  • Precast concrete finishing panels can be implemented in different colors, textures and designs relatively freely by different designers in different finishing materials. Therefore, we tried to develop a PC finishing panel that can be applied in the field by using various color pigment and concrete surface retardation method and polishing method.

  • The modern unique woodworking furniture has been made in earnest from 50 years ago. Some oil from nut such as soybean, walnut and perilla, which is usually used in our common life, has been used as finishing material for the unique woodworking furniture. Recently, woodworking studio business among the whole furniture industry has grown gradually and many woodworkers uses various kinds of imported wood finishing oil. Many woodworkers use the imported finishing oil in the old ways instead of understanding the characters of the various kind of oil and It causes some serious problems in furniture finishing process. Therefore, this study aims at taking theoretical approach in wood finishing oil and presenting correct usage in understanding the types and characters of oil. Resultingly the new method of oil finishing for wood is suggested and this suggestion is to guide woodworkers into the right usage of wood finishing oil.

  • Utomatic finishing process requires the development of high efficient and precision abrasive machining method for die and molds. This study describes the evaluation of the finishing characteristics, such as sufrace roughness, topography and material removal depth, of the electrolytic chemical mixed abrasive machining method. Experimental setup is composed of 3 axis machining center, a newly developed finishing attachment with constant pressure, electrode and electrolytic bath. Finally, we achieved a successful result that surface roughness is 0.01 .mu. m Ra and material removal depth is 145 .mu. m after 100 times repeat-finishing using electrolytic (0.8A,30V) mixed abrasive (#400 CBN, #320 Sic) machining method.

  • Automatic finishing process requires the development of high efficient and precision abrasive machining method for dies and molds. This study describes the evaluation of the finishing characteristics, such as surfrace roughness, topography and material removal depth of the electrolytic mixed abrasive machining methods. Experimental setup is composed of 3 axis machining center, a newly developed finishing attachment with constant pressure, electrode and electrolytic bath. Finally, we achieved a successful result that surface roughness is $0.01\mu$m Ra and material removal depth is $120\mu$m using electrolytic(0.8A. 30V) mixed abrasive (#400 CBN, #320 SiC) machining method.

  • The objective of this study is to apply water repellent and flame retardant finishes simultaneously to the fabric used for automobile. Both two step and one step methods were tried to apply the finishing agent to the fabric. In the two step method, water repellent agent was treated first, and flame retardant agent was applied next. The reverse finishing process was also attempted. In the one step method, flame retardant agent and water repellent agent treated to the fabric in one bath. The results of two step method revealed that the finishing effect was better when the water repellent agent was treated first than when flame retardant agent was treated first. In one step method, fluoro water repellent agent was superior to silicon water repellent agent.

  • Finishing is the final process in molds manufacturing and consumes much process time. Also, it influences on surface quality of molds. But, there are few systematic methods to control the process. In this work, basic experiments were carried out to study the machining characteristics of the finishing tools. From the experiments, critical surface roughness and wear coefficient are suggested to reduce the number of finishing steps and to plan a systematic finishing procedure. Comparison experiments were carried out between the expert's method and the new method, which is based on the results of this research. From the experiments, it is verified that the systematic method takes less time and generates less form error in the machined surface than the worker's method.

  • Finishing materials are very important to restrain fire spread from a compartment to another in a fire situation. Therefore, the evaluation of combustible properties for the combustible material is essential to apply finishing materials into a generic buillding or s special occupancy structure. In this study, the testing methods for evaluation of combustible performance of finishing materials of domestic were surveyed in order to prepare the guideline of application of finishing materials in nulear power plant.

  • Traditional External Insulation Finishing System(EIFS) is applied to apartment construction by performing structural framework and insulation finishing work sequentially. Separate execution of the three works increases construction cost and duration. Concurrent construction method of EIFS, which performs framework and insulation finishing work simultaneously, is introduced in order to solve these problems. However, the introduced method is exposed to the risk of construction delay caused by bottlenecks due to interacting processes and resources. Therefore, this paper presents a simulation model suitable for estimating work productivity of the concurrent construction by considering predecessor and successor processes to optimize resource allocation and minimize construction delay.

  • Andongpo, 100% Korean hemp fabric was treated with the glyoxale resin type finishing agent and/or the soluble urethane type finishing agent to determine the optimum process condition of the crease resistant finish and the crease recovery of treated sample fabrics was evaluated for the study. The treatment conditions for the study were 6 conditions, such as, A-1~A-6, in which A-1 was the condition of treatment glyoxale resin type finishing agent only and A-2~A-6 were the condition of treatment both glyoxale resin type finishing agent and soluble urethane type finishing agent. Among the 6 conditions, the crease recovery of the sample treated with A-4 condition was $148^{\circ}$(angle of recovery method) and grade 3.2(appearance method) and so, these samples showed the excellent crease recovery. From the result, 15g/l of the catalyst conc., 50g/l of the glyoxale resin type finishing agent cone., and 40g/l of the softner were the optimum treatment condition for the crease resistant finish of the andongpo.
