This research was started to study how the design identity of an overseas fashion house was formed, changed and connected. For the purpose of the study, Saint Laurent House was selected as the subject of the study, because it began as a couture house and launched the $pr\hat{e}t-\grave{a}-porter$ for the first time among the designer brands, and also contributed to the development of modern women's fashion. Literature survey on related books and papers was performed to study the Saint Laurent House. Then, fashion collection photos of the house from 1962 SS to 2014 SS were collected to analyze and compare the features of the designs. The photos were collected from related books, fashion magazines and internet sites. The results are as follows: The features of Yves Saint Laurent's early designs were contemporarily sensational with their couture tradition. His representative designs including Le Smoking, Pea Coat, Loose Fit Blouse, Safari Look, Jumpsuit, Ethnic Look and Art Look became the signature looks of the Saint Laurent House. His designs expressed the liberation of sex, multi-cultural sensitivity and the fusion of art and fashion. His successor, chief designer Tom Ford designed with strong sensitivity of his own. He dealt with Yves Saint Laurent's design themes and signature looks in sensual as well as trendy and sophisticated way. Stefano Pilati showed the Parisienne chic and elegance. He re-made the legacies of Yves Saint Laurent with his own design style using new materials or cutting technique. Hedi Slimane reinterpreted the signature looks of the house with his rock' n roll mood for young, modern women while reflecting the spirit of Yves Saint Laurent's early stage. In conclusion, the design identity of Saint Laurent House is not just a fixed one. By the subsequent chief designers, the signature items and design spirit of Yves Saint Laurent have been succeeded, reintroduced or changed to be trendy and to reflect the designers' design sensitivity. All of these make and maintain the design identity of the fashion house.

Objective : Corpectomy of the first lumbar vertebra (L1) for the management of different L1 pathologies can be performed using either an anterior or posterior approach. The aim of this study was to evaluate the usefulness of a retroperitoneal extrapleural approach through the twelfth rib for performing L1 corpectomy. Methods : Thirty consecutive patients underwent L1 corpectomy between 2010 and 2016. The retroperitoneal extrapleural approach through the 12th rib was used in all cases to perform single-stage anterior L1 corpectomy, reconstruction and anterior instrumentation, except for in two recurrent cases in which posterior fixation was added. Visual analogue scale (VAS) was used for pain intensity measurement and ASIA impairment scale for neurological assessment. The mean follow-up period was 14.5 months. Results : The sample included 18 males and 12 females, and the mean age was 40.3 years. Twenty patients (67%) had sensory or motor deficits before the surgery. The pathologies encountered included traumatic fracture in 12 cases, osteoporotic fracture in four cases, tumor in eight cases and spinal infection in the remaining six cases. The surgeries were performed from the left side, except in two cases. There was significant improvement of back pain and radicular pain as recorded by VAS. One patient exhibited postoperative neurological deterioration due to bone graft dislodgement. All patients with deficits at least partially improved after the surgery. During the follow-up, no hardware failures or losses of correction were detected. Conclusion : The retroperitoneal extrapleural approach through the 12th rib is a feasible approach for L1 corpectomy that can combine adequate decompression of the dural sac with effective biomechanical restoration of the compromised anterior loadbearing column. It is associated with less pulmonary complication, no need for chest tube, no abdominal distention and rapid recovery compared with other approaches.

Today we seem to be flooded with digital culture as the age of information has reached its peak. As fusion culture has been generalized, in which the arts and culture of the East and the West are in harmony, and quality of life has been improved, people are enjoying more abundant cultural benefits than ever. In such a situation, we may lose the origin of our culture and disregard our traditional culture due to the mixture of cultures. In addition, it is necessary at this point to distinguish pure culture from mixed one and to re-illuminate the value of our original culture for the next generation. Therefore, the author took interested in Dongraeyaryu, a large-scale festival in Busan, which has been designated as an important intangible cultural property, and carried out a research for its continuous instruction and activation. among contents such as music, costume, dancing and stage properties that compose intangible cultural property, this study selected costume, which has significant visual effects and large differences in shape between old one and contemporary one, for development. By proposing modernized design of costume preferred by the new generation and in harmony with the masks, this study wished to narrow the generation gap, to direct young people's attention to the learning of tradition and to propose motives that activate the culture of local festival.

Degranulation of the rat peritoneal mast cell induced by intraperitoneal injection of horseradish peroxidase(HRP) was studied using light and electron microscopes. 1. Rat peritoneal mast cells in the Tyrode's buffered salt solution injected control group did not show any particular morphological changes following the specified time course. 2. Under the light microscope, the majority of mast cells observed 10 minutes after HRP injection were nearly the same as those of the control group. However, after 30 minutes, granule densities or staining properties of certain cells began to decrease and these appearances increased gradually until 12 hours after injection, at which time small groups of granules being stained pale-red or pink with toluidine blue were easily identified in the cytoplasm of many cells, and numerous extruded granuleg were scattered around these cells. 3. In the mast cells representing the early stage of degranulation induced by HRP, the electron densities of certain granules decreased as the size enlarged, and perigranular cavities were formed by perigranular membrane expansion. As a result, a thin cytoplasmic septum was formed between the expanded perigranular membrane and the cytoplasmic membrane in the cell periphery, and fusion of the adjacent perigranular membranes was observed in the inner side of the cell. 4. In some mast cells, one or two changes in the peripheral cytoplasmic septum could be seen. One was a focal rupture of the peripheral septum and the other was the formation of a saccule containing one or more vesicles. This saccule was thought to be used for granule-extrusion site and/or material absorptive apparatus judging from the morphological characteristics. 5. As the degranulation proceeded, the granule was extruded from the cell after partial rupture of the peripheral cytoplasmic septum. This phenomenon proceeded to-ward the inner side of the cell through the fused perigranular cavities, and consequently several distinct cavities containing a few unextruded membrane-free granules were formed throughout the cytoplasm after 12 hours. As a rule, the granule-extrusion sites were relatively fewer while the cytoplasmic cavities resulting from degranulation were more numerously observed. Thus, it was thought that the granule-extrusion sites tended to be restricted in the HRP-induced degranulation.

The aim of this study was to test the validity of the hypothesis that the karyotypes of four species of Lepilemuridae were formed spontaneously from their ancestral hybrid karyotype. Hypothetical ancestral haploid Karyotype of Lepilemuridae is composed of 18 autosomes and X chromosomes. Lepilemur mustelinus karyotype has four tandem fused chromosomes and one Robertsonian translocated chromosome pairs. Lepilemur septentrionalis septentrionalis karyotype has only two pairs of translocated chromosomes. We reconstruct and suggest ancestral karyotype of LMU(ancLMU) and LSS(ancLSS), from which all four studied species were derived. Hybrids of ancLMU and ancLSS were formed and produce differently fused equilibrated gametes via circular form arrangement during gametogenesis. Five unit of trivalent homologous chromosome pairs were engaged in a circular form to give new gamete corresponding to the karyotype of L. dorsalis, orientation of one unit of trivalent was inversed in the circle to gave new gamete corresponding to the karyotype of L. leucopus. Seven homologous chromosome pairs were engaged in circular form to give haploid karyotype of Lepilemur ruficaudatus. Only one homologous chromosome pair is dissociated and the other chromosome pairs rearranged in the circle to form haploid karyotype of Lepilemur edwardsi. The new gametes could be produced from these circular forms. When the new gamete fertilized with the same type of gamete, The new homozygote is produced as existing L. dorsalis, L. leucopus, L. edwardsi and L. ruficaudatus. These results support the theory that new species could be formed in hybrid population through activated chromosome fusion, chromosome rearrangement in circular from at zygotene stage and production of equilibrated gametes to form homozygote new species.

Purpose: In the early stage of using PET/CT, it was used to damper revision but recently shows that CT with MDCT is commonly used and works well for an anatomical diagnosis. This hospital makes the accuracy and convenience more higher in the diagnosis and evaluate of coronary heart disease through concurrently running myocardial perfusion SPECT examination, myocardial PET examination with FDG, and CT coronary artery CT angiography(coronary CTA) used PET/CT with 64-slice. This report shows protocol and image based on results from about 400 coronary heart disease examinations since having 64 channels PET/CT in July 2007. Materials and Methods: An Equipment for this examination is 64-slice CT and Discovery VCT (DVCT) that is consisted of PET with BGO ($Bi_4Ge_3O_{12}$) scintillation crystal by GE health care. First myocardial perfusion SPECT with pharmacologic stress test to reduce waiting time of a patient and get a quick diagnosis and evaluation, and right after it, myocardial FDG PET examination and coronary CTA run without a break. One-stop evaluation protocol of ischemic heart disease is as follows. 1)Myocardial perfusion SPECT with pharmacologic stress: A patient is injected with $^{99m}Tc$-MIBI 10 mCi and does not have any fatty food for myocardial PET examination and drink natural water with ursodeoxcholic acid 100 mg and we get SPECT image in an hour. 2)Myocardial FDG PET: To reduce blood fatty content and to increase uptake of FDG, we used creative oral glucose load using insulin and Acipimox to according to blood acid content. A patient is injected with $^{18}F$-FDG 5 mCi for reduction of his radiation exposure and we get a gated image an hour later and get delay image when we need. 3) Coronary CTA: The most important point is to control heart rate and to get cooperation of patient's breath. In order to reduce a heart rate of him or her below 65 beats, let him or her take beta blocker 50 mg ~ 200 mg after a consultation with a doctor about it and have breath-practices then have the examination. Right before the examination, we spray isosorbide dinitrate 3 to 5 times to lower tension of bessel wall and to extension a blood wall of a patient. It makes to get better the shape of an anatomy. At filming, a patient is injected CT contrast with high pressure and have enough practices before the examination in order to have no problem. For reduction of his radiation exposure, we have to do ECG-triggered X-ray tube modulation exposure. Results: We evaluate coronary artery stenosis through coronary CTA and study correlation (culprit vessel check) of a decline between stenosis and perfusion from the myocardial perfusion SPECT with pharmacologic stress, coronary CTA, and can check viability of infarction or hibernating myocardium by FDG PET. Conclusion: The examination makes us to set up a direction of remedy (drug treatment, PCI, CABG) because we can estimate of effect from remedy, lesion site and severity. In addition, we have an advantage that it takes just 3 hours and one-stop in that all of process of examinations run in succession and at the same time. Therefore it shows that the method is useful in one stop evaluation of ischemic heart disease.

Today, every culture has taken on the compromise form by means of the cultural difference, variety, and pluralism according to the internationalization and the advance so that it has been developed toward the half-blooded and multilayered the aspect. In accordance with this current of the times, this thesis observed the feminism found in the multiculturism of the end of the 20th century, the third world, and technology with the side of the tendency of modern fashion, considered the hybride phenomenon which is pulling down the wall between culture and genre due to the social diversification. and predicted the fashion trend do 21st century serf on it. Multiculturism is the movement that began to arise in the academic world of America and the literary world form the close of 1980's in accepting the variety of culture and regarding the culture with the more balanced and wide view and just as it is, it means the attitude of accepting one or more cultures of variely and the position of taking interest in the culture of minority race not the culture of a governing race. It is the fashion of feminism adapts dualism like unisex, androgynous look, etc of bisexual lendency in the 1980's, it shows new style with crossover of liberal sense because there is not the difference of sex in fashion. The eco-feminism pursues the natural sexuality not being instrumental and dismantling and expressed it in the Gender expression of an integrated human being. The trend of ethnic fashion in the close of 20th century is that the element of hippie is working so strongly. By adding embroidery of Oriental style, accessories of Indian style, feathers, beads, a hempen hood to the ethnic costumes of Asia and Latin, is shows the figure of ethnic hippie. As the cycler fashion is the future clothes through technology of computer, it uses a cool glass material bringing up the image of a spacesuit in order to expresses cyber image through artificial color combination of sheen colors, Though this techno-color fashion has established the fresh stimulation and the innovative aspect with ultramodern materials and image of futurism, it transmits a hope of estranged people and the natural elements. Hybride means a cross and mixture of animal and plant in Korean and is also called fusion. The phenomenon of hybrid predicts to comes the period of a cross and variation because something completely new comes into the world by contamination, mixture and compromise through meeting something different each other and it has on advantage of developing something existing to one more stage. It is prospected that in the society of 21st century, the borderline of traditional gender will be disappeared, variety and individuality will determine the individual behavior, and the masculine value will be substituted by feminine value. In the society giving priority to feminine value, a fashion stuck closely to women is what must reflect lives of woman under the proposition of woman's beauty, being on original function. So, it is considered that a fashion with added convenience and practicality having the function which is easy to put on, comfortable to act, able to express solves so much, and able to show various appearances according to T.P.O will get into the spotlight.

The objectives of the present study were to initiate cloning of Korean native goat by somatic cell nuclear transfer (NT) and to examine whether unovulated (follicular) oocytes can support the same developmental ability of NT embryos as ovulated (oviductal) oocytes after hCG injection in stimulated cycles of the goat. The in vivo-matured and immature oocytes were collected from the oviducts and follicles of superovulated does, respectively, and the immature oocytes were maturated in vitro. Ear skin fibroblasts derived from a 3-yr-old female Korean native goat were used as the donors of nuclei or karyoplasts. Following fusion, activation and in vitro culture to a 2- to 4-cell stage, 49 in vitro-derived and 105 in vivo-derived embryos were transferred to 6 and 17 recipient does, respectively. One doe and three does of the respective groups were identified as pregnant by ultrasonography on day 30 after embryo transfer. However, only one doe, which had received in vivo-derived embryos, delivered a normal female kid of 1.9 kg on d 149. The cloned kid gained more weight than her age-matched females as much as 87% during the first 4 mo after birth (17.7 vs. $9.4{\pm}0.8$ kg) and reached puberty at 6-mo age a few months earlier than normal female does. The telomere length of the kid, which was similar to that of the donor fibroblast at 2-mo age, decreased 8% between 2- and 7-mo ages. Moreover, at 7-mo age, she had 21% shorter telomere than her age-matched goats. To our knowledge, this is the first case in which a cloned animal born with a normal weight exhibited accelerated growth and development. The unusually rapid growth and development of the cloned goat may have resulted from SCNT-associated epigenetic reprogramming involving telomere shortening.

Co-ordinate growth of the brain and skull is achieved through a series of tissue interactions between the developing brain, the growing bones of the skull and the sutures that unite the bones. Craniosynostosis, the premature fusion of cranial sutures, presumably involves disturbance of these interactions. Bmp2, one of bone morphogenetic proteins (Bmps), is involved in the regulation of the shapes of individual bones and the relative proportions of the skeleton. Mutations in the homeobox gene Msx2, known as a downstream gene of Bmp, cause Boston-type human craniosynostosis. The phenotype of Dlx5 homozygote mutant mouse presents craniofacial abnormalities including a delayed ossification of calvarial bone. These facts suggest important roles of Bmp2, Msx2 and Dlx5 genes in the cranial bone growth and suture morphogenesis. To elucidate the function of these molecules in the early morphogenesis of mouse cranial sutures, we first analyzed by in situ hybridization the expression of Bmp2(E15-18), Msx2 and Dlx5 genes in the developing sagittal suture of calvaria during the embryonic stage. Bmp2 mRNA was intensely expressed in the osteogenic fronts and also at the low level in the periosteum of parietal bones during embryonic stage, Msx2 mRNA was intensely expressed in the sutural mesenchyme and mildly expressed in the dura mater during the embryonic stage. Dlx5 mRNA was intensely expressed osteogenic fronts and parietal bones. To further examine the role of Bmp signaling in cranial suture, we did in vitro experiments in E15.5 mouse calvarial explants. Interestingly, implantation of Bmp2-soaked beads onto the osteogenic fronts after 48 hours organ culture resulted in the increase of the tissue thickness and cell number around Bmp2 beads, compared to BSA control beads. In addition Bmp2 induced etopic expressions of Msx2 and Dlx5 genes. On the other hand, overexpression of FGF2 did not induce the expression of Msx2 and Dlx5. Taken together, these data indicate that Bmp2 signaling molecule has a important role in regulating the cranial bone growth and early morphogenesis of cranial suture. We also suggest that Bmp signaling is involved in all the stages of osteogenesis of cranial bones and the maintenance of cranial suture by regulating Msx2 and Dlx5 genes, and that Msx2 and Dlx5 genes are specific transcription factors of Bmp signaling pathway.

In this study, we sought to develop an effective cloning system by which human cytochrome $b_5$ (cyt $b_5$) is introduced and expressed in zebrafish. First, the 414 bp human cyt $b_5$ gene was amplified from RNA extracts of HeLa cells using RT-PCR, and the amplicon was subsequently sequenced to confirm that it was intact. Next, cyt $b_5$ was cloned into the pEGFP-N3 vector, which also encodes a fluorescent gene. One-cell stage zebrafish embryos were microinjected with the recombinant vector containing the cyt $b_5$ gene. Fluorescence microscopy confirmed high expression of the fluorescent gene in the injected fry compared to the non-fluorescent control fry. Finally, we extracted RNA from the injected fry and performed RT-PCR to determine whether the human cyt $b_5$ gene is expressed in the transgenic zebrafish. Sequencing analysis further confirmed that the cloned human cyt $b_5$ gene was intact. The transgenic zebrafish model produced in this study will be a useful tool to study therapeutic approaches to cure various diseases related to the deficiency of functional human cyt $b_5$ as well as tools for cloning useful genes in fish.
