Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (DPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of CDPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

Despite significant improvement in the mechanical properties of composite resins, They still undergo wear, discoloration, fracture with time. Repair is an alternative to the total replacement of old composite resin restoration, because it reduces pulpal trauma, and cost, time. The successful bond strength between new and old composite usually requires micromechanical retention and coating of old composite with unfilled resin. Micromechanical retention can be achiveved by sandblasting, grinding, or acid etching. Now application of bonding agent after sandblasting is known as the most effective surface treatment for composite repair. The aim of this study is to compare sandblasting with grinding as micromechanical reughening method and to evaluate the effect of bonding agent, silane primer, and post-cure thermocycling on shear bond strength of repaired posterior composite resins. The three posterior composite resins were used in this study. Charisma, Aelitefil, and Z-100 were for substrate resin and only Z-100 for repair resin. Then they were thermocycled(5∼55℃, 1,000 cycles) for aging. The substrate surface was treated by various methods : 1 group-NT (no treatment), 2 group-BA (bonding agent ; Scotchbond MP), 3 group-SB (sandblastion with 50μm alumina partcles), 4 group-GR (400 grit Sic grinding), 5 group-SB+BA, 6 group-GR+BA, 7 group-SB+PR (primer : Scotchprime-ceramic primer) +BA, 8 group-GR+PR+BA. After speciments 24 hours and the other 5 specimens were thermocycled again(5∼55℃, 600 cycles). The sheal bond strength wa measured by Instron testing machine with 1.0 mm/min. cross-head speed. From the experiment, the following results were obtained : 1. Shear bond strength of sandblasted group was significantly higher(P<0.05) than that of control group, but there was no significant difference(P>0.05) of bond strength between ground group and control group. However application of bending agent after grinding significantly(P<0.05) increase the bond strength of contorl group. 2. Although the values of shear bond strength of silane-primed groups were higher than those of unprimed groups, there was no significancy(P>0.05) 3. When bonding agent has been applicated, there was no statistically significan difference between sandblasted group and group group(P>0.05). 4. No statistically significant difference of shear bond strength was made by therocyling(5∼55℃, 600 cycles)

The object of this study was to synthesize the experimental light-activated glass ionomer cement change of glass components such as aluminum, fluorine, calcium, and strontium. To reinforce the glass ionomer cement, additions of metallic powder, ceramic powder, and light-activated composite resin to glass ionomer cements were performed. Radiopacity, comprehensive strength, bond strength, fracture toughness, sloubility, and cytotoxicity of the various experimental glass ionomer cements were investigated. From the experiment, the following results were obtained: 1. Experimental light-activated glass ionomer cement showed similar physical and mechanical properties to commercial glass ionomer cement. Radiopacity, resistance of solubility, fracture thoughness, and compressive strength of the experimental cement were superior to those of commercial cements, but bond strength and biocompatibility of the experimental cement were inferior to commercial cements. 2. Addition of amalgam powder to light-activated glass ionomer cement resulted in the lower compressive strength and fracture toughness, but addition of aluminium powder resulted in the enhanced the fracture toughness. 3. Addition of alumina powder (Al₂O₃) could enhance the compressive strength and fracture toughness of the glass ionomer cement without sacrificing of the esthetic property. 4. Physical mixing light-activated glass ionomer cement with light-activated composite resin could enhanced the physical properties except for bond strength.
