  • Purpose: The purpose of the present study is to examine risk factors for unawareness of obstructive airflow limitation among adults with chronic obstructive pulmonary disease. Methods: Secondary data analysis was performed with the data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES; 2013-2014). The data were analyzed with the IBM SPSS 22.0 version using frequency, percentage, odds ratio, and logistic regression. Results: Ninety-eight percent of subject with a pulmonary function test score of $FEV_1/FVC$<0.7 (N=833) did not recognize that their lung function was impaired. The heavy drink, absence of tuberculosis or asthma diagnosis, and no symptom of expelling phlegm were identified as major risk factors for unawareness of airflow limitation. Conclusion: In order to increase awareness of airflow limitation and to prevent the worsening of the condition, the pulmonary function screening test should be provided to community residents including those who do not show symptoms of respiratory illness.

  • The purpose of this study is to compare and analyze the air infections in middle and small hospitals with the facilities of large national hospitals that have air-borne infection isolation (AII) wards through actual condition investigation and airflow analysis simulation (CFD) and to provide basic data for prevention. The method and scope of the study are as follows. First, through literature review, data related to prevention of infection spread in domestic medical institutions were investigated. Second, we conducted a survey on the status of isolation facilities to prevent the spread of infectious diseases in large hospitals and small and medium - sized clinics in Korea. Third, airflow analysis simulation (CFD) was carried out using the isolation ward of the nationally designated inpatient ward and the data of the plane and facility system of the small clinic. As a result of the study, it is found that regulations applicable to small and medium-sized clinics are insufficient. In addition, the simulation results show that the infectious disease virus is likely to spread to other patients in the hospital.
