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.

Pneumonia is one of the important diseases in commercial pig. In order to delineate the relationships with pneumonia and productions traits, five different economic traits including carcass weight(CW), backfat thickness(BF), meat quality(MQ), carcass characteristics(CC) and pork belly thickness(PB) were measured in 6,362 commercial pigs. Significant differences were observed in all the traits with pneumonia(P<0.01). Carcass weight and backfat thickness decreased significantly as the symptom of pneumonia was severed (P<0.01). Also, when the pneumonia was severed, the carcass characteristics and meat quality became worse compared with normal unaffected animals(P<0.01). In case of pork belly thickness, the significant decrease was observed in pneumonia infected animals compared with normal animals(P<0.01). Based on this study, the pneumonia infection affects most of the important economic traits in pigs and it is ultimately needed to pay more attention to prevent this disease.

Mycoplasma pneumoniae (M. pneumoniae) is the leading cause of pneumonia in older children and young adults. Normally, it does not progress to a condition requiring hospitalization but improves spontaneously or has a mild clinical course. We report two cases of M. pneumoniae pneumonia with different clinical manifestations from the normal course. The patients were young healthy individuals. The diagnoses were made by serology. However, it could not be determined beforehand that they had M. pneumoniae pneumonia. Based on the empirical treatment strategy of severe community acquired pneumonia, the patients were treated with broad-spectrum antibiotics including cephalosporin, quinolone and macrolide. After administering the antibiotics, they showed a gradually favorable clinical course and recovered without residual complications. A M. pneumoniae infection should be considered as a cause of severe community acquired pneumonia, and empirical treatment targeting this organism might be helpful in treating patients with the severe manifestation.

This study was conducted to develop a severity-adjusted LOS(Length of Stay) model for knee replacement patients and identify factors that can influence the LOS by using the Korean National Hospital Discharge in-depth Injury Survey data. The comorbidity scoring systems and data-mining methods were used to design a severity-adjusted LOS model which covered 4,102 knee replacement patients. In this study, a decision tree model using CCS comorbidity scoring index was chosen for the final model that produced superior results. Factors such as presence of arthritis, patient sex and admission route etc. influenced patient length of stay. And there was a statistically significant difference between real LOS and adjusted LOS resulted from health-insurance type, bed size, and hospital location. Therefore the policy alternative on excessive medical utilization is needed to reduce variation in length of hospital stay in patients who undergo knee replacement.

The purpose of this study is to compare relationship among pulmonary function, dyspnea, and health-related quality of life in patients with COPD. The instruments were used FEV1(%), the Baseline Dyspnea Index(BDI), the Medical Research Council Scale(MRCS), and the St. George's respiratory questionnaire(SGRQ). Dyspnea of patients with moderate and severe stage were deeper than one of patients with mild stage(BDI F=5.452, p=.007; MRCS F=4.925, p=.011). And health-related quality of life of patients with severe stage were poorer than one of patients with mild stage(F=3.778, p=.030). There were significant, but weak, correlations between scores of the BDI(r=.471), the MRCS(r=-.403), the SGRQ(r=-.476) and FEV1. There were strong correlations between scores of the BDI(r=-.752), the MRCS(r=.645) and the SGRQ. And FEV1 didn't correlated with the BDI, the MRCS, and the SGRQ scores in patient of moderate stage and severe stage. But there were also strong correlations between the BDI(r=-.719), the MRCS(r=.607) and the SGRQ in patient of moderate stage and severe stage. Specially, correlation between the BDI and the SGRQ were higher than one between the MRCS and the SGRQ. In conclusion, Using the BDI for evaluation of the subjective dyspnea with objective pulmonary functional test in patients with COPD, it will able to grasp the health-related quality of life.

The purpose of this study is to explore the improvement method of the emergency safety system as a social protection scheme for the elderly living alone with severe disabilities. The study was conducted by randomly choosing three regions in the metropolitan area (Jongno-gu, Seoul), the small-medium city (Yongin-si, Gyeonggi-do) and the rural area (Geochang-gun, Gyeongsangnam-do) among 17 cities and counties nationwide. The study method is based on the interview form of the structured questionnaires with city officials, county officials, and center operators. According to the results of the interview analysis, it was recognized that there was a need for an emergency safety system for the elderly living alone with severe disabilities. In spite of this necessity, there were problems about publicity for the discovery of victims of the blind spot in welfare, about inconvenience due to frequent malfunctions of the emergency equipment, about insufficient awareness of the security of the emergency officials and about supply and demand of manpower for 24-hour monitoring service. In order to improve the effective operation of the emergency safety system, it was the most urgent issue to formulate the legislation for responding to the crisis management of the vulnerable. A suggestion of this study is to build a safety system in which one-stop service is provided for the realization of compact welfare through the establishment of a MOU for linkage with community organizations, the full inspection of emergency equipment to solve safety equipment malfunction problems and the manpower supplement for 24-hour monitoring.

Purpose The purpose of this study was to describe the clinical features and chest computed tomography (CT) findings of coronavirus disease 2019 (COVID-19) pneumonia. Materials and Methods An Institutional Review Board-approved retrospective review was performed for 51 laboratory-confirmed COVID-19 pneumonia patients. Patients were divided into two groups depending on their clinical status: mild and severe. Clinical characteristics and chest CT findings were compared between the two groups. Results Among the 51 patients (22 men, 29 women; mean age, 56.5 ± 16 years; range, 22-88 years), 37 (72.5%) were in the mild group and 14 (27.5%) were in the severe group. The patients in the severe group (68.7 ± 12.5 years) were older than the patients in the mild group (51.8 ± 14.9 years, p < 0.001). Premorbid conditions and decreased lymphocyte counts were more often observed in the severe group than in the mild group (71% vs. 41%, p = 0.049 and 86% vs. 32%, p = 0.001, respectively). On chest CT, most patients exhibited a mixed ground-glass opacification (GGO) with consolidation (76%) or a GGO (22%) pattern. The majority of lesions were predominantly bilateral in the lower lung with a posterior, peripheral distribution. The patients in the severe group had higher severity scores than those in the mild group. Conclusion Patients with laboratory-confirmed COVID-19 pneumonia have typical chest CT findings that provide important information regarding expected disease severity.

Background: The need to study music intervention for adolescents with severe developmental disabilities who engage in aggressive behavior. Purpose: This study aims to examine the researcher's experience in creating a music intervention environment when adolescents with severe developmental disabilities engage in aggressive behavior to avoid tasks. Method: Among the qualitative research methods, the researcher's experiences were explored through autoethnography. Collect a variety of empirical data on the research topic, the experience was analyzed according to the thematic analysis method of Braun and Clarke(2006). Results: As a result of data analysis, 31 codes, 9 sub-topics, and 3 super-topics were derived. Three superordinate themes were derived according to the nature of the environment: "Musical environment to reduce task resistance," "Physical environment that provides stability and comfort" and "Interpersonal environment with trust and warmth." Conclusion: In order to prevent and alleviate aggressive behavior in adolescents with severe developmental disabilities, it is important to create an environment tailored to them, so an ecological approach is necessary in music intervention. Although this is only a partial study, it provides information to therapists preparing for music intervention for adolescents with severe developmental disabilities and is meaningful as basic data on future intervention plans and coping strategies.
