Biosurfactant-producing bacteria, showing strong crude oil degrading activity, were isolated from the caverns of National Oil Storage Basement. From the results of biochemical and molecular biological tests, the isolate was identified as Pseudomonas fluorescens PD101. It grows well on liquid media at temperature range from $20^{\circ}C\;to\;37^{\circ}C,$ but it does not produce biosurfactant when grown at $37^{\circ}C$ or at higher temperature. The biosurfactant was stable at broad pH range from 5 to 11 and under heat treatment condition of $100^{\circ}C$ for 30 min. The biosurfactant produced dark blue halo around the colony when grown on SW agar plates, which could confirm the biosurfactant as one of rhamnolipid group. The 700 bp of PCR product could be amplified from DNA of P. flurorescens PD101 by using PCR primers designed from rh1A gene of P. aeruginosa, and it showed $99\%$ of sequence homology with rh1A gene of P. aeruginosa encoding rhamnosyltransferase 1.

High oxygen pressure has been applied for a floating zone (FZ) crystal grower in order to grow high quality $TiO_2$(rutile) single crystals suitable for optical application. The $TiO_2$ crystals, grown under 0.3, 0.4, 0.5, and 0.8MPa oxygen pressure respectively, are all transparent and dark blue. The degree of the presence of sub-grain boundary in the crystal differs from the applied oxygen pressure. In particular, $TiO_2$ single crystals grown under0.5 MPa showed sub-grain boundary-free and estimated good for optical devices.

In order to investigate the changes of rice qualities during 4 years storage of paddy in warehouse of normal temperature condition. As storage period go by, head ratio was deduced and broken rice was increased according as a change of temperature during the long term storage. A color of rice was became more dark gray than that of entering time as L value was decreased from 64.07 to 61.62 a 4 years late. As a results of studies on the cooking quality of milled rice, water uptake ratio and expanded volume were increased in proporation to storage period, wherease total solids and iodine blue value were decreased. In the characteristic of texture of cooked rice, viscosity/hardness ratio(-H/H) had a decreasing tendency, while adhesiveness and cohesiveness increased with increased storage time. The qualities of cooked milled rice studied were sensory attributies of odor, taste, stickiness and appearance which were evaluvated by multiple comparsion method. The sensory results showed that all of descriptions were deterirated with a increased storage period. The taste and stickiness were changed from good score to bad score a 2 years later.

The purpose of this study is to investigate the effect of eyeshadow color (brown, purple, and blue), lipstick color (red, red purple, and yellow red), and lipstick tone (vivid, light, dull, and dark) on impression formation. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 36 color pictures manipulated with the combination of eyeshadow color, lipstick color, and lipstick tone using computer simulation. The subjects were 216 female undergraduates living in Jinju city. Impression factor of the stimulus was composed of 4 different components, attractiveness and gracefulness, visibility, cuteness, and softness, of which the first two were important. Eyeshadow color, lipstick color, and lipstick tone independently influenced the attractiveness and gracefulness and visibility. In the cuteness and softness, eyeshadow color and lipstick tone showed independent effect. In the interaction effect, the combination of lipstick color and lipstick tone showed significant effect on the attractiveness and gracefulness, visibility, and cuteness. Finally, it was found that the combination of eveshadow color and tpstick tone showed significant difference in the softness.

The purpose of this research was to compare the harmony of tone on tone coloration according to transformation of color area-ratio in shirt and necktie. The respondents were asked to evaluate 48 stimuli of the shirt and necktie with the coloration of the shirt/necktie, the necktie/shirt was separately compounded to be 4 tones such as vivid, light, dull, dark. The subjects were 288 female undergraduate students. The data was analyzed by using SPSS program. Analysis methods were ANOVA, LSD test and t-test. The results of each can be summerized as follows. As to the red, combination of v-lt made a difference in the harmony of coloration according to the transformation of color area-ratio. As to the blue, combination of v-lt, v-dk, lt-d made a difference in the harmony of coloration according to the transformation of color area-ratio. As to the purple, v-lt, v-d was evaluated as harmonized coloration regardless of area-ratio by both male and female students. As to the green, v-lt, lt-d was evaluated as harmonized coloration regardless of area-ratio by both male and female students.

We propose the use of visible scintillation light for monitoring the X-ray CT in the gantry of a diagnostic CT for its performance test and maintenance works. We placed a disk of bare plastic scintillator disk in the gantry opening area of a helical X-ray CT. When we operated the CT, we could observe the emission of blue scintillation light from the scintillator in a dark room. Visible light was identified under all scanning conditions of diagnostic uses. As a result, we observed the direction and the spread of the incident X-ray in the scintillator. We also observed the change of the part of the scintillator where visible light was generated, and the move that took place associating with the rotation of the X-ray tube during one CT scan. On the basis of the observation, we examined the usefulness of the visible scintillation light as a convenient performance-evaluating tool as well as a maintenance tool of the CT.

This study is on the application of ceramic body and art glaze by using coal ash according to each wt%. Body color was turned red and dark as increasing coal ash contents in the body and art glaze because of the effect of noncombustible carbon in $Fe_2O_3$ and coal ash. Not only pore and black core were generated but also absorptance and shrinkage were increased as increasing coal ash contents. The glaze of coal ash 20 wt% showed blue absorption band, turned red band as increasing coal ash contents, $Al_2O_3\;to\;SiO_2$ ratio got lower and became mat because glaze is estranged from $Al_2O_3\;to\;SiO_2$ mol ratio 1:10 of transparent glaze as increasing coal ash contents. Glaze showed unstable dissolving condition in the more coal ash contents.
