This paper uses a survey data to analyze the age-specific fertility rates, age-specific cumulative fertility rates, and ages of marriage of the five birth cohorts of Korean women born in the 1940s and thereafter. It was found that later cohorts reach their highest age-specific fertility rate at higher ages than earlier cohorts. The age-specific cumulative fertility rates of the 1950s and 1960 cohorts were found to be much lower than those of the immediately preceding cohorts, while those of the 1970s and 1980s cohorts were not different from those of the 1960s cohorts. Women belonging to later cohorts were found to get married at relatively higher ages. The estimation results of the hazard model show that women belonging to later cohorts and those with more schooling have a tendency to get married at higher ages. The effect of the birth cohorts is thought to be due to the economic, social, and cultural changes in Korea during the late 50 years or so. The time interval between a woman‘s marriage and first birth was found not to be affected by either the year of marriage or that of her birth. Also, those who remained employed for some time around their marriage and those with low schooling were found to have a lower first child birth hazard, which implies that married women’s employment status and family income play an important role in their decisions on childbirth.

The aim of this thesis is to clarify the application of Derrida's 'Deconstruction' theory on the contemporary costume. Derrida's theory of 'Deconstruction' took into the 'decentring' concept which deconstructed the subjects i.e., Occidentalism, Elitecentrism, logocentrism, mancentrism etc.; it deconstructed the dichotomy that had been expressed in the traditional occidental metaphysics, by raising the isolated ones such as the Orient, sub-culture, ir- rationality, madness, woman etc. Summarizing the conclusion of this thesis as follows, 1. The impact of 'Deconstruction' from the inside is to be seen in the principles of intertextuality of the costume, therefore it has shown the bisexual costume by interacting gender, and the costume by mixing time, place and occasion. 2. $\ulcorner$Dis$\lrcorner$ deft phenomena which shows the concept of escape from the center were presented as decentring, dislocation, discomposition, disorder. 3. Undecidability principle resulted in the undecidable presentation in the wearing styles such as wearing, unwearing, layering. Contemporary costume by the 'Deconstruction' from the inside regards costume as a dynamic text, which has attempted the interaction with the other genres. It deconstructed the teleology of the costume function, and it accepts all the various aesthetic principles.

주식시장에서 환율위험프리미엄의 존재유무는 기업의 투자 및 자본조달, 외환헤징재무활동, 개인의 투자전략 등에 중요한 영향을 미치게 된다. 본 연구에서는 차익거래모형을 이용하여 우리나라 주식시장에서 환율위험노출을 측정하고, 그 환율위험이 시장에서 보상되는 위험인가를 검정한다. 전체 표본기간은 1980년부터 1998년까지이며, 외환자유화와 자본시장 개방이 본격적으로 이루어진 1992년 이전과 이후를 하위기간으로 구분하여 분석하였다. 표본하위기간의 설정, 다각적인 환율위험요인 측정, 다양한 모형설정과 복수의 통계추정방법의 적용 등을 통하여 환율위험 프리미엄의 유무에 관련된 신뢰성있는 결론을 도출하고자 하였다. 1980년대 표본전기 하위기간에는 주식시장에서 통계적으로 유의한 환율위험노출을 확인하기 어려웠으나, 외환자유화와 자산시장개방이 본격화된 표본 후기 하위기간에는 뚜렷한 환율위험 의 존재를 확인할 수 있었다. 후기 하위기간을 대상으로 시장위험과 실효환율위험만을 포함한 차익거래모형을 적용하였을 때에 통계적으로 유의한 환율위험 프리미엄이 확인되었다. 그러나 달러환율과 엔화환율위험을 별개의 환율위험으로 설정한 경우 각 환율위험에 개별적으로나 결합적으로 통계적으로 유의한 위험프리미엄을 발견하지 못하였다. 더구나, 실효환율위험에 추가하여 산업생산위험, 인플레이션위험, 기업부도위험 등의 기본적 경제요인 위험을 함께 통제변수로서 포함하여 차익거래모형을 적용하였을 때에도 환율위험 프리미엄은 존재하지 않았다.
