  • 본 연구에서는 고소성토 비배수강도와 주요 특성치들의 관계에 대하여 다양한 현장 및 실내시험 결과를 활용하여 심층적으로 고찰하였다. 소성지수, 활성도, 함수비 및 유효단위중량 등은 비배수강도 및 정규화 비배수강도 경우 모두 예상과 달리 특별한 관계를 보이지 않았다. 과압밀비, 예민비 및 비배수탄성계수 등은 정규화 비배수강도와 분명한 관계를 보여주었다. 정규화 비배수강도 방법이 비배수강도와 특성치들의 연구에 크게 도움이 될 것으로 기대된다.

  • Objectives : The purpose of this study was to investigate the possibility of Bi-Su as a pattern identification (PI) index in stroke patients. Methods : The subjects were 424 hospitalized stroke patients within 1 month from onset and diagnosed with the same PI subtypes (dampness & phlegm, qi deficiency, fire & heat, eum deficiency, and blood stasis) by agreement of two clinical experts. Bi-Su type is a kind of body shape (Bi : fat, Su : lean). Bi-Su type and degree (Bi-Su score) were decided by clinical expert. Body mass index (BMI) and waist-hip ratio (WHR) were used as an obesity index. Correlation analysis between Bi-Su score and obesity index (Spearman) and variance analysis for Bi-Su score, BMI, and WHR among PI subtypes (ANOVA) and sex were carried out. Results : While there was partial correlation between Bi-Su type and BMI($r^2$=0.634, p<0.001), the distribution of the BMI group based on the Bi-Su group showed the broadest range. The Bi-Su score in the dampness & phlegm group was higher than in the other groups (p<0.001). BMI in the dampness & phlegm groups was also higher but the BMI differences among PI subtypes was low (p=0.002). The Bi-Su score in the dampness & phlegm group was similar in both sexes, although the hand score in the eum deficiency group was the lowest, especially in males. Conclusions : Although BMI is not an objective enough tool for evaluating Bi-Su type, Bi-Su type is more appropriate than BMI as PI index. Therefore Bi-Su type could be used as one of the PI indices for dampness & phlegm or eum deficiency group in stroke patients.

  • The nan gyeong(難經) is another name of hwang je pal sib-il nan gyeong(黃帝八十一難經) which is book of traditional oriental medicine that contains many medical theories. This thesis studies 'su-hyeol'(兪穴) that is recorded in the books. 1. '62th nan' contains that um-gyeong(陰經) has five su-hyeols and yang-gyeong(陽經) has six su-hyeols. 2. '63th nan' contains why Jeong-hyeol(井穴) starts at first among the five su-hyeols. 3. '64th nan' appears su-hyeol's character and explains it's reason. 4. '65th nan' discusses that some divisions of su-hyeol's character correspond with the climate. 5. '66th nan' explains the importance of 'Won-hyeol(原穴). 6. '67th nan' appears the eum-yang's character of 'Mo-hyeol'(募穴), eum-yang's character of 'Bae-suhyeol'(背兪穴), it's situation and it's pathological significance. 7. '68th nan' explains the stream of 'su-hyeol' in twelve meridians and it's symptoms of a disease. The Nan gyeong(難經) has the difficulty in it's contents and many scholars take charge of that differently. In that reason, each argument is subjectly. This thesis unites scholar's arguments of 'Su-hyeol'(兪穴) as many as possibly and investigates their differences objectively.

  • This study has been carried out to investigate the cause, symptom and treatment of Gi-Su(氣嗽) by referring to 20 literatures. The results were as follows; 1. The factors causing Gi-Su(氣嗽) divided into 3 groups. The 1st outer factors are mental element, 2nd spleen week 3rd dam(痰). 2. The symptom of Gi-Su(氣嗽) is as follows. stimulus feeling in throat, cough, pain of sub-ribs, bad feeling, retching, vomiting, unfair, fatigue, worn, diarrhea, dark tongue, makhyun(脈弦). 3. The treatment of Gi-Su(氣嗽) is as follows. gaewulhanggi(關鬱行氣), egichungpae(利膈淸肺), hwadam(化痰), soganhaeWul(疏肝解鬱), hanggidoche(行氣導滯), sangyuljedam(散結除痰) 4. The drugs of Gi-Su(氣嗽) is as follows. chilgitang(七氣湯), gamisachiltang(加味四七湯), sojaganggitang(蘇子降氣湯), banhahubaktang(半夏厚朴湯).

  • 본 연구에서는 SU-8을 절연층으로 사용해 솔루션 공정을 바탕으로 하여 Indium Zinc Oxide(IZO) thin film transistor(TFT)의 안정성을 향상에 대해 연구하였다. 매우 점성이 강하며 negative lithography 용으로 사용되는 SU-8은 기계적, 화학적으로 높은 안정도를 가진다. 그리고 이 SU-8을 사용해 TFT층의 위에 스핀코팅을 사용해 절연막 층을 쌓고 photo lithography를 이용해 patterning을 하였다. SU-8층에 의한 positive bias stress(PBS)에 대한 전기적 특성 향상의 이유를 연구하기 위해 TFT에 X-ray photoelectron spectroscopy(XPS), Fourier transform infrared spectroscopy(FTIR) 분석을 시행하였다. SU-8을 절연층으로 한 TFT는 좋은 전기적 특성을 보였으며, 전류점멸비, 전자이동도, 문턱전압, subthreshold swing이 각각 $10^6$, $6.43cm^2/V{\cdot}s$, 7.1V, 0.88V/dec로 측정되었다. 그리고 3600초 동안 PBS를 가할 시 ${\Delta}V_{th}$는 3.6V로 측정되었다. 그러나 SU-8 층이 없는 경우 ${\Delta}V_{th}$는 7.7V 였다. XPS와 FTIR을 분석한 결과, SU-8 절연층이 TFT의 산소의 흡/탈착을 차단하는 특성에 의해 PBS에 강한 특성을 나타나게 함을 확인하였다.
