Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Art and science to determine the treatment objectives, specifically, the desired soft tissue changes are firstly established by using the clinician's “esthetic sense” of the facial beauty and proportion aided to a few cephalometric guidelines. In this sense, the dependence on the clinician's “esthetic eye” by Dr. Bell is more important in analyzing the facial proportion than the satisfaction of rigid cephalometric norms. The purpose of this article was to elucidate the indication for simultaneous surgical repositioning of the maxilla, mandible, and chin, and to describe the clinical cephalometric analysis for orthognathic surgery. Representative 6 case reports were presented and discussed to illustrate the esthetic, orthodontic, and surgical treatment objectives with long-term follow-up.

This is a retrospective study of 31 patients, who were diagnosed as bilateral TMJ internal derangement in consequence of magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) at Department of Dentistry, Ajou University Hospital, and who were compared clinical findings with radiological findings. The results obtained were as follows. 1. The average of the patients of bilateral TMJ internal derangement was 27.3 years with a range from 12 to 74 years, and 93.6% of the patients were youger than 40 years of age. The male-female ratio was 1 : 6.8, and the females of 20∼29 years were most common in 35.5%. 2. In the patients of bilateral TMJ internal derangement, the patients who complained clinical symptoms bilaterally were 38.7% and the patients who complanined clinical symptoms untilaterally were 61.3%. 3. The most common disc position of bilateral TMJ internal derangement was anterior disc displacement without reduction on both sides in 38.7%. The most common disc configuration of bilateral TMJ internal derangement was biconcave on both sides and amorphous on both sides in closed mouth, and was amorphous on both sides in open mouth. 4. In the patients of bilateral TMJ internal derangement, the joints which really showed clinical symptoms were most common in anterior displacement without reduction of 48.9%.

The esthetics of chin contour is very important in facial deformities, and the quantity of soft tissue overlying the symphysis can be helpful to the correct diagnosis and surgical treatment for optimal facial harmony. The objectives of this study is to measure the different thicknesses of skeletal and soft tissues of chin on lateral cephalometric radiographs, to obtain the mean values of normal Korean adults, and to investigate the relative proportions of skeletal and soft tissues of chin. The results were as follows ; 1. In normal Korean adults, the relative proportions of the distances of soft tissue toward skeletal tissue were 1.5 in B point and 0.95 in Pg, and there were significant difference between male and female in the relative proportion of Pg (p<0.05). The relative proportion of the distances of vertical soft tissue toward horizontal soft tissue of Me was 1.91, and there were not significant difference between male and female. 2. In normal Korean adults, the distances of skeletal and soft tissues of chin showed no correlation, but the distances of vertical and horizontal soft tissues of Me showed high correlation (p<0.01). 3. In normal Korean adults, the correlations among the distances of each skeletal and soft tissues of chin were significantly high in both of male and female (p<0.01). Among the relative proportions of the distances of skeletal and soft tissues, the correlations of the proportions of B point and Mp and the proportions of Mp and Pg were significantly high (p<0.01).

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

Signal distortion due to the path loss, shadow, and multi-path fading is very serious in radio channel. In this paper, we propose CDMA-OFDM cooperative communication system based on DFP(Decode and Forward Protocol) to overcome these phenomena using spread spectrum technique, orthogonal sub-carrier, and the space diversity. We simulated proposed system under Rayleigh flat fading channel environment. A variety of simulation results reveal the cooperation can provide performance gain of up to 12 ㏈ over direct communications in ideal inter-user case at BER of 10?³. And we can also confirm variation of diversity effect as channel environment changes.
