방향족화합물을 생분해하는 미생물을 분리하여 생물학적 처리에 응용하기 위해 폐수 및 토양에서 150종의 균을 분리하였다. 그 중에서 COD 제거율과 방향족화합물의 이용능이 가장 우수한 HC107균을 선발하여 Pseudomonas sp.로 동정하였다. 활성슬러지 장치에서 Pseudomonas sp. HC107 배양액을 2ml/day씩 처리하면서 화학, 제약 및 도료공장의 폐수를 혼합하여 연속처리한 결과 처리수의 COD, BOD 및 phenol 제거율이 평균 92.5%, 95.53 및 93%.5로 나타났다.

The insecticidal activities of 30 aromatic plant extracts against four insect pests were examined by direct contact application. Against Nilaparvata lugens female adults, Myzus persicae female adults, and Plutella xylostella larvae, at 5,000 ppm, >90% mortality was achieved in the methanol extracts of the rhizomes from Cnidium officinale, Acorus gramineus, Acorus calamus var. angustatus and Curcuma Ionga, the whole plant from Agastache rugosa, the fruits from Illicium verum and Piper nigrum, and the flower bud from Eugenia caryophyllata as well as Cinnamomum camphora steam distillate. Against Spodoptera litura larvae, all test plant extracts were ineffective. The plants described merit further study as potential insect-control agents against insect pests.

We synthesized the two types of photoalignment material of high thermal resistance with hydroxyl aromatic polyimide, and studied the liquid crystal (LC) aligning capabilities on the photopolymer layers. Also, electro-optical (EO) performances for the twisted-nematic (TN)-liquid crystal display (LCD) photoaligned with linearly polarized UV exposure were investigated. A good LC alignment with UV exposure on the two types of photopolymer surface can be obtained. The Voltage-transmittance (V-T) curve in the photoaligned TN cell with UV exposure was different from two type. The response time of photoaligned TN cell was measured about 21 ms in two alkyl chain and about 15 ms in four alkyl chain.

The naphthenic base oil has been formulated to insulating and refrigerating oils. In the views of decreasing of the naphthenic crtide oil, new sources as its replacement have been needed. To solve this situation, the synthesis of naphthenic oil has been carried under hydrogenation reactions of alkyl aromatic compounds using various catalysts. The sturcture of reaction products has been investigated using spectroscopic methods such as NMR, UV, IR and HPLC. On the basis of the experimental results, it was convinced that unsaturated aromatic ring was saturated to saturated rings, and also optimum cond~tions established. Throughout this study, new resource as the replacement of conventional naphthenic oil has introduced.

Sixteen kinds of naturally occurring phenolic compounds including 5 stilbenes, 7 flavonoids and 4 anthraquinones were examined in the inhibitory activity against rat liver AADC(aromatic L-amino acid decarboxylase) in vitro, using 5-hydroxytryptophan as a substrate. Three hydroxystilbenes, resveratrol 1, rhapontigenin 3 and piceatanol 5, which were known to be monoamine oxidase A inhibitors, exhibited a significant inhibition against AADC($IC_{50}$=20, 8 and $5\;{\mu}M$, respectively). By the comparison of the activity of each phenolic compound, it was suggested that the 3',4'-dihydroxyphenyl group of stilbenes or flavones was the best pharmacophore for the AADC inhibitory activity.

A remediation technology consisting of biodegradation and a modified Fenton reaction was developed to degrade mixtures of polycyclic aromatic hydrocarbons (PAHs) at a former manufactured gas plant (MGP) site. The original Fenton reaction (i.e., $H_2O$$_2$ + Fe$^{2+}$) was modified to be biocompatible by using ferric ions and chelating agents such as catechol and gallic acid. The modified reaction was effective in degrading PAHs at near neutral pH and thus was compatible with biodegradation. By the combined treatment of the modified Fenton reaction and biodegradation, more than 98% of 2- or 3-ring hydrocarbons and between 70 and 85% of 4- or 5-ring compounds were degraded in the MGP soil, while maintaining its pH about 6.6.

we have investigated the effect of aromatic compounds and tree inception and growth in low density polyethylene, for AC voltage and Impulse voltage. 2kinds of aromatic compounds are selected. Each additive (m-cresol, aniline) was mixed in low density polyethylene. For AC voltage, 10wt% $\sim$ 15wt% m-cresol can be shown to be the effective inhibitor to tree initiation. But, For Impulse voltage, 10wt% $\sim$ 15wt% aniline is effective inhibitor to tree initiation.

Currently on the school education site, various multimedia contents are used to effectively deliver knowledge to the students and increase interest in class. The majority of the multimedia contents currently used in classes are composed of visual and auditory information. This paper intends to maximize actuality and immersion in the content by adding olfactory information to the existing visual and auditory data. Tangible contents were developed based on the details of aromatic plants learned in the fifth grade of elementary school. The shape and explanation of the aromatic plants are displayed with visual and auditory information, and an aroma spraying application is used to allow the students to smell the aromatic plants. After conducting the class using the developed contents, the students' satisfaction of the class, as well as their overall academic understanding, were investigated. Upon doing so, it was discovered that the students' academic understanding and satisfaction increased in comparison to classes comprised of only visual and auditory contents.

A new series of hyperbranched aromatic polyesters containing azoxybenzene mesogens and polymethylene spacers were prepared by polymerizing AB2 type monomers that have the isophthaloyl dicarboxylic acid terminal at one end and the p-oxyp henol terminal at the other end. The monomers contain a built-in azoxybenzene mesogen that is linked to the terminal groups through polymethylene spacers. The polyesters prepared were characterized by solution viscosity, differential scanning calorimetry, X-ray diffractometry and polarizing microscopy. All of the polyesters were found to be thermotropic (nematic). Their glass-transition temperatures and mesophase temperature ranges were very sensitive to the length of the two spacers existing in the repeating unit. The degree of branching of one of the polyesters was determined by the NMR spectroscopy and found to be 0.56.
