The wind power prediction information is necessary for electric power system operation and electricity power market which is allowed to participate the wind power. In this study, a real-time wind power prediction system is designed for the real application in electric power system in Jeju. The wind power prediction system is composed of meteorological forecasting model, calculation module of wind power output and visualization system. The result of this study is expected to contribute to increase the penetration of the wind power generation into the electric power system.

The wind power prediction system is composed of a meteorological forecasting module, calculation module of wind power output and HMI(Human Machine Interface) visualization system. The final information from this system is a short-term (6hr ahead) and mid-term (48hr ahead) wind power prediction value. The meteorological forecasting module for wind speed and direction forecasting is a combination of physical and statistical model. In this system, the WRF(Weather Research and Forecasting) model, which is a three-dimensional numerical weather model, is used as the physical model and the GFS(Global Forecasting System) models is used for initial condition forecasting. The 100m resolution terrain data is used to improve the accuracy of this system. In addition, optimization of the physical model carried out using historic weather data in Jeju. The mid-term prediction value from the physical model is used in the statistical method for a short-term prediction. The final power prediction is calculated using an optimal adjustment between the currently observed data and data predicted from the power curve model. The final wind power prediction value is provided to customs using a HMI visualization system. The aim of this study is to further improve the accuracy of this prediction system and develop a practical system for power system operation and the energy market in the Smart-Grid.

N/A The in vitro effect of bisphenol A (BPA) on ovarian steroidogenesis of the longchin goby (Chasmichthys dolichognathus) was investigated. Oocytes taken during the maturing phase (vitellogenic, fully vitellogenic or germinal vesicle breakdown stage) were incubated with BPA (100 ng/mL) in the presence of exogenous precursor ³H-17α hydroxyprogesterone (³H-17αOHP). Steroids were extracted from the media and the isolated oocytes, and the extracts were separated and identified by thin layer chromatography and gas chromatography-mass spectrometry. The identities of the major metabolites were progestogens [17α-hydroxy,20adihydroprogesterone (17α20αOHP) and 17α-hydroxy,20β-dihydroprogesterone (17α20βOHP)], androgens [androstenedione (A4) and testosterone (T)] and estrogens [estrone (E₁) and estradiol-17β (E₂)]. BPA treatment inhibited production of estrogens in all the maturing phases and progestogens in the germinal vesicle migrating stage. Percentage yield of estrogens was decreased with increased yield of androgens. In conclusion, BPA had an inhibitory effect on the conversion of ³H-17αOHP to estrogens and progestogens. These results demonstrate that BPA can act either estrogenic or anti-estrogenic effects.

The study tries to suggest one kind of method for measuring expost cummulative fisheries damages caused by a large scale coastal reclamation. The situation of fisheries damages which the paper is considering is different from those of general cases:the latter is a priori investigation but the former is a posteriori one. Therefore we need a different approach for exact measurement of such kind of fisheries damages. The key contribution of the paper is to try to estimate a decreasing production function using the results of present investigation and several statistical data about our coastal fisheries productivity and environmental deterioration. Using the function, the paper tries to derive the expected catch amount and damage amount.
