In response to climate change, Korea is attempting to shift the paradigm of energy and climate change policies by introducing carbon pricing based on market mechanisms. While policy adoption is proceeding at a rapid pace, the introduction of carbon pricing has been faced with great opposition from industry. This study measures to what extent Korean companies understand and accept carbon pricing, using data from a questionnaire survey covering energy consuming companies in 2012, when discussions between the government and such companies about the introduction of a domestic emission trading system were active. It further identifies how preparations and practices for carbon and energy management of companies correlate with their policy understanding and acceptance. The analysis results show that the surveyed companies indicate moderate understanding of, as well as resistance to carbon pricing policies, while appreciating the economic incentives and accepting the mandatory regulations in this phase. Companies' understanding is more related to characteristics, i.e., sector, size, etc. than external pressures. This study found that the extent to which companies understand policy is the essential factor in their policy acceptance and related practices. In particular, understanding of carbon policy significantly influences their managerial practices and voluntary activities for carbon and energy practices. This study substantiates the correlation between the level of policy understanding of a company and its carbon and energy practices - something that all countries seeking to introduce carbon pricing in response to climate change should consider prior to policy actually being implemented; in other words, enhancing the understanding of major policy subjects of the new instrument is a key policy strategy that should be elaborated as it will lead to better performance of companies and smoother policy implementation.

The goal of impact studies (e.g., as mandated by NEPA in the USA) is to ensure that the full implications of development proposals (ecologic, economic, and social) are taken into account before decisions are made and projects are allowed to proceed. In other words, the aim is to ensure that impact assessment is integrated into planning and policy processes. Today. nearly 25 years after the enactment of NEPA, it is appropriate to inquire regarding the extent of progress toward such integration. This paper examines the role of impact assessment in planning and policy processes with specific reference to resource development projects in the Great Plains region of the USA. The author gives special attention to the socioeconomic impacts associated with energy resource extraction and conversion projects and the role of impact assessment in project evaluation, in local and regional planning, and in state policy development.

This paper considers the replacement model and the preventive maintenance model following the expiration of combination warranty for a repairable system. If the system fails after the combination warranty is expired, then it is minimally repaired at each failure. The criterion used to determine the optimal replacement policy and the optimal preventive maintenance policy is the overall value function based on the expected cost rate per unit time and the expected downtime per unit time. The numerical examples are presented for illustrative purpose when the failure time follows a Weibull distribution.

In ordo. to establish cataloging procedures for non-book materials(NBM), library has In make policy decisions which will apply to all materials. This study explores problem areas in bibliographic control and descriptive cataloging for NBM and issues to be decided in cataloging policy for NBM are presented. Recently proposed KORMARC Rules for Descriptive Cataloging, NBM is looked into and compared with AACR2R and some problems to be considered for revising are suggested. Principle and tools needed for subject analysis of NBM are discussed and special issues of subject analysis for NBM are presented.

This paper analyses the effects of mobile telecommunications market's interconnection charge on consumer welfare between 2000 and 2010 by estimating price elasticity of demand with using log linear model and augmented Alexander et al(2000)'s model. The results show that consumer welfare is about 6 trillion won in 2009 and an upward trend. In the 2nd analysis, the decline in interconnection charge raise consumer welfare but, asymmetric interconnection and current TD-BU LRIC system have negative(-) relation with consumer welfare. Hence we need to revise interconnection policy frame.

본 연구는 2011년 "원자력안전법" 제정 사례에 있어 정책의제 설정 과정을 동태적으로 이해하기 위해 다중흐름모형을 활용하여 분석을 수행하였다. 연구범위는 이명박 정부와 제18대 국회임기가 겹치는 기간인 2009년부터 2011년 간 기간으로서, 동 기간은 UAE 원전수출과 후쿠시마 원전사고라는 정 반대의 초점사건이 발생하면서 두 차례 의제설정 여부를 결정하는 정책의 창이 개방되었다. 분석결과, 문제의 흐름 영역에서는 정부의 원자력 정책에 있어 진흥과 규제기능을 별도 법령으로 분리하고 독립된 예산 및 전담조직을 구성하는 체계를 구축해야 한다는 문제는 장기간 존재해왔다. 1990년대부터 소수의 법학자들을 중심으로 문제인식과 대안제시가 이뤄지는 정책의 흐름이 발전되어 왔는데, 이후 UAE 원전수출 이후 2010년에 이르러서야 본격적으로 표출집단인 관료와 국회의원을 통해 구체적 대안이 제시되었고, 2011년 후쿠시마 원전사고 직후인 5월 원자력안전법이 제정되었다. 분석결과, 2009년 UAE원전수출 이후, 수출 확대 목적으로 제시된 원자력 규제 독립 법안이 통과되지 못했던 것에 반해, 2011년 후쿠시마 이후 원자력안전법이 통과 된 이유는 대안의 가치정합성, 사회여론, 정치환경 등 정치의 흐름이 크게 작용한 것으로 분석되었다.

In this paper. we develop an analytical model to evaluate the virtual topology reconfiguration phase of optical Internet networks. To counter the continual approximation problem brought by traditional heuristic approach, we take the traffic prediction into consideration and propose a new heuristic reconfiguration algorithm called Prediction based Multi-stage Reconfiguration approach. We then use this analytical model to study the different configuration operation policies in response to the changing traffic patterns in the higher layer and the congestion level on the virtual topology. This algorithm persists to decide the optimal instant of reconfiguration easily based on the network state. Simulation results show that our virtual topology management Policy significantly outperforms the conventional one, while the required physical resources are limited.

Development of policy incentives and policy direction in the innovation economy is always important. Innovations policy have characterized industrial dynamics, leading to a transformation of the market structure of the specific industry. The paper explores the development of industry convergence for understanding the change of the wireless industry in Daejeon. Although its initial focus is R&D center, The business model has become the research and development of external demand than its own product research and development. For regional innovation, the wireless industry policy should be provided with their own product development pattern.

클라우드 환경을 구성하는 자원을 능동적으로 사용 하기 위해서는 부하분산 정책이 필요하며 효율적으로 작업을 할당하고 공유할 수 있는 자원 관리 스케줄링이 필요하다. 또한 자원의 경제성을 유념하여 클라우드 서비스 제공자의 이익 창출과 자원 활용도의 개선을 실현해야하고 서비스 사용자의 만족도를 향상시켜야 한다. 본 논문에서는 계층형 부하분산 정책을 이용한 비용이익 기반 자원관리 스케줄링 모델(Cost-benefits Based Resource Management Scheduling Model using Hierarchical Load Balancing Policy)을 제안한다. 제안하는 모델은 계층형 부하분산 정책을 적용하여 자원을 통합, 관리함으로서 개선된 유지보수성을 제공하며, 서비스 제공자의 비용이익을 고려하여 각 자원들마다의 자원협상 메커니즘과 비용이익을 우선으로 하는 가격 결정 알고리즘을 제공하여 합리적인 자원 할당이 가능하다.

The User Created Contents (UCC) are traded actively on the on-line market. The current pricing policy on the UCC market is the fixed pricing, which is set by the seller once and price never changes again. However market demand and supply are changing hourly, so the studies about dynamic pricing to determine more properly have been carried out. This paper suggests dynamic pricing models for UCC by analyzing the customer's searching pattern. We propose 2 pricing models (trend change-based pricing model and relative pricing model), and experiment various status by controlling system and market variables. We demonstrated our model by computational modeling and simulation. The result of this research can be useful guidelines to increase the revenue and profit of the UCC Market.
