The pulpous of this study is to investigated the kind and feature of the knots used in four categories, "living, clothing, ceremony, and decoration", after analysing and examining 42 knot remains of the folklore museum of On yang. The method were by old books and various kind's related books, history of knots and kind of knots investigated and analyze relics were actual proof investigation of real things and supplementary materials were photos, drawings, and museum's explanation used. The results are as is following ; First, a knot is twisted by two threads, formed in the process of twisting, become in equal shape, and made in symmetry. Second, In knot's names, there are sangkang, karakge, ankyongchip, jamjary, kukhwa, bol, byongary, memi, kkondiki, kong, yonbong which are easily seen in nature. Third, a knot was used in as living things in the era of the three Kingdoms, as a decoration such as Buddhism goods in Koryo. In the era of Cho sun, Because of the development of knot's kind and the variety of service, it was the target of restriction as a luxury. Fourth, as a result of investigating museum's relics, a knot was smaller than the chief object because that is a decoration. Fifth, there are 8 kinds for living and clothing which are simple knots "doramaetup, karakgemaetup, and sangtchokmaetup". Sixth, the complex knots such as kukhwamaetup, byongarymaetup, and 3bolkamkae emaetup are used on pangchang, chokja, nambawi, and chobawi. Seventh, there are 10 kinds for ceremony, the simple knots are twisted and the complex knots such as kukhwamaetp, maehwamaetup, nabimaetup, and sasaekgupoki are used. Eighth, there are 14 kinds for decoration, the simple knots such as doraemaetup, kakagemaetup, santchokmaetup, and ankyongchipmaetup and the applied knots such as kukhwamaetup, byongarymaemaetup, changkumaetup, nabimaetup, and seokssima etup are used. There are 42 knot remains in the folklore museum of On yang. Of them, there are 33 kinds in the present, 17 used. that is because only several knots have been used. Finally, to forget the knot's way, we will set up a plan to keep with it.

The demilitarized zone (DMZ) is a border barrier with 248 kilometers in length and about 4 kilometers in width crossing east to west to divide the Korean Peninsula about in half. The boundary at 2 kilometers to the south is called the southern limit line. The DMZ has formed a unique ecosystem through a natural ecological succession after the Armistice Agreement and has high conservation value. However, the use of facilities for the military operation and the unchecked weeding often damage the areas in the vicinities of the southern limit line's iron-railing. This study aimed to prepare basic data for the restoration of damaged barren vegetation. As a result of classifying vegetation communities based on indicator species, 10 communities were identified as follows: Duchesnea indica Community, Hosta longipes Community, Sedum kamtschaticum-Sedum sarmentosum Community, Potentilla anemonefolia Community, Potentilla fragarioides var. major Community, Prunella vulgaris var. lilacina Community, Dendranthema zawadskii var. latilobum-Carex lanceolata Community, Dendranthema zawadskii Community, Plantago asiatica-Trifolium repens Community, and Ixeris stolonifera-Kummerowia striata Community. Highly adaptable species can characterize vegetation in barren areas to environment disturbances because artificial disturbances such as soil erosion, soil compaction, topography change, and forest fires caused by military activities frequently occur in the barren areas within the southern limit line. Most of the dominant species in the communities are composed of plants that are commonly found in the roads, roadsides, bare soil, damaged areas, and grasslands throughout South Korea. Currently, the vegetation in barren areas in the vicinities of the DMZ is in the early ecological succession form that develops from bare soil to herbaceous vegetation. Since dominant species distributed in barren land can grow naturally without special maintenance and management, the data can be useful for future restoration material development or species selection.
