Bioenergy is classified to one of the renewable energy resources such as solar, wind, hydro and tidal energies. It should be noted that all the renewable energies contribute to the reduction of greenhouse gases emission. In some cases, energy from wastes was also categorized as a renewable energy in our country even though it has only negligible effect on the emission reduction. In this paper, we tried to identify the bioenergy in order to follow the global indices of the renewable energy. The indices evaluated here were whether a resource is renewable, iogenic, biodegradable, combustible and organic. Biogenic and combustible were selected as the indices to identify the bioenergy. It was also suggested that combustible as an index can be exchangeable to organic.

최근 온실가스 배출량에 대한 국제적 이슈가 지속적으로 대두되어 왔다. 본 연구는 이동 배출원 중에서 도로교통부분에 대한 배출량을 산출하는데 필요한 연료소비량 산정에 관한 통계적인 기법들을 비교한 것이다. 지금까지 연료소비량을 산정하는데 단순히 연료공급량 또는 주행거리에 의한 방법으로 초점을 두어왔다. 그러나 연료공급량을 토대로 산출된 배출량은 다양한 차량 및 연식을 반영하지 못한다. 본 연구는 통계적 관점에서 주행거리와 연비를 조합한 각 차량의 연료소비량 및 모든 차량의 소비한 총연료소비량의 추정에 적용되는 방법들을 나열하고 비교한다. 또한 향후 연구로 제시된 일부 방법들에 대해서 차량 및 연식을 고려한 연료소비량의 추정에 관한 현실적인 적용방법을 제시한다. Recently, estimation of greenhouse gas (GHG) emission has continuously emerged as an important global issue. This study compares various statistical methods for estimation of fuel consumption, which is necessary for calculation of GHG emission in road transportation sector. Existing methods have focused on using merely transportation fuel supply or distance traveled for calculation of fuel consumption. Estimates of GHG emission based on fuel supply, however, cannot reflect various vehicle types or model year. This study suggests and compares, from statistical point of view, several methods,which can be applied to estimate fuel consumption of each vehicle, by combining distance traveled and fuel efficiency (mileage), and total fuel consumption of all vehicles. It also suggests practical measures that can reflect vehicle types and model year to suggested methods for future research.

Hypopharyngeal mass is an uncommon condition in the aerodigestive tract. There were only a few cases have been published in the medical literature. We experienced a case of incidentally detected hypopharyngeal mass during endotracheal intubation. Hy- popharyngeal mass was located at the right posterior pharyngeal wall. The hypopharyngeal mass was small and not obstruct the glottis, and endotracheal intubation was performed successfully. We have also briefly discussed symptoms, diagnosis, and related problems during general anesthesia of hypopharyngeal mass.
