The purpose of this study was to evaluate and compare film thickness of five kinds of resin luting cements [Comspan, Panavia Ex, Maryland bridge adhesive, All-bond C & B cementation kit, and Super-bond C & B]. Zinc-phosphate cement and glass-ionomer cement were used as the control group. In order to measure the film thickness the methods used were in broad compliance with ADA Specification No. 8, a tapered-die system that simulates clinical conditions more closely, and the connected tapered-die system that simulates bridge conditions. The inorganic filler size of resin cements was also examined with scanning electron micrographs. The results were obtained as follows ; 1. The film thickness of resin cements was increased in the order of Comspan, Panavia Ex, Super-bond C & B, Maryland bridge adhesive, and All-bond C & B cementation kit. Maryland bridge adhesive and All-bond C & B cementation kit showed significantly higher film thickness than the control group(p<0.01). 2. For all resin cements, there was a significant difference of film thickness between the ADA method and the tapered-die system. Generally, the tapered-die system demonstrated lower film thickness than the ADA method(p<0.01). 3. There was no significant difference in film thickness between the tapered-die system and the tapered-die bridge system in all resin cements(p<0.01). 4. The scanning electron microscope showed that the cement with larger filler had a tendency to be higher in film thickness.

The purpose of this study was to evaluate the fracture resistance of the four kinds of dental porcelains for the all-ceramic crown(Vita In-Ceram, Vita Hi-Ceram, IPS-Empress, Vitadur-N) and one kind for the metal-ceramic non(Vita VMK 68) was used as the control group. In order to determine the fracture resistance, the hi-axial flexure strength was measured at a crosshead speed of 0.5mm/min, and the Vickers hadrness was measured at an indentation load of 1kg for 20 seconds. The results obtained were summarized as follows ; 1. The maximum Weibull modulus of 24.61 for Vitadur-N and the minimum one of 852 for IPS-Empress were observed ; the maximum characteristic strength of 353.26MPa for Vita In-Ceram and the minimum that of 63.20MPa for Vitadur-N were also observed. 2. The maximum mean bi-axial flexure strength of 339.12MPa for Vita In-Ceram and thd minimum one of 61.99MPa for Vitadur-N were calculated. Results of the Scheffe test indicated that the statistically significant difference(P<0.05) existed between Vita In-Ceram or Vita Hi-Ceram and the others ; also between IPS-Empress and Vitadur-N. 3. The maximum mean hardness of $980.55kg/mm^2$ for Vita VMK 68 appeared. Results of the Scheffe test indicated that statistically significant difference(P<0.05) existed between Vita In-Ceram or Vita Hi-Ceram and the others ; also between IPS-Empress and Vita VMK 68.

The purpose of this study was to evaluate the effect of thermocycling on bond strength between metal and resin cement according to thermocycling, and to observe the bond failure modes with optical microscope(X30). For this purpose, Super-Bond C & B and Panavia 21 resin cement were used. Metal specimens were made of Vera-Bond and the surface of specimens were sandblasted with $50{\mu}m$ aluminum oxide. All experimental groups were stored in $37^{\circ}C$ distilled water for 72 hours, followed by thermocycling between $5^{\circ}C$ and $55^{\circ}C$ with 15 second dwell time. 500, 1000, 2000 cycles of thermocycling were executed and the tensile bond strength was measured by Instron Universal Testing Machine(Model 4201) The obtained results were as follows : 1. Super-Bond C & B and Panavia 21 did not show statistically significant difference accor-ding to thermocycling test(P>0.05). 2. Super-Bond C & B specimens exhibited statistically significant higher tensile bond stre-ngth than Panavia 21 for all experimental groups(P<0.05). 3. Super-Bond C & B exhibited mixed mode failure with partial adhesive and partial cohe-sive failure, and most of Panavia 21 exhibited cohesive failure and some mixed mode failure.

As manifested in various urban policies, the Seoul Metropolitan Government(SMG) has made great efforts to improve the pedestrian environment. The City of Seoul has managed “Car-Free Day” events several times, and has designated pedestrian-only streets in many areas. However, it is not always convenient to walk in Seoul. On the streets, citizens still experience narrow sidewalks, streets cluttered with street furniture, and slanted sidewalk angles which are not safe for the mobility disadvantaged. The SMG still has work remaining to enhance the quality of the walking environment. In pursuing this goal, public officials in the SMG have realized an urgent need to seek guidance from a street design manual. Herein, the existing manuals were reviewed to see if they could be of use in the redesign of Seoul streets. It was found that the manuals were simply not up to the job, presenting many problems. First, in most cases, the national government created the manuals. Thus, they did not reflect the unique characteristics of Seoul’s built environment. Second, the manuals provided only general direction for street design, without specific details to deal with the diverse types of streets found in Seoul. Third, they set the focus on a few elements of street design, while considering various factors in an integrated manner is a key element for desirable street design. For these reasons, the SMG plans to create a Seoul Street Design Manual. As preliminary research for such a manual, this study drew on lessons from other cities in the world. The manuals for various cities abroad all have a common theme: they aim to convert current “Incomplete Streets” that were designed for automobiles to “Complete Streets” that put pedestrians and bicycles on equal footing with cars. Nevertheless, their coverage of design elements, the level of details included in the guidelines, and the contents of the manuals still differ from each other. Throughout the 1980s and 1990s, Seoul experienced rapid growth with the construction of major urban highways such as the Olympic Freeway. It may be evident that Seoul has not treated pedestrians and bicycles with due respect compared to automobiles. Therefore, we suggested that the Seoul Street Design Manual should focus on the design of Complete Streets, for which the design principles are proposed herein. Moreover, for a city like Seoul with various street types, it is important to provide customized design strategies for each street pattern. Readers can also find them in this report. Since physical developments, including buildings and transport infrastructure, have almost been completed, it is crucial to implement the design manual step by step. Although a design scheme such as road diet is a desirable outcome for pedestrians, it would bring about chaos for auto users if executed instantly. Learning from cities abroad(such as the Parklet program in San Francisco), we proposed a method to carry out the design proposal through gradual and acceptable changes. Finally, the creation of a fine street design is a task that should involve a wide variety of fields including transportation, urban design, and environmental engineering. This report also suggested organizing a Task Force(TF) to collect useful ideas from many disciplines. That way, citizens walking on the streets in Seoul could benefit for years to come.
