Over 96.2% of the agricultural water in Jeju Island is obtained from groundwater and there are quite distinct characteristics of agricultural water demand/supply spatially because of regional and seasonal differences in cropping system and rainfall amount. Land use for cultivating crops is expected to decrease 7.4% (4,215 ha) in 2020 compared to 2010, while market garden including various vegetable crop types having high water demand is increasing over the Island, especially western area having lower rainfall amount compared to southern area. On the other hand, land use for fruit including citrus and mandarin having low water demand is widely distributed over southern and northern part having higher rainfall amount. The agricultural water demand of $1,214{\times}10^3\;m^3/day$ in 2020 is estimated about 1.39 times compared to groundwater supply capacity of $874{\times}10^3\;m^3/day$ in 2010 with 42.4% of eastern, 103.1% of western, 61.9% of southern, and 77.0% of northern region. Moreover, net secured amount of agricultural groundwater would be expected to be much smaller due to regional disparity of water demand/supply, the lack of linkage system between the agricultural water supply facilities, and high percentage of private wells. Therefore, it is necessary to ensure the total net secured amount of agricultural groundwater to overcome the expected regional discrepancy of water demand and supply by establishing policy alternative of regional water supply plan over the Island, including linkage system between wells, water tank enlargement, private wells maintenance and public wells development, and continuous enlargement of rainwater utilization facilities.

There is a discrepancy in opinion regarding geological age of Okchon system among professor C.M. Son and the writer who represent the two school of thought in precambrian stratigraphy in Korea as a whole. This brief article is a reply to the recent paper by C.M. Son titled "On the geological age of the Ogcheon Group" The discrepancy in opinion on the age Okchon system is based mainly on the difference in opinion about the age of Majeonri, Hwachonri and Kounri formations, the age of which professor Son believes as post-ordovician and regards them as a part of the Great Limestone series and the base of the Ogchon Group. The writer is in a opinion that Okchon system belong to precambrian in age and Majeonri-, Hwachonri-, and Kounri formations are the same formation composing an upper member of Okchon system. The writer's opinion is based on the facts that i) stratigraphical sequence of Okchon system established by the writer was accepted by C.M. Son who used believed the reverse order in sequence and confessed his mistake in his article; and ii) regional stratigraphy and structure strongly support's to writer's opinion. The writer pointed out and discussed in this paper various facts which do not support Son's idea by any means.

In order to investigate the in vivo effect of $^{60}Co$ radiation on rabbit liver, the uptake ratio and regional excretory value in hepatocytes and Kupffer cells were estimated during acute and chronic hepatic injuries. The left lobe of liver was irradiated at 15 Gy or 30 Gy with a single dose and subsequent changes were analysed with a seial nuclear medicine imaging by using $^{99m}Tc-phytate,\;^{99m}Tc-DISIDA\;and\;^{99m}Tc-HSA$ and resulting data were computerized. The degree of hepatic damage, duration of the injury, and recovery pattern after the irradation were in agreement with the findings of other investigations. However, out values were more quantitative evacuation than those of other publications. Recovery of decreased uptake of $^{99m}Tc-phytate$ was delayed approximately $2{\sim}3$ days later than that of $^{99m}Tc-DISIDA$. In acute radiation induced injury, the results demonstrated that the recovery of Kupffer cells was delayed more than that of hepatocytes. This discrepancy was considered due to the differences in repair activities between these cell types. The decreased of regional excretory value in irradiated area was found to be dose-dependent but had no corelation with regional uptakes of DISIDA and phytate. The decreased of regional excretory value observed in non-irradiated region suggested that irradiated liver might induce an indirect effect.

The hypo-salinity effects on fertilized eggs, embryos and larvae were investigated in olive flounder (Paralichthys olivaceus) obtained from hatcheries in Cheju-Island, Yeosu and Chungnam. Those were treated to eight concentration; 0, 3.4, 6.7, 10.1, 13.4, 20.2, 27.4 and 33.6 ‰. It was not discrepancy in the survival rate and hatching success rate of fertilized embryos obtained from different regions. Also, in the larvae, the regional difference was not appeared. The survival rate and hatching ability of embryos significantly diminished in the lower groups than 13.4 ‰ compared to 33.6 ‰. After fertilization, namely embryos are tolerant of a wide range of salinity (13.4 - 33.6 ‰). Reduced salinity induced an increase of the malformed embryo and larvae including various deformities; irregular embryos membrane (or yolk sac depression), fin erosion and swim bladder inflation in the flounder embryo. The hatching success of embryos was significantly reduced in lower salinity than 13.4 ‰. Notably, the reduction of larval survival rate significantly was observed in ≤10.1 ‰ treated groups with the same manner of survival rates of the embryos. Additionally, olive flounder was found to be adequate model for measuring external impulses because there are no the regional differences.

This study was investigated the estimation of VOCs (Volatile Organic Compounds) emission from a gas station tank. To improve the atmosphere environmental quality near the gas station, the installation of vapor recovery system has been expanded recently. Therefore, it was necessary to calculate VOCs emissions from the gas station tank with vapor recovery systems for evaluation of their performance. The VOCs emissions are difficult to measure directly because of various sources and irregularly emission by pressure rise. In this study, VOCs emissions were estimated by simple calculation based on the equation of state for measured pressure, temperature and volume of a gasoline tank at a gas station. The result confirmed that the present national emission factor did not have significant discrepancy with the calculated value.

MODIS LAI product has been one of key variable for analyzing the quantitative aspects of terrestrial ecology at global scale. This study was designed to validate MODIS global LAI product for regional application. To examine the quality of MODIS LAI data, we developed a reference LAI surface that was derived by relating the ground LAI measurements to Landsat ETM+ reflectance. The study area, the Kwangneung Experiment Forest in Korea, covers mixed deciduous and coniferous species of temperate forest. Ground measurements of LAI were conducted at 30 sample plots by using a photo-optical instrument during the growing season of 2002. Ground measured LAI data were then related to the ETM+ reflectance to produce a continuous map of LAI surface over the study area. From the comparison between the MODIS LAI and the reference LAI, it was found that the MODIS LAI values were slightly higher at the forestland. Considering the limitations of producing the reference LAI surface and the uncertainty of the input variable for the MODIS LAI algorithm, such small discrepancy mal not be significant.

신흥시장국의 약진과 함께 세계경제의 다극화체제(Multipolar World Economy)가 뚜렷해지면서 새롭게 부상하는 신흥시장국의 경제력을 반영하여 이들 국가의 통화를 국제화하려는 시도가 전개되고 있다. 한편 현재 국제통화의 흐름을 보면 그 자격요건과 실질적 위상의 불일치가 존재함을 발견할 수 있는데, 신흥시장국의 통화는 세계경제에서 차지하는 경제규모 및 교역량에 비해 실제위상이 과소평가된 상황이다. 본 연구에서는 5개 주요 국제통화(달러, 엔, 유로, 파운드, 스위스프랑)를 대상으로 국제통화의 결정요인에 대한 실증분석을 시도하였다. 분석결과 경제규모, 무역규모, 그리고 물가 및 환율 안정이 가장 크게 영향을 미치는 것으로 나타났다. 이 결과를 바탕으로 향후 국제통화의 모습을 전망해 볼 때 중국 위안화가 새로운 국제통화로 부상할 가능성이 큰 것으로 확인되었다. 따라서 우리나라는 중국 위안화의 국제화 가능성을 염두에 두고 역내 경제통합과 더 나아가 통화통합 등의 이슈를 선점할 필요가 있다.
