Background: Patient-controlled sedation (PCS) with propofol is a safe and effective method of attenuating discomfort during fiberoptic bronchoscopy. The purpose was to evaluate the usefulness of midazolam in addition to PCS for fiberoptic bronchoscopy. Methods: We randomly assigned 155 patients undergoing diagnostic bronchoscopy to two groups. Group M (n=79) received 0.03 mg/kg of midazolam for premedication while group P (n=76) received a loading dose (0.05 ml/kg) of PCS solution composed of 200 mg (20 ml) of propofol and 1 mg (2 ml) of alfentanil. Both groups received the PCS solution 0.2 ml/kg/hr with a bolus of 1 ml and a lockout time of 1 min. Vital signs, pulmonologist satisfaction, patient satisfaction and amnesia were evaluated. Results: After the insertion of the bronchoscope, there was a slight decrease of SpO2 and an increase of blood pressure and heart rate in both groups with no significant differences between the two groups. The group P required more bolus injections (1.6±1.7 in the group M vs 2.5±2.2 in group P; P<0.05). There was no difference in the satisfaction of pulmonologists, but the satisfaction of patients was higher in the group M (P<0.05). More patients in the group P (93%) remembered the procedure than in the group M (70%) (P<0.05). Conclusions: PCS is an effective method for sedating patients undergoing fiberoptic bronchoscopy and midazolam provides more patient satisfaction and amnesia. (Korean J Anesthesiol 2009;56:1~5)

본 논문은 전기사고 예측을 위해 전기부하의 정상상태와 아크, 누설 상태와 같은 이상상태를 판별하는 새로운 알고리즘을 제시한다. CT를 이용하여 취득된 전기부하의 전류파형으로부터 단순하게 수정된 MFCC와 Shoulder 지속 시간 변화율, 최대치 변화율, 실효치 변화율, 누설전류의 실효치 등을 이용하여 특징벡터를 추출하고, 신경회로망을 이용하여 이상상태와 정상상태를 판별한다. 음성신호처리에 이용되는 MFCC알고리즘을 보다 단순하게 수정한 알고리즘을 전기부하 전류파형에 적용하여 전기부하 이상상태 판별을 위한 특징벡터를 추출하고, 각종 변화율을 계산한다. 신호 처리된 특징벡터는 신경회로망을 이용하여 전기부하의 이상상태 유무를 판별하기 위하여 사용된다. 제안된 단순화 MFCC는 기존의 MFCC 보다 간단한 신호처리 과정을 거치게 되며, 특징벡터 사이즈의 축소가 가능하고 판별 정확도 향상과 함께 처리시간도 단축시킬 수 있다는 장점이 있다. 실험결과는 제안된 방법이 전기부하 이상상태 판별에 유용하게 사용될 수 있음을 보여준다. This paper proposes a new method to classify electrical abnormal states such as arc and leakage currents for predicting electrical accidents. Current data of electric loads are obtained from CTs(Current Transformers), and a simplified MFCC(Mel-Frequency Cepstral Coefficients) algorithm and several change rates are used to extract feature vectors for prediction of electrical accidents. Based on the extracted features, neural networks are used to predict electrical accidents of diverse electrical loads. The original MFCC is being frequently used for speech signal processing and recognition. In this paper, MFCC is modified for the improvement of prediction performance of electrical accidents. The proposed SMFCC(simpified MFCC) is simpler than the original MFCC. Thus, the proposed SMFCC has the advantage that reduce the size and the processing time of the extracted feature vectors. The experimental results show the superiority of the proposed method for predicting electrical accidents.

The purpose of this paper was to study the issues related to converting the graveyards within forests into spaces intended for tree burials by means of planting, given the situation that the graveyards have encroached on land and damaged the environment. For the reason, a field survey was performed to determine the width, length, and distance to the nearest tree of 205 graveyards in the capital area. Through this, it was determined that the domestic lands damaged by graveyards amounted to $862km^2$, including the areas that were deforested to manage the graves. This only confirms that land encroachment by graveyards is a serious issue. The methods for making tree burial sites were examined from the perspective of how to meet public demands given the graveyard's spatial distinctiveness. As a result, this study suggested different methods to establish tree burial sites according to the degree of transformation and the term of its formation. This study also classified the graveyards into three types, and identified the planting methods that harmonized the safe growth of trees and the scenic beauty of memorial places based on the standard. This is in order to plant trees that are shade-tolerant and suitable to the forest line, along with which other tree line was and also, to plant aesthetic trees around the empty space. Through applying the developed methods, this study established and monitored two exemplary sites in Yongin and Boryeng. Aesthetic trees were planted in Yongin site which was located in an open area, aod the shade-tolerant trees were planted in Boryeong, which was located in a forest area. As a result, the image of a garden appeared at Yongin site and the image of a tree colony harmonized with the near forest emerged at Boryeong site. Therefore, it is confirmed that the method of planting according to the distribution status of neighboring trees was effective. As a result of monitoring, mulching wood chips were suitable for sites that were small or easy to approach. This is because the weeds were controlled in Yongin site by mulching. Furthermore, by monitoring the growth of 11 species of vegetation, this study confirmed that low and cover-type vegetations were suitable for tree burial sites. In Boryeong site, the wild cherry trees, which were planted as adult trees, all died, and the tilling of snake's beard, which were planted as cover vegetation, was slow. Therefore, this study found that seedlings were more suitable to plant in forest graveyards than adult trees, which were large and difficult to approach, and it was effective to use the remaining lawn and form a low vegetation after the crown of trees had expanded to such places. 본 논문은 묘지로 인한 국토잠식과 환경훼손이 심각한 상황에서 산지묘지에 수목을 식재하여 수목장지로 전환하는 것과 관련한 제반 사항을 고찰하는 것을 목적으로 한다. 이를 위하여 우선 묘지 훼손지 면적을 파악하기 위하여 수도권 9개 지역 205기의 묘지를 답사하여 묘지의 평균 가로, 세로 길이와 인접수목과의 거리를 측정하여 묘지 관리를 위해, 수목을 제거한 면적을 포함한 전국의 묘지 훼손지 면적이 약 $862km^2$에 달해 묘지로 인한 국토 훼손 문제가 심각함을 확인하였다. 수목장지 조성방법은 국민수요 요인을 묘지 공간의 특수성에서 어떻게 충족시킬 것인가를 관점으로 고찰하여 전환 정도, 조성 기간에 따른 조성기법을 제시하고, 인접수목 분포에 따라 묘지 유형을 세 가지 유형으로 분류하고, 인접 수목이 있는 면은 내음성 산림수종을 식재하고, 인접수목이 없는 면은 경관성 위주의 수종을 식재하는 기준을 적용하여 수목의 안정적 생장과 추모지 경관을 조화하는 식재기법을 제시하였다. 개발된 조성방법을 적용하여 용인과 보령에 2개소의 시범지를 조성하였다. 개활지에 위치한 용인 수목장지는 경관성 위주로 수종을 식재하였고, 숲 내부에 있는 보령 수목장지는 내음성 산림수종을 식재하여 용인 수목장지는 정원과 같은 이미지를 보이고, 보령 수목장지는 숲과 조화된 수목군의 이미지를 보여 인접수목의 분포에 따른 식재기법이 효과적으로 적용됨을 확인하였다. 시범지에 대한 모니터링에서는 용인 수목장지에서 목재칩 멀칭에 의해 잡초류가 효과적으로 억제되는 모습을 보여, 접근이 용이하고 면적이 작은 묘지는 멀칭을 통해 효과적으로 잡초 관리를 할 수 있는 것으로 나타났고, 식재된 11개 초종의 생장과정을 통해 키가 낮고 토양피복도가 높은 종이 수목장지의 지표경관에 적합한 것으로 나타났다. 보령 수목장지에서는 성목 식재한 산벚나무가 모두 고사하고, 지피식생으로 식재한 맥문동의 분얼도 활발하지 못하여 접근이 어렵고, 면적이 넓은 산지묘지는 성목식재보다는 유묘식재를 하고, 잔디를 존치하고 수관이 확장한 후에 내음성 지피식생을 조성하는 것이 효과적인 것으로 파악되었다.

The purpose of this study was to examine the learning capability of the elementary student with SLI. To be more specific, the main topics are as follows. The difference in learning capability (reading, writing, basic mathematics ability) between the student group with SLI and the general student group of the samechronological age as the former. The subject matters are the children with SLI and the general children of elementary school students in 42 lower grades (1st, 2nd and 3rd grade) and in 14 higher grades (4th, 5th and 6th grade). The research test tools of intelligence, learning capability prove the subject matters to be the student with SLI by pediatric psychiatrist or certified speech therapist, and the general children without the experience of speech disorder and share the same intelligence quotient, gender, and chronological age by t-verification with the former group. The data were collected by individual testing and done in statistics by PROC TTEST of SAS program. Above all, independent t- test was executed for the group sorting, between the general student group and the student group who with SLI. After the test, Two-way ANOVA was executed between the two groups for the difference in the studies ability. Results of this study were as follows: A significant difference existed, as regards to learning capability (reading ability, writing ability, and basic mathematics ability), between the students with SLI and the general students whose chronological age are of the same as the former. In conclusion, the result of study shows that poorer performance of the elementary student with SLI on the learning capability test reflect their poor learning capability.
