―The brilliant culture of pottery in our country, the Unglazed― ―earthenware of Silla Age, the Celadon-were of Ko-ryo, and the White― porcelain, Bun-cheong-sa-ki of Lee Dynasty, is recognized for its excellency throughout the whole world. Pottery was produced both as a private ceramic factory of the common people, and as a government ceramic factory that made the supplies for government use. The widespread of use of mass-produced pottery from abroad that was cheap and practical led the government to cease the making of pottery by hand in 1883, and to begin large-scale industrial pottery production, as well as to conduct various studies on methods of producing pottery. Making of Body (clay). The body is the most fundamental part of making pottery, and is divided into unglazed earthenware, earthenware, stoneware, porcelain. And the method of making the body is different according to the kind of ceramic. Most fund amentally, the materials must be easy to find and must have plasticity, hold colour and had sinter well. Furthermore, well kneaded body has an even mixture of colloid of clay and moisture, and when touched, it must leave clear fingerprints without sticking to ones hands. Well kneaded body must age for over a week. During this time, the impurities of body and bacteria get spoiled which supplements the plasticity, and will prevent cracking when formed into pottery. When making a coloured body, the proper quantity of stain must be added to the body. The methods of forming, excepting those of ceramic sculpture, are wheeling, free hand, coiling (Ta-Ryum forming), slabbing, applied moulding of plates and bottles, shaving the shape, and making a handle to stretch the body. In this these, the theory of these methods of forming will be explained, and the actual process of production will be illustrated through pictures.

With increase of traffic accidents, the otologic problems including facial palsy with skull fracture are more concerned. This paper is report our experiences with 16 cases of traumatic facial nerve palsy which have been employed transmastoid supralabyrinthine facial nerve decompression during last four years. The results are as follows: 1. Of the 16 patients, 13 patients(81.3%) were men and 3 patients (18.8%) were women. And sex ratio was 1.4:1 (male predominent). 2. In fracture type, longitudinal fracture was 10 cases (62.5%), transverse fracture was 1 case(6.3%) and mixed fracture was 2 cases(12.5%). 3. Cerebral contusion was combined in 8 cases(50%) and facial bone fracture was combined in 6 cases(37.55). Because of these combined lesions, otologic diagnoses and treatment was delayed. 4. The most common physical finding on clinical examination were a bloody otorrhea(75%) and hearing impairment(75%). 5. In frequency of lesion in facial nerve, tympanic segment(35.7%) was the most common site, followed by geniculate ganglion(14.3%). Suggested mechanisms in facial palsy were nerve compression(57.1%), granulation tissue and congestion. 6. There were improvment of House-Brackmann grades in 13 cases after decompression. 7. Incudostapedial separation was found in 4 cases and incus fracture was found in 2 cases. Hearing improvement was found in 3 cases being ossiculoplasty.

The need for rapid diagnosis and treatment of life-threatening thoracic and intra-abdominal injury result in controversy over the appropriate triage of unconscious blunt trauma patients. To aid in early decisions for these patients, a prospective analysis of 98 patients with glasgow coma scale(GCS) scores≤8 was undertaken. Although intra-thoracic and intra-abdominal injuries were frequently identified based on systolic blood ressure, the use of clinical signs alone resulted in more missed injuries than did using the emergency ultrasonography. In normotensive patients(n=34), intra-thoracic injuries was identified in one patient(2.9%), and intra-abdominal injuries were in 7 patients(20.6%). In shock(systolic blood pressure<90mmHg) Pa-tients(n=64), thoracic injuries and intra-abdominal injuries were diagnosed in 8(12.5%) and 27 patients(42.3%), thoracic and abdominal combined injuries were identified in 11 patients(17.2%). The sensitivity, specificity, and accuracy of emergency ultrasonography were 96.3%, 91.7%, 94.9%. This study suggests that all unconscious trauma patients undergo immediate emergency ultrasonography to prevent missing life-threatening injuries.

Background : Mortality from paraquat intoxication depends upon plasma paraquat concentration. To know the severity of paraquat intoxication is important for directing therapeutic modality and predicting prognosis. Sodium dithionite test for urinary paraquat provides an easy and simple method to determine the severity of paraquat intoxication in emergency department. purpose : To determine whether the result urinary paraquat test by sodium dithionite can predict outcome in patients with paraquat intoxication in emergency department. Subjects : 48 patients(male 31, female 17, mean age 37 years) who had exposure to paraquat and presented within 24 hours after exposure. Result : Thirty five patients were positive in paraquat urine test and thirteen patients were negative. Clinical manifestations were more severe in positive patients than in negatives. Complication was much more in positives than in negatives. 28 of 35 patients(80%) in positives and 2 of 13 patients(15%) in negatives died. Conclusion : Positive test for urinary paraquat is associated with high mortality and morbidity from paraquat intoxication, and qualitative test for urinary paraquat by sodium dithionite is an useful method to determine the severity of paraquat intoxication in emergency department.

Background : Cardiac arrest is a potent stimulus for the release of endogenous catecholamine and high plasma catecholamine concentration has been reported during cardiopulmonary resuscitation(CPR). Few data were present about the clinical effect of high plasma catecholamine and endogenous catecholamine response to exogenous epinephrine administration during CPR. Purpose : This study was designed to evaluate endogenous catecholamine response to cardiac arrest and exogenously administered epinephrine during CPR. Method : In 21 cardiac arrest victims, blood sample for epinephrine and norepinephrine was drawn before and 1 minute after each epinephrine administration during CPR. 1mg of epinephrine was administered immediately after intravenous access and 3 minute interval during CPR. Plasma catecholamines were quantitated by high-performance liquid chromatography. Result : Baseline plasma epinephrine concentraqtion was higher in patients with cardiac arrest than normal controls (985±1627 vs 194±173 pg/ml, p<0.05). Baseline plasma norepinephrine concentration was also elevated in patients with cardiac arrest than normal controls, although statistically insignificnat(1965±4915 vs 360±250 pg/ml). Plasma epinephrine concentration in cardiac arrest patients was significantly elevated after exogenous administration of epinephrine, but its response was blunted after the third does of epinephrine. Plasma norepinephrine concentration in cardiac arrest patients was also elevated, but its response was observed only after the first epinephrine administration. Plasma epinephrine concentration was persistently higher in patients with return of spontaneous circulation (ROSC) than patients without ROSC. there was no significant difference of plasma norepinephrine concentration whether spontaneous circulation was restored or not. Endogenous epinephrine response to exogenous epinephrine was not observed in patients having prolonged arrest time over 20 minutes. Conclusion : Results of this study suggests that significant amount of catecholamine is released by exogenous epinephrine administration in spite of high plasma catecholamine concentration, and degree of endogenous catecholamine response influences resuscitation outcome.

In the guidelines of Advanced Trauma Life Support(ATLS), essential plane roentgenograms (chest AP vIew, cervical spine lateral view and pelvis AP view) are recommanded when primary survey and resuscitation phase are finished in care of multiple injured patients. A prospective study was carried on 376 multiple trauma patients who admitted to Wonju Christian Hospital from July, 1995 to October. We analyzed clinical significance of essential X-ray in multiple trauma patients, and classified the patients by their status of mentality. The one is alert group when their Glasgow Coma Scale(GCS) is over 13 point, the other is disoriented mentality group when their GCS are below 12 point. The alert group was redivided by presence of clnical symptoms and/or signs, and clinical significances of essential X-ray were analyzed. Among the 376 patients, 330 patients are alert group that their GCS score is over 13 point and 46 patients are disoriented group who's GCS were below 12 point. The detection rate of abnormality in essential X-ray is higher in disoriented group than alert group(cervical-spine lateral view : 13.5% vs 3.0% cheat AP view : 0.4%, pelvis AP view : 0%). This study suggests that their are no needs of taking essential X-ray in patients who is alert in mental state and have no clinical symptoms and/or signs.

<B>ABSTRACT</B><P>Halocidin is an antimicrobial peptide found in the tunicate. A series of experiments were previously conducted in an attempt to develop a novel antibiotic derived from halocidin, as the peptide was determined to evidence profound antimicrobial activity against a variety of antibiotic-resistant microbes, with significantly less toxicity to human blood cells. In this study, we assessed the validity of one of the halocidin congeners, called Khal, as a new antibiotic for the treatment of systemic bacterial infections. Our in vitro antimicrobial tests showed that the MICs of Khal against several gram-positive bacteria were below 16 μg/ml in the presence of salt. We also determined that Khal retained sufficient target selectivity to discern microbial and human blood cells and was therefore capable of efficiently killing invading pathogens. Furthermore, Khal caused no aggregation problems upon incubation with human serum and also proved to be resistant to proteolysis by enzymes occurring in human serum. In the following experiments conducted with a mouse model of <I>Listeria monocytogenes</I> infection, we demonstrated that a single intravenous inoculation with Khal resulted in significant therapeutic effects on the survival of mice. In addition, our bacterial-enumeration analysis showed that after <I>Listeria</I> infection, livers and spleens from Khal-treated mice generated a great deal fewer recoverable CFU. Finally, the antibiotic effects of Khal were evaluated under confocal microscopy after we immunostained the liver sections with anti-Khal antibody. It was concluded that Khal bound specifically to the surfaces of bacteria colonized in the mouse liver and killed the bacteria rapidly.</P>

To initiate an EMS(Emergency Medical System)-based disater plan at Wonju city (population : 170,000), a mock disaster was developed and carried out. The scenario involved a mock train derailment near Wonju Station resulting in 40 casualties (status : 5 dead, 4 urgent, 10 moderate, and 21 non-urgent). The duties of the disaster relief team were determined by the specific situation at that time. The mock disaster was carried out at the Wonju Station plaza on April 29th, 1994 from 2 to 4 PM. The mock disaster was evaluated by timing each level of response and after completion of the simulation, a meeting was held for discussion. The following results were obtained. 1. The reaponse time for reaching the site was ; disaster relief team 6 minutes, emergency relief team 10 minutes, medical support team 20 minutes, and military support team 25 minutes. 2. The time interval from triage (citical, emergency treatment needed patients) to emergency treatment was 80 minutes and was due to the small number of emergency and medical support personnel. 3. The time interval from triage to transportation : (1) Twenty minutes from start of exercise to 110 minutes for the last patient. (2) Urgent patients : First was evacuated after 20 minutes and the last after 80 minutes (average : 42.5 minutes). The critical patient transported after 80 minutes was trapped inside a structure, and therefore time consuming. (3) Moderate patients : First was after 30 minutes and last was 85 minutes (average : 56 minutes). (4) Non-urgent : First was after 35 minutes and last was 110 minutes (average : 90 minutes). All were transported by bus, two were evacuated by ambulance after misjudgement by the emergency personnel. (5) The dead were transported by truck after all living patients were transported. 4. Points discussed at evaluation meeting : (1) The current Winju city's disaster relief personnel lack systematic training. (2) The fire department does not have a specialized relief team, and are lacking in emergency aid techniques and equipment. (3) The police department lacks plans for guiding emergency vehicles and controlling the disaster site. (4) The military hospital had in sufficient and outdated medical equipment, and cooperation with the medical team was poor. (5) There was a definite need of more emergency relief personnel and more training was needed in triage. (6) Cooperation between our medical personnel and the military medical personnel was insufficient. (7) The recognition of critical patient tags by the relief personnel was inadequate. (8) Communication between the relief teams was problematic due to the absence of a wireless communication system. Conclusion : For an effective simulated disaster relief exercise at Wonju city, all relief teams need adequate and sufficient equipment with a systematized training program consisting of a joint exercise at least twice a year. Sufficient emergency relief personnel with adequate equipment should decrease the time consumed at triage and emergency treatment.
