Fire characteristics of a typical apartment building in Korea was studied through full scale experiment and zone model simulation. The fire was ignited at the living room and allowed to spread to other parts of a single unit in a five storied apartment building. Various data including temperatures, species concentrations, and images were collected in the experiment. A zone model(CFAST) was used to analyze the same apartment building that represents the average households in Korea. The results were compared with a full scale experiments. While CFAST allows one compartment involved with fire, the experiment allowed the fire to spread to other compartments. Therefore, the comparison between experimental data and Zone-Model data is valid until the living-room fire spread to other parts of the apartment. Flashover occurred at approximately 380 seconds in a fire experiment, and at approximately 420 seconds in Zone-Model. Based on all of data between experimental data and Zone-Model data, it is concluded that the safe escape time is about 250 seconds.

The term osteomyelitis literally means inflammation of bone marrow. It is described as an inflammatory condition of bone primarily engaging the medullary Following circulatory collapse and ischemia, the involved portions of the bone become necrotic. Cellulitis and osteomyelitis are the most frequent complications of fractures of the mandible and maxilla, because there is an abscessed tooth in the line of fracture. Since most fractures are compound fractures, infection may develop because of contact with oral secretions or outside air. The treatment of chronic osteomyelitis is still under debate. Some authors rely on antibiotics alone, while others advocate combination with surgery. But when infection occurs, establish proper drainage and administer antibiotics. Author treated a case of infected mandibular fracture with mandibular osteotomy, sequestrectomy, iliac bone graft and hyperbaric oxygen therapy, who had suffered suppurative osteomyelitis and mandibular nonunion following the open reduction of the mandibular fracture.

To study the pseudocholinesterase acticity and its clinical significance in patients with acute organophosphate poisoning, Authors checked the serum cholinesterase activity in 49 normal subjects and 31 acute organophosphate poisoned patients. The results were followings. 1. The mean pseudocholinesterase activity f normal subjects was 1271 IU/L in male and 1131 IU/L in female. The total mean cholinesterase activity was 1209/ IU/L. 2. The pseudocholinesterase activity of patients were significantly reduced compare to normal. 22 patients(73%) were below 10% of normal, 6 patients(20%) were between 10-20% of normal and only 2 patients (7%) were between 20-50% of normal. 3. As a whole there was more depressed cholinesterase activity in patients with comatous and drowsy mentality, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference presented. 5. The mean arterial blood gas checked on arrival was pH 7.386, PaO?? 66mmHg, PaCO?? 38mmHg 02 Saturation 91%. There was noted no statistically significant correlation between pseudocholinesterase activity and these parameters. 6. The pseudocholinesterase activity on the 1st day of admission was 5.7% of normal and progressively increased during admission. On the 14th day of admission, the pseudocholinesterase activity was 35.5% of normal and it takes 20 days to reach 50% of normal. Authors concluded that serum cholinesterase activity of acute organonphosporus poisoned patients were markedly depressed and progressively increased during admission. As a whole the pseudocholine-sterase activity seemed to be related to the clinical findings but no statistically significant difference was found.

The nursing home for the elderly has a weak point for evacuation from the fire because most of all the users are suffering from a dementia or paralysis. When it comes to night shift, it is much difficult to get them evacuated due to the lack of staffs. In addition to that, the nursing home for the elderly has such a strict control system for access that does not have a utility for escape opening. That is why they need the differentiated evacuation planning. This study is to consider the point at issues on the present conditions of law svstem and evacuation plans for the nursing home for the elderly that has some difficulties because of impaired functions of residences. This study dealt with the point at facilities and operations of the emergency evacuation system. First of all for the point at the facilities, I found that it need to be considered on the characteristics of the elderly who has any difficulties of the self evacuation. And the established regulation did not reflect the characteristics of closed area of the nursing home for the elderly. The second, for the point at the operation of the institutions, it is pointed that there seems to be a lack of ways to manage to a emergency situation and educations on the operation staff. And the last, for the point at the operation, the requirement for the managers of fire prevention facilities are similar to that of a normal building. Furthermore there is a lack of corporation with the fire station.

Background : Dental hygienists are at risk of acquiring infections through exposure to infectious agents. This study explores the frequency of exposure to infectious agents and infection control practices among dental hygienists. Methods : We undertook a cross-sectional survey to examine the exposure to infectious agents and infection control practices among dental hygienists through questionnaire. Data were obtained from 124 dental hygienists attending educational conferences. A multiple logistic regression analysis was conducted to determine the factors that effect infection control practices in to age, completion of infection control education, recognition of their own serum hepatitis Ag/Ab status, the number of one day patients, location of clinics, type of clinics, and career years. Results : Of the 124 dental hygienists, 91.7% were exposed to at least one accident such as needle strike injuries during their practices periods. The health screening coverage rate in dental hygienists was 16.5%. The number of one day patients and career years were important in relation to infection control practices among dental hygienists. The adjusted odds ratio estimates for career years were 5.049 times greater(95% CI 1.238-20.597)for groups with 4 career years than under 2 career years. That for the number of one day patients were 0.261(95% CI 0.071-0.0955)lower for through 20 up to 30 patients, 0.531(95% CI 0.102-2.78)lower for through 30 up to 40 patients and 0.498(95% CI 0.123-2.017)lower for more than 40 patients than under 20 patients. Conclusion : From these results, prevalence of infection control practices among dental hygienists is related to the number of one day patients and career years. Prevention of cross infection and reduction of future transmission should be a priority to dental hygienists for promotion of infection control and further efforts to educate newcomers on infection prevention should be made.

Early reperfusion can prevent myocardial necrosis, and clinical trials with reperfusion therapy demonstrating a significant reduction in acute myocardial infarction(AMT) mortality have dramatically changed the treatment paradigm for AMI. All patients with symptoms and ECG findings suggestive of AMI should be considered for treatment with thrombolytic agents. However, only a minority of AMI patients actually receive a thrombolytic therapy. Many patients are often excluded from treatment because they do not meet the criteria for age, duration of the chest pain, and a qualifying ECG. And late arrival at the hospital is a frequently cited reason for not giving a thrombolytic agent. To confirm the reason for not receiving an early reperfusion therapy, we obtained the data for the clinical characteristics, the time intervals between the symptom onset and the start of a thrombolytic agent infusion, the method of reperfusion therapy, the reason for not giving a thrombolytic agent and overall outcomes by retrograde chart review. During the 12-month study period between July 1994 and June 1995, 113 patients were finally diagnosed to AMI, who presented to Emergency Center of Ajou University Hospital in total 30,819 patients. The results were followings: 1. The average age was 59±12 years old, the ratio of male to female was 3.2:1. The direct visited patients to our hospital were 31 and the transfered were 82. 2. The chief complaints were chest pain(86.7%), dyspnea, dyspnea, and mental change. The common preceding diseases were angina pectoris(10 cases), old myocardial infarction(9 cases), congestive heart failure(2 cases) and typical chest pain but not diagnosed(23 cases). The risk factors were smoking(81 cases), hypertension (46 cases) and DM (22 cases). 3. 75 patients had arrived within 12 hours from symptom onset and 38 patients after 12 hours. 45cases (54.7%) were performed the reperfusion therapy ; 31 patients were taken the thrombolytic therapy by tissue-type Plasminogen Activator. 4. The most common reason for not receiving a reperfusion therapy was the time delay and the main was the patient/bystander factor. 5. 75.2%(85 cases) of the patients discharged with or without complications, 7.1% (8 cases) died, 10.6% (12 cases) discharged moribundly, and 7.1% (8 cases) discharged against advise. In conclusion, the time delay was the first reason for not receiving a reperfusion therapy in AMI patients. And the education for the AMI symptom and BLS (Basic Life Support) to the people, good EMS(Emergency Medical Service) system, early definite diagnosis and aggresive therapy may decline the mortality rate.
