  • Human factors engineering has been taught in the design fields and considered as a necessary course for design students, We, ergonomists working with a design department, analyzed the current status of ergonomics curricula in the Korean design colleges. Sixty one percent of schools with design departments were offering ergonomics courses and most courses were electives. Comparatively more ergonomic courses were offered in industrial design and digital media departments. Ergonomic and human factors knowledge might not properly be acquired with this current status of the design curricula and systematic solutions should be considered and prepared for the future Korean designers.

  • A new phenylpropanoid was isolated from the roots of Codonopsis ussuriensis (Rupr. et Maxim) Hemsley. It was coloress crystals, mp. 140-142.deg.C and was elucidated as 4-(3-ethoxy-1-propenyl)-2, 6-dimethoxyphenyl-$\beta$-D-glucopyranoside on basis of spectral data analysis.

  • The position of interglycosidic linkages of two acylated flavonol glucorhamnosides from Ginkgo biloba leaves was unambiguously determined as 1 $\longrightarrow$ 2 linkages rather than 1 $\longrightarrow$ 4 ones on the basis of spectroscopic and chemical evidence.

  • Novel anomeric branched carbocyclic nucleosides were synthesized from 1,3-dihydroxy acetone. 4'-Hydroxymethyl was installed by [3,3]-sigmatropic rearrangement reaction and 1'-methyl group was introduced by carbonyl addition of methylmagnesium bromide. The coupling of nucleosidic bases and desilylation afforded a series of novel nucleosides. The synthesized compounds $16{\~}19$ were evaluated for their antiviral activity against HIV-1, HSV-1, HSV-2, and EMCV. Compounds 16 and 19 exhibit toxicity non-related to any anti-HIV-1 activity.

  • We examined the inhibitory activities of various flavonoids, including the flavanones, flavones/isoflavones and flavonols, on collagenase from Clostridium histolyticum to establish their therapeutic potential against skin inflammation and photoaging. In general, the flavonols were stronger inhibitors than the flavones/isoflavones, and this indicated the importance of the C-3 hydroxyl substitution. Quercetin was the most active flavonoid among those tested, and it showed an $IC_{50}$ of 286 ${\mu}M$. These novel results suggest that certain flavonoids, particularly the flavonols, may prevent collagen breakdown by inhibiting collagenase in inflamed skin as well as photoaged skin.

  • A novel carboacyclic nucleoside analogue, 9-[2-bromo-4-hydroxy-3-hydroxymethyl-2-butenyl] adenine, and its derivatives were designed and synthesized as open-chain analogues of neplanocin A. The syntheses were accomplished via the coupling of adenine or pyrimidine bases to the key intermediate allylic bromide 7. The bromide 7 was prepared from epichlorohydrin in a seven step process in a 54% overall yield. The synthesized compounds were evaluated for their antiviral activity against the polio virus, HSV and HIV.

  • An anticoagulant, 4-hydroxy-3-[1, 2, 3, 4-tetrahydro-3-[4-(4-trifluoromethylbenzyloxy)phenyll-1 -naphthyl]coumarin (Flocoumafen) was synthesized in 8 steps starting from phenylacetyl shloride and anisole. The key step in the synthesis involves the reaction of 3-(4-methoxyphenyl)-1-teralol with 4-hydroxycoumarin to give 4-hydroxy-3 [1, 2, 3, 4-tetrahydro-3-[4-emthoxyphenyl]-1-naphthyl]coumarin.

  • The feature of resolution enhancement by derivative operation is linked to one of the multivariate analysis, which is multiple linear regression with two options, all possible and stepwise regression. Examined samples were synthetic mixtures of 5 vitamins, thiamine mononitrate, riboflavin phosphate, nicotinamide, pyridoxine hydrochloride and ascorbic acid. All components in mixture were quantified with reasonably good accuracy and precision. Whole data processing procedure was accomplished on-line by the development of three computer programs written in APPLESOFT BASIC language.
