May-June precipitation (253 years : A.D. 1746∼1998) of Yungdong region (coastal area of East-central Korea) was reconstructed using two tree-ring chronologies of Pinus densiflora sampled from Daeseung Fall area in Sorak Mountains. Dry periods were 1765∼1800 (longest dry period), 1835∼1845, 1890∼1910, 1920∼1940 and 1980∼1995, and wet ones 1810∼1830, 1850∼1890 and 1950∼1970. In long-term variation, late 18th century was dry. The 19th century May-June (250㎜) was wetter than the 20th century (231㎜) and the former indicated higher variability than the latter. Major wet/dry periodicities in May-June precipitation series reconstructed were 3 years in short term and 60∼80 years in long term. The present reconstructed data agreed to the ancient rain gauge 'Chukwooki' data (1777∼1907) of Seoul (central-west Korea) in low frequency variations except early 1800s.

The purpose of this study is to verify the change of body posture by putting on the late $19^{th}$ century English women's bodice or waistcoat. This study analyzed the female somatotype which puts on upper garments of Victorian era with using 3D body scan technology. Two sets of $19^{th}$ century women's bodice and waistcoat patterns were developed with the $19^{th}$ century model size and those patterns were used for making the experimental garments. The fit of experimental garments was evaluated by the degree of change with posture and waist measurements. Three women with the same waist girth measurements with the model size were participated to the fitting test. The postural change was measured from cross-sectional body diagrams. The result of this study showed that the waist measurement of the late $19^{th}$ century English women's bodice and waistcoat pattern was smaller than the waist girth measurement. These garments compressed the midriff of the body and it made women's distinct body silhouette. The waist girth measurement of 1876 bodice pattern was 9.2cm smaller than presented model size. The subjects' waist girth measurements were shortened by 5.0~6.1cm after wearing the 1876 bodice garment. The waist girth measurement of 1880 waistcoat pattern was 7.1cm smaller than presented model size. The subjects' waist girth measurements were shortened by 2.7~3.7cm after wearing the 1880 waistcoat garment. The back side parts of their waist were compressed and their postures were changed. The neck and shoulders were moved forward after wearing the experimental garments. These results showed that body posture could be changed to "S" shape silhouette as wearing the late $19^{th}$ century English women's bodice or waistcoat.

Glass pieces excavated from Mireuksa Temple dated $7^{th}$ century A.D. were characterized by chemical composition, specific gravity and melting point. Lead isotope ratios of lead glasses were also compared with those of lead ore to attribute which lead ore was delivered for making lead glass. It was known that some lead glasses found in Japan were similar with those of Mireuksa Temple as comparing the data of chemical composition and lead isotope ratios. Characteristics of lead glass from Mireuksa Temple Thirty five glass pieces of Mireuksa Temple were analyzed for five oxides and found that all was lead glass system(PbO-$SiO_2$) with the range of 70~79% for PbO and 20~28% for $SiO_2$. The concentrations of oxides such as $Al_2O_3$, $Fe_2O_3$ and CuO were below 0.4%, 0.3% and 0.9%, respectively. Principal component analysis(PCA) as a statistical method was carried out to classify glasses with the similarities of chemical concentrations. The result of PCA has shown that three groups of glasses were created according to the excavation positions and two major oxides(PbO and $SiO_2$) greatly contributed to the dispersion of glasses on principal component 1(PC1) axis and trace element oxides($Al_2O_3$ and $Fe_2O_3$) for PC2 axis. Most of lead glasses were greenish by the efficacy of iron and copper oxides and some showed yellowish-green. The gravity of lead glasses was about 4.4~5.4 and estimated melting point was near $670^{\circ}C$. Lead isotope ratios of glasses were analyzed and found quite close to a lead ore from the Bupyeong mine in Gyeonggi-do. Comparison with lead glasses found in Japan Lead glasses of Mireuksa Temple were compared with those of Japan on the basis of chemical and physical data. Chemical compositions of Japanese lead glasses dated $7^{th}{\sim}8^{th}$ century A.D. were nearly similar with those of Mireuksa Temple but lead isotope ratios of those were separated into two groups. Three distribution maps of lead ores of Korea, Japan and China with lead isotope ratios were applied for lead glasses found in Japan. The result have shown that the locations of lead glasses from Fukuoka Prefecture coincided with the region of northen part of Korea and similar with those of Mireuksa Temple and lead glasses from Nara Prefecture dated $8^{th}$ century A.D. were located in the region of Japanese lead ore. This research has demonstrated that lead glasses of Mireuksa Temple conveyed to Miyajidake site, Fukuoka Prefecture around $7^{th}$ century A.D. and glass melting pots and glass beads excavated from Nara Prefecture confirmed the first use of Japanese lead ore for production of lead glasses from the end of $7^{th}$ century A.D.

May rainfall (317 years: A.D. 1682~A.D. 1998) of western region of Sorak Mt. was reconstructed using a tree-ring chronology of Pinus densiflora 5. et 2. The reconstruction indicated that the 1690~1710년, 1745~1755 and 1847~1853 periods were the least May rainfalls, whereas 1715~1733 and 1835~1845 the greatest ones. The wet period of 1835~1845 was agreed with that found in Songni Mt., central Korea. This wet epoch seems to be widely spreaded in Korea. There were found no significant differences among the means of the 18th, 19th and 20th century's May rainfalls. The major periodicity of May rainfalls was 2~4 years.

A large underground wooden structure of Shilla period which was presumably built in the 5th century A.D. was excavated at Gomo Sanseong Fortress, Mungyeong, Gyeongsangbuk-do. Of 12 wood member samples obtained on the site, 8 hardwoods under family Fagaceae and 4 softwoods under family Pinaceae were separated through light microscopy. Among hardwoods, 5 were found to be Cerris section, 2 Prinus section, and 1 Castanea crenata. On the other hand, 4 softwoods were all identified as Finns densiflora.

Archaeomagnetic dating method is used to assign a date to the archaeological remains in which burnt soil is found by measuring the changes in terrestrial magnetism with the thermal remanent magnetization retained in burnt soil. This method, in particular, is quite useful to determine an age of the archaeological remains in which no properties are found, which makes it difficult to assigning a date. Hemp kiln and lime kiln fall under remains of these features, and 21 and 5 archaeomagnetic data from both kilns respectively were obtained by measuring the- remanent magnetization in burnt soil samples that are extracted in hemp kilns and lime kilns in the country. The results of archaeomagnetic dating with these data show the age range of the hemp kilns is between the late 10th century A.D. and the middle of the 19th century, and that of the lime kilns is between the early 16th century A.D. and the middle of the 18th century. The factor that the number of data collected from the hemp kilns was comparatively more than those from the lime kilns might affect the result, however corresponding to the fact that hemp had been used for a long period of time, the period of hemp kiln are widely spread over the chronological table. And the archaeomagnetic dating of lime kiln, in view of archaeological periods, is not only in accord with the late Joseon period when the tombs with lime-soil mixture barrier in trend; this is also telling that its width of archaeological period is comparatively narrow.

This study is to review the costumes of female Shamans through Gamrotaenghwa(甘露幀畵) in the late Joseon Dynasty of the 18th and 19th centuries. The picture of Mudangnaeryeok(巫堂來歷) showing Shamanic performances which is kept in Kyujanggak, Seoul National University was the only one thing enabling to compare with the Shamanic costumes shown in Gamrotaenghwa. The earlier Gamrotaenghwa doesn't show the Shamanic features but that of the later part of 18th century shows specific costumes so that the scene of Shamanic performance can be guessed. The Shamanic costumes are classified into 5 types. Type A is considered to have followed the figures shown commonly in earlier Gamrotaenghwa of the 16th and 17th centuries, rather than the traditional costumes. Types B through E show the costumes of the Joseon dynasty. With the basic costumes of skirt and Chogori(a kind of jacket, Type B), the variable costumes worn for each type of Shamanic performances are Mongduri(蒙頭里, Type C), Jeonbok(戰服, Type D) and Cheolrik(天翼, Type E). Reviewing the general style of those costumes, the upper part was tight and the lower part was silhouette of big volume, and the length of Chogori was a little long in the early of 18th century but it became shorter with narrower sleeves from the later part of the same century. According to the general literatures about the outer collars were not overlapped and its side parts were open, with half or no sleeves. In case that the target of Shamanic performance is male god, the Shaman wore the male costumes represented by Cheolrik and Jeonbok. Because these Cheolrik and Jeonbok which were worn during the Shamanic performance have the symbolic meaning to correspond with the male god, they didn't function as ordinary costumes.

In the U.S.A. from the late 19th to the early 20th century, the big business system emerged surpassing the British Empire economy. Such growth resulted from the realization of the "American-productive mode' being derived from the continuous immigrants inflow, renovative development of transportation, national markets formation and R&D of the science·technology. During 10 years after 1895, American economy was prevalent with the combination trends by the vertical or horizontal integration and these both mixed systems. As such big business was recognized, the American domestic citizens expressed the strong doubt to the revolutionary change and its public benefits and inaugurated the anti-big business campaign with deep concern that the American traditional symbol 'land of the wealth and opportunity' would be threatened. Although the governmental organizations controlling big business were established and the control laws were enforced, the American society accepted the new economic order. This situation resulted from the American economic prosperity, material affluence and managerialism of the big business.

People in the Ancient Society of Korea liked golden earrings. The Royal Family or the nobility wanted to make more splendorous golden earrings in order to display their high-ranking positions. However, appearances or production methods of golden earrings differ a little by countries, for example, Goguryeo, Silla, Baekje, Gaya, etc. Therefore, by closely examining articles discovered from tombs, we can know which country they were from. In particular, earrings of Goguryeo and Silla are similar to each other while those of Baekje and Gaya are similar. This would be closely related with political relationships between the two countries. The shape of golden earrings in the middle of the $5^{th}$ century A.D. is relatively simple. However, since the latter half of the $5^{th}$ century, golden earrings in the Ancient Society of Korea changed in the direction of long length or significantly splendorous surface decoration. Accordingly, we can estimate the period of production by analyzing golden earrings discovered from a tomb. In addition, the above trend was common all the earrings in the Ancient Society of Korea, which implies that each nation closely exchanged reciprocally at that time.

We have used the Naju Oryang-dong Kiln, the Jar coffin producing center from the 5th to early 6th century A.D. found for the first time in Korea in 2002 and conducted trace element analysis of Jar coffin objects excavated in Jar coffin the old tomb area formed mainly around Yeongsan valley, the consuming area of the same period as our main research objects. For this analysis, we have used both the NAA method, the non-parametric micro-minerals analysis. In order to compare and verify these remains, we have used the results from the analysis on the Jar coffin remains in the Mandong remains, Jeonbuk district. We have quantitatively analyzed 17 types of elements from the Jar coffin remains sample to allow for various and correct analysis. With their results, we could find out that the jar coffins made in Oryang-dong kiln teo are statistically identical to those in Daean-ri Old tomb/Shinchon-ri 9th old tomb, Okya-ri old tomb, and Banam-Old tomb. Also, we can conclude that there is a high possibility that ongwans produced from Oryang-dong kiln being used in Daean-ri Old tomb/Shinchon-ri 9th old tomb, Okya-ri old tomb, and Banam-Old tomb was distributed through some form of trade. On the other hand, we could obtain other analysis results that jar coffins excavated and investigated in the Mandong remains and Ithe npyong Old tomb were likely from other Jar coffin kilns through trade and distribution.
