  • This study was conducted to determine the influence of culture conditions such as temperature, time, water content, koji-thickness, and agitation on the production of protease by Rhizopus sp. ZB9, isolated from Korean Nuruk, during the preparation of rice koji, which is used in brewing the Korean rice wines, Takju and Yakju. Rice koji was made under different culture conditions, and the proteolytic activity of each koji was tested. The temperature range suitable for the production of protease was $28~32^{\circ}C$. Based on the protease and color, 60 hours of cultivation at $28^{\circ}C$ was shown to produce optimum results. The production of protease increased in proportion to the increase in water content of steamed rice from 25% to 35%. An increase in koji-thickness induced no adverse effects on the production of protease, and agitation during cultivation showed beneficial effects.

  • The purpose of this study was to suggest the data of base for automated underwear manufacture by analyzing the technology of the automated underwear manufacturing facilities in the area of Jeonbuk with a focus on Jeonju and Iksan. The case study samples were 6 underwear firms. The results were as follows : 1. Automated underwear manufacturing systems in the area of JeonBuk introduced over the entire period between 1990 and 1997. Most of Their production type was multi-kind and small-quantity production. 2. They were using Gerber, Assyst, Lectra, Microdynamics and Investronica systems as the CAD/CAM system, of which the Gerber system was mostly used by them. 3. In the stage of production planning and in the stage of preparation for production, most of them realized automation, but in the stage of main production, every firm did not realize automation. In most cases, they used both the stage of mechanization and the stage of unit process automation.

  • This study was conducted in order to figure out the energy consumption pattern in rice production system of Korea, with literature investigation focused on energy requirement in rice production system in worldwide. The investigation reveals that 24,994 MJ/ha was needed to produce 4,500kg of rice production or 5.55 MJ/kg was consumed. The major enegry consumptions are resulted from the application of nitrogen fertilizer, fuel for farm machinery, and farm machinery embodied energy, which showed somewhat different energy consumption pattern than that of the developed country, like, U.S.A. Based on the machinery chosen in this investigation, it was found that 32.7% of the fuel energy, 2,431.8MJ, was consumed in drying operation, 32.2%, 2.402MJ, in tillage and land preparation. 25.8%, 1.923.6MJ in harvest. A linear relationship was found in pre harvest energy input and output of rice production.

  • Nuclear transplantation technique is known as the most potential and efficient method for producing a large number of genetically identical animals from a single embryo. The technical development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection and micromanipulation of recipient eggs or embryos as capacious recipient cytoplasm, the adequate and benefitlal preparation of multiple totipotent embryonic cells as donor nuclei, and also the fusion technique are very critical. Recent studies approaching to these critical points are introduced and discussed. Up to date, the overall efficiency of production of cloned embryos and offspring in livestock is estimated to be low. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.

  • This research developed satellite account for household production to measure the whole size of production in Korea. The standardized satellite account was designed on the basis of Ironmonger's IO table. Results of this research were summarized as follows. First, the economic values of male and female labor invested for household production was 1,560,000 and 5,380,000 Won, respectively. Female input was greater than male by 3.5 times. Second, the expenditure for durable goods for household production was on average 470,000 Won per year. Among the total expenditure, 36% was spent for household management activities, 25% for food preparation and 25% for cleaning and laundry. Results of examining the expenditure for durable goods in total production activities showed that more than half was spent for household production; 54% for household production, 39% for leisure, 4% for sleeping, and 3% for individual use. Third, among expenditure of consumption for intermediate foods for household production, expenditure for food was the greatest to be followed by expenditures for child care, other houseworks, and cleaning and laundry. Finally, the total value of household production in Korea turned out to reach 171 trillion won which was value of 36% of GDP(482 trillion Won) in 1999.

  • The nuclear transplantation technique is known as the most potential and efficient method for producing large numbers of genetically identical animals from a single embryo and somatic cells. After Dolly was introduced in 1997, many scientists were amazed. A possibility came to a reality that live offspring could be produced with differentiated somatic cells from an adult animal. On the other side, many in the press and the sensationalists focused on the socially, ethically and scientifically unacceptable sides of the technology. In this article, the history, current status and prospects of the technological development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection, preactivation and micromanipulation of oocytes as capacious recipient cytoplasm, the adequate and benefitial preparation of multiple totipotent embryonic and somatic cells as donor nuclei, fusion of them and in vitro production of cloned embryos are very critical. Recently the overall efficiency of production of cloned embryos and offspring in livestock has been much improved. Cloning will also be a more efficient, faster and useful way of creating transgenic fetuses for gene therapies, gene pharming, organs for xenotransplantation by preselection and mass production of transgenic embryos and consequently improving the production efficiency in transgenic animals. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.

  • The Council Regulation (EEC) No 2092/91 of 24 Juni 1991 on organic production of agricultural products and indications referring thereto on agricultural products and foodstuffs. This Regulation describes the legal framework for agricultural products and foodstuffs obtained organically. The Regulation establishes a harmonized framework for the production, labelling and inspection of agricultural products and foodstuffs in order to increase consumer confidence in such products and ensure fair competition between producers. This article presents a study about inspection and certification system of organic production of agricultural products and foodstuffs in Germany. In order to guarantee respect for the rules of production, the Regulation provides for an inspection system to ensure that operators who produce, prepare or store organic products or import them from third countries notify the competent private and public authorities in the Member States of their activities. These inspection authorities must, at the very least, ensure application of the minimum inspection and precautionary measures laid down in Annex III to the Regulation. For the production of meat, the Regulation states that the Member States must guarantee the traceability of products throughout the production, processing and preparation chain.

  • In order to obtain the basic data for the preparation of yogurt containing ginseng component, the effect of ginseng component on cell growth of Lactobacillus casei YIT 9018 and on lactic acid production were investigated. Initial cell growth and acid production were markedly inhibited by the addition of ethanol extracts in the level of 8% into 15% skim milk. Crude saponin did not show any inhibitory effect on cell growth and acid production, but ether layer fraction showed inhibitory effect. It was thought to be more advantageous to add ginseng extracts after the fermentation of milk than before. The addition of ginseng extract at 8% level into liquid yogurt was most suitable in organoleptic test. Cell viability was not affected by the addition of ethanol extracts up to 8% level during storage of liquid yogurt.
