The study was done to provide basic data of medical quality evaluation after developing the comorbidity disease mortality measurement modeled on the severity-adjustment method of AMI. This study analyzed 699,701 cases of Hospital Discharge Injury Data of 2005 and 2008, provided by the Korea Centers for Disease Control and Prevention. We used logistic regression to compare the risk-adjustment model of the Charlson Comorbidity Index with the predictability and compatibility of our severity score model that is newly developed for calibration. The models severity method included age, sex, hospitalization path, PCI presence, CABG, and 12 variables of the comorbidity disease. Predictability of the newly developed severity models, which has statistical C level of 0.796(95%CI=0.771-0.821) is higher than Charlson Comorbidity Index. This proves that there are differences of mortality, prevalence rate by method of mortality model calibration. In the future, this study outcome should be utilized more to achieve an improvement of medical quality evaluation, and also models will be developed that are considered for clinical significance and statistical compatibility.

This paper proposes renovation guidelines for impaired persons' facilities in Chungcheongnam-Do by reviewing the conditions of the facilities based on the standard and deinstitutionalization trends in foreign facilities. The facilities were located far from the downtown of cities. Therefore, education and adaptation programs are necessary for these people to return to society. Recombining the rooms for a living room-oriented unit considering the structure system of the facilities allows good adaptation to home-based living conditions for impaired people. The area per person will be increases by renovations to a living room-oriented unit that makes upgrades to near foreign standards, such as The USA and The UK.

This review was conducted to identify the research trends in music intervention studies with elderly patients with dementia. Korean- and English-written studies on music intervention for this population were searched and analyzed. Seventeen studies were included in the final analysis. The results showed that behavioral and psychological symptoms were the main dependent variables. In terms of the type of music intervention employed, interventions requiring the patient's active participation in producing music were more common than interventions that required the patient to only listen to music. The majority of studies provided live music, selected music that was familiar to and preferred by the patient, and utilized rhythm-based performance activities. In the studies using active music production as the intervention, the participants were asked to express the emotions evoked by group instrument playing or singing along with music, which doesn't reflect the functional limitations (e.g., cognitive impairment) of elderly patients with moderate to severe dementia. The results of this review point to the need in the field to develop music intervention programs for the elderly with moderate to severe dementia that meaningfully engage these patients in music-related behaviors that target their specific symptomology.

This study examined the intensity of the association of factors affecting major burns by statistical analysis for patients injured by the release of chemical hazards. A total of 446 patients were evaluated as chemical injury patients, who had visited the emergency room from 1/Jan/2010 to 31/Dec/2014. The major burn was used as a dependent variable representing the severity of chemical injury. A chi-square test (CST) and binary logistic regression test (BLRA) were used as the statistical analysis method for determining the association between major burns and the independent variables. In CST, female and their presence at an incident scene, multiple site injury were associated with major burn (p<0.05). In BLRA, the presence at an incident scene and spills (comparing explosion), discharge (comparing admission) were associated with major burns (p<0.05). In this study, the presence at an incident scene was the most significant factor concerning major burns. Furthermore, gender and injury number, exposure mechanism (spill comparing explosion), and disposition (discharge comparing admission) were also associated with major burns.

The purpose of this study was to determine whether the results of KTAS(Korean Triage and Acuity Scale) triage classifier differ according to the occupations. We analyzed a total of 10,960,359 cases of data sent to the NEDIS from January 1st, 2016 to December 31th, 2017. The triage classifier were MD(Medical Doctor), R(Resident), INT(Intern), GP(General Practitioner), RN(Registered Nurses) and EMT(Emergency Medical Technician). The consistency between the initial triage and final triage results was the highest GP(98.9%) and the lowest INT(80.2%). The results of over-triage classification was the lowest by GP(0.6%) and the highest for INT(16.0%). Also, the results of under-triage classification was the lowest by MD, EMT(0.4%) and the highest for INT(3.8%). The results of KTAS triage classifier significantly differ from according to the occupations(p<0.001). Triage classification should not differ from according to occupations and skill. It is necessary to strengthen the classifier's capacity for accurate triage classifications.

This retrospective study investigates the accuracy of triage procedures for pediatric patients in emergency departments (EDs) using the Korean Triage and Acuity Scale (KTAS). The study includes 250 randomly selected initial nursing records and clinical outcomes of pediatric patients who visited one regional ED or a local ED from October 2016 to September 2017. The collected data were analyzed by a qualified expert to determine the true triage score. The accuracy of triage was defined as the agreement between the triage score of the emergency nurses (ENs) and the true triage score as determined by the expert. Based on expert comments, the cause of the triage error was analyzed and the KTAS score was compared with the discharge, length of stay (LOS), and medical cost. The results showed that the degree of agreement in the triage score between the experts and the ENs was excellent (weighted kappa=0.77). Among the causes of triage discordance, the most frequent was the incorrect application of vital signs to the KTAS algorithm criteria (n=13). Patients with high severity KTAS levels 1 and 2 were discharged less often (${\chi}=43.25$, p<0.001). There were significant differences in the length of stay (F=12.39, p<0.001) and cost (F=11.78, p<0.001) between KTAS scores when adjusting for age. The results of this study indicate that KTAS is highly accurate in EDs. Hence, the newly developed triage tool is becoming well established in Korea.

This study was conducted to develop a customized severity-adjustment method and to evaluate their validity for acute myocardial infarction(AMI) patients to complement the limitations of the existing severity-adjustment method for comorbidities. For this purpose, the subjects of KCD-7 code I20.0 ~ I20.9, which is the main diagnosis of acute myocardial infarction were extracted using the Korean National Hospital Discharge In-depth Injury survey data from 2006 to 2015. Three tools were used for severity-adjustment method of comorbidities : CCI (charlson comorbidity index), ECI (Elixhauser comorbidity index) and the newly proposed CCS (Clinical Classification Software). The results showed that CCS was the best tool for the severity correction, and that support vector machine model was the most predictable. Therefore, we propose the use of the customized method of severity correction and machine learning techniques from this study for the future research on severity adjustment such as assessment of results of medical service.

The aim of this retrospective study was to compare risk factors between men and women through secondary data of nursing information and medical records according to the severity classification in patients of 340 men and 221 women with coronary artery disease(CAD) who were admitted for the first time at a general hospital and underwent first coronary artery angiography. Consequently, men presented with risk factors such as age(p=.004), total cholesterol(p=.040), triglycerides(p=.049), HbA1c(p<.001), smoking(p<.001), alcohol consumption(p=.002) and comorbidities(p=.036) that showed statistically significant differences. Among women, age(p=.002) and comorbidities (p=.018) were the only factors that showed significant differences. Significant risk factors influencing the classification of CAD severity in men were total cholesterol (OR 0.97, 95% CI 0.96-1.00, p=.014) in 1VD, alcohol consumption (OR 52.47, 95% CI 2.99-91.95, p=.007)in 2VD, and total cholesterol in the 3VD(OR 0.98, 95% CI 0.95-0.98, p=.026). A significant risk factor affecting the classification of CAD severity in women was comorbidity (OR 0.30, 95% CI 0.11-0.82, p=.020) in the 3VD. This study identified the importance of nursing care for male CAD patients, such as smoking cessation and quitting drinking, blood sugar control, cholesterol, and accompanying disease management, and provided evidence of individually tailored nursing care.

우리가 다른 이들과 만나 대화하는 것은 극히 평범한 일이다. 하지만 대화뿐만이 아니라 의사소통마저도 힘들어하는 이들이 있다. 이들은 언어 장애를 가진 이들이다. 언어 장애에는 태어나면서부터 장애를 가지는 선천적 장애와 사고와 질병으로 인한 후천적 장애가 있다. 그 중 후천적 장애는 언어장애와 더불어 신체적 장애를 가진 이들이 있다. 이들을 본 논문에서는 중증 언어 장애인이라고 분류하였다. 중증 언어 장애인의 장애정도를 크게 글자 표현이 불가능한 상태로부터 4가지 단계로 나뉠 수 있다. 글자 표현이 불가능하지만 개체 선택이 가능한 1단계, 손 혹은 발을 이용하여 가부 결정만 가능한 2단계, 지체를 이용하여 표현이 불가능한 3단계, 그리고 마지막 4단계가 3단계의 표현마저도 불가능하여 의사소통이 전혀 불가능한 상태이다. 사고로 인한 후천적 장애인 경우 위의 4가지 단계중 하나의 단계에서 머물러 있지만, 루게릭병과 같은 병은 위의 4가지 단계를 몇 년에 걸쳐서 진행되기 때문에 일반적인 장비로써는 이 들과의 의사소통이 불가능하다. 본 논문에서는 위의 1,2,3단계의 중증 언어 장애인을 대상으로 그들이 의사소통을 정확하고 신속하게 전달하기 위해서 어떠한 인터페이스를 사용하는 것이 효과적인 방법에 대해 논해보고, 향후 발전될 방향에 대해서 그 방향을 제시하였다.

신체 움직임이 자유롭지 못한 중증 장애인의 경우 환경제어장치를 사용하면 일상생활 보조가 가능해지므로 활용 효과가 매우 크다. 그러나 현재 국내에서 개발되는 제품은 정상인을 위한 홈오토메이션이 대부분이고, 장애인을 위한 환경제어장치의 경우에도 입력 매체에 따라 대상 사용자가 제한되는 문제점이 있었다. 따라서 본 논문에서는 기존의 입력 장치 사용에 제한이 있었던 중증 장애인들도 사용가능하도록 1-채널 생체신호(뇌파 및 얼굴 근전도) 계측 시스템 및 환경제어장치를 개발하였다. 향후 개발된 시스템은 중증 장애인의 일상생활 체험관에 구축하고 장애인의 사용성 평가를 통해 그 효과를 입증하고자 한다.
