In this paper, we developed a Hospital Information System in which the business process is formalized and a wire/wireless integrated solution is used. This system consists of the administration office program, the medical office program, the ward management program and the rounds management program. The administration office program can enroll and accept patients, issue and reissue the RFID card. The medical office program inputs a medical examination and treatment, outputs a diagnosis, requests a hospitalization, retrieves the record of a medical examination and treatment, assigns the corresponding examination room to the accepted patients, and updates the number of an waiting patient and a patient number according to the examination room on real time. The ward management program handles hospitalizations and leaving hospital, a nurse's note, and an isolation ward monitoring. The rounds management program handles a medical examination and treatment, and a leaving hospital using PDA. This developed system can be built at low cost and increase the quality of the medical services highly by making it automated the medical administration automation. Also the small number of the medical staffs can manage the inpatients efficiently by using the monitoring functions.

Purpose: The study aims at identifying patient-related and environmental factors associated with an increased risk of falling and, therefore, both caregivers and designers can be aware of fall risk factors and can contribute to prevent inpatient falls in their own areas of expertise. Methods: A case-control study has been conducted, utilizing patient data and physical environmental data in the unit of General Medicine in the United States. The case-control study investigated data about patients who had suffered falls as well as patients with similar characteristics (e.g., age, gender, and diagnosis) who did not suffer falls. Results: The study identified both patient-related and physical environmental factors associated with inpatient falls. Morse fall risk score, patient visibility, and patient accessibilityB were identified as significant predictors to inpatient falls, when controlling for other significant variables. Implications: The findings of the study can provide implications to both caregivers and healthcare and hospital environment designers. Caregivers should give special attention to patients with high Morse Fall Risk Scores to prevent inpatient falls. Designers also need to examine and to fine-tune the unit layout of inpatient care units to maximize each patient room's patient visibility from the rest of the unit and patient accessibilityB from working areas of nurses.

Purpose: The purposes of this study are finding the elements for a fast determination of the need for a transfusion to a multiple trauma patient arriving at this clinic in the initial stage establishing objective bases for a doctor in an emergency department to determine the need for a transfusion immediately after a patient has arrived at the emergency department, and providing treatment by considering various factors based on the nine criteria suggested in the emergency room transfusion score (ETS). Methods: This study was conducted on 375 multiple-trauma patients who visited the Chosun University Hospital Emergency Medical Center and activated the Emergency Trauma Team from January 2010 to December 2013. The patients were divided into the transfused group and the non-transfused group by retrospectively analyzing their medical records. Subsequently, the medical records were examined using the nine items suggested by the ETS and the results were analyzed. Results: Three hundred seventy-five patients with multiple traumas visited the Chosun University Hospital Emergency Medical Center and activated the Emergency Trauma Team. Among them, 258 died and 117 recovered and left the hospital. The deceased patients consisted of 182 males and 76 females with an average age 45. Of the 375, 165 were transferred from other hospitals, and 245 were blunt trauma patients. One hundred sixty-nine patients were injured in traffic accidents, and 119 of those 169 who had systolic blood pressure less than 90 mm Hg died. Two hundred twenty-six (60.3%) out of the 375 patients with multiple traumas received an emergency blood transfusion and their average age was 48. The 375 patients consisted of 156 males, 151 who had been transferred from other hospitals, 218 who presented with blunt trauma, 134 who had been injured in traffic accidents, 156 who had a systolic blood pressure less than 90 mm Hg, 134 who scored higher than 9 points on the GCS, and 162 who had a stable pelvic fracture of these 143 died. Conclusion: During this study, 226 (60.3%) out of the patients with multiple traumas received an emergency blood transfusion. After analyzing the results related to emergency blood transfusion by using ETS, we found that an emergency blood transfusion had to be prepared quickly when patients were transferred from other hospitals when the systolic blood pressure was less than 90 mmHg. when abnormalities had been detected by ultrasonography and when the patient presented with a stable pelvic fracture.

We have experienced 2 cases of the hunshot wound sof the chest involving cardiac injuries at department of the thoracic surgery, Capital Armed Forces General Hospital during I year from April I 1979 to Jan. 1980. In one case of two patients , he was a 22 years old man who was transported to this emergency room 4 hour 10 minutes after having gunshot wound of the left chest by helicopter. Physical examination showed small inlet in left 3rd ICS and left parasternal border, large outlet in left 8th ICS and left scapular line, no breath sound on left side and distant heart sound. chest roentgenography demonstrated marked pleural effusion in left side and mediastinum shifted to right. As soon as chest X-ray was taken, the bleeding through penetrating wound became profuse and cardiac arrest ensued. Closed chest cardiac massage was started and vigorous transfusion continued, but no effective cardiac activity could not be obtained. The patient was pronounced dead due to exsanguinating hemorrhage from wuwpected cardiac wounds. In this critically injured patient with evidence of intrathoracic hemorrhage and suspected cardiac penetration, only emergency thoracic exploration and immediate surgical control of bleeding points might offer the maximum possibility of survival. The other case was a 23 years old man who was transferred to the emergency room 4 hours 50 minutes after having kmultiple communicated fractures of sternum and linear fracture of right mandible by a missile. Examination revealed about 30% skin loss of the anterior chest wall, weak pulse of 96 beats/min., distant heart sound and decreased breath sounds bilaterally. finding on the chest X-ray films showed multiple sternal fractures, marked pericardial effusion indicating hemopericardium. So, the patient was moved immediately to the operation room where, after endotracheal tube inserted, a median sternotomy was performced. A hemorrhagic congestion of the right upper lobe and marked bulging pericardium were disclosed. The pericardium was opened anterior to right phrenic nerve and exsanguinating hemorrhage ensued from the 0.5cm lacerated wound in the auricle of right atrium. The rupture site of right atrium was occluded with non-crushing vascular clamps and then was over sewn with interrupted sutures. It was thought to be highly possible that he was alive long enough to have cardiorrhaphy because of cardiac tamponade, which prevented exsanguinating hemorrhage. He was taken closed reduction for linear fracture of right mandible 2 weeks after repair of ruptured right auricle in dental clinic. This patient's post-operative course was not eventful.

This is a retrospective clinical study on 2,955 patients who had visited the Emergency Room of Sang-gye Paik Hospital and then been treated in the Department of Oral and Maxillofacial Surgery during recent 4 years from Aug. 2002 to Dec. 2006. The obtained results were as follows. The total number of patients was 2,955 and the ratio of male to female was 1.72:1. The age distribution peak was the 1st decade (30.8%), followed by the 3rd decade (14.3%) and the 4th decade (14.0%). Trauma (62.3%) was the most frequent cause in dental emergency patients, pulpitis (13.0%) and infection patients were next in order of frequency. In trauma patients group, facial bone injury, tooth injury, soft tissue injury were included and soft tissue injury group was most prevalent, followed by tooth injury group and facial bone group. In total patient, the ratio of admission was 3.5%. We obtained the results of the distribution of primary emergency care in the traumatic injury, causal distribution of the jaw fracture, distribution of related medical department in multiple associated injuries, distribution of emergency care in infection, causal distribution and control methods of oral bleeding, distribution of TMJ disorder. The trauma patient group was major in the dental patients who had visited the emergency room, but other various groups were included. So we should analyze the pattern and the variation of the dental emergent patient to provide the proper treatment.

The purpose of this study was to investigate changes in surface dose due to increased scattering of gamma rays from patients injected with ^99mTc and ¹⁸F, which are radioactive isotopes, in close contact with materials with high atomic number such as the walls of the stable room. Prepare ^99mTc and ¹⁸F by injecting 20 and 10 mCi respectively into the NEMA phantom, and then measuring the surface dose for 60 minutes by positioning the phantom at a height of 1 m above the surface, at a distance of 0, 5 and 10 cm from the wall, and at the same location as the phantom facing the wall. Each experiment was repeated five times for reproducibility of the experiment and one way analysis of variability (ANOVA) was performed for significance testing and Tukey was used as a post-test. The study found that surface doses of 220.268, 287.121, 243.957, and 226.272 mGy were measured at ^99mTc, respectively, in the case of empty space and in the case of 0, 5 and 10 cm, while those of ¹⁸F were measured at 637.111, 724.469, 657.107, and 640.365 mGy, respectively. In order to reduce changes in surface dose depending on the patient's location while waiting, it is necessary to keep the distance from the ground or the wall where the patient is closely adhered to, or install an air mattress, etc., to prevent the scattered lines as much as possible, considering the scattered lines due to the wall etc. in future setup of the patient waiting room and safety room, and in addition to the examination, the external skin width may be reduced.

This study is descriptive research to investigate the effects of COVID-19 stress, interpersonal (caregiver-patient) stress, and emotional labor on burnout in emergency room (ER) nurses during the COVID-19 pandemic. The data collection of this study was conducted from December 9 to 23, 2021 with ER nurses working at five tertiary general hospitals and general hospitals of Medical Center H. The data was collected with a questionnaire using tools measuring the subjects' general & job-related characteristics, COVID-19 stress, interpersonal(caregiver-patient) stress, emotional labor and burnout. The collected data was analyzed using the SPSS/WIN 25.0 statistical program for frequency analysis, descriptive statistical analysis, independent sample t-test, one-way ANOVA, Scheffé test, correlation analysis, and multiple regression analysis. The average score of COVID-19 stress in ER nurses was 3.64, interpersonal(caregiver-patient) stress 4.35, emotional labor 3.38, and burnout 3.44. As a result of analyzing differences according to general & job-related characteristics, burnout showed a significant difference according to gender, marital status, total clinical experience, and working organization. And burnout showed a significant positive correlation with COVID-19 stress, interpersonal stress and emotional labor. As a result of multiple linear regression analysis, regional emergency medical centers and local emergency medical centers among the work organization types, interpersonal stress, COVID-19 stress, and gender and the explanatory power was 28.6%. Through these results, we intend to provide basic data for the development of an intervention program to prevent burnout of emergency room nurses and improve nursing performance at the time of a new infectious disease pandemic.

The proposed application design for emergency medical system includes the functions that help securing the window of opportunity for the patients in an emergency situation and efficiently link rescue agency, emergency medical treatment center and patients together. First, the treatment time can be saved at the emergency room by understanding the patient's condition by entering his/her health information such as anamnesis, family history, social history and blood type together with an identification number. Also, if the siren function which signals whereabouts of patients to the rescue crew is used, it will be much easier to find the location of the patient in need. The design allows rescue crew to call the patient to check whether he/she is conscious or not. Just by receiving the call, he/she will be deemed conscious.

Implantation of Dual Chamber Pacemakers Which sense in the Atrium and the Ventricle, and sequentially or synchronously trigger impulses in the both chambers, has led us to the near realization of the ideal "Physiologic Pacing". We have experienced two cases of implantation of Dual chamber pacemaker in September and October, 1983. One patient was a 21-year-old male who had postoperative complete heart block since he was taken Total correction of TOF in May, 1983 . We implanted transvenously a dual chamber pacemaker, VDD type, through the left subclavian vein. In the other patient who came to the emergency room for partial obstruction of small bowels with severe abdominal pain, nausea and vomiting, in whom heart block was found, we implanted a DDD type pacemaker through the left subclavian puncture. The pacemakers have been functioning well postoperatively for more than two months, and the conditions of patient were uneventful.
