The purpose of this study is to investigate the effect of balloon blowing exercise on multiple pulmonary function and maximum voluntary ventilation in patients with mild intellectual disabilities in their 20s. 10 people in the experimental group and 10 people in the control group participated in the experiment. The experimental group performed the balloon blowing exercise for 30 minutes a day, and the control group performed the diaphragm breathing exercise for 30 minutes each. The subjects measured voluntary capacity and maximal voluntary ventilation using Fitmate before and after the experiment. Subjects were assessed with Vital capacity(VC) and Maximal voluntary ventilation(MVV) before and after the test and the results were compared with the paired t test. Data analysis was performed with SPSS win 18.0. After the experiment, the experimental group showed higher lung capacity and maximum ventilation than the control group. Through this study, the experimental group increased voluntary capacity and maximum voluntary ventilation more than the control group. It is thought that the quality of life can be improved if we continuously manage the health of intellectuals by developing various breathing exercise programs.

The purpose of this study was to determine whether PNF respiratory exercise increases the vital capacity and maximal voluntary volume of 20s normal adults by 45° leaning sitting position. Twenty normal adults in their 20s were randomly assigned to an experimental group and control group. Over the course of four weeks, the experimental group participated in PNF respiration exercises by 45° leaning position for 30 minutes three per week. And the control group participated in diaphragm respiration exercises by 45° leaning position for 30 minutes three times per week. Subjects were assessed post-test by measurement of vital capacity, maximal voluntary volume. Our findings show that the experimental group had significant improvements in vital capacity, maximal voluntary volume(p<.05). In this study, the experimental group showed more improvement in pulmonary function, which indicates that the PNF respiratory exercise by 45° leaning sitting position is effective at increasing the pulmonary function of normal adults.

The purpose of this study was to examine the effects of a thoracic mobilization exercise using the Kaltenborn on the convergence lung function. The study was conducted on 20 university students in their 20s over a four-week period. The 20 subjects were randomly selective assigned to a Kaltenborn thoracic mobilization exercise group and diaphragm exercise control group. The experimental group performed a Kaltenborn thoracic mobilization exercise for 30 minutes. The control group performed a diaphragmatic breathing exercise for 30 minutes. Each exercise program was performed three times a week for four weeks. When comparing the breathing capacity of the experimental and controls before and after the experiment, the experimental group showed significant changes in TV, IRV. In testing the differences between the experimental and controls in their changes after the experiment, TV, IRV showed a significant change. Based on the results of this study, a thoracic mobilization exercise using the Kaltenborn thoracic mobilization exercise may have positively affected the extrementals lung function. Therefore, if a thoracic mobilization exercise using the Kaltenborn is combined with a respiratory exercise program in the future, it will likely become a more effective treatment technique.

PURPOSE: Recently, the proportion of respiratory diseases has been increasing worldwide, and deaths from respiratory diseases in Korea are increasing. Maintaining a healthy respiratory function is a crucial factor in preventing respiratory diseases. There are various ways to improve respiratory function, such as respiratory muscle and aerobic exercises. In other countries, respiratory muscle exercise is performed using a respiratory resistance mask, but such research is insufficient in Korea. Therefore, this paper proposes a respiratory exercise program using a respiratory resistance mask. METHODS: This study was conducted by dividing healthy adults in their 20s into a treadmill exercise + respiratory resistance mask group and a treadmill exercise group into an experimental group and a control group. The changes in the subject's physical function before and after exercise were confirmed by cardiopulmonary exercise and pulmonary function tests. RESULTS: As a result of the study, the experimental and control groups increased their physical function significantly (p < .05). On the other hand, when the increase rate according to the group was confirmed, the increase rate of the experimental group was higher. CONCLUSION: Based on this study, it is necessary to develop a respiratory exercise program using respiratory exercise tools such as a respiratory resistance mask and provide it easily to various subjects.

Pulmonary function test (PFT) is a test method to determine respiratory disease. In order to obtain accurate PFT results, it is absolutely necessary to induce the inspector and cooperate with the patient. This study was to observe the importance of understanding and posture of the patient in spirometry. In 2016, 110 healthy experimenter performed spirometry; 1) only heard the explanation, 2) watching video and inspector,s demonstration, 3) twisting legs and bending shoulder. FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF were measured by spirometry. FVC, $FEV_1$, $FEV_1/FVC$, $FEF_{25-75%}$, PEF were significantly increased before and after the understanding the test method. There was a significant difference in FVC, $FEV_1$, and PEF in the false posture. Reproducibility was significantly different in the experimenter' comprehension and false posture. This study provides accurate understanding of the patient and correct posture should be maintained during the examination to obtain correct and reproducible results of PFT.

This study applied aquatic and land-based exercises to breast cancer patients for comparative analysis and elucidation of their effects on the rehabilitation of cancer patients. Participants included 40 breast cancer patients who were divided into two groups: 20 participants in the experimental group using aquatic exercise and 20 participants in the control group using land-based exercise. After the addition of aquatic or land-based exercises five times per week for eight weeks, differences in each group's shoulder and pulmonary functions as well as their quality of life were compared and analyzed. The results showed a statistically significant difference (p<.001) for shoulder dysfunction, with the experimental group showing a greater improvement than the comparison group. Statistically significant differences (p<.05 and p<.001, respectively) were also observed for forced vital capacity (FVC) and forced expiratory volume in one second (FEV1), with the experimental group showing greater improvements. Finally, a statistically significant difference (p<.001) was observed for change in the quality of life, with greater improvements in the experimental group than in the control group. The results of further research in this field are expected to indicate the most efficient method for the recovery and management of physical, psychological, and social health impacts of breast cancer on patients. Furthermore, the research aims to provide fundamental resources for breast cancer rehabilitation in South Korea by conducting studies on patients with lung cancer or colorectal cancer and the application of various aquatic exercise methods.

The global outbreak of COVID-19 has underscored the pressing need for robust infection control practices in pulmonary function laboratories (PFL). However, the existing guidelines and regulatory frameworks provided by relevant authorities in the country have revealed certain deficiencies in effectively addressing this significant public health crisis. This study surveyed the infection control regulations, disposable item usage, ventilation facilities, spatial separation, and the configuration of entrance doors in 51 domestic hospital facilities from Oct 1, 2021, to Nov 2, 2021. The survey findings revealed that while there was a relatively satisfactory adherence to airborne, droplet, and contact precautions with adequate awareness and utilization of personal protective equipment, the environmental disinfection practices exhibited a suboptimal performance rate of 39.22% per patient. Depending on the specific survey domains, substantial variations were observed in the utilization of disposable items (81.05%), ventilation systems (45.75%), dedicated testing spaces (80.39%), separation of administrative areas (15.69%), and the installation of automated doors (19.61%). This study not only highlights the paramount importance of infection control in PFLs within domestic medical institutions but also provides foundational data for developing and enhancing standardized guidelines that align with international benchmarks for infection control in these settings.

The purpose of this study was to investigate whether there is a relationship between pulmonary function, serum lipid and pulse pressure, which is a risk factor of cardiovascular disease, in subjects with 109 office workers(51 males and 58 females) be at Seoul, Korea. The mean age of the subjects was $43.44{\pm}7.23$ years old (male $43.44{\pm}7.27$, fenale $49.1{\pm}11.5$). The subjects' height, weight, BMI, systolic and diastolic blood pressures were measured and there was statistical difference between men and women.The mean pulse pressure of the subjects was $47.82{\pm}9.02mmHg$, and the mean of FVC was $84.26{\pm}9.91%$. There was no difference between men and women in both. There was a positive correlation between pulse pressure and systolic blood pressure in males (p<0.01) and females (p<0.01), and FVC and HDL in males were positively correlated (p<0.05). Pulse pressure and %FVC were negatively correlated (r =-0.267, P<0.01). Pulse pressure and %FVC were negatively correlated (r =-0.267, P<0.01). Regression analysis showed that PP was the independent affected %FVC. Therefore, pulse pressure and %FVC may be useful as a predictor of cardiovascular disease in middle-aged subjects with normal, suggest a long-term convergence follow-up is warranted to elucidate the incidence of cardiovascular disease.

This study examined the effect of the respiratory training centered at forced breathing exercise of blowing out a candle on the improvement of adults' respiratory ability, which means the increased muscle strength of body trunk. After the four-week candle-blowing breathing training, the forced vital capacity (FVC) increased statistically significantly (p<.05). The forced expiratory volume in one second (FEV1) did not show a statistically significant difference before and after the four-week intervention(p>.05). The peak expiratory flow rate (PEF) statistically significantly increased after the four-week blowing-out-the-candle training (p<.05). This study examined the relationship between forced breathing training and pulmonary function of healthy adults including FVC, FEV1, and PEF, which means the increased muscle strength of body trunk, by implementing blowing-out-the-candle breathing exercise centered at forced respiratory exercise and obtained significant results. Further studies that use a sample of patients with advanced respiratory system disease for whom physical therapy is absolutely necessary will be required in the future.
