There have been several reports that nasal bone fractures are inadequately managed. They are probably due to poor understanding of the pathophysiology of nasal bone fracture and absence of the accurate diagnostic method. And there has been little adequate comprehensive classification of nasal bone fracture and nasal septal fracture. We examed 132 patients sustaining nasal bone fracture using computerized tomography. Fracture line, deviation, depression, associated skeletal deformities and the nasal septum were clearly identified. We compared our results with Murray & Maran's classification of nasal bone fracture. We found that they revealed almost same results and computerized tomography was good method for diagnosis of nasal septal fracture. The computerized tomography will be helpful for accurate diagnosis and preperative planning of the correction of nasal bone and septal fracture.

There have been increasing interests of diabetes in the realm of plastic surgery due to problems like foot ulcer as a complication, delayed wound healing or higher failure rates of flap surgery. Main pathology in diabetes is microvascular compromise as well as metabolic derangements. The disturbance in microvascular circulation results in ischemic environments in the body and acts as a main factor that determines the limit of reconstructive or aesthetic plastic surgery. A useful method to overcome such problems is the use of hyperbaric oxygen therapy, which is known to be effective in the treatment of ischemic skin ulcer or osteoradionecrosis. However, there have been few studies on the survival of diabetic random skin flap or the effects of hyperbaric oxygenation directed to increase survival of such flap. In our study, we supposed that the survival of diabetic random skin flap was diminished owing to compromised microvascular pathology and blood rheology, and metabolic derangements, so we hypothesized that hyperbaric oxygen therapy has both reversible and irreversible effects on the survival of ischemic random skin flap in Streptozotocin-induced diabetic rats. Increase of local transcutaneous oxygen concentration, O₂ affinity in blood and dysmorphogenesis of red blood cells are reversible and relatively short-term effects and promotion of neoangiogenesis is irreversible or long-term effects. We intended to confirm that hyperbaric rats and to compare the effects between preoperative and postoperative hyperbaric oxygenation on the survival of such flap. And we expect the additional effects of hyperbaric oxygenation on metabolism in diabetic rat, such as lowering the blood glucose level and solving the arrested weight gain. We divided Streptozotocin-induced diabetic rats into three groups: the first was non-treatment diabetic group, the second was preoperative hyperbaric oxygen treated diabetic group(100% O₂, 2 atm, 90min, 15sessions, twice a day), and the third was postoperative hyperbaric oxygen treated group(100% O₂, 2atm, 90min, 15sessions, twice a day). After elevation of random skin flap on dorsum of diabetic rats, we evaluated the extent of flap survival by measuring the necrotic areas at 3rd, 7th, 10th, and 13th postoperative days. At that time, we intended to evaluate both effects on flap survival by preoperative and postoperative hyperbaric oxygen therapy. As a result, flap survival of non-treated diabetic group was 41% at 13th postoperative days. In diabetic groups with preoperative and postoperative hyperbaric oxygen therapy, flap survival were increased to 64.6% and 62.4% respectively. Diabetic groups with hyperbaric oxygen therapy have a tendency of meaningful decrement in blood glucose level. However, there were no meaningful differences between preoperative and postoperative hyperbaric oxygen therapy. Hyperbaric oxygen therapy has no effective correlations with body weight changes. We conclude that hyperbaric oxygen therapy has some useful effects on the survival of diabetic random skin flap.

The morphological analysis of wear particle is a very effective means for machine condition monitoring and fault diagnosis. In order to describe morphology of various wear particle, the wear test was carried out under friction experimental conditions. And fractal descriptors was applied to boundary and surface of wear particle with image processing. These descriptors to analyze shape and surface of wear particle are shape fractal dimension and surface fractal dimension. The boundary fractal dimension can be derived from the boundary profile and surface fractal dimension can be determined by sum of intensity difference of surface pixel. The morphology of wear particles can be effectively obtained by two fractal parameter.

Although many authors have been trying to reconstruct the auricles with various methods, there leaves much to be desired owing to the complex morphology of the ear. Extreme skin shortage for full corverage of the sculpted costal cartilages, poor projection of helical rim, in-adequate convolutions, and the maintenance of the auriculocephalic sulcus are frequent challenging problems,in total auricular reconstruction. The goals of auriclar reconstruction are to make the reconstructed ear similar to normal side, to make it stable and durable, and to locate it in proper position. To obtain the sufficient, thin, pliable, and well vasculized skin, the authors used tissue expansion at the first stage of the auricle reconstruction in congenital microtia, post-traumatic deformities of auricle, post-meatoplasty in congenital microtia, and lower set ear lobule. After the insertion of tissue expander, the expander was aggressively inflated as soon as possible to obtain more pliable tissue and thinner capsule before the formation of the thick capsule. And it was inflated to the volume of 70-80cc to alleviate the expected contracture of expanded pocket. The expanded skin provided sufficient, thin, pliable, and well vasculrized skin for easy draping, better contouring, and accurate positioning of reconstructed ear. At the stage of implantation of rib cartilage, the modified method of Burt Brent in the autogenous rib cartilage carving was used, and continuos negative suction drainage with Hemovac was used to maximize the coaptation of the skin flap with the implanted cartilage, which was always added to additional crescent shaped cartilage under the base bloc, to exaggerate the helical projection. And at the stage of auricle elevation, posterior scalp advancement flap into the base of elevated ear was used to provide the stability after elevation and to decrease the size of FTSG. From September, 1985 to March, 1994, 27 microtia patients were operated on after tissue expansion at the age of 9-14 years old and followed up for 3 to 9 years. Through the experiences with those patients we wish to recommend procedure for reconstruction of auricle of congenital microtia, post-traumatic ear deformity, post-meatoplasty in congenital microtia, and lower set ear lobule.

중세 동업조합의 총회(Morgensprache) : 북독일 도시의 사례를 중심으로 The Case of Northern German Cities

박흥식 한국서양사학회 2000 西洋史論 Vol.67 No.1

Recent studies on guilds in the medieval period have focused on the types of their association, the result of which have paid little attention to how they managed to lead communal lives of their own. This paper examines the organization and communal nature of the guild based on general assembly of its members (Morgensprache) with a view of filling the lacunae of recent studies. This study will show the character of autonomous community achieved by its members by examining vividly the real picture of self-governance of the association through the openings and proceedings of Morgensprache. In addition, the character will be shown by examining the limits of authority of the city-lord and the municipal council in the matter of jurisdiction and judicial power of Morgensprache. In this paper I use the statues of northern German cities, Lu¨neburg and Goslar, as a concrete case studies of Morgensprache of merchant and craft guilds. With the help of primary sources I can find the following facts: members of the guilds organized their associations for meeting their needs and autonomously solving the problems in lives. Morgensprache was the center of their autonomous communal lives. Morgensprache was the place where debated urgent and annually repeated agenda. It also punished members violating the statues and had judicial powers not to be exercised by outside members. The jurisdiction of Morgensprache was essential for solving impending problems of the guild. This jurisdiction made it possible for the guild to regulate the choice of occupation and most of every lives of members. The guild imposed mostly economic regulation on its members when they violated 'communal norms' written in the statutes. It also employed the coercive expulsion from the community in order to maintain the discipline and cohesion of the organization. In general, the basic significance of Morgensparche can be found in the attempt to solidify the communal cohesion of guild members by pledging an oath, religious ceremony, and banquet including communal dinner rather than counsels and judicial courts. The guild could achieve the common interests of its members based on the collective ceremony and experiences, and the feeling of solidarity resulted from the former two. The guild enjoyed somewhat an autonomy regardless of its size and number of its members, but it remained a subordinate organization of the city. The organization of the guild and lives of its members in fact were regulated by the council based on the fact that all citizens and heads of the guilds as well as its members had an obligation of annual oath and the surveillance function of the council on the guild, which was especially manifest in Lu¨neburg.(Seoul National University)
