Greenhouse gas (GHG) emissions have given rise to climate change which is one of the most serious environmental challenges that the world faces today. In response, Republic of Korea has proposed "Low Carbon, Green Growth" as a new economic paradigm accompanying with the ultimate aim of building a sense of responsibility for the environment. Korean government has set the ambitious national GHG emission reduction target which aims 37% reduction in the business-as-usual (BAU) level of 2030. The transportation sector plays a key role in this target. In the transportation sector, the GHG reduction target of 34.3% in the BAU level by 2020 has been allocated in order to consider the industrial specificity. Furthermore, it is known that the GHG reduction in the transportation sector has relatively minimal side effects compared to those of other sectors. In order to meet this national GHG reduction target, Korean government has set $CO_2$ emission regulation of vehicle for 2020. The purpose of this study is to evaluate the reduction effects by the average GHG regulation of vehicles. $CO_2$ emissions, between 2009 and 2013 were analysed by reduction measure such as technology improvement, light-weight, segment shift, diesel vehicle sales. During this period, $CO_2$ of vehicle was reduced every year by 19.9 g/km (i.e., 3.3% reduction per year). $CO_2$ reduction of imported vehicle is greater than domestic vehicle because of segment shift toward small size vehicle and higher diesel vehicle sales.

코로나 19가 국내에서 2020년 1월 첫 확진자가 발생하며 현재까지 pandemic 상황이 지속하고 있다. 전례 없는 상황에 코로나 19는 교통 분야에도 영향을 끼쳤으며 시민들의 생활패턴변화로 교통량의 변화 및 대중교통 이용변화에 적절한 대응 방안이 존재하지 않았다. 현재 각 지자체에서는 pandemic 상황에 대한 질병 대책 방안은 별도로 수립하고 있지 않다. 향후 교통분야 질병 대책 방안 수립을 위해 교통량 및 대중교통 이용 건수를 분석하였으며 예측모형 개발을 위해 코로나 19 현황과 상관도 분석을 수행하였다. 분석 결과 교통량은 감소하였지만 개인 교통수단의 증가로 교통량 감소량은 대중교통 이용 건수에 비해 감소율이 낮다. 또한 대중교통 이용 현황은 초기에는 확진자 수에 영향을 받았지만 시간이 지남에 따라 확진자 수 보다는 사망자 수와 치명률에 더욱 민감하게 반응하는 것으로 분석되었다.

국가 온실가스를 산정, 보고, 검정을 관장하는 온실가스종합정보센터가 2010년에 출범된 후, 주요 업무의 집합체인 국가 온실가스 인벤토리 보고서가 2012년부터 해마다 발간되었다. 보고서에는 부문별 온실가스 배출량 및 불확도가 보고되고 있지만, 대부분의 부문에서 불확도의 기입은 단순히 IPCC 가이드라인의 기본값으로 대체되고 있는 실정이다. IPCC 가이드라인은 부문별 온실가스 배출량을 산정함에 있어 Tier 수준에 따른 구체적인 산정식을 제시하고 있지만, 불확도의 경우 확률밀도함수 추정 또는 몬테카를로 방법 등을 적용한 국가고유 방법론의 개발을 권고하고 있다. 도로교통부문도 배출량이 Tier 1수준으로 산정되고 있지만 불확도는 보고되지 못하고 있는 실정이다. 본 연구는 도로교통부문에서 일반자가용자동차대형을 대상으로 활동자료인 연간 주행거리, 연비 그리고 배출계수를 이용하여 연간 배출량을 산정하는데 국한하지 않고 불확도 산정에 적용되는 여러 통계적 기법 중에 한 가지인 붓스트랩 및 몬테카를로 방법을 소개하는데 있다.

도로물류부문의 온실가스 저감 및 물류체계를 효율화하기 위해서는 화물차의 운행효율화가 무엇보다 중요하다. 효율적인 수송체계의 구축은 화물차의 적재효율 향상, 수송수단의 전환 등을 통하여 온실가스 저감 및 수송비용을 절감할 수 있다. 또한, 물류부문의 환경부하량을 감축하기 위해서는 환경부하를 정량적으로 파악할 수 있어야 한다. 하지만, 국내 물류기업의 환경부하에 대한 체계적인 조사가 미비한 실정이다. 본 연구에서는 국내 물류부문의 화물환경지표로 화물수송실적(ton km) 당 $CO_2$ 배출량으로 설정하였다. 여기서, 화물수송실적(ton km) 당 $CO_2$ 배출량은 1 ton의 화물을 1 km 수송할 때 배출되는 $CO_2$ 양이다. 국내 물류기업을 대상으로 분석한 결과와 영국, 프랑스의 화물수송실적 당 CO2 배출량을 비교하면 국내 업체가 $363g-CO_2/ton{\cdot}km$로 영국 $130g-CO_2/ton{\cdot}km$에 비해 2.8배, 프랑스 $97g-CO_2/ton{\cdot}km$로 3.7배 높게 배출되는 것으로 나타났다. 이는 영국과 프랑스에 비해 국내 화물차의 공차 운행율이 높고, 적재 효율은 낮은 것이 주요 원인으로 판단된다.

Due to the development of information technology, Convergence and Creative Economy became hot issues. For example, products become more intelligent and services are likely to be connected and integrated around core services or provided as bundle solution. Meanwhile products and services are integrated in the context of mutual supplementation, which leads to Servitization of Products and Productization of Services in many industries. Previous studies have addressed Convergence with different terms and definitions such as Convergent, Multicategory Multifunctional Product, Clouding Service, Bundle and so on from one perspective such as consumers, suppliers or technology according to a wide range of academic approaches. Thus, this study attempted to suggest the most typical convergence products released in the convergence environment and categorize those products. Furthermore, this study has pointed out the problems in the New Product Development Framework discussed in the studies on marketing by taking the situation of the public sector into account and then suggested "New Service Development Framework in the Public Sector" that are different from traditional e-Gov. approach basically and will enable the government to create public information service and provide them to enterprises or citizens. It also emphasized the importance of Business Conceptualization Stage in the framework; argued that there is a necessity of an integrative study from the perspective of technology on the basis of the approach from the perspective of marketing and Policy such as a study of consumer behaviors, design and marketing channel and Policy Integration for the development and dissipation; and furthermore suggested the cases-the development/Diffusion of Transportation Card Service in Seoul and CFC (Call for Collaboration) in Singapore-in order to verify the framework. There is a need to supplement New Service Development Framework so it is able to reflect the distinct characteristics of the public sector from the academic perspective and be used as practical guidelines for SI (System Integration) business to shift into IT Service business. Last but not the least, this study has suggested the limitations and the directions for the future studies.

The purpose of this study is to investigate the economic potential of the regions from the mining sector of North Morowali, Central-Sulawesi, Indonesia, and the formulation of pro-business regional development management that aims to create synergy between the local government and mining sector entrepreneurs. This study uses a descriptive qualitative approach by taking data in the form of primary data from FGD and secondary data observations from statistical bureau data in the North Morowali, Indonesia. The analysis unit uses SWOT analysis to determine the economic potential of the North Morowali and Location Quotient (LQ) to analyze the economic potential of the mining sector. The research period covers one year (2018-2019) in North Morowali, Indonesia. All the mining products have considerable potential as a financing unit in North Morowali, while mining potential has not been maximally exploited. The absence of regulations, facilities such as road access, and optimal land and sea transportation are the causes of the difficulty of optimization and access to explore mining products comprehensively. As a new province at Central Sulawesi, more efforts and the role of government are needed to focus attention to North Morowali as an area with great potential in the mining sector.

The current transportation regime is largely based on two alternatives: (1) fixed route public transit, and (2) private ownership of internal combustion engine (ICE) powered vehicles per households. This paper analyzes one possible transportation alternative, Micro Electric Vehicles or MEVs, and compares with the ICE vehicles in terms of social, economic and environmental benefits, especially emphasizing its environmental advantage over ICE vehicles for future sustainability. While some representative models of MEVs exist in a limited market capacity, but global technical standards are generally insufficient and non-homogenous across nations, which restricts the development of the proposed transportation sector. The focus of this paper is to analyze the characteristics and potential benefits of MEVs in economical and environmental perspectives, including development status and technical standards, with a particular focus in the E.U., the U.S., Japan, and Korea. Based on the data of analysis, this paper aims to derive and propose a cooperative and adaptive global policy framework designed to speed up adoption and expansion of the global MEV market, including passenger and utility vehicles. We propose MEV to be a new mobility segment in the global transportation market because of their advantage in environmental impact, sustainability, overall cost of ownership, and safety.

This paper introduces an approach to identify the total energy consumption with subsequent $CO_2$ emissions, for both industrial and non-industrial sectors. Statistical data for 2005 were compiled in a national account system to construct an energy input-output table for investigating the influence between energy demand and supply activities. The methodological approach was applied to South Korea. Twelve types of energy and fifteen industrial and non-industrial sectors are formed as the compartments of the input-output table. The results provided quantitative details of the energy consumption and identified the significant contributions from each sector. An impact analysis on the $CO_2$ emissions for the demand side was also conducted for comparison with the supply side.

It is expected that transportation sector will develope to a systematic and multi-disciplinary way in which transportation, information and electronic technologies are harmonized. This will be the way that the 21st century demand. To be prepared for such development, sharing of information from different sources through a integrated approach is essential. Also an active role of specialized staff are required to achieve a integrated control and management. The specialized staff should do his best for his task with appropriate specialty, a sense of responsibility, a progressive mind and a vision. He also make much effort to enhance and keep up-to-date his specialty. Then we can modestly look forward to a specialized Information society in the 21s1 century.
