A visual field tester using a fixation target with a lack of distinctiveness decreases accuracy and usability in visual field testing. The present study is intended to develop various induction methods of gaze fixation for effective visual field testing. Proposed were four new gaze fixation induction methods (color changing dot; alphanumeric characters; flashing black dot; and bulls eye and cross hair, BECH) by considering visual attention factors such as color, meaning, flashing, and shape and the proposed methods were compared with the existing black dot (BD) method in terms of gaze fixation performance and subjective satisfaction by 32 participants in their 20s to 30s. BECH was found most preferred by increasing gaze fixation performance by 4.8% and subjective satisfaction by 0.4 to 2.0 in a 7-point scale compared to BD. BECH can be applied to tests such as visual field testing and macular pigment optical density testing in which gaze fixation is crucial for accuracy and usability.

In order to isolate thermophilic bacteria with high activity of CMCase and xylanase, spent mushroom substrates was collected from an oyster mushroom cultivation farm in Jinju, Gyeongnam, Korea. Among the isolates, one strain designated as YJ09 was selected by agar diffusion method. The isolate YJ09 was identified as a member of Bacillus licheniformis based on biochemical characteristics using Bacillus ID kit and MicroLog system. Comparative 16S rDNA sequence analysis showed that isolate YJ09 formed a distinct phylogenetic tree within the genus Bacillus and was most closely related to Bacillus licheniformis with sequence similarity of 98.9%. Based on its physiological properties, biochemical characteristics and phylogenetic distinctiveness, the isolate YJ09 was classified as Bacillus licheniformis. The CMCase and xylanase activity of B. licheniformis YJ09 was slightly increased corresponding to the bacterial population from exponential phase to stationary phase in the growth curve of B. licheniformis YJ09.

A Gram-negative, strictly aerobic, motile bacterial strain, designated Gsoil $124^T$, was isolated from a soil sample taken from a ginseng field in Pocheon Province (South Korea). The isolate contained Q-10 as the predominant lipoquinone, plus $C_{18:1}\;{\omega}7c$ and summed feature 4 ($C_{16:1}\;{\omega}6c$ and/or iso-$C_{15:0}$ 2-OH) as the major fatty acids. The G+C content of the genomic DNA was 68.1 mol%, and the major polar lipids consisted of sphingoglycolipid, phosphatidylglycerol, phosphatidylcholine, and phosphatidylethanolamine. A comparative 16S rRNA gene sequence analysis showed that strain Gsoil $124^T$ was most closely related to Sphingopyxis chilensis (98.7%), Sphingopyxis alaskensis (98.2%), Sphingopyxis witflariensis (98.2%), Sphingopyxis taejonensis (98.0%), and Sphingopyxis macrogoltabida (97.6%). However, the DNA-DNA relatedness between strain Gsoil $124^T$ and its phylogenetically closest neighbors was less than 22%. Thus, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil $124^T$ should be classified as representing a novel species in the genus Sphingopyxis, for which the name Sphingopyxis panaciterrae sp. nov. is proposed. The type strain is Gsoil $124^T$ (=KCTC $12580^T$=LMG $24003^T$).

A Gram-negative, strictly aerobic, nonmotile, and nonspore-forming bacterial strain, designated $T5-12^T$, was isolated from compost and characterized using a polyphasic taxonomical approach. The isolate was positive for catalase and oxidase tests. It could degrade DNA, but was negative for degradation of macromolecules such as casein, collagen, starch, chitin, cellulose, and xylan. The DNA G+C content was 36.0 mol%. The predominant isoprenoid quinone was menaquinone 7 (MK-7). The major fatty acids were $iso-C_{15:0}$ (45.6%), $iso-C_{17:0}$ 3OH (17.2%), and summed feature 4 ($C_{16:0}\;{\omega}7c$ and/or $iso-C_{15:0}$ 2OH, 14.9%). Comparative 16S rRNA gene sequence analysis showed that strain $T5-12^T$ fell within the radiation of the cluster comprising members of the genus Sphingobacterium. Strain $T5-12^T$ exhibited lower than 94% of 16S rRNA gene sequence similarity with respect to the type strains of recognized Sphingobacterium species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain $T5-12^T$ ($=KCTC\;12578^T=LMG\;23401^T=CCUG\;52467^T$) should be classified in the genus Sphingobacterium as the type strain of a novel species, for which the name Sphingobacterium composti sp. novo is proposed.

A Gram negative, aerobic, nonspore-forming, straight or curved rod-shaped bacterium, designated Gsoil $317^T$, was isolated from soil of a ginseng field in Pocheon Province (South Korea) and was characterized using a polyphasic approach. Cells were dimorphic, with stalk (or prostheca) and nonmotile or nonstalked and motile, by means of a single polar flagellum. Comparative analysis of 16S rRNA gene sequences revealed that strain Gsoil $317^T$ was most closely related to Caulobacter mirabilis LMG $24261^T$ (97.2%), Caulobacter fusiformis ATCC $15257^T$ (97.1 %), Caulobacter segnis LMG $17158^T$ (97.0%), Caulobacter vibrioides DSM $9893^T$ (96.8%), and Caulobacter henricii ATCC $15253^T$ (96.7%). The sequence similarities to any other recognized species within Alphaproteobacteria were less than 96.0%. The detection of Q-10 as the major respiratory quinone and a fatty acid profile with summed feature 7 ($C_{18:1}\;{\omega}7c$ and/or $C_{18:1}\;{\omega}9t$ and/or $C_{18:1}\;{\omega}12t;$ 56.6%) and $C_{16:0}$ (15.9%) as the major fatty acids supported the affiliation of strain Gsoil $317^T$ to the genus Caulobacter. The G+C content of the genomic DNA was 65.5 mol%. DNA-DNA hybridization experiments showed that the DNA-DNA relatedness values between strain Gsoil $317^T$ and its closest phylogenetic neighbors were below 11%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil $317^T$ should be classified as representing a novel species in the genus Caulobacter, for which the name Caulobacter ginsengisoli sp. novo is proposed. The type strain is Gsoil $317^T$ (=KCTC $12788^T=DSM\;18695^T$).

In this paper, we propose a fast object classification method based on texture and color information for video surveillance. We take the advantage of local patches by extracting SURF and color histogram from images. SURF gives intensity content information and color information strengthens distinctiveness by providing links to patch content. We achieve the advantages of fast computation of SURF as well as color cues of objects. We use Bag of Word models to generate global descriptors of a region of interest (ROI) or an image using the local features, and Na$\ddot{i}$ve Bayes model for classifying the global descriptor. In this paper, we also investigate discriminative descriptor named Scale Invariant Feature Transform (SIFT). Our experiment result for 4 classes of the objects shows 95.75% of classification rate.

The aim of this study is to understand the effects of a social capital discovery program on career identity and empowerment in adolescents under probation. As a result, it was discovered that the social capital discovery program had statistically significant differences in stability, goal orientation, distinctiveness and self-presence consciousness in the sub-area of career identity in adolescents under probation while there was no significant difference in the area of self-assertion. The social capital discovery program had statistically significant differences in internal and personal relationships among the sub-area of empowerment of the subjects while there were no significant differences in political-social areas. These results suggest that the social capital discovery program had significant effects on career identity and empowerment in adolescents under probation. In order to improve the career identity and empowerment in adolescents under probation, further studies on the social capital discovery program are needed and care should be paid to its usability.

Photography has been used as a typical tool of recording image since its invention in the nineteenth century. Photographs provide valuable visual information about all parts of society, and a systematic management must be preceded to use these information. The management and preservation system of photographs should reflect the characteristics of photographic medium. It is necessary for many archives to perform appraisal first to collect and manage enormous photographs. Appraisal is the process of determining meaning and value of records, and the reasonable criteria should be needed to carry it out. The purpose of this study is to suggest appraisal criteria for photographic records based on the archival appraisal theories and the characteristics of photography. This study draws on traditional appraisal theories and some literatures for archival management of photographs. This study is organized as follows. The first section examines the concept and values of photographic records and the distinctiveness of appraising photographs. The second section analyzes the existing appraisal criteria for individual records. The third section designs appraisal classes of photographic records and proposes the criteria for each classes.

This study focuses on the analysis of Baudelaire's aesthetic perspective which has established a theoretical basis on research of the critical reviews' salon exhibitions as written by Baudelaire. Charles Pierre Baudelaire(1821-1867) having lived during the latter part of Neo-classicism and the era of Romanticism and Impressionism, Baudelaire displayed opposition to customary realities such as social ideology or religious authority that suppressed human nature. Also he pioneered a new genre known as art criticism and wrote much that provided important insights on the essential elements of artistic work, modernity and trend, as well as art definition and art categories. The aesthetic perspective and creative spirit were formed by Baudelaire, during his age were also reconfirmed in the successive ages of modernism and postmodernism. As such, this study sheds light on how Baudelaire's aesthetic perspective was not only temporarily assertion but it is consistently applied to modern art and fashion area. What is more important that, Baudelaire admired new artificial beauty that is created by the human soul liberated from natural instincts or desires. Especially, informed by strangeness and distinctiveness, Baudelaire's view of fashion ran along the same vein as his view of art, and these views form the basis of that creative spirit which situated western fashion on a center of the world. In conclusion, the research on Baudelaire's aesthetic perspective will reaffirm a firm awareness of the creative spirit essential to globally-oriented creative artists and designers who work within the circumstance of the 21st century, a time when the paving of new aesthetic paths is necessary. The research also offers a clear understanding of the aesthetic values demanded by this age.

Background: DNA repair is one of the crucial defense mechanism against mutagenic exposure. Inherited SNPs of DNA repair genes may contribute to variation in DNA repair capacity and susceptibility to cancer. Due to the presence of these variants, inter-individual and ethnic differences in DNA repair capacity have been established in various populations. India harbors enormous genetic and cultural diversity. Materials and Methods: In the present study we aimed to determine the genotypes and allele frequencies of XRCC1 Arg399Gln (rs25487), XRCC3 Thr241Met (rs861539), XPD Lys751Gln (rs13181), and OGG1 Ser326Cys (rs1052133) gene polymorphisms in 186 healthy individuals residing in the Hyderabad region of India and to compare them with HapMap and other populations. Results and Conclusions: The genotype and allele frequency distribution at the four DNA repair gene loci among Hyderabad population of India revealed a characteristic pattern. Comparison of these gene polymorphisms with other populations revealed a distinctiveness of Hyderabad population from the Deccan region of India. To the best of our knowledge, this is the first report of such DNA repair gene polymorphisms in the Deccan Indian population.
