에너지정책 거버넌스의 변화에 관한 고찰

김호철,Kim, Ho-Chul 한국자원경제학회 2007 자원·환경경제연구 Vol.16 No.2

한국의 에너지 부문은, 정부가 정책과정을 독점하는 가운데 명령과 통제 메커니즘에 입각하여 시장과 시민사회를 규율하는 행정국가형의 관료제 거버넌스가 현저한 부문의 하나였다. 이러한 거버넌스 체제 아래 정부는, 공기업을 통하여 에너지를 직접 공급하는 한편, 광범위한 공적 규제들을 활용하여 시장행동을 규제하였다. 그러나 한국 에너지 부문의 거버넌스 체제는, 1993~2002년 기간 중에 정부의 신자유주의적 개혁이 추진되면서 '시장주의 거버넌스'로 전환되는 변화과정을 걸었다. 이러한 시장주의적 개혁은 신자유주의 이념에 기반하는 것으로서, 정부와 명령-통제 메커니즘에 비하여 시장과 경쟁 메커니즘이 사회적 문제의 해결에 보다 도움이 된다는 인식에 기초한다. 이러한 패러다임 아래 정부는, 에너지 공기업의 구조개편과 규제의 완화를 통하여 정부의 몸집과 영향력을 줄이기 위한 개혁을 추구하였다. 또한 2003년에 출범한 현 정부 아래서는, 그간의 정책과정에서 소외되었던 시민사회를 중심으로 에너지정책과정의 폐쇄성과 이에 따른 정책실패의 가능성에 대한 비판이 거세지면서, '참여주의 거버넌스'를 지향하는 개혁이 추진되고 있다. 이러한 거버넌스 레짐의 전환은, 개방적인 상호작용과정은 자기조직성을 가지며 따라서 참여적 정책과정이 사회적 문제의 해결과 갈등의 해소에 보다 효과적으로 기여한다는 인식에 기초한다. Korea's energy sector was one of policy sectors that exhibited the classical bureaucratic governance of an administrative state. Under the regime, government monopolized the policy-making process and controled the market and the civil society. It not only provided energy goods and services directly through public enterprises but also dominated the market activities through public regulations. However, during 1993~2002, stringent reformation efforts were made to transform the governance regime from the past bureaucratic model to the market model, by way of privatization of public enterprises and deregulation. The ideology behind the reformation based on the shared recognition that the market and spontaneous order thereof is the better apparatus than the government and artificial order thereof in solving social problems mote efficiently. From the year of 2003, another round of reformation efforts have been promoted to introduce the participatory governance model, through institutionalization of channels for the wider participation of civil society into the energy policy-making process. This reformation efforts respond to; first, the increasing criticism from the civil society on the closedness of energy policy process and the higher probability of policy failures thereof, and second, the recognition that the self-organizing nature of an open policy process is the better mechanism for evolutionary problem-solving.

This paper is based on our comments and proposed amendments to the documents, Annex A, Phantom for determining Maximum Depth of Penetration, and Annex B, Local Dynamic Range Using Acoustical Test Objects 87/400/CDV. IEC 61391-2 Ed. 1.0 200X, prepared by IEC technical Committee 87; Ultrasonics. The documents are concerned with the influence of microstructure of reference target material on the ultrasonic backscattering. Previous works on the attenuation due to backreflection and backscattering of reference target materials are reviewed. The drawback to the use of ungraded stainless steel and metallic materials without microstructural data such as, crystal structure, basic acoustic data of sound velocity and attenuation, grain size, roughness and elastic constants has been discussed. The analysis suggested that the insightful conclusion can be made by differentiating the influence arising from target size and microstructure on the backscattering measurements. The microstructural parameters are associated with physical, geometrical, acoustical and mechanical origins of variation with frequency. Further clarification of such a diverse source mechanisms for ultrasonic backscattering would make the target material and its application for medical diagnosis and therapy simpler and more reliable.

코이어 배지(코코넛 분말:섬유=70%:30%, v/v)를 이용한 착색단고추 수경재배에서 공급 배양액의 적정 농도를 구명하고자 EC 2.5, 3.0, 3.5 및 4.0dSㆍm?¹의 농도를 공급하였다. 생육 기간 동안 배양액의 급액 농도에 따른 슬라브내의 EC는 급액 농도가 높아지면 증가하는 경향을 보였으며, 수분 함량은 반대의 경향을 보였다. 배액의 pH는 안정적이었으며, EC는 급액 농도 EC 4.0dSㆍm?¹에서 EC 7.3dSㆍm?¹로 높았을 뿐만 아니라 표준편차와 변이계수도 높았다. 초장은 급액농도 간 큰 차이를 나타내지 않았다. 광합성율은 급액 농도 EC 4.0dSㆍm?¹에서 전반적으로 높았다. 과중은 급액 농도 EC 4.0dSㆍm?¹에서 가장 무거웠으며, 과형은 급액 농도 EC 3.5dSㆍm?¹에서 정사각형에 가까웠다. This experiment was carried out investigation of optimum concentration of supply nutrient solution in hydroponics of sweet pepper using coir substrates (coconut dust : fiber=70% : 30%, v/v). During the growing period, it was found out that the electric conductivity (EC) would increase in proportion to the supply nutrient concentration but it was in inverse proportion to the moisture content. The pH of drainage was stable, while EC was high showing EC 7.3 dSㆍm?¹ in EC 4.0 dSㆍm?¹ of supply nutrient concentration. Also, standard deviation and coefficient of variation were high. Plant length was no difference by the supply nutrient concentration. Photosynthesis rate was generally high in supply nutrient concentration EC 4.0 dSㆍm?¹. Fruit weight was heavy in supply nutrient concentration EC 4.0 dSㆍm?¹, fruit shape was close to a regular square in supply nutrient concentration EC 3.5dSㆍm?¹.

The purpose of this study is to evaluate the residential environment improvement program as an alternative for housing renewal program implemented under the principle of profit maximization. The housing renewal project has led to various problems such as the lack of urban infrastructure the aggravation of urban environment, and the displacement of low-income residents in renewal areas. The residential environment improvement program implemented by a multi-family housing building method was introduced to mitigate physical and socio-economic problems resulted from the housing renewal project. The evaluation of the multi-family housing building method would provide the policy direction on residential improvement of the low-income community. In evaluating the method, this study focuses on a few key variables including the floor-to-area ratio indicating the physical density and residents’ relocation rate representing socio-economic stability due to the problem of data availability. This study found that there was no substantial improvement in physical and socio-economic conditions in project districts by the multi-family housing building method. This finding implies that there is no difference between the residential environment improvement program by the multi-family housing building method and the housing renewal project in terms of project outputs. The policy to improve urban blighted areas should consider public financial supports and community-based renewal method which would mitigate negative effects led by existing residential renewal projects.

Angiogenesis is closely assocatied with bone formation and osteoporosis is risk factor of success of implant. Recently reported, uptake of calcium and Vitamin D improve bone healing process in osteoporosis. Vascular endothelial growth factor also interact bone formation through modulation of angiogenesis. The purpose of this study was to evaluate the interaction between vascular endothelial growth factor (VEGF) and calcium with vitamin D in bone tissue around implant in osteoporosis induced rats by measuring the expression of vascular endothelial grawth factor receptors (VEGFR). Titanium screw type implants were placed into tibias of ovariectomized. The rats were sacrificed at different time interval (1,2 and 4 weeks after implantaion) for immunohistochemistry with antibody for receptor of vascular endothelial growing factor 1, 2 and 3. In this study we observed 3 type vascular endothelial growth factor (VEGFR1-3). Receptor of vascular endothelial growth factor 3 (VEGFR-3) was increased by calcium and vitamin D in bone formation process but others (receptor of vascular endothelial growth factor 1 and 2) were not shown significant difference. This study, with previously published work, shows that VEGF interact with calcium and vitamin D and especially VEGFR-3 was incresed in early stage.
