본 논문은 주가지수 선물과 옵션의 만기일이 주식시장에 어떠한 영향을 미치는가에 대한 분석을 통해 한국주식시장에서 만기일 효과가 존재하는지를 검증한다. 주가지수를 이용한 기존의 논문과는 달리 만기일에 현물 주식시장의 움직임을 개별 종목별로 분석했다는 점에서 본 논문은 차별성을 지닌다. 주가지수는 시장 움직임의 평균으로 개별 종목의 고유한 특성을 반영하지 못하기 때문에 주가지수를 이용한 분석은 만기일 효과를 해석하고 그 원인을 분석하는데 한계를 지니고 있다. 분석 결과 한국주식시장에서 선물 만기일 효과는 분명히 존재하지만, 옵션 만기일 효과는 뚜렷하지 않은 것으로 드러났다. 선물 만기일에 KOSPI 200 지수와 개별 종목은 가격상승 압력이 존재하고, 변동성과 거래량이 증가하며, 만기일 다음날 수익률은 반전하는 경향이 있는 것으로 나타났다. 그러나 비교표본인 NON-KOSPI 200 지수와 개별 종목에서 만기일 효과가 존재한다고 할 만한 증거를 찾지 못했다. 만기일 효과가 시장 전체적으로 나타나는 것처럼 보이지만 KOSPI 200에 속하는 대규모 기업에 한정되며, 장 후반에 집중적으로 나타난다는 사실은 프로그램 매매와 만기일의 결제제도가 만기일 효과의 간접적 원인임을 시사한다. 또한 만기일 다음날 가격이 반전하는 현상이 KOSPI 200에 속하는 대규모 기업에 한정되어 나타나는 사실은 만기일 효과가 새로운 정보의 반영에 의한 정보 효과(information effects)가 아니라 일시적 거래불균형에 의한 유동성 효과(liquidity effects)임을 보여주는 증거가 된다.

이 연구는 서로 다른 교과의 교사들로 이루어진 학습공동체 활동 중 아이디어 융합과정에서의 교역지대의 형성과 진화 양상을 알아보고, 교역지대 경험과정에서 느낀 어려움과 변화된 교사들의 인식을 파악하고자 하였다. 연구목적 달성을 위하여 남부권 소재 중학교의 교내 학습공동체인'STEAM 교사 연구회'소속 교사들에 대해 참여관찰, 심층면담 그리고 반성적 에세이 작성 및 검토가 이루어졌다. 연구 결과, 'STEAM 교사 연구회'소속 교사들은 융합형 교수-학습 계획안 작성이라는 아이디어 융합 과정에서 전문성 교환을 위하여 성공적으로 교역지대를 형성하였으며, 전교역지대, 엘리트 통제에 의한 교역지대, 경계대상이 있는 교역지대, 공유된 정신모형의 교역지대의 형태로 형성되고 진화된 것으로 나타났다. 세부적으로 살펴보면 전교역지대의 하위 단계로는'아이디어 융합의 당위성 확인',' 개인적 해석과정',' 모두가 공급자'가 나타났고, 엘리트 통제에 의한 교역지대에서 나타난 하위단계로'기여적 전문성의 등장'과 '제도적 힘의 불균형'이 있었으며, 경계대상이 있는 교역지대에서는 하위단계로'상호작용적 전문성의 등장','공약불가능 상태의 확인', '경계물 및 매개물을 통한 교집합 형성',' 중간언어 사용 및 의미협상을 통한 공약불가능의 극복노력'이 있었다. 마지막으로 '공유된 정신모형의 교역지대'에서는 하위단계로서 '교역지대 공간의 유지 노력'및'형성된 교역지대 공간의 확장시도'가 나타났다. 또한 교역지대 형성과정에서 교사들이 경험한 어려움들은'교과간의 문화와 견해 차이',' 융합동기의 결여',' 융합의 주도권과 융합을 위한 억지 요소 도입',' 용어의 불통'이 있었다. 그러나'STEAM 교사 연구회'교사들의 교역지대 경험 후'융합의 필요성에 대한 새로운 인식', '교사공동체 활동에 대한 긍정적 인식과 실천의지',' 타 교과 및 자신의 교수-학습에 대한 관점의 변화', '융합에 대한 막연한 공포감 해소와 자신감 획득'과 같은 인식의 전환을 경험할 수 있었다. 이 연구 결과 도출된 교역지대 모형은 교과 융합을 위한 자율적 교사 학습공동체 활동에 시사점을 줄 수 있다.

In this paper, we propose the rough set approach to extract trading rules able to discriminate between bullish and bearish markets in stock market. The rough set approach is very valuable to extract trading rules. First, it does not make any assumption about the distribution of the data. Second, it not only handles noise well, but also eliminates irrelevant factors. In addition, the rough set approach appropriate for detecting stock market timing because this approach does not generate the signal for trade when the pattern of market is uncertain. The experimental results are encouraging and prove the usefulness of the rough set approach for stock market analysis with respect to profitability.

The X-12-ARIMA program was utilized on the analysis of the time series trend on 76 Korean industrial activities data in order to ensure that the trading day effect adjustment as well as the seasonal effect adjustment is needed to extract the fundamental trend-cycle factors from various economic time series data. The trading day effect is strongly correlated with the activity of production and shipping but not with the activity of inventory. Furthermore, the industrial activities were classified with respect to the sensitivity on the tranding day effect.
