The 185 ribosomal RNA gene (185 rDNA) of the marine alga Porphyra sp. 723 (Bangiales, Rhodophyta) was amplified using the polymerase chain reaction and its sequence was analysed. The Porphyra species was a summer strain collected on rocks in upper intertidal zone at Ikidae, Pusan on 23rd July 1999. The fronds were $1{\~}5 cm$ long, monostromatic, and orbicular or ovate shaped, They had spinulate processes at margin of the frond, Comparison of this 185 rDNA sequence with the other Forphyra species indicates that Porphyra sp. 723 has the same 185 rDNA sequence derived from Porphyra suborbiculata (NCBI access number; AB 013180) except one base pair substitution in 2327 base pairs.

In our continuing study on the antioxidant activity of Polysiphonia stricta, its crude extract was fractionated into n-hexane, 85% aqueous methanol (85% aq.MeOH), n-butanol (n-BuOH), and water fractions according to solvent polarity. The solvent fractions were evaluated for their potential to inhibit lipid peroxidation and reactive oxygen species (ROS) production in HT 1080 cells. The n-BuOH fraction most strongly inhibited both lipid peroxidation and ROS production in HT 1080 cells. The n-BuOH fraction was further separated by repeated silica gel column chromatography and RP-HPLC to give methyl aconitates (2 and 3). The chemical structure of isolated compounds was determinated by NMR spectral analysis.

Objectives: Hormone replacement therapy may relieve many symptoms of menopause; however, hormone replacement therapy may increase the risk of breast cancer, stroke, and dementia. This case study describes the effect of Hoechunboeum-tang on the menopausal disorder of hot flashes, which has been well documented as a cause of distress to patients undergoing menopause. Methods and Results: Two female patients suffering from severe hot flashes related to menopausal disorders were administered the herbal medicine, Hoechunboeum-tang. Measurements included hot flash frequency over a 24 hour period, hot flash severity (visual analogue scale), and hot flash-related daily interference and were recorded during the last week before herbal medicine and again after 7 and 15 days of herbal treatment. The patients were asked about their hot flash symptoms 6 months later and both reported that the symptoms had been successfully reduced after herbal treatment and were still reduced after 6 months. Conclusions: Hoechunboeum-tang could have a beneficial effect on menopausal disorder with hot flashes.

Biocomposites were fabricated with biodegradable polymers and natural fibers. Biocomposites have benefits of low cost, low density, and biodegradability over inorganic fiber composite, and give comparable strength properties. Hydrophobic polymer used for sizing in paper industry, AKD (Akenyl Keten Dimer), was applied to natural fibers, red algae fibers (RAF) in this study, to make fiber surfaces more compatible to hydrophobic nature of matrix polymers. Composites with RAF, kenaf, glass fibers, and carbon fibers have been fabricated by a compression molding method and their thermo-mechanical properties have been studied. Also, the thermal dimensional stability test was done from at 30 to $100^{\circ}C$. The storage moduli and the thermo-mechanical stabilities of polypropylene and poly lactic acid based biocomposites were improved by reinforcing with the RAF and much more with AKD treated fibers. Dimensional stability of biocomposite was also markedly improved by AKD pretrement on RAF.

전도성 고분자에 곁가지로 chromophore를 결합시켜 만든 다양한 전기 변색 물질과 그 특성을 소개하였다. 전도성 고분자로는 Polypyrrole, Polythiophene, Poly(3,4-ethylenedioxythiophene), Poly(cyclopen-tadithiophene), 및 poly (1,4-bis [2- (3,4-ethylenedioxy)thienyl] benzene)를 사용하고, chromophore로는 viologen과 perylenetetracarboxylic diimide를 사용한 경우에 대하여 설명하였다. 전도성 고분자와 thromophore의 변색 파장 범위가 다른 경우에는 변색의 다양성을 성취할 수 있었으며, 변색 파장 범위가 비슷한 경우에는 색대비를 높일 수 있다. 최대 색대비를 나타내는 필름의 두께를 쉽게 예측할 수 있는 방법도 설명하였다.

일상 식생활에서 널리 섭취하고 있는 식용 및 미식용인 16종의 해조류를 사용하여 니트로사민의 직접적인 생성인자인 아질산염 소거작용에 관하여 검토하였다. 그 결과, 갈조류의 경우가 녹조류 및 홍조류에 비해 우수한 분해효과를 나타내었으며 갈조류 중에서도 다시마과의 감태, 곰피, 구멍쇠 미역이 뛰어난 아질산염 분해효과를 나타내었다. 또한 각 시료 모두 pH의존성이 크게 나타나 pH 4.2 및 6.0에서 보다 pH 1.2에서 아질산염 분해효과가 뛰어났으며 아질산염 분해효과가 우수할수록 환원력이 높아 아질산염 분해능과 환원력은 밀접한 관련성을 나타내었다.

Galactose, an isomer of glucose with an opposite hydroxyl group at the 4-carbon, is a major fermentable sugar in various promising feedstock for hydrogen production including red algal biomass. In this study, hydrogen production characteristics of galactose-glucose mixture were investigated using batch fermentation experiments with heat-treated digester sludge as inoclua. Galactose showed a hydogen yield compatible with glucose. However, more complicated metabolic steps for galactose utilization caused a slower hydrogen production rate. The existence of glucose aggravated the hydrogen production rate, which would result from the regulation of galactose-utilizing enzymes by glucose. Hydrogen produciton rate at galactose to glucose ratio of 8:2 or 6:4 was 67% of the production rate for galactose and 33% for glucose, which could need approximately 1.5 and 3 times longer hydraulic retention time than galacgtose only condition and glucose only condition, respectively, in continuous fermentation. Hydrogen production rate, Hydrogen yield, and organic acid production at galactose to glucose ratio of 8:2 or 6:4 were 0.14 mL H2/mL/hr, 0.78 mol $H_2$/mol sugar, and 11.89 g COD/L, respectively. Galactose-rich biomass could be usable for hydogen fermenation, however, the fermentation time should be allowed enough.

Objectives: The purpose of this study is to analyze the correlation between the pulse energy and hot flush in women who complain of climacteric syndrome. Methods: We analyzed the values of pulse energy on 78 of perimenopausal and postmenopausal women. The symptoms of patients were assessed by Kupperman’s index (KI) and Menopause Rating Scale (MRS). Statistical analysis was performed by Spearman correlation coefficient and student T-test, using SPSS 18.0 for window program. Results: The results were as follows. 1. There were no statistically significant relation between pulse energy of left Cheok subtracted from left Chon and KI, MRS hot flush score. 2. When divided depending on MRS hot flush score, There were no statistically significant differences on pulse energy. Conclusions: The results suggest that there is no correlation between hot flush score and pulse energy.
