  • Oxidative changes of the Ramyon lipids were studied under three experimental storage conditions. Ramyon was 1) exposed to fluorescent light irradiation at $25^{\circ}C$, 2) incubated in the dark at $40^{\circ}C$ and 3) irradiated with ultra-violet light at $25^{\circ}C$. In the study, changes in acid value, peroxide value, carbonyl value, TBA number, fatty acid composition and iodine value were determined with the lipids extracted from the Ramyon samples in intervals for a period of 20 weeks. Acid value, peroxide value, and TBA number of the samples under fluorescent light irradiation and $40^{\circ}C$ incubation increased slightly during storage, while a sharp increase of those values were noticed with the samples of ultra-violet light irradiation. Especially, the TBA number of the Ramyon lipid under ultra-violet light irradiation markedly increased within 10 weeks and then decreased. With this change in TBA number, however, the bound form of malonaldehyde increased gradually. During the storage under $40^{\circ}C$ incubation, and ultra·violet irradiation for 10 weeks, the content of linoleic and linolenic acids decreased, while palmitic and stearic acids increased. However, only small changes were noticed in iodine value of the samples. On the other hand, oxidative rancid odor appeared at the end of 16 weeks storage under fluorescent light irradiation and $40^{\circ}C$ incubation, while it took only 4 weeks with the sample stored under ultra-violet irradiation.

  • To develop a convenient method for discriminating between violet flowered lines and white flowered lines in Chinese bellflower, RAPD analysis was carried out and SCAR markers were generated. Eighteen specific RAPD bands were obtained from 6 OPERON primer sets. Two out of eighteen RAPD bands were cloned into pGEM-T-Easy vectors and then subjected to the nucleotide sequence analysis. PgR1 and PgR2 DNA fragment, each specific for violet and white flowered lines, consist of 887 bp and 863 bp sequences, respectively. Two SCAR markers were developed from RAPD clones: SPgR1 (355 bp) from PgR1 and SPgR2 (493 bp) from PgR2. One (SPgR2) of these two markers was useful to differentiate between violet flowered lines and white flowered lines in Chinese bellflower.

  • The purpose of this study was to investigate the relationship between personality and color preference, thereby to suggest a personality profile on the basis of colors selected for children's preference. Materias used to determine the degree of color preference were 24 color papers which were developed and described in a previous research by Lee & Lee. The Instrument used ot determine children's personality was Burks' Behavior Rating Scales-Preschool and Kindergarten Edition. Subjects wee 70 3-, 4- and 5- year old children attending the Y Child Development research institute. Data were analyzed with SPSS using mainly F-test and Duncan's Multiple Range Test. Results showed that among 24 colors used, white, violet, sapphire, sky blue, blue, green yellow, pink, green, red, gold, purple, van dyke brown, blue, green, silver were found to be significantly related to persionality. Judging from this results, white and violet seemed to be most predictive colors to personality. Personality aspects significantly related to specific colors were discussed and a profile of personality based on color preference were developed.

  • Cinnamate group is well-known for the dimerization reaction by ultra-violet irradiation and cinnamate polymers are studied for photo-alignment materials. The cinnamate groups of flexible polymer are found to produce LC alignment parallel to polarization direction of ultra-violet light, which is contrary to the LC orientation on conventional cinnamate polymers. The un-reacted cinnamate groups in the flexible polymer are also found to participate in cycloadducts formation by additional thermal reaction that preserves the orientation of cycloadducts, leading to the enhancement of thermal stability of LC alignment.

  • This study was carried out to select effective fungicides against white and violet root rot caused by Rosellinia necatrix and Helicobasidium mompa with nine fungicides including thiophanate-methyl from 1993 to 1994. Through laboratory, greenhouse and field trials on inhibitory effect of mycelial growth and disease incidence against the two fungal pathogens, 5 fungicides have been selected finally. Thiopanate-methyl, benomyl, iminoctadine-triacetate and isoprothiolane were proven to have high control effect against R. necatrix. In addition to thiopanate-methyl and benomyl, tolclofos-methyl has been selected for effective control of H. mompa, since it showed prominent control effect in field trial than in laboratory or green house test.

  • ZnO crystals with different morphologies were synthesized through a thermal evaporation of Zn-Mn mixtures in air. The morphology was dependant on the Mn content in Zn-Mn mixture. The morphology was changed from rod to tetrapod shape with decreasing Mn content in Zn-Mn mixture. The result indicates that the concentration of Mn might be responsible for the different morphologies of ZnO crystals. XRD spectra showed that the ZnO crystals had a hexagonal wurtzite crystal strutures. For all the samples, room temperature cathodoluminescence spectra showed a ultra-violet emission at 380 nm and a green emission at around 500 nm. However, the intensity ratio of ultra-violet emission to green emission was significantly different with the Mn content in the source material.

  • The stabillities of taurine, niacinamide, and pyridoxine hydrochloride under exposure to ultra violet radiation in liquid preparations were studied. And sterilization effects for E. coli in both water and liquid preparations were also comparatively evaluated. The above mentioned organic compounds were stable under this experimental conditions and viable count of E. coli reveals that organic compounds dissolved in solution display protective action for microorganisms under UV-irradiation.
