Purpose: Pneumoconiosis is a chronic lung disease in which the lungs become hardened due to the accumulation of fine mineral dust that has been breathed in at industrial sites. The lungs are unable to function properly, resulting in complications of several respiratory diseases. Methods: The subjects were 36 elderly adults (pneumoconiosis patients 18, healthy elderly 18) over the age of 65 years. The respiratory function was assessed using a spirometer to measure forced vital capacity (FVC), first second of forced expiration (FEV1), FEV1/FVC, and peak expiratory flow n(PEF). The static balance function test was determined by the center of mass (COM), ankle angle range, hip angle range, sway parameters, and reciprocal compensatory index (RCI). Cognitive function was measured by applying MoCA-k. Results: Comparison of respiration functions between the two groups showed statistically significant differences in FVC, FEV1, FEV1/FVC, and PEFs (p<0.05). Cognitive abilities showed statistically significant differences due to higher cognitive skills in the control group as compared to the patient group (p<0.05). Most results of the static balance capability measurements showed statistically significant differences between the groups (p<0.05). However, no statistically significant differences were obtained for COM AP Range, Angle AP Range, RCI ML Range, and AP Range (p>0.05). Conclusion: The results of the current study indicate that patients suffering from pneumoconiosis have less cognitive ability and balance function as compared to healthy elderly people. Therefore, we expect an improvement in the balance ability and cognitive function through systematic management and strengthening lung function training to improve the quality of life of pneumoconiosis patients.

Background: Proper education regarding inhaler usage and optimal management of chronic obstructive pulmonary disease (COPD) is essential for effectively treating patients with COPD. This study was conducted to evaluate the effects of a comprehensive education program including inhaler training and COPD management. Methods: We enlisted 127 patients with COPD on an outpatient basis at 43 private clinics in Korea. The patients were educated on inhaler usage and disease management for three visits across 2 weeks. Physicians and patients were administered a COPD assessment test (CAT) and questionnaires about the correct usage of inhalers and management of COPD before commencement of this program and after their third visit. Results: The outcomes of 127 COPD patients were analyzed. CAT scores ($19.6{\pm}12.5$ vs. $15.1{\pm}12.3$) improved significantly after this program (p<0.05). Patients with improved CAT scores of 4 points or more had a better understanding of COPD management and the correct technique for using inhalers than those who did not have improved CAT scores (p<0.05). Conclusion: A comprehensive education program including inhaler training and COPD management at a primary care setting improved CAT scores and led to patients' better understanding of COPD management.

Purpose: The purpose of this study was to evaluate the effectiveness of pulmonary rehabilitation on lung function and fatigue in persons with chronic obstructive pulmonary disease (COPD). Methods: Thirty one persons with COPD participated in this study. Four groups were allocated as follows: experimental group 1 (under 10 years of the post-disease period), control group 1 (under 10 years of the post-disease period), experimental group 2 (over 10 years of the post-disease period), and control group 2 (over 10 years of the post-disease period). Results: Forced expired volume in one second (FEV1) % pred and lactic acid showed improvement in experimental group 1 and experimental group 2 after training. Control group 1 and control group 2 did not show improvement of FEV1% pred and lactic acid after training. However, FEV1% pred and lactic acid in experimental group 1 were not significantly different, compared with the experimental group. Conclusion: Results of our study suggest that implementation of a pulmonary rehabilitation program resulted in improvement of lung function and fatigue in persons with COPD not related to the post-disease period.

The diagnosis of human hydatidosis is primarily made using radiological and serological methods. Radiological methods are generally of low specificity and serological methods lack sensitivity, especially for pulmonary disease. In this study the capabilities of a new rapid test, the hydatid antigen dot immunobinding assay (HA-DIA), which was developed for the diagnosis of pulmonary hydatidosis, were studied and compared with another immunodiagnostic method, indirect hemagglutination (IHA). The study subjects included 18 patients, 9 women, 9 men; range 7 to 63 years; mean 30 years, with surgically proven pulmonary hydatidosis, a control group comprised of 14 patients; viral respiratory infections (1), cirrhosis (2), connective tissue disease (2), taeniasis (3), and 6 healthy donors. We found that the HA-DIA test had a sensitivity of $67\%$ and specificity of $100\%$, and that the IHA test had a sensitivity of $50\%$ and specificity of $100\%$. We conclude that HA-DIA is a simple, rapid, low cost assay that does not require instrumentation and has a higher sensitivity than IHA for the diagnosis of pulmonary hydatidosis.

Purpose: This study was undertaken to identify the effect of amateur wind musical performance and choir activity on pulmonary function, and to determine the usefulness as a respiration training program by measuring the pulmonary functions of subjects. Methods: A total of 90 subjects (wind instrument players group=30, choir members group=30, control group=30) participated in the experiment. Pulmonary function test (FVC, FEV₁, FEV₁/FVC ratio, MVV, SVC, PEF, FEF 25-75%, IRV, ERV) was conducted using a spirometer (CardioTouch 3000S, Bionet, Seoul, Republic of Korea). Each factor was measured 3 times to meet the American Thoracic Society criteria, and the highest value was used in the analysis. Results: Comparing pulmonary function between the amateur wind instrument players (WP), amateur choir members (CH), and control (CG) groups revealed significant differences in FEV₁, FVC, FEV₁/FVC, and ERV (p<0.05). Highest values were obtained in the WP group. Significant differences were obtained for various factors in the multiple regression analysis of practice year (PY), practice time per week (PTPW), and exercise time per week (ETPW): FEV₁ and FVC in PY, FEV₁/FVC in PTPW, and FEV₁/FVC, MVV, PEF, and FEF (25-75%) in ETPW. Conclusion: Amateur wind instrument performance effectively improves lung function and is useful as a breathing training program for preventing debilitation and improving respiratory function.

Purpose: The aim of this study was to develop a simulation-based High Flow Nasal Cannula Oxygen Therapy training program based on NLN/ISF to identify the effect on knowledge, clinical performance, and educational satisfaction compared to a group who had traditional High Flow Nasal Cannula Oxygen Therapy training after applying it to clinical nurses. Methods: 31 experimental groups and 33 control groups were conducted from August 2019 to September 2019 for inexperienced nurses over 4 months to 5 years with no experience using high-flow oxygen therapy. Educational programs were developed in scenarios according to Airvo2 and Optiflow, such as facilitator, participant, educational condition, design, characteristics, and educational outcomes. The education application was conducted in advanced for knowledge and clinical performance ability after watching therapy video. Since then, a total of 90 minutes have been conducted for respiratory failure theory training, airvo2 and optiflow simulation training, and debriefing. After applying the education, the medical institution measured nurses' knowledge, clinical performance, and education satisfaction. Data were analyzed using descriptive statistics, with the SPSS/WIN 22.0 program. Results: Both knowledge and educational satisfaction were higher in the experimental group than in the control group (t=-14.09, p<.001), (t=-12.99, p<.001). The clinical performance for both use of Optiflow and Airvo2 were higher in the experimental group than in the control group (t=-11.39, p<.001), (t=-11.38, p<.001). Conclusion: Results showed that the simulation-based High Flow Nasal Cannula Oxygen Therapy training was effective with the experimental group having increased scores for every area of this study.
