나주 복암리 정촌 고분 1호 석실에서 화살통 장식 6점이 출토되었다. 유기물로 만들어진 화살통은 매장 상태에서 부식되어 없어지고 금속으로 만들어진 화살통 장식물만 남게 된다. 정촌 고분 화살통 장식은 형태적으로 2점씩 쌍을 이루며, 출토 위치에 따라 화살통 2점을 장식한 것으로 추정된다. 화살통 장식은 화살의 방입부(方立部)를 꾸며주는 대륜상금구와 방입부와 허리띠를 연결하는 배판(背板)을 장식하는 판상금구로 나누어진다. 1호 석실 목관2에서 출토된 화살통 장식은 대륜상금구만 확인되었으며 1호 석실 동남쪽에서 확인된 화살통 장식은 허리띠에 사용된 추정 대구, 판상금구, 대륜상금구가 확인되었다. 화살통 장식의 분석 결과, 철제 판에 금동 판을 접합한 철지금동장식제(鐵地金銅裝飾製)이며 표면을 정(釘)으로 점을 찍어 선과 문양을 만든 것을 알 수 있다. 성분 분석 결과(XRF), 금동 표면은 24~40wt% Au, 50~93wt% Cu가 검출되어 금도금 표면에 청동 부식물이 형성되었음을 확인하였다. 금도금 층의 SEM-EDS 분석 결과 광택을 내기 위한 작업선이 확인되었다. 또한 7~9wt% Hg가 검출되고 도금 층에 아말감 덩어리가 확인되어 아말감 도금한 것을 알 수 있었다. CT와 FT-IR 분석 결과 대륜상금구는 철제 판 아래 견직물이 2중으로 겹쳐 있으며 그 아래 옻칠편도 붙어 있었다. 이는 대륜상금구를 방입부에 부착할 때 직물을 덧대어 밀착력과 장식성을 높였으며, 옻칠 된 방입부 표면이 함께 떨어진 것으로 추정된다. 반면, 판상금구는 철제 판 아래 유기물이 두껍게 붙어 있다. 재질을 확정하기 어려우나 배판의 잔재로 보인다. 이러한 나주 정촌 고분 출토 화살통 장식의 특징은 4세기 후반~5세기 후반의 백제, 신라, 가야 문화권과 유사한 형식을 보여주며 당시 수준 높은 고대 금속 공예 제작 기술을 확인할 수 있었다.

Objectives : Before Liver, Heart, Spleen, Lung, Kidney was widely accepted as Five Viscera, there had been several former types of Viscera system in pre-Western Han era. Above them, the Five Viscera system consisted of Liver, Heart, Stomach, Lung, Kidney was not yet hardly studied. So we tried to prove it's existence and tried to find it's historical context. Material and Methods : Via preceding research analysis, 6 books were selected as research material, and some other pre-Eastern Han dynasty classics were also analyzed. Results : We found direct evidence of above Five Viscera system in Zhuixingxun (墜形訓) in Huainanzi (淮南子), Wusemaizhen (五色脈診), and Western Han dynasty lacquer figure with meridian-points (excavated in Laoguanshan, Chengdu, China). Other clues showing existence of above Five Viscera system was also found in Yinyangshiyimaijiujing (陰陽十一脈灸經), Pianquecanggongliechuan (扁鵲倉公列傳). The rising of above Five Viscera system was related to physiological viewpoint transition of viscera in Western Han dynasty. Conclusions : In Western Han dynasty there was another Viscera System consisted of Liver, Heart, Stomach, Lung, Kidney.

Most of buildings have been deteriorated with time-elapse by reflection of the building location, material, environmental circumstances and so on. The performance would go down and be demolished if anything could not be done after constructed. The maintenance should be required to preserve a decent living condition or improve a inferior condition by various plans and practices. The maintenance plan needs various data such as a repair scope, a repair time, a forecasted cost, a plan of management and so forth. Among the above required data for planning the maintenance, the deterioration characteristics of the building components would be first analyzed. The deterioration pattern would be a key role to affect and make a maintenance plan. In this paper, it aimed at classifying the deterioration patterns of building components. A deterioration pattern would be analyzed between the cumulative repair cost and time-elapse and modeled with these relations. A deterioration patterns are classified into 4 types-a accelerated type, a straight type, a temporary type and a slowly type. As a result of this research, a accelerated type includes window, window frame, general paintings, general water proofing in building components. A straight type includes the lacquer paintings, furnishings in building components and water supply pipe, boiler, sanitaries in mechanical facilities and lighting in electric facilities. Based on these research results, further study should be conducted to include any other components and an estimating model.

Tripitaka Koreana were made during Coryo Dynasty from 1236 to 1251 A.D. Buddhist scriptures were engraved on 81.340 wooden plates. Some plates were varnished with Rhus lacquer, but most of them were uncoated. Macroscopically, most of the plates appeared intact due to the storage in a well-ventilated wooden house. Because, they were irregularly used for printings with ink, it can be assumed that they were repeatedly exposed to ink-water and drying processes. The present were made to examine the changes of wood cell structures occurred during long-term aging deterioration processes in these dry archaeological wooden plates. Light, scanning and transmission electron microscopes were employed for this study. Wedge-shaped cracks and delamilations were found from the lumen side toward the compound middle lamellae and they progressed toward primary or secondary walls. A large amount of hypae in vessels and the degradation of vessel-ray pit walls by the fungal hyphae were observed. When compared to the recent wood, the birefringence of wood fibers was considerably lower or completly disappeared, suggesting the degradation of crystalline cellulose in these wood samples. The degradation of the cell wall could be also revealed the calculation of crystallinity with X-ray diffraction and the size of crystalline region was estimated.
