본 연구는 풍납토성 출토 백제토기를 대상으로 현장에서 소성온도에 따라 토기를 분류할 수 있는 외형관찰 기준을 마련하는데 자연과학적 데이터를 활용하고자 하는 연구이다. 소성온도는 토기의 경도, 밀도 풍을 포함한 다양한 물리화학적 특성에 영향을 미친다. 이 중 현장에서 측정이 가능하고 유용한 것이 경도이다. 그러므로 우리나라의 발굴현장에서 적용하고 있는 경도 측정기준을 적용하여 토기를 분류하고, 자연과학적 분석을 통하여 이들 토기의 마이크로비커스 경도, 밀도, 흡수율, 조직의 유리질화도, 광물학적 특성 등을 측정하여 현장에서 적용하는 경도분류 기준과의 상관관계를 비교연구하였다. 그 결과, 발굴현장에서 동전의 긁힘에 의해 주로 행해지던 연질과 경질의 이분법적 분류는 연질과 연경질, 경질의 세 단계로 세분됨을 알 수 있었다. 소성 온도 추정 결과, 연질은 1,000˚C 이하, 연경질은 1,000~1,100˚C, 경질은 1,200˚C 이상에서 소성되었을 것으로 판단된다. 한편, 3단계로 분류되는 토기들의 각 단계별 외형적 공통점을 추출하여 자연과학적인 정밀분석 없이 육안관찰만으로 토기를 3단계로 분류할 수 있는 관찰기준의 제시를 시도하였다. 이러한 기준은 파괴분석을 하지 않고도 토기의 외형적 특징을 이용하여 토기의 대략적인 물성과 소성온도 추정을 가능하게 할 것으로 기대된다. 단, 이러한 기준은 풍납토성에서 출토된 한성백제시기의 토기 중에서 배류와 호류 등 색상이 단조로운 제한된 기종을 중심으로 한 결과라는 한계를 가진다. 따라서 추가적으로 여러 기종의 다양한 색상을 가진 토기들을 대상으로 풍납토성 출토 토기의 경도별 분류가 가능하도록 수정·보완하는 연구를 진행할 예정이다. Observation methods of appearance were studied to establish a systemized classification criteria according to the firing temperatures of excavated earthenware from the Pung-Nap Mud Castle. A firing temperature has an impact on various physical and chemical properties including hardness and density of earthenware. Of all the properties, hardness can be measured in situ. Therefore, the earthenware were categorized according to the measurement method of hardness which can be applied and useful method for archaeological sites. In addition, the correlation between the measurement method and micro Vickers hardness, absorptance, degree of vitrescence and mineralogical properties of the earthenware were studied by means of a natural scientific analysis. The result suggests that the dichotomous way of classification based on a scratching method determining whether it is hard or soft should be categorized into three stages; soft, soft/hard and hard. According to the presumption of the firing temperature, it is believed that the earthenware were fired at below 1,000℃, 1,000~1,100℃ and 1,200℃ respectively. The systemized observation method was proposed to enable the earthenware to be categorized into three stages using visual observation without a detailed scientific analysis. The method will make it possible to estimate roughly the physical properties and firing temperature of the earthenware with only visual observation. However, it has limits as it was established focusing on certain types such as Cups and Jars among the Han-Sung Baek-Je earthenware. Therefore, a further study is planned to be carried out on various objects excavated from Pung-Nap Mud Castle in order to enable categorization on the basis of hardness of the earthenware.

Purpose : To find out the proper compression ratios without degrading image quality and affecting lesion detectability on diagnostic images used in dentistry compressed with JPEG 2000 algorithm. Materials and Methods : Sixty Digora periapical images, sixty panoramic computed radiographic (CR) images, sixty computed tomographic (CT) images, and sixty magnetic resonance (MR) images were compressed into JPEG 2000 with ratios of 10 levels from 5 : 1 to 50 : 1. To evaluate the lesion detectability, the images were graded with 5 levels (1: definitely absent; 2: probably absent; 3: equivocal; 4: probably present; 5: definitely present), and then receiver operating characteristic analysis was performed using the original image as a gold standard. Also to evaluate subjectively the image quality, the images were graded with 5 levels (1: definitely unacceptable; 2: probably unacceptable; 3: equivocal; 4: probably acceptable; 5: definitely acceptable), and then paired t-test was performed. Results : In Digora, CR panoramic and CT images, compressed images up to ratios of 15 : 1 showed nearly the same lesion detectability as original images, and in MR images, compressed images did up to ratios of 25 : 1. In Digora and CR panoramic images, compressed images up to ratios of 5 : 1 showed little difference between the original and reconstructed images in subjective assessment of image quality. In CT images, compressed images did up to ratios of 10 : 1 and in MR images up to ratios of 15 : 1. Conclusion : We considered compression ratios up to 5 : 1 in Digora and CR panoramic images, up to 10 : 1 in CT images, up to 15 : 1 in MR images as clinically applicable compression ratios.

전립선 기질세포의 증식과 COX-2 발현에 대한 프로게스테론의 영향

정수련,김성한,최이화,박지은,전은미,강영진,이광윤,최형철 영남대학교 의과대학 2006 Yeungnam University Journal of Medicine Vol.23 No.1

전립선비대증은 노인 남성에서 흔히 유발되는 질환이며, 노화가 진행될 수록 빈도가 높아지는 특징을 가진다. 이 질환의 원인은 전립선기질세표의 과도한 증식으로 유발된다고 알려져 있지만 그 자세한 기전에 대해서는 잘 알려져 있지 않다. 전립선비대증에서 progesterone 수용체 양성 세포가 다른 전립선 종양에 비해서 많고, progesterone은 testosterone에서 DHT로 전환되는 것을 감소시키는 역할을 가진다고 알려졋다. 또한 남성 전립선 평활근의 과증식에 의한 질환이므로 평활근 세포의 증식과 관련성이 있다고 보고된 COX-2의 전립선비대증에 대한 영향에 대한 연구가 필요하다. 전립선 기질세포에 progesterone을 3일간 투여하여 배양한 경우 기질세포 증식은 차이가 없었다. Progesterone을 단독 또는 DHT와 같이 투여한 기질세포에서 남성호르몬 수용체 mRNA 발현은 비처리군과 비교하여 유의한 차이가 없었다. 또한 progesterone과 DHT 동시 투여에 의한 COX-2 mRNA 발현에도 차이가 없었다. 그러나 progesterone에 의한 남성 호르몬 수용체와 COX-2 단백 발현에서는 대조군과 비교하여 유의하게 감소시켰다. 이상의 결과는 progesterone은 남성호르몬 수용체에 대해 전사 후 반응 (post-transcriptional response)에 효과를 나타내어 남성호르몬 수용체 발현을 감소시키는 작용은 가지며, COX-2 발현 억제효과를 나타내므로 전립선비대증의 치료에 이용될 수 있을 것으로 사료된다. Background: Benign prostatic hyperplasia (BPH) is the most common benign tumor in older men; the etiology of this disease remains poorly understood. Testosterone and dihydrotestosterone (DHT) both act as androgen via a single androgen receptor. Testosterone is converted to DHT by 5α-reductase in prostatic stromal cells. Progesterone has been reported to inhibit DHT conversion; howevwe, its effect on prostatic stromal cells remains to be elucidated. Materials and Methods: In this experiment, we investigated the effect of progesterone on androgen receptor expression induced by DHT. We also tested the effect of progesterone on cyclooxygenase-2 (COX-2) expression, as well as prostate stromal cell proliferation using the cell count kit-8. Results: Progesterone did not cause an increase of prostate stromal cell proliferation. The mRNA expression of the androgen receptor and COX-2 were not changed by progesterone; the expressions of androgen receptor and COX-2 proteins were decreased by progesterone in prostate stromal cells. Conclusion: These results suggest that in prostate stromal cells, progesterone decreases androgen receptor protein expression, which results in decrement of COX-2 protein expression. This effect might be mediated by post-transcriptional regulation.

Cu(Ⅱ)이온과 Poly(vinyl alcohol)간에 생성되는 고분자-금속 착물의 열역학적 거동에 관한 연구

전은덕, 한정호, 조태섭 영남대학교 기초과학연구소 2000 基礎科學硏究 Vol.20 No.-

The dissociation constants for poly(vinyl alcohol) (PVA) at a constant ionic strength of μ=0.1(KCl) were measured by potentiometric titration at various temperatures. The formation constants for the Cu(II)-PVA complex at the same condition were also measured in this study. From the temperature dependence of those dissociation and formation constants, various thermodynamic parameters such as ΔG, ΔH, ΔS were determined. From the thermodynamic parameters, it was concluded that the dissociation of a proton from PVA is unfavorable with a negative entropy and positive enthalpy. In contrast, the complex formation was a spontaneous and exothermic process with favorable entropy.
