The Red Hill deposit of the Dongjom Copper Mine is the most promising deposit of the mine and under intensive exploration at present although there are eight more deposits of vein type. With total 2160m drilling of 9 holes completed and 400m drilling on two holes underway, the nature of the Red Hill deposit has come more clear. The copper content in the whole ore body is meager so far as the exploration done up to present indicates, but there are evidences that mineralization covers all over the granodiorite cupola at the Red Hill area. The petrological work and assay on the samples taken by the writers indicate that granodiorite rocks can be divided into fresh zone and alteration zone. Alteration zone consists of potassic and argillic zones accompanyied by silicification zone on basis of Lowell and Guilbert model Argillic zone has closely related with a mineralization in the Red Hill deposit. It has been cleared that the alteration acompanyied with the mineralization took place not only &long vertical fissures but also in the irregular lateral zone, the nature of which is unknown. Judging from the results of exploration and petrochemical study on the Red Hill deposit which is imbedded in a southern part of the granodiorite cupola, it can be concluded by the writer's opinion that the Red Hill deposit is possibly a porphyry copper deposit, because the shape of the ore body, mineral zoning and paragenesis and wall rock alteration resemble to those of typical porphyry copper deposits. It is the writers' opinion that more exploration work is required so as to evaluate the deposit.

The present study was carried out to evaluate the morphological changes in the degenerating primordial follicles induced by $\gamma$-radiation. The prepubertal female mice of three weeks old ICR strain were whole-body irradiated with a dose of $LD_{80(30)}$ (8.3 Gy). The ovaries were collected at 0 h, 3 h, 6 h, and 12 h post-irradiation. The largest cross sections were prepared with histological semi-thin sections and then observed microscopically. The ratio of normal to atretic follicles was reduced significantly after 6th post-irradiation. At 6 h post-irradiation, the number of degenerated primordial follicles increased. Germinal vesicles disappeared, and lipid droplets increased. No more ooplasmic membranes were seen. Granulosa cells became round in shape, and apoptotic cells started to appear. The ratio of normal to atretic follicles in the control group was 62.50%. The ratio decreased with time after irradiation. The ratio decreased down to 51.61 %, 48.97 %, 11.11 %, and 7.14 % at 0 h, 3 h, 6 h, and 12 h, respectively. Taken together, ionizing radiation acutely induced the degeneration of primordial follicles. The patterns of degeneration are 1) apoptosis of one or more granulosa cells with relatively intact oocyte, 2) apoptosis of oocyte with intact follicle cells, or 3) apoptotic degenerations of both cells. The Present study can provide morphological clues for the identification of degenerating primordial follicles.

Objectives : The uterus plays an important role in the woman's body. In Korean Medical literature, the uterus is mentioned in various contexts according to different perspectives on its meaning and function. An examination of these various contexts is crucial in understanding the meaning of the uterus and to better understand and approach woman's body. Methods : Aside from the most widely used term Jagung(子宮), there were various terms used to refer to the uterus. Based on a list of these terms, the Siku Qianshu collection of medical literatures was investigated. Contents related to the definition, shape, location, function were extracted and examined. Results : Among the findings, first, there were various terms referring to the uterus similar to contemporary understanding. Some of them referred to the uterus as a whole, while others referred to specific parts, one of which is the placenta. Some reflected a broader perspective on the meaning of the uterus. Second, the functions of the uterus could be summarized as gate keeping, and the maintenance of uterine environment that is related to menstruation, pregnancy, and childbirth. Third, based on the examination of the meaning of the uterus and its functions, perspectives on the uterus in Korean Medicine could be summarized into two. Conclusions : One viewed uterus as an organ dedicated to reproduction, similar to today's common understanding. According to this view, uterus is a special organ specific to women, which functions as an incubator for the fetus. The other viewed the uterus as an intangible source of life in the woman's body. As a general source of life to all human beings, it is not a passive organ but functions as an active source in woman's life phenomena. The two perspectives are not in conflict, but rather reflect the broad range of thought on the concept of the uterus in Korean Medicine. In today's biomedical society, the diversity and flexibility of these perspectives could shed light on medical practices that have resulted from extreme views on the woman's body.

Tegumental ultrastructures of Echinochasmus japonicus were observed by scanning electron microscopy. The worms were recovered from albino rats which were experimentally infected with the metacercariae obtained from Pseudorasbora parva. Followings are summarized findings. 1. The worms were minute and plumpy gourdshaped with attenuated anterior and round posterior end. The tegument of whole body was wrinkled transversely and covered with cobblestone-like cytoplasmic processes. 2. Head crown was armed with 24 collar spines which were embedded in cytoplasmic pockets. The spines were arranged in a row with an interruption at dorsomedian line, however, the 2nd and the 4th spines were outstretched more than others. Oral and ventral suckers were muscular with numerous type II sensory papillae, and genital pore opened between the two suckers. 3. Tegumental spines were spade-shaped with broad base and pointed tip. They were compact in ventra-lateral tegument or dorsal surface of anterior body. They were not found between the two suckers and dorsal surface of posterior body. 4. Two types of sensory papillae, uni-ciliated (Type I) and roundly swollen sensory papillae (Type II), were observed. The type I papillae were chiefly distributed on ventral surface of tegument and type II were on the lips of suckers. Arrangement of collar spines, shape and distribution of tegumental spines or sensory papillae are regarded as characteristic features of E. japonicus.

The objects of this experiment are to find out the local variation of the Dendrolimus Spectabilis Butler, of which sample was first collecteted 15 bodies of male and 35 bodies of female adult at Suwon area. the wing veins and the scale shape have been observed through the microscope (100) and the scale size (from the bottom of the scale to the top of the lobe) has also been measured by the micrometer. The results of this experiment are as follows: 1. There is nodifference between the venation of the male body and that of the female body. Also we can not find any differences between the right and the left wing, and between each body. The fore wings consit of 13 longitudinal veins and the only one "V" shape cross vein which is between the 5th and 6th vein. The hind wings consist of 9 longitudinal veins and the only one "V" shape cross vein which is mentioned above. 2. The scale types are divided into 4 Groups in its shape. (A) The scales of I Group are short and the lower parts of them almost look like a circle, having a small projection at their bottom. The upper parts of them have 2 or 10 lobes. We can find the lobes with fine hairs or the lobes without them at the top of the scales. (B) The scales of II Group are longer than that of I Group. The shape of the lower parts of the scales is similar to that of I Group. The upper parts of the scales have 2 or 10 lobes. (C) The scales of III Group are long and almost alike in a long wedgeshape. The upper parts of the scales have 2 Or IO lobes and we can find long fine hairs at the top of each lobe. (D) The scales of IV Group are long and the shape of the lower parts of the scales is similar to that of III Group. The lobes are short and not sharp. We can find 2 or 9 lobes. 3. The scales of I Group and II Group are distributed on the whole surface except on the outer margin. The most scales of III Group are distributed on the wing base. The scales of IV Group are distributed on the outer margin only. The scales with 4 or 5 lobes are most widely distributed not considering their Group or distributing parts. 4. In I Group the variation of the scale length become gradually greater as the number of the lobes are increasing. In II, III, IV Group, however, the variation of the scale length is in direct opposition to the above mentioned. The variation of the scale width becomes pretty small in any Groups and the scale width become wider as the number of the lobes are increasing. 5. The source of the wing colouration is pigmnetal colour, and the wing colouration is expressed by the amount of brown and white scales.

The purpose of this study is to acquire various methods for the fashion image coordination and to examine common features of variation of coordination methods according to the trend. It has attained by investigating Men's fashion image coordination through trend analysis in terms of its coordination features and its variety aspects. For this study, it has classified into twelve typical Men's fashion images in collecting 1,291 pieces of photographs on the subject of jackets and pants from Men's fashion collection$(1995\~2002)$. The study has examined methods and features of fashion image coordination by year according to design elements and the harmony between items. In addition, it has drawn common factors in the image coordination. The summary and conclusion are as follows. A year of 1995, it has presented as the essential code of the variation that morphologic aspects of a design in the fashion image coordination. Various designs have developed through the variation of shapes such as shoulder width, shoulder pad, jacket width and its length and so on. In the initial stage, the width of shoulder and jacket has fitted into large pattern and then adjusted elegantly to make fit the body that indicates a dissolution according to an avant-garde image. At the time that over-measurement of the shape has reduced and high quality and variation of materials has gradually become significant. Those are often used that high-quality glossy materials or other materials which are opposite to the basic code of the original fashion image materials and qualities regardless of images. On the pattern and color, in addition, have represented neat and elegant impression with moderate applications rather than quantitative abundance that have used opposite elements to the basic code f3r the change code like materials. Furthermore, before and after 1999, ' it shows that a concept of the total coordination has arisen that increased coordination methods to strengthen and affluent its images for the whole with wearing accessaries such as hats, gloves, sunglasses, mufflers, bags, belts and so on.

This study was carried out to examine the distribution and habitat of Bibarl snake (Sibynophis Collaris) from March 1998 to June 2005 in Jeju island, Korea. 5 individuals of Bibari snake were observed on northern part of JeJu, 1 individual on southern area and 2 individuals on western area during research period. As a result, it was revealed that Bibari snake was found on the whole of Jeju island. Its observation was made from May to October, especially frequent from May to July. The body length of adult Bibari snakes were $406{\~}452mm$ and its tail length $29+{\~}202mm. Considering of number and shape of supralabials and number of temporals, the characters of Bibari snake were similar to those of S. chinensis. Therefore it seems need to reconstruct taxonomic position of Bibari snake. From a vertical viewpoint of Mt. Halla, Biabri snake prefers to stay on the grassland 600m below the sea. Consequently, it Is suggested that grassland be well-reserved for the protection of Bibari snakes.

As the demand of the consumer for high-sense clothing, relation with materials is becoming important even in clothing construction. Especially, the cutting angle of materials is becoming an crucial element in the formation of silhouette, and drape of Hem line, of skirts. Accordingly, in this study, Hem line shapes between real clothing and 3D virtual clothing of "i-Designer" were analyzed by manufacturing semi-flare skirts of polyester 100% according to a cutting angle, and the results are as follows. As a result of comparison of silhouette between the real clothing and the virtual clothing, the real and the virtual have a similar feeling regardless of a cutting angle. In case of drape shapes, both the front and the lateral side were represented in almost similar shapes. The back side, however, the real and the virtual showed a great difference in case of grain direction. And in the whole silhouette, the real and the virtual were represented similarly. It could be known that with regard to Hem-line drape shapes between the real clothing and the virtual according to a cutting angle, the real clothing is represented in a location farther from the body than the virtual clothing and, the location or number of node was similarly showed in the real and the virtual.

Face detection refers to the process extracting facial regions in an input image, which can improve speed and accuracy of recognition or authorization system, and has diverse applicability. Since conventional works have tried to detect faces based on the whole shape of faces, its detection performance can be degraded by occlusion made with accessories or parts of body. In this paper we propose a method combining local feature descriptors and probability modeling in order to detect partially occluded face effectively. In training stage, we represent an image as a set of local feature descriptors and estimate a statistical model for normal faces. When the test image is given, we find a region that is most similar to face using our face model constructed in training stage. According to experimental results with benchmark data set, we confirmed the effect of proposed method on detecting partially occluded face.
