  • The purpose of this paper is to analyse the change in the productivity of Korean life insurance industry by Generalized Malmquist productivity indices. Generalized Malmquist indices will be decomposed into three components such as pure efficiency change, scale efficiency change, and technical change. The principal findings indicate an overall increase in productivity driven more by technical progress than pure technical efficiency and scale efficiency.

  • With many changes such as the increase in telemarketing, internet marketing and enforcement of bancassurance, the Korean life insurance companies have undergone a startling transformation. The purpose of this paper is to measure and analyse the static/dynamic efficiency of Korean life insurance companies employing Data Envelopment Analysis(DEA). As the result of the static efficiency analysis, we provide CCR, BCC and scale efficiency, return to scale, and reference set of Korean life insurance companies in 2004. And we also describe about the trend and stability of their efficiency for 7 years(1998-2004) in the dynamic efficiency analysis.

The Comparative Study on the Cosmic Life as the Inter-Relational Metaphor of the Ultimate Reality in East and West (서양의 영(Spirit)과 동양의 기철학과의 대화 : 내적 관계성의 메타포와 우주적 생명을 중심으로)

  • The purpose of this paper is to create an inter-religious dialogue between the Western Christian concept of the spirit and Eastern ch'i philosophy within the category of panentheism. The Hebrew term ruah means 'moving air' and 'wind' which derive from the particular experience of the ancient Hebrew people living in the desert. The Greek pnuema also means 'life' and 'wind' which denote the natural power. Both ruah and pneuma consist of the main idea of the spirit exploring the symbol of relationality of the divine in Western tradition. Eastern ch'i philosophy indicates a vital force for keeping the body and soul alive, which is unconscious and spontaneous. Ch'i as a vital force constitutes cosmogony and cosmology with the constant movement of yin and yang. Yin and Yang as representing earth and heaven are dynamic breaths, blending harmoniously to become all existence. The ethical implication of the inter-religious dialogue between the spirit and ch'i would be the integration and interconnection of heaven, earth, and human beings. The dialogue suggests becoming one body with nature and human community through embodying the non-dualistic spirit of life. The inter-relationality means that since all modalities of existence are made of the cosmic life, human beings are part of the divine cosmic process. This is related to degree of spirituality in the entire chain of being: rocks, trees, animals, humans, and goods represent different levels of spirituality based on the varying composition of the spirit and ch'i. All beings that internally embody with the spirit and ch'i are organically inter-connected, and they are integral part of a continuous process of transformation of life towards holistic liberation of human and nature community.

  • 기후변화에 따른 기상이변의 동시다발적인 발현은 농촌 지역의 홍수 발생 빈도를 증가시키고 있다. 현재의 기후시스템은 과거의 강우빈도를 기준으로 산정한 설계기준을 벗어나는 강우 사상을 빈번하게 발생시키므로 설계변수의 불확실성을 보다 합리적인 방법으로 정량화할 필요가 있다. 본 연구의 목적은 기후변화에 대응하여 확률론을 이용한 농업용 저수지의 홍수 취약성을 산정하는 데 있다. 먼저 홍수 취약성 해석에 필요한 과거와 미래 수문 자료를 수집하고 전처리 과정을 통해 해석에 적합한 자료로 구축하였다. 설계변수의 불확실성을 분석하기 위해 지속시간별 최대강우량, 유입 설계홍수량에 대해 부트스트랩 (bootstrap) 기법을 적용하여 자료를 재추출하였다. 부트스트 랩은 표본집단의 확률분포에 대해 가정을 하지 않고 표본집단의 통계적 특성을 이용하여 모집단의 통계적 추론을 할 수 있는 비모수적인 리샘플링 기법이다. 부트스트랩 추론은 표본집단의 추정치, 편의, 표준오차를 산정하고 신뢰구간을 추정한다. 부트스트랩 추론을 통해 산정하는 신뢰수준을 이용하여 농업용 저수지의 홍수 취약성을 산정하였다. 본 연구는 설계변수에 내재하는 불확실성을 부트스트랩 기법을 이용하여 정량화하고 확률적인 값을 가지는 홍수 취약성으로 산정하여 제시할 수 있다.
