Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

In order to explore the detailed distribution of land snails inhabitated in Heongseong, this study was conducted for 2 years (from March 20, 1992 to March 20, 1994) for four optional areas. Total appearances of species were 3 order, 1 Families, 17 Genera, 22 species and total individuals were 3,009. the dominant species were Chamalycaeus cyclophoroides and Diplommatina (Sinica) paxillus. The stati of land snails on size were that there were, in Minute species, Carychium pessinum with 1.5mm shell height and 0.8mm shell diameter, in macro species Acusta despecta sieboldiana, Koreanohadra Kurodana, Aegista (Plectotropis) diversa with 11-21mm sell height, 20-28mm shell diameter. The height and diameter variation of Aegista (Plectoropis) diversa were bigger than anyone else. Also, Numbers of spiral were four to 10, and body colors were mainly white or brown. In terms of inhabitation area, data were gathered more than 14 areas. Among them, species which were inhabitated in the fallen leaves were shown 31.8%, 9-15.9% in stone wall, garden and farming field. Especially Cionella lubrica being known endemic species of Ulung Island was confirmed in Hoengseong.

Pelvic bone is the major bone which has the quite different features between male and female. And these features are well described in almost all gross anatomy textbooks. The parameters which are used to sex determination are related with those of obstetrics. To suggest the most significant parameters for sex discrimination with the bones, we have selected the frequently mentioned 21 metric fields of non-pathologic Korean pelvic bones, whose sexes were already confirmed (M:40, F:19). For easuring these metric parameters, the statistic procedures (descriptive statistics and discriminant analysis, group analysis) were performed(SAS PC version 6.11). The parameters showing more than 80% of discriminating probability are the acetabular length(Martin No. 22) and the pubic angle (Martin No. 16). The parameters showing more than 75% of discriminating probability are the transverse diameters of pelvic outlet (Martin No.27), the breadth of greater sciatic notch, the ischial length (Martin No. 15a), the pelvic breadth (Martin No. 2), the obturator foramen long length (Martin No. 20), the obturator foramen short length (Martin No. 20), and the pelvic height (Martin No.1). All the metric parameters, it could be categorized into 5 groups.

Nowaday, Advanced technology has been applied to organic destruction technologies that are alternatives to incineration. Plasma, photolysis, and Photocatalytic oxidation processes are an emerging advanced technologies for the abatement of volatile organic compounds(VOCs) in atmospheric pressure air streams, so we has been used these technologies for destruction of VOCs. TCE, Benzene, Toluene, and Xylene were selected as objective materials. We have been studied each process and found many types of reaction parameters which effect on treatment efficiency. So combination processes, which are plasma-photocatalytic oxidation process and photolysis-photocatalytic oxidation process, have been used to increase destruction efficiency. Analysis of above materials and byproducts was carried out by GC-FID.

Recently, a Geographic Information System (GIS), which stores a large volume of graphical data into a computer system and manages them efficiently according to user's needs, is widely used. However, since various graphics data formats are now used in geographical information systems and DXF (Data eXchange Format) is used for national topographical maps in Korea, it is necessary to develop a DXF file converter that converts a DXF file into another data file to increase the usage of DXF files. In this paper, we design and implement a DXF converter which convets a DXF file into a PostScript file since the latter is one of the most powerful graphics formats and can be used for various printers directly. It consists of the file manipulation module, the DXF file manipulation module, and PostScript file generation module. In order to develop the DXF converter, we first analyze each of the file formats (i.e., DXF and PostScript formats) and then implement and test the three modules. Finally, we develop the complete DXF file converter by combining the three modules.

The results of radiographic study of healing of fractured mandible are often inconsistent with clinical evaluation of bone healing pattern of it. In addition, there is inconsistency between radiographic studies. We think if such inconsistency is resolved, clinical assessment combined with radiologic evidence can be used to guide to more accurate clinical management. The purpose of this study is to evaluate radiological healing pattern of mandible, and to apply its result to clinical use. Panoramic view was used to analyze the change of radiographic finding in 35 patients (27 male, 8 female, ranging 17 to 53 years old) treated for mandibular fracture at the department of oral & maxillofacial surgery, SNUH in the period 1991 to 1998, Patients are all treated by rigid internal fixation using monocortical miniplate. Within 9 weeks, no change is observed at fracture site. Osteogenic change is observed at various time interval (3 to 21 weeks). We have found radiographic change of healing is observed 4 to 6 weeks later to clinical healing, According to this result, we recommend radiographic follow-up at 4 week, 10 week, 10 month.

융비술시 실리콘 고무는 다루기 쉽고 조직 반응이 적어 현대 많이 돌출의 합병증이 생길 수 있다. 저자등은 이러한 실리콘의 단점을 보완할 수 있는 goretex를 사용하여 융비술을 시행하고 비첨에 대해서 자가연골을 이식하여 만족할 만한 결과를 얻었기에 goretex가 안면부 연조직의 증강을 위한 이식재료로 적합하다고 생각되어 문헌고찰과 함께 보고하는 바이다. Many different materials have been used to provide augmentation of the nasal dorsum. this include both autogenous and homogenous materials,as well as allografts. Silicone among the artificial materials has been most widely used. The silicone has some advantages and disadvantages. Goretex(expanded polytetra-fluoroethylene) which has widely used in vascular surgery and abdominal surgery can be used for facial soft tissue augmentation. The author presemts 2 cases of nasal augmentaion using goretex with literature review.
