About forty sea weeds were screened for their inhibitory effects against prolyl endopeptidase, tyrosinase and thrombus coagulation. Out of them, methanolic extract of Ecklonia cava, Sargassum patens, Sargassum hemiphyllum, Sargassum thunbergii, Sargassum singgildianum, Hizikia fusiformis, and Ishige okamurae inhibited more than 90% of prolyl endopeptidase activity at 40 ppm. Sargassum siliquastrum and Ecklonia cava exhibited 51% and 76% of inhibitory activity against tyrosinase at 40 ppm, respectively. In APTT assay system, Sargassum singgildianum, Pterocladia capilacea and Hizikia fusiformis delayed coagulation of thrombus about two times (210, 211, and 198% over control at ca 367 ppm, respectively) and in TT assay, Lomentaria catenata, Laurencia okamurae, and Hizikia fusiformis did most effectively (216,197, and 251% at ca 367 ppm, respectively).

Results from tests for what mixing rate of soil and sand is proper for the rammed earth and for how much additives are optimum are as under. 1) In the test to evaluate what mixing rate of soil and sand is desirable, peptizing property and surface sticking rate are found similar in its degree, but compression strength is found most stable when the ratio of soil and sand mixing shows 30:70 which indicates the best mixing rate of soil and sand. 2) In a test to add hydrated lime, compression strength, peptizing property, and surface sticking rate are found best when the mixing rate of soil and sand shows 23:7. 3) In a test to add sea weeds, the peptizing property goes down at 75% of sea weeds input a little bit more than at 100%, but compression strength shows best at 75% which is thought to be the best rate. 4) In a drop test, more soil powder mixed, the sticking strength gets better and more sands are contained, the sticking strength gets far worse to be scattered in powder type. 5) As concluding all results mentioned in the above item, the most desirable mixing rate of soil, sand, and hydrated lime is found to be 23:7:70 for the rammed earth where compression strength, peptizing property, and surface sticking rate are best.

Large scale of fish kills by red tides has been occurred every year in coastal water fisheries of Korea. To suppress red tide spreading out over the south coastal water of the Korean Peninsula large amount of loess has been applied every year because loess is known to be effective in removing red tide organisms. Effects of loess application in ecosystem of underwater near sea shore were investigated with some physical characteristics of loess. Loess used for the red tide reduction consisted of very fine particles, of which size was mostly less than 0.1 mm. Particles of loess blocked light penetration, which is essential for the underwater ecosystem. Loess also pushed pH down by the hydrolysis activities of aluminium and iron It was found that underwater ecosystems where loess was applied near sea shore were devastated. Sea plants such as sea weeds were gone leaving only their roots. Clams and snails were dead under the loess dust blanket. And fishes were not found at all where loess has been sprayed lot long time. It was found that even if loess has some capacity to reduce red tide temporarily, loess application should be slopped to protect underwater ecosystems.

This study was performed to investigate the influence of dietary fibers from the whole foods on the serum lipid level and bowel function in rats. The fiber sources of experimental diets were prepared by drying and milling of cereal(rice bran), vegetables(Korean cabbage, radish), fruit(apple), and sea weeds(laver, sea tangle). Each of fiber sources was mixed into the diet to make the 5% level of total dietary fiber. Male rats of Sprague-Dawley strain were blocked into 8 groups : FF, CC, CE, V1, V2, ER, S1, and S2. The animals were fed ad libitum each of experimental diets for 4 weeks. Serum triglyceride level was not significantly different among groups. The laver group showed the lowest level in the serum total cholesterol. The Korean cabbage group showed the highest level in the serum HDL cholesterol. The longest transit time was observed in the fiber free group and the shortest transit time was observed in the sea tangle group. Absorption rates of calcium were especially lower in the Korean cabbage and the sea tangle groups than the other groups. Magnesium and phosphorus absorption rates were influenced by SDF(Soluble Dietary Fiber) intake and TDF(Total Dietary Fiber) intake, respectively. Mucosa weight in the small intestine showed the tendency to increase by increasing of IDF (Insoluble Dietary Fiber) intake. especially the Korean cabbage group was the heaviest. The activity of maltase in the mucosa of small intestine was the lowest in the radish group.

The effects of sea tangle, sea mustard, hijiki, and glasswort were investigated based on the proximate composition, salinity, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics of reduced-salt (NaCl) meat batter and frankfurters. The moisture content, salinity, lightness of the meat batter and frankfurter, hardness, gumminess, and chewiness of the reduced-salt frankfurters with sea weeds were lower than the control without seaweed (p<0.05). The protein content, springiness, and cohesiveness of the reduced-salt frankfurters were not significantly different among the treatments (p>0.05). The moisture content, salinity, cooking loss, lightness, redness, hardness, gumminess, and chewiness of treatments with sea tangle and with sea mustard were lower than the control (p<0.05). Among the sensory traits, color was highest in the control (p<0.05). The flavor was also highest in the control. The treatments with sea tangle and with sea mustard samples had high tenderness, juiciness, and overall acceptability scores similar to the control (p<0.05). The results of this study show that the combination of low-salt and seaweed in the formulation successfully improved reduced-salt frankfurters, improving sensory characteristics to levels similar to the regular salt control (1.5%).

The purpose of this report is to present a list of Korean foods containing histamine, that is known to cause food allergy and chronic urticaria. For the measurement of histamine in foods, the application of spectrofluorimeter is used. Among the food groups, sea foods (mackerel, pacific saury, spanish mackerel, anchovy, hair, tail, tuna) contain most high amount of histamine, and the contents of see weeds (sea mustard, laverare) are also high. Milk and milk products (mozzarella cheese, yogurt) contain more histamine than animal meats. Plant foods like cereals, vegetables or fruits contain much less histamine than other food groups, except spinach. The contents of dried sesame, sesame oil, and mugicha, green tea, ginseng tea, mayonnaise, tomato ketchup are relatively high. This paper will be used as a fundamental guideline in planning dietary management of allergy and for the operational plans for the future nutrition education intervention. Because the foods rich in histamine may cause allergy-like syptoms, it may be reqoiled to label the foods containing histamine.

Large scale of loess has been applied on the south - sea shore of the Korean peninsula to treat red tides, due to many fishery's devastation by red tides every year. However, coastal ecosystem is ruined by the huge amount of loess applied every year. Almost all creatures, living under water such as sea weeds, clams, and fishes, where loess was applied, are disappearing. In this paper, alternative methods of the loess application are investigated. The amount of loess could be reduced by the alternative methods, Especially, loess mixed with calcium oxide has excellent effects to reduce Cochlodinium polykrikoides numbers. It was found that when loess is used with calcium oxide(CaO), removal efficiency of red tides is highly increased. Moreover, the amount of loess could be reduced dramatically.
