Background: Postburn sternomental contractures cause various changes in mouth, oral cavity, pharynx, larynx and related structures. Although there are many methods to predict difficult intubation, the modified Mallampati test (mMT) and the El-Ganzouri multivariate risk index (EGRI) are popular tests. The authors wanted to compare modified Onah class with these 2 tests and also explored the possibility that Onah class could be an adequate independent predictor for difficult intubation. Methods: One hundred and nine patients, aged 18 to 60 years of age, scheduled for elective surgery for reconstruction of postburn sternomental contractures were divided according to the modified Onah class. We made assessments prior to general anesthesia with respect to mouth opening, thyromental distance, mMT, neck movement, ability to prognath, body weight, and history of difficult tracheal intubation. The accuracy, specificity, positive and negative predictive values were calculated from the data of the 3 tests, and as the 3 tests were compared with patient`s laryngoscopic view grade according to Cormack and Lehane criteria by using the Chi-square test. Results: The incidence of Cormack and Lehane grade III, IV was 39.4%. Onah class showed significantly higher accuracy, specificity, and positive predictive value than mMT and EGRI. There were significant correlations between modified Onah class 2b, 3 and the Cormack and Lehane grade III, IV. Conclusions: Application of modified Onah class for preoperative prediction of the degree of difficulty with laryngeal visualization can reduce the frequency of both an unanticipated failure to visualize laryngeal structures as well as potential unnecessary interventions related to over-prediction of airway difficulty in patients with postburn sternomental contractures.

우리나라는 수자원 특성상 강우의 시간적, 공간적 불균형이 심하여 수자원 개발과 관리여건이 대단히 열악하다. 이에 따라 현시점에서 향후 물 부족에 대처할 신규 수자원의 안정적 확보방안의 하나인 지하댐의 건설 예정지를 파악하고 지표수와지하수를 연계하여 효과적으로 개발·이용 가능한 지하댐 개발의 국내 적용을 검토 할 필요가 있다. 이번 연구는 지하댐 건설 예정지인 경남 하동군 횡천강 일대의 지질조사, 수리·수문학 분석 등을 통해 프로그램 입력 자료를 산정하였다. 또한 입력자료를 바탕으로 SWAT-MODFLOW를 통해 지표수 및 지하수의 연계 해석을 실시하였으며 지하댐 건설전과 후의 지하수위 변화를 예측하였다. Most of hydrological processes of groundwater recharge generally are occupied a rainfall, and recharged an aquifer along infiltrate into subsurface. These processes mainly have an influence by hydrological characteristics and topographic gradient of the aquifer. Development of water resources and its management is not good because of temporal and spatial disproportion in local rainfall. In order to deal with insufficiency of water resources from now on, development of groundwater dam requires a plan of a sustainable of new water resources. These are necessary that investigation of construction area of groundwater dam, effective groundwater development interconnected with surface water and groundwater, and assessment of an application of groundwater dam for utilization of water resources. In this study we were derived the input data by geological survey, hydraulic and hydrological analysis around Hoengchunriver, located in Hadong-gun, Gyeongsangnam Province where is a plan area for construction of groundwater dam. Based on input data we were carried out the interconnected analysis of surface water and groundwater using the SWAT-MODFLOW, and predicted groundwater fluctuation of its construction before and after.

A method for the determination of 16 residual pesticides in crude drugs was examined. Crude drug was extracted with acetonitrile/water solution and the extract was partitioned between hexane/CH2Cl2 and NaCl saturated water. The organic layer was passed through cleanup column and subjected to the GC/ECD or GC/NPD analysis. Essential oil components in crude drug interfere with the analysis, and sulfuric acid treatment was adapted to overcome this interference.
