  • It is useful to find something valuable for researching through literature based discovery. Swanson's ABC model, known as literature based discovery, suggests the relationship between entities undiscovered yet. This study tries to find the valid relationship between entities by referring to citation which connects articles on similar topic. We collect citation from references in articles, and extract important concepts in titles and abstracts through text mining techniques. We reproduce the relationship between fish oil and Raynaud's disease, which is known as one of Swanson's works, and compare the results with entities identified from traditional approach.

  • In the present field study, the number of woody flora of Mt. Songni were summarized as 44 families, 89 generas, 140 species, 10 varities and 2 forms. Also, the flora among inland areas such as Mt. Paektu, Mt. Sorak, Mt. Songni, and Mt. Chiri, and insular areas, such as Oyoujong Island. Tokjok Archipelago, Kok-unsan Archipelago and Cheju Island, were compared, respectively, in order to interpret the characteristics of distribution patterns of the flora of this area. The flora of Mt. Songni were characterized as similar to the flora of Mt. Sorak, and also with that of Mt. Chiri. It was interpreted both the northern types of plants such as Aceraceae, Araliaceae, Fagaceae, Tiliaceae and Ulmaceae and the southern types of plants such as Celastraceae, Convolvulaceae, Euphorbiaceae, Rhamnaceae, Solanaceae, Crassulaceae and Urticaceae were fluxed considerably into this region.

  • This study was designed to determine changes of serum glucose and lipid levels in noninsulin dependent diabetes mellitus patients during different doses of docosahexaenoic acid (DHA)-rich fish oil supplementation. All patients had a fasting blood glucose of less than 180mg/dl, a LDL-cholesterol of less than 160mg/dl, and a triglyceride of more than 160mg/dl. None had clinical evidence of renal, hepatic or coronary vascular disease. Sixteen patients served as control. Seven patients ingested 2.00g of fish oil(low dose group), consisting of 0.30g eicosapentaenoic acid(EPA) and 0.55g DHA. The group of modest dose(n=9) was provided 3.91g of fish oil, consisting 0.59g EPA and 1.08g DHA. After 4 weeks, serum triglyceride concentration showed a mild but nonsignificant elevation in control group, a 9% decrease(194 to 177mg/dl) in the group of low dose of fish oil and a 28% decrease(206 to 161mg/dl) in the group of modest dose. The level of high density lipoprotein(HDL), HDL2, HDL3 and total cholesterol in all groups were not changed. There was a mild increase in malondialdehyde and low density lipoprotein(LDL)-cholesterol concentration and decrease in $\alpha$-tocopherol concentration. However, these changes were not significant.

  • Matrix metalloproteinases(MMPs) are a group of zinc enzymes responsible for degradation of the matrix components such as collagen and proteoglycans in normal embryogenesis and remodeling and in many disease processes such as arthritis, cancer, periodontitis, and osteprocess. Genetically distince MMPs have been characterized and their genes have been cloned thus far from a variaty of species but not from fishes. In this stydy, a mmp cDNA was cloned by using RT-PCR(reverse transcriptase dependent polymerase chain reaction) from Scylliorhinus toraxzame(shark), agroup of cartilaginous fish, abundant in the coast of Pusan, Korea. It has 74% base homologue with membrane type matrix matalloproteinase-3 genes(mt3-mmps) from human, rat and chick, and also shows more than 90% residue homologue with them. In addition, it has cysteine switch domain, zinc binding domain(HExGH motif), propeptide cleavage site, and RRKR motif, which are present in MMPs. This result indicates that cDNA fragment cloned here may be mt3-mmp or its analogous gejne cDNA fragment of Scylliorhinus torzame.

  • Sardine oil was vacuum-steam deodorized at $170^{\circ}C$ with acid (acetic and citric acid) and ethanol solution as steam sources. Glycerol was added to fish oil to remove volatile odorous constituents. The storage stability of deodorized fish oil was determined by totox value, secondary parameter obtained from peroxide and anisidine values. Both deodorization with acetic acid solution and addition of glycerol to the oil resulted in improved storage stability. The totox values of fish oil deodorized with water, glycerol+water and glycerol+acetic acid solution were 936, 611, and 443, respectively after 10 days at $30^{\circ}C$. The result showed that acetic acid seemed to destroy the odorous constituents and glycerol accelerated the removal of odorous constituents, such as amines in fish oil.

  • This study was carried out in order to investigate the browning reactions of fish oil-amino acid model system and the properties of browning products. The lysine was added to the hair tail fish and mackerel oil, and incubated at $40^{\circ}C$ for 178 hours. Browning was rapidly developed with the begining of decline in PoV and CoV and a remarkable decrease in such polyunsaturated fatty acids as $C_{20:5},\;C_{22:5},\;C_{22:6}$ compared with the other fatty acids, was resulted. And among the polyenoic acids the role of $C_{22:6}$ was considered to come first as appeared in the test with authentic samples. In the water soluble fraction of the browning products obtained from the fish meat or the lysine added fish oil, some antioxidation activity was detected. But in the liposoluble fraction which covers most of the browning reactions in the fish meat, little antioxidation activity was detected. And all of the browning products provided in this experiment shelved very low reducing activity.

  • Alginates are used to encapsulate various materials, including food, cosmetics, and pharmaceuticals. This study examined the properties and oxidation stability of fish oil capsules manufactured with calcium alginate gels. The fish oil capsules were manufactured by dropping sodium alginate solution and fish oil into a calcium chloride solution through nozzles. The membrane thickness, sphericity, rupture strength and deformation depth of the fish oil capsules were determined. The peroxide value of the fish oil was assayed to determine the oxidation stability of the capsules. The capsules measured approximately 3 mm with a membrane thickness of 90 μm independent of the amount of fish oil added. As the amount of fish oil encapsulated increased, the sphericity, rupture strength and deformation depth of the capsules decreased. The encapsulation efficiency increased until the amount of fish oil was 30%. The oxidation stability of fish oil in capsules was dependent on the type of nozzle, e.g., the oxidation stability of fish oil in capsules made using a double nozzle was greater than with a single nozzle. These results should lead to industrial application of fish oils including eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, as nutraceuticals.

  • We built subway stops in order to meet demand. To do so, a standardized method is used to predict the demand. However, in some subway stops there are only few people moving around sparsely, but in some other stops there are too many people crammed in a crowd. The gap between forecasting and actual uses varies from 10% to more than 1,000%. This study is aimed to find out where this discrepancy between predicted vs. actual demand for urban rail transit comes from. Specifically, 40 subway stops in Seoul Metropolitan Area, which were opened last 10 years, are examined. This study suggests that, for better forecasting, we need to consider stops' locational characteristics as well as weekday commute-oriented exogenous factors. Locational characteristics includes; whether a stops is a terminal and/or weekend tourism node. There seems no "one size fits all" solution for transit demand forecasting; locational characteristics need to be reflected.

  • This study was conducted to investigate the influence of dietary mugwort (0, 1, 2, 4%) and sardline oil(1%) on weight gain, pH, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), and meat color in meat-type chickens. Birds were randomly assigned to the four dietary treatments: control (commercial feed), control plus 1% mugwort and sardine oil (T1), 2% mugwort and 1% sardine oil(T2), or 4% mugwort and 1% sardine oil (T3). Birds were sacrificed and meat samples were taken and stored for either 0, 3, 7 or 10 days at $4^{\circ}C$. Weight gain in T3 was lowest than other treatment groups (P<0.05). pH of dietary mugwort and sardine oil treatments increased significantly compared to that of control during storage periods (P<0.05). VBN and TBARS of all treatment groups were significantly increased as storage period extended (P<0.05). Meat color $(L^*,\;b^*)$ significantly increased during storage periods. $L^*\;and\;b^*$ values were higher in treatment groups than in control (P<0.05). These results indicate that the mugwort and fish oil may improve quality and self-life of meat-type chickens during storage.

  • In this paper, combustion characteristics and engine performance varying with blending rate of fish oil using five test fuels, e.g.pure diesel oil and four types of sardine-oil-blended diesel oils, their blending rates by weight being 20%, 40%, 60% and 80% respectively, and operating condition of engine, were investigated experimentally both in the constant volume combustion bomb and in the engine. The results are summarized as follows: 1) In the bomb, the influence of temperature on ignition delay of sardine-oil-blended diesel oils was larger than that of pure diesel oil, and it tended to increase as the blending rate of fish oil increase sardine-oil-blended diesel oils. As far as the influence of pressure on ignition delay concerns, there was no significant difference with all the test fuels. 2) In the engine, the ignition delay of fish-oil- blended diesel oils was longer than that of pure diesel oil, and it tended to increase as the blending rate increases. In the bomb, the ignition delay in high temperature showed no significant difference between with pure diesel oil and with fish-oil-blended diesel oils, and it was especially short with 60% fish-oil-blended diesel oil. In low temperature, however, the delay became longer as the blending rate increase. 3) The combustion duration was shorter with fish-oil-blended diesel oils than with pure diesel oil and it became a little shorter as the blending rate increases. 4) The rate of fuel consumption showed no significant difference between with fish-oil-blended diesel oils and with prue diesel oil, although calorific value of fish oil was lower than that of diesel oil. 5) Smoke density in exhaust gas was lower with fish-oil-blended diesel oils than with pure diesel oil and the higher the blending rate was, the lower the smoke density became.
