This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

본 연구는 江原道 道有林과 太白市 市有林의 經營實態와 문제점을 파악하고 그에 대한 개선 방안을 제시하는데 있으며 연구 결과는 다음과 같다. 1. 江原道 道有林은 25,896ha, 太白市 公有林은 550ha였으며, 太白市 公有林 중 道有林은 470ha, 太白市 私有林은 80ha로서 그의 관리는 太白市에서 담당하고 있다. 2. 太白市 公有林 550ha를 현지 조사한 결과 창죽동 산 1-2번지의 443ha를 제외하고 나머지 107ha는 32개 지역으로 小規模로 分散되어 있었다. 3. 창죽동 산 1-2번지에 소재하고 있는 산림의 경우 석탄공사에서 대부를 받아 석탄을 채취하고 있으며, 나머지 公有林은 小規模로 分散되어 있어 山林經營 生産基盤이 취약하고 經營管理 상태는 매우 열악한 것으로 나타났다. 이와같은 점을 고려해 볼 때 太白市 公有林의 合理的인 經營을 위해서는, 첫째, 小規模로 分散되어 있는 公有林을 團地化 할 필요가 있고, 둘째, 體系的인 經營 計劃을 수립하여 지속적인 木材生産이 가능하도록 유도하여야 하며, 세째, 自然休養林 造成을 고려한 合理的 山地利用 體系를 강구하여야 할 것이다. The situation and the problems of the management of public forest owend by Kangweon provincial and Taebaek municipal governments were investigated throughout literature and field survey. The results were as follows; 1. Kangweon provincial forest is 25,896ha and Taebaek municipal forest is 550ha, which consists of Kangweon provincial forest, 470ha and municipal forest, 80ha. Taebaek city is responsible for the management of the province-owned forest in its administrative district in addition to its own forest. 2. Except San 1-2Changjookdong(443ha) which is leased by Dai Han Coal. Cooperation for mining coal, the remaining forest(107ha) consists of 32 scattered, small-area forest lands. 3. Due to small area and dispersal of municipal forest, the management base for forest production is not sound and the management at present is nearly absent. Based on these actual conditions, the following suggestions are provided for the rationalization for the municipal forest management. First, scattered, small-scale forests should be gathered to prepare a management complex. Second, the sustaining production of timber should be attained through the estblishment of systematic management plan. Third, the reasonable system for forest land utilization shoule be established in consideration of the recreational use of public forest.

In order to inhibit the growth of the malignant tumor, the development of various drugs against the malignant tumors has been archived. The combination of these drugs made the tumor therapy possible, but in many cases, secondary matastasis of the tumor to the other organs after its removal has been frequently reported. The angiostain, recently purified and cloned, not only promtes the angiogenesis of the tumor itself in the primary tumor but also inhibits the angiogenesis and metastasis of the secondary tumors. In this study, the nucleic acid sequences of the angiostatin was investigated. And the angiostain gene was expressed in a prokayotic expression system(E. coli) and a eukayotic expression system(Pichia pastoris). The angiostain gene was futher subcloned into 6 clones to characterize its biological activity. In the near future the biological activity and the biochemical property of the protein encoded by each clone will be elucidated.

Grapefruit seed extract(GFSE)의 여러가지 미생물에 대한 항균력과 물김치 저장 효과를 검토한 결과는 다음과 같다. 1. GFSE의 세균류에 대한 항균력에서 Vibrio속은 50ppm, Bacillus cereus와 Staphylococcus aureus는 30ppm, Serratia속은 10ppm 이상에서 균의 증식이 억제되었다. 2. 세균중 패혈증 원인균으로 알려진 Vibrio vu-Inificus에 대한 항균성은 nutrient broth에서 GFSE 30ppm 농도까지는 증식을 확인할 수 있었으나 50ppm 이상의 첨가에서는 72시간까지 균의 증식을 볼 수 없었다. 그리고 5% skim milk에서의 본 균에 대한 GFSE 살균력을 실험한 결과 5.2×10^5/ml에서 저장 120시간 후에는 GFSE농도 0, 10, 30, 50 및 100ppm에서 각각 9.6×10^3, 5.6×10^2, 48, 35/ml로 감소되어 GFSE농도 50ppm이상에서는 살균효과가 있음을 알 수 있었다. 3. 곰팡이류에 대한 항균력은 Aspergillus parasiticus가 100ppm, Aspergillus versicolor 50, Penicillium funiculosum 100, Pyrenochaeta terrestris 30 그리고 Trichoderma viride는 30ppm까지 증식하였으나 그 이상의 농도에서는 증식이 억제되었다. 4. 물김치에 GFSE를 각각 50, 100ppm 첨가하여 5℃와 20℃에서 저장하면서 pH변화를 확인한 결과 5℃에서는 20일과 25일, 20℃에서는 17일과 20일까지 pH변동이 거의 없어 물김치의 보존기간을 연장시킬수 있었다. This study was carried out to investigate the antimicrobial activity of the grapefruit seed extract (GFSE). The antimicrobial activity of GFSE was strong enough against such bacteria as Vibrio vulnificus, Vibrio fluvialis, Bacillus cereus, Staphylococcus aureus and Serratia sp. Growth of the above strains was inhibited by the GFSE'S concentration of 50 ppm. The growth of Vibrio vulnificus was completely inhibited by adding the 50 ppm GFSE to the nutrient broth medium with 3% NaCl. The cell counts of Vibrio vulnificus 5.2×10^5 at first in 5% skim milk containing GFSE 0, 10, 30, 50 and 100 ppm were reduced to 35, 48, 5.6×10^2, 5.3×10^3 and 9.6×10^3/ml after 120 hours, respectively. And growth of Aspergillus parasiticus, Aspergillus versicolor, Penicillium funiculosum, Pyrenochaeta terrestris and Trichoderma viride were inhibited by the concentration of GFSE 100, 50, 100, 10 and 30 ppm, respectively. The shelf life of Mulkimchi containing GFSE 50 and 100 ppm was 20 days longer than the control during storage at 5℃ and 20℃.

Korea experienced a unprecedented financial crisis in her history staring from 1997 through the following several years. The aftermath of the crisis still lingers upon many of the Korean companies as the world economy faces ever more turbulent changes with the start of the 21st century. The economic adversity is considered to have brought about the decline in the social responsibility of the Korean firms in general, and the propensity to disclose corporate environmental information in particular. This paper aims to investigate whether the environmental disclosures by Korean listed companies have undergone structural changes in terms of their disclosure behaviors in relation to selected fun characteristic variables including profitability, size, and capital structure. The results of the empirical analysis, however, show that except for the consistently positive relation between fan size and the propensity to disclose throughout the 3 years of 1999 through 2001, no other hypothesized relationships are validated.

The role of atmospheric radionuclide monitoring system is to measure the airborne radionuclide released from the nuclear explosive test or nuclear facility. Determination of the MDC(Minimum Detectable Concentration)s of 13 important radionuclides is essential for effective operation of the atmospheric radionuclide monitoring system under the CTBT(Comprehensive Test Ban Treaty) requirement. The radon and thron progeny exert a significant effect in determining the MDCs. The optimum decay and counting times were estimated through a series of experiments on the MDC. It was shown from the experimental results that for long-lived radionuclides, the MDCs were decreased slowly by elapsing the decay time, whereas the MDCs of short-lived radionuclides were increased continuously. In addition, the MDCs of most radionuclides are shown to decrease exponentially as counting time increases. By considering these analysis results, the optimum time parameters which could be satisfied with the CTBT technical requirements were determined. As above results, the optimum decay and counting times were selected 22 hour and 18 hour, respectively.
