This study aimed to investigate the effects of a comprehensive corrective exercise program on the kyphosis angle and balance in kyphotic adolescents. A total of 62 male adolescents (between the ages of 10 and 18, mean BMI 21.7 kg/m2) with a thoracic kyphosis (TK) angle of ≥ 50° were divided into three groups using the simple randomization method: CCEP (comprehensive corrective exercise program), TEP (thoracic exercise program) and control group. The CCEP program consisted of corrective exercises plus postural perception training (PPT). Exercise programs were applied for 40–50 min, 3 days a week for 12 weeks. The kyphosis angle was measured using a flexible ruler, and balance was assessed using the Romberg index obtained from pedobarography. After training, a highly significant reduction in the kyphosis angle was observed in the CCEP and TEP groups (p < 0.001). Comparison among the groups showed a greater reduction in the kyphosis angle in the CCEP group (p < 0.020). Postural perception improved in the CCEP group versus other groups (p < 0.001). Improvement of the Romberg index (balance) was found only in the CCEP group upon within-group comparison (p < 0.001), with no difference among the groups (p > 0.05). The use of postural perception in combination with corrective exercise programs for thoracic kyphosis represents a comprehensive approach, and PPT can increase the effectiveness of the intervention.

The production of primary aluminum is an energy-intensive industry which produces large amounts of direct and indirect greenhouse gas emissions, especially from electricity consumption. Carbon Emissions Constrained Energy Planning proved to be an efficient tool for reducing energy-related greenhouse gas emissions. This study focuses on energy planning constrained by CO2 emissions and determines the required amount of CO2 emissions from electricity sources in order to meet specified CO2 emission benchmark. The study is demonstrated on and applied to specific aluminum products, aluminum slugs and aluminum evaporator panels. Three different approaches of energy planning are considered: (i) an insight-based, graphical targeting approach, (ii) an algebraic targeting approach of cascade analysis, and (iii) an optimization-based approach, using a transportation model. The results of the three approaches show that approximately 2.15 MWh of fossil energy source should be replaced with a zero-carbon or 2.22 MWh with a low-carbon energy source to satisfy the benchmark of CO2 emissions to produce 1 t of aluminum slug; however, this substitution results in higher costs. This study is the first of its kind demonstrated on and applied to specific aluminum products, and represents a step forward in the development of more sustainable practices in this field.
