  • A nondestructive experimental feasibility study was conducted using magnetometer to find buried cultural objects at pottery and steel matters in low-relief mountaineous area of Doojeong-dong, Cheonan, Chungnam Province from May 23 to July 18, 1998. Magnetic survey was carried out with $20cm{\times}20cm$ grid in a site of $20m{\times}40m$ before excavation, and the distribution of magnetic anomalies was compared with the results of excavation. Magnetic sensor was located on the surface of ground during the magnetic survey on the basis of an experimental result. Positive magnetic anomalies of maximum 130 nT are found over a pair of potteries. Magnetic anomaly map reveals several anomalous points in the 1st and 4th quadrants of the survey site, from where potteries and their fragments were confirmed. Six points out of seven points cprrelated with magnetic anomaly are found contain earthwares, whereas a magnetically uncorrelated location produced earthware made of unbaked clay. Steel waste such as cans and wires hidden in soil and bushes also influenced magnetic anomalies. Therefore, it is better to remove such steel wastes prior to magnetic survey if possible. Some magnetically anomalous points produced no archaeological object on excavation. This may be explained by shallower level of excavation than burial depth.

  • Objectives : In case of herbs decoction, the ceramic or earthware pots was recommended, but not the metals, particularly iron or aluminum, which could cause unknown chemical reactions. In Korean Medical classics, it has been known that some herbs including Caulis Lonicerae Japonicae (CL) were not recommended to boil with iron pot. This study investigates the physical changes of extracts of CL with or without iron. Methods : CL was decocted with reflux cooling extraction system to prevent evaporation and volatilization. Content of polyphenol was detected by Folin-Denis method and the levels of loganin and chlorogenic acid were evaluated by UPLC. Results : The color of extract with glass beads (GB) is yellowish brown, and the iron beads (IB) is blackish brown. Polyphenol and chlorogenic acid levels were reduced in IB extracts. Conclusions : The color of extract was change to blackish brown, and polyphenol and chlorogenic acid levels were reduced in CL extract with iron. Therefore, iron pots is not suitable for CL extraction.

  • The purpose of this study is to examine the realities of the chaotic use of terms, 'tattoo' and 'moonsin', through the empirical field researches. This paper will research the differences in the origins and the etymological meanings of 'tattoo' and 'moonsin' through examining related literatures. Clarifying the term definitions on 'tatto' and 'moonsin', this research is to help fashion consumers to use these terms discretely. In order to figure out consumers' perceptive attitude, this study has performed the questionnaire inquiry and has reached the result by analyzing the level of frequency of using the two terms. 1. The result of the term-preference inquiry tells that consumers prefer 'tattoo' to 'moosin'. However, the inquiry shows considerable number of them use the two terms indiscretely. 2. The study on the perceptions from the two terms shows: the term 'tattoo' is often related to positive images-fashionable, charming, and sexy, and the term 'moonsin' to negative ones-violent, anti-social, and demonic. 3. Both 'tattoo' and 'moonsin' shares the similarity in terms of engraving patterns on skin and coloring them. 4. 'Tattoo' is originally derived from the Polynesian word 'tatau', which means 'artistic'. 'Tatau' is a kind of ethnic art practiced on Polynesian people's skin. The design patterns and practicing techniques are very similar to those on the Polynesian earthware called 'Lapita'.
