Query reformulation is an interactive process of revising user queries according to the query results. To assist biomedical researchers in this process, we present novel methods for automatically generating query reformulation suggestions. While previous work on query reformulation focused on addition of words to user queries, our method can deal with three types of query reformulation (i.e., addition, removal and replacement). The accuracy of the method for the addition type is ten times better than PubMed's "Also try", while the execution time is short enough for practical use.

Repetitive sequences such as SINE, LINE, and LTR elements form a major part of eukaryotic genomes. A literature search tool that summarizes the information contained within repeat elements would provide biologists in the field of genomics with a useful tool for analyzing genomic sequence features. We developed a java program designed to make literature access easier by using two search engines simultaneously. RepWeb is a web-based search system that provides a user friendly interface for searching the reference data and journals for information related to repeat elements by using the search engines, Google Scholar and PubMed, simultaneously. It provides an interface that displays the repeat element- related biological information, and includes useful functions such as the production of a repeat tree, clickable links to PubMed and Google Scholar, exporting, and sorting a field into date, author, journal and title.

In this paper we introduce PubMiner, an intelligent machine learning based text mining system for mining biological information from the literature. PubMiner employs natural language processing techniques and machine learning based data mining techniques for mining useful biological information such as protein­protein interaction from the massive literature. The system recognizes biological terms such as gene, protein, and enzymes and extracts their interactions described in the document through natural language processing. The extracted interactions are further analyzed with a set of features of each entity that were collected from the related public databases to infer more interactions from the original interactions. An inferred interaction from the interaction analysis and native interaction are provided to the user with the link of literature sources. The performance of entity and interaction extraction was tested with selected MEDLINE abstracts. The evaluation of inference proceeded using the protein interaction data of S. cerevisiae (bakers yeast) from MIPS and SGD.

본 논문은 전자책 제작 Sigil 환경과 C 프로그램 환경을 이용하여 전자책 ePub과 서버, 클라이언트 통신을 통해 인증정보를 사용한 전자책의 저작권 보호 시스템을 설계한다. 서버와 클라이언트 통신을 통해 전자책의 인증정보를 이용하여 사용 권한 유무를 판별한다. 나날이 불법적인 방법으로 전자책을 구입하는 경우 저작권의 보호를 받지 못해 큰 피해를 입는 사람들이 많다. 본 논문은 전자책 ePub의 인증정보를 이용한 저작권 보호 프로그램을 개발하여 전자책의 인증정보가 조건에 만족한다면 전자책을 열람하고, 조건에 만족하지 않는다면 프로그램을 종료함으로서 악의적인 사용자가 전자책의 접근을 할 수 없도록 한다.

In this paper, we propose the development of an eBook Service System based on VOD Broadcasting Contents(eBSS-VOD) which protects the illegal copy through the effective DRM strategy. Here, eBSS-VOD is composed of three sub-systems - eBook server management system, ePub Builder, and eBook App - according to the functional points of view. The eBook server management system operates to manage the eBooks, the encription keys, the VOD contents, the membership and the history of users' viewing log. The ePub Builder assists to produce eBooks by DRM strategy. The eBook App provides users with the utility services of VOD viewing and eBook purchase processing. The proposed eBSS-VOD, differently from the current eBook systems, helps to increase the users' interests in reading books and to motivate the users' purchasing needs and it also makes new distribution channel for eBooks based on VOD broadcasting contents through smart applications. We provides the differentiated eBook builder which are based on ePub3.0 and DRM strategy. Through empirical survey results on users' interests and purchase intention for eBooks, we show that the proposed eBSS-VOD has the comparative effects compared to the current systems.

Acute and chronic responses to PCB toxicity of Neomysis awatschensis were studied by measurement of bioassay, growth, oxygen consumption and nitrogen excretion with concentrations of PCB at 10 and $20^{\circ}C$. 96 hr.-$LC_50$ at 10 and $20^{\circ}C$ were 28.7492 pub and 10.6742 pub, respectively. Survival rates during 60 days exposured to chronic PCB concentrations of 0.5 pub, 1.0 pub, 1.5 pub and 2,0 pub at $10^{\circ}C$ were $85\%,\;80\%,\;75\%$ and $75\%$, respectively and suwival rates at $20^{\circ}C$ $85\%,\;75\%,\;75\%$ and $65\%$, respectively. Average daily growth rate of N. awatschensis exposed to chronic PCB concentrations at $10^{\circ}C$ were 0.039 mm/day in control group and 0.036 mm/day at concentration of 2.0 ppb, while their rates at $20^{\circ}C$ showed 0.072 mm/day in central group and 0.039 mm/day at 2,0 ppb. The growth factors were some similarities between the chronic PCB concentrations, but intermolt periods were related to body size of mysids, temperature and PCB toxicity. Changes in oxygen consumption and nitrogen excretion rates during 60 days exposure to PCB toxicity showed higher in high groups of PCB concentrations. Assimilation and feeding rates of N. awatschensis fed Artemia sp. decreased with increase of PCB concentration at 10 and $20^{\circ}C$.

정보시스템의 보호를 위한 정보보호 제품의 경우, CC를 바탕으로 하는 '정보보호시스템 평가제도'를 통해 평가 및 인증하며, 정보보호제품을 구현한 암호모듈의 경우, '암호모듈검증제도'(CMVP)를 통해 시험 및 검증한다. 본 글에서는 사실상의 국제기준인 미국 및 카나다의 CMVP의 새로운 검증기준 후보인 FIPS PUB 140-3의 변화내용을 분석한다. 또한, FIPS 140-1, FIPS 140-2, ISO/IEC 19790(즉, FIPS 140-2의 국제표준)의 내용과도 비교한다.
