  • This paper proposes a new enhancing document clustering method using a synonym of cluster topic and the similarity. The proposed method can well represent the inherent structure of document cluster set by means of selecting terms of cluster topic based on the semantic features by NMF. It can solve the problem of "bags of words" by using of expanding the terms of cluster topics which uses the synonyms of WordNet. Also, it can improve the quality of document clustering which uses the cosine similarity between the expanded cluster topic terms and document set to well cluster document with respect to the appropriation cluster. The experimental results demonstrate that the proposed method achieves better performance than other document clustering methods.

  • The taxonomic revision of the family Mugilidae from Korea was made based on the fish specimens collected from the coasts of the Korea from July 1990 to July 1994. The family Mugilidae was classified into three species belonging to two genera: Mugil cephalus, Liza haematocheilus and Liza carinatus. Previousely Mugil japonicus reported as a species from Korea was confirmed into junior synonym of Mugil cephalus. based on the external and internal morphological characters. A new key to the genera and species of family Mugilidae was proposed and described their distribution in Korea.

  • A taxonomic study of small mammals (Erinaceomorpha, Soricomorpha and Rodentia) was conducted in order to find out the scientific names which have been used in Korea. The synonymy of each species and taxonomical research was reviewed and confirmed in this study. The species names are rearranged based on recent studies. Among the various confused names, available names were adopted such as follows: C. shantungensis shantungensis known as Crocidura suaveolens; C. shantungensis quelpartis known as C. dsinezumi; Rattus tanezumi known as R. rattus, called black rat, roof rat and ship rat, respectively. Apodemus sylvaticus (Muridae, wood mouse) is excluded in the checklist based on indistinct previous records and ambiguous habitation on the Korean Peninsula, and neighbors. In addition, we provide a new Korean vernacular name for Myocastor coypus, called the "Nutria" in Korea. We reflect that several species are repositioned to other genera. A checklist of Korean small mammals and synonym list for each species is provided to avoid confusion of scientific names in Korea. In this study, the list of small mammals in Korea is arranged to 33 species, 20 genera, 8 families, and 3 orders.

Taxonomic reexamination of new species described by Léveillé in the serial papers of Decades plantarum novarum. II. New species currently treated as taxonomic synonyms of other species (Léveillé가 Decades plantarum novarum의 연속 논문에 기재한 한국산 신분류군에 대한 분류학적 검토 II. 신종으로 발표된 분류군 중 분류학적 이명으로 간주되고 있는 분류군)

  • To confirm the taxonomic identity of taxa described by $L{\acute{e}}veill{\acute{e}}$, H. H. A, a French plant taxonomist, in the serial papers of Decades plantarum novarum based on the collections of Fathers Faurie and Taquet from the Korean peninsula, we examined the numerous references that contained taxonomic opinions about $L{\acute{e}}veill{\acute{e}}^{\prime}s$ taxa. Among them, 146 taxa were confirmed as conspecific with other existing taxa. Of them, 79 taxa, including Ajuga devestita, were listed as a synonym of only one species. Sixty-seven taxa, including Bidens robertianifolia, were listed as synonyms of two or more species according to taxonomists. Eight taxa, including Aconitum coreanum, were considered illegitimate names because of later homonym, or other problems. Five taxa, including Rhododendron hallaisanense, were treated either as distinct or conspecific taxa depending on taxonomists.

  • Through taxonomic survey of specimens collected from the coasts of Korea from 1993 to 2006, Dimorphostylis echinata $Gam{\hat{o}}$, 1962 is new to Korean cumacean fauna. Especially, the adult male and female of D. echinata are described for the first time. Dimorphostylis sculpturensis Vassilenko and Tzareva, 1990 is proposed as a synonym of D. acroplicata Harada, 1960 in this research. Also, its female is redescribed for the first time in Korea.

  • Web data mining aims at discovering useful knowledge from various Web resources. There is a growing trend among companies, organizations, and individuals alike of gathering information through Web data mining to utilize that information in their best interest. In science, cloud computing is a synonym for distributed computing over a network; cloud computing relies on the sharing of resources to achieve coherence and economies of scale, similar to a utility over a network, and means the ability to run a program or application on many connected computers at the same time. In this paper, we propose a new system framework based on the Hadoop platform to realize the collection of useful information of Web resources. The system framework is based on the Map/Reduce programming model of cloud computing. We propose a new data mining algorithm to be used in this system framework. Finally, we prove the feasibility of this approach by simulation experiment.

  • Previous surveys on Ulleung-do (Dagelet Isl.) found just ten earthworm taxa while the current survey unearthed a dozen species. Placement of parthenogenetic 'tube' Amynthas dageletensis Hong & Kim, 2005 is resolved as it clearly belongs in synonymy of Metaphire soulensis (Kobayashi, 1938) which becomes a new Ulleung-do record. Other new megascolecids are recorded since Amynthas heteropodus (Goto & Hatai, 1898) and A. baemsagolensis Hong & James, 2001 are confirmed as synonyms of A. corticis (Kinberg, 1867) and A. carnosus (Goto & Hatai, 1899), respectively. The latter taxon is differentiated and its synonym A. pingi (Stephenson, 1925) provisionally revived. New lumbricids are Bimastos parvus (Eisen, 1874), Eisenia japonica (Michaelsen, 1892) and questionably Dendrodrilus rubidus (Savigny, 1826). All confirmed species are common exotics with no endemics. Drawida moniligastrids were not yet located on this remote island for reasons unknown.

  • The bamboo katydid, Palaeoagraecia lutea (Matsumura et Shiraki, 1908) is newly reported in South Korea. Previously, the species was only known in Japan, but currently its occurrence is confirmed in the far southern locality of Hampyeong, Jeollanam-do province of Korean Peninsula. This katydid was collected using a light trap and sound tracing in the bamboo forest. It is regarded as a rare stenotopic species. The features of male Palaeoagraecia lutea are illustrated and discussed in terms of song characteristics, and a key is provided for the genus Palaeoagraecia. A new synonym is proposed: P. philippina (Karny, 1926)=P. globicerata (Vickery et Kevan, 1999) syn. nov.

  • The family Araneidae is a group of orb-weaving spiders and is one of the most diverse groups among the order Araneae. Eighty-one species belonging to 25 genera have been recorded in Korea to date. In this study, four araneid spiders in three genera, viz., Araneus mayumiae, Araneus ogatai, Cyclosa onoi, and Plebs baotianmanensis, were discovered for the first time in Korea. Additionally, Plebs yebongsanensis is removed from synonymy of Plebs sachalinensis, and treated as a new junior synonym of P. baotianmanensis, based on a morphological comparison of females of three Plebs species. Detailed descriptions of four species are provided with accompanying photographs.
