  • 배출권 이월 및 차입은 감축기술개발투자에 영향을 미칠 수 있다. 배출권거래제하에서 이월 및 차입이 허용되면 감축비용과 배출권 가격에 따라 배출권거래제 참여기업들은 현재의 감축을 미래로 또는 미래의 감축을 현재로 선택할 수 있기 때문에 배출권 이월 및 차입은 감축기술개발에 대한 대체재적인 역할을 한다. 따라서 배출권 이월 및 차입과 같은 간접감축이행수단을 허용하는 경우에는 직접감축이행수단인 감축기술개발투자에 영향을 미친다. 불완전경쟁시장에서 이러한 간접감축조치가 감축기술개발투자에 미치는 영향은 완전경쟁시장하에서와 달라질 수 있다. 왜냐하면 과점시장의 쿠르노 경쟁하에서 감축기술개발투자가 최종소비재시장의 균형에 영향을 미칠 수 있기 때문이다. 분석 결과, 배출권 이월 및 차입으로 인한 감축기술개발투자 유인 수준은 감축비용, 할인계수, 초기무상할당, 감축기술개발투자효과 등에 의존한다.

  • Dynamic responses of electrorheological (ER) fluids in steady pressure flow to stepwise electric field excitations are investigated experimentally. The transient periods under various applied electric fields and flow velocities were determined from the pressure behavior of the ER fluid in the flow channel with two parallel-plate electrodes. The pressure response times were exponentially decreased with the increase of the flow velocity, but increased with the increase of the applied electric field strength. In order to investigate the cluster structure formation of the ER particles, it was verified using the flow visualization technique that the transient response of ER fluids in the flow mode is assigned to the densification process in the competition of the electric field-induced particle attractive interaction forces and the hydrodynamic forces, unlike that in the shear mode determined by the aggregation process.

  • Product Liability(PL) is a legal policy to deal with global competition by improving domestic industrial competitive power and to reduce the cost of defect products. The purpose of this paper is to address the state of the art solutions to dispute on PL, in reality of a frequent occurrence of global product exchange focussing on product safety that is one of the most important functions of PL and to improve solution of the product safety and reliability responsive to PL. To minimize PL exposure, manufacturers should reflect comprehensive product safety and reliability concepts in establishing PL prevention policies. Total PL prevention policies are composed of total quality management and product safety management system in respect of safety design, risk, and reliability. These PL prevention activities should be performed consistently during the total product life cycle, especially product research and development periods.

  • Nowadays the marketing environment has become an important factor which should be seriously considered by all the managers of modern firms. The survivals of modern firms are basically influenced by the changes of marketing environment. Particularly, it is necessary for firms to pursue the rational and efficient managerial activities since the recent environment is characterized by the stiff competition and rapid changes. First of all, this paper is trying to theoretically examine how the environment of the marketing system has been changing in terms of different periods and macro-levels. Secondly, in order to understand the patterns of consumers' perceptions on the environmental changes, some hypotheses have been established and relevant data have been collected. And, in order to analyse the results of this study, the followings have been implemented : Pilot analyses on the experimental environment and variables, the selection of research methodology, the test hypotheses, and the summary of the results. Finally, some practical implications have been suggested in order to help marketing managers formulate the efficient marketing strategic.

  • Barnyardgrass had relatively higher growth vigor at the earlier growth stage than inbred rice did, showing the 2 fold higher $\alpha$-amylase activity during the periods of germination and large leaf area Expansion with high net photosynthetic rate at the earlier autotrophic stage, but it performed weak growth at the late growth stage. However, the hlybrid rice Shanyou 63 had significantly higher $\alpha$-amylase activity and net photosynthetic rate than that of barnyardgrass, exhibiting heterosis for two physiologica1 traits during the germination (6~12 days) and autotrophic phase, respectively. Accordingly, hybrid rice, Shanyou 63, exhibited heterotic effect at the early growing stage when were presented with barnyardgrass. Shanyou 63 exhibited stronger tillering ability, faster leaf area expansion and higher net photosynthetic rate than those of barnyardgrass.

  • This paper addresses the bidding strategies of a pumped-storage hydro plant in an electricity market. Competitive bidding of pumping and generating of a pumped-storage plant is formulated in a game theoretic problem in accordance with the three different ownership of scheduling; Market Operator(MO), generating company(Genco), and combined type of MO and Genco. Optimal conditions for Nash Equilibrium are derived in the form of market prices during the scheduling periods. Simulation results show the different ownership models produce different schedules of pumping and generating, which correspond to the objective of the scheduling owner of a pumped-storage hydro plant.

  • In this paper, we develop theoretical game models to determine the level of government subsidies for banks to provide policy loans to Innovative SMEs(small and medium sized enterprises) through banks, which otherwise would not finance them for the sake of their own profitability. For this, we compare net cash flows of each bank using different strategies against high risk innovative SMEs. A bank can decide whether to provide them loans or not In each period. Following Kim(2003)'s Infinite horizon model on the soft budget constraint, we introduce a situation in which banks compete against each other for higher net long-term payoffs from their loans to innovative SMEs and non-innovative SMEs. From the models, we show that competition among banks in general leads to a tighter decision against innovative SMEs, as a Nash equilibrium. It is not because the government bank is simply loose in providing loans, but because competition among commercial banks for fewer riskier borrowers results in tighter loan decisions against innovative SMEs. Thus, the competitive market for policy loans to innovative SMEs fails to reach the socially optimal level of loans for innovative SMMs. Commercial banks in the competitive market may require additional supports from the government to make up for the differences in their payoffs to support innovative SMEs, possibly much riskier due to moral hazards and poor discounted cash flows. The monopolistic government bank might also request such supports from the government to fund otherwise unqualified SMEs. We calculate an optimal level of governmental support for banks to guarantee funding such high-risk innovative SMEs over periods without deviating from their optimal Nash equilibrium policies.

  • 고농도 황산염과 중금속을 함유한 피혁폐수를 처리하기 위하여, 반응조의 처리도, 황환원균과 메탄균 사이의 기질경쟁 및 크롬농도에 대한 메탄균의 활성을 평가하였다. COD는 $35^{\circ}C$의 반응조 온도에서 유기부하량 2.0 gCOD/l.day와 18시간의 수리학적 체류시간에서 70% 이상의 제거율을 얻을 수 있었다. 황환원균과 메탄균 사이의 기질경쟁에서 황환원균에 의해 이용된 COD는 운전초기 15%에서 실험종료시 43%까지 증가되었다. 이는 유기물 분해로부터 발생되는 대부분의 전자가 황환원균에 의해 이용되어 황산염 환원에 의한 황화물이 생성되므로 메탄균의 활성은 강력히 억제되었다. 전 실험기간 동안 크롬농도는 90% 이상 제거되었으며, 크롬농도의 높은 제거율에도 불구하고 반응조의 처리능력은 거의 감소되지 않았다. 이는 반응조내에서 제거된 3가 크롬이 미생물의 활성에 영향을 미치지 않은 점으로 볼 때 3가 크롬이 6가 크롬에 비해 미생물에 대한 독성영향이 심하지 않다고 볼 수 있다.
