Carbon monoxide which is an odorless, colorless, non-irritating gas causes asphyxia by blocking the hemoglobin of the RBC from carrying oxygen to the tissues and from returning carbon dioxide to the lungs. The clinical symptoms of CO poisoning depend on the blood CO saturation level and in a healthy middle-aged individual a blood CO saturation greater than 50% is considered fatal. In forensic science, the investigation of the scene in cases of CO poisoning is imperative to determine the manner of death or the source of CO production, while postmortem diagnosis of CO poisoning is not difficult. The author reported four cases of CO poisoning in the unusual or atypical circumstances, which were no recognized in the scene.

Background: This study was conducted to analyze the current problems in completing death certificates and to identify the correct method for completing death certificates Methods: We reviewed 262 death certificates in three hospitals from March 1 to April 30, 2000, and 119 death certificates in one hospital from March 1 to 31, 2000. We identified major and minor errors and analyzed and compared them retrospectively. Results: A total of 381 death certificates were reviewed: 59 in Seoul National University Hospital,101 in Ewha Woman's University Hospital, and 102 in Gachon Medical College Hospital, which has no education program for completing death certificates in postgraduate training, and 119 in Samsung Medical Center which has an education program for completing death certificates. 358 certificates(94.0%) had at least one error. There were only 23 death certificates(6.0%) without an error. In 182 cases(47.8%), there was one major error. In 321 death certificates(84.3%), there were more than two errors. A comparison of Samsung Medical Center with the other hospitals showed that the number of total errors was statistically different(p=0.001). Conclusion: There were few death certificates without an error in this study. In a hospital which has postgraduate training in completing death certificates, there are fewer errors than in other hospitals which have no training course. Emergency physicians actually certify many deaths, so they must know the correct method of completing death certificates for statistics on morbidity and mortality.

It will be the crucial condition to provide people with the excellent and interesting game so that the techniques of competition would be advanced and everyone loves Taekwondo as National sport, which will be adopted in Sidney Olympic gasses. And it will help Taekwondo be adopted permanently. We suggested a scheme of partly developed competition rules on the current Taekwondo. Each of us thinks only theoretically that this direction of contents will be the standards for advancement of Taekwondo competition. But we wrote this paper with the belief that the contents of Taekwondo competition developed should be scientific and reasonable in order that they can be the new start point for Taekwondo advancement, The followings are my suggestion for Taekwondo advancement 1) It is necessary to change the rules, so it should be possible to select the various colors of ground and uniforms, five-minute gave and gradation credits. It will make Taekwondo be loved by the whole world and be adopted permanently in Olympics. 2) It is necessary to adjust the grades of each weights corresponding to international standard height and to found the more professional Taekwondo teams so that they can activate the amatuer Taekwondo players. 3) The main basic principles of Taekwondo are based on the philosophical thoughts. It is necessary to study the detailed programs according to pratice-process from the martial and competitional aspects corresponding to grades and ages. 4) It is also necessay to hold competition on Pumsae. 5) It should be realized to build the create Taekwondo Meca Center, which represents the holy Korean spirits.

It has been demonstrated that brief period of ischemia and reperfusion (ischemic preconditioning, IP) enhances recovery of post-ischemic contractile dysfunction and reduces incidences of reperfusion-induced arrhythmia or infarct size after a prolonged ischemia. Recent studies suggest that IP triggers activation of protein kinase C (PKC). In the present study, the author teated this hypothesis with PKC activator, phorbol ester (PMA, 0.01 nM) or inhibitor, calphostin C (200 nM) to measure the left ventricular function and infarct size; and assessed whether hemodynamics are related with each other or not. Hearts isolated from New Zealand White rabbits (1.5-2.0 kg body weight) were perfused with Tyrode solution by Langendorff technique. After stabilization of baseline hemodynamics, the hearts were subjected to 45 min global ischemia followed by 120 min reperfusion with IP (IP group, n=7) or without IP (ischemic control group, n=7). IP was induced by single episode of 5 min global ischemia and 10 min reperfusion. In the PMA-treated group (n=13), the heart was subjected to perfusion with Tyrode solution containing PMA for 5 min after stabilization of the baseline, washing out (for 10 min with normal perfusion), and 45 min ischemia and 120 min reperfusion; in the calphostin C-treated preconditioned group (n=15), calphostin C was given for 15 min from 5 min before IP regimen. Left ventricular function including developed pressure (LVDP), dP/dt, heart rate, left ventricular end-diastolic pressure (LVEDP) and coronary flow (CF) was measured. Iinfarct size was determined by staining with tetrazolium salt and planimetry. Data were anaalyzed by one-way analysis of variance and Tukey's post-hoc test; and linear regression between hemodynamic values. In comparison with the ischemic control group, IP signifivantly increased the recovery of the left ventricular function including left ventricular developed pressure, contractility, and coronary flow. However, enhancement of the functional recovery disappeared by calphostin C or PMA treatment. IP and PMA also reduced infarct size (from 38 to 10-20%, p<0.05). However, calphostin C blocked infarct reduction effect of IP. These results suggest that in isolated Langendorff-perfused rabbit heart model, IP could improve post-ischemic contractile dysfunction, as well as it has an infarct size-liniting effect; these cardioprotective effect of IP may be related, at least in part, to trigger activation of PKC, however, there are any relationship between hemodynamics.
