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.

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.

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.

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.

It was revaluated about taxonomical position of the Tilingia tsusimensis (Yabe) Kitagawa (Apiaceae) collected from Mt. Gaya, Mt. Geumo, and Mt. Songni in Korea. Its diagnostic features include slightly dorsally compressed mericarps, acute-prominent ribs, ternate leaves, and dimorphic white petals. It is morphologically similar to Cymopterus and Pimpinella in having ternate leaves. It is distinguished from Cymopterus having asymmerty mericarps, 3-4 mericarp ribs, and winged dorsal ribs. Pimpinella differs in having slightly laterally compressed mericarps without ribs and conspicuous calyx teeth. Also, it looks like Angelica with obsolete calyx teeth and multilayer pericarps, but is distinguished by having its broadly winged lateral ribs and strongly dorsally compressed mericarps. Tilingia tsusimensis formed a monophyletic clade or sister group relationship with a genus Angelica based on ITS sequences. Based on the above observations, we conclude that this plant is here referred to T. tsusimensis (Yabe) Kitagawa.
