We surveyed mammalian roadkill at the National Route 6 (Jin-gogae to Songcheon, 18㎞) and a local road 446 (Odaesan National Park office to Sangwon-temple, 12㎞) in Odaesan National Park. Data of the surveys were analyzed by year, month, and species. Roadkills of 226 individuals were found at the survey areas. Of them, the road-killed 131 mammal individuals, 44 bird individuals, 40 reptile individual and 11 amphibian individuals were found during the survey period. High ratio of the road-kills was observed in mammals than the other animals. Among mammalian species, high ratio of the road-kills was observed in squirrels. There were road-kills of three endangered species, containing otters, yellow-throated marten and leopard cats. According to the analyses of annual road-kills, roadkills of 104 cases were occurred and highly frequent in 2014, following by roadkills of 81 cases in 2015, and then those of 41 cases in 2016. Most ases of the roadkills occurred in summer (June to September). The results will contribute to establishing management for reduction of roadkill in Odaesan National Park.

The cardiopulmonary bypass or cerebral circulation arrest is often used in the treatment of complex aneurysm or of arteriovenous malformation to decrease the risk of intraoperative aneurysm rupture. Although experimental studies have suggested that some drugs may protect the brain from ischemic injury, there are limitations in maintaining cerebral perfusion arrest without incurring neurologic deficits due to the initiation of detrimental processes including excitotoxic neuronal injury, activation of phospholipases, influx of calcium, and generation of damaging free radicals. The purpose of this study is to determine wheter mannitol or thiopental has any favorable effects on the recovery of neurologic deficits and on the regional cerebral blood flow(rCBF), somatosensory evoked potential(SEP) and electroencephalogram(EEG) in cats which underwent 15 minutes-complete global ishcemia-reperfusion. The complete global ischemia was produced in 38 cats by temporary intrathoracic occlusion of the innominate artery and the subclavian artery following ligation of bilateral mammary arteries and simultaneous induction of hypotension. The cats were allocated randomly to one of 4 treatment groups : (1) control group, 8 cats received equal volume of saline solution : (2) thiopental group, 10 cats received 45㎎/㎏ thiopental intravenously, (3) mannitol group, 10 cats received 2g/㎏ mannitol intravenously, (4) combined mannitol and thiopental group, 10 cats received equal dose of mannitol and thiopental intravenously. The drugs were administrated in a equally divided dosage before and after the ischemic episode. The results were as follos : 1) Eight animals which received saline showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours after the ischemia. 2) Ten thiopental-treated animals also showed the severe postischemic hypoperfusion and poor recovery of SEP and EEG, and 6 of them died within 6 hours the ischemia. 3) Both mannitol-and combined treated groups showed early recovery of EEG, good recovery of SEP and EEG without the severe postischemic hypoperfusion, and 7 of 10 mannitol-treated animals and 8 of 10 combined treated animals were significantly recovered in all parameters. There were not significant differences in all parameters between the mannitol-and combined treated groups. 4) Thirty-four of 38 animals involved in this 15 minutes-ischemia resulted in the severe neurologic deficits inspite of treatment with mannitol, thiopental or both of them. These results suggest that, in cats, mannitol treatment is effective but not thiopental in preventing severe neurologic injury following complete global ischemia and the duration of complete ischemia should be far less than 15 minutes.

The tempetrature effects were investigated in this research on the substrate removal during the fill period and nitrification during the aeration period for the treatment of the synthetic wastewater by sequencing batch reactor process. The substrate removal rate was ?? during the fill period at 30℃ in the case of the low-loading COD of 508mg/ℓ, and its of the high-loading COD of 1,021mg/ℓwas ??. It was found that the removal efficiency of COD was obtained more than 93% after the aeration period, and also that the substrate removal efficiency was not affected during the aeration period by temperature such as 25℃,30℃,35℃and 40℃ but the ammonia removal was affected by temperature. The specific nitrification rate was ?? at 30℃for the low-loading and its for the high-loading was ?? respectively. After the aeration period, sludge volume indexes(SVI)for the low and high-loading were 113~133 and 68~82, respectively.

돼지감자의 系統別 栽植距離와 主莖切斷時期를 달리하여 生育, 收量 및 糖含量의 變化를 調査하였다. 그 結果를 要約하면 다음과 같다. 白色種보다 赤色種이 株當 塊莖數가 顯著히 많았으며, 塊莖數量도 많았고, 塊莖의 크기도 컸다. 疎植하였을때에 比하여 密植하였을 경우 10a當 地上部와 塊莖收量은 增加하는 傾向이었다. 二系統에 있어서 株當 塊莖種은 草長, 莖直徑, 莖當 節數, 株當 分枝長, 地上部 收量, 株當 塊莖 乾物重과 相關關係가 있었다. 株當 塊莖數는 白色種에서 다른 形質과 有意的인 相關關係는 없었으나 赤色種에서는 다른 形質과 有意的인 相關이 있었다. 主莖切斷時期에 있어서 切斷區에 比해서 無切斷區가 地上部와 塊莖收量이 많았으며, 切斷時期가 이를 수록 약간 增收하는 傾向을 보였다. 白色種이 赤色種보다 糖含量이 높았으며 收穫時期別 糖含量이 變化는 거의 없었다. 貯藏中의 糖含量이 變化는 貯藏期間에 따라 거의 變化 없었으며, 長期間 貯藏이 可能하였다. Field experiment was conducted to determine the effects of spacing in row and main stem cutting date on growth and yield of Jerusalem artichoke. Investigated were also the effects of harvesting date and storage period on sugar content of tuber. The results obtained are as follows; The red line had more tubers per plant and smaller tuber than the white line but the white had more tuber yields than the red line. Top and tuber yield of two lines increased with decreasing spacing in row. Fresh weight of tuber per plant correlated with plant length, diameter of stem, number of nodes per stem, length of branch per plant, fresh and dry weight of top per plant and dry weight of tubers per plant in two lines. Significant correlations between the number of tubers per plant and the other characters were observed in the red lines but were not in the white lines. Top and tuber yield of two lines were decreased by main stem cutting dates and tended to decrease with delaying cutting date of main stems. The white line had a higher sugar content than the red line. Sugar content of two lines was not affected by harvesting date. There was almost no change of sugar content during the storage period indicating that storage of tuber for a long time is possible.

The dyeing wastewater containing biologically recalcitrant and color producing compounds such as dyes and surfactants, is generally considered to be one the most complex wastewater with regard to treatability. At present, the activated sludge process following the chemical coagulation process is being usually used for the treatment of dyeing wastewater. Thus, it is necessary to develop the more simple treatment process to treat refractory organic pollutants color form the effluent. Oxygen activated sludge process with fluidized midia (OASFM) was tested to evaluate design parameters. In this study, the complex dyeing wastewater containing average COD_(Mn) 660 mg/l and BOD 1730 mg/l were treated by the OASFM process which operated at nearly constant MLSS 5000 mg/l. Hydraulic retention time of this process was changed from 12 to 24 hours. The effluent COD of OASFM process was 124-175 mg/l less than 161-225 mg/l of OAS process. In the OASFM process, the optimum conditions were 20 % of media packing rate and 30℃ of temperature. At that condition, the BOD removal efficiency was 99% and COD removal efficiency was 77%.

A successful treatment of infants and children with congenital heart defects depends upon several factors: diagnosis must be accurate, the operative technique, including techniques of perfusion and myocardial preservation, must be suited to the needs of patients and intensive cares, including accurate anesthesia, must be applied through all stages of investigation and treatment, i.e. before, during and after the operation. Recently we performed a open heart surgery successfully for a six-years old girl who had suffered from frequent upper respiratory tract infection and mild to moderate exertional dyspnea with congenital heart defects (ventricular septal defect, Kirklin type II, with patent foramen ovale). The operation and postoperative course were very smooth. And now we report this with review of literatures.
