        Park's 벡터 패턴의 왜곡률을 이용한 고정자 권선 고장 자동진단

        宋明現(Myung-Hyun Song),朴奎南(Kyu-Nam Park),韓東奇(Dong-Gi Han),梁哲午(Chul-Oh Yang) 대한전기학회 2008 전기학회논문지 P Vol.57 No.2

        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.

      • LabVIEW를 이용한 유도전동기의 권선고장 자동진단

        한동기(Dong-gi Han),송명현(Myung-hyun Song),박규남(Kyu-nam Park),이태훈(Tae-hun Lee) 대한전기학회 2006 대한전기학회 학술대회 논문집 Vol.2006 No.7

        본 논문에서는 유도전동기의 고정자권선 고장진단을 목적으로 이상적인 전동기의 전류신호와 실시간으로 운전하고 있는 전동기 전류신호를 Park’s Vector에 각각 적용시켜 Park's Vector 패턴을 만들고 패턴 피크값의 기준치와 측정치의 편차를 이용하여 오차치를 벗어날 때 고장으로 진단하는 Park's Vector 패턴의 피크값을 이용한 고정자권선의 고장진단을 시도하였다. 숙달된 작업자가 Park’s Vector패턴을 보고 고장을 분석해야 했던 방법과는 달리 패턴을 비교하지 않고도 자동으로 고장을 진단하고 정보해주는 진단 방법을 제시하였다. 실제 전류분석 및 진단을 위해 상용 프로그램인 LabVIEW를 이용하였다.

        LabVIEW를 이용한 소형 유도전동기의 권선고장 자동진단

        宋明現(Myung-Hyun Song),朴奎南(Kyu-Nam Park),韓東奇(Dong-Gi Han),禹奕在(Hyeok-Jae Woo) 대한전기학회 2006 전기학회논문지 P Vol.55 No.4

        In this paper, an auto detection method of stator winding fault of small induction motor is suggested. The Park's vector pattern which is obtained from 3-phase current signal by d-q transforming, is very good to detect winding fault. Comparing the Park's vector pattern of testing motor with its of healthy motor, the Park's vector pattern of fault motor is became an ellipse and the asymmetry is increased by the winding fault serios. So for detecting the dis-symmetry, id-filtered function, Min-value, and Max-value are suggested for auto detecting. Using LabVIEW programing, 3-phase healthy motor and several kind of winding fault motors are tested and the test results are shown that the suggested method can gives us a possibility of an auto detecting winding fault.

        Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

      • 우리나라의 組稅體系에 관한 考察

        朴東局,朴日圭 東亞大學校 大學院 1986 大學院論文集 Vol.11 No.-

        During the last two decades, the fiscal policy has contributed to the economic growth of the export-oriented economy. financial aid to and export subsidies to the export-industries raised the tax burden ratio to GNP, the rigidity in the expenditure structure. It also the equity of tax-burden distribution. Given the rising revenus needs, especially in response to the potential need for social welfare finance, the optimal ratio of tax-burden to GNP, and its equitable allocation should carefully deteermined. We suggest the following criteria on the optimal tax-burden and the efficiency of resource allocation. (1) Inefficiency in the tax-system, distortions of resources allocation should be reduced in the process of raising the ratio of tax-burden due to the rising revenus needs. (2) The complementary efforts should be made in the tax-structure. :the proportion of direct tax should be raised and the regressiveness of indirect tax should be reduced by increasing income tax and proper tax. (3) In order to increase the revenus and the equity of tax-burden distribution, the scope of non tax and tax-reduction should be curtailed.

        박소진,박영신,황태원,한규진,오종혁,원동복 忠南大學校 産業技術硏究所 2001 산업기술연구논문집 Vol.16 No.2

        정적인 융점측정 방법으로 benzene+n-dodecane, cyclohexane+phenol, phenol+water, water+sulfolane 및 diethylcarbonate+nitrobenzene계에 대한 고액 평형을 측정하였다. 측정된 고액평형 데이터는 문헌값과 modified UNIFAC에 의해 예측된 값과 비교하였으며, 추산값과 실험값은 ±1.61K 범위에서 잘 일치하였다. 본 연구에서 고찰된 diethylcarbonate의 융점은 기존문헌치와 큰 편차를 보여 재검증이 필요하다. Solid-liquid equilibrium(SLE) data were measured for benzene+ n-dodecane, cyclohexane+phenol phenol+water, water+sulfolane, and diethylcarbonate+ nitrobenzene systems by using static melting point measuring method. Measured SLE data were compared with the literature values and also compared with the values predicted by modified UNIFAC(Dortmund) equation. The experimental results are in good agreements with the published and estimated values, and the average deviation between the experimental values and the calculated values is ±1.16K. The measured melting point of diethylcarbonate shows some difference from literature value, and it will be certified through other experimental data for different systems.

        박성태,김상열,황동용,홍연규 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.3

        벼 농사에서 기계화가 어려운 육묘를 못자리 없이 간편하고 저비용으로 할 수 있는 육묘기 개발 및 개발 육묘기의 실용성 평가시험 결과를 요약하면 다음과 같다. 1. 개발 조립식 육묘기는 파종상자 치상선반, 플라스틱판, 부직포와 비닐로 만든 보온덮개로 구성되어 있고 35상자 육묘용 육묘기는 규격이 가로 152㎝, 세로 63㎝, 높이 147㎝이며 무게 75㎏이며, 육묘일수에 따라 육묘선반 간격을 간단히 조절할 수 있다. 2. 개발 육묘기를 이용 육묘시 묘소질은 관행 못자리 모와 비슷하고 결주율는 3.2%로 못자리 육묘상자모 2.8%와 거의 같았다. 3. 개발 육묘기는 대당 20만원정도로 기존 자동화 육묘시설 (198평:7,360상자 육묘기준 및 장비에 비하여 시설비가 43% 절감 된다. 4. 육묘 노력시간은 개발 육묘기는 ㏊당 7.9시간으로 자동화 시설육묘 및 못자리 육묘에 비하여 각각 18%, 76%절감 되었다. 5. 물 사용량은 개발 육묘기 이용 육묘는 ㏊당 2.5kl로 자동화 시설육묘 및 못자리 육묘에 비하여 6~8배 절감되었다. Raising seedling in nursery bed needs not only a lots of time but also labor input which are hard especially to the old and lady farmers. On the other hand, construction of seedling raising facilities such as automated seedling raising house also requires a lots of money. To overcome those problems, a simple seedling raising shelf, which is not necessary for preparation of the seedling raising nursery bed, was developed and its feasibility of seedling raising was evaluated. The dimension of the seedling raising shelf has 152㎝ in length by 63㎝ in width with 147㎝ in height. The shelf is composed of 6 to 7 layers of shelf frame, plastic tray for seedling raising, water supply pipes and white polyester cover. The height of a seedling raising shelf can be adjusted to 6 or 7 layers simply by changing the height of plastic pipes. One unit shelf can accomodate 30 to 35 seedling trays which can transplant about 1000 ㎡ rice field. The seedling height and dry weight of rice seedling grown in the shelf-type seedling raising apparatus was not significantly different from those seedlings grown in the conventional nursery bed. Missing hill percent-age of the seedling grown in shelf-type seedling raising apparatus was 4.3% similar to that of nursery bed of 4.3%. The seeding raising shelf has following advantages. The seedling raising shelf reduces cost of the seedling raising facilities by 43%, labor input hour by 18%, irrigation water saving by 83% versus automated the automated seedling raising house and labor saving by 76% and irrigation water saving as much as 6~8 times versus the conventional seedling raising method of nursery bed.
