Abstract This research is a comparative study on the geological natural monuments of South and North Koreas. The classification system on natural monuments between South Korea and North Korea is similar, but North Korea's designations are relatively well-balanced. The geology field of South Korea was composed of rocks, caves, fossils and general geology, whereas that of North Korea was subdivided into rocks, fossils, strata, mineral springs, hot springs, geography, waterfalls, lakes, caves and pools. Unlike South Korea, North Korea designates and preserves geological structures such as fold and fault, and representative outcrops of mine. It is suggested that South Korea has to establish natural monument management policies for preserving geological structures and outstanding outcrops of mine. The 47-year period of preserving natural monuments in South Korea was divided into the stages I (1962~1980), II (1981~1995) and III (1996~2008). The designated numbers of geological natural monuments in the stage I, II and III average 1.1, 0.1 and 2.6, respectively. The number of geological natural monuments in South Korea is highest in Jeju province, whereas that in North Korea is highest in Gangwon province. This implies that natural monuments have been well protected especially in the locality of slow urbanization.

In the traditional signature techniques, anyone can verify the signed message. It may cause a problem since a receiver of the signature can transfer the conviction of signature to a third party. In 1996, Jakobsson introduced a designate verifier signature(DVS) which is allowed to verify only specific verifier. DVS is the solution of conflict between authenticity and privacy because it provides message authentication without non-repudiation property. In this paper based on the notion of certificateless, we suggest a certificateless strong designated verifier signature scheme including the notion of strong which provides privacy of the signer. We suggest a scheme which is first trial to propose a certificateless strong designated verifier signature scheme including the notion of strong and non-delegatability, although it is not more efficient than previous one.

This study is a qualitative study for "Seung-mu" of Song, Jae-Sub, who has been designated as Intangible Cultural Heritage No. 15 by Daejeon City, performed by literature research. The significance of this study is to examine the life and to understand the performance of Bup-Woo Song Jae-Sub, the Seung-mu performer, and to supply the knowledge of the dance moves, rhythm, and materials of the Seung-mu. Song Jae-Sub's Seung-mu is characterized by a soft appearance, and the process of assimilation and conformity to nature is melted into the dance moves, and it contains the aesthetics of humility that puts the opinions of others before oneself. Furthermore, Song Jae-Sub's Seung-mu is characterized by his humility and flexibility expressed through dance.

Recently, biometric techniques such as face recognition, finger-print recognition and iris recognition have been widely applied for various applications including door access control, finance security and electric passport. This paper presents the method of using finger-vein pattern for the personal identification. In general, when the finger-vein image is acquired from the camera, various conditions such as the penetrating amount of the infrared light and the camera noise make the segmentation of the vein from the background difficult. This in turn affects the system performance of personal identification. To solve this problem, we propose the novel and fast method for extracting the finger-vein region. The proposed method has two advantages compared to the previous methods. One is that we adopt a locally adaptive thresholding method for the binarization of acquired finger-vein image. Another advantage is that the simple morphological opening and closing are used to remove the segmentation noise to finally obtain the finger-vein region from the skeletonization. Experimental results showed that our proposed method could quickly and exactly extract the finger-vein region without using various kinds of time-consuming filters for preprocessing.
