Hydroid specimens were collected from the coasts of Isl. Jeongjokdo (Taean) and Gampo Harbour, Korea, on 10 May and 19 October 2010. Two of the species identified as Sertularia tenera G.O. Sars 1874 and Plumularia halecioides Alder 1859 are new to Korean fauna. They are described with illustrations.

Rotifers inhabiting Oshipcheon (Samcheog-city), one of the natal streams of chum salmon in the east coast, were studied taxonomically. As a result, 19 species/subspecies were identified, and of which five rotifers are newly recorded from Korea: Cephalodella forficula, Dicranophorus forcipatus, Notommata glyphura, Bryceella tenella, and Habrotrocha collaris. Among these Korean new records, Habrotrocha collaris is also new to Asia.

Among alcohol preserved adult specimens of non-biting midges(Chironomidae, Diptera) which were collected at various localities in 1977-1978, three new species are identified and named Pentapedilum parasordens n. sp., Micropsectra koreana n.sp. and Rheotanytarsus gayaensis n. sp., which are fully described with illustration.

Eight species of Chironomidae (Diptera) which are new to Korea are described with illustrations. They are extremely rare species in Korea, as only one or two specimens have been collected since 1977 throughout the country. Microchironomus tener, Stictochironomus akizukii and Paratendipes nubilus belong to subfamily Chironominae, and the other five species: Diplocladius cultriger, Limnophyes minimus, Metriocnemus fulvofasciatus and Parametriocnemus stylatus belong to subfamily Orthocladiinae.

Recent molecular and polyphasic taxonomic approaches toward bacterial systematics have played a significant role in revolutionizing our insight in the taxonomy of bacterial organisms. This advance has also contributed greatly to delineation of new taxa from bacterial organisms isolated from a variety of natural sources of Korea. Recently, many bacterial organisms have isolated from soil, seawater, foods, wastewaters and humans of Korea and have been subjected to polyphasic taxonomic study. From the results of this study, some isolates have been found to be members of new genera and new species.

An asteroid specimen was collected in adjacent water of Gisamun, Gangwon-do in the East Sea, Korea at a depth of 170 m by fishing net at May 2013. It was identified as Nearchaster (Nearchaster) pedicellaris (Fisher, 1910) belonging to family Benthopectinidae of order Notomyotida, which was new to the Korean fauna. The genus, family, and order of this species were also new to Korean waters. The partial sequence of mitochodrial cytochrome c oxidase subunit 1 (CO1) was determined for the first time and registered at GenBank.

A new cyclopoid species belonging to the genus Acanthocyclops is described from several mountain springs in South Korea. This species is allied to A. kieferi species group in sharing 11-segmented antennules, but is, clearly distinguished from them by its single apical spine on the third endopodal segment of leg 4 and an extra spine on the distal segment of leg 5 in both sexes.

Two new records of Scleroderma species from South Korea are described here. Comprehensive taxonomic studies of Scleroderma specimens were conducted at the Korea National Arboretum. Based on morphological and molecular data (fungal barcode sequences), two new records (S. laeve and S. nastii) were confirmed. Herein, morphological descriptions, including Scanning Electron Microscope (SEM) images of basidiospore ornamentation, and a taxonomic key of Korean Scleroderma species are provided.

In an online shopping site or offline store, products purchased by each customer over time form the purchase history of the customer. Also, in most retailers, products have a product taxonomy, which represents a hierarchical classification of products. Considering the product taxonomy, the lower the level of the category to which two products both belong, the more similar the two products. However, there has been little work on similarity measures for sequences considering a hierarchical classification of elements. In this paper, we propose new similarity measures for purchase histories considering not only the purchase order of products but also the hierarchical classification of products. Unlike the existing methods, where the similarity between two elements in sequences is only 0 or 1 depending on whether two elements are the same or not, the proposed method can assign any real number between 0 and 1 considering the hierarchical classification of elements. We apply this idea to extend three existing representative similarity measures for sequences. We also propose an efficient computation method for the proposed similarity measures. Through various experiments, we show that the proposed method can measure the similarity between purchase histories very effectively and efficiently.
