본 연구에서는 Hasbrouck(1995, 2002)의 정보공헌도(information share) 기법을 이용하여 역내 외환시장의 원/달러 현물환율과 선도환율, 역외 통화시장의 원/달러 NDF 환율의 장기적 공통추세를 중심으로 한 상호 가격발견의 동학을 분석한다. 분석 결과는 다음과 같다. 첫째 NDF 시장에 비해 역내 외환시장에서의 현물환이나 선물환이 주도적인 가격발견의 기능을 하고 있다. 둘째, 원화 가치는 글로벌 위기시 국내외 정보에 더욱 민감해지는데, 위기의 시기에 있어 NDF의 가격발견 역할이 증대된다. 하지만, 역내 시장의 가격발견상 역할과 비중을 능가하지는 못한다. 결국, NDF 시장이 이른바 왝더독(wag the dog)을 촉발시키는 요인으로 보기 어렵다. 이러한 결과는 NDF 시장에 대한 부정적 인식과 시각을 지닌 시장 참여자나 정책당국자가 참고할 필요가 있다. 나아가, NDF 시장이 원화에 대한 24시간 거래를 가능케 하고, 역내 외환시장의 현물환율이나 선물환율에 대한 가격발견 기능이 있다는 것은 역내 외환 시장에서 주요 환율 지표 결정에 있어 불확실성을 줄이는 역할을 하고 있는 것을 시사한다. Using Hasbrouck`s (1995, 2002) information share method, we examine the mutual price discovery dynamics among Won/Dollar spot, forward, and NDF exchange rates in on- and off-shore FX markets. Our findings include : (i) During the entire period, the mutual price discovery between on-shore FX market and off-shore NDF market are significantly led by on-shore Won-Dollar spot and forward exchange rates. (ii) Within the period around the global crisis, NDF exchange rates have mutual influence on the price discovery, which is expecially greater than the any other period. The results show Won-Dollar spot exchange rate fluctuations during the global crisis are greatly affected by external factors of the international financial markets. Not only that, but off-shore NDF trading promptly reflects the price information of KRW on the factors.

현장계측에 의한 농업용저수지 제체의 안정관리기법

이달원,오범환 충남대학교 농업과학연구소 2003 농업과학연구 Vol.30 No.2

본 연구는 연약지반상에 축조되는 농업용 저수지의 합리적인 안정관리의 기준을 수립하기 위하여 현장게측결과를 기초로 시공중 또는 완공후에 측방유동 등으로 인하여 국부적인 전단파괴 가능성을 현장계측치로부터 비교분석하여 다음과 같은 결론을 얻었다. 1. 한계평형법에 의해 안전율을 비교하면 Spencer방법과 간이 Bishop방법은 거의 유사하게 나타났고, 간이 Janbu 방법은 약간 작게 나타났다. Spencer방법은 흙의 활동부분에 대해 힘과 모멘트 두 평형방정식을 만족시키는 해석방법이므로 저수지의 안정성을 해석하는데는 합리적이라 판단된다. 2. 수평변위는 물리적 성질의 변곡점이 형성되는 부분에서 급증하였고, 성토의 안정관리는 각 토층의 경계부분에서 가장 불안정한 상태로 나타나므로 분석시 가장 우선적으로 검토하여야 한다. 3. 수평변위속도에 의한 안정성 평가방법은 파괴 가능성을 미리 예측하는데 상당히 효율적인 방법이라고 판단되고, 전단파괴 가능성이 높은 무처리지반에서의 안전율의 기준은 처리지반보다도 신중하게 선정하여야 할 것으로 판단된다. 4. 점증하중에 의한 시공중 안정성을 계측자료를 이용하여 분석한 결과, 파괴기준선에 접근하여 위험가능성이 있는 부분도 있었으나 성토체는 안정한 것으로 확인되어 안정관리상 파괴기준선으로 안정성을 평가하는 것보다는 곡선의 기울기로 판단하는 것이 합리적이다. This study was performed to suggest a rational method for the stability evaluation of agricultural reservoir in the very soft ground. The stability methods for agricultural reservoir was used to compare and analyze with various condition by limit equilibrium method. The behavior of settlement-displacement obtained by field monitoring system was used to compare and analyze with various stability methods, and to investigate the applicability of the methods for stability evaluation of agricultural reservoir. The horizontal displacement was abruptly increased when physical properties of soft clay reached its maximum values and therefore, the values of these properties could be used to the fundamental data for stability evaluation. The evaluation of the stability of agricultural reservoir was suggested to use the inclination of curve rather than critical line.

In an effort to optimize tissue culture responses of zoysiagrass (Zoysia japonica Steud.) for genetic transformation, factors affecting callus induction and plant regeneration were investigated. MS medium containing 3 ㎎/L 2,4-D was optimal for embryogenic callus induction from mature seed. The plant regeneration frequency of 73.3% was observed when embryogenic calli induced in this medium were transferred to N6 medium supplemented with 0.1 ㎎/L 2,4-D and 5 ㎎/L BA. Among several basic media, MS and N6 medium were optimal for callus induction and plant regeneration, respectively. Regenerated plants were grown normally when shoots transplanted to the soil. A rapid and efficient plant regeneration system established in this study will be useful for molecular breeding of turfgrass through genetic transformation.

Present study was undertaken in order to clarify the species and infection rate of internal parasites in Korean native goats. Abomasum of 100 goats slaughtered in Daejun and abomasum, intestinal tracts, and pancreata of 40 goats slaughtered in Taegu prefecture were inspected. The parasites recovered were classified morphologically with following results. 1) A total of 7 species of parasite was identified. Their habitats and infection rates were as follows; Abomasum-Haemonchus contortus: 20% in Taegu and 42% in Daejun, and Trichostrongylus sp. : 2.5% in Taegu and 3% in Daejun. Small intestine-Moniezia expansa: 12.5%. Large intesine Oesophagostomum columbianum: 27.5%, Oesophagostomum venulosum: 17.5%, and Trichuris ovis: 5%. Pancreas-Eurytrema coelomaticum: 15%. 2) Characteristic nodule formation on the walls of cecum, colon, and ileum was observed in 5 out of 11 goats infected with Oesophagostomum columbianum. No nodule formation, however, was observable in goats infected with Oesophagostomum venulosum. 3) the maximum worm burdens of Oesophagostomum columbianum, Eurytrema coelomaticum, and Haemonchus contortus were higher (above 83) than those of the other parasites. 4) the numbers of female nematodes were greater than of male except Oesophagostomum venulosum.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

Genetic analysis of the variabilities of deleterious genes of Drosophila melanogaster in Sasang natural population was undertaken. Drosophila melanogaster used in this experiment was collected randomly for this analysis. The results of the experiment concerning the genetic variabilities of viability and sterility of the third chromosomes were as follows: 1) The frequency of phenotypic sterility was 7.0 percent for males in 200 lines from the natural population. 2) Variations on the viability of homozygotes for the third chromosomes were estimated to be 14.0 percent for lethals, 6.5 percent for semilethals, and 13.4 percent and 66.1 percent, respectively, for subvitals and normal chromosomes including supervital ones. 3) Allelic rate between lethal genes extracted from the natural population was 1.84 percent. 4) The frequencies of sterile chromosome were 0.9 percent in females and 1.8 percent in males. 5) Elimination frequency caused by deleterious genes in homozygotes for the third chromosome was estimated to be 0.0008. This frequency is similar to the frequency of the second chromosome.

This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.
