The main purposes of this study were to determine the time interval between the onset of symptoms of myocardial infarction and treatment-seeking time and to identify the factors related to the interval time. This study used a retrospective design. The sample consisted of 45 patients aged over 30 who were diagnosed with an acute myocardial infarction at two large university affiliated medical center from September 1, 1997 to June 30, 1998. Data was collected by using questionnaries, which included demographic data, permonitory clinical signs and symtoms of myocardial infarction, and a measure of the severity of the signs and symptoms. Also semi-structured interviews and chart reviews were used to obtain information related to treatment-seeking time. The results of this study are summarized as follows ; 1. The most frequent premonitory clinical symptom was chest pain(92.9%), the second, was perspiration(81.0%), and the next were nausea(40.5%) and dyspnea(38.1%). Thirty two patients reported having more than four premonitory signs and symtoms. Patients described the characteristics of chest pain as “somethings very heavy pressing down”(26.2%), “felt like my chest would burst”(24.4%), or “sharp pain”(16.7%), Over 95% of the sample reported having chest pain. 2. Twenty two (52.4%) patients reported to have “very severe” premonitory pain. 3. The mean time interval between the onset of signs and symptoms and the arrival at the medical center was 6.39$\pm$10.80 hours in 42 samples, the mean time from the onset to arrival at a local hospital was 3.27$\pm$5.39 hours and for transfer from a local hospital to the medical center was 4.75$\pm$9.87 hours in patients who had arrived at medical center via local hospital. 4. The severity of premonitory signs and symptoms did not differ significantly according to existence of premonitory signs and symptoms. 5. There was no significant relationship between treatment-seeking time and age, gender, marital status, economic status, occupation, or residence. But education had significant relationship(r=-0.51, p=0.01). Analysis of difference of the time interval according to the premonitory signs and symptoms showed that the time was shorter in patients who experienced nausea or dyspnea(U=115.50, p=0.01, U=132.00, p=0.04), however the severity of premonitory signs and symptoms did not have statistical significance.

Increasing of number of people who suffered from long term chronic diseases which required frequent daily health monitoring and body check up in conjunction with the trendy uses of mobile phones and Personal Digital Assistants (PDAs) in various ubiquitous computing had make portable healthcare system a well known application today. A mobile phone based portable healthcare monitoring system with multiple vital signals monitoring ability at real time in WSN and CDMA network is developed. This system carries out real time monitoring and local data analysis process in the mobile phone. Any detection of abnormal health condition and diagnosis at earlier stage will reduce the risk of patient's life. As an extension to the existing model, a pre-diagnosis management system (PDMS) is designed to minimize the time consuming in pre-diagnosis process in the hospital or healthcare center. An alert is sent to the web server at the healthcare center when the patient detects his health is at critical state where the immediate diagnosis is needed. Preparation of diagnosis equipments and arrangement of doctor and nurses at the hospital side can be done earlier before the arrival of patient at the hospital with the help of PDMS. An efficient pre-diagnosis management increases the chances of diseases recovery rate as well.
Purpose: This study was conducted to compare pain, sense, bleeding, and hematoma that patients feel depending on the process of eliminating air of pressure band that was applied to patients after percutaneous coronary intervention (PCI) through radial artery. Methods: It was a nonequivalent control group pretestposttest design to compare pain, sense, bleeding, and hematoma by amount and time of eliminating air of pressure band after PCI through radial artery. Results: On arrival at Coronary Care Unit, meaningful difference didn't exist between pain and sense, however, after two hours of starting eliminating air, the points of pain and sense were meaningfully low (p<.001). Also, there was meaningful difference in reciprocal action between group and time (p<.001). Conclusion: After PCI, the conclusion showed there is positive effect in decreasing wrist pain and sense without any influence of bleeding by eliminating air from patients' pressure bands.
Purpose: The "golden hour" concept in trauma is pervasive despite little evidence to support it. This study addressed the association between prehospital time and in-hospital mortality in seriously injured abdominal trauma victims. Methods: A retrospective study was conducted over a three-year period from 2006 to 2008. We analyzed trauma victims with abdominal injuries who underwent an emergency laparotomy in a local emergency center located in a city with a population of 2,500,000. According to the 'golden hour' oncept, we separated the trauma victims into two groups (Gourp 1: prehospital time ${\leq}$ 1 hour, Group 2: prehospital time > 1hour) and investigated several factors, such as time, process, and outcome. Results: During the period from January 2006 to December 2008 139 trauma victims underwent an emergency laparotomy, and 89 of them were enrolled in this study. Between the two groups, emergency department (ED) access, transportation, and injury mechanism showed statistically meaningful differences, but no statistically meaningful differences were observed in various measures of the outcome, such as length of hospital stay, length of Intensive Care Unit stay, and mortality. In a univariate logistic regression study, age (odds ratio [OR]: 1.101; 95% confidence interval [CI]: 1.026 to 1.182), Revised Trauma Score (RTS) (OR: 0.444; 95% CI 0.278 to 0.710), hemoglobin (OR: 0.749; 95% CI: 0.585 to 0.960), and creatinine (OR: 24.584; 95% CI: 2.019 to 299.364) were significant prognostic factors, but prehospital time was not. In a multivariate logistic regression study, age and RTS were significant associated with mortality. Conclusion: In this study, we found no association between prehospital time and mortality among abdominal trauma patient who underwent an emergency laparotomy. We suggest that in our current out-of-hospital and emergency care system, until arrival at the hospital time may be less crucial for trauma victims than once thought.
Purpose: To analyze the data of patients who suffered trauma in a cultivator accident and visited the trauma center in rural Gyeongbuk Province. Methods: We retrospectively reviewed the medical records and Korean Trauma Data Bank data of 120 patients who suffered cultivator-related traumas and visited the rural regional trauma center in Gyeongbuk Province from January to December 2015. Results: The age of the patients ranged from 35 to 96 years (mean, 70 years). Ninety-one (75.8%) patients were men, and twenty-nine (24.2%) were women. Most of the patients were in their 70s (46 men [50.5%] and 13 women [44.8%]). In total, 113 patients (94.1%) arrived at the regional trauma center by ground transport and 7 (5.9%) arrived by air transport. Ninety-eight patients (81.7%) were transported to the regional trauma center directly from the scene of the accident, and twenty-two (18.3%) were transferred from another medical institute. The mean time from the accident to arrival at the emergency department was 139 minutes, and only 46 patients (38.3%) arrived within 1 hour. Twelve (10.0%) patients died, including two deaths on arrival and two post- cardiopulmonary resuscitation deaths in the emergency department. All deaths were of male cultivator operators. The causes of death were shock (hypovolemic, traumatic, or septic), subdural hematoma (open), hemothorax, rhabdomyolysis, and pneumonia. Conclusions: As the government - led regional trauma center project is on process, it would be clinically important to summarize the initial outcome of cultivator injuries, which are characteristically found more in regional trauma centers in the rural area, and have high mortality. Based on this study, in the future, it will be necessary to follow up and analyze more number of patients and to construct accurate database about trauma cases related to cultivator in Gyeongbuk region.

Medical consumers(patients) want evening-clinic because of busy work. For patient's convenience and improving service, hospital should accept it. Considering payment system and patient's demand, personnel expenses, hospital can not accept. The practice of shift system to accept patient's demand and hospital's economic aspect was made. To analysis the effect of the system and probability to alternative to evening clinic this study was done. This study was composed of basal study, intervention, evaluation of effect. The basal study were composed of studying demand on evening clinic, the number of beds, doctors employee, the time table of practice and work, and the number of patients at arrival time. The intervention composed of changing of practice time, changing of working time by the number of patients at arrival time, increasing of employee. The evaluation of effect were composed of evaluating the number of patient at time, the effect of shift system, the comparison of the number of in and out patients and questionnairing the practice of shift system. In the practice time at 2 shift system First team works 7-15 hours and Second team 12-20 hours. there are no lunch and supper time. At 18-20 hours the number of patients were 25-30. The number of patient a depart were 6-7. The number of out-patient increase in 13% and inpatient increase in 10% before the system. Doctors(100%), employee(94.6%), and patients(86.4%) approved this system. The advantage of this system were utilization of surplus time, lengthen the practice time, even distribution of patients and shortening of waiting time, rapid treatment of emergent patients. The disadvantage of this system were shortage of manpower, not all depart practice, continuity of practice, no lunch and supper time, irregular rounding. At present because of small Demanding on evening clinic, this shift system was economical. To succeed this study more effectively all depart in hospital participate. But because of economical reason it is impossible for hospital to do it. If the government assist the economic loss that all depart participate in this system it is very helpful for hospital to succeed in implementing this system more early.
Purpose: This study was a descriptive research to provide fundamental data in ensuring a high quality of nursing service needed by children's parent according to perception of uncertainty and care satisfaction of them between pediatric outpatient department and emergency room. Methods: For this study, 192 children's parents were questioned in a general hospital located in Busan from August 1 to 31. 2009. The collected data were scored by use of frequencies, $x^2$ test, t-test, AONVA, Pearson's correlation coefficient via SPSS/WIN 17.0. Results: With the compare of characteristics related to children's parents visiting emergency room and pediatric outpatient department, there were statistically significant difference in relation and age of parent, main caregiver, cause of arrival, and waiting time from arrival to procedure. The perception of uncertainty for parent in the emergency room showed significant difference to outpatient department. In nursing service, the highest score was category of professional skill and technic. In addition, overall parents' perceptions on providing information showed lower than any other nursing service. Last but not least, a significant correlation indicated between the perception of uncertainty and satisfaction of nursing service. Conclusion: Efforts to improve parent satisfaction for nursing service are needed to decrease their perception of uncertainty. Providing information and communication by nurses are necessary to improve quality of nursing service.
Purpose: In Korea, trauma is the $3^{rd}$ most common cause of death. The trauma treatment system is divided into pre-hospital and hospital stages. Deaths occurring in the pre-hospital stage are 50% of the total death, and 20% of those are deaths that are preventable. Therefore, the purpose of our study is to calculate the preventable death rates caused by trauma in our current pre-hospital system, to analyze the appropriateness of the treatment of traumatized patients and to draw a conclusions about the problems we have. Methods: The study was done on traumatized patients who expired at the emergency department from January 1, 2005, to December 31, 2009, at the Korea University Medical Centers in Anam, Guro and Ansan. The data on the patients were reviewed retrospectively based on characteristics, conditions on admission and trauma severity. The patient's RTS (revised trauma score) and ISS (injury severity score) was calculated. Preventable death rate was calculated by TRISS (the trauma score-injury severity score). Results: A total of 168 patients were enrolled. All patients were intubated and underwent CPR. Of the total, 72% patients were male, and traffic accidents were the most common form of trauma (52.4%), falls being second (28.6%). Head injury, solitary or multiple, was the most common cause of death (55.4%). Thirty-eight (38, 22.6%) deaths were preventable. The 22.6% preventable death rate consisted of 15.5% potentially preventable and 7.1% definitely preventable deaths. Based on a logistic regression analysis, the relationship between the time intervals until transfusion and imaging and death was statistically significant in the hospital stage. In the pre-hospital stage, transit time from the site of the injury to the hospital showed a significant relationship with the mortality rate. Conclusion: One hundred sixty-eight (168) patients died of trauma at the 3 hospitals of Korea University Medical Center. The TRISS method was used to calculate the preventable death rate, with a result of 22.6%. The only factor that was significant related to the preventable death rate in the pre-hospital stage was the time from injury to hospital arrival, and the time intervals until transfusion and imaging were the two factors that showed significance in the hospital stage. Shortening the time of treatment in the field and transferring the patient to the hospital as quickly as possible is the most important life-saving step in the pre-hospital stage. In the hospital stage, the primary survey, resuscitation and diagnosis should proceed simultaneously.
The purpose of this study was to determine the success rate of air reduction as the primary treatment of intussusception and whether the success of air reduction could be predicted by plain x-ray. The authors reviewed the medical records of 54 consecutive patients diagnosed with intussusception from Jan 2005 to Dec 2007 at the Department of Surgery, Masan Samsung Hospital. The natures of symptoms and findings of plain abdominal radiography performed in the emergency department (ED) were reviewed. Air reduction failed more frequently (26.3 %) in patients who visited ED more than 24 hours after symptom onset (p=0.009). The mean duration of symptom for operated patients was longer than air reduction group (p=0.01). Also, 3/4 of patients having localized distension of small bowel in the left upper quadrant abdomen had unsuccessful air reduction (p=0.002). In conclusion, the time interval from symptom onset to arrival at ED and localized distension of small bowel in the left upper quadrant abdomen significantly increased the failure rate of air reduction.

Purpose: Paraquat, a globally used herbicide, is highly toxic to human beings. Hence, we reviewed some cases of paraquat poisoning in Korea. Methods: We analyzed the clinical and laboratory findings of 50 patients poisoned with paraquat retrospectively. The patients were admitted to the department of internal medicine in the Eumseong KeumWang hospital from January 2008 to December 2008. Results: Among 50 cases of paraquat poisoning, 28 cases were male. Twenty-four cases (48%) were over 60 years old. Fourty-nine patients ingested paraquat on purpose as suicidal attempts, while 1 patient underwent accidental ingestion. Seven patients swallowed less than one mouthful of paraquat, of which 4 patients survived. Eleven patients swallowed two mouthfuls of paraquat, of which 8 patients survived. Thirty-two patients swallowed over three mouthfuls of paraquat and they all died. Thirty-one patients with leukocytosis died. Twenty-one patients with metabolic acidosis died. Increased levels of blood amylase and glucose were related to high mortality, and increased level of blood creatinine was related to severe mortality. Hemoperfusions were accomplished in 27 patients of paraquat poisoning, of which 12 patients survived. Conclusion: Paraquat is a highly toxic herbicide. When patients arrive at the hospital, laboratory findings, urine paraquat concentrations, arrival time, and the amount of paraquat consumed must be considered for treatment plan.
