainly focused on offering statistical estimation of the policy's effect to support the arguments, and few theoretical studies were published given that there was not enough time until 2015 back then. The author approached the issue with mathematical modeling in order to give theoretical basis for sophisticated empirical studies. If car suppliers have market power and strategically set their prices, the impact of Bouns-Malus on car prices would be lower than what was originally intended. In case only a part of the car market loses its market power, the effect of the policy would be improved. Assume that the Bonus-Malus is currently at an optimal level and the car market structure is undergoing changes, then the direction of the new optimal level would depend on the elasticity of demand of each market and substitute elasticity. For example, if the car market becomes more monopolistic while the demand for big cars is elastic, demand for small cars is inelastic and substitution elasticity is low, then the new optimal level of Bonus-Malus should be higher.

DRM(Distal Right Management)은 컨텐츠의 불법 사용을 방지하여 저작권을 보호하고, 컨턴츠의 생성·유통·사용 관리 등에 필요한 모든 처리를 지원하는 종합 솔루션이다. DRM 체계에서 사용자(customer)는 컨텐츠를 정당하게 사용하기 위해서 클리어링하우스(clrearinghouse)로부터 라이센스를 발급받아야 한다. 일반적으로 라이센스(license)는 사용자의 공개키로 암호화된다. 그래서 사용자의 계산적 부담이 크다. 특히 무선 DRM 환경이라면, 사용자의 부담은 더 클 것이다. 따라서 본 논문은 익명성을 갖는 제안 1회용 대리서명 기법과 Y.Zheng의 Singcryption 기법을 적용하여 사용자의 계산량을 줄이고, 익명성을 갖는 효율적인 라이센스 다운로드 방식을 제안한다.

1970년도 후반까지만 하더라도 염료생산은 선진국형 산업으로만 생각하여 왔으나 인건비 상승, 환경처리비부담, 운성비 등의 부담으로 선직국의 염료생산공장들은 앞다투어 생산기지를 후진국으로 신설 또는 이전을 하게 되었다. 한편 생산량도 증가되어 수요에 비하여 공급과다로 지나친 판매경쟁이 일어나고 채산성도 나빠진 것이 현실이다. 이러한 나라들 중에는 제조기술의 미흡, 원가절감, 품질관리의 미숙 등으로 lot별 농도차이, 용해성불량, 염료중에서의 재응집, 飛散등의 문제로 염색공장에서 애로를 겪는 경우가 자주 발생하고 있다. 특히 염료의 비산 문제는 칭량원의 보건상 나쁜 영향을 미치게 되고 염색현장까지 염료입자가 날아가 피염물에 오염을 일으키기도 한다. 이러한 문제점을 해결하기 위하여서는 다각적으로 관리에 철저를 기하지 않으면 안된다.
