Science, technology and innovation (STI) is crucially important to eradicating poverty, and making advances in various areas such as agriculture, health, environment, transport, industry, and telecommunications. Therefore, it is vital to the overall socioeconomic development of nations. The indispensable role of STI in the competitive globalized economy led to several attempts to measure national STI capacities. The present study outlines STI capacity around three sets of capabilities: technological capabilities, social capabilities, and common capabilities. The Global Science, Technology and Innovation Capacity (GSTIC) index was developed to provide current evidence on the national STI capacities of the countries, and to improve the composite indicators used for such purposes. The GSTIC ranks a large number of countries (167) on the basis of their STI capacities and categories them into four groups: i.e. leaders, dynamic adopters, slow adopters, and laggards. For more meaningful assessment of the STI capacities of nations, it captures the achievement gaps of individual countries with the highest achiever. The study also provides ranking and achievement gaps of nations in the nine GSTIC pillars: technology creation, R&D capacity, R&D performance, technology absorption, diffusion of old technologies, diffusion of recent innovations, exposure to foreign technology, human capital, and enabling factors. A more detailed analysis of the strengths and weaknesses in different pillars of STI capacity of ten selected countries is also provided. The results show that there are significant disparities among nations in STI capacity and its various aspects, and developing countries have much to catch-up with the developed nations. However, different countries may adopt different strategies according to their strengths and weaknesses. Useful insight into the strengths and weaknesses of the national STI capacities of different countries are provided in the study.

This study aimed to compare 2 protocols recommended to patients with chronic cervical cord injury: each protocol included breathing exercises (inhalation-oriented or exhalation-oriented) and facilitation maneuver for the accessory respiratory muscles. Seventeen patients with chronic cervical cord injury volunteered to participate in this study, and we randomized these patients into 2 groups: the inhalation-oriented breathing exercise group (IOBEG) and exhalation-oriented breathing exercise group (EOBEG), consisting of 8 and 9 patients, respectively. Patients in the IOBEG performed inspiratory exercises using intermittent positive pressure breathing devices, while those in the EOBEG performed expiratory exercises using incentive spirometry. All exercises were performed by the subjects twice a day for 4 weeks, with each session lasting an average of 20 min. The outcomes were assessed on the basis of the pre- and post-treatment values of vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC. In the IOBEG, no significant differences were observed between the pre- and post-treatment values of any of the measured variables (p>.05); however, in the EOBEG, significant improvement was noted in the VC, FVC, FEV1 measured (p<.05) after the treatment. In addition, the rates of change in the values of VC, FVC, and FEV1 differed significantly between the 2 groups (p<.05). These findings suggest that the EOBEs can enhance respiratory function and are clinically feasible in patients with chronic cervical cord injury. Further studies will be undertaken to evaluate the clinical application of these findings.

Purpose: Fractional exhaled nitric oxide (FeNO) and forced expiratory flow between 25% and 75% of vital capacity ($FEF_{25-75}$) are not included in routine monitoring of asthma control. We observed changes in FeNO level and $FEF_{25-75}$ after FeNO-based treatment with inhaled corticosteroid (ICS) in children with controlled asthma (CA). Methods: We recruited 148 children with asthma (age, 8 to 16 years) who had maintained asthma control and normal forced expiratory volume in the first second ($FEV_1$) without control medication for ${\geq}3$ months. Patients with FeNO levels >25 ppb were allocated to the ICS-treated (FeNO-based management) or untreated group (guideline-based management). Changes in spirometric values and FeNO levels from baseline were evaluated after 6 weeks. Results: Ninety-three patients had FeNO levels >25 ppb. These patients had lower $FEF_{25-75}$ % predicted values than those with FeNO levels ${\leq}25$ ppb (P<0.01). After 6 weeks, the geometric mean (GM) FeNO level in the ICS-treated group was 45% lower than the baseline value, and the mean percent increase in $FEF_{25-75}$ was 18.7% which was greater than that in other spirometric values. There was a negative correlation between percent changes in $FEF_{25-75}$ and FeNO (r=-0.368, P=0.001). In contrast, the GM FeNO and spirometric values were not significantly different from the baseline values in the untreated group. Conclusion: The anti-inflammatory treatment simultaneously improved the FeNO levels and $FEF_{25-75}$ in CA patients when their FeNO levels were >25 ppb.

Background: Although organizing pneumonia (OP) responds well to corticosteroid therapy, relapse is common during dose reduction or follow-up. Predictors of relapse in OP patients remain to be established. The aim of the present study was to identify factors related to relapse in OP patients. Methods: This study was retrospectively performed in a tertiary referral center. Of 66 OP patients who were improved with or without treatment, 20 (30%) experienced relapse. The clinical and radiologic parameters in the relapse patient group (n=20) were compared to that in the non-relapse group (n=46). Results: Multivariate analysis demonstrated that percent predicted forced vital capacity (FVC), $PaO_2/FiO_2$, and serum protein level were significant predictors of relapse in OP patients (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.70-0.97; p=0.018; OR, 1.02; 95% CI, 1.00-1.04; p=0.042; and OR, 0.06; 95% CI, 0.01-0.87; p=0.039, respectively). Conclusion: This study shows that FVC, $PaO_2/FiO_2$ and serum protein level at presentation can significantly predict relapse in OP patients.

Background: Individuals with forward head posture (FHP) have neck pain. To correct the FHP, a posture correction band is commonly used. However, we do not know the posture correction band influenced the pulmonary function in individuals with FHP. Objects: This study aimed to elucidate the effects of the posture correction band on the pulmonary function in young adults with neck pain and FHP and to monitor how the pulmonary function changed over time. Methods: Twenty subjects with chronic neck pain and forward head posture were recruited. Subjects performed pulmonary function test four times: before, immediately, and 2 hours after wearing the postural band, and immediately after undressing the postural band. Vital capacity (VC), forced vital capacity (FVC), peak expiratory flow (PEF), and forced expiratory volume at one second (FEV1) were measured. The modified Borg dyspnea scale was used to measure each subject's responses to the posture correction band. The mixed-effect linear regression was used to the effect of the posture correction band over time. Results: There were no significant differences in VC, FVC, PEF, FEV1 values over time (p > 0.05), although all values slightly decreased after applying posture correction band. However, the score of the modified Borg scale significantly changed after wearing the postural bands (p < 0.05), indicating the subject felt discomfort with posture correction band during breathing. Conclusion: Because the posture correction band did not change the pulmonary function over time, but it induces psychological discomforts during breathing in people with FHP. Therefore, this posture correction band can be used for FHP realignment after discussion with the subjects.

Purpose: The aim of this study was to evaluate functional gait and pulmonary function of patients with subacute or chronic stroke for aperiod after the onset of stroke. Healthy people of similar ages served as a control group. The study focused on the clinical importance of intervention with cardiopulmonary rehabilitation treatment in patients with stroke. Methods: The standard time period used to differentiate the subacute and the chronic stroke groups was six months. Each group, including the control, was allocated 11 subjects. Vital capacity (VC), forced vital capacity (FVC), and forced expiratory volume at one second ($FEV_1$) were measured with a spirometer for each subject. Walk tests (10 m and 6 min) and functional gait tests were then conducted. Results: Significant differences were noted for VC, FVC, and $FEV_1$ between the subacute stroke group and the normal group and between the chronic stroke group and the normal group (p<0.05), but no significant difference was evident between the subacute stroke group and the chronic stroke group (p>0.05). No significant difference was seen between the subacute stroke group and the chronic stroke group in the 6min walk test (p>0.05), whereas a significant difference was observed between the subacute stroke group and the chronic stroke group in the 10 m walk test (p<0.05). Conclusion: The general rehabilitation treatment is effective with respect to functional aspects, but it has limited effect in improving pulmonary function and muscular endurance. Therefore, additional intervention of cardiopulmonary rehabilitation is necessary in the rehabilitation treatment process of patients with stroke.
