The purposes of this study are to investigate Korean mathematics & science teachers' perception on the special education for the gifted, and to investigate if there are differences on their perception about it among the mathematics & science teachers when their affiliation institutes for the gifted are different. Their affiliation institutes for the gifted education are divided into two groups, which are the city office of education, and science high school. The research problems of this study are as follows. Firstly, are there any differences of their perception according to their affiliation institutes for the gifted education are divided into two groups, which are the city office of education, science high school? Secondly, are there any differences of their perception according to their affiliation institutes for the gifted education are divided into two groups, which are the mathematics teachers, science teachers? For the study, 26 mathematics teachers & 36 science teachers were sampled from the Institutes for the Gifted Education in Busan Metro-city & the Busan Science High School. and then 34-item-questionnaire developed by the author was administered to them. The research results are as follows. Firstly, the question as to participation in special education for the gifted in mathematics & science, the positive answer has been dominant. Teachers who were going to participate in special education for the gifted in mathematics & science have answered affirmatively. Secondly, perception of the organization of a class of the gifted in mathematics & science is very different between the group of institutes for the gifted education in the city office and the group of institutes for the gifted education in the science high school.

Several marine bacterial strains were isolated from Undaria pinnatifida (Miyok in Korean). Sixty-six strains were isolated on R2A agar media at $10^{\circ}C$ and identified by a phylogenetic analysis of the 16S rRNA gene sequences. They were grouped into 10 different sequence types based on the initial sequence analysis of the 5' domain of the gene (approximately 500 bp). Full sequences of 16S rRNA gene, were obtained from one strain in each sequence type and the species-affiliation was determined using phylogenetic and sequence similarity analyses. The results of the analyses indicated that they were closely related to Psychrobacter aquimaris, P. celer, P. nivimaris, P. pulmonis, Psychromonas arctica or Bacillus psychrodurans. These bacteria are marine or psychrotrophic bacteria. Because the sporophytes of U. pinnatifida are cultured on the costal area during winter, the U. pinnatifida-associated bacteria appeared to grow at low temperatures. U. pinnatifida sporophytes can be a good source for the isolation of psychrotrophic bacteria.

Many empiric research findings have supported that the characteristics and strength of Organization Culture(OC) is closely related with organizational performance(absenteeism, job satisfaction, cohesiveness and turnover etc.). The first purpose of this study is to review the relationship between OC and turnover as a performance factor, and the second and primary purpose is to test the moderating effects of personal factors(sex, educational career, rank, occupation, marital status, job switching, age, company tenure and job tenure) between OC and turnover. For the analytical purpose of this article, OC type is categorized as Maintainable Culture(MC), Affiliation Culture(AC), Progressive Culture(PC) and Rational Culture(RC) based on Quinn(1985). The empirical results are as followings: Moderating effects are found in sex(with MC and RC), educational career(with MC, PC and RC), job switching(with MC and RC).

The algorithm of customer demand decomposition suggested by this study is a reconstruction method of distribution network under the allowance of same level supply. Regional distribution center(RDC) distributes additional inventories of some of the supplying items to retailers under its charge to reduce the time needed for emergency delivery to neighborhood retailer where backlog happened. This also restrict the purpose of the inventories held by RDC as only regular supply. All of which leads to the creation of more realistic method allowing the affiliation of closing related RDC with one in the vicinity. In this study, the role of RDC is restricted only as supplying items regularity and the conruction of distribution system processing through the closing by consideration of the possibility of supplying retailers from the RDC in the vicinity is discussed.

Poly-Si TFT(Thin Film Transistor) technology are reviewed and discussed. Poly-Si TFTs fabricated on glass using low-temperature process were studied extensively for the application to LCD (Liquid Crystal Display) as well as to OLED(Organic Light Emitting Diode) Display. Currently, one of the application targets of the poly-Si TFT is emphasized on the highly functional SOG(System on Glass). Improvement of device characteristics such as an enhancement of carrier mobility has been studied intensively by enlarging the grain size. Reduction of the voltage and shrinkage of the device size are the trend of AM FPD(Active Matrix Flat Panel Display) as well as of Si LSI, which will arise a peculiar issue of uniformity for the device performance. Some approaches such as nucleation control of the grain seed or lateral grain growth have been tried, so far.

Social network analysis is a graphical technique to search the relationships and characteristics of nodes (people, companies, and organizations) and an important node for positioning a visualized social network figure; however, it is difficult to characterize nodes in a social network figure. Therefore, their relationships and characteristics could be presented through an application of correspondence analysis to an affiliation matrix that is a type of similarity matrix between nodes. In this study, we provide the relationships and characteristics around authors and keywords in the JKSS(Journal of the Korean Statistical Society) of the Korean Statistical Society through the use of social network analysis and correspondence analysis.

We investigated the phylogenetic diversity of ammoniaoxidizing bacteria (AOB) in Yellow Sea continental shelf sediment by the cloning and sequencing of PCR-amplified amoA and 16S rRNA genes. Phylogenetic analysis of the amoA-related clones revealed that the diversity of AOB was extremely low at the study site. The majority (92.7%) of amoA clones obtained belonged to a single cluster, environmental amoA cluster-3, the taxonomic position of which was previously unknown. Phylogenetic analysis on AOB-specific 16S rRNA gene sequences also demonstrated a very low diversity. All of the cloned 16S rRNA gene sequences comprised a single phylotype that belonged to the members of uncultured Nitrosospira cluster-1, suggesting that AOB belonging to the uncultured Nitrosospira cluster-1 could carry amoA sequences of environmental amoA cluster-3.

This review focuses on the individual performance and productivity of researchers in the area of science and technology. The researchers in the paper are classified into individual inventors without organizational affiliation and researchers in the organization, which are distinguished by cosmopolitanic professionals and local institutionalists. The productivity of researchers is in general measured by different indicators or measurement scales such as: i) subjective evaluation of overall research performance, (ii) the number of published papers, reports and books, iii) the quality of research output (e.g. citation frequency), iv) originality of research ouput (e,g, patents), v) multiple measurement scales, etc. According to the literature based on empirical study, the productivity of individual reseachers is positively related to the degree of freedom, communication, diversity, dedication, and motivation and negatively related to the degree of similarity, and satisfaction. However, other factors such as creativity, age, supervisory behavior and group characteristics have shown irregular direction of correlation.

This study examines existing literature and uses case studies to identify the scope of fashion blogging and the evolving role of the personal style bloggers in the fashion business. Information on six popular personal style bloggers has been gathered to demonstrate the evolving business of these bloggers and their scope of operations that are relevant to fashion. The case of these six bloggers were drawn from popular media publications such as CNN, Wall Street Journal (WSJ), Time, Women's Wear Daily (WWD) and The New York Times. The case study of these six bloggers reveals that these personal style bloggers have used their reach and influence on the blog audience to procure and access business opportunities to grow their enterprise. The findings indicate that affiliation, partnership or collaboration with brands or established designers adds more value to a personal style bloggers resume. However, the findings also indicate that the popular fashion bloggers provide a new opportunity for marketing and promoting fashion brands and products to the younger generation.

This study analyzes the factors on the determinants of research productivity. In addition, this study uncovers the relationships between research productivity and various explanatory variables, and between explanatory variables. As for research productivity, 3 indices were used such as the number of papers, patents, and a combination of them. The data is the 3-year average from 2010-2012 by 1,383 researchers from 6 disciplines such as physics, chemistry, biology, mechanical engineering, electricity and electronics, and chemical engineering, reported to the National Research Foundation of Korea. Personal factors such as sex, age, academic rank and location of affiliation show the group difference for productivity. In addition, most resource factors such as the number of graduate students and research funds showed the same result with personal factors. As for the determinants, master and doctoral students and government funds are the most powerful factors for research productivity, but industry funds for patent and overall productivity.
