The purpose of this study is to comprehend the change of the terms and the structure of the Pungpanbu in the T-shaped wooden shrines in the later Joseon period through the Salleung-dogamuigwes. Following conclusions have been reached through the study. First, the terms in the Salleung-dogamuigwes were similar to Yeonggeon-dogamuigwes but timing difference was verified. The word about the frame of Pungpanbu was different from the current. Second, in accordance with the extended of Pungpanbu, the members of frame of Pungpanbu had been increased and it had been changed to the lattice. The members of Pungpanbu used as plan dimensions and the size of the members had been gradually increased. Third, the Pungpanbu had been extended to protect the side of T-shaped wooden shrines. At the same time, the range of Chukjungbang had been extended. This was the result of the efforts of the era to reduce the range of plaster. This affected the overall elevation change of T-shaped wooden shrines.

This paper reports the application of radiocarbon wiggle-matching for Korean wooden artifacts such as buildings and Buddhist statues for precise dating. Nine quinquennial (every five-year) samples of 41 years (AD 1250-1290) for AMS radiocarbon measurements were prepared from a wooden board used for the Main Hall at Jeongsusa (temple) in Kangwhado, Korea, which was dendrochronologically dated. The 95.4% confidence interval of radiocarbon dating prior to wiggle matching was 113.3 year in average. When wiggle-matching technique was applied, it became 20 years, 5.7 times smaller than that produced without wiggle matching. The results indicated that wiggle-matching technique using the calibration curve for northern hemisphere (IntCal04) can produce precise dates for Korean wooden artifacts, at least, for the $13^{th}$ century.

Three bronze bells excavated from the Hoeamsa temple site were investigated for their microstructures and chemical compositions in an effort to understand the technology applied in fabrication, which may represent the related industry established in the early Joseon period. The result shows that the bells were cast from alloys of approximately 85% copper-8% tin-7% lead. The chemical analysis for ten trace elements shows that they were all kept below 0.3 weight %, suggesting that the alloys were made of relatively well-refined copper, tin and lead. The presence of sulfur and iron indicates that chalcopyrite or chalcocite may have been used in the smelting of copper. Evidence has been found that the bells were cast by pouring the liquid metal from the top of the sand molds that were set up in an upright position. No additional treatments, thermal or mechanical, other than a little grinding were applied upon the completion of casting. After the shaping process, a balancing plate was attached to the top of the bell using a steel connection ring. The connection assembly was then fixed to the main body by using molten bronze as a solder. The surface inscription was found carved using different techniques. The differences in the order of strokes and the calligraphic style indicate that the carving was carried out by more than one master. In the absence of documentary evidence on past bronze technology, the present bronze bells with known chronology, provenance and the main agent of production, prove to be a rare and valuable archaeological material for the understanding of the related technology in use in the early Joseon period.
