        • 釜山市 有料公園의 植物 및 野鼠類相에 관한 硏究

          權相洙,南廷七,朴承範 동아대학교 환경문제연구소 1988 硏究報告 Vol.11 No.1

          This experiment was conducted in the three areas of pay park in pusan city for eight times from March to December in order to the aspect of plants and protect forest injury of field mice. The results were obtained as follows : 1. The numbers of flora in the survey area, the numbers of Family was appeared to 58, and the numbers of Sepcies was appeared to 184. The species of bload leaved evergreen trees of that was investigated totally to 25, and the it's ratio was found to 36% in comparison with the whole country. 2. The species of field mice were Apodemus agrarius coreae. Apodemus speciosus peninsulae, Clethrionomys rufocanus regulus and Crocidura suaveolens shantungensis. 3. The 66 individuals of field mice were collected from 2, 745 traps. 4. A total of 66 field mice collected were composed with 48.5% in Apodemus speciosus peninsulae, 34.8% in Crocidura suaveolens shantungensis, 9.1% in Apodemus agrarius coreae and 7.6% in Clethrionomys rufocanus regulue. 5. The locational proportions of field mice collected were 3.3%, 3.0% and 1.0% in station. Ⅱ, Ⅲ and Ⅰ, respectively. 6. Apodemus speciosus peninsulae and clethrionomys rufocanus regulue was not collected at the station Ⅰ. 7. The body weight ranged from 18 to 41.9g in Apodemus agrarius coreae, from 9 to 44.9g in Apodemus speciosus peninsulae, from 18 to 35.9g in clethrionomys rufocanus regulue. It's average weight was 27.8g in Apodemus agrarius coreae, 28.4g in Apodemus speciosus peninsulae and 23.7g in clethrionomys rufocanus regulue. 8. The ratio of female to male of field mice was 0.67 to 0.33 in apodemus agrarius careae, 0.47 to 0.53 in Apodemus speciosus peninsulae and 0.4 to 0.6 in Clethrionomys rufocanus regulue. 9. The average body length of field mice was 95.97㎜ in Apodemus speciosus peninsulae, 95.20㎜ in Clethrionomys rufocanus regulue and 94.83㎜ in Apodemus agrarius coreae. 10. The everage tail length of field mice was 94.84㎜ in Apodemus speciosus peninsulae, 76.67㎜ in Apodemus agrarius coreae and 37.20㎜ in Clethronomys rufocanus regulue. 11. The everage ear length of field mice was 15.83㎜ in Apodemus speciosus peninsulae, 14.08㎜ in Apodemus agrarius coreae and 13.80㎜ in Clethrionomys rufocanus regulue. 12. The breeding period of field mice was between March and September in Pusan area. 13. The average fetal number of field mice was 5.1 in Apodemus speciosus peninsulae, 4.5 in Crocidura suaveolens shantungensis and 3.0 in Apodemus agrarius coreae.

          비정상 옵션가격의 현물가격 선도효과

          권상수 한국산업경제학회 2009 산업경제연구 Vol.22 No.2

          본 연구는 옵션거래량 세계 1위인 KOSPI200 옵션시장을 대상으로 옵션가격의 기본 특성인 단조성과 완전상관성 위반현상이 미래 현물가격 선도효과를 가지는지 여부를 검증하였다. 즉, 옵션시장에서 기초자산 가격이 상승(하락)하면 유럽형 콜옵션의 가격은 상승(하락)하고, 유럽형 풋옵션의 가격은 하락(상승)하는 단조성의 특성과 옵션가격은 행사가격과 만기에 관계없이 기초자산 가격과 완벽한 상관관계를 가진다는 완전상관성의 기본특성을 위반한 사례를 조사한 후 동 위반비율의 현물 선도효과를 조사하였다. 분석기간은 2002년부터 2006년까지 5년간이며 KOSPI200 옵션 1분 데이터를 사용하였으며 본 연구의 주요 결과는 다음과 같다. 분석 결과, KOSP1200 옵션시장에서 옵션가격의 단조성과 완전상관성의 특성을 위반한 비정상 옵션가격 변화에도 미래 현물가격에 관한 중요한 정보가 있음을 확인하였다. 유형별 위반비율과 미래 현물지수 변화와는 일정한 관계를 가지고 있으며 콜옵션과 풋옵션의 유형별 위반비율의 변화를 통해 미리 현물지수 변화를 예상할 수 있음을 확인하였다. 그리고 위반비율이 높은 그룹이 낮은 그룹에 비해 또한 위반비율의 변화량이 클수록 현물 선도효자가 더욱 크게 나타났다. 그리고 이같은 위반현상의 현물선도효과는 현물가격에 비해 옵션가격의 현물선도효과가 더욱 크기 때문에 발생하는 현상임을 확인할 수 있었다. It is well known that the option prices have the monotonicity property and the perfect correlation property. According to the monotonicity property, the value of a European call (put) should be nondecreasing (nonincreasing) in the underlying asset price. The perfect correlation property assumes that all option prices, regardless of moneyness and maturity, are perfectly correlated with each other and with the underlying asset. In this article, we examine whether the violations of the basic properties of the option prices exist in one minute interval basis in the KOSPI200 option market and test whether the violations have the predicting power of the future spot index returns. The sample period is from January 2. 2002 to December 28. 2006. Our important finding may be summarized as follows. The irregular option prices movements which violated the basic properties of the option prices have the important informational contents regarding the future spot index return. The various types of the violations have consistent relationships with the future spot index movements. The future spot index movements also can be forecasted based on the change of the violation rate of the basic properties. The higher violation rate group has the higher lead effect for the future index return than the lower violation rate group. We confirmed that the lead-effects of the violation rate for the future spot return come from the fact that option prices lead the spot prices.

          權相洙 東亞大學校 1966 東亞論叢 Vol.3 No.-

          The culting process of the tube plants like Iris is mostly concern to the dent of planting as a condition of hardening the tissue, and to maintain the hardners of tender tube plants tissue it is main gurpass to press down to bloom on culting process. The followings are mastly effective according to the main experiment, 1) Plants no.4 on figure 1 by plot table. 2) Plants no.3 on figure 2 by plot table.
