최근 국내에 MSW(Municipal Solid Waste), RDF(Refuse-Derived Fuel) 또는 석탄과 폐기물을 혼합 연소하는 Waste-To-Energy 보일러 대한 관심이 증대되고 있는바, EPRI(Electric Power Research Institute)의 연구자료를 인용하여 상기 보일러에 대한 튜브 손상 메카니즘에 대하여 설명하고자 한다.

Introduction: It is frequently occur in sports injury of clavicular fractures in Hapkido players. Weevaluated Hapkido related clavicular fractures and preventive measure. Methods: We experienced 12 cases of Hapkido related clavicle fracture. The age ranged from 13 to18-years-old. All cases were treated by conservative managements. We examined the relationship between the clavicle fractures and Hapkido related pathomechanics.Results: All cases were injured during the practice for the falling-technique. Results were evaluatedby Weitzman and all cases were revealed more than good. Conclusions: In most cases, the correction of the wrong way of falling-technique will reduce theclavicle fractures in the Hapkido players.

A nonlinear cumulative damage theory, which can model the effects of the magnitude and sequence of variable amplitude fatigue loadings, is proposed. The concrete beam specimens are prepared and tested in four-point flexural loading conditions. The variable-amplitude fatigue loadings in two and three stages are considered. The present experimental study indicates that the fatigue failure of concrete is greatly influenced by the magnitude and sequence of applied, variable-amplitude fatigue loadings. It is seen that the linear damage theory proposed by Palmgren and Miner is not directly applicable to the concrete under such loading cases. The sum of the cumulative damage is found to be greater than 1 when the magnitude of fatigue loading is gradually increased and less than 1 when the magnitude of fatigue loading is gradually decreased. The proposed nonlinear damage theory, which includes the effects of the magnitude and sequence of applied fatigue loadings, allows more realistic fatigue analysis of concrete structures.
