Objectives: The AHERA method by the US EPA, ASTM E2356-04, and HSG264 by the UK HSE, all of which are hazard/risk assessment methods for asbestos-containing building materials, were reviewed and compared based on 231 homogeneous areas. In addition, the current Act on Asbestos Safety Management (enforcement: April 29, 2012) was reviewed and analyzed. This trial provided fundamental data for improving the current asbestos hazard/risk assessment method. Methods: For the hazard/risk assessment of 77 asbestos-containing public buildings including schools, 231 homogeneous areas were selected, each of which was assessed using AHERA, ASTM E2356-04, and HSG264. Results: The matching rate of the hazard/risk assessment stood at 20.4 percent between AHERA and ASTM, at 71.4 percent between AHERA and HSG264 and at 17.8 percent between ASTM and HSG264. The AHERA method includes a seven-category rating scale. There were three categories, two of which have three subcategories. ASTM provides two decision-making charts consisting of ten rating scales for current condition estimation and for potential for disturbance estimation. In addition, the HSG264 method has a total of 20 scores with four items, and then provides four grades. This HSG264 method cannot clearly separate current condition and potential for disturbance. Conclusions: In the Korean Act on Asbestos Safety Management, the hazard/risk assessment method for asbestos-containing building materials should consider balance between current condition estimation and the potential for disturbance estimation.

<P>Exposure to particulate emissions from printer and cigarette smoke affects the structure and function of mitochondria, which may account for the pathogenesis of respiratory diseases. The addition of charge for the pollutant aerosols may increase the toxicity by their deposition in the lower respiratory tract. The mitochondrial damage in the lung of asthmatic mice was assessed by examining the levels of reactive oxygen species (ROS), lipid peroxides, reduced glutathione, and the activities of isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, succinate dehydrogenase, malate dehydrogenase, complexes I to IV, and cytochrome c. The oxidative phosphorylation (levels of adenosine triphosphatase) was evaluated for the assessment of mitochondrial functional capacity. We found highly significant elevated levels of ROS, lipid peroxides, and decreased levels of mitochondrial enzymes in the mice exposed to environmental tobacco smoke and printer emissions + environmental tobacco smoke (ETS). However, mice exposed to printer emissions alone exhibited slight significant variations in the parameters studied. From the results, we conclude that printer emissions exert a synergistic effect in the presence of ETS and induce intense damage to the lung mitochondria by disrupting the structural and functional integrity of the mitochondrial membrane.</P>

The purpose of this study is verifying effect of music therapy when it is applied to stroke patient along with general physical therapy. For this, 25 subjects of study were divided into two groups; experimental group with 13 subjects and control group with 12 subjects. Experimental group was treated with general physical therapy along with music therapy for 6 months, and control group was treated only with physical therapy for 6 months. After 6 months, walking speed and functional intensity of muscle movement of the lower part of the subjects' body were measured. The result of this experiment was analyzed by SPSS WIN 13.0 and it shows as follows. In an aspect of SCGS (Self-selective Comfortable Gait Speed), the average of experimental group showed decrease of 4.23 m/sec, from 24.31m/sec to 20.08 m/sec. In MGS (Maximal Gait Speed), the average of experimental group showed decrease of 4.92 m/sec, from 20.23 m/sec to 15.31 m/sec (p < 0.01). The functional intensity, of muscle movement of lower part of subjects' body of control group, measured before and after the experiment, increased by 279.2 m in average comparing with that of experimental group's 905.4 m in average. This increase had statistical meaning (p < 0.01). These results above show that rather than treating only with physical therapy, treating physical therapy along with music therapy is much more efficient in improving walking function and functional intensity of muscle movement of lower part of the body of stroke patient.
