In this paper, I pose a problem for Hitchcock's arguments for two concepts of effects that are intended to explicate double causal effects, and put forth a theory that is intended not just to meet the problem but also to accommodate Hitchcock's theory and Eells' theory both. First, I introduce an example of dual causal effects, and examine the accounts of Otte(1985) and Eells(1987) on how to explicate the dual effects. I show that their accounts of the dual effects help us understand the problem of dual effects and see how different it is for Cartwright(1979, 1989, 1995), Eells(1991, 1995), and Hitchcock(2001a) to meet the problem. Second, I introduce two concepts of effects on Hitchcock(2001a), that is, net effect and component effect that are allegedly analogous to two effects of structural equation model. Third, I reveal the significance of homogeneous subpopulation and causal interaction regarding the problem of dual effects while examining Cartwright's theory and Elles' theory. Fourth, I critically examine the two concepts of effects on Hitchcock and argue against Hitchcock's criticism of Eells' theory. Fifth, I take a moderator variable of structural equation model and a moderator effect into the probabilistic theory of causality, and formally generalize causal interaction due to the dual effects in terms of disjunctive relation and counterfactual conditionals. I expect my account of disjunctive relation and counterfactual conditionals to contribute not just to several problems the received theories of causal modelling confront but also to the structural equation models many people exploit as a promising statistical methodology.

확률적 인과론은 확률관계를 통해 인과 관계를 밝히려는 이론이다. 그런데 만약 단지 C가 E의 발생 확률을 높인다는 사실을 밝히는 것으로 그치지 않고 더하여 C가 E를 발생시키는데 얼마나 기여하는지 그 기여도도 밝힐 수 있다면 우리는 원인과 결과의 관계에 대하여 훨씬 더 많은 정보를 얻을 수 있게 될 것이다. 이 글에서 나는 빼기의 개념에 기반한 멜러나 엘스의 정량적 확률적 인과론들을 살펴본 후 그 이론들이 인과적 효과도나 인과적 연관도를 밝히는데 부적절한 이론들임을 보인다. 그 후 나는 인과적 효과도클 측정하는데 보다 적절한 공식을 제시하며 이 공식에 기반하여 인과적 연관도 또는 인과적 기여도의 공식도 제시한다.

The demand that needs 'Digital Legacy', a notion that an Internet user can transfer his private blogs, e-mail and financial assets to inheritors and party interested when he died suddenly in the accident, has been growing recently. This issue has become a social hot potato since Justine Ellsworth's father in USA sued Yahoo for the right to access his son's Yahoo e-mail account after Justine Ellsworth had died in Iraq, in November, 2004 and the problems happened to deal with suicide-related blogs and homepages when great entertainers in Korea committed suicide and soldiers' parents in the situation of warship Chonan tragedy in Korea demanded access to soldiers' homepages and e-mail accounts. The point at issue focuses on the property matters about the digital information of the deceased and the relationship between the deceased and the Internet Service Provider(ISP). This research looks into the trend of judicial precedents and laws related to the digital information of the deceased and suggests the preliminary data of the next research.

Although a study on documentation strategy has been steadily releasing recently in the archival study field, it is rare that the cases or studies applying the institutional functional analysis methodology that Helen Samuels had suggested. The institutional functional analysis is a methodology to provide a comprehensive understanding of the record by defining the essential features of the institution at a macro level. The documentation area derived from the institutional functional analysis functions as a priori framework for an archivist to select and keep the records of the institution. In other words, by analyzing the function of the institution through the institutional functional analysis methodology, it makes possible to identify the functions not covered under the current records retention schedule at a macro level ensuring accountability of the organization's business activities. The documentation project of the United States is a prime example to comply with this background. In this study, by analyzing the case of the United States Congress, it is proposed the derived implications for applying the institutional functional analysis to the National Assembly of the Republic of Korea, where is the similar national institution to the U.S. Congress. For this purpose, firstly, the theoretical debate on the institutional functional analysis as the previous studies. Secondly, the documentation project of the United States Congress has been case analyzed by each function according to the institutional functional analysis. Thirdly, on the basis of the case study results, the implications are derived and it is suggested that the documentation areas applicable to the National Assembly of the Republic of Korea.
