In this paper, I have attempted to show how the environmental controversy surrounding the Saemangeurn Reclamation Project in Korea has been framed as narrow scientific debates. First of all, science, or specifically the Expert Review Pane, has played dual roles in the controversy. On the one hand, it has contributed to illuminating the future environmental impacts of reclamation, by so doing, to providing a momentum to reconsider the project. This has significant meaning that environmental concerns successfully checked the symbolic national project of developmental era through adopting a joint-investigation scheme that guaranteed participation of environmental groups on an equal footing with the government. On the other hand, by limiting the scope and participants of discussion, it fundamentally blocked the possibilities of public debates and deliberative decision-making with full considerations of the political, social, and cultural aspects of the controversy. I have shown that this is due to the realist belief shared by both the developers and the environmentalists in Korea that 'proper' science would disclose the truth. Environmental groups, in particular, were naive in evaluating the role of scientific expertise in the controversy and neglected the political role of the Expert Review Pane as a ritual. In opposition to the realist argument, I have shown through the analysis of the water quality debates concerning the future fresh water lakes that scientific 'facts' were not discovered but constructed through complex negotiations, conflicts, and compromises among related actors. The framing of the controversy as an experts' debate has resulted in the exclusion of an important actor from the discussion. Little attention has been paid throughout the controversy to the very people who have lived in the Saemangeum area for generations and will lose their livelihood all together soon. About 20,000 fishermen are living on the Saemangeum tidal flats.

This paper presents a new copy network for multicast ATM switches. Many studies have been carried out up to date since the proposition of Lee's copy network. However, the overflows and cell conflicts within the switch have still been raised a problem in argument. In order to reduce those problems, we proposed a 3-dimensional multicast switching architecture which has shared buffers in this paper. The proposed architecture can reduce the overflows and cell conflicts through multiple paths and output ports even in the high load environments. Also, we proposed a cell splitting algorithm which handles the cell in the case of large fan-out, and a copy network to increase throughput by expanding the Lee's Broadcast Banyan Network(BBN). Cell copy uses the Boolean interval splitting algorithm and the multicast pattern of the cells according to the self-routing characteristics of the network. In the proposed copy network, we improve the problems such as overflow, cell splitting of large fanout, cell conflicts, etc., which were still existed in the Lee's network. The results of performance evaluation by computer simulation show that the proposed scheme has better throughput, cell loss rate and cell delay than the conventional method.

This study aims to review and evaluate the changes of the British social housing policy under the Conservative government(1979-1997), and to get some implications for the Korean case. The Conservatives tried to diminish the role of state in the realm of social welfare :in general, and to retreat the social housing policy in particular as a reaction to the' welfare state crisis' started from the early 1970s. In the realm of housing policy, privatisation and marketisation including the massive sale of council houses were driven enthusiastically. Public expenditure cut and redirection of the housing subsidy scheme were also implemented according to the changed policy orientation. The clear visible results of the policy changes can be seen as follows; radical changes of the housing tenure distribution, changing role of local authorities, and the worsening housing problems- housing shortages, residualisation, affordability problem, deepening dependency and the negative distribution of housing subsidy etc. Furthermore the goal of public expenditure cut, in fact, was not accomplished successfully. The results of this study support the argument that the Neo-liberalistic approach to the 'welfare state crisis' have resulted in reconstruction and redirection rather than total abolition of the role of state in welfare provision. This conclusion could provide important implications to Korean case, especially concerning the role of state in the social housing policy.
