Quantitative trait loci (QTLs), which were related to the ability of callus induction and plant regeneration in seed culture of rice, were analyzed using a mapping population from a cross between the rice cultivars 'Samgang' (tongil type) and 'Nagdong' (japonica). A tongil type rice cultivar, 'Samgang' showed lower frequency (20%) of plant regeneration than that (35%) of japonica rice, 'Nagdong'. Transgressive segregations were observed for the ability of callus induction and plant regeneration from the seed-derived calli of 58 doubled haploid (DH) lines. The ability of plant regeneration of 58 doubled haploid lines showed a continuous distribution with comparatively wide range (10.0 to 66.7%) of variation. Composite interval mapping analysis was used to identify the QTLs controlling callus induction and plant regeneration ability. Four significant QTLs, qCWS6, qCWS8, qCWS9 and qCWS11, associated with callus weight per seed were detected on chromosomes 6, 8, 9, and 11 with LOD values of 3.30, 2.60, 2.70 and 2.43, explaining 36% of the total phenotypic variation. Three significant QTLs, qPR1, qPR6, and qPR11, for the ability of plant regeneration were located on chromosome 1, 6, and 11 at LOD score of 2.25, 2.15 and 2.55, accounting for 24 % of the total phenotypic variation. The present study should be useful for improving the efficiency of plant regeneration in tissue culture of indica rice by means of marker-assisted selection.

As more and more consumers shop online, websites of fashion brands have become effective means for business activities. The Colors of web sites are the most effective visual elements for e-tailers to communicate with consumers. The purpose of this study is to compare websites created for local and global markets by men's apparel brands. The empirical study focused on differences of color application between the local and global websites. Fourteen brands were chosen for the study. The main color, sub color, and accent color were extracted according to the screen component ratios for each website. The colors were analyzed by Munsell's 10 Hues and 12 tone classifications of Practical Color Coordinate System. The Results indicated that all websites were using White as the main color. The local website used pale tones while global websites used dark tones. There was also differences in the use of sub colors and tones. Red was most used as the accent color in both local and global websites.

Aeromonas hydrophila is a pathogen to fish as well as human. It is a food-borne disease, and causes severe mortality in fish, and sometimes severe septicemia in human. In this study, a rapid detection method using latex agglutination has been developed for A. hydrophila. Polyclonal antibodies were raised against membrane and whole cells of three isolates from rainbow trout. Among these, latex particles coated with antibodies raised against whole cells of isolate No. 2 showed the best sensitivity. With latex particles coated with this antibody, we could detect $5{\times}10^4$ CFU of A. hydrophila in 5 min. The cross-reactivity with bacteria constituting the normal intestinal microflora and other pathogens for rainbow trout was insignificant. This latex agglutination assay method produced positive reaction with all clinical isolates of A. hydrophila which were identified by species-specific PCR for 16S rRNA in A. hydrophila.

The purpose of this study is to explore how people's evaluation and preference on color palettes differ based on their cultural background. This study used the same color palettes developed by Youngsoon Park and Denise Guerin(1992). Fourteen representative adjectives are used to analyze the meaning evaluation and preference on the six color palletes. 425 undergraduate students are se-lected from Korea, Japan, U.S. and England and ques-tionnaire was used as survey instrument. The results show that there are significant differences among the four countries in the meaning evaluation and preferences on the color palettes and the characteristics of color palettes influence the differences among the countries. The differences among the countries decrease in case of color palettes composed of warm color with low or medium value difference and chroma difference, while the differences increase in case of color palette characterized by strong color contrast with high or medi-um value difference and chroma difference. The result of color meaning evaluation can be catego-rized into Western and Eastern culture. Korea and U.S., and Japan and U.S. showed significant differences in the most words and Korea and Japan showed similarities in the most words. Therefore it can be concluded that cul-tural backgrounds related to race, region and history in-fluence the color meaning evaluation and preference. Fur-ther study should explore the relationship between color and culture using more various color instruments such as color palettes in order to categorize the various aspects of culture.

Oilseed rape (Brassica napus L.) is an important crop due to its high oil content in the seed. Recently, the demand for the improvement of crop for biodisel energy source is increased as oil prices in the world has increased dramatically. Until now, oilseed rape breeding was carried out by cross-hybridization between different varieties and related germplasms. However, like as many other crops, the application of tissue culture and gene transformation systems has been introduced into oilseed rape breeding program including the development of transgenic canola plants. In this study, we reviewed a history of tissue culture and genetic transformation research in oilseed rape plants and indicated some important aspects for the production of transgenic oilseed rape plants.

Objectives: An increase in the number of caregivers is necessary to provide services to the elderly, but more importantly, it is qualitative management for them. The purpose of this study was to identify occupational stress, job satisfaction, and organizational commitment and to explore the impact of occupational stress on job satisfaction and organizational commitment among caregivers employed in health service centers for the elderly. Methods: This descriptive survey was a cross-sectional correlational design of 118 caregivers. The questionnaire included occupational stress, job satisfaction, and organizational commitment. Stepwise multiple regression was applied. Results: Job satisfaction and organization commitment of caregivers were found to be above the average. There was a high level of job stress due to lack of job autonomy, job demands, and inadequate compensation. It has been found that the inappropriate compensation, organization system, work culture, and lack of job autonomy affected job satisfaction of caregivers. The factors affecting organizational commitment were inadequate compensation, job insecurity, and work culture. Conclusions: Efforts should be made to assess and complement the appropriateness of compensation and work culture that are taken to relieve job stress to enhance the job satisfaction and organizational commitment of caregivers.
