This study analyzed the aspect of action and mean in Japsaeknorum. Secondly, this study contrasted Japsaeknorum with Mime. Thirdly, the characteristics of gestures in Japsaeknorum were analyzed. The results, obtained by those steps are subordination, hostility, cultural control, the comic characteristics by situation, functional role, the sublation of competition and conflict, the variation of subordination and deviation, the end of subordination and deviation. The korean mime is a heritage of Western culture. But in the history of korean mime, it make every effort to seek the korean form of mime. Therefore, this study is very helpful to seek such a way.

현재 일부 전자책은 전통적 책의 인터페이스를 매개하여 사용자 경험을 복제하고 있다. 그러나 새로운 개발환경에서 근대의 시각경험이었던 파노라마, 디오라마와 같은 재현의 수용은 앞으로의 새로운 전자책이 새로운 사용자 경험을 만들어 나갈 것으로 예측하게 한다.

The annual productions of yam and its aerial bulbils are estimated to 5,000 and 2,500 ton, respectively. But the majority of bulbils had been discarded without specific use. In this study, methanol extract and its organic solvent fractions were prepared from bulbils of Dioscorea batatas Decne, and their antimicrobial, antithrombin, and antioxidant activities were evaluated, respectively. The methanol extract contained 58.98% of water-soluble materials as like yam's extract. But the bulbils's extract contained 12-folds of total polyphenol and 3.4-folds of total flavonoids compared than yam's extract, respectively. For antimicrobial activity the hexane and ethyl acetate fraction showed strong antibacterial activity at $500{\mu}g/disc$ concentration against gram-negative and gram-positive bacteria. Antifungal activity was not observed in any fractions. Strong antithrombin activity was found in the hexane fractions. At 4.8 mg/mL concentration thrombin time (TT) was over 300 sec, which is 4-folds extended than the TT of yam. In a while, the ethyl acetate fraction showed strong DPPH scavenging activity ($IC_{50}$ of $38.1{\mu}g/mL$), SOD-like activity and reducing power, which are comparable to vitamin C or BHT. Our results suggest that the bulbils of yam as yam tuber have useful bio-activities, such as antibacterial, antithrombosis, and antioxidant activity.

Shipwreck remains below the seabed not only effect the ocean currents and tides, but influence the physical properties of sediments and sedimentary environments that comprise the seabed. In particular, the influence of local shipwrecks discovered buried in the seabed on the sediment is visible. In this study, sediments were collected from the surrounding area of Taean Mado No.3 shipwreck using grab samplers and vibro-corers. The physical properties of these sediments were analyzed to evaluate the impact of the Taean Mado shipwreck No.3 remains. Sediment core analysis by means of density and ultrasonic velocity showed that shear strength tended to increase with depth, whereas moisture content and porosity tended to decrease with depth. Grain size analysis results are shown in terms of Folk's classification, where the grain size of the core samples in the study area indicate mud or sandy mud, and that of the grab sample indicates a muddy sand. Results of the sedimentation rate analysis indicate a rate of 2.84 cm/year and carbon dating of the 150 cm deep seashell indicates the Neolithic age. These sediments were analyzed for the study of the relationship between the Taean Mado shipwreck No.3 remains and the physical properties of the sediment.

X-ray Chest P-A is very important and basic diagnosis examination for pregnant women. For a pregnancy period pregnant women should be treated very carefully not to be exposed to any radiation which might cause harmful damage to women and babies as well. Lead apron is one of the effective methods to protect pregnant women from the X-ray radiation. However, it is difficult to obtain the accurate position of pregnant women during X-ray Chest P-A since conventional lead apron method forces pregnant women to hold the apron by themselves only to make pregnant women very uncomfortable and hard to maintain accurate position during radiation. As a consequence, it is common to get low quality images of X-ray Chest P-A due to the overlap of apex of lung and scapular. In order to fix this problem, we made new design lead apron that allowed pregnant women to be more comfortable to maintain accurate position during X-ray Chest P-A position. Finally, with this new design lead apron, it was possible to get the best optimized images of X-ray Chest P-A of pregnant women by minimizing overlapping apex of lung and scapular.

The principal objective of this study was to assess the quality characteristics of noodles prepared at ratios of 0% (I), 1.4% (II), 2.8% (III), and 4.2% (IV) Dioscorea japonica powder, based on the wheat flour weight. The lightness of the uncooked and cooked noodles decreased significantly as the amount of Dioscorea japonica powder increased. The yellowness of the cooked noodles were reduced significantly, but the redness of all samples were significantly increased with increasing amounts of Dioscorea japonica powder. The rate of weight increase and volume increase of the noodles, as well as the density, pH, and turbidity of the soups were also assessed. The cohesiveness and gumminess of samples III and IV were significantly lower than those values in samples I and II. The results of our sensory evaluation test evidenced no significant differences in appearance and flavor among all samples. The colors of I and II were better than those of III and IV. The taste and texture scores of IV were the highest, and as a result the overall acceptability of III was most preferred.

This study was carried out to compare isozyme band pattern, growth characteristics and tuber yield of Dioscorea batatas to get basic information for varietal classification. It could be identify clearly by protein and esterase band pattern of leaf, petiole and stem tissue in three cultivar but with peroxidase band it was difficult to identify because of similar pattern in leaf and petiole tissue. Three cultivars has different leaf shape as Dan-ma and Jang-ma were lanceolate, Sukunea was long-heart shape in upper part of plants. In phyllotaxis, Dan-ma and Jang-ma shows alternate and opposite but Suwon 2 shows opposite in upper parts of stem. Root length shows significant difference from 9.7cm to 51cm respectively as 30cm, 51cm and 9.7cm in Dan-ma, Jang-ma and Sukunea. Tuber yield of three cultivars were 27.5M/T in Dan-ma, 22.8M/T in Jang-ma and 22.8M/T/ha in Sukunea.

Radar Cross Section (RCS) is a factor directly related to survivability, and a design to reduce the presence of this factor is needed. The upper structure, guns, radar and so on are related to warship RCS, but radar RCS reduction is difficult because of complex shapes involved. In this paper, an enclosed mast, which is one modern method for reducing radar RCS, and the characteristics of an applied Frequency Selected Surface (FSS) are analyzed. The RCS reduction ability of an enclosed mast has been confirmed by comparing RCS analysis results for a general radar with that of an enclosed mast for available frequency according to FSS shape. The characteristics of the enclosed mast have also been studied by analyzing the elevation angle and slope of the mast. General radar RCS was high because of its complex shape, but low RCS was shown for the enclosed mast model, which had a simpler shape.

Since there were only few countries that could find wild ginseng grown in nature, the culture of digging wild ginseng was only developed in a small number of countries. In a time when the orthodox head-Simmemani has disappeared, the tangible and intangible culture of Simmemani (wild ginseng digger) is disappearing more and more with the passage of time. So far, the conducted research on wild ginseng diggers was very partial and simplistic as follows: ① Research on the argot of Simmemani, ② Research on the customs of Simmemani, ③ Research on the change of customs of Simmemani, ④ Additional records through interview with Simmemani. Accordingly, no comprehensive study on the Simmemani culture has been done yet. This study supplements the historical materials that were not reflected in previous studies, and discuss on diverse subjects including the definition and classification of wild ginseng, the distribution of wild ginseng and Simmemani, interpretation of wild ginseng digging from a legal and social point of view, the organization responsible for the digging, determination of the date of entering the mountain, preparations, taboos, departure and entry into a mountain, religious events, psalmbook, dream interpretation, search and discovery of wild ginseng, digging, profit sharing, the amount of harvested wild ginseng, and the price of wild ginseng. In addition, Korean wild ginseng digging culture was comprehensively studied by attaching the photos and illustrations of historical documents with the psalmbook of the head-Simmemani.
