서기 2000년이 되어도 현재 에너지 공급의 대부분을 차지하고 있는 석탄, 석유, 가스등 화석연료는 동력원의 대부분을 차지할 것이다. 그러나 원자력이 새로운 에너지로서 원자력선, 원자력 열차, 원자력 비행기가 등장할 것이고 이어 원자력 우주선도 선보일 것이 확실하다. 또 지열은 난방에, 수력과 풍력 그리고 조수등은 모두 발전에 이용될 것이다.

This paper analyzes how Korea's trade intensity with major ASEAN countries changed from 2000 to 2005. For this purpose, we measured the trade intensity index, the trade complementarity index, and the special country bias index between Korea and ASEAN countries by the trade intensity index model developed by Yamazawa (1970). The OECD trade matrix was used as data. We found that Korea's trade intensity with Indonesia increased from 8.91 in 2000 to 10.88 in 2005 due to a considerable increase in Korea's special country bias with Indonesia from 9.58 in 2000 to 10.75 in 2005. Therefore Korea's special country bias with Indonesia should be enhanced further by increasing capital movements and reducing discriminatory tariffs and other import restrictions between Korea and Indonesia. It was also found that trade intensity between Korea and other ASEAN countries (i.e., Malaysia, Philippines, Singapore, and Thailand) shows a similar pattern of the above trade intensity between Korea and Indonesia except the trade complementarity.

The purpose of this study is to analyze the previous research on geological fieldwork from 2000 to 2020, examine the tasks that have been focused on, and suggest directions and implications for future geological fieldwork research. The data was conducted for the thesis searched on ScienceON and RISS in relation to geological fieldwork and journals listed in the Korean Citation Index(KCI), and the study title was analyzed using the semantic network analysis. For analysis, the data that had been pre-processed was visualized as a network by semantic network analysis, and frequency and centrality were analyzed. The centrality analysis was based on degree centrality and eigenvector centrality, and all analyzes were performed by dividing the entire study period into four periods: 2000-2005, 2006-2010, 2011-2015, and 2016-2020. As a result, research on geological fieldwork focused more on the development of geological field courses, and in particular, jeju island was actively discussed as a learning site. Also, the study was conducted on students rather than teachers, and among them, high school students showed high frequency and centrality. In addition, it can be seen that studies on the educational effect of geological fieldwork were discussed, either in connection with programs such as STEAM, free-semester program, or indirect geological fieldwork methods such as web, flash panorama, and 3D. This study is meaningful in that it suggests the direction of future research by looking back on the research on geological fieldwork that has been done so far.

The purpose of this study is to experiment and simulate the newly-updated Second Generation Model for Korea (SGM-Korea). With the updated model, we tried to simulate effect of carbon tax on $CO_2$ emissions and other macroeconomic variables for Korea. The baseline data are compared with projected profiles by various scenarios to evaluate its performance. Our contribution in this study is to having up-graded the model from its earlier version by building new hybrid input-output table based on 2000 input-output and energy balanced tables. According to our estimation, total $CO_2$ emission in Korea has already increased in 2000 to about 1.86 times the 1990 figure. The level of carbon tax required for the current level of $CO_2$ emission to be reduced to the 1995 or 2000 level seems to be too high for Korean economy to bear. It is possible to find a reasonable level of carbon tax, however, if it can combine it with improvement of energy efficiency at the rate of 0.5% to 1% per year. For Korea to meet its obligation to reduce $CO_2$ emissions, therefore, it is imperative for her to improve energy efficiency as well as to develop alternative energy source reducing its dependence on fossil fuel.

This study calculated the three indices of Korea's resource productivity (and raw material productivity), material circulation rate and decoupling factor to evaluate the sustainability of domestic economic activities and resource consumption and examine the extent of dematerialization. Korea's resource productivity improved 22% from 1.32 million KRW/ton in 2000 to 1.61 million KRW/ton in 2007, with the annual average growth of resource productivity during the period standing at 2.88%. Raw material inputs accounted for 73-76% of domestic material consumption (DMC); raw material productivity for the year 2007 was 2.11 million KRW/ton, growing 3% on annual average from 2000 through 2007. The wastes released are circulated into the economic system through recycling and energization. Korea's material circulation went up from 10.9% in 2000 to 15.6% in 2007, growing by an annual average of 5.3% during the period. The rate of change in year-on-year growth, however, was found to be on the gradual decrease. This study also showed that Korea's economic activities were decoupled with its resource consumption as the country heads toward dematerialization through sustainable resource management.
