Hyang-Yack-Ku-Keup-Bang(鄕藥救急方) is our own, medical work written about the middle of the time of Korea Dynasty. I restored and researched this book because it needed to be illuminated about its medico-historic value and then I came to some conclusions as follows. 1. Hyang-Yack-Ku-Keup-Bang was published in Dae-jang-do-kam(大藏都監) of Kanghaw island(江華島) about the middle of Korea Dynasty. Choi Ja-ha(崔自河) republished it on original publication ground in Euiheung(義興) of Kyungsang-Province(慶尙道) in July, Taejong's(太宗) 17th year of Chosen Dynasty (A.D.1417) and this book was published again in Chungcheng Province(忠淸道) in Sejong's(世宗) 9th year(A.D.1427). The book published in Taejong's days was in the possession of books department of Kung-nae-cheng(宮內廳) in Japan and was the oldest medical book of existing ones. 2. Bang-Jung-Hyang-Yack-Mock-Cho-Bu(方中鄕藥目草部) of this book was originally intended to be adjusted in each division with the title of Bang-Jung-Hyang-Yack-Mock(方中鄕藥目). But Herb part(草部) only followed editing progress of Jeung-Lew-Bon-Cho(證類本草), the rest is not divided into each part and is together arranged at the below of Herb part with the title of Bang-Jung-Hyang-Yack-Mock-Cho-Bu. The Korean inscriptions on some drugstuffs in this book are different between Native Name(鄕名) of three volumes of provisions and general-spoken(俗云) of Bang-Jung-Hyang-Yack-Mock-Cho-Bu. In this, it is estimated that the publishing time and editor of tile volume of provisions and Bang-Jung-Hyang-Yack-Mock-Cho-Bu are different. I think Choi Ja-ha compiled this behind three volumes of provisions when he published. 3. This book picked some prescriptions which consisted of obtainable drugs with ease in Korea in the books of Chell-Keum-Yo-Bang(千金要方), Oi-Dae-Bi-Yo(外臺秘要), Tae-Peong-Sung-Hye-Bang(太平聖惠方), Ju-Hu-Bang(?後方), Kyung-Hum-Yang- Bang(經驗良方) Bo-Je-Bon-Sa-Bang(普濟本事方) Bi-Ye-Baik-Yo-Bang(備預百要方) and so on and got together our own prescriptions. On the whole Bi-Ye-Baik-Yo-Bang was a chief referrence book, On this, other books referred to and corrected. 4. In provisions quoted from Hyang-Yack-Jip-Sung-Bang(鄕藥集成方), there are seven provisions; leg-paralysis part, coughing part, headache part, obstetrics part, etc. don't show in this book. This is why Choi Ja-ha published only certain texts on Dae-jang-do-kam edition his own posession. So we can think the existing edition has a little misses compared with original edition. 5. This book recorded only names of drugstuffs in animal drug department like fowls, crab, goldbug, earthworm, etc. and didn't tell us ways of taking those. This is effect of Buddhist culture on medicine. This is efforts to practice 'Don't murder';one of Five Prohibition of Buddhism. 6. Beacause this book was published at the time, when our originative medicine would be set forth. This followed the Chinese ways in Theory, Treatment, Prescription and used 'Hyang Yack' in Medication out of theory of Korean medicine, which was a transitional form. So this is all important material which tell us aspects of development of 'Hyang Yack' the middle of Korea Dynasty.and this is also the beginning of originative, medical works like Dong-Eui-Bo-Kam(東醫寶鑑), Dong-Eui-Su-Bo-Won(東醫壽世保元). 7. There are few contents based on 'Byen-Jeung-Lon-Chi(辨證論治)'in this book. So we can see this book is not for doctors who study medical thoughts but for general public who suffer from diseases resulted from war. Because this book was written for a first-aid treatmeant, this is an index of medical service for the people those days. And this is also an useful datum for first-aid medicine or military medicine in these modern days. 8. Nowadays, parts of learned world of Korean medicine disregard essential theories and want to explain Korean medicine only by the theories or the methods of Western medicine. Moreover they don't adopt Chinese and Japanese theorys & thoughts about Oriental medicine in our own style and just view in there level. What was worse, there is a growing tendency for them to indulge in a trimming policy of scholarship and to take others' ideas. I think these trends to ignore our own medical thoughts involving growth of 'Hyang Yack' in the middle of Korea Dynasty, Dong-Eui-Bo-Kam and Dong-Eui-Su-Se-Bo-Won. So we, as researchers of Korean medicine, must get out of this tendency, and take over brilliant tradition and try to develop originative Korean medicine.

Christian Cay Lorenz Hirschfeld is often regarded as 'a father of landscape garden art.' He was an aesthetics professor and garden theoretician in the $18^{th}$ century. He put forth the most comprehensive garden theory book in five volumes between 1779 and 1785. His book, Theorie der Gartenkunst, was translated and widely circulated in his contemporary. The book, which dealt with diverse aspects of garden art such as history, design, material, and type, urged to promote the prevalence of landscape garden in European continents as well as in Germany. However, there have scarcely been discourses in the Hirschfeld's garden theory. This essay aims to review Hirschfeld's garden thoughts in his book critically and to reinterpret some issues in the contemporary landscape theory and practice. Hirschfeldian theory was the product of $18^{th}$ century German Enlightenment and romanticism. At that time, Nature was regarded as divine realm. There was a German affinity with natural world. The spread of reading culture and the fashion of travel literature were another background of the success of his garden literature. Several issues in Hirschfeld garden theory will discussed here. First, privileging garden art was the most significant contribution in his theory. He emphasized that garden art was the most advanced art form among all art genres. Second, garden art was grounded on the mimesis of nature. The ambiguous relationship between nature and art still existed in garden making. However, garden art can be flourished when utilizing the potency of nature in itself. Third, there was the association between the image and the idea in experiencing the garden. Some garden scenes stimulated the related emotional responses such as cheerful and merry, softly melancholic, romantic, solemn etc. Fourth, the movement was the essential aspect of garden art. Motion and emotion are come together in garden experience. To represent the landscape garden style in suitable way, the sketch or image seems to be preferable than the plans and views. Finally, garden art was composing of not only the physical space but also the spirit of place. He maintained the garden art as hortus moralis should be a social metaphor. Hirschfeldian garden theory has often been criticized as the lack of practical power and the old fashioned idea. However, his theory influenced on formulating the idea of public park in $19^{th}$ century. Moreover, there are still some visionary aspects of his theory such as the reevaluation of garden art, the emphasis of locality and the introduction of Mittelweg idea. Recently, gardening culture are prevalent in various realms of art and life. Hirschfeld's garden theory as humanistic landscape theory can provide us some insights in the contemporary practices.

From the ancient times, incense was used for various usages including a means of beauty expression with flavor, a medicine for disease treatment and a device for religious event or ritual. The period of T'ang was the times when cultural and material exchanges with foreign countries were very actively made under the political openness of the Chinese nation. Here the exchanges were made mainly through inland trade, called Silk Road(絲綢之路) and marine trade routes, Incense Road(香料之路). This indicates that incense was one of the main items actively traded at that time. In addition, literatures of the T'ang period show that in the Chinese nation, a wide range of classes from the imperial family to the public used incense for many different purposes. This suggests that the culture of incense was deeply prevailed and very socially significant in T'ang. This study investigated social factors that promoted the incense culture of T'ang and the applications and types of incense widely used in the period of T'ang. First, influential religions and the openness of sex culture were main social factors that made incense culture flourish in the period of T'ang. Above all, two main religions of the Chinese nation, Buddhism and Taoism became secularized under political protection by the imperial family. As Buddhism was popularized, the Buddhist ritual of incense burning made a contribution to making public incense culture. Providing its doctrines of eternal youth and eternal life, Taoism necessarily used incense to form a Taoistic climate. The flourishment of the foresaid religion in T'ang added more fuel to that of incense culture in the Chinese nation. The openness of sex culture brought about the Inauguration of the empress, improvement in female position and free relationships between man and woman. It was accelerated by sexology as a method of eternal youth provided by Taoism. The opened culture also developed the culture of kibang where female entertainers called kinyeo consumed lots of incense for decoration and sexual desire stimulation. These open climates of T'ang society made a great contribution to making incense culture, especially for decoration, prevailed throughout the Chinese nation. Second, types of incense prevailed and widely used in the period of T'ang included olive incense, germander(廣藿香), olibnum(乳香), myrrh Resinoid(沒藥), jia Xiang(甲香), clove(丁香) and Shen xian(沈香), all of which were imported from foreign nations and had various applications. Specifically, olive incense, germander(廣藿香), olibnum(乳香) and myrrh Resinoid(沒藥) were used for religious purposes while, jia Xiang(甲香), clove(丁香) and Shen xian(沈香) for the purposes of religion and decoration. In conclusion, a number of social factors including political, religious and medical purposes and the openness of sex culture set fundamentals on which the culture of incense was extensively developed and established as a social trend in T'ang. In the Chinese nation, incense culture was not just an option for taste, but a part of life style social members needed to know. People of T'ang not only enjoyed incense mainly for purposes of religion, pleasure and make-up, but also had the wisdom to know various effects of incense, curiosity about such new things and the will to imitate and pursue alien culture, resultantly flourishing incense culture. Thus the culture of incense represented many social aspects of T'ang.

Although a variety of synthetic vascular grafts are available in modern vascular surgery, no ideal prosthesis ha,4 yet been developed. Small-caliber vascular grafts with low flow, as used in the lower extremity, continue to become thrombosed at unacceptable rates. We have developed and evaluated the new antithrombogenic blood contacting surfaces in canine model. Material and Method: Two now antithrombogenic blood contacting surfaces(Polyvinylalcohol -Polyurethane(PVA-PU) blend and natural Graphite-polyurethane(G-PU) blend) have been developed and evaluated in canine model, using vascular grafts and patches. The luminal surfaces of the test vascular grafts(5 mm ID) were fabricated by dipping a glass rod in PVA-PU blend solution(50 % PVA) using phase separation method. Mongrel dogs of either sex weighing 18-22 kg were anesthetized by endotracheal intubation using halothane and their lungs were ventilated with a volume-cycled ventilator, Maintenance anesthesia with 0.5-1.0% halothane and supplemental oxygen was used. Two pairs were used for comparison in the bilateral femoral arteries for both vascular grafts(PVA-PU vs. PU) and vascular patches(G-PU vs. PU). Bilateral groin incisions were made and the arteries were exposed and clamped. After an excision of 1 cm of the artery between clamps, a grail of 2.5 cm in length was implanted end-to-end using 6-0 polypropylene suture. The vascular patch was implanted as a form of on-lay patch. Animals were sacrificed at 1, 2, 4, 6, 8 and 16 weeks for vascular grafts and 1, 2. 4 and 6 weeks for vascular patches. Result The vascular grafts of PVA-PU blends showed patent lumina in the 2 and 16 weeks animals, while those of PU showed a patent lumen in 2 weeks animal. PVA-PU graft of 16 weeks showed a fairly clean luminal surface. A light microscopic finding of this graft demonstrated good tissue infiltration through porosity, The animals with vascular patches showed patent arteries in both groups except 2 weeks animal. Scanning electron microscopy of the luminal surfaces of G-PU patches in 4 and 6 weeks animals showed endothelial cell covering with microvilli. PU patches showed qualitatively less endothelial cell covering. Conclusion: In conclusion, PVA-PU and G-PU blends can be a promising blood contacting surfaces for application in a synthetic vascualr graft. However, further animal study is needed to determine the real long-term effects of these methods of surface modifications.

The processing management forms of our country's filature factories in 1969 are summarized as follows. (1) About 80％ of total cocoon collection is made within 5 days involving peak day, and 10％ of cocoon collection is finished until 3 days before and after the peak day, (2) About 92％ of alive cocoons transported on unpaved road, and about 40％ of the cocoons purchased by all factories are loaded on trucks from common selling station which is far beyond 40km, therefore a new packing system of alive cocoons to drop the damage of cocoon qualities, should be taken. (3) 22％ of all factories in our. country have only low-temperature cocoon drying machine. Therefore the installment of hot-air cocoon drying machine is required urgently. (4) In view of cocoon qualities in our country, the grouping method of cocoon for reeling. taken by about 50％ of the factories at percent, which classify cocoons for reeling as high group (1,2,3,4 grades) and low group(5,6 grades), will have to be replaced by the method tat classify them high group (1,2 grades) middle group (3,4 grades), low group (5,6 grades). (5) The .ratio of cocoon assorting stood about 10％ in multi-ends reeling, about 15％ in automatic reeling, conclusively, the ratio of cocoon assorting for automatic reeling was higher tan that for multi-ends reeling. One person's ability for a day in cocoon assorting reaches to about 80-100kg. (6) Cocoon cooking condition requires the increase of the cooking time, the pressure and temperature used to be prolonged as much as the qualities of cocoons are material cocoon ior automatic and double cocoon machines are treated uncompletely. (7) Automatic silk reeling is being performed at 1-2$^{\circ}C$ lower in reeling water temperature and operated at about twice velocity. (8) The temperature and humidity of rereeling room stood at 25$^{\circ}C$, 67.2％ R.H and 32.3$^{\circ}C$, 51.9％ R.H of rereeling machine are showed, Average rereeling velocity is 233m/min and large reefs charged for one person are 7.5 reels and form of skein used in all factories is double skein. (9) About 73％ of water sources for filature used under-earth water. About 48％ of all filature factories in our country have not yet water purifying equipments. Installation of the equipment for these factories seems to be urgent, (10) Denier .balance, sizing reel, seriplane, are being used in most factories as self-inspection apparatus. (11) More than 90％ of the factories use the vacum tank in rereeling process and about 20％ of them use it in cocoon cooing process (12) Only 21％ of the factories use chemicals in filature process. About all them use "Seracol 100" in cocoon cooking process and "Seracol 500" in rereeling process, (13) Above survey results explain each all factories show large difference in the processing management. Therefore, it is believed that intercommunication through seminar or technical exchange will contribute to the production evaluation of cocoon in our filature industry.

Recently, Interest to the photoconductor, which is used to flat form X-ray detector such as a-Se, $HgI_2$, PbO, CdTe, $PbI_2$ etc. is increasing. In this study, the film layer by using the photoconductive material with particle sedimentation was fabricated and evaluated. The quantization efficiency of the continuous X-ray with the 70 kVp energy bandwidth was analyzed by using the Monte Carlo simulation. With the results, the thickness of film with 64 % quantization efficiency was 180 ${\mu}m$ which is similar to the efficiency of 500 ${\mu}m$ a-Se film. And $HIg_2$ film has the high quantization efficiency of 74 % on 240 ${\mu}m$ thickness. The electrical characteristics of the 239 ${\mu}m$ $Hgl_2$ films produced by particle sedimentation were shown as very low dark current(under 10 $pA/mm^2$), and high sensitivity(19.8 mC/mR-sec) with 1 $V/{\mu}m$ input voltage. The SNR, which is influence to the contrast of X-ray image, was shown highly as 3,125 in low driving voltage on 0.8 $V/{\mu}m$. With the results of this study, the development of the low-cost, high-performance image detector with film could be possible by replacing the film produced by particle sedimentation instead to a-Se detector.

Background: The aortic arch replacement in an acute aortic dissection is technically demanding procedure that has a lot of postoperative morbidity and high mortality The authors have applied several techniques of aortic arch replacement to overcome the risks of the procedure. Therefore we analysed the results of these techniques. Material and Method: From March of 1996 to July of 2002, we performed 31 cases of the aortic arch replacement in the Stanford type A acute aortic dissection. There were 12 male and 19 female patient's with 59.6$\pm$9.4 years of mean age. Among them 18 cases were treated with the hemiarch replacement and 13 cases with the total arch replacement. We approached the aortic arch through median sternotomy in all but 3 cases of Clamshell incision and applied the deep hypothermic circulatory arrest with retrograde cerebral perfusion. The associated procedures were 2 Bentall's procedures, an axillobifemoral bypass, a femorofemoral bypass and a carotid artery bypass. Result: The postoperative morbidities were 8 acute renal failures, 3 CNS complications, 2 low cardiac output syndromes, 2 malpefusion syndromes, and 2 deep wound infections. There were 4 cases of early hospital mortality which were from an acute renal failure a postoperative bleeding, a low cardiac output syndrome, and a reperfusion syndrome. There were 3 cases of late hospital mortality which were from an acute renal failure, and 2 multiorgan failures. So the total mortality rate was 22.5%. There were 4 cases of late mortality after the discharge, which were form 2 cases of distal anastomotic rupture and 2 cases of intracranial hemorrhage. Conclusion: The hemiarch replacement has relatively shorter operative time and lower hospital mortality but higher late mortality than the total arch replacement. The total arch replacement needs more technically demanding procedure.

Background: Pulmonary hamartomas are the most common form of pulmonary benign tumors, and they occur in approximately $2{\sim}5%$ of all pulmonary neoplasm. However, only a few reports have been published on the clinical characteristics of pulmonary hamartoma in Korea. Material and Method: The charts, X-rays and pathological specimens of 37 pulmonary hamartoma patients who were diagnosed by a pathological examination from January of 2000 to May of 2005 at the Catholic Medical Center were retrospectively reviewed. Result: The peak incidence of the tumor occurred in the seventh decade of life (32.4%), There were 23 men (62.6%) and 14 women (37.8%), with mean age of 55.6 years. Twenty-six patients (70.3%) were asymptomatic and 11 patients (29.7%) had symptoms. A total of 29 tumors (78.4%) were parenchymal, and 8 (21.6%) were endobronchial. Twenty cases (54.1%) were in the right lung and 17 cases (45.9%) were in the left lung. The right lower lobe was most commonly involved. Thirty-two (86.5%) hamartomas were diagnosed by surgical resection, 4 cases (10.8%) were diagnosed by bronchoscopic biopsy and 1 case (2.7%) was diagnosed by a fine needle aspiration biopsy. Thirty-four hamartomas (91.9%) were managed by surgical resection without complication. No recurrence or malignant changes were seen during the follow up period. Conclusion: Pulmonary hamartomas are most common in males during their fifth to seventh decade and they more commonly involve the right lung. No recurrence or malignant changes were seen during the follow up period.

About the phenomenon of being imaged of everything, the scholars of the humanities who had studied on the simple reason structure in a text have been in a big agony how accept it. Especially, semiologists have studied about this for a long time and the points at issues of Saussure, Peirce as well as Umbeto Eco are more outstanding. Being based upon his philosophic interesting from medieval esthetics to modern semiotics, Eco was very concerned about the field of general esthetics and poputar arts like television and cartoons. He connected the mutual open-relations between 'signifier' and 'signified' debated in Semiotics with the open and vague modern arts and regarding it as a deviation from the custom, intensively studied the film-media. Saussure is a representative figure of semiotics and explained Sign and the character of semiotics as the division into two parts such as signifier/ signified, form/ substance, langue/ parole, synchrony/ diachrony. The triadic semiotics (the theory that Sign is composed of the triadic structure like sign, referent and interpretant) of Peirce put the new item- 'interpretant' in sign and referent to connect them and open the possibility to introduce time in to the Sign. In this paper, I try to analyze a cartoon film in the semiotic structure with the systemic, reasonable and logical approach and analysis as as possible. While the images shown through a film were depended on the romantic and impressional judge in the past, due to semiotics, it' s quite possible to correlate the procedure of symbolization to social coherence so that we analyze the incredible power of images to suck audiences with the systemetic Sign. I accept all ot film-images including a cartoon film as not the simple esthetic arts but a social custom and system, want to serve as a aid to properly understand world and humanbeings and prevent the film-image from being mystic. A cartoon and a cartoon film which were begun with the link of a text and an illustration give shape to all of images such as materials, places and even thoughts with a cartoon icon existed in only a cartoon. A cartoon and a cartoon film simply and exquistely conceptualize the complex and vague attribute of an organic creature and extend them infinetly beyond language. However, it can be exploited as a mysticism to temptate the general public and a faking material. In addition to that, it can distort our world-knowledge engaging a political power and the massive power of mass media. In this paper, being based on semiotics to approach a cartoon film in a scientific and organic system, I conclude that a non-linguistic cartoon expression is entangled with the manifold signs and implies the supplementary meanings just like a regular linguistic expression. It remarks that the iconic images of a cartoon film are composed of the social codes and can be analyzed on grounds of a linguistic system.

Microplastics are one of the substances threatening the marine ecosystem. Here, we summarize the status of research on the effect of microplastics on marine life and suggest future research directions. Microplastics are synthetic polymeric compounds smaller than 5 mm and these materials released into the environment are not only physically small but do not decompose over time. Thus, they accumulate extensively on land, from the coast to the sea, and from the surface to the deep sea. Microplastic can be ingested and accumulated in marine life. Furthermore, the elution of chemicals added to plastic represents another risk. Microplastics accumulated in the ocean affect the growth, development, behavior, reproduction, and death of marine life. However, the properties of microplastics vary widely in size, material, shape, and other aspects and toxicity tests conducted on several properties of microplastics cannot represent the hazards of all other microplastics. It is necessary to evaluate the risks according to the types of microplastic, but due to their variety and the lack of uniformity in research results, it is difficult to compare and analyze the results of previous studies. Therefore, it is necessary to derive a standard test method to estimate the biological risk from different types of microplastics. In addition, while most of the previous studies were conducted mostly on spheres for the convenience of the experiments, they do not properly reflect the reality that fibers and fragments are the main forms of microplastics in the marine environment and in fish and shellfish. Furthermore, studies have been conducted on additives and POPs (persistent organic pollutants) in plastics, but little is known about their toxic effects on the body. The effects of microplastics on the marine ecosystems and humans could be identified in more detail if standard testing methods are developed, microplastics in the form of fibers and fragments rather than spheres are tested, and additives and POPs are analyzed. These investigations will allow us to identify the impact of microplastics on marine ecosystems and humans in more detail.
