기후변화에 관한 정부 간 패널기구(IPCC)는 온실가스 배출통계 작성과 관련한 국제적 기준을 정한 보고서에 따라 온실가스 배출통계의 정밀도 및 난이도를 고려하여 Tier 1/2/3의 세 가지의 방법론을 제시하였다. 국내의 경우 기존의 인벤토리 구축은 우리나라 전체 에너지소비량을 교통수단별 배출계수를 적용하여 산출하는 Top-down 방식으로 이루어 졌었고, 배출계수는 승용차의 계속적인 증가와 도로 구간 변화가 반영되지 못한 국내 교통상황에서 진행되었다. 온실가스 배출량 산정에 있어 $CO_2$의 배출량은 연료에 따른 탄소 함량으로 산정 하는 것이 보다 정확한 배출량 산정을 할 수 있다고 IPCC에서 제시함에 따라 정확한 배출량 산정을 위해 수송용 연료에 대하여 국가 고유 탄소 함량을 월별 또는 계절별 분석을 통하여, 국가 온실가스 통계의 정확도 제고와 최신 배출통계를 통해 앞선 기후변화 대응 대책 수립을 가능하게 할 것이다. Intergovernmental Panel on Climate Change(IPCC) suggested the three methodology, Tier 1/2/3, considering with the accuracy and difficulty of greenhouse gas emission statistics according to the report determined as the international criterion. In Korea, the existing inventory building was made by the Top-down approach applying with the emission factors for transportation in the entire energy consumption, the emission factors were investigated under the domestic traffic situation which did not reflect by the continuing increase of vehicle and the change of road section. From the suggestion of IPCC, which it is estimated that the emission estimation of $CO_2$ in greenhouse gas emission could be calculated more accurate by the carbon content according to the fuel, the establishment of measures to respond to climate change from the latest greenhouse gas emissions statistics will be able to improve the accuracy of national statistics using monthly or seasonally the analysis of carbon content about the transportation fuels.

Purpose: We investigated to identify the effect of robo-horseback riding exercise (RHRE) on trunk muscle activity ratios for patients with low back pain. Methods: Twelve patients with low back pain and twelve healthy adults were recruited for this study. Subjects performed the RHRE with the neutral spine position. The amplitude of electromyography activity was recorded from the selected trunk muscles (internal oblique [IO], rectus abdominis [RA], multifidus [MF], the thoracic part of the iliocostalis lumborum [ICLT]). The ratios of the relative local muscle activity to the global muscle activity in abdominal and lumbar parts were calculated. Results: There were significant differences in the change values of the IO/RA and the MF/ICLT between low back pain (LBP) patients and healthy adults. The IO/RA ratio and the MF/ICLT ratio showed significant increase in LBP patients after training. Conclusion: The RHRE improved the trunk muscle activity ratio in patients with low back pain. The information presented here is important for investigators who use lumbar stabilization exercises as a rehabilitation exercise.
