The performance of Enterprise Architecture (EA) in the Korea's public IT domain produces mixed results and responses. On the one hand, EA earns positive remarks and enthusiasm as a central government-wide IT governance framework with its significant IT budget saving records. At the same time, however, the response to EA at the department and agency level is tainted with disappointment, fatigue, and reluctance. This essay suggests that this is perhaps caused by the sterile lackluster concept of EA Business Architecture employed in the current EA practice of the enterprise. The possibility for liberating and reviving the concept of EA Business Architecture is explored. Various conceptual axes and branches of EA Business Architecture are identified based upon extensive EA field experience and observations, and discussions are made on how the concept of EA Business Architecture can be expanded and amplified on those conceptual axes and branched. The resulting EA Business Architecture conceptualization is consolidated into an illustrative typology for EA Business Architecture. In the end the theoretical and practical implications of the research are discussed along with its contribution and limitation.

본 연구에서는 한국에서 도로 승용차로부터 배출되는 $CO_2$, 대기오염물질 및 에너지 소비에 대한 분석, 전망을 하였다. 도로 승용차 교통부분에서의 에너지 소비 및 $CO_2$와 환경오염물질의 추세는 자동차수와 년간주행거리, 평균 탑승자수, 연료 효율을 바탕으로 구하였다. 장래 에너지 소비와 배출, 시나리오 분석은 스톡홀름 환경연구소(SEI-B(Stockholm Environment Institute-Boston))에서 개발한 LEAP(Long Range Energy Alternative Planning System)을 이용하였다. 시나리오는 2005년부터 BaU(Business-as-Usual), CNG(Compressed Natural Gas) 버스의 도입, 경차 이용의 증가, 30$/TC와 300$/TC 탄소세 도입으로 정하였다. 1998년을 기준년도로 하고 2020년을 목표년도로 하여 시뮬레이션하였다. 분석결과 2020년까지의 전망 및 시나리오 분석을 통하여 도로자가용교통부분에서 에너지를 절감하고 $CO_2$ 및 대기오염물질을 저감하기 위하여 도입한 개별정책들을 통합하고 정책간 상승 효과를 볼 수 있도록 팩키지화시키는 것이 효과적이라고 분석되었다.

The purpose of the study is to propose the concrete and realistic alternative measures for $CO_2$ emission reduction on commercial sector. To achieve the purpose, this study adopted AIM/KOREA simulation model modified from AIM(Asia-Pacific Integrated Model) originally developed by Japan National Environmental Research Institute. The results of simulation demonstrate that the $CO_2$ emission from the commercial sector in 1995 was estimated 864 million TC(tons of carbon); however, according to the base scenario, $CO_2$ emission in 2020 is expected to be increased to 1,872 million TC, which is 2.17 times greater than that in 1995. In order to mitigate the ever-increasing $CO_2$ emission, the results of AIM/KOREA simulations under various scenarios showed that the 30-thousand-won carbon tax scenario does not successfully motivate the selection of advanced technology; however, with the 300-thousand-won carbon tax, a substantial amount of $CO_2$ emission reduction by 1.69 million TC from the BaU((Business-as-Usual)scenario is expected to be achieved by year 2020. Such substantial reduction of $CO_2$ emission under the 300-thoudsand-won carbon tax scenario is due to the introduction of advanced technology, such as use of condensing boilers, forced by heavier carbon tax. Under the scenario that presumes the maximum introduction of gas-burning industrial appliances, an 2.66 million TC of $CO_2$ reduction was expected. The results of this study suggest that the $CO_2$ emission reduction measures can be interpreted in many different views. However, if people and industries are fully aware of the economic benefit of energy saving, a certain level of $CO_2$ reduction by a successful introduction of advanced energy saving technology appears to be achieved without carbon tax or subsidies.
