Computers and communication technologies have been brought tremendous change to various aspects of an ever-fast changing world at present. Particularly, the use of internet and cyberspace is widespread in every comer of our life. We developed a cyber shell museum using an animation technology. It was developed for educational purposes, and accessible through the world wide web of internet. Cyber shell museum is consisted of five compartment including rare shells, marvelous shells, shell of the world, the shell of Korea and its story of shells. The database contains the pictures and related information of the shell and it implies not only animation display but also text information. The files of database were classified depending on the species, genus, family, order, and class and division of the shell. Picture of shells is displayed and user may reach the image and virtual view information by clicking through the object displayed. This provides multiple techniques to user may manipulate, visualize and interact with image on the web. And every such transformation as translation, rotation, and scaling can be applied in the picture interactively for the convenient and effective viewing.

Although human rabies deaths are rare, the disease remains a public health problem in Korea. Here we report the outbreaks and surveillance of animal rabies in Gangwon-do. Animal rabies infections were identified in 119 animals from 1993 to 2003. The $78\%$ of all rabid animals were domestic species in Gangwon-do. Wild Korean raccoon dog (N. p. koreensis) continued to be the only reported rabid wildlife species. Outbreaks of rabies infections in Korean raccoon dogs are found in broad geographic regions across the northern Gangwon-do. The principal rabies hosts today are probably wild animals in Gangwon-do. The malaise, cerebral dysfunction, anxiety, confusion, agitation and abnormal behavior of the animals were the important symptoms of the disease. The Encephalitis, infiltration with lymphocytes and polymorphonuclear leukocytes and the inclusion bodies (Negri bodies) in neuronal cells were the specific histopathological signs. The results of indirect fluorescent antibody test (IFA) for animal rabies diagnosis were identical and the technique was useful to diagnose the disease. Preexposure vaccination is recommended for persons in high-risk groups, such as laboratory workers, veterinarians and certain animal handlers.

A scalp mass surgically excised from a 4-year-old Korean boy was identified as a tick through histological observations. In sections of the mass, characteristic features of a tick, including its gross contour, cuticular structures, well developed musculature and salivary glands, and the capitulum, were discovered. In particular, the capitulum is anteriorly protruded, which strongly suggests that the specimen be a hard tick of family Ixodidae. However, the pre-sent histological features were not enough to determine the genus and species of the tick, because information on sectional morphologies of different tick species is unavailable. This is a rare case of tick infestation on the scalp diagnosed in histological sections.

The purpose of this study was to evaluate the clinical utility of TB/NTM PCR by comparing the results of TB PCR to detect Mycobacterium tuberculous (MTB) and nontuberculous mycobacteria (NTM) from paraffin-embedded tissue specimens. A total of 60 cases were tested using TB PCR and TB/NTM PCR. The MTB and NTM rate of TB/NTM PCR was 84.2% (16/19), 10.5% (2/19) in TB positive of TB PCR. The NTM rate of TB/NTM PCR was 29.3% (12/41) in TB negative of TB PCR. Fourteen different species of NTM were identified, the common isolate was M. gordonae (21.4%), M. avium (14.3%), M. ulcerans (7.1%), M. interjectum (7.1%), M. gilvum (7.1%), M. fortuitum (7.1%), M. mucogenicum (7.1%). The rare species identified were M. farcinogenes (7.1%), M. tokaiense (7.1%). Therefore, TB/NTM PCR is useful to differentiate MTB and NTM from paraffin-embedded tissue specimens and it is more effective in detecting NTM with TB PCR.

A rat-fleas survey was carried out in Ducksonm and Kwangnaru areas of Seoul city from Janurary to December 1955 . In this survey, 1,204 redents were trapped alive and 740 of which being Rattus norvegicus, 457 Apodemus agrarius, 5 Eutamiias asiaticus and 2 shrewes ((crocidura rusila). On these rodents 270 fleas were collected and identified thus : Ceratopylidae : Monopsyllus anisus (Rothschild 1908) ···200 Leptosylla segnis(Schonherr, 1832)···1 Hystrichopsyllidae : Ctenophthalmus congener, Rothschild ···43 Neopsylla bidentiformis (Wagner, 1893)···11 Stenoponia sidimi Marikovsky, 1936···9 Pulcidae : Xenopsylla cheopis (Rothschild, 1903)···6 On the average 8.5% of the rodents were infestated with fleas. The infestation rate showed a marked varying degree in a year and three high incidence peaks in Spring (10.3%), Summer (11.4%-11.8%) and Winter (13.7%). The average number of fleas per rat (flea-index) was 0.22 for the whole year with a maximum of 0.41 in December and a minimum of 0.03 in February. Of all, the most prevalent species are Monopsyllus anisus (74.1%) and secondly Ctenophthalmus congener (15.9%). both species occupied 90% of all. Xenopsylla cheopis, a known vector of plague, was found very rare in our survey and only appeared in Winter. The striking lower incidence of flea-index compared with previous data (6.6 by Nagahana, 1931-1936) appears to be due to the nationwide application of DDT and BHC insecticides since 1945.

Text mining has become an important research method in biology, with its original purpose to extract biological entities, such as genes, proteins and phenotypic traits, to extend knowledge from scientific papers. However, few thorough studies on text mining and application development, for plant molecular biology data, have been performed, especially for rice, resulting in a lack of datasets available to solve named-entity recognition tasks for this species. Since there are rare benchmarks available for rice, we faced various difficulties in exploiting advanced machine learning methods for accurate analysis of the rice literature. To evaluate several approaches to automatically extract information from gene/protein entities, we built a new dataset for rice as a benchmark. This dataset is composed of a set of titles and abstracts, extracted from scientific papers focusing on the rice species, and is downloaded from PubMed. During the 5th Biomedical Linked Annotation Hackathon, a portion of the dataset was uploaded to PubAnnotation for sharing. Our ultimate goal is to offer a shared task of rice gene/protein name recognition through the BioNLP Open Shared Tasks framework using the dataset, to facilitate an open comparison and evaluation of different approaches to the task.

Chilean species of marine macroalgae with amphitropical distributions oftentimes result from introductions out of the Northern Hemisphere. This possibility was investigated using haplotype data in an amphitropical red macroalgae present in Chile, Callophyllis variegata. Published sequence records from Canada and the United States were supplemented with new collections from Chile (April 2014-November 2015). Specimens of C. variegata were amplified for the 5′ end of the cytochrome c oxidase subunit I gene (COI-5P) and the full length nuclear internal transcribed spacer region. Haplotype networks and biogeographic distributions were used to infer whether C. variegata was introduced between hemispheres, and several population parameters were estimated using IMa2 analyses. C. variegata displayed a natural amphitropical distribution, with an isolation time of approximately 938 ka between hemispheres. It is hypothesized that contemporary populations of C. variegata were established from a refugial population during the late Pleistocene, and may have crossed the tropics via rafting on buoyant species of kelp or along deep-water refugia coincident with global cooling, representing a rare case of a non-human mediated amphitropical distribution.

This study investigated the flora of the Wang-ime oreum located on Seogwipo-si, Jeju-do, to basic data for the Jeju Island plant distribution. A total of 366 taxa were found with 94 families, 240 genera, 358 species, 1 subspecies, 6 varieties, and 1 forma. The floristic target species in Korea appeared as 2 taxa of grade V, 13 taxa of grade IV, 46 taxa of grade III, 5 taxa of grade II, and 49 taxa of grade I. There were 14 taxa for naturalized plants. The different plant life forms that appeared were large ground plants (M)(54 taxa), small land plants (N) (52 taxa), epiphyte (E) (6 taxa), indicator plants (Ch) (4 taxa), and semi-aquatic plants (H) (168 taxa), There were 34 and 48 taxa of plants(G) and annuals (Th) respectively. From these results, Wang-ime oreum, which is adjacent to ranches and grasslands, has little artificial interference, as more plants are distributed, and fewer naturalized plants are found than in Suwolbong and Dangsanbong. Accordingly, each oreum plays an important role in the flora of Jeju-do, thus a management plan tailored to the characteristics of the volcano is necessary.

서낙동강의 물과 저토의 이화학적인 환경을 측정하고, 수생관속식물의 식생을 조사하였다. 수질은 수소이온농도, 용존산소, 엽록소a, 총질소 그리고 총인에 의하면 부영양화 상태이었으나 여름에는 지소에 따라 과영양 상태이었다. 수중 저토는 약산성 이었으며, 모래의 함량이 높았으나 SI는 점토, SU는 미사의 비율이 컸다. 수생식물 분포는 총 16과 26종 1변종으로 총 27분류군이었다. 지소별 우점종은 DU, GA 그리고 SU에서는 마름(Trapa japonica)이 우점하였고, DA에서는 노랑어리연꽃(Nymphoides peltata), SI는 자라풀(Hydrocharis dubia)이 우점하였다. SI와 SU에서 종다양도, 균등성이 높았으며, 우점도는 DA에서 높았다. 6월에 유입된 외래종 물상추(Pistia stratiotes)와 부레옥잠(Eichhornia crassipes)이 수역 전체에 확산되어 서낙동강 전체의 우점종이 되었다. 낙동강 하구둑 축조 당시와 비교하여 서낙동강에서 소멸된 종은 민나자스말(Najas marina), 톱니나자스말(Najas minor), 이삭물수세미(Myriophyllum spicatum), 어리연꽃(Nymphoides indica)이었다. 수생식물의 최대 현존량은 10월에 DU에서 가장 높았다(445g·Dw/㎡). 하구둑 축조당시인 1985년에 비하여 DU와 CA지소의 총현존량은 33.5%로 감소하였으며, 우점종 마름의 감소율이 56.7% 이었다. 종 수와 유사도 지수를 근거로 집괴분석한 결과에 따르면 GA-SU-DU, DA와 SI의 3집단으로 구분되어졌다. 외래종의 유입으로 인한 수생식물군락의 교란은 SI와 SU에 분포하는 가시연꽃(Euryale ferox)과 감소추세 종 자라풀을 포함하여 수역전체의 자생종들 특히 수금류의 먹이식물로 이용되는 마름, 나사말, 말즘 등의 감소를 초래하였다.
