Purpose : The aim of this study was to investigate the change of the respiratory function of chronic low back pain patients after the thoracic manipulation and the trunk stability exercise on chronic low back pain patients. Methods : For this study, the group of the experiment was consisted of 44 patients suffering from the low back pain chronically. The participants were divided into two groups: the control group, which was assigned for core stabilization exercise (CSE), and the experimental group, which was randomly assigned for core stabilization exercise after thoracic manipulation (CSE+TM). Both groups carried out each assigned treatment on three times a week for 8 weeks. To study the change related to measurement variable from each test groups before and after intervention, paired t-test was performed. Further, the statistics for an intergroup comparison was analyzed by covariance analysis, ANCOVA. The measurement was conducted by the respiratory function, the respiratory function was measured by forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁). Results : As a result, forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) showed significant differences not only by each groups but also between those groups before and after the test. Conclusion : In conclusion, both experiments, the core stabilization exercise and the core stabilization exercise conducted after thoracic manipulation, on chronic low back pain patients resulted in the significant level of difference in the respiratory function. This result indicates that the thoracic manipulation is an efficient treatment for improving the respiratory function for chronic low back pain patients.

Objectives: The Indonesian Ministry of Health launched isoniazid preventive therapy (IPT) in 2016, with general practitioners (GPs) at the frontline of this program. However, the extent to which GPs have internalized this program remains uncertain. The aim of this study was to identify the knowledge and attitudes of GPs towards the IPT program in Indonesia. Methods: This study used an online, self-administered questionnaire distributed via e-mail and social messaging services. A logistic regression model was employed to identify the explanatory variables influencing the level of knowledge and attitudes toward IPT among GPs in Indonesia. An empirical analysis was conducted separately for each response variable (knowledge and attitudes). Results: Of the 418 respondents, 128 (30.6%) had a good knowledge of IPT. Working at a public hospital was the only variable associated with good knowledge, with an adjusted odds ratio (aOR) of 1.69 (95% confidence interval [CI], 1.02 to 2.81). Furthermore, 279 respondents (66.7%) had favorable attitudes toward IPT. In the adjusted logistic regression analysis, good knowledge (aOR, 0.55; 95% CI, 0.34 to 0.89), 1-5 years of work experience (aOR, 2.09; 95% CI, 1.21 to 3.60), and having experienced IPT training (aOR, 0.48; 95% CI, 0.25 to 0.93), were significantly associated with favorable attitudes. Conclusions: In general, GPs in Indonesia had favorable attitudes toward IPT. However, their knowledge of IPT was limited. GPs are an essential element of the IPT program in the country, and therefore, adequate information dissemination to improve their understanding is critical for the long-term viability and quality of the IPT program in Indonesia.

Purpose : This study aims to evaluate the effectiveness of a sea breeze walking program by analyzing the metabolic disease-related, immune-inflammation-related, and respiratory health-related variables of the test subjects associated with improved respiratory health. Methods : In the experiment, 30 patients with metabolic diseases were divided into an experimental group (n=15) and a control group (n=15). The experimental group walked on the Namparang-gil, Geoje trail, while the control group walked on the Hoeya-cheon, Yangsan trail. Both groups participated in the same walking program for two hours, twice a week for four weeks. Thereafter, the metabolic disease-related, immune inflammation-related, and respiratory health-related variables were measured and compared between the two groups. Results : After the four-week sea breeze walking program, in terms of changes in the metabolic disease-related variable, a statistically significant interactive effect was found in waist circumference (p<.001). The experimental group showed a significant decrease in waist circumference after the program. After the four-week sea breeze walking program, the control group showed a statistically higher increase in lactic acid (p.<05), whereas the experimental group exhibited a decrease in lactic acid. For the respiratory health-related variables, no statistically significant differences were found after the sea breeze walking program. However, the experimental group showed an increase in FEV1,while the control group showed a decrease in FEV1. For the maximum oxygen intake, no statistically significant interactive differences were found but there was a statistically significant effect in time (p<.05). The two groups exhibited an increase in maximum oxygen intake. Conclusion : After the sea breeze walking program, positive physical changes were observed in the metabolic disease-related and immune inflammation-related variables.

This study was conducted to understand the level of compliance and influencing factors to respiratory infection prevention among the college students who experienced the COVID-19 pandemic. An online survey was conducted on 200 college students from December 15, 2023 to January 5, 2024, and the data of 199 people who responded faithfully were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression through SPSS 18.0. According to the result, the compliance level of respiratory infection prevention was 32.95±6.05 points on average out of 48 points. The general characteristics, which showed differences in the compliance level of respiratory infection prevention, and the characteristics related to respiratory infections were identified to be major (t=-2.59, p=.010), education on respiratory infection prevention (t=1.99, p=.048), influenza vaccination of the year (t=-2.10, p=.037), COVID-19 vaccination of the year (t=3.56, p<.001), and mask wearing in crowded places (t=4.96, p<.001). As for the factors influencing the compliance to respiratory infection prevention, major (β=0.31, p<.001), influenza vaccination of the year (β=-0.15, p=.046), and mask wearing in a crowded places (β=-0.31, p<.001) were identified as a significant variable in the multiple regression analysis. In conclusion, since respiratory infections continue to occur even after the termination of COVID-19 epidemic, it is necessary to make efforts to promote compliance to respiratory infection prevention practice, and it is expected that the factors identified in this study can be used as the basic data when developing a respiratory infection prevention program targeting college students.

Background : Reduced lung compliance and increased lung resistance are the primary lung mechanical abnormalities in acute respiratory distress syndrome (ARDS). Although there is little information regarding the mechanisms responsible for the increases in the respiratory resistance of ARDS, bronchodilators have been frequently administered in mechanically ventilated ARDS patients. To determine the effect of a bronchodilator on the respiratory mechanics depending on the level of applied positive end-expiratory pressure (PEEP), the changes in the respiratory mechanics by salbutamol inhalation was measured under the variable PEEP level in patients with ARDS. Materials and Methods : Fifteen mechanically ventilated paralyzed ARDS patients (14 of male, mean age 57 years) were enrolled in this study. The respiratory system compliance, and the maximum and minimum inspiratory resistance were obtained by the end-inspiratory occlusion method during constant flow inflation using the CP-100 pulmonary monitor (Bicore, Irvine, CA, USA). The measurements were performed at randomly applied 8, 10 and 12 cm $H_2O$ PEEP before and 30 mins after administrating salbutamol using a meter-dose-inhaler (100ug${\times}$6). Results : 1) The maximum inspiratory resistance of the lung was higher than the reported normal values due to an increase in the minimal inspiratory resistance & additional resistance. 2) The maximum inspiratory resistance and peak airway pressure were significantly higher at 12cm $H_2O$ of PEEP compared with those at 10cm $H_2O$ of PEEP. 3) Salbutamol induced a significant decrease in the maximum and the minimum inspiratory resistance but no significant change in the additional resistance only was observed at 12cm $H_2O$ of PEEP(from $15.66{\pm}1.99$ to $13.54{\pm}2.41$, from $10.24{\pm}2.98$ to $8.04{\pm}2.34$, and from $5.42{\pm}3.41$ to $5.50{\pm}3.58cm$ $H_2O$/L/sec, respectively). 4)The lung compliance did not change at the applied PEEP and salbutamol inhalation levels. Conclusion : The bronchodilator response would be different depending on the level of applied PEEP despite the increased respiratory resistance in patients with ARDS.

The variable control in the inductive inference for the confirmation and verification when the experimental data are collected is studied by applying the principle of probability inference. The control in engineering experiments is to protect any effect by of intervening variable except primary independent variable on the dependent variable. By the special condition the possibility for developing a phenomenon will be maximized; otherwise, by the extraneous condition the possibility for developing a phenomenon will be minimized. By doing so, the control may provide insurance for the causal relationship between the certain prior event (independent variable) and the post-event (the dependent variable). Some experiments by using both elliptical trainer and tread mill under the variable control are performed in order to find the relations between the energy expenditure, the respiratory exchange ratio (RER), and the heart rate (HR) against the exercise speed.

Purpose : The purpose of this study was to investigate the effects of stabilization exercise and breathing exercise on the flexion relaxation phenomenon (FRP) and respiratory parameters in patients with chronic low back pain. Methods : We randomly allocated 30 chronic low back pain patients (CLBP) to a stabilization exercise (SE) group (n=15) and a breathing exercise (BE) group (n=15). FRP was measured using surface electromyography (SEMG). Thoracic excursion was measured with a cloth tape measurement technique. The SE group participated in a stabilization exercise program and the BE group participated in a breathing exercise program three times a week for 12 weeks. The data was analyzed using paired t-tests for comparisons of flexion relaxation ratio (FRR) and respiratory variables. Independent t-tests were used for comparison of inter-group FRR and respiratory variables. The significance level was set at .05. Results : FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF) values-increased significantly after exercise in both the SE and BE groups (p<.05). The thoracic excursion measurements after exercise increased significantly in both groups (p<.001). VAS values decreased significantly in both groups (p<.001). There were no significant differences between the two groups in FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF)-or VAS values after exercise (p>.05). For thoracic excursion after exercise, the BE group was significantly higher than the SE group (p<.001). Conclusion : We found that FRP and respiratory variables increased significantly after SE and BE for 12 weeks in CLBP. Thoracic excursion-a respiratory variable-suggests that treatment was more effective in the BE group than the SE group.

Idiopathic interstitial pneumonia (IIP) is a histologically identifiable pulmonary disease without a known cause that usually infiltrates the lung interstitium. IIP is largely classified into idiopathic pulmonary fibrosis, idiopathic non-specific interstitial pneumonia, respiratory bronchiolitis-interstitial lung disease (ILD), cryptogenic organizing pneumonia, desquamative interstitial pneumonia, and acute interstitial pneumonia. Each of these diseases has a different prognosis and requires specific treatment, and a multidisciplinary approach that combines chest high-resolution computed tomography (HRCT), histological findings, and clinical findings is necessary for their diagnosis. Diagnosis of IIP is made based on clinical presentation, chest HRCT findings, results of pulmonary function tests, and histological findings. For histological diagnosis, video-assisted thoracoscopic biopsy and transbronchial lung biopsy are used. In order to identify ILD associated with connective tissue disease, autoimmune antibody tests may also be necessary. Many biomarkers associated with disease prognosis have been recently discovered, and future research on their clinical significance is necessary. The diagnosis of ILD is difficult because patterns of ILD are both complicated and variable. Therefore, as with other diseases, accurate history taking and meticulous physical examination are crucial.

Infantile hemangioendothelioma(IHE) of the liver is the most common vascular tumor in infants before the age of 6 months. It is a histologically benign tumor with potentially life-threatening complications. The clinical manifestations are variable, ranging from asymptomatic forms to intractable high-output heart failure. In addition, abdominal mass, intraperitoneal hemorrhage due to rupture of mass, respiratory distress, hematologic abnormalities and jaundice can occur. Diagnostic work-up is through doppler ultrasound sonography, computed tomography scan, magnetic resonance imaging and angiography. Treatment consists of medical treatment, interventional therapy, surgical resection and liver transplantation. We experienced symptomatic IHE in a premature neonate who presented with high output heart failure and respiratory distress. Initial medical treatment and steroid therapy failed to improve his condition. Coil embolization of left hepatic artery resulted in improvement of respiratory symptoms. However, a left lobectomy was performed because the mass size was not decreased with development of collateral vessels. The infant was well, after a successful discharge from the hospital.

This study was conducted to observe the change of limbs stroke and respiration gas parameters in our new bicycle fitness system. We hypothesized that the variable force of left and right limbs might be effective for sensing stimulation in modified new unequal pedal bicycle system. It has been developed, which can provide visual information and different length of pedal with left and right limbs. Experimental results showed different activities between the left and right limbs where the activity of the left limb increased than that of right limb. Especially, the soleous muscle activity increased both in control and experimental groups by this training method. But oxygen and carbon dioxide partial pressures in respiratory gas increased during training method. These results suggest that acidosis of blood was led by this process. Consequently, this bicycle training is concluded that aerobic training could affect different limb activities. Finally, we expect that our new bicycle system will be effective for healthcare with proper balance between the left and right limbs.
