발전기 고정자 권선 내부의 완전 건조는 누수시험을 위한 필요/충분조건이다. 발전기 운전에 의한 고주기 피로는 미세 균열 발생의 원인이 되고, 미세 균열에서의 물분자는 누설 진단의 신뢰성을 저하시킨다. 이와같은 이유로, 발전기 고정자 권선에 대한 누수시험에서 권선에 누설처가 있음에도 불구하고 누설이 없다는 결론과 같은 오류를 범하고 있다. 발전기 제작사는 누수시험을 고유한 건조 판정 기준을 제시하고 있지만, 실제로는 어떤 판정 기준도 누수시험을 위해 정확하게 건조 판정 기준을 지시하고 있지는 못하고 있는 실정이다. 그 이유는 발전기 고정자 권선의 복잡한 구조와 효과적인 건조 장비의 부재 때문이다. 본 논문에서는 수 냉각 발전기 고정자 권선의 내부 건조 여부를 판정하기 위한 건조 판정 기준을 완벽하게 제안하였으며 실험적으로 증명하였다.

Objectives : This study was conducted to test patients with Atopic Dermatitis by external application with Gynostemma Pentaphyllum MAKINO in cosmetics. Methods : We gave scores to 59 patients who visited the Dept. of Oriental Medical Opthalmology & Otolaryngology & Dermatology of Daegu Hanny Oriental Medical Center from July 1st, 2005 to December 31th. We checked the clinic index score(extent. intensity : the degree of erythema, induration or papulation, puritus, excorination, lichenification, scaling or dryness, erosion or oozing or weeping. the degree of itching), Eosinophil count and IgE. Results : There are 46 patients we could check by clinic index score, and 44 patients by laboratory. 1. In the 46 cases clinic index score was significantly decreased between the before- and afterexternal application treatment periods(P<0.01). 2. The 46 cases was devided into two types (moist heat type and blood dryness type) by intensity. External application of Gynostemma Pentaphyllum MAKINO in cosmetics did not significant change by two types. 3. In the 44 laboratory cases, the number of eosinophil counts was decreased but the number of IgE was significantly increased. Conclusions : Considering the above results, we have concluded that cosmetics with Gynostemma Pentaphyllum MAKINO have the remedical effect for Atopic Dermatitis.

대류권 하부의 높은 대기 불안정도와 건조도에 의해 바람이 강한 조건하에 화재 연료도 건조해지면 산불 통제가 어렵고 대형산불에 의한 더 많은 산림자원과 계산의 손실을 초래할 수 있다. 본 연구에서 제시된 장기간(1979-2005)의 Haines Index는 한반도 상의 대기 불안정도와 건조도의 시공간적 패턴이 우리나라 산불 발생빈도에 중요한 영향을 미치고 있음을 잘 보여주고 있다. 산불 발생빈도와 Haines Index 사이의 지수회귀모델은 주요 산불 발생기간동안(12월-4월)의 Haines Index 일평균 값 혹은 월별 발생빈도가 우리나라 산불 발생빈도와 통계적으로 유의미하게 상관되어 있음을 보여준다. 지리정보시스템(GIS)에서 수치표고모델(DEM)을 고려하여 작성한 Haines Index 기후도에 따르면, 5 이상의 높은 Haines Index는 주로 해발고도 500m 이하의 한반도 북서 저지대를 중심으로 4-5월에 자주 발생하고 있다. 이러한 Haines Index의 발생빈도는 1990년대 중반 이후 한반도 전체적으로 증가하는 추세를 보이고, 특히 경상북도와 동해안 지역을 따라 산불기간 동안 가장 뚜렷하게 증가하는 패턴을 보였다. 연구기간 동안 높은 Haines Index가 2-3일 연속적으로 발생한 극사상(extreme events)이 나타나는 시기의 500hPa 종관 평균도에 따르면, 오흐츠크해에 발달한 한랭저기압이 한반도 중층대기의 기압경도력을 높여 동서의 강한 바람장을 형성하는데 도움을 주고 있음을 알 수 있다. 이러한 결과들은 현재 우리나라 산불 예보 시스템에 대기 불안정도나 건조도와 같은 대기의 수직적 요소들의 시 공간적 특성도 고려되어야 하는 필요성을 잘 보여준다.

산림지역에서의 관측은 평지에서의 관측에 비해 지상관측에 있어서 어려움을 가지고, 위성 관측자료는 지상의 지점기반 관측자료에 비해 높은 공간 해상도를 가진다. 이러한 이점을 이용하여 위성 관측자료는 산불발생 위험도를 추정하는 연구에 활용되어왔다. 위성 관측자료를 사용하는 여러 산불 관련 지수 중 TVDI(Temperature Vegetation Dryness Index)는 정규식생지수(Normalized Difference Vegetation Index; NDVI)와 지표면 온도(Land Surface Temperature; LST)를 기반으로 산불발생 위험도를 평가한다. TVDI가 기상과 식생의 건조도를 모두 고려하는 장점을 가지고 있지만 선행 연구에 따르면 TVDI는 여러 산불 관련 지수들에 비하여 한반도에서의 산불발생에 민감하지 않은 것으로 나타났다. 본 연구에서는 한반도에서 TVDI의 산불발생 위험도 표현능력을 향상시키기위해 여러가지 개선방법을 적용하였다. 지상에서 측정한 기온을 적용하여 TVDI의 정확도를 향상시키고, 월별로 최대, 최소 온도 회귀선을 구하여 TVDI에 계절효과를 적용하고자 했으며, 각 지역별로 TVDI를 계산하여 식생 유형 및 지역 기후를 고려하였다. 개선된 TVDI는 선정된 산불사례들을 통해 평가되었으며 산불발생 위험도 측면에서 향상된 성능을 보여주었다.

Objectives : Atopic dermatitis(AD) assume an remarkable clinical aspect and it s diagnosis almost depends on clinical symptoms. Therefore, we aimed to study the clinical diagnostic standard of AD for more accurate treatment. We repert as follows; Methods : For 6 months from March to August in 2000 we selected fifty outpatients who were prognosis of AD in the department of dermatology, Oriental medical hospitol, Dong-eui University. Results and Conclusions : 1. We classified of the grade, the condition of AD patient was slight and severe, by the sum of total by the clinical index of AD (diagnostic features). 2. By consulting previous oriental medical theories, we divided symptom-complex of AD into two type ; one was damp-heat type and the other was deficiency of blood- wind-dryness type. 3. Male to female ratio was 17 : 33 and the third stage, more than half of the patients were adolescents. 4. According to the results of symptom-complex of AD patients, on the first examination damp-heat type was more than deficiency of blood-wind-dryness type and in progressing treatment, the condition has been change to deficiency of blood-wind-dryness type. 5. In the lesions of AD, arm and knee were most serious skin lesions and in symptoms of AD, pruritus was most complained, and in progressing treatment, erosion and erythema were greatly improved. 6. When we measured the levels of serum Total IgE, that of thirty eight patientswere higher than that of normal, but elevation of serum IgE levels was not correlated with the severity of AD.

Objective : An adequate measurement for Atopic Dermatitis(AD) is essential for studies about the treatment of AD. To establish a new and adequate scoring system for AD in Korean medicine, we reviewed existing studies on AD outcome measurement in Korean medicine. Method : We searched for reviews on measurements of AD or studies which used an AD outcome measurement at the Korean Traditional Knowledge Portal from 1995 to June, 2008. And then we reviewed the pattern identification in AD patients and the outcome measurements for AD in each study. Results : 1. Among 25 studies, the most common measurement for AD was SCORAD(the severity SCORing of Atopic Dermatitis index), there were 16 studies. There was one study which used the Jakob T scoring system, one study which used ADSI(the Atopic Dermatitis Severity Index), and there were 7 studies which established or used a new severity scoring system for AD. 2. In Korean medicine, AD caused by Damp-Heat is accompanied by erythema, papulation, oozing and crust, Damp-Heat accompanied by Spleen-Gi deficiency is frequently found in pediatric patients, and in adults who have indigestion. Symptoms of AD caused by blood deficiency and Wind-Dryness include lichenification, dryness, scale and pigmentation. AD caused by toxic Heat in the blood system has symptoms similar to some Damp-Heat pattern along with symptoms of blood deficiency and Wind-Dryness. Conclusion : We need to establish a new severity scoring system which reflects pattern identifications and treatments with Korean medicine, and we should assess the validity, reliability, and sensitivity of the new scoring system.

Background: This study aimed to analyze correlations between depression, cognitive function, oral health state, ability to perform activities of daily living, oral dryness symptoms, and oral health-related quality of life, and determine factors influencing the latter. Methods: This was a cross-sectional study based on questionnaires completed by 260 participants with suspected dementia, residing in South Korea. Psychiatrists, psychiatric nurses, and dental hygienists visited clinics in the participating regions for examination and questionnaire administration. General characteristics, the geriatric depression scale, ability to perform activities of daily living, cognitive function, oral health state, and oral health-related quality of life were analyzed. Independent t-tests, one-way analysis of variance (ANOVA), correlation analysis and multiple regression analysis were conducted, identifying factors affecting oral health-related quality of life. Data analysis was performed using SPSS ver. 20.0 (IBM Corp., USA), and the significance was set at p<0.05. Results: Approximately 65.0% of participants were female, 63.5% were in their 70s, and 90.0% had health insurance. About 21.5%, 42.0%, and 36.5% were normal, slightly impaired, and had dementia, respectively. High cognitive impairment was associated with poor oral health. Sex, education levels, marital status, and living arrangements influenced oral health-related quality of life. According to the regression analysis, geriatric depression and oral dryness affected the Geriatric Oral Health Assessment Index scores. Conclusion: In conclusion, oral dryness and depression levels among elders influenced oral health-related quality of life. The results showed that to enhance elders' oral health-related quality of life, it is essential to not only improve their oral health state, but also relieve oral health problems, especially oral dryness, and take into consideration their psychological aspects.

Objectives : Since the program about sodium lauryl sulfate that might cause oral dryness and taste change including oral tissue allergy was on the air, the ingredients of D.I.Y dentifrices without sodium lauryl sulfate have been sold in online shopping mall and ordinary people can make the dentifrices easily. But there have not been any reports about the effect of dental plaque removal and preference about D.I.Y dentifrices. Therefore, this study was designed as a pilot study which aimed to investigate the effect of dental plaque removal and prefernece about D.I.Y dentifrices. Methods : 6 subjects were collected to test the effect of dental plaque removal with D.I.Y dentifrices with written consent. They didn't brushed the teeth during 12 hours until the check-up time on the next day. The O'leary index was calculated in baseline, 1 minute, 2 minute, 3 minute after brusing with D.I.Y dentifrices and market dentifrices. The preference about D.I.Y dentifrices through self-administered questionnaire was surveyed in 51 subjects after using D.I.Y dentifrices. Results : 1. The market dentifrices could remove larger amount of dental plaque than D.I.Y dentifrices, but, it wasn't significant. 2. In feeling refreshment, the market dentifrices had more positive answers significantly. 3. In feeling taste change, the market dentifries had more duration of taste change significantly. 4. In feeling oral dryness, the market dentifrices had more duration of oral dryness after toothbrushing. but, it wasn't significant. 5. As a result about reviewing the dental journals about ingredients of D.I.Y dentirices, green tea, sodium carbonate, bamboo salt, propolis had each evidence. But, We could not find out the evidences of calculus adhesion by corn starch, preservative by napri, disinfectant of peppermint. Conclusions : Although we cannot find the difference of the effect of dental plaque removal between D.I.Y dentifrices and market dentifrices, and D.I.Y dentifrices have the merits of decrease of oral dryness and taste change, it was suggested to have another test about stability and safety of D.I.Y dentifrices for safety of the user of D.I.Y dentifrices.
