  • For effective on-line ARMA parameter estimation, a covariance type ARMA fast transversal filter (FTF) algorithm is presented. The proposed algorithm is a covariance type implementation of ELS(Extended Least Squares) estimator and it is a fast time update recursion which is based on the fact that the correlation matrix of ARMA model satisfies the shift invariance property in each sub-block. The geometric approach is used in the derivation of the proposed algorithm. It takes small computational burden of 13N+37 MADPR(Multiplication And Division Per Recursion). Also, AR and MA orders can be independetly and arbitrarily specified.

  • The most typical morphological characteristics of seeds of eight species in Umbelliferae are summarized as follows: 1. The common characteristics of seeds in Umbelliferae were bi-partite fruits, compound of 2-seeds, (fruitlet) oil canals and funiculus or carpaphore. 2. Seed shape of Umbelliferae were oblong or elliptic and ovate; seed colors were yellow, pale yellow or brown, dark brown or black. 3. Seed size ranged from 2 to 7mm in length and 2∼5mm in width. Angelica dahurica bore the largest seed while Ligusticum acutilobum showed the smallest. The 1000-seed weight ranged from 1. 7g in Bupleurum falcatum to 3.9g in Angelica gigas.

  • This research was carried out for revealing the co-relationships between insect-pollinators and the plant species of Labiatae and Umbelliferae, insects visiting in flower and the flowers in Korea, were studied from April 2010 to August 2012. The sum of flower visiting degrees in Labiatae are shown 21 in Hymenoptera, 16 in Lepidoptera, and the lowest 1 in Diptera and Coleoptera, respectively. The sum of flower visiting degrees in Umbelliferae are shown 27 in Diptera, 24 in Hymenoptera, 21 in Coleoptera, and 13 in Lepidoptera, respectively. 17 pollinator species visited the flower of Angelica gigas, next 15 pollinator species did the flower of Agastache rugosa, 13 pollinator species did the flower of Prunella vulgaris var. lilacina. 13 pollinator species foraged on the flower of Peucedanum terebinthaceum. and then 11 pollinator species on the flower of Angelica dahurica. Only 1 pollinator species visited the flower of Clinopodium chinense var. grandiflora and Isodon excisus. Pollinators of Coleoptera and Diptera visit more frequently to the flowers of Umbelliferae than those of Labiatae. Pollinators of Lepidoptera and Diptera visit more frequently white flower than purple one. This study found out that mutualistic relations between plants and insect pollinators in Korea.

  • This work attempted to study the properties of expression of ground, the composition of outlook and the implications of the connotative symbolic scenery throughout investigating the properties of expression content and method of the scenery, outlook, viewpoint, natural features for each drawing and intention of making 4 old maps, which had been made in the period of the Great Korean Empire and had been called 'Wansan-dohyoung(完山圖形),' 'Jogyeongdan- bigak-jaesil-dohyoung(肇慶壇碑閣齋室圖形),' 'Jeonju-geonjisan-dohyoung(全州乾止山圖形)' and 'Jogyeongmyo-gyounggijeon-dohyoung(肇慶廟慶基殿圖形),' and analyzing the correlation between their drawings. For this aim, observatory investigation by using a map, on-spot investigation, analysis involving the satellite images and internet were carried out with literature review simultaneously. The result of investigation could be sum up as follows. Gyounggijeon(1410), Jogyeongmyo(1771) and Jogyeongdan(1899), where are the core space to lay the historically firm foundation for securing the fact Jeonju is the home of the Royal Family of Joseon, had been built, fixed and extended for giving legitimacy to the Joseon Dynasty and a part of strengthening of royal authority. And these had played an important role of spiritual mainstay from early in the Joseon Dynasty to the era of the Great Korean Empire and had been managed and maintained continuously. It is grasped that the 4 maps consist of Sanhyuoungdo(山形圖; a kind of a mountain map), which is the map for showing a burial place of Lee Han(李翰), the founder of the Joseon Dynasty, and its auxiliary drawings and these had been drawn intensively to justify dignity and authority of the Imperial Family and the Emperor after the name of country was renamed the Great Korean Empire as a part of national undertaking. In detail, Wansan-doghyoung is the key map for announcing the existence of Jogyeong-myo, Gyounggijeon and Jogyeongdan in Jeonju and informing their locations and Geonjisan-dohyoung is the map of divination based on topography for highlighting the geomantic justification of the founder's mausoleum. Jogyeongdan-bigak-jaesil-dohyooung is the partial map detailing for Geonjisan-dohyoung. Jeonju-geonjisan-dohyoung and Jogyeongmyo-gyounggijeon-dohyoung had employed the binary reduced scale and the bird-eye view method and in the above maps, Geonji Mountain is the main mountain and these maps make an exaggeration of the main geographical features, centering Wangjabong and Euimyoso, unlike the real geographical features. Also, the other main geographical features, which are found in the burial place, are expressed in detail by changing the view. In the point of view of 1 set being consisted of 4 maps, 'Wansan-dohyoung' has the property not only as Gunhyoundo, which Gun and Hyoun mean a unit of the administrative district, respectively and Gynhyoundo is a kind of the map for recording their locations, but also as the map of showing their locations. On the other side, 'Jogyoungmyogyounggijeondohyoung' is a kind of lay-out drawing as a partially detailed map. In addition, it has been found out that 'Jeonju-geonjisan-dohyoung' and 'Jogyeongdan-bigak-jaesil-dohyoung' is not only Pungsu- hyounggukdo having the function of Sanhyoungdo but also a detail drawing. On the base of these properties, it is considered that the functionality as a serial map had been strengthened, unlike the existing old maps.

  • Two naturalized species, Chaerophyllum tainturieri Hook. (Umbelliferae) and Barbarea verna (Mill.) Asch. (Cruciferae) were newly reported from South Korea. C. tainturieri., 'Jeon-Ho-A-Jae-Bi', was found at World Cup park in Sangam-dong, Mapo-gu, in Seoul, and the genus Chaerophyllum is reported for the first time from South Korea in the present paper. It is distinguished from the genus Sphallerocarpus by having cylindrical fruit, and each furrow with one vitta. B. verna, 'Bom-Na-Do-Naeng-I', was found on a riverside area of Suyeong River, Geumsa-dong, in Busan. It can be distinguished from B. orthoceras by silique 4-8 mm long , seeds 1-2 mm long, and basal rosette leaves with a 4-11 large pairs of lateral lobes.
