Journal of Sericultural and Entomological Science, volume 47, issue 1, 2005, Pages 1~4
As mulerry fruit has been increasingly evaluated as desirable for use in fresh and processed food and drink such as jam, juice and mulberry wine, opportunities for using the mulberry plant as a fruit sources have grown. With the demand for the mulberry fruits, mulberry fields for the production of mulberry fruits are increasing. To establish the mulberry cultivation methods for mulberry fruits production, effects of spacing and branch length on the productivity of mulberry fruits and growth of mulberry were studied.

When inoculating with B. bassiana 101A for the mass production of B. corpus, the infection ratio was high with regardless of the treating time with highly-humidity if the concentration of spore was 1.0
spores/m/, but that was low if the concentration was 1.0
spores/m/. In the study of the activities according to the coserving temperature or days of the B. bassiana spawn, the infection ratio of 90% was maintained for 12 days in the temperature of
. However, the infection ratio was rapidly dropped to the below of 5% after conserved for 48 hours in the temperature of
. Besides, the activities of the original isolate had no difference after conserved for 12 months in the temperature of
, so that the infection ratio 90% could be mintatined. In the measure of liver-protecting activities of B. bassiana 101A, the recovering effect was 43.5% and 65.7% respectively in the poisonous treatment induced with galactosamine, compared with liver-protecting activities of Silymarin and DDB in the
fraction. In the poisonous treatment induced with
the recovering effect was 100% and 69.3% respectively, compared with liver-protecting activities of Silymarin and DDB in the EtOAc fraction.

To develop technique for the production of P. tenuipes stromata on a large scale, the infection of P. tenuipes and the growth of stroma were investigated by silkworm (Bombyx mori) variety. Also, studied about biological activites of fruiting body formed on silkworm. Infection rate of the 5th instar larvae of the silkworm with P. tenuipes was the highest in Yangwonjam, followed by Hachojam, Baegokjam and Chilbojam in that order. Also, as the inoculation times was increased, infection rate tended to be raised. The rate of fruiting body formation of the silkworm pupae infected with P. tenuipes was the highest in Baegokjam, followed by Yangwonjam and Chilbojam in the order. But, actually the fruiting body formation of the 5th instar larvae of the silkworm tested was good in Chilbojam, followed by Yangwonjam and Baegokjam in that order in 3 times spraying inoculation. The fruiting bodies of Yangwonjam and Chilbojam infected with P. tenuipes had high amount of Mannitol, but Baegokjam and Hachojam had high concentration of Glucose on a dry weight basis. The mean content of total amino acid in the fruiting bodies of P. tenuipes was 1.03
. The distribution rate of amino acid components decreased in the order of Arginine (12.2%)>Glycine (10.5%)> Proline (9.6)>Tyrosine (8.9%)>Serine>Leucine>Threonine. The most abundant amino acid in the fruiting bodies of the Baegokjam, Chilbojam and Hachojam infected with P. tenuipes was arginine, while Yangwonjam was Glycine. The most abundant fatty acid in P.tenuipes was Oleic acid on a dry weight basis. The unsaturated fatty acids such as Oleic acid, Linoleic acid and Linolenic acid accounted for more than 78% of the total fatty acids.

Morphological characteristics of Cordyceps species and its allies collected in Korea were clarified. Through the survey conducted from June 1999 to October 2002 in 19 mountains in Korea, 667 samples of entomogenous fungi were collected. Cordyceps and its allies of 17 species of 5 genera were identified as Cordyceps gracilioides, C. japonica, C. longissima, C. martialis, C. militaris, C. myrmecophila, C. nutans, C. pruinosa, C. sphecocephala, C. tricentri, Hirsutella nutans, Paecilomyces cicadae, P. farinosus, P. tenuipes, Paecilomyces sp., Shimizuomyces paradoxa, Tilachlidiopsis nigra. The fungi with insect hosts have been collected mainly in the place of shade or mosses near brooks and streams that had high humidity. Overall the frequenct of fungal infection in natural ecosystem was relatively low as few as 10 collections per each species. However, many species were found in terms of the few number of colleciton sites with seasonal limitations. Occurrence of the fungi in Jeju island remote from inland of the Korean peninsula were diverse in their species due to the varied weather of vertical distribution following the altitude. Three most common species were C. nutans, P. tenuipes and C. militaris, mainly found early in August when the relative humidity and temperature were high, of which C. nutans occupied the highest frequency consisting of 65% in total collections. Neither variation in ascomata arrangement in stromata nor developement of secondary spores was recognizable, while the number, shape and colour of stromata varied with insect hosts and weather conditions.

This study had done to find an easily-dyeing method for novices because the dyeing method of traditional indigo has not been general to the public so that only an expert could dye the fibers. The results are as the following. When the powders after burning the shell of cockle (tegillarca granosa) were added. pH of the solution was 12.35 The k/s value of 2.49 was the highest in the dye after dipping in the solution of indigo for 1-2 days and the k/s value was 3.10 when adding 20 g/l of the starch (55% corn-starchy products in Korean market) into the solution of indigo. In addtion, the k/s value was the highest when fermenting temperature was
and when the powders after burning the cockle shell were 4 g/l. There were no differences between water and lye of rice straw which had used for the ferment of indigo. The components of two dye which has traditionally made of the cockle shell and which has made of calcium hydroxide were all the same.

Kim, Yung-Dae ; Chung, In-Mo ; Lee, Kwang-Gill ;
Journal of Sericultural and Entomological Science, volume 47, issue 1, 2005, Pages 36~40
This studies were carried out to develop the new silk degumming method by elelectrolyzed alkaline water on the silk degumming process. Using to this method, it could be collect pure sericin from the degumming water, because the degumming water by elelectrolyzed alkaline water was not contaminated by chemicals including soap. The range of elelectrolyzed alkaline water was pH 11.5 to 11.7 and maintained the first value for 8 days under the cool and closed conditions. The degumming ratio of silk was higher in elelectrolyzed alkaline water(pH 11.5~11.7)than that of soap and alkaline bath. When the pH value of elelectrolyzed alkaline water was adjusted at pH 11.0, the degumming ratio of silk was similar to that of soap and alkaline degumming. After degumming the pH value of degumming water decreased largely in the elelectrolyzed alkaline water compared to that of soap and alkaline bath. The tenacity and elongation of degummed silk by elelectrolyzed alkaline water was almost same those of soap and alkaline degumming for 90 min.

Kayagum is a traditional musical instrument in Korea. Kayagum strings are usually made of raw silk. It needs good vibration and durability. This study was carried out to increase durability of the strings by chemical treatment and manufacture of silk/polyester and silk/wild silk compound yarn. In this study, we used MKW-810(water solube acrylic adhesive)and polyvinyl alcohol as a adhesive. Before the twisting, the raw silk wet on the string manufacture process. The adhesive reagent were added in this process. And compound yarn were prepated by domestic silk, polyester and wild silk(antheraea pernyi) for make of Kayagum strings, respectively. The result are as follows. 1. Tenacity and elongation of the strings are almost same between none and chemical treatment. However number of extension cycling to breaks of the strings was largely increased by chemical treatment. Number of extension cycling to breaks of the strings is very important and useful item to check durability of the strings. The stiffness of the strings were almost same between none and adhesive treatment 2. Tenacity of the silk/polyester strings is largely decreased by increasing of polyester portion, but elongation of the silk/polyester strings increased. However tenacity of the silk/polyester(mono filament) strings are higher than that of silk strings. 3. Tenacity of the domestic silk/wild silk strings is largely decreased by increasing of wild silk portion, but elongation of the domestic silk/wild silk strings is almost same among silk and domestic silk/wild silk strings.
