The custom and shroud for funeral rites of the early 17th Century based on the excavated costume from the grave of Mrs. Jung (1565 - 1614) are studied in this paper. The grave was located in the Pohang, Kyungbuk Province and was excavated in, April 1999. The remains consist of one set of epitaphs, 33 pieces of costume, 7 pieces of cloths, and 14 pieces of funeral accessaries. From these remains, this study newly reveals : 1) a specific funeral custom for the upper class from the fact that her husband, Ja-Hun Ki, was in the position of Prime Minister for the Chosun government when she died, 2) a fact that women also wore a formal dress with round-shaped collar (Dalryoung) and a concubine could use rectangular tablets ((Hyungbae) with peacock pattern according to her husband's rank, 3) a whole set of shroud used for women in the early 17th Century, and 4) specific construction methods for individual shroud.

The Yan mountain area of the northern part of Hebei province and its local neighbor area is categorized main-distribution area of the northern bronze culture of the Eastern Zhou period(770bc~221bc). Recently, it was discovered the concrete character of the culture by a large scale excavation of the Yuhuangmiao cemetery at Jundu mountain. In the chinese scholarship, the cultural character of this area has established the independent cultural type that is distinguished from the Bronze culture of existing. In this paper, I have as a target of analysis remains relate to the Yuhuangmiao culture of the mountain area of northern Hebei in the Eastern Zhou period. And I would like to judge about diverse infuluential relationships of the character of the Yuhuangmiao curture and the Bronze culture, especially burials, burial customs and the characters of the excavated article. In particular, diverse infuluential relationships of the upper Xiajiadian culture Ordos bronze culture and The Central Plains cultural from The Yan state have a important meaning to understand about the character of the Yuhuangmiao culture and the beginning development process. Ultimately, it is peculiar characters of the Yuhuangmiao culture that a shaft gave with stone compartment protecting a coffin as a symbolic form, mask-burial customs such as mainly burials of the living with the dead dogs, a drum shaped jar, a tripod jar with two handles, a short bronze sword with circle hilt, Central Plains cultural bronze containers, bronze halberd and horse-shaped accessories of cartage horse trapping are distinguished from a local neighbor, the bronze culture from northern. The territory of time-space of The Yuhuangmiao culture can be dominately recognized bewteen the upper Xiajiadian culture and Ordos bronze culture. It is the Yan culture after the middle Warring States Period considering with the peculiar chacters which reflected by burials and bural customs and diverse infuluential relationships with peripheral cultures.

In order to investigate the corrosion pit occurrence and growth characteristic of M.E.F.(martensite encapsulated islands of ferrite) dual phase steel was made with a suitable heat treatment of raw material(SS41), a corrosion fatigue test was performed under rotary bending in the salt solution having a concentration from 0.01 wt percent to 3.5 wt percent. The fatigue strength of dual phase steel was remarkably decreased with an increase in concentration of salt solution; approximately from 63% to 80% in case of dual phase steel and from 40% to 71% in case of raw material. Corrosion pit occurred in the martensite phase and fatigue cracks from corrosion pits were selectively propagated in martensite phases. In the observation of corrosion pits at the origin of fatigue cracks, it had been found that corrosion pits were grown into hemispherical pits and a/c(the surface diameter, 2c and the depth, a of corrosion pit)was about 1.0-1.5regardless of the variation of salt solution concentration. The difference of corrosion pit depth growth rate was increased with an increase in concentration of salt solution according to an increase in stress level.

This study examined the total phenolic and flavonoid compounds, and the antioxi dant activity of major cultivars of Prunus mume in Korea. The total phenolic content ranged from 64.13 to $93.43mg{\cdot}100g^{-1}$, with the content in 'Osuku' being higher than that in the other cultivars; a difference in the content among cultivars was observed. The total flavonoid content was $6.16{\sim}18.57mg{\cdot}100g^{-1}$, showing a significant difference, with the highest content being noted in 'Gojirou'. The DPPH radical scavenging activity was measured and was relatively high for Nanko, Kamakami, Natsuka, Dana, and Osuku cultivars. When ABTS radical scavenging activity was measured, all the cultivars showed a scavenging activity over 80%, with the scavenging activity of 'Osuku' being the highest. With respect to nitrite scavenging ability, all cultivars exhibited a high scavenging activity of over 50%, with the highest activity observed for 'Nanko' (76.03%), 'Gojirou' (70.56%), and 'Yourou' (70.32%). Based on the study results, it is considered that Prunus mume can be a useful resource because of various substances with functional physiological activities.

Comparisons are made between the first hyperpolarizability $\beta$ of pure N-(4-nitrophenyl)-(L)-prolinol (NPP) and poly (methyl metacrylate) (PMMA) or poly-p-(phenylene terephthalates) (PPT) with NPP side group determined with two different methods, electric-field-induced second-harmonic generation (EFISHG) and hyper-Rayleigh scattering (HRS) methods. Both techniques yield the same values within the experimental errors for pure NPP and NPP-PMMA in 1,1,2,2-tetrachloroethane solution. But the measured results of NPP-PPT polymer in 1,1,2,2-tetrachloroethane solution are showing that the first hyperpolarizability was enhanced with an enhencement of a factor 9.7 in EFISHG and a factor 2.4 in HRS relative to pure NPP. These results indicate that nonlinear optical chromophores organized as side groups of polymers with a rigid backbone contribute coherently to the secondorder nonlinear response of the polymer in the dc electric field as polar polymer chains. hains.

In the case of a capsule that can acquire and transmit images from the intestines, the size of the module and the battery capacity in the capsule are subject to restriction. The capsule must be swallowable and the battery must maintain the stable power during the capsule travels in the gastrointestinal tract. Therefore, it is important to control the endoscope using bi-directional wireless communication. In this study, encoder and decoder CPLD modules for bi-directional capsule endoscopes were designed and implemented. The designed controller for capsule endoscope can transmit the images of GI-track from inside to outside of the body and the capsules can be controlled by external controller simultaneously. The designed and implemented controller was verified by an in-vivo animal experiments. From these experiments, it was verified that the CPLD module for bi-directional capsule endoscope satisfied the design specifications.

Hoseonmu belongs to the genre of a composite of song, music, and dance. At that time, there was no widely known record of Hoseonmu in Baekje, but it is clear that it was popular enough to be invited to Changan by Emperor Yang of Sui. The musical instruments, songs, and dances were analyzed through the research method of literature and the content of the Hoseonmu version was established. The setting of the stage for the performance of Baekje instrumental music reveals its characteristics through sabangak from Gigaku in the neighboring countries. The stage for Hoseonmu was set up utilizing the creation of the imperial performance stage in the Baekje instrumental music. In particular, Hoseonmu has two types: heavenly and earthly. The heavenly Hoseonmu can be found on the wall of the Cave No. 220 formed in the Chodang (618-707) era. They include Dongbang Pharmacopoeia jingbian and Western Paradise jingbian. Hoseonmu would have chosen to be the fast-paced spinning dance. Motions for Hoseonmu could be set up through them. Meanwhile, Mimaji's instrumental dance is presented. Six dancers appear in two turns of the performance. Four dancers in front row and other two in the back are dressed up as hunters, wearing goblin masks, and holding flowering plum tree branches in their right hands. Through this, the movements and costumes of Hoseonmu are reproduced in more detail. Various sectors of education, theater, dance, and tourism in the Hoseonmu contents of Baekje instrumental music contributed to the Korean Wave.
