In this paper, an auto-diagnosis method of the stator winding fault for small induction motor is suggested. 3-phase stator currents are sampled, filtered, and transformed with Park's vector transformation. After then Park's vector patterns are obtained. To detect the stator winding fault automatically, a distortion ratio is newly defined and compared with the one of healthy motor, and the threshold levels of distortion ratio are suggested. The 2-turn, 4-tum, 8-turn winding fault are tested with no load, 25%, 50%, 75%, and 100% rated load. The distortion ratio of the Park's vector patterns are increased as the increase of the faulted turns. but are same as the increase of the load.

The diagnosis technique of stator winding faults based on Motor Current Signature Analysis(MCSA) was suggested. Park"s vector pattern, the circle that is drawn by d-q transformed currents(i_d, i_q), is widely used for stator winding faults detection. The current Distortion Ratio(DR), defined by the ratio of max?axis and min?axis of ellipse of Park"s vector"s pattern, was more simple and powerful method than the Park’s vector pattern. In this study, a calculation method of distortion ratio of Park"s vector pattern was suggested for auto diagnosis of stator winding short fault and usefulness of suggested calculation method of distortion ratio was verified through simulation using LabVIEW program.

This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

박철영,김영설,이현철,장학철 대한당뇨병학회 2001 임상당뇨병 Vol.2 No.4

연구배경 : 제2형 당뇨병 환자의 치료에 새로운 약제인 repaglinide와 기존에 상용하던 gliclazide를 비교하여 repaglinide의 유효성 및 안정성을 비교 평가 하고자 하였다. 방법 : 154명의 환자를 1:1 비율로 repaglinide와 gliclazide군으로 무작위 배정하였다. 약제 투여 전에 탈락된 2명을 제외한 152명의 환자 중 127명의 환자가 투약을 마쳤다. 투약 방법은 2주간의 약제 중지 기간 후에 4주동안 약제 용량 결정 기간을 통해 결정된 용량을 8주간 지속적으로 투여 하였다. 약제 용량은 repaglinide는 0.5mg, 1mg 또는 2mg 1정을 매 주식사 전에 경구 투여하였으며, gliclazide는 80mg 1정 또는 1/2정으로 시작해 제품 설명서에 따라 투여하였다. 치료 전 후의 당화혈색소, 공복혈당, 식후혈당 및 지질대사 지표 등의 검사로 유효성을, 여러 가지 생화학적,혈액학적 검사 및 저혈당빈도 등으로 안정성을 각각 평가하였다. 결과 : 12주 투여 후 repaglinide군과 gliclazide군 모두에서 당화혈색소 및 공복혈당의 유의한 감소를 보였다. 그러나 당화혈색소 및 공복혈당의 감소 정도는 두 군간의 유의한 차이는 없었다. 60분 및 90분의 식후혈당의 변화값의 평균은 repaglinide군에서는 기저치와 비교하여 유의하게 감소하였지만, gliclazide군에서는 유의한 감소를 보이지 않았다. 그러나 두 군의 60분, 90분 및 120분에서의 식후혈당 감소 정도는 두 치료군간에 유의한 차이는 없었다. 총콜레스테롤의 값의 유의한 감소가 gliclazide군에서 있었지만 변화 정도는 두 치료군간의 차이가 없었다. 체중변화는 두 군간 통계학적으로 유의한 차이가 없었다. 두 군모두 우려할 만한 약제 이상반응은 없었다. 저혈당 증상은 gliclazide군이 repaglinide군보다 많았지만 두 군간에 유의한 차이는 없었다. 결론 : 제2형 당뇨병 환자에서 repaglinide는 혈당조절에 대하여 gliclazide와 동등한 유효성을 가지고 있으며 안전한 것으로 사료된다. Background : This study was designed to compare the efficacy and safety of repag linide with gliclazide in a 12-week open-labelled, randomized, parallel group, multi-center study of outpatients with type 2 diabetes. Methods : A total of 182 patients were screened . 154 patients were randomized in a 1:1 ratio of repaglinide (78 patients) and gliclazide (76 patients). Two randomized patients withdrew from the trial prior to receive any trial medication. At the end of trial, 127 patients completed. The study protocol included a screening visit to assess patient eligibility; a washout period of 2 weeks, a titration period of 4 weeks, and a subsequent 8 week maintenance period. Repaglinide was a dministered preprandially with the three main meals, and gliclazide was taken according to the product labeling . Results : After 12 weeks treatment, both repaglinide and gliclazide resulted in significant reductions in HbA_(1c) (p<0.001; both treatment groups) and fasting blood glucose (FBG) values (p<0 .001; both treatment groups). Significant reductions in postprandial blood glucose (PPBG) values were found in the repaglinide group at 60 minutes (p<0.05) and at 90 minutes (p<0.05). However, no significant treatment differences in HbA 1c, FBG, or PPBG were observed. Both number of patients and frequency of reported hypoglycemic events appeared to be lower in the repaglinide group than in the gliclazide group (not significant). Conclusion: Overall, the results showed that repaglinide is well-to lerated and equally effective in controlling HbA_(1c), FBG and PPBG as gliclazide.
