The problem of phlebothrombosis is an important one, not only because of its local effects, but because of the propensity for portions of the venous clot to berak off and travel back to the heart and into the pulmonary Artery. The result of pulmonary embolism, unfortunately is still as prominent a cause of death today as it was before the advant of modern advances in treatment and prevention. This paper reports a case of thrombosis of left common iliac vein left hypogastric vein and left common femoral vein, who had been bedmidden for two weeks because of left knee joint arthritis. Successfully treated with transabdominal direst venous thrombectomy and anticoagulant heparin. Authors also reviewed the references.

Culture-independent approaches, based on 16S rDNA sequences, are extensively used in modern microbial ecology. Sequencing of the clone library generated from environmental DNA has advantages over fingerprint-based methods, such as denaturing gradient gel electrophoresis, as it provides precise identification and quantification of the phylotypes present in samples. However, to date, no method exists for comparing multiple bacterial community structures using clone library sequences. In this study, an automated method to achieve this has been developed, by applying pair wise alignment, hierarchical clustering and principle component analysis. The method has been demonstrated to be successful in comparing samples from various environments. The program, named CommCluster, was written in JAVA, and is now freely available, at http://chunlab.snu.ac.kr/commcluster/.

In Modern society, various important systems is operated such as nuclear plant, chemistry industry, railway system and so on. But these systems can cause high risky accidents. Hence, these systems are required to ensure the individual and societal risk criteria. In this paper, we reviewed EU risk criteria which is already operated in UK and Netherlands, then we proposed acceptable risk criteria and estimated risk of oil immersed transformer for subway with FN curve.

It has been proposed since modern times that we need to consult the history of mathematics in teaching mathematics, and some modifications of this principle were made recently by Lakatos, Freudenthal, and Brousseau. It may be necessary to have a direction which we consult when modifying the history of mathematics for students. In this article, we analyse the elements of the cognitive interest in Hamilton's discovery of the quaternions and in the history of discovery of imaginary numbers, and we investigate the effects of these elements on attention of the students of nowadays. These works may give a direction to the historic-genetic principle in teaching mathematics.

In November of 1994, The Seoul Metropolitan Government celebrates its sixth centennial anniversary of becoming the capital city of Korea. In celebration of this anniversary, the Government decided to construct a plaza and sought design proposals in March of 1994. The authors collaborated on a design for the Time Capsule Plaza Competition and won fourth place among twenty-six entries. In the authors' design, the traditional oriental concept of time resonates within the site through the shape of a clock, a unique planting style, and an "Ancestral Tomb" which has a time capsule inside. The plaza is meant to be a symbol of the passage of time, the cycles of nature, and the repetitive actions of man. As for the spatial composition of the plaza, in accordance with the traditional Korean way of spatial arrangement, the plaza is divided into three parts: entry, primary, and secondary spaces. In reality, the plaza is created with the primary goal of providing modern outdoor space for people to rest and gather through the creation of pleasant environments and the introduction of traditional Korean garden elements.

Characteristics of precipitation in Seoul have been examined by using long-term observational data. Precipitation records from modern rain gauges were used for 1908-1996, together with the traditional Korean rain gauge (called Chukwookee) observations for 1777-1907. A linear trend analysis of seasonal total rainfall shows no significant trends over the last 200 years A wavelet transform analysis was performed to figure out the transient variations of precipitation.

The Korean government has recently announced its plan to establish the first National Museum of Natural History. However, the Korean word for natural history, jayonsa, is not a very familiar term to some academics as well as the general public. This article discusses the definition and history of natural history, describes the functions of natural history meseums, and makes suggestions to the establishment of our National Museum. Modern natural history is no longer an art of ‘stamp collecting’. It is a comprehensive scientific endeavor pursuing to enlighten the history of the planet Earth and the diversity of natural objects it contains. Natural history museum must have two museums within the museum: the outer museum for exhibition and general public education and the inner museum for research and specialist education. I hope that our National Museum of Natural History will be a place where we all get to know about Nature and thus to love her.

Post-transcriptional nucleotide sequence modification of transcripts by RNA editing is an important molecular mechanism in the regulation of protein function and is associated with a variety of human disease phenotypes. Identification of RNA editing sites is the basic step for studying RNA editing. Databases and bioinformatics resources are used to annotate and evaluate as well as identify RNA editing sites. No method is free of limitations. Correctly establishing an analytic pipeline and strategic application of both experimental and bioinformatics methods constitute the first step in investigating RNA editing. This review summarizes modern bioinformatics approaches and related resources for RNA editing research.

Modern public library is expanding its role as generalized cultural facility. Therefore public library that has comfortable and physical environment for various age and various users are needed. The purpose of this research is to evaluate the application of universal design in common space of public library, and trying to suggest environmental improvement plan that various users could comfortably use the library based on its data. The scope of this research were adjusted as 8 public libraries located in Seoul and metropolitan area of Seoul. Spacial scope that was set of this research was common space of public library and scope of content was about application of universal design. As a result of the research, first, the application of universal design toward common space of public library were appeared as low. Second, constant management and application development of universal design is needed. Third, as roles and functions of public library become various from now on, application of delicate universal design is needed for intention of users.

The most distinctive feature of the costumes of the Arctic regions from Alaska to Siberia centering around the Bering Sea connecting Asia to North America, is that each tribe makes clothes adequate to the climate and their lifestyles with animal hides obtained from hunting in their habitation. Furs or fish skins, the main materials for clothing, are characteristically cut into many pieces, and thus piece-joining patchwork is used to make or decorate garments. Patchwork is the technique that can create new designs with 3-dimensional and various combinations by modifying the simple materials, and also has the advantage of fitting the body without a certain cut line. Therefore, the patchwork found in the Arctic costumes may be developed from folk costume designs with limited materials like fur into new ones for modern or future costumes.
