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.

만성 알코올리즘 환자의 치료 방법 중 혐기요법의 하나로 Disulfiram요법을 시행하여 뇌증후군 및 정신병적인 증상을 일으킨 1예와, 금주 목적으로 의사의 지시없이 Disulfiram만을 복용하여 급성 정신증상을 유발한 1예를 치험하였기에 보고한다. It is well known that disulfiram therapy may result in psychosis, organic brain syndrome, and peripheral neuropathy, additional to the wanted effects of the drug. We experienced two cases of psychoses in chronic alcoholisms who had no past history of psychosis: one; organic brain syndrome and psychotic symptoms resulted from the therapy, the other, acute psychotic symptoms resulted from arbitral taking of disulfiram only, aimed to stop drinking. It is said that the symptoms will disappear only by stopping the medication. Therefore, we assume that disulfiram therapy can be effective as the adjunctive therapy only when it is tried by physicians, and that arbitual usage by general population should be restrained.

The purpose of this study is to measure the changes of regional cerebral blood flow (rCBF) and blood pressure (BP) of Cortex Acanthopanacis in rats, and to determine the effect of Cortex Acanthopanacis on phenylephrine (PE) induced contraction of isolated rat thoracic aorts. The measurement was continually monitored by laser-doppler flowmeter (Transonic Instrument, USA) and pressure transducer (Grass, USA) in anesthetized adult Sprague-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. Contractile force was measured with force displacement transducer under 1.5 g loading tension. The result of this experiment was as following; 1. Cortex Acanthopanacis did not effect the changes of rCBF and blood pressure significantly. 2. Contractions evoked by phenylephrine were decreased significantly by Cortex Acanthopanacis 3. L-NNA, ODQ, atropine and indomethacin significantly altered the relaxation of Cortex Acanthopanacis. 4. Propranolol did not change the relaxation of Cortex Acanthopanacis. These results indicate that Cortex Acanthopanacis did not change the rCBF and BP, but Cortex Acanthopanacis can relax PE induced contraction of isolated rat thoracic aorta and that this increasing contraction related to endothelium and various mechanism.

C. S. CHOI, I. S. SHIN, J. S. SEO. Evaluation of the Impact Force on the Vertically Placed Force Platform. Korean Journal of Sport Biomechanics, Vol. 14, No. 2, pp. 57-68, 2004. This study was to evaluate the consistency of the vertical force( Fz) of the force platform and the impact force. Two experiments were performed. First, the force platform was vertically placed to hang to the wall. While the rotating iron body hit the force platform, Fz was measured. Then FZ was compared with the impact force of the rotating iron body that was precalculated by using the inertia moments and the rotating force. Second, six Taekwondo masters punched the force platform to show what a certain pattern the impact force has. They were asked to punch the target depending on target distances. The target distances were differed from the relative arm segment of subjects as 90%, 80%, 70%, 60%, and 50% (100% target distance equals the arm length of each subject). Pearson 's correlations were used between Fz and the impact force. Also the linear regression was also performed to show the linearity. At the first experiment, Fz and the impact force had much correlations and showed linear characteristics. Therefore, F, could be regarded as the impact force. At the second experiment, the strongest impact force was measured at the target distance of 80% and the time taken to the maximum impact force was within 0.02 seconds. The result of this study recommends that it can help the comparative study between the impact forces and other hitting sports.

This study was aimed at the research of the sports injuries with 140 handball players in boys' middle school who took part in the 23rd National Athletic Meeting in 1994. With the analysis of their reply for the questions, we could found the time, the causes, the region, the sort and the treatment of the sports injuries. Analysis of these data was used by the percentage and χ²verification(p< .05). The results are as follows; 1) There were 135 players gotten sports injuries among 140 members (96%) and we found 382 times' sports injuries, that is, 2.7 times per all players and 2.8 times per injured players. 2) We found that 70.9% of the target players were injured in training and 29.1% in the game. By the player's experience, we could see that the more experience, the less injuries in training and the more injures in the game. With the season, there were a lot of injuries players in spring. 3) The causes for the sports injuries, in warming up, turned out to be 39.3% by the players carelessness, 24.5% by the lack of enough warming-up and 13.4% by the excessive will for winning the game. 4) With the regions of the sports injuries, some players (38.5%) had injured on their arms, some players (30.1%) on their legs and others (17.0%) on their abdomen. With the playing positions, many players got injured on their arms and legs. 5) In the kinds of the sports injuries, we found that many players had injured on the part of joint (37.2%), the muscle (25.9%), the bone (18.6%) and on the skin (18.3%). As the playing positions, most goal-keepers had injured on the part of muscle and many field-players had on the joint and muscle regardless of the playing positions. There seemed to be no difference between the playing positions and the kinds of sports injuries in range of p>0.05. With the injuries of the bone, we could found the bruise (69.0%) and the fracture of the bone (28.2%). But among the target players, there were found only two players who had the osteomyelitis. In the sports injuries of the joint, many players got the asprain (50.7%), the injury of ligament (29.6%) and the luxation (16.9%). Most goal-keepers got the the injury of ligament (45.0%) but most field players got the injuries of the the part of skin, we could get the results of laceration (54.3%), abrasion (35.7%) and the fracture (10.0%) for all playing positions. In the injuries of muscle, there were the muscle bruise (67.7%) and the muscle regidity (32.3%). 6) In the methods of the first aids, after gotten the sports injuries, most players were treated for themselves (49.0%), and some players (3.4%) by a herb doctors.

Antioxidative activities (AA) of mustard leaf kimchi (MLK) by the addition of optional ingredients among selected minor materials were studied. In order to determine AA of MLK with different spices, the model systems of ground cooked beef with green onion, garlic, and red pepper powder were prepared and stored for 4 weeks at 4℃. AA of red pepper added group was stronger than those of others. AA of red MLK was relatively higher than that of (green) MLK. For the enhancement of AA of MLK, another model systems were prepared with the selected antioxidative optional ingredients, which were bonnet bellflower root, leek, burdock, sea tangle, sea mustard, seastaghorn at the level of 2% or 4%. The extracts of water, 75% methanol and hexane of MLK, bonnet bellflower root added MLK, and seastaghorn added MLK had a considerable AA with the inhibition of peroxide formation during the autioxidation of linoleic acid mixtures in aqueous model systems at 37℃. Therefore, AA was more effective in MLK containing specific optional ingredients than that of MLK alone significantly.
