  • The Life Cycle Assessment (LCA) as an environmental impact assessment tool has received increasing attention over the years. Unlike the water footprint (WF) and carbon footprint (CF) assessments whose focus is only on a single environmental aspect, the LCA systematically analyzes the different impacts along the entire life cycle, making possible the identification of potential environmental tradeoffs. In Korea, LCA has drawn much attention from both industry and academia since the mid-90s. However, the level of Korea-related LCA studies with respect to different sectors in the past 20 years has not been analyzed. This study, therefore, sought to assess the status of environmental Life Cycle Assessment (LCA) studies in Korea, with a view to understanding the current level of sustainability reporting and identify potential research gaps. Online searches of English written articles published between 2000 and 2019 were conducted on Google, Google scholar, Scopus, and Web of Science databases using the Keywords "life cycle assessment", "lca", and "Korea." At the end of the search, about 88 LCA related studies were identified for Korea within the study period. Majority of these studies focused on the construction (49%) and energy (31%) sectors with fewer environmental studies on the transportation (9%), manufacturing (8%), agriculture (2%), and information and communication (1%) industries. Based on publication trend, results show that LCA studies in Korea have been on the rise in the past 20 years, even though the number of publications has not followed a constant pace. In comparison with the economic sectors of the country, reports show an inadequacy in the coverage of major industries of growing economic relevance like the tourism, health, and agriculture, suggesting a need to further increase and improve LCA related studies in these sectors.

  • After industrialization in the past, the automobile industry has continued to grow centered on internal combustion engines, but is facing a major change with the recent 4th industrial revolution. Most companies are preparing for the transition to electric vehicles and autonomous driving. Therefore, in this study, topic modeling was performed based on LDA algorithm by collecting 4,002 domestic papers and 68,372 overseas papers that contain keywords related to CASE (Connectivity, Autonomous, Sharing, Electrification), which represent future automobile trends. As a result of the analysis, it was found that domestic research mainly focuses on macroscopic aspects such as traffic infrastructure, urban traffic efficiency, and traffic policy. Through this, the government's technical support for MaaS (Mobility-as-a-Service) is required in the domestic shared car sector, and the need for data opening by means of transportation was presented. It is judged that these analysis results can be used as basic data for the future automobile industry.

  • The Imwon Sipyukji of this study was compiled by Seo Yugu (1764~1845), a famous agronomical scholar of the late eighteenth century. The contents of this book are divided into sixteen chapters related to all the important parts of rural home life ranging from daily routines to social life covering the agro-industry and the six skills of manners, music, archery, calligraphy, mathematics and horseback riding. Seomyongji, one of the sixteen chapters, covers all that is necessary for living a rural existence such as house-building, clothing adornments and transportation as well as how to make and use daily household items. The contents of the Boksik Jigu sub-section in the Sumyongji chapter consist of eight large units covering men's and women's clothing, bedding and pillows, sewing tools, belt and shoes accompanying the attire and storage for clothes. These eight are further subdivided into 65 items, each warranting a detailed explanation. My study will translate the original Chinese text of Boksik Jigu into Korean. This sub-section in the Seomyongji chapter will facilitate an investigation into the information contained therein on attire and accessories.

  • Kimpo International Airport, located within the Seoul metropolitan district, experienced a sudden surge of passengers and cargo in recent years. In 1990, MOCT sponsored feasibility studios and Youngjong Island location was selected as the most suitable choice among four proposed sites to build a new airport. The construction work was then commenced in November 1992. Phase I project facilities are scheduled to start its operation in March 2001 with an annual capacity of 27 million passengers and 1.7 million tons of cargo for both enplaning and deplaning from International liners. Kimpo International Airport will remain in operation primarily for domestic passengers and cargo only. Phase II project construction work will add two more runways with its related facilities by 2005. Inchon International Airport will then conveniently serve 100 million passengers for enplaning and deplaning, and 7 million tons of inbound and outbound cargo annually in its full capacity. All the airport facilities In phase I and phase II periods are constructed to meet international standards. A fully integrated transportation network and logistics function systems should be accomplished prior to the full operation of the airport. With these sccomplishments, the state-of-the-art airport is poised to meet the needs of a rapidly growing worldwide air transport industry, and will more than adequately fulfill its role as a hub airport for the Northeast Asia region.

  • Carbon Capture and Storage (CCS) technologies involve three major stages, i.e., capture, transport, and storage. The transportation stage of CCS technologies has received relatively little attention because the requirements for $CO_2$ transport differ based on the industry-related conditions, geological, and demographical characteristics of each country. In this study, we analyzed the properties of $CO_2$ transport using a pipeline. This study has important implications for ensuring the stability of a long-term CCS as well as the large cost savings, as compared to the small cost ratio as a percentage of the entire CCS system. The state of $CO_2$, network topologies, and node distribution are among the major factors that influence $CO_2$ transport via pipelines. For the analysis of the properties of $CO_2$ transport using a pipeline, the $CO_2$ pipeline connections were visualized by the simulator developed by Lee [11] based on the network topologies in $CO_2$ transport. The case of Korean CCS technologies was applied to the simulation.

  • The standard of agricultural mechanization is one of the important indicators for measuring the realized degrees of agricultural modernization in some regions. The Pearl river delta is most fertile, and thereby reputed as a land of fish and rice in the province. Studying the proceedings, profits and experiences of agricultural mechanization in the region obviously possesses the generally guiding significance for Guangdong to realize agricultural modernization by the year 2010. this paper involves these fields such as duainage, irrigation, harrowing, harvesting, transportation, processing and etc, in the Pearl River Delta, Results show as follows: (1) 80% work load in main production links has been mechanized ; (2) changed took place in traditionally agricultural production means and ways so took place in traditional agricultural production means and ways so that individual farmer in this region became commercial producer and then march toward commodity production of moderniza ion with high yields, good guality and high profits ; (3) further taping production potential to improve land output and labour productivity. Results also show that the degrees of agricultural mechanization in the Pearl River Delta are closely related to government' spolices, finance, moderate land scale management, rural industrialization and machine utility as well as talent training, shortage of which will surely; affect the proceeding of agricultural mechanization. Therefore, government must be urged to guarantee it by preferential policies and financial loan so as to greatly run rural industry, to create conditions for land scale management, to set up the socialized service system of agricultural mechanization, to actively train scientific talents and to introduce advanced equipments and technology from aborad in order to quicken the progress of agricultural mechanization in this regions.

  • Globally, consumers' enormous and increasing appetite for meat is one of the biggest causes of climate change because livestock industry emits more greenhouse gas than transportation. The purpose of this study is to analyze consumer awareness about the impact of meat consumption on sustainability in response to climate change. Based on the theory of planned behavior, the attitudes, subjective norms, perceived behavioral control, prior knowledge, and risk perception variables were analyzed to evaluate the impact of climate change awareness over consumer behavior on meat consumption. Major findings are as follows: consumers were aware of climate change but has made few changes to their meat consumption. In addition, changes in meat consumption were found to be caused by health safety concerns, such as disease outbreaks. Significant variables related to meat consumption patterns associated to climate change impacts were household income, age, attitude, subjective norm, perceived behavioral control, and prior knowledge. These results suggest some implications for policy. There is a need for public relations and education to make the public aware of and better understanding of link between climate change and diet. Also, government should make efforts to raise awareness of mitigation of climate change such as comprehensive food labels which are identifying lesser impacts on climate and better dietary guideline instructions which would include coping with climate change.

  • Korea is an industrial country that overspends energy and has a policy that is more focused on a supply side. When an urban developmental program is to set up, surveys are carried out only with the respect to electricity, telecommunication, gas, and heating sources. Based on the existing survey results, the problems related to the supply side are being dealt with more importantly and the quantities of those supplies are estimated only by each energy source. The aim of this study is to provide basic information on energy consumption patterns of a diverse comsumer groups including industry, transportation, commerce, public and household to plan diverse energy policies. Through this basic information, it may be possible to analyze the energy consumption pattern by each consumer group and provide data for setting up efficient energy policies by the government. The energy consumption map that are analyzed and developed by the data obtained from Busan municipal area will be deposited and used as a part of the national energy statistics.

  • The $1^{st}$ National Plan for Aging Society with Low Fertility, which the Korean government announced in 2006, caused the gradual increase of R&D investment in order to prepare for an aging society in Korea. This study explores if the directions and strategies of R&D projects related to aging are suitable to improve the quality of life for elderly people and establish a sustainable aging society by analyzing the features of R&D investment from 2004 to 2010. The results show that most R&D projects conducted by departments focus on the development of assistive devices for the elderly to support everyday lives. The Korean government's R&D policy to prepare for an aging society is based on the narrow interpretation of Quality of Life (QoL) in an aging society that tries to resolve the socioeconomic problems of the elderly; however, the policies have ignored the independence of active elderly individuals and the social integration of the young and elderly generations. The research shows that a paradigm shift is required from a 'Senior' to 'Aging Society' because almost 1/3 of the Korean population is over 65 years old and the expansion of the research embraces from assistive technologies for the elderly to the design of social infrastructure such as transportation, education and work.
