Carbon costs, either in the form of a carbon tax or through permit prices in an emissions trading scheme, would ultimately be reflected in higher electricity prices. This price "pass-through" is very critical to the effective design of new policies to curb the amount of carbon emissions. This paper sets out in a structured way the factors that determine price pass-through and how carbon costs would impact on the electricity market and the existing coal-fired power plants. It is shown that pass-through can vary drastically if the underlying dispatch potential of generators varies significantly across alternative emissions reduction scenarios. It can also vary depending on the availability of competing cleaner forms of generation. Pass-through as a measure of business performance is therefore hard to generalize across different circumstances and should be interpreted carefully.

Quantity discounts provide a practical foundation for supply chain inventory policies, improving the supplier's profit and reducing the buyer's inventory cost simultaneously. Traditional quantity-discount research, which deals with inventory coordination between a buyer and a supplier, is extended to a stationary stochastic environment. This research shows that the magnitude of the optimal discounts scheduled by the deterministic quantity discount models may not be large enough to cover the buyer's additional inventory stocking risks under uncertain conditions. As a result, the buyer's total inventory cost may often increase rather than decrease. In contrast, the proposed model allows the supplier to identify the discount level, which shares the buyer's amplified risk associated with temporary overstocking and ensures that both buyer and supplier benefit economically. The performance of the proposed model was tested in the continuous review environments via numerical experiments. The experimental results support the proposed method as a feasible alternative in coordinating inventory decisions under stochastic demand.

According to increasing dependancy of national competitiveness on her level of science and technology, the Korean Government devote herself to expansion of technological capability in nation-wide. As a result, the numbers and sizes of national R&D programs, one of public technology policies, are abruptly increased. Recently, the government closely examines the introduction of performance-based budgeting regime as well as the accountability issue in public sector. In the fulfillment of accountability, it has considerable importance that the government executes measurement and strategic management of their performances of all the national R&D programs, how they are properly executed in conformity with respective missions and characteristics. It needs a tool for clearly measuring the programs' performances. In this study, the Balanced Scorecard (BSC) is suggested as an alternative. However, the logics of ordinary BSC cannot be directly applied to the program unit. This study reviews the basic concept and principles of BSC and discusses the necessary conditions for proper application of BSC into national R&D programs.

This paper is to explore that there are structural problems in the Korea-U.S. Free Trade Agrement negotiation by examining the Korean FTA policy and to introduce some alternatives to overcome them. The structural problem stems in part from the inefficient system in FTA policy making and its implementation. Most importantly, there is a lack of ex-ante consensus building among stake-holders. As an alternative to the current FTA policy, we suggest two things. First, we argue that an FTA negotiation strategy should correspond to Korea's overall industrial development strategy. Second, the National Assembly should play an important part for enforce of trade policies as a tool for advancing a comprehensive strategic measures.

The public has negative understanding about dam construction nowadays although dam plays an important role in water supply to satisfy essential demand for living. Dam rehabilitation, in this actuality, has been recognized as an alternative to expedite continuous water policies related to irrigation and flood control. This study focused on dam rehabilitation and included its necessity and discussions on case histories associated with increasing reservoir capacity, spillway modification, overtopping protection, seepage control and improving stability of old dam. This paper, in geotechnical aspects, presents discussions of various rehabilitation methods and factors to be considered in designing dam rehabilitation.

Thanks to superior leakage energy efficiency compared to SRAM cells, STTRAM cells are considered as a promising alternative for a memory element in on-chip caches. However, the main disadvantage of STTRAM cells is high write energy and latency. In this paper, we propose a low-cost write filter (WF) cache which resides between the load/store queue and STTRAM-based L1 data cache. To maximize efficiency of the WF cache, the line allocation and access policies are optimized for reducing energy consumption of STTRAM-based L1 data cache. By efficiently filtering the write operations in the STTRAM-based L1 data cache, our proposed WF cache reduces energy consumption of the STTRAM-based L1 data cache by up to 43.0% compared to the case without the WF cache. In addition, thanks to the fast hit latency of the WF cache, it slightly improves performance by 0.2%.

Compliance with information security policies has been an important managerial concern in organizations. Unlike traditional general deterrent theory, this study proposes whistle-blowing as an alternative approach for reducing internal information security policy violations. We build on the theories of planned behavior and rational choice as well as develop a theoretical model to understand the factors that influence whistle-blowing attitudes and intention at both the organizational and individual levels. Our empirical results reveal that altruistic and egoistic concerns are involved in the development of whistle-blowing attitudes. The results not only extend our understanding of whistle-blowing motivation but also offer directions to managers in promoting internal disclosure of information security breaches.

The HVAC takes the most important role in the Electric Multiple Unit for maintaining the healthy and comfortable indoor environment, however we also should consider the outdoor environment in terms of "environment's friendly" because the refrigerant used for the HVAC system is strongly related with the issues of "the Protection of environment" such as "the Global Warming" and "The Ozone layer Depletion". Therefore we survey (1)the potentially harmful impact on human health and the environment through modification of the ozone layer and the Green house effect, and (2)the international and the domestic environment's policies and (3)the potential alternative refrigerants usable for the EMU HVAC in terms of "the environment friendly properties", "the performance" and (4) "the applicabilities of the refrigerant for the EMU HVAC".

The official talks on the amendment of the Korean - Japanese Fisheries Agreement which was concluded in 1965 are under way since 1996. The convention area of the existing fisheries agreement is the high sea, but it should be changed to the exclusive economic zone(EEZ) for the newly amended fisheries agreement. Accordingly, the fundamental policies to be embodied within the amended fisheries agreement are summarized as follows : 1. One of the basic doctrine of the new agreement should be the formulation of a device of international cooperation for the fishery development as well as the conservation and management of the fishery resources. 2. The preparation of the future-oriented international relationship which reflects the specific character of the fishery relationship between both countries. 3. The existing fishery results of both parties should be protected on the ground of the reciprocity principle. 4. Both parties should reach an agreement upon the joint conservation and management measures for the transboundary fishery resources. 5. In consideration of the difficulty of EEZ delimitation between both countries, a provisional fisheries agreement can be an alternative measure.

A spatial decision making process is needed when a local government tries to make polices and plans for eco-tourism in urban and regional site scale. This study aimed to suggest an assessment model to support spatial decision making on planning and making polices for eco-tourism. The model composes 6 stages of 'setting up ecogeographic territories'. 'value analysis method as ecotourism resources' 'synthetic assessing', 'grading values', 'selecting main resources for ecotourism' and 'spatial decision making support'. Applying the model to Shiheung city in Kyounggi province, validity was secured. By using the model, it was possible to make some decisions effectively such as selection of ecotourism resources, decision of the priorities of polices for ecotourism, and setting up the type of ecotourism to be introduced. In addition, by visualizing high valued resources and areas for ecotourism it w possible to support to make plans and policies effectively.
