The purpose of this study was to investigate the difference of the morphological diagram by Sasang Constitutions and compare with Huh's morphological diagram, a theory based on the Four Cho Theory(四焦設) by Lee Je-Ma. We classified the Sasang Constitutions of 104 Korean College Students(average age 23.81) using QSCC II. Before measuring of morphologic diagrams, we exert the subjects to take supine position on the bed, and make it a rule that our staffs mesure each people directly. The 50% of the total subjects was Soeumin, 26.9% was Soyangin and 23.1% was Taeumin, our study shows the higher percentage than the other studies in Soeumin. The results as follows ; In the cases of man, Taeumin have more developed Low-Middle Cho(the interval between stomach line and Navel line) than other constitutions, whereas Soeumin has more developed Low cho(the interval between Navel line and Ilium line). In the cases of woman, there is no significant difference of Huh's morphology diagram among three Sasang constitutions. We analyzed the difference of obesity among sasang constitutions, and we found that the BMI(Body Mass Index$(Kg/m^2)$) of Taeumin was significantly higher than other constitutions in male. But there was no significant difference among Sasang constitutions in female. We have not found the exact accordance between the real measurement and Huh's Theory. But for man, there are several statistically significant results, indicating the usefulness of the Huh's Morphological Diagramming theory on the discriminating ability of Sasang Constitutions Classificaton. So this results suggest that the use of the Huh's theory should be improved in the classification of the Sasang Constitutions, considering the difference of morphology by sex.

Morphological characteristics of the Eucommia barks produced in Korea and China and of the barks of Euonymus japonicus $T_{HUMBERGI}$ in Korea and Euonymus pellucidifolia $H_{AGATA}$ in Taiwan were compared. The similarity in morphological features between Eucommiae Cortex produced in Korea and that of China suggests that both plants are of same botanical origin. However, the size of tissues and cells indicates that there is only one difference due to warm climatic environment. The similarity and difference of the barks of Euonymus japonicus produced in Korea and Euonymus pellucidifolia produced in Taiwan comfirmed that the two plants belong to the same genus and that they are different species.

Various Cu films were fabricated using sputtering and electroplating with and without additive, and their surface damages after annealing were investigated. After annealing at 43SoC, the difference between damage morphologies of the films was observed. In some films stress-induced grooves along the grain boundaries were observed, while in the others voids at the grain boundary triple junctions were observed. It was also observed that the stress-induced groove was formed along the high energy grain boundaries. It was found out that the difference of the morphologies of surface damages in Cu films depends on not process type but grain boundary characteristics. To explain the morphological difference of surface damages, a simple parameter considering the contributions of grain structures and grain boundary characteristics to surface and grain boundary diffusions is suggested. The effective grain boundary area, which is a function of grain size, film thickness and the fraction of high energy grain boundaries, played a key role in the morphological difference.

Object : Patients with facial asymmetry accompanying mandibular prognathism have various causes and clinical features. So, it is difficult to find a satisfactory treatment method functionally and esthetically. Every traditional classification and interpretation to find etiopathogenesis and/or to establish ideal surgical modality has many limitations because it can't be applied simply to various conditions of patients with facial asymmetry accompanying mandibular prognathism. Therefore, we employ a new classification to interpret more details of the morphologic change of mandible and the spatial change of mandible and maxilla. Materials and Methods : Using panoramic X-ray films, PA cephalograms and submentovertex films of 126 patients diagnosed with facial asymmetry accompanying mandibular prognathism as resources, the following results were gathered after analyzing each characteristics through distributing the patterns according to the morphological mandibular asymmetry and mandibular and maxillary spatial asymmetry. Results : Almost frequency of morphological mandibular asymmetry was shown. In case of condyle-ramus elongation and body elongation group, it's frequency was the highest. Higher frequency of compensating vertical growth was shown on the side of over growing maxilla in case of vertical length difference between left and right condyle-ramus. On the other hand, higher frequency of no compensating vertical growth difference between left and right side was shown in case of no vertical length difference in condyle-ramus. Spatial mandibular asymmetry generally occurred when there was no morphological mandibular asymmetry. Correlation between condyle length difference and condyle-ramus length difference between left and right side was very high, but correlation between condyle length difference and body length difference, and correlation between condyle length difference and body vertical length difference was low. Conclusion : In case of patients with facial asymmetry accompanying mandibular prognathism, it is suggested that various pattern of facial asymmetry is occurred by the independent growth of each unit rather than dependent growth of other unit by major growth unit abnormality. Due to the untypical pattern and the various asymmetry occurring according to the changes of each mandibular growth unit, it is considered that an appropriate surgical method should be searched based on the accurate recognition of the each pattern for patients with facial asymmetry accompanying mandibular prognathism.

한반도와 일본에 서식하는 왕거머리말(Zostera asiatica Miki, Zosteraceae)의 서식 환경에 따른 형태적인 변이를 분석하기 위해 동해연안과 일본 훗카이도에 서식하는 왕거머리말의 식물체와 서식지의 해수 및 퇴적물을 채집 분석하였다. 본 조사를 통하여 왕거머리말은 한반도 지역에서는 수심 8.5∼10 m의 개방된 만과 외해의 영향을 직접 받는 지역에서 주로 서식하며, 동해연안의 공현진리, 동호리, 그리고 영동과 칠포 지역이 왕거머리말의 새로운 자생지로 확인되었다. 그러나 일본 홋카이도의 아케시만(Akkeshi Bay)에 있어서는 한반도와는 달리 1.5∼3m의 수심이 얕은 내만에서 서식하였다. 한반도 동해 연안에서 왕거머리말의 서식지 퇴적물의 입도는 모래로 구성되었다. 한반도 동해 연안의 집단에서는 식물체의 높이가 64.0∼75.7cm, 폭 11.0∼l5.0 mm로 나타났으나, 아케시만에 서식하는 식물체 집단의 높이 187∼234 cm, 폭은 18.0∼l8.7 mm로, 후자의 경우가 훨씬 큰 것으로 나타났다. 이러한 변이에 의해 규정된 한반도 동해연안의 집단간 그리고 일본 아케시만의 집단간핵 리보소옴 DNA의 ITS 염기서열 비교 분석에 의한 유전적 차이는 없는 것으로 나타났다.

12 populatiDns of Ch indicum L. and it's variation antogenous in Tforea were selected throughout the country and their morphological characteristics were studied in this paper. The results are as follows. 1) The mean of the plant height is 97.3cm. Ch. indicunl is 76.5cm and Ch. boreale is 116. 6cm in height. The number of nodes is 58 on the average. The color of the stem is generally black-red in the case of Ch. indicum and is green for Ch. boreale. 2) The leaves of Ch. inficum are smaller In size and thicker than chose of Ch. boreale, and it has a stipule. This fact enables us to distinguish one species from the other, however, the Gyukpo-population of Ch. indicum has a large leaf, and Byunsan-population of Ch. boreale has a stipule so that the above fact is not an exact criterion on which to base one classification. 3) The size of the capitulum is 24.9mm for Ch. indicum and 15.6mm in the case of Ch. boreaje so that the difference between species is admitted. It was confirmed hat the size of the capitulum has positive correlation to that of the pedicel and has egative correlation to the number of flowers, so that of inflorescence, Ch. indicumhas corymb, and Ch. boreale has crowed corymb or umbel-type.The number of ligulates is 19 on the average, which no the difference being founnd between species and populations.4) The cluster analysis of morphological characteristics showed that Ch. indicum wasdivided into two groups, which was shown thought to be due to the difference of speciesbetween Ch. indicum and Ch. boreale. However, it could not be shown that their morphological characteristics explain a geographical relationship between populations

This study aimed to determine whether hormonal hypersecretion could cause morphological problems in the mouse vagina and affect the ovaries and nearby extra uterine organs. All mice were synchronized to estrus before the experiment. Then human chorionic gonadotropin (hCG), progesterone, and testosterone were continuously administered for about 6 days to maintain hormone hypersecretion, and then morphological changes were analyzed, and Matrix metalloproteinases (MMPs) activity and Casp-3 expression were evaluated. As a result of the analysis, in the case of hCG, the morphological change did not show a significant difference from the vagina of normal estrus. In the case of progesterone, changes were observed in the mucosa zone and basal membrane, and it was confirmed that the activity of MMPs was increased in squamous epithelium cells. On the other hand, in the case of testosterone, overall changes in vaginal tissues were observed, and MMPs activity was increased to a very high level in all sections. The expression of Casp-3 was also the highest compared to other groups. Therefore, as a result of this study, it is thought that hormone hypersecretion affects the morphological changes of the vagina other than the ovaries and uterus and induces the activity of MMPs to cause morphological degeneration of tissues.

This paper proposes a new automatic detection method to inspect mura defects on display film surface using morphological image processing and labeling. This automatic detection method for mura defects on display films comprises 3 phases of preprocessing with morphological image processing, Gabor filtering, and labeling. Since distorted results could be obtained with the presence of non-uniform illumination, preprocessing step reduces illumination components using morphological image processing. In Gabor filtering, mura images are created with binary coded mura components using Gabor filters. Subsequently, labeling is a final phase of finding the mura defect area using the difference between large mura defects and values in the periphery. To evaluate the accuracy of the proposed detection method, detection rate was assessed by applying the method in 200 display film samples. As a result, the detection rate was high at about 95.5%. Moreover, the study was able to acquire reliable results using the Semu index for luminance mura in image quality inspection.
