SDS-PAGE of extracted surface-associated proteins of Lactobacillus rhamnosus strains E/N, Oxy, and Pen, was performed. The obtained protein patterns allowed differentiation of the examined strains, which was not accomplished by the commonly used RAPD genotypic method. The differentiation by the SDS-PAGE method proved to be a useful tool for strain-specific identification, which was further confirmed by 2DE analysis. Therefore, it can be used as an alternative or complementary method for both conventional and genotypic identification procedures, especially when closely related lactobacilli isolates are identified.

We investigated the cytogenetic characteristics of male black-striped field mouse (Apodemus agrarium) in Korea. Chromosome slides were obtained from blood cell cultures which were synchronized with thymidine blocking or not. In the chromosome slide which synchronization with thymidine blocking was employed on, the GTG(G bands by trypsin using Giemsa)-bands of high resolution were observed. The male black-striped field mouse has 48 chromosomes composed 46 autosomes and XY sex chromosomes. The centromeric regions of autosomes were positive to GTG-banding. According to this investigation, thymidine blocking in cell culture process was useful to get lengthened chromosomes. It may be necessary to employ RBG-banding technique to investigate complementary band patterns between R- and G-banding in black-striped field mouse.

Since its development in the early 70s, actigraphy has been widely used in sleep research and clinical sleep medicine as an assessment tool of sleep and sleep-wake cycles. The validation and reliability of actigraphic measures have been reasonably examined in healthy normal individuals with good sleep patterns. Recent literature suggests that the use of actigraphy could be further extended to monitor insomnia and circadian sleep-wake disturbances, and detect sleep changes associated with drug treatments and non-pharmacologic interventions, although it is generally recommended to use complementary assessments such as sleep diaries and overnight polysomnography when possible. The development of actigraphy includes its improved hardware sensors for better detection of movements and advanced algorithms to score sleep and wake epochs. In this paper, we briefly review the quantitative analysis methods of actigraphy and its potential applications in sleep research.

Many cultures have traditions that encompass the use of herbs, spices, and other plants for medicinal purposes. From the ancient past to the present medicinal knowledge has been passed down to new generations in the form of shamans, medicine men, healers, and the like. In the past decade there has been a surge of scientific interest in complementary and alternative medicine, much of which has its origins in traditional medicine. It has been recognized for some time that dietary patterns and content affect cancer risk. Epidemiological studies have strongly suggested that the fruit and vegetable content of the diet associates with reduced risk for colon, lung, prostate, and other cancers. Many different types of cellular mechanisms have been postulated by which compounds in botanicals can prevent cancer. Mechanisms particular to the prevention of colon cancer will be addressed in this review.

The problem of discovering association rules is an emerging research area, whose goal is to extract significant patterns or interesting rules from large databases and several algorithms for mining association rules have been applied to item-oriented sales transaction databases. Data warehouses and OLAP engines are expected to be widely available. OLAP and data mining are complementary; both are important parts of exploiting data. Our study shows that data cube is an efficient structure for mining association rules. OLAP databases are expected to be a major platform for data mining in the future. In this paper, we present an efficient and effective algorithm for mining association rules using data cube. The algorithm can be applicable to enhance the power of competitiveness of business organizations by providing rapid decision support and efficient database marketing through customer segmentation.

Multi-carrier waveforms have several advantages over single-carrier waveforms for radar communication. Employing multi-carrier complementary phase-coded (MCPC) waveforms in radar applications has recently attracted significant attention. MCPC radar signals take advantage of orthogonal frequency division multiplexing properties, and several authors have explored the use of MCPC signals and the difficulties associated with their implementation. The sidelobe level and peak-to-mean-envelope-power ratio (PMEPR) are the key issues that must be addressed to improve the performance of radar signals. We propose a scheme that applies pattern-based scaling and geometric progression methods to enhance sidelobe and PMEPR levels in MCPC radar signals. Numerical results demonstrate the improvement of sidelobe and PMEPR levels in the proposed scheme. Additionally, autocorrelations are obtained and analyzed by applying the proposed scheme in extensive simulation experiments.

The purpose of this study is to examine the relation between the trend of art and fashion which predominate a certain time. In order to achieve this goal, this study intends to analyze how plasticity found in Mondrian's pictures are applied to modern fashion with its focus on formative elements. Mondrian was ahead of abstractionism, a major trend of contemporary art, and defined the theory of neo-plasticism. The theory of neo-plasticism defined by Mondrian is characterized by the limited expression of lines and shapes by using only vertical and horizontal straight lines, and right angles and four-sided figures weaved by the lines, and the use of achromatic color(black, white, and gray) in three primary colors(red, blue, and yellow). Based on his theory, he fully displayed the world of geometric abstraction. Mondrian's formative elements which have been applied in modern fashion can be divided into shape and color, For the element of shape, first, horizontal and vertical lines have been applied to patterns, trimmings, detail, and plane of textiles through simplification of design, representing proportion, balance, and stress in a silhouette, Second, plane and diamond shapes made of horizontal and vertical lines have been applied to textiles or patterns with uniqueness. For the element of color, first, three primary colors and achromatic colors are used to seek the aesthetics of balance and harmony that are produced in the strain of conflict through brightness, chroma, and complementary colors, Second, primary colors of high chroma and brightness which are much stronger than pictures are used to express a modern sense. Formative elements of neo-plasticism, which have been applied to modern fashion suggested by this study, are connected with the trend of art contemporary designers have borrowed, Accordingly, this study will become a very helpful material which provides designers with original ideas in developing materials and patterns which connect design with art.

융통성 있는 소프트웨어 개발을 위해 많은 객체지향방법론들이 제공되어 지고 있으나, 이러한 객체지향방법론들은 자동적으로 재사용을 제공하거나 건실한 소프트웨어 시스템을 만들지 못하고 있다. 따라서 이러한 객체지향 방법론들은 개발자에게 상세한 설계지침을 제공하지 못하고 있으며, 분석·설계자들로 이런 문제점들을 인정하고 방법론들을 향상시켜 나가려고 노력하고 있다. 이와 같이 분석·설계자들의 노력을 줄여 주면서 설계단계의 정보를 재사용할 수 있도록 제공하고자 하는 것이 설계패턴의 개념이며, 이러한 설계패턴과 객체지향 방법론은 상호 보완적인 관계를 가지면서 시스템을 개발하는데 유용한 설계 길잡이의 역할을 한다. 이에 본 논문에서는 객체지향 방법론 중에서 가장 많이 다루어지고 있는 OMT 방법론과 Gamma가 제안한 설계패턴 중 Facade, Mediator, Observer의 세 가지 설계패턴에 대한 상호작용을 보여주고, OMT방법론 내에 설계패턴을 적용함으로써 구체적인 설계지식과 재사용에 대한 명확한 해법을 제안한다.

The grid-based analysis is useful for conservation planning, species distribution study, education, and others'. On the west coast of Korea, it was high in species richness, rarity and endangered species richness. Our results also showed that coordinated species data can be applied to develop species distribution models due to the high correlation between total species richness and coordinated species 0richness. In hot spot analysis, high species richness areas are concentrated around the west coast, while species richness is relatively low in Gangwon and Gyeongnam. Endangered species and rarity were also concentrated on the west coast and islands. Through the complementary analysis, we selected areas which are efficient to protect species; protecting more species while minimizing the conservation effort. Our result demonstrated that simply protecting Baengyueong island, Gageo island and a part of Jeju island can conserve over 50% of bird species in South Korea. However, the validity of our analysis was limited by the absence of data from national parks, and Baekdudaegan protected areas as well as inconsistent capacity among field researchers.
