The induced genetic divergence was estimated in 44 mutant lines of finger millet variety GPU 26, developed by single and combination treatments with gamma rays, EMS and NG using three multivariate analyses. The mutant lines were grouped into eight genetically diverse clusters by multivariate D2 and canonical analyses and 11 clusters by dendrogram grouping through Gower's similarity coefficient. The clustering pattern in these three methods was almost similar. Twelve mutant lines in D2 and 13 in the dendrogram grouping method were grouped in the parental cluster(Cluster I) indicating that they did not possess enough divergence from the parent to be classified as micromutant lines. However a large proportion of mutant lines showed divergence from the parent variety and also among themselves. No definite relationship of mutagenic origin and clustering of mutant lines were observed. The mutant lines developed from the same mutagenic treatments often grouped into different clusters indicating that each mutagenic treatment was effective in inducing diverse types of changes in the nine traits studied. The hybridization program between the divergent mutant lines GE 2-2 or GE 3-4 with GG 3-1 is expected to give promising and desirable segregants in subsequent generations. Traits such as days to 50% flowering and days to maturity had major contributions to the induced genetic divergence.

This study evaluated how folly is experimented in the contemporary architecture after 30 years when Bernard Tchumi first introduced it to the public by the modern transformation as a garden ornament. First, folly project has been carried out based on the general concept of energizing dwindling cities. However, it has changed to the direction of adding specific programs. Also, along urban regeneration that does not change deterioration of previous structures, Folly changed in the emphasis on readjust existing structure. Second, by having different designers presenting their own follies during the Osaka Expo, folly now has part on visual exhibition element. This has similarity with public art project, yet it could more actively intervene for urban regeneration compared to conventional environment sculpture. Third, folly is experimented as the event-installation art combined form of architecture and art where people could experience the space and enjoy art. Fourth, folly enabled the landscaping of architecture and expanding city planning. Recently Gwangju Folly invited various arts, social, and cultural professionals to converge city design with architecture, landscaping, and other diverse genres.

In the modern society, the crossover phenomenon has appeared increasing the value of creative brands as concepts contrary or heterogeneous are combined with each other by the flow of diversified societies and cultures. This research covers the use of crossover design in current fashion. To analyze the crossover design in current fashion, crossover design were collected and analyzed from a Collection TV program(Seoul: Dong Ah TV) and an Internet Web site(www.samsungdesign.net) from 2007 to 2010. The information obtained from the current fashion is compared with the advertisement area; by making this comparison we will make an analysis to determinate the crossover elements organized in 5 groups: extension and reduction, breakaway and destruction, fusion and combination, overlap and repetition, adjacent and similarity. This 5 crossover elements were analyzed in current fashion with the purpose of seeing how crossover elements are available in fashion field. Therefore, this study can offer invaluable suggestions for multifaceted research on how to come up with design concepts which apply crossover element to current fashion.

Vowels are classified by the shapes of vocal tract. These shapes form constriction points along the tract, which have an influence on such vocal tract resonance as F1, F2, F3, and so on. The formant frequency is influenced by aperture and placement of tongue and the intensity is influenced by air pressure of subglottis. The object of this study compares to characterize the spectral outputs of oral and nasal spectra for the formant frequencies and intensity of Korean oral vowels. Subjects consisted of 20 normal persons (10 male and 10 female) without laryngeal pathology. The speech sample included /a/, /e/, /i/, /o/, /u/ of Korean oral vowels. The spectrum of each vowel was analysed by Nasal View and Real Analysis Program using Dr. Speech. The result showed that nasal intensity is decreased manifestly from F1 to F2. But oral intensity and Intensity is decreased little bit from F1 to F2. The most of values of nasal formant frequency is similarity oral formant frequency and Formant frequency or little bit smaller.

Pregnant women need to be supported by their husbands and other family members. But little is known about the factors that contribute to perceived support in pregnant women. So this study is designed to identify the factors contributing to perceived support in pregnant women. The subjects for this study were 19 women who had had vaginal deliveries and 11 who had had cesarean sections in one hospital affiliated with a university. Data were collected during July and August 1992 through interview which lasted 20~30 minutes and used open ended questions. Each woman was interviewed once about their pregnancy experience. The data were analyzed by Van Kaam’s phenomenological analysis method and categorized accord-ing to similarity of content. Results of this study are as follows. 1) Mothers felt physically supported by having help with their activities from their husbands or other family members. Psychological stress was relieved by not having to worry about and / or giving a birth to a baby boy ; getting special attention : and hearing encouraging words. 2) Mothers felt not supported when indifference was shown by her husband and / or relatives ; when forced to do an unusual household activities ; or on hearing words stressing her responsibilities. Suggestion for further study are as follows. It is necessary to see if or not the contents of an educational program would increase the perceived support of pregnant women. This could be done by carrying out an experimental research project.

The purpose of his study was to investigate the effectiveness on clothing advertisement of three types of model, perception of model attributes by the clothing consumers, and difference in advertisement effectiveness according to perception of model attributes. Three types of advertisements for easy casual brand were selected, which are using celebrity, expert and general consumer models. The final analysis included 304 persons, who ranged from 16 to 25 in age. The statistics used analysis include ANOVA, Duncan's multiple range test, factor analysis and regression by the SPSS program. The result were as follow:1. The celebrity advertisement was the most effective type on all kinds of attitude changes (cognitive, emotional, and behavioral attitude changes) of consumers.2. The celebrity model received high scores on attractiveness and truthfulness; and the general consumer model received high scores on truthfulness and similarity.3. The amount of consumers attitude changes was different according to the perceptions of model attributes as well as the types of model.

As part of the research program "2018 Rapid screening and identification of freshwater microorganisms using MALDI-TOF/MS library" freshwater samples were collected from a branch of the Nakdong River. Almost 300 antibiotic-resistant bacterial strains were isolated from freshwater samples and subsequently identified by 16S rRNA gene sequencing. Seventeen strains among the isolates shared high 16S rRNA gene sequence similarity (>99.0%) with known species that were not previously recorded in Korea, and each of the isolates also formed a robust phylogenetic clade with the closest species. These species were phylogenetically diverse, belonging to four phyla, seven classes, 10 orders, and 13 genera. At the genus and class level, the previously unrecorded species belonged to Rhodovarius, Xanthobacter, and Shinella of the class Alphaproteobacteria; Ottowia, Simplicispira, and Zoogloea of Betaproteobacteria; Pseudomonas, Acinetobacter, and Shewanella of Gammaproteobacteria; Arcobacter of Epsilonproteobacteria; Sphingobacterium of Sphingobacteriia; Trichococcus of Bacilli; and Leucobacter of Actinobacteria. The previously unrecorded species were further characterized by examining their gram-staining, colony and cell morphology, biochemical properties, and phylogenetic position.

Prestress force identification (PFI) is crucial to maintain the safety of prestressed concrete bridges. A synergic identification method has been proposed recently by the authors that can determine the prestress force (PF) and the excitation force simultaneously in prestressed concrete beams with good accuracy. In this paper, the ability of this method in the application with prestressed concrete box-girder bridges is demonstrated. A reasonable assumption is made to capture the similarity of the dynamic behavior of the prestressed concrete box-girder bridge and a beam under a certain loading scenario, and the feasibility of this method for application in a prestressed box-girder bridge is affirmed. A comprehensive laboratory test program is conducted, and the effects of PF, excitation, measuring time and uncertainties are studied. Results show that the proposed method can predict the PF and the excitation force in a prestressed concrete box-girder accurately and has a great robustness against uncertainties.

An Internet worm is a self-replicating malware program which uses a computer network. As the network connectivity among computers increases, Internet worms have become widespread and are still big threats. There are many approaches to model the propagation of Internet worms such as Code Red, Nimda, and Slammer to get the insight of their behaviors and to devise possible defense methods to suppress worms' propagation activities. The influence of the network characteristics on the worm propagation has usually been modeled by medical epidemic model, named SI model, due to its simplicity and the similarity of propagation patterns. So far, SI model is still dominant and new variations of the SI model, called SI-style models, are being proposed for the modeling of new Internet worms. In this paper, we elaborate the problems of SI-style models and then propose a new accurate stochastic model using an occupancy problem.
