In old Korea from the 4th century of 6th cen-tury the lapels of You and upper garment folded slightly. It had tight sleeves and its length was not long reaching to the hips. but from the 7th century the sleeve of You became wider and its length became longer, Chinese You folded very deeply across the breast and its sleeve was tight. The length of Chinese You was short too strectching out to the hips. From the 5th century the sleeve of the Chinese You became wider Chinese trousers with wide crotch appeared in the 4th century during the time when Ezst Jin Dyn-asty ruled China. The upper garments with the wide sleeve was common by the 7th century in China. What is specially noteworthy is that Short-dalnyung appeared in the 5th ∼6th century. In old Korea strings were used to tie the bottoms of the trousers. Trousers with tight crotch did not need the strins. korean trousers with wide lines were narrower than the Chinese trousers at the bottom and it was not necessary to use the strings for people to put them on In China there were both of wide trousers and tight trousers. People tied trousers around the kness with the strings in the formal places but they did not tied the trousers with the strings when they wore the ordinary clothes. Chinese trousers were very wide just like a skirt and they were much wider than wide Korean trousers.

Multi-nozzle spray painting procedure of the inorganic zinc shop primer was established in order to obtain uniform film thickness. The shop primer paint prevents the corrosion of steel block during shipbuilding. When the dry film thickness of shop primer is insufficient, rust will be generated on the steel block. Otherwise, thick coating of shop primer may be a problem of weld defect. So, it is important to obtain the uniform film thickness of shop primer. The uniformity of dry film thickness is affected by spray speed, distance from spray gun to target surface and overlapping span of spray path. In order to uniformly maintain coating thickness of shop primer, the coating procedure was established based on the correlation of shop primer spray variables.

The Korean have admired and lived with decorums through Jeol, a representative practical formality which expresses the decorums intensively. Jeol is the way of greeting native to Korea and an intangible culture close to Korean life style. To be remained as a culture, the traditional propriety Jeol should reconcile to the present life feflecting our history. On this viewpoint, the purpose of this research is to furnish the authority of the creative inheritance on the settlement of Jeol and other decorums suitable to the present. This research is consisted of 1) the study of the meaning of Jeol and 2) the hidtorical research through records. 'Jurye' is regarded as the oldest literature on the systematic explanation about Jeol and has been very often used down the ages. Jindong in 'Jurye' and Kodu in 'Karyejipram' are the same Jeol which expresses the grief in funeral rites. In 'Seonghosaseol', Abae which stands one knee is explained and investigated as the case of offense by the literature. And it is also interpreated as a Jeol with respect, while many other Jeol is to fall an both of kness, Abae is not performed generally. 'Yeki' has brief explanation about Kongsu Manner (to hold hands), Jeol between the king and minister, host and guest, Buinbae, Jeol in custom, wedding ceremony and funeral ceremony and Jeol in drinking manner. In 'Chunchukongyangjeon'. there is the explanation about Jeol of the minister who comes back after his duty to the king. 'Sunjajiphae' interprets Bae and Kyesang and informs that Kuesu is the most respectful Jeol only to the king, 'Seojeon' proves the Jeol habitually used in all kinds of ceremonies and etiquettes. 'Jeongbomunheonbigo' introduces the custom of Jeol in Shilla, Koguryo, Buyeo, Koryo eras by using literature and shows the commoness of both kneeling down generally. The result of this research has the meaning for the creation of life culture in the basis of the spirit 'Onkojisin'(reviewing the old and learning the new) by establishing the present Jeol with tradition.

Although corn is regarded as the most feasible forage corp, its relatively low content of protein is the critical we a kness for animal feeding. Many researches have been carried out to improve protein level in corn forage, however, there are no indicatable results but corn-legume intercropping. Plot test and proximate analysis were fullfill to compare dry matter yield and available nutrients of silage corn mono-culture system with those of corn-legume intercropping system of forage plant and silage. The MO culture system were observed by two stage of maturity, milk stage (Aug. 3), yellow stage (Aug. 24), and obtained following results. 1. Dry matter yields per 10 a at milk stage in corn mono-culture system was 596.2kg and corn-legume intercropping systems were 609.0 kg (corn-cowpea), 591.0 kg (corn-soybean) and 563.1 kg (corn-frenchbean), respectively. And comparable to them, 1508.9 kg (corn mono.), 1482.8 kg (corn-cowpea), 1482.6 kg (cornsoybean), 1379.1 kg (corn-frenchbean) were harvested at yellow stage. 2. The general trends of chemical composition by stages of maturity in corn mono-culture systems were higher than that of corn-legume intercropping system. 3. Crude protein content in corn-legume silages were significantly higher than corn mono-culture at yellow stage, except corn-frenchbean intercropping system. 4. Crude fiber content in corn-legume silage was higher than corn mono-culture silage harvested at yellow stage. 5. Consequently, corn-legume intercropping improved nutritional quality of silage than that of corn-monocultivated silage.
