Capacitor 위치 조정 시스템 개발

송해길,윤성일 공주영상정보대학 1999 논문집 Vol.6 No.-

본 연구는 극성 판정 후 위치를 자동으로 조정할 수 있는 시스템으로 극성 판정의 알고리즘을 중심으로 기술하였다. 위에서 살펴본 모델는 6000기 라거 타입 콘덴서를 기준으로 개발하였다 이 모델 이외에도 여러 가지 콘덴서의 종류가 있는데 추가로 삽입되는 모델는 7000기 모델이며 이는 콘덴서의 벨트가 존재하지 않으므로 단자에 새겨진 극성을 가지고 판정해야 한다. 패턴 매칭은 위에서 살펴보았듯이 신뢰도가 떨어지므로 적용할 수 없음을 살펴보았다. 이 모델을 검사하기 위해서는 최대한 영상을 선명하게 기구적인 조정이 필요하며 특징치가 잘 나타나도록 영상의 전처리가 필요하다. 현재 콘덴서 위치 조정 시스템은 독일 지멘스의 콘덴서 제조 라인에 탑재되어 있고 7000기 모델을 추가로 개발 중에 있다.

X선을 이용한 물체의 단층 영상 구현과 합성 알고리즘 개발

송해길,윤성일 공주영상정보대학 1998 논문집 Vol.5 No.-

본 논문에서는 X선을 이용하여 3차원 물체의 단면을 구할 수 있는 방법을 제시하고 영상의 선명도와 정확도를 높이기 위해서 합성 알고리즘을 제안하였다. 단층 구현 원리에 의해 8방향에서 프로젝션된 영상을 3가지 합성 알고리즘을 적용하여 선명도와 정확도를 판별하였다. 이 평가 알고리즘에 의해서 X선 단층 영상 시스템에서는 제곱근 평균법이 비교적 높은 정확도와 물체를 인식할 수 있는 영상의 선명도가 좋다는 것을 알 수 있었다.

Kidney secrete of urine. The chief ingredients of urine are H_2O, solid, urea, creatinine, ketone, oxalate, glucuronate, NACL & Nitrogen compound. Fixed quantity of this ingredients is only representatives. The result of this test sharply changed by food or health condition. Therefore, this result appears the function of kidney.

Microarray 자료의 통계적 표준화 방법의 비교

송혜향,윤상헌,김제석 한국보건통계학회 2003 보건정보통계학회지 Vol.28 No.1

Microarrays can provide detailed information of the expression patterns of thousands of genes in tumours, but due to systematic variations such as dyes, hybridization and processing precedures, and technical attefacts, true biological differences in gene expression levels cannot easily be detected. If the vast quantity of these microarray data can be suitably normalized, the impact of this genomic expression data on the understanding of diagnosis and treatment of disease will be profound. Statistical normalization approaches to microarray data are not as yet fully explored and need to be continuously evaluated. We compared the currently much used normalization methods and recently proposed statiostical normalization methods of ANOVA with oligonucleotide microarray data of hepatic nocular lesions indluding hepatocellular carcinoma. This article proposes combined normalization methods of ANOVA after a robust local lowess, intensity and print- tip dependent, regression.

Purpose: This study was aimed to specify roles of nurses from the anesthesia and recovery room by analyzing nursing activities as well as anesthesia nursing during surgery. Method: The objects were 12 RNs working in the recovery room of a university hospital located in Incheon. Self-report was performed by measuring stop-watch for five days from May 17th to May 21st in 2004. Research method was designed to record the time and frequency of the nursing activity from anesthesia and recovery room based on nurses' statement and other references for five days. The data were analyzed with descriptive statistics, ANOVA, and t-test via SPSS Win 10.0 program. Result: Nursing activities in anesthesia recovery room were classified into two different characteristics such as direct and indirect nursing activity. The activities consisted of 11 direct nursing areas and 39 nursing activities in anesthesia preparation room. The indirect nursing was classified into 8 nursing areas and 32 nursing activities. The direct nursing was classified into 12 nursing areas and 55 nursing activity. Also, the indirect nursing was classified into 7 nursing areas and 21 nursing activities in recovery room. In terms of prevalence of nursing activities in the anesthesia preparation room, observation and cooperation of anesthesia was the most prevalent activity, drug and eqipment management the second prevalent, and drug administration the third. On the other hand, in the recovery room, the most prevalent activity was vital sign checking and observation, the second most prevalent activity informative activity, and the third body temperature control. Nursing activity time was recorded according to the nursing characteristics. In the anesthesia preparation room, the direct nursing spent for 8092.20 minutes was larger than the indirect nursing spent for 7198.50 minutes. Also, in the recovery room, the direct nursing spent for 2361.16 minutes was larger than the indirect nursing spent for 1134.13 minutes. 4. Nursing activity time was compared to duty shifts. In the anesthesia preparation room, the direct nursing was more prevalent on day shift and the indirect nursing was prevalent on evening shift. However, in the recovery room, both direct and indirect nursing activities were prevalent on day shift. Conclusion: The role of anesthesia and recovery room nurses was analysed according to the time, frequency, and its characteristics.

Objectives : The purpose of this study was to investigate the prevalence of erectile dysfunction (ED) in a rural area of Korea and to examine the relationship between the prevalence and correlates of subjects. Method : This study was done as a part of the chronic disease survey of rural area by the Asan Foundation. Among 30 years or older population from Jung Eup, a rural area of Korea, 711 male subjects were sampled using a cluster probability sampling method. Trained interviewers visited and interviewed subjects aged 30 years or older with a structured interview. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. Response rate was 54.3% (N=386). Results : The age weighted prevalence of ED was 27.2% (minimal 14.1%, moderate 7.6%, severe 5.5%). Prevalence and severity increased with age. Liver disease and underweight were significantly (p<0.05) associated with ED. Smoking seemed to be correlated with ED, but did not reach statistically significant level. Conclusion : ED was highly prevalent in the rural community of Korea. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology.

이형직,송두규,권혁병,정해경,윤상옥,이형복,이홍림 국립7개대학공동논문집간행위원회 2003 공업기술연구 Vol.3 No.-

소결첨가제나 바인더를 넣지않고 만든 무첨가 PZT 분말 성형체를 플라즈마 소결-로 열처리 후의 미세조직의 변화, PbO의 거동 그리고 이에 따른 유전특성을 로소결한 경우와 비교하여 다음과 같은 결과를 얻었다. 플라즈마 소결-로 열처리로 만든 PZT 시편이 로 소결 시편과 비교하여 입성장이 크게 일어나지 않은 미세조직을 나타내었으며, 또한 균일한 Pb, Zr, Ti 성분분포를 보였다. 유전특성에 있어서는 1kHz에서 20%정도의 유전율의 향상을 얻을 수 있었으며 유전소실 또한 40%정도 낮출 수 있었다. 상기의 결과는 DC 플라즈마 소결법의 특징인 소결초기의 급속가열 효과와 PbO의 증발 억제 효과에 의한 것으로 고려된다. PZT powder compacts without additives and binder were processed by plasma sintering-furnace annealing. Microstructures, PbO behaviour and dielectric properties were investigated, and compared to the specimen obtained by furnace sintering. The specimen prepared by plasma sintering-furnace annealing showed more not only fine microstructures but also homogeneous pb, Zr, Ti composition distribution, and revealed 20% higher dielectric constant as well as 40% lower dielectric loss (measured at 1kHz). Above results might be considered to be caused by rapid heating effects, high temperature sintering effects and preventing effects of PbO evaporation characterized by dc plasma sintering.

It has been known that the obesity related health risk factors are associated with total adiposity as well as the regional distribution of adipose tissue. The purpose of this study was to examine the effects of self-paced aerobic plus resistance exercise program on changes in body composition, in particular abdominal fat, and lipid in thirteen older women. Subjects (65 ~ 78 year) exercised 4 time/week for 12 week. body composition was measured by the impedance method, and regional body composition was assessed by computed tomography. There was little but significant change in body weight (58.6±9.6 vs 57.3±9.6kg, p<0.05), total body fat (34.5±6.8 vs 33.0±5.9%) and subcutaneous fat area (218.3±74.4 vs 213.6±86.4 ㎠) in these subjects. Unexpectedly, visceral fat area was found to increase (115.5±42.0 vs 124.0±49.1 ㎠, p<0.05) after a self-paced exercise program in older women. There were significant changes in the systolic (p<0.01) and diastolic blood pressure (p<0.01), serum levels of total cholesterol (p<0.05) and basal glucose (p<0.05) not in triglyceride. In conclusion, although the internal abdominal adipose tissue and triglyceride did not decrease, these findings provide evidence that self-paced exercise with aerobic and resistance training is an effective intervention to change the subcutaneous fat area and to improve the coronary artery disease risk factors for older persons without diet.
