From April 1982 to December, 1988, multiple valve replacement was performed in 49 patients. Mitral and aortic valve replacement were done in 42 patients, 4 underwent mitral and tricuspid valve replacement and 3 patients underwent triple valve replacement. Of the valve implanted, 50 were Duromedics, 21 St. Jude, 13 Bjork-Shiley, 9 Carpentier-Edwards, 6 Ionescu-Shiley, and 2 Medtronic. The hospital mortality rate was 28.5 % [14 patients] and the late mortality rate was 6.1 % [3 patients], the mortality rate was high in early operative period but decreased with time. [20% at 1986, 18.2 % at 1987, 9.5% at 1988] The causes of death were low cardiac output in 8, congestive heart failure in 2, multiple organ failure in 1, LV rupture in 1, intracerebral hemorrhage in 1 and sudden death in l. The actuarial survival rate excluding operative death was 77% at 7 years.

From August, 1986 to December, 1993, mitral valve replacement was performed in 178 patients. Of the valve implanted, 114 were St.Jude Medical, 47 Duromedics, 16 Carpenter-Edward and 1 Ionesc-Shiley. The hospital mortality rate was 2.8%[5 patients and the late mortality rate was 7.5%[13 patients . The causes of hospital death were LV rupture in 1, renal failure in 1, cardiac tamponade in 1, valve malfunction in 1 and hypoxic brain damage in 1. The causes of late death were sudden death in 6, congestive heart failure in 4, brain ischemic injury in 3. Follow-up was done on 155 surviving patients : mean follow-up period was 50.94$\pm$8.04 months. The actual survival rate was 88.2% at 8 years. We concluded, therefore, that good clinical results could be achieved with mitral valve replacement in mid-term follow-up, and long-term follow-up is also necessary.

Progressive muscular dystrophy (PMD) is a primary muscle disease characterized by progressive muscle weakness and wasting, which is inherited by an X-linked recessive pattern and occurs mainly in males. There are several types of muscular dystrophies classified according to the distribution of predominant muscle weakness including Duchenne and Becker, Emery-Dreifuss, facioscapulohumeral, oculopharyngeal, and limb-girdle type. Clinical manifestations of PMD are clumsy, unsteady gait, pneumonia, heart failure, pulmonary edema, hydropericardium, hydrothorax, aspiration, syncopal attacks, and sudden cardiac death. The deceased was a 34-year-old man, and the onset of the first clinical symptom, gait disturbance, was in his late teens. His elder brother had the same disease and experienced brain death after a head trauma and died after mechanical ventilation was discontinued. After an autopsy, we found contracture of the joints, pseudohypertrophy of the calf, wasting and fat replacement of the thigh muscle, pericardial effusion (80 mL), fibrosis and fat replacement of the cardiac ventricular wall, pulmonary edema, and froth in the bronchus. The cause of death was heart failure and dyspnea due to muscular dystrophy. There was no sign or suspicion of foul play in his death.

The result of Bibliographic studies on the pathological mechanism of the sudden coma, we got the conclusion like this. 1. The sudden coma is an acute syndrome that refers to be a sudden fainting, an unconsciousness, an aphasia or a cold clammy limb, and immediately awakes or dies, and awakes in a short time, and if we awake, it doesn't leave over and above a sequela. 2. The clinical presentation of the sudden coma can be summarized as follows : The 1st is a disease raising the sudden death due to unconsciousness accompanied by wry mouth & sudden syncope with coma. The 2nd is simply the state of cold limbs. The 3rd is the meaning of the physique and symptomes of the six meridians. The last is the ancient method of expression in contrast of the beriberi. 3. The pathological mechanism of the sudden coma consists of the toxoid from outside, Qi and Xie, fatigue, damp phegm, the damage from seven emotions and the damage from five mental elements, especially the mental disorder due to the angry energy, causes the problems when the fleming-up of liver fire and the depressed of liver qi raise the physiological disorder. 4. Therapeutic methods of sudden coma are soothing the liver and remove stasis, soothing depression and circulating of the qi, calming the liver and suppressing yang. When that is early stage, at first, we must checking upward adverse flow of the qi after promoting the circulation of qi and awakening, and then, we must regulate excessive deficiency of yin yang by therapy that is based on differentiated in symptoms according to heat & cold, deficiency & excess, and use invigorating herb medicine for supporting vigour.

Sudden infant death syndrome(SIDS) continues to be general cause of infant death. Also, apnea is supposed to be one of the main risk factor of SIDS. Therefore, Infant's respiratory monitoring and real-time apnea detection is very important to prevent SIDS. In this study, we proposed a non-contact home monitoring system for infant's respiration using Doppler radar in order to prevent SIDS. The respiration data were acquired from a commercialized baby simulator(Simbaby$^{TM}$) using a Doppler radar. To evaluate a performance of the proposed system, the simulator was placed in a supine and prone position and the chest belt was used simultaneously as a reference signal. As a result, correlation coefficients between respiration rates of Doppler radar and the chest belt in each position were 0.95(p < 0.001) and 0.98(p < 0.001), respectively. The averages of difference were $-0.29{\pm}5.21(mean{\pm}1.96{\cdot}$ standard deviation) in supine and $-0.12{\pm}3.05$ in prone from Bland-Altman analysis. The results indicated an excellent performance in detecting apnea with a sensitivity of 100% and a positive predictive value of 100% in each posture respectively. These results demonstrated that a proposed Doppler radar system is suitable for non-contact respiratory monitoring in order to prevent SIDS of infant.

Death and dying of human being is a comprehensive system, and death orientation, the subjective meaning related to every component of the death system is developed throughout life. This study was designed and carried out to identify, describe and classify the orientations of Korean adult towards the death system. In an attempt to measure the subjective meaning of death and dying, unstructured Q-methodology was used. The 65 Q-statements developed by Kim(1994), used by Kim(1994) and Park(1996) were adopted as Q-population and 39 Q-statements were selected by the three researchers for Q-items for this study. Thirty-three P-samples were sampled from P-population of literate Korean men and women, 35 and 55 years of age, lived in urban Korea for the last 10 years. Sortings of the 39 Q-items according to the level of personal agreement, and a forced normal distribution into the 9 levels were carried out by the P-samples. The Z-scores of the Q-sort data were computed, and the principal components factor analysis by PC-QUANL Program were carried out. The demographic, socio-cultural and health-related attributes of the P-samples were descriptively analysed. Eight types of death orientation were identified ; Type I ; 'naturalist'. Six P-samples. Death is a natural phenomena, to be accepted as it is and to follow its natural course. Prefer to be informed of all facts and possibilities concernig the course of dying and death to occur to self. Type II ; 'life-after-life negator'. Three P-samples. Time and process of death is the destiny of each person. Death means 'darkness' and 'end to every thing, the absolute end'. Yet, wish physical integrity at the dying and after death. Type III ; 'life-after-life believer'. Six P-samples. Men are travellers passing by this life bound to the life-after-life. Priority concerns are on the activities to prepare self for the eternal life ahead. Disregard premature and sudden death. Type IV ; 'here-now believer' Five P-samples. Positive regard to the cremation of the body and donation of the organs on death. Regard religious and customary post-motem rituals meaningless. Negate life-after life. Type V; 'believer of rituals'. Five P-samples. Death being accepted as a part of, a natural end to, and destiny of human life. Concerned to ensure a dignified end to personal life and dignified post-mortem rituals. Type VI ; 'Realist'(derived from Type I). Two P-samples. Life and death as universal reality. The abrupt death at golden age at the peak of happiness is favored to avoid inevitable physical and mental distress of self and the family. Agreed to the cremation of the body. Disregard rituals. Type VII : 'Fatalist' (derived from Type II). Five P-samples. Not favored, yet, all man are destined to death, the inevitable end of all living beings. To ensure dignified end by personal consummation, information on one's dying and imminent death are to be shared. Type VIII ; 'reality avoider'(derived from Type III). One P-sample. Negative to longevity, artificial prolongation of, meaningless and distressful life. Highly positive to postmortem organ donation.

This study was to investigate the social workers' psycho·social experiences and roles during the end-of-life care process in elderly long-term care facilities. As a result of data analysis through in-depth interviews, social workers experienced great exhaustion and burnout due to frequent death experiences during the end-of-life care process, and expressed regret for not being able to provide better service for the deceased and longing for loved ones. And in the event of a sudden death, social workers would undergo criticism and complaints. The main roles of social workers during end-of-life care were to contact and communicate with family members when signs of death appeared and support them after the death. The necessity of standardized manuals and education for end-of-life care, a recharging program and support group to prevent burnout of social workers, and a legal safety net for emergency preparedness and emergency measures were suggested. The necessity of death preparation education, hospice care, and advance medical directive was also emphasized for the dignified death of the elderly.

An autopsy is a postmortem assessment or examination of a body to determine cause of death or manner of death. The author had surveyed Personnel's perception toward conducting an autopsy in general hospital with autopsy at YeungNam University Medical Center, Daegu, Korea from April, to May, 2007. The total number of 286 personnel consisted of 121 men(42.3%), 165 women(57.7%). There were 57 doctors(19.9%), 71 nurses(24.8%), 83 medical technicians (29.0%), 58 office workers(20.3%), and 17 others(5.9%). 61.4% of doctors had an experience of education for autopsy more than 2 times, but nurses(1.4%), medical technicians(15.7%), office workers(1.7%), and others(5.9%) had little experience. Response of conducting an autopsy for sudden death of respondent or respondent's family member was 59.6% of doctors, 22.5% of nurses, 39.8% of medical technicians, 41.4% of office workers, and 35.3% of others. Response of conducting an autopsy for sudden death of respondent's companion was 66.7% of doctors, 33.8% of nurses, 39.8% of medical technicians, 43.1% of office workers, and 17.6% of others. Response of conducting an autopsy for sudden death of patients in general hospital was 50.9% of doctors, 8.5% of nurses, 19.3% of medical technicians, 24.1% of office workers, and 17.6% of others. Survey about a proper institution for autopsy showed 73.7% of doctors for department of forensic medicine in medical school, and 62.0% of nurses, 59.0% of medical technicians, 46.6% of office workers, and 58.8% of others for National Institute of Scientific Investigation. Most of the respondents agreed with the forensic pathologist as the director of autopsy:98.2% of doctors, 94.4% of nurses, 96.4% of medical technicians, 89.7% of office workers, and 88.2% of others. Survey for necessity for autopsy showed responsiveness of doctors, 23.9% of nurses, 47.0% of medical technicians, 34.5% of office workers, and 23.5% of others. Survey for donation of him- or herself after death to the medical school or institution for the death investigation revealed responsiveness of 22.8% of doctors, 11.3% of nurses, 24.1% of medical technicians, 22.4% of office workers, and 23.5% of others. The result of the survey questionnaire showed more negative awareness for autopsy in nurses, medical technicians, office workers, others and than doctors. To improve the negative awareness for autopsy and settle proper postmortem inspection system, education of professional manpower for forensic medicine and inaction of law which is adequate for the actual circumstance of Korea should be considered.
