The fire area need management to prevent enlargement of collapes and sinkage. and it need that repair Vegetation sack work, Soil arresting structure, Terrace-sodding works, Direct seeding works in greening works and Water cushion in erosion control dam. The whole of the Concrete stream grade stabilization structures were broken, it need to be repair. As pass the time, a lot of structures were abandoned. Therefore, it need to reorganize erosion control structures and the method of construction in the fire area

Estimation of the minimum post-mortem interval (PMI-min) by means of forensic entomology is mainly based on the results of the growth rate studies on necrophagous flies. However, results of these studies are difficult to use because these studies have only been undertaken for a select few necrophagous flies, and experimental methods and results processing have not been standardized. In this review, we have summarized the current state of growth rate studies on necrophagous fly species that are frequently found in human cadavers. Criteria have been suggested in order to select reliable data, and the accumulated degree hours and base temperatures to be used in the calculation of PMI-min for each species have been tabulated.

인공 비탈면에 있어서 Geo-textile 소재의 피복자재가 유출수량, 부유물질량, 유출토사 및 식생생육에 미치는 영향을 파악한 결과는 다음과 같다. 1. 식생의 종류조성은 12과 21속 20종 2변종 총 22종류였으며, Geo-textile 소재의 피복자재가 파종종자의 개체수 및 시험구의 피복율을 증가시키는데는 효과적이었지만 비탈면 녹화에는 한계가 있는 것으로 나타났다. 2. 유출수량은 강우량에 비례하여 증가하였고 피복자재구가 미설치구보다 최대 1/15.5배 저감되었다. 3. 부유물질량과 유출토사량은 강우량에 비례하여 증가하였다. 피복자재구가 미설치구보다 각각 최대 1/47, 1/151배로 저감되어 피복자재가 부유사 및 토사의 유출억제에 매우 효과적인 것으로 나타났다. The effects that the geo-textile mulching sheet has influenced on the runoff-water. suspended solid, sediment yield and vegetation growth are as follows in artificial slope. I. The flora of plots was composed 12 families, 21 genera, 20 species, 2 varieties, total 22 taxa. 2 The geo-textile mulching sheet is effective on increasing of introduced vegetation population, number of species and vegetation coverage, but just only with the mulching sheet it shows limit of was somewhat difficult to expect the increase of the existence ratio. 3. The amount of runoff-water increased in proportion to rainfall and a t mulched plots were about 1115.5 as decreased as that of un-mulched plots. 4. The amount of suspended sediment increased in proportion to rainfall and at mulched plats were about 1/47 as decreased as that of un-mulched plots. 5. Also, the amount of sediment yield increased in proportion t o rainfall and at mulched plots were about 1/151 as decreased as that of un-mulched plots. so, multi-function-filter is very effective on prevention of soil erosion.

The objective of this study was to investigate the treatment efficiency, kinetics, and morphological characteristics of biofilm in upflow Biobead process, a kind of biological aerated filter(BAF). The Biobead system showed high removal rates of CODMn(76∼83%), BOD5(67∼88%) and SS(71∼91%) for food wastewater with high salt concentration(>4,000㎎/ℓ) under short reaction times(2∼3hrs). Even at aerobic condition, the system had high treatment efficiency for both T-N(51∼63%) and T-P(62∼81%). The removal kinetics of CODMn, BOD5, T-N, T-P, and Cl- in the Biobead system showed a plug-flow pattern with reaction rate constants(hr-1) of 0.58, 0.63, 0.30, 0.48, and 0.38 respectively. A backwashing process to remove excess biomass and filtered solids was needed at least once during 22-hour operation at 0.5㎏ BOD m-3·d-1 loading. At the higher loading(1.0㎏ BOD m-3·d-1) the backwashing interval was shorten by 8 hours. The COD, BOD, T-N, and T-P were removed from 43 to 66% only by aerobic biodegradation. The SS was removed over 70% by the filtering of Biobead media in the treatment system. The first one of three serial Biobead reactors showed the highest removal values for CODcr(52.3%), CODMn(38.8%), BOD(62.5%), and T-N(40.0%). The SS and T-P had the highest removal values(47.5% and 29.2%) at the second one of the serial reactors. The biofilm had non-homogeneous spatial distribution and the colonies were embedded in the sunk area of the Biobead. The thickness of the biofilm was very thin(5.0∼29.4㎛) compared to the biofilm thickness(200∼300㎛) used in other BAF systems.
