This study evaluated the completeness of emergency medical service (EMS) activity reports. In all, 67,830 cases of normal transfers were statistically analyzed using IBM SPSS Statistics version 22, and statistical significance was set at p <0.5. The 119EMT_2 certificate was omitted in 50,037 (73.8%) cases, followed by time-related items in 1,227 (1.8%) cases. In the primary assessment of vital signs, systolic blood pressure was omitted and erroneous in 1,218 (1.9%) and 1,129 (1.8%) cases, respectively. In the secondary assessment, the completeness of all vital sign items was approximately 70%. As the severity of the patient's condition increased, the errors in the EMS activity report also increased, at a significant level (p=.00). Paramedics must be aware of the importance of completing the activity report.

Objectives: The purpose was to study the market of traditional Korean medical devices and survey, list and number medical devices in traditional Korean medical clinics. Methods: we researched in three ways. 1. We investigated the list of devices regarded as traditional Korean medical devices in 'Report on production, export, and import of medical devices.' 2. We investigated the statistics of medical devices equipped in traditional Korean medical clinics through the website of the Health Insurance Review & Assessment Service. 3. We surveyed medical devices in traditional Korean medical clinics by mail. Results: 1. We could not directly investigate the market for traditional Korean medical devices because they were not categorized as such ('traditional Korean medical devices'). 2. The number of medical devices in traditional Korean medical clinics has increased alongside the increase of traditional Korean medical clinics. 3. Traditional Korean medical clinics hold over 64,962 medical devices and have below 50 percent of traditional Korean medical diagnosis devices. 4. Meridian function testing machines, pulse diagnosis devices, and yangdorak showed ranking of equipment-ratio equal to ranking of insurance fees. Conclusions: Traditional Korean medical device regulations should be enacted following definitive and concrete Korean traditional medical concepts by the Korean traditional medical society.

Attempts have been made to define new classes of distributions that provide more flexibility for modelling skewed data in practice. In this work we define a new extension of the generalized gamma distribution (Stacy, The Annals of Mathematical Statistics, 33, 1187-1192, 1962) for Marshall-Olkin generalized gamma (MOGG) distribution, based on the generator pioneered by Marshall and Olkin (Biometrika, 84, 641-652, 1997). This new lifetime model is very flexible including twenty one special models. The main advantage of the new family relies on the fact that practitioners will have a quite flexible distribution to fit real data from several fields, such as engineering, hydrology and survival analysis. Further, we also define a MOGG mixture model, a modification of the MOGG distribution for analyzing lifetime data in presence of cure fraction. This proposed model can be seen as a model of competing causes, where the parameter associated with the Marshall-Olkin distribution controls the activation mechanism of the latent risks (Cooner et al., Statistical Methods in Medical Research, 15, 307-324, 2006). The asymptotic properties of the maximum likelihood estimation approach of the parameters of the model are evaluated by means of simulation studies. The proposed distribution is fitted to two real data sets, one arising from measuring the strength of fibers and the other on melanoma data.

Background : The current medical statistics used in clinical research are the results of Fisher's significance test and the Neyman-Pearson hypothesis test, which were combined by psychologists. Also, in the philosophical background, it is related to Popper's falsificationism based hypothesis-deductive method and reduction to absurdity. Objectives : This study was designed to find complementary and alternative methods of null hypothesis and alternative hypothesis used for the clinical research methodology of Korean medicine otolaryngology. Methods : The body of this paper was divided into seven part. These are historical background, hypothesis test, hypothesis test method used in the design of clinical study, falsificationism and reduction to absurdity, problem and alternative method of the Neyman-Pearson hypothesis test, diagnosis example of sinusitis differentiation syndromes by Bayesian statistics. Through this process, we found out problems of frequentist statistics and suggested alternative methods. Result & Conclusion : As a solution to the problems of the null hypothesis and the alternative hypothesis, there are effects size, confidence interval, Bayesian statistics and Lakatos methodology of scientific research programmes.

Objective: This study was conducted for the nationwide statistical survey of poison exposure to provide the rationale for establishing and developing the poison control center (PCC) in Korea. Design: Study group for Korea PCC in National Medical Center reviewed the medical literature on poison exposure of Korea from death reports of National Statistical Office (NSO), the toxic exposure statistics from the report of National Health Insurance Corporation (NHIC), and poison related data from 119 ambulance services (FD) for the purpose of obtaining the poison and its related data. We also conducted questionnaire from the expert who work in emergency medicine department at the designated 320 emergency medical centers in Korea for the preparedness and acknowledgement about necessity of PCC and their need for that. Results: We reviewed the reliable data from the death report of NSO, poison exposure data from NHIC, and running report from FD. Poisoning death occured at home ($36.7\%$) and hospital ($46.3\%$). Poisoning are more common in rural area than the city area. Patients were seen more frequently in the local clinics than in any hospital. The drugs ($45.7\%$) and pesticide ($18.1\%$) are common poison. Common place to poison exposure were residential area ($39.9\%$), industry ($9\%$). mass residential area ($7\%$). and farm ($6\%$). The education level were primary school ($33.2\%$), high school ($23.7\%$), and middle schol ($21.3\%$) in order. We have to provide the poison guideline for lay public to understand easily, and for medical experts. The medical facilities need to be invested and have more interest for toxicology. All medical staff who work in the designated emergency medical center want PCC to establish. They want to have poison information from hospital ($91.3\%$), regional poison information center ($45.0\%$), regional poison control center ($52.5\%$), nationwide poison information center ($48.8\%$), nationwide poison control center ($46.25\%$), as a role of poison control center. They also want that pcc have poison epidemiologic study and statstics, training program for the experts, registration of rare case of posion on website, reflection of policies to activities for antidote production etc., speedy consultation system for poison analysis, public education, establishment of both regional and national pee, etc. Conclusion: Poison center must be established to provide poison information for all the public and medical experitise, focusing rural area and private clinic, to detoxify, to reduce the cost, time, morbity, and mortality through the whole country.

Objective : To investigate the therapeutic effect of manual acupuncture at Siguan (four gates, bilateral LI4 and LR3) on suppression of gastrointestinal motility. Methods : A single blind, randomized, sham-acupuncture controlled, crossover study was conducted. Twenty healthy male subjects were admitted at hospital, and gastrointestinal motility suppression was induced by loperamide administration. Just after intake of 20 radio-markers, four gates or sham acupoint treatments were administered every 12 hours, 4 times over 48 hours. Gastrointestinal motility was evaluated by radiographic distribution of the radiomarkers at stomach or ileum, ascending, transverse, descending colon, sigmoid/rectum, and outside body at serial time points (0, 6, 12, 24, and 48 h). Results : Four gates acupuncture activated gastrointestinal movement as evidenced by significantly changed distributionof radio-makers at 6, 12, and 48 hours (P < 0.0001, P = 0.001, and P = 0.03, respectively) in Cochran-Mantel-Haenszel statistics. No serious adverse events occurred in either group. Conclusions : This study showed a scientific clinical relevance of four gates acupuncture to gastrointestinal disorders.

This study analyzed current prehospital emergency care for severe trauma patients administered by different number of 119 EMS (emergency medical services) teams. Out of 1,067 severe trauma patients transferred by 119 EMS teams in J province from January 1st to December 31st 2015, 438 were evaluated in this study. IBM SPSS Statistics 21.0 was used to analyze collected data. The number of patients with severe trauma during the period of study was higher in male with two and three ambulance crews of 119 EMS teams with 242 patients (70.6%) and 66 patients (69.5%) respectively. The percentage of transfers made to local emergency medical centers was highest in those two groups, being 44.0% (151 patients) and 49.5% (47 patients), respectively. Total time spent at the scene did not differ between ambulance crews of two and three, nor did the frequency of practicing advanced airway management and IV (intravenous) cannulation, or the success rate of IV cannulation (p=0.253, p=0.362, p=1.000). Overall, the results indicated that merely increasing the number of paramedics does not improve the quality of prehospital care for severe trauma patients. Measures such as securing professional paramedics, simplifying direct medical oversights, activating indirect medical oversights, and expanding the legally allowed work scope are required.

Objectives: This study aims to identify the factors associated with regular medical services utilization of chronic disease patients. Methods: The research selected 4,489 adults aged over 30, diagnosed with hypertension, diabetes, hyperlipidemia, hypercholesterolemia, from the Korea health panel. We analyzed states of regular medical service utilization using descriptive statistics. Multiple regression analysis was used to examine the main factors associated with regular medical services utilization in chronic disease patients. Results: In terms of socio-demographic factors, gender, age, marital status, education level, employment, household income and disability were significantly different between hypertension, diabetes, hyperlipidemia and hypercholesterolemia. Among health status and behavioral factors, number of chronic diseases, subjective health status, smoking, high risk drinking, regular meals, physical activity, obesity were significantly different. From the multiple logistic regression analysis, age, number of chronic diseases, obesity, type of chronic diseases were associated with regular medical services utilization. Conclusions: It is necessary to develop effective health education programs and individualized approach to improve continuous management in chronic diseases patients.
