We reviewed 217 patients (270 cases) of thoracic and lumbar fractures and fracture-dislocations, who were treated at Hanyang University Hospital from January, 1977 to December, 1985. We classified spinal injuries according to three column theory and then analyzed the cause of injury, sex-age distribution, treatment and neurological injuries. The results were as follows: 1. The cases were classified into 4 different categories according to the three column theory; compression fractures (191 cases, 70.7%), burst fractures (54 cases, 20.0%), fracture-dislocations(22 cases, 8.2%), and seat belt type injuries (3 cases, 1.1%). And each of these 4 different categories was then subdivided into subtypes. 2. The most common cause of injury was fall from a height (45.2 %). 3. The neurological injuries were occurred in 21 patients (9.7%). The 16 patients with neural deficit in fracture-dislocation, 15 patients were flexion rotation type. The 5 patients with neural deficit in burst fracture, all were incomplete neural deficits. 4. The greatest advantage of Luque instrumentation was an early rehabilitation without external surport.

OBJECTIVES: This study was conducted to develop a Korean version of the Participatory Action Oriented Training (PAOT) program and training materials for improvement of agricultural working environments. METHODS: The PAOT manual and checklist were developed on the basis of the original English version of the training materials, a questionnaire survey of agricultural health and safety professionals, and a brainstorming conference. Good example pictures were collected through visits to agricultural workers' houses, and an easily understandable picture was drawn by an animation specialist. A PAOT action manual and five types of action checklists were developed for use in different agricultural environments. Each action checklist contained six categories and 38 items of agricultural health and safety principles; the six categories were material storage and handling, work stations and tools, machine safety, physical environment, working schedule and organization, and basic health and safety management. Incorporating these training materials, a one-day Korean PAOT program was developed. RESULTS: Among 307 candidate agricultural workers from four rural Korean villages, 94 workers (59 males, 35 females) participated in a PAOT from July 2007 to Oct 2008. The PAOT program was successful and the mean self-estimated satisfaction score of the participants was greater than 90%. CONCLUSIONS: A Korean PAOT program and training materials were successfully developed and applied to Korean agricultural workers. Although more studies are needed, it is expected that PAOT will greatly contribute to the improvement of agricultural working conditions and health and safety through the use of agricultural workers' self initiatives.

Hypoglycemia sometimes manifests as focal neurologic deficits simulating cerebrovascular disease. Symptoms are usually resolved by glucose infusion, but persistent hemiplegia is rarely reported. A 68-year-old diabetic woman on oral hypoglycemic agent(OHA) was admitted with right hemiplegia and global aphasia. Blood glucose level was 29 mg/dl on admission. No evidence of cerebral infarct or underlying brain disease could be found on initial brain CT and follow up MRI. Focal stenosis or occlusion was also absent on MR angiography. Hemiplegia and aphasia were not improved despite adequate therapy. Hypoglycemic hemiplegia should be suspected in all diabetic patients using insulin or OHA with stroke-like episode, and we suggest that prolonged hypoglycemia may be related to persistence of neurologic deficits.

The rupture of ventricular septum complicating acute myocardial infarction requires prompt recognition for the correct management of the patient. The diagnosis of this condition had required right heart catheterization. We performed two-dimensional and Doppler echocardiography in patients with systolic murmur after acute myocardioal infarction. Ventricular septal defect was found at lower interventricular septum by mapping technique of pulsed wave Doppler system and obtained high velocity Doppler tracting by continuous wave Doppler echocardiography. Doppler echocardiography could be useful noninvasive method for detection of ventricular septal rupture after acute myocardial infarction.

OBJECTIVE: For the ubiquity of medical service, when user who has proper authority want to access medical data, user accessability should be assured. And the security of the disclosed medical data is important. This paper presents single user access interface on multiple patient reservoirs and elaborate access control using the Role-Based Access Control(RBAC) system. METHODS: Proposed system consists of 4-tier architecture that is client application, Access Control Central(ACC) agent, Local Access Control(LAC) agent and Hospital Information Systems(HIS). User requests medical data with client application. ACC notarizes user identity and controls access of user request and selectively encrypts medical data. LAC charges data conversion for communication between ACC and HIS. HIS has repositories of medical datum. System provides security service with digital certificate, X.509v3, of user. RESULTS: User requests medical data of several HIS approaching single ACC not by each HIS. Through conversion process of LAC, data that is described XML and is used for communication inter system enables information exchange with single common data format that is independent to several HIS. CONCLUSION: In the proposed system, user accesses medical datum of several HIS regardless of location and has consistent access interface. And using independent format against each HIS makes easy information exchange between several HIS. Transferred data maintains security about significant datum by selective encryption and increases encryption efficiency. Unified access control about multiple patient reservoirs that are scattered in other places provides unified and precise diagnosis of patient information. And it functions the portal of collaborate treatment in inter-HIS.

Carbon monoxide poisoning is one of the most serios health problems in Korea, because we have been encountered with the highest incidence of CO poisoning in the world due to the unique heating system in home called "ondal". We opened Hyperbaric chamber unit in the Seoul National University Hospital last Jan, 1969. We have treated 848 patients as of Sept. 30., 1972, around 44 months period. We collected the informations on the environmental conditions of the place where CO intoxication actually occurred by filling up the questionaire from 505 patients. The following finding were obtained. 1. Age distribution showed that the highest incidence was found in the younger age group between age of 10 to age of 29 in both sex. 2. Sex ratio of the patients was 1:1.14. 3. The socio-economic level of the patient was relatively low. 4. Housewife & housemaid were the major victims of the intoxication in the female patients & in the case of the male patient, occupational backgrounds were diverse. 5. Many patients form the middle class experienced the intoxication bu sleeping at newly built room. 6. Many intoxication has been occurred in the structure of houses where communicating doors are existing between living room & kitchen. 7. All findings obtained taught us again that CO poisoning is the serious by-product of the national fuel policy which put emphasis on the use of coal & socio-economic status is very important parameter in this hazards.

Voltage dependent calcium channel (VDCC), one of the most important regulator of Ca2+ concentration in neuron, play an essential role in the central processing of nociceptive information. The present study investigated the antinociceptive effects of L, T or N type VDCC blockers on the formalin-induced orofacial inflammatory pain. Experiments were carried out on adult male Sprague-Dawley rats weighing 220-280 g. Anesthetized rats were individually fixed on a stereotaxic frame and a polyethylene (PE) tube was implanted for intracisternal injection. After 72 hours, 5% formalin (50 microL) was applied subcutaneously to the vibrissa pad and nociceptive scratching behavior was recorded for nine successive 5 min intervals. VDCC blockers were administered intracisternally 20 minutes prior to subcutaneous injection of formalin into the orofacial area. The intracisternal administration of 350 or 700 microg of verapamil, a blocker of L type VDCC, significantly decreased the number of scratches and duration in the behavioral responses produced by formalin injection. Intracisternal administration of 75 or 150 microg of mibefradil, a T type VDCC blocker, or 11 or 22 microg of cilnidipine, a N type VDCC blocker, also produced significant suppression of the number of scratches and duration of scratching in the first and second phase. Neither intracisternal administration of all VDCC blockers nor vehicle did not affect in motor dysfunction. The present results suggest that central VDCCs play an important role in orofacial nociceptive transmission and a targeted inhibition of the VDCCs is a potentially important treatment approach for inflammatory pain originating in the orofacial area.
