  • This research includes the prototype development of the master plan title. "National Research and Development Program Integrated Management System". The system collects the information of projects, supports the survey analysis evaluation, and pre budget coordination of national research and development programs, and provide the information service for people about the situation of the national research and development. The results of the research may be used as the base technologies in information service(information retrieval directory service) to manage all programs of national research and development in their life cycle and to allocate resources efficiently to the national research and development in the increasing tendency. tendency.

  • PURPOSE: Gene expression and apoptosis in testicular germ cells has been demonstrated in many transgenic animals. However, little is known about the transgenic pig and rates of apoptosis during spermatogenesis. METHODS : Morphological and biochemical features of apoptosis reported in other species were used to confirm that the TdT-mediated dUTP Nick end labeling (TUNEL) assay is an acceptable mothos for idendtification and quantification of apoptotic transgenic germ cells in histological tissue section from transgenic pig testis.

  • Mercury is an element of special concern for human health. Measurements of total mercury levels in fish have been taken into consideration to assess risk. In this study, the Antarctic toothfish Dissostichus mawsoni was evaluated as a potential safe food source through measurement of total mercury contents. Total mercury concentrations in Antarctic toothfish ranged from $0.101{\pm}0.047mg/kg$ to $0.139{\pm}0.075mg/kg$. The total mercury concentration was significantly correlated with macroscopic values including total fish length, weight, gonadosomatic index, and maturity (P < 0.01 or 0.05). Furthermore, according to the risk assessment, the total mercury body exposure rate from Antarctic toothfish ranged from 2.125% to 2.847% of the Provisional Tolerable Weekly Intake. Therefore, the Antarctic toothfish could be used as a potential safe seafood source.

  • Recently, soybean production and market price are unstable, even if demand of soybean is maintained. Diverse conditions such as climate change, a decrease in rural population, and consuming affect food industry. In this situation, food security is soaring as important key-word again, and MAFRA is promoting policies for improving soybean self-sufficiency with the goal of 40% until 2030. The point of policy is to extend a production and stabilize a demand for soybean with supporting large-scale soybean paddy-field complex. According to the background, soybean breeding and production research in NICS are proceeded with three parts. First, production improvement with soybean cultivation land enlargement and high-yield cultivar development. Various growth period soybean cultivars for double cropping, irrigation management technologies in paddy field, and hyper-yield and specific-region adaptable cultivar development. Second, reduction of production expense with mechanized cultivation and digital-based field management technologies. Third, consumer-friendly and high quality soybeans with high protein cultivar for alternative protein usage and high food process-ability for soy milk, tofu, soybean sprouts, and grain usage. Each part need to be combined and advanced to improve soybean industry and soybean self-sufficiency.
